[0054] The embodiments of the present application provide a refrigeration component and a drainage control method thereof, a refrigerator, and a control device to solve the problem that the water receiving tray of the existing refrigerator discharges water to the outside of the refrigerator through a drainage pipe, thereby causing the floor to be slippery and water to accumulate. The following will be explained in conjunction with the accompanying drawings.

[0055] The refrigeration assembly provided in the embodiment of the present application is applied to a refrigerator. Figure 1 , Figure 1 The schematic diagram of the structure of the refrigeration assembly provided in the embodiment of the present application includes an evaporator 1, a heater, a water tray 2 and a compressor 3. The heater is used to heat and defrost the evaporator 1; the water tray 2 is arranged at the bottom of the evaporator 1 along the gravity direction, and the water tray 2 is used to receive the defrosted water of the evaporator 1; the compressor 3 includes an exhaust pipe 31, and the exhaust pipe 31 is at least partially adjacent to the water tray 2; wherein, when the compressor 3 is turned on, the exhaust pipe 31 heats the water tray 2 to evaporate the defrosted water. The position and type of the heater are not further limited here.

[0056] The refrigeration assembly provided in the embodiment of the present application sets a part of the pipe section of the exhaust pipe 31 of the compressor 3 adjacent to the water receiving pan 2. When the compressor 3 is turned on, the high-temperature refrigerant will be discharged to the exhaust pipe 31. Therefore, the temperature of the exhaust pipe 31 is relatively high at this time, thereby heating the adjacent water receiving pan 2, so that the defrosting water in the water receiving pan 2 evaporates, thereby draining the water receiving pan 2, avoiding the water in the water receiving pan 2 from being directly discharged to the ground, causing the ground to be slippery, water accumulation and other inconveniences. At the same time, by using the heat of the exhaust pipe 31 when the compressor 3 is turned on to drain the water receiving pan 2, the energy consumption is relatively low. Compared with the evaporation method of additionally setting a heating wire to heat the water receiving pan 2, the drainage method provided by the present application is lower in cost and consumes less energy.

[0057] Optionally, at least part of the exhaust pipe 31 is arranged above the water receiving pan 2 along the gravity direction, that is, located on the side of the water receiving pan 2 facing the evaporator 1. That is, this part of the exhaust pipe 31 is closest to the defrost water in the water receiving pan 2, and can evaporate the defrost water with maximum efficiency, thereby increasing the drainage speed. It is understandable that the wall of the exhaust pipe 31 is made of heat-conducting material, so as to guide the heat of the high-temperature refrigerant in the exhaust pipe 31 to the surrounding air, and then transfer it to the defrost water in the water receiving pan 2 through the surrounding air.

[0058] Optionally, the refrigeration assembly provided in the embodiment of the present application further includes a pressure detection component 4, which is arranged at the bottom of the water receiving tray 2. When the detection result of the pressure detection component 4 is greater than the first preset pressure value, the compressor 3 is turned on. Specifically, the pressure detection component 4 can be a pressure sensor. The specific value of the first preset pressure value is not further limited here.

[0059] When the shape of the water receiving tray 2 is irregular, it is difficult to calculate the volume of the defrost water in the water receiving tray 2 and the accuracy is low. Therefore, a pressure detection component 4 is provided to detect the weight of the defrost water in the water receiving tray 2. The water content of the water receiving tray 2 is obtained by detecting the weight of the defrost water, thereby ensuring the accuracy of the detection of the water content of the water receiving tray 2 and reducing the shape requirements of the water receiving tray 2. When the detection result of the pressure detection component 4 is greater than the first preset pressure value, that is, when a large amount of water accumulates in the water receiving tray 2, the compressor 3 is directly forced to start up to avoid the water in the water receiving tray 2 from continuously rising and causing the water to overflow, thereby affecting the operation of other components such as short circuit.

