     DETAILED DESCRIPTION OF THE EMBODIMENTS 
     The exemplary embodiments of the present disclosure will be described in detail below with reference to examples thereof as illustrated in the accompanying drawings, throughout which same or similar elements, or elements having same or similar functions, are denoted here by same or similar reference numerals. The exemplary embodiments described below with reference to the drawings are illustrative only, and are intended to explain, rather than limiting, the present disclosure. 
     In connection with  FIG.  1    to  FIG.  7   , a panel assembly  100  according to an embodiment of the present disclosure includes a panel  11 , a pressing member  12 , and a display box  13 . The panel  11  provides an exterior surface of a device. The pressing member  12  is disposed on the panel  11 . A corresponding functional component in the display box  13  can be activated by a button  122  on the pressing member  12 . The panel assembly  100  of the present disclosure can be applicable in a device, such as a refrigerator, a microwave oven, or a rice cooker, especially, an air conditioner. 
     In some embodiments, as illustrated in  FIG.  3    and  FIG.  6   , the panel  11  has a fitting hole  101 . The pressing member  12  is disposed on an inner side of the panel  11 , and includes a plate body  121  and a button  122  disposed on the plate body  121 . The button  122  extends into the fitting hole  101 . The display box  13  is disposed on a back surface of the panel  11  and opposite to the pressing member  12 . A corresponding functional component of the display box  13  may be selected by pressing the button  122 . The plate body  121  is provided with a flow diverting portion  123 . The flow diverting portion  123  is disposed around the button  122  and configured to divert a fluid out of the display box  13 . That is, the flow diverting portion  123  is capable of diverting a fluid entering an interior of the panel  11  to prevent the fluid entering the interior of the panel  11  from damaging the display box  13 , which can effectively improve stability of the display box  13  and avoid damages to the display box  13  due to an ingress of the fluid. 
     With the panel assembly  100  according to certain embodiments of the present disclosure, the flow diverting portion  123  is disposed around the button  122 , and it is thus possible to achieve diversion of the fluid, especially achieve diversion of a fluid between the pressing member  12  and the panel  11 . Since the flow diverting portion  123  is capable of diverting the fluid out of the display box  13 , it is possible to avoid damages to electronic components inside the display box  13  due to the ingress of the flow into the display box  13 , which effectively improves stability and safety of operation of the display box  13  and prolongs a lifespan of the display box  13 . 
     In addition, isolation provided by the plate body  121  can further prevent the fluid between the plate body  121  and the panel  11  from entering an interior of the display box  13 , which effectively improves the safety and stability of the operation of the display box  13 . 
     For example, in a device provided with the panel assembly  100 , when there is a great amount of splattered fluid, attached fluid, or the like on an outer surface of the panel assembly  100 , some fluid may enter the interior of the panel  11  through a gap between the button  122  and an inner peripheral surface of the fitting hole  101 , which would affect stable operation of the display box  13 . Therefore, in the present disclosure, the fluid entering the interior of the panel assembly  100  is diverted by the flow diverting portion  123  to be discharged promptly, which prevents stable operation of the display box  13  and the electronic components in the display box  13  from being affected. 
     In addition, the panel assembly  100  may be applied in an air conditioner, in which case it is likely to form an airflow of mixed hot and cold air at and around the panel assembly  100 , especially when air is discharged through the panel assembly  100 . The airflow of the mixed hot and cold air may lead to condensation of fluid vapor in the hot air, and thus condensed fluid is generated. Similarly, the flow diverting portion  123  in the present disclosure is capable of diverting the condensed fluid away from the display box  13  to avoid damages to the display box  13 . 
     In at least one embodiment, the button  122  may extend out of the fitting hole  101  to facilitate pressing of the button  122 . Further, a surface of the button  122  extending out of the fitting hole  101  may be an arc-shaped surface. For example, a peripheral edge of an end surface of the button  122  may be flush with a peripheral edge of the fitting hole  101 , while a middle part of the end surface of the button  122  bulges. 
     The flow diverting portion  123  in the present disclosure may have many different forms. For example, a sufficiently large gap may be formed between the plate body  121  and the panel  11 . In some embodiments, when a small gap is formed between the plate body  121  and the panel  11 , the fluid between the plate body  121  and the panel  11  may be retained due to adsorption, which would increase the risk of the damage to the display box  13  due to the fluid entering the interior of the panel  11 . For this reason, in the present disclosure, the pressing member  12  may be spaced apart from the panel  11  to form the flow diverting portion  123 , and the fluid trapped between the plate body  121  and the panel  11  due to the adsorption can be reduced by widening the gap. However, since no diversion is provided to a path of the fluid flow, a flow direction of the fluid between the pressing member  12  and the panel  11  is uncontrollable, and other problems are therefore likely to arise to affect stability of the device. The flow diverting portion  123  in the present disclosure may also be in other forms. For example, in the following description, the present disclosure provides a flow diverting portion  123  with a structure which can achieve directed diversion of the fluid. 
     In conjunction with  FIG.  1    to  FIG.  7   , in some embodiments of the present disclosure, the flow diverting portion  123  is disposed on a surface of the plate body  121  facing towards the panel  11 . A groove is defined on the surface of the plate body  121  as the flow diverting portion  123 . In some embodiments, the flow diverting portion  123  is disposed on the surface of the plate body  121  facing towards the panel  11 . The flow diverting portion  123  includes a first flow diverting groove  1231  and a second flow diverting groove  1232 . The first flow diverting groove  1231  is defined around the button  122 . The second flow diverting groove  1232  is in communication with the first flow diverting groove  1231  and extends to an edge of the plate body  121  through the plate body  121 . 
