BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a centralized vacuum cleaner, and more particularly, to a centralized vacuum cleaner in which a heavy cleaner main body having a motor and a cord retractor therein is fixed in one place so that a user can conveniently use the vacuum cleaner.

1, the length of the power cord 9 is approximately 5 to 7 m, the length of the hose 20 is approximately 1.3 to 2.0 m, and the other components, that is, The apparatus is incorporated in the cleaner main body 1.

However, since such a cleaner as described above requires heavy cleaning to keep the main body 1 from moving in order to move the cleaning place when the user uses it, the user's body becomes slippery, In addition, the power cord was scattered in the sea, which made it difficult to move the body, which made it more fatiguing.

Also, since the power cord of the cleaner and the length of the hose are limited when moving in a wide place, it is not inconvenient to use the power cord by pulling out the power cord and plugging it into an outlet installed in another place.

Accordingly, a centralized cleaning system is used as shown in FIG. 2 or FIG. 3 in order to solve the above problems.

That is, the centralized cleaning system refers to a system in which the main body 1 is installed in one of the rooms, and a piping P is constructed inside the ceiling or wall surface, and a fitting hose 22, (30) is installed to carry the hose, the extension pipe, and the suction port while cleaning, and is inserted into the fitting part (30) installed in each of the rooms to clean the corresponding room.

However, the biggest problem of the above-mentioned cleaning system is that, in the construction of the new house, the construction cost and the housing design cost are borne only by the piping work. However, in case of the existing house,

Another problem is that when cleaning foreign matter in the piping, it is necessary to remove the floor, ceiling or wall, remove the foreign material, remove the foreign matter, reassemble the piping and repair the floor, ceiling or wall. There was a problem.

SUMMARY OF THE INVENTION Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and an object of the present invention is to provide a hose which can be extended and shortened in length from the main body and the hose, And the floor is cleaned by turning on the switch installed on the main body, there is no inconvenience of dragging the main body and fatigue caused by the main body, and since the main body is not located near people but is located at a certain place, Especially, since the main body is installed in the case, the use of the main body is more quietly, so that the mental fatigue of the user can be solved.

In order to accomplish the object of the present invention, there is provided an electric motor comprising: an electric motor generating a suction force; A dust collecting device for collecting dust and the like; A cleaner main body having a power supply device for connecting a power source and having a handle, an extension pipe, and an inlet; The centralized vacuum cleaner is installed at a predetermined place in a house. The centralized vacuum cleaner includes an outer case for housing the main body and storing accessories such as a hose; A plurality of hoses connected to the main body and interconnectable therewith; And a connection device is provided at both ends of the hose to connect the hose and the hose.

The connecting device includes a male connector having a power pin formed at one end of the hose, and a female connector having a pin hole for inserting the power pin into one end of another hose, and a power source for connecting the power source to the power pin, And the power pin and the power supply are connected to a power line embedded in the hose.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

As shown in Fig. 4, the present invention comprises: a motor 6 generating a suction force; A dust collecting device 5 for collecting dust and the like; A cleaner main body (1) having a power supply device for connecting a power source and having a handle (4) and an extension pipe (3) and a suction port (2); A centralized vacuum cleaner provided with a main body (1) at a certain place in a house, comprising: an outer case (10) in which the main body (1) is embedded and in which accessories such as the hose (20) are stored; A plurality of hoses (20) connected to the main body (1) and capable of being interconnected; A connecting device 100 is provided at both ends of the hose 20 to connect the hose 20 and the hose 21 to each other.

5, the connecting device 100 includes a power connector 111 having a power pin 111 formed at one end of the hose 20 and a power pin 111 And a female connector 120 provided with a power supply piece 122 for contacting a power supply pin 111 in the pin hole 121 to connect the power supply.

The power supply pin 111 and the power supply pin 122 are connected to a power supply line 130 installed in the hose 20 or 21.

The operation and effect of the centralized vacuum cleaner constructed as described above will be described in detail as follows.

A hose 20 and 21 which can be extended and shortened in length from the main body 1 and a hose 20 and 21 which are provided in the outer case 10 can be provided in the outer case 10, After the hoses 20 and 21 are taken out, the floor 8 is turned on by turning on the switch 8 provided on the main body 1 shown in FIG.

The expansion and shortening of the hoses 20 and 21 are performed by connecting the power pins 111 of the male connector 110 connected to the power line 130 in the hose 20 to the other hose 20, (120) having a pin hole (121) into which the power pin (111) is inserted.

Therefore, the vacuum cleaner assembled as described above has the following advantages.

First, there is no inconvenience and body fatigue.

Secondly, since the main body is not located near a person but is located in a certain place, it is difficult to feel the noise generated from the main body. Especially, since the main body is installed in the case, it is used more quietly so that the mental fatigue of the user can be solved.

Third, since the power cord is not spread on the floor, there is no need to interfere with cleaning and to hang over the cord.

Fourth, there is no inconvenience that the ceiling, the floor, and the wall are opened and constructed in order to construct a centralized system as in the past.
