The entire contents of these four Chinese patent applications are incorporated herein by reference. Technical Field

[0001] This invention relates to the field of clothing processing technology, and specifically provides a control method for clothing processing equipment and clothing processing equipment. Background Technology

[0002] Existing clothing handling equipment mainly includes washing machines, dryers, or washer-dryer combos. Washing machines are devices that can wash clothes; some washing machines also include a fresh air system. When operating in fresh air mode, this system supplies fresh air into the drum to prevent odors from developing on the clothes inside. Dryers are devices that can dry clothes, while washer-dryer combos are devices that can both wash and dry clothes.

[0003] Whether in fresh air mode or drying mode, the clothes handling drum needs to rotate and supply fresh air or hot air into it. However, as the clothes handling drum rotates, some clothes can easily get tangled together, affecting the fresh air or drying effect.

[0004] Therefore, a new technical solution is needed in this field to solve the above problems. Summary of the Invention

[0005] The present invention aims to solve the above-mentioned technical problem, namely, to solve the problem that clothes in the drum of existing clothing handling equipment tend to get tangled when the fresh air mode or drying mode is executed.

[0006] In a first aspect, the present invention provides a control method for a garment processing device, the garment processing device including a housing and a garment processing drum rotatably disposed within the housing, the control method including: acquiring the type of garment in the garment processing drum; acquiring a rotation mode corresponding to the type of garment; and causing the garment processing drum to operate according to the rotation mode.

[0007] In the preferred embodiment of the control method for the above-mentioned clothing processing equipment, the rotation mode includes an anti-tangling rotation mode and a standard rotation mode. The step of "obtaining the rotation mode corresponding to the type of clothing" specifically includes: if the type of clothing is prone to tangling, then the corresponding rotation mode is the anti-tangling rotation mode.

[0008] In the preferred embodiment of the control method for the above-mentioned clothing processing equipment, the anti-tangling rotation mode has multiple speed stages, and the clothing processing drum rotates at different speeds in different speed stages.

[0009] In a preferred embodiment of the control method for the aforementioned garment processing equipment, the number of anti-tangling rotation modes is at least two, and the minimum rotation speed in the multiple rotation speed stages of different anti-tangling rotation modes is different. When the type of garment is prone to tangling, the control method further includes: obtaining the weight of the garment in the garment processing drum; obtaining the anti-tangling rotation mode corresponding to the weight of the garment; wherein the magnitude of the minimum rotation speed in the multiple rotation speed stages of the anti-tangling rotation mode is positively correlated with the weight of the garment.

[0010] In the preferred embodiment of the control method for the above-mentioned clothing processing equipment, the plurality of rotational speed stages of the anti-tangling rotation mode include a rotational speed stage in which the rotational speed reaches the centrifugal speed.

[0011] In the preferred embodiment of the control method for the above-mentioned clothing processing equipment, the rotation speed of the multiple rotation speed stages of the anti-tangling rotation mode increases sequentially.

[0012] In the preferred embodiment of the control method for the above-mentioned garment processing equipment, the standard rotation mode has multiple rotation speed stages, and the garment processing drum rotates at different speeds in different rotation speed stages. The lowest speed in the multiple rotation speed stages of the anti-tangling rotation mode is greater than the lowest speed in the multiple rotation speed stages of the standard rotation mode.

[0013] In a preferred embodiment of the control method for the aforementioned garment processing equipment, the plurality of rotational speed stages of the standard rotational mode include a speed stage in which the rotational speed reaches the centrifugal speed; and / or the rotational speeds of the plurality of rotational speed stages of the standard rotational mode increase sequentially.

[0014] In the preferred embodiment of the control method for the above-mentioned clothing processing equipment, the step of "obtaining the rotation mode corresponding to the type of clothing" further includes: if the type of clothing is not easily tangled, then the corresponding rotation mode is the standard rotation mode.

[0015] In a second aspect, the present invention also provides a garment processing apparatus, including a controller configured to perform the control method described above.

[0016] When the above technical solution is adopted, the clothing processing drum of the clothing processing device of the present invention has multiple different rotation modes. When executing the fresh air mode or the drying mode, the appropriate rotation mode can be selected according to the type of clothing in the clothing processing drum. In different rotation modes, the clothing processing drum has different rotation methods and speeds. By making the rotation mode of the clothing processing drum compatible with the type of clothing in the clothing processing drum, it is beneficial to prevent the clothing from getting tangled and to ensure that the clothing can fully contact the fresh air or hot air in the drum, thereby helping to ensure the fresh air effect or drying effect.

[0017] Furthermore, the anti-tangling rotation mode of the present invention has multiple different rotation speed stages. In different rotation speed stages, the clothes processing drum rotates at different speeds. With this setting, the clothes can continuously change position inside the clothes processing drum, so that the clothes can have more full contact with the fresh air or hot air inside the drum, thereby making it more conducive to ensuring the fresh air effect or drying effect.

[0018] Furthermore, the garment processing device of the present invention has multiple different anti-tangling rotation modes in its garment processing drum. After determining that the type of garment in the garment processing drum is prone to tangling, a more suitable anti-tangling rotation mode is selected based on the weight of the garment in the garment processing drum. This setting is more conducive to preventing garments from tangling.

[0019] Furthermore, when the clothes processing drum rotates at a centrifugal speed, the clothes inside the drum will stick to the inner surface of the drum, creating a cavity in the middle. The fresh air entering the drum is then discharged through the holes in the drum wall, which helps the incoming fresh air penetrate the clothes and thus better prevents the clothes in the drum from developing odors, ensuring the fresh air effect.

[0020] Furthermore, the clothing processing device provided by the present invention, based on the above technical solution, includes the above control method and thus possesses the technical effects of the above control method. Compared with the clothing processing device before the improvement, the clothing processing device of the present invention can better prevent clothing from tangling when executing the fresh air mode or the drying mode.

[0021] In a third aspect, the present invention provides a control method for a garment processing device, the garment processing device including a housing and a garment processing drum rotatably disposed within the housing, the control method including: acquiring the weight of garments in the garment processing drum; acquiring a rotation mode corresponding to the weight of the garments; and causing the garment processing drum to operate according to the rotation mode; wherein at least one of the rotation modes has multiple different rotation speed stages, and the garment processing drum rotates at different rotation speed stages.

[0022] In the preferred embodiment of the control method for the above-mentioned clothing processing equipment, each rotation mode has multiple rotation speed stages, at least one of the multiple rotation speed stages has a rotation speed that reaches the centrifugal speed, and the first rotation speed stage among the multiple rotation speed stages is the initial rotation speed stage. The rotation speed of the initial rotation speed stage is different in different rotation modes, and the rotation speed of the initial rotation speed stage is less than the centrifugal speed.

[0023] In the preferred embodiment of the control method for the above-mentioned clothing processing equipment, the rotation speed in the initial rotation speed stage under different rotation modes is positively related to the weight of the clothing.

[0024] In the preferred embodiment of the control method for the above-mentioned clothing processing equipment, the rotational speeds of the multiple rotational speed stages increase sequentially.

[0025] In the preferred embodiment of the control method for the above-mentioned clothing processing equipment, different rotation modes have different numbers of rotation speed stages.

[0026] In the preferred embodiment of the control method for the above-mentioned clothing processing equipment, the number of rotation speed stages is inversely related to the weight of the clothing.

[0027] In the preferred embodiment of the control method for the above-mentioned clothing processing equipment, the duration of the same rotational speed phase varies in different rotational modes.

[0028] In the preferred embodiment of the control method for the above-mentioned clothing processing equipment, the duration of different rotation speed stages in the same rotation mode is different.

[0029] In a preferred embodiment of the control method for the aforementioned garment processing equipment, the rotation mode includes a first rotation mode and a second rotation mode. The garment processing drum rotates at a centrifugal speed during the rotational speed phase of the first rotation mode. The second rotation mode has multiple rotational speed phases, at least one of which reaches the centrifugal speed. The step of "obtaining the rotation mode corresponding to the weight of the garment" specifically includes: if the weight of the garment is less than a preset value, the rotation mode corresponding to the weight of the garment is the first rotation mode; if the weight of the garment is not less than the preset value, the rotation mode corresponding to the weight of the garment is the second rotation mode.

[0030] In the preferred embodiment of the control method for the above-mentioned clothing processing equipment, the number of the second rotation modes is at least two, the first rotation mode of the plurality of rotation speed stages is the initial rotation speed stage, the rotation speed of the initial rotation speed stage is different in different second rotation modes, and the rotation speed of the initial rotation speed stage is less than the centrifugal rotation speed.

[0031] In the preferred embodiment of the control method for the above-mentioned garment processing equipment, the rotational speed of the initial rotational stage in different second rotational modes is positively related to the weight of the garment.

[0032] In the preferred embodiment of the control method for the above-mentioned clothing processing equipment, the rotational speeds of the multiple rotational speed stages increase sequentially.

[0033] In the preferred embodiment of the control method for the above-mentioned clothing processing equipment, different second rotation modes have different numbers of rotation speed stages.

[0034] In the preferred embodiment of the control method for the above-mentioned clothing processing equipment, the number of rotation speed stages is inversely related to the weight of the clothing.

[0035] In the preferred embodiment of the control method for the above-mentioned clothing processing equipment, the duration of the same rotational speed phase in different second rotational modes is different.

[0036] In the preferred embodiment of the control method for the above-mentioned clothing processing equipment, the duration of the different rotational speed stages in the second rotational mode is different.

[0037] In a fourth aspect, the present invention also provides a garment processing apparatus, including a controller configured to perform the control method described above.

[0038] With the above technical solution adopted, the clothing processing device of the present invention has multiple different rotation modes. By adopting a rotation mode adapted to the weight of the clothes in the clothing processing drum, the rotation mode has multiple different speed stages. By rotating the clothing processing drum at different speeds, it is beneficial to quickly change the position of the clothes in the clothing processing drum. When executing the fresh air mode, by quickly changing the position of the clothes in the clothing processing drum, the clothes can have more full contact with the blown fresh air, which is more conducive to preventing the clothes from producing odors and improving the fresh air exchange effect. When executing the drying mode, by quickly changing the position of the clothes in the clothing processing drum, the clothes can have more full contact with the blown hot air, which is more conducive to drying the clothes and improving the drying effect of the clothes.

[0039] Furthermore, by having each rotation mode have multiple rotational speed stages, and each stage reaching centrifugal speed, when the garment processing drum rotates at centrifugal speed, the garments only adhere to the inner drum wall, creating a cavity in the middle of the garment processing drum. This facilitates the penetration of incoming fresh air into the garments, thus better preventing odors from developing on the clothes. In addition, matching the initial rotational speed stage of each rotation mode with the weight of the garments in the garment processing drum is more conducive to changing the position of the garments in the drum and also helps to reduce wear and tear on the garments.