     Since the fluid enters between the panel  11  and the display box  13  through the gap between the button  122  and the inner peripheral surface of the fitting hole  101 , special protection should be provided around the button  122  to facilitate prompt collection and diversion of the fluid entering between the panel  11  and the display box  13 . In some embodiments, in the present disclosure, the first flow diverting groove  1231  is disposed around the button  122 . The fluid entering the interior of the panel  11  through the fitting hole  101  may be collected in the first flow diverting groove  1231 . The fluid in the first flow diverting groove  1231  may subsequently be diverted towards a predetermined position through diversion of the second flow diverting groove  1232  to achieve directional diversion of the fluid entering the interior of the panel  11  and improve performance on fluid diversion. As a result, the safety and stability of the panel assembly  100  can be improved. 
     In some embodiments, as illustrated in  FIG.  6   , the surface of the plate body  121  is partially hollowed out to form the first flow diverting groove  1231  and the second flow diverting groove  1232 . Both the first flow diverting groove  1231  and the second flow diverting groove  1232  are defined on the surface of the plate body  121  facing towards the panel  11 . Therefore, hollowing out the surface of the plate body  121  can not only make it easy to form the flow diverting grooves on the plate body  121 , but also save a material for forming the pressing member  12 , which is energy-saving and environmentally friendly. In addition, collection and diversion of the fluid entering between the panel  11  and the display box  13  can be facilitated to shorten time in which the fluid is kept between the panel  11  and the display box  13 , allowing a risk of damages to the display box  13  to be greatly lowered. 
     In addition, a part around the button  122  is hollowed out to form the first flow diverting groove  1231 , and at the same time, a part of the plate body  121  connected to the button  122  is thinned. In this way, it is possible for the button  122  to deform readily and easily, which can effectively facilitate use of the button  122 . 
     That is, a first groove portion and a second groove portion are formed on the surface of the plate body  121 . The second groove portion is in communication with the first groove portion. The button  122  is disposed on a bottom wall of the first groove portion. Since the first groove portion, which can be easily deformed due to its thinner bottom wall, is disposed on the plate body  121 , when the button  122  is disposed on the bottom wall of the first groove portion, it is possible to promptly enable the bottom wall of the first groove portion to be deformed when the button  122  is pressed by an external force, allowing the button  122  to be pressed easily. Moreover, the bottom wall of the first groove portion may also provide a reset force to the button  122  to improve stability and tactility of the button  122 . 
     The first flow diverting groove  1231  described above is formed between an inner peripheral surface of the first groove portion and an outer peripheral surface of the button  122 , while the second flow diverting groove is formed as the second flow diverting groove  1232  described above. 
     Further, the plate body  121  is attached to an inner surface of the panel  11 . Since both the first flow diverting groove  1231  and the second flow diverting groove  1232  are formed on the plate body  121 , a channel for diversion may be formed between the plate body  121  and the panel  11 . Considering that the plate body  121  is attached to the inner surface of the panel  11 , sealing can be formed between opening edges of the first flow diverting groove  1231  and the second flow diverting groove  1232  and the panel  11  to from a sealing structure between the surface of the plate body  121  and the inner surface of the panel  11 . With the sealing structure formed between the plate body  121  and the panel  11 , the gap between the plate body  121  and the panel  11  can be sealed. In this way, a gap that may exist around the first flow diverting groove  1231  is also sealed. Therefore, the fluid entering the first flow diverting groove  1231  can be easily diverted through the second flow diverting groove  1232  to prevent the fluid entering the first flow diverting groove  1231  from re-entering a space between the panel  11  and the plate body  121 , which effectively improves the performance on the fluid diversion. 
     In at least one embodiment, a number of the button  122  may be changed in accordance with different devices in which the panel assembly  100  is applied and diversified functions of the different devices to facilitate better control of the devices. In some embodiments, one or more fitting holes  101  are defined on the panel  11 . One or more buttons  122  are provided in one-to-one correspondence with the one or more fitting holes  101 . The flow diverting portion  123  is provided for each of the one or more buttons  122  and disposed around each of the one or more buttons  122 . Therefore, requirements of different products and users on operation methods can be satisfied to make it easy to control the device provided with the panel assembly  100 , which improves stability and convenience of the panel assembly  100 . 
     In addition, the expression “the flow diverting portion  123  is provided for each of the one or more buttons  122  and disposed around each of the one or more buttons  122 ” may mean that the flow diverting portion  123  is separately disposed around each of the one or more buttons  122 . That is, the flow diverting portions  123  and the buttons  122  are in one-to-one correspondence. The flow diverting portion  123  may be in other forms. For example, a common flow diverting portion  123  may be provided. That is, one flow diverting portion 123  may be provided around a plurality of buttons  122 . In this way, the fluid at the plurality of buttons  122  can be collected and subsequently diverted and discharged totally. 
     In at least one embodiment, the pressing member  12  may be a flexible integrated plate. With such flexible pressing member  12 , sealing performance between the plate body  121  and the panel  11  can be effectively improved to further facilitate diversion of the flow diverting portion  123 . In addition, the flexible plate body  121  can facilitate pressing of the button  122 . In addition, during the pressing, the flexible plate body  121  can provide a suitable feedback force and reset force to facilitate reset of the button  122  and improve pressing experience of the button  122 . 
