Description

Technical Field

[0001] The utility model relates to the technical field of kitchen equipment, in particular to a fire distributor and an upper air inlet burner. Background Art

[0002] For the upper air inlet anti-dry burner, the anti-dry burn sensor installation hole must be located at the center of the ignition distributor, which results in a smaller inner ring ejector tube and a smaller gas mixing chamber, which in turn leads to insufficient inner ring ejector capacity, uneven mixing of gas and air, low thermal efficiency, and high CO emissions in flue gas. If the length of the inner ring ejector tube is extended toward the gas nozzle, the gas nozzle will inevitably move backward, which will inevitably increase the volume of the base and cause the problem of occupying a large space. If the diameter of the inner ring ejector tube is increased, the distance between the ignition distributor and the base will inevitably increase, which will also cause the problem of occupying a large overall space.
