An air supply branch pipe is provided.
    [27] In the present invention described above, when burning the burner, fuel gas is supplied by the fuel gas supply means and combustion air is supplied by the air supply / exhaust fan. The inside of the combustion chamber becomes a high temperature state by heat radiation from the burner and heat radiation from the porous body heated by the high temperature combustion exhaust gas of the burner, and heat is released from the side of the combustion chamber.
    [28] However, during operation of the air supply / exhaust fan, air is also supplied into the space formed by the side of the combustion chamber and the outer peripheral wall through the air supply branch in the air supply passage. Therefore, the heat supplied from the side of the combustion chamber by the air supplied into the space is suppressed from propagating into the gas cooker, whereby the gas cooker becomes a high temperature state such as a motor for operating the air supply / exhaust fan. It is possible to prevent the parts from failing due to overheating. According to the first aspect of the present invention, since the fan for supplying air into the space does not need to be provided separately from the air supply / exhaust fan, the cost increase in the gas furnace can be suppressed.
    [29] In the first aspect, the space is formed to be sealed except for the air supply port and the exhaust port, the air supply branch pipe is connected to the supply port, and the outlet port and the air supply / exhaust fan are connected to each other to allow the air outlet port to communicate with each other. Characterized in that the exhaust reflux pipe for refluxing the air discharged from the air supply / exhaust fan.
    [30] According to the present invention described above, the air supplied into the space through the supply port in the air supply branch pipe is heated by heat emitted from the side of the combustion chamber. The heated air is sucked into the air supply / exhaust fan through the exhaust reflux pipe at the outlet of the space and is supplied to the burner through the air supply passage. Therefore, since the combustion air supplied to the burner is heated up, the temperature of the combustion flame of the burner is increased and the combustion speed of the burner is increased, thereby increasing the surface temperature of the burner. Moreover, since the temperature of the combustion exhaust gas of the burner also increases, the radiation conversion efficiency in the porous body through which the combustion exhaust gas passes can be improved.
    [31] In addition, the second aspect of the present invention provides an outer circumferential wall spaced apart from the lateral surface of the combustion chamber so as to form a space sealed by the lateral side and the outer circumferential wall except for the air inlet and the outlet. In addition, the exhaust port and the air supply / exhaust fan is connected in series characterized in that it comprises an exhaust reflux tube for refluxing the air discharged from the outlet to the air supply / exhaust fan.
    [32] According to the present invention described above, the indoor air supplied from the supply port of the space is heated by the heat emitted from the side of the combustion chamber when passing through the space, and is sucked into the air supply / exhaust fan through the exhaust reflux pipe do. Accordingly, as in the first aspect, the temperature of the air supplied to the burner by the air supply / exhaust fan is increased by the air heated in the space, whereby the surface temperature of the burner during combustion can be increased. In addition, it is possible to improve the radiation conversion efficiency in the porous body.
    [33] Moreover, in the 3rd aspect of this invention, the outer peripheral wall is provided around the side surface of the said combustion chamber at intervals with this side surface, and forms the space sealed by the said side surface and the said outer peripheral wall except air supply port and discharge port, The air supply passage is characterized by comprising a first air supply communication pipe for connecting the air outlet of the air supply / exhaust fan and the supply port in series, and a second air supply communication pipe for communicating the space, the discharge port and the burner in series. .
    [34] According to the present invention described above, the heat emitted from the side of the combustion chamber by the air supplied from the first air supply communication tube to the space is suppressed from being propagated into the gas furnace and is heated when passing through the space. Thus, the combustion temperature of the burner and the radiation conversion efficiency in the porous body can be improved by the combustion air supplied to the burner through the second air supply communication tube.
    [35] In addition, the fourth aspect of the present invention provides an outer circumferential wall spaced apart from the lateral surface of the combustion chamber so as to form a space sealed by the lateral side and the outer circumferential wall except for the air inlet and the outlet. Moreover, the said exhaust port is arrange | positioned toward the outer location of the said combustion chamber in the said upper plate, It is characterized by including the cooling air supply means which supplies cooling air from the said supply port to the said space.
