  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 putting other tableware and the space for processing food using a cutting board are inevitably reduced. Further, in the stove area B adjacent to the cooking stove unit area C, food or the like put in the pan 74 may be boiled at the same time using the gas stove 73, but the heat from the gas stove 73 is heated in the cooking stove unit area C. Since heat may be transferred to the cooking appliance placed above, further restrictions are imposed on the location of the cooking appliance.

  For this reason, it was necessary to implement | achieve this cooking more efficiently by making the space of the cooking-table unit area | region C or the stove area | region B variable according to a cooking method.

  Further, in the conventional system kitchen, since the power from the outlet is supplied to each cooking device via a cord, when many cooking devices are used at the same time, such a cord is placed on the cooking unit unit area C. It will be intricately intertwined. For this reason, restrictions are imposed on the space for placing other utensils on the counter unit area C, and it can be a great barrier in performing various operations such as cooking.

  In addition, for each cooking device to be placed on the cooking table unit area C, there may be a case where it is desired to arbitrarily adjust the position so that the arrangement and direction are most convenient for the user.

  However, the degree of freedom of the arrangement and orientation of each cooking appliance is governed only by the length of the cord connected to each cooking appliance, the position of the outlet provided in the system kitchen, and the like. For this reason, when the code | cord | chord connected to this cooking appliance is short etc., there exists a problem that the position of each cooking appliance cannot be adjusted so that it may become the most convenient arrangement | positioning and direction for a user.

  Further, when many cooking devices are used simultaneously on the cooking table unit area C, as shown in FIG. 17, the plug 67 is used in addition to the outlet 61 to each cooking device by so-called octopus foot wiring. Must supply power. Generally, the cords 68 and 70 inserted into these outlets are limited in the current that can be passed. Therefore, if a number of cooking utensils are connected and used simultaneously with octopus legs, the cords 68 and 70 are heated. May cause fire. In particular, when cooking utensils whose power consumption exceeds 1000 watts, such as a microwave oven and a dishwasher, are arranged on the cooking table unit area C, they can be connected by the above-described octopus foot wiring. In this case, the circuit breaker for wiring often breaks at any time, which is inconvenient. On the other hand, if the arrangement of cooking utensils with large power consumption on the cooking unit unit area C is restricted, the diversity of variations of cooking utensils that can be arranged cannot be increased. It also causes the efficiency of the system itself to drop.

  Therefore, the present invention has been devised in view of the above-described problems, and the object of the present invention is to make the space of the cooking table unit area C and the stove area B variable, and cooking equipment. It is possible to achieve free position adjustment in the cooking unit unit area without being controlled by the cord connected to the cable, and it is possible to operate many cooking utensils simultaneously without performing so-called octopus foot wiring.

When the identification signal is transmitted, a response signal for identifying the contact terminal is generated and the cordless electrical device transmits the response signal to the contact terminal unit. Based on the response signal transmitted from the electric device, the first contact surface and the contact on which the second contact surface is placed. With identifying the terminal, it invented cordless kitchen controlling so as to supply to the cordless electrical device the power current through the identified contact terminals.

  That is, the system kitchen according to the present invention is a cordless system kitchen having at least a work top or a counter (hereinafter referred to as a top plate), a plurality of contact terminals protruding from the top surface of the top plate, and a plurality of each A contact terminal unit having control means for transmitting identification signals via the contact terminals, and a current supply means for supplying current for power supply via the contact terminals based on control by the control means, and one or more contact terminals And when the identification signal is transmitted from the contact terminal via the first contact surface and the second contact surface.

At the same time, control is performed so that the current for power supply from the current supply means is supplied to the cordless electrical device via the specified contact terminal.

  Further, the system kitchen according to the present invention is a cordless system kitchen having at least a work top or a counter (hereinafter referred to as a top plate), and a plurality of contact terminals recessed in the upper surface of the top plate, and a plurality of contact terminals A contact terminal unit having control means for transmitting an identification signal via each contact terminal; and a current supply means for supplying a current for power supply via the contact terminal based on control by the control means; When the identification signal is transmitted from the contact terminal via the first protrusion and the second protrusion, and the first protrusion and the second protrusion, the contact terminal is specified. A cordless electrical device having a switching control means for generating a response signal for generating the response signal based on the identification signal and transmitting the response signal to the contact terminal unit. The control means in the contact terminal unit specifies the contact terminal into which the first protrusion and the second protrusion are fitted based on the response signal transmitted from the cordless electrical device, and Control is performed so that the current for power supply from the current supply means is supplied to the cordless electrical device via the specified contact terminal.

