Description

Universal integrated refrigeration device and freezer containing the device

technical field

The utility model relates to the technical field of refrigerator manufacturing, in particular to a general integrated refrigeration device and a refrigerator containing the device.

Background technique

Most of the existing horizontal refrigerators are direct-cooling horizontal refrigerators, which have a freezer chamber formed by an inner container, and an insulating material is filled between the inner container and the outer shell. The evaporator of the refrigeration system of the direct cooling type horizontal freezer is usually attached to the inner wall, the condenser is attached to the wall of the box shell or installed in the engine room, the compressor and other components are placed in the engine room, and when the cooling is running, the inside of the box passes through evaporation. The cooling device cools the inner tank in contact with it, and then spreads it into the box through natural convection heat exchange for cooling. This refrigeration method has the following defects: 1. The static heat exchange refrigeration speed is slow, and the air flow changes slowly, resulting in a large gradient in the temperature field. The general temperature difference can reach more than 5°C, and the refrigeration effect is not good; 2. Direct cooling products are in the It is easy to accumulate too much frost on the inner tank or the surface of the evaporator, which will reduce the heat exchange efficiency and affect the use. Therefore, users need to manually defrost regularly, which is very inconvenient; 3. The evaporator of the horizontal freezer is usually embedded in the foam insulation Inside the material, once the pipeline rusts and leaks, it will not be repaired, and the whole machine will be declared scrapped, resulting in a waste of resources.

In order to solve the above technical problems, the following two technical solutions are often used at present: 1. Add a fan in the freezer box to force the gas in the box to convect through the fan, artificially interfere with the distribution of the temperature field, and make the inner tank and The cooling capacity of the evaporator is transferred out as soon as possible. The cooling speed of the refrigerator adopting this method is faster, but the evaporator and some condensers are still buried in the insulation material. Once the leakage of the refrigeration pipeline occurs, it will not be repaired. The whole machine can only be scrapped, but other parts on the freezer are normal, which greatly wastes resources; 2. Change the entire refrigeration method to full air cooling, that is, no longer pre-embed the refrigeration pipeline in the insulation material, Instead, use a forced convection heat exchanger and add an evaporating fan. The evaporator and evaporating fan are installed in the box, and the condenser, condensing fan, compressor and related electrical control components are installed in the engine room. This method is better than the previous scheme. The cooling speed is faster, the effect is better, and it can also realize automatic frosting. All the pipelines are installed after the foaming is completed, and they are exposed and visible. If there is a failure, it can be repaired directly, and there will be no leakage due to a section of the pipeline. That is, the waste of resources when the whole machine is scrapped. However, the evaporating fan and evaporator of this kind of freezer are installed inside the box, and the compressor, condenser and other components are installed outside the box. The assembly line operation is more complicated during production, and the welding process needs to be carried out directly on the box of the freezer. Design It is more complicated, and if a fault occurs during the user's use, the whole machine needs to be taken away for maintenance, causing the user to have no freezer available, which affects the user's life or business use.

In order to solve the above technical problems, an existing technology is that the refrigeration system on the refrigerator is integrated into an integral unit that can be disassembled as a whole. The evaporating assembly includes an evaporator, an outer cover and a fan, the condensing assembly includes a compressor and a condenser, the evaporating assembly and the condensing assembly are operatively connected to each other, the evaporating assembly and the condensing assembly are integrated and installed on the bottom frame, and can be Installed on the side of the freezer in a push-pull manner, the evaporator and the fan are arranged in the outer cover, and the bottom and the outer side of the outer cover are provided with an insulating layer to separate from the condensing component and the external environment. Although the integrated refrigeration device installed on the side can solve the above problems, the size of the structure is irregular, and it is installed on a frame. The efficiency is low, the size of the air duct is complex and the shape needs to be matched with a special box, and the interchangeability between different types of refrigerators is poor, and it cannot be truly universalized and standardized.
