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. The three-ring fire burner comprises a gas dividing base, wherein an outer-ring fire cover and an inner-ring fire cover are sequentially arranged on the top of the gas dividing base from outside to inside; a plurality of fire holes are formed in the the inner side of theouter-ring fire cover; a fire groove is formed among the fire holes; the gas outgoing directions of the fire holes and the fire groove point to a central area of the burner; a water receiving tray isarranged at the bottom of the gas dividing base; and an injection tube is arranged at the bottom of the water receiving tray. According to the three-ring fire burner and the gas stove disclosed by the invention, through arrangement of the fire holes and the fire groove pointing to the central area of the burner, heat-gathering burning can be carried out, so that the heating efficiency is improved, and the heat loss is reduced; through arrangement of a second fire outlet hole and a third fire outlet hole, the area of fire outlet holes can be increased; and through arrangement of partitioning plates, a structure of the inner-ring fire cover is more compact, and the size of the top part of the burner can be reduced, so that the heat exchanging time between a pot bottom and flame is extended,the heat exchanging area is increased, the heat efficiency of the gas 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
