Description

Technical Field

[0001] The present invention belongs to the technical field of washing equipment, and specifically, relates to a control method for a washing machine and a washing machine. Background Art

[0002] In recent years, with the continuous improvement of people's living standards and consumption concepts, in addition to pursuing comfort and beauty in dressing, people also pay more attention to the materials of clothes. A washing machine is an indispensable household appliance in contemporary families, and some basic washing functions of the washing machine can no longer meet the current users' needs. Currently, the main water inlet of the washing machine usually flows into the bottom of the outer barrel through the window gasket, and the water level gradually rises until it reaches the water level set by the program and then stops filling. When washing clothes that are large in volume, light in weight, and have a small waterproof load, such as washing down jackets, the clothes will float on the water surface and cannot be immersed in water for a long time, affecting the user experience. Therefore, ensuring that clothes that are easy to float (such as down jackets) can be fully soaked during washing, improving the washing rate, and enhancing the user experience have become urgent problems to be solved.

[0003] Chinese Patent with application number 202211624281.9 discloses a control method, device and washing machine for a washing machine. The method includes: when washing clothes made of difficult-to-absorb water materials, during the stage of soaking the clothes, the inner barrel of the washing machine rotates at a first speed, so that the clothes to be washed rotate against the inner wall of the inner barrel, and water is sprayed into the inner barrel for soaking in a spray water inlet manner; after the stage of soaking the clothes ends, it enters the stage of washing the clothes, and the inner barrel of the washing machine rotates at a second speed, and water is sprayed into the inner barrel for washing in a spray water inlet manner; the first speed is greater than the second speed. This patent makes the clothes rotate against the wall and sprays water on the clothes to soak them during the soaking stage of the clothes, but to make down jackets rotate against the wall, a greater rotation speed and longer time are required, increasing the user's washing cost. Therefore, this means of submerging clothes is not the user's first choice.

[0004] In view of this, the present invention is specifically proposed. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art, and provide a control method for a washing machine and a washing machine, which can quickly soak down jackets and other clothes that are easy to float during the soaking process, improve the washing rate, and effectively enhance the user experience.

[0006] To solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0007] A control method for a washing machine includes the following steps:

[0008] S1. Obtain the information of the clothes to be washed, and judge whether the clothes to be washed include target clothes;

[0009] S2. If so, execute the agitation soaking mode, and control the washing tub to rotate forward and backward alternately to agitate the water flow so as to immerse the target clothing.

[0010] Further, the target clothing is floating-prone clothing;

[0011] Collect the image of the clothing to be washed through the image acquisition module, compare it with the preset image, and obtain the target clothing;

[0012] Or, collect the weight and height of the clothing through the weight and height acquisition module, compare them with the preset weight and height ratio relationship, and obtain the target clothing.

[0013] Further, in step S2, after entering the agitation soaking mode, control the washing tub to rotate forward and backward alternately after the water level of the washing machine reaches the preset water level.

[0014] Further, after entering the agitation soaking mode, control the washing machine to fill water according to the first water filling program, and the first water filling program is set to spray water from multiple angles at the top of the washing machine, fill water at the bottom of the washing tub, and circulate water from the bottom of the washing tub to the top.

[0015] Further, when it is determined that the clothing to be washed does not contain the target clothing, execute the normal soaking mode, and control the washing machine to fill water according to the second water filling program, and the second water filling program is set to fill water at the bottom of the washing tub.

[0016] Further, after step S2, there is also step S3. Determine whether the target clothing is completely immersed. If so, start the washing program. If not, repeat step S2 for N times.

[0017] Further, whether the target is completely immersed is obtained by comparing the height of the clothing before and after water inlet. If the height difference of the clothing before and after water inlet meets the set condition, it is determined to be completely immersed.

[0018] Further, the agitation soaking mode includes controlling the washing tub to rotate forward by a first set angle and then rotate backward by a second set angle alternately until the set time or set number of times. When rotating forward and backward, it accelerates to the set angle at the set acceleration and then decelerates to stop at the set deceleration.

[0019] Further, the first set angle is 80 - 100°, the second set angle is 80 - 100°, the set acceleration is 120 - 150 m / s², and the set deceleration is 900 - 1100 m / s².

[0020] The basic concept of another technical solution of the present invention is:

[0021] A washing machine adopts the control method as described above.

[0022] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0023] (1) By obtaining the clothing material information and controlling the motion parameters of the washing drum, the present invention can fully immerse the target clothing, quickly soak down jackets, improve the clothing washing rate, and effectively enhance the user experience.

