Description

Technical Field

[0001] The present application relates to the technical field of refrigeration equipment, and in particular to a refrigerator control method and a refrigerator. Background Art

[0002] Air-cooled refrigerators are generally divided into two types, single-system air-cooled refrigerators and dual-system air-cooled refrigerators. In a single-system air-cooled refrigerator, a freezing evaporator is placed in the freezer. The refrigerant passes through the compressor, condenser, capillary tube, and freezing evaporator and returns to the compressor to form a complete refrigeration cycle. Its advantages are that the volume of the refrigeration duct is relatively small, the refrigerator has a large usable space and low cost. The disadvantages are that the humidity in the refrigerator is low, and the relative humidity in the room is only 15%-40% when the refrigerator is running without load, which is not conducive to the preservation performance. The dual-system air-cooled refrigerator is equipped with an evaporator in the refrigerator and the freezer respectively. The refrigeration evaporator and the freezing evaporator are switched to work separately through the switching valve. The advantage is that the relative humidity in the refrigerator can reach more than 75%, and the preservation effect of fruits and vegetables is good. The disadvantage is that the refrigeration duct components occupy a large volume, which reduces the effective use space of the refrigerator, and the cost of the refrigeration duct components is high. In addition, the dual-system air-cooled refrigerator adds an electric switching valve in the refrigeration system, which further increases the failure rate of the refrigeration system.

[0003] Therefore, the evaporator can be arranged in the middle beam between the refrigerator and the freezer, and the air duct assembly, partition assembly and drain plate can be arranged to realize refrigeration of the refrigerator and the freezer, and the space occupied by the evaporator is reduced. At the same time, the space occupied by the air duct assembly in the cabinet is reduced, which plays a role in expanding the capacity of the cabinet. However, the center-placed evaporator design changes the position of the evaporator of the existing single-cycle air-cooled refrigerator, and the function of the dual-system air-cooled refrigerator to independently control the refrigerator and the freezer cannot be realized. The humidity in the refrigerator compartment of the single-system air-cooled refrigerator is relatively low. Summary of the invention

DETAILED DESCRIPTION

[0049] The following embodiments are described in detail, and examples thereof are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementations described in the following embodiments do not represent all implementations consistent with the present application. They are only examples of systems and methods consistent with some aspects of the present application as detailed in the claims.

[0050] Air-cooled refrigerators are generally divided into two types, single-system air-cooled refrigerators and dual-system air-cooled refrigerators. In a single-system air-cooled refrigerator, a freezing evaporator is placed in the freezer. The refrigerant passes through the compressor, condenser, capillary tube, and freezing evaporator and returns to the compressor to form a complete refrigeration cycle. Its advantages are that the volume of the refrigeration duct is relatively small, the refrigerator has a large usable space and low cost. The disadvantages are that the humidity in the refrigerator is low, and the relative humidity in the room is only 15%-40% when the refrigerator is running without load, which is not conducive to the preservation performance. The dual-system air-cooled refrigerator is equipped with an evaporator in the refrigerator and the freezer respectively. The refrigeration evaporator and the freezing evaporator are switched to work separately through the switching valve. The advantage is that the relative humidity in the refrigerator can reach more than 75%, and the preservation effect of fruits and vegetables is good. The disadvantage is that the refrigeration duct components occupy a large volume, which reduces the effective use space of the refrigerator, and the cost of the refrigeration duct components is high. In addition, the dual-system air-cooled refrigerator adds an electric switching valve in the refrigeration system, which further increases the failure rate of the refrigeration system.

[0051] In some embodiments, the evaporator is arranged at the middle beam between the refrigerator and the freezer, and the air duct assembly, the partition assembly and the drain plate are arranged to realize the refrigeration of the refrigerator and the freezer. In the refrigerator with this structure, the height space occupied by the evaporator is reduced, and the space occupied by the air duct assembly in the cabinet is reduced, which plays a role in expanding the capacity of the cabinet. However, the air duct design of the refrigerator with this structure is to move the evaporator to the middle beam position of the existing single-circulation air-cooled refrigerator through innovative design, reduce the space occupied by the evaporator and the air duct, and cannot realize the function of dual-system independent control of the refrigerator and the freezer, and cannot significantly improve the humidity of the single-system refrigerator.

[0052] In order to solve the problem of low humidity in the refrigerator compartment of a single-system air-cooled refrigerator, some embodiments of the present application provide a refrigerator control method, see Figure 1 , Figure 1 The flow chart of the refrigerator control method provided in the embodiment of the present application specifically includes the following steps:

[0053] S100: Acquire the refrigeration temperature detected by the refrigeration temperature sensor 201 , the freezing temperature detected by the freezing temperature sensor 101 , and the evaporation temperature detected by the evaporation temperature sensor 301 .

