Description
Technical field
The present invention relates to a kind of fan.In a preferred embodiment, the present invention relates to a kind of produce hot air flow can heating type fan.
Background technique
Traditional domestic fan generally comprises around the vane group of axis rotation and the motor of drive vane group rotary work.Motion and the circulation of air stream have produced " air-cooled ", because heat is dispersed and made user experience nice and cool effect by convection current and evaporation.
The fan of existing various sizes and shape.The diameter of ceiling fan is greater than lm conventionally, and conventionally installs in the mode being suspended on ceiling board, to provide downward air-flow to make room cooling.Bracker fan can arbitrarily be placed and portability conventionally.Floor model tower fan generally includes shell elongated, vertical extension, and covering the vane group for generation of air stream, use swing mechanism with the outlet of rotary tower type fan in case air stream can inswept room broad space.
Fan-type heater generally includes some and is positioned at heating element after rotation blade or above, makes user can heat the air stream that rotation blade produces.Heating element is generally the form of heat coil or fever tablet.Adjustable thermostat or the output power setting that some are predetermined, make user can control the temperature of the air stream of launching from fan-type heater.
The air stream that the rotation blade of fan-type heater produces is inhomogeneous conventionally.This is the surperficial variation towards outside due to blade surface or fan-type heater, and these variations cause the generation of the air stream of turbulent flow or " waves surging turbulently ", and this air stream can be perceived as a series of air pulse, and this allows user feel under the weather.Another shortcoming that the turbulent flow of air stream causes is that the heating effect of fan-type heater can weaken rapidly with distance.
In family environment, due to the restriction in space, expectation be that utensil will be as far as possible little and compact as far as possible.The less desirable user of being can touch any moving element, as blade.Fan-type heater conventionally covers on blade and heat coil in cage or in housing with holes to prevent user from touching the blade of motion or boiling hot heat coil and comes to harm, but the part of this sealing is to be difficult to clean.Therefore, during using fan-type heater, a large amount of dusts or other chips can gather in the enclosure with heat coil on.When heat coil is activated, the temperature of the outer surface of heat coil can rise rapidly, and especially, in the time that the output power of heat coil is higher, the temperature of its heat coil can exceed 700 DEG C.Therefore,, during using fan-type heater, some dusts that rest on heat coil can be burnt, and cause fan-type heater to give off an unpleasant smell.
