Description

  The present invention relates to an oven apparatus including a built-in oven incorporated in a system kitchen.

  Mobile gas equipment such as gas stoves and gas fan heaters are equipped with safety devices that can detect vibrations and stop operation when an earthquake occurs. This type of safety device is not normally provided in a built-in oven incorporated in a system kitchen as shown in Patent Document 1, for example. This is because the built-in oven is fixed to the system kitchen, so there is no risk of falling like a mobile gas device. In addition, when the built-in oven is a gas oven, the gas supplied to the entire building is This is also because the microcomputer type gas meter that has been put into practical use in recent years is designed to be shut off when an earthquake occurs.

  However, even though there is no fear of falling, it is a safety problem that the built-in oven that performs cooking after an earthquake occurs is a safety issue, and even if the built-in oven is a gas oven, The built-in oven may burn using the residual gas in the gas pipe.

  In recent years, some built-in ovens are provided with a vibration sensing device for detecting vibration as a safety device and a control device for stopping the operation of the built-in oven when vibration is detected by the vibration sensing device.

However, when the built-in oven is provided with a vibration-sensing device in this way, there is a problem that vibration is easily detected when the oven door of the built-in oven is opened and closed, and vibration caused by an earthquake cannot be detected accurately.

When the vibration is detected by the vibration sensing device 33, the control unit closes the stove electromagnetic on-off valve 30 and stops the supply of combustion gas to the built-in stove 4. With this configuration, when an earthquake occurs, the operation of the built-in oven 3 can be stopped using one vibration sensing device 33 and the supply of combustion gas to the built-in stove 4 can be stopped, thereby reducing the cost.

  A third aspect of the present invention provides the control unit according to the second aspect, wherein the control unit is provided in the built-in oven 3, and the control unit detects vibration by the vibration sensing device 33 when the built-in oven 3 is operated and stopped. In this case, the stove electromagnetic on-off valve 30 is closed. With this configuration, the supply of the combustion gas to the built-in stove 4 can be stopped regardless of the operation state of the built-in oven 3, and the safety is further enhanced.

  In the present invention, when the oven door of the built-in oven is opened and closed, the vibration detection device can prevent the vibration from being erroneously detected and stop the built-in oven, and the vibration at the time of the earthquake can be accurately detected by the vibration detection device. Thus, the built-in oven can be shut down reliably when an earthquake occurs.

To the space 14. The front of the space 14 is closed by a retractable retractable door 37, and the indoor gas pipe 12 is introduced into the space 14 from below the floor 5 or behind the wall 15. The indoor gas pipe 12 is connected to the upstream end of the gas supply pipe 13 via a main plug 16 formed of an electromagnetic on-off valve that can be manually opened and closed in the space portion 14. The downstream side of the gas supply pipe 13 branches in the oven body 6 into two flow paths, an oven side branch pipe 13a and a stove side branch pipe 13b, and the downstream end of the oven side branch pipe 13a is connected to the oven burner 9. The stove side branch pipe 13b is pulled out from the oven body 6 and then connected to the built-in stove 4. Note that the upstream side of the indoor gas pipe 12 may be provided with a microcomputer type gas meter shown in the background art for shutting off the gas supply to the entire building when an earthquake occurs.

  The oven-side branch pipe 13 a of the gas supply pipe 13 is provided with an oven electromagnetic open / close valve 17. The oven electromagnetic open / close valve 17, the oven igniter 10, the fan 11, the temperature detection sensor, and the alarm buzzer 29 provided in the built-in oven 3 are connected to and controlled by the control device 18 built in the oven body 6. The

  An oven operation unit 19 for operating the built-in oven 3 is provided on the upper part of the front surface of the oven body 6. As shown in FIG. 4, the operation unit 19 for the oven includes an operation switch 20 that switches between “ON” and “OFF” of operation, a temperature setting switch 21 that sets the heating temperature, a time setting switch 22 that sets the heating time, and a start switch. 23, and these switches 20 to 23 are connected to the control device 18. The oven operation section 19 is provided with a display section 24 for displaying the heating temperature, heating time, etc., an operation display lamp 25 that is turned on when the built-in oven 3 is operated, and a combustion display lamp 26 that is turned on when the oven burner 9 is burned. These are also connected to the control device 18. As shown in FIG. 1, power supply to the control device 18 of the oven body 6, the oven igniter 10, the fan 11, the oven electromagnetic on-off valve 17, the notification buzzer 29, etc. 14 is connected to an external power source through an outlet 28 installed on the floor 5 constituting the lower surface of the main body 14.

