2. Description of the Related Art Conventionally, in a heating cooker, for example, there is one disclosed in Patent Document 1 as a touch input unit provided on a top plate. In Patent Document 1, a touch input unit is formed on the top surface of a top plate, and a detection electrode is formed below the top plate. In order to process the electrical signal (capacitance change) detected by the detection electrode, a detection circuit board is provided in a substantially horizontal state below the top plate, and a connection conductor plate is provided on the detection circuit board.

JP-A-2005-38739 (FIG. 7)

  In the above-mentioned Patent Document 1, since the detection electrode itself is configured to be directly connected to the connecting conductor plate, the position of the detection electrode, and thus the position of the touch input portion that forms a pair with the detection electrode, is determined by the conductor plate and the detection circuit. There is a problem that the arrangement position of the substrate is limited and the degree of freedom in the arrangement design of the touch input unit and the detection electrode is low. For example, in consideration of the operability and safety of the touch input unit, it is difficult to form a touch input unit and an electrode on the front end of the top plate that is easy to reach by fingers and far from the heating unit. It is a fact.

  As a countermeasure, a configuration is considered in which a detection electrode and an output unit that outputs an electrical signal detected by the detection electrode are connected by a wiring unit, and a detection circuit board or the like can be connected to the output unit. If it is this structure, it will become possible to set the installation position of a detection electrode as well as a touch input part, without being restrict | limited to the position of an output part. In other words, the degree of freedom in setting the position of the output unit is also increased.

However, in this case, when a human finger or the like approaches the output unit, an electric signal for detecting a human body is generated in this portion, and there is a possibility that a so-called touch input is erroneously detected.
The present invention has been made in view of the above-described circumstances, and it is an object of the present invention to provide a heating cooker in which the positions of the touch input unit and the detection electrode can be easily set and erroneous detection of touch input can be reliably prevented.

  The present invention is provided with a cooker body provided with a top plate in the opening on the top surface and a heating means below the top plate, and formed on the top surface of the top plate, for setting the heating conditions of the heating means, etc. The touch input unit is formed on the electrode substrate disposed below the top plate, and the detection electrode for detecting a human body contact with the touch input unit is electrically connected to the detection electrode through the wiring unit. The detection electrode is provided between the top plate and the electrode substrate, and is provided on the electrode substrate to output an electric signal detected by the detection electrode from the electrode substrate. It is characterized in that it is provided with a dielectric that is interposed in the form and forms a gap between the substrate-side output portion and the top plate.

  In the present invention, a detection electrode for detecting a human body contact with the touch input unit is formed on an electrode substrate disposed below the top plate, and an electric signal detected by the detection electrode is output from the electrode substrate. Since the board side output part is provided via the wiring part, the detection electrode can be formed at a position suitable for human body contact detection, and the board side output part is aligned with the position of the detection circuit board, etc. Can be provided. In addition, since a gap is formed between the substrate side output part and the top plate, it is possible to prevent erroneous detection of human contact. In addition, the gap is ensured by a configuration in which a dielectric is interposed between the top plate and the electrode substrate in a form covering the sensing electrode, so that a change in capacitance at the sensing electrode is reliably detected. It is possible to improve the accuracy of human body contact detection at the touch input unit.

  According to the present invention, it is easy to set the positions of the touch input unit, the detection electrode, and the substrate side output unit, and it is possible to reliably prevent erroneous detection of touch input.

Further, the wiring portions 27Bh corresponding to the plurality of detection electrodes 27B are similarly derived from the detection electrodes 27B at both ends as shown in FIG.

  The board side output portions 27Ae, 27Be, 28Ae-31Ae, 28Be-31Be of the wiring portions 27Ah, 27Bh, 28Ah-31Ah, 28Bh-31Bh are arranged at almost one place, and the connector 32 (see FIG. 1) Conductive connection is made to the terminals by soldering. In this case, this soldering is performed by placing so-called cream solder between the board-side output portions 27Ae, 27Be, 28Ae-31Ae, 28Be-31Be and the terminals of the connector 32 and heating them. Yes.

One end of a harness connector 35 is connected to the connector 34, and the other end of the harness connector 35 is connected to the main circuit board 11.

