Description

The present invention relates to a device for dispensing in the flushing water and/or for mixing with the flushing water detergent and/or sanitizing and/or deodorant products, in toilet bowls or hydraulic and sanitary fixtures in general.
Devices for dispensing, within toilet bowls, detergent and/or sanitizing and/or deodorant products in the solid state, packaged in the form of water-soluble tablet or bar, are known. Such devices are constituted generally by a supporting structure, which is composed of an enclosure with a cage-like structure which defines internally a compartment for the tablet or bar and a hook-shaped suspension arm, which is connected to the enclosure and can engage the rim of the toilet bowl so as to support the enclosure below the rim of the toilet bowl, where the holes for dispensing the flushing water of the toilet bowl are provided. In this manner, every time the flushing system of the toilet bowl is operated, the flushing water strikes the enclosure, gradually dissolving the tablet or bar and therefore mixing the detergent and/or sanitizing and/or deodorant products with the flushing water.
When using such devices, very often a scarcely uniform wear of the tablet or bar is observed, because the flushing water strikes in a different manner the various regions of the tablet or bar. This scarcely uniform wear has the effect of producing very often an unwanted breakup of the tablet or bar, with the release of undissolved pieces into the flushing water and therefore with a scarcely effective wear of the tablet or bar in terms of washing the toilet bowl.
Moreover, with such devices the substances that compose the tablet or bar dissolve in the flushing water in a scarcely satisfactory manner, and foam generation is limited and is usually enhanced by increasing the content of surfactants in the products that compose the tablet or bar.
Devices for dispensing into toilet bowls detergent and/or sanitizing and/or deodorant products in the liquid or gel state are also known. Such devices are provided with at least one tank, which is hung from the rim of the toilet bowl and contains the detergent and/or sanitizing and/or deodorant products, and the products are dispensed into the flushing water usually by utilizing the washing action of the water on a preset region of the device, onto which a certain quantity of the cited products is dispensed generally by gravity.
Even with these devices, very often the mixing of the detergent and/or sanitizing and/or deodorant products in the flushing water is not fully satisfactory and foam generation is limited and conditioned by the shape of the toilet bowl, by the force of the water jet, and by the direction of the flushing water on the device.
In toilet bowls served by a cistern for storing the flushing water, the flushing water can receive the addition of detergent and/or sanitizing and/or deodorant products, which are placed inside said cistern.
In this case also, very often the mixing of the detergent and/or sanitizing and/or deodorant products in the flushing water is not fully satisfactory and foam generation is limited.
WO 2004/005631 discloses a device for cleaning and disinfecting a toilet using a liquid composition, which comprises a tilting tray below a liquid composition tank.
GB-A-2 349 157 discloses a device for dosing an active agent into the flushing water of a toilet, in which the active agent is inside a partially rotating tank.
DE-A-199 20 897 discloses a device for cleaning a toilet, in which a tank is arranged so as to release a dose of liquid sanitizing product to between the paddles of a rotating element.
The aim of the present invention is to provide a device for dispensing into the flushing water and/or for mixing with the flushing water detergent and/or sanitizing and/or deodorant products, in toilet bowls or hydraulic and sanitary fixtures in general, which ensures optimum mixing of the detergent and/or sanitizing and/or deodorant products with the flushing water.
Within this aim, an object of the invention is to provide a device which, for equal detergent and/or sanitizing and/or deodorant products used, achieves a greater generation of foam and a longer retention of the generated foam with respect to known types of devices.
Another object of the invention is to provide a device which can be manufactured at competitive costs and is simple to use.
This aim and these and other objects, which will become better apparent hereinafter, are achieved by a device for dispensing into the flushing water and/or for mixing with the flushing water detergent and/or sanitizing and/or deodorant products, in toilet bowls or hydraulic and sanitary fixtures in general, according to claim 1.

