DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid fuel-fired heater for heating by generating warm air in a room, and more particularly to a heating operation by judging a temperature distribution in a room and the presence or absence of a person. Is performed.

[0002]

2. Description of the Related Art Conventionally, a liquid fuel fired heater that heats a room with warm air is provided with a room temperature detecting element for detecting the temperature of the indoor air in a part of the body, and the value detected by the room temperature detecting element is reduced. The temperature and discharge amount of the hot air were adjusted based on this. Then, the room temperature detecting element is mounted on the back surface of the airframe or near the suction port of the blower to detect the temperature in the room. Further, the detection point of the indoor temperature is, for example, a point in the center of the room that is several tens of centimeters away from the floor surface, and the temperature at that point is controlled to be equal to the temperature set by the room temperature setting device.

[0003] However, the comfort of heating is greatly affected not only by the indoor air temperature but also by the level of the walls and floors. The method of controlling the operation cannot always maintain a comfortable heating state. For example, if the indoor air temperature has a certain value and the temperature of the indoor wall or floor is lower than the air temperature, the amount of radiant heat from the human body, which is the object to be heated, to the wall surface And the amount of radiant heat from the wall to the human body becomes large, so that a large difference occurs in the sense of warmth, and the warmer may feel insufficient warmth. If the wall temperature is higher than the air temperature, the opposite phenomenon may occur.

On the other hand, as disclosed in Japanese Utility Model Laid-Open No. 02-069247, not only the temperature of the indoor air but also the temperature of the indoor walls and floors, that is, the temperature of the objects constituting the indoor are detected, and the liquid fuel combustion heating is performed. There has been invented an apparatus in which the operation of the machine is controlled in accordance with the temperature difference between the two to make the feeling of warming comfortable.

[0005]

However, in the prior art disclosed in Japanese Utility Model Laid-Open No. 02-069247, although the point of focusing on the temperature of the wall surface is good, there is no room for selecting a detection target. Since the temperature is limited to one direction, if the temperature differs depending on places such as a floor or a wall at the time of heating, there is a problem that control is performed based on the deviated temperature information.

[0006]

Reference numeral 6 designates a burner 2 which allows air to flow into the main body 1 and
This is a blower fan that discharges warm air from the hot air outlet 5 into the room. Numeral 7 denotes a horizontal louver angle changing device for changing the vertical angle of the horizontal louvers 3, 3,..., Which employs an electric motor. Reference numeral 8 denotes a vertical louver angle changing device for changing the left and right angles of the vertical louver 4, which employs an electric motor similarly to the horizontal louver angle changing device 7.

Reference numeral 9 denotes an infrared sensor unit for detecting the presence or absence of a person and detecting the temperature of various places in the room. The infrared sensor unit 9 has a movable mechanism (not shown) that can move freely up, down, left and right. (Not shown). A central processing unit 10 controls the burner 2, the blower fan 6, the horizontal louver angle variable device 7, and the vertical louver angle variable device 8 based on the signal from the infrared sensor unit 9. .

Reference numeral 11 denotes an operation unit for operating the liquid fuel combustion heater.

In the liquid fuel-fired heater constructed as described above, when a desired temperature is first set by the operation unit 11 and the operation is started, the burner 2 and the blower fan 6 are energized and the hot air discharge port 5 is opened. Warm air is discharged indoors. Then, information on a part of the room detected by the infrared sensor unit 9, that is, the presence or absence of a person in the part and the temperature are input to the central processing unit 10,
Based on the information, the central processing unit 10 controls the calorific value of the burner 2 and the rotation speed of the blower fan 6, and also determines the angles of the horizontal louvers 3, 3,... Control.

For example, when the infrared sensor unit 9 determines that a person is present and the detected temperature does not reach the set temperature, the central processing unit 10 sets the detected temperature to reach the set temperature earlier. , The amount of heat generated by the burner 2 is set to an appropriate value, the number of revolutions of the blower fan 6 is set to an appropriate value, and the hot air is intensively blown to the location where the infrared sensor unit 9 detects the temperature. As shown, horizontal floor-3,

Next, when the infrared sensor unit 9 determines that a person is present and the detected temperature has reached the set temperature, the central processing unit 10 sets the infrared sensor unit 9 to a preset value. It is moved by a specified drive pattern to obtain information on a new location in the room.

If the infrared sensor unit 9 determines that there is no person, the central processing unit 10 moves the infrared sensor unit 9 by a specified driving pattern to determine whether or not a person exists in the entire room. When there is no person in the room, the operation mode is switched to the safety mode or the energy saving mode, and when there is a person, the above-described control is executed.

[0018]

As described above, according to the present invention, the presence / absence of a person in a room and the temperature of various places in the room are detected by an infrared sensor unit which can move up, down, left and right freely, and the heat of the burner is generated. In addition to adjusting the volume and the number of rotations of the blower fan, and adjusting the angles of the horizontal and vertical louvers, when nobody is present indoors, the operation mode for lowering the set temperature is executed. When there are people and the temperature is low when there are people, it is possible to blow the hot air intensively to the low temperature area and make the temperature of the entire room uniform. More comfortable and qualified heating.
