JPS5851882Y2 - Vacuum cleaning device hose plug - Google Patents

Description

[Detailed description of the invention] The invention consists of a vacuum cleaner body, a pipe line that is piped inside the house and transmits the dust suction power of the main body, a plurality of hose plugs provided at the ends of the pipe line, and This invention relates to a so-called concentrated dust collection type vacuum cleaning device that has a hose inserted into a hose insert, an extension pipe connected to the hose, and a floor nozzle, and is characterized by the shape of the insert.

In the centralized dust collection method, the main unit does not move, a long hose is connected to the plug, and the area within the reach of the hose is cleaned.

Therefore, in order to improve the operability of the hose and to make it possible to clean the entire room, a plurality of plugs are usually installed.

However, when installing it, it is necessary to consider the arrangement of furniture and furnishings, opening and closing of doors, wiring, etc., and the location is limited.

As with power outlets, if you attach a plug to the wall, the conditions will be eased, and the hose will be easier to insert and the appearance will be better.

However, in the past, the depth of the plug was determined by taking into account the length required to connect the hose and the space required to prevent debris from clogging, so the dimensions were naturally fixed, and the thickness was greater than that dimension. Installation locations were limited to places with a structure that allowed escape to the back, such as walls, closets, etc.

The present invention enables the depth dimension to be further reduced while ensuring the necessary dimensions, and the one-channel flow side thereof will be explained below with reference to the accompanying drawings.

In the figure, 1 is the main body of the vacuum cleaner, 2 is a pipe piped inside the house, 3 is a hose plug, an extension pipe connected to the hose, and the dust that has passed through the floor nozzle is inserted into the above plug. It moves through the tube 2 via the tool 3 and is housed in the main body 1.

FIG. 3 shows the structure of the plug 3, where 4 is a wall, 5 is a hose connection pipe, 6 is an insertion part of this hose connection pipe 5, 7 is a bent part, 8 is an introduction part to the pipe 2, and 9 10 is a connection pipe connecting the pipe 2 and the connection part 9, and 11 is a fixing screw.

The introduction tube portion 8 is inclined by an amount a with respect to the center line of the tube 2.

As a result, the pipe 2 can be installed near the center of the wall space, and the insert 3 can have a dimension A at the depth limit O of the wall space.

In this case, as shown in FIG. 4, the connecting portion 9 is parallel to the tube 2, but the inner diameter of the introducing tube portion 8 is an elliptical shape with the center shifted by a distance C due to the inclination a.

By bending the airflow by more than 90 degrees, it is possible to prevent dust from clogging the pipes in this area.

As described above, according to the present invention, in addition to the normal insertion depth dimension,
The introduction part is bent into a straight pipe, and the outer diameter of the connecting pipe that fits into the connecting part is added as an increment, requiring a wide internal wall dimension, and the pipe is often placed on one side of the wall, making the work difficult. However, since the introduction part is tilted toward the hose plug attachment wall and the connection part is not tilted, the inner dimensions of the wall can be reduced, piping can be facilitated, and the mounting range can be widened.
