[0002] In clothing processing equipment with drying functions, such as dryers and washer-dryers, the filter is a key component used to capture and remove dust, lint, and particulate matter during the drying process. Its cleanliness and unobstructed flow directly affect the normal operation and drying efficiency of the equipment. Over time, dust and lint gradually accumulate on the filter, causing it to become clogged, which in turn affects the normal operation and drying efficiency of the equipment. Traditional filter cleaning methods often rely on regular manual cleaning, which is not only cumbersome but also makes it difficult to address filter clogging issues promptly and effectively.

[0054] 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.

[0055] Example 1

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

[0057] A cavity is formed within the housing, and a clothes processing drum 1 is housed within the cavity. The clothes processing drum 1 has an air inlet, a first air outlet, and a second air outlet. The positions of the air inlet, the first air outlet, and the second air outlet are not specifically defined. In one example, a door seal is provided at the opening of the clothes processing drum 1, the air inlet is located at the door seal, and the first and second air outlets are located at the bottom of the clothes processing drum 1. This creates a relatively long airflow path between the air inlet and the first and second air outlets, allowing the airflow to penetrate the clothes and ensuring a uniform drying effect.

[0058] The air duct assembly is disposed in the space between the housing and the garment processing cylinder 1, preferably above the garment processing cylinder 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, and the auxiliary air duct 32 connects the second air inlet and the second air outlet. The main fan 21 is disposed in the main air duct 31, and the auxiliary fan 22 is disposed in the auxiliary air duct 32. A circulating air path is formed between the garment processing cylinder 1 and the main air duct 31, and between the garment processing cylinder 1 and the auxiliary air duct 32. The rotation directions of the main fan 21 and the auxiliary fan 22 can be changed as needed.

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

[0060] The heat pump system includes a first refrigerant circulation path and a second refrigerant circulation path with variable refrigerant flow direction. The first refrigerant circulation path heats and dehumidifies the airflow in the main air duct 31, and the second refrigerant circulation path heats and dehumidifies the airflow in the auxiliary air duct 32. The flow direction of both the first and second refrigerant circulation paths can be changed as needed. Both the first and second refrigerant circulation paths include a compressor 9, a reversing device, a condenser, a throttling device, and an evaporator, which are sequentially connected via refrigerant piping. The first and second refrigerant circulation paths can have their own independent compressor 9, reversing device, condenser, throttling device, and evaporator, or they can share the compressor 9 and the 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 located in the main air duct 31, with the first heat exchanger 51 positioned close to the air inlet. The third heat exchanger 52 and the fourth heat exchanger 42 are located in the auxiliary air duct 32, with the third heat exchanger 52 positioned close to the air inlet. The compressor 9, the reversing device, the first heat exchanger 51, and the second heat exchanger 41 are connected by refrigerant pipelines to form a first refrigerant circulation path. The compressor 9, the reversing device, the third heat exchanger 52, and the fourth heat exchanger 42 are connected by refrigerant pipelines to form a second refrigerant circulation path. During the drying process, the refrigerant in the first refrigerant circulation path flows from the second heat exchanger 41 to the first heat exchanger 51, that is, the second heat exchanger 41 acts as an evaporator and the first heat exchanger 51 acts as a condenser; the refrigerant in the second refrigerant circulation path flows from the fourth heat exchanger 42 to the third heat exchanger 52, that is, the fourth heat exchanger 42 acts as an evaporator and the third heat exchanger 52 acts as a condenser.

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

[0063] A first filter covers the first air outlet and is used to filter the airflow entering the main air duct 31. A 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 running state during the filter cleaning process, and to control the rotation direction of the main fan 21 and the auxiliary fan 22, as well as the refrigerant flow direction of the first and second refrigerant circulation paths, based on the degree of dirt accumulation on the first and second filters.

[0064] Specifically, such as Figure 2 As shown, when the first filter becomes clogged, the control device activates the heat pump system and directs the main fan 21 to direct the airflow towards the first filter (airflow direction reference). Figure 2(As indicated by the middle arrow), the refrigerant flow direction of the first refrigerant circulation path is controlled to be the refrigerant flow direction that enables the main fan 21 to blow hot air to the first filter screen. That is, by controlling the reversing device, 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 acts as an evaporator and the second heat exchanger 41 acts as a condenser.

[0065] When the second filter becomes clogged, the control device controls the heat pump system to start, controls the auxiliary fan 22 to blow air towards the second filter, and controls the refrigerant flow direction in the second refrigerant circulation path to be such that the auxiliary fan 22 blows hot air towards the second filter. That is, by controlling the reversing device, 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 both the first and second filters become clogged, the control device activates the heat pump system, directing the main fan 21 to blow air towards the first filter and the auxiliary fan 22 to blow air towards the second filter (airflow direction reference). Figure 3 (As indicated by the middle arrow), the refrigerant flow direction of the first refrigerant circulation path is controlled to be the refrigerant flow direction that enables the main fan 21 to blow hot air to the first filter screen, and the refrigerant flow direction of the second refrigerant circulation path is controlled to be the refrigerant flow direction that enables the auxiliary fan 22 to blow hot air to the second filter screen.

