Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of washing machines, and particularly relates to a control method and device of a washing machine and the washing machine. BACKGROUND

[0002] In recent years, with the continuous improvement of people's living standards and consumption concepts, people pay more attention to the material of clothes in addition to comfort and beauty in dressing. The washing machine is an indispensable household appliance in modern families, and some basic washing of the washing machine cannot meet the current user's needs, so most of the current market's mid-to-high-end washing machines meet the washing needs of different users. However, these washing machines still have some problems that cannot effectively wash clothes made of high-end materials, which affects the user experience. For example, clothes containing wool are not easy to absorb water and are prone to felting. The existing method of washing clothes containing wool may result in that some parts of the clothes are not fully wet and clean or the clothes are significantly shrunk at the end of the washing. Therefore, a special washing method is needed to ensure that the clothes made of difficult-to-absorb materials (such as wool) are fully soaked when washing, improve the cleaning rate, reduce the shrinkage of the clothes, and improve the user experience.

[0028] To make the objects, technical solutions, and advantages of the present application clearer, the following will be a clear and complete description of the technical solutions of the present application in combination with specific embodiments of the present application and corresponding drawings. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0029] Due to different materials of clothes, some clothes are difficult to absorb water during washing and are not easy to be soaked by water. There are many types of clothes with difficult-to-absorb materials, such as clothes containing wool materials, clothes containing chemical fiber materials such as polyester, nylon, or nylon, clothes containing down materials, and clothes containing natural silk materials. The following embodiments mainly take clothes containing wool materials as representatives for illustration, and other clothes with difficult-to-absorb materials are also applicable to the technical solutions of the present application.

[0030] Most washing machines in related solutions use the main washing valve to let in water when washing clothes with wool materials, and rely on heating the water temperature or continuously beating to soak the wool materials during the washing process. A large amount of time is needed in this process. Due to the influence of the wool material itself, it is not easy to absorb water, and the wool coat is in a floating state and cannot be soaked during the main washing process. There is a phenomenon that some positions of the clothes are not soaked by water after washing, which leads to poor washing effect of wool and troubles users. Wool clothes are easily affected by water temperature and mechanical force during the washing process, and in the case of large mechanical force and water temperature, wool felt will be caused, clothes will become small, and people cannot wear them completely, which causes economic loss to users.

[0031] Therefore, the present application provides a control method of a washing machine, specifically a method for implementing the washing control logic of a washing machine. The present application replaces the water inlet mode in the traditional wool clothes washing process and adopts spraying water inlet, that is, during the water inlet process, the wool runs along the wall and sprays water at the same time. In this process, the water inlet of the spraying port will directly spray to the surface of the wool in the barrel. Under the action of centrifugal force during rotation, the water mist attached to the surface of the wool will penetrate into the inside of the wool, and the wool will be soaked. This can solve the problem that wool fabric is not easy to absorb water and always floats on the surface of the clothes during the traditional wool washing process, which leads to low washing rate of the clothes.

[0032] The present application adopts the spraying mode to water in the water feeding stage of wool, and the wool fabric is run against the wall in the process, and the spraying valve sprays water to ensure that the wool fabric is fully wetted. The traditional mechanical force and high temperature heating can cause serious shrinkage of wool. The wall-attached water feeding mode can make the wool fabric quickly absorb water, and the wall-attached running in the water feeding process reduces the relative movement of the clothes to solve the problem of clothes shrinkage.

[0033] According to the embodiment of the present application, a control method of a washing machine is provided, the washing machine has a spraying device, the spraying device has a spraying valve, the spraying valve is used to control the opening and closing of the spraying device, as shown in Figure 1 The flowchart of an embodiment of the control method of the washing machine of the present application is shown. The control method of the washing machine can include steps S110 to S130.

[0034] At step S110, the material of the clothes to be washed in the washing machine is obtained, and the weight of the clothes to be washed is obtained.

[0035] At step S120, in the case that the material of the clothes to be washed is a difficult water-absorbing material, the washing parameters of the clothes to be washed are determined according to the weight of the clothes to be washed.

[0036] At step S130, according to the washing parameters of the clothes to be washed, a preset difficult water-absorbing material clothes washing program is started; the difficult water-absorbing material clothes washing program includes a difficult water-absorbing material clothes water feeding and soaking stage; correspondingly, the washing parameters of the clothes to be washed include a first washing parameter of the difficult water-absorbing material clothes water feeding and soaking stage. The first washing parameter includes a first rotating speed; in the difficult water-absorbing material clothes water feeding and soaking stage, the spraying valve is controlled to be opened, and the motor of the washing machine is controlled to rotate at the first rotating speed, so that the clothes to be washed are attached to the inner wall of the inner drum of the washing machine and rotate with the inner drum, and are soaked in the process of being sprayed with water on the inner wall of the inner drum of the washing machine after the spraying device is opened.

