塵部(7)の集塵効率が向上するものである。The blower device (4) includes the fan case (5), a blower blade (22) positioned in the fan case (5), and an electric motor (23) for driving the blower blade (22). Although the blower blade (22) is a white fan in this embodiment, a tanzenshiaru fan or the like may be used. In this embodiment, an induction motor is used as the electric motor (23), and speed control taps (24), (25) and (26) for speed control are drawn for high speed, medium speed and low speed. The speed control tap (24) (25)
(26) is a switching element such as a triac (27) (28) (29)
Is connected to the commercial AC power source (21) via. The switching elements (27) (28) (29) are transistors connected via resistors (30) (31) (32) connected to their gate terminals.
The conduction is controlled by (33), (34) and (35). The transistor (33)
(34) and (35) are three-input AND circuits (3
6) The conduction is controlled by the outputs of (37) and (38). The AND circuit (3
6) Outputs from the comparators (39) (40) (41) are connected to inputs of (37) (38). The output of the comparator (39) is the AND circuit (3
Directly connect to 6) and NO to AND circuits (37) and (38).
Connect via T-circuit (42). The output of the comparator (40) is directly connected to the AND circuits (36) and (37),
The D circuit (38) is connected through the NOT circuit (43). The output of the comparator (41) is directly connected to the AND circuits (36) (37) (38). The output of the amplifier circuit (14) is connected to the positive inputs of the comparators (39) (40) (41). The comparator (39) (40)
The negative input of (41) is sequentially connected between the resistors (44), (45) and (46) connected in series with the DC circuit power supply (20). Therefore, the reference voltage V 3 of the negative input of the comparator (39), the reference voltage V 2 of the negative input of the comparator (40), and the reference voltage of the negative input of the comparator (41)
The V 1, the relationship of V 3> V 2> V 1 . The comparator (3
9), (40) and (41), which have the reference voltage smaller than the output voltage V of the amplifier circuit (14), output signals. When the output voltage V is higher than the reference voltage V 3 , the comparator (39)
And (40) and (41) all output signals, and the AND circuit (36)
Only the switching element (2
Only 7) conducts, and the electric motor (23) operates at high speed.
When the output voltage V is lower than the reference voltage V 3 and higher than V 2 , the comparators (40) and (41) output signals, and the AN
Since only the D circuit (37) outputs a signal, only the switching element (28) is conducted, and the electric motor (23) is operated at a medium speed. When the output voltage V is smaller than the reference voltage V 2 ,
Only the comparator (41) outputs a signal, and the AND circuit (3
Only the 8) outputs a signal, so that the switching element
Only (29) becomes conductive, and the electric motor (23) is operated at a low speed. When the detection unit (8) confirms that the degree of pollution is high, the electric motor (23) switches to an operating speed suitable for the degree of pollution even during medium-speed and low-speed operation. Since the air blower (4) is always in operation while the air purifier (1) is in operation, air always flows in the detector case (9) of the detector (8). Therefore, when the air is contaminated, the contaminated portion (for example, cigarette smoke) rides on the flow of the air and immediately enters the detection unit case (9), and can be detected by the detection unit. That is, it is quick to respond to changes in the degree of pollution in the room. The blower (4) is operated at high speed when the degree of pollution is high, and is operated at low speed when the degree of pollution is low. The dust collection efficiency of the dust collecting part (7) is improved by reducing the blowout of the collected dust particles during the measurement and improving the collection efficiency of the small particles.

However, a conventionally known motor control device can be used. Further, as shown in Japanese Patent Publication No. 52-25587, the dust collection efficiency can be further improved by controlling the applied voltage to the dust collecting part (7) at the same time as the control of the blower (4). .
