Completely-premixed intelligent cooking utensil

Abstract

The invention discloses a completely-premixed intelligent cooking utensil, which comprises a combined metal-sheet spraying cooking range, an integral metal hearth and a burning intelligent controller; the cooking range comprises an outer shell, an air inlet pipe, an inner cavity tube and a metal sheet group which is formed by superimposing at least two metal sheets, wherein the upper part of the air inlet pipe is connected with a turbine air mixing plate, the inner wall of the inner cavity tube forms an inner mixing cavity with a base and the turbine air mixing plate, and the outer wall of the inner cavity tube forms an outer mixing cavity with the outer shell and the metal sheet group. The intelligent burning controller comprises a box body, a controller which is arranged inside the box body, an ignition device which is arranged inside the box body, an ignition needle which is connected with the ignition device and a flame sensing needle which is used for detecting whether the ignition needle is fired or not; an electromagnetic proportional valve is arranged inside the box body, and a gas inlet of the electromagnetic proportional valve is connected with an external gas outlet; an air mixer is connected with an outlet of the electromagnetic proportional valve; an air inlet of the air mixer is connected with a direct-current brushless fan which is arranged inside the box body; and an outlet of the air mixer is connected with the lower part of the air inlet pipe.

Description

technical field [0001] The invention relates to a fully premixed intelligent cooker, in particular to an intelligent energy-saving commercial cooker suitable for Chinese food frying stoves. Background technique [0002] The combustion of gas requires air to support combustion, and the mixing ratio and mixing degree of gas and air determine the degree of combustion of gas. When the mixing ratio of air and gas is optimal, the combustion of gas is the most complete, the combustion is the most complete, the calorific value produced is also the highest, and the waste gas and harmful gas produced after combustion are also the least, so as to achieve high efficiency, energy saving and environmental protection the goal of. All kinds of commercial Chinese cooking stoves currently on the market generally have a single function, and mainly adopt blast combustion, which has many disadvantages: 1. The combustion mode is post-mixed combustion, that is, while the gas is burning in the fur...

Problems solved by technology

All kinds of commercial Chinese cooking stoves currently on the market generally have a single function, and mainly adopt blast combustion, which has many disadvantages: 1. The combustion mode is post-mixed combustion, that is, while the gas is burning in the furnace, it is mixed with the air. Mixing, the air-fuel ratio cannot be guaranteed, which will inevitably cause part of the gas to be discharged from the flue without fully burning, the thermal efficiency is low and the flame temperature is low, and a lot of energy is wasted; 2. Due to insufficient combustion, a large amount of gas is generated. CO, NO X Waiting for exhaust gas, serious pollution; 3. Since the post-mixing type is open combustion, the fire takes advantage of the wind to generate a lot of noise and serious heat loss
