DETAILED DESCRIPTION

[0033] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the following will be combined with the drawings in the embodiments of the present application to make a clear and complete description of the technical solutions in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0034] The laundry treating apparatus according to the present application will be described below with reference to the accompanying drawings, which includes, but is not limited to, a washer-dryer and a dryer.

[0035] The heat pump type washer-dryer includes a heat pump system, a fan 31 and an air duct, the heat pump system includes an evaporator, a condenser, a compressor and an expansion valve (not shown), the evaporator, the condenser and the fan 31 are arranged in the air duct, wherein the inner drum 20 is used to place the laundry to be dried, the fan 31 is used to realize the gas circulation between the inner drum 20 and the heat pump system, that is, the low-temperature and high-humidity air in the inner drum 20 enters into the air duct under the action of the fan 31, the low-temperature and high-humidity air is heated and dehumidified to form high-temperature and low-humidity dry hot air by the action of the heat pump system, the dry hot air enters into the inner drum 20 to dry the laundry, thereby realizing one working cycle. The lint cleaning structure of the laundry treating apparatus and the laundry treating apparatus according to the present application will be introduced below in combination with the heat pump type washer-dryer.

[0036] As shown in Figure 1 , Figure 2 , Figure 5 and Figure 6 , the laundry treating apparatus according to the embodiments of the present application includes a housing 10, an inner drum 20 and an air duct 30.

[0037] Specifically, the inner cylinder 20 is arranged in the shell 10, and the inner cylinder 20 defines a washing cavity with one end being open; the air duct 30 is arranged in the shell 10, and two ends of the air duct 30 are respectively communicated with the inner cylinder 20, the air duct 30 defines an air passage, and opposite convex portions 32 and concave portions 34 are arranged on the inner wall of the air duct 30, the convex portions 32 protrude towards the concave portions 34, and the concave portions 34 are recessed away from the convex portions 32, the air passage is arranged with the fan 31 and the spraying assembly 40 at intervals, the spraying assembly 40 is arranged with the first water spraying hole group 41 and the second water spraying hole group 42, the first water spraying hole group 41 is opposite to the concave portions 34, and the second water spraying hole group 42 is opposite to the convex portions 32.

[0038] In detail, the air passage is used for drying, the air passage is arranged with the first air inlet, the second air inlet 37, the first air outlet and the second air outlet 38, the first air inlet is communicated with the outside of the shell 10, the first air outlet is communicated with the outside of the shell 10, and two ends of the air passage are respectively communicated with the inner cylinder 20 through the second air inlet and the second air outlet 38; when the wind mixed with the lint, the thread scraps and the like passes through the concentrated portions of the air passage, the direction of the wind is changed suddenly, and the wind directly hits the convex portions 32 and the concave portions 34. Because the lint, the thread scraps and the like cannot follow the wind to enter the air passage in a wet state, when the lint, the thread scraps and the like can follow the wind to enter the air passage, the condensed water has begun to enter the air passage, the inner wall of the air duct 30 is covered with the condensed water, and at this time, the wind with the lint, the thread scraps and the like hits the convex portions 32 and the concave portions 34. The condensed water attached to the convex portions 32 and the concave portions 34 helps the lint, the thread scraps and the like to be attached and stay, so that the wind after passing through the convex portions 32 and the concave portions 34 almost does not contain the lint, the thread scraps and the like. The spraying assembly 40 can be opened regularly, the first water spraying hole group 41 is opposite to the concave portions 34, and the second water spraying hole group 42 is opposite to the convex portions 32, so that the concave portions 34 and the convex portions 32 can be washed by water, the lint, the thread scraps and the like are washed away, so that the convex portions 32 and the concave portions 34 are cleaned regularly without manual periodical cleaning, the drying effect of the clothes treatment equipment is guaranteed, and the running state of the whole machine is also guaranteed to be good.

[0039] According to the clothes treatment equipment provided by the embodiment of the present application, the convex portions 32 and the concave portions 34 are arranged in the air passage, when the wind mixed with the lint, the thread scraps and the like passes through the concentrated portions of the air passage, the direction of the wind is changed suddenly, and the wind directly hits the convex portions 32 and the concave portions 34. The convex portions 32 and the concave portions 34 give the lint, the thread scraps and the like resistance to continue to move, and the lint, the thread scraps and the like are attached to the convex portions 32 and the concave portions 34. The spraying assembly 40 can be opened to clean the convex portions 32 and the concave portions 34, so that the lint, the thread scraps and the like accumulated on the convex portions 32 and the concave portions 34 can be cleaned automatically, manual periodical cleaning is not needed, and the drying effect of the clothes treatment equipment is guaranteed.

