Problems solved by technology

[0005] The double cylinder washing machine has a high center of gravity and is unstable, so the requirements for vibration are higher. The greater the overall mass of the washing machine, the smaller the vibration. Setting multiple drainage pumps or multiple washing devices to drain water at the same time will affect the The barrel with a high center of gravity produces greater vibration and noise, which brings unnecessary troubles to daily life

Embodiment 1

[0034] Such as figure 1 As shown, the multi-tub washing machine is provided with multiple washing devices, and each independent washing device can independently perform water intake, washing, drainage, spin-drying, rinsing, draining, and spin-drying processes on clothes. To achieve the purpose of washing clothes. The multi-tub washing machine in this embodiment has a double drum washing machine structure, and the washing devices are a first washing tub 1 and a second washing tub 2 respectively. The first washing tub 1 and the second washing tub 2 can respectively and independently perform the optimization of the clothes in sequence. The first washing tub and the second washing tub can also be respectively equipped with a drying device to perform the drying process after the dehydration process. , To achieve the purpose of drying the clothes in the first washing tub and / or the second washing tub. Preferably, the washing machine can also heat the washing water, the first washing...

Embodiment 2

[0037] Such as figure 2 with image 3 As shown, the multi-tub washing machine in this embodiment has a double-tub washing machine structure. The double-drum washing machine has two washing devices, a first washing device and a second washing device. The multi-tub washing machine is a double-drum washing machine. The washing device is the washing drum. A drainage pipe is respectively connected to the bottom of the first washing device and the second washing device, and the other ends of the two drainage pipes are respectively connected to a drainage main pipe communicating with the outside. A drain valve is provided in the middle of the drain pipe, the first washing device is connected with the drain valve A, the second washing device is connected with the drain valve B, and a drain pump P is provided on the drain main pipe. The washing water of the first washing drum and the second washing drum of the multi-tub washing machine flows through the drain pipe and the drain main pi...

Embodiment 3

[0040] Such as Figure 4 Said, the drainage method of the multi-tub washing machine in this embodiment, the multi-tub washing machine includes at least two sets of washing devices and a drainage pump communicating with the outside, and a drainage pump is provided between each washing device and the drainage pump. Valve, each washing device of the multi-tub washing machine drains water in order. Once the washing device drains, first close the drain valve of the washing device, and then close the drain pump;

[0041] Detect whether there are other washing devices that need to be drained. If so, first open the drain valve of the washing device that needs to drain, and then turn on the drain pump to drain the washing device. If not, the multi-tub washing machine drains. When a washing device is draining water and other washing tubs are waiting for the draining process, the water and clothes in the other washing tubs act as counterweights, which can increase the weight of the washing m...

Abstract

The invention relates to a drainage method for a multi-tubular washing machine. The multi-tubular washing machine includes at least two sets of washing devices and a drain pump communicating with the outside world. A drain valve is respectively arranged between each washing device and the drain pump. The multi-tubular washing machine Each washing device of the drum washing machine drains water in sequence. Once the washing device is drained, first close the drain valve of the washing device, and then turn off the drain pump; check whether there are other washing devices that need to be drained, and if so, first open the washing device that needs to be drained The drain valve of the washing machine is opened, and then the drain pump is opened to drain the washing device. If not, the draining of the multi-tubular washing machine is completed. The invention can control each washing device to discharge water sequentially, reducing the vibration of the washing machine during the drainage process; and by controlling and judging the working sequence of the drainage pump, the washing water in the multi-tubular washing machine can be completely discharged, prolonging the life of the washing machine. The invention has simple structure, low cost and is suitable for production and popularization.

Description

Technical field [0001] The invention relates to the field of washing machines, in particular to a drainage method of a multi-tub washing machine. Background technique [0002] Currently, most drum washing machines on the market have only one washing tub. With the strengthening of people's awareness of hygiene, more and more users need to wash different types of clothes separately or wash a small amount of clothes in time. [0003] With the improvement of people's quality of life, hygiene awareness has gradually increased, especially in the washing of household clothes, more and more people wash clothes separately. If the existing washing machine is used for multiple washing, the washing time is difficult to meet the requirements; if two or more washing machines are purchased separately and washed at the same time, it will not only cause a great waste of energy and water resources, but also occupy a large space. Not suitable for family use. Therefore, the multi-tub washing machin...