  The system kitchen according to the present invention transmits an identification signal through each of the plurality of contact terminals protruding on the top plate, and the identification signal from the contact terminal through the first contact surface and the second contact surface. Is transmitted to the cordless electrical device, a response signal for specifying the contact terminal is generated based on the identification signal and transmitted to the contact terminal unit. And the control part in a contact terminal unit specifies the contact terminal in which the 1st contact surface and the 2nd contact surface are mounted based on the response signal transmitted from the cordless type electric equipment, and AC power supply Is controlled so that the current for power supply is supplied to the cordless electrical device via the specified contact terminal.

  As a result, the power supply current is supplied to the cordless electrical device, and the power source current is applied to other devices connected to the cordless electrical device, such as a juicer, a toaster, and a rice cooker. Can be supplied.

  In particular, in this system kitchen, the cordless type electric device can receive the power supply current via the contact terminal unit without using the cord, so that many cordless type electric devices are arranged on the top board. Even in this case, the code is not complicated. For this reason, it is possible to secure a sufficient space for placing other appliances on the top board, and the cord does not become a barrier when performing various operations such as cooking.

  As long as the cordless electrical device is placed on the top plate, it can receive the power source current from any one of the contact terminals, so that it is possible to increase the degree of freedom of its arrangement and orientation. If the degree of freedom in arrangement and the like in this electronic device increases, the degree of freedom in arrangement in other devices connected thereto can be increased in the same manner, and the cooking device placed in the system kitchen is the most suitable for the user. It is also possible to freely adjust the position so as to provide a convenient arrangement.

  Furthermore, the system kitchen to which the present invention is applied is particularly effective when a large number of cooking devices are placed on the top plate and cooking is performed at the same time. In such a case, the cordless electrical device is placed on the top plate according to the number of cooking devices, and the cord is supplied by simultaneously supplying power current to the cordless electrical device individually. This can be realized without intervention. For this reason, even if the number of cordless electrical devices or other devices to be installed increases, it is no longer necessary to supply current for power supply by so-called octopus foot wiring as in the past, and a fire due to heating of the cord can be prevented. It can also be suppressed.

  Hereinafter, as the best mode for carrying out the present invention, a cordless 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”), and as shown in FIG. 1, a cabinet 11 and a cooking table unit in the cabinet 11.

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 faucet 15 causes water or hot water to flow out into the sink 14 via the faucet 17 in accordance with a rotation operation by the user. Thereby, it is also possible to cook in the sink 14 while flowing water from the faucet 17. Incidentally, when not flowing water, the faucet 17 may be rotated in the direction E in the figure. Thereby, it becomes possible to cook using the inside of the sink 14 without using the faucet 17 as a barrier.

  The contact terminal unit 5 is mounted in the cabinet 11 or the top plate 13. Circuits to be described later that are mounted in the contact terminal unit 5 can be configured extremely compactly by being integrated, and can be easily mounted in the cabinet 11 or the top plate 13. It becomes.

The AC power supply 83 can finely adjust the actual voltage by a transformer in which a conducting wire is wound in a coil shape. The magnitude of the power supply current output from the AC power supply 83 can be controlled by the control unit 81 at a fine pitch. The AC output from the AC power source 83 is sent to the contact terminal 27 designated by the control unit 81 via the switching unit 85.

  Next, a block configuration of the electric device 4 applied as an example will be described.

  For example, as shown in FIG. 3, the electrical device 4 includes a switching circuit 46 connected to the first contact surface 41 and the second contact surface 42, and the switching circuit 46 and the second contact surface 42. A connected outlet 47 is provided.

  The switching circuit 46 receives the identification signal P from the contact terminal 27 with which the first contact surface 41 is in contact. Further, the switching circuit 46 receives an identification signal P from the contact terminal 27 with which the second contact surface 42 is in contact. The switching circuit 46 uses a response signal D for specifying the contact terminal 27 in contact with the first contact surface 41 and the contact terminal 27 in contact with the second contact surface 42 based on the identification signal P. To generate. The switching circuit 46 sends the generated response signal D to the contact terminal unit 5 via the contact terminal 27 in contact with the first contact surface 41 and the contact terminal 27 in contact with the second contact surface 42. Send.

