Title: Fluid processing apparatus and method of controlling the same

Description:
CROSS-REFERENCE TO RELATED APPLICATION(S) 
     This application is based on and claims priority of Korean Patent Applications No 10-2021-0002012 filed on Jan. 7, 2021 with the Korean Intellectual Property Office, the entire content of which is hereby incorporated by reference. 
     TECHNICAL FIELD 
     This disclosure relates to a fluid processing apparatus and method of controlling the same, and more particularly, to a fluid processing apparatus configured to allow a user to easily mix various fluids in a desired ratio, and easily heat or cool a fluid to be used to an appropriate temperature, and a method of controlling the same. 
     BACKGROUND 
     The term “cosmetics,” “cosmetic product,” or “cosmetic composition” is one that collectively refers to creams, powders, perfumes, etc. used by users for makeup or caring skin, hair, eyelash, and/or eyebrows. Conventionally, cosmetics have been used for the purpose of making user&#39;s appearance more beautiful, but recently, they are used not only for the appearance itself but also for health purposes such as skin care. 
     Most cosmetics on the market are assumed to be used individually. In general, each cosmetic product is manufactured with different ingredients, and a user selects and uses a cosmetic product according to a desired effect. 
     As the trend of our society changes toward reflecting personal needs, the cosmetic product market also begins to follow this trend. That is, an increasing number of users not only purchase and use a single cosmetic product that has already been manufactured, but also mix a plurality of cosmetic products to manufacture their own cosmetic product by themselves. 
     Conventionally, various cosmetics in the form of finished products are put into a plurality of cartridges of a cosmetic mixing apparatus, respectively, and a user pumps the device to make it discharge each cosmetic product as much as the user wants. The discharged cosmetic products are mixed directly by the seller or customers and provided to the customers. 
     However, this type of cosmetic mixing apparatus has various drawbacks. 
     First, they are concerned with the method of discharging a cosmetic product. When the cosmetic product is discharged by the pumping method, there is a concern that the residual cosmetic product remains in the cartridge and the pumping apparatus. Considering that cosmetics are compounds that can be contaminated with changes in the surrounding environment, this problem may affect the freshness of the cosmetic product 
     Also, the drawbacks are concerned with the way in which cosmetics are mixed. The various types of cosmetic products discharged by the pumping method are mixed by the seller or customer, who, during this process, uses hands or tools. In addition to the problem of cleanliness management of tools, there is also the possibility that the cosmetic product may be contaminated by bacteria, etc. when the cosmetic product is mixed by hand. 
     Furthermore, there is also a problem that it is difficult to diversify the effects of the mixed cosmetic product. That is, there is a limit to the types of cosmetic products that can be discharged and provided by a pumping method. Therefore, it is difficult to diversify the effect that can be provided to the user by mixing, and thus it is difficult to accurately reflect the user&#39;s needs. 
     Accordingly, various techniques for effectively mixing cosmetic products and providing the resultant cosmetic product to customers have been introduced. 
     Korean Patent No. 10-1741575B1 discloses a cosmetic mixing apparatus capable of adjusting the mixing ratio. Specifically, it discloses a cosmetic mixing apparatus having a structure in which a plurality of cartridges loaded with a plurality of liquid cosmetic products, respectively are pressed with a push bar to discharge the cosmetic products, and the discharged cosmetics are mixed in a mixing device. The prior document discloses the effect of adjusting the proportion of cosmetic products according to the degree of pressurization of the push bar provided in the cartridge. 
     However, the cosmetic mixing apparatus having such a structure has a drawback that the discharge rate of cosmetic products must be adjusted by the user. That is, since the discharged amount of cosmetic product is adjusted according to the force with which the user presses on the push bar, there is high possibility that cosmetic product of an unwanted proportion may be manufactured by the user&#39;s erroneous operation. 
     Korean Patent No. 10-1317425B1 discloses a disposable cosmetic mixing container. Specifically, it discloses a cosmetic mixing container for one time use that has a structure in which by mounting an ampoule containing a certain amount of raw material into the ampoule insertion port provided in the main body, different kinds of raw materials can be discharged into the inner space of the main body and be mixed therein. 
     However, the cosmetic mixing container of this structure has a drawback that the ampoule containing the cosmetic product must be repurchased every time. That is, the ampoule disclosed in the prior document is pre-manufactured and sold by the manufacturer, and thus there is a concern that the variety of cosmetic products that can be manufactured by a user may be reduced. Additionally, the cosmetic mixing container disclosed in the prior document is in a form in which the upper side thereof to which the ampoule is coupled is always open, and it is difficult to exclude the possibility that foreign substances such as dust are introduced thereinto. 
     Furthermore, in the case of the prior document, there is also a drawback that a user can no longer use it when the structure of the product is changed due to the situations of the manufacturer.

In addition, as described above, the plurality of selection buttons  131  may be provided, and may be disposed to be spaced apart from each other in an arc direction of the front cover  130 . In this case, the button opening  132  may be located below the selection button  131  located in the center. 
     As will be described later, the main button  411  may be manipulated by a user to receive a control signal for starting or ending the operation of the fluid processing apparatus  10 . That is, the main button  411  may be served as a kind of power button.

     In the shown embodiment, the withdrawal opening  133  is located below the button opening  132 . As will be described later, the fluid processed by the operation of the fluid processing apparatus  10  is received in the tray  170 . At this time, in order to minimize the power required to convey the fluid, it is preferable that the tray  170  is located at the lower side as much as possible.

     The rear cover  140  is coupled to the support frame  150 . 
     The support frame  150  removably supports the fluid receiving part  200 . Additionally, the top cover  110  is removably coupled to the support frame  150  to prevent the fluid receiving part  200  from being arbitrarily exposed to the outside. Furthermore, the support frame  150  is coupled to the front cover  130 , the rear cover  140 , and the coupling frame  160 , respectively, to form a part of the housing  100 . 
     The support frame  150  is accommodated in the inner space of the housing  100 . Additionally, the support frame  150  partitions the inner space of the housing  100  together with the coupling frame  160  into a plurality of spaces. 
     In the shown embodiment, the support frame  150  partitions the inner space of the housing  100  into an upper space and a lower space. The upper space of the housing  100  is defined by being surrounded by the top cover  110  and the support frame  150 . The fluid receiving part  200  is accommodated in the upper space. The lower space of the housing  100  is defined by being surrounded by the bottom cover  120 , the front cover  130 , the rear cover  140 , and the support frame  150 . The conveying part  300  and the current carrying part  400  are accommodated in the lower space.

