Description

  The present invention relates to a stationary type or built-in type heating cooker equipped with a grill room for storing cooked food that is used in a general household kitchen or a commercial kitchen.

  Conventionally, a general configuration around a general grill room in this type of cooking device is that a saucer is arranged in a roaster heating chamber, a grill net on which food is placed is mounted on the saucer, and the roaster heating chamber The mainstream is to heat the cooked food from the top and bottom both sides by placing heaters in the upper part and the space below the grilled food placing surface. Both sides can be baked without any problem (see, for example, Patent Document 1; in the above description, Patent Document 1 is used as the name of each part).

  In addition, although actual commercialization has not yet been realized at the present time, in recent technology, the upper heating body and the lower heating are added to the cooking chamber for the purpose of cooking thicker foods and improving the cleanability. The body is built in, a bottom plate is provided so as to cover the upper part of the lower heating body, a heating plate on which the food is placed is arranged, and the lower heating body is composed of a grill heating coil that performs induction heating. In addition, a configuration in which the cooking heating plate itself is induction-heated through the bottom plate is also considered (for example, refer to Patent Document 2, and in the above description, Patent Document 2 is used as the name of each part).

JP 2007-141651 A JP 2010-267422 A

  However, in the conventional general grill configuration, a heater is disposed between the saucer and the food, and if fat from the food drops on the lower heater and smokes, The amount of smoke that is discharged increases, causing increased dirt on the kitchen walls and the like, and odors on the interior of the room, and the smell of smoke attached to the cooked food deteriorates the aroma and taste. It was. In addition, when the spray splashed from the food during heating removes the dirt adhering to the wall surface of the heating chamber (the grill chamber in the present invention), the heater on the lower side becomes an obstacle and the cleaning performance is poor. Since it is dirty, it has a problem such as taking time and effort to remove it.

  On the other hand, in the configuration in which the heating plate (the grill pan in the present invention) is directly heated by induction heating which is a recent technique, the upper heating body and the lower heating body are built in the cooking chamber (the grill chamber in the present invention), A bottom plate is provided so as to cover the upper part of the lower heating body, a cooking heating plate is arranged on the bottom plate, and the lower heating body is configured as an induction heating coil. It is necessary to form the bottom plate interposed between the coil and a material that is not induction-heated.

  Here, conventionally, the members constituting the cooking chamber are generally composed of steel plates subjected to enamel processing from the comprehensive viewpoint of heat resistance, cleanability, cost, etc., but the steel plates are induction heated. So this cannot be used for the bottom plate.

In this case, it is desirable to use a material excellent in heat resistance, wear resistance, cleanability, etc. for the bottom plate, for example, crystallized glass. However, crystallized glass itself is a process for mounting due to the characteristics of the material. For example, it is difficult to form a fastening hole and assemble by fastening with a screw or the like, and it is necessary to fix with an adhesive sealant or the like, or fix with another member. In order to improve the appearance, it is necessary to prevent them from being exposed in the cooking chamber.

  However, since the bottom plate is fitted into the cooking chamber, it is difficult to seal or fix the bottom plate from the lower surface side, and it is difficult to check the mounting state after the bottom plate is attached.

  In addition, the heating coil generates heat in addition to the coil itself. In such a configuration, the upper surface of the heating coil receives the heat of the heating plate, which is the object to be heated, and the temperature rises. However, it is necessary to cool the heating coil to a temperature at which there is no problem in use. However, in the above configuration, the heating coil is confined in the cooking chamber by the bottom plate that separates the heating plate and the heating coil. Therefore, the heating coil itself has a problem of heat radiation, and it is difficult to form an air supply / exhaust path when forcibly cooling with a cooling fan or the like (in the above description) The names of each part are the same as those of each patent document).

  The present invention solves the above-mentioned conventional problems, and significantly reduces the smoke generated by dripping on the heater, such as the fat content from the cooked food during cooking, improving the workmanship of the cooked food and the contamination of the room. Heating equipped with a grill function that can be reduced, dramatically improves the cleanability of the grill room, shortens the cooking time, further simplifies the configuration and improves reliability, etc. The purpose is to provide a cooker.

In order to solve the above-described conventional problems, a heating cooker according to the present invention includes a main body, a grill chamber disposed in the main body and having a front opening and a bottom portion, and a grill covering the front opening of the grill chamber. A door, a grill pan that is detachably disposed in the grill chamber, and on which the food is placed, first heating means for heating the food from above, and second heating for heating the food from below And the second heating means includes a grill heating coil that performs induction heating, and is provided outside the grill chamber and below the grill chamber. A coil support member that is partially formed of a material that is induction-heated, and that the bottom portion of the grill chamber is at least partially formed of a material that is not easily induction-heated, and mounts and supports the grill-heating coil. More Together with, the outer shape of the coil support member is in the shape covering most of the bottom portion of the grill chamber, and extending the coil support member, or by joining said coil supporting member and another member Thus, a heat shield case that covers the outer surface of the grill chamber is formed, and at least a bottom surface and a side surface of the grill chamber are covered by the heat shield case .

