A dander cleaning control method and washing equipment

Abstract

This application belongs to the field of garment processing technology and discloses a lint cleaning control method and washing equipment. The lint cleaning control method, in the process of controlling the drum to alternately rotate forward and reverse at a preset lint removal water level for lint cleaning, first rotates the drum so that one of the lifting ribs is located at the bottom of the drum. Using the rotation position of the drum at this time as the reference position, the drum is controlled to alternately rotate forward and reverse at a preset rotation angle α, so that the lifting rib lifts the clothes to a high place and then drops them. Then, the angle reverses by α, so that the clothes are lifted to a high place again and then drop them. This ensures that there is always a lifting rib at the bottom each time the clothes stop. When the clothes fall, they will contact the bottom lifting rib. This process is repeated for a period of time, so that the clothes are continuously tumbled and in constant contact with the lifting ribs, thus peeling off the lint adhering to the clothes.

Description

Technical Field

[0001] This application relates to the field of washing equipment technology, specifically to a dander cleaning control method and washing equipment. Background Technology

[0002] With the increasing number of pet-owning families, while pets bring companionship and joy, they also bring some troubles, such as shed hair that is difficult to remove from clothing. Because most pet hair is fine and soft, it adheres tightly to clothing, and even after washing such clothes, a lot of hair will still be attached to the clothes after the wash.

[0003] Existing washing equipment structures and washing control methods are difficult to effectively remove pet hair, and the hair floating on the water surface can easily fall back onto clothing, causing secondary pollution. Therefore, this application is hereby submitted. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this application provides a lint removal control method and washing equipment. The lint removal control method first rotates the drum so that one of the lifting ribs is located at the bottom of the drum. Then, using the drum's current rotation position as a reference, the drum is controlled to alternately rotate forward and backward at a preset rotation angle α. This causes the lifting rib to lift the clothes to a high position and then drop them, followed by a reversal at the angle α, lifting the clothes to a high position again before dropping them. This ensures that at each stop, one lifting rib is always at the bottom, and the clothes contact this bottom lifting rib as they fall. This process is repeated for a period of time, continuously tumbling and contacting the clothes with the lifting ribs, thus removing the lint adhering to the clothes. This application solves the problem that existing washing equipment structures and washing control methods are ineffective at removing pet hair, and that lint floating on the water surface easily falls back onto the clothes, causing secondary pollution.

[0005] In a first aspect, this application provides a lint cleaning control method applied to a drum-type washing device. The drum-type washing device includes an outer drum and a drum rotatably disposed inside the outer drum. The inner sidewall of the drum is provided with a plurality of lifting ribs that rotate with the drum in a circumferentially uniform manner. The lifting ribs are provided with lifting rib cavities inside. The lifting ribs are provided with lint removal structures and through holes on the sidewall facing the drum cavity, allowing water and lint in the drum cavity to flow into the lifting rib cavity.

[0006] The dandruff cleaning control method, in the process of controlling the roller to alternately rotate forward and reverse at a preset dandruff removal water level for dandruff cleaning, first rotates the roller so that one of the lifting ribs is located at the bottom of the roller, and uses the rotation position of the roller at this time as a reference position to control the roller to alternately rotate forward and reverse at a preset rotation angle α.

[0007] Wherein, the preset angle α is the rotation angle of the roller relative to the reference position, α=β*n, where 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.

[0008] Alternatively, the control method may further include:

[0009] Obtain the target cleaning stage for dander removal;

[0010] Determine and execute the hair removal strategy based on the target cleaning stage;

[0011] in,

[0012] Different cleanup strategies are used for different target cleanup phases;

[0013] Different cleaning strategies correspond to different hair removal cycles and / or hair removal water levels and / or preset hair removal duration and / or preset rotation angle.

[0014] The above scheme may further optionally include the following control steps for determining and executing the hair removal strategy based on the target cleaning stage:

[0015] According to the target cleaning stage, water is injected into the drum to the preset lint removal washing water level;

[0016] The roller is controlled to rotate alternately in both forward and reverse directions at the preset angle α for a preset duration.

