Description

A device for reversing and clutching and an external force-action washing machine made of it

technical field

The invention belongs to the technical field of home appliances, and in particular relates to a device for reversing and clutching of a washing machine and an external force-acting washing machine with the device.

Background technique

Life lies in exercise. The survey shows that 340 million urban and rural residents in my country have participated in physical exercise. According to the standard of "regular participation in physical exercise" (participate in 3 times a week or more, each exercise lasts for 30 minutes or more, and each exercise According to statistics, the proportion of people who "regularly participate in physical exercise" in the country reaches 28.2%. This ratio shows that my country already has a relatively stable group of people who regularly participate in physical exercise, which objectively reflects the basic situation of urban and rural residents participating in physical exercise. In terms of exercise items, 62.0% of the residents choose fitness walking and running, followed by ball games, aerobics, cycling, martial arts, swimming, etc. The exercise items show a trend of diversification. In the choice of fitness places, there is a more obvious feature of "nearby" exercise. In addition, the proportion of residents exercising in fee-paying sports venues has increased, the level of sports consumption has gradually increased, and the content of consumption is mainly "in-kind" consumption. 72.7% of the people who exercise have consumed sports, and the per capita consumption is 593 yuan. This shows that many people do not have enough time to participate in exercise these days, and there is also a large expenditure among the exercising population. In this case, many people choose to go out for exercise, and some people choose to use the fixed rest time to go to some fitness places for exercise every day. These exercise methods are only used for exercise alone, which is not very good. Make full use of this time and energy, and must set aside a part of the time in the family to wash clothes. If there is a fitness and energy-saving laundry equipment that combines fitness and laundry, it can save energy and save time, clean clothes, and be environmentally friendly, which just meets the needs of modern social development.

The laundry method of washing alone can be completed with the above water inlet button and drain button, and the washing method of independent dehydration can be completed by pedaling directly, and the washing and dehydration time are displayed on the time display window at the same time.

It is also possible to use the operation program without power distribution (without installing water inlet valve, electric drain valve, water inlet switch, drain switch, water level switch, etc.), and the laundry process can also be completed: see Figure 6 and Figure 10, the rectangle in Figure 10 indicates The operation panel and circle with dots represent the drain knob, the dotted line graph represents the drain swing arm, the vertical state of the drain knob indicator sign indicates that the drain valve is in the water sealing state, and the horizontal state of the drain knob indicator sign indicates that the drain valve is in the drain state; in the washing machine The side panel 1 is provided with a drainage swing arm 502 and a drainage knob 501 (the same as the drainage method of a double-tub washing machine). Required water level → wire drawing 20 (in a relaxed state) hang on the washing hook 37, step on the pedal 7 of the washing machine to start washing until the required time → turn the drainage knob 501 indicator to indicate the "drainage" position (the drainage knob 501 drives the drainage swing arm 502, the drainage The swing arm 502 drives the drain bar 503, the drain bar 503 pulls the drain valve core), the drain valve drains water for a period of time → the drawing wire 20 (in a tensioned state) is hung on the dehydration hook 38, and the washing machine pedal 7 starts dehydration for a period of time →Repeat the above procedure for rinsing.

The above-mentioned embodiments can be changed without departing from the scope of the present invention. Therefore, the structures included in the above description and shown in the drawings should be regarded as illustrative rather than limiting the protection scope of the patent application.
