Description

The invention relates to a dishwasher having a rinsing space for receiving items to be cleaned rinsing and a arranged within the rinsing spray for applying to be cleaned items with rinse liquor, wherein the spray device has a rotatably mounted spray arm with two wings, each providing a Spülflottenkanal ,

Dishwashers of the type mentioned are well known from the prior art, which is why it does not require a separate documentary evidence at this point.

Dishwashers of the type mentioned above have a washing container, also called tub, which provides a washing compartment. In the intended use case, the washing container serves to receive items to be cleaned, which may in particular be crockery and / or cutlery.

For loading of items to be cleaned with rinsing liquor, that is to say process liquid, a spraying device arranged within the rinsing container is used, which typically has a plurality of spray arms rotatably mounted about a common axis of rotation. As a rule, there are two or three such spray arms within the washing container, which are arranged one above the other in the height direction of the dishwasher.

To supply the spray arms with rinsing liquor is a supply line, which is connected on the one hand to the spray arms and on the other hand to a circulation pump. In the intended use case, by means of the circulation pump, bottom of the washing container accumulating rinsing liquor is sucked and distributed to the spray arms for the purpose of loading the dishes.

According to a previously known from the prior art, conventional design, a spray arm has two wings, also called branches. These wings branch off from the axis of rotation of the spray arm and provide each spray and / or drive nozzles for Spülflottenabgabe ready. To supply the spray and / or drive nozzles corresponding Spülflottenkanäle are formed in the spray arm or the Sprüharmflügeln through which the circulated in the intended use case, the rinsing water out of the washing pump and is directed to the spray and / or drive nozzles of Sprüharms.

Spray arms of the type described above are structurally designed for the cleaning of heavily soiled dishes. In more heavily soiled items to be designed for a standard stain spray arms may not be sufficient for the desired result to be achieved cleaning result.

In order to address this problem, spraying devices have become known from the prior art, which have for the purpose of intensive rinsing on extra spray nozzles and / or in particular trained spray nozzles, such as rotating nozzles and / or the like. This known embodiment has the disadvantage that only at certain positions in the washing room a spatially limited improved cleaning is possible. The user therefore does not have the choice of storage location with regard to the items to be cleaned. It is on the user side therefore to pay attention to an exact placement of the dishwasher. In addition, the surface covered by additional nozzles for the purpose of intensive cleaning is for the most part comparatively small, but in any case limited, so that there is the danger, in particular with comparatively large items to be washed, such as casserole dishes and / or pots, that these only partially of the additional Nozzles are detected, so that the desired cleaning result is actually not achieved.

The DE 1174461 A discloses a dishwashing machine comprising a spray arm having two vanes, each providing a rinsing liquor passage, the rinsing liquor passage of the spraying arm vanes each having a closable chamber for receiving detergent.

Based on the above, it is the object of the invention to provide a dishwasher of the type mentioned, which allows in an improved manner intensive rinsing for cleaning even heavily soiled items.

To solve this problem, the invention proposes a dishwasher with the features of claim 1.

The dishwasher provided according to the invention has a spray arm with at least two wings. The rinsing liquor channel of a Sprüharmflügels according to the invention has a cleaning agent. If necessary, this serves to be equipped with cleaning agents, that is to say chemicals to support the cleaning action. Such cleaning agent placement takes place in addition to the already provided on the dishwasher side loading of detergent. The particular advantage of the construction according to the invention is therefore that in the Detergent uptake of Spülflottenkanals accommodated cleaning agent is additionally used, with a release of the cleaning agent on the Sprüharmflügel takes place directly on the items to be cleaned. This ensures effective use of cleaning agents and avoids unnecessary overdoses. In this case, an admission with the additional detergent takes place directly on the items to be cleaned, so far as an intensive cleaning takes place.

