Description

HAND DRYER COVERED ΑΝTI SPLASHES AND ANTIBACTERIAL

DESCRIPTION

FIELD AND OBJECT OF THE INVENTION

The invention consists of a hand dryer configured to hygienically dry the wet hands of a user, after washing, avoiding the splashing of water, and comprising a closed chamber with a single opening for the insertion of the hands.

The field of application of the present invention is framed in the sector of automatic cleaning devices, more specifically in the sector of devices for drying hands by pressurized air.

BACKGROUND OF THE INVENTION

According to the World Health Organization (WHO), hand washing is a fundamental hygiene measure for the prevention of infections and to prevent the spread of contagious diseases, since it eliminates bacteria and microbes that may be present on said hands. and, therefore, reduces or prevents the possibility of getting sick, preventing the spread of these microbes and bacteria between people.

Proper hand washing ends with their proper drying, since such drying removes surface moisture, reducing the microbial load and the transfer of microorganisms. This is because the transmission of microbes is more likely to occur from wet skin than from dry skin.

Currently, there are many means of drying hands, being recommended by the WHO those that make use of disposable items, such as paper or wipes, ahead of those that make use of mechanical means, such as automatic dryers. This is due to the fact that many of these types of automatic dryers present on the market suck air from the room in which they are located and produce a turbulent movement of the pressurized air that is applied to wet hands, and in case of an incorrect washing of a user, the spread of particles with bacteria to the environment

SUBSTITUTE SHEET (RULE 26) closer, such as the bathroom floor and walls, even to other users.

In fact, some studies that have carried out inspections of the splashes generated around the automatic dryers of public toilets have determined the flattening of a high concentration of fecal particulars and bacteria harmful to health in the vicinity, as well as in the dryers themselves.

In addition, the polluting factor of the environment must be added, not only with the macroscopic physical particles described but also with volatile particles that are dispersed in the ambient air that is breathed in public toilets.

The most common automatic dryers, installed in public places, are known as low pressure hot air wall hand dryers, which can comprise different types of configurations, but all of them are characterized by generating an open air flow in the room. stay in which they are.

A solution of these dryers to avoid the expulsion of a flow of contaminated air on the user's hands is the use of filters that block the passage of the particles present in the environment to the interior of the dryer, however, they do not prevent said flow of air impacts on nearby particles, generating a turbulent regime, reaching said particles on the user's surface. In other words, with these filters, only completely decontaminated air is achieved in the interior duct of the hand dryer between the inlet and the outlet, thus vanishing the hygienic purpose of the filtering.

There are other automatic dryers on the market that incorporate disinfectant and / or deodorizing means for the skin, which emit a vaporized fragrance to the hot air stream that ends up directly on the user's hands, such as the salio dryer in AU199877349 B2. The purpose of these disinfectant and / or deodorizing means is exclusively directed at the user's skin, but not to disinfect the surface or interior of the hand dryer.

Some hand dryers increasingly present in mocado are known as high pressure wall hand dryers, such as that collected in document US 9060657 B2. This document describes a dryer which is arranged in a V-shape and which comprises two nozzle sections on each of its sides, for the expulsion of

SUBSTITUTE SHEET (RULE 26) Air at high speed over each of the hands to be dried.

The problem with this type of dryers is that the cavity that they present to introduce the hands to be dried is open, so it expels the air towards the user and through its side openings being bounced towards its vicinity. The filter included in its interior only cleans the air in the internal section of the dryer, leaving the clean air through the nozzles. but when it comes into contact with the user's hands, it projects the moisture, not only to the areas near the dryer, but also to the user himself. At the same time, the residual water accumulated in the dryer collector is dispersed by the energy of the pressurized air, volatilizing the undesired organisms in the environment.

Other hand dryers, such as those defined in documents US9982422 B2, US20180251984, and USD768824S, incorporate dryers in the sink itself, which allow avoiding the spillage of water when the user is about to dry off once the washbasin has been washed. hands. The problem with these dryers is that they emit a strong content of air on the surface of the sink, splashing the water that remains on said surface in all directions, spreading and volatilizing possible batteries or microbes that have not been eliminated in the wash.

DESCRIPTION OF THE INVENTION

To solve the aforementioned problems, the present invention describes a hand dryer comprising.

