  Hereinafter, a preferred embodiment of the temperature control system of the present invention will be described with reference to the drawings. FIG. 1 is a diagram showing a system kitchen 1 to which a temperature control system 30 according to an embodiment of the present invention is applied.

  As shown in FIG. 1, the system kitchen 1 includes a base cabinet 2, a worktop 3, a sink 10, an electromagnetic cooker 11, and a temperature control system 30.

  The base cabinet 2 is a part installed on the floor, and a work top 3 as a top plate is attached to the top of the base cabinet 2. The work top 3 of the present embodiment is made of so-called artificial marble mainly composed of acrylic resin or polyester resin.

  The sink 10 is disposed at the center of the worktop 3, and an electromagnetic cooker 11 is disposed on one side across the sink 10, and a work space 12 is formed on the other side. In the work space 12, various operations such as cooking are performed, and cooking utensils such as a kitchen knife and a cutting board are temporarily placed.

  The temperature control system 30 is a temperature control system having a heating function and a cooling function. FIG. 2 is a diagram schematically showing how the container 110 is kept warm by the temperature control device 40. FIG. 3 is a diagram schematically illustrating how the container 120 is cooled by the temperature control device 40. FIG. 4 is a block diagram illustrating a state in which the temperature controller 40 is contactlessly powered.

  As shown in FIGS. 2 to 4, the temperature control system 30 includes a temperature control device 40 placed in the work space 12, and a power transmitter 70 that supplies power to the temperature control device 40.

  The temperature control device 40 is a heating / cooling device that heats the container 110 as an object or cools the container 120. The contents 115 of the container 110 to be heated are, for example, soup and pasta, and the contents 125 of the container 120 to be kept cold are juice and beer.

  The temperature control device 40 of the present embodiment is configured separately from the work top 3 and can be freely arranged in the work space 12. The work space 12 also functions as a heating / cooling area where heating or cooling is performed by the temperature control system 30.

  The configuration of the temperature control device 40 will be described. As shown in FIGS. 2 and 3, the temperature control device 40 includes a first heat conduction plate 41, a second heat conduction plate 42, a Peltier element 45, a switch 50, and a power receiver 60.

  The first heat conductive plate 41 is a portion that contacts the upper surface of the worktop 3 in the temperature control device 40, and is formed in a plate shape from a material such as aluminum.

  The second heat conduction plate 42 is a part that contacts the heating object (container 110) or the cooling object (container 120) in the temperature control device 40, and is formed in a lid shape with a lower part opened by a material such as aluminum. The The second heat conductive plate 42 has an outer shape that is larger than the first heat conductive plate 41 and covers a part of the first heat conductive plate 41.

  The second heat conductive plate 42 is formed in consideration of the size of the container 120 used for the temperature control system 30. In the present embodiment, the size of the second heat conductive plate 42 is set so as to fit inside the hill 111 of the container 110.

  The Peltier element 45 is disposed between the first heat conduction plate 41 and the second heat conduction plate 42, and heat is generated between the first heat conduction plate 41 and the second heat conduction plate 42 using the Peltier effect. Electronic parts to be moved. Electric power is supplied to the Peltier element 45 from the outside via the power receiver 60.

  The switch 50 is a switch that switches between heating and cooling. The switch 50 of this embodiment switches the direction of the heat transfer by the Peltier element 45 by switching the direction of the current supplied to the Peltier element 45.

  The power receiver 60 supplies the power received from the power transmitter 70 disposed on the worktop 3 side to the Peltier element 45.

  The power receiver 60 will be described. The power receiver 60 includes a power receiving coil 61 disposed so as to surround the outer surface of the first heat conducting plate 41, and a rubber heat insulating material 65 that covers the power receiving coil 61. Further, the power receiver 60 includes a capacitor and a rectifier circuit (both not shown) in addition to the power receiving coil 61, and the power receiving coil 61 and the capacitor are connected based on a resonance frequency set in a power transmitter 70 described later. Material, shape, capacity, etc. are selected.

  The rubber heat insulating material 65 covers the entire power receiving coil 61 and prevents the first heat conducting plate 41 and the second heat conducting plate 42 from coming into direct contact with each other while preventing the first heat conducting plate 41 and the second heat conducting plate 42 from coming into direct contact. The position of is fixed.