     The fluid receiving part  200  is penetratingly coupled to the support frame  150 . The coupling may be achieved by a plurality of support parts  151  and  152  formed in the support frame  150 . 
     In the shown embodiment, the support frame  150  has a circular cross section, and its outer periphery is formed in a band shape extending in a direction toward the coupling frame  160 , that is, downward. Accordingly, between the surface of the support frame  150  and its outer periphery, there is formed a predetermined space to which the coupling frame  160  may be inserted and coupled. 
     In the shown embodiment, the support frame  150  includes a main support  151  and a sub-support  152  (best shown in  FIGS. 9 and 10 ). 
     The main support part  151  supports a main container  210  of the fluid receiving part  200 . The main support part  151  is penetratingly formed in the thickness direction of the cross-section of the support frame  150 , such as, in the vertical direction in the shown embodiment. It will be understood that the direction in which the main support part  151  penetrates is the same as the direction in which the main container  210  penetrates or is withdrawn from the main support part  151 . 
     The main support part  151  is located on one side of the support frame  150  on the cross-section of the support frame  150 , such as being located biased toward the rear side in the shown embodiment. At this time, the sub-support  152  is located on the other side of the support frame  150  on the cross section of the support frame  150 , such as being located biased toward the front side in the shown embodiment. The position of the main support  151  may be changed according to the position of the main container  210 . 
     The shape of the main support  151  may be changed according to the shape of the main container  210 , and specifically, the shape of the cross-section of the main container  210 . In the shown embodiment, the front side of the main support  151  extends in the left and right direction, and the rear side thereof has a circular arc shape with its center located on the front side, and convex toward the rear side. That is, in the shown embodiment, the shape of the cross-section of the main support  151  is a semicircular shape. 
     The cross-sectional area of the main support  151  may be greater than that of the sub-support  152 . This is because the volume of the main fluid accommodated in the main container  210  inserted into the main support  151  is usually greater than the volume of the sub-fluid accommodated in the sub-container  220  inserted into the sub-support  152 . 
     The main support part  151  communicates with the main coupling part  161  of the coupling frame  160 . The main container  210  may be partially accommodated in the main coupling part  161  after penetrating the main support part  151 . 
     The sub-support  152  is located adjacent to the main support  151 .

The sub-support part  152  is penetratingly formed in the thickness direction of the cross-section of the support frame  150 , such as, the vertical direction in the shown embodiment. It will be understood that the direction in which the sub-support part  152  penetrates is the same as the direction in which the sub-container  220  penetrates or is withdrawn from the main support part  151 . 
     The sub-support  152  is located on the other side of the support frame  150  on the cross section of the support frame  150 , such as being located biased toward the front side in the shown embodiment. That is, the sub-support  152  is located biased in a direction opposite to the main support  151 . The position of the sub-support  152  may be changed according to the position of the sub-container  220 . 
     The shape of the sub-support  152  may be changed according to the shape of the sub-container  220 , and specifically, the shape of the cross-section of the sub-container  220 . In the shown embodiment, the sub-support  152  is formed to have a circular cross section. 
     A cross-sectional area of the sub-support  152  may be smaller than that of the main support  151 . As described above, this is because the cross-sectional area of the sub-container  220  coupled to the sub-support  152  is smaller than the cross-sectional area of the main container  210  coupled to the main support  151 . 
     The sub-support part  152  communicates with the sub-coupling part  162  of the coupling frame  160 . A portion of the sub-container  220  may be accommodated in the sub-coupling part  162  after penetrating the sub-support part  152 .

     A plurality of sub-support parts  152  may be formed. This is because a plurality of sub-fluids having different effects are respectively received in the sub-containers  220  coupled to the sub-support  152 , and are respectively mixed with the main fluid. The plurality of sub-support parts  152  may be disposed to be spaced apart from each other. 
     In the shown embodiment, the sub-support parts  152  are three, and include the first sub-support part  152   a  located on the left, the second sub-support part  152   b  located in the central portion, and the third sub-support part  152   c  located on the right.

The number and arrangement method of the sub-supporters  152  may be changed according to the number or the like of sub-containers  220  provided in the fluid processing apparatus  10 . 
     The support frame  150  is coupled to the coupling frame  160 . 
     The coupling frame  160  is removably coupled to the fluid receiving part  200 . Additionally, the coupling frame  160  is coupled to a valve member  330  of conveying part  300 . Accordingly, the fluid receiving part  200  coupled to the coupling frame  160  may be coupled to the valve member  330  to be in fluid communication therewith. 
     In addition, the coupling frame  160  is removably coupled to the support frame  150 , and forms a part of the housing  100 . In the shown embodiment, the coupling frame  160  is partially accommodated in the space formed between the end surface and the outer periphery of the support frame  150 . 
     The coupling frame  160  is accommodated in the inner space of the housing  100 . The coupling frame  160  partitions the inner space of the housing  100  together with the support frame  150  into a plurality of spaces. 
     In the shown embodiment, the coupling frame  160  partitions the inner space of the housing  100  into an upper space and a lower space. Since the description of the components accommodated in the partitioned upper space and the lower space has been provided above, it will be omitted. 
     The coupling frame  160  is removably coupled to the support frame  150 . In the shown embodiment, the coupling frame  160  is accommodated in the space formed inside the support frame  150 . Accordingly, it may be said that the coupling frame  160  is coupled to the front cover  130  and the rear cover  140  through the support frame  150 , respectively. 
     The fluid receiving part  200  is accommodated in the coupling frame  160 . This may be achieved by the plurality of coupling parts  161  and  162  provided in the coupling frame  160 .

     Additionally, it will be understood that the plurality of portions protruding downward among the portions of the coupling frame  160  are portions forming the plurality of coupling parts  161  and  162 . 
     The valve member  330  is penetratingly coupled to the coupling frame  160 . Specifically, an upper head part (no reference numerals) of the valve member  330  having a relatively large diameter is located inside the coupling frame  160 , and the rest part except the head part may be located outside the frame  160 . 
     In the shown embodiment, the coupling frame  160  includes the main coupling part  161  and the sub-coupling part  162 . 
     The main coupling part  161  is a space in which the main container  210  of the fluid receiving part  200  is partially accommodated. In the shown embodiment, the lower portion of the main container  210  is accommodated in the main coupling part  161 . Additionally, the main valve member  331  of the valve member  330  is partially accommodated in the main coupling part  161 . That is, a portion (i.e., the upper head portion) of the main valve member  331  may be located inside the main coupling part  161 . 
     Accordingly, the main container  210  coupled to the main coupling part  161  may be coupled to the main valve member  331  to be in fluid communication therewith. Accordingly, the main container  210  and the main valve member  331  may communicate with each other so that the main fluid received in the main container  210  may flow through the main valve member  331 . 
     The main coupling part  161  is a space formed by being partially surrounded by the coupling frame  160 .

In the shown embodiment, the horizontal direction sides of the main coupling part  161 , such as, the left, right, front and the rear sides, are surrounded by the coupling frame  160 . In addition, the upper side of the main coupling part  161  is opened and functions as a passage into which the main container  210  and the main valve member  331  can be inserted. Furthermore, the lower side of the main coupling part  161  may be surrounded by the coupling frame  160 , and a through hole may be formed therein to function as a passage through which the main valve member  331  extends downward. 
     The main coupling part  161  is located on one side of the coupling frame  160  on the cross-section of the coupling frame  160 , such as being located biased toward the rear side in the shown embodiment.

It will be understood that the shape of the main coupling part  161  is the same as the shape of the main support part  151 . 
     The cross-sectional area of the main coupling part  161  may be greater than that of the sub-coupling part  162 . This is due to the difference in the shape and size between the main container  210  and the sub-container  220  as described above.