  The outlet 47 is inserted with a plug (not shown) provided at the end of a cord connected to another device. When the plug (not shown) is inserted, the output terminal provided in the outlet section 47 itself is electrically connected thereto. The outlet 47 supplies a power supply current supplied from the AC power supply 83 in the contact terminal unit 5 through an inserted plug (not shown). Thereby, it becomes possible to supply the electric current for power produced in the inside of the contact terminal unit 5 to another apparatus via the electric apparatus 4 as an adapter. Incidentally, the outlet portion 47 may be formed in plural in the electric device 4. In such a case, the switching circuit and the contact surfaces 41 and 42 are formed according to the number of outlet portions.

Next, the operation of the system kitchen 1 to which the present invention is applied will be described. Incidentally, in the description of this operation, the contact terminals 27 projecting from the top plate 13, the contact terminals _{27 H1-H4} as shown in FIG. 3, the contact terminal _{27 I1 to I4,} contact terminals _{27 J1 through J4,} contact The case where the arrangement _| sequence of terminal 27 _K1-K4 and contact terminal 27 _L1-L4 is included is mentioned as an example.

  First, when no electrical device 4 is placed on the top board 13, the control unit 81 generates an identification signal P at a predetermined time interval and transmits it to each contact terminal 27. As a result, each contact terminal 27 is in a state where an identification signal P is sent at a predetermined interval. However, since no electrical device 4 is placed on the top plate 13, the contact terminal 27 is only in one direction. The transmission of the identification signal P is repeated endlessly.

Next, as a result of placing the electrical device 4 on the top plate 13, as shown in FIG. 5, the first contact surface 41 contacts the contact terminal _27I2 , and the second contact surface 42 contacts the contact terminal 27. when in contact with _J2, the identification signal P transmitted from the control unit 81 is transmitted to the first contact surface 41 via the contact terminals 27 _I2, the second contact surface 42 via the contact terminals 27 _J2 Sent.

The identification signal P transmitted to the first contact surface 41 is sent to the switching circuit 46 as it is. Based on the identification signal P, the switching circuit 46 generates a response signal D indicating that the contact terminal 27 _I2 is in contact with the first contact surface 41. The control signal P transmitted to the second contact surface 42 is sent to the switching circuit 46 as it is. Based on the identification signal P, the switching circuit 46 generates a response signal D indicating that the contact terminal 27 _J2 is in contact with the second contact surface 42. Each response signal D generated in the switching circuit 46 is again projected on the top plate 13 via the first contact surface 41 and the second contact surface 42 along the same route or a different route. It is transmitted to the contact terminal 27 _I2 and the contact terminal 27 _J2 , and from there to the control unit 81.

The control unit 81 receives the response signal D, and based on these signals, the contact terminal 27 _I2 , the contact terminal 27 as the contact terminal 27 on which the first contact surface 41 and the second contact surface 42 are placed. _{Specify J2} . In addition, the control unit 81 performs control so that the power supply current is supplied to the electric device 4 only through the specified contact terminal 27 _I2 and contact terminal 27 _J2 . In such control, first, the control unit 81 instructs the AC power supply 83 to supply power supply current, and the switching unit 85 is switched based on the control by the control unit 81, thereby The setting is changed so that the power supply current is supplied only to the contact terminal 27 _I2 and the contact terminal 27 _J2 .

As a result, the power supply current from the AC power source 83, the contact terminals _{27 I2,} is supplied to the contact terminals _{27 J2,} these contact terminals _{27 I2,} contact terminals _{27 J2} to a first contact surface 41 and a second that contact It is sent to the electric device 4 through the contact surface 42. The power supply current sent to the electrical equipment 4 is output directly to the outlet section 47 or indirectly through the switching circuit 46 and used as a power source for other equipment connected to the outlet section 47. Will be. The switching circuit 46 may perform switching control so that when the current for power supply is supplied from the contact terminal unit side via the contact terminal 27, it is sent to the outlet unit 47.

  In addition, it is not limited to the case where the contact terminals 27 contact the first contact surface 41 and the second contact surface 42 one by one as described above, but the first contact surface 41 and the second contact surface. Even when the plurality of contact terminals 27 are in contact with the surface 42, the power source current can be supplied to the electric device 4 based on the same operation.