[0037] The present application changes the traditional mode of water feeding for clothes made of wool and other difficult water-absorbing materials, and through long-term test observation of the state of different clothes in the washing process by adjusting the rotating speed of the inner drum of the washing machine, it is found that the clothes can run against the wall. In this embodiment, the clothes are sprayed with water while running against the wall, and the wool clothes always run against the inner wall of the inner drum of the washing machine in the whole water feeding and spraying process. The spraying valve directly sprays water to the surface of the wool clothes running against the wall in the inner drum. In the rotating process, the water mist attached to the surface of the wool is accelerated to penetrate into the inside of the wool fabric due to the centrifugal force, so as to achieve the effect of rapid wetting and improve the washing effect.

[0038] In the main washing water inlet process, the woolen clothes are run against the wall, so that there is no relative movement between clothes and clothes, and between clothes and inner cylinder. There is no large mechanical force and action force in this process, and heating is not required in the main washing stage. Normal temperature washing can reduce the need for mechanical force to beat water waves to wet the clothes, and the need for heating to quickly absorb water by the clothes. In this way, the wool shrinkage phenomenon caused by mechanical force and temperature can be reduced.

[0039] In some embodiments, the difficult water-absorbing material clothes washing program further comprises: a difficult water-absorbing material clothes water inlet main washing stage; and the washing parameters of the clothes to be washed comprise: second washing parameters of the difficult water-absorbing material clothes water inlet main washing stage; the second washing parameters comprise: a second rotating speed; in the difficult water-absorbing material clothes water inlet main washing stage, the motor of the washing machine is controlled to rotate at the second rotating speed, and the spraying device is controlled to be intermittently opened, so that the clothes to be washed are washed at the second rotating speed, and are further wetted in the process of being sprayed to the inner wall of the inner cylinder by the spraying water after the spraying device is intermittently opened; and the first rotating speed is greater than the second rotating speed.

[0040] In step S120, in the case that the material of the clothes to be washed is a difficult water-absorbing material, the washing parameters of the clothes to be washed are determined according to the weight of the clothes to be washed, comprising:

[0041] In the case that the material of the clothes to be washed is a difficult water-absorbing material, the corresponding relationship between the set weight and the set washing parameters is determined, and the set washing parameters corresponding to the set weight same as the weight of the clothes to be washed in the corresponding relationship are determined as the washing parameters of the clothes to be washed.

[0042] In the stage of soaking clothes, the inner cylinder of the washing machine rotates at a first rotating speed, and the first rotating speed is greater than the second rotating speed. The inner cylinder of the washing machine rotates at a larger first rotating speed, so that the clothes to be washed can rotate against the inner wall of the inner cylinder. In the stage of washing clothes, the inner cylinder of the washing machine rotates at a second rotating speed. When the second rotating speed is smaller, the mechanical force on the clothes during washing can be avoided to prevent the woolen clothes from shrinking and deforming due to excessive force.

[0043] It can be understood that different weight of laundry to be washed needs different amount of water to be sprayed, and the parameters of washing are also different. Therefore, the corresponding relationship between the weight of laundry to be washed and the washing parameters can be tested in advance, and after the weight of laundry to be washed is measured, the corresponding relationship obtained in advance can be used to determine the washing parameters of the laundry to be washed. The washing parameters may, for example, include the water inlet time and the rotation speed of the motor required for the water inlet soaking stage of the laundry of difficult water absorption material, and the washing time and the rotation speed of the motor required for the water inlet washing stage of the laundry of difficult water absorption material.

[0044] In some embodiments, the first washing parameter in step S130 further includes at least one of a first rotation stop ratio and a first running time; see Figure 2 The method of the present application is shown in the flowchart of an embodiment of the first rotation stop ratio and the first running time provided in the soaking stage, and specifically includes steps S210 and S220.

[0045] In step S210, when the first washing parameter further includes the first rotation stop ratio, the motor of the washing machine is further controlled to operate according to the first rotation stop ratio in the water inlet soaking stage of the laundry of difficult water absorption material; wherein during the operation of the motor of the washing machine according to the first rotation stop ratio, the motor of the washing machine is operated at the first rotation speed when the motor is operated.

