Abstract

The utility model relates to a cooking stove burning various gas fuels. Compared with the existing gas cooking stove, the utility model is characterized in that the stove end chamber is reduced, the injection chamber is lengthened, and the structure sizes of the fire trough and the burner port are changed. The utility model has the versatility of various gas fuels and can burn manufactured gas, petroleum liquid gas, petroleum natural gas, etc. The combustion performance is good. The utility model can ensure the requirements for cooking in the daily family life and the social catering trade.

Description

Stove using various gas fuels

The utility model belongs to a kind of cooking stove that uses multiple combustion gas.

Cooking stove is the mess kit of people's daily life and social catering trade indispensability.Its thermal source is from aspects such as coal, oil, petroleum gas and electricity.The fuel of present widely used combustion gas cooking stove is along with the development of China's energy industry, by the artificial coal gas of original single variety, develops into oil liquefied gas, petroleum gas of many kinds etc.And each department are limit owing to self-condition, and the combustion gas kind of use is given priority to again.Thereby present widely used combustion gas cooking stove, because φ 100mm burner chamber is big, the ejection cavity of 80-130mm is short, fire trough and the burner port unreasonable structure of dark 3mm, 7mm make the combustion gas cooking stove that uses at present exist following weak point:

1, can not adapt to the needs that use many kinds fuel;

2, burning is undesirable, and thermic load, the thermal efficiency, CO content all do not meet standard;

3, easily fire, tempering, ring detonans are taken off in generation.

The purpose of this utility model is to overcome above-mentioned weak point, provides a kind of can the adaptation to use multiple combustion gas, standard compliant cooking stove.

In order to realize above-mentioned purpose, the core of the technical solution that the utility model adopts is to dwindle the burner chamber, lengthening ejection cavity, the planform of change fire trough and burner port.It is made up of nozzle, spring, interior aerofoil, outer aerofoil, stone or metal plate for standing a stove on as a precaution against fire, pot frame etc., it is characterized in that the burner chamber size on the burner is reduced into φ (65-90) mm, ejection cavity length dimension lengthening is (150-200) mm, entrance port φ (10-13) mm, exit wound of bullet φ (22-26) mm, fire trough on the top cover is of a size of (1.2-2.5) mm deeply, long (8-10) mm.

The utility model is owing to adopted above-mentioned technical solution, and its advantage is:

1, the multiple combustion gas such as artificial coal gas, oil liquefied gas, petroleum gas of can burning.

2, have good burning performance, every performance indications all meet GB.

3, do not have and to take off bad phenomenon such as fire, tempering, ring be quick-fried.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is a kind of specific embodiment general structure schematic diagram of the present utility model.

Fig. 2 is a cap structure schematic diagram among Fig. 1.

Fig. 3 is the vertical view of Fig. 2.

Fig. 4 is that the B of Fig. 3 is to launching schematic diagram.

Shown in Fig. 1-4, the embodiment general structure is to constitute like this: be connected with stone or metal plate for standing a stove on as a precaution against fire 6 above the head of burner 10, pot frame 9 is set on the card.Be equipped with top cover 7 above the head annular groove of burner 10, formed annular burner chamber 12.The tail end of burner 10 is connected with interior aerofoil 3, and the plate face is provided with air door 15, and the center is connected with nozzle 1, and interior aerofoil 3 outsides are equipped with outer aerofoil 4, and its face is provided with air door 16.Between inside and outside aerofoil 3,4 and the nozzle 1 spring 2 is housed.Top cover 7 is along being provided with groove one by one on the lower inclined plane circumference, and formed fire trough 11 with burner 10 corresponding inclined-planes, also is provided with burner port 8 above the top cover 7, and burner port 8, fire trough 11 all communicate with burner chamber 12.The cooking stove course of work is like this: the combustion gas that has certain pressure is ejected in the tail end cavity of ejection cavity 5 by nozzle 1, form one gas-flow, have certain flow and flow velocity, thereby the air outside the stove is by air door 15,16 enter in the tail end cavity, 14 enter the cavity depth with gas-flow through the entrance port, because ejection cavity extends than prior art, make combustion gas fully mix with air after exit wound of bullet 13 enters in the burner chamber 12, enter fire trough 11 and burner port 8 that a burner chamber communicates at last, spray thus in the top of top cover 7 chance and burn through fire, regulate nozzle 1 and outer aerofoil 4 again according to cooking situation, control gas flow and air mass flow, promptly control the power of stove fire.

Claims

1, a kind of cooking stove that uses multiple combustion gas, it comprises nozzle, spring, interior aerofoil, outer aerofoil, stone or metal plate for standing a stove on as a precaution against fire, pot frame etc., it is characterized in that: the burner chamber size on the burner is reduced into φ (65-90) mm, ejection cavity length dimension lengthening is (150-200) mm, entrance port φ (10-13) mm, exit wound of bullet φ (22-26) mm, the fire trough on the top cover are of a size of (1.2-2.5) mm deeply, long (8-10) mm.
