Description

  The present invention relates to a system kitchen, and more particularly to a system kitchen suitable for placing an cooking container on a top board and performing induction heating cooking via a coil unit.

  As shown in FIG. 9, the system kitchen 50 installed in the kitchen includes a sink cabinet 51, a stove cabinet 52 installed adjacent to the sink cabinet 51, and a single top plate 53 that covers them. ing. In the system kitchen 50, a sink 54 is formed in a sink area A that covers the sink cabinet 51 of the top plate 53, and hot water is supplied from the faucet 61 to the sink 54. A rectangular opening 56 is cut out near the front portion of the stove area B that covers the stove cabinet 52, and one stove 55 is dropped onto the stove cabinet 52 from the opening 56. In addition, a cooking table unit region C is formed between the sink region A and the stove region B, and the user cooks food on the top plate 53 pasted on the upper surface of the cooking table unit region C. Or put utensils or tableware necessary for cooking.

  Here, the system kitchen is generally a modular and coordinated combination with various floor cabinets for storage, a work top on the floor cabinet, and a sink or cooking device as necessary. It is a type kitchen, and in a broad sense includes a partition storage cabinet and a dining counter. These worktops or counters are collectively referred to below as the top board.

  FIG. 10 shows an example of use in the stove area B and the counter unit area C.

  In the example shown in FIG. 10, first, in the stove area B, the main body case 81 constituting the main body of the stove 55 is fixedly mounted in a lowered state from the top plate. A plurality of gas burners 84 are disposed in the main body of the stove 55, and a cover 83 provided on the upper surface is provided with a burner opening 85 through which each gas burner 84 faces. Furthermore, a virtues 86 are disposed above the burner opening 85, and the virtues 86 along the bottom surface of the cooking pan 74 or the like in which the flame of the burner or the hot air generated by the flames is placed on the claws of the virtues 86 is provided. It is designed to be released to the outside. That is, by burning the gas burner 84, it becomes possible to heat-cook the food in the cooking pan 74 placed on the virtues 86.

  In the cooking table unit area C, a cutting board 91 for actually chopping and processing food, a stainless steel tableware bowl 92 for drying washed dishes, and the like are placed. Furthermore, cooking equipment and the like necessary for actual cooking such as the toaster 65, the juicer 69, the rice cooker 71, and the like are arranged narrowly. These cooking appliances are supplied with power via an outlet 61 and a plug 67.

  As an alternative to various cooking devices such as the toaster 65, juicer 69, rice cooker 71 and the like, various cooking devices such as a whisk and a dishwasher may be arranged in the cooking table unit region C. Will be supplied.

  By the way, while a lot of recipes are being studied, the necessity of operating many cooking devices at the same time is increasing in recent years when a wide variety of cooking, which is a variety of Japanese, Western, and Eastern and Western, has become feasible at home.

  However, in order to simultaneously operate many cooking appliances in the conventional system kitchen as described above, many cooking appliances must be arranged in the cooking unit unit area C having a limited area. For this reason, the space for placing other tableware including the tableware bowl 92 and the space for processing food using the cutting board 91 are inevitably reduced. In addition, in the stove area B adjacent to the cooking stove unit area C, food or the like put in the cooking pan may be boiled at the same time using the gas stove, but the heat from the gas stove on the cooking stove unit area C Since heat may be transferred to the cooking equipment that is placed, further restrictions are imposed on the location of the cooking equipment.

  On the other hand, when cooking many foods at the same time using many gas stoves, it is necessary to increase the number of gas stoves. There is a case where it is desired to set the occupation rate of the unit area C low. Further, in the existing system kitchen shown in FIG. 10, the main body case is fixedly mounted in a state of being dropped from the top plate, and it has not been possible to add a gas stove and move the gas stove area significantly.

  Therefore, it is desired to realize such cooking more efficiently by changing the occupation ratio of the cooking table unit area C and the stove area B on the top plate according to the user's intention.

  In particular, in order to meet such demands, the most important issue is how to improve the degree of freedom of arrangement of the gas stove. In order to solve such a problem, a method of using an induction heating device that performs cooking using electromagnetic induction as an alternative to the gas stove has been proposed (see, for example, Patent Document 1).