[0046] In step S220, when the first washing parameter further includes the first running time, the water inlet soaking stage of the laundry of difficult water absorption material is ended when the running time of the washing machine in the water inlet soaking stage of the laundry of difficult water absorption material is greater than or equal to the first running time.

[0047] Optionally, the first rotation speed is between 100 r / min and 150 r / min, and preferably the first rotation speed is 100 r / min. The first rotation stop ratio is (100-300):(1-6), and preferably the first rotation stop ratio is 200:4.

[0048] The present application sets a rotation-stop ratio in the stage of soaking clothes, controls the motor of the washing machine to make the inner drum of the washing machine rotate at a first rotation speed with a first rotation-stop ratio interval, so that the wool clothes can run close to the wall, the spray port can uniformly spray on the inner side of the wool clothes close to the wall, and the effective spraying area is increased. When the inner drum rotates at a high speed, the water mist suspended on the surface of the wool fabric can be given a centrifugal force to accelerate the penetration into the internal fibers of the wool. However, the first rotation speed cannot be too large. If the first rotation speed is too large, the inner drum at a high rotation speed for a long time can cause the phenomenon of hitting the barrel to cause damage to the equipment, and when the rotation speed is too large, the moisture in the wool fabric can be thrown out, which is not conducive to the soaking of the clothes. In order to obtain better soaking effect and avoid adverse effects, for example, the first rotation speed can be set to between 100 r / min and 150 r / min, and preferably the first rotation speed is 100 r / min. The rotation-stop ratio is set to make the inner drum rotate intermittently and stop, so that the clothes can be close to the wall or away from the wall. The rotation-stop ratio is set according to the phenomenon of the load (clothes) running in the barrel during the experiment. When the inner drum rotates at a high speed, the clothes close to the wall will be separated from the inner drum wall and fall to the bottom of the inner drum. When the inner drum rotates again, the clothes can run close to the wall again in a different state than before. After multiple close-to-wall or away-from-wall operations, the clothes can be turned over and sprayed, the soaking effect of the spray is more uniform, and the clothes can be prevented from being partially soaked or not soaked. The washing effect of the clothes can be improved. The first rotation-stop ratio can be set to between 100:1 and 300:6, for example, it can be set to 200:4, and a better clothes turning and spraying effect can be obtained.

[0049] In the present application, after the washing program of the washing machine is started, the weight of the clothes to be washed in the barrel is measured to obtain the weight of the clothes to be washed. According to the weight of the clothes to be washed, the time T1 required for soaking the clothes to be washed can be obtained. For example, in the washing machine control program, there is a corresponding relationship between the weight value of the clothes to be washed and the time value required for soaking the clothes. The weight of the clothes to be washed is measured by using the weight detection unit or the weighing sensor of the washing machine to obtain the weight value of the clothes to be washed. According to the corresponding relationship, the time value required for soaking the clothes can be determined, that is, T1 is obtained. In the time T1, the spraying device of the washing machine continuously sprays the clothes to be washed in the washing machine until the spraying time reaches the time T1, and then stops spraying. When the inner drum rotates, the longer the spraying time, the easier the water enters the internal fibers. Continuous spraying can fully soak the wool clothes, further improve the soaking effect of the clothes, and improve the washing effect of the clothes.

[0050] In some embodiments, the second washing parameter further includes at least one of a second rotation-stop ratio and a second running time. See Figure 3The method of the present application is shown in the flowchart of an embodiment of the second rotation-to-stop ratio and the second running time provided in the laundry washing stage, and specifically includes steps S310 and S320.

[0051] At step S310, in the case that the second washing parameter further includes a second rotation-to-stop ratio, the motor of the washing machine is controlled to operate according to the second rotation-to-stop ratio during the water feeding main washing stage of the difficult water-absorbing material clothes; wherein during the operation of the motor of the washing machine according to the second rotation-to-stop ratio, the motor of the washing machine is operated according to the second rotation speed in the case that the motor is operated.

[0052] At step S320, in the case that the second washing parameter further includes a second running time, the water feeding main washing stage of the difficult water-absorbing material clothes is ended in the case that the running time of the washing machine during the water feeding main washing stage of the difficult water-absorbing material clothes is greater than or equal to the second running time.

[0053] Optionally, the second rotation speed is between 35 r / min and 55 r / min, and preferably the second rotation speed is 45 r / min. The second rotation-to-stop ratio is (45-65):(1-3), and preferably the second rotation-to-stop ratio is 60:2.

