Description

The present invention relates to a vending machine with an adjustable volume dosing pump which is mounted in the toilet tank to automatically dispense, with each use of the toilet and at the end of the emptying cycle, a pre-diluted, adjusted and adapted dose of sanitary product. to the volume of water to clean, disinfect and deodorize the toilet bowl.

The cleaning and disinfection of private and collective toilet bowls in companies, restaurants, hotels, holiday centers and resorts, public establishments, hospitals and clinics, medico-social establishments, regularly requires the manual intervention of the personnel in charge of operations. maintenance, the frequency of intervention depends on the use: domestic private, collective, intensive. These interventions are tedious and unpleasant and collective places are often poorly scented with bowls insufficiently cleaned and especially with a questionable disinfection, sometimes even nonexistent. Often there is a strong smell of deodorant with a bad smell of dirty toilets.

The use of perforated plastic support is commonly used, hooked to the inner rim of the bowl with a pellet containing anti-scale products, anti-odor, which dissolves the repeated passage of water, in order to clean the bathroom.

The disadvantages are major, on the one hand these pellets dissolve very quickly as soon as they have been in contact with water, on the other hand the flow of the rejected water leads directly, in its wake and laterally to d evacuation in a few seconds the product of the dissolution obtained in the sewers. Towards half of its use the pellet dissolves suddenly and completely creating a high concentration of product that goes completely to the sewers, during evacuations of water, there is very little product at the bottom, it never reaches or covers all the inner surface of the bowl thus making the desired action very insufficient and inefficient and especially without having antibacterial action which is one of the basic rules in terms of cleanliness and hygiene. We know that the toilet are a place of microbial proliferation. The tests carried out show that with an open toilet seat, projections are collected at a distance of one meter containing substances with harmful germs.

When with an involuntary gesture the plastic support is unhooked and slips into the bottom of the bowl, its recovery becomes delicate, because even if the product of the pellet is finished, it is still necessary to remove the plastic support.

There are also single-use effervescent tablets that are deposited in the siphon of the bowl, in order to descale and remove stains, these products act only in the bottom of the siphon and on the sewer drain pipes. . It is necessary to wait for the dissolution and the action of the pellet before being able to reuse the toilets which evacuate the product to the sewers.

A device similar to the previous one is also proposed, it is a plastic support on which is placed a small bottle of liquid sanitary product, mounted hanging inverted on the inner edge of the bowl, the product is supposed to slowly pour in the passage water, it is quite otherwise, the bottle empties very quickly and especially without reaching and coat all the interior surfaces of the toilet bowl, emptying flush systematically evacuates in its wake and laterally in a few seconds almost all the products in the sewers, it remains nevertheless a very small part of product and its action is limited in the siphon of the bowl.

Another system proposes to connect the toilet seat to the extraction of air from the centralized mechanical ventilation to suck the unpleasant odors, which does not solve the need for cleanliness and deodorize really the points of production of odors as well than the inevitable imperative of disinfection.

Also there is a device called diffuser placed in the toilet tank equipped with a fixed capacity doser moved by a float and adapted to the only product of the mark, the dilution of the cleaning product is done in the totality of the water the toilet tank, this extremely low dilution of approximately 1/5000 ^th and more, lets presuppose the use of a highly concentrated product, the dosage is about two milliliters to eight liters of water on average in a toilet tank.

The major disadvantage is that the water of the toilet tank with its small amount of product is completely discharged to the sewers by the action of flush toilet, A water evacuation that takes place between 3 to 5 seconds does not can produce effects other than that of the passage of water, therefore there is actually and virtually no final product too little in the toilet bowl to be able to act in terms of cleaning or effective disinfection. This system allows the low dosing solution to leach all surfaces and the entire product is evacuated in 4 seconds directly to the sewers.

In all the above cases, this amounts to evacuating 90% of the products used in the sewers and with one-tenth of water and product remaining, too diluted dose and not adapted to the remaining volume of water, to try to clean, to disinfect and deodorize the toilet bowl.

