DETAILED DESCRIPTION
[0115] FIG. 1 shows a schematic representation of a pre-drying device 1 according to embodiments of the invention. This pre-drying device 1 is provided with at least one blower nozzle 2.
[0116] FIG. 2 shows a schematic representation of a dishwasher 100 according to embodiments of the invention, in which this dishwasher 100 is equipped with a cleaning device 112, a drying device 113, an air pressure generating device 120 and a pre-drying device 1 according to embodiments of the invention. Between the air pressure generating device 120 and the pre-drying device 1 a compressed air tank 121 is provided with at least one valve 118. Via this valve 118, which in the air duct direction is upstream of a blower nozzle 2, the dishes 3 can be treated with a jet of air or in pulses with pulsed jets of air controlled by a controller 119. If the compressed air tank 121 has a number of compressed air outputs, in particular each with a valve 118, it can also function simultaneously as distributor for the air duct system 6.
[0117] FIG. 3 shows a sectional representation of a dishwasher 100 according to embodiments of the invention with a pre-drying device 1. The dishwasher 100 includes a housing 111, which determines an interior 110 of the dishwasher 100. The pre-drying device 1 shown is above the dishes 3 and has two blower nozzles 2. The dishes 3 have a depression 5, which is filled with a rinsing liquid 10. As shown, the opening 4 of the depression 5 of the dishes 3 is aligned by a placement area 116 such that the opening 4 of the depression 5 is almost opposite the blowing direction R of the single blower nozzle 2. In addition to the placement area 116, a mounting 117 can also be provided on the dish rack 114. The placement area 116 and the mounting 117 represent dish housing devices 115 for the dish rack 114.
[0118] FIG. 4 shows an advantageous design of the air duct system 6. In this design, the air duct system 6 is designed as a plate 7. On this plate 7, a multitude of blower nozzles 2 is provided, which are configured either rigidly and/or adjustably. The blower nozzles 2 can, in this design, be controlled individually following one another and/or in pairs and/or in groups.
[0119] FIG. 5 shows a further advantageous design of the air duct system 6, which in this embodiment is formed as a rail system 11 with a spindle 24 to drive blower nozzle blocks 21 and/or blower nozzles 2. The rail system 11 also includes coupling gears 9 for the drive and at least one rail 11 on which blower nozzle blocks 21 and/or blower nozzles 2 are arranged so as to be movable.
[0120] FIG. 6 shows a further advantageous design of the air duct system 6. In addition, four identical disks 13 are provided inside the dishwasher 100. On these disks 13 are a number of blower nozzles 2, which extend at least in a radial direction outwards to the edge of the disk 13.
[0121] FIG. 7 shows a further advantageous embodiment of the air duct system 6 in a vertical and horizontal section, for which in this design the air duct system 6 is represented as a blow-off arm 14. On this blow-off arm 14, which is able to rotate about a rotating axis 16, a number of blower nozzles 2 are also provided.
[0122] FIG. 8 shows yet another advantageous embodiment of the air duct system 6, which in this version is designed as a blow-off arm 14 with eccentric 15. A number of blower nozzles 2 are fitted on this blow-off arm 14 with eccentric 15, e.g. on blower nozzle blocks 21. By designing the blow-off arm 14 as an eccentric 15, this is also moved during a rotary movement by the corners of the dish rack 114 and treats even the dishes placed here with a jet of air L.
[0123] FIG. 9 shows a schematic representation of dishes 3 during the blowing off, in which the dishes 3 are treated by the blower nozzle 2 in the blowing direction R with a jet of air L. This treatment blows the remaining rinsing liquid 10 out of the depression 5 in the dish.
[0124] FIG. 10 shows an advantageous embodiment of a drive 8. In this, the drive 8 is designed as a geared drive, for which two toothed disks 9 are provided, engaging with each other. The rotation axes 91 of the toothed disks 9 are formed as cylindrical hollow bodies, which thus represent a part of the air duct 6. In addition, a rubber ring 92 is provided, which acts in a self-sealing manner on engaging of the toothed disks 9.
[0125] FIG. 11 shows a cross-sectional view of the dishwasher 100 with a further advantageous embodiment of the air duct system 6. In this, the air duct system 6 includes five rails 17, which are equipped with at least one blower nozzle 2 and are configured above a dish rack 114 such that these can treat the dishes 3 in the dish rack 114 reliably with a jet of air L. In addition, placement areas 116 are arranged on the dish rack 114, which are preferably formed as folding mountings 117. In addition, on the side areas adjoining or on the dish rack 114 additional blower nozzles 2 are fitted, which are preferably pointing or can be pointed or angled downwards and with which, for example, dishes 3 under the placement areas 116 can be fed from above or at an angle from above with a jet of air L. Further blower nozzles 2, as depicted on the left, can be fitted to the dish rack 114 and/or the placement areas 116 or, as depicted on the right, on a side rail 18 on a side area of the rinsing area 110.
