Description

The present invention relates to a household appliance, in particular a water-bearing household appliance.

Many household appliances, such as household dishwashers, include a pivoting door. Furthermore, the household appliance can include a device that can compensate for the weight of the door in order to prevent the door from falling down in the open position. For this purpose, the device comprises, for example, a rope which is connected at one end to the door and at its other end to a spring element. The spring element in turn is connected to a housing of the household appliance, for example. During an opening movement of the door, for example, the spring is prestressed so that a spring force acts on the door with the aid of the cable in such a way that the door is prevented from falling down. Furthermore, friction elements can be provided, which make it difficult for the door to pivot. A corresponding frictional force can form a difference between the weight of the door, which pulls on the cable, and the spring force when the door is in the open position.

The EP 0 541 974 A1 shows, for example, a dishwasher with an appliance housing in which an electric motor drive is provided. With the help of the electric motor drive, for example, an appliance door of the dishwasher can be completely or partially closed or opened.

Against this background, an object of the present invention is to provide an improved household appliance.

Accordingly, a household appliance is provided with a housing, a door which is pivotably connected to the housing by means of a hinge and comprises a lever, a cable which is connected at one end to the lever, a motor and a cable drum on which the The cable can be at least partially wound up and from which the cable can be at least partially unwound, the cable and the motor being set up to bring about a pivoting movement of the door by winding the cable onto the cable drum or by unwinding the cable from the cable drum.

By using a cable drum, a particularly space-saving arrangement can be provided. For example, the pivoting movement of the door can be influenced directly with the help of the cable drum. A robust door opening mechanism can advantageously be provided as a result, since, for example, direct power transmission from the cable drum to the cable that pulls on the door is possible. In addition, a household appliance can be provided in which an automatic door pivoting movement can be implemented with a small number of components. The household appliance is preferably a household dishwasher, a washing machine, a refrigerator, preferably a refrigerator, or an oven. The housing is preferably an outermost housing of the household appliance, at least in sections. The housing preferably comprises a base housing and a flushing container arranged on the base housing. The floor housing comprises, for example, a floor, two opposite outer walls and a rear wall arranged opposite the closed door. The base, the outer walls and the rear wall of the base housing are preferably connected to one another and form an essentially cuboid geometry. According to the invention, the door is connected to the housing by means of a hinge. For example, the door is pivoted toward a floor on which the household appliance is standing. According to the invention, the door comprises a lever to which one end of the cable is connected. For example, another end of the cable is connected to the cable drum. The motor is, for example, an electric motor. For example, the motor, the cable and the cable drum are provided redundantly and arranged accordingly along the two outer walls of the housing.

In the present case, “rope drum” means, for example, a rotatably mounted pulley that is set up in such a way that the rope can be wound onto the pulley or unwound from the pulley. In this context, "winding up" means increasing a contact surface between the cable and the cable drum and/or that cable sections are placed on other sections of the cable so that a spiral shape is formed. Here, "unwinding" means reducing the contact surface between the rope and the rope drum and/or that rope sections are detached from other sections of the rope. For example, an angle of wrap of the cable around the cable drum is reduced during unwinding, and the angle of wrap of the cable around the cable drum is increased during winding. Thereby can the wrap angle is greater or less than 360°. For example, by winding the rope onto the rope drum, one end of the rope is pulled so that the lever of the door is pivoted, thereby rotating the door about the hinge. The cable preferably comprises plastic and/or metal. Alternatively or additionally, the rope can include yarn and/or textiles, in particular natural fibers and/or chemical fibers. For example, the cable is formed from several cable sections that are mechanically connected to one another.

According to one embodiment, the cable drum is drive-connected to the motor and/or flanged to the motor.

As a result, the cable drum can be driven or rotated directly with the help of the motor. Furthermore, the cable drum and the motor are arranged in a space-saving manner. For example, the motor includes a drive shaft on which the cable drum sits. The motor is preferably firmly connected to the housing. For example, the cable drum and motor can also be referred to as a cable winch.

