Problems solved by technology

[0006] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art, and provide a method for controlling drainage of a clothes treatment device and a multi-tube clothes treatment device, which solves the problem that other washing The washing water in the tub flows back into the washing tub, causing the problem of clothing contamination, especially avoiding the washing water in the upper washing tub being poured back into the lower washing tub when the washing tubs arranged up and down are performing drainage or dehydration work question

Embodiment 1

[0040] Such as Figure 1 to Figure 3 As shown, this embodiment discloses a method for controlling drainage of a laundry treatment device. The clothes processing device in this embodiment is a multi-tub washing machine, including at least a first washing tub and a second washing tub, the washing, dehydration and draining processes of the first washing tub and the second washing tub are independent, and each passes through The drainage pipeline of the first washing tub and the drainage pipeline of the second washing tub perform drainage, and the drainage pipelines of the first washing tub and the second washing tub are respectively controlled by independent control devices to switch the on / off state of the respective drainage pipelines. In addition, the drainage pipelines of the first washing tub and the second washing tub are connected and connected to the same main drainage pipeline, and the washing water is discharged out of the machine body through the main drainage pipeline...

Embodiment 2

[0046] Such as Figure 4 and Figure 5 As shown, this embodiment is a further supplement to the fact that the washing tub in embodiment 1 performs a dehydration program. In this embodiment, when the first washing tub is dehydrating from a low-rotation speed to a high-rotation speed, the drainage pipeline of the second washing tub is closed. When the dehydration of the first washing tub is stable at a high-speed dehydration state, the drainage pipeline of the second washing tub can be opened. This is because when the clothes processing device is performing the dehydration program, the amount of drained water will increase significantly when the speed increases from low speed to high speed, and this is the most concentrated period of water discharge in the dehydration stage. Therefore, similar to Embodiment 1, in order to prevent the washing water from being poured back into the washing tub from the drain pipe, the drain pipes of each washing tub are also controlled similarly ...

Embodiment 3

[0050] Such as Figure 6 As shown, this embodiment discloses a multi-tubular laundry treatment device using the method for controlling the drainage of the laundry treatment device described in the above embodiments.

[0051] Such as Figure 6 As shown, the laundry treatment device includes a housing 9, in which at least a first washing tub 8 and a second washing tub 7 are disposed. As shown in the figure, the first washing tub 8 is located on the upper part of the second washing tub 7 , and the drainage height of the first washing tub 8 is higher than that of the second washing tub 7 .

[0052] The multi-tube laundry processing device in this embodiment is an upper drainage clothing processing device. The main drainage pipe 2 is provided with a drainage pump 4, and the drainage pump 4 is used to pump the washing water in the main drainage pipe 2 out of the body to complete the washing process. The drainage process of the treatment plant. The drainage pipeline 3 of the first...

Abstract

The invention discloses a drainage control method of a clothes processing device and the multi-tub clothes processing device. The clothes processing device at least comprises a first washing tub and asecond washing tub. A drainage pipeline of the first washing tub and a drainage pipeline of the second washing tub are communicated with each other and independently controlled to be opened or closed. When the first washing tub reaches the drainage process, whether the drainage pipeline of the second washing tub is opened or not is judged, if yes, the drainage pipeline of the first washing tub isnot opened until the drainage pipeline of the second washing tub is closed, otherwise the drainage pipeline of the first washing tub is opened. The problem is solved that when a multi-tub clothes processing device conducts drainage through a shared drainage pipeline, washing water in other washing tubs flow back into one washing tub, and clothes are contaminated, and especially the problem is avoided that vertical washing tubs conduct drainage or dewatering operation, and washing water in the upper washing tub is poured downwards into the lower washing tub.

Description

technical field [0001] The invention belongs to the field of washing machine equipment, and in particular relates to a method for controlling drainage of a laundry processing device and a multi-tube laundry processing device. Background technique [0002] At present, most drum washing machines on the market have only one washing drum. With the strengthening of people's hygiene awareness, more and more users need to wash different types of clothing separately or wash a small amount of clothing in time. With the improvement of people's quality of life, hygiene consciousness is also gradually improved, especially in household laundry washing, more and more people wash their clothes separately. If the existing washing machine is used for multiple times of washing, it is difficult to meet the requirements in terms of washing time; if two or more washing machines are purchased to wash separately and simultaneously, it will not only cause a great waste of energy and water resource...
