Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to an oil combustor in which the burner can be ignited after a certain time by a timer or immediately when desired.

[Conventional technology and problems]

Conventionally, when starting an oil combustor using a timer, the main method is to specify the time before you wake up so that when you wake up in the morning, the room will be heated by the oil combustor. There is a risk of falling asleep. In addition, oil burners used for boiling may be turned off even after the instruction to start combustion, and it is extremely dangerous to continue burning for a long time after ignition. For this reason, when starting operation using a timer, it is common to use a second timer that stops combustion after a certain period of time, making the burner controller complex and expensive.

[Purpose of invention]

This invention achieves the same safety performance as when a second timer is used in conjunction with the use of a single-function, inexpensive timer that closes the circuit after a certain period of time.

[Explanation of embodiments of the invention]

1 is a burner of an oil combustor, 2 is a timer ignition device that closes after a certain period of time, 3 is a direct ignition device, and the timer ignition device 2 and the direct ignition device 3 each act independently on the burner controller 8,
Start operation of burner 1. Reference numeral 4 denotes an oil tank of the oil combustor, which is composed of an oil supply section 5 connected to a cartridge auxiliary tank 9 and the like, and an oil use section 6 to which an electromagnetic pump 10 for supplying fuel to the burner 1 is attached. Reference numeral 7 denotes an on-off valve attached to the communication section 11 between the oil supply section 5 and the oil use section 6, and in the embodiment, it is constituted by a solenoid valve. In addition, the on-off valve 7 is connected to the direct ignition device 3 so that the circuit becomes open corresponding to the direct ignition device 3.
It is installed in the circuit of

[Explanation of how the idea works]

In this invention having the above structure, when the ignition device 3 is operated directly when an oil combustor is used, it acts on the burner controller 8 to start operation of the burner 1 and also opens the on-off valve 7. Therefore, oil can be sent from the oil supply section 5 to the oil use section 6 of the tank 4 via the on-off valve 7, making it possible to use the oil combustor for a long time until the direct ignition device 3 is switched. can.

On the other hand, when the timer ignition device 2 is operated and after a certain period of time the burner 1 is started by the timer ignition device 2, the on-off valve 7 remains closed and oil is sent from the oil supply section 5 to the oil use section 6. I can't. For this reason, the burner 1 automatically extinguishes the fire when the oil in the oil usage part 6 is used up, and the shape and size are designed in advance so that the burner 1 burns the amount of oil stored in the oil usage part 6 for 30 minutes or 1 hour. Once set, the second timer, which stops combustion after a certain period of time, becomes unnecessary. Even when the operation is started using the timer 2 ignition device, if the ignition device 3 is directly operated while the burner 1 is burning, the on-off valve 7 will open, and the oil will flow through the oil supply section 5.
This makes it possible to send the fuel from the fuel tank to the usage section 6, and the oil combustor does not automatically stop operating.

[Effect of idea]

As mentioned above, this invention requires a complicated and expensive control method in order to maintain safety through timer operation, but instead of using a second timer, it uses an inexpensive on-off valve and connects it directly to the ignition system. This makes it possible to obtain safety during timer operation even with an extremely simple configuration, making it an extremely practical device.

Claims (1)

[Scope of utility model registration request] It has a timer ignition device 2 that starts the operation of the burner 1 after a certain period of time, and an ignition device 3 that directly starts the operation of the burner 1 independently of the timer ignition device 2, and the oil tank 4 of the oil combustor is used to supply oil. The oil supply section 5 and the oil use section 6 communicate with each other via an on-off valve 7, and the on-off valve 7 is opened in correspondence with the ignition device 3. An oil burner featuring:
