Abstract

The present invention discloses an automatic washing machine with two asynchronous drum, which comprises a program control system for commanding the washing machine to operate automatically, a driving source providing power for the washing machine, two washing drums driven by the driving source, and pipes for draining liquid out of the washing machine. The two washing drums are arranged one above the other and have workspaces respectively. Further a draining hole connecting to the lower drum work space and a program controllable valve controlling the said draining hole are provided in bottom of the upper drum work space, so that liquid used in the upper drum can be feed into the lower drum. The washing machine according 1;o the present invention enables to reuse water and detergent conveniently, and thus enables to save water effectively and to reduce the environmental pollution due to excessive detergent drainage.

Description

Fully automatic double drum asynchronous washing machine

The utility model relates to a washing machine, in particular to a fully automatic double-drum asynchronous washing machine which can reuse washing water and rinsing water. Background technique

At present, water shortages and environmental pollution have become the focus of attention around the world, so more and more washing machine manufacturers are using advanced technologies that help reduce pollution and save water in the manufacture and design of washing machines. However, the existing washing machines have not been well adapted to the traditional habit of public laundry, and it is not convenient to reuse the washing water and the rinsing water. At present, there is no design that can overcome the above drawbacks as known to the public.

Therefore, it is necessary to design a fully automatic double drum asynchronous washing machine that can easily reuse washing water and rinsing water. Utility model content

SUMMARY OF THE INVENTION An object of the present invention is to provide a fully automatic double-drum asynchronous washing machine which can easily re-use washing water and rinsing water by simply improving the structure of the drum type washing machine based on the existing washing machine manufacturing technology.

In order to achieve the above object, the fully automatic double drum asynchronous washing machine of the present invention is designed in this way:

A fully automatic double drum asynchronous washing machine comprising a program control system for instructing a washing machine to automatically work, a power unit for powering the washing machine, two washing drums driven by the power unit, and a drain pipe for draining the washing machine to the outside. The two washing drums are arranged up and down and each has a working space. The bottom of the working space of the upper washing drum is provided with a drain hole for the working space of the laundry drum and a program-controlled drain valve for controlling the drain hole, so as to use the upper washing drum. The water that has passed through is drained into the lower washing drum.

By using the automatic double-drum asynchronous washing machine of the utility model, nearly 50% of water and detergent can be saved during washing, thereby saving the use of fresh water more effectively and reducing the detergent The amount of emissions to the environment. DRAWINGS

Hereinafter, the specific embodiments of the present invention will be further described in detail with reference to the accompanying drawings:

BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a cross-sectional view showing a top view of a fully automatic double drum asynchronous washing machine of the present invention. detailed description

Referring to Fig. 1, the fully automatic double drum asynchronous washing machine 7 of the present invention comprises an upper washing drum 1 and a lower washing drum 2 arranged up and down in a vertical direction. The upper and lower laundry drums 1 and 2 are driven by two motors or by a motor by a clutch to be able to operate asynchronously. The upper part of the working space of the upper washing drum 1 and the lower washing drum 2 is provided with a water inlet opening for tap water, so that the upper washing drum 1 and the lower washing drum 2 can work synchronously when the washing water and the rinsing water are not required to be reused. Or work alone.

The bottom of the working space of the upper washing drum 1 is provided with a drain hole 3 and another drain hole 4 for closing the drain pipe 5. When it is necessary to reuse the washing water and the rinsing water, the program control valve opens the drain hole 3, so that the used water of the upper washing drum 1 is discharged into the working space of the lower washing drum 2, so that the lower washing drum 2 is discharged. The incoming water washes the laundry; when it is not necessary to reuse the washing water and the rinsing water, the program control valve opens the drain hole 4 to discharge the used water of the upper washing drum 1 directly to the outside.

The standard laundry amount of the washing machine 7 is shared by the upper and lower washing drums 1, 2, for example, when the washing machine 7 has a washing capacity of 6 kg, the washing amount of the upper washing drum 1 and the lower washing drum 2 is 3 kg.

When the washing machine 7 is used, the laundry to be washed first is put into the upper washing drum 1 , and the laundry to be washed is put into the lower washing drum 2;

During the operation of the washing machine 7, the upper washing drum 1 works one step earlier than the lower washing drum 2, that is, after the upper washing drum 1 completes each washing and rinsing, the program control valve opens the drain hole 3 in time to use the upper washing drum 1 The water drains into the working space of the lower laundry drum 2 The lower washing drum 2 then washes the laundry with the drained water.

After the upper washing drum 1 completes the first washing and dehydration, the lower washing drum 2 can follow the upper washing drum 1 to work simultaneously according to the program instruction; and after the lower washing drum 2 completes each washing and rinsing, passes through the drainage hole 6 drain.

The performance advantages of this automatic double-drum asynchronous washing machine 7 are as follows:

(1) Reuse of wash water and rinse water to save nearly half of water and detergent;

(2) It is convenient to wash underwear and outerwear, silk sweater and ordinary clothes, clean clothes and dirty clothes separately according to different washing methods, and also can eliminate 4 bars of various clothes and put them together and wash them separately. Worthy of the trouble of starting the washing machine;

(3) The upper washing drum 1 or the lower washing drum 2 can be used separately as a small washing machine, so that a small amount of laundry can be washed at any time.

This design has three main advantages:

First, the practical environmental effects.

Washing water accounts for about one-third of the domestic water consumption of urban residents, accounting for about 1/2 of the domestic water consumption of rural households. If this design product can be promoted and used, the lack of water resources in China will be greatly alleviated; The large amount of emissions is an important cause of water pollution. Advocating the use of high-price, low-pollution detergents is not binding on the public, and it is better to comply with the public's frugal habits to reduce the level of environmental pollution.

Second, extensive compatibility.

This design does not exclude all the advanced technology results used in the current drum-type washing machine manufacturing, and it is easy to achieve perfect grafting with these results and various excellent design concepts in the future.

Third, the humanized design concept.

The design product is both convenient and easy to operate. The user can start the washing machine to take out the clothes to be dried, without any manual operation, and it is as convenient as using other fully automatic washing machines.
