DETAILED DESCRIPTION

[0024] The present invention is further described in detail below in conjunction with the embodiments:

[0025] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0026] like Figures 1 to 7 As shown, a hot air recovery device for a clothes dryer comprises: a dryer body 1, one side of the dryer body 1 is connected to an air inlet pipe 2, and the other side is connected to an air outlet pipe 3, the dryer body 1 is connected to a recovery structure 4, the recovery structure 4 comprises a recovery box 41 connected to the top of the dryer body 1, the input end of the recovery box 41 is connected to the air outlet pipe 3, the output end of the recovery box 41 is connected to the air inlet pipe 2, and a filter component 42 capable of filtering hot air impurities passing through the recovery box 41 is provided near the input end and the output end of the recovery box 41, and the recovery box 41 is also provided with a filter component 42 capable of filtering hot air impurities passing through the recovery box 41 relative to the recovery box 41. A condensation component 43 is rotated to condense water vapor in the hot air, and a water collecting tank 411 is also provided at the bottom of the recovery box 41. The recovery box 41 is also provided with a cover plate 412 capable of closing the water collecting tank 411, and a water leakage hole 4121 is provided on the cover plate 412. An opening groove 4122 capable of allowing debris to enter the water collecting tank 411 is also provided on the cover plate 412 and below the first filter component 42. A vibration component 44 is provided in the recovery box 41, which can make the filter component 42 move so that the debris accumulated on the filter component 42 falls off and enters the water collecting tank 411 through the opening groove 4122.

[0027] When the utility model is in use, clothes are dried through the dryer body 1, and the hot air generated by the dryer body 1 gradually moves to the input end of the recovery box 41 through the air outlet pipe 3, and the hot air first passes through the filter component 42 located at the input end of the recovery box 41, which can effectively filter out the floating particles mixed in the hot air, and the hot air filtered by the filter component 42 gradually contacts the condensation component 43 for condensation and dehydration, which can remove the moisture contained in the humid hot air to the maximum extent, and ensure the dryness of the circulating hot air, and the hot air passing through the condensation component 4 continues to flow out to the output end of the recovery box 41, and the hot air passes here The filter component 42 further filters to further reduce the debris contained in the hot air. The water condensed by the condensation component 43 enters the water collecting tank 411 through the leakage hole 4121, which is convenient for accumulating condensed water. After the device has been used for a period of time, the filter component 42 is vibrated by the vibration component 44. The debris particles on the filter component 42 gradually fall into the open groove 4122 under the action of their own weight and vibration, and enter the water collecting tank 411. The service personnel can easily clean the filter component 42 to avoid clogging of the filter component 42 and affecting the drying of the hot air, which is more convenient to use.

[0028] like Figures 4 to 6 As shown, the recovery box 41 is provided with a connecting frame 413, and the connecting frame 413 is provided with a movable groove 4131 in which the first filter component 42 can move, and the first filter component 42 includes an inner frame 421 movably connected to the movable groove 4131, and the inner frame 421 is connected to a filter plate 422, and the filter plate 422 is provided with a plurality of inclined filter holes, and a filter core is connected to the filter holes. The air permeability of the filter core is poor, which can slow down the flow rate of the hot air, so that the hot air passing through the first filter component 42 can fully contact the condensation component 43, condense water more fully, and improve the dehydration efficiency. The setting of the movable groove 4131 facilitates the movement of the inner frame 421.

[0029] like Figures 4 to 6As shown, the vibration assembly 44 includes a first connecting bracket 441 connected to one side of the inner frame 421 and a second connecting bracket 442 spaced apart from the first connecting bracket 441, the first connecting bracket 441 is provided with a plurality of first connecting parts 4411 protruding outward, the second connecting bracket 442 is provided with a plurality of second connecting parts 4421 protruding outward, an elastic member 443 capable of connecting the first connecting part 4411 and the second connecting part 4421 is provided between each of the first connecting parts 4411 and the second connecting parts 4421, and the outer peripheral surface of the inner frame 421 is also provided with an operating part 4211 capable of extending out of the recovery box 41. The service personnel operates the operating part 4211, and the operating part 4211 drives the inner frame 421 to move. When the inner frame 421 moves, the second connecting part 4421 on the inner frame 421 contacts and collides with the inner side surface of the connecting frame 413, and the elastic member 443 is compressed and deformed by the force. Since the first connecting bracket 441 and the second connecting bracket 442 have no direct contact, when the second connecting part 4421 collides with the inner side surface of the connecting frame 413, the elastic member 443 transmits force to the first connecting bracket 441, causing the inner frame 421 to shake, and then the operating part 4211 is released, and the elastic member 443 is reset. The inner frame 421 also shakes during the process of moving and resetting. Since the filter hole is set at an angle, under the action of gravity, the particulate debris accumulated at the filter hole mouth can be vibrated out of the filter hole mouth and fall into the opening groove 4122, thereby entering the water collection tank 411.

