CROSS-REFERENCE TO RELATED APPLICATIONS
This application claims the benefit of Korean Patent Application No. 10-2011-0126254, filed on Nov. 29, 2011 in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference.
BACKGROUND
1. Field
Embodiments of the present disclosure relate to a refrigerator having an ice making apparatus and/or a dispenser, and more particularly, to a refrigerator configured to be supplied with water from a water storage vessel that is detachably mounted to the refrigerator instead of receiving water while connected to a faucet from an outside water supply source.
2. Description of the Related Art
A refrigerator is an apparatus provided with a storage compartment therein to store foods and a cool air supply apparatus to generate cool air through a cooling cycle and supply the cool air to the storage compartment to keep food fresh.
The refrigerating compartment as such is in the ever increasing trend of becoming larger in size following the change of lifestyle. As to satisfy the demand of users, an ice making apparatus which generates ice or a dispenser configured in a way that the water and the ice may be withdrawn from an outside the refrigerator are being mounted to the refrigerator.
The refrigerator provided with the ice making apparatus or the dispenser mounted thereto as such is needed with a water supply system configured to supply water to the ice making apparatus or the dispenser, and the water supply system as such, while including a pipe line that is connected to a faucet, is generally configured in a way that the water is directly supplied from an outside water supply source, and the water may be supplied to the ice making apparatus or the dispenser by the water pressure applied from the water supply source from an outside.
Meanwhile, instead of the water being supplied from a water supply source from an outside while being connected to a faucet, a refrigerator may receive water from a water storage vessel that is detachably mounted thereto. An example of the refrigerator as such has been suggested in Korean patent publication No. 10-2010-0033494.
The refrigerator suggested as such includes a water supplying container, a container connecting unit configured to mount the water supplying container, a pump configured to pump the water of the water supplying container, and a second passage configured to connect the water supplying container to the ice making apparatus and the dispenser. In this configuration, the refrigerator supplies water to ice making apparatus or the dispenser as the water is pumped by the pump, when the water supplying container is connected to the container connecting unit.
However, in accordance with the publication above, in a case when the water supplying container is to be mounted to the container connecting unit, a portion of the second passage is needed to be disposed at an inside the water supplying container through the entry of the water supplying container, and thus, the mounting of the water supplying container may not be easily performed.
In addition, since the second passage passes through an injection hole of the water supplying container, the injection of the water to the water supplying container may be difficult in a state when the water supplying container is mounted at the container connecting unit, and thus, in a case when the water is needed to be injected to the water supplying container, the water supplying container is needed to be inconveniently detached from the container connecting unit prior to injecting water.

By referring to FIGS. 1 to 9, the attachment/detachment structure of the bracket unit 60 and the water storage vessel 100 of the refrigerator according to the first embodiment of the present disclosure will be explained hereafter. The bracket unit 60 may include a base part 61 and the pump housing 140. The base part 61 has a shape of a plane panel and coupled to the rear surface 34 while being closely adhered to the door 31. The pump housing 140 is protruded toward a front from the base part 60 to accommodate the pump 80 and the valve 90.
The bracket unit 60 may be provided with a plurality of locking protrusions 65 so that the water storage vessel 100 may be mounted on. The water storage vessel 100 may be provided with a plurality of locking steps 113 with which the plurality of locking protrusions 65 is locked.
The locking protrusions 65 is formed in a way that the distance to the base part 61 becomes closer as the locking protrusions 65 faces from an upper side to a lower side thereof, so that the water storage vessel 100 may be mounted to the bracket unit 60 as the locking steps 113 is inserted between the locking protrusion 65 and the base part 61.
The water storage vessel 100 insertedly coupled by the plurality of locking protrusions 65 and the plurality of locking steps 113 as such is additionally supported by the door guard 33 provided at a lower side thereof so that the water storage vessel 100 may be stably mounted to the bracket unit 60.
Meanwhile, the base part 61 of the bracket unit 60 is provided with a penetrating hole (63 in FIG. 9) formed thereon, and the penetrating hole 63 is configured so that the second passage 150 may penetrate therethrough. In addition, the base part 61 of the bracket unit 60 is provided with a guide part 62 protruded to a front therefrom so that the connecting pipe 130, which will be described later, may be installed at the base part 61 of the bracket unit 60. The guide part 62 is provided with a hollowness part 64 formed thereon, so that the connecting pipe 130 may be fixedly installed to an inside the hollowness part 64.
The connecting pipe 130 is configured to form a portion of the second passage 150 by being connected to one end of the third passage 151, and is fixed by being inserted into the hollowness part 64 of the guide part 62. When the water storage vessel 100 is mounted to the bracket unit 60, the connecting pipe 130 may also be connected to an outside protrusion pipe (114 in FIG. 5) of the water storage vessel 100, which will be described later.
Here, the connecting of the connecting pipe 130 to the outside protrusion pipe 114 represents that the second passage 150 provided at the body 10 and the doors 30 and 31 of the refrigerator 1 is connected to the first passage 160 provided at the water storage vessel 100.
