Vertical honeycomb heating body

Abstract

The invention discloses a vertical honeycomb heating body which comprises a plurality of annular belt materials which are sequentially overlapped in the vertical direction, a plurality of fire holes which are arranged at intervals in the circumferential direction are formed in the annular belt materials and / or between the adjacent annular belt materials, and each fire hole is horizontally arranged or obliquely arranged in the vertical direction. The vertical honeycomb heating body is simple in structure, has the advantages of being good in anti-dirt performance, reliable in ignition induction and the like, ensures that overflowing liquid or food residues are not prone to falling onto the fire holes during cooking, and is light in weight, high in porosity, more sufficient in combustion and higher in heat efficiency.

Description

technical field [0001] The invention relates to the technical field of cookers, in particular to a vertical honeycomb heating element. Background technique [0002] Infrared stoves are popular in the market because of their better heating uniformity during cooking, lower CO emissions in the exhaust gas, and higher thermal efficiency. There are thousands of fire holes on the core component of the honeycomb heating element, and the air-fuel mixture The gas burns in the fire hole to make the hole wall heat up and turn red, and emit infrared rays to heat the pot. [0003] However, the honeycomb heating element has too many fire holes, and the heating surface of the honeycomb heating element is its top surface. The overflow or food residue during cooking will fall on the fire holes, and some of them will be quickly vaporized or carbonized, but there will be a small amount. The residue may block the fire holes of the honeycomb body, which is not easy to clean, and it will also ca...

Problems solved by technology

[0003] However, the honeycomb heating element has too many fire holes, and the heating surface of the honeycomb heating element is its top surface. The overflow or food residue during cooking will fall on the fire holes, and some of them will be quickly vaporized or carbonized, but there will be a small amount. The residue may block the fire holes of the honeycomb body, which is not easy to clean, and it will also cause some fire holes to burn abnormally

If the overflow or residue falls on the ignition sensing area and blocks the fire hole, it is easy to cause poor ignition and poor induction, which will affect the user experience

[0004] The honeycomb body manufactured in one piece is limited by the material and process, and the entity between the holes is thicker, so it is difficult to manufacture the honeycomb body below 0.3mm in one piece

In addition, the honeycomb body with a thicker wall not only has a heavier product quality, but also has a slower fire response speed, resulting in a poor cooking experience for users, and it will also cause low porosity, which limits the ejection of the nozzle, and the heating surface The non-heating surface conducts more heat, and the combustion efficiency is not high
