Description
Technical field
The utility model is about heating and ventilating fan, particularly about the heating ventilation being installed on windowFan.
Background technology
Fig. 1 is known technology schematic diagram.
As shown in Figure 1, known heating and ventilating fan body 1, comprising: framework 2, be positioned at described frameIn frame 2, be provided with hodmadod 3 and the wind path switch boards 4 of flabellum 8, motor 9. In described body 1Have from hodmadod air outlet 5 to be arranged at hodmadod air outlet 5 framework 2 sidewalls in opposite directionsThe wind path of outdoor air outlet 6 and from hodmadod air outlet 5 to the indoor air-out that is arranged at face shield 60The wind path of mouth 7.
Wind path switch boards 4 is outside outstanding circular arc, by be positioned at framework 2, hodmadod goes outIn space between air port 5, outdoor air outlet 6 and indoor air outlet 7, rotate, and realization heating,Ventilation and functions/drying.
Because framework 2 is interior, the space that wind path switch boards 4 is rotated need to be set, so framework 2 entiretyGreatly. And limit by framework 2 inner spaces, sometimes wind path switch boards 4 is had to arrange smallerly,The outdoor air outlet 6 being hidden by wind path switch boards 4 so just correspondingly needs to arrange smallerly, leadsCausing air quantity reduces.
Utility model content
The purpose of this utility model is to provide a kind of heating and ventilating fan, realizes body miniaturization.
For achieving the above object, a kind of heating and ventilating fan of the present utility model, comprising: framework, be provided withThe hodmadod of flabellum and motor, be located at wind path switch boards and the face shield at hodmadod air outlet place, described frameThe sidewall of frame is provided with and the outdoor outdoor air outlet being communicated with, and described face shield is provided with indoor air inlet and chamberInterior air outlet, is provided with heater, described wind path between described wind path switch boards and described indoor air outletWhen switch boards is rotated, a part for described wind path switch boards turns to framework through described outdoor air outletOutside.
The utility model has the advantage of, when realizing body miniaturization, prevent that air quantity from reducing.

Detailed description of the invention
Fig. 2 is cross-sectional schematic under the heating pattern of the utility model embodiment, and Fig. 3 is that this practicality is newCross-sectional schematic under the ventilatory pattern of type embodiment, Fig. 4 is the drying mode of the utility model embodimentLower cross-sectional schematic.
As shown in Figure 2, Figure 3, Figure 4, the heating and ventilating fan 10 of the utility model embodiment, itsBody 100 comprises: framework 11, be provided with flabellum 21 and motor 22 hodmadod 20, be located at hodmadodThe wind path switch boards 30 at air outlet 23 places and face shield 40, the sidewall of framework 11 is provided with outdoor and is communicated withOutdoor air outlet 12, face shield 40 is provided with indoor air inlet 41 and indoor air outlet 42, wind pathBetween switch boards 30 and indoor air outlet 42, be provided with heater 50, when wind path switch boards 30 is rotated,A part for wind path switch boards 30 turns to framework 11 outsides through outdoor air outlet 12.
Again as shown in Figure 2, in the time that heating and ventilating fan 10 is heating pattern, wind path switch boards 30 is blockedLive outdoor air outlet 12, room air enters hodmadod 20 from the indoor air inlet 41 of face shield 40In, sucked rear pressurization by flabellum 21 and blow out and contact wind path switch boards 30, along wind path switch boards 30Enter heater 50, after being heated by heater 50, blow to chamber by the indoor air outlet 42 of face shield 40In.
In addition, wind path switch boards 30 is provided with outwards outstanding arc-shaped curved surface 31, this arc-shaped curved surface 31In the time that wind path switch boards 30 covers in outdoor air outlet 12 completely, be from hodmadod air outlet 23 sidesTo the shape of outdoor air outlet 12 lateral bends. In the time that heating and ventilating fan 10 is heating pattern, wind path is cutChange plate 30 and cover in outdoor air outlet 12, room air enters from the indoor air inlet 41 of face shield 40Hodmadod 20 is pressurized, from hodmadod air outlet 23 blows out, collides wind path switch boards 30Arc-shaped curved surface 31, flows to heater 50 swimmingly along arc-shaped curved surface 31. Reduce wind path switch boards 30To the resistance of Air Flow, reduce air loss, prevent that air quantity from declining, and reduces noise.
Again as shown in Figure 3, in the time that heating and ventilating fan 10 is ventilatory pattern, wind path switch boards 30 is to chamberInterior air outlet 42 sides are rotated, and a part for wind path switch boards 30 is passed outdoor air-out in rotation processMouth 12 protrudes from the outside of framework 11 sidewalls. Turn to air outlet 42 in complete covered chamber, a partWind path switch boards 30 covered chamber in air outlet 42, a part wind path switch boards 30 be positioned at framework11 outsides. That is to say, a part for the wind path switch boards 30 of rotation is to the space of framework 11 outsidesOutstanding. Be positioned at like this space that framework 11 rotates for wind path switch boards 30 and can arrange littlely,Thereby the size of body 100 can be reduced.
Again as shown in Figure 4, in the time that heating and ventilating fan 10 is drying mode, wind path switch boards 30 is to chamberInterior air outlet 42 sides are rotated, and the state while not turning to ventilatory pattern switches but be opened to wind pathBetween the upper end of plate 30 and outdoor air outlet 12, there is the degree in space. One of wind path switch boards 30Part protrudes from the outside of framework 11 sidewalls in rotation process through outdoor air outlet 12, turn toWhile covering in the indoor air outlet 42 of a part and the outdoor air outlet 12 of a part, heating is changed simultaneouslyGas fan 10 adds hot-air in ventilation.
And a part protrudes from framework 11 sidewalls while rotation due to wind path switch boards 30, so even if increaseAdd the area of wind path switch boards 30, also can guarantee to have sufficient space turning for wind path switch boards 30Moving. Ventilation or when drying mode like this, outdoor air outlet 12 areas that hidden by wind path switch boards 30Can correspondingly increase, even if dwindle the size of body 100, also can prevent that air quantity from reducing.
Again as shown in Figure 2, in the time that wind path switch boards 30 covers in outdoor air outlet 12 completely, wind pathSwitch boards 30 is positioned at framework 11 inside completely. Although heating and ventilating fan 10 is in dry and ventilatory patternUnder, a part for wind path switch boards 30 protrudes from framework 11 outsides, but heating and ventilating fan 10 is notWhen operation, state when wind path switch boards 30 is positioned at heating pattern, wind path switch boards 30 hides completelyCover outdoor air outlet 12, do not protrude from framework 11 sidewalls, be positioned at framework 11 inside completely. Prevent because ofCause body 100 volumes to increase for wind path switch boards 30 protrudes from framework 11 outsides, cannot pass throughWindow opening. Prevent from cannot being installed to window because wind path switch boards 30 causes heating and ventilating fan 10Deng on.
Again as shown in Figures 2 to 4, at hodmadod air outlet 23, more close than wind path switch boards 30The place of flabellum 21 sides is provided with grid 13.
Heating and ventilating fan 10 is ventilation or drying mode, and wind path switch boards 30 does not have outside complete covered chamberWhen air outlet 12, after touching grid 13, can not insert in hodmadod air outlet 23 on finger. PreventFinger puts in and in the flabellum 21 of hodmadod 20, causes injuredly, improves security.