  With this configuration, the grill pan is formed of a material that is induction-heated and is detachably disposed in the grill chamber, and the second heating means for heating the food from below is used as a grill heating coil that performs induction heating in the grill chamber. By separating the food placed on the grill pan and the grill heating coil from the bottom of the grill chamber, only the detachable grill pan is provided at the bottom of the grill chamber. There is no such thing, and the cleanability is greatly improved. Of course, the cooking can be efficiently heated by heating the grill pan itself on which the food is placed by the grill heating coil. Time can be shortened.

  At this time, the grill pan is configured by combining a material that can be easily induction-heated and a material that has good heat conduction, so that the entire grill pan can be uniformly heated during heating, and uneven baking of the cooked food can be reduced.

Further, by eliminating the bottom plate in the prior art as shown in Patent Document 2, the grill chamber can be made into a simple box shape, so that the configuration of the grill chamber can be simplified, for example, the bottom portion of the grill chamber is Due to the reasons mentioned above, it is made of crystallized glass, and other parts are made of steel plate that has been subjected to enamel processing. For example, when fixing the bottom surface made of crystallized glass to the other grill chamber portion by another member for fixing, such as adhesive fixing with an adhesive sealant or the like, the back surface is almost Since it is completely exposed, it is easy to work from the back side, that is, from the outside, and it is easy to check the finished state after installation.

  Furthermore, it is easy to provide a gap between the bottom surface of the grill chamber and the top surface of the grill heating coil by disposing a coil support member that mounts and supports the grill heating coil provided below the grill chamber. When cooling the top surface of the grill heating coil that receives heat from the grill pan that is heated by induction, it does not interfere with the heat dissipation of the grill heating coil itself, and when it is forcibly cooled by a cooling fan, etc. However, it is easy to form the air supply / exhaust path, and the temperature rise of the grill heating coil can be suppressed to ensure reliability and durability.

According to the heating cooker of the present invention, it is possible to drastically reduce the smoke generated by dripping onto the heater, such as the fat content from the cooked food during cooking, and to improve the quality of the cooked food and reduce indoor dirt. Further, it is possible to achieve a grill function that greatly improves the cleanability of the grill chamber, shortens the cooking time, and further simplifies the configuration and improves the reliability for realizing these. In addition, the coil support member can be provided with a heat shielding function for blocking downward heat from the grill chamber, the grill heating coil, and the like, and the number of parts can be reduced. In addition, the coil support member can be provided with a heat shielding function for blocking downward heat from the grill chamber, the grill heating coil, and the like, and the number of parts can be reduced. Further, since the coil support member can be used as a part of the heat shield member, it is reasonable to save the member.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments. Here, the description order of the embodiments may be different from the order of the invention described above. In some cases, a plurality of inventions are comprehensively described.

(Embodiment 1)
FIG. 1 is an assembly cross-sectional view in the front-rear direction showing a schematic configuration of the heating cooker according to the first embodiment of the present invention. FIG. 2 is an assembled cross-sectional view in the left-right direction showing the main part of the cooking device according to the first embodiment of the present invention.

  However, components that are not necessary for the description of the embodiment are omitted even if they are main components. Hereinafter, it demonstrates using drawing.

  On the top surface of the main body 1, a top plate 2 on which a cooking utensil such as a pan is placed is arranged. The heating method of the cooking utensil such as a pan in this embodiment is electromagnetic induction heating, and the top plate 2 is made of a material that is not heated by electromagnetic induction, such as highly heat-resistant crystallized glass, Below the top plate 2, a top surface heating coil 3 that performs induction heating is provided in the vicinity.

  Here, the heating method of the cooked utensil placed on the top plate 2 is not limited to the electromagnetic induction heating method, and may be, for example, an electric resistance heater using a nichrome wire.

  Although not shown, the top surface heating coil 3 is supplied with high-frequency power by a power supply circuit. A grill chamber 4 having a substantially box shape and having a front opening portion and a bottom surface portion is disposed in the main body 1, and the opening is covered with a grill door 5 that is movably attached in the front-rear direction. .

