Description

Technical Field

[0001] This application relates to the field of household appliance technology, and in particular to a clothing processing device and its control method. Background Technology

[0002] Some garment processing equipment can not only wash and dehydrate clothes, but also dry them. In particular, the garment processing equipment dries clothes through a drying system. When the drying process begins, a fan supplies air into the inner drum that holds the clothes. A heating device generates heat to heat the supplied air, so that the hot air carries the moisture from the clothes as it flows through the inner drum, forming humid hot air. This humid hot air then enters the circulating air duct through the air outlet of the inner drum. A condenser uses cooling water to reduce the temperature and humidity of the humid hot air, and finally, the condenser also discharges the cooling water.

[0003] However, existing garment processing equipment requires a large amount of condensate water when drying clothes, resulting in high energy consumption and high costs when performing the drying process. Summary of the Invention

[0004] This application provides a garment processing device and its control method to overcome the technical problem that the garment processing device in the prior art has a large demand for condensate water when drying clothes, thereby reducing the energy consumption and cost of the garment processing device when performing the drying process.

[0005] This application provides a garment processing device, comprising: a housing; an outer cylinder disposed within the housing; an inner cylinder rotatably fitted inside the outer cylinder, the interior of the inner cylinder being used to load garments, and the inner cylinder having an inlet for loading garments; and a drying system disposed within the housing, the drying system comprising: a fan for supplying air to the air inlet of the inner cylinder; a heating device disposed in the air outlet direction of the fan for heating the air supplied by the fan to the interior of the inner cylinder; a circulating air duct disposed between the air outlet of the inner cylinder and the air inlet of the fan; and a first condensation device disposed in the circulating air duct. A side wall is provided for reducing the temperature of the air discharged from the air outlet of the inner cylinder by means of cooling water and for discharging the cooling water; a second condensing device is provided next to the water inlet of the first condensing device for reducing the temperature of the air discharged from the air outlet of the inner cylinder by means of heat exchange; and a controller is configured to, when executing a drying program, control the fan to operate to provide air to the air inlet of the inner cylinder, control the heating device to operate to heat the air provided by the fan to the air inlet of the inner cylinder, and control the second condensing device to operate to reduce the temperature of the air discharged from the air outlet of the inner cylinder, and control the first condensing device to not operate.

[0006] The clothing processing equipment provided in this embodiment can use a second condensing device to reduce the temperature of the air through heat exchange when drying clothes. Compared to the first condensing device, which consumes condensate water, the second condensing device in this embodiment does not consume condensate water while working to reduce the temperature of the air discharged from the inner drum's outlet. Therefore, when the clothing processing equipment is drying clothes, the use of the second condensing device can reduce the consumption of condensate water, thereby reducing the energy consumption and cost of the clothing processing equipment during the drying process. Furthermore, since the clothing processing equipment provided in this embodiment is equipped with two condensing devices, it can specifically control one of the first and second condensing devices to operate while the other remains inactive during the drying process, meeting the drying needs of different scenarios and enriching the application scenarios of the clothing processing equipment.

[0007] In one embodiment of this application, the controller is specifically configured to: control the second condenser to operate and control the first condenser to not operate when at least one of the following conditions is met: the weight of the clothes in the inner drum is less than or equal to the first preset value, the humidity of the clothes in the inner drum is less than or equal to the second preset value, or the ratio of the dried time of the clothes in the inner drum to the total drying time is greater than a third preset value.

[0008] The clothing processing equipment provided in this embodiment can control the second condenser to work and the first condenser to not work when there are few clothes, the clothes are relatively dry, or the drying process is nearing its end. This is to reduce the temperature and humidity of the air through heat exchange. Since the second condenser can reduce the temperature of the air to achieve the drying process, and since the second condenser does not need to consume condensate, it can reduce the ineffective consumption of cooling water in some scenarios.

