Description

  The present invention relates to a gas stove.

  Conventionally provided gas stoves include a configuration in which a part of a plate constituting the outer surface portion of the stove is made detachable for reasons such as facilitating construction and maintenance. For example, Patent Document 1 discloses an example in which a top plate is detachable in a stove including a main body case whose upper open portion is covered with a top plate.

Japanese Patent Laid-Open No. 2004-251589

  By the way, when a part of the outer surface portion of the gas stove is an assembly plate that can be attached to and detached from the main body, it may be possible to attach an electronic component to the assembly plate. For example, as an example of the assembly plate, there is a top plate attached so as to cover the upper part of the main body, and it is assumed that the function of the top plate is enhanced by providing electronic components on the top plate. However, when an electronic component is provided on such an assembly plate, an electric wire for securing an electrical connection between the electronic component and the electronic circuit on the main body side is necessary. Must be interposed between the main body and the main body.

  However, simply providing an electric wire for connecting the assembly plate and the main body will leave the assembly plate and the main body connected by the electric wire when the assembly plate is removed from the main body. For this reason, it is desirable to provide a connector for separating the electric wire (a connector for dividing the circuit on the assembly plate side and the circuit on the main body side) in the middle of the electric wire. In this way, when removing the assembly plate from the main body during construction or maintenance, the connector can be disconnected and the circuit on the assembly plate side can be separated from the circuit on the main body side. It is possible to work with the attached plate completely removed from the main body.

  However, when the assembly plate side circuit can be separated from the main body side circuit by releasing the connector in this way, the assembly plate is completely removed from the main body portion and then reattached. In addition, the operator may forget to connect the connectors. In this way, if the assembly plate is attached to the main body while the connector connection is forgotten, there is a risk that the device will be used without the electronic components on the assembly plate side operating normally. For example, in a configuration in which the gas burner can be ignited even if the connector is not connected, even if the operator forgets to connect the connector and finishes the assembly work of the assembly plate, the ignition itself is possible. . In such a configuration, even if the connector is not connected, if the operator can confirm the ignition by an ignition confirmation operation or the like, the operator may misunderstand that the device has returned to the normal state. After that, there is a possibility that the connector is used as usual without doubting that the connector is not connected.

  The present invention has been made to solve the above-described problems, and an assembly plate that forms a part of the outer surface of the device can be attached to and detached from the main body, and an electronic component is provided on the assembly plate side. It is a structure and it aims at providing the structure which can prevent the situation where an apparatus is normally used in the state which the electronic component by the side of an assembly board does not operate | move normally.

The gas stove of the first invention is
The stove body,
An assembly plate assembled to the stove body, at least part of which constitutes the outer surface of the device;
A control unit that controls the gas burner; a first wiring unit that includes a plurality of wires; and a first connector unit that is connected to the first wiring unit; ,
The electronic component attached to the assembly board, a second wiring part composed of a plurality of wires, and a second connector part connected to the second wiring part, and second assembled to the assembly board side A circuit component;
A power supply,
With
When the first connector part and the second connector part are coupled, power is supplied from the power supply part to the first circuit constituent part, and the first circuit constituent part and the second circuit are supplied. The component is at least partially conductive,
When the first connector part and the second connector part are not coupled, power is not supplied from the power supply part to the first circuit constituent part, and the first circuit constituent part and the second circuit part are not supplied. The circuit configuration unit is in a non-conductive state.

  In the first invention, an assembly plate forming a part of the outer surface of the device is detachable from the stove body, and a second circuit configuration unit including an electronic component is provided on the assembly plate side. Then, power is supplied from the power supply unit to the first circuit configuration unit on the condition that electrical connection between the first circuit configuration unit and the second circuit configuration unit is ensured, and the first circuit configuration unit and the second circuit configuration unit When electrical connection with the circuit component is not ensured, power is not supplied from the power supply unit to the first circuit component. That is, even if the first connector part and the second connector part are not coupled and the assembly plate is assembled to the stove body while the second circuit component is electrically separated from the stove body side, In this case, the first circuit component does not operate.

