[0002] With the improvement of living standards, the development of the washing machine industry has also shown a diversified trend. People have more and more demands for washing machines with zoned washing and care, healthy sterilization, and multiple washing and care functions. Based on single-drum washing machines, various washing machine manufacturers have developed double-drum, triple-drum and other multi-drum washing machines to meet market demand. Among them, double-drum washing machines can already meet various needs of users in a wide range.

[0003] However, in the use of the existing twin-drum washing machine, when one of the clothes processing drums is executing the drying program, the other clothes processing drum needs to wait; or, when one of the clothes processing drums is executing the drying program, the other clothes processing drum also needs to execute the drying program, which will cause the temperature in the clothes processing drum that is executing the drying program to change and require re-drying, resulting in a long drying time and low drying efficiency. Summary of the invention

[0004] In view of this, the present invention provides a drying control method, electronic device and clothing processing device for a clothing processing device to solve the problem that the two clothing processing drums of an existing double-drum washing machine will result in a long drying time and low drying efficiency when the two clothing processing drums execute the drying program at the same time.

Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments.

[0056] Embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be construed as limiting the present invention.

[0057] like Figures 1 to 4 As shown, an exemplary embodiment of the present invention provides a clothes processing device 100. The clothes processing device 100 may include but is not limited to a washing machine, and the washing machine may include but is not limited to a washing and care machine, a washing and drying machine, etc. For example, the washing machine may be a drum washing machine or a pulsator washing machine with a drying or washing and care function, and of course, the washing machine may also be other types of fully automatic washing machines.

[0058] The clothing processing device 100 includes a plurality of clothing processing drums 110 and a drying duct 120. Among them, the number of the drying duct 120 is one. The plurality of clothing processing drums 110 are arranged in a first direction and share one drying duct 120. It should be noted that the first direction may be a vertical direction, that is, the plurality of clothing processing drums 110 are arranged vertically and spaced apart; or the first direction may also be a horizontal direction, that is, the plurality of clothing processing drums 110 are arranged horizontally and spaced apart.

[0059] In this example and the following examples, the laundry processing device 100 is described by taking a twin-drum washing machine as an example, wherein two laundry processing drums 110 are arranged vertically up and down. The drying air duct 120 has two or more outlets, and the two outlets are respectively connected to the two laundry processing drums 110, so that the two laundry processing drums 110 can be dried synchronously by using one drying air duct 120, thereby reducing the design size of the laundry processing device 100, and realizing the structural design of two laundry processing drums 110 sharing one drying air duct 120 in a smaller design space.

[0060] The upper laundry treatment drum 110 is defined as an upper laundry treatment drum 111, and the lower laundry treatment drum 112 is defined as a lower laundry treatment drum 112. It should be noted that both the upper laundry treatment drum 111 and the lower laundry treatment drum 112 can satisfy the needs of washing, rinsing and drying the laundry.

[0061] In one example, a branch pipe may be provided in the drying air duct 120, and a drying fan (not shown in the figure) and a drying module (not shown in the figure) are provided in the branch pipe, and the drying fan may be a variable frequency fan. The drying module is configured to dehumidify and heat the hot and humid gas drawn from the clothes processing drum, and form a drying airflow, which is re-delivered to the clothes processing drum 110 by the drying fan, thereby achieving drying treatment of the bound water in the clothes.

[0062] The drying module can be directly fixed in the drying air duct, or fixed in the drying air duct by other fasteners such as screws, etc. The drying module can be arranged at a position close to the air outlet end of the drying air duct.

[0063] It should be noted that the drying module may include but is not limited to an element capable of heating air, such as an electric heating wire or a PTC (Positive Temperature Coefficient) heater.

[0064] Along the moving direction of the drying airflow, the drying fan is located upstream of the drying module. Through the rotation of the drying fan, on the one hand, the hot and humid gas drawn out of the clothes processing drum 110 can be guided to the drying module, and the drying airflow can be formed by the dehumidification and heating of the drying module. On the other hand, the drying airflow can also be driven to any one or two clothes processing drums 110, and a suitable drying airflow flow rate can be provided for any one or two clothes processing drums 110 to meet the drying air volume requirements of the corresponding clothes processing drum 110. Alternatively, in the process of air-drying the clothes or cooling the clothes processing drum 110 in the later stage of the drying process, a suitable air volume is provided to meet the air-drying requirements of the clothes or the cooling requirements of the clothes processing drum 110.

