  As shown in FIG. 3, the first control board 43 and the sensors connection board 45 are communicably connected by a flat cable 63. Signal transmission of detection information of various sensors to the control means of the first control board 43 is performed via the flat cable 63.

  A first control board 43 equipped with control means, a second control board 44 communicably connected to the first control board 43 with the flat cable 61, and a communication with the first control board 43 and the flat cable 63 The connected sensors-type connection board 45 controls the heating cooker of the first embodiment of the present invention, and is a control unit of the first embodiment of the present invention.

  The connection form of the first control board 43 and the second control board 44 connected by the flat cable 61 will be described in detail with reference to FIG. FIG. 5 is a schematic view showing the operation of the heating cooker according to Embodiment 1 of the present invention and the state of the flat cable and the ferrite core as viewed from the direction of arrow A shown in FIG. 4 (FIG. 4) is there.

  The first control board 43 and the second control board 44 are provided side by side at the same height as shown in FIG. The flat cable 61 is connected at one end to a flat cable connection terminal 43 a provided at a position near the end of the first control substrate 43, and at the other end at a position near the end of the second control substrate 44. It is connected to the provided flat cable connection terminal 44a.

  A ferrite core 62 is attached to the flat cable 61. The ferrite core 62 is for reducing noise generated from the flat cable 61 and noise received from other components, for example, the left heating unit 5 and the right heating unit 6 which are induction heating units. Such noise causes the electronic parts and the like that receive the noise to generate heat, and causes problems in other devices.

  The ferrite core 62 has a rectangular parallelepiped shape and is provided with a hole through which the flat cable 61 can penetrate in the short direction, and the ferrite core 62 is attached to the hole by passing the flat cable 61 therethrough.

  The flat cable 61 is bent at a first bent portion 61a and a second bent portion 61b, as shown in FIG. 5, to form a Z shape. Although FIG. 5 shows the Z-shape viewed from the opposite side, the Z-shape is described here because it is a Z-shape when viewed from the opposite side of the state shown in FIG.

  The ferrite core 62 is attached between the first bent portion 61a and the second bent portion 61b. As described above, since the flat cable 61 is bent at the first bent portion 61a and the second bent portion 61b to form a Z shape, the movement of the ferrite core 62 is performed by the first bent portion 61a and the second bent portion. It is regulated by the bending portion 61b.

Therefore, since the ferrite core 62 does not move beyond the length between the bent portion 61a of the flat cable 61 and the second bent portion 61b, the mounting position can be held within a specific range without using a fixing member.

At this time, if the length between the bent portion 61a and the second bent portion 61b of the flat cable 61 is too long, the moving distance of the ferrite core 62 becomes long. Therefore, the bent portion 61a of the flat cable 61 and the second bent portion The length between the bent portions 61b is preferably longer than one length for the ferrite core 62 in a direction in which the flat cable 61 penetrates the ferrite core 62, and shorter than three lengths.

Further, even if the ferrite core 62 moves in the vertical direction due to vibration or the like, as shown in FIG. 5, the first bent portion 61 a is at a position where the ferrite core 62 is from the end of the second control substrate 44 to the inside of the substrate. And the second bent portion 61b, and contacts the second control board 44 earlier through the flat cable 61, so it does not move significantly in the vertical direction.

  Although not shown in FIG. 5, as shown in FIG. 6, for example, a sheet formed of an insulating polycarbonate material so as to sandwich the flat cable 61 and the ferrite core 62 with the second control board 44. By providing the cover 52, the movement of the ferrite core 62 in the vertical direction can be further reduced.

  Next, a connection form of the first control board 43 and the sensors connection board 45 connected by the flat cable 63 will be described in detail with reference to FIG. FIG. 7 is a schematic view showing the state of the flat cable and the ferrite core viewed from the direction of arrow B shown in the view (FIG. 3) of the operation of the heating cooker and the display unit according to Embodiment 1 of the present invention is there.

  As shown in FIG. 7, the first control board 43 and the sensor connection board 45 have a height from the back surface of the top plate 3 at the top from a length T from the back surface of the top plate 3 to the sensor connection board 45. The length T1 from the back surface of the plate 3 to the first control substrate 43 is shorter. That is, when viewed from the horizontal direction, the sensors connection substrate 45 and the first control substrate 43 are arranged at different heights, and the first control substrate 43 is higher than the sensors connection substrate 45. Provided in

  The flat cable 63 is connected at one end to a flat cable connection terminal 43b provided on the side facing the back surface of the top plate 3 at a position close to the end of the first control board 43, and the other end is a sensor It is connected to a flat cable connection terminal 45 a provided at a position close to the end of the class connection substrate 45.

