Japanese Patent Laid-Open No. 10-68525 JP 2004-305626 A

  By the way, in the grill apparatus provided with two gas burners on the upper and lower sides, the lower gas burner arranged in the grill cabinet is usually arranged at the lower part of both side surfaces in the grill cabinet, and the side surface in the grill cabinet is grilled with fat. If it is scattered on the bottom surface, the side surface in the grill cabinet has many irregularities due to the structure in which the gas burner is arranged, and it is difficult to clean the inner wall surface of the grill cabinet. Further, since the gas burner is fixed in the grill cabinet and cannot be removed, it is difficult to clean the lower gas burner which is easily contaminated.

  Moreover, in the grill apparatus provided with two electric heaters on the upper and lower sides, the two electric heaters are disposed in the grill box in an exposed state. These electric heaters are composed of linear electric heaters (seeds heaters) bent in a meandering manner. And since the lower linear electric heater is arranged directly below the grill net on which the fish is placed, when the fish is baked and fat is scattered on the side and bottom surfaces in the grill cabinet, the lower linear electric heater It will adhere to the electric heater. Since the lower linear electric heater is fixed in the grill cabinet, it cannot be removed, and it is very difficult to remove the grease adhering to the linear electric heater.

  The present invention has been made in view of the above circumstances, and while the food to be cooked can be satisfactorily boiled, the lower heating portion disposed in the grill cabinet is not easily contaminated with fat, and the inside of the grill cabinet is easily cleaned. An object of the present invention is to provide a grill apparatus that can perform the above-described process.

The present invention is a grill device including an upper heating unit that heats the food to be cooked accommodated in the grill warehouse from above, and a lower heating unit that heats the food to be cooked from below.
The lower heating unit includes a flat radiator having a flat upper surface and a linear electric heater that heats the flat radiator, and the linear electric heater is provided at a position not exposed on the upper surface side of the flat radiator. The radiator is a grill device that is assembled to the bottom surface of the grill cabinet so that the top surface is exposed in the grill cabinet.

  In the grill device, the lower heating unit is not configured to heat the food to be cooked by exposing the gas burner or the linear electric heater in the grill chamber as in the prior art, but the linear electric heater serving as a heating source is in the grill chamber. In addition, a flat radiator that is heated by a linear electric heater is assembled to the bottom surface of the grill cabinet so that the top surface is exposed in the grill cabinet.

  Therefore, according to the grill device, the lower heating unit can dissipate heat almost uniformly from the entire upper surface of the flat radiator when the heat of the linear electric heater is transmitted to the flat radiator. The lower surface side can be heated uniformly, and the temperature distribution on the object to be cooked is uniform compared to the case where the object to be cooked is heated only with a conventional linear electric heater, and the lower surface of the object to be cooked is uniformly baked. be able to. Furthermore, since the flat radiator that heats the object to be cooked has a larger surface area than the linear electric heater, and can store heat, by storing a part of the heat of the upper heating unit in the flat radiator, The amount of heating of the flat radiator by the linear electric heater can be reduced. As a result, it is possible to save energy by reducing the power consumption of the linear electric heater.

  Furthermore, according to the grill device, the lower heating unit is not contaminated with grease because the linear electric heater is not exposed in the grill cabinet, and only the upper surface of the flat radiator exposed in the grill cabinet needs to be cleaned. So cleaning becomes easy. Furthermore, the bottom surface of the grill cabinet can be brought close to a flat state by assembling the flat radiator to the bottom surface portion of the grill cabinet so that the level difference between the bottom portion of the grill cabinet and the flat radiator is as small as possible. The inner surface can be easily cleaned.

  In the grill device, the grill pan on which the food is placed is arranged so that the bottom surface of the grill pan is in contact with the upper surface of the flat radiator, and the temperature of the planar radiator is detected by the planar radiator. The temperature sensor is preferably provided so as not to be exposed on the upper surface of the flat radiator.