[0009] A second aspect of this application provides a clothing handling device, comprising: a housing; an outer cylinder disposed within the housing; an inner cylinder rotatably fitted inside the outer cylinder, the interior of the inner cylinder being used to load clothing, and the inner cylinder having an inlet for loading clothing; and a drying system disposed within the housing, the drying system comprising: a fan for supplying air to the air inlet of the inner cylinder; a heating device disposed in the air outlet direction of the fan for heating the air supplied by the fan to the interior of the inner cylinder; a circulating air duct disposed between the air outlet of the inner cylinder and the air inlet of the fan; and a first condensing device disposed on the side wall of the circulating air duct for reducing the temperature of the air discharged from the air outlet of the inner cylinder by means of cooling water. The system includes a first condenser, which is located next to the inlet of the first condenser and is used to reduce the temperature of the air discharged from the outlet of the inner cylinder by heat exchange; and a controller configured to, when executing the drying program, control the fan to operate to provide air to the air inlet of the inner cylinder, control the heating device to operate to heat the air provided by the fan to the air inlet of the inner cylinder, control the first condenser to operate to reduce the temperature of the air discharged from the outlet of the inner cylinder, and control the second condenser to not operate; and control the first condenser to operate to reduce the temperature of the air discharged from the outlet of the inner cylinder, and control the second condenser to not operate.

[0010] The clothing processing equipment provided in this embodiment can use a first condensing device to reduce the temperature of the air during drying, achieving more efficient drying. The condensate further reduces the air temperature, shortening the drying time to some extent. Simultaneously, since the clothing processing equipment also includes a second condensing device, which does not consume condensate while working to reduce the temperature of the air discharged from the inner drum's outlet, condensate consumption can be reduced during drying. Specifically, the clothing processing equipment can control one of the first and second condensing devices to operate while the other remains inactive, meeting different drying needs and energy consumption requirements in various scenarios. This enriches the application scenarios of the clothing processing equipment, provides users with more choices, and improves the user experience.

[0011] In one embodiment of this application, the controller is specifically configured to: when the weight of the clothes in the inner drum is greater than a first preset value, the humidity of the clothes in the inner drum is greater than a second preset value, or the ratio of the dried time of the clothes in the inner drum to the total drying time is less than or equal to a third preset value, control the first condensing device to work and control the second condensing device to not work.

[0012] The clothing processing equipment provided in this embodiment can control the first condenser to work and the second condenser to not work when there are many clothes to be dried, the clothes are relatively damp, or the drying process is close to the start time. This allows the condensed water to more effectively reduce the temperature and humidity of the hot and humid air, thereby shortening the drying time to a certain extent.

[0013] In one embodiment of this application, the second condensation device includes: a cooling plate disposed inside the side wall of the circulating air duct for heat exchange with the hot and humid air in the circulating air duct; a heat sink connected to the cooling plate and disposed outside the side wall of the circulating air duct for heat exchange with the cooling plate; and a cooling fan connected to the heat sink for reducing the temperature of the heat sink.

[0014] The clothing processing equipment provided in this embodiment has a relatively simple structure and is stable and reliable, which is more conducive to the application and promotion of this embodiment.

[0015] In one embodiment of this application, the controller is further configured to: when controlling the second condenser to work, control the speed of the cooling fan to a first speed or a second speed according to the weight, humidity or drying progress of the clothes in the inner drum, wherein the first speed is greater than the second speed.

[0016] The clothing processing device provided in this embodiment can, when there is a large amount of heat that needs to be dissipated, control the cooling fan to achieve heat dissipation by increasing its speed and reducing the time required for heat dissipation. When there is a small amount of heat that needs to be dissipated, the controller controls the cooling fan to reduce its speed and reduce its energy consumption to save costs.

[0017] In one embodiment of this application, the controller is specifically configured to: control the speed of the cooling fan of the second condenser to a first speed when at least one of the following conditions is met: the weight of the clothes in the inner drum is greater than a fourth preset value, the humidity of the clothes in the inner drum is greater than a fifth preset value, or the ratio of the dried time of the clothes in the inner drum to the total drying time is greater than a sixth preset value; and control the speed of the cooling fan of the second condenser to a first speed when at least one of the following conditions is met: the weight of the clothes in the inner drum is less than or equal to the fourth preset value, the humidity of the clothes in the inner drum is less than or equal to the fifth preset value, or the ratio of the dried time of the clothes in the inner drum to the total drying time is less than or equal to the sixth preset value.

[0018] The garment processing equipment provided in this embodiment can meet the drying needs in different scenarios, and further refines the adjustment of the cooling fan speed in different scenarios, thereby enriching the application scenarios of the garment processing equipment and further improving the user experience of the garment processing equipment.