[0060] The embodiment of the present application also provides a drainage control method, which is applied to a refrigerator and is suitable for the refrigeration assembly as described above. The refrigeration assembly includes an evaporator 1, a heater, a water receiving tray 2, and a compressor 3. The heater is used to heat and defrost the evaporator 1; the water receiving tray 2 is arranged at the bottom of the evaporator 1 along the gravity direction, and the water receiving tray 2 is used to receive the defrosted water of the evaporator 1; the compressor 3 includes an exhaust pipe 31, and the exhaust pipe 31 is at least partially adjacent to the water receiving tray 2; wherein, when the compressor 3 is turned on, the exhaust pipe 31 heats the water receiving tray 2 to evaporate the defrosted water. The refrigeration assembly also includes a pressure detection component 4, which is arranged at the bottom of the water receiving tray 2, see Figure 2 and Figure 3 , Figure 2 This is a usage scenario diagram of the drainage control method provided in the embodiment of the present application. Figure 3 This is a flow chart of a drainage control method provided in an embodiment of the present application. The drainage control method comprises the following steps:

[0061] Step S101: when the refrigerator enters the defrosting cycle, the heater is controlled to heat the evaporator 1, and the detection result of the pressure detection component 4 is obtained;

[0062] Step S102: If the detection result is greater than the first preset pressure value, the compressor 3 is controlled to start;

[0063] Step S103: If the detection result is less than or equal to the first preset pressure value, the compressor 3 is controlled to start up after the refrigerator enters a refrigeration cycle.

[0064] When the refrigerator enters the defrosting cycle, the heater can be turned on for defrosting. The pressure of the water tray 2 is detected. When the detection result is less than or equal to the first preset pressure value, it indicates that the defrosting water in the water tray 2 is small and will not overflow from the water tray 2 and affect the normal operation of the refrigerator. Therefore, the heater can continue to work normally to defrost the evaporator 1 and complete the defrosting operation of the evaporator 1. After the refrigerator defrosts, when it enters the refrigeration cycle, the high-temperature refrigerant in the exhaust pipe 31 after the compressor 3 is turned on is used to directly heat and evaporate the defrosting water in the water tray 2 to achieve drainage of the water tray 2, which not only ensures the normal refrigeration of the refrigerator, but also avoids directly draining the defrosting water to the ground to affect the home environment. At the same time, it has low energy consumption and low cost. When the detection result is greater than the first preset pressure value, it indicates that there is a lot of defrosting water in the water tray 2. If it is not drained in time, the water will soon overflow. Therefore, the compressor 3 is immediately forced to start, and the water tray 2 is drained to prevent overflow.

[0065] Optionally, if the detection result in step S102 is greater than the first preset pressure value, after the compressor 3 is controlled to start, the method further includes:

[0066] Step S1021: After the first preset time period, the detection result of the pressure detection component 4 is obtained again.

[0067] Step S1022: If the detection result is greater than the first preset pressure value and less than the second preset pressure value, the heating power of the heater is controlled to be reduced by the first preset power based on the current power; the first preset power is not further limited here.

[0068] Step S1023: If the detection result is greater than or equal to the second preset pressure value, the heater is controlled to be turned off;

[0069] Step S1024: If the detection result is less than or equal to the first preset pressure value, the compressor 3 is controlled to shut down. The first preset pressure value is less than the second preset pressure value.

