Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention relates to a vacuum cleaner equipped with a suction hose that is rotatably connected to a vacuum cleaner body. The present invention relates to a connection structure between the hose side of wiring that extends into the vacuum cleaner main body along the hose, such as the wiring for use in the vacuum cleaner, and the vacuum cleaner main body side.

(Prior Art) Conventionally, in this type of vacuum cleaner, as shown in Japanese Utility Model Publication No. 48-5531, for example, the connection pipe portion of the hose on the vacuum cleaner body side is connected to the connection port of the vacuum cleaner body. The hose consists of a connecting pipe that is fitted and connected to the hose, and a bent suction pipe that is rotatably connected to the connecting pipe, so that the direction of the hose can be changed as the hose rotates. A similar structure has been adopted.

Also, Utility Model Application Publication No. 1986-94152, Utility Model Application No. 1987-
As shown in Japanese Utility Model Application Publication No. 97560, Japanese Utility Model Application Publication No. 60-97562, and Japanese Utility Model Application Publication No. 60-101051, the connecting pipe section of the hose is formed into a bent shape, and the connecting pipe section on the main body side is formed into a bent shape. There is also a structure in which the direction of the hose can be changed by making the connection port of the vacuum cleaner body to which the hose is connected rotatable.

In a vacuum cleaner with a freely rotatable hose, the wiring for remote control is connected to the hose side and the vacuum cleaner body side to operate the electric blower inside the vacuum cleaner body using the operating section provided on the hose. To electrically connect the
In the vacuum cleaner of Publication No. 5531, a fixed terminal part connected to the wiring inside the vacuum cleaner body is provided on the connection pipe of the hose, and an operating part provided on the outer peripheral surface of the suction pipe of the hose is electrically connected. A structure is adopted in which an annular sliding terminal portion is connected to the fixed terminal portion and slidably contacts the fixed terminal portion. Also, in 1987-
In vacuum cleaners such as those disclosed in Publication No. 94152, a ring-shaped sliding terminal part provided on the outer circumferential surface of the connection port of the vacuum cleaner body and a fixed terminal part fixed to the vacuum cleaner body are used for remote control. It has a structure in which the electrical connection between the hose side of the wiring and the cleaner body side is configured to be freely rotatable.

Further, an extension pipe and a suction port are connected in sequence to the hand-held portion of the hose, and for example, a structure is adopted in which the suction port is provided with an electric brush for scraping dust from the surface to be cleaned. In order to supply power to this electric brush, conventionally, as described in Japanese Patent Application Laid-open No. 56-68420, for example,
A structure is adopted in which one end is connected to the electric brush and a terminal provided on the other side of the power supply wiring is connected to a terminal provided on the vacuum cleaner body. In addition, the above-mentioned Japanese Patent Application Publication No. 56
In the vacuum cleaner described in Publication No. 68420, the terminals for the remote control wiring are also provided near the terminals for the power supply wiring, and two pairs of terminals are provided at the connection tube of the hose and the connection port of the vacuum cleaner body, respectively. It has a structure with

(Problems to be Solved by the Invention) Conventionally, a vacuum cleaner has a rotatable electrical connection between the hose side of the electric brush power supply wiring and the vacuum cleaner main body side, as well as the remote control wiring. However, in a vacuum cleaner that also has power wiring, in order to make the hose with built-in power wiring freely rotatable, the electrical connection part of the power wiring must also be fixed to the sliding terminal part as described above. It shall consist of a terminal section. Also, even if you run the power wiring from the hose to the outside of the vacuum cleaner with plenty of room, if the electrical connections between the two are not rotatable, the power wiring will get tangled with the rotating hose. A problem arises in which good operability is impaired during cleaning. However, when the electrical connections for both the remote control wiring and the power supply wiring are configured with a sliding terminal part and a fixed terminal part,
There is a risk of an increase in size and a risk of loss of insulation between the terminal parts, and the problem is how to solve these problems.

The present invention aims to solve these problems by making the hose rotatable relative to the vacuum cleaner body, and connecting not only the remote control wiring but also the power wiring for the electric brush of the suction port. In a vacuum cleaner in which the electrical connection part between the hose side and the vacuum cleaner body side is configured to be rotatable, the purpose is to make the electrical connection part as small as possible and to improve the insulation between the terminal parts. It is something.

In the vacuum cleaner, two pairs of wiring are provided along the hose that extend into the vacuum cleaner main body, including a remote control wiring and a power wiring for controlling the electric blower by an operation unit provided on the hose, and these wirings are provided. The two pairs of wiring electrically connect the hose side and the vacuum cleaner body side by means of an annular sliding terminal part that rotates with the hose and a fixed terminal part that is fixed to the vacuum cleaner body. The connection port body includes a flat plate portion perpendicular to the rotation axis direction thereof;
a cylindrical annular wall provided on the outer periphery of the flat plate portion and having the rotation axis as the central axis;
Furthermore, a sliding terminal portion of the remote control wiring is disposed on one of the flat plate portion and the annular wall of the connection port body, with the rotation axis as the central axis;

(Function) In the vacuum cleaner of the present invention, the connecting pipe portion of the hose is connected to the connecting port portion of the connecting port body rotatably supported by the vacuum cleaner body, so that the The suction port connected to this hose via an extension pipe or the like can be easily directed over a wide range. In addition to the remote control wiring for controlling the electric blower installed inside the vacuum cleaner body using the operating unit installed on the hose, there is also wiring installed on the suction port body to scrape out dust from the surface to be cleaned. The electrical connection between the hose side of the power supply wiring that supplies power to the electric brush and the vacuum cleaner body side is rotatable, so the hose can be rotated without any trouble, and the wiring can be connected to the hose easily. A decrease in cleaning efficiency due to entanglement is prevented. At this time, the sliding terminal part arranged on the flat plate part of the connection port body and the cylindrical annular wall with its rotation axis as the central axis slides on the fixed terminal part on the vacuum cleaner body side, but the remote control Since the sliding terminal portion of the power supply wiring and the sliding terminal portion of the power wiring are located on mutually perpendicular surfaces of the connection port body, insulation between the sliding terminal portions is maintained well.
