TECHNICAL FIELD [0001] The present invention relates to a gas combustion device for generating completely burnt hot air or warm air with high combustion efficiency using burning flame caused by, in particular, Liquefied Petroleum Gas (LPG) as a heat source. BACKGROUND ART [0002] Conventionally, a gas combustion device contained in devices such as portable hair driers and heat guns has been known. [0003] In a gas combustion device contained in a hair drier, for example, a combustor for burning combustion gas (for example, LPG) is provided in a cylindrical casing of the hair drier. The combustor bums the combustion gas supplied from a gas tank as a source for the combustion gas and the air heated in a combustion chamber of the combustor is emitted to the side of a vent by a fan provided at the side of an inlet of the casing. [0004] LPG as combustion gas is supplied from the gas tank to an ejector provided at the combustor. In the ejector, outside air necessary for combustion is sucked and mixed gas which consists of the combustion gas and the sucked air is generated. Thereafter, the mixed gas is injected from a wick (wire mesh) provide at the side of the inlet of the combustor. A spark is blown from an ignition plug (ignitor) to the wick and ignites the mixed gas. [0005] The ignited burning flame burns in the combustion chamber so as to spread outwards from the wick and the combustion gas is discharged from an opened vent for combustion gas at an end ahead of the combustion chamber as warm air (refer to Japanese Patent Application Laid-open Publication No. 2002-233416). [0006] In the conventional gas combustion device, the temperature of the combustion gas generated from the combustor tends to become high at its center part and low at its peripheral part. Especially when the gas combustion device is used for the hair drier or the like, outside air sent from an air-blower such as the fan provided at the hair drier passes laterally to the air heated by the combustor, causing the problem that the temperature of warm air at the center part becomes higher and the temperature of warm air at the peripheral part becomes lower. [0007] Furthermore, when a large amount of the combustion gas is generated from the combustor, hot combustion gas and burning flame along with the air sent by the fan are easy to directly burst out of the combustor, causing a safety hazard. [0008] To solve the above-mentioned problem, the present invention intends to provide a gas combustion device in which the temperature of warm air of the combustion gas discharged from the combustor is uniformed and which has high safety by preventing burst-out of burning flame. DISCLOSURE OF THE INVENTION [0009] To achieve the above-mentioned object, a gas combustion device comprises a combustion chamber for burning gas supplied from a gas source therein, a combustion gas vent for discharging combustion gas burnt in the combustion chamber, and a baffle member for adjusting distribution the combustion gas discharged from the combustion gas vent which is arranged at the combustion gas vent. BRIEF DESCRIPTION OF THE DRAWINGS [0010] FIG. 1 is a sectional view of a gas combustion device in accordance with an embodiment of the present invention taken along a line I-I in FIG. 2. [0011] FIG. 2 is a front view of the gas combustion device viewed from the left side in FIG. 4. [0012] FIG. 3A is a plan view of a baffle plate in accordance with the embodiment of the present invention. [0013] FIG. 3B is a side view of the baffle plate in accordance with the embodiment of the present invention. [0014] FIG. 4 is a side view of the gas combustion device in accordance with the embodiment of the present invention. [0015] FIG. 5 is a sectional view taken along a line V-V in FIG. 1. [0016] FIG. 6 is a back view of the gas combustion device viewed from the right side in FIG. 4. BEST MODE FOR CARRYING OUT THE INVENTION [0017] Referring to figures, an embodiment of the present invention will be described below. [0018] With reference to FIG. 1, a gas combustion device 1 in accordance with this embodiment has an ejector 3 for generating mixed gas consisting of LPG, for example, as combustion gas and air, an electrode 5 as an ignitor for igniting the mixed gas generated by the ejector 3 and a combustor 7 for burning the mixed gas ignited by the electrode 5 therein. [0019] Referring to FIGS. 4 to 6, a chamber 9 of the combustor 7 made of aluminum (die-cast) is a substantially cylindrical body with circular right and left side faces in the longitudinal direction of the chamber 7 in this embodiment as shown in FIGS. 5 and 6. The inside of the chamber 9 is comprised of a primary combustion chamber 11 located on the right side in FIG. 1 and a secondary combustion chamber 13 located ahead of the primary combustion chamber 11 (left side in FIG. 1). The ejector 3 is attached to the gas induction side in the rear of the primary combustion chamber 11 (right side in FIG. 1). Continue reading...
