Description
Technical field
The utility model designs kitchen and bath's appliance field, more specifically designs a kind of isolated dual-energy-saving fume-exhausting of outer air source
Machine.
Background technology
Smoke exhaust ventilator comes into huge numbers of families as a kind of household cookware, is a kind of kitchen electricity of purification kitchen environment
Device.It is mounted on above kitchen health energy-saving range hood cooking stove, can will be generated in waste and cooking process that cooking stove burns
Harmful oil smoke is taken away rapidly, and discharge is outdoor, reduces pollution, purifies air, and has gas defence, explosion-proof safety guarantee to make
With.
Common range hood currently on the market is the room air for aspirating kitchen and the other rooms being connected with kitchen, quilt
The oil smoke that the air of suction is generated with hearth is discharged outdoor jointly after mixing.Therefore common range hood exists at least
Following three aspects problem：
One, when common range hood work, can will be including kitchen it is indoor by heating, humidifying, freeze, remove
Dirt, except haze etc. reason room air siphon away.At the same time, outdoor air is through the compensatory entrance again of the positions such as door, window
Interior, the electric appliances such as air-conditioning, humidifier, deduster need task again, can just make indoor extensive to before working common range hood again
State, this process must need to consume electric energy and time.
Two, when the work of common range hood, the air of compensation is typically to enter from the gap of door and window, normal conditions
Under, door and window has certain sealing performance, common range hood that larger air capacity is needed to be mixed with oil smoke, could be by oil smoke
It siphons away, to increase suction effect, the power of the wind turbine of common kitchen ventilator is increasing, and high-power range hood is in addition to itself energy consumption
Cost and noise are larger outer, more further increase the cost that room air is handled again.
Three, when the work of common range hood, it is undesirable to there is also oil smoke suction effect；By kitchen and toilet Xia Shui
In the peculiar smell suction chamber in road, foreign flavor indoors is caused to spread unchecked；Room pressure is changed, the door and window for influencing kitchen and other rooms is normal
The problems such as switch, occurs.
Utility model content
The utility model is at least one defect overcome described in the above-mentioned prior art（It is insufficient）, provide a kind of outer air source every
From formula dual-energy-saving range hood.
The utility model is intended to solve above-mentioned technical problem at least to a certain extent.
In order to solve the above technical problems, the technical solution of the utility model is as follows：
A kind of isolated dual-energy-saving range hood of outer air source, including outer air duct, interior air duct and exhaust fan, the outer air duct enclose
It is located on the outside of interior air duct and the outer air duct is enclosed and is isolated with interior air duct, the exhaust fan is connected with interior air duct；In use, outer
Air duct and interior air duct are connected with outdoor, and the exhaust fan is used for outdoor exhausting.
Further, it is equipped with interior aerofoil below the interior air duct, the interior aerofoil is disposed around the lower section in interior air duct.
Further, outer aerofoil is equipped with below the outer air duct, the outer aerofoil is disposed around the lower section of outer air duct, described interior
Aerofoil and outer aerofoil constitute fan housing.
Further, it is provided with blowing mouth below the fan housing, the air-out direction of the blowing mouth is to center convergence.
Further, several air ports are evenly equipped on the interior aerofoil.
Further, several deflectors are equipped in the fan housing, the deflector is fixed on interior aerofoil, and deflector is fixed
Below air port, deflector tilts upwards and deflector and horizontal direction are in an angle.
Further, several deflectors are equipped in the fan housing, the deflector is fixed on interior aerofoil, and deflector is fixed
Below air port, and the radial direction of deflector and interior aerofoil is in an angle.
Further, it is communicated with exhaust fan on the outer air duct.
Compared with prior art, the advantageous effect of technical solutions of the utility model is：
One, outer gas source type dual-energy-saving range hood has the distinctive gather effect to oil smoke and suction track, ensure that
Its fume eliminating effect it is reliable and effective.
Two, outer gas source type dual-energy-saving range hood, which is delivered to the outdoor air near hearth, has buffer action, prevents oil
Dirt splashes on hearth table top and periphery wall.
Three, do not disappear when outer gas source type dual-energy-saving range hood is equipped with special inlet channel and outdoor phase together with, work
Pass through heating, humidification, refrigeration, dedusting, the room air managed except haze etc. in consumption kitchen and other rooms for being connected with kitchen,
Required air by it is outdoor continually enter near hearth mixed with oil smoke after siphon away, will not siphon away or interfere kitchen and and kitchen
The air in phase room, compensatory air is got in when avoiding common range hood work, and various electric appliances are to room air
Processing generates energy consumption again.This is one of energy saving point.
Four, outdoor air is delivered to by special inlet channel near hearth by outer gas source type dual-energy-saving range hood, no
It is influenced by door and window seal, while the interaction mode of extraneous air and oil smoke is special, the smaller power Fan of use
To reach ideal smoke absorption effect, it is not necessarily to high-power blower.This is the two of energy saving point.
Five, when outer gas source type dual-energy-saving range hood work, it will not interfere and consume the Interior Space including kitchen
Gas will not cause foreign flavor indoors to spread unchecked by the peculiar smell suction chamber of kitchen and toilet sewer；Indoor Air will not be changed
The problems such as pressure, the door and window normal switch for influencing kitchen and other rooms, occurs.
Six, outer gas source type dual-energy-saving range hood operating noise is small, easy to clean.
