Next, with reference to Fig. 10, the ease of use in a state where the water supply tank 400 is set in the refrigerating chamber 400 will be described in detail. Here, FIG. 10 is an operation flow chart for explaining a water supply operation to the water supply tank.

First, the refrigerator 1, which is called a double door type according to the present embodiment, is a layout configuration of a storage room of a standard style in other foreign countries. Therefore, in setting the capacity of the water supply tank 400, it is necessary to take account of consumption amounts of other foreign countries. For example, when the UAE in Saudi Arabia or Saudi Arabia in the Ryukyu region surveyed, the number of samples per 100 households consumed cold water was 10 times a day, The maximum daily consumption is 2L. In addition, the frequency of use of ice is 11 to 12 times a day maximum, and when it is 100 cc at a time, the consumption amount of 1.1 L to 1.2 L is maximum at one day.

Therefore, in this embodiment, the capacity of the water supply tank 400 is set to 3.5L to 4L by adding a plus amount of alpha to the total consumption amount of 3.2L of the cold water and the ice making. In this embodiment, the capacity of the ice storage portion is set to 1.7 L in consideration of the frequency of use of water. This capacity can be accommodated even if the amount of water used is increased. With this 4 L water supply tank 400, even if sufficient water capacity is secured, 2 or 3 L of cold water is secured, so that even if the consumption amount of the cold water is slightly increased, it can be coped with.

Although the water supply tank 400 according to the present embodiment is removed from the refrigerating chamber 210 to supply water from the water supply or to enable internal cleaning, there is a problem in frequently removing the heavy water supply tank 400 . Therefore, in this embodiment, as shown in Fig. 10, the water supply tank 400 can be supplied in a comfortable position even in a state where the water supply tank 400 is set in the refrigerating chamber 210. [

10, when the refrigerator compartment door 60 is opened, the water supply tank 400 is set on the lower left side of the refrigerating compartment 210, as shown in Fig. The water supply portion 403 closed by the opening / closing cover 402 is exposed to the front portion of the first partition shelf 211. In this state, If the water supply unit 403 is closed, the dust is not mixed into the water supply tank 400 when food is put into and discharged from the first compartment shelf 211. Since the inclined surface 412 provided with the water supply portion 403 is continuous with the first partitioning shelf 211 step by step, it is possible to reduce the possibility that the container containing the food hits the water supply tank 400 to drop the food . In addition, since the first compartment shelf 211 is transparent, the food in the refrigerating compartment 210 can be completely monitored.

On the other hand, when the open / close button 415 provided at the foremost part of the upper surface of the water supply tank 400 is operated from the state shown in (a), as shown in (b) The opening / closing lid 402 can be opened as shown in FIG. 4 (d) so that the opening / closing lid 402 is opened. That is, the opening / closing cover 402 can be easily opened with one-touch.

The opened state of Fig. (D) is a state in which the water supply portion 403 is largely opened, and the opening / closing lid 402 is put in a posture position behind the water supply portion 403, so that the first partition shelf 211 and the water supply portion 403 are clearly separated . In addition, since the front portion of the water supply portion 403 is forwardly moved from the rear, water can be easily supplied with an injection port of a plastic bottle in front of the water supply portion 403 as shown in Fig.

In addition, as shown in Fig. 7C, the water injected from the water supply section 403 is less likely to be repelled by the lower inclined surface 405 toward the user, and further, Is closed by the opening / closing cover (402). Further, since the open / close lid 402 is maintained in the open state during water supply, water can be supplied while keeping the plastic bottle with both hands.

As shown in (f), when the supply of water is completed, the front end of the opening / closing lid 402 is locked by the opening / closing button 415 by the operation of closing the opening / closing lid 402, Closing operation can be performed.

