Description
Technical field
The utility model relates to a kind of warmer, especially relates to a kind of PTC warmer, belongs to a kind of heating system.
Background technology
The general structure of PTC warmer is: comprise housing, be provided with on the housing into and out of the air port, be provided with blowing device and air channel in the housing, the air outlet place is provided with the PTC heating block, blowing device blows out wind from the air channel, and by blowing out from air outlet after the heating of PTC heating block.Yet often have certain step between air outlet and the bottom, air channel, in the time of blowing device work, air-flow blows at this step can produce noise, affects user's rest or use, also hinders flowing of air-flow simultaneously, impact blowing effect.
The utility model content
The purpose of this utility model is to overcome above shortcomings in the prior art, and provides a kind of reasonable in design, little, the smoothly warmer of drying of noise.
The technical scheme in the invention for solving the above technical problem is: this warmer comprises housing, blowing device, air channel, heating block, air outlet and air inlet, described air inlet and air outlet are separately positioned on the two ends of housing, described air channel surrounds and is arranged in the housing by air duct board, this air channel and air outlet connect, described blowing device is installed in the air channel, described heating block is installed in the air outlet place, it is characterized in that: also comprise the wind-guiding piece, described wind-guiding piece left end is connected with the bottom, air channel, and right-hand member is connected with bottom's end of air outlet.
Wind-guiding piece described in the utility model has the inclined-plane, and the angle on this inclined-plane is that 10 degree are to 20 degree.
The angle a on inclined-plane described in the utility model is 14 degree.Purpose is that the air-out smoothness reduces noise simultaneously.
Wind-guiding piece described in the utility model up and down both sides is head and afterbody, and the sideline of described head surface is straight line, and the sideline of tail surface comprises camber line and recess.During installation on the shape of head and afterbody and the air duct board corresponding position match, reduce the fit-up gap, reduce noise.
The thickness b of wind-guiding piece described in the utility model is not less than the bottom, air channel to the height h of air outlet lower sideline.
The utility model compared with prior art has the following advantages and effect: simple in structure, reasonable in design, smooth by the air-out that is arranged so that the warmer complete machine of wind-guiding piece, noise reduces, and guarantees user's normal rest, has also improved the blowing effect simultaneously.
