い込み力で清掃ができるものである。Next, the operation of this embodiment will be explained. In the above configuration, when the power is turned on, the oscillation means 12 provided in the hand operation section 6 sends an oscillated signal to the sound field detection means 13. Based on this signal, the sound field detection means 13 consisting of an ultrasonic element or the like emits a sound wave and detects a sound field. The signal output from the sound field detection means 13 will be explained using FIG. 3. When cleaning is not being performed, the human body and the hand-held operation unit 6 are stationary, and the sound field is stable as shown in (a). Furthermore, when cleaning is performed, the distance between the human body and the hand-held operating section 6 changes due to movement of the human body. In this case, the sound field fluctuates as shown in (b), and an alternating current component with a period synchronized with the reciprocating motion of the hand-held operation unit 6 is generated. In this embodiment, the cleaning state is detected by utilizing the difference in waveform due to the change in the sound field due to the movement of the human body. In other words, when the hand-held operation unit 6 is moving, the sound field detection means 13, which includes an ultrasonic element or the like, converts the above-described fluctuating sound field into an electrical signal. The amplifying means 14 amplifies this signal and sends the signal to the state detecting means 8. The state detection means 8 detects the cleaning state and sends a signal to the motor control means 11. Based on this signal, the motor control means 11 controls the suction motor 10 to increase its rotational speed, and this control generates a strong suction force, allowing the user to clean with a strong suction force.

ができる。Furthermore, while cleaning work is not being performed, the hand-held operating section 6 is in a stopped state. While the handheld operating section 6 is in this state, the output signal of the sound field detection means 13 has no AC component in its signal waveform, as shown in FIG. 3(a). From this, there is no alternating current component in the signal sent to the amplification means 14, and the state detection means 8 sends this signal to the motor control means 11 of the main body 9 indicating that cleaning is not actually in progress. Based on this signal, the motor control means 11 controls the suction motor 10 to lower the rotational speed of the suction motor 10. This control reduces the suction force and prevents unnecessary power consumption.

This second embodiment has the structure of the first embodiment shown above, but is provided with speed detection means 15 for detecting the cleaning speed based on the signal from the sound field detection means 7. This speed detecting means 15 includes an F-V converting means 16 for F-V converting the signal from the sound field detecting means 7, and this F-V converting means 16.
The speed determination means 17 includes a comparator or the like that determines the cleaning speed based on a signal from the cleaning device. The other configurations are the same as those of the first embodiment shown above, so explanations will be omitted. Note that the sound field detection means 7 may be any device that can detect changes in the sound field caused by the human body, and may be provided in the main body 9, for example. Further, the speed detection means 15 may be of any type as long as it can detect the cleaning speed, and is not limited to the configuration of this embodiment. Furthermore, speed detection means 1

In the above configuration, the signal from the sound field detection means 7 is an alternating current component with a period synchronized with the reciprocating motion of the hand operation unit 6, and the F-V converting means 16 converts the frequency of the alternating current into a voltage. and sends a signal to the speed determining means 17. That is, when fast cleaning is occurring, the voltage is high, and during slow cleaning, the voltage is low. Based on this signal, a speed determining means 17 consisting of a comparator or the like determines the cleaning speed and sends a signal to the motor controlling means 11. Based on this signal, the motor control means 11 controls the suction motor 10 to increase the rotational speed of the suction motor 10 in the case of a fast cleaning state. Further, in the case of a slow cleaning state, the suction motor 10 is controlled to lower the rotation speed of the suction motor 10. This control reduces the suction force and prevents unnecessary power consumption.

制御し、不用な電力の消費を防ぐことができる。Next, the operation of this embodiment will be explained. In the above configuration, the light emitting means 19 made of an infrared light emitting element or the like emits light, and the emitted light is received by the light receiving means 20 made of a light receiving element or the like. If there is no dust, the light receiving means 20 receives a certain amount of light and sends this signal to the dust determining means 21. Further, if there is dust, if the dust enters between the light emitting means 19 and the light receiving means 20 opposite to the light emitting means 19, the light emitted from the light emitting means 19 will be blocked by the dust and the amount of light received will be reduced. This signal is sent to the dust determination means 21. The dust determining means 21 detects dust by identifying the difference in the amount of light emitted from the light emitting means 19 that is blocked by dust. In other words,
Dust detection means 18 detects dust sucked in from the suction nozzle. Even when there is little movement of the hand-held operation part 6, such as when cleaning a corner, if there is dust that is sucked in, the dust detection means 18 detects the dust and sends a signal to the state detection means 8. Based on this signal, the state detection means 8 determines the cleaning state and sends a signal to the motor control means 11. Based on this signal, the motor control means 11 controls the suction motor 10 to increase its rotational speed, and this control allows cleaning with a strong suction force. After that, the dust disappears and the dust detection means 1
8 detects that the dust is gone and sends a signal to the state detection means 8. Based on this signal, the state detection means 8 determines the cleaning state and sends a signal to the motor control means 11. Using this signal, the rotation speed of the suction motor 10 can be controlled to be lowered, thereby preventing unnecessary power consumption.

In other words, even if the suction nozzle is stopped, if there is dust, the suction force can be increased, and when there is no more dust, the suction force can be lowered. The vacuum cleaner can automatically determine the cleaning state and the dust state and control the suction motor, and can provide a highly efficient vacuum cleaner with an energy-saving configuration without sacrificing cleaning performance.
