Definitions
- Household dishwasher with at least one air drying device with at least one air drying device
- the present invention relates to a household dishwasher with a washing container for accommodating dishes, glasses, cutlery or similar items to be washed, and with at least one loading unit for accommodating items to be washed.
- a household dishwasher runs through one or more liquid-carrying partial wash cycles, for example a pre-wash cycle, a cleaning cycle, an intermediate wash cycle and a final rinse cycle. This is usually followed by a drying cycle.
- washing liquid ie so-called washing liquor
- Such liquid distribution devices can be formed, for example, by rotating spray arms, by a roof shower and / or by a movable spray nozzle, such as a roof top, in the washing compartment.
- washing liquid can be introduced into the washing container, preferably in such a way that it acts directly or indirectly on the wash ware held there in loading units, for example pull-out crockery baskets and / or cutlery drawers.
- Water can preferably be used as the washing liquid for the respective liquid-carrying partial wash cycle, to which detergent and / or rinse aid can optionally be added.
- Fresh water from a domestic water pipe, which is softened in particular by means of a softening system of the dishwasher, or service water that is stored in a storage tank of the dishwasher from the final rinse cycle of the preceding dishwasher program can preferably be used for the pre-wash cycle.
- fresh water that has been softened by means of the water softening system and mixed with cleaning agent is preferably used for the cleaning process.
- Softened fresh water is preferably used in the intermediate rinse.
- fresh water that has been softened by means of the water softener and mixed with rinse aid is preferably used.
- Various drying methods are known in order to dry the items to be washed as well as possible at the end of the respective dishwashing program. These are in particular so-called self-heat drying, condensation drying (in particular by means of a heat exchanger on a side wall of the washing compartment to cool it down), drying through a door opening at the end of the drying cycle, sorption drying such as with zeolite, etc. ... These processes in particular cause liquid droplets that stick to the items to be washed after the last liquid-carrying partial wash cycle of a running dishwashing program are dried away.
- washing liquid collects in an upwardly protruding recess, e.g. B. sink, groove or other cavity of a wash ware part, and if it remains there on the top, this remaining amount of liquid is often too large to be dried away by a conventional drying system.
- a typical example of such a recess is a vaulted bottom of an overhead cup or a corresponding glass.
- the remaining liquid can usually only be removed by the user by manually tilting the respective wash ware and / or by drying it with a tea towel which is inconvenient and time consuming.
- the invention is based on the problem of providing a household dishwasher with a drying option, with the aid of which a drying cycle to be carried out during the washing cycle-final drying cycle
- Dishwashing program largely remove quantities of liquid in, in particular, depressions on the upper side, such as, for example, depressions, depressions, hollows or other cavities from parts of the items to be washed held in loading units.
- the invention solves the problem by means of an object with the features of claim 1. With regard to advantageous configurations and developments of the invention, reference is made to claims 2 to 15.
- this can be inclined - preferably by a few degrees - when the speed is increased (in particular with respect to a vertical axis) or be inclined from the outside.
- the air flow downwards for drying varies in its direction.
- the frame can be raised in this corner area by, for example, switching on a first fan wheel provided in a corner area of the frame and thereby inclined overall, in particular with respect to a vertical axis. This changes the air flow direction of all fan wheels held on the frame at the same time.
- the fan wheels of this frame are driven through at changing speed and / or one after the other, the frame is aligned so that it varies over time, so that the resulting air flow (or air flows) changes direction again and again and thereby the drying behavior for the wash ware acted upon by the resulting air flow (or the resulting air flows) is optimized.
- each fan wheel can vary individually in its air flow.
- speed variations on each fan wheel in order to achieve an - in particular slight - angling of the respective fan wheel by varying the air flow strength and thus to change the direction of the air flow emitted or blown out by the respective fan wheel.
- the air flows from the multiple fans do not have to run parallel to one another.
- the change in the direction of the output air flows can advantageously be made possible by providing an elastically deformable suspension of the frame and / or the fan wheel (s) for positional mobility, in particular at least with respect to a vertical axis.
