CN2429548Y - Oscillation-proof rotating device for dewatering barrel - Google Patents

Abstract

The utility model relates to an oscillation-proof rotary device for a dewatering barrel. The utility model mainly solves the barrel beating phenomenon when the dewatering barrel rotates, and the barrel beating phenomenon is caused by the eccentricity of the dewatering barrel when clothes are filled. The device has the technical proposal that the upper part of a dewatering outer barrel is fixed with a bottom seat; an outer ring is fixed on the bottom seat; rolling bodies can roll in grooves of the outer ring and an inner ring; a holding rack keeps the rolling bodies uniformly distributed; the upper part of the dewatering barrel is fixed with a circle of rubber plates. When the dewatering barrel eccentrically rotates, the dewatering barrel rapidly achieves standard rotation speed depending on the inner ring, and the barrel beating phenomenon is prevented. The utility model is used for a dewatering system of the washing machine.

Description

Dehydration barrel resistant and oscillation resistant tumbler

The utility model relates to a kind of dehydrating vessel in washing machine resistant and oscillation resistant tumbler, when using the dehydration of washing machine washing clothes, by it is that big part or dehydrate are when too many, fill in the dehydration barrel unavoidably monolateral (promptly washings is many, and another side is few) on one side with hand, produce unusual vibration and constantly beat barrel and cause and beat casing in the dehydration barrel entry into service, and constantly send the violent abnormal voice of ", ", it not only influences the normal use of washing machine, and influences the service life of washing machine.

In order to address this problem, common way is when the bucket phenomenon occurring beating, allow it stop operating after, clothing is readjusted, test running still occurs beating barrel, adjustment again.China Patent No. ZL97229486.4 proposes on dehydration barrel and outer barrel of top relative position of dehydration, if the permanent magnet of same polarity, repulsion by magnetic patch, make dehydration barrel remain on forever body in work in the heart, but the magnetic patch of making greater than dehydration barrel the centrifugal force when monolateral is difficult, because the distance between the outer bucket of dehydration barrel and dehydration is big inadequately.

The purpose of this utility model is that a kind of dehydrating vessel in washing machine resistant and oscillation resistant tumbler will be provided, and it can prevent effectively that dehydration barrel from beaing casing, and reaches rated engine speed rapidly.

The purpose of this utility model is achieved in that the base of a garden annular (section is the L type) is screwed the top of bucket outside fixing dehydration, the outer ring of garden annular is fastened on the base with screw, the inner surface of outer ring has a groove, it is (or cylindrical that (uniform) sphere is housed on the groove of outer ring, or cydariform) rolling element, the inside near rolling element is the inner ring of annular, the appearance of inner ring also has a groove relative with the groove of outer ring, when inner ring rotates, rolling element can roll in the groove between outer ring and the inner ring, uniform rolling element respectively is equipped with the corrugated retainer of a circle (or annular retainer up and down, the uniform hole of putting rolling element is arranged) in the frame, make rolling element be uniformly distributed in circumference, retainer is not having the groove of rolling element up and down, the available rivet that carries connects or makes an integral body, one circle rubber slab is screwed on the top of revolvable dehydration barrel outer surface, leaves spacing between the inner surface of rubber slab and inner ring.Also can be without rubber slab, and inner peripheral surface is screwed on dehydration barrel outer surface top.

This installs except that screw and rubber slab, all available injection molding of other parts.Distance between rubber slab surface and the inner ring inner surface can be controlled in 4 millimeters-10 millimeters; When the monolateral rotation of dehydration barrel, earlier against the inner ring rotation, dehydration barrel reaches rated engine speed rapidly, deviate from part water after, dehydration barrel is left inner ring and is continued the dehydration rotation, has so just guaranteed that dehydration barrel no longer makes bucket.

The utility model is because only need to increase base, inner ring, outer ring, rolling element, retainer, rubber slab at original equipment, so simple in structure; Dehydration barrel is converted into the rolling friction rotation, the service life of having improved equipment because of monolateral causing beats casing; This device need not control appliance in addition, so easy to use.

The concrete structure of utility model is provided by following embodiment and accompanying drawing thereof.

Fig. 1 is the profile according to the dehydration barrel resistant and oscillation resistant tumbler that the utility model proposes.

Describe details and working condition in detail below in conjunction with Fig. 1 according to the concrete device that the utility model proposes.

This device comprises the base (8) of an annular (section is the L type), be screwed the top of bucket (1) outside dehydration, the outer ring of annular (3) is firm on base (8) with screw (2), the inner surface of outer ring (3) has the groove of a circular arc, close conveniently in order to adorn, outer ring (3) also can be made into two halves up and down, somatotype in the middle of arc groove, (uniform) spherical rolling element (5) is housed on the groove of outer ring (3), the inside near rolling element (5) is the inner ring (4) of annular, the outer surface of inner ring (4) also has the groove of a circular arc, when inner ring rotates, roll in the groove of rolling element (5) between outer ring (3) and inner ring (4), for can being evenly distributed on when inner ring (4) rotates between inner ring (4) and outer ring (3), rolling element (5) rolls, rolling element (5) all have up and down one the circle corrugated retainer (9), retainer (9) is at the groove that does not have rolling element (5) up and down, the available plastic rivet that carries connects, or make an integral body, rubber slab (7) is screwed the outer surface on dehydration barrel (6) top.

When the clothing in the dehydration barrel (6) is monolateral, dehydration barrel (6) begins rotation and just rotates against inner ring (4), because the frictional resistance of offset plate (7) can drive inner ring (4) and and then rotate, roll in the groove of rolling element (5) between outer ring (3) and inner ring (4) simultaneously, because the distance very little (having only 4 millimeters-10 millimeters) between offset plate (7) and the inner ring (4) will make dehydration barrel (6) reach rated engine speed rapidly, clothing moisture content begins to deviate from, bucket wall around clothing in the dehydration barrel is shifted under action of centrifugal force simultaneously, after deviating from part moisture content, moisture content reduces, off-centre also reduces, and dehydration barrel (6) is left inner ring (4) and continued the dehydration rotation.

Fig. 2 is the profile of dehydration barrel vibration tumbler of the rolling element of tape spool.

Describe details according to the concrete device that the utility model proposes in detail below in conjunction with Fig. 2.

This device comprises that the base (8) of an annular (section is L-type) is screwed and is taking off An annular is fixed with screw (2) in water outer barrel (1) top on base (8) Loam cake (10), loam cake (10) and base (8) have axis hole, and axle (11) is contained in loam cake (10) In the axis hole of base (8), cylindrical rolling element (5) is fixed on the axle, or axle (11) with roll Kinetoplast (5) is made an integral body, is pasted with one deck sheet rubber on the outer surface of rolling element (5) (12), be close in the groove of inner ring (4) outer surface of the annular of sheet rubber base (8) On the rolling element (5) of (uniform) 4-20 tape spool (11) is housed, a circle rubber slab (7) Be screwed on the outer surface top of dehydration barrel (6), rubber slab (7) and inner ring (4) it Between the distance 4 millimeters-10 millimeters, also can be without rubber slab (7), inner ring (4) is directly used spiral shell Nail is fixed on the outer surface top of dehydration barrel (6).

When the rotation of the dehydration barrel (6) of off-centre, have base (8), rolling element (5), loam cake (10), Inner ring (4) supports eccentric dehydration barrel and rotates, and all can reach rapidly rated engine speed, have prevented from beating The bucket phenomenon.