[0054] In the present application, in the laundry washing stage, the faster the rotation speed of the inner drum, the greater the mechanical force acting on the clothes. In order to better protect the wool material clothes from being deformed and shrunk by excessive mechanical force, the rotation speed of the inner drum in the laundry washing stage is set to a smaller second rotation speed, for example, the second rotation speed can be set to be between 35 r / min and 55 r / min, and preferably the second rotation speed is 45 r / min, which can achieve the above-mentioned effect. In the laundry washing stage, the second rotation-to-stop ratio is set to effectively wash each part of the clothes, improve the washing rate, prevent the clothes from being excessively entangled during the washing process, avoid the deformation of the clothes, and protect the clothes; and the intermittent operation of the motor during the washing process can also protect the motor. For example, the second rotation-to-stop ratio is set to (45-65):(1-3), and preferably the second rotation-to-stop ratio is 60:2. The setting parameter of the second rotation-to-stop ratio is obtained according to the phenomenon existing in the rotation and throwing process of the load (clothes) in the drum of the washing machine, and the test parameters of the difficult water-absorbing material clothes under different conditions.

[0055] In some embodiments, the length of time T2 required for washing the soaked laundry is determined according to the weight of the laundry to be washed. In the soaking stage, the inner drum of the washing machine rotates at a first rotational speed, and the laundry to be washed is rotated while being attached to the inner wall of the inner drum and is soaked by spraying water into the inner drum. In the washing stage, the washing process is timed after the start of washing, and the washing time t2 is recorded; when the washing time t2 reaches the length of time T2 required for washing, the washing is stopped.

[0056] According to the present application, after the washing program of the washing machine is started, the weight of the laundry to be washed in the drum is measured, and the length of time T2 required for washing the soaked laundry is obtained according to the weight of the laundry to be washed. For example, in the control program of the washing machine, a corresponding relationship between the weight of the laundry to be washed and the length of time required for washing the laundry is preset, the weight of the laundry to be washed is measured by using the weight detection unit or the weighing sensor of the washing machine, the weight value of the laundry to be washed is obtained, and the length of time required for washing the laundry is determined according to the corresponding relationship, that is, T2 is obtained. In the length of time T2, the washing machine washes the laundry, and when the length of time of washing reaches the length of time T2, the washing is stopped. The washing process for a sufficient length of time can thoroughly wash the laundry, and the laundry is not deformed, shrunk, or even damaged due to a long washing time.

[0057] As described above, the length of time T1 required for soaking the laundry to be washed and the length of time T2 required for washing the soaked laundry can be obtained according to the weight of the laundry to be washed, and the washing process is controlled accordingly, and the implementation thereof will not be described herein.

[0058] In some embodiments, the spraying device is controlled to be intermittently opened, including: when the running time of the washing machine in the main washing stage of the water inlet of the laundry of the difficult water-absorbing material reaches n·100 seconds, the spraying valve is controlled to be opened for a set length of time and then closed, wherein n is a positive integer.

[0059] Optionally, when the length of time of washing reaches n·100 seconds, the inner drum is washed by spraying, and the length of time of each washing spraying is x seconds, wherein n is a positive integer.

[0060] According to the present application, in the washing stage, the inner drum of the washing machine is washed by spraying water, which can further soak the laundry, and the woolen laundry is prevented from floating on the water during washing, so that the washing effect is improved. The inner drum is washed by spraying at a fixed interval, for example, every 100 seconds, which can achieve the above-mentioned effect. The length of time of each washing spraying is set to x seconds according to the need for soaking the laundry, and x seconds can be any length of time that is less than the length of time T2 required for washing.

[0061] According to the technical scheme of the embodiment, in the stage of soaking clothes, the inner drum of the washing machine rotates at a first rotating speed, so that the clothes to be washed are rotated while adhering to the inner wall of the inner drum, and the inner drum is soaked by spraying water. The clothes of difficult water absorption such as wool are always operated while adhering to the inner wall of the inner drum of the washing machine, the water is directly sprayed to the surface of the clothes adhering to the inner wall of the drum by the spraying valve, so as to quickly and effectively wet the clothes, and the washing effect is improved. In the stage of washing clothes, the inner drum of the washing machine rotates at a second rotating speed, and the inner drum is washed by spraying water. The mechanical force and force acting on the clothes are small, and the clothes are not heated during normal temperature washing, so that the shrinkage of the clothes is effectively reduced, and the user experience is improved. According to the embodiment of the present application, a control device of a washing machine corresponding to a control method of the washing machine is also provided. Referring to Figure 4 The structure diagram of an embodiment of the control device of the washing machine of the present application is shown.

