Abstract
The utility model discloses a domestic direct current (DC) fan, which comprises fan blades and a supporting seat, wherein a motor and a control box are mounted in the supporting seat; the motor is a DC brushless motor and comprises a motor shell, wound stators and magnetic pole rotors; and an inversion module connected with the motor is arranged in the control box. The domestic DC fan adopting the DC brushless motor as a power source has the characteristics of low power consumption and long service life when being compared with the previous alternating current (AC) motors, and stepless speed regulation can be achieved by using low cost, so the use cost can be saved for a user and speed regulation convenience can be brought to the user.
Description
Technical field
The utility model relates to the fan technical field, is specifically related to a kind of household DC fan.
Background technique
At present family expenses fan on the market mostly is ac fan, with the one-way communication asynchronous motor as power source.Because energy consumption is bigger during the AC motor operation, the rotational speed regulation scope is less, and generally the used motor of ac fan is a brush motor, and working life is shorter.
Adopt direct current generator also rarely found as the family expenses fan of power source.
The model utility content
The purpose of this utility model provides a kind of family expenses fan that adopts direct current generator as power source.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of household DC fan, comprise fan blade and bearing, motor and Direct box are installed in the bearing, described motor is a dc brushless motor, form by motor housing, wound stator and pole wheel, be provided with the inversion module that is connected with motor in the described Direct box.
The beneficial effects of the utility model are: fan adopts dc brushless motor as power source, the AC motor of comparing in the past has characteristics low in energy consumption, that the life-span is long, and use lower cost just can realize stepless time adjustment, can save user cost, bring the speed governing facility for the user.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
With reference to Fig. 1, shown in, the utility model discloses a kind of household DC fan, comprise fan blade 1 and bearing 4, motor 2 and Direct box 3 are installed in the bearing 4, described motor 2 is a dc brushless motor, by motor housing 21, wound stator 22 and pole wheel 23 are formed, be provided with the inversion module 31 that is connected with motor 2 in the described Direct box 3, owing to adopt dc brushless motor as power source, compare AC motor in the past, the utlity model has low in energy consumption, the characteristics that life-span is long, and use lower cost just can realize stepless time adjustment, can bring the speed governing facility for the user saves user cost.
The foregoing description is illustrative principle of the present utility model and effect thereof only; and the embodiment of part utilization; for the person of ordinary skill of the art; under the prerequisite that does not break away from the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