[0070] Since the heater is still heating, the defrost water in the water receiving pan 2 may continue to rise after the compressor 3 is turned on for the first preset time. Therefore, the detection result of the pressure detection component 4 is obtained again after the first preset time. When the detection result is greater than the first preset pressure value and less than the second preset pressure value, it indicates that the defrost water is still rising, but there is still a certain distance from the opening of the water receiving pan 2. Therefore, the heating power of the heater is first controlled to reduce the first preset power based on the current power, that is, the power of the heater is reduced, thereby slowing down the melting speed of the frost layer on the evaporator 1 and reducing the water level rising speed in the water receiving pan 2. degree, while keeping the compressor 3 turned on to continue evaporating and draining water; when the detection result is greater than or equal to the second preset pressure value, it indicates that the defrost water is still rising and is close to the opening of the water receiving pan 2 and is about to overflow the water receiving pan 2, so the heater is directly controlled to be turned off to minimize the rising speed of the water level in the water receiving pan 2 and keep the compressor 3 turned on to continue evaporating and draining water; when the detection result is less than or equal to the first preset pressure value, it indicates that the water level in the water receiving pan 2 is more appropriate at this time and there is no risk of overflow, so the compressor 3 is controlled to be turned off to reduce the impact on the defrosting effect of the heater and increase the defrosting speed.

[0071] Optionally, after controlling the heating power of the heater to reduce the first preset power based on the current power in step S1022, the method further includes:

[0072] Step S10221: After the second preset time, the detection result of the pressure detection component 4 is obtained again;

[0073] Step S10222: If the detection result is greater than the first preset pressure value and less than the second preset pressure value, the operating power of the compressor 3 is controlled to increase the second preset power based on the current power. The second preset power is not further limited here.

[0074] After reducing the heating power of the heater to slow down the rising speed of the water level in the water receiving pan 2, the pressure value of the water receiving pan 2 is obtained again at the second preset time. If the detection result is greater than the first preset pressure value and less than the second preset pressure value, it indicates that after the heating power of the heater is reduced, the drainage speed of the defrost water in the water receiving pan 2 is still not ideal, resulting in the water level in the water receiving pan 2 is still high at this time. Therefore, the operating power of the compressor 3 is further increased to increase the flow rate of the high-temperature refrigerant in the exhaust pipe 31, thereby improving the heat exchange efficiency between the exhaust pipe 31 and the defrost water, so as to accelerate the evaporation rate of the defrost water.

[0075] Optionally, after step S10221, the method further includes: if the detection result is less than or equal to the first preset pressure value, controlling the heater to continue to operate based on the operating power after reducing the first preset power, and controlling the compressor 3 to stop.

[0076] Since the detection result is less than or equal to the first preset pressure value, it indicates that the water level in the water receiving pan 2 is within the appropriate receiving range and no drainage is required, so the compressor 3 is controlled to stop to reduce the defrosting effect on the evaporator 1. At the same time, since the heater continues to operate based on the operating power after reducing the first preset power, the water level rising speed in the water receiving pan 2 is reduced, avoiding the detection result of the pressure detection component 4 being greater than the first preset pressure value in a short period of time, which causes the compressor 3 to start and stop frequently.

[0077] Optionally, after controlling the heater to be turned off in step S1023, the method further includes:

[0078] Step S10231: After the third preset time, the detection result of the pressure detection component 4 is obtained again;

[0079] Step S10232: If the detection result is greater than or equal to the second preset pressure value, the compressor 3 is controlled to operate at a first power, wherein the first power is the maximum power of the compressor 3 .

[0080] If the detection result is greater than or equal to the second preset pressure value, it indicates that the water level in the water receiving pan 2 is close to the opening of the water receiving pan 2 and is about to overflow the water receiving pan 2. After the heater is controlled to be turned off, the frost layer on the evaporator 1 continues to melt. If the detection result is still greater than or equal to the second preset pressure value after the third preset time, it indicates that the evaporation rate of the defrost water is not enough to compensate for the rising rate of the water level in the water receiving pan 2. Therefore, the power of the compressor 3 is directly adjusted to the first power, i.e., the maximum power, to maximize the drainage efficiency and avoid water overflow.

[0081] Optionally, if the detection result in step S103 is less than or equal to the first preset pressure value, the compressor 3 is controlled to start up after the refrigerator enters a refrigeration cycle, including:

[0082] Step S1031: If the detection result is greater than the third preset pressure value and less than or equal to the first preset pressure value, the compressor 3 is controlled to start and run for a first operating time after the refrigerator enters a refrigeration cycle.

