Description

  The present invention relates to an induction heating cooker including a grill that uses induction heating as a heat source.

  2. Description of the Related Art Conventionally, a roaster (hereinafter referred to as a grill warehouse) provided in an induction heating cooker (hereinafter referred to as IH cooking heater) is provided with electric heaters on the upper and lower sides of an object to be cooked such as fish, and both surfaces are heated simultaneously. It is common. A sheathed heater or the like is used as an electric heater of the grill cabinet. The sheathed heater is provided exposed in the cabinet, and heats the object to be cooked by radiant heat from the heater surface that is at a high temperature.

  In addition to heating fish etc. with the radiant heat of an electric heater in this grill chamber, it is possible to control heating by controlling the temperature in the chamber, so that it can respond to various cooking menus such as pizza, sweets, cakes, etc. . As a result, the increase in the frequency of use overlaps, causing a new problem that the inside of the cabinet is easily soiled.

  Many grills for grilling fish use the deodorizing / desmoking effect of thermal catalysts to reduce odors and oily smoke generated during cooking, and measures are taken to prevent the surrounding air from becoming dirty. On the other hand, cleaning of oil and oil splashed in the chamber includes cleaning control that temporarily raises the chamber temperature to burn off the dirt, and a configuration that generates steam to elute the dirt so that the dirt can be easily wiped off. It has been.

  As a conventional technique of such a grill cabinet, Patent Document 1 discloses a roaster that uniformly cooks an object to be cooked by generating heat on a heating plate using induction heating instead of a sheathed heater.

  Further, Patent Document 2 discloses that a cooking tool is placed on the top plate of the IH cooking heater and the heating box of the cooking tool is heated by induction heating.

  Patent Document 3 discloses a pottery cooker that is used by being placed on a top plate of an IH cooking heater. This pottery cooker uses the induced electromotive force generated through the coupling coil, induces the electromagnetic energy of the heating coil of the IH cooking heater to a remote heater, generates heat, and heats the object to be cooked through the radiant heat transmission plate. To do.

On the other hand, there is Patent Document 4 as an example of improving the cleanability of the inside of the grill cabinet built in the IH cooking heater. In this case, a cubical indoor cover is slidably placed in the cabinet so that it can be removed and washed even when oil is scattered and burned.
Alternatively, Patent Document 5 discloses one in which a roaster case (grill box) can be taken in and out of the main body.

Japanese Patent Laid-Open No. 9-75233 Japanese Utility Model Publication No. 63-69397 Japanese Patent Laid-Open No. 11-204243 JP-A-6-209865 JP-A-2005-212256

  A conventional grill cabinet is generally provided with an electric heater exposed in the cabinet, and an object to be cooked placed on a grill at a position opposite to the electric heater that generates heat is generally baked by radiant heat from the electric heater.

  However, since this conventional grill warehouse heats a to-be-cooked object from both the upper and lower sides, an electric heater arranged at the lower position of the to-be-cooked object has a structure protruding near the center of the interior. Accordingly, the gap between the electric heater at the lower position and the storage wall is narrowed, and it is difficult to reach the inner side of the storage room, so that the interior cleaning performance is lacking.

  In addition, the grill warehouse provided in the IH cooking heater has a limited storage capacity in the kitchen, the interior height is as low as about 10 cm, and the height at which the food can be placed is the upper side exposed in the interior. Because it is a narrow space between the electric heater and the grill, it is impossible to cook a tall object to be cooked in the cabinet.

  In patent document 1, it has the structure where the fats and oils and water | moisture content of to-be-cooked material are dripped directly at the heating plate above a heating coil. For this reason, oil and fat and scattered debris are likely to accumulate on the heating plate and easily become dirty, and if the heating plate becomes hot, it may cause ignition. In addition, since a specific heating plate holding structure is not described, if there is not enough space below the heating plate, the heating plate is soaked with oil or moisture from the food to be cooked, and the heating plate is deprived of heat. This will prevent the cooking object from being heated.