According to the above grill device, the food to be cooked is heated on the grill pan, so that the fat of the food to be cooked does not fall on the flat heat radiator, and the flat heat radiator is difficult to get dirty. Since the bottom surface of the grill pan on which the object is placed is in contact, the heat radiated from the flat radiator is efficiently transmitted to the grill pan, and the food to be cooked is heated with the heat of the heated grill pan. Can do. And since the flat radiator and the grill pan are in contact, the temperature of the grill pan can be monitored via the detected temperature of the flat radiator, and the temperature management of the grill pan is facilitated by the temperature detection result, It is possible to prevent the temperature of the grill pan from rising to the ignition temperature of the object to be cooked. Furthermore, since the temperature sensor is disposed so as not to be exposed on the upper surface of the flat radiator, the upper surface of the flat radiator can be a smooth surface having no irregularities. As a result, when cleaning the bottom surface in the grill cabinet, the temperature sensor is not contaminated with grease, and the cleaning can be performed by a simple operation of wiping the bottom surface portion of the grill cabinet and the top surface of the flat radiator. In addition, since the top surface of the flat radiator can be made smooth without any irregularities, the grill pan can be reliably brought into contact with the flat radiator, and the heat from the grill pan can be reliably transferred to the flat radiator. The temperature of the grill pan can be monitored without detecting the temperature of the pan.
Furthermore, since the food to be cooked is heated on the grill pan, there is no need to use a grill having a complicated structure as in the prior art, and troublesome care of the grill is not required.

  In the grill device, the grill pan on which the food is placed is arranged such that the bottom surface of the grill pan is in contact with the top surface of the flat radiator, and the temperature of the grill pan is detected by the flat radiator. It is good also as a structure which provides a temperature sensor so that it may penetrate a planar heat radiator and may contact a grill pan.

  Even with such a configuration, the flat radiator is hard to get dirty, and the heat radiated from the flat radiator can be efficiently transmitted to the grill pan, and the food to be cooked can be cooked with the heat of the heated grill pan. it can. Since the temperature sensor is in contact with the grill pan, it is possible to directly measure the temperature of the grill pan, the temperature detection result facilitates the temperature control of the grill pan, and the temperature of the grill pan ignites the cooking object. It is possible to prevent the temperature from rising.

  By the way, the temperature of a grill pan and the temperature of a plane heat radiator do not necessarily correspond. Therefore, by providing a temperature sensor that directly detects the temperature of the grill pan and a temperature sensor that detects the temperature of the flat radiator, finer and more accurate temperature control is possible.

Furthermore, in the above grill device for arranging the grill pan,
A support frame body that supports the grill plate and is put in and out of the grill cabinet together with the grill plate,
The support frame has a rectangular shape that is larger than the upper surface of the flat radiator, and has a protruding portion that protrudes downward in the width direction outside the width of the flat radiator on the back side with respect to the loading / unloading direction of the grill cabinet. The side end is fixed to the grill door that opens and closes the grill cabinet, and the protruding portion is configured to contact the bottom surface of the grill cabinet,
On the bottom surface of the grill cabinet, a recess is formed in which the protruding portion enters at a position where the support frame is inserted into the storage position in the grill cabinet,
Further, when the protrusion of the support frame is inserted into the recess, the bottom surface of the grill pan supported by the support frame contacts the upper surface of the flat radiator, and the protrusion is detached from the recess. It is preferable that the bottom surface of the grill pan is separated from the upper surface of the flat radiator.

  According to the above grill device, when the grill door is opened and closed and the grill pan with the support frame is put in and out of the grill cabinet, only the protrusion provided on the back side of the support frame on which the grill pan is placed is the bottom portion of the grill cabinet. The grill pan and the support frame can be moved without contacting the surface of the flat radiator with the surface of the flat radiator, thereby preventing the surface of the flat radiator from being damaged by the grill pan. it can. Therefore, even if the temperature sensor for detecting the temperature of the bottom surface of the grill pan is exposed from the top surface of the flat radiator, the temperature sensor can be prevented from being damaged when the grill pan is put in and out.

  Furthermore, in the grill device, it is preferable that the upper heating unit has a gas burner. Since the upper surface of the object to be cooked is heated by the gas having water vapor by the upper heating unit, the outer surface of the object to be cooked is crisp and the finish is improved. Furthermore, since the gas burner can burn smoke and can generate convection in the grill with the combustion gas, it is possible to prevent the smoke from filling the grill with the flow of combustion exhaust.

