Description

[Technical Field]

[0001] (Priority) This application claims the benefit of U.S. Provisional Application No. 63 / 494,562, filed on 6 April 2023, which is incorporated herein by reference in its entirety.

[0002] (Field of invention) This patent application relates, in general terms, to a system for distributing a detergent solution from solid detergent into a dishwasher. In various embodiments, the present invention includes an apparatus for a dishwasher comprising a washing chamber and configured to perform each cleaning cycle including a washing period and a rinsing period, the system comprising a dispenser and a device for detecting a low detergent content in the washing liquid, the dispenser for distributing a detergent solution from solid detergent into the dishwasher, and the set comprising a liquid inlet interchangeable with the dispenser. The present invention also provides a method for distributing the detergent solution from the dispenser in a dishwasher capable of performing each cleaning cycle including a washing period and a rinsing period. [Background technology]

[0003] A dishwasher, also called an item washing machine or item washing machine, is a machine for automatically washing items such as dishes, trays, laboratory equipment, tableware, and kitchen utensils. A batch of items to be washed (e.g., dishes) is placed in a dishwasher tank, which typically includes racks and utensil holders, and can be washed in a cleaning cycle that includes wash and rinse periods. During the wash period, a cleaning mixture formed by water and dishwasher detergent is sprayed into the tank to be sprayed onto the dishes. The majority of the cleaning mixture is then retained in the tank, while a small portion is discharged before the rinse period begins (and refilled during the rinse period). During the rinse period, water is sprayed into the washing chamber to remove any residue of the cleaning mixture. After the rinse period is complete, the dishes can optionally be dried using air and / or heat during a drying period. A dishwasher may have various user-selectable settings for each cleaning cycle. These settings can define, for example, time, temperature, and the number of repetitions of each wash, rinse, and dry period. Additionally, this setting allows users to choose which time periods to include (for example, rinse only, dry only, rinse and dry, or wash and rinse without drying).

[0004] A typical household dishwasher is an under-counter unit designed to be installed beneath the kitchen counter. Other types of dishwashers include industrial or commercial dishwashers for use in restaurants, hotels, and other commercial establishments that provide food and beverage services, such as hood-type dishwashers. The dishwasher detergents used in these dishwashers may contain chemicals capable of cleaning, disinfecting, and / or reducing the surface tension of water (and thus water spots on dishes). Such dishwasher detergents are manufactured in various solid and liquid forms. Solid dishwasher detergents include chemicals manufactured in the form of solid blocks, such as tablets in various shapes.

[0005] The technical field of this application specifically refers to a system configured to allow each load of solid detergent to last for multiple cleaning cycles.

[0006] One drawback of conventional systems is that dishwasher detergent must be added before each cleaning cycle, or existing solid detergent dispensers that can supply detergent solution over multiple cleaning cycles are bulky because they require electronic equipment and water atomizers to dissolve the solid detergent. Furthermore, installation methods that would allow the detergent solution to be distributed to an existing dishwasher over multiple cleaning cycles fail because there is limited space in the washing chamber required for additional dispensers and storage space for solid detergent sufficient to withstand several cleaning cycles. Further drawbacks relate to the effort required to provide an appropriate dosage of detergent solution and for the user to visually confirm whether sufficient solid detergent is present. A further problem is that changing the type of detergent—from liquid detergent to solid detergent, or from one detergent per cleaning cycle to one that lasts over multiple cleaning cycles—necessitates either replacing the dishwasher or upgrading an existing dishwasher at a time-consuming and costly expense.

[0007] The present invention provides an apparatus and method for overcoming these drawbacks. [Overview of the project]

[0008] To address these and other drawbacks, the present invention includes a system for distributing a detergent solution from a solid detergent into a dishwasher, the dishwasher including a washing chamber and capable of performing each cleaning cycle including a washing period and a rinsing period, the system including a dispenser for dissolving a solid detergent block and distributing the detergent solution, and a battery-powered device including a control unit and a conductivity sensor.

[0009] The present invention relates to a specific dispenser for distributing a detergent solution from a solid detergent into a dishwasher.

[0010] Furthermore, the present invention relates to a set comprising a dispenser for distributing a detergent solution from a solid detergent into a dishwasher, and one or more interchangeable elements forming a liquid inlet for the dispenser.

[0011] The present invention further relates to a method for dispensing a detergent solution from a dispenser in a dishwasher capable of performing each cleaning cycle, including a washing period and a rinsing period.

[0012] The present invention also relates to the use of the above-mentioned system or dispenser or set, and to the removal and / or operation of a dishwasher having said system.

[0013] Furthermore, the present invention provides a dishwasher comprising the system and / or a dishwasher configured to perform the method of the present invention.

[0016] The following detailed description of the subject matter refers to the subject matter of the accompanying drawings, which illustrate specific embodiments and forms in which the subject matter may be practiced. These embodiments are described in sufficient detail to enable those skilled in the art to practice the subject matter. References to "certain", "one", or "various" embodiments in the present disclosure do not necessarily refer to the same embodiment, and such references contemplate multiple embodiments. The scope of the present invention is defined by the appended claims, together with the full scope of legal equivalents to which such claims are entitled.

[0017] Specifically, the present invention provides the following.

[0018] [System] The present invention provides a system for dispensing a detergent solution from a solid detergent into a dishwasher, the dishwasher including a washing chamber and being capable of performing each cleaning cycle including a washing period and a rinsing period, The system is A dispenser for dissolving a solid detergent block and dispensing a detergent solution, - accommodating an amount of solid detergent block sufficient to provide a detergent solution for at least 10 cleaning cycles, - being removably retrofittable to the dishwasher, when removably attached to the inner wall within the washing chamber of the dishwasher, - collecting water or liquid sprayed into the washing chamber through a liquid inlet, - The collected water or liquid is guided into a solid detergent block contained in a dispenser, thereby causing a portion of the solid detergent block to dissolve and a detergent solution to be formed. -A dispenser configured to enable the continuous release of all detergent solution once the detergent solution is formed, A battery-powered device including a control unit and a conductivity sensor, which operates independently of a dishwasher and is configured to be removable and retrofittable to a dishwasher, wherein when the battery-powered device is installed in the dishwasher, the conductivity sensor is configured to measure the conductivity of the cleaning solution and provide the measured conductivity value to the control unit, which is configured to process the conductivity value and generate a signal to indicate that a solid detergent block must be replenished in the dispenser if the measured conductivity value falls below a preset threshold, the signal being displayed independently of the dishwasher.

[0019] This application provides a system for distributing a detergent solution generated from a solid detergent into a dishwasher, the system being able to be installed in the dishwasher and allowing each load of solid detergent to last for multiple cleaning cycles. The system according to the present invention includes an add-on dispenser that passively distributes the detergent solution as collected water or liquid passes through the dispenser, and an add-on device powered independently of the dishwasher to measure the conductivity of the detergent solution and generate a signal (also known as a product depletion alarm) if the conductivity is low. "Passive" or "natural" means that no additional force or energy is required to operate the dispenser or dishwasher to collect water, direct its flow to solid detergent contained in the dispenser, form a detergent solution by dissolving the solid detergent, and further distribute the detergent solution through a liquid outlet. Compared to existing examples of solid detergent dispensers, the present invention provides a dispenser that houses a solid detergent block for providing a detergent solution, while providing a substantially constant amount and concentration of detergent solution for each cleaning cycle, and is easier to produce (e.g., does not require electronic equipment or a water sprayer) and easier to use (e.g., a substantially automatic detergent dispenser where the solid detergent is loaded between multiple cleaning cycles).