- a frame, preferably formed by metal sheets or plates, or rigid material such as plastic, which constitute the support of the elements comprised inside the frame;

- at least one air flow generator motor, configured to suck air from outside the frame and direct it towards at least one outlet orifice;

- at least one opening, located on a surface of the frame, said opening configured to insert the hands of a user; and

- a drying chamber inside the frame, configured to place the hands of a user inserted through the opening; where ti minus one outlet orifice is located in the opening, preferably on a perimeter thereof, being configured to release the air extracted by the generator motor; and where the drying chamber is configured to collect all the water from the hands of the

SUBSTITUTE SHEET (RULE 26) user, preventing splashes outside the frame and channeling all the air expelled through the air at least one outlet hole into said frame, without air leaks or backflows.

That is, with this embodiment, in the event of an incorrect hand washing in which the bacteria or microbes that may be present on the user's hands have not been eliminated, drying is carried out, there is no expulsion of drying drops. in all directions by bouncing the air against the hands, but are collected by the dryer itself, thus avoiding possible contamination to its surroundings.

The at least one outlet orifice may be a single, narrow and elongated slot in all or part of the opening, or a plurality of slots or holes, distributed throughout the opening, since any of these embodiments is suitable for the operation of the dryer. . Preferably, the outlet port located in the opening releases the strip in a direction towards the interior of the drying chamber. In other words, in the event that air came out without the presence of the hands to be dried, all that air would be directed towards the interior of the drying chamber, preventing its spread to the outside.

In one embodiment, the generator motor directs the air towards the outlet orifice by means of a channeling element selected from:

- a fluid passage conduit;

- a nozzle configured to increase the pressure and speed of the air sucked in by the generator motor and

- a combination of the above.

Preferably, both the generator motor and the channeling element are located inside the frame, thus, no external connection is necessary between said connected elements, as they are all assembled in the same frame.

In one embodiment, the hand dryer comprises three nozzles, connected to the generator motor, that is, the air extracted by said motor is directed towards said three nozzles instead of one.

With this embodiment, the hand dryer comprises two upper openings configured to insert each of a separate user's hands, and

SUBSTITUTE SHEET (RULE 26) preferably in a relaxed position, in the drying chamber, in a direction perpendicular to said openings, and the outlet orifices preferably comprising two slots each located on a perimeter of the openings, and said slots assembled to the nozzles. More preferably, the outlet ports comprise four slots, two for each opening. In this way, the distribution of the tire expelled through the grooves, coming from the generator motor, is increased in pressure, speed and better distributed in each hand.

In this embodiment, to allow adequate introduction of the hands into the upper openings, they comprise an oblong shaped section with an inner end that is wider than an outer end. Thus, as the hands are slightly wider where the thumbs meet, the shape of the openings adjusts to the cross-section of the hands and their natural position. Furthermore, in a preferred embodiment, the openings comprise a conical shape that facilitates the introduction of the hands into the interior of the drying chamber, and makes it difficult for drops to escape from the hands when drying occurs, the sections being slightly oblong. Inclined, symmetrically, with respect to the center of the dryer.

In one embodiment, the dryer comprises an inlet filter HEPA (High Efficiency Particutate Air), anti-bacteria, anti-virus and anti-allergen, configured to filter the air drawn in by the generator motor from outside the frame. In this way, the air that is directed to dry the user's hands is clean and does not contain impurities or particles as they have been retained by the filter. In the same way, the inlet filter fulfills the functions of preventing obstructions in the suction motor, as well as in the nozzles and in the outlet ports.

In one embodiment, the hand dryer comprises a suction motor connected to a fan, said motor located in a suction chamber, which is located inside the frame. The suction motor is configured to suck the air released through the at least one outlet orifice, lead it through the drying chamber to the suction chamber through a lower channel of an intermediate plate that separates said chambers, and expel it to the outside of the frame.

In this way, all the air expelled through the outlet holes is sucked in by the suction motor, without allowing said air to escape directly outside the

SUBSTITUTE SHEET (RULE 26) frame of the hand dryer through the upper openings, thereby preventing the release of bacteria or micro-organisms from drying into the environment.

In a preferred embodiment, both the generator motor and the vacuum motor are electric, so that the generator motor comprises a high-frequency intermittent pressure system of air to improve the speed of drying hands, while the vacuum motor operates continuously.

To prevent any particles present on the hands from being expelled by the air released through the outlet holes, the dryer is configured so that, when introducing the hands through the upper openings, the suction motor is activated first than the generator motor, thus The aspiration occurs before the blow of the outgoing air through the outlet holes towards the hands.

In one embodiment; the hand dryer comprises a HEPA, antibacterial, antiatorgenic and antiatergenic outlet filter, configured to filter the air expelled by the suction motor. With elto it is avoided that any particles, bacteria or microbes are expelled from the interior of the hand dryer, expelling only clean air. In other words, the spread of unwanted organisms in the environment is avoided, maintaining hygiene in the location where the dryer is located.