[0067] The clothing processing equipment in this embodiment uses a heat pump system with a first refrigerant circulation path and a second refrigerant circulation path. While heating and dehumidifying the airflow distribution in the main air duct 31 and the auxiliary air duct 32, it can also coordinately control the flow direction of the first and second refrigerant circulation paths, as well as the rotation direction of the main fan 21 and the auxiliary fan 22, when the first filter and / or the second filter becomes clogged. This allows hot air to be blown onto the clogged filter, accelerating the removal of lint from the filter surface. Furthermore, if the clogged filter has been pre-cleaned by spraying, blowing hot air onto it can also accelerate the evaporation rate of the water film, significantly improving the cleaning effect of the filter.

[0068] Further preferred, such as Figure 4 As shown, when one of the first and second filters becomes clogged, the control device also controls the airflow direction of the fan corresponding to the clogged filter to be towards the clogged filter, and controls the airflow direction of the fan corresponding to the unclogged filter to be towards the air inlet. At this time, a short-circuit circulation air path is formed between the main air duct 31 and the auxiliary air duct 32 (airflow direction refers to...). Figure 4(As indicated by the middle arrow), thereby improving the airflow circulation efficiency between the main air duct 31 and the auxiliary air duct 32, enhancing the removal efficiency of lint from clogged filters, and accelerating the breaking down of water films on the filters, further improving the cleaning effect. Furthermore, this embodiment can also efficiently clean the filters during the drying process without affecting the normal drying procedure.

[0069] The method for determining the clogging status of the first and second filters in this embodiment is not limited.

[0070] In one example, after receiving a user's filter cleaning instruction, the system determines the degree of filter clogging based on the cumulative number of dryers since the most recent filter cleaning. For example, if the cumulative number of dryers since the most recent filter cleaning is less than a set number, the filter is determined to be lightly clogged and does not require cleaning; if the cumulative number of dryers since the most recent filter cleaning is greater than the set number, the filter is determined to be heavily clogged and requires cleaning.

[0071] In another example, the garment processing equipment also includes a first dirt clogging detection device and a second dirt clogging detection device. The first dirt clogging detection device is used to detect the dirt clogging status of the first filter screen, and the second dirt clogging detection device is used to detect the dirt clogging status of the second filter screen. This embodiment, by setting the first and second dirt clogging detection devices, can accurately detect the dirt clogging status of the first and second filters, thereby achieving targeted cleaning of the first and second filters. The method by which the first and second dirt clogging detection devices detect dirt clogging is not limited. For example, a pressure detection device can be used to detect changes in pressure values ​​at both ends of the filter screen to determine the dirt clogging status, or an anemometer can be used to measure the wind speed before and after the filter screen to determine the dirt clogging status.

[0072] In one feasible implementation, a first clogging detection device is located within the main air duct 31 to detect a first air velocity within the main air duct 31, and a second clogging detection device is located within the auxiliary air duct 32 to detect a second air velocity within the auxiliary air duct 32. The control device is configured to determine the clogging status of the first filter based on the first air velocity, and to determine the clogging status of the second filter based on the second air velocity. For example, during filter clogging detection, the control device controls the main fan 21 and the auxiliary fan 22 to start simultaneously at preset speeds in the same direction of rotation. If the first air velocity is less than the first preset air velocity, the first filter is determined to be clogged; if the second air velocity is less than the second preset air velocity, the second filter is determined to be clogged. The magnitude of the first preset air velocity is related to the rotational speed of the main fan 21, and the magnitude of the second preset air velocity is related to the rotational speed of the auxiliary fan 22. For example, the air outlet directions of both the main fan 21 and the auxiliary fan 22 are directed towards the air inlet to improve the accuracy of detecting the clogging status of the first and second filters.

[0073] Preferably, before the control device starts the main fan 21 and the auxiliary fan 22 simultaneously at preset speeds and in the same direction of rotation, the control device first starts the main fan 21 and the auxiliary fan 22 simultaneously at preset speeds and in opposite directions of rotation. At this time, a short-circuit circulation air path is formed between the main air duct 31 and the auxiliary air duct 32 (airflow direction refers to...). Figure 4 (As indicated by the middle arrow) Then, determine the third air velocity within the main air duct 31 and / or auxiliary air duct 32. If the third air velocity is less than the third set air velocity, it indicates that at least one of the first and second filters is clogged. In this case, control the main fan 21 and auxiliary fan 22 to start simultaneously at preset speeds in the same direction of rotation to further determine whether the clog is in the first or second filter. The magnitude of the third set air velocity is related to the rotational speeds of the main fan 21 and auxiliary fan 22.