[0040] Furthermore, by gradually increasing the rotational speed in multiple rotational stages, this invention not only changes the position of the clothes in the clothes processing drum but also helps to ensure that the clothes in the clothes processing drum are evenly distributed.

[0041] Furthermore, by matching the number of rotational speed stages in each rotational mode with the weight of the clothes in the clothes processing drum, the present invention facilitates the rapid repositioning of the clothes in the clothes processing drum.

[0042] In a fifth aspect, the present invention provides a control method for a garment processing device, the garment processing device including a housing and a garment processing drum rotatably disposed within the housing, the control method including: acquiring the material of the garments in the garment processing drum; acquiring a rotation mode corresponding to the material of the garments; and causing the garment processing drum to operate according to the rotation mode.

[0043] In the preferred embodiment of the control method for the above-mentioned clothing processing equipment, the rotation mode includes a standard rotation mode and a low-wear rotation mode. The step of "obtaining the rotation mode corresponding to the material of the clothing" specifically includes: if the material of the clothing is a wear-prone material, the corresponding rotation mode is the low-wear rotation mode; if the material of the clothing is not a wear-prone material, the corresponding rotation mode is the standard rotation mode.

[0044] In a preferred embodiment of the control method for the aforementioned garment processing equipment, the number of low-wear rotation modes is at least two. When the garment is made of a wear-prone material, the control method further includes: obtaining the weight of the garment in the garment processing drum; and obtaining the low-wear rotation mode corresponding to the weight of the garment.

[0045] In the preferred embodiment of the control method for the above-mentioned clothing processing equipment, the low-wear rotation mode has a rotation speed stage where the rotation speed reaches the centrifugal speed.

[0046] In the preferred embodiment of the control method for the aforementioned garment processing equipment, the low-wear rotation mode includes a first low-wear rotation mode and a second low-wear rotation mode. When executing the first low-wear rotation mode, the rotation speed of the garment processing drum is directly accelerated to the centrifugal speed. When executing the second low-wear rotation mode, the rotation speed of the garment processing drum is first accelerated to a set speed, and the garment processing drum runs at the set speed for a set time before accelerating to the centrifugal speed. The step of "obtaining the low-wear rotation mode corresponding to the weight of the garment" specifically includes: if the weight of the garment is less than a preset value, the corresponding low-wear rotation mode is the first low-wear rotation mode; if the weight of the garment is not less than the preset value, the corresponding low-wear rotation mode is the second low-wear rotation mode.

[0047] In the preferred embodiment of the control method for the above-mentioned clothing processing equipment, the set rotation speed corresponds to the weight of the clothing.

[0048] In a preferred embodiment of the control method for the above-mentioned clothing processing equipment, the set time corresponds to the weight of the clothing.

[0049] In the preferred embodiment of the control method for the above-mentioned clothing processing equipment, the standard rotation mode has multiple speed stages, and the clothing processing drum rotates at different speeds in different speed stages.

[0050] In a preferred embodiment of the control method for the aforementioned garment processing equipment, the plurality of rotational speed stages include a speed stage in which the rotational speed reaches the centrifugal speed; and / or the rotational speeds of the plurality of rotational speed stages increase sequentially.

[0051] In a sixth aspect, the present invention also provides a garment processing apparatus, including a controller configured to perform the control method described above.

[0052] When the above technical solution is adopted, the clothing processing drum of the clothing processing device of the present invention has multiple different rotation modes. When the fresh air mode or the drying mode is executed, the appropriate rotation mode can be selected according to the material of the clothes in the clothing processing drum. In different rotation modes, the clothing processing drum has different rotation methods and speeds. By making the rotation mode of the clothing processing drum compatible with the material of the clothes in the clothing processing drum, it is beneficial to reduce the wear and tear on the clothes and avoid damage to the clothes.

[0053] Furthermore, when the clothes in the clothes processing drum are made of easily abrasive materials, operating the clothes processing drum in a low-wear rotation mode can effectively reduce the wear and tear on the clothes and prevent damage. When the clothes in the clothes processing drum are not made of easily abrasive materials, operating the clothes processing drum in a standard rotation mode is more conducive to ensuring the fresh air effect or drying effect.

[0054] Furthermore, the garment processing drum of the garment processing device of the present invention has multiple different low-wear rotation modes. After determining that the material of the garment in the garment processing drum is an easily worn material, a more suitable low-wear rotation mode is selected based on the weight of the garment in the garment processing drum. This setting is more conducive to reducing the wear and tear on the garment and also more conducive to ensuring the fresh air effect or drying effect.

[0055] Furthermore, when the garment processing drum rotates at a centrifugal speed, the clothes inside the drum will adhere to the inner surface of the drum and rotate synchronously with it, protecting the clothes and reducing wear. In addition, a cavity is formed in the middle of the drum, and the fresh air entering the drum is discharged through the through holes on the drum wall, which helps the incoming fresh air penetrate the clothes and thus helps prevent the clothes in the drum from developing odors.

[0056] Furthermore, the clothing processing device provided by the present invention, based on the above technical solution, includes the above control method and thus possesses the technical effects of the above control method. Compared with the clothing processing device before the improvement, the clothing processing device of the present invention causes less wear and tear on clothing when executing the fresh air mode or the drying mode.

[0057] In a seventh aspect, the present invention provides a control method for a garment processing device, the garment processing device including a housing, an outer cylinder, an inner cylinder rotatably disposed in the outer cylinder, and a fresh air device communicating with the inner cylinder, the fresh air device including a fresh air duct communicating with the inner cylinder and a fan communicating with the fresh air duct, the control method including: acquiring information about the garments in the inner cylinder; acquiring a preset wind speed corresponding to the information about the garments; and causing the fan to operate according to the preset wind speed.

[0058] In the preferred embodiment of the control method for the above-mentioned clothing processing equipment, the step of "obtaining information about the clothing in the inner drum" specifically includes: "obtaining the material of the clothing in the inner drum"; the step of "obtaining a preset wind speed corresponding to the information of the clothing" specifically includes: obtaining a preset wind speed corresponding to the material of the clothing, wherein the magnitude of the preset wind speed is inversely related to the breathability of the material of the clothing.

[0059] In the preferred embodiment of the control method for the above-mentioned clothing processing equipment, the step of "obtaining information about the clothing in the inner drum" specifically includes: obtaining the weight of the clothing in the inner drum; the step of "obtaining a preset wind speed corresponding to the information of the clothing" specifically includes: obtaining a preset wind speed corresponding to the weight of the clothing, wherein the preset wind speed is positively correlated with the weight of the clothing.

[0060] In a preferred embodiment of the control method for the above-mentioned clothing processing equipment, the control method further includes: rotating the inner drum.

[0061] In the preferred embodiment of the control method for the above-mentioned clothing processing equipment, the step of "making the inner drum rotate" specifically includes: making the inner drum rotate intermittently.

[0062] In the preferred embodiment of the control method for the above-mentioned clothing processing equipment, the rotation-to-stop ratio of the inner drum is positively correlated with the weight of the clothing in the inner drum.

[0063] In the preferred embodiment of the control method for the above-mentioned clothing processing equipment, the step of "making the inner drum rotate" specifically includes: making the inner drum run alternately at multiple different speeds.

[0064] In the preferred embodiment of the control method for the above-mentioned clothing processing equipment, the step of "making the inner drum rotate" specifically includes: making the inner drum rotate clockwise and counterclockwise alternately.

[0065] In a preferred embodiment of the control method for the aforementioned clothing processing equipment, after performing the step of "making the fan run at the preset wind speed", the control method further includes: acquiring the humidity in the inner drum; and selectively reducing the wind speed of the fan based on the humidity in the inner drum.

[0066] In an eighth aspect, the present invention also provides a garment processing apparatus, including a controller configured to perform the control method described above.

[0067] When the above technical solution is adopted, the clothing processing equipment of the present invention needs to start the fresh air device. It is necessary to first determine the fan speed according to the information of the clothes in the inner drum. The fan speed is different for different clothes. By matching the fan speed with the information of the clothes, the fresh air device can provide a more suitable air volume to the inner drum, which helps to avoid the situation where the clothes in the inner drum produce odors due to the fan speed being too low, thus ensuring the fresh air effect of the fresh air device. It also helps to avoid the situation where the fan speed is too high, thus avoiding the situation where energy is wasted, thereby making it more energy-efficient.

[0068] Furthermore, the clothing processing device of the present invention can also rotate the inner drum during the execution of the fresh air mode. By rotating the inner drum, the position of the clothes in the inner drum can be changed as the inner drum rotates, so that the moisture of the clothes can be better released and carried away by the fresh air, which can further improve the fresh air effect and is more conducive to avoiding the generation of odors in the clothes.

[0069] Furthermore, when the inner drum of the garment processing device of the present invention needs to be rotated, the rotation speed of the inner drum corresponds to the weight of the garment in the inner drum. By matching the rotation speed of the inner drum with the weight of the garment in the inner drum, it is beneficial to make the garment in the inner drum tumble smoothly with the inner drum.

[0070] Furthermore, in the garment processing device of the present invention, when the inner drum needs to be rotated, the rotation speed of the inner drum is not fixed, but constantly changing. By constantly changing the rotation speed of the inner drum, it is more beneficial to change the position of the garment in the inner drum, so that the garment tumbles continuously, thereby improving the fresh air effect.

[0071] Furthermore, when the inner drum needs to be rotated, the clothing handling device of the present invention can change the position of the clothes in the inner drum by alternating between forward and reverse rotation, so as to make the clothes tumble continuously and improve the fresh air effect.

[0081] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the invention and are not intended to limit the scope of protection of the invention. For example, although the embodiments described below are in conjunction with a washing machine, the technical solutions of the present invention are equally applicable to other types of clothing handling equipment, such as dryers or washer-dryer combos.

[0082] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that although the steps of the control method of the present invention are described in a specific order in this application, this order is not restrictive, and those skilled in the art can perform the steps in different orders without departing from the basic principles of the present invention.

[0083] It should be noted that in the description of this invention, terms such as "inner," "outer," "upper," "lower," "top," and "bottom," which indicate direction or positional relationships, are based on the direction or positional relationships shown in the accompanying drawings. These are used merely for ease of description and do not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0084] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "set," "connect," and "install" should be interpreted broadly, for example, referring to a fixed connection, a detachable connection, or an integral connection. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0085] Specifically, the present invention provides a washing machine, as shown in FIG1. ​​The washing machine of the present invention includes a housing 1, an outer drum (not shown in the figure), an inner drum 2, and a drive device (not shown in the figure). The outer drum is fixedly installed inside the housing 1 and is mainly used to contain washing water. The inner drum 2 is rotatably disposed in the outer drum and is mainly used to contain clothes to be washed. The inner drum 2 has multiple through holes on its drum wall, through which washing water in the outer drum can enter the inner drum 2. The drive device is generally installed at the rear end of the outer drum and is drivenly connected to the inner drum 2. The drive device is used to drive the inner drum 2 to rotate.

