Description

Method and system for operating a system comprising a vacuum cleaner and a base station

Technical Field

The invention relates to a method for operating a system comprising a vacuum cleaner and a base station. The invention also relates to a system comprising at least one vacuum cleaner and at least one base station. The vacuum cleaner comprises at least one blower and at least one separating device for the suction. The base station comprises at least one base station (Basis) separating device for the aspirant. The vacuum cleaner may be connected to a base station. During a suction operation of the cleaner, a separating apparatus for receiving suction is fluidly connected to the blower. For regeneration purposes, the cleaner is fluidly connected to the base station for conveying suction from the separation apparatus to the base station separation apparatus.

Background

Vacuum cleaners, base stations and systems and methods for operating, in particular emptying or cleaning, the separating apparatus of a vacuum cleaner are known in the prior art in various configurations. The vacuum cleaner is, for example, a hand-held or self-propelled battery vacuum cleaner, in particular a vacuum cleaning robot. The cleaner includes separating apparatus for cleaning at least one suction airstream of suction material. The vacuum cleaner is connected to a base station for emptying or cleaning a separating apparatus, such as a suction chamber of the separating apparatus. In the process, a suitable flow path is established at least between the separating apparatus of the cleaner and the base separating apparatus of the base station, and the suction is conveyed from the separating apparatus to the base separating apparatus.

The methods known in the prior art for operating a system comprising a vacuum cleaner and a base station and the known systems comprising a vacuum cleaner and a base station have the following disadvantages: the filling level of the separation device, the filling level of the base station separation device or the flow path state data, i.e. the flow state of one flow path, can only be determined by a plurality of sensors (emitteln).

Disclosure of Invention

The invention is therefore based on the following object: a method for operating a system comprising a vacuum cleaner and a base station and a system comprising a vacuum cleaner and a base station are proposed, in which the filling degree of the separating apparatus can be reliably determined while minimizing the expenditure on sensors.

The above object is achieved by a method according to claim 1, i.e. in a suitable type of method by the following method steps:

-acquiring (erfassen) operating data of the vacuum cleaner and/or operating data of the base station at least during a regeneration operation,

-transmitting operating data of the dust collector to the base station and/or transmitting operating data of the base station to the dust collector, and

-determining at least one filling state of the separating apparatus and/or at least one filling state of the base station separating apparatus and/or at least flow path state data of at least one flow path by using operating data of the vacuum cleaner and/or operating data of the base station.

The vacuum cleaner is fluidly and/or data communicatively connected to, or connected to, a base station prior to acquiring operational data. In the regeneration operating range, the suction is conveyed from the separating device of the vacuum cleaner to the base station separating device. The conveying is carried out either by a base station blower of the base station, in particular by sucking the separating device of the vacuum cleaner away by the base station blower, and/or by a blower of the vacuum cleaner, in particular by generating a regeneration air flow by the blower of the vacuum cleaner, which air flow conveys the suction from the separating device to the base station separating device. To this end, the flow paths required in the cleaner and base station will be created or released. The separating apparatus of the cleaner is cleaned by a regeneration operation of the suction, so that it can be used again for another suction operation of the cleaner.

In order to be able to determine the filling state of the separating device and/or of the base station separating device and, if necessary, to detect a narrowing of the cross section of the flow path, for example due to contamination with aspirant, operating data of the vacuum cleaner and/or of the base station are acquired at least during the regeneration operation.

The vacuum cleaner preferably comprises at least one first data processing device. The base station preferably comprises at least one second data processing device. A data processing apparatus preferably comprises at least one processor and at least one memory. In particular, those processes which require data processing on the vacuum cleaner or the base station take place in any case with the participation of the respective data processing device. The operating data of the vacuum cleaner are preferably acquired by the first data processing device. The operating data of the base station are preferably acquired by the second data processing device.

The operating data are data generated by the individual components, in particular during the regeneration operation of the vacuum cleaner and the base station, and preferably data which can be processed by the data processing device. For example, the operating data comprise engine operating parameters of at least one blower engine, engine operating parameters of at least one base station blower engine, in particular the rotational speed and the power consumption, the power level of the blower engine and/or the base station blower engine, and also measured values from sensors present in the vacuum cleaner and/or the base station, for example pressure sensors or differential pressure sensors and/or volume flow. The operating data of the cleaner or base station comprises, for example, all or at least some of the above data.

Depending on whether the operating data are further processed in the base station or the vacuum cleaner, in particular using the operating data for the determination, at least the operating data of the vacuum cleaner acquired during the regeneration operation are transmitted completely or partially to the base station and/or the operating data of the base station are transmitted completely or partially to the vacuum cleaner.

