[0036] 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.

[0037] like Figure 1-4 As shown, an embodiment of the present application provides a drying system, which is applied to a clothes processing device. The clothes processing device includes an inner drum 2 and an outer drum 1. The system includes a drying air duct formed between the inner drum 2 and the outer drum 1. The drying air duct includes a first condensing air duct 3, a second condensing air duct 4 and a fan air duct 5.

[0038] The first condensation air duct 3 is formed on a side of the outer tube 1 away from the inner tube 2, and includes a first air inlet 31 and a first air outlet;

[0039] The second condensation air duct 4 is formed between the outer tube 1 and the inner tube 2. The second condensation air duct 4 is provided with a second air outlet 41. The second air outlet 41 connects the second condensation air duct 4 with the first condensation air duct 3.

[0040] The first air inlet 31 and the second air outlet are arranged at different heights along the rear bottom of the outer tube 1, wherein the first air inlet 31 is arranged at the lower part of the rear bottom of the outer tube 1, and the second air outlet 41 is arranged at the upper part of the rear bottom of the outer tube 1; the first air outlet is located on the side wall of the first condensation air duct 3 and between the first air inlet 31 and the second air outlet 41;

[0041] The first air outlet is connected to the inlet of the fan duct 5; a heat dissipation device is provided on the outside of the duct wall of the first condensation duct 3, and the heat dissipation device is used to reduce the temperature of the duct wall.

[0042] In one embodiment, the clothes processing device further comprises a box body, and the outer tub 1 and the inner tub 2 are both installed inside the box body. Figure 5 and 6As shown, the front end of the box is provided with an opening for putting in clothes, and a door seal 17 is provided on the opening, and a glass bowl 18 is rotatably connected to the door seal 17. When the user uses the clothes processing device, he rotates the glass bowl 18 to separate the glass bowl 18 from the door seal 17, and then puts the clothes into the inner drum 2 through the opening. Figure 6 As shown, the side where the glass bowl 18 is provided is the front end of the box body, and the side opposite to the front end is the rear end. Based on this direction, the opening of the inner tub 2 faces the front end of the box body, and the surface of the inner tub 2 opposite to the opening is the rear bottom of the inner tub 2. The rear bottom of the inner tub 2 is vertically arranged in the clothing processing device. The rear bottom of the outer tub 1 is parallel to the rear bottom of the inner tub 2. For the sake of convenience in description, of the two surfaces of the rear bottom of the outer tub 1, the surface close to the inner tub 2 is called the inner bottom wall, that is, the bottom wall of the outer tub 1 on the inner side; the surface away from the inner tub 2 is called the outer bottom wall, that is, the bottom wall of the outer tub 1 on the outer side. For the sake of convenience in understanding, Figure 1 The perspective in the middle shows the outer bottom wall of the outer tube 1. Figure 3 The inner bottom wall of the outer tube 1 is seen from the perspective in the figure. The inner bottom wall is located between the outer tube 1 and the inner tube 2. Figure 2 For example, Figure 2 The upper side is the upper part of the rear bottom of the outer tube 1. Figure 2 The lower side is the lower part of the rear bottom of the outer tube 1.

[0043] In one embodiment, the drying system includes a first condensation duct 3, a second condensation duct 4, and a fan duct 5. Both the first condensation duct 3 and the second condensation duct 4 are used to circulate condensed water, condensing the dry airflow to reduce the humidity of the dry airflow. A heating device is installed in the fan duct 5 or in the drying system to heat the dry airflow. The heated dry airflow first enters the inner drum 2, where it comes into contact with the clothes, drying them and carrying moisture from the clothes into the outer drum 1. It should be noted that since the second condensation duct 4 is formed between the outer drum 1 and the inner drum 2, the connection point between the inner drum 2 and the outer drum 1 can be considered the air inlet of the second condensation duct 4. Due to the differences in the structures of different clothing processing devices, some inner drums 2 are provided with multiple through holes, through which the dry airflow in the inner drum 2 can pass into the outer drum 1 (i.e., into the second condensation duct 4); some clothing processing devices do not have through holes in the inner drum 2, but the inner drum 2 and the outer drum 1 are connected, and the dry airflow in the inner drum 2 enters the outer drum 1 through the connection point. That is to say, this embodiment does not limit the shape and position of the air inlet of the second condensation air duct 4 , nor does it limit the number of the air inlet of the second condensation air duct 4 .

