Definitions

  • the present invention relates to a household dishwasher with a washing container for holding dishes, glasses, cutlery or similar items to be washed, and with at least one loading unit for holding items to be washed according to the preamble of claim 1.
  • a domestic dishwasher goes 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 i.e. 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 gyroscope, in the washing container.
  • washing liquid can preferably be introduced into the washing container in such a way that the items to be washed held there in loading units, for example pull-out dish baskets and/or cutlery drawers, are directly or indirectly exposed to it.
  • Water can preferably be used as the washing liquid for the respective liquid-carrying partial wash cycle, which can optionally be mixed with cleaning and/or rinse aid.
  • fresh water from a domestic water pipe which is softened in particular by means of a water softener in the dishwasher, or service water, which is stored in a storage tank in the dishwasher from the final rinse cycle of the previous dishwashing program, can be used for the pre-wash cycle.
  • Fresh water that has been softened by means of the water softener and mixed with cleaning agent is preferably used for the cleaning cycle.
  • Softened fresh water is preferably used in the intermediate wash cycle.
  • Fresh water that has been softened by means of the water softener and mixed with rinse aid is preferably used for the final rinse cycle.
  • a depression, groove or other cavity of a dishwashing item the amount of liquid that has remained is often too large to be dried away by a conventional drying system.
  • a typical example of such a depression is a curved bottom of a cup or glass that is standing upside down. This residual liquid can usually only be removed after the end of the drying cycle by the user tipping the respective item of washware away by hand and/or drying it with a tea towel, which is uncomfortable and time-consuming.
  • the GB 1 530 734 A concerns only a drying hood which is arranged downstream of the outlet of a commercial dishwasher.
  • the drying hood is arranged so as to be movable in a vertical direction above a table on which a crockery basket with wet crockery is placed after it has been removed from the dishwasher's washing compartment.
  • a fan wheel which can be driven by an electric motor is fixed in place on the inside of its ceiling wall, beneath which electric heating resistors are arranged.
  • the hood as a whole can be lowered down over the crockery basket into a Lower the drying position, in which an apron on its lower part covers the circumference of the
  • the fan motor and the electric heating elements are then switched on.
  • the rotating fan sucks outside air into the interior of the hood through an opening in the ceiling wall and blows it vertically downwards. The same stationary air flow is always generated.
  • the JP 2005 058552 A concerns a so-called drawer dishwasher. This has a drawer-shaped washing box in its outer casing.
  • Dish baskets are housed in this above spray nozzles that rotate during rinsing.
  • the drawer-shaped wash box can be moved out of the front of the housing for loading and/or unloading dishes.
  • An electric motor-driven fan wheel is attached or fixed in place on the outside of the rear of the drawer-shaped wash box. This pumps outside air into the drawer-shaped wash box during the drying phase of the dishwashing program.
  • WO 2019/015967 A1 a household dishwasher with a washing container and associated fan wheels.
  • the invention is based on the problem of providing a household dishwasher with a drying facility with the aid of which, during the final drying cycle of a dishwashing program, liquid quantities can be collected in particularly upper-side recesses, such as troughs, depressions, grooves or other cavities in parts of the wash items held in loading units, can be largely removed.
  • a washing container in a household dishwasher at least one loading unit and/or an upper wall delimiting the washing container is provided with a or several fan wheels rotatable in the washing container are assigned, with which air can be sucked in on the one hand and blown out on the other hand, wherein one or more of the fan wheels are suspended so as to be movable in position, in particular pivotable, at least with respect to a vertical axis during the drying cycle of the dishwashing program to be carried out, air can be blown out onto the dishes located underneath, wherein the angle of the air blowing out can vary.
  • the movable suspension of a fan wheel allows it to be tilted - preferably by a few degrees - when the speed increases (in relation to a vertical axis) or to be tilted from the outside. This changes the direction of the air flow directed downwards for drying.
  • 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 be tilted overall relative to a vertical axis. This changes the air flow direction of all fan wheels held on the frame simultaneously.
  • the fan wheels of this frame are moved at varying speeds and/or one after the other, the frame is aligned in a varying manner over time, so that the resulting air flow (or air flows) repeatedly changes direction and the drying behavior for the dishes exposed to the resulting air flow (or air flows) is thereby optimized. This ensures an improved drying result for the drying cycle of a wash cycle of a dishwashing program to be carried out.
  • each fan wheel is individually attached to a holding frame or a wall delimiting the top of the rinsing container at least relative to a vertical axis is suspended in a positionally movable manner, each fan wheel can individually vary its air flow.
  • speed variations on each fan wheel in order to achieve a - particularly slight - angle of the respective fan wheel by varying the air flow strength and thus change the direction of the air flow emitted or blown out by the respective fan wheel.
  • the air flows of the several fans do not have to run parallel to one another.