[0024] (2) The present invention adopts a more convenient and fast immersion method, effectively improving the clothing washing rate, without the need to increase additional costs, reducing the user's cost, reducing the power consumption of the washing machine, and saving energy while improving the clothing washing rate.

[0025] (3) The present invention replaces the water inlet method in the traditional washing process of down jackets, adopts spray water inlet and agitated flushing, quickly soaks down jackets, and can solve the problem that down fabrics are not easily fully soaked and always float on the surface of the clothing during the traditional washing process of down jackets, resulting in a low clothing washing rate.

[0034] Embodiment 1

[0035] It should be noted that due to the different materials of clothes, some clothes are prone to floating on the water surface during washing and are not easily wetted by water. The clothes that are easy to float are characterized by large volume, light weight, waterproof on the surface of the clothes, but the internal material of the clothes is not difficult to absorb water.

[0036] The following embodiments mainly take clothes containing down-like materials as examples for illustration, and the clothes made of other materials that are easy to float are also applicable to the technical solutions of the present invention.

[0037] In the related solutions, when the washing machine washes down jackets, the main water inlet usually flows into the bottom of the outer drum through the window gasket, and the water surface gradually rises until it reaches the water set by the program and then stops the water inlet.

[0038] It should be noted that this water inlet scheme has no impact on clothes that are easy to absorb water or when the load is large. However, for clothes that are not easy to absorb water and have a small load, such as when washing down jackets, the clothes will float on the water surface and cannot be immersed in water for a long time.

[0039] This embodiment provides a control method for a washing machine, including the following steps:

[0040] S1. Obtain the information of the clothes to be washed and judge whether the clothes to be washed contain target clothes;

[0041] S2. If so, execute the agitation and soaking mode, and control the washing drum to rotate forward and backward alternately to agitate the water flow so as to immerse the target clothes.

[0042] Furthermore, the target clothes are clothes that are easy to float;

[0043] Collect the images of the clothes to be washed through the image acquisition module, compare them with the preset images, and obtain the target clothes.

[0044] Or, collect the weight and height of the clothes through the weight and height acquisition module, compare them with the preset weight and height ratio relationship, and obtain the target clothes.

[0045] Furthermore, the weight and height acquisition module includes a weight sensor and a height sensor arranged in the washing tub. The weight sensor obtains the weight of the target clothes, and the height sensor obtains the height of the target clothes.

[0046] Furthermore, the image acquisition module includes a camera arranged in the washing tub to collect the images of the clothes to be washed and upload them to the controller.

[0047] Further, in step S2, after entering the agitation soaking mode, when the water level of the washing machine reaches the preset water level, then control the washing tub to rotate forward and backward alternately.

[0048] Furthermore, a water level sensor is arranged in the washing tub. If the water level sensor detects the water level of the washing machine, it uploads it to the controller and then controls the washing tub to rotate forward and backward alternately. It should be noted that by controlling the washing tub to rotate forward and backward alternately after the water level of the washing machine reaches the preset water level, a more intense agitation water flow can be obtained, and the target clothes can be quickly wetted.

[0049] Further, after entering the agitation soaking mode, control the washing machine to fill water according to the first water filling program, and the first water filling program is set to spray water from multiple angles at the top of the washing machine, fill water at the bottom of the washing tub, and circulate water from the bottom of the washing tub to the top.

[0050] Furthermore, the circulation pump pumps the water flow at the bottom of the washing tub into the nozzle at the top of the washing tub, and through repeated circulating spray water filling, the down jacket is fully wetted.

[0051] Further, when it is determined that the clothes to be washed do not contain the target clothes, execute the normal soaking mode, and control the washing machine to fill water according to the second water filling program, and the second water filling program is set to fill water at the bottom of the washing tub.

[0052] Further, there is also step S3 after step S2. Determine whether the target clothes are completely submerged. If so, start the washing program. If not, repeat step S2 for N times.

[0053] Further, whether the target is completely submerged is obtained by comparing the height of the clothes before and after water filling. If the height difference of the clothes before and after water filling meets the set conditions, it is determined that it is completely submerged.

[0054] Further, after the agitation immersion mode, the height of the target clothing is measured by a height sensor provided in the washing tub and compared with the height of the target clothing detected before water inlet. If the set height difference is satisfied, it is determined that the target clothing is completely immersed, and the agitation immersion mode can be ended and the washing of the target clothing can be started.