- elastically deformable suspensions via support elements containing rubber, silicone and / or TPE / TPV can be provided.
- straps or sealing cuffs are possible in the suspensions.
- an elastically deformable suspension is achieved by means of springs.
- each fan wheel is held by several or by means of several suspensions which are differently elastic. Even then, the upward force caused by the air flow changes the angular position of the fan wheel and the output air flow.
- the exit angle can be varied using one or more pivot levers in the respective suspension.
- a fan wheel can preferably be held by means of an approximately horizontally located pivot lever which is pivoted about a horizontal axis with one degree of freedom is movable and therefore makes the fan wheel a little bit positionally movable around the pivot axis on a circular path.
- a change in the blow-out direction can preferably be brought about, in particular, solely by operating the respective fan wheel, which, by virtue of its downward thrust, preferably adjusts the fan wheel relative to the vertical.
- an external force to be introduced to vary the angle, for example by means of an electric motor. This can act, for example, via cams on several pivot levers that hold the fan wheels.
- one or more fan wheels can be held in its or their rest position in a horizontal loading plane of a loading unit (for example a crockery basket or a cutlery drawer) or the upper wall.
- a loading unit for example a crockery basket or a cutlery drawer
- the one or more fan wheels can preferably be rotated about a vertical axis or axes.
- the respective fan wheel in addition to its rotational movement, is positionally movable, in particular pivotable, about an axis of rotation predefined for it.
- the drive motor assigned to the respective fan wheel can preferably be arranged above the respective fan wheel, so that a compact structural unit with only a very small structural height is formed from the drive motor and fan wheel. If one or more fan wheels suck in and blow out air from the closed washing container, no outlets in the washing container wall and also no valves or other additional structural units are required, so that the structure remains simple. Alternatively, it is also possible for air to be sucked in from the outside, for example also by automatically opening the door a little.
- Fig. 1 is a schematic perspective view obliquely from the front of an embodiment form of a household dishwasher with a front door here and a washing container inside,
- FIG. 2 shows an exemplary detailed view of a washing container loaded with items to be washed and fan wheels attached below its upper wall, in a side view, with a rigid connection of the fan wheels that cannot be tilted relative to a vertical axis being provided according to this figure
- FIG. 3 shows the washing container according to FIG. 2 in a view from the front
- FIG. 4 shows a schematic perspective view of a household dishwasher with a frame that is movably held at the top via four elements, on which fan wheels - not shown here - can be held or held,
- FIG. 5 shows a partially sectioned detail view of a fan wheel suspended via a flexible, sealing sleeve
- FIG. 6 shows a view similar to FIG. 5, but with two fan wheels side by side
- FIG. 7 shows a plan view of a frame as in FIG. 4, but here four fan wheels are held on the frame and can be moved individually with respect to the frame by means of differently elastic mountings
- 8 shows a view similar to FIG. 7, but with the fan wheels being held individually movable on the frame via pivot levers,
- FIG. 1 shows a schematic representation of a household dishwasher 1.
- a partially outwardly open or closed device body 5 which is also often referred to as the body, at least one washing container 2 for receiving items to be processed such as dishes, pots, cutlery, Glasses, cooking utensils, etc.
- the items to be washed can be held, for example, in loading units 10, 11, namely in crockery baskets 11 and / or a flat cutlery drawer 10 according to the drawing, and can be acted upon by so-called washing liquor or washing liquid.
- two crockery baskets 11 are arranged one above the other and an additional cutlery drawer 10 is arranged as loading units in the upper region of the washing compartment 2. This arrangement is not mandatory.
- the customer can also, for example, remove an upper crockery basket 11 or the cutlery drawer 10 for a specific wash cycle. In the examples of the other figures, however, no cutlery drawer 10 is provided.
- Washing liquor is understood to mean fresh water or, in particular, water that circulates during operation, preferably softened water, with or without cleaning agent and / or rinsing agent and / or drying agent.
- the washing container 2 can have an at least substantially rectangular - in particular approximately square - plan with a front side V facing a user in the operating position.