[0044] Specifically, in one embodiment, the second condensation duct 4 refers to the space between the rear bottom of the inner tube 2 and the rear bottom of the outer tube 1. The condensed water flows downward along the inner side wall of the rear bottom of the outer tube 1 and comes into contact with the drying airflow in the second condensation duct 4 to achieve condensation.

[0045] After the drying airflow enters the outer drum 1, Figure 3 As shown, a part of the drying airflow flows upward along the second condensing air duct 4 and is finally discharged from the second air outlet 41; another part of the drying airflow enters the first air inlet 31 and enters the first condensing air duct 3 through the first air inlet 31. Figure 4 As shown, the dry airflow in the first condensing duct 3 flows upward along the duct wall of the first condensing duct 3, reaches the first air outlet, and then enters the fan duct 5 through the first air outlet. At the same time, the dry airflow discharged from the second air outlet 41 enters the upper part of the second condensing duct 4, passes through the first air outlet, and enters the fan duct 5. After being heated, the dry airflow in the fan duct 5 reenters the inner drum 2 to dry the clothes, thus completing the circulation.

[0046] like Figure 1 As shown, in one embodiment, a heat dissipation device is provided on the outside of the air duct wall of the first condensation air duct 3. In another embodiment, a heat dissipation device is provided on the outside of the air duct wall of the second condensation air duct 4. Since the second condensation air duct 4 is formed between the outer tube 1 and the inner tube 2, the outer bottom wall of the outer tube 1 is the outside of the air duct wall of the second condensation air duct 4, and the rear bottom of the outer tube 1 is the air duct wall of the second condensation air duct 4.

[0047] According to the above content, a heat dissipation device is provided on the outside of the air duct wall of the first condensation air duct 3. The heat dissipation device can reduce the temperature of the air duct wall. When the temperature of the condensed water in the first condensation air duct 3 is too high, the condensed water and the air duct wall can exchange heat to reduce the temperature of the condensed water, thereby improving the condensation efficiency of the condensed water and the drying airflow, thereby improving the drying efficiency.

[0048] In another embodiment of the present application, the heat dissipation surface area of ​​the heat dissipation device is adapted to the duct wall area of ​​the first condensation duct 3 .

[0049] It should be noted that since a heat dissipation device can also be set on the outside of the air duct wall of the second condensation air duct 4, in order to facilitate distinction, the heat dissipation device set on the outside of the air duct wall of the first condensation air duct 3 is named as the first heat dissipation device, and the heat dissipation device set on the outside of the air duct wall of the second condensation air duct 4 is named as the second heat dissipation device.

[0050] In addition, the first condensation air duct 3 and the second condensation air duct 4 may also share a heat dissipation device.

[0051] In one embodiment, the condensation efficiency of the first condensation duct 3 is greater than that of the second condensation duct 4. Specifically, there are many ways to improve the condensation efficiency, which are not specifically limited in this embodiment. For example, by increasing the diameters of the first air inlet 31 and the first air outlet, the amount of dry air entering the first condensation duct 3 is greater than that of the second condensation duct 4, thereby achieving the purpose of improving the condensation efficiency of the first condensation duct 3. The purpose of improving the condensation efficiency of the first condensation duct 3 can also be achieved by increasing the contact area between the condensed water and the dry air flow in the first condensation duct 3. For example, the condensed water in the second condensation duct 4 flows along the inner bottom wall of the outer cylinder 1 and only contacts the dry air flow on one side, while the condensed water in the first condensation duct 3 can flow without contacting the duct wall, and the entire circumference of the condensed water can contact the dry air flow.

[0052] When the condensation efficiency of the first condensation duct 3 is higher, the condensed water in the first condensation duct 3 absorbs more heat from the drying airflow, causing its temperature to rise. If the condensed water temperature is too high, the condensation efficiency will decrease. In this case, the first heat dissipation device can cool the duct walls of the first condensation duct 3. On the one hand, the condensed water in contact with the duct walls will exchange heat with them, lowering the condensed water temperature. On the other hand, the lowered duct wall temperature will affect the temperature inside the first condensation duct 3, further lowering the condensed water temperature.

[0053] In one embodiment, the heat dissipation surface area of ​​the first heat dissipation device is adapted to the duct wall area of ​​the first condensation duct 3, which means that when conditions permit, the duct wall area of ​​the first condensation duct 3 is made as close as possible to the heat dissipation surface area of ​​the first heat dissipation device, which helps to improve the heat dissipation capacity of the first heat dissipation device and improve the cooling effect of the duct wall of the first condensation duct 3.