[0062] According to the embodiment of the present application, a control device of a washing machine is provided, the washing machine has a spraying device, the spraying device has a spraying valve, and the spraying valve is used to control the opening and closing of the spraying device, as Figure 4 The structure diagram of an embodiment of the control device of the washing machine of the present application is shown, and the control device of the washing machine can include an acquisition unit 410 and a control unit 420.

[0063] The acquisition unit 410 is configured to acquire the material of the clothes to be washed in the washing machine, and acquire the weight of the clothes to be washed.

[0064] The acquisition unit 410 is further configured to, in the case that the material of the clothes to be washed is a difficult water absorption material, determine the washing parameter of the clothes to be washed according to the weight of the clothes to be washed.

[0065] The control unit 420 is configured to start a preset difficult water absorption material clothes washing program according to the washing parameter of the clothes to be washed. The difficult water absorption material clothes washing program includes a difficult water absorption material clothes soaking stage. Correspondingly, the washing parameter of the clothes to be washed includes a first washing parameter of the difficult water absorption material clothes soaking stage. The first washing parameter includes a first rotating speed.

[0066] The control unit 420 is further configured to, in the difficult water absorption material clothes soaking stage, control the spraying valve to be opened, and control the motor of the washing machine to rotate at the first rotating speed, so that the clothes to be washed adhere to the inner wall of the inner drum of the washing machine and rotate with the inner drum, and are soaked in the process of being sprayed to the inner wall of the inner drum by the spraying device.

[0067] The present application changes the water inlet mode of the clothes made of difficult water-absorbing material such as wool in the traditional mode, and obtains the phenomenon that the clothes can run close to the wall through long-term test observation of the state of different clothes quantity in the washing process by adjusting the rotation speed of the inner drum of the washing machine. In the embodiment, the clothes run close to the wall while being sprayed with water, and the wool clothes always run close to the inner wall of the inner drum of the washing machine in the whole water spraying process. The spraying valve sprays water directly to the surface of the wool clothes running close to the wall in the water spraying process. In the rotation process, the water mist attached to the surface of the wool is accelerated to penetrate into the inside of the wool fabric due to the centrifugal force, so as to achieve the effect of rapid wetting in washing and improve the washing effect.

[0068] The wool clothes run close to the wall in the main washing water inlet process, so that there is no relative movement between the clothes and the clothes and between the clothes and the inner drum. There is no large mechanical force and action in this process, and heating is not needed in the main washing stage, so that normal temperature washing can be realized. In this way, the mechanical force and temperature that cause the wool shrinkage phenomenon can be reduced.

[0069] In some embodiments, the control unit 420 is further configured to the difficult water-absorbing material clothes washing program, and the washing parameter of the clothes to be washed includes the second washing parameter of the difficult water-absorbing material clothes water inlet main washing stage. The second washing parameter includes a second rotation speed. In the difficult water-absorbing material clothes water inlet main washing stage, the motor of the washing machine is controlled to rotate at the second rotation speed, and the spraying device is controlled to be intermittently opened, so that the clothes to be washed are washed at the second rotation speed, and are further wetted in the process of spraying water to the inner wall of the inner drum after the spraying device is intermittently opened. The first rotation speed is greater than the second rotation speed. The acquisition unit 410 determines the washing parameter of the clothes to be washed according to the weight of the clothes to be washed in the case that the material of the clothes to be washed is difficult water-absorbing material, and the washing parameter includes:

[0070] In the case that the material of the clothes to be washed is difficult water-absorbing material, the corresponding relationship between the set weight and the set washing parameter is determined, the set washing parameter corresponding to the set weight same as the weight of the clothes to be washed in the corresponding relationship is determined as the washing parameter of the clothes to be washed.

[0071] In the soaking clothes phase, the inner drum of the washing machine rotates at a first rotating speed, the first rotating speed is greater than the second rotating speed, and the inner drum of the washing machine rotates at the first rotating speed, so that the clothes to be washed can rotate and adhere to the inner wall of the inner drum. In the washing clothes phase, the inner drum of the washing machine rotates at a second rotating speed, and the second rotating speed is smaller, so that the mechanical force on the clothes during washing can be avoided, and the woolen clothes can be prevented from shrinking and deforming due to excessive force.