According to a further embodiment, the household appliance comprises a further cable which is connected to the door at one end, the cable and the further cable being able to be wound up synchronously at least partially onto the cable drum and at least partially unwound from the cable drum, the cable that additional cable and the motor are set up to bring about the pivoting movement of the door by winding the cable and the additional cable onto the cable drum or unwinding the cable and the additional cable from the cable drum, with the cable running from a first section of the cable drum to a Outer wall of a floor housing, around a deflection pulley and then along the outer wall towards the door, and wherein the further cable runs from a second section of the cable drum to a further outer wall of the floor housing, around a further deflection pulley and then along the further outer wall runs to the door.

It is advantageous that two power drive points can be created on the door with the help of the cable drum, the cable and the additional cable. In particular, a secure pivoting movement of the door can thereby be implemented, for example. Furthermore, tilting of the door can be prevented. In addition, an asymmetrical pivoting movement counteract the door. For example, one end of the additional cable is connected to an additional lever of the door and the other end of the additional cable is connected to the cable drum. The cable drum preferably comprises a first section onto which the cable can be wound or from which the cable can be unwound. Furthermore, the cable drum comprises, for example, a second section onto which the additional cable can be wound or from which the additional cable can be unwound. The first section and the second section of the cable drum are preferably arranged coaxially. For example, the first section and the second section of the cable drum are designed identically and are firmly connected to one another. Furthermore, the first and second sections of the cable drum can be made of one piece of material.

According to a further embodiment, the domestic appliance comprises a spring element which is set up to at least partially compensate for a weight of the door.

This has the advantage that an uncontrolled opening of the door can be avoided. Furthermore, manual closing of the door is made easier. The spring element is preferably a helical spring. For example, a spring characteristic of the spring element is progressive, degressive or linear. For example, when the opening angle of the door increases, the spring element is lengthened and thereby prestressed. The domestic appliance preferably also includes a friction element which is set up to apply a frictional force to the cable. For example, such a frictional force corresponds to a difference between the weight of the door, which pulls on the cable and optionally on the additional cable, and the spring force. For example, with the help of the friction element, the door can assume a stationary position at any opening angle. Since the weight of the door is at least partially compensated with the help of the spring element, a motor with a low motor power can be used.

According to a further embodiment, the household appliance includes a rotation element which is set up to tension the spring element.

It is advantageous that the spring element can be tensioned or released with the aid of a rotational movement, thereby creating a space-saving arrangement. For example, one end of the spring element is directly connected connected to the rotation element. For example, the other end of the spring element is connected to the housing. For example, the rotating element and the cable drum are drive-connected to one another.

According to a further embodiment, the household appliance comprises an auxiliary cable, with the rotary element being designed as an auxiliary cable drum, with the auxiliary cable being able to be at least partially wound onto the auxiliary cable drum and at least partially unwound from the auxiliary cable drum and being connected at one end to the spring element.

Advantageously, an indirect connection (cable connection) can be formed between the rotating element and the spring element with the help of the auxiliary cable. The auxiliary cable drum is preferably arranged coaxially with the cable drum. For example, the auxiliary cable drum is firmly connected to the cable drum. The auxiliary rope drum and the rope drum can be designed as a single rope drum. For example, the cable drum and the auxiliary cable drum are set up to wind up the cable and simultaneously unwind the auxiliary cable or to unwind the cable and simultaneously wind up the auxiliary cable. In this case, for example, the auxiliary rope and the rope are wound up or unwound parallel to one another. Furthermore, using the rope drum and the auxiliary rope drum has the advantage that preferably no slippage occurs between the rope and the rope drum and/or between the auxiliary rope and the auxiliary rope drum.

According to a further embodiment, the rotation element is designed as a lever which is drive-connected to the cable drum and connected to the spring element.

The use of a lever has the advantage, for example, that the spring element can be connected directly to the lever and, for example, an auxiliary cable can thereby be dispensed with. For example, the lever and the cable drum are made as an integral injection molded component. For example, the rope drum and the lever are configured to rotate about the same central axis.

According to a further embodiment, a first end of the spring element is connected to another end of the cable and a second end of the spring element is connected to the motor and/or the cable drum.

The spring element is thus arranged, for example, between the cable and the motor and/or the cable drum.

According to a further embodiment, the domestic appliance includes a clutch which is set up to disconnect a drive connection between the motor and the cable drum and/or the cable.

