Description

The present invention relates to a domestic dishwasher.

A dishwasher has a rinsing container and at least one dishwashing basket which can be moved into and out of the rinsing container. The dishwasher may have a plurality of stacked baskets, such as a lower basket, an upper basket and a cutlery drawer. Furthermore, the dishwasher has a door to close the washing container. When the crockery basket is in an extracted state, the door can not be properly closed because the door collides with the crockery basket being pulled out. The crockery basket must first be moved into the washing compartment. Only then can the door be closed completely and without collision with the dish rack.

Against this background, an object of the present invention is to provide an improved domestic dishwasher.

Accordingly, a household dishwasher with a door and a Spülgutaufnahme is provided. The Spülgutaufnahme is adapted to automatically move in response to a movement of the door.

By the Spülgutaufnahme moves in response to the movement of the door, a user of the household dishwasher does not need to take the Spülgutaufnahme to effect a shift of the Spülgutaufnahme. Thus, by simply pressing the door the Spülgutaufnahme be relocated. This facilitates the use of a domestic dishwasher, since only one handle is necessary to move the door and the Spülgutaufnahme. In addition, such a household dishwasher saves time, since the displacement of the Spülgutaufnahme and the movement of the door can be done simultaneously.

Preferably, the domestic dishwasher comprises a receiving area, also referred to in professional circles as "washing container", which one, two or three Spülgutaufnahmen receives. The door is set up to seal the receiving area watertight. Preferably, the door when opening to a floor on which the household dishwasher is, pivoted out. For example, two or three Spülgutaufnahmen may be adapted to automatically move in response to the movement of the door. Preferably, the Spülgutaufnahme is adapted to be displaced by means of a rail from the receiving area. Such relocation may be, for example, a linear method. The process takes place in particular in a plane that is parallel to the floor on which the household dishwasher is located (ie in the horizontal direction). Alternatively or additionally, for example, the method can take place in a plane which is perpendicular to the floor on which the domestic dishwasher is located (ie in the vertical direction), for example if a lower basket lift is provided. As a further alternative, the method can take place in a combination of horizontal and vertical direction, ie in a path-in particular down-pivoting.

"Depending on a movement" means in the present case that there is a causal relationship between the movement of the door and the method of Spülgutaufnahme. The process of Spülgutaufnahme can be done using an energy storage, a motor, a magnet and / or a kinematic coupling with the door. "Automatic" in the present case means that the process of Spülgutaufnahme takes place without this is actuated neither directly nor indirectly by means of the user's muscular strength.

According to one embodiment, the Spülgutaufnahme to avoid a collision with the door is movable. Thus, the Spülgutaufnahme is set up to avoid a collision with the door. This facilitates the handling of the household dishwasher. Furthermore, shocks between the door and the Spülgutaufnahme be avoided, so that the risk of damage to guide rails or dishes is reduced. In addition, thus a harmonious movement of the door during the closing process can be ensured.

According to one embodiment, the domestic dishwasher has a collection device. The collection device is adapted to the To move Spülgutaufnahme from an extended position to a retracted position. This has the advantage that the Spülgutaufnahme can be moved automatically using the feed device in the receiving area of the household dishwasher. For example, the collection device may be referred to as a return mechanism. The extended position of the Spülgutaufnahme is a position in which a collision with the door is possible. The retracted position of the Spülgutaufnahme is a position at which the Spülgutaufnahme is completely disposed within the receiving area of the household dishwasher, so that no collision with the door is possible. Preferably, the collection device is adapted to move the Spülgutaufnahme only (and not vice versa) from the extended position to the retracted position.

According to one embodiment, the collection device is adapted to move the Spülgutaufnahme from the retracted position in the extended position. This has the advantage that the Spülgutaufnahme by means of the collection device can also be moved out of the receiving area automatically. For example, a retraction of the Spülgutaufnahme is triggered by the opening movement of the door.

For example, spring energy or magnetic energy can be stored during retraction of the Spülgutaufnahme from the receiving area of the household dishwasher. The driving in of the Spülgutaufnahme into the receiving area of the household dishwasher can then be done using the stored energy. This has the advantage that not necessarily additional electrical energy has to be expended for the process of Spülgutaufnahme.

