Reference numeral 45 denotes a drawer-type door provided at the front opening of the third storage chamber 37 and connected to the lower storage container 42. 46 is the pull-out door 4 of the third storage room 37
5 is a second revolving door provided in the fifth revolving door. 47 is the main body 27
A compressor 48 provided at the bottom of the first storage chamber 35 is a cooler housed on the back of the first storage chamber 35, and constitutes a known refrigeration cycle to which a condenser (not shown) is added. The reference numeral 49 designates the air cooled by the cooler 48 as the first, second and third storage chambers 35 and 3.
It is a blower for forced ventilation in 6,37. 50 is a discharge air passage leading to the first storage room 35, 51 is a discharge air passage leading to the second storage room 36, and 52 is a return air provided on the lower back surface of the first storage room 35 and leading to the cooler 48. A passage 53 is a return air passage that penetrates through the inside of the first partition wall 33 and leads from the second storage room 36 to the cooler 48. Reference numeral 54 denotes a discharge air passage branching from the discharge air passage 51 and leading to the third storage chamber 37, and reference numeral 55 denotes a cooler from the return air passage 53 passing through the second storage chamber 36 through the second partition wall 34.

The operation of the thus configured food storage will be described below. The air cooled by the cooler 48 is circulated by the blower 49, cools the first storage chamber 35 through the discharge air passage 50, and returns to the cooler 48 through the return air passage 52. On the other hand, since the evaporating temperature of the cooler 48 can be set high, the inside of the first storage chamber 35 is maintained at an intermediate temperature, and the dehumidifying action is suppressed to maintain an appropriate humidity (about 30 to 50% RH) that is not excessively dried. Is done. Therefore, the first
Since the storage room 35 is maintained at a constant humidity, it is possible to store various foods in the same place, prevent over-drying of the known refrigerated storage, and store the food in the first storage room 35. Preservability is improved.

For the second storage room 36, a cooler 48
Is cooled by the blower 49 to cool the second storage chamber 36 through the discharge air passage 51. The first damper thermo 56 controls the second storage chamber 36 at a constant temperature. Return air is returned to the cooler 48 through the return air passage 53. Lid 40 of storage container 38 of second storage room 36
Is mainly composed of a moisture-permeable membrane, so that the inside of the storage container 38 can be maintained at a high humidity. As a result, the second storage chamber 36 can be kept at a constant temperature and high humidity, so that drying of the stored food can be suppressed. In addition, since the second storage chamber 36 is kept at a constant temperature, dew condensation in the storage container 38 can be suppressed, and thus the stored food can be stored for a long time. It becomes possible. For the third storage room 37, the cooler 48
The air cooled in the third storage room 3 is discharged through the discharge air passage 54.
Cool 7 The inside of the third storage room 37 is controlled to a medium temperature by the second damper thermo 57. Third storage room 37
Is returned to the cooler 48 via the return air passage 55 and the return air passage 53 of the second storage chamber 36. By setting the medium temperature, it becomes possible to store low-temperature-resistant food. Further, the storage container of the third storage room 37 is composed of an upper storage container 41 and a lower storage container 42, and only the lower storage container 42 is connected to the pull-out door 45. When the door 45 is pulled out, only the lower storage container 42 is pulled out, so that the inside is easy to see,
Storage is convenient. On the other hand, the drawer-type door 45 is provided with a second rotary door 46 so that food (eg, rice) stored therein can be easily taken out without opening the drawer-type door 45.

Further, the deodorizing device 58 can remove food odors filling the first, second, and third storage chambers 35, 36, and 37.

As an embodiment of the present invention as described above, the temperature, humidity, and stored food in each storage room can be shown in (Table 1).

[0019]

[Table 1]

[0020]

As described above, the food storage of the present invention has the following effects.

(1) Since the inside of the storage room can be maintained without being excessively dried, drying of the food is suppressed, and the food can be stored freshly.

(2) The lid of the storage container in the second storage chamber is made of a moisture permeable membrane, and can be kept at a constant temperature and high humidity by an independent discharge air path and a control device, and can be dried. This makes it possible to maintain good storage conditions of, for example, livestock meat, processed marine products, chilled dairy products, etc., which are liable to deteriorate in quality, and to suppress dew condensation in the storage container by maintaining a constant temperature.

(3) In the third storage room, the temperature inside the storage container can be maintained at an intermediate temperature by an independent discharge air passage and a control device. It becomes possible to save.

(4) In the third storage room, the stored food can be properly used by the upper and lower two storage containers, and the drawer type door of the entire storage room can be opened and closed by the second rotary door. It is possible to easily take out the stored food without the need, and the storage property and usability are improved.

(5) By attaching the deodorizing device to the return air passage, the food odor filling the food storage can be removed, so that the odor transfer between foods is suppressed,
It becomes possible to prevent the odor of the food from changing during the storage period.
