Definitions

  • the present disclosure relates to induction heating cookers to be used for home cooking and professional cooking.
  • An induction heating cooker includes, in general, at least one heating coil directly under a top plate on which a metallic cooking utensil (e.g. pan) is to be placed.
  • the induction heating cooker allows the heating coil to give off a high-frequency magnetic field, which generates an eddy current to the cooking utensil placed on the top plate. As a result the cooking utensil is heated for carrying out a cooking.
  • Patent literature 1 discloses the following induction heating cooker: In order to drive multiple heating coils with a single drive circuit, this induction heating cooker allows controlling the drive circuit such that a current path to the heating coils can be connected or disconnected with relays for avoiding useless supply of high-frequency current to heating coils not in use.
  • Patent literature 2 discloses an induction heating cooker in which multiple relays are integrated for improving an assembling efficiency.
  • Patent literature 3 discloses an induction heating cooker in which a number of heating coils are arranged in matrix below a cooking utensil, and a single drive circuit supplies a high-frequency current to the heating coils.
  • the wiring work to the heating coils is regularly done this way: First, the drive circuit is built into a housing of the induction heating cooker, then the wiring work is done with the heating coils being temporarily placed around the housing or special jigs to this wiring work. The wiring work becomes thus complicated in proportion to the number of the heating coils. On top of that, since the wirings are temporarily prepared, lead wires such as connection wires to the heating coils should be longer than necessary.
  • the wiring work discussed above not only incurs an increase in the cost, but also possibly invites damages to the lead wires because of stress applied to the lead wires, or due to an unexpected contact of the lead wires to components inside the housing. On top of that, since the lead wires are shaped longer than necessary, it should be noted that noises given off by the heating coils may adversely affect the drive circuit.
  • EP 2 427 032 A2 relates to a hob plate device.
  • the device has a heating element carrier unit i.e. aluminum plate, for holding a heating element i.e. induction heat bodies, and an electronic carrier unit for holding an electronic unit.
  • the heating element carrier unit and a part of the electronic unit are arranged on different sides of the electronic carrier unit.
  • the electronic carrier unit partially encompasses an accommodation area for the electronic unit.
  • the heating element carrier unit includes cable feedthroughs present in an outer area for feeding power supply cables of the heating element.
  • An independent claim is also included for a method for assembling a hob device i.e. induction hob device.
  • DE 100 11 773 A1 relates to an induction heating cooker.
  • the device has at least one induction coil, at least one induction coil bearer, at least one control unit for applying a high frequency operating voltage to the coil with a converter connected to a low frequency source and at least one screening device between the induction coil and the bearer.
  • the screening device is electrically conducting and is electrically connected to the control unit at a low frequency junction.
  • EP 2 475 220 A1 relates to a hob plate device.
  • the device comprises shielding elements and cover unit.
  • EP 2 595 450 A2 relates to a cooking device.
  • the device has a multi-function component for cooling a power unit of a domestic appliance and shielding the power unit against electrical and/or magnetic fields, where a main structure component is provided in the device.
  • the multi-function component is integrally formed and manufactured using an injection molding method.
  • the multi-function component is made of aluminum or aluminum alloy and comprises two cooling fins and a receiving area that receives a main function unit of the appliance.
  • the multi-function component forms a part of an outer housing.
  • the invention is defined by the subject-matter of independent claim 1.
  • the dependent claims are directed to advantageous embodiments.
  • an induction heating cooker includes a drive circuit, multiple heating coils, and a relay circuit.
  • the drive circuit converts an AC power supply to high-frequency electric power.
  • the multiple heating coils are disposed to a metallic shielding plate, and generate a high-frequency magnetic field upon receiving the high-frequency electric power.
  • the relay circuit includes multiple relays that switch connections between the drive circuit and the multiple heating coils in response to a signal supplied from the drive circuit. This relay circuit is coupled to the heating coils via connection wires, and is disposed to a holder which is mounted to the shielding plate on an opposite face to the face where the heating coils are disposed.
  • the induction heating cooker in which the connection between the multiple heating coils and the drive circuit is switched by using the relays, allows achieving the wiring with ease between the heating coils and the relay circuit, as well as between the relay circuit and the drive circuit.
  • these wirings can be done free from changes in length of the connection wires to the heating coils.
  • noises can be reduced, and the assembling efficiency is improved.
  • the number of components to be shaped individually, which is a troublesome work can be reduced.
  • An induction heating cooker in accordance with a first aspect of the present disclosure includes a drive circuit, multiple heating coils, and a relay circuit.
  • the drive circuit converts an AC power supply to high-frequency electric power.
  • the multiple heating coils are mounted to a metallic shielding plate, and generate a high-frequency magnetic field upon receiving the high-frequency electric power.
  • the relay circuit includes multiple relays that switch connections between the drive circuit and the multiple heating coils in response to a signal supplied from the drive circuit. This relay circuit is coupled to the heating coils via a connection wire, and is disposed to a holder which is mounted to the shielding plate on a face opposite to the face where the heating coils are mounted.
  • This first aspect proves that a wiring work is firstly done between the relay circuit and the heating coils, and then a wiring work can be done between the relay circuit and the drive circuit. As a result, the induction heating cooker can be assembled with more ease.
  • the first aspect proves that the heating coils can be brought closer to the relay circuit when the heating coils are connected to the relay circuit.
  • the connection wires thus need not to be shaped uselessly long, so that the noises given off by the heating coils can be reduced.
  • the first aspect proves that if the shielding plate becomes hot due to the heat from the heating coils, the holder protects the relay circuit from the heat given off by the shielding plate.
  • the first aspect proves that if the location of the heating-coil unit in the housing is changed, no change is needed in a distance between the heating coils and the relay circuit within the heating-coil unit.
  • the length of the connection wire does not depend on the location of the heating-coil unit. This structure allows the connection wires of the same length can be commonly used for other models in which the heating coil units are placed in different places from each other.
  • An induction heating cooker in accordance with a second aspect of the present disclosure includes a connection wire that is wired via an opening formed on the shielding plate for connecting the heating coils and the relay circuit together. This is a different point from the first aspect.
  • the structure of the second aspect allows using a connection wire shorter than the connection wire taking a long way around the shielding plate.
  • An induction heating cooker in accordance with a third aspect of the present disclosure includes a holder that has a stationary section to be joined mechanically to the housing, and this holder is disposed around an edge of the shielding plate. This is a different point from the first aspect.
  • the holder according to the third aspect can be used not only for holding the relay circuit, but also for joining the shielding plate and the housing together. Since the housing is made of rather inexpensive sheet steel, this holder made of resin is disposed between the heating coils and the shielding plate for achieving an electric insulation inexpensively between the housing and the heating coils
  • An induction heating cooker in accordance with a fourth aspect of the present disclosure includes a relay circuit that has a connecting section to receive the connection wire, and the holder includes an outer wall taller than the relays and the connecting section. This outer wall is disposed close to the housing. This is a different point from the third aspect.
  • This outer wall of the holder allows prolonging a creeping distance of insulation between the housing and the connecting section, so that the electric insulation can be more stable. If water entered around the shielding plate, the outer wall is able to protect the relay circuit from the water.
  • FIG. 1A is a perspective view of induction heating cooker 1 in accordance with the embodiment of the present disclosure.