The transfer is performed during and/or after the regeneration operation is completed. Preferably, only the operating data of the one device, the vacuum cleaner or the base station, is transmitted to the respective other device for making the determination. The determination is made, for example, with the base station, in particular with the second data processing device of the base station.

In the determination of the filling state of the separation device and/or the filling state of the base station separation device and/or the flow path state data of the at least one flow path, the collected operating data is evaluated, compared with reference values and/or used in an algorithm, for example.

The determined filling state comprises, for example, a degree of filling of the aspirate and/or the aspirate chamber for the filter and/or a degree of filling of the base station aspirate chamber and/or at least one specific parameter for the filter and aspirate chamber and/or the base station filter and base station aspirate chamber. The filling degree is given, for example, as a percentage.

Preferably, the filling state of the base station separating device is determined by using the operating data of the base station and the operating data of the vacuum cleaner.

As the flow path state data, it is determined, for example, whether a flow path is completely closed or partially closed, to what extent the flow path is closed, or whether a flow path is completely established, for example, between the separation apparatus and the base station separation apparatus. In particular, the flow resistance of the flow path is determined, for example, as a function of the power level of the blower motor or the base station blower motor.

By transmitting the operating data of both devices, the operating data of the vacuum cleaner and the operating data of the base station can be correlated with one another and, for example, flow path state data of the individual flow paths, in particular of the flow path between the separating device and the base station separating device, can be determined therefrom.

The advantage of the invention over the prior art is that additional information can be derived by transmitting operating data and jointly evaluating the operating data, whereby in particular the number of sensors required in the system can be reduced.

For example, flow path status data of the base station or the filling status of the base station separation device is determined from the operational data of the vacuum cleaner in a regeneration operation. This is possible because the vacuum cleaner is fluidly connected to the base station, in particular to the base station separation apparatus, during regeneration operation. A separate sensor, in particular a pressure sensor, can then be dispensed with in the region of the base station separation device. The determination is preferably made using a base station, in particular a second data processing device.

Furthermore, for example, when the base station blower motor sucks away the separating apparatus of the vacuum cleaner, the filling state of the separating apparatus of the vacuum cleaner can be determined from the operating data of the base station blower motor of the base station. In this variant, in particular, the number of sensors in the vacuum cleaner can be reduced.

According to a first embodiment of the method, it is provided that the separation device comprises at least one filter. Alternatively or additionally, the base station separation device comprises at least one base station filter. The filter and the base station filter are preferably configured as permanent filters. It is also provided that the filter is designed as a permanent filter, while the base station filter is designed as a disposable filter, in particular as a disposable filter bag. The filter of the vacuum cleaner, which is designed as a permanent filter, is cleaned during a regeneration operation, for example in a filter bag of a base station. The filter is preferably arranged in the suction chamber of the vacuum cleaner. The base station filter is preferably arranged in a base station suction room of the base station.

The determined filling state of the separation device preferably comprises a filling degree of the filter, and the filling state of the base station separation device preferably comprises a filling degree of the base station filter, in particular as a special parameter. It is also envisaged that the filling state of the separating device comprises the filling degree of the filter and the filling degree of the aspirate chamber. It is also contemplated that the filling state of the base station separation unit includes the filling degree of the base station filter and the filling degree of the base station suction chamber. If the base station separation device is designed as a filter bag, the filling state comprises a specific parameter of the filling degree of the filter bag or of the filling degree of the filter bag.

According to a further embodiment of the method, it is found to be particularly advantageous to design the filling state of the separation device and/or the filling state of the base station separation device and/or the flow path state data to be determined by using the data of the characteristic line. For example, the operating data or the modified operating data is compared with the data of the characteristic line, or the data of the characteristic line and the operating data are correlated with each other.

The data of the characteristic line comprise, for example, reference data about the characteristic flow characteristics, in particular the flow characteristics, of the separating device, of the base station separating device, in particular the flow characteristics, and/or of the different flow paths in the system. Preferably, the above data is kept in place (bereitgelten) depending on the power level or the volume flow of the blower motor or the base station blower motor.

The data for the determined characteristic line preferably comprise data of a characteristic line of the vacuum cleaner and data of a characteristic line of the base station. The data of the characteristic line of the vacuum cleaner includes data of the characteristic line of the separating apparatus, such as pressure loss, and data of the characteristic line of the flow path, such as pressure loss over the entire flow path in the vacuum cleaner. The data of the characteristic line of the base station include, for example, data of the characteristic line of the base station separation apparatus, such as pressure loss, and data of the characteristic line of the flow path in the base station, such as pressure loss over the entire flow path in the base station.