     In addition, the pressing member  12  may be a separated member. For example, the plate body  121  is a flexible plate, and the button  122  is separated from a body of the pressing member  12 , and is flexible, or the button  122  may be a bump. The button  122  and the plate body  121  may be molded separately and subsequently assembled together; or the plate body  121  and the button  122  may be integrally formed through injection molding after the button  122  is molded. 
     In conjunction with  FIG.  1    to  FIG.  7   , in some embodiments of the present disclosure, the display box  13  has an accommodation groove  103 . The accommodation groove  103  is defined on a surface of the display box  13  facing towards the panel  11 , and the pressing member  12  is embedded in the accommodation groove  103 . With the arrangement of the accommodation groove  103 , stability of engagement between the pressing member  12  and the display box  13  can be improved to facilitate mounting of the pressing member  12  in a corresponding position on the display box  13 , allowing easy mounting to be realized. 
     In some embodiments, an important function of the pressing member  12  in use is to select a corresponding control mode through the button  122 , for such a reason that the display box  13  needs to be engaged with the pressing member  12  precisely. Therefore, with the arrangement of the accommodation groove  103 , precision of the engagement between the pressing member  12  and the display box  13  can be effectively improved to facilitate a prompt and convenient selection of the corresponding function. 
     In some embodiments, as illustrated in  FIG.  3   ,  FIG.  6 , and  7   , one of the plate body  121  and the display box  13  is provided with a positioning post  104 , and the other one of the plate body  121  and the display box  13  is provided with a positioning hole  102 . The positioning post  104  is embedded in the positioning hole  102 . In this way, the precision of the engagement between the pressing member  12  and the display box  13  can be further improved. In addition, the engagement between the positioning post  104  and the positioning hole  102  can not only realize pre-positioning of the plate body  121  and the display box  13 , but also avoid a displacement of the pressing member  12  relative to the display box  13 . As a result, the stability of the panel assembly  100  can be effectively improved. 
     For example, as illustrated in  FIG.  6    and  FIG.  7   , in combination with certain embodiments described above, the accommodation groove  103  is defined on the display box  13 . The positioning post  104  is disposed on an inner bottom surface of the accommodation groove  103 . The positioning hole  102  is defined on the plate body  121 . During mounting, the pressing member  12  is mounted in the accommodation groove  103  and the positioning post  104  is embedded in the positioning hole  102  to realize the pre-positioning of the pressing member  12 . Further, stability of the engagement between the plate body  121  and the display box  13  can be effectively improved. 
     In at least one embodiment, the display box  13  has a display region, and the panel  11  is thinned to form a thinned region at a position directly opposite to the display region. That is, content of the display region of the display box  13  is displayed through the thinned region. By hiding the display box  13  in the interior of the panel  11 , a number of through holes defined in the panel  11  can be reduced to lower a possibility of fluid and other impurities from outside entering the interior of the panel  11  to effectively protect the display box  13 , and the panel assembly  100  also has an aesthetically pleasing appearance. In addition, in the event of damages to the display region from the outside the panel  11 , it is possible to only replace the panel  11  instead of replacing the entire panel assembly  100 . 
     In addition, by providing the thinned region, it can be facilitated that light emitted from the display box  13  can pass through the panel  11  more easily, allowing the content to be displayed to be easily formed on the panel  11 . Correspondingly, the display region of the display box  13  may protrude relative to other positions on the display box  13 , which can facilitate a close arrangement of the display region relative to the thinned region to improve display effect. In some embodiments, a groove structure may be formed on an inner side surface of the panel  11  to form the thinned region. In this way, the display region protruding from the display box  13  can extend into this groove to reduce the spacing between the display region and a surface of the panel  11 , which can improve the display effect. 
     In some embodiments, the panel  11  is provided with a limiting rib. The limiting rib abuts against a side edge of the display box. By providing the limiting rib, the display box  13  can be stably mounted on the panel  11  to improve strength of engagement between the display box  13  and the panel  11 . 
     In some embodiments, as illustrated in  FIG.  1   ,  FIG.  4   , and  FIG.  5   , the limiting rib includes a first rib  111  and a second rib  112 . Both the first rib  111  and the second rib  112  are disposed on the panel  11 . The display box  13  is disposed between the first rib  111  and the second rib  112 . Two sides of the display box  13  in a width direction thereof abut against the first rib  111  and the second rib  112 , respectively. A gap is formed between the display box  13  and at least one of the first rib  111  and the second rib  112 . The flow diverting portion  123  is configured to divert the fluid towards the at least one of the first rib  111  and the second rib  112 . 
     In some embodiments, the first rib  111  and the second rib  112  are located at different positions on the panel  11 . In the present disclosure, the panel  11  may be inclined downwardly. In terms of a horizontal plane, the first rib  111  may be arranged at a lower level than the second rib  112 . Therefore, the flow diverting portion  123  described above may be configured to divert the fluid towards the first rib  111 . For example, the second flow diverting groove  1232  described above may be configured to pass through a lower edge of the plate body  121 . That is, one end of the second flow diverting groove  1232  adjacent to the first rib  111  passes through the plate body  121 . In this case, a gap may be formed between the display box and the first rib  111 , in which case the fluid can be discharged through the gap between the display box and the first rib  111  after diverted by the flow diverting portion  123 . 
     The gap may be formed by providing a supporting rib  113  on the first rib  111 . For example, the first rib  111  has a plurality of supporting ribs  113  arranged at intervals in a length direction thereof (a left-right direction in the drawings), and one side of the display box  13  abuts against the supporting rib  113 , which facilitates a formation of a gap between the display box  13  and a lower supporting rib  113  of the plurality of supporting ribs  113 . 
