  Moreover, the front-end | tip part of the small nozzle 10 incorporates the 1st illumination means 14 for irradiating a to-be-cleaned surface, and the 1st illumination part for irradiating the to-be-cleaned surface to the right-and-left tip part of the floor nozzle 11 is built-in. Two illumination means 15 are incorporated. In the present embodiment, the first illuminating means 14 and the second illuminating means 15 are composed of LEDs or the like.

  Next, the control method of the vacuum cleaner in this Embodiment is demonstrated using FIG.

  The vacuum cleaner main body 1 includes a driving means 17 composed of a bidirectional thyristor for driving the electric blower 2 so that the suction force can be changed by controlling the phase of the electric blower 2. Yes.

  The control means 16 composed of a microcomputer or the like takes in the switch operation information of the hand operation section 5 and performs control to output a call pulse for phase control to the drive means 17 based on the information.

The attachment / detachment detection means 18 provided in the small nozzle 10 detects attachment / detachment between the small nozzle 10 and the floor nozzle 11, and cleans the attachment / detachment state signal of the small nozzle 10 via the extension pipe 4 and the hose 6. It is sent to the control means 16 in the machine body 1. In response to the attachment / detachment signal, the control means 16 supplies power to the first illumination means 14 provided in the small nozzle 10 via the hose 6 and the extension pipe 4. Also, the control means 16 is supplied with electric power to the second illumination means 15 provided in the floor nozzle 11 via the hose 6, the extension pipe 4, and the small nozzle 10 according to the attachment / detachment signal. It has become.

  Further, a signal of the amount of dust detected by the dust detection unit 7 is sent to the control unit 16, and the control unit 16 supplies power to the first illumination unit 14 and the second illumination unit 15 according to the amount of dust. Change the supply amount.

  About the vacuum cleaner in this Embodiment comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  For example, when the user operates the hand operation unit 5 and selects the “strong” mode having a strong suction force as the operation mode of the electric blower 2, the control means 16 is based on the signal from the hand operation unit 5, A predetermined signal is sent to the driving means 17 to drive the electric blower 2. Thereby, it is sucked from the suction tool 3 by the suction air generated by the electric blower 2. The sucked dust is collected in the dust collection chamber 19 in the cleaner body 1 through the extension pipe 4 and the hose 6.

  Next, the operation of the first illumination means 14 and the second illumination means 15 will be described using the timing chart of FIG.

  First, in a state where the vacuum cleaner is not operated, that is, in a state where the electric blower 2 is not driven, power is not supplied to the first illumination unit 14 and the second illumination unit 15 and is in an OFF state. . Then, at time Ta0, the electric blower 2 is driven by the user. At that time, for example, when the attachment / detachment detection means 18 detects that the small nozzle 10 is attached to the floor nozzle 11, the second illumination means. The power is supplied to 15 to be turned on, and the surface to be cleaned is irradiated. At this time, power is not supplied to the first illumination means 14. While the attachment / detachment detection means 18 detects that the small nozzle 10 is attached to the floor nozzle 11, the second illumination means 15 is kept in the ON state, and the first illumination means 14 is also in the OFF state. continue.

  Next, when the attachment / detachment detection means 18 detects that the small nozzle 10 has been removed from the floor nozzle 11 by the user (Ta1), power is supplied to the first illumination means 14 to turn on, and the surface to be cleaned is irradiated. To do. Since power is supplied to the second illumination means 15 via the small nozzle 10, the power is not supplied when the small nozzle 10 is removed from the floor nozzle 11. The illumination unit 15 is turned off. And while the attachment / detachment detection means 18 detects that the small nozzle 10 is in a state of being removed from the floor nozzle 11, the ON state of the first illumination means 14 continues.

  When the small nozzle 10 is mounted on the floor nozzle 11 again, the second illumination means 15 is turned on, and the first illumination means 14 is turned off (Ta2).

When the user stops the operation of the electric blower 2, the power supply to the second lighting unit 15 is also stopped, and both the first lighting unit 14 and the second lighting unit 15 are turned off.
Further, in the present embodiment, as shown in FIG. 5, the amount of power supplied to the first illumination means 14 and the second illumination means 15 is changed according to the amount of dust detected by the dust detection means 7, The illuminance changes.

For example, when no dust is detected, the illuminance of the first illuminating means 14 and the second illuminating means 15 is the initial illuminance C1. maintain. And when the detected dust amount is Q1 or more and less than Q2, the illuminance is C2. In this way, the illuminance of the first illuminating means 14 and the second illuminating means 15 changes stepwise according to the detected amount of dust, and the user sucks with a vacuum cleaner. When the amount of dust is large, the surface to be cleaned is irradiated more brightly, and when the amount of dust sucked is small, the illuminance of irradiation on the surface to be cleaned is suppressed.

  Since the vacuum cleaner in the present embodiment is configured and controlled as described above, when cleaning a wide place, the surface to be cleaned is irradiated by the second illumination means 15 provided on the floor nozzle 11 to thereby create a staircase. When cleaning a narrow and dark place such as between furniture and furniture, the surface to be cleaned is irradiated by the first illumination means 14 provided on the small nozzle 10 to improve the visibility of dust over a wide range. In addition, dust can be prevented from being left behind, and when the small nozzle 10 is mounted on the floor nozzle 11, the power supply to the first illumination means 14 provided in the small nozzle 10 that is not used is stopped. In addition, when the small nozzle 10 is removed from the floor nozzle 11, the power supply to the second illumination means 15 provided in the floor nozzle 11 that is not used is stopped, and the vacuum cleaner is sucking. To vary the amount of power supplied to the first lighting unit 14 and the second illumination means 15 in response to the amount of dust, it is possible to provide an excellent vacuum cleaner to user-friendly energy saving.

  As described above, the vacuum cleaner according to the present invention is easy to use and can improve the visibility of dust in a dark and narrow place, and is applicable to various vacuum cleaners for home use, business use, and store use. it can.
