Description

[0001] household dishwasher

[0002] The present invention relates to a household dishwasher.

[0003] The operation of household dishwashers (hereinafter also referred to as "dishwashers") is intended to be increasingly simplified. One aspect of this is that a drive moves a dishware holder, such as an upper or lower basket, out of the dishwasher's wash tub for loading and unloading. To improve accessibility, the dishware holder should be moved as far out of the wash tub as possible.

[0004] The document DE 10 2005 010616 A1 discloses a household dishwasher with a drive configured to automatically move a dishware holder out of and into the washing tub. The dishware holder is mounted on telescopic rails and is driven by a gear that engages a rack on the dishware holder.

[0005] The publications WO 2018 / 120924 A1 and WO 2020 / 124970 A1 disclose a household dishwasher with a driven dishware holder, which is attached to the drive via a magnetic device. A fixed threaded rod connected to an electric motor is provided for the drive.

[0006] US 2008 / 0315739 A1 discloses an electrically driven warming drawer designed to move out of and into a cabinet. A rack is attached to the warming drawer, which is driven by a gear of a gearbox mounted on the cabinet.

[0007] Against this background, it is an object of the present invention to provide an improved household dishwasher.

[0008] Accordingly, a household dishwasher is provided with a washing compartment and a dishware receptacle. The household dishwasher further comprises a coupling element that can be moved into and at least partially out of the washing compartment, wherein the dishware receptacle can be moved relative to the coupling element in and against an extension direction between a retracted and extended state. Furthermore, a drive is provided that is configured to drive the coupling element to move it into and out of the washing compartment.

[0009] One idea of ​​the present invention is to provide a driven coupling element that can be moved into and at least partially out of the washing tub, and a dishware holder that can be moved relative to the coupling element. This provides additional extension length for the dishware holder.

[0010] By providing the driven coupling element, the drive can be flexibly positioned along the coupling element. This advantageously allows the drive to be positioned at a greater distance from a door that closes the washing container.

[0011] The "extension direction" is understood to mean in particular a horizontal direction in which the dishware holder is extended.

[0012] A "dishwasher basket" in this context is a basket for holding items to be cleaned, such as plates, cups, cutlery, or bowls. In particular, it can be an upper or lower dishwashing basket, also known as an upper and lower dish basket, or a cutlery drawer.

[0013] A "washing tub" in this context is a container in which one or more washware receptacles can be accommodated. The washing tub has a washing chamber in which the washware is cleaned and dried. The washing tub is preferably cuboid-shaped. According to one embodiment, the washware receptacle, in its extended state, is displaced far enough out from the washing tub that the washware receptacle is spaced from the washing tub in the extension direction.

[0014] This advantageously provides improved accessibility to the contents of the dishware holder.

[0015] A circumferential flange with a seal is attached to the rinsing container, against which the door rests when the rinsing container is closed. The volume enclosed by the closed door and the rinsing container is referred to herein as the rinsing chamber.

[0016] If the dishware holder is spaced apart from the washing container in the extension direction, this preferably means that a rear side of the dishware holder is spaced apart from the circumferential flange in the extension direction (hereinafter also referred to as "over-extension").

[0017] According to a further embodiment, the coupling element is part of a telescopic extension, wherein the telescopic extension further comprises a fixed section which is fastened to the washing container and a movable section which is fastened to the dishware holder, and the coupling element couples the fixed section to the movable section, wherein the coupling element is displaceable with respect to the fixed section and the movable section is displaceable with respect to the coupling element.

[0018] A "telescopic extension" in this case has at least two sections whose profiles partially interlock in the transverse direction. The sections are arranged so they can be moved relative to each other. The telescopic extension allows for a large extension length and a compact design.

[0019] This advantageously allows the driven coupling element to allow the dishware holder to be pulled out completely. A "fixed section" can be understood, in particular, as rollers or wheels that are rotatably mounted on the inside of the dishwashing tub.

[0020] A "fixed section" can also be understood as a rail, such as a telescopic rail, which is attached to the inside of the rinsing container.

[0021] A "movable section" can be understood in particular as rollers or wheels which are rotatably attached to the dishware holder and are translationally displaceable with respect to the coupling element.

