Description

TECHNICAL FIELD The present invention relates to a combustion amount control method for a heating machine and a combustion amount control device for a heating machine, and in particular, vaporization before the combustion amount of kerosene reaches a target value. TECHNICAL FIELD The present invention relates to a combustion amount control method for a heater and a combustion amount control device for a heater to control the combustion amount so that the temperature of the heater becomes a temperature corresponding to a target value.

<Prior Art> With an oil fan heater, the room temperature is controlled by comparing the temperature inside the room with the temperature set for the equipment (hereinafter referred to as the room temperature target temperature) and changing the combustion amount of kerosene. There is.

In this case, it was necessary to control the temperature of the carburetor at a temperature corresponding to the burning amount of kerosene.

Therefore, conventionally, there is no particular problem when reducing the burning amount of kerosene, but when increasing the burning amount of kerosene, it was necessary to raise the temperature of the carburetor before increasing the burning amount. This is because when the kerosene combustion amount is suddenly increased when the temperature corresponds to the state where the kerosene combustion amount is low (when the vaporizer temperature is low), the flame condition deteriorates and soot and carbon monoxide are generated. Because it does.

FIG. 3 is a flow chart of conventional control, and FIG. 4 is a block diagram of a conventional control device.

In FIG. 4, the measurement results of the room temperature measuring device 10 and the room temperature target setting device 20 are given to the combustion amount setting device 30, and the combustion amount setting device 30
Sets the amount of combustion based on the difference between these two measurements,
This is given to the vaporizer temperature controller 60.

On the other hand, the temperature of the carburetor is actually measured by the carburetor temperature measuring device 50, and the result is given to the carburetor temperature controller 60. The carburetor temperature controller 60 instructs the combustion amount change indicator 40 to change the combustion amount based on the result.

That is, according to FIG. 3, the room temperature and the room temperature target temperature are compared, and if there is a difference, it is judged whether or not the combustion amount is to be reduced, and if the combustion amount is to be reduced, the step becomes END.

However, when it is necessary to increase the amount of combustion, distinguish it by the amount of combustion, and in any case, increase the amount of kerosene by stepping so that the temperature of the carburetor reaches an appropriate temperature. I was taking the way.

<Problems to be Solved by the Invention> When the combustion amount of kerosene is changed as described above, first, it is distinguished whether the combustion amount is increased or decreased, and when it is further increased, it is actually increased. Before, it was necessary to constantly check whether or not the temperature of the carburetor reached the temperature corresponding to the target combustion amount, and therefore the control of the combustion amount was complicated.

The present invention was devised in view of the above circumstances, and an object thereof is to provide a combustion amount control method for a heater and a combustion amount control device for a heater that do not require complicated control.

<Means for Solving the Problem> A combustion amount control method for a heater according to the present invention determines a target combustion amount based on a result of comparison between room temperature and a room temperature target temperature, and the target combustion amount is the current value. When the combustion amount does not match, if the combustion amount is to be increased, the combustion amount is gradually increased from the current combustion amount to match the target combustion amount, and if the combustion amount is decreased, the current combustion amount is reduced. The combustion amount is gradually reduced from the combustion amount so as to match the target combustion amount.

Further, the combustion amount control device of the heating apparatus according to the present invention, the room temperature measuring device, the room temperature target setting device, the difference between the room temperature measured by the room temperature measuring device and the target room temperature set by the room temperature target setting device. It has a combustion amount determiner for determining the combustion amount on the basis of the combustion amount, and a combustion amount change indicator for instructing the combustion amount to be changed stepwise from the current combustion amount according to the result of the fuel amount determiner.

<Operation> When changing the amount of combustion, do not change it all at once
The amount of combustion is increased or decreased in stages.

Embodiment An embodiment according to the present invention will be described below with reference to the drawings. FIG. 1 is a flow chart of the present invention, and FIG. 2 is an apparatus according to the present invention. The method of the present invention will be described with reference to FIG.

First, the room temperature and the room temperature target temperature are compared to determine the target combustion amount.

Next, compare the combustion amount determined in with the current combustion amount,
If they match, there is no increase or decrease in the amount of combustion, so END as it is.

When increasing the combustion amount, the combustion amount of kerosene is increased by 1 unit.

The combustion amount increased by 1 unit is compared with the target combustion amount, and if it is still insufficient, it is further increased by 1 unit. Repeat this. That is, the current combustion amount is gradually increased toward the target combustion amount. And if both match, END.

′ When reducing the amount of combustion, decrease the amount of combustion of kerosene by one unit.

If the combustion amount reduced by 1 unit is still larger than the target combustion amount, the combustion amount is further decreased by 1 unit. Repeat this. That is, the current combustion amount is gradually increased toward the target combustion amount. And if both match, END.

Therefore, according to the present invention, unlike the conventional method, it is not necessary to constantly check the temperature of the carburetor, which is simple.

In FIG. 2, the measurement results of the room temperature measuring device 10 and the room temperature target setting device 20 are given to the combustion amount setting device 30, and the combustion amount setting device 30
Determines the amount of combustion based on the difference between these two settings,
This is given to the combustion amount change indicator 40.

On the other hand, separately from the route, the temperature of the carburetor is actually measured by the carburetor temperature setting device 50, and the result is given to the carburetor temperature controller 60. According to this device, it is not necessary to provide the carburetor temperature controller with the measurement result of the combustion amount setter 30.

<Effects of the Invention> According to the combustion amount control method for a heater and the combustion amount control device for a heater according to the present invention, the target combustion amount is determined based on the result of comparison between the room temperature and the room temperature target temperature, and the target When the amount of combustion of No. does not match the current amount of combustion, when changing the amount of combustion of kerosene or the like, the amount of combustion is increased or decreased stepwise without making a large amount of change at once. Therefore, for example, by setting the stepwise change amount of the combustion amount that changes stepwise as an appropriate change amount according to the change amount of the temperature of the carburetor, the carburetor can be set before the combustion amount reaches the target combustion amount. Since the temperature of 1 is a temperature corresponding to the target value, it is not necessary to check the temperature of the carburetor, and the combustion amount control becomes easier than the conventional method and apparatus.