  As described above, in the grill device of the present invention, the lower heating unit is configured such that the linear electric heater is not exposed in the grill cabinet and the upper surface of the flat radiator is exposed in the grill cabinet. As for the part, the linear electric heater is not soiled with grease, and only the upper surface of the flat radiator that is exposed in the grill cabinet needs to be cleaned. Furthermore, since the bottom surface of the grill cabinet can be brought close to a flat state by assembling the flat radiator to the bottom portion of the grill cabinet so that the level difference between the bottom portion of the grill cabinet and the flat radiator is as small as possible, The inner surface can be easily cleaned.

(Embodiment 1)
Hereinafter, a grill device according to Embodiment 1 of the present invention will be described with reference to FIGS. 1 to 8.
As shown in FIG. 1, the grill device 2 according to the first embodiment is a rear exhaust-type grill device 2 incorporated in a built-in gas stove 1 that is used by being embedded in a countertop C of a system kitchen.

  The gas stove 1 has a goblet 12 that supports cooking utensils such as a pan and a frying pan placed on the top surface of the top plate 11, and a cooker burner that heats the cooking utensil with a gas combustion flame in the center of the 5th virtue 12. 13 is disposed.

  The grill device 2 is provided inside the gas stove 1, and includes a grill cabinet 3 for cooking food to be cooked such as fish, and an upper heating unit 4 assembled to the ceiling portion 31 of the grill cabinet 3. The lower heating part 5 assembled to the bottom face part 32 of the grill cabinet 3 is provided. Further, the front surface of the grill cabinet 3 is opened and closed by an openable / closable grill door 33. A bar 34 is fixed to the front surface of the grill door 33. By gripping the bar 34, the grill door 33 is slid back and forth to open and close the front opening of the grill cabinet 3. Yes. A grill pan 6 is disposed in the grill cabinet 3, and the cooking object placed on the grill pan 6 is heated by the upper heating unit 4 and the lower heating unit 5.

  The grill cabinet 3 is a substantially rectangular parallelepiped shape whose front surface is opened, and is formed of a thin steel plate. It is preferable to apply a fluorine coat or a catalyst coating on the inner wall surface of the grill cabinet 3 so that the burned dirt can be wiped off immediately. Moreover, it is preferable that the inner wall member of the grill cabinet 3 is made of stainless steel having excellent strength.

  The upper heating unit 4 is composed of a surface combustion type gas burner 41 having a ceramic combustion plate in which a large number of flame holes are formed. The upper heating unit 4 is assembled to the ceiling 31 of the grill cabinet 3 with the combustion plate facing downward. Yes. And if the upper heating part 4 is burned, a combustion plate will be red-hot and the to-be-cooked object put on the grill pan 6 will be heated from upper direction with the radiant heat from a combustion plate.

  By configuring the upper heating unit 4 with the gas burner 41, the outer surface of the object to be cooked can be crisply burned by the combustion of the gas containing water vapor, so that the finish of baking is improved. Further, the gas burner 41 can burn smoke, and can also generate convection in the grill 3 by the combustion gas, so that a flow of combustion exhaust is created to fill the grill 3 with smoke. Can be suppressed.

As shown in detail in FIG. 3, the lower heating unit 5 includes a linear electric heater 51 and a flat radiator 52 disposed above the linear electric heater 51.
As the linear electric heater 51, a linear electric heater (seeds heater) bent in a meandering shape or a circular shape is used. In the present embodiment, a sheathed heater bent into a circle (for example, power consumption 700 W with an AC 100 V power supply) is used. The linear electric heater 51 can perform fine temperature control.

  The flat radiator 52 of the lower heating unit 5 is made of a casting because irregularities are formed on the bottom surface. The planar radiator 52 is formed by casting a metal having excellent thermal conductivity such as aluminum, aluminum alloy, copper, or copper alloy. The flat radiator 52 is formed in a disk shape that covers the linear electric heater 51 bent into a circle and covers the opening 35 formed in the bottom surface portion 32 of the grill 3.

