Heat shield for stove and stove using heat shield

Abstract

The invention relates to a heat shield for a stove. The heat shield for the stove comprises an annular shield body and is characterized in that the bottom of the shield body is concave upwards to format least two secondary air replenishing grooves through inside and outside; the bottom of each secondary air replenishing groove is provided with a distributing piece; and each distributing piece comprises two side plates which are vertically arranged at an interval, wherein a first gap is formed between the two side plates, a second gap and a third gap are formed between each of the two side plates and the corresponding secondary air replenishing groove, and a first air replenishing channel, a second air replenishing channel and a third air replenishing channel which are mutually independentare formed. The invention also provides the stove using the heat shield. Compared with the prior art, the heat shield for the stove and the stove using the heat shield have the advantages that the two side plates of each distributing piece can form relatively independent spaces, air forms the three corresponding independent air replenishing channels under the separation effect of the two side plates of each distributing piece, entrainment of hot air flow after combustion and high temperature of a combustor on secondary air in every two side plates is effectively avoided, and the characteristic of higher combustion efficiency is achieved.

Description

technical field [0001] The invention relates to a heat shield for a cooker, and also relates to a cooker using the heat shield for a cooker. Background technique [0002] In order to obtain higher combustion efficiency, most of the existing cooker burners have a supplementary function of secondary air. For example, the utility model patent whose authorized announcement number is CN201348296Y discloses "Household Cooker Burner Fire Cover". There are a number of left-handed or right-handed protrusions on the inner surface relative to its generatrix, and the protrusions extend to the axial lower end surface of the inner ring wall plate, and two adjacent protrusions form a fire groove; the top plate is like an inverted frustum-shaped ring , the top plate has a ring-shaped protrusion, the top surface of the ring-shaped protrusion is inverted conical, and there are several angular grooves on the top surface. One of the angular groove walls has a left-handed round fire hole, or th...

Problems solved by technology

However, the inner ring area of ​​the fire cover requires a large amount of secondary air. When the secondary air flows into the gap, it is easily disturbed by the entrainment of the side fire holes. In the case of insufficient secondary air inflow, the combustion is insufficient and the exhaust gas is discharged. high