[0019] In one embodiment of this application, when the first condensing device is controlled to operate, if at least one of the following conditions is met: the weight of the clothes in the inner drum is less than or equal to the first preset value, the humidity of the clothes in the inner drum is less than or equal to the second preset value, or the ratio of the dried time of the clothes in the inner drum to the total drying time is greater than a third preset value, the second condensing device is controlled to operate, and the first condensing device is controlled to not operate; when the second condensing device is controlled to operate, if at least one of the following conditions is met: the weight of the clothes in the inner drum is greater than the first preset value, the humidity of the clothes in the inner drum is greater than the second preset value, or the ratio of the dried time of the clothes in the inner drum to the total drying time is less than or equal to the third preset value, the first condensing device is controlled to operate, and the second condensing device is controlled to not operate.

[0020] The controller of the clothing processing equipment provided in this embodiment can still switch between different condensing devices in real time according to the changes in weight, humidity and other factors of the clothes in the inner drum when executing the drying program. It can use a more suitable condensing device more flexibly according to the real-time state of the clothes, further ensuring the effectiveness and real-time operation of the condensing device. Different condensing devices can be automatically switched throughout the drying process, which also improves the intelligence and automation of the clothing processing equipment.

[0021] The third aspect of this application provides a control method for a garment processing device, which can be applied to the garment processing device provided in the first aspect of this application. The control method includes: when executing a drying program, controlling the fan to operate to provide air to the air inlet of the inner drum; controlling the heating device to operate to heat the air provided by the fan to the air inlet of the inner drum; controlling the second condensing device to operate to reduce the temperature of the air discharged from the air outlet of the inner drum; and controlling the first condensing device to not operate.

[0022] The fourth aspect of this application provides a control method for a garment processing device, which can be applied to the garment processing device provided in the second aspect of this application. The control method includes: when executing a drying program, controlling the fan to operate to provide air to the air inlet of the inner drum; controlling the heating device to operate to heat the air provided by the fan to the air inlet of the inner drum; controlling the first condensing device to operate to reduce the temperature of the air discharged from the air outlet of the inner drum; and controlling the second condensing device to not operate.

[0023] The fifth aspect of this application provides a computer-readable storage medium storing computer-executable instructions, which, when executed, implement the control method of the clothing processing device as described in the third or fourth aspect of this application.

[0024] The sixth aspect of this application provides a computer program product, including a computer program that, when executed, implements the control method for the clothing processing equipment as described in the third or fourth aspect of this application. Attached Figure Description

[0039] Figure 1 A schematic diagram of a garment processing device provided in this application, such as... Figure 1 The garment processing equipment 1 shown can specifically be a washer-dryer combo.

[0040] like Figure 1 As shown, the garment processing device 1 provided in this application embodiment includes: a housing 13, an outer drum 11, an inner drum 12, a drying system, and a controller 20.

[0041] The housing 13 is the outer shell of the entire garment processing equipment 1, used to house and support the overall structure of the garment processing equipment 1.

[0042] The outer cylinder 11 is located inside the box body 13 to accommodate the inner cylinder 12. The outer cylinder 11 is also provided with an opening corresponding to the loading port of the inner cylinder 12.

[0043] The inner tube 12 is disposed inside the outer tube 11, and the inner tube 12 has an inlet for inserting clothes, which matches the opening of the outer tube 11. At the same time, the outer surface of the inner tube 12 is fitted inside the inner surface of the outer tube 11, so that the inner tube 12 can rotate inside the outer tube 11.

[0044] In one embodiment, the garment processing device 1 further includes a motor, which can be used to drive the inner drum 12 to rotate, and the controller 20 can be used to control the rotation speed of the inner drum 12 through the motor.

[0045] Figure 2 This application provides a schematic diagram of the structure of a garment processing device, such as...Figure 2 The garment processing device 1 shown is in Figure 1 Based on the clothing processing equipment 1 shown, it also includes a drying system, which is installed inside the housing 13, specifically in the space between the housing 13 and the outer cylinder 11.

[0046] In one embodiment, such as Figure 2 The drying system of the garment processing equipment 1 shown includes: a fan 21, a heating device 22, a circulating air duct 24, and a first condenser 25.

[0047] The fan 21 is used to supply air to the air inlet of the inner cylinder 12.

