Description

SUCTION APPARATUS OF CENTRAL DUST COLLECTION TYPE VACUUM CLEANER FOR ENTRANCE HALL}

The present invention relates to a suction device for a porch of a centralized vacuum cleaner, and more particularly, a centralized vacuum for facilitating the cleaning of a front door and to remove and remove foreign substances in clothes and / or shoes when entering and exiting. It relates to a suction device for the porch of the vacuum cleaner.

In general, a vacuum cleaner includes a main body having a suction fan for generating a suction force and a dust collecting part disposed on the suction side of the suction fan to collect foreign substances sucked with the fluid, an extension tube connected to the main body, and an extension pipe connected to the bottom surface. A suction port is provided to suck the fluid and has a suction head coupled to communicate with each other at the end of the extension tube.

Such a vacuum cleaner is provided with a wheel at the bottom of the main body to perform cleaning while moving the main body together with the suction head during cleaning, which is cumbersome to use and generates noise when the suction fan is driven, and the air discharged from the suction fan There is a problem that the relatively high temperature and emits an odor causing unpleasantness to the user.

In consideration of these problems, the main body is installed in an area separate from the user's living room space, and the suction pipes which are in communication with the main body are embedded in each compartment of the room, and an extension pipe connection part is provided which is in communication with the suction pipes in each compartment. In order to clean the compartment, the use of a centralized vacuum cleaner, which allows the extension pipe to be connected to the extension pipe connection unit, enables easy cleaning.

1 is a view showing a state of use of a conventional centralized vacuum cleaner. As shown, the central dust vacuum cleaner is a veranda capable of blocking noise from the room having a suction fan (not shown) for generating a suction force therein and a dust collecting part (not shown) for collecting the foreign matter sucked with the fluid (105). Or a main body 111 disposed outdoors, one end connected in communication with the main body 111, and the other end of the suction pipe 113 embedded in the wall 107 to pass through each space 103 in the room, and The suction head 117 having the suction port, one end of the extension pipe 115 connected to the suction head 117, and the extension pipe 115 to the wall 107 of the space to be connected in communication with the suction pipe 113 The extension pipe connection part 119 formed is provided.

With this configuration, when the user wants to clean the space 103, the user moves to the space 103 to be cleaned with the extension pipe 15 and the suction head 117, and moves the extension pipe 15 to the space 103. The suction fan is driven by operating an operation button formed in the extension pipe 115 while being inserted into and coupled to the extension pipe connection part 119.

When the suction fan starts to drive, foreign matter is introduced into the suction head 117 together with the fluid from the outside, and the sucked fluid and the foreign matter are introduced into the dust collector through the extension pipe 115 and the suction pipe 113. Air introduced into the dust collector is discharged to the outside of the main body 111 through the suction fan, dust and foreign matter is collected in the dust collector.

However, such a conventional centralized vacuum cleaner is mainly intended to clean the bottom surface of the indoor space, and during the process of entering the room through the porch when going home, dust, dirt, etc. attached to clothes or shoes fall on the porch. Not only is the porch very dirty, but there is a problem in that dust separated from clothes and shoes is floated to enter the room and contaminate the room.

Accordingly, an object of the present invention is to provide a suction device for the entrance of the centralized vacuum cleaner, which can facilitate the entrance cleaning, and can suction and remove foreign substances of clothes and / or shoes when entering and exiting.
