Description

System with a dishwasher and method for operating a dishwasher

The present invention relates to a system with a dishwasher, such as a household dishwasher, and a method for operating a dishwasher.

A household dishwasher sometimes includes a wash container, which can be closed by a door, with a number of wash ware receptacles for receiving wash ware and a control device for carrying out a wash program from a plurality of wash programs for washing wash ware.

The document DE 102017218493 A1 shows a household dishwasher with a housing, a door pivotably connected to the housing, a cable connected to the door, a roller in contact with the cable and a motor which is set up to move the roller to drive the rope in such a way that a pivoting movement of the door is effected.

The document DE 102017213699 A1 describes a household dishwasher, which comprises a washing container, a washware receptacle for receiving washware and a lifting device which is set up to move the washware receptacle in a first displacement plane from a starting position located inside the washing container to an outside of the washing container arranged end state or vice versa, and which is set up to raise the washware receptacle in a second displacement plane different from the first displacement plane from an initial position to an end position and lower it from the end position to the initial position. The lifting device has a linear drive and a coupling unit for coupling the washware receptacle to the linear drive, the coupling unit from a first coupling state in which the washware receptacle is coupled to the linear drive so that it is only in the first displacement plane with the aid of the linear drive can be displaced into a second coupling state in which the washware receptacle is coupled to the linear drive so that it can be moved with the aid of the line arantriebs is only displaceable in the second displacement plane, and vice versa spend bar.

Against this background, one object of the present invention is to further improve the operation of a dishwasher.

According to a first aspect, a system is proposed with a dishwasher, in particular a domestic dishwasher, having a wash compartment that can be closed by a door with a number of wash ware receptacles for receiving wash ware, a control device for performing a wash program from a plurality of wash programs for washing wash ware , a pivoting device for automatically pivoting the door and a movement device for automatically moving at least one of the washware receptacles, with a determination unit for determining a loading request of a user of a number of loading requests for loading and unloading the washing container, with a determination unit for determining a movement sequence comprising at least one pivoting of the door and at least one movement of one of the washware receptacles based on the determined loading request, and with a control unit which is set up to pivot the device and to control the movement device for executing the particular movement sequence.

The guided loading and unloading process leads to optimal loading and therefore optimal washing results, in particular comprehensive cleaning, drying and care of wash ware, tailored to the individual load and user situation.

By using the determination unit, the determination unit and the control unit, the pivoting device for opening and closing the door and the movement device for extending and retracting the washware receptacles can advantageously be controlled in such a way that the dishwasher can be loaded and unloaded is improved. On the one hand, the loading and unloading of the dishwasher is improved since the loading can be optimized with regard to the washing result. If, for example, the user approaches the dishwasher with a dirty pot, the door can be opened automatically and the lower washware receptacle (e.g. the lower basket) can be raised to enable the user to remove the dirty To arrange pot in this. The lower washware receptacle can then be retracted into the washing compartment, the door can be locked and the dirty pot arranged in the lower washware receptacle can be washed optimally.

On the other hand, the loading and unloading of the dishwasher is improved to the effect that both loading and unloading can be carried out more ergonomically for the user. Thanks to the automatic increase in the lower load capacity, very back-friendly effects come into play.

The automatic opening and closing of the door and the automatic extension and retraction of the washware receptacles also require fewer manual interactions by the user with the dishwasher, and the ease of use is made easier by avoiding manual opening and closing. In particular, the user no longer has to open the door with dirty hands or move the items to be washed.

The specific sequence of movements can also be referred to as an automated sequence of movements. The automated sequence of movements includes at least one pivoting of the door (opening and / or closing the door) and at least one movement of one of the items to be washed, e.g. B. the upper basket and / or the lower basket. In particular, the automated sequence of movements includes door opening and door closing in combination with an automated entry and exit for the lower basket and upper basket and an automated raising of the lower basket to the level of the upper basket.

For example, the number of loading requests by the user for loading and unloading the dishwasher can include: loading the lower basket, loading the upper basket, loading the lower basket and the upper basket, unloading the lower basket, unloading the upper basket, unloading the lower basket and the upper basket.