    [36] According to the present invention described above, the cooling air supplied into the space from the supply port by the cooling air supply means passes through the space and is discharged from the discharge port toward the outer portion of the combustion chamber in the upper plate. . Therefore, similarly to the first aspect described above, the heat emitted from the side of the combustion chamber by the air passing through the space is suppressed from being propagated into the gas furnace, and the upper plate is discharged by the air discharged from the discharge port. The outer part of the combustion chamber in is cooled. Thereby, heat can propagate to the outer part of the said combustion chamber in the said upper board, and it can prevent that a user feels hot.
    [37] Moreover, the 5th aspect of this invention is characterized by including the cooling air supply means which supplies cooling air to the said combustion chamber.
    [38] According to the present invention described above, the atmospheric temperature in the combustion chamber can be lowered by the air supplied into the combustion chamber by the cooling air supply means. Therefore, the amount of heat propagated to the inside of the gas furnace from the side of the combustion chamber can be reduced, and the top plate can be prevented from becoming overheated, especially when no heated object is placed on the top plate.
    [39] In addition, the heated object placed on the upper plate is mainly heated by the burner and the infrared rays emitted from the porous body, which are transferred to the heated object through the upper plate, so that the decrease in the ambient temperature in the combustion chamber is heated. The effect on heating power to water is minor.
    [40] In the fifth aspect, an outer circumferential wall is provided around the side surface of the combustion chamber at a distance from the side to form a space sealed by the side surface and the outer circumferential wall, excluding air supply and discharge ports. And discharging the outlet port so as to communicate with the combustion chamber toward the lower surface of the upper plate, wherein the cooling air supply means supplies the cooling air to the combustion chamber through the space and the discharge port at the supply port.
    [41] According to the present invention described above, the heat passing from the side of the combustion chamber is suppressed from propagating into the gas furnace by the air passing through the space, and the air supplied from the outlet to the combustion chamber is Since it hits a lower surface directly, the effect which cools the said upper board can be heightened.
    [42] In the fourth or fifth aspect, the cooling air supply means is constituted by an air supply branch pipe branched from the air supply passage.
    [43] According to the present invention described above, since the cooling air is supplied into the space or the combustion chamber by the supply branch pipe, it is not necessary to install a fan for supplying cooling air separately from the supply / exhaust fan. Therefore, the cost rise to a gas furnace can be suppressed.
    [44] Embodiment of the Invention
    [45] EMBODIMENT OF THE INVENTION The 1st-5th embodiment of this invention is described with reference to FIGS.
    [46] 1 is an external view and a configuration diagram of a gas furnace in the first embodiment of the present invention, FIG. 2 is a configuration diagram of the gas furnace in the second and third embodiments of the present invention, and FIG. 4 is a configuration diagram of the gas furnace in the fourth embodiment, and FIG. 4 is a configuration diagram of the gas furnace in the fifth and sixth embodiments of the present invention.
    [47] First, with reference to FIG. 1, 1st Embodiment of this invention is described.
    [48] The gas furnace 1 is located on the upper surface of the combustion chamber 10 (refer FIG. 1 (b)) in which the surface combustion burner 2 and the annular porous body 3 were accommodated, as shown in FIG. By heating the food (heated object) placed on the heat resistant glass upper plate 4 to supply the combustion air to the burner (2), the exhaust gas of the burner (2) is exhausted through the porous body (3). The furnace 26 (refer FIG. 1 (b)) is provided with the air supply / exhaust fan 6 sent to the exhaust port 5, and the combustion amount control switch 7 for adjusting the combustion amount of the burner 2. As shown in FIG. In addition, an outer circumferential wall 9 is provided outside the combustion chamber 10.
    [49] 1 (b) is a cross-sectional view of the gas furnace 1 shown in FIG. 1 (a) seen from the side, and the burner 2 and the porous body 3 are provided in the combustion chamber 10. Then, the combustion gas supplied through the air supply passage 20 by the air supply / exhaust fan 6 and the fuel gas supplied through the nozzle 22 provided at the tip of the gas supply pipe 21 are mixed in the mixing pipe 23. It is mixed and fed to the burner 2. The gas supply pipe 21 is provided with a gas main valve 24 and a gas proportional valve 25 from an upstream side. In addition, the gas supply pipe 21 and the nozzle 22 constitute the fuel gas supply means of the present invention.
    [50] The combustion exhaust gas of the burner 2 is discharged from the exhaust port 5 (see Fig. 1 (a)) through the porous body 3 and the exhaust passage 26 by the air supply / exhaust fan 6. Moreover, the heat insulation space 12 (corresponding to the "space" of the present invention) is formed by the side surface 11 of the combustion chamber 10 and the outer peripheral wall 9 provided at intervals with the side surface 11.
