[0027] If the detection result is greater than or equal to the second preset pressure value, the compressor is controlled to operate at a first power.

[0028] Optionally, if the detection result is less than or equal to the first preset pressure value, the compressor is controlled to start when the refrigerator enters a refrigeration cycle, comprising:

[0029] If the detection result is greater than a third preset pressure value and less than or equal to the first preset pressure value, the compressor is controlled to start and operate for a first operating time period when the refrigerator enters a refrigeration cycle.

[0054] This application provides a refrigeration component and its drainage control method, a refrigerator, and a control device to solve the problems of existing refrigerators draining water from the drip tray to the outside of the refrigerator through the drain pipe, which leads to slippery floors and water accumulation. The following description is in conjunction with the accompanying drawings.

[0055] The refrigeration component provided in this application embodiment is applied to a refrigerator. Please refer to [link / reference]. Figure 1 , Figure 1 This is a schematic diagram of the structure of a refrigeration assembly provided in an embodiment of this application. The refrigeration assembly includes an evaporator 1, a heater, a drip tray 2, and a compressor 3. The heater is used to heat the evaporator 1 for defrosting; the drip tray 2 is disposed at the bottom of the evaporator 1 along the direction of gravity and is used to collect the defrosting water from the evaporator 1; the compressor 3 includes an exhaust pipe 31, which is at least partially adjacent to the drip tray 2; wherein, when the compressor 3 is turned on, the exhaust pipe 31 heats the drip tray 2 to evaporate the defrosting water. The location and type of the heater are not further limited here.

[0056] The refrigeration assembly provided in this application configures a portion of the exhaust pipe 31 of the compressor 3 to be adjacent to the drip tray 2. When the compressor 3 is turned on, it discharges high-temperature refrigerant into the exhaust pipe 31. Therefore, the high temperature of the exhaust pipe 31 heats the adjacent drip tray 2, causing the defrost water in the drip tray 2 to evaporate and drain. This avoids directly discharging water from the drip tray 2 onto the ground, preventing slippery surfaces and water accumulation. Furthermore, by utilizing the heat from the exhaust pipe 31 when the compressor 3 is running to drain the water from the drip tray 2, energy consumption is lower. Compared to the method of using an additional heating wire to heat the drip tray 2 for evaporation, the drainage method provided in this application is more cost-effective and consumes less energy.

[0057] Optionally, the vent pipe 31 is at least partially positioned above the drip tray 2 along the direction of gravity, i.e., on the side of the drip tray 2 facing the evaporator 1. This portion of the vent pipe 31 is closest to the defrost water in the drip tray 2, maximizing the evaporation efficiency of the defrost water and increasing the drainage speed. It is understood that the wall of the vent pipe 31 is made of a thermally conductive material to conduct the heat from the high-temperature refrigerant within the vent pipe 31 into the surrounding air, which is then transferred to the defrost water in the drip tray 2.

[0058] Optionally, the refrigeration assembly provided in this embodiment further includes a pressure detection element 4, which is disposed at the bottom of the water receiving tray 2. When the detection result of the pressure detection element 4 is greater than a first preset pressure value, the compressor 3 is turned on. Specifically, the pressure detection element 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 drip tray 2 is irregular, it is difficult and inaccurate to calculate the volume of defrost water in the drip tray 2. Therefore, a pressure detection device 4 is set to detect the weight of defrost water in the drip tray 2. By detecting the weight of defrost water, the water level in the drip tray 2 can be obtained, ensuring the accuracy of the water level detection and reducing the shape requirements of the drip tray 2. When the detection result of the pressure detection device 4 is greater than the first preset pressure value, that is, when there is a lot of water accumulated in the drip tray 2, the compressor 3 is directly forced to start, to avoid the water in the drip tray 2 from continuing to rise and overflowing, which would affect the operation of other components such as short circuits.

[0060] This application also provides a drainage control method applied to a refrigerator, suitable for the refrigeration components described above. The refrigeration components include an evaporator 1, a heater, a drip tray 2, and a compressor 3. The heater is used to heat the evaporator 1 for defrosting; the drip tray 2 is disposed at the bottom of the evaporator 1 along the direction of gravity and is used to collect the defrosting water from the evaporator 1; the compressor 3 includes an exhaust pipe 31, which is at least partially adjacent to the drip tray 2; wherein, when the compressor 3 is turned on, the exhaust pipe 31 heats the drip tray 2 to evaporate the defrosting water. The refrigeration components also include a pressure detection element 4, which is disposed at the bottom of the drip tray 2. Please refer to [link to relevant documentation]. Figure 2 and Figure 3 , Figure 2 This is a diagram illustrating a usage scenario of the drainage control method provided in an embodiment of this application. Figure 3 A flowchart of a drainage control method provided in this application embodiment, the drainage control method including the following steps:

[0061] Step S101: When the refrigerator enters the defrosting cycle, control the heater to heat the evaporator 1 and obtain the detection result of the pressure detection element 4;

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

[0063] Step S103: If the detection result is less than or equal to the first preset pressure value, then control the compressor 3 to start when the refrigerator enters the cooling cycle.

