Description

Technical area

The invention relates to a rinsing system and a method for cleaning items to be cleaned with at least one cavity. In particular, the rinsing system and the method can be used for cleaning vessels, in particular for cleaning bottles. The invention can be used in particular in the field of dishwashing technology, in particular in the field of commercial dishwashing technology. The invention can thus be used in particular in large kitchens in which items to be cleaned, for example trays, dishes and cutlery, have to be cleaned in large quantities. In particular, the invention can be used to clean bottles, for example bottles for table water in restaurants, or other bottle-like objects such as wine carafes, lemonade jugs or similar items to be cleaned with at least one cavity. However, other areas of application are also fundamentally conceivable.

Technical background

A large number of cleaning devices, also referred to as cleaning devices, which can clean and / or disinfect items to be cleaned, are known from the prior art. Overall, the design of these cleaning devices depends largely on the various boundary conditions, such as, for example, the type of items to be cleaned, the soiling, the throughput or similar conditions. As an example, reference can be made to cleaning devices, which are for example in DE 10 2004 056 052 A1 or in DE 10 2007 025 263 A1 are described.

Special technical challenges arise in particular when the items to be cleaned have one or more cavities. In this case, it must be ensured that the inner walls of the cavity have sufficient cleaning fluid applied to them in order to be able to ensure a reliable cleaning and sanitizing effect there as well. This problem arises in particular when cleaning bottles, in particular reusable bottles, which typically have a narrow neck and an adjoining widened cavity. In order to be able to reliably clean such items to be cleaned, washing racks are known which can be used in dishwashers and which have a nozzle system for attaching the bottles. One example here are the washing baskets from Dishmachines (www.cmadishmachines.com) from Garden Grove, CA 92841, USA. Another example is shown in DE 10 2016 114 589 B3 and in WO 2018/024772 A1 described. This document describes a bottle washing basket device for a commercial dishwasher with two separate washing systems, which comprises a basket carrier and a washing basket for receiving bottles to be cleaned. The basket support comprises a docking device with at least two separate feed channels, and the washing basket comprises a distributor system with a distributor flange which can be connected to the docking device of the basket support. Furthermore, a dispensing tube for dispensing liquid onto bottles to be cleaned is provided, which is connected to a common distribution channel of a distribution system, whereby liquids from each of the two rinsing systems can be supplied to this dispensing tube via the common distribution channel.

A particular technical challenge, however, is the drying of the items to be cleaned, in particular the cavity, i.e. the inner walls of the items to be cleaned. For efficient drying, the individual pieces of the items to be cleaned would have to be turned around after a rinsing process and a subsequent draining phase, so that their openings are directed upwards. The residual moisture can then evaporate and escape upwards, so that drying is guaranteed. However, this process would require an interruption of a program and manual intervention, which would hardly be feasible, especially in the field of commercial warewashing technology, which would be extremely time-consuming and would also require high personnel costs.

Out U.S. 2,480,227A a sterilizer is known which can be used for drying and sterilizing dairy equipment. In this sterilizer, hot air is blown into a milking bucket inside the drying cabinet for the purpose of killing germs.

Out U.S. 5,010,660 a device for rinsing and vacuum drying long-necked laboratory bottles is known. The device comprises a basket which can be rolled into a washing chamber and which comprises a distributor pipe. Upright tubes extend into the bottles from the manifold. After exposure to water, the tubes can be used to apply a vacuum to the bottles, a vacuum blower sucking moist air from the bottles during drying and replacing this with drier air from the washing chamber.

Despite the advantages achieved with this device, some technical challenges remain. The use of a drying cabinet is very complex in practice. Furthermore, in In many cases the drying effect of the devices used is inadequate despite a comparatively high handling effort, and the drying result is often uneven. In addition, a period of time for performing the drying is comparatively long, in particular for example in the case of bottles with a narrow bottle neck. Furthermore, in particular when using the vacuum device described, a comparatively high level of equipment expenditure is necessary, since the vacuum blower used must as a rule be set up to convey moist air. In addition, even after the actual rinsing process, the washing chamber usually still contains warm, moist air, which flows into the cavity during suction, so that moist air remains in the cavity and can negatively affect the drying result.

Object of the invention

It would therefore be desirable to provide a device and a method for cleaning items to be cleaned with at least one cavity, which at least largely avoid the disadvantages of known devices and methods of the type mentioned. In particular, efficient drying of the items to be cleaned should be made possible, with little expenditure on equipment and yet with a reliable drying result.

