DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a combustion control device used for a hot oil heater or the like.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 7, reference numeral 1 denotes a main body case of a petroleum hot air heater of this kind, and a tank 2 holding liquid fuel at a lower side thereof and a detachable upper part of the tank 2. A cartridge tank 3 is provided. The tank 2 has an oil level detecting means 4 such as a float type for detecting the oil level of the fuel in the tank. Refueling detecting means 4A for detecting the sky of the vehicle is provided.

[0005] Reference numeral 5 denotes a pump mounted on the upper surface of the tank 2. The pump 5 supplies the fuel from the upper end to a vaporizing section 7 kept at a predetermined temperature or higher by a heater 8 and a temperature detecting means 9 via an oil feed pipe 6. It has become.

Numeral 10 is a nozzle disposed at the tip of the vaporizing section 7, which converts the fuel gas vaporized by the vaporizing section 7 to primary air by an ejector effect which is provided in a horizontal direction at a downstream side of the vaporizing section 7. It is jetted into the mixing tube 11 to be sucked.

Reference numeral 12 denotes a line-shaped burner unit integrated with the mixing tube 11, which burns the mixed gas from the mixing tube 11 and detects a combustion state of the burner unit 12 in the vicinity thereof.
Is arranged.

Numeral 14 denotes a combustion tube for guiding the combustion gas from the burner section 12 upward, and a blower 15 for taking in and sending out the indoor air flow is disposed at the back of the combustion tube. A duct 16 mixes the combustion gas from the combustion tube 14 with the indoor air flow from the blower 15 to generate hot air.

[0007] As shown in FIG.
A control unit for driving and controlling the heater 8, the blower 15, and the like, which is determined in advance based on an operation condition signal input from the operation unit 18, an output of the oil level detecting unit 4 and the output of the combustion sensor 13, and an output of the temperature detecting unit 9 and the like. The control is performed in such a sequence that the operation condition of the burner unit 12 is displayed on the display unit 19.

In the above configuration, the vaporizing section 7 is kept at a predetermined temperature or higher by the heating control of the heater 8 by the temperature detecting means 9, and vaporizes the fuel supplied from the pump 5 through the oil supply pipe 6. The vaporized fuel gas is supplied to the vaporizing section 7.
The surrounding air is ejected from the nozzle portion 10 at the tip, and the surrounding air is sucked and mixed by the ejector effect, and the mixed gas is supplied into the burner portion 12 through the mixing pipe 11, and is ejected from the flame hole portion to burn. Is done.

The generated combustion gas is guided upward by a combustion tube 14 disposed so as to cover the periphery of the burner portion 12, and mixed with a room air flow from a blower 15 by a duct 16 covering the combustion tube 14. It is discharged as warm air and used for heating. Then, the control unit 17 changes the driving frequency and applied voltage of the pump 5 based on an operation condition signal input from the operation unit 18 in comparison with the ambient air temperature to control the fuel supply amount. As the primary air volume increases or decreases, the amount of combustion can be changed while maintaining a constant fuel-to-air ratio.

When the amount of fuel in the cartridge tank 3 is reduced due to the use of the fuel in the cartridge tank 3 and the weight in the cartridge tank 3 is reduced, the control unit 17 detects that the amount of oil in the cartridge tank 3 is reduced by the weight. The means 4A detects and causes the display unit 19 to display a first oil-out indication. Then, when the fuel is further used and becomes low and the oil level in the tank 2 becomes low, the oil level detecting means 4 detects the oil level and displays the second oil level on the display unit 19. The combustion in the burner section 12 is stopped after a predetermined time has elapsed so that the combustion is stopped before the fuel in the tank 2 runs out and the pump 5 cannot send the fuel. When the combustion of the burner unit 12 causes an abnormality for some reason, for example, when the combustion amount becomes extremely small, the control unit 17 stops the combustion by detecting the abnormality by the combustion sensor 13 and stops the combustion. , The display section 19 is adapted to display a display in accordance with the details of the combustion abnormality.

[0011]

However, in the oil warm air heater having such a configuration, the fuel in the tank 2 is used less and the oil level in the tank 2 is reduced, so that the oil level is reduced. After the surface detecting means 4 detects and causes the display unit 19 to display a running out of oil, the fuel in the tank 2 runs out and the pump 5
The combustion of the burner unit 12 is stopped after a predetermined time elapses so as to stop the combustion before the fuel can no longer be sent, but the operating condition signal input from the operation unit 18 is compared with the ambient temperature. If the fuel supply amount is adjusted by changing the drive frequency or applied voltage of the pump 5 based on the above, the combustible time fluctuates due to the change in the amount of fuel used in the tank, causing confusion for the user. There was a problem of inviting.

For this reason, if the above-mentioned predetermined time is set in accordance with the maximum combustion time so that the fuel does not run out within the predetermined time, the fuel is usually burned at various combustion amounts, for example, the combustion amount is minimized. In such a case, there is a problem that the combustible time becomes extremely short. The oil level detecting means 4 detects the level of the oil level in the tank, and the display unit 19
After the second out-of-oil indication, the method of fixing the amount of combustion, for example, if the amount of combustion is fixed to a minimum so that the combustion can be performed for a long time, there is a problem that the feeling of heating is impaired when it is cold. .

Further, a method has been considered in which the combustible time is displayed after the oil level detecting means 4 detects the oil level in the tank. To avoid confusion to the user, the combustible time should be set according to the maximum combustion,
Alternatively, there is only a method of fixing the amount of combustion, and it has been considered that the same problem as described above occurs.

The present invention solves the above-mentioned problems, and displays the remaining amount of fuel in the tank after the oil level detecting means 4 detects that the oil level has run out. By setting the amount of combustion and displaying it according to it, the user can clearly know how much fuel is left in the tank by time or volume and know it clearly, and it is easy to use without impairing the feeling of heating It is intended to improve.

[0015]

Since the value is set as the minimum combustion when the remaining combustion time becomes the maximum, if the user does not set, the maximum remaining combustion time is obtained, the feeling of heating is impaired, and the user burns with the remaining combustion amount setting means. Only when the setting is changed, the remaining combustion time is shortened, so that there is no fear that the fuel is heated too much by mistake, the combustion time after refueling is detected is increased, and the usability is further improved.

According to the invention of claim 8, after the refueling is detected,
Since the display of the operation display means of the display unit is switched as the refueling detection notification means, the operation state of the device can be confirmed on one display unit, and the user does not need to look at various places on the display unit. Visibility improves,
Since only one display can be made, the configuration is also simplified.

According to the ninth aspect of the present invention, the oil-out notification means is operated after the refueling is detected, so that the user is alerted to the operation after the refueling is detected, and the display of the refueling detection-notification means indicates the refueling. The user can be clearly notified of the display after the detection, and the user can prevent the display during combustion and erroneous recognition, thereby improving usability.