  As shown in FIG. 11, for example, the induction heating device 100 disclosed in Patent Document 1 includes a load unit 98 represented by a cooking pan and the like, and a magnetic generation unit 99 that induction heats the load unit 98. The generating unit 99 is provided with a top plate 103 for placing the load unit 98, a primary coil 104 that is provided below the top plate 103 and generates a high-frequency magnetic field for performing the induction heating, and the primary coil 104. And the inverter 107 is supplied with power via a power cord 109.

Since the user can arrange the magnetism generating unit 99 at an arbitrary position on the top board, the induction heating device 100 and the cooking device can be separated without distinguishing the cooking table unit region C and the stove region B. It is possible to enjoy variations in the arrangement between them.
JP-A-5-184471 JP 2006-230516 A

  However, when this conventional induction heating device 100 is used as an alternative to the above-described gas stove, not only the load portion 98 but also the magnetic generator 99 main body must be placed on the top plate. The magnetism generator 99 is wide in width and depth because of mounting various devices such as the primary coil 104 and the inverter 107, and the thickness is increased. For this reason, the magnetism generating unit 99 itself placed on the top plate will also occupy a vast space, and the degree of freedom of arrangement in other cooking equipment cannot be secured, and consequently on the top plate. There arises a problem that the space cannot be used effectively.

  Moreover, in this induction heating apparatus 100, since the power cord 109 connected to the inverter 107 is placed on the top plate, the troublesomeness cannot be eliminated. In particular, when many cooking devices are used at the same time, the power cord 109 must be connected by a so-called octopus leg wiring using the plug 67 in addition to the outlet 61, and the current that can flow is limited and the limitation is imposed. If an excess current is passed, the power cord itself may heat up and cause a fire. In addition, the arrangement position of the induction heating device 100 on the top plate is governed solely by the length of the power cord 109, the position of the outlet provided in the system kitchen, and the like, and there are certain restrictions on the degree of freedom of such arrangement. It will take.

  For this reason, for example, in Patent Document 2, a space corresponding to at least a position where the cooking container can be placed is formed in the lower part of the top plate on which the cooking container is placed, and the coil unit can be freely moved in this space And a technique for identifying the placement position of the cooking container on the top plate and moving the coil unit to the identified placement position of the cooking container.

  Thereby, even when the cooking container is placed at an arbitrary position on the top plate, the placement position can be automatically identified, and the coil unit can be moved to the placement position. Furthermore, the cooking container can be induction heated by the high frequency magnetic field generated by the coil unit. In other words, the user only has to place the cooking container on a desired location on the top board, and the system kitchen automatically performs all the adjustment of the positions of the remaining coil units. Even when the variation is slightly modified, the burden of labor can be reduced.

  However, in the technique disclosed in Patent Document 2 described above, in addition to the induction heating device, a device for moving the device must be disposed in the lower portion of the top plate, and the heat generated from these devices is generated by the top plate. Accumulate at the bottom. Since this accumulated heat may adversely affect the induction heating device and its movable device, it is necessary to perform a cold heat treatment.

  Therefore, the present invention has been devised in view of the above-described problems, and the object of the present invention is to arrange a cooking container to be induction-heated at an arbitrary position on the top plate according to the user's request. It is another object of the present invention to provide a system kitchen that can be used, can effectively use the space on the top plate, and can effectively perform the heat treatment of the lower portion of the top plate.

  In order to solve the above-described problems, a system kitchen to which the present invention is applied has at least a top plate that can be used as a cooking area, an induction heating coil for generating a high-frequency magnetic field, and an inverter circuit that drives the induction heating coil. And a flat base plate on which a coil unit capable of inductively heating the cooking container by a magnetic field from the induction heating coil is mounted, horizontal moving means for moving the base plate in one horizontal direction, and the top plate Cooling means for cooling by blowing along a longitudinal direction corresponding to the moving direction of the base plate in the space, and a space formed in accordance with a region where the base plate can move at least by the horizontal moving means in the lower part It is characterized by providing.

  In order to solve the above-described problems, a system kitchen to which the present invention is applied has at least a top plate that can be used as a cooking area, an induction heating coil for generating a high-frequency magnetic field, and an inverter circuit that drives the induction heating coil.

To do.

  As a result, by blowing air along the longitudinal direction into the elongated space, the air can be passed in a substantially straight line, and the air can circulate or stagnate partially. The cooling efficiency can be improved because it is eliminated. In addition, since the space can be configured with a small volume, a large cooling effect can be obtained with a small amount of power.

The control block 332 is configured by further connecting a cooling fan 354, an alarm 362, a display unit 363, and an operation unit 357 to the control circuit 347.

