Description
Technical field
The invention belongs to be placed on the technology of frying pan fume eliminating and steam on combustion gas or oil range, especially to frying pan
Middle blowing hot-air carries out the method and corresponding device of oil smoke and steam in elimination pot.
Background technology
When present cooking, a large amount of oil smoke or steam can be all generated, oil smoke or steam all endanger the health of people.Use smoke exhaust ventilator
On frying pan take out can not be fully drawn out oil smoke or steam, extract out oil and meanwhile also pollute air.
Invention content
The object of the present invention is to provide a kind of with being blown into hot wind into pot, the method for blowing down oil smoke and steam in pot;Also carry
Hot gas is wasted for a kind of stove side below pot, is blown into pot by pipeline, blows down the device of oil smoke and steam in pot.
Present disclosure:
The method for blowing down oil smoke steam in pot with blowing hot-air, it is characterised in that:Into frying pan just on the food of frying
Spray the hot gas of 70-95 degree Celsius.When being sprayed onto above the dish fried with the hot gas of 70-95 degree Celsius, 70-95 degree Celsius
Hot gas make to can not see oil smoke and steam on its frying pan, these hot winds have blown down oil smoke steam in pot.
It is preferred that the hot gas of 75-85 degree Celsius is just sprayed on the food of frying into frying pan.The hot gas of these 75-85 degree
Oil smoke steam in pot is blown down, maximum temperature only has 75-85 degree Celsius, is only not easy to scald people.
The device of oil smoke steam in pot is blown down with blowing hot-air, it is characterised in that:Including the double boiler circle being nested inside and outside one
1, the height that 2 top surface of internal layer pot circle shorter h than 3 top surface of outer layer pot circle is 1-3 centimetres;Further include a wind turbine 4, the wind turbine 4 into
It is connected to tracheae 5 between gas port and outer layer pot circle 3;Wind turbine 4 is equipped with discharge pipe 6.
The present apparatus is taken in inside and outside 1 interlayer of double boiler circle being nested, and there is no cooking, the discarded waste hot airs for function of cooking
These discarded waste heat gases are passed through tracheae 5 by body, in the injection to cooking, the pot cooked of wind turbine 4, are made cooking in pot, are cooked
It can not see oil smoke and steam.Because of the hot vapour body in inside and outside 1 interlayer of double boiler circle being nested, by tracheae 5, it is blown with wind turbine 4
General hot vapour temperature is in 70-95 degree Celsius when in cooking, the pot cooked.
The bottom surface of internal layer pot circle 2 is connect with the sealing bottom surface of outer layer pot circle 3 preferably, makes internal layer pot circle 2 and outer layer pot circle 3
Interlayer space there was only upper end be hatch frame.Enter hot gas of the internal layer pot circle 2 with 3 interlayer space of outer layer pot circle from upper end
Tracheae 5 can be flowed into.
Wind turbine 4 is universal rotational connection structure with discharge pipe 6, one or more porous relieve heat is equipped in the pipe of discharge pipe 6
Plate 16, a central shaft for crossing diameter is fixed in the one side of hole air dispersion plate 16, and the both ends of central shaft are corresponding on 6 wall of discharge pipe
Two holes rotation connection;6 wall of discharge pipe is stretched out in one end of central shaft, stretches out outside central shaft and 6 wall of discharge pipe of 6 wall of discharge pipe
Clamping apparatus cassette connection.
Hole air dispersion plate 16 in 6 pipe of discharge pipe becomes the gas of wider area diverging for the hot gas of blowout, makes outlet air
The hot gas that pipe 6 is blown out completely is distributed in when to frying pan in entire pot range above, and reduce the hot gas of blowout
Atmospheric pressure does not blow the dish in stir-fry in pot.
It is vertically arranged vertical segment 7 to have one in tracheae 5, is set in vertical segment 7 there are one upper end is small, the big platform shape in lower end
Gas webmaster 8 is filtered, the lower end of platform shape filtering gas webmaster 8 is fixedly connected with 7 inner wall of vertical segment;Platform shape filters gas webmaster 8
Upper end be fixedly connected with the vertical segment mouth 9 on 7 top of vertical segment, exhausted air quantity regulation pipe 10 is connected with out on vertical segment mouth 9, is gone out useless
Tolerance regulation pipe 10 is equipped with hot gas stream control valve 11.
Platform shape filtering gas webmaster 8, which is mainly removed, to be obtained from inside and outside 1 interlayer of double boiler circle being nested in hot vapour body
Slag object, it is clean to ensure that wind turbine 4 is blown to the gas in pot.
Go out slag object of the exhausted air quantity regulation pipe 10 for being discharged in hot gas, goes out the adjusting hot gas stream of exhausted air quantity regulation pipe 10
The method of amount adjusts the temperature that wind turbine 4 is blown out, and hot vapour temperature exists when making it in the injection to cooking, the pot cooked of wind turbine 4
70-95 degree Celsius.
Tracheae 5 divides to be connected to pipeline section 12 with outer layer pot circle, vertical segment 7, being connected to pipeline section 13 with wind turbine, between these three pipeline sections
The inside and outside energy rotary type connection being nested;It is connected to pipeline section 12 with outer layer pot circle and incoming air conduit 14 is arranged below, is set on incoming air conduit 14
Have into air temperature-adjustment valve 15.
The inside and outside energy rotary type connection being nested between these three pipeline sections, so that its discharge pipe 6 is become universal rotating function
Component.The larger particles for being used to be discharged in hot gas into air temperature-adjustment valve 15 also can be used into the how many method of air and adjust tracheae 5
In hot gas temperature, hot vapour temperature is in 70-95 degree Celsius when making it with the injection of wind turbine 4 in cooking, the pot cooked.
Advantages of the present invention:When using apparatus of the present invention, temperature be 70-95 degree hot vapour body Celsius be blown frying pan,
When pot for cooking rice, slaughterhouse etc. are upper, it is that can not see oil smoke and steam completely at once to blow down effect.And existing any smoke extractor all cannot
Reach the relatively fruit that can not see oil smoke and steam completely.
For apparatus of the present invention of family, as long as 80 watts of wind turbine, and minimum 200 watts of existing any smoke extractor, it is seen that this
Invention device is energy saving.
For apparatus of the present invention that commercial two stoves of larger kitchens merge, as long as 160 watts of wind turbine, and commercial two stoves of existing larger kitchens
Minimum 2000 watts of combined smoke extractor, it is seen that apparatus of the present invention are energy saving.
Apparatus of the present invention are more simple in structure than any smoke extractor, low manufacture cost.
