outer wind zones

22 and 23 of fig. 2, with the damper 25 in an open state. Fig. 5 is a sectional view of the dryer corresponding to the state of fig. 4.

Referring to fig. 3 to 5, in some embodiments, a plurality of second air inlets 142 may also be arranged at intervals in the top area of the back plate 14 corresponding to the outer wind area 23. When the inner tub 12 rotates relative to the outer tub 13, the hot air in the air duct 2 can be supplied to the top area of the clothes drying chamber 10 through the second air inlet 142, and the clothes attached to the peripheral wall of the inner tub 12 can be uniformly dried. And the layout design of the second air inlet 142 can concentrate the wind power in the outer wind area 23, improve the wind speed entering the clothes drying chamber 10 and realize the utilization rate of the hot wind energy in the outer wind area 23.

In some embodiments, the air duct 2 is disposed below the inner barrel 12, and the air return opening 201 is opened at the bottom of the peripheral wall of the front end of the inner barrel 12. The hot air in the air duct 2 can be supplied to the top area of the drying chamber 10 through the second air inlet 142, and then returns to the air duct 2 through the front end of the inner tub 12, i.e., the air return opening 201 at the bottom of the drying chamber 10, so that the air in the drying chamber 10 can flow sufficiently.

It can be understood that a plurality of first air inlets 141 may also be arranged at intervals in the top area of the back plate 14 corresponding to the inner wind region 22, and cooperate with the inner tub 12 to rotate relative to the outer tub 13, so as to improve the utilization rate of the hot wind energy in the inner wind region 22.

Referring to fig. 3 and 4, the fan 21 is disposed in the air duct 2 and around the outer wind area 23, and the air outlet 211 of the fan 21 can be respectively communicated with the outer wind area 23 and the inner wind area 22, so that the fan 21 can respectively supply air to the outer wind area 23 and the inner wind area 22, and respectively supply hot air to the clothes drying chamber 10 through the outer wind area 23 and the inner wind area 22.

In some embodiments, the air outlet 211 of the fan 21 is opposite to the peripheral sides of the outer wind zone 23 and the inner wind zone 22, and the peripheral wall of the inner wind zone 22 is provided with a damper 25 opposite to the air outlet 211 of the fan 21. The damper 25 is used for opening and closing the inner wind area 22 to control the on-off between the air outlet 211 of the fan 21 and the inner wind area 22. The damper 25 may be pivotally mounted to the inner wind zone 22 in an articulated manner.

Referring to fig. 4 and 5, when the damper 25 is opened, under the action of the wind of the fan 21, the hot wind in the wind channel 2 can directly enter the outside air zone 23 through the wind outlet 211 of the fan 21, and is blown to the peripheral side region of the clothes drying chamber 10 through the second wind inlet 142 in the outside air zone 23. Meanwhile, the hot air in the air duct 2 can enter the inner air area 22 through the air outlet 211 of the fan 21 and the air door 25, and is supplied to the central area of the clothes drying chamber 10 through the first air inlet 141 in the inner air area 22.

Therefore, in the state that the air door 25 is opened, the hot air delivered by the fan 21 can simultaneously enter the inner air area 22 and the outer air area 23, so that the first air inlet 141 and the second air inlet 142 on the back plate 14 can simultaneously ventilate, the hot air can be uniformly delivered in the whole space of the clothes drying chamber 10, and the clothes in the clothes drying chamber 10 can be uniformly dried. Therefore, when there are many clothes in the clothes drying chamber 10, the clothes drying can be performed by using this mode, which is beneficial to improving the clothes drying efficiency and ensuring the clothes drying effect.

Fig. 6 is a schematic view of the inner and

outer wind zones

22 and 23 of fig. 2, with the damper 25 in a closed state. Fig. 7 is a sectional view of the dryer corresponding to the state of fig. 6.

Referring to fig. 4 and 5, when the damper 25 is closed, the inner air zone 22 is closed, and the hot air in the air duct 2 can only enter the outer air zone 23 through the air outlet 211 of the fan 21, but cannot enter the inner air zone 22. Therefore, the hot air in the air duct 2 can only be supplied to the peripheral area of the clothes drying chamber 10 through the second air inlet 142 in the external air area 23, so as to achieve the effect of drying the clothes on the inner wall of the clothes drying chamber 10. Or the second air outlet 211 can only supply air to the top area of the clothes drying chamber 10, and the clothes drying effect on the inner wall of the inner barrel 12 can be realized by matching the rotation of the inner barrel 12. Therefore, when there are few clothes in the clothes drying chamber 10, the clothes are attached to the inner wall of the clothes drying chamber 10, so that the clothes drying can be performed by adopting the mode, which is beneficial to improving the drying efficiency of a small amount of clothes, saving energy and improving the utilization efficiency of energy.

Referring to fig. 3 to 7, it can be understood that an air door may also be disposed between the air outlet 211 of the fan 21 and the outer air zone 23, and the air door may be used to open and close the outer air zone 23 to control the on-off between the air outlet 211 of the fan 21 and the outer air zone 23, that is, to separately control whether the hot air generated by the fan 21 enters the outer air zone 23.

Still referring to fig. 3 to 7, it should be noted that the opening and closing of the damper 25 can be controlled manually, or the opening and closing of the damper 25 can be controlled by detecting the weight of the clothes in the clothes drying chamber 10. Specifically, when it is detected that the weight of the laundry is light, the damper 25 may be closed so that the hot wind is blown only to the outside wind zone 23. When the heavy weight of the laundry is detected, the damper 25 may be opened to blow the hot wind to the outer wind zone 23 and the inner wind zone 22 at the same time.