[0072] It can be understood that different clothes weights require different amounts of sprayed water and washing times. Therefore, the correspondence between the weight and the washing parameter can be tested in advance, and after the weight of the clothes to be washed is measured, the washing parameter of the clothes to be washed can be determined based on the correspondence obtained in advance, in which the set washing parameter corresponding to the set weight same as the weight of the clothes to be washed. The washing parameter may, for example, include the time and rotating speed required for the woolen clothes to soak in water, and the time and rotating speed required for the woolen clothes to wash in water.

[0073] In some embodiments, the first washing parameter further includes at least one of a first rotation-to-stop ratio and a first running time; and the control unit 420 is configured to perform steps S210 and S220 of the method 200. Figure 2

[0074] In step S210, when the first washing parameter further includes the first rotation-to-stop ratio, the motor of the washing machine is controlled to operate according to the first rotation-to-stop ratio during the water-soaking phase of the clothes of the difficult-to-absorb material; wherein during the operation of the motor of the washing machine according to the first rotation-to-stop ratio, the motor of the washing machine is operated according to the first rotating speed.

[0075] In step S220, when the first washing parameter further includes the first running time, the water-soaking phase of the clothes of the difficult-to-absorb material ends when the running time of the washing machine in the water-soaking phase of the clothes of the difficult-to-absorb material is greater than or equal to the first running time.

[0076] Optionally, the first rotating speed is between 100 r / min and 150 r / min, and the first rotation-to-stop ratio is 200:4.

[0077] ​The present application sets a rotation-stop ratio in the stage of soaking clothes, controls the motor of the washing machine to make the inner drum of the washing machine rotate at a first rotation speed with a first rotation-stop ratio interval, so that the wool fabric runs against the wall, the spray port can uniformly spray on the inner side of the wool clothes against the wall, and the effective spraying area is increased. When the inner drum rotates at a high speed, the water mist suspended on the surface of the wool fabric can be given a centrifugal force to accelerate its penetration into the internal fibers of the wool. However, the first rotation speed cannot be too large. If the first rotation speed is too large, the inner drum may be damaged due to the phenomenon of hitting the barrel for a long time at a high speed, and the water in the wool fabric may be thrown out when the rotation speed is too large, which is not conducive to the soaking of the clothes. Therefore, in order to obtain better soaking effect and avoid adverse effects, the first rotation speed can be set to between 100 r / min and 150 r / min. The rotation-stop ratio is set to make the inner drum rotate intermittently and stop, so that the clothes can be attached to or separated from the wall. The rotation-stop ratio is set according to the phenomenon of the load (clothes) running in the barrel during the experiment. When the inner drum rotates at a high speed, the clothes attached to the wall will fall off the inner drum wall and fall to the bottom of the inner drum. When the inner drum rotates again, the clothes can run against the wall again. After multiple attachment or separation, the clothes can be turned over and sprayed, the soaking effect of the spray is more uniform, and the clothes can be prevented from being partially soaked or not soaked. The washing effect of the clothes can be improved. When the first rotation-stop ratio is set to 200:4, better effect of turning over and spraying of the clothes can be obtained.

[0078] In the present application, after the washing program of the washing machine is started, the weight of the clothes to be washed in the barrel is measured to obtain the weight of the clothes to be washed. According to the weight of the clothes to be washed, the time T1 required for soaking the clothes to be washed can be obtained. For example, in the control program of the washing machine, a corresponding relationship between the weight of the clothes to be washed and the time required for soaking the clothes is preset. The weight of the clothes to be washed is measured by using the weight detection unit or the weighing sensor of the washing machine to obtain the weight value of the clothes to be washed. According to the corresponding relationship, the time value required for soaking the clothes can be determined, that is, T1 is obtained. In the time T1, the spraying device of the washing machine continuously sprays the clothes to be washed in the washing machine until the spraying time reaches the time T1, and then the spraying is stopped. When the inner drum rotates, the longer the spraying time is, the easier the water enters the internal fibers. Continuous spraying can fully soak the wool clothes, further improve the soaking effect of the clothes, and improve the washing effect of the clothes.

[0079] In some embodiments, the second washing parameter further includes at least one of a second rotation-stop ratio and a second running time. The control unit 420 is configured to perform steps S310 to S320 as Figure 3

[0080] ​At step S310, in the case that the second washing parameter further comprises a second rotation-stop ratio, the motor of the washing machine is controlled to operate according to the second rotation-stop ratio during the water-impregnated main washing stage of the difficult water-absorbing material clothes; wherein, during the operation of the motor of the washing machine according to the second rotation-stop ratio, the motor of the washing machine is operated at the second rotation speed when the motor is operated.

