[0054] 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.

[0055] Embodiment 1

[0056] like Figure 1 - Figure 4As shown, this embodiment proposes a clothes processing device with a drying function. The clothes processing device of this embodiment can have only a drying function, or can have both a drying function and a washing function. The clothes processing device includes a housing, a clothes processing drum 1, an air duct assembly, a heat pump system, a first filter screen, a second filter screen, and a control device. Among them:

[0057] A shell cavity is formed in the shell, and a clothes treatment drum 1 is arranged in the shell cavity, and the clothes treatment drum 1 is provided with an air inlet, a first air outlet, and a second air outlet. The arrangement positions of the air inlet, the first air outlet, and the second air outlet are not clearly defined. In one example, a door seal is arranged at the drum mouth of the clothes treatment drum 1, the air inlet is arranged at the door seal, and the first air outlet and the second air outlet are opened at the drum bottom of the clothes treatment drum 1, so that a long air flow path is formed between the air inlet and the first air outlet and the second air outlet, and the air flow can penetrate the clothes, thereby ensuring a uniform drying effect on the clothes.

[0058] The air duct assembly is arranged in the space between the housing and the laundry treatment drum 1, preferably arranged above the laundry treatment drum 1. The air duct assembly includes a main air duct 31, an auxiliary air duct 32, a main fan 21 and an auxiliary fan 22. The main air duct 31 connects the first air inlet and the first air outlet, the auxiliary air duct 32 connects the second air inlet and the second air outlet, the main fan 21 is arranged in the main air duct 31, the auxiliary fan 22 is arranged in the auxiliary air duct 32, and a circulating air path is formed between the laundry treatment drum 1 and the main air duct 31, and between the laundry treatment drum 1 and the auxiliary air duct 32. The rotation direction of the main fan 21 and the auxiliary fan 22 can be changed as needed.

[0059] The clothes treatment drum 1 of this embodiment may have only one air inlet, and the air outlet ends of the main air duct 31 and the auxiliary air duct 32 are both connected to the air inlet. In a preferred embodiment, the clothes treatment drum 1 has two air inlets, and the air outlet ends of the main air duct 31 and the auxiliary air duct 32 are connected to the two air inlets in a one-to-one correspondence to increase the air intake of the clothes treatment drum 1. The two inlets may be both provided at the door seal of the clothes treatment drum 1, or may be provided at different positions in the axial direction of the clothes treatment drum 1 to deliver airflow to different positions in the clothes treatment drum 1, which can also improve the drying effect of clothes.

[0060] The heat pump system includes a first refrigerant circulation flow path and a second refrigerant circulation flow path with variable refrigerant flow directions. The first refrigerant circulation flow path can heat and dehumidify the airflow in the main air duct 31, and the second refrigerant circulation flow path can heat and dehumidify the airflow in the auxiliary air duct 32. Wherein: the flow directions of the first refrigerant circulation flow path and the second refrigerant circulation flow path can be changed as needed. The first refrigerant circulation flow path and the second refrigerant circulation flow path both include a compressor 9, a reversing device, a condenser, a throttling device and an evaporator connected in sequence through a refrigerant pipeline. The first refrigerant circulation flow path and the second refrigerant circulation flow path can have their own independent compressor 9, reversing device, condenser, throttling device and evaporator, and the first refrigerant circulation flow path and the second refrigerant circulation flow path can also share a compressor 9 and a reversing device.