  Therefore, it is possible to prevent a situation where the device is used as usual while the electronic component on the assembly plate side does not operate normally. Even if the assembly plate is assembled without the connector being connected, the user can surely grasp the state by the non-operation of the first circuit component, and can easily take appropriate measures.

The gas stove of the second invention is
The stove body,
An assembly plate assembled to the stove body, at least part of which constitutes the outer surface of the device;
A control unit that controls the gas burner; a first wiring unit that includes a plurality of wires; and a first connector unit that is connected to the first wiring unit; ,
The electronic component attached to the assembly board, a second wiring part composed of a plurality of wires, and a second connector part connected to the second wiring part, and second assembled to the assembly board side A circuit component;
A power supply,
A detection unit for detecting that the first connector unit and the second connector unit are coupled;
With
The control unit operates the gas burner on the condition that the detection unit detects the coupling between the first connector unit and the second connector unit,
When the detection unit does not detect the coupling between the first connector unit and the second connector unit, the control unit does not operate the gas burner.

  In the second aspect of the invention, an assembly plate that forms a part of the outer surface of the device can be attached to and detached from the stove body, and a second circuit component having an electronic component is provided on the assembly plate side. And the detection part which detects that the 1st connector part and the 2nd connector part are couple | bonding is provided, and when a detection part detects the coupling | bonding of a 1st connector part and a 2nd connector part, a control part is When the gas burner is operated and the connection between the first connector portion and the second connector portion is not detected, the control portion does not operate the gas burner. That is, even if the first connector part and the second connector part are not coupled and the assembly plate is assembled to the stove body while the second circuit component is electrically separated from the stove body side, Will cause the gas burner to not work properly.

  Therefore, it is possible to prevent a situation where the device is used as usual while the electronic component on the assembly plate side does not operate normally. Even if the assembly plate is assembled without the connector being connected, the user can surely grasp the state by the non-operation of the gas burner, and can easily take an appropriate measure.

  In both the first and second inventions, the assembly plate may be a top plate that is assembled to the stove body from above. And the structure containing the top-plate side board | substrate assembled | attached to the back surface side of a top plate may be sufficient.

  According to this structure, the gas stove which made the top plate with which the electronic component was assembled | attached made removable. And when removing the top plate from the stove body, it is possible to release the top plate and the electronic components from the stove body in a form that eliminates the restriction due to the wires by releasing the connection of the connector, thus improving workability. be able to. On the other hand, even if the connection of the connector is forgotten when the top plate is mounted and the top plate is assembled without the electronic components provided on the top plate being operated, in this case, the first circuit component is operated. Therefore, it is possible to prevent the device from being used normally.

  In both the first and second inventions, the electronic component may include an operation unit that receives an operation from the outside. And when the 1st connector part and the 2nd connector part are combined, when the operation part is operated, it will be in the state where a predetermined operation signal is inputted into the 1st circuit composition part, and the 1st connector part When the second connector portion is not coupled to the second connector portion, a signal from the operation portion side may not be input to the first circuit configuration portion.

  According to this configuration, the operation unit can be provided on the assembly plate that is attached to and detached from the stove body, and when the assembly plate is removed from the stove body, the connector is released so that there is no restriction due to the electric wire. In this way, the assembly plate and the operation part can be detached from the stove body. On the other hand, even if the assembly plate is assembled to the stove body while the connectors are not connected to each other and the signal from the operation unit is not input to the first circuit component, Can be prevented from operating. Therefore, it is possible to prevent a situation in which the device is used as usual in a state where the operation unit provided on the assembly plate does not operate normally.