[0048] The heating device 22 is set in the air outlet direction of the fan. When the fan 21 supplies air to the air inlet of the inner cylinder 12, the heating device 22 can heat the air supplied by the fan 21 to the inner cylinder 12, so that the air entering the inner cylinder 12 through the air inlet of the inner cylinder 12 is dry and hot air.

[0049] The circulating air duct 21 is set between the air outlet of the inner cylinder 12 and the air inlet of the fan 21, so that the air outlet a of the fan 21, the air inlet b of the inner cylinder 12, the air outlet c of the inner cylinder 12, the air inlet d of the circulating air duct 24, the air outlet e of the circulating air duct 24 and the air inlet f of the fan 21 are located between them.

[0050] Specifically, the controller 20 can control the fan 21 to operate and supply air to the air inlet of the inner cylinder 12, and control the heating device 22 to operate and heat the air supplied by the fan 21 to the air inlet of the inner cylinder 12, forming according to... Figure 2 The sequence of abcdef forms a cyclical wind.

[0051] The first condensing device 25 is installed on the side wall of the circulating air duct 24. When the dry and hot air entering the inner cylinder 12 through the air inlet passes through the clothes in the inner cylinder 12, the air discharged from the air outlet of the inner cylinder 12 is humid and hot air carrying the moisture of the clothes. Then the controller 20 can also control the first condensing device 25 to work, so that the first condensing device 25 reduces the temperature of the air discharged from the air outlet of the inner cylinder 12 by cooling water entering from the water inlet g. When the water in the humid and hot air in the air is separated, the cooling water is discharged from the water outlet h.

[0052] like Figure 2 Although the clothing processing device 1 shown can dry clothes, the drying system requires a large amount of condensate to cool the air discharged from the air outlet of the inner drum 12. This results in a large demand for condensate in the clothing processing device 1, leading to high energy consumption and high cost when drying clothes.

[0053] Based on this, this application also provides a garment processing device to reduce energy consumption and cost when drying garments. The technical solution of this application will be described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0054] Figure 3 A schematic diagram of another garment processing device provided in this application is shown below. Figure 3 The garment processing device 1 shown is in Figure 2 Based on the clothing processing equipment 1 shown, a second condensation device 23 is also included.

[0055] Specifically, the second condensing device 23 is located next to the water inlet of the first condensing device 25, and can reduce the temperature of the air discharged from the air outlet of the inner cylinder 12 through heat exchange.

[0056] In one embodiment, the controller 20 can control the second condensing device 23 to operate, causing the second condensing device 25 to reduce the temperature of the air discharged from the air outlet of the inner drum 12 through heat exchange. It can be seen that during the process of the second condensing device 25 operating to reduce the temperature of the air discharged from the air outlet of the inner drum 12, the second condensing device 25 does not consume condensate. Therefore, the use of the second condensing device 25 when drying clothes can reduce the consumption of condensate, thereby reducing the energy consumption and cost of the clothes drying equipment 1.

[0057] In one embodiment, due to, as Figure 3 The drying system of the clothing processing device 1 shown has two condensing devices. Therefore, when the clothing processing device 1 is drying clothes, the controller 20 can control one of the first condensing device 25 and the second condensing device 23 to work and the other to not work, so as to meet the drying needs in different scenarios and enrich the application scenarios of the clothing processing device 1.

[0058] For example, the controller 20 controls the first condensing device 25 to operate, so as to reduce the temperature of the air discharged from the air outlet of the inner cylinder 12 by cooling water and discharge the cooling water. While controlling the first condensing device 25 to operate, the controller 20 controls the second condensing device 23 to not operate.

[0059] In one specific implementation, the controller 20 can make the first condensing device 25 work by controlling the power supply circuit to power on the first condensing device 25, and can make the second condensing device 23 not work by controlling the power supply circuit to not power on the second condensing device 23.

[0060] For example, controller 20 controls the second condensing device 23 to work, so as to reduce the temperature of the air discharged from the air outlet of the inner cylinder 12 through heat exchange. While controlling the second condensing device 25 to work, controller 20 controls the first condensing device 25 to not work.

[0061] In one specific implementation, the controller 20 can enable the second condensing device 23 to operate by controlling the power supply circuit to power it, and disable the first condensing device 25 by controlling the power supply circuit to de-power it.