[0017] The above scheme can be further optionally defined as follows: the target cleaning stage includes a main wash stage; in the main wash stage, the step of injecting water into the drum to a preset lint-removing water level according to the target cleaning stage, and controlling the drum to alternately rotate forward and backward at the preset angle α for a preset duration includes:

[0018] The outer cylinder is filled with water to the first preset hair removal washing water level H1 in one go;

[0019] The control drum rotates alternately in both forward and reverse directions at a first preset rotation angle α1 for a first preset duration T1.

[0020] Drain the water from inside the drum;

[0021] Wherein, α1 = β * n1, where β is the central angle between two adjacent lifting ribs, β = 360° / m, m is the number of lifting ribs, and n1 is a positive integer greater than or equal to 1.

[0022] Alternatively, the first lint removal wash water level H1 can be a low water level, where the garment absorbs water fully within the first lint removal wash water level H1, and the first lint removal wash water level H1 is lower than the highest point of the garment.

[0023] Optionally, the target cleaning stage may include a rinsing stage, wherein the hair removal cleaning strategy during the rinsing stage includes:

[0024] In the first stage, water is injected into the outer cylinder to the second hair removal washing water level H2, and the drum is controlled to rotate alternately in both forward and reverse directions at a second preset rotation angle α2 for a second preset duration T2.

[0025] In the second stage, water is injected into the outer cylinder to the third de-hairing water level H3, and the drum is controlled to rotate alternately in the forward and reverse directions at the third preset rotation angle α3 for a third preset time T3 to discharge the water and lint from the outer cylinder.

[0026] Wherein, α2 = β * n2, where β is the central angle between two adjacent lifting ribs, β = 360° / m, m is the number of lifting ribs, and n2 is a positive integer greater than or equal to 1;

[0027] The angle α3 can be any angle.

[0028] Optionally, the third hair removal wash water level H3 is higher than the second hair removal wash water level H2.

[0029] The second lint removal wash water level H2 is a low water level. After the clothes have fully absorbed water in the second lint removal wash water level H2, the second lint removal wash water level H2 is lower than the highest point of the clothes.

[0030] The third lint removal wash water level H3 is a high water level. After the clothes have fully absorbed water in the third lint removal wash water level H3, the third lint removal wash water level H3 completely submerges the clothes.

[0031] Secondly, this application provides a washing device, including an outer drum and a drum rotatably disposed inside the outer drum. The inner sidewall of the drum is provided with a plurality of lifting ribs that rotate with the drum in a circumferentially uniform manner. The lifting ribs are provided with lifting rib cavities inside. The lifting ribs are provided with a hair removal structure and a through hole on the sidewall facing the drum cavity to allow water and hair in the drum cavity to flow into the lifting rib cavity.

[0032] The washing equipment performs the dander cleaning control method described above.

[0033] Alternatively, the end of the through hole away from the lifting rib cavity is designated as the first port, and the end facing the lifting rib cavity is designated as the second port, wherein the diameter of the first port is larger than the diameter of the second port.

[0034] The hair removal structure has a scraping end that protrudes from the wall surface of the sidewall;

[0035] The hair removal structures and the through holes are alternately arranged in the width direction of the sidewall.

[0036] Alternatively, the above-mentioned solution may further include a partition inside the lifting rib cavity, the partition being located between the two side walls.

[0037] Compared with the prior art, this application provides a method and washing equipment for controlling dander cleaning, which has the following beneficial effects:

[0038] 1. The inner wall of the roller is uniformly provided with multiple lifting ribs. During the lint removal process, the roller is first rotated so that one of the lifting ribs is located at the bottom of the roller. The rotation position of the roller at this time is used as the reference position. The roller is controlled to rotate alternately in both forward and reverse directions at a preset rotation angle α. The preset angle α is the rotation angle of the roller relative to the reference position, α = β * n, where 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. This ensures that there is always one lifting rib at the bottom. With a suitable water level, the clothes are lifted by the rotating roller and the lifting rib and fall onto another lifting rib, increasing the number of times the lifting rib beats and rubs the clothes, so as to remove the lint adhering to the clothes.

