[0034] like Figure 1-8 As shown, the present invention is a refrigeration and dehumidification module, including a main housing 100. The inner wall of the main housing 100 has an integrally connected mounting plate 101, which divides the inner cavity of the main housing 100 into a condensate collection chamber 107 and an air exhaust chamber 108.

[0035] The mounting plate 101 is provided with a vent hole 103 to enable communication between the condensate collection chamber 107 and the air exhaust chamber 108.

[0036] like Figure 2 , Figure 6As shown, the mounting plate 101 has a through hole in the middle, and the cooling element 120 is disposed in the through hole. The cooling side (usually the cold end) of the cooling element 120 is fitted to the condensing structure 110, and the heating side (hot end) of the cooling element 120 is fitted to the heat dissipation structure 130. The condensing structure 110 is installed in the condensate collection chamber 107, and the heat dissipation structure 130 is installed in the air exhaust chamber 108. The condensing structure 110 includes a condensing base plate 111, on one side of which several parallel condensing fins 112 are evenly distributed. The lugs at both ends of the condensing base plate 111 are fixedly connected to the mounting plate 101. To facilitate positioning, the upper surface of the mounting plate 101 is provided with a positioning angle 104, which cooperates with the condensing base plate 111 to achieve rapid positioning.

[0037] The heat dissipation structure 130 includes a heat sink 131 and multiple heat dissipation fins 132 disposed on the heat sink 131. A fan assembly is disposed below the heat dissipation structure 130, including a fan bracket 140 and a cooling fan 150. The bottom surface of the mounting plate 101 has a vertically downward extending bracket limiting plate 105 and a bracket connecting seat 106. The fan bracket 140 is positioned by the bracket limiting plate 105 and is fastened to the bracket connecting seat 106 with screws. The fan bracket 140 is frame-shaped, with a U-shaped positioning groove 142 at its upper end and a vertically downward extending positioning post 141 on its bottom surface. The fan bracket 140 has clips 143 on both inner walls corresponding to the U-shaped positioning groove, and the groove opening corresponds to an exhaust port 109.

[0038] The cooling fan 150 includes an upper panel 152, a lower panel 153 arranged parallel to each other, and a fan connecting part 154 for connecting the upper panel 152 and the lower panel 153. The upper panel 152 and the lower panel 153 are symmetrically arranged, and positioning holes 151 are respectively provided at the four corners of the upper panel 152 and the lower panel 153. During assembly, the positioning holes 151 cooperate with the positioning pins 141 to achieve pre-positioning, and the upper panel 152 is fastened and fixed by the buckles 143, thereby making the cooling fan 150 stably installed in the fan bracket 140.

[0039] A housing cover 160 is fixedly connected to the open end of the air exhaust chamber 108. The housing cover 160 includes a base plate 161, and a vertically extending upright plate 162 is provided on one side of the base plate 161. The upper end of the upright plate 162 extends to the bottom surface of the fan bracket 140, providing auxiliary support for the fan assembly.

[0040] A positioning frame 163 is vertically provided on the upper surface of the base plate 161. The positioning frame 163 is U-shaped, and the upright plate 162 is located at the open end of the positioning frame 163. The positioning frame 163 is positioned and fitted into the inner wall of the main housing 100 to ensure the accurate installation position of the housing cover 160. The connecting lug on the outer surface of the housing cover 160 is fixedly connected to the bolt seat on the main housing 100 by screws.

[0041] The outer end of the condensate collection chamber 107 is provided with an air inlet hood 170 and a water collection tank 180. The air inlet hood 170 is used to connect with the exhaust pipe of the dryer to guide high-temperature and high-humidity air into the condensate collection chamber 107. The water collection tank 180 is movably disposed at the bottom of the condensate collection chamber 107 for collecting condensate.