The embodiment of the invention is not limited to the number of Sprüharmflügel. There are provided according to the invention at least two Sprüharmflügel, one of which is equipped in accordance with the invention with a cleaning agent receiving. However, the embodiment of a spray arm with three Sprüharmflügeln is preferred, wherein one of these Sprüharmflügel is formed in accordance with the invention. According to this embodiment, two Sprüharmflügel be charged via a conventional Spülflottenkanal with wash liquor, which is equivalent to the proper operation of a known from the prior art Sprüharms with two Sprüharmflügeln. The rinsing liquor channel of the third Sprüharmflügels has the inventively provided cleaning agent, so that with respect to this Sprüharmflügels with optional placement of cleaning agent receiving detergent as a result of loading the Spülflottenkanals with rinse liquor on the Sprüharmflügel not only rinsing liquor, but rinsing and it discharged from the cleaning agent cleaning detergent is discharged ,

According to a particular proposal of the invention, a metering unit is provided which can be inserted into the cleaning agent receptacle. This embodiment facilitates the user-side handling. If necessary, the dosing unit can be removed from the detergent dispenser, equipped with detergent and then returned to the detergent dispenser. This facilitates a simple dosing and introduction of the cleaning agent into the receptacle provided for this purpose. In this case, the dosing unit in its geometric dimensions is preferably designed such that commercially available cleaning rod can fit into it

The dosing unit has according to a further feature of the invention a housing. This serves to receive cleaning agent, for which purpose a corresponding volume space is provided by the housing. The housing has on two opposite sides of the housing via an opening, wherein these openings cooperate with the volume space. In the intended use case, these openings allow a flow through the housing of the dosing unit with rinsing liquor, as a result, it can lead to a proper Reinigungsmittelaustrag. The dosing unit can preferably be used in two different positions in the cleaning agent receptacle. In a first position, the openings provided by the housing of the dosing unit are aligned with the rinsing fluid channel. In this position of the dosing unit, a passage of the dosing unit with rinsing liquor is possible, that is, a feeding of the Sprüharmflügels with rinsing fluid is fluidically permitted. In the second position of the metering unit, this is offset by 90 ° from the first position in the cleaning agent receptacle, in which position the closed housing sides come to rest in the flushing liquor channel. In this position of the dosing unit, the rinsing liquor channel is preferably closed in a fluid-tight manner, so that an entry of rinsing liquor into the rinsing liquor passage and thus a loading of the spray arm vane with rinsing liquor can not take place. According to this position of the dosing unit, only one rinsing liquor feed of the first two spray arm wings takes place, while the third spray arm vane is blocked for the rinsing liquor.

It is provided according to a further feature of the invention that the one of the two openings of the housing of the metering unit can be closed by means of a locking member. This can be configured, for example, as a pivotable trained flap.

This embodiment makes it possible to block the rinsing liquor channel even when the dosing unit is inserted into the rinsing liquor channel, that a feed of the rinsing liquor channel with rinsing liquor is basically possible, that is, if the housing sides equipped with the openings lie flush within the rinsing liquor canal come. This structural design makes it possible to differentiate manually between a permanent closure of the Spülflottenkanals one hand, and an opening of the Spülflottenkanals basically, in the second position by the locking member selectively opening or closing the Spülflottenkanals is possible, which is preferably done automatically.

The locking member cooperates according to a further feature of the invention with an actuator. This allows opening of the Spülflottenkanals by pivoting the locking member in its open position. When the actuator is not activated, the locking member is held in its closed position due to the rinsing fluid pressure prevailing in the spray arm, in which charging of the rinsing fluid channel can not take place.

By means of the construction according to the invention, it is altogether permitted, the Spülflottenkanal the to lock further Sprüharmflügels, that is to close. Thus, the Spülflottenkanal is either open or closed depending on the position of the locking member for rinsing. The spray arm can thus be operated either either in normal position with, for example, two Sprüharmflügeln or with a switched, for example, third Sprüharmflügel, that is, in the intended use, either only about two Sprüharmflügel rinsing or optionally via an additional connected Sprüharmflügel, for example, a total of three Sprüharmflügel Flushing delivered.

