Definitions

  • the invention relates to a device which has been specifically devised to eliminate bad smells from inside a toilet, when the toilet is used.
  • the device subject hereof has been devised and structured so as to absorb air from inside the toilet, consequently carrying away bad smells, and newly returning the air to the environment once the air has been duly filtered and deodorised.
  • the device is structured in such a way that the entire unit forms a body which may be fixed on a wall, or be kept simply supported on the floor, and located at all times collaterally to or behind the toilet to which it is applied.
  • Spanish utility model application number 9500551 describes a device for eliminating smells from a toilet, constructed with an electric motor fan fitted with a support which may, depending on the specific conditions of each toilet, enable said support to be fixed to the actual toilet, on the floor or on the wall.
  • the motor fan has an axial inlet and a tangential outlet, the outlet having an expeller nozzle coupled to it which may house within a filter, specifically an activated carbon filter.
  • a cylindrical bushing is coupled to the motor fan inlet which extends said inlet vertically upwards, the bushing in turn having a telescopically coupled aspirating nozzle which, with the assistance of an o-ring seal, may adjust its position in height with respect to said bushing, in order for a radial, lateral and rather flat extension constituting the nozzle as such, to be located in each particular case precisely level with the mouth of the toilet, to be arranged specifically between such mouth and the classic ring or annular seat.
  • the structure described is complemented with a seal designed to be fixed to the underside of the annular seat, establishing a perimetric seal between the seat and the toilet, which is only discontinued in a small sector where the flat extension of the aspirating nozzle is coupled.
  • the device of the invention which is based upon the structure described in the utility model referred to in the previous paragraph, offers a number of innovations which result in respective advantages, such as a greater user safety, a greater reduction of the device as a whole which is furthermore more compact and linear insofar as its aesthetics is concerned, and indeed a more rational structure of the device as such.
  • the device is conveniently particular in that the transformer is arranged inside the actual housing of the motor driving the fan, right under such motor, and supported by dividers projecting from the bottom of the housing, allowing a bottom venting which will logically favour cooling of the actual transformer.
  • dividers are provided arranged out of phase with each other at the outlet mouth for purified air, forming a labyrinth which makes the inflow of foreign particles or objects towards the fan difficult.
  • this second embodiment of the device is also characterised because the general housing therefor is formed by two axially couplable parts, one housing the transformer and the motor, and another one housing the fan and the actual activated carbon filter.
  • this second embodiment of the device of the invention provides it with an optimum compactness which allows it to be supported directly on the floor to discharge its function and be located next to or behind the toilet proper, and all the elements are moreover duly protected and concealed, whence it is much more decorative and has a better aesthetic appearance.
  • Figure 1.- Is a perspective exploded view of the device for eliminating smells from a toilet, made in accordance with the object of the invention.
  • Figure 2.- Is a perspective view of the same unit of the preceding figure, duly mounted and coupled to a toilet.
  • Figure 3.- Is a cross-sectional close view of the device, showing the path of the air from inside the toilet until it newly reaches the outside through the expeller nozzle.
  • Figure 4.- Is a general perspective view of a second embodiment of the device applied to the relevant toilet, shown in phantom.
  • Figure 5.- I is a close view of the outlet mouth for purified air included in the device shown in the preceding figure, clearly showing the out-of-phase dividers forming a labyrinth that prevents the inflow of dirt, objects or any type of foreign bodies which might affect the fan, which is located facing such inlet.
  • Figure 6.- Is a sectional close view of the lower portion of the housing of the device, showing the bottom dividers provided to support the relevant transformer.
  • the device for eliminating smells from a toilet subject hereof can be seen to be constructed with a housing (1) for an electric motor fan, of suitable power, in which the motor as such is arranged facing down, whereas the other part (2) of the housing has a fan (3) located at the top, which housing part (2) has an axial inlet facing vertically down, and a tangential outlet (4) which, in the practical embodiment shown in the figures, is quadrangular in section and has a grid (5) at the outlet mouth (4).
