Embedded burner of household gas cooker with multiple nozzles, high flow rate and full upward air intake

Abstract

The invention discloses an embedded burner of a household gas cooker with multiple nozzles, high flow rate and full upward air intake. The burner comprises a bottom cup assembly, an inner-outer ring burner head, an outer ring fire distributor cover, and an inner ring fire distributor cover; the inner-outer ring burner and the outer ring fire distributor cover form an outer ring fire chamber and an outer ring fire hole which is communicated with the outer ring fire chamber, and the inner-outer ring burner head and the inner ring fire distributor cover form an inner ring fire chamber and an inner ring fire hole which is communicated with the inner ring fire chamber; the bottom cup assembly is equipped with an inner ring air channel and an outer ring air channel which are communicated with the outside, and the bottom cup assembly is further equipped with an inner ring fire induction tunnel and a plurality of outer ring fire induction tunnels, an inner fire nozzle and a plurality of outer ring fire nozzles which are horizontally arranged; mixed gas outlets of the outer ring fire induction tunnels are communicated with the outer ring fire chamber, and the mixed gas outlets of the inner ring fire induction tunnel is communicated with the inner ring fire chamber. The burner realizes independent regulation of the inner fire and the outer fire, and the full upward air intake, and has the advantages of high heat flow, stable gas supply, thorough burning and high burning power. The burner has larger fire holes for burning, which facilitates to change into different fuel gases.

Description

technical field [0001] The invention 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 [0002] 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 combustio...

Problems solved by technology

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
