Description

technical field

The invention relates to a dishwasher and a method for cleaning items to be cleaned. Dishwashers and methods of the type mentioned can be used, for example, in the field of commercial dishwashing technology. Thus, the invention can be used in particular in commercial single-chamber dishwashers such as program machines or also in tunnel dishwashers such as conveyor belt and/or rack conveyor dishwashers. However, other areas of use are also conceivable in principle.

Technical background

A large number of dishwashers are known from the prior art. Overall, the design of these dishwashers depends heavily on the various boundary conditions, such as the type of items to be cleaned, the soiling, the throughput or similar conditions. As an example, reference can be made to dishwashers, which, for example, in DE 10 2004 056 052 A1 is described.

Dishwashers of the type mentioned usually have at least one application device for applying at least one cleaning fluid to the items to be cleaned. For example, a nozzle system, in particular a washing system with one or more nozzles, can be provided in order to apply one or more cleaning fluids, such as liquids and/or steam, to the items to be cleaned.

Either liquid treatment agents or solid treatment agents, for example a detergent and a rinse aid, are metered into commercial dishwashers. For this purpose, the detergent and/or rinse aid can basically be filled into cartridges or pressed into blocks, used in a special dosing device or in a special dosing unit, which can also be referred to as a dissolving unit, and mixed with water, which is applied to the solids in the cartridge or being sprayed onto the block. The water can have a temperature of preferably 45° C. and can usually be taken from an on-site hot water pipe. The water supply to the dissolving unit for the solid cleaner is usually provided by a so-called mains disconnection device, which separates the on-site water network from the dosing device so that no toxic substances flow back into the water supply from the dosing device in the event of any back-sucking in the on-site network. The hot water line or a hot water connection must be provided on site in addition to the dishwasher connection.

In addition to the separate water connection, the solids dosing devices on the market also have their own control to monitor the concentration of the cleaning agent in different treatment zones and to add more if necessary. A technical control connection to the dishwasher is basically reduced to a release signal from the dishwasher and a single error signal from the dosing unit. This means that in the event of an error in the dosing unit, details must always be read out on the dosing unit. There is basically no differentiated information centrally on a user interface of the dishwasher. For example, only "Dosing error" can be output on the user interface.

DE 10 2018 120 879 A1 describes a dishwasher, in particular a commercial dishwasher, which is designed as a program machine or conveyor dishwasher. The dishwasher has at least one treatment chamber or at least one treatment zone in which, if necessary, washing and/or rinsing liquid is sprayed onto items to be washed. The washing and/or rinsing liquid contains water with metered cleaning chemicals, in particular cleaning agents and/or rinsing agents. The dishwasher also has a chemical cleaning device for preparing the cleaning chemical to be metered in, with the chemical cleaning device being divided into a first area for receiving the cleaning chemical in concentrated form and a second area, separated from the first area, for temporarily storing ready-to-use liquid cleaning chemical solution.

Since dosing systems are generally supplied and installed by detergent companies independently of the dishwasher, the detergent companies or commissioned companies or persons usually install any additional water installation that is required, including disconnection from the mains. This is fundamentally associated with additional effort and additional costs.

Furthermore, the dissolving of the solids basically consumes additional water for operating the dishwasher. An additional control for the dosing technology is required. In addition, a Ver The use and course of the dosing per liter of wash water and errors in the dosing unit are not logged in the dishwasher's log book. In order to obtain this information, an operator always downloads the data from the dishwasher and from the dosing system separately, combines them and logs them.

object of the invention

It is therefore the object of the present invention to provide a dishwasher and a method for cleaning items to be cleaned which at least largely avoid the disadvantages of known devices and methods of the type mentioned. In particular, a simple, inexpensive and integrated dosing technique should be provided.

General Description of the Invention

This object is addressed by a dishwasher and a method for cleaning items to be cleaned with the features of the independent patent claims. Advantageous developments, which can be implemented individually or in any combination, are presented in the dependent claims.

In the following, the terms "have", "have", "comprise" or "include" or any grammatical deviations thereof are used in a non-exclusive manner. Accordingly, these terms can refer both to situations in which, apart from the features introduced by these terms, no further features are present, or to situations in which one or more further features are present. For example, the phrase "A has B," "A has B," "A includes B," or "A includes B" can both refer to the situation in which there is no other element in A other than B (i.e. to a situation in which A consists exclusively of B), as well as to the situation in which, in addition to B, there are one or more other elements in A, e.g. element C, elements C and D or even other elements .

