TECHNICAL FIELD OF THE INVENTION
The present invention relates to a heating cooker provided with a roaster function for baking meat, fish and the like in a heating range using IH used in a kitchen such as a general household.
[0002]
[Prior art]
Conventionally, the roaster section of this type of heating cooker has the configuration shown in FIG. In the drawing, 31 is a conventional heating cooker main body, and 32 is a heating plate on which a cooker 34 for induction heating by a heating coil 33 is placed. The heating coil 32 has a space 35 for cooling, and a roaster section 36 is arranged below the space 35. Upper and lower heating means 38 and 39 composed of a sheathed heater and a miraclon heater are provided vertically in a cooking chamber 37 of the roaster section 36, and a grill 41 on which the food 40 is placed is connected to the upper and lower heating means 38 and 39. Located between. Below the grill 41, a saucer 42 for receiving the oil falling from the food 40 is provided.
[0003]
In such a configuration, the cooking device 34 is placed on the heating plate 32 of the heating cooking device main body 31, a current flows through the heating coil 32, and the cooking device 34 is heated by induction heating. Is placed on a grill 41, and both sides of the food 40 can be simultaneously baked by the upper and lower heating means 38 and 39, so that the cooking can be automatically terminated. ing.
[0004]
Further, in order to prevent the inside of the refrigerator from being stained by oil or the like that falls from the food 40, a receiving tray 42 is provided detachably. In addition, the tray 42 is ignited when oil falls into the lower heating means 39, and is further filled with water in order to prevent the oil from falling into the tray 42 and continuing the ignition, and to prevent the generation of oil smoke. That is common. Further, a sheathed heater or a Milacron heater is used for the upper and lower heating means 38 and 39, and the surface of the heater is extremely high. Therefore, the roaster part 36 incorporated in such a heating cooker main body 31 requires a large height.
[0005]
[Problems to be solved by the invention]
The heating cooker 31 of the conventional configuration has a function equivalent to a gas range, an electric range, or the like as a heating cooker to be installed around the kitchen, and is a built-in type that is incorporated into a system kitchen, and a range stand next to the kitchen. There are two types of stationary type that can be used by mounting. In the case of the built-in type heating cooker, since it is integrated with the system kitchen, there is a margin in the height direction, and the roaster unit 36 having the conventional configuration can be incorporated to perform double-sided heating. .
[0006]
However, in the stationary type, the height of the range stand is also determined (generally 18 cm) in accordance with the height of a conventional gas range, etc., so that the height of the kitchen counter should be the same as the height and width of the counter. Since the heating coil 32 and the like are required, the height dimension of the roaster section 36 is limited to a relatively small size, and the roaster section 36 cannot be formed by the conventional double-sided heating, and only one side (the upper heating means 38) is provided. In the above configuration, only the height was reduced. For this reason, the cooking thing 40 was taken out halfway, turned over, and it was only possible to cook again by a complicated method of heating again.
[0007]
SUMMARY OF THE INVENTION The present invention solves the above-mentioned conventional problems, and even when the height direction of the roaster part of the heating cooker is limited, a heating cooker that can realize a space-saving double-sided baking heating configuration that can automatically bake both sides. The purpose is to provide.
[0008]

It was done.
[0009]
As a result, the placement container for the food placed on the heating source is directly heated by the heating source, and the heat is efficiently transmitted. For this reason, since the entire mounting container has a uniform and relatively low-temperature heating surface, even if the food is placed in close proximity, uneven grilling is not performed and uniform grilling is possible. For this reason, the dimension between the lower heating means and the food can be greatly reduced, and the uniform heating can be performed, so that the baking performance can be improved.
[0010]
Further, since the food is close to the heating surface, cooking can be performed even if the surface temperature of the lower heating means is significantly reduced. For this reason, even if oil falls on the lower heating means, there is no risk of ignition and there is little generation of oil fumes, so there is no need to pour water, no extra heating energy is used, and less energy is used for cooking. Energy savings. As a result, even in a cooking device having a limited height, such as a stationary type, the food can be heated simultaneously from both sides, and the cooking can be automated, and the usability is greatly improved.
[0011]
BEST MODE FOR CARRYING OUT THE INVENTION
The invention according to claim 1 is a heating coil, a roaster unit provided with a space for ventilation in the heating coil, a housing for accommodating the roaster unit, and a lower part for heating food from below in the roaster unit. Heating means, comprising a mounting container constituting the lower heating means and mounting the food, and a main heating source mounting the mounting container and forming the lower heating means, heating the food is performed. By adopting a configuration in which heating is mainly performed from the placing container, the placing container is directly heated by the heating source, and the heat is efficiently transmitted to the food. Since the entire heating surface of the mounting container has a uniform temperature, even if the food is placed in close proximity, uneven grilling is not possible, uniform grilling is possible, and the size of the roaster in the height direction is small. can do. For this reason, even if only a small space is required, heating means can be provided on the upper and lower sides for baking, and a roaster unit that can automatically bake on both sides can be configured even in a small space.