The control device can be implemented in terms of hardware and / or also in terms of software. The control device is integrated in particular in the dishwasher. Alternatively, the control device can also be arranged outside the dishwasher. In the case of a hardware implementation, the control device can be designed, for example, as a computer or as a microprocessor being. In the case of a software implementation, the control device can be designed as a computer program product, as a function, as a routine, as part of a program code or as an executable object.

The control device is sometimes set up to carry out a washing program from a plurality of washing programs for washing the items to be washed. A washing program includes, for example, various partial program steps, such as pre-washing, cleaning, rinsing and / or drying. Different washing programs differ, for example, in a sequence and / or type of partial program steps, as well as in different operating parameters, such as a duration and / or washing liquor temperature of one or more partial program steps.

For washing with the domestic dishwasher, items to be washed are arranged in the washing chamber, in particular on one or more items to be washed.

According to a further embodiment, the system comprises a transmission unit which is set up to transmit the learned movement sequences to a further dishwasher via a network. The learned movement sequences can also be transmitted to a server, in particular of the device manufacturer, by means of the transmission unit. The device manufacturer's server can, in particular, perform a cluster analysis of the usage behavior of different users and offer optimized movement sequences for a large number of users and their dishwashers.

According to a further embodiment, the determination unit has: a proximity sensor for detecting an approach of a user to the dishwasher indicative of a loading request, a voice input unit for detecting a voice input by the user indicative of a loading request, a gesture input unit for detecting a a loading request indicative gesture input of the user, and / or a haptic input unit for detecting a loading request indicative haptic user input of the user.

According to a further embodiment, the system comprises a device which is external to the dishwasher and which at least integrates the determination unit.

According to a further embodiment, the determination unit is designed as part of an app that can be installed on the external device.

The external device is in particular a mobile device, which can also be referred to as a mobile terminal device. The mobile device is, for example, a smartphone, a tablet or a tablet computer.

According to a further preferred embodiment, a sensor device for outputting a sensor signal indicative of the door is arranged on the door. In this case, the control device is preferably set up to detect the sensor signal and, as a function of the detected sensor signal, to recognize an abnormal state of a number of predetermined abnormal states of the door and to carry out a predetermined action as a function of the detected abnormal state.

Details on this are described in the international patent application WO 2019/105832 A1 (PCT / EP2018 / 082164), the content of which is hereby fully incorporated by reference.

According to a second aspect, a computer program product for a computer for operating a dishwasher is proposed, the computer program product comprising commands which, when the computer program product is executed, cause the computer to carry out the following steps:

Loading of learned movement sequences from a memory unit, which is preferably set up to store certain movement sequences when operating another dishwasher as learned movement sequences by means of machine learning, and Execution of at least a part of the loaded movement sequences for operating the dishwasher.

According to a third aspect, a method for operating a dishwasher, in particular a domestic dishwasher, having a washing compartment that can be closed by a door with a number of washware receptacles for receiving washware, a control device for performing a wash program from a plurality of wash programs for washing washware , a pivoting device for automatically pivoting the door and a movement device for automatically moving at least one of the washware receptacles. The procedure consists of the following steps:

Determining a loading request of a user of a number of loading requests for loading and unloading the washing compartment,

Determining a sequence of movements comprising at least one pivoting of the door and at least one movement of one of the washware receptacles based on the determined loading request, and

Controlling the pivoting device and the moving device for executing the specific sequence of movements.

The embodiments and features described for the proposed system apply accordingly to the proposed method.

According to a fourth aspect, a computer program product is proposed which causes the method as explained above to be carried out on a program-controlled device.

