Description

Description: TECHNICAL FIELD The present invention relates to a controller for an up-down core type petroleum combustor which uses a dry battery for ignition as a main power source.

[Prior Art] Conventional petroleum combustors that use AC power supplies have sufficient power supply capacity and high commercial value, so even if a dedicated microcomputer IC is manufactured and used, it is kept at a price range that can be purchased by the user. be able to. Further, a function of extinguishing the fire for 1 hour or 3 hours after the timer is ignited to avoid continuous use of the open type oil combustor in a closed chamber can be easily added.

However, in the case of an inexpensive oil combustor as an oil combustor, an upper and lower core type oil combustor was not provided with a function of extinguishing the fire after a fixed time due to the limitation of the power source that can be used.

[Problems to be Solved by the Invention] That is, in the case of a core upper and lower petroleum combustor, the main power source is a 3V dry battery, and the ignition device is operated by this power, and the core of the motor drive is further improved for better usability. It operates a vertical device and drives a turbofan motor to operate a suction type deodorizing device.Since they use a large current, the electric power that can be used for the control device of the oil combustor becomes very small. It is something that ends up.

Therefore, the controller is a low power consumption type CMOS type.
Although it is necessary to use ICs, CMOS dedicated microcomputer ICs are extremely expensive, and even when a long time timer is configured with logic ICs, due to the increase in power consumption and the complexity of the circuit configuration, it is eventually commercialized. However, the selling price became too high, and it was not possible to implement a safety device using a long timer on an inexpensive oil burning combustor.

[Means for Solving the Problems] The present invention focuses on a general-purpose time display timer module that uses a small battery for exclusive use as a power source, as a timer for an up-down core type oil combustor. There are some that can output an output signal, and there is also one that outputs an output signal that sounds an hourly alarm at a fixed time and an output signal that normally sounds an alarm for 1 hour from the time set by the alarm function, By inputting these output signals to the control device, the structure of the control device of the oil wick upper and lower type oil combustor is simplified.

That is, in an oil combustor having an oil tank 1, a wick 2, a wick up-and-down mechanism 3, and a combustion tube 4, which moves up and down the wick 2 manually or mechanically, the combustion tube 4 is used. Combustion detector 5 having a function of monitoring the combustion state, and combustion detector 5
Fire extinguishing mechanism 7 that drives the core lifting mechanism 3 according to the output signal of
And a timer module 6 for displaying the time, the output signal of the timer module 6 is connected to the combustion detector 5, and the output signal of the timer module 6 causes the core to pass through the fire extinguishing mechanism 7 after a certain period of ignition. The vertical mechanism 3 is operated to automatically extinguish a fire.

When the time display portion of the timer module 6 is not exposed on the surface of the frame of the oil combustor and the time display function is not used, the time timing output of the timer module 6 is connected to the combustion detector 5 to The fixed time output is connected to the fire extinguishing mechanism 7, and the ignition operation contact 8 and the reset contact 9 of the timer module 6 are interlocked with each other, and the time data of the timer module 6 is cleared for each ignition operation to ensure the time at the time of ignition. By starting from 00:00, the configuration of the control device is further simplified.

[Operation] According to the present invention having the above-described configuration, the timer module 6 for a general-purpose watch, which is manufactured in large quantities and is very inexpensive, is used as a timer element, and the output signal of the timer module 6 is controlled by the control device. The signal is used as a signal, and the timer module 6 keeps running for several years by a dedicated small battery, and there is almost no load on the dry battery used in the core up-down oil combustor.

In addition, the timer module 6 can output a signal that changes the display at regular intervals, a time signal every 30 minutes or 1 hour, and an alarm signal that operates as an alarm function, and drives the fire extinguishing mechanism 7 of the combustion detector 5. By sending the output signal of the timer module 6 to the input section, the timer module 6 functions as a long-time timer of the control device.

For this reason, a long safety timing time necessary for detecting misfire of the core lifting device and one hour after the timer ignition,
The elapsed time when continuous combustion was performed for 3 hours after manual ignition was
It can be easily known from the output signal of the timer module 6, and after the oil combustor has burned for a predetermined time, the fire extinguishing mechanism 7 operates without fail and the core lowering and extinguishing mechanism 3 enables the core down fire.

