Embodiment 1

[0033] like Figure 4 to Figure 7 As shown, the drum shaft 3 at the rear end of the dryer drum according to the present invention corresponds to the housing rear plate 4, and between the drum shaft 3 and the housing rear plate 4 is a conductive rolling ball 8 and a connecting piece 11, the connecting piece 11 is fixed on the rear plate 4 of the shell, and the position corresponding to the rolling ball 8 is provided with an elastic sheet 12. The elastic sheet 12 is close to the rolling ball 8, and its elastic force makes the rolling ball 8 close to the end surface of the roller shaft 3. The connecting piece 11 is fixed on the outside of the back plate 4 of the housing by fixing screws 13, the rear plate 4 is a hollow hole 14 corresponding to the rolling ball, the hollow hole 14 of the back plate is slightly larger than the diameter of the rolling ball 8, and the elastic piece 12 is " U"-shaped stamping structure, which blocks the rolling ball 8 in the hollow hole of the back pl...

Embodiment 2

[0035] like Figure 8 As shown, the drum shaft 3 at the rear end of the dryer drum according to the present invention corresponds to the housing rear plate 4, and between the drum shaft 3 and the housing rear plate 4 is a conductive rolling ball 8 and a spring 15, and one end of the spring 15 is It is close to the rolling ball 8, and the other end is close to the shell rear plate 4. The rolling ball 8 and the spring 15 are independent individuals. In order to fix the spring 15 and the rolling ball 8 without displacement, the rolling ball 8 and the spring 15 can also be It is fixed as a whole, and the other end of the spring 15 is fixed with the rear plate 4 .

Embodiment 3

[0037] like Figure 9 As shown, the drum shaft 3 at the rear end of the dryer drum according to the present invention corresponds to the housing rear plate 4, and between the drum shaft 3 and the housing rear plate 4 is a conductive rolling ball 8 and an elastic sheet 16, the elastic sheet 16 is integrated with the shell back plate 4, correspondingly close to the rolling ball 8, and its elastic force makes the rolling ball 8 close to the end surface of the cylinder shaft 3.

[0038] The end surface of the roller shaft in the present invention is a plane, so that the contact between the rolling ball and the roller shaft is at one point, thereby reducing the rotating friction of the roller and reducing the noise.

[0039] In the present invention, a rolling ball and an elastic member are installed between the shell rear plate and the roller shaft, and the elastic member presses the rolling ball tightly on the rear end surface of the installed roller rotating shaft, so as to real...

Abstract

The invention discloses a ground structure for a rolling drum of a clothes dryer. The clothes dryer comprises a shell and the rolling drum arranged in the shell, wherein a rolling drum shaft at the rear end of the rolling drum is supported on a supporting base inside a back plate of the shell; and a conductible elastic connecting part is arranged between the rolling drum shaft and the back plate of the shell, is closely connected with the rolling drum shaft and the shell respectively, and comprises a rolling ball and an elastic part, wherein the rolling ball is arranged in a shaft hole of the supporting base of the rolling drum shaft, one side of the rolling ball is closely attached to one end surface of the rolling drum shaft, and the other side of the rolling ball is closely attached to the elastic part. The elastic part is a connecting sheet, the connecting sheet is fastened on the back plate of a box body by two screws, the middle part of the connecting sheet is provided with an elastic sheet, the position on the elastic sheet corresponding to the back plate is provided with a round hole which is used for placing the rolling ball. The ground structure has the advantages of simple and compact structure, convenient installation, and better mechanical and electrical connection stability, achieves the aim of reliable ground of the rolling drum, and does not produce the abrasion to the rolling drum.

Description

technical field [0001] The invention relates to a clothes dryer, in particular to a drum grounding structure capable of eliminating static electricity or electric leakage on the drum. Background technique [0002] Generally, a clothes dryer is a household appliance widely used for drying clothes. Recently, clothes dryers with additional functions have been under development. A traditional clothes dryer includes a cabinet, a drying drum, a heater, a blower, and a motor. During the clothes drying process, the drum rotates in a clockwise / counterclockwise direction, and air heated by a heater is supplied to the drum through a blower to dry laundry in the drum. [0003] However, during the drying process, static electricity may be generated on the dried laundry due to friction between the laundry and the drum (or between the motor belt and the drum). Therefore, a user may feel discomfort or an unpleasant feeling when putting on a piece of dry laundry, so static electricity nee...