[0086] It should be noted that if the clothing handling equipment is a dryer, the dryer may not have an outer drum, but only a drying drum inside the dryer. The drying drum is used to hold clothes. The dryer has a drying device that is connected to the drying drum. The drying device can deliver hot air into the drying drum to dry the clothes in the drying drum. Both the inner drum of a washing machine and the drying drum of a dryer can be referred to as clothing handling drums.

[0087] Furthermore, it should be noted that if the garment handling equipment is a washer-dryer combo, it also has a drying unit, and in addition, a fresh air system can be installed. This means that a washer-dryer combo can simultaneously offer washing, drying, and fresh air modes. After completing the washing cycle, if the user does not select the drying mode, the fresh air mode can then be activated.

[0088] Preferably, the washing machine of the present invention also has a fresh air function. Specifically, as shown in FIG1, the washing machine of the present invention further includes a fresh air device, which is connected to the inner drum 2. The fresh air device can deliver fresh air to the inner drum 2 to prevent the clothes in the inner drum 2 from growing bacteria and producing odors.

[0089] For example, a fresh air inlet is provided on the casing 1 of the washing machine, and a fresh air outlet is provided on the door seal of the washing machine. The fresh air outlet is positioned facing the inner drum 2. The fresh air device includes a fresh air duct 3 and a fan 4. The fan 4 is installed at the fresh air inlet. One end of the fresh air duct 3 is connected to the fresh air outlet on the door seal, and the other end of the fresh air duct 3 is connected to the exhaust port of the fan 4. When the fresh air mode is executed, the fan 4 is turned on. The fan 4 can draw air from outside the casing 1 into the fresh air duct 3 and allow the drawn air to enter the inner drum 2 along the fresh air duct 3 to ventilate and deodorize the inner drum 2 and the clothes inside. In addition, for washing machines with sterilization functions, it can quickly sterilize and deodorize the inside of the drum and the clothes at the same time. For clothes that are not dried in time after washing, the rotation ventilation can both deodorize and prevent wrinkles.

[0090] It should be noted that, in practical applications, those skilled in the art can also install the fan 4 inside the fresh air duct 3. In this case, one end of the fresh air duct 3 is connected to the fresh air outlet on the window gasket, and the other end of the fresh air duct 3 is connected to the fresh air inlet on the housing 1, etc. Such flexible adjustments and changes do not deviate from the principles and scope of the present invention and should all be limited to the protection scope of the present invention.

[0091] Furthermore, it should be noted that the pressure relief method for the inner drum can be achieved by directly connecting the outer drum to the outside of the housing via a pipe, or by connecting the outer drum to the detergent dispenser of the garment processing equipment via a pipe, etc. Such flexible adjustments and changes do not deviate from the principles and scope of this invention and should all be limited to the protection scope of this invention.

[0092] Example 1

[0093] The present invention also provides a control method for a washing machine. As shown in Figure 2, when executing the fresh air mode, the control method of the present invention includes the following steps: S100: obtaining the type of clothes in the inner drum; S200: obtaining the rotation mode corresponding to the type of clothes; S300: causing the inner drum to operate according to the rotation mode.

[0094] In other words, the inner drum of the washing machine of the present invention has multiple different rotation modes. When the fresh air mode is executed, the appropriate rotation mode can be selected according to the type of clothes in the inner drum. In different rotation modes, the inner drum has different rotation methods and speeds. By adapting the rotation mode of the inner drum to the type of clothes in the inner drum, it is beneficial to prevent clothes from getting tangled, and to ensure that the clothes can fully contact the fresh air, thus avoiding the generation of odors in the clothes in the inner drum.

[0095] It should be noted that the above control methods are also applicable to dryers and washer-dryer combos. Specifically, when executing the drying mode, by adopting a rotation mode that is compatible with the type of clothes in the drying drum, it is beneficial to prevent clothes from getting tangled and to ensure that the clothes can fully contact the hot air, thus guaranteeing the drying effect.

[0096] Furthermore, it should be noted that for washing machines with a fresh air function, a button to activate the fresh air function can be set on the control panel. When the user selects the fresh air function, the washing machine will automatically execute the fresh air mode after completing the washing program. If the user does not select the fresh air function, the washing machine will not execute the fresh air mode after completing the washing program. Alternatively, the washing machine can be set to automatically determine whether to execute the fresh air mode. One or more preset conditions for activating the fresh air function can be stored in the controller of the washing machine. When the preset conditions are met, the washing machine will automatically execute the fresh air mode after completing the washing program, etc. Such flexible adjustments and changes do not deviate from the principles and scope of this invention and should be limited to the protection scope of this invention.

[0097] Furthermore, it should be noted that, in practical applications, those skilled in the art can divide multiple different rotation modes into two categories: anti-tangle rotation mode and standard rotation mode. Alternatively, multiple rotation modes can be divided into three categories: first rotation mode, second rotation mode, and third rotation mode, corresponding to easily tangled types, ordinary types, and non-tangled types, etc. Such flexible adjustments and changes do not deviate from the principles and scope of the present invention and should all be limited to the protection scope of the present invention.

[0098] Preferably, the rotation mode of the washing machine of the present invention includes a standard rotation mode and an anti-tangling rotation mode. The step of "obtaining the rotation mode corresponding to the type of clothing" specifically includes: if the type of clothing is prone to tangling, then the corresponding rotation mode is the anti-tangling rotation mode.

[0099] Furthermore, the step of "obtaining the rotation mode corresponding to the type of clothing" also includes: if the type of clothing is not easily tangled, then the corresponding rotation mode is the standard rotation mode.

[0100] In other words, the inner drum of the washing machine of the present invention has two main types of rotation modes: a standard rotation mode and an anti-tangling rotation mode. When the fresh air mode is activated, if the type of clothing in the inner drum is prone to tangling, such as towels, blankets, and bath towels, the inner drum operates in the anti-tangling rotation mode. This effectively prevents the clothing from tangling. For example, the inner drum can rotate at a higher speed to avoid tangling, or it can rotate at a centrifugal speed to make the clothing stick to the inner drum wall to avoid tangling, and so on. When the type of clothing in the inner drum is not prone to tangling, the inner drum can operate in the standard rotation mode.

[0101] Preferably, the anti-tangling rotation mode of the present invention has multiple rotation speed stages, in which the inner drum rotates at different speeds. By setting multiple different rotation speed stages, when the inner drum rotates at different speeds, it is beneficial to make the clothes in the inner drum change position quickly, thereby making the clothes in the inner drum come into more full contact with the fresh air or hot air entering the inner drum.

[0102] It should be noted that the invention does not limit the number of rotational speed stages. For example, the anti-winding rotational mode can have two, three, or more rotational speed stages.

[0103] Furthermore, it should be noted that, in practical applications, those skilled in the art may set only one anti-tangling rotation mode. As long as it is determined that the type of clothing in the inner drum is prone to tangling, the inner drum will operate according to this anti-tangling rotation mode. Alternatively, multiple different anti-tangling rotation modes may be set. After determining that the type of clothing is prone to tangling, the appropriate anti-tangling rotation mode can be selected based on the weight of the clothing, etc. Such flexible adjustments and changes do not deviate from the principles and scope of the present invention and should all be limited to the protection scope of the present invention.

[0104] Preferably, the washing machine of the present invention has at least two anti-tangling rotation modes, and the minimum rotation speed in the multiple rotation speed stages of different anti-tangling rotation modes is different. When the type of clothes in the inner drum is easy to tangle, the control method of the present invention further includes: obtaining the weight of the clothes in the inner drum; obtaining the anti-tangling rotation mode corresponding to the weight of the clothes; wherein, the magnitude of the minimum rotation speed in the multiple rotation speed stages of the anti-tangling rotation mode is positively related to the weight of the clothes.

[0105] In other words, the inner drum of the washing machine of the present invention has multiple different anti-tangling rotation modes, which can be two, three or more. The minimum rotation speed of different anti-tangling rotation modes is different. After determining that the type of clothes in the inner drum are prone to tangling, a more suitable anti-tangling rotation mode is selected based on the weight of the clothes in the inner drum. The heavier the clothes, the higher the minimum rotation speed of the corresponding anti-tangling rotation mode. This setting is more conducive to preventing clothes from tangling.

[0106] It should be noted that the steps of determining the type of clothing and determining the weight of clothing can be performed simultaneously, or the steps of determining the type of clothing can be performed first and then the steps of determining the weight of clothing. Such flexible adjustments and changes do not deviate from the principles and scope of the present invention and should be limited to the protection scope of the present invention.

[0107] Preferably, the anti-tangling rotation mode of the present invention includes a rotation speed stage where the rotation speed reaches the centrifugal speed. Here, the centrifugal speed refers to the rotation speed at which the centrifugal acceleration of the inner surface of the inner drum is greater than the acceleration due to gravity. When the inner drum rotates at the centrifugal speed, the clothes inside will adhere to the inner surface of the inner drum, creating a cavity in the middle of the inner drum. Fresh air entering the inner drum is then discharged through the through-holes in the inner drum wall, which facilitates the penetration of the incoming fresh air into the clothes, thus better preventing odors from developing in the clothes inside the inner drum.

[0108] Preferably, the rotational speed increases sequentially in the multiple rotational stages of the anti-entanglement rotation mode.

[0109] For example, the present invention has two anti-winding rotation modes, namely a first anti-winding rotation mode and a second anti-winding rotation mode. The first anti-winding rotation mode has three rotation speed stages, namely rotation speed A, rotation speed B and rotation speed C. The second anti-winding rotation mode has two rotation speed stages, namely rotation speed B and rotation speed C. Among them, rotation speed A < rotation speed B < rotation speed C, rotation speed C is the centrifugal speed, rotation speed A is the lowest rotation speed in the first anti-winding rotation mode, and rotation speed B is the lowest rotation speed in the second anti-winding rotation mode.

[0110] If the type of clothing is prone to tangling, and the weight of the clothing is less than a preset value, the corresponding anti-tangling rotation mode is the first anti-tangling rotation mode; if the weight of the clothing is not less than the preset value, the corresponding anti-tangling rotation mode is the second anti-tangling rotation mode.

[0111] When the weight of the clothes in the inner drum is less than the preset value, it means that there are relatively few clothes in the inner drum. In this case, the inner drum is made to operate in the first anti-tangling rotation mode. Specifically, the inner drum speed is first accelerated to speed A, the inner drum is rotated at speed A for a period of time and then accelerated to speed B, the inner drum is run at speed B for a period of time and then accelerated to speed C (i.e., centrifugal speed), and finally the inner drum is rotated at the centrifugal speed.

[0112] When the weight of the clothes in the inner drum is greater than or equal to the preset value, it indicates that there are a lot of clothes in the inner drum. In this case, the inner drum is made to operate in the second anti-tangling rotation mode. Specifically, the rotation speed of the inner drum is first accelerated to speed B. After the inner drum rotates at speed B for a period of time, the rotation speed of the inner drum is accelerated to speed C (i.e., centrifugal speed), and then the inner drum rotates at the centrifugal speed.