For example, as a result of the electrical device 4 being placed on the top plate 13, as shown in FIG. 6, the first contact surface 41 contacts the contact terminal 27 _I2 and the contact terminal 27 _I3 , and the second contact surface 42 Is in contact with the contact terminal 27 _J2 and the contact terminal 27 _J3 , the identification signal P transmitted from the control unit 81 is transmitted to the first contact surface 41 via the contact terminal 27 _I2 and the contact terminal 27 _I3 . It is transmitted to the second contact surface 42 via the contact terminal 27 _J2 and the contact terminal 27 _J3 .

The identification signal P transmitted to the first contact surface 41 via the contact terminal 27 _I2 and the contact terminal 27 _I3 is sent to the switching circuit 46 as it is. Based on the identification signal P, the switching circuit 46 generates a response signal D indicating that the contact terminals 27 _I2 and 27 _I3 are in contact with the first contact surface 41. Similarly, the control signal P transmitted to the second contact surface 42 via the contact terminals 27 _J2 and 27 _J3 is sent to the switching circuit 46 as it is. Based on the identification signal P, the switching circuit 46 generates a response signal D indicating that the contact terminals 27 _J2 and 27 _J3 are in contact with the second contact surface 42. Each response signal D generated in the switching circuit 46 is again projected on the top plate 13 via the first contact surface 41 and the second contact surface 42 along the same route or a different route. The contact terminal 27 _I2 , the contact terminal 27 _I3 , the contact terminal 27 _J2 , and the contact terminal 27 _J3 are transmitted to the control unit 81.

The control unit 81 receives the response signal D, and based on these signals, the contact terminal 27 _I2 , the contact terminal 27 _I3 , and the contact terminal 27 on which the first contact surface 41 and the second contact surface 42 are placed. _J2 and contact terminal 27 _J3 are specified. In addition, the control unit 81 controls the power supply current to be supplied to the electrical device 4 only to the specified contact terminal 27 _I2 , contact terminal 27 _I3 , contact terminal 27 _J2 , and contact terminal 27 _J3 . As a result, the power supply current from the AC power supply 83 is supplied to the contact terminal 27 _I2 , the contact terminal 27 _I3 , the contact terminal 27 _J2 , and the contact terminal 27 _J3, and passes through the first contact surface 41 and the second contact surface 42. It is sent to the electric equipment 4 via That is, even when there are a plurality of contact terminals 27 that contact the first contact surface 41 and the second contact surface 42, it is possible to supply a power supply current in the same manner.

In the system kitchen 1, even in the case where a plurality of electrical devices 4 are placed on the top plate 13, it is possible to supply a power supply current based on the same method. For example, as shown in FIG. 7, the first contact surface 41 in the electric device 4A is in contact with the contact terminal 27 _I2 , the second contact surface 42 is in contact with the contact terminal 27 _J2 , and the first contact surface 41 in the electric device 4B is When the second contact surface 42 is in contact with the contact terminal 27 _L3 and the contact terminal 27 _K3 , the response signal D indicating that the contact is made to the contact terminal 27 _I2 and the contact terminal 27 _J2 from the electric device 4A is A response signal D indicating that the device 4B is in contact with the contact terminal 27 _K3 and the contact terminal 27 _L3 is transmitted to the control unit 81. After identifying the response signal D, the control unit 81 identifies the contact terminal 27 with which the first contact surface 41 and the second contact surface 42 of the electric devices 4A and 4B are in contact with each other. Thus, control is performed so that a current for power supply is supplied.

  As described above, in the system kitchen 1 to which the present invention is applied, the identification signal P is transmitted through each of the plurality of contact terminals 27 protruding on the top board 13, and the first contact is made from the contact terminal 27. When the identification signal P is transmitted to the electric device 4 through the surface 41 and the second contact surface 42, a response signal D for specifying the contact terminal 27 is generated based on the identification signal P. At the same time, this is transmitted to the contact terminal unit 5. Then, the control unit 81 in the contact terminal unit 5 specifies the contact terminal 27 on which the first contact surface 41 and the second contact surface 42 are placed based on the response signal D transmitted from the electrical device 4. At the same time, control is performed so that the power source current from the AC power source 83 is supplied to the electrical device 4 through the specified contact terminal 27.

  As a result, a current for power supply is supplied to the electric device 4, and the power supply current is also supplied to other devices connected to the electric device 4, such as a juicer, a toaster, and a rice cooker. It becomes possible to do.