  Patent Document 2 is a cooking utensil using an IH cooking heater and, like a pan heated on a top plate, heats the container (heating box) itself of the cooking utensil itself, so that only one side of the container is radiantly heated. It will be.

  In other words, as with a general pot, the user must decide how to use it and how long it will take. For this reason, for example, the user has to use it only for the user's judgment in terms of safety such as burns of the user and ignition by oils and fats from the food to be cooked. In addition, the cooking state such as heating power and heating efficiency is changed by the combination of the IH cooking heater in which the cooking utensil is used, so that the cooking finish is not stable.

  Similarly to Patent Document 2, Patent Document 3 is an accessory container for the IH cooking heater, and a radiant heat transmission plate provided above the heater serves as a surface for receiving boiled juice and oil from the object to be cooked. For this reason, heat energy due to radiant heat between the object to be cooked and the heater is blocked, and there is a risk of ignition of the oil and fat overheated by the radiant heat. In addition, in the radiant heat transmission plate structured so that it can be removed and washed, the oil component permeates through the gaps between the plates and enters the vicinity of the coupling coil. Further, when the radiant heat transmission plate is removed, the user directly touches the coupling coil, and there is a risk of electric shock if foreign matter is mixed in the vicinity of the coupling coil.

  In the structures of Patent Document 2 and Patent Document 3, it is not necessary for a general IH cooking heater provided with a grill (roaster), and it is desirable to improve the ease of use and cleaning of the conventional grill.

  Patent Document 4 and Patent Document 5 have a structure in which only the inner wall of the grill cabinet is removed, and oil and dirt scattered in a minute gap generated on the inner wall of the grill cabinet are likely to be mixed, and oil smoke and odors may be generated during cooking. Absent. Further, in the structure in which the sheathed heater is exposed in the chamber, the inner wall surface that holds the sheathed heater, for example, the inner rear surface of the chamber, cannot be removed, so it is difficult to wipe off the entire interior of the chamber.

  Therefore, in Patent Documents 4 and 5, the sheathed heater cannot be removed, the heater surface cannot be cleaned of dirt and dust, and in the case of a narrow grill warehouse such as an IH cooking heater, it is exposed in the cabinet. The heated heater gets in the way, making it difficult to get into the interior of the cabinet and cleaning it easily.

  The objective of this invention is providing the IH cooking heater provided with the grill | emission warehouse which can take out and clean the heating plate used as high temperature easily.

  The purpose is to place a top plate on which the cooking pan on the top surface of the main body is placed, a heating coil provided below the top plate, a grill box disposed below the heating coil, and the inside of the grill box A door for putting the food to be taken in and out, a grill for placing the food to be cooked, a saucer for placing the grill and interlocking with the door and housed in the cabinet together with the food to be cooked, and the saucer And an induction overheating cooker that is provided between the grill and the heating net and that heats the food to be cooked, and a lower heating coil attached to the bottom of the casing constituting the grill box, A plate attached to the upper part of the lower heating coil, and when the door is closed, the grill and the saucer are located on the upper part of the plate, and the heating means is between the saucer and the grill. That is accomplished by a heating plate mounted slidably.

  Also, the object is to place the grille on the tray that can be pulled out in conjunction with the door, and to allow the heating plate to slide to a height position in the cabinet that is a gap between the grille and the tray. This is achieved by providing a supporting storage shelf.

  Further, the object is to arrange the tray below the grill cabinet, and the tray and the grill net can be pulled out in conjunction with the door, and the inside of the cabinet serving as a gap between the grill net and the bottom of the grill cabinet. This is achieved by providing a storage shelf that slidably supports the heating plate at a height position.

  Further, the above object is achieved by providing a substrate for switching and controlling driving of a heating coil for heating the heating plate and driving of an induction heating coil for heating the cooking pan.

  The above object is achieved by providing temperature control means for detecting the temperature of the heating plate.