[0030] like Figure 2 As shown, the operating part 4211 is a convex column, and the recovery box 41 is provided with a guide slot 414 for the convex column to slide. The guide slot 414 is a bar-shaped slot for guiding the sliding of the operating part 4211.

[0031] like Figure 2 As shown, the operating part 4211 is also connected to a driving assembly 5, and the driving assembly 5 includes a mounting bracket 51 connected to the recycling box 41, and the mounting bracket 51 is connected to a first driving motor 52, and the output shaft of the first driving motor 52 is connected to a turntable 53, and the turntable 53 is movably connected to a sliding member 54 that can follow the movement of the turntable 53 and slide back and forth relative to the turntable 53, and the sliding member 54 will push the operating part 4211 to slide when sliding back and forth. When in use, the first driving motor 52 is started, and the first driving motor 52 drives the turntable 53 to rotate, and when the turntable 53 rotates, it drives the sliding member 54 to slide back and forth relative to the turntable 53, and the sliding member 54 pushes the operating part 4211 at a certain frequency, so that the inner frame 421 vibrates, which is convenient for discharging the debris in the filter hole.

[0032] like Figure 2As shown, the rotating disk 53 is provided with a protrusion 531 which is arranged away from the axis of the rotating disk 53, and the sliding member 54 is provided with a bar hole 541 in which the protrusion 531 can move. The provision of the bar hole 541 facilitates the insertion of the protrusion 531, and the protrusion 531 moves in the bar hole 541 when the rotating disk 53 rotates, and presses against the groove wall of the bar hole 541 so that the sliding member 54 can slide back and forth, and push the operating part 4211 of the inner frame 421, so that the frequency of vibration of the inner frame 421 is increased, and it is more convenient to discharge the debris in the filter hole.

[0033] like Figure 4 and Figure 7 As shown, the condensation assembly 43 includes a rotating shaft 431 that is rotatably connected to the recovery box 41 and extends into the recovery box 41. A plurality of support rods 432 are arranged around the outer periphery of the rotating shaft 431. The ends of the plurality of support rods 432 are connected to water collecting plates 433. A rotating motor 434 is connected to the rotating shaft 431. The rotating motor 434 is started to drive the rotating shaft 431 to rotate. When the rotating shaft 431 rotates, the support rods 432 and the water collecting plates 433 are driven to rotate. When the water collecting plates 433 rotate, the contact frequency with the water vapor in the hot air is increased, so that the water collecting efficiency of the water collecting plates 433 is improved.

[0034] like Figure 7 As shown, the water collecting plate 433 includes a first connecting piece 4331 connected to the ends of multiple support rods 432 and a second connecting piece 4332 connected to the other end of the first connecting part 4411. The first connecting piece 4331 and the second connecting piece 4332 are inclined to each other. Such an arrangement enables the first connecting piece 4331 and the second connecting piece 4332 to have a larger contact range with the water vapor in the hot air, making it easier to collect the water vapor in the hot air, so that the hot air can be sent into the dryer body 1 again after being recovered by the recovery box 41, thereby saving costs and improving the heating efficiency.

[0035] like Figure 7 As shown, the first connecting piece 4331 and the second connecting piece 4332 are connected with activated carbon sheets. The activated carbon sheets are convenient for absorbing water, and when the clothes are dried, the dryer body 1 can be turned on again to dry the activated carbon sheets, so that the activated carbon sheets can be reused, saving costs.

[0036] like Figure 1 As shown, the recovery box 41 is also provided with a drain pipe 415 capable of discharging the liquid in the water collecting tank 411, so that the drain pipe 415 can discharge water and debris.

[0037] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
