FIG. 4 is a block diagram of a gas flow rate control portion of the built-in gas stove.

  1 to 4, a stove main body 11 which is a device main body is configured by a case 12 formed in a box shape, and an upper portion is covered with a top plate 13. The stove main body 11 is dropped into the opening 14a of the kitchen counter 14 and incorporated, and the top plate 13 is placed with its outer peripheral edge placed on the upper surface of the peripheral edge of the opening 14a.

  The burner 15 that uses gas as fuel is partly located in the case 12 so that it does not protrude above the top plate 13, and is located between the left and right sides of the front side of the top plate 13 and in the middle between the left and right sides. Three pieces arranged respectively on the rear side are provided. Each of the three burners 15 is provided with a gas flow rate control device 16, through which the gas is supplied and shut off, and the thermal power is adjusted by controlling the gas flow rate. Therefore, in FIG. 4, a gas flow rate control part for supplying gas to one burner 15 will be described as an example.

  The gas flow rate control device 16 moves to the left and right against the gas flow rate control plate 17, and adjusts the flow rate of the gas passing through the change in the opening area that matches the gas flow rate control plate 17, and supplies and shuts off the gas. The slide closure 18 to be performed, the stepping motor 19 as a motor for operating the slide closure 18, and the rotation of the stepping motor 19 are converted into left and right movements and rotated by the battery power source 20 of two single dry batteries. A driving force conversion means 21 such as a cam or a gear that can be increased so that the slide closure 18 can be sufficiently moved even by the rotational force of the stepping motor 19 and an encoder 22 that always detects the position of the slide closure 18 by the stepping motor 19. It is comprised and it provides in the position which is easy to supply the gas to the burner 15 in case 12. FIG.

  The control means 23 is composed of a microcomputer and its peripheral circuits, is configured separately from the gas flow rate control device 16 and is provided in the case 12, connected to the battery power source 20 to obtain power, and the burner 15 ON / OFF. In order to instruct the heating power adjustment, the stepping motor 19 and the encoder 22 of the gas flow rate control device 16 are connected via a belt-like flat cable 24.

  The operation unit 25 is an electric contact type switch, adopts a tact switch, a capacitance switch, etc., is configured to be a soft touch type that operates even when touched lightly, and is provided corresponding to each of the three burners 15. Thus, the gas flow rate control device 16 and the control means 23 are formed separately. In other words, the operation unit 25 can be formed separately from the gas flow rate control device 16 and the control means 23. The operation unit 25 is operated by the stepping motor 19 that uses the battery power source 20 as a power source and rotates by a pulse signal. Since the slide closure 18, the gas flow rate control plate 17, and the encoder 20 are configured and operated according to the control instruction of the control means 23, the operation unit 25 is electrically connected to the control means 23 by the flat cable 24. It becomes possible to send ON / OFF of the burner 15 and a signal for adjusting the thermal power.

  Therefore, the operation unit 25 is independent of the installation position of the gas flow rate control device 16 and the control means 23, and only the thermal effect, operability, and visibility due to the flame of the burner 15 are considered, One of the peripheral portions on the top surface of the top plate 13 that is less thermally affected by the burner 15 that can be installed in terms of temperature, is provided on the peripheral front portion 13a on the near side, and is connected to the control means 23 via a flat cable 24. When the finger of the user's hand is touched, a signal for ON / OFF of the burner 15 and heating power adjustment is sent to the control means 23.

  Further, the operation unit 25 is slightly raised from the upper surface of the top plate 13, covered with a horizontally long operation unit installation unit 26 that is substantially flush with the top plate 13, and is provided flush with the upper surface of the operation unit installation unit 26. This is composed of an ignition / extinguishing operation part 25a of the burner 15 and right and left heating power adjustment operating parts 25b for raising and lowering the heating power, and in addition to this, it is added when a function is added to the gas stove It is.

  The display unit 27 is arranged in parallel with the operation unit installation unit 26 so that it can display five levels of thermal power adjustment and ignition extinguishment in the vicinity of the thermal power adjustment operation unit 25b which is the operation unit 25. It is connected to the control means 23 via the flat cable 24 so that it can be turned on and off in conjunction with the user's finger touching the ignition / extinguishing operation unit 25a and the thermal power adjustment operation unit 25b.