[0065] Based on this structure, synchronous drying of two or more clothing processing drums 110 can be achieved by using one drying fan and one drying module.

[0066] like Figure 1 and Figure 2 As shown, in another example, two boxes 130 are provided at the connection position of the branch pipeline and the drying air duct 120, and the drying air duct 120 is divided into an upper drying air duct 121 and a lower drying air duct 122. The drying air duct 120 between the two boxes 130 and the upper laundry treatment drum 111 is the upper drying air duct 121, and the drying air duct 120 between the two boxes 130 and the lower laundry treatment drum 112 is the lower drying air duct 122.

[0067] It should be noted that an upper air outlet rubber ring 141 is provided at the connection position between the two device boxes 130 and the upper drying air duct 121, and a lower air outlet rubber ring 142 is provided at the connection position between the two device boxes 130 and the lower drying air duct 122 to ensure the sealing of the air duct connection.

[0068] An upper air distribution structure 131 and a lower air distribution structure 132 are also provided in the two device boxes 130. The upper air distribution structure 131 includes an upper air distribution piece 131a, and the lower air distribution structure 132 includes a lower air distribution piece 132a. When the upper air distribution piece 131a or the lower air distribution piece 132a is at different gears, the flow rate of the drying air flow introduced by the drying fan into the corresponding clothes processing drum 110 is different.

[0069] Reference Figure 3 As shown, the upper air-dividing blade 131a has five gears, and is divided into four areas within the 180° interval of the upper air-dividing structure 131, that is, each 45° is a gear area, that is, -90° to -45°, -45° to 0°, 0° to 45°, and 45° to 90°. When the upper air-dividing blade 131a is at the -90° position, the upper air-dividing structure 131 is in a fully closed state, and when the upper air-dividing blade 131a is at the 90° position, the upper air-dividing structure 131 is in a fully open state, and when the upper air-dividing blade 131a is at the middle 0° position, the upper air-dividing structure 131 is in a semi-open state.

[0070] Similarly, refer to Figure 4 As shown, the lower air dividing piece 132a has five gears, and the 180° interval of the lower air dividing structure 132 is divided into four areas, that is, every 45° is a gear area, that is, -90° to -45°, -45° to 0°, 0° to 45°, and 45° to 90°. Among them, when the lower air dividing piece 132a is at the -90° position, the lower air dividing structure 132 is in a fully closed state, and when the lower air dividing piece 132a is at the 90° position, the lower air dividing structure 132 is in a fully open state, and when the lower air dividing piece 132a is at the middle 0° position, the lower air dividing structure 132 is in a semi-open state.

[0071] That is to say, by using the upper air dividing blades 131a and the lower air dividing blades 132a in different gears, it is possible to achieve separate drying of the upper clothing processing drum 111, separate drying of the lower clothing processing drum 112, or simultaneous drying of the upper clothing processing drum 111 and the lower clothing processing drum 112, or simultaneous drying of the upper clothing processing drum 111 and the lower clothing processing drum 112 with different drying air flow rates.

[0072] like Figure 5As shown, an exemplary embodiment of the present invention provides a drying control method for a clothes processing device, and the drying control method is applied to the clothes processing device of any of the above embodiments. The drying control method for the clothes processing device includes the following steps:

[0073] Step S100: before any of the laundry processing drums is ready to execute a drying process, determining whether one of the remaining laundry processing drums is executing a drying process.

[0074] Step S200: If one of the remaining laundry processing drums is executing a drying program, the laundry processing drum executing the drying program and / or the laundry processing drum preparing to execute the drying program is selectively controlled based on a temperature strategy, and the temperature strategy is related to the drying stage and time of the laundry processing drum executing the drying program.

[0075] In step S100, before one of the laundry processing drums 110 is ready to execute the drying program, it is first determined whether any of the remaining multiple laundry processing drums 110 is executing the drying program. Taking a twin-drum washing machine as an example, when the laundry in the upper laundry processing drum 111 is washed or rinsed, it needs to be dried. At this time, the control system will first obtain whether the lower laundry processing drum 112 is executing the drying program.

