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

[0002] With the continuous development of laundry technology, users have put forward higher and higher requirements on the comprehensive performance of laundry devices. In particular, many users pay great attention to the cleaning efficiency of laundry devices, and in order to effectively improve the cleaning efficiency of laundry devices, the laundry device must master the weight of the clothes in the laundry device so as to specifically adjust its operating parameters according to the load. Generally, some existing laundry devices obtain the weight of the clothes by setting a weight sensor, that is, the weight of the clothes is obtained by weighing; or some laundry devices obtain the weight of the clothes by controlling the inner drum to rotate forward and backward for multiple times, that is, the weight of the clothes is indirectly calculated by the current or power of the driving motor; however, these ways of obtaining the weight are easily affected by many irrelevant factors, such as the dryness of the clothes, the water storage amount in the laundry device and the like, which will affect the accuracy of the results. In recent years, in order to effectively improve the accuracy of the measurement results, some existing laundry devices have begun to use RFID tags on the clothes to determine the weight of the clothes. Although this way of obtaining the weight can effectively avoid the influence of many irrelevant factors, since the weight information stored in the RFID tag is always the initial weight information of the clothes, it does not make corresponding adjustments according to the actual condition of the clothes, so the measurement result is still not accurate enough.

Such changes related to the specific type of laundry equipment do not deviate from the basic principles of the present application and are within the protection scope of the present application.

Those skilled in the art can understand the specific meaning of the above-mentioned term in the present application according to the specific circumstances. Although the steps of the control method of the present application are described in a specific order in the present application, these orders are not limited, and those skilled in the art can perform the steps in different orders without deviating from the basic principles of the present application.

[0025] Specifically, in the preferred embodiments, the laundry equipment includes an outer drum for storing water and an inner drum rotatably arranged in the outer drum, the inner drum can rotate relative to the outer drum to realize washing, of course, the present application does not make any limitation on the specific structure of the laundry equipment, and those skilled in the art can set it according to the actual use requirements. Further, the laundry equipment further includes an RFID reader-writer and a controller capable of being communicatively connected therewith, the RFID reader-writer is arranged in the laundry equipment, capable of reading the information in the RFID tag on the laundry in the laundry equipment, and also capable of writing new information in the RFID tag, for example, writing the corresponding washing frequency information according to the washing frequency of the laundry, the controller can acquire the information read by the RFID reader-writer, and determine the current actual weight of the laundry according to the acquired information, so as to further determine the operating parameters of the laundry equipment.

[0026] It should be noted that the present application does not make any limitation on the specific structure and specific model of the RFID reader and the controller, and the skilled person can set them according to the actual use requirements, as long as the RFID reader can read the information in the RFID tag on the clothes in the washing equipment and also can write new information in the RFID tag, and the controller can obtain the information read by the RFID reader. In addition, the RFID reader can be the original component of the washing equipment, or an external component set for the control method of the present application, and the controller can be the original controller of the washing equipment, or a controller separately set for the control method of the present application. These changes do not deviate from the basic principles of the present application and belong to the protection scope of the present application.

[0027] Firstly refer to Figure 1 , which is the main step flow chart of the control method of the present application. As Figure 1 shown, based on the washing equipment described in the above preferred embodiment, the control method of the present application mainly includes the following steps:

[0028] S1: In the case that clothes are put into the washing equipment, the initial weight information and the washing frequency information in the RFID tag on the clothes are extracted;

[0029] S2: According to the extracted initial weight information and washing frequency information, the current actual weight of the clothes is determined;

[0030] S3: According to the determined current actual weight of the clothes, the operating parameters of the washing equipment are determined.

[0031] Specifically, in step S1, in the case that clothes are put into the washing equipment, the RFID reader can extract the initial weight information and the washing frequency information in the RFID tag on the clothes. As a preferred embodiment, the RFID reader can write new washing frequency information in the RFID tag on the corresponding clothes after each time of washing clothes, so as to update the washing frequency information in the RFID tag in time, but this is not restrictive, and the skilled person can update the washing frequency information in the RFID tag by other ways. In addition, it should be noted that the present application does not make any limitation on the type of information contained in the RFID tag on the clothes, and the skilled person can set it according to the actual use requirements.

[0032] Then, in step S2, the controller can determine the current actual weight of the clothes according to the initial weight information and the washing frequency information extracted by the RFID reader-writer. Specifically, when the user only puts one piece of clothes into the washing device, the controller directly determines the current actual weight of the clothes according to the initial weight information and the washing frequency information of the clothes; when the user puts multiple pieces of clothes into the washing device, the controller can determine the current actual weight of each piece of clothes according to the initial weight information and the washing frequency information of each piece of clothes extracted by the RFID reader-writer, and then adds the current actual weights of all the clothes to obtain the current actual weight of all the clothes.

[0033] It should be noted that the present application does not limit the specific way of determining the current actual weight of the clothes according to the initial weight information and the washing frequency information, and the skilled person can set it according to the actual use requirement, as long as the initial weight information and the washing frequency information are involved in the process of determining the current actual weight of the clothes, which belongs to the protection scope of the present application.