  Further, the flat radiator 52 has a flat upper surface, and as shown in detail in FIG. 4, the through-hole 53 through which a first temperature sensor 71 for detecting the temperature of the bottom surface of the grill pan 6 described later passes is formed in the center. 3 and FIG. 4, an annular protrusion that is curved downward and is fixed to the opening 35 of the bottom surface 32 of the grill 3 outside the through-hole 53 on the lower surface. 54 is formed. Further, a recess 55 is inserted between the through hole 53 and the annular protrusion 54 on the lower surface so that a second temperature sensor 72 for detecting the temperature of the planar heat radiator 52 described later is not exposed on the upper surface of the flat heat radiator 52. Is formed.

  As shown in FIGS. 1 and 2, the flat radiator 52 is assembled so as to cover the opening 35 formed in the bottom portion 32 of the grill cabinet 3, so that the bottom radiator 32 and the planar radiator 52 of the grill cabinet 3 are assembled. It is assembled to the bottom surface portion 32 of the grill cabinet 3 so that the step is as small as possible. The linear electric heater 51 is completely covered by the flat radiator 52 and is disposed below the bottom surface portion 32 of the grill 3. The linear electric heater 51 is exposed inside the grill 3. It is supposed not to. That is, in the lower heating unit 5, only the upper surface of the flat radiator 52 is exposed to the inside of the grill cabinet 3.

  Further, the size of the upper surface of the flat radiator 52 is smaller than the size of the bottom surface of the rectangular grill pan 6. By making the upper surface of the flat radiator 52 smaller than the bottom surface of the grill pan 6, the upper surface of the flat radiator 52 is covered with the grill pan 6. The body 52 is difficult to get dirty. Moreover, since the temperature of the outer peripheral portion of the grill pan 6 that does not come into contact with the flat radiator 52 is lower than that of the center portion, it is possible to suppress the temperature rise of the fat that has come out of the cooking object and accumulated around the grill pan 6.

  Further, the first temperature sensor 71 for measuring the temperature of the grill pan 6 is substantially flush with the upper surface of the flat radiator 52 through the through hole 53 so as to directly measure the temperature of the grill pan 6. It is exposed to become. The first temperature sensor 71 is not shown in each figure, and only a contact portion having a circular plane that contacts the bottom surface of the grill pan 6 is described. The first temperature sensor 71 is composed of a thermistor, and by directly measuring the temperature of the grill pan 6 with the first temperature sensor 71, it is possible to prevent the fat of the cooking object from being ignited. The first temperature sensor 71 may be a bimetal switch or a thermocouple.

  The second temperature sensor 72 that detects the temperature of the planar radiator 52 is formed of a thermistor and is flat so as not to be exposed from the upper surface of the planar radiator 52 in order to detect the internal temperature of the planar radiator 52. The heat sink 52 is inserted into the recess 55 from the lower surface side. Since the second temperature sensor 72 does not penetrate the flat radiator 52, it does not directly contact the grill pan 6. However, by detecting the internal temperature of the flat radiator 52 directly by the second temperature sensor 72, the flat radiator is provided. In addition to monitoring the temperature of the 52 itself, the temperature of the grill pan 6 can also be monitored via the detected temperature of the flat radiator 52.

In the first embodiment, the temperature of the grill pan 6 and the temperature of the flat radiator 52 do not necessarily match. Therefore, the first temperature sensor 71 that directly detects the temperature of the grill pan 6 and the temperature of the flat radiator 52 are detected. Two temperature sensors 72 are provided. Thus, by providing two temperature sensors, finer temperature control becomes possible.
In the first embodiment, although not shown, a temperature sensor for measuring the internal temperature of the grill cabinet 3 is also provided in the grill cabinet 3 separately.

  The grill device 2 is heated with the upper heating unit 4 and the lower heating unit in order to discharge oil smoke generated from an object to be cooked in the grill cabinet 3 and combustion gas generated in the upper heating unit 4 to the outside of the grill cabinet 3. An exhaust passage 8 communicating from the inside of the grill 3 to an exhaust port formed on the rear upper surface of the top plate 11 of the gas stove 1 is also formed behind the portion 5.

  Further, as shown in FIG. 2, a partition plate 81 having a perforation is provided between the grill 3 and the exhaust passage 8, and in the lower portion of the exhaust passage 8 near the partition plate 81, An afterburner 82 is arranged. The after burner 82 is installed in a posture with the combustion surface facing upward. The afterburner 82 is composed of a surface combustion type gas burner similar to the upper heating unit 4 and burns off oil smoke generated from the food to be smokeless and bromide-free. Note that the afterburner 82 may be a Bunsen burner.

