an atmospheric cooker

Abstract

The invention discloses a novel atmosphere type cooking stove. The novel atmosphere type cooking stove comprises a panel, a stove body and a grate, wherein the stove body comprises a burner, an inner burner cap and an outer burner cap; a plurality of vent holes are annularly formed in the side direction of the burner; a heat collecting hood is arranged at the upper end of the grate; an interval distance is kept between the heat collecting hood and the grate, so as to allow an air passage to be defined between the heat collecting hood and the panel; the air passage can be communicated to the space between the inner burner cap and the outer burner cap through the vent holes, so as to form an air supplementary passage; the air can be fed to the space between the inner burner cap and the outer burner cap through the air supplementary passage at the lower part of the heat collecting hood; through holes formed in the lower end of the heat collecting hood is matched with the burner to close the air passage between the upper part of the heat collecting hood and the outer side of the outer burner cap and disconnect the air passage outside the outer burner cap, so as to avoid the situation that the supplemented air enters from the outside of the outer burner cap to cause diffusion of flame, force the secondary air to be fed to the space between the inner burner cap and the outer burner cap from the lower part of the heat collecting hood, ensure concentration of the fire, so as to realize high efficient combustion of fuel gas, and improve the heat efficiency.

Description

technical field [0001] The invention relates to an atmospheric combustion embedded household gas cooker. Background technique [0002] Atmospheric combustion built-in household gas stoves are popular with consumers for their large and concentrated firepower, but how to improve the thermal efficiency of products has always been the focus of the industry and consumers. [0003] According to the airflow direction of the fire hole on the outer ring of the gas stove, the gas stove can be roughly divided into three types: inner fireworks, outer fireworks and two-way fire. According to the existing data, the thermal efficiency of the inner firework gas cooker is relatively high. The main reason is that when the flame of the outer ring fire cover is sprayed inward, it can heat the bottom of the cooker, which is equivalent to increasing the heating area. [0004] From the analysis of the structure of the gas stove, there is still room for improvement in the thermal efficiency of the...

Problems solved by technology

[0006] It can be seen from this that the internal pyrotechnic burner with the outer flame structure burner, because the secondary air supply between the inner and outer ring fire covers is less, in fact the secondary combustion of gas is still between the outer ring fire covers In addition, most of the chemical reaction heat is distributed in the area outside the outer ring fire cover, which is not much different from ordinary outer fireworks cookers, and the design idea that the inner fireworks heat is gathered in the center of the burner has not been fully realized, so it is difficult to achieve a large thermal efficiency.