[0064] Once the refrigerator enters the defrost cycle, the heater can be turned on to defrost. The pressure in the drip tray 2 is monitored. If the pressure is less than or equal to the first preset pressure value, it indicates that there is little defrost water in the drip tray 2, which will not overflow and affect the normal operation of the refrigerator. Therefore, the heater can continue to work normally to defrost the evaporator 1. After defrosting, when the refrigerator enters the cooling cycle, the high-temperature refrigerant in the exhaust pipe 31 of the compressor 3 is turned on directly heats and evaporates the defrost water in the drip tray 2, thus draining the water. This ensures normal cooling while preventing defrost water from being directly discharged onto the floor and affecting the home environment. It also has low energy consumption and low cost. If the pressure exceeds the first preset pressure value, it indicates that there is a lot of defrost water in the drip tray 2. If it is not drained in time, it will soon overflow. Therefore, the compressor 3 is immediately forced to start to drain the water from the drip tray 2 to prevent overflow.

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

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

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

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

[0069] Step S1024: If the detection result is less than or equal to the first preset pressure value, then control the compressor 3 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 drip tray 2 may continue to rise after the compressor 3 has been running for the first preset time. Therefore, the pressure detection result of the pressure sensor 4 is retrieved again after the first preset time. If the detection result is greater than the first preset pressure value but less than the second preset pressure value, it indicates that the defrost water is still rising, but there is still a certain distance between the water level and the opening of the drip tray 2. Therefore, the heating power of the heater is first reduced by the first preset power based on the current power, that is, the power of the heater is reduced, thereby slowing down the melting rate of the frost layer on the evaporator 1 and reducing the rate of rise of the water level in the drip tray 2. At the same time, the compressor 3 is kept running to continue evaporating and draining water. When the detection result is equal to or greater than the second preset pressure value, it indicates that the defrosting water is still rising and is close to the opening of the water tray 2 and is about to overflow. Therefore, the heater is directly turned off to minimize the rate of water level rise in the water tray 2, and the compressor 3 is kept running 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 tray 2 is appropriate and there is no risk of overflow. Therefore, the compressor 3 is turned off to reduce the impact on the defrosting effect of the heater and improve the defrosting speed.

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

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

[0073] Step S10222: If the detection result is greater than the first preset pressure value and less than the second preset pressure value, then control the operating power of compressor 3 to increase the second preset power based on the current power. No further limitation is made to the second preset power here.

[0074] After reducing the heating power of the heater to slow down the rise of the water level in the water tray 2, the pressure value of the water tray 2 is obtained again after 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 the defrost water drainage speed in the water tray 2 is still not ideal after the heating power of the heater is reduced, resulting in the water level in the water tray 2 still being high. 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 increasing the heat exchange efficiency between the exhaust pipe 31 and the defrost water, and accelerating 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, then controlling the heater to continue operating 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 tray 2 is within a suitable holding range and there is no need to drain it. Therefore, the compressor 3 is stopped to reduce the impact on the defrosting of the evaporator 1. At the same time, since the heater continues to operate based on the operating power after the first preset power is reduced, the water level in the water tray 2 rises at a slower rate, thus preventing the detection result of the pressure detection element 4 from exceeding the first preset pressure value in a short period of time, which would cause the compressor 3 to start and stop frequently.

[0077] Optionally, after controlling the heater to shut down in step S1023, the method further includes:

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

[0079] Step S10232: If the detection result is greater than or equal to the second preset pressure value, then control the compressor 3 to operate at the 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 tray 2 is close to the opening of the water tray 2 and is about to overflow. If the control heater is 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 defrosting water is insufficient to compensate for the rising water level in the water tray 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, in step S103, if the detection result is less than or equal to the first preset pressure value, then when the refrigerator enters the cooling cycle, the compressor 3 is controlled to start, 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, then when the refrigerator enters the cooling cycle, control the compressor 3 to start and run for the first running time.

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

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

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

[0086] Optionally, step S1031, which involves controlling the compressor 3 to start and run for a first running period after the refrigerator enters the cooling cycle, includes:

[0087] Step S10311: When the temperature of the freezer compartment rises to the first preset temperature, control the compressor 3 to start;

[0088] Step S10312: When the temperature of the freezer compartment drops to the second preset temperature, control the compressor 3 to turn off; wherein, the first preset temperature is higher than the second preset temperature.

[0089] The start and stop points 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 turned on. When the temperature of the freezer compartment drops to the second preset temperature, it indicates that the temperature inside the freezer compartment has reached the ideal set temperature, and compressor 3 is turned off to complete the cooling cycle.

[0090] Optionally, step S1032, which involves controlling the compressor 3 to start and run for a second duration after the refrigerator enters the cooling cycle, includes:

[0091] Step S10321: When the temperature of the freezer compartment rises to the third preset temperature, control the compressor 3 to start;

[0092] Step S10322: When the temperature of the freezer compartment drops to the fourth preset temperature, control the compressor 3 to turn off;

[0093] The first preset temperature, the third preset temperature, the fourth preset temperature, and the second preset temperature decrease sequentially.

[0094] It is understandable 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 steps S10311 and S10312, the temperature difference between the start-up point and the stop point of the compressor 3 is greater, and the required cooling time is longer, so that the first running time is greater than the second running time. This allows the compressor 3 to run for a sufficient amount of time to allow all the defrost water to evaporate when the detection result of the pressure detection element 4 is greater than the third preset pressure value and less than or equal to the first preset pressure value, i.e. when there is a lot of defrost water.
