Operation principle of the present invention is as follows:
Use patent of the present invention culinary art mist extractor waste gas, when decocting with digester (4) high cooking, or the slow fire that reaches a few hours is stewed slowly, or do not need personnel in pot, to stir-fry and other whens operation, operating personnel can turn off power supply, and smoke exhaust (7) quits work, dustproof blade (24) closure.Pull handle (43) downwards, the below of counterweight lifting transparent slip lid (6) and guide wheel A (40) perk, slip lid sealing strip (37) separates with slideway (16), guide wheel B (41) contacts with slideway (16) with last travelling wheel (35), continue to pull handle (43) downwards, counterweight lifting transparent slip lid (6) can be slided into the below downwards along slideway (16), make the stokehold neutral be transferred to less state.When counterweight lifting transparent slip lid (6) glides, to slide counterweight (39) by chain wheel rope B (38) and counterweight pulley (18) upwards promotes, simultaneously, the swing arm counterweight (31) that slip lid counterweight (39) drives its top upwards promotes, chain wheel rope A (30) is in relaxed state, swing arm (28) is being with magnet (26) to swing to the top from the below, because the effect of magnetic force, be subjected to magnetic spare (27) drive dustproof blade (24) along with magnet (26) by the closed condition swing of below open mode to the top, it is outdoor that oil flue waste gas is discharged to swimmingly.
When using frying pan (3) cooking or need in the less motion action in the kitchen range top (1) top, can handle blower fan draws gauge tap (21) smoke exhaust (7) is opened to small-power shelves runnings, upwards pull handle (43), the below of counterweight lifting transparent slip lid (6) and guide wheel B (41) perk, slip lid sealing strip (37) separates with slideway (16), guide wheel A (40) contacts with slideway (16) with last travelling wheel (35), continue upwards to pull handle (43), counterweight lifting transparent slip lid (6) upwards can be slided into meta along slideway (16), make the stokehold neutral be transferred to moderate state.Counterweight lifting transparent slip lid (6) is gone up when sliding, by chain wheel rope B (38) and slip lid counterweight pulley (18) slip lid counterweight (39) is upwards promoted, simultaneously, slip lid counterweight (39) is landing downwards, the swing arm counterweight (31) of its top is landing downwards thereupon also, swing arm counterweight (31) makes swing arm (28) be with magnet (26) to swing to the below from the top by chain wheel rope A (30) and swing arm counterweight pulley (29), because the wind-force effect of smoke exhaust (7), dustproof blade (24) still can remain on open mode, and it is outdoor that oil flue waste gas is discharged to swimmingly.Middle frame forward end seal bar (15) and slip lid sealing strip (37) can make the top and the both sides sealing of counterweight lifting transparent slip lid (6), and it is indoor that oil flue waste gas can not leaked into.
When operating than big-movement in the kitchen range top (1) top with frying pan (3) cooking or need, can handle blower fan draws gauge tap (21) smoke exhaust (7) is opened to high-power shelves running, upwards pull handle (43), the below of counterweight lifting transparent slip lid (6) and guide wheel B (41) perk, slip lid sealing strip (37) separates with slideway (16), guide wheel A (40) contacts with slideway (16) with last travelling wheel (35), continue upwards to pull handle (43), counterweight lifting transparent slip lid (6) upwards can be slided into upperly along slideway (16), make the stokehold neutral be transferred to big state.Because the wind-force effect of smoke exhaust (7), dustproof blade (24) still can remain on open mode, and it is outdoor that oil flue waste gas is discharged to swimmingly.
Culinary art finishes, close smoke exhaust (7) power supply, remain on counterweight lifting transparent slip lid (6) upper, or slide to upper by the next, meta, by slip lid counterweight (39), swing arm counterweight (31), swing arm (28), magnet (26), be subjected to the interlock of magnetic spare (27) and dustproof blade (24), with the smokejack sealing, prevent that dust, mosquito and muroid are in the smoke discharging pipe inlet chamber.
Patent of the present invention makes operation very light and handy, easy by counterweight, interlock and magnetic control design.Under the condition that is with or without the high smokejack of strong suction, oil flue waste gas is being got rid of under the clean prerequisite, can be according to the characteristics and the needs of various cooking methods, the neutral size in regulated at will kitchen range top the place ahead, and correspondingly regulate the size of power of fan or close blower fan.When the culinary art that need not operate, the stokehold neutral is turned down, also can make dustproof blade stay open the smoke evacuation state when closing blower fan.Finish using and dustproof blade is in close, be in dust protection, mosquito proof and anti-muroid state.
When power failure and electrical fault, taking does not as far as possible need for a long time the neutral of kitchen range top top to be transferred big cooking method, is discharged into indoor to reduce oil flue waste gas to greatest extent.Even if do not having a power failure and motor when intact, want to save electricity charge spending, reduce oil flue waste gas again to greatest extent and be discharged into indoorly, do not need also to take as far as possible for a long time the neutral of kitchen range top top to be transferred big cooking method, reach the effect of saving electric energy, noiselessness and environmental protection.
