As shown in the FIG., a kind of heating and ventilating fan 100 of the present utility model, comprise body 1, be arranged on described body 1 inside two spiral helicine hodmadods 2, be located at respectively the described hodmadod 2 interior left and right sides ventilation pressure fan 3 and circulation pressure fan 4, be located at described circulation pressure fan 4 air outlet 40 places heater 5, be located on described body 1, make described ventilation pressure fan 3 air outlets 30 and outdoor connection exhaust outlet 6, be located at body openings 10 below of described body 1 and cover the face shield 7 of described body openings 10, veiled air inlet 70; On described body 1, be also provided with a plurality of the first air outlets 11,12,13, described the first air outlet 11,12,13 and described heater 5 arrange in opposite directions, and described the first air outlet 11,12,13 respectively by pipeline be arranged on bathroom in the second air outlet 21,22,23 of zones of different be communicated with.
Arranging according to user's actual needs of a plurality of the second air outlets 21,22,23, can be arranged at respectively lavatory, the region such as the district of washing one's hands, the district of undressing, shower district, when shower district also comprises shower area and baths district, can also in shower area and the district that baths, second air outlet 21,22 be respectively set.
The opening and closing device 71 of controlling face shield air inlet 70 openings of sizes can also be provided with at described face shield air inlet 70 places, by opening or closing the opening and closing device 71 at face shield air inlet 70 places, the intake size of face shield air inlet 70 can be regulated.
Refer to again circulation pattern as shown in Figure 1.When heating and ventilating fan 100 is when warming oneself pattern, user first carries out preheating before using bathroom, and according to user's selection, the opening and closing device 71 at face shield air inlet 70 places makes face shield air inlet 70 open or open certain limit completely, for sucking the air in bathroom.Circulation pressure fan 8 and heater 5 operations, ventilation pressure fan 3 does not move, and the air in bathroom enters body 1 inside by face shield air inlet 70, then through heater 5, becomes heated airflow to a plurality of the first air outlets 11,12,13.Due to the first air outlet 11,12,13 respectively by pipeline be distributed in bathroom in the second air outlet 21,22,23 of zones of different (as shower area, the district that baths, the district etc. of undressing) be communicated with, so warm braw can, along Flows to the second air outlet 21,22,23 places that are positioned at bathroom zones of different, flow in the zones of different in bathroom by each second air outlet 21,22,23.That is to say, when heating pattern, the first air outlet 11,12,13 and the second air outlet 21,22,23 are used for discharging warm braw as warm braw air outlet.
In order to improve heating effect, can also be connected the first air outlet 11,12,13 and the second air outlet 21,22,23 with heat-barrier material with the good metallic conduit of thermal conductivity, thermal loss when minimizing air flows in pipeline.
In addition, in general, the middle part of heater 5 is that in the middle of whole heater 5, temperature is the highest, therefore can select first air outlet 12 at corresponding heater 5 middle parts to connect from body 1 the second air outlet 22 farthest, guarantees that warm braw still has higher temperature when the second air outlet 22 blows out.
Even if bathroom area is larger like this, warm braw still can be sent to the zones of different in whole bathroom, eliminates the cold sense of discomfort producing when user enters bathroom.
Refer to again ventilatory pattern as shown in Figure 2.When heating and ventilating fan 100 is during in ventilatory pattern, 3 operations of ventilation pressure fan, circulation pressure fan 4 and heater 5 do not move.Due to the first air outlet 11,12,13 on body 1 respectively by pipeline be distributed in bathroom in the second air outlet 21,22,23 of zones of different be communicated with, so the air in bathroom, except entering body 1 inside by face shield air inlet 70, can also enter body 1 inside by the second air outlet 21,22,23.That is to say, when ventilatory pattern, the first air outlet 11,12,13 and the second air outlet 21,22,23 are used for sucking bath room air as indoor air inlet.
Again because connect by pipeline between the second air outlet 21,22,23 and the first air outlet 11,12,13, the parts obstruct such as having heaters 5 between ventilation pressure fan 3 and the first air outlet 11,12,13, the resistance that air in bathroom is sucked by ventilation pressure fans 3 from the second air outlet 21,22,23 is larger, so enter by the second air outlet 21,22,23 air that the air ratio of body 1 inside enters body 1 inside by face shield air inlet 70, wants much less.
Therefore, in the time need to making body 1 below and position around thereof take a breath fast, can face shield air inlet 70 be opened completely by opening and closing device 71, when take a breath fast in other region of needs, can make face shield air inlet 70 close or close certain limit completely by opening and closing device 71, thereby increase the intake of the second air outlet 21,22,23 of each location in bathroom.Take a breath fast in the part that can realize large area bathroom like this.
Refer to again drying mode as shown in Figure 3.When heating and ventilating fan 100 is during in drying mode, ventilation pressure fan 3 and circulation pressure fan 4, heater 5 move simultaneously.In order to ensure enough intakes, opening and closing device 71 on face shield 7 is opened completely, bathing room air enters behind body 1 inside by face shield air inlet 70, under the effect of ventilation pressure fan 3, the bath room air of a part is by outside exhaust outlet 6 discharge chambers on body 1, under the effect of circulation pressure fan 4, the room air of another part is heated and is passed through afterwards the first air outlet 11,12,13 and the second air outlet 21,22,23 discharged in bathroom by heater 5.That is to say, when drying mode, the first air outlet 11,12,13 and the second air outlet 21,22,23 are used for discharging warm braw as warm braw air outlet.Even if bathroom area is larger like this, warm braw still can be sent to the zones of different in whole bathroom fast, realizes the local rapid draing in large area bathroom.

