Problems solved by technology

[0002] Due to the heat load requirements of the existing upper air intake burners of gas cookers, two injection pipes and corresponding nozzles are generally provided to supply gas to the main fire and the center fire of the burner respectively. The left and right are arranged together, so they cause mutual interference when the air is induced, and the ejection effect is poor, resulting in insufficient primary air intake, insufficient gas combustion, low combustion efficiency and not environmentally friendly, and the nozzle of the stove is usually installed on the valve body or other Installed on the components instead of the burner, the accumulation of processing and installation errors of each component leads to the misalignment between the nozzle and the injection pipe, which also causes poor injection effect
The injection tube and the fire distributor of the burner are generally integral continuous casting structures. During the working process, the temperature of the injection tube will increase with the temperature of the fire distributor, resulting in poor injection effect and unstable operation of the burner. As the temperature of the injection tube increases, the possibility of burner flashback will increase, causing potential safety hazards

Embodiment 1

[0019] Example 1, such as figure 1 As shown in FIG. 1 , an upper air intake burner for a gas cooker includes a burner support, a fire distribution seat and a fire cover. Such as figure 2 As shown, the burner support includes a lower seat 11 and an upper cover 12, and the lower seat 11 and the upper cover 12 are fastened by screws, and an outer ring fire venturi ejector tube 13 and a central fire venturi ejector tube 13 propelled from the outside to the inside are formed inside. Fire Venturi ejector tube 14, outer ring fire Venturi ejector tube 13 and center fire Venturi ejector tube 14 are arranged in opposite directions, and there are two primary air intake holes 15 opening upwards on the edge of the burner support. The air inlet hole 15 is correspondingly communicated with the mouth of the outer ring fire Venturi injection pipe 13 and the central fire Venturi injection pipe 14, and the gas nozzle 16 is installed on the burner support through the nozzle seat 17. The gas noz...

Embodiment 2

[0025] Example 2, such as Figure 4 The difference between the present embodiment shown and the previous example is that four Venturi ejector tubes and corresponding four gas nozzles 16 and four primary air intake holes 15 are distributed in the burner support, one of which is the center Fire Venturi ejector tube 14, the other three are outer ring fire Venturi ejector tubes 13. The central fire Venturi ejector tube 14 communicates with the central fire distribution chamber of the central fire seat 32 through two central fire air guide tubes 22, and the three outer ring fire Venturi ejector tubes 13 communicate with the outer ring distributor through three outer ring fire air guide tubes 21. The fire distribution cavity of the fire seat 32 adopts a multi-injection system, and the primary air is sufficient, which can realize full combustion of gas and increase the thermal load of the burner.

[0026] The burner of the present invention is embedded on the cooker panel through it...

Abstract

The invention relates to a top-intake burner of a gas cooker. The top-intake burner comprises a burner support, a fire distribution seat and fire caps. The top-intake burner is characterized in that the burner support is combined by an lower support and an upper cover, at least two Venturi ejector pipes are formed, the openings of the Venturi ejector pipes are correspondingly communicated with primary air inlets with an upward opening, a single gas nozzle is mounted in the primary air correspondingly and is disposed right against the center of one of the the Venturi ejector pipes, the other end of the gas nozzle is communicated with a gas inlet pipe, one Venturi ejector pipe is communicated with a fire distribution chamber of the fire distribution seat through one gas guide pipe or multiple gas guide pipes, and an air passage is reserved between the upper cover of the burner support and the fire distribution seat. The top-intake burner is reasonable in structural design, efficient and energy saving, is capable of realizing precision supply of primary and secondary air and complete and stable burning of the gas, and is especially suitable for embedded household gas stoves.

Description

technical field [0001] The invention relates to a burner for a gas cooker, in particular to an upper air intake burner for an embedded gas cooker. Background technique [0002] Due to the heat load requirements of the existing upper air intake burners of gas cookers, two injection pipes and corresponding nozzles are generally provided to supply gas to the main fire and the center fire of the burner respectively. The left and right are arranged together, so they cause mutual interference when the air is induced, and the ejection effect is poor, resulting in insufficient primary air intake, insufficient gas combustion, low combustion efficiency and not environmentally friendly, and the nozzle of the stove is usually installed on the valve body or other The components are not installed on the burner, and the accumulation of processing and installation errors of each component leads to the misalignment between the nozzle and the injection pipe, which also causes poor injection e...
