The present invention is in the field of cleaning substances. More specifically, the invention relates to a soluble detergent unit for industrial dishwashers.
Industrial dishwashers are essential equipment for enabling high-volume organizational and industrial kitchens, such as restaurants, to serve high volumes of people while using a predetermined limited number of dining sets.
The operation of industrial dishwashers includes cycling a predetermined volume of water stored in a reservoir and applied onto the washed dishes, while a cleaning agent in the form of liquid/gel/powder/tablet is added to the water.
Many industrial dishwashers employ ancillary electric detergent dispensers for controllably adding detergents to the dishwasher water reservoir. Unfortunately, the existing detergent dispensers require professional installation and maintenance, incurring significant purchase and service costs.
The incurred costs can be reduced by manually adding detergent powders or tablets. However, existing detergent powders/tablets provide the dishwasher user with no indication of when the added powders/tablets deplete, which is commonly detected when washed dishes that finish a washing cycle remain dirty. This results in wasted water, electricity, and time.
Therefore, it is an object of the present invention to provide a soluble detergent unit, which indicates detergent depletion before its concentration in the water degrades.
Other objects and advantages of the invention will become apparent as the description proceeds.
The invention relates to a soluble detergent unit that comprises a floatable and substantially hollow container adapted to accommodate a desired volume of one or more portions of a soluble substance, at least one of which is a soluble detergent, wherein said floatable and substantially hollow container is configured to allow a predetermined contact between the soluble detergent and the surrounding water, thereby enabling the gradual release of soluble detergent to the water at a predetermined rate, and wherein said soluble detergent unit is adapted to initially submerge in water, and to float towards the water level along with the gradual release of soluble detergent to the water. Thereby providing the dishwasher users with an early indication—before the detergent concentration in the water deteriorates.
According to an embodiment of the invention, the floatable and substantially hollow container is substantially cylindrical.
According to an embodiment of the invention, the floatable and substantially hollow container comprises one or more inwardly extending protrusions.
According to an embodiment of the invention, the floatable and substantially hollow container is made of reusable materials.
According to an embodiment of the invention, the floatable and substantially hollow container adapted with a well notable color.
According to an embodiment of the invention, the floatable and substantially hollow container is shaped like a cup.
According to an embodiment of the invention, the floatable and substantially hollow container comprises lateral apertures.
According to an embodiment of the invention, the floatable and substantially hollow container is partitioned.
According to an embodiment of the invention, the floatable and substantially hollow container comprises one or more cylindrical partitions.
The above and other characteristics and advantages of the invention will be better understood through the following illustrative and non-limitative detailed description of preferred embodiments thereof, with reference to the appended drawings, wherein:
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.
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 level—as 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 indication—before the detergent concentration in the water deteriorates.
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.
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.
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.
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.
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.
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).
Detergent 120 may comprise two or more portions 120a and 120b (
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
Floatable cup 310 of soluble detergent unit 300 (
Another partitioned configuration is soluble detergent unit 400 of
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.
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.
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.
