Description

  The present invention relates to a gas stove device including a plurality of gas burners.

  In this type of gas stove apparatus, a plurality of gas burners are provided on the top plate arranged on the upper surface, and the gas burners are often arranged in a creel chamber opened on the front surface. Since the plurality of gas burners are individually extinguished, a thermal power adjusting device for adjusting the flow rate of each gas is attached to a gas supply pipe that branches the gas introduced from an external gas stopper to each gas burner.

  Such a gas stove device is known in which a thermal power adjustment amount performed by a user is detected by a sensor, and a gas flow rate is adjusted by a motor in accordance with the thermal power adjustment amount (see, for example, Patent Document 1). . This gas stove device is provided with an electromagnetic safety valve that opens and closes a gas passage in addition to a heating power adjustment mechanism that adjusts the flow rate of gas. This electromagnetic safety valve is normally closed, but if the valve body is forced to open by pushing it from the outside with a rod or the like, the valve body is attracted and held by the built-in electromagnet. is there. This electromagnetic safety valve reliably prevents the raw gas from leaking out of the gas burner when the gas burner is extinguished, and releases the adsorption of the valve element by the electromagnet during the fire extinguishing operation or when the gas burner goes off, and the gas Used to block flow.

  In a conventional gas stove device, as the above-mentioned thermal power control device, an electromagnetic safety valve and a thermal power control mechanism are integrally configured and a single motor is attached, and each gas burner is forced to open the electromagnetic safety valve at the time of ignition and thermal power by the thermal power control mechanism Adjustment is performed by the single motor.

Japanese Patent Laying-Open No. 2006-189231 (FIGS. 3 and 4)

  In the above conventional gas stove device, in order to open the electromagnetic safety valve, the valve body must be opened against the urging force that urges the valve body in the valve closing direction. Is required. On the other hand, a relatively small torque may be used to adjust the thermal power. However, since a single motor is used to open the electromagnetic safety valve and adjust the thermal power for each gas burner, sufficient thermal power can be adjusted with a motor with low power consumption. This is done with a large motor with large power consumption.

  Although the operating time of the motor for opening the electromagnetic safety valve is relatively short, the thermal power adjustment must continue to operate the motor for a longer time, so when using a dry cell as a power source for driving the motor, the dry cell There is also a problem that the consumption of power increases.

  Then, this invention makes it a subject to provide the gas stove apparatus which does not produce said malfunction, when controlling supply of the gas to a gas burner in view of said problem.

In order to solve the above problems, a gas stove device according to the present invention includes a plurality of gas burners, and is provided with a gas supply pipe that individually supplies gas to each of the plurality of gas burners. Two gas supply pipes are each provided with an electromagnetic safety valve that moves the rod by a motor and presses the valve body to open the valve, and a thermal power adjusting means that adjusts the thermal power of the gas burner by increasing and decreasing the gas flow rate by an electric actuator. In the gas stove device provided, an electromagnetic safety valve provided in each of the two gas supply pipes of the gas supply pipes is connected to the positive direction of one motor different from the electric actuator that drives the heating power adjusting means. the rotation is brought into contact with the rod to the valve body of the solenoid-safety valve to select only one of the electromagnetic safety valve, and is pressed by the valve opening, the reverse direction of the motor Of retracting the rod from the valve body of the one electromagnetic safety valve above the rotation, as well as releasing the pressure for the valve body, and selects the other of the electromagnetic safety valve and open it presses the valve body of the other of the electromagnetic safety valve It is characterized by being made to valve.

In the past, each gas burner was used to open the electromagnetic safety valve and adjust the thermal power with a single large motor. However, the solenoid valve was opened with a large motor separate from the low-power electric actuator that adjusts the thermal power. In addition, by configuring the two electromagnetic safety valves, which are respectively arranged in the two gas supply paths to the two gas burners, to be opened by one large motor, the large motor to be used The number of the gas burners is shared by two gas burners, and is halved with respect to the configuration provided individually. Specifically, one of the two electromagnetic safety valves is selected by rotating the motor in the forward direction , and the valve body of the selected electromagnetic safety valve is pressed to open, and the motor is moved in the reverse direction. The other electromagnetic safety valve is selected by rotation , and the valve body of the other electromagnetic safety valve is pressed to open. In addition, since the thermal power adjustment can be performed with a small electric actuator with low power consumption, the power consumption is particularly small even when a dry battery is used as a power source for driving.

For example, the two electromagnetic safety valves that are alternately selected by one motor and that are opened when the valve body is pressed are provided in parallel so that the opening and closing valve directions are the same direction. It is conceivable to provide a rod with respect to each other and to connect both rods with a connecting mechanism that alternately advances and retracts.

Alternatively, one rod that is advanced and retracted by the one motor is provided, the one electromagnetic safety valve is selected at one end surface of the rod , and the valve body is pressed to open the valve, and the other end surface is opened. The other electromagnetic safety valve may be selected and the valve body may be pressed to open.

  As is clear from the above description, the present invention employs a configuration in which the opening of the electromagnetic safety valve and the heating power adjusting means are separated and operated independently, so that the required minimum output can be achieved. By adjusting the thermal power with a small number of small electric actuators, the overall power consumption can be reduced. In addition, since the two systems of electromagnetic safety valves can be opened by a single motor, the number of large motors that generate torque necessary for opening the electromagnetic safety valves can be reduced.

