Description
Technical Field
The present invention relates to a cleaning device, and a method of manufacturing a cleaning device. Cleaning devices and methods of the type described can be used, for example, in the field of care sector or hospital technology, for example, for cleaning containers, such as bedpans, for containing human waste. In this regard, the present invention is particularly useful for cleaning and sanitizing devices used in hospitals or nursing homes, single-chamber cleaners, such as cartridge cleaners, or conveyor dishwasher cleaners, such as flying and/or rack-type conveyor cleaners. Furthermore, a cleaning device of the type described can however also be used in dishwasher technology, in particular in the field of commercial dishwasher technology, for example as a single-chamber dishwasher or as a conveyor dishwasher. But other fields of application are basically possible.
Background
The prior art discloses a number of cleaning devices, also called cleaning units, which are capable of cleaning and/or sanitizing articles to be cleaned. The configuration of the cleaning device is entirely highly dependent on various frame conditions, such as the type of article to be cleaned, dirt, throughput or the like. For example, reference may be made to cleaning devices such as are described in DE 10 2004 056 052 A1 or DE 10 2007 025 263 A1.
Cleaning devices of the type described generally have at least one application device for applying at least one cleaning fluid to the items to be cleaned. For example, a nozzle system, particularly a cleaning system having one or more nozzles, may be provided for applying one or more cleaning fluids (e.g., liquid and/or vapor) to the article to be cleaned. Furthermore, at least one controller is typically provided which controls one or more functional components of the cleaning device, for example one or more pumps, one or more heaters, one or more valves, or the entire functional component group and its time sequence, including the entire cleaning procedure.
Especially in the case of cleaning and sanitizing devices used in hospitals or nursing homes, but also single chamber cleaning devices, such as tank cleaners, or other cleaning devices, such as conveyor cleaners, it is often necessary to orient the nozzles to allow a targeted application of cleaning liquid to the items to be cleaned. The direction of the nozzle is therefore usually set during the installation process, in particular by means of a thread, for example by means of the screwing depth of the thread. In many cases, the nozzle is secured in the desired orientation by means of a counter-retaining means such as a lock nut. However, it is often the case that the direction may be adjusted during the service life, for example due to material fatigue, mechanical influences (e.g. improper loading and/or overfilling of the cleaning device by the user) or due to other factors. A technical solution is therefore desirable which allows a simple, well-defined nozzle direction and preferably prevents the direction from being adjusted during the service life.
Disclosure of Invention
It is therefore desirable to provide a cleaning device and a method of manufacturing a cleaning device which at least to a large extent avoids the disadvantages of known devices and methods of the type described. In particular, the aim is to design the orientation of the nozzles so as to be simpler and more uniform.
The present invention relates to a cleaning device and a method of manufacturing a cleaning device, having the features of the independent patent claims. Advantageous developments which can be realized individually or in any desired combination are set forth in the dependent claims.
In the following, the terms "have," "include," or "comprise," or any grammatical variant thereof, are used in a non-exclusive sense. Thus, such an expression may refer to either a case where no further features are provided in addition to the features introduced by such an expression, or a case where one or more further features are provided. For example, the expression "a has B", "a contains B", or "a includes B" may refer to a case where no further elements are provided in a other than B (i.e., a case where a is entirely composed of B) and a case where one or more further elements are provided in a other than B, such as elements C, and D, or even more.
Furthermore, it should be noted that "at least one" and "one or more" and grammatical variants of such expressions, when used in conjunction with one or more elements or features and intended to mean that the element or feature may be provided separately or multiple times, typically only once, e.g., when features or elements are first introduced. When features or elements are referred to again later, the corresponding expression "at least one" or "one or more" is generally not used any more, without limiting the possibilities that the features or elements may be provided alone or in multiple.
Furthermore, the expressions "preferred", "particularly", "e.g." or similar expressions are used hereinafter in connection with optional features, without limiting alternative embodiments. Thus, the features introduced by these expressions are optional features and are not intended to limit the scope of the claims, particularly the independent claims, by way of these features. Thus, as will be appreciated by those skilled in the art, the present invention may also be implemented using other configurations. Similarly, features introduced by "in one embodiment of the invention" or by "in one exemplary embodiment of the invention" are to be understood as optional features, but are not intended to limit the scope of the alternative configurations or the independent claims.