Refer to again ventilatory pattern as shown in Figure 2.Described circulation pressure fan 4 can be for being comprised of axial flow flabellum and the motor that can positive and negative direction rotates.
The motor can positive and negative direction rotating that is to say that motor can (the first air outlet 11,12,13 sides) rotate also and can to outside, (exhaust outlet 6 sides of body 1) rotate to indoor.
Pass through said structure, when heating and ventilating fan 100 is during in ventilatory pattern, ventilation pressure fan 3 and circulation pressure fan 4 move simultaneously, because circulation pressure fan 4 is comprised of axial flow flabellum and the motor that can positive and negative direction rotates, so now circulate, pressure fan 4 can rotate with same direction (to body 1 exhaust outlet 6 sides) with ventilation pressure fan 3, jointly sucks room air and room air is drained into outdoor by the exhaust outlet 6 on body 1.
As mentioned before, heating and ventilating fan 100 is when ventilatory pattern, if circulation pressure fan 4 does not move, only has 3 operations of ventilation pressure fan, because the parts obstruct such as having heaters 5 between ventilation pressure fan 3 and the first air outlet 11,12,13, the resistance that air is sucked by ventilation pressure fans 3 from the second air outlet 21,22,23 is larger, so enter by the second air outlet 21,22,23 air that the air ratio of body 1 inside enters body 1 inside by face shield air inlet 70, wants much less.Therefore by make to take a breath pressure fan 3 and circulation pressure fan 4, play the effect that sucks room air simultaneously, can increase the intake of the second air outlet 21,22,23.Thus, guarantee the intake of the second air outlet 21,22,23, improve the effect of local ventilation.
Fig. 4 A is the schematic diagram of single the first air outlet of the present utility model.In the utility model, the first air outlet 11,12,13 can be all identical.Fig. 4 A be take the first air outlet 11 and is illustrated as example.As shown in Figure 4 A, the first air outlet 11 is provided with the opening and closing device 80 of controlling the first air outlet 11 openings of sizes.The present embodiment, by opening or closing the opening and closing device 80 at the first air outlet 11,12,13 places, can regulate by the air force of the first air outlet 11,12,13.
By said structure, no matter heating and ventilating fan 100 is under what pattern, and user can according to actual needs, optionally open or close the first air outlet 11,12,13 of a part.When in the first air outlet 11,12,13 one closes, such as the first air outlet 11 is closed, the second air outlet 21 of connection corresponding to this first air outlet 11 just cannot air intake or exhaust, and first air outlet 12,13 of another part is opened, the second air outlet 22,23 being communicated with this first air outlet 12,13 just can air intake or exhaust, thereby realizes optionally local heating or ventilation.That is when, part is used, increase ease of use.
Fig. 4 B is that a plurality of the first air outlet of the present utility model is arranged on the schematic diagram on body.As Fig. 4 A, shown in Fig. 4 B, described the first air outlet 11, 12, 13 places are respectively equipped with three joints 81, these three joints 81 respectively with described the second air outlet 21, 22, 23 connect by pipeline, on described joint 81 or a side be provided with stepper motor 90 (certainly, synchronous motor is also fine), described the first air outlet 11, 12, 13 opening and closing device 80 is for being located at the shutter 82 in described joint 81, described shutter 82 is by being connected with described stepper motor 90, the rotating shaft 83 that control shutter 82 rotates and one-body molded with this rotating shaft 83, the blade 84 that is positioned at these rotating shaft 83 both sides forms.
In the present embodiment, as long as stepper motor is set and stepper motor 90 is just connected with rotating shaft 83, can pass through the rotation of step motor control rotating shaft 83, this point is the known technology of the art, so do not repeat them here.
Because rotating shaft 83 is one-body molded with blade 84, so will be with moving vane 84 to rotate when rotating shaft 83 is rotated.When blade 84 turns to the wind path in joint 81 parallel (vertical with heater 5), the wind joint 81 of can flowing through swimmingly, is considered as shutter 82 and opens completely; When blade 84 turns to the wind path in joint 81 vertical (parallel with heater 5), wind is stopped by blade 84 joint 81 of can not flowing through, be considered as shutter 82 and close completely; When blade 84 turns to the interior wind path of joint 81 both not parallel also out of plumb, be considered as shutter 82 and not exclusively open, the wind of a part stopped by blade 84, and the wind of a part is by the sun gear joint 81 of can flowing through.By controlling the rotation of blade 84, just can control the switching of joint 81 interior wind paths like this, thereby regulate the air quantity of first air outlet 11,12,13 of flowing through.The switching of conveniently adjusted the first air outlet 11,12,13.
The tubular that described joint 81 surrounds for top wall 85, sidewall 86 and diapire 87, the two ends of described rotating shaft 83 are vertically set on respectively in the top wall 85 and underside wall 87 of described joint 81, and the interior setting of described joint 81 protrudes from the sealed muscle 88 of described joint 81 top wall 85, underside wall 87 and sidewall 86.
Generally, in order to ensure blade 84, can rotate swimmingly joint 81 is interior, between the top wall 85 in joint 81, sidewall 86 and diapire 87 and blade 84, need to leave certain gap.When user closes the first air outlet 11,12,13 completely, when blade 84 turns to the wind path in joint 81 vertical (parallel with heater 5), wind can leak out by causing from this gap like this.
