Abstract

PURPOSE:To prevent a decrease of an efficiency of the heat exchange in a condenser, by preventing a short cycle with a high temperature air, through forming a partition between a main body and a floor face, so as to ensure an air duct between a back face of the main body and a wall. CONSTITUTION:A refrigerating cycle is executed by a refrigerating unit 9 set in a machine room 8 at an under section of a body 1, in a cooling storage shed, and an inside of the storage shed is refrigerated by a heat exchange against a coolant at an evaporator 13 set at the inside of the storage shed. An outside air sucked from a front face side of the body, at this time, executes a heat exchange at a condenser 10. The air having had a high temperature is sent to a compressor 12 at the leeward side, by a blower 11 for suction. After it takes a heat of the compressor 12, it is discharged to an air duct 17 for an exhaust between a back face of the body and an inside wall of a room which is ensured by projections 16A, 16B set at lower sections of the back face of the main body 1. On the other hand, the air having the high temperature and being exhausted to a space of leg sections 14 at a low face of the main body 1, is cut out by a partition plate 19 set at a lower section of the main body 1, flows reversely after being stooped, and it is to be exhausted to the back face of the main body 1.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cold storage such as a refrigerator or a showcase.

[0002]

2. Description of the Related Art In recent years, in order to improve heat exchange in a cooling storage, a forced ventilation type fin-and-tube type condenser is used.

Hereinafter, the conventional cooling storage cabinet will be described with reference to the drawings. FIG. 5 is a sectional view of a conventional cooling storage. In FIG. 5, reference numeral 1 is a main body of a storage, and the main body 1 is composed of an outer box 2, an inner box 3 and a heat insulating material 4, and a front surface of the main body 1 has an opening 5 for storing and taking out food and the like. In addition, an opening type heat insulating door 6 that can be opened and closed is provided in the opening 5.

A plurality of rulers are provided on the front surface of the lower portion of the main body 1.
A front cover 7 having a bar opening is provided, and a machine room 8 for a refrigerating machine is formed inside. The refrigerating device 9 provided in the machine room 8 is provided with a condenser 10 on the front cover 7 side,
A forced-ventilation blower 11 is provided behind the blower 11. Further, a compressor 12 is provided behind it. The back surface of the machine room 8 is open. An evaporator 13 is provided inside the main body 1 of the storage.

The compressor 12, the condenser 10 and the evaporator 13 are connected by piping including a throttle device (not shown). Also, on the bottom surface of the main body 1, four legs 14 that support the main body 1 are provided.
Is provided.

The operation of the cooling storehouse constructed as described above will be described below.

First, a freezing cycle is performed by a refrigerating device 9 provided in a machine room 8 below the main body 1, and heat is exchanged by an evaporator 13 provided inside the refrigerator to cool the inside of the refrigerator. On the other hand, the high temperature outside air that has undergone heat exchange in the condenser 10 is sucked in from the front side of the main body 1 by the blower 11 for suction, is blown to the compressor 12 on the leeward side, and is further exhausted to the outside of the rear side of the main body 1.

[0008]

However, in the above-mentioned conventional structure, when the main body is installed in a place where there are walls on both sides and the back side and the three sides are surrounded, the blower 11 for the condenser sucks in from the front side. The outside air is heat-exchanged in the condenser to become high temperature air, which is exhausted from the rear surface of the machine room 8 to the lower surface of the main body, and the high temperature outside air returns to the front surface side again to cause a short cycle, which causes heat of the condenser. There was a drawback that the exchange efficiency was lowered.

The present invention solves the conventional problems.
An air passage is secured between the back of the main unit and the wall, and a partition is provided between the main unit and the floor to prevent a short cycle due to high temperature air and to reduce the heat exchange efficiency of the condenser. It is an object.

[0010]

In order to achieve this object, the cooling storage of the present invention comprises a convex portion provided on the lower portion of the back surface of the main body, and left and right band-shaped partition plates provided on the lower surface of the main body. .

[0011]

In the cooling storage of the present invention, the air passage is secured between the back surface of the main body and the wall, and the air sucked from the front surface can be discharged upward from the back surface of the main body in one direction.

Further, since the partition plate is configured to control the gap in the air passage due to the temperature difference of the exhaust heat, it is possible to enhance the heat exchange efficiency of the condenser by repeating the short cycle at a low temperature. it can.

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

First, a freezing cycle is performed by a refrigerating device 9 provided in a machine room 8 below the main body 1, and heat is exchanged by an evaporator 13 provided inside the refrigerator to cool the inside of the refrigerator. On the other hand, the outside air sucked from the front side of the main body 1 is shielded by the shield plates 15A, 15A.
At B, the heat is exchanged in the condenser 10 and becomes high temperature air, which is blown by the blower 11 for suction to the compressor 12 on the leeward side to remove the heat of the compressor 12 to further remove the heat of the main body 1. The air is exhausted to the exhaust air passage 17 provided on the back surface.

The high temperature air exhausted into the gap between the legs 14 on the lower surface of the main body 1 is blocked by the partition plate 19 provided on the lower surface of the main body 1, becomes a dead end, and flows backward and is exhausted to the rear surface of the main body 1.

As described above, according to this embodiment, by providing the convex portions 16A and 16B on the left and right of the rear surface of the lower portion of the main body 1, the air passage 17 for exhaust can be secured. Further, the partition plate 19 provided in the gap on the lower surface of the main body 1 blocks the exhaust air to the front surface, and the exhaust gas is exhausted to the air passage 17 on the rear surface of the main body 1.
