Abstract
The utility model discloses an oil fume remover of a negative pressure type, comprising an oil fume hood and an oil fume channel, wherein, the outlet of the oil fume hood can be hermetically connected with an interface at the lower end of the oil fume channel through screws; the upper end of the oil fume channel is designed into a bent tube; the outlet of the bent tube of the oil fume remover is inserted into a main channel; the inlet end of the main channel is provided with a blower or a fan; the outlet of the main channel has the same direction as the outlet of the bent tube of the oil fume exhausting channel. The utility model has the advantages that the oil fume exhausting effect is good; oil fumes can be avoided from being depositing in the blower; the difficulty for cleaning the oil fume remover can be effectively reduced.
Description
The utility model relates to a kind of kitchen utensils, is specifically related to a kind of smoke exhaust.
The oil smoke that produces during culinary cuisine both contaminated air is detrimental to health, and oil smoke is also on various apparatus, door and window and the wall attached to the kitchen.For addressing this problem, designed various smoke exhaust ventilators, but its basic structure and operation principle all are in the exit of enclosure blower fan to be set, rely on the draft of blower fan oil smoke to be discharged outdoor.This is with regard to producing a problem inevitably, and is how long have more than is needed, and a large amount of oil smoke is with regard on inwall, fan blade and the motor of deposition attached to smoke exhaust ventilator, and is greasy, sticky, and blower fan rotates difficulty on the one hand, and draft weakens, causes the fan life reduction; Moreover, sweep very difficulty of health.This is also proposed some technical schemes, such as: " sticking oil ", " fans entrance is provided with screen pack " or the like show but put into practice, and fail to tackle the problem at its root.
The purpose of this utility model provides a kind of rational in infrastructure, utilizes the power of blowing of blower fan or fan to make the oil smoke passage produce negative pressure, both oil smoke can be drained, and can effectively avoid polluting the suction type smoke exhaust of blower fan again.
The purpose of this utility model is achieved in that
The suction type smoke exhaust comprises an oil smoke cover and oil smoke passage, and the outlet of oil smoke cover and oil smoke passage lower end interface can connect with bolt seal; Oil smoke passage upper end is designed to one or more bend pipes, and the outlet of mist extractor passage is inserted in the main channel, and the outer wall of mist extractor passage and the outer wall of main channel are answered sealed attachment or welding.The arrival end of main channel is provided with one or many typhoons machine or ventilating fan, and the main channel outlet is identical with the direction of mist extractor passage winding pipe exit.
The utility model has been broken through the tactic pattern of existing smoke exhaust ventilator, make originally and oil smoke all to be sucked blower fan become with blower fan the oil smoke of mist extractor passage winding pipe exit is blown away from the main channel outlet, the oil smoke that produces during culinary art does not pass through blower fan, avoided the pollution of oil smoke effectively to blower fan, improved the operating efficiency of smoke exhaust, prolong service life of equipment, alleviated the difficulty of cleaning lampblack absorber simultaneously greatly.The utility model is skillfully constructed, and modern design can be widely used in family kitchen, collectiveity canteen and hotels, has the good prospect of marketing.
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is the structural representation according to the suction type smoke exhaust that the utility model proposes.
Describe details and working condition in detail below in conjunction with Fig. 1, but content of the present utility model is not limited to shown in the accompanying drawing according to the concrete device that the utility model proposes.
This device comprises an oil smoke cover 4 and an oil smoke passage 3, and oil smoke cover 4 and oil smoke passage 3 lower end interfaces can be used bolt 5 sealed connections; Oil smoke passage 3 upper ends are designed to a bend pipe, mist extractor passage (3) is 90 ° of bend pipes, the outlet 10 of mist extractor passage bend pipe is inserted in the main channel 9, the arrival end 1 of main channel 9 is provided with an axial fan 6 or utilizes the blower fan of existing smoke exhaust ventilator, the inlet of axial fan 6 communicates with atmosphere, main channel outlet 2 is identical with the direction of the winding pipe exit 10 of mist extractor passage 3, and winding pipe exit end face 10 should place the main channel to export 2 rear portion, and should keep suitable coverage.
During culinary art, open axial fan 6, axial fan sucks air in the main channel 9, and blow to the port of export 2 of main channel, this moment mist extractor passage 3 in and outlet 10 places of bend pipe just form negative pressure naturally, oil smoke and vaporific gas 7 that kitchen range 8 tops in kitchen produce, interior and blown away in time by oil smoke passage bend pipe suction main channel 9, the smoke discharging effect spy is good, does not deposit greasy on the pressure fan 6 again.
