Description

Technical Field

[0001] The present invention belongs to the technical field of clothing processing, and in particular relates to a control method, an electronic device and a clothing processing device. Background Art

[0002] When using a washer-dryer and a clothes dryer, accurately judging whether the drying is complete has always been a goal that technicians in this field have been committed to achieving. When running the drying program, existing washer-dryers and clothes dryers usually need to obtain the temperature values ​​of different positions in the inner drum through a temperature sensing package, and judge whether the clothes in the drum are dried according to the temperature difference at different positions. The change in the water content of the clothes is judged by the temperature difference at different positions, and further judged whether the clothes are dried. However, affected by factors such as the weight of the clothes, the air volume, wind speed during drying, and the drying temperature, the temperature difference between different positions in the inner drum is very large, and the number of temperature sensing packages is limited, which cannot completely cover the entire area of ​​the inner drum, making it difficult to accurately judge whether the clothes are dried. At the same time, the above method mainly detects the temperature of the outer surface of the clothes, and cannot detect the temperature of the inner surface of the clothes, which further affects the accuracy of judging whether the clothes are dried, which is easy to cause the drying time to be too long, which is easy to damage the clothes, and also causes a waste of water and electricity resources.

In this way, by injecting an external solution with a volume within the first preset range and available for detection to obtain water quality parameters into the collection box, when the condensed water enters the collection box, since the condensed water does not carry other ions, at this time, as the condensed water increases, the water quality parameters of the mixed water formed by the external solution and the condensed water will continue to decrease. When the water quality parameters of the mixed water are stable, it means that no condensed water has entered the collection box at this time, that is, no moisture in the clothing has been evaporated and condensed with the airflow, indicating that the clothing has been dried. In this way, by judging the ion concentration of the liquid in the collection box, it is possible to more accurately judge whether the clothing has been dried in the drying program. At the same time, this control method does not need to consider the influence of factors such as the weight of the clothes, the temperature and flow rate of the drying air flow, and the moisture content of the clothes. The drying program is ended only when there is no water on the clothes that can be evaporated and condensed water is formed, further ensuring the accuracy of the judgment of whether the clothes are dried.

[0029] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

[0030] It should be understood that the "multiple" mentioned herein refers to two or more. In the description of the embodiments of the present application, unless otherwise specified, " / " means or, for example, A / B can mean A or B; "and / or" in this article is only a description of the association relationship of the associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in order to facilitate the clear description of the technical solution of the embodiments of the present application, in the embodiments of the present application, the words "first", "second" and the like are used to distinguish between the same items or similar items with basically the same functions and effects. Those skilled in the art can understand that the words "first", "second" and the like do not limit the quantity and execution order, and the words "first", "second" and the like do not limit them to be necessarily different.

[0031] In addition, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus that includes a series of steps or elements is not necessarily limited to those steps or elements explicitly listed, but may include other steps or elements not explicitly listed or inherent to such process, method, product, or apparatus.

[0032] In view of the problem that it is difficult to accurately judge whether the clothes are dried when using existing washing and drying machines and clothes dryers, the present application provides a control method, which judges whether the clothes are dried based on the condensed water generated when the clothes are dried and the ion concentration of the solution inside and outside the collection box, thereby ensuring the accuracy of the judgment on whether the clothes are dried and ensuring the user experience when using the washing and drying machine and clothes dryer.

[0033] According to a first aspect of the embodiment of the present disclosure, Figure 1 and Figure 2As shown, a control method is provided for a clothes processing device, the clothes processing device has a drying function, the clothes processing device includes an inner drum and a condensation module, the inner drum is used to accommodate clothes, the condensation module is used to condense water vapor in the airflow after drying the clothes, the condensation module also includes a collection box, the collection box is used to collect condensed water generated when condensing the water vapor, and the control method includes:

[0034] In step S100: the clothes processing device is controlled to execute the drying stage. When executing the drying stage, the clothes processing device will generate a drying airflow that is continuously heated by the heating element for drying clothes. The drying airflow after drying clothes will carry moisture. When passing through the condensation module, the moisture in the airflow exchanges heat with the condensation module and condenses to form condensed water. It should be noted that the drying stage generally has two stages, namely the starting stage and the stable stage. The two stages here are usually determined by the temperature of the airflow used for drying. The period from the beginning of the drying stage to the time when the temperature of the airflow remains stable is the starting stage of the drying stage. In the starting stage, the heating efficiency of the heating element will gradually increase until it is stable, so that the temperature of the drying airflow will gradually increase until it is stable. From the time when the temperature of the drying airflow remains stable to the end of the drying stage, it is the stable stage of the drying stage.