With reference to the figures, the device according to the invention, generally designated in its various embodiments by the reference numerals 1a, 1b, 1c, 1d, 1e, 1f, 1g, 1h, 1i, comprises a supporting structure 2a-2i, which is provided with engagement means 3a-3i, which can engage the hydraulic and sanitary fixture so as to support the supporting structure 2a-2i in a region of the fixture that is affected by the flow of the flushing water.
According to the invention, the supporting structure 2a-2i supports, so that it can rotate about a rotation axis 4a-4i, at least one rotating element 5a-5i, which interacts with the flow of the flushing water in order to mix detergent and/or sanitizing and/or deodorant products introduced in the flushing water and/or adjust the dispensing of detergent and/or sanitizing and/or deodorant products connected to the supporting structure 2a-2i and/or vary the orientation of the flow of flushing water conveyed onto detergent and/or sanitizing and/or deodorant products connected to the supporting structure 2a-2i.
The rotating element 5a, 5b, 5c, 5d, 5e, 5f, 5g, 5h can be constituted by an impeller with radial vanes or of the screw type in which the rotation axis, considering the device during use, i.e., with the supporting structure 2a, 2b, 2c, 2d, 2e, 2f, 2g, 2h supported by the engagement means 3a, 3b, 3c, 3d, 3e, 3f, 3g, 3h in a region of the fixture affected by the flow of the flushing water, is oriented substantially horizontally.
As an alternative, the rotating element 5i can be constituted by a helical impeller in which the rotation axis, considering the device during use, i.e., with the supporting structure 2i supported by the engagement means 3i in a region of the fixture affected by the flow of the flushing water, is oriented substantially vertically.
The detergent and/or sanitizing and/or deodorant products to be dispensed are supported preferably by the supporting structure 2a-2i so that they are external to the rotating element, e.g. they are placed upstream of or downstream of the rotating element with respect to the direction of the flushing water flow. The detergent and/or sanitizing and/or deodorant products can also be arranged within the cistern for storing flushing water with which the toilet bowl or the hydraulic and sanitary fixture in general is equipped. In this last case, the device according to the invention is constituted substantially by the supporting structure, by the engagement means and by the rotating element, which by interacting with the flow of the flushing water mixes the detergent and/or sanitizing and/or deodorant products that are already present in the flushing water and generates a larger volume of foam for an equal composition of the products.
With reference to Figures 1 and 2, the device 1a in the first embodiment comprises a supporting structure 2a, which is constituted substantially by an enclosure composed of two parts 7a, 8a, which are mutually assembled and define a compartment 9a inside them. Such compartment 9a is connected to the outside through openings 10a, which are designed to be directed toward the wall of the fixture along which the flushing water flows, and optionally openings 11a on its opposite side.
The rotating element 5a is constituted, in this first embodiment, by an impeller 6a with radial vanes which taper in the direction of their axial ends. The impeller 6a is supported, so that it can rotate about its own axis 4a, by the supporting structure 2a within the compartment 9a. The axis 4a of the impeller 6a, when the device is being used, is arranged substantially horizontally.
The detergent and/or sanitizing and/or deodorant products to be mixed with the flushing water are also arranged inside the compartment 9a. Such products are solid and are packaged in the form of at least one water-soluble tablet. Preferably, the detergent and/or sanitizing and/or deodorant products are packaged in the form of two water- soluble tablets 12a, 13a, which are positioned in the compartment 9a above the impeller 6a.
Conveniently, between the impeller 6a and the tablets 12a, 13a there is an interposed diaphragm 14a, which supports the tablets 12a, 13a. The diaphragm 14a is crossed by passages 15a, which allow the flushing water that makes contact with the tablets 12a, 13a and the products of the dissolution of the tablets 12a, 13a to flow on the vanes of the underlying impeller 6a.
In practice, when using the device in this first embodiment, the flushing water enters the compartment 9a through the openings 10a, 11a located in the upper part of the supporting structure 2a, comes into contact with the tablets 12a, 13a, causing their gradual dissolution, and then descends onto the impeller 6a, causing its rotation about its own axis 4a before exiting from the openings 10a located on the lower part of the supporting structure 2a.
