[0047] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," "connected," "in contact," and "connected" should be understood broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; and direct or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0048] In the technology related to clothing processing equipment, when a double-drum clothing processing equipment is drying the double drums, the compressor has been running at a high frequency to meet the heat and dehumidification requirements of the double-drum drying. When the air duct of one drum is closed after drying, the load in the other single-drum drying drum will increase rapidly in a short period of time, causing the load on the compressor and the entire heat pump system to increase rapidly, which can easily cause the compressor to stop and shorten the life of the compressor.

[0049] Based on the above background, the following embodiments are proposed:

[0050] Example 1

[0051] like Figure 1 As shown, this embodiment provides a drying control method for a clothes processing device, the clothes processing device including a first clothes processing drum, a second clothes processing drum and a compressor sharing a drying air duct; the drying control method includes:

[0052] During the process of simultaneously drying the first laundry processing drum and the second laundry processing drum, in response to the first laundry processing drum entering the drying end phase first, controlling the frequency of the compressor of the laundry processing device to decrease to a target frequency;

[0053] When the air inlet temperature of the second laundry processing drum is lower than a preset temperature value, reducing the air volume of the drying air entering the first laundry processing drum through the shared drying air duct;

[0054] According to the working state of the compressor, it is determined whether to stop supplying drying air to the first laundry processing drum through the common drying air duct.

[0055] In this embodiment, during the double-drum drying process, the clothes processing drum that enters the drying end stage first and the clothes processing drum that enters the drying end stage later are distinguished in advance, and then in the process of switching from double-drum drying to single-drum drying, the compressor load is reduced when the first clothes processing drum enters the drying end stage, so that the compressor enters the low-load state in advance, to prevent the compressor and the heat pump system from experiencing large load fluctuations when switching between single and double drums due to excessive load, to ensure stable operation of the compressor and the heat pump system, and to obtain and compare the temperature value of the second clothes processing drum that enters the drying end stage later in advance, so as to keep the temperature value of the second clothes processing drum within a normal range, to avoid the heat load in the second clothes processing drum from rapidly increasing in a short period of time, which causes the heat load of the compressor and the entire heat pump system to rapidly increase. In this process, the drying air intake volume of the first clothes processing drum changes with the second clothes processing drum. The temperature values ​​of the two clothing processing drums are dynamically adjusted. When the temperature value of the second clothing processing drum is relatively high, the air intake volume of the first clothing processing drum can be maintained unchanged, thereby sharing the heat load of the second clothing processing drum and avoiding a sharp increase in the heat load of the second clothing processing drum. When the temperature value of the second clothing processing drum is relatively low, the air intake volume of the first clothing processing drum is controlled to be gradually reduced in a step-by-step manner, further maintaining the temperature value of the second clothing processing drum relatively stable. Then, according to the working status of the compressor, it is determined whether to stop supplying drying air to the first clothing processing drum through the shared drying air duct, further maintaining the normal working status of the compressor itself, and further ensuring the stable operation of the entire heat pump system. This control method maintains the stable operation of the compressor and the entire heat pump system when the clothing processing equipment switches from double-drum drying to single-drum drying, reduces the occurrence of abnormal situations such as compressor shutdown, and correspondingly extends the service life of the compressor.

[0056] Preferably, the timing of entering the drying end stage is determined by whether the time it takes for the first clothing processing drum to reach the drying condition meets the set conditions. For example, by obtaining the time t it takes for the first clothing processing drum to reach the drying condition, the starting point t0 of the time t is the starting point of entering the drying end stage.

[0057] Preferably, the timing of entering the drying end stage is determined based on whether the first clothing processing drum meets the drying condition. For example, the humidity value in the first clothing processing drum is obtained. If the humidity value meets the preset humidity value, the drying condition is met, that is, the drying end stage is entered.

[0058] Preferably, the preset temperature value is 55-75°C or 65°C. The preset temperature value can maintain the heat load of the second laundry processing drum within an acceptable range without affecting the stable operation of the entire heat pump system. At the same time, it does not excessively delay the completion of the drying process of the first laundry processing drum. A preset temperature value that is too low will delay the completion of the drying process of the first laundry processing drum. A preset temperature value that is too high will increase the heat load of the second laundry processing drum, affecting the operation of the compressor and the entire heat pump system.

