Description

Cleaner cartridge for cleaning device in ovens

The invention relates to a cleaning cartridge for cleaning a soiled interior of a device, in particular a furnace or steamer. The invention also relates to a device with such a cartridge and the

Use of such a cleaner cartridge in a process for cleaning such equipment.

DE 10 2006 025 508 A1 relates to a cleaning system for cleaning a baking or combi steamer device. In the baking / cooking space are filled with liquid and / or to liquid form prepared cleaning agents filled or fillable

Dispenser container positioned. The dispenser containers are each connected via a pipe and controlled by a control device regulating units to a compressed air and / or pressurized water supply line. The dispenser containers are connected in each case via an exit tube with the baking / cooking space. A arranged under the baking / cooking space drain tank is connected via a pipe and a circulating pump with at least one housed in the oven spray head.

Disadvantage of this solution is a cumbersome handling and the restriction to liquid cleaner. A solids cleaner must be transferred outside the cooking chamber and outside the cartridge manually by dissolution into a liquid product. Only then can a dispensing container be inserted into the cooking chamber and the liquid product released from the dispensing container and distributed by means of further, fixedly mounted in a cooking appliance or oven devices to be mounted, such as a fan or a nozzle.

US 2010/0072188 A1 has a cooking appliance to the object. An enamel coating containing a phosphate-based additive is placed on an interior

Surface, which limits a cooking chamber, applied. The inner surface of the cooking chamber is cleaned in such a way that high-temperature cleaning water is used. This allows effective cleaning of the walls of the cooking chamber. WO 2008/032138 A1 has a washing device to the object. The washing device is particularly suitable for cleaning chambers of various devices for industrial and household applications. The washing device essentially comprises a rotational body which is made of disc-shaped

Is constructed elements that are housed on a bearing bush. About the bushing, the washing fluid is supplied. The disk-shaped parts are shaped such that when they are exposed to the washing fluid, a number of rotating washing jets are directed at different impact surfaces and also impact the surfaces of objects. The complex structure of the washing device described herein and their complex fluid management make this washing device very sensitive to clogging by dirt particles or poorly soluble detergent components, which can lead to a concomitant blockage of rotation.

EP 1 582 265 A2 has a dispenser apparatus for the subject. A collecting body collects fluid to be dispensed, which is distributed via a suitable rotor. This static rotor is connected to the collecting body by a rotary coupling, wherein the collecting body is designed such that it receives on its inside an essential part of the body of the rotor. The rotary coupling parts comprise fastening means with a sealing disc, which are located between the rotor and the collecting body.

Another disadvantage of this solution is the complex structure of the one

Dispenser container and a rotation body comprehensive arrangement. Furthermore, the nozzles are sensitive to dirt due to the small diameter and tend to constipation in dirty washing liquor or use of solid cleaners. For this reason, the use is limited to liquid products in classic spray and rinse process for oven cleaning.

The object of the present invention is to provide a simplified cleaning system for appliances, in particular for the heat treatment of food, which is simple in design as well as in handling. So should be ensured by as few additional built-in service friendliness and failure-prone parts should be reduced or be exchangeable as a disposable component. Furthermore, a high degree of hygiene is to be achieved without loose dirt particles must be removed manually. According to the invention, a cleaner cartridge is proposed for cleaning a soiled interior of a device, in particular for heat treatment of foods, in particular a furnace or a steamer for heat treatment of foods, such as a steamer, wherein the purifier cartridge comprises:

a one-piece housing for receiving a treatment agent, at least one receptacle for connecting the cleaner cartridge to a

Water supply, wherein on the recording water at a pressure in the housing can be introduced, which allows spraying of a treating agent mixture, and - at least one spray opening for spraying the treating agent mixture, wherein the at least one spray opening is arranged as a rotation opening on the circumference of the housing such that the Cleaning cartridge is set in the spraying of the treating agent mixture in rotation. In particular, the cleaner cartridge is designed such that the cleaning of the soiled interior of the device takes place without further nozzles. A nozzle refers to a separate component with a narrowing