  • the change in the direction of the emitted air streams can advantageously be made possible by providing an elastically deformable suspension of a frame on which the one or more fan wheels are mounted and/or of the fan wheel(s) for positional mobility at least relative to a vertical axis.
  • elastically deformable suspensions can be provided via support elements containing rubber, silicone and/or TPE/TPV.
  • bands or sealing sleeves are possible in the suspensions.
  • each fan wheel it is also possible for each fan wheel to be held by several suspensions, which have different degrees of elasticity. In this case, too, the angular position of the fan wheel and the air flow output changes, for example, due to the upward force caused by the air flow.
  • a variation of the outlet angle can be achieved via one or more pivot levers in the respective suspension.
  • a fan wheel can preferably be held via an approximately horizontal pivot lever that can move around a horizontal axis with one degree of freedom and therefore allows the fan wheel to move a small distance around the pivot axis on a circular path.
  • a change in the blow-out direction can be effected in particular solely by the operation of the respective fan wheel, which, through its downward thrust, preferably sets the fan wheel relative to the vertical.
  • an external force input for angle variation can also be possible. This can be done via an electric motor, for example. This can act via cams on several pivoting 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 are preferably rotatable about a vertical axis or vertical axes.
  • the respective fan wheel is movable in position, in particular pivotable, in addition to its rotational movement about a predetermined axis of rotation. This makes it possible for its axis of rotation to assume different positions during the drying phase of a dishwashing program to be carried out and thus for it to blow air streams in different spatial directions in the washing container of the household dishwasher.
  • the drive motor assigned to the respective fan wheel can preferably be arranged above the respective fan wheel, so that the drive motor and fan wheel each form a compact unit with only a very small installation height.
  • FIG. 1 shows a schematic representation of a household dishwasher 1.
  • a device body 5 that is partially open or closed to the outside, which is also often referred to as a corpus, this has at least one washing container 2 for holding items to be washed, such as dishes, pots, cutlery, glasses, cooking utensils, etc.
  • the items to be washed can be held in loading units 10, 11, namely according to the drawing in dish baskets 11 and/or a flat cutlery drawer 10, and can be exposed to so-called washing liquor or washing liquid.
  • two dish baskets 11 are arranged one above the other and an additional cutlery drawer 10 is arranged in the upper area of the washing container 2 as loading units. This arrangement is not mandatory.
  • the customer can also remove an upper dish basket 11 or the cutlery drawer 10 for a specific wash cycle, for example. In the examples in the other figures, however, no cutlery drawer 10 is provided.
  • washing liquor is understood to mean fresh water or, in particular, water that is circulated during operation, preferably softened water, with or without cleaning agent and/or rinse aid and/or drying agent.
  • the washing container 2 can have an at least essentially rectangular - in particular approximately square - floor plan with a front V facing a user in the operating position.
  • This front V can form part of a kitchen front made up of kitchen units standing next to one another or, in the case of a stand-alone appliance, can also be without reference to other units.
  • the washing container 2 can be closed in particular at this front side V by a door or flap 3.
  • This door 3 is in Figure 1 shown in a partially open position and then at an angle to the vertical. In its closed position, however, it stands upright and, according to the drawing, can be swung forwards and downwards in the direction of arrow 4 about a lower horizontal axis to open it, so that in the fully open position it is at least almost horizontal.
  • the door 3 On its outer and front side V, which is vertical in the closed position and faces the user, the door 3 can be provided with a decorative panel 6 in order to provide an optical and/or haptic enhancement and/or adaptation to surrounding kitchen furniture.
  • the domestic dishwasher 1 is designed here as a stand-alone or as a so-called partially integrated or fully integrated device.
  • the device body 5 can also essentially be flush with the outer walls of the washing container 2.
  • a housing surrounding this on the outside can then be partially or completely dispensable.
  • a base 12 for accommodating functional elements in particular, such as a circulation pump and/or waste water pump for the washing liquid.
  • the movable door 3 is assigned a control panel 8 in its upper area, which extends in the transverse direction Q of the dishwasher and can include an access opening 7 accessible from the front V for manually opening and/or closing 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 around 60 centimeters. The values are not mandatory.
  • the washing container 2 When the door or flap 3 is closed, the washing container 2 is delimited all around by a total of three fixed vertical walls 13 and two horizontal walls 15, one of which forms a ceiling as the upper wall and another a floor as the lower boundary of the washing container 2.
  • At least one of the loading units 10, 11 is or are assigned one or more fan wheels L1, L2, L3, L4 that can rotate in the rinsing tank 2, with which air is can be sucked in and blown out on the other hand, in particular with a flow component pointing into the rinsing container 2.
  • Figure 7 or Figure 8 four fan wheels L1, L2, L3, L4 can be seen. However, the number is not mandatory. These are arranged here in the upper area 16 of the washing container 2 and each comprise a propeller-like part 17 and a drive part 18.
