Description

Improvements in the suction hose connection terminal for centralized suction equipment.

OBJECT OF THE INVENTION

The purpose of this certificate of addition is to present a series of improvements in the suction hose connection terminal for centralized suction equipment consisting of optimal external and internal measurements both in the suction pipe and in the tubular housing of the counter-turning , so that it is possible to install central vacuum equipment on walls, partitions, walls or the like with thicknesses of 46 mm., also obtaining minimum load losses.

BACKGROUND OF THE INVENTION

At present, the central vacuum systems for cleaning compete with traditional vacuum cleaners since, despite being more complex and expensive systems, they offer a number of advantages by having a central vacuum unit separate from the rooms to be cleaned and a network of aspiration that theonine in different terminals. The teoninals for the connection of the suction hose that currently exist are formed by a contralQma connected to a network of conventional suction pipes approximately 51rnm. in diameter, which is arranged inside the wall of approximately 75mm. of thickness; these terminals also constitute an outlet on the surface to which the hose is connected and where the electrical connection of the suction system cables is made. In this way, when the suction hose is connected to the socket, the metal termination of said suction hose comes into contact with said socket and closes an electrical connection that causes the automatic aspiration of the aspiration system. The terminals with the electrical connections in the socket present a series of problems such as, the excess length of wiring necessary to be able to manipulate the socket and make the connections to it, and that at the time of assembly they are piled up, pinched or hooked these causing deterioration and possible installation failures.

In order to solve these problems, the invention patent P200702607 was applied, in which the first aspect of the invention refers to a system that achieves a terminal for the connection of suction hoses of centralized suction equipment avoiding the inconveniences existing in prior state of the art systems.

For this system to be completely optimal, the suction pipe network consists of new exterior and interior measures so that the aspiration system can be located in homes, offices, shops or similar that have partitions with thicknesses of 46 mm., also achieving minimum load losses. Thus, the installation of central vacuum systems is no longer limited to partitions with large thicknesses, in which only tubes with 51 mm could be introduced. in diameter, but with the optimal external measurements of the oval section object of this register, a step goes beyond allowing the installation of this type of systems to all types of constructions, also obtaining minimal losses of loads in oval sections that up to The date was not obtained.

Below is a detailed description of the invention that completes these general ideas introduced at this point.

In order to alleviate the above-mentioned problems, improvements in the suction hose connection tenninal for centralized suction equipment are presented, consisting in the optimization of some measures in the connection pipes and in the tubular housing of the counter-turner, which reside in external measurements with oval section rectangular rounded section estimated between [34mm. ± 1 Ornm.] x [69mm. ± IOmm.], and optimal internal measures with oval section rectangular section estimated between [30mm. ± IOmm.] x [ 65mm. ± lOmm.]. In such a way, that the installation of centralized suction systems is possible in partitions, walls or similar with 46mm profiles.

Thus, with the new optimal measurements of the connection pipes, pipes with a more compact design are obtained, which can also be arranged in pipe crossings with other systems, reduced spaces between walls and plasterboard partitions, among others.

Another detail of the invention is the minimum loss of load that is obtained in suction systems with oval sections of this type, in which is attached as an example the Test A set out below in Figure 6 and in the section called description of the drawings

DESCRIPTION OF THE DRAWINGS

20 As can be seen in the attached figures, the improvements introduced in the connection of the suction hose connection for centralized aspiration equipment "consist in the optimization of some measures in the connection pipes (7) and in the tubular housing of the against socket (2), which reside in external measures (a-a ') with an oval section estimated between [34mm. ± IOmm. 1 x

25 [69mm. ± IOmm.], And optimal internal measurements (b-b ') with an oval section estimated between [30mm. ± lOmm. 1 x [65mm. ± IOmm.]. In such a way, that the installation of centralized suction systems is possible in partitions, walls or similar with 46mm profiles.

30 Thus, with the new optimal measurements of the connecting pipes (6) pipes with a more compact design are obtained, which can also be arranged. Another detail of the invention is the minimum loss of load that is obtained in the suction systems with Oval sections of this type, in which is attached as an example of Test A (Fig. 6) as set out below:

Egg A

In order to check the performance in an installation with the improvements introduced in the connection of the suction hose connection for centralized aspiration equipment, an installation with 7 suction inlets was proposed

(102) Y40m. of pipe.

To check the loss of load of the installation made with pipe of estimated external oval section between [34mm. ± IOmm.] X [69mm. ± 1 Omm.], And estimated internal oval section between [30rnm. ± 1 Ornm.] X [65rnrn. ± IOrnrn.], Depression measurements were performed with a vacuum gauge (101) at the entrance of the central vacuum (100).

Point 1 -7 1000mm. H20

Depression measured at the intake of the suction unit (100) (Maximum depression): 2 100mm. H20 Point 1: Measurement in the farthest outlet from the central vacuum.

The load loss would be: p ~ 1000rnm 1120 (48%)

As a consequence, the result of the loss of load is totally acceptable for a central vacuum system, not affecting the performance of the Once the nanowell of the invention has been conveniently described, it is stated for the appropriate purposes that it is not limited to exact details of this exhibition, if not the opposite, it will introduce the modifications deemed appropriate, provided they are claimed below.
