BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
[0015]
FIG. 1 shows a vacuum cleaner 1 according to the present invention. The vacuum cleaner 1 includes a cleaner body 2, a nozzle 3 (a suction tool) connected to a tip side of the cleaner body 2, and a power supply unit 4 provided on a base end side of the cleaner body 2. I have. Each member is arranged on a substantially straight line in the order of the nozzle 3, the cleaner body 2, and the power supply unit 4.
[0016]
As shown in FIG. 3, the cleaner main body 2 includes an electric blower chamber 6 inside a frame 5, and a dust collection chamber 7 that communicates with the electric blower chamber 6.
[0017]
The electric blower room 6 is provided with an enlarged portion 8 that expands from the base end side of the electric blower room 6 to the distal end side, and the outer diameter R1 of the electric blower room 6 is changed to the outer diameter R2 of the power supply unit 4. It is larger than. Inside the electric blower room 6, a small electric blower 9 is provided. An impeller 10 is rotatably mounted on a rotating shaft of the electric blower 9. The electric blower 9 is supplied with electric power from the power supply unit 4 via a connection terminal 11 and a wiring (not shown) provided in the cleaner main body 2 and is rotated. Further, since the enlarged portion 8 is provided in the electric blower room 6, the diameter of the impeller 10 can be made larger than that of the conventional vacuum cleaner 1, whereby the suction performance (cleaning performance) of the vacuum cleaner 1 can be improved. improves. Further, as shown in FIG. 2, an exhaust port 12 for discharging the exhaust from the electric blower 9 to the outside is formed in a portion of the frame 5 where the enlarged portion 8 is formed.
[0018]
The dust collecting chamber 7 has a substantially tapered shape tapering from a base end side to a distal end side, and is detachably attached to the electric blower chamber 6. In addition, a removable filter 13 is provided at an opening on the base end side of the dust collection chamber 7.
[0019]
The nozzle 3 includes a short nozzle 3a and a long nozzle 3b, and the short nozzle 3a is integrally attached to the dust collecting chamber 7. A check valve 14 is provided at an opening on the base end side of the short nozzle 3a, so that dust collected by the electric blower 9 does not return to the original position. As shown in FIG. 4, the long nozzle 3b is detachably attached to the short nozzle 3a. The outer diameter R3 of the nozzle 3 is designed to be smaller than the outer diameter R2 of the power supply unit 4.
[0020]
As shown in FIG. 4, the power supply unit 4 has a rechargeable battery 16 provided inside a substantially cylindrical grip 15. A switch 17 (shown in FIG. 1) is provided between the power supply unit 4 and the cleaner body 2. When the switch 17 is turned on, power is supplied from the secondary battery 16 of the power supply unit 4 to the electric blower 9. Is supplied. Thus, a cordless vacuum cleaner having improved usability can be provided. The outer diameter R2 of the grip 15 of the power supply unit 4 is designed to be a dimension (about 33 mm in the present embodiment) such that the user can grip with one hand. As shown in FIG. 4, the power supply unit 4 can be removed from the cleaner main body 2. When the power of the secondary battery 16 of the power supply unit 4 becomes low, the power supply unit 4 is removed from the cleaner main body 2. It can be charged by a separate charger (not shown). At the base end of the power supply unit 4, there is provided an indicator lamp 18 that lights up to indicate that charging is in progress. Further, a primary battery may be used instead of the secondary battery 16.
[0021]
The position of the center of gravity of the vacuum cleaner 1 is located at the base end side of the cleaner body 2, specifically, between the cleaner body 2 and the power supply unit 4, more specifically, at a position where the switch 17 is provided. are doing. Thereby, when the user uses the vacuum cleaner 1, the weight of the vacuum cleaner 1 is felt light and the operability of the switch 17 is improved. Further, since the position of the center of gravity of the vacuum cleaner 1 is located substantially on the central axis of the vacuum cleaner main body 2 (indicated by a dashed line in FIG. 3), the vacuum cleaner 1 is turned around the central axis of the vacuum cleaner main body 2. In this case, no moment is generated and the usability is good.
[0022]
Next, a case where the floor or a high place is cleaned using the vacuum cleaner 1 having the above configuration will be described.
[0023]
When the switch 17 of the vacuum cleaner 1 is turned on, the electric blower 9 is driven, and the impeller 10 is rotated. Then, dust on the floor surface or at a high place is guided from the nozzle 3 together with air via the check valve 14, and is stored in the dust collection chamber 7. The air sucked into the dust collection chamber 7 is guided into the electric blower chamber 6 through the filter 13 and is exhausted from the exhaust port 12 to the outside of the cleaner body 2. At this time, the air exhausted to the outside of the cleaner main body 2 is discharged in the radial direction of the cleaner main body 2 because the exhaust port 12 is formed in the enlarged portion 8 of the cleaner main body 2, and the air is discharged to the user's hand. I won't go. Thereby, the usability of the vacuum cleaner 1 is improved.
[0024]
In addition, when cleaning floors, high places, and gaps between furniture, the long nozzle 3b is used for cleaning, and when cleaning a desk or the like, the long nozzle 3b is removed from the cleaner body 2 to remove the short nozzle. You may clean in 3a. When the interior of the dust collection chamber 7 is full of dust or dirt, the cleaner main body 2 is divided into the electric blower chamber 6 and the dust collection chamber 7, and the filter 13 of the dust collection chamber 7 is removed. The dust or trash in 7 can be discarded.
[0025]
Next, a case where the vacuum cleaner 1 is stored will be described.
[0026]
As shown in FIG. 5, the vacuum cleaner 1 is stored in a standing state by inserting the tip of the long nozzle 3b into the insertion port 21 of the separate storage table 20. The storage table 20 has a substantially disk shape with a convex center. Alternatively, as shown in FIG. 6, the short nozzle 3a may be stored by inserting the tip of the short nozzle 3a into the insertion port 21 of the storage table 20.
[0027]
The storage table 20 is provided with a detachable attachment 22 with a wide or brush, and as shown in FIG. 7, the attachment 22 can be efficiently cleaned by attaching the attachment 22 to the tip of the nozzle 3 according to the object to be cleaned. It has become.
[0028]
As a modified example of the above-described embodiment, as shown in FIG. 8, the power supply unit 4 is not arranged substantially in a straight line with respect to the cleaner body 2, but is arranged at a predetermined angle to improve usability. May be improved.
[0029]
【The invention's effect】
As is clear from the above description, according to the present invention, the cleaner body is provided with an enlarged portion having an outer diameter larger than the outer diameter of the power supply unit, and the exhaust from the electric blower is externally provided in the enlarged portion. Since the exhaust port for exhausting air to the vacuum cleaner is formed, the air exhausted to the outside of the cleaner main body does not reach the user's hand, thereby providing a vacuum cleaner with improved usability. In addition, since the enlarged portion is provided in the cleaner main body, an electric blower having a larger size than that of the conventional vacuum cleaner can be provided, and the effect of improving the cleaning performance is also achieved.