[0074] In this embodiment, during the clothes drying process, the main fan 21 and the auxiliary fan 22 can be intelligently controlled to rotate in opposite directions, thereby achieving a controllable internal circulation of airflow within the equipment. This allows for real-time monitoring and evaluation of the filter's condition without affecting the normal drying of the clothes.

[0075] In one alternative implementation, the garment processing equipment further includes a first spray device and a second spray device. The first spray device is disposed inside the garment processing cylinder 1 and its spray direction is towards the first filter screen. The first spray device is used to spray the first filter screen when it is clogged. The second spray device is disposed inside the garment processing cylinder 1 and its spray direction is towards the second filter screen. The second spray device is used to spray the second filter screen when it is clogged.

[0076] In this embodiment, when the first filter becomes clogged, the control device first controls the first spray device to spray the first filter before starting the heat pump system, then starts the heat pump system, and directs the main fan 21's airflow towards the first filter. The refrigerant flow direction in the first refrigerant circulation path is also controlled to ensure that the main fan 21 blows hot air towards the first filter. Alternatively, the refrigerant flow direction in the first refrigerant circulation path can be controlled to ensure that the main fan 21 blows hot air towards the first filter while the first spray device is spraying the first filter.

[0077] Similarly, when the second filter becomes clogged, the control device first controls the second spray device to spray the second filter before starting the heat pump system, then starts the heat pump system, directs the auxiliary fan 22 towards the second filter, and controls the refrigerant flow direction in the second refrigerant circulation path to allow the auxiliary fan 22 to blow hot air onto the second filter. Alternatively, the control device can simultaneously spray the second filter with the second spray device and control the refrigerant flow direction in the second refrigerant circulation path to allow the auxiliary fan 22 to blow hot air onto the second filter.

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

[0079] Example 2

[0080] This embodiment proposes a method for cleaning the filter of a garment processing device. The filter cleaning method is applied to the garment processing device with a drying function proposed in Embodiment 1. The filter cleaning method can operate in a standalone filter cleaning mode or be performed simultaneously during the drying process. Figure 5 The flowchart shown illustrates the filter cleaning method, which includes the following steps:

[0081] S51. During the filter cleaning process, keep the heat pump system in the start state;

[0082] S52. Control the rotation direction of the main fan 21 and the auxiliary fan 22 according to the dirt and clogging status of the first filter and the second filter, and control the refrigerant flow direction of the first refrigerant circulation path and the second refrigerant circulation path.

[0083] In one optional implementation, controlling the rotation direction of the main fan 21 and the auxiliary fan 22, and controlling the refrigerant flow direction in the first and second refrigerant circulation paths, based on the clogging status of the first and second filters, includes:

[0084] When the first filter is clogged, the main fan 21 is directed to blow air towards the first filter, and the refrigerant flow direction in the first refrigerant circulation path is controlled to allow the main fan 21 to blow hot air towards the first filter. When the second filter is clogged, the auxiliary fan 22 is directed to blow air towards the second filter, and the refrigerant flow direction in the second refrigerant circulation path is controlled to allow the auxiliary fan 22 to blow hot air towards the second filter.

[0085] Preferably, if one of the first and second filters becomes clogged, the airflow direction of the fan corresponding to the clogged filter is controlled to be towards the clogged filter, and the airflow direction of the fan corresponding to the unclogged filter is controlled to be towards the air inlet. At this time, an internal circulation short-circuit air duct is formed between the main air duct 31 and the auxiliary air duct 32, improving the cleaning efficiency of the filters without affecting the operation of the drying process.

[0086] In one alternative implementation, such as Figure 6 The flowchart shown illustrates the steps used to determine the clogging status of the first and second filters:

[0087] S61. Control the main fan 21 and the auxiliary fan 22 to start simultaneously in the same direction of rotation according to the preset speed;

[0088] S62. Determine the first wind speed in the main air duct 31 and the second wind speed in the auxiliary air duct 32.

[0089] S63. If the first wind speed is less than the first set wind speed, determine that the first filter is clogged; if the second wind speed is less than the second set wind speed, determine that the second filter is clogged.

[0090] In one alternative implementation, such as Figure 7 The flowchart shown illustrates that the filter cleaning method also includes the following steps:

[0091] S71. Control the main fan 21 and the auxiliary fan 22 to start simultaneously in opposite directions of rotation according to the preset speed;

[0092] S72. Determine the third wind speed within the main air duct 31 and / or the auxiliary air duct 32;

[0093] S73. When the third wind speed is less than the third set wind speed, execute the step of controlling the main fan 21 and the auxiliary fan 22 to start simultaneously in the same direction of rotation according to the preset speed.

[0094] In one alternative implementation, when the garment processing equipment has a first spraying device capable of spraying a first filter and a second spraying device capable of spraying a second filter, the filter cleaning method includes the following steps before or during the start-up of the heat pump system:

[0095] When the first filter screen becomes clogged, the first spray device is controlled to spray water onto the first filter screen.

[0096] When the second filter screen becomes clogged, the second spray device is controlled to spray the second filter screen.
