The invention discloses a filter screen detection circuit in a clothes dryer, which belongs to the technical field of circuit design. The filter detection circuit in the clothes dryer includes an infrared detection module, an air temperature detection module, an MCU module, an LED warning module and a power conversion module. The infrared detection module is used to detect the blockage of the filter screen; the air temperature detection module is used to capture real-time temperature information; the MCU module processes the detection signals of the infrared detection module and the air temperature detection module; the LED warning The module produces different lighting effects according to the processing results to serve as a warning; the power conversion module converts the external voltage into the working voltage of the filter detection circuit in the clothes dryer. The filter detection circuit in the dryer can quickly detect whether the filter of the dryer is full, and capture temperature changes in real time, and remind the user through the LED warning module, which is simple and accurate, and the cost is low.
Description
technical field [0001] The invention relates to the technical field of circuit design, in particular to a filter detection circuit in a clothes dryer. Background technique [0002] The clothes dryer is a cleaning household appliance that uses electric heating to evaporate and dry the water in the washed clothes immediately. With the improvement of people's quality of life, more and more clothes dryers have entered people's lives. [0003] At present, the control circuit of the clothes dryer on the market is relatively simple. Generally, only a mechanical timer is provided, and the user can set the working time of the clothes dryer by himself, and it will end automatically when the time comes. This kind of simple clothes dryer circuit intelligently realizes a simple timed drying function, but it cannot detect the amount of clothes placed and the internal temperature, let alone realize the human-computer interaction function, which has certain disadvantages.