  The above object is achieved by providing an installation detecting means for determining the presence or absence of the heating plate placed on the storage shelf of the grill cabinet.

  ADVANTAGE OF THE INVENTION According to this invention, the IH cooking heater provided with the grill warehouse which can take out the heating plate used as high temperature easily and can clean it can be provided.

  Hereinafter, a built-in type IH cooking heater having a grill cabinet will be described as an example of the IH cooking heater of the present invention, but this embodiment can be applied to any cooking heater having a grill cabinet.

  By the way, in particular, grilled fish is generally preferred to grill directly over charcoal. This is considered to be due to the effect of far-infrared rays and the improvement of taste due to moderate burns. For this reason, there is a strong demand that the grill warehouse mounted on the IH cooking heater be as close to direct-fired as possible. For this reason, in a general grill cabinet, radiant heating is performed by placing fish on a grill net spaced a predetermined distance from the sheathed heater.

  However, as a matter of course, fish drips from the fish itself, and there is a problem that the oil drops on the sheathed heater and becomes dirty. However, since this sheathed heater is structurally fixed to the IH cooking heater, it cannot be removed and cleaned.

  On the other hand, the example which puts the iron plate used as a heater on an induction heating coil like patent documents 1-3, for example, and this iron plate becomes a kind of heater and the food is heated is disclosed. Even in such a heating system, oil from fish drops on the iron plate serving as a heater. However, Patent Documents 1 to 3 do not consider cleaning of the iron plate.

  Therefore, the inventors of the present invention have studied various structures that facilitate the removal of an iron plate that serves as a superheater and improve the cleaning performance, and have obtained the following examples.

  An embodiment of the present invention will be described below with reference to FIG.

FIG. 1 is a perspective view of a grill cabinet provided with a first embodiment of the present invention.
In FIG. 1, this figure shows the single body of the grill store | warehouse | chamber 1 mounted in an IH cooking heater. A state in which the tray 14 on which the heating plate 12 and the grille 15 are placed is pulled out to the front side of the IH cooking heater main body together with the door 19 inside the grill cabinet 1 is shown.

  FIG. 2 is a perspective view of the IH cooking heater provided with the first embodiment of the present invention.

  2, this figure shows a state in which the top plate 9 is removed from the induction heating coil 22, and the substrate case 5 has the induction heating coils 22 and 22a and a substrate 51 for supplying a high frequency current to the induction heating coil. Is installed.

  FIG. 3 is a side sectional view of the grill cabinet provided with the first embodiment of the present invention.

  In FIG. 3, this figure shows the state in which the food 99 is placed on the grill 15 in the grill 1 of the IH cooking heater. That is, the grill cabinet 1 shown in FIG. 1 is provided on the left side as viewed from the front of FIG.

Mainly using FIG. 1, the structure of the grill warehouse 1 of this invention is demonstrated.
1 to 3, the grill cabinet 1 formed of a metal box is opened and closed by sliding it in the front-rear direction of the main body for loading and unloading a food 99 such as fish, meat and pizza on the front side. A free door 19 is provided. The to-be-cooked object 99 is placed on the grill 15 such as a wire mesh.

  An upper heater 11 that is an electric heater is disposed on the upper side in the grill cabinet so as to be exposed in the cabinet. In addition, a lower heating coil 13 is attached to the lower side via a table 18 below the inside of the cabinet.

  The table 18 may be made of a material that transmits electromagnetic waves, such as glass. In this embodiment, the outer periphery of the table 18 is fixed to the bottom surface of the grill cabinet with silicon rubber (not shown). The table 18 itself may be removed and washed. Needless to say, if it is detachable, the cleaning property will be further improved. However, since dust and the like easily enter the gap between the table 18 and the storage wall, the table 18 provided so as to cover the lower heating coil 13 can be fixed. desirable.

