Dual-layer energy gathering hood of gas cooker combustor

Abstract

The invention relates to a dual-layer energy gathering hood of a gas cooker combustor, and belongs to the field of gas cookers. The dual-layer energy gathering hood comprises a second energy gatheringhood and is characterized by further comprising a first energy gathering hood, the first energy gathering hood is placed on the second energy gathering hood, an outer ring fire secondary air supplementing channel for supplementing secondary air to the outer ring fire is formed between the first energy gathering hood and the second energy gathering hood, an inner ring fire secondary air supplementing channel for supplementing secondary air to the inner ring fire is formed between the second energy gathering hood and a cooker panel, through the outer ring fire secondary air supplementing channel, the secondary air is supplemented to the outer ring fire, the secondary air is supplemented to the inner ring fire through the inner ring fire secondary air supplementing channel, gas is sufficiently combusted, and CO concentration standard exceeding in the smoke can be avoided.

Description

technical field [0001] The invention relates to a double-layer energy-gathering cover for a burner of a gas cooker, belonging to the field of gas cookers. Background technique [0002] When gas cookers are in use, energy-gathering hoods are installed to reduce heat loss. At present, most energy-gathering hoods are arranged in a single-layer structure, and the heat loss of energy-gathering hoods with a single-layer structure is large. In view of this, the application number is The patent document of 201611247951.4 discloses an energy-gathering component of a gas stove. Although the energy-gathering component in the above-mentioned reference document is double-layered, it also has the following defects: the double-layer energy-gathering cover only has combustion smoke mixed with secondary air to supply air One channel, there is not enough secondary air supply channel for the outer ring flame and the inner ring flame, the secondary air supply is less, the gas combustion is not ...

Problems solved by technology

[0002] When gas cookers are in use, energy-gathering hoods are installed to reduce heat loss. At present, most energy-gathering hoods are arranged in a single-layer structure, and the heat loss of energy-gathering hoods with a single-layer structure is large. In view of this, the application number is The patent literature of 201611247951.4 discloses an energy-gathering component of a gas stove. Although the energy-gathering component in the above-mentioned reference document is double-layered, it also has the following defects: the double-layer energy-gathering cover only has combustion smoke mixed with secondary air to supply air One channel, there is not enough secondary air supply channel for the outer ring flame and the inner ring flame, the secondary air supply is less, the gas combustion is not sufficient, and the channel is inclined downward to form an angle with the horizontal direction, the air intake resistance is relatively large, At the same time, the secondary air is easily heated by the first layer of energy-concentrating cover, causing the oxygen content to drop, which is not conducive to the supplement of secondary air

The energy-gathering cover in the comparison document lacks a liquid receiving device. When the liquid in the pot overflows, it is easy to extinguish the fire and cause danger.