  According to the grill device 2 of the first embodiment, when the cooking object in the grill warehouse 3 is heated by the upper heating unit 4 and the lower heating unit 5, oil smoke and combustion gas generated from the cooking object are exhausted from the exhaust passage 8. Is flowed into. At this time, by burning the afterburner 82, the oily smoke can be burned out and smokeless and non-brominated.

  In the grill device 2 of the first embodiment, since the partition plate 81 that partitions the grill store 3 and the exhaust passage 8 is provided, the cleaning range of the grill device 2 is more than the partition plate 81 in the grill store 3. It can be in the front range, the cleaning range can be narrowed, and the inside of the exhaust passage 8 in which the after burner 82 is disposed is hardly contaminated.

  The grill pan 6 disposed in the grill cabinet 3 is made of an aluminum casting and is formed into a shallow rectangular pan as a whole. The grill pan 6 has a thickness of 5 mm in contact with the flat radiator 52 and a thickness of 2 mm in other portions, so that the heat of the lower heating unit 5 can be transmitted uniformly. As shown in FIG. 6, the portion of the bottom surface of the grill pan 6 that is in contact with the flat radiator 52 is formed thick so that it rises in a circular shape slightly larger than the diameter of the flat radiator 52. The portion of the bottom surface of the grill pan 6 that contacts the flat radiator 52 improves the thermal conductivity from the flat radiator 52 to the grill pan 6, so that the bottom surface of the grill pan 6 contacts the entire top surface of the flat radiator 52. It is formed on a flat surface. Further, on the bottom surface of the grill pan 6, a long engagement protrusion 61 to be engaged with a support frame body 9 described later is formed near the edge of the long bottom surface portion, and both short surfaces of the bottom surface are formed. A concave portion 62 in which the bent portion 91 of the support frame 9 is fitted is formed at the edge of the center of the side portion.

  Furthermore, as shown in FIGS. 1, 2 and 5, a large number of ridges 63 are formed on the upper surface side of the grill pan 6 so as to project linearly at equal intervals. In order to make the contact area to 6 as small as possible, the food to be cooked is brought into line contact with the ridges 63 so that the food to be cooked hardly reaches the bottom surface of the grill pan 6. Furthermore, as shown in the cross-sectional view of the grill pan 6 in FIG. 7, the surface of the root portion of the ridge 63, which is the upper surface of the grill pan 6, is formed so as to be raised so that the central portion rises and comes out of the object to be cooked. Fat is allowed to flow around the grill pan 6 and collected.

  As shown in FIG. 1, the grill door 33 that opens and closes the front opening of the grill cabinet 3 is slidably supported by a member constituting the grill cabinet 3 via a guide rail 37. Further, a support frame body 9 that supports the grill pan 6 is integrally fixed to the grill door 33, and the support frame body 9 is placed in a state where the grill pan 6 is placed as the grill door 33 slides back and forth. Also comes to move back and forth. Therefore, when the grill door 33 is closed, the support frame 9 on which the grill pan 6 is disposed is accommodated in the grill cabinet 3, and when the grill door 33 is pulled out and opened, the support frame 9 is also removed. To be drawn. Then, the grill pan 6 supported by the support frame 9 is put into and out of the grill cabinet 3 by opening and closing the grill door 33.

  The support frame 9 that supports the grill pan 6 is formed by bending a metal wire such as stainless steel, and is formed in a rectangular shape larger than the circular surface of the flat radiator 52 as shown in FIG. ing. As shown in FIG. 6, a bent portion 91 that is bent in the horizontal direction toward the inner side fitted in the recess 62 formed on the bottom surface of the grill pan 6 is formed on the short side portion on the back side of the support frame 9. The short side portion formed on the front side is bent downward and is fixed to the grill door 33. And the long side part of the support frame 9 is engaged with the inner surface side of the engaging projection part 61 formed in the bottom face of the grill pan 6. As shown in FIG. As described above, the support frame 9 supports the grill pan 6 at a predetermined height by the pair of long sides and the short side on the back side.

