Description

The invention relates to a portable commercial dry vacuum cleaner with a housing which has a display device which is controlled by control electronics, the dry vacuum cleaner being specially designed for the needs of hotels, offices, retail and / or professional building cleaners.

In the case of a first problem, it is important for portable commercial dry vacuum cleaners that, for example, the affiliation of the dry vacuum cleaner to a specific building cleaner