  Further, a mica plate or the like may be used as the table 18 and may be fixed to the bottom surface of the grill cabinet with, for example, screws. In this embodiment, the winding shape of the lower heating coil 13 is rectangular according to the internal shape, but it may be a circular shape that can be easily wound, or may be divided into a plurality of parts. However, since it becomes difficult for the heating plate 12 to be induction-heated in a portion where the lower heating coil 13 is not provided, it is better to wind the coil so as to cover the entire lower surface inside the cabinet.

  Here, the heating plate 12 is a magnetic metal plate with good induction heating, such as iron, and a plate thickness of about 1 to 5 mm is suitable. When the heating plate 12 to be induction-heated is thick, the heat capacity increases and the temperature rise rate of the heating plate 12 becomes slow, so the performance as a heat source deteriorates. Is desirable.

  It can be said that a storage shelf 1a is formed on the inside of the grill cabinet 1 of the present invention so as to protrude to the inside of the cabinet. The heating plate 12 is configured to slide in and out from the front side along the storage shelf 1a. Here, although the storage shelf 1a may be provided horizontally in the cabinet, it may be held by unevenness or depressions in order to determine the position of the heating plate 12 in the depth direction. By determining the mounting position of the heating plate 12 to some extent, it becomes easier to confirm whether the heating plate 12 is installed, and a constant part temperature can be detected when detecting the temperature. Moreover, after removing the heating plate 12 from the interior and cleaning it, the mounting position can be prevented from being displaced even when the heating plate 12 is attached to the interior.

  In addition, a receiving tray 14 that moves following the door is provided on the door 19 where the cooking object 99 is taken in and out, and a grill net 15 on which the cooking object 99 is placed is placed on the receiving tray 14. Here, since the storage shelf 1a is provided so that the heating plate 12 is a gap between the tray 14 and the grill net 15, the heating plate 12 is below the cooking object 99. Located in.

  Therefore, the heating chamber 12 and the upper heater 11 serving as an electric heater using radiant heat or the like are provided in the grill cabinet 1 so as to be sandwiched between the upper and lower portions of the cooking object 99 while maintaining a predetermined distance. In addition, a saucer 14 is attached below the heating plate 12, and this saucer receives fat and moisture that fall from the cooking object 99.

  That is, the heating plate 12 is provided with the opening 12a, and by reducing the portion that becomes the cross between the openings 12a, the fat and water falling from the cooking object 99 are difficult to hit and the structure is difficult to accumulate on the surface. It has become. The main cause of the generation of oily smoke due to fats and oils is that the fat and water falling from the object to be cooked 99 collide with the surface of the heating plate, so by making it into a slit shape or a net shape like the structure of this embodiment, Generation of oil smoke can be suppressed. In addition, the opening 12a has a fine pitch, and if the opening ratio with respect to the heating plate 12 is made small, a heating surface will become wide and it will become easy to heat the to-be-cooked object 99 uniformly. However, the wider the heating surface, the easier it is for the fallen oil and fats to come into contact with each other, and the design is based on the trade-off between heating performance, generation of oil smoke, and ease of storage.

  In addition, temperature control means 30 for detecting the temperature of the heating plate 12 placed on the storage shelf 1 a is provided in the grill cabinet 1. Here, the temperature control means 30 may project a temperature sensor such as a thermistor on the inner wall of the cabinet so as to directly contact the heating plate 12, or an infrared sensor that can measure the temperature in a non-contact manner, for example. . In order to detect the temperature by contact, a temperature sensor may be provided on an elastic body such as a spring.

  Further, an installation detecting means 31 for determining whether or not the heating plate 12 placed on the storage shelf 1a has been placed at the original position of the storage shelf 1a is provided in the grill cabinet. Here, the installation detection unit 31 may be a switch that is turned on and off by contact, or may be, for example, an optical sensor that detects the presence or absence of a storage tray without contact.