As will be explained in more detail below, the pressurizing device can comprise its own pressurized gas source or its own device for generating pressurized gas, and / or can comprise at least one device which can provide pressurized gas from an external source to the dishwasher, for example a pressure port, a pressure reducer or a pressure connection.

The term “washing basket” as used here is a broad term to which its usual and common meaning should be assigned as understood by the person skilled in the art. The term is not limited to any specific or adapted meaning. The term can, without limitation, refer in particular to a portable receiving device in which items to be cleaned can be received, placed in a dishwasher and then taken out of the dishwasher again in a cleaned state. Furthermore, washing baskets can also be used to temporarily store items to be cleaned, for example cleaned glasses or bottles. The washing basket can in particular have a plurality of openings so that liquid can drip downwards.

The wash basket can in particular have a substantially cuboid shape, with a basket base, which can have a square or generally rectangular plan, for example, and which has a support surface for placing the wash basket on a flat work surface. As will be described in more detail below, a basket frame can optionally extend upwards from the basket base, for example with a raised edge and also optionally other elements such as handles.

As stated above, the washing basket comprises the basket base. The term "basket floor" as used here is a broad term to which its usual and common meaning should be ascribed to the person 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 which closes the washing basket at the bottom when it rests on a support surface. The basket bottom can in particular be designed to be essentially flat. So this can have a flat support surface on its underside. On its surface, too, the basket bottom can, for example, be designed essentially flat. The basket bottom can in particular be designed to be square or generally rectangular. The basket bottom can for example be made entirely or partially from a plastic material, in particular from a thermoplastic plastic material. The basket bottom can furthermore have a plurality of openings which allow liquid to run off through the basket bottom.

The wash basket further comprises a plurality of nozzles extending from the basket bottom. For example, the basket base can have an underside with a support surface for placing the washing basket on a work surface, and an upper side opposite the underside and essentially parallel to the underside, the nozzles extending from the upper side. For example, the nozzles can be arranged essentially perpendicular to the upper side and / or to a plane of the washing basket, for example a plane in which the support surface is arranged. Deviations from a vertical orientation can also be acceptable, for example deviations of up to 45 °, for example in order to be able to accommodate bottles at an angle in the washing basket. The nozzles can, for example, extend at least 40 mm from the bottom of the basket, for example 50 mm to 200 mm. The nozzles can extend into a basket interior, for example, which can be bordered by the basket base and a basket frame.

The term “nozzle” as used here is a broad term to which its usual and common meaning should be assigned, as understood by the person skilled in the art. The term is not limited to any specific or adapted meaning. The term can, without limitation, refer in particular to a device which is set up to apply a fluid, that is at least one liquid and / or at least one gas, to another object, for example to spray, inflate or drop it on. In particular, the nozzle can have a nozzle body in which one or more feed lines are arranged, as well as at least one nozzle opening through which the liquid can exit the nozzle, for example as a jet, bundle of rays or drops. The nozzle body can in particular be made entirely or partially from at least one plastic material. However, another configuration is also possible, for example a configuration made of metal. The nozzle body can in particular be designed to be essentially elongated, with a length which exceeds a diameter by at least a factor 2, in particular by at least a factor 3 or at least a factor 4. The nozzle body can, for example, have an essentially cylindrical design.

For example, one or more fluid feeds can be provided in the basket bottom. The fluid feeds can for example comprise at least one washing fluid feed and at least one final rinse fluid feed, it being possible for these two fluid feeds to be designed together or also separately. The term “fluid supply”, as used here, is a broad term to which its customary and common meaning is to be assigned, as understood by the person 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 channel or channel structure which enables fluid, in particular washing fluid and rinse aid fluid, to be supplied from the outside into the washing basket and to the nozzles. As will be explained in more detail below, the at least one fluid supply can in particular comprise one, two or more channels which are integrated in the basket bottom. The at least one fluid supply can, for example, be connected to at least one opening via which a fluid supply from the outside is possible, i.e. for example at least one washing fluid opening of the at least one washing fluid supply and at least one final rinsing fluid opening of the at least one final rinsing fluid supply, or alternatively a common opening for the fluid supply.