The feed of the other, for example, third Sprüharmflügels with rinse liquor is the intensive cleaning of items to be cleaned. Here, the particular advantage of the invention is that by means of the switchable Sprüharmflügels a complete coverage of the space provided by the washing container is reached, so there is no limitation to certain Spülraumzonen unlike the prior art. The user can therefore freely position items to be cleaned, and it is nevertheless ensured that this is achieved in its entirety by the rinsing agent dispensed via the rinsing arm.

The locking member is preferably designed as a pivotally arranged on the housing of the dosing unit flap. This has the advantage that the flap is held in inflowing rinsing liquor as a result of acting on the flap rinsing pool pressure by itself, that is, without additional measures in its closed position. In the standard operating state, the flap serving as a blocking member thus blocks the rinsing liquor channel of the further spray arm vane. To check the locking member in the open position, this is actively to pivot by means of the designated actuator. In this case, the actuator holds in the activation state, the flap serving as a locking member open, in which case rinsing fluid can flow into the rinsing fluid channel of the further Sprüharmflügels. As soon as the actuator is put out of action again, the flap moves back into its closed position due to the flushing bottle pressure acting on the flap.

The actuator is preferably a thermoactor, which triggers temperature-dependent. Thus, for example, an actuator can be provided, which triggers the wash liquor, for example, a temperature of above 60 ° C above a certain temperature. Below this temperature, the actuator remains in the untriggered position, that is, a pivoting of the locking member does not take place. Such a thermoactor is an actuator which is based on an expansion material, for example wax, which expands when the triggering temperature is reached or contracts again when the triggering temperature falls below it.

The above-described embodiment has the advantage that the actuator is automatically actuated during the flushing process. The cooperating with the actuator locking member is the Spülflottenstrom for the associated Spülarmflügel only from a predetermined temperature, that is, the release temperature free. The triggering temperature is preferably chosen so that it is not achieved when performing a standard cleaning program, so it comes only to a trigger when the user side such a rinse program is selected, which brings correspondingly high temperatures, as typically selected when it comes to cleaning heavily soiled items.

The temperature-dependent switching of the actuator brings several advantages. On the one hand, it is ensured that a loading of the further Sprüharmflügels only takes place when such a wash program is selected, which leads to corresponding high temperatures during the implementation. The further Sprüharmflügel therefore remains inoperative when the triggering temperature is not reached, which is the case either in standard washing programs or in individual Spülprogrammabschnitten also a Intensivspülprogramms. In this case, the connection in the rinsing process is automatic, so it requires no special user-side triggering. As a result, the additional water consumption caused by the connection of the further spray arm wing is reduced to a minimum and limited to carrying out an intensive cleaning. The additional amount of water possibly required by the connection of the further Sprüharmflügels is detected dishwasher-side for a stable pump running, for example, by the detection of the pump speed and fed in case of need.

The embodiment of a locking member of the type described above proves to be particularly advantageous in combination with the invention provided for cleaning agent receiving. Because of this construction is achieved in total that the optionally housed in the detergent receptacle of Spülflottenkanals cleaning agent is introduced into the rinse cycle only when the actuator takes place an activation of the Spülflottenkanals by pivoting the locking member. As a result, the additional cleaning agent present in the cleaning agent receiving means is thus activated only in the moment in which the intensive cleaning takes place by connecting the further Sprüharmflügels.

The blocking member preferably designed as a flap is arranged to close one of the openings of the housing of the dosing unit directly on the housing of the dosing unit. It is constructively achieved a very compact design, because the locking member is used in particular to keep the metering unit closed, whereby at the same time a closure of the Spülflottenkanals is reached, in which the cleaning agent receiving is formed, in which the metering unit is inserted with its housing. When the locking member is opened not only in the manner described above, the rinsing liquor channel is opened, also provided by the housing of the dosing unit volume space is accessible for flow with rinsing fluid, so that rinsing out of the dosing provided under certain circumstances cleaning agent can take place.

According to a further feature of the invention it is provided that the actuator is arranged within the housing. Also, this structural configuration advantageously results in a compact overall structure. The dosing unit includes as a central component both the locking member and the actuator. User error operations can be excluded in an advantageous manner.

