Detailed Description

The present invention is illustrated by the following examples, but the present invention is not limited to these examples. Modifications to the embodiments of the invention or equivalent substitutions of parts of technical features without departing from the spirit of the invention are intended to be covered by the scope of the claims of the invention.

The hot hole that explains especially, current honeycomb heat-generating body or combustion plate is vertical arrangement, and the air-fuel mixture burns in the upper end of hot hole for the face that generates heat is located the top of product, consequently, current honeycomb heat-generating body or combustion plate have a pain point in the user use: the cleaning is not good, and overflowing residues fall onto fire holes to block the holes during cooking, so that a small amount of residues still exist even if the residues are carbonized.

The embodiment provides a vertical honeycomb heating element, wherein the vertical heating element refers to that the heating surface of the honeycomb heating element is the inner wall surface or the outer wall surface of the radial direction of the honeycomb heating element, and the heating surface is vertically arranged to ensure that overflowing residues cannot fall onto fire holes to block the fire holes.

Example 1

Referring to fig. 1 to 2, the present embodiment provides a vertical honeycomb heating body, which includes an annular honeycomb body 1 and a plurality of fire holes 2, wherein the annular honeycomb body 1 has a central through hole 11 arranged vertically.
