Abstract
The utility model discloses a naturally ventilating window which is installed at the ventilating port of the inner wall of a toilet or a kitchen. One rotating blade of the inner side of the naturally ventilating window is connected with a support frame by a shaft. The rotating blade whose length and width are all greater than the length and the width of the ventilating window is a flat sheet, and is made of light plastic. The rotating blade can be opened by a weak air flow. When back flow air appears on the inner wall, the rotating blade is closed, and the air flow can not pass. And when back flow air do not appear on the inner wall, the rotating blade can be opened by the negative pressure of the inner wall; the indoor air flow can be discharged form one air channel of the inner wall; thereby, the existence of circulation air can be ensured indoors frequently.
Description
The utility model is a kind of device that is installed in the interior wall ventilation opening of residential building kitchen or washroom, and it can prevent from can open by natural wind again in the downdraught inlet chamber, and indoor air flow is under normal circumstances discharged to the interior wall air channel from vent window.
At present, a kind of " the toilet ventilation device " that some residents use is to rotate with the motor impeller, mandatoryly indoor gas is entered the interior wall air channel and reaches the purpose of ventilation.The no preventing air reverse flow valve block of this type of device that has, it is indoor to still have a small amount of downdraught to flow into after the shutdown, on the contrary " ventilator " that the preventing air reverse flow valve block is arranged that have, valve block is closed condition after shutdown, and air can not flow.Like this, indoorly still can not obtain desirable hygienic conditions.In addition, this type of " ventilator " starts the back power consumption and with noise, foreign flavor indoors should in time be shut down after discharging, and can increase power consumption if forget shutdown, and this can cause some inconvenience to the user.
The purpose of this utility model provides a kind of device, and it need not electricity consumption, can stop the downdraught in interior wall air channel, can open by the interior wall negative pressure again, indoor air flow is discharged from the interior wall air channel, thereby the air that guarantees washroom or kitchen is fresh.
The purpose of this utility model is achieved in that in rectangle ventilation window inboard the axle that rotating vane is made by thin wire links with support.Rotating vane is that length and width are all greater than the rectangular sheet of ventilation window.It is made by light plastics, and is sagging because of action of gravity when static; Air-flow is when indoor pouring in down a chimney, and rotating vane is subjected to air-flow thrust to rotate and blocked by window frame to indoor direction, rotating vane and window frame plane closure, make air-flow can not inlet chamber in; When no downdraught, it is the center Unscrew with the axle that the negative pressure in interior wall air channel makes rotating vane, and indoor air flow can be discharged by window.Because adopt such scheme, faint air-flow also can make rotating vane open, discharge via the interior wall air channel, the downdraught in interior wall air channel then can not inlet chamber in, therefore need not both can make the indoor moving air in a small amount that often has, maintenance indoor cleaning with the device of power consumption.
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is a front view of the present utility model.
Fig. 2 is the A-A sectional drawing of Fig. 1.
Fig. 3 is the longitudinal plan of first embodiment.
Fig. 4 is the longitudinal plan of second embodiment.
Among the figure, 1, ventilation window 2, rotating vane 3, axle 4, support 5, window frame 6, interior wall
In the embodiment shown in fig. 3, air-flow flows out from the interior wall air channel, and rotating vane is closed.
In the embodiment shown in fig. 4, air-flow is from indoor outflow, and rotating vane is opened.
Claims (2)
1, a kind of window has rotating vane in the ventilation window installed inside, it is characterized in that rotating vane links with support by the axle made from thin wire, and rotating vane is that length and width are all greater than the rectangular sheet of ventilation window, when it is closed and the plane closure of window frame.
2,, it is characterized in that rotating vane adopts light plastics to make according to the described natural ventilation window of claim 1.
