A pair of side plates (hereinafter, referred to as “cover side plates”) 275, and an upper wall (hereinafter, referred to as a “heater upper wall”) 201 and a side wall (hereinafter, referred to as a “heater side wall”) 205 inside the heating chamber 20. It is provided from above the grill plate 26 to the side, and extends in the front-rear direction of the heating cabinet 20 so as to cover the grill plate 26.

  As shown in FIG. 3, the upper cover plate 271 faces the lower side of the upper wall 201 of the heating chamber with a predetermined gap 20C. On the other hand, the cover side plate 275 faces substantially parallel to the inside of the heating chamber side wall 205 with a predetermined gap 20D. That is, the constituent walls above and on the side of the grill plate 26 in the heating cabinet 20 have a multilayer structure having an air layer (gap 20C, 20D).

  At the center in the left-right direction of the cover upper plate 271, a protruding portion 51 having a downwardly convex substantially V-shaped vertical cross section in front view is formed. Further, at the left and right positions of the projecting portion 51 on the cover upper plate 271, there are formed inclined portions 52 which are inclined upward from near the left and right side edges of the cover upper plate 271 toward the side edges of the projecting portion 51.

  Both the protruding portion 51 and the inclined portion 52 are formed from the front end to the rear end of the cover upper plate 271. Therefore, after being discharged from the grill burner 21, the combustion gas guided to the upper side along the cover side plate 275 along the side of the grill plate 26 after being discharged from the grill burner 21 is guided to the periphery of the protruding portion 51 along the lower surface of the inclined portion 52. , And further guided along the lower surface of the protruding portion 51, that is, to the center of the upper surface of the grill plate 26.

  As shown in FIG. 2, a gap (hereinafter, referred to as “exhaust”) between the cover upper plate 271 and the heating chamber upper wall 201 is located at a position closer to the front than the center of the protrusion 51 in the front-rear direction and at a position closer to the rear. As an exhaust outlet connecting to the passage 20C), an exhaust outlet 53 having a horizontally-long rectangular shape as viewed from above is opened, and a space (hereinafter, referred to as “passage”) between the upper cover plate 271 and the grill plate 26 in the heating chamber 20 is provided. The space 20 </ b> E above the plate) is connected to the internal space 24 </ b> E of the exhaust pipe 24 from the exhaust outlet 53 through the exhaust passage 20 </ b> C.

  The cover rear plate 274 abuts on the front surface of the rear wall 204 of the heating chamber and along the lower edge of the exhaust pipe inlet 240 when the heat collecting cover 27 is accommodated to the rearmost portion in the heating chamber 20, and a space above the plate. The partition walls 20E and the internal space 24E of the exhaust pipe 24 are separated. Therefore, the combustion gas guided to the center of the upper surface of the grill plate 26 and the oil smoke and odor components generated from the food on the grill plate 26 are not directly led out from the rear part of the heating chamber 20 into the exhaust pipe 24, The exhaust gas is led out to the exhaust passage 20C through the exhaust outlet hole 53, is further guided through the exhaust passage 20C from the exhaust tube inlet 240 of the rear wall 204 of the heating chamber into the exhaust tube 24, and is discharged to the outside of the stove body 1 through the exhaust port 14. You.

  As shown in FIGS. 3 and 4, a flange 54 projecting substantially horizontally outward is formed at the lower end of the cover side plate 275. On the other hand, a support rail 55 extending in the front-rear direction and projecting inward of the heating chamber 20 is formed on the inner side surface of the heating chamber side wall 205, and the flange 54 abuts against and is supported by the supporting rail 55 from above. You. Therefore, the heat collecting cover 27 is supported from below in a state in which it can slide back and forth along the support rail 55. If the heat collecting cover 27 is slid forward of the opening 200 with the grill door 22 open, the heating chamber 20 Can be removed from inside.

  The support rails 55 are provided in a plurality of rows (here, two rows) in the vertical direction. If the support position of the flange 54 is changed, the mounting height of the heat collecting cover 27 in the heating chamber 20, that is, on the cover The distance between the plate 271 and the grill plate 26 can be adjusted.

