Reference numeral 21 denotes a partition plate for partitioning the inside of the cold storage main body 20 to the left and right, and a plurality of partition plates are provided in the vertical direction. 22a, 22b are cold and hot storage body 2
An outer door and an inner door that cover the opening of No. 0 are mounted in opposite directions.

Reference numeral 23 denotes a tray housed in the cold storage 20. A partition 24 is formed substantially at the center, and the tray 23 is divided into two housings 23a and 23b.

On both sides of the partition plate 21, shelves 25 are provided, and the bottom of the tray 23 is supported by the shelves 25. Reference numeral 26 denotes a packing fitted to the partition plate. The packing 26 is fitted to the upper end surface 27 and the lower end surface 28 of the partition plate 21, sandwiches the partition portion 24 of the tray 23 to be inserted, and forms the packing 26 and the partition portion 24. It is formed so that there is no gap between them.

For this reason, by inserting the tray 23, two compartments 29 and 30 with almost no air circulation are formed.

As described above, the food can be temporarily stored in a plurality of stages by the plurality of partition plates 21 and the trays 23 in a plurality of stages, so that the food is not bulky and stored, so that the food can be refrigerated or stored evenly. And it is less likely to be damaged.

Heat exchange chambers 31, 32 are formed below the compartments 29, 30. Said compartment 29,3
The heat exchange chambers 31 and 32 are separated from each other by a metal plate 33 having a high thermal conductivity such as stainless steel. The upper surface of the metal plate 33 is formed flat, and both side surfaces are inclined downward and outward. ing.

The inclined surfaces 34 and 35 have a discharge hole 36 and a suction hole 37 formed therein. The discharge holes 36 and the suction holes 37 have the same shape in the compartments 29 and 30.

A radiating blower 47 is arranged on the side of the unit 46. An intake hole 48 and an exhaust hole 49 are formed on the bottom of the machine chamber 43.

The operation of the cold storage constructed as described above will be described below.

The food is put into the refrigerator from the outer door 22a of the cold storage main body 20 installed on the wall of the house or the like by delivery or the like. At this time, the compartment 29 is refrigerated and the compartment 30 is kept warm. In this case, the heat carried by the heat exchange liquid from the heat radiation side of the Peltier element by the driving unit 40 is exchanged with the air circulated to the heat exchange chamber 31 by the internal circulation blower 42 from the suction hole 37 in the heat exchanger 38. Heat is exchanged to cool the compartment 29 and maintain it at a predetermined refrigeration temperature.

The compartment chamber 30 receives the heat carried by the heat exchange liquid from the cooling side of the Peltier element by the drive unit 41 and the heat exchange chamber 32 through the suction hole 37 in the heat exchanger 39 and the internal circulation blower (not shown). Heat is exchanged with the air circulated through the chamber to heat the compartment 30 and maintain it at a predetermined storage temperature.

At this time, in the case of the cooling and heating system in the heat exchange chamber 31, the radiator 44 generates heat, and in the cooling and heating system in the heat exchange chamber 32, the radiator 45 absorbs heat. The heat exchange is performed between the radiator 45 and the radiator 45, and the efficiency of the respective cooling and heating systems is greatly improved.

For this reason, even if the voltage applied to the drive units 40 and 41 is small even in a somewhat overloaded state, the inside of the refrigerator can be maintained at an appropriate temperature, and the power consumption can be reduced.

When the compartments 29 and 30 are both refrigerated compartments by changing the direction of current flow to the drive units 40 and 41, the radiators 44 and 45 both generate heat, so that the interior of the machine compartment 43 has a high temperature. State. However, the heat radiation blower 4
7, the indoor air is taken in from the intake port 48 and the exhaust port 4
The heat exchange efficiency of the radiators 44 and 45 is improved by discharging the heat from the radiator 9.

1 is fitted with a packing 52, and the rotor 51
The packing 52 is configured to be movable when it is rotated about its center point as an axis. At this time, when the partition portion 24 of the tray 23 is inserted, the upper surface of the partition portion 24 comes into contact with the packing 52 of the upper partition plate 21, and the lower surface portion of the partition portion 24 and the packing 52 of the lower partition plate 21 come into contact. Since the partitioning portion 24 moves in the insertion direction by abutting, it can be inserted without applying extra force.

Thus, even if a lot of foods are placed on the tray 23, the whole tray 23 can be easily taken in and out, and the work can be performed quickly and efficiently.

The structure of another embodiment of the tray as shown in FIG. 6 will be described.

Reference numeral 53 denotes a tray, which is provided on the left and right
a, 53b, which partition the storage sections
Is provided. The partition 54 has a plurality of through holes 55 formed therein.

By doing so, it is possible to reduce the heat conduction between the storage section 53a and the storage section 53b along the partition section 54. In particular, if the tray 53 is made of metal (for example, aluminum), it is very effective.

Reference numeral 56 denotes a locking means provided on the outdoor side, which is provided in the lower part of the cold / hot storage main body 1 in the embodiment. Reference numeral 57 denotes a display means provided on the indoor side, and when a food is put into the cold / hot storage main body 1 and locked by the locking means 56, a signal is sent and the display means 57 such as an LED is turned on, Inform the user that the food has been delivered.

This is convenient because it is not necessary to check whether food or the like has arrived without opening the door.