    [51] The heat insulation space 12 is formed to be sealed except for the air inlet 13 and the outlet 14. And the supply port 13 is formed in the lower side of the heat insulation space 12, and is connected through the air supply passage 20 through the air supply branch pipe 15 (equivalent to the "cooling air supply means" of this invention). . Moreover, the discharge port 14 is located outside the combustion chamber 10 in the glass upper plate 4 along the side surface 11 of the combustion chamber 10 above the heat insulation space 12 (FIG. 1 (b), It is formed so that air may be discharge | released toward the part except the inner range of diameter L10 in the inner range of diameter L20.
    [52] Then, the operation of the gas furnace 1 is controlled by the controller 30 composed of a microcomputer or the like. A combustion amount control switch 7 is connected to the controller 30, and the controller 30 controls the combustion operation of the burner 2 in accordance with the operation of the combustion amount control switch 7 by the user.
    [53] Specifically, the controller 30 controls the flow rate of the fuel gas to the burner 2 by adjusting the opening degree of the gas proportional valve 25 in the state in which the gas main valve 24 is opened, while supplying air / The supply flow rate of the combustion air to the burner 2 is controlled by adjusting the rotation speed of the exhaust fan 6.
    [54] During the combustion of the burner 2, the heat 51 at the combustion surface of the burner 2, where the combustion flame 50 of the burner 2 is generated, and the high-temperature combustion exhaust gas of the burner 2 pass through. The food is heated through the glass top plate 4 by the radiant heat 52 in the heated porous body 3.
    [55] At this time, the combustion chamber 10 is brought to a very high temperature (about 1000 ° C.) by the heat 51 in the burner 2 and the radiant heat 52 in the porous body 3, and the side surface of the combustion chamber 10 is maintained. Radiation heat is also released in (11). The side surface 11 of the combustion chamber 10 is formed of sheet metal such as stainless steel, and the inner side (the porous body 3 side) of the side surface 11 is exposed to high temperature by the combustion exhaust gas of the burner 2, Oxidation increases as a result of oxidation.
    [56] However, at the time of burning of the burner 2, a part of combustion air supplied by the air supply / exhaust fan 6 (corresponding to the 'cooling air' of the present invention) is supplied from the air supply passage 20 to the air supply branch pipe ( It is supplied into the heat insulating space 12 via 15, and the air supplied from the supply port 13 of the heat insulating space 12 passes through the heat insulating space 12 and is discharged from the outlet 14.
    [57] Therefore, the heat propagated from the side surface 11 of the combustion chamber 10 is prevented by the air passing through the heat insulating space 12 from propagating into the gas furnace 1, thereby the side surface 11 of the combustion chamber 10. The inside of the gas furnace 1 becomes abnormally high temperature by the heat discharged from the heat sink, and the electronic device substrate or the gas main valve 24, the gas proportional valve 25, the air supply / exhaust fan ( It is possible to prevent an electronic device component such as a fan motor (not shown) of 6) from failing due to overheating.
    [58] In addition, since the outer circumferential wall 9 is prevented from being heated to a high temperature state by the heat insulating effect of the heat insulating space 12 and the air passing through the heat insulating space 12, the oxidation of the outer circumferential wall 9 is prevented. The increase in the emissivity is prevented.
    [59] Moreover, since the air which passed the inside of the heat insulation space 12 is discharged toward the glass upper plate 4 from the discharge port 14, to the location where the said air in the glass upper plate 4 collides (FIG. 1 (b)). In this case, the portion except the inner range of the diameter L10 in the inner range of the diameter L20 is cooled by this air. Therefore, heat propagates to the outer surface of the upper surface of the combustion chamber 10 in the glass upper plate 4 (inner part of the diameter LlO in FIG. 1 (b)) to make the user feel hot or cookware such as a pot. It can suppress that the handle part of the heat becomes hot and cannot be lifted easily.
    [60] In addition, in this 1st Embodiment, although the outlet 14 of the heat insulation space 12 was formed so that it might point to the location of the glass top plate 4 of the outer side of the combustion chamber 10, the outlet of the heat insulation space 12 was changed to another position. Even when formed, the effect of the present invention can be obtained.