According to a further feature of the invention, a co-operating with the spray arm locking device is provided. This serves to fix the spray arm in case of need in its position and set in a predeterminable position for a predetermined period of time. This provides the advantage that the spray arm can be set in at least one of its Sprüharmflügel in such a position that the Sprüharmflügel intensive feeds a certain area of the washing compartment for a predetermined period of time with washing liquor. It will take place in this way a supplementary intensive cleaning in this particular area of the washing up. Preferably, a plurality of different positions for such a fixing of the spray arm can be provided, so that also different areas of the washing compartment can be approached selectively and subjected by means of an extra charge with rinse liquor of an intensive cleaning.

The locking device according to a further feature of the invention has a locking means. This can be moved into the movement path described by the spray arm, preferably moved into it. As soon as the locking device is activated, the locking means extends and blocks the spray arm in its otherwise performed movement. It is achieved in this way, the already described above fixing the Sprüharms.

The locking means of the locking device may be a pin according to a feature of the invention. This preferably cooperates with a corresponding thereto designed stop on the spray arm. The spray arm can be approached almost to stop up to the locking pin, as a result, it comes to blocking the twisting movement of the spray arm, so this is fixed. As soon as the locking means is moved back into its starting position, the rotary movement of the spray arm is released again so that it can rotate again in a manner known per se.

The locking device is activated and deactivated by the control device of the dishwasher, that is to say the locking means moves into and out of the movement path described by the spray arm. This takes place in particular automatically at predetermined or predefinable times in the wash program sequence and in particular as a function of the selected wash program. If the user intends an intensive cleaning of one or more specific parts of the items to be washed, for example a heavily soiled pot, then this part or parts thereof are to be placed by him, for example, in a predetermined intensive washing area of the dishwasher. Within this range, the items to be washed are applied continuously and thus particularly intensively with rinsing solution when the locking device is activated and thus the spray arm is fixed in position. The position and / or extent of the intensive rinsing area can be identified by marking means for the user, for example by color markings on the rinsing basket or by means of lighting means.

According to a further exemplary embodiment, a plurality of intensive rinsing areas and, corresponding thereto, a plurality of locking means arranged at different positions in the rinsing room can also be provided. In this case, the user can select, for example via suitable input means before starting the program, in which area of a washing basket, for example in which quadrant, an intensive cleaning is to take place. The control device then activates the locking device in such a way that, depending on the selected region, a specific locking means is selected and moved into the movement path described by the spray arm at a predetermined time so that intensive cleaning of that region is effected.

The inventively provided further Sprüharmflügel, which has a locking member and a cooperating actuator can have to further improve the cleaning effect on specially trained nozzles. These nozzles may, for example, be rotating nozzles and / or multi-jet nozzles. With a view to the invention Incidentally, it is also possible to use a so-called satellite or pendulum spray arm as the spray arm, that is to say a spray arm which has a first base spray arm and a second spray arm pivotably arranged on it.

• - Die mit dem erfindungsgemäß ausgebildeten Sprüharm abgedeckte Intensivspülzone erstreckt sich nahezu über die gesamte Grundfläche des Spülbehälters, so dass es verwenderseitig gestattet ist, zu reinigende Spülgüter beliebig platzieren zu können. Im Unterschied zum Stand der Technik steht mithin nicht nur eine räumlich sehr stark eingeschränkte Intensivspülzone zur Verfügung.
• - Es ist im zuschaltbaren Sprüharmflügel eine Reinigungsmittelaufnahme vorgesehen, die zur optionalen Verwendung von zusätzlichem Reiniger, das heißt Reinigungschemie dient. Hierdurch kann direkt das intensiv verschmutzte Spülgut zeitversetzt zu dem aus dem Dosiergerät der Geschirrspülmaschine stammenden Reinigungsmittel mit Reinigungschemie beaufschlagt werden.