Furthermore, it is pointed out that the terms "at least one" and "one or more" as well as grammatical variations of these terms, if they are used in connection with one or more elements or features and are intended to express that the element or feature is provided once or several times can generally only be used once, for example when the feature or element is introduced for the first time. If the feature or element is subsequently mentioned again, the corresponding term “at least one” or “one or more” is usually no longer used, without restricting the possibility that the feature or element can be provided once or more than once.

Furthermore, the terms “preferably”, “particularly”, “for example” or similar terms are used below in connection with optional features, without alternative embodiments being restricted thereby. Thus, features introduced by these terms are optional features and are not intended to limit the scope of the claims, and in particular the independent claims, by these features. Thus, as will be appreciated by those skilled in the art, the invention may be practiced using other configurations. Similarly, features introduced by "in an embodiment of the invention" or by "in an exemplary embodiment of the invention" are understood as optional features without intending to limit alternative configurations or the scope of the independent claims. Furthermore, through these introductory expressions, all possibilities to combine the features introduced here with other features, be they optional or non-optional features, remain untouched.

In a first aspect of the present invention, a dishwasher for cleaning items to be cleaned is proposed.

In particular, the transport device, for example the drive element, can comprise at least one element selected from the group consisting of: a conveyor belt; transport rollers, in particular driven transport rollers; a link chain; a belt conveyor; a latch transport system.

The transport can take place, for example, continuously or else discontinuously or clocked, so that, for example, continuously operating conveyor dishwashers or else clocked conveyor dishwashers can be implemented. The transport direction can, for example, be a main direction of a movement of the cleaning guts within a cleaning chamber of the conveyor dishwasher. The direction of transport can be fixed or can also change, for example locally or also in terms of time. For example, the transport direction can be directed from an inlet of the conveyor dishwasher towards an outlet.

Furthermore, as stated above, the dishwasher can in particular be a programmable machine. The term "program machine" as used herein is a broad term which should be given its ordinary and current meaning as understood by those skilled in the art. The term is not limited to any specific or adapted meaning. The term can, without limitation, relate in particular to a dishwasher in the sense of the above definition, in which items to be cleaned remain essentially stationary in the dishwasher, in particular in a cleaning chamber of the dishwasher, during a cleaning process. In particular, the items to be cleaned can remain stationary in the cleaning chamber and be cleaned there with at least one cleaning program with several cleaning steps, for example at least one washing step and at least one rinsing or final rinsing step downstream of the washing step.

The dishwasher can in particular have at least one receptacle for the items to be cleaned, in particular crockery and/or cutlery. Depending on the configuration, the dishwasher can have, for example, at least one cleaning basket for the items to be cleaned, in particular the dishes, for example at least one dish basket, and/or at least one holder for at least one cleaning basket in the cleaning chamber, for example at least one holder rail and/or at least one conveyor belt for one or more cleaning baskets. Alternatively, particularly in the case of a conveyor dishwasher, the receptacle can, for example, also be fully or partially integrated into the transport device, for example in the form of a dish conveyor belt which, for example, has receiving fingers for the dishes and/or cutlery and/or also other types of items to be cleaned, such as trays .

The term "cleaning items" as used herein is also a broad term which should be given its ordinary and current meaning as understood by those skilled in the art. The term is not limited to any specific or adapted meaning. The term can, without limitation, refer in particular to any object that can be cleaned using the dishwasher. One object can be cleaned, or several objects can be cleaned simultaneously or sequentially. In particular, the items to be cleaned can be items that are used directly or indirectly for preparing, storing, receiving or serving food, for example crockery, cutlery, trays, bowls, glasses, pots, cups, pans or similar items.

The term "cleaning chamber" as used herein is a broad term which should be given its ordinary and current meaning as understood by those skilled in the art. The term is not limited to any specific or adapted meaning. In particular, the term may refer, without limitation, to a fully or partially enclosed chamber within which the cleaning process may be fully or partially performed. The cleaning chamber can in particular have at least one housing which completely or partially encloses the cleaning chamber. In this case, a single cleaning chamber can be provided, or, in principle, a plurality of cleaning chambers can also be provided, for example sequentially. In particular, it can be a single cleaning chamber, so that the cleaning device can be designed, for example, as a so-called automatic program, as described above.

