[Prior Art] A conventional gas furnace, as shown in Fig. 1, includes a casing 91, a t 92 and an intake pipe 93. The outer casing 91 is adapted to receive the core 92 and the rolling mill 93. One end of the core 92 forms a mouth 94 which protrudes from the outer casing 91. The nozzle 94 releases gas for combustion to generate a fire. The intake pipe 93 is connected to the other end of the core 92 for introducing gas, and the intake pipe 93 extends from one side of the casing 91 to connect the gas cylinder or the natural gas line. However, as shown in FIG. 2, when the fire is in contact with a heating member, the gas discharged from the nozzle 94 is easily broken by the stop of the member to be heated, thereby causing heating efficiency of the furnace. reduce. Therefore, there is another conventional gas stove to improve this problem. Another conventional gas burner is further provided with a guide seat placed above the mouthpiece. The guiding seat is expanded in the direction of the nozzle to form a tapered body having a hollow portion, and the bottom end lip of the guiding seat abuts against the outer periphery of the nozzle. The gas is concentrated by the guiding action of the guiding seat to improve the heating effect of the fire. In general, the above-mentioned conventional gas furnace still has the following disadvantages, for example, because the guide seat is placed on the nozzle, compared with the nozzle of the guide seat where the guide seat is not placed The height is obviously improved, so that the hob on the outer casing also needs to be lifted, which causes inconvenience in use. If the height of the M352648 of the nozzle is lowered, the temperature inside the outer casing is increased, and the internal components of the outer casing are damaged and dangerous. . For the above reasons, it is necessary to further improve the above-mentioned conventional gas furnace. [New content] The main purpose of this creation is to reduce the height of the furnace of the gas furnace, and at the same time to isolate the heat source of the fire to avoid the temperature increase inside the gas furnace, so that the internal components of the gas furnace will not Damage caused by damage. φ The main technical means of this creation is to provide a gas furnace comprising a furnace seat and a casing. The furnace base is provided with a core, an intake pipe and an igniter. The intake pipe is connected between the core and the igniter, and the core has a nozzle. The outer casing is provided with a shell seat, a shell cover, a mask and a heat insulating member. - the housing is provided with an opening 'and the housing is received by the housing; the cover covers the opening of the housing, and the housing is provided with an opening corresponding to one of the nozzles; the mask The casing is disposed in the casing and surrounds the furnace mouth; the heat insulation member is disposed in the casing and between the furnace mouth and the igniter. When the burner releases the gas fire, the heat source of the fire is isolated by the cover and the heat insulation to avoid the temperature increase in the seat. The secondary means of this creation is the storage-type tile (4), in which the side of the shell has a number of venting holes, the venting hole is adjacent to the periphery of the opening for the discharge of heat to keep the air circulation in the salty seat to reduce the shell. The temperature inside the seat [Implementation] In order to make this creation and other purposes, misunderstanding 'the following key words of the abstract _, and with the discussion of the formula', = M352648 is described in detail as follows: Eye reference 3 ® No, the Nisaki touch-operated gas furnace system includes a furnace seat 1 (or one or several depending on demand) and a casing 2. The furnace 1 is for releasing a gas to generate a bonfire, and the casing 2 is for accommodating the furnace 1 while isolating the heat source of the fire. The two furnaces 1 are respectively provided with a core U and an intake pipe 12 - a firearm 13. The core 11 is connected to the intake pipe 12 for introducing the gas into the intake pipe 12, and the core u forms a nozzle 111 at one end of the intake pipe 12 to release the gas. One side of the igniter 13 is connected to the air inlet g 12 'another side combination - the surface of the outer casing 2 is protruded from the surface of the outer casing 2 by using the knob 131 to control the igniter 13 to generate a spark for igniting the furnace The gas released by the nozzle 111 causes a fire to be generated on the nozzle. A guide seat 14 is respectively disposed on the nozzle ln of the two furnace cores, and the W-seat u expands to the nozzle m direction to form a hollow portion of the cone and the bottom of the guide seat 14 The end lip is abutted against the periphery of the mouthpiece (1) to be positioned above the mouth ln. As shown in Fig. 4, the guide bow = 14 is provided with a ring recess 141 and a plurality of fixed bosses 142. The annular recess ώ is formed on the inner circumferential surface of the guiding seat 14 adjacent to the bottom end, and is permeable to the outside air of the guiding seat. The fixing protrusion 142 is coupled to the guiding edge and formed into a fold so that the guiding seat 14 is positioned. Referring to FIG. 3, the outer casing 2 is provided with a shell (four) and a shell and a cover 23 (It can also be selected as one or several with the furnace seat 1) and an L piece 24. The housing 21 is provided with an operation panel 2ΐ, two side plates 212 M352648, an internal space 213, an opening 214 and a plurality of ventilation holes 215. The operation panel 211 is located on one side of the housing 21; the two side panels 212 are respectively connected to the two ends of the operation panel 211 and are located on opposite sides of the housing 21; The seat 1 is located on one side of the housing 21 and communicates with the internal space 213 such that the nozzle ill faces the opening 214. The venting opening 215 is located in the side plate 212 of the housing 2 and adjacent to the periphery of the opening 214 for the hot gas to rise and discharge, so that the internal space 213 maintains air circulation. The cover 22 is placed on the housing 21 and covers the opening 214. The cover 22 has two openings 221 (may also be selected as one or several with the furnace 1), and the two openings 221 are respectively The nozzle 111' corresponding to the core η faces the nozzle 111 toward the opening 221, and the height of the nozzle 111 is lower than the opening 221 of the cover 22. As shown in FIG. 4, the two masks 23 are disposed in the inner space 213 of the housing 21 and surround the nozzle 111. The two masks 23 are preferably coupled to the periphery of the opening 221 and surround the opening. The hole 221 is made of a heat-resistant material, and one side of the mask 23 is extended toward the inner space 213 of the housing 21, so that the nozzle 111 is surrounded by the mask 23 to isolate the hole. The heat source of the fire. As shown in FIG. 3, the heat insulating member 24 is disposed in the inner space 213 of the housing 21, and the heat insulating member 24 is made of a heat-resistant material, which is interposed between the operation panel 211 and the opening 221' The inner side walls of the two side plates 212 are connected at both ends. The heat insulating member 24 is preferably selected as a body extending perpendicularly to the bottom surface of the housing 21 toward the opening 214 and between the nozzle ill and the igniter 13 to block the fire. Heat source. Since the nozzle 1U of the preferred embodiment of the present invention is used to match the M352648 of the guide seat 14 to reduce the height, the cover 23 is surrounded by the nozzle in, and the fire generated by the nozzle 111 is used to heat one. When the member is to be heated, the mask 23 blocks the hot air from directly flowing into the inner space 213 of the housing 21, and prevents the fire from directly heating the air in the inner space 213. The heat insulating member 24 is further used to further block the air convection around the nozzle 1U and the igniter a. In addition, the venting opening 215 of the housing 21 can also keep the gas in the internal space 213 exchanged with the outside, thereby lowering the temperature in the housing 21, which can indeed avoid the igniter 13 because of the housing 21 The temperature is too high to be damaged or even dangerous. Although the present invention has been disclosed in the above preferred embodiments, it is not intended to be used in this creation, and any person skilled in the art can carry out various changes without departing from the spirit of the creation and the above-mentioned realities in the domain of '_ It is a technical model that is protected by this creation.