• - Verwenderseitig ist es gestattet, die Intensivspülzone durch einfaches Umstecken der Dosiereinheit zu deaktivieren. In diesem Fall wird ein dauerhafter Verschluss des Spülflottenkanals erreicht.
• - Die Verwendung eines Aktors und eines zugehörigen Sperrgliedes macht es möglich, die Intensivspülzone nur in entsprechenden Programmabschnitten mit Spülflotte zu versorgen. Somit können zum Beispiel die Programmabschnitte mit vergleichsweise geringen Temperaturen ohne Verwendung der Intensivspülzone mit weniger Wasser über die Standarddüsen der übrigen Sprüharmflügel mit Spülflotte versorgt werden.
• - Durch ein zeitweiliges Anhalten des Sprüharms mittels der dafür vorgesehenen Arretiereinrichtung kann ein vordefinierter Bereich des Spülraums zusätzlich intensiv gespült werden.
• - Für die Intensivspülzone werden keine zusätzlichen neuen Wasserwege benötigt, womit in einfacher Weise und kostengünstig eine ergänzende Gerätevariante auch im Sinne einer Nachrüstung durch Tausch des Sprüharms geschaffen ist.

With the embodiment according to the invention, the following advantages are achieved in particular:

• - The intensive scavenging zone covered with the spray arm designed according to the invention extends almost over the entire base area of the washing container, so that it is permitted on the user side to be able to place items to be cleaned in an arbitrary manner. In contrast to the prior art, not only is there a spatially very limited intensive flushing zone available.
• - It is provided in the switchable Sprüharmflügel a detergent receptacle, which serves for the optional use of additional cleaner, that is cleaning chemistry. As a result, the intensively soiled items to be cleaned can be applied to the cleaning agent originating from the dosing unit of the dishwasher directly with a delay time.

• - On the user side, it is permitted to deactivate the intensive rinsing zone simply by repositioning the dosing unit. In this case, a permanent closure of the Spülflottenkanals is achieved.
• - The use of an actuator and an associated locking member makes it possible to provide the Intensivspülzone only in appropriate program sections with wash liquor. Thus, for example, the program sections can be supplied with rinsing liquor at relatively low temperatures without using the intensive rinsing zone with less water via the standard nozzles of the remaining Sprüharmflügel.
• By temporarily stopping the spray arm by means of the locking device provided for this purpose, a predefined area of the washing compartment can additionally be intensively rinsed.
• - For the Intensivspülzone no additional new waterways are needed, which in a simple way and cost, a complementary device variant is also created in terms of retrofitting by exchange of Sprüharms.

1 shows a schematic perspective view of a washing container 2 an otherwise not shown dishwasher 1 , The washing container 2 makes a washroom 3 ready, which serves in the intended use of receiving cleaning items to be cleaned.

Inside the washing container 2 is a spraying device 4 arranged. This has a plurality of each rotatably arranged spray arms, in the illustrated embodiment, the better overview because of only the lower spray arm 5 the dishwasher 1 is shown.

The spray arm 5 has one at a middle part 12 arranged connecting piece 11. In the intended use case, the spray arm twisted 5 around one of the connecting piece 11 provided rotation axis. The spray arm 5 is equipped in the embodiment shown with three wings and has a first Sprüharmflügel 6 , a second spray arm wing 7 and a third spray arm wing 8th , each starting from the middle part 12 extend radially outward. The two spray arms 6 and 7 are equipped as standard spray wings and have in a conventional manner via spray nozzles 9 , via which, in the intended use, rinsing liquor is dispensed for the purpose of loading items to be cleaned.

The spray arm according to the invention 5 has another spray arm wing 8th who is trained as follows:

The spray arm wing 8th provides a rinse liquor channel 13 ready, above that in the intended Use case rinsing liquor in the Sprüharmflügel 8th arrives. The from the spray arm wing 8th provided spray nozzles 10 are thus supplied with rinsing liquor, which is in the embodiment shown in the spray nozzles 10 around rotating trained spray nozzles 10 is.

The rinsing liquor channel 13 is with a cleaning pickup 14 equipped, as can be seen in particular from the illustration 2 results. In the intended use case is in the detergent 14 a dosing unit 15 used. This dosing unit 15 has a housing 16 that has a volume space 17 Are defined. This volume space 17 is used in the intended use of the optional inclusion of cleaning chemistry.

