[0029] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings, in which:

[0030] Figure 1 is a flow chart of the main steps of the control method of the clothes processing device of the present invention;

[0031] Figure 2 It is a flowchart of the specific steps of the control method of the clothes processing device of the present invention. DETAILED DESCRIPTION

[0032] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. Those skilled in the art may make adjustments as needed to adapt to specific applications. For example, although the present application is described in conjunction with a washing machine, this is not restrictive, and the control method of the clothing processing device of the present invention can obviously also be applied to other equipment for clothing processing, for example, the clothing processing device can also be a sock washing machine, a shoe washing machine, a clothing care machine, etc.

[0033] Furthermore, the terms “first” and “second” are used for descriptive purposes only and should not be understood as indicating or implying relative importance.

[0034] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the term "connected" should be understood in a broad sense, for example, two elements can be directly connected internally, or indirectly connected through an intermediate medium. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] In order to solve the problem that existing washing machines are easily damaged when drying clothes made of special materials such as wool or silk, the present invention provides a control method for a clothing processing device, wherein the clothing processing device is configured to deliver low-temperature outside air to the clothing processing drum. Specifically, the clothing processing device includes a first air duct, one end of the first air duct is connected to the outside of the clothing processing device, and the other end of the first air duct is connected to the inside of the clothing processing drum. A fan is provided in the first air duct, so that the outside air can be delivered to the clothing processing drum after the fan is turned on. However, it should be noted that the clothing processing device may not be provided with the first air duct, but directly delivers air to the clothing processing drum through the fan. Those skilled in the art can set the structure of the clothing processing device according to their needs. The present invention does not impose any restrictions on the specific structure of the clothing processing device, as long as the clothing processing device can deliver outside air to the clothing processing drum.

[0036] Specifically, Figure 1 As shown, the control method of the clothes processing device mainly includes the following steps:

[0037] Step S100: obtaining the material of the clothing;

[0038] Step S200: Selectively operate the low-temperature dehumidification mode according to the material of the clothes.

[0039] Among them, the low-temperature dehumidification mode includes turning on the fan, and delivering low-temperature air from the outside world to the clothes treatment drum through the first air duct. Therefore, when the clothes are made of materials that require special care, such as silk, wool and other materials that require special care, the clothes can be directly dried by the low-temperature air in nature without heating the air. This can protect the clothes from damage and improve the care effect of the clothes, and can also save electricity. At the same time, the external air can also blow the lint and other debris on the clothes out of the clothes treatment drum, and the water vapor is also directly blown out of the clothes treatment drum. There is no need to set up a condenser to condense the circulating water vapor, which greatly reduces the cost of the drying care module and the cost of the whole machine. In addition, when the user does not take out the clothes for drying for a long time after washing, it may cause the clothes to mold or breed bacteria. By delivering fresh air to the clothes treatment drum, the above problems can be prevented and the user experience can be improved.

[0040] The material of the clothes can be obtained by installing a sensor in the clothes processing drum to detect the clothes, or the clothing material data can be pre-stored in the clothing processing device, and the user can set the clothing material through buttons or terminals such as mobile phone APP when using it. Therefore, the present invention does not impose any restrictions on the method of obtaining the clothing material. Technical personnel in this field can set it by themselves according to their needs, and it should all fall within the scope of protection of the present invention.

[0041] like Figure 2 As shown, a possible implementation of the control method of the washing machine of the present invention is introduced below.

[0042] Specifically, the control method includes the following steps:

[0043] Step S301: receiving an instruction for the washing machine to run a conventional laundry processing program;

[0044] Step S302: Control the washing machine to run a washing program;

[0045] Step S303: Control the washing machine to run a dehydration program;

[0046] Step S304: Obtain the weight of the clothes after dehydration;

[0047] Step S305: When the laundry weight is greater than the first preset weight, the fresh air mode is directly operated.

[0048] The washing machine weighs the clothes after washing and dehydrating. If the weight of the wet clothes exceeds the first preset weight, it means that there are too many clothes and exceeds the threshold of the weight of the clothes that can be handled by the low-temperature dehumidification mode. Therefore, the user can take out all the clothes for natural drying or low-temperature dehumidification in batches, or other drying methods can be adopted. In order to prevent the clothes from staying in the clothing processing drum for a long time and causing bacteria to grow, a small amount of external fresh air is delivered to the inner drum by running the fresh air mode to reduce bacterial growth or mold.

[0049] Step S306: when the weight of the clothing is less than or equal to the first preset weight, obtaining the material of the clothing;

[0050] Step S307: When the clothing material is a special care material, the low temperature dehumidification mode is operated for a preset time;

[0051] Step S308: When the material of the clothing is a regular care material, the fresh air mode is operated for a preset time;

[0052] Step S309: After the user takes out all the clothes, the low-temperature dehumidification mode is run for a preset time.

