But in this prior art laundry dryer, since the thermistor not shown in the figure is a low-temperature thermistor, it cannot control the high temperature caused by the heater not shown in the figure. A high temperature state at a specific temperature, so there is a danger of temperature rise inside the drum 1

The invention discloses a temperature control device and a temperature control method of a condensing clothes dryer. The control device includes a temperature detection part capable of detecting the internal temperature of the drum; a first and a second thermistor capable of adjusting the amount of current supplied to the heater when the temperature value detected by the temperature detection part is lower than or higher than a set reference temperature; and The microprocessor that can control the drive of the first and second thermistors and the heater drive can be controlled based on the detected temperature of the temperature detection unit. The temperature control device and temperature control method of the condensing clothes dryer provided by the present invention have the following effects: first, temperature control under different conditions can be controlled in different drying intervals by using multiple thermistors for temperature control. Second, different temperature control can be carried out under high and low temperature conditions to prevent the danger caused by temperature rise. Third, since the danger of temperature rise can be prevented, drying performance can be improved.
Description
technical field [0001] The present invention relates to a clothes dryer, in particular to a temperature control device and the temperature control device of the condensation clothes dryer which can control the temperature according to the drying interval in the condensation clothes dryer which circulates the internal air for drying. temperature control method. Background technique [0002] Generally speaking, a clothes dryer is a device that can send hot air generated by a heater to the inside of a drum to absorb the moisture of the object to be dried in the drum, thereby drying the object to be dried. Clothes dryers can be broadly classified into exhaust-type clothes dryers and condensation-type clothes dryers according to how moisture is absorbed in the humid air generated when drying objects. The exhaust type clothes dryer adopts the method of discharging the humid air discharged from the drum to the outside of the dryer; while the condensation type clothes dryer adopts ...