     A cross-sectional area of the sub-coupling part  162  may be smaller than that of the main coupling part  161 . This is due to the difference in the shape and size between the main container  210  and the sub-container  220  as described above. 
     The sub-coupling part  162  communicates with the sub-support part  152 . A portion of the sub-container  220  may be accommodated in the sub-coupling part  162  after penetrating the sub-support part  152 . In the above embodiment, the shape of the cross section of the sub-coupling part  162  may be formed to be the same as the shape of the cross section of the sub-support part  152 . In addition, in the above embodiment, the sub-coupling part  162  may be disposed to overlap the sub-support part  152  in the up and down direction. 
     A plurality of sub-coupling parts  162  may be formed. As described above, this is because the sub-container  220  and the sub-fluid accommodated therein may be provided in plurality. The plurality of sub-coupling parts  162  may be disposed to be spaced apart from each other. 
     In the shown embodiment, the sub-coupling parts  162  are three, and include the first sub-coupling part  162   a  located on the left, the second sub-coupling part  162   b  located in the central portion, and the third sub-coupling part  162   c  located on the right. Additionally, the first sub-coupling part  162   a,  the second sub-coupling part  162   b,  and the third sub-coupling part  162   c  are disposed adjacent to and along the outer periphery of the cross-section of the coupling frame  160 . The number and arrangement of the sub-coupling parts  162  may be changed according to the number of the sub-containers  220  and the number and arrangement of the sub-support parts  152 . 
     The tray  170  is a space in which a fluid processed according to a control signal inputted by a user is accommodated. A user may obtain a desired effect or efficacy by applying or spraying the fluid accommodated in the tray  170 . 
     The tray  170  is accommodated in the inner space of the housing  100 . Specifically, the tray  170  is accommodated in the lower space of the space of the housing  100 . Accordingly, the tray  170  is located below the fluid receiving part  200  and the conveying part  300 . Accordingly, the fluid on which the processing process has been performed may be accommodated in the tray  170  by dropping by gravity. 
     The tray  170  may be formed to have an extension length in one direction longer than an extension length in another direction. In the shown embodiment, the tray  170  is formed to have an extension length in the front-rear direction longer than the extension length in the left-right direction. 
     The tray  170  is withdrawably accommodated in the inner space of the housing  100 . In other words, the tray  170  is accommodated in the inner space of the housing  100  so as to be slidably movable in the extension direction (front and rear direction in the shown embodiment). In this case, the tray  170  may be retracted in or withdrawn from the inner space through the withdrawal opening  133  formed penetratingly through the front cover  130 . 
     One end of the tray  170  in the extension direction, such as the front end thereof in the shown embodiment, may be exposed to the outside. The one end of the tray  170  may be formed to be rounded so as to be convex outward. In an embodiment, the one end of the tray  170  may be formed in a curved surface having the same curvature as that of the front cover  130 . 
     One side of the tray  170 , such as the upper side in the shown embodiment, may be formed to be open. The fluid that has undergone the processing process may fall and be collected into the fall space  171  formed inside the tray  170  through the open upper side. 
     The inner side of the tray  170 , such as the rear side in the shown embodiment, may be coupled to the rear cover  140 . In this regard, arbitrary withdrawal of the tray  170  can be prevented by a locking device  172  provided between the rear side of the tray  170  and the rear cover  140 . 
     The other side of the tray  170 , such as the lower side thereof in the shown embodiment, may be in contact with the temperature control member  440  of the current carrying part  400 . Accordingly, the fluid accommodated in the tray  170  may be heated or cooled, and thus its temperature may be adjusted. 
     The tray  170  may be supported by the guide frame  180 . The tray  170  may be inserted into or withdrawn from the space formed inside the guide frame  180 . In other words, the tray  170  is slidably accommodated in the space of the guide frame  180 . 
     The tray  170  may be formed of a material having high thermal conductivity. This is for the accommodated fluid to be easily heated or cooled by the temperature control member  440 . 
     The tray  170  may be formed of a material that is easy to clean. This is to prevent the fluid that has been accommodated in the tray  170  from remaining arbitrarily and mixed with or contaminating the fluid introduced next time. 
     In one embodiment, the tray  170  may be formed of a stainless steel material. 
     In the shown embodiment, the tray  170  includes the fall space  171  and the locking device  172 . 
     The fall space  171  is a space in which the fluid that has been subjected to the processing process falls, collected and accommodated. One side of the drop space  171  facing the fluid receiving part  200  and the conveying part  300 , such as the upper side thereof in the shown embodiment, is formed to be open. As described above, since the tray  170  is located below the fluid receiving part  200  and the conveying part  300 , the fluid on which the processing process has been performed can fall by gravity and enter the fall space  171 . 
     Another side of the falling space  171 , such as the lower side in the shown embodiment, is closed by the lower surface of the tray  170 . At this time, when the temperature control member  440  is in contact with the lower surface of the tray  170 , and heats or cools the tray  170 , the fluid accommodated in the fall space  171  is also heated or cooled to adjust its temperature. 
     In an embodiment, an impregnation member, such as cotton, puff, or the like, may be accommodated in the fall space  171 . In the above embodiment, the processed fluid directly falls on the impregnation member, so that the impregnation member can be rapidly impregnated therewith. 
     The locking device  172  couples or decouples the tray  170  with the housing  100 , specifically the rear cover  140 . By the locking device  172 , the tray  170  inserted into the inner space of the housing  100  may not be arbitrarily withdrawn. 
     The locking device  172  may be coupled to the rear cover  140 . One side of the locking device  172 , such as the rear side thereof in the shown embodiment, may be coupled to the inner surface of the rear cover  140 , such as, the front side surface thereof. Another side of the locking device  172 , such as the front side thereof in the shown embodiment, may be coupled to the rear side of the tray  170 . 
     The locking device  172  may be provided in such a way that the distance between the one side and the other side is decreased when the locking device  172  is pressed once, and that the distance between the one side and the other side is increased when the locking device  172  is pressed again. That is, in the above embodiment, the locking device  172  may be provided in the form of a toggle switch. 
     The locking device  172  may be provided in any form which enables it to regulate the tray  170  such that the tray  170  slides only when an external force is applied thereto. For example, the locking device  172  may be provided in the form of a magnetic switch or the like, which is coupled to the rear side of the tray  170  at its one portion and coupled to the front side of the rear cover  140  at its another portion, and which applies attractive force to both sides. 
     The guide frame  180  accommodates the tray  170  withdrawably. The tray  170  may be moved in its extension direction, such as, the front-rear direction, and may be coupled to the guide frame  180  or withdrawn out from the guide frame  180 . 
     The guide frame  180  is located at the lower side of the inner space of the housing  100 . The guide frame  180  is located below the fluid receiving part  200  and the conveying part  300 . 
     The guide frame  180  extends in one direction, such as in the front-rear direction in the shown embodiment. The extension direction of the guide frame  180  may be the same as the extension direction of the tray  170  and the sliding direction of the tray  170 . 
     A space into which the tray  170  is inserted is formed inside the guide frame  180 . The space may be surrounded by a plurality of frames constituting the guide frame  180 . The tray  170  inserted into the space may be supported by a plurality of the frames. 
     One side of the space of the guide frame  180  facing the fluid receiving part  200  or the conveying part  300 , such as the upper side thereof in the shown embodiment, is formed to be open. The fluid that has been processed can pass through the one side and fall into the space of the guide frame  180 . 
     The one side of the guide frame  180  communicates with the fall space  171  of the tray  170 . The fluid that has undergone the processing process may pass through the one side of the guide frame  180  and enter the fall space  171 . 
     Another side of the space of the guide frame  180  opposite to the fluid receiving part  200  or the conveying part  300 , such as the lower side thereof in the shown embodiment, is formed to be open. The tray  170  accommodated in the space of the guide frame  180  may be in contact with the temperature control member  440  located below the guide frame  180 . Accordingly, the fluid accommodated in the fall space  171  may be heated or cooled by the temperature control member  440  to adjust its temperature. 
     A detailed description of the process will be provided later. 
