Problems solved by technology

[0005] In order to solve the problem of errors in the water intake or water replenishment of the multi-tubular washing machine in the prior art, the present invention proposes a multi-tubular washing machine, which is used to increase the water intake of the upper pulsator washing machine unit when the multi-tubular washing machine is dehydrating at a high speed in the lower drum washing unit. Or the accuracy of the water level when replenishing water, improving the user experience

Embodiment 1

[0022] When the set frequency difference between two adjacent gears is small (for example, 1000 Hz), the impact of the dehydration vibration of the lower drum washing unit 4 is basically the same as the set frequency difference corresponding to the two adjacent gears. Therefore, The target water level of the supplemented water is set to be one notch lower than the set notch.

[0023] figure 2 It shows a flow chart of the water replenishment mode of the multi-tub washing machine when the difference between the set frequencies corresponding to two adjacent gears is small.

[0024] The computer board 1 judges whether the upper pulsator washing unit 3 needs to replenish water. If it needs to replenish water, then judges whether the lower drum washing unit 4 is dehydrating at a high speed. , the upper pulsator washing unit 3 is normally replenished with water, that is, the water is replenished to the set gear Ls; if water replenishment is required and the lower drum washing unit ...

Embodiment 2

[0028] image 3 It shows a flow chart of the water supply mode of the multi-tub washing machine when the difference between the set frequencies corresponding to two adjacent gears is relatively large.

[0029] The computer board 1 judges whether the upper pulsator washing unit 3 needs to replenish water, and if it needs to replenish water, then judges whether the lower drum washing unit 4 is in high-speed dehydration. , the upper pulsator washing unit 3 is normally replenished with water, that is, the water is replenished to the set gear; if water replenishment is required and the lower drum washing unit 4 is also dehydrating at a high speed, the computer board 1 controls the target water level of the replenished water to be the set frequency and The water level corresponding to the sum of the frequency difference △f. Among them, the frequency difference Δf is the frequency detected by the computer board 1 when the lower drum washing unit 4 is dehydrating at the set gear and ...

Abstract

The invention discloses a multi-drum washing machine. The washing machine comprises at least one upper pulsator washing unit arranged side by side, lower drum washing units arranged at the lower parts of the upper pulsator washing units, a computer board used for executing the washing function of the multi-drum washing machine, and at least one water level detection unit used for detecting the water level frequencies of the upper pulsator washing units. When the computer board detects that the lower drum washing units execute dewatering and water needs to be supplemented into the upper drum washing units, the target water level of supplemented water is controlled to be lower than the set gear. The multi-drum washing machine is used for improving the accuracy of the water level in water feeding or supplementing of the upper pulsator washing machine units during high-speed dewatering of the lower drum washing units, and the use experience of a user is improved.

Description

technical field [0001] The invention relates to the technical field of multi-tubular washing machines, in particular to a multi-tubular washing machine. Background technique [0002] With the development of the economy and the improvement of people's living standards, the popularity of washing machines has gradually increased, and people's requirements for the performance of washing machines have become higher and higher. At the same time, more and more users need to wash the inner and outer clothes and children's clothes separately or to wash a small amount of clothes in time. Therefore, there have been multi-tub washing machines, especially three-tub washing machines, drum washing units and pulsator washing units. The body is arranged up and down, with two pulsator washing units arranged side by side at the top, and a larger drum washing unit at the bottom, and the pulsator washing unit and the drum washing unit are mechanically connected together. [0003] The water leve...