[0113] It should be noted that the number of rotational speed stages in the first anti-winding rotational mode is not limited to three. For example, the number of rotational speed stages in the first anti-winding rotational mode can be set to two or four. Similarly, the number of rotational speed stages in the second anti-winding rotational mode is not limited to two. For example, the number of rotational speed stages in the second anti-winding rotational mode can be set to three or four, and so on. Such flexible adjustments and changes do not deviate from the principles and scope of the present invention and should all be limited to the protection scope of the present invention.

[0114] Furthermore, it should be noted that the present invention does not limit the specific value of the rotation speed in each rotation stage. Those skilled in the art can flexibly set the specific value of the rotation speed in each rotation stage based on experiments or experience in practical applications, as long as it helps to prevent the clothes in the inner drum from getting tangled.

[0115] Furthermore, it should be noted that the present invention does not limit the specific value of the preset value. Those skilled in the art can flexibly set the specific value of the preset value based on experiments or experience in practical applications, as long as the critical point limited by the preset value can be used to determine whether the rotation speed of the inner cylinder can be directly accelerated to the centrifugal speed.

[0116] Preferably, the standard rotation mode of the present invention has multiple rotation speed stages, in which the inner cylinder rotates at different speeds. The lowest speed in the multiple rotation speed stages of the anti-winding rotation mode is greater than the lowest speed in the multiple rotation speed stages of the standard rotation mode.

[0117] When the clothes in the inner drum are not the type that are easy to tangle, the inner drum operates according to the standard rotation mode. Specifically, the inner drum rotates at multiple different speeds, which can be two different speeds, three different speeds, or more different speeds. By making the inner drum rotate at different speeds, it is beneficial to make the clothes in the inner drum constantly change position, so that the clothes can have more full contact with the fresh air entering the inner drum, which is more conducive to preventing the clothes in the inner drum from producing odors.

[0118] It should be noted that the rotational speeds in multiple rotational speed stages can all be less than the centrifugal speed, or the rotational speed in one rotational speed stage can reach the centrifugal speed, etc. Such flexible adjustments and changes do not deviate from the principles and scope of the present invention and should all be limited to the protection scope of the present invention.

[0119] Furthermore, it should be noted that the rotational speeds in the multiple speed stages can increase sequentially, or decrease sequentially, or fluctuate up and down, etc. Such flexible adjustments and changes do not deviate from the principles and scope of the present invention and should all be limited to the protection scope of the present invention.

[0120] Preferably, the multiple speed stages of the standard rotation mode include a speed stage where the speed reaches the centrifugal speed. That is, among the multiple speed stages in the standard rotation mode, there is one stage where the speed reaches the centrifugal speed.

[0121] For example, the standard rotation mode has four rotational speed stages executed sequentially, with the speeds of the four speed stages being speed a, speed b, speed c, and speed d, wherein one of speeds a, speed b, speed c, and speed d is a centrifugal speed, and the other three speeds are all less than the centrifugal speed.

[0122] Preferably, the rotational speed increases sequentially in the multiple rotational speed stages of the standard rotational mode.

[0123] For example, the standard rotation mode has four rotation speed stages executed sequentially, namely speed a, speed b, speed c, and speed d, wherein speed a < speed b < speed c < speed d, and speed d is the centrifugal speed. Specifically, speed a is 20 rpm to 45 rpm, speed b is 40 rpm to 65 rpm, speed c is 60 rpm to 85 rpm, and speed d is the centrifugal speed, preferably greater than 90 rpm.

[0124] In the standard rotation mode, the inner cylinder's rotation speed is first accelerated to speed a, and the inner cylinder rotates at speed a for 5 to 50 seconds. Then it is accelerated to speed b, and the inner cylinder rotates at speed b for 5 to 30 seconds. Then it is accelerated to speed c, and the inner cylinder rotates at speed c for 5 to 20 seconds. Finally, it is accelerated to speed d.

[0125] Example 2

[0126] The present invention also provides a control method for a washing machine. As shown in Figure 3, when executing the fresh air mode, the control method of the present invention includes the following steps: S100: obtaining the weight of the clothes in the inner drum; S200: obtaining the rotation mode corresponding to the weight of the clothes; S300: causing the inner drum to operate according to the rotation mode. At least one rotation mode has multiple different speed stages, and the clothes handling drum rotates at different speed stages.

[0127] In other words, the washing machine of the present invention has multiple different rotation modes and multiple different speed stages. When the washing machine is in fresh air mode, it can determine the appropriate rotation mode according to the weight of the clothes in the inner drum. The rotation mode has multiple different speed stages. By making the inner drum rotate at different speeds, it can better change the position of the clothes in the inner drum, so that the clothes in the inner drum can have more full contact with the incoming fresh air, which is more conducive to preventing the clothes in the inner drum from producing odors and improving the fresh air exchange effect.

[0128] It should be noted that the above control methods are also applicable to dryers and washer-dryer combos. Specifically, when the drying mode is executed, by adopting a rotation mode that matches the weight of the clothes in the drying drum, it is more conducive to the clothes in the drying drum changing position quickly, so that the clothes in the inner drum can have more full contact with the hot air blown in, thereby improving the drying effect.

[0129] Furthermore, it should be noted that for washing machines with a fresh air function, a button to activate the fresh air function can be set on the control panel. When the user selects the fresh air function, the washing machine will automatically execute the fresh air mode after completing the washing program. If the user does not select the fresh air function, the washing machine will not execute the fresh air mode after completing the washing program. Alternatively, the washing machine can be set to automatically determine whether to execute the fresh air mode. One or more preset conditions for activating the fresh air function can be stored in the controller of the washing machine. When the preset conditions are met, the washing machine will automatically execute the fresh air mode after completing the washing program, etc. Such flexible adjustments and changes do not deviate from the principles and scope of this invention and should be limited to the protection scope of this invention.

[0130] Furthermore, it should be noted that each rotation mode can have multiple different speed stages, or one rotation mode can have only one speed stage, while the other rotation modes have multiple different speed stages, and so on. Such flexible adjustments and changes do not deviate from the principles and scope of the present invention and should all be limited to the protection scope of the present invention.

[0131] The technical solution of the present invention will be described in detail below with reference to two preferred examples.

[0132] In a first preferred embodiment, the control method of the present invention includes the following steps: S100: obtaining the weight of the clothes in the inner drum; S200: obtaining the rotation mode corresponding to the weight of the clothes; S300: causing the inner drum to operate according to the rotation mode. Each rotation mode has multiple different speed stages, during which the inner drum rotates at different speeds. Furthermore, each rotation mode has a speed stage where the speed reaches the centrifugal speed. The first speed stage among the multiple speed stages is the initial speed stage. The speed of the initial speed stage differs in different rotation modes, and the speed of the initial speed stage is less than the centrifugal speed.

[0133] In other words, in this embodiment, each rotation mode has multiple different rotation speed stages, such as two rotation speed stages, three rotation speed stages, or four rotation speed stages. In different rotation speed stages, the inner drum rotates at different speeds. The first rotation speed stage is referred to as the initial rotation speed stage. The initial rotation speed stages of different rotation modes are different, that is, the weight of the clothes in the inner drum is different, and the rotation speed of the inner drum in the initial rotation speed stage is different. Furthermore, the rotation speed of the initial rotation speed stage in each rotation mode is less than the centrifugal speed.

[0134] The centrifugal speed refers to the rotational speed when the centrifugal acceleration of the inner surface of the inner drum is greater than the gravitational acceleration. When the inner drum rotates at the centrifugal speed, the clothes inside will stick to the inner surface of the inner drum and rotate synchronously with it. The speed less than the centrifugal speed refers to the rotational speed when the centrifugal acceleration of the inner surface of the inner drum is less than the gravitational acceleration. When the rotational speed of the inner drum is less than the centrifugal speed, the clothes inside the inner drum will fall off the inner surface of the inner drum after rotating to a certain height.

[0135] In the first rotational speed stage, i.e. the initial rotational speed stage, the inner drum rotates at a speed less than the centrifugal speed to change the position of the clothes inside the drum. When the inner drum rotates at the centrifugal speed, the clothes only stick to the drum wall, protecting the clothes and reducing wear. In addition, it can create a cavity in the middle of the inner drum, and the fresh air entering the inner drum is discharged through the through holes on the drum wall, which helps the incoming fresh air to penetrate the clothes, thus further preventing the clothes inside the drum from developing odors.

[0136] For example, the weight of the clothes in the inner drum is divided into three levels, from light to heavy: light load, medium load, and heavy load. The rotation mode corresponding to light load is the light load rotation mode, which includes four speed stages. The rotation mode corresponding to medium load is the medium load rotation mode, which includes three speed stages. The rotation mode corresponding to heavy load is the heavy load rotation mode, which includes two speed stages.

[0137] In the light load rotation mode, the speeds of the four speed stages can be speed A, speed B, speed C, and speed D, respectively. In the medium load rotation mode, the speeds of the three speed stages can be speed B, speed C, and speed D, respectively. In the heavy load rotation mode, the speeds of the two speed stages can be speed C and speed D, respectively. Speeds A, B, and C are all less than speed D, and speed D is the centrifugal speed.

[0138] Here, speed A is the initial speed in the light load rotation mode. When the weight of the clothes in the inner drum is light, the inner drum will run at speed A for a period of time. Speed ​​B is the initial speed in the medium load rotation mode. When the weight of the clothes in the inner drum is medium, the inner drum will run at speed B for a period of time. Speed ​​C is the initial speed in the heavy load rotation mode. When the weight of the clothes in the inner drum is heavy, the inner drum will run at speed C for a period of time.

[0139] It should be noted that the light load rotation mode may include only two or three speed stages. Similarly, the medium load rotation mode may include two or four speed stages, the heavy load rotation mode may include three or four speed stages, and so on. Such adjustments and changes to the number of speed stages in each rotation mode do not deviate from the principles and scope of the present invention and should be limited to the protection scope of the present invention.

[0140] Furthermore, it should be noted that the weight classification of clothing is not limited to three levels; for example, it can also be two, four, or more levels. Such flexible adjustments and changes do not deviate from the principles and scope of this invention and should all be limited to the protection scope of this invention.

[0141] Furthermore, it should be noted that each rotation mode has multiple speed stages with different rotation speeds. The rotation speeds of these multiple speed stages can increase sequentially, or they can increase first, then decrease, and then increase again, etc. Such flexible adjustments and changes do not deviate from the principles and scope of this invention and should be limited to the protection scope of this invention.

[0142] Preferably, the rotational speed in the initial rotational stage of different rotational modes is positively correlated with the weight of the clothing.