[0062] In one embodiment, the controller 20 may specifically control one of the first condensing device 25 or the second condensing device 23 to operate based on at least one of the weight, humidity or drying progress of the clothes in the inner drum 12, so as to reduce the temperature of the air discharged from the air outlet of the air duct 12.

[0063] Specifically, when at least one of the weight, humidity, or drying progress of the clothes in the inner drum 12 meets the working conditions of the first condensing device 25, the controller 20 controls the first condensing device 25 to work and controls the second condensing device 23 to not work.

[0064] When at least one of the following conditions—the weight, humidity, or drying progress of the clothes in the inner drum 12—meets the operating conditions of the second condenser 23, the controller 20 controls the second condenser 23 to operate and controls the first condenser 25 to not operate.

[0065] Figure 4 A schematic diagram of the first type of working condition provided for this application, such as Figure 4 In the illustrated embodiment, the first condenser 25 operates when the weight of the clothes is greater than a first preset value, and the second condenser 23 operates when the weight of the clothes is less than or equal to the first preset value, which can be, for example, 4 kg. When the controller 20 determines that the weight of the clothes to be dried in the inner drum 12 is greater than the first preset value, indicating a large amount of clothes to be dried, the controller 20 controls the first condenser 25 to operate and the second condenser 23 to not operate, so as to more effectively reduce the air temperature through condensation and shorten the drying time to a certain extent. When the controller 20 determines that the weight of the clothes to be dried in the inner drum 12 is less than or equal to the first preset value, indicating a small amount of clothes to be dried, the controller 20 controls the second condenser 23 to operate and the first condenser 25 to not operate, so as to reduce the air temperature through heat exchange. The second condenser 23 can also reduce the air temperature, thereby achieving the drying process of the clothes. Since the second condenser 23 does not consume condensation water, it can reduce the ineffective consumption of cooling water when there are few clothes.

[0066] Figure 5A schematic diagram of the second type of working condition provided in this application, as shown below. Figure 5 In the illustrated embodiment, the first condenser 25 operates when the humidity of the clothes is greater than a second preset value, and the second condenser 23 operates when the weight of the clothes is less than or equal to the second preset value. When the controller 20 determines that the humidity of the clothes to be dried in the inner drum 12 is greater than the second preset value, indicating that the clothes to be dried are relatively damp, the controller 20 controls the first condenser 25 to operate and controls the second condenser 23 to not operate, so as to more effectively reduce the temperature of the air through condensation and shorten the drying time to a certain extent. When the controller 20 determines that the humidity of the clothes to be dried in the inner drum 12 is less than or equal to the second preset value, indicating that the clothes to be dried are relatively dry, the controller 20 controls the second condenser 23 to operate and controls the first condenser 25 to not operate, so as to reduce the temperature of the air through heat exchange. The second condenser 23 can also reduce the temperature of the air to achieve the drying process of the clothes. Since the second condenser 23 does not consume condensation water, it can reduce the ineffective consumption of cooling water when the clothes are relatively dry.

[0067] Figure 6 A schematic diagram of the third type of working condition provided for this application, as shown below. Figure 6 In the illustrated embodiment, the first condenser 25 operates when the ratio of the drying time of the clothes in the inner drum 12 to the total drying time is less than or equal to a third preset value, and the second condenser 23 operates when the ratio of the drying time of the clothes in the inner drum 12 to the total drying time is greater than the third preset value. Specifically, if the controller 20 starts executing the clothes drying program at time t1, and the total drying time required for the program is T, then the controller 20 determines the drying progress by comparing the ratio of t-t1 to T with the third preset value at the current time t. When the controller 20 determines that the ratio of the drying time of the clothes to be dried in the inner drum 12 to the total drying time is less than or equal to the third preset value, indicating that the drying program is closer to its start time, the controller 20 controls the first condenser 25 to operate and the second condenser 23 to not operate, so as to more effectively reduce the air temperature through condensation. When the controller 20 determines that the ratio of the drying time of the clothes to be dried in the inner drum 12 to the total drying time is greater than the third preset value, it means that the drying program is closer to the end. Then the controller 20 controls the second condenser 23 to work and controls the first condenser 25 to not work, so as to reduce the temperature of the air through heat exchange, thereby achieving the drying process of the clothes. Since the second condenser 23 does not need to consume condensate water, it does not need to continuously consume condensate water during the total drying time of the entire drying program, which can also reduce the ineffective consumption of cooling water.

