Abstract

The utility model relates to a closed gas range. A circular ring-shaped closed surface is formed by the contact between the bottom of a pan and the panel of the closed gas range. By the closed surface, the waste gas after burning and heat transfer is involved in an eccentric disk. One side of the eccentric disk far away from the circle center of a range end is provided with an exhaust outlet which is connected with a discharge flue. The discharge flue is connected with an outer range chimney externally. Burnt waste gas in the range is exhausted to the open air by the outer range chimney finally. Using the closed gas range, a favorable air environment of kitchens can be maintained, and the energy can be convenient to save.

Description

Closed gas range

The utility model is to be the closed gas kitchen ranges of main fuel with various imflammable gas (as coal gas, natural gas etc.).

At present, the combustion gas mode of gas kitchen ranges all is to adopt open combustion system.That is, the combustion chamber of kitchen range directly communicates with space, kitchen range room, and the waste gas after the kitchen range internal combustion directly is discharged into space, kitchen range room.Obviously, the waste gas of being discharged after its internal-combustion when using present this kitchen range is very harmful to health, wherein also contain in a large number without the CO gas after the abundant burning, CO gas is hypertoxic gas, and it is seriously endangered and coerces people's life security In addition, at present the kitchen range that use are owing to be to adopt open combustion system, its a large amount of waste heats have only in vain along with toxic emission among space, kitchen range room, like this, both wasted energy, make kitchen range room environment (especially time hot summer) become extremely abominable again.

The purpose of this utility model is exactly to utilize the new technique device of a cover, make combustion gas in the kitchen range can be closed in one with isolated combustion chamber, space, kitchen range room in burn.Like this, the burnt gas of these kitchen range will directly be discharged into never again and have been gone in the space, kitchen range room; Simultaneously, enforcement of the present utility model also helps people and carries out the waste heat back production, to reach the purpose of saving the energy and protection kitchen range room environment.

The utility model is realized by following technological means: gaseous mixture burns in a combustion chamber based on a flow guiding disc after kitchen range ejection, its flame under the guiding of flow guiding disc with pan (bottom surface) transmission of heat by contact.The pan bottom surface is flattened on the kitchen range panel, and therefore, pan bottom surface and contacting of kitchen range panel have formed the sealing surface of a kind of garden annular.The sealing surface of this garden annular impels the overheated flame of biography after waste gas is done in change, can only be rolled within the eccentric disc under the obstruct of pan bottom surface and kitchen range panel.The eccentric disc of garden shape and the garden heart between the kitchen range differ certain distance, are having an exhaust entrance from kitchen range garden heart eccentric disc one side farthest.The kitchen range burnt gas to smokejack and gas outlet, finally is disposed to outdoor through the kitchen range smokestack through exhaust entrance again.

Concrete enforcement of the present utility model can be by following embodiment and description of drawings thereof

Fig. 1 is the longitudinal sectional drawing of a kind of embodiment front view of the present utility model;

Fig. 2 is the vertical view of Fig. 1;

Fig. 3 is the left view of Fig. 1;

Fig. 4 is that Fig. 1 places behind the pan cutaway view along Fig. 2 A-A line;

With reference to Fig. 1, mixed certain Air mixing combustion gas in the air mixture chamber ［ 9 ］ in kitchen range ［ 8 ］ from kitchen range ［ 8 ］ ejection and burning.［ 4 ］［ 5 ］［ 7 ］ are the inlets of auxiliary air, and from then on the porch is irritated into air and can be made combustion gas obtain burning more completely.Flow guiding disc ［ 6 ］ is the main body of combustion chamber ［ 10 ］, and its shape is the garden dish, and its vertical face cuts open the figure arcuation that figure is certain rule, and its effect is that conduct heat and reflect certain heat energy in the pilot flame upper reaches more effectively.Flow guiding disc ［ 6 ］ fully is enclosed within the eccentric disc ［ 2 ］ all around.The effect of eccentric disc ［ 2 ］ is to collect waste gas and impel waste gas successfully to be disposed to outside the kitchen range.The garden heart of eccentric disc ［ 12 ］ departs from the garden heart certain distance of kitchen range ［ 8 ］.(the kitchen range chamber uncovered ［ 11 ］ of kitchen range ［ 8 ］ and flow guiding disc ［ 6 ］ and panel ［ 3 ］ is with the garden heart).The exhaust entrance of kitchen range ［ 2 ］ is located at apart from kitchen range ［ 8 ］ garden heart eccentric disc ［ 2 ］ one sides farthest.［ 13 ］ be the smokejack of kitchen range, burnt gas is drained into chimney outside the kitchen range through this flue, and then, burnt gas finally is discharged to outdoor by the kitchen range smokestack.［ 1 ］ be insulating collar, the material of insulating collar is general to adopt the material that has heat-proof quality as pottery etc.

［ 14 ］ among Fig. 2 are a kind of to be used when specializing in garden shape concave bottom iron pan cooking, and it has 3 (or more than 3), and their uniformly dispersings are gone up and become the corner relative in uncovered ［ 11 ］ of kitchen range panel.［ 15 ］ be the outlet of waste gas.［ 16 ］ are flat pans among Fig. 4.Pan lies on uncovered ［ 11 ］ of kitchen range panel in use, and it and panel ［ 3 ］ jointly are enclosed in burnt gas within the kitchen range, then are discharged to outdoor again outside smokejack and kitchen range smokestack etc. and make waste gas can only be involved in eccentric disc.

As long as gas kitchen ranges has adopted the technique device of above utility model, just can make the waste gas enter space, kitchen range room never again, thereby also arrive protection kitchen range room environment and the safeguard work personnel are healthy and the purpose of life security; Simultaneously, the technique device of above utility model also is convenient to people and is carried out the waste heat back production very much, and people can also reach the back production waste heat to save the good result of the energy as long as establish a water jacket again outside the kitchen range eccentric disc.