[0039] 2. Set the water level for the lint removal wash. The water level should be lower during the main wash and then higher during the rinsing wash. The lower water level helps to tumble the clothes and remove lint, while the higher water level keeps the lint floating on the surface and preventing it from falling back onto the clothes.

[0040] 3. The lifting ribs are equipped with raised hair removal structures and funnel-shaped through holes. Hair is scraped into the through holes or peeled off clothing by the raised hair removal structures and flows into the lifting ribs with the water flow, and is not easy to flow out. There is an opening at the bottom of the lifting ribs, and water with hair and debris flows through the opening below to the space between the inner and outer cylinders. Attached Figure Description

[0052] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0053] Please see Figure 1 As shown, this application provides a lint cleaning control method, which is applied to a drum washing machine. The drum washing machine includes an outer drum and a drum rotatably disposed inside the outer drum. The inner side wall of the drum is evenly provided with a plurality of lifting ribs that rotate with the drum. The lifting ribs are formed with lifting rib cavities inside. The lifting ribs are provided with lint removal structures and through holes on the side wall facing the drum cavity, which allow water and lint in the drum cavity to flow into the lifting rib cavity.

[0054] The dandruff cleaning control method, in the process of controlling the roller to alternately rotate forward and reverse at a preset dandruff removal water level for dandruff cleaning, first rotates the roller so that one of the lifting ribs is located at the bottom of the roller, and uses the rotation position of the roller at this time as a reference position to control the roller to alternately rotate forward and reverse at a preset rotation angle α.

[0055] Wherein, the preset angle α is the rotation angle of the roller relative to the reference position, α=β*n, where 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, if the inner wall of the roller is uniformly provided with 3 lifting ribs in the circumference, i.e., m=3, then 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 this lint cleaning control method is to increase the number of times the lifting ribs rub against the clothing, so as to remove the lint adhering to the clothing. Therefore, in the lint cleaning process, the position of the lifting ribs is first adjusted by rotating the roller so that one of the lifting ribs is located at the bottom of the roller. After the lifting rib position is adjusted, the roller is controlled to alternately rotate forward and reverse at a preset rotation angle α, using the current rotation position of the roller as a reference position.

[0058] As the roller rotates alternately in both forward and reverse directions at a preset rotation angle α, the lifting ribs at the bottom of the roller lift the clothes to a high position and then drop them. Due to the design of the rotation angle α, there is always a lifting rib at the bottom when the roller stops. When the clothes fall, they will contact the lifting rib at the bottom. Then the roller reverses the angle α, and the clothes are lifted to a high position again and then drop. The clothes will contact the lifting rib at the bottom of the roller again. This process is repeated for a preset time. The clothes are continuously pounded and in contact with the lifting ribs, which removes the hair attached to the clothes.

[0059] In one embodiment, the dandruff cleaning control method provided in this application further includes:

[0060] Obtain the target cleaning stage for dander removal;

[0061] Determine and execute the hair removal strategy based on the target cleaning stage;

[0062] in,

[0063] Different cleanup strategies are used for different target cleanup phases;

[0064] Different cleaning strategies correspond to different hair removal cycles and / or hair removal water levels and / or preset hair removal duration and / or preset rotation angle.

[0065] Specifically, the step of determining and executing a hair removal strategy based on the target cleaning stage includes the following control steps:

[0066] According to the target cleaning stage, water is injected into the drum to the preset lint removal washing water level;

[0067] The roller is controlled to rotate alternately in both forward and reverse directions at the preset angle α for a preset duration.

[0068] like Figure 1As shown, specifically, the target cleaning stage includes a main wash stage. In the main wash stage, the step of injecting water into the drum to a preset lint-removing water level according to the target cleaning stage, and controlling the drum to alternately rotate forward and backward at the preset angle α for a preset duration includes:

[0069] S1: Inject water into the outer cylinder once to the first preset depilatory wash water level H1.

