[0048] In related technologies, during the drying process of heat pump drying equipment, the compressor temperature continuously rises, reaching the compressor's frequency limiting temperature or even the shutdown temperature. This forces the compressor to reduce its frequency or shut down, significantly reducing drying efficiency and preventing the full utilization of the advantages of the heat pump system, thus lowering the drying efficiency.

[0049] To address the above technical problems, this embodiment proposes a clothing processing device and drying method with a drying function, wherein the clothing processing device includes:

[0050] The garment processing drum is equipped with a first air inlet, a second air inlet, and an air outlet.

[0051] The air duct assembly includes a main air duct and an auxiliary air duct. The main air duct connects the first air inlet and the air outlet, and the auxiliary air duct connects the second air inlet to the external environment.

[0052] The main fan and the auxiliary fan are located in the main air duct. The main fan can drive the airflow to circulate between the main air duct and the clothes processing drum. The auxiliary fan is located in the auxiliary air duct. The auxiliary fan can introduce the airflow from the outside environment into the clothes processing drum through the auxiliary air duct, and can also discharge the moisture in the clothes processing drum to the outside environment through the auxiliary air duct. The auxiliary fan is a variable frequency fan.

[0053] A heat pump system is used to dehumidify the airflow in the main air duct. The heat pump system includes a compressor and a two-phase assembly. The compressor is located outside the clothes handling drum, and the two-phase assembly is located inside the main air duct. The two-phase assembly includes an evaporator and a condenser.

[0056] The technical solution of this embodiment will be described in detail below with reference to the accompanying drawings. In the absence of conflict, the following embodiments and examples can be combined with each other.

[0057] Example 1

[0058] This embodiment proposes a clothing processing device with a drying function. This clothing processing device may have only a drying function, or it may have both drying and washing functions simultaneously. Figure 1 As shown, the garment processing equipment includes a garment 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 cavity is formed within the housing, and a clothes processing drum 1 is housed within the cavity. The clothes processing drum 1 has a first air inlet, a second air inlet, and an air outlet. The positions of the first air inlet, the second air inlet, and the air outlet are not specifically defined. In one example, a door seal is provided at the opening of the clothes processing drum 1, and both the first air inlet and the second air outlet are located at the door seal. The air outlet is located at the bottom of the clothes processing drum 1, thus forming a long airflow path between the first air inlet and the air outlet, allowing the airflow to penetrate the clothes and ensuring a uniform drying effect. In other possible implementations, the first air inlet and the second air inlet are located at different positions along the axial direction of the clothes processing drum 1 to deliver airflow to different locations within the clothes processing drum 1, which also improves the drying effect of the clothes.

[0060] The air duct assembly is disposed in the space between the housing and the clothing processing drum 1, preferably above the clothing processing 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 to the external environment. The main fan 21 and the auxiliary fan 22 are respectively disposed 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 processing drum 1. The auxiliary fan 22 can introduce airflow from the external environment into the clothing processing drum 1 through the auxiliary air duct 32, and can also exhaust moisture in the clothing processing drum 1 to the external environment through the auxiliary air duct 32. The auxiliary fan 22 is a variable frequency fan. In a preferred embodiment, both the main fan 21 and the auxiliary fan 22 are variable frequency fans.

[0061] The heat pump system is used to dehumidify the airflow within the main air duct 31. The heat pump system includes a compressor and a heat exchanger assembly. The compressor is located outside the clothes handling drum 1, for example, in the space between the bottom of the clothes handling drum 1 and the casing. The heat exchanger assembly is located within the main air duct 31, between the outlet of the main fan 21 and the first air inlet. The heat exchanger assembly includes an evaporator 4 and a condenser 5. Along the airflow direction, the condenser 5 is located downstream of the evaporator 4. The compressor's discharge end is connected to the condenser 5, and the compressor's suction end is connected to the evaporator 4.

[0062] The garment processing equipment also includes a throttling device, wherein the compressor, condenser 5, throttling device, and evaporator 4 are connected by refrigerant pipelines 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. After absorbing heat in the evaporator 4, it forms dry and cold air. The dry and cold air flows through the condenser 5 and is heated to form a high-temperature airflow. The high-temperature airflow finally enters the garment processing drum 1 through the first air inlet to dry the clothes in the garment processing drum 1. This embodiment uses a heat pump drying method, which can achieve high drying efficiency and good drying effect.

[0063] The control device is configured to control the temperature and / or humidity inside the garment processing drum by controlling the operating frequency of the compressor and the fan frequency of the auxiliary fan, or is configured to adjust the fan frequency of the auxiliary fan according to the operating status of the condenser.

[0064] During the clothes drying process, after the compressor starts, the temperature of the compressor and condenser tubes rises rapidly in a short period of time, but the temperature inside the clothes drying drum rises more slowly. To avoid overload protection during the drum's temperature rise due to the high-frequency operation of the compressor, the temperature and / or humidity inside the clothes drying drum can be controlled by coordinating the operation frequency of the compressor and the fan frequency of the auxiliary fan. Alternatively, the fan frequency of the auxiliary fan can be adjusted according to the working status of the condenser to reduce the load on the compressor during the temperature rise process. This can reduce or even avoid the problem of frequent compressor shutdowns during the temperature rise process. The working status of the condenser includes the condenser tube temperature.