  In both the first and second inventions, the power supply unit may be provided in the stove body, and the power supply side wiring connected to either the high potential side terminal or the low potential side terminal of the power supply unit You may be connected to the 1st connector part as a part of 1 wiring part. Then, the wiring that becomes the reference conductive path on the high potential side or the low potential side in the first circuit component is connected to the first connector part as a part of the first wiring part, and the wiring that becomes the power supply side wiring and the reference conductive path An intermediate wiring for conducting the connection may be connected to the second connector part as a part of the second wiring part. And when the 1st connector part and the 2nd connector part have combined, the power supply side wiring and the wiring used as a standard conductive path will be in a conduction state via an intermediate wiring, and the 1st connector part and the 2nd connector When the part is not coupled, the power supply side wiring and the wiring that becomes the reference conductive path may be in a non-conductive state.

  In this configuration, when the first connector part and the second connector part are coupled, the path from the terminal of the power supply part to the reference conductive path becomes conductive through the intermediate wiring, and the first circuit is connected from the power supply part to the first circuit. Electric power can be supplied to the components. On the other hand, when the first connector portion and the second connector portion are not coupled, the intermediate wiring is not interposed in the route that continues from the terminal of the power supply portion to the reference conductive path, and this route becomes non-conductive. Therefore, during such disconnection, the power supply from the power supply unit to the first circuit component unit can be reliably shut off, and the device can be used as usual while the electronic components on the assembly plate side do not operate normally. The situation where it is done can be prevented more reliably.

The microcomputer 50 corresponds to an example of a control unit that controls the gas burners 5 and 6.

Next, an electrical connection structure between the top plate 2 side and the stove body 4 side will be described.
In the gas stove 1 shown in FIGS. 1 and 2, the first circuit configuration unit 61 is assembled to the stove body 4, and the second circuit configuration unit 62 is assembled to the top plate 2.

  As shown in FIGS. 3 and 4, the first circuit configuration unit 61 includes a first wiring unit 71 composed of a plurality of wirings, and a first connector unit 81 connected to the first wiring unit 71. It is configured as an electronic circuit assembled on the main body 4 side. The first circuit configuration unit 61 is a portion that is continuously mounted as a component on the stove body 4 side after the top plate 2 and the second circuit configuration unit 62 are removed from the stove body 4.

  The second circuit configuration unit 62 includes an operation board 90 and an operation switch 91 as electronic components attached to the top plate 2, a second wiring unit 72 composed of a plurality of wires, and a second wiring unit 72 connected to the second wiring unit 72. 2 connector portion 82. The operation board 90 corresponds to an example of a top board. The second circuit configuration unit 62 is configured as an electronic circuit assembled on the top plate 2 side, and is removed together with the top plate 2 as a coupling body assembled to the top plate 2 when the top plate 2 is removed from the stove body 4. Part.

  In this configuration, as shown in FIGS. 3 and 4A, when the first connector portion 81 and the second connector portion 82 are connected in a regular connection state, the first circuit configuration portion 61 is connected from the power supply portion 40. Can be energized, and power is supplied from the power supply unit 40 to the first circuit configuration unit 61. And when the 1st connector part 81 and the 2nd connector part 82 are connected in the regular connection state in this way, the 1st circuit structure part 61 and the 2nd circuit structure part 62 have conducted at least partially. It becomes a state. In this state, for example, a signal can be transmitted from the top plate 2 side to the stove body 4 side using signal lines 72D and 71D described later. On the other hand, as shown in FIG. 4B, when the first connector portion 81 and the second connector portion 82 are not coupled, power is not supplied from the power supply portion 40 to the first circuit configuration portion 61. In addition, the first circuit configuration unit 61 and the second circuit configuration unit 62 are turned off.

Here, a configuration for switching between the power supply state and the power cut-off state will be described in detail.
In this configuration, the power supply unit 40 is provided in the stove main body 4 and the first circuit configuration unit 61 is also provided in the stove main body 4. However, the power supply path from the power supply unit 40 is on the second connector unit 82 side. It is the composition which goes through. For this reason, if the 2nd connector part 82 is removed with the top plate 2, an electric power supply path | route will be interrupted | blocked.

