Abstract
Disclosed is an energy saving household electric fan, which comprises an electric fan main body, a direct current brushless motor, an AC-DC conversion circuit board, and a fan blade. First, the electric fan main body is provided with a mounting groove for mounting the AC-DC conversion circuit board, and then the AC-DC conversion circuit board is mounted in the mounting groove on the electric fan main body. The AC-DC conversion circuit board is mounted with the direction current brushless motor, and finally the fan blade is mounted on the shaft of the direct current brushless motor.
Description
Technical field
The present invention relates to household appliance technical field, refer more particularly to a kind of domestic energy-conserving electric fan.
Background technique
Electric fan is as household electric appliance commonly used, existing by a large amount of universal use of ordinary family, the working life of electric fan and energy-conservation situation, the focus that also is not to use the person to pay close attention to always.The working life of electric fan and energy-conservation situation, the overwhelming majority depend on the working life and the energy-conservation situation of motor.Because the driving of electric fan depends primarily on the driving of motor, so the working life of motor and energy-conservation working life and energy-conservation situation for electric fan are extremely important.Existing domestic electric fan all adopts motor directly to connect ac power supply and drives, and its shortcoming is to be subjected to magnetic interference big, and the life-span of motor is short, and power consumption is high simultaneously.
Summary of the invention
The object of the present invention is to provide a kind of use dc brushless motor to drive, can greatly reduce the power consumption of electric fan, simultaneously the domestic energy-conserving electric fan that can greatly promote its working life.
For achieving the above object, the invention provides a kind of domestic energy-conserving electric fan, it comprises an electric fan main body, a direct current brushless electric machine, an ac-dc converter circuit plate, a fan rotating vane.One mounting groove that the ac-dc converter circuit plate can be installed at first is set on this electric fan main body, this ac-dc converter circuit plate is installed in the mounting groove on this electric fan main body.On this ac-dc converter circuit plate, install a direct current brushless electric machine, at last this fan rotating vane is installed on the axle on this dc brushless motor.
Description of drawings
Fig. 1 is the stereoscopic-state structural drawing of domestic energy-conserving electric fan of the present invention.
Fig. 2 installs the stereoscopic-state structural drawing of ac-dc converter circuit plate for domestic energy-conserving electric fan of the present invention.
Fig. 3 is the stereoscopic-state structural drawing of the dc brushless motor of domestic energy-conserving electric fan of the present invention.
Embodiment
See also Fig. 1 to Fig. 3, a kind of novel domestic energy-conserving electric fan, it comprises an electric fan main body 1, a direct current brushless electric machine 2, an ac-dc converter circuit plate 3, one fan rotating vanes 4.One mounting groove that ac-dc converter circuit plate 3 can be installed at first is set on this electric fan main body, this ac-dc converter circuit plate 3 is installed in the mounting groove on this electric fan main body 1.On this ac-dc converter circuit plate 3, install a direct current brushless electric machine 2, at last this fan rotating vane 4 is installed on the axle on this dc brushless motor 2.
Working principle of the present invention is as follows: after connecting ac power supply, Ac converts direct current to by ac-dc converter circuit plate 3, and dc powered dc brushless motor 2 rotates and reaches the purpose that the fan rotating vane 4 of drive installation on 2 of this dc brushless motors rotates.
The present invention has following advantage:
1, easy assembling simple in structure.
2, the stream brushless electric machine is as the driving of electric fan, can utilize long service life excellent of dc brushless motor Point improves the service life of electric fan greatly.
3, use the driving of dc brushless motor, can reduce power consumption, compare of the driving of identical powerful AC motor as electric fan as electric fan, energy-conservation more than 20%.
Claims (2)
