A kind of gas-cooker
Technical field
The utility model relates to gas-cooker, relates generally to a kind of domestic type gas-cooker.
Background technology
Now the combustion head of most of on the market domestic type gas-cooker is general, traditional nozzle injection type combustion head, and in order to satisfy the needs of the different duration and degree of heating, it is set to inside and outside two-layer respectively, and the internal layer combustion head is used for the low baking temperature culinary art.But because in the prior art, combustion gas does not just directly output to combustion head through any processing and burns, make combustion gas in when burning and air undercompounding, thereby reduced fuel gas buring efficient, cause a large amount of combustion gas wastings of resources, particularly when using the internal layer combustion head to carry out the low baking temperature culinary art separately, this waste is more obvious.
The utility model content
Technical problem to be solved in the utility model is that a kind of gas-cooker that can significantly improve internal layer combustion head efficiency of combustion is provided.
The utility model solve the technical problem the technical scheme that is adopted, a kind of gas-cooker, comprise the burner that is connected with air inlet pipe, be provided with igniter and combustion zone in the described burner, described combustion zone is divided into internal layer combustion zone and outer combustion zone, the infrared ray burner plate is adopted in described internal layer combustion zone, and described outer combustion zone is the nozzle-type combustion head.
Further, described internal layer combustion zone employing porous ceramic plate.
Further, the utility model for make can access between combustion gas and the air fully mix after burning again, also be provided with air-supply arrangement on the described air inlet pipe, described air-supply arrangement is a centrifugal fan.
The beneficial effects of the utility model are, the utility model adopts porous ceramic plate, make the internal layer combustion zone have that burning area is big, gas-flow resistance is little, quick heating, the efficiency of combustion advantages of higher.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
As shown in Figure 1, the utility model gas-cooker comprises the burner 1 that is connected with air inlet pipe 5, be provided with igniter and combustion zone in the described burner 1, described combustion zone is divided into inside and outside two- layer 2,3, described internal layer combustion zone 2 is the infrared ray burner plate, and described infrared ray burner plate can be porous burner plate or the wire netting burner plate that a plurality of meshes are arranged.Preferred embodiment, described infrared ray burner plate is a porous ceramic plate.Described outer combustion zone 3 is general, traditional nozzle injection type combustion head.When using its internal layer combustion zone to cook, the porous ceramic plate that the utility model adopts has little, the quick heating of gas-flow resistance, efficiency of combustion advantages of higher.
The also described air inlet pipe of the utility model is provided with air-supply arrangement 4, and described air-supply arrangement 4 adopts centrifugal fan, makes combustion gas and air obtain fully mixing by centrifugal fan, thereby further improves the efficiency of combustion of combustion gas.
