Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a warm air heater.

[0002]

2. Description of the Related Art A conventional hot air heater is capable of performing a strong operation for a certain period of time (for example, 3 minutes) from ignition regardless of the room temperature at the start of heating operation, or by changing the wind direction plate or the air volume to improve the heat collecting property. It was improving.

[0003]

However, with this operation control, the temperature of the air in the room may not rise easily only with the heat quantity of the strong operation, which is remarkable especially when the temperature is low in the middle of winter. there were. In addition, even if the temperature of the air in the room rises, there is the problem that real comfort cannot be obtained until the temperature of the load on the floor, walls, windows, etc., rises. In response, the heating output can be changed from strong (3,200 kcal / h) to medium (2,500 kcal / h),
Even if it is controlled to weak (1,800 kcal / h) and fine (1,100 kcal / h), there is a drawback that the discomfort cannot be removed unless the temperature of the floor, walls, windows, etc. of the room rises sufficiently. there were.

[0004]

The present invention has been made to solve the above-mentioned problems, and a hot air heater in which the heating output of a heating element is controlled based on room temperature information detected by a temperature detecting means. In the case where the room temperature detected by the temperature detecting means is below a predetermined value, the heating element is started to operate with a special maximum output larger than the maximum output in the steady state, and then a certain period of time has passed or the room temperature reaches The warm air heater is configured to include control means for controlling the heating element to return to the steady heating output when either of the values reached is satisfied.

[0005]

With this structure, when the room temperature detected by the temperature detecting means is equal to or lower than the predetermined value, the heating element is started to operate with a special maximum output larger than the maximum output during steady state, and thereafter. When either a fixed time has elapsed or the room temperature has reached a predetermined value, the output is returned to a steady output and controlled.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

In each figure, 1 is a thermistor as a temperature detecting means for detecting room temperature and outputting room temperature information,
Reference numeral 2 is a microcomputer as a control means, and 3 is a heating element such as a kerosene burner, a gas burner or an electric heater for generating warm air.

In this configuration, the microcomputer 2 operates only once at the beginning of the operation, and only when the room temperature detected by the thermistor 1 is equal to or lower than the predetermined value, the microcomputer 2 operates for a certain period of time from the start of the heating operation. Alternatively, when the thermistor 1 detects a predetermined room temperature within the fixed time, the heating element 3 is operated and controlled with a special maximum output larger than the maximum output in the steady state only until that time. That is, the operation at the special maximum output is performed until either a certain time has elapsed from the start of operation or the room temperature reaches a predetermined value, and when either one is satisfied, the heating element The output is controlled by returning it to the steady heating output.

Specifically, as shown in the flow chart of FIG. 1, if the room temperature detected by the thermistor 1 is 5 ° C., which is a predetermined value or less, such as 10 ° C. at the beginning of the heating operation, the heating operation is started. To the thermistor 1 for a fixed period of time, for example, 15 minutes or 15 minutes.
When the room temperature of 10 ℃ is detected, until then, the heating element 3 has a special maximum output that is larger than the maximum output in the steady state. For example, if the steady output of the heating element is 3,200 kcal / h, 2
In case of 0% increase of 3,840 kcal / h, it has to be considered that it is not suitable for unlimited continuous operation due to the life of the heating element, and only once at the start of operation,
The heating element 3 is operated and controlled.

Since the construction of the embodiment is such, the temperature rise rate of the room temperature is accelerated, and thereby the temperature rise of the load on the floor, walls, windows, etc. of the room is also relatively accelerated, which is effective for realizing the heating comfort. I was able to give

[0011]

As described above, according to the present invention, it was possible to realize a warm air heater that quickly achieves comfortable heating without impairing safety.
