Embodiment Construction

[0021]With reference to FIGS. 2-8, in a preferred embodiment, the present invention includes a housing 20, a base 30, a burner 40, a plurality of support members 22, a glass tube 60, and a cover 50.

[0022]The housing 20 has an inside space 21 for installing a gas barrel (not shown). The base 30 is mounted on the housing 20 and has a gas intake tube 44 and a gas control switch 45. The burner 40 is mounted on the base 30 and has a lighting device 47 arranged at a side edge thereof. The support members 22 have a bottom end fixed on the housing 20 to define a mounted space 23 therein. The glass tube 60 is disposed in the mounted space 23; the glass tube 60 may be made of quartz glass which is heat-resistant. In this embodiment, the present invention further includes a plurality of protective wire meshes 25 fixed between the support members 22 to avoid contacting the glass tube 60 with high-temperature.

[0023]The burner 40 includes a top surface extending to define a gas distribution room ...

Abstract

A combustion device for outdoor flame heaters includes an improved structure of a burner disposed below a glass tube thereof. The burner has a gas distribution room therein and a plurality of flame holes at a top surface thereof communicating with the gas distribution room and directed towards the glass tube. The flame holes have a diameter which is at least 10 mm for the flame to be in red and yellow, and a piece of metal wire mesh with a sieve size between 20-30 mesh abuts thereto from under in the gas distribution room, so as to construct a structure with a relatively greater diameter above and a relatively lesser diameter below for the flame to be emitted from the glass tube at an appropriate height by chimney effect to enhance the heating effects.

Description

[0001]This patent application is a continuation-in-part of Ser. No. 13 / 860,683 filed on Apr. 11, 2013, currently pending.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The invention relates to an outdoor flame heater, particularly to one that has an improved burner disposed below a glass tube to enhance combustion efficiency with easy maintenance and more safety.[0004]2. Description of the Related Art[0005]With reference to FIGS. 1A-1C, the US Patent Publication No. 2010 / 0236544 A1 discloses an outdoor flame heater 100 including a bottom housing 10 composed of a set of four lower support members 11, a set of four panels 12, and other relative members for installing a gas barrel (not shown); a control box 13 releasing a flame F to a gas flame outlet 141 of a base 14 on a top of control box 13; a set of four upper support members 15 together with a plurality of protection guards 16 forming a space for installing a glass tube 17; and a reflector 19 mounted onto a dampe...
