Description
Technical field
The present invention relates to gas-cooker field more particularly to a kind of external ring fire covers of gas burner.
Background technique
It is provided with main fire hole in the fire cover of gas-cooker, combustion gas and the mixed gas of air are after mixed air cavity mixes through fire output hole
Outflow, is ignited and forms combustion flame.Existing gas burner fire cover, in order to guarantee to stablize burning, not from flame, in fire cover
Certain steady flame structure will be set, and steady flame mode is mostly to have small slot in the main fire hole arranged for interval of fire cover.Such as: application
It number is that the Chinese invention patents of 201410115151.1 (application publication number is 104949170 A of CN) discloses a kind of gas-cooker
Fire cover, be equipped with steady flame slot in its lateral wall in the fire cover, which is connected with several grooves respectively and is formed several
A stable flame hole.The design of stable flame hole is so that fire cover complicated integral structure, difficulty of processing increase, not easy cleaning, when soup etc. occurs
When discharge situation, stable flame hole is easily blocked, and leads to the generation from flame phenomenon.In addition, the reason of occurring from flame phenomenon is single
Air velocity is too fast in fire hole, and flame root temperature is low, the design of stable flame hole in above-mentioned patent, imitates to the buffering of main fire hole air-flow
Fruit is poor, and the lower section of main fire hole is arranged in, the distance apart from main fire hole root farther out, therefore the heating to main fire hole root
It acts on bad.As it can be seen that steady flame structure in the prior art could be improved.
In addition, the main fire hole of existing external ring fire cover is generally circular hole, such as Patent No. ZL201420826134.4 (authorization
Burner structure disclosed in Chinese utility model patent of the notification number for 204513485 U of CN), this kind of main fire hole are using
When generating discharge in the process, if discharge enters in main fire hole, since discharge generally has viscosity, main fire hole can be attached to
Inner wall on, so as to cause main fire hole blocking, bring difficulty to the cleaning of main fire hole.
