Energy-saving time-saving dewatering device for preventing deformation of clothes by torque control

The invention relates to an energy-saving time-saving dehydration device for preventing deformation of clothes against torque, in particular to a torque sensor connected between a dewatering bucket and a rotary power source, and using the torque sensor of the torque sensor to control The device can estimate the degree of de-drying of the clothes, and automatically adjusts the rotation speed, and automatically stops the operation of the dehydration device with energy saving and time-saving benefits when the machine is dried.

According to the development of a variety of electrical products that facilitate people's lives, modern people only need to touch the control button to drive the washing machine and dehydrator for sputum, rinse and dehydration. The laundry action saves the traditional strength and time of hand laundry.

The use of washing machines and dewatering machines, such as washing and dewatering, can save busy modern people a lot of effort and time to deal with dirty clothes. However, when the existing washing machine and dehydrator are dehydrated, the centrifugal force is mainly used to drive the laundry by the motor. The tank or the dewatering tank rotates, and the moisture of the clothes placed therein is dried, and the motor is dehydrated at the same rotation speed from the start of dehydration to the end, so that not only the pulling deformation of the clothes is easily caused, but also the improper loss of electric energy is caused.

Furthermore, the existing washing machine and the dewatering machine mainly set the dehydration time by the user. However, the actual dehydration time of the clothes changes with the quantity of the clothes and the material of the clothes, so the implementation must be regulated according to the user's rules of thumb. Dehydration time, here, for users who are unfamiliar with the material and quantity of clothing, it is often necessary to set a long dehydration time, or the set dehydration time is too short, and the clothes are not dried. Repeated dehydration, in addition to causing improper dehydration time, it will further cause excessive deformation of clothing and improper loss of electrical energy, etc., which does not meet the environmental protection needs of modern people for efficiency and energy saving.

The reason is that the present inventors have in view of the fact that the dewatering device such as the washing machine and the dehydrator is easily used to cause deformation of the clothes and improper loss of electric energy, etc., and is supported by many years of manufacturing and design experience and knowledge in related fields, and is multi-party.
