A three-ring fire burner and gas stove

Abstract

The invention relates to the technical field of household gas stoves, in particular to a three-ring fire burner and a gas stove, including a gas distribution seat, and the top of the gas distribution seat is sequentially provided with an outer ring fire cover and an inner ring fire cover. There are several fire holes on the inner side of the fire cover, and fire grooves are arranged between the fire holes. The gas outlet direction of the fire holes and fire grooves points to the central area of ​​the burner. Injection tube, in the present invention, by setting the fire hole and the fire groove pointing to the central area of ​​the burner, heat can be collected and burned, the heating efficiency can be improved, and the heat loss can be reduced. By setting the second fire hole and the third fire hole, it can Increase the area of ​​the fire hole. By setting the partition, the structure of the inner ring fire cover can be made more compact, which can reduce the volume of the top of the burner, increase the heat exchange time and heat exchange area between the bottom of the pot and the flame, and improve the efficiency of gas consumption. The thermal efficiency of the stove is improved, and the cost of the burner is reduced.

Description

technical field [0001] The invention relates to the technical field of household gas stoves, in particular to a three-ring fire burner and a gas stove. Background technique [0002] The heat load of a high-power burner is usually 4.5-5kW. At present, the fire types of large-power burners on the market are divided into two-ring fire and three-ring fire. The two-ring fire includes the center fire and the outer ring fire, and the three-ring fire includes the center fire. Fire, Middle Ring of Fire and Outer Ring of Fire. If the heat load of a high-power burner with two ring fires is 5kW, the diameter of the fire cover is usually Φ126-Φ135mm, and the load distribution ratio of the inner and outer ring fires is 0.8kW for the center fire and 4.2kW ​​for the outer ring fire. When the user reduces the load of the outer ring fire to 2.5kw through the knob, the flame of the outer ring fire becomes smaller and shorter, the heat intensity of the fire hole decreases, the distance between...

AI Technical Summary

Problems solved by technology

When the user reduces the load of the outer ring fire to 2.5kw through the knob, the flame of the outer ring fire becomes smaller and shorter, the heat intensity of the fire hole decreases, the distance between the high-temperature flame and the bottom of the pot becomes longer, and the utilization rate of heat energy absorbed by the pot will decrease. At the same time, when the user uses a small pot to cook soup, at the same time, adjust the load of the outer ring fire to a moderate level, because the diameter of the fire cover is large and the diameter of the pot is small, and the heat exchange area between the pot and the flame is small, which is not conducive to the effective heat energy. use

[0003] The high-power burners with three-ring fires on the market usually have three nozzles to provide the gas required for combustion, which is better than the high-power burners with two-ring fires in terms of firepower adjustment. Under the premise of stable combustion, higher thermal load and thermal efficiency are achieved, but there are problems of insufficient firepower and low combustion utilization rate. Therefore, in view of the above current situation, it is urgent to develop a three-ring fire burner and gas stove to To overcome the deficiencies in the current practical application
