Abstract

PURPOSE:To obtain an oil burner capable of saving energy and providing high advantage by detecting the usage and non usage of equipment, measuring its continuation time, comparing said time with service judgment reference duration, increasing and decreasing a setting temperature for a heater which is a vaporization means, responding with the detected values, and controlling the combustion of a burner. CONSTITUTION:A flowing water sensor 7 transmits the shutdown of equipment as a non service log criterion signal to a timer means 13 and a combustion control means 15. The combustion control means 15 outputs a timer measurement signal to the timer means 13 if the non service log criterion signal is not output yet, and the no service log criterion signal to a comparison decision means 14 respectively. When a comparison decision signal exceeds a non service log criterion time, the combustion control means 15 lowers a setting temperature for a heater 4 of a vaporization means 3 by a specified temperature if the setting temperature for the heater of the vaporization means 3 is lower than the setting temperature of the heater, and then resets the output of the non service criterion signal. When the flowing water sensor 7 detects a service state of equipment, the combustion control means 15 outputs a heater power supply control signal so that the detected temperature may become identical to the setting temperature. If the service frequency is reduced, the power supply quantity for the vaporization heater may be lowered in automatic mode so that a burner may be operated in low power consumption mode.

Description of the Related Art Conventionally, this type of control device has a heat exchanger 1, a burner 2 that heats the heat exchanger 1, and a vaporizer that sends vaporized oil to the burner 2, as shown in FIG. 3 using an oil water heater as an example. 3, a heater 4 that is built in the vaporizer 3 and vaporizes the oil, and a combustion amount adjusting means (for example,
(electromagnetic pump, etc.) 5, a running water sensor 7 as a usage state detection means for detecting running water due to the opening and closing of the collar 6, a hot water temperature setting means 8 for setting the hot water temperature, and a hot water temperature detecting means for detecting the hot water temperature. a thermistor 9, a combustion amount control means IO that outputs a combustion amount adjustment signal to the combustion amount adjustment means 5 according to the deviation between the set temperature and the hot water temperature, and a pump that pumps oil from an external tank 12 to an oil tank 11 inside the device. It was composed of 13.

Therefore, in a state where the heater is raised to a predetermined set temperature by an operation switch (not shown) or the like, the operating state detection means 7 detects the opening of the ignition valve 6, and the combustion amount adjustment means 5 controls the vaporizing section 3. The combustion supply to the boiler was adjusted according to the deviation between the set temperature and the outlet temperature.

Problems to be Solved by the Invention However, in the above configuration, in order to supply hot water at the desired set temperature in a short time after the tap is opened, that is, after the start of hot water supply, the heater of the vaporizing section must be constantly set to the predetermined vaporizing temperature. need to be kept. Therefore, since the heater of the vaporizing section is normally turned on throughout the day after it is used in the morning, the power consumption becomes extremely high, which is uneconomical.

The present invention solves this conventional problem by constantly monitoring the usage frequency of the oil combustor and increasing or decreasing the set temperature of the heater in the vaporizing section depending on the usage/non-use duration. The purpose of this invention is to provide an energy-saving and highly convenient oil combustor by automatically performing heater energization control that matches the actual situation.

Means for Solving the Problems In order to solve the above problems, the oil combustor control device of the present invention includes a usage state detection means for detecting use or non-use of the equipment, and a usage judgment from the usage state detection means. input the signal,
a timer means for measuring the usage determination signal duration; a comparison determination means for comparing the usage determination signal duration from the timer means with a predetermined usage determination continuation reference time and outputting a comparison determination signal; Depending on the comparison judgment signal,
The combustion control means increases or decreases the set temperature of the heater of the vaporizer that vaporizes the oil, and controls the combustion of the burner that burns the vaporizer.