Advantageously, the motor can be decoupled from the pivoting movement of the door with the aid of the clutch. For example, such a decoupling can be referred to as an idle circuit. For example, this can protect the motor and/or reduce resistance to manual movement of the door. The clutch is preferably set up to be triggered when a door limit resistance is exceeded, so that the drive connection between the motor and the cable drum and/or the cable is separated. For example, such a door limit resistance is achieved when an object is trapped between the housing and the door. Advantageously, a safety device can be created by which crushing can be avoided. This reduces the risk of injury at shearing and clamping points. For example, the clutch is designed as a slipping clutch or separating clutch.

According to a further embodiment, the household appliance comprises a control device which is set up to activate the motor in such a way that a pivoting movement of the door is brought about.

In this way, for example, a fully automatic pivoting movement of the door can advantageously be implemented. For example, the control device and the motor are coupled to one another in terms of signals. The control device is preferably set up to control a complete opening movement of the door. Furthermore, the control device can be set up, for example, to control a complete closing movement of the door. For example, the control device is connected to the clutch in terms of signals. In this case, the control device can be set up to actuate the clutch, in particular the separating clutch. For example, the controller set up to control the motor for opening the door in order to counteract the formation of odors within the household appliance.

According to a further embodiment, the control device is set up to switch the motor to generator operation in order to generate a resistance against the pivoting movement of the door.

A haptic feedback on the door can advantageously be optimized as a result. For example, the difference between the weight of the door pulling on the cable and the spring force can be compensated for with the help of the resistance.

According to a further embodiment, the household appliance includes an operator interface that is set up to communicate with the control device.

This has the advantage that different opening or closing functions of the door can be implemented in the household appliance. For example, the operator interface includes a push button, a touch display, a microphone, or some other input device or output device. Furthermore, the operator interface can include a sensor that is set up to detect an operator input, in particular a gesture by the operator.

According to a further embodiment, the domestic appliance comprises an output device which is set up to output an acoustic signal and/or optical signal during the pivoting movement of the door.

This has the advantage that people who are in the vicinity of the household appliance are warned with the aid of the acoustic signal and/or visual signal. In this way, for example, unwanted collisions between the door and the people can be avoided. The output device preferably includes a loudspeaker for outputting the acoustic signal and/or a light source for outputting the optical signal.

According to a further embodiment, the household appliance includes a parking brake which is set up to prevent a winding-up and/or unwinding movement of the cable drum and/or the pivoting movement of the door.

For example, the parking brake is set up to prevent the door from moving forward. The parking brake is preferably connected to the control device in terms of signals.

Furthermore, a household appliance is proposed, with a housing, a door that is pivotably connected to the housing, a spring element, a cable that is connected at one end to the door and at its other end to the spring element, and a linear drive that is connected to the Housing is fixed, is directly connected to the spring element and is adapted to move the spring element to cause a pivoting movement of the door.

A compact door opening mechanism can be provided with the aid of the linear drive, which is directly connected to the spring element. Furthermore, a simple and clear mechanism of action can be provided. The linear drive preferably comprises a spindle drive or the linear drive is designed as a spindle drive. The advantages and embodiments mentioned for the household appliance with the cable drum apply correspondingly to the household appliance comprising the linear drive.

1 shows a schematic perspective view of a household appliance 1. The household appliance 1 is, for example, a domestic dishwasher. Alternatively, the household appliance 1 can be designed as a washing machine, a refrigerator, for example a refrigerator, or as an oven. The household appliance 1 includes a washing compartment 2, which can be closed by a door 3, which is in particular watertight. For this purpose, a sealing device can be provided between the door 3 and the washing container 2 . The washing compartment 2 is preferably cuboid. The rinsing container 2 is in a housing 16 (only partially shown) of the household appliance 1 arranged. The washing compartment 2 and the door 3 can form a washing chamber 4 for washing items to be washed.

Door 3 is in the 1 shown in their open position. 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 plate 7, a cover 8 arranged opposite the base plate 7, a rear wall 9 arranged opposite the closed door 3 and two side walls 10, 11 arranged opposite one another. The floor panel 7, the ceiling 8, the rear wall 9 and the side walls 10, 11 can be made of sheet steel, for example. In particular, for example, the floor panel 7 can be made of a different material than the cover 8 and the side walls 10, 11. For example, the floor panel 7 can be made of the material 1.4301, the cover 8 and the side walls 10, 11 can be made of the material 1.4016 and the rear wall 9 also be made of the material 1.4916.