[0070] The first lint removal wash water level H1 is a low water level. The first lint removal wash water level H1 is a water level that is slightly higher than the water level required to wet the clothes. After the clothes have fully absorbed water in the first lint removal wash water level H1, the first lint removal wash 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 in both forward and reverse directions at a first preset rotation angle α1, and start timing; wherein, α1 = β * n1, where β is the central angle between two adjacent lifting ribs, β = 360° / m, m is the number of lifting ribs, and n1 is a positive integer greater than or equal to 1.

[0072] When three lifting ribs are evenly spaced on the inner wall of the roller, i.e., m=3, the central angle β between two adjacent lifting ribs is 120°. The preset angle α1 can be an integer multiple of 120° such as 120°, 240°, 360°, 480°, etc.

[0073] As the roller rotates alternately in both forward and reverse directions at a preset rotation angle α1, the lifting ribs at the bottom of the roller lift the clothes to a high position and then drop them. Due to the design of the rotation angle α1, there is always a lifting rib at the bottom when the roller stops. When the clothes fall, they will contact the lifting rib at the bottom. Then the roller reverses the angle α1, and the clothes are lifted to a high position again and then drop. The clothes will contact the lifting rib at the bottom of the roller again. This process is repeated for a preset time. The clothes are continuously pounded and in contact with the lifting ribs, which removes the hair attached to the clothes.

[0074] S3: When the first preset time T1 is reached, the water inside the drum will be discharged outward.

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

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

[0077] S4: Inject water into the outer cylinder to the second depilatory washing water level H2.

[0078] The second lint removal wash water level H2 is a low water level. The second lint removal wash water level H2 is a water level that is slightly higher than the water level required to wet the clothes. After the clothes have fully absorbed water in the second lint removal wash water level H2, the second lint removal wash 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 lint removal wash water level H2 can be the same as the first lint removal wash water level H1.

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

[0080] When three lifting ribs are evenly spaced on the inner wall of the roller, i.e., m=3, the central angle β between two adjacent lifting ribs is 120°. The preset angle α2 can be an integer multiple of 120° such as 120°, 240°, 360°, 480°, etc.

[0081] As the roller rotates alternately in both forward and reverse directions at a preset rotation angle α2, the lifting ribs at the bottom of the roller lift the clothes to a high position and then drop them. Due to the design of the rotation angle α2, there is always a lifting rib at the bottom when the roller stops. When the clothes fall, they will contact the lifting rib at the bottom. Then the roller reverses the angle α2, and the clothes are lifted to a high position again and then drop. The clothes will contact the lifting rib at the bottom of the roller again. This process is repeated for a preset time. The clothes are continuously pounded and in contact with the lifting ribs, which removes the hair attached to the clothes.

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

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

[0084] The third lint removal wash water level H3 is a high water level. After the clothes have fully absorbed water in the third lint removal wash water level H3, the third lint removal wash water level H3 completely submerges the clothes.

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

[0086] At this time, the normal washing mode is performed, and the rotation-stop ratio is set directly without considering the drum rotation angle. Therefore, α3 can be any angle.

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

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

[0089] The lint cleaning control method provided in this application increases the number of times the lifting ribs tumble and rub the clothes to remove the lint adhering to the clothes. During the alternating forward and reverse rotation of the roller at a preset rotation angle α, the lifting ribs located at the bottom of the roller lift the clothes to a high position and then drop them. Due to the design of the rotation angle α, there is always one lifting rib at the bottom when the roller stops. When the clothes fall, they will contact the lifting rib at the bottom. Then the roller reverses the angle α, and the clothes are lifted to a high position again and then fall. The clothes will contact the lifting rib at the bottom of the roller again. This process is repeated for a preset time, and the clothes are continuously tumbled and in contact with the lifting ribs, thus removing the lint adhering to the clothes.

[0090] See also Figures 2-6 As shown in the figure, B represents clothing. This application provides a washing device, including an outer drum 3, a roller 2 coaxially arranged inside the outer drum 3, and the aforementioned lifting ribs 1. A plurality of the lifting ribs 1 are uniformly fixed to the inner wall of the roller 2.

