DETAILED DESCRIPTION

[0039] 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.

[0040] The embodiment of the present application provides a drying system, which is applied to a clothes processing device, such as Figure 1-7 As shown, the drying system includes an outer drum 1 and an inner drum 2 and a drying air duct 3 connected between the outer drum 1 and the inner drum 2;

[0041] The drying air duct 3 is provided with a condensation air duct, and the condensation air duct is provided with a first condensation zone, which is formed on the inner side of the bottom wall of the outer cylinder 1 near the inner cylinder 2; a condensation water inlet is provided at the upper part of the first condensation zone for conveying condensed water into the first condensation zone;

[0042] The condensation air duct is further provided with a second condensation zone, which is formed on the outer side of the bottom wall of the outer tube 1 away from the inner tube 2. The bottom wall of the outer tube 1 is provided with a first air vent 4 and a second air vent 5, both of which are opened on the bottom wall of the outer tube 1, wherein the first air vent 4 is opened at the lower part of the bottom wall of the outer tube 1 for communicating the lower part of the first condensation zone with the lower part of the second condensation zone, and the second air vent 5 is opened at the upper part of the bottom wall of the outer tube 1 for communicating the upper part of the first condensation zone with the upper part of the second condensation zone;

[0043] The second condensation zone is rotatably provided with a water inlet 6, and the water inlet 6 is provided close to the second vent 5. The wall of the inner tube 2 is provided with a through hole 21 connecting the space of the inner tube 2 and the space of the outer tube 1;

[0044] The water inlet member 6 can be controlled to rotate and has at least a first working position and a second working position during the rotation process; in the first working position, the water flow sprayed by the water inlet member 6 can be sprayed toward the second condensation area to form a condensation effect on the drying air flow in the second condensation area; in the second working position, the water flow sprayed by the water inlet member 6 can be sprayed toward the inner side of the outer cylinder 1 and can flow into the inner cylinder 2 through the through hole.

[0045] In one embodiment, the drying duct 3 further comprises a volute duct and a heating duct. The inlet end of the volute duct is connected to the air outlet, and the outlet end is connected to the heating duct. The outlet end of the heating duct is in communication with the tube opening of the inner tube 2. A drying fan 14 is provided in the volute duct, and a heating device is provided on the heating duct. The drying duct 3 comprises a condensation box, which comprises a box body 7 and a cover 71. The box body 7 is arranged together with the outer wall surface of the bottom wall of the outer tube 1 or is integrally formed with the bottom wall of the outer tube 1. The cover 71 is provided on the box body 7 and forms the second condensation zone with the box body 7. The spray head is mounted on the box body 7 or the cover 71. The position of the spray head corresponds to the second vent, and the spray angle is adjustable.

[0046] In one embodiment, the water inlet member 6 is rotatably disposed in the second condensation zone. The water inlet member 6 can be rotatably disposed in the second condensation zone via a bearing, a flange, or other structure. Furthermore, a driving structure can be provided to drive the water inlet member 6 so that the water inlet member 6 is in the first working position or the second working position. This embodiment does not specifically limit this.

[0047] In one embodiment, the water inlet member 6 is used to spray water. Therefore, the water inlet member 6 can be a water pipe, a water valve, or a sprinkler valve. This embodiment does not limit the specific structure of the water inlet member 6. In addition, it should be noted that the water flow sprayed by the water inlet member 6 can be a continuous water flow, a water mist, water droplets, etc. The water flow in this application is only for ease of description and does not limit the shape and form of the sprayed water.

[0048] Through the above content, the second condensation area is provided with a first air vent 4 and a second air vent 5 connected with the first condensation area, and a water inlet 6 is provided at the second air vent 5. The water inlet 6 can rotate between a first working position and a second working position, so that during drying, the water flow sprayed by the water inlet 6 can provide condensed water for the second condensation area, so that the drying air flow can not only condense in the first condensation area, but also condense in the second condensation area, thereby improving the condensation efficiency and thus improving the drying efficiency; on the other hand, during care, the water inlet 6 can transport liquid into the inner drum 2 to humidify the clothes, facilitate the removal of wrinkles on the clothes and prevent the clothes from being damaged by the air flow with higher temperature, thereby improving the treatment effect of the clothes.

[0049] In another embodiment of the present application, the water inlet member 6 includes a mounting seat 8, a driving mechanism 9 and a spray head 10, the driving mechanism 9 is connected to the mounting seat 8, the driving mechanism 9 is used to drive the spray head to rotate relative to the mounting seat, and the mounting seat is fixed on the condensation air duct.

