Problems solved by technology

These molds are caused by a large amount of dirt accumulated inside the washing machine that has been used for a long time and cannot be effectively removed to breed and reproduce. If the dirt that is invisible to the user is not removed, the bacteria will adhere to the clothes again after the next wash. Brought to the human body, causing the problem of cross-infection in laundry
[0006] In addition, since the lint floats in the water when the washing machine is washed, using the existing drainage method, the water is discharged from the lower part of the inner tub, and finally the lint will remain on the clothes, affecting the washing effect of the clothes

Embodiment 1

[0044] Such as Figure 4 As shown, there is no water outlet hole in the area between the position corresponding to the maximum water intake and the bucket bottom 32 on the bucket body 31 described in this embodiment, and a water outlet hole 33 is provided in the area between the bottom of the balance ring 7 and the position corresponding to the maximum water intake. The outer barrel 2 below is provided with a driving device 8, and the driving device 8 is connected with the inner barrel 3 and the pulsator 4 through its drive shaft 81.

[0045] The bucket body 31 and the bucket bottom 32 described in this embodiment are separate structures, and the two are sealed.

Embodiment 2

[0047] The difference between the present embodiment and the first embodiment is that the bucket body 31 and the bucket bottom 32 are integrally structured.

Embodiment 3

[0049] Such as Figure 5 As shown, the inner barrel 3 described in this embodiment has a circular frustum structure with a large opening at the top and a small opening at the bottom.

[0050] Alternatively, the angle α between the peripheral wall of the inner tub 3 and the vertical direction is 0-4°, preferably α is 1°-2°.

Abstract

The invention discloses an impeller full-automatic washing machine comprising an external barrel, an internal barrel disposed in the external barrel and an impeller disposed in the internal barrel. A drainage port is arranged on the bottom of the external barrel; the washing machine does not have a draining valve; the drainage port of the external barrel is directly communicated with a drain pipe; during washing and rinsing, washing water is only accommodated in the internal barrel and the external barrel contains no washing water; during dehydration, the washing water passes through the external barrel, the external barrel drainage port and the drain pipe from the upper part of the internal barrel and then is directly discharged; during water inlet, water is only charged into the internal barrel; after washing is finished, the internal barrel is driven to rotate at high speed to produce centrifugal force; water in the internal barrel and water in the clothes spirally rise and are discharged out of the external barrel via water discharging holes of the internal barrel; and the water can be directly discharged via the drain pipe. Without the draining valve, assembling technology of the external barrel components can be reduced, installation space of a barrel bottom driving device can be increased and cost can be reduced.

Description

technical field [0001] The invention relates to the field of washing machines, in particular to a fully automatic washing machine, especially a pulsator type fully automatic washing machine without a drain valve. Background technique [0002] Existing pulsator washing machines, such as figure 1 As shown, it generally includes a pulsator 1', an inner barrel 2', an outer barrel 3' and a box body 4' arranged in sequence from the inside to the outside, wherein the pulsator 1' is arranged at the bottom center of the inner barrel 2' and can be driven by a driving device 5 ' Drive the rotation. The top of the inner tub 2' is provided with a balance ring 6', and the side wall of the inner tub 2' is longitudinally provided with multiple rows of dewatering holes 21', and the bottom of the inner tub 2' is provided with a drain hole 22', which is also The output shaft 51' of the driving device 5' is passed through. Such as figure 2 As shown, an air chamber 31' and a water level sen...
