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. 7, 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. 8 shows an example of use in the stove area B and the cooking table unit area C.

  In the example shown in FIG. 8, first, in the stove area B, the main body case 81 constituting the main body of the stove 55 is fixedly mounted in a state of being dropped 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, as many 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. 8, 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 electromagnetic induction heating apparatus that performs cooking using electromagnetic induction as an alternative to the gas stove has been proposed (for example, see Patent Document 1).

  The electromagnetic induction heating device 100 shown in Patent Document 1 includes, for example, as shown in FIG. 9, a load portion 98 represented by a cooking pan and the like, and a magnetic generation portion 99 that induction heats the load portion 98. The magnetic generator 99 includes a top plate 103 on which the load unit 98 is placed, 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. And an inverter 107 for driving 104, and power is supplied to the inverter 107 via a power cord 109.

Since the user can arrange the magnetism generating unit 99 at an arbitrary position on the top plate, the electromagnetic induction heating device 100, the cooking appliance, and the cooking table unit area C and the stove area B are not distinguished. It becomes possible to enjoy the variation of free arrangement between.
JP-A-5-184471

  However, when this conventional electromagnetic induction heating device 100 is used as an alternative to the above-described gas stove, not only the load unit 98 but also the magnetism generating unit 99 main body must be placed on the top plate. For this reason, when it is desired to make the cooking table unit area C wider, or when it is desired to use the entire space on the top plate as the cooking table unit area C, the electromagnetic induction heating device 100 is also placed on the top plate. There was a problem that this would be an obstacle.

  Further, when it is desired to use the kitchen unit area C more widely, the electromagnetic induction heating device 100 is removed from the top plate and stored in, for example, a cabinet or the like in the system kitchen. Will increase the burden. In addition, when cooking is desired using the electromagnetic induction heating device 100 once stored, the electromagnetic induction heating device 100 has to be taken out again and moved onto the top plate.

  That is, by creating a system that easily stores and removes the electromagnetic induction heating device 100, it is necessary to be able to freely change the size of the cooking unit unit area while reducing the user's labor as much as possible. .

  Therefore, the present invention has been devised in view of the above-described problems, and an object of the present invention is to provide a system kitchen capable of easily storing and taking out the electromagnetic induction heating device. There is.

Characterized in that it is.

  The system kitchen to which the present invention is applied has a top plate, an induction heating coil for generating a high-frequency magnetic field, and an inverter circuit for driving the induction heating coil in order to solve the above-described problem. A flat base plate on which a coil unit capable of inductively heating the cooking container by a magnetic field from the above is mounted, and a storage portion that can be vertically stored so that the upper and lower surfaces of the base plate are in a substantially vertical direction below the top plate.

  Hereinafter, as the best mode for carrying out the present invention, a system kitchen applied when cooking food in a restaurant or home will be described in detail with reference to the drawings.

  A system kitchen 1 to which the present invention is applied is a system kitchen having at least a work top or a counter (hereinafter referred to as a top plate), as shown in FIGS. 1 (a) and 1 (b), A top plate 13 covering the upper surface of the cabinet 11, a sink 14 formed in a sink area A adjacent to the top plate 13, and a faucet 15 for supplying hot water to the sink 14 are provided. . In the following, the case where the system kitchen 1 is applied as a so-called island kitchen in which the kitchen work table is separated from the wall surface and is provided in an island type will be described. However, the present invention is not limited to such a case. Further, the present invention may be applied to a so-called one-row kitchen in which work tables with stove are arranged in one row, or a so-called L-type kitchen in which sinks and stoves are arranged in an L-shape.

  For example, the cabinet 11 may be provided with doors and storage drawers (not shown) that are pivotally mounted on the front side so as to be able to be opened in one side. Each of these doors and storage drawers can mainly store kitchen utensils, tableware, and the like. A simple shelf or case may be provided.

  The sink 14 is formed with a draining recess or the like, and a drain outlet is provided on the bottom surface. In the sink 14, the recess and the drain port are integrally formed with each other by a method such as press molding, cast molding, injection molding, or the like. The material of the sink 14 is not particularly limited, but a metal such as a heat-resistant resin or a stainless steel plate can also be used.

  The top plate 13 is composed of a glass plate having a smooth surface. On the top plate 13, a cooking container represented by a cooking pan or pot for cooking foods and the like, and a cutting board for actually chopping and processing the foods can be placed at any position of the user. It is made into the composition.

  There may be a plurality of cooking containers placed on the top plate 13 at arbitrary positions. In addition to the cutting board, various cooking devices 20 such as a tableware bowl, rice cooker, juicer, etc. (not shown) are provided. There is a case where it is placed at an arbitrary position. That is, the top plate 13 is a place where the cooking container 20 may be placed. Therefore, it is necessary to configure the top plate 13 with a material excellent in heat resistance, impact resistance, chemical resistance, and mechanical strength. Usually, it is made of heat-resistant glass or ceramics.

  Incidentally, in the system kitchen 1 to which the present invention is applied, the cooking container 20 placed on the top plate 13 is induction-heated using a coil unit represented by an IH (electromagnetic induction heating) heater or the like. Actually, this induction heating is executed through the arranged IH heater device 3.