  When cooking is performed in the built-in oven 3, first, the operation switch 20 is operated as shown in FIG. As a result, the control device 18 turns on the operation display lamp 25 and simultaneously accepts the operations of the temperature setting switch 21, the time setting switch 22, and the start switch 23. In this state, the heating temperature and the heating time are set by the temperature setting switch 21 and the time setting switch 22, and then the start switch 23 is operated. As a result, the control device 18 opens the main plug 16 and the electromagnetic solenoid valve 17 for the oven and injects combustion gas from the oven burner 9. At the same time, the oven burner 9 is ignited by the oven igniter 10. Start. Thereafter, when the temperature in the combustion chamber becomes higher than the set temperature by the temperature detection sensor, the control device 18 closes the oven electromagnetic on-off valve 17 to stop the combustion of the orb burner, and simultaneously turns off the combustion display lamp 26 and also burns the combustion. When the room temperature falls below the set temperature, the control for repeatedly opening the electromagnetic solenoid valve 17 for the oven and igniting the oven burner 9 with the oven igniter 10 and turning on the combustion indicator lamp 26 is repeated. Keep the temperature in the combustion chamber constant. When the set heating time has elapsed, the control device 18 stops the operation of the fan 11 and closes the oven electromagnetic on-off valve 17 to stop the combustion of the oven burner 9. At the same time, the temperature setting switch 21, time The operation of the setting switch 22 and the start switch 23 is not accepted, that is, the operation is turned off, and the operation display lamp 25 is simultaneously turned off and the operation buzzer 29 notifies the operation stop.

  Here, the start switch 23 of this example is a start / stop switch that also serves as a stop switch that stops the operation of the fan 11 and closes the electromagnetic solenoid valve 17 for the oven before the heating time elapses. Further, when the operation switch 20 is pushed in the operation “ON” state, the operation is set to the “OFF” state, that is, in this case, the operation of the fan 11 is stopped and the electromagnetic solenoid valve 17 for the oven is closed simultaneously. The temperature setting switch 21, the time setting switch 22, and the start switch 23 are not accepted. The oven body 6 is provided with an oven extinguishing safety device (not shown), and the oven extinguishing safety device always detects the presence or absence of flame when the oven electromagnetic on-off valve 17 is opened. If the flame of the oven burner 9 is extinguished while the oven electromagnetic open / close valve 17 is opened, the control device 18 automatically closes the oven electromagnetic open / close valve 17 to prevent the outflow of raw gas and simultaneously notify. A notification is given by the buzzer 29 and an error is displayed on the display unit 24.

  On the other hand, the built-in stove 4 arranged at the upper part of the system kitchen 1 includes a stove part 4a exposed on the upper surface of the system kitchen 1 and a grill part 4b arranged just above the oven body 6, as shown in FIG. The pan placed on the stove part 4a can be heated, and the fish etc. put in the grill part 4b by opening the front door can be heated. A stove burner (not shown) provided on the stove 4a and a grill burner (not shown) provided on the grill 4b communicate with the stove branch 13b of the gas supply pipe 13, respectively. Fuel gas can be supplied from 13b. Each of the stove unit 4a and the grill unit 4b has a switching valve (not shown) comprising an electromagnetic on-off valve that uses a battery with a built-in power supply in the built-in stove 4 or an on-off valve that operates mechanically in conjunction with an ignition switch 32 described later. These switching valves can switch whether or not the combustion gas is supplied from the stove side branch pipe 13b to each of the stove burner and the grill burner. A stove igniter (not shown) that uses a battery built in the built-in stove 4 as a power source is provided in each of the stove unit 4a and the grill unit 4b.

  The built-in stove 4 is provided with a stove operation unit 31 exposed at the upper front of the system kitchen 1. By pressing each ignition switch 32 of the stove operation unit 31, the changeover valve is opened and a stove burner or Combustion gas can be supplied to the grill burner and the stove burner can be ignited by the stove igniter (not shown), or the grill burner can be ignited by the grill igniter (not shown). . Further, by pressing the ignition switch 32 again to return to the initial position, the switching valve is closed to stop the supply of the combustion gas to the burner for the stove or the burner for the grill, to stop the combustion of the burner for the stove, The combustion of the grill burner can be stopped. Here, the built-in stove 4 is provided with a stove-extinguishing safety device (not shown), and the presence of flames in the stove burner or grill burner when each switching valve is opened by the stove-extinguishing safety device When the flame goes out with each switching valve opened, each switching valve is automatically closed to prevent the raw gas from flowing out.