[0042] The working principle of this invention is as follows: During operation, when the invention is started, the cooling chip 120 operates, cooling the condensing structure 110 on its cooling side and heating the heat dissipation structure 130 on its heating side. The high-temperature and high-humidity air discharged from the dryer enters the condensate collection chamber 107 through the air inlet hood 170, and comes into contact with the low-temperature condensing fins 112. The water vapor in the air quickly condenses into water droplets, which adhere to the surface of the condensing fins 112 and drip down into the water collection tank 180. The dehumidified dry air enters the air exhaust chamber 108 through the vent 103 on the mounting plate 101, where it exchanges heat with the heat dissipation structure 130. The cold air flowing in from the cold side comes into full contact with the heat dissipation fins 132 and is then discharged into the room through the exhaust port 109 via the cooling fan 150. Since most of the moisture in the high-temperature and high-humidity air has been condensed and removed, the discharged air has a lower temperature and lower humidity, thereby effectively improving the indoor environment.

[0043] like Figure 9-12 As shown, this application also provides a clothes dryer, including the aforementioned refrigeration and dehumidification module. The refrigeration and dehumidification module is configured in the clothes dryer 200 and can dehumidify the high-temperature, high-humidity air discharged from the clothes dryer 200. Under the above overall conceptual framework, specific implementation methods are divided into two main directions: The first direction involves a sealed connection between the air inlet shroud 170 of the refrigeration and dehumidification module and the air outlet 210 of the clothes dryer, directly dehumidifying the high-temperature, high-humidity air discharged from the clothes dryer 200; the second direction involves the air inlet shroud 170 of the refrigeration and dehumidification module being installed on the rear cover 230 of the clothes dryer 200. In use, the refrigeration and dehumidification module can be selected to work synchronously with the clothes dryer 200, i.e., drying and dehumidification operate simultaneously, or the dehumidification and drying operations of the refrigeration and dehumidification module can be selected to operate independently. When drying is not required and only dehumidification is desired, the refrigeration and dehumidification module can be activated independently to dehumidify the room.

[0044] Specifically, regarding the scheme where the high-temperature, high-humidity air discharged from the dryer's outlet 210 directly acts on the refrigeration and dehumidification module, this application provides the following two design schemes: First, the air inlet shroud 170 and the outlet 210 are sealed together via a connecting sleeve 220. One axial end of the connecting sleeve 220 has a first connecting seat 221, and the other axial end has a second connecting seat 222. The first connecting seat 221 is fitted onto the cylindrical outlet 210, and the first connecting seat 221 is bolted to the connecting hole on the outside of the outlet 210. The second connecting seat 222 is bolted to the connecting hole on the air inlet shroud 170. In practice, to avoid interference, the first connecting seat 221 and the second connecting seat 222 are usually arranged perpendicularly.

[0045] 2. The air inlet hood 170 and the air outlet 210 are sealed together by a connecting pipe 240. The refrigeration and dehumidification module is fixed to the dryer 200 housing by a support 250. The exhaust port 109 of the refrigeration and dehumidification module exhausts air from the bottom of the dryer 200. In this design, the connecting pipe 240 is sealed inside the dryer 200 housing by a rear cover 230.

[0046] In addition to directly connecting the refrigeration and dehumidification module to the air outlet 210 of the dryer 200, the refrigeration and dehumidification module can also be installed on the rear cover 230 of the dryer 200. The air inlet hood 170 and the water collection tank 180 of the refrigeration and dehumidification module correspond to one side of the rear cover 230, and the exhaust port 109 of the refrigeration and dehumidification module exhausts from the bottom of the dryer 200. In this case, the refrigeration and dehumidification module can operate synchronously with the dryer 200 or operate independently to dehumidify the room. The water collection tank 180 can be pulled out relative to the rear cover of the dryer, making it convenient for users to regularly clean the collected condensate. To facilitate the pulling out of the water collection tank 180, a handle is provided on the outer end face of the water collection tank 180.

[0047] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solutions of the present invention and not to limit it. Although the present invention has been described in detail with reference to examples, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
