Description

A closed air washing machine

technical field

The invention belongs to the technical field of washing machines, in particular to a closed air washing machine.

Background technique

With the progress of society, people's living standards are gradually improving, and the pace is also accelerating. At the same time, the awareness of environmental protection is also increasing. For washing clothes, it is required to be environmentally friendly and fast. Therefore, people continue to improve or update washing machines. In recent years, vertical washing machines and drum washing machines have been introduced; in terms of detergents, because detergents pollute the environment more or less and stimulate people's skin, people are trying their best to find washing machines without detergents. It is well known that ozone has poor stability at normal temperature and pressure, and can be decomposed into oxygen by itself; ozone has the smell of grass, and inhaling a small amount is beneficial to the human body, and the bactericidal ability of ozone is not affected by changes in pH value and ammonia. Chlorine is 600-3000 times larger, and its sterilization and disinfection effects are almost instantaneous. When the ozone concentration in water is 0.3-2 mg/L, bacteria can be killed within 0.5-1min. However, to achieve the same sterilization effect (such as killing E. coli at a rate of 99%), the dosage of ozone water is only 0.0048% of that of chlorine. As long as the concentration of ozone that people are exposed to is not greater than 0.2mg/m³, it is safe. Ozone has been used in the world for more than 100 years, and there has not been a single case of death caused by ozone poisoning. Therefore, ozone is an extremely environmentally friendly cleaning and sterilizing substance. Since the 1990s, some people have proposed to use ozone to wash clothes, and use the vibration and bursting impact of ozone bubbles in water to clean and sterilize clothes. The applicant's application number is 201510211504.2. Use high-pressure air flow combined with water flow to quickly strip the stains on clothes, and use ozone to sterilize and decontaminate. It has the characteristics of no detergent, short washing time, clean clothes, no wear on clothes, and no pollution to the environment. After continuing research and experiments, the applicant found that because the equipment is an open laundry machine, the ozone is easily discharged, resulting in poor sterilization and disinfection effects. Due to the large number of spiral air nozzles at the bottom, the air supply of the air compressor is insufficient, and the pressure of the high-pressure gas is biased. Low, the washing effect on some stubborn stains on the clothes is poor, and the energy consumption is large.

Beneficial effects of the present invention:

1. The washing process of the washing machine in the present invention is carried out in a closed system. The ozone generator generates ozone, and through the action of the air compressor and electric heater, the water and clothes can be sterilized and disinfected throughout the whole process, and the utilization rate of ozone is higher. The energy consumption is lower. In addition, the inner diameter of the exhaust pipe is larger than the inner diameter of the spiral air nozzle, so that the closed system always maintains a certain negative pressure, which is conducive to the bursting of high-temperature and high-pressure air bubbles, and increases the impact force, and the washing effect is better. After washing, it is electronically controlled. The controller controls the second electronic one-way valve to open to discharge the water through the drain spout.

2. In the present invention, since the closed system is used for washing, the motor does not need to drive the laundry tub to rotate to form centrifugal force dehydration when dehydrating the clothes, but realizes that the high-pressure gas squeezes and removes the water in the clothes in the closed cavity, greatly reducing The complexity of the mechanical structure of the washing machine is reduced, and the processing cost is reduced. At the same time, the stability and reliability are significantly enhanced, the mute effect is better, and the dehydration effect is better.

3. In the present invention, a damping net cover is set in the washing bucket. The special structure of the damping net cover can be fixed at any height in the washing bucket, and the washed clothes can be pressed in a small space in the washing bucket to increase the high pressure. The action time of gas and clothes, the structure of the damping net makes the blasting rate of high-pressure air bubbles higher and more powerful, and improves the effect of stain removal. The size of the screen on the damping net expands from the center to the surrounding distribution, which is conducive to the uniform impact and blasting of high-pressure air, improving Uniform washing effect of clothes, improve washing efficiency.

4. Compared with the original equipment, the present invention only installs a spiral atomizing nozzle in the center of the washing bucket. After cooperating with the damping net cover, it not only improves the bubble burst rate of high-pressure gas, but also ensures the high-pressure pressure of high-pressure gas, and reduces the air pollution at the same time. Compressor power consumption.

5. Compared with the original equipment, the present invention uses the calorific value of the air compressor to heat to form hot water and high-temperature ozone to wash the clothes with hot water and hot air, which greatly improves the removal rate of stains and improves the operation of the air compressor. At the same time, the heat utilization rate is higher, the energy consumption is lower, and the decontamination effect is stronger.