     In addition, the display box  13  may also be provided with a positioning rib  131  on a side thereof. The positioning rib  131  is inserted into and positioned at the first rib  111 . A notch  105  may be formed on a side of the supporting rib  113  facing towards the second rib  112  to catch the positioning rib  131  in the notch  105 . In some embodiments, the display box  13  has one end snap-fitted with the notch  105  and another end pressed and embedded into the second rib  112  on an inner side of the second rib  112 . Therefore, in order to facilitate embedding of the other end of the display box  13  into the second rib  112  on the inner side of the second rib  112 , the second rib  112  may be configured as an arc form that is gradually inclined away from the first rib  111  in a direction facing away from the back surface of the panel  11 , which can facilitate mounting of the display box  13  and avoid a problem of an insufficient space during the mounting. 
     A plurality of reinforcing rib structures may further be connected between the second rib  112  and the inner side surface of the panel  11 . 
     In at least one embodiment, both ends of the display box  13  in a length direction thereof (the left-right direction in the drawings) are fixedly connected to the panel  11 . The pressing member  12  is fixedly clamped through engagement of display box  13  with the panel  11 . Therefore, the display box  13  can be stably mounted on the panel  11 . In addition, stable mounting of the pressing member  12  can be realized through the engagement between the display box  13  and the panel  11 . Clamping the pressing member  12  can provide the pressing member  12  with a predetermined pressure to effectively improve sealing performance between the pressing member  12  and the panel  11 . 
     For example, a connection sheet  132  is disposed at either end of the display box  13  in the length direction thereof. The connection sheet  132  may have a first connection hole. The panel  11  may have a second connection hole. The first connection hole and the second connection hole may be assembled together by a fastener. 
     In some embodiments, in conjunction with the above embodiments, during the mounting of the display box  13 , the pressing member  12  is pre-positioned into the accommodation groove  103  as described, subsequently the positioning rib  131  on one end of the display box  13  is inserted into and positioned at the notch  105  of the supporting rib  113 , and the other end of the display box  13  is rotated to the inner side of the second rib  112 . In this case, the connection sheets  132  on both ends of the display box  13  in the length direction may correspond to features on the panel  11 , and the first connection hole is opposite to the second connection hole. At this time, the display box  13  is locked to the panel  11  by a fastener such as a screw to complete the mounting of the display box  13 . 
     Such a mounting manner can facilitate convenient and prompt mounting of the display box  13  on the panel  11 . 
     In some embodiments of the present disclosure, as illustrated in  FIG.  6   , the plate body  121  includes a first plate portion  1211 , a second plate portion  1212 , and a connection portion  1213 . The first plate portion  1211 , the connection portion  1213 , and the second plate portion  1212  are connected sequentially in a length direction (the left-right direction in the drawings) of the plate body  121 . The display box  13  has a first recess  1031 , a second recess  1032 , and a communication groove portion  1033 . That is, in combination with the above embodiments, the accommodation groove  103  includes the first recess  1031 , the second recess  1032 , and the communication groove portion  1033 . The first recess  1031 , the communication groove portion, and the second recess  1032  are communicated sequentially in the length direction of the display box  13 . The first plate portion  1211  is embedded in the first recess  1031 . The second plate portion  1212  is embedded in the second recess  1032 . The connection portion  1213  is embedded in the communication groove portion  1033 . Therefore, through engagement between the plate body  121  and the accommodation groove  103 , stable mounting of the pressing member  12  can be realized to improve the stability of the engagement between the pressing member  12  and the display box  13 . 
     In some embodiments, in a width direction (a front-rear direction in the drawings) of the plate body  121 , the connection portion  1213  may be connected to edges of the plate body  121  in the width direction, and the communication groove portion  1033  is also connected to edges of the display box  13  in a width direction (the front-rear direction in the drawings). The plate body  121  is configured as a generally U-shaped structure. The first recess  1031 , the second recess  1032 , and the communication groove portion are also formed into a generally U-shaped structure. The plate body  121  is embedded in the display box  13 . In this way, a position of the plate body  121  is uniquely determined, which facilitates mounting of the pressing member  12 . 
     In some embodiments, the button  122  is disposed on each of the first plate portion  1211  and the second plate portion  1212 . The display region includes a digital display region  133  and a lighting region  134 . The lighting region  134  and the button  122  are opposite to each other in the width direction of the plate body  121  (the front-rear direction in the drawings). The digital display region  133  is located between the first recess  1031  and the second recess  1032  in the length direction of the plate body  121 . A pressing behavior of the button  122  may be displayed by the lighting region  134 . Pressing of the button  122  can be displayed by the lighting region  134  and the digital display region  133 , which makes it easy for a user to intuitively understand a response to the pressing and facilitates control. 
     An air conditioner according to an embodiment of the present disclosure includes a body and the panel assembly  100  as described above. The panel assembly  100  is disposed on the body. The air conditioner of the present disclosure may be a hanging air conditioner, a cabinet air conditioner, a mobile air conditioner, a window air conditioner, or the like. 
     According to the air conditioner of the embodiment of the present disclosure, since the panel assembly  100  as described above is provided, the flow diverting portion  123  disposed around the button  122  can achieve diversion of a fluid, especially a fluid entering between the pressing member  12  and the panel  11 . Since the flow diverting portion  123  is capable of diverting the fluid out of the display box  13 , the fluid can be prevented from entering the display box  13  to avoid damages to the electronic components inside the display box  13 , which effectively improves the stability and safety of operation of the display box  13 , and prolongs the lifespan of the display box  13 . 