The term "applying device" as used herein is a broad term which should be given its ordinary and current meaning as understood by those skilled in the art. The term is not limited to any specific or adapted meaning. The term can, without limitation, relate in particular to any device in principle, by means of which the cleaning fluid, in particular at least one cleaning liquid, can be applied to the items to be cleaned within the cleaning chamber. In this context, “acting on” can generally be understood to mean any desired bringing of the items to be cleaned into contact with the cleaning fluid. This can be done in particular in the form of a direct application, for example by spraying, dripping, irradiating or a combination of the above and/or other direct types of application in which the pre-cleaning fluid impinges directly on the items to be cleaned, preferably with a pulse greater than zero.

The application device can in particular comprise at least one nozzle system, for example at least one nozzle arm for example at least one rotatably mounted nozzle arm. For example, at least one nozzle arm, for example a rotatably mounted nozzle arm, can be arranged below the items to be cleaned in the cleaning chamber, and at least one nozzle arm, for example a rotatably mounted nozzle arm, above the items to be cleaned. In this case, for example, separate nozzle arms for washing fluid and after-rinsing fluid can be provided above and below the items to be cleaned.

The term "cleaning fluid" as used herein is a broad term which should be given its ordinary and ordinary meaning as understood by those skilled in the art. The term is not limited to any specific or adapted meaning. The term can, without limitation, relate in particular to a fluid and in particular a liquid which, when it hits the items to be cleaned, can develop a cleaning effect. In particular, the cleaning liquid can include an aqueous liquid, for example water and/or water with one or more additives, for example with one or more cleaning concentrates and/or rinse aids and/or disinfectants. The cleaning device can be set up to use a single cleaning liquid or to use a combination of several cleaning liquids. If several cleaning liquids are provided, the different cleaning liquids can be applied to the items to be cleaned simultaneously or sequentially. For example, as explained above, the items to be cleaned can remain stationary within the cleaning chamber and can be successively treated with the different cleaning fluids. Alternatively, the items to be cleaned can also be transported through the cleaning chamber, for example through a cleaning tunnel, and sequentially treated there with different types of cleaning fluid and/or with cleaning fluids of different degrees of purity in cleaning zones arranged one after the other.

The term "liquid component of the cleaning fluid" as used herein is a broad term which should be given its ordinary and ordinary meaning as understood by those skilled in the art. The term is not limited to any specific or adapted meaning. The term can, without limitation, relate in particular to a component of any cleaning fluid which is in a liquid state of aggregation. The liquid component of the cleaning fluid can in particular have at least one washing-active substance and/or at least one surfactant. In this respect, the liquid component of the cleaning fluid can in particular have at least one liquid detergent concentrate and/or at least one liquid rinse aid concentrate. The liquid component can in particular be at least one substance which in principle offers almost no resistance to a change in shape, but offers a very high resistance to a change in volume. The liquid component can therefore have almost incompressible properties. According to a microscopic definition, the liquid component is a substance whose particles are constantly moving non-periodically and are not subject to long-range order, but are subject to short-range order and whose mean free path is of the order of magnitude of the particle diameter. In principle, the liquid state of aggregation can depend on external factors such as temperature and pressure. In the context of the present invention, the liquid state of aggregation of the liquid component of the cleaning fluid can therefore in particular be a state at room temperature. The liquid component of the cleaning fluid can in particular include water. In principle, however, other liquids are also conceivable.

The term "soluble starting material" as used herein is a broad term which should be given its ordinary and ordinary meaning as understood by those skilled in the art. The term is not limited to any specific or adapted meaning. In particular, the term may refer, without limitation, to any substance which, in solution, is a component of a desired product or mixture and which exhibits soluble properties. In particular, the starting material can be mixed with other substances and thus form the desired product or the desired mixture. The soluble starting material can be in a solid state of aggregation, in particular before contact with a fluid, in particular with a liquid, or can be in a form which contains at least one material in solid form, for example a suspension, a gel, a paste. After the soluble starting material has been dissolved with a solvent, the soluble starting material can be distributed homogeneously in the solvent. The soluble starting material can in particular be selected from the group consisting of: a powder; a granule; a starting material block, in particular a solid block; a gel. Furthermore, the starting material can be selected from the group consisting of: a soluble cleaning agent; soluble rinse aid. In principle, other embodiments are also conceivable. In particular, several liquid components of the cleaning fluid can be present. In particular, one or more other liquid components of the cleaning fluid present. In particular, the liquid components can have different concentrations of the soluble starting material. Furthermore, the liquid component of the cleaning fluid can be mixed with another liquid component of the cleaning fluid and/or another soluble starting material and/or another fluid. In principle, other embodiments are also conceivable.