  The temperature control means 30 and the installation detection means 31 can easily adjust the temperature of the heating plate 12 according to the food to be cooked, and energize the lower heating coil 13 of the grill cabinet 1 with the heating plate 12 taken out. The heating plate 12 can be safely attached and detached. Therefore, even if the heating plate 12 is attached and detached and the inside of the cabinet is cleaned, it can be easily returned to the original state after cleaning.

  The grill cabinet 1 is provided with an exhaust duct 10 for discharging oil smoke and steam in the cabinet at the upper rear side, and exhausts from an exhaust port 9b provided behind the communicating top plate 9. Here, the exhaust duct 10 may be provided with a catalyst for performing smoke removal and deodorization treatment, or an exhaust fan or the like may be separately provided in the route of the exhaust duct 10.

  Next, the internal configuration of the IH cooking heater in which the grill 1 is stored will be described mainly with reference to FIG.

  On the top surface of the main body of the IH cooking heater, there are provided a top plate 9, an intake port 9a and an exhaust port 9b for allowing air inside and out of the main body to enter and exit, and an operation unit 61 for operating the cooking pot. The exhaust port 9b is the same as the exhaust port of the grill 1 shown in FIG.

  Below the top plate 9, induction heating coils 22 and 22a are provided at substantially lower positions of the pan mounting portion 90, and a metal pan capable of induction heating is placed on the pan mounting portion 90 for cooking. it can. In this embodiment, all the three openings on the top plate 9 are pot mounting portions that can induction-heat a metal pan, but an electric heater such as a radiant heater is arranged in part below the pot mounting portion. May be. A coil base 21 in which a plurality of ferrites 24 are arranged radially is provided below the top plate 9, and an induction heating coil 22 for heating the cooking pot is provided on the coil base. The coil base 21 is fixed to the apparatus main body via a coil holding part 25. A temperature sensor 23 is attached to the central portion of the induction heating coil 22 for temperature management.

  The front left side of the main body is provided with an inlet for the grill 1 for grilling fish and the like, and the right side of the front is provided with an operation panel 60 for operating the cooking pan and heating the grill 1 and adjusting the heating power. Is displayed on the display unit 65.

  Further, a substrate case 5 on which an electronic component or the like for supplying high frequency current to the induction heating coil 22 or a fan device 4 for cooling the electronic component 52 or the like of the substrate 51 is mounted is provided on an operation panel 60. It is arrange | positioned at the side surface of the grill warehouse 1 used as back. That is, the fan device 4 is provided behind the main body with respect to the substrate disposed inside the substrate case 5. Here, the operation panel 60 is disposed on the right side of the front surface of the IH cooking heater body, and includes operation buttons 60a for selecting cooking and the like.

  That is, the grill box 1 and the substrate 51 are arranged on the left and right sides of the induction heating coil under the top plate. Here, it goes without saying that the grill cabinet 1 can be applied to the present invention at any position on the left or right side or in the center, and can be applied regardless of the arrangement of the substrates.

  In the present embodiment, the substrate 51 has a configuration in which three layers are stacked in the height direction of the substrate case 5, but the present invention does not depend on the arrangement configuration of the substrate 51. Further, it goes without saying that the present invention can be applied to a configuration in which the substrate 51 and the fan device 4 are not housed in the substrate case 5 and a resin case is provided for each substrate, for example, and these are laminated.

  As shown in the drawing, among the electronic components arranged on the substrate 51, the high heat generating component 59 can be fixed to the heat sink 55 to lower the component temperature. Here, examples of the high heat generating component 59 include an IGBT, an inverter, and a diode bridge.

  In the present invention, a circuit board for supplying a high-frequency current to the lower heating coil 13 for induction heating the heating plate 12 of the grill cabinet 1 is provided in the substrate case 5. Here, the power supply circuit of the lower heating coil 13 may be provided separately together with the induction heating coils 22 and 22a, or may be shared with the induction heating coil 22a that heats the pan mounting portion 90 on the back side, for example. That is, if the inverter power supply of the induction heating coil is shared, an increase in the volume of the board mounted on the IH cooking heater and an increase in mounting density can be suppressed, and a wide air path for cooling the coil and the board can be easily provided. Therefore, it becomes easy to cool the heating coil and the substrate that are the heat source of the grill cabinet 1, and stable induction heating can be performed in each heat source.