     In addition, the panel assembly  100  of the present disclosure is especially suitable for a mobile air conditioner. 
     In some embodiments, a body of the mobile air conditioner has an air duct structure opened at a top thereof. The panel  11  is disposed at the top of the body. The panel  11  has an air outlet directly facing towards the air duct structure. An airflow may be blown out through the air outlet. The panel  11  is inclined downwardly in a direction from rear to front. The fitting hole  101 , the button  122 , and the like are disposed at a front side or a rear side of the air outlet. The flow diverting portion  123  as described above is inclined downwardly to divert a fluid. That is, the second flow diverting groove  1232  extends to a lower edge of the plate body  121  through the plate body  121 . 
     In addition, a flange is disposed around the air outlet defined on the panel  11  of the present disclosure. The flange may extend towards the back surface of the panel  11 . A plurality of snap hooks is arranged at intervals along the flange. The plurality of snap hooks can effectively improve stability of engagement between the panel assembly  100  and the body. 
     The panel assembly  100  of the present disclosure includes the panel  11 , the display box  13 , and the pressing member  12  (e.g., a button of a silicone structure). The panel  11  is thinned at a corresponding display position to form a hidden display arrangement. The display box  13  is controlled by the pressing member  12 . A display light on the display box  13  is displayed through the panel  11 . An icon is silkscreen printed at a position on an outer surface of the panel  11  corresponding to a light hole. For the hidden display arrangement without label, mechanical buttons provide poor sealing performance. In humid weather, or in a special circumstance, e.g., the whole machine is caught in the rain, a display panel gets wet easily. A silicone button scheme can provide better sealing and waterproof performance. In addition, a groove is defined on the pressing member  12  to divert the fluid. The flow diverting portion  123  can divert the fluid away when the fluid flows through a gap between the pressing member  12  and the panel  11  to avoid damages to the display panel caused by an ingress of fluid into the interior of the display box  13 . 
     In some embodiments, as illustrated in  FIG.  8    to  FIG.  10   , the air conditioner is a mobile air conditioner. The panel assembly  100  is disposed at an upper part of the body. The flow diverting portion  123  is configured to divert the fluid out of the display box  13  to drain the fluid inside the panel assembly  100 . The air conditioner further includes a flow guide structure  900 . The flow guide structure  900  is disposed inside the body, and configured to guide the fluid diverted by the flow diverting portion  123  into a predetermined position. It is conceivable that the predetermined position may be a base  820  disposed at a bottom of the mobile air conditioner, or other components in the mobile air conditioner that are capable of receiving the fluid, e.g., an intermediate partition plate  300  disposed in a middle of the body, or a certain component outside the body that receives the fluid, and the present disclosure is not limited thereto. 
     The flow diverting portion  123  is disposed on the plate body  121 , and thus is located inside the panel assembly  100 . As a result, the flow diverting portion  123  can divert the fluid entering the panel assembly  100 . Since the flow diverting portion  123  can divert the fluid out of the display box  13 , damages to the electronic components inside the display box  13  due to an entrance of the fluid into the display box  13  can be avoided to effectively improve stability and safety of operation of the electronic components in the display box  13 , and prolong lifespans of the electronic components in the display box  13 . For example, the ingress of the fluid into the panel assembly  100  due to accidental splashing can be avoided. Moreover, the fluid diverted by the flow diverting portion  123  can be guided into the predetermined position by the flow guide structure  900 , it is thus possible to prevent the fluid diverted by the flow diverting portion  123  from spilling in a use environment and affecting environmental sanitation. For example, the wet and slippery ground resulted from the fluid spilled on the ground can be avoided, which may cause people to fall and get injured. 
     With reference to  FIG.  11    to  FIG.  13   , in some embodiments of the present disclosure, the body is provided with an upper air duct assembly  200 . The upper air duct assembly  200  includes an upper air duct heat exchanger  210 , a scroll housing  220 , and an upper air duct fan  230  disposed in the scroll housing  220 . The upper air duct fan  230  may be a centrifugal fan or a cross-flow fan. The flow guide structure  900  is disposed on the scroll housing  220 . In this way, since the flow guide structure  900  is disposed on the scroll housing  220  of the upper air duct assembly  200 , it is possible to reduce a number of parts in the mobile air conditioner and lower production costs of the mobile air conditioner. Meanwhile, in a cooling mode of the air conditioner, the upper air duct heat exchanger  210  is an evaporator. The evaporator can absorb heat during operation, and has a lower temperature. When indoor air with a high temperature exchanges heat with the evaporator, condensed fluid may be generated. Therefore, the condensed fluid may be generated on a surface of the scroll housing  220  above the upper air duct heat exchanger  210  and an outer wall surface  240  of an air outlet  200   a . With the flow guide structure  900 , the condensed fluid may be guided into the predetermined position simultaneously to avoid damages to the mobile air conditioner caused by the condensed fluid entering the electronic components of the mobile air conditioner. 
     For example, the flow guide structure  900  and the scroll housing  220  are integrally formed, which can save assembly steps of the flow guide structure  900  and the scroll housing  220  and reduce assembly time spent on the mobile air conditioner. 
