Double-pipeline double-pre-aerated energy-collecting stove

Abstract

The invention discloses a gas stove used in a kitchen, in particular to a double-pipeline double-pre-aerated energy-collecting stove. The structure of the stove is as follows: an inlet port of a gas tee joint is communicated with gas; one outlet of the gas tee joint is connected with a big fire nozzle through a big fire gas valve; and a big fire valve is arranged between the gas tee joint and a big fire gas regulating valve. The big fire nozzle is connected with a big fire mixing chamber above which a soft fire mixing chamber is arranged, and a burner is arranged above the soft fire mixing chamber. The other outlet of the gas tee joint is connected with a soft fire nozzle through a soft fire switch and a soft fire gas regulating valve and the soft fire nozzle is connected with the soft fire mixing chamber. The big fire mixing chamber is connected through a big fire air valve of which the other end is connected with the soft fire nozzle through an air tee joint and a soft fire air valve, and the other end of the air tee joint is connected with a draught fan. The stove adopts the manners of double pipelines, double air channels and double lines for pre-aerating for a plurality of times, so the big fire gas and the soft fire gas can get sufficient oxygen and can be fully pre-aerated in the respective mixing chambers. Therefore, sufficient burning can be ensured, the gas is saved, and when the big fire and the soft fire burn at the same time, problems of red flame and black fume can be avoided.

Description

technical field [0001] The invention relates to a kitchen gas cooker, in particular to a double-pipe double premixed energy-gathering cooker. Background technique [0002] The energy-concentrating cooker adopts the fully premixed internal combustion technology, which sucks all the air needed for combustion into the premix chamber through ejection, so that the gas and the oxygen in the air are completely mixed once, and in a relatively closed state Combustion can release all the heat in a concentrated manner, with high thermal efficiency. Existing energy-concentrating stoves also have some deficiencies, mainly because gas and air are not evenly mixed, which easily produces prosperous gas, resulting in insufficient combustion. Existing energy-concentrating stoves introduce gas into the stove through a single tube. The top of the single tube is a small fire nozzle, and the bottom of the small fire nozzle is a large fire nozzle. The fan enters air from below. This can only solv...