A computer program product, such as a computer program means, for example, can be provided or delivered as a storage medium such as memory card, USB stick, CD-ROM, DVD, or in the form of a downloadable file from a server in a network. This can be done, for example, in a wireless communication network by transmitting a corresponding file with the computer program product or the computer program means. The following six examples can illustrate the functionality of the present system:

Example 1:

A proximity sensor in the system detects that a user is moving towards the dishwasher. Plates in the hands of the user are recognized by means of a photo from a camera of the system, for example integrated in the outer skin of the dishwasher. As a result, the door of the dishwasher opens completely, the lower basket moves out and is raised to the maximum height of the upper basket according to the height of the user, in order to enable the user to put them away ergonomically. After loading, when the user moves away from the dishwasher, the lower basket is lowered and retracted again and the door closes automatically.

Example 2:

A proximity sensor in the system detects that a user is moving towards the dishwasher. By means of a photo from a camera of the system, for example integrated in the outer skin of the dishwasher, plates and glasses are recognized in the hands of the user. The dishwasher door opens completely, the lower basket extends completely and the upper basket extends halfway. In this way, the user can easily put both types of crockery in the right baskets. After a clearing, when the user moves away from the dishwasher, the baskets are retracted again and the door closes automatically.

Another embodiment of the above-described scenario according to example 2 is as follows: the dishwasher detects by means of a proximity sensor that a user is moving towards the dishwasher. Plates and glasses in the hands of the user are recognized by means of a photo taken by a camera of the system. The dishwasher door opens completely and the upper and lower racks slide out. In this way, the user can first put away the glasses on the plates. After a short time, the upper basket is retracted and the lower basket is raised to the height of the upper basket, depending on the user's body size, so that the user can easily and ergonomically place the rest of the plates. After the clearing, When the user moves away from the dishwasher, the lower basket is lowered and retracted again and the door closes automatically.

Example 3:

The user has a habit of having a cup of coffee every morning before leaving the house. The present system recognizes this pattern very quickly on working days in a learning phase, in particular by means of machine learning. For this purpose, analysis data with regard to door opening, time and dishes, in this case an empty coffee cup, are evaluated. In particular, device data, wash ware data and evaluated photos can be used for this purpose.

Therefore, after a short time, the user can enjoy the fact that the dishwasher recognizes in the morning when he approaches the dishwasher with an empty coffee cup. The dishwasher opens the door 45 ° and extends the upper basket halfway so that the user can immediately put the cup in the correct basket, in this case the upper basket. After loading, when the user moves away from the dishwasher again, the upper basket is retracted and the door closes automatically.

The above-mentioned learning can preferably also be actively supported by the user. For example, the user can tell the dishwasher a rule in a corresponding app, such as. For example: "If I approach the dishwasher with a cup between 7:00 am and 7:15 am on weekdays, open the door to 45 ° and pull out the upper basket a little so that I can put the coffee cup away."

This sequence of movements can, for example, also be triggered by a gesture control.

Example 4:

The automated movement sequence can be adapted by analyzing usage data with a focus on the daily routine. The following example relates to the loading process for the dishwasher after dinner on weekdays. The following data can be analyzed here. a) Time of door opening in relation to the course of the day (frequency of opening between 4.30 p.m. and 7 p.m.); b) door opening time (opening time longer than 20 s); c) number of basket movements of the upper basket; d) Number of basket movements of the lower basket; e) dwell times of the basket positions of the upper basket (basket remains extended for longer than 20 s); f) Duration of the basket position of the lower basket (basket remains extended for longer than 20 s); g) the number of times the lower basket is raised; h) Time of the program start (program start only after loading, ie after 7:30 p.m.).

By analyzing the above data, the automatic door opening time and the dwell time of the upper basket and lower basket are adapted to the extended position.

By analyzing the usage data, it becomes clear that the dishwasher is loaded on working days after dinner, ie between 4:30 p.m. and 7:00 p.m. This can be determined by the regularity and characteristics of the parameters a) to h) given above. If the dishwasher now recognizes through the proximity sensor that the user is approaching him with dishes in hand, the automatic sequence of movements is triggered. In this scenario, the lower basket is not raised. Since items of wash ware are loaded for both racks, the lower basket moves out by 100% and the upper basket by 45%, so that all wash ware items relevant for this scenario can be loaded at the same time. Due to the knowledge from the analysis of the usage data, when the user is removed from the dishwasher, the baskets are not automatically retracted and the door is not closed, since the loading in this scenario can extend over several loading steps and / or over a longer period of time . Thus, the loading process is not completed until the user actively terminates it or when a predetermined number of loading steps occurs or when a certain threshold value occurs for the period of time. Completed means in In this context, in particular, the complete retraction of the upper basket and lower basket as well as the subsequent door closure. By adapting the rules to this user behavior, the loading and unloading process can be individualized.

