Abstract

PURPOSE:To eliminate a possibility that a carpet, etc., are damaged due to an edge brush and to improve a usability by covering and bending the root added part of the edge brush with a cylinder body when a cleaner main body is in a standing condition. CONSTITUTION:The title cleaner is composed of a suction port body 7 to rotably mount a rotary brush 8 to brush up a dust and, simultaneously, to equip an edge with an edge brush 16, a blast room 3 to be turnably mounted to the suction port body 7 and to be equipped with a motor fan 2 both for sucking a dust and for driving a rotary brush inside, and a cleaner 1 main body in which a dust collecting room 4 to collect the dust is formed. In the vicinity of the edge brush 16 arranging part of the rotary brush 8, a cylinder body 17 to be slidably fitted in a lengthwise direction outside the rotary brush 8 and to interlock with the turn of the cleaner 1 main body to the suction port body 7 is provided, and the root added part of the edge brush is covered and bent with the cylinder body 17 when the main body 1 is in the standing condition. As a result, the possibility that the carpet, etc., are damaged by the edge brush can be eliminated.

Description

[Detailed description of the invention] Industrial applications The present invention relates to an upright vacuum cleaner.

BACKGROUND OF THE INVENTION In order to increase the effective cleaning width of conventional upright vacuum cleaners, edge brushes are also implanted at both ends of a rotating brush provided inside the suction body.

Problems to be Solved by the Invention In general, upright vacuum cleaners are constructed with a single power source serving as both a power source for sucking in dust and a power source for rotating a rotating brush, and the power source is used as a power source for sucking in dust and for rotating a rotating brush. The suction hose that sends out dust has a suction body. At this time, since the brush bristles are provided in a spiral between both ends of the rotating brush, for example, even when rotating on a carpet, the part of the bristles in contact with the carpet changes as it rotates. Although it does not easily damage the carpet.

Special R: Since the edge brushes at the ends of the rotating brushes are provided on the same circumference, they rotate while always contacting the same portion of the carpet, resulting in the problem of damaging the carpet.

In addition, there was a problem in that the power cord easily entered between the edge brush and the floor surface, and the covering portion of the power cord was heated and melted due to the rotation of the edge brush, causing damage.

The present invention solves this problem by completely separating the edge brush from the floor surface when the vacuum cleaner is placed in a standing position, thereby preventing damage to the floor surface caused by rotation of the edge brush. The purpose is to prevent damage to the cord.

Means for Solving the Problem In order to solve this problem, the present invention provides a suction body rotatably equipped with a rotary brush having an edge brush at the end for scraping dust, and a suction body. a vacuum cleaner body which is rotatably mounted and has a blower chamber provided with an electric blower for driving a front rotating brush for dust suction and a dust collection chamber for collecting dust; A cylindrical body is provided in the vicinity of the edge brush arrangement portion, and is slidably fitted in the longitudinal direction on the outside of the rotating brush to interlock the rotation of the vacuum cleaner body with respect to the suction body, and when the vacuum cleaner body is in a standing state, The cylindrical body is configured to cover and bend the base of the edge brush.

With this configuration, when the rotary brush is rotating, even if the vacuum cleaner body is kept stationary in a standing position 9, the edge brush always maintains a distance from the floor surface because the base part is bent by the cylindrical body. The edge brush eliminates the possibility of damaging carpets and power cords, improving usability.

EXAMPLE Hereinafter, an example of the present invention will be described based on the drawings.

First, in FIG. 1, reference numeral 1 denotes a vacuum cleaner body, which includes a ventilation chamber 3 having an electric blower 2 for sucking dust inside, and a dust collection bag 4 that collects the dust sucked in at the upper part of the ventilation chamber 3. It is equipped with a dust collection chamber 5 that stores the dust. The ventilation chamber 3 and the dust collection chamber 5 are in communication with each other through a filter 6 that captures fine dust that has passed through the dust collection bag 4. Reference numeral 7 denotes a suction body mounted on the lower end of the vacuum cleaner body 1 so that the vacuum cleaner body 1 can be tilted freely, and a rotary brush 8 that can freely rotate is provided inside the tip. This rotating brush 8 is attached to a belt 9
It is rotated by the driving force of the electric blower 2 via the electric blower 2 . The suction chamber lO at the tip of the suction body containing the rotating brush 8 is the vibrator 1.
It communicates with the hose attachment part 12 via 1. Reference numeral 13 denotes a hose, one end of which communicates with the dust collection bag 4, and the other end of which is detachably connected to the end of the vibrator 11 in the hose attachment portion 12. Reference numeral 14 indicates a switch for controlling energization of the electric blower 2, and reference numeral 15 indicates an operation handle extending upward from the vacuum cleaner main body l.

Next, in FIGS. 2 to 5, 16 is a rotating brush 8.
17 is a cylindrical body that is slidable in the longitudinal direction of the rotary brush 8 and is fitted on the outside of the rotary brush 8 and rotates together with the rotary brush 8. This is the edge brush 1 at both ends of the rotating brush 8.
It is located near the inside of 6. Reference numeral 18 denotes a rod, which is urged toward the lower front end of the cleaner body 1 by a spring (not shown). Further, as shown in FIG.
It slides back and forth against a concave portion 19 and a convex portion 20 formed at the bottom of the. Reference numeral 21 denotes a frame, which is attached to the suction body 7 so as to be slidable along the longitudinal direction of the rotating brush 8. Further, this frame 21 is loosely fitted onto the rotating brush 8#, and the cylindrical body 1
A roller 22 in contact with the roller 7 is provided.

A sliding shaft 23 is rotatably attached to the rod 18 and the frame 21 via shafts 24 and 25.

In the above configuration f, switch 1 is pressed during normal floor cleaning.
4, hold the operating handle 15, and tilt the cleaner body 1 as shown by the two-dot chain lines in FIGS. 3 and 4 to clean. At this time, the end of the rod 18 is connected to the recess 1 of the cleaner body 1.
9 and moves in the direction of arrow A shown in FIGS. 2 and 3. In conjunction with the movement of this rod 18, the frame 21 moves toward the center in the longitudinal direction of the rotating brush 8 via the sliding shaft 23, as shown in FIG. 5(a), and the edge brush 16 is in a free state. When cleaning the floor, it rotates together with the rotary brush 8 to scrape up dust on the floor. Next time you clean anything other than the floor,
Remove the hose 13 from the hose attachment part 12, and
For cleaning, either by directly suctioning from the end of the hose 13 or by attaching an attached attachment (not shown) to the end of the hose 13, place the vacuum cleaner body 1 in a standing position as shown by the solid line in Figure 4. and quiet it down.

At this time, as shown by the solid line in FIG. 3, the end of the rod 18 comes into contact with the zero section 20 of the cleaner body 1, as shown by the solid line in FIG.

It operates in the direction of arrow B shown in FIG. This movement of the rod 18 is linked to the frame 21, which moves to both ends in the longitudinal direction of the rotating brush 8 via the sliding shaft 23, as shown in FIG. The base is covered and bent to ensure it is away from the floor.

Effects of the Invention As described above, according to the present invention, when the rotary brush is rotating, even if the main body of the vacuum cleaner is kept stationary in a standing state, the edge brush is always bent by the cylindrical body so that it does not fall on the floor. Keep your distance.

The edge brush eliminates the possibility of damaging carpets and power cords, improving usability.