[0143] In other words, the heavier the clothes in the inner drum, the higher the rotation speed of the inner drum in the initial stage. When there are many clothes in the inner drum, making the inner drum rotate at a higher speed at the beginning helps to prevent the clothes from rolling and tangling, and also makes it easier for the clothes in the inner drum to change position quickly. When there are few clothes in the inner drum, making the inner drum rotate at a lower speed at the beginning helps to reduce the friction between the clothes and the inner drum while ensuring that the clothes in the inner drum can change position, thereby reducing the wear and tear on the clothes.

[0144] Preferably, the rotational speed increases sequentially across multiple rotational stages. That is, in each rotational mode, the rotational speed of the inner drum gradually increases until it reaches the centrifugal speed. This setting not only changes the position of the clothes in the inner drum but also helps to distribute the clothes evenly, thereby reducing the probability of drum collision.

[0145] Let's take the example of dividing the weight of the clothes in the inner drum into light load, medium load, and heavy load. The rotation mode corresponding to light load is called light load rotation mode, which includes four speed stages (speed A, speed B, speed C, and speed D). The rotation mode corresponding to medium load is called medium load rotation mode, which includes three speed stages (speed B, speed C, and speed D). The rotation mode corresponding to heavy load is called heavy load rotation mode, which includes two speed stages (speed C and speed D). Here, speed A < speed B < speed C < speed D, and speed D is the centrifugal speed.

[0146] Preferably, different rotation modes have different numbers of rotation speed stages. That is, the number of rotation speed stages in the inner drum varies depending on the weight of the clothes in it, and the rotation mode used by the inner drum has different numbers of rotation speed stages when executing programs such as drying mode or fresh air mode.

[0147] Preferably, the number of rotational speed stages in the rotation mode is inversely related to the weight of the clothes in the inner drum. That is, the heavier the clothes in the inner drum, the fewer the number of rotational speed stages in the corresponding rotation mode. This setting is more conducive to the continuous repositioning of the clothes in the inner drum.

[0148] Preferably, the duration of the same speed phase varies in different rotation modes. That is, different rotation modes have the same speed phase, but the duration of that speed phase is different.

[0149] Let's take the example of dividing the weight of the clothes in the inner drum into light load, medium load, and heavy load. The rotation mode corresponding to light load is called light load rotation mode, which includes four speed stages (A speed, B speed, C speed, and D speed). The rotation mode corresponding to medium load is called medium load rotation mode, which includes three speed stages (B speed, C speed, and D speed). The rotation mode corresponding to heavy load is called heavy load rotation mode, which includes two speed stages (C speed and D speed).

[0150] Among them, the duration of the inner cylinder rotating at speed B under light load is different from the duration of the inner cylinder rotating at speed B under medium load. The duration of the inner cylinder rotating at speed C under light load, the duration of the inner cylinder rotating at speed C under medium load, and the duration of the inner cylinder rotating at speed C under heavy load are all different.

[0151] Preferably, the duration of the same rotational speed phase in different rotation modes is positively correlated with the weight of the clothing. That is, in the same rotational speed phase, the heavier the clothing in the inner drum, the longer the duration of that rotational speed phase in the inner drum.

[0152] Preferably, the durations of different speed stages within the same rotational mode are different. That is, each rotational mode has multiple speed stages, and the multiple speed stages within the same rotational mode have different durations.

[0153] The technical solution of this embodiment will be described below with reference to a preferred example.

[0154] The weight of the clothes in the inner drum is divided into three levels, from light to heavy: light load, medium load, and heavy load. The light load rotation mode has four speed stages, the medium load rotation mode has three speed stages, and the heavy load rotation mode has two speed stages.

[0155] The speeds of the four speed stages in the light load rotation mode are speed A, speed B, speed C and speed D, the speeds of the three speed stages in the medium load rotation mode are speed B, speed C and speed D, and the speeds of the two speed stages in the heavy load rotation mode are speed C and speed D.

[0156] Among them, A has a speed of 20 rpm to 45 rpm, B has a speed of 40 rpm to 65 rpm, C has a speed of 60 rpm to 85 rpm, and D has a speed greater than 90 rpm.

[0157] In the light load rotation mode, the inner cylinder rotates at speed A for 5 to 50 seconds, at speed B for 5 to 30 seconds, at speed C for 5 to 20 seconds, and at speed D for 10 to 120 seconds.

[0158] In the medium-load rotation mode, the inner cylinder rotates at speed B for 10 to 50 seconds, at speed C for 10 to 30 seconds, and at speed D for 20 to 120 seconds.

[0159] In the heavy-load rotation mode, the inner cylinder rotates at speed C for 15 to 50 seconds, and rotates at speed D for 30 to 120 seconds.

[0160] In a second preferred example: the control method of the present invention includes the following steps: S100: obtaining the weight of the clothes in the inner drum; S200: obtaining the rotation mode corresponding to the weight of the clothes; S300: causing the inner drum to operate according to the rotation mode. The rotation mode includes a first rotation mode and multiple second rotation modes. The first rotation mode has a rotation speed stage in which the inner drum rotates at a centrifugal speed. Each second rotation mode has multiple different rotation speed stages in which the inner drum rotates at different speeds. Each second rotation mode has a stage where the rotation speed reaches the centrifugal speed. The first rotation speed stage in the multiple rotation speed stages of the second rotation mode is the initial rotation speed stage. The initial rotation speed stages in different rotation modes have different speeds, and the speed in the initial rotation speed stage is less than the centrifugal speed.

[0161] Specifically, step S200, "obtaining the rotation mode corresponding to the weight of the clothing", includes: if the weight of the clothing is less than a preset value, the rotation mode corresponding to the weight of the clothing is the first rotation mode; if the weight of the clothing is not less than the preset value, the rotation mode corresponding to the weight of the clothing is the second rotation mode.

[0162] In other words, this embodiment includes two different rotation modes: a first rotation mode and a second rotation mode.

[0163] There is only one first rotation mode. When the weight of the clothes in the inner drum is less than the preset value, the inner drum operates according to the first rotation mode. The first rotation mode has only one speed stage. During this speed stage, the inner drum rotates at a centrifugal speed.

[0164] If the weight of the clothes in the inner drum is less than the preset value, it indicates that the amount of clothes is relatively small. In this case, the inner drum can be directly accelerated to centrifugal speed. This first rotation mode can also be called the light load rotation mode.

[0165] There can be multiple second rotation modes, including two or more. Each second rotation mode has multiple different speed stages, such as two, three, or four speed stages. In different speed stages, the inner drum rotates at different speeds. Each second rotation mode has a speed stage where the speed reaches the centrifugal speed. Furthermore, the first speed stage of each second rotation mode is called the initial speed stage. The initial speed stages of different second rotation modes are different, meaning that the speed of the inner drum in the initial speed stage is different depending on the weight of the clothes in the inner drum. Moreover, the speed of the initial speed stage in each second rotation mode is less than the centrifugal speed.

[0166] The centrifugal speed refers to the rotational speed when the centrifugal acceleration of the inner surface of the inner drum is greater than the gravitational acceleration. When the inner drum rotates at the centrifugal speed, the clothes inside will stick to the inner surface of the inner drum and rotate synchronously with it. The speed less than the centrifugal speed refers to the rotational speed when the centrifugal acceleration of the inner surface of the inner drum is less than the gravitational acceleration. When the rotational speed of the inner drum is less than the centrifugal speed, the clothes inside the inner drum will fall off the inner surface of the inner drum after rotating to a certain height.

[0167] When the weight of the clothes in the inner drum is greater than or equal to the preset value, it indicates that there are too many clothes in the inner drum, which is prone to uneven distribution of clothes. In this case, the inner drum adopts the second rotation mode. In the first rotation stage, that is, the initial rotation stage, the inner drum rotates at a speed less than the centrifugal speed, which can change the position of the clothes in the inner drum. This helps to distribute the clothes in the inner drum more evenly, which is more conducive to the effect of fresh air mode and drying mode, and reduces the probability of the inner drum colliding when rotating at centrifugal speed.

[0168] For example, the weight of the clothes in the inner drum is divided into three levels, from light to heavy: light load (less than a preset value), medium load, and heavy load. The rotation mode corresponding to light load is the light load rotation mode, which belongs to the first rotation mode and has only one speed stage. The rotation mode corresponding to medium load is the medium load rotation mode, which includes three speed stages. The rotation mode corresponding to heavy load is the heavy load rotation mode, which includes two speed stages. Both the medium load rotation mode and the heavy load rotation mode belong to the second rotation mode.

[0169] In the light load rotation mode, the rotation speed of the three rotation speed stages is speed c. In the medium load rotation mode, the rotation speeds of the three rotation speed stages can be speed a, speed b, and speed c, respectively. In the heavy load rotation mode, the rotation speeds of the two rotation speed stages can be speed b and speed c, respectively. Speeds a and b are both less than speed c, and speed c is the centrifugal speed.

[0170] Specifically, when the weight of the clothes in the inner drum is light, the inner drum speed directly accelerates to speed c; speed a is the initial speed of the medium load rotation mode. When the weight of the clothes in the inner drum is medium, the inner drum first runs at speed a for a period of time, then accelerates to speed b for a period of time, and finally accelerates to speed c; speed b is the initial speed of the heavy load rotation mode. When the weight of the clothes in the inner drum is heavy, the inner drum first runs at speed b for a period of time, and then accelerates to speed c.

[0171] It should be noted that the present invention does not limit the specific value of the preset value. Those skilled in the art can flexibly set the specific value of the preset value based on experiments or experience in practical applications, as long as the critical point limited by the preset value can be used to determine whether the rotation speed of the inner cylinder can be directly accelerated to the centrifugal speed.

[0172] Furthermore, it should be noted that the medium-load rotation mode may include two or four speed stages, the heavy-load rotation mode may include three or four speed stages, and so on. Such adjustments and changes to the number of speed stages in each second rotation mode do not deviate from the principles and scope of the present invention and should be limited to the protection scope of the present invention.

[0173] Furthermore, it should be noted that the weight classification of clothing is not limited to three levels. For example, there could be four or more levels, or even two levels. In such cases, there would only be one second rotation mode. Such flexible adjustments and changes do not deviate from the principles and scope of this invention and should all be limited to the protection scope of this invention.

[0174] Furthermore, it should be noted that each second rotation mode has multiple rotation speed stages with different rotation speeds. The rotation speeds of the multiple rotation speed stages can increase sequentially, or they can increase first and then decrease and then increase again, etc. Such flexible adjustments and changes do not deviate from the principles and scope of the present invention and should be limited to the protection scope of the present invention.

[0175] Preferably, the rotational speed in the initial rotational stage of different second rotational modes is positively correlated with the weight of the clothing.

[0176] In other words, when the inner drum is running in the second rotation mode, the heavier the clothes in the inner drum, the higher the rotation speed of the inner drum in the initial stage. When there are many clothes in the inner drum, the inner drum rotates at a higher speed at the beginning, which helps to prevent the clothes from rolling and tangling, and makes it easier for the clothes in the inner drum to change position. When there are not many clothes in the inner drum, the inner drum rotates at a lower speed at the beginning, which helps to reduce the friction between the clothes and the inner drum while ensuring that the clothes in the inner drum can change position, thereby reducing the wear and tear on the clothes.

