Description
Technical Field
The utility model relates to a washing machine technical field particularly, relates to a washing machine degassing unit and washing machine thereof.
Background
When the washing machine washes clothes, the outer sleeve is sleeved outside the washing cylinder, washing water enters and exits from the middle of the two layers, the water is discharged from the interlayer, and dirt in the interlayer is very serious.
The interlayer of the washing machine is actually like a sewer, dirt of the interlayer mainly comprises water scale, washing agent freeness, fibers, organic substances, dust, bacteria, fungi and other garbage, and the impurities are firmly attached to the interlayer of the washing machine, propagate and ferment at normal temperature, pollute clothes during washing and bring to human bodies, and even cause itch and allergy of human skin.
The traditional washing machine disinfection methods are roughly as follows:
1. directly disassembling washing machine for cleaning and sterilizing
The method is thorough in cleaning and disinfection, but needs professional personnel to operate, and is complex in operation flow, time-consuming and high in charging.
2. Sterilizing disinfectant for washing machine
According to the practical application situation, the decontamination and deodorization effects of the washing machine sterilization disinfectant are not obvious, and residual disinfectant can damage clothes, the steps of soaking, washing and cleaning fragments in a barrel need to be carried out in the using process, the process is slightly complicated, and a plurality of users often do not use the washing machine after trying to use the washing machine for a plurality of times, so that high-end washing machine brands often carry sterilization and disinfection equipment by themselves and do not rely on the washing machine sterilization disinfectant.
3. Ozone generator for washing machine
Some washing machines have an ozone generator mounted at the bottom to produce ozone for sterilizing the clothes and the interior of the washing machine. However, the strong oxidizing property of ozone determines that ozone is corrosive, and when ozone is used for sterilization and disinfection, the concentration needs to reach a certain height, so that green rusty spots can appear on copper sheets, common rubber is aged, discolored and reduced in elasticity, so that the common rubber becomes brittle and broken, fabrics are bleached and discolored, and the like.
4. Using silver ion generators
Some washing machines are designed with silver ion generators. When the washing machine works, pure silver in the silver ion generator is electrified to electrolyze silver ions, and the silver ions enter the washing bucket along with washing. During the washing process, silver ions penetrate through the fabric of the clothes to deeply penetrate and sterilize the clothes, and a protective film is formed on the clothes and the inner drum, so that the breeding of bacteria can be continuously inhibited, and the aim of disinfecting the inner drum of the washing machine is fulfilled. However, the silver ion electrolysis of pure silver is a process of continuously consuming silver, which is costly, and the silver ion belongs to heavy metal ion, and it flows into the nature along with the discharge of the laundry wastewater, and it will pollute the water and soil.
5. Using high temperature sterilization
High-temperature sterilization is a widely and easily practiced sterilization method in which proteins and enzymes of microorganisms are coagulated or denatured by high temperature to be killed. At present, some washing machines have a high-temperature washing mode, and most of germs can be effectively killed. Boiling in water to 100 ℃, and then continuing for 15-20 minutes. The method can kill common bacteria, and can effectively sterilize bacteria with spores only after 3 days, wherein the bacteria with spores need to be boiled for at least 1-2 hours every day; the disadvantages of high-temperature sterilization are easy aging of plastic parts of the washing machine, large energy consumption and large water consumption.
