What are the new technologies applied in washing machines?
Traditional washing machines only have washing and dehydration functions. With the continuous development of new washing machine technologies, the functions of washing machines are increasing. Washing machines have evolved from simply being able to wash clothes to having high cleanliness, low wear, health, intelligence, water saving, electricity saving and other advanced functions. There are mainly 8 new technologies applied in washing machines:
1. Improvement of manufacturing materials
(1) Stainless steel inner drum: After using the fully automatic agitator washing machine for a period of time, some dirt will accumulate on the back of the plastic inner drum, causing bacteria breeding, which pollutes the washed clothes and endangers human health. The new type of washing machine all uses stainless steel as the inner drum, which is not only anti-mildew and anti-corrosion, but also beautiful and durable.
(2) Antibacterial agitator: When washing, some dirt will accumulate at the bottom of the agitator, thus breeding bacteria. In the injection molding process of the agitator of the new type of washing machine, some trace elements with antibacterial effects are added to its base material, which can effectively inhibit the generation of mold on the surface of the agitator.
2. High-efficiency permanent magnet DC motor
The Ronshen XQJ52-600PET bionic kneading stirring washing machine adopts a high-efficiency permanent magnet DC motor. Both the rotor and stator of this motor are injection-molded with PET material, and its armature winding is wound on the stator core covered with plastic. It can not only meet the requirements of mechanical strength, but also has the advantages of low operation noise and energy saving.
3. Magnetization technology
Magnetization technology uses magnetic field to destroy the association state of laundry water, making the associated water molecules smaller, thereby stimulating the activity of water, facilitating the exertion of detergent, and improving the stain removal ability.
4. Ozone technology
Ozone technology is to set an ozone generator at the bottom of the washing machine. During the operation of the washing machine, the ozone generator continuously injects ozone gas into the washing water, turning the washing water into a certain concentration of ozonated compound, which plays a sterilizing role.
5. Fuzzy control technology
Fuzzy control technology is to set up a computer and various precise intelligent sensors in the washing machine. It can automatically detect and judge the weight, fabric quality, and dirt level of the laundry. It reasonably sets the water level, temperature, time and other washing programs, so that the washing machine achieves the best washing effect.
6. Variable frequency speed regulation technology
Variable frequency speed regulation technology changes the speed of the motor by changing the power supply frequency. Through variable frequency speed regulation, the following effects can be achieved:
1) Realize multiple water flows under different speeds through variable frequency speed regulation to meet the high-level laundry requirements.
2) Achieve soft start of the washing machine through variable frequency speed regulation. The motor speed can gradually increase from zero to the highest speed, making the dehydration bucket run smoothly and reducing running noise.
3) Improve the dehydration operation speed through variable frequency speed regulation. The dehydration operation speed of the drum washing machine can be increased from 800r/min to 1200r/min, which can not only shorten the laundry time, but also improve the dehydration rate.
7. Nanotechnology
Nanotechnology adds nano-materials with antibacterial and bactericidal functions to the inner and outer drum manufacturing materials of the washing machine. Some also coat nano-materials on the surface of the inner and outer drums, so that bacteria cannot survive on the drum wall, thereby achieving the purpose of sterilization and antibacterial.
8. Silent balance technology
Noise is an important indicator of washing machines. Silent balance technology mainly reduces noise from the following three aspects:
1) Configure a plastic balance ring with salt water encapsulated in the cavity at the rotating part of the washing machine. The axis line of the balance ring coincides with the axis line of the washing bucket. When the washing bucket rotates, the inertia of the liquid salt water buffers the inertia of the rotating bucket, thereby adjusting the deflection amount of the washing bucket and reducing the operating noise of the washing machine.
2) Change the transmission mode of the motor, that is, change from indirect (belt) transmission to direct (the motor shaft is directly connected to the rotating part) transmission, greatly reducing the noise of the washing machine.
3) Change from AC motor to DC motor, completely eliminating the AC noise generated by the AC motor, greatly reducing the operating noise of the whole machine.
