Problems solved by technology

[0024] When the dryer is working, if the user opens and closes the door, the inflow of outside air will cause abnormal temperature
However, the conventional technology is unable to detect the above situation, which easily leads to misjudgment that the heater is abnormal
[0025] That is, since the conventional technology cannot detect temperature abnormality caused by external influences, the heater is still in normal operation, causing the dryer to operate incorrectly, resulting in a decrease in drying performance

Embodiment Construction

[0046] The present invention provides a dryer, which includes a heater and a temperature detection unit. The dryer also includes: an input unit 100 for the user to input control commands; a door detection unit 200 for detecting the opening action; controlling the heater to work , and according to the detection result of the door detection part, change the initial working time of the heater, receive the temperature value that changes along with the heater driving from the temperature detection part at the same time, the microprocessor 300 that judges whether the operation of the heater is abnormal; according to the microprocessor The control signal of the processor 300 shows the abnormal display part 700 of the abnormal state in the heater operation; wherein the input part 100, the door detection part 200 and the temperature detection part 800 are connected to the input end of the microprocessor 300, and the output end of the microprocessor 300 The abnormal display part 700 is c...

Abstract

The drier includes heater, temperature detecting unit, input unit,door detecting unit, microprocessor and abnormality display unit. The input unit, the door detecting unit and the temperature detecting unit are connected to the input of the microprocessor; and the abnormality display unit and the motor and heater driving unit are connected to the output of the microprocessor. The detection method includes the following steps: detecting the door opening action; timing the reference time; judging whether to have abnormality in the heater, etc. When door opening action is detected, the reference time for the heater to operate is reset, so as to avoid the error judgment of heater abnormality caused by temperature descent owing to opening door and other outer factors. The present invention can raise stoving effect of the drier.

Description

technical field [0001] The invention relates to a dryer, in particular to a dryer and a method for detecting abnormality of the heater of the dryer. Background technique [0002] Generally, a clothes dryer is a device for drying wet clothes after washing. Recently, the demand for clothes dryers is increasing. [0003] The structure of the traditional technology dryer will be described below with reference to the accompanying drawings. [0004] figure 1 It is a side sectional view of a traditional technology dryer. [0005] Such as figure 1 As shown, the structure of the traditional technology dryer is: the front of the shell 1 is the input port 3, and the inside of the shell 1 is provided with a rotatable drum 2, and the laundry thrown in is housed in the drum 2. The door 4 for opening and closing the input port 3 is equipped with on the input port 3 . [0006] A motor 5 is provided in the upper part of the casing 1 . When the dryer is working, the power of the motor ...
