Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a so-called central cleaner in which a hose outlet serving as a suction part of a 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, where 1 is the main body of the cleaner installed at any location in the house, and 2 is used for cleaning rooms. This is a conduit that connects a hose insertion port 3 provided at a suitable position 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 main body having a socket 14 into which the end of a hose (not shown) is inserted, and is fixed together with the connecting body 11 to the outside of the wall or floor 10 . 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 for opening the lid 15, and the hose connection tube is inserted into the insertion port 14 after opening the lid 15, and is secured with a buckle or the like.

With the above configuration, the user opens the lid 15 of the hose insertion port 3 provided in each room, inserts the hose part therein, and turns on the switch provided on the hose part. When the switch is turned on, the electric blower inside the vacuum cleaner main body 1, which is electrically connected via the connection terminal 18, is turned on. The suction air of the electric blower is drawn from the hose through the pipe 2, allowing the user to clean.

However, with this configuration, after cleaning one area, the user must return to the hose outlet 3, operate the buckle, etc., and pull out the hose from the hose outlet 3 before moving to the next cleaning area. Instead, it became extremely troublesome.

Purpose of the invention The present invention solves these conventional problems,
To provide a central cleaner that obtains a strong bonding force during cleaning and can be detached by simply pulling the hose on the hand side without having to return to the hose insertion port each time when detaching.

Structure of the Invention In order to achieve the above object, the central cleaner of the present invention includes a cleaner body, a plurality of hose outlets arranged inside a house, a conduit connecting the cleaner body and the hose outlets, and a pipe line connecting the cleaner body and the hose outlets. A lid body that opens and closes the insertion port, and a hose portion that is detachably inserted into the hose insertion port and has a hand switch that remotely controls the cleaner main body, One side is energized by the hand switch. The structure includes an electromagnet that is turned off, a permanent magnet, and a magnetic material on the other side. With this configuration, a very strong bonding force between the hose outlet and the hose part can be obtained by the electromagnet during cleaning, and the hose part can be detached by simply pulling the hose part lightly.

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 connection side of the hose portion of a central cleaner according to an embodiment of the present invention.
A hose connection tube 20 is fixed to one end of the connection side of the hose portion 21. A magnetic ring 22 made of iron or the like 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 a hose insertion port of a central cleaner according to an embodiment 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 hose connection tube 2 shown in Fig. 4.
The main body of the socket has a socket 29 of zero, and is fixed to the outside of a wall or floor 25 together with a connecting body 26. Reference numeral 30 denotes a lid attached to the insertion port main body 28 while being biased in the closing direction by a spring or the like (not shown); 31 is a gasket fixed to the inside of the lid 30; Prevents air leaks. 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 the terminal 23 shown in FIG. 4. Furthermore, a ring-shaped permanent magnet 34 and an electromagnet 35 are arranged on the front surface of the insertion port 29.

FIG. 6 is a circuit diagram, in which 36 is a magnetic relay, 37 is an electric blower, and 38 is a hand switch located on the hand side of the hose portion 21. The magnetic relay 36 has a primary coil 39 connected to a power source, a secondary coil 41 connected to the hand switch 38 via remote control wiring 40, and contacts 42 and 43 that close when the hand switch 38 is closed.
It consists of. Contact 42 controls electric blower 37, and contact 43 controls electromagnet 35.
The voltage generated by the secondary coil 41 is low enough to be safe even if touched by a person.

The operation of the above configuration will be explained below.

When cleaning, first, the lid 30 of the insertion port 29 is opened and the hose connection tube 20 is brought into contact with it, and the magnetic ring 22 is attracted to the permanent magnet 34, completing the connection. Terminals 23 and 33 are also joined. next,
When the hand switch 38 of the hose section 21 is closed, the contacts 42 and 43 of the magnetic relay 36 are closed.
The electric blower 37 is energized to enable cleaning, and at the same time, the electromagnet 35 is also energized and the magnetic ring 22 is attracted more strongly. When the user finishes cleaning using one outlet, the user presses the hand switch 3.
When 8 is opened, the electric blower 37 is stopped and the electromagnet 35 is also de-energized, and the connecting force between the hose connection tube 20 and the insertion port 29 is only due to the permanent magnet 34, and the hose 21 By pulling on the proximal side, the hose connection tube 20 is removed from the insertion port 29, and the lid body 30 is closed. Therefore, the user does not have to go to the outlet 29 when removing the hose 21 from the outlet.

Effects of the Invention As is clear from the above description of the embodiments, the central cleaner of the present invention uses both a permanent magnet and an electromagnet to connect the hose part and the hose outlet, so that the hose part is not pulled during cleaning. Obtains a strong bonding force that prevents the hose from coming off from the outlet due to
When cleaning is finished and the hose outlet is moved, the hose part can be removed from the outlet simply by pulling the hose part. Therefore, there is no need to return to the hose insertion port each time the hose insertion port is moved, and cleaning can be performed efficiently.
