Abstract
The utility model provides a temperature-sensing and automatic speed-regulating electric fan. On the basis of the traditional electric fan, the temperature-sensing and automatic speed-regulating electric fan comprises a temperature sensor, a processing control module and a frequency-changing speed regulator. The temperature sensor is used for detecting the temperature of ambient air and sending the temperature to the processing control module by an electric signal. The processing control module compares a temperature signal with the set temperature range and controls the working of the frequency-changing speed regulator according to the comparing result so as to control the rotating speed of a motor of the electric fan.
Description
Technical field
The utility model relates to household appliance technical field, refers to that especially a kind of temperature-sensitive is from the speed governing electric fan.
Background technique
Electric fan is extensive use of by people as a kind of household electric appliance of enjoying the cool, ventilating.An existing patent No. is 99245536.7 and is called that the model utility of " regularly throw-over electric fan " discloses the regularly electric fan of speed-regulating function of a kind of novel band, it is to insert a regularly alignment circuit before the motor of electric fan, its timer has two contacts, is connected to speed regulator K1, K2 respectively.This timing speed governing electric fan had both kept the original function of electric fan, made the timing controlled effect of electric fan more perfect again.
Though above-mentioned patented product has increased regularly throw-over function on traditional basis, but not having energy and ambient environmental conditions (temperature etc.) to change connects, can occur that temperature has lowered but the rotating speed of electric fan is also very high, bring adverse effect to the user, especially can give the healthy influence that brings in when sleep as the user.Above-mentioned in addition patent belongs to step speed regulation, and adjustment range is subjected to certain limitation.
Summary of the invention
Technical problem to be solved in the utility model is at above-mentioned present situation, provide a kind of can be along with temperature variation the electric fan of automatic stepless speed-regulating, convenient user's use.
The utility model solves the problems of the technologies described above the technological scheme that is adopted: on the basis of traditional electric fan, and mounting temperature sensor, processing and control module, variable-frequency governor.
As improvement, described temperature transducer is to be used for the temperature of testing environment air, sends to processing and control module by electrical signal, and processing and control module is with the temperature range comparison of temperature signal and setting, according to the work of comparison result control variable-frequency governor, thus the rotating speed of control fan motor.
As improving, variable-frequency governor can be in " 0-maximum (top) speed " scope, the rotating speed of stepless adjustment fan motor again.
As further improvement, the user can be according to the needs setting temperature scope of oneself.Such as, user's range of set temperature is 20-30 ℃, and fan speed is 0 when ambient temperature≤20 ℃, and fan speed is a maximum (top) speed when ambient temperature 〉=30 ℃, when ambient temperature range was 20-30 ℃, electric fan was at the stepless adjustment rotating speed of " 0-maximum (top) speed " scope internal linear.
Compared with prior art, the utility model is by mounting temperature sensor, processing and control module, variable-frequency governor on the basis of traditional electric fan, realized adjusting automatically the function of rotating speed along with variation of ambient temperature, make and very strong practical and popularizing value is arranged the convenient and hommization of use of electric fan.
Description of drawings
Fig. 1 is the utility model embodiment's a principle schematic;
Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As shown in Figure 1, the utility model is that temperature transducer (1) is installed on the basis of traditional electric fan, processing and control module (2) and variable-frequency governor (3). temperature transducer (1) is to be used for the temperature of testing environment air, by datawire electrical signal is sent to processing and control module (2), processing and control module (2) is connected with variable-frequency governor (3) line, can be with the temperature range comparison of temperature signal and setting, according to comparison result control variable-frequency governor (3) work, variable-frequency governor (3) is connected with fan motor (4) line, can control its rotating speed and adjust in " 0-maximum (top) speed " scope.
In actual use, the user can be according to the needs input setting temperature scope of oneself.Such as, user's range of set temperature is 20-30 ℃, processing and control module (2) is 0 by variable-frequency governor (3) control fan motor (4) rotating speed when ambient temperature≤20 that temperature transducer (1) records ℃, the control fan speed is a maximum (top) speed with should ambient temperature 〉=30 ℃ the time, when ambient temperature range was 20-30 ℃, fan motor (4) was at the stepless adjustment rotating speed of " 0-maximum (top) speed " scope internal linear.
Claims (1)
1. a temperature-sensitive is from the speed governing electric fan, be that temperature transducer (1), processing and control module (2) and variable-frequency governor (3) are installed on the basis of traditional electric fan, it is characterized in that: temperature transducer (1) is connected with processing and control module (2) by datawire, processing and control module (2) is connected with variable-frequency governor (3) line, and variable-frequency governor (3) is connected with fan motor (4) line.