[0068] In one embodiment, the controller 20 can obtain information such as the weight and humidity of the clothing through sensors installed in the clothing processing device 1, or the controller 20 can also receive information such as the weight and humidity of the clothing sent by other devices.

[0069] In one embodiment, the first preset value, the second preset value, and the third preset value may be specified, may be pre-configured, or may be user-set by the clothing processing device 1.

[0070] In one embodiment, the operating conditions of the first condensing device 25 can be combined. For example, if the operating conditions of the first condensing device are that the weight of the clothes in the inner drum 12 is greater than a first preset value and the humidity is greater than a second preset value, then the controller 20 will only control the first condensing device 25 to operate and the second condensing device 23 to not operate if both conditions are met simultaneously. Furthermore, if the operating conditions of the first condensing device 25 and the second condensing device 23 contradict each other, a certain priority can be set to achieve a more complete control logic. For example, if the priority is weight greater than humidity greater than drying progress, then if the weight of the clothes is greater than the first preset value and the humidity is less than the second preset value, the controller 20 will prioritize the first preset value (weight of the clothes being greater than the first preset value) to control the first condensing device 25 to operate, and the lower priority humidity condition will not be considered.

[0071] In one embodiment, the garment handling device 1 is a washer-dryer combo. The controller 20 can begin the drying program after the washing cycle ends, and the controller 20 first determines the drying process based on... Figures 4-6 The method shown determines that the first condenser 25 or the second condenser 23 is controlled to operate during the drying process.

[0072] In another embodiment, while executing the drying program, the controller 20 can still switch between different condensing devices in real time according to changes in the weight and humidity of the clothes in the inner drum 12. This allows for more flexible use of a more suitable condensing device based on the real-time condition of the clothes, further ensuring the effectiveness of the condensing device operation.

[0073] For example, when the controller 20 controls the first condenser 25 to operate, at a first moment, if the weight, humidity, or drying progress of the clothes in the inner drum 12 meets the operating conditions of the second condenser 23, the controller controls the second condenser 23 to operate after the first moment and controls the first condenser 25 to stop operating, thus achieving the switching from the first condenser 25 to the second condenser 23. As another example, when the controller 20 controls the second condenser 23 to operate, if the weight, humidity, or drying progress of the clothes in the inner drum 12 meets the operating conditions of the first condenser 25, the controller controls the first condenser 25 to operate and controls the second condenser 23 to stop operating, thus achieving the switching from the second condenser 23 to the first condenser 25.

[0075] like Figure 7 and Figure 8 As shown, the air inlet of the fan 21 is connected to the air outlet of the inner cylinder 12 through the circulating air duct 24, and the air outlet of the fan 21 is connected to the air inlet of the inner cylinder 12. At the same time, the outer cylinder 11 is also provided with corresponding openings.

[0076] The first condensing device 25 is installed inside the side wall of the circulating air duct 24. The second condensing device 23 is installed on the side wall of the circulating air duct 24, specifically next to the water inlet 210 of the first condensing device 25, as shown in the image. Figure 8 In the example shown, the second condenser 23 is located opposite the water inlet 210 of the first condenser 25, which can have a stronger dehumidification and cooling effect compared to the position of the second condenser 23 located on the side of the motor at the rear of the outer cylinder 12.

[0077] Figure 9 A schematic diagram of a second condensation device provided in this application is shown below. Figure 9 The second condensation device 23 shown includes a cooling plate 231, a heat sink 232, and a cooling fan 233. Its structure is relatively simple, stable, and reliable, which is more conducive to the application and promotion of the embodiments of this application.

[0078] The cooling element 231 is disposed inside the side wall of the circulating air duct 24 and is used to directly contact the air inside the circulating air duct 24, thereby exchanging heat with the hot and humid air to reduce the temperature and humidity of the air.

[0079] The heat sink 232 is connected to the cooling chip 231 and is located on the outside of the side wall of the circulating air duct 24 for heat exchange with the cooling chip 232.

[0080] Cooling fan 233 is connected to heat sink 232 to reduce the temperature of heat sink 232.

[0081] More specifically, combined Figure 7 and Figure 9 The circulating air duct 24 has openings 241 and 242 on its side wall. The openings 241 and 242 match the first part 231a and the second part 231b of the cooling plate 231 of the second condensing device 23, so that the first part 231a and the second part 231b of the cooling plate 231 of the second condensing device 23 enter the interior of the circulating air duct 24 through the openings 241 and 242. At the same time, the heat sink 232 of the second condensing device 23 remains outside the circulating air duct 24.