A first side wall 10, a second side wall 11 and the cover 8 arranged between the first side wall 10 and the second side wall 11 are made in one piece, in particular in one piece of material, and form a washing container casing 12 of the washing container 2. The washing container casing 12, the rear wall 9 and the floor panel 7 are components that are manufactured separately from one another, but are connected to one another in a watertight manner. The rinsing container 2 is arranged on a base housing 63 and connected to it. The household appliance 1 includes a housing 16 which includes the base housing 63 and the washing compartment 2 . The bottom housing 63 comprises a bottom 50, two outer walls 37, 41 (see figure 5 ) and a rear wall 36 arranged opposite the closed door 3 (see figure 5 ).

The domestic appliance 1 also has at least one washware holder 13 to 15 . Preferably, several, for example three, washware holders 13 to 15 can be provided, with the washware holder 13 being a lower washware holder or a lower rack, the washware holder 14 being an upper washware holder or an upper rack and the washware holder 15 being a cutlery drawer. As the 1 further shows that the washing items receptacles 13 to 15 are arranged one above the other in the washing compartment 2 .

Each wash item holder 13 to 15 can be moved either into or out of the washing container 2 . In particular, each washware receptacle 13 to 15 can be pushed into the washing compartment 2 in an insertion direction E and pulled out of the washing compartment 2 in a pull-out direction A counter to the insertion direction E.

Instead of the rinsing container 2, a washing container, a cooling container or a cooking container can also be provided.

2 shows a schematic side view of a further embodiment of the household appliance 1. The household appliance 1 comprises the housing 16 and the door 3, which is pivotably connected to the housing 16 with the aid of a hinge 20. Furthermore, the door 3 includes a lever 21 which protrudes into an interior space 22 of the housing 16 . By moving the lever 21, the entire door 3 can be opened and closed about the pivot axis 5, which runs through the hinge 20. Furthermore, the household appliance 1 includes a cable 17 which is connected to the lever 21 at one end 18 . In addition, the household appliance 1 includes a motor 19 which is connected to the housing 16 or the washing compartment 3 (see FIG 1 ) is connected, and a cable drum 23 onto which the cable 17 can be at least partially wound up and from which the cable 17 can be at least partially unwound. The cable 17 and the motor 19 are set up to bring about a pivoting movement of the door 3 by winding the cable 17 onto the cable drum 23 or by unwinding the cable 17 from the cable drum 23 . For example, the cable drum 23 is drive-connected to the motor 19 . The motor 19 is set up to cause the cable drum 23 to rotate. For example, a second end 24 of the cable 17 is firmly connected to the cable drum 23 .

3 shows a schematic side view of another embodiment of the household appliance 1. In contrast to 2 the household appliance 1 includes a spring element 25 which is designed to at least partially compensate for a weight G of the door 3 . Furthermore, the household appliance 1 comprises a rotation element 26, which is set up to tension the spring element 25 (rotation element 26 in 3 not visible). For example, the rotating element 26 is rigidly connected to the cable drum 23 . When the cable drum 23 rotates, the rotating element 26 would therefore also rotate.

Furthermore, the household appliance 1 includes an auxiliary cable 27 which is connected to the rotating element 26 . The auxiliary rope 27 is connected at one end 28 to one end 29 of the spring element 25 . Furthermore, the other end 30 of the spring element 25 is connected to the housing 16 . The spring element 25 can thus be tensioned with the aid of the auxiliary cable 27 . The auxiliary cable 27 is thereby released or pulled with the aid of the rotary element 26 . When the auxiliary cable 27 is pulled, the spring element 25 is lengthened and thus prestressed. When the auxiliary cable 27 is released, the spring element 25 contracts again. The household appliance 1 also includes a friction element 31 on which the cable 17 rubs. A frictional force is thereby generated in order to inhibit an unwanted pivoting movement of the door 3 . This is particularly helpful when a tensile force in the cable 17 due to the weight G of the door 3 exceeds a spring force or the spring force exceeds the tensile force in the cable 17 due to the weight G. In the event that the entire system is in a balance of forces, a one-sided application of force to the lever 21 is sufficient, for example, to bring the entire door 3 out of the rest position. Instead of the friction element 31, a deflection roller can also be provided.