  The rubber heat insulating material 65 of this embodiment is fixed between the outer peripheral surface of the first heat conductive plate 41 and the inner peripheral surface of the second heat conductive plate 42. In a state where the temperature control device 40 is placed on the work top 3, the lower part of the rubber heat insulating material 65 (the power receiver 60) is not blocked by the first heat conduction plate 41 or the second heat conduction plate 42. It faces the upper surface.

  Next, power supply by the power transmitter 70 will be described. The power transmitter 70 is an LC circuit on the power transmission side having a power transmission coil 71 disposed on the back side of the worktop 3. As shown in FIG. 4, the power transmitter 70 is connected to an external power source 5, and a power switch 6 for turning ON / OFF the power supply to the power transmitter 70 is arranged on the system kitchen 1 side. Yes.

  The power transmission coil 71 that is bent into a rectangular shape according to the outer shape of the system kitchen 1 is fixed on the back side of the worktop 3. The resonance frequency set for the power transmitter 70 is set to match the resonance frequency of the power receiver 60 of the temperature control device 40.

  When power is supplied to the power transmitter 70, the power transmission coil 71 and the power reception coil 61 resonate and power is supplied from the power transmission coil 71 to the temperature control device 40 through the power reception coil 61 of the temperature control device 40 due to magnetic field resonance. The temperature control device 40 performs heating or cooling based on electric power supplied by non-contact power supply using magnetic field resonance.

  Next, the flow of heating and cooling of the object using the temperature control system 30 of the present embodiment will be described. First, the user turns on the power switch 6 of the system kitchen 1, switches the switch 50 of the temperature control device 40 to heating or cooling, and places the temperature control device 40 in the work space 12 of the worktop 3.

  When the user selects heating by the switch 50, the second heat conduction plate 42 side of the Peltier element 45 is the heat dissipation side, and the first heat conduction plate 41 side of the Peltier element 45 is the heat absorption side. The heat generated in the Peltier element 45 keeps the object to be heated through the second heat conduction plate 42. As shown in FIG. 2, heat can be transferred to the container 110 more efficiently by setting the container 110 so that the temperature control device 40 is placed inside the hill 111.

  When the user selects cooling by the switch 50, the second heat conduction plate 42 side of the Peltier element 45 is the heat absorption side, and the first heat conduction plate 41 side of the Peltier element 45 is the heat dissipation side. Heat is absorbed from the container 120 to be cooled by the Peltier element 45 via the second heat conducting plate 42.

  Since the first heat conduction plate 41 on the heat radiation side is in contact with the work top 3 having a large surface area, the work top 3 is radiated to cool the Peltier element 45 even when the Peltier element 45 having a large heat radiation amount is used. Since it can function as a plate, the object can be efficiently cooled.

  As shown in FIG. 3, the contents 125 of the container 120 can be sufficiently kept cold even in a container 120 such as a cup that does not have the height 111 on the bottom surface. Even during cooling, salads and sashimi can be kept cold using a container 110 as shown in FIG. In this case, heat can be absorbed more efficiently by disposing the temperature control device 40 inside the hill 111 as in the case of heating.

  Thus, heating / cooling of the temperature control device 40 is switched according to the purpose of the user. At the time of heating and cooling of the temperature control device 40, heat transfer occurs between the first heat conduction plate 41 and the second heat conduction plate 42 via the Peltier element 45. In the present embodiment, the first heat conduction plate 41 and the second heat conduction plate 42 The rubber heat insulating material 65 is arrange | positioned between the 2 heat conductive plates 42, and it has the structure where the 1st heat conductive plate 41 and the 2nd heat conductive plate 42 do not contact directly.

  Therefore, when heating is selected by the switching device 50, the first heat conducting plate 41 cooled by heat absorption takes heat from the second heat conducting plate 42, or when cooling is selected, heating is performed by heat dissipation. The situation in which the heat of the first heat conduction plate 41 thus moved moves to the second heat conduction plate 42 to prevent the cold insulation is prevented.