[0050] In one embodiment, the shape and volume of mounting seat 8 can be determined based on the space provided on the housing 7 or the space provided on the bottom wall of the outer tube 1. For example, if the housing 7 includes a rectangular mounting space, the shape and volume of mounting seat 8 can be designed to accommodate this rectangular mounting space. By inserting mounting seat 8 into this rectangular mounting space, mounting seat 8 snaps into place within the housing 7, securing mounting seat 8. For another example, if the housing 7 and the bottom wall of the outer tube 1 lack structures or spaces for mounting seat 8 to connect, mounting seat 8 can be connected to the housing 7 or the bottom wall of the outer tube 1 using screws or other structures. Therefore, this embodiment does not limit the shape, volume, or connection method of mounting seat 8.

[0051] In one embodiment, the driving mechanism 9 is a ring-shaped electric rotator. After the driving mechanism 9 is started, the output end of the driving mechanism 9 performs a circular motion around its rotation axis, and the central axis of the sprinkler head 10 coincides with the rotation axis, so that the sprinkler head 10 rotates following the output end of the driving mechanism 9.

[0052] As described above, the drive mechanism 9 is used to drive the spray head 10 to rotate, which is convenient and quick. At the same time, the spray head 10 is easy to spray water mist, which helps to improve the condensation efficiency of the second condensation zone and the care effect on clothes, and does not cause excessive humidity in the local area of ​​clothes.

[0053] In another embodiment of the present application, a limiting groove 11 is provided on the outer circumference of the shower head 10 , and a limiting column 12 for inserting into the limiting groove 11 is connected to the mounting seat 8 .

[0054] In one embodiment, the shower head 10 is provided with a mounting ring having a retaining groove 11 defined on its outer circumference. The mounting base 8 is provided with a retaining post 12 that can be retained within the retaining groove 11. The retaining post 12 slides with the retaining groove during rotation of the shower head. In another embodiment, the retaining groove 11 is defined directly on the outer circumference of the shower head 10, although this embodiment is not limited thereto. When the shower head 10 is connected to the output end of the drive mechanism 9, the retaining post 12 is positioned within the retaining groove 11. The angle or length of the retaining groove 11 is determined by the desired rotation angle of the shower head 10. For example, when the first and second working positions differ by 90 degrees, the retaining groove 11 can be a quarter-circle arc, such that when the retaining post 12 is located at the first end of the retaining groove 11, the shower head 10 is in the first working position, and when the retaining post 12 is located at the second end of the retaining groove 11, the shower head 10 is in the second working position.

[0055] According to the above content, the position of the sprinkler head 10 is easily controlled by providing the limiting groove 11 and the limiting column 12 , so that the rotation angle of the sprinkler head 10 is controllable, thereby improving the accuracy of the position of the sprinkler head 10 .

[0056] In another embodiment of the present application, the projection of the water inlet member 6 on the bottom wall of the outer cylinder 1 completely overlaps or partially overlaps with the second vent 5 .

[0057] In one embodiment, the projection of the water inlet member 6 partially overlaps with the second vent 5. That is, the position of the water inlet member 6 corresponds to the second vent 5, so that the liquid output by the water inlet member 64 can be sprayed directly into the second vent 5, and the liquid then passes through the second vent 5 to reach the inner drum 2. Because the inner drum 2 is provided with a plurality of through holes, some of the liquid will pass through the through holes into the inner drum 2 and come into contact with the clothes, thereby cooling the clothes or increasing the humidity of the clothes.

[0058] According to the above content, the position of the water inlet 6 is set at the second vent 5, which facilitates the water inlet 6 to transport liquid into the inner drum 2 to cool the clothes or increase the humidity of the clothes, which helps to improve the post-drying effect of the clothes.

[0059] In another embodiment of the present application, a reflective plate 13 is provided on the outer peripheral side of the second vent 5 in the second condensation zone, and the reflective plate 13 is used to reflect at least part of the condensed water ejected from the water inlet 6 into the second vent 5 .

[0060] In one embodiment, the reflective plate 13 is arc-shaped, and the bending direction is away from the water inlet part 6, so that the liquid sprayed from the water inlet part 6 is ejected by the reflective plate 13 and moves toward the inner drum 2, and then passes through the through holes on the inner drum 2 and enters the inner drum 2 to contact the clothes.

[0061] As described above, the reflector 13 is provided to deliver liquid sprayed from the water inlet 6 into the inner drum 2. This ensures that the water inlet 6 can supply liquid to the inner drum 2, improving the post-drying effect of the clothes. Furthermore, the water inlet 6 is less likely to block the second vent 5, ensuring smooth airflow in the second condensation zone.

[0062] In another embodiment of the present application, a plurality of guide ribs are provided on the box body 7 .

[0063] In another embodiment of the present application, the drying system is provided with a controller, and the controller controls the start-up and spraying angle of the water inlet part 6 according to the clothing processing program of the clothing processing equipment.