[0040] The distance between the side wall of the air duct 30 where the convex part 32 is located and the side wall of the air duct 30 where the concave part 34 is located is consistent in the extension direction, so that the air volume and the air speed in the air duct and other parameters are not affected, and the drying effect of the clothes treatment equipment is prevented from being affected.

[0041] As shown in Figure 1 and Figure 2 , according to the clothes treatment equipment of the embodiment of the present application, along the airflow direction, the convex part 32 includes the first side wall 322 and the second side wall 324 connected in sequence, and the concave part 34 includes the third side wall 342 and the fourth side wall 344 connected in sequence, the first side wall 322 and the third side wall 342 are oppositely and parallelly arranged, and the second side wall 324 and the fourth side wall 344 are oppositely and parallelly arranged, so that the structure of the convex part 32 and the concave part 34 can be simplified, and when the lint, thread scraps and other sundries pass through the first side wall 322 and the third side wall 342, they are easily deposited due to resistance, the area of the convex part 32 and the concave part 34 for depositing dust is increased, and at the same time, the air speed and other parameters are not affected as much as possible, and the drying effect of the clothes treatment equipment is prevented from being affected.

[0042] The distance between the first side wall 322 and the third side wall 342 is equal to the distance between the second side wall 324 and the fourth side wall 344.

[0043] It should be noted that the airflow flow direction refers to the airflow flow direction of the airflow in the inner drum 20 entering the air duct through the second air inlet 37. The air duct 30 further includes an air inlet 30 of the shell 10 interface, a bellows and a two-device installation chamber (a chamber for installing a condenser and an evaporator in a heat pump system). The shell 10 interface is connected with the shell 10, that is, the shell 10 interface is a connecting pipe extending from the shell 10, that is, the second air outlet 38 described above. The bellows is in communication with the air inlet 30 of the shell 10 interface and the two-device installation chamber, that is, the second air inlet 37 described above.

[0044] As shown in Figure 2 and Figure 3 , in some embodiments, the included angle between the first side wall 322 and the bottom surface of the convex part 32 is α, and the range of α satisfies: 30°≦α<90°. The greater the included angle α, the greater the resistance to the air, and the more likely to block the lint, thread scraps and other sundries, and the greater the influence on the air speed. The smaller the included angle α, the smaller the resistance to the air, and the less likely to block the lint, thread scraps and other sundries, so it is necessary to set a reasonable size of the included angle α. The included angle α can be 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65°, 70°, 75°, 80° and 85°, etc.

[0045] As shown in Figure 2 and Figure 3As shown, in some embodiments, the included angle between the second side wall 324 and the bottom surface of the convex portion 32 is β, and the range of β satisfies: 30°≦β<90°. The greater the included angle β, the smaller the included angle α, the smaller the resistance of the first side wall 322 to the wind, and the less likely to block the hair and lint and other sundries. The smaller the included angle β, the greater the included angle α, the greater the resistance to the wind, the more likely to block the hair and lint and other sundries, and the greater the influence on the wind speed. Therefore, it is necessary to set a reasonable size of the included angle β.

[0046] Among them, the included angle β can be 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65°, 70°, 75°, 80°, and 85°, etc.

[0047] As shown in Figure 3 and Figure 4 As shown, in some embodiments, at least one of the first side wall 322 and the third side wall 342 is provided with a plurality of convex points 346. Among them, the first side wall 322 and the third side wall 342 are more resistant to wind than the second side wall 324 and the fourth side wall 344. The convex points 346 covered by the condensed water help the hair and lint and other sundries to adhere to the first side wall 322 and the third side wall 342, thereby further enhancing the cleaning effect of the air duct on sundries.