[0082] In one embodiment, such as Figure 9 The second condensing device 23 shown can specifically be a semiconductor refrigeration device. Figure 10 This is a schematic diagram illustrating the working principle of the semiconductor cooling device provided in this application, such as... Figure 10 As shown, the principle of the semiconductor cooling device is based on a pair of thermocouples composed of two completely different semiconductor materials, P-type and N-type. The charge carriers (free electrons) in both P-type and N-type materials have the same number of charges but opposite signs. When an electric current is applied to the P-type and N-type semiconductors, heat is absorbed at the upper cold end (N→P), and heat is released at the lower hot end (P→N). The connection of several pairs of thermocouples forms a thermopile. Placing the cold end of the thermopile in the circulating air duct 24 allows for heat absorption, thereby reducing the ambient temperature within the circulating air duct 24.

[0083] Combination Figure 10 and Figure 9 When the cold end of the thermopile of the second condensing device 23 is placed in the circulating air duct 24, it can replace the condensate of the first condensing device 25 and increase the condensation area through the cooling plate 232, and exchange heat with the humid and hot air in the circulating air duct 24. The liquefied humid and hot air carries away the heat to achieve drying. At the same time, the heat dissipation of the heat sink 232 can be achieved by the rotation of the cooling fan 233.

[0084] In one embodiment, when the controller 20 controls the second condensing device 23 to work, it can specifically control the cooling fan 233 of the second condensing device 23 to rotate, and the controller 20 can control the cooling fan 233 to rotate at different speeds.

[0085] In one embodiment, when the second condensing device 23 is working, the controller 20 can control the speed of the cooling fan to a first speed or a second speed based on at least one of the weight, humidity, or drying speed of the clothes in the inner drum 12, wherein the first speed is greater than the second speed. This allows the second condensing device 23 to achieve heat dissipation by using a faster speed when there is a large amount of heat to be dissipated, thereby reducing the time required for heat dissipation. Conversely, when the second condensing device 23 needs to dissipate less heat, the cooling fan speed can be reduced to decrease the energy consumption of the cooling fan and save costs.

[0086] Specifically, when the weight of the clothes in the inner drum is greater than a fourth preset value, the controller 20 controls the speed of the cooling fan 233 of the second condensing device 23 to a first speed. When the weight of the clothes in the inner drum 12 is less than or equal to the fourth preset value, the controller controls the speed of the cooling fan 233 of the second condensing device 23 to a second speed. When the humidity of the clothes in the inner drum 12 is greater than a fifth preset value, the controller controls the speed of the cooling fan 233 of the second condensing device 23 to a first speed. When the humidity of the clothes in the inner drum 12 is less than or equal to the fifth preset value, the controller controls the speed of the cooling fan 233 of the second condensing device 232 to a second speed. When the ratio of the dried time of the clothes in the inner drum 12 to the total drying time is greater than a sixth preset value, the controller controls the speed of the cooling fan 233 of the second condensing device 23 to a second speed. When the ratio of the dried time of the clothes in the inner drum 12 to the total drying time is less than or equal to the sixth preset value, the controller controls the speed of the cooling fan 233 of the second condensing device 23 to a first speed.

[0087] In one embodiment, the aforementioned fourth, fifth, and sixth preset values ​​may be specified, pre-configured, or user-set by the clothing processing device 1.

[0088] In one embodiment, the controller 20 can control the cooling fan 233 to rotate at different speeds based on a combination of conditions. For example, if the weight of the clothes in the inner drum 12 is greater than a fourth preset value and the humidity is greater than a fifth preset value, then the controller 20 will control the cooling fan 233 to rotate at the first speed. Furthermore, if the controller 20 controls the cooling fan 233 in conflicting ways, a certain priority can be set to achieve a more complete control logic. For example, if the priority is weight greater than humidity greater than drying progress, then if the weight of the clothes is greater than the fourth preset value and the humidity is less than the fifth preset value, the controller 20 will prioritize determining the cooling fan 233 to rotate at the second speed based on the weight of the clothes being greater than the fourth preset value, without considering the lower priority of humidity.