[0064] The present application also provides a method for treating clothes, which is applied to the drying system described above, and the method includes:

[0065] Controlling the start and rotation angle of the water inlet member 6 according to the laundry processing program of the laundry processing equipment;

[0066] The control of the start-up and rotation angle of the water inlet member 6 according to the laundry processing program of the laundry processing device includes:

[0067] When the clothes processing device runs a drying program, the water inlet element 6 is controlled to be in the first working position according to the drying process to spray to meet the drying program;

[0068] When the clothes treating device runs a care program, the water inlet member 6 is controlled to be in the second working position according to the care process so as to be able to spray in accordance with the care program.

[0069] In one embodiment, controlling the water inlet member 6 to be in the first working position to spray according to the drying process includes:

[0070] When the drying temperature exceeds a preset first threshold temperature, the water inlet component 6 is controlled to start at a preset first on / off frequency, so that the water inlet component 6 intermittently sprays condensed water into the second condensation area;

[0071] When the drying temperature exceeds a preset second threshold temperature, the water inlet component 6 is controlled to start at a preset second on / off frequency, so that the water inlet component 6 intermittently sprays condensed water to the second condensation zone;

[0072] The first threshold temperature is less than or equal to the second threshold temperature;

[0073] The first on-off frequency is less than or equal to the second on-off frequency

[0074] In one embodiment, the drying temperature can be acquired using a temperature sensing package in the clothes processing device, or a temperature sensor can be installed separately to acquire the temperature. Specifically, the drying temperature is the temperature of the drying airflow when it enters the inner drum, and the temperature sensing package or temperature sensor can be installed at the drying airflow inlet of the inner drum to acquire the temperature.

[0075] Through the above steps, the water inlet component 6 is controlled to start at different positions according to the operating program of the clothing processing equipment, so that the water inlet component 6 can spray condensed water into the second condensation zone during drying, and spray water mist into the inner drum 2 during care, thereby improving the treatment effect of the clothes.

[0076] Optionally, when the laundry treatment device runs a care program, the water inlet 6 is controlled to be in the second working position according to the care process so as to be able to spray to meet the care program, including:

[0077] Control the duration of the water inlet opening to a preset time threshold.

[0078] In one embodiment, the first threshold value T1 is less than the second threshold value T2, and the first threshold value and the second threshold value have the following relationship: 50°C ≤ T1 < 80°C ≤ T2 ≤ 100°C. The first on-off frequency F1 is preferably on for 35-50 seconds and off for 10-25 seconds; the second on-off frequency F2 is preferably on for 40-60 seconds and off for 0-20 seconds.

[0079] For ease of understanding, Figure 6 As shown, when the machine runs a drying program, the temperature of the drying airflow is initially increased. During this period, the drying airflow temperature T is measured. When T is greater than or equal to T1, the start and stop durations of the sprinkler head 10 are controlled using the F1 on / off ratio. When T is greater than or equal to T2, the start and stop durations of the sprinkler head 10 are controlled using the F2 on / off ratio. When drying is complete, the sprinkler head 10 is kept on to cool the interior of the machine.

[0080] When the whole machine runs a care program or a special washing program, the spray head 10 is controlled to rotate 90 degrees clockwise to the second working position to spray regularly. After the spraying is completed, the spray head 10 is controlled to rotate 90 degrees counterclockwise to the first working position to complete the care or special washing.

[0081] Optionally, before starting the water inlet member 6 located at the first working position according to the drying temperature control, the method further includes:

[0083] When the water inlet member 6 is located at the second working position, the control driving mechanism 9 drives the water inlet member 6 to rotate to the first working position;

[0084] Before controlling the water inlet member 6 located at the second working position to start, the method further includes:

[0085] The position of the water inlet member 6 is detected, and when the water inlet member 6 is located at the first working position, the driving mechanism 9 is controlled to drive the water inlet member 6 to rotate to the second working position.

[0086] In one embodiment, the position of the water inlet member 6 can be known based on the position of the output end of the driving mechanism 9, or the position of the limit column 12 can be acquired by sensors such as a camera and a radar.

[0087] An embodiment of the present application further provides a clothing processing device, comprising the above-mentioned drying system or being provided with the above-mentioned clothing processing method.

[0088] Optionally, the clothing processing device is a clothes dryer or a washer-dryer.

[0089] The serial numbers of the above-mentioned embodiments of the present application are for description only and do not represent the advantages or disadvantages of the embodiments.

[0090] In the above embodiments of the present application, the description of each embodiment has its own focus. For parts that are not described in detail in a certain embodiment, please refer to the relevant description of other embodiments.

[0091] 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.
