Abstract
The utility model relates to a device for preventing air return and back flow of a kitchen ventilator. The utility model is provided with a wind outlet which can freely rotate for 360 DEG and is provided with a filter on the top end of a common flue, and is provided with a wind direction device on the upper surface of the wind outlet. The upper part of the common flue is provided with an air pressure tester and a frequency changing fan which is connected with the air pressure tester. The device of the utility model has good wind guiding performance, and can effectively prevent the air return and the back flow of the kitchen ventilator.
Description
Technical field
The utility model relates to a kind of device that prevents return air, is specifically related to a kind of device that prevents that range hood return air from pouring in down a chimney.
Background technology
Along with the fast development of urban construction, newly-built high level is more and more, and the flue outlet in kitchen and exhaust-gas treatment are very big difficult problems.Usually all have public flue in the high building, in the gas outlet of each household the anti-air-return device is housed all, but often effect is undesirable.Many families are arranged at present in order to prevent that the return air of waste gas pours in down a chimney in the flue, often punch to exterior wall and public aisle, the discharging flue gas has had a strong impact on outward appearance and has polluted environment.
Summary of the invention
The purpose of this utility model is public flue is reasonably designed, and a kind of good wind-guiding performance that has is provided, and prevents the device that range hood return air pours in down a chimney.
The disclosed device that prevents that range hood return air from pouring in down a chimney of the utility model is to install one can 360 ° to rotate freely on the top of public flue, has the air outlet of filter, and weathercock is housed on air outlet; The frequency conversion fan that the air pressure tester is housed and is attached thereto on the top of public flue.After the flowed fluctuation of air pressure tester gas in testing flue, signal is transferred to frequency conversion fan, in time adjusts the rotating speed of frequency conversion fan, the gas in the flue is upwards discharged rapidly.Weathercock on the air outlet is by the wind of impression from different directions, and the air-out direction that adjusts the air port is identical with wind direction all the time, avoids return air to pour in down a chimney; The filter that is installed in air outlet simultaneously can filter waste gas, reduces the pollution of waste gas to atmosphere.
Below, in conjunction with the accompanying drawings and embodiments the device that the utility model proposes is further described.
Description of drawings
Fig. 1 prevents range hood return air flowing backward device schematic diagram.
The specific embodiment
As shown in Figure 1, wherein 1 is weathercock, and 2 is rotatable air port, and 3 is filter, and 4 is frequency conversion fan, and 5 is the air pressure tester, and 6 is louver type baffle, and 7 is the lampblack absorber air outlet, and A is a wind direction, and B is the user, and C is public flue.
The frequency conversion fan 4 that the utility model is equipped with air pressure tester 5 and is attached thereto on the top of public flue C.After air pressure tester 5 is being tested the flowed fluctuation of gas in the flue, signal is transferred to frequency conversion fan 4, intelligence is adjusted the rotating speed of frequency conversion fan, and the gas in the flue is upwards discharged rapidly.Be equipped with one on the top of public flue and can 360 ° rotate freely, have the air outlet 2 of filter 3, weathercock 1 is housed on air outlet 2; Weathercock 1 is by the wind of impression from different directions, and the air-out direction that adjusts the air port is identical with wind direction all the time, avoids return air to pour in down a chimney; The filter 3 that is installed in air outlet simultaneously can filter waste gas, reduces the pollution of waste gas to atmosphere.