  As shown in FIG. 5, each of the above-described components is mounted inside the housing 305. In particular, the inverter block 331 and the control block 332 are mounted on the mounting table 306. The housing 305 has an intake port 358 formed on the bottom surface near the position where the cooling fan 354 is disposed, and an exhaust port 359 formed on one side surface.

  Next, each component of the inverter block 331 will be described in detail. The rectifier circuit 333 is arranged to rectify the power supply current from the connected power plug 329, and converts the supplied power supply current as alternating current into direct current. The LC series circuit constituted by the choke coil 334 and the capacitor 335 constitutes a so-called smoothing circuit. The switching elements 336 and 337 are configured by transistors, for example, and reverse conduction diodes 362 and 363 are connected in parallel to the emitters and collectors of the switching elements 336 and 337, respectively. The drive signal QA from the inverter drive circuit 348 is supplied to the base of the switching element 336, and the drive signal QB from the inverter drive circuit 348 is supplied to the base of the switching element 337. That is, the inverter drive circuit 348 can supply a resonance current to the resonance capacitors 338 and 339 and the induction heating coil 342 by alternately supplying the drive signal QA and the drive signal QB.

  As shown in FIG. 5, the induction heating coil 342 is disposed to face the upper surface 305 a of the housing 305. The number of turns in the induction heating coil 342 governs the electric power when the cooking container 20 is heated, and is optimally adjusted in relation to the skin resistance of the bottom plate and the magnitude of the resonance current in the cooking container 20. Need to be. The induction heating coil 342 is resonated based on the supplied resonance current, and as a result, a high frequency magnetic field can be generated.

  The circuit protection thermo 341 is composed of a thermistor or the like whose resistance value changes according to a change in temperature, and mainly measures the temperature of the space that constitutes the inverter block 331 and the control block 332.

  The temperature detection thermistor 350 is formed of a thermistor as with the circuit protection thermo 341. The pan temperature detection thermistor 350 is for detecting the temperature of the cooking container 20 via the top plate 13 and is disposed near the center of the induction heating coil 342 as described above. Furthermore, the current transformer 340 is a coil or the like for detecting the current value of the resonance current flowing through the induction heating coil.

  Next, each component of the control block 332 will be described in detail. The primary current detection circuit 345 detects the current value of the power supply current supplied via the power plug 329 via the connected current detection coil 344. Then, the primary current detection circuit 345 notifies the control circuit 347 of the detected current value.

  The power supply voltage detection circuit 346 detects a voltage based on the power supply current from the power supply plug 329 and notifies the control circuit 347 of the detected voltage.

  The control circuit 347 is provided in a central control unit 358 configured with, for example, a CPU. When the current value detected by the primary detection circuit 345 described above is notified to the control circuit 347 and the voltage detected by the power supply voltage detection circuit 346 is notified, the control circuit 347 is set with reference to these. The inverter drive circuit 348 is controlled so as to obtain the necessary power. In addition, the control circuit 347 interprets a command from the user via the operation unit 357, controls the inverter drive circuit 348, the cooling fan 354, and the alarm 362 based on the command, and also displays predetermined information via the display unit 363.

  The temperature detection circuit 349 detects a change in resistance value in the circuit protection thermo 341. The temperature detection circuit 349 detects the temperature inside the housing 305 based on the detected change in the resistance value of the circuit protection thermo 341. The temperature detection circuit 349 notifies the control circuit 347 of the detected temperature inside the housing 305. The control circuit 347 can recognize the temperature inside the housing 305 at any time through the notification from the temperature detection circuit 349. Thereby, for example, when the cooling fan or the like is stopped during operation, or when the cooling performance is deteriorated, such as when the intake port 358 or the exhaust port 359 is clogged, and the temperature inside the housing 305 rapidly increases. In addition, the control circuit 347 can recognize this via the temperature detection circuit 349 and can stop the operation of the IH heater coils 3a to 3d.

  The coil current detection circuit 351 reads the current value of the resonance current detected by the current transformer 340 and notifies the control circuit 347 of this value. The control circuit 347 can recognize the current value of the resonance current at any time via the coil current detection circuit 351. Thereby, the control circuit 347 can suppress, for example, the flow of resonance current more than necessary for the power necessary for induction heating determined according to the material and shape of the cooking container 20, Furthermore, when the cooking container 20 is removed during induction heating, the operation of the IH heater coils 3a to 3d can be stopped and the user can be notified via the alarm 362.