Conductor cross section in which a flowing medium, such as

Treatment mixture, in particular a cleaning solution, his

Speed increases with simultaneous pressure drop. By a one-piece design of the housing with the receptacle for the water supply and the arrangement of spray openings, the treating agent mixture is provided in a single component directly for spraying. The cleaner cartridge is thus directly to the particular without additional nozzle or nozzle device

Can be used for cleaning and thus provides an all-in-one solution for a cartridge with integrated nozzle unit, which also has a flexible construction of the

Cleaning system allows. Furthermore, no additional installations, such as additional nozzles and nozzle lines, are necessary in the device, whereby the number of components susceptible to failure is minimized. In addition to the simple construction, the cleaning cartridge is also user-friendly, since the nozzle and the

Treatment agent supply are combined in a single component. Thus, before the cleaning process, the cleaner cartridge can be inserted into the device and the Operation can be started, which allows easy handling by the user.

In the present context, a cleaner cartridge refers to a cartridge, which is preferably inserted into the device before the cleaning process. In this case, the cartridge can be designed as a reusable cartridge, which before the

Cleaning process is filled with treatment agent and is used in the device. Alternatively, the cleaner cartridge may be formed as a disposable cartridge, which is already filled with treatment agent and used before each cleaning process. Depending on the configuration, the cleaner cartridge can thus store enough treatment agent for one or more cleaning operations.

In one embodiment, the cleaner cartridge is a reusable or

Disposable cartridge designed with a sufficient amount of treatment agent for at least one cleaning process and preferably for a single

Cleaning process stored. For example, the cleaner cartridge may have a filling volume of 25 ml to 500 ml, preferably from 50 ml to 450 ml and more preferably from 75 ml to 300 ml. Thus, the volume of the housing may be selected such that treatment agent can be accommodated for exactly one cleaning process. The need for treatment depends on the length of the cleaning process and the volume to be cleaned.

Furthermore, the housing of the cleaner cartridge can be designed as a plastic housing. Such housing may, for example, a plastic such as polyvinyl chloride (PVC), polyethylene (PE), in particular slightly branched

Polyethylene (High Density Polyethylene, HDPE), Polypropylene (PP),

Polytetrafluoroethylene (PTFE), polyamide, polystyrene, polyurethane,

Polyethylene terephthalate or mixtures thereof. Preferably, the housing is made of a plastic, which is not attacked by the stored in the housing treatment agent. Furthermore, the housing is made of a plastic which is resistant to the temperatures prevailing during the cleaning cycle. Typical temperatures are 30 ° C to 100 ° C, preferably 50 ° C to 90 ° C, and most preferably 60 ° C to 85 ° C. Alternatively, the

Housing the cleaner cartridge designed as a metal housing.

The treatment agent may contain, for example, a cleaning agent and / or a descaling agent. As a cleaning agent are particularly suitable alkaline cleaning agents which have a pH of> 7, preferably between 9 and 13 in aqueous solution. Frequently used components of alkaline detergents are, for example, alkali metal hydroxides, alkali metal carbonates, phosphates, silicates, peroxides, percarbonates, methylglycinediacetic acid (MGDA), phosphates, polycarboxylates, enzymes or mixtures thereof. In addition, you can

surface-active substances, such as surfactants, emulsifiers or inhibitors are used. Common descaling agents may be, for example, citric acid,

Methanesulfonic acid (MSA), sulfamic acid, malic acid, maleic acid, tartaric acid, acetic acid or mixtures thereof.

Furthermore, the treatment agent can be taken up as granules, as a powder, as a gel, as a block, as a tablet or in liquid form in the housing. Preferably, the treating agent is as a tablet, granules, powder, block or gel in the

Housing added to not inadvertently, for example, during the

Transports can escape through the spray holes. Furthermore, the openings may be closed, for example with a peelable film, a tear-able film of a few μιτι, or a water-dissolvable film.

Furthermore, the openings may be closed with a wax that melts at a certain temperature. So can the treatment agent

be released temperature controlled. Alternatively, the openings may be closed by a water-soluble saccharide.