  Specifically, as shown in FIG. 4, the power supply side wiring 71 </ b> A connected to the low potential side terminal (minus terminal) of the power supply unit 40 is connected to the first connector unit 81 as a part of the first wiring unit 71. ing. Further, the wiring 71 </ b> B serving as a low-potential-side reference conductive path in the first circuit configuration unit 61 is connected to the first connector unit 81 as a part of the first wiring unit 71. On the other hand, on the second connector portion 82 side, an intermediate wiring 72A for connecting the power supply side wiring 71A and the wiring 71B serving as a reference conductive path is connected as a part of the second wiring portion 72. The wiring 71B is a wiring that is kept at the ground potential when the gas stove 1 is used and is used as the ground.

  In this configuration, as shown in FIGS. 3 and 4A, when the first connector portion 81 and the second connector portion 82 are connected in a regular connection state, the power supply side wiring 71A and the reference conductive path are connected. The wiring 71B to be in a conductive state through the intermediate wiring 72A. As a result, the wiring 71B serving as the reference conductive path is electrically connected to the low potential side terminal (minus terminal) of the power supply unit 40 and the ground line, and is maintained at the ground level. Accordingly, the power supply circuit 41 shown in FIG. 3 includes a power supply line (conductive path by the wiring 74) to which a predetermined DC voltage is applied, and a ground line (conductive path by the wirings 71A and 71B) maintained at the ground potential. Is ensured, power is supplied from the power supply unit 40, and driving power is supplied.

  Moreover, in this structure, the operation switch 91 which receives operation from the outside as an example of the electronic component assembled | attached to the top plate 2 (assembly board) is provided. The operation switch 91 is configured as a switch that generates a predetermined pressing signal when a pressing operation is performed from the outside. As shown in FIGS. 3 and 4A, when the first connector portion 81 and the second connector portion 82 are connected in a regular connection state, the signal line 72D (operation switch 91 on the top plate 2 side) is connected. When the operation switch 91 is pressed in such a conductive state, the signal line 71D on the stove main body 4 side is in a conductive state, and a predetermined operation is performed via the signal lines 72D and 71D. The pressing signal (for example, H level signal) is input to the switch input circuit 42.

  On the other hand, as shown in FIGS. 4B and 5, when the first connector portion 81 and the second connector portion 82 are not connected, the signal lines 72D and 71D are insulated from each other. That is, even if the operation switch 91 is pressed, no signal transmission is performed via the signal lines 72D and 71D, and no pressing signal is input to the first circuit configuration unit 61.

  However, when the operation switch 91 becomes unusable in this way, the power supply to the first circuit configuration unit 61 is also cut off, so that the device should not be used when the operation switch 91 is unusable. it can. Specifically, as shown in FIGS. 4B and 5, when the first connector portion 81 and the second connector portion 82 are not connected, the power supply side wiring 71 </ b> A and the wiring 71 </ b> B serving as the reference conductive path are Insulated and non-conductive. In this case, the wiring 71B to be the reference conductive path on the first circuit configuration unit 61 side is not connected to the low potential side terminal (minus terminal) of the power supply unit 40 and the ground, and the end of the wiring 71B is open. Become. In this case, the power supply circuit 41 is not conducted to the ground, and the power supply from the power supply unit 40 is cut off.

  Although the use of the operation switch 91 is not particularly limited, for example, it can be suitably used as a release switch for permitting high temperature. In this case, the microcomputer 50 functions as means for switching between the normal mode and the high-temperature stir-fry mode, and sets the gas stove 1 to the normal mode during a period when the conditions for the high-temperature fry mode are not satisfied. In the normal mode, the microcomputer 50 detects the detected temperature when the temperature detected by one of the thermistors 7 and 8 becomes a predetermined first threshold temperature (for example, 250 ° C.) when the gas burner 5 or the gas burner 6 is used. The protection operation is performed so that the thermistor side gas burner that has reached the threshold temperature is automatically digested.