  Here, a plate-like dielectric 36 is interposed between the top plate 16 and the electrode substrate 26 so as to cover only the detection electrodes 27A, 27B, 28A to 31A, and 28B to 31B. . The dielectric 36 forms a gap G between the substrate side output portions 27Ae, 27Be, 28Ae to 31Ae, 28Be to 31Be and the top plate.

A plate-like insulator 37 is interposed between the electrode substrate 26 and the flange portion 15. Further, packings 29 and 30 are provided at the end of the flange portion 15.
In FIG. 7 showing a schematic electrical configuration relating to the induction heating coils 8 and 9, the configuration related to the detection electrodes 27A and 28A to 31A and the configuration related to the other detection electrodes 27B and 28B to 31B are basically the same. Since it is the same, I will explain the former. First, the control circuit 38 as control means is configured to include a microcomputer. The control circuit 38 is connected to inverter control circuits 39A and 39B, touch position detection circuits 40A and 40B, and operation detection circuits 51A to 54A and 51B to 54B. The inverter control circuits 39A and 39B control inverters 8I and 9I that supply high-frequency current to the induction heating coils 8 and 9, respectively.

  The touch position detection circuit 40A includes a plurality of detection electrodes 27A, an impedance circuit 41A, and heating intensity setting contact detection circuits 42 and 43. The impedance circuit 41A is configured by connecting a plurality of impedance elements 44 in series, and the plurality of detection electrodes 27A are connected to the impedance circuit 41A as shown in FIG. The oscillation output of the oscillation circuit 45 is given to both ends of the impedance circuit 41A via capacitors 46 and 47.

  The heating intensity setting contact detection circuits 42 and 43 are constituted by integrated circuits, which respectively process the outputs at both ends of the impedance circuit 41A, and have a diode 48, a resistor 49 and a charge capacitor 50. It is. The heating intensity setting contact detection circuits 42 and 43 detect a finger contact position with respect to the touch input unit 21A based on a capacitance change of any of the plurality of detection electrodes 27A, and a signal 42v corresponding to the finger contact position. , 43v are output to the control circuit 38.

  Corresponding to the detection electrodes 28A to 31A and 28B to 31B, operation detection circuits 51A to 54A and 51B to 54B shown in FIG. 1 are provided, respectively. Since these operation detection circuits 51A to 54A and 51B to 54B have basically the same configuration, the operation detection circuit 51A will be described as a representative.

  The operation detection circuit 51A includes a capacitor 55, the detection electrode 28A, and a selection contact detection circuit 56. The oscillation output of the oscillation circuit 45 is provided to the input terminal of the selection contact detection circuit 56 via the capacitor 55, the detection electrode 28A, the wiring portion 28Ah, and the connector 32. The selection contact detection circuit 56 has the same configuration as the heating intensity setting contact detection circuits 42 and 43, and is formed of an integrated circuit.

The output of the selection contact detection circuit 56 is given to the control circuit 38 via the harness connector 35.
The impedance circuit 44, the oscillation circuit 45, and the capacitors 46, 47, 55 of the touch position detection circuits 40A and 40B are mounted on the electrode substrate 26. The heating intensity setting contact detection circuits 42 and 43 and other contact detection circuits 56 are mounted on the detection circuit board 14.

  The operation of the above configuration will be described. For example, when the user wants to cook using the induction heating coil 8, his / her finger is brought into contact with the single touch input unit 22 </ b> A. Since the detection electrode 28A corresponding to the touch input unit 22A flows to the ground side through capacitive coupling by the human body, the selection touch detection circuit 56 of the operation detection circuit 51A corresponding to the single touch input unit 22A A contact detection signal (electric signal) is output and applied to the control circuit 38, and the control circuit 38 selects the induction heating coil 8.

  For example, when the user touches an appropriate part of the heating intensity setting touch input unit 21A in order to set the heating intensity, the detection electrode 27A corresponding to the contact part is connected via capacitive coupling by the human body. Since the current flows to the ground side, the impedance ratio of the impedance circuit 41A is different with the detection electrode 27A as a branch point, the ratio of the output signals 42v and 43v is different, and the control circuit 38 uses this ratio to contact the user's finger. The position, that is, the setting intensity of the heating intensity is determined. Then, the control circuit 38 turns on the light emitting diode 12 corresponding to the heating intensity set according to the determination result, and the induction heating coil 8 is switched via the inverter control circuit 39A and the inverter 8I according to the determination result. Control.

