Description
Technical field
The present invention relates to gas-cooker parts technical field more particularly to a kind of notch-cut type outer fire covers and burner.
Background technique
Outer fire cover is the common part of gas-cooker, its fire hole of common outer fire cover be mostly round fire hole, grooving fire hole or
The combination of the two.Notch-cut type fire cover on the market is mostly that protrusion is arranged in upper surface, is then equipped with recess portion in corresponding position, then
Make grooving through protrusion and recess portion, forms notch-cut type fire hole.
Chinese patent if a notification number is CN206300196U discloses outside a kind of energy saving gas burner of swirl flame
Fire cover is equipped with several grooving fire holes on the outer fire cover.However, there are following some defects for the technology: 1) being to prevent flame
From flame, close to fire cover wall, this makes flame have side close to fire cover wall for the side of grooving fire hole, cause the face be difficult to supplement it is secondary
Air, flue gas and operating condition are difficult to debug.2) this structure makes flame side be easy to burn fire cover surface, leads to fire cover surface
Temperature increases, it is permanent under be easily deformed, it is not durable enough.3) less fiery slot can only be set, two grooving fire holes are otherwise easily caused
Flame interferes and leads to flue gas height；In addition, less fiery slot can also cause fire hole area insufficient, flame is too long, so as to cause pot
Bracket etc. need to be increased.These can cause performance to be difficult to debug, and the thermal efficiency is low.4) it is easy to block grooving fire because soup is excessive
Hole causes user to take normal cleaning, poor user experience.
Summary of the invention
Aiming at the problems existing in the prior art, the purpose of the present invention is to provide one kind convenient for supplement auxiliary air and
It avoids excessive soup from blocking grooving fire hole or flows through the notch-cut type outer fire cover in burner.
The present invention also provides a kind of burners with above-mentioned notch-cut type outer fire cover.
To achieve the above objectives, the present invention adopts the following technical scheme that.