  The oven device 2 has a vibration sensing device 33 that is separate from the built-in oven 3 and can be installed at a position different from the built-in oven 3, and when the vibration sensing device 33 detects vibration during operation of the built-in oven 3. And a control unit for stopping the operation of the built-in oven 3.

  The vibration-sensing device 33 of this example is installed on the upper surface of the floor 5 of the building where the system kitchen 1 is installed, specifically, the portion constituting the bottom surface portion of the space portion 14 of the floor 5, and the oven body 6 constituting the control unit. Is connected to the control device 18 provided via the lead wire 34. Specifically, the vibration sensing device 33 is installed on the floor surface below the oven body 6.

  Then, when the operation switch 20 is operated and the built-in oven 3 is in the operation “ON” state as shown in FIG. 6, the control device 18 receives a detection signal from the vibration sensing device 33 when an earthquake occurs. When the vibration detected by the vibration sensing device 33 is greater than a predetermined seismic intensity, the oven electromagnetic on-off valve 17 is closed and the operation of the fan 11 is stopped. At the same time, the operation switch 20 and the temperature setting switch 21 are stopped. The operation is set to “OFF” as a locked state that does not accept the operation of the switch related to the operation of the built-toy oven 3 including the time setting switch 22 and the start switch 23, and at the same time, the earthquake detection display provided in the operation unit 19 for the oven The lamp 36 is turned on and notified by the notification buzzer 29, and an error is displayed on the display unit 24 together.

  After that, when the release switch 35 provided in the oven operation unit 19 is operated, the control device 18 is in a state of accepting the operation of releasing the lock state of each of the switches 20 to 23 and simultaneously operating the oven. The earthquake detection display lamp 36 provided in the unit 19 is turned off and the notification by the notification buzzer 29 is stopped, and the error display on the display unit 24 is also turned off. Thus, the user can stop the earthquake and operate the release switch 35 after confirming that there is no abnormality such as damage to the built-in oven 3, so that the operation of the built-in oven 3 can be resumed.

  In this way, the oven device 2 is provided with a control unit (control device 18) for stopping the operation of the built-in oven 3 when vibration is detected by the vibration sensing device 33 during the operation of the built-in oven 3. Sometimes, the operation of the built-in oven 3 can be stopped. In particular, when the built-in oven 3 is a gas oven as in this example, the combustion of the oven burner 9 can be stopped when an earthquake occurs, and the indoor gas pipe 12 can be stopped after the earthquake occurs. It is possible to prevent the built-in oven 3 from burning using the remaining gas. Moreover, since the vibration sensing device 33 can be installed at a position different from the built-in oven 3 such as the floor 5 of the building, when the oven door 8 of the built-in oven 3 is opened or closed, the vibration is erroneously detected and the built-in by the control device 18 is detected. The oven 3 can be prevented from being stopped, and the vibration at the time of the earthquake can be accurately detected by the vibration sensing device 33 installed on the floor 5 or the like, and the operation of the built-in oven 3 can be surely stopped when the earthquake occurs.

  Next, another example of the oven apparatus 2 different from the above will be described. In addition, about the same structure as the said example, the same number is provided and the overlapping description is abbreviate | omitted.