     (2) Description of the Fluid Receiving Part  200   
     Referring to  FIGS. 4 to 14 , the fluid processing apparatus  10  according to the shown embodiment includes the fluid receiving part  200 . 
     The fluid receiving part  200  receives a fluid which a user intends to subject to the processing. A space is formed inside the fluid receiving part  200  to contain a fluid selected by the user. That is, the fluid receiving part  200  functions as a kind of container. 
     The fluid receiving part  200  is removably coupled to the housing  100 . Specifically, the fluid receiving part  200  is penetratingly coupled to the support frame  150 , is partially accommodated in the coupling frame  160 , and is removably coupled to the housing  100 . 
     The fluid receiving part  200  coupled to the housing  100  may not be exposed to the outside. That is, after the fluid receiving part  200  is coupled to the support frame  150  and the coupling frame  160 , the top cover  110  covers the coupled fluid receiving part  200  and is coupled to the support frame  150 . Accordingly, the fluid receiving part  200  is not arbitrarily exposed to the outside, and contamination caused by the exposure can be prevented. 
     The space of the fluid receiving part  200  may be in communication with the outside or the communication may be blocked. Although no reference numeral is provided, a lid that is removably coupled to the upper side of the fluid receiving part  200  is provided. The user may open or close the space formed inside the fluid receiving part  200  by coupling the lid to the fluid receiving part  200  or removing the lid from the fluid receiving part  200 . 
     The fluid receiving part  200  communicates with the valve member  330  of the conveying part  300 . The fluid accommodated in the fluid receiving part  200  may flow to the valve member  330 . At this time, the fluid can flow only when the fluid processing apparatus  10  is operated, which is achieved by a pump member  310 . 
     The fluid receiving part  200  may be formed of a transparent material. This is to allow a user to easily identify the amount of fluid remaining in the fluid receiving part  200  without opening the fluid receiving part  200 . In one embodiment, the fluid receiving part  200  may be formed of a transparent synthetic resin material. 
     As described above, the top cover  110  covering the fluid receiving part  200  may also be formed of a transparent material. Accordingly, the user can easily recognize the amount of the remaining fluid without separating the top cover  110  or the fluid receiving part  200  from the fluid processing apparatus  10 . 
     In the shown embodiment, the fluid receiving part  200  includes the main container  210  and the sub-container  220 . 
     The main container  210  contains the main fluid. The main container  210  is removably coupled to the housing  100 . The main container  210  coupled to the housing  100  may communicate with the main valve member  331  of the valve member  330 . 
     The main container  210  may be singularly provided. This is because the single main fluid or single kind of main fluid is generally provided considering that the main fluid accommodated in the main container  210  functions as a solvent of the sub-fluid. Alternatively, the main container  210  may be provided plurally. In the above embodiment, the main fluid may be provided in a plurality of kinds. 
     The main container  210  is formed to have a greater volume than the sub-container  220 . This is due to the fact that since the main fluid received in the main container  210  functions as a solvent of the sub-fluid, the amount of the main fluid is generally larger than that of the sub-fluid. In the shown embodiment, the volume of the main container  210  may be formed greater than the sum of the volumes of the plurality of sub-containers  220 . 
     The main container  210  is formed to have a predetermined shape. In the shown embodiment, the main container  210  has the front side which is a flat surface, and the rear side which is a curved surface shape convex outwardly. That is, in the shown embodiment, the shape of the cross-section of the main container  210  is semicircular. 
     The shape of the main container  210  may have any shape which enables it to have a space formed therein, and allows the main fluid to be received in the space. However, the shape of the main container  210  is preferably determined to correspond to the shapes of the main support part  151  of the support frame  150  and the main coupling part  161  of the coupling frame  160 . 
     The main container  210  is coupled to the support frame  150 . Specifically, the main container  210  is removably penetratingly coupled to the main support portion  151  of the support frame  150 . 
     The main container  210  is coupled to the coupling frame  160 . Specifically, the main container  210  is removably accommodated in part in the main coupling part  161  of the coupling frame  160 . In the shown embodiment, the lower portion of the main container  210  is accommodated in the main coupling part  161 . 
     The main container  210  may be located biased toward one side in the horizontal direction. In the shown embodiment, the main container  210  is located biased toward the rear side of the support frame  150  and the coupling frame  160 . At this time, the sub-container  220  is located on the front side of the support frame  150  and the coupling frame ( 160 ), so that it is opposite the main container  210 . The position of the main container  210  may be changed according to the positions of the sub-container  220  and the valve member  330 . 
     The main container  210  communicates with the main valve member  331  of the valve member  330 . At this time, the main valve member  331  is opened only when the main pump member  311  of the pump member  310  is operated, so that the main fluid received in the main container  210  can flow toward the mixing nozzle  340 . A detailed description thereof will be provided later. 
     The sub-container  220  is disposed adjacent to the main container  210 . 
     The sub-container  220  receives the sub-fluid. The sub-container  220  is removably coupled to the housing  100 . The sub-container  220  coupled to the housing  100  may communicate with the sub-valve member  332  of the valve member  330 . 
     A plurality of sub-containers  220  may be provided. The sub-fluids received in the sub-containers  220  may be provided in various types, having different functionalities. In the shown embodiment, the sub-containers  220  are three including the first sub-container  220   a,  the second sub-container  220   b  and the third sub-container  220   c,  but its number may be changed. 
     Different sub-fluids may be received in the plurality of sub-containers  220 . Accordingly, a user may select a sub-fluid having a desired functionality from among the sub-fluids received in the plurality of sub-containers  220 , and mix it with the main fluid, thereby manufacturing a mixed fluid having a desired functionality. 
     The sub-container  220  is formed to have a smaller volume than the main container  210 . This is because the sub-fluid accommodated in the sub-container  220  functions as a solute of the main fluid, and the amount of the sub-fluid is generally less than that of the main fluid. In the shown embodiment, the sum of the volumes of the first sub-container  220   a,  the second sub-container  220   b,  and the third sub-container  220   c  may be smaller than the volume of the main vessel  210 . 
     The sub-container  220  is formed to have a predetermined shape. In the shown embodiment, the sub-container  220  has a circular cross-section and has a cylindrical shape extending in the longitudinal direction, that is, the vertical direction. 
     The shape of the sub-container  220  may have any shape which enables it to have a space formed therein, and allows the sub-fluid to be received in the space. However, it is preferable that the shape of the sub-container  220  is determined to correspond to the shapes of the sub-support part  152  of the support frame  150  and the sub-coupling part  162  of the coupling frame  160 . 
     The sub-container  220  is coupled to the support frame  150 . Specifically, the sub-container  220  is removably penetratingly coupled to the sub-support  152  of the support frame  150 . 
     The sub-container  220  is coupled to the coupling frame  160 . Specifically, the sub-container  220  is removably accommodated in the sub-coupling part  162  of the coupling frame  160 . In the shown embodiment, the lower portion of the sub-container  220  is accommodated in the sub-coupling part  162 . 
     The sub-container  220  may be located biased toward the other side in the horizontal direction. In the shown embodiment, the sub-container  220  is located biased toward the front side of the support frame  150  and the coupling frame  160 . In this case, as described above, the main container  210  is located on the front side opposite to the sub-container  220 . The position of the sub-container  220  may be changed according to the positions of the main container  210  and the valve member  330 . 
     The sub-container  220  communicates with the sub-valve member  332  of the valve member  330 . Specifically, the first sub-container  220   a  located on the left communicates with the first sub-valve member  332   a.  In addition, the second sub-container  220   b  located at the center communicates with the second sub-valve member  332   b,  and the third sub-container  220   c  located on the right side communicates with the third sub-valve member  332   c.    
     At this time, each sub-valve member  332   a,    332   b  or  332   c  is opened only when each sub-pump member  312   a,    312   b  or  312   c  of the pump member  310  is operated, and the sub-fluid received in the inside of each sub-container  220   a,    220   b  or  220   c  may flow toward the mixing nozzle  340 . A detailed description thereof will be provided later.

