The invention relates to a dehydration method and a device for preventing deformation of clothes during energy saving, in particular to an assembly of a torque estimator and a controller without changing the existing structure of the dehydrator, thereby achieving protection against deformation and energy saving of the clothes. Method and equipment for dehydration efficiency.

According to the development of technology, the development of a variety of electrical products that facilitate people's lives, such as washing machines and dehydrators, can save a lot of effort and time for busy modern people to deal with dirty clothes; however, today's washing machines and dehydrators When the clothes are dehydrated, the centrifugal force is applied to drive the washing tank or the dewatering tank to rotate, and the water contained in the clothes is dried. When the water content of the clothes is large, if the water is dehydrated by a large rotation speed, the powerful one is strong. Centrifugal force easily causes the clothes to be pulled and deformed. In addition, the existing washing machine and the dewatering machine mainly set the dehydration time by the user. However, the actual dehydration time varies with the quantity of the clothes and the material of the clothes, and the dehydration time must be regulated according to the user's rule of thumb, often resulting in The user sets the dehydration time for a long time or does not dry out a single time and must repeat the dehydration process repeatedly.

Therefore, the inventor of the present invention proposed the invention and the new patent case of "Energy-saving time-saving dehydration device for preventing deformation of clothes against torque control" in the case No. 103125998 of China and No. 103213498 of China, which mainly used the dehydration barrel inside. One end of the flexible body of the barrel and a torque sensor is assembled with the second coupling, and the other end of the flexible body is combined with a rotating power source by the first coupling, and the first The first coupling and the second optical sensor are respectively disposed at the second coupling, and the first and second optical sensors are coupled to the clock detector, and the clock detector and the rotating power are further enabled. The source is coupled to the controller, so that when the rotary power source drives the inner tub to rotate through the torque sensor to dehydrate the laundry in the inner tub, the torque sensor is used to feedback the torque to estimate the clothes to dry. The degree is automatically adjusted, and the operation is stopped in time to achieve energy saving and time-saving dehydration. However, the invention and the new patent case of "China's case number 103125998" and China's case No. 103213498 "energy-proof dehydration device for preventing deformation of clothes by torque control" are required to be between the inner barrel and the rotary power source of the dewatering barrel. Assembling the flexible body, the first coupling, the second coupling, the first light sensor, the second light sensor, the pulse detector, and the like, which causes the assembly to be time-consuming and inconvenient to assemble. .
