[0043] like Figures 1 to 6 As shown, a clothes dryer according to the present invention comprises a drying air duct, a first drum 1 and a second drum 2 .

[0044] The first drum 1 is rotatably arranged and communicated with the drying air duct. The first drum 1 can contain clothes.

[0045] The second drum 2 is rotatably disposed in the first drum 1. The second drum 2 can contain clothes.

[0046] An interlayer 3 is formed between the first drum 1 and the second drum 2 and is independently arranged from the second drum 2. The interlayer 3 and the second drum 2 are respectively communicated with the drying air duct.

[0047] In the present invention, by arranging the rotatable first drum 1 and the second drum 2, two independent drying chambers of the interlayer 3 and the second drum 2 are formed, and different types of clothes can be dried in different areas, which can improve the drying effect, help to keep the clothes clean and tidy, help to reduce health risks, and facilitate user use.

[0048] Specifically, the clothes dryer further comprises a box body and a door body, a first clothing loading port is usually arranged at the front side of the box body, and the door body is rotatably arranged at the front side of the box body to close or open the first clothing loading port.

[0049] The first drum 1 can be supported and arranged in the box, and the drum openings of the first drum 1 and the second drum 2 are arranged opposite to the first clothing loading opening. The second drum 2 can be installed in the first drum 1 through the first clothing loading opening.

[0050] The drying air duct is arranged in the box body. A circulating fan, a dehumidifying device and a heating device are arranged in the drying air duct.

[0051] The single-drum clothes dryer in the prior art has only one first drum 1 disposed therein, and the first drum 1 is rotatably disposed in the housing, the air inlet end of the drying air duct is connected to the drum mouth of the first drum 1, and the air outlet end of the drying air duct is connected to the air inlet end of the first drum 1.

[0052] When drying clothes, first put the wet clothes into the first drum 1, turn on the circulation fan, the dehumidification device and the heating device; the low-temperature and humid air in the first drum 1 enters the air inlet end of the drying air duct under the drive of the circulation fan, the dehumidification device dehumidifies the low-temperature and humid air to convert it into low-temperature dry air, and the heating device can heat the airflow to convert the low-temperature dry air into high-temperature dry air; the high-temperature dry air enters the first drum 1 from the air outlet end of the drying air duct to dry the wet clothes, and the high-temperature dry air dries the clothes and then converts into low-temperature and humid air and enters the drying air duct, and the clothes are dried in a continuous cycle.

[0053] Underwear and other intimate apparel as well as baby clothes have high requirements for hygiene. Drying them together with outerwear or sharing the same drum for a long time may cause hygiene problems.

[0054] The clothes dryer described in the present invention has the second drum 2 additionally arranged inside the first drum 1, and the interlayer 3 is formed between the first drum 1 and the second drum 2.

The interlayer 3 and the second drum 2 are two independent drying chambers that are not connected to each other, and different types of clothes can be dried in different areas, which is conducive to the cleanliness of clothes, can reduce hygiene risks, and is convenient for users to use.

[0055] The first drum 1 and the second drum 2 are coaxially arranged, and both the first drum 1 and the second drum 2 can rotate, so as to evacuate the clothes in the interlayer 3 and the second drum 2, increase the drying area of ​​the clothes, and improve the drying effect.

[0056] The clothes dryer of the present invention has multiple working modes. Clothes of different types are placed in both the interlayer 3 and the second drum 2, and different types of clothes can be dried in different areas at the same time. The interlayer 3 and the second drum 2 are two independent drying chambers. Clothes can be placed in the interlayer 3 or the second drum 2 and can be used separately.

[0057] like Figure 3 As shown, the second roller 2 is detachably disposed in the first roller 1 .

[0058] In the above scheme, the second drum 2 can be detachably arranged in the first drum 1, so as to realize zoned drying of different types of clothes. The second drum 2 can also be removed according to actual needs, and the first drum 1 can be used alone to dry the same type of clothes in large quantities.

[0059] Specifically, a driving motor is provided in the box body, and the driving motor is connected to the first roller 1 through a belt, and can drive the first roller 1 to rotate. A supporting shaft is connected to the rear end of the first roller 1, and the supporting shaft can rotate; a rotatable supporting wheel is provided in the box body, and the supporting wheel is arranged close to the door body, and the supporting wheel is arranged below the first roller 1 and contacts the outer peripheral wall of the first roller 1, and the supporting wheel can play the role of supporting the first roller 1 and reducing friction resistance.

[0060] The second drum 2 is detachably arranged in the first drum 1. When the second drum 2 is installed in the first drum 1, the second drum 2 is fixed in the first drum 1. The interlayer 3 and the second drum 2 are two independent drying chambers. The first drum 1 and the second drum 2 rotate synchronously, and different types of clothes can be dried in different areas. When the user needs to dry a large number of clothes of the same type, the second drum 2 can be removed and the clothes can be placed in the first drum 1 for drying, and the second drum 2 can be used as a clothes basket.

[0061] Preferably, underwear and other close-fitting garments and baby clothes are small in size or volume, and the second drum 2 can be specially used for drying underwear and other close-fitting garments and baby clothes, which is helpful to keep the clothes clean and tidy.

[0073] Specifically, the first stirring blade 12 rotates with the first drum 1 to stir the clothes placed in the first drum 1, thereby increasing the drying area of ​​the clothes and improving the drying effect. The cross section of the first stirring blade 12 is triangular, and one end of the first stirring blade 12 away from the first drum 1 is configured as an arc-shaped surface transition, which can reduce damage to the clothes when the first stirring blade 12 rotates.

[0074] The length of the first stirring blade 12 in the radial direction of the first drum 1 is shorter than the length of the supporting block 111 , so as to facilitate the installation of the second drum 2 .

[0075] Preferably, two first stirring blades 12 are provided and are symmetrically arranged in the first drum 1, which is beneficial to improving the drying effect of clothes.

[0076] The front flange 13 is installed at the barrel end of the first drum 1, and there is a gap between the front flange 13 and the first stirring blade 12, and the support block 111 is clamped between the first stirring blade 12 and the front flange 13. Before installing the second drum 2, the support block 111 needs to be pre-installed.

[0077] The front flange 13 has a second clothing inlet, the second drum 2 is provided with a flange at its mouth, the flange has a third clothing inlet, and the first clothing inlet, the second clothing inlet and the third clothing inlet are arranged one by one so that clothing can be taken and placed normally.

[0078] The first clothing loading port, the second clothing loading port and the third clothing loading port can be set as circular ports. The diameter of the second drum 2 is smaller than the diameter of the second clothing loading port and also smaller than the diameter of the first loading port, so as to facilitate the installation and removal of the second drum 2.
