Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a block circuit diagram in an embodiment of the present invention.

A commercial power source 1, an ultraviolet lamp 2, a photoelectron emitting material 3 covering the ultraviolet lamp 2, a lamp control means 4 for controlling the ultraviolet lamp 2, and further the photoelectron emitting material 3
Fan motor 5 which is a blowing means for sending negative winds generated when ultraviolet rays are emitted to it, a motor control means 6 for controlling the fan motor 5, and an infrared ray for detecting the movement of a person. A sensor 7, a dirt sensor 8 for detecting the dirt level of the air by detecting the amount of dust contained in the air, and an operation SW for performing a driving operation.
9, an ultraviolet sensor 10 for detecting the disconnection of the ultraviolet lamp 2, a display LED 11 which is a display means for displaying the generation state of negative ions, and a disconnection LED 12 which is a display means for displaying the disconnection of the ultraviolet lamp 2. Then
The control means, the sensor, the SW and the LED are all connected to the signal control means 13 and are configured to be controlled by the signal control means 13. The photoelectron emission material 3 is made of any one of brass, bronze, and phosphor bronze.

Next, the operation of the ion generator will be described with reference to FIG.

After turning on the power, the ultraviolet lamp is turned on.
Since the fan motor 5 is not operated until the operation SW 9 is operated, the negative ions are only floating around the photoelectron emitting material 3, and the amount (generated amount) that goes out of the device is very small. When the operation SW 9 is operated, the fan motor 5 is operated, and by blowing air to the photoelectron emission material 3, negative ions floating around the photoelectron emission material 3 are blown out of the device, so that the operation is started. Directly, a large amount of negative ions will be generated. During operation, the signal control means 13 controls the rotation speed of the fan motor 5 so that the air volume becomes a fluctuation pattern of 1 / f. The ON time of the UV lamp is 15 minutes, 10 minutes, 5 as shown in the figure.
Minutes ... gradually shorter, and conversely the OFF time is 5 minutes, 10 minutes, 2
The signal control means 13 controls so as to gradually increase to 0 minutes. Further, the signal control means 13 constantly monitors the infrared sensor 7 for more human movement, and at the same time, monitors the dirt sensor 8 for whether the air is dirty or not. After detecting the movement of the person or the dirt of the air after the state of no movement of the person continues, the ultraviolet lamp 2 is turned on again for 15 minutes. While the ultraviolet lamp 2 is ON, the display LED 11 is turned on while changing the brightness according to the fluctuation of the air volume, and when the signal control means 13 detects the disconnection of the ultraviolet lamp 2 by the ultraviolet sensor 10, the disconnection LED 12 is turned on. Turn on the light. When the ultraviolet lamp 2 is turned on, the ultraviolet lamp 2 is preheated by always supplying a small current to the ultraviolet lamp 2 for 5 seconds.

The operation of the above configuration is as follows.

Since the negative ions are blown by the motor fan 5, the negative ions can be spread over a wide range, and the 1 / f fluctuation pattern is generated, so that a negative ion state close to a natural state can be realized. It is possible to obtain higher relaxation effect. Moreover, since a large amount of negative ions are generated at the start of operation, it is possible for the user to notice the effect of negative ions more significantly. Further, since the infrared lamp 7 and the dirt sensor 8 are monitored to judge whether the ultraviolet lamp 2 is turned on for a long time, the ratio of the time when the ultraviolet lamp 2 is turned on becomes long when there is no person nearby.
When a person is not near, the ratio of the time when the ultraviolet lamp 2 is turned on is shortened, so that it is possible to extend the life of the ultraviolet lamp while securing the relaxing effect of negative ions on the user, and at the same time.
Since the OFF sensations are unequal intervals, the user is not "accustomed" to the negative ions, and the relaxing effect of the negative ions continues without diminishing.
Further, since the display LED 11 is turned on while changing the brightness according to the fluctuation of the air volume, a visual relaxing effect is also obtained, and the disconnection L occurs when the ultraviolet lamp 2 is disconnected.
Since the ED 12 lights up and the user is informed of the replacement of the lamp, usability is also improved. The UV lamp 2 is turned on
The life of the ultraviolet lamp 2 can be further extended by providing a pre-heating time at the time of N.

In the present embodiment, the ultraviolet sensor 10 is used for detecting the disconnection of the ultraviolet lamp 2, but the current detecting means for detecting the current flowing through the ultraviolet lamp 2 or the temperature for detecting the temperature of the ultraviolet lamp 2 is used. It is obvious that the same effect can be obtained by using the sensor.

[0028]

According to the present invention, the life of the ultraviolet lamp is ensured, the "habituation" of the user is prevented, and the usability is improved, and the air conditioner using the same is used. Machine can be provided.