  The heat shield wall 28 as a heat shield means is formed in a substantially U shape having a path through which air flows in a hollow state, and the top plate 13 is interposed between the burner 15, the operation unit 25, and the display unit 27. It protrudes from the upper surface and is provided in a horizontally long shape to protect the operation unit 25 and the display unit 27 from being heated by the flame of the burner 15 to reduce the thermal influence. And since the burner 15 has low height (part protruding from the top plate 13), the height of the heat shield wall 28 is set as low as possible.

  The heat shield wall 28 is provided with a plurality of vent holes 29 and 30 on the surface facing the burner 15 and the inner bottom surface of the heat shield wall 28. Therefore, when the burner 15 is combusting, the temperature inside the case 12 as the stove main body 11 also rises slightly, so that the air for secondary combustion flows through the air holes 29 and the heat shield walls 28 as indicated by arrows. Is used to burn the burner 15 through the air holes 30 and the air holes 30, and when the burner 15 is extinguished, air flows in the direction opposite to the arrow to quickly discharge the air whose temperature has risen slightly in the case 12. In any state, air flows in the path of the internal space of the heat shield wall 28, which can contribute to the heat shield action.

  The back guard 31 has a front inclined surface 31a in which the rear peripheral portion of the top plate 13 is gradually inclined slightly upward, and a rear inclined surface 31b that suddenly descends from the top of the front inclined surface. A plurality of air holes 32 are formed in 31b, and the same effect as the air holes 29 and 30 of the heat shield wall 28, that is, the inflow of secondary combustion air into the case 12, and the inside of the case 12 The structure is expected to discharge the air whose temperature has risen.

  The temperature detector 33 is arranged in the heat shield wall 28 to detect the temperature in the vicinity of the operation unit 25 as shown in FIG. 2, and is located in the path in the heat shield wall 28 as shown in FIG. In order to detect the temperature of the air flowing therethrough and to detect the degree of heat influence from the flame of the burner 15 by radiant heat and heat conduction, the metal element cover 33a covering the element is provided on the metal heat shield wall 28. Installed directly. Thus, the temperature detector 33 that detects the temperature in the vicinity of the operation unit 25 with the configuration provided in the heat shield wall 28 outputs a control signal to the gas flow rate control device 16 of the burner 15. It connects so that it may be taken in by the thermal-power change control means 23a provided in the control means 23 to perform.

  When the temperature detector 33 detects a predetermined temperature which is not preferable due to the thermal influence from the flame of the burner 15 and the detection signal is received, the heating power change control means 23a is configured to change the heating power of the burner 15. When the gas flow rate is reduced by controlling the flow rate control device 16 and subsequently the temperature signal detected by the temperature detector 33 gradually increases, the gas flow rate control device 16 is controlled accordingly. The gas supply amount is gradually reduced to reduce the heating power of the burner 15, and when the temperature signal detected by the temperature detector 33 reaches a predetermined upper limit temperature, the gas flow control device 16 is controlled to stop the gas supply amount. And a control flow for executing a control sequence for extinguishing the burner 15.

  Further, the heating power change control means 23a controls the display unit 27 so that when the temperature detector 33 detects a predetermined temperature as described above, a display different from the normal operation of the gas stove is displayed. For example, if five LEDs of the display unit 27 indicating the thermal power state in use are lit, when the temperature detector 33 detects a predetermined temperature, display control for blinking the five LEDs and the temperature detector The temperature signal detected by 33 gradually increases, and in response to this, the gas flow rate control device 16 is controlled to gradually reduce the gas supply amount to reduce the heating power of the burner 15. If three LEDs are lit, there is also a control flow for executing a control sequence for performing display control according to the thermal power adjustment state of the thermal power change control means 23a by blinking the three LEDs.