The dishwasher can have at least two tanks for preparing and providing the cleaning fluid to the application device. The term "tank" as used herein is a broad term which should be given its ordinary and current meaning as understood by those skilled in the art. The term is not limited to any specific or adapted meaning. The term can, without limitation, relate in particular to a completely or partially closed container which is designed to hold at least one fluid, in particular at least one liquid. The at least two tanks can have at least one washing tank, for example. The at least one wash tank can be arranged, for example, in a floor of the cleaning chamber or can also be fluidically connected to the floor of the cleaning chamber, so that cleaning fluid can flow from the cleaning chamber into the wash tank. Furthermore, the at least two tanks can have a post-rinse tank. In the at least one final-rinse tank, for example, at least one final-rinse fluid, also referred to as final-rinse fluid, can be processed, for example temperature-controlled. The post-rinse tank can be designed separately from the wash tank. If several tanks are provided, these tanks can also be in fluid communication with one another. In conveyor dishwashers, for example, several tanks can be fluidically connected to one another against a transport direction in a cascade overflow, so that final-washing fluid can overflow from at least one final-wash tank against the transport direction into at least one upstream wash tank. In programmable machines, for example, final-washing fluid can be transferred from at least one final-washing tank into at least one washing tank during final-washing.

As stated above, the dishwasher includes the dosing system for providing the liquid component of the cleaning fluid. The term "dosing system" as used herein is a broad term which should be given its ordinary and current meaning as understood by those skilled in the art.

In particular, the term may refer, without limitation, to an element that completely or partially encloses or closes off at least one other element or at least one interior space. In particular, the receiving chamber can offer mechanical stability. The receiving chamber can, for example, be made of at least one rigid material, for example at least one metallic material and/or at least one plastic. In principle, other configurations are also conceivable. In particular, the dishwasher can have at least two receiving chambers for receiving at least two different soluble starting materials, in particular at least one detergent and at least one rinse aid.

The receiving chamber can in particular be dimensioned in such a way that it is set up to receive a quantity of the soluble starting material of the liquid component of the cleaning fluid, which is sufficient for several rinsing processes, for example for a plurality of at least 50 or even at least 100 program cycles of a programmable machine, and/or which is sufficient for continuous dishwashing over a longer operating period, for example for an operating period of at least 24 hours, in particular at least 48 hours or even at least 1 week in the case of a conveyor dishwasher. In this respect, the receiving chamber can, for example, have a volume of at least 500 cubic centimeters, in particular at least 1000 cubic centimeters, for example a volume of 500 cubic centimeters to 3000 cubic centimeters.

The dosing system can also have at least one nozzle. The term "nozzle" as used herein is a broad term given its ordinary and ordinary meaning should be as the expert understands them. The term is not limited to any specific or adapted meaning.

In particular, the nozzle can be set up to apply the fluid to at least one object to be applied in a defined manner. Accordingly, the nozzle can have at least one outlet opening through which the fluid can emerge and can act on the object to be acted upon. In particular, the dosing system can have a plurality of nozzles which together form a nozzle system. In particular, the nozzle system can be set up, for example, to direct the fluid in at least one predetermined direction, for example at a predetermined angle, onto the object to be acted upon. Alternatively or additionally, the nozzle system can also be set up to set a pressure, for example a force, with which the object to be acted upon is acted upon by the fluid.

The nozzle can be set up to apply the solvent to a supply of the starting material held in the receiving chamber. In particular, as described above, the nozzle can have at least one outlet opening through which the solvent can emerge and the supply of starting material can be admitted. The dishwasher, in particular the dosing system and/or the control element, can have at least one pressure-boosting pump. The pressure booster pump can be set up to supply the nozzle with overpressure of the solvent. The pressure-boosting pump can in particular be or include a centrifugal pump.

The dishwasher, in particular the dosing system and/or the control element, can have at least two pressure-boosting pumps. The at least two pressure-boosting pumps can be connected in series, in particular to increase a pressure. In principle, other embodiments are also conceivable.

