Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a radiant heater that uses heat rays, a fan,
The present invention relates to a swinging device suitable for a warm air blower.

[Prior Art] Recently, a large number of electric heaters of the heat ray radiating type using a quartz tube heater are equipped with a swinging device, and this configuration is for driving the entire upper frame body to which the heat ray generating portion is attached. There is one that is operated by the motor, or that the heat ray generating part is fixed and only the reflector part is rotated by the driving motor.

In addition, this swing mechanism has traditionally been attached to fans and cold / warm fans, and a fan that swings the entire fan fan with a motor or a fan that fixes the fan to the louver is driven by a motor. There is a cold / hot air fan to operate, and it is functionally the same whether it is a heat radiation type heater or a fan or cold / hot air fan.

Then, in order to use a driving motor, there is an additional function that allows the swing angle and swing speed to be changed.

[Problems to be Solved by the Invention] By the way, when operating the swinging device, it is rare that a heating wire for heating or cold / warm air is required for the entire swinging angle, and most of them are 2-3 It is mostly used by a small number of people. For this reason, heat rays for heating and cold / hot air are also sent to places where they are not needed, and there is a lot of waste, which is a problem with high energy costs such as electric heaters of the heat ray radiation type. No measures have been taken in this regard.

[Means for Solving the Problem] The present invention solves the above-mentioned problems. A motor 1 for swinging or driving a louver is attached to a frame body A of an apparatus, and the motor 1 generates a heat ray. The radiation direction or the blowing direction of the cold / warm air is changed in a certain range, and the frame A is provided with a sensor 4 for detecting the swing direction, and in a specific direction detected by the sensor 4 during the swing operation, In the swinging device that concentrates heat rays or cold / warm air, the sensor 4 is composed of an object detector of a person / object separated from the frame A, and when the sensor 4 faces a specific direction detected by the sensor 4, The number of rotations is reduced to concentrate the heat rays or cold / warm air in a specific direction.

Further, as a detection mechanism of the sensor 4 in a specific direction, the sensor 4 can be attached to the upper frame body 2 that swings or the louver 3 that swings to lower the rotation speed of the motor 1 near the maximum detection output of the sensor 4. It can be implemented with a simple structure.

[Operation] The structure and operation of the swing mechanism are the same as those of the conventional product, and the rotation of the driving motor 1 is changed to the swing motion by the crank to rotate the upper frame body 2 or swing the louver 3. Is. For this reason, in the heat ray radiating heater or the cool / warm air blower, when the driving motor 1 is energized, the heat ray radiating direction and the cold / warm air blowing direction can be swung.

The sensor 4 attached to the frame A is a person separated from the frame A.
It is composed of object detectors, and it monitors the direction of people / objects that require heat rays or cold / warm air near the frame A.
When the sensor 4 detects the specific direction, the rotation speed of the motor 1 decreases when the sensor 4 swings in the specific direction. Therefore, the swinging motion is slowly performed in the specific direction to prevent heat rays and cold / warm air. It was possible to send in a concentrated manner.

In addition, the upper frame 2 that swings and the louver 3 that swings
By attaching the sensor 4 to the, the object detector can be used as a simple type that monitors only the front side, and the swinging motion can easily identify the direction of the person / object that requires heat rays or cold / hot air. It became so.

If a person needs heat rays or cold / warm air, far infrared rays are generated. Therefore, if the object detector of the sensor 4 is an infrared light detector, heat rays, cold / warm It is easy to identify the direction of the person who needs the wind.

Furthermore, if it is an object that requires heat rays or cold / warm air, it is rare that far infrared rays that can be detected from an object are generated, and the swinging device is a heat ray radiation type heater. For example, the infrared light detector can be used as the object detector of the sensor 4 by the reflected light or by placing a portable infrared light generator near the object in the case of a cold / hot air blower.

In addition, the sensor 4 is an ultrasonic oscillator 7 attached to the frame 1.
And an ultrasonic wave receiver 8, the ultrasonic wave receiver 8 detects a specific direction by reflected ultrasonic waves from a person or object in the vicinity of the frame A. If there is an object in the object, it can detect it and perform a swinging motion slowly to concentrate and send hot rays or cold / warm air.

Therefore, when the swinging angle is directed in a specific direction, the swinging motor 1 is rotated at a low speed and slowly swings, so that hot rays and cold air are concentrated and sent in a required direction. The driving motor 1 rotates at a high speed in a direction other than the specific direction, and the swinging motion is swiftly performed in the direction that does not require heat rays or cold air.

[Embodiment] The present invention is required by increasing the swinging speed in the direction of a person / object requiring heat rays or cold / hot air, and slowing the swinging speed in the direction of no person / object. In order to send heat rays for heating and cold / warm air mainly, 1 is a motor for swing drive attached to the frame A, 2 is an upper frame body that is movable by the motor 1 for swing drive, Reference numeral 3 is a louver that swings in the blowing direction of cold / warm air.

