Abstract
The utility model provides a clean fume exhaust fan, which is composed of a fume sucking and exhausting device and a clean air curtain device, wherein, a speed regulation fan of the fume sucking and exhausting device can provide sufficient wind rate and wind speed to suck and exhaust oil fumes by utilizing the operating principle that high wind speed can be used for producing siphon; the clean air curtain device is provided with a special fan for wind curtains. Airflow sent out by the fan can be evenly distributed to each nozzle of the wind curtains by a wind channel formed by a suction chamber and a casing. Thus after the airflow is jetted out, an integral wind curtain is formed on the surface of an inner wall of the oil smoke suction chamber to cause the oil fumes have no chance to be adhered on a casing wall. Thus the clean fume exhaust fan can be ensured to be clean without greasy dirt.
Description
The utility model belongs to lampblack absorber, particularly a kind of culinary clean range hood.
Before the utility model, various types of range hoods, all be the oil smoke aspiration to be gone into mixing chamber by ventilating fan, arrange to outlet through passage again, the operation principle of this suction makes oil smoke gas directly contact blade, mixing chamber and the passage of fan, so the container inner wall of process just inevitably adhere to a large amount of greasy dirts, and greatly reduce the operating efficiency of ventilating fan, and cause environmental pollution.Also there is not thoroughly to solve the problem of not gluing greasy dirt inside and outside the range hood up to now.
The purpose of this utility model aims to provide a kind of clean range hood, it utilizes the operation principle of the siphonage that high wind speed produces, and host part and oil smoke gas are isolated fully, has thoroughly solved the difficult problem that greasy dirt adheres to host part.
The technical solution of the utility model realizes as follows.
A kind of clean range hood, it has the control device of blower fan and gauge tap, it is characterized in that, it also has suction cigarette device and clean air curtain screen device to form, suction cigarette device is by main case, adjustable speed fan, band muffler spout, the oil smoke suction chamber, outlet is formed, adjustable speed fan is loaded in the isolation ward of main case top side, the main case of corresponding adjustable speed fan axis airflow direction is provided with band muffler spout, be provided with the oil smoke suction chamber and make one and perpendicular outlet with coexist main case opposite side on the axis of muffler spout, the inner at outlet is provided with muffler, and the outer end of outlet links to each other with outside smoke exhaust pipe; Clean air curtain screen device is made up of with the air curtain air channel that blower fan, air curtain nozzle and air curtain shell and oil smoke suction chamber form air curtain, and air curtain is located at the upside, air channel with motor, and the air curtain nozzle parallel with the oil smoke suction chamber is located at the lower end of oil smoke suction chamber; Buncher is connected with blower fan and gauge tap device respectively with motor with air curtain, and air curtain is crossed the air curtain nozzle with the wind circulation of blower fan oil smoke suction chamber inner wall surface is formed whole air curtain.
Above-mentioned outlet can be that interior import contraction outer vent spreads tapered shape.
Above-mentioned air curtain nozzle is a rectangle, and is uniformly distributed in respectively on the inwall of oil smoke suction chamber middle part and bottom.
Above-mentioned band muffler spout is that taper is closed up.
Characteristics of the present utility model are: be provided with in main frame one side and specialize in the blower fan that air curtain is used, the air-flow of sending by this blower fan by the air channel mean allocation to each air curtain nozzle, after making the air-flow ejection, form air curtain in the main case inner wall surface, oil smoke gas can't be sticked on the main frame shell wall, avoided contacting and adhesion of flue gas and host part fully, thereby guaranteed that the cleaning of range hood reaches the purpose of sticking oil.Below in conjunction with drawings and Examples the utility model is described in further detail:
Accompanying drawing 1 the utility model structural representation.
Accompanying drawing 2 A-A cutaway views of the present utility model
Among the figure: 1 adjustable speed fan, 2 band muffler spouts, 3 suction chambers, 4 contraction mouths, 5 mufflers, 6 diffusing openings, 7 outlets, 8 blower fans, 9 air curtain nozzles, 10 shells, 11 main cases, 12 blower fans and gauge tap device, 13 air curtain airflow directions, 14 oil smoke airflow directions.
As shown in Figure 1, start air curtain blower fan 8 earlier, after treating that the air curtain air-flow forms air curtain 13 by 9 ejections of air curtain nozzle, restart adjustable speed fan 1, and regulate the rotating speed gear as required, so that the speed of control working air current, at this moment oil smoke gas 14 can be inhaled in the suction chamber, working air current and oil smoke gas enter the contraction mouth 4 of outlet 7 thereupon, again through diffusing opening 6, oil smoke can be discharged from outlet.
Its operation principle is: by high rotating speed adjustable speed air curtain with working fluid that blower fan provided with certain energy, spray via nozzle, form high velocity air, because other gas in the suction chamber is taken away in the viscous effect that produces between high speed airflow and the turnover gas, make this place produce negative pressure, form vacuum, under the external atmospheric pressure effect, the oil smoke aspiration is gone in the suction chamber, and bring contraction mouth in the outlet in company with the air-flow of high speed operation, carry out energy exchange, in contraction mouth, because the turbulent fluctuation effect of gas molecule, working air current is passed to part of functions in the oil smoke gas of suction, working air current is progressively slowed down, the speed that the oil smoke gas that is inhaled into progressively accelerates to arrive the terminal two strands of air-flows of contraction mouth is gradually consistent, and mixed process is finished substantially, enters diffusing opening then, flow velocity progressively reduces, and is discharged by outlet.Avoid oil smoke to adhere to for making the main case inner wall surface, the air channel that main case and air curtain shell form, provide air flow source by air curtain with blower fan, air-flow is dispensed to equally distributed a plurality of nozzles of main frame shell wall lower end through the air channel, air-flow by the nozzle ejection forms air curtain in the main case inner wall surface, after air curtain forms, main case and oil smoke air bound can be left, ensure the cleaning of casing inner wall.
The utility model has been avoided contacting and adhesion of flue gas and host part fully, reaches the purpose of the real cleaning of sticking oil.
