Abstract
The utility model relates to a bidirectional fan which comprises a base, a supporting frame, a motor, fan blades and protective discs, wherein a forward fan and a backward fan are arranged on the supporting frame of the fan; the forward fan is opposite to the backward fan; the forward fan and the backward fan respectively comprise the fan blades and the protective discs; and the fan blades are fixed on an output shaft of the motor. When the bidirectional fan is used, people at different positions can be blown, and the utilization ratio of the fan is increased.
Description
Technical field
The utility model relates to a kind of household electric appliance, particularly a kind of two-way fan.
Background technique
Fan is a kind of household electric appliance of each family's indispensability in summer, and fan both can be used for driving away summer heat, and also can be used for accelerating indoor air ventilation, improved indoor air quality.But, at present, existing fan generally all has only a fan blade, and promptly fan intelligence is to a fixing direction blowing, though existing fan can be swung, but hunting range only has 180 degree, the fan rear 180 the degree scopes in be fan blow less than the zone, if blow to the zone of fan, then need to re-use simultaneously another fan and dry, cost is higher, and uses very loaded down with trivial details.
Summary of the invention
The purpose of this utility model be at the existing fan described in the technology of Beijing exist can only be to problem than the zonule blowing, provide a kind of can be to the fan of blowing on a large scale.
The realization the technical solution of the utility model is as follows:
A kind of two-way fan, it comprises base, supporting frame, motor, fan blade and protective plate, the supporting frame of described fan is provided with forward direction fan and back to fan, the forward direction fan is opposite to fan directional with the back, forward direction fan and back comprise fan blade and protective plate respectively to fan, and fan blade all is fixed on the output shaft of motor.
In order to make fan can blow to all directions, be provided with the whirligig of control fan substantially horizontal rotation in the described fan.
The beneficial effects of the utility model are because the supporting frame of fan of the present utility model is provided with forward direction fan and back to fan, the forward direction fan is opposite to the direction of fan with the back, therefore, when machine operation, the output shaft of motor drives the forward direction fan simultaneously and rotate to the fan blade of fan the back, therefore, can blow simultaneously in the opposite direction, because in fan, be provided with the whirligig of control fan substantially horizontal rotation, therefore, can make the people who is in diverse location can both blow to wind, increase the utilization ratio of fan.
Description of drawings
Fig. 1 is a schematic representation of the present utility model;
Among the figure, 1 is base, and 2 is supporting frame, and 3 is motor, and 4 is fan blade, and 5 is protective plate, and 6 is whirligig, and 7 is the forward direction fan, and 8 is that the back is to fan.
Embodiment
With reference to a kind of two-way fan shown in Figure 1, it comprises base 1, supporting frame 2, motor 3, fan blade 4 and protective plate 5, the supporting frame 2 of described fan is provided with forward direction fan 7 and back to fan 8, forward direction fan 7 is opposite to fan 8 directions with the back, forward direction fan 7 and back comprise fan blade 4 and protective plate 5 respectively to fan 8, and fan blade 4 all is fixed on the output shaft of motor 3.In order to make fan can blow to all directions, be provided with the whirligig 6 of control fan substantially horizontal rotation in the described fan.Because the supporting frame of fan of the present utility model 2 is provided with forward direction fan 7 and back to fan 8, forward direction fan 7 is opposite to the direction of fan 8 with the back, therefore, when motor 3 work, the output shaft of motor 3 drives forward direction fan 7 simultaneously and rotate to the fan blade 4 of fan 8 back, therefore, can blow simultaneously in the opposite direction, because in fan, be provided with the whirligig 6 of control fan substantially horizontal rotation, therefore, can make the people who is in diverse location can both blow to wind, increase the utilization ratio of fan.
Claims (2)
1. two-way fan, it comprises base, supporting frame, motor, fan blade and protective plate, it is characterized in that: the supporting frame of described fan is provided with forward direction fan and back to fan, the forward direction fan is opposite to fan directional with the back, forward direction fan and back comprise fan blade and protective plate respectively to fan, and fan blade all is fixed on the output shaft of motor.