  The IH heater device 3 houses a coil unit 31 as an IH heater. Usually, when this coil unit 31 is not used, it is in a state of being stored as shown in FIG. 1 (a). However, when cooking is performed through the cooking container 20, FIG. The coil unit 31 is pulled out and placed on the top plate 13 as shown in FIG. The coil unit 31 is actually mounted on a base plate 32 on a flat plate.

   FIG. 2 shows a cross-sectional configuration when the coil unit 31 is housed in one IH heater device 3.

  In the lower part of the top plate 13, the storage part 33 that can be stored vertically is vertical so that the upper surfaces 32a and 32b of the base plate 32 are in a substantially vertical direction (so that the normal vector direction of the upper surface 32a and the upper surface 32b is in a substantially horizontal direction). It is formed facing downward.

  Around the storage unit 33, an operation button 21, a rotation drive unit 35, a power supply circuit unit 36, and a lift control unit 38 are provided. One end 34 a of an arm 34 is attached to the rotation drive unit 35.

  The operation button 21 is used by the user to instruct the automatic withdrawal and storage of the base plate 32. If the operation button 21 is pressed by the user, an operation signal to that effect is generated and sent to the rotation drive unit 35 and the elevation control unit 38.

  The arm 34 is configured to be rotatable in the w direction in the drawing based on the control by the rotation driving unit 35 attached to the one end 34a. The arm 34 is configured to be bent at a bending point 34b and further extended upward, and a support mechanism for supporting the base plate 32 is provided at the end 34c. This support mechanism includes an engaging portion for locking the lower end of the base plate 32. That is, the lower end of the base plate 32 is locked by the support mechanism in the arm 34, so that the base plate 32 can be held in an upright state in the vertical direction.

  The arm 34 is provided with a rotation shaft 49. The rotating shaft 49 is freely engageable with a rotating shaft engaging groove 35 a in the rotation driving unit 35. The rotary shaft 49 is connected to various types of rotary dampers (not shown) that use the viscous resistance of liquid or frictional resistance. As a result, the pivoting operation of the arm 34 can be delayed, and the impact on the top plate 13 of the base plate 32 supported by the arm 34 can be absorbed.

  The rotation driving unit 35 may be equipped with a control unit using a CPU (not shown), and may automatically rotate the arm 34 in response to an operation signal sent from the operation button 21.

  The power supply circuit unit 36 supplies power for performing the storing operation and the drawing operation of the base plate 32 and power for the induction heating operation by the coil unit 31.

  The lift control unit 38 operates based on control by a CPU or the like (not shown), receives the operation signal sent from the operation button 21, pulls up the base plate 32 in the vertical direction, or directs the base plate 32 in the vertical direction. Execute the lifting / lowering operation. This raising / lowering operation may be executed via an actuator (not shown).

  Next, the configuration of the coil unit 31 will be described. FIG. 3 is a block configuration diagram of these coil units 31, and FIG. 4 is a configuration cross-sectional view of the coil units 31. As shown in FIGS. 3 and 4, the coil unit 31 is roughly divided into an inverter block 331 and a control block 332. The inverter block 331 is a block for controlling a high-frequency magnetic field that is actually induction-heated, and the control block 332 is a block for controlling the entire coil unit 3.

  The inverter block 331 is disposed between the power cord 330 and the rectifier circuit 333, and a rectifier circuit 333 that receives household AC200V (50/60 Hz) power from the power plug 329 via the power cord 330.

Resonance capacitors 338 and 339 and the connection points of these resonance capacitors 338 and 339 A car rent transformer 340 to be contacted by, and a circuit protection thermo 341 to be mounted on either the inside of the inverter block 331. An induction heating coil 342 is further connected to one end side of the current transformer 340 in the inverter block 331 and the connection point of the switching elements 336 and 337, and a pan temperature detection thermistor is provided near the approximate center of the induction heating coil 342. 350 is provided. Incidentally, at the time of cooking, the coil units 31 and 32 themselves are moved to a position where the cooking container 20 can be induction heated via the top plate 13 by the high frequency magnetic field from the induction heating coil 342.

  The control block 332 includes a primary current detection circuit 345 connected to the current detection coil 344 in the inverter block 331, a power supply voltage detection circuit 346 for detecting a current supplied to the rectifier circuit 333, and at least the primary current detection.

Detection circuit 351 and temperature detection thermist And at least a pan temperature detection circuit 352 is connected to 350 and control circuit 347. 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. 4, these components are mounted inside the housing 305, and in particular, the inverter block 331 and the control block 332 are mounted on the mounting table 306. Further, 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.

  First, the detailed configuration of the inverter block 331 will be described.

  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. 4, 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 whose resistance value changes in accordance with a change in temperature. The circuit protection thermo 341 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. This pan temperature detection thermistor 350 is disposed near the center of the induction heating coil 342 as described above in order to detect the temperature of the cooking container 20 via the top plate 13.

  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, a detailed configuration of the control block 332 will be described.

