Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a timer device that electrically starts combustion after a certain period of time set by a timer as a "good morning timer."

[Conventional technology and problems]

The main conventional mechanism of this type is to attach an electromagnetic on-off valve to the fuel flow path and link the ignition operation and the opening of the valve.

The disadvantage of this mechanism is that even if the combustor is powered by electricity and can be manually ignited by a match, the electromagnetic on-off valve will remain closed during a power outage and cannot be used at all; if a power outage occurs while the combustor is in use, the Although it is definitely safe, it has the drawback that it is completely inconvenient to use, as combustion stops. For this reason, instead of the electromagnetic on-off valve, a timer was proposed that mechanically opens the fuel on-off valve and simultaneously closes the ignition electric circuit after a certain period of time has elapsed, completely solving the problems associated with using the electromagnetic on-off valve. Ta. However, the simultaneous operation of the fuel on-off valve and the timer switch, which uses the electric circuit as a positive path, requires extremely high precision due to its construction, and if the accuracy deteriorates and the timing is off, a large amount of energy will be generated before the timer switch closes. Fuel may be supplied to the combustor, and if you use an unpowered timer that uses a spring as a timer, the timer will set the timer - when the fuel is supplied after a certain period of time, it will ignite if there is a power outage. The device does not work and is extremely dangerous. [Object of the Invention] The present invention solves the above problems and provides a timer device suitable for a combustor that can burn without relying on electricity during a power outage.

Electricity is applied to the solenoid 6 via Q. This causes the electromagnetic drive body 7 to move to the suction position, which disengages from the locking part 8, and the return spring 14' causes the movable tool 4 to return to the position before manual setting. As a result, the fuel on-off valve 5 becomes a barrier.

Therefore, a combustor that can be lit by a match can be used even during a power outage.

[Explanation of action]

This invention with the above configuration sets the timer 2 and ignition time, sets the main fuel valve (not shown) as a barrier, sets the movable tool 4, opens the fuel on-off valve 5, and closes the operation switch. The combustor can be ignited after a certain period of time.

That is, when the timer switch 1 is opened after a certain period of time, the solenoid 6 is energized, and the fuel on-off valve 5 is opened, allowing fuel to be sent to a burner (not shown). Further, when the timer switch 1 is closed, the ignition heater 16 and the combustion fan motor 17 are energized, so that the fuel sent to the burner can ignite and start combustion. In the embodiment, the solenoid 6 that makes the movable tool 4 return to its original position is not dedicated, but also serves as the solenoid 6 that operates the fuel flow control valve 11 in combination with the switch 10, and immediately after ignition, the solenoid 6 is de-energized. The electromagnetic driver 7 presses the fuel flow control valve 11 to allow a small amount of fuel to flow. When the burner combustion stabilizes, the thermostat 18 switches, energizes relay A, and contacts a-1 and a-
2 is successful, the ignition heater 16 is de-energized, the solenoid 6 is energized, and the electromagnetic driver 7 releases the fuel flow rate switching valve 11 to allow a large amount of fuel to flow.

Therefore, if a room thermostat or the like is attached to the circuit of the solenoid 6, the combustion amount of the burner can be controlled depending on the room temperature. To stop combustion in the burner, open the main fuel valve (not shown) and open the operation switch. After the burner burns the remaining fuel, when the thermostat 18 cools down and returns to its normal state, relay A becomes de-energized and the contact When a-1 and a-2 are switched, the combustion fan motor 17 also stops rotating, and combustion is completely stopped. By the way, in this invention, the fuel on-off valve 5 is not directly opened and closed by the solenoid 6, nor is it directly opened and closed in conjunction with the setting of the timer 2.
A movable tool 4 that is manually set is interposed between the solenoid 6 and the fuel on-off valve 5, and the movable tool 4 opens the fuel on-off valve 5.
is closed, and the electromagnetic driver 7 of the solenoid 6 keeps the fuel on-off valve 5 closed.Since the solenoid 6 is used to make the movable member 4 return repeatedly, the barrier of the fuel on-off valve 5 is the timer. This can now be done at the same time as switch 1 is closed.

Furthermore, even if the setting of the timer 2 and the setting of the movable fixture 7 are linked, the movement is only the opening operation of the fuel on-off valve 5, and the opening operation is dependent on the timer switch 11, so the timer 2 and the movable fixture 4 to improve operability, the fuel on-off valve 5 is opened only by the timer switch 1.
It is now possible to do this at the same time as the Sekiro. Furthermore, if the electromagnetic actuator 6 can be operated manually using the manual operation knob 9, the movable member 4 in the moving position can be moved back and forth, and the fuel on-off valve 5 becomes a barrier, so that combustion can be maintained even during a power outage. The equipment is now ready for use.

In addition, the electromagnetic drive body 7 that releases the lock of the movable shell 4 is a solenoid 6.
Since the solenoid 6 is required only when the movable tool 4 is in the moving position, the movable tool 4 is driven by After the double return, the switch 10' allows the circuit of the solenoid 6 to be used for other purposes to open the fuel on-off valve 5.

〔Effect of the invention〕

As described above, in this invention, the timer switch 1, which is a timer contact, serves as the fuel on-off valve 5, which allows fuel to flow to the burner and energizes the ignition heater as well as when using a solenoid valve. This prevented problems such as failure to ignite and abnormal combustion.

Furthermore, in order to improve operability, when the movable tool 4 and the timer 2 are moved, the timer switch 1 and the fuel on-off valve 5 operate simultaneously, making it possible to prevent ignition failure and abnormal combustion that are common in the past. .

- Furthermore, according to the configuration of the present invention, it is possible to use the combustor when the solenoid valve is used by attaching the manual operation knob 9, which improves the use of the combustor.

In addition, the fuel on-off valve 5 and the fuel flow rate switching valve 11 that are attached to the oil amount regulator 12 can be used as they are, and the solenoid 6 for changing the fuel flow rate can also be used for the maid of the movable tool 4. This is an excellent invention with a wide range of applications, as the entire control device can be provided at low cost.