[0061] Preferably, the heat pump system includes a compressor 9, a reversing device, a first heat exchanger 51, a second heat exchanger 41, a third heat exchanger 52 and a fourth heat exchanger 42. The first heat exchanger 51 and the second heat exchanger 41 are arranged in the main air duct 31, and the first heat exchanger 51 is arranged close to the air inlet. The third heat exchanger 52 and the fourth heat exchanger 42 are arranged in the auxiliary air duct 32, and the third heat exchanger 52 is arranged close to the air inlet. The compressor 9, the reversing device, the first heat exchanger 51 and the second heat exchanger 41 are connected through a refrigerant pipeline to form a first refrigerant circulation flow path, and the compressor 9, the reversing device, the third heat exchanger 52 and the fourth heat exchanger 42 are connected through a refrigerant pipeline to form a second refrigerant circulation flow path. During the drying process, the refrigerant in the first refrigerant circulation flow path flows from the second heat exchanger 41 to the first heat exchanger 51, that is, the second heat exchanger 41 serves as an evaporator and the first heat exchanger 51 serves as a condenser; the refrigerant in the second refrigerant circulation flow path flows from the fourth heat exchanger 42 to the third heat exchanger 52, that is, the fourth heat exchanger 42 serves as an evaporator and the third heat exchanger 52 serves as a condenser.

[0062] The heat pump system of this embodiment can reduce production costs and the space occupied by the heat pump system while achieving heating and dehumidification of the airflow in the main air duct 31 and the auxiliary air duct 32.

[0063] The first filter covers the first air outlet and is used to filter the airflow entering the main air duct 31, and the second filter covers the second air outlet and is used to filter the airflow entering the auxiliary air duct 32. The control device is configured to control the heat pump system to be in a startup state during the filter cleaning process, and control the rotation direction of the main fan 21 and the auxiliary fan 22 according to the dirtiness and blockage of the first filter and the second filter, and control the refrigerant flow direction of the first refrigerant circulation flow path and the second refrigerant circulation flow path.

[0064] Specifically, Figure 2 As shown, when the first filter is clogged, the control device controls the heat pump system to be in the start-up state, and controls the air outlet direction of the main fan 21 to be toward the first filter (the air flow direction refers to Figure 2The refrigerant flow direction of the first refrigerant circulation path is controlled to be a refrigerant flow direction that enables the main fan 21 to blow hot air to the first filter, that is, by controlling the reversing device so that the refrigerant in the first refrigerant circulation path flows from the first heat exchanger 51 to the second heat exchanger 41. At this time, the first heat exchanger 51 serves as an evaporator and the second heat exchanger 41 serves as a condenser.

[0065] When the second filter is clogged with dirt, the control device controls the heat pump system to be in the start-up state, controls the air outlet direction of the auxiliary fan 22 to be toward the second filter, and controls the refrigerant flow direction of the second refrigerant circulation path to be a refrigerant flow direction that enables the auxiliary fan 22 to blow hot air toward the second filter, that is, by controlling the reversing device so that the refrigerant in the second refrigerant circulation path flows from the third heat exchanger 52 to the fourth heat exchanger 42. At this time, the third heat exchanger 52 acts as an evaporator and the fourth heat exchanger 42 acts as a condenser.

[0066] like Figure 3 As shown, when the first filter and the second filter are both dirty and clogged, the control device controls the heat pump system to be in the start-up state, controls the air outlet direction of the main fan 21 to be toward the first filter, and controls the air outlet direction of the auxiliary fan 22 to be toward the second filter (the air flow direction refers to Figure 3 The refrigerant flow direction of the first refrigerant circulation flow path is controlled to enable the main fan 21 to blow hot air to the first filter, and the refrigerant flow direction of the second refrigerant circulation flow path is controlled to enable the auxiliary fan 22 to blow hot air to the second filter.

[0067] The clothing processing device of this embodiment is provided with a heat pump system having a first refrigerant circulation flow path and a second refrigerant circulation flow path. While achieving heating and dehumidification of the air flow distribution in the main air duct 31 and the auxiliary air duct 32, it can also coordinately regulate the flow direction of the first refrigerant circulation flow path and the second refrigerant circulation flow path, and the rotation direction of the main fan 21 and the auxiliary fan 22 when the first filter and / or the second filter is dirty and clogged, so as to blow hot air towards the dirty and clogged filter to accelerate the removal of hair debris from the surface of the filter. At the same time, if the dirty and clogged filter is sprayed and cleaned in advance, blowing hot air towards the dirty and clogged filter can also accelerate the evaporation rate of the water film, thereby significantly improving the cleaning effect of the filter.