  On the other hand, a period from when the operation switch 91 is pressed until a predetermined end condition is satisfied (for example, until a predetermined time elapses after the operation switch 91 is pressed) can be set as a “period for satisfying the high-temperature frying mode”. When the operation switch 91 is pressed, the microcomputer 50 shifts the threshold temperature from the first threshold temperature to a higher second threshold temperature (for example, 290 ° C.) during this period. In the high temperature frying mode, the microcomputer 50 detects the detected temperature when the temperature detected by either the thermistor 7 or 8 becomes the second threshold temperature (for example, 290 ° C.) when the gas burner 5 or the gas burner 6 is used. The protection operation is performed so that the thermistor-side gas burner that has reached the threshold temperature is automatically digested.

  When the operation switch 91 is used for such a purpose, the top plate 2 is attached to the stove body in a state where the first connector portion 81 and the second connector portion 82 are not connected as shown in FIGS. 4, even if the operation switch 91 is pressed, no signal is transmitted via the signal lines 72 </ b> D and 71 </ b> D, resulting in an abnormal device state that cannot be set to the high-temperature frying mode. . However, in this case, since the power supply to the first circuit component 61 side is also cut off and the operation of the device (ignition operation, etc.) is also stopped, the device seems to be used in an abnormal device state that cannot be set to the high temperature frying mode. There is nothing wrong.

<Example 2>
Next, the gas stove 1 of Example 2 is demonstrated with reference to FIG.
In the gas stove 1 of the second embodiment, the configuration of the stove body 4 and the configuration of the top plate 2 are the same as those of the first embodiment, and are configured as shown in FIGS. Further, the first circuit configuration unit 61 includes a power supply side wiring 71A and a wiring 71B serving as a reference conductive path which are not connected to the first connector unit 81 in the first embodiment. Unlike the circuit configuration unit 61, the rest is the same as the first circuit configuration unit 61. The second circuit configuration unit 62 is the same as the second circuit configuration unit 62 of Example 1 except that the intermediate wiring 72A is omitted. In FIG. 6, the first wiring part 71 other than the signal line 71D is omitted, and the second wiring part 72 other than the signal line 72D is omitted.

  The electrical configuration of the gas stove 1 according to the second embodiment is that the sensor 210 and the sensor input circuit 212 are provided in addition to the points where the first circuit configuration unit 61 and the second circuit configuration unit 62 are changed as described above. 1 is the same as the configuration of FIG.

  The gas stove shown in FIG. 6 is provided with a sensor 210 that detects that the first connector portion 81 and the second connector portion 82 are coupled. The sensor 210 corresponds to an example of a detection unit. The sensor 210 may be any sensor that can detect the coupling between the first connector portion 81 and the second connector portion 82. For example, the sensor 210 detects contact of the second connector portion 82 provided on the first connector portion 81. A pressure sensor that detects the approach of the second connector portion 82 may be used. Alternatively, other sensors may be used.

  In this configuration, when the sensor 210 (detection unit) detects the coupling between the first connector unit 81 and the second connector unit 82, the microcomputer 50 operates the gas burner. That is, the microcomputer 50 outputs a detection signal in which the sensor 210 detects the coupling between the first connector portion 81 and the second connector portion 82 when any of the ignition switches 21 and 22 described above is ignited. On the condition that the detection signal is detected via the sensor input circuit 212, the gas burner corresponding to the operated switch of the gas burners 5 and 6 is ignited. Conversely, when the sensor 210 (detection unit) does not detect the coupling between the first connector unit 81 and the second connector unit 82, even if an ignition operation is performed on either of the ignition switches 21 and 22, The gas burner corresponding to the switch is not ignited.

  Even with such a configuration, it is possible to prevent a situation in which the device is used as usual while the electronic component on the top plate 2 side does not operate normally. Even if the top plate 2 is assembled without the connector being connected, the user can surely grasp the state by the non-operation of the gas burner, and can easily take appropriate measures.
