Abstract

Disclosed is an active dustproof ventilation window screen which is characterized in that a plurality of small fans are mounted on the upper and lower parts of a main window frame, an air isolation board is covered between the upper fan group and the lower fan group, a high-density dustproof screen is inserted in the outdoor side, the outdoor air is fed to indoor space or exhausted to outdoor space through the channel between the air isolation board and the dustproof screen under the effect of the small fan groups; thereby, the indoor air quality is improved.

Description

The active ventilation formula screen window that prevents dust

Affiliated technical field

The utility model relates to a kind of screen window that is installed on the dwelling house window, a kind ofly installs the dustproof screen window that small fan carries out active ventilation additional.

Background technology

The structure of present known screen window is to add the stainless steel gauze by window frame to make, the indoor side of leaning on the glass window of building is installed, when opening glass window, because outside air flows, can play the certain ventilation and the purpose of mosquito-insect-proof, when still using, because the screen window emptying aperture is bigger in the bigger area of a lot of dusts, unavoidablely to bring a large amount of dusts into, if but the too thin too close ability of ventilation that can make again that gauze is done reduces greatly.

Summary of the invention

Can not active ventilation in order to overcome existing screen window, and the effective deficiency that can not well take a breath simultaneously of dustproof, the utility model provides a kind of screen window, this screen window can be taken a breath for indoor simultaneously in a large number at effective dustproof, improve IAQ (indoor air quality), satisfy the relatively poor regional instructions for use of some air qualities.

The technical scheme that its technical problem that solves the utility model adopts is: respectively install several (deciding on the screen window size) general 15 cm widths in the top and the bottom of screen window frame additional one centimetre of a thickness is installed, length and width are 10 centimetres of 10 centimetres of *), be similar to the sort of small-sized fans of fan on the computer CPU radiator, leaning on up and down between the fan of an indoor side, use the acrylic plate isolation room inner air and outer air of whole piece 3 millimeter, by an outdoor side use two washable, be similar to the fine and close high efficiency particulate air of air-conditioning filter net or air filtration cotton (air quality on environment for use is decided) and so on, provide passage in the space that stays 1 centimetre in the middle of indoor-outdoor air division board and the screen pack for the air after filtering, effect by fan blows to the air after filtering indoor then, plays the purpose to indoor air-changing

The utility model has the advantages that, can also effectively prevent that outdoor dust from bringing into indoor when carrying out a large amount of ventilation indoor.

Description of drawings

Below in conjunction with 2 pages of drawings and Examples the utility model is further specified

Fig. 1 is: the master window frame that this use is novel; (adopting aluminium alloys, stainless steel to make)

Fig. 2 is: small-sized fans group in parallel; (employing is similar to the small-sized fans of computer CPU radiator fan, and 1 centimetre of length and width of thickness are 10 centimetres of 10 centimetres of *)

Fig. 3 is: the indoor-outdoor air division board of band fan exhaust vent (adopting organic plates or acryl to make)

Fig. 4 is: anti-dust filter mesh: adopt to be similar to air-conditioning filter net, perhaps air filtration is cotton makes)

Fig. 5 is: sectional side view of the present utility model

Fig. 6 is: be the air flow schematic diagram when the indoor air-changing

Fig. 7 is: electrical schematic

Among Fig. 1: 1. be that master window frame 2. is the filter screen slot for blower tray 6.

1. is that master window frame 3. air insulated plates 4. are small-sized fans 5. high-density air screen packs among Fig. 5

7. is power switch among Fig. 7,8. is that voltage-selected switch 9. is the fan forward-reverse switch

The specific embodiment

(Fig. 2) up and down the fan group be installed on respectively on the blower tray of top and the bottom of (Fig. 1) Main form, coat behind a small amount of fluid sealant (Fig. 3) indoor-outdoor air from plate in the place that needs on the master window frame to contact with division board again, be installed in above the master window frame, again (Fig. 4) screen pack inserted in (figure one) master window frame (6) the filter screen slot at last; The screen window main body installs.

Again (Fig. 7) external transformer output voltage is sent into (Fig. 2) fan group in parallel by the electrical equipment plug receptacle, select toggle switch (8) can change the speed of fan by the voltage on the external transformer (Fig. 7), electric power polarity conversion knob (9) can be selected to indoor air-supply or to outdoor exhaust.

Claims

1. the dustproof screen window of active ventilation formula, be installed on the dustproof screen window of active ventilation formula on the dwelling house window, two parts up and down at its master window frame are respectively installed many small-sized fanses, covering the air insulated plate between the fan up and down again, by an outdoor side high-density air screen pack is installed, is it is characterized in that, many small-sized fanses respectively are installed at two parts up and down of master window frame, covering the air insulated plate between the fan up and down by an indoor side, washable high-density air screen pack is being installed by an outdoor side.