Within the scope of the present invention, an "item to be cleaned" is generally understood to be any object that can be cleaned in a cleaning device. Here, one object may be cleaned, or a plurality of objects may be cleaned simultaneously or sequentially. In particular, the article to be cleaned may be a container for human waste, such as a urine bottle, a bedpan or the like. Thus, the cleaning device may for example be in the form of a so-called cleaning and disinfecting device. Or the items to be cleaned may be objects which are used directly or indirectly for preparing, storing or serving dishes, that is to say, for example, crockery, cutlery, trays, bowls, glasses, kettles, pans or the like. Thus, the cleaning device may also be in the form of a dishwasher, for example in the form of a dishwasher commercially used in a large kitchen or in the form of a catering kitchen. Other configurations of the cleaning device and/or the item to be cleaned are basically possible.
As used herein, "cleaning device" is a broad expression which, as understood by those skilled in the art, is to be given its ordinary and common meaning. This expression is not limited to a particular or compatible meaning.

Here, a single cleaning chamber may be provided, or a plurality of cleaning chambers may be provided substantially, for example, sequentially. For example, the cleaning chamber may have at least one opening for loading the cleaning chamber with the articles to be cleaned. For example, this may be an opening with a shutter arranged on the front side of the clean room and/or on the top side of the clean room. Alternatively, a hood for closing the cleaning chamber is also possible, for example in the context of a so-called hood-type cleaning machine, such as a hood-type dishwasher. Conversely, it is also possible to design the cleaning chamber as a tunnel, for example in whole or in part, in particular in the context of so-called conveyor cleaners, for example conveyor dishwashers.
The expression "nozzle unit" as used herein is a broad expression which, as understood by a person skilled in the art, is to be given its usual and common meaning. This expression is not limited to a particular or compatible meaning. The expression may, but is not limited to, particularly refer to any device configured to apply a cleaning fluid to an article to be cleaned in a defined manner. Thus, the nozzle unit may have at least one outlet opening through which cleaning fluid may flow out and may be applied to the item to be cleaned. For example, the nozzle unit may be in the form of a single nozzle or a combination of nozzles, and thus may also be referred to as a "nozzle". In particular, the nozzle unit may be configured to direct the cleaning fluid onto the item to be cleaned, for example in a preset direction or at a preset angle. Alternatively or additionally, the nozzle unit may also be configured to set a pressure, for example a force, with which the cleaning liquid is applied to the item to be cleaned. As will be discussed in more detail below, the nozzle unit comprises a nozzle element and a connecting element, and possibly also one or more other elements.
As used herein, the expression "cleaning fluid" is a broad expression which, as understood by those skilled in the art, is to be given its ordinary and common meaning. This expression is not limited to a particular or compatible meaning. The expression may, but is not limited to, in particular refer to any liquid and/or any gas designed for cleaning and/or sanitizing the items to be cleaned. In particular, the cleaning fluid may be designed to exert a cleaning action upon touching the item to be cleaned. For example, the cleaning fluid may comprise an aqueous liquid, such as water and/or water containing one or more additives, such as one or more cleaner concentrates and/or rinse aids and/or disinfectants. The cleaning device may be configured to use a single cleaning liquid or to use a combination of cleaning liquids. Alternatively or additionally, the cleaning fluid may comprise, for example, a gas, such as steam, which heats a liquid. If several cleaning fluids are provided, different cleaning fluids may be applied to the article for cleaning simultaneously or sequentially. Thus, the items to be cleaned can for example remain stationary in the cleaning chamber and different cleaning fluids can be applied to them continuously.
In the context of the present invention, the expression "pore" is generally understood to mean any shaped pore and/or pore size. For example, the aperture may in particular have a substantially circular shape, such as a circular aperture. For example, the hole may have a circular opening with a protrusion or recess parallel to the axis of the hole. In particular, the "hole in at least one wall of the cleaning chamber" may comprise, for example, an opening through the cleaning chamber, for example through the housing of the cleaning chamber, wherein the nozzle unit extends through the hole, in particular the hole in the cleaning chamber wall, and is for example connected to the supply conduit. The expression "feed line pipe" as used herein is a broad expression which, as understood by a person skilled in the art, is to be given its usual and common meaning. This expression is not limited to a particular or compatible meaning. The expression may, but is not limited to, particularly refer to any conduit that directs and/or directs a fluid. The supply conduit may be particularly configured to direct or channel a fluid, such as a cleaning fluid, from, for example, a tank or container into the cleaning chamber.
