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 striving to achieve. 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 sensor, and judge whether the clothes in the drum are dried according to the temperature difference at different positions. The temperature difference at different positions is used to judge the change in the water content of the clothes, and further judge whether the clothes are dried. However, due to factors such as the weight of the clothes, the air volume and 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 sensors 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. It 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. Summary of the Invention

[0017] Optionally, the method further includes:

[0020] According to a second aspect of an embodiment of the present application, an electronic device is provided, comprising a memory and a processor, wherein the memory is used to store a computer program; and the processor is used to execute the computer program to implement the steps of any one of the control methods described above.

[0021] According to a third aspect of an embodiment of the present application, a clothing processing device is provided, which has a drying function.

During the evaporation process, only water molecules are evaporated. The water molecules 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 also does not carry other ions. Thus, by injecting an external solution having a volume within a first preset range and capable of being detected 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, the water quality parameters of the mixed water formed by the external solution and the condensed water will continuously decrease as the condensed water increases. When the water quality parameters of the mixed water stabilize, it indicates that no condensed water has entered the collection box, that is, no moisture in the clothing has evaporated and condensed with the airflow, indicating that the clothing has been dried. In this way, by determining the ion concentration of the liquid in the collection box, it is possible to more accurately determine whether the clothing has been dried in the drying cycle. 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 process is ended only when no water on the clothes 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 present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0030] It should be understood that the "plurality" 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 merely a description of the association relationship of 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 a clear description of the technical solutions of the embodiments of the present application, in the embodiments of the present application, words such as "first" and "second" are used to distinguish between identical or similar items with substantially the same functions and effects. Those skilled in the art will understand that words such as "first" and "second" do not limit the quantity and execution order, and words such as "first" and "second" do not necessarily limit them to be different.

[0031] In addition, the terms "comprises" and "having" and any variations thereof are intended to cover a non-exclusive inclusion. 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 expressly listed but may include other steps or elements not expressly listed or inherent to such process, method, product or apparatus.

[0032] In response to the problem that it is difficult to accurately determine whether the clothes are dried when existing washing and drying machines and dryers are in use, the present application provides a control method, which determines 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 of using the washing and drying machine and dryer.

[0033] According to the 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 having a drying function. The clothes processing device includes an inner drum and a condensing module. The inner drum is used to accommodate clothes. The condensing module is used to condense water vapor in the air flow after drying the clothes. The condensing module also includes a collection box. The collection box is used to collect condensed water generated during the condensation of the water vapor. The control method includes:

[0034] In step S100, the clothing treatment device is controlled to execute a drying phase. During the drying phase, the clothing treatment device generates a drying airflow that is continuously heated by the heating element and used to dry the clothing. The drying airflow after drying the clothing carries moisture. When passing through the condensing module, the moisture in the airflow exchanges heat with the condensing module and condenses, forming condensed water. It should be noted that the drying phase generally has two stages: a start phase and a stable phase. These two stages are generally determined by the temperature of the drying airflow. The start phase of the drying phase is the period from the start of the drying phase until the temperature of the airflow remains stable. During the start phase, the heating efficiency of the heating element gradually increases until it stabilizes, and the temperature of the drying airflow gradually increases until it stabilizes. The stable phase of the drying phase is the period from when the temperature of the drying airflow remains stable until the end of the drying phase.

[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 tested to obtain water quality parameters. The function of the external solution is to provide water quality parameters that can be tested 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 tap water commonly seen 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: During the drying phase, the water quality parameters of the mixed water formed by the external solution and condensed water in the collection box are obtained. As described above, condensed water consists solely of water molecules. As condensed water enters the collection box and mixes with the external solution to form the mixed water, the water quality parameters of the mixed solution decrease as the amount of condensed water increases. When the water quality parameters of the mixed water stabilize, this indicates that no condensed water has entered the collection box and the clothes have been dried.

[0037] In step S400, the clothes treatment apparatus is controlled to stop the drying process according to the water quality parameters of the mixed water. 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 apparatus can be controlled to stop the drying process.

[0038] According to the above technical solution, when the clothing treatment device executes a drying cycle, the drying airflow evaporates moisture from the clothing. During the evaporation process, only water molecules are evaporated. The water molecules 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 also does not carry other ions. Thus, by injecting an external solution having a volume within a first preset range and capable of being detected 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, the water quality parameters of the mixed water formed by the external solution and the condensed water will continuously decrease as the condensed water increases. When the water quality parameters of the mixed water stabilize, it indicates that no condensed water has entered the collection box, that is, no moisture in the clothing has evaporated and condensed with the airflow, indicating that the clothing has been dried. In this way, by determining the ion concentration of the liquid in the collection box, it is possible to more accurately determine whether the clothing has been dried in the drying cycle. 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 process is ended only when no water on the clothes 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 internal space occupied by the collection box, the collection box is generally designed to be smaller. When drying a large amount of clothes, the clothes contain more moisture, and the resulting condensed water is also more. The collection box can collect less condensed water, so it is necessary to frequently empty the collection box to prevent condensed water from overflowing. In this case, when the liquid in the collection box is emptied, the external solution is also discharged. When the collection box collects the condensed water again after the liquid is emptied, there are no water quality parameters available for detection in the collection box, making it difficult to determine whether the clothes are dried based on the water quality parameters. To avoid the above situation, the control method of the present application may 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 execute 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 a 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 the water quality parameters of the mixed water can be used to determine 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 a fluctuation W of a water quality parameter of the mixed water within a first time period, and when the fluctuation W is less than or equal to a second preset value, controlling the clothing treatment device to stop the drying phase. 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 indicates that no condensed water was generated during the first time period, and no condensed water entered the mixed water, resulting in no fluctuation in the water quality parameter of the mixed water. This indicates that the clothes have no moisture that can be dried by the drying airflow. When the second preset value is close to 0, it indicates that the fluctuation of the water quality parameter is small, and not enough condensed water can enter the mixed water. This indicates that the moisture in the clothes that can be dried by the drying airflow is very low. At this time, the drying process can be stopped, and the clothes can rely on their own residual heat to dry the remaining moisture.

[0042] Step S300 may include step S301: in the drying stage, periodically obtaining the water quality parameters of the 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 laundry processing device stops the drying phase, controlling the condensing module to execute a drain phase, wherein the mixed water in the collection box is drained during the drain phase. This ensures that no mixed water remains in the collection box during the next drying operation, thereby preventing the residual mixed water from mixing with the added external solution and causing the liquid to overflow from the collection box.

[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 to correspond to multiple ones and 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 parameters may be the calcium and magnesium ion concentration indicators in the hardness indicators. The calcium and magnesium ion concentration indicators are easier to detect. In combination with the steps in the control method mentioned above and taking the detection of the calcium and magnesium ion concentration indicators in the water quality parameters as an example, in the control method, it is necessary to detect the calcium and magnesium ion concentrations in the collection box. When the fluctuation of the calcium and magnesium ion concentrations 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, comprising a memory and a processor, wherein the memory is used to store a computer program; the processor is used to execute the computer program to implement the steps of the control method of any of the above-mentioned embodiments. The electronic device has all the beneficial effects of the above-mentioned control method, which will not be repeated here.

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

[0047] The laundry processing device also includes a detection module for detecting water quality parameters and the water level of the liquid in the collection box. Thus, by detecting the water level in the collection box, the condensing module can be controlled to execute the rehydration phase, and the laundry processing device can also 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 embodiment 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.