[0034] Finally, in step S3, the controller can determine the operating parameter of the washing device according to the current actual weight of the clothes determined in step S2. It should be noted that the present application does not limit the specific determination method, and the skilled person can set it according to the actual use requirement, and the adjustment of this determination method does not deviate from the basic principle of the present application; and the present application also does not limit the specific type of the operating parameter, and the skilled person can select it according to the actual use requirement, for example, the operating parameter can be the water amount of the washing device, the detergent amount of the washing device, or even the cleaning time of the washing device, etc.

[0035] Next, refer to Figure 2 , which is a step flow chart of the preferred embodiment of the control method of the present application. As Figure 2 shown, based on the washing device described in the above preferred embodiment, the preferred embodiment of the control method of the present application specifically includes the following steps:

[0036] S101: In the case where different materials of clothes are put into the washing device, the initial weight information and the washing frequency information in the RFID tag on each piece of clothes are extracted respectively;

[0037] S102: Further, the material information in the RFID tag on each piece of clothes is extracted respectively;

[0038] S103: The corresponding weight correction coefficient of each piece of clothes is determined according to the washing frequency information and the material information of each piece of clothes extracted respectively;

[0039] S104: calculate the actual weight of each piece of clothing currently;

[0040] S105: based on the calculated actual weight of each piece of clothing currently, calculate the actual weight of all clothes of each material currently;

[0041] S106: according to the material information of all clothes and the calculated actual weight of all clothes of each material currently, determine the water amount and detergent amount of the washing equipment.

[0042] In step S101, in the case where different materials of clothes are put into the washing equipment, the RFID reader can extract the initial weight information and the washing frequency information in the RFID tag on each piece of clothing. It should be noted that the present application does not make any restrictions on the type of information contained in the RFID tag on the clothes, and the skilled person can set it according to the actual use requirement. In step S102, the RFID reader can further extract the material information in the RFID tag on each piece of clothing, i.e. the RFID tag on the clothes contains the initial weight information, washing frequency information and material information of the clothes. It can be understood that the present application does not make any restrictions on the timing of obtaining the initial weight information, washing frequency information and material information, and the skilled person can set it according to the actual use requirement; for example, it can be obtained simultaneously or sequentially in order. This change of parameter acquisition sequence does not deviate from the basic principle of the present application and belongs to the protection scope of the present application.

[0043] Further, in order to effectively ensure the accuracy of the acquisition result, in one preferred embodiment, step S101 specifically comprises: first extracting the initial weight information and the washing frequency information in the RFID tag on the clothes; then rotating the inner drum of the washing equipment by a predetermined number of turns; again extracting the initial weight information and the washing frequency information in the RFID tag on the clothes; if the amount of information extracted twice is the same, stop extracting; if the amount of information extracted twice is different, rotate the inner drum of the washing equipment by the predetermined number of turns each time and then extract again until the amount of information extracted twice is the same. Based on this, the present application can effectively avoid the problem that the RFID tag of part of the clothes is covered and not acquired by means of twice acquisition, so as to effectively ensure that the RFID tag of all clothes in the washing equipment can be acquired, and further effectively ensure the accuracy of the calculation result. Preferably, the predetermined number of turns is two, so as to make the clothes at the bottom turn to the upper part as much as possible, thereby effectively improving the accuracy of the acquisition result.

[0044] Based on the extraction results of step S101 and step S102, in step S103, the controller can determine the corresponding weight correction coefficient of each piece of clothing according to the washing frequency information and material information extracted. Specifically, for each piece of clothing, the controller can determine the corresponding weight correction coefficient according to the washing frequency information and material information in its RFID tag; as a preferred determination method, the washing frequency information and the material information and the weight correction coefficient satisfy a certain correspondence relationship, which can be determined through multiple tests. In this case, the one-to-one correspondence relationship between the washing frequency information and the weight correction coefficient can be determined according to the material information, that is, the specific relationship between the washing frequency information and the weight correction coefficient is different when the material information is different, and the unique weight correction coefficient can be determined according to the material information and the washing frequency information. Of course, this is only a preferred determination method, and the skilled person can obviously adopt other methods according to actual use requirements.

[0045] Then, in step S104, based on the weight correction coefficient determined in step S103, the controller calculates the current actual weight of each piece of clothing by the following formula:

[0046] W 当前 = k x W 初始

[0047] Wherein, W 当前 is the current actual weight of the clothing, k is the corresponding weight correction coefficient of the clothing, and W 初始 is the initial weight of the clothing.

[0048] Based on the above calculation results, the current actual weight of each piece of clothing can be determined, and in step S105, the controller can calculate the current actual weight of all clothes corresponding to each material based on the above calculation results. For example, if there are two pieces of cotton clothing, the current actual weight of the two pieces of cotton clothing is added to obtain the current actual weight of all clothes corresponding to cotton, and the calculation method of the current actual weight of all clothes corresponding to other materials can be similarly applied.