In this first embodiment, the impeller 6a performs predominantly the function of improving the mixing of the products of the dissolution of the tablets 12a, 13a with each other and with the flushing water, increasing the production of foam.
With reference to Figures 3 and 4, the device 1b in the second embodiment is provided substantially like the device described above with reference to the first embodiment shown in Figures 1 and 2, with the difference that the rotating element 5b is constituted, in this second embodiment, by an impeller 6b of the screw or screw-feeder type, the rotation axis 4b whereof is horizontal when the device is in use.
The other elements of the device in this second embodiment that correspond to the elements already described with reference to the first embodiment shown in Figures 1 and 2 have been designated by the same reference numerals followed by the letter b instead of the letter a.
In practice, in the use of the device in this second embodiment, the flushing water enters the compartment 9b through the openings 10b, 11b located in the upper part of the supporting structure 2b, comes into contact with the tablets 12b, 13b, causing their gradual dissolution, and then descends onto the impeller 6b, causing its rotation about its own axis 4b before flowing out through the openings 11b located in the lower part of the supporting structure 2b.
In this second embodiment also, the impeller 6b performs predominantly the function of improving the mixing of the products of the dissolution of the tablets 12b, 13b with each other and with the flushing water, increasing the production of foam. Moreover, the particular shape of the impeller 6b also directs laterally the flow of water mixed with the products of the dissolution of the tablets 12b, 13b in output from the device, thus extending the area of the action of the products on the walls of the bowl and achieving a more diffuse action which is not limited only to the region that lies below the device.
With reference to Figures 5 and 6, the device 1c in the third embodiment comprises a supporting structure 2c, which is constituted substantially by an enclosure composed of two parts 7c, 8c, which are mutually assembled and define internally a compartment 9c. Such compartment 9c is connected to the outside through openings 10c, which are designed to be directed toward the wall of the fixture along which the flushing water flows, and optionally openings 11c on its opposite side.
The rotating element 5c is constituted, in this third embodiment, by an impeller 6c with radial vanes which taper in the direction of their axial ends. The impeller 6c is supported, so that it can rotate about its own axis 4c, by the supporting structure 2c within the compartment 9c. The axis 4c, when the device is in use, is arranged substantially horizontally.
The detergent and/or sanitizing and/or deodorant products to be mixed with the flushing water are also arranged within the compartment 9c. In this third embodiment, part of these products is in solid form, packaged in the form of at least one water-soluble tablet 12c, and part is in liquid or gel form and is contained within a tank 13c.
The tablet 12c and the tank 13c are arranged in the compartment 9c above the impeller 6c.
Conveniently, between the impeller 6c and the assembly constituted by the tablet 12c and the tank 13c, there is an interposed diaphragm 14c, which supports the tablet 12c and the tank 13c. The diaphragm 14c is crossed by passages 15c and by a hole 16c, which allow the flushing water that makes contact with the tablet 12c, the products of the dissolution of the tablet 12c, and the liquid or gel products dispensed by the tank 13c to flow on the vanes of the underlying impeller 6c.
More particularly, the tank 13c has at least one dispensing outlet at its lower end, which is not visible in the figures. The dispensing outlet of the tank 13c is arranged at a hole 16c, which is provided in the diaphragm 14c. Below the hole 16c, the supporting structure 2c supports a retention element, which is constituted for example by a plate 17c. The plate 17c is arranged at a preset distance from the hole 16c and is designed to retain preset quantities of the liquid or gel products that exit by gravity from the dispensing outlet of the tank 13c, preventing their excessive spread.
In this third embodiment, the impeller 6c is arranged below the plate 17c, but it might also be arranged between the diaphragm 14c, in which the hole 16c is provided, and the plate 17c, cooperating with the plate 17c in retaining the liquid or gel products dispensed by the tank 13c.