In a further embodiment, the receptacle can be designed as a fixed or rotatable receptacle. Preferably, the receptacle is designed for coupling the cleaner cartridge to a cleaning system of the device. Thus, the inclusion of a closure, such as a screw cap or a

Bayonet lock. For example, with a fixed

Receiving the cleaner cartridge a connection element of the cleaning system can be designed to be rotatable. Conversely, the inclusion of the

Reiniger cartridge be rotatable and the connection element of the

Cleaning system be stationary.

In another embodiment, the housing is cylindrical with a

Peripheral surface, a cartridge head and a bottom executed. The

Base of the cylinder can take any shape, such as round or square. In this case, an angular, in particular a rectangular shape or a housing in the form of a spray arm has the advantage that given a volume compared to a round shape, a greater distance to the axis of rotation and the greatest proximity to the side walls to be cleaned can be achieved. As a result, a stable rotation and a good cleaning result can be achieved. The receptacle can be arranged on the cartridge head of the housing. At an opposite bottom of the housing, the housing may be closed or at least one spray opening may be disposed on the underside of the housing. By the opposite arrangement of the receptacle and the spray openings is achieved that, for example, water is introduced to dissolve the treatment agent on the recording in the housing during operation and thereby increases the pressure within the cartridge so that the

Treatment mixture is sprayed through the spray holes.

To generate a rotational movement, the spray openings designed as rotation openings can be deformed inward in the direction of the tangential or inclined as a recess so that the spray openings

Spray treatment mixture in tangential direction. In a further embodiment, at least two rotational openings are arranged on the peripheral surface of the housing such that two tangentially directed jets with opposite spraying direction are produced during spraying. The

Rotary openings are designed such that in a rotatably mounted cleaner cartridge by the spraying of treating agent mixture the

Cleaner cartridge is placed in a rotary motion. Alternatively, a rotational opening may be sufficient if the torque generated by the removal of the outlet opening to the pivot point rotational movement of the

Reiniger cartridge initiated. It is advantageous, for example, to provide one, two or three openings which, in comparison to, for example, more than three openings, can be dimensioned larger in order to spray a corresponding volume flow. Due to the larger diameter they are not so easily clogged by dirt particles.

In a preferred embodiment, the spray openings are in one

arranged at regular intervals on the peripheral surface of the housing; Particularly preferably, two spray openings on the peripheral surface of the housing are arranged opposite one another, which set the housing of the cleaner cartridge in rotation of the spray jets of the treating agent mixture in rotation. In another embodiment, rotational bodies can be arranged on the peripheral surface of the housing, which support a rotational movement of the cleaner cartridge. In particular, the rotation bodies are arranged opposite one another and comprise spray openings which serve as rotation openings and generate the rotation of the housing. In this case, the spray openings can be arranged on opposite sides of the two bodies of revolution, in order to produce a spray jet in the opposite direction and so

To initiate rotation of the housing. By the rotary body, the spray holes can be arranged on the rotating bodies and the volume of the cleaner cartridge is not by a bevel of the

Reduced peripheral area. In addition, the distance from the fulcrum is increased and thus higher torque is achieved with respect to spray orifices integrated into the peripheral surface of the housing. In a further embodiment, additional spray openings may be arranged on the peripheral surface of the housing, the underside of the housing and / or on the rotational bodies, which have a smaller diameter than the spray openings, which cause the rotation of the housing. Preferably, the additional spray openings are designed as holes in the peripheral surface of the housing. Due to the additional spray openings, the mechanical

Abtragung of dirt particles supported to reach problematic areas of the room to be cleaned.

In another embodiment, within the housing is a

Retaining device, such as a collecting sieve arranged. The built-in restraint allows the cleaner cartridge to form a strainer for cleaning systems with a cleaning solution return loop, which is removed along with the cleaner cartridge. There are no

additional measures necessary to remove the dirt particles after

Cleaning process to be cleaned from the interior of the device to be cleaned. In addition, it is possible to dispense with a sieving device installed in the device or parts thereof. For example, it may be sufficient to provide a coarse sieve in the device which retains coarse food particles, such as bones, which could block a pump.