[0020] As used herein, the term "liquid" refers to cleaning solution or water unless otherwise specified. The term "liquid" may also refer to rinse solution.

[0021] The system according to the present invention includes a dispenser that can be spatially and functionally retrofitted to existing dishwashers, including under-counter and hood-type dishwashers, enabling the storage of enough solid detergent blocks for several cleaning cycles and their use for generating and dispensing detergent solutions. The system provided overcomes the problem of limited space for product storage and dispenser installation within the washing chamber of the dishwasher. The dispenser can hold one or more solid detergent blocks, receive water during the washing and rinsing phases of a cleaning cycle to dissolve a portion of the solid detergent blocks with substantially uniform erosion, and continuously discharge the resulting detergent solution into the dishwasher tub (which may also be referred to as the washing chamber or cleaning chamber).

[0022] The system according to the present invention eliminates the need to add dishwasher detergent before each cleaning cycle, meaning the invention provides a longer lifespan for a single product load. It also contributes to the consistency of the concentration and amount of detergent distributed by this system. Solid detergent blocks are a safer alternative to liquid detergents. The solid block form of detergent is more concentrated than the liquid form, there is no risk of spillage, and personal protective equipment is not required. Solid detergent blocks also offer sustainability advantages such as reduced packaging and water content, as well as smaller storage space at the customer's location.

[0023] The system according to the present invention further includes a battery-powered device, which includes a control unit and a conductivity sensor that is spatially and functionally retrofittable to an existing dishwasher. As a battery-powered device, it is powered independently of the dishwasher. The battery-powered device, including the control unit and conductivity sensor, is configured to represent a retrofittable device and is intended to be placed in an existing dishwasher to measure the conductivity of the cleaning solution and generate a signal (product depletion alarm) as needed. The device monitors the conductivity of the cleaning solution, and if the conductivity falls below a preset level, the device generates a signal such as a product depletion alarm to ensure that dishes are not washed with too little detergent being dispensed, resulting in strong product performance and precisely ensured dispensing amounts that ensure both cleaning and hygienic results and food safety. The level of solid detergent required for such results is guaranteed by the product depletion alarm.

[0024] In addition, the system of the present invention ensures economically and environmentally sustainable operation and product use by avoiding overloading of products, which may occur, for example, when a user of an alternative system loads multiple small loads of household-type dishwasher tubs into the dishwasher tank, as can happen in typical state-of-the-art standard processes on the market.

[0025] As described above, the battery-powered device includes a control unit and a conductivity sensor. According to the present invention, the battery-powered device is configured to operate independently of the dishwasher. The conductivity sensor measures the conductivity of the cleaning solution. The control unit processes the conductivity value measured by the conductivity sensor, and if the measured conductivity value is below a preset threshold, the control unit generates a signal to indicate to the user that the dispenser needs to be refilled with solid detergent blocks.

[0026] The signal is displayed independently of the dishwasher. This means that the battery-powered device does not communicate with the dishwasher or any of its control units; in other words, the battery-powered device and the dishwasher do not exchange any data, information, or commands. Furthermore, the signal generated by the battery-powered device is not transmitted to the dishwasher to be displayed by the dishwasher, but is displayed by the battery-powered device, which is an independent module, for example, in the form of a light signal having a specific color (e.g., by an LED), or the signal is transmitted by the battery-powered device by wireless communication to an external device located outside the dishwasher, where it is displayed. The external device may be a mobile device such as a smartphone, or it may be a computer. If the signal is displayed by the battery-powered device itself, for example, in the form of a light signal having a specific color (e.g., by an LED), the user will notice the signal when opening the dishwasher to remove washed items and / or to load items to be washed, and will be able to replenish the solid detergent block in the dispenser's detergent chamber.

[0027] As described above, the dispenser is for dissolving solid detergent blocks and dispensing the detergent solution, and is configured to be removable and retrofittable to a dishwasher. The dispenser preferably includes a mounting mechanism that allows the dispenser to be mounted inside the dishwasher. The mounting mechanism allows the dispenser to be mounted in a location within the dishwasher without substantially affecting the dishwasher's loading capacity or interfering with the operation of the dishwasher. In a preferred embodiment, the mounting mechanism allows the dispenser to be mounted on the inner surface of the washing chamber, and more preferably, allows the dispenser to be removablely mounted on the inner surface of the washing chamber of the dishwasher. In a particularly preferred further embodiment, the mounting mechanism is configured so that the dispenser can be removablely mounted on the inner surface of the washing chamber of the dishwasher without damaging the dishwasher or its components when the dispenser is removed. This can preferably be achieved by using an adhesive, such as an adhesive strip. The use of an adhesive is particularly advantageous because the dispenser can be mounted on the inner wall of the dishwasher and can be removed again without damaging the dishwasher, for example by drilling holes for screws. In a preferred embodiment, the mounting mechanism includes a mounting plate configured to be attached to the inner surface of the dishwasher, preferably by adhesive or adhesive strips, and the dispenser is configured to be removably mounted to the mounting plate. In a further preferred embodiment, the dispenser includes a mounting mechanism configured to adjust the tilt of the dispenser. By adjusting the tilt of the dispenser, the orientation of the dispenser can be adjusted so that the bottom plane of the dispenser is tilted toward the liquid outlet. This prevents the detergent solution from being retained in the dispenser and makes it possible to empty the detergent chamber.

[0028] The removable mounting mechanism allows the dispenser to be removed from the dishwasher for cleaning, and the area behind the dispenser in the dishwasher can be removed periodically or as needed to prevent food stains and / or detergent buildup.

[0029] The dispenser is configured to collect water or liquid sprayed into the washing chamber when mounted on the inner wall of the washing chamber of a dishwasher, meaning that a portion of the water or liquid sprayed into the washing chamber during the washing and rinsing cycles is collected by the dispenser.

[0030] Furthermore, when the dispenser is mounted on the inner wall of the washing chamber of the dishwasher, it is configured to guide the collected water or liquid into a solid detergent block contained within the dispenser, thereby guiding a portion of the solid detergent block to dissolve and form a detergent solution, and to enable the continuous discharge of all of the detergent solution once it has formed. This means that the dispenser discharges the detergent solution as soon as it is formed, without retaining or holding the detergent solution within the dispenser. In other words, the dispenser allows the collected water and detergent solution to pass freely from the detergent chamber to the liquid outlet without obstruction and without forming a liquid surface within the dispenser. The dispenser enables the continuous discharge of all of the formed detergent solution immediately after its formation in order to achieve emptying the detergent chamber with respect to the contents of the detergent solution. In a preferred embodiment, the dispenser is mounted in the dishwasher such that the bottom plane of the dispenser is inclined toward the liquid outlet in order to avoid retaining the detergent solution within the dispenser and to achieve emptying the detergent chamber with respect to the contents of the detergent solution. The advantage of this configuration is that it prevents swelling of the solid detergent block, which could cause blockage or damage to the dispenser. A further advantage is that the solid detergent block does not dissolve during periods when the dishwasher is not in operation.