As in particular the representation after 5 lets recognize, puts the housing 16 the dosing unit 16 two opposite sides of the housing ready, each with an opening 18 respectively 19 are equipped. The opening 19 is designed to be closed, for which purpose designed as a pivotable flap locking member 23 is used.

Inside the case 16 is one with the locking member 23 co-operating thermoactor 20 arranged. This triggers from a certain rinsing bath temperature of, for example, 60 ° C, as a result, a plunger extends and the pivotally mounted flap in their in 5 shown open position pivoted.

The dosing unit 15 is replaceable on the user side within the detergent dispenser 14 arranged. To be able to take this user side, are the side of the detergent receptacle 14 handholds 21 provided by a user with his fingers for grasping the dosing unit 15 can dive.

The function of the embodiment according to the invention is as follows:

The dosing unit 15 can either by the user either so in the detergent 14 be used that the Spülflottenkanal 13 is blocked, like this 4 indicates, or so, that an inflow of wash liquor through the spigot of the spray arm 5 in the rinsing liquor channel 13 basically possible, like this 3 shows. To these different orientations of the dosing unit 15 for a user to visualize is the top of the dosing unit 15 an arrow 22 is formed, based on the orientation of the blocking position after 4 or the passage position after 3 can be recognized.

If the dosing unit 15 in the in 4 is shown a blocking of the Spülflottenkanals 13 , Consequently, a charge of Sprüharmflügels 8 rinsing excluded basically. 3 shows, however, the Nichtblockierstellung the Spülflottenkanals 13 through the dosing unit 15 depending on the program, a loading of Spülflottenkanals 13 with rinsing liquor can take place, which by the direction of the Sprüharmflügels 8th pointing arrow 22 is symbolized.

If the dosing unit 15 in the non-blocking position according to 3 may be a loading of Spülflottenkanals 13 basically take place with rinse liquor. This is possible if the as blocking element 23 Serving flap in its open position according to 5 located. In this position, the locking member 23 through the case 16 the dosing unit 15 arranged actuator 20 held. The open position of the locking member 23 results therefore in consequence of an activation of the actuator 20 ,

The actor 20 is preferably a temperature-dependent triggering thermoactor. This triggers only at a certain temperature of, for example, 60 ° C. A triggering of the actuator thus takes place only from a certain rinsing pool temperature. As long as this temperature is not reached, the as blocking element 23 serving flap automatically held in the closed position due to the Spülflottendrucks, that is, the opening 19 of the housing 16 is closed, whereby an inflow of wash liquor is prevented. As soon as a rinsing program section is carried out, according to which the rinsing liquor is heated to a predeterminable temperature of, for example, 60 ° C., activation of the actuator occurs 20 which is opposite to the locking member 23 acting Spülflottendrucks a pivoting movement of the locking member 23 effected in the open position. Once this is achieved, the opening is 19 unlocked, so that rinse the housing 16 happen and through the Spülflottenkanal 13 into the spray arm wing 8th can flow in.

Inside of the housing 16 provided volume space 17 optional cleaning agent is housed in the case of an open locking member 23 is flushed out by the inflowing rinse liquor.

According to a particular proposal of the invention is a locking device 24 provided for a position fixation of the spray arm 5 in a predefined position. This locking device 24 is in the 6 and 7 shown, where 6 the unlocked position and the 7 the locked position of the spray arm 5 shows.

As can be seen from a synopsis of 6 and 7 results, has the locking device 26 via a locking means 25 in the embodiment of a pen. This works with one on the spray arm 5 trained stop 26 together. Once there is an activation of the locking device 24 comes, the locking device moves 25 in the writable by the spray arm trajectory, as a result, the spray arm 5 with his stop 26 on the locking means 25 auffährt and so fixed in its position, that is, is arrested, as can be seen from the presentation 7 lets recognize.

By the locking device 25 becomes the spray arm 5 blocked in his otherwise carried out twisting movement. The result is in particular the Sprüharmflügel 8th intense for a predetermined period of time on a specific area of the washing compartment 3 one. In this area can then take place an additional intensive cleaning.