[0059] Optionally, in an implementation of this embodiment, as Figure 1 As shown, the drying control method of the clothes processing equipment further includes:

[0060] After the frequency of the compressor is controlled to be reduced to the target frequency, the inlet air temperature value of the second laundry processing tub is continuously detected to determine whether the inlet air temperature value of the second laundry processing tub is lower than a preset temperature value.

[0061] In this embodiment, by continuously detecting the inlet air temperature value of the second clothes processing drum to determine whether the inlet air temperature value of the second clothes processing drum is lower than the preset temperature value, the continuous detection is conducive to the dynamic adjustment of the drying air inlet volume of the first clothes processing drum along with the temperature value of the second clothes processing drum. When the temperature value of the second clothes processing drum is relatively large, the inlet air volume of the first clothes processing drum can be maintained unchanged, thereby sharing the load of the second clothes processing drum and avoiding a sharp increase in the heat load of the second clothes processing drum. When the temperature value of the second clothes processing drum is relatively small, the inlet air volume of the first clothes processing drum is controlled to gradually decrease in a step-by-step manner, further maintaining the temperature value of the second clothes processing drum relatively stable.

[0062] Optionally, in an implementation of this embodiment, as Figure 1 As shown,

[0063] Determining whether to stop supplying drying air to the first laundry processing drum through the common drying air duct according to the operating state of the compressor includes:

[0064] Obtain the power value of the compressor. If the power value of the compressor is less than the preset compressor power value within the target time, stop supplying dry air to the first clothing processing drum through the common drying air duct. If the power value of the compressor is detected to be greater than the preset compressor power value within the target time, continue to supply dry air to the first clothing processing drum through the common drying air duct.

[0065] In this embodiment, taking the target time of 5 minutes as an example, within 5 minutes, the compressor power value of the clothing processing equipment is continuously obtained, the power values ​​obtained during this period are averaged, and the average value is compared with the preset compressor power value. The average value of the compressor power during the target time period is compared with the preset compressor power value, which is more accurate and reliable than the instantaneous value. If the average value is less than the preset compressor power value, it proves that the compressor is in a normal working state at this time, and there will be no rapid increase in the heat load of the second clothing processing drum due to high-frequency operation. In this state, the entire heat pump system has a normal working state, and stops supplying drying air to the first clothing processing drum through the common drying air duct, that is, the drying air of the first clothing processing drum is stopped. If the average value is greater than the preset compressor power value, it proves that the compressor is in a high-frequency working state at this time. The high-frequency operation may cause the heat load of the second clothes processing drum to rise rapidly. In this state, the working state of the entire heat pump system is also unstable. In this case, it is chosen to continue to introduce drying air into the first clothes processing drum through the shared drying air duct, so that the first and second clothes processing drums share the compressor load, further avoiding the situation where the load of the second clothes processing drum or the compressor itself rises sharply, maintaining the stable operation of the compressor and the entire heat pump system when the clothes processing equipment switches from double-drum drying to single-drum drying, reducing the occurrence of abnormal situations such as compressor shutdown, and correspondingly extending the service life of the compressor.

[0066] Preferably, the preset compressor frequency value is 550-750 W or 650 W. The limitation of the preset compressor frequency value can further maintain the heat load of the second laundry processing drum within an acceptable range without affecting the stable operation of the entire heat pump system. At the same time, it does not excessively delay the completion of the drying process of the first laundry processing drum. If the preset compressor frequency value is too low, the completion of the drying process of the first laundry processing drum will be delayed. If the preset compressor frequency value is too high, the heat load of the second laundry processing drum will be increased, affecting the operation of the compressor and the entire heat pump system.

[0067] Optionally, in one implementation of this embodiment,

[0068] The clothes processing device has an air outlet connecting the common drying air duct and a first air inlet duct of the first clothes processing drum, and a second air inlet duct connecting the air outlet of the common drying air duct and the second clothes processing drum. An air separation device is provided at the air outlet of the common drying air duct, and the air separation device is used to adjust the degree of connection between the common drying air duct and the first air inlet duct and the second air inlet duct;

[0069] Reducing the volume of drying air passing through the common drying air duct into the first laundry processing drum includes controlling the air separation device to adjust the degree of connectivity between the common drying air duct and the first laundry processing drum from a first connectivity degree to a second connectivity degree less than the first connectivity degree.