[0031] As outlined above, the dispenser is configured to store solid detergent blocks in an amount sufficient to provide detergent solution for at least 100 cleaning cycles in a 90-second dishwasher washing program without replenishing the solid detergent blocks. In a particularly preferred embodiment, each of the solid detergent blocks contains a detergent and a rinse agent.

[0032] In a further preferred embodiment, the liquid inlet of the dispenser provides a clear opening space, and the dispenser is configured such that all collected water or liquid entering the dispenser enters the dispenser through the liquid inlet, and the liquid inlet is preferably designed as a replaceable element. Preferably designed as a replaceable element, and more preferably as a replaceable perforated plate, the clear opening space of the liquid inlet (forming the sole liquid inlet of the dispenser when ready for operation) is the "collected water or liquid," which defines the amount of water or liquid entering the dispenser and thereby defines the amount of solid detergent to be dissolved within a given period of time. A particular advantage is that the liquid inlet is replaceable with other liquid inlets having different clear opening spaces, which is useful to accommodate user needs, such as the hardness of the water where the dishwasher operates. That is, the higher the degree of water hardness, the more detergent solution must be produced within a given time limit, which means that more water or liquid needs to be collected by the dispenser, which is achieved by a larger clear opening space compared to the case of low water hardness. In a more preferred embodiment, the liquid inlet is substantially flat, located on the upper side of the dispenser, and inclined to prevent and / or to make it easier to remove dirt. In a particularly preferred embodiment, the liquid inlet is designed as a substantially flat, replaceable perforated plate located on the upper side of the dispenser and inclined.

[0033] In a particularly preferred embodiment, the dispenser houses a solid detergent block having a total weight of 400g to 600g and is preferably designed as a replaceable element (e.g., a replaceable perforated plate) 0.2cm from the liquid inlet. 2 ~3.0cm 2 Preferably 0.5 cm 2 ~2.0cm 2 It is configured to provide an effective opening space. Such a dispenser is configured to operate in a dishwasher that is configured to spray about 300-400 liters / minute of water or liquid in the washing chamber during the washing cycle, in order to allow the dispenser to generate a sufficient detergent solution.

[0034] In another preferred embodiment, the dispenser includes a liquid inlet, a pre-chamber, a detergent chamber, and a liquid outlet, fluidly connected to each other in this order, and the dispenser is configured to pass all of the collected water or liquid from the liquid inlet to the pre-chamber, from the pre-chamber to the detergent chamber to form a detergent solution by dissolving a portion of a solid detergent block, and then pass the detergent solution from the detergent chamber to the liquid outlet. As outlined above, the dispenser is configured to allow for the continuous discharge of all of the formed detergent solution once it has been formed, meaning that the dispenser discharges the detergent solution as soon as it is formed, without retaining or holding the detergent solution within the dispenser. Thus, the dispenser allows the collected water and detergent solution to pass freely from the detergent chamber to the liquid outlet without obstruction and without forming a liquid surface within the dispenser. The dispenser allows for the continuous discharge of all of the formed detergent solution in order to achieve emptying the detergent chamber with respect to the contents of the detergent solution. In a preferred embodiment, the liquid inlet of the dispenser is designed as a replaceable element, located above the pre-chamber, and more preferably as a replaceable perforated plate.

[0035] In a more preferred embodiment, the detergent chamber includes a detergent opening on the upper side for introducing a solid detergent block and a lid for closing the detergent opening, the lid sealing the detergent opening when closed. The advantage is that although the only opening for the inflow of collected water or liquid is through a liquid inlet, this limits and defines the amount of water or liquid entering the dispenser over a given period of time, thus preventing the inflow of liquid sprayed into the washing chamber through the detergent opening for the solid detergent block.

[0036] In a more preferred embodiment, the pre-chamber is positioned adjacent to the detergent chamber and separated from the detergent chamber by a partition wall that leaves fluid communication between the pre-chamber and the detergent chamber at the bottom. This configuration allows for a defined guiding of the collected water or liquid within the dispenser.

[0037] In another preferred embodiment, the detergent chamber is divided into two or more compartments by partitions that leave fluid communication between adjacent compartments at the bottom. Preferably, three compartments are arranged. Each compartment is configured to accommodate one solid detergent block. The advantage of this is that it prevents the solid detergent blocks from being pushed against or blocked by each other.

[0038] In another preferred embodiment, the dispenser further includes an additional partition between the liquid outlet and the adjacent detergent chamber (i.e., the adjacent upstream section of the detergent chamber), leaving fluid communication between the detergent chamber and the liquid outlet at the bottom. The advantage of this is that the additional partition upstream of the liquid outlet functions as a vapor barrier. In the absence of such an additional partition or vapor barrier, vapor may enter the liquid outlet and come into contact with the solid detergent block, which can result in undesirable wetting of the solid detergent. The presence of such an additional partition or vapor barrier allows vapor entering the liquid outlet to condense at this additional partition, preventing the vapor from coming into contact with the solid detergent block.

[0039] The dispenser preferably has a flat cartridge form having a rear wall, front wall, left wall, right wall, top wall, or top and bottom walls. The top preferably includes an opening for introducing a solid detergent block and a liquid inlet, which can be closed by a lid. The dispenser preferably includes a mounting mechanism in the rear wall. In its simplest form, the mounting mechanism is an adhesive or adhesive strip that attaches the rear wall of the dispenser to the inner wall of the dishwasher. Furthermore, the liquid outlet is preferably located at the lowest point of one of the side walls, front wall, or rear wall. More preferably, the liquid outlet is located at the lowest point of one of the side walls.

[0040] In a particularly preferred embodiment of the system, the dispenser includes a front wall, and at least a portion of the front wall covering the detergent chamber is transparent so that the user can visually inspect the solid detergent contents inside the dispenser.

[0041] Each solid detergent block is a solid detergent in the form of a solid block. A solid detergent is a water-soluble chemical in the form of a solid block that can be used to clean and / or disinfect objects being washed in a dishwasher. Typically, a solid block has the shape of a rectangular tablet. If necessary, the rectangular tablet may be made to have rounded edges and / or corners. A solid detergent may include a washing agent (which may also be called a cleaning agent or detergent), a washing agent and rinser (which may also be called a rinsing aid), or a washing agent, a rinser, and a disinfectant. In a preferred embodiment, the solid detergent includes a washing agent, a rinser, and a disinfectant (which may also be called a “three-in-one” detergent). In a particularly preferred embodiment, the solid detergent includes two agents, namely a washing agent and a rinser, and does not include a sanitizing agent (which may also be called a “two-in-one” detergent). Preferably, the rinse solution is fresh water, and the rinsing effect is achieved by the rinsing agent contained in the "two-in-one" detergent, which is present on the items being washed when rinsing begins for the duration of the wash cycle. As a result, since fresh water is used as the rinse solution, the dishwasher requires only one tank for the washing solution.