[0022] A "movable section" can also be understood as a rail, such as a telescopic rail. The rail is attached to the dishware holder and can be moved translationally relative to the coupling element.

[0023] According to a further embodiment, a carrier element with a gear having a drive side and an output side is fastened to the coupling element, wherein the drive side is operatively connected to the fixed section, so that the fixed section drives the gear when the coupling element is moved in and out.

[0024] To provide the operative connection, a rope, a belt, such as a toothed belt or a V-belt, but in particular a combination of a gear and a rack can be used.

[0025] The term "drive side" of the transmission refers in particular to a side of the transmission which is intended for the torque input into the transmission.

[0026] An "output side" of the transmission is understood to mean, in particular, a side of the transmission which is intended for the torque output from the transmission.

[0027] According to a further embodiment, the output side of the gear unit is operatively connected to the movable section to move the dishware holder between the retracted and extended states. Advantageously, only one drive or motor is required to extend the dishware holder.

[0028] To provide the operative connection, a cable, a belt, such as a toothed belt or a V-belt, or, in particular, a combination of a gear and a rack can be used—as already explained above for the drive side of the transmission. The operative connection is preferably designed as a continuous connection between the dishware holder and the drive.

[0029] According to a further embodiment, the fixed section has a rack, and the rack engages with at least one gear on the drive side of the transmission and / or the carrier element has a rack, and the rack engages with a gear of the drive and / or the dishware holder has a rack which engages with at least one gear on the output side of the transmission.

[0030] This allows a positive torque transmission to be achieved, which means, for example, that the position of the dishwashing basket can be determined via the revolutions of the motor.

[0031] According to a further embodiment, the transmission has at least two, four or six gears which are mechanically arranged in series.

[0032] This allows the extendability of the dishware holder to be extended in the extension direction.

[0033] The term "mechanically arranged in series" gears refers in particular to gears arranged one behind the other in the extension direction, which mesh with the front and / or rear gear.

[0034] The gear mechanism preferably has five gears. The drive and driven-side gears preferably have a larger diameter than the gears between the drive and driven-side gears. According to a further embodiment, a bracket is attached to the movable section, with the dishware holder and the rack being attached to the bracket.

[0035] This advantageously ensures that the bracket and the rack are formed in one piece or in one piece.

[0036] In this context, "one-piece" means that a component is manufactured in one piece in a primary forming step, such as casting, injection molding or extrusion.

[0037] In this case, "one-piece" means that two partner components are connected to each other in a form-fitting and / or force-fitting and / or material-fitting manner.

[0038] According to a further embodiment, the respective displacement of the coupling element and the dishware holder takes place simultaneously.

[0039] According to a further embodiment, the drive comprises an electric motor which is arranged outside the washing container, wherein a shaft of the motor projects into the washing container, and the gear of the drive is fastened on the shaft.

[0040] According to a further embodiment, the support element has two arms which fasten the support element to opposite sides of the coupling element.

[0041] Due to the preferred elongated design of the support element, the support element is attached to two arms. This advantageously prevents bending of the support element and disengages the drive and driven gears from the respective racks of the fixed section and the dishware holder.

[0042] According to a further embodiment, the coupling element and / or the fixed section and / or the movable section each have one or more rails. Rails allow for simple horizontal guidance.

[0043] According to a further embodiment, the rails are arranged so as to be telescopically movable within one another.

[0044] A rail telescopic extension has the advantage of a compact design.

[0045] According to a further embodiment, the rail of the coupling element comprises two C-shaped profiles which are fastened to one another back to back, wherein the profiles are connected to one another offset in the longitudinal direction, wherein the opposite sides of the coupling element are formed at the free ends of the rail, to which the arms of the support element are fastened.

[0046] This results in a compact structure.

[0047] Further possible implementations of the invention also include combinations of features or embodiments described above or below with respect to the exemplary embodiments that are not explicitly mentioned. In this case, the person skilled in the art will also add individual aspects as improvements or additions to the respective basic form of the invention.

[0048] Further advantageous embodiments and aspects of the invention are the subject of the dependent claims and the exemplary embodiments of the invention described below. The invention will be explained in more detail below using preferred embodiments with reference to the accompanying figures.

