Description

Combustor and gas stove

Technical Field

The utility model relates to the technical field of kitchen electricity, in particular to a combustor and a gas stove.

Background

At present, consumers attach more and more importance to whether a gas stove is clean, so that a toughened glass panel, an upward convex liquid containing disc and the gas stove of a split burner occupy the main stream, and the gas stove adopting the split burner is characterized in that an inner ring air passage and an outer ring air passage of a burner are assembled on the same ring, so that an ignition needle and an induction needle are required to be arranged outside the outer ring air passage of the burner, but the induction needle is required to be controlled by an inner ring fire to ensure that the burner burns with a small fire, and the induction needle can sense flame so as to ensure that the burner does not flameout.

Based on the above situation, the following three structures are generally adopted in the market at present to solve the above problems;

first, adopt and pass the fire response through the mode of inlaying the copper billet above the distributor to drilling the grooving above the copper billet, this kind of structural style has following two shortcoming: firstly, the cost of inlaid copper blocks is high, and the manufacturing process is complex; secondly, the fire transfer groove is exposed above and is not shielded, when the soup overflows from the bottom of the pot, the fire transfer groove is easy to be blocked, so that flame cannot be sensed, and flameout protection is started.

Secondly, the induction needle is obliquely installed in a mode that a hole for installing the thermocouple is processed into an inclined hole on the furnace end, so that the induction needle head can extend to a position where the fire hole of the inner fire cover is burnt. This solution also has the following three drawbacks: firstly, the manufacturing difficulty of the inclined hole is high; second, it is aesthetically undesirable; thirdly, the assembly and disassembly of the firearm is difficult when cleaning;

thirdly, the diameter of the inner fire cover is increased, so that the fire hole of the inner fire cover can burn to the induction needle during combustion; however, this solution results in a large inner fire cover diameter, and thus has three disadvantages: firstly, the diameter of the inner fire cover is large, and the inner fire cover is not matched with the outer fire cover, so that the appearance is influenced; secondly, the inner ring fire overflows, so that the temperature distribution of the bottom of the pan is uneven, and the cooking effect is affected; third,: the fire cover has large diameter, more consumables and high cost;

with the continuous improvement of the safety performance of the gas cooker, when a dry burning prevention temperature sensor needs to be added in the middle of the burner, the result is that the installation position of the induction needle is more and more outside, and the defects of the three schemes are more and more obvious.

Accordingly, a combustor is needed to solve the above problems.
