The invention relates to an automatic flush apparatus for urinals that operates by automatically sending water from the water supply network, which contains chemicals, to the urinal. The inventive apparatus is completely different to those currently available owing to the novel internal construction thereof. Said construction is essentially characterised in that it combines the advantages of existing devices with the added advantage of flushing with water that contains chemical products which clean, disinfect and perfume the urinal.

Description

"Automatic Unloading Apparatus for Urinal, with Chemical Deposit."

Background of the Invention

Currently, conventional urinals use a water discharge for cleaning, which is provided by conventional systems. This discharge is conventionally controlled manually by means of a stopcock, or by means of a flushometer, which can either be manual or automatic. As it may well be thought in the first case, the waste of water is abundant if the stopcock is normally open and in the case of flushometers, these are designed for the requirements of a 3-liter discharge. These two ways of cleaning a Urinal apparatus, are not necessarily the most appropriate since they involve a large waste of vital liquid on the one hand and high costs for maintenance and facilities on the other.

Another problem that involves the use of a stopcock or a manual flushometer, is that when a user uses the urinal device, he does not operate it manually, either for hygiene or because he is not interested in operating them, which causes serious problems hygienic and odorous.

With the purpose of suppressing these and other drawbacks, the development of this Automatic Urinal Discharge Apparatus, with a Chemical Deposit, was considered, which is intended to protect by means of this application, since it is a device made up of elements that they work more efficiently than those commonly found on the market.

With reference to these figures, the apparatus is made up of a casing with two sections (10 and 40) joined by a pair of hinges (401), swinging open forwards in order to be able to install the internal mechanisms or to maintain them once these have been installed, as illustrated in fig. 4; the front section (10) of the casing is fixed to the rear section (40) by means of screws (31) as illustrated in fig. 5.

The construction of the Automatic Unloading Apparatus for Urinal, with a Chemical Tank is shown in Figures 4 and 6, and the arrangement of the parts can be observed. In the rear section of the casing (40) a seat (403) can be seen in the center, where the low energy consumption solenoid valve (41) is placed.

The solenoid valve (41) incorporates a coil (410) connected by means of a cable (411) and a male coaxial connector (412) to the female coaxial connector (471), which in turn is connected by means of cables (470). with an electronic card (461), likewise said solenoid valve (41) it incorporates a water inlet connector (413) and a water outlet mixer connector (42) through said mixer connector, water is poured into the urinal in mixture with the flavoring and disinfectant (432) coming from the tank (43).

The solenoid valve (41) incorporates a connector (413) which in turn incorporates a nipple (17) and a connection nut (16) through which water enters for discharge; the water enters through said connection nut (16) and passes through the nipple (17) to the connector (413) and from there to the solenoid valve (41), said water passes to the mixer connector (42) through the conduit (424) passing Much of this water through a discharge conduit (429) to the discharge tube (14) mixing with the water that comes from the tank (43) of the disinfecting and flavoring chemical (432) and that comes through the conduit (430). Said solenoid valve incorporates a mixer connector (42) which in turn has an inlet conduit

(424) of the water coming from the solenoid (41), a small percentage of the water is led through a duct (425) and a connector (426) to a duct (441) that leads the water to the tank (43) of the disinfectant and flavoring chemical (432); the flow coming from the solenoid valve is controlled by means of a regulating valve (44) by means of a handle (442) so that the flow of the water reaching the tank (43) can be controlled, said regulating valve (44) is incorporated in the lid (431) of the tank (43) of disinfecting and flavoring chemical (432), the water once inside said tank (43) is impregnated with the disinfecting and flavoring chemical

(432) which comes out through the outlet hole (433) made in the tank (43) through a conduit (434) and passes to an elbow (421) through its conduit (427), continuing through a conduit (430) of the hose (423) and joining to the rest of the water inside a discharge tube (14).