[0068] Further preferably, Figure 4 As shown in the figure, when one of the first filter screen and the second filter screen is clogged with dirt, the control device further controls the air outlet direction of the fan corresponding to the dirty and clogged filter screen to be toward the dirty and clogged filter screen, and controls the air outlet direction of the fan corresponding to the undirty and clogged filter screen to be toward the air inlet. At this time, a short-circuited circulating air path is formed between the main air duct 31 and the auxiliary air duct 32 (the airflow direction refers to Figure 4The airflow is directed in the direction indicated by the arrow in the middle, thereby improving the circulation efficiency of the airflow between the main air duct 31 and the auxiliary air duct 32, improving the efficiency of removing hair debris from the dirty and blocked filter, and accelerating the removal of the water film when there is a water film on the filter, further improving the cleaning effect of the filter. In addition, this embodiment can also efficiently clean the filter during the drying process without affecting the normal drying process.

[0069] There is no limitation on the method for determining the dirtiness and blockage conditions of the first filter screen and the second filter screen in this embodiment.

[0070] In one example, after receiving the user's filter cleaning instruction, it is determined based on the cumulative number of times the filter has been dried since the last filter cleaning. For example, if the cumulative number of times the filter has been dried since the last filter cleaning is less than the set number, it is determined that the filter is lightly clogged and does not need to be cleaned; if the cumulative number of times the filter has been dried since the last filter cleaning is greater than the set number, it is determined that the filter is heavily clogged and needs to be cleaned.

[0071] In another example, the clothing processing device further includes a first dirty blockage detection device and a second dirty blockage detection device, wherein the first dirty blockage detection device is used to detect the dirty blockage condition of the first filter, and the second dirty blockage detection device is used to detect the dirty blockage condition of the second filter. In this embodiment, the dirty blockage condition of the first filter and the second filter can be accurately detected by setting the first dirty blockage detection device and the second dirty blockage detection device, thereby achieving targeted cleaning of the first filter and the second filter. Among them, the manner in which the first dirty blockage detection device and the second dirty blockage detection device detect dirty blockage is not limited. For example, the dirty blockage condition can be determined by detecting the change in the pressure value at both ends of the inlet and outlet of the filter through a pressure detection device, and the dirty blockage condition can also be determined by measuring the wind speed before and after the filter through an anemometer.

[0072] In an achievable manner, the first dirty blockage detection device is arranged in the main air duct 31, and is used to detect the first wind speed in the main air duct 31, and the second dirty blockage detection device is arranged in the auxiliary air duct 32, and is used to detect the second wind speed in the auxiliary air duct 32. The control device is configured to determine the dirty blockage of the first filter according to the first wind speed, and to determine the dirty blockage of the second filter according to the second wind speed. For example, in the process of detecting the dirty blockage of the filter, the control device controls the main fan 21 and the auxiliary fan 22 to start at the same time in the same rotation direction according to the preset speed, and determines that the first filter is dirty and blocked when the first wind speed is less than the first set wind speed, and determines that the second filter is dirty and blocked when the second wind speed is less than the second set wind speed. The magnitude of the first set wind speed is related to the rotation speed of the main fan 21, and the magnitude of the second set wind speed is related to the rotation speed of the auxiliary fan 22. Exemplarily, the air outlet directions of the main fan 21 and the auxiliary fan 22 are both toward the air inlet, so as to improve the accuracy of detecting the dirty blockage of the first filter and the second filter.

[0073] Preferably, before the control device controls the main fan 21 and the auxiliary fan 22 to start at the same time at the preset speed and in the same rotation direction, the control device first controls the main fan 21 and the auxiliary fan 22 to start at the same time at the preset speed and in the opposite rotation direction, at this time, a short-circuited circulation air path is formed between the main air duct 31 and the auxiliary air duct 32 (the airflow direction refers to Figure 4 The third wind speed in the main air duct 31 and / or the auxiliary air duct 32 is then determined. If the third wind speed is less than the third set wind speed, it indicates that at least one of the first filter and the second filter is dirty and blocked. At this time, the main fan 21 and the auxiliary fan 22 are controlled to start at the same time in the same rotation direction according to the preset speed to further determine whether the first filter is dirty or blocked. The magnitude of the third set wind speed is related to the speed of the main fan 21 and the auxiliary fan 22.