[0042] In this application, “dishwasher” is also called an article washing machine or article washing machine and includes all types of washing machines that can use detergent for cleaning and / or disinfection purposes. Examples include under-counter or hood-type dishwashers for washing dishes, plates, pots and pans, cutlery, glasses, kitchenware, pots, trays, etc. Examples of commercially available dishwashing appliances can also be used in this subject matter. A dishwasher includes a washing chamber formed by the inner wall and door of the dishwasher. In the example of an under-counter kitchen dishwasher, the door rotates up to approximately 90 degrees around a horizontal axis to switch between a fully closed and fully open position. The door has an inner and an outer side, both of which are substantially vertical when the door is fully closed and substantially horizontal when the door is fully open.

[0043] In this application, a “cleaning cycle” includes one or more of a wash period, a rinse period, and a drying period, depending on the settings made by the user of the dishwasher. In a preferred embodiment, the dishwasher is configured to perform a cleaning cycle consisting of a wash period and a rinse period, i.e., the cleaning cycle does not include a drying cycle. Therefore, in a preferred embodiment, the dishwasher does not provide means for drying the cleaning items. After cleaning, the cleaning items dry essentially outside the dishwasher, as drying can only occur by the energy absorbed by the cleaning items from the hot rinse water.

[0044] A dishwasher equipped with the system according to the present invention is preferably configured to provide selectable programs with different cleaning cycle durations. In particular, the dishwasher is configured to provide a program in which the selectable duration of each cleaning cycle is 60 to 300 seconds per cleaning cycle, and each cleaning cycle includes a washing period and a rinsing period, with a temperature in the range of 50°C to 85°C. Furthermore, it is preferable that the dishwasher is configured so that 300 to 400 liters / minute of liquid are sprayed during the washing period and 2 to 3 liters / rinse cycle of water are sprayed during the rinsing period.

[0045] Therefore, when referring to a dispenser according to the present invention or a system including such a dispenser, configured to contain a sufficient amount of solid detergent block to provide detergent solution for at least 100 cleaning cycles in a 90-second dishwasher cleaning program, the dishwasher is configured to provide a program in which, when the dispenser is mounted inside the dishwasher (preferably on the inner wall of the washing chamber of the dishwasher), the selectable duration of each cleaning cycle, including a wash period and a rinse period, is between 60 and 300 seconds per cleaning cycle.

[0046] In another preferred embodiment, the dishwasher to which the system according to the present invention is to be installed is preferably configured to provide a program having a cleaning cycle consisting of a washing period and a rinsing period.

[0047] In a more preferred embodiment, the dishwasher to be equipped with the system according to the present invention includes a heating system for bringing the washing solution and rinse water to a preset temperature, as well as a temperature sensor and a control unit for controlling the temperature. More preferably, the dishwasher does not include any further sensors, except for the temperature sensor and any aftermarket conductivity sensors. That is, the dishwasher preferably does not include a turbidity sensor (typically used to determine the turbidity of the washing solution), a position sensor (typically used to determine the rotation of the spray arm), a sensor for determining the pH of the washing solution, or a sensor for determining the hardness of tap water.

[0048] A typical cleaning procedure using a dishwasher is as follows: The door is opened at least once between two consecutive cleaning cycles to allow loading of dishes and / or other objects to be washed and unloading of washed dishes and / or other objects. "Cleaning" can include cleaning only, disinfecting only, or cleaning and disinfecting, depending, for example, whether the solid detergent block is capable of cleaning only, disinfecting only, or cleaning and disinfecting. "Washing period" includes a period or mode of operation in which a cleaning mixture formed by water and detergent is intended to be applied to dishes and / or other objects. "Rinsing period" includes a period or mode of operation in which water, or water plus a chemical rinsing aid and / or a chemical disinfectant, is intended to be applied to dishes and / or other objects. "Rinsing period" refers to a period or mode of operation in which water is intended to be applied to dishes and / or other objects. Preferably, since the solid detergent contains two agents, a detergent and a rinse agent ("two-in-one" detergent), the rinse solution is preferably fresh water. Here, the rinsing effect is achieved by the rinsing agent contained in the "two-in-one" detergent, which comes into contact with the items being cleaned during the washing period. The "two-in-one" detergent containing the detergent and rinsing agent is used during the washing period, and therefore the rinsing agent is present on the items to be cleaned when rinsing begins.

[0049] Some dishwashers (e.g., commercially available dishwashers) may include a rinsing period primarily for disinfection by application and / or treatment of heat and / or chemicals. A “drying period” includes a period or mode of operation intended to dry washed dishes and / or other objects by airflow and / or heat without the application of additional water and / or detergent. Dishwashers typically allow the user to choose whether or not to include a drying period in the cleaning cycle, as the user can either open the dishwasher door to allow washed and rinsed dishes to air dry or move the washed and rinsed dishes to another location to dry. Preferably, the dishwasher does not have a drying mechanism.

[0050] [Dispenser] First embodiment of a dispenser As stated above, this disclosure also relates to a dispenser for distributing a detergent solution from a solid detergent into a dishwasher, and said dispenser, - To contain a sufficient amount of solid detergent block to provide detergent solution for at least 10 cleaning cycles, - It can be easily and retrofitted to a dishwasher. When it is detachably mounted on the inner wall of the washing chamber of a dishwasher, -Collecting water or liquid sprayed into the cleaning chamber through the liquid inlet, - The collected water or liquid is guided into a solid detergent block contained in a dispenser, thereby causing a portion of the solid detergent block to dissolve and a detergent solution to be formed. - Once the detergent solution is formed, it is configured to allow for the continuous release of all of the detergent solution.

[0051] As used herein, "to enable continuous discharge of all detergent solution once formed" means that the dispenser discharges the detergent solution as soon as it is formed, without retaining or holding any detergent solution within the dispenser. In other words, the dispenser allows the collected water and detergent solution to pass freely from the detergent chamber to the liquid outlet without obstruction and without forming a liquid surface within the dispenser. The dispenser allows for the continuous discharge of all of the formed detergent solution immediately after its formation in order to achieve emptying the detergent chamber with respect to the contents of the detergent solution.

[0052] The liquid inlet of the dispenser provides an effective opening space, and the dispenser is preferably configured so that all of the collected water or liquid entering the dispenser enters the dispenser through the liquid inlet. In a particularly preferred embodiment, the liquid inlet is designed as a replaceable element. This is advantageous because the liquid inlet can be replaced with other liquid inlets having different effective opening spaces, which is useful to adapt to user needs, for example, by taking into account the hardness of the water in the location where the dishwasher operates.

[0053] In a preferred embodiment, the dispenser includes a liquid inlet, a pre-chamber, a detergent chamber, and a liquid outlet, fluidly connected to each other in this order, and the dispenser is configured to pass all of the collected water or liquid from the liquid inlet to the pre-chamber, from the pre-chamber to the detergent chamber to dissolve a portion of the solid detergent block and form a detergent solution, and to pass the detergent solution from the detergent chamber to the liquid outlet. Preferably, the liquid inlet of the dispenser is located above the pre-chamber and is designed as a replaceable element.

[0054] In a more preferred embodiment, the detergent chamber further includes a detergent opening and a lid on the upper side for introducing a solid detergent block, the lid sealing the opening for introducing the solid detergent block when closed.