That is, the conveying part  300  is not exposed to the outside of the housing  100 . 
     The conveying part  300  communicates with the fluid receiving part  200 . The main fluid or sub-fluid received in the fluid receiving part  200  may flow to the transfer part  300 . At this time, as described above, the main fluid or the sub-fluid may flow only when the pump member  310  is operated. 
     The conveying part  300  is electrically connected to the current carrying part  400 . Power required to operate the conveying part  300 , particularly the pump member  310 , may be delivered from the current carrying part  400 .

     The pump member  310  communicates with the valve member  330 . When the pump member  310  is operated according to a control signal inputted by the user, the valve member  330  is opened, so that the main fluid or the sub-fluid received in the fluid receiving part  200  may flow. 
     The pump member  310  communicates with the mixing nozzle  340 . The main fluid or the sub-fluid caused to flow by the conveying force applied by the pump member  310  may flow to the mixing nozzle  340 , and be mixed with each other. 
     The pump member  310  is electrically connected to the temperature control member  440 . Specifically, the pump member  310  may be electrically connected to the inputted PCB  410 , and may be operated according to a control signal applied by a user. In addition, the pump member  310  may be electrically connected to the output PCB  420 , and be receive power required for operation. 
     The pump member  310  is located in a lower space of the inner space of the housing  100 . The pump member  310  is located below the support frame  150  and the coupling frame  160  with the mixing nozzle  340  interposed therebetween. In addition, the pump member  310  is located above the tray  170  with the mixing nozzle  340  interposed therebetween. 
     The pump member  310  may be provided in any shape which enables it to apply a conveying force to the fluid when it is operated according to a control signal. In one embodiment, the pump member  310  may be provided in the form of a motor pump that is rotated by an electrical signal to apply a conveying force to the fluid.

     That is, it will be understood that the pump member  310  may be provided as many as the number of the fluid receiving parts  200  provided. 
     The main pump member  311  communicates with the main container  210  through the main valve member  331 . The first sub-pump member  312   a  communicates with the first sub-container  220   a  through the first sub-valve member  332   a.

At this time, any one or more of the plurality of pump members  310  may be operated according to the inputted control signal. 
     In this case, as the main fluid received in the main container  210  functions as a solvent of the sub-fluid, the main pump member  311  of the plurality of pump members  310  is operated whenever a control signal is input, but the plurality of sub-pump members  312  are preferably operated independently according to the inputted control signal. 
     The pump member  310  is accommodated in the pump housing  320 . 
     The pump housing  320  accommodates the pump member  310  to fix the position of the pump member  310 . The pump housing  320  may be coupled to the housing  100 , specifically, to the coupling frame  160  to attenuate vibrations generated by the operation of the pump member  310 . Accordingly, a coupling state between the pump member  310 , the valve member  330 , the mixing nozzle  340 , and the hose member  350  may be stably maintained. 
     A space is formed inside the pump housing  320 . The pump member  310  may be accommodated in that space. As described above, the plurality of pump members  310  may be provided. Accordingly, the space of the pump housing  320  is also divided into a plurality of regions, and any one of the plurality of pump members  310  may be accommodated in each of the partitioned regions. In the shown embodiment, the space of the pump housing  320  is divided into four regions. 
     The space of the pump housing  320  communicates with the outside. Specifically, the pump member  310  accommodated in the space of the pump housing  320  may communicate with the valve member  330  and the mixing nozzle  340 , respectively. 
     The valve member  330  permits or blocks communication between the fluid receiving part  200  and the pump member  310  depending on whether or not the pump member  310  operates. 
     The valve member  330  communicates with the fluid receiving part  200 . In other words, the valve member  330  is connected to the fluid receiving part  200  to be in fluid communication therewith. In the shown embodiment, the upper side of the valve member  330  is penetratingly coupled to the coupling frame  160  and is connected to the lower side of the fluid receiving part  200  accommodated in the coupling frame  160  to be in fluid communication therewith. 
     The valve member  330  communicates with the pump member  310 . In the shown embodiment, the lower side of the valve member  330  is connected to the pump member  310  through the hose member  350  to be in fluid communication therewith. 
     The valve member  330  is located below the fluid receiving part  200 . Accordingly, when the valve member  330  is opened, the main fluid or the sub-fluid received in the fluid receiving part  200  by the gravity and the conveying force applied by the pump member  310  can easily flow toward the pump member  310 . 
     The valve member  330  may be provided in any form which enables it to permit or block the flow of a fluid. In an embodiment, the valve member  330  may be provided as a check valve. 
     In an embodiment in which the valve member  330  is provided as a check valve, the valve member  330  may limit the direction in which the main fluid or the sub-fluid flows, to one direction in which it flows from the fluid receiving part  200  to the pump member  310 . Accordingly, the reverse flow of the main fluid or the sub-fluid (i.e., the direction from the pump member  310  toward the fluid receiving part  200 ) is prevented, so that the operational reliability of the fluid processing apparatus  10  may be improved. 
     The plurality of valve members  330  may be provided. The plurality of valve members  330  may be connected to the plurality of fluid receiving parts  200  and the pump member  310  to be in fluid communication therewith. 
     In the shown embodiment, the valve member  330  includes the main valve member  331  and the sub-valve member  332 . Also, the sub-valve member  332  includes the first sub-valve member  332   a,  the second sub-valve member  332   b,  and the third sub-valve member  332   c.

     The main valve member  331  is coupled to the main container  210  to be in fluid communication therewith. Specifically, the upper side of the main valve member  331  is accommodated in the main coupling part  161  of the coupling frame  160 , and the remaining part thereof penetrates through the coupling frame  160  and extends downward. 
     The upper portion of the main valve member  331  is coupled to a main extension portion  211  of the main container  210  accommodated in the main coupling part  161  to be in fluid communication therewith (see  FIG. 11 ).

