Definitions
- the invention relates to maintenance planning for a domestic appliance.
- the invention relates to the scheduling of predictive maintenance of the domestic appliance.
- a household appliance requires maintenance from time to time which the appliance cannot carry out independently or as part of a normal operation. For example, a coffee machine may require descaling, or a dishwasher may require cleaning. Modern household appliances can determine when maintenance is to be carried out and alert a user to the need for maintenance by means of a signal. If the user does not comply with the request, maintenance can be postponed. If the maintenance has been carried out, the message can be turned off again. Usually, the message is also switched off again if the maintenance has not been carried out for a certain period of time.
- a user can only be insufficiently notified of upcoming maintenance. For example, it may not be clear to the user what consequences he must expect if he does not carry out maintenance or only after some time. A self-deactivating message can easily be forgotten so that maintenance may never take place.
- US 2014 0 025 219 A1 proposes to prevent the operation of a domestic appliance during the Sabbath in advance.
- One object on which the present invention is based is to provide an improved technique for planning upcoming maintenance of a domestic appliance.
- the invention solves this problem by means of the subjects of the independent claims. Un subclaims show preferred embodiments.
- a method comprises steps of determining maintenance to be carried out on a domestic appliance; the recording of appointments that are entered in a calendar assigned to the household appliance; determining a date for maintenance depending on the determined dates; and entering the appointment in the calendar.
- the appointment for servicing the domestic appliance can be set at a time when no other appointment has to be made. Maintenance can thus be better coordinated with other activities that can also be planned using the calendar. For a time interval between the maintenance appointment and another appointment, an interval between places of fulfillment of the appointments can be taken into account.
- the household appliance is usually assigned to a predetermined household.
- the maintenance date also referred to herein as the maintenance date, can be determined to be close to another date that is set in the area of the domestic appliance or in the household.
- the invention can be used both with a conventional calendar and with a task list (“To Do”).
- the task list can be integrated into the calendar, whereby a formal distinction can be made between appointments and tasks or not.
- the task list contains tasks as entries, each of which usually has a fulfillment time. When a task has been completed, it can be marked as completed. There can be dependencies between tasks so that, for example, a first task only becomes active or editable after a second task has been marked as completed, or so that a third task can only be marked as completed when a fourth is marked as completed.
- a task can be assigned to one or more people or groups. In this sense, a task in a task list is to be understood as an embodiment of an appointment in a calendar.
- the maintenance date can also be entered as a maintenance task.
- the home appliance can be controlled depending on the date entered. In particular, it can be ensured that an operation or use of the domestic appliance is completed when the maintenance date is reached.
- the use is preferably already concluded a predetermined time before the maintenance date occurs, so that the household appliance can, for example, cool down, dry or clear out before maintenance.
- a dishwasher can, for example, be controlled to end a cleaning program approx. 30 minutes before the maintenance date, so that it can be opened and dishes can be removed from it.
- the operation of the domestic appliance can be coordinated with the maintenance. If, for example, a washing machine is to be descaled as part of maintenance, it can until the actual decalcification can be controlled to extend a heating process in order to compensate as much as possible for the thermal insulation effect of a layer of lime on a heating rod.
- the need for maintenance is usually determined by the household appliance on a time and / or event basis.
- an urgency of the maintenance can be determined.
- the urgency can be specified on a freely selectable scale.
- a date can be determined by which the maintenance should be completed, whereby the urgency can be increased further and further in the course of time up to this date. If the deadline is exceeded, the specific urgency can be further increased.
- the urgency preferably does not exceed a predetermined maximum.
- a point in time is determined at which damage is likely to occur on the domestic appliance if the maintenance has not been carried out by then, it being possible to determine the urgency with regard to this point in time.
- the damage can be irreversible or reversible through maintenance. Several times can also be determined at which there are predetermined risks of damage to the domestic appliance, and the urgency can be determined as a function of a time interval up to at least one of these times.
- the maintenance date can be determined depending on the urgency of the maintenance to be carried out. If, for example, in a period in which the urgency is below a predetermined value, no date can be determined that does not collide with an already existing date, then in a second period that follows the first period and in which the Urgency is above the predetermined value, a maintenance appointment will be searched more aggressively. For example, the specified maintenance date can collide with an existing date. An attempt can be made to minimize the overlap of the appointments as far as possible and / or to allow an overlap only with an appointment that is as little urgent as possible, less important or less long.
- an attribute of the appointment is set depending on the urgency of the maintenance.
- the urgency can be signaled to help meet the deadline.
- the attribute can include, for example, a keyword such as COMING SOON, IMPORTANT, IMMEDIATELY or DANGER in the title or description of the appointment.
- a predetermined range of keywords can be used den, to express the urgencies assigned to each.
- the urgency can also be indicated numerically, for example on a scale from 1 to 10.
- the appointment can be given a predetermined color, for example on a gradient from blue to red with increasing urgency. If the calendar supports a priority, the urgency can also be mapped to the priority.
- the maintenance date can be postponed if a conflicting date is determined after the maintenance date has been entered.
- the automatic postponement of the maintenance date makes it easier to plan the other dates. A user can be less disturbed or better supported in his scheduling behavior.
- a latest possible date for the maintenance is determined, a signal being output if the date is postponed beyond the latest possible date. This can prevent the maintenance date from being postponed until damage is to be feared due to the unexpected operation of the domestic appliance, or even until the domestic appliance can no longer be operated.
- the signal can be directed to a person assigned to the calendar and can take the form of a message such as an e-mail or an SMS, for example.
- the maintenance date can be prevented from being postponed beyond a predetermined point in time. An authorization model of the calendar can be used to prevent this.
- a common date can be set for the multiple maintenance work.
- the maintenance work can be planned one after the other or overlapping in time. It can be taken into account which activity is required by a user performing the maintenance. For example, decalcifying a kettle by a user can essentially include filling in a decalcifying agent, starting a decalcifying run and decalcifying require removal of the descaler after it has been completed, so that the user can also perform maintenance on another household appliance during the descaling run.
- the calendar is assigned to a user who is assigned to the household appliance, it being possible for the user to be assigned to the household appliance.
- the maintenance date can be determined specifically for this user.
- the maintenance date can be determined by means of an adapting or self-learning algorithm, so that the maintenance date can be determined in an improved manner based on a preference or requirement of the user.
- the algorithm can take into account, for example, how much time has elapsed in the past between entering a maintenance date in the calendar and performing the maintenance, or how often or how far the maintenance date was postponed by the user.
- a maintenance date can be entered for that user in whose calendar the most suitable, in particular the earliest, free time could be found.
- a maintenance date can be entered in an assigned calendar for each user. If the maintenance date has been kept, superfluous maintenance dates can be deleted again. Other procedures are also possible, for example entering the maintenance date in a group calendar for the people.
- the appointment may include an indication of a procedure, material or tool required for maintenance.
- the notice can be in the form of specific information or a reference to a document.
- the document can be kept available on any server or service, optionally in a cloud.