  According to the above-described embodiment, the detection electrodes 27A, 27B for detecting the human body contact with the touch input units 21A, 21B, 22A-25A, 22B-25B are applied to the electrode substrate 26 disposed below the top plate 16. 28A to 31A, 28B to 31B are formed, and wiring portions 27Ah, 27Bh, and 28Ah to 31Ah are used to output electrical signals detected by the detection electrodes 27A, 27B, 28A to 31A, and 28B to 31B from the electrode substrate 26. , 28Bh to 31Bh are provided with the substrate side output portions 27Ae, 27Be, 28Ae to 31Ae, and 28Be to 31Be, so that the detection electrodes 27A, 27B, 28A to 31A, and 28B to 31B are positions suitable for human body contact detection. The substrate side output portions 27Ae, 27Be, 28Ae to 31Ae, 2 Be~31Be can be provided in the combined position, etc. detecting circuit board 14. Moreover, since the gap G is formed between the substrate side output portions 27Ae, 27Be, 28Ae to 31Ae, 28Be to 31Be and the top plate 16, the user's fingers touch this portion A (see FIG. 1). Even if there is, there is very little change in the capacitance of the substrate side output portions 27Ae, 27Be, 28Ae to 31Ae, and 28Be to 31Be, and it is possible to prevent erroneous detection of human contact.

  In addition, the heat of the heated pan or the like is less likely to affect the board side output portions 27Ae, 27Be, 28Ae to 31Ae, and 28Be to 31Be, and the heat is prevented from affecting the soldering portion with the connector 32. it can. In addition, with respect to ensuring the gap G, the dielectric 36 is interposed between the top plate 16 and the electrode substrate 26 in a form that covers only the detection electrodes 27A, 27B, 28A to 31A, and 28B to 31B. Therefore, it is possible to reliably detect the capacitance change in the detection electrodes 27A, 27B, 28A to 31A, and 28B to 31B, and to detect the human contact with the touch input units 21A, 21B, 22A to 25A, and 22B to 25B. Accuracy can be improved. As a result, according to the present embodiment, the touch input units 21A, 21B, 22A to 25A, 22B to 25B, the detection electrodes 27A, 27B, 28A to 31A, 28B to 31B, and the board side output units 27Ae, 27Be, 28Ae to Position setting of 31Ae and 28Be to 31Be is easy, and erroneous detection can be reliably prevented.

  Further, according to the present embodiment, since the substrate side output portions 27Ae, 27Be, 28Ae to 31Ae, and 28Be to 31Be are provided on the lower surface of the electrode substrate 26, they are further separated from the top plate 16 and erroneous touch input is performed. The prevention of detection can be further ensured.

  Further, according to the present embodiment, the electrode substrate 26 is composed of a double-sided substrate, and the detection electrodes 27A, 27B, 28A to 31A, and 28B to 31B are formed on the upper surface of the electrode substrate 26, and the substrate side output portion 27Ae, 27Be, 28Ae to 31Ae, and 28Be to 31Be are provided on the lower surface of the electrode substrate 26, and wiring portions 27Ah, 27Bh, 28Ah to 31Ah, and 28Bh to 31Bh are provided with through holes (only the through hole 28Ah1 is shown in FIG. 1). Since the detection electrodes 27A, 27B, 28A to 31A, 28B to 31B and the substrate side output portions 27Ae, 27Be, 28Ae to 31Ae, and 28Be to 31Be are electrically connected, the detection electrodes 27A, 27B, and 28A on the upper surface of the electrode substrate 26 are provided. To 31A and 28B to 31B are output from the substrate side output portions 27Ae and 27 on the lower surface of the electrode substrate 26. e, 28Ae~31Ae, it is better to lead it to 28Be~31Be.

