Description

The energy-efficient preheating gas-supplying burning of a kind of gas-cooker assembly

Technical field

The utility model relates to a kind of gas kitchen ranges, exactly relates to the core apparatus on the gas kitchen ranges, a kind of gas-supplying burning assembly with energy-efficient effect that particularly disposes at gas-cooker.

Background technology

Although the gas-cooker with market sale of at present family's use is of numerous names, yet mainly is that external form is different, and the total bearing structure of its core apparatus-gas-supplying burning is basic identical. Following air intake gas cooker and upper air inlet gas cooker, their gas-supplying burning assembly is by being positioned at the low baking temperature of a small amount of fuel gas hole head gas supply cavity to be arranged on center, the sidewall, be arranged on this cavity annular air channel peripheral, that open wide up and down, and have the numerous main duration and degree of heating gas supply cavity that consists of of circle fuel gas hole by sidewall in this passage periphery, and the all-in-one-piece air supply pipe connector composition that will above-mentioned two cavitys links up. The gas-supplying burning assembly of this structure, because combustion gas does not mix with air before lighting, oxygen-free gas in the combustion gas, the limit supplemental oxygen of only keeping to the side to burn does not satisfy burning far away to the wilderness demand of oxygen, thereby will inevitably occur following problem: a, since the burning before the oxygen-free gas of combustion gas, make burning velocity slack-off by the combustion process supplemental oxygen, incomplete combustion, although the long temperature of fiery wick is but not high, the result has increased amount of consumed gas and has reduced efficiency of combustion; When the needs big fire, must strengthen the gas supply amount, yet generate long fiery wick because oxygen content is not enough, this fiery wick is scurried out from the bottom of a pan until the pot wall, even can alter pot and mouthful cause a pot wall to burn, and makes amount of heat lost. The oxygen-free gas of combustion gas before b, the burning, the cold air of being carried by the middle part air duct in the combustion process, rise and be flushed to the bottom of a pan, taken away a large amount of heats, cause the bottom of a pan, particularly the arc-shaped curved surface the bottom of a pan, its middle part temperature is far below the temperature of pot wall periphery, causes pot interior food not yet to boil and a pot wall is burnt. In a word, present all kinds of gas kitchen ranges, ubiquity have for hypoxgia, burning velocity slow fire flame temperature is low, the slow thermal efficiency of firing rate is low, the incomplete combustion amount of consumed gas greatly, is easily burnt the shortcomings such as the bottom of a pan.

Summary of the invention

Goal of the invention of the present utility model is: for the user provides a kind of oxygen supply foot, the fast flame temperature height of burning velocity, heats the energy-efficient preheating gas-supplying burning of the gas-cooker assembly that the fast thermal efficiency is high, burning full consumption combustion gas economizes.

Goal of the invention of the present utility model realizes by implementing following technical proposals:

The energy-efficient preheating gas-supplying burning of a kind of gas-cooker assembly, formed by the gas inlet pipe that connects with the ignition switch assembly and the combustion head that is connected this pipe, it is characterized in that: this combustion head includes and is contained in the top and is disc, diapire planar central and has and have in circumferential notch, the perisporium wall in an annular horizontal cavity of being cut off by vertical clapboard, the chamber near the preheater that fuel gas inlet and outlet are arranged on the bottom surface, dividing plate both sides, plug in preheater diapire circumferential notch, its top perimeter places on this preheater diapire, it is uncovered and be provided with the air fuel gas blender (hereinafter to be referred as blender) that air enters the hole by the diapire of air nozzle shutoff, sidewall to have a top, with self stentplacement the blender top sides along on, make the taper core body plug the gaseous core that divides the blender top is uncovered in, and the adapter that the blender air nozzle is connected with the preheater gas outlet.

Additional technical feature is: but a, the bracing frame of holder for supporting refuse pot on the pelvic surface of sacrum outside the periphery of preheater self. B, described blender are that the top is uncovered, diapire is by the hollow cavity of air nozzle shutoff by having of consisting of with the inverted conical platform on top sides edge and cylinder, and on its cylindrical section and frustum of a cone section sidewall, are respectively arranged with air and enter the hole. C, the air nozzle of described shutoff on the blender diapire are provided with air at the sidewall of its cavity and enter the hole, its with take over the diapire that is communicated with and be provided with the capillary lumen pore.

The utility model has the advantage of: because the top of preheating gas-supplying burning assembly is preheater, the heat of distributing with the external space to the bottom of a pan in the time of can be with fuel gas buring, absorb in the preheater annular horizontal cavity, make the cold combustion gas that just enters in this cavity be preheated and be lowered density, both improve the ability that oxygen is dissolved in combustion gas self, reduced again the utilization rate that radiation loss has improved heat energy. Simultaneously, owing to be provided with blender, the combustion gas that has been preheated is entered in the blender, just sneaked into the oxygen of capacity before fuel gas buring, speed is fast when having guaranteed fuel gas buring, flame temperature is high, firing rate is fast, the thermal efficiency is high, combustion gas is saved in burning fully and greatly.
