[0056] The technical solution of this embodiment is described in detail below in conjunction with the accompanying drawings. The following embodiments and examples can be combined with each other if there is no conflict.

[0057] Embodiment 1

[0058] This embodiment provides a clothes processing device with a drying function. The clothes processing device of this embodiment may have only a drying function or may have both a drying function and a washing function. Figure 1 As shown, the laundry processing device includes a laundry processing drum 1, an air duct assembly, a main fan 21, an auxiliary fan 22, a heat pump system and a control device. Among them:

[0059] A shell cavity is formed in the shell, and a clothing treatment drum 1 is arranged in the shell cavity, and the clothing treatment drum 1 is provided with a first air inlet, a second air inlet and an air outlet. The arrangement positions of the first air inlet, the second air inlet and the air outlet are not clearly defined. In one example, a door seal is provided at the tube mouth of the clothing treatment drum 1, and the first air inlet and the second air outlet are both arranged at the door seal. The air outlet is provided at the bottom of the clothing treatment drum 1, so that a longer air flow path is formed between the first air inlet and the air outlet, and the air flow can penetrate the clothes, thereby ensuring a uniform drying effect on the clothes. In other achievable methods, the first air inlet and the second air inlet are arranged at different positions in the axial direction of the clothing treatment drum 1 to deliver air flow to different positions in the clothing treatment drum 1, which can also improve the drying effect of the clothes.

[0060] The air duct assembly is arranged in the space between the housing and the clothing treatment drum 1, preferably arranged above the clothing treatment drum 1. The air duct assembly includes a main air duct 31 and an auxiliary air duct 32, the main air duct 31 connects the first air inlet and the air outlet, and the auxiliary air duct 32 connects the second air inlet with the external environment. The main fan 21 and the auxiliary fan 22 are respectively arranged in the main air duct 31 and the auxiliary air duct 32, the main fan 21 can drive the airflow to circulate between the main air duct 31 and the clothing treatment drum 1, the auxiliary fan 22 can introduce the airflow in the external environment into the clothing treatment drum 1 through the auxiliary air duct 32, and can also discharge the moisture in the clothing treatment drum 1 to the external environment through the auxiliary air duct 32, and the auxiliary fan 22 is a variable frequency fan. In a preferred embodiment, the main fan 21 and the auxiliary fan 22 are both variable frequency fans.

[0061] The heat pump system is used to dehumidify the airflow in the main air duct 31. The heat pump system includes a compressor and two-device components. The compressor is arranged outside the clothing treatment tub 1, for example, in the space between the bottom of the clothing treatment tub 1 and the shell. The two-device components are arranged in the main air duct 31 and are located between the air outlet end of the main fan 21 and the first air inlet. The two-device components include an evaporator 4 and a condenser 5. Along the airflow direction, the condenser 5 is located downstream of the evaporator 4. The exhaust end of the compressor is connected to the condenser 5, and the suction end of the compressor is connected to the evaporator 4.

[0062] The clothing processing device also includes a throttling device, wherein the compressor, the condenser 5, the throttling device and the evaporator 4 are connected by a refrigerant pipeline to form a refrigerant circulation loop. Under the action of the main fan 21, the hot and humid airflow entering the main air duct 31 from the first air outlet is blown toward the evaporator 4, and forms dry cold air after absorbing heat in the evaporator 4. The dry cold air flows through the condenser 5 to be heated to form a high-temperature airflow, and the high-temperature airflow finally enters the clothing processing drum 1 through the first air inlet to dry the clothes in the clothing processing drum 1. This embodiment adopts a heat pump drying method to achieve higher drying efficiency and better drying effect.

[0063] The control device is configured to control the temperature and / or humidity in the laundry treatment drum by controlling the operating frequency of the compressor and the fan frequency of the auxiliary fan, or to adjust the fan frequency of the auxiliary fan according to the working state of the condenser.

[0064] During the clothes drying process, after the compressor is started, the temperatures of the compressor and the condenser tubes will rise rapidly in a short period of time, but the temperature in the clothes processing drum will rise slowly. In order to avoid overload protection during the temperature rising process in the drum due to high-frequency operation of the compressor, the temperature and / or humidity in the clothes processing drum can be controlled by coordinating the operating frequency of the compressor and the fan frequency of the auxiliary fan, or by adjusting the fan frequency of the auxiliary fan according to the working state of the condenser to reduce the load of the compressor during the temperature rising process, thereby reducing or even avoiding the problem of frequent shutdown of the compressor during the temperature rising process, wherein the working state of the condenser includes the condenser tube temperature.

[0065] In an optional embodiment, the control device is configured to control the temperature and / or humidity in the clothing processing drum by controlling the fan frequency of the auxiliary fan when the compressor is running at a target frequency, wherein the target frequency is the frequency at which the compressor runs at high frequency, and preferably the target frequency is the maximum frequency at which the compressor runs normally.

[0066] This embodiment can reduce the load of the high-frequency operation of the compressor, thereby maintaining the high-frequency operation state of the compressor, reducing the risk of the compressor shutting down due to continuous high-frequency operation, improving the dehumidification efficiency of the heat pump system, and improving the performance of the high-frequency operation of the heat pump system.