[0177] Preferably, the rotational speed increases sequentially across multiple rotational stages. That is, in each second rotational mode, the rotational speed of the inner drum gradually increases until it reaches the centrifugal speed. This setting allows the clothes in the inner drum to change position quickly and also helps to distribute the clothes evenly, thereby reducing the probability of drum collision.

[0178] Taking the case where the weight of the clothes in the inner drum is not less than a preset value and is divided into medium load and heavy load as an example, the rotation mode corresponding to the medium load is called the medium load rotation mode, which includes three speed stages (speed a, speed b, and speed c). The rotation mode corresponding to the heavy load is called the heavy load rotation mode, which includes two speed stages (speed b and speed c). Among them, speed a < speed b < speed c, and speed c is the centrifugal speed.

[0179] Preferably, different second rotation modes have different numbers of rotation speed stages. That is, when the inner drum is running in the second rotation mode, the number of rotation speed stages of the second rotation mode used by the inner drum varies depending on the weight of the clothes in the inner drum, such as when executing programs such as drying mode or fresh air mode.

[0180] Preferably, the number of rotational speed stages in the second rotation mode is inversely related to the weight of the clothes in the inner drum. That is, the heavier the clothes in the inner drum, the fewer the number of rotational speed stages in the corresponding second rotation mode. This setting makes it easier to change the position of the clothes in the inner drum.

[0181] Preferably, the duration of the same rotational speed phase differs in different second rotational modes. That is, different second rotational modes have the same rotational speed phase, but the duration of that rotational speed phase is different.

[0182] Taking the case where the weight of the clothes in the inner drum is not less than a preset value and is divided into medium load and heavy load as an example, the rotation mode corresponding to medium load is called medium load rotation mode, which includes three speed stages (speed a, speed b and speed c), and the rotation mode corresponding to heavy load is called heavy load rotation mode, which includes two speed stages (speed b and speed c).

[0183] The duration of the inner cylinder rotating at speed b under medium load is different from the duration of the inner cylinder rotating at speed b under heavy load.

[0184] Preferably, the duration of the same rotational speed phase in different second rotational modes is positively correlated with the weight of the clothing. That is, in the same rotational speed phase, the heavier the clothing in the inner drum, the longer the duration of that rotational speed phase in the inner drum.

[0185] Preferably, the durations of different speed stages within the same second rotational mode are different. That is, each second rotational mode has multiple speed stages, and the multiple speed stages within the same second rotational mode have different durations.

[0186] The technical solution of this embodiment will be described below with reference to a preferred example.

[0187] The weight of the clothes in the inner drum is divided into three levels, from light to heavy: light load (less than the preset value), medium load, and heavy load. The rotation mode corresponding to light load is the light load rotation mode, which includes one speed stage. The rotation mode corresponding to medium load is the medium load rotation mode, which includes three speed stages. The rotation mode corresponding to heavy load is the heavy load rotation mode, which includes two speed stages.

[0188] In the light load rotation mode, the rotation speed of the three rotation speed stages is speed c; in the medium load rotation mode, the rotation speeds of the three rotation speed stages are speed a, speed b, and speed c; and in the heavy load rotation mode, the rotation speeds of the two rotation speed stages are speed b and speed c.

[0189] Among them, a) is a speed of 40 rpm to 65 rpm, b) is a speed of 60 rpm to 85 rpm, and c) is a speed greater than 90 rpm.

[0190] In the light load rotation mode, the inner cylinder speed is directly accelerated to speed c, and then rotates at speed c for a duration of 10s to 120s.

[0191] In the medium-load rotation mode, the inner cylinder speed is first accelerated to speed a, and then rotated at speed a for 10s to 50s. Then the inner cylinder speed is accelerated to speed b and rotated at speed b for 10s to 30s. Finally, the inner cylinder speed is accelerated to speed c and rotated at speed c for 20s to 120s.

[0192] In the heavy-load rotation mode, the inner cylinder speed is first accelerated to speed b and rotated at speed b for a duration of 15s to 50s, and then the inner cylinder speed is accelerated to speed c and rotated at speed c for a duration of 30s to 120s.

[0193] It should be noted that the above control methods are all executed by the controller of the washing machine of the present invention.

[0194] Example 3

[0195] The present invention also provides a control method for a washing machine. As shown in Figure 4, when executing the fresh air mode, the control method of the present invention includes the following steps: S100: obtaining the material of the clothes in the inner drum; S200: obtaining the rotation mode corresponding to the material of the clothes; S300: causing the inner drum to operate according to the rotation mode.

[0196] In other words, the inner drum of the washing machine of the present invention has multiple different rotation modes. When the fresh air mode is executed, the appropriate rotation mode can be selected according to the material of the clothes in the inner drum. In different rotation modes, the inner drum has different rotation methods and speeds. By making the rotation mode of the inner drum compatible with the material of the clothes in the inner drum, it is beneficial to reduce the wear and tear on the clothes and avoid damage to the clothes.

[0197] It should be noted that the above control methods are also applicable to dryers and washer-dryer combos. Specifically, when executing the drying mode, by adopting a rotation mode that is compatible with the material of the clothes in the drying drum, it is beneficial to reduce the wear and tear on the clothes and avoid damage to the clothes.

[0198] Furthermore, it should be noted that for washing machines with a fresh air function, a button to activate the fresh air function can be set on the control panel. When the user selects the fresh air function, the washing machine will automatically execute the fresh air mode after completing the washing program. If the user does not select the fresh air function, the washing machine will not execute the fresh air mode after completing the washing program. Alternatively, the washing machine can be set to automatically determine whether to execute the fresh air mode. One or more preset conditions for activating the fresh air function can be stored in the controller of the washing machine. When the preset conditions are met, the washing machine will automatically execute the fresh air mode after completing the washing program, etc. Such flexible adjustments and changes do not deviate from the principles and scope of this invention and should be limited to the protection scope of this invention.

[0199] Furthermore, it should be noted that, in practical applications, those skilled in the art can divide multiple different rotation modes into two categories: low-wear rotation mode and standard rotation mode. Alternatively, multiple rotation modes can be divided into three categories: first rotation mode, second rotation mode, and third rotation mode, corresponding to easily worn materials, ordinary materials, and wear-resistant materials, respectively. Such flexible adjustments and changes do not deviate from the principles and scope of the present invention and should all be limited to the protection scope of the present invention.

[0200] Preferably, the rotation mode of the washing machine of the present invention includes a standard rotation mode and a low-wear rotation mode. The step of "obtaining the rotation mode corresponding to the material of the clothing" specifically includes: if the material of the clothing is a wear-prone material, the corresponding rotation mode is the low-wear rotation mode; if the material of the clothing is not a wear-prone material, the corresponding rotation mode is the standard rotation mode.

[0201] In other words, the inner drum of the washing machine of this invention has two main rotation modes: a standard rotation mode and a low-wear rotation mode. When the fresh air mode is activated, if the clothes in the inner drum are made of easily worn materials, such as wool and silk, the inner drum operates in the low-wear rotation mode. This effectively reduces wear and tear on the clothes and prevents damage. For example, the inner drum can rotate at a lower speed to reduce wear, or it can rotate at a centrifugal speed to make the clothes stick to the drum wall, thus reducing wear. When the clothes in the inner drum are not made of easily worn materials, such as cotton, linen, and synthetic fibers, the inner drum operates in the standard rotation mode, which helps to prevent odors from developing and ensures the fresh air effect.

[0202] It should be noted that, in practical applications, those skilled in the art can set only one low-wear rotation mode. As long as it is determined that the material of the clothes in the inner drum is easily worn, the inner drum will operate according to this low-wear rotation mode. Alternatively, multiple different low-wear rotation modes can be set. After determining that the material of the clothes is easily worn, the appropriate low-wear rotation mode can be selected according to the weight of the clothes, etc. Such flexible adjustments and changes do not deviate from the principles and scope of the present invention and should all be limited to the protection scope of the present invention.

[0203] Preferably, the washing machine of the present invention has at least two low-wear rotation modes. When the material of the clothes is a wear-prone material, the control method of the present invention further includes: obtaining the weight of the clothes in the inner drum; and obtaining the low-wear rotation mode corresponding to the weight of the clothes.

[0204] In other words, the inner drum of the washing machine of the present invention has multiple different low-wear rotation modes, which can be two, three or more. After determining that the material of the clothes in the inner drum is a wear-prone material, a more suitable low-wear rotation mode is selected based on the weight of the clothes in the inner drum. This setting is more conducive to reducing the wear and tear on the clothes and also more conducive to ensuring the fresh air effect.

[0205] It should be noted that the steps of obtaining the material of the clothing and obtaining the weight of the clothing can be performed simultaneously, or the steps of obtaining the material of the clothing can be performed first and then the steps of obtaining the weight of the clothing. Such flexible adjustments and changes do not deviate from the principles and scope of the present invention and should be limited to the protection scope of the present invention.

[0206] Furthermore, it should be noted that the low-wear rotation mode may have one speed stage or multiple different speed stages, etc. Such flexible adjustments and changes do not deviate from the principles and scope of the present invention and should all be limited to the protection scope of the present invention.

[0207] Preferably, the low-wear rotation mode of the present invention has a rotational speed stage in which the rotational speed reaches the centrifugal speed.

[0208] The centrifugal speed refers to the rotational speed when the centrifugal acceleration of the inner surface of the inner drum is greater than the gravitational acceleration. When the inner drum rotates at the centrifugal speed, the clothes in the inner drum will stick to the inner surface of the inner drum. As the inner drum rotates synchronously, it protects the clothes and reduces wear. In addition, it can form a cavity in the middle of the inner drum. The fresh air entering the inner drum is discharged through the through holes on the inner drum wall, which helps the incoming fresh air to penetrate the clothes, thus making it more effective in preventing the clothes in the inner drum from producing odors.

[0209] Preferably, the low-wear rotation mode of the present invention includes a first low-wear rotation mode and a second low-wear rotation mode. When the first low-wear rotation mode is executed, the rotation speed of the inner cylinder is directly accelerated to the centrifugal speed. When the second low-wear rotation mode is executed, the rotation speed of the inner cylinder is first accelerated to a set speed, and the inner cylinder runs at the set speed for a set time before being accelerated to the centrifugal speed.

[0210] The step of “obtaining the low-wear rotation mode corresponding to the weight of the garment” specifically includes: if the weight of the garment is less than a preset value, the corresponding low-wear rotation mode is the first low-wear rotation mode; if the weight of the garment is not less than the preset value, the corresponding low-wear rotation mode is the second low-wear rotation mode.