  The pan temperature detection circuit 352 detects a change in the resistance value in the pan temperature detection thermistor 350 and detects the temperature of the cooking container 20 based on the detected change in the resistance value of the pan temperature detection thermistor 350. Then, the pan temperature detection circuit 352 notifies the control circuit 347 of the detected temperature of the cooking container 20. Thereby, the control circuit 347 can recognize the temperature of the cooking container 20 at any time via the notification from the temperature detection circuit 349. For example, when the temperature of the bottom of the cooking container 20 rises above a specified value. It is also possible to stop the operation of the IH heater coils 3a to 3d.

  The cooling fan 354 rotates based on the control by the control circuit 347, and the cooling air is sucked from the intake port 358 according to the rotation of the cooling fan 354. Then, the sucked cooling air passes through the inverter block 331 and the control block 332 to cool them, and is discharged from the discharge port 359 to the outside.

  The alarm 362 is composed of an audio oscillator that generates a predetermined sound based on control by the control circuit 347.

  The operation unit 357 is provided with keys and buttons for the user to actually operate the IH heater coils 3a to 3d. The content input from the user in the operation unit 357 is notified to the control unit 401, and the control unit 401 notifies the connected control circuit 347 of this, and the control circuit 347 performs IH based on the input content. Each component of the heater coils 3a to 3d is controlled. The operation unit 357 is assumed to be a liquid crystal touch panel or the like. However, the operation unit 357 is not limited to this. For example, the operation unit 357 includes a remote controller for transmitting input content from a user through wireless communication. Also good.

  Next, an operation of the IH heater coils 3a to 3d, that is, a method of induction heating the cooking container 20 by the IH heater coils 3a to 3d configured as described above will be described.

  First, a cooking container 20 such as a pan is placed at an arbitrary position on the top plate 13, and the IH heater coil is moved to a region directly below the cooking container 20. Specifically, when the user operates the operation unit 357, the information is transmitted to the central control unit 358, and the corresponding motor 260 is driven according to the instruction of the central control unit 358, and all of the IH heater coils 3a to 3d, Alternatively, the IH heater coil closest to the cooking container 20 in the horizontal direction X moves in the vertical direction Y.

  Next, the cooking container 20 is dielectrically heated by an IH heater coil disposed immediately below the cooking container 20. Specifically, first, the power supply current is received from the power plug 329 through the power cord 330. The received power supply current is rectified in the rectifier circuit 333. At this time, the inverter drive circuit 348 adjusts the drive signals QA and QB supplied to the switching elements 336 and 337 under the control of the control circuit 347.

FIG. 6A is a diagram illustrating a resonance current flowing through the induction heating coil 342, FIG. 6B is a diagram illustrating a drive signal QA supplied to the switching element 336, and FIG. 6 is a diagram illustrating a drive signal QB supplied to a switching element 337. FIG. As shown in FIG. 6 (a) ~ (c) , inverter driver circuit 348, under control of the control circuit 347, ON driving signal QA drive time from time _{t 0} until the time point _{t 1} is T1 output To do. During the driving time T1, resonance occurs in a closed circuit formed by the switching element 336, the diode 362, the induction heating coil 342, and the resonance capacitor 338. The inverter drive circuit 348 turns OFF the drive signal QA when a time _{t 1.}

Then, inverter driver circuit 348, under control of the control circuit 347, the time driving from the time _{t 2} is ON outputs a drive signal QB is T2. During the driving time T2, resonance occurs in a closed circuit formed by the switching element 337, the diode 363, the induction heating coil 342, and the resonance capacitor 339. The driving time T2 is the same as the driving time T1.

  Thus, by changing the closed circuit to resonate the induction heating coil 342, a high frequency magnetic field can be generated in the induction heating coil 342. The generated high-frequency magnetic field passes through the bottom plate of the cooking container 20 through the top plate 13. Since the bottom plate of the cooking container 20 is made of metal, an eddy current is generated by passing the high-frequency magnetic field through the metal bottom plate. Due to this eddy current and the electrical resistance of the cooking container 20, Joule heat is generated, and the cooking container 20 itself generates heat. As a result, the food in the cooking container 20 can be heated and cooked.