[0091] When the washing equipment is in operation, the first lifting rib 1 lifts the clothes. When the lifting rib 1 rotates to a certain angle, the clothes fall onto the second lifting rib 1. When the washing equipment is stopped, any of the lifting ribs 1 is located on the inner wall of the bottom end of the drum 2.

[0092] See also Figure 5 As shown, the drum 2 has three lifting ribs 1 inside. Each time the washing machine stops, there will always be one lifting rib 1 at the bottom. When rotating, the lifting rib lifts the clothes to a high position and then drops them. Then it reverses 120°·n, where n is a positive integer greater than or equal to 1. The clothes are lifted to a high position again and then drop them. This ensures that there is always one lifting rib at the bottom each time the machine stops. When the clothes fall, they will contact the lifting rib at the bottom. This process continues for a period of time. The clothes are continuously tumbled and in constant contact with the lifting ribs, which removes the hair adhering to the clothes.

[0093] See also Figure 5 As shown, a gap is formed between the outer cylinder 3 and the roller 2;

[0094] The roller 2 is provided with a through hole corresponding to the opening 15. The through hole 14, the lifting rib cavity, the through hole 14, the through hole and the gap are connected in sequence. Hair is scraped into the through hole 14 or peeled off the clothes by the raised hair removal structure 13 and flows into the lifting rib 1 with the water flow. The hair that enters the lifting rib 1 with the water flow will be discharged from the lifting rib 1 through the opening 15 and discharged into the gap between the roller 2 and the outer cylinder.

[0095] The roller 2 is further provided with a threaded hole corresponding to the inner threaded ring 17;

[0096] The screw passes through the inner threaded ring 17 and the threaded hole to fix the lifting rib 1 to the roller 2.

[0097] The lifting rib 1 includes a housing 11, which may be triangular prism-shaped. The housing 11 has two opposing side walls 12, and a mounting surface and a top surface located between the two side walls 12. The housing 11 is provided with a lifting rib cavity with an opening facing the mounting surface.

[0098] The outer walls of both side walls 12 are provided with multiple raised lint removal structures 13. The multiple lint removal structures 13 are evenly distributed, and the length direction of the lint removal structures 13 is perpendicular to the rotation direction of the roller 2. Through the design of multiple lint removal structures 13, the beating and friction on the clothes are increased, which is conducive to the removal of lint.

[0099] The outer walls of both sidewalls 12 are provided with multiple through holes 14, which are evenly distributed. The through holes 14 are connected to the lifting rib cavity. Hair is scraped into the through holes 14 by the raised hair removal structure 13 or peeled off the clothing and flows into the lifting rib 1 with the water flow.

[0100] The multiple hair removal structures 13 and the multiple through holes 14 are alternately arranged in the width direction of the sidewall 12.

[0101] Please see Figure 3 and Figure 4 As shown, the inner wall of the lifting rib cavity is provided with several openings 15, which can be square or round. The open end of the opening 15 faces the roller. Hair that enters the lifting rib 1 with the water flow will be discharged from the lifting rib 1 through the opening 15 and discharged into the gap between the roller 2 and the outer cylinder.

[0102] Furthermore, the through hole 14 is a tapered hole, and the inner diameter of the outer end of the through hole 14 is larger than the inner diameter of the inner end of the through hole 14. Through the design of the tapered through hole 14, the hair flowing into the lifting rib 1 with the water flow is less likely to flow out.

[0103] Furthermore, a partition 16 is provided inside the lifting rib cavity. The partition 16 is located between the two side walls 12 and in the middle of the lifting rib 1. Water with lint flows in from one side wall 12 and will not flow out from the other side due to the obstruction of the partition 16.

[0104] Please see Figure 3 and Figure 4 As shown, the housing 11 is provided with an inner threaded ring 17. The inner threaded ring 17 is a tube with an inner thread on its inner wall that matches the screw. One end of the inner threaded ring 17 starts from the side wall 12 and the other end extends into the lifting rib cavity and toward the roller, so as to facilitate fixing the lifting rib 1 to the roller 2.