In particular, the nozzle can be arranged below the reservoir, as a result of which the reservoir can be dissolved from below and the liquid component of the cleaning fluid formed in the process drips off downwards. The receiving chamber can have a collection device, in particular a collection funnel, on the floor. The receiving chamber can be set up to collect the liquid component and to feed it to the application device.

The dishwasher can have at least two supply lines for supplying the liquid components of the cleaning fluid formed in the receiving chambers to the application device, in particular to at least two separate tanks of the application device. The term "feed line" as used herein is a broad term which should be given its ordinary and current meaning as understood by those skilled in the art. The term is not limited to any specific or adapted meaning. The term can, without limitation, relate in particular to an element or a device which is set up to supply at least one further element which is fluidically connected to the feed line with a fluid. In the present case, for example, the supply line can include at least one connection for the fluid. The feed line can, for example, comprise at least one fluid-carrying pipe and/or pipe system.

At least one outlet of the at least one dosing system can be fluidically connected to at least one element selected from the group consisting of: at least one wash tank of at least one washing device of the dishwasher; at least one pump rinse tank; at least one fresh water rinse of the dishwasher; an input of a heating device of at least one fresh water rinse of the dishwasher, in particular at least one boiler.

Alternatively or additionally, the dishwasher can have one or more conductivity sensors, by means of which a detergent concentration can be detected, for example.

As described above, the dishwasher can be the conveyor dishwasher with the at least one conveyor device. The loading device can have at least one washing device and at least one pump rinsing device downstream of the washing device in the transport device. The dishwasher can have at least two of the dosing systems and the dosing systems can have at least one detergent dosing system connected to at least the wash tank of the washing device and at least one rinse aid dosing system connected to at least one fresh water rinse.

As explained above, the dishwasher has the fresh water supply. The term "fresh water" as used herein is a broad term which should be given its ordinary and current meaning as understood by those skilled in the art. The term is not limited to any specific or adapted meaning. The term can, without limitation, particularly refer to an unused water. The water can be at least largely free of impurities. The fresh water can in particular be water of drinking water quality. In particular, the water can be used fresh for a single rinsing phase or a single rinsing process. A water change can therefore be carried out after each individual rinsing phase or after each individual rinsing process. The term "fresh water supply" as used herein is a broad term which should be given its ordinary and current meaning as understood by those skilled in the art. The term is not limited to any specific or adapted meaning. The term can, without limitation, relate in particular to an element or a device which is set up to supply fresh water to at least one further element which is fluidically connected to the fresh water supply.

The distribution system can be set up to provide a desired quantity of fresh water in a desired quality and/or with a desired pressure. The on-site fresh water network can be designed as a drinking water network.

As described above, the fresh water network is an on-site fresh water network. The term "customer" as used herein is a broad term which should be given its ordinary and current meaning as understood by those skilled in the art. The term is not limited to any specific or adapted meaning. The term may refer particularly, without limitation, to a property of any device not to be encompassed by another device, but specifically to be provided by a building in which the device is housed. The device can therefore be set up or made available in principle independently of the other device being set up or made available. In particular, when the dishwasher is made available, in particular when it is set up and/or put into operation, the fresh water connection can already be present. The on-site fresh water connection can therefore also be referred to as a building-side fresh water connection.

As stated above, the fresh water supply has the mains separation. The term "network isolation" as used herein is a broad term that should be given its ordinary and current meaning as understood by those skilled in the art. The term is not limited to any specific or adapted meaning. The term can, without limitation, refer in particular to any device that is set up to separate a circuit of a fluid from another circuit of another fluid, in particular in such a way that a transition of the fluid into the further circuit and/or a transition further fluid is prevented from entering the circuit. In particular, the network separation can be set up to avoid a transfer of fresh water contaminated with chemicals and/or dirt and/or germs into the fresh water network or the drinking water network.

The network separation can have at least one collection vessel. The fresh water connection can have at least one connection that can be connected to the on-site fresh water network and at least one free outlet opening into the collection vessel. The fresh water connection can also have at least one controllable valve, in particular a solenoid valve, between the connection and the free outlet. The fresh water connection can also have at least one float valve in the collection vessel. The float valve can be set up to introduce fresh water into the collection vessel. Furthermore, the float valve can be set up to regulate the inflow of fresh water into the collection vessel. The network separation can also have a free inlet, in particular an air gap, with the network separation being set up to introduce the fresh water into the collection vessel via the air gap. An outlet opening of a supply of water can be arranged in such a way that the outlet opening lies above a water surface even in the case of the highest possible water level in the collecting vessel. In principle, however, other designs are also conceivable.