The front section of the casing (10) incorporates a sensor module (11) composed of an electronic sensor card (112) that together with LEDs (12) allow the presence of the user to be detected and according to the range established in a potentiometer (21) placed in the hole (210) of the casing (40) to which it is fastened by means of a nut (213), said potentiometer is connected to an electronic card (461) by means of a cable (211) that it incorporates a male connector (212) to a connector (465) that is connected by means of cables (472) to the electronic card

(461); said leds (12) are mounted on a led holder (11) which in turn is fastened with a nut (115) to the housing

(10). The sensor module (11) connects to a female connection (464), which in turn receives a connector (463) from the electronic card (461), allowing when the sensor module (11) detects the presence of a User sent a signal to the electronic card (461), which processes said signal and sends an opening signal to the solenoid valve (41), which is connected through a female coaxial connector (471), which receives a male coaxial connector (412). ) of the solenoid valve (41).

This apparatus incorporates a manual action button (20) for discharges caused for the purpose of diagnosing the equipment or for any other purpose; said button (20) is placed in the hole (402) of the casing (40) and fastened to it through the nut (203), said button (20) is connected through its cable (201) and its male connector (202) to a female connector (467) that is attached to the electronic card (461) through cables (466). For the preferred embodiment of this invention, a battery module (45) is incorporated that provides the electrical energy for the operation of the apparatus, through a cable (451) and a male connector (452) connected to a female connector (469). ) and to the electronic card (461) through the cables

(468); the operation of said apparatus can also be by means of alternating current.

The efficiency in the work of this Automatic Discharge Apparatus for Urinal, with a Chemical Tank resides in the fact that, as already stated, the water coming from the network enters through the planned connections, passing to the solenoid valve, which is the one that performs the operation of discharge, having as a fundamental basis a mixer connector that sends water in small quantities to a tank containing chemical material for cleaning, hygiene and flavoring of the urinal cabinet, where the water from said tank impregnated with the chemical returns to the mixer connector and joins with the rest of the water flow, providing a totally different discharge from what is currently known.

The design and discharge method of this device is part of its novelty: the mixer connector serves to divert a small amount of water to the chemical tank, the mixer connector sends more water directly to the discharge, joining these two flows into one in the discharge tube.

Another of the novel elements of this apparatus and that complements its operating conditions, is the sensor module connected to an electronic card that in turn sends a signal to the solenoid valve when the apparatus is used and the user leaves the area of coverage of sensor, initiating the process of discharge of water impregnated with chemicals.

These conditions allow the use in this Automatic Discharge Apparatus for Urinal, with Chemical Tank, a solenoid valve that opens and closes the flow of water, in collaboration with a mixer connector and that these elements as a whole allow us to have a discharge of water to a urinal cabinet, automatically and at the same time with water impregnated with chemical materials that provide cleaning, hygiene and flavoring to the urinal cabinet.

In this way, an Automatic Discharge Apparatus for Urinal is obtained, with a Chemical Deposit, whose operating characteristics are as follows:

A) When poor quality water enters the appliance, some sieves placed in the connection nut prevent the passage of garbage or foreign objects to the solenoid valve, thus keeping it in optimal operating conditions.

B) When the water has passed through the solenoid valve, it is distributed by a mixer connector to the chemical tank, subsequently joining with the discharge flow.

C) When more water enters the chemical tank, it can be controlled by means of a regulating valve.

D) When this appliance performs a discharge cycle, the average cost is from 1 to 1.5 liters. per discharge, without impairing the efficiency in it. E) When this appliance discharges into the urinal cabinet, it cleans, sanitizes and aromatizes it by performing a discharge of water impregnated with a disinfecting and flavoring chemical, providing pigmented water that provides a totally different appearance and resulting in a clean urinal cabinet. , disinfected, flavored and with foam.

F) When this apparatus performs its operation, it is completely electronic, since both opening and closing are carried out completely electronically, since the solenoid valve responds to electrical impulses to open the flow of water and to close the flow.

For all the aforementioned, it can be affirmed that these characteristics in an Automatic Discharge Apparatus for Urinal, with a Chemical Tank have not been achieved by any other similar device and it meets in itself the characteristics of an automatic discharge of water impregnated with disinfecting chemical. , flavoring and coloring.

Other complementary characteristics of this apparatus is that the chemical tank always maintains a water level so there is always water impregnated with the chemical, therefore the chemist carries out his work with each discharge of the apparatus from the beginning of its cycle of operation.
