Description

CENTRAL DUST COLLECTION VACUUM CLEANER}

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 having a suction head for a bed that can easily and easily clean the bottom surface of a bed that is difficult to clean using the suction head of a general vacuum cleaner.

In general, a central dust collector is a system for installing a main body of a vacuum cleaner in a room which is not affected by noise, and installing a suction pipe in various directions inside the wall to clean the room through an inlet installed in the room.

Therefore, it is not necessary to move the main body of the heavy vacuum cleaner, and since the vacuum cleaner main body is provided in the room which is not affected by the noise, it is quiet, and fine dust can be prevented from being discharged back to the air discharge port.

Referring to Figure 1 showing the state of use of a conventional centralized vacuum cleaner as follows.

As shown in FIG. 1, the central dust vacuum cleaner is connected to the cleaning main body part 110 and the cleaning main body part 110 disposed in a space which is not affected by noise, and divides each divided compartment space. The suction pipe part 120 disposed to pass through, the extension pipe connection part 130 formed so that the end of the suction pipe part 120 protrudes on one side wall of the partition space, and can be attached and detached to the extension pipe connection part 130. Extension tube 140 and the suction head 150 is coupled to the extension tube 140 to perform the cleaning.

The cleaning main body 110 is composed of a suction fan for generating a suction force therein, a filter member for filtering foreign substances sucked with air, and a dust collecting unit for collecting the filtered foreign substances, and the air containing the foreign substances on the side of the dust collecting unit. The suction port for suctioning the outlet, and the discharge port for discharging only the sucked air is formed in the upper portion of the suction fan.

The suction pipe part 120 is connected to the suction of the cleaning main body part 110 and is connected to the suction main pipe installed in the wall or floor surface via the partitioned space, and the suction main pipe is in communication with one side of each compartment space It consists of a suction branch pipe extending to the wall.

The extension pipe connecting portion 130 is formed at each end of the suction branch pipe, it is configured to be used in combination with the extension pipe 140.

The extension pipe 140 is coupled to the extension pipe connecting portion 130 is configured with a flexible bending hose having a predetermined length so that one end is connected to the distal end of the suction branch pipe and the other end is coupled to the suction head.

One end of the suction head 150 is connected to the extension tube, the other end is connected to the suction plate 151 formed with a suction hole on the bottom to suck the air containing the foreign matter, the handle is formed with a control button It consists of a bar 152.

When the user wants to clean the space by this configuration, the extension pipe 140 and the suction head 150 to move to the corresponding space by inserting the extension pipe connecting portion 130 formed in the space to be cleaned In the combined state by operating the operation button formed on the handle bar 152 of the suction head 150, the cleaning main body portion 110 including the suction fan is driven.

When the suction fan starts driving, foreign matter is introduced into the suction head 150 together with air from the outside, and is introduced into the dust collector through the extension pipe 140 and the suction pipe part 120, and the air introduced into the dust collector. Is discharged to the outside of the cleaning main body portion 110 and the dust and foreign matter is collected by the filter member inside the dust collector.

Even if the cleaning is performed by replacing the shape of the suction head coupled to the conventional centralized vacuum cleaner, it is not easy to clean the bottom surface of the bed that still forms a gap having a low depth and an extension pipe. And hassle to move with suction head.

In order to solve the above problems, the present invention forms a bed suction head having a suction port on the bottom of the suction pipe having a low height and a long length to conveniently clean the bottom surface of the bed, and the bed suction head for the bottom of the bed It is an object of the present invention to provide a centralized vacuum cleaner including a suction head for cleaning the bed resident on the surface.