[0055] More preferably, the pre-chamber is located adjacent to the detergent chamber and separated from the detergent chamber by a partition wall that leaves fluid communication between the pre-chamber and the detergent chamber at the bottom. In another preferred embodiment, the detergent chamber is divided into two or more compartments by partition walls that leave fluid communication between adjacent compartments at the bottom.

[0056] In another preferred embodiment, the dispenser may further include an additional partition between the liquid outlet and the adjacent detergent chamber (i.e., the adjacent upstream section of the detergent chamber), leaving fluid communication between the detergent chamber and the liquid outlet at the bottom at the bottom, and the additional partition functions as a vapor barrier.

[0057] Preferably, the dispenser contains a solid detergent block having a total weight of 400g to 600g, and 0.2cm 2 ~3.0cm 2 Preferably 0.5 cm 2 ~2.0cm 2 It is configured to provide an effective opening space for the liquid inlet. With this configuration, the dispenser is configured to operate in a dishwasher that is configured to spray approximately 300-400 liters / minute of water or liquid in the washing chamber during the washing cycle, allowing the dispenser to produce a sufficient detergent solution.

[0058] In another preferred embodiment, the dispenser includes a mounting mechanism that allows the dispenser to be installed in a dishwasher from the inside, the mounting mechanism includes a mounting plate configured to be attached to the inner surface of the dishwasher, preferably by adhesive or adhesive strips, and the dispenser is configured to be removably attached to the mounting plate.

[0059] More preferably, the dispenser includes a mounting mechanism configured to adjust the inclination of the dispenser. This function of adjusting the inclination of the dispenser in the dishwasher allows the orientation of the dispenser to be adjusted so that the bottom plane of the dispenser is inclined toward the liquid outlet. This retains the detergent solution within the dispenser and prevents the liquid level of the detergent solution formed within the dispenser from rising, thereby achieving emptying of the detergent chamber.

[0060] As described above, the dispenser preferably has a flat cartridge form having a rear wall, front wall, left wall, right wall, top wall, or top and bottom walls. The top preferably includes an opening for introducing a solid detergent block which can be closed by a lid, and a liquid inlet. The dispenser preferably includes a mounting mechanism in the rear wall. In its simplest form, the mounting mechanism is an adhesive or adhesive strip that attaches the rear wall of the dispenser to the inner wall of the dishwasher. Furthermore, the liquid outlet is preferably located at the lowest point of one of the side walls, front wall, or rear wall. More preferably, the liquid outlet is located at the lowest point of one of the side walls.

[0061] In a particularly preferred embodiment of the dispenser, and in a particularly preferred embodiment of the system, the dispenser includes a front wall, and at least a portion of the front wall covering the detergent chamber is transparent so that the user can visually inspect the solid detergent contents inside the dispenser.

[0062] Second embodiment of the dispenser The disclosure further provides, in an alternative embodiment (second embodiment), a dispenser for distributing a detergent solution from a solid detergent into a dishwasher, the dispenser comprising a liquid inlet, a detergent chamber, and a liquid outlet in fluid communication with each other in that order, the dispenser being configured to allow all the liquid collected by the dispenser to pass from the liquid inlet to the detergent chamber to dissolve a portion of the solid detergent block and form a detergent solution, and to allow the detergent solution to pass from the detergent chamber to the liquid outlet, thereby enabling the continuous discharge of all the detergent solution once formed.

[0063] As stated above, "to enable continuous discharge of all detergent solution once formed" means that the dispenser discharges the detergent solution as soon as it is formed, without retaining or holding any detergent solution within the dispenser. In other words, the dispenser allows the collected water and detergent solution to pass freely from the detergent chamber to the liquid outlet without obstruction and without forming a liquid surface within the dispenser. The dispenser allows for the continuous discharge of all of the formed detergent solution immediately after its formation in order to achieve emptying the detergent chamber with respect to the contents of the detergent solution.

[0064] In a preferred embodiment, the liquid inlet is designed as an interchangeable element for changing the effective opening space of the liquid inlet.

[0065] In a preferred embodiment, one or more additional interchangeable elements are provided, intended to be mounted on the dispenser to form a liquid inlet, each of which provides a specific effective opening space that is different from that of the first interchangeable element.

[0066] The replaceable element forming the liquid inlet defines the amount of solid detergent dissolved within a given period. The advantage of providing a replaceable liquid inlet, i.e., a replaceable element, is that by replacing the replaceable element with another element having a different effective opening space, the dispenser can be adapted to the user's needs, for example, the water hardness at the location where the dishwasher operates.

[0067] More preferably, the dispenser includes an additional chamber adjacent to the detergent chamber, and the liquid inlet of the dispenser is disposed on the upper side of the dispenser and provides an opening to the additional chamber. Preferably, the additional chamber adjacent to the detergent chamber is separated from the detergent chamber by a partition that leaves a fluid communication between the additional chamber and the detergent chamber at the bottom.

[0068] Preferably, the liquid inlet of the dispenser provides an effective opening space, and the dispenser is configured such that all of the collected water or liquid entering the dispenser enters the dispenser through the liquid inlet.

[0069] In a particularly preferred embodiment, the dispenser accommodates a solid detergent block having a total weight of 400 g to 600 g and is configured to provide an effective opening space for the liquid inlet of 0.2 cm 2 to 3.0 cm 2 , preferably 0.5 cm 2 to 2.0 cm 2 . This is achieved by replacing the replaceable element forming the liquid inlet with another replaceable element having an effective opening space different from the first one. Such a dispenser is configured to operate within a dishwasher configured to spray water or liquid at about 300 to 400 liters per minute during a washing cycle within the washing chamber to enable the dispenser to generate a sufficient amount of detergent solution.

[0070] In another preferred embodiment, the detergent chamber further includes a detergent opening and a lid for introducing a solid detergent block on the upper side, the lid sealing the opening for introducing the solid detergent block when closed.

[0071] In another preferred embodiment, the detergent chamber is divided into two or more compartments by partitions that leave fluid communication between adjacent compartments at the bottom.

[0072] In a more preferred embodiment, the dispenser further includes an additional partition between the liquid outlet and an adjacent detergent chamber, leaving a fluid communication between the detergent chamber and the liquid outlet at the bottom, the additional partition serving as a vapor barrier.

[0073] In another preferred embodiment, the dispenser includes a mounting mechanism that allows the dispenser to be installed from the inside into a dishwasher, the mounting mechanism including a mounting plate configured to be mounted on the inner surface of the dishwasher, and the dispenser is configured to be removably mounted on the mounting plate.

[0074] Preferably, the dispenser includes a mounting mechanism that includes a device for adjusting the tilt of the dispenser when it is placed inside a dishwasher.

[0075] As described above, the dispenser preferably has a flat cartridge form having a rear wall, front wall, left wall, right wall, top wall, or top and bottom walls. The top preferably includes an opening for introducing a solid detergent block which can be closed by a lid, and a liquid inlet. The dispenser preferably includes a mounting mechanism in the rear wall. In its simplest form, the mounting mechanism is an adhesive or adhesive strip that attaches the rear wall of the dispenser to the inner wall of the dishwasher. Furthermore, the liquid outlet is preferably located at the lowest point of one of the side walls, front wall, or rear wall. More preferably, the liquid outlet is located at the lowest point of one of the side walls.