  One end of an exhaust tube 6 for discharging smoke generated in the grill chamber 4 to the outside of the main body 1 is connected to the rear portion of the grill chamber 4, and the other end of the exhaust tube 6 is connected to the opening of the top plate 2. In the grill chamber 4, a grill pan 8 on which the food 7 is placed is stored.

  Above the grill chamber 4, first heating means (hereinafter referred to as grill heating means 9) for heating the food 7 from above is arranged, and a large number of parts formed on the ceiling surface 10 of the grill chamber 4. The food 7 is heated by radiant heat through the hole 11.

In the present embodiment, the grill heating means 9 is a resistance type heater incorporating a nichrome wire, but other types of heating means may be used and the present invention is not limited to this.
□ Outside the grill chamber 4 and below the grill chamber 4 is a grill heating coil 13 (hereinafter referred to as a grill heating coil 13) that performs induction heating as a second heating means for heating the food 7 from below. The grill pan 8, which is detachably disposed in the grill chamber 4, directly heats the grill pan 8 across the bottom surface portion 14 of the grill chamber 4 (the principle of induction heating is well known). Therefore, the description is omitted).

  The bottom surface portion 14 of the grill chamber 4 is made of crystallized glass that is a material that is not induction-heated and has excellent heat resistance, wear resistance, cleanability, and the like.

  In the present embodiment, the entire bottom surface portion 14 is formed of crystallized glass, and the size of the bottom surface portion 14 made of crystallized glass, which is this separate member, is at least in a range relative to the grill heating coil 13, that is, grill heating. The coil 13 is set to be larger than the range projected vertically upward.

  Further, if the crystallized glass constituting the bottom surface portion 14 has a certain size, the entire area of the bottom surface portion 14 is not induction-heated. For example, the bottom surface portion 14 is divided into coils. The upper portion may be made of crystallized glass, and the other portion may be made of a steel plate subjected to enamel treatment.

  Here, the grill pan 8 is formed on the back surface of a grill pan main body 11 made of aluminum die cast having excellent heat conductivity, and is a magnetic material that is induction-heatable and has corrosion resistance, such as ferritic stainless steel represented by SUS430. The surface of the grill pan body 11 is subjected to fluororesin processing in order to improve non-adhesiveness and corrosion resistance with respect to the cooked food.

  The grill pan 8 is alternately provided with a convex portion 15 that contacts the food 7 and forms a mounting surface, and a concave portion 16 that isolates the fat content from the food 7 from the food 7 and prevents reattachment or the like. Is formed.

  The crystallized glass forming the bottom surface portion 14 of the grill chamber 4 is sandwiched and fixed together with the flange 19 formed on the side surface portion 18 of the grill chamber 4 by the fixing member 17 to form the substantially box-shaped grill chamber 4. ing.

  The gap between the inside of the flange 19 of the side surface portion 18 of the grill chamber 4 and the end surface of the bottom surface portion 14 of the grill chamber 4, that is, the end surface of the crystallized glass, is cured after application to adhere both and maintain watertightness. It is buried from the lower outside of the grill chamber 4 by a sealing material 20 that performs a sealing function.

  Here, since the sealing material 20 used for filling the gap has a similar effect even when a material having an elastic material, such as packing, is fitted in the sealing portion in advance, the same effect can be obtained. The method and specification of the sealing material 20 are not limited by the embodiment.

  A notch 21 formed in the front portion of the grill pan 8 is fitted to an arm 22 attached to the grill door 5 and can move in the grill chamber 4 in conjunction with the movement of the grill door 5. It is like that.

A sliding member 23 is attached to the rear lower surface of the grill pan 8. When the grill pan 8 is moved, only the sliding member 23 is in sliding contact with the bottom surface portion 14 of the grill chamber 4, and the coating film on the surface of the grill pan 8 is rubbed. This prevents it from being peeled off. That is, the entire grill pan 8 is accommodated in the grill chamber 4 with a clearance from the bottom surface portion 14 of the grill chamber 4 by the support by the sliding member 23 and the fitting to the arm 22. When the grill pan 8 is configured not to directly contact the bottom portion 14 of the grill chamber 4 in this manner, the bottom portion 14 can be cooled by direct heating of the grill pan 8 by induction heating. The bottom surface portion 14 can be further cooled by the heat insulating effect due to the gap. Therefore, the bottom surface portion 14 does not become hotter than before, and the safety and user care can be improved.

  When the food 7 is heated from below by the grill heating coil 13, the heat of the heating element 12 of the grill pan 8 induction-heated by the grill heating coil 13 is transmitted to the grill pan main body 11, and the heat is transferred to the grill pan 8 by the heat. The placed food 7 is cooked by heating.

