The utility model content

The purpose of this utility model provides a kind of washtub of rotary drum washing machine, under the situation that does not change existing rotary drum washing machine capacity, only washtub being improved just to make a washing machine have big capacity and these two characteristics of low capacity concurrently, both can do washing with big and bigger capacity, can wash smallclothes clothings such as sock and glove again where necessary with the most rational water consumption separately as the conventional wave wheel washer.

For realizing purpose described in the utility model, the utility model proposes a kind of rotary drum washing machine washtub, the washtub that it is characterized in that this rotary drum washing machine is to be made of outer washtub and two washtubs of interior washtub that can install and remove, promptly impeller and outside the interior washtub that can install and remove is installed between the washtub, washtub is the tubulose at the bottom of not having barrel in this, its bottom circumference is grown up than impeller periphery but is littler than girth in the outer washtub, its lower end is tightly connected with sealing ring and outer washtub bottom, load onto washtub in this, just become the washing machine of a low capacity, the heap(ed) capacity of this low capacity washtub is designed to be equal to or less than the minimum capacity of outer washtub.When needs washing smallclothes clothing or a small amount of clothing, install washtub in this, only need very a spot of water just can finish washing; After washtub was pulled down taking-up in this, the big capacity that can recover outer washtub again was used to wash bigger with a large amount of clothings.This has just overcome the restriction of minimum washing capacity to existing rotary drum washing machine, and using water wisely and reasonable use of water have to greatest extent enlarged the purposes of washing machine.

The utility model will be illustrated in conjunction with the accompanying drawings by embodiment.

Fig. 2 is the A-A part sectioned view of the utility model accompanying drawing 1

Fig. 3 is the generalized section of the groove decorative cover that uses with groove fit shown in the utility model accompanying drawing 1

Fig. 4 is an another kind of structural representation of the present utility model

Among the figure: 1. washtub 3. impellers 4. sealing rings 5. water seal axles 6. groove decorative covers in the outer washtub 2.

The specific embodiment

Accompanying drawing 1 is the structural representation of the said rotary drum washing machine washtub of the utility model.For brevity, the do not draw other parts of washing machine such as power transmission, control, intake-outlet, shell, cover etc. of this figure.As can be seen from the figure, outer washtub 1, impeller 3, water seal axle 5 etc. all with the conventional wave wheel washer mutually roughly the same, but there is a groove bottom of washtub 1 around impeller 3 outside, interior washtub 2 and the sealing ring 4 that can install and remove is installed in the groove, sealing ring 4 is installed in presses close to impeller 3 these sides in the groove, utilize this sealing ring 4 can realize being tightly connected of interior washtub 2 and outer washtub 1 bottom, and interior washtub 2 can be easy to carry out dismounting.But the base girth of interior washtub 2 is greater than the outer perimeter of impeller 3 less than the interior girth of outer washtub 1, so the volume of interior washtub 2 is just less than the volume of outer washtub 1.For the purpose that realizes economizing on water, the heap(ed) capacity of washtub 2 is equal to or less than the minimum capacity of outer washtub 1 in the design.Interior washtub 2 is pulled down rearward recess can leaving space, can groove be covered with the groove decorative cover shown in the accompanying drawing 36, just can not influence the use of outer washtub 1.

Accompanying drawing 2 is the A-A part sectioned views in the accompanying drawing 1, a key shape tenon is arranged the bottom of interior washtub 2 as can be seen in conjunction with this section, a keyway shape recess cooperation on the bottom groove of it and outer washtub 1, it can play the role of positioning, and staving was along peripheral tangential direction rotation displacement when it can also prevent washing clothes when interior washtub 2 is designed to rotary body.When interior washtub 2 is not rotary body, can be with also can this tenon and the design that cooperates of recess.

When specifically implementing washing clothes, interior washtub 2 is installed at the end of outer washtub 1, because the sealing function of sealing ring 4 is arranged, just formed the washing machine that a heap(ed) capacity is equal to or less than the low capacity of outer washtub 1 minimum capacity, can wash smallclothes clothing or small amount separately; Interior washtub 2 is taken out, add groove decorative cover 6, just revert to the big capacity of outer washtub, can wash big part or a large amount of clothings.

Accompanying drawing 4 is another kind of structural representations of the present utility model, and interior washtub 2 is rotary bodies among the figure, and its bottom internal thread and outer cylindric washer 1 bottom center on the external thread rotary stressed joint of impeller 3 and be pressed on the sealing ring 4 that is installed in outer washtub 1 bottom.Impeller 3 and sealing ring 4 do not have the groove at the bucket end of the sort of structure shown in the accompanying drawing 1 all above the bottom surface of outer washtub 1 among the figure, and this structure does not just need to do the groove decorative cover.The interior washtub 2 of this structure also is easy to dismounting, is the same with the effect of structure shown in the accompanying drawing 1.

From accompanying drawing as can be seen, the utility model said impeller 3 and outside install between the washtub 1 in washtub 2 this designs be subjected to impeller 3 and outside distance limit between the washtub 1, promptly the size of interior washtub 2 should satisfy this basic demand of minimum capacity that its heap(ed) capacity is equal to or less than outer washtub 1.If the impeller diameter is excessive, washtub in just can not be between impeller and washtub installing again, otherwise the interior washtub of making is will capacity excessive and do not have a meaning of economizing on water.

For the straightforward of drawing, outer washtub 1 shown in the accompanying drawing and interior washtub 2 are the rotation body structures with axial symmetry, but in fact might not require outer washtub 1 and interior washtub 2 to make same axially symmetric structure, outer washtub 1 and interior washtub 2 can be that rotary body can not be a rotary body also.The utility model is described with the base girth rather than with diameter when the relative size of the outer washtub 1 of narration, interior washtub 2 and impeller 3, is exactly because of this reason.According to the design needs, washtub can be designed to the smooth connection body of rotary body and non-rotary body, the junction, bottom that is washtub is that rotary body and top washing part is a non-rotary body, perhaps the junction, bottom of washtub is designed to non-rotary body and top washing part is a rotary body.As long as can carry out dismounting easily, the heap(ed) capacity of washtub is equal to or less than this basic demand of minimum capacity of outer washtub in can satisfying simultaneously, and above-mentioned several designs can be selected for use flexibly.