13, the upper drawer 264 according to the present embodiment is disposed adjacent to the lower side of the lateral partition wall 4 and further includes a vegetable compartment 260 (not shown) for securing the door compartment 262 in the front portion thereof. As shown in Fig. In addition, since the refrigerator 1 according to the present embodiment includes the automatic ice maker 300, the ice storage portion 320 and the air outlet 350 are provided in the freezing chamber door 50. As a result, the thickness of the freezing chamber door (50) becomes large, so that the thickness of the refrigerator chamber door (60) is inevitably large. Therefore, in the upper drawer container 264, the length Dl0 from the door surface 9 of the refrigerating chamber door 60 located at the front of the lateral partition wall 4 to the distal end of the upper drawer container 264, There is a problem that the food can not be taken out from the upper draw-out container 264 unless the upper draw-out container 264 is drawn forward beyond the obstacle.

However, in the case of pulling out the upper drawer container 264 forward, there is a problem that the upper drawer vessel 264 can not be held unless it is overlapped with a support rail (not shown) formed on both inner wall surfaces of the vegetable chamber 260 There is a limit to the solution for drawing the upper drawer container 264 forward greatly.

Therefore, in the present embodiment, the opening and closing lid 265 is opened on the front face of the upper draw-out container 264 in accordance with the forward movement of the upper draw-out container 264 and housed below the horizontal partition wall 4 when opened. . That is, in this embodiment, the storage container 271 in which the upper side is opened and the front side is obliquely cut, the opening and closing lid 265, and the opening and closing lid 265 are supported from both sides through the movable guide means 272 And the side plates 273 are formed.

The movable guide means 272 includes upper support protrusions 274a and lower support protrusions 274b formed at the upper and lower ends of both sides of the opening and closing lid 265 and first support rails 275a And a second support rail 275b. The first support rails 275a are grooves formed toward the rear and support the upper support protrusions 274a on both sides to move the upper support protrusions 274a in a substantially horizontal direction. On the other hand, the second support rail 275b is a groove formed in the vertical direction, and supports the lower support protrusion 274b on both sides to move the lower support protrusion 274b in a substantially vertical direction.

As shown in Fig. 13 (a), the opening and closing lid 265 is held in a vertical posture so as to intercept the cut front face portion of the storage container 271 in the stored state. On the other hand, when the upper drawer 264 is pulled out, it is held in a horizontal posture between the horizontal partition wall 4 and the lower drawer 267 as shown in FIG.

Next, the opening and closing operation of the opening / closing lid 265 accompanying the movement of the upper draw-out container 264 will be described in more detail with reference to Fig.

When the storage container 271 is pulled forward through the handle portion 274 from this state, the lower end of the opening / closing lid 265 in the vertical posture is guided by the guide rails (not shown) on the obliquely cut wall surfaces on both sides of the storage container 271 277, respectively. However, the lower end of the opening / closing lid 265 is prevented from moving forward due to the fitting structure of the lower support protrusion 274b and the second support rail 275b, so that the stress acts on the lower support protrusion 274b 2 support rails 275. [0043]

Accordingly, the upper support protrusion 274a moves rearward along the first support rail 275a. This operation moves the storage container 271 forward so that the lower end of the opening and closing lid 265 moves upward on the guide rail 277 and moves upward. As a result, as shown in Fig. As described above, the opening / closing cover 265 is housed in a horizontal posture between the lateral partition wall 4 and the moved storage container 271.

The opening and closing lid 265 supported by the guide rail 277 is also gradually moved along the guide rail 277 by its own weight when the storage container 271 is press- And returns to the original housed state as shown in Fig. 5 (a) as shown in Fig. 5 (c).

FIG. 14 (b) shows a prior art having a storage container 271a with its top opened. According to this conventional technology, since the food container 271a can not carry food into and out of the food container 271a only from the upper side, food and beverage, which is formed between the upper end portion of the front face of the opening portion of the storage container 271a and the lower end portion of the refrigerator door 60 There is a problem that the space D20 becomes narrow.

However, in the present embodiment, since the wall surface of the front portion of the storage container 271 is cut, the upper end of the front portion of the opening portion of the storage container 271 and the lower end portion of the refrigerating chamber door 60 Can be made larger than that of the prior art shown in (b). In addition, in the present embodiment, the opening / closing lid 265 is hidden below the lateral partition wall 4, so that there is no obstacle to the receipt and payment of food.