Thus, the water introduced to the connecting pipe 130 through the outside protrusion pipe 114 may flow toward the ice making apparatus 20 or the dispenser 40 through the second passage 150.
A sealing member 70 may be installed around the end portion of the connecting pipe 130 to seal the connecting portion at which the connecting pipe 130 and the outside protrusion unit 114 are in contact to each other. The sealing member 70 may be formed with rubber material.
In addition, the connecting pipe 130 may be provided with sufficient rigidity not to be bent at a time when being connected to the outside protrusion pipe 114. In addition, either one of the connecting pipe 130 or the outside protrusion pipe 114 may be provided with a predetermined diameter so that either one of the connecting pipe 130 or the outside protrusion pipe may be connected to the other while wrapping around the other.
One side of the connecting pipe 130 that is connected to the outside protrusion pipe 114 may be disposed in a vertical direction. In addition, the other side of the connecting pipe 130 that is connected to the third passage 151 may be disposed in a horizontal direction. Thus, the connecting pipe 130 may have a bent shape at about 90 degrees in angle.
Next, as for the description of the water storage vessel 100 that is mounted to the bracket unit 60 as such, the water storage vessel 100 may include a body 110 having a storage space 111 formed at an inside therein to store water and having a general shape of a box, and a water storage vessel cover 118 configured to cover an open upper surface of the body 110.
The water storage vessel cover 118 may be separated from the body 110, and a fastening apparatus 119 may be provided at both sides of the water storage vessel cover 118 so that the water storage vessel cover 118 may be coupled to the body 110. In addition, the water storage vessel cover 118 may be provided with the plurality of locking steps 113, which is previously explained, formed therein, and with an injection hole 112, which is configured to inject water to an inside the water storage vessel 100, formed therein.
Thus, the water storage vessel 100 is provided with a front surface 125, a rear surface 126, a left side surface 127, a right side surface 128, an upper surface 116, and a bottom surface 117, and is provided at the upper surface 116 thereof with the injection hole 112 to inject water to the storage space 111.
In addition, the water storage vessel 100 may include an inside case 122 having a water purifying filter (124 in FIG. 7) installed therein to filter the water injected through the injection hole 112. The inside case 122 may be separated from the body 110, and may divide the storage space 111 into a first storage space 131 and a second storage space 132 while mounted to the body 110.
The inside case 122 is provided with a communication hole 133, which is configured to funnel the first storage space 131 and the second storage space 132, therein, and the water purifying filter 124 may be installed at the communication hole 133. Thus, the water injected to the first storage space 131 may flow to the second storage space 132 after being purified through the water purifying filter 124.
The inside case 122 may be detached from the body 110. Thus, in a case when a cleaning or a replacement of the water purifying filter 124 is needed, the inside case 122 may be detached from the body 110 to either clean or replace the water purifying filter 124 conveniently.
Since the water storage vessel 100 as the above is provided therein with the first storage space 131 and the second storage space 132 that are available to be detached from one another, and the water purifying filter 124 is installed at the communication hole 133 that is configured to communicate the first storage space 131 with the second storage space 132, the water that is not completely purified may be injected to the water storage vessel 100, and using the water as such may be possible.
The water storage vessel 100 as such is provided therein with a first passage 120 to intake the water stored at an inside thereof. The first passage 120 may include the outside protrusion pipe 114 protruded to an outer side from the rear surface 126 of the body 110, an inside protrusion pipe 115 protruded from the rear surface 126 of the body 110 toward an inner side, and an intake passage 154 connected to the inside protrusion pipe 115 and extended to the bottom surface 117 of the body 110.
Here, the outside protrusion pipe 114 and the inside protrusion pipe 115 may be integrally injection-molded with the body 110, using the material that composes the body 110, thereby having predetermined rigidity.
The intake passage 154 may be provided with rigidity or flexibility, and the entry 155 of the intake passage 154 is disposed at the second storage space 132 to intake the water stored at the second storage space 132 of the water storage vessel 100.
Since the outside protrusion pipe 114 and the inside protrusion pipe 115 are provided in a way that the outside protrusion pipe 114 and the inside protrusion pipe 115 communicate with each other, and the inside protrusion pipe 115 is connected to the intake passage 154, the water stored at the water storage vessel 100 sequentially passes through the inside protrusion pipe 115 and the outside protrusion pipe 114 in order, and flows to the connecting pipe 130 that is installed at the bracket unit 60. In addition, one side of the outside protrusion pipe 114 may be extended to a vertical direction to be connected to one side of the connecting pipe 130 that is disposed in a vertical direction.
Meanwhile, a groove unit (129 in FIG. 5) that is recessed inward is formed at the rear surface of the body 110 so as to prevent the water storage vessel 100 from being interfered with the guide part 62 of the bracket unit 60 at the time when the water storage vessel 100 moves in a direction from an upper side to a lower side.