[0058] Fig. 10 a perspective view of a pre-assembled drivable telescopic extension.

[0059] In the figures, identical or functionally equivalent elements have been given the same reference numerals unless otherwise stated.

[0060] Fig. 1 shows a schematic perspective view of an embodiment of a household dishwasher 1. The household dishwasher 1 comprises a washing container 2, which can be closed, in particular watertight, by a door 3. For this purpose, a sealing device can be provided between the door 3 and the washing container 2. The washing container 2 is preferably cuboid-shaped. The washing container 2 can be arranged in a housing of the household dishwasher 1. The washing container 2 and the door 3 can form a washing chamber 4 for washing dishes.

[0061] The door 3 is shown in its open position in Fig. 1. The door 3 can be closed or opened by pivoting about a pivot axis 5 provided at a lower end of the door 3. With the help of the door 3, a loading opening 6 of the washing compartment 2 can be closed or opened. The washing compartment 2 has a base 7, a ceiling 8 arranged opposite the base 7, a rear wall 9 arranged opposite the closed door 3, and two side walls 10, 11 arranged opposite one another. The base 7, the ceiling 8, the rear wall 9 and the side walls 10, 11 can be made, for example, from a stainless steel sheet. Alternatively, the base 7 can be made, for example, from a plastic material. The household dishwasher 1 further has at least one dishware holder 12 to 14.Preferably, several, for example three, dishware receptacles 12 to 14 can be provided, wherein the dishware receptacle 12 can be a lower dishware receptacle or a lower basket, the dishware receptacle 13 can be an upper dishware receptacle or an upper basket, and the dishware receptacle 14 can be a cutlery drawer. As Fig. 1 further shows, the dishware receptacles 12 to 14 are arranged one above the other in the washing container 2. Each dishware receptacle 12 to 14 can be selectively moved into or out of the washing container 2. In particular, each dishware receptacle 12 to 14 can be pushed or moved into the washing container 2 in an insertion direction E (arrow) and pulled or moved out of the washing container 2 in an extension direction A (arrow) opposite to the insertion direction E (arrow).

[0062] Fig. 2 shows an extended telescopic pull-out 15 with a coupling element 16, a fixed section 17 and a movable section 18. The coupling element 16 couples the fixed section 17 to the movable section 18. The fixed section 17 is fastened to the side wall 10, 11. The dishware holder 13 is fastened to the movable section 18. The coupling element 16 is displaceable relative to the fixed section 17 in the longitudinal direction L (double arrow). The movable section 18 is likewise displaceable relative to the coupling element 16 in the longitudinal direction L (double arrow) (corresponding to the extension / retraction direction A (arrow), E (arrow) in Fig. 1). The fixed section 17 and the movable section 18 are designed as rails in the present case. The rails 17, 18 each have a C-profile. The rails 17, 18 are made of stainless steel or a plastic material, for example.

[0063] The fixed section 17 can, for example, be designed as wheels or rollers instead of a rail, which are rotatably attached to the side wall 10, 11. The movable section can, for example, be designed as wheels or rollers instead of a rail, which are rotatably attached to the dishware holder 12. On the lowest dishware holder 12, the wheels can be guided, for example, on the door 3 in order to move the dishware holder 12 in and out. The coupling element 16 is illustrated in Fig. 4. The coupling element 16 has two rails 19, 20. Fig. 3 shows a cross-section of the rails 19, 20 when the telescopic extension 15 is retracted. The rails 19, 20 each have a C-profile and a back side 21, 22. The rails 19, 20 are fastened to one another back or back side 21 to back or back side 22, wherein they are fastened offset from one another in the longitudinal direction L (double arrow).The rail 19 is fastened in front of the rail 20 in the extension direction A (arrow). As can be seen in Fig. 3, the rail 20 engages around the rail 17 so that the rail 20 is guided by the rail 17 and the rails 20, 17 can be moved into one another. The rail 18 engages around the rail 19 so that the rail 19 is guided by the rail 18 and the rails 18, 19 can be moved into one another. For better guidance in the longitudinal direction L (double arrow) on the rails 17, 18, the rails 19, 20 include, for example, a linear ball bearing or a plain bearing. The rails 19, 20 are made of, for example, stainless steel or a plastic material.