[0067] In an implementable manner, the laundry processing device comprises a first temperature detection device, the first temperature detection device is used to detect the temperature of the condenser tube. The control device is configured to control the fan frequency of the auxiliary fan according to the temperature of the condenser tube.

[0068] Since the auxiliary fan can be turned on during the high-frequency operation of the compressor to introduce fresh air from the external environment into the laundry treatment drum, the fresh air will enter the main air duct through the air outlet after entering the laundry treatment drum, and will be blown to the evaporator and condenser in sequence under the action of the main fan, so as to achieve the effect of cooling the heat pump system, thereby reducing the load of the compressor. As the condensing temperature increases, in order to avoid an increase in the load of the compressor and maintain the cooling effect on the compressor, it is necessary to control the auxiliary fan to introduce a gradually increasing amount of fresh air. Therefore, this embodiment can effectively avoid frequent shutdowns of the compressor due to overload by regulating the fan frequency of the auxiliary fan 22 according to the condenser tube temperature.

[0069] In one example, the control device is further configured to control the fan frequency of the auxiliary fan 22 to increase as the condenser tube temperature increases when the condenser tube temperature is within a preset temperature range. This is because the higher the condenser tube temperature, the higher the temperature of the hot air entering the laundry treatment tub 1 from the first air inlet, so it is necessary to increase the air flow from the outside environment into the laundry treatment tub 1 by increasing the fan frequency of the auxiliary fan 22 to avoid overload protection of the compressor. On the contrary, the lower the condenser tube temperature, the lower the temperature of the hot air entering the laundry treatment tub 1 from the first air inlet, so it is necessary to reduce the air flow from the outside environment into the laundry treatment tub 1 by reducing the fan frequency of the auxiliary fan 22 to reduce energy consumption.

[0070] When the condenser tube temperature is lower than the minimum value of the preset temperature range, it indicates that the temperature in the laundry processing drum 1 is at a relatively low level. In this case, the auxiliary fan 22 is controlled to be turned off, and the rate of increase of the temperature in the laundry processing drum 1 is accelerated only by high-frequency operation of the compressor.

[0071] When the condenser tube temperature is greater than the maximum value of the preset temperature range, it means that the compressor load cannot be reduced even if the auxiliary fan is running at the highest fan frequency. In order to avoid the compressor overload protection, the compressor needs to be controlled to operate at a reduced frequency. Since the condensing temperature will be lowered after the compressor operates at a reduced frequency, in order to avoid continuing to introduce fresh air and causing the temperature in the clothing processing drum 1 to be too low, the auxiliary fan needs to be controlled to be turned off, thereby reducing energy consumption.

[0072] In a preferred embodiment, the clothing processing device further includes a third temperature detection device, which is used to detect the evaporator outlet air temperature. When the condenser tube temperature is in a preset temperature range, the control device is further configured to further control the auxiliary fan frequency according to the difference between the condenser tube temperature and the evaporator outlet air temperature. Specifically, when the difference between the condenser tube temperature and the evaporator outlet air temperature is greater than the set temperature difference, the compressor frequency is further increased. This is because the greater the difference between the condenser tube temperature and the evaporator outlet air temperature, the slower the temperature rise in the barrel. At this time, the auxiliary fan frequency can be further increased to reduce the compressor load.

[0073] In one implementable embodiment, the clothing processing device also includes a second temperature detection device and a third temperature detection device, the second temperature detection device is used to detect the inlet air temperature of the first air inlet, and the third temperature detection device is used to detect the outlet air temperature of the air outlet; the control device is also configured to control the start-up state and / or fan frequency of the auxiliary fan according to the inlet air temperature and the outlet air temperature during the clothing drying process.

[0074] Since the dehumidification efficiency of the heat pump drying system is low in the later stage of drying, the drying stage can be determined according to the inlet air temperature and the outlet air temperature, and then the dehumidification can be directly removed by controlling the start-up of the auxiliary fan in the later stage of drying, thereby achieving the effect of improving the dehumidification efficiency.

[0075] Specifically, the control device is also configured as follows: when the temperature difference between the inlet air temperature and the outlet air temperature is less than or equal to the set temperature difference, and the inlet air temperature reaches the first set temperature, it means that at this time, in the late stage of drying, the dehumidification efficiency of the heat pump system is low. At this time, the auxiliary fan is controlled to start and discharge the moisture in the clothing treatment drum to the external environment through the auxiliary air duct, and the operating frequency of the auxiliary fan is controlled according to the inlet air temperature. The fan frequency when the auxiliary fan is just started is the first frequency. Since the introduction of direct dehumidification will have a significant impact on the temperature in the drum, therefore, when the inlet air temperature is detected to be lower than the second set temperature, the auxiliary fan is controlled to operate at the second fan frequency to avoid excessive reduction in the temperature in the drum and affect the drying effect. The first set temperature> the second set temperature, the first fan frequency> the second fan frequency, and the temperature difference is set to 12°C~15°C. The second set temperature=the first set temperature-5°C.