  As shown in FIG. 3, the cover side plate 275 extends substantially vertically downward from the side edge of the cover upper plate 271 toward the outside of the juice receiving portion outer plate 33. On the other hand, among the support rails 55, the uppermost (here, upper) support rail 55 is provided at substantially the same height as the upper surface of the plate support portion 251. That is, when the heat collecting cover 27 is supported by the uppermost support rail 55, the lower end of the cover side plate 275 is located outside the juice receiving portion outer plate 33 and below the height of the side edge 261 of the grill plate 26. It is configured to be located. When the heat collecting cover 27 is supported on the support rail 55 below (in this case, below) the uppermost step, the lower end of the cover side plate 275 is outside the juice receiving portion outer plate 33 and the flame of the grill burner 21. It is located below the height of the hole 210. Therefore, the combustion gas guided from the grill burner 21 to the space inside the juice receiving portion 252 through the gas outlet 310 passes through the side of the grill plate 26 without contacting the heating chamber side wall 205, and is formed inside the cover side plate 275. It is guided along the side surface to the space 20E above the plate.

  As described above, according to the grill 2, the combustion gas discharged from the grill burner 21 in the burner storage portion 20 </ b> A below the grill plate 26 is supplied from the side of the grill plate 26 along the inner side surface of the cover side plate 275. It is smoothly guided to the upper space 20E to heat the grill plate 26 and the heat collecting cover 27. As a result, the food on the grill plate 26 is heated from below by the conductive heat and the radiant heat from the grill plate 26, and the radiant heat from the heat collecting cover 27 and the combustion gas that has flowed to the upper surface 26A side of the grill plate 26. It is heated from above and from the sides by convective heat. That is, the food material on the grill plate 26 is appropriately heated from both the upper and lower surfaces by the combustion gas guided upward from below the grill plate 26 through the sides. Therefore, uneven baking of the food is unlikely to occur, and stable heating performance can be exhibited.

  Moreover, in this embodiment, the food can be appropriately heated from both the upper and lower surfaces only by the grill burner 21 provided below the grill plate 26, so that the gas consumption can be reduced accordingly. Therefore, energy saving is improved. Further, it is not necessary to separately provide a burner for heating the food material from above in the upper part of the heating chamber 20, so that the number of parts and the number of assembling steps of the entire grill 2 can be reduced. Therefore, the manufacturing cost can be reduced.

  Further, in the grill 2, the combustion gas guided to the space 20E above the plate along the cover side plate 275 is led to the exhaust passage 20C from the exhaust outlet hole 53 provided at a position near the front edge of the cover upper plate 271. The exhaust gas is further guided through the exhaust passage 20C to the internal space 24E of the exhaust pipe 24 provided at the rear thereof, and is discharged to the outside of the heating chamber 20, so that the contact time of the combustion gas with the heat collecting cover 27 is long, The heat in the combustion gas can be efficiently recovered by the heat collecting cover 27. Thereby, the gas consumption can be further reduced, and the energy saving performance is further improved.

  Further, the combustion gas guided to the space 20E above the plate is guided toward the center of the upper surface 26A of the grill plate 26 along the protrusion 51 formed at the center in the left-right direction of the cover upper plate 271. It is possible to appropriately heat the central part of the foodstuff, which is relatively difficult to pass heat. Therefore, uneven baking is less likely to occur in the food material, and more stable cooking performance can be exhibited.

  Further, in the grill 2 described above, since the exhaust outlet hole 53 is provided at a position near the front edge and a position near the rear edge of the cover upper plate 271, a relatively wide non-opening surface is provided at the center of the cover upper plate 271 in the front-rear direction. Is secured, the combustion gas guided to the space 20E above the plate can be reliably guided to the center of the upper surface 26A of the grill plate 26 along the protrusion 51 of the cover upper plate 271. Thereby, the center of the food material can be more appropriately heated. Therefore, uneven baking is less likely to occur in the food material, and more stable cooking performance can be exhibited.

  Further, in the grill 2, the combustion gas discharged from the grill burner 21 is transferred to the space 20 </ b> B on the side of the lower surface 26 </ b> B of the grill plate 26 by the raised portion 264 formed near the side edge 261 of the lower surface 26 </ b> B of the grill plate 26. Since direct inflow can be suppressed, the central portion of the grill plate 26 is unlikely to be overheated. Therefore, uneven baking is less likely to occur in the food material, and more stable cooking performance can be exhibited.

