[0022] Figure 1 This is a front sectional view of a hot and cold air switching mechanism for a dryer according to an embodiment of the present invention.

[0023] Figure 2 This is a schematic diagram of the front cross-sectional structure of a dryer according to an embodiment of the present utility model. Detailed Implementation

[0024] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, further illustrating the present invention.

[0025] First, combine Figure 1 This invention describes a hot and cold air switching mechanism for a dryer according to an embodiment of the present invention, which is used for switching between hot and cold air delivery and has a wide range of applications.

[0026] like Figure 1 As shown, a hot and cold air switching mechanism for a dryer according to an embodiment of the present invention includes a housing 100, a first inlet 200, a second inlet 300, an outlet 400, a heating unit 500, and a sealing assembly.

[0027] Specifically, such as Figure 1 As shown, the first inlet 200 is located at the top of the housing 100 for air intake.

[0028] Specifically, such as Figure 1 As shown, the second inlet 300 is located at the bottom of one side of the housing 100 for air intake.

[0029] Specifically, such as Figure 1 As shown, outlet 400 is located at the bottom of housing 100 and is connected to the air inlet of an external dryer for delivering hot or cold air to the external dryer.

[0030] Specifically, such as Figure 1 As shown, the heating unit 500 is installed on the housing 100 and is used to heat the air that enters through the first inlet 200. Then, the heated air (i.e., hot air) is delivered to the outside dryer through the outlet 400 to heat and dry the clothes inside the dryer. The heating unit 500 is a steam coil heating unit 500.

[0031] Specifically, such as Figure 1 As shown, a sealing assembly is disposed on one side of the housing 100 for sealing the first inlet 200 or the second inlet 300. The sealing assembly includes a sealing plate 601, a mounting base 602, and a telescopic device 603. The sealing plate 601 is hinged to the top of one side of the housing 100. The sealing plate 601 has a first sealing area 6011 and a second sealing area 6012. The first sealing area 6011 is used to seal the first inlet 200, and the second sealing area 6012 is used to seal the second inlet 300. The mounting base 602 is disposed on an external dryer. The fixed end of the telescopic device 603 is hinged to the mounting base 602, and the output end of the telescopic device 603 is hinged to the sealing plate 601. The telescopic device 603 is a cylinder. By controlling the operation of the expansion joint 603, the sealing plate 601 can move around the hinge, thereby allowing the first sealing area 6011 to seal the first inlet 200 and connect the outside air to the outlet 400 through the second inlet 300 to deliver cold air (i.e., unheated air); or the second sealing area 6012 can seal the second inlet 300 and connect the outside air to the outlet 400 through the first inlet 200 to deliver hot air (i.e., air heated by the heating unit 500).

[0032] Furthermore, such as Figure 1 As shown, a first sealing gasket 604 is provided at the first sealing area 6011 to improve sealing performance.

[0033] Furthermore, such as Figure 1 As shown, a second sealing gasket 605 is provided at the second sealing area 6012 to improve sealing performance.

[0034] Furthermore, such as Figure 1 As shown, the hot and cold air switching mechanism of a dryer according to an embodiment of the present invention further includes: an air guide plate 606, which is opened on the top of the second inlet 300 and can guide the air entering through the second inlet 300.

[0035] Working principle:

[0036] When hot air is needed, the second sealing area 6012 seals the second inlet 300, and the outside air is connected to the outlet 400 through the first inlet 200. The fan inside the dryer runs, and the outside air comes into contact with the heating unit 500 through the first inlet 200. The heating unit 500 heats the air, and the heated air is discharged into the dryer through the outlet 400 to heat the clothes.

[0037] After heating is complete, when cold air is needed, the first sealing area 6011 seals the first inlet 200, and the outside air is connected to the outlet 400 through the second inlet 300. The fan inside the dryer runs, and the outside air is transported through the second inlet 300 and discharged into the dryer through the outlet 400 to cool the clothes.

[0038] As described above, in the hot and cold air switching mechanism of a dryer according to an embodiment of the present invention, the dryer automatically switches to cooling mode after the drying stage is completed. It achieves rapid cooling by continuously supplying room temperature airflow, ensuring that users can handle clothes at a safe temperature. This temperature regulation mechanism ensures both drying efficiency and operational safety.

[0039] The above combined with the appendix Figure 1 A hot and cold air switching mechanism for a dryer according to an embodiment of the present invention is described. Furthermore, the present invention can also be applied to dryers.

[0040] like Figure 2 As shown, according to another embodiment of the present invention, a dryer is provided, which includes a hot and cold air switching mechanism 1 of the dryer of the previous embodiment, which can introduce hot air or cold air into the clothes in the dryer as needed.