According to one embodiment, the collection device comprises an actuator which is supplied with energy external to the device and which is set up to move the washware receptacle. The actuator may comprise an electromagnet, which causes the method of Spülgutaufnahme using an electromagnetic force. Furthermore, can the actuator as another motor, in particular electric motor, be formed. This has the advantage that the user of the household dishwasher does not have to provide the energy himself.

According to one embodiment, the household dishwasher comprises a first sensor for detecting a position of the Spülgutaufnahme. This has the advantage that the domestic dishwasher can determine automatically whether a risk of collision of Spülgutaufnahme with the door basically exists (because the Spülgutaufnahme is pulled out). For example, a corresponding sensor for each Spülgutaufnahme the household dishwasher are provided.

According to one embodiment, the first sensor comprises a light barrier and / or a proximity sensor. The light barrier is arranged, for example, in an opening region of the receiving area of the household dishwasher. The proximity sensor can be arranged, for example, on a rear wall of the receiving area of the household dishwasher. This can ensure that the detection of the position of the Spülgutaufnahme takes place reliably.

According to one embodiment, the household dishwasher comprises a second sensor for detecting the movement of the door. This has the advantage that the household dishwasher can determine automatically whether the door is moved. It is understood that the second sensor also detects only one position of the door. This can be closed, for example, upon detection of a change in position of the door to a movement of the door. By evaluating the data of the first and second sensors can be concluded that an imminent collision.

According to one embodiment, the second sensor comprises a rotary encoder and / or a tilt angle meter. The rotary encoder can be arranged for example in a door hinge. Furthermore, the inclinometer may be provided in the door. For example, the inclination angle meter detects an opening angle of the door. The rotary encoder detects, for example, a movement, for example, opening angle acceleration and / or opening angle speed of the door. Alternatively or additionally, the rotary encoder can detect, for example, the opening angle of the door.

According to one embodiment, the domestic dishwasher comprises a third sensor which is set up to detect an approach of the door to the washware receptacle.

In this case, for example, a distance between an inner side of the door and an outer side of the Spülgutaufnahme, which faces the inside of the door when closing the door, are detected by the third sensor. A reduction of this distance can be interpreted as approaching the door to the Spülgutaufnahme. In the presence of the third sensor, for example, the first and / or second sensor can be omitted, since by means of the third sensor, a collision detection can be done on the door.

According to one embodiment, the household dishwasher comprises a control device that is configured to control the method of the Spülgutaufnahme. Preferably, the collection device, in particular the actuator and / or an energy storage, are controlled by means of the control device.

According to one embodiment, the control device controls the method of the Spülgutaufnahme depending on the detected by the second sensor movement of the door. For example, the position or movement of the door can serve as an input to the control device, wherein the control device is adapted to detect a change in position of the door and to control the collection device.

According to one embodiment, the control device controls the method of Spülgutaufnahme depending on the detected by the first sensor position of the Spülgutaufnahme. Thus, the detected position of the Spülgutaufnahme serve as a further input variable for the control device to determine whether a risk of collision between the door and the Spülgutaufnahme is imminent.

According to one embodiment, the control device controls the method of Spülgutaufnahme depending on the detected by the third sensor approach of the door to the Spülgutaufnahme. For example, a direct detection of the approach of the door to the Spülgutaufnahme as an input to the control device serve. Based on this input variable, the control device, for example, the collection device, in particular the actuator and / or the energy storage, are controlled.

According to one embodiment, the Spülgutaufnahme is designed as a dish rack or as a cutlery basket. For example, the household dishwasher comprises two baskets and a cutlery basket.

Furthermore, a method for displacing a Spülgutaufnahme a household dishwasher, in particular as described above, is provided. In this case, the Spülgutaufnahme moves in response to a movement of a door of the domestic dishwasher, in particular to avoid a collision with the door, automatically.