[0054] In another embodiment of the present application, the first condensation duct includes a first condensation duct shell arranged on the bottom of the rear cylinder of the outer cylinder and a sealing cover arranged on the first condensation duct shell, the heat dissipation device is arranged on the sealing cover, and the heat dissipation surface extends from a position corresponding to the first air inlet to a position corresponding to the first air outlet.

[0055] That is, the shape / length of the heat dissipation surface of the first heat dissipation device is adapted to the shape / length of the duct wall of the first condensation duct 3 , which helps to improve the heat dissipation capacity of the first heat dissipation device and improve the cooling effect of the duct wall of the first condensation duct 3 .

[0056] In another embodiment of the present application, the heat dissipation device is a semiconductor radiator, and the hot end of the semiconductor radiator is in contact with the outer wall surface of the air duct wall.

[0057] Through the above content, the semiconductor radiator has good heat dissipation efficiency and heat dissipation effect, which helps to reduce the temperature of the air duct wall in a short time, thereby reducing the temperature of the condensed water and improving the drying efficiency.

[0058] In another embodiment of the present application, a temperature sensing package 21 is provided on the inner side of the air duct wall of the first condensation air duct 3 , and the temperature sensing package 21 is used to collect the temperature of the condensed water in the first condensation air duct 3 .

[0059] It should be noted that if the clothes processing device has a temperature sensing package 21 and the temperature sensing package 21 can be set inside the air duct wall of the first condensing air duct 3, the temperature sensing package 21 in the clothes processing device can be directly used. If the clothes processing device does not have a temperature sensing package 21, or the position of the temperature sensing package 21 in the clothes processing device is not easy to change, the temperature sensing package 21 can be additionally set inside the air duct wall of the first condensing air duct 3.

[0060] Through the above, the temperature sensing package 21 in the clothing processing device can be used to measure the temperature of the condensed water, reducing hardware costs and saving space occupied by the drying system, thereby improving space utilization. In addition, the temperature sensing package 21 can detect the temperature of the condensed water in the first condensation duct 3, facilitating the timely activation of the first heat dissipation device to dissipate heat, ensuring drying efficiency, and avoiding a decrease in drying efficiency due to excessively high condensed water temperature.

[0061] In another embodiment of the present application, the temperature sensing package 21 is further used to compare the temperature of the collected condensed water with a preset temperature threshold, and when the temperature of the condensed water exceeds the temperature threshold, output a signal to start the heat dissipation device.

[0062] The temperature sensor 21 can compare the collected temperature with the temperature threshold and output a signal when the temperature exceeds the threshold to activate the heat dissipation device, so that the drying system can automatically cool the condensed water and improve the drying efficiency.

[0063] In another embodiment of the present application, the diameter of the first air inlet 31 is greater than the diameter of the second air outlet 41 .

[0064] In one embodiment, by increasing the diameter of the first air inlet 31, the condensation efficiency of the first condensation duct 3 is increased to be greater than that of the second condensation duct 4. Combined with a first heat sink disposed on the duct wall of the first condensation duct 3, this facilitates controlling the temperature of the condensed water with higher condensation efficiency while controlling the number of heat sinks and space occupied, thereby improving drying efficiency.

[0065] In another embodiment of the present application, a condensate inlet joint 22 is installed on the upper part of the rear bottom of the outer tube 1, and the condensate inlet joint 22 is used to transport condensate to the second condensation air duct 4 and make the condensate in the second cooling air duct flow along the rear bottom of the outer tube 1; a plurality of guide strips 19 with different extension directions are provided on the rear bottom of the outer tube 1, and the guide strips 19 are used to change the flow direction of the condensate flowing in the second condensation air duct 4 along the rear bottom of the outer tube 1.

[0066] The condensed water can flow directly from the condensed water inlet joint 22 to the inner bottom wall of the outer tube 1, thereby condensing the drying airflow in the second condensation duct 4, which helps to ensure that the temperature of the condensed water in the second condensation duct 4 is not easily increased due to long-distance flow, thereby ensuring the condensation efficiency of the second condensation duct 4. In addition, the extension direction of the guide strip 19 is different, specifically as follows Figure 3 As shown, it is convenient to make the condensed water in the second condensing air duct 4 spread over the rear bottom of the outer cylinder 1 (that is, the inner bottom wall of the outer cylinder 1), increase the contact area between the drying airflow and the condensed water, and further improve the condensation efficiency of the second condensing air duct 4.

[0067] In another embodiment of the present application, the air duct wall of the first condensing air duct 3 is integrally formed with the outer cylinder 1;

[0068] The heat dissipation device is fixedly or detachably arranged on the wall of the air duct.