As stated above, the cleaning device is set up to take up water via the fresh water supply with the mains separation and the cleaning device is also set up to form at least one heated solvent using the water. The term "heated solvent" as used herein is a broad term which should be given its ordinary and ordinary meaning as understood by those skilled in the art. The term is not limited to any specific or adapted meaning. In particular, the term can refer, without limitation, to any solvent which, as a result of at least one heating process, is at a higher temperature than an ambient temperature of an external environment of the solvent. The heated solvent can in particular have a temperature of 30°C to 90°C, in particular of 40°C to 70°C. In principle, other temperatures are also conceivable. The dishwashing machine may have at least one heating device for heating at least one element selected from the group consisting of the absorbed water and the solvent formed by means of the water. The heating device may include at least one device selected from the group consisting of: a boiler; a water heater; a tank heater of at least one tank of the dishwasher, in particular a wash tank and/or a final-rinse tank; a heat recovery device for heating the solvent with waste heat from the dishwasher, a heating device specially provided for heating the solvent. In principle, however, other embodiments are also conceivable.

As stated above, the cleaning device has a solvent supply to the receiving chamber. The term "solvent supply" as used herein is a broad term which should be given its ordinary and current meaning as understood by those skilled in the art. The term is not limited to any specific or adapted meaning. The term can, without limitation, refer in particular to an element or a device which is set up to supply the solvent to at least one further element which is fluidly connected to the solvent supply. The solvent supply can, for example, comprise at least one solvent-carrying pipe and/or pipe system. The solvent supply may be fluidly connected to the receiving chamber with at least one element selected from the group consisting of: the fresh water supply of the warewashing machine downstream of the mains separation; the fresh water supply of the dishwasher after it has passed through at least one heating device for heating supplied fresh water, in particular at least one heat recovery device for heating the solvent with waste heat from the dishwasher, an outlet of at least one heating device of at least one fresh water rinse, in particular at least one boiler; a circulation tank of at least one pump rinse; a heating device which is specially designed for heating the solvent. In principle, other designs are also conceivable.

As stated above, the solvent supply is separate from the application device. The term "separately formed" as used herein is a broad term which should be given its ordinary and current meaning as understood by those skilled in the art. The term is not limited to any specific or adapted meaning. In particular, the term may refer, without limitation, to a property of two or more devices to be functionally independent of one another in at least one respect. In particular, the two or more devices can be started up independently of one another, so that, for example, at least one function of at least a first of the devices can be performed independently of at least one function of at least a second of the devices in terms of time, function or space. In particular, the loading of the items to be cleaned and the supply of the solvent can take place independently of one another. For example, the action on the items to be cleaned and the supply of solvent to the receiving chamber can take place at separate times and/or be controlled separately. In particular, the supply of solvent to the receiving chamber can be designed separately from a nozzle system of the application device, so that the supply does not take place via the nozzle system of the application device. Nevertheless, in the formation of the solvent upstream of the supply of solvent to the receiving chamber, the application device can be integrated, for example a tank of the application device, for example by using the application device or a part thereof for a mixture of the solvent and/or a temperature control of the solvent . However, the actual supply of the solvent to the receiving chamber with the starting material received therein takes place independently of the application device, so that in particular operation of the application device, for example operation of the nozzle system, can be independent of dissolution of the starting material. For example, the dissolution can take place as required and/or in portions, regardless of whether the nozzle system of the application device is currently in operation or not. On the other hand, the nozzle system can be operated regardless of whether dissolution of the raw material is desired or not, since this dissolution can be controlled independently. Furthermore, the action on the items to be cleaned and the supply of solvent can also be carried out simultaneously, with a time overlap or else repeatedly.

As explained above, the solvent supply has the control element for controlling the supply of the solvent into the receiving chamber. The term "driver" as used herein is a broad term that should be given its ordinary and current meaning as understood by those skilled in the art. The term is not limited to any specific or adapted meaning. In particular, the term may refer, without limitation, to any element configured to control a flow of a fluid medium. The control can in particular include conveying, admitting, discharging and/or shutting off the fluid medium. The control element can have at least one element selected from the group consisting of: a valve; a pump; a slider, a cock. In principle, other elements are also conceivable. The valve may comprise at least one valve selected from the group consisting of: a valve in the solvent supply of the receiving chamber; a valve in a connection between the receiving chamber and the applying device. In principle, other configurations are also possible.