Example 5:

In this example, the analysis of the usage data focuses on the following parameters a) to g): a) Number of basket movements of the upper basket; b) Number of basket movements of the lower basket; c) dwell time at the respective basket position of the upper basket; d) dwell time at the respective basket position of the lower basket; e) the number of times the lower basket is raised; f) washing programs used; g) Start times of the washing programs.

With the help of a model, for example, by using parameters a) to g), a forecast of the filling quantity of the lower basket and the upper basket in percent can be made. For example, let the respective load amount calculated by the model be:

Capacity of the upper basket: 95%

Capacity of the upper basket: 50%

Is now by a sensor signal, z. B. by voice control, triggered by the proximity sensor, the automated sequence of movements, the upper basket is preferably extended, as this has a higher probability of actually being able to pick up the items to be cleaned. The lower basket is not extended automatically, but can be activated at any time by the active operation of the user, e.g. B. can be controlled by voice input or by a button module.

Example 6:

The learned movement sequences of a dishwasher make it possible to transfer these learned movement sequences to the new device when purchasing a new device. Here it is also possible to use learned movement sequences of many individual devices to transfer these learned movement sequences to the purchased new device. A cluster analysis of the usage behavior of an individual device can also be used to suggest a quick solution to the individual device by analyzing the movement sequences of all devices. With regard to this example 6, reference can be made to the above third aspect.

Further possible implementations of the invention also include not explicitly mentioned combinations of features or embodiments described above or below with regard to the exemplary embodiments. The person skilled in the art will also add individual aspects as improvements or additions to the respective basic form of the invention.

Further advantageous refinements and aspects of the invention are the subject matter of the subclaims and of the exemplary embodiments of the invention described below. The invention is explained in more detail below on the basis of preferred embodiments with reference to the attached figures.

1 shows a schematic perspective view of an exemplary embodiment of a system with a domestic dishwasher;

Fig. 2 shows a schematic view of a further embodiment of a system with a domestic dishwasher and an external device; and

Fig. 3 shows a schematic block diagram of an embodiment of a method for operating a domestic dishwasher.

In the figures, elements that are the same or have the same function have been provided with the same reference symbols, unless otherwise stated.

Fig. 1 shows a schematic perspective view of an embodiment of a system with a domestic dishwasher 1. The domestic dishwasher 1 comprises a washing container 2, which can be closed by a door 3, especially water-tight. For this purpose, between the door 3 and the washing container 2 a sealing device can be provided (not shown). The washing container 2 is preferably cuboid. The washing container 2 can be arranged in a housing of the domestic dishwasher 1. The washing compartment 2 and the door 3 can form a washing chamber 4 for washing items to be washed.

The door 3 is shown in FIG. 1 in its 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. For this purpose, a pivoting device for automatically pivoting the door 3 is preferably used. A pivoting device is shown, for example, in DE 102017218493 A1.

With the aid of the door 3, a loading opening 6 of the washing compartment 2 can be closed or opened. The washing compartment 2 has a floor 7, a ceiling 8 arranged opposite the floor 7, a rear wall 9 arranged opposite the closed door 3 and two side walls 10, 11 arranged opposite one another. The floor 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 bottom 7 can be made from a plastic material, for example, se.