Effect of the present invention With the above-described configuration, the usage status of the oil combustor can be constantly detected by the usage status detection means, and the usage frequency, operation and non-operation duration of the oil combustor can be constantly monitored by the timer unit and the comparison determination means. It is now possible to lower the set temperature of the vaporizer heater as time passes when it is not in use, or change the set temperature of the vaporizer heater depending on the frequency of use, reducing heater power consumption and increasing the efficiency of the oil combustor. By controlling the temperature of the vaporizing means in accordance with the actual conditions of use, it is possible to improve the durability and extend the life of the vaporizing means. Note that the same members as in the conventional example shown in FIG. 3 are given the same numbers.

Embodiments Hereinafter, embodiments of the present invention will be described based on the accompanying drawings.

FIG. 1 is a control block diagram of a control device of the present invention.

13 is a timer means for inputting the use judgment signal (such as a pulse signal according to the flow rate) sent from the use state detection means (<m water sensor) 7 and measuring the duration of time when it is in use and when it is not in use; , the usage determination signal continuation time (for example, non-use elapsed time, hereinafter referred to as non-use elapsed time) from the timer means 13 is set to a predetermined usage determination continuation reference time (non-use elapsed determination reference time, hereinafter referred to as non-use elapsed time). The comparison determination means 15 outputs a comparative determination signal indicating that the non-use elapsed determination reference time has been exceeded (determined as the determination reference time); A control signal corresponding to the non-use elapsed judgment reference time is output to the comparison judgment means 14, a comparison judgment signal which is the comparison judgment result is inputted, and the set temperature of the heater 4 of the vaporization means 3 is increased/decreased and the combustion of the burner 2 is controlled. This is a combustion control means for controlling combustion.

In the above configuration, the operation of the oil combustor control device will be explained based on the flowchart in Fig. 2.■ Flowing water sensor 7
As a result, the stoppage of use of the equipment is sent to the timer means 13 and the combustion control means 15 as a non-use determination signal.

(2) The combustion control means 15 determines whether the non-use progress determination reference signal is in the output method or not, and if it is not output, the process shifts to (2), and if it is the output method, the process shifts to (2).

(2) The combustion control means 15 outputs a timer measurement start signal to the timer means 13 and a reference signal to the comparison and determination means 14 in response to the progress of non-use.

(2) The combustion control means 15 determines the presence or absence of a comparison determination signal from the comparison determination means. That is, it is determined whether the non-use elapsed determination reference time has been exceeded.

(2) If the non-use elapsed determination reference time is exceeded in (2), it is determined whether the set temperature of the heater 4 of the vaporizing means 3 is the lower limit value (ambient temperature, that is, the heater may be turned off).

(2) If the heater set temperature is >lower limit in (2), the set temperature of the heater 3 is lowered by a predetermined temperature. moreover,
The output of the non-use determination reference signal to the comparison determination means 14 is reset.

(2) When the running water sensor 7 detects the usage state of the device, the combustion control means 15 outputs a heater energization control signal so that the heater 3 reaches the set temperature at the time of use.

Therefore, the set temperature of the heater 3 decreases without any special operation every predetermined elapsed time after the heater 3 stops being used. That is, during periods of high use, the vaporization stability maintenance temperature is always maintained, and when use is low, the amount of electricity supplied to the vaporization heater is automatically reduced, resulting in low power consumption operation.

Furthermore, the change in the set temperature of the heater 3 is not limited to the above embodiment, and for example, by rapidly increasing the heater set temperature immediately after starting and stopping use, the tar durability of the vaporizing means can be improved. Possible applications include:

Effects of the Invention As described above, according to the oil combustor control device of the present invention, the following effects can be obtained.

(1) It becomes possible to control the temperature of the heater of the vaporizing means according to the frequency of use of the oil combustor, and it is possible to automatically reduce the amount of energized power in stages from the time of stoppage of use.

(2) By controlling the temperature rise of the heater of the vaporizing means at the time of starting and stopping the use of the oil combustor, it is possible to improve the durability and extend the life of the oil combustor.
