Description

Hand dryer.

Object the invention

The present invention relates to a dryer hands, of the type that comprise: a housing, a bedroom drying, integrated into the housing, for the insertion of the hands, means for the delivery of air at room temperature at high inward speed of the drying chamber, detectors presence or proximity for automatic dryer activation when the user puts his hands in the drying chamber, a electronic control card, a conduit for the evacuation of the  water drying chamber detached from the user's hands during drying, and at least two groups of air vents arranged on opposite, anterior and posterior surfaces of the drying chamber, each of said groups comprising Several exits.

Background of the invention

In this section, the existence of utility models 200401898, 200402353 and 20050359 thereof Applicant of the present invention.

These utility models describe some hand dryers that generally include: a box or housing, a cavity or drying chamber integrated in the housing of the dryer and in which the hands are inserted to realize its drying, means for high-speed air delivery and at ambient temperature towards outputs arranged in the facing surfaces of the cavity or drying chamber and about proximity sensors that activate the air supply means when they detect the user's hands inside the bedroom.

The dryers object of the mentioned models of utility project air at high speed and temperature environment over the user's hands causing the water to sweep towards the lower part of the bedroom where a water drain pipe to a tray or container located inside the housing.

In this way the water detached from the hands of the user by air at high speed and at room temperature projected on them does not fall to the ground but accumulates in the inside of said tray or storage tank.

The accumulation of water in said tray or inner tank although it prevents water from falling to the ground and can splashing the user's clothes, presents some inconveniences of use being of highlighting of a part that in the case of a intensive use of the dryer the accumulated water can overflow with  the tray also falling to the ground and, other than water  accumulated in the tray favors the accumulation of dirt, being able to decompose producing bad smells and conditions Poor hygienic

Description of the invention

To solve the aforementioned problems, devised the hand dryer object of the present invention, which presents constructive particularities oriented to allow the immediate evaporation of the water evacuated from the drying chamber and the expulsion outside the steam, preventing the retention of water inside the dryer and thus preventing the water I can overflow and fall outside.

The hand dryer object of this invention, being of the type mentioned above is to say that they release the water from the user's hands, once introduced these in the drying chamber, by projection on the same air at high speed and at room temperature, presents the particularity of incorporating a device for evaporation of the water coming from the drying chamber, including said device a controlled low power electrical resistance by the electronic control card and a fan that drives the steam produced outside the housing avoiding the retention of water inside the dryer.

In accordance with the invention the resistance electrical is housed inside a tubular body arranged in a substantially horizontal position inside the housing and which has a top connection mouth of the duct in evacuation of water from the bedroom of dried

The fan mentioned above and responsible for driving steam out of the housing produced by the electrical resistance is mounted on one of the extreme mouths of the tubular body, meeting a conduit connected to the opposite mouth of said tubular body outlet by which the steam is conducted out of the Case.

In this way the water coming from the bedroom of drying access through the interior of the evacuation duct to the inside the tubular body coming into contact with the resistance electric responsible for evaporating it, with steam being driven towards the outside by the fan mentioned outside.

Optionally and in order to optimize the operator device performance is expected that the resistance can be thermally housed in a jacket conductive and provided with diffuser fins, also providing the tubular body in the upper water inlet mouth of a sieve or grid for separation into particles or fine drops of the water from the drying chamber. This way you get that the water particles separated by the grid or sieve are distributed by the air flow generated by the fan on the diffuser fins performing evaporation practically instantaneous and the steam produced being driven, by itself air flow, outward.

As mentioned above the resistance operation will be controlled by the own electronic control card, with the help of a probe temperature, said electronic control card performing the resistance disconnection when detecting a temperature greater than a predetermined value and that is reached when there is no water inside the evaporator device.

Preferred Embodiment of the Invention

In the exemplary embodiment shown in the figures you can see a dryer provided with a housing (1) in which is defined a drying chamber (11) for the introduction of the user's hands, being arranged in the facing surfaces of said chamber (11) groups of nozzles (21) through which high pressure air exits and ambient temperature supplied by a turbine engine (2).

In said drying chamber (11) are arranged presence or proximity detectors (31) that are are connected to an electronic control board (3) responsible for automatically activating and deactivating the turbine engine (2).

The projected air through the groups of exits (21) releases water from the user's hands, falling towards the bottom of the drying chamber (11).

Said drying chamber (11) is provided with a evacuation duct (4) which, according to the invention, conducts the water to an evaporation device (5) located in the inside the housing (1), said device (5) being the responsible for evaporating the water that accesses it and expelling it outside the housing (1) in the form of steam.

The mentioned evaporator device (5) it comprises a tubular body (51) disposed in a lying position in the inside of the housing (1) and provided with an upper mouth (52) for connecting the evacuation tube (4) responsible for driving the water from the drying chamber (11) into said tubular body.

In the tubular body (51) it is mounted internally an electrical resistor (53) connected to the plate control electronics (3). Outwardly over the ends opposite the tubular body (51) are mounted a fan (54) responsible for displacing the water evaporated by the resistance (53) to the outside and a pipe angled (55) by the inside of which the steam is displaced towards the outside of the housing (1).

Optionally and as shown in the example of embodiment of figure 6 the resistance (53) can be found housed in a thermally conductive jacket (56) provided with diffuser fins (57) to optimize the performance of the resistance (53).

In this case it is planned that the upper mouth (52) through which access to the inside of the body (51) is the water evaporate incorporate a grid or sieve (58) for separation in fine drops of water from the drying chamber, which facilitate evaporation when these drops fall on the fins (57).

Once the nature of The invention, as well as a preferred embodiment, is for the appropriate purposes that the materials, form, size and arrangement of the elements described may be modified, as long as this does not imply an alteration of the essential features of the invention claimed in continuation.