     The main valve member  331  may have a greater volume than the sub-valve member  332 . As described above, this is because the flow amount of the main fluid is greater than the flow amount of the sub-fluid. Accordingly, the main fluid received in the main container  210  can flow smoothly. 
     The sub-valve member  332  connects the sub-container  220  and the sub-pump member  312  in fluid communication therebetween. 
     The sub-valve member  332  is coupled to the sub-container  220  to be in fluid communication therewith. Specifically, the sub-valve member  332  has its upper side accommodated in the sub-coupling part  162  of the coupling frame  160 , and the remaining part thereof penetrates the coupling frame  160  and extends downward. 
     The upper portion of the sub-valve member  332  is coupled to a sub-extension portion  221  of the sub-container  220  accommodated in the sub-coupling part  162  to be in fluid communication therewith (see  FIG. 11 ). In one embodiment, the upper portion of the sub-valve member  332  and the sub-extension portion  221  may be screwed to each other. 
     The sub-valve member  332  may have a smaller volume than the main valve member  331 . This is due to the difference in the flow amount between the main fluid and the sub-fluid as described above. 
     As described above, the plurality of sub-containers  220  may be provided. Accordingly, the plurality of sub-valve members  332  may also be provided, and be connected to each of the plurality of sub-containers  220  to be in fluid communication therewith. 
     In the shown embodiment, the sub-valve member  332  includes the first sub-valve member  332   a  communicating with the first sub-container  220   a;  the second sub-valve member  332   b  communicating with the second sub-container  220   b;  and the third sub-valve member  332   c  communicating with the third sub-container  220   c.    
     Each sub-valve member  332   a,    332   b  or  332   c  is coupled to the coupling frame  160  at different locations therein. Specifically, the first sub-valve member  332   a  is accommodated in and connected to the first sub-coupling part  162   a;  the second sub-valve member  332   b  is accommodated in and connected to the second sub-coupling part  162   b;  and the third sub-valve member  332   c  is accommodated in and connected to the third sub-coupling part  162   c.    
     As described above, the plurality of sub-pump members  312  may also be provided. Accordingly, each of the sub-valve members  332   a,    332   b  and  332   c  is connected to the different sub-pump members  312  to be in fluid communication therewith. 
     Specifically, the first sub-valve member  332   a  communicates with the first sub-pump member  312   a  through the hose member  350 . The second sub-valve member  332   b  communicates with the second sub-pump member  312   b  through the hose member  350 , and the third sub-valve member  332   c  communicates with the third sub-pump member  312   c  through the hose member  350 . 
     The main fluid or sub-fluid introduced into the pump member  310  through the valve member  330  flows toward the mixing nozzle  340 . 
     The mixing nozzle  340  collects the main fluid or the sub-fluid received in the fluid receiving part  200  and mixes them with each other. The fluid resulting from the mixing in the mixing nozzle  340  may fall to the tray  170 . 
     Among the components of the conveying part  300 , the mixing nozzle  340  is located at the lowermost side. In other words, the pump member  310 , pump housing  320 , and valve member  330  of the conveying part  300  are located to face the tray  170  with the mixing nozzle  340  interposed therebetween. 
     The mixing nozzle  340  is connected to the pump member  310  to be in fluid communication therewith. The main fluid or sub-fluid which has passed through the pump member  310  may flow to the mixing nozzle  340 . At this time, as the mixing nozzle  340  is located at the lower side of the pump member  310 , the main fluid or the sub-fluid can flow smoothly to the mixing nozzle  340  by the gravity and the conveying force applied by the pump member  310 . 
     As described above, the plurality of pump members  310  may be provided. The mixing nozzle  340  is connected to each of the plurality of pump members  310  to be in fluid communication therewith. 
     In the shown embodiment, the mixing nozzle  340  includes an inlet  341  and an outlet  342 . 
     The inlet  341  is a portion through which the mixing nozzle  340  is connected to the pump member  310  to be in fluid communication therewith. The main fluid or sub-fluid which has passed through the pump member  310  may flow into the mixing nozzle  340  through the inlet  341 . That is, the inlet  341  functions as a flow path for guiding the main fluid or the sub-fluid to the outlet  342 . 
     The inlet  341  is located on one side facing the pump member  310 , such as on the upper side in the shown embodiment. The inlet  341  is coupled to the lower side of the pump member  310 . 
     As described above, the plurality of pump members  310  may be provided. In addition, in the shown embodiment, the plurality of pump members  310  are arranged side by side in the left and right direction. Accordingly, the inlet  341  also extends in the left and right directions, and is respectively coupled to the lower sides of the plurality of pump members  310 . The inlet  341  preferably extends to overlap the pump members  310  located at both ends of the plurality of pump members  310  in the vertical direction. 
     The shape of the inlet  341  may be changed according to the manner in which the plurality of pump members  310  are arranged. 
     The inlet  341  communicates with the outlet  342 . Specifically, a space in which the main fluid or the sub-fluid flows is formed in the inlet  341 . The space in the inlet  341  communicates with the space formed inside the outlet  342 . Accordingly, the main fluid or the sub-fluid flowing to the inlet  341  can flow into the space formed inside the outlet  342 . 
     The outlet  342  mixes the main fluid or the sub-fluid introduced into the mixing nozzle  340 , and discharges the mixed fluid toward the tray  170 . 
     The outlet  342  extends between the inlet  341  and the tray  170 . In the shown embodiment, the outlet  342  extends in the vertical direction, and its upper end is connected to the lower side of the inlet  341 , and the lower end thereof is located to be spaced apart from the tray  170  by a predetermined distance. 
     The space is formed inside the outlet  342 . One side of the space facing the inlet  341 , such as the upper side in the shown embodiment, communicates with the inner space of the inlet  341 . The other side of the space facing the tray  170 , such as the lower side in the shown embodiment, is formed to be open. 
     In this case, the cross section of the space of the outlet  342  may be formed to become narrower toward the tray  170 , that is, downward. Accordingly, the flow velocity of the main fluid or sub-fluid flowing through the space of the outlet  342  increases toward the tray  170 , so that the flow of the main fluid or sub-fluid may proceed more smoothly. 
     Accordingly, the main fluid or sub-fluid which has flown to the inlet  341  may pass through the space of the outlet  342  and fall to the tray  170 . In this case, the main fluid or the sub-fluid may flow together and be mixed in the space of the outlet  342 . 
     Although not shown, an agitating device for mixing the main fluid or the sub-fluid may be provided in the space of the outlet  342 . The introduced main fluid or sub-fluid may be more efficiently mixed and discharged by the agitating device (not shown).

Specifically, the hose member  350  is coupled to one side of the valve member  330  opposite to the fluid receiving part  200 , such as the lower side thereof in the shown embodiment, and to one side of the pump member  310  toward the mixing nozzle  340 , such as the lower side thereof in the shown embodiment. 
     The hose member  350  may be formed of a flexible material. This is to reliably connect the pump member  310  and the valve member  330  to each other even when the pump member  310  is operated generating vibration. In addition, as the hose member  350  is formed of the above material, the arrangement and design freedom of the pump member  310  and the valve member  330  may be improved. 
     As described above, the plurality of the pump members  310  and the valve members  330  may be provided. Accordingly, a plurality of hose members  350  may also be provided, so that the plurality of pump members  310  and the plurality of valve members  330  may communicate with each other. 
     In the shown embodiment, four hose members  350  are provided. The four hose members  350  connect each pump member  310  and each valve member  330  with each other to be in fluid communication therebetween. 
     Specifically, the hose member  350  communicates with the main pump member  311  and the main valve member  331 . Also, the hose member  350  communicates with each of the sub-pump members  312   a,    312   b,  and  312   c  and each of the sub-pump members  312   a,    312   b,  and  312   c.