[0070] Preferably, the first degree of connectivity is that the air separation device completely connects the common drying duct with the first laundry processing drum, and the second degree of connectivity is that the air separation device connects the common drying duct with the first laundry processing drum by half.

[0071] In this embodiment, the air diversion device is taken as an air diversion valve as an example for explanation. The reduction of the amount of drying air passing into the first clothing processing drum through the common drying air duct can be achieved by fully opening the air diversion valve, so that the common drying air duct and the first clothing processing drum are fully connected, and then converting the air diversion valve to a state where it is half closed, so that the second degree of connection is that the air diversion device connects the common drying air duct and the first clothing processing drum by half, so as to reduce the amount of drying air passing into the first clothing processing drum through the common drying air duct, thereby achieving the purpose of dynamically adjusting the drying air intake volume of the first clothing processing drum according to the temperature value of the second clothing processing drum.

[0072] Optionally, in one implementation of this embodiment,

[0073] The clothes processing device has an air outlet connecting the common drying air duct and a first air inlet duct of the first clothes processing drum, and a second air inlet duct connecting the air outlet of the common drying air duct and the second clothes processing drum. An air separation device is provided at the air outlet of the common drying air duct, and the air separation device is used to adjust the degree of connection between the common drying air duct and the first air inlet duct and the second air inlet duct;

[0074] Continuing to pass the drying air into the first laundry processing drum through the common drying air duct includes: controlling the air distribution device to adjust the degree of connectivity between the common drying air duct and the first laundry processing drum from the third connectivity to a fourth connectivity greater than the third connectivity;

[0075] Stopping the drying air from being introduced into the first laundry processing drum through the common drying air duct includes controlling the air separation device to disconnect the common drying air duct from the first laundry processing drum.

[0076] In this embodiment, the air distribution device is taken as an air distribution valve as an example for explanation. The fourth connectivity degree can be the first connectivity degree in the above embodiment, and the third connectivity degree can be the second connectivity degree in the above embodiment. The fourth connectivity degree adjusted from the third connectivity degree to be greater than the third connectivity degree can be closed by half of the air distribution valve so that the second connectivity degree is the air distribution device connecting the common drying air duct with the first clothing processing drum by half, and converted to a state where the air distribution valve is fully opened so that the common drying air duct is fully connected with the first clothing processing drum, so that the first clothing processing drum and the second clothing processing drum share the heat load, thereby achieving the purpose of dynamically adjusting the drying air intake volume of the first clothing processing drum according to the temperature value of the second clothing processing drum.

[0077] Optionally, in one implementation of this embodiment,

[0078] Controlling the air distribution device to adjust the degree of connectivity between the common drying air duct and the first laundry processing drum from a third degree of connectivity to a fourth degree of connectivity greater than the third degree of connectivity includes:

[0079] The fourth connectivity level is determined based on a difference between the compressor power value and a preset compressor power value, wherein the greater the difference, the greater the difference between the fourth connectivity level and the third connectivity level.

[0080] In this embodiment, the greater the difference between the compressor power value of the laundry processing device and the preset compressor power value, the higher the difference, the more likely the compressor is currently operating at a high frequency. This high frequency operation is more likely to cause a rapid increase in the heat load of the second laundry processing drum, leading to instability in the operation of the entire heat pump system. To further prevent a rapid increase in the load on the second laundry processing drum or the compressor itself, the fourth degree of connectivity is increased to increase the amount of dry air flowing into the first laundry processing drum through the shared drying air duct. This allows the first laundry processing drum to share more of the compressor load with the second laundry processing drum, maintaining stable operation of the compressor and the entire heat pump system during the transition from double-drum drying to single-drum drying, reducing the occurrence of abnormalities such as compressor shutdowns, and correspondingly extending the service life of the compressor. For example, if the third degree of connectivity is halfway closed and the preset compressor power value is 650W, and the average compressor power value is 700W, the difference is 50, and the fourth degree of connectivity can be adjusted to close the air diverter valve by one-third. If the average compressor power value is 800W, the difference is 150, and the fourth degree of connectivity can be adjusted to fully open the air diverter valve.

