Problems solved by technology

In addition, if the deviation of the laundry is large, the centrifugal force of the rotary drum during rotation will increase, and since the rotation requires a large torque, it will not be possible to start the dehydration operation.

[0036] Hereinafter, one Embodiment of this invention is described in detail based on drawing.

[0037] figure 1 It is sectional drawing which shows typically the structure of the washing machine 1 which concerns on this embodiment. figure 2 It is an operation explanatory diagram which shows the longitudinal cross section of the part of the washing machine 1 of this embodiment.

[0038] The washing machine 1 of the present embodiment is suitable for use in, for example, laundromats and households, and includes a washing machine body 1a; a washing tub 1b including an outer tub 3 and a drum 2 having an axis S1 extending substantially horizontally; and a water injection device 1c , has a water receiving unit 5 and a nozzle unit 6; a driving device 40; a control unit not shown.

[0039] figure 1 The shown washing machine main body 1a has a substantially rectangular parallelepiped shape. On the front surface 10a of the washing machine main body 1a, an opening 11 for taking and ...

[0060] image 3 It is sectional drawing which shows typically the structure of the washing machine 1 which concerns on 2nd Embodiment of this invention. Figure 4 It is an operation explanatory diagram which shows the longitudinal cross section of the part of the washing machine 1 of this embodiment.

[0061] The washing machine 1 of the present embodiment includes a washing machine main body 1a; a washing tub 1b including an outer tub 3 and a drum 2 having an axis S1 extending substantially horizontally; a water injection device 1c including a water receiving unit 5 and a nozzle unit 6; and a driving device 40; A control unit (not shown) is the same as the above-described first embodiment in these points.

[0062] image 3 The washing machine main body 1a shown is configured in such a way that the front surface 10a thereof faces slightly upward, whereby the opening 11 for taking and placing laundry with respect to the drum 2 is formed obliquely upward, and the user can open...

no. 3 approach

[0069] The washing machine 1 of the third embodiment of the present invention, such as Figure 5 As shown, the axis S1 direction of the washing tub (drum) 1b extends in a substantially vertical direction, and the present invention is applied to a washing machine 1 called a so-called vertical fully automatic washing machine.

[0070] In such a vertical fully automatic washing machine 1 , a pulsator (stirring blade) 4 is rotatably arranged in the center of the bottom portion 2 c of the drum 2 . like Figure 5 As shown, the pulsator 4 is a normal pulsator having a substantially disk-shaped pulsator body and a plurality of fin portions formed on the upper surface of the pulsator body. Such a pulsator 4 agitates the wash water stored in the tub 3 to generate a water flow.

[0071] The drive device 40 such as Figure 5As shown, the drive shaft 17 extending toward the bottom 2c of the drum 2 is rotated by a motor (not shown) as the main body to provide driving force to the drum 2 ...

Abstract

The object of the present invention is to provide a washing machine that can avoid the deceleration or stop of the rotation of the washing tub even if there is deviation of the laundry in the washing tub, and can eliminate the unbalance of the washing tub reliably and quickly during the spin-drying operation. Can effectively avoid the delay of running time. The lifting rib (7) as a balancer of the washing machine (1) of the present invention is equipped with: a partition (71), which can be adjusted by suppressing the injection from the top (1d) side of the washing tub (1b) by the water injection device (1c). The flow of water (W) towards the base end (1e) side makes the adjustment water (W) stagnate on the top end (1d) side; and the outlet part (72) can discharge the injected adjustment water (W) from the washing tub (1b ) is discharged from the proximal side (1e).

Description

technical field [0001] The present invention relates to a washing machine with dehydration function. Background technique [0002] Washing machines installed in general households, laundromats, etc. have a washing-dehydrating function and a washing-dehydrating-drying function. [0003] A washing machine with a spin-drying function generates vibration and noise due to the displacement of the laundry in the rotating drum. In addition, when the deviation of the laundry is large, the centrifugation of the rotating drum during rotation becomes large, and since a large torque is required for the rotation, the spin-drying operation cannot be started. In order to eliminate this, the user stops the operation of the washing machine and manually eliminates the drift of the laundry. [0004] In order to eliminate such cumbersome work, when it is determined that the magnitude of the unbalance, which is the deviation of the laundry, is larger than a predetermined value, the rotating dru...