[0211] The washing machine of this invention has two low-wear rotation modes in its inner drum: a first low-wear rotation mode and a second low-wear rotation mode. When the weight of the clothes in the inner drum is less than a preset value, it indicates that there are relatively few clothes in the inner drum. In this case, the inner drum operates according to the first low-wear rotation mode, specifically, the rotation speed of the inner drum is directly accelerated to the centrifugal speed, and then the inner drum rotates at the centrifugal speed. When the weight of the clothes in the inner drum is greater than or equal to the preset value, it indicates that there are relatively many clothes in the inner drum. In this case, the inner drum operates according to the second low-wear rotation mode, specifically, the rotation speed of the inner drum is first accelerated to a set speed, the inner drum rotates at the set speed for a set time, and then the rotation speed of the inner drum is accelerated to the centrifugal speed, and then the inner drum rotates at the centrifugal speed.

[0212] When the clothes in the inner drum are relatively light, the inner drum's rotation speed is directly accelerated to the centrifugal speed to minimize wear and tear on the clothes. When the clothes in the inner drum are relatively heavy, the inner drum's rotation speed is first accelerated to the set speed and then rotated at the set speed for a set time. When the inner drum rotates at the set speed, since the set speed is less than the centrifugal speed, the clothes in the inner drum will fall off the inner surface of the inner drum after rotating to a certain height. This allows the clothes in the inner drum to quickly change position, which is beneficial for the clothes to have more full contact with the fresh air entering the inner drum and also helps to distribute the clothes in the inner drum evenly. Then the inner drum's rotation speed is accelerated to the centrifugal speed.

[0213] It should be noted that the present invention does not limit the specific value of the preset value. Those skilled in the art can flexibly set the specific value of the preset value based on experiments or experience in practical applications, as long as the critical point limited by the preset value can be used to determine whether the rotation speed of the inner cylinder can be directly accelerated to the centrifugal speed.

[0214] Furthermore, it should be noted that in practical applications, those skilled in the art can set the rotation speed to a fixed value, or the rotation speed can be set to vary, with the specific value determined according to the weight of the clothing, etc. Such flexible adjustments and changes do not deviate from the principles and scope of the present invention and should all be limited to the protection scope of the present invention.

[0215] Furthermore, it should be noted that in practical applications, those skilled in the art can set the time to a fixed value, or the time can be set to vary, with the specific value determined according to the weight of the clothing, etc. Such flexible adjustments and changes do not deviate from the principles and scope of the present invention and should all be limited to the protection scope of the present invention.

[0216] Preferably, the set rotation speed corresponds to the weight of the clothes. That is, the set rotation speed value is not fixed, and its specific value is determined according to the weight of the clothes in the inner drum. In particular, the set rotation speed and the weight of the clothes are positively correlated; that is, the greater the weight of the clothes, the greater the set rotation speed value.

[0217] Preferably, the set time corresponds to the weight of the clothing. That is, the set time value is not fixed, but is determined based on the weight of the clothing in the inner drum. Specifically, the set time and the weight of the clothing are positively correlated; that is, the heavier the clothing, the longer the set time value.

[0218] Preferably, the standard rotation mode of the present invention has multiple rotation speed stages, in which the inner cylinder rotates at different speeds.

[0219] When the clothes in the inner drum are not made of easily worn materials, the inner drum operates according to the standard rotation mode. Specifically, the inner drum rotates at multiple different speeds, such as two, three, or more different speeds. By rotating the inner drum at different speeds, the clothes in the inner drum are constantly changing position, allowing the clothes to come into fuller contact with the fresh air entering the inner drum, which is more conducive to preventing the clothes in the inner drum from developing odors.

[0220] It should be noted that the rotational speeds in multiple rotational speed stages can all be less than the centrifugal speed, or the rotational speed in one rotational speed stage can reach the centrifugal speed, etc. Such flexible adjustments and changes do not deviate from the principles and scope of the present invention and should all be limited to the protection scope of the present invention.

[0221] Furthermore, it should be noted that the rotational speeds in the multiple speed stages can increase sequentially, or decrease sequentially, or fluctuate up and down, etc. Such flexible adjustments and changes do not deviate from the principles and scope of the present invention and should all be limited to the protection scope of the present invention.

[0222] Preferably, the multiple rotational speed stages include one stage where the rotational speed reaches the centrifugal speed. That is, among the multiple rotational speed stages in the standard rotational mode, there is one stage where the rotational speed reaches the centrifugal speed.

[0223] For example, the standard rotation mode has four rotational speed stages executed sequentially, with the speeds of the four speed stages being speed A, speed B, speed C, and speed D, wherein one of speeds A, B, C, and D is a centrifugal speed, and the other three speeds are all less than the centrifugal speed.

[0224] Preferably, the rotational speed increases sequentially in multiple rotational speed stages.

[0225] For example, the standard rotation mode has four rotation speed stages executed sequentially, namely rotation speed A, rotation speed B, rotation speed C, and rotation speed D, wherein rotation speed A < rotation speed B < rotation speed C < rotation speed D, and rotation speed D is the centrifugal speed. Specifically, rotation speed A is 20 rpm to 45 rpm, rotation speed B is 40 rpm to 65 rpm, rotation speed C is 60 rpm to 85 rpm, and rotation speed D is the centrifugal speed, preferably greater than 90 rpm.

[0226] In the standard rotation mode, the inner cylinder's rotation speed is first accelerated to speed A, and the inner cylinder rotates at speed A for 5 to 50 seconds. Then it is accelerated to speed B, and the inner cylinder rotates at speed B for 5 to 30 seconds. Then it is accelerated to speed C, and the inner cylinder rotates at speed C for 5 to 20 seconds. Finally, it is accelerated to speed D.

[0227] Example 4

[0228] The fourth embodiment of the present invention will now be described with reference to Figures 5 to 7.

[0229] This invention also provides a control method for a washing machine. As shown in Figure 5, when it is necessary to activate the fresh air device, the control method of this invention includes the following steps: S100: acquiring information about the clothes in the inner drum; S200: acquiring a preset wind speed corresponding to the information about the clothes; S300: causing the fan to run at the preset wind speed. The information about the clothes includes at least one of the following: weight, material, and type.

[0230] In other words, when the washing machine of the present invention needs to activate the fresh air device, the fan speed needs to be determined according to the weight, material and / or type of clothes in the inner drum. The fan speed is different for clothes of different weights, materials and / or types. By matching the fan speed with the weight, material and / or type of clothes, the fresh air device can provide a more suitable air volume to the inner drum, which helps to avoid the situation where the clothes in the inner drum produce odors due to the fan speed being too low, thus ensuring the fresh air effect of the fresh air device. It also helps to avoid the situation where the fan speed is too high, which would lead to wasted energy, thus making it more energy-efficient.

[0231] It should be noted that the washing machine of the present invention can obtain any one of the following information: weight, material, and type of clothing, and then determine the fan speed based on this one piece of information. Alternatively, it can obtain any two of the following information: weight, material, and type of clothing, and then combine these two pieces of information to determine the fan speed. Or, it can obtain all three of the following information: weight, material, and type of clothing, and then combine these three pieces of information to determine the fan speed. Such flexible adjustments and changes do not deviate from the principles and scope of the present invention and should all be limited to the protection scope of the present invention.

[0232] In a first preferred embodiment, as shown in Figures 5 and 6, step S100, "obtaining information about the clothing in the inner drum," specifically includes: S110: "obtaining the material of the clothing in the inner drum"; step S200, "obtaining a preset wind speed corresponding to the clothing information," specifically includes: S210: obtaining a preset wind speed corresponding to the material of the clothing, wherein the magnitude of the preset wind speed is inversely related to the breathability of the clothing material. That is, the present invention preferably determines the fan speed based on the material of the clothing in the inner drum; specifically, the magnitude of the preset wind speed is inversely related to the breathability of the clothing material.

[0233] Specifically, different types of clothing have different breathability. The more breathable the clothing, the easier it is for fresh air to penetrate and remove moisture from the clothing. Conversely, the less breathable the clothing, the less easily fresh air can penetrate. Therefore, for clothing with good breathability, the fan can be run at a lower speed to save energy. For clothing with poor breathability, the fan needs to be run at a higher speed to effectively ensure the fresh air effect and prevent the clothing from developing odors.

[0234] Furthermore, the material of the clothing includes a first type of material, a second type of material, and a third type of material. The first type of material has greater breathability than the second type of material, and the second type of material has greater breathability than the third type of material. The preset wind speed includes a first preset wind speed, a second preset wind speed, and a third preset wind speed. The first preset wind speed is less than the second preset wind speed, and the second preset wind speed is less than the third preset wind speed.

[0235] Specifically, step S210, "obtaining the preset wind speed corresponding to the material of the clothing", includes: S211: if the material of the clothing is a first type of material, the corresponding preset wind speed is the first preset wind speed; S212: if the material of the clothing is a second type of material, the corresponding preset wind speed is the second preset wind speed; S213: if the material of the clothing is a third type of material, the corresponding preset wind speed is the third preset wind speed.

[0236] For example, the fan has three speed settings: low speed, medium speed and high speed. The fan speeds when running at low speed, medium speed and high speed are the first preset speed, the second preset speed and the third preset speed, respectively. The first type of material includes pure cotton and silk, the second type of material includes fiber materials, and the third type of material includes leather materials.

[0237] It should be noted that the material of clothing is not limited to the three categories mentioned above. For example, it can also be divided into two, four or more categories. Correspondingly, the number of preset wind speeds is not limited to the three mentioned above. The number of preset wind speeds is the same as the number of clothing material categories.

[0238] Furthermore, it should be noted that for washing machines with a fresh air function, a button to activate the fresh air function can be set on the control panel. When the user selects the fresh air function, the washing machine will automatically execute the fresh air mode after completing the washing program. If the user does not select the fresh air function, the washing machine will not execute the fresh air mode after completing the washing program. Alternatively, the washing machine can be set to automatically determine whether to execute the fresh air mode. One or more preset conditions for activating the fresh air function can be stored in the controller of the washing machine. When the preset conditions are met, the washing machine will automatically execute the fresh air mode after completing the washing program, etc. Such flexible adjustments and changes do not deviate from the principles and scope of this invention and should be limited to the protection scope of this invention.

[0239] In the second preferred embodiment, as shown in Figures 5 and 7, step S100, "obtaining information about the clothes in the inner drum," specifically includes: S120: obtaining the weight of the clothes in the inner drum; step S200, "obtaining a preset wind speed corresponding to the information about the clothes," specifically includes: S220: obtaining a preset wind speed corresponding to the weight of the clothes. The preset wind speed is positively correlated with the weight of the clothes.

[0240] In other words, when the washing machine of the present invention needs to activate the fresh air device, it needs to determine the fan speed according to the weight of the clothes in the inner drum. The fan speed is different for clothes of different weights. By matching the fan speed with the weight of the clothes, it can avoid the situation where there are too many clothes but the fan speed is too low, which is conducive to improving the fresh air effect of the fresh air mode and preventing the clothes in the inner drum from producing odors. It can also avoid the situation where there are few clothes but the fan speed is too high, which is more energy-efficient.