  The grill heating coil 13 is placed on a coil support member 24 disposed below the grill chamber 4 via a shield member 25, whereby the grill heating coil 13 is supported at the lower portion thereof. It is arranged at a predetermined position with a certain gap between it and the bottom surface portion 14.

  Here, the shield member 25 is formed of a heat-resistant nonmagnetic conductive material such as aluminum, and is disposed to block the magnetic flux of the grill heating coil 13, and is generally relatively inexpensive such as a plated steel plate. The coil support member 24 formed of a simple material is prevented from being induction-heated by the grill heating coil 13.

  Further, the outer shape of the coil support member 24 covers most of the bottom surface portion 14 of the grill chamber 4 and is fixed to the grill chamber 4 from the outside. That is, the coil support member 24 supports the grill heating coil 13 and simultaneously supports the grill chamber 4.

  Here, as the fixing method of the grill chamber 4 and the coil support member 24, various methods that have been widely used in the past, such as fastening with screws, engagement between the claw and the hole, and spot welding, can be considered. Is not particularly defined, and it is only necessary to maintain the positional relationship between the coil support member 24 and the grill chamber 4 after the product is completed. The position of the grill chamber 4 and the coil support member 24 may be regulated by being sandwiched between peripheral members.

  That is, “fixed” in the present invention means that the relative positional relationship between the two is maintained. Therefore, as for the fixing method of both, an appropriate one may be selected in accordance with the actual situation, so that the description of the specific configuration is omitted here. Further, in fixing both, either the grill chamber 4 or the coil support member 24 may be the fixed side or the fixed side.

  With the configuration as described above, the grill pan 8 on which the food 7 is placed is made of an aluminum die-cast grill pan main body having good heat conduction with the heating element 12 formed of a material capable of induction heating such as ferritic stainless steel. 11 and is detachably disposed in the grill chamber 4 and a grill heating coil 13 for heating the grill pan 8 is disposed below the grill chamber 4 so as to be placed on the grill pan 8 and the grill pan 8. By separating the cooked food 7 and the grill heating coil 13 from the bottom surface portion 14 of the grill chamber 4, if the grill pan 8 detachably arranged with respect to the grill chamber 4 is removed, the lower portion in the grill chamber 4 is obstructed. As a result, the grill pan 8 itself on which the food 7 is placed is heated by the grill heating coil 13 so that the cooking 7 is efficiently heated. Can go to In, it can be shortened and energy-saving cooking time.

  Further, the grill pan 8 is composed of a heating element 12 formed of a material that is easily induction-heated and a grill pan main body 11 formed of a material with good heat conduction, so that the entire grill pan 8 is heated at the time of heating. Can reduce the unevenness of cooking, and greatly improve the quality of cooking.

  Moreover, since the grill chamber 4 can be made into a simple box shape by eliminating the bottom plate in the prior art as shown in Patent Document 2, in addition to simplifying the configuration of the grill chamber 4, for example, the grill chamber 4 is formed of crystallized glass for the above-mentioned reasons, and other portions are formed of steel plate subjected to enamel processing. Due to the material properties of the crystallized glass, holes for fastening are applied. Since it is difficult to directly fasten it to the mating member, the flange 19 of the grill chamber 4 and the crystallized glass as the bottom surface portion 14 are sandwiched and fixed using the fixing member 17 as in the present embodiment. In doing so, the back surface is almost completely exposed, so that the work from the back surface, that is, the outside is easy to perform, and it is easy to check the state after mounting.

  Furthermore, by placing the grill heating coil 13 provided below the grill chamber 4 and arranging a coil support member 24 for supporting the grill heating coil 13, the bottom surface portion 14 of the grill chamber 4 and the upper surface of the grill heating coil 13 are arranged. When the top surface of the grill heating coil 13 that receives heat from the grill pan 8 that generates heat by induction heating is cooled, the heat radiation of the grill heating coil 13 itself is not hindered. Even when the cooling fan is forcibly cooled, the air supply / exhaust path can be easily formed, the temperature rise of the grill heating coil 13 can be suppressed, and the reliability and durability can be ensured.

  However, even when heat radiation from the grill heating coil 13 is not required, the distance between the bottom surface portion 14 of the grill chamber 4 and the grill heating coil 13 mounting surface of the coil support member 24 is set to be equal to that of the grill heating coil 13. By setting the dimension of the maximum thickness variation with some allowance, an excessive pressing force is not applied to the surface of the grill heating coil 13, so that there is no possibility of damaging the coating of the grill heating coil 13.

