Embodiment 1

[0047] This embodiment proposes a washing machine, including a washing tub. The washing tub includes an inner tub and an outer tub. The washing machine is provided with a circulation pipeline communicating with the outer tub, and the water in the outer tub can be circulated through the circulation pipeline. A water pump, a filter device and a bubble generating device are installed on the circulation pipeline, and the water pump generates water circulation flow force; the filter device is used to filter out impurities and dirt in the water to improve washing efficiency; the bubble generator is used to generate bubbles into the water to form bubble water , can improve the dissolution efficiency of detergent, reduce the use of detergent, improve washing efficiency and rinsing efficiency, and achieve the effects of sterilization, environmental protection and water saving. Wherein, the washing tub may be a washing tub of a drum washing machine, and in this case, the washing machine ...

Embodiment 2

[0092] The difference between the present embodiment and the first embodiment is that the present embodiment separately sets the filtering device flushing pipeline 9 to improve the flushing effect on the filtering device.

[0093] Such as Figure 6-8 As shown, the circulation pipeline 4 between the filter device 6 and the air bubble generator 7 is connected with a filter device flushing pipeline 9, and the flushing pipeline 9 can be connected to the water inlet pipe, and the flushing pipeline 9 and the drain pipe 3 are connected , the water in the flushing pipeline 9 is discharged through the drain pipe 3 after flushing the filter device 6 . Therefore, in this embodiment, compared with the first embodiment, the flushing pipeline 9 is directly connected to the water inlet pipe, and the flushing time or the amount of flushing water can be set according to requirements, which can improve the flushing effect.

[0094] Such as Figure 9 As shown, the controller of the washing mac...

Embodiment 3

[0129] Since there is also a small amount of impurity and dirt in the water in the circulation pipeline, in order to avoid the undesirable effect that the water in the circulation pipeline cannot be rinsed off when the filter device is flushed. Such as Figure 11 As shown, the difference between the present embodiment and the second embodiment is that a third switch 10 is provided on the circulation pipeline between the filter device and the bubble generating device, and the third switch 10 is located at the same position as the bubble generating device and the flushing pipeline and the circulation pipeline. between connected positions.

[0130] The controller controls the state of the third switch. The controller controls the state of the air bubbles or the flushing state by controlling the states of the first switch, the second switch and the third switch.

[0131] Such as Figure 12 As shown, the controller of the washing machine outputs control signals to the water pump...

Abstract

The invention discloses a washing machine and a control method thereof. A water pump, a filtering device and a bubble generating device are arranged on a circulating pipeline, communicating with an outer barrel, of the washing machine, wherein the filtering device and the bubble generating device are sequentially arranged in the water flow direction of the circulating pipeline. The bubble generating device can improve the dissolving efficiency of a detergent and reduce the use of the detergent, can achieve the effects of sterilization, environmental protection and water saving, and has the cleaning effect on an inner barrel and the outer barrel, thereby reducing secondary pollution. When the water pump works, washing water in the washing machine firstly passes through the filtering deviceto filter out impurities and dirt and then passes through the bubble generating device to generate bubbles, and the filtering device can generate the protective effect on the bubble generating device,so that the service life of the bubble generating device is prolonged and the secondary pollution caused by the fact that the impurities and the dirt enter the washing barrel is prevented. Accordingto the washing machine, the effects of filtering the impurities and the dirt and generating the bubbles can be synchronously realized in the same circulating pipeline, the structure is simplified, thewashing efficiency and the rinsing efficiency are greatly improved, and water resources are saved.

Description

technical field [0001] The invention belongs to the technical field of laundry equipment, and in particular relates to a washing machine and a control method thereof. Background technique [0002] At present, washing machines need to add detergent, softener, disinfectant and other cleaning products to wash clothes. After rinsing, there are often residues of the above cleaning products, which will not only cause adverse effects such as fading or damage to the clothes, but also affect human health. The skin can also produce allergies, inflammation and other damage. Especially the clothes of infants and young children, because the skins of infants and young children are immature, they are more likely to be allergic and inflamed to the remaining washing products on the clothes. Now generally by increasing the number of times of rinsing to reduce the residual situation of washing articles, however, increasing the number of times of rinsing has the problem of wasting water resour...