[0048] It should be noted that, for the convenience of explanation, the convex points 346 provided on the first side wall 322 are named as first convex points, and the convex points 346 provided on the third side wall 342 are named as second convex points. The plurality of first convex points can be uniformly distributed on the first side wall 322 or can be distributed in a certain specific pattern. The plurality of second convex points can be uniformly distributed on the third side wall 342 or can be distributed in a certain specific pattern.

[0049] As shown in Figure 2 As shown, in some embodiments, the spraying assembly 40 includes a spraying head 43 and a water spraying valve. The spraying head 43 is inclinedly arranged, and the first water spraying hole group 41 and the second water spraying hole group 42 are arranged on the spraying head 43. The height of the first water spraying hole group 41 is higher than the height of the second water spraying hole group 42. In this way, the spraying range of the first water spraying hole group 41 can cover the entire third side wall 342, and the spraying range of the second water spraying hole group 42 can cover the entire first side wall 322, so as to ensure that each area of the first side wall 322 and the third side wall 342 can be washed clean.

[0050] In some embodiments, the first water spraying hole group 41 includes a plurality of first water spraying holes, and the second water spraying hole group 42 includes a plurality of second water spraying holes. The height of at least part of the first water spraying holes is higher than the height of all the second water spraying holes. That is, the height of all the first water spraying holes can be higher than the height of all the second water spraying holes, or the height of part of the first water spraying holes can be higher than the height of all the second water spraying holes.

[0051] like Figure 1 As shown, in some embodiments, the garment processing device further includes a drainage channel 50, which includes a drain outlet 52 located at the bottom of the housing 10. The air duct and the drainage channel 50 are connected through a guide port 36 located above the drain outlet 52. This allows lint, lint, and other debris washed down from the protrusions 32 and recesses 34 to be discharged into the drainage channel 50 from the washing water of the garment processing device through the guide port 36 and then discharged through the drain outlet 52, without the need for additional drainage pipes.

[0052] According to the clothing processing device of the present invention, the protrusion 32 and the concave portion 34 are located upstream of the fan 31 along the direction of airflow, which reduces the amount of lint and dander blown toward the fan 31 and ensures the normal operation of the fan 31.

[0053] like Figure 1 As shown, the protrusion 32 and the recess 34 are located between the end of the inner cylinder 20 away from the opening and the inner wall of the rear side of the housing 10.

[0054] According to an embodiment of the clothing processing device of the present invention, a main control unit is further provided inside the housing 10, and a detection sensor is provided inside the air duct. The detection sensor is disposed opposite to the protrusion 32 or the recess 34. The detection sensor is used to detect the degree of debris accumulation on the protrusion 32 and / or the recess 34. The detection sensor is electrically connected to the main control unit.

[0055] The detection sensors include, but are not limited to, infrared sensors and pressure sensors. When the detection sensor is an infrared sensor, it can be installed on both the first sidewall 322 and the third sidewall 342, or on one of the first sidewall 322 and the third sidewall 342. In the direction of airflow, the difference in the degree of debris accumulation on the first sidewall 322 and the third sidewall 342 is not significant, so both can be detected, or only one can be detected and cleaned, with little impact. When the detection sensor is a pressure sensor, it can be installed on both the first sidewall 322 and the third sidewall 342, or on one of the first sidewall 322 and the third sidewall 342. In the direction of airflow, the difference in the degree of debris accumulation on the first sidewall 322 and the third sidewall 342 is not significant, so both can be detected, or only one can be detected and cleaned, with little impact.

[0056] In some embodiments, the housing 10 also includes a communication unit, which is electrically connected to the main control unit and can interact with a mobile terminal. The mobile terminal has a menu that corresponds to the control panel of the garment processing equipment, allowing the user to operate and control the garment processing equipment via the mobile terminal.

[0058] Step S1: detecting the degree of accumulation of sundries on the convex part 32 and / or the concave part 34;

[0059] Step S2: determining whether to start the spraying assembly 40 according to the degree of accumulation of sundries.

[0060] According to the control method of the embodiment of the application, when it is detected that the dust on the convex part 32 and / or the concave part 34 needs to be cleaned, the spraying assembly 40 is started to clean the dust, so as to guarantee the drying effect of the clothes processing device and prevent the operation effect of the whole machine from being poor.

[0061] According to the control method of the embodiment of the application, whether to start the spraying assembly 40 is determined according to the degree of accumulation of sundries, and specifically comprises the following steps:
