An exhaust fan is installed at the top of the through cavity, and a first air inlet is provided at the bottom of the through cavity. Heat dissipation fins are installed above the first air inlet in the through cavity. Air entering through the first air inlet passes through the heat dissipation fins and is then discharged from the through cavity by the exhaust fan. The heat dissipation fins include a front part and a rear part, both of which are arranged vertically. The front part has a through groove arranged vertically. A semiconductor cooling chip and a condensing fin are installed sequentially from back to front in the through groove. The semiconductor cooling chip has a heat insulation part arranged circumferentially.

[0009] In some embodiments, the heat dissipation fins have a recess at the lower end of the through groove, and the flow guide cup cooperates with the recess to accommodate the flow guide cup in the heat dissipation fins.

[0010] In some embodiments, the surface of the heat sink fins and the condenser fins is provided with a wave pattern, and the length direction of the wave pattern is set along the vertical direction.

[0011] In some embodiments, a gasket is provided on the rear side of the front sidewall of the housing. The gasket serves as a second baffle. The gasket and the front sidewall are provided with a second air inlet. The lower part of the gasket is provided with a downward-facing opening below the second air inlet.

Detailed Implementation

[0024] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The embodiments described below are merely examples, and other obvious variations will be apparent to those skilled in the art. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0025] Those skilled in the art should understand that in the disclosure of this utility model, the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as a limitation of this utility model.

[0026] like Figures 1 to 10 As shown, this disclosure proposes a dehumidifier, including a housing 1. In this example, the housing 1 includes a back plate 2 and a front shell 3. The front shell 3 and the back plate 2 are connected front and rear to form a complete housing 1. The front shell 3 is a rectangular shell and the back plate 2 is a rectangular plate. Therefore, the housing 1 is rectangular in shape as a whole.

[0027] The housing 1 has a through cavity extending vertically, which is the inner cavity of the housing 1. An exhaust fan 4 is installed at the top of the through cavity, and a first air inlet 5 is provided at the bottom of the through cavity. A heat dissipation fin 6 is installed above the first air inlet 5 inside the through cavity. The air entering through the first air inlet 5 passes through the heat dissipation fin 6 and is then discharged from the through cavity by the exhaust fan 4. The heat dissipation fin 6 includes a front part 7 and a rear part 8. The heat dissipation fins of both the front part 7 and the rear part 8 are oriented vertically. The front part 7 has a vertically oriented... A through groove 9 is provided, in which a thermoelectric cooler 10 and a condenser fin 11 are installed sequentially from back to front. A heat insulation part 12 is provided around the thermoelectric cooler 10, such as heat insulation cotton. The rear end of the thermoelectric cooler 10 is the hot end, and the front end of the thermoelectric cooler 10 is the cold end. The hot end is thermally connected to the bottom of the through groove 9, and the cold end is thermally connected to the condenser fin 11. The condenser fin 11 is fixedly connected to the through groove 9 to clamp the thermoelectric cooler 10 between the condenser fin 11 and the bottom of the through groove 9.

[0028] A first baffle 13 is provided at the top of the through groove 9 along the front-to-back direction, and a second baffle 14 is provided on the front side of the condenser fins 11 along the up-down direction. The second baffle 14 covers the through groove 9 to form an air flow channel. A gap 15 is formed between the first baffle 13 and the second baffle 14. A second air inlet 16 is provided on the second baffle 14 at the center and / or below the condenser fins 11. In this example, the second air inlet 16 is set approximately in the center relative to the condenser fins 11.

[0029] In some embodiments, such as Figure 3 , 4 As shown, a guide cup 17 is provided on the lower side of the condenser fin 11, and an opening is provided on the upper side of the guide cup 17. This opening is used to collect the condensate from the condenser fin 11 and to discharge the condensate through the guide port 18. The guide port 18 is configured as an interface and can be used to connect a guide pipe.

[0030] In some embodiments, such as Figure 3 , 4 As shown, the heat dissipation fins 6 have a recess 21 at the lower end of the through groove 9, and the flow guide cup 17 cooperates with the recess 21 to accommodate the flow guide cup 17 in the heat dissipation fins 6. In this way, the flow guide cup 17 is hidden, which is beneficial to the compact structure.

[0031] In some embodiments, such as Figure 4 , 5 As shown, the surfaces of the heat dissipation fins 6 and condenser fins 11 are both provided with corrugated patterns 19, with the length of the corrugated patterns 19 arranged along the vertical direction. This provides a larger exchange area, which is beneficial for improving the dehumidification effect.

[0032] In some embodiments, such as Figure 3 , 7As shown, a gasket is provided on the rear side of the front sidewall of the housing 1. This gasket serves as a second baffle 14. A second air inlet 16 is provided through the gasket and the front sidewall. The lower part of the gasket, located below the second air inlet 16, has a downward-facing opening 20. This opening 20 extends downward to connect with the first air inlet 5 and extends upward to connect with the through groove 9. In this way, a combined air intake is formed, that is, air is simultaneously drawn in from the first air inlet 5 and the second air inlet 16, so that more air is filled into the through groove 9, and then the condenser fins 11 perform condensation and dehumidification.

[0033] In some embodiments, such as Figure 7 As shown, in the case where the guide cup 17 mates with the recess 21, the recess 21 is located behind the opening 20, and the guide cup 17 is positioned lower than the gasket. This makes the channel from the first air inlet 5 to the through groove 9 wider, which is beneficial for air intake.

[0034] In some embodiments, such as Figure 3 As shown, a circuit board 22 is installed below the exhaust fan 4 in the through cavity. In this way, the condensed air first passes through the circuit board 22 and then is discharged through the exhaust fan 4, which plays a certain role in cooling the circuit board 22.

[0035] The circuit board 22 is used to supply power to the exhaust fan 4 and the semiconductor cooling chip 10 and to control their on / off states.

[0036] When understanding this disclosure, the above structure may be referred to other embodiments / appendices if necessary. Figure 1 And that is understood, so I will not elaborate further here.

[0037] The above description is merely an illustrative embodiment of this utility model. Therefore, all equivalent changes or modifications made to the structure, features, and principles described in the scope of protection of this utility model are included within the scope of protection of this utility model.
