Definitions

  • the present invention relates to vacuum cleaners, more particularly, to a vacuum cleaner that broadcasts an artificial voice and a tune when it has finished cleaning.
  • Japanese Laid-Open Utility Patent Publication No. 1-41390 discloses a vacuum cleaner that picks up oil.
  • a thick, spongy filter that removes oil drops is attached at the upper side of a tank chamber.
  • a bag-like filter for removing dust is affixed in an air suction chamber at the upper side of the filter that removes oil drops. By beating the bottom of the bag-like filter, a dust-scattering device keeps the filter from becoming clogged.
  • a collision board is attached at the lower side of an air-guiding cylinder that has a suction inlet. The oil sucked from the suction inlet is removed by the spongy filter and drops to a tank chamber.
  • a worker feels satisfied and free on finishing a job. If the worker hears a voice and a tune, these feelings of satisfaction and freedom are increased. Hearing a voice and a tune also encourages the worker to start the next job.
  • An object of the present invention is to provide a vacuum cleaner that overcomes the lack of broadcast sound of the prior art.
  • a further object of the present invention is to provide a vacuum cleaner that offers a worker an encouraging voice and an uplifting tune when a job is completed.
  • a still further object of the present invention is to provide a vacuum cleaner that, by means of a voice and a tune, encourages a worker to feel satisfied and free and to start the next job.
  • the present invention provides, in a vacuum cleaner having a tank chamber, an air suction chamber, an air circulation chamber, and a motor chamber, a speaker mounted in the air circulation chamber.
  • a plurality of terminals in the motor chamber actuate: low-speed and high-speed modes of a main motor, a dust-scattering motor, a speech synthesis IC, and a music synthesis IC.
  • the terminals and a liquid level switch are connected to a microcomputer in the motor chamber.
  • a vacuum cleaner is characterized by apparatus to broadcast speech and music in response to a job-completion signal.
  • a vacuum cleaner is characterized by means for suctioning dust and liquid, means for holding the dust and liquid, means for actuating the means for suctioning, the means for actuating being responsive to the means for holding when the means for holding becomes full, means for communicating to an operator whether the means for holding is full, the means for suctioning having at least two modes, the means for communicating being disposed to communicate to the operator which of the at least two modes is operative, means for preventing an accumulation of the dust, the means for communicating disposed to communicate to the operator whether the means for preventing is operative, means for broadcasting speech and music to the operator, and the means for broadcasting being responsive to the means for actuating.
  • a vacuum cleaner is characterized by a tank chamber, an air suction chamber attached to the tank chamber, an air circulation chamber attached to the air suction chamber, a motor chamber attached to the air circulation chamber, the air suction chamber having a dust-scattering motor, the air circulation chamber having a speaker chamber with a speaker, a main switch, a remote control switch, a microcomputer, a main motor responsive to a one of the main switch and the remote control switch, the main motor disposed within the motor chamber to suction up dust and liquid, the main motor having at least two speeds, a liquid level switch disposed to stop the main motor when the tank chamber becomes full, a dust-scattering motor disposed within the air suction chamber to prevent an accumulation of the dust, a plurality of light-emitting-diodes (hereinafter "LEDs”) disposed to communicate to an operator which of the at least two speeds, the dust-scattering motor, and the liquid level switch is operative, a speech synthesis integrated circuit (hereinafter "LEDs”)
  • a vacuum cleaner has an air suction chamber attached to a tank chamber, an air circulation chamber attached to the air suction chamber, and a motor chamber attached to the air circulation chamber.
  • the air suction chamber has a dust-scattering motor.
  • a speaker chamber containing a speaker is placed in the air circulation chamber, which is divided by a wall.

  • the remote control switch is located next to a handle on a hose going into the air suction chamber.
  • a light-emitting-diode (hereinafter "LED”) controller selects between low-speed and high-speed modes and activates a dust-scattering motor, a numerical control, a speech synthesis integrated circuit (hereinafter “IC”), and a melody IC.
  • LED light-emitting-diode
  • the vacuum cleaner Turning on the power puts the vacuum cleaner into an initial mode. Turning on either the main switch or the remote control switch begins a power ON mode. The main motor's speed, low or high, is set by either the main switch or the remote control switch. Either the main switch or the remote control switch actuates a dust-scattering motor, placing the vacuum cleaner in a dust-scattering mode. A collar on a rod attached integrally to a motor driving shaft beats the bottom of a main filter so that stacked dust on the main filter is scattered.
  • a microcomputer is actuated.
  • a speech synthesis IC and a melody IC are in turn actuated by the microcomputer so that a voice telling the worker the job is done and a pleasant tune are broadcast from a speaker for about 36 seconds.