  Further, as shown in detail in FIG. 8, the support frame 9 is formed with a protruding portion 92 that protrudes downward and curves at the distal end portion of the long side portion. As shown in FIGS. 5 and 8, the protruding portion 92 is covered with a cap 93 that follows the curved shape of the protruding portion 92, and the protruding portion 92 and the cap 93 are integrated. Therefore, the middle portion in the longitudinal direction of the bottom of the cap 93 projects downward in the same manner as the projecting portion 92. The cap 93 is made of a material having heat resistance such as a fluororesin and capable of reducing the frictional resistance with the bottom surface of the grill cabinet 3 as much as possible.

  The support frame 9 is fixed to the grill door 33 that opens and closes the grill cabinet 3 with the short side portion on the near side fixed to the bottom surface portion 32 of the grill cabinet 3 through the projecting portion of the cap 93. It is comprised so that it may contact.

  Further, as shown in FIG. 8, a protruding portion 92 protrudes from the cap 93 at the back end portion of the bottom surface portion 32 of the grill cabinet 3 in a state where the support frame 9 is arranged at the baking position in the grill cabinet 3. A recess 36 is formed through the portion.

  The support frame body 9 is formed in such a shape, and the recess 36 is formed in the bottom surface portion 32 of the grill cabinet 3, so that the protrusion 92 of the support frame body 9 is formed as shown by the solid line in FIG. When the protruding portion of the attached cap 93 enters the recess 36 of the grill cabinet 3, the grill cabinet 3 with the bottom surface of the grill pan 6 supported by the support frame 9 in contact with the top surface of the flat radiator 52. A grill pan 6 is disposed inside the. At this time, the support frame body 9 is arranged so as to be hidden behind the grill pan 6, so that it is difficult to get dirty, and since it is composed of only the wire, it is easy to clean.

  As shown by a two-dot broken line (virtual line) in FIG. 8, the protruding portion of the cap 93 is removed from the recessed portion 36 together with the protruding portion 92, and the protruding portion of the cap 93 is in contact with the bottom surface portion 32 of the grill cabinet 3. In some cases, the bottom surface of the grill pan 6 is separated from the top surface of the flat radiator 52 by a distance h.

  Thus, when the support frame 9 supports the grill pan 6 and the grill pan 6 and the support frame 9 are accommodated in a predetermined position in the grill cabinet 3, the bottom surface of the grill pan 6 is the lower heating unit. 5 is in contact with the upper surface of the flat radiator 52. When the grill door 33 is opened and the grill pan 6 together with the support frame 9 is taken in and out of the grill cabinet 3, only the cap 93 covering the protruding portion 92 of the support frame 9 contacts the bottom surface portion 32 of the grill cabinet 3. Since the grill pan 6 and the support frame 9 are moved while the grill pan 6 is moving, the grill pan 6 can be prevented from contacting the surface of the flat radiator 52 and the first temperature sensor 71 during the movement of the grill pan 6. As a result, it is possible to prevent the grill pan 6 from damaging the upper surface of the flat radiator 52 and the first temperature sensor 71 when the grill pan 6 is put in and out.

  In the first embodiment, the support frame 9 is fixed to the grill door 33 of the grill warehouse 3, but the front side short side portion and the protrusion 92 of the support frame 9 are covered without being fixed to the grill door 33. The cap 93 can be brought into contact with the bottom surface portion 32 of the grill cabinet 3 to support the grill pan 6 in the grill cabinet 3. In this case, after the grill door 33 is opened, the grill pan 6 is pulled out from the grill cabinet 3 by pulling the support frame 9 forward.

  Next, the operation | movement at the time of cooking of the grill apparatus 2 in this Embodiment 1 is demonstrated. When cooking the food to be cooked, the grill door 33 is opened, the grill pan 6 is pulled out, the food to be cooked is placed on the grill pan 6, the grill pan 6 is returned into the grill cabinet 3, and the grill door 33 is opened. Close. When the grill pan 6 is being moved, the grill pan 6 is moved away from the upper surface of the flat radiator 52 by the support frame 9, so that the grill pan 6 includes the flat radiator 52 and the first temperature sensor. 71 does not touch.

