Detailed description of the invention
Referring to Fig. 1～Fig. 4, the detailed description of the invention of new blower fan described in the utility model is described in detail.
As shown in Figure 1 to 4, new blower fan is the box like parts in flat on the whole, and it has the shell being placed in outside, and this shell is made up of front and back panel, a up and down four block side plate, these six blocks of plates jointly surround one and load, for receiving, the chamber stating each parts.At two the corner fixing connectors 2 with mounting groove respectively up and down being positioned at rear side of epipleural 11 and lower side panel 12, this connector is made up of the parts of amounting to that two panels is vertically L-shaped.Shown in this utility model, new blower fan is tightened on passive bracing frame or surface of wall through the mounting groove on connector 2 by screw.
Left plate 13 offers the return air inlet 131 in communication chamber and air outlet 132, right plate 14 offers the air inlet 141 outside communication chamber and exhaust outlet 142.The described air inlet 141 of wind inlet channel two ends connection and the air outlet 132 of new blower interior, the internal described return air inlet 131 of wind output channel two ends connection and exhaust outlet 142.
A turbofan 3 of double-faced ventilated pair of air outlet it is provided with in new fan chamber, this turbofan 3 has two spiral cases being axially set up in parallel, it is coaxially disposed two impellers in two spiral cases, drive a motor of two wheel rotation, motor may be disposed in a spiral case therein, is connected by motor shaft and drives the impeller in two spiral cases.For making new blower fan structure more compact, turbofan in the present embodiment is axially perpendicular to front and back panel and arranges, the axial opposing setting of two air inlets of two spiral cases, one towards front panel 15, one towards rear board 16, two air outlets one are arranged towards the exhaust outlet 142 outside communication chamber, and one is arranged towards the air outlet 132 in communication chamber, and dividing plate by being parallel to front and back panel is split between two spiral cases so that two spiral cases be laid in respectively wind inlet channel with in wind output channel.In the present embodiment, turbofan 3 is arranged on the lower left quarter in chamber as shown in the figure, closer to return air inlet 131 place of indoor.
In new fan chamber, described air inlet 141, return air inlet 131 place are provided with heat exchanger 4, such as can adopt total-heat exchanger, two paths of heat exchanger 4 connect with wind output channel with wind inlet channel respectively, so that wind inlet channel carries out heat exchange with the gas of flowing in wind output channel.Heat exchanger 4 in the present embodiment is arranged on the upper left quarter in chamber as shown in the figure, closer to return air inlet 131 place of indoor.
Described wind inlet channel is constituted by the polylith dividing plate new fan chamber of segmentation with wind output channel, as it can be seen, each parts are divided into following a few part by dividing plate in new fan chamber: be positioned at air-inlet cavity and the air draft chamber of upper and lower position, right side, be positioned at the heat exchanger 4 of upper left quarter, be positioned at the turbofan 3 of double-faced ventilated pair of air outlet of lower left quarter.Wherein, air-inlet cavity connects with air inlet 141 and exhaust outlet 142 respectively with air draft chamber, air-inlet cavity is separated by a dividing plate 5 with air draft chamber, one communication air-inlet cavity of heat exchanger 4 and the air inlet towards rear board 16 of turbofan 3, turbofan 3 to should air inlet air outlet connection air outlet 132, another communication return air inlet 131 of heat exchanger 4 and the air inlet towards front panel 15 of turbofan 3, turbofan 3 is to should the air outlet connection air draft chamber of air inlet.Wherein, air filter 6 also can be set in air-inlet cavity, such as HAPE filter.
And, it is arranged on the described dividing plate 5 between air-inlet cavity and air draft chamber, it is provided with and can control the first air-valve 91 whether air-inlet cavity connects with air draft chamber, at described air inlet 141 and exhaust outlet 142 place, be provided with and control the second air-valve 92 and the 3rd air-valve 93 whether air inlet and exhaust outlet close.These three air-valve is driven linkage to arrange by a motor, so that second and third air-valve 92,93 open and-shut mode synchronizes, and contrary with the first air-valve 91 open and-shut mode, namely the first air-valve 91 open and-shut mode is contrary with second and third air-valve 92,93 open and-shut mode.As it can be seen, the employing slew page structure of air-valve described in the present embodiment, corresponding type of drive is: arrange a contiguous block on described motor shaft, and contiguous block arranges three eccentric connecting rods connected, and each connecting rod connects each slew page.
Pass through said structure, the control unit of blower fan (can be learnt by network according to the pollution level of outdoor air, or learnt by respective sensor), control described motor and drive above-mentioned air-valve action, thus, new blower fan is made to have two states: new wind changes wind state and indoor circulation state, is illustrated below:
New wind changes wind state: controls second and third air-valve 92,93 and opens, and first air-valve 91 close, now, air-inlet cavity and air draft chamber are spaced, described wind inlet channel does not connect mutually with wind output channel, under the driving of turbofan 3, outdoor new wind successively through air inlet 141, air-inlet cavity, heat exchanger 4, turbofan 3 towards in the air inlet and air outlet, air outlet 132 inlet chamber of rear board 16, room air through return air inlet 131, heat exchanger 4, turbofan 3 towards outside the air inlet and air outlet, air draft chamber, exhaust outlet 142 discharge chamber of front panel 15.
Indoor circulation state: control the first air-valve 91 and open, and second, three air-valves 92, 93 close, now, air inlet 141 and exhaust outlet 142 are closed, and air-inlet cavity is connected with air draft chamber, described wind output channel is connected with wind inlet channel, under the driving of turbofan 3, room air is through return air inlet 131, heat exchanger 4, turbofan 3 is towards the air inlet of front panel 15 and air outlet, air draft chamber, air-inlet cavity, heat exchanger 4, turbofan 3 is towards the air inlet of rear board 16 and air outlet, air outlet 132 returns to indoor, in this process, the filter 6 that the gas being returned can be laid in air channel is filtered.
Additionally, it is possible to motors different for the above-mentioned first, second and third each freedom of air-valve is independently driven, or second and third air-valve is driven by a motor linkage, the first air-valve is independently driven independent control by a motor.Further, above-described embodiment is to illustrate for two states of air-valve opening and closing, it can be appreciated that under special circumstances, it is possible to the air-valve that half-open or proportional opening is different.
The foregoing is only preferred embodiment of the present utility model; not in order to limit this utility model; above-mentioned up and down before and after all descriptions will make reference to are described; the use of the non-limiting present invention; all within spirit of the present utility model and principle; any amendment of being made, equivalent replacement, improvement etc., should be included within protection domain of the present utility model.