Another system proposes from a thick and sticky gel, manually compressed and pushed by a piston in its cylindrical support, this system makes it possible to deposit and stick a pellet of this sticky gel on the inner wall of the toilet bowl, for disinfect and deodorize. This system is one of the last product currently marketed, the deodorant effect does not last as much as the presence of the pellet, as for disinfection, the product is subject to the direct passage and laterally water and can not in any case achieve and cover the inner surfaces of the bowl. As for the cases mentioned above, everything is evacuated to the sewers.

Other multifunction products in liquid form, powders, are marketed, their jobs always require the regular intervention of the staff responsible for cleanliness, so very often there is a slogan posted, "Thank you for leaving this place as clean as you found it by entering ", or humorous posters that say a lot about cleanliness and smells, and, at best, make available a deodorizing bomb that does not disinfect anything and that we know that the vaporization of micro particles are dangerous for health.

Professionals are not mistaken, during inspection visit, toilets are the first point of visit. A practice in the restaurant, a preliminary visit of the toilets provided us with elements of appreciation.

The present invention, the automatic dispenser dosing pump with adjustable volume, aims to meet and satisfy the need of the technical problem: clean, disinfect and deodorize regularly and effectively and permanently all the inner parts of the toilet composed: from from the inside of the water tank, the filling and evacuation mechanisms, the internal ducts of the water passage circuit and especially of all the internal surfaces of the bowl, even surfaces inaccessible manually.

The adjustable volume dosing pump of the dispenser makes it possible to regulate the volume of the dose of liquid product with respect to a determined volume of water, and, to maintain this dosage adjusted throughout the use of the same product, to clean , disinfect and deodorize the toilets. The user can vary the volume of the dose according to the need and the product, with the possibility of using commonly marketed products. Each product having its protocol and specifications of dosages.

The automatic dispenser dosing pump with variable volume can be equipped with two versions of variable volume dosing pump: figures 1 and 3 , represent the diaphragm pump dosing version (4c), the figures 2 , 4 and 5 , represent the piston pump metering version (6a).

For both versions of adjustable volume dosing pump, figures 1 and 2 , the operation is the same, the operating cycle is broken down into four phases with respect to the emptying and filling of the toilet tank (2). With reference to the figure 1 ,

First Phase: From the emptying and evacuation of water from the toilet tank (2), the dispenser allows 90% of the water to flow out of the toilet tank, to evacuate after use the contents of the toilet bowl with a classic cleaning with fast water flow. During this emptying the water level drops and the float (10) descends and drives the membrane (4c) which allows the sanitary product contained in the tank (1) to be sucked in and to be introduced by the valve entering (7) in the volume above the membrane (4c) of the metering pump (4), which represents a first technical feature.

Second Phase: Before the end of the emptying, while it remains being evacuated in the toilet tank (2) only 1.5 liters of water, the float (20), fixed to the articulated lever (19) , flip-flop and instantly triggers the opening of the valve (17) of the auxiliary tank (15) which releases the pre-dilution immediately mixed with the end of the water flow of the toilet tank (2), the set and pre-diluted dose of sanitary product is prepared by the previous cycle in the annex tank (15).

It takes 1.5 liters of water or 4.5 centimeters of water in the toilet tank (2) and this is the precise moment of the triggering of the opening of the valve (17) to constitute, with the pre-dilution of product, the right amount of adequate mixing corresponding to the specification of the sanitary product, to sanitize and deodorize the toilet bowl, which is a second technical feature.

Another peculiarity is that the totality of this mixture, consisting of this 1.5 liter of water and the pre-dilution of product, from the toilet tank (2) allows an optimal action of the product is the maximum volume of water with the product dose recommended by the manufacturer, calculated so that this final volume corresponds to the volume of the siphon and is not discharged to the sewer, so the mixture is collected in the siphon of the bowl in which it remains until 'the next use of the toilet. From the toilet tank to the siphon of the bowl the mixture has covered and coated all of the sensitive interior surfaces of the toilets on which the product adheres, even surfaces inaccessible manually, which represents a third technical characteristic.

