[0091] Preferably, such as Figures 6 to 9As shown, the number of dampers 72 is multiple, and the multiple dampers 72 are independent, and the multiple dampers 72 jointly shield the air outlet of the air blower 5.

[0092] As shown, when the damper 72 is in the closed state, Figure 9 As shown, preferably, the two adjacent dampers 72 have an overlapping part, so that the air outlet of the air blower 5 can be better shielded.

[0093] It should be noted that if the damper 72 is electric, as shown, Figure 6 As shown, preferably, each damper 72 is provided with a motor 73, and each damper 72 can be independently opened by the motor 73. For example, the number of dampers 72 is four, and the number of motors 73 is also four, and the four motors 73 independently drive the four dampers 72.

[0094] As shown, preferably, Figures 6 to 11 As shown, the damper 72 is provided with a limiting structure, and the limiting structure abuts against the fixed plate 71 after the damper 72 is opened to limit the damper 72 at a set opening position.

[0095] By limiting the damper 72 at the set opening position through the limiting structure, the opening angle of the damper 72 can be limited, so as to avoid that the opening angle of the damper 72 is too large to cause the airflow discharged from the air outlet of the air blower 5 to be greatly scattered, and in addition, for the wind type damper, by limiting the damper 72 at the set opening position through the limiting structure, the situation that the damper 72 cannot be closed by its own gravity because the opening angle of the damper 72 is too large can be avoided.

[0096] As shown, preferably, Figure 8 As shown, the multiple dampers 72 are parallel to each other when they are at the set opening position, and a wind guide channel is formed between the two adjacent dampers 72, and the wind guide channel is directed to the air outlet 61, that is, to the inner bottom of the drum 2.

[0097] After the damper 72 is opened, each damper 72 is limited at the set opening position by the respective limiting structure, and a wind guide channel is formed between the two adjacent dampers 72, and the airflow discharged from the air outlet of the air blower 5 flows along the wind guide channel to the air outlet 61 on the fixed member 6, and then flows to the inner bottom of the drum 2 after passing through the air outlet 61, so as to more effectively prevent the airflow from being scattered, and make the wind force stronger.

[0098] As shown, preferably, Figures 6 to 11 As shown, the damper 72 comprises a plate-shaped body 721 and a rotating shaft 722 provided on the plate-shaped body 721, the rotating shaft 722 is pivotally connected with the fixed plate 71, and the limiting structure is arranged on the rotating shaft 722.

[0099] Exemplarily, a plurality of clamping grooves 711 are arranged on the fixing plate 71, and each of the two sides of the plate-shaped body 721 of the air door 72 is provided with a rotating shaft 722, each rotating shaft 722 is rotationally connected with a corresponding clamping groove 711, when the air door 72 is opened, the limiting structure rotates along with the rotating shaft 722, when the limiting structure abuts against the fixing plate 71, the rotating shaft 722 is prevented from continuing to rotate, thereby limiting the air door 72 at a set opening position, and the plurality of plate-shaped bodies 721 are arranged in parallel, and a wind guiding channel is formed between two adjacent plate-shaped bodies 721.

[0100] It should be noted that the shape of the plate-shaped body 721 of each air door 72 can be the same or different, and preferably, the shape of the plate-shaped body 721 of each air door 72 is arranged according to the shape of the air outlet of the air blower 5.

[0101] For example, if the shape of the air outlet is square, the shape of the plate-shaped body 721 of each air door 72 can be arranged to be the same, and if the shape of the air outlet is circular, the shape of the plate-shaped body 721 of each air door 72 is preferably matched with the shape of the air outlet at the mounting position of the air door 72.

[0102] In addition, it should be noted that the specific structure of the limiting structure is not limited in the utility model, for example, the limiting structure can be arranged as a limiting block, a limiting plate or a limiting column, etc.

[0103] Preferably, as shown in Figures 6 to 11 the limiting structure is a limiting block 723, and the limiting block 723 has a stop surface 7231, and when the air door 72 is opened to a set opening position, the stop surface 7231 abuts against the fixing plate 71.

[0104] Exemplarily, the shape of the limiting block 723 is approximately sector-shaped, and the end surface of the top of the limiting block 723 is the stop surface 7231.

[0105] Preferably, the limiting block 723 is provided with a hollow structure (not shown in the figure), and the hollow structure is arranged close to the stop surface 7231.

[0106] By arranging the hollow structure close to the stop surface 7231, the weight of the lower part of the limiting block 723 is greater than that of the upper part, which is more conducive to closing the air door 72 by relying on its own gravity.
