Description

Air-cooled compressor refrigeration refrigerator with moisturizing function

technical field

The utility model relates to the technical field of air-cooled refrigeration, in particular to a refrigerator with an air-cooled compressor refrigeration and moisturizing function.

Background technique

The air-cooled refrigerator uses the cold air generated by the evaporator hidden in the freezer to circulate forcibly with a fan to cool down the refrigerator and freezer. Compared with direct cooling refrigerators, air-cooled frost-free refrigerators have the advantages of automatic defrosting, fast cooling speed, good temperature uniformity and precise temperature control. In terms of research and development, air-cooled refrigerators or freezers have absolute advantages in terms of cold distribution. However, from the analysis of the flow of moisture with the moving airflow during the cooling operation of the refrigerator or freezer, the refrigerator or freezer will continuously bring the moisture in the box to the evaporator, and discharge the box through the defrosting tube during the defrosting process, resulting in The water loss in the refrigerator is not conducive to the preservation of fresh food.

The purpose of this utility model is to provide an air-cooled compressor refrigerated refrigerator with moisturizing function, so as to solve the problems raised in the above-mentioned background technology.

In order to achieve the above object, the utility model provides the following technical solutions:

An air-cooled compressor refrigerated refrigerator with moisturizing function, comprising a cabinet and a refrigerator, the refrigerator is placed inside the cabinet, the bottom of the back of the cabinet is provided with a press chamber, and a pressure chamber is fixed inside the chamber. An air duct is provided between the back of the cabinet and the refrigerating room, an evaporator is fixed in the air duct, and an evaporator sensor is provided on the evaporator; an air outlet and a return air are respectively provided at the upper and lower parts of the refrigerating room, and the air outlet Both the air outlet and the return air outlet are connected with the air duct, and the inside of the refrigerator is equipped with a sensor in the box; the bottom of the air duct is provided with a water receiving dish, which is arranged on the upper part of the press chamber but not connected with it, and the air duct The upper part is provided with a fan, and the position of the fan corresponds to the air outlet.

As a further solution of the utility model: the bottom of the air duct is provided with a water receiving dish, and the water receiving dish is arranged on the upper part of the press chamber but not communicated with it.

As a further solution of the present utility model: the water receiving dish is made of aluminum material.

As a further solution of the utility model: the compressor, the fan, the evaporator sensor and the sensor in the box are electrically connected to the input end of the power supply.

Compared with the prior art, the utility model has the beneficial effects of: increasing the evaporation temperature on the evaporator to -6°C~-4°C, allowing the evaporator to maintain a sufficient margin, which is 1.5 times the cooling capacity, and flexible The heat of the press is used to defrost, so as to compensate the moisture in the refrigerator. At the same time, the water receiver set in the refrigerator can collect the liquefied water and replenish the moisture in the refrigerator, so as to ensure that the humidity in the refrigerator is within a certain range. Inside, the defrosting method adopts natural defrosting, which is more safe and reliable while saving energy. The utility model is simple in design, reasonable in structure, has the advantages of good moisturizing effect, low cost, safety and reliability, etc., and has good marketability .

detailed description

The technical solution of this patent will be further described in detail below in conjunction with specific embodiments.

Please refer to Fig. 1, an air-cooled compressor refrigeration refrigerator with moisturizing function, including a cabinet 1 and a refrigerator compartment 2, the refrigerator compartment 2 is placed inside the cabinet 1, and the bottom of the cabinet 1 back is provided with a press The machine compartment 6 and the compressor compartment 6 are fixed with a compressor 5; an air duct 7 is provided between the back of the cabinet 1 and the refrigerator room 2, and an evaporator 8 is fixed in the air duct 7, and an evaporator is arranged on the evaporator 8 The sensor 9 and the evaporator sensor 9 are used to monitor the surface temperature of the evaporator 8; the upper and lower parts of the refrigerator compartment 2 are respectively provided with an air outlet 11 and a return air outlet 4, and the air outlet 11 and the return air outlet 4 are all communicated with the air duct 7, The interior of the refrigerator compartment 2 is provided with a sensor 3 in the box, and the sensor 3 in the box is used to monitor the temperature in the refrigerator compartment 2; Not connected to it, the upper part of the air duct 7 is provided with a fan 10 , and the position of the fan 10 corresponds to the air outlet 11 .

The water receiving dish 12 is made of aluminum material.

The compressor 5, fan 10, evaporator sensor 9 and in-box sensor 3 are electrically connected to the input end of the power supply.

The utility model allows the evaporator 8 to maintain a sufficient margin, which is 1.5 times the cooling capacity, by increasing the evaporation temperature on the evaporator 8 to -6°C~-4°C. When the temperature is higher than the set value, the compressor 5 starts to work, the evaporator 8 starts to refrigerate, and the fan 10 runs at high speed to reduce the accumulation and frosting of the cold on the evaporator 8, and reduce the humidity fluctuation in the refrigerating room 2; when the refrigerating room When the sensor 3 inside the box monitors that the temperature in the box reaches the set temperature, the compressor 5 stops, and the fan 10 continues to run at a low speed to realize natural defrosting until the evaporator sensor 9 detects that the temperature of the evaporator 8 reaches the set value In this way, the frost on the evaporator 8 can be vaporized into the refrigerator compartment 2, and the liquefied water is collected by the water receiving dish 12 at the same time. During the start and stop of the compressor 5, the heat transferred from the compressor compartment 6 and the air in the box The circulating return air re-vaporizes the water in the water receiving dish 12 into the air in the cold storage room 2 to ensure that the humidity in the cold storage room 2 is stable within a certain range.

The preferred implementation of this patent has been described in detail above, but this patent is not limited to the above-mentioned implementation, and within the knowledge of those of ordinary skill in the art, it can also be made without departing from the purpose of this patent. Various changes.
