Description

[Detailed description of the invention]

[Industrial Application Field] The present invention relates to an electric vacuum cleaner, and more particularly to an electric vacuum cleaner equipped with an electric floor suction power outlet. [Prior art] A vacuum cleaner equipped with an electric floor suction power outlet is
For example, it is described in Japanese Unexamined Patent Publication No. 53-49128, and is provided on the top surface of the vacuum cleaner body, and the lid is opened when not in use. In this way, the main body of the vacuum cleaner was equipped with a power outlet, and a cord could be connected to the electric floor suction port as needed. [Problems to be Solved by the Invention] In order to improve the handling and operability of a vacuum cleaner, the main body of the vacuum cleaner and the hose joint connected to the main body are configured to be rotatable. If you wire the power cord along with the extension tube and hose and connect it to the power outlet of the vacuum cleaner, the rotation of the vacuum cleaner and hose will be controlled by the power cord of the electric floor suction device connected to the vacuum cleaner. This caused problems in handling and operability. Additionally, since excessive force such as pulling and bending is applied to the power cord when the vacuum cleaner body and the hose rotate, improvements were needed from the standpoint of reliability and safety. In addition, since the power outlet is installed in the vacuum cleaner body, some specifications are changed for the same body and the product is made into a series, so if you do not trust the power outlet, it will affect the overall product design and may be undesirable in terms of design. This was one of the reasons why the structure became complicated due to the large number of constraint conditions. An object of the present invention is to improve the drawbacks of the prior art described above and to provide a vacuum cleaner with excellent handling and operability. In addition, it is possible to easily develop a series of products, and the simple structure reduces product cost increases. [Means for Solving the Problems] In order to achieve the above object, the power outlet 1- of the electric floor suction tool is provided in the hose joint connected to the cleaner body. Furthermore, this is achieved by holding the power outlet with a hose joint cover that is divided into left and right halves. [Function] By providing the power outlet of the electric floor suction device at the hose joint that connects to the vacuum cleaner body, the power cord of the electric floor suction device will obstruct the turning ability of the vacuum cleaner body and the hose joint. The vacuum cleaner has excellent handling and operability. Also, since the vacuum cleaner itself does not have a power outlet,
There is a degree of freedom in design, and it is also easy to create a product series with a power outlet or hand-made one. Furthermore, by configuring the hose joint cover into left and right halves to hold the power outlet, the structure is simple, has a small number of parts, is easy to assemble, and can further reduce the product cost of the vacuum cleaner. Furthermore, by providing the power outlet on the lower side of the hose joint, dust is less likely to enter, and therefore a highly reliable vacuum cleaner with no electrical contact failure can be achieved.

A cylindrical sound-absorbing cover 49 made of a sound-absorbing material is provided on the outer periphery of the motor portion of the electric blower 7. [Effects of the Invention] As described above, according to the present invention, the following effects can be expected. (1) By providing the power outlet of the electric floor suction device at the hose joint that connects to the vacuum cleaner body, the power cord of the electric floor suction device will impede the turning ability of the vacuum cleaner body and the hose joint. There is no. A vacuum cleaner with excellent handling and operability can be obtained. (2) Since there is no power outlet on the vacuum cleaner body, there is a degree of freedom in design, and it is easy to create a product series with a power outlet or a manual one. (3) By configuring the hose joint cover into left and right halves to hold the power outlet, the structure is simple, the number of parts is small, and it is easy to assemble in one piece, which in turn makes it possible to suppress an increase in the product cost of the vacuum cleaner. (4) By providing the power outlet at the lower side of the hose joint, dust is less likely to enter, and therefore a highly reliable vacuum cleaner with no electrical contact failure can be achieved.
