Detailed description of the invention

Describe embodiment of the present utility model below in detail, the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar element or has the element of identical or similar functions from start to finish.Be exemplary below by the embodiment being described with reference to the drawings, be intended to for explaining the utility model, and can not be interpreted as restriction of the present utility model.

Describe in detail according to the dryer of the utility model embodiment below with reference to accompanying drawing.

As shown in Figures 1 to 4, according to the dryer of the utility model embodiment, comprising: casing 10, air bells cap 20, bearing 30, inner core 40 and grounding assembly 50.It is pointed out that in the utility model, described dryer refers to the machine with clothes drying function, for example usually said " dryer " or " washing-drying integral machine ".

Particularly, air bells cap 20 is located on rear (as shown in Figure 1 arrow after indicated direction) end face of casing 10 and has bearing installation portion 201 on air bells cap 20.

Bearing 30 is arranged on bearing installation portion 201 below air bells cap 20.

Inner core 40 is located in casing 10.On the bonnet of inner core 40, there is the rotating shaft 401 extending back.Rotating shaft 401 is passed backward air bells cap 20 and is coordinated with bearing 30.The rear end of rotating shaft 401 protrudes from the rear surface of bearing 30 backward.

Grounding assembly 50 is located on the rear surface of bearing 30 and is connected with rotating shaft 401.

That is, if interior bucket 40 produces static, static can pass to grounding assembly 50 via rotating shaft 401, and grounding assembly 50 passes to air bells cap 20 by bearing 30 by static, and static is passed to casing 10 by air bells cap 20, and static is finally discharged by the earth connection of casing 10.

As shown in Figure 3 and Figure 4, according to an example of the present utility model, grounding assembly 50 comprises ground connection lid support on the rear surface that is located at bearing 30 501 and is located at the ground connection lid 502 on the rear surface of ground connection lid support 501.The rear end face of rotating shaft 401 is against ground connection lid 502.Thus, connect reliably.

Advantageously, grounding assembly 50 also comprises ground connection ball 503.Ground connection ball 503 is located between ground connection lid support 501 and ground connection lid 502.Ground connection ball 503 is respectively against the rear end face of ground connection lid 502 and rotating shaft 401.Thus, can make the sliding friction between rotating shaft 401 and ground connection lid 502 become rolling friction, to increase the service life.

Further, on ground connection lid support 501, there is the through hole 5011 that holds ground connection ball 503, on ground connection lid 502, have relative with through hole 5011 and to the protuberance 5021 of rearward projection.The rear end of rotating shaft 401 is plugged in through hole 5011 backward by front (as shown in Figure 1 arrow before indicated direction).Thus, connection is more reliable.

Brief description is once according to the installation process of the dryer of the utility model embodiment.

Casing 10 is provided, air bells cap 20 is arranged on the rear end face of casing by screw or rivet.Bearing 30 is arranged on the bearing installation portion 201 of air bells cap 20.Ground connection lid support 501 is arranged on bearing 30.Interior bucket 40 is arranged in casing, makes rotating shaft 401 coordinate with bearing 30 and the rear end of rotating shaft 401 is plugged in the through hole 5011 of ground connection lid support 501 through air bells cap 20.Ground connection ball 503 is arranged in through hole 5011.Finally ground connection lid 502 is connected with ground connection lid support 501 so that ground connection ball 503 covers 502 and the rear end of rotating shaft 401 against ground connection respectively.

According to the dryer of the utility model embodiment, realize the effective interconnection of inner core and casing, casing, by power line ground connection, is realized the effective grounding of inner core, effectively derives inner core static.