     With reference to  FIG.  11    and  FIG.  12   , in some embodiments of the present disclosure, the flow guide structure  900  includes a fluid receiving tank  400  and a fluid diverting structure  910 . The fluid receiving tank  400  is defined between the scroll housing  220  and the outer wall surface  240  of the air outlet  200   a  of the upper air duct assembly  200 . The fluid receiving tank  400  extends in a length direction of the air outlet  200   a . The fluid receiving tank  400  is adapted to collect the fluid diverted by the flow diverting portion  123 . The fluid receiving tank  400  is provided with a drainage portion  410  on at least one end thereof. For example, the drainage portion  410  is disposed on one end of the fluid receiving tank  400 , or the drainage portion  410  is disposed on each of ends of the fluid receiving tank  400 . The fluid diverting structure  910  is disposed on a side wall of the scroll housing  220 . The fluid diverting structure  910  has an upper part configured to joint with a corresponding drainage portion  410  and a lower part configured to divert the fluid into the predetermined position. The fluid diverting structure  910  serves to divert the fluid in the fluid receiving tank  400  into the predetermined position. 
     With reference to  FIG.  11    to  FIG.  13   , in some embodiments, the drainage portion  410  is formed as a drainage notch as illustrated in the drawings. The fluid in the fluid receiving tank  400  may be discharged into the fluid diverting structure  910  through the drainage portion  410 . It can be understood that in some embodiments, the drainage portion  410  may be formed as a drainage hole, and the present disclosure is not limited in this regard. 
     With reference to  FIGS.  11  and  12   , in some embodiments of the present disclosure, the scroll housing  220  is provided with a sealing plate  500 . The sealing plate  500  may be disposed above the upper air duct heat exchanger  210  between the upper air duct heat exchanger  210  and the scroll housing  220 . The fluid receiving tank  400  is disposed between the sealing plate  500  and the outer wall surface  240  of the air outlet  200   a  of the upper air duct assembly  200 . The sealing plate  500  is provided with a fluid retaining rib  510 . The fluid retaining rib  510  is disposed on an edge of the sealing plate  500 . The fluid retaining rib extends upwards along a surface of the sealing plate  500 , and protrudes from the surface of the sealing plate  500 , in such a manner that the condensed fluid can be prevented from overflowing other parts of the sealing plate  500 , and can flow to the fluid receiving tank  400 . 
     With reference to  FIG.  10    and  FIG.  12   , in this embodiment, the upper air duct fan  230  is a centrifugal fan, and the fluid receiving tank  400  is disposed in an axial direction of the upper air duct fan  230 . Moreover, in this embodiment, a surface of the sealing plate  500  facing away from the upper air duct fan  230  is located at a higher level than a surface of the sealing plate  500  close to the upper air duct fan  230 . That is, the surface of the sealing plate  500  is inclined towards the upper air duct fan  230 , allowing the fluid receiving tank  400  to be defined between the surface of the sealing plate  500  and the outer wall surface  240  of the air outlet  200   a  of the upper air duct assembly  200 . Therefore, no additional fluid receiving tank  400  is required, which can reduce assembling steps of the mobile air conditioner and improve assembly efficiency. In addition, it is possible to reduce costs. Further, the condensed fluid that may be generated on the surface of the sealing plate  500  above the upper air duct heat exchanger  210  and on the outer wall surface  240  of the air outlet  200   a  can automatically flow into the fluid receiving tank  400 . 
     For example, in examples of  FIG.  11    to  FIG.  13   ,  FIG.  15   , and  FIG.  16   , the sealing plate  500  has one or more flow guide ribs disposed on an upper surface thereof. The one or more flow guide ribs may extend in a length direction of the drainage portion  410 . In this way, the one or more flow guide ribs can guide the condensed fluid generated on the upper surface of the sealing plate  500 , and allow the condensed fluid at different positions to flow to the drainage portion  410  in order. In addition, the one or more flow guide ribs can enhance structural strength of the sealing plate  500 . 
     It should be noted that when a plurality of flow guide ribs is provided, the plurality of flow guide ribs may be arranged at intervals in a width direction of the drainage potion  410  to allow a flow guide channel to be defined between two adjacent flow guide ribs of the plurality of flow guide ribs. The condensed fluid generated on the upper surface of the sealing plate  500  can flow to the drainage portion  410  along the flow guide channels. 
     It is conceivable that in some embodiments, the drainage portions  410  may be disposed at both ends of the fluid receiving tank  400 . Correspondingly, the fluid diverting structures  910  configured to joint with the corresponding drainage portions  410  are disposed on two side walls of the scroll housing  220 , allowing the fluid flowing out of the corresponding drainage portions  410  to be diverted into the predetermined position by the fluid diverting structures  910 . When the drainage portions  410  are disposed at both ends of the fluid receiving tank  400 , it should be considered that the condensed fluid is avoided from dripping on the electrical device to avoid failures thereof. The drainage potion  410  may also be disposed on one end of the fluid receiving tank  400 , in which case one side wall of the scroll housing  220  has the fluid diverting structure  910 . The fluid diverting structure  910  corresponds to the drainage potion  410 . 
     With reference to  FIG.  11    and  FIG.  13   , in some embodiments of the present disclosure, the upper part of the fluid diverting structure  910  is configured as a fluid diverting groove  600 , and the lower part of the fluid diverting structure  910  is configured as a flow diverting rib  700 . The flow diverting rib  700  is inclined relative to a horizontal plane at a predetermined angle, in which case the flow diverting rib  700  may be inclined relative to both the horizontal plane and a vertical plane; or the flow diverting rib  700  is arranged vertically, in which case the fluid may flow in an extending direction of the flow diverting rib  700 . Through diversion of the fluid diverting groove  600  and the flow diverting rib  700 , flooding of the fluid can be avoided to prevent the fluid from flowing onto other parts, which can ensure normal use of the device. 
