Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a vacuum cleaner in which a hose connecting pipe connected to a hose is rotatably connected to a main body of the vacuum cleaner.

2. Description of the Related Art In a conventional vacuum cleaner of this type, a hose connection portion is provided on the top surface of the top lid 2 of the vacuum cleaner body 1, which is formed approximately parallel to the floor surface, as shown in FIG. Hose 3 was connected. The hose connection portion was formed so that the connected hose 3 could freely rotate around a normal line 4 at the connection portion to the upper lid 2.

Problems to be Solved by the Invention However, as shown in FIG.
As shown in the figure, when used upright in the middle of stairs, the hose 3 bends at the end 6 of the hose connection pipe 6, and if this is repeated frequently, this part may tear or break. A problem arose.

Moreover, since the hose connection pipe 6 is bent at a substantially right angle, ventilation resistance is added to the airflow passing through the inside, which causes a reduction in dust suction performance. Furthermore, there was a phenomenon in which the inhaled dust got stuck in the bent parts.

Means for Solving the Problems The technical means of the present invention for solving the above-mentioned problems is to set the hose connection part of the vacuum cleaner main body, which is rotatably held by the hose, about 30-66cm above the floor surface. It is tilted at a degree.

Effect This effect is as follows. In other words, by arranging the hose connection part at an angle of approximately 30 to 60 degrees with respect to the floor surface, the bending angle of the hose connection pipe is made smaller than before, thereby preventing dust clogging at the bend part. The electric blower is designed to prevent this, reduce ventilation resistance, and fully utilize the suction power of the electric blower.

Furthermore, when the hose is pulled upward, the hose is not bent at the end of the hose connection pipe, thereby preventing the hose from being broken or cut.

Example An embodiment of the present invention will be described below with reference to the accompanying drawings.

In FIGS. 1 and 2, 11 is the main body of the vacuum cleaner with a built-in electric blower 12, and the interior is divided into two parts, front and back, and the rear side includes the electric blower 12 and a cord winding device (not shown).
A dust collection chamber 1 houses a filter unit 14 on the front side for collecting and depositing dust sucked in through a hose 13, an extension pipe, and a floor suction device (not shown).
5 is formed. A pair of rear wheels 16 are attached to both sides of the rear end of the main body 11, and a front wheel 17 is attached to the bottom fixture of the dust collection chamber 16, which facilitates movement of the vacuum cleaner during use.

18 is a rotating plate arranged between the upper lid 19 and the upper lid stopper plate 20;
Reference numeral 21 designates a rotary plate contact plate fixed to the rotary plate 18, and 22 also represents a rotary plate support plate. The hose connection pipe 23 is connected to the rotating plate 18
is inserted and connected.

The rotating plate support plate 22 rotatably slides on the surface of the upper lid abutment plate 20 on the upper lid 19 side. As a result, the hose connection pipe 23 freely rotates relative to the upper cover 19, that is, the main body 11 of the vacuum cleaner.

Further, the rotary plate 18 and the rotary plate support plate 22 are arranged on the inner surface of an inclined surface 24 of the upper lid 19 which is inclined at an angle of approximately 30 to 60 degrees with respect to the floor surface.

Reference numeral 26 denotes a paper bag frame glued to a paper bag 27 which is arranged in the dust collection chamber 16 so as to come into contact with the rubber valve 26 attached to the top cover plate 20, and which accumulates the inhaled dust inside. , the filter unit 14 is composed of a paper bag 27 and a paper bag frame 26, and a zero buckle 30 supported by a lip 28 and a bag support frame 29 in the dust collection chamber 16 is attached to the upper lid 1e and is attached to the main body 11. The paper bag 27 is replaced by releasing the upper cover 19 and lifting it upward.

Furthermore, when the hose connection pipe 23 is inserted and connected to the rotary plate 18 and directed toward the front of the main body 11, the protrusion angle of the hose 13 protruding from the other end of the hose connection pipe 23 is formed to be slightly above the horizontal direction. I'm here.

Next, the operation of this configuration will be explained.

The hose connection pipe 23 is attached to the upper lid 19 on the inclined surface 24 of the upper lid 19, and since the rotary plate 18 is rotatable around the normal line 31, the hose 13 is attached to the rear of the main body 11. When pulled, it points almost vertically upward, as shown by the dashed line in Figure 2. Therefore, when cleaning a high place such as a ceiling or a shelf, the hose 13 will not be bent at the protruding portion of the hose connection pipe 23, and will not be damaged.

This also applies when the device is used standing up on stairs or the like.

Furthermore, since the inclined surface 24 has an inclination angle of 30 to 60 degrees with respect to the floor surface, the bending angle θ of the hose connection pipe 22 is
is θ: (120~1so)+a (α≧0), and the effect of the invention on the suction performance of the electric blower 12 due to the ventilation resistance caused by the change in the air inflow direction at the bending part. By making the connection pipe rotatable relative to the vacuum cleaner body and by slanting this hose connection part approximately 30 to 60 degrees with respect to the floor surface, the hose can be prevented from being torn or cut due to bending, and the hose connection pipe can be easily rotated. Lowering at bends and clogging with dust? This provides a highly usable vacuum cleaner.