  According to the temperature control system 30 of the present embodiment described above, the following effects can be obtained. The temperature control system 30 of the present embodiment is provided inside the work top 3, and includes a power transmitter 70 having a power transmission coil 71 and a power receiving coil 61 that is configured separately from the work top 3 and resonates with the power transmission coil 71. And a temperature control device 40 having the same. The temperature control device 40 heats the container 110 or cools the container 120 by non-contact power supply from the power transmission coil 71 through the power reception coil 61 by magnetic field resonance.

  Thereby, since non-contact power feeding is performed from the power transmitter 70 to the temperature control device 40 using magnetic resonance, temperature control is performed at a location far from the power transmitter 70 as compared with a configuration in which power is supplied using electromagnetic induction. A device 40 can be placed. Further, it is possible to supply power to the plurality of temperature control devices 40 at the same time to perform heating or cooling, respectively.

  Further, since heating is not performed using electromagnetic induction, even if a metal material spoon or fork is placed on the work top 3, it is not heated against the intention of the user. In addition to a cutting board, a metal knife can be placed on the work top 3 where the power transmitter 70 is disposed, and the workability of the work top 3 is not impaired.

  In addition, the temperature control device 40 of the present embodiment is configured so that the current supplied through the power receiving coil 61 is energized to change the direction of the current flowing through the Peltier element 45 that heats or cools the containers 110 and 120 and the Peltier element 45. A switching device 50 for switching.

  Thereby, it is not necessary to prepare the structure for switching heating or cooling on the worktop 3 side, and the structure on the power transmission side can be simplified. Even when a plurality of temperature control devices 40 are used by simultaneous power feeding, the function of keeping the soup in one temperature control device 40 and keeping the beer in the other temperature control device 40 can be realized with a simple circuit configuration ( (See FIG. 1).

  In the present embodiment, a gap is formed between the first heat conduction plate 41 and the second heat conduction plate 42, and a rubber heat insulating material 65 is disposed in the gap so that the Peltier element 45 is interposed therebetween. In addition, a situation in which heat transfer directly occurs between the first heat conduction plate 41 and the second heat conduction plate 42 is reliably prevented. Further, the rubber heat insulating material 65 is inserted between the first heat conductive plate 41 and the second heat conductive plate 42 in an elastically deformed state, and serves as a seal member that prevents liquid from entering the temperature control device 40. Also works.

  In the present embodiment, the work top 3 as the top plate is formed of a material other than metal, and the temperature control device 40 is configured so that no metal material is interposed between the power receiver 60 and the work top 3. Yes. Thereby, the metal intervening between the power transmission coil 71 and the power reception coil 61 prevents a situation where power supply using magnetic field resonance is not properly performed.

  As mentioned above, although one preferable embodiment of the temperature control apparatus 40 of this invention was described, this invention is not restrict | limited to the above-mentioned embodiment, It can change suitably.

  For example, the power transmitter 70 is configured to supply power to the power receiving coil 61 with one power transmitting coil 71, but a plurality of power transmitting coils 71 may be provided. Two power transmission coils 71 bent in a rectangular shape can be arranged in parallel. In addition, a power transmission coil bent in a ring shape can be used instead of the power transmission coil 71 bent in a rectangular shape. Furthermore, the power transmission coil can be incorporated not inside the work top 3 but inside the work top 3. Thus, the arrangement method of the power transmission coil can be appropriately changed according to the place where the power transmitter is arranged, the heating or cooling target, and the like.

  In the above embodiment, the container 110 is heated or the container 120 is cooled by the temperature control device 40, but the present invention is not limited to this structure. For example, an elastic packing member may be disposed on the outer periphery of the second heat conductive plate 42 so that the container 110 is firmly held inside the hill 111. Further, the temperature control device may be a temperature control device in which a container having a container portion for storing contents and a temperature control device are integrally formed. Moreover, it can also be set as the structure which heats or cools the content directly with the temperature control apparatus 40, without passing through a container.

  In the above embodiment, the temperature control device 40 is configured to be able to switch between heating and cooling, but this function may be omitted. That is, the temperature control device can be a heating device that performs only heating or a cooling device that performs only cooling. Moreover, things other than a Peltier device can also be used as a heating device or a cooling device.

  In the said embodiment, although the power transmission device 70 is arrange | positioned in the system kitchen 1, the arrangement | positioning location of the power transmission device 70 can be changed suitably. For example, the temperature control system of the present invention can be applied to a place having various top plates such as a table and a bar counter.