Preferably, a pump may be clocked. Thus, the retention device in the cleaner cartridge released by a return of dirt particles and it is possible to make the sieve area smaller in relation to the amount of dirt particles. If, for example, during the cleaning process, a pump such as a circulating pump clocked, for example, every 20 seconds, operated so that is not pumped in pauses about 5 seconds, runs the

Dirt from the restraint located within the cleaner cartridge in the line system of the cleaning system or on the bottom of the interior of the device, if no backflow prevention device is present. This leads to a return flow of dirt particles, causing the

Retaining device, as the collecting strainer, again free from dirt. Thus, even with high contamination of the device still pumping through the relative to the amount of dirt small dimensioned screen surface is possible. A floating in the device on the ground dirt can when pumping after the

Drain cleaning process into the drain. Only particles on the wall and ceiling of the device are not pumpable. The deposition of detached particles on these surfaces is, however, by the Auffangsieb in the

Cleaner cartridge prevented. In a further embodiment, in addition to the retaining device, a backflow prevention device is additionally arranged inside the housing, in order to prevent the backflow of dirt particles into the cleaning system. For example, a

Non-return device comprise a built-in in the cleaning system of the device check valve. In the interior of the device and

In particular in the cleaner cartridge, the backflow prevention device can also be realized as a dirt trap through a membrane, which occurs during the

Backflow of the treatment mixture closes. This ensures that dirt particles are collected within the cleaner cartridge and are completely decoupled from the cleaning system after removal of the cleaner cartridge. This allows the hygienic conditions in the

Cleaning system can be improved. Further according to the invention, a device, in particular for heat treatment and very particularly a steamer or an oven, proposed with a cleaning system, wherein in an interior of the device to be cleaned means for receiving the above-described

Cleaner cartridge are provided.

Connection element of the cleaning system to be coupled to a water supply. Preferably, the receptacle is connectable to the connection element of the cleaner cartridge described above. In particular, the above described cleaner cartridge provided in the interior to be cleaned, wherein the receptacle is coupled to the connection element.

Depending on the configuration of the cleaner cartridge, the device, in particular an oven, such as a steamer, a cleaning system of different design include. Preferably, the cleaning system of the apparatus comprises at least one water supply to convey water under pressure into the purifier cartridge and a drain line to either dispose of water from the interior or to recycle water via a return line.

The water supply can be provided via a fresh water pipe or a tank in the device. For transporting the water in the cleaner cartridge, a pump may further be provided, the water about from the tank or from the fresh water line via lines of the cleaning system in the

Carried cleaner cartridge.

In a further embodiment, the connection element is rotatable or static. For example, if the cleaner cartridge contains a static

Connecting element, the connection element of the cleaning system, to which the cleaner cartridge is coupled, rotatably, for example, with a rotor configured. Conversely, if the cleaner cartridge includes, for example, a rotatable connection element, the connection element in the cleaning system, to which the cleaner cartridge can be coupled, can not be made rotatable. Furthermore, a drain can be provided with a sieve in the interior of the device to collect dirt particles and keep away from the cleaning system. This sieve catches the dirt particles and can after the

Cleaning process to be emptied. In one embodiment, the cleaner cartridge can be arranged laterally, above or below in the interior of the device. Preferably, the cartridge is arranged in a central region of a lateral, upper or lower of a wall bounding the interior of the device to the largest possible

On the one hand, the inner annular gap 63 ensures sufficient radial clearance, so that the receptacle 50 can rotate about the bearing journal 66; on the other hand, the formation of an inner annular gap 63, as shown in FIG. 4C, enables the formation of a fluid film. This, during operation of the cleaning system adjusting fluid film between the

Inside the plane surface 65 of the receptacle and the top of the annular support surface 67 on the bearing pin 66 and the inner annular gap 63 reduces the friction and thus acts as a sliding bearing.