  In addition, the grill chamber 4 has a bottom portion 14 in which at least a range corresponding to the grill heating coil 13 is formed of a separate member, and the bottom portion 14 is sealed by a sealing material 20 and joined. By forming the chamber 4, it is possible to secure water tightness around the bottom surface portion 14 of the grill chamber 4, so that the moisture and fat content of the food 7 accumulated on the grill plate 8 can be accidentally spilled into the grill chamber 4. , It can be prevented from leaking out of the grill room 4 and soiling the kitchen, etc., or adhering to the electrical components inside the equipment and causing malfunctions, but it ensures water tightness in a relatively simple box-shaped grill room. At that time, since the watertightness required for the whole grill apparatus is obtained, the reliability at the time of assembly is high.

  Here, as the sealing material 20, a seal member that is cured after being applied to a seal portion, such as an adhesive sealant, or a seal material that is preliminarily shaped with an elastic material, such as packing, is sealed. Various methods, such as fitting in place, can be considered, but an appropriate sealing method may be used according to the actual situation, and is not limited thereto.

  Further, since the bottom surface portion 14 of the grill chamber 4 is sealed and joined from the outside of the grill chamber 4, for example, the sealing material 20 is composed of an adhesive sealant that hardens after application to the above-described seal portion and forms a seal member. In the case of application from the inside of the grill chamber 4, especially the rear portion of the grill chamber 4 is difficult to work due to the ceiling portion being obstructed, and the confirmation of the finish tends to be insufficient. By joining, these problems can be solved, and the reliability of assembly can be improved. Further, the inside of the grill chamber 4 is a portion that can be cleaned by the user and can be visually observed during use. Sexual deterioration can be prevented.

  Further, since the outer shape of the coil support member 24 is configured to cover most of the bottom surface portion 14 of the grill chamber 4, the coil support member 24 itself is provided with the grill pan 8 in the grill chamber 4, the grill heating coil 13, and the like. It is also possible to provide a heat shielding function for shielding downward heat, so that it is not necessary to add a new heat shielding member, and parts can be reduced.

  Further, since the coil support member 24 is fixed to the grill chamber 4 from the outside of the grill chamber 4, the coil support member 24 can support the grill chamber 4 from below, so that the coil heating member 13 is supported by the coil support member 24. By supporting both the grill chamber 4 and the grill chamber 4, the accuracy of the distance between the grill heating coil 13, which is important in the induction heating method, and the heating element 12 of the grill pan 8 that is a heated object placed in the grill chamber 4 is improved. And the stable heating by the grill heating coil 13 becomes possible.

(Embodiment 2)
FIG. 3 is an assembled cross-sectional view in the front-rear direction showing a schematic configuration of the heating cooker according to the second embodiment of the present invention. FIG. 4 is an assembled cross-sectional view in the left-right direction showing the main part of the heating cooker according to the second embodiment of the present invention.

  Here, since the configuration other than the configuration specific to the second embodiment is the same as that of the first embodiment, the description thereof will be omitted.

  A shielding member 26 is disposed outside the grill chamber 4 so as to cover the top surface, the rear side, and the left and right side surfaces of the grill chamber 4. The coil support member 27 and the shielding member 26 are joined to each other. A heat shielding case 28 having a substantially box shape to cover and having an open front is configured.

  The grill heating coil 13 is supported by a coil support member 27 that forms the bottom surface of the heat shield case 28. The coil support member 27 is made of aluminum, which is a nonmagnetic conductive material that is difficult to be heated by induction heating at a high frequency that is normally used.

  Here, the shielding member 26 covers the upper surface, the rear side, and the left and right side surfaces of the grill chamber 4. However, for example, when not much heat shielding is required above the grill chamber 4, only the rear and left and right side surfaces of the grill chamber 4 are covered. It may be covered.

  With the configuration as described above, the coil support member 27 can be used as a part of the heat shield member. Therefore, it is reasonable to eliminate the waste of the member, and the product can be reduced in size and weight.

  Further, by making the heat shield case 28 into a substantially box shape, the rigidity is increased. As a result, the strength is increased against an unexpected impact external force due to a drop or the like during transportation, and damage to the product can be prevented.

  Since the magnetic metal member adjacent to the back surface of the grill heating coil 13 can also serve as a shield member for preventing erroneous heating, the dead space below the grill heating coil 13 and parts can be reduced. Can be made smaller and lighter.

  As described above, the heating cooker according to the present invention has a simple configuration and greatly reduces the fuming caused by dripping onto the heater, such as fat from the cooked food during cooking. The grill function is designed to improve the cleanability of the grill room, shorten the cooking time, and simplify the configuration and improve the reliability to achieve these. Since it can be realized, it can be widely applied not only to stationary or built-in heating cookers used in general household kitchens or commercial kitchens, but also to other forms of cooking cookers.
