The invention discloses a belt switch structure of a dryer, and a working method thereof; the belt switch structure comprises a motor, a belt, a base of a fixed motor and a tension device of a tension belt; the tension device consists of a tension arm used to support the belt and a tension spring used to regulate the tensioning degree; one end of the tension arm is pivoted and fixed on the base; the arm body supports the belt, and the other end regulates the tensioning degree by the fixation of the tension spring; the structure is characterized in that the belt switch structure also comprisesa micro switch and a bend arm used to trigger the micro switch; the bend arm is arranged on the fixed end of a tension arm pivot shaft; the bend arm is arranged on the outer side of the tension arm; the micro switch is fixed in an area on the base which the bend arm can trigger when rotating; the triggering area is an area rotated by the bend arm when the belt is broken, the spring is tightened to pull the tension arm to rotate. The structure has simple structure, is convenient to be installed, has low production cost and good effect, is simple to be used, and can greatly reduce the loss brought by the breakage of the belt.
Description
technical field [0001] The invention relates to a clothes dryer, in particular to a belt switch structure of the clothes dryer, and in particular to a working method of the belt switch structure. Background technique [0002] Generally, the clothes dryer is installed independently of the washing machine so as to automatically dry the wet laundry having completed the washing operation. According to the drying method, clothes dryers can be divided into condensation type and exhaust type. [0003] The exhaust type clothes dryer sucks outside air, heats the sucked air with a heater and then introduces it into a drum, and exhausts the air passing through the drum, thereby drying laundry in the drum. [0004] Such as figure 1 As shown, a conventional exhaust type clothes dryer includes: a housing 10 , a drum 12 , an air circulation device 15 , a heater 16 and a drum rotating device 14 . Housing 10 has the inlet 10a that is used to put into clothing, and the door 11 that is used...
