Background technique

Types of washing machines include pulsator washing machines, drum washing machines, agitating washing machines, jet washing machines, etc.

1. The power of the pulsator washing machine is generally about 400 watts, and the power consumption is less than 0.5 kWh. The washing power of the drum washing machine is generally about 1200-2500 watts. In addition, the electric heater needs to increase the water temperature to achieve a better washing effect when washing the drum washing machine. If the water temperature is increased to 60 degrees Celsius, the power consumption is about 1.5 degrees.

2. The drum-type washing machine adopts water-saving technology to control the amount of water, heating washing technology, rain, soaking, beating triple washing, three-dimensional water flow and other modes and waterproof overflow function, the role of water is played to the extreme.

3. The agitating washing machine has the strongest cleaning power and saves washing powder. Disadvantages: It is more damaging than the previous two methods, and the noise is the largest.

4. The jet washing machine has a short washing time, easy to wash off the dirt, simple machine structure, and fewer failures. However, due to the fierce water flow, the clothes are easily twisted together, so the washing is uneven and the clothes are severely damaged, and the washing liquid is easy to splash during washing.

However, the above-mentioned existing washing machines have the following substantial problems:

1. Existing washing machines still have light stains on heavily soiled clothes even after washing, which cannot achieve the effect of manual scrubbing.

2. When washing the existing drum washing machine, the laundry is thrown by the drum to a high place and then dropped back to a low place to circulate the laundry, but this movement mode does not make the clothes evenly scrubbed with force, and the cleaning effect is limited.

3. Existing washing machines cannot fully wash the washing powder under the condition of limited water changes, resulting in some residual washing powder on clothes.

4. After the washing machine has been used for a period of time, the exterior looks as bright as new, but the space between the outer wall of the inner tube and the inner wall of the outer tube contains dirt and contains harmful bacteria. If the dirt is not removed in time, it will cause damage. Human health causes harm.

5. When the inner cylinder and the outer cylinder in the prior art are disassembled, the inner cylinder needs to be positioned when it is restored to ensure the installation is in place. However, in the prior art, the installation and alignment is a cumbersome task, and it is not easy to align and install at one time. It is in place and needs to be tried repeatedly.
