In the case of the present embodiment, the filter unit 131 includes a bundle of hollow fibers that filters water and activated carbon that adsorbs impurities contained in the water. Moreover, the filter part 131 can be attached or detached with respect to the connection part 132 by inserting / removing in the front-back direction of the refrigerator 100. As shown in FIG. In addition, after inserting the filter part 131 in the connection part 132, the filter part 131 is rotated with respect to the connection part 132, so that the screw thread provided in the filter part 131 and the screw thread provided in the connection part 132 are changed. The filter part 131 and the connection part 132 can be fixed by meshing.

The housing 105 is a box-like member attached to the plate body 172 in a hanging manner. In the case of this embodiment, the housing 105 has a shape that can surround the filter part 131 and the connection part 132, and the upper part is open. The case 105 prevents the stored material stored in the drawer 170 from directly hitting the filter part 131 and the connecting part 132 when the drawer 170 is taken in and out. In addition, the connection part 132 is attached to the housing 105 via the attachment 133, and the filter part 131 is attached to the connection part 132. The attachment 133 is pivotally supported by the housing 105 so as to be tiltable by the attachment shaft 135. Therefore, the filter part 131 is attached to the housing 105 so as to be tiltable about the attachment shaft 135 together with the attachment 133.

FIG. 5 is a perspective view of the plate body with the lid body removed from above.

As shown in the figure, the working hole 173 is provided in a size that allows the filter part 131 to be inserted therethrough and penetrates through the plate body 172, and passes through the work hole 173 from above the plate body 172 to the connection part 132. The attachment / detachment work for attaching / detaching the filter unit 131 can be performed.

The lid body 104 is fitted into the work hole 173 and is flush with the plate body 172.

FIG. 6 is a perspective view showing the attaching / detaching operation of the filter unit.

As shown in the figure, by lifting the tip of the filter portion 131 upward, the fixture 133 is also lifted by the hinge mechanism of the attachment shaft 135, and the tip of the filter portion 131 protrudes above the plate body 172. Therefore, the filter unit can be easily attached to and detached from the connection unit 132 by inserting and removing the filter unit 131 in the direction of the arrow.

As described above, since the purification device 103 is attached to the plate body 172 in a suspended state, the purification device 103 is arranged without significantly affecting the storage space inside the drawer 170. Further, since the work hole 173 is provided in the plate body 172, the replacement work of the filter unit 131 can be performed from above the plate body 172, and the work can be performed in an easy system. In addition, since the work hole 173 is normally closed by the lid body 104, it is possible to place stored items on the plate body 172 or the lid body 104.

FIG. 7 is a perspective view showing the valve device.

The valve device 142 shown in the figure is a device that controls the flow of water introduced to the inside of the refrigerator 100, and is attached to the outside of the back of the box body 150. In the case of the present embodiment, the valve device 142 is connected to the water supply, and the gate valve 143 that can select whether or not to introduce water from the water supply and distribute the introduced water through a path for cooling or manufacture ice. And a three-way valve 144 that can determine whether or not to circulate through the route. The three-way valve 144 has an electrical component 144a that controls the flow path at the top. In addition, a cover member 148 larger than the projected area of the three-way valve 144 is provided on the upper part of the connection part of the

liquid paths

141 and 147 connected to the lower part of the three-way valve 144. Therefore, even if water leaks at the connection part, the cover member 148 can prevent water from being applied to the electrical component 144a, and can improve safety.

FIG. 8 is a cross-sectional view schematically showing the height relationship between the purification device and the valve device, where (a) is a side view and (b) is a top view.

As shown in FIG. 4A, the height at which the valve device 142 is disposed substantially coincides with the height at which the purification device 103 is disposed. Thereby, even when the filter part 131 is removed from the connection part 132, it is possible to prevent the water remaining in the liquid path 141 from overflowing from the connection part 132. In the case of the present embodiment, as shown in FIG. 5B, the left and right positions of the valve device 142 and the purification device 103 are substantially the same. As a result, the length of the liquid path 141 that traverses the box body 150 can be shortened, and a decrease in the heat insulation performance of the box body 150 can be suppressed.

FIG. 9 is a diagram schematically showing the liquid cooling device.

As shown in the figure, the liquid cooling device 140 includes a tank 145 and an ice making machine 146.

Water supplied from the water supply W is supplied to the purification device 103 located inside the refrigerator 100 via a gate valve 143 located outside the refrigerator 100. The water purified by the purification device 103 is led out of the refrigerator 100 and supplied to the three-way valve 144. The water whose path is selected by the three-way valve 144 passes through the liquid path 141 and is supplied to the ice making machine 146, for example. The ice making machine 146 is a device that converts the water purified by the purification device 103 into ice and stores it. The stored ice can be arbitrarily taken out from the supply port 123. On the other hand, the water passes through the liquid path 147 and is supplied to the tank 145. The tank 145 is a member that stores the water purified by the purification device 103. The stored water can be arbitrarily taken out from the supply port 123.

FIG. 10 is a perspective view showing the tank by taking out the drawer.

As shown in the figure, the tank 145 is a meandering thin container, and is disposed behind the drawer 170 and inside the box body 150. By disposing the tank 145 at the position, the cold air flowing while avoiding the drawer 170 directly hits the tank 145, so that the water stored therein can be efficiently cooled. Further, since the tank 145 can be made thinner than the purification device 103, it does not greatly affect the volume of the storage space. The reason why the tank 145 meanders is to suppress the stagnation of water and sequentially supply cooled water.

As shown in the figure, the liquid path 141 connected from the tank 145 to the ice making machine 146 and the supply port 123 is selected from a short path to the outside from the inside of the box body 150 and passes through the outside of the refrigerator 100. The second door 121 is preferably inserted through the hinge. By doing in this way, it becomes possible to avoid as much as possible that water freezes without the liquid path | route 141 and clogs the liquid path | route 141. FIG.

As shown in FIG. 11, the tank 145 may be disposed at the bottom of the first box 151 and below the drawer 170. This further increases the depth of the drawer 170 and increases the storage space.

FIG. 12 is a plan view of the lower part of the first door viewed from the box body side.

As shown in the figure, the purification device 103 is attached to the lower part of the first door 111. Further, the purification device 103 may be covered with the housing 105. According to this, it is possible to easily replace the filter unit 131 in an easy posture without opening the drawer 170.

The present invention can be applied to a refrigerator, particularly a refrigerator that supplies ice or cold water, and includes a plate that partitions the storage space in the vertical direction.