    [61] In addition, although the heat insulating space 12 is formed to be sealed except for the air inlet 13 and the outlet 14, the heat insulating space is provided through the air supply branch pipe 15 even when the heat insulating space 12 is not sealed. By supplying air into (12), the effect of this invention can be acquired.
    [62] Subsequently, a second embodiment of the present invention will be described with reference to Fig. 2A.
    [63] In addition, about the structure similar to the gas furnace shown in FIG. 1, the same code | symbol is attached | subjected and the description is abbreviate | omitted.
    [64] In the second embodiment, similarly to the first embodiment described above, the heat insulation space 12 is formed to be sealed except for the air supply port 13 and the discharge port 40, and the supply of the heat insulation space 12 is performed. The air supply branch pipe 15 which connects the sphere 13 and the air supply passage 20 in series is provided. And the exhaust reflux pipe 42 which connects the exhaust port 40 of the heat insulation space 12, and the air intake port 41 of the air supply / exhaust fan 6 in series is provided.
    [65] Therefore, during combustion of the burner 2, the air supplied through the air supply branch pipe 15 is supplied into the heat insulating space 12 from the supply port 13, and the air passing through the heat insulating space 12 is discharged ( 40 is introduced into the air inlet 41 of the air supply / exhaust fan 6 through the exhaust reflux pipe 42.
    [66] In this case, in the air intake port 41 of the air supply / exhaust fan 6, the air heated by the heat emitted from the side surface 11 of the combustion chamber 10 when passing through the adiabatic space 12 is exhausted. ), And the heated air is mixed with indoor air sucked in the air intake port 41 and supplied to the air supply passage 20.
    [67] Therefore, similarly to the first embodiment described above, it is possible to suppress the propagation of heat released from the side surface 11 of the combustion chamber 10 by the air flowing in the heat insulating space 12 into the gas furnace.
    [68] Moreover, since the temperature of the combustion air supplied to the burner 2 becomes high, as a result, the temperature of the combustion flame 50 of the burner 2 rises, and also the combustion speed of the burner 2 increases, When the surface temperature of the burner 2 at the time of combustion rises and the temperature of the combustion exhaust gas discharged | emitted through the porous body 3 also becomes high, the radiation conversion efficiency in the porous body 3 can be improved.
    [69] Subsequently, a third embodiment of the present invention will be described with reference to FIG. 2 (b).
    [70] In addition, the same code | symbol is attached | subjected about the structure same as the gas furnace shown in FIG. 1 and FIG. 2 (a), and the description is abbreviate | omitted.
    [71] In the third embodiment, similarly to the second embodiment, the heat insulation space 12 is formed to be sealed except for the air supply ports 43 (= 43a, 43b) and the discharge port 40, and the heat insulation is performed. An exhaust reflux tube 42 is provided which connects the outlet 40 of the space 12 and the air inlet 41 of the air supply / exhaust fan 6 in series.
    [72] However, the air supply branch pipe 15 (refer FIG. 2 (a)) in 2nd Embodiment mentioned above is not provided, and the supply port 43 is formed so that the lower part of the heat insulation space 12 may be opened. . In this case, air is supplied from the supply port 43 into the heat insulation space 12 by the operation of the air supply / exhaust fan 6, and this air is supplied from the side surface 11 of the combustion chamber 10 when passing through the heat insulation space. After heating by the heat released, it is introduced into the air inlet 41 of the air supply / exhaust fan 6 through the exhaust reflux pipe 42.
    [73] Here, in the above second embodiment, since air is supplied into the heat insulation space 12 through the air supply branch pipe 15, the heated air again passes the heat insulation space 12 when passing through the heat insulation space 12. ), The heat insulation effect by the heat insulation space 12 is slightly reduced.
    [74] In the third embodiment, on the other hand, the indoor air is supplied into the heat insulating space 12 from the supply port 43 in which the indoor air is opened. Accordingly, the combustion air supplied to the burner 2 is heated to increase the combustion temperature of the burner 2 without lowering the heat insulation effect in the heat insulation space 12 and in the porous body 3. The conversion efficiency can be improved.
    [75] Subsequently, a fourth embodiment of the present invention will be described with reference to FIG. 3.
    [76] In addition, about the structure similar to the gas furnace shown in FIG. 1, the same code | symbol is attached | subjected and the description is abbreviate | omitted.