  In the system kitchen 1 of the present embodiment, a plurality of IH heater coils are arranged in the horizontal direction X of the cooking counter area D, and these IH heater coils can be moved in the vertical direction Y of the cooking counter area D. Therefore, by moving the IH heater coil, the user can place the heating cooking container 20 at an arbitrary position on the top board 13, and can cook by heating at a convenient place depending on the cooking contents. . Moreover, since the area | region which is not heat-cooking can be used as a cooking table, the position of a cooking table space is not limited, Compared with the conventional system kitchen, a cooking table space can be taken widely. Furthermore, in this system kitchen 1, since almost all the areas in the heating cooking area D are dielectric heating areas and cooking area, the width of the cooking area and the heating space are changed flexibly as appropriate. Thus, the limited space on the top plate 13 can be used efficiently.

  Thus, for example, the dielectric heating unit (IH heater coil 3d) is arranged in the vicinity of the sink 14 and the user by moving the IH heater coil 3d arranged closest to the sink 14 to the area in front of the user. Therefore, the cooking container 20 filled with water and heavy in the sink area A can be easily placed in the dielectric heating area (the area directly above the IH heater coil 3d). As a result, it is no longer necessary to carry over the cooking table area to the induction heating area as in the prior art, reducing the burden on the user's labor and improving the work efficiency.

  Moreover, the system kitchen 1 of this embodiment may detect the position of the cooking container 20 by the sensor 261, and the IH heater coil may automatically stop immediately below the position, and the user can position the IH heater coil. There is no need to adjust. Further, when the configuration of the sensor 261 is omitted, it may be controlled by manual control via the operation unit 357.

  Furthermore, in the system kitchen 1 of this embodiment, since the top plate 13 also serves as a mounting surface of the cooking container 20 in the IH heater coil, there is no step on the work top surface (top plate 13), and cooking work is performed. It can be performed smoothly and the cleaning property can be improved.

  Furthermore, in this system kitchen 1, since the operation part 357 is arrange | positioned at the both ends in the vertical direction Y of the cooking-kitchen area | region D, when several users face each other, it can operate from either. Workability is improved. Furthermore, since the position of the IH heater coil in the initial state is the central portion in the vertical direction Y, even when a plurality of users face each other, an area near the user can be ensured as a cooking space.

  In the system kitchen 1 of the present embodiment, four IH heater coils serving as heating units are disposed, but the present invention is not limited to this, and a plurality of IH heaters in the lateral direction X are provided. The coil should just be arranged and the number can be changed according to the length in the horizontal direction X of the cabinet 11. Moreover, in the system kitchen 1 of this embodiment, it is good also as a structure which arranges a some IH heater coil in a Y direction.

  Furthermore, although the present embodiment has been described with an island type system kitchen as an example, the present invention is not limited to this, and the configuration of the present invention includes a work table provided with a sink area A and cooking. A so-called one-row kitchen in which work tables provided with the part D are arranged in a line, and a work table provided with the sink area A and a work table provided with the heating cooking part D are arranged in an L shape. It can also be applied to so-called L-shaped kitchens. Furthermore, the position of the initial state of the IH heater coil is not limited to the central portion in the vertical direction Y, and can be set as appropriate according to the application. For example, when applied to a single-row kitchen, The state where the IH heater coil is moved to the wall surface side can be set as the initial state.

  In the present invention, an air cooling system for air cooling the area heated by the IH heater coil 3 is mounted below the top plate 13.

  As described above, the region where the IH heater coil 3 can move is an elongated region along the moving direction. The movable region of the IH heater coil 3 is surrounded by side plates 120a to 120d as shown in FIGS. As a result, an elongated space 121 is formed for each of the IH heater coils 3a to 3d surrounded by the side plates 120a to 120d and further surrounded by the bottom surface 23 and the top plate 13 according to the movable region of the IH heater coil 3. It will be. Incidentally, this space 121 is not limited to being a closed space, but may be configured as an open space by forming a gap in the side plate 120d that partitions the adjacent IH heater coils 3a to 3d. Good. In the following description, the moving direction y of the IH heater coil 3 is a longitudinal direction y in the space 121.

  In the space 121, the one side plate 120a is provided with a blower 122 that blows air toward the inside. Further, an exhaust port 123 is provided in the side plate 120c facing the side plate 120a. That is, in the spaces 121a to 121d corresponding to the IH heater coil 3a, the fans 122a to 122d and the exhaust ports 123a to 123d are provided independently of each other.

