ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to the field of the devices for flushing and cleaning sanitary fixtures, particularly the toilet bowl.
BACKGROUND OF THE INVENTION
As well-known to everybody a lot of different products or accessories such as brushes, sponges, sprayers and the like are employed at the present state of art for cleaning sanitary fixtures, Such a lot of accessories make the cleaning of the sanitary facilities particularly lengthy, tiresome and expensive because of the cost and the quantity of specific products to be used. In addition, it should also be appreciated that water shortage in particular environments or areas makes it necessary to wisely use the available resources. It is enough to think to the little water available in boats and trailers for holidays or, more seriously, in some geographic areas where water shortage is one of the most severe problems.
A further serious drawback directly influencing the hygiene of people is the difficulty and the insufficiency of some public bodies such as schools, colleges, camping, hospitals, where the sanitary facilities are often in a critical situation due to the high number of users, thus causing a risk for the health of the people.
DE-A-2826094 discloses an apparatus with a separated conduit for the cleaning fluid, suitable to be operated after the flushing operation.
FR-A-2603054 discloses an apparatus for the cleaning of the toilet bowl seat suitable to be fitted to all types of toilet bowls.
These solutions only partially solve the problems of the cleaning of the toilet bowls, and show a plurality of technical difficulties related to the installation of the additional devices that are not fully integrated with the toilet bowls' structure.
To solve such problems, in the hitherto installed sanitary facilities, particularly the toilet bowl, an additional supply of water is drained together with deodorizing soap, whereupon further cleaning and servicing interventions are needed such as the use of products for dissolving calcareous deposits in the pipes as well as cleansing agents and disinfectants along with their application means.
SUMMARY OF THE INVENTION
The present invention seeks to overcome such problems by providing a device which is easy to use and has little overall dimensions, which can be installed both in old and new facilities in order to allow the sanitary fixtures to be cleaned and deodorized in a little time with low consumption of water and cleansing agents and, at the same time, also operates as descaling and disinfectant agent for pipes.
The present invention is based on the inventive concept of providing a new electric appliance capable of doing without the usual flush tank and the auxiliary cleaning means such as the long-handled scrubbing brush as it is provided with means for heating and pressurizing water from a domestic water supply and for mixing the water flush under pressure with cleansing agents.
To this end, a device for cleaning and servicing sanitary fixtures according to the invention includes means for heating and draining under control into the sanitary fixture to be cleaned a pressurized flush of detergents, disinfectants, agents for dissolving calcareous deposits mixed with a suitable fluid which is supplied through pipes ending in spray nozzles placed along the edge of the sanitary fixture so as to flush the inner surface thereof until the draining pipe.
The advantages essentially consist in that such a device can allow the flow rate of the cleansing fluid to be varied according to the amount necessary to clean the sanitary fixture, thus saving water and cleansing agents. Moreover, the hitherto requested interventions to clean, deodorize and disinfect the sanitary fixtures and to prevent scales from being formed in the pipes are drastically curtailed. It should be further appreciated that such features are particularly important in the already mentioned public installation where the general use of the present invention easily and effectively solves the problem of the hygiene both of the sanitary facilities and the connected sewer line in which, if it is the case, appropriate rat disinfestation substances may be periodically poured.
Further advantages of the invention are the versatility and easiness of use, the noiselessness of operation, and the capability of being installed both in old and new facilities as it may be connected to the water pipe network or to a flush tank and be positioned above or below, outside or inside the masonry.
Finally, the device of the invention allows the desired admixture of the substances to be added to the main fluid and the suitable selection of those having the lowest environmental pollution available on the market.
