As shown in Figures 1 to 7, the present invention discloses a method for controlling drainage of a laundry treatment device and a multi-tubular laundry treatment device. The laundry treatment device includes at least a first washing tub 8 and a second washing tub 7. The drainage pipelines of the cylinder 8 and the second washing cylinder 7 are connected, and the opening and closing of the drainage pipelines are controlled independently; Open the first washing tub drainage pipeline 3 after closing the second washing tub drainage pipeline 5; otherwise, open the first washing tub drainage pipeline 3. The invention solves the problem that the washing water in other washing tubs flows back into the washing tubs when the multi-tubular laundry processing device uses the shared main drainage pipeline 2 to drain water, thereby causing the clothes to be polluted, especially avoiding the washing water that is arranged up and down. When the drum is draining or dehydrating, the washing water in the upper washing drum is poured back into the lower washing drum.

Example 1

As shown in FIG. 1 to FIG. 3 , 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. The drainage device in this embodiment is a drainage valve arranged on the respective drainage pipelines of different washing tubs for controlling its on-off.

When the drainage pipeline of the second washing tub is opened, the second washing tub is in communication with the main drainage pipeline. At this time, if the washing water in the main drainage pipeline cannot be discharged for some reason, when the washing water liquid level in the main drainage pipeline rises to a height higher than that of the control device of the second washing tub, it is very easy to The washing water is caused to flow backward from the main drainage pipeline along the drainage pipeline of the second washing tub, such as in the second washing tub. The situation that causes pollution or water leakage in the second washing tub occurs.

Therefore, as shown in Figure 1, in this embodiment, when the first washing tub reaches the drainage process, it is judged whether the drainage pipeline of the second washing tub is open, and if so, wait for the drainage pipeline of the second washing tub to be closed before opening Drain line of the first washing tub; otherwise, open the drain line of the first washing tub. That is to say, in order to prevent the washing water in the first washing tub from being poured into the second washing tub, if the drainage pipeline of the second washing tub is in an open state, the drainage pipeline of the second washing tub must be closed first before the first washing can be performed. Drain operation of washing drum. This ensures that when the first washing tub is performing the drainage process, the drainage pipeline of the second washing tub and the main drainage pipeline are in a cut-off state, which eliminates the need for washing water to flow into the second washing tub from the main drainage pipeline. Drain line risk.

Further, as shown in FIG. 2, when the first washing tub reaches the drainage process, if the drainage pipeline of the second washing tub is opened and the drainage process is in progress, the first washing tub waits for the second washing tub to be emptied and Close the drain line of the second washing tub and then open the drain line of the first washing tub. Such setting gives priority to ensuring the smooth completion of the drainage process of the second washing tub. Under the overall design idea of the present invention, the number of opening and closing of the drain valve of the second washing tub is further reduced, and the use of the drain valve of the second washing tub is extended. life. In this case, after the washing water in the first washing tub is emptied, the drainage pipeline of the second washing tub can be opened again.

Further, in the multi-tube laundry processing device with the washing tubs arranged up and down, the drainage height of the first washing tub is higher than that of the second washing tub. In this setting of the present invention, the second washing tub reaches the drainage process , further judgment is required. As shown in Figure 3, when the second washing tub reaches the drainage process, it is judged whether the drainage of the first washing tub is in progress. Drain line for second wash tub. In this drainage process, the second washing tub waits for the first washing tub to be emptied before draining. Since the drainage height of the first washing tub is relatively high, when the first washing tub is empty, as long as the second washing tub If the washing water in the tub can be discharged smoothly, the backflow of washing water will not occur, and there is no need to close the drain valve of the first washing tub again. In such a control process, the number of opening and closing times of the drain valve of the first washing tub is reduced, and the service life of the drain valve of the first washing tub is prolonged.

Example 2

As shown in FIG. 4 and FIG. 5 , 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 to Embodiment 1.

As shown in Figure 4, before the speed-up switch from low-speed dehydration to high-speed dehydration in the first washing tub, it is judged whether the drainage pipeline of the second washing tub is closed. Dehydration transition, and finally high-speed dehydration; otherwise, the first washing drum maintains a low-speed dehydration state. That is to say, in order to prevent the washing water from being poured into the second washing tub during the switching process from the low-speed dehydration stage to the high-speed dehydration stage in the dehydration state in the first washing tub, if the drainage pipeline of the second washing tub is in an open state, Then the drainage pipeline of the second washing tub must be closed first to perform the dehydration and speed-up drainage operation of the first washing tub; This also ensures that when the drainage volume of the first washing tub increases during the dehydration speed-up process, the drainage pipeline of the second washing tub and the main drainage pipeline are in a cut-off state, which eliminates the flow of washing water from the main drainage pipeline. Risk of flow into the second wash tub drain line.

Further, as shown in Figure 5, if the first washing tub is switched from low-speed dehydration to high-speed dehydration, if the drainage pipeline of the second washing tub is opened and the drainage process is in progress, wait for the first washing tub After the second washing tub is emptied and the drainage pipeline of the second washing tub is closed, the first washing tub will change from low-speed dehydration to high-speed dehydration, and finally achieve high-speed dehydration. This setting firstly ensures the drainage of the second washing tub The smooth completion of the process, under the overall design idea of the present invention, further reduces the number of opening and closing of the drain valve of the second washing tub, prolonging the service life of the drain valve of the second washing tub. In this case, when the first washing tub stabilizes at a high-speed dehydration state, the drain pipeline of the second washing tub can be opened again.

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 washing tub and the drainage pipeline 5 of the second washing tub are respectively controlled by independent control devices to switch the on/off state of the respective drainage pipelines. As shown in the figure, the control device is a drain valve, and the drainage pipeline 3 of the first washing tub and the drainage pipeline 5 of the second washing tub pass through the first washing tub drainage valve 1 arranged on the respective drainage pipelines. and the second washing tub drain valve 6 to control the on-off of the respective drain pipelines respectively. The first washing tub drainage pipeline 3 and the second washing tub drainage pipeline 5 are connected to the same main drainage pipe 2, and the washing water is discharged from the body through the main drainage pipe 2.

The multi-tube laundry processing device in this embodiment adopts the drainage and/or dehydration control method of the above-mentioned embodiment, and only needs to use a drainage pump to realize that there will be no washing water in different washing tubs during the independent drainage process. Backfilling problem. There is no need to additionally add other drain pumps or carry out the transformation of the water, which reduces the installation cost of the multi-tube laundry treatment device.

Example 4

As shown in FIG. 7 , it is a supplement to the multi-tube laundry processing device of Embodiment 3. The difference between this implementation and Embodiment 3 is that the clothes treatment device in this embodiment is for drainage, no drainage pump is installed, and the first washing tub drainage pipeline 3 and the second washing tub drainage pipeline 5 are connected to the same main drainage Pipe 2, and through this main drain pipe 2, the washing water is discharged from the body. The first washing tub 8 and the second washing tub 7 arranged up and down.