The data of the characteristic line usually comprise, for example, the pressure loss over the separating device and/or the base station separating device depending on the power level of the blower engine or the volume flow in the system and depending on the degree of filling of the separating device or the base station separating device. It is further contemplated that the pressure loss is stored in dependence on other parameters of the blower motor or of the base station blower motor, for example in dependence on the engine speed and/or the power consumption.

The data of the characteristic line are stored, for example, as a set of points (punktescar) or as a function. Preferably, said pressure loss at the separation device or at the base station separation device is maintained as a function of the volume flow base station. It is furthermore envisaged that said pressure loss on the separating device or the base station separating device is maintained as a set of points depending on the power level of the blower motor or the base station blower motor.

According to a further embodiment of the method, the data for the determined characteristic line are selected in such a way that the filter and/or the base station filter comprise at least one identification means. The selection of data for determining the filling state of the base station separation device and/or the characteristic line of at least flow path state data of at least one flow path comprises evaluating the at least one identification device.

The filter and/or the base station filter comprise, for example, a bar code or an RFID chip as identification means, so that the type of filter or base station filter used of the base station or vacuum cleaner is identified by evaluating the identification means. Based on the identified filters or the identified base station filters, data of the characteristic lines of the individual filters or base station filters are selected and used by the base station or the vacuum cleaner for the determination.

A further embodiment of the method is designed in such a way that the data of the characteristic line are kept ready in the vacuum cleaner and/or the base station. The device performing said determining step has kept data of all necessary characteristic lines ready for use in the vacuum cleaner and the base station so that the determination can be started when operational data is present.

Alternatively or additionally, the data of the characteristic line are transmitted from the vacuum cleaner to the base station and/or from the base station to the vacuum cleaner. Thereby enabling the use of a vacuum cleaner not known to the base station or the use of a base station not known to the vacuum cleaner. Each device holds the data of its own characteristic line in readiness and, if necessary, can transmit it to the device which performs the determination step. The data of the characteristic line are preferably kept ready by the respective data processing device.

For example, the cleaner will retain the data of its characteristic line and transmit it to the base station when first connected thereto, so that it can be stored by the base station for later use with the cleaner. The data of the characteristic line is then transmitted only once during the first connection. The transmission of the data of the characteristic line is preferably carried out before the start of the regeneration operation, so that the data of the characteristic line is already available for determination during the regeneration operation.

In order to be able to adapt or change the data of the characteristic line, it is additionally or alternatively provided that the data of the characteristic line are transmitted to the vacuum cleaner or the base station via a data network or a data processing terminal via a first data interface of the vacuum cleaner or a second data interface of the base station. The data processing terminal is for example a smartphone or a tablet computer.

In determining the filling state of the separating device and/or the flow path state data of the base station, the data of the characteristic line have to be provided on the device (vacuum cleaner or base station) where the determination is made. For example, if the determination is made at the base station, at least during the determination, data such as the characteristic line of the base station and data of the characteristic line of the cleaner are both stored in the base station. For example, the base station is connected to the internet via a wireless local area network and can download data for its feature line from a server when in contact with a new cleaner.

It is also envisaged that the user may use a data processing terminal, such as a smart phone or tablet, for example, to transmit new characteristic data to the cleaner or base station by selecting on the data processing terminal. The data of these characteristic lines have been downloaded beforehand from a data processing terminal from a server via a data network, preferably the internet, for example.

For example, the user changes the filter or base station filter, and then confirms the filter change on the smartphone and selects the filter type to use. The smartphone then downloads the data of the associated characteristic line from the server and transmits the data of the characteristic line, for example, to the base station.

In this way, the data of the characteristic line can be managed centrally, for example on a server, and it can be ensured that the device performing the determination step always uses the data of the current characteristic line. It is also provided that the vacuum cleaner or the base station identifies the used filter or the base station filter by means of an identification device and then uses the data of the characteristic line or receives it via at least one data interface.

A further advantageous embodiment of the method provides that before the regeneration operation begins, the vacuum cleaner transmits at least identification data, in particular at least one serial number or at least one device identification number, to the base station. Based on the identification data, for example, the selection of the data of the characteristic line or the transmission of the data of the characteristic line is performed by using the identification data. On the basis of the identification data, the base station checks, for example, whether data of the characteristic line have been reserved for the cleaner. If the data of the feature line is not yet available, e.g. used before, the data of the feature line is requested from the server over the data network. As an alternative to this, the user receives an indication, for example in a smartphone application, that the data of the characteristic line still has to be downloaded or provided.