In practice, in the use of the device in this third embodiment, the flushing water enters the compartment 9c through the openings 10c, 11c located in the upper part of the supporting structure 2c, comes into contact with the tablet 12c, causing its gradual dissolution, and with the liquid or gel product deposited on the plate 17c. The flushing water, together with the products of the dissolution of the tablet 12c and the products dispensed by the tank 13c, then descends onto the impeller 6c, causing its rotation about its own axis 4c before it flows out from the openings 10c located on the lower part of the supporting structure 2c.
In this third embodiment, the impeller 6c performs predominantly the function of improving the mixing of the products of the dissolution of the tablet 12c and of the products dispensed by the tank 13c with each other and with the flushing water, increasing the generation of foam.
With reference to Figures 7 and 8, the device 1d in the fourth embodiment is provided substantially like the device already described with reference to the first embodiment shown in Figures 1 and 2, with the difference that the impeller 6d is further connected to actuation means which can turn it about its own axis 4d in addition to the action of the flushing water on said impeller 6d.
More particularly, said actuation means preferably comprise an electric motor and an electric power source for supplying it, such as for example a battery, which are arranged inside a hermetically sealed container 18d supported by the supporting structure 2d. The electric motor is connected, by means of its output shaft, to the impeller 6d so as to cause its rotation about the axis 4d with respect to the supporting structure 2d. The electric motor can be controlled by an electronic circuit, which is also accommodated within the container 18d and drives the electric motor with a preset rotation rate when the impeller 6d is turned about its own axis 4d by the flow of the flushing water and interrupts its actuation after a period of time which can be preset.
The other elements of the device in this fourth embodiment that correspond to the elements already described with reference to the first embodiment shown in Figures 1 and 2 have been designated by the same reference numerals followed by the letter d instead of the letter a.
In practice, the operation of the device in this fourth embodiment is similar to the one already described with reference to the device in the first embodiment, with the difference that the rotation rate of the impeller 6d about its own axis 4d and the rotation time of the impeller 6d can be increased at will by means of the electric motor that drives the impeller 6d so as to further improve the effect of mixing the products of the dissolution of the tablets 12d, 13d with each other and with the flushing water and increase the generation of foam.
With reference to Figures 9 and 10, the device 1e in the fifth embodiment is provided in a manner which is similar to the device in the first embodiment shown in Figures 1 and 2, with the difference that in this fifth embodiment the impeller 6e is connected to means which are adapted to prolong its rotation activated by the flow of the flushing water.
Such means adapted to prolong the rotation of the impeller 6e comprise a flywheel 19e, which is supported, so that it can rotate about its own axis, by the supporting structure 2e and is connected to the impeller 6e cynematically, by means of gears 20e, 21 e also supported by the supporting structure 2e.
The other elements of the device in this fifth embodiment that correspond to the elements already described with reference to the first embodiment shown in Figures 1 and 2 have been designated by the same reference numerals followed by the letter e instead of the letter a.
In practice, in the use of the device in this fifth embodiment, the flushing water enters the compartment 9e through the openings 10e, 11e located in the upper part of the supporting structure 2e, comes into contact with the tablets 12e, 13e, causing their progressive dissolution, and then descends onto the impeller 6e, causing its rotation about its own axis 4e before flowing out from the openings 10e located on the lower part of the supporting structure 2e. The rotation of the impeller 6e about its own axis 4e is prolonged by the presence of the flywheel 19e.
In this fifth embodiment, the impeller 6e performs predominantly the function of improving the mixing of the products of the dissolution of the tablets 12e, 13e with each other and with the flushing water, increasing the generation of foam.
With reference to Figures 11 and 12, the device 1f in the sixth embodiment comprises a supporting structure 2f, which is constituted substantially by an enclosure composed of two parts 7f, 8f, which are mutually assembled and define internally a compartment 9f. Said compartment 9f is connected to the outside through openings 10f, which are designed to be directed toward the wall of the fixture along which the flushing water flows, and optionally openings 11f on its opposite side.
The rotating element 5f is constituted, in this sixth embodiment, by a screw-type impeller 6f. The impeller 6f is supported, so that it can rotate about its own axis 4f, by the supporting structure 2f within the compartment 9f. The axis 4f, when the device is in use, is arranged substantially horizontally.