[0074] During the clothes drying process, this embodiment can intelligently control the main fan 21 and the auxiliary fan 22 to rotate in opposite directions, thereby achieving controllable internal circulation short-circuiting of the airflow inside the device, and real-time monitoring and evaluation of the status of the filter screen without affecting the normal drying of the clothes.

[0075] In an optional implementation, the clothing processing equipment also includes a first spray device and a second spray device. The first spray device is arranged in the clothing processing drum 1 and the spraying direction of the first spray device is toward the first filter. The first spray device is used to spray the first filter when the first filter is dirty or clogged. The second spray device is arranged in the clothing processing drum 1 and the spraying direction of the second spray device is toward the second filter. The second spray device is used to spray the second filter when the second filter is dirty or clogged.

[0076] In this embodiment, when the first filter is clogged with dirt, the control device first controls the first spray device to spray the first filter before controlling the heat pump system to be in the startup state, and then controls the heat pump system to be in the startup state, and controls the air outlet direction of the main fan 21 to be toward the first filter, and controls the refrigerant flow direction of the first refrigerant circulation flow path to be a refrigerant flow direction that enables the main fan 21 to blow hot air to the first filter. It is also possible to control the refrigerant flow direction of the first refrigerant circulation flow path to be a refrigerant flow direction that enables the main fan 21 to blow hot air to the first filter while the first spray device sprays the first filter.

[0077] Similarly, when the second filter is clogged with dirt, the control device first controls the second spray device to spray the second filter before controlling the heat pump system to be in the startup state, and then controls the heat pump system to be in the startup state, and controls the air outlet direction of the auxiliary fan 22 toward the second filter, and controls the refrigerant flow direction of the second refrigerant circulation flow path to be a refrigerant flow direction that enables the auxiliary fan 22 to blow hot air to the second filter. It is also possible to control the refrigerant flow direction of the second refrigerant circulation flow path to be a refrigerant flow direction that enables the auxiliary fan 22 to blow hot air to the second filter while the second spray device sprays the second filter.

[0078] This embodiment further improves the cleaning effect of the filter by combining spray cleaning with blowing hot air to the filter.

[0079] Embodiment 2

[0080] This embodiment proposes a filter cleaning method for a clothes processing device, which is applied to the clothes processing device with a drying function proposed in the first embodiment. The filter cleaning method can be operated in a separate filter cleaning mode or can be executed simultaneously during the drying process. Figure 5 As shown in the flowchart, the filter cleaning method includes the following steps:

[0081] S51, during the filter cleaning process, controlling the heat pump system to be in a startup state;

[0082] S52, controlling the rotation direction of the main fan 21 and the auxiliary fan 22 according to the dirtiness and blockage conditions of the first filter and the second filter, and controlling the refrigerant flow direction of the first refrigerant circulation flow path and the second refrigerant circulation flow path.

[0083] In an optional implementation, the rotation direction of the main fan 21 and the auxiliary fan 22 is controlled according to the dirtiness and blockage of the first filter and the second filter, and the refrigerant flow direction of the first refrigerant circulation flow path and the second refrigerant circulation flow path is controlled, including:

[0084] When the first filter is dirty or clogged, the air outlet direction of the main fan 21 is controlled to be toward the first filter, and the refrigerant flow direction of the first refrigerant circulation path is controlled to enable the main fan 21 to blow hot air toward the first filter; when the second filter is dirty or clogged, the air outlet direction of the auxiliary fan 22 is controlled to be toward the second filter, and the refrigerant flow direction of the second refrigerant circulation path is controlled to enable the auxiliary fan 22 to blow hot air toward the second filter.