    [77] In the fourth embodiment, the heat insulation space 12 is formed to be sealed except for the air supply port 45 and the discharge port 46, and is formed to return to the periphery of the bottom surface of the combustion chamber 10.
    [78] Then, the air supply passage 20 (corresponding to the 'first air supply communication tube' of the present invention) is connected to the supply port 45 of the heat insulating space 12, and the mixing pipe 23 (the second air supply of the present invention). Corresponds to the communication pipe ') is connected to the outlet 46 of the heat insulating space (12). Therefore, the air sucked by the air supply / exhaust fan 6 is supplied to the burner 2 through the air supply passage 20, the heat insulation space 12, and the mixing pipe 23.
    [79] In this case, by the air flowing from the supply port 45 to the outlet 46, that is, the air passing through the heat insulating space 12, the heat insulating effect by the heat insulating space 12 can be enhanced, and the heat insulating space 12 The air passing through the heat insulating space 12 may be heated by the heat emitted from the side 11 and the bottom of the bottom 11).
    [80] And since the heated air is supplied to the burner 2 through the mixing pipe 23 as combustion air, the combustion temperature of the burner 2 can be raised similarly to 2nd and 3rd embodiment mentioned above. In addition, the radiation conversion efficiency in the porous body 3 can be improved.
    [81] Subsequently, a fifth embodiment of the present invention will be described with reference to Fig. 4A.
    [82] In addition, about the structure similar to the gas furnace shown in FIG. 1, the same code | symbol is attached | subjected and the description is abbreviate | omitted.
    [83] In the fifth embodiment, the outlet 60 of the heat insulating space 12 is formed so as to communicate with the combustion chamber 10. Therefore, during combustion of the burner 2, the air supplied through the air supply branch pipe 15 flows into the combustion chamber 10 from the discharge port 60 via the heat insulation space 12 in the supply port 13.
    [84] And since the atmospheric temperature in the combustion chamber 10 falls by the air which flowed into the combustion chamber 10 from the discharge port 60, the quantity of heat discharge | released from the side surface 11 of the combustion chamber 10 is reduced, and by this the combustion chamber It is possible to prevent the inside of the gas furnace 1 from becoming an abnormally high temperature state by the heat released from the side surface 11 of the (10). Moreover, since the atmospheric temperature in the combustion chamber 10 falls, it can prevent that the upper surface of the glass upper plate 4 becomes overheated.
    [85] In addition, in this 5th Embodiment, although air was supplied to the combustion chamber 10 through the heat insulation space 12, without providing the heat insulation space 12, it is direct from the air supply branch pipe 15 into the combustion chamber 10. FIG. Also when supplying air, the effect of this invention can be acquired.
    [86] Subsequently, a sixth embodiment of the present invention will be described with reference to Fig. 4B.
    [87] In addition, about the structure similar to the gas furnace shown in FIG. 1, the same code | symbol is attached | subjected and the description is abbreviate | omitted.
    [88] In the sixth embodiment, the outlet 61 of the heat insulating space 12 is connected to the combustion chamber 10 in the same manner as in the fifth embodiment, and the outlet 61 is formed of the glass upper plate 4. It is arranged toward the lower surface.
    [89] Therefore, the heat insulating effect by the heat insulating space 12 is obtained similarly to 1st embodiment mentioned above, and the glass top plate 4 is cooled by the air blown toward the glass top plate 4 in the discharge port 61. As shown in FIG. By enhancing the effect, the atmosphere temperature in the combustion chamber 10 can be reduced in the same manner as in the fifth embodiment.
    [90] In addition, in the above-described fifth and sixth embodiments, the cooling air is supplied into the heat insulating space 12 by the air supply / exhaust fan 6, but by a fan provided separately from the air supply / exhaust fan 6. The cooling air may be supplied into the heat insulating space 12.
    [91] In the first to sixth embodiments described above, the gas furnace 1 in which the porous body 3 is disposed outside the burner 2 is shown. On the contrary, the burner is placed on the outside while the porous body 3 is placed inside. The application of the present invention is also possible when the arrangement is to be arranged.
    [92] As described above, according to the present invention, it is possible to provide a gas furnace which can prevent the internal electronic device parts from becoming overheated by heat dissipation at the side surfaces of the combustion chamber.