[0081] Optionally, in one implementation of this embodiment,

[0082] While reducing the air volume of the drying air introduced into the first laundry processing tub through the common drying air duct, the air guiding speed from the inside of the second laundry processing tub to the outside is increased.

[0083] Specifically, increasing the air flow rate from the second laundry processing drum to the outside includes: increasing the speed of the drying fan of the shared drying air duct

[0084] In this embodiment, the speed of the drying fan is increased to increase the rate at which the second clothing processing drum guides air outward, thereby further maintaining the temperature in the second clothing processing drum at a high air guide rate when the air intake of the first clothing processing drum decreases, thereby effectively reducing the heat fluctuation amplitude of the compressor and the heat pump system.

[0085] Example 2

[0122] <Blower 61 and Two-device Assembly 62>

[0123] like Figures 2 to 4 As shown, the fan 61 and the two-device assembly 62 are arranged between the first outer cylinder and the second outer cylinder. A first main air inlet is formed on the side of the first air distribution housing close to the two-device assembly 62, and a second main air inlet is formed on the side of the second air distribution housing close to the fan 61. The second main air inlet, the fan 61, the two-device assembly 62 and the first main air inlet are connected in sequence. The fan 61 is used to provide power to the drying airflow.

[0124] Specifically, the first outer drum, the first air outlet 53, the second air branch cavity, the fan 61, the two-device assembly 62, the first air branch cavity and the first air inlet 51 are connected in sequence to form a first drying air flow circuit. When the air inlet baffle opens the first upper branch air outlet and the air outlet baffle opens the second upper branch air outlet, the first drying air flow circuit is connected, and the first clothes processing drum can be dried; the second outer drum, the second air outlet 54, the second air branch cavity, the fan 61, the two-device assembly 62, the first air branch cavity and the second air inlet 52 are connected in sequence to form a second drying air flow circuit.

[0125] Furthermore, the two-device assembly 62 includes two device boxes, in which two devices are disposed. The two device boxes are formed with two device box inlets and two device box outlets disposed opposite to each other. The two devices include an evaporator and a condenser. The evaporator is used to dehumidify the dry air flow, and the condenser is used to heat the dry air flow. The fan 61 is formed with a fan cavity. The fan cavity has a fan inlet formed in the axial direction and a fan outlet formed in the radial direction.

[0126] The fan inlet is connected to the second main air outlet, the fan outlet is connected to the two-device box inlet, and the two-device box outlet is connected to the first main air outlet; preferably, the air inlet device, the two-device assembly 62, the fan 61 and the air outlet device form an H-shaped structure.

[0127] The air inlet baffle and the air outlet baffle are controlled to move, so that any clothes processing drum can be dried separately or multiple clothes processing drums can be dried at the same time; at the same time, the flow rate of the drying airflow entering any clothes processing drum and the flow rate of the drying airflow discharged from any clothes processing drum can be adjusted; specifically, when the first upper air outlet is in the open state, the air inlet baffle is rotated to adjust the opening size of the first upper air outlet, thereby adjusting the flow rate of the drying airflow entering the first clothes processing drum; when the first lower air outlet is in the open state, the air inlet baffle is rotated to adjust the opening size of the first lower air outlet, thereby adjusting the flow rate of the drying airflow entering the second clothes processing drum.

