Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a so-called central cleaner in which a suction section of a vacuum cleaner body incorporating an electric blower is piped to each room.

Conventional configuration and its problems Figure 1 shows the general piping configuration of this type of central cleaner. This is a conduit connecting a hose insertion port 3 equipped at a position suitable for cleaning and a vacuum cleaner main body 1.

FIG. 2 shows the structure of the cleaner body 1, where 4 is an upper body with a built-in electric blower (not shown), and 5 is a collection unit which is detachably attached to the lower part of the upper body 4 via a buckle 6. A dust container, 7 is an intake hole provided in the dust collection container 5, 8 is a U-shaped support leg that is fixed to both sides of the upper body 4 and supports the cleaner body 1, and 9 is a handle for carrying the dust collection container 5. be.

Figure 3 shows the configuration of the hose insertion port 3.
Reference numeral 10 indicates a wall or floor surface to which the hose insertion port 3 is attached, and 11 indicates a connection body embedded in the wall or floor surface 10, and a pipe portion 12 is provided approximately in the center. Reference numeral 13 denotes a socket body having a socket 14 into which the end of a hose (not shown) is inserted, and is fixed to the outside of the wall or floor 10 together with the connector 11. 15 is a lid rotatably attached to the insertion port body 13, and 16 is a gasket fixed to the inside of the lid 15 to prevent air leakage from the insertion port 14. Reference numeral 17 indicates a gasket interposed at the joint between the outlet main body 13 and the connecting body 11, and 18 indicates the outlet 14.
This is a connection terminal provided in the hose section for electrical connection between the electric blower and a hand switch provided near the hose section. Reference numeral 19 denotes a finger hook portion for opening the lid 15, and the hose portion is inserted into the insertion port 14 after the lid 15 is opened, and is secured with a buckle or the like. However, with this configuration, anyone can use the finger hook 19 to hold the lid 15.
Since it can be opened, children, etc., can open the lid 15, put toys or large garbage, etc., and
Sometimes it got clogged.

OBJECTS OF THE INVENTION The present invention solves these conventional problems and provides a central cleaner that prevents children and the like from inserting foreign objects into the pipes.

Structure of the Invention In order to achieve the above object, the central cleaner of the present invention is provided with a permanent magnet on either the lid of the hose insertion port or the connecting end of the hose part, and the other is made of a magnetic material. .

This configuration prevents young children from opening the lid, prevents toys, trash, etc. from being tied to the hose insertion port, and allows the user to easily open the lid using magnetic force. It is possible.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. FIG. 4 is a sectional view of the connecting end of the hose portion of the central cleaner of the present invention. A hose connection tube 20 is fixed to one end of the hose 21. A ring-shaped permanent magnet 22 is integrally provided at the end of the hose connection tube 20. Further, a terminal 23 is provided in the vicinity thereof, and is electrically connected to a hand switch (not shown) via a reinforcing metal wire 24 of the hose 21.

FIG. 5 is a sectional view of the hose outlet of the central cleaner of the present invention.

Reference numeral 25 denotes a wall surface or floor surface to which a hose outlet is attached, and 26 a connection body buried in the wall surface or floor surface 25. A pipe portion 27 is provided approximately in the center. 28 is the insertion port 29 of the hose connection tube 20
The main body of the socket has a main body and is fixed to a wall or floor 25 together with a connecting body 26. Reference numeral 30 denotes a lid body made of a magnetic material and attached to the insertion port main body 28 while being biased in the closing direction by a spring; 31;
is a gasket fixed to the inside of the lid body 30 to prevent air leakage from the insertion port 28. Reference numeral 32 denotes a gasket interposed at the joint between the outlet main body 28 and the connecting body 26, and 33 a connection terminal provided in the outlet 29, which is connected to a circuit that controls the electric blower. The front surface 34 of the insertion port 29 is made of a magnetic material such as iron.

When a user cleans with the above configuration, the permanent magnet 22 at the end of the hose connection tube 20 is attracted to the lid 30 of the hose insertion port, and the lid 30 is opened.
Next, similarly, the permanent magnet 22 is attracted to the front surface 34 of the insertion port 29, and the terminals 23, 33 are brought into contact with each other.
Next, if you operate the hand switch of hose 21,
The electric blower operates and cleaning becomes possible.

When cleaning is completed, when the hose 21 is pulled, the hose connection tube 20 is separated from the insertion port 29, and the lid body 30 biased by the spring is closed. In other words, since there is no need for a handle or the like to open the lid 30, a child or the like cannot open the lid 30, and there is no need to tie the insertion port 29 with toys or the like.

Effects of the Invention As described above, the central cleaner of the present invention uses a permanent magnet when opening the lid, thereby eliminating the need for a finger hook, which prevents foreign objects from becoming clogged due to mischief by young children. It has great practical value.
