[0009]

[Problems to be Solved by the Invention] In the storage 10,
Water droplets formed on the surfaces of the duct body 22 and the rear partition plate 40 that define the front passage 24 and the back passage 32 through which the cool air flows drop on the bottom duct body 42. In addition, water droplets attached to the food placed on the shelf net 48, debris of the food itself, and the like may fall onto the bottom duct body 42, and the duct body 42 becomes soiled with time. If left unchecked, it becomes unsanitary, so it was necessary to properly clean the bottom duct body 42 and the bottom of the storage chamber 19 (the inner bottom of the heat insulating box 18).

For this reason, in the storage 10, first, the shelf net 48 and the shelf net 4 located just above the bottom duct body 42 are provided.

Had to clean the bottom.

When the bottom duct body 42 and the bottom of the storage chamber 19 are to be cleaned as described above, the shelf net 4 located at the lowermost stage is to be cleaned.
In addition, there is a problem that it takes a very complicated time and effort to take out the food and foodstuffs, and it takes time. Therefore, if the lowermost shelf net 48 is arranged above the bottom duct body 42 at an interval from which the duct body 42 can be taken out, when cleaning the bottom of the bottom duct body 42 and the storage room 19, the shelf net 48 and the foodstuff are used. It is possible to save the trouble of extracting. However, the bottom shelf network 48
If the distance between the base and the bottom duct body 42 is set to be large,
It is pointed out that the storage space of the foodstuff in the storage room 19 becomes small, and the storage amount of the foodstuff is limited.

[0012] As disclosed in Japanese Utility Model Publication No. 62-21901, grooves are formed on the left and right side walls in the refrigerator in a refrigerator, and a tray is slidably disposed between the two grooves. There is an apparatus in which the tray and the bottom can be cleaned simply by removing the tray. However, in the refrigerator according to this proposal, a groove for supporting the saucer must be formed in the refrigerator separately from the support structure of the shelf net for placing the foodstuffs, and the number of processing steps is increased and the production cost is increased. Is pointed out. In addition, there is also a problem that it is troublesome work to clean dirt attached to a sandwiched portion in the groove.

[0013]

The refrigerant is circulated to the cooler 36 with the heat insulating doors 20 and 20 closed, and the blower fan 38 is operated, so that the air sucked from the rear passage 32 by the blower fan 38 is cooled. After being cooled by contact with 36, the air is blown toward the front passage 24 of the upper heat insulating door 20. This cold air flows down the front passage 24 as shown by the arrow in FIG.
Through the front passage 24 of the lower heat insulating door 20 and further flows into the bottom passage 64. The cool air flowing through the bottom passage 64 is
The cycle of ascending the back passage 32 and returning to the space 28 is repeated. The storage chamber 19 is indirectly cooled by the cool air flowing through the passages 24, 64, and 32, and the storage chamber 19 is cooled.
Can be cooled and stored while maintaining the initial quality.

Here, the water droplets generated on the inner wall of the storage room 19, the water droplets attached to the food material, the fragments of the food material itself, and the like fall, so that the tray 51 and the bottom of the storage room 19 become soiled with time. In this case, as shown in FIG. 3 (the shelf net 48 is omitted), the tray 51 is connected to the second support portions 58 and 5.
By pulling out the tray along the front side 8, only the tray 51 can be taken out of the refrigerator without taking out the shelf net 48 and foodstuffs. Accordingly, the tray 51 can be cleaned in a wide place, and the bottom of the storage chamber 19 can be easily cleaned. That is, at the time of daily cleaning, the tray 51 and the bottom can be easily cleaned in a short time without taking out the shelf net 48 and foodstuffs. The support member 5

The room can be reliably cleaned without any obstacles protruding from the room, and the storage room 19 can be always kept in a sanitary manner. Further, since it is not necessary to perform complicated processing for supporting the tray 51 on the inner wall surface of the heat insulating box 18, the manufacturing cost can be reduced.

FIG. 5 shows a modification of the support means, in which second vertical portions 60, 60 are erected at the left and right ends of a bottom plate 61 sized to be accommodated in the heat insulating box 18. At the same time, a second support portion 58 is formed at the upper end of each second vertical portion 60 so as to extend horizontally in a direction away from the other vertical portion 60. Further, first support portions 52, 52 are formed horizontally at ends of the second support portions 58, 58 separated from each other via first vertical portions 56, 56. The support portions 52, 58 and the vertical portions 56, 60 extend at a predetermined length in the depth direction of the storage chamber 19, as in the above-described embodiment. Then, the supporting body 63 as the supporting means is housed and arranged inside the heat insulating box 18, and the second supporting portions 58, 5
By slidably mounting the tray 51 between the eight, a bottom surface passage 64 is defined by the bottom surface of the tray 51, the second vertical portions 60, 60, and the bottom plate 61. This bottom passage 6
4 communicates with the front passage 24 and the back passage 32 of the lower heat insulating door 20, and can guide the cool air flowing down the front passage 24 to the back passage 32.

In the support 63 according to this modification,
Only the tray 51 can be taken out of the refrigerator without taking out the shelf net 48 placed between the first support parts 52,52. In addition, if the support means is taken out of the refrigerator, no obstacle is left in the refrigerator, so that the cleaning of the refrigerator can be easily performed.