Third Phase: The third phase corresponds to the water filling of the toilet tank (2), the rise of the water immerses the float (20) which by its action on the articulated lever (19) closes the check valve ( 17) of the auxiliary tank (15).

Fourth Phase; The filling of the toilet tank (2) continues, the level of the water rises and immerses the float (10) and its vertical thrust exerted on the pusher (4d) and on the membrane (4c) causes the discharge of the sanitary product , charged in first phase and contained above the membrane (4c), through the outlet valve at (8) of its sealed duct (8a) and is discharged by the pouring spout (8b) from above into the auxiliary tank (15), the rise of the float (10), of the pusher piston (4d) and the diaphragm (4c) stops when the plate (4e) for fixing the diaphragm (4c) comes into contact with the stop adjustment rod (5) and determines the set point of the volume of the dose, which represents a fourth technical characteristic.

The full tank of the toilet (2) is reached, the water fills the auxiliary tank (15) by the filling slot over the adjustment slide (21) and prepares, for the following cycle, the pre-dilution with the dose of sanitary product received from the dosing pump (4). which represents a fifth technical characteristic.

In this auxiliary tank (15) is prepared with the dose of product that has just been transferred and the water contained in this tank pre-dilution, which facilitates better and faster to mix with the end of evacuation of the next use a toilet, which represents a sixth technical characteristic.

the use of the automatic dispenser allows the sanitary products to act in the best of their effectiveness to reach the objective of a real cleaning, a disinfection, an anti-scale treatment of all the internal surfaces of the toilets and to deodorize this set and the local as it is done during a manual intervention.

After the treatment preparation, when emptying the reservoir (2), covers and coats all the sensitive interior surfaces of the toilet, this final volume of treatment preparation is not discharged to the sewer and holds it in the siphon of the toilet. toilet bowl makes it easier and efficient, when needed, the use of the brush, or brush, toilet without necessarily resorting to another flush toilet, or seek additional cleaning product.

The current liquid products on the market offer multifunctional treatments that are perfectly adapted and usable by the automatic dispenser dosing pump with adjustable volume.

With reference to these drawings, the automatic dispenser dosing pump with adjustable volume, figure 2 , consists of the main tank (1) to receive and contain, the various sanitary products used to sanitize the toilet, and the annex tank (15) open with filling slot.

The auxiliary tank (15) is attached laterally to the main tank (1), these two tanks may optionally be made in one piece. The auxiliary tank (15) can also be mounted vertically adjustable sliding against the reservoir (1) with a holding screw in position for the setting point of the triggering of the opening of the discharge valve (17) by the float (20). ) when there is only 1.5 liters of water remaining at the end of the evacuation.

These two tanks are mounted inside the toilet water tank (2) from the existing and free reservation hole, the toilet water tanks are marketed with two holes for the left or right attachment of the water tap. arrival of water. It is also possible for toilet tanks with water inlet from below or different to provide fixing systems, by jamming or tight side hooks to the edges of the tank (2).

A sealed assembly of the main tank (1), figure 6 , with the toilet tank (2) is made from the neck (3) for filling products of the tank (1), made by screwing two nuts (3a) on the neck (3) outside the tank ( 2) and inside the tank (1), enclosing two seals (3c). The neck has a flexible lid (3b) for closing and protection. The neck can be transparent, to visualize the full level.

The main reservoir (1) has a rigid lid (13) on which is indicated the adjustment of the volume of doses from the indexed knob (14) actuating the volume adjustment rod (5).

In the bottom of this main tank (1) is a vertical cylindrical recess in which the adjustable volume piston pump device (6) is mounted, the assembly is carried out from below by four-point pickings, detail A on the figure 4 represented in figure 9 , or by screwing, not shown, from the base of the metering pump (6) to the reservoir (1). A circular seal (11) seals with the sanitary treatment product present in its upper part and the water of the toilet tank in which this assembly of the dosing pump is immersed.

This assembly allows a tight assembly for the maintenance of the pump dispenser in place.