     The fluid processing apparatus  10  according to an embodiment of this disclosure may process the main fluid or the sub-fluid into a user&#39;s desired form through the above-described configuration, and provide it to the user. 
     Accordingly, the user can conveniently and hygienically process the fluid without manually processing the fluid in order to generate a desired fluid. 
     Hereinafter, a method of controlling the fluid processing apparatus  10  according to an exemplary embodiment of this disclosure will be described in detail with reference to  FIGS. 15 to 22 . 
     In the shown embodiment, the control method of the fluid processing apparatus  10  includes receiving a fluid in the fluid receiving part  200  (S 100 ), coupling the fluid receiving part  200  to the housing  100  (S 200 ), coupling the fluid receiving part  200  to the conveying part  300  (S 300 ), receiving a control signal in the current carrying part  400  (S 400 ), processing the fluid by operating at least one of the conveying part  300  and the current carrying part  400  according to the inputted control signal (S 500 ), and discharging the treated fluid (S 600 ). 
     Also, although not shown, washing the fluid processing apparatus  10  after the discharging the processed fluid (S 600 ) may be further included. In the additional step, the main fluid received in the main container  210  may be additionally discharged by the conveying part  300  to remove the sub-fluids remaining in the conveying part  300 . In the embodiment in which the additional step is included, since the amount of the sub-fluid remaining in the conveying part  300  is minimized, the mixing ratio between the main fluid and the sub-fluid can be more accurately matched. 
     (1) Description of the Step (S 100 ) in which the Fluid is Received in the Fluid Receiving Part  200   
     This is a step in which the fluid desired by the user is received in the fluid receiving part  200 . The fluid received in the fluid receiving part  200  may be processed in various forms and provided to the user as the fluid processing apparatus  10  is operated. Hereinafter, this step (S 100 ) will be described in detail with reference to  FIG. 17 . 
     First, the main fluid is received in the main container  210  (S 110 ). As described above, the main fluid functions as a solvent of the fluid desired by the user. Accordingly, a greater amount of the main fluid is required compared to the sub-fluid, and for this purpose, the volume of the main container  210  is formed to be greater than that of the sub-container  220  as described above. 
     In addition, since the main fluid functions as a base of the fluid desired by the user, the user will generally select the main fluid first than the sub-fluid. 
     Next, the sub-fluid is received in the sub-container  220  (S 120 ). As described above, the sub-fluid functions as a solute of the fluid desired by the user. In addition, the plurality of sub-containers  220  may be provided to receive different sub-fluids. 
     Accordingly, this step (S 120 ) may include receiving a different sub-fluid in at least one of the respective sub-containers  220   a,    220   b  and  220   c.    
     That is, in the shown embodiment, the present step (S 120 ) may include at least one of receiving the first sub-fluid in the first sub-container  220   a  (S 121 ), receiving the second sub-fluid in the second sub-container  220   b  (S 122 ), and receiving the third sub-fluid in the third sub-container  220   c  (S 123 ). 
     (2) Description of the Step (S 200 ) in which the Fluid Receiving Part  200  is Coupled to the Housing  100   
     It is a step (S 200 ) in which the fluid receiving part  200  in which the fluid is received is coupled to the housing  100 , specifically, to the support frame  150  and the coupling frame  160 . The fluid receiving part  200  may be removably coupled to the support frame  150  and the coupling frame  160 . Hereinafter, this step (S 200 ) will be described in detail with reference to  FIG. 18 . 
     First, the main container  210  is coupled to the housing  100  (S 210 ). At this time, the main container  210  is penetratingly coupled to the main support part  151  of the support frame  150  (S 211 ), and then is partially inserted and coupled to the main coupling part  161  of the coupling frame  160  (S 212 ). 
     In addition, the sub-container  220  is coupled to the housing  100  (S 220 ). At this time, the sub-container  220  is penetratingly coupled to the sub-support part  152  of the support frame  150  (S 221 ), and then is partially inserted and coupled to the sub-coupling part  162  of the coupling frame  160  (S 222 ). 
     As described above, the plurality of sub-containers  220  may be provided. In this case, it will be understood that the plurality of sub-containers  220  are respectively coupled to the plurality of main support parts  151  and sub-support parts  152 . 
     Meanwhile, the order of the step (S 210 ) in which the main container  210  is coupled to the housing  100  and the step (S 220 ) in which the sub-container  220  is coupled to the housing  100  may be changed. That is, after the sub-container  220  is first coupled to the housing  100 , the main container  210  may be coupled to the housing  100 . 
     (3) Description of the Step (S 300 ) in which the Fluid Receiving Part  200  is Coupled to the Conveying Part  300   
     The fluid receiving part  200  coupled to the housing  100  is coupled to the conveying part  300 , and communicates with the conveying part  300  (S 300 ). Hereinafter, this step (S 300 ) will be described in detail with reference to  FIG. 19 . 
     First, the pump member  310  and valve member  330  of the conveying part  300  are coupled to each other to communicate with each other (S 310 ). In this regard, as described above, the plurality of the pump members  310  and the valve members  330  may be provided. 
     Accordingly, the main pump member  311  is coupled to the main valve member  331  to be in fluid communication therewith (S 311 ). Also, the sub-pump member  312  is coupled to the sub-valve member  332  to be in fluid communication therewith (S 312 ). 
     As described above, the plurality of the sub-pump members  312  and the sub-valve members  332  may be provided. Accordingly, this step (S 312 ) may include coupling the plurality of sub-pump members  312  and the plurality of sub-valve members  332  to be in fluid communication therebetween. 
     Next, the fluid receiving part  200  and the valve member  330  are coupled to each other to be in fluid communication therebetween (S 320 ). In this case, the plurality of fluid receiving parts  200  may also be provided. 
     Accordingly, the main container  210  is coupled to the main valve member  331  to be in fluid communication therewith (S 321 ). In addition, the sub-container  220  is coupled to the sub-valve member  332  to be in fluid communication therewith (S 322 ). 
     Accordingly, the fluid receiving part  200  and the conveying part  300  may communicate with each other. 
     Meanwhile, this step (S 320 ) may be performed simultaneously with the step (S 200 ) in which the fluid receiving part  200  is coupled to the housing  100 . That is, as the fluid receiving part  200  is coupled to the housing  100  and partially accommodated in the coupling frame  160 , the lower side of the fluid receiving part  200  may be coupled to the conveying part  300  to be in fluid communication therewith. 
     (4) Description of the Step (S 400 ) in which the Current Carrying Part  400  Receives a Control Signal 
     It is a step (S 400 ) in which the fluid processing apparatus  10  receives power and control signals from an external power source and a user. Hereinafter, this step (S 400 ) will be described in detail with reference to  FIG. 20 . 
     First, the current carrying part  400  is electrically connected to an external power source (not shown) (S 410 ). As described above, the connection may be formed by a conductive wire member or the like. 
     Specifically, the power terminal  430  of the current carrying part  400  is electrically connected to an external power source (not shown) (S 411 ). In the above-described embodiment, the power terminal  430  may be provided in the form of a connector terminal, so that an electrically connected state may be formed by coupling the connector member. 
     Next, the inputted PCB  410  receives a control signal from the user (S 420 ). 
     In this case, the main button  411  receiving a control signal related to the operation of the fluid processing apparatus  10  is first operated to receive the control signal (S 421 ). Next, the sub-button  412  to which a control signal related to the processing method of the fluid is applied is operated to receive the control signal (S 422 ). 
     The applied control signal is transmitted to the conveying part  300  and the current carrying part  400 , and is utilized to process the fluid according to the user&#39;s wishes. 