The household appliance 1 also includes a control device 32 which is set up to control the motor 19 in such a way that the door 3 carries out the pivoting movement. The control device 32 is coupled in terms of signals to the motor 19 (indicated by dashed lines). For example, the control device 32 is set up to switch the motor 19 to generator operation in order to generate a resistance against the pivoting movement of the door 3 . In this way, for example, haptic feedback for an operator who manually executes the pivoting movement of the door 3 can be improved. For example, the household appliance 1 includes a user interface 33 that is set up to communicate with the control device 32 . The operator interface 33 may include, for example, a push button, touch display, microphone, sensor, or other input or output device. The operator interface 33 is coupled in terms of signals to the control device 32 (indicated by dashed lines). Furthermore, the household appliance 1 can include a sensor 34 which is arranged, for example, in the door 3 or in the hinge 20 and is set up to detect the pivoting movement of the door 3 . The sensor 34 is also connected to the control device 32 in terms of signals (indicated by dashed lines). For example, using the operator interface 33 and / or the sensor 34, an automatic Closing the door 3 can be realized with the help of a foot touch by the operator or with the help of a detection of a foot position or foot gesture of the operator. Furthermore, it is conceivable to initiate a full closing or full opening of the door 3 using an app control. For example, the closed door 3 opens with the help of a pressure input by the operator of the household appliance 1. For example, the door 3 is pressed down or up in any position and the door movement then automatically continues. Provision can also be made, for example, for the opening of the door 3 to be initiated with the aid of an actuation of the operator interface 33, in particular a button actuation.

Furthermore, the household appliance 1 can include an output device 35 which is set up to output an acoustic signal during the pivoting movement of the door 3 . The output device 35 comprises a loudspeaker, for example. For example, the output device 35 is coupled in terms of signals to the control device 32 (indicated by dashed lines).

The cable 17 and/or the lever 21 and/or the cable drum 23 and/or the motor 19 and/or the rotating element 26 and/or the auxiliary cable 27 and/or the spring element 25 can be designed, for example, as described above or below and redundantly , especially along the side wall 10 (see 1 ) and along the side wall 11 (see 1 ), be provided.

4 shows a partial section IV - IV 1 , which runs horizontally through the household appliance 1. The bottom housing 63 includes the outer wall 37. Furthermore, the rotating element 26 is designed as an auxiliary cable drum 38. The auxiliary rope drum 38 is firmly connected to the rope drum 23 . In this case, for example, the auxiliary rope drum 38 and the rope drum 23 can be configured identically. For example, the cable drum 23 and the auxiliary cable drum 38 can be designed as a double cable drum. In particular, the rope drum 23 and the auxiliary rope drum 38 are made of metal or plastic. For example, the cable drum 23 and the auxiliary cable drum 38 are arranged coaxially and can be rotated about a central axis M. In particular, the cable drum 23 and the auxiliary cable drum 38 can be rotationally symmetrical with respect to the central axis M. For example, the auxiliary rope 27 can be at least partially wound up on the auxiliary rope drum 38 and can be at least partially unwound from the auxiliary cable drum 38 and is connected at one end 28 to the spring element 25 .

The motor 19 is connected, for example, to the outer wall 37 and is arranged coaxially with the cable drum 23 and with the auxiliary cable drum 38 . For example, the cable drum 23 and the auxiliary cable drum 38 are mounted on the motor 19, with a clutch 39 being arranged between the cable drum 23 and the motor 19. For example, the clutch 39 is set up to disconnect a drive connection between the motor 19 and the cable drum 23 and/or the cable 17 . The clutch 39 is a slip clutch, for example. For example, the cable drum 23 can be flanged to the motor 19 .

