Referring to fig. 2 to 5, fig. 5 is a schematic diagram of an embodiment of the air duct structure in the cylinder according to the present invention. The washing and drying integrated machine is provided with an outer barrel 3 and an inner barrel 2 which are sequentially arranged from outside to inside, a washing and drying space 200 is arranged in the inner barrel 2, an air duct structure 1 in the barrel is fixedly connected with the inner barrel 2, the air duct structure 1 in the barrel is positioned in the center of the washing and drying space 200, and the extending direction of the air duct structure 1 in the barrel is parallel to the axial direction of the inner barrel 2. The rear middle part of the outer cylinder 3 is provided with a hot air inlet 31, and the hot air inlet 31 faces the air inlet 112 of the air duct structure 1 in the cylinder. The rear upper portion of the outer cylinder 3 has a return air inlet 32. Because the inner barrel 2 is a porous structure, the washing and drying space 200, the air channel inside the air channel structure 1 in the barrel, the hot air inlet 31 and the air return opening 32 are communicated with each other.
Because the washing and drying all-in-one machine mainly washes and dries the processing to the clothing to daily, if a section of thick bamboo inner air duct structure 1 is the overall structure of non-telescopic, be located the central authorities of washing and drying space 200 and a section of thick bamboo inner air duct structure 1 extends to the front portion from the rear portion of washing and drying space 200, an air duct structure 1 then must cause the hindrance to the activity of clothing and rivers in a section of thick bamboo, and the hedging effect between clothing and the rivers weakens, and the washing effect then descends.
In addition, in order to ensure the circulation of hot air, the air duct structure 1 in the drum is provided with a completely hollow air duct 100, only one end of the air duct structure 1 in the drum is fixedly connected with the inner drum 2, and the clothes after water absorption have larger mass, if the air duct structure 1 in the drum is of a non-telescopic integral structure and extends from the rear part to the front part of the washing space 200, when the inner drum 2 rotates to work, the water-absorbing clothes collide with the air duct structure 1 in the drum, so that not only the air duct structure 1 in the drum can be damaged, but also the clothes can be damaged.

The in-tub air duct structure 1 extends from the rear to the front of the washing and drying space 200 at this time.
After that, the heat pump system is activated, the hot wind enters the wind tunnel 100 through the hot wind inlet 31 and the wind inlet 112 in sequence, and then the hot wind is discharged from and through the plurality of air supply through holes 111, 112, and 113. Because the clothing is located the periphery of a section of thick bamboo interior air duct structure 1, encircle a plurality of air supply through-holes that set up and realize 360 degrees air supplies in order to carry out even stoving to the clothing everywhere in the section of thick bamboo, the air current is sent out from return air inlet 32 at last.

In other embodiments, the elastic member is a pressure spring between two adjacent air duct sections, and the parts with opposite polarities face each other between the electromagnet device and the electromagnet after being electrified. The two air duct sections are kept in a contraction state through magnetic attraction, the electromagnet device controls current to enable the magnetic field to be changed into zero, and the pressure spring releases elastic potential energy to enable the two air duct sections to tend to change in an extension state.
In other embodiments, the last air duct section in the extending direction of the air duct structure in the drum does not have a blocking wall for blocking the air duct, and when the air duct structure in the drum is in the extended state, the end of the last air duct section is in contact fit with the cover body of the washing machine, and the cover body of the washing machine blocks the end of the air duct.
In other embodiments, the plurality of air duct sections are sequentially sleeved from inside to outside along the extending direction of the air duct structure in the barrel.
