[0052] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0053] See also Figure 1 As shown, the present application provides a lint cleaning control method, which is applied to a drum-type washing device, wherein the drum-type washing device comprises an outer drum and a drum rotatably disposed in the outer drum, wherein a plurality of lifting ribs that rotate with the drum are evenly arranged at intervals in the circumferential direction on the inner wall surface of the drum, wherein a lifting rib cavity is formed inside the lifting rib, and the lifting rib is provided with a lint removal structure and a through hole that allows water and lint in the drum cavity to flow into the lifting rib cavity on the side wall surface facing the drum cavity;

[0054] In the process of controlling the drum to alternately rotate forward and reverse at a preset hair removal and washing water level to clean the hair debris, the hair scraps cleaning control method first rotates the drum so that one of the lifting ribs is located at the bottom of the drum, and uses the rotation position of the drum at this time as a reference position to control the drum to alternately rotate forward and reverse at a preset rotation angle α;

[0055] Among them, the preset angle α is the rotation angle of the drum relative to the reference position, α=β*n, wherein β is the central angle between two adjacent lifting ribs, β=360° / m, m is the number of lifting ribs, and n is a positive integer greater than or equal to 1.

[0056] For example, when three lifting ribs are evenly spaced around the inner wall of the drum, that is, m=3, the central angle β between two adjacent lifting ribs is 120°, and the preset angle α can be an integer multiple of 120° such as 120°, 240°, 360°, 480°, etc.

[0057] The purpose of the dander cleaning control method of the present application is to increase the number of times the lifting ribs hit and rub the clothes, so as to facilitate the removal of the hair adhering to the clothes. Therefore, in the process of cleaning the dander, the position of the lifting ribs is first adjusted. The method of adjusting the position of the lifting ribs is to rotate the drum so that one of the lifting ribs is located at the bottom of the drum. After the position of the lifting ribs is adjusted, the rotation position of the drum at this time is used as the reference position, and the drum is controlled to rotate alternately forward and reverse at a preset rotation angle α;

[0058] When the drum rotates alternately forward and reverse at a preset rotation angle α, the lifting ribs at the bottom of the drum bring the clothes to a high place and then drop them down. Due to the design of the rotation angle α, there is always a lifting rib at the bottom every time the drum stops. When the clothes fall, they will contact the lifting ribs at the bottom. Then the drum reverses at an angle α, and the clothes are brought to a high place again and then fall down. The clothes contact the lifting ribs at the bottom of the drum again. This reciprocating process continues for a preset time. The clothes are continuously beaten and constantly contact the lifting ribs, so that the hair stuck on the clothes is peeled off.

[0059] In one embodiment, the dander cleaning control method provided by the present application further includes:

[0060] Obtaining a target cleaning stage for performing dander cleaning;

[0061] Determine and execute a hair removal cleaning strategy according to the target cleaning stage;

[0062] in,

[0063] Different cleaning strategies are used at different target cleaning stages;

[0064] Different cleaning strategies correspond to different hair removal times and / or hair removal water levels and / or preset hair removal times and / or preset rotation angles.

[0065] Specifically, the hair removal cleaning strategy is determined according to the target cleaning stage and executed including the following control steps:

[0066] Filling water into the drum to a preset hair removal and washing water level according to the target cleaning stage;

[0067] The drum is controlled to alternately rotate forward and reverse at the preset angle α for a preset time period.

[0068] like Figure 1As shown, specifically, the target cleaning stage includes a main washing stage. In the main washing stage, water is injected into the drum to a preset hair removal washing water level according to the target cleaning stage, and the drum is controlled to alternately rotate forward and reverse at the preset angle α for a preset time period, including:

[0069] S1: Fill the outer drum with water to a first preset hair removal and washing water level H1 at one time.

[0070] The first hair removal washing water level H1 is a low water level, which is a water level with some surplus on the basis of ensuring that the clothes are wet. After the clothes have fully absorbed water in the first hair removal washing water level H1, the first hair removal washing water level H1 is lower than the highest point of the clothes. The specific water level can be set according to the weight of the clothes.

[0071] S2: Control the drum to rotate alternately forward and reverse at a first preset rotation angle α1, and start timing; wherein, α1=β*n1, wherein β is the central angle between two adjacent lifting ribs, β=360° / m, m is the number of the lifting ribs, and n1 is a positive integer greater than or equal to 1.