[0012]
According to the second aspect of the present invention, the placing container is made of a high thermal conductivity material such as aluminum, and the heating cooker according to the first aspect improves heat transfer characteristics in a surface direction on the placing container. A uniform heating temperature can be maintained irrespective of the distribution and location of the food, so that even if the food is placed close to the mounting container heating surface, it can be evenly and evenly grilled. Therefore, the size of the roaster in the height direction can be reduced, and a more space-saving double-sided roaster can be realized.
[0013]
According to a third aspect of the present invention, the main heating source according to the first and second aspects is constituted by a planar heating element such as a mica heater or a print heater. Since the temperature distribution on the storage container heating surface is uniform, the manner of burning the cooked food can be uniform. Further, since the main heating source itself can be configured to be thin, the lower heating means can be configured to be thinner, thereby enabling space-saving double-sided heating.
[0014]
The invention according to claim 4 is characterized in that the main heating source is constituted by a sheathed heater, so that even when the heating element serving as the main heating source is disposed inside the roaster unit, electricity is not supplied to the water or oil from the cooked food during heating. Insulation can be maintained, and further, the main heating source can be brought into direct contact with the mounting container for heating. As a result, there is no need to worry about insulation, etc., and since the thermal efficiency can be increased, heat can be supplied from the main heating source without being affected by the distribution and location of the cooked food, and a more secure thin roaster unit is configured. can do.
[0015]
According to a fifth aspect of the present invention, the lower heating means and the upper heating means are provided, and the upper heating means is constituted by a sheathed heater, so that the surface temperature of the upper heating means can be increased. For this reason, even if the food is provided close to the lower heating means and the distance from the upper heating means is increased, the food can be sufficiently baked with radiant heat. In addition, a sufficient distance between the upper heating means and the food can be ensured, a configuration in which the food can be easily taken in and out of the cooking chamber can be achieved, and even a larger food can be baked, thereby improving usability.
[0016]
The invention according to claim 6 can prevent the food from sticking to the surface of the mounting container by configuring the surface of the mounting container with a non-adhesive material such as Teflon, so that the surface of the food can be burnt cleanly. Even if the mounting container becomes dirty, cleaning can be easily performed. Furthermore, the attached dirt itself has a heat insulating effect, so that there is no fear of adversely affecting the baking performance of the food.
[0017]
According to the seventh aspect of the invention, by providing the heating surface of the placing container with the uneven portion, a gap can be reliably formed between the food and the surface of the loading container, and the product comes out when the food is baked. Since the oil accumulates in the recesses, the oil can be prevented from re-adhering to the food and making the food oily.
[0018]
The invention according to claim 8 has a configuration in which the grill is placed directly on the container for storing the food, so that the oil discharged from the food is absorbed by the food again, and the food becomes oily. If the food becomes small or the food is placed directly on the mounting container, the contact area between the food and the heating means becomes large, so that it is possible to prevent the food from being scorched and becoming difficult to peel off. Further, when the food is placed directly on the mounting container and baked, a large amount of heat is absorbed by the contact portion, and heat is not supplied to the other portions, so that it is possible to prevent the baked food from being uniformly burned. Further, since radiant heat can be uniformly received from a certain distance, uniform heating can be performed.
[0019]
According to the ninth aspect of the present invention, the lower heating means and the upper heating means are provided, and the input of the lower heating means is made larger than the input of the upper heating means, and the lower heating means heats the mounting container by the main heating source. Therefore, a part of the heat supplied from the main heating source is taken by the temperature rise of the mounting container. Therefore, in order to supply heat more evenly from above and below the food, it is necessary to make the input of the lower heating means larger than that of the upper heating means, whereby the upper and lower surfaces of the food can be evenly baked. .
[0020]
In the invention according to claim 10, the size of the placement container and the main heating source, which are the lower heating means for placing the food, is set to be a size that the placement container covers at least the main heating source. The main heating source is not larger than the size of the placement container, and the heat of the main heating source is reliably transferred to the placement container, which is the lower heating means, so that heat can be efficiently transmitted to the food and cooking performance is improved. I do. Furthermore, since the heat of the main heating source is transmitted from the center of the mounting container to the outside, generally, heat can be efficiently supplied to the position where the food is placed, so that the cooking performance can be further improved. it can.