In addition, the signal from another safety device can be used to automatically knock down the seismic weight 18
Emergency fire extinguishing is also done by directly pushing down.

Reference numeral 5 is a combustion detector having a photodetector element such as a phototransistor or a photodiode in its input portion. The photodetector element 5 is attached to the upper part of the combustion cylinder 4 so as to prevent the red heat condition of the upper part of the combustion cylinder 4. The combustion state is monitored from the size of the combustion flame. Combustion is not stable in the core up-down type oil combustor until a considerable time has elapsed from the ignition operation, and it takes a long time for the red heat condition and the combustion flame condition on the upper part of the combustion cylinder 4 to become normal, and the combustion detector 5 ignites. By operating after a certain time has passed after the operation, it is possible to detect an ignition error or a defective combustion state.

Reference numeral 7 denotes a fire extinguishing mechanism that is driven by the output signal of the combustion detector 5. In the oil combustor of the embodiment, the fire extinguishing mechanism 5 operates the drive motor 11 to move the lead 2 up and down by the lead up / down mechanism 3.

Is supplied with power from the dedicated small battery 16, and the supplied LC
It can be used alone as a clock that displays the time using the D display 15. As a general usage of the timer module 6, the LCD display 15 is exposed on the front panel of an oil combustor to display the time.

The timer module 6 has terminals having various functions exposed due to the module configuration, and is assembled into a small frame body containing an alarm, for example, to complete an alarm clock. Therefore, by connecting the signal line of the timer module 6 to the control device of the core up-down type oil combustor, the control device does not need to incorporate a timer for a long time, and the combustion detector 5 for operating the fire extinguishing mechanism 7 is connected to the timer module. By sending the signal No. 6, the oil combustor is extinguished according to the output status of the signal line.

That is, the timing signal output from the timer module 6 such as a time display can be counted, and the combustion detector 5 can be operated after the combustion in the combustion cylinder 4 is stabilized. When the subsequent output signal is output as a timing signal such as a time signal and a combined signal, the extinguishing signal after a predetermined time has passed is sent to the extinguishing mechanism 7 via the combustion detector 5.

On the other hand, when the time display is not necessary, the LCD display 15 can be omitted and a signal can be taken out using the connection terminal for the display, and a time timing signal (for example, a time signal) and an output signal after a certain time has passed ( For example, when the timer module 6 outputs a wake-up signal) in a separate system and the ignition operation contact 8 and the time reset contact 9 of the timer module 6 are connected when the time display is not performed, the timer module 6 operates Each time the contact 8 is pressed, the time display is 00: 0
The combustion detector 5 and the fire extinguishing mechanism 7 which start at 0 and which receive the output signal of the timer module 6 as input can be easily configured.

[Effects of the Invention] As described above, in a core-up and down type oil combustor using a dry battery as a power source, when a price is set in a price range in which the oil combustor is sold, a mechanism for automatically extinguishing a fire after a certain period of ignition is mounted. It was considered impossible to put into practical use a product that can be continuously used for one year or more without replacing the battery. However, as in the configuration of the present invention, the high-performance timer module 6 that can be used as a timepiece is By using it as a timer element of a control device, the upper and lower wick type petroleum combustor is extinguished after a certain time of ignition.

Therefore, the safety of the core upper and lower petroleum combustors becomes as excellent as that of the fan heater using the AC power source, and it becomes impossible to carry out unsafe operation of continuing combustion for a long time in an unmanned state.

Further, the timer element incorporated in the combustion detector 5 which constitutes the main control device of the oil combustor can be omitted by using the signal of the timer module 6, the area of the control board can be reduced, and the small upper and lower core type oil can be used. It is a practical invention that can be installed in a combustor.

Further, when the clock display of the timer module 6 is stopped, the ignition operation contact 8 and the reset terminal 9 of the timer module 6 are
With the configuration in which the time display is cleared each time the ignition operation is performed by connecting with, the count of the timer module 6 always starts from zero, and despite the simple configuration, the core up-down oil combustor is always operated at an accurate time. It has become possible to control.
