Abstract

The invention discloses a washing machine drum, which comprises an outer drum, an inner drum positioned inside the outer drum and a raiser arranged in the inner drum. A clearance is reserved between the inner drum and the outer drum; the upper surface of the raiser is provided with a plurality of drain holes; the inner drum is provided with a plurality of water inlet holes which are communicated with the drain holes of the raiser; and meanwhile, the water inlet holes are communicated with the clearance between the inner drum and the outer drum, so that water in the clearance between the inner drum and the outer drum can flow in the water inlet holes and flow out from the drain holes to shower the water on clothes and improve the washing efficiency of the clothes.

Description

Washing machine drum

Technical field

The present invention relates to a kind of washing machine drum, especially a kind of washing machine drum with lifter.

Background technology

Bucket is by preceding bung in the existing roller washing machine, and back bung and bucket and lifter are formed.When bucket rotated, lifter rose to certain altitude with clothing, and clothing drops at the bottom of bucket owing to conducting oneself with dignity to beat then, and the diameter of bucket is beaten washing in utilizing.

In order to reach the optimal proportion of detergent concentration, water inlet back water level is lower, bucket does not have seldom the part had only in the entry in circular, clothing in being placed in the bucket, rely on to soak and capillarity absorption moisture content soaks, the clothing at the bottom of only being positioned at barrel just is easy to drench, when clothing is a lot of, drenching fully needs long time, makes washing efficiency slow and clean result is relatively poor.

Therefore, need a kind of technical scheme to address the above problem.

Summary of the invention

The present invention seeks to deficiency, a kind of washing efficiency inner tank of washing machine that improves is provided at the prior art existence.

For achieving the above object, inner tank of washing machine of the present invention can adopt following scheme: a kind of washing machine drum, it comprises urceolus, be positioned at the inner core of urceolus and be installed on the lifter of inner core, has the gap between described inner core and the urceolus, described lifter has upper surface and corresponding lower surface, described upper surface is positioned at inner core, and lower surface is installed on the inner core, the upper surface of described lifter is provided with some apopores, described inner core is provided with some inlet openings, this inlet opening is connected with apopore on the lifter, simultaneously this inlet opening with and described inner core and urceolus between the gap be connected.

The present invention is compared with prior art: the upper surface by described lifter is provided with some apopores, described inner core is provided with some inlet openings, this inlet opening is connected with apopore on the lifter, simultaneously this inlet opening with and described inner core and urceolus between the gap be connected, washings in the gap between inner core and the urceolus can be entered from the inlet opening and flow out from apopore, washings can be dashed when putting and drench on the clothes, improve washing efficiency to be positioned at height at lifter.

The specific embodiment

Below in conjunction with the drawings and specific embodiments, further illustrate the present invention, should understand the following specific embodiment only is used to the present invention is described and is not used in and limit the scope of the invention, after having read the present invention, those skilled in the art all fall within the application's claims institute restricted portion to the modification of the various equivalent form of values of the present invention.

See also shown in Figure 1ly, washing machine drum 100 of the present invention comprises urceolus 20, is positioned at the inner core 30 of urceolus 20 and is positioned at inner core 30 and is installed on lifter 40 on the inner core 30.This lifter 40 is provided with in the inner core 30 clothing can be thrown when doing washing for protruding into.In the present embodiment, described lifter 40 is designed to three, and average being arranged in the inner core 30, and so average setting can make clothing constantly be subjected to the impact of lifter 40 and be recycled and throw, to improve the laundry quality.Has gap 21 between described inner core 30 and the urceolus 20.Fig. 1 represents is the state of washing machine drum 100 when being positioned at primary importance.When washing machine drum 100 was positioned at primary importance, one of them lifter 40 was arranged in the minimum point of inner core 30.

See also Fig. 2 and Fig. 3 and in conjunction with shown in Figure 1, described inner core 30 is provided with some inlet openings 31 and extended and be covered in baffle plate 32 on the inlet opening 31.Described baffle plate 32 is for tilting to extend, and this baffle plate 32 extends in the gap 21 between described inner core 30 and the urceolus 20, and described inlet opening 31 is connected with gap 21.

See also Fig. 4 and in conjunction with shown in Figure 5, described lifter 40 has upper surface 41 and corresponding with upper surface 41 and be installed on lower surface (not label) on the inner core 30.Offer apopore 42 on the described upper surface 41.Described lifter 40 is a hollow design, and its inside is provided with the inner chamber 43 that is used for water storage, and described lower surface is provided with the fluting 44 that is connected with inlet opening 31 on the inner core 30, and the cross section of whole lifter 40 is taken the shape of the letter U.

Please consult Fig. 5 again and, when doing washing operation, inject washings W in the washing machine drum 100 in conjunction with shown in Figure 1.Described washing machine drum 100 is positioned at primary importance and rotates along the A of direction shown in Fig. 5.This moment, a lifter 40 was arranged in washings W.In the present embodiment, baffle plate 32 bearing of trends on the described inner core 30 are consistent with the rotation direction B of washing machine drum 100, and the angle that forms acute angle between baffle plate 32 and the inlet opening 31 to be to produce guide function to washings W, make washings W baffle plate 32 stop and guide function under and enter into the inner chamber 43 of lifter 40 from described inlet opening 31.

See also Figure 6 and Figure 7, when washing machine drum 100 when primary importance is rotated and is positioned at the second place, the lifter that injects washings W in the above-mentioned inner chamber 43 is arranged in the peak of inner core 30.Owing to seal between lifter 40 and the inner core 30, washings W can only flow out from the apopore 42 of lifter 40.Washings W flows out and dashes from apopore 42 and drenches on the clothing under the effect of gravity, so, using washing machine drum 100 of the present invention to do washing not only drenches clothing by soaking and can possessing towards the pouring effect faster, thereby can enter washing procedure and rinsing program faster, improve washing efficiency; Simultaneously, when washing, not only can throw clothing and beat clothing, can dash simultaneously and drench clothing, improve washing quality and washing efficiency by lifter 40.