FIG. 4C further shows that an annular contact surface 67 extends at the end of the bearing journal 66, which is located in the receptacle 50. From the illustrated in Figure 4C, the fluid flow symbolizing arrows shows that through the inner annular gap 63 from the interior of the cleaner cartridge 14 via the support surface 67th and the above this annular gap 63, fluid can reach the flat surface 65 of the receptacle 50.

It can also be seen from the representation according to FIG. 4C that at least one fluid passage opening 69 can be located on the bearing journal 66, at whose lower end the bearing surface 67 is located. By this, the formation of a fluid film on the top of the flat surface 65 of the receptacle 50 and between the top of the annular support surface 67 and the underside of the flat surface 65 is supported. Figure 4C also shows the

Flow conditions that adjust above the support surface 67 at the lower end of the journal 66 and by the provision of the fluid passage opening 69 in the lateral surface of the journal 66.

FIGS. 5A and 5B show a third embodiment of a cleaner cartridge 14 with rotational bodies 70. FIG. 5A shows a plan view of the invention

Cleaner cartridge 14 and Figure 5B is a side view of the cleaner cartridge 14. The illustrated in Figures 5A and 5B third embodiment is with the in this embodiment, an external thread having receptacle 50 in one of the Ceiling of the interior 28 of the device 10 to be cleaned, screwed, for example, a steamer or oven located threaded portion.

In particular, the rotary bodies 70 are designed with a triangular cross-section, wherein the rotary bodies 70 have a straight side 72 in the direction of rotation 60.

Furthermore, one side 74 is configured obliquely. The spray openings 54 are arranged in the straight side 72 of the rotary bodies 70.

FIG. 5B shows a side view of the cleaner cartridge 14, which comprises a receptacle 50 which is attached to the connection element 32 of the supply line 20 of FIG

Cleaning system 12 is attached. Furthermore, the receptacle 50 is designed as a screw head, wherein in the receptacle 50, the pivot bearing 76 is introduced.

The cleaner cartridge 14 includes spray openings 78, 80, 54 in different areas and with different sizes at the periphery 44 of the housing 42. The spray openings 78 are provided in a tapered portion 82 of the housing 42 within which the circumference of the housing 42 for receiving 50 decreases , The spray openings 78 serve for the targeted spraying of dissolved treatment agent mixture 61 to the top of the housing 16 in the interior 28 of the device 10 to be cleaned, for example a steamer or a furnace, as shown in Figures 1 and 2. In the central region 56 of the housing 42, two types of spray openings 80, 54 are provided. The spray openings 80 serve to uniformly wet the side walls of the housing 42 of the interior 28 of the device 10 to be cleaned, for example a steamer or a furnace, as shown in Figures 1 and 2. The spray openings 80 have compared to the rotational movement of the housing 42 enabling spray openings 54 of smaller diameter and are embedded in the peripheral surface of the housing 42. This creates the

Spray orifices 80 a higher discharge speed and a higher pressure and thus a better mechanical removal on the wall of the device 10 to be cleaned, for example a steamer or a stove.

As a result, dirt deposited there is removed more effectively. This effect can also be increased by further spray openings (not shown), which can be arranged on the rotational bodies 70 opposite to the direction of rotation and have a smaller diameter than the spray openings 54. Through this

Arrangement, the resulting ejection speed of the spray jets of the treatment mixture 61 is further increased, which further improves the mechanical removal action of the spray jets on surfaces. On the other hand, however, the small volume flow of the angular momentum of the spray openings 54 hardly

weakened.

The spray openings 54 are arranged in the rotational bodies 70 and additionally generate the rotational movement. By spraying dissolved

Treatment agent mixture 61 from the spray openings 54 becomes a

Rotational movement generates the cleaner cartridge 14 in a

Rotational movement offset in the direction of rotation 60.

In addition, the cleaner cartridge 14 shown includes a catcher screen 40 inside the housing 42. This retains debris so that only

Treatment agent mixture 61 or cleaning solution can pass through the collecting sieve 40 and can exit via the collecting sieve 40 into the interior 28 of the device 10 to be cleaned, for example a steamer or a furnace. A

Membrane 41 or a dirt trap 84 at the inlet of the cleaner cartridge 14 prevents the backflow of dirt particles and treatment agent mixture 61 back to the pump 22 and water supply 20, in particular when the pump 22 is operated clocked.