[0064] Fig. 4 further shows a support element 23. The support element 23 has an elongated shape with a front and rear end in the longitudinal direction L (double arrow). At the ends, on the upper edge in the vertical direction H (arrow), two arms 24, 25 are formed. The arms 24, 25 extend in the vertical direction H (arrow) and fasten the support element 23 to the coupling element 16. The arm 25 is fastened to a back 21 of the free end of the rail 19. The arm 24 is fastened to the back of the free end of the rail 20. The arms 24, 25 each have, for example, two kinks 26 in the longitudinal direction L (double arrow). Along the kinks 26, the arms 24, 25 are folded toward the support element 23 in such a way that the rails 17, 18 on the coupling element 16 can be freely displaced beyond the arms 24, 25 in the longitudinal direction L (double arrow). This advantageously prevents a collision of the arms 24, 25 with the rails 17, 18.Furthermore, the support element 23 is arranged closer to the side wall 10, 11 (Fig. 1) that is closest to the support element 23. This advantageously enables a compact design.

[0065] The support element 23 is made, for example, from a sheet metal or a plastic plate. A section 27 of the support element 23 is folded over at a lower end of the support element 23. A rack 28 is attached to the folded section 27 and is driven, as will be explained in more detail later. The rack 28 is made, for example, from a plastic material. The support element 23 has four circular holes 29, in each of which a gear is rotatably mounted, as will be explained in more detail later. Depending on the number of gears, the support element 23 can also have more or fewer than four holes 29.

[0066] Fig. 5 shows the telescopic pull-out 15 with the dishware holder 13 from Fig. 1 in a side view. A drive 30 is provided to move the dishware holder 13 out of and into the washing tub 2. As shown in Fig. 6, the drive 30 comprises a motor 31, which is located outside the washing tub 2 and has a shaft 32 that extends into the washing tub 2. A gear in the form of a pinion 33 (also referred to herein as a "gear") is attached to the shaft 32 of the motor 31.

[0067] Returning to Fig. 5, the pinion 33 engages with the rack 28 of the support element 23 and drives the support element 23. As a result, the coupling element 16 with the support element 23 is moved into and out of the washing container 2.

[0068] As further shown in Fig. 5, a gear 34 is arranged on the carrier element 23. The gear 34 comprises four gears 35 to 38, which are arranged one behind the other in the extension direction A (arrow). Furthermore, the gears 35 to 38 are mechanically arranged in series. In further exemplary embodiments, the gear 34 comprises two or six gears, which are mechanically arranged in series. The gears 35 to 38 are arranged on the side of the carrier element 23 which faces away from the side wall 11. The gears 35 to 38 are in engagement with the respective front gear. In this case, the gear 35 is the rear gear in the extension direction A (arrow) and the gear 38 is the front gear in the extension direction A (arrow). The gears 35 to 38 are made, for example, from a plastic material.

[0069] As illustrated in Fig. 7, the gear 34 comprises a further gear 39, which is provided on the side of the support element 23 facing the side wall 11. The gear 39 drives the gear 35 via a shaft 40. The gear 39 and the shaft 40 are made, for example, from a plastic material. The gear 34 further comprises a drive side AN and an output side AB. The gear 39 is the drive-side gear AN of the gear 34, as will be explained in more detail later. Returning to Fig. 5, it is shown that the gear 38 is the output-side gear AB of the gear 34. The gears 36, 37 provide further spacing in order to increase the maximum extension length of the dishware holder 13. In further embodiments, instead of the two gears 36, 37, more gears, for example four or six gears, can be arranged between the rear and front gears 35, 38.With the same diameter, multiple gears can increase the maximum extension length of the washware holder 13. To increase the maximum extension length, the diameter of gears 35 to 38 can also be increased, for example. Instead of gears 35 to 37, a belt drive can also be provided to further increase the extension length. Gears 36 and 37 are all optional.

