Abstract
The invention discloses a range hood comprising a housing, an air outlet pipe, an air suction pipe, an air multiplying ring, and a control panel. The housing is fastened on a wall surface. A first end of the air outlet pipe communicates with the outdoor area, and the second end of the air outlet pipe communicates with the inner part of the housing. An air inlet of the air suction pipe is positioned at an opening on the bottom of the housing. An air outlet of the air suction pipe communicates with the air outlet pipe. The pipe diameter of the air suction pipe is gradually reduced from the two ends to the middle. The air outlet of the air multiplying ring is oriented upwards and is fastened on the middle or lower part in the air suction pipe. The control panel is fastened on the housing. With the range hood provided by the invention, oil smoke in environments with severe oil smoke can be rapidly eliminated. The range hood has the advantages of high suction force, high oil smoke removing speed, and easy clean. The range hood is energy-saving and power-saving.
Description
Technical field
The present invention relates to a kind of air cleaning unit, espespecially a kind of range hood.
Background technology
Present range hood is generally to pass through drive motors, make wind wheel make High Rotation Speed, make the certain interior negative pressuren zone that forms of spatial dimension in cooking stove top, indoor soot gas is sucked in range hood, thereby realize the purpose of flue gas along fixing path discharge, but the range hood suction of conventional wind wheel formula is limited, can not satisfy well the demand of oil smoke discharge in larger oil smoke surroundings, and power consumption power is strong.
Summary of the invention
The object of the invention is to overcome the defective of prior art, and a kind of range hood is provided, realized that the oil smoke of larger oil smoke surroundings is got rid of fast, had advantages of that suction is strong, mist extractor speed is fast, easy to clean, energy saving.
The technical scheme that realizes above-mentioned purpose is:
A kind of range hood of the present invention comprises:
One housing, described housing is anchored on metope;
One discharge pipe, the first end of described discharge pipe is communicated with outdoor, and the second end of described discharge pipe passes in described housing;
One aspiration channel, the air intake vent of described aspiration channel are positioned at an opening part of described housing bottom, and the air outlet of described aspiration channel is communicated with described discharge pipe, and the caliber of described aspiration channel is successively decreased to the middle part by two ends;
One air multiplication circle, described air multiplication are irised out the air port upwards and are anchored on middle part or bottom in described aspiration channel;
One control panel, described control panel is anchored on described housing.
One screen pack removably is anchored on the bottom of above-mentioned aspiration channel.
Above-mentioned screen pack is inverted cup-shaped.
The both sides of above-mentioned opening are provided with a pair of chute, and in described chute, sliding establishing is fixed with a baffle plate.
The present invention has been owing to having adopted above technical scheme, makes it have following beneficial effect to be:
Be used for indoor oil smoke is discharged with the outdoor discharge pipe that is communicated with; The air multiplication circle that air outlet makes progress has formed an air-flow that makes progress, indoor oil smoke sucked in aspiration channel, and the little energy-conserving and environment-protective of power consumption; The caliber of aspiration channel is successively decreased to the middle part by two ends and has utilized fluid velocity and the characteristics that are inversely proportional to by the pipeline section area in the Bernoulli's theorem, realize the high speed ejection of oil smoke in the aspiration channel upper tube, and at aspiration channel middle part formation depression, realize the quick suction of indoor oil smoke; Control panel is used for controlling range hood.Screen pack is used for the mist of oil that filtering sucks oil smoke; Sliding establishing is fixed with a baffle plate and can closes opening when range hood is not worked in chute, prevents in the external dust access to plant.
Description of drawings
Fig. 1 is the system architecture schematic diagram of range hood of the present invention;
Fig. 2 is the aspiration channel structural representation of range hood of the present invention;
Fig. 3 is the filter structure schematic diagram of range hood of the present invention.
The specific embodiment
The invention will be further described below in conjunction with specific embodiment.
See also Fig. 1, Fig. 2, a kind of range hood of the present invention comprises:
One housing 1, housing 1 is anchored on metope;
One discharge pipe 2, the first end of discharge pipe 2 is communicated with outdoor, is used for indoor oil smoke is discharged, and the second end of discharge pipe 2 passes in housing 1;
One aspiration channel 3, the air intake vent 32 of aspiration channel 3 are positioned at opening 6 places of housing 1 bottom, and the air outlet 31 of aspiration channel 3 is communicated with discharge pipe 2, and the caliber of aspiration channel 3 is successively decreased to the middle part by two ends;
One air multiplication circle 4, air multiplication circle 4 air outlets are upwards and be anchored on middle part or bottom in aspiration channel 3; The air multiplication circle 4 that air outlet makes progress has formed an air-flow that makes progress, indoor oil smoke sucked in aspiration channel 3, and the little energy-conserving and environment-protective of power consumption;
One control panel 7, control panel 7 are anchored on described housing 1, are used for controlling range hood.
The caliber of aspiration channel 3 is successively decreased to the middle part by two ends and has utilized fluid velocity and the characteristics that are inversely proportional to by the pipeline section area in the Bernoulli's theorem, make the interior gas of aspiration channel 3 upper tubes spray fast, and at aspiration channel 3 middle parts formation depressions, realize the suction continuously and healthily of indoor oil smoke; The oil smoke of having realized larger oil smoke surroundings gets rid of fast, has advantages of that suction is strong, mist extractor speed is fast, energy saving.
The both sides of opening 6 are provided with a pair of chute 61, and the interior cunning of chute 61 is established and is fixed with a baffle plate 62, can close opening 6 when range hood is not worked, and prevents in the external dust access to plant.
See also the bottom that Fig. 2,3, one screen packs 5 removably are anchored on aspiration channel 3, screen pack 5 is inverted cup-shaped, is used for the mist of oil that filtering sucks oil smoke.
When using this device, at first by control panel 7 opening devices, air multiplication circle 4 starts, it is by an air entry air amount, then the fan by an inside makes air in the interior acceleration of intensifier ring 41 and by the ejection of the air outlet above intensifier ring 4, and the air that the air-flow of ejection drives intensifier ring 4 belows forms an air-flow that axially makes progress along aspiration channel; Because being successively decreased to the middle part by two ends, the caliber of aspiration channel 3 utilized fluid velocity and the characteristics that are inversely proportional to by the pipeline section area in the Bernoulli's theorem, make the interior gas of air intake duct 3 upper tubes spray fast, and at air intake duct 3 middle parts formation one depressions, flue gas in suction chamber continuously and healthily, mist of oil in flue gas is under the effect of screen pack 5 in filtering to a lubricating cup, screen pack 5 and lubricating cup disassembling cleaning, the baffle plate 62 on closable opening 6 slide rails 61 does not prevent in the external dust access to plant during operative installations.
Below embodiment has been described in detail the present invention by reference to the accompanying drawings, and those skilled in the art can make the many variations example to the present invention according to the above description.Thereby some details in embodiment should not consist of limitation of the invention, and the scope that the present invention will define with appended claims is as protection scope of the present invention.