  A ferrite core 62 is attached to the flat cable 63. The ferrite core 62 is for reducing noise generated from the flat cable 63 and noise received from other components, for example, the left heating unit 5 and the right heating unit 6 which are induction heating units. Such noise causes the electronic parts and the like that receive the noise to generate heat, and causes problems in other devices.

  The ferrite core 62 has a rectangular parallelepiped shape, and is provided with a hole through which the flat cable 63 can penetrate in the short direction, and the ferrite core 62 is attached to the hole by passing the flat cable 63 therethrough.

  The flat cable 63 has a bending portion 63a and a bending portion 63b connected to the bending portion 63a as shown in FIG. The other end of the bent portion 63a connected to the curved portion 63b is connected to the flat cable connection terminal 43b. The other end of the curved portion 63b connected to the bent portion 63a is connected to the flat cable connection terminal 45a.

  The ferrite core 62 is attached to the curved portion 63 b. The ferrite core 62 is in the form of a rectangular parallelepiped as described above, and the through holes extend in a straight line. By passing the curved portion 63b of the flat cable 63 into the straight through hole of the ferrite core 62, the curved shape becomes a resistance and the movement of the ferrite core 62 is restricted.

Therefore, since the ferrite core 62 has its curved portion 63b of the flat cable 63 acting as a resistance and its movement is restricted, the mounting position can be held within a specific range without using a fixing member.

However, the flat cable 63 may move in the vertical direction due to the vibration and the like. Therefore, the length T1 from the flat cable connection terminal 43b to the back surface of the top plate 3 is longer than the length L1 from the connection terminal 43b of the flat cable 63 to the bent portion 63a.

In this way, even if the flat cable 63 moves in the vertical direction due to vibration, the flat cable 63 and the ferrite core 62 do not contact the top plate 3, which may damage the back surface of the top plate 3 or the ferrite core 62. Can be prevented from being damaged.

In the first embodiment of the present invention, as shown in FIG. 7, one end of flat cable 63 is provided on the side facing the back surface of top plate 3 at a position close to the end of first control board 43. Although the flat cable connection terminal 43b is to be connected, it may be as shown in FIG.

FIG. 8 is a schematic view showing the flat cable and the ferrite core shown in FIG. 7 different from the flat cable and the ferrite core, and one end of the flat cable 64 is at the end of the first control board 43. A flat connected at a close position to a flat cable connection terminal 43c provided on the back side of the surface opposite to the back surface of the top plate 3 and having the other end near the end of the sensor connection substrate 45 It is connected to the cable connection terminal 45a.

  A ferrite core 62 is attached to the flat cable 64. The ferrite core 62 is for reducing noise generated from the flat cable 64 and noise received from other components, for example, the left heating unit 5 and the right heating unit 6 which are induction heating units. Such noise causes the electronic parts and the like that receive the noise to generate heat, and causes problems in other devices.

  The ferrite core 62 has a rectangular parallelepiped shape and is provided with a hole through which the flat cable 64 can penetrate in the short direction, and the ferrite core 62 is attached to the hole by passing the flat cable 64 therethrough.

  As shown in FIG. 8, the flat cable 64 has a bent portion 64a and a bent portion 64b connected to the bent portion 64a. The other end of the bent portion 64a connected to the curved portion 64b is connected to the flat cable connection terminal 43c. The other end of the curved portion 64b connected to the bent portion 64a is connected to the flat cable connection terminal 45a.

  The ferrite core 62 is attached to the curved portion 64b. The ferrite core 62 is in the form of a rectangular parallelepiped as described above, and the through holes extend in a straight line. By passing the curved portion 64b of the flat cable 64 into the straight through hole of the ferrite core 62, the curved shape becomes a resistance and the movement of the ferrite core 62 is restricted.

Therefore, since the ferrite core 62 has its curved portion 64b of the flat cable 64 acting as a resistance to restrict its movement, the mounting position can be held within a specific range without using a fixing member.

However, the flat cable 64 may move in the vertical direction due to the vibration and the like. Therefore, the length T2 from the surface opposite to the back surface of the top plate 3 of the first control board 43 to the back surface of the top plate 3 is longer than the length L2 from the connection terminal 43c of the flat cable 64 to the bent portion 64a. I am getting longer.

In this way, even if the flat cable 64 moves up and down due to vibration, the flat cable 64 and the ferrite core 62 will not contact the top plate 3, which may damage the back surface of the top plate 3 or the ferrite core 62. Can be prevented from being damaged.

In addition, since the flat cable connection terminal 43c for connecting the flat cable 64 is provided on the back surface side of the surface facing the back surface of the top plate 3, the flat cable 64 can be shortened and the cost of the flat cable 64 can be suppressed. .
