Detailed description of the invention
Below in conjunction with accompanying drawing, a kind of heater of the present utility model is further described.
A kind of heater, comprises the housing 1 with an air outlet 13, the heater 2 being installed on housing 1 inside and is arranged at the cell type tube-axial fan (axial flow fan) 3 at heater 2 rear portion, as shown in Figure 1 and Figure 2.
In the present embodiment, heater 2 preferably adopts PTC(Positive Temperature Coefficient, positive temperature coefficient) heater.PTC heater is Novel electric resistive ceramic heating element, and long, energy-conservation, the flames of anger of constant temp. warming, natural life-span, security performance are good, caloric value easily regulates and by the incomparable advantage of a series of traditional electrical thermal elements such as power supply voltage influence is little.
Housing 1 comprises the side cover 12 of the generally u-shaped face-piece of cross section 11 and closed face-piece 11 both-side opening for housing; The bottom of face-piece 11 sets out air port 13, and side cover 12 is screwed in face-piece 11 both sides, and close face-piece 11 both ends open, heating part is then installed within the case 1 by side cover.The motor 3 of cell type tube-axial fan is fixed on above face-piece 11, and motor 3 thickness of this cell type tube-axial fan is little more than centrifugal fan of the prior art, can substantially reduce whole height.In order to increase air output, the present embodiment is provided with the motor 3 of two cell type tube-axial fans.
Concrete, heater 2 comprises warm braw block 21 and temperature controller 22.As shown in Figure 3.Warm braw block 21 is one by the metal strip sheet of electric heat production.Side cover 12 be provided with towards face-piece 11 inside multiple for accommodating, the slot 121 of fixing warm braw block 21 end.Be specially, each side cover 12 towards the inner side of housing 1, one frame structure is set, slot is formed in described frame structure, contains temperature controller 22 between frame structure and sidewall in the receiving space formed.In the present embodiment, owing to being provided with 4 warm braw blocks 21, the position therefore each side cover 12 being provided with 4 slots, 121, two side cover 12 slots 121 is mutually corresponding, be arranged in air outlet 13 place in face-piece 11 4 warm braw block 21 parallel side-by-side, thus air-out is heated.In addition, warm braw block 21 both ends are provided with the pin for coordinating slot 121, and form energising interface 212 in the stage casing of pin.When the pin of the end of warm braw block 21 inserts slot 121, it is inner that energising interface 212 enters side cover 12 thereupon.The both sides, stage casing of warm braw block 21 are then provided with heat conduction grid 211, heat conduction grid 211 about warm braw block 21 symmetry arrangement, for fast heat being delivered in the middle of air-out.Electrically connect as parallel connection between 4 warm braw blocks 21, four the energising interfaces 212 be in same side cover 12 are linked together by wire.
In order to better control the temperature of air-out, temperature controller 22 comprises the first normally closed temperature controller 221 and Chang Kai second temperature controller 222, it is other that these two temperature controllers are all arranged on warm braw block 21, be screwed on side cover 12, the temperature of warm braw block 21 can be responded to well, thus leaving air temp is arranged.Concrete, in electrical connection, the first temperature controller 221 is connected between external power source and heat conduction grid 211, because the first temperature controller 221 is normally closed temperature controller, when temperature is lower than the first temperature controller 221 setting value, the first temperature controller 221 is all in conducting state, otherwise is then in off-state.In actual use, when the temperature that warm braw block 21 temperature sets lower than the first temperature controller 221, warm braw block 21 is all in running order, when having exceeded design temperature then power cutoff, warm braw block 21 quits work, and prevents from causing because warm braw block 21 temperature is too high that product internal temperature is too high causes security incident.Second temperature controller 222 is connected between the motor 3 of external power source and cell type tube-axial fan, and the second temperature controller 222 is the temperature controller often opened, and its principle is contrary with normally closed temperature controller, namely when temperature disconnects lower than during setting value, higher than conducting during setting value.The second temperature controller 222 in the present embodiment prevents that the air-out when just opening heater is excessively cold causes user uncomfortable, and can also blow a period of time, until warm braw block 21 temperature is reduced to below the temperature set by the second temperature controller 222 after shutoff warm braw block 21.
Under preferable case, the critical-temperature of the first temperature controller 221 is 85 DEG C, and the second temperature controller 222 is then 65 DEG C.Therefore can ensure that the leaving air temp of heater is between 65 DEG C ~ 85 DEG C.
Under preferable case, in order to prevent scalding and the loss of heat, face-piece 11 two side is provided with the heat insulation structural 14 that at least relative with heater 2 position, the two side of insulated cavity 14 face-piece is formed as bilayer.
By reference to the accompanying drawings embodiment of the present utility model is explained in detail above, but the utility model is not limited to above-mentioned embodiment, in the ken that those of ordinary skill in the art possess, various change can also be made under the prerequisite not departing from the utility model aim.
