  In order to put vegetables in and out of the front side space 41f of the lower-stage vegetable container 41 and the upper-stage vegetable container 42, the user pulls the vegetable chamber door 17 to the front side (right direction in FIG. 3). Thereby, the lower vegetable container 41 is pulled out with the vegetable compartment door 17, and the upper vegetable container 42 placed on the lower vegetable container 41 is also pulled out. Since the water supply tank 43 is disposed above the upper shallow bottom vegetable room 42p, the upper vegetable container 42 can be stably pulled out without interfering with the water supply tank 43 when the upper vegetable container 42 is pulled out. Moreover, when returning the upper stage vegetable container 42 with the vegetable compartment door 17, it is the same.

  Moreover, when putting in and taking out vegetables etc. in the back side space 41b of the lower stage vegetable container 41, the upper stage vegetable container 42 is pushed in the back side (paper surface left direction of FIG. 3) in the state which pulled out the lower stage vegetable container 41. Since the water supply tank 43 is disposed above the upper shallow bottom vegetable room 42p, the upper vegetable container 42 does not interfere with the water supply tank 43 when being pushed in, and the upper vegetable container 42 can be stably pushed in.

  Also, if the vegetable compartment door 17 is pulled out, the flange portion 43f of the water supply tank 43 is slid on the rail portion 45r and the second rail portion 46r regardless of the position of the upper-stage vegetable container 42. Thus, the water supply tank 43 can be taken out of the vegetable compartment 31 and returned after water supply. Since the water supply tank 43 is disposed above the upper shallow bottom vegetable room 42p, the water supply tank 43 can be stably taken out without interfering with the upper vegetable container 42 when the water supply tank 43 is taken in and out.

  In the embodiment, in order to introduce the water vapor generated in the water supply tank 43 into the vegetable compartment 31, the water supply tank 43 is provided with the tank opening 43m and arranged in the vegetable compartment 31, but the invention is not limited thereto.

  As explained above, in the refrigerator 1 according to the embodiment, the water vapor generated in the water supply tank 43 is introduced into the vegetable compartment 31. Therefore, since the water vapor increases the humidity of the vegetable compartment 31, the humidity in the vegetable compartment 31 can be maintained even if the stored amount of vegetables is small.

  Further, since the water supply tank 43 is disposed in the vegetable room 31, the water vapor generated from the water supply tank 43 can be put in the vegetable room 31 without providing a pipe for introducing the vegetable room, and the configuration of the refrigerator 1 is simplified. You can

  Further, the water supply tank 43 has a tank opening 43m, and the tank opening 43m is closed by a moisture permeable sheet 43s. Therefore, the water vapor that has passed through the moisture-permeable sheet 43s from the tank opening 43m enters the inside of the vegetable compartment 31, so that it is not necessary to make a large-scale structural change or a fall prevention measure for stored items. In addition, it is easy to prevent excessive humidity and dew condensation easily by the moisture permeable sheet 43s, and adjust the flow rate of water vapor from the tank opening 43m with the moisture permeable sheet 43s, that is, a zone where vegetables are stored (lower vegetables It is possible to control the humidity of the room 41h, the upper shallow bottom vegetable room 42p, and the upper main vegetable room 42q). In addition, since the tank opening 43m is closed by the moisture-permeable sheet 43s, it is possible to prevent dust and dirt on the water from entering the water supply tank 43.

  Moreover, the refrigerator 1 is provided with the support part 45 which supports the water supply tank 43 in the vegetable compartment 31. As shown in FIG. The support portion 45 extends downward from the ceiling of the vegetable compartment 31 to project the partition plate 45b for dividing the storage area 31t of the water supply tank 43 in the upper part of the vegetable compartment, and protrudes from the partition plate 45b toward the accommodation area 31t. A rail portion 45r which abuts and supports the water supply tank 43 so as to be slidably movable, and a partition plate opening 45m which is disposed on the partition plate 45b and which allows water vapor to flow out of the storage area 31t. As a result, the water supply tank 43 can be disposed in the vegetable compartment 31 with a simple structure, and the water vapor coming from the water supply tank 43 can be easily introduced into the vegetable compartment 31 from the partition plate opening 45 m. The humidity of the vegetable compartment 31 can be easily maintained at an appropriate level by adjusting in advance the dimensions, the number, and the like of the partition plate openings 45m based on the capacity of the vegetable compartment 31 and the like.

  In addition, the refrigerator 1 includes a second rail portion 46r that protrudes to the accommodation area 31t side and is in contact with the water supply tank 43 so as to be slidably movable, at a position facing the rail portion 45r on the inner side wall 27i of the vegetable chamber 31. Thereby, the force supported by the support portion 45 can be halved, so that the structure of the support portion 45 can be simplified, and the slide movement of the water supply tank 43 with the rail portion 45r and the second rail portion 46r can be facilitated smoothly. .

  Further, the refrigerator 1 is disposed in the water supply tank 43, and is provided with a pump 56 for delivering water out of the tank, and a motor 57 disposed in the partition plate portion 45b to face the pump 56 and operating the pump 56 by magnetic coupling. Equipped with As a result, the positional relationship between the pump 56 and the motor 57 can be simplified, and positional deviation can be prevented. Further, the pump 56 and the magnet piece of the motor 57 can be magnetically coupled only by setting the water supply tank 43, and water can be taken out of the water supply tank 43.

  Moreover, the chilled chamber 50 which has the width | variety from the left side wall of a refrigerator to the right side wall can be provided by arrange | positioning the water supply tank 43 to the vegetable chamber 31, and the storage amount of the chilled chamber 50 can be increased. Moreover, the chilled chamber 50 can be used without feeling a sense of blockage.

  Further, in the upper vegetable container 42, the height of the upper main vegetable compartment 42q is higher than that of the upper shallow vegetable compartment 42p, so effective use of the space beside the water supply tank in the vegetable compartment 31 is achieved. The upper end 42su of the separate plate portion 42s is higher than the upper end of the side wall portion 42w1 and lower than the upper end of the side wall portion 42w2, and vegetables are easily made between the upper main vegetable room 42q and the upper shallow vegetable room 42p. It can be moved, and moreover, the vegetable room door 17 can be stably pulled out and stored.

  It is not essential to provide the moisture-permeable sheet 43s on the tank lid 43c of the water supply tank 43. In order to prevent dirt and dust attached to vegetables from entering the water supply tank 43 without providing the moisture permeable sheet 43s, for example, a large number of small holes may be formed in the tank lid 43c to provide a tank opening. Also, for example, a labyrinth structure may be provided on the tank lid 43c to pass gas (water vapor) but not to pass an object (trash or dust).

  Moreover, various shapes can be considered as a shape of the partition plate opening 45m. For example, as shown in FIG. 7, the partition plate opening 45m1 may be a partition plate opening 45m1 along the longitudinal direction of the partition plate 45b, whereby the partition plate opening having a simple shape can be obtained.