  Referring to FIG. 1, reference numeral 1 denotes a gas stove device (hereinafter simply referred to as a gas stove) in which an on-off valve portion including an electromagnetic safety valve and a thermal power adjustment unit (thermal power adjustment means) are incorporated. The gas stove 1 is provided with two gas burners 11 and 12 on the upper surface, and a grill burner 13 in a grill box opened on the front surface. And the fire extinguishing button 11a, 12a, 13a is provided for every burner. For example, when the gas burner 11 is ignited, if the point extinguishing button 11 a is pushed, the point extinguishing button 11 a that is flush with the front panel protrudes toward the front side, and gas is supplied to the gas burner 11 in the gas stove 1. The electromagnetic safety valve disposed in the gas supply pipe is opened, and the heating power is adjusted so that the heating power is optimal for the ignition of the gas burner 11.

  Referring to FIG. 2, a gas supply pipe is branched from main valve 14 to each burner 11, 12, 13. The gas burner 11 and the gas burner 12 have the same configuration, and the thermal power control unit 2 is disposed in the gas supply pipe. The heating power adjusting unit 2 drives the needle valve 22 with, for example, a motor 21 which is an example of a small electric actuator, and the amount of gas supplied to the gas burners 11 and 12 by operating the motor 21 corresponds to low heat. It can be adjusted from the flow rate to the flow rate corresponding to a strong fire.

  An on-off valve portion 3 is disposed on the upstream side of the both heating power adjusting portions 2. The on-off valve portion 3 incorporates an electromagnetic safety valve 41 that shuts off the gas supply to the gas burner 11 and an electromagnetic safety valve 42 that shuts off the gas supply to the gas burner 12. The electromagnetic safety valves 41 and 42 are configured to be opened alternatively.

  A first embodiment of a specific configuration of the on-off valve section 3 is shown in FIGS. The two electromagnetic safety valves 41 and 42 are arranged close to each other in parallel. Then, rods 32 and 33 for pushing the valve bodies of both electromagnetic safety valves 41 and 42 to forcibly open them are arranged to face the valve bodies of the electromagnetic safety valves 41 and 42, respectively.

  Both rods 32 and 33 are connected to sliders 35 and 36, respectively. Therefore, for example, when the slider 35 slides toward the electromagnetic safety valve 41, the rod 32 approaches the valve body, and further presses the valve body to forcibly open the electromagnetic safety valve 41. Similarly, when the slider 36 slides toward the electromagnetic safety valve 42 with respect to the electromagnetic safety valve 42, the rod 33 forcibly opens the electromagnetic safety valve 42.

  Both sliders 35, 36 are engaged with elongated holes 34 a provided on both sides of one swing member 34. The swing member 34 is attached to the rotating shaft of the motor 31. When the motor 31 rotates forward, one of the long holes 34a approaches the electromagnetic safety valve, and the other moves away from the electromagnetic safety valve. Therefore, for example, if the slider 35 is engaged with one of the elongated holes 34a, the slider 35 approaches the electromagnetic safety valve 41 and forcibly opens the electromagnetic safety valve 41. At this time, the slider 36 on the electromagnetic safety valve 42 side slides away from the electromagnetic safety valve 42, so that the electromagnetic safety valve 42 is not forcibly opened.

  On the contrary, if the motor 31 rotates in the reverse direction, the slider 35 slides away from the electromagnetic safety valve 41 and the slider 36 slides in a direction approaching the electromagnetic safety valve 42, so that the electromagnetic safety valve 42 is forcibly opened. Become.

  Thus, by rotating the motor 31 forward and backward, either one of the two electromagnetic safety valves 41 and 42 is selectively forcedly opened. Although the swing member 34 is used in the first embodiment, the second embodiment is shown in FIGS. 5 and 6.

  In the second embodiment, the sliders 56 and 57 for opening the electromagnetic safety valve 41 and the electromagnetic safety valve 42 are engaged with the elongated hole 53 of the gear 51 and the elongated hole 54 of the gear 52, respectively. Both gears 51 and 52 mesh with each other, so that both gears 51 and 52 always rotate in opposite directions. Therefore, when the gear 51 is rotated forward by the motor 31 and the slider 56 is slid in the direction approaching the electromagnetic safety valve 41 to forcibly open the electromagnetic safety valve 41, the gear 52 is reversed and the slider 57 is moved to the electromagnetic safety valve 42. Therefore, the electromagnetic safety valve 42 is not forcibly opened.

  Conversely, when the gear 51 is reversed, the slider 56 slides away from the electromagnetic safety valve 41, but the gear 52 rotates forward, so the slider 57 is slid toward the electromagnetic safety valve 42 to force the electromagnetic safety valve 42. Open the valve.

  In the first and second embodiments, two sliders are used, but a configuration using one slider can be adopted as in the third embodiment shown in FIG. .

  As shown in FIG. 7, two electromagnetic safety valves 41 are provided opposite to each other on the same axis, and one rod 6 that functions as a slider is disposed between both electromagnetic safety valves 41 and 42. A rack 62 was provided on the rod 6, and a pinion gear 61 was engaged with the rack 62. Therefore, when the pinion gear 61 is rotated forward and backward, the rod 6 reciprocates. For example, when the pinion gear 61 is rotated forward and the one end 63 of the rod 6 is moved toward the electromagnetic safety valve 41, the electromagnetic safety valve 41 is opened. At this time, the other end 64 of the rod 6 is moved away from the electromagnetic safety valve 42. 42 is not opened. Conversely, when the pinion gear 61 is reversed and the rod 6 is slid in the direction approaching the electromagnetic safety valve 42, the other end 64 opens the electromagnetic safety valve 42, but the one end 63 moves in a direction away from the electromagnetic safety valve 41. The electromagnetic safety valve 41 does not open. By the way, in said embodiment, although demonstrated with the motor as an electric actuator which drives a thermal-power control part, you may use a solenoid as things other than a motor, for example.

  In addition, this invention is not limited to an above-described form, You may add a various change in the range which does not deviate from the summary of this invention.