[0128] In the double-drum drying process of the clothes processing equipment, the clothes processing drum that enters the drying end stage first and the clothes processing drum that enters the drying end stage later are distinguished in advance, and then in the process of switching from double-drum drying to single-drum drying, the compressor load is reduced when the first clothes processing drum 11 enters the drying end stage, so that the compressor enters the low-load state in advance, and prevents the compressor and the heat pump system from experiencing large load fluctuations when switching between single and double drums due to excessive load, ensuring stable operation of the compressor and the heat pump system, and obtaining and comparing the temperature value of the second clothes processing drum 12 that enters the drying end stage later in advance, so as to keep the temperature value of the second clothes processing drum 12 within a normal range, and avoid the heat load in the second clothes processing drum 12 from rapidly increasing in a short period of time, which causes the heat load of the compressor and the entire heat pump system to rapidly increase. In this process, the drying air intake of the first clothes processing drum 11 follows the drying air intake of the second clothes processing drum 11. The temperature value of the processing drum 12 is dynamically adjusted, and the air intake volume of the first clothing processing drum 11 can be maintained unchanged when the temperature value of the second clothing processing drum 12 is relatively large, thereby sharing the heat load of the second clothing processing drum 12 and avoiding a sharp increase in the heat load of the second clothing processing drum 12. When the temperature value of the second clothing processing drum 12 is relatively small, the air intake volume of the first clothing processing drum 11 is controlled to be gradually reduced in a step-by-step manner, further maintaining the temperature value of the second clothing processing drum 12 relatively stable, and then determining whether to stop supplying drying air to the first clothing processing drum 11 through the shared drying air duct according to the working state of the compressor, further maintaining the normal working state of the compressor itself, and further ensuring the stable operation of the entire heat pump system. This control method maintains the stable operation of the compressor and the entire heat pump system when the clothing processing equipment switches from double-drum drying to single-drum drying, reduces the occurrence of abnormal situations such as compressor shutdown, and correspondingly extends the service life of the compressor.

[0129] In summary, the ingenious conception of the drying control method for clothes processing equipment lies in:

[0130] First, in the double-drum drying process, the clothes processing drum that enters the drying end stage first and the clothes processing drum that enters the drying end stage later are distinguished in advance, and then in the process of switching from double-drum drying to single-drum drying, the compressor load is reduced when the first clothes processing drum enters the drying end stage, so that the compressor enters the low-load state in advance, preventing the compressor and the heat pump system from experiencing large load fluctuations when switching between single and double drums due to excessive load, ensuring stable operation of the compressor and the heat pump system, and obtaining and comparing the temperature value of the second clothes processing drum that enters the drying end stage later in advance, so as to keep the temperature value of the second clothes processing drum within a normal range, and avoid the heat load in the second clothes processing drum from rapidly increasing in a short period of time, causing the compressor to The heat load of the entire heat pump system increases rapidly, and at the same time, the drying air intake volume of the first clothing processing drum is dynamically adjusted with the temperature value of the second clothing processing drum. When the temperature value of the second clothing processing drum is relatively high, the air intake volume of the first clothing processing drum can be maintained unchanged, thereby sharing the heat load of the second clothing processing drum and avoiding a sharp increase in the heat load of the second clothing processing drum. When the temperature value of the second clothing processing drum is relatively low, the air intake volume of the first clothing processing drum is controlled to gradually decrease in a step-by-step manner, further maintaining the temperature value of the second clothing processing drum relatively stable, and then determining whether to stop supplying drying air to the first clothing processing drum through the shared drying air duct according to the working status of the compressor, further maintaining the normal working status of the compressor itself, and further ensuring the stable operation of the entire heat pump system.

[0131] Secondly, the average value of the compressor power within the target time period is compared with the preset compressor power value, which is more accurate and reliable than the instantaneous value. If the average value is less than the preset compressor power value, the drying air is stopped from being introduced into the first clothing processing drum through the common drying air duct. If the average value is greater than the preset compressor power value, the drying air is continued to be introduced into the first clothing processing drum through the common drying air duct, so that the first clothing processing drum and the second clothing processing drum share the compressor load, further avoiding the situation where the load of the second clothing processing drum or the compressor itself increases sharply, maintaining the stable operation of the compressor and the entire heat pump system when the clothing processing equipment switches from double-drum drying to single-drum drying, reducing the occurrence of abnormal situations such as compressor shutdown, and correspondingly extending the service life of the compressor.

[0132] Third, the preset temperature value and the preset compressor frequency value are designed to maintain the heat load of the second laundry treatment drum within an acceptable range without affecting the stable operation of the entire heat pump system and without excessively delaying the completion of the drying process of the first laundry treatment drum.

[0133] Fourth, the fourth connectivity level is determined based on the difference between the compressor power value of the clothing processing equipment and the preset compressor power value. The larger the difference, the greater the gap between the fourth connectivity level and the third connectivity level, which can more accurately and effectively maintain the relative stability of the temperature value of the second clothing processing drum.