  Further, since the grill plate 26 and the heat collecting cover 27 are formed of a material having high thermal conductivity, the temperature of the inside of the heating chamber 20 and the temperature of the grill plate 26 during the heating and cooking of frozen foods, during the cold season, and at the beginning of use, for example. Even under low conditions, the heat in the combustion gas is quickly transmitted to the food through the grill plate 26 and the heat collecting cover 27, so that the food can be more appropriately heated and the gas consumption can be reduced. It is also possible to reduce it. Therefore, energy-saving performance is further improved while exhibiting more stable heating and cooking performance.

  Further, in the grill 2 described above, the height of the heat collecting cover 27 is changed according to the thickness of the food material, and the separation distance between the cover upper plate 271 and the grill plate 26 is adjusted. Since the amount of heat transferred can be adjusted, it is possible to reduce the gas consumption. Therefore, energy saving is further improved. In addition, even if the thickness of the food material is different, heating can be performed appropriately, so that more stable heating and cooking performance can be exhibited.

  Further, since the cover side plate 275 extends from the side edge of the cover upper plate 271 to the height near the side edge 261 of the grill plate 26, the combustion gas guided to the side of the grill plate 26 can be reliably covered. Since it comes into contact with the side plate 275 and is led to the space 20E above the plate, the heat in the combustion gas can be more efficiently recovered by the heat collecting cover 27. Thereby, the gas consumption can be further reduced, and the energy saving performance is further improved.

  Further, since the juice receiving portion outer plate 33 extends inside the cover side plate 275 and above the upper surface height of the plate supporting portion 251, that is, above the lower end of the cover side plate 275, the grill plate 26 is extended. Is smoothly guided to the inside of the cover side plate 275 along the inner surface of the juice receiving portion outer plate 33, so that the heat in the combustion gas is more efficiently collected by the heat collecting cover 27. can do. Thereby, the gas consumption can be further reduced, and the energy saving performance is further improved.

  In addition, since the heat collecting cover 27 is provided from the upper side of the grill plate 26 to the side inside the heating chamber 20, oil and broth scattered from the food are mainly deposited on the inner surface of the heat collecting cover 27. Since it adheres, the heating chamber upper wall 201 and the heating chamber side wall 205 are hardly stained. In addition, since the heat collecting cover 27 can be removed from the inside of the heating chamber 20 and cleaned, the maintainability is high.

  Further, in the grill 2 described above, since the constituent walls above and on the side of the grill plate 26 in the heating chamber 20 have a multi-layered structure having an air layer (gap 20C, 20D), the heat inside the heating chamber 20 is reduced. Is hardly transmitted to the outside, and the thermal load on other components such as the valve unit and the control circuit inside the stove body 10 can be reduced. As a result, it is possible to prevent malfunctions, malfunctions, deformations, and the like of the equipment caused by the thermal load.

  As shown in FIG. 5, the heat collecting cover 27 may be configured such that a corner 277 between the side edge of the cover upper plate 271 and the upper edge of the cover side plate 275 is formed in an arcuate curved shape. In this case, the combustion gas guided upward along the cover side plate 275 from the side of the grill plate 26 flows along the curved surface inside the corner portion 277, and smoothly moves toward the inside center of the heat collection cover 27. The food on the grill plate 26 can be more appropriately heated. Thereby, more stable heating and cooking performance can be exhibited.

  In the above embodiment, the exhaust outlet connecting the space 20E above the plate and the exhaust passage 20C is located at a position closer to the front and a position closer to the rear than the center of the cover upper plate 271 in the front-rear direction. Although the configuration in which the exhaust outlet hole 53 having the shape is provided has been described, the central portion of the food can be appropriately heated by the radiant heat from the heat collecting cover 27, and the combustion gas introduced into the space above the grill plate 26 and As long as oil smoke and the like generated from foods can be smoothly led out to the exhaust passage 20C, even if the exhaust outlet holes 53 are provided at positions near the left and right corners 277 of the cover upper plate 271 respectively. Alternatively, a notch having a predetermined width may be provided at the front edge of the cover upper plate 271.
