Abstract:
1. A gas heater, comprising a support unit defining an upper end and a lower end; a burner unit supported by the support unit arranged for heat generation; a venting unit connected to said burner; and a flame guider supported by said support unit and received in said burner, wherein said burner unit comprises: an ignition unit provided on the upper end of said support unit; a transparent radiant unit having an elongated hollow structure defining a radiant unit cavity and a center axis arranged for providing a radiant heating effect, wherein a first end of said radiant unit is operatively communicatd with said ignition unit while connecting to said upper end of said support unit, wherein a second end of said radiant unit is connected to said venting unit in an air-tight manner; a heat reflector coaxially aligned with and connected to said radiant unit through a second end of said radiant unit at said center axis in such a manner that said heat reflector is peripherally and transversely extended outward from said radiant unit at said second end without blocking a top opening of said radiant unit at said second end; and a burner top cover coaxially connected between said heat reflector and said venting unit in such a manner that said venting unit is opened to said radiant unit cavity by said top opening of said radiant unit without blockage of said burner top cover and said heat reflector is covered by said burner top cover, wherein said radiant unit further comprises a bottom unit at said first end of said radiant unit, wherein said bottom unit has a plurality of inlet air passage peripherally provided on said bottom unit such that air circulation is guided to flow from said inlet air passage into said radiant cavity and exit through said venting unit, wherein said flame guider is securely positioned inside said radiant unit cavity of said radiant unit, arranged for guiding and forming a flame pattern inside said radiant unit cavity which is visible through said transparent radiant unit, wherein said flame guider comprises a plurality of flame guider members through which a plurality of guider through-holes are provided thereon and a preset structure of said flame guider is defined; a longitudinal guider support longitudinally supporting said plurality of flame guider members to extended between said first end and said second end of said radiant unit inside said radiant unit cavity; and a bottom support anchoring said longitudinal guider support onto said upper end of said support unit and supporting said plurality of flame guider members, thereby the air circulation which is guided into said radiant cavity is further guided to flow through said flame guider before exiting through said venting unit such that the flame pattern is well-defined and formed through said flame guider and is visible through said transparent radiant unit, wherein said venting unit comprises a vent channel unit defining a vent opening, and a vent cover connected to said vent channel unit for selectively covering said vent opening in such a manner that said vent opening is capable of being completely covered and is capable of being open respectively, wherein said vent channel unit is connected to said second end of said