[0076] When the lower laundry processing drum 112 is not performing a drying program, the upper air dividing plate 131a in the upper air dividing structure 131 can be adjusted from a -90° position to a 90° position to dry the clothes in the upper laundry processing drum 111 using the drying fan and drying module in the drying air duct 120.

[0077] In step S200, when the lower laundry treatment drum 112 is performing a drying process, the drying conditions of the upper laundry treatment drum 111 and the lower laundry treatment drum 112 are controlled based on a temperature strategy. The temperature strategy is related to the drying stage and time of the lower laundry treatment drum 112.

[0078] For example, when the lower clothes processing drum 112 is in the early or middle stage of the drying stage, that is, the clothes in the lower clothes processing drum 112 are in the early or middle stage of the drying stage, reducing the drying air flow rate input into the lower clothes processing drum 112 at this time will not affect the drying situation in the lower clothes processing drum 112, that is, it will not have a significant impact on the drying temperature of the lower clothes processing drum 112. At this time, the gear positions of the upper dividing air plate 131a and the lower dividing air plate 132a can be adjusted so that drying air flows into both the upper clothes processing drum 111 and the lower clothes processing drum 112 to achieve synchronous drying of the upper clothes processing drum 111 and the lower clothes processing drum 112, thereby effectively ensuring the drying efficiency of the clothes processing equipment.

[0079] For another example, when the lower clothes processing drum 112 is in the late stage of the drying judgment stage, that is, when the clothes in the lower clothes processing drum 112 are in the late stage of the drying stage, reducing the drying airflow rate input into the lower clothes processing drum 112 at this time may have a significant impact on the drying conditions in the lower clothes processing drum 112, causing the drying temperature of the lower clothes processing drum 112 to fluctuate greatly, which may cause the lower clothes processing drum 112 to be re-judged dry due to temperature changes, thereby affecting the drying stability and drying effect of the lower clothes processing drum 112.

[0080] Therefore, when the lower laundry treatment drum 112 is in the late stage of the drying judgment stage, the control system based on the twin-drum washing machine controls the upper air dividing blade 131a to continue to be at the -90° position, and the upper laundry treatment drum 111 does not perform the drying process temporarily. After the lower laundry treatment drum 112 completes the drying process, the upper laundry treatment drum 111 is controlled to start the drying process.

[0081] It should be noted that the control system of the twin-drum washing machine can adopt the control device in the prior art, as long as the control device can control various start-up functions of the twin-drum washing machine, and the specific structure type and specific control logic of the control device will not be repeated here.

[0082] In this example, the opening or closing of the clothes processing drum 110 (i.e., the upper clothes processing drum 111) that is preparing to execute the drying program is adjusted according to the drying period of the clothes processing drum 110 (i.e., the lower clothes processing drum 112) that is executing the drying program, wherein, when the upper clothes processing drum 111 meets the opening conditions, synchronous drying of two or more clothes processing drums 110 is achieved, saving the time for drying clothes, and when the upper clothes processing drum 111 does not meet the opening conditions, the drying effect of the lower clothes processing drum 112 and the stability of the drying process are guaranteed first, thereby ensuring the overall drying efficiency and drying effect of the clothes processing equipment, thereby improving the user experience.

[0083] like Figure 6 As shown, in some embodiments, the drying stage includes a drying temperature difference stage, that is, during the drying process, as the bound water in the clothes is continuously dried, when the control system determines that the bound water content in the clothes is reduced to a certain level, such as 3% or less, or when the drying temperature in the clothes treatment drum 110 is always within a certain range within a set time, it is determined that the clothes have been dried. When the clothes treatment drum 110 is in the drying temperature difference stage, it indicates that the drying process of the clothes treatment drum 110 is about to end.

[0084] The process of selectively controlling the laundry processing drum that is performing a drying process and / or the laundry processing drum that is ready to perform a drying process based on a temperature strategy comprises the following steps:

[0085] The control system determines whether the clothes processing drum 110 that is executing the drying process, that is, the lower clothes processing drum 112, has reached the drying temperature difference stage.