  When the blower 122 is operated, air from the outside is taken into the space 121. The air blown into the space 121 travels straight along the moving direction y of the IH heater coil 3, that is, the longitudinal direction y in the space 121, or reflects the side walls 120 b and d through the exhaust port 123. Will be discharged to the outside. As a result, the heat accumulated in the space 121 can be discharged to the outside by blowing air, and the air in the space 121 can be cooled.

  In particular, by providing the blower 122 and the exhaust port 123 so as to face each other, the cooling gas taken into the interior goes straight as it is and is discharged to the outside through the exhaust port 123. Efficiency can be improved.

  The space 121 is provided for each of the IH heater coils 3a to 3d. Accordingly, the volume of each space 121 separated by the side wall 120 can be reduced. Further, the space 121 can be elongated in the longitudinal direction y corresponding to the moving direction of the IH heater coil 3.

  By blowing air along the longitudinal direction y into the space 121 having such an elongated shape, the air can be passed in a substantially straight line, and the air is partially circulated or stagnated. Therefore, the cooling efficiency can be improved. Moreover, since the space 121 can be configured with a small volume, a large cooling effect can be obtained with a small amount of power.

  Furthermore, the fans 122a to 122d provided for the spaces 121a to 121d can be controlled independently of each other. For this reason, if cooking is performed using only the IH heater coil 3b, it is sufficient to operate only the blower 122b and cool only the space 121b. Good. For this reason, since it becomes unnecessary to operate all the air blowers 122 in one air blowing cooling operation, it contributes also to power saving.

  Incidentally, the fans 122a to 122d are controlled by the central control unit 358. When the central control unit 358 performs the ON / OFF operation on the fans 122a to 122d, it may be based on the ON / OFF operation by the user, or after the heating operation by the IH heater coil 3 is finished, The control unit 358 may identify this and perform an ON / OFF operation automatically. Thereby, the effort which controls the air blower 122 by a user's manual operation can be reduced. At this time, the central control unit 358 identifies which heating operation of the IH heater coils 3a to 3d has been completed, and then to any one or more of the fans 122a to 122d at the location where the heating operation has actually ended. The cooling operation may be performed by focusing only on the above.

  FIG. 8 shows another embodiment of the air cooling system. In this air cooling system, a cooling medium is brought into contact with the back surface of the top plate 13 and a wiping operation is performed in the longitudinal direction y. Along the moving direction y of the IH heater coil 3, the cloth body 131 is stretched between the roll bodies 133 and 134 so as to contact the back surface of the top plate 13. One end of the cloth body 131 is pulled downward via the roll body 133 and wound by the winder 135. Further, the other end of the cloth body 131 is pulled downward via the roll body 134 and wound up by the winder 136.

  The winders 135 and 136 are controlled by the central control unit 358, respectively. Actually, the central control unit 358 controls the winders 135 and 136 so as to rotate alternately at different timings. As a result, the cloth body 131 wound around the winders 135 and 136 reciprocates along the moving direction y. Since the cloth body 131 is in contact with the back surface of the top plate 13 as described above, when the cloth body 131 is reciprocated along the moving direction y in this state, the back surface of the top plate 13 is, so to speak, the cloth body 131. Thus, it is possible to obtain the same effect as that obtained by wiping. Thereby, the top plate 13 can be cooled.

  Incidentally, in order to enhance the cooling effect by moistening the cloth body 131, for example, a spraying section (not shown) is provided and sprayed through the spraying section before actually performing the cooling operation. It may be moistened. Further, gel or the like may be used as an alternative to the cloth body 131. Further, a cooling gel may be provided on a part of the cloth body 131 and the top plate 13 may be cooled by using the gel.

  When the central control unit 358 performs the ON / OFF operation on the winders 135 and 136, it may be based on the ON / OFF operation by the user, or the heating operation by the IH heater coil 3 ends. Later, the central control unit 358 may identify this and automatically perform the ON / OFF operation. At this time, the central control unit 358 identifies which heating operation of the IH heater coils 3a to 3d has been completed, and then to any one or more of the winders 135 and 136 where the heating operation has actually ended. Alternatively, the cooling operation may be performed by focusing only on it.

  In the above-described embodiment, the cooling medium is described by taking two examples of the air feeding by the blower 122 and the wiping operation by the cloth body 131 as an example. However, the present invention is not limited to this, and the H heater coil 3 is mounted. Of course, any structure may be used as long as it is cooled through the cooling medium along the longitudinal direction corresponding to the moving direction of the base plate 4.