[0076] In a more preferred embodiment of the dispenser, the dispenser includes a front wall, and at least a portion of the front wall covering the detergent chamber is transparent so that the user can visually inspect the solid detergent contents inside the dispenser.

[0077] In a particularly preferred embodiment, the dispenser is configured to house a solid detergent block in an amount sufficient to provide a detergent solution for at least 10 cleaning cycles, to be removable and retrofittable to a dishwasher, and when removablely mounted on the inner wall of the dishwasher's washing chamber, to collect water or liquid sprayed into the washing chamber by a liquid inlet, to guide the collected water or liquid to the solid detergent block housed in the dispenser, thereby guiding a portion of the solid detergent block to dissolve and form a detergent solution, and, once the detergent solution is formed, to enable the continuous discharge of the entire detergent solution.

[0078] [Set including dispenser] Furthermore, this disclosure states that A dispenser for distributing a detergent solution from solid detergent into a dishwasher, comprising a liquid inlet, a detergent chamber, and a liquid outlet, configured to allow all the liquid collected by the dispenser to pass through the liquid inlet to the detergent chamber to dissolve a portion of the solid detergent block and form a detergent solution, and to enable continuous discharge of detergent through the liquid outlet, wherein the liquid inlet is designed as a replaceable element, and the dispenser, A set is provided, comprising a first replaceable element intended to be mounted on a dispenser to form a liquid inlet, and providing a specific effective opening space.

[0079] In a preferred embodiment, the set includes one or more additional interchangeable elements intended to be mounted on the dispenser to form a liquid inlet, each of which provides a specific effective opening space that is different from that of the first interchangeable element and distinct from each other.

[0080] In a more preferred embodiment, the dispenser is configured to accommodate a solid detergent block having a total weight of 400g to 600g, and by replacing interchangeable elements with others, the effective opening space of the liquid inlet is 0.2cm. 2 ~3.0cm 2 Preferably 0.5 cm 2 ~2.0cm 2 Such dispensers are configured to operate in a dishwasher that is configured to spray approximately 300-400 liters / minute of water or liquid per minute within the washing chamber during a washing cycle, in order to allow the dispenser to produce a sufficient detergent solution.

[0081] As described above, the dispenser is configured such that all of the collected water or liquid entering the dispenser enters the dispenser through the liquid inlet. In this embodiment, the liquid inlet is designed as a replaceable element. Preferably designed as a replaceable element, and more preferably as a replaceable perforated plate, the effective opening space of the liquid inlet (forming the dispenser's sole liquid inlet when ready for operation) defines the amount of water or liquid entering the dispenser, which is the “collected water or liquid”. Thus, the replaceable element defines the amount of solid detergent to be dissolved within a given period. The advantage of providing a replaceable liquid inlet, i.e., a replaceable element, is that the dispenser can be adapted to the user’s needs, for example, the water hardness in the location where the dishwasher operates, by replacing the replaceable element with another element having a different effective opening space. In a particularly preferred embodiment, the liquid inlet is designed as a substantially flat, replaceable perforated plate located on the upper side of the dispenser and inclined.

[0082] In a particularly preferred embodiment of the set, the dispenser is configured to allow for the continuous discharge of all detergent solution once it has formed, meaning that the dispenser discharges the detergent solution as soon as it has formed, without retaining or holding any detergent solution within the dispenser. That is, the dispenser allows the collected water and detergent solution to pass freely from the detergent chamber to the liquid outlet without obstruction and without forming a liquid surface within the dispenser. The dispenser allows for the continuous discharge of all of the formed detergent solution immediately after its formation in order to achieve emptying the detergent chamber with respect to the contents of the detergent solution.

[0083] As described above, the dispenser preferably has a flat cartridge form having a rear wall, front wall, left wall, right wall, top wall, or top and bottom walls. The top preferably includes an opening for introducing a solid detergent block which can be closed by a lid, and a liquid inlet. The dispenser preferably includes a mounting mechanism in the rear wall. In its simplest form, the mounting mechanism is an adhesive or adhesive strip that attaches the rear wall of the dispenser to the inner wall of the dishwasher. Furthermore, the liquid outlet is preferably located at the lowest point of one of the side walls, front wall, or rear wall. More preferably, the liquid outlet is located at the lowest point of one of the side walls.

[0084] In another preferred embodiment of the set, the dispenser includes a front wall, and at least a portion of the front wall covering the detergent chamber is transparent so that the user can visually inspect the solid detergent contents inside the dispenser.

[0085] [method] The present invention further provides a method for dispensing a detergent solution from a dispenser in a dishwasher capable of performing each cleaning cycle, including a washing period and a rinsing period, the method being: i. Placing one or more solid detergent blocks containing detergent and rinse agents in an amount sufficient to provide detergent solution for at least 10 cleaning cycles within the detergent chamber of the dispenser, ii. Collecting a portion of the water or liquid sprayed into the dishwasher during the washing and rinsing cycle, and using the collected water to dissolve a portion of the solid detergent to form a detergent solution in the detergent chamber of the dispenser, iii. Once the detergent solution is formed, the entire detergent solution is continuously released from the dispenser, iv. Measuring the conductivity of the washing solution using a conductivity sensor of a battery-powered device placed inside the dishwasher, v. Provide the measured conductivity value to the control unit of the battery-powered device for processing. vi. The control unit generates a signal to indicate that a solid detergent block must be replenished in the dispenser if the conductivity value falls below a preset threshold, and displays the signal independently of the dishwasher.

[0086] According to the method of the present invention, a detergent solution can be distributed from each load of solid detergent contained in a dispenser over multiple cleaning cycles. The detergent solution is prepared by the dispenser by passively collecting water or liquid sprayed into the dishwasher, passing it through the dispenser, and bringing it into contact with solid detergent that is dissolved in substantially uniform erosion. "Passive" means that no additional force or energy is required to operate the dispenser or dishwasher to collect water, direct its flow towards the solid detergent contained in the dispenser, dissolve the solid detergent to form a detergent solution, and then distribute the detergent solution through the liquid outlet. The detergent solution thus produced is continuously released into the washing chamber of the dishwasher, thereby providing a substantially consistent amount and concentration of detergent solution for each cleaning cycle over multiple cleaning cycles. Therefore, according to the method of the present invention, it is not necessary to add dishwasher detergent before each cleaning cycle.

[0087] Importantly, according to the method of the present invention, all (or substantially all) of the detergent solution is released from the dispenser as soon as it is formed. This means that, compared to existing examples of solid detergent dispensers, the detergent solution is not retained or held within the dispenser, and a free passage for the formed detergent solution is provided within the dispenser without obstruction and without forming a liquid surface within the dispenser. This makes it possible to continuously release the formed detergent solution immediately after its formation in order to achieve emptying the detergent chamber with respect to the contents of the detergent solution. This continuous release of the detergent solution is advantageous because it prevents swelling of the solid detergent block, which could otherwise cause blockage or damage to the dispenser. The method of the present invention also ensures economically and environmentally sustainable operation and product use by avoiding, for example, overfilling of the product, which would occur if a user simply placed multiple small loads of household dishwasher tubs into the dishwasher tank.