The expression "connecting element" as used herein is a broad expression which, as understood by a person skilled in the art, is to be given its ordinary and common meaning. This expression is not limited to a particular or compatible meaning. The expression may, but is not limited to, particularly refer to any element configured to be connected to at least one further element to enable a fluid connection. The connection element may be configured to be connected to a supply conduit, for example, in order to transfer fluid guided in the supply conduit into the connection element, for example. In particular, the connection element, for example of the nozzle unit, may be arranged at least partially outside the cleaning chamber wall.
The expression "nozzle element" as used herein is a broad expression which, as understood by those skilled in the art, is to be given its ordinary and common meaning. This expression is not limited to a particular or compatible meaning. The expression may, but is not limited to, particularly refer to any element and/or object as an integral part of the nozzle unit such that the cleaning fluid can flow out of the nozzle unit such that the cleaning fluid can be applied to the article to be cleaned. The nozzle element may in particular be configured to influence at least one flow characteristic of a fluid (e.g. cleaning fluid), in particular a speed, a flow direction, a pressure and/or a force. For example, the nozzle element may be configured to change the flow direction of the cleaning fluid flowing through the supply conduit and the connection element connected to the supply conduit. In particular, the nozzle element may be arranged, for example, in the cleaning chamber, for example on the inner side of the cleaning chamber wall, opposite the outer side.
The expression "in a rotationally fixed manner" as used herein is a broad expression which, as understood by a person skilled in the art, is to be given its usual and common meaning. This expression is not limited to a particular or compatible meaning. The expression may, but is not limited to, in particular refer to a limited possibility of rotational movement between any two objects. For example, the rotational fixation may be formed by at least one form fit. For example, the form fit may be formed in particular by the respective shapes of the two objects. In particular, the bore and the nozzle unit may be shaped, for example complementarily shaped, in particular in terms of their shape, such that the nozzle unit is rotatably fixed in the bore. Alternatively or additionally, a positive fit or friction engagement may also be rotationally fixed.
In particular, the nozzle unit held in a rotationally fixed manner in the bore may have, for example, a first fixing element and the bore may have, for example, a second fixing element. In particular, the first fixing element may engage into the second fixing element at a preset rotational angular position of the nozzle unit about the axis of the bore. For example, the nozzle unit may be held in a rotationally fixed manner in the bore by the interaction of a fixing element, e.g. a first fixing element and a second fixing element. For example, the first and second fixing elements may engage with each other, in particular according to the key lock principle.
The expression "key lock principle" as used herein is a broad expression which, as understood by a person skilled in the art, is to be given its usual and common meaning. This expression is not limited to a particular or compatible meaning. The expression may, but is not limited to, in particular refer to the principle or function of operation based on the assembly of two or more complementary structures. In particular, the key lock principle may be a working principle based on the geometric or spatial assembly of at least two structures or elements together. For example, if the shape, e.g., geometry, of one of the two elements corresponds, in whole or in part, to the negative shape of the other element, the two elements may interact or one element may engage the other element in accordance with the key lock principle.
With respect to the fixation elements, and in other connections, the expressions "first" and "second" and further expressions of similar nature are used as terms, without in this way predefining sequences or orders of importance. Furthermore, a plurality of "first" or "second" elements may be provided.
In particular, the first fastening element may engage into the second fastening element according to the key-lock principle, for example at a preset rotational angle position of the nozzle unit with respect to the axis of the bore. For example, the first fixing element may comprise an element selected from the group consisting of a circumferential projection on the nozzle unit and a circumferential groove in the nozzle unit. In particular, the second security element may comprise in each case a complementary element of the set, for example of an element consisting of the first security element. In this regard, for example, a mating groove may be considered a complementary element for a projection, wherein the projection in the mating groove may engage in a form-fitting manner, and vice versa. Thus, for example, the first fixing element may have at least one recess and the second fixing element may have at least one projection which can engage in a form-fitting manner into the recess. Alternatively or additionally, the second fixing element may have at least one recess and the first fixing element may have at least one projection which can engage in the recess in a form-fitting manner. Alternatively or additionally, the first or the second fastening element may also comprise at least one wrench flat or three-surface arrangement, for example.