- This front V can form part of a kitchen front from kitchen furniture standing next to one another or, in the case of a stand-alone device, it can also be without reference to other furniture.
- the washing compartment 2 can be closed by a door or flap 3, in particular on this front side V.
- This door 3 is shown in Figure 1 in a partially open and then inclined to the vertical position. In its closed position, however, it stands upright and, according to the drawing, is after its opening around a lower horizontal axis can be pivoted open at the front and bottom in the direction of arrow 4, so that it is at least almost horizontal in the fully open position.
- the door 3 can be provided with a decorative plate 6 in order to experience a visual and / or haptic upgrade and / or an adaptation to surrounding kitchen furniture.
- the household dishwasher 1 is designed here as a stand-alone device or as a so-called partially integrated or also as a fully integrated device.
- the device body 5 can also essentially terminate with the outer walls of the washing compartment 2.
- a housing surrounding this outside can then be partially or entirely dispensable.
- a base 12 for receiving, in particular, functional elements, such as a circulating pump and / or waste water pump for the washing liquor.
- the movable door 3 is assigned in its upper area a control panel 8 extending in the transverse direction Q of the dishwasher, which can include an engagement opening 7 accessible from the front V for manual opening and / or closing of the door 3.
- the dishwasher In the transverse direction Q, the dishwasher often has an extension of 45, 50 or 60 centimeters. In the depth direction from the front V to the rear, the extension is often also about 60 centimeters. The values are not mandatory.
- the washing container 2 is bordered all around by a total of three fixed vertical walls 13 and two horizontal walls 15 when the door or flap 3 is closed, one of which forms a ceiling as the upper wall and another a floor as the lower boundary of the washing container 2.
- the wall 15 that forms the bottom of the washing compartment 2 and delimits it essentially downwards, like the upper wall 15, is approximately horizontal, that is to say parallel to an outer base B on which the dishwasher 1 stands.
- At least one of the loading units 10, 11 is or are assigned one or more fan wheels L1, L2, L3, L4 rotatable in the washing container 2, with which air can be sucked in and blown out on the one hand, in particular with a flow component pointing into the washing container 2.
- fan wheels L1, L2, L3, L4 can be seen in FIG. 7 or FIG. However, the number is not mandatory.
- These are arranged here in the upper region 16 of the washing compartment 2 and each comprise a propeller-like part 17 and a drive part 18.
- the motors 18 are here each arranged axially close above the fan wheels L1, L2, L3, L4 and are controlled by a control device outside the washing compartment 2 controllable, so also electrically connected to this.
- the drives 18 are in particular arranged axially directly above the respective fan wheel L1, L2, L3, L4 and are preferably designed as a flat package, in particular as a contactless synchronous motor. This advantageously results in a very low structural height with an axial extension of less than four centimeters.
- the total structural height of the motor 18 and fan wheel 17 is therefore advantageously less than five centimeters, so that it can also be assigned to a flat cutlery drawer 10 or a similar loading unit.
- the fan wheels L1, L2, L3 and L4 can be active in the drying phase and serve to improve the drying result of the items to be washed 19, which is shown in FIGS. 2 and 3, for example.
- They As they rotate around a vertical axis 23, they convey air and blow it onto the wash ware 19 with a component pointing downwards exactly about this vertical axis 23 instead, but about an axis that is slightly angled to this and can also vary its position, as will be explained in more detail below.
- This positional mobility is indicated at the bottom in FIG. 5 by the pivoting arrow about the vertical axis 23 shown there. ok
- the drying result is significantly improved in the case of cup or glass shelves 20 or similar fillets, indentations or the like pointing upwards.
- the one or more fan wheels L1, L2, L3, L4 is or are assigned to at least one loading unit 10, 11 and / or the upper wall 15 delimiting the washing container 2 or a separate frame 21 and held thereon.