  In this structure, the air sucked from the intake portion 5 a of the substrate case 5 communicating with the intake port 9 a is blown out from the fan device 4 toward the substrate 51. The blown air cools the substrate 51 (the electronic component 52 and the high heat-generating component 59) that generates heat, and after the substrate 51 is cooled, it is provided above the substrate case 5, that is, below the left and right induction heating coils 22. Enter the ventilation duct 7. The air that has entered the ventilation duct 7 constitutes a flow from the outlets 7 a and 7 b toward the lower surfaces of the left and right induction heating coils 22, and a part of the air is guided to the grill cabinet 1 to cool the lower heating coil 13. Used.

  The air that has cooled these components flows through the space where the induction heating coils 22 and 22a below the top plate 9 are disposed toward the back of the main body, and is exhausted from the exhaust port 9b.

  The present invention relates to a structure for heating an object 99 to be cooked in the grill cabinet 1. The presence or absence of the substrate case 5, the arrangement of the substrate 51 and the high heating element 59 in the substrate case, the type and arrangement of the fan device 4, etc. It can be applied regardless.

  With the above configuration, with respect to the operation of the built-in type IH cooking heater according to the first embodiment shown in FIGS. 1 to 3, an example in which the cooking object 99 placed on the grill 15 of the grill cabinet 1 is heated is shown as an example. Explained.

  First, after the door 19 is opened and the object 99 is put in the grill cabinet 1, the cooking temperature and time are set on the operation panel 60, or a preset automatic cooking menu is set, and the operation button 60a is pressed to open the grill. Cooking is started. As cooking starts, the upper heater 11 or the lower heating coil 13 is energized, and the cooking object 99 is radiantly heated by the upper heater 11 and the heating plate 12 whose surface becomes hot. A heat insulating material 52a is interposed between the upper heater 11 and the ventilation duct 7, and the heat of the upper heater 11 is shielded from heat so as not to be affected by the ventilation duct 7 side.

  During cooking, fats and oils, moisture, debris, oil smoke and steam generated from the object 99 are generated. Oil and fat, moisture and debris during cooking fall to a tray 14 provided below the grill net, and oily smoke and steam are discharged to the outside through the exhaust duct 10 through the exhaust duct 10.

  Here, the saucer 14 may be filled with water before cooking. However, in this embodiment, the outside air that flows in through the gap between the doors 19 flows into the gap between the table 18 and the saucer 14, so that the saucer 14 becomes hot. Therefore, it is possible to prevent smoke and ignition from oil from the object to be cooked 99 without filling the tray 14 with water.

  That is, after the cooking of the cooking object 99 is finished, the entire inside of the chamber is scattered with fats and oils, moisture, debris, etc., and dirt and odors are attached. These require a regular cleaning in order to spoil the aroma of the cooked food when using a completely different cooking menu.

  In the structure of the present invention, the tray 14, the grille 15, and the heating plate 12 can be removed and washed from the grill cabinet 1 together with the door 19. In addition, the inside of the cabinet from which these are removed has a wide space that can reach the back side of the inside of the cabinet, and the concave and convex portions are reduced, so that wiping can be easily performed.

  Moreover, after cleaning, the heating plate 12, the receiving tray 14, and the grill net 15 can be easily returned to the original state by being inserted. The installation detection means 31 shown in the present embodiment can provide a safe and highly clean IH cooking heater without energizing the grill box even if the heating plate 12 is forgotten.

