Description

Washing machine laundry dewatering tank steering structure

Technical field

The invention relates to a washing machine, in particular to a washing and dewatering tank steering structure of a washing machine.

Background technique

The washing and dewatering tank of the horizontal type washing machine is horizontally placed, and the rolling of the inner tank body of the washing and dewatering tank is used, so that the clothes are continuously thrown high and fall in the washing and dewatering tank, like the action of smashing and beating during hand washing, and It achieves the effect of cleaning clothes and is less likely to damage the clothes. Moreover, the horizontal drum type washing machine does not fill the washing and dewatering tank with water. Therefore, compared with the vertical type washing machine, the horizontal tube type washing machine has the advantages of water saving and the clothing is not easily deformed and broken.

However, in the dehydration stage, since the laundry dewatering tank of the conventional horizontal type washing machine is horizontally disposed, the laundry in the laundry dewatering tank is concentrated in the lower portion, and if the laundry weight is heavy or the quantity is large, the inner tank of the laundry dewatering tank is super-high speed. When rotating, the clothes in the laundry dewatering tank are not evenly distributed along the ventral side, and the centrifugal effect is uneven, which results in poor dehydration effect, causing the body to sway, generating more noise, and making the internal components of the washing machine more susceptible to damage.

Therefore, the inventors believe that the conventional horizontal type washing machine has a need for improvement.

detailed description

The construction, features, and embodiments of the present invention will be described in the following by means of the accompanying drawings.

Referring to FIG. 2, in conjunction with FIG. 1, the present invention relates to a washing and dewatering tank steering structure for a washing machine, comprising a casing 1 and a washing and dewatering tank 2 from the outside. The housing 1 is provided with an outer cover 10 for opening to place the laundry to the laundry dewatering tank 2, and is closed to prevent the inadvertent intrusion or foreign matter from falling in the washing machine; the laundry dewatering tank 2 The opening is provided with a sealing cover 20 for opening to be placed into the laundry, and closed to prevent laundry and sewage from leaking out of the laundry dewatering tank 2. Each of the two sides of the washing and dewatering tank 2 is provided with a plurality of pivoting mechanisms 3, and each of the pivoting mechanisms 3 includes a fixing frame 31, and the fixing frame 31 can be fixed at any position in the casing 1. As shown, the holder 31 is triangular and fixed to the bottom of the housing 2 to provide better support for the laundry dewatering tank 2.