[0081] At step S320, in the case that the second washing parameter further comprises a second operation time, the water-impregnated main washing stage of the difficult water-absorbing material clothes is ended in the case that the operation time of the washing machine during the water-impregnated main washing stage is greater than or equal to the second operation time.

[0082] Optionally, the second rotation speed is between 35 r / min and 55 r / min, and preferably the second rotation speed is 45 r / min. The second rotation-stop ratio is (45-65):(1-3), and preferably the second rotation-stop ratio is 60:2.

[0083] In the present application, the faster the rotation speed of the inner drum during the washing stage, the greater the mechanical force acting on the clothes, so that the clothes made of wool material are better protected from being deformed and shrunk due to excessive mechanical force. In order to achieve the above-mentioned effect, the rotation speed of the inner drum during the washing stage is set to a second rotation speed, for example, the second rotation speed can be set to be between 35 r / min and 55 r / min. By setting the second rotation-stop ratio during the washing stage, each part of the clothes can be effectively washed, the washing rate is improved, and the clothes are prevented from being excessively entangled during the washing process, so that the clothes are protected from being deformed, and the motor is also protected during the intermittent operation of the washing process.

[0084]

[0085] For example, the second rotation-stop ratio is set to 60:2, and the setting parameter of the second rotation-stop ratio 0 is obtained according to the phenomenon that the load (clothes) in the drum of the washing machine is thrown during rotation, and the test parameter of the difficult water-absorbing material clothes under different conditions.

[0086] In some embodiments, the length of time T2 required for washing the impregnated clothes is determined according to the weight of the clothes to be washed. During the impregnation stage of the clothes, the inner drum of the washing machine rotates at a first rotation speed, so that the clothes to be washed are impregnated by being sprayed with water in the form of spraying.

[0087] During the washing stage, the washing process is timed after the start of washing, and the washing time t2 is recorded; and the washing is stopped when the washing time t2 reaches the length of time T2 required for washing.

[0088] ​​

[0089] The present application measures the weight of the laundry in the drum after the washing program is started, and obtains the weight of the laundry. According to the weight of the laundry, the time T2 required for washing the soaked laundry can be obtained. For example, the washing machine control program has a preset corresponding relationship between the weight of the laundry and the time required for washing the laundry. The weight of the laundry is measured by the weight detection unit or the weight sensor of the washing machine, and the weight value of the laundry is obtained. According to the corresponding relationship, the time required for washing the laundry can be determined, i.e., T2 is obtained. During the time T2, the washing machine washes the laundry until the washing time reaches the time T2, and then stops washing. The washing process for a sufficient time ensures that the laundry is thoroughly cleaned, and the laundry is not deformed, shrunk, or even damaged due to excessive washing time.

[0090]

[0091]

[0092]

[0093] 5As described above, according to the weight of the laundry, the time T1 required for soaking the laundry and the time T2 required for washing the soaked laundry can be obtained at the same time, and the washing process is controlled accordingly. The implementation of this will not be described again.

[0094] In some embodiments, the control unit 420 controls the intermittent opening of the spraying device, including: controlling the control unit 420 to open the spraying valve for a set time and then close it every 0 to n*100 seconds during the operation time of the washing machine in the main washing stage of the water-absorbing material.

[0095]

[0096]

[0097] Optionally, when the washing time reaches n*100 seconds, the inner drum is sprayed, and the spraying time is x seconds each time, where n is a positive integer.

[0098] In the present application, the inner drum of the washing machine is sprayed with water during the washing process, which can further soak the laundry. Woolen clothes may float on the water during washing, which can reduce the cleaning effect. The inner drum is sprayed at fixed intervals, for example, every 100 seconds, which can achieve the above-mentioned effect. The spraying time is x seconds each time, which can be any time less than the time T2 required for washing.

[0099] ​​​​​The technical scheme of the embodiment is adopted, in the stage of soaking clothes, the inner drum of the washing machine rotates at a first rotating speed, the clothes to be washed are rotated by adhering to the inner wall of the inner drum, and the inner drum is soaked and sprayed in a spraying water inlet mode, the clothes of wool and other difficult water-absorbing materials are always operated by adhering to the inner wall of the inner drum in the spraying water inlet mode, the spraying valve sprays water directly to the surface of the clothes in the barrel to achieve the purpose of quickly and effectively wetting the clothes, so as to improve the washing effect. In the stage of washing clothes, the inner drum of the washing machine rotates at a second rotating speed, and the inner drum is washed and sprayed in a spraying water inlet mode, the mechanical force and force acting on the clothes are small, and the clothes do not need to be heated in normal temperature washing, so that the shrinkage of the clothes is effectively reduced and the user experience is improved.

