BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a petroleum fuel combustion apparatus for burning petroleum fuel.

[0002]

2. Description of the Related Art FIG. 7 is a block diagram showing a configuration of a conventional oil fan heater. Kerosene 52, which is a petroleum fuel for combustion, is stored in the fuel tank 51. Above the fuel tank 51, a refueling tank 53 is provided detachably, and the kerosene in the refueling tank 53 is automatically supplied according to the remaining amount of kerosene in the fuel tank 51. The fuel tank 51 is provided with an oil feed pump 54. The oil feed pump 54 sucks up the kerosene 52 in the fuel tank 51 and sends the oil to a vaporizer 56 via an oil feed pipe 55. Vaporizer 56
Then, the kerosene 52 is vaporized by the vaporizing element 57. This vaporized gas is ejected by a nozzle 58 to a burner 59 and is burned by the burner 59. In addition, the vaporized gas is burner 5
A solenoid 58 is provided on the nozzle 58 that ejects the nozzle 9 to open and close the nozzle port. Also the fuel tank 51
The inside is provided with a filter for removing moisture, altered kerosene, impure kerosene, etc. contained in kerosene. The filter is a fuel supply port (6) from the fuel tank 53 to the fuel tank.
1) Or, it is arranged at one of the suction ports (62) of the oil supply pump, or both.

[0003] In the oil fan heater configured as described above, when a power switch provided on the operation section of the oil fan heater body is operated, the oil feed pump 54 operates and the kerosene 52 in the fuel tank 51 is discharged. The oil is sent to the vaporizer 56. Almost simultaneously with this, the solenoid 60 is turned on, and the fuel gas vaporized in the vaporizer 56 is ejected to the burner 59 by the nozzle 58 and burned. When the fire is extinguished, the operation of the power switch (extinguishment operation) stops the oil supply pump 54 and then stops the gas injection by the nozzle 58 at time t ₁ later because unburned gas remains in the vaporizer 56. This is to prevent If the unburned gas remains in the vaporizer 56, the gas is released to the outside after the operation of the apparatus is stopped to generate odor. FIG. 8 is a time chart showing an operation procedure at the time of fire extinguishing.

[0004] The oil feed pump 54 adjusts the amount of kerosene sucked up according to the required amount of combustion. The required combustion amount is calculated based on the difference between the current room temperature and the target temperature. The current room temperature is detected by the sensor, and the target temperature is appropriately set by the user. In the conventional setting of the target temperature, a "lower button" and a "higher button" are provided on the operation unit, and the target temperature is changed in accordance with the number of times these buttons are pressed or the length of time the buttons are kept pressed. FIG. 9 is a flowchart showing a conventional procedure for setting a target temperature. When changing the target temperature, the first “lower button”
Alternatively, the mode is switched to the target temperature setting mode by pressing the “up button” (n11 → n12 → n13, n1).
4). When the “raise button” is pressed in the target temperature setting mode, the target temperature is raised by one level each time the button is pressed or the button is kept pressed for a certain time (n15 → n18 or n16 → n17 → n1).
8).

When the "lower button" is pressed in the target temperature setting mode, the target temperature is lowered by one level each time the button is pressed or each time the button is kept pressed for a certain time (n19 → n22 or n19 → n22). n20 → n
21 → n22). In this way, the target temperature is sequentially changed, and the target temperature setting mode is canceled unless the “up button” or “down button” is pressed for a predetermined time (n23 → n24).

EXAMPLES 1, 2, a diagram showing an embodiment of FIG. 3 Yoko devised, 1 is a fragmentary block diagram of the oil fan heater, a processing procedure of FIG. 2 is the target temperature setting process FIG. 3 is a flowchart showing the setting stage of the provisional target temperature.

The oil fan heater is controlled by the controller 1. The controller 1 has an area M1 for storing a target temperature, an area M2 for storing a provisional target temperature, and an area M3 for storing a detected room temperature. An operation unit having a temperature setting start button 2, a temperature setting end button 3, and a temperature display unit 4 is provided at an upper portion of the oil fan heater main body. The temperature setting start button 2 and the like are connected to the controller 1. The oil fan heater main body is provided with a room temperature sensor 5, and the temperature in the room where the oil fan heater is installed is detected and input to the controller 1. Further, the controller 1 controls the oil feed pump 6 so that the amount of kerosene sucked up is controlled. The controller 1 compares the room temperature (M3) detected by the room temperature sensor 5 with the target temperature (M1), and sets the suction amount of the oil feed pump 6 according to the difference. For example, when the room temperature is significantly lower than the target temperature, the siphoning amount is increased, and when the room temperature approaches the target temperature or when the room temperature exceeds the target temperature, the siphoning amount is set small.

The procedure for setting the target temperature which is the basis of the suction amount control will be described with reference to FIGS. When a temperature setting start button 2 provided on the operation unit is pressed, a setting mode is set, and a temperature setting mode is entered (n1).
→ n2 → n3). In the setting mode, first, the current target temperature stored in M1 is set in M2 as a temporary target temperature (n4). Then, the temporary target temperature is changed stepwise until the temperature setting end button 3 is pressed (n5 → n).
6). For example, as shown in FIG. 3, the temperature is changed in steps of 1 ° C., and when the temperature reaches the set upper limit temperature, the temperature is changed while returning to the set lower limit temperature. The provisional target temperature is displayed on the temperature display section 4, and the user may press the temperature setting end button 3 when the provisional target temperature reaches the desired set temperature. When the temperature setting end button 3 is pressed, the temperature of the temporary target temperature storage area n2 at that time is stored in the target temperature storage area M.
Then, it is set to the target temperature (n7). After the target temperature is set in this way, the setting mode is canceled (n8). The interval of the change when the provisional target temperature is changed stepwise is set to about one second to several seconds.

FIG . 4 is a time chart showing an operation procedure of the oil feed pump and the nozzle solenoid when the oil fan heater is consumed. When the power switch provided on the operation unit is operated during the combustion of the oil fan heater, the digestion operation is started. When the power switch is turned off, the amount of fuel supplied by the oil pump gradually decreases. Accordingly, the amount of gas vaporized by the vaporizer decreases. During this time, the nozzle is in the open state, and the vaporized gas in the vaporizer is ejected to the burner and burned. However, as described above, the amount of gas to be vaporized is gradually reduced, so that the combustion flame is weakened. Then, after the power switch is turned off, t
_Two hours later, the oil pump is completely stopped, and then the solenoid is turned off and the vaporized gas ejection nozzle is closed. At this time, the vaporized gas is almost completely burned, and the unburned gas odor after the combustion is stopped is remarkably reduced.