  The ignition / extinguishing operation unit 25a, the thermal power adjustment operation unit 25b, and the display unit 27, which are the operation unit 25 provided in the operation unit installation unit 26 that is a part of the top board 13, are covered with a resin membrane. The ignition / extinguishing operation unit 25a and the thermal power adjustment operation unit 25b are configured by installing a board (not shown) on which a tact switch is mounted at the lower part, and one end of a flat cable 24 is connected to the board, and the other end Is connected to the control means 23 of the gas flow rate control device 16. In the figure, 34 is a goto, 35 is a burner protrusion opening provided on the top plate 13, 36 is a former solenoid valve connected by piping before the gas flow control device 16, and the stepping motor 19 and encoder 22 are broken or flat. The gas supply is shut off when the cable 24 is not controllable due to the occurrence of disconnection or the like, or the power supply being stopped. Reference numeral 37 denotes a power supply operation unit, which is one of the operation units 25 provided with the same configuration as the operation unit 25, and is a power switch that turns the battery power supply 20 on and off in order to ensure the safety of use of the gas stove. Reference numeral 38 denotes discharge ignition means for igniting gas ejected from the burner 15 by discharge.

  The operation and action of the built-in gas stove configured as described above will be described below. When the user lightly presses the power operation unit 37, the battery power source 20 is supplied to the control means 23. Subsequently, when the ignition / extinguishing operation section 25a of the operation section 25 is pressed, an ignition signal is sent to the control means 23 via the flat cable 24, and one of the display sections 27 is turned on by the control means 23 and discharge ignition is performed. Means 38 begins to discharge.

  Further, the stepping motor 19 of the gas flow rate control device 16 to which the signal has been transmitted via the flat cable 24 is driven, the slide closing 18 is moved, the gas is supplied to the burner 15, and the discharge ignition means 38 that has started discharging. It is ignited and a flame is formed in the burner 15.

  When the user presses one of the left and right heating power adjustment operation units 25b, the number of lighting of the display unit 27 is increased or decreased depending on the number of times the user presses. The current position signal of the stepping motor 19 corresponding to the position of the slide closing 18 is taken in, the value for sliding the slide closing 18 is calculated, and a pulse signal is sent to the stepping motor 19.

  Then, the gas flow rate control device 16 is operated by the stepping motor 19 to control the gas flow rate so that the set value of the thermal power adjustment operation unit 25b is set, and the combustion amount of the burner is controlled to adjust the thermal power. Further, when the burner 15 is extinguished, the control means 23 to which the extinguishing signal is transmitted by pressing the ignition / extinguishing operation unit 25a again drives the stepping motor 19 to close the slide closing 18 and also displays the display unit 27. Will also turn off.

  As described above, in the present embodiment, the gas flow rate control device 16 and the control means 23 for adjusting the thermal power by controlling the gas supply and shutoff and the gas flow rate to the burner 15 are installed in the case 12 of the stove body 11. The operation unit 25 can be installed separately without being influenced by the installation position of the gas flow rate control device 16 and its control means 23, so that only the heat effect, operability, and visibility due to the flame of the burner 15 are taken into consideration. It is possible to dispose on the peripheral front portion 13a, which is one of the peripheral portions on the top surface of the top plate 13, where the thermal effect of the flame of the burner 15 that can be installed on temperature 13 is small.

  Therefore, the user can operate the operation unit 25 from the upper side while looking at the operation unit 25 from above with the posture standing in front of the top plate 13 of the gas stove at the kitchen counter 14, greatly improving operability and visibility. Can be improved. The display unit 27 also displays the operating state of the stove main body 11 in the vicinity of the operation unit 25 in conjunction with the operation of the operation unit 25. Therefore, the operation unit 25 can be operated while viewing the display unit 27 in a standing posture. And operability can be further improved.

  When the temperature detector 33 that detects the temperature in the vicinity of the operation unit 25 detects a predetermined temperature that affects the operation unit 25, the heating power change control unit 23a of the control unit 23 that has captured this signal Since the control device 16 is controlled to reduce the heating power of the burner 15, it is possible to automatically avoid the thermal effect due to the flame of the burner and improve safety and reliability. Further, when the temperature detected by the temperature detector 33 gradually increases, the heating power change control means 23a controls the gas flow rate control device 16 according to this and adjusts the heating power of the burner 15 to gradually decrease it. However, when the temperature detected by the temperature detector 33 becomes high and finally reaches a predetermined upper limit temperature, the gas flow rate control device 16 is controlled to extinguish the burner 15, so that the degree of the thermal effect of the burner flame is increased. By adjusting the heating power, it is possible to ensure avoidance operation that balances the influence on cooking and safety and reliability.

