Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a vacuum cleaner equipped with a rotating brush for removing dust attached to a surface to be cleaned.

2. Description of the Related Art Conventional Structures and Problems There have been conventionally known vacuum cleaners equipped with a rotating brush that separates dust attached to a surface to be cleaned from the surface to be cleaned.

The configuration will be explained based on FIGS. 1 and 2. In the figure, 1/fi, the vacuum cleaner body, the electric blower
is placed horizontally and tucked inside. 3 is a floor nozzle, and a rotating brush 4 is installed inside the nozzle, allowing you to select an electric blower. The rotational force of 2 is transmitted by the belt 6.

The dust separated from the surface to be cleaned by the rotating brush 4 is
Due to the suction force of the electric blower 2, the dust is sucked from the intake passage 6 through the hose 7 into the dust collection chamber 9 in front of the filter 8 provided 1 iF above and on the side of the electric blower 2.

However, in the above configuration, since the electric blower 2 is placed horizontally on the floor nozzle a side of the cleaner body 1, the width of the cleaner body 1 increases, and the fan side of the electric blower 2 increases. Diameter of vacuum cleaner body 10 floor nozzle 3
It has the disadvantage that it has a fixed thickness and is thick overall, so it cannot fit into low spaces such as under beds or desks, and cannot be cleaned.

In addition, there is also a vacuum cleaner in which the electric blower 2 is placed vertically inside the upper part of the vacuum cleaner body 1, and the thickness of the floor nozzle 3 side of the vacuum cleaner body 10 is made thinner so that it can clean low gaps such as under the bed. However, in this case, in order to drive the rotating brush 4 in the floor nozzle 3, a rotating brush driving electric motor is required separately from the electric blower 2, which increases the weight and cost. Furthermore, since the electric blower is located at the top of the vacuum cleaner, it feels heavy when you hold it in your hand, making it difficult to operate.

Purpose of the Invention In view of the above-mentioned drawbacks, the present invention makes it possible to make the vacuum cleaner body slim and to reduce the thickness of the floor nozzle side of the vacuum cleaner body, thereby making it possible to clean gaps in low places such as under beds and desks. To provide a vacuum cleaner with good operability, which does not add weight to the hand when holding the vacuum cleaner.

Structure of the Invention To achieve this object, the vacuum cleaner of the present invention has an electric blower vertically installed inside the floor nozzle side of the vacuum cleaner body with the fan side facing upward and the motor side facing downward. The rotational force of the electric blower is transmitted to the rotating brush of the floor nozzle.

With this configuration, the vacuum cleaner body is slim and the thickness of the floor nozzle side is thinner, making it possible to clean crevices such as under beds and desks.In addition, the electric blower is located at the bottom of the vacuum cleaner body. When cleaning, there is almost no increase in the perceived weight when held in the hand, the rotating brush can be rotated by an electric blower, no electric motor for the rotating brush is required, and there is no increase in cost or weight.

DESCRIPTION OF THE EMBODIMENTS In the following description of the embodiments of the present invention, reference will be made to the drawings.The floor nozzle is rotatably attached to the removal machine body 10, and 12 is a handle.

On the floor nozzle side of the vacuum cleaner body 1o, there is a 77-inch 13a machine 13.
is installed vertically, and the first one is parallel to the electric blower shaft 14.
A shaft 15 is supported by a first bearing 16 . A first belt 18 is stretched between the electric blower shaft 14 and a first shaft pulley 17 attached to the first shaft 16.

A power transmission shaft 19 such as a flexible wire is attached to one end of the first shaft 15.
is connected to the second shaft 22 through the center of rotation of the cleaner body 1o and the floor nozzle 11. The second shaft 22 is provided in parallel with the rotary brush 21 that is rotatably supported inside the floor nozzle 11 by a rotary brush bearing 2o. Further, this second shaft 22 is supported by a second bearing 23 . A second belt 26 is stretched between the second shaft pulley 24 attached to the second shaft 22 and the rotating brush pulley 25.

Inside the floor nozzle 11, a suction passage 28 is formed from a suction port 27 opened on the lower surface, and the suction passage 28 is connected to a dust collection chamber 3o in front of a filter 29 formed inside the cleaner body 1o. Pipe button 1 is connected.

As described above, the electric blower 13 is vertically installed inside the vacuum cleaner body 1°, so the width of the vacuum cleaner body 10 is equal to the width of the electric blower 1.
It is only slightly larger than the diameter of 3, making it a reduced type. In addition, since the electric blower 13 is installed with the large diameter fan side facing upward and the small diameter motor side downward, the vacuum cleaner main body 10
It is possible to form a thin part 32 by making the vacuum cleaner main body 1o smoothly increase in thickness from the end side on the floor nozzle 11 side to the position of the electric blower 13, so that it can fit deep into gaps etc. It has become. Note that if the fan side 13a of the electric blower 13 is located downward, the diameter of the motor side is also larger, so the end portion of the cleaner main body 1o becomes thicker.

The operation of the vacuum cleaner configured as described above will be explained below.

The output of the electric blower 13 is transmitted from the first shaft 15 to the power transmission shaft 19 via the electric blower shaft 14, the first belt 18, and the first shaft pulley 17.

Here, the rotational speed of the electric blower 13 is reduced. The power transmitted to the power transmission shaft 19 is transferred from the second shaft 22 to the second
The rotating brush 21 is rotationally driven via the shaft pulley 24, the second belt 26, and the rotating brush pulley 26.

The dust separated from the surface to be cleaned by the rotating brush 21 is sucked from the suction port 27 through the suction passage 28 and the connecting pipe 31, and accumulates in the dust collection chamber in front of the filter 29.

As described above, according to this embodiment, the electric blower 13 is installed vertically inside the vacuum cleaner body 10 on the floor nozzle 11 side with the fan side facing upward and the motor side facing downward. The rotational force is transmitted to the motor by means of a power transmission shaft 19. For this reason, the vacuum cleaner body 10 is thinner,
Moreover, since the thickness of the vacuum cleaner main body 10 can be made into a thin part 32 that is smoothly thickened from the floor nozzle 11 side, it is possible to deep clean even in crevices such as under a bed or a desk. Further, since a separate electric motor is not required to drive the rotating brush 21, the cost and weight do not increase. Furthermore, since the electric blower 13 is located on the floor nozzle side of the cleaner body 10, the handle 12 feels lighter when held in the hand.

Effects of the Invention As described above, the vacuum cleaner of the present invention has an electric blower vertically installed inside the vacuum cleaner body on the floor nozzle side with the fan side facing upward and the motor side facing downward. By transmitting rotational force using a power transmission shaft, the vacuum cleaner body can be made thinner and the thickness of the vacuum cleaner body 6 can be smoothly increased from the floor nozzle side, making it easy to use under beds and desks. It is possible to clean deep into low spaces such as Furthermore, the electric blower is located on the floor nozzle side of the vacuum cleaner, so
The weight of the vacuum cleaner feels light when you hold it in your hand. Furthermore, since the rotating brush can be driven by the electric blower, there is no need for a separate electric motor or the like for driving the rotating brush, so there is no increase in weight.