[0072] When three lifting ribs are evenly arranged on the inner wall of the drum in the circumferential direction, that is, m=3, the central angle β between two adjacent lifting ribs is 120°, and the preset angle α1 can be an integer multiple of 120°, such as 120°, 240°, 360°, 480°, etc.;

[0073] When the drum rotates alternately forward and reverse at a preset rotation angle α1, the lifting ribs at the bottom of the drum bring the clothes to a high place and then drop them down. Due to the design of the rotation angle α1, there is always a lifting rib at the bottom every time the drum stops. When the clothes fall, they will contact the lifting ribs at the bottom. Then the drum reverses by an angle α1, and the clothes are brought to a high place again and then fall down. The clothes contact the lifting ribs at the bottom of the drum again. This reciprocating process continues for a preset time. The clothes are continuously beaten and constantly contact the lifting ribs, so that the hair stuck on the clothes is peeled off.

[0074] S3: When the first preset time T1 is reached, the water in the drum is drained outwards.

[0075] When the first preset time T1 is reached, the main wash is completed and the sewage and hair in the washing device are discharged.

[0076] like Figure 1 As shown, specifically, the target cleaning stage also includes a rinsing stage, and in the rinsing stage, the hair removal cleaning strategy includes:

[0077] S4: Fill water into the outer drum to the second hair removal and washing water level H2.

[0078] The second hair removal washing water level H2 is a low water level. The second hair removal washing water level H2 is a water level that has some surplus water on the basis of ensuring that the clothes are wet. After the clothes have fully absorbed water in the second hair removal washing water level H2, the second hair removal washing water level H2 is lower than the highest point of the clothes. The specific water level can be set according to the weight of the clothes. The second hair removal washing water level H2 can be the same as the first hair removal washing water level H1.

[0079] S5: Control the drum to rotate alternately forward and reverse at a second preset rotation angle α2, and start timing; wherein, α2=β*n2, wherein β is the central angle between two adjacent lifting ribs, β=360° / m, m is the number of the lifting ribs, and n2 is a positive integer greater than or equal to 1.

[0080] When three lifting ribs are evenly arranged on the inner wall of the drum in the circumferential direction, that is, m=3, the central angle β between two adjacent lifting ribs is 120°, and the preset angle α2 can be an integer multiple of 120°, such as 120°, 240°, 360°, 480°, etc.;

[0081] When the drum rotates alternately forward and reverse at a preset rotation angle α2, the lifting ribs at the bottom of the drum bring the clothes to a high place and then drop them down. Due to the design of the rotation angle α2, there is always a lifting rib at the bottom every time the drum stops. When the clothes fall, they will contact the lifting ribs at the bottom. Then the drum reverses at an angle α2, and the clothes are brought to a high place again and then fall down. The clothes contact the lifting ribs at the bottom of the drum again. This reciprocating process continues for a preset time. The clothes are continuously beaten and constantly contact the lifting ribs, so that the hair stuck on the clothes is peeled off.

[0082] S6: When the second preset time T2 is reached, water is injected into the outer drum to the third hair removal and washing water level H3.

[0083] The third hair removal and washing water level H3 is higher than the second hair removal and washing water level H2;

[0084] The third hair removal and washing water level H3 is a high water level. After the clothes fully absorb water in the third hair removal and washing water level H3, the third hair removal and washing water level H3 will submerge all the clothes.

[0085] S7: Control the drum to rotate alternately in forward and reverse directions at a third preset rotation angle α3, and start timing.

[0086] At this time, the normal washing mode is carried out, and the rotation ratio is directly set for washing without considering the rotation angle of the drum, so α3 can be any angle.

[0087] S8: When the third preset time T3 is reached, start drainage.

[0088] When the third preset time T3 is reached, rinsing is completed and the water and hair debris in the outer drum are discharged.

[0089] The hair cleaning control method provided by the present application increases the number of times that the lifting ribs hit and rub the clothes so as to facilitate the removal of hair attached to the clothes. During the process of the drum rotating alternately in forward and reverse directions at a preset rotation angle α, the lifting ribs located at the bottom of the drum bring the clothes to a high place and then drop them down. Due to the design of the rotation angle α, each time the drum stops, there is always a lifting rib at the bottom. When the clothes fall, they will contact the lifting ribs at the bottom. Then the drum reverses by an angle α, and the clothes are brought to a high place again and then fall down. The clothes contact the lifting ribs at the bottom of the drum again. This reciprocating process continues for a preset time. The clothes are continuously hit and constantly contact the lifting ribs, so that the hair attached to the clothes is removed.

[0092] See also Figure 5 As shown, the drum 2 is provided with three lifting ribs 1, and each time the washing device stops, there is a lifting rib 1 at the bottom. When rotating, the lifting rib brings the clothes to a high place and then drops them, and then reverses 120°·n, where n is a positive integer greater than or equal to 1, and the clothes are brought to a high place again and then fall. Each time the washing device stops, there is a lifting rib at the bottom, and the clothes will contact the lifting ribs at the bottom when they fall. This reciprocating process continues for a period of time, and the clothes are continuously beaten and continuously contact the lifting ribs, so that the hair attached to the clothes is peeled off.
