Abstract

Disclosed is a sealed structure of a barrel body unit and a barrel bottom unit of the full-automatic washing machine, the primary technical scheme of the utility model comprises a barrel body unit and a barrel bottom unit, the utility model is characterized in that a barrel bottom groove with upward openings is equipped along the circumference on upper edge of bottom of a plastic barrel, a sealing ring is placed in the barrel bottom groove, the sealing ring comprises left and right wings, and forms a structure of 'V' shape with the bottom, a outwardly outspread step is equipped on lower portion of the barrel body, upper edges of the left and right wings are respectively contacted with the steps.

Description

The hermetically-sealed construction of dehydrating vessel in washing machine

The utility model belongs to a kind of annex of washing machine, refers in particular to a kind of staving parts of automatic washing machine and the hermetically-sealed construction of bucket bottom parts.

On the interior bucket of general double-cylinder type automatic washing machine the dewatering hole that communicates with outer bucket is arranged, during laundry, between inside and outside bucket, water is arranged, during dehydration, the rotation at a high speed of interior bucket, because of action of centrifugal force, the dewatering hole in utilizing on the bucket is thrown the water in the clothing out.Because during washing, the water between inside and outside bucket does not have much effects, thereby many manufacturers all managing to seek a kind of water-saving type washing machine, to save this part water, cut the waste.

For this reason, must manage to cancel the dewatering hole on the inner barrel wall, the wall of interior bucket is designed to outward-dipping structure, so that the water in during laundry in the bucket can not flow to outer bucket, when dehydration, the water on the clothing is climb along inner barrel wall under action of centrifugal force, be thrown between inside and outside bucket from the upper edge of interior bucket, flow out from outer barrel bottom again.The bucket end of bucket, had certain intensity and certain sealing property in this just required.

The purpose of this utility model is the hermetically-sealed construction of a kind of dehydrating vessel in washing machine of design, to satisfy the requirement of producing the water-saving type washing machine, improves the sealing of the bucket end and staving.

Its main technical schemes comprises staving parts and bucket bottom parts, it is characterized in that the upper limb edge at the bottom of Plastic Drum circumferentially is provided with the bucket end groove that opening makes progress, in groove at the bottom of the bucket, place sealing ring, the sealing circle constitutes one " v " font structure by the left and right wing and bottom, in the bottom of staving one outward extending step is arranged, the upper limb of the left and right wing contacts with step respectively;

The height that constitutes the outer wing of bucket end groove is lower than the height of its inner wing, correspondingly, in the left wing of sealing ring one part of extending is arranged left, and this part covers on the upper end of outer wing.

Inwall edge at staving circumferentially is provided with the dehydration orifice plate equably, so that dehydration, edge is provided with the balance ring parts thereon, to guarantee the stationarity of dehydration barrel when rotating at a high speed, junction at staving parts and bucket bottom parts is provided with sealing ring, leak avoiding, at the inwall of balance ring parts the liquid detergent tipping bucket is set, so that washing agent can be added to the position of requirement.

The utility model has the advantages that owing at the bottom of Plastic Drum, be provided with sealing ring with the contact site of staving, avoided the seepage of water, the sealing circle is made up of two wings, interplane gapped at two, one outward extending step is arranged on staving, during installation, the upper end of left and right closely contacts with step, make it produce certain deformation and pretightning force, improved sealing effectiveness, the left wing of sealing ring stretch out cover on the outer wing of short bucket end groove after, close mutually when step and the outer wing of staving, can produce better sealing effectiveness when pushing left wing's upper limb.

Fig. 1 is the dehydration barrel structure chart.

Fig. 2 is a sealed structure chart.

As shown in the figure:

6 upper limb is along the bucket end groove 11 that opening makes progress circumferentially is set at the bottom of Plastic Drum, in groove at the bottom of the bucket 11, place sealing ring 7, sealing circle 7 is by a left side, right flank 15,13 constitute one " v " font structures with bottom 17, one outward extending step 14 is arranged in the bottom of staving 9, a left side, right flank 15,13 upper limb contacts with step 14 respectively, the height that constitutes the outer wing 16 of bucket end groove 11 is lower than the height of its inner wing 12, correspondingly, left wing at sealing ring 7 has a part of extending left, this part covers on the upper end of outer wing 16, inwall edge at staving 9 circumferentially is provided with dehydration orifice plate 8 equably, edge is provided with balance ring parts 10 thereon, junction at staving parts 9 and bucket bottom parts 6 is provided with sealing ring 7, at the inwall of balance ring parts 10 liquid detergent tipping bucket 2 is set.