[0070] As illustrated in Fig. 10, a rack 41 is attached to the rail 18. The rack 41 engages with the output-side gear 38 of the gear 34 and drives the rail 18. This causes the rail 18 to extend and retract relative to the coupling element 16. The rack 41 is made, for example, of a plastic material.

[0071] Furthermore, a front and a rear bracket 42, 43 are provided on the rail 18 in order to fasten the dishware holder 13 to the rail 18. The dishware holder 13 has a plurality of rods or wires which are clipped into the brackets 42, 43 and thereby fasten the dishware holder 13 to the rail 18. The front bracket 42 is arranged in front of the rear bracket 43 in the extension direction A (arrow). The front bracket 42 is plugged onto the front end of the rail 18 in the extension direction A (arrow). The rear bracket 43 is clipped onto the rail 18 in the rear third of the same. The rear bracket 43 is connected to the rack 41. To improve stability, the rack 41 is additionally clipped to the rail 18 in the front half of the rail 18 in the longitudinal direction L (double arrow).The rear bracket 43 and the rack 41 are, for example, manufactured in one piece as an injection-molded part from a plastic material, but can also be manufactured in multiple pieces. The front and rear brackets 42, 43 can, for example, be formed in one piece with the rack 41. Fig. 7 shows the driven telescopic pull-out 15 with the dishware holder 13, now from a rear view. A rack 44 is attached to the rail 17. The rack 44 engages with the drive-side gear 39 of the gear 34. The gear 39 is driven by the inward and outward displacement of the coupling element 16.

[0072] Fig. 8 shows the driven telescopic pull-out 15 with the dishware holder 13 in a retracted state. If the motor 31 is actuated, for example, by an operator via a control element or automatically, the shaft 32 of the motor 31 is set in rotational motion and torque is transmitted to the shaft 32 of the motor 31. The shaft 32 of the motor 31 transmits the torque and the rotational movement to the pinion 33. Because the pinion 33 engages with the rack 28 of the support element 23, the rotational movement of the pinion 33 is converted into a translational movement of the support element 23. The coupling element 16 is moved out of the wash tub 2. As a result, the rack 44 drives the drive-side gear 39 of the gear 34. This means that the translational movement of the coupling element 16 is converted into a rotational movement of the gear 39. The gear 39 in Fig.7 drives the gear 35 via the shaft 40 and thus the gears 36 to 38 on the other side of the support element 23. The gears 35 and 37 rotate in the opposite direction to the gears 36 and 38. The gear 38 must rotate in the opposite direction to the gear 38 so that the dishware holder 13 is moved out of the washing container 2. The output-side gear 38 of the gear 34 drives the rack 41 and converts the rotational movement of the gear 38 back into a translational movement. As a result, the rail 18 with the dishware holder 13 is moved out of the washing container 2.

[0073] Due to a direct operative connection between the coupling element 16 and the dishware holder 13, the displacement of the coupling element 16 and the dishware holder 13 occurs simultaneously.

[0074] Fig. 9 shows the driven telescopic pull-out 15 with the dishware holder 12 in an extended state with a circumferential flange 45 of the washing container 2 that delimits the front loading opening 6. A seal 46 is attached to the circumferential flange 45, against which the door 3 rests when the washing container 2 is closed. As Fig. 9 further shows, a rear wall 47 of the dishware holder 13 is spaced from the flange 45 of the washing container 2. The rear wall 47 of the dishware holder 13 is a basket side wall, which is formed in particular from rods or wires of the dishware holder 13.

[0075] The distance between the rear wall 47 of the washware holder 13 and the flange 45 of the wash tub 2 is designated C in Fig. 9. The distance C can be, for example, 10 cm or more. As described above, the distance C can be increased by a larger diameter of the gears 35 to 38 and / or with additional gears arranged between the gears 35 to 38.

[0076] In a further embodiment, the coupling element 16 can be driven via belts, such as toothed belts or V-belts. In a further embodiment, the coupling element 16 can be driven via cables and pulleys.

[0077] In a further embodiment, the driven telescopic extension 15 from Fig. 9 can be pre-assembled. In a further assembly step, it can be attached to an inner side of the rinsing container 2.

[0078] Although the present invention has been described using exemplary embodiments, it can be modified in many ways.