     It should be noted that in some embodiments of the present disclosure, the fluid diverting structure  910  may be configured entirely as the fluid diverting groove  600 . In some embodiments, the fluid diverting structure  910  is configured entirely as the flow diverting rib  700 . In addition, in some embodiments, the fluid diverting structure  910  may also be configured as a structure including both the fluid diverting groove  600  and the flow diverting rib  700  on a basis of a specific structure of a part for supporting the fluid diverting structure  910 . For example, the upper part of the fluid diverting structure  910  is configured as the flow diverting rib  700 , and the lower part of the fluid diverting structure  910  is configured as the fluid diverting groove  600 , and details thereof will be omitted herein. 
     With reference to  FIG.  11    and  FIG.  13   , in some embodiments of the present disclosure, the fluid diverting structure  910  is configured to include a flow diverting rib  700 . The flow diverting rib  700  includes a first flow diverting segment  701 . The first flow diverting segment  701  extends obliquely towards a predetermined position relative to the horizontal plane. In this way, the fluid can flow along the first flow diverting segment  701  and guided into the predetermined position. 
     For example, when the entire fluid diverting structure  910  is configured as the flow diverting rib  700 , an upper part of the flow diverting rib  700  is adapted to joint with the corresponding drainage portion  410 , and a lower part of the flow diverting rib  700  is adapted to divert the fluid into the predetermined position. In this case, when the entire flow diverting rib  700  is formed as the first flow diverting segment  701 , the first flow diverting segment  701  extends obliquely towards the predetermined position relative to the horizontal plane. Further, the upper part of the first flow diverting segment  701  is adapted to joint with the corresponding drainage portion  410 , and the lower part of the first flow diverting segment  701  is adapted to divert the fluid to the predetermined position. When the entire flow diverting rib  700  includes the first flow diverting segment  701  as well as other flow diverting segments, the lower part of the flow diverting rib  700  may be formed as the first flow diverting segment  701  to divert the fluid into the predetermined position. When the fluid diverting structure  910  is configured to include the fluid diverting groove  600  and the flow diverting rib  700 , the flow diverting rib  700  may include the first flow diverting segment  701 . The first flow diverting segment  701  extends obliquely towards the predetermined position relative to the horizontal plane. For example, an upper end of the first flow diverting segment  701  may be directly or indirectly jointed with the fluid diverting groove  600 , which allows the fluid in the fluid diverting groove  600  to flow into the first flow diverting segment  701 . The other end of the first flow diverting segment  701  extends obliquely downwards relative to the horizontal plane towards the predetermined position, which allows the fluid in the first flow diverting segment  701  to flow to the predetermined position due to gravity. Alternatively, a lower end of the first flow diverting segment  701  may be directly or indirectly jointed with the fluid diverting groove  600 , which allows the fluid flowing through the first flow diverting segment  701  to flow towards the fluid diverting groove  600 . 
     In some embodiments, the predetermined position may be a fluid receiving tray  310  on the intermediate partition plate  300 . It should be understood that the predetermined position is not limited to such an example. For example, the predetermined position may be a fluid collection tank inside the mobile air conditioner. When the fluid collection tank is full of the fluid, the fluid collection tank may be taken out to pour out the fluid. The predetermined position may also be a bucket, a drainage port, or the like outside the mobile air conditioner. The fluid is diverted into the predetermined position by the first flow diverting segment  701  to avoid fluid flow flooding, which prevents the fluid from flowing onto other parts and maintain the normal use of the device. For example, a short circuit caused when the fluid flows onto electronic components of the mobile air conditioner can be avoided. 
     With reference to  FIG.  15    and  FIG.  16   , in some embodiments of the present disclosure, the fluid diverting structure  910  is configured to include the flow diverting rib  700 . The flow diverting rib  700  includes a second flow diverting segment  702  and a third flow diverting segment  703 . The second flow diverting segment  702  extends towards the predetermined position. For example, the second flow diverting segment  702  may extend vertically towards the predetermined position, or extend obliquely towards the predetermined position relative to the horizontal plane. The third flow diverting segment  703  is disposed at an upper end of the second flow diverting segment  702 . The third flow diverting segment  703  extends obliquely towards the second flow diverting segment  702  relative to the horizontal plane to divert the fluid discharged from the drainage portion to the first flow diverting segment  701 . That is, the third flow diverting segment  703  extends towards the second flow diverting segment  702 , and extends obliquely relative to the horizontal plane to divert the fluid to the second flow diverting segment  702 . That is, the third flow diverting segment  703  extends towards the second flow diverting segment  702  from top to bottom, in such a manner that an acute angle is formed between the third flow diverting segment  703  and the horizontal plane. Therefore, the fluid can flow through the third flow diverting segment  703  and the second flow diverting segment  702  sequentially, and subsequently flow into the predetermined position. 
