BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is a schematic diagram of a drum type washer dryer;
FIG. 2 is a partial view of a gasket;
FIG. 3 is a view of the gasket in FIG. 2 with an annular peripheral wall being partially removed; and
FIG. 4 is a sectional view of the gasket in FIG. 2 in an A-A direction.
DETAILED DESCRIPTION
As shown in FIG. 1, a drum type washer dryer 100 includes a housing 2. A door opening 20 is provided on the housing 2. A door 4 connected to the housing 2 can open or close the door opening 20. The door 4 includes a protruding portion 40 protruding toward the inside of the housing 2, which is usually made of glass. A tub 6 is arranged in the housing 2. A rotatable drum 8 is arranged in the tub 6. Clothes are cleaned and/or dried in the drum 8. The tub 6 includes a tub opening 60 opposite to the door opening 20. A gasket 10 is connected in a sealed manner to the door opening 20 and the tub opening 60 respectively, so that washing liquid or hot air in the tub 6 does not overflow through the door opening 20 or the tub opening 60. The protruding portion 40 can push the clothes to the drum 8, to prevent the clothes from staying in the gasket 10 and not being fully washed or dried. Because the tub 6 vibrates relative to the housing 2 during operation of the drum type washer dryer 100, the gasket 10 is usually made of an elastic material such as rubber, and the gasket 10 usually includes an annular peripheral wall 12 having axial wrinkles. The tub 6 has a greater movement freedom degree relative to the housing 2 due to the wrinkle part.
An air passage 14 is provided on the annular peripheral wall 12. Preferably, the air passage 14 is provided on a horizontal plane on which a central axis 11 of the annular peripheral wall 12 is located. In addition, preferably, the air passage 14 is integrally formed on the annular peripheral wall 12.
A first end 91 of a drying air channel 9 is connected to a rear wall 62 of the tub 6 to be in fluid communication with the tub 6, and a second end 92 of the drying air channel is connected to the air passage 14 of the gasket 10. A blowing device 94 and a heating device 96 are arranged in the drying air channel 9. The blowing device 94 can blow air to circulate and flow in the tub 6, the drum 8, and the drying air channel 9. A flow direction is that the air flows from the first end 91 of the drying air channel 9 to the second end 92, and enters the tub 6 and the drum 8 from the air passage 14. The heating device 96 can heat the air passing through the drying air channel 9, so that the air entering from the air passage 14 has a suitable temperature. Alternatively, in some clothes processing procedures, the air may flow while the heating device 96 is not started.
As shown in FIG. 1 and FIG. 4, an outlet 15 of the air passage 14 includes an extension wall 16 extending toward a radial inner side of the annular peripheral wall 12. The extension wall 16 bends to a direction of a rear portion of the drum 8, so that the outlet 15 of the air passage 14 faces toward the rear portion of the drum 8, and the air is guided to the rear portion that is not easy to reach of the drum 8 so as to come into contact with the clothes more fully.
The extension wall 16 includes an edge 18. The edge 18 also forms an edge of the outlet 15. Preferred embodiments include that a part of the extension wall 16 that is close to the edge 18 is approximately parallel to the central axis 11 of the annular peripheral wall 12. In this way, more airflows are guided by the extension wall 16 to above the rear portion of the drum 8, and then flow to the first end 91 of the drying air channel 9 provided at a lower position of the rear wall 62 of the tub 6. Therefore, the airflow distribution is more uniform. In the related art, an airflow cannot easily reach above the rear portion of the drum 8. As shown in FIG. 2 and FIG. 3, preferably, the edge 18 is a flat structure in a plane perpendicular to the central axis 11 of the annular peripheral wall. In this way, the airflow distribution in a left-right direction shown in FIG. 2 and FIG. 3 is uniform. On the contrary, if a middle portion of the edge 18 protrudes upward, most airflows flow out from two sides, and the clothes in a middle portion of the drum 8 cannot come into contact with the airflows fully. If the middle portion of the edge 18 is recessed downward, most airflows flow to the middle portion of the drum 8, and the clothes close to two sides cannot come into contact with the airflows fully.
As shown in FIG. 3, preferably, the air passage 14 includes a contraction portion 19 causing a flow section to decrease in an airflow direction. The contraction portion 19 forms a smooth step surface inward. Therefore, the airflows flowing through the step surface can be accelerated, and the penetration of the airflows on the clothes is enhanced. In addition, a gap between the air passage 14 and the wrinkles of the annular peripheral wall 12 can be increased, to prevent or reduce a possibility of friction between the air passage and the wrinkles of the annular peripheral wall during vibration.
To prevent the clothes from being stuck between the protruding portion 40 of the door 4 and the gasket 10, as shown in FIG. 2, the radial inner side of the annular peripheral wall 12 includes a clothes deflection device 30 radially protruding inward. Preferably, the clothes deflection device 30 and the annular peripheral wall 12 are integrally formed. In the embodiment shown in FIG. 2, the clothes deflection device 30 includes two clothes deflection elements 32 respectively located on two sides of the outlet of the air passage 14. In another embodiment, the clothes deflection device 30 may include one or more clothes deflection elements 32.
The outlet 15 of the air passage 14 is fixedly connected to the clothes deflection device 30. For example, one side of each of the two clothes deflection elements 32 is connected to a side wall 17 of the outlet 15, and another side of each of the two clothes deflection elements 32 leans to the annular peripheral wall 12 and is in smooth transition.
Preferably, peak portions 34 of the two clothes deflection elements 32 are respectively connected to the edge 18 of the extension wall 16. Therefore, in a process that pushing the clothes, the edge 18 of the air passage 14 and the clothes deflection elements 32 have a better integrity and also have good advantages and improvements in terms of strength, so that the clothes can be better pushed, and a better deformation resistance capability is provided.
Preferably, the edge 18 and another side of each of the two clothes deflection elements 32 that is away from the air passage 14 are in smooth transition. Therefore, friction and pulling to the clothes can be reduced.
The various specific implementations described above and shown in the accompanying drawings are only used to illustrate the invention, but are not all of invention. Any variation made by a person of ordinary skill in the art to the invention within the scope of the basic technical concept of the invention shall fall within the protection scope of the invention.
