    摘要: At an interior portion of a suction nozzle body, an impeller and a brush member are installed. The impeller is rotated in response to an air flow produced by a suction force and a brush or a blade member is mounted in a spiral shape along the whole impeller or a part of the impeller and contacts a surface to be subjected to cleaning. The rotary brush rotates integrally with the impeller on the same shaft and no partition wall is provided between the impeller and the rotary brush. A suction nozzle body having a small size, and which is of light weight and provides for silent operation, and a vacuum cleaner using the same, can be provided.

    摘要: A vacuum cleaner having a vacuum cleaner main body, an electric blower motor provided in the vacuum cleaner main body, a dust collection part provided in the vacuum cleaner main body, a suction nozzle body for communicating with the dust collection part, an impeller having a rotary axis provided in an interior portion of the suction nozzle body and driven by a suction force which is generated by said electric blower motor. At least one of a rotation brush member and a rotation blade member is included in the suction nozzle body and an opening portion of the suction nozzle body is opposed to a surface to be subjected to cleaning, a suction inlet port for the suction nozzle body is provided for sucking air from an outside portion and is located separately from the opening portion of the suction nozzle body. The suction inlet port is provided so as to direct air which is sucked from the outside portion in a direction transverse to the rotary axis of the impeller and an air flow passage is formed in the suction nozzle body so that a part of the air which is sucked from the suction inlet port initially impinges on the impeller to rotate the impeller and then is passed to a region of the surface to be subjected to cleaning and is sucked into the vacuum cleaner main body.

    摘要: A control circuit comprises a first counter for counting up stepping pulses and counting down the number of steps of a stepping motor, a memory for storing therein a drive timing of the stepping motor, a variable timer for converting a data in the memory to a real time, a second counter for counting up an output signal of the variable timer when a count of the second counter is smaller than a count of the first counter and counting down the output signal of the variable timer when the count of the second counter is equal to or larger than the count of the first counter, and a drive circuit for driving the stepping motor in accordance with the output signal of the variable timer.Signals to set the first counter in the count-up mode and the count-down mode are synchronized with two clock signals having the same frequency and different phases. The control circuit drives the stepping motor immediately after the control pulse signal was applied to accelerate or decelerate the stepping motor so that a velocity pattern of the stepping motor is controlled in a pedestal pattern.

    摘要: A self-running vacuum cleaner comprises a homing mode of following a back of a user with receiving a signal from a light emitting means or a transmitting means of a position indicator means held by the user, an instruction operation mode, in which the user instructs a cleaning area to the self-running vacuum cleaner, and an execution mode for cleaning up the cleaning area instructed. When the self-running vacuum cleaner operates under the homing mode or the instruction mode, a signal from the light-emitting means or the transmitting means is received by a receiver means attached on a periphery portion of a measuring means, which is provided in an upper portion of the vacuum cleaner. Comparing the signals from the two (2) receiver means in strength thereof determines the distance and the direction from the position indicated by the light-emitting means or the transmitting means up to the vacuum cleaner.