[0054] S200: Compare the refrigeration temperature, the freezing temperature, and the evaporation temperature with preset conditions to generate a comparison result.

[0055] The preset conditions include a refrigeration on temperature, a freezing on temperature, a refrigeration off temperature, a freezing off temperature, a first preset temperature, and a second preset temperature. By comparing the refrigeration temperature with the refrigeration off temperature and the refrigeration on temperature, it is determined whether the refrigerator refrigeration chamber 2 needs refrigeration; by comparing the freezing temperature with the refrigeration on temperature and the freezing off temperature, it is determined whether the refrigerator freezer chamber 1 needs refrigeration; by comparing the evaporation temperature with the first preset temperature and the second preset temperature, it is determined whether the refrigerator chamber 2 needs humidification. In the embodiment of the present application, after the comparison result is generated by comparing the refrigeration temperature, the freezing temperature, and the evaporation temperature with the preset conditions, the refrigerator is controlled to operate in different modes.

[0056] S300: According to the comparison result, the refrigerator is controlled to operate in a preset mode.

[0057] Wherein, in some embodiments, Figure 2 As shown, the refrigeration temperature and the freezing temperature are compared with the preset conditions to generate comparison results including:

[0058] If the refrigeration temperature is greater than the refrigeration opening temperature and the freezing temperature is less than the freezing opening temperature and the evaporation temperature is less than the first preset temperature, the refrigeration fan 7 is controlled to start, the first air supply damper 11 and the first return air damper 9 are closed, and the second air inlet damper 10 is opened;

[0059] If the refrigeration temperature is greater than the refrigeration opening temperature and the freezing temperature is less than the freezing opening temperature and the evaporation temperature is greater than the first preset temperature, the compressor is controlled to start, the refrigeration fan 7 is controlled to start, and the second air inlet damper 10 is controlled to open.

[0060] Among them, if the refrigeration temperature is greater than the refrigeration opening temperature and the freezing temperature is less than the freezing opening temperature, the surface refrigeration chamber 2 needs to be refrigerated. At the same time, if the evaporation temperature is less than the first preset temperature, the surface refrigeration chamber 2 needs to be humidified. Therefore, the refrigeration fan 7 can be controlled to start, the second air inlet damper 10 can be opened, and the first air supply damper 11 and the first return air damper 9 can be closed. After humidifying the refrigeration chamber 2 by opening the second air inlet damper 10, the compressor is started and the second air inlet damper 10 is opened to cool the refrigeration chamber 2.

[0061] When the refrigerating chamber 2 needs to be refrigerated and the evaporating temperature is greater than the first preset temperature, the refrigerating chamber 2 does not need to be humidified. Therefore, the compressor can be directly controlled to start and the second air inlet damper 10 can be opened to provide cooling for the refrigerating chamber 2.

[0062] Among them, it can be understood that the opening and closing of the first supply air damper 11 and the first return air damper 9 control the refrigeration of the freezer chamber 1, and the opening and closing of the second air inlet damper 10 controls the refrigeration of the refrigerator chamber 2. When the second air inlet damper 10 is closed, the low-temperature gas generated by the evaporator 3 cannot enter the refrigerator chamber 2. When the second air inlet damper 10 is opened, the refrigeration fan 7 can send high-humidity gas into the refrigerator chamber 2 through the second air inlet damper 10 to increase the humidity in the refrigerator chamber 2.

[0063] In some embodiments, comparing the refrigerated temperature and the frozen temperature with the preset conditions to generate a comparison result further includes:

[0064] If the refrigeration temperature is greater than the refrigeration opening temperature and the freezing temperature is greater than the freezing opening temperature, the compressor and the refrigeration fan 7 are controlled to start, and the second air inlet damper 10 is opened;

[0065] If the evaporation temperature is lower than the second preset temperature, the first air inlet damper 8 and the first air return damper 9 are controlled to open.

[0066] Among them, if the refrigeration temperature is greater than the refrigeration opening temperature and the freezing temperature is greater than the freezing opening temperature, it means that both the refrigerating chamber 2 and the freezing chamber 1 need refrigeration. Therefore, the refrigeration fan 7 can be notified to start, and the second air inlet damper 10 can be opened to cool the refrigerating chamber 2, and the first air inlet damper 8 and the first return air damper 9 can be opened to cool the freezing chamber 1.

[0067] In some embodiments, comparing the refrigerated temperature and the frozen temperature with the preset conditions to generate a comparison result further includes:

[0068] If the refrigeration temperature is lower than the refrigeration closing temperature, the second air inlet damper 10 is controlled to close;

[0069] If the freezing temperature is lower than the freezing shut-off temperature, the compressor is controlled to shut down, and the first air supply damper 11 and the first air return damper 9 are closed.