Reference numeral 4 denotes a sensor composed of an object detector that detects an object near the frame A. The sensor 4 monitors a direction that requires heat rays or cold / warm air, and when it detects a specific direction, it rotates at high speed. The rotation of the driving motor 1 is switched to low rotation. Therefore, when it turned to a specific direction, it was possible to perform a swinging motion slowly, and to send the heat rays and cold / warm air in a concentrated manner.

At this time, if the sensor 4 is attached to the upper frame 2 and the louver 3 that are movable by the driving motor 1, the sensor 4 may be a simple type that monitors only the front direction, and the sensor 4 detects in the direction in which the sensor 4 faces. When the output is maximized, it can be known that this direction is a specific direction that requires heat rays or cold / hot air.

If a person needs heat rays or cold / warm air, heat rays are radiated from the human body, so a well-known infrared light detector can be used as the object detector of the sensor 4. Therefore, there is a person in the direction showing the maximum value of the output of the infrared light detector, and the specific direction can be easily detected.

Numeral 5 is a portable infrared light generator which is arranged near an object that requires heat rays or cold / hot air. If the object is an object, it does not generate heat rays like the human body, so it is a portable infrared light generator. By generating infrared light of a specific wavelength from 5, it was possible to specify the direction of an object that requires heat rays or cold / warm air in combination with the infrared light detector that constitutes the sensor 4.

Further, when the device to which the swinging device is attached is a heat radiation type heater using a quartz tube or the like, a portable reflection plate 6 may be used instead of the portable infrared light generator 5, and a sensor may be used. The infrared photodetector constituting No. 4 is capable of specifying the direction of an object requiring this heat ray by the reflected heat ray for heating.

Reference numeral 7 is an ultrasonic oscillator attached to the frame A, 8 is an ultrasonic receiver, and the sensor 4 may be composed of an exploration-type detection unit composed of the ultrasonic oscillator 7 and the ultrasonic receiver 8. ,
The ultrasonic receiver 8 detects a specific direction by reflected ultrasonic waves from a person or an object near the frame A.

The block diagram of FIG. 3 shows an embodiment of the exploration-type detector.
Reference numeral 9 is a time difference detector that receives the timing of emitting the pulsed ultrasonic wave emitted from the ultrasonic oscillator 7 and the timing of receiving the pulsed ultrasonic wave received by the ultrasonic wave receiver 8 as reflected by an object. The distance between the frame A and the object can be known from the received time difference. Reference numeral 10 is an averaging circuit for the time difference level, and it is possible to know the average distance between the frame A and a person, object, wall or the like in the swing range.

Reference numeral 11 is a comparison circuit for comparing the distance signal of the time difference detector 9 and the distance signal of the averaging circuit 10, and from the emitting direction of the ultrasonic oscillator 7 when the signal of the time difference detector 9 becomes a short distance,
It is possible to identify the direction of people and objects that require heat rays or cold / hot air.

Reference numeral 12 is a motor switching circuit connected to the output of the comparison circuit 11, which slows the swinging speed in the direction of a person / object requiring heat rays or cold / hot air, and does not require heat rays or cold / hot air.・ In the direction of the object, the swing speed is increased.

In addition, since the radiation type electric heater using a heat pipe such as a quartz tube has excellent rising characteristics, the sensor 4 and the heating element for heating are interlocked to drive the driving motor 1 at a low speed when a specific direction is detected. While rotating, energize the heating element,
In other directions, if the power supply to the heating element is cut off, effective energy saving can be achieved.

[Effect] As described above, according to the present invention, the swinging motion is performed slowly while facing the person / object requiring the heat ray or the cold / warm air, and conversely, the heat ray or the cold / warm air is applied. Since the swinging motion is performed quickly while facing the direction that is not required, the time during which the hot wire or cold / warm air is directed in the required direction is longer than the time required for one swinging motion. And increased comfort.

And since the swinging motion is only aimed for a short time in the direction of people / objects that do not require heat rays or cold / hot air, there is no waste of energy, and an excellent energy saving effect is achieved. It was obtained.

The upper frame 2 that is movable as a mounting position of the sensor 4
When attached to the louver 3 or the louver 3, the sensor 4 is a simple type that monitors only the front direction, and can detect a specific direction with a simple configuration.

Also, when using the heat rays emitted from the human body for detection,
If the sensor 4 is composed of an infrared light detector, it is possible to know a specific direction with high accuracy with a simple device, and it is possible to use it near an object if it requires heat rays or cold / hot air. By disposing the portable infrared light generator 5 and the portable reflection plate 6, the specific direction can be easily detected by the infrared light detector.

On the other hand, although the sensor 4 is expensive, the one that knows a specific direction by using ultrasonic waves has good handleability and few malfunctions.
The range of selection of the sensor 4 is widened depending on the performance.
