Massenberg Attorney-Wenderoth, Lind and Ponack ABSTRACT: A toilet fitting comprising a hollow seat adapted to be mounted on a toilet bowl and containing suction orifices through which air is drawn off into a suction chamber and thence to atmosphere or to an outlet pipe by an air extractor. To simplify servicing and to reduce noise the air extractor comprising a fan, an electric motor and the necessary switchgear is mounted in a replaceable cartridgelike device which is housed in a hollow extension of the seat.
PATENTEDAUGI 1m:
HANS MIUSCH Attorneys TOILET FITTING The invention relates to a toilet fitting comprising a hollow seat element adapted to be mounted on the edge of a toilet bowl, which element contains suction orifices which through the interior of the seat element communicate with a suction chamber from which air is drawn off by an air extractor accommodated in a hollow extension of the seat element, the extracted air being delivered to atmosphere or to an outlet pipe.
Toilet seats of this kind have proved efficient in practice; difficulties arise however if parts of the air-extractor, i.e. the fan, the electric motor or the switching elements have to be replaced as a result of their being damaged. Also, in some instances, the noise from the extractor is troublesome.
The object of the invention is to provide an improved toilet fitting in which the air extractor, together with the associated parts, can be readily replaced in the event of their being damaged, and which also enables noise to be reduced in an effective manner.
According to the present invention, the air extractor together with the associated parts is accommodated in a cartridgelike replaceable device which can be inserted endwise into the hollow extension, the device being provided with a projecting switch actuating element. In this way there is provided a replaceable device which can be readily changed at any time as a whole. This provides the advantage that the toilet seat can still be used, without ventilation, when replacement of the device becomes necessary. Since the air extractor is not rigidly connected with the toilet seat, noise can be reduced in a particularly effective manner, preferably by means of a resilient, noise-reducing mounting of the cartridgelike device in the hollow extension. The hollow extension is expediently swingable with the toilet seat, the mounting beingachieved by means of a bowed hinge firmly connected to the toilet bowl.
' In a preferred form of construction, the cartridgelike device comprises a first and second tubular part of equal external diameter joined by an intermediate part which is of lesser ex ternal diameter and is formed with suction orifices in its wall, the first tubular part accommodating a fan and an electric motor and communicating with the interior of the intermediate part through a bore shaped in the manner of a nozzle, and the second tubular part accommodatingswitch elements for controlling the motor. This tubular cartridge can be inserted in the, various retaining means without the need for its being aligned in any particular position, and provides a very good suction action in the constructed intermediate portion which communicates with a suction chamber contained in the hollow extension. The filter element, which is expediently likewise designed to be replaceable, can be combined with the cartridgelike device or can be fitted separately from this device in a holding means associated with the hollow extension.
In order to achieve reduction in the transmission of noise beyond that already achieved by the resilient, noise-reducing mounting of the cartridgelike device in the hollow extension, it may possibly be expedient to provide the surface of the inner wall of the device, at least near the fan, with a noise-inhibiting coating. This can preferably be constituted by a smooth, relatively solid top layer and, below that, a porous, resilient under-layer, or, in simple cases, the coating can be a rubbery lacquer.
It would also appear to be advantageous for the upper surface of the toilet seat to be raised and to be of circular cross section where it is contiguous with the outside diameter of the hollow extension. This results in a sitting surface suiting anatomical requirements and a smooth transition towards the hollow extension; which facilitates cleaning since no edges and corners are present.
The cartridgelike device can be made of metal or plastics material. The fan and electric drive motor are likewise preferably mounted in a resilient manner so that the transmission of sound vibrations is reduced at this point. The out- .wardly projecting part for actuating the switch expediently takes the form of a button having a pressure surface of adequate size.
The use of the above-described features results in a ventilated toilet seat, the air extractor of which, including the associated switch elements, can be readily replaced, and in which moreover effective inhibition of noise and a configuration suited to anatomical requirements can be achieved. The toilet seat is of good overall appearance and can be easily cleaned since it has no comers in which dirt can collect.
An embodiment of the invention is illustrated schematically in the accompanying drawing, in which:
FIG. 1 is a side view, partly in section, of the toilet seat of the invention,
FIG; 2 is a plan view ofthe toilet seat seen in FIG. 1 ,and
FIG. 3 is a side elevation of a cartridgelike insertable part.
Referring to the-drawing, a hollow toilet seat 2 is shown mounted on a toilet bowl 1. A hollow attachment or extension 3 may be connected to or, if required, made integral with the seat 2 and both parts are mounted to be swung together on a pivot secured on the toilet bowl 1. A cover 4 is also mounted to be swung about the same pivot.
As can be seen from FIG. 2, the hollow attachment 3 accommodates a resilient, noisereducing and inhibiting annular mounting 5. Air is drawn through orifices 6 on the underside of the seat 2 and through a suction chamber 9 by a fan driven by an electric motor 8 and is exhausted through a filter element 10 which is likewise replaceable and is inserted in the hollow attachment 3.
The cartridgelike insertable part consists of a first tubular portion 11 in which the fan 7 and the electric motor 8 are accommodated. Connected by way of a suction bore 12, reduced in the manner of a nozzle, is an intermediate portion 13 of smaller diameter which contains suction orifices 14 on its circumference. There then follows a second tubular portion 15, the diameter of which corresponds to that of the first tubular portion 11 and in which are accommodated electric switching elements 16, a projecting actuating member 17 being provided. The inner surface of the wall of the first tubu lar portion 11 is provided with a noise-inhibiting coating 18. Within the first tubular portion 11, the fan 7 is mounted, by way of the electric motor 8, on a retaining means, not shown in the drawing, which is disposed concentrically with the longitudinal axis of the tubular portion.
As already mentioned, the hollow attachment 3 and the toilet seat 2 are solidly connected and, together with the cover 4, can be swung about a common pivotal point fixed by a bowed hinge 19. The bowed hinge 19 is firmly connected to the toilet bowl 1 at the rear edge portion thereof.
