Problems solved by technology

[0006] Existing heating and ventilating fans for bathrooms like this are usually installed in cold places, but when turned on, the above-mentioned heating and ventilating fans will run at high speed in an instant, with a fast wind speed, and the heater at this time has not yet been fully heated, so , the cold wind will blow directly to people, making people feel cold and uncomfortable

Embodiment Construction

[0022] Such as figure 2 Shown is a structural frame diagram of the present invention. Switch signal 101, temperature signal 102 as input unit 100, microprocessor 201 as control unit 200, motor controller 301 controls motor 302, heater controller 303 controls heater 304, LED driver 305 controls LED306, motor controller 301, A motor 302 , a heater controller 303 , a heater 304 , an LED driver 305 , and an LED 306 serve as the output unit 300 .

[0023] Such as image 3 Shown is a schematic flow chart of an embodiment of the present invention. When the system starts (step 1000), at first the switch signal is judged (step 1001), if not, directly jumps out (step 1100) and enters other functions. If there is, start timing T1 again, be 30 seconds (step 1002) in the present embodiment, and further judge (step 1003) heater temperature, when the detected temperature is greater than the initial temperature, in the present embodiment is When 20 degrees, just do not need hot start fun...

Abstract

The invention provides a method for controlling a bathroom heating and ventilating fan, which is characterized in that: switching signals and temperature signals are taken as input units, a microprocessor is taken as a control unit, and a motor and a heater are taken as output units; and the microprocessor controls a blower of the ventilating fan to operate at a speed lower than normal air flow in a certain period when the temperature of the heater is lower than a set initial temperature. The method has the advantages that when the temperature of the heater is too low, air is not blown temporarily so as to ensure that the air blown out is hot air.

Description

technical field [0001] The invention relates to a ventilating fan, in particular to a method for controlling a heating and ventilating fan used in a bathroom. Background technique [0002] Such as figure 1 Shown, is known heating ventilation fan 1 for bathroom. This type of ventilation fan is installed in the bathroom, communicates with the outside through the connected pipe, and then replaces the air in the bathroom, and the ventilation fan that warms the bathroom through the heater. [0003] Be provided with opening below the frame 10 that does not form box shape, the opening below the frame is provided with the mask 20 of band air outlet 21 and air suction port 22, and three major parts are housed in the frame, are respectively provided with the ventilation fan 31 The first part 30, the second part 40 provided with the circulation blower 41, and the third part 50 provided with the heater 51. [0004] Wherein the ventilation blower 31 of the first part 30 communicates w...
