ABSTRACT:
TECHNICAL FIELD OF THE INVENTION
This invention relates to a sanitary device for the stools of household animals, of the type which comprises a bowl provided with a defecation bed made up of a granular material on which the animal defecates, water irrigation means, disincrustant and/or disinfectant to dilute and wash away the stools and for cleaning the device, the bowl being provided at its essentially lower part with emptying means which can be attached to the pipes of a drain installation.
The device of this invention finds particular application in private dwelling houses or in communal areas.
BACKGROUND OF THE INVENTION
Known at present are a wide range of devices for disposing of the stools of household animals, which devices can be installed in the actual house of the owner of the animal or in a private communal area.
Amongst other types, known in the art are devices which comprise a bowl provided with a defecation bed of gravel on which the animal defecates, such as that described in EP-A-0277863.
Also known in the art is the use of means of water irrigation, descaling agent and disinfectant for dilution and washing away of the stools in order to clean the device following use thereof by the animal, and the aforesaid defecation bed being provided with emptying means that can be attached to the pipes of a waste water disposal sewage installation, such as a domestic wastewater installation. Patents WO 97/10705 and ES-A-2034863 make known devices of those characteristics.
Although in practice such devices work correctly, they have the initial disadvantage that their make-up and installation are generally complex, since they must normally be fixed unmovably in one permanent location.
Furthermore, cleaning of the device itself calls for recourse to a manual action of cleaning “in situ”, involving necessarily a certain degree of physical contact of the hands with the dirty parts of the device, which involves a second disadvantage, since it is unpleasant and can be a health hazard. The alternative of removing the device to take it to a place where washing is more convenient and without threat to health, for example to an open area, is inconvenient and amounts to another disadvantage.
DESCRIPTION OF THE INVENTION
The object of this invention is a new embodiment of a sanitary device for the defecation of household animals, providing a solution to all the disadvantages described above and benefiting from improved hygiene and convenience.
The device of this invention is essentially characterised in that it is provided with
a grill, mounted under the defecation bowl and provided with a sieve designed to allow the dissolved stools to pass but not the material from the bed;
a lift-up cover made up of a hollow body whose lower part is provided with holes for distributing water, disincrustant and/or disinfectant, articulated onto said bowl;
means for feeding warm or cold air to said lift-up cover for drying the interior of the device after it has been washed; and
means for dispensing the descaling and/or disinfectant product,
all this so arranged that the lift-up cover is designed to take up a lowered cleaning position, covering the bowl, in which the water irrigation and/or drying means for the device can be activated, and a raised operational position, in which said irrigation means are deactivated and in which the animal can defecate, it being possible to fit the device movably in a dwelling or in a communal area.
According to another characteristic of the invention, the device includes valve means for feed to the irrigation means, designed to cut off that feed when the lift-up cover is in its raised position.
In an alternative form of embodiment of the invention, the device can be adapted to a conventional sink, the irrigation means then being formed by the tap of the sink itself, and the products carried away during washing being poured in the sink drain.
According to another form of embodiment, the lift-up cover is driven electrically.
