The switching control unit 10 is configured to perform switching control between an operation mode mainly having a dust collection function and an operation mode mainly having a deodorizing function. The circuit configuration of the switching control section 10 will be explained with reference to FIG. In the figure, 101 is a switch for operation operation, 103 is a neon lamp that indicates the on state of the switch 101, 4 is a motor (capacitor motor) for fan 2, and 102 is used to control the rotation of motor 4 for high speed and low speed. This is a switch for switching the operation mode to two stages.

In this example, the blood collection characteristics and fruit removal characteristics with respect to the fan air volume have the following relationship.

That is, as shown in FIG. 11, the blood collection characteristics are more efficient than when the air volume is small because the dust concentration decreases at a large rate as the air waiting time elapses.

On the other hand, as shown in FIG. 12, when the air volume is large, the rate at which the odor concentration decreases over time is smaller than when the air volume is small, so the deodorizing efficiency is poor.

From the above, when the air volume is large, the deodorizing efficiency decreases while the dust collection efficiency increases, and when the air volume is small, the dust collection efficiency decreases while the deodorization efficiency increases, which are contradictory characteristics.

The switching control section 10 controls the switch 10 when the power is turned on.
1 is turned on, the neon lamp 103 lights up to indicate that the mode 4 is being driven, and the motor 4 is driven to rotate at high or low speed according to the switching position NC or NO of the switch 102 for switching the operation mode. I have to. Therefore, when the motor 4 is driven at high speed by switching the switch 102, the air volume of the fan 2 is large and the filtering means 3
Further, when the motor 4 is driven at a low speed, the air volume of the fan 2 is small, and the operation mode is set such that the deodorizing function by the filtering means 3 is the main one.

In addition, in FIG. 9, an integrating unit of a timer TM is connected to one side COM of the switch 102, and when the motor 4 reaches the set time of the timer TM, a lamp 104 consisting of a light emitting diode is turned on to replace the filtering means 3. The time is displayed, and the backup power supply section of the timer TM is connected to the power supply 110 so that, in the event of a power outage, the timer TM retains the accumulated value up to that point.

The switches 101 and 102 and the lamp 103
, 104 are installed on the front part of the first panel 11 as shown in FIG. 10 in consideration of operability and display performance.

In addition, as shown in the figure, the operating state of the operation mode switching switch 102 is displayed in an easy-to-understand manner to indicate which of the deodorizing and dust collection operations is performed more frequently in each mode.

In the air cleaner with a deodorizing function of the embodiment, when the switch 101 of the switching control circuit section 10 is turned on when the power is turned on, the fan 2 is driven, so that the outside air is drawn from the suction port 12 of the second pile 11 of the casing 1. The air sucked into the fan 2 and discharged from the fan 2 is filtered through the filtering means 3.
The dust is collected and purified by deodorization, and then blown out from the air outlet 14 of the second panel 13.

At this time, the switching control circuit section 10 controls the contents of the operating mode according to the switching operation of the operating mode switching switch 102. That is, when the switch 102 is switched to the attitude-based mode, the high rotation of the motor causes the fan 2 to
Since the air volume becomes large, the dust collection function of the overpassing means functions more efficiently than the deodorizing function, and the dust collection function is effectively utilized. On the other hand, when the switch 102 is switched to the deodorizing mode, the air volume of the fan 2 is reduced due to the low rotation of the motor, so the deodorizing effect of the filtration means 3 functions more efficiently due to the dust collection effect, and the deodorizing function becomes effective. Utilized.

Therefore, the switching control circuit unit 10 can change the air volume of the fan to switch between an operation mode mainly based on the dust collection function and an operation mode mainly based on the deodorization function, so that the dust collection function and the deodorization function can be effectively utilized. .

In the present invention, the configuration of the switching control circuit section 1O is not limited to the illustrated embodiment, and it is sufficient if it has the desired function.