The dishwasher can also have at least one controller. The controller can be set up to control the application device. The term "control" as used herein is a broad term that should be given its ordinary and current meaning as understood by those skilled in the art. The term is not limited to any specific or adapted meaning. The term can refer, without limitation, in particular to a one-piece or multi-piece device of the dishwasher, which is set up to fully or partially control and/or regulate operation of the dishwasher. In particular, the controller can be set up to change, in particular to control and/or regulate, one or more operating parameters of the dishwasher, for example at least one temperature, at least one pressure or also a combination of two or more operating parameters. In particular, the controller can include at least one data processing device, for example at least one processor. In particular, the controller can be set up in terms of programming, for example in order to control at least one cleaning program of the dishwasher. In particular, the controller can also be set up to activate the activation element. Within the scope of the present invention, “activation of the actuation element” is basically to be understood as a type of operation of the actuation element, in particular starting and/or stopping pen of a promotion, an admission, a discharge and / or a shut-off of the solvent and in particular a change in the speed of the promotion of the solvent. In particular, the controller can be set up to actuate the control element during continuous operation of the dishwasher in such a way that repeatedly predeterminable amounts of the solvent are supplied to the receiving chamber, repeatedly predeterminable amounts of the liquid component of the cleaning fluid being able to be generated. The controller of the dishwasher can in particular be a single controller which is set up to activate and/or control both the activation element and the application device. As a result, data from the control element and the application device can be brought together and displayed on the single controller. The controller can also be set up to log data from the control element and/or the application device, in particular data from the control element and the application device. The logging can in particular include storing or recording the data. As a result, dosing can be documented and diagnosed with the controller, in particular with the single controller.

The dishwasher can also have at least one mixing device. The mixing device may be a mixing device operated by the controller. The term "mixing device" as used herein is a broad term which should be given its ordinary and current meaning as understood by those skilled in the art. The term is not limited to any specific or adapted meaning. The term can, without limitation, refer in particular to any device that is set up to produce a mixture of substances from two or more substances. Mixing can take place with at least one fixed predetermined mixing ratio, or mixing with at least one variable or adjustable mixing ratio can also take place.

The term "temperature controlled mixing device" as used herein is a broad term which should be given its ordinary and current meaning as understood by those skilled in the art. The term is not limited to any specific or adapted meaning. The term can, without limitation, relate in particular to any mixing device which is set up to set and/or regulate a temperature of at least one substance from which a substance mixture is produced and/or a produced substance mixture.

The mixing device can in particular have at least one supply line for supplying the substances. In particular, the mixing device can have at least two feed lines. In particular, the mixing device can be set up to mix solvents at different temperatures in an adjustable ratio and to supply them to the receiving chamber via the solvent supply. In the context of the present invention, the term “solvents at different temperatures” refers to the presence of at least one first solvent, which has a first temperature, and at least one second solvent, which has a second temperature, the first temperature and the second temperature differing from one another. The feed lines can be connected to at least two different heating devices in order to provide the solvents at different temperatures, in particular solvents heated at different temperatures. Alternatively or additionally, one of the feed lines can be set up for an inflow of cold solvent, in particular cold water. In the context of the present invention, the term “cold solvent” denotes that an average temperature of the solvent essentially corresponds to an average ambient temperature of an external environment of the solvent. In particular, one of the two feed lines can be set up for an inflow of cold solvent, and another of the two feed lines can be connected to one of the heating devices in order to provide a heated solvent.

The control element can be at least partially integrated into the mixing device. The control element and the mixing device can form a common unit. The dishwasher can have a device in which the control element and the mixing device are arranged. The controller can be set up to regulate the control element and the mixing device. In particular, the controller can be set up to regulate a supply of fluids to the mixing device and/or a mixture of fluids carried out by the mixing device.

The application device can have at least one final rinse for applying final-rinse fluid to the items to be cleaned, in particular a fresh-water final rinse. The final rinse can have at least one heating device for heating the final rinse fluid, in particular at least one boiler. The dishwasher can have at least one connection between the final rinse and the solvent supply and can be set up to heat the final rinse fluid in the heating device of the final rinse as a solvent via the solvent supply of the on supply chamber. The fresh water supply can be connected to the solvent supply to the receiving chamber via at least one branch, in particular a branch arranged between the mains separation and the heating device of the final rinsing. At least one outlet of the dosing system can be connected to the fresh water supply and set up to supply the fresh water supply with the liquid component in the form of a dissolved starting material of a rinse aid starting material.