The detergent and/or sanitizing and/or deodorant products to be mixed with the flushing water are arranged within the compartment 9f, downstream of the impeller 6f with respect to the direction of the flushing water. Said products are solid and packaged in the form of a water-soluble tablet 12f. As an alternative, two or more tablets can be arranged within the compartment 9f.
In this sixth embodiment, the impeller 6f is arranged above the tablet 12f and distributes the flow of flushing water that enters the compartment 9f onto the tablet 12f so as to achieve a more uniform and effective wear of the tablet 12f.
For this reason, the impeller 6f can be provided, as shown, with two mutually opposite cylindrical helical elements, which protrude from the center of the impeller toward the axial ends, so as to convey the flushing water also onto peripheral regions of the tablet 12f, which otherwise would be reached only partially by the flushing water.
In practice, in the use of the device in this sixth embodiment, the flushing water enters the compartment 9f through the openings 10f, 11f located in the upper part of the supporting structure 2f. The flushing water makes contact with the impeller 6f and causes it to turn about its own axis 4f. The impeller 6f, by means of its rotation, changes the direction of the flow of the flushing water, distributing it uniformly on the tablet 12f, which is progressively dissolved by the passage of the flushing water. The flushing water with the products of the dissolution of the tablet 12f then exits through the openings 10f located in the lower part of the supporting structure 2f. In this case also, although the impeller 6f predominantly performs the function of modifying the path of the water stream that passes through the compartment 9f, by coming in any case into contact with the flushing water and with the products of the dissolution of the tablet 12f it mixes said products with the flushing water, increasing the generation of foam.
With reference to Figures 13 and 14, the device 1g in the seventh embodiment comprises a supporting structure 2g, which supports a tray-like container 20g and has, below said tray-like container 20g, a portion 7g which defines a compartment 9g, which is open laterally and in a downward region and in which the rotating element 5g, constituted by an impeller 6g with radial vanes, is arranged. When the device is in use, the rotation axis 4g of the impeller 6g is arranged substantially horizontally.
In this seventh embodiment, the detergent and/or sanitizing and/or deodorant products to be mixed with the flushing water are solid and are packaged in the form of a bar 12g, which is accommodated in the tray-like container 20g. As an alternative, two or more bars might be arranged in the tray-like container 20g.
The tray-like container 20g has, on its bottom, at least one opening 15g for the release of the water and of the detergent and/or sanitizing and/or deodorant products produced by the dissolution of the bar 12g, onto the vanes of the impeller 6g arranged below.
In this seventh embodiment, since the tray-like container 20g is open upwardly, the bar 12g is exposed to the flow of flushing water and the tray-like container 20g is designed to collect part of the flushing water and of the products of the dissolution of the bar 12g in order to release them gradually, even after the flow of the flushing water has ceased, onto the impeller 6g. This seventh embodiment is particularly adapted to achieve the dispensing of products which have a better performance if they can remain in the toilet bowl after the flow of flushing water has ceased, such as for example scale removers, whiteners or fragrances.
In this seventh embodiment also, the impeller 6g effectively performs the function of mixing the flushing water with the products of the dissolution of the bar 12g and of increasing the production of foam.
In practice it has been found that the device according to the invention fully achieves the intended aim, since it improves the mixing of the detergent and/or sanitizing and/or deodorant products with the flushing water and achieves, for an equal formulation of the detergent and/or sanitizing and/or deodorant products used, a higher production of foam and a longer permanence of the generated foam with respect to known types of devices.
Thanks to this fact, it is possible to reduce the percentage of surfactants in the composition of the detergent and/or sanitizing and/or deodorant products used.
In practice, the materials used, as well as the dimensions, may be any according to requirements and to the state of the art.
Where technical features mentioned in any claim are followed by reference signs, those reference signs have been included for the sole purpose of increasing the intelligibility of the claims and accordingly such reference signs do not have any limiting effect on the interpretation of each element identified by way of example by such reference signs.