[0126] FIG. 12 shows a cross-sectional view along a sectional axis Z, which is depicted in FIG. 11. Five rails 17, which are fitted with blower nozzles 2, can be seen in this cross-sectional view. Among other things, these rails 17 can be fitted to the housing 111 of the dishwasher 100 or to a cutlery drawer or to a dish rack 114.
[0127] FIGS. 13a and 13b show schematic vertical sectional drawings of specimen configurations of the pre-drying device 1 in a dishwasher 100, which includes a housing 111, a cutlery drawer 122 and a top and a bottom dish rack 114. The door of the dishwasher 100 is on the right hand side and is not shown. The pre-drying device 1 can be fitted on the underside of the cutlery drawer 122 (FIG. 13a), above the top dish rack 114 on the housing 111, on the bottom of the top dish rack 114 (FIG. 13c) and/or under the top dish rack 114 (FIG. 13d) on the housing 111.
[0128] FIGS. 14a and 14b show schematic vertical sectional drawings of specimen configurations of a height limiter 123 in a dishwasher 100, which includes a housing 111. The door of the dishwasher 100 is on the right hand side and is not shown. The height limiter 123 is arranged in front of the pre-drying device 1, so that dishes in a dish rack that are too high (not shown) will collide when loading the dishwasher 100 with the height limiter 123 and not with the pre-drying device 1. The height limiter can be fitted to the top inside of the housing 111 (FIG. 14a), to the underside of a cutlery drawer 123 (FIG. 14b) and/or to the underside of a dish rack (not shown).
[0129] FIG. 15 shows a schematic representation of a specimen pre-drying device 1 with multiple duct air rails 17. The pre-drying device 1 shown includes an air pressure generating device 120, at whose compressed air outlet is connected a distributor 30, which can also serve as a compressed air tank 121. A sub-distributor 31 is connected to each compressed air output from the distributor 30, to whose compressed air outlets the individual ducts 20 are connected respectively to a multiple duct air rail 17. The outputs from the sub-distributor 31 can be controlled by a joint actuating unit 32, so that individual ducts 20 can be opened concurrently for a number of multiple duct air rails 17. In this way, for example, differently aligned blower nozzles 2 in the multiple duct air rails 17 can be charged sequentially with compressed air, in order to align the emerging air flow on different areas under the pre-drying device 1.
[0130] FIG. 16 shows a schematic perspective drawing of a multiple duct air rail 17. In the air flow upstream of the multiple duct air rail 17, a rotatable perforated disk 29 can be arranged such that a hole 33 in the perforated disk 29 releases a duct 20 of the multiple duct air rail 17, whereas the other ducts 20 are concealed. A rotation of the perforated disk 29 (in the direction of the arrow) powered, for example, by compressed air, can position the hole 33 in front of different ducts 20. In this way, the blower nozzles 2 can deliver a pulsed jet of air to a duct 20 respectively. By inhibiting elements (not shown here), as explained in FIG. 18, the direction of rotation of the perforated disk 29 can be determined and/or its correct positioning in front of the ducts 20 be ensured.
[0131] FIGS. 17a and 17b show schematically a possible design for movable blower nozzles 2. In each case, a blower nozzle 2 is supported on a joint 40, for example a spherical or axial joint, in a movable state (in the direction of the arrow). A gripping control element 41 on the nozzle outlet side of the joint 40, for example a drawbar, allows simultaneous alignment (in the direction of the arrow) of a number of blower nozzles 2. FIG. 17a shows a schematic side view of four blower nozzles 2 connected via a drawbar. FIG. 17b shows a schematic view of an alternative control element 41 in the form of a perforated strap. Through the shape, for example elliptical, of the holes 33 in the perforated strap, which in each case can accommodate the tip of a blower nozzle 2, the tips of the blower nozzle can be moved in a right-to-left movement of the perforated strap both in a right-to-left direction and at right angles to it. In this way, with simple means, the jet of air from each blower nozzle 2 can be aligned on as great an area as possible.