FIGS. 6A and 6B show a fourth embodiment of the cleaner cartridge 14 with rotational bodies 70.

FIG. 6A shows a top view of the cleaner cartridge 14 with rotational bodies 70. The rotary bodies 70 are mounted on opposite sides of the cleaner cartridge 14 on the periphery 44 of the housing 42. The

Rotary bodies 70 have a vane shape, wherein in each case one-sided spray openings 54 are mounted in the direction of rotation 60 on the rotating bodies 70, from which dissolved treatment-agent mixture 61 is sprayed. This will be a generates tangential force component, which causes a rotational movement 60 of the housing 42 about the pivot bearing 76 relative to the receptacle 50. The externally threaded receptacle 50 is in a threaded portion or a

Positive locking connection enabling latching at the top of the

Interior 28 of the device to be cleaned 10, such as a steamer or a stove rotatably received.

In Figure 6B, the cleaner cartridge 14 is shown in a side view. At the head of the cleaner cartridge 14, the receptacle 50 is provided, which allows the connection with the connection element 32 of the cleaning system 12. By the

Pivot 76 can rotate the housing 42 of the cleaner cartridge 14 relative to the stationary mounted receptacle 50. The rotary bodies 70 include the

Spray orifices 54, which spray the dissolved treatment agent mixture 61.

These serve both to generate the rotational movement of the housing 42 by the exiting spray jets, as well as for the application of

Treatment agent mixture 61 to be cleaned surfaces of the interior 28 of the device 10 to be cleaned, for example, a steamer or a stove.

In addition to the spray openings 54 on the rotating bodies 70 are more

Spray openings 80 in the central region 56 on the circumference 44 of the housing 42 is provided. Through these spray openings 80, the treatment agent mixture 61 in the interior 28 of the device 10 to be cleaned, for example one

Steamer or a stove, sprayed to dirt on the

The cleaner cartridge 14 further includes a catcher screen 40 within the housing 42 that removes debris from the returned, released one

Treatment agent mixture 61 collects. The dirt particles are from the

Retention screen 40 retained so that they are not redistributed by the spray openings 54, 80 in the interior 28. In addition, a clogging of the

Spray holes 54, 80 prevented. At the end of the cleaning process, with the pump 22 switched off, the dirt particles sediment on the bottom of the collecting screen 40, wherein the dissolved in the cleaner cartridge 14 dissolved

Treatment mixture 61 exits through the spray openings 54, 80 in the interior 28 and leaves it via the outlet 31. FIG. 6C shows a variant of the cleaning cartridge in which the

Recording and the bearing pin represent a component.

As can be seen from FIG. 6C, the bearing journal 66 and the receptacle 50 with the plane surface 65 form a component. The receptacle 50 trained with it

Bearing 66 is screwed, for example, at the top of the interior 28 of the housing 16 to the connection element 32 of the cleaning system and is thus taken there rotationally fixed. Along a support surface 67 which defines an outer annular gap 86, the housing 42, which the

Peripheral surface 44, relative to the stationary recorded recording 50 to rotate. Between the bearing surface 67 of the housing 42 and a projection of the receptacle 50, an outer annular gap 86 is limited.

In the embodiment shown in Figure 6C are the rotation of the housing 42 causing spray openings, which are not shown here, in the peripheral surface 44 and move the housing 42 about the pivot bearing 76 in rotation.

Figure 7 shows an alternative embodiment of the cleaner cartridge with a

Positive connection on the device to be cleaned, i. for example, the device 10 to be cleaned, for example a steamer or an oven.

As is apparent from Figure 7, the bearing pin 66 is traversed by water. The flow passes through the cartridge head 48, which has a fluid flow taper 92, into the interior of the housing 42 of the cleaner cartridge 14 which is bounded laterally by the peripheral surface 44. In this are the rotation of the housing 42 generating spray openings 54. Above it is located at the

Bottom 46 of the housing 42 of the cleaner cartridge 14 at least one further spray opening 52 through which the treatment mixture 61 in the interior 28 of the device to be cleaned O, for example, a steamer or a furnace, which is not shown here, exits.