- a cutlery drawer it is also possible, for example, for a cutlery drawer to be divided lengthways or crossways, so that the relevant symmetry is canceled. Only, for example, the part on the right from the user forms a cutlery drawer 10 and can be pulled out towards the front, towards the front V, in order to facilitate the usual loading and unloading. In the left part from the front, however, there can be two fan wheels L1 and L3 of the same size (not shown). Here, the fan wheels L1, L3 can also lie in the same horizontal plane as the cutlery drawer 10 and then do not have to protrude downwards. As a result, the full loading height is retained in the loading unit (s) 11 below, which is very favorable in particular for tall items, such as glasses with a long stem.
- one or more fan wheels L1, L2, L3, L4 are suspended from a frame 21 that holds them together. This is itself suspended on a loading unit 10, 11 or - as indicated here - on the wall 15 delimiting the washing container 2 at the top so as to be movable relative to a vertical axis 23.
- a loading unit 10 11 or - as indicated here - on the wall 15 delimiting the washing container 2 at the top so as to be movable relative to a vertical axis 23.
- four suspensions 22 are used in the outer corner areas.
- These suspensions 22 can be elastically deformable, the Elasticity is achieved via rubber, silicone and / or TPE / TPV containing support elements.
- the mobility of the suspensions 22 can be achieved by means of springs.
- an elastic / flexible suspension 22 of the complete frame 21 is formed on the washing container 2.
- the fan or fans L1, L2, L3, L4 - not shown in FIG. 4 - can, on the other hand, be suspended in a fixed manner or even elastically in the frame 21.
- the force that acts on the fan wheel as a result of the operation of the fan wheel, for example L1, which releases air downward, can be completely passed on to the frame 21. If, for example, a fan is rigidly arranged in the front left corner 24 of the frame 21 and blows out downwards, this fan is pushed upwards.
- This thrust is transmitted through the rigid suspension to the frame 21, which then, due to its movable suspensions 22, lifts at this corner 24 and thus positions the fan at a slight angle to the vertical. It is possible to run through the speed of the mentioned fan in several phases, so that the resulting thrust varies. Only when the thrust is in the order of magnitude of the weight of the fan does the mentioned fan lift. If several fans are held in the frame 21, which is particularly favorable, the fans can be activated one after the other, so that different corners of the frame 21 are lifted alternately. As a result, in conjunction with the soft mounting 22, the frame 21 is pressed upwards in the area of the respective driven motor and thereby receives the desired change in direction. The change in direction with respect to the vertical is only a few angular degrees up to approx. 5 °, since otherwise the frame 21 with the respective upwardly moving corner (for example 24) could strike at the top.
- the elastic suspension 22 also results in a decoupling from the walls 13, 14, 15 of the washing compartment 2, so that the noise and vibration behavior are also significantly improved.
- the frame 21 can protrude downward like an apron and thus also form a certain protection for the fan wheels L1, L2, L3, L4 as well as protection against interference with them. Additionally or alternatively, it is also possible that the or each fan wheel L1, L2, L3, L4 is suspended individually on the holding frame 21 or on the wall 15 delimiting the washing container 2 at the top so as to be movable at least with respect to a vertical axis 23. For example, an elastic suspension of each fan wheel L1, L2, L3, L4 on the frame 21, which is then firmly connected to the dishwasher 1, is possible.
- a movable suspension of one or each individual fan wheel L1, L2, L3, L4 is shown in Figure 5 and Figure 6 for attachment to the upper wall or ceiling wall 15 of the washing container:
- the attachment of a single fan wheel L1 is shown
- FIG. 6 shows the attachment of two fan impellers L1 and L2 which, viewed from the front V, lie next to one another.
- the suspension 22 is hooked into a bore 25 in the upper wall 15 in a form-fitting manner. This bore 25 penetrating the outer wall 15 also makes it necessary for the suspension 22 to be circumferentially sealing.
- a movable suspension of one or each individual fan wheel L1, L2, L3, L4 is shown in Figure 7 for an elastic attachment to the frame 21:
- four fan wheels L1, L2, L3, L4 are provided as an example, which the respective corner areas of the in plan view at least almost square frame 21 are assigned.