  In particular, in this system kitchen 1, since the electric device 4 can receive the current for power supply via the contact terminal unit 5 without using a cord, many electric devices 4 are arranged on the top plate 13. In this case, the code is not complicatedly entangled. For this reason, it is possible to secure a sufficient space for placing other instruments on the top board 13, and the cord does not become a barrier when performing various operations such as cooking.

  FIG. 8 shows a configuration in a case where the electric device 4 can be attached to another device 110 such as a juicer. As shown in FIG. 8, a mounting portion 50 having a relatively simple configuration including a magnet, a clip, and the like is provided in the electric device 4 and is detachable from the other device 110 such as a juicer through the mounting portion 50. Thus, the plug 112 at the tip of the cord 111 extended from the other device 110 can be directly connected to the outlet portion 47 of the electric device 4. Thereby, the cord 111 is not entangled on the top plate 13, and the space of the top plate 13 can be utilized more efficiently.

  In some cases, the electric device 4 and other devices connected to the electric device 4 may desire arbitrary position adjustment so that the arrangement and direction are most convenient for the user.

  Even in such a case, since the electric device 4 can receive the current for power supply from any of the contact terminals 27 as long as it is placed on the top board 13, the degree of freedom in the arrangement and direction can be increased. It becomes possible. If the degree of freedom in arrangement and the like in the electronic device 4 is increased, the degree of freedom in arrangement in other devices connected to the electronic device 4 can be increased in the same manner, and a cooking device placed in the system kitchen 1 can be used by the user. It is also possible to freely adjust the position so as to be the most convenient arrangement for the user.

  Furthermore, the system kitchen 1 to which the present invention is applied is particularly effective when a large number of cooking devices are placed on the top plate 13 and cooking is performed simultaneously. In such a case, the electric device 4 is placed on the top plate 13 in accordance with the number of cooking devices, and a current for power supply is individually supplied to the electric device 4 at the same time. This can be realized without any problem. For this reason, even if the number of electrical devices 4 or other devices to be arranged increases, it is no longer necessary to supply current for power supply by so-called octopus leg wiring as in the past, and the occurrence of fire due to heating of the cord is suppressed. It is also possible to do. In particular, even when cooking utensils whose power consumption exceeds 1000 watts, such as a microwave oven and a dishwasher, are arranged by connecting them to the electric device 4 as an adapter, the octopus leg wiring as described above There is no need to perform the process, and convenience can be improved.

  That is, in the present invention, the cooking device placed on the top plate 13 can be connected to the electric device 4 regardless of the amount of power consumption. It is possible to increase the variety of variations of various devices and to further improve the efficiency of cooking itself. In particular, while many recipes are being studied, in recent years when a wide variety of cooking, with a variety of Japanese, Western, and Eastern styles, has become feasible at home, it is possible to operate many cooking devices on the top plate 13 simultaneously. The present invention that can be said to be particularly useful.

  As a method for generating the response signal D in the switching circuit 46, for example, the identification signal P transmitted through the first contact surface 41 / second contact surface 42 is used as the response signal D as it is. May be transmitted to the contact terminal unit 5 via the contact surface 42 / first contact surface 41.

For example, the contact terminals _{27 I2} comes into contact with the first contact surface 41 as shown in FIG. 9 (a), when the contact pin _{27 J2} to the second contact surface 42 is in contact, such contact terminals _{27 I2} from via the first contact surface 41 receives the identification signal P, and transmits it to the response signal D as the second contact surface 42 contact terminals 27 _J2 in contact with. Similarly, the identification signal P is received from the contact terminal 27 _J2 through the second contact surface 42 and is transmitted as it is as the response signal D to the contact terminal 27 _I2 in contact with the first contact surface 41.

As a result, a response signal D as a signal similar to the identification signal P is transmitted to the control unit 81 via the contact terminal 27 _I2 and the contact terminal 27 _J2 . The control unit 81 identifies from which contact terminal 27 the response signal has been transmitted via the input / output unit 91. Finally, the control unit 81 can identify that the contact surfaces 41 and 42 are in contact with the contact terminal 27 _I2 and the contact terminal 27 _J2 , respectively.

  Thus, in the system kitchen 1 to which the present invention is applied, by returning the identification signal P transmitted to the switching circuit 46 as it is to the contact terminal unit 5 as the response signal D, the contact surfaces 41 and 42 are The contact terminal 27 that is in contact can be easily identified. For this reason, it is not necessary to provide a particularly complicated circuit configuration on the switching circuit 46 side in the electrical device 4, and it is sufficient to implement a cheaper and simpler configuration, so that the general versatility of the entire system can be improved. .