[0088] According to the method of the present invention, the conductivity of the cleaning solution is measured by a conductivity sensor, and the respective data is processed. When the conductivity value falls below a predetermined threshold, a signal is generated, which is displayed independently of the dishwasher. This signal indicates to the user that solid detergent must be replenished in the dispenser (product depletion alarm). Such a product depletion alarm ensures that washing is not performed with too low a level of detergent being dispensed, resulting in strong product performance and precisely controlled dispensing amounts that ensure both cleaning and hygiene results and food safety. These steps are performed by an independent device powered independently of the dishwasher. The signal may be displayed by a battery-powered device, preferably in the form of an optical signal. Alternatively, the signal may be transmitted wirelessly by a battery-powered device to an external device located outside the dishwasher for display by an external device. The advantage of using independent, retrofittable devices such as a dispenser and battery-powered device, including a control unit and conductivity sensor, is that when the method of the present invention is performed, there is no need to replace the technically relatively simple dishwasher, and such an existing dishwasher can be upgraded using such an independent device.

[0089] In a preferred embodiment, the method includes the following steps a to c before steps i to vi, i.e., a. A step of selecting and installing a specific effective opening space for the liquid inlet of the dispenser, b. Steps to add a removable dispenser inside the dishwasher, c. The step of retrofitting a battery-powered device, including a control unit and a conductivity sensor, into the dishwasher in a removable manner, and the steps in any order.

[0090] The effective opening space of the liquid inlet determines the amount of water or liquid that enters the dispenser, and thereby determines the amount of solid detergent that is dissolved within a given period of time. The option to choose from different liquid inlets (since liquid inlets are interchangeable) and different effective opening spaces is advantageous because the inflow of sprayed water or liquid into the dispenser can be adapted to the user's needs, for example, by considering the hardness of the water where the dishwasher operates. The higher the degree of water hardness, the more detergent solution must be produced within a given time limit, which means that more water or liquid needs to be collected by the dispenser, which is achieved by a larger effective opening space compared to the case of low water hardness. Therefore, in a preferred method, the liquid inlet is designed as an interchangeable element, and this method further includes the step of changing a particular effective opening space of the liquid inlet by replacing the interchangeable element with another interchangeable element having a different specific effective opening space.

[0091] The present invention is illustrated in more detail in the following embodiments.

[0092] Figure 1 is a perspective view of one embodiment of a dispenser 1 according to the system of the present invention, which is placed inside a dishwasher. The system according to the present invention includes a dispenser 1 for dispensing a detergent solution and a battery-powered device for measuring the conductivity of the cleaning solution. An example of this system is described below with reference to Figure 5.

[0093] Dispenser 1 is generally designed in the form of a flat cartridge having a rear wall, front wall, left wall, right wall, top wall (or upper side), and bottom wall. The upper side includes an opening 9 for introducing a solid detergent block, which can be closed by a lid 8. The upper side of dispenser 1 also includes a liquid inlet 2. In the rear wall, dispenser 1 includes a mounting mechanism for attaching it to the inner wall of a dishwasher. A liquid outlet 5 is located at the lowest point of one of the side walls 10.

[0094] Dispenser 1 includes a transparent window on its front wall, allowing the user to visually inspect the inside of dispenser 1 and thereby visually check the amount of solid detergent present inside dispenser 1.

[0095] The dispenser 1 shown in the figure further includes a liquid inlet 2, a pre-chamber 3, a detergent chamber 4, a liquid outlet 5, partitions 6 for subdividing the detergent chamber 4 into several compartments, each holding a solid detergent block (not shown), and additional partitions 7 (not shown in Figure 1) that function as a vapor barrier. The pre-chamber 3 is separated from adjacent compartments of the detergent chamber 4 by partitions. All partitions provide passages at the bottom, so that all compartments of the pre-chamber 3 and detergent chamber 4 are in fluid communication with each other, and also with the liquid outlet 5 located at the bottom of the side wall of the dispenser 1 opposite the pre-chamber 3.

[0096] Here, the detergent chamber 4, which is divided into three sections, can accommodate solid detergent blocks. The liquid inlet 2 is in fluid communication with the detergent chamber 4 via the pre-chamber 3 and can collect water sprayed into the dishwasher during the washing and rinsing cycles. The collected water flows into the detergent pre-chamber 3 and then into the detergent chamber 4, where a detergent solution can be formed by dissolving a portion of the solid detergent. The liquid outlet 5, located on the left wall of the dispenser 1, is in fluid communication with the detergent chamber 4 and continuously discharges the detergent solution from the detergent chamber 4 as soon as the detergent solution is formed. The dispenser 1 is configured to perform its functions automatically and is not motorized.

[0097] The dispenser 1 is advantageously mounted on the inner wall of the dishwasher's washing chamber such that its bottom plane is inclined, for example, by 1-3° toward the liquid outlet 5. This allows for the continuous discharge of all the formed detergent solution, thereby emptying the detergent chamber 4 and the dispenser 1 in general with respect to the contents of the detergent solution, preventing the detergent solution from being retained in the dispenser 1, and achieving the emptying of the detergent chamber 4 through the liquid outlet 5.

[0098] The detergent chamber 4 can accommodate a solid detergent block. The detergent chamber 4 includes a detergent opening on its upper side for receiving the solid detergent block (the detergent opening is not visible in Figure 1). The dispenser 1 further includes a lid 8 for closing the detergent opening and holding the received block. When closed, the lid 8 seals the detergent opening, thereby preventing the inflow of liquid sprayed into the washing chamber through the detergent opening. The only opening for introducing the collected water or liquid into the dispenser 1 is through the liquid inlet 2.

[0099] The liquid inlet 2 is positioned and oriented to passively or naturally collect the water sprayed into the dishwasher during the wash and rinse cycles (or any period during which water is sprayed into the dishwasher), and to allow the collected water to flow into the detergent chamber 4 to form a detergent solution by dissolving a portion of the solid detergent block. Being “passive” or “natural” means that no additional force or energy is required to operate the dispenser or dishwasher to collect the water, guide its flow into the detergent chamber 4, form a detergent solution by dissolving the solid detergent, and then distribute the detergent solution through the liquid outlet 5.

[0100] The liquid inlet 2 is required to partially expose the solid detergent placed in the detergent chamber 4 to the water sprayed into the dishwasher. The liquid inlet 2 is the only opening for liquid entry, and as a result, all the collected water or liquid entering the dispenser enters the dispenser through the liquid inlet 2.

[0101] Figure 2 is another perspective view from the right side of the dispenser shown in Figure 1. Dispenser 1 includes a liquid inlet 2, a pre-chamber 3, a detergent chamber 4, a liquid outlet 5, and a partition wall 6 for subdividing the detergent chamber 4 into several compartments, each holding a solid detergent block (not shown), and an additional partition wall 7 that functions as a vapor barrier. The liquid outlet 5 is not visible in the perspective view shown in Figure 2 because a frame on the front wall of dispenser 1 (for holding a transparent window) obstructs the view to the liquid outlet 5.