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

The Fig. 1 shows a schematic perspective view of a household dishwasher 1 The household dishwasher 1 has a receiving area 2, which is closed by a door 3 in particular waterproof. For this purpose, a sealing device can be provided between the door 3 and the receiving area 2. The receiving area 2, a washing container in the Fig. 1 be shown domestic dishwasher 1. The receiving area 2 is preferably cuboidal. The receiving area 2 and the door 3 can form a rinsing chamber 4 for rinsing dishes. The receiving area 2 can be arranged inside a housing of the household dishwasher 1.

The door 3 is in the Fig. 1 shown in their open position. By pivoting about a provided at a lower end of the door 3 pivot axis 5, the door 3 can be closed or opened. The receiving area 2 has a wall 6 with a bottom 7, a ceiling 7 arranged opposite the floor 7, a door 3 arranged opposite the rear wall 9 and two side walls 10, 11 arranged opposite one another.

The domestic dishwasher 1 further has at least one Spülgutaufnahme 12, 13, 14. In particular, a plurality of Spülgutaufnahmen 12, 13, 14 may be provided, which may include a lower basket 12, a top basket 13 and / or a cutlery drawer 14. The plurality of Spülgutaufnahmen 12, 13, 14 are preferably arranged one above the other in the receiving area 2. Each Spülgutaufnahme 12, 13, 14 is either in the receiving area 2 zoom in or out of this herausverlagerbar. In particular, each Spülgutaufnahme 12, 13, 14 in one Insertion direction E (arrow) hineinschiebbar in the receiving area 2 and opposite to the insertion direction E (arrow) in an extension direction A (arrow) from the receiving area 2 pulled out.

The Fig. 2 shows a second embodiment of the domestic dishwasher 1. In this case, the upper basket 13 is adapted to automatically move in response to a movement of the door 3. The upper basket 13 has an extended position in which the upper basket 13 protrudes from the washing compartment 4. Consequently, the upper basket 13 could collide with the door 3 when it is closed. To avoid this, the upper basket 13 is adapted to avoid a collision with the door 3. For this purpose, the domestic dishwasher 1 comprises a collection device 15. This is configured to move the upper basket 13 from the extended position into a retracted position (as in FIG Fig. 4 shown) to proceed. The collection device 15 is arranged on the door 3. An automatic entry of the upper basket 13 in the receiving area 2 can be done with the aid of energy (for example, spring energy, magnetic energy), which was stored during the extension of the upper basket 13 from the receiving area 2.

Furthermore, the household dishwasher 1 comprises a sensor 16 (also referred to herein as a third sensor), which is adapted to detect an approach of the door 3 to the upper basket 13. The sensor 16 is arranged on an inner side 18 of the door, wherein the inner side 18 of the door 3 faces the rinsing chamber 4 in the closed state of the door 3. A to be detected by the sensor 16 to be detected 17 is disposed on an outer side 19 of the upper basket 13 and connected thereto or a part thereof, wherein the outer side 19 of the upper basket 13 in the closed state of the door 3 of the inner side 18 of the door 3 faces. The sensor 16 is firmly connected to the door 3. Alternatively, the sensor 16 could be arranged on the outer side 19 of the upper basket 13 and the measuring object 17 on the inner side 18 of the door 3. In any case, the sensor 16 and the measuring object 17 are arranged such that they approach when closing the door 3. If a corresponding approach, in which a collision between the door 3 and the upper basket 13 is possible, is detected or detected, then the upper basket 13 moves into the retracted position by means of the collection device 15. The domestic dishwasher 1 comprises a control device 22 which is adapted to control the process of the upper basket 13. For this, the control device 22, for example, with the collection device 15 (dashed in FIG Fig. 2 shown) and the sensor 16 signal-coupled. The door 3 does not touch the upper basket 13.

The collection device 15 comprises a spring element serving as energy storage. The collection device 15 is thus adapted to move the upper basket 13 by means of spring force. For this purpose, the collection device 15 with the rear wall 9 (or one of the two side walls 10, 11) and, for example, an inner side 21 of the upper basket 13 may be connected, wherein the inner side 21 of the upper basket 13 of the rear wall 9 faces. The collection device 15 is biased in the extended position of the upper basket 13 in the direction of insertion E (arrow). Furthermore, the upper basket 13 may be locked in this extended position. The collection device 15 can be set up to release a lock during a closing movement of the door 3, so that the upper basket 13 is pulled by the spring element in the insertion direction E (arrow). A collision of the door 3 with the upper basket 13 is therefore prevented.