[0132] FIGS. 18a and 18b show schematically a possible design for an air rail 17 with movable blower nozzles 2 in plan view (FIG. 18a) and in cross-section (FIG. 18b) along the axis A-A. In each case, a number of blower nozzles 2 (three in the example shown) is connected rigidly to an inner nozzle head 51, which is pivoted (in the direction of the arrow) on an outer nozzle head 50. The outer nozzle head 50 is connected rigidly to the air rail 17 or as a single part to the air rail 17. The blower nozzles 2 are designed so that the emerging jet of air can rotate the inner nozzle head 51. At the border area between outer nozzle head 50 and inner nozzle head 51, inhibiting elements 53 can be fitted which, for example, in the manner of a ratchet, allow a movement of the inner nozzle head 51 in only one direction and/or end in each case in a pre-defined position. The inhibiting elements 53 can also, for example, include a sphere, supported on springs at the inner nozzle head 51, which is routed to the outer nozzle head 50 with a rotational movement of the inner nozzle head 51 via an arrangement of hollows, similar to saw teeth, with which the sphere engages in each hollow, and the saw tooth shape of the hollows allows only one movement in precisely one direction of rotation. Clearly, it is also conceivable that the sphere is supported on the outer nozzle head 50 and the hollows are fitted to the inner nozzle head 51.
[0133] FIG. 19 shows a schematic view from below a specimen pre-drying device 1. The pre-drying device 1 includes a distributor 30, which can serve simultaneously as a compressed air tank 121. At the compressed air outputs from the distributor 121, air rails 17 are connected in each case via a valve 118. The blower nozzles 2 on the air rails 17 are directed at positions where depressions in the dishes (not depicted) in a dish rack 114 can be found under the air rails 17.
[0134] FIG. 20 shows a schematic perspective drawing of a dishwasher 100. In the housing 111 of the dishwasher 100 shown are connected an air pressure generating device 120 in the form of a compressor and a distributor 30 connected to the compressed air outlet from the compressor, which can serve concurrently as a compressed air tank 121. The distributor 30 has a number of compressed air outputs, to which an air rail 17 in the inner area of the dishwasher is connected via valves 118 in each case. Both the compressed air tank 121 and the inside area 110 each have, in the example shown, a pressure relief valve 124, through which excessive air pressure in the environment of the dishwasher 100 can be discharged.
[0135] FIG. 21 shows a particularly advantageous design of the dishwasher 100 shown in FIG. 20, in which the distributor 30 forms a part of the rear wall of the inner area 110.
[0136] FIG. 22 shows an arrangement of air rails 17 which are connected to a blower nozzle grid 22.
[0137] FIG. 23 shows an air rail 17 connected with a drive 8 in the form of an actuator motor. The drive 8 can move the air rail 17 along its longitudinal axis (in the direction of the arrow) and rotate it about its longitudinal axis (in the direction of the arrow). This is how the blower nozzles 2 fitted on the air rail can be directed at a wide area.
[0138] FIG. 24 shows a schematic cross-sectional view of a dishwasher 100. In the housing 111 of the dishwasher 100 shown are connected an air pressure generating device 120 in the form of a compressor and a distributor 30 connected to the compressed air outlet from the compressor 25, which can serve concurrently as a compressed air tank 121. A compressed air drive 23 and a blower nozzle block 21 with blower nozzles 2 are connected via connecting hoses 26 to the two compressed air outlets from the distributor 30 shown. The compressed air drive 23 moves a movable spindle 24 (in the direction of the arrow) in rotation, whereby the blower nozzle block 21 supported by the spindle 24 is moved along the spindle 24. At least at one end of the spindle 24 is a limit switch 25, which stops the compressed air drive and/or reverses its direction of motion 20 as soon as the blower nozzle block 21 reaches the end of spindle 24.
[0139] FIGS. 25a and 25b show a schematic view of a further design for a spindle drive. Inside a blower nozzle block 21 is a drive 8 in the form of a cylinder fitted to a fixed spindle 24 with a recirculating ball 27, which engages in a groove 28 of the blower nozzle block 21. If the cylinder is moved in rotation (in the direction of the arrow), this guides the blower nozzle block 21 in a straight line along to the spindle 24. FIG. 25b is an enlargement of the blower nozzle block 21 from FIG. 25a.
[0140] FIG. 26 shows a schematic view of an advantageous embodiment of a movable blower nozzle block 21 with blower nozzles 2. The blower nozzle block 21 can be moved along a spindle 24, which can be rotated via a rotation axis 91 fed through an inside wall 110 of a dishwasher 100. The rotation axis 91 is provided at the wall orifice with a seal 92, which prevents water penetrating from the interior 110 to the drive 8 of the spindle 24, which is arranged in the housing 111 of the dishwasher. As additional protection, the blower nozzle block 21 has a cavity H, which surrounds the wall orifice in a rest position of the blower nozzle block 21 and is also sealed at the wall with a seal 92.