[0100] Figure 5 It is a schematic diagram of the overall structure of the washing machine of the present application, Figure 6 It is a sectional view of the washing machine of the present application. As Figure 5 shown, the washing machine comprises a detergent box 1, a display screen 2, a door body 3, a drainage pump 4, and a washing machine shell 5. As Figure 6 shown, the inside of the washing machine comprises a spraying head 6 and an inner drum 8. When the washing machine sprays water, the water flow is sprayed out of the spraying head 6, the spraying water mist 7 falls on the clothes in the inner drum 8 through the spraying path, and the clothes run by adhering to the wall in this process. The water inlet valve sprays water on the surface of the clothes, and the surface of the clothes is subjected to centrifugal force under the condition of high-speed rotation, so as to accelerate the surface of the clothes to quickly absorb water and achieve the effect of being soaked. The spraying water of the conventional washing machine is mainly used for spraying and cleaning the foam on the glass bowl during the washing process. In the present scheme, in addition to being able to spray and clean the glass bowl, the spraying head 6 has a set angle, so that the water mist sprayed out of the spraying head 6 can effectively spray the inner drum of the washing machine. Different from the spraying mode of the conventional spraying head to the glass bowl in the washing machine, the angle of the spraying head of the present scheme is to spray the inner drum of the washing machine, so that the spraying head 6 can better spray the clothes in the inner drum of the washing machine. The specific value of the angle is not limited. The spraying head 6 optimizes and improves the spraying structure device, can increase the effective area of the spraying head to the inner drum, and achieves the effect of quickly wetting the clothes.

[0101] Figure 7 It is a flowchart of an embodiment of a method for implementing the washing control logic of a washing machine. As Figure 7As shown, the washing control logic is mainly divided into two stages, one is the main washing water inlet stage, and the other is the washing stage. The flow is as follows: when the user selects the wool washing program of the washing machine, the water inlet mode under this program is default to spray water inlet. After starting the washing program S701, the washing machine starts to weigh the laundry in the inner drum S702, and after the weighing is completed, the main washing water inlet is started S703, at this time the spray valve is opened, the spray valve starts timing t1, the inner drum starts rotating at speed A, the rotation stop ratio a:b, and the spray valve is always opened in this rotating process. S704 When the spray valve opening time is greater than T1, the spray valve is closed. Enter the washing stage S705. In this stage, the washing S706, the inner drum rotates at speed B, the rotation stop ratio c:d, S707 the synchronous timer starts timing, records the washing time t2. When t2 is a multiple of 100 seconds, the spray valve is opened for X seconds and then closed, otherwise it runs according to S706. In this washing process, when t2 is greater than T2, the washing stage is ended and the next stage is entered. t1++ in step S704 represents the timer timing of the spray valve opening. If it is judged that the spray valve opening time t1 has not reached the predetermined spray water inlet time T1, the timer continues to calculate the time, and if the predetermined time T1 is reached, the spray valve stops spraying and jumps out of step S704 to enter the next step. t2++ in step S708 represents the timer timing of the washing stage. If it is judged that the washing opening time t2 has not reached the predetermined washing time T2, the timer continues to calculate the time, and if the predetermined time T2 is reached, the washing is stopped and the next step is entered.

[0102] For the above implementation case, the speed A is the best speed between 100r / min-150r / min, the rotation stop ratio a:b is optimal between 200:4; the time T1 is the best between 10min-15min. The speed B is selected between 35r / min-55r / min, and the rotation stop ratio c:d is optimal at 60:2. The time T2 is the optimal washing time between 20min-35min.

[0103] By adopting the technical scheme of the embodiment, in the stage of soaking the laundry, the inner drum of the washing machine rotates at a first speed, so that the laundry to be washed is rotated while adhering to the inner wall of the inner drum, and the inner drum is soaked by spraying water in a spraying water inlet mode. The spraying water inlet mode of adhering to the inner wall enables the woolen clothes to always adhere to the inner wall of the inner drum, and the spray valve sprays water directly to the surface of the woolen clothes adhering to the inner wall of the drum to quickly and effectively wet the clothes, thereby improving the washing effect. In the stage of washing the laundry, the inner drum of the washing machine rotates at a second speed, and the inner drum is washed by spraying water in a spraying water inlet mode. The mechanical force and the force acting on the laundry are small, and the normal temperature washing does not need heating, which can effectively reduce the shrinkage of the laundry and improve the user experience.
