Stove core structure of infrared gas stove

Abstract

A stove core structure of an infrared gas stove is provided, including a bottom cover having a receiving groove, a bottom portion of the receiving groove having a gas through hole for guiding gas into the receiving groove, a guiding plate received in the receiving groove, being elevated, the bottom portion and the guiding plate having a space therebetween, a gap which is arranged around a circumferential side of the guiding plate and for the gas to pass therethrough serves as a main gas flow line. The gas flows through the circumferential and out from the infrared ceramic piece assembled on an opening of the receiving groove so that the gas contacts the air around the infrared ceramic piece fully and is combusted completely so as to prevent monoxide poisoning and waste of gas and to elevate a thermal efficiency.

What is claimed is: 
     
         1 . A stove core structure of an infrared gas stove, including:
 a bottom cover, the bottom cover having a receiving groove, a bottom portion of the receiving groove having a gas through hole for guiding gas from bottom to top and into the receiving groove, a guiding plate received in the receiving groove, an infrared ceramic piece being disposed above the bottom cover, the infrared ceramic piece being disposed above the guiding plate, the infrared ceramic piece and the guiding plate having a space therebetween; wherein the guiding plate is elevated, and the guiding plate and the bottom portion of the receiving groove of the bottom cover have the space therebetween so that the gas through hole is non-covered; and a gap which is arranged around a circumferential side of the guiding plate and for the gas to pass therethrough serves as a main gas flow line, so after the gas passes through the gas through hole and enters the receiving groove, the gas passes through the space and flows upward through the gap around the circumferential side of the guiding plate.   
     
     
         2 . The stove core structure of the infrared gas stove of  claim 1 , wherein an elevating portion is disposed between the guiding plate and the receiving groove of the bottom cover to form the space between the guiding plate and the bottom portion of the receiving groove of the bottom cover, and an outer diameter of the guiding plate is smaller than an inner diameter of the receiving groove to form the gap which is annular between an outer periphery of the guiding plate and an inner wall of the receiving groove. 
     
     
         3 . The stove core structure of the infrared gas stove of  claim 2 , wherein the elevating portion is formed by at least two hollow tube bodies, the at least two hollow tube bodies are arranged equidistantly corresponding to each other and take a center of the bottom portion of the receiving groove as a circle center, a top end and a bottom end of each said hollow tube body abut against a bottom face of the guiding plate and the bottom portion of the receiving groove, the bottom portion of the receiving groove at least has two first lock holes corresponding to the at least two hollow tube bodies, and each said first lock hole is for a fixing member to be disposed therethrough from bottom to top, through a tube hole of the hollow tube body and a second lock hole which is preset on the guiding plate and be fixedly screwed with a nut. 
     
     
         4 . The stove core structure of the infrared gas stove of  claim 2 , wherein the elevating portion is formed by at least two pillars which extend upward from the bottom portion of the receiving groove of the bottom cover, a top end of the pillar abuts against a bottom face of the guiding plate, and the guiding plate has at least two second lock holes corresponding to the at least two pillars for two fixing members to be disposed therethrough from bottom to top and screwed into third lock holes of the pillars to be fixed therein. 
     
     
         5 . The stove core structure of the infrared gas stove of  claim 2 , wherein the elevating portion is formed by at least two protrusive blocks which extend upward from the bottom portion of the receiving groove of the bottom cover, and an inner edge of a top end of the protrusive block has a recessed step dented for the outer periphery of the guiding plate to be stuck on the recessed step. 
     
     
         6 . The stove core structure of the infrared gas stove of  claim 2 , wherein the elevating portion is formed by at least one elastic piece, the elastic piece is connected to a bottom face of the guiding plate, two sides of the elastic piece are bent downward to form two elastic props, and a wall of the receiving groove of the bottom cover has at least two restricting grooves corresponding to the two elastic props for the elastic props to be fixedly engaged therewith. 
     
     
         7 . The stove core structure of the infrared gas stove of  claim 2 , wherein the elevating portion is formed by an elastic support which is formed through the circumferential side of the guiding plate being pressed downward, and a wall of the receiving groove of the bottom cover has a restricting groove corresponding to the elastic support for the elastic support to be fixedly engaged therewith. 
     
     
         8 . The stove core structure of the infrared gas stove of  claim 2 , wherein the elevating portion is at least an elastic member, a top end of the elastic member is assembled on a bottom face of the guiding plate, and a bottom end of the elastic member abuts against the bottom portion of the receiving groove of the bottom cover. 
     
     
         9 . The stove core structure of the infrared gas stove of  claim 1 , wherein the guiding plate has a plurality of pores which are for the gas to pass therethrough. 
     
     
         10 . The stove core structure of the infrared gas stove of  claim 1 , wherein an outer diameter of the guiding plate is close to a greatest inner diameter of the receiving groove, the circumferential side of the guiding plate is engaged with a wall of the receiving groove of the bottom cover, an outer ring area of the guiding plate has a plurality of slots for the gas to flow therethrough, the slots are distributed equidistantly to form the gap around the circumferential side of the guiding plate to serve as the main gas flow line.
