Problems solved by technology
[0004] Although the above method can solve the traditional problem, the delay time of this control method is manually adjusted by the user and the extended operation time of the fan is fixed, so it cannot be flexibly increased according to the length of time and different purposes of using the confined space. Or shorten the delay time (such as taking a bath, using it for a long time when using a tuba, producing a lot of water vapor, and a lot of odors. It takes a long delay to effectively remove moisture and odors. Relatively, if you wash your hands or use a trumpet Short time, only a short delayed start is sufficient
Unable to flexibly automatically adjust the delayed closing time, there will be a risk of wasting energy due to excessive ventilation; or the shortcomings of odor and moisture residue due to insufficient ventilation)
And if you want to flexibly change and extend the time of turning off the fan according to the purpose of using the bathroom or toilet, the user must remove the fan from the ceiling or remove the light switch panel, and adjust the delay time according to the purpose of use each time. It is quite inconvenient to use and increases the trouble of adjustment

Embodiment Construction
[0028] The aforementioned and other technical contents, features and effects of the present invention will be clearly presented in the following detailed description of preferred embodiments with accompanying drawings.
[0029] A preferred embodiment of the present invention is as shown in Figure 1, the fan control system 1 is set in a closed space (not shown in the figure, such as a bathroom space) for ventilation, it is set in a power supply with a power switch S 10 and the fan 13, and includes a delay timing unit 120, a cycle timing unit 123, an end timing unit 124, a control unit 121, and a comparison table 122.
[0030] The power supply 10 is, for example, commercial power, which can be further connected to other electronic devices 11 (such as lamps) installed in the confined space, and is controlled by a power switch S to turn on or off the electronic devices.
[0031] The control unit 121 is respectively connected with the power switch S, the delay timing unit 120, the ...

The invention relates to a control method for fan, which is applied in the control unit of control system for fan. The control unit opened by one switch can control the opening of fan relatively and the closing of fan relatively. The control method comprises following procedures that first, the opening message for switch is received, the opening of fan is controlled, after a long time for usage, the closing message for switch is received; second, according to the usage time, relative delaying time according with the usage time is determined; finally, the closing of fan is controlled after the delaying time. So, the delaying time for closing the fan can be adjusted according to the usage time and is more practical.
Description
technical field [0001] The invention relates to a fan control method, in particular to an intelligent fan control method. Background technique [0002] At present, the ventilation fan installed in a closed space (such as a bathroom space) for removing peculiar smell and moisture is typically controlled by manually turning on and off a power switch when entering or leaving a closed space or a bathroom. Ventilation fans can discharge odors and moisture in confined spaces or bathrooms, but after the bathroom equipment is used and the power switch is turned off, the residual odors or moisture cannot be removed. and humidity have a limited effect. [0003] Therefore, improved methods are proposed in known patents. For example, U.S. Patent No. 6,326,882 issued on December 4, 2001 provides an improved fan control method. Turn off after running for a predetermined period of time, which can prolong the indoor ventilation time and improve the effect of improving odor and dehumidific...