  In addition, by mounting a CPU (not shown) for identifying the contents of the identification signal P in the switching circuit 46, the first contact surface 41 and the second contact surface 42 are contacted from the supplied identification signal P. It is also possible to identify the contact terminal 27 that is being used, include the identified contact terminal 27 in the response signal D, and return this to the contact terminal unit 5.

In such a case, the control unit 81 generates different identification signals P between the contact terminals 27 and transmits them to the contact terminals 27. Control unit 81 in such a case, for example, for the contact terminal _{27 H1-H4,} an identification signal _{P H1-H4} respectively supplied, for the contact terminal _{27 I1 to I4,} an identification signal _{P I1 to I4} Identification signals P _J1 to _J4 are supplied to the contact terminals _J1 to _J4 , respectively, and different identification signals P are supplied to the remaining contact terminals 27, respectively. Incidentally, the identification signal P may be different from each other by changing the pulse train, for example, or may be different from each other in frequency.

When the electric device 4 is placed on the top plate 13 on which the contact terminals 27 supplied with such identification signals P are projected, for example, as shown in FIG. 41, when the contact terminal 27 _I2 is in contact with the second contact surface 42 and the contact terminal 27 _J2 is in contact with the second contact surface 42, the switching circuit 46 receives the identification signal P _I2 from the contact terminal 27 _I2 and the contact terminal 27 _J2. The identification signal _PJ2 is supplied.

A CPU (not shown) in the switching circuit 46 identifies the identification signal P _{I2 and the} identification signal P _J2 . As a result, the switching circuit 46 itself can recognize that the contact terminal 27 _I2 is in contact with the first contact surface 41 and the contact terminal 27 _J2 is in contact with the second contact surface 42 at the present time. For example, when the pulse trains are changed between the identification signals P to make them different from each other, the recognition may be performed by the switching circuit 46 reading the pulse trains.

The switching circuit 46 recognizes the identification signal P and generates a response signal D corresponding thereto. The response signal D to be the product, for example a response signal _{D27 I2} for notifying is in contact with the contact terminal _{27 I2,} and the response signal _{D27 J2} for notifying that in contact with the contact terminal _{27 J2} There is. The response signal D27 _I2 and the response signal D27 _J2 are transmitted to the control unit 81 in the contact terminal unit 5 via the contact terminal 27 _I2 and the contact terminal 27 _J2 , respectively. The control unit 81 that has received the response signal D27 _I2 and the response signal D27 _J2 contacts the first contact surface 41 with the contact terminal 27 _{I2 and} contacts the second contact surface 42 with the contact terminal 27 _J2 at the present time. Can be identified. For this reason, the control part 81 can perform control so that the electric current for power supplies is supplied to the electric equipment 4 via the contact terminal 27 _I2 and the contact terminal 27 _J2 .

  In this way, the identification signals P transmitted for the respective contact terminals 27 are made different from each other, and the identification signals P are recognized through a CPU (not shown) provided on the switching circuit 46 side, so that the response signal D corresponding thereto is obtained. And transmitting this to the control unit 81, it is also possible to supply the current for power supply to the pin point via the contact terminal 27 in contact with each contact surface 41, 42. Particularly in this example, an IC including a CPU is mounted in the switching circuit 46 in addition to the control unit 81, but the identification signal P read on the switching circuit 46 side There is a greater effect in that it can be used for control, and it is useful in that the response signal D to be transmitted can be generated more reliably.

  The present invention is not limited to the embodiment described above. For example, as shown in FIG. 10, a rectifier circuit 87 for rectifying a current for power supply from the connected AC power supply 83 and a smoothing circuit 88 connected to the rectifier circuit 87 are mounted in the contact terminal unit 5 to the last. You may make it do.

  The rectifier circuit 87 is a circuit for converting a power supply current as an alternating current output from the alternating current power supply 83 into a direct current. This rectifier circuit 87 is configured by a so-called full-wave rectifier circuit configured by connecting four diodes in a bridge shape, but is not limited to this, and is configured by a half-wave rectifier circuit using only one diode. May be.

  The smoothing circuit 88 is configured by connecting a capacitor and a coil. By passing the power supply current through the smoothing circuit 88, the size can be made constant.