[0053] The user can send a washing machine operation program instruction by pressing a washing machine button or through a terminal device such as a mobile phone APP. The washing program of the washing machine is specifically to fill water into the clothing treatment drum, and then control the clothing treatment drum to rotate with preset parameters to wash the clothes. The dehydration program is specifically to dehydrate the clothes and reduce the humidity by rotating the clothing treatment drum. However, those skilled in the art can set the washing program and the dehydration program as needed, and the present invention does not impose any restrictions on this, and they should all fall within the scope of protection of the present invention.

[0054] Next, if the weight of wet clothes is less than or equal to the first preset weight, it means that the clothes are less and do not exceed the threshold value of the weight that the low-temperature dehumidification mode can handle. Then, the material of the clothes is obtained. If the material of the clothes is a special care material, the low-temperature dehumidification mode is run. If the material of the clothes is a regular care material, such as cotton, polyester, acrylic, etc., the user can take out the clothes to dry or take other drying methods to dry them. In order to avoid the clothes from being retained in the clothes processing drum for a long time and causing bacteria to grow, a small amount of external fresh air is transported to the inner drum by running the fresh air mode to reduce bacterial growth or mold. In addition, when the user takes out all the clothes, the low-temperature dehumidification mode is continued to run for a period of time, so that the clothes processing drum and the water tank can be dried to prevent the washing machine from being moldy due to long-term non-use. Of course, the special care material and the regular care material can be set by the technicians in this field as needed. The present invention does not impose any restrictions on the specific types of special care materials and regular care materials, and they should all be limited within the scope of protection of the present invention.

[0055] Low temperature dehumidification mode specifically includes:

[0056] Steps: Control the fan to start;

[0057] Step: controlling the air outlet speed to be a first preset wind speed, and the clothes processing drum to rotate at a first preset speed;

[0058] The fresh air mode specifically includes:

[0059] Steps: Control the fan to start;

[0060] Step: controlling the wind speed to be a second preset wind speed, the clothes processing drum rotates at a second preset speed, the first preset wind speed is greater than the second preset wind speed, and the first preset speed is greater than the second preset speed.

[0061] Since the fresh air mode mainly delivers fresh air into the drum to prevent bacteria from growing on clothes, and the low-temperature dehumidification mode requires drying clothes, in order to save electricity, the wind speed of the fresh air mode is lower than that of the low-temperature dehumidification mode, and the speed of the clothes processing drum in the fresh air mode is also lower than that of the clothes processing drum in the low-temperature dehumidification mode, or the speed of the clothes processing drum in the fresh air mode can also be zero, that is, it is stationary, so as to further save energy consumption. However, it should be noted that those skilled in the art can set the specific parameters of the fresh air mode and the low-temperature dehumidification mode as needed, and the present invention does not impose any restrictions on this.

[0062] In another possible implementation, the control method further includes:

[0063] Step S401: receiving an instruction for the washing machine to run a special laundry treatment program;

[0064] Step S402: Control the washing machine to run a washing program;

[0065] Step S403: Control the washing machine to run a dehydration program;

[0066] Step S404: Obtain the weight of the clothes after dehydration;

[0067] Step S405: when the weight of the clothes is greater than the first preset weight, the fresh air mode is operated;

[0068] Step S406: When the weight of the clothes is less than or equal to the first preset weight, the low-temperature dehumidification mode is operated.

[0069] When using the washing machine, the user directly chooses to run a special clothing treatment program. When the washing machine directly starts to run the special clothing treatment program, there is no need to detect the clothing material, but the clothing material is assumed to be a special care material. The washing program and dehydration program in the special clothing treatment program can be the same as or different from the conventional clothing treatment program. For example, compared with the conventional clothing treatment program, the rotation speed of the clothing treatment drum in the special clothing treatment program is slower during washing and dehydration, thereby causing less damage to the clothing during washing and dehydration. When the weight of the wet clothing does not exceed the threshold, the low-temperature dehumidification mode is directly run to improve the clothing care effect and reduce clothing damage. Of course, the weight of the clothing can be directly run in the low-temperature dehumidification mode after dehydration without detecting the weight of the clothing. Those skilled in the art can choose according to their needs, and all fall within the protection scope of the present invention.

