Problems solved by technology

[0020] However, in the above dryer, when the drum 30 is stuck by the drying object and stops rotating, the motor 40 and the fan 28 also stop rotating at the same time, but the heater 24 continues to generate heat, so the reliability of the entire product is greatly reduced. There is also a risk of fire

[0073] Such as Figure 10 As shown, the process flow of the first embodiment of the drying machine control method of the present invention: put the drying material into the drum 60, then close the door 59, and then start the drying machine. At this time, the motor 70 is driven, and the rotating shaft 71 is also rotating .

[0074] At this time, the hall sensor 122 detects the rotational speed of the rotor or the rotating shaft 71 of the motor, and outputs the rotational speed signal of the rotor or the rotating shaft 71, so that the control unit 98 turns on the heater 62 (S50, S51)

[0075] The rotating shaft 71 rotates the drum 60 through the conveyor belt 72 , and the drum 60 lifts the dried objects placed inside through the lifting member 84 to the upper side, and the dried objects fall back due to their own weight.

[0076] In addition, when the fan 64 rotates, the air outside the casing 54 is sucked into the air intake hole 58a, and when passing through the inside of the...

Abstract

The invention discloses a drying-machine and the controlling means, generator driving roller and fan of drying-machine, the drying-machine of this invention can detect whether the generator rotating or not and the revolution rate, controlling open or close of heater by this, preventing the heater generate superheat, reaching the effect of improve users' degree of credibility.

Description

technical field [0001] The invention relates to a dryer, in particular to a dryer capable of preventing overheating of a heater and a control method thereof. Background technique [0002] Generally speaking, a clothes dryer is an electrical appliance that transports hot air generated by a heater to a space that holds clothes, etc., to dry clothes. It is divided into dryers that only have a drying function and dryers that include washing Functional dryer and washing machine. [0003] The above-mentioned dryers are roughly classified into exhaust-type dryers and condensation-type dryers. After the exhaust type dryer dries the dried object, the high-humidity air is discharged to the outside; after the condensation type dryer dries the dried object, the high-humidity air is condensed through the external air, and Circulate to dry goods. [0004] Such as Figure 1 to Figure 3 As shown, the existing dryer includes: a base 2 constituting the bottom; located above the base 2, whi...
