Description
Technical field
The utility model relates to food baking technique field, is specifically related to a kind of multi-element type fume extractor.
Background technology
Baking oven utilizes hot-air convection, heat radiation and heat transfer to the device of cooking food, also can be used for making a general reference and penetrate with hot gas convection current, heat volume the device carrying out high-temperature process with heat transfer, baking oven is generally to be closed or semi-closed structure, when toasting product, the steam that product moisture evaporation is formed and the waste gas that burner produces are discharged through baking oven smoke exhausting pipe at top, make in stove, to remain suitable humidity and clean air, thus baked goods reaches best quality.
Existing baking oven top generally arranges the fume extractor of natural draught system formula or air-introduced machine mechanical smoke extraction formula, and it can not control exhaust smoke level, that is to say, according to the concrete condition of production, can not discharge steam and the hot-air of furnace chamber, operation inconvenience.
When as natural draught system, when requiring that the lower food of water content carries out baking for the higher food of water content or finished product, natural draught system, hydrofuge amount often do not reach requirement, make the ratio of furnace chamber internal steam too high, and food is occurred, and color and luster is uneven and the phenomenon that moisture is higher.
When utilizing air-introduced machine mechanical smoke extraction, although more moisture can be ensured and discards to discharge timely, but a large amount of hot gas can be discharged from fume extractor simultaneously, not only cause the waste of the energy, cause stove indoor air flow unstable simultaneously, cause stove fluctuations in indoor temperature comparatively large, when causing food, color and luster be partially white, time and roasting paste turns yellow.
Utility model content
For the deficiencies in the prior art, the purpose of this utility model is intended to provide a kind of multi-element type fume extractor, and it can according to the baking requirement of food, adjustment exhaust smoke level, improves the baking properties of food and avoids the waste of the energy.
For achieving the above object, the utility model adopts following technical scheme:
A kind of multi-element type fume extractor, comprises,
Four-way pipe, this four-way pipe have be communicated with the smoke exhaust pipe of baking oven the first joint, with external environment connect and to four-way pipe delivered inside extraneous air the second joint, with just right the 3rd joint of the second joint and and the first joint just to and the 4th joint for discharging flue gas;
Be arranged in the second joint for controlling the first control valve of extraneous air air inflow;
Be arranged in the 4th joint for controlling the second control valve of flue gas discharge rate;
Air-introduced machine, the inlet end of this air-introduced machine and the 3rd fittings;
Communicating pipe, its one end is communicated in the outlet side of air-introduced machine, the other end is communicated in the 4th joint, and the position be connected with the 4th joint communicating pipe is positioned at the outside of the second control valve.
Also be provided with a gas skirt between first joint and the smoke exhaust pipe of baking oven, in this gas skirt, be provided with a pull bar valve.
First control valve and the second control valve are butterfly valve.
The beneficial effects of the utility model are:
Compared to prior art, the utility model can according to the baking needs of reality, adjustment exhaust smoke level, realize natural draught system, mechanical type smoke evacuation and both fume exhausting types of being combined with each other, the quality of food-baking can not only be improved, reasonably arrange the discharge rate of flue gas simultaneously, can effectively prevent distributing of furnace chamber internal heat, reduce the waste of the energy.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the A-A sectional view of Fig. 1;
Wherein: 10, gas skirt; 11, pull bar valve; 20, four-way pipe; 21, the first joint; 22, the second joint; 23, the 3rd joint; 24, the 4th joint; 30, air-introduced machine; 40, communicating pipe; 50, the first control valve; 60, the second control valve.
Detailed description of the invention
Below, by reference to the accompanying drawings and detailed description of the invention, the utility model is described further:
As Fig. 1, shown in 2, for a kind of multi-element type fume extractor of the present utility model, it comprises four-way pipe 20, first control valve 50, second control valve 60, air-introduced machine 30 and communicating pipe 40, four-way pipe 20 have four joints, these four joints are respectively the first joint 21 be communicated with the smoke exhaust pipe of baking oven, with the second joint 22 of external environment connect, three joint 23 just right with the second joint 22, and four joint 24 just right with the first joint 21, wherein, first joint 21 is inner for the flue gas of baking oven inside being imported to four-way pipe 20, second joint 22 is inner for the air in external environment being delivered to four-way pipe 20, 4th joint 24 is for discharging the flue gas of four-way pipe 20 inside.First control valve 50 is arranged in the second joint 22, and it is for controlling the air inflow of extraneous air, and the second control valve 60 is arranged in the 4th joint 24, and it is for controlling the discharge rate of flue gas.The inlet end of air-introduced machine 30 is communicated with the 3rd joint 23, start air-introduced machine 30, four-way pipe 20 inside can be made to form negative pressure, one end of communicating pipe 40 is communicated in the outlet side of air-introduced machine 30, the other end is then communicated in the 4th joint 24, and the position be communicated with the 4th joint 24 communicating pipe 40 is positioned at the outside of the second control valve 60.
Said structure of the present utility model can realize different fume exhausting types as required:
When needs realize natural draught system, close air-introduced machine 30 and the first control valve 50, open the second control valve 60, now, baking oven inside smoke is by smoke exhaust pipe natural draught system.
When needs air-introduced machine 30 carries out mechanical type smoke evacuation, then close the second control valve 60, open air-introduced machine 30 and the first control valve 50, stir the first control valve 50, regulate the air inflow of extraneous air, when the air inflow of air increases, the draft of air-introduced machine 30 reduces, the exhaust gas volumn of discharging through communicating pipe 40 then reduces, the temperature of discharging flue gas reduces, otherwise, when the air inflow of air reduces, the draft of air-introduced machine 30 increases, exhaust gas volumn through discharging communicating pipe 40 increases, the temperature of discharging flue gas raises, so, can according to the baking situation of reality, control the size of exhaust smoke level, thus under the prerequisite guaranteeing food-baking quality, decrease the waste of the energy.
Certainly, on the basis of above-mentioned mechanical type fume exhausting type, the second control valve 60 can also be opened, realize the mixing fume exhausting type of natural draught system and mechanical type smoke evacuation, thus adapt to more toast requirement.
Above-mentioned first control valve 50 of the present utility model and the second control valve 60 preferably can adopt butterfly valve, in order to the discharge rate of the air inflow and flue gas that control air accurately.
Between the first above-mentioned joint 21 and the smoke exhaust pipe of baking oven, be also provided with a gas skirt 10, be provided with a pull bar valve 11 in this gas skirt 10, this pull bar valve 11 is in order to control unlatching or the cut out of multi-element type fume extractor.
To one skilled in the art, according to technical scheme described above and design, other various corresponding change and deformation can be made, and all these change and deformation all should belong within the protection domain of the utility model claim.