  As described above, by mounting the rectifier circuit 87 and the smoothing circuit 88 in the contact terminal unit 87, the power supply current supplied to the electrical equipment 4 has already been converted into direct current and the magnitude is further adjusted to be constant. It has become a state. For this reason, a stable power supply current is supplied from the contact terminal unit 5 even when a device that is currently available to the general public is connected to the electrical device 4 as it is. This eliminates the need to provide such a rectifier circuit or smoothing circuit on the electric device 4 side or on the other device side connected to the electric device 4, thereby reducing the cost of the system. Furthermore, the general versatility of the entire system can be improved.

  In the present invention, for example, the contact terminal 27 is formed with a surface 27a that can contact the first contact surface 41 and / or the second contact surface 42 substantially in parallel as shown in FIG. May be. Thus, when the first contact surface 41 or the second contact surface 42 contacts the surface 27a of any one of the contact terminals 27, a surface 27a substantially parallel to the surface 27a is shown in FIG. Thus, the contact surface 41 comes into close contact. By increasing the area of the surface 27a, the contact area with the contact surfaces 41 and 42 can be increased. If this contact area can be increased, the electrical resistance can be reduced. If the electrical resistance between the contact terminal 27 and the contact surfaces 41 and 42 can be reduced, a large amount of power source current can be supplied to the electrical device 4, and a device with high power consumption can be replaced with the electrical device. Even in the case of connection to 4, the entire system can be stably operated. Incidentally, although this contact area is assumed to be 5 mm × 5 mm, it is not limited to this size, and any contact area may be used.

  In the above-described embodiment, the case where the electric device 4 is applied as an adapter has been described as an example. However, as described below, the electric device 4 may be applied to a heat and cold insulation device for cooling or heating a dish. .

  FIG. 12 is a perspective view of an electric device 9 applied as a cold insulation apparatus, FIG. 13 is a side view of the electric device 9, and FIG. 14 shows a block configuration of the electric device 9. The electrical device 9 has a plate 31 on which food or a container for containing food is placed, a Peltier element 32 that cools or heats the plate 31 from the inside, and a current when the Peltier element 32 is operated. The switching circuit 33 for controlling, the first contact surface 41 and the second contact surface 42 respectively connected to the switching circuit 33, and the temperature of the dish placed on the plate 31 or the container containing the dish A temperature detection sensor 34 for detecting the temperature, a fan 36 for sending air for cooling the heat radiating portion 35 of the Peltier element 32, control buttons 37a to 37e for the user to execute various controls, and a temperature for the plate 31. The display unit 38 and a control unit 39 for performing necessary control such as temperature control for controlling the entire electric device 9 are mounted inside the housing 118. That.

  The heat from the fan 36 is discharged to the heat radiating portion 35 below the Peltier element 32 through the exhaust holes 60 formed between the fins 40. The fan 36 may be used to dissipate the surface of the heat radiating portion 35 of the Peltier element 32. The configuration of the fan 36 may be omitted.

  A temperature detection sensor 34 provided on the back surface of the plate 31 detects the temperature of the plate 31. In addition, the temperature detection sensor 34 transmits the detected temperature information to the control unit 39.

  The control unit 39 identifies temperature information transmitted from the temperature detection sensor 34. Then, the control unit 39 compares the temperature of the cooling plate represented as the temperature information with the temperature set by the user via the control button 37, and increases the output voltage according to the comparison result. A control signal or a control signal for reducing the output voltage is generated.

  The switching circuit 33 is connected to the first contact surface 41 and the second contact 42 in the same manner as the switching circuit 46 described above, and is supplied from the contact terminal unit 5 via the contact terminal 27 in contact therewith. The magnitude of the power supply current is adjusted based on the control signal sent from the control unit 39. In addition, the switching circuit 33 supplies the power source current with the adjusted magnitude to the Peltier element 32. The Peltier element 32 absorbs or releases heat from the plate 31 based on the supplied power supply current, and the temperature of the plate 31 increases or decreases accordingly.

  Further, the temperature of the plate 31 is notified to the control unit 39 as temperature information via the temperature detection sensor 34, and the above-described operation is repeated. As a result, feedback control can be performed until the temperature of the plate 31 reaches the temperature set by the user.