[0049] Further, in step S106, the controller can determine the water inflow amount and the detergent amount of the washing device according to the material information of all the clothes and the actual weight of all the clothes of each material. The water absorption amount and the cleaning difficulty of each material are different, for example, the water inflow amount and the detergent amount required for cleaning cotton clothes are certainly larger. Based on this, the controller accurately determines the water inflow amount and the detergent amount of the washing device according to the material information of all the clothes and the actual weight of the clothes of each material, so as to strictly formulate the corresponding water inflow amount and detergent amount according to the different clothes put in the washing device, thereby maximizing the cleaning efficiency and saving the cleaning cost. In addition, it also needs to be explained that the application does not make any limitation on the above specific corresponding relationship, and the technical personnel can set it according to the actual use demand and the specific type of the washing device.

[0050] In addition, it also needs to be explained that although the operation parameters in the preferred embodiment include the water inflow amount and the detergent amount of the washing device; however, the operation parameters can obviously only include the water inflow amount of the washing device, or only include the detergent amount of the washing device, of course, other operation parameters of the washing device, such as the cleaning time, etc., are not limited, and the technical personnel can adjust it according to the actual use demand.

[0051] In addition, in a feasible embodiment, the controller can determine the actual weight of the clothes according to the extracted initial weight information and the washing frequency information. Specifically, taking the determination of the actual weight of a piece of clothes as an example, the controller can first determine the weight correction coefficient corresponding to the clothes according to the washing frequency information in the RFID tag on the clothes, and then calculate the actual weight of the clothes by the following formula:

[0052] W 当前 = k x W 初始

[0053] Wherein, W 当前 is the actual weight of the clothes, k is the weight correction coefficient corresponding to the clothes, and W 初始 is the initial weight of the clothes.

[0054] Based on the calculation result, the actual weight of the clothes can be determined. When the clothes are multiple, the actual weight of each clothes is determined by the above method, and the actual weight of all clothes is obtained by adding the actual weight of each clothes. Based on the actual weight of all clothes determined by the above method, the controller can determine the operation parameters of the washing equipment. In this embodiment, the controller only needs to use the initial weight information and the washing frequency information in the RFID tag on the clothes to determine the actual weight of the clothes, and then determine the operation parameters of the washing equipment.

[0055] It should be noted that the present application does not limit the specific method of determining the weight correction coefficient according to the washing frequency information, and the skilled person can set it according to the actual use requirement. As a preferred determination method, the washing frequency information and the weight correction coefficient satisfy a monotonically decreasing exponential function relationship, that is, the value of the weight correction coefficient gradually decreases with the increase of the washing frequency, and the decay rate gradually decreases, so as to better fit the actual change process of the weight change of the clothes. Of course, this is only a preferred determination method, and the skilled person can obviously use other methods according to the actual use requirement, for example, the skilled person can also determine the one-to-one mapping relationship between the washing frequency information and the weight correction coefficient through multiple tests. These changes do not deviate from the basic principles of the present application and belong to the protection scope of the present application.

[0056] In another embodiment, the controller can further extract the material information in the RFID tag on each clothes through the RFID reader and writer, and determine the corresponding weight correction coefficient according to the extracted washing frequency information and material information, so as to make the weight correction coefficient more accurate and improve the accuracy of the final result. In this embodiment, the controller needs to use the initial weight information, the washing frequency information and the material information in the RFID tag on the clothes to determine the actual weight of the clothes, and then determine the operation parameters of the washing equipment.

[0057] It should be noted that the present application does not limit the specific method of determining the weight correction coefficient according to the washing frequency information and the material information, and the skilled person can set it according to the actual use requirement. As a preferred determination method, the washing frequency information and the material information satisfy a certain corresponding relationship with the weight correction coefficient, and the corresponding relationship can be determined by multiple tests. In this case, the unique weight correction coefficient can be determined by the washing frequency information and the material information. Of course, this is only a preferred determination method, and the skilled person can obviously use other methods according to the actual use requirement.

[0058] In addition, the control method of the present application further comprises: extracting material information and type information in the RFID tag on the clothes; determining the washing program of the washing device according to the extracted material information and type information. Specifically, the controller extracts the material information and type information in the RFID tag on the clothes through the RFID reader-writer, and determines the washing program of the washing device according to the extracted material information and type information; for example, the material information in the RFID tag on the clothes is cotton, and the type information is a cotton cover, then the washing program of the washing device can be determined as strong cotton washing; for another example, the material information in the RFID tag on the clothes is cotton, and the type information is a short sleeve, then the washing program of the washing device can be determined as fast washing. At the same time, when the clothes put in are multiple, and the washing programs determined according to the material information and type information in the RFID tag on each piece of clothes are quite different, the washing device can also send a reminder to the user. It should be noted that the present application does not make any limitation on the specific corresponding relationship, and the technical personnel can set it according to the actual use demand, and the washing device can also run directly according to the washing program selected by the user, which is not limited.

[0059] So far, the technical solutions of the present application have been described in combination with the preferred embodiments shown in the drawings, but those skilled in the art can easily understand that the protection scope of the present application is obviously not limited to these specific embodiments. Those skilled in the art can make equivalent changes or replacements to the related technical features without departing from the principles of the present application, and the technical solutions after the changes or replacements will fall within the protection scope of the present application.