  Further, according to the present embodiment, the board-to-board type connector 32 is connected to the board side output portions 27Ae, 27Be, 28Ae to 31Ae, and 28Be to 31Be, and the detection electrodes 27A, 27B, and 28A to Since the detection circuit board 14 for receiving the electrical signals from 31A, 28B to 31B and detecting the presence or absence of human contact is configured to be connected in a substantially vertical state, the electronic components mounted on the detection circuit board 14 Heat effects can be reduced from pans. That is, if the detection circuit board 14 is provided in a horizontal state below the induction heating coils 8 and 9, the detection circuit board 14 is directly affected by the heat of a pan or the like, and there is a concern that the operation reliability may be lowered. However, this is not the case in this embodiment. In addition, a narrow space can be effectively used by positioning the detection circuit board 14 substantially vertically between the induction heating coils 8 and 9 and the touch input units 21A, 21B, 22A to 25A, and 22B to 25B. In particular, in this case, the detection circuit board 14 is provided between the heating intensity display units 20A and 20B (light emitting diode group 12) and the cooker body 3, so that the space can be used effectively.

  8 and 9 show a second embodiment of the present invention. In this embodiment, the following points are different from the first embodiment. That is, for example, a rectangular hole 61 is formed in a portion facing the detection electrodes 27A, 27B, 28A to 31A, and 28B to 31B in the flange portion 15, and the substantially cylindrical buffer member having elasticity in the vertical direction in the hole 61 portion. 62 and 62 are provided, and a pressing member 63 made of a metal plate for pressing the buffer member 62 from below to above is provided. In this case, the buffer member 62 is attached to the insulator 37, that is, indirectly attached to the electrode substrate 26.

  The buffer member 62 positions the electrode substrate 26 with respect to the cooker body 3. That is, the front and rear, right and left positioning of the electrode substrate 26 is performed by engaging the buffer member 62 with the diagonal corners of the hole 61 of the flange portion 15 of the cooker body 3. In this case, one buffer member 62 may be fitted to each hole 61. In this case, if the buffer member 62 is engaged with a different corner for each hole 61, the buffer member 62 is positioned in the front, rear, left, and right directions. it can.

  According to the second embodiment, since the holes 61 are formed in the portions corresponding to the detection electrodes 27A, 27B, 28A to 31A, and 28B to 31B in the flange portion 15 that is the top plate holding member, the detection electrodes 27A, 27B, The stray capacitance between 28A to 31A and 28B to 31B and the flange portion 15 can be reduced, and the contact detection accuracy can be improved. In addition, since the buffer member 62 having elasticity in the vertical direction is provided in the hole 61 portion and the pressing member 63 for pressing the buffer member 62 from below to above is provided, the dielectric between the electrode substrate 26 and the dielectric 36 is provided. There is no gap between the body 36 and the top plate 16, and the contact detection accuracy is further improved. Moreover, since the pressing member 63 is made of a metal plate, it is electrically stable regardless of whether the cabinet 1 is made of wood or metal (for example, stainless steel).

  Further, since the buffer member 62 is indirectly attached to the electrode substrate 26 via the insulator 37, the buffer member 62 can be attached to the conductor pattern of the electrode substrate 26 regardless of the formation position. The buffer member 62 may be directly attached to the electrode substrate 26 as long as the conductive pattern formation position is avoided.

  In addition, according to the present embodiment, since the electrode substrate 26 is positioned by the buffer member 62, it is not necessary to attach the electrode substrate 26 to the top plate 16 in advance at the time of manufacture, and the flange portion 15 of the cooker body 3 is attached. When the top plate 16 is bonded by bonding, the electrode substrate 26 can be positioned at an appropriate position, and assemblability can be improved.

  In addition, this invention is not limited to an above-described Example, It can implement by changing suitably. For example, the substrate side output portions 27Ae, 27Be, 28Ae to 31Ae, and 28Be to 31Be are formed on the upper surface of the same electrode substrate 26 as the detection electrodes 27A, 27B, 28A to 31A, and 28B to 31B, and the substrate side output portions 27Ae and 27Be are formed. , 28Ae-31Ae, 28Be-31Be may be appropriately connected to a connection terminal or the like. In this case as well, the gap G can prevent erroneous detection of touch input, and conductive connection is performed by soldering. Can reduce the thermal effect on the solder portion. Moreover, the board | substrate side output part 27Ae, 27Be, 28Ae-31Ae, and 28Be-31Be do not need to be provided collectively in one place.