FIG. 4 is a side sectional view of the grill cabinet provided with the second embodiment.
Here, this embodiment is not directly related to the present invention, and the arrangement and configuration of the induction heating coils 22 and 22a below the top plate 9 and the substrate case 5 are the same as those of the first embodiment shown in FIG. The description is omitted.

  In FIG. 4, in this embodiment, an exhaust fan 2 that cools the saucer is provided on the back side of the grill cabinet 1 along with exhaust such as oil smoke and steam in the cabinet. The exhaust fan 2 is rotated by a fan motor 2a. It should be noted that a fan for exhausting oil smoke or steam in the cabinet and a fan for cooling the receiving tray 14 may be provided separately. However, in this embodiment, both of the fans are designed so that the storage capacity of the fan is reduced. An exhaust fan 2 having a function is arranged.

  In addition, an intake hole 1b is provided in the wall surface of the grill cabinet 1 of the present embodiment, and air is sucked into the cabinet from the intake hole 1b by the drive of the exhaust fan 2, and the air is received by the tray 14 and the table 18. Flows into the gap. Further, the air is sucked in through an exhaust air passage 3 provided on the rear rear side of the grill cabinet. In this configuration, the tray 14 can be concentrated and cooled by the air sucked from the gap between the intake hole 1b and the door 19, so that the temperature of the tray 14 can be easily lowered in addition to the first embodiment. Yes. Therefore, it is difficult for ignition or the like to occur due to the oil or fat that has fallen on the tray 14, and the safety is improved along with the cleanability of the interior.

  Further, in this embodiment, the catalyst 40 is provided in the duct 41 for exhausting oil smoke or steam in the warehouse. For example, the catalyst 40 is composed of a thermal catalyst such as a palladium catalyst or a platinum catalyst, thereby efficiently. Smoke and deodorization treatment can be performed.

  That is, in this embodiment, the flow through the catalyst 40 that is disposed behind the upper surface of the grill cabinet 1 and efficiently performs the smoke removal and deodorization treatment, and the exhaust air passage 3 that is disposed on the rear side of the grill cabinet 1 and cools the receiving tray 14. The flow through is mixed into the exhaust duct 10 and discharged, and exhausted from an exhaust port 9b provided behind the top plate 9. Here, of course, water may be put in the tray 14 in advance in order to suppress an increase in the temperature of the tray. However, the cooling fan also flows between the tray 14 and the table 18 by the exhaust fan 2 so that the temperature of the tray 14 is increased. The rise can be suppressed.

FIG. 5 is a perspective sectional view of a grill cabinet provided with a third embodiment of the present invention.
FIG. 6 is a side cross-sectional view of the IH cooking heater mounted on the grill cabinet on the grill cabinet side.
Here, since the present embodiment is not directly related to the present invention, the arrangement and configuration of the induction heating coil 22 and the substrate case 5 of the IH cooking heater on which the grill box of the present invention is mounted are the same as those of the first embodiment. Description is omitted.

  5 and 6, the present embodiment has a configuration in which the upper heating coil 11a is provided on the upper side of the grill cabinet 1, and the lower heating coil 13 is provided on the lower side. Therefore, similarly to the lower heating coil 13 on the lower side, the upper heating coil 11a is arranged via the table 18, and the heating plate 12 is arranged so as to be close to the upper heating coil 11a with the table 18 in between. A storage shelf 1a is provided.

  Therefore, in the structure of the present embodiment, the unevenness of the upper, lower, left and right wall surfaces in the chamber is small, and after cooking of the cooking object 99 is completed, the saucer 14, the grill 15 and the two heating plates 12 are pulled out together with the door 19. Thus, it is possible to wipe the inside of the refrigerator with a hand.

  In addition, the heating method and usage of the to-be-cooked object 99 placed on the grill 15 on the saucer 14 are the same as those in the first embodiment, and the cooling structure of the saucer 14 is also the configuration of the above-described example. An IH cooking heater having both safety and cleanability can be provided.