In one embodiment, the hand dryer comprises a disinfection means comprising at least one disinfectant fluid reservoir, preferably located inside the frame, and at least one disinfecting fluid spraying or spraying means configured to expel said fluid over the opening.

Preferably, the disinfection means comprises two disinfectant fluid reservoirs, as well as two spraying means, one for each opening. Said tanks are located in an upper part of the frame and can be filled with disinfectant fluid through a side opening,

This automatic cleaning and disinfection means acts on the surface of the upper openings, being the most susceptible to being touched by the user, as well as the interior of the drying chamber, since, with the dryer in the operating position, the fluid falls through these openings to the drying chamber due to the effect of gravity, which

SUBSTITUTE SHEET (RULE 26) Maintains hygiene in all critical areas of the hand dryer.

In one embodiment, the hand dryer comprises at least one position detection sensor, preferably located on the upper surface of the frame, next to the at least one opening, said sensor configured to detect the user's hands inside the The opening. Most preferably, the hand dryer comprises two detection sensors, one for each hand and opening.

In a preferred embodiment, the dryer is installed in such a way that, upon detecting the detection sensor from the user's hands, the suction motor is activated and then the generator motor, causing the hands to dry.

In the same way, when the detection sensor does not detect the presence of hands inside the openings, the spraying means can be activated, having a programmed frequency, being able to be activated after each use of the dryer, or after a number of previously determined uses.

In a non-preferred embodiment, the spraying means can be activated at the same time as the motors, which allows a greater distribution of the disinfectant fluid over the hand dryer.

In one embodiment, the hand dryer comprises lighting means configured to illuminate the interior of said drying chamber. Said lighting means may comprise one or more LED lights or other electrical source lighting means. This internal courtesy light in the drying chamber makes it possible to illuminate the dark area that the user uses when drying their hands, making it easier to use.

In one embodiment, the hand dryer comprises an ultraviolet radiation medium located inside the frame. Said medium can generate ultraviolet light inside the drying chamber, inside the suction chamber and in the air outlet filter. That is to say, where the unwanted organisms accumulated from the drops of the user's hands can accumulate, they tend to be eliminated by said radiation.

In one embodiment, the hand dryer comprises a suction grille of the generator motor and an ejection grille of the suction motor that configure said grids, to

SUBSTITUTE SHEET (RULE 26) Exchanging air between the inside and outside of the hand dryer frame. In other words, through said grilles, air is allowed to pass between the inside and outside of the frame, but only when the motors are activated.

In one embodiment, the hand dryer comprises a liquid outlet in a lower part of the frame, which is connected to an external drain. In non-preferred embodiments, the water from the drying of the hands can accumulate in the lower part of the suction chamber, since normally said water does not comprise large volumes, although said suction chamber can also comprise a hole for emptying it. manual, but preferably, all the drying water is directed to an external drain, to avoid contact with any user.

In one embodiment, the hand dryer comprises a thermal resistance configured to increase the temperature of the air drawn by the generator motor directed towards it minus an outlet port. Hot air has a higher hand drying efficiency than cold roast.

In one embodiment, the hand dryer comprises an automatic hand washing system by spraying a selected element between disinfectant, water, detergent, soap and a combination of the foregoing, said system located in the drying chamber. The operation of this system consists of not requiring hand washing prior to drying, introducing the user's dry hands inside the drying chamber, receiving a spray of cleaning liquid, and subsequently drying.

In the case in which the dryer includes this automatic washing system and the disinfection means, the disinfectant fluid in the reservoir can be used for disinfection not of the dryer, but also of the hands themselves.

In one embodiment, the frame comprises.

- an upper plate where the two openings of the drying chamber are located;

- two side plates, symmetrical and parallel, located on the sides and oriented perpendicular to the upper plate;

- a back plate perpendicular to the side plates and to the upper plate;

PREFERRED DESCRIPTION OF THE INVENTION

As can be seen in Figures 1 and 2, the preferred embodiment of the invention consists of a high pressure air hand dryer (1), configured so that all the air used for drying, as well as the fluid from the The hands coming from the wash are collected inside said dryer (1) without generating a splash, rebound or draft of the air towards the outside. In this way, it is avoided that drying by means of air pressure can contaminate the environment or other users with possible bacteria or microorganisms that may not have been dimmed by washing.

The hand dryer (1) comprises a frame (4) consisting of a support or structure formed by a set of metal sheets. More specifically, the frame (4) comprises an upper plate (41) oriented horizontally, two

SUBSTITUTE SHEET (RULE 26) side plates (42). Perpendicular to the upper plate (41), oriented vertically, a rear plate (43), also perpendicular to the upper plate (41) and to the side plates (42). and a front plate (44) of a cylindrical curved shape that connects the upper plate (41) with the rear plate (43). Thus, the frame (4) of the hand dryer (1) comprises a shape similar to that of a quarter of a cylinder.

