When the solenoid (23) is excited and the plunger (24) is attracted, the cylindrical cap (21) moves in the direction of the arrow in FIG. 2 and is held at the pull-out position (the state of FIG. 4 (b)). When the solenoid (23) is de-energized, the spring (25) urges it to move in the direction opposite to the arrow in FIG. 2 and hold it in the storage position (the state in FIG. 4 (a)). It The cylindrical cap 21 has small holes B (26) at the same intervals as the small holes A (17) in the axial direction and the circumferential direction of the distal end cylindrical portion (16). The cylindrical cap is installed
When the (21) is in the storage position, the small holes A (17) and the small holes B (26) are closed by the side walls of each other, but when the cylindrical cap (21) is in the insertion position, The small holes A (17) ... And the small holes B (26) are overlapped with each other so that the inside and outside of the tip cylindrical portion (16) communicate with each other, and the odor of the fragrance is released. The fragrance is replaced by pulling out the storage container (15) from the opening (20).

Now, such an air cleaner is controlled by a microcomputer, and the control mechanism of the air cleaner centering on the microcomputer (27) (hereinafter referred to as a microcomputer) will be described below with reference to FIG.

The microcomputer (27) includes a CPU (28), a RAM (29) and a ROM
(30), timer 31, system bus (32) and input / output port
It is composed of (33) to (36). The CPU (28) is a control unit (3
7) and an arithmetic unit (38), the control unit (37) fetches and executes instructions, the arithmetic unit (38) from the control unit (37) in the instruction execution stage. The arithmetic processing such as binary addition, logical operation, increase / decrease, and comparison is performed on the data given by the control signal from the input device or memory. The RAM (29) is for storing data related to the fan, and the ROM (30) stores means for operating the air cleaner in advance, setting conditions for judgment, and processing various information. The rules for doing so are loaded.

A signal from an input key circuit (39) composed of a power switch and other switches is input to the input port (33), and the output port (35) (36) includes a light emitting diode group (not shown). A control signal is sent to the LED drive circuit (40) and the load drive circuit (41) which are driven. The load drive circuit (41), according to the control signal from the microcomputer (27),
The blower motor (12) and the solenoid (23) are turned on and off. (42) is a power supply circuit for supplying a voltage to the microcomputer (27), and (43) is a reset signal generating circuit.

Thus, in the air cleaner (1), the blower fan (13) is rotated by the drive of the blower motor (12), and air is introduced into the dust collecting chamber (6) from the suction grille (4). Inhale. Then, the inhaled air has dust and odor removed by the dust collecting filter (9) and is again discharged from the blowout grill (3).

During this time, the microcomputer (27) accumulates the drive time of the blower motor (12) with the counter in the arithmetic unit (38), and the RA is updated while updating the accumulated time for each count.
Store in M (29). Since the stored contents of the RAM (29) are retained unless the power plug is unplugged from the outlet, the microcomputer (27) sets the drive time of the RAM (29) every time the blower motor (12) is driven. In addition, the time stored in () is added up. Thus, this accumulated time is 1500
At time, the microcomputer (27)
3) is excited to move the cylindrical cap (21) to the pull-out position, and at the same time, the LED for instructing filter replacement is turned on. Then, the smell of the air freshener is
The wind from (3) is emitted into the room, so the user knows that it is time to replace the dust collecting filter (9) with this odor.

The accumulated time is set assuming that the life of the dust collecting filter (9) is 1500 hours, but this is a value that should be appropriately changed depending on the type of filter and the place of use.

Further, the dust collection degree of the dust collection filter (9) is detected by integrating the driving time of the blower motor (12) by the microcomputer (27). Although configured, it does not depart from the gist of the present invention as long as it detects the dust collection degree of the filter. For example, if dust adheres to the dust collection filter, the filter will change color, so
The photodetector circuit (44) may be configured by the light receiving element, the light from the light emitting element may be reflected by the filter and received by the light receiving element, and the light reception amount may be used for the determination.

Further, although the air purifier has been described as an example, it goes without saying that any other air conditioner or the like may be used as long as it collects dust with a filter.

(G) Effect of the Invention The air conditioner of the present invention has the following effects.

(1) Since the dust collection filter replacement time is notified with an odor, the user is less likely to forget.

(2) Since it is aromatic and there is no sound, it does not make the user uncomfortable.

(3) With the fragrance, the odor emitted by the dust collecting filter can be erased.