According to one embodiment of the method, the user's convenience of use is increased by displaying the filling state of the separating apparatus and/or the filling state of the base station separating apparatus and/or at least a part of the flow path data for the user on a display of the vacuum cleaner and/or a display of the base station. For this purpose, for example, the filling degree of the separating device and/or the filling degree of the base station separating device can be displayed to the user, so that the user can change when the filling is completed. For example, the fill status is displayed as a specific parameter in percentage form. The flow path status data is displayed, for example, by indicating to a user that a flow path has been established and is not blocked. The display device is for example a display or for example a color coded LED display.

According to a further embodiment of the method, the computing power of the data processing device to be reserved by the system can be reduced by determining the filling status of the separating apparatus and/or the filling status of the base station separating apparatus and/or the flow path status data only by the vacuum cleaner or only by the base station. The operating data required for the determination are transmitted only to the device, i.e. the base station or the vacuum cleaner, and are used there centrally for the necessary calculations within the framework of the determination step. The filling state or flow path data of the separating device or of the base station separating device is thus successfully determined only by the first data processing apparatus or only by the second data processing apparatus.

According to another embodiment, the required data is transmitted from the cleaner and to the cleaner or from the base station and to the base station by the cleaner comprising a first data interface and/or the base station comprising a second data interface for data transmission. The first and second data interfaces are preferably configured for data exchange using bluetooth, wireless local area network, Near Field Communication (NFC), and/or other wireless short-range radio technologies. In this way, the cleaner and the base station can exchange data or with another data processing terminal, such as a smartphone, or with other interfaces of a data network.

In particular, in order to improve the accuracy of the determined filling state and flow path state data, it is provided according to a further embodiment that the vacuum cleaner and/or the base station comprise a device for pressure measurement, a device for differential pressure measurement, a device for volume flow measurement and/or a device for determining engine parameters. In particular, the vacuum cleaner and/or the base station comprise at least one pressure sensor and/or at least one differential pressure sensor. The additional sensor information of the device described above supplements the operating data, so that a more accurate filter status or flow path status of the system can be determined.

The object stated at the outset is also achieved by a system comprising at least one vacuum cleaner and at least one base station. The vacuum cleaner comprises at least one blower and at least one separating device for the suction. The base station comprises at least one base station separating device for the aspirant. The separating apparatus is fluidly connected to the blower to receive suction during a suction operation of the cleaner. In the case of a regeneration operation, the cleaner is fluidly connected to the base station for conveying suction from the separation apparatus to the base station separation apparatus.

The system is constructed and arranged to perform one of the methods described above.

Detailed Description

For the description that follows, it is required that the invention is not limited to the exemplary embodiments and to all or a plurality of the described combinations of features, but that each individual partial feature of the/each exemplary embodiment is of importance for the subject matter of the invention even in isolation of all other partial features described in connection therewith and even in connection with any feature of the other exemplary embodiments.

Fig. 1 shows an exemplary embodiment of a system 1 comprising a vacuum cleaner 2 and a base station 3. In this exemplary embodiment, the vacuum cleaner 2 is configured as a self-propelled, electrically driven vacuum cleaner robot. In the exemplary embodiment, the vacuum cleaner 2 comprises a housing 4, in which housing 4 at least one blower 5 and at least one separating device 6 for suction 7 are arranged. The base station 3 comprises a base station blower 8 and a base station separating device 9 for the suction 7.

In this exemplary embodiment, the separation device 6 comprises a filter 6a and an aspirate chamber 6 b. During a suction operation of the cleaner 2, the separating apparatus 6 is fluidly connected with the blower 5 to receive suction 7 in the suction chamber 6 b. The flow path is in the process led out of the housing 4 of the vacuum cleaner 2 again via the suction nozzle 10, the suction chamber 6b, the filter 6a and the blower 5. In particular during regeneration operation, the suction nozzle 10 can be closed with a flap 11 relative to the suction chamber 6 b.

In fig. 1, the cleaner 2 is shown in a regeneration operation. The vacuum cleaner 2 is in this process connected fluidically to the base station 3, i.e. via the flow channel 12. The flow channel 12 serves to convey the aspirate 7 from the separating device 6, in particular the filter 6a and the aspirate chamber 6b, to the base station separating device 9, i.e. the base station filter 9a and the base station aspirate chamber 9 b. The conveyance of the suction 7 from the filter 6a and the suction chamber 6b to the base suction chamber 9b and to the base filter 9a takes place by means of the blower 5 and the base blower 8. The blower 5 and the base station blower 8 generate a regeneration air flow, as indicated by the arrows in fig. 1, which conveys the suction 7.