- the suspension 22 of each fan wheel (for example L1) with respect to the frame 21 is implemented here in each case by means of three bands, carriers or similar mountings 22a, 22b, 22c.
- These holders 22a, 22b, 22c act in the manner of approximately horizontally lying connecting webs. They can have different elasticities from one another, so that the thrust occurring during operation of a respective fan wheel L1, L2, L3, L4 automatically adjusts its defined inclination to the vertical axis 23.
- the bracket 22a can be significantly more elastic than the brackets 22b and 22c, as a result of which the fan wheel L1 is lifted more transversely on the outside and the air flow exiting downwards is directed a little further transversely outside into the corner area 24.
- the brackets 22a, 22b, 22c which protrude radially from the motor 18 as connecting webs, are again realized, for example, from rubber, TPE ... and / or as a spring.
- a limited wobbling movement of each fan wheel L1, L2, L3, L4 about the vertical axis 23 is also possible during operation.
- the fan wheel (s) L1, L2, L3, L4 is or are fastened in the respective suspension 22 via, for example, a pivot lever 27 with a movable joint / spherical bearing 28.
- the pivot levers 27 run, for example, in the plan view according to FIG. 8 diagonally to a central joint 28 in the frame 21, so that a wobbling movement about the vertical axes 23 can occur during operation.
- the central arrangement of the joint 28 is not mandatory. It is also possible that a separate joint 28 is provided for each of the fan wheels L1, L2, L3, L4.
- the longitudinal distance between the pivot lever 27 and the joint 28 can vary, so that the movement pattern can also be varied.
- each fan wheel L1, L2, L3, L4 in turn is allowed to run for a few seconds with a vertical discharge direction and then for a few seconds at full speed in order to enable a brief inclined discharge by the fact that the respectively controlled fan wheel L1, L2, L3, L4 has a Thrust generated, which leads to a movement of this fan wheel in its suspension or the multiple fan wheels L1, L2, L3, L4 around a common suspension.
- the control of the several fan wheels L1, L2, L3, L4 one after the other then leads to a large number of blow-out directions and to particularly good drying and particularly good drying, especially in the corner areas.
- one or more fan wheels L1, L2, L3, L4 can be or can be changed from the outside by a motor in their position relative to a vertical axis 23, for example also jointly via a camshaft.
- one to four fan wheels L1, L2, L3, L4 are provided per suspension 22.
- one or more fan wheels L1, L2, L3, L4 are held in their rest position in a horizontal loading plane of the loading unit 10, 11 or the wall 15. As a result of the positional mobility, a permanent or, in particular, increasing and decreasing angling to this plane by a few angular degrees can then occur during operation.
- the fan wheel (s) L1, L2, L3, L4 can be arranged axially symmetrically to a vertical longitudinal center plane and / or axially symmetrically to a vertical transverse center plane of the domestic dishwasher 1.
- a single fan wheel L1 arranged centrally in the transverse and depth directions, can be provided, which with its diameter can almost fully utilize the available area in the washing compartment 2, i.e. it can have a diameter of up to 48 centimeters.
- the fan wheels L1, L2, L3, L4 are arranged axially symmetrically to a vertical longitudinal center plane and possibly also axially symmetrically to a vertical transverse center plane of the dishwasher 1.
- a symmetry to the vertical transverse center plane i.e. a user standing in front of the dishwasher 1 will find the same conditions to the left and right.
- an external air supply line or air discharge line is not mandatory, but the one or more fan wheels L1, L2, L3, L4 can suck in air from the closed washing container 2 and blow it out. Automated opening of the door 3 by a gap is also possible in the drying phase.
- the hydraulic effective area for drying the cup base and the like is advantageously significantly increased by the positionally movable, in particular pivotable, suspension of one or more fan wheels.
- the invention achieves the following advantages in particular:
- One or more fan wheels L1, L2, L3, L4 can optionally be assigned to a cutlery drawer 10 and / or a crockery basket 11 and / or the mentioned separate frame 21 and / or the upper wall 15, depending on the design and spatial conditions .