The term “fluid”, as it is used here in connection with the terms “washing fluid” and “rinsing fluid”, is a broad term to which its customary and common meaning should be assigned, as understood by the person 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 liquid which can develop a cleaning effect when it hits the items to be cleaned. In particular, the fluid can comprise an aqueous liquid, for example water and / or water with one or more additives, for example with one or more cleaning concentrates and / or rinsing agents and / or disinfectants. Accordingly, a washing fluid can be understood to mean, for example, a fluid which can be used for a washing process and which can comprise, for example, water and detergent concentrate. The final rinse fluid can, for example, have a higher temperature than the washing fluid and can, for example, also comprise water, which, however, can for example be mixed with a rinse aid.

The nozzles can, for example, each have at least one fluid channel, that is to say a fluidic line which fluidly connects at least one nozzle opening of the nozzle to the at least one fluid supply. The fluid can exit through the nozzle opening and act on the items to be cleaned. A single fluid channel and a single nozzle opening can be provided, or separate channels and separate openings can also be provided.

As stated above, the application device is set up to apply the cleaning fluid to the cavity of the items to be cleaned, in particular with at least one cleaning liquid, in at least one cleaning step by means of the nozzles, and to open the cavity of the cleaning product in at least one drying step by means of the nozzles to apply compressed gas to the nozzles of the items to be cleaned. For example, the washing system, in particular the dishwasher, can have at least one controller which is set up to control at least one program which comprises at least the cleaning step and the drying step as program steps, in particular as separate program steps. For example, one or more cleaning steps can be included in which the cleaning fluid, in particular the cleaning liquid, is applied, for example at least one washing step with the application of washing fluid and then at least one final rinse step with the application of the final rinse fluid, with the at least one Cleaning step is followed directly or indirectly by at least one drying step with the application of the pressurized gas. The dishwasher can in particular be designed as a program machine. One or more special cleaning programs can be provided for cleaning with the washing basket described. For example, a regular cleaning program with at least one washing step and at least one final rinse step can be provided. Alternatively or additionally, one or more further programs can be provided which fulfill special functions. Thus, one or more programs can also be provided which include at least one decalcifying step for decalcifying the items to be cleaned by means of the nozzles, for example by means of a special decalcification chemistry in the washing fluid. Alternatively or additionally, one or more other types of special cleaning steps can also be carried out by means of the nozzles. Again, as an alternative or in addition, at least one bottle cleaning program can be provided in which at least one washing step and / or at least one final rinse step are provided, which do not run continuously, but in which the application of washing fluid and / or final rinse fluid is interrupted once or several times. In particular, the application of washing fluid can be interrupted, with the application of final rinse fluid also being able to take place continuously. For example, washing fluid can be circulated in the circulation mode with time interruptions. The interruption of the application of fluid can in particular prevent the interior of the vessels from being filled with fluid, in particular an interior of the bottles, since sufficient drainage of the fluid through the narrow bottle neck is often prevented. As a result of the interruptions, any pent-up washing fluid and / or rinse aid fluid can run out of the interior, so as not to impair the jet that resumes in the bottle and thus ensure good cleaning performance.

The proposed rinsing system can in particular enable efficient drying of the items to be cleaned. The rinsing system can be implemented with comparatively little expenditure on equipment and still achieve a reliable drying result. The use of a special blower that is suitable for conveying moist air is generally not required. In addition, easy handling of the washed items to be cleaned can be ensured. A reliable drying result can be guaranteed by a forced exchange of air within the cavities of the items to be cleaned, for example within the bottles.

The pressurizing device can in particular comprise at least one fan integrated in the dishwasher. This fan can for example comprise at least one fan wheel. For example, it can be a fan wheel driven by an electric motor. The fan can in particular be integrated in a locking device of the dishwasher, in particular in a door. For example, the dishwasher can include a front-loading dishwasher, for example a front-loading dishwasher configured as a program machine, wherein the fan can be integrated, for example, in a door configured as a front flap, for example in a paneling of the door or front flap. Alternatively, the fan can also be arranged, for example, on an outside of the door. If other types of closure devices are provided, then for example the fan can be integrated in this other type of closure device. As an alternative or in addition, however, the fan can also be fully or partially integrated into other components of the dishwasher.

The fan can in particular comprise at least one energy supply, for example at least one power supply unit for an external energy supply and / or at least one energy store. In general, the energy supply can for example be selected from the group consisting of: an external energy supply, in particular via at least one power supply unit; an energy store, in particular an accumulator; an inductive power supply.