     (5) Description of the Step (S 500 ) in which at Least One of the Conveying Part  300  and the Current Carrying Part  400  is Operated to Process the Fluid According to the Inputted Control Signal 
     According to the control signal inputted by the user, at least one of the conveying part  300  and the current carrying part  400  is operated to process the fluid (S 500 ). Hereinafter, this step will be described in detail with reference to  FIG. 21 . 
     As described above, the temperature control member  440  of the current carrying part  400  is operated when a user inputs a control signal related to the temperature of the fluid. On the other hand, the conveying part  300  is always operated when the user wants to process the fluid. Accordingly, it will be understood that this step is a step in which the fluid processing apparatus  10  is controlled so that the conveying part  300  is always operated, but the temperature control member  440  of the current carrying part  400  is additionally operated or not operated. 
     First, the step (S 510 ) of mixing the fluid according to the inputted control signal will be described. 
     According to the control signal inputted to the inputted PCB  410 , the main pump member  311  of the conveying part  300  is operated. Accordingly, the main valve member  331  is opened, so that the main container  210  and the main pump member  311  communicate with each other. As a result, the main fluid received in the main container  210  passes through the main pump member  311  and flows toward the mixing nozzle  340  (S 511 ). 
     Further, according to the control signal inputted to the inputted PCB  410 , the sub-pump member  312  of the conveying part  300  is operated. Accordingly, the sub-valve member  332  is opened so that the sub-container  220  and the sub-pump member  312  communicate with each other. As a result, the sub-fluid received in the sub-container  220  also passes through the sub-pump member  312  and flows toward the mixing nozzle  340  (S 512 ). 
     It will be understood that, at this time, the sub-container  220 , the sub-pump member  312 , and the sub-valve member  332  are provided plurally, and that the plurality of sub-pump members  312  may be operated independently of each other according to the inputted control signal. 
     The main fluid and the sub-fluid flowing to the mixing nozzle  340  pass through the mixing nozzle  340 , and are mixed and flow toward the tray  170  (S 513 ). As described above, the mixing nozzle  340  is provided with an agitating member (not shown), so that the mixing of the main fluid and the sub-fluid can be proceeded more efficiently. 
     As described above, the fluid processing apparatus  10  according to an embodiment of this disclosure may process any one or more of the main fluid and the sub-fluid, and discharge the processed fluid. Accordingly, it will be understood that any one of the above-described steps may be omitted or the order thereof may be changed. 
     Next, a step (S 520 ) of adjusting the temperature of the fluid according to the inputted control signal will be described. This step (S 520 ) relates to an embodiment in which the main fluid or the sub-fluid is discharged alone, and the temperature thereof is controlled. 
     According to the control signal inputted to the inputted PCB  410 , at least one of the main pump member  311  and the sub-pump member  312  is operated. Accordingly, at least one of the main fluid and the sub-fluid received in the fluid receiving part  200  communicating with the operated pump member  310  flows toward the mixing nozzle  340  (S 521 ). 
     At least one of the main fluid and the sub-fluid flowing toward the mixing nozzle  340  is mixed with each other when passing through the mixing nozzle  340 . The mixed fluid flows toward the tray  170  (S 522 ). 
     According to the control signal inputted to the inputted PCB  410 , the temperature control member  440  is operated (S 523 ). At this time, the temperature control member  440  may be in contact with the tray  170  to heat or cool the fluid received in the fall space  171  of the tray  170 , that is, any one or more of the main fluid and the sub-fluid (S 524 ). 
     Next, a step (S 530 ) of mixing the fluid and adjusting the temperature of the mixed fluid according to the inputted control signal will be described. 
     According to the control signal inputted to the inputted PCB  410 , the main pump member  311  of the conveying part  300  is operated. Accordingly, the main valve member  331  is opened, so that the main container  210  and the main pump member  311  communicate with each other. As a result, the main fluid received in the main container  210  passes through the main pump member  311  and flows toward the mixing nozzle  340  (S 531 ). 
     Further, according to the control signal inputted to the inputted PCB  410 , the sub-pump member  312  of the conveying part  300  is operated. Accordingly, the sub-valve member  332  is opened so that the sub-container  220  and the sub-pump member  312  communicate with each other. As a result, the sub-fluid received in the sub-container  220  also passes through the sub-pump member  312  and flows toward the mixing nozzle  340  (S 532 ). 
     The main fluid and the sub-fluid flowing to the mixing nozzle  340  pass through the mixing nozzle  340 , and are mixed and flow toward the tray  170  (S 533 ). As described above, the mixing nozzle  340  is provided with an agitating member (not shown), so that the mixing of the main fluid and the sub-fluid can be proceeded more efficiently. 
     According to the control signal inputted to the inputted PCB  410 , the temperature control member  440  is operated (S 534 ). At this time, the temperature control member  440  is in contact with the tray  170 , the fluid received in the fall space  171  of the tray  170 , that is, the mixed fluid may be heated or cooled (S 535 ). 
     Although not shown, a process in which the main pump member  311  is operated and a certain amount of the main fluid flows may be added to any one or more of the steps before and after the step S 500 . 
     That is, as this step S 500  is performed, there is a concern that a portion of the main fluid or sub-fluid flowing along the conveying part  300  may remain in the conveying part  300 . In particular, when the main fluid or the sub-fluid remains in the mixing nozzle  340  in which the main fluid and the sub-fluid are mixed with each other, it is difficult to mix fluids according to amounts desired by the user. 
     Therefore, by performing the above step of additionally flowing the main fluid before and after the fluid processing process, it is possible to prevent the main fluid or the sub-fluid from being remained in the conveying part  300 . 
     (6) Description of the Step (S 600 ) in which the Processed Fluid is Discharged 
     According to the control signal inputted by the user, the mixed or heated fluid is discharged to the outside of the fluid processing apparatus  10  and provided to the user (S 610 ). Hereinafter, this step will be described in detail with reference to  FIG. 22 . 
     Through the above-described process, the processed fluid is collected or received in the fall space  171  of the tray  170 . That is, the fluid received in the fall space  171  is in a state of being mixed, and heated or cooled according to the user&#39;s selection. 
     First, the tray  170  is withdrawn from the inner space of the housing  100  (S 610 ). The process may be performed by the user pressing or, conversely, pulling the tray  170  with an external force. By the process, the fall space  171  of the tray  170  and the fluid received in the fall space  171  are exposed to the outside. 
     Next, the fluid received in the fall space  171  of the tray  170  is absorbed by an external matter (S 620 ). The user may scatter or apply the absorbed fluid on his or her skin by pressing the external matter. 
     In this case, the external matter may be provided in any form, such as a sponge, puff, cotton, or the like, which enables it to absorb the fluid, and discharge the absorbed fluid by being pressed. 
     In the above description, it was assumed that a separate impregnation member, such as cotton, puff or the like, is not provided in the tray  170 , but alternatively, the impregnation member may be previously provided in the fall space  171  of the tray  170 . In the above embodiment, it will be understood that step S 620  may be performed at step S 500 . 
     While the preferred embodiments of this disclosure have been referred to and described above, those of ordinary skill in the art can appreciate that it will be understood that various modifications and variations of this disclosure can be made without departing from the spirit and scope of this disclosure as set forth in the claims below.
