Abstract

The utility model discloses a sealing device between an inner and an outer tubs of a washing machine. The utility model is composed of a rotary retainer ring fixed on a flange disk of the inner tub and a sealing box fixed on the tub bottom of the outer tub, and the utility model is matched and embedded with a skeleton seal ring and sealing filler; gap between the inner and the outer tub bottoms can form a closed a water storage or a water discharging chamber. No use water amount can be reduced, and the purposes of reasonably using water and saving water can be achieved. The utility model has the advantages of simple structure, easy fabrication, and good tightness; the utility model is an energy saving component of the washing machine.

Description

Seal arrangement between the inside and outside bucket of washing machine

The utility model relates to the improvement of part of washing machine, the seal arrangement between especially a kind of inside and outside bucket of washing machine, and it belongs to household electrical appliance technical field.

In the space between the inside and outside bucket of existing washing machine, a certain amount of water of storage in washing process, its water level is the same horizontal line of inside and outside bucket, yet the water in this space is little to the laundry effect effect, this part water is unnecessary, thereby cause washing machine wash water amount big, can not reasonable use of water, using water wisely.

The purpose of this utility model is to improve the structure of part of washing machine, it is exuberant to the outer seal arrangement of interior bucket bucket wall to design a kind of scouring water that prevent, scouring water are only retained in inside and outside bucket bucket end cavity, reduces no water consumption, reach reasonable use of water, water-saving purpose.

Task of the present utility model has following technological scheme to realize, developed a kind of washing machine in, seal arrangement between outer bucket, in the cavity of inside and outside bucket bucket at the end, be recessed square position shape by the rotation back-up ring on the bucket bucket end flange plate in being bolted to, it is provided with the corresponding weep hole that mates with this flange plate and installs and fixes the hole with the friction tight contact of flange plate square position, sliding fit is fixed with the closedtop mouth of sealing case on the flange plate card of rotation back-up ring outer, this seals and rotates and is provided with oral pillar stuffing box packing chamber circle between the gabarit post block face of back-up ring, be embedded with backbone sealing ring in this chamber circle, the bucket bucket is fixed with the base of sealing case by bolt seal at the end outside, thereby is formed in the box cavate seal arrangement of inside and outside bucket bucket at the end.

Seal arrangement between the inside and outside bucket of this washing machine, described sealing case, it is an asymmetric conical shell, the closedtop mouth actinal surface of its vertex of a cone and flange plate sliding fit is a wear-resistant material, with reach and the flange plate card between tight sliding fit, and constitute oral pillar stuffing box packing chamber circle and the rotation back-up ring is carried out encapsulation process with the rotation back-up ring, also being provided with stuffing box packing chamber circle on the base of this box and outer bucket bucket end sealing and fixing, this chamber circle is located on the inboard circle of fixed bolt hole.

Seal arrangement between the inside and outside bucket of this washing machine, the stuffing box packing of described sealing and fixing on the sealing case base, it be the seal ring of elastic material, and it is inlaid in the circle of stuffing box packing chamber, and its shape can be pair " H " shapes, also can be " O " shape.

Seal arrangement between the inside and outside bucket of this washing machine, described backbone sealing ring, it is the seal ring of elastic material, the inner ring face of this circle contacts with the gabarit block face of rotation back-up ring, this contact inner ring face is sucker-type three-jaw circle face, thereby constitutes the upper and lower tight seal circle to this post block face.

Its advantage of seal arrangement of the present utility model is: owing to designed platform cone seal box, it is arranged on inside and outside bucket bucket at the end, and there is the dual fail-safe seal ring setting-in of balladeur train seal ring and base sealing to seal, reached and sealed tight requirement, realized that the restriction scouring water only retain in gap at the bottom of the bucket, reduce no water consumption, reached water-saving purpose.This apparatus structure is simple, makes and installs easily, has higher sealability.

The utility model embodiment further describes as follows in conjunction with the accompanying drawings, as shown in the figure:

Fig. 1 is: the sealing device structure generalized section between the inside and outside bucket of washing machine.

Fig. 2 is: the square position structural representation of rotation back-up ring.(the A-A view of Fig. 1).

Make this seal arrangement, be in by bolt 9 flange plate 2 and rotation back-up ring 3 being fixed at the bottom of 1 barrel in the bucket on, reducer shaft 10 passes rotation back-up ring 3, the central driving hole at the bottom of 1 barrel in flange plate 2 and the interior bucket and constitute the interior bucket 1 of rotation.On the square position of the rotation back-up ring 3 of recessed square position shape, be provided with the corresponding weep hole 11 of flange plate 2 couplings and install and fix hole 9 '.Be provided with the sealing case 6 of platform taper in the bucket end cavity between inside and outside bucket 1.5.The closedtop mouth sliding fit of this box 6 is on the card of flange plate 2, on the base of this box is fixed at the bottom of 5 barrels in the outer bucket by bolt 8.Be embedded with backbone sealing ring 4 between the gabarit post block face of the closedtop mouth of this box 6 and rotation back-up ring 3, this circle 4 is the elastic material of rubber material, and its shape is the inner ring face seal circle of sucker-type three-jaw circle face.Because three-jaw 13 circle faces are adsorbed on the sealing effect of the tight seal up and down that forms rotation back-up ring 3 on the gabarit post block face that rotates back-up ring 3 tightly.On the base of sealing case 6,, compress the stuffing box packing 7 that is inlaid in two " H " shapes in the circle of stuffing box packing chamber by bolt 8.Scouring water can only retain in sealing case 6 like this, or 12 discharges of the drain opening on outer bucket 5, and are unlikely the exuberant waste that causes water outside 1 barrel of wall of interior bucket of water.

Claims

1, in a kind of washing machine, seal arrangement between outer bucket, it is characterized in that: in the cavity of inside and outside bucket bucket at the end, be recessed square position shape by the rotation back-up ring on the bucket bucket end flange plate in being bolted to, it is provided with the corresponding weep hole that mates with this flange plate and installs and fixes the hole with the friction tight contact of flange plate square position, sliding fit is fixed with the closedtop mouth of sealing case on the flange plate card of rotation back-up ring outer, this seals and rotates and is provided with oral pillar stuffing box packing chamber circle between the gabarit post block face of back-up ring, be embedded with backbone sealing ring in this chamber circle, the bucket bucket is fixed with the base of sealing case by bolt seal at the end outside, thereby is formed in the box cavate seal arrangement of inside and outside bucket bucket at the end.