The Fig. 3 shows the household dishwasher 1 Fig. 2 , wherein the door 3 has a smaller opening angle α than in Fig. 2 shown. As a result, the closing movement of the door 3 should be indicated. It can be seen that despite a movement of the door 3 in the direction of a closed position of the same, an air gap or distance S between the sensor 16 and the measuring object 17 is maintained. The upper basket 13 moves from the extended position (as in Fig. 2 shown) in the retracted position (as in Fig. 4 shown), without the door 3 touches the upper basket 13 and without a user of the domestic dishwasher 1 touches the upper basket 3.

The Fig. 4 shows the household dishwasher 1 Fig. 2 with the upper basket 13 in the retracted position.

The Fig. 5 shows a third embodiment of the household dishwasher 1. Unlike Fig. 2 show the Fig. 5 the domestic dishwasher 1 with a sensor 23 (also referred to herein as the first sensor) for detecting a position of the upper basket 13 by means of a corresponding object to be measured 26 on the upper basket 13. The sensor 23 is designed as a proximity sensor. This is arranged on the inner side 21 of the upper basket 13 and / or on the rear wall 9 and detects, for example the distance between the inner side 21 of the upper basket 13 and the rear wall 9. This can reliably a deployed position of the upper basket 13 can be detected. Furthermore, the household dishwasher 1 comprises a sensor 24 (also referred to herein as a second sensor) for detecting the movement of the door 3. The sensor 24 is designed as a rotary encoder and is arranged in a hinge of the door 3. The upper basket 13 is moved by means of an actuator 25. The control device 22 controls the process of the upper basket 13 as a function of the movement of the door 3 detected by the sensor 24. For this purpose, the control device 22 is signal-coupled to the sensor 24 (in FIG Fig. 5 indicated by dashed lines). Furthermore, the control device 22 controls the process of the upper basket 13 as a function of the position of the upper basket 13 detected by the sensor 23. For this purpose, the control device 22 is signal-coupled to the sensor 23 (in FIG Fig. 5 indicated by dashed lines). The actuator 25 is also signal-technically coupled to the control device 22 (in FIG Fig. 5 indicated by dashed lines). Receives the controller 22 from the sensor 24, the information that the door 3 is closed, then can be determined by checking whether the upper basket 13 has an extended position, whether a collision situation is imminent, so that in the positive case, the actuator 25 is driven to spend the upper basket 13 in the retracted position. Accordingly, a sensor 23 and an actuator 25 are provided for the lower basket 12, which are signal-technically coupled to the control device 22 (in Fig. 5 indicated by dashed lines). The actuator 25 includes, for example, an electromagnet. Furthermore, the actuator 25 may be formed as any motor, in particular electric motor.

If the opening angle α falls below a threshold value, wherein at the same time the upper basket 13 has an extended position, a return mechanism is automatically activated and the upper basket 13 is withdrawn into the receiving area 2 before a collision occurs between the door 3 and the upper basket 13. Furthermore, the collection device 15 is adapted to move the upper basket 13 from the retracted position to the extended position. In this case, upon detection of an opening movement of the door 3, the upper basket 13 can be automatically moved out of the receiving area 2 in order to facilitate loading of the upper basket 13.

The Fig. 6 shows a fourth embodiment of the household dishwasher 1. Unlike Fig. 5 the sensor 24 is designed as a tilt angle. Of the Tilt angle 24 is disposed within the door 3. Furthermore, the sensor 23 comprises a light barrier. The light barrier 23 is arranged within a plane B arranged parallel to the rear wall 9. In this case, the distance between the plane B and the rear wall 9 corresponds approximately to a length L of the upper basket 13. Thus, over the entire length L of the upper basket 13, an extended position of the upper basket 13 can be reliably detected by means of the light barrier 23.

It is understood that all in Fig. 1 to 3 also shown in features Fig. 5 or 6 can be trained and vice versa.

Although the present invention has been described with reference to embodiments, it is variously modifiable.