The planar surface 65 of the housing 42 is wetted by a fluid film 90. This results from the fact that at the lower end of the bearing journal 66, a fluid guide 88 is executed, which is a partial flow of the bearing pin 66 passing

Water flow branches off and leads around the cartridge head 48, so that forms on the plane surface 65 said fluid film 90. This serves to reduce the friction between the housing 42 of the cleaner cartridge 14 relative to the latter Bearing on the journal 66. Also in the illustrated in Figure 7

Embodiment variant is for connection to the connection element 32 of the

Cleaning system 12 of the bearing pin 66, which may for example have an external thread in the top of the housing 16, i. the interior 28 of the device 10 to be cleaned, for example, a steamer or a stove, screwed and therefore stored stationary. In another embodiment, the cartridge head 48 of the cleaner cartridge can be inserted and secured directly in a fixedly mounted in the bearing journals. Due to the

Positive connection at the cartridge head 48 rotates the housing 42 relative to the stationary in the housing, or arranged in the interior 28, with the

Water supply connected trunnions 66.

In the proposed solution according to the invention is preferably used as a treatment agent cleaner in solid form, be it in tablet form, as a powder or granules or in Blockgform or in gel form, wherein the treatment agent within the cleaner cartridge 14 within the device only after the start of the cleaning cycle to a liquid treatment agent is dissolved by supplying H ₂ O. This represents a particularly convenient and safe application. In the solution proposed according to the invention, the cleaner cartridge 14 is equipped with at least one spray opening 54, which in addition to bringing about a rotation of the housing 42 of the cleaner cartridge 14 also targeted

Problem areas of the soiled interior 28 reached. The receptacle 50 allows a connection of the cleaner cartridge 14 before each

Cleaning cycle with the device to be cleaned 10, such as a steamer or an oven, wherein after the cleaning process, the cleaner cartridge 14 can be removed from the device 10 to be cleaned and disposed of.

Due to the fact that by the removal of at least one

Sprühöffnung 54 from the pivot point of the housing 42, the torque is maximized on the one hand and on the other hand, the maintenance of the bulk of the volume and thus the mass in the vicinity of the fulcrum, the counteracting the rotation inertia is minimized, even with relatively large volume

Detergent cartridges 14 a stable rotation can be achieved. Furthermore, the proposed solution according to the invention is characterized in that the at least one spray opening 54, the targeted spraying of the

Treatment agent mixture 61 allows for mechanical removal support. Thus, special spray openings 78 in the ceiling of the cleaner cartridge 14 and spray openings 52 may be provided, from the bottom 46 of the cleaner cartridge 14 to the bottom of the device 10 to be cleaned, for example, a steamer or a furnace, ie on the interior to be cleaned 28 limiting bottom are directed. A targeted spraying of the ceiling is useful, as well as a targeted spraying of the floor of the

Interior 28, since the bottom portion of the inner space 28 serves as a collection point for running off of the boundary walls of the interior 28 dirt, such as grease, oils or sugar and is a very difficult to clean area.

The cleaner cartridge 14 has a volume body with a volume which, depending on the application, is from 25 ml to 500 ml, preferably from 50 ml to 450 ml and particularly preferably from 50 ml to 300 ml.

Figures 8 and 9 show a variant of the cleaning cartridge in the form of a rotating spray arm.