[0070] Among them, during the refrigeration process of the refrigerator compartment 2 and the freezer compartment 1, when the refrigeration temperature is lower than the refrigeration shut-off temperature, it appears that the temperature in the refrigerator compartment 2 has reached the target temperature of the refrigerator compartment 2, so the refrigeration of the refrigerator compartment 2 can be stopped by closing the second air inlet damper 10. When the temperature in the freezer compartment 1 reaches the target temperature of the freezer compartment 1, the refrigeration of the freezer compartment 1 can be stopped by closing the compressor, the first air inlet damper 8 and the first return air damper 9. During the use of the refrigerator, the temperature of the freezer compartment 1 is lower than the temperature of the refrigerator compartment 2, so the time for the freezer compartment 1 to reach the freezing shut-off temperature is longer than the time for the refrigerator compartment 2 to reach the refrigerator compartment 2 shut-off temperature. Therefore, when the refrigerator compartment 2 stops refrigeration, there is no need to shut down the compressor, only the second air inlet damper 10 needs to be closed. When the freezer compartment 1 stops refrigeration, the compressor needs to be shut down to reduce energy consumption.

[0071] In some embodiments, comparing the refrigerated temperature and the frozen temperature with the preset conditions to generate a comparison result further includes:

[0072] If the refrigeration temperature is greater than the refrigeration closing temperature and the refrigeration temperature is less than the refrigeration opening temperature and the freezing temperature is greater than the freezing opening temperature, the compressor is controlled to start, the first air inlet damper 8 and the first return air damper 9 are opened, and the second air inlet damper 10 and the second return air damper 13 are closed.

[0073] Among them, when the refrigeration temperature is greater than the refrigeration closing temperature and the refrigeration temperature is lower than the refrigeration opening temperature, the surface refrigeration chamber 2 does not need to be refrigerated. Therefore, it is judged whether the freezing temperature is greater than the freezing opening temperature. When the freezing temperature is greater than the freezing opening temperature, the surface freezer chamber 1 needs to be refrigerated separately. Therefore, the compressor can be controlled to start, and the first air inlet damper 8 and the first return air damper 9 are opened to provide cooling for the freezer chamber 1. At the same time, the refrigeration chamber 2 does not need to be refrigerated, so the second air inlet damper 10 can be controlled to be closed, so that the cold air cannot enter the refrigeration chamber 2, thereby improving the cooling efficiency of the freezer chamber 1.

[0074] In some embodiments, comparing the refrigerated temperature and the frozen temperature with the preset conditions to generate a comparison result further includes:

[0075] If the freezing temperature is lower than the freezing closing temperature and the refrigerating temperature is lower than the refrigerating opening temperature and the evaporating temperature is lower than the first preset temperature, the refrigeration fan 7 is controlled to start, the second air inlet damper 10 is opened, and the first air supply damper 11 and the first air return damper 9 are closed;

[0076] If the freezing temperature is lower than the freezing closing temperature and the refrigerating temperature is lower than the refrigerating opening temperature and the evaporating temperature is higher than the first preset temperature; the refrigeration fan 7 and the second air inlet damper 10 are controlled to be closed.

[0077] Among them, if the freezing temperature is lower than the freezing closing temperature, the surface freezing chamber 1 does not need to be refrigerated, so the first air supply damper 11 and the first air return damper 9 can be closed to reduce the heat exchange between the freezing chamber 1 and the outside air. If the refrigeration temperature is lower than the refrigeration opening temperature and the evaporation temperature is lower than the first preset temperature, the surface refrigeration chamber 2 needs to be humidified, and the second air inlet damper 10 can be opened to transport the outside air with high humidity into the refrigeration chamber 2 through the refrigeration fan 7 to increase the humidity in the refrigeration chamber 2. When the temperature of the evaporator 3 is greater than or lower than the preset temperature, the humidification of the surface refrigeration chamber 2 is completed, and the refrigeration fan 7 and the second air inlet damper 10 can be closed to close the circulation channel between the refrigeration chamber 2 and the outside air.

[0078] In some embodiments, the refrigeration opening temperature, the refrigeration closing temperature, the freezing opening temperature, and the freezing closing temperature are all associated with the refrigerator refrigeration gear. For example, the refrigeration opening temperature is 2-10°C, the refrigeration closing temperature is 0-8°C, the freezing opening temperature is -12°C--22°C, and the freezing closing temperature is -16°C--26°C. The refrigeration opening temperature, the freezing closing temperature, the freezing opening temperature, and the freezing closing temperature all change with the refrigerator refrigeration gear.

[0079] In addition, the first preset temperature is -5°C to -1°C, and the second preset temperature is -15°C to -25°C.
