A gas cooker using a secondary air supplementary channel

Abstract

The invention discloses a gas cooker with novel secondary air supplementing channels. The gas cooker comprises a cooker body which comprises a cooker panel and at least one set of cooker head arranged on the cooker panel, a heat collecting cover higher than the cooker panel is arranged on each cooker head, each secondary air supplementing channel communicated with the bottom of the corresponding cooker head is formed between the corresponding heat collecting cover and the cooker panel, each heat collecting cover is provided with a center hole corresponding to the outer diameter of the outer ring of the corresponding cooker head, each center hole is formed in the outer ring of the corresponding cooker head so that the corresponding secondary air supplementing channel and the upper side of the cooker head can be isolated, air which is secondarily supplemented is directly conveyed to the area within an outer fire cover even though secondary air participating in combustion of fuel gas cannot directly enter the area outside the fire cover, the secondary air can be directly supplemented to the root, jetting out flames, of the fire cover, and therefore the fuel gas can be fast combusted, a high-temperature flue gas field can be formed in the center area of the cooker, and the purposes of efficiently combusting the fuel gas and improving the thermal efficiency of the cooker are achieved.

Description

technical field [0001] The invention relates to a gas cooker, in particular to a gas cooker using a secondary air supplementary channel. Background technique [0002] Atmospheric combustion household gas stoves can be divided into three basic modes: inner fireworks and outer fireworks, or a mixture of the two, according to the ejection direction of the outer ring fire hole. [0003] In the atmospheric combustion stove, the gas combustion is carried out in two steps. The primary air is sucked into the distributor through ejection and fully mixed. The gas-air mixture is ejected from the fire hole of the fire cover and ignited to form an intermediate transition product, releasing a small amount of heat; The intermediate transition product of gas and air reacts chemically with the surrounding air, completes complete combustion, and releases a large amount of heat. [0004] The flame of the inner pyrotechnic stove is sprayed towards the center of the heated pot. Theoretically, t...

Problems solved by technology

Existing heat collecting hoods generally deliver the secondary air to the outside of the burner head. This design is reasonable for ordinary outer pyrotechnic cookers, but for inner pyrotechnic cookers, after the flame is ejected from the fire hole, it is also It is difficult to get enough secondary air supplement, because even if the furnace head is designed with a secondary air channel on the side, due to the large negative pressure, most of the secondary air will directly enter the furnace through the gap between the heat collecting cover and the furnace head It is difficult to replenish the space outside the burner head to the root of the flame inside the outer ring burner head, resulting in that the thermal efficiency advantage of the inner firework cannot be fully utilized.