The domestic dishwasher 1 also has at least one washware receptacle 12, 13, 14. Preferably, several, for example three, washware receptacles 12,

13, 14 can be provided, wherein the washware receptacle 12 can be a lower washware receptacle or a lower basket, the washware receptacle 13 can be an upper washware receptacle or an upper basket and the washware receptacle 14 can be a cutlery drawer. As FIG. 1 further shows, the items to be washed 12, 13, 14 are arranged one above the other in the washing compartment 2. Each washware receptacle 12, 13, 14 can optionally be moved into or out of the washing container 2. In particular, each washware receptacle 12, 13, 14 can be pushed into the washing container 2 in an insertion direction E and can be pulled out of the washing container 2 in a pull-out direction A counter to the insertion direction E.

In particular, the domestic dishwasher 1 comprises a movement device for automatically moving at least one of the washware receptacles 12, 13, 14. For example, the movement device comprises an extension device which is designed to extend the upper basket 13 from an initial position to an end position and / or to move from the end position to the starting position. It is also possible that the extension device only moves the upper basket 13 from the starting position to an intermediate position located between the starting position and the end position in order to enable the user to place items in the upper basket 13 and then the upper basket 13 again from the intermediate position to retract into the starting position.

As an alternative or in addition, the movement device can also have a lifting device. The lifting device is designed to raise the lower basket 12 from an initial position to an end position in which the user can conveniently place or remove items to be washed in the raised lower basket 12, and / or lower it from the end position to the initial position.

An optical sensor 110 designed as a camera is arranged on the ceiling 8 in such a way that it is set up to record image data of the washing compartment 2 and in particular of the items to be washed in the washing chamber 4. The dashed lines below the camera 110 indicate a detection range of the camera 110. It should be noted that the detection area is not limited to the washing chamber 4.

The domestic dishwasher 1 also has a control device 100, a determination unit 120, a determination unit 130, a control unit 140 and a voice input unit 150, which are arranged on the door 3. The control unit 140 is implemented as part of the control device 100.

The control device 100 is set up to execute a washing program from a plurality of washing programs for washing items to be washed in the washing compartment 2.

The determination unit 120 is set up to determine a loading request by the user from a number of loading requests for loading and unloading the washing compartment 2.

For example, the number of loading requests by the user includes the following: a) loading the lower basket 12, b) loading the upper basket 13, c) loading the lower basket 12 and the upper basket 13, d) Unloading the lower basket 12, e) Unloading the upper basket 13, f) Unloading the lower basket 12 and the upper basket 13.

For example, from these different loading requests, the determination unit 120 determines a loading request by the user, for example from a corresponding voice input.

For example, the determination unit 120 can have various sensors and / or input units. For example, the detection unit 112 has a proximity sensor for detecting an approach of the user to the household dishwasher 1, which is indicative of a charging request . If the user approaches the domestic dishwasher 1, the proximity sensor can detect this and interpret the detected approach as a loading request for loading or unloading the domestic dishwasher 1.

As an alternative or in addition, the determination unit 120 can also have a voice input unit 150 (integrated or additional), a gesture input unit (not shown) and / or a haptic input unit (not shown).

The voice input unit 150 is set up, for example, to capture a voice input by the user that is indicative of a loading request. If, for example, the user says "Please extend the upper basket", the determination unit 120 can interpret this as a loading request and pass the determined loading request on to the determining unit 130 accordingly.

Alternatively or additionally, the determination unit 120 can also be a gesture input unit for recording a gesture input by the user indicative of a loading request and / or a haptic input unit, such as a physical key or a key on a touch-sensitive screen, for recording a include haptic user input of the user indicative of a loading request. Based on the user's loading request determined by the determination unit 120, the determination unit 130 is set up to determine a movement sequence comprising at least one pivoting of the door 3 and at least one movement of one of the washware receptacles 12, 13, 14. If, as in the above example, the user says "Please extend the upper basket", then the sequence of movements determined by the determining unit 130 includes pivoting the door 3 such that the door 3 is fully opened and extending the upper basket 13 by means of the extension device. Based on this specific movement sequence, the control unit 140 will then control the pivoting device and the movement device in such a way that the specific movement sequence is actually carried out, ie in this example the door 3 is opened and the upper basket 13 is actually extended by the extension device, so that the user has the option of putting his items in the extended upper basket 3.