As stated above, the pressurization device can also make use of pressurization which is based on a pressurized gas source arranged outside the dishwasher. This can be, for example, an external compressor, an external compressed gas cylinder or an on-site compressed gas line. A combination of the options mentioned is also conceivable. For example, the pressurizing device of the dishwasher can have at least one pressurized gas connection, and the rinsing system can furthermore have at least one external pressurized gas source which is arranged wholly or partially outside the dishwasher. The external compressed gas source can be connected to the compressed gas connection, for example by a hose connection and / or a pipeline. For example, the dishwasher can have at least one pressure port and / or another type of pressurized gas connection, for example with a quick-release fastener and / or a screw connection, the pressurizing device of the dishwasher can or is connected to the external pressurized gas source via the pressure port. The external The compressed gas source can in particular comprise at least one device selected from the group consisting of: an external drying unit, in particular an external fan and / or an external compressor; an on-site compressed gas line.

The flushing system can furthermore have at least one processing device in order to process the compressed gas before the items to be cleaned are applied. The term “processing device” as used here is a broad term to which its customary and common meaning should be assigned, as understood by the person 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 device which is set up to influence at least one property of the compressed gas before the items to be cleaned are applied, for example at least one property selected from the group consisting of: a purity of the compressed gas; a chemical composition of the compressed gas; a moisture content of the compressed gas; a particle loading of the pressurized gas; a germ loading of the compressed gas. The processing device can for example comprise at least one element selected from the group consisting of: a drying device; a filter; a temperature control device.

• - das Spülsystem kann eingerichtet sein, um die Druckgaszuführung und den Druckgaskanal wahlweise mit Reinigungsfluid oder mit Druckgas zu beaufschlagen, wobei in dem Spülkorb vorzugsweise mindestens ein Rückschlagventil zur Trennung von Druckgas und Reinigungsfluid vorgesehen ist; oder
• - in dem Korbboden kann weiterhin mindestens eine von der Druckgaszuführung getrennt ausgebildete Fluidzuführung vorgesehen sein, und in den Düsen kann jeweils mindestens ein von dem Druckgaskanal getrennt ausgebildeter Fluidkanal vorgesehen sein, wobei das Spülsystem eingerichtet ist, um mittels der Beaufschlagungsvorrichtung die Fluidzuführung und den Fluidkanal mit Reinigungsfluid zu beaufschlagen und mittels der Druckbeaufschlagungsvorrichtung getrennt die Druckgaszuführung und den Druckgaskanal mit Druckgas zu beaufschlagen.

At least one compressed gas supply can be provided in the basket bottom. At least one compressed gas channel can be provided in each of the nozzles, wherein the compressed gas supply can be fluidically connected to the compressed gas channel. In this way, pressurized gas can be applied up to a nozzle opening. The rinsing system can in particular be designed in one of the following ways in order to cause the cleaning fluid to be applied to the items to be cleaned:

• The rinsing system can be set up to pressurize the pressurized gas supply and the pressurized gas channel either with cleaning fluid or with pressurized gas, with at least one check valve preferably being provided in the wash basket for separating pressurized gas and cleaning fluid; or
• - In the basket bottom at least one fluid supply formed separately from the compressed gas supply can be provided, and in each of the nozzles at least one fluid channel formed separately from the compressed gas duct can be provided, wherein the flushing system is set up to use the application device to control the fluid supply and the fluid duct To apply cleaning fluid and to apply compressed gas separately to the compressed gas supply and the compressed gas channel by means of the pressure application device.

For example, a common line system can be used for the cleaning fluid and the pressurized gas in the washing basket, the inlets being able to be locked against one another, for example, via at least one valve and / or check valve, or separate line systems can be used for the at least one cleaning fluid and the pressurized gas Wash basket be provided.

The dishwasher can in particular be set up in such a way that the pressurizing device is automatically coupled to the pressurized gas supply. This automatic coupling, that is to say without a user having to operate a release mechanism separately for this, can take place, for example, as part of a program sequence, for example controlled by a control of the dishwasher. Alternatively or in addition, the automatic coupling can take place during a certain movement process of the dishwasher, which serves at least one other purpose. As stated above, the dishwasher can in particular have at least one closure device, for example at least one door, in particular a front flap. The pressurizing device can be set up in such a way that this closure device automatically couples to the pressurized gas supply when it closes, in particular by pressing the pressurizing device against the washing basket. As stated above, the pressure application device can, in particular, be fully or partially integrated into the closure device, for example the front flap. When closing, for example, the fan or a pressure port connected to the fan or another gas-carrying part of the pressurizing device can be pressed against a corresponding opening in the washing basket so that a gas-tight connection can be created.