[0086] When the lower laundry processing drum 112 reaches the temperature difference stage for judging dryness, the operation time Tn of the lower laundry processing drum 112 reaching the temperature difference stage for judging dryness is collected through the control system.

[0087] The relationship between the running time Tn and the first time T1 is determined, wherein the value range of the first time T1 is 30 minutes to 60 minutes.

[0088] According to the size relationship, the lower laundry processing tub 112 or the upper laundry processing tub 111 is selectively controlled.

[0089] like Figure 6 As shown, in some embodiments, when the running time Tn is less than the first time T1, it indicates that the time for the lower clothing processing drum 112 to enter the drying temperature difference stage is still relatively short, and when the drying air flow rate input into the lower clothing processing drum 112 is reduced, it will not affect the drying condition in the lower clothing processing drum 112, that is, it will not have a significant impact on the drying temperature of the lower clothing processing drum 112. At this time, by adjusting the gear positions of the upper air dividing plate 131a and the lower air dividing plate 132a, drying air flows into both the upper clothing processing drum 111 and the lower clothing processing drum 112, so as to realize synchronous drying of the upper clothing processing drum 111 and the lower clothing processing drum 112, thereby effectively ensuring the drying efficiency of the clothing processing equipment.

[0090] In a specific example, when the operation time Tn is less than the first time T1, the drying air flow rate entering the upper laundry treatment drum 111 and the lower laundry treatment drum 112 can also be controlled based on the moisture content of the laundry in the lower laundry treatment drum 112.

[0091] When Tn<T1, the moisture content of the clothes in the lower clothes processing drum 112 is obtained based on the humidity sensor or the temperature and humidity sensor in the clothes processing apparatus 100.

[0092] When the moisture content is less than or equal to the set humidity threshold, it indicates that the moisture content of the clothes in the lower laundry treatment drum 112 is small, that is, the remaining time for drying the clothes in the lower laundry treatment drum 112 is small, and at this time, the clothes in the lower laundry treatment drum 112 can be dried quickly. The control system controls the gear position of the air dividing plate so that the drying air flow entering the lower laundry treatment drum 112 is greater than the drying air flow entering the upper laundry treatment drum 111. For example, the upper air dividing plate 131a in the upper air dividing structure 131 is set at a -45° position, and the lower air dividing plate 132a in the lower air dividing structure 132 is set at a 45° position.

[0093] Among them, after the lower clothing processing drum 112 finishes the drying process, the upper air dividing plate 131a in the upper air dividing structure 131 is adjusted from the -45° position to the 90° position, and the lower air dividing plate 132a in the lower air dividing structure 132 is adjusted from the 45° position to the -90° position, thereby controlling the entire drying air flow to enter the upper clothing processing drum 111 to speed up the drying efficiency of the clothes in the upper clothing processing drum 111.

[0094] When the moisture content is greater than the set humidity threshold, it indicates that the moisture content of the clothes in the lower clothing processing drum 112 is relatively large. At this time, based on the control system, the upper air dividing plate 131a in the upper air dividing structure 131 can be adjusted from the -90° position to the 0° position, and the lower air dividing plate 132a in the lower air dividing structure 132 can be adjusted from the 90° position to the 0° position, so that the upper clothing processing drum 111 and the lower clothing processing drum 112 can be dried synchronously with the same drying air flow rate.

[0095] It should be noted that the humidity threshold value range may be the value set when the device leaves the factory, or may be a value flexibly set by the user according to the actual drying requirements of the clothes. In a specific example, the humidity threshold value range is 30% to 50%.

[0096] When the running time Tn is greater than or equal to the first time T1, it indicates that the lower clothes processing drum 112 takes a long time to enter the drying temperature difference stage. At this time, the lower clothes processing drum 112 may be in the late stage of the drying stage. Reducing the drying airflow flow input into the lower clothes processing drum 112 will have a greater impact on the drying conditions in the lower clothes processing drum 112, causing the drying temperature of the lower clothes processing drum 112 to fluctuate greatly. This may cause the lower clothes processing drum 112 to be re-judged dry due to temperature changes, which will affect the drying stability and drying effect of the lower clothes processing drum 112.

