Abstract

The utility model belongs to an attachment of washing machine, in particular to a barrel bottom injection-molding unit structure with a steel plate insert. The primary technical scheme of the utility model comprises a basin barrel bottom unit, the utility model is characterized in that a basin metal insert is equipped on a middle portion of the bottom of a basin plastic barrel, reinforced cutting holes are uniformly located along the circumference on outer edge of the bottom of the basin metal insert, water outlet holes and connecting holes are equipped on the middle portion of the bottom of the basin metal insert.

Description

The bucket bottom structure 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 bucket rising pouring plastic component structure with the steel plate inserts.

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 in this just required.

The purpose of this utility model is the bucket bottom structure 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 bucket intensity and the sealing at the end.

Its main technical schemes comprises the bucket bottom parts of basin shape, it is characterized in that the middle part at the bottom of basin moulds charging basket is provided with the metal insert of basin shape, and the outer rim at the bottom of the basin of this metal insert is cut the hole along circumferential uniform reinforcement, and the middle part at the bottom of basin is provided with osculum and connecting hole;

Edge at metal insert is provided with spline tooth, and the position corresponding to the edge of metal insert at the bottom of Plastic Drum is provided with the spline tooth that cooperates with spline tooth; Middle part at the bottom of basin is provided with locating hole; Described osculum and connecting hole have 4 respectively, on circumferentially being distributed at the bottom of the basin;

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

The utility model has the advantages that because metal insert is set at the bottom of bucket, improved the intensity at the bucket end, because metal insert is in being embedded at the bottom of the Plastic Drum, with injection mo(u)lding at the bottom of the Plastic Drum, compare with utilizing bolted mode simultaneously, its sealing is better; Secondly, metal insert is anchored at the bottom of utilizing spline tooth with Plastic Drum, and bonding strength is better, be provided with at the bottom of the basin strengthen cutting the hole after, during injection moulding, can in the hole, flow into a certain amount of plastics, help to improve at the bottom of the Plastic Drum and the adhesion of metal insert, and then improve its intensity; All help to compile current and improve intensity with the metal insert of basin shape at the bottom of the Plastic Drum of basin shape in addition, make water successfully the osculum through being positioned at the middle part flow out, can accurately and easily other parts be connected with other after being provided with connecting hole and locating hole at the bottom of the basin.

Fig. 1 is the dehydration barrel structure chart.

Fig. 2 is the metal insert structure chart.

As shown in the figure:

5 middle part is provided with the metal insert 4 of basin shape at the bottom of basin moulds charging basket, 15 outer rim is cut hole 16 along circumferential uniform reinforcement at the bottom of the basin of this

metal insert

4,15 middle part is along 4 osculums 10 and connecting hole 14 circumferentially are set respectively equably at the bottom of basin, at the edge of metal insert 4 spline tooth 12 is set, 5 positions corresponding to the edge 13 of metal insert 4 are provided with the spline tooth that cooperates with spline tooth 12 at the bottom of Plastic Drum, and 15 middle part is provided with locating hole 11 at the bottom of basin.

At bucket bottom parts upper limb is the staving parts, inwall edge at the staving parts circumferentially is provided with dehydration orifice plate 8 equably, edge is provided with balance ring parts 9 thereon, in the junction of staving parts 7 and bucket bottom parts 5 sealing ring 6 is set, and at the inwall of balance ring parts 9 liquid detergent tipping bucket 1 is set.Among the figure 2 is the filtering mesh bag installing rack, and 3 for guiding current to enter the backwater cover plate of filtering mesh bag.
