Gas stove with air inlet swirler

Abstract

The invention discloses a gas stove with a gas inlet swirler, and belongs to the field of household kitchen ware. The gas stove comprises a burner inner cavity, a fire cover base, an inner fire cover, an outer fire cover, a gas part, an air part and a mixing part. The gas part comprises a gas inlet, a nozzle and a gas outlet, wherein the air inlet swirler of the air part is coaxially arranged on the peripheral face of the nozzle in a sleeving mode. The air inlet swirler comprises an air inlet swirler inlet, an air inlet swirler blade and an air inlet swirler outlet. The mixing part comprises a contraction pipe section and an expansion pipe section. The large-diameter end of the contraction pipe section coaxially sleeves the air inlet swirler in a sealed manner, and the small-diameter end of the contraction pipe section is connected with the burner inner cavity through the expansion pipe section in a sealed manner. After gas is sprayed out from the gas outlet of the nozzle, air enters the air inlet swirler inlet under the action of injection and becomes swirl air through the air inlet swirler to be premixed with gas, premixed air-gas mixed gas is further evenly mixed in the burner inner cavity and the fire cover base, and finally the gas-air mixed gas is sprayed to a combustion area through a fire outlet hole.

Description

technical field [0001] The invention belongs to the field of household kitchen utensils, and in particular relates to a gas stove with an air inlet cyclone. Background technique [0002] In recent years, gas stoves are an indispensable part of the kitchen, and their energy consumption and flue gas emissions are attracting more and more attention. The energy consumption of gas stoves and CO emissions in flue gas are related to the uniformity of gas and air mixing in the stove. The higher the uniformity of gas and air mixing, the less CO emissions in the flue gas, the higher the thermal efficiency of the gas stove, and the higher the energy efficiency level. Therefore, it is necessary to improve and optimize the air intake scheme of the gas cooker to improve the mixing uniformity of gas and air. [0003] In the prior art, gas and air are introduced into the inner cavity through the injection tube, and the gas and air are mixed while flowing along the injection tube. The util...

Problems solved by technology

However, the installation of partitions in the nozzle increases the flow resistance and slows down the flow velocity, and when entering the mixing chamber of the furnace head, the fuel and air only have axial velocity, and there is no radial and tangential velocity to strengthen the mixing effect, so Insufficient mixing uniformity of gas and air is not conducive to energy saving