  In addition, in this electrical apparatus 9, in addition to being able to arbitrarily set the cooling temperature and heating temperature of the dish or vessel placed on the plate 31 via the control button 37, the cooling time and heating time can also be arbitrarily set. can do. For example, when the cooling time is set by the user to be short, the control unit 39 increases the temperature from the temperature of the plate 31 based on the temperature information generated by the temperature detection sensor 34 to the temperature specified by the user. A control signal is generated so as to have a temperature gradient. As a result, when the amount of heat absorbed (released) from the plate 31 by the Peltier element 32 increases, the plate 31 rapidly approaches the temperature specified by the user.

  On the other hand, when the cooling time is set by the user to be long, the control unit 39 changes the temperature of the plate 31 based on the temperature information generated by the temperature detection sensor 34 to the temperature specified by the user. A control signal is generated so as to have a small temperature gradient. As a result, the amount of heat absorbed (released) from the plate 31 by the Peltier element 32 decreases, and the plate 31 slowly approaches the temperature specified by the user.

  The control unit 39 may display the temperature information notified from the temperature detection sensor 34 through the display unit 38 as needed. In addition, any one of the control buttons 39 has a function of switching between heating and cooling of the plate 31 so that the user can easily switch between heating and cooling by one pressing operation of the control button 37 by the user. It becomes.

  As described above, in the system kitchen 1 to which the present invention is applied, when the electric device 9 as a heat insulating and cold-retaining device is placed on the top plate 13, a plurality of each of the contacts protruding from the top plate 13 is provided. When the identification signal P is transmitted via the terminal 27 and the identification signal P is transmitted from the contact terminal 27 via the first contact surface 41 and the second contact surface 42, A response signal D for specifying the contact terminal 27 is generated based on the identification signal P and transmitted to the contact terminal unit 5. Then, the control unit 81 in the contact terminal unit 5 specifies the contact terminal 27 on which the first contact surface 41 and the second contact surface 42 are placed based on the response signal D transmitted from the electrical device 9. At the same time, control is performed so that the power source current from the AC power source 83 is supplied to the electrical device 4 through the specified contact terminal 27.

  As a result, a power source current is supplied to the electric device 9, and it becomes possible to secure a power source for heating and cooling by the Peltier element 32 without using a cord.

  In particular, in the system kitchen 1, as shown in FIG. 15, even when a large number of electric devices 9 having the above-described configuration are placed, the cords are not complicatedly entangled. For this reason, it is possible to secure a sufficient space for placing other instruments on the top board 13, and the cord does not become a barrier when performing various operations such as cooking. Moreover, in this system kitchen 1, since it becomes possible to operate | move this only by mounting the electric equipment 9 in the cooking-unit unit area | region C where the top plate 13 was stuck, gas stove like the past It is no longer necessary to separately provide a stove area B for mounting.

  In particular, according to the present invention, according to the needs of the user, it is possible to place many electrical devices 9 on the top plate 13 to perform simultaneous heating and cooling of food, or widen the top plate 13 widely. It is also possible to process ingredients using them. In other words, the space of the cooking unit unit area C and the stove area B for actual cooking can be made variable on the top plate 13. Compared to the conventional system kitchen in which the cooking unit unit area C and the stove area B are specified as in the conventional case, the space can be used more effectively, and the user can further use these electric devices 4 and 9. It is also possible to enjoy variations of the arrangement.

  In this electrical apparatus 9, as an alternative to the above-described Peltier element 32, for example, an IH coil or a radiator heater coil may be provided. In such a case, the configuration of the rectifier circuit 87 and the smoothing circuit 88 is particularly necessary. However, these may be mounted in the contact terminal unit 5 as described above, or may be mounted in the electric device 9. May be.

  Thus, in the system kitchen 1 to which the present invention is applied, in addition to the configuration in which a device that relays power to be supplied, such as the electrical device 4 as an adapter, is sandwiched between other devices, As described above, this may be realized by mounting the contact surfaces 41 and 42 and the switching circuit 33 in an actual cooking device.

  Incidentally, in the case where the electric device 9 is applied as another device in addition to being applied as a heat insulation / cooling device, this is realized by mounting the same configuration. Since the configuration of each contact surface 41, 42 and switching circuit 33 is a very inexpensive and simple configuration, it is possible to suppress labor and cost as much as possible even when mounted on other devices, and increase versatility. Is possible.

  In the system kitchen 1 to which the present invention is applied, the contact terminal 27 is recessed on the top surface of the top plate 13, and the recessed contact terminal is used as an alternative to the first contact surface 41 and the second contact surface 42. A first protrusion and a second protrusion (not shown) that can be fitted to the terminal 27 may be provided on the electric device 4 side.
