Description

Washing machine drainage, washing machine and control method

The present invention relates to a washing machine field, and more particularly, to a washing machine drainage device, a washing machine, and a control method.

The washing machine performs washing, rinsing, drying and dehydrating courses, and uses the interaction of the detergent and water to wash the marks conveniently when attached to the laundry. Dryer is another typical laundry processing device, which is used to dry wet laundry. Recently, home appliances that combine the functions of a washing machine and a dryer have already been widely used. Inside a conventional washing machine, external cylinders are in an enclosed environment and only water can pass through them. Due to the limitations of the structure of the washing machine and the specificity of the environment of use, when used for 3 to 5 months, there is a time lag between the outer wall of the inner cylinder and the inner wall of the inner cylinder, and the bacteria are proliferated with varying degrees of difference. .

As the standard of living of people has increased, the demand for quality of life has increased, and the hygiene problem of the washing machine has become a problem that can not be neglected already. As a result of research on the internal environment of the washing machine, more and more consumers are already paying attention to the seriousness of the contamination inside the washing machine. In order to prevent secondary contamination of laundry in the washing machine and to protect the health of the user, the problem of cleaning the internal environment of the washing machine is an urgent problem to be solved.

Chinese patent 200820183308.4 discloses a set washer washing machine which cleans the washing tub, which includes an inner cylinder, an outer cylinder, and several silica gel balls for cleaning the inner and outer cylinders. This washing machine uses the rotation of the water due to the rotation of the inner cylinder to wash the inner and outer cylinders of the washer so that the silica gel ball between the inner cylinder and the outer cylinder of the washer collides with the inner wall of both the inner cylinder and the outer cylinder, To achieve the goal.

In addition, Chinese patent 201010160548.4, which was previously filed by the applicant, discloses a washing machine and method for cleaning the inside of the washing machine and the outside cylinder with the flexible particles. The washing machine cleans the inner cylinder of the inner cylinder of the washing machine and the inner cylinder of the outer cylinder by using the impact and friction of the particles due to the regular flow of water in the process of washing the laundry by arranging the flexible particles between the inner and outer cylinders of the washing machine. However, the structure of the washing machine described above is structurally disadvantageous in that the silica gel or the flexible particles are dispersed naturally in the cylinder after draining, thereby causing a great noise in the high-speed dehydration process and consuming the energy of the washing machine. . In this way, the structure of the existing drainage device is improved, but the filtration structure for collecting the cleaning particles is installed to filter and discharge the residue to prevent clogging. In addition, the cleaning particles can be automatically injected during the next washing, It is a priority to provide a drainage device that can disassemble and replace cleaning particles.

In the Chinese patent 201210189764.0 previously filed by the applicant, a kind of washing machine drainage device is disclosed. The washing machine includes an outer cylinder, an inner cylinder and a rotating blade, and a cleaning particle for cleaning the inner wall is installed between the inner and outer cylinders. As shown in FIG. 1, the drainage unit accommodates the cleaning particles when dewatering. When the water is drained, the cleaning particles are moved to the outer cylinder by buoyancy, and the particle storage chamber 1 ' Clean the steel chamber 2 '. The particle storage chamber 1 'and the drain port are communicated by the communication pipe 3', and the particle storage steel chamber 1 has an inclined inner wall structure. As the water level of the cleaning particles 4 'increases, It then flows into the communication pipe and flows through the drain to the external cylinder.

However, as a result of extensive experimentation, the structure described above still has the following problems. 1. Most of the cleaning particles are attached to the inner wall of the slope so that they can not immediately flow from the water inlet to the outer cylinder due to buoyancy in the water supply process of the washing machine and are not floated upstairs for a long time. Particles, especially if they stay in the storage room for too long, will be stuck on the bottom of the storage room by being pushed to the left and right. 2. When the washing machine is drained, due to the influence of the cleaning particles, the debris is concentrated on the front surface of the filtration structure and can not be discharged. If accumulated for a long period of time, it will affect the drainage efficiency and also the cleaning particles will be tangled. .

Further, the inside diameter gradually decreases according to the drain / exhaust direction. The structure increases the water supply / supply air pressure and mixes the cleaning particles inside the particle storage chamber using a relatively large water / air impact force.

The present invention provides another washing machine drainage device, which includes a drain valve body, a water supply port and a drain port, a particle storage chamber communicating with a water supply port is provided in the drain valve body, a particle filtration structure is provided between the particle storage chamber and the drain port , And the drainage apparatus is provided with an air pump unit for supplying water to the particle storing steel chamber.

In the present invention, water is supplied to a particle storing steel chamber by a pump unit, and an impact is applied to a cleaning particle in a particle storage chamber to cause irregular movement so that clogged or entangled thread residue particles are scattered and a new drain interval is formed again Allows waste to be discharged smoothly.

The washing machine described in the present invention is provided with cleaning particles for cleaning the inner wall between the inner cylinder and the outer cylinder, between the inner cylinder and the outer cylinder. The drain port of the outer cylinder communicates with the drainage device at the lower side. The drainage device collects the cleaning particles into the particle storage chamber at the time of drainage and floats between the inside of the washing machine and the outer cylinder at the water supply port due to the buoyancy of water at the time of water supply.

In the laundry washing process of the present invention, cleaning particles inside and outside the cylinder wall are realized by impacting and rubbing the cleaning particles on the inner and outer cylinders by using water bodies. After the cleaning, the washing water is discharged from the drainage device, and the cleaning particles are collected into the particle storage chamber.