[0241] For example, the fan has three speed settings: low speed, medium speed and high speed. Correspondingly, three weight ranges are set for the weight of the clothing: a first weight range, a second weight range and a third weight range. The low speed corresponds to the first weight range, the medium speed corresponds to the second weight range, and the high speed corresponds to the third weight range.

[0242] It should be noted that if the fan speed is determined based on the type of clothing, the clothing can be divided into several different categories according to its thickness. For example, summer clothing (such as T-shirts and shirts) can be classified as Category 1, spring and autumn clothing (such as coats and sweatshirts) as Category 2, and winter clothing (such as sweaters and down jackets) as Category 3. The fan speed corresponding to Category 1 clothing is the lowest, the fan speed corresponding to Category 2 clothing is higher, and the fan speed corresponding to Category 3 clothing is the highest.

[0243] Preferably, as shown in Figures 6 and 7, the control method of the present invention further includes: S400: rotating the inner drum. That is, during the execution of the fresh air mode, the inner drum can also be rotated. By rotating the inner drum, the position of the clothes in the inner drum can be changed as the inner drum rotates, allowing the moisture of the clothes to be better dissipated and carried away by the fresh air, which can further improve the fresh air effect and is more conducive to preventing the clothes from producing odors.

[0244] It should be noted that, in practical applications, those skilled in the art can set it so that when the fresh air mode is executed, the inner drum is rotated directly, or, before rotating the inner drum, it can be determined whether the weight of the clothes in the inner drum is greater than a preset weight (e.g., 1 kg), and the inner drum is rotated only when the weight of the clothes in the inner drum is greater than the preset weight, etc. Such flexible adjustments and changes do not deviate from the principles and scope of the present invention, and should all be limited to the protection scope of the present invention.

[0245] Furthermore, it should be noted that when the inner cylinder needs to rotate, it can rotate at a fixed speed, or it can rotate alternately at multiple different speeds. In addition, the inner cylinder can rotate continuously in one direction, or it can rotate alternately in forward and reverse directions, or it can rotate intermittently, etc. Such flexible adjustments and changes do not deviate from the principles and scope of the present invention and should all be limited to the protection scope of the present invention.

[0246] In preferred example 1, the step of "rotating the inner drum" specifically includes: obtaining a preset rotation speed corresponding to the weight of the clothing; and rotating the inner drum at the preset rotation speed. The preset rotation speed is positively correlated with the weight of the clothing.

[0247] In other words, when the inner drum needs to rotate, the rotation speed of the inner drum corresponds to the weight of the clothes in the inner drum. By matching the rotation speed of the inner drum with the weight of the clothes in the inner drum, it is beneficial for the clothes in the inner drum to tumble smoothly with the inner drum.

[0248] For example, the first weight range is 0 to 2 kg, the second weight range is greater than 2 kg and not greater than 5 kg, and the third weight range is greater than 5 kg. The preset speed includes a first preset speed, a second preset speed, and a third preset speed. The first preset speed is less than the second preset speed, and the second preset speed is less than the third preset speed. The first preset speed corresponds to the first weight range, the second preset speed corresponds to the second weight range, and the third preset speed corresponds to the third weight range. The first preset speed is 20 rpm, the second preset speed is 40 rpm, and the third preset speed is 60 rpm.

[0249] When the weight of the clothes in the inner drum is in the first weight range, the fan runs at a low speed and the inner drum rotates at 20 rpm. When the weight of the clothes in the inner drum is in the second weight range, the fan runs at a medium speed and the inner drum rotates at 40 rpm. When the weight of the clothes in the inner drum is in the third weight range, the fan runs at a high speed and the inner drum rotates at 60 rpm.

[0250] It should be noted that the first preset speed is not limited to 20 rpm, the second preset speed is not limited to 40 rpm, and the third preset speed is not limited to 60 rpm. Those skilled in the art can flexibly set the specific values ​​of the first, second, and third preset speeds based on experiments or experience in practical applications. Preferably, the first preset speed is any value between 10 rpm and 30 rpm, the second preset speed is any value between 30 rpm and 50 rpm, and the third preset speed is any value between 50 rpm and 70 rpm.

[0251] In addition, it should be noted that during the rotation of the inner cylinder at the first preset speed, the second preset speed, or the third preset speed, the inner cylinder can be rotated continuously in the forward direction, or it can be rotated in both directions, for example, rotating in the forward direction for 60 seconds and then rotating in the reverse direction for 60 seconds, with the forward and reverse rotations alternating.

[0252] In preferred example 2, the step of "rotating the inner cylinder" specifically includes: rotating the inner cylinder at multiple different speeds alternately.

[0253] In other words, when the inner drum needs to rotate, its rotation speed is not fixed but constantly changing. By constantly changing the rotation speed of the inner drum, it is more effective to change the position of the clothes in the inner drum, causing the clothes to tumble continuously, thereby improving the fresh air effect.

[0254] For example, the rotational speeds of the inner cylinder include: A speed of 25 rpm, B speed of 45 rpm, and C speed of 55 rpm. When the inner cylinder needs to rotate, it operates in a cycle pattern of A→B→C→A→B→C, with each rotational speed lasting for 60 seconds.

[0255] It should be noted that the speed A is not limited to 25 rpm, the speed B is not limited to 35 rpm, and the speed C is not limited to 50 rpm. Those skilled in the art can flexibly set the specific values ​​of speed A, speed B, and speed C based on experiments or experience in practical applications. Among them, speed A is preferably 20 to 30 rpm, speed B is preferably 30 to 40 rpm, and speed C is preferably 40 to 60 rpm.

[0256] Furthermore, in this embodiment, the inner cylinder can be continuously rotated in the forward direction, or it can be rotated in both directions. For example, when performing the first rotation speed A → B → C, the inner cylinder is rotated in the forward direction; when performing the second rotation speed A → B → C, the inner cylinder is rotated in the reverse direction, and so on. Alternatively, the rotation direction of the inner cylinder can be changed each time the rotation speed is changed, etc. Such flexible adjustments and changes do not deviate from the principles and scope of the present invention and should be limited to the protection scope of the present invention.

[0257] In preferred example 3, the step of "rotating the inner cylinder" specifically includes: rotating the inner cylinder intermittently.

[0258] It should be noted that, in this embodiment, those skilled in the art can pre-set the rotation time and stopping time of the inner drum each time, or they can set it to determine the rotation time and stopping time of the inner drum each time based on the weight of the clothes in the inner drum, etc. Such flexible adjustments and changes do not deviate from the principles and scope of the present invention and should all be limited to the protection scope of the present invention.

[0259] Furthermore, in this embodiment, the rotation-to-stop ratio of the inner drum is positively correlated with the weight of the clothes inside. That is, the rotation-to-stop ratio of the inner drum during intermittent rotation is not fixed each time the fresh air mode is executed. It needs to be determined based on the weight of the clothes inside the drum. If the weight of the clothes is large, the rotation-to-stop ratio of the inner drum will be relatively large.

[0260] For example, taking the three weight ranges mentioned above as examples, the rotation-to-stop ratio corresponding to the first weight range is K1, the rotation-to-stop ratio corresponding to the second weight range is K2, and the rotation-to-stop ratio corresponding to the third weight range is K3, where K1 < K2 < K3. If the weight of the clothes in the inner drum is in the first weight range, the rotation-to-stop ratio of the inner drum is K1 (e.g., 1:1). If the weight of the clothes in the inner drum is in the second weight range, the rotation-to-stop ratio of the inner drum is K2 (e.g., 2:1). If the weight of the clothes in the inner drum is in the third weight range, the rotation-to-stop ratio of the inner drum is K3 (e.g., 3:1).

[0261] In preferred example 4, in this embodiment, preferred example 1 and preferred example 3 can be combined, that is, the inner drum rotates intermittently, and the rotation speed of the inner drum is determined according to the weight of the clothes in the inner drum.

[0262] In preferred example 5, in this embodiment, preferred example 2 and preferred example 3 can be combined, that is, the inner cylinder rotates intermittently, and the inner cylinder runs alternately at multiple different speeds during the rotation process.

[0263] In preferred embodiment 6, the step of "rotating the inner cylinder" specifically includes: alternating between forward and reverse rotation of the inner cylinder. In this embodiment, the inner cylinder rotates in both directions, and the rotation speed of the inner cylinder is fixed.

[0264] Preferably, after step S300, "making the fan run at a preset wind speed", the control method of the present invention further includes: S500: obtaining the humidity in the inner cylinder; S600: selectively reducing the wind speed of the fan according to the humidity in the inner cylinder.

[0265] During the initial operation of the fresh air mode, the humidity inside the drum is relatively high, which makes it easier for bacteria to grow. This causes the fan to run at a higher speed, which helps prevent clothes from developing odors. As time goes on, the humidity of the clothes will gradually decrease. When the humidity of the clothes drops to a certain level, the fan speed can be reduced, making it more energy-efficient.

[0266] For example, a preset humidity is set for the humidity in the inner drum. The specific value of the preset humidity is pre-stored in the controller of the washing machine. When the fresh air mode is executed, if the fan is running at the medium speed, when the humidity in the inner drum drops to the preset humidity, the fan will run at the low speed.

[0267] It should be noted that those skilled in the art can also set multiple different preset humidity levels in practical applications. For example, a first preset humidity and a second preset humidity can be set, where the first preset humidity is lower than the second preset humidity. When the humidity in the inner cylinder drops to the second preset humidity, the fan speed is reduced by one level. When the humidity in the inner cylinder drops to the first preset humidity, the fan speed is reduced by another level, and so on. Such flexible adjustments and changes do not deviate from the principles and scope of the present invention and should all be limited to the protection scope of the present invention.

[0268] Furthermore, it should be noted that the present invention does not limit the specific value of the preset humidity. Those skilled in the art can flexibly set the specific value of the preset humidity based on experiments or experience in practical applications.

[0269] Furthermore, it should be noted that the above-mentioned control methods are all executed by the controller of the washing machine of the present invention.

[0270] It should be noted that the control method provided in this embodiment can be stored as a program in a computer-readable storage medium. This storage medium includes several instructions to cause a computer device (which may be a personal computer, server, or network device, etc.) or processor to execute some steps of the methods in the various embodiments of the present invention. The aforementioned storage medium includes various media capable of storing program code, such as a USB flash drive, external hard drive, read-only memory (ROM), random access memory (RAM), magnetic disk, or optical disk.

[0271] Those skilled in the art will understand that although some embodiments described herein include certain features included in other embodiments but not others, combinations of features from different embodiments are intended to be within the scope of this application and form different embodiments. For example, any of the claimed embodiments in the claims of this application can be used in any combination.

[0272] The technical solution of the present invention has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will all fall within the scope of protection of the present invention.
