Abstract

The invention relates to an extrinsic element for distributing air throughout an entire room in a continuous and non-uniform manner, preventing certain health problems that can be caused by these systems when the flow of air is blown directly and uniformly at users. The element is surface mounted in the unit itself, receiving therein the air directly leaving the outlet slot. The element redirects the flow of outgoing air and redistributes same throughout the room in which the element is installed. The element is made of a light and flexible material, like paper, in order to permit the damping of the impact caused by the flow of air originating at the outlet of these systems.

STATE OF THE TECHNIQUE.

The main objective of the air conditioning diffusers that constitute the state of the art is the deviation of the air flow in various directions to avoid the direct impact on people, trying to avoid their harmful effects on health. Among these effects are inflammations in the muscles, cooling, torticollis, cervical pains, low back pain, eczema, pruritus, reddening of the skin, etc. The state of the art comprises different types of air diffusers, depending on their geometry and operation, the most common being circular, rectangular or square, rotational and linear, whether fixed or mobile vanes.

Some examples of these diffusers are described in the following patents: Warren R. Hedrick, 1976, US Patent 3,948,155; Schroeder et al, 1981, US Patent 4,266,470; Wilson et al., 1983, US Patent 4,366,748; Fran Sodec, 1991, US Patent 5,045,379; Craig S. Ludwig, 1993, US Patent 5,192,348; Craig S. Ludwig, 1995, US Patent 5,454,756. These systems, although fulfilling their objective, are not entirely effective when applied as redistributing elements of the air, in a continuous and non-uniform way, throughout the room.

In addition to the referenced patents, there are a number of records that attempt to minimize the problems of conventional diffusion systems. Thus, for example, European application number 97903091.3 (ES 2182023,) describes a fabric air diffuser for environmental control systems for commercial and residential buildings. The German patent application of Braun Jean, 1990, DE3909497 refers to the arrangement of ducts and the mouths for directing or distributing the air in the rooms or enclosures using textile material. On the other hand, in patent BR 32403/69 a metal diffuser with holes for redistributing the air through the room is described. In a different way, Randy W. Roberts, 2012, US Patent 2012/0079945 uses a plastic cover with round slots to dispense air freshener throughout the room for air records of floors, walls and ceilings. The Chinese patent application of Anchun Shao, 2010, number CN201387088 refers to a strong and durable diffusion system made of plastic for ceiling air conditioning systems.

In short, the state of the known art is composed of numerous inventions of air diffusers for centralized air conditioning systems, generally mounted on the ceiling, which do not specifically solve the problem posed by standard Split air conditioning equipment and murals, arranged in surface mounting and installed in small rooms. DESCRIPTION OF THE INVENTION

The object of the invention is an extrinsic element to standard indoor air conditioners, split type and murals, whose objective is to distribute the air, in a continuous and non-uniform way, throughout the room, avoiding certain health problems , such as inflammations in the muscles, cooling, torticollis, cervical pain, low back pain, eczema, pruritus, reddening of the skin, etc., which these devices usually produce when the air flow directly and uniformly affects the users.

This element called "Accessory Element of Distribution and Redirection of Air Conditioning Flow, hereinafter: EADRECA", consists of a sheet of light and flexible material, such as paper, consisting of a central body of rectangular shape, with various openings, and two adhesive bands on its two wider sides.

The EADRECA must be placed on the air outlet located on the outside of the air conditioner, being fixed to the housing of the same by means of the adhesive bands that it has in two its ends, which allow its easy assembly and disassembly.

The central body, manufactured using a lightweight material such as paper, makes it ideal for absorbing the blow of the air mass at its free exit, acting as a load absorber.

The openings that the central body of the EADRECA presents are arranged in rows all over its surface. Its determined disposition tries to generate an effect of irregular distribution of the conditioned air by the stay, avoiding that the flow of air affects of a direct and uniform form on the people who live there.

Once placed on the air conditioner, when it is in the rest position, the EADRECA acquires a geometry similar to a paper bag, being subject to the air conditioner by its wider sides, its other two sides remaining without support.

When operating the air conditioner with the EADRECA mounted, the air produced by it causes the EADRECA to inflate as if it were a balloon, leaving part of the air through the openings of its body and the rest by its two sides not attached to the housing of the air conditioner. The openings, together with the free lateral outlets, prevent the return of the air to the equipment, which would cause defects in the efficiency of the device until it reaches a malfunction.

In order to prevent most of the air generated by the air conditioner from directly impacting the people who inhabit the room, the EADRECA presents its larger openings in the part that, when operating the air conditioner on which it is installed, it is suspended pointing towards the top, while the smaller openings are those that are in the part that is pointing down.

The physical effect created by the EADRECA is twofold, on the one hand, it allows to direct the output air flow and, on the other hand, to distribute it to a greater extent, through the highest area of the room where the unit has been installed.

The EADRECA is especially indicated for reduced stays where the effects of the direct impact of the free flow of air on the human body could generate serious physical problems. Its simple configuration allows it to adapt to all types of commercial air conditioners. Likewise, it allows different designs for its perfect decorative integration, as well as the incorporation of scented effect through the incorporation of aromatic substances.

MODE OF EMBODIMENT OF THE INVENTION.

The EADRECA can preferably be made of paper, and it can also be made of any textile material, plastic, etc., sufficiently flexible and lightweight so that it is suspended by the mass of air that a conventional air conditioning apparatus gives off.

It is an extrinsic element, easy to place and remove, thanks to the adhesive bands that it has on its two wider sides, specifically on the upper and lower sides. Its adhesive bands allow its easy assembly to the air conditioner housing, as well as its disassembly so that it sets the summer period can be removed to use the heat pump so that it acts on the entire winter stay.

EADRECA measures should be those that cover at least the width of the air outlet opening of a standard air conditioner. As an example, these measures could be 800x400 centimeters. The configuration of the openings on the body of the EADRECA, greater in its upper part and lower in the lower part, intends that the air outlet, once cushioned in its interior, be greater by the upper part and smaller by the lower part. The physical effect achieved is represented in Figure 3.

This effect is achieved, for example, by making the sum of the hollow surface, constituted by the openings of the first row of the upper part greater than that of the second and, the latter than the third and so on until the last row on the bottom.

A specific case of the configuration of the openings in the body of the EADRECA consists in applying a decreasing ratio, estimated at a rate of 10% lower the second row with respect to the first, 50% the third with respect to the first, a 75% lower than the fourth on the first and so on until reaching the last row.

INDUSTRIAL APPLICATION

The level of industrial application of this invention is high, since the manufacture of EADRECA is simple and implies a low manufacturing cost. Its low manufacturing cost makes it a single-use and economical element so that it can be easily acquired, it is indicated for each seasonal period.

The materials, shape, size and arrangement of the elements will be subject to variation, provided that this does not imply an alteration to the essentiality of the invention.

The terms in which this report has been described must always be taken broadly and not limitatively.