  In the state where the grill pan 6 is disposed in the grill cabinet 3, for example, the upper heating unit 4 and the afterburner 82 are ignited, and the linear electric heater 51 of the lower heating unit 5 is energized to supply the flat radiator 52. Start cooking by heating. At this time, the grill pan 6 comes into contact with the upper surface of the flat radiator 52 while being supported by the support frame 9 while being kept horizontal in the grill cabinet 3.

  According to the grill device 2 of the first embodiment, when the cooker is heated from above by the upper heating unit 4, the linear electric heater 51 of the lower heating unit 5 is energized to heat the flat radiator 52. The grill pan 6 placed in contact with the upper surface of the flat radiator 52 is heated, and the lower surface side of the object to be cooked placed on the grill pan 6 is heated. In addition, since the lower heating part 5 heats the planar radiator 52 by the linear electric heater 51 and heats the food to be cooked via the grill pan 6, when a gas burner is used as the lower heating part as in the prior art, In comparison, the lower surface side of the object to be cooked is less likely to burn.

  In the lower heating unit 5, the heat of the linear electric heater 51 is transmitted to the entire flat radiator 52 and can be dissipated almost uniformly from the entire upper surface of the flat radiator 52. The whole grill pan 6 except the periphery of the grill pan 6 can be heated uniformly, and the lower surface side of the object to be cooked can be heated uniformly. That is, compared with the case where the cooking object is heated only by the linear electric heater 51, the temperature distribution with respect to the cooking object can be made uniform, and the cooking object can be baked uniformly.

  When the heat from the upper heating unit 4 passes through the side of the food to reach the grill pan 6, the heat from the upper heating unit 4 is also stored in the grill pan 6 and passes through the grill pan 6. Since the heat is also stored in the flat radiator 52, the heating amount of the flat radiator 52 by the linear electric heater 51 can be reduced. That is, since the flat radiator 52 is also heated by a part of the heat from the upper heating unit 4, the power consumption of the linear electric heater 51 can be reduced and energy saving can be achieved. In particular, when the grill pan 6 and the flat radiator 52 are made of aluminum, since aluminum has a large heat storage capacity, the power consumption of the linear electric heater 51 can be reduced as much as possible. In the first embodiment, the first temperature sensor 71 that directly detects the temperature of the bottom surface of the grill pan 6 and the second temperature sensor 72 that detects the temperature of the flat radiator 52 are provided. The temperature of the flat radiator 52 can be adjusted according to the detected temperature of the grill pan 6 heated by heat.

  Furthermore, in the grill device 2 according to the first embodiment, the planar electric heater 51 is not exposed in the grill cabinet 3 and only the upper surface of the planar radiator 52 is exposed in the grill cabinet 3. Is assembled to the bottom surface portion 32 of the grill cabinet 3. Therefore, the bottom surface portion 32 of the grill cabinet 3 and the flat radiator 52 are integrated so that the level difference of the bottom surface of the grill cabinet 3 can be made as small as possible. Therefore, as in the conventional case, a gas burner or a sheathed heater is provided in the grill cabinet 3. Is not exposed, and when cleaning the inner surface of the grill cabinet 3, it is possible to perform maintenance with a simple operation of simply wiping the upper surface of the flat radiator 52 and the wall surface of the grill cabinet 3, thereby facilitating cleaning. .

  Furthermore, according to the grill device 2 according to the first embodiment, the bottom surface of the grill pan 6 is brought into contact with the top surface of the flat radiator 52, the grill pan 6 is heated by the flat radiator 52, and the heat of the grill pan 6 is Since the food to be cooked is cooked by heating, the heat efficiency is good and the temperature difference between the flat radiator 52 and the grill pan 6 is small, so that the temperature control of the grill pan 6 is easy, and the temperature of the grill pan 6 is Can be prevented from rising to the ignition temperature. Note that when the abnormal temperature is detected by the first temperature sensor 71 and / or the second temperature sensor 72, the heating of the linear electric heater 51 may be stopped. Further, since the food to be cooked is heated on the grill pan 6, it is not necessary to use a grill having a complicated structure as in the prior art, and only the grill pan 6 is cleaned, so that the troublesome maintenance of the grill is not required. .