  In the oven apparatus 2 of this example, as shown in FIG. 7, the stove side electromagnetic branch valve 13b is provided in the stove side branch pipe 13b of the gas supply pipe 13 separately from the above-described switching valve. As shown in FIG. 9, the electromagnetic on-off valve 30 is connected to the control device 18 via a lead wire 38, and the power source is the built-in oven 3. The control device 18 constituting the control unit is set to close the stove electromagnetic on-off valve 30 and stop the supply of the combustion gas to the built-in stove 4 when vibration is detected by the vibration sensing device 33. That is, when the operation switch 20 is operated and the built-in oven 3 is in the operation “ON” state as shown in FIG. 8, the control device 18 detects the vibration detected by the vibration sensing device 33 at a seismic intensity higher than a preset value. As in the example, the electromagnetic solenoid valve 17 for the oven is closed, the operation of the fan 11 is stopped, the operation of the built-in oven 3 is set to “OFF”, and the earthquake detection display lamp 36 is turned on. Then, the notification buzzer 29 is notified and an error is displayed on the display unit 24. At the same time, the stove electromagnetic on-off valve 30 is closed to stop the supply of the combustion gas to the built-in stove 4. As a result, when the earthquake occurs, the operation of the built-in oven 3 is stopped and at the same time, the supply of the combustion gas to the built-in stove 4 is stopped to stop the combustion of the burner for the stove part and the burner for the grill part. Thereafter, when the release switch 35 is operated, the control device 18 is in a state of accepting the operation of each switch as in the example, the earthquake detection display lamp 36 is turned off, and the notification by the notification buzzer 29 is stopped. The error display on the display unit 24 is turned off, and at the same time, the stove electromagnetic on-off valve 30 is opened. As a result, the user can stop the earthquake and operate the release switch 35 after confirming that there is no damage such as damage to the built-in oven 3 or the built-in stove 4 so that the operation of the built-in oven 3 and the built-in stove 4 can be resumed. It has become. If an earthquake occurs when the built-in stove 4 is used, the oven electromagnetic on-off valve 17 is closed in a state where the ignition switch 32 is positioned at the pushing position for opening each switching valve. Even if the release switch 35 is operated in this state to open the stove electromagnetic on-off valve 30, the stove-off safety device for the stove of the built-in oven 3 is in operation, so that each switching valve of the built-in stove 4 at this time is closed. In this case as well, no raw gas is released from the burner for the stove part or the burner for the grill part of the built-in stove 4. In other words, in this case, the built-in stove 4 can be restored to a normal state by pressing each ignition switch 32 in the push-in position once.

  As described above, in this example, as in the case of the example, when the earthquake occurs, the vibration sensing device 33 can detect the earthquake and stop the operation of the built-in oven 3. In addition, the vibration sensing device 33 is used to move to the built-in stove 4. The combustion of the stove burner and the grill burner can be stopped by stopping the supply of the combustion gas.

  Note that the control device 18 in this example is configured to open and close the stove electromagnetically even when the vibration of the built-in oven 3 is stopped (that is, when the operation is “off”), even if vibration is detected by the vibration sensing device 33 that is greater than the seismic intensity set in advance. Although the open / close state of the valve 30 may not be changed, that is, the valve 30 may be left open, the control device 18 constituting the control unit is stopped when the built-in oven 3 is stopped (ie, when the operation is turned off) as shown in FIG. It is preferable to set the stove electromagnetic on-off valve 30 to be closed when vibration is detected by the vibration sensing device 33.

  In the example shown in FIG. 10, when the built-in oven 3 is stopped, the control device 18 closes the stove electromagnetic on-off valve 30 and simultaneously detects an earthquake when the vibration sensing device 33 detects vibration exceeding the seismic intensity set in advance. The display lamp 36 is turned on, a notification is given by the notification buzzer 29, and an error is displayed on the display unit 24. As a result, even if the built-in oven 3 is stopped when an earthquake occurs, as long as power is supplied to the built-in oven 3 from the external power source, the supply of the combustion gas to the built-in stove 4 is stopped to The combustion of the burner for the section and the burner for the grill section can be stopped. After that, when the release switch 35 is operated, the control device 18 opens the stove electromagnetic on-off valve 30, simultaneously turns off the earthquake detection display lamp 36, stops the notification by the notification buzzer 29, and displays the display unit 24. Turn off the error display. Thus, the user can stop the earthquake and operate the release switch 35 after confirming that there is no abnormality such as damage to the built-in oven 3 or the built-in stove 4 so that the operation of the built-in stove 4 can be resumed. If an earthquake occurs when the built-in oven 3 is stopped and the built-in stove 4 is used, the oven electromagnetic on-off valve 17 is in a state where the ignition switch 32 is located at the push-in position for opening each switching valve. In this state, even if the release switch 35 is operated to open the stove electromagnetic on-off valve 30, the built-in oven 3 has a built-in safety device for the stove that has been turned off. Each switching valve of the stove 4 is closed, and in this case as well, raw gas is not released from the burner for the stove part or the burner for the grill part of the built-in stove 4. That is, also in this case, the built-in stove 4 can be returned to a normal state by pressing each ignition switch 32 in the push-in position once.

  In any of the above embodiments, the built-in oven 3 is a gas oven, but the built-in oven 3 may be an electric oven. Further, an electric cooking heater may be employed instead of the built-in stove 4.