[0035] In step S200: before the start of the drying stage or at the beginning of the drying stage, the condensation module is controlled to perform the liquid adding stage. In the liquid adding stage, an external solution with a volume within a first preset range is injected into the collection box, and the external solution has a water quality that can be detected to obtain water quality parameters. The function of the external solution is to provide water quality parameters that can be detected in the collection box, and the water quality parameters can be used as a basis for judging whether the clothes are dried. The external solution here can be common tap water in life. While the water quality parameters of tap water can be detected, it is also easier for users to obtain and easier to add to the collection box. Taking the control method of the present application applied to a washing and drying machine as an example, the collection box can be connected to the water inlet pipe of the washing and drying machine, so that when the collection box needs to add an external solution, tap water can be directly obtained through the water inlet pipe of the washing and drying machine.

[0036] Step S300: In the drying stage, the water quality parameters of the mixed water after the external solution and the condensed water in the collection box are mixed are obtained. As described above, there are only water molecules in the condensed water. When the condensed water enters the collection box and mixes with the external solution to form mixed water, the water quality parameters in the mixed solution will continue to decrease as the condensed water increases. When the water quality parameters of the mixed water are stable, it means that there is no condensed water entering the collection box and the clothes have been dried.

[0037] In step S400: according to the water quality parameters of the mixed water, the clothes treatment device is controlled to stop the drying stage. When the water quality parameters of the mixed water are stable, it means that no condensed water has entered the collection box and the clothes have been dried. At this time, the clothes treatment device can be controlled to stop the drying process.

[0038] Through the above technical solution, when the clothing treatment device executes the drying program, the drying airflow will evaporate the moisture of the clothing. In the process of moisture evaporation, only water molecules will be evaporated. The water molecules will follow the airflow into the condensation module for heat exchange and condensation to form condensed water. Since the evaporated water molecules do not carry other ions, the formed condensed water will not carry other ions either. In this way, by injecting an external solution with a volume within the first preset range and available for detection to obtain water quality parameters into the collection box, when the condensed water enters the collection box, since the condensed water does not carry other ions, at this time, as the condensed water increases, the water quality parameters of the mixed water formed by the external solution and the condensed water will continue to decrease. When the water quality parameters of the mixed water are stable, it means that no condensed water has entered the collection box at this time, that is, no moisture in the clothing has been evaporated and condensed with the airflow, indicating that the clothing has been dried. In this way, by judging the ion concentration of the liquid in the collection box, it is possible to more accurately judge whether the clothing has been dried in the drying program. At the same time, this control method does not need to consider the influence of factors such as the weight of the clothes, the temperature and flow rate of the drying air flow, and the moisture content of the clothes. The drying program is ended only when there is no water on the clothes that can be evaporated and condensed water is formed, further ensuring the accuracy of the judgment of whether the clothes are dried.

[0039] In order to reduce the volume of the collection box to the internal space of the clothing processing device, generally speaking, the volume of the collection box is designed to be small. When drying a large amount of clothing, there is more moisture in the clothing, and the resulting condensed water is also more. The collection box can collect less condensed water. Therefore, the collection box needs to be emptied frequently to avoid condensed water overflow. At this time, when the liquid in the collection box is emptied, the external solution will also be discharged. When the collection box collects condensed water again after the liquid is emptied, there is no water quality parameter available for detection in the collection box, and it is difficult to determine whether the clothing is dried by the water quality parameters. In order to avoid the above situation, the control method of the present application can also include step S500: in the drying stage, the water level of the mixed water in the collection box is obtained, and according to the water level of the mixed water, the condensation module is controlled to perform the rehydration stage. In the rehydration stage, the mixed water is controlled to be discharged from the collection box. After the mixed water is discharged from the collection box, the external solution with a volume within the first preset range is re-injected into the collection box. In this way, when there are a lot of clothes and a lot of condensed water is generated, in order to avoid overflow of mixed water, the collection box can be emptied first, and at the same time, an external solution with a volume within the first preset range can be re-injected into the collection box. The water quality parameters of the liquid in the collection box can be re-tested, and based on the water quality parameters of the mixed water, it can be determined whether the clothes are dried.

[0040] Step S500 may include step S501: in the drying stage, the water level of the mixed water in the collection box is obtained in real time, and when the water level of the mixed water exceeds the first preset value, the condensation module is controlled to execute the rehydration stage. The first preset value here can be designed according to the actual use and size adaptability of the collection box, and the present disclosure does not make specific limitations on this. At the same time, the time for the condensation module to execute the rehydration stage can be determined according to the set first preset value. When the first preset value is larger, the time for executing the rehydration stage is also longer, ensuring that the mixed water can be discharged. When the condensation module executes the rehydration stage, the collection box can still collect condensed water at this time, and the condensed water collected during the rehydration stage is directly discharged, avoiding the condensed water from being unable to be collected during the rehydration stage.

