Abstract

A device for flushing, cleaning and servicing sanitary fixtures including an apparatus (1) capable of heating and draining under control a pressurized fluid containing deterging, disinfecting, deodorizing substances and agents for dissolving calcareous deposits mixed with a suitable fluid which is conveyed to the sanitary fixture (4) through pipes (3) ending in spray nozzles (41) which are placed around the upper edge of the sanitary fixture (4) so as to direct the flush of the cleansing fluid to the inner surface thereof.

Description

FLUSHING. CLEANING DEVICE FOR SERVICING SANITARY FIXTURES

The present invention relates to the field of the devices for flushing and cleaning sanitary fixtures, particularly the toilet bowl.

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 quan¬ tity of specific products to be used. In addition, it should also be appreciated that water shortage in particu¬ lar environments or areas makes it necessary to wisely use the available resources. It is enough to think to the lit- tie 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 hy¬ giene 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. 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 cal¬ careous deposits in the pipes as well as cleansing agents and disinfectants along with their application means.

The present invention seeks to overcome such problems by providing a device of easy use and little overall dimen¬ sions which can be installed both in old and new facili¬ ties 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.

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 drasti¬ cally 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, ap¬ propriate rat disinfestation substances may be periodi¬ cally 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 fa¬ cilities as it may be connected to the water pipe network or to a flush tank and be positioned above or below, out- side 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 en¬ vironmental pollution available on the market.

These and further advantages will be better intended by anyone skilled in the art from the following description with reference to the annexed drawing given as not limiting example and in which:

Fig. 1 shows schematically a preferred embodiment of a de¬ vice for cleaning sanitary fixtures according to the in¬ vention.

In a preferred embodiment of the invention the construc¬ tion of a device for flushing and cleaning domestic sani¬ tary fixtures can be combined with the waterworks and the electric system generally existing in the buildings. More particularly, with reference to Fig. 1, such a conceived device consists of a water flush box 1 which is provided with an electromotor and heating elements, housed in the wall 5, connected to water inlet pipe 2, and supplied by wires 6 connected to the electric system. The front side of the water flush box 1 is provided with a control panel 7 including: a door 71 of an inner tank 75 containing the substances to be added to the water; a pilot light 72; an operation push button 73; a setting thermostat 74; an air intake 76 for the electromotor.

Provided at the output of the water flush box 1 is a con¬ duit 3 which is connected at the other end to the gasket type union of a toilet bowl 4 connected in turn to nozzles 41 placed around the whole upper edge of the bowl 4 and directed to the inner surface thereof.

In operation, the water flush box receives water from pipe 2 and heats it by means of electric resistances controlled by thermostat 74. At the same time, the desired cleansing fluid is obtained by taking from tank 75 the deodorizing, deterging, disinfecting substances and the agent for dis¬ solving the calcareous deposits. In use, the user pushes the operation button 73 and holds it until the desired degree of cleanliness is reached. Advantageously, only a few seconds are needed to reach the cleanliness of the bowl because of the simultaneous action of detergents, heat, and intensity of flushing. Further, the design of the inner walls of the bowl 4 and the arrangement of the nozzles 41 are combined so as to direct the flush without dispersions, thus optimizing the cleansing efficiency. Advantageously, as a comparison with the water flushes of the market and their necessary adaptations, the device ac¬ cording to the invention may be installed in a very re- stricted room of the order of a couple of 20x20 cm tiles, and may request a maximum electrical input of about 2 kW which involves a negligible consumption due to the limited operation time.

The detail of the preferred embodiment may be varied in the form, dimension, nature and arrangement of the compo¬ nents without parting from the scope of the inventive spirit and then remaining within the limits of protection of the present industrial invention.