The stop adjustment rod (5) of the volume is aimed at the top and at the center of the pump dispenser (6) in a centered and threaded hole, the screwing or unscrewing of the adjusting rod (5) constitutes the adjustment stop of the volume of the product dose, the stop position of the adjustment rod (5) thus obtained determines the adjustable high point of contact of the upper part of the piston (6a), which limits its upward movement to obtain the volume adjustment from the product dose to the dosing pump (6).

The figures 4 and 5 , information on the movement of the piston and the action of the stop (5) on the piston (6a), a spring (6b) facilitates the descent of the piston (6a).

On the upper part of the pump dispenser (6) are also provided two other orifices. An orifice on which is placed an inlet valve (7) suction and loading product, slat or ball, for filling the metering pump (6), the positioning of the inlet valve (7) must allow pumping until the end of the sanitary product of the main tank (1). Figures 2 and 4 .

the other orifice is used to receive the outlet valve (8), slat or ball, the valve support (8c) connected to a sealed conduit (8a), and on the part upper connected to the pouring spout (8b) for feeding, at each upward cycle the auxiliary reservoir (15), a set dose of sanitary product, figure 2 .

An oblong recess passing through the diameter of the metering pump (6), the length or the spacing of this recess is slightly greater than the maximum projected stroke of the piston (6a). The piston (6a) is also drilled diametrically to receive a cylindrical pin (12) opening on either side in the oblong oblong metering pump (6) which serves as a guide. This assembly makes it possible to leave the piston (6a) free of a maximum axial movement equal to the length of the oblong recess. Figures 4 and 5 and detail figure 10 .

The piston (6a) receives on its upper part a two-way double-lip seal (9) resiliently hooked to a circular groove at the top of the piston and in its lower part is mounted by a forced cylindrical assembly the main float (10). ) which actuates, at each change of the water level in the toilet tank (2) the piston (6a), within the limit provided by the adjustable position of the stop rod (5) of the dosing pump (6), the lowering of the water level brings down the float (10) and the piston (6a) which draws the product from the treatment of the main tank (1) through the inlet flap to the slat or ball (7), the product is introduced also by gravitation which leads to self-priming and self-filling.

• Variante de réservoir annexe (15), ouvert avec fente de remplissage, figures 1, 2 et 7.
• Variante de réservoir annexe (15a), fermé et étanche, figure 8
• Variante de réservoir annexe (15b), ouvert à clapet entrant, figure 11

The auxiliary tank (15) can be proposed according to three variants:

• Auxiliary tank variant (15), open with filling slot, figures 1 , 2 and 7 .
• Variant of annex tank (15a), closed and waterproof, figure 8
• Variant of annex tank (15b), open with incoming flap, figure 11

Auxiliary tank variant (15), open with filling slot and adjusting slide (21), figures 2 and 7 . When filling the toilet tank (2), the rise of water immerses the float (20) which by its action on the lever (19) closes the exhaust valve (17). Then the rise of the water level immerses the float (10) which rises and its vertical thrust on the piston (6a) stops in contact with the stop adjustment rod (5) which determines the adjustment of the volume of the dose, materialized by the low and high positions of the piston (6a), figures 2 and 5 . The dose of product sucked and contained in the metering pump (6) above the two-lip seal (9), is transferred to the auxiliary tank (15) through the outgoing valve (8) and the conduit (8a) to to be poured by the pouring spout (8b) into the auxiliary tank (15).

Each toilet operating cycle a dose of product is transferred and injected into the auxiliary tank (15), depending on the setting.

The filling of the tank (2) continues and reaches its high level, the water fills the auxiliary tank (15) by the slot passing over the slide (21), detail figure 7 . The slide (21) must be set a few millimeters lower than the high water level of the toilet tank to let the water fill the auxiliary tank (15) and mix with the product coming from the spout (8b) to achieve pre-dilution With this position of the slide (21), if a variation of the level of the toilet tank occurs, the contents of the annex tank (15) will not be affected or dispersed in the water of the toilet tank.

