Description

Smoke exhaust ventilator with low level air inlet

Technical field

The utility model belongs to household smoke exhaust ventilator, is particularly provided with the smoke exhaust ventilator that can more approach the additional inlet duct of frying pan.

Background technology

The suspension height of existing Household hanging smoke exhaust ventilator at least will be higher than people's head, hang highly about 1.8～1.9 meters, but general 1.1～1.3 meters of the height of frying pan, cause the air inlet of smoke exhaust ventilator and the distance of frying pan to have 0.5～0.8 meter, this distance of 0.5～0.8 meter makes the oil smoke rising in its pot have many can not entering among hanging type smoke exhaust ventilator, pollutes air in kitchen.

Summary of the invention

The purpose of this utility model is to provide the smoke exhaust ventilator that more pumps oil smoke in frying pan.

Structure of the present utility model is:

Smoke exhaust ventilator with low level air inlet, comprise main inlet box shell 1, main inlet box shell 1 has below panel 2, it is characterized in that: on the panel 2 of below, have main tank

air admission hole

3,3 square centimeters of the minimal faces of main tank air admission hole 3, the maximum area of main tank air admission hole 3 is equal or approach the area of below panel 2; The below of below panel 2 is connected with an additional inlet duct 4, with on the main inlet box shell 1 additional inlet duct 4 top side plates 5 that below panel 2 is connected, have attachment device venthole 6, size, the shape of attachment device venthole 6 and main tank air admission hole 3 are identical and position is corresponding.

Additional inlet duct 4 is for below main inlet box shell 1, and to there being the place of pot to extend, the distance of shortening and oil smoke, more sucks oil smoke.Because the main inlet box shell 1 that tilts to install can not be installed to the position that approaches pot, if main inlet box shell 1 is installed to the position that approaches pot, the cooking of can not cooking operation.With additional inlet duct 4, can extend to the position that approaches pot, not draw again and ring the cooking operation of cooking.

Size, the shape of attachment device venthole 6 and main tank air admission hole 3 are identical and position is corresponding, make its oil smoke that enters additional inlet duct 4 from additional air admission hole 9 through attachment device venthole 6 and main tank air admission hole 3, and enter in main inlet box shell 1, oil smoke is extracted out.

On the additional air admission hole 9 of additional inlet duct 4, be covered with the back and forth barge board 10 of activity.General cooking stove has two duration and degree of heatings, but normal only with a duration and degree of heating cooking, only has a duration and degree of heating to produce oil smoke.For concentrating wind-force smoke pumping, with barge board 10, be fastened on the additional air admission hole 9 of additional inlet duct 4, with the reciprocal movable function of barge board 10, a part for additional air admission hole 9 being blocked can not air intake, and additional air admission hole 9 parts that are not blocked have larger smoke pumping wind-force, can make full use of exhausting power like this and obtain better smoke pumping effect.

Additional inlet duct 4 can have various ways with being connected of main inlet box shell 1, as the connection conveniently discharging with screw nut, or is directly welded and fixed, or connects with a plate.This piece plate connected mode be this piece connecting plate as the postnotum of main inlet box shell 1, also, as the postnotum of additional inlet duct 4, the advantage of this structure is additional inlet duct 4 and main inlet box shell 1 stable connection.

Also having a kind of technical scheme that can arbitrarily extend additional inlet duct 4 positions, is exactly to connect main inlet box shell 1 and additional inlet duct 4 with additional escape pipe 11.Concrete structure is: on the attachment device venthole 6 of additional inlet duct 4, be connected with additional escape pipe 11, additional escape pipe 11 extend into the inside of main inlet box shell 1.With connector, main inlet box shell 1 is connected with additional inlet duct 4, also can connects main inlet box shell 1 and additional inlet duct 4 with additional escape pipe 11.In order not allowing, to enter the parts in the main inlet box shell 1 of fume pollution of main inlet box shell 1, the additional escape pipe 11 of additional inlet duct 4 can also to be extend into the position, main inlet box gas outlet in main inlet box shell 1.Make the oil smoke that derives from additional inlet duct 4 directly enter the main inlet box gas outlet in main inlet box shell 1, directly discharged.

The sheet shaped substrate can also the portion of setting a trap on additional air admission hole 9 keeping out the wind, as:

The additional air inlet face 8 of additional inlet duct 4 is provided with additional air admission hole 9, on additional air admission hole 9, is also provided with barge board 10.

The additional air inlet face 8 of additional inlet duct 4 is provided with additional air admission hole 9, on additional air admission hole 9, is also provided with grid plate.

Advantage of the present utility model: the additional air admission hole 9 of additional inlet duct is below smoke pumping owner inlet box shell, position that can 0.01～0.20 meter apart from frying pan, the suspension height that just can guarantee smoke exhaust ventilator can be at 1.80～1.90 meters, do not affect people's cooking operation, can make again to only have the position of 0.01～0.20 meter to have lampblack-pumped suction opeing apart from frying pan, greatly reduce fume pollution air in kitchen.Deep bead on additional air inlet can make full use of exhausting power and obtain better smoke pumping effect.
