Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a centralized dust collection device in which a dust collection device main body and a plurality of outlets are connected through a conduit.

BACKGROUND TECHNOLOGY Conventionally, in a centralized dust collection device having one dust collection device main body, outlets installed in several parts of a room, and pipes connecting the outlets and the main body, the above-mentioned Each of the multiple outlets could be opened independently.

Problem to be Solved by the Invention Therefore, when one outlet is used for cleaning, the lid of the other outlet can be opened and closed freely, so two or more outlets are used for cleaning. The lid may be opened due to simultaneous use of the mouth or play by children, resulting in a reduction in dust suction power, resulting in problems such as uneven suction and dust clogging in the pipes.

The present invention solves the above-mentioned nine problems by using any outlet and utilizing the fact that the inside of the pipe becomes negative pressure when other outlets are closed. The present invention provides a centralized dust collection device equipped with a mechanism that prevents the lid of the mouth from opening.

Means for solving the problems In order to solve these conventional problems, the present invention
The dust collecting device has a main body, a pipe line for transmitting dust suction power, a lid that rotatably closes the front surface of a cylindrical part for connecting a cleaning hose, and an insertion port connected to the end of the pipe line. , a bellows-like member whose inside communicates with the inside of the cylinder is provided between the front cover part of the insertion port and the cylinder, and this bellows-like member has a mechanism that shrinks and responds when the pressure inside the cylinder is negative. A sliding member is provided for closing the operation window of the lid.

Operation In the above-mentioned structure, when the loading is turned over, the bellows-like member contracts in the unused insertion port, and the sliding body that responds to this contracts closes the operation window of the lid.

Therefore, the lid cannot be opened. Furthermore, the operating state of the device can be known by confirming that the operation window is closed by the sliding member. Embodiment An embodiment of the present invention will be described below with reference to the drawings.

Figure 1 shows an outline of the central dust collection device.

Reference numeral 1 denotes a main body of the dust collector installed in one place indoors, and it communicates with an outlet 4 fixed at an arbitrary position on the floor or wall 3 through a conduit 2 laid under the floor or in the wall. ing.

Reference numeral 5 denotes a front cover portion of the insertion port 4, and numeral 6 denotes a rear cover portion, which are fixed by screws 7 while sandwiching the wall surface 3, and constitute the insertion port 4.

Further, the rear support portion 6 is fixed to a stud (not shown) of a house structural material or the like. A cylindrical portion 8 into which a cleaning hose fits is formed integrally with the front cover portion 5, and a packing 9 is provided between the cylindrical portion 8 and the rear cover portion 6 to form an airtight structure.

Reference numeral 10 denotes a lid that closes the cylindrical portion 8, and is rotatable by a shaft 11 provided on the front cover portion 5.

12 is an airtight sealing material, which is pasted on the inner surface of the lid 10;
It functions to maintain airtightness when the lid 10 is closed.

Reference numeral 113 denotes a bellows-like member formed to have an elastic shape, and is located in contact with the outside of the cylindrical portion 8 , and its interior communicates with the inside of the cylindrical portion 8 through the through hole 14 .

Reference numeral 15 designates a window in a space 16 provided in the front cover portion 5 so that a fingertip can be inserted to open the lid 10.

The bellows-like member 13 is located immediately behind the window 15, and has one end in contact with the outside of the cylindrical portion 8 as described above, and has a sliding member 17 fixed to the other end, so that it is not affected by its expansion and contraction. The sliding body 17 moves accordingly. A display board 18 is attached to the sliding body 17 so that the display can be seen when the sliding body 17 closes the window 15. In the above-mentioned concentrated dust collection device, when none of the outlets 4 are used,
As shown in the figure, the bellows-like member 13 in each insertion port 4 stretches due to its own elasticity, and the sliding body 17 is pushed to create a space 16, so that the bellows-like member 13 can be seen through the window 15. It's getting old.

Since you can put your fingertips into the space 16, you can easily pull the top end of the lid 10 with your fingertips to open the lid 10 and remove the cleaning hose. can be inserted. In this way, when one outlet is in use for cleaning, the conduit 2
Since all are in communication, the cylindrical portions 8 of the other insertion ports 4 are under negative pressure. On the other hand, the bellows-like member 13 provided outside the cylindrical portion 8 is
Since the inside thereof communicates with the cylindrical part 8 through the through hole 14, if the inside of the cylindrical part 8 becomes negative pressure, it will shrink as shown in FIG. 4. At this time, the sliding body 17 fixed to the bellows-like member 13 closes the window 15, leaving no space 16 for inserting the fingertip. On the other hand, the lid 10 with the airtight sealing material 12 pasted on its inner surface is pressed by the atmospheric pressure due to the negative pressure z inside the cylindrical portion 8 and is in close contact with the lid 10 . Therefore, when one outlet is being used for cleaning, the lid 10 of the other outlet 4 cannot be opened easily. When the main body of the dust collector is not moving, this insertion port 4 has a space at the window 15 of the front cover part 5 and the lid 10 can be opened easily, but one of the insertion ports is in use. In this case, the window 15 is blocked from inside by the sliding body 17, and the lid 10 cannot be opened. Therefore, it is possible to prevent the simultaneous use of the outlet and the opening of the cover of another outlet, thereby preventing a decrease in the dust suction power and the concomitant clogging of the conduit with dirt.

Further, in the above embodiment, a display board 18 is provided on the sliding body 17, and by putting characters such as "in use" on this display board, or by using a color such as red for identification, Displaying that another outlet is in use can increase the effectiveness of the protective layer to prevent malfunctions. Effects of the Invention As described above, the present invention includes a dust collecting device main body, a pipe line for transmitting dust suction force, and a lid that rotatably closes the front surface of a cylindrical part for connecting a cleaning hose. A bellows-shaped member is provided between the front cover part of the socket and the cylindrical part, and the bellows-shaped member that senses the negative pressure inside the cylindrical part and responds to it, and a slider fixed to the bellows-shaped member. By displacing the moving body in such a way as to make it difficult to open the lid, it is possible to prevent a reduction in dust suction power and dirt clogging due to simultaneous use of the receptacles or accidental opening of the lid.

It also allows you to know the operating status of the device, making it very easy to use.
