Description

Clothes processing device and washing method

technical field

The invention belongs to the field of cleaning equipment, and in particular relates to a clothes treatment device.

Background technique

There are generally two ways to put washing powder into the laundry treatment device in the prior art: one way is to pour it directly on the clothes in the laundry treatment device. This kind of washing powder feeding method makes the washing powder fill in the gaps of the clothes. After the clothes are washed, the clothes are folded and entangled due to the impact of rotation and water flow. The washing powder is buried in the clothes and cannot fully contact with the washing water. Poor dissolution of the washing powder; another way is to place the washing powder in the washing powder box, directly connect the water inlet of the clothes treatment device with the washing powder, and the washing powder is directly washed down by tap water in the washing powder box, Under the impact of gravity and water flow, the washing powder will settle to the bottom of the inner tub, so that the washing powder is blocked by the clothes and cannot fully contact with the washing water, resulting in a small amount of washing powder dissolved in the washing water in the washing tub, so the washing powder in the washing tub Low concentration will lead to poor washing effect and easy to cause waste of washing powder. Moreover, the undissolved wet laundry powder will adhere to the clothes, and even after repeated washing operations, the local laundry powder residues on the clothes are still obvious. Further, the residual washing powder will be further brought into the rinsing process, causing the clothes to be unclean. Clothes eroded by washing powder will turn yellow and change color after drying.

Clothes treatment devices are cleaning appliances that use electrical energy to generate mechanical action to wash clothes. With the improvement of people's quality of life, the popularity of clothes treatment devices is getting higher and higher, and the requirements for the functions and performance of clothes treatment devices are becoming more and more detailed. In order to better achieve the stain removal effect, it is very important to maximize the activity of the laundry detergent while improving the laundry function of the laundry treatment device. Moreover, with the development of clothes treatment device technology, the clothes treatment device develops towards the direction of multi-function and multi-component integration, so that the types of functional components of the clothes treatment device continue to increase, resulting in a more compact and multi-functional structure design of the clothes treatment device. development in the direction of integration. It makes it difficult to coordinate the design of movable parts such as the washing powder box with other parts, and in order to improve the utilization rate of the control panel of the multi-functional clothes processing device, there is nowhere to place such a large space-consuming part as the washing powder box.

In view of this, the present invention is proposed.
