Figure 4 shows that the utility model embodiment relates to both cooling and heating fan and conceal the structural representation of partial shell, can find out in conjunction with Fig. 3, in housing 1, be provided with heater 50 and support the heater support bracket 60 of heater 50, concrete, be fixed with the heater support bracket 60 of heater 50 between air channel 10 and exhaust outlet 40.Heater 50 is fixed on heater support bracket 60 by the mode such as support, screw.Heater support bracket 60 is also provided with the heater compressing tablet 61 for covering heater 50 connecting lines, for example the power line being connected with heater 50 is covered below heater compressing tablet 61, be unlikely to wiring chaotic, increase integrally-built cleaning, heater compressing tablet 61 can be fixed on heater support bracket 60 by fixing column.In the present embodiment, heater 50 is preferably PTC heater, and it combines gluing and mechanical advantage, heat conduction, excellent radiation performance, and efficiency is high, safe and reliable; The material that heater support bracket 60 is preferably good insulation preformance, be difficult for heat by conduction is made.
Housing 1 is provided with the slide rail 70 that supports heater support bracket 60, in order to make the movement of heater support bracket 60 more smooth and easy, in this enforcement, preferably at the two ends of lower shell body 12, a slide rail is set respectively, the bottom of heater support bracket 60 is provided with the chute engaging with slide rail 70, is conducive to heater support bracket 60 reliable mobile on slide rail 70.In the present embodiment, slide rail 70 is preferably upwardly extending slide plate, simple in structure, is easy to the movement of heater support bracket 60.
One end of heater support bracket 60 is provided with the driven unit 80 for heater support bracket 60 is slidably reciprocated on slide rail 70 being connected with heater support bracket 60.In order to make the structure of fan more well-balanced, in the present embodiment, preferred driven unit 80 is arranged on the relative the other end in the one end with being provided with motor 30 of housing 1.Driven unit 80 comprises that the driving component 81 being fixedly connected with heater support bracket 60, the synchronous machine 82 being connected with driving component 81 and at least two are separately positioned on the sensitive switch 83,84 at slide rail 70 two ends.Driving component 81 comprise tooth bar 811 and with tooth bar 811 meshed gears 812, on tooth bar 811, be provided with through hole 8111, for heater support bracket 60 on outstanding locating column 62 combinations, thereby heater support bracket 60 is fixedly connected with tooth bar 811.Gear 812 is coaxially connected with the synchronous machine 82 being arranged on lower shell body 12, and preferred, synchronous machine 82 is fixed on the synchronous machine support 85 on lower shell body 12.Sensitive switch 83,84 are arranged on the two ends of slide rail 70, in order clearly to describe the problem, here two sensitive switches are expressed as respectively to the first sensitive switch 83 and the second sensitive switch 84, the first sensitive switch 83 is arranged on one end of the close exhaust outlet 40 of slide rail 70, and the second sensitive switch 84 is arranged on one end away from exhaust outlet 40 of slide rail 70.
Figure 5 shows that the structural representation of sensitive switch 83, introduce the working principle of sensitive switch below as an example of sensitive switch 83 example, the outer installment of sensitive switch 83 has an actuation button 831, in the time that external world's shake-up presses the button 831, spring 832 is compressed, and shell fragment 837 moves down, movable contact 833 engages with stationary contact 834, COM end 835 is held 836 circuit turn-ons with NO, and COM end 835 holds 836 to be connected with control circuit with NO, thus by control circuit by the supply disconnecton of synchronous machine 82; In the time of release button, spring 832 recovers original state under its elastic restoring force effect, and movable contact 833 departs from stationary contact 834, and COM end 835 holds 836 circuit to disconnect with NO, thereby synchronous machine is resumed work.
The button 831 of the first sensitive switch 83 and the button of the second sensitive switch 84 are separately positioned on the face in the face of heater support bracket 60, to contact with heater support bracket 60 butts.
Specifically introduce both cooling and heating fan and go out respectively the process of cold wind and warm braw below in conjunction with Fig. 6 (a), Fig. 6 (b), Fig. 7 (a), Fig. 7 (b).
Fig. 6 (a) is depicted as in the present embodiment status architecture schematic diagram when both cooling and heating fan goes out cold wind, and Fig. 6 (b) is depicted as the sectional view of Fig. 6 (a).In the time that user selects cold wind, synchronous machine 82 switches on power, driven gear 812 rotates, when rotating, gear 812 drive the tooth bar 811 being engaged with to move horizontally, specifically, tooth bar 811 is along moving away from the direction of exhaust outlet 40, because heater support bracket 60 is fixedly connected with tooth bar 811, therefore, moving horizontally of tooth bar 811 can drive heater support bracket 60 along moving away from the direction of exhaust outlet 40, until heater support bracket 60 contacts with the second sensitive switch 84 butts, touch the button of the second sensitive switch 84, touching the second sensitive switch 84 moves, synchronous machine 82 quits work, now, heater support bracket 60 shifts out the position relative with exhaust outlet 40, depart from exhaust outlet 40, as shown in Fig. 6 (b), the wind that wind drum 20 blows out is without heater 50, but directly blow out from exhaust outlet 40 via air channel 10, therefore, what blow out is cold wind.
Fig. 7 (a) is depicted as in the present embodiment status architecture schematic diagram when both cooling and heating fan goes out warm braw, and Fig. 7 (b) is depicted as the sectional view of Fig. 7 (a).In the time that user selects warm braw, synchronous machine 82 switches on power, driven gear 812 is to direction rotation contrary when going out cold wind, when rotating, gear 812 drive the tooth bar 811 being engaged with to move horizontally round about, specifically, tooth bar 811 moves along the direction near exhaust outlet 40, because heater support bracket 60 is fixedly connected with tooth bar 811, therefore, moving horizontally of tooth bar 811 can drive heater support bracket 60 to move along the direction near exhaust outlet 40, until heater support bracket 60 contacts with the first sensitive switch 83 butts, touch the button 831 of the first sensitive switch 83, touching the first sensitive switch 83 moves, synchronous machine 82 quits work, now, heater support bracket 60 is positioned at the position relative with exhaust outlet 40 just, as shown in Fig. 7 (b), the wind that wind drum 20 blows out blows out from exhaust outlet 40 via heater 50 from air channel 10, therefore, what blow out is warm braw.
Visible, adopt synchronous machine 82 and coupling component 81 to control the movement of heater support bracket 60, and by the position of jogging switches measurement heater support bracket 60, control the operation of synchronous machine 82, the heater 50 that can make to be fixed on heater support bracket 60 is optionally positioned at the just position to exhaust outlet 40, in the time that fan goes out cold wind, heater 50 is away from just the position of exhaust outlet 40 being arranged, in the time that fan goes out warm braw, heater 50 just arranges the position of exhaust outlet 40, can realize with simple structure the object of the selectable blowing cold air of fan or warm braw, sensitive switch little by disconnected power, break-make is rapid, therefore quite sensitive to the control of synchronous machine, improve the usability of both cooling and heating fan, thereby having solved in prior art heating blowing dual purpose fan complex structure causes assembling loaded down with trivial details and controls and unstablely cause function to be switched having some setbacks or downright bad technical problem.
It will be understood by those skilled in the art that the embodiment who these are only the utility model optimum, can be improved according to the above description or convert, for example, above-mentioned driving component be defined as the form of gear and tooth bar, can replace with worm and worm wheel.Do not making the improvement of making under the prerequisite of creative work and converting the protection domain that all should belong to the utility model claims.
