Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a burner control device for a heater having a plurality of burners.

(Prior Art) Conventionally, a heater having a plurality of burners is known as a heater such as an oil stove having a relatively large scale. In addition, each burner is provided with an electric heater for ignition that vaporizes and ignites the liquid fuel.

(Problems to be solved by the invention) However, conventionally, when a plurality of burners are ignited at the same time when the heater is started, inrush currents of the heaters of the respective burners are generated at the same time, and the breaker of the power supply may drop due to an excessive current There was a problem that it had an adverse electrical effect on other devices in operation.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a burner control device for a heating machine that does not generate an excessive current even when a plurality of burners are simultaneously ignited. It is in.

(Means for Solving the Problems) In order to achieve the above-mentioned object, the present invention provides a burner controller for a heater, which controls ignition of a plurality of burners each equipped with an electric heater for ignition. The heater is provided with a delay drive means for driving each heater with a predetermined time difference when receiving an ignition command.

(Operation) According to the burner control device of the heater of the present invention, the heaters of at least two burners that receive the ignition command at the same time are driven by the heater delay drive means with a predetermined time difference.

(Embodiment) FIGS. 1 and 2 show an embodiment of the present invention.

In FIG. 1, reference numerals 1, 2, and 3 are first to third pot-type burners arranged in parallel with each other, and pots 4,5, 6 having upper ends opened.
And combustion rings 7,8,9 arranged in the pots 4,5,6, and first to third electric heaters 10,11 for ignition attached to the bottoms of the pots 4,5,6. It consists of 12 and. Also, each pot 4,
Reference numerals 5 and 6 open at the central portion of the bottom surface, and the openings are respectively communicated with the inside of the air passage 14 having a blower 13 for supplying combustion air at its one end. The blower 13 is configured so that the air volume can be switched among three levels.

15, 16 and 17 are constant oil levelers for supplying body fuel to the burners 1, 2 and 3, respectively, and through the first to third electromagnetic pumps 18, 19, 20 and oil feeding pipes 21, 22, 23. The pots 4, 5 and 6 communicate with each other. Each of the oil levelers 15, 16 and 17 is connected to a fuel tank (not shown) and always stores a predetermined amount of fuel.

Reference numeral 24 is a burner control device having a microphone computer configuration, which includes the first to third heaters 10, 11, 12 and the first to third pumps 1.
The burners 1, 2 and 3 are respectively connected to 8, 19 and 20 and the blower 13 to control the operation of the burners 1, 2 and 3 according to a program described later.

Reference numeral 25 is a timer as a heater delay driving means, which is connected to the burner control device 24.

Reference numeral 26 is an operation unit provided with a main switch, a combustion capacity changeover switch (both not shown), etc., and the combustion capacity volume V can be set in three stages of 1 to 3, and the burner control unit is provided. Connected to 24.

Now, the operation of the burner control device 24 will be described with reference to the flowchart shown in FIG.

First, when it is determined that the main switch is turned on (S1), the first heater 10 is driven (S2). Next, if the volume V of the combustion capacity set by the operation unit 26 is 1 or less, the program ends (S3). Also, the step S3
If V is greater than 1 at, the timer 25 is set to 5 seconds, for example (S4). Then, when the waiting time elapses (S
5), drive the second heater 11 (S6). Next, if V is 2 or less, the program is terminated (S7), and if V is larger than 2, the timer 25 is set again (S8). When the waiting time has elapsed (S9), the third heater 12 is driven (S1
0). Thereafter, the volume V of the combustion capacity set above is substituted for the air volume level R of the blower 13 (S11), and the blower 13 is driven at this air volume level R (S12). As a result, fresh air corresponding to the number of burner ignitions is supplied.
Subsequently, the first pump 18 is driven (S13), and if V is 1 or less, the program ends (S14). If V is greater than 1 in step S13, the second pump 19 is driven (S15). If V is 2 or less, the program ends (S16), and if V is greater than 2, the third pump 20 is driven and the program ends (S17).

As described above, the fuel supplied into the pot 4 of the burner (for example, the first burner 1) is ignited through the preheating process by the first heater 10 to obtain fresh air (solid arrow in the figure) from the blower 13. Ignite. Then, when the temperature in the pot 4 rises, the fuel is sequentially vaporized in the pot 4 and the combustion is continued without being heated by the first heater 10. Of course, the second and third
The same applies to the operation of the burners 2 and 3.

As described above, the burner control device for the heating machine according to the present embodiment is
Even if the volume V of the combustion capacity is 2 or more at the time of starting the heater, that is, the two or three burners are set to be ignited at the same time, the heater of each burner is driven by the timer 25 with a time lag. Since it is programmed, inrush current of each heater does not occur at the same time,
It is possible to reliably prevent the breaker of the power supply from dropping due to an excessive current.

In the above embodiment, the heater provided with the three burners 1, 2 and 3 is shown, but it goes without saying that a heater other than the above may be provided, and the starter as described above may be used. It is even more effective to program not only the time but also the heater to be driven with a time difference even if the number of burner ignitions is reset so as to increase by two or more during continuous operation.

(Effects of the Invention) As described above, according to the burner control device of the heater of the present invention, even when at least two of the plurality of burners are simultaneously ignited, the inrush currents of the heaters of the respective burners are the same. It does not occur, and it is possible to reliably prevent the breaker of the power supply from dropping due to an excessive current.