[0069] In one embodiment, the existing first condensing duct 3 is mostly fixed to the rear drum in the form of multiple parts spliced ​​together. In this embodiment, the duct wall of the first condensing duct 3 is integrally formed with the outer drum 1, which helps to reduce the space occupied by the drying system, thereby reducing the depth of the clothes processing equipment, while also improving sealing reliability and reducing costs.

[0070] The heat dissipation device can be fixedly connected to the air duct wall by gluing, or can be detachably set on the air duct wall by using structures such as snaps, so as to facilitate replacement and maintenance.

[0071] The present application also provides a clothes drying method, which is applied to the above-mentioned drying system. The drying method includes:

[0072] Obtaining the temperature of the condensed water in the first condensation air duct 3;

[0073] When the temperature of the condensed water in the first condensation air duct 3 exceeds a preset first temperature threshold, the heat dissipation device is started to lower the temperature of the air duct wall of the first condensation air duct 3 .

[0074] In one embodiment, the main body for executing the drying method can be the temperature sensing package 21 installed on the inner side of the air duct wall of the first condensation air duct 3, or it can be an additional controller, which is not limited in this embodiment of the present application.

[0075] The first temperature threshold and the second temperature threshold can be set according to actual conditions and are not specifically limited in this embodiment. For example, the first temperature threshold and the second temperature threshold can be the same or different. The first temperature threshold and the second temperature threshold can be a temperature value 3 degrees Celsius higher than the initial temperature of the condensed water, or can be a preset temperature value.

[0076] Through the above content, the duct wall is automatically cooled by detecting the temperature of the condensed water, which improves the automation level of the drying system, helps to cool the duct wall in time, and controls the temperature of the condensed water within a reasonable range, thereby ensuring the drying efficiency.

[0077] An embodiment of the present application also provides a clothing processing device, including the above-mentioned drying system.

[0078] In one embodiment, if Figure 5 and 6 As shown, the clothes processing device further includes an inner drum 2 and an outer drum 1. A collecting box 8 is provided at the lower end of the outer drum 1. The collecting box 8 is connected to both the first condensation duct 3 and the second condensation duct 4 for storing condensed water.

[0079] The collecting box 8 is connected to a water pump 9, the water inlet end of the water pump 9 is connected to the collecting box 8, the first water outlet end of the water pump 9 is connected to a multi-way connector 10, the water inlet end of the multi-way connector 10 is connected to the first water outlet end of the water pump 9, and the water outlet end of the multi-way connector 10 is connected to a first water pipe 11 and a second water pipe 12;

[0080] One end of the first water pipe 11 away from the water pump 9 extends to the second air outlet 41 , and one end of the second water pipe 12 away from the multi-way connector 10 extends to the first air inlet 31 ;

[0081] The second water outlet of the water pump 9 is connected to the third water pipe 13, the third water pipe 13 is connected to the water diversion valve 14, and the water outlet of the water diversion valve 14 is connected to the fourth water pipe 15 and the fifth water pipe 16 respectively;

[0082] The fourth water pipe 15 extends from one end of the water diversion valve 14 to the door seal 17 and the glass bowl 18 of the clothes processing device;

[0083] One end of the fifth water pipe 16 away from the water diversion valve 14 extends to the inner bottom wall of the outer tube 1 .

[0084] In one embodiment, the shape, volume and specific structure of the collecting box 8 are not limited in this embodiment. The collecting box 8 collects the condensed water, which is convenient for reuse of the condensed water and saves water resources.

[0085] In one embodiment, the water pump 9 can pump condensed water from the collection box 8 and supply it to the first water pipe 11. A first filter is provided at the first air inlet 31, and a second filter is provided at the second air outlet 41. The end of the first water pipe 11, away from the water pump 9, extends to the second filter. This allows the condensed water in the first water pipe 11 to flush and clean the second filter, preventing or resolving clogging issues.

[0086] Specifically, in one application scenario, the end of the first water pipe 11, away from the water pump 9, extends to the second filter and is connected to a spray device, which is used to clean the second filter. The provision of the second water pipe 12 improves the utilization rate of the condensed books in the collection box 8 and conserves resources. Simultaneously, the condensed water in the second water pipe 12 can flush the first filter, eliminating the problem of clogging the first filter and ensuring drying efficiency.

[0087] In one embodiment, the fourth water pipe 15 and the fifth water pipe 16 can both be connected to a spray device to rinse the door seal 17 and the glass bowl 18, so as to rationally utilize the condensed water in the collection box 8, improve utilization rate, and save resources.
