A DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION

[0022] The present invention relates to a soluble detergent unit intended for placement in an industrial dishwasher's water reservoir to gradually release detergent agents to the surrounding water in a controllable manner, such as to maintain a predetermined detergent concentration in the water.

[0023] The proposed soluble detergent unit is adapted to submerge in water initially, then to gradually float along with the gradual release of detergent into the water, such as to be notable near/at the water levelas the detergent depletes (i.e., when no further detergent can be released to the water), thereby to provide the users of the dishwasher with an early indicationbefore the detergent concentration in the water deteriorates.

[0024] In the following detailed description, references are made to several embodiments of the present invention, examples of which are illustrated in the accompanying figures. The figures depict embodiments of the present invention for purposes of illustration only. One skilled in the art will readily recognize from the following description that the described embodiments may be combined, alternative embodiments may be utilized, and other changes may be made without departing from the spirit or scope of the present invention described herein.

[0025] The terms for example, e.g., and optionally, as used herein, are intended to be used to introduce non-limiting examples. While certain references are made to certain example configurations/combinations of elements, other configurations/combinations can also be used. Furthermore, the example elements may be combined into fewer components and/or divided into further components.

[0026] FIGS. 1A-1B schematically illustrate perspective and cross-section views of a soluble detergent unit 100, according to an embodiment of the present invention. Soluble detergent unit 100 comprises a floatable and substantially hollow container such as floatable cup 110, which is adapted to accommodate the desired volume of soluble detergent 120, while allowing a predetermined contact between the soluble detergent and the surrounding water, thereby enabling releasing soluble detergent 120 to the water gradually (e.g., within a dishwasher water tank) at a predetermined dissolving rate. Floatable cup 110 may further comprise one or more inwardly extending protrusions 110a for maintaining firm contact with detergent 120, thus, the integrity of unit 100.

[0027] The dissolving rate of detergent 120 is derived from its chemical properties and its overall contact area with the surrounding water. For example, whereas the floatable cup 110 is water-resistant, the contact area of detergent 120 with the surrounding water is determined by the internal diameter of the floatable cup 110.

[0028] The average specific weight of floatable cup 110 with soluble detergent 120 is initially higher than the specific weight of water. When unit 100 is placed in a water reservoir, it submerges. Nevertheless, floatable cup 110 is formed with a lower specific weight than the specific weight of water (e.g., comprising a plastic comprising air bubbles) to enable the gradual floating of unit 100 along with the gradual release of soluble detergent 120. According to an embodiment of the present invention, cup 110 is adapted with a notable color (e.g., obtained by added bright color paint and/or by the color of the comprising detergent compound) to ensure notable visibility of unit 100.

[0029] Of course, multiple different materials may be selected by one skilled in the art for fabricating floatable cup 110 with a specific weight lower than the specific water weight. For instance, floatable cup 110 may be reusable (i.e., can be recollected, cleaned, and refilled) and/or made of reusable materials such as reusable polymers.

[0030] Detergent 120 is a compound of one or more soluble substances (e.g., alkali agents that breaks into soluble powder in water) at a predetermined dissolving rate in water, for enduring a predetermined number of cleaning cycles, at a given water volume and suitability for desired cleaning intensity (e.g., alternate subtypes of unit 100 may be provided for different grades of water volumes and required cleaning intensity, hence, can be selected by users in accordance with a specific combination of a dishwasher, dishes type and dirt to be cleaned (e.g., specific food types served in a particular restaurant that leaves food residues of specific persistency).

[0031] Detergent 120 may comprise two or more portions 120a and 120b (FIG. 1B) of soluble detergents, each of which has different characteristics. For example, portion 120a may be a booster portion of a higher dissolving rate than portion 120b, such as to enable a faster detergent release rate, thereby shortly (e.g., within a few seconds) reaching a proper detergent concentration in a new volume of added water (e.g., for the first cleaning cycle in a restaurant's shift).

[0032] FIG. 2 schematically illustrates a cross-section view of a soluble detergent unit 200 having a floatable cup 210 with one or more lateral release apertures 210a, according to an embodiment of the present invention. Lateral apertures 210a (a single aperture illustrated in FIG. 2) enable simultaneous release of matter from portions 120a and 120b, to obtain a desired mixture of dissolved substances from portions 120a and 120b in the water.

[0033] According to some embodiments of the invention, a mixture of dissolved detergents is obtained by utilizing partitioned configurations of soluble detergent unit 100 or 200, such as by using a partitioned floatable container, as illustrated in FIGS. 3 and 4.

[0034] Floatable cup 310 of soluble detergent unit 300 (FIG. 3) is cylindrically partitioned by partition 301, thus facilitating a gradual release of a soluble substance 320. The dissolving rate of soluble substance 320, as well as its relative quantity in the mixture of substances released to the water (i.e., with respect to the released substance of portion 120a or 120b), are determined by its chemical properties, the size and shape of partition 301 and the relative proportions of partition 301 and cup 310.

[0035] Another partitioned configuration is soluble detergent unit 400 of FIG. 4, which comprises a mediating partition 401, thus enabling the simultaneous release of two substances into the water.

[0036] One skilled in the art will readily realize numerous alternate shapes and dimensions of partitions 301 and 401, resulting in desired relative volumes of the partitioned portions, as well as combinations of multiple cylindrical and/or mediating partitions, to facilitate a gradual release of two or more detergents and/or other substances to the water.

[0037] Furthermore, while embodiments of the proposed soluble detergent unit are described hereinabove, and illustrated in the corresponding figures as having a substantially cylindrical shape and specific proportions, alternate shapes and configurations may be selected by one skilled in the art for specific implementations.

[0038] Although embodiments of the invention have been described by way of illustration, it will be understood that the invention may be carried out with many variations, modifications, and adaptations, without exceeding the scope of the claims.