[0083] That is, when the detection result is greater than the third preset pressure value and less than or equal to the first preset pressure value, it indicates that the water level of the defrost water in the water receiving tray 2 is relatively appropriate and there is no risk of overflow in a short time. However, the capacity of the defrost water is large, so the compressor 3 can be kept turned off in the current defrost cycle to ensure a good defrost environment for the evaporator 1. After the defrost is completed, when the refrigerator enters the next refrigeration cycle, the refrigeration time can be appropriately extended based on the normal refrigeration cycle to ensure that all the defrost water in the water receiving tray 2 can be evaporated and drained, avoiding affecting the water receiving capacity of the water receiving tray 2 in the next defrost cycle of the refrigerator. For details, please refer to subsequent steps S10311 to S10312.

[0084] Step S1032: If the detection result is less than or equal to the third preset pressure value, the compressor 3 is controlled to start and run for a second operating time after the refrigerator enters the refrigeration cycle; wherein the third preset pressure value is less than the first preset pressure value, and the first operating time is greater than the second operating time.

[0085] When the detection result is less than or equal to the third preset pressure value, it indicates that the defrost water capacity in the water receiving tray 2 is small, and the normal refrigeration time of the refrigerator can meet the evaporation of all the currently accumulated defrost water. Therefore, the compressor 3 is kept turned off in the current defrost cycle to ensure a good defrost environment for the evaporator 1. After the defrost is completed, when the refrigerator enters the next refrigeration cycle, the compressor 3 is turned on normally for refrigeration, and the high-temperature refrigerant in the exhaust pipe 31 is used to directly evaporate the defrost water. There is no need to extend the normal working time of the compressor 3, which ensures the smooth discharge of the defrost water in the water receiving tray 2 while saving energy and time. For details, please refer to the subsequent steps S10321 to S10322.

[0086] Optionally, in step S1031, when the refrigerator enters a refrigeration cycle, controlling the compressor 3 to start and run for a first running time includes:

[0087] Step S10311: When the temperature of the freezing chamber rises to a first preset temperature, the compressor 3 is controlled to turn on;

[0088] Step S10312: When the temperature of the freezing chamber drops to a second preset temperature, the compressor 3 is controlled to be turned off; wherein the first preset temperature is higher than the second preset temperature.

[0089] That is, the start point and stop point of compressor 3 are based on the temperature of the freezer compartment. When the temperature of the freezer compartment reaches the first preset temperature, compressor 3 is controlled to start. When the temperature of the freezer compartment drops to the second preset temperature, indicating that the current temperature in the freezer compartment has reached the ideal set temperature, compressor 3 is controlled to stop to complete the refrigeration of the refrigeration cycle.

[0090] Optionally, in step S1032, when the refrigerator enters the refrigeration cycle, the compressor 3 is controlled to start and run for a second operation time, including:

[0091] Step S10321: When the temperature of the freezing chamber rises to a third preset temperature, the compressor 3 is controlled to turn on;

[0092] Step S10322: When the temperature of the freezing chamber drops to a fourth preset temperature, the compressor 3 is controlled to be turned off;

[0093] Among them, the first preset temperature, the third preset temperature, the fourth preset temperature and the second preset temperature decrease in sequence.

[0094] It can be understood that since the first preset temperature is higher than the third preset temperature and the second preset temperature is lower than the fourth preset temperature, when the refrigerator executes step S10311 and step S10312, the temperature difference between the start point and the stop point of the compressor 3 is larger, and the required refrigeration time is longer, so that the first operating time is greater than the second operating time, and when the detection result of the pressure detection component 4 is greater than the third preset pressure value and less than or equal to the first preset pressure value, that is, when there is more defrost water, the compressor 3 can be turned on for a long enough time to allow all the defrost water to evaporate.
