Described deep bead is positioned at the side wall side of bracing frame, and is located on the long limit away from first pressure fan and second pressure fan of the 3rd regional opening.
Described heater is made up of the semiconductive ceramic sheet and the athermic ceramic insulator sheet of heating, and above-mentioned ceramic insulator sheet is arranged on the minor face of the 3rd regional opening, by first pusher side of blowing.
Deep bead is arranged on the first pressure fan end that leans in described the 3rd zone.
Described deep bead exceeds rotating shaft the extending by the second pressure fan end in exhaust outlet projection line position and to the 3rd zone of first pressure fan.
Peristome in described the 3rd zone is provided with catch net, and this catch net is made up of the network structure and the nonventilated blind plate that ventilate, and blind plate is arranged on the first air-supply pusher side, and the shorter direction of the opening in the 3rd zone forms deep bead.
Advantage of the present utility model is, by suppress by first pressure fan produce by boasting along the quick flow air of sidewall, the wind after making wind speed stable passes heater, gives full play to the thermal effect that adds of heater, and makes opening integral body blow out uniform wind.

The specific embodiment
As shown in Figure 2, be the utility model first embodiment schematic diagram.The heating and ventilating fan 100 that the bathroom is used, comprise the framework 110 that does not form the casing shape, when framework 110 is provided with heating and ventilating fan, be provided with opening 111 at the face that becomes its underpart, frame openings portion is provided with the face shield 200 of taking air port 210 and inlet scoop 220 out of, and framework 110 is divided into three big zones: first area 300, second area 400, the 3rd zone 500.Be provided with first pressure fan 310 in the first area 300, be provided with in the second area 400 the ptc heater combination of being made up of several ptc heaters 511 and bracing frame 512 510 is installed in second pressure fan, 410, the three zones 500, and be provided with exhaust outlet 520.First area 300 disposes side by side with second area 400, three zone 500 adjacent with first area 300 and second area 400 is positioned at the long limit of framework, one end in the 3rd zone 500 is communicated with the first area, and the rotating shaft (not shown) of first pressure fan 310 is consistent with the direction of the depth in the 3rd zone 500.On side wall side, be provided with deep bead 530, be used to adjust wind speed through this heater air away from the bracing frame on the long limit of first pressure fan and second pressure fan.By blocking wind speed part faster with deep bead 530, make air dispersion, thereby can blow out impartial air at this place.Pass heater by the wind after making wind speed stable, give full play to the thermal effect that adds of heater.
For ease of describing the present invention, the front portion of ptc heater 511 is divided into two parts, definition is a part by first pressure fan, 310 sides, definition is the b part by second pressure fan, 410 sides.
As shown in Figure 3, be the utility model second embodiment schematic diagram.Be with the difference of first embodiment, deep bead 530 be located at the 3rd zone 500 by first pressure fan, 310 ends, i.e. a part of exhaust outlet (not shown).
The air that first pressure fan 310 blows out partly blows out from a, runs into the sidewall on opposite, when resisting little b part along the above-mentioned sidewall flow direction, also blows out the little air that the air ratio b that partly produces by boasting from a partly produces by boasting from the air outlet (not shown).So,, can make air concentrate on ptc heater 511, and can make the air thermally equivalent by blocking the few a part of blow out air.
As shown in Figure 4, be the schematic diagram of the 3rd embodiment.Be that with the difference of second embodiment deep bead 530 is bigger, the rotating shaft 311 that exceeds first pressure fan 310 extends at second pressure fan, 410 ends that lean on of the position of exhaust outlet (not shown) projection line 521 to the 3rd zone 500, promptly partly is provided with to b.That is to say, as shown in Figure 4, deep bead 530 is to exceed the centre line C L that the C-C direction with framework 110 sides of extending from rotating shaft 311 parallels, along the D-D direction of the length direction in the 3rd zone 500, exceed above-mentioned projection line 521, to partly holding setting with the adjacent b of second area 400.Above-mentioned projection line 521 be arranged in parallel from exhaust outlet and above-mentioned centre line C L.So, can make the air that passes the ptc heater 511 that is arranged on peristome more even.Particularly deep bead 530 makes more air flow to the b part, thereby makes by the wind of ptc heater 511 more even to second area 400 end settings.And, can block the noise that sends by first pressure fan 310, promptly as shown in Figure 2, noise is difficult to from air outlet 210 more to indoor transmission.
As shown in Figure 5, be the schematic diagram of the 4th embodiment.Be provided with catch net 540 between the exhaust outlet (not shown) in the 3rd zone 500 and ptc heater (not shown), this catch net 540 is made up of the network structure 532 and the nonventilated blind plate 531 that ventilate.Blind plate 531 is arranged on the outside of corresponding ptc heater a part, forms deep bead.Blow out the few a part of air quantity owing to blocking, make the air that passes through the ptc heater (not shown) that is arranged on peristome even with blind plate 531.