The nozzle unit may also have an adapter. In particular, the adapter may, for example, fix the nozzle element to the connecting element. For example, the adapter of the nozzle unit may be configured to fix the nozzle element to the connection element. For example, the adapter may be arranged between the nozzle unit and the connecting element in a similar manner as the intermediate piece.
In particular, one of the elements selected from the group consisting of the connecting element, the adapter and the nozzle element may be rotatably fixed in the bore. For example, the rotationally fixed retention of the nozzle unit in the bore may be achieved by means of elements, for example by means of connection elements, adapters and/or nozzle elements.
For example, the adapter and the connecting element may form a mounting unit. In particular, the mounting unit may alternatively or additionally also be held in a rotationally fixed manner in the bore. For example, a rotationally fixed retention of the nozzle unit in the bore may also be achieved by the mounting unit. In particular, the mounting unit and the aperture may interact, for example, according to the key lock principle.
In particular, one of the two elements selected from the group consisting of the connecting element and the adapter may be inserted in a rotationally fixed manner into the hole. For example, the other of the two elements may be screwed in particular to the first element on the other side of the wall. For example, the adapter may be inserted into the hole in a rotationally fixed manner, in particular from one side of the wall, and the connecting element may be connected to the adapter from the other side of the wall, in particular from the opposite side, for example by a screw connection, in particular screwed onto the adapter. Furthermore, it is also possible, for example, to insert the connecting element into the bore in a rotationally fixed manner, wherein the adapter can be screwed onto the connecting element from the other side.
The nozzle element can in particular be inserted into the mounting unit by means of snap fasteners. For example, the snap fastener may have a locking mechanism. In particular, for example, the nozzle unit may be insertable into the mounting unit in such a way that the snap fastener locks.
In particular, for example, the nozzle element may be axially fixed, in particular prevented from axial movement, for example by snap fastening or fastening. Thus, the snap fastener may be configured to absorb both forces acting on the nozzle element from the outside and internal forces, in particular forces acting on the snap fastener from the cleaning fluid, for example forces resulting from the flow and/or pressure of the cleaning fluid. The locking mechanism may be formed, for example, by the shape of the component and the elasticity produced by the material. Quick connections to other additional components are also contemplated.
Other methods of axially fixing the nozzle element in the mounting unit are basically possible, for example fixing rings.
In particular, the nozzle element may be rotationally fixed in the mounting unit. For example, the nozzle element may be fixed in the mounting unit in a rotationally fixed manner such that there is a first rotational fixation between the mounting unit and the wall and a second rotational fixation between the mounting unit and the nozzle element. In particular, the nozzle element can be inserted into the mounting unit in a predetermined angular position. Furthermore, the nozzle element may be mounted in a rotationally fixed manner in the mounting unit.
The nozzle element and at least one element, for example an element selected from the group consisting of a connection element and an adapter, may interact according to the key lock principle.
For example, the nozzle element may have at least one nozzle base. In particular, the nozzle base may have at least one axial bore for guiding the cleaning fluid. The nozzle element may also have at least one nozzle head which is rotatably mounted on the nozzle base.
The nozzle unit may also have at least one sealing element for sealing the nozzle unit against the wall of the cleaning chamber. In particular, the sealing element may have a sealing ring, for example an O-ring. The sealing ring may in particular be mounted on the outside of the wall. For example, the sealing ring may be mounted outside the annular groove of the connecting element.
The cleaning device may in particular be selected from the group: single chamber dishwasher; a box-type dish washer; conveying type dish washing machine; a cleaning and sanitizing device for cleaning a container containing human waste.
In another aspect, a method of producing a cleaning device for cleaning an article to be cleaned is presented. The method comprises the following method steps. The method steps may in particular be performed in the order described, although another order may also be used. For example, one or more method steps may also be performed repeatedly. In particular, the method may comprise further, unexplained method steps.
A method of manufacturing a cleaning device for cleaning an article to be cleaned comprising:
