Environmentally friendly water-waving washing machine and water draining method thereof

Abstract

The invention discloses an environmentally friendly water-waving washing machine and a working method. The environmentally friendly water-waving washing machine comprises an inner tub and an outer tub, wherein the inner tub is concentrically installed in the outer tub, the inner tub is a whole water storage tub, a water draining valve is arranged at the lower portion of the inner tub, and a controller for turning on and off the water draining valve is arranged at the corresponding position of a water draining valve at the lower portion of the outer tub. The controller is not in contact with the water draining valve, and the controller and the water draining valve controls turning on and off of the water draining valve under the effect of a non-contact force. The washing machine saves water by 20% or above, can also effectively prevent secondary clothes contamination and is simple in structure and good in reliability, and seal links are few.

Description

technical field [0001] The invention relates to the field of washing machines, in particular to an environment-friendly water-saving washing machine and a drainage method thereof. Background technique [0002] Fully automatic washing machines are composed of an inner tub and an outer tub set together. The bottom of the outer tub is connected with a deceleration clutch. The pulsator shaft and the dehydration shaft of the deceleration clutch are respectively connected with the pulsator and the inner tub. The inner tub is provided with lateral drainage holes. , Therefore, the water between the inner bucket and the outer bucket is connected, that is, the liquid level is the same, the water between the inner bucket and the outer bucket has no effect on the clothes, and nearly 20% of the water is wasted during the entire washing process, and the most important point, The water in this space also has the problem of secondary pollution of clothes, because there is moisture and dirt ...

AI Technical Summary

Problems solved by technology

[0002] Fully automatic washing machines are composed of an inner tub and an outer tub set together. The bottom of the outer tub is connected with a deceleration clutch. The pulsator shaft and the dehydration shaft of the deceleration clutch are respectively connected with the pulsator and the inner tub. The inner tub is provided with lateral drainage holes. , Therefore, the water between the inner bucket and the outer bucket is connected, that is, the liquid level is the same, the water between the inner bucket and the outer bucket has no effect on the clothes, and nearly 20% of the water is wasted during the entire washing process, and the most important point, The water in this space also has the problem of secondary pollution of clothes, because there is moisture and dirt that cannot be removed between the inner bucket and the outer bucket, which is easy to breed bacteria and mildew. During the washing process, the water between the inner bucket and the outer bucket flows into the inner bucket , the pollutants are also brought into the inner barrel, and the secondary pollution is quite serious

[0003] There is also a bucket washing structure, which can solve the above problems, but the current bucket washing structure is an inner bucket connected in sections, and the bottom of the outer bucket is welded or screwed to a special-shaped sealing chamber, and a sealing ring is installed in the sealing chamber , there is a drain port on the outside of the sealed chamber, which realizes the connection of the water in the inner barrel with the drain valve outside the outer barrel, controlled by the drain valve, closing the drain valve when washing, and developing a drain valve when dehydrating. There is a problem here is the reliability of the mechanical seal Not good, there are many links that need to be sealed, and the reliability is not good. After the machine runs for a period of time, the seal will fail

Once the mechanical seal is damaged, the machine cannot work normally

[0004] The existing patent literature (application number 201520076912.7 and application number 201510171392.2) mentions a drainage control valve. A self-locking mechanism is set in the valve body to realize the drainage function of the inner barrel. The shape of the groove is not well designed, and the action of the motor is used. Due to the guiding effect of the groove and the effect of gravity, the power-on time of the motor needs to be accurate. On this basis, an environment-friendly water-saving washing machine that does not require positioning and reduces the impact generated by positioning is proposed.
