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
The present invention relates to a kind of ventilation fan, refer in particular to a kind of controlling method of bathroom heating and ventilating fan.
Background technique
As shown in Figure 1, be known bathroom heating and ventilating fan 1.This type of ventilation fan is installed in the bathroom, by pipeline and the outdoor connection that connects, and then changes the air in bathroom, and makes the warm ventilation fan in bathroom by heater.
Below the framework 10 that does not form the casing shape, be provided with opening, opening portion below the framework is provided with the face shield 20 of taking air port 21 and air sucking mouth 22 out of, three parts are housed in the framework, be respectively the first portion 30 that is provided with ventilation gas fan 31, be provided with the second portion 40 and the third part 50 that is provided with heater 51 of circulation gas fan 41.
Wherein the ventilation gas fan 31 of first portion 30 is communicated with outdoor by framework 10 openings 11 and pipeline, by the gas fan 31 of taking a breath from the air sucking mouth 22 air-breathing after-blow of face shield 20 to outdoor;
The circulation gas fan 41 of second portion 40 is communicated with the third part that heater 51 is installed 50, circulation gas fan 41 from the air sucking mouth 22 air-breathing after-blow of face shield 20 to third part 50, third part 50 is communicated with by the exhaust outlet 21 of opening and face shield 20, and air is heated the back and blows out from this exhaust outlet 21.
Existing bathroom heating and ventilating fan like this; usually can be installed in cold place; but when start; above-mentioned heating and ventilating fan can run up moment; wind speed is very fast, and the heater of this moment is not heated yet fully, so; the cold wind that blows out can directly blow to the people, the people is felt cold and uncomfortable.
Therefore, a kind of ventilation fan that blows out warm wind just becomes people's hope.
Summary of the invention
Main purpose of the present invention is to provide a kind of controlling method of bathroom heating and ventilating fan, can make bathroom heating and ventilating fan blow out warm wind all the time.
Secondary objective of the present invention is to provide a kind of controlling method of bathroom heating and ventilating fan, can improve the Security of bathroom heating and ventilating fan.
For achieving the above object, the invention provides a kind of controlling method of bathroom heating and ventilating fan, it is characterized in that: with switching signal, temperature signal is as input unit, and microprocessor is as control unit, motor, heater is as output unit, by microprocessor control within a certain period of time, when the temperature of heater was lower than setting initial temperature t1, the blower fan of ventilation fan was to be lower than the speed operation of normal air quantity.Promptly, there is a thermal starting function by microprocessor control in the present invention, can make system before heater is fully heated, before to 20 degree, blower fan is with low cruise, treat just to move after it is fully heated 20 degree, thereby guarantee the comfort level of user when using this product with normal speed.
The controlling method of described bathroom heating and ventilating fan, it is characterized in that, after microprocessor receives the signal that functional switch opens, detect by the temperature of temperature transducer heater, when the temperature of heater is lower than the setting initial temperature, processor sends stop signal and gives motor controller, and the control blower fan stops a period of time.By above-mentioned hold function, can reduce heat radiation, allow the heater table surface temperature obtain fast rise.
The controlling method of described bathroom heating and ventilating fan is characterized in that, when microprocessor sends stop signal to before the motor, sends an opening signal by microprocessor earlier and gives motor controller, stops after the control motor is opened again.Like this, blower fan can be opened earlier, as runs at high speed 2 seconds, and then stops 10 seconds, thinks in the time of so just can avoiding the user to use this product that blower fan is damaged and does not work by mistake.
The controlling method of described bathroom heating and ventilating fan, it is characterized in that, when microprocessor control motor moves with low air quantity, monitor the variation of heter temperature in real time by temperature transducer, when detected temperature is higher than setting initial temperature t1, microprocessor sends the signal that can normally move and gives motor controller, and the control motor is with the speed operation of normal air quantity.Like this, temperature inductor is higher than initial temperature in the temperature that detects heater, and when spending as 20, the control blower fan runs at high speed, thereby avoids heter temperature to continue to raise fast, guarantees the normal use of product.
The controlling method of described bathroom heating and ventilating fan, it is characterized in that, when heter temperature during greater than initial temperature t1, when blower fan recovers the operation of normal air quantity, in detection time of setting in the T1, microprocessor still detects temperature, is lower than and sets when keeping temperature t 2 when detecting heter temperature, send signal by processor and give motor controller, the control motor is again with low air quantity speed operation.Like this, in detection time, in 30 seconds, drop to the maintenance temperature, when following, can control blower fan, allow the heater intensification fast, feel the discomfort of cold wind when avoiding the user to use again with low cruise as 15 degree if detect heter temperature.
The controlling method of described bathroom heating and ventilating fan, it is characterized in that when the T1 end of setting detection time, at this moment no matter how many microprocessors is by the detected heter temperature of temperature inductor, the capital is sent signal and is given motor controller, and the control motor moves with normal air quantity.Like this, in detection time, in 30 seconds, can be after the operation thermal starting, how no matter how detected temperature changes, and all sends the SC sigmal control blower fan and moves with normal air quantity, avoids the deviation of temperature to cause heat-energy losses.
The controlling method of described bathroom heating and ventilating fan, it is characterized in that, when in a single day microprocessor detects switch and the satisfied condition of setting of temperature signal, blower fan enters when hanging down the operation of air quantity speed, can send pulse signal and give led controller, control LED lamp begins flicker, just closes when stopping the thermal starting function.Like this, the user can see that a LED lamp as glimmering with 0.5 second the frequency in bright 0.5 second/pass, helps the state that understanding system is moving.
The controlling method of described bathroom heating and ventilating fan; it is characterized in that,, be higher than when setting protection temperature t 3 if microprocessor detects temperature by temperature inductor at normal air quantity run duration; can send signal gives heater controller and picks up counting; during this period, no matter how how temperature changes, and heater all will cut out by force; after treating regularly to finish; processor sends control signal corresponding again according to testing result, finishes to jump out the next circuit of wait then and judges.Like this; when temperature inductor can be higher than the protection temperature detecting heter temperature; when spending as 40; closed heater by force 2 minutes, detected temperatures then is if temperature is more than or equal to 40 degree; continue to close heater so; if temperature reopens heater so below 40 degree, guarantee the normal use of product.
In sum, the invention has the advantages that in heter temperature and cross when low, temporarily do not dry, to guarantee that the wind that blows out is hot blast all the time.
