Description

Cleaner {CLEANER}

The present invention relates to a vacuum cleaner comprising cleaning aids such as a rotary brush driven by an electric motor at a floor suction port connected to an air intake port of a vacuum cleaner body via an intake hose and an extension pipe.

The vacuum cleaner widely used in homes includes a cleaning main body including an electric fan for intake, a dust collecting chamber for dust collection, an inlet and an exhaust port, and a wheel for moving the floor, and flexible to the suction port. An extension pipe connected through an intake hose having a thinness, and a suction port freely detachable at the tip of the extension pipe, hold the operation knob provided at the base of the extension pipe, It is used while driving the electric fan in this state by pressing the suction port attached to the tip while moving the cleaning main body from the floor.

At this time, the flow of the intake air introduced into the cleaning main body from the intake port through the extension pipe, the intake hose and the intake port by the rotation of the electric fan, and the dust around the intake port together with the intake air is sucked into the dust collecting chamber installed in the electric fan. Is collected.

In the vacuum cleaner configured as described above, the suction port provided at the tip of the extension tube efficiently performs dust collection by the intake air, and has various effects such as the shape of the suction port and the shape of the brush surrounding the suction port. Another type of thing is prepared, and it is possible to obtain good dust collection performance by using it according to the cleaning surface to be used suitably.

The floor suction port used for the inside and the bottom surface of this type of suction port is a rectangular opening with a wide opening centered on the communication port with the extension pipe for the purpose of cleaning the floor surface widely applied with high efficiency. Although it is comprised by the suction port of this, there exists a problem that dust collection power is lacking because the said intake port is large dimension.

In addition, Japanese Unexamined Patent Application Publication No. 6-8852 (A47L 9/28, 5/28), etc. includes a battery inside the cleaning main body and drives an electric fan for intake by supplying power from the battery. Although rechargeable vacuum cleaners have been proposed to improve the operability by eliminating the need for a power cord for connection to an external power source, it is difficult to improve the intake performance of an electric fan in such a vacuum cleaner, and it is difficult to increase dust collection power when using a floor inlet. Lack is more pronounced.

In order to solve such a problem, conventionally, a cleaning auxiliary means for assisting dust collection and a floor suction hole having an electric motor for driving the dust collecting device are widely used. The cleaning auxiliary means is provided with, for example, a brush on the circumferential surface of the cylindrical body hypothesized to cross the suction inlet and is configured as a rotary brush which is driven to rotate in the axial rotation by the electric motor and the suction inlet is pressed The periphery of the place is shaken off to remove dust from the place and aid in their aspiration.

Thus, in the case of using the floor suction port having the cleaning auxiliary means as described above, power supply to the electric motor that is the driving source of the cleaning auxiliary means is required, and this power supply is delivered in accordance with the extension pipe and the intake hose. The configuration is such that the conductive wire is connected to the power supply in the cleaning main body.

However, in this configuration, a connection mechanism of the conductive wire is required at the connection portion between the cleaning main body and the intake hose, and at the connection portion between the intake hose and the extension tube, and the configuration of the intake hose and extension tube including the connection mechanism is complicated. In addition, the extension pipe is generally configured by connecting a plurality in the longitudinal direction, and can be used to change the length by connecting or disconnecting according to the cleaning location, in this case, the connection mechanism is also required in the connection portion of the extension pipe Will lead to complexity.

In addition, the connection mechanism is inevitable that the contact failure between the use of the intake hose and the extension pipe is removed over the long term as a result of repeating the connection and disconnection every time the removable intake hose and extension tube is removed, in this case, the cleaning auxiliary means provided in the floor suction opening does not operate There was a fear that good cleaning performance could not be obtained.

On the other hand, in the vacuum cleaner disclosed in Japanese Unexamined Patent Application Publication No. 6-8852, the battery inside the cleaning main body is charged through the terminals in contact with each other when the cleaning main body is placed on the charging target during non-use. Foreign matter adhered to the terminal exposed to the outside during the cleaning operation performed by removing the charge from the charging stand, which may cause unreasonability such as poor conductivity or short circuit.

In view of the above circumstances, the present invention can operate the cleaning auxiliary means such as the rotary brush provided at the floor suction port, without supplying power from the cleaner body, thereby eliminating the need for conductive wires along the intake hose and the extension pipe. In addition to simplifying the construction, it is possible to provide a vacuum cleaner which can prevent the occurrence of malfunction caused by contact failure occurring in the connection portion of the conductive wire and to perform a sure auxiliary operation for a long time. It is also an object of the present invention to provide a vacuum cleaner that can be reliably charged without contact due to the attachment of foreign matter.