  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. 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 plug 329. The power supply voltage detection circuit 346 notifies the control circuit 347 of the detected voltage.

  The control circuit 347 is configured by a CPU or the like. When the current value detected by the primary detection circuit 345 described above is notified 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 be electric power. 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 sends predetermined information via the display unit 363. indicate.

  The inverter drive circuit 348 is configured as an oscillation circuit for oscillating a sine wave signal, and generates the drive signal QA or the drive signal QB based on control by the control circuit 347.

  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. Then, the control circuit 347 can recognize this via the temperature detection circuit 349 and can stop the operation of the entire coil units 31 and 32.

  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, it is possible to stop the operation of the entire coil unit 3 and notify the user of this via the alarm 362.

  The pan temperature detection circuit 352 detects a change in resistance value in the pan temperature detection thermistor 350. The pan temperature detection circuit 352 detects the temperature of the cooking container 20 based on the detected change in the resistance value of the pan temperature detection thermistor 350. The pan temperature detection circuit 352 notifies the control circuit 347 of the detected temperature of the cooking container 20. 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. Thereby, when the temperature of the bottom part of the cooking container 20 rises more than a regulation value, for example, it also becomes possible to stop operation | movement of the coil unit 31 whole.

  The cooling fan 354 is rotated based on control by the control circuit 347. In accordance with the rotation of the cooling fan 354, the cooling air is sucked from the intake port 358. 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 display unit 363 is configured by a liquid crystal display surface or the like that displays predetermined information based on control by the control circuit 47.

  The operation unit 357 is embodied with keys, buttons, and the like for the user to actually operate the coil unit 31. The content input from the user in the operation unit 357 is notified to the control circuit 347, and the control circuit 347 controls each component of the coil unit 31 based on the input content. Incidentally, the operation unit 357 is assumed to be a button or the like formed on the surface of the housing 305. However, the operation unit 357 is not limited to such a case. For example, the operation unit 357 is for transmitting input content from a user by wireless communication. You may be comprised with the remote controller.

  Next, a description will be given of a method of actually heating the cooking container 20 by the coil unit 31 having the above-described configuration.

  First, a current for power supply 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.

  5A shows the resonance current flowing through the induction heating coil 342, FIG. 5B shows the drive signal QA supplied to the switching element 336, and FIG. 5C shows the switching element 337. The drive signal QB supplied with respect to is shown.

Inverter driver circuit 348, under the control of the control circuit 347, the drive time from the time point _{t 0} until the time point _{t 1} is ON outputs a drive signal QA is T1. 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. Incidentally, the inverter drive circuit 348 turns OFF the drive signal QA at time _{t 1.}

Then inverter driving circuit 348, under the 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.

  Next, the drawing operation of the base plate 32 in the system kitchen 1 to which the present invention is applied will be described.

  FIG. 6A shows a state where the base plate 32 is stored. In this case, when the operation button 21 is pressed by the user, an operation signal to that effect is generated and sent to the rotation drive unit 35 and the elevation control unit 38.

  In response to the operation signal, the elevation control unit 38 raises the vertically stored base plate 32. As a result, as shown in FIG. 6B, the base plate 32 is gradually pushed up from the upper end on the top plate 13.

  When the raising operation by the elevation control unit 35 is completed, the lower end of the top plate 13 is supported by the support mechanism in the arm 34, for example, as shown in FIG.

  Next, the arm 34 is rotated. This rotation operation may be performed manually by the user, or may be performed based on control by the rotation drive unit 35 that has received the operation signal. As a result, as shown in FIG. 6 (d), the base plate 32 turns from a substantially vertical direction to a substantially horizontal direction. Finally, as shown in FIG. 6 (e), the base plate 32 is placed horizontally on the top plate 13.

  Next, in the system kitchen 1 to which the present invention is applied, an operation for storing the base plate 32 placed horizontally on the top plate 13 as shown in FIG.

  First, the base plate 32 is pushed up. The pushing-up operation may be executed manually by the user.

  Moreover, you may make it perform based on control by the rotation drive part 35 which received the operation signal. When the operation button 21 is pressed by a user who desires to store the base plate 32, an operation signal to that effect is generated and sent to the rotation drive unit 35 and the elevation control unit 38. The rotation drive unit 35 receives the operation signal and rotates the arm 34. As a result, as shown in FIG. 6 (d), the base plate 32 turns from the horizontal direction to the vertical direction, and is erected in the vertical direction as shown in FIG. 6 (c). In this state, the base plate 32 is unsupported by the support mechanism in the arm 34, and is pushed down under the control of the elevation control unit 35, and is stored in the IH heater device 3 as shown in FIG. become.

  As described above, in the system kitchen 1 to which the present invention is applied, the base plate 32 can be taken out and stored only by pressing the operation button 21, and the user can reduce the labor of the user as much as possible. It is possible to freely change the thickness.

  Instead of providing the operation button 21 described above, an operation signal may be generated based on other means. For example, an infrared sensor (not shown) or the like may be used to detect a hand that has been provided by the user and generate an operation signal based on the detected hand.
