Metal honeycomb heating element for gas stove

Abstract

The invention discloses a metal honeycomb heating element for a gas stove. The metal honeycomb heating element for the gas stove at least comprises a metal strip, a boss set I and a boss set II are alternatively arranged on the metal strip, the metal strip is coiled to form a honeycomb heating element body with a plurality of coil rings, the boss set I and the boss set II are arranged on any two adjacent coil rings respectively, and holes for gas to pass are formed between adjacent coil rings. The boss set I and the boss set II comprise a plurality of bosses, the lower ends of the bosses are sealed, and openings are formed in the upper ends of the bosses. According to the metal honeycomb heating element for the gas stove , the the porosity of the lower end of the honeycomb body is low, gascan pass through the lower end of the honeycomb heating element body with a higher speed, the lower end of the honeycomb heating element body can be better cooled, and thus the purposes that flames are prevented from spreading to the lower end of the honeycomb heating element body, the burning stability is high, and backfire is not likely to occur are achieved; and besides, the porosity of the upper end of the honeycomb heating element body is high, it is beneficial to efficient burning of gas, the heating speed is high, and meanwhile it is beneficial to discharging of burning tail gas.

Description

Technical field

[0001] The present invention relates to the technical field of stoves, and in particular to a metal honeycomb heating element for gas stoves. Background technique

[0002] At present, the heating elements of infrared gas stoves on the market mainly include ceramic honeycomb and metal honeycomb heating elements. Among them, the metal honeycomb heating element is more and more popular with consumers because of its better resistance to cold and heat shock and better texture. Welcome. The metal honeycomb heating element is mostly made of one or more metal thin strips, but the dense metal strip has higher thermal conductivity than loose ceramics, and the heat is easier to move from the honeycomb panel to the lower side. Conduction, resulting in high temperature under the honeycomb panel. For the honeycomb body that is coiled by the metal strip and the pores have a uniform structure up and down, in order to prevent the flame from spreading to the lower side of the hon...