[0141] FIG. 27 shows a schematic view of compressed air drive 23 on a spindle 24. The compressed air drive 23 shown has a compressed air inlet E1 for the forward movement along the spindle 24 and a compressed air inlet E2 for the backward movement along the spindle 24.
[0142] FIGS. 28a and 28b show perspective schematic drawings of specimen connection hoses 26. To save space, the connection hoses 26 can be designed as a dual hose (FIG. 28a), which includes two ducts 20, or as a multiple hose (FIG. 28b), which has more than two ducts 20. In each case, a vertical bridge 34, horizontally adjustable, for example a steel tape, in the inside of the connection hoses 26 ensures that the connection hoses cannot sag and at the same time come into contact with the dishes.
[0143] FIG. 29 shows a schematic view of a specimen retractor 35, for example in the style of a cable drum. If a blower nozzle block 21 is moved along a spindle 24 (in the direction of the arrow), the retractor 35, for example by turning (in the direction of the arrow) a drum, always releases a length of connection hose 26 leading from the housing 111 of a dishwasher to the blower nozzle block 21, only large enough so that the latter does not sag. The retractor 35 can be fitted as in the example shown or to or in the housing 111 to save space and advantageously has a vertical retractor axis.
[0144] FIGS. 30a and 30b show in schematic views possible geometries of guide rails 19, on which nozzle blocks 21 in the interior 110 of a dishwasher can move. FIG. 30a shows a particularly simple linearly parallel arrangement of two guide rails 19, on each of which a blower nozzle block 21 can move (in the direction of the arrow). FIG. 30b shows a U-shaped arrangement of a guide rail 19, on which a single blower nozzle block 21 can move over a larger area (in the direction of the arrow).
[0145] FIG. 31 shows a schematic vertical section of a particularly flat blower nozzle block 21. In this way, where fundamentally only the nozzle heads 52 of the blower nozzles 2 jut out from the blower nozzle block 21, a particularly flat and space-saving construction is possible.
[0146] FIG. 32 shows a schematic vertical section through a dishwasher 100, with integrated and concealed nozzle blocks 21. The nozzle blocks 21 are arranged in hollows in the housing 111 of the dishwasher 100 at the top of the interior 110 of the dishwasher 100, in order not to reduce the volume of the interior 110. In this case, the nozzle blocks 21 can for example be moved forwards and backwards at right angles to the plane of the figure, so that the blower nozzles 2 of the nozzle blocks 21 cover the entire depth of the interior 110 with pulsed jets of air. Each blower nozzle block 21 can include differently aligned blower nozzles 2, for example down to the right and down to the left, in order to cover the entire width of the interior 110 with pulsed jets of air. For example, while a blower nozzle block 21 is moving outside the plane of the figure, the blower nozzles 2 pointing to the left can be activated and while moving inside the plane of the figure, those pointing to the right can be activated. Alternatively, the blower nozzles 2 can also fold over at the changeover point of a blower nozzle block movement into an alignment pointing to right or vice versa. A spray wheel 101 for the dishwasher 100 can be arranged between the nozzle blocks to distribute cleaning liquid.
[0147] FIG. 33 shows a schematic view of a breakthrough-free power transfer in the interior 110 of a dishwasher 100. A magnet 60, for example in the form of a magnetic disk, close to a magnetically permeable inside wall section 61, e.g. made from plastic, is moved by a drive 8, e.g. an electric motor. In the interior 110, there is a further magnet 60, which, for example, is connected with a drive spindle 24. Through the magnetic coupling of both magnets 60, a movement of the drive 8 through the unbroken inside wall can be transferred on to the spindle 24, in order, for example, to move a blower nozzle block (not shown). As the inside wall is not broken, no rinsing liquid can leak from the interior 110.
[0148] FIGS. 34a, 34b and 34c show schematically a specimen inhibiting element 53 between an outside nozzle head 50 and an inside nozzle head 51. The inhibiting element includes a sphere 54 connected with the inside nozzle head 51 via a spring-loaded connection 55. The outside nozzle head 50 has a number of hollows V, which are formed such that the sphere 54 can engage in a hollow V, and a movement of outside and inside nozzle heads against each other is possible only in one direction, as illustrated by the sequence of FIGS. 34a-34b-34c. By the spring-loaded connection 55, a movement of outside and inside nozzle heads against one another is possible advantageously without a height offset.
[0149] Although the present invention has been disclosed in the form of preferred embodiments and variations thereon, it will be understood that numerous additional modifications and variations could be made thereto without departing from the scope of the invention.