Fig. 2 shows a schematic flow diagram of an exemplary embodiment of a method 100 for operating the system 1 comprising the vacuum cleaner 2 and the base station 3. In the exemplary embodiment, the vacuum cleaner 2 is first connected 101 to the base station 3, wherein the connection 101 is both made fluidically by means of the flow channel 12 and by means of data communication.

Referring to fig. 1, data is processed on the cleaner 2 using a first data processing device 13 of the cleaner 2. The data processing is performed on the base station 3 by means of the second data processing device 14 of the base station 3. The first data processing device 13 and the second data processing device 14 comprise at least one processor and at least one memory, respectively.

The data communication connection between the vacuum cleaner 2 and the base station 3 is performed via a first data interface 15 of the vacuum cleaner 2 and a second data interface 16 of the base station 3. The first data interface 15 and the second data interface 16 are configured for communication via a wireless broadcast technology, here a wireless local area network.

Referring to fig. 2, after connecting 101 the dust collector 2 with the base station 3, the device identification number of the dust collector 2 is transmitted 102 to the base station 3 via the first data interface 15 and the second data interface 16. Since this is primarily the first connection 101 of the vacuum cleaner 2 to the base station 3, the data K of the characteristic line of the vacuum cleaner 2 is additionally transmitted 102 to the base station 3, i.e. via the first data interface 15 and the second data interface 16. The base station 3 stores the data K of the characteristic line of the vacuum cleaner 2 in addition to the data K of its own characteristic line for further use by means of the second data processing device 14. The data K of the characteristic line of the vacuum cleaner 2 contain data about the pressure loss at the filter 6a and the suction chamber 6b as a function of the volume flow and the degree of filling of the filter 6a and the suction chamber 6 b.

The regeneration operation is then started (as shown in figure 1) and the operational data of the cleaner 2 and the base station 3 will be acquired 103. In the process, the first data processing device 13 acquires the operating data of the vacuum cleaner 2, and the second data processing device 14 acquires the operating data of the base station 3.

During or after the regeneration operation, the operating data of the vacuum cleaner 2 are transmitted 104 to the base station 3, in particular to the second data processing device 14 of the base station 3. In this exemplary embodiment, the further processing of all data, in particular the determination 105, is performed with the base station 3, i.e. the second data processing device 14 of the base station 3.

The second data processing device 14 of the base station 3 determines 105 the filling status of the base station separation means 9 and the flow path status data of the flow channel 12. The determination 105 is also performed by using data K of the characteristic line of the cleaner, which has been transmitted 102 from the cleaner 2 to the base station 3 at the beginning.

Finally, the filling state of the base station separation device 9 and the flow path state data of the flow channel 12 are displayed 106 on the display device of the base station 3.

If the vacuum cleaner 2 is connected 101 to the base station 3, wherein the data K of the characteristic line of the vacuum cleaner 2 is not kept ready on either the vacuum cleaner 2 or the base station 3, the base station 3 is configured such that the data K of the characteristic line of the vacuum cleaner 2 is received by the server 18 via the second data interface 16 over the data network 17, for example the internet.

Alternatively, the data K of the characteristic line can also be obtained by the data processing terminal 19 (beziehen). The data processing terminal 19 is configured, for example, as a smartphone. For example, the second data processing device 14 requests data K of the characteristic line of the vacuum cleaner 2 from the data processing terminal 19 via the second data interface 16. The data processing terminal 19 loads the data K of the requested characteristic line of the vacuum cleaner 2 from the server 18 via the data network 17 and then transmits it to the base station 3 via the second data interface 16. If, for example, the filter 9a is used in the base station 3, the data K of its characteristic lines are not yet retained in the base station 3, the data K of these characteristic lines are equally requested via the second data interface 14.

The invention is not limited to the exemplary embodiments shown and described, but also comprises all embodiments having the same effect in the sense of the invention. It is particularly emphasized that the exemplary embodiments are not limited to all features in combination, but rather that each individual partial feature can also have inventive significance separately from all other partial features themselves. Furthermore, the invention is at present not limited to the combination of features defined in claim 1, but can also be defined by any other combination of some of the features of all the individual features disclosed as a whole. This means that in practice almost every single feature of claim 1 may be omitted or replaced by at least one single feature disclosed elsewhere in this application.