     For example, when the entire fluid diverting structure  910  is configured as the flow diverting rib  700 , the upper part of the flow diverting rib  700  is adapted to joint with the corresponding drainage portion  410 , and the lower part of the flow diverting rib  700  is adapted to divert the fluid into the predetermined position. In this case, the entire flow diverting rib  700  includes the second flow diverting segment  702  and the third flow diverting segment  703 . The second flow diverting segment  702  extends towards the predetermined position. The upper part of the third flow diverting segment  703  is adapted to directly or indirectly joint with the corresponding drainage portion  410 . The third flow diverting segment  703  is disposed at the upper end of the second flow diverting segment  702 , to enable the second flow diverting segment  702  to divert the fluid into the predetermined position. When the fluid diverting structure  910  is configured to include the fluid diverting groove  600  and the flow diverting rib  700 , the flow diverting rib  700  may include the first flow diverting segment  701  and the third flow diverting segment  703 . The fluid diverting groove  600  may be defined at an upper end of the flow diverting rib  700  to achieve jointing between the fluid diverting structure  910  and the drainage portion  410 . In this case, an upper end of the third flow diverting segment  703  is directly or indirectly jointed with the fluid diverting groove  600 , to enable the fluid in the fluid diverting groove  600  to flow to the third flow diverting segment  703 . A lower end of the third flow diverting segment  703  is connected to the second flow diverting segment  702 . The third flow diverting segment  703  extends obliquely towards the second flow diverting segment  702  relative to the horizontal plane to allow the fluid to flow into the predetermined position under diversion of the third flow diverting segment  703  and the second flow diverting segment  702 . 
     With reference to  FIG.  15    and  FIG.  16   , in some embodiments of the present disclosure, the fluid diverting structure  910  is configured to include the flow diverting rib  700 . The flow diverting rib  700  includes the first flow diverting segment  701 , the second flow diverting segment  702 , and the third flow diverting segment  703 . The first flow diverting segment  701  is disposed on a lower side of the second flow diverting segment  702  to divert the fluid flowing through the second flow diverting segment  702  into the predetermined position. The fluid discharged from the drainage portion  410  can flow through the third flow diverting segment  703 , the second flow diverting segment  702 , and the first flow diverting segment  701  sequentially, and finally flow into the predetermined position. In addition, prolonging of a length of the flow diverting rib  700  can be facilitated, and structural strength of the scroll housing  220  can be enhanced. 
     The second flow diverting segment  702  may extend vertically, or extend obliquely relative to the horizontal plane. The first flow diverting segment  701  may be connected to a lower end of the second flow diverting segment  702 . The first flow diverting segment  701  may extend obliquely downwards from the lower end of the second flow diverting segment  702 . Therefore, the upper end of the first flow diverting segment  701  is connected to the lower end of the second flow diverting segment  702 . Alternatively, the upper end of the first flow diverting segment  701  may extend upwards beyond the lower end of the second flow diverting segment  702 , in which case the upper end of the first flow diverting segment  701  is located above the lower end of the second flow diverting segment  702 . 
     For example, in examples of  FIG.  15    and  FIG.  16   , the flow diverting rib  700  includes the first flow diverting segment  701 , the second flow diverting segment  702 , and the third flow diverting segment  703 . The second flow diverting segment  702  extends vertically. The third flow diverting segment  703  is disposed at the upper end of the second flow diverting segment  702 . The third flow diverting segment  703  obliquely extends to the upper end of the second flow diverting segment  702  relative to the horizontal plane from top to bottom. The first flow diverting segment  701  is connected to the lower end of the second flow diverting segment  702 , and extends obliquely relative to the horizontal plane from top to bottom. The upper end of the first flow diverting segment  701  is located above the lower end of the second flow diverting segment  702 . 
     When the flow diverting rib  700  includes the first flow diverting segment  701 , the second flow diverting segment  702 , and the third flow diverting segment  703 , the lower end of the second flow diverting segment  702  may also be connected to the upper end of the first flow diverting segment  701 . 
     With reference to  FIG.  14   , in some embodiments of the present disclosure, the mobile air conditioner further includes a lower air duct assembly  800 . The intermediate partition plate  300  is disposed between the upper air duct assembly  200  and the lower air duct assembly  800 . The lower air duct assembly  800  is disposed below the intermediate partition plate  300  and includes a lower air duct heat exchanger  810 . The intermediate partition plate  300  is configured with the fluid receiving tray  310  for receiving the diverted fluid. A drainage hole  311  is defined in a bottom of the fluid receiving tray  310 . The drainage hole  311  is located above the lower air duct heat exchanger  810 . The flow guide structure  900  is configured to guide the fluid discharged from the flow diverting portion  123  to the intermediate partition plate  300 , thus the fluid diverted by the flow diverting portion  123  can be diverted to the fluid receiving tray  310 . In addition, in the cooling mode of the air conditioner, the lower air duct heat exchanger  810  is a condenser. The condenser dissipates heat during its operation. The condensed fluid from the fluid receiving tank  400  is discharged to the fluid receiving tray  310  under the diversion, and drips on the lower air duct heat exchanger  810  through the drainage hole  311  at the bottom of the fluid receiving tray  310 . Therefore, the condensed fluid can assist the lower air duct heat exchanger  810  in dissipating heat to improve a heat dissipation capacity of the lower air duct heat exchanger  810 , which improves energy efficiency of mobile air conditioners and reduces energy consumption of the mobile air conditioner. Therefore, market competitiveness of the mobile air conditioner can be enhanced. In addition, the heat dissipated by the lower air duct heat exchanger  810  evaporates the condensed fluid to eliminate the condensed fluid. Compared with a method for eliminating the condensed fluid by means of disposing the fluid collection tank or an external drainage pipe in the mobile air conditioner, such a method facilitates use of the mobile air conditioner. 
     It is conceivable that, in some embodiments, the flow guide structure  900  is disposed on an inner side wall of the body. With the flow guide structure  900  disposed on the inner side wall of the body, the fluid from the flow diverting portion can be diverted to the base  820  or other predetermined positions, and details thereof will be omitted herein.