[0021]
【Example】
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0022]
(Example 1)
In FIG. 1, 1 is a heating cooker main body, and 2 is a heating plate 5 on which a cooker 4 for induction heating by a heating coil 3 is placed. The heating coil 2 has a space 5 for cooling, and a roaster section 6 is arranged below the space 5. A heating source 8 that can be heated in a thin planar shape, such as a mica heater or a print heater, is attached to the back side of the bottom surface of the cooking chamber 7 of the roaster unit 6. A placing container 9 placed on the heating source 8 is detachably provided in the cooking chamber 7, and the placing container 9 is heated by the heating source 8, so that the entire surface of the placing container 10 becomes a heating surface. The lower heating means 10 is constituted by. Further, an upper heating means 11 is provided in a space above the cooking chamber 7, and is constituted by a heating source such as a sheath heater which generates a large amount of radiant heat.
[0023]
Further, the placing container 10 can be taken out in conjunction with opening and closing of the opening and closing door 12 of the cooking chamber 7. The mounting container 9 is made of a high heat conductive material such as aluminum, and a heat-resistant adhesive material such as Teflon is applied to a heating surface. Reference numeral 13 denotes a grid placed on the mounting container 9, which is placed in a state close to the mounting container 9. Reference numeral 14 denotes an exhaust pipe provided at the rear of the cooking chamber 7 for discharging smoke and heat during cooking.
[0024]
In such a configuration, the cooking device 4 is placed on the heating plate 3 in the heating cooking device main body 1, a current is supplied to the heating coil 2, and a function of performing heating cooking by induction heating and a function of performing cooking such as fish grilling are provided. Roaster part 6 is incorporated. However, since the cooking function using the heating plate 3 is mainly used frequently, the roaster unit 6 is provided with a space 5 for cooling below the heating plate 3, the heating coil 2, and the like. Must be constructed in space. The roaster unit 6 opens the opening / closing lid 12, pulls out the mounting container 9, and places the food 15 such as fish on the grill 13.
[0025]
Thereafter, when the lid 12 is closed and the upper and lower heating means 10 and 11 are energized, the upper heating means 11 rises to about 600 ° C. in the case of a sheathed heater, for example, and the lower heating means 10 becomes 400 to 500 in the case of a planar mica heater, for example. ° C, and the surface of the mounting container 9 serving as a heating surface rises to 250 ° C to 300 ° C. Therefore, the food 15 is simultaneously heated from above and below. At this time, it is necessary to form the food 15 at a certain distance from the upper heating means in order to make it easier to store it in the cooking chamber 7. Therefore, the upper heating means 11 uses radiant heat from a relatively high-temperature sheath heater or the like. I have.
[0026]
However, the lower surface of the food 15 does not need to be separated from the heating surface, and it is better to be as close as possible to the heating surface in order to eliminate unnecessary space. Therefore, by using the relatively low-temperature planar heating, it is possible to heat the food close to the placing container 9 and in a planar manner, so that the cooked food can be evenly grilled even when approaching the heated surface. In addition, the height of the entire roaster section 6 can be suppressed to a significantly low level.
[0027]
Furthermore, according to this configuration, the space-saving roaster unit 6 can be configured with double-sided heating, even when the height is limited according to the height of a conventional gas range, such as the stationary cooking device 1, in particular. In addition, the cooking product 15 can be automatically baked until the cooking is completed. Further, the placing container 9 for the food 15 placed on the heating source 8 is directly heated by the heat source 8 by heat conduction, and the heat is efficiently transmitted. For this reason, since the entire mounting container 9 has a uniform and relatively low-temperature heating surface, even if the food is placed in close proximity, uneven grilling is not performed and uniform grilling can be performed. For this reason, the dimension between the lower heating means 10 and the food 15 can be significantly reduced, and the uniform heating can be performed, so that the baking performance can be improved.
[0028]
Furthermore, since cooking can be performed even when the surface temperature of the lower heating means 10 is relatively low, even if oil during cooking falls on the lower heating means 10, there is no risk of ignition and generation of oil smoke is reduced. Therefore, there is no need to provide a container containing water below the food, and it is not necessary to use extra heating energy for warming the water, so that less energy is required for cooking and energy is saved.
[0029]
In particular, since the mounting container 9 is made of a high heat conductive material such as aluminum, the heat transfer characteristic in the surface direction on the mounting container 9 is improved, and a uniform heating temperature is maintained regardless of the distribution and the location of the food. Even if the food is placed close to the heating surface of the mounting container 9, it can be evenly and evenly baked, so that the height dimension of the roaster unit 6 can be reduced, and further space saving can be achieved. The double-sided roaster unit 6 can be realized.
[0030]
Further, by configuring the main heating source with a planar heating element such as a mica heater or a print heater, the temperature distribution on the heating surface of the mounting container 9 becomes uniform even when the food 15 is placed directly on the mounting container 9. Therefore, the way of burning the food 15 can be evenly baked, and the heating source 8 itself can be made thinner, so that the lower heating means 10 can be made thinner and both-side heating can be performed in a space-saving manner.