[0041] In some embodiments, step S400 may include step S401: obtaining the fluctuation W of the water quality parameter of the mixed water in the first time period, and when the fluctuation W is less than or equal to the second preset value, controlling the clothing processing device to stop the drying stage. The second preset value here can be set to 0 or a value close to 0. Taking the second preset value being set to 0 as an example, since the fluctuation has no negative value, it is necessary to determine whether the fluctuation W is equal to 0. If the fluctuation W is equal to 0, it means that no condensed water is generated in the first time period, and no condensed water enters the mixed water, resulting in no fluctuation in the water quality parameter of the mixed water. At this time, it means that the clothes have no moisture that can be dried by the drying airflow. When the second preset value is close to 0, it means that the fluctuation of the water quality parameter is small at this time, and there is not enough condensed water to enter the mixed water. At this time, it means that the moisture in the clothes that can be dried by the drying airflow is very little, and the drying program can be stopped at this time. The clothes can rely on their own residual heat to dry the remaining very little moisture.

[0042] Step S300 may include step S301: in the drying stage, periodically obtaining water quality parameters of mixed water after the external solution in the collection box and the condensed water are mixed. Periodically obtaining the water quality parameters of the mixed water can ensure the continuity of the water quality parameter data of the mixed water, and help to capture the fluctuations in the water quality parameters of the mixed water. For example, one cycle can be 1s, that is, the water quality parameters of the mixed water are detected once every 1s, so as to achieve real-time detection of the water quality parameters. For another example, one cycle can be 5s, that is, the water quality parameters of the mixed water are detected once every 5s. The first time period mentioned above includes at least one cycle. For example, the first time period is set to 10 and one cycle is set to 2S. At this time, data of 5 water quality parameters can be obtained in the first time period. Based on the data of these 5 water quality parameters, the fluctuation W of the water quality parameters of the mixed water in the first time period is obtained.

[0043] The control method may further include step S600: after the clothes processing device stops the drying stage, controlling the condensation module to perform the drainage stage, in which the mixed water in the collection box is drained. In this way, it is ensured that there is no residual mixed water in the collection box when the drying operation is performed next time, and the problem of residual mixed water mixing with the added external solution causing liquid to overflow from the collection box is avoided.

[0044] It should be noted that water quality parameters are usually composed of multiple indicators. In this application, the detection of water quality parameters mentioned above and below refers to the detection of one or more indicators in the water quality parameters. The fluctuation of the water quality parameters mentioned above refers to the fluctuation of one or more indicators in the first time period. At the same time, when it is necessary to detect indicators in multiple water quality parameters, the second preset value can be set with multiple corresponding ones, and the second preset value can be designed according to the adaptability of the detected indicators. Specifically, the water quality parameters may include chemical water quality indicators, and the chemical water quality indicators include one or more of the hardness indicators, hydrogen ion concentration indicators, oxygen ion concentration indicators, and conductivity indicators. In some embodiments, the water quality parameter may be a calcium and magnesium ion concentration indicator in the hardness indicator. The calcium and magnesium ion concentration indicator is easier to detect. Combined with the steps in the control method mentioned above and taking the calcium and magnesium ion concentration indicator in the water quality parameter as an example, in the control method, it is necessary to detect the calcium and magnesium ion concentration in the collection box. When the fluctuation of the calcium and magnesium ion concentration is less than or equal to the second preset value, the clothing processing equipment is controlled to stop the drying program.

[0045] According to the second aspect of an embodiment of the present application, an electronic device is provided, including a memory and a processor, the memory being used to store a computer program; the processor being used to execute the computer program to implement the steps of the control method of any of the above-mentioned embodiments, and the electronic device has all the beneficial effects of the above-mentioned control method, which will not be repeated here.

[0046] According to a third aspect of an embodiment of the present application, a clothing processing device is provided, the clothing processing device having a drying function, the clothing processing device comprising an inner drum and a condensation module, the inner drum being used to accommodate clothing, the condensation module being arranged on a flow path of a drying airflow, and being used to condense water vapor in the airflow after drying the clothing, the condensation module also comprising a collection box, the collection box being used to collect condensed water generated when condensing the water vapor, the clothing processing device being used to execute the control method of any of the above-mentioned embodiments, or further comprising the above-mentioned electronic device, and having all the beneficial effects of the above-mentioned control method, which will not be repeated here.

[0047] The clothes processing device further includes a detection module, which is used to detect the water quality parameters of the liquid in the collection box and the water level of the liquid in the collection box. In this way, the condensation module can be controlled to perform the liquid replenishment phase by detecting the water level of the liquid in the collection box, and the clothes processing device can be controlled to stop the drying phase by detecting the water quality parameters of the liquid in the collection box.

[0048] The above is only a preferred implementation of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