  • Connection wire 27 is coupled to both the ends of each of heating coils 22 via round terminal 38 that is attached to the tip of wire 27 by heat-crimping. The resin coating has been removed from the tip of wire 27.
  • Heating coils 22 can be formed of materials other than copper, such as a wire formed of layers of copper and aluminum.
  • the shape of heating coil 22 is not limited to the oval shape, but it can be a round shape, a triangular shape, or a rectangular shape.
  • Heating-coil unit 6 can include three or less than three heating coils 22, or five or more than five heating coils 22.
  • FIG. 4 shows, two holders 26 are rigidly mounted with screws 34 to the rear side (underside) of shielding plate 24 around the edge thereof.
  • the rear side is opposite to the front side (top face) on which heating coils 22 are mounted.
  • Each one of holders 26 shapes like a box made of heat-resistant resin and having no lid (refer to FIG. 5 ).
  • One relay circuit 31 is rigidly mounted with screw 39 inside of each holder 26.
  • one relay circuit 31 works for two heating coils 22, so that induction heating cooker 1 includes two relay circuits 31, and two relays 32 are disposed in each of two relay circuits 31.
  • Relay circuit 31 includes one terminal pedestal 35a to be used for receiving power line 33 extended from drive circuit 9, and four terminal pedestals 35b to be used for receiving connection wires 27.
  • Terminal pedestals 35a and 35b work as connecting sections for connecting power line 33 and connection wires 27 to relay circuit 31 respectively.
  • Connection wire 27 is routed through opening 36 formed on shielding plate 24 and connects heating coil 22 disposed on the top face of shielding plate 24 to relay 32 disposed on the underside of shielding plate 24.
  • Relay 32 switches the connection in response to a signal supplied from drive circuit 9 via signal line 37. In response to this switching done by relay 32, the high-frequency electric power is fed to either one of two heating coils 22.

  • screw-slot 41 i.e. a stationary section
  • Holder 26 includes outer wall 40 taller than relay 32, terminal pedestals 35a, 35b with relay circuit 31 being disposed inside the holder 26. Rigid mounting of holder 26 to housing 10 causes outer wall 40 to approach housing 10.
