Abstract
The utility model relates to an electric cold and hot airing fan. The wind from the regular electric fan is cool, so the regular fan can only be used in summer, the regular fan is laid idle in winter, and the air conditioner used in winter can not be popularized because the cost of the air conditioner is high. The utility model, which comprises a supporter, a fan electromotor, and impellers, is characterized in that a flow collecting cover is arranged in front of the impellers; a wind guiding board is arranged in the flow collecting cover; a heater which is made of PTC semiconducting ceramic elements is arranged in front of the flow collecting cover. The utility model which adopts PTC semiconducting ceramic as heating elements has the characteristic of keeping constant temperature automatically and no flame, therefore, the utility model has the advantages of high heat exchanging efficiency, energy saving, and long service life.
Description
The utility model is a kind of civilian electric fan, particularly a kind of can fanning with the matching used cold and hot wind-powered electricity generation of common electrical fan.
What general electric fan blew out is cool breeze, therefore can only use in summer.Will leave unused for a long time in winter, the air-conditioner that use winter then can not get popularizing because of selling at exorbitant prices.
The purpose of this utility model provides a kind of cold and hot wind-powered electricity generation fan, and it can overcome existing shortcoming in the prior art, and use as box fan summer, can be used as Hot-air fan winter and use, and price is significantly less than air-conditioner.
The purpose of this utility model is achieved in that it comprises support, fan electromotor and impeller, it is characterized in that the conflux cover being housed in the place ahead of impeller, have induced draft plate in the conflux cover, the heater that PTC semiconductive ceramic element is made is housed in the place ahead of conflux cover, and the outer rim of impeller back cover has deep bead.
By the effect of wind that blast fan blew out by the conflux cover, make original rotatablely move to change become rectilinear motion, through the intensification of heater, the wind of being discharged by exhaust outlet promptly becomes hot blast, through testing in 20 square metres room, heats one hour, indoor temperature raises 6 ℃, power consumption 1.2 degree.Heater can be removed in summer, so just can be used as thermantidote and use.
The utility model has the advantages that: adopt the PTC semiconductive ceramic as heating element heater, have the characteristics of automatic maintenance constant temperature, the flames of anger, therefore safe and reliable, the heat exchanger effectiveness height, energy savings, and also power can be adjusted the while long service life automatically.
The utility model can be applied to desk-top and the console mode fan.
The utility model is described in further detail below in conjunction with embodiment and accompanying drawing thereof.
Fig. 1 is a side structure schematic diagram of the present utility model.
Fig. 2 is an A-A cutaway view among Fig. 1.
1 is the support of fan among the figure, the 2nd, and motor, the 3rd, impeller in the place ahead of impeller, is equipped with taper wind gathering cover 4, is provided with induced draft plate 5 in the cover, and being equipped with before the wind gathering cover with the PTC semiconductive ceramic is the heater 6 of heating element heater, before is protective cover 7 again.In the back of impeller, back cover 8 is housed, the middle part of back cover is an air inlet, outer rim is equipped with deep bead 9, prevents that wind runs off from the rear portion.
