Abstract

PURPOSE:To provide a hot air heater which can achieve quickly a comfortable heating without damaging safety CONSTITUTION:A hot air heater is constituted of a heat generator 3 which generates hot air, a thermister 1 which detects room temperature and outputs room temperature information and a microcomputer 2 which determines whether the heat generator 3 is started to operate in an initial operation at a special maximum output which is larger than its normal time maximum output, based on the room temperature detected by the thermister 1, and if it determines that the heat generator 3 should be started to operate at the special maximum output, it also controls the operation time and the number of the operation times.

Description

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 with only the heat quantity of strong operation, which is remarkable especially when the temperature is low in midwinter. 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 minute (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 includes a heating element for generating warm air, and a temperature detecting means for detecting room temperature and outputting room temperature information. Then, based on the room temperature detected by the temperature detecting means at the beginning of the heating operation, it is determined whether or not to start the heating element with a special maximum output larger than the maximum output in the steady state. When determined, the hot air heater is configured with a control unit that controls the operating time and the number of times of operation.

[0005]

In this structure, the control means detects the room temperature by the temperature detection means at the beginning of the heating operation, and based on the result, starts the operation of the heating element with a special maximum output which is larger than the maximum output in the steady state. Whether or not, and when the operation start by the special maximum output is determined, the operation time and the number of times of operation are determined, and the heating element is controlled accordingly.

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 which is a control means, and 3 is a heating element such as a kerosene burner, a gas burner or an electric heater which generates hot 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 a predetermined value, a predetermined time from the start of the heating operation, or When the thermistor 1 detects a predetermined room temperature within the fixed time, the heating element 3 is controlled to operate at a special maximum output that is larger than the maximum output in the steady state only until that time.

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 ° C is detected, the maximum output of the heating element 3 is larger than the maximum output in the steady state until then, for example, if the steady output of the heating element is 3,200 kcal / h, 1
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.

That is, when the room temperature detected by the temperature detecting means is below a predetermined value at the beginning of the heating operation, the heating element is started with a special maximum output that is larger than the maximum output in the steady state, and the operation is performed. The time and the number of operations were controlled.

Since the constitution of the embodiment is such, the temperature rise rate of the room temperature is accelerated, and thereby the temperature rise of the load of 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

[0012]

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