[0070] In addition, the method for obtaining the weight of the clothes may be to set a sensor on the clothes processing drum and obtain the weight of the clothes by measuring the electrical signal of the sensor, or to obtain the weight of the clothes by a weighing device. However, it should be noted that the method for obtaining the weight of the clothes can be set by those skilled in the art according to their needs. The present invention does not impose any restrictions on the method for obtaining the weight of the clothes. As long as the weight of the clothes can be accurately obtained, it should fall within the scope of protection of the present invention.

[0071] In another possible embodiment, the washing machine is further configured to be able to input hot and dry air into the laundry processing drum. Specifically, the washing machine further includes a second air duct, a heater is provided in the second air duct, and the second air duct is connected to the laundry processing drum, so that the washing machine has a high-temperature dehumidification mode, and the high-temperature dehumidification mode specifically includes: turning on the heater, and controlling the laundry processing drum to rotate at a preset speed, but the specific steps of the high-temperature dehumidification mode can be set by those skilled in the art according to their needs, and the present invention does not impose any restrictions on this, as long as the high-temperature dehumidification mode can deliver hot and dry air to the laundry processing drum.

[0072] The control method also includes:

[0073] Steps: After the clothes are dehydrated, if the clothes are made of regular care material, or the clothes are made of special care material and the clothes weight is greater than the first preset weight, the high temperature dehumidification mode is operated;

[0074] Steps: Get clothing humidity;

[0075] Step: When the humidity of the clothes is less than or equal to the first preset humidity, the high temperature dehumidification mode is turned off and the low temperature dehumidification mode is operated;

[0076] Steps: When the clothing humidity is ≤ the second preset humidity, turn off the low-temperature dehumidification mode and run the fresh air mode.

[0077] The second preset humidity is lower than the first preset humidity.

[0078] When the user is eager to wear clothes, the high-temperature dehumidification mode can be used to speed up the drying speed of clothes. Specifically, when the material of the clothes is a regular care material, the requirement for the drying temperature is not high, and the high-temperature dehumidification function can be used for dehumidification, that is, the heater is turned on, and the clothes are dried by inputting hot and dry air into the clothes processing drum, so as to improve the drying efficiency of the clothes. When the humidity of the clothes in the clothes processing drum is reduced to below the first preset humidity, it means that the clothes are in a semi-wet and semi-dry state. At this time, if the high-temperature dehumidification is continued, the damage to the clothes is greater. Therefore, the high-temperature dehumidification mode is turned off and the low-temperature dehumidification mode is operated, that is, the low-temperature air from the outside is input into the clothes processing drum. The low-temperature air can dry the clothes without damage. Since the low-temperature dehumidification mode does not need to heat the air, it can save electricity. After a period of low-temperature dehumidification, when the clothes reach the target dryness, that is, when the humidity of the clothes is lower than the second preset humidity, the low-temperature dehumidification mode is turned off and the fresh air mode is operated, so as to prevent the problem that the user forgets to take out the clothes and stays in the clothes processing drum for a long time to breed bacteria.

[0079] In addition, when the material of the clothes is special care material and the weight of the clothes is greater than the first preset weight, the high-temperature dehumidification mode can also be operated. Since there are a lot of clothes, the dry hot air will quickly evaporate the moisture on the clothes during the early high-temperature dehumidification, so that the temperature of the clothes will rise slowly, thereby improving the drying efficiency of the clothes while causing less damage to the clothes. However, as the humidity of the clothes decreases, the temperature of the clothes gradually increases. Therefore, when there are a lot of clothes, the high-temperature dehumidification mode is operated when the humidity of the clothes is high in the early stage. After the humidity of the clothes is reduced a little, the low-temperature dehumidification mode is operated to dry the clothes at a low temperature. The fresh air mode is operated after the humidity of the clothes reaches the target humidity. The combination of high-temperature dehumidification and low-temperature dehumidification can achieve the maximum drying efficiency with minimal damage and minimal energy consumption when the user is eager to wear clothes.

[0080] In summary, the present invention obtains the material of the clothes, and when the material of the clothes is a special care material, runs the low-temperature dehumidification mode to dry the clothes, thereby saving electric energy and avoiding damage to the clothes caused by high temperature. Furthermore, when the clothes are made of conventional care materials or there are a lot of clothes, they can be dried in the high-temperature dehumidification mode when the humidity is high in the early stage, and in the low-temperature dehumidification mode when the humidity is low in the later stage, thereby improving the drying efficiency and preventing damage to the clothes and reducing energy consumption. In addition, the present invention can also prevent the clothes from being retained in the clothes processing drum for a long time and breeding bacteria through the fresh air mode, and the user can also take out the clothes after the washing machine has finished processing the clothes, and dehumidify the clothes processing drum at low temperature for a period of time, so that the inside can be dried quickly to prevent the occurrence of odor and mold, etc., and improve the user's experience.