  Moreover, the cooling of the upper heating coil 11a can be easily performed using the ventilation duct 7 of the induction heating coil 22 located above the upper heating coil 11a.

Here, as in the case of the present embodiment, the arrangement and configuration of the heating coil 22 and the substrate case 5 below the top plate 9 that are not directly related to the present invention are the same as those in FIG.

  In FIG. 7, in the present embodiment, a receiving tray 14 a that is housed in the cabinet in conjunction with the door 19 is provided on the lower outside of the grill cabinet 1. That is, the tray 14a provided below the grill cabinet 1 slides back and forth in conjunction with the door 19, so that when the door is pulled out, the oil, moisture, and debris of the cooking object 99 are placed on the kitchen floor. Prevents falling. Further, since the tray 14a is not in the cabinet, the distance between the heating plate 12 and the lower heating coil 13 can be reduced, and the heating plate 12 is easily induction-heated.

  In this embodiment, the oil and moisture coming out of the object to be cooked fall and accumulate on the table 18, so that in consideration of safety such as ignition, the heating of the heating plate 12 by the lower heating coil 13 compared to the above embodiment. Can not be strengthened.

  However, it can be cooked sufficiently by extending the heating time, and there is no problem at all when performing oven heating with the internal temperature kept at a high temperature. Furthermore, the cleanability inside the cabinet, which is a problem to be solved by the present invention, is as high as in the above embodiment.

FIG. 8 is a perspective view of a grill cabinet provided with a fifth embodiment of the present invention.
FIG. 9 is a side sectional view on the grill cabinet side provided with the fifth embodiment of the present invention.
8 and 9, in this embodiment, the door 19 is configured to open and close with the lower side as an axis by the rotation of the door arm 19a. Therefore, like the heating plate 12, the grill 15 is also placed on the storage shelf in the cabinet. Further, since the grill 15 is housed in the gap between the upper and lower heating plates 12, the cooking object 99 on the grill 15 is heated by the radiant heat of the upper and lower heating plates 12. Therefore, in this embodiment, the cooking object 99 can be cooked as in the fourth embodiment.

  Further, in the case of the grill cabinet of this configuration, the structure can be simplified without providing a tray, and if there is no tray, the distance between the lower heating coil 13 and the heating table 12 can be easily reduced, and the heating efficiency of the heating plate 12 is increased. You can also

  As described above, according to the present invention, it is possible to configure the interior shape with less unevenness by eliminating protrusions such as conventional electric heaters that are fixedly exposed in the interior. Moreover, since the heating plate which becomes high temperature can be taken out easily, cleanability improves.

  Further, even in the case of an IH cooking heater having a height restriction in the grill cabinet, the protrusion due to the exposure of the heater inside the cabinet is eliminated, so that the hand can easily reach the back of the cabinet and can be wiped to every corner.

  In addition to improving the ease of handling and storage of the heating plate, the storage shelf provided in the cabinet according to the width of the heating plate can easily keep the distance between the heating coil and the heating plate constant, so that efficient and stable induction is possible. Heat generation can be controlled by heating.

  Moreover, the storage shelf which puts a heating plate can be comprised by the unevenness | corrugation of the wall surface in a warehouse, and the heating plate which can be taken out easily can be installed, without impairing the cleaning property in a warehouse.

  In addition, it is easy to provide a wide air path for cooling the coil and the substrate by suppressing the increase in the volume of the substrate mounted on the IH cooking heater and the increase in the mounting density by sharing the inverter power supply. Therefore, it becomes easy to cool the heating coil and the substrate that are the heat source of the grill cabinet, and stable induction heating can be performed in each heat source.

  Moreover, abnormal overheating of the heating plate can be detected, the temperature inside the grill can be controlled safely, and the heating and cooking of the cooking object can be adjusted.

  Furthermore, it is possible to suppress energization to the heating coil of the grill cabinet in a state where the heating plate is taken out, safely attach and detach the heating plate, and provide an IH cooking heater with high cleanability.
