Description

A multi-nozzle, large-flow, fully upward air-intake embedded burner for household gas stoves

technical field

The utility model relates to a burner for a household gas stove, in particular to a burner for an embedded gas stove with multiple nozzles, large flow rate and complete upward air intake.

Background technique

Household gas stoves are usually divided into two categories: desktop and built-in. Embedded burners mostly use two types: one is the upper air intake burner, and the other is the lower air intake burner. Most household gas stove burners with upward air intake adopt a single-nozzle structure, and the ejector adopts a vertical ejector structure. Therefore, this type of burner has only one gas nozzle to bear all the gas supply load, and independent adjustment of internal and external firepower cannot be realized. In addition, the vertical injector structure is limited by the installation height of the embedded cooker in the cabinet, and the injector part cannot be too long, so the mixing time of gas and primary air is not enough, the combustion is insufficient, and the thermal efficiency is low, so the power cannot be too large . Another household gas stove burner with downward air intake adopts a horizontal injector. The burner with this structure has the following disadvantages: the entire burner is bulky and takes up a lot of space; and the primary air required for combustion needs to be extracted from the gas The bottom shell of the stove enters the ejector supply. For the embedded gas stove, it is necessary to open a hole in the cabinet or the stove panel to solve the air supply. This will cause inconvenience to the overall design of the stove and the overall design of the kitchen, and the shape and appearance are not good. beautiful.

Utility model content

In order to overcome the deficiencies of the prior art, the utility model provides an embedded household gas cooker burner with multiple nozzles, large flow rate and complete upward air intake with independent adjustment of inner and outer nozzles and uniform combustion.