[0055] Further, the agitation immersion mode includes controlling the washing tub to rotate forward by a first set angle and then rotate backward by a second set angle alternately until a set time or a set number of times. When rotating forward and backward, it accelerates to the set angle at a set acceleration and then decelerates to stop at a set deceleration.

[0056] Furthermore, by controlling the washing tub to rotate forward and backward alternately for T1 time or S' times, the agitated water flow is used to quickly wet the target clothing. In this embodiment, when the washing tub rotates forward, it rotates to 90 degrees at a set acceleration and then rotates to 100 degrees at a set deceleration. Correspondingly, when the washing tub rotates backward, it rotates to 90 degrees at a set acceleration and then rotates to 100 degrees at a set deceleration.

[0057] Through the rotation angle, rotation acceleration and deceleration in this embodiment, a more intense agitated water flow can be generated to quickly wet the target clothing, achieve the immersion effect, and improve the washing rate.

[0058] Further, the first set angle is 80 - 100°, the second set angle is 80 - 100°, the set acceleration is 120 - 150 m / s2, and the set deceleration is 900 - 1100 m / s2.

[0059] Furthermore, in this embodiment, when rotating the first set angle and the second set angle, it rotates at a set acceleration and a set deceleration at the same time, which can quickly agitate the water flow, fully immerse the down jacket, and improve the user experience.

[0060] Embodiment 2

[0061] This embodiment provides a washing machine, including:

[0062] An acquisition unit for acquiring target clothing information and uploading it to the control unit;

[0063] A water inlet unit, the water inlet unit is connected to the control unit, and the water inlet unit controls the water inlet mode according to the laundry program;

[0064] It further includes:

[0065] A control unit, the control unit determines whether the target clothing is completely wet through the target clothing information. If so, it enters the washing program. If not, it controls the immersion unit to repeat the program once;

[0066] The immersion unit is connected to the control unit. The immersion unit controls the washing tub to rotate and agitate with water flushing at different angles and / or different acceleration and deceleration rates according to the water level in the washing tub, so as to fully immerse the target clothing.

[0067] It should be noted that by obtaining the clothing material and controlling the motion parameters of the washing tub, the present invention can fully immerse the target parameters, quickly wet down jackets and improve the washing rate, effectively enhancing the user experience.

[0068] Further, the acquisition unit includes a weight sensor and a height sensor disposed in the washing tub. The weight sensor obtains the weight of the target clothing, and the height sensor obtains the height of the target clothing. The acquisition unit uploads the weight and height of the target clothing to the control unit.

[0069] Furthermore, the control unit is set as a controller.

[0070] Preferably, the acquisition unit can also be set as an image sensor.

[0071] Preferably, several image sensors are arranged inside the washing tub in this embodiment. The image sensors take pictures of the target clothing in the washing tub at different angles. At the same time, the image sensors are connected to the controller, and the image sensors upload the obtained clothing information to the controller.

[0072] It should be noted that the way for the acquisition unit to obtain clothing information is not limited to the way provided in this embodiment.

[0073] Further, the water inlet unit includes a spray device disposed at the top of the washing tub and a circulation pump connected to the bottom of the washing tub. One end of the spray device is connected to the water inlet pipe, and the other end of the spray device is connected to the circulation pump. The spray device is also provided with several nozzles at different angles facing the bottom of the washing tub.

[0074] Furthermore, the nozzles disposed at different angles at the top of the washing tub facing the bottom of the washing tub can spray the inlet water at different positions of the clothes, so as to quickly immerse them.

[0075] Furthermore, the circulation pump pumps the water flow at the bottom of the washing tub into the nozzles at the top of the washing tub, and through repeated cyclic spraying of the inlet water, the down jacket is fully wetted.

[0076] It is worth noting that the present invention adopts the top spraying method for water inlet during the water inlet stage of the down jacket, ensuring that the down jacket is fully moistened and enabling the down jacket to quickly absorb water.

[0077] This embodiment realizes the circulation of the water flow in the washing tub, so that the water flow sprays from the bottom to the top onto the down jacket in the washing tub, further wetting the down jacket, effectively soaking the down jacket thoroughly, and improving the washing effect on the down jacket.

[0078] Further, the control unit is set as a controller, and the controller is configured to obtain a corresponding laundry program based on the target clothing information. The laundry program includes a water inlet program and a soaking program. The water inlet program is set to spray water into the washing machine from the top and circulate water into the washing tub from the bottom. The soaking program is set to soak the target clothing by agitating and flushing water in the washing tub.