figure 5 shows a further embodiment of the household appliance 1 in a schematic top view. The household appliance 1 comprises a further cable 42 which is connected at one end 44 to a further lever 43 of the door 3, the cable 17 and the further cable 42 being synchronous at least partially wound onto the cable drum 23 and at least partially unwound from the cable drum 23 . The cable 17, the additional cable 42 and the motor 19 are set up to direct the pivoting movement of the door 3 by winding the cable 17 and the additional cable 42 onto the cable drum 23 or by unwinding the cable 17 and the additional cable 42 from the cable drum 23 cause. The cable drum 23 includes a first section 45 from which the cable 17 can be unwound. Furthermore, the cable drum 23 includes a second section 46 from which the additional cable 42 can be unwound. The first section 45 and the second section 46 are arranged side by side and coaxially with the central axis M. For example, the second section 46 is integrally formed onto the first section 45 . The first section 45 and the second section 46 can be configured identically, for example.

The cable 17 runs from the first section 45 to the outer wall 37, runs around a deflection pulley 47 and then runs along the outer wall 37 to the door 3. The cable 17 is preferably deflected by 90° by means of the deflection pulley 47. The other cable 42 runs from the second section 46 to the outer wall 41, runs around a deflection roller 48 and then runs along the outer wall 41 to the door 3. The deflection preferably takes place with the aid of the deflection roller 48 by 90°. Advantageous is that by means of a single motor 19, two cables 17, 42 are unwound and wound, each fixed to the door 3. In addition, the auxiliary cable drum 38 is also driven with the aid of the motor 19, with the aid of which the spring element 25 can be tensioned and relaxed in order to compensate for the weight G of the door 3.

Furthermore, the household appliance 1 includes a parking brake 49 which is set up to prevent a winding-up movement and/or an unwinding movement of the cable drum 23 and/or the pivoting movement of the door 3 . For example, the parking brake 49 is arranged between the motor 19 and the cable drum 23 . Alternatively, the parking brake 49 can also be provided in the motor 19 . For example, the parking brake 39 can be used to fix a certain opening angle of the door 3 .

The motor 19, the cable drum 23 and the auxiliary cable drum 38 can be provided centrally in the household appliance 1. The central axis M thus runs through a vertical plane K, which divides the household appliance 1 into two halves of equal size. Furthermore, the auxiliary rope 27 runs from the auxiliary rope drum 38 to the outer wall 37 , the auxiliary rope 27 being connected to the outer wall 37 with the aid of the spring element 25 . Alternatively, the auxiliary cable 27 can run to the outer wall 41 and be connected to the outer wall 41 by means of the spring element 25 . In addition, the central axis M runs from the closed door 3 to the rear wall 36. The motor 19 and/or the cable drum 23 and/or the auxiliary cable drum 38 and/or the cable 17 and/or the additional cable 42 and/or the auxiliary cable 27 and/or the spring element 25 can be installed, for example, between the floor 50 of the floor housing 63 and the floor panel 7 (see 1 ) of the washing tank casing 12 can be arranged.

6 shows a further embodiment of the household appliance 1 viewed in a schematic plan view figure 5 the central axis M runs vertically upwards from the floor 50 to the ceiling 8 (see 1 ). This means that at least the motor 19 and the cable drum 23 have a different orientation than in FIG figure 5 shown. In addition, the rotating element 26 is designed as a lever 51 . The lever 51 is rigidly coupled to the cable drum 23 and rotates about the central axis M when the cable 17 is wound and/or unwound. The lever 51 is connected with its one end 52 to the cable drum 23 and is fixed with its other end 53 to one end 29 of the spring element 25 . Thus, the lever 51 is drive-connected to the cable drum 23 and connected to the spring element 25. A pivoting movement of the lever 51 is effected with the aid of the motor 19 and the spring element 25 is thus tensioned and/or relieved.

7 shows a further embodiment of the household appliance 1 in a schematic plan view 6 no rotating element 26 is provided. Furthermore, the cable 17 has an interrupted area 54 in which the spring element 25 is arranged. In other words, the rope 17 is divided into a first rope section 55 and a second rope section 56 which are connected with the aid of the spring element 25 . The spring element 25 is connected to the door 3 with the aid of the second cable section 56 . In analogy to this, the further cable 42 has an interrupted area 57 in which a further spring element 58 is arranged. In other words, the additional cable 42 is divided into a first cable section 59 and a second cable section 60 which are connected to one another with the aid of the additional spring element 58 .