The spray system can also have at least one connection adapter to connect the dishwasher and the wash program. The connection adapter can in particular be set up to fluidically connect the loading device of the dishwasher to the washing rack introduced into the cleaning chamber. The connection adapter can in particular be designed separately from the pressurizing device.

As used here, the term “connector adapter” is a broad term that has given its ordinary and common meaning should be as the skilled person understands them. The term is not limited to any specific or adapted meaning. The term can, without limitation, relate in particular to a device which is set up to fluidically connect a fluidic system of the dishwasher, in particular a loading device of the dishwasher, to a washing basket. The connection adapter can in particular have at least one main body which can serve as a carrier for the washing rack and which has at least one channel structure for the fluidic connection of the dishwasher to the washing rack. The connection adapter can be designed in one piece or in several pieces.

The connection adapter can in particular be reversibly mountable on a wash arm hub of the dishwasher, in particular a loading system of a dishwasher. The term “wash arm hub” as it is used here is a broad term to which its usual and common meaning should be assigned, as understood by the person skilled in the art. The term is not limited to any specific or adapted meaning. The term can, without limitation, refer in particular to a dishwasher-side component or a combination of several dishwasher-side components which are designed to hold a wash arm mechanically, in particular to keep it rotatable, and / or which are designed to hold a To apply washing arm with at least one cleaning fluid. The wash arm hub can itself be mounted rigidly or movably, for example. For example, the wash arm hub itself can be received in a fixed and non-rotatable manner in the cleaning chamber and can for example itself provide a bearing for the at least one wash arm, in particular a pivot bearing for the at least one wash arm. In particular, the wash arm hub can comprise at least one component of the dishwasher which on the one hand has a bearing pin for the at least one wash arm and which also has at least one fluid channel for at least one cleaning fluid, for example at least one fluid channel for at least one washing fluid and at least one fluid channel for at least one Rinse aid. The wash arm hub can in particular also have at least one component with which the wash arm can be attached in the dishwasher, in particular in the cleaning chamber.

For the reversible mounting of the connection adapter on the wash arm hub of the dishwasher, the connection adapter can for example have a connection socket which can be plugged onto the wash arm hub so that, for example, a wash fluid line in the connection adapter is supplied with wash fluid from the wash arm hub and a rinse aid line in the connection adapter is supplied with rinse aid fluid from the wash arm hub. In this way, the connection adapter can be connected to the fluid systems of the dishwasher.

As will be described in more detail below, the reversible connection can be made in particular by a plug-in system, for example a plug-in system with a quick-release fastener. For example, the connection adapter can have at least one manually actuatable latch which can be released in order to attach the connection adapter to the wash arm hub and to remove it again from the wash arm hub. For example, instead of a wash arm, the connection adapter can be attached to the wash arm hub and exchanged for this wash arm.

The connection adapter can in particular have at least one fluid line for at least one cleaning fluid. This at least one fluid line can for example be formed or received in at least one base body of the connection adapter.

The connection adapter can in particular extend from the wash arm hub to a rear wall of a cleaning chamber of the dishwasher when it is installed in the dishwasher. For example, the connection adapter can be essentially S-shaped, with one end of the S being connected to the wash arm hub and an opposite end to the washing basket.

With the proposed game system and the proposed method, safe and reliable drying can be ensured within the dishwasher, even with items to be cleaned that are otherwise difficult to dry, such as bottles with a narrow neck. At the same time, additional handling steps can be avoided, such as removing the washing basket with the items to be cleaned after the cleaning fluid has been applied in the dishwasher and transferring them to a drying cabinet. These advantages can be realized in particular by a simple additional fan in or on a door of the dishwasher. An air duct of the blower can dock to a corresponding duct in the washing basket, which can be designed as a bottle basket, for example. A check valve can, for example, separate rinsing liquid and drying air. Alternatively or additionally, a further channel can be provided in the washing basket, which is provided exclusively for the drying gas, for example the air. The fan can, for example, be supplied with power through the door by means of a cable, or else, for example, inductively or by means of at least one energy storage device such as an accumulator. As an alternative or in addition to a fan in the dishwasher, an external drying unit, for example a compressor, can also be used, and an air line can be routed from there through a wall of the cleaning chamber to the connection adapter and / or to the washing basket. In general, at least one valve, for example, can be provided in the connection adapter, which valve selects, for example, a switchover between pressurized gas and / or pressurization with cleaning fluid. For example, this valve can comprise at least one air flap and / or a switchover valve. In this way, the connection adapter can, for example, participate in a pressurized gas supply to the washing basket.