  • This outlet (4) can clearly have any other suitable geometric shape.
  • the housing of the unit, and in particular part (2) where the fan (3) is housed, has a bracket (6) with which the unit may be fixed to a support (7) which may be fixed on the wall, on the floor or indeed have suitable means allowing the unit to the mounted and fixed on the top of the toilet (8), in particular with the bolts fixing the ring (9) to the toilet.
  • the support (7) will at all events carry a pair of holes (10) facing the holes with which the bracket (6) is provided to such end for the fixing bolts to be inserted, as is clearly illustrated in the figures, thereby for the device as a whole to be perfectly mounted on the support (7) and the support fixed on the floor.
  • a transformer (11) is in turn fixed to this support (7) supplying the actual motor fan lying within housing part (1), which transformer (11) is in turn supplied directly from the mains, through the relevant lead (12).
  • the motor fan is switched on and off manually by means of a duly positioned switch (13).
  • the inlet to housing part (1) for the motor fan is fitted with a bushing (14) that is cylindrical in shape and has a flange (15) for adjustment to the housing (1) of the motor fan (3), such being fixed by welding or else forming a single element, in which case holes (18) will be provided facing other holes (18) of the general housing, for both parts to be bolted to each other.
  • Said bushing (14) receives an aspirating nozzle (19) telescopically, the position of the nozzle with respect to the bushing (14) being adjustable in height with the assistance of an o-ring seal (25), the aspirating nozzle (19) being provided with a flat radial extension (21), defining a mouth (22) of considerable width and little height, said extension (21) being couplable to the toilet (8) between the mouth of the toilet and the annular seat (9) when such seat or ring (9) is in the operative position.
  • An activated carbon filter (20), lying between two grids (17), has also been provided to be mounted above the fan (3), and specifically in the cylindrical bushing (14).
  • the underside of the ring seat (9) has been provided with a seal (23), defining a perimetric seal between such ring seat (9) and the mouth of the toilet (8), such seal (23) being discontinued precisely in a small sector (24) where the flat extension (21) of the aspirating nozzle (19) is coupled.
  • the device offers a number of details as concerns different functions within the same concept, and thus in figures 4 to 7 the same numbers have been used for the common parts of the device, albeit followed by an apostrophe.
  • figure 4 shows the device in this second embodiment applied to a toilet (8') with its respective ring (9'), the housing of which device is formed by coupling together two parts, a bottom part identified as (1') and a top part identified as (2'), the latter housing the relevant fan (3') and extending at the top into a bushing (14') to receive an aspirating nozzle (19') telescopically, the position of such nozzle with respect to such bushing (14') being adjustable in height with the assistance of the o-ring seal (25'), which aspirating nozzle (19') has a flat radial extension (21') that lies above the top edge of the toilet (8'), below the ring or annular seat (9') of the toilet.
  • the neck (14') of the top part (2') of the general housing of the device includes the relevant activated carbon filter (20'), the above as in the embodiment described and shown in figures 1 to 3.
  • the bottom part (1') of the housing, where the relevant motor (27') is housed is provided with a bottom extension (26') which houses the relevant transformer (11'), this part (26') housing the transformer (11') being polygonal whereas the area (1') where the motor (27') is housed is cylindrical and has a larger contour.
  • the transformer (11') will supply the motor (27') through the relevant lead (12') and will have an on/off switch (13').
  • the outlet mouth (4') through which purified air leaves propelled by the motor (3'), has dividers (28'), out of phase with each other, to define a labyrinthine conduit and prevent the inflow of objects and indeed dirt which might damage or be prejudicial to the fan (3') as such.
  • the transformer (11') is separated from the bottom of the housing part (26') by means of dividers (29') lying on such bottom, and constituting a support for the transformer (11') proper, moreover enabling the transformer to be ventilated, cooling thereof being consequently enhanced.