When the toilet tank (2) is emptied, towards the end of the evacuation while there remains, while being evacuated in the tank (2), approximately 1.5 liters to flow, ie 4, 5 centimeters high, the float (20) mounted on the articulated lever (19) tilts and controls the instantaneous opening of the valve (17) which releases the column of pre-diluted product contained in the auxiliary tank (15). The pre-dilution of treatment product contained in the auxiliary tank (15) immediately mixes and evacuates with the end of the emptying, the treatment product, the final volume of which corresponds to the volume of the siphon is calculated not to be evacuated the sewer system, smeared all surfaces in its path, and finished draining and being recovered and retained in the siphon of the bowl to clean, disinfect and deodorize the toilet automatically and with each use of the toilet, the same operation is reproduced.

Variant of annex tank (15a), closed and waterproof, figure 8 During the filling of the toilet tank (2), the rise of the water immerses the float (20) which by its action on the lever (19) closes the discharge valve (17). Then, the rise of the water level immerses the float (10) which rises and its vertical thrust on the piston (6a) stops in contact with the stop adjustment rod (5) which determines the adjustment of the volume of the dose materialized by the low and high positions of the piston (6a), figures 2 and 5 .

The dose of product sucked and contained in the metering pump (6) above the two-lip seal (9), is transferred to the auxiliary tank (15a) through the valve (8) and the duct (8a) to be poured by the spout (8b) into the auxiliary tank (15a).

At each toilet operating cycle a dose of product is transferred and injected into this auxiliary tank (15a), depending on the setting made.

The water level continues to rise reaches the inlet valve (18), the sealed cover (16) retains the air in this auxiliary tank (15a) and the water is introduced by this valve to its level, then stops entering the tank (15a) due to the bell effect. The amount of water admitted is determined by the position of the inlet valve (18).

however, the inlet valve (18) passes and charges the reserve of air, due to the height of the water in the reservoir (2), in this auxiliary reservoir (15a). This reserve of air is compressed in the annex tank (15a) above the pre-dilution. The sealed connection of the duct (8a) and the lamella or ball outlet valve (8) and the inlet valve (18) do not allow any leakage or return and the pressure and pre-dilution can be released only by the opening of the evacuation valve (17), even if the level of the toilet water tank (2) was lowered without reaching the trigger level of the opening of the evacuation valve (17). The pressure of the air inside the auxiliary tank (15a) is in equilibrium with the external water pressure, making any leakage through the valves (17) and (18) impossible if the toilet tank is not empty.

The air volume of the auxiliary tank (15a) must be as large as possible to obtain better evacuation propulsion of the pre-dilution.

When using the toilet, once the water is being evacuated, at the precise moment, just at the end of the evacuation cycle, where the water level in the toilet tank causes the water to fall suddenly. float (20) there is only about one and a half liters of water at the end of the toilet tank float (20) mounted on the articulated lever (19) triggers the instantaneous opening of the discharge valve (17). The compressed air reserve contained inside the auxiliary tank (15a) immediately propels the opening of the outlet valve (17) pre-dilution in the current evacuation of the toilet tank (2). At this precise moment There is no more external pressure, the end of water evacuation of about a liter and a half with a dose of product is a solution of sanitary product correctly dosed. This product mixture covers and coats all of the interior surfaces of the water tank, the circulation ducts, attains, coats and adheres to all of the interior surfaces of the toilet bowl, this amount of treatment mixture, the volume of which final is the volume of the siphon is calculated to not be discharged to the sewer, eventually flow and be recovered and retained in the siphon of the bowl. The product will be able to act correctly over time on all these coated surfaces of product and between each use of the toilets to give the product the time of action in the same way as it is practiced in manual operation, to clean, disinfect and deodorize the product. interior set of toilets and use the minimum of product and water for this final operation. By its presence in the bowl, the product also acts on the siphon.