[0097] At this time, the control system obtains the remaining drying time Tm of the lower laundry processing drum 112, and then controls the lower laundry processing drum 112 and the upper laundry processing drum 111 according to the relationship between the remaining drying time Tm and the second time T2. The value range of the second time T2 is 10 minutes to 35 minutes.

[0098] When the remaining drying time Tm is less than the second time T2, it indicates that the lower laundry processing drum 112 may be in the late stage of the drying stage. At this time, the control system based on the twin-drum washing machine controls the upper air blade 131a to continue to be at the -90° position, that is, the upper laundry processing drum 111 does not perform drying processing temporarily.

[0099] In the process that the lower laundry processing drum 112 continues to run the drying program, it is determined in real time based on the control system whether the drying temperature difference determination stage of the lower laundry processing drum 112 has ended.

[0100] When it is judged that the drying temperature difference stage has ended, it indicates that the lower clothing processing drum 112 has completed the drying program. At this time, based on the control system, the upper air dividing blade 131a is controlled to be adjusted from the -90° position to the 90° position, and the lower air dividing blade 132a is adjusted from the 90° position to the -90° position, so that all the drying air flow flows into the upper clothing processing drum 111 to dry the clothes in the upper clothing processing drum 111.

[0101] When it is determined that the drying temperature difference stage is not over, the upper laundry processing drum 111 is controlled to continue waiting.

[0102] When the remaining drying time Tm is greater than or equal to the second time T2, based on the control system, the upper air dividing plate 131a in the upper air dividing structure 131 is adjusted from the -90° position to the 0° position, and the lower air dividing plate 132a in the lower air dividing structure 132 is adjusted from the 90° position to the 0° position, so that the upper clothing processing drum 111 and the lower clothing processing drum 112 are synchronously dried with the same drying air flow rate.

[0103] In one example, when Tm≥T2, the step of controlling the lower laundry treatment tub 112 and the upper laundry treatment tub 111 to dry synchronously may include the following process:

[0104] A plurality of weight change values ​​of the clothes in the lower clothes treatment drum 112 in N unit time are obtained based on the weight sensor in the clothes treatment device 100 or by using the rotation frequency or rotation current of the driving motor driving the clothes treatment drum 110 to rotate, wherein N is an integer value greater than or equal to 2. The unit time can be any value between 0.1 min and 0.5 min.

[0105] When the amplitude of the continuous weight change values ​​is small within N unit time, it indicates that the weight of the clothes in the lower laundry treatment drum 112 is close to being stable, that is, the moisture content of the bound water of the clothes is small, that is, the lower laundry treatment drum 112 is in the late stage of the drying stage. The control system controls the gear position of the air divider so that the drying air flow entering the lower laundry treatment drum 112 is greater than the drying air flow entering the upper laundry treatment drum 111. For example, the upper air divider 131a in the upper air divider structure 131 is set at a -45° position, and the lower air divider 132a in the lower air divider structure 132 is set at a 45° position. After the lower clothing processing drum 112 finishes the drying process, the upper air dividing plate 131a in the upper air dividing structure 131 is adjusted from the -45° position to the 90° position, and the lower air dividing plate 132a in the lower air dividing structure 132 is adjusted from the 45° position to the -90° position. In this way, all the drying air flow is controlled to enter the upper clothing processing drum 111, so as to speed up the drying efficiency of the clothes in the upper clothing processing drum 111, which is beneficial to improving the user experience.

[0106] When the amplitude of the continuous weight change rate is large within N unit time, it indicates that the moisture content of the bound water in the clothes is relatively high during the clothes drying process. At this time, the gear position of the air dividing plate can be controlled by the control system so that the upper clothes processing drum 111 and the lower clothes processing drum 112 are synchronously dried with the same drying air flow rate. That is, based on the control system, the upper air dividing plate 131a in the upper air dividing structure 131 is adjusted from the -90° position to the 0° position, and the lower air dividing plate 132a in the lower air dividing structure 132 is adjusted from the 90° position to the 0° position, so that the upper clothes processing drum 111 and the lower clothes processing drum 112 are synchronously dried with the same drying air flow rate.