[0102] As described above, the liquid inlet 2 can collect water sprayed into the dishwasher. The collected water enters the pre-chamber 3 and is sent to the detergent chamber 4. Preferably, the liquid inlet 2 is formed by a replaceable perforated plate 2, as shown in the figure. The effective opening space of the replaceable perforated plate 2 defines the amount of water or liquid entering the dispenser 1, so that all of the collected water or liquid entering the dispenser enters the dispenser through the liquid inlet 2. The replaceable element or perforated plate forming the liquid inlet 2 provides a specific effective opening space. The replaceable element or perforated plate forming the liquid inlet 2 may be replaced by different elements or perforated plates having different effective opening spaces to adapt the inflow of liquid to the dispenser 1 to suit user needs, such as the hardness of the water in the area where the dishwasher is operated. In the embodiment shown in the figure, the perforated plate 2 is inclined to prevent the accumulation of dirt.

[0103] As described, the detergent chamber 4 is configured to house a solid detergent block. The detergent chamber 4 includes a detergent opening 9 on the upper side of the dispenser 1 for introducing the solid detergent block into the detergent chamber 4. Furthermore, a lid (not shown in Figure 2) is positioned to close the detergent opening 9.

[0104] Figure 3 is a further diagram of a dispenser according to one embodiment of the present invention. The diagram below is a top view of dispenser 1 shown in Figures 1 and 2. The top of the dispenser is mainly covered by a lid that closes the detergent chamber. Furthermore, the diagram shows a liquid inlet 2 designed as a perforated plate.

[0105] The upper drawing of the figure is a cross-sectional view of dispenser 1 along line AA shown in the lower drawing. Dispenser 1 includes a liquid inlet 2 designed as a perforated plate, a pre-chamber 3, and a detergent chamber 4 having three compartments, the detergent chamber 4 being divided by a partition wall 6, an additional partition wall 7, a liquid outlet 5 located on the left side wall 10, and a lid 8 covering the detergent opening.

[0106] As described above, the liquid inlet 2, designed as a perforated plate, is in fluid communication with the detergent chamber 4 via the pre-chamber 3. The liquid inlet 2 collects water that flows into the pre-chamber 3 and then into the detergent chamber 4, which contains a solid detergent block (not shown), and forms a detergent solution by dissolving a portion of the solid detergent.

[0107] The upper diagram shows that the pre-chamber 3, the detergent chamber 4 compartment, and the liquid outlet 5 are in fluid communication. Fluid communication is achieved by the partition wall between the pre-chamber 3 and the detergent chamber 4, the partition wall 6 dividing the detergent chamber 4 into compartments, and the additional partition wall 7, each leaving a flow opening at the bottom of the dispenser 1. This feature allows for the continuous discharge of the detergent solution formed in the detergent chamber 4 as soon as the detergent solution is formed. As can be seen from the diagram, the dispenser 1 discharges the detergent solution as soon as it is formed, without retaining or holding the detergent solution within the dispenser 1. In other words, the dispenser allows the collected water and detergent solution to pass freely from the detergent chamber 4 to the liquid outlet 5 located at the bottom of the side wall 10 without obstruction and without forming a liquid surface within the dispenser 1.

[0108] The embodiment of dispenser 1 shown in the figure further includes an additional partition wall 7 between the liquid outlet 5 and the adjacent upstream section of the detergent chamber 4. The purpose of the additional partition wall 7 upstream of the liquid outlet 5 is to function as a vapor barrier. Vapors that may enter the liquid outlet 5 condense at this additional partition wall 7 before reaching the solid detergent block located in the detergent chamber 4, which could result in undesirable wetting of the solid detergent. The additional partition wall 7 is positioned parallel to the side wall 10 containing the liquid outlet 5 at a short distance, thereby forming an additional narrow chamber positioned between them.

[0109] Figure 4 is a graph showing the conductivity measurement of the solid detergent concentration in the solution inside the dishwasher tank, and simultaneously visual control of the amount of solid product remaining in the dispenser.

[0110] To check the product depletion alarm, three solid detergent blocks containing two agents, a detergent, and a rinse agent, with a total weight of 525g, were filled into a dispenser placed inside an under-counter dishwasher. The dispenser used in the experiment was of the type shown in Figures 1-3. The effective opening space of the liquid inlet 2 of the dispenser was 1.0 cm. 2 Furthermore, specific sensors were placed inside the dishwasher tank to measure the conductivity of the cleaning solution. The dishwasher was started and multiple cycles were run, each containing a 70-second wash period and a 10-second rinse period, at a temperature of 60°C for the wash cycle and 83°C for the rinse cycle. During the wash period, 350 liters / minute of cleaning solution were circulated, and during the rinse period, 2-3 liters / rinse cycle of water were sprayed onto the dishes.

[0111] Since conductivity represents the concentration of solid detergent in a solution, the conductivity of the detergent solution in the dishwasher tank was measured using a specific sensor. In parallel, the amount of solid detergent block remaining in the dispenser was visually monitored. Changes in conductivity over time correlated with the increasing dissolution of the block; that is, conductivity correlated with the visual detection of block disappearance. The arrows in Figure 4 indicate the point at which the total amount of solid detergent in the dispenser became considerably low. Initially, the conductivity increased rapidly and remained constant at approximately 3.5 S / cm for about 15,000 seconds. Subsequently, the conductivity decreased to approximately 1.5 S / cm, corresponding to a total of 200 g of solid detergent remaining in the dispenser (left arrow). After further decrease, the conductivity was approximately 0.7-0.8 S / cm, corresponding to a total of 50 g of solid detergent remaining in the dispenser (right arrow) out of the total amount of solid detergent initially loaded into the dispenser (525 g) before the start of the experiment. The experiment demonstrated that the conductivity signal is an accurate measure of the solid product level within the dispenser.

[0112] These tests demonstrated that the solid detergent product is dissolved in a controlled manner by the dispenser, thereby indicating a product depletion alarm based on the same measurement principle (mediated by a battery-powered device including a control unit and conductivity sensor) that measures conductivity, when the product level in the dishwasher is too low and the solid detergent product needs to be reloaded.

[0113] The conductivity at which the alarm is triggered can be freely selected, allowing the system to remotely warn the user to reload the product before product consumption in the dispenser is complete.

[0114] Figure 5 is a block diagram of one embodiment of a system 20 according to one embodiment of the present invention, which is arranged inside a dishwasher. The system 20 includes a dispenser 1 for dispensing detergent solution and a battery-powered device 21 for measuring the conductivity of the cleaning solution.

[0115] The battery-powered device 21 includes a control unit 22 and a conductivity sensor 23. The battery-powered device 21, control unit 22, and conductivity sensor 23 according to various embodiments of the present invention are described above as “battery-powered device,” “control unit,” and “conductivity sensor,” respectively. In one embodiment, the battery-powered device 21 is configured to operate independently of the dishwasher and to be removable and retrofittable to the dishwasher. When the battery-powered device 21 is removablely attached to the dishwasher, the conductivity sensor 23 is configured to measure the conductivity of the cleaning solution and provide the measured conductivity value to the control unit 22. The control unit 22 is configured to process the conductivity value and generate a signal to indicate that a solid detergent block must be replenished in the dispenser 1 if the conductivity value falls below a preset threshold. The signal is displayed independently of the dishwasher. [Examples]