Variant of the annex tank (15b) open with inlet valve, figure 11 . As for the two previous variants, after the use of the toilet the rise of the water in the tank (2) immerses the float (20) which by its action on the lever (19) closes the check valve ( 17) then: figure 2 , the rise of the water level immerses the float (10) which rises and pushes the piston (6a), the vertical upward movement of the piston (6a) stops in contact with the thrust adjustment adjusting rod (5) the volume of the dose materialized by the low and high positions of the piston by the figures 4 and 5 . The dose of product sucked and contained above the double-lip seal (9) of the metering pump (6) is transferred, via the outlet valve (8) along the duct (8a) to be discharged by the spout ( 8b) in the auxiliary tank (15b), the filling of the tank (2) continues and reaches the inlet valve (18) the water enters and continues to fill the auxiliary tank (15b) at the same water level only in the tank (2) which constitutes a column of pre-diluted product. The pressure at the inside and outside of the auxiliary tank (15b) is identical and the valve (18) opposes any liquid outlet if the external level drops without reaching the float (20). If a change in the level of the toilet tank occurs, the contents of the annex tank (15b) will not be affected or dispersed in the water of the toilet tank. The inlet valve (18) for this alternative tank variant (15b) can be placed between the low and high water levels of the toilet tank.

When emptying the toilet tank (2), towards the end of the evacuation while there remains about 1.5 liter to flow or 4.5 centimeters of water height, the float (20) mounted on the articulated lever (19) tilts and controls the instantaneous opening of the discharge valve (17) which releases the pre-dilution column from the treatment product contained in the reservoir (15b). At this precise moment, there is no more water and external pressure, the pre-dilution immediately mixes and is evacuated with the end of the emptying, the treatment product, whose final volume corresponds to the volume of the siphon is calculated not to be discharged to the sewers, smeared all surfaces in its path, it eventually flow and be recovered and retained in the siphon of the bowl.

Then the filling cycle resumes, and the water rises in the toilet tank (2).

the automatic dispenser dosing pump with adjustable volume, figures 1 , consists of the diaphragm metering pump version (4c) and the auxiliary tank variant (15) with filling slot and slide (21) figure 3 and 7 .

The operation of this version of automatic dispensing pump dosing volume adjustable diaphragm (4c), figures 1 and 3 , is identical to the piston version (6), only its design is less laborious. The screwed or notched connection of the pump dispenser (4) makes it possible to tighten the diaphragm (4c), the seal (4b) and the upper part of the pump (4a) with the reservoir (1) on its periphery. . The plate (4e) fixes the membrane (4c) to the pusher (4d). The membrane (4c) must be flexible and inelastic.

When emptying the toilet tank (2), the float (10) mounted on the pusher (4d) pulls down the membrane (4c) attached to the pusher (4d) by the plate (4e). The product of the tank (1) is introduced by the inlet valve (7) and filled with the upper part of the membrane (4c) towards the end of the evacuation while there is still about 1.5 liters to flow or 4.5 centimeters of water in the tank (2), the float (20) tilts and actuates with the articulated lever (19) the instantaneous opening of the discharge valve (17) which releases the pre-dilution column from the treatment product contained in the auxiliary reservoir (15). At this precise moment, there is no more external pressure, as soon as the pre-dilution mixes and is evacuated with the end of the emptying, the treatment product, whose final volume corresponds to the volume of the siphon, is calculated to not be drained to the sewer, plastered and adhered to all surfaces in its path, the mixture eventually flowing and being recovered and retained in the siphon of the bowl.

After draining, the filling of the toilet tank (2) begins. The rise in the water level immerses the float (20) which by its action on the lever (19) closes the discharge valve (17), then the rise in the water level immerses the float (10) which rises and its vertical thrust on the pusher piston (4d) and on the membrane (4c) stops in contact with the stop adjustment rod (5) which determines the adjustment of the volume of the dose. The dose of product sucked and contained in the metering pump (4) above the membrane (4c) is transferred to the auxiliary tank (15) through the valve (8) following the conduit (8a) to be discharged by the spout (8b) in the auxiliary tank (15).

The filling of the tank (2) continues and reaches its high level, the water fills the auxiliary tank (15) by the slot by passing over the slide (21), figures 1 and 7 . The slide (21) must be set a few millimeters lower than the high water level of the toilet tank to let the water fill the tank (15) and mix with the product coming from the spout (8b), if a variation of the level of the toilet tank occurs, the contents of the annex tank (15) will not be affected or dispersed in the water of the toilet tank.