  In addition, in this embodiment, when heating a to-be-cooked object, the 1st mode which uses the upper heating part 4, the afterburner 82, and the lower heating part 5, the upper heating part 4 and the lower heating without using the afterburner 82 The second mode using the part 5, the third mode using only the lower heating part 5, and the fourth mode using the upper heating part 4 and the afterburner 82 without using the lower heating part 5 are switched for heating. be able to. Further, the upper heating unit 4 controls the heating power with strength, and the lower heating unit 5 can perform ON / OFF control in three stages. Thus, fine temperature control becomes possible by controlling each mode and heating power and power adjustment.

Is provided so as not to penetrate the flat radiator 52. In the second embodiment, as shown in FIGS. 9 and 10, the flat radiator 52 is not provided with the first temperature sensor 71 that directly contacts the grill pan 6 and measures the temperature of the grill pan 6. Only the second temperature sensor 72 which is not exposed on the upper surface of 52 is provided.

  In the second embodiment, as shown in FIGS. 9 and 10, the second temperature sensor 72 is arranged at the center of the flat radiator 52 that is not easily affected by heating directly from the linear electric heater 51. A recess 56 into which the second temperature sensor 72 for detecting the temperature of the planar heat dissipating body 52 is inserted is formed on the lower surface of the central portion of the body 52 so as not to penetrate. The second temperature sensor 72 is inserted into the concave portion 56 from the lower surface side of the flat radiator 52 so as not to be exposed from the upper surface of the flat radiator 52. In the second embodiment, except that the first temperature sensor 71 is not provided, the through-hole is not formed in the planar radiator 52, and the position where the second temperature sensor 72 is disposed is different. Since it is the same structure as Embodiment 1, description is abbreviate | omitted.

  In the first embodiment, since the first temperature sensor 71 is exposed on the upper surface of the planar radiator 52, the durability of the first temperature sensor 71 is reduced, and the first temperature sensor 71 and the through hole between the planar radiator 52 are used. There is a possibility that the slight gap between the grill pan 6 and the first temperature sensor 71 may not be sufficiently cleaned.

  In the second embodiment, the second temperature sensor 72 is arranged on the lower surface side of the flat radiator 52 so as not to be exposed on the upper surface of the flat radiator 52, so that the upper surface of the flat radiator 52 is a smooth surface without unevenness. In addition, the entire bottom surface of the grill pan 6 can be reliably brought into contact with the flat radiator 52. As a result, when the bottom surface in the grill cabinet 3 is cleaned, the second temperature sensor 72 is not contaminated with grease, and the simple operation of wiping off the bottom portion of the grill cabinet 3 and the top surface of the flat radiator 52 is performed. Can be cleaned. Further, since the upper surface of the flat radiator 52 can be a smooth surface without unevenness, the grill pan 6 can be reliably brought into contact with the flat radiator 52 and the heat of the grill pan 6 can be reliably transferred to the flat radiator 52. Therefore, unlike the first embodiment, the first temperature sensor 71 does not directly detect the temperature of the grill pan 6, but detects the internal temperature of the flat radiator 52 through the detected temperature of the flat radiator 52. The temperature of the pan 6 can be monitored.

  When the temperature of the grill pan 6 is managed by the second temperature sensor 72, the temperature of the upper surface of the grill pan 6 and the temperature of the upper surface of the flat radiator 52 are adjusted by bringing the entire bottom surface of the grill pan 6 into contact with the flat radiator 52. The temperature difference can be reduced to, for example, about 20 degrees. Thus, even with only the second temperature sensor 72 that does not directly contact the grill pan 6, it becomes easy to manage the temperature of the grill pan 6 based on the temperature detection result, and the temperature of the grill pan is prevented from rising to the ignition temperature of the cooking object. can do. In this case, for example, the detected temperature of the second temperature sensor 72 can be set in the range of 250 ° C. to 260 ° C. as an abnormal temperature for preventing the cooking object from igniting. In addition, the 2nd temperature sensor 72 may be provided in positions other than the center part of the planar heat radiator 52, and may be provided with two or more in an appropriate position. In the second embodiment, the second temperature sensor 72 is a thermistor, but may be a bimetal switch or a thermocouple. In the case where a plurality of thermistors are provided, a combination of a thermistor, a bimetal switch, and a thermocouple may be used.
