Abstract

An air preheating gas cooker is provided. Each inner and outer ring hybrid tube of the gas cooker is composed of an outer sleeve and an inner sleeve, and a gas nozzle is inserted into an opening of the inner sleeve; the air is preheated by using the waste heat of a burner so as to increase the speed of flame propagation, the reaction rate in a reaction zone and the burning temperature, thus improving the burning intensity. When some component gases are used, by spraying water onto the outer sleeve with a needle-typed water pipe, the temperature rising process can also be intensified, the content of CO can be reduced, the sufficient burning is ensured, and the air preheating effect is improved.

Description

The air preheat gas-cooker
Technical field
The utility model relates to the culinary kitchen range of domestic gas apparatus, particularly a kind of air preheat gas-cooker.
Background technology
Utilizing liquefied gas, natural gas is gas appliance commonly used in family and the public utilities life for the gas-cooker of source of the gas.But present gas-cooker air is in use entered by the end of Internal and external cycle mixing tube group mostly, does not pass through preheating, thereby reaction speed, ignition temperature and combustion intensity in the flame propagation velocity, reaction zone all do not reach better.Because the component difference of different combustion gas, its effect of combustion also is not quite similar, and some combustion gas is in use also needed to adopt the water spray means to strengthen temperature-rise period, reduces CO content, guarantees fully burning.
The utility model content
At the defective of above-mentioned similar technology, the purpose of this utility model provides a kind of gas-preheating gas-cooker of energy preheated air.
The technical solution of the utility model is: 1. each Internal and external cycle mixing tube group is made up of outer tube and inner sleeve, and the outer tube perisporium has the miniature air air admission hole, and gas nozzle inserts in the inner sleeve.2. the outer tube end has the air inlet hole, and the tolerance control panel opens or closes the air inlet hole.The surplus temperature preheating that cold air enters the burned device in back by the outer tube opening part when 3. using, preheated air and combustion gas mixing are being sent into burner after entering inner sleeve.4. the bottom is provided with the needle-like water pipe in outer tube, sprays water during for some component combustion gas of use.
The utility model has the advantages that: 1. preheated air can improve flame propagation velocity, increases the reaction speed in the reaction zone, improves ignition temperature, thereby increases combustion intensity.2. when using some component combustion gas, adopt the needle-like water spray, can strengthen the temperature rise process, reduce CO content, guarantee fully burning, improve the air preheat effect.
Description of drawings
Fig. 1 has the structural representation of needle-like water pipe (7) for the utility model.
Fig. 2 is the A-A cutaway view of Fig. 1.
The specific embodiment
Now in conjunction with the accompanying drawings, technology contents of the present utility model is done further narration.
Gas-cooker generally is made up of Internal and external cycle mixing tube group (1), gas nozzle (4), air inlet hole (5), tolerance control panel (6), burner (8), knob (9) and gas inlet pipe (10).Each Internal and external cycle mixing tube group (1) is made of outer tube (2) and inner sleeve (3), and the perisporium of outer tube (2) has the miniature air air admission hole, and gas nozzle (4) inserts inner sleeve (3) opening part.The blind end of outer tube (2) has air inlet hole (5), and tolerance control panel (6) can open and close air inlet hole (5).Needle-like water pipe (7) is installed in the interior bottom of outer tube (2).
Before gas-cooker used, cold air entered outer tube (2) and the inner sleeve (3) from opening part and air inlet hole (5) of outer tube (2) respectively.Open knob (9), combustion gas enters burner (8) burning by gas inlet pipe (10), gas nozzle (4) and inner sleeve (3).Enter inner sleeve (3) and combustion gas mixing again after the surplus temperature preheating of the burned device of cold air (8) of outer tube (2) subsequently.
The miniature air air admission hole that the utility model outer tube (2) perisporium has can be a circular hole, also can be the bar shaped otch.
When using the combustion gas of some component, can utilize needle-like water pipe (7) to spray water to outer tube (2).Needle-like water pipe (7) places in the kitchen range, and cistern and gauge tap are coupled.Needle-like water pipe (7) generally can not set up yet.

Claims (4)

1, a kind of air preheat gas-cooker, it comprises Internal and external cycle mixing tube group (1), gas nozzle (4), air inlet hole (5), tolerance control panel (6), burner (8), knob (9) and gas inlet pipe (10), it is characterized in that each Internal and external cycle mixing tube group (1) is made of outer tube (2) and inner sleeve (3), gas nozzle (4) inserts inner sleeve (3) opening part.
2, a kind of air preheat gas-cooker according to claim 1 is characterized in that the miniature air air admission hole that outer tube (2) perisporium has can be a circular hole, also can be the bar shaped otch.