[0065] In one alternative embodiment, the control device is configured to control the temperature and / or humidity inside the garment processing drum by controlling the fan frequency of the auxiliary fan when the compressor is operating at a target frequency, wherein the target frequency is the frequency at which the compressor operates at high frequency, preferably the highest frequency at which the compressor operates normally.

[0066] This embodiment can reduce the load on the compressor during high-frequency operation, thereby maintaining the compressor's high-frequency operation, reducing the risk of compressor shutdown due to continuous high-frequency operation, improving the dehumidification efficiency of the heat pump system, and enhancing the performance of the heat pump system during high-frequency operation.

[0067] In one possible implementation, the garment handling equipment includes a first temperature detection device for detecting the condenser tube temperature. A control device is configured to control the fan frequency of an auxiliary fan based on the condenser tube temperature.

[0068] During high-frequency compressor operation, the auxiliary fan can be activated to introduce fresh air from the outside environment into the clothes handling drum. This fresh air then enters the main air duct through the air outlet and, under the action of the main fan, is sequentially blown onto the evaporator and condenser, achieving a cooling effect on the heat pump system and thus reducing the compressor load. As the condensing temperature rises, to avoid increasing the compressor load and maintain the cooling effect on the compressor, the amount of fresh air introduced by the auxiliary fan needs to be gradually increased. Therefore, this embodiment effectively avoids frequent compressor shutdowns due to overload by adjusting the fan frequency of the auxiliary fan 22 according to the condenser pipe temperature.

[0069] In one example, the control device is also configured to increase the fan frequency of the auxiliary fan 22 as the condenser tube temperature rises, provided the condenser tube temperature is within a preset temperature range. This is because a higher condenser tube temperature results in a higher temperature of the hot air entering the clothes handling drum 1 through the first air inlet. Therefore, increasing the fan frequency of the auxiliary fan 22 increases the airflow from the external environment into the clothes handling drum 1 to prevent the compressor from overloading. Conversely, a lower condenser tube temperature results in a lower temperature of the hot air entering the clothes handling drum 1 through the first air inlet. Therefore, decreasing the fan frequency of the auxiliary fan 22 reduces the airflow from the external environment into the clothes handling drum 1 to lower energy consumption.

[0070] If the condenser tube temperature is lower than the minimum value of the preset temperature range, it indicates that the temperature inside the clothes processing drum 1 is at a low level. At this time, the auxiliary fan 22 is turned off, and the temperature inside the clothes processing drum 1 is increased by the high-frequency operation of the compressor.

[0071] If the condenser tube temperature is greater than the maximum value of the preset temperature range, it means that even if the auxiliary fan is running at the highest fan frequency, the compressor load cannot be reduced. In order to avoid the compressor overload protection, the compressor needs to be controlled to run at a reduced frequency. Since the compressor will run at a reduced frequency, the condensing temperature will decrease. In order to avoid the temperature inside the clothes handling drum 1 becoming too low due to the continued intake of fresh air, the auxiliary fan needs to be turned off, which will also reduce energy consumption.

[0072] In a preferred embodiment, the garment processing equipment further includes a third temperature detection device for detecting the evaporator outlet temperature. When the condenser tube temperature is within a preset temperature range, the control device is further configured to control the auxiliary fan frequency based on the difference between the condenser tube temperature and the evaporator outlet temperature. Specifically, the compressor frequency is further increased when the difference between the condenser tube temperature and the evaporator outlet temperature is greater than a set temperature difference. This is because a larger difference between the condenser tube temperature and the evaporator outlet temperature indicates a slower temperature rise inside the drum, allowing for a further increase in the auxiliary fan frequency to reduce the compressor load.

[0073] In one possible implementation, the garment processing equipment further includes a second temperature detection device and a third temperature detection device, the second temperature detection device being used to detect the inlet air temperature of the first air inlet and the third temperature detection device being used to detect the outlet air temperature; the control device is also configured to control the start-up status and / or fan frequency of the auxiliary fan based on the inlet air temperature and the outlet air temperature during the garment 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. In this way, the dehumidification can be directly removed by controlling the start of the auxiliary fan in the later stage of drying, thereby improving the dehumidification efficiency.

[0075] Specifically, the control device is further configured to: when the temperature difference between the inlet and outlet air temperatures is less than or equal to the set temperature difference, and the inlet air temperature reaches the first set temperature, it indicates that the heat pump system's dehumidification efficiency is low during the later stages of drying. At this time, the auxiliary fan is activated to exhaust the moisture in the clothes processing 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 at the initial startup of the auxiliary fan is the first frequency. Since the introduction of direct exhaust dehumidification will significantly affect the temperature inside the drum, when the detected inlet air temperature is lower than the second set temperature, the auxiliary fan is controlled to operate at the second fan frequency to avoid excessive temperature drop inside the drum, which would affect the drying effect. The first set temperature > the second set temperature, and the first fan frequency > the second fan frequency. For example, the set temperature difference is 12℃~15℃. The second set temperature = the first set temperature - 5℃.
