Description

[0001]
[Industrial application fields]
The present invention relates to the incorporation of an ion generator that generates negative ions into an air conditioner or an air purifier.
[0002]
[Prior art]
Conventionally, it has been known that negative ions have a good effect on the human body, and it is used for improving physiological action and medical therapy.
In addition, as shown in Japanese Patent Publication No. 7-23777 as an example of the prior art, an ion generator that is incorporated in an air conditioner generates negative ions and positive ions alternately, and the amount of negative ions in the room is provided by an ion sensor. I was adjusting.
[0003]
[Problems to be solved by the invention]
Such a conventional air conditioner is equipped with an expensive ion sensor, and there is a problem of high costs associated with the ion sensor and the mounting structure.
Also, negative ions cannot be directly felt by humans, unlike temperature and wind, so the negative ion generation status was unknown to the user.
[0004]
[Means for solving problems]
This invention pays attention to this point, and in order to solve the above-mentioned drawbacks, in particular, the configuration is provided with a high voltage generating circuit and a blower fan in the casing, and is used for generating ions in the air passage from the suction port to the air outlet or in the vicinity of the air passage. In the case where the radiation electrode is provided, a plurality of ion lamps for displaying the generation state of ions are provided on the surface of the casing, the blower fan has a plurality of rotation ranges, a constant is provided for each rotation range, and an operation time and The number of ions generated is increased or decreased according to the product of the constants, and the amount of ions generated is displayed.
[0005]
[Action]
If the operation switch (not shown) of the operation unit 22 is turned on in ST1, the air conditioner starts operation, and the compressor (not shown) and the fan 9 are started.
Next, in ST2, the rotation of the fan 9 is confirmed. If the fan 9 is rotating, the process proceeds to ST3, and if it is stopped, the process proceeds to ST12.
In ST3, a timer in the control device 21 is started, a constant X corresponding to the current air volume is selected in ST4, a product Y of the constant X selected in ST5 and the time measured by the timer is obtained, and ST6 The calculation is continued until the product Y reaches 24.
[0006]
Next, when the product Y at ST6 reaches 24 and proceeds to ST7, the maximum lighting number K of the ion lamp 20 corresponding to the current air volume is read, and the current lighting number P and maximum lighting number K of the ion lamp 20 are read at ST8. In comparison, if the current lighting number P is smaller than the maximum lighting number K, the lighting number P is increased by 1 in ST9. If the lighting number P is larger than the maximum lighting number K, the lighting number P up to the maximum lighting number K in ST11. , The timer is reset in ST10 and the process returns to ST2.
[0007]
If the fan 9 is stopped in ST2, it is determined in ST12 and ST13 whether the stop of the fan 9 is related to the defrosting operation of the dry operation or the heating operation. When all the lamps 20 are extinguished and the dry operation and the heating operation are being performed, the number P of the ion lamps 20 is not changed until the fan 9 restarts the operation.
Since the display using the ion lamp 20 is performed, the current amount of ions in the room can be easily and easily displayed to the user without using an expensive ion sensor.