  The heating power change control means 23a of the control means 23 is such that when the temperature detector 33 detects a predetermined temperature in the vicinity of the operation section 25, the gas stove is used in normal operation, and five LEDs on the display section 27 are lit. The display control for blinking these five can be performed to accurately notify that the gas stove is operating differently from the normal operation, and the user can be urged to return to the normal use mode.

  Further, the heating power change control means 23a of the control means 23 further gradually increases the predetermined temperature signal detected by the temperature detector 33 that detects the temperature in the vicinity of the operation unit 25 as described above. In response to this, the gas flow control device 16 is controlled to not only reduce the thermal power of the burner 15, but also this thermal power control state is reduced by the LED of the display unit 27 being reduced by the thermal power control and being lit. As shown above, it is possible to notify the state where the gas stove was operating differently from the normal operation by flashing five as described above, expanding the selection range of the avoidance operation for the user, and improving usability Improvement can be achieved.

  Also, the burner is provided by a substantially U-shaped heat shield wall 28 which is installed on the top plate between the operation unit 25 and the burner 15 in the vicinity of the operation unit 25 and has a path through which air flows in a hollow state. Since the heat from 15 is shielded, the temperature rise of the operation unit 25 is reduced, and the operation unit 25 is not touched by placing the pan or the like on the heat insulation wall 28, so that the operation unit 25 is erroneously operated with the pan or the like. It is possible to prevent the gas stove from operating unexpectedly. In particular, since a temperature detector 33 is provided in the heat shield wall 28 to detect the temperature of the flowing air, the degree of heat influence from the flame of the burner can be detected quickly and accurately, and the temperature detector 33 Since the metal element cover 33a is directly fixed to the heat shield wall 28, the degree of heat influence from the flame of the burner 15 can be accurately detected by radiant heat and heat conduction, and accurate avoiding operation without malfunction is possible. It can be carried out.

  In addition, since the operation unit 25 is configured by a soft touch method such as a tact switch, a capacitance switch, and the like that operates by being touched lightly, the operation unit 25 can be configured with a thickness similar to that of the top board 13, which is advantageous in terms of design. Of course, the top plate can be easily cleaned. When the top plate 13 is made of heat-resistant tempered glass, the operation unit 25 can be configured as a capacitance type switch, and the user faces the operation unit that is a capacitance type switch. It is only necessary to touch the upper surface of the heat-resistant tempered glass with a finger. In the above-described embodiment, the operation unit installation unit 26 is slightly raised from the top surface of the top plate 13, but may be slightly lowered from the top surface of the top plate 13. Alternatively, it may be flush with the top surface of the top plate 13.

  Further, since the signal transmission between the control means 23 and the operation unit 25 of the gas flow rate control device 16 is performed by a wired cable of the flat cable 24, the entire operation unit installation unit 26 provided with the display unit 27 and the operation unit 25 is provided. Can be detachably attached to the top plate 13 to provide a remote operation method that is a remote control, which can be used more conveniently.

  In the above-described embodiment, the gas stove operating portion 25 is disposed laterally on the front peripheral portion 13a that is the front peripheral portion on the top surface of the top plate 13, but the left peripheral portion or the right peripheral portion of the top plate 13 is used. In addition, it is possible to provide an operation portion separately for each of the front side peripheral portion, the left side peripheral portion, and the right side peripheral portion on the top surface of the top plate 13, and the same effect as the present invention can be expected.

  Moreover, in the said embodiment, although the signal transmission between the control means 23 of the gas flow control apparatus 16 and the operation part 25 is performed by the wire using the flat cable 24, you may perform by radio | wireless. In this case, it is necessary to add a transmission unit and a reception unit to the control means 23 and the operation unit 25. In the case of a wireless system, the operation unit 25 is detachably installed on the top surface of the top plate 13 as a remote operation unit. A configuration using a remote control method is also possible.

  In the above embodiment, the present invention is applied to the built-in gas stove. However, the same configuration can be applied to the operation unit of the stationary gas table, and the same effect as the present invention can be expected.

  In the above embodiment, the gas flow control device 16 is operated by a motor to supply and shut off the gas and adjust the gas flow rate. However, the present invention is not limited to this, and the object can be achieved. Various changes can be made within the range.

  Further, the above embodiment may be a notification unit instead of the display unit 27, and can be variously modified within the scope of the object of the present invention.