[0079] Further, the immersion unit controls the washing tub to rotate at a set speed in a positive angle within a set range, then rotate in a negative angle within a set range, and at the same time rotate with a set acceleration and deceleration.

[0080] It should be noted that in this embodiment, agitating and flushing water is adopted, that is, during the water inlet process, the washing tub is controlled to rotate at a positive angle within a set range, then rotate at a negative angle within a set range, and at the same time rotate with a set acceleration and deceleration to form agitating and flushing water, quickly wetting down jackets and other clothing, which can solve the problem that down fabrics are not easily completely wetted during the washing process of traditional down clothing and always float on the surface of the clothing.

[0081] Embodiment III

[0082] As Figure 1 shown, this embodiment provides a control method for a washing machine. The control method of the washing machine may include: Steps S1 to S4:

[0083] S1. Obtain the target clothing information;

[0084] S2. Select a corresponding laundry program based on the target clothing information, and determine whether the target clothing belongs to clothing that is easy to float. If so, execute the first water inlet program; if not, execute the second water inlet program;

[0085] S3. Determine whether the water level in the washing tub reaches a preset water level. If so, execute the agitating program; if not, execute the first water inlet program;

[0086] S4. Determine whether the target clothing is completely immersed. If so, start washing; if not, execute the agitating program.

[0087] Further, the target clothing information includes one or more of the clothing weight and the clothing height, and the relationship between the clothing height and the clothing weight of clothing that is easy to float is prestored in the controller.

[0088] Furthermore, obtaining the target clothing information can be understood as obtaining the target clothing height and the target clothing weight, and determining whether the target clothing belongs to clothing that is easy to float through the relationship between the target clothing height and the target clothing weight prestored in the controller.

[0089] Further, the first water inlet program is set to spray water into the washing drum from the top, inlet water from the bottom, and recycle water from the bottom to the top, and the second water inlet program is set to inlet water into the washing drum from the bottom.

[0090] Furthermore, if the target clothing belongs to the clothing that is easy to float, due to the characteristics of the clothing that is easy to float itself, the controller controls the water inlet unit to start the first water inlet program. At this time, the washing drum uses top spray water inlet, bottom water inlet, and bottom recycle to top water inlet to quickly and fully wet the down jacket.

[0091] Furthermore, if the target clothing does not belong to the clothing that is easy to float, the controller controls the water inlet unit to start the second water inlet program. At this time, the washing drum uses bottom water inlet, and the water flows through the window gasket into the bottom of the outer drum, and the water surface gradually rises until it reaches the water level set by the program and then stops water inlet.

[0092] It should be noted that this water inlet scheme has no impact on the clothing that is easy to absorb water or when the load is large, ensuring the washing effect and reducing the user cost.

[0093] Further, the agitation program controls the washing drum to rotate at a positive angle or a negative angle, and at the same time uses different acceleration or deceleration to make the washing water agitate in the washing drum, and fully immerse the target clothing through agitation flushing.

[0094] Preferably, if the water level in the washing drum reaches the preset water level, the controller controls the immersion unit to execute the agitation program, controls the washing drum to rotate at a set speed, and the set speed is preferably 30 - 50 rpm, and rotates towards the positive angle. The range of the positive angle is preferably between 80 degrees and 100 degrees. Then, it controls the washing drum to rotate at the set speed and rotate towards the negative angle. The range of the positive angle is preferably between 80 degrees and 100 degrees. At the same time, the acceleration of the washing drum is preferably 120 - 150 m / s2, and the deceleration is preferably 900 - 1100 m / s2.

[0095] Further, the immersion effect of the target clothing is obtained by comparing the height and weight of the clothing before and after water inlet acquired by the acquisition unit.

[0096] Furthermore, after executing an agitation program once, this embodiment provides detection of the immersion effect of the target clothing, obtains the current height of the target clothing, and compares it with the height of the target clothing before water inlet through the controller to determine whether the target clothing is completely immersed.

[0097] The above are only the preferred embodiments of the present invention, and there is no limitation to the present invention in any form. Although the present invention has been disclosed as above with the preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art of this patent can make some changes or modifications to equivalent embodiments with equivalent changes by using the technical content prompted above within the scope of the technical solution of the present invention. The implementation schemes in the above embodiments can also be further combined or replaced. However, as long as it does not depart from the technical content of the present invention, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention still fall within the scope of the present invention's solution.