  • the motors 18 are each arranged axially close above the fan wheels L1, L2, L3, L4 and can be controlled by a control device outside the washing container 2, and are therefore also electrically connected to it.
  • the drives 18 are arranged in particular 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 installation height with an axial extension of less than four centimeters.
  • the total installation height of the motor 18 and fan wheel 17 is therefore advantageously less than five centimeters, so that it is also possible to assign them 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 wash items 19, which are, for example, in the Figures 2 and 3 is shown.
  • the drying result is significantly improved with cup or glass bottoms 20 pointing upwards or with similar concave grooves, indentations or the like.
  • the one or more fan wheels L1, L2, L3, L4 is or are assigned to and held on at least one loading unit 10, 11 and/or the upper wall 15 delimiting the rinsing container 2 or a separate frame 21.
  • a cutlery drawer it is also possible, for example, for a cutlery drawer to be divided lengthways or crossways, so that the symmetry in this regard is eliminated. Only the part to the right of the user forms a cutlery drawer 10 and can be pulled out towards the front V to facilitate loading and unloading as usual. In the part to the left of the front, however, there can then 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 do not have to protrude downwards. This means that the full loading height is maintained in the loading unit(s) 11 below, which is particularly advantageous for tall items such as glasses with long stems.
  • one or more fan wheels L1, L2, L3, L4 are suspended from a frame 21 that holds them together.
  • This frame is itself suspended from a loading unit 10, 11 or - as indicated here - from the wall 15 that delimits the top of the rinsing container 2 in a movable manner relative to a vertical axis 23.
  • four suspensions 22 in the outer corner areas are used for this purpose.
  • These suspensions 22 can be elastically deformable, with the elasticity being achieved via support elements containing rubber, silicone and/or TPE/TPV.
  • the mobility of the suspensions 22 can be achieved via springs.
  • This thrust is transferred to the frame 21 by the rigid suspension, which then lifts this corner 24 due to its movable suspensions 22, thereby positioning the fan slightly at an angle to the vertical. It is possible to run the speed of the fan in several phases so that the resulting thrust varies. The fan is only lifted when the thrust is on the order of magnitude of the weight of the fan. If several fans are held in the frame 21, which is particularly advantageous, the fans can be controlled one after the other so that different corners of the frame 21 are lifted alternately. In conjunction with the soft bearing 22, the frame 21 is pushed upwards in the area of the motor being driven in each case and thus receives the desired change in direction. The change in direction from the vertical is only a few degrees up to about 5°, since otherwise the frame 21 could hit the top with the corner that is moved upwards (for example 24).
  • the elastic suspension 22 also results in a decoupling from the walls 13, 14, 15 of the rinsing container 2, so that the noise and vibration behavior are also significantly improved.
  • the frame 21 can protrude downwards like an apron and thus also provide a certain protection for the fan wheels L1, L2, L3, L4 as well as protection against interference with them.
  • each fan wheel L1, L2, L3, L4 it is also possible for the or each fan wheel L1, L2, L3, L4 to be suspended individually on the holding frame 21 or the wall 15 delimiting the washing container 2 at the top, at least relative to a vertical axis 23.
  • an elastic suspension of each fan wheel L1, L2, L3, L4 on the frame 21 is possible, which is then firmly connected to the dishwasher 1.
  • a movable suspension of one or each individual fan wheel L1, L2, L3, L4 is in Figure 5 and Figure 6 for mounting on the upper wall or ceiling wall 15 of the washing tank:
  • Figure 5 The installation of a single fan wheel L1 is shown, in Figure 6 the attachment of two fan wheels L1 and L2, which lie next to each other as seen from the front V.
  • a sleeve running around the vertical axis 23 and sealing here is provided as an elastically deformable suspension 22, which in turn contains rubber, silicone and/or TPE/TPV.
  • the suspension 22 is here positively hooked into a hole 25 in the upper wall 15. This hole 25 penetrating the outer wall 15 also makes it necessary for the suspension 22 to be sealing all the way around.
  • a movable suspension of one or each individual fan wheel L1, L2, L3, L4 is in Figure 7 for an elastic attachment to the frame 21:
  • Four fan wheels L1, L2, L3, L4 are provided here as an example, which are assigned to the respective corner areas of the frame 21, which is at least almost square in plan view.
  • the suspension 22 of each fan wheel (for example L1) relative to the frame 21 is realized here via three bands, supports or similar holders 22a, 22b, 22c. These holders 22a, 22b, 22c act like approximately horizontal connecting webs. They can have different elasticities to one another, so that the thrust of a respective fan wheel L1, L2, L3, L4 occurring during operation automatically sets its defined inclination to the vertical axis 23.
  • the bracket 22a can be significantly more elastic than the brackets 22b and 22c, whereby the fan wheel L1 is raised more transversely on the outside and the air flow escaping downwards is directed a little transversely outwards into the corner area 24.
