御が困難であるという課題があった。In such a conventional vacuum cleaner, the motor current is detected, and the power supplied to the motor is controlled based on the detected current value. However, since the motor has an L load, a phase difference occurs between the voltage and the current.

減する。FIG. 4 is a characteristic diagram of air flow versus electric power due to variations in the motor 2. When dust is excessively accumulated in the dust bag or when a suction port (not shown) is clogged, the air volume Q flowing to the motor 2 decreases, and the motor 2 is overheated. Therefore, conventionally, when the air volume falls below the air volume Q1 on the temperature limit curve shown by the broken line as shown in FIG. 4, the power supplied to the motor 2 is reduced from P1 to P2,
Abnormal heating of the motor 2 was prevented. First, motor 2
The current I flowing to the motor is detected by the current detecting means 3, the current value is input to the air flow detecting means 11, and the air flow detecting means 11 determines the air flow as Q1, and controls the electric power supplied to the motor 2 based on the detection result. Was. However, when the motor 2 varies, the air flow differs even with the same current. The difference in the air volume means that the degree of overheating of the motor 2 is also different, and it is necessary to correct the degree of overheating for reducing the supply power according to the supply voltage and the power factor. For example, when the power factor is small or the voltage is high, the temperature limit air volume increases from Q1 to Q2, and when the power factor is large or the voltage is low, the temperature limit air volume decreases from Q1 to Q3. Therefore, in the present invention, the determination result of the air volume determination unit 11, the voltage value, and the power factor are input to the air volume correction unit 12, and the present condition is corrected with respect to a predetermined condition for determining the air volume Q1. For example, when the power factor varies to a higher value or a lower voltage, the air volume increases for the same current value. In addition, even at the same air volume, the current (power) is small, and the temperature of the motor 2 is not so high. Therefore, it is possible to make the air flow point for reducing the supplied electric power smaller than Q1 (Q3). Conversely, if the power factor varies to a smaller value or a higher voltage, the air volume decreases for the same current value. Also, when the current (power) increases even at the same air volume, the motor 2
Temperature will rise too much. Therefore, the airflow point at which the supplied power is reduced is made larger than Q1 (Q
2) It is necessary. The second control means 13 sets the amount of electric power to be supplied to the motor 2 according to such a correction result. If the air volume is equal to or less than the correction air volume, the power supplied to the motor 2 is reduced.

る。FIG. 6 is a characteristic diagram of the amount of dust versus the power due to the variation of the motor 2. The operation of the above configuration will be described. Conventionally, when dust accumulates in the dust bag, the air volume Q flowing to the motor 2 decreases, and the current (electric power) flowing to the motor 2 also changes. The change in the current (electric power) is used to determine the amount of waste in the garbage bag, and notify the user of the amount of waste accumulated. First, the current detection means 3 detects a current I flowing through the motor 2 and determines the value of the current I as a garbage amount determination means 21.
And the refuse amount determination means 21 determines the amount of refuse, and displays or informs the refuse amount based on the result of the determination.
However, when the motor 2 varies, the air flow differs even with the same current. The difference in the amount of air means that the amount of accumulated dust is also different, and it is necessary to correct the amount of waste according to the supply voltage and the power factor. Therefore, in the present invention, the determination result, the voltage value, and the power factor of the dust amount determination unit 21 are input to the dust amount correction unit 22, and the current condition with respect to the condition (motor, voltage) in which the preset air volume Q4 is determined Is corrected. For example, when the power factor varies to a higher value or a lower voltage, the air flow increases for the same current value. In addition, even at the same air volume, the current (power) becomes smaller,
The amount of waste is reduced. Therefore, it is necessary to make the air volume point for outputting the amount of dust smaller than Q4 (Q5). Conversely, if the power factor varies to a smaller value or a higher voltage, the air volume decreases for the same current value. Further, even at the same air flow rate, the current (electric power) is increased, and the amount of dust is too large. Therefore, it is necessary to make the air volume point for outputting the amount of dust larger than Q4 (Q6). The output means 23 outputs the amount of dust in accordance with such a correction result.