As can be seen from the plan view according to FIG. 8, the cleaner cartridge 14 in the embodiment according to FIG. 8 is provided in spray arm mold 94. As a result, the spray openings 54, which ensure the rotational movement of the cleaner cartridge 14 in spray arm mold 94 about the bearing journal 66, are at a relatively large distance from the axis of rotation of the cleaner cartridge 14. The cleaner cartridge in the form of the spray arm 94 as shown in FIG. 8 has one Formed as a positive connecting element cartridges köpf 48, which is formed at the upper end of the journal 66. If the cartridge head 48 is inserted into the form-fitting receptacle 96 likewise shown in FIG. 8, the detergent cartridge 14 is connected to the supply line 20 of the cleaning system 12 on the one hand. On the other hand, the cleaner cartridge is able to

Sprüharmform 94 to rotate about the support surface 67, which, as shown in Figure 9 at the lower end of the positive connection at

Cartridge head 48 having bearing pin 66 is located. From the spray openings 54, which are located on the opposite longitudinal sides of the cleaner cartridge in Sprüharmform 94, the dissolved treatment agent mixture 61 emerges radially and puts the cleaner cartridge in Sprüharmform 94 in Rotation about the stationary mounted on the form-locking receptacle 96 bearing pin 66th

The illustrations according to FIGS. 10.1, 10.2 and 10.3 show a cleaner cartridge designed as a two-chamber cartridge.

In the two-chamber cartridge 98 shown in Figures 10.1 to 10.3 is a disposable cartridge, on the housing 42 arm-shaped rotary body 70 are arranged. As a result, the housing 42 of the two-chamber cartridge 98 is able to rotate about the bearing journal 66, which comprises a rotary bearing 76 (not shown here in greater detail). The bearing pin 66 is preferably provided with an external thread, which in a corresponding connection element 32 of the

Cleaning system 12 of the device 10 to be cleaned, for example, is screwed.

The illustration according to FIG. 10.2 shows that the two-chamber cartridge 98 designed as a disposable cartridge has a first, overhead chamber 100 and a second chamber 102, which is separate therefrom. On each of the arm-shaped rotary body 70 is located on opposite sides of the spray openings 54, on the loosened

Treatment mixture 61 exits and brings the housing 42 of the two-chamber cartridge 98 to the pivot bearing 76 about the bearing pin 66 to rotate.

Below the first chamber 100 is a second chamber 102, which is closed by a closure 104, which enables a retardant release of the present in the second chamber treatment agent or the present there treatment agent mixture. The closure 104, which closes an opening formed at the bottom of the second chamber, is preferably formed from wax or another substance which melts when the temperature increases or is better dissolved in a mixture of treating agents or water. Depending on the temperature prevailing in the interior 28 of the device 10 to be cleaned, the closure 104 melts or dissolves and releases the opening located on the underside of the second chamber 102, as shown in FIG. 10.3. As a result, the treatment agent stored in the second chamber 102 of the two-chamber cartridge 98 or the treatment agent mixture stored there enters vertically downwards into the interior 28 of the device to be cleaned, while the treatment agent mixture stored in the first chamber 100 exits through outlet from the located on the rotary body 70 spray openings 54 in the

Interior 28 of the device to be cleaned enters.

Due to the temperatures prevailing in the interior 28, a melting of the closure 104, which preferably melts from wax or another melting at a temperature increase or better in

Treatment mixture or water-dissolving substance is made possible, so that a delayed release of stored in the second chamber 102 of the two-chamber cartridge 98 treatment agent mixture can take place.

While the treating agent stored in the first chamber 100 is directly connected to the cleaning system 12, the second chamber 102 contains a different treating agent and has no connection to the first chamber 100. The treating agent contained in the first chamber 100 is released immediately after the program is started , the treatment agent mixture 61 is formed and enters via the spray openings 54 in the interior 28 of the device 10 to be cleaned. The release of the stored in the second, lower chamber 102 treatment agent then takes place when a desired temperature is reached, the melt formed by wax closure 104 melts and the product from the then released opening 106 in the vertical direction enters the interior 28 of the device to be cleaned ,

The device to be cleaned can be between the action phase of the first

Treating agent mixture from the first chamber 100 and the action phase of the second treatment agent mixture are rinsed out of the second chamber 102.

Such a two-chamber cartridge, for example, a first

Treating agents such as e.g. an alkaline cleaning agent in the first chamber 100 and another alkaline cleaning agent or an acid descaling agent in the second chamber 102 have. As a result, the device 10 to be cleaned can either be cleaned and decalcified within a cleaning program of the cleaning system 12 or deep-cleaned by two successive cleanings.