This configuration allows the hand dryer (1) to be easily attached to a lower surface of a sink table or to a wall, facilitating access to the user after washing their hands.

As can be seen in Figures 5A-5D, inside the frame (4) the dryer also comprises an intermediate plate (12) perpendicular to the upper plate (41) and to the side plates (42), which divides the interior of the frame (4) in a drying chamber (6) and a suction chamber (10).

In this way, the operation of the hand dryer (1) is based on the introduction of the user's hands in two upper openings (5, 5 ') located in the upper plate

(41 :).

As can be seen in figure 3, the upper openings (5, 5 ') have an oblong shape, with a somewhat larger opening at the inner central part than at the ends, since said upper openings (5, 5) are adapted to the normal position and morphology of a user's hands, being slightly wider where the thumbs meet. Furthermore, as can be seen in Figures 1 and 2, the upper openings (5, 5 ') comprise a conical shape that facilitates the introduction of the hands inside the drying chamber (6). This shape also allows the collection of the water sprinkles coming from the user's hands into the dryer chamber, thus avoiding the puddling of the upper part. In addition, this morphology in turn favors the action of disinfection by means of the liquid product, which, when applied, slides over the entire water collection surface into the body of the dryer, thus allowing the controlled drainage of the liquids in this area. .

Once the user introduces his hands into the openings (5, 5 '), he places them in the drying chamber (6), and two position detection sensors (7) located next to the upper openings (5, 5') detect hands and activate a suction motor (9) and a motor

SUBSTITUTE SHEET (RULE 26) generator (2) in that order.

The generator motor (2) is located in an upper part of the frame (4), resting against the upper plate (41) and the rear plate (43). This generator motor (2) draws in air from outside the frame (4), through a suction grille (15) located on the rear plate (43), which is filtered by an inlet filter (8) HEPA and is aimed at fresh tuff that increase its pressure and speed, and release it through outlet holes (3, 3 '), which consist of four slots, two for each hand and opening (5, 5'), so that the drying is as efficient as possible. Furthermore, these grooves are located in the perimeters of the upper openings (5, 5). That air released under high pressure hits against the damp hands coming from! washing, in an inclined direction with respect to the upper plate (41), towards the interior of the drying chamber (6), to prevent the rebound of air against the hands from leaving said chamber (6).

The suction motor (9) is located in the suction chamber (10), below the generator motor (2), leaving a space below for the collection and accumulation of liquid. This suction motor (9) expels the air that is inside the suction chamber (10) through an expulsion grille (16), which is located on a side plate (42), That air before If expelled, it passes through an outlet filter (13) that prevents any type of unwanted particle from leaving the dryer (1), expelling only clean air.

The air found in the suction chamber (10) comes from the drying chamber (6) since both chambers (6, 10), from being separated by the intermediate plate (12), are communicated by a channel bottom (11) of it. Said channel (11) allows the air from the drying chamber (6) introduced by the generator motor (2), through the slots, to be whipped up in its entirety by the suction motor (9), while the drops of water introduced through the upper openings (5, 5 ') slide down the front plate (44) to the lower part of the suction chamber (10) being withdrawn from the dryer (1) through a drain connected to the network.

The hand dryer (1) also comprises a disinfection means shown in Figures 5A-5D. This means comprises two tanks (17, 17 ') of disinfectant fluid, such as soap, alcohol, bleach, gel, detergent or a mixture of the above, located on the sides of the generator motor (2). These tanks (17, 17 ') can be filled

SUBSTITUTE SHEET (RULE 26) of fluid through a side opening located in the side plates (42) and are connected to two spraying means (14) located in the upper plate (41). These spraying means (14) comprise a nozzle that sprays the fluid from the tanks (17, 17 ') onto the openings (5. 5'), and due to their conical geometry, the disinfectant fluid slides through them. towards the interior of the drying chamber (6) and up to the suction chamber (10), cleaning the surface through which it is dragged. In this way, the entire surface that the user can touch with their hands is disinfected.

The disinfection means can be activated when the generator motor (2) and the suction motor (9) are not running, that is, when the hand dryer (1) is not drying hands.

Once the position detection sensor (7) does not detect any element inside the upper openings (5, 5 '), the spraying means (14) can release the disinfectant fluid, these being programmed for operation after one or more uses of the dryer (1), and / or as a function of a frequency of times.