[0031]
In addition, since the heating source 8 is formed of a sheathed heater, even if the heating source 8 is disposed inside the roaster section 6 in the cooking chamber 7, it is possible to maintain electrical insulation against moisture and oil from the cooking product 15 during heating. Further, the heating source 8 can be directly applied to the mounting container 9 for heating. Accordingly, there is no need to worry about insulation or the like, and the thermal efficiency can be increased. Therefore, heat can be supplied without being affected by the distribution and the placed position of the food 15, and the thin roaster section 6 can be configured safely. .
[0032]
Further, by providing the lower heating means 10 and the upper heating means 11 and configuring the upper heating means 11 with a sheathed heater, the surface temperature of the upper heating means 11 can be increased. Even if the distance from the upper heating means 11 is increased, the food can be baked sufficiently by radiant heat, and the food can be easily taken in and out of the cooking chamber, and a larger food can be baked.
[0033]
Further, by forming the placing container 9 from an adhesive material such as Teflon, the food 15 can be prevented from sticking to the surface of the placing container 9, and the surface of the food 15 can be burnt cleanly and can be used. Even if one mounting container 9 becomes dirty, cleaning can be easily performed. Furthermore, since the dirt does not stick, the dirt itself has a heat insulating effect, and it is possible to eliminate the fear of adversely affecting the baking performance of the food 15.
[0034]
Further, by adopting a configuration in which the grill 13 is placed directly on the loading container 9 for the food 15, the oil coming out of the food 15 is absorbed by the food 15 again, and the food 15 becomes oily. When the food 15 is placed directly on the mounting container 9, the contact area between the food 15 and the lower heating means 10 increases, so that it is possible to prevent the food 15 from being scorched and becoming difficult to peel off. Further, when the food 15 is placed directly on the mounting container 9 and baked, a large amount of heat flows to the contact portion, heat is not supplied to the other portions, the baked food is not evenly burned, and the food 15 becomes greasy. , Can be prevented from sticking to and detaching from the mounting container 9. In addition, since radiant heat can be uniformly received, uniform heating can be achieved.
[0035]
Further, the lower heating means 10 and the upper heating means 11 are provided, and the input of the lower heating means 10 is made larger than the input of the upper heating means 11, so that the lower heating means 10 Due to the heating configuration, a part of the heat supplied from the heating source 8 is taken by the temperature rise of the mounting container 9. Therefore, in order to supply heat more uniformly to the upper and lower sides of the food 15, it is necessary to make the input of the lower heating means 10 larger than that of the upper heating means 11, whereby the upper and lower surfaces of the food can be evenly baked. Things.
[0036]
(Example 2)
In FIG. 2, the placing container 9 has a configuration in which the heating surface is provided with the uneven portion 16, so that a gap is reliably formed between the cooking product 15 and the surface of the placing container 9, and the oil that is emitted when the cooking product is baked Since the oil accumulates in the uneven portion 16, oil can be prevented from re-adhering to the food 15 and the food 15 becoming oily.
[0037]
(Example 3)
In FIG. 3, the size of the placing container 9, which is the lower heating means 10 on which the food 15 is placed, and the size of the heating source 8 are set so that at least the heating source 8 is completely covered by the placing container 9. Since the source 8 is not larger than the mounting container 9 and the heat of the heating source 8 is reliably transmitted to the mounting container 9 as the lower heating means 10, the heat can be efficiently transmitted to the food 15 and the cooking performance is improved. I do. Further, since the heat of the heating source 8 is transmitted from the center of the mounting container 9 to the outside, the heat is generally supplied efficiently to the position where the food 15 is placed, so that the cooking performance can be further improved.
[0038]
【The invention's effect】
As described above, according to any one of the first to tenth aspects of the present invention, the placing container for the food placed on the heating source is directly heated by the heating source, and the heat is efficiently transmitted. For this reason, the entire mounting container has a uniform and relatively low-temperature heating surface, and even if the food is placed in close proximity, uneven grilling is not performed and uniform grilling is possible. And the dimension between the lower heating means and the food can be greatly reduced. Moreover, since the heating can be performed uniformly, the baking performance is also improved.
[0039]
Furthermore, since cooking is possible even if the surface temperature of the lower heating means is greatly reduced, there is no need to add water because there is no risk of ignition even if oil falls on the lower heating means, and there is less generation of oil smoke. This eliminates the need for extra heating energy, reduces the amount of energy required for cooking, and saves energy. As a result, even in a stationary cooker, the food can be heated from both sides simultaneously, and Automation is possible and usability is greatly improved.