As the above, the injection hole 112 which is configured to inject water to an inside the water storage vessel 100 is formed at the upper surface 116 of the water storage vessel 100, and the outside protrusion pipe 114 and the inside protrusion pipe 115 through which the water inside exits is formed at the rear surface 126 of the water storage vessel 100, and thus, water may be easily injected to the water storage vessel 100 even in a state when the water storage vessel 100 is already mounted to the bracket unit 60. Thus, the water storage vessel 100 is not needed to be detached from the bracket unit 60 in order to inject water to the water storage vessel 100.

FIG. 14 is a block diagram illustrating a water supply distribution of a refrigerator in accordance with a third embodiment of the present disclosure. FIG. 15 is a block diagram illustrating a water supply distribution in a case when water is supplied to an ice making apparatus of the refrigerator of FIG. 14. FIG. 16 is a block diagram illustrating a water supply distribution in a case when water is supplied to a dispenser of the refrigerator of FIG. 14. FIG. 17 is a rear perspective view of a pump housing of the refrigerator of FIG. 14.
As illustrated on FIGS. 14 to 17, a water supply system of a refrigerator, according to the third embodiment of the present disclosure, may be able to selectively supply water to the ice making apparatus 20 and the dispenser 40 by using four check valves 301, 302, 303, and 304 instead of the 3-way valve which is described earlier along with a pump 350 capable of reciprocal rotation.
As illustrated on FIG. 14, a supply passage includes a first sub passage 311 connecting the water storage vessel 100 to the dispenser 40, a second sub passage 312 connecting the water storage vessel 100 to the ice making apparatus 20, and a third sub passage 313 connecting one point 321 of the first sub passage 311 to one point 322 of the second sub passage 312.
The first sub passage 311 and the second sub passage 312 may divide apart at the one point 323 after starting as a single passage from the water storage vessel 100.
At this time, the first check valve 201 and the second check valve 302 are installed to the first sub passage 311 at a front position and a rear position of the one point 321, respectively, to prevent the water flowing backward to the water storage vessel 100. In addition, the third check valve 303 and the fourth check valve 304 are installed to the second sub passage 311 at a front position and a rear position of the one point 322, respectively, to prevent toe water flowing backward to the water storage vessel 100.
In addition, the pump 350, which is capable of rotating clockwise and counterclockwise directions, is installed to the third sub passage 313. The pump 350 is provided with a plurality of entry/exit holes, and each of the entry/exit holes may be connected to the third sub passage 313. In addition, the pump 350 may include an impeller configured to forcedly circulate water and a driving motor configured to rotate the impeller to a clockwise or counterclockwise direction.
Thus, a certain one of the entry/exit holes of the pump 350 is connected to the first check valve 301 and the second check valve 302, and a certain the other one of the entry/exit holes of the pump 350 is connected to the third check valve 303 and the fourth check valve 204.
Each of the check valves 301, 302, 303, and 304 prevents water flowing backward to the water storage vessel 100, and forces the water to flow only to a direction illustrated as an arrow. The dispenser 40 is connected to an exit side of the second check valve 302, and the ice making apparatus 20 is connected to an exit side of the fourth check valve 304.
As illustrated on FIG. 15, when the pump 350 is rotated to a clockwise direction, the water stored in the water storage vessel 100, by the intake force of the pump 350, moves along the direction A illustrated as an arrow, and is supplied to the ice making apparatus 20.
That is, the water stored in the water storage vessel 100, after sequentially passing through the first check valve 301, the pump 350, and the fourth check valve 304, may be supplied to the ice making apparatus 20.
At this time, the water passed through the first check valve 301 flows toward the side of the pump 350 by the intake force of the pump 350, and the water passed through the pump 350, since the water may not pass through the third check valve 303, only flows toward the side of the fourth check valve 304 to be supplied to the ice making apparatus 20.
In addition, as illustrated on FIG. 16, when the pump 350 is rotated to a counterclockwise direction, the water stored in the water storage vessel 100, by the intake force of the pump 350, moves along the direction B illustrated as an arrow, and is supplied to the dispenser 40.
That is, the water stored in the water storage vessel 100, after sequentially passing through the third check valve 303, the pump 350, and the second check valve 302, may be supplied to the dispenser 40.
At this time, the water passed through the fourth check valve 304 flows toward the side of the pump 350 by the intake force of the pump 350, and the water passed through the pump 350, since the water may not pass through the firth check valve 301, only flows toward the side of the second check valve 302 to be supplied to the dispenser 40.
Meanwhile, as illustrated on FIG. 17, the check valves 301, 302, 303, and 304 as well as the pump 350, may be accommodated at the pump housing 140. The pump housing 140 as such is provided at a higher position when compared to the position of the water storage vessel 100, and thus, in a case when the pump 350 is not rotated to any direction, the water stored in the water storage vessel 100 is not supplied to the ice making apparatus 20 or the dispenser 40 and may stay in the water storage vessel 100.
According to an embodiment of the present disclosure as such, the passage conversion may be achieved even if deleting the conventional 3-way valve, thereby reducing the production cost and achieving compact size components.
Although a few embodiments of the present disclosure have been shown and described, it would be appreciated by those skilled in the art that changes may be made in these embodiments without departing from the principles and spirit of the disclosure, the scope of which is defined in the claims and their equivalents.
