Gas stove capable of controlling multiple gas nozzles in grouping manner

Abstract

A gas stove capable of controlling multiple gas nozzles in a grouping manner comprises a flame control device, which is characterized in that the flame control device has three groups to hundred groups of gas nozzles, wherein at least one group has two to fifty gas nozzles, and the total number of the gas nozzles is four to three hundred. A Gas outflow through hole is arranged on a gas nozzle plate, the gas nozzles are installed on the through hole; a flame adjusting plate is arranged below the gas nozzle plate, a gas storage chamber is arranged below the flame adjusting plate; the flame adjusting plate is installed on a lower surface of the gas nozzle plate through a positioning-and-clamping device; gas-out section adjusting grooves and gas-in section adjusting grooves are arranged on the flame adjusting plate, a gas inflow through hole is arranged on the flame adjusting plate, a gas manifold is installed on the gas nozzle plate and is communicated with the gas inflow through hole; a transmission mechanism can drive the flame adjusting plate to move relatively with the gas nozzle plate in a gapless manner. When flames are adjusted to be small, heights of the flames are not lowered, radiating area of a burner is reduced, and heat efficiency is improved.

Description

technical field [0001] The invention relates to a gas cooker, in particular to a gas cooker which controls a plurality of gas nozzles in groups. Background technique [0002] Existing gas cooker has many shortcomings: the one, thermal efficiency is not high, generally less than 58%, and one of reason is that when turning down heat load, jet speed reduces, and flame becomes shorter, and the distance of flame and pot becomes larger. The second is that the flame arrangement is unreasonable, and the area of ​​about 50 square centimeters in the middle of the bottom of the pot is a low temperature area. The third is that the adjustment range of the heat load is small, and when it is small to a certain extent, it will be tempered and extinguished. To keep the flame of the gas stove in the best state, the jet speed, jet volume, area of ​​the fire hole, area of ​​the fire cover, volume of the mixed gas chamber, etc. need to be adjusted to the optimum value. However, the current gas...

Problems solved by technology

[0002] Existing gas stoves have many disadvantages: the first is that the thermal efficiency is not high, generally less than 58%. One of the reasons is that when the thermal load is turned down, the jet speed decreases, the flame becomes shorter, and the distance between the flame and the pot becomes larger

The second is that the flame layout is unreasonable, and the area of ​​about 50 square centimeters in the middle of the bottom of the pot is a low temperature area.

The third is that the adjustment range of the heat load is small, and when it is small to a certain extent, it will be tempered and extinguished

Although the end face of the ejector tube is higher than the damper, the amount of ejected air can be adjusted, but the flame adjustment is frequent, and no one is willing to adjust the damper frequently. What's more difficult is that ordinary people cannot accurately adjust the damper in a short time