The fresh water supply can have at least one heating device, in particular at least one heat recovery system. The heating device for the final rinse can be connected via at least one final-rinse line to at least one final-rinse nozzle system for the final rinse, in particular at least one fresh-water final-rinse nozzle system. The final-rinse line can be connected to the solvent supply to the receiving chamber via at least one branch. Solvent streams from the fresh water supply and from the rinsing line can be mixed via at least one mixing device and can be fed to the receiving chamber via the solvent supply.

At least one heating device specially provided for heating the solvent can be arranged between the branch and the dosing system. The solvent supply to the receiving chamber can be fluidly connected to at least one circulating tank of at least one pump rinse. At least one outlet of the at least one dosing device can be fluidically connected to an inlet of a heating device of at least one fresh water rinse of the dishwasher.

In a further aspect of the present invention, a method for cleaning items to be cleaned is proposed. The method includes the use of at least one dishwasher as has already been described or will be described below. For further details regarding the dishwasher, reference can therefore be made to the above description and to the following description of the figures.

The procedure includes the steps listed below. In particular, the steps can be carried out in the order mentioned. Furthermore, one or more of the method steps can also be carried out simultaneously, overlapping in time or repeated. The method can include further steps that are not mentioned.

1. i. Bereitstellen mindestens eines löslichen Ausgangsstoffs der flüssigen Komponente des mindestens einen Reinigungsfluids in der Aufnahmekammer des Dosiersystems;
2. ii. Bereitstellen des mindestens einen erwärmten Lösungsmittels;
3. iii. Beaufschlagung des Ausgangsstoffs mit dem mindestens einen Lösungsmittel und Erzeugung der flüssigen Komponente in Form von in dem Lösungsmittel gelöstem Ausgangsstoff; und
4. iv. Zuführen der flüssigen Komponente zu der Beaufschlagungsvorrichtung.

The procedure includes the following steps:

1. i. providing at least one soluble starting material of the liquid component of the at least one cleaning fluid in the receiving chamber of the dosing system;
2. ii. providing the at least one heated solvent;
3. iii. Subjecting the starting material to at least one solvent and producing the liquid component in the form of starting material dissolved in the solvent; and
4. IV. supplying the liquid component to the application device.

The source may be selected from the group consisting of: a soluble detergent; soluble rinse aid. The soluble source may be selected from the group consisting of a powder; a granule; a starting material block, in particular a solid block; a gel. In principle, other embodiments are also conceivable. At least two different types of cleaning fluid can be used in the dishwasher. In particular, at least two dosing systems can be provided and in step i. different types of soluble starting materials can be provided in the dosing systems. The cleaning fluids can include at least one washing fluid. In at least a first of the dosing systems, at least one soluble starting material can be provided in the form of a soluble cleaning agent. The cleaning fluids can also include at least one rinsing fluid. At least one soluble starting material in the form of a soluble rinse aid can be provided in at least a second of the dosing systems. The process can include multiple cleaning cycles. In particular, in step i. the soluble starting material for the multiple cleaning cycles are provided as a supply.

The proposed devices and the proposed methods have numerous advantages over known devices and methods of the type mentioned. In principle, a simple, less expensive and integrated solution can be provided. From a control point of view, this can basically be implemented with a joint control of the dishwasher and the dosing technology. All relevant data can be brought together and displayed in an operations log. It can be both the solvent, especially water, for a cleaning chemistry, as well as thermal energy for a heating of the solvent can be taken directly from the dishwasher.

In principle, a joint control for the dishwasher and the dosing technology is possible, resulting in cost savings and consistent logging of the operating parameters in the service log. In principle, this is of great benefit to an operator and can in principle also be implemented in small machines such as program machines. Basically, costs can be saved through a simple water-technical installation. Regulations for drinking water installations can be complied with by using the fresh water mains disconnection, which is basically present in every dishwasher anyway. Factory pre-installation under standard conditions is fundamentally possible, which can result in a quality and cost advantage for an overall machine and dosing system.

When using liquids from the dishwasher, the temperature of the solvent is fundamentally known. Additional water consumption, or a supply of fresh water to the tanks, during operation can be avoided in principle if replenishment is required.
