Description

A kind of washing machine inner tub

The present invention relates to a kind of washing machine inner tub, and especially can be at an upper portion thereof and have the interior bucket of the washing machine of even friction effect between the bottom.

As depicted in figs. 1 and 2, bucket is placed in the washing machine shell in a kind of washing machine (Japan Patent open NO.4-19789) conventional, and this barrel made by stainless steel as washing and spin dryer tube (being called " interior barrel " hereinafter) 1.

Interior bucket 1 comprises that one is used for installing the ring 1a of a fluid balance device, a cylindrical body 1b who forms the staving part and a base plate 1c who forms the bottom thereon on top.On the inner surface of interior barrel 1 staving 1b, on the whole height of interior bucket 1, spread all over the protruding button 2 that the inwardly protruding same size is arranged.A pulsator 3 can be rotatably set on the base plate 1c.

When a motor (not shown) rotates pulsator 3 and when producing the turbulent fluctuation of washings and clothing pivotally, between the clothing, between clothing and the pulsator 3 and the friction effect between clothing and the protruding button 2 realized cleaning function.

Yet, in the washing machine of such routine,, thereby have non-homogeneous washing problem owing to the top of interior bucket 1 and the non-homogeneous friction effect between the bottom during the washing.This is because there is the friction between the inwardly protruded protruding button 2 on the inner surface of friction between the clothing that the turbulent fluctuation of the direct friction of pulsator 3 and clothing, the washings that produced by pulsator 3 causes and clothing and interior bucket 1 in the bottom of interior bucket 1, and does not have the friction a little less than reaching relative between protruding button 2 and the clothing between the direct friction of pulsator 3 and the clothing on the top of interior bucket 1.In brief, in the washing machine of routine, because the top of interior bucket 1 and the non-homogeneous friction effect between the bottom may expect to have uniform clean result and uniform rate of depreciation hardly.

The purpose of this invention is to provide the washing machine inner tub that can have even friction effect.

Another object of the present invention provides the interior bucket with simplified structure.

These and other objects are to realize by on the inner surface of interior bucket so protruding button being set: promptly, have the protruding button that successively decreases gradually and the friction effect between the clothing from top to the bottom of interior bucket.Bucket comprises a staving and a base plate in of the present invention, and staving has the crimping that is integrally formed in its top, so that a fluid balance device to be installed thereon.

Figure 13 is the profile of an osculum on the interior bucket staving of the present invention.

What Fig. 3 showed is a washing machine of the present invention, it comprises a shell 8 that surrounds the whole washing machine, be not equipped with a top cover 6 on the top of shell 8, top cover 6 has a control panel 7 that is used to operate washing machine, hanging bucket 11 outside in shell 8, outer bucket 11 is supported by a plurality of snuff bars (snuff bar) 9 and a plurality of damping spring 10.

Bucket 5 in one is arranged in the outer bucket 11, and it is not only as washtub but also as spin dryer tube, and interior bucket 5 is connecting a clutch 12 that transmits energy and underspeed.Bottom in interior bucket 5, be provided with a pulsator 17, pulsator 17 is rotated by a motor pulley 14 pivotally by a drive motors, and a belt 16 is connecting motor pulley 14 and a clutch pulley 15, and clutch pulley 15 is connected with clutch 12.Top at interior bucket 5 is provided with a fluid balance device 4, is used to adjust the inclination of the interior bucket 5 that is caused by clothing during washing and drying.And be provided with a filter 18, be used for collecting a small amount of thread of water circulation.Outside the bucket 11 below, be mounted with a draining valve 19 and a scupper hose 20.

As shown in Figure 3 and Figure 4, bucket 5 comprises that one has the cylindrical shape staving 5a of an inner surface, the protruding button 5c, the 5e that form and osculum 5f, and base plate 5b thereon in the stainless steel, base plate 5b has a wheel hub 21 that is connected in base plate 5b from below, and clutch 12 is fixed and supported thereon.

As Fig. 4 and shown in Figure 11, the inner surface of the staving 5a of interior bucket 5 comprises a plurality of inside protruding buttons that diminish gradually to bottom shape from the top, to produce the friction effect that weakens gradually.

In addition, although not shown, as an alternative embodiment of the invention, the inner surface of the staving 5a of interior bucket 5 can comprise a plurality of protruding buttons according to same size inwardly sparse gradually protruding button that distributes from the top to the bottom, to produce the friction effect that weakens gradually.In addition, the inner surface of the staving 5a of interior bucket 5 comprises the protruding button 5e of a plurality of oval-shaped reinforcements and a plurality of osculum 5f, protruding button 5e forms ellipse with the direction from the top to the bottom as shown in figure 10, and osculum 5f is formed between protruding button 5c, the 5e (as shown in figure 13) by burring.

As Fig. 6 and shown in Figure 12, on the inner surface of the staving 5a of interior bucket 5, to be provided with the conjugate foramen 5h of a plurality of squares and circular filter 18 and longly to lead tip 5g, during washing, to catch and to collect thread from the top to the direction of bottom.

At the top of interior barrel 5 staving 5a, by a plurality of screw 5m that a fluid balance device 4 is fixed thereon, and as shown in Figure 7, the top edge of staving 5a is ended by forming a bead portion 5i, to strengthen top and to make it to be easy to engage fluid balance device 4.

As shown in Figure 8, by rolling volume a slice stainless steel and two ends are engaged, and form columnar staving 5a itself by smooth joint 5k.

On the other hand, shown in Fig. 5 (A) and 5 (B), the base plate 5b of interior bucket 5 has a hole 5t who is formed on base plate 5b central authorities, and the peripheral 5u of hole 5t constitutes in order to strengthen with step.On the periphery of base plate 5b, the projection 5d that is formed with a plurality of circles also is formed with a plurality of screw hole 5s to engage the lower end of filter 18 to prevent the inclination of clothing.

Between the middle body and peripheral part of base plate 5b, be formed with the chamber 5r of a plurality of definite sizes and definite degree of depth, in order to reinforcement base plate 5b, and in the 5r of chamber, be formed with a plurality of wheel hub conjugate foramen 5p and a plurality of osculum g that are used to drain washings that are used for wheel hub 21 is connected in base plate 5b.

As shown in Figure 9, the periphery of the lower limb of whole staving 5a is engaged 51 with the top edge of base plate 5b by smooth, and staving 5a is engaged with the base plate 5b of interior bucket 5.

In washing machine of the present invention, the pulsator that rotates pivotally 17 by bucket 5 bottom in being placed in when washing mode drives washing.Because at the stronger turbulent flow of bottom and the friction effect of pulsator wheel blade, the friction effect of the bottom (pulsator is placed in this) of interior bucket is better than top.In the present invention, a plurality of less protruding button 5c are formed on the bottom (friction effect is stronger) of staving 5a herein, and a plurality of bigger protruding button 5c are formed on the top (friction effect is weak) of the staving 5a of interior bucket 5 herein, thereby form a uniform friction effect on the whole height of interior bucket 5.

In addition, the intensity of bucket 5 in oval-shaped protruding button 5e keeps during drying at a high speed.And the round bump 5d in being formed on the base plate 5b of bucket 5 prevents the inclination of the clothing on the circular surface of base plate 5b during washing, thereby increases clean result.While is compared with the interior bucket of the routine of three types, and bucket has the advantage that cost reduces in two types of the present invention.

Although the present invention is described together with its special embodiment, knows those skilled in the art significantly and can make many replacements and change according to the description of front.Therefore, the present invention is intended to comprise spiritual essence that all fall into the accompanying Claim book and modification and the replacement in the scope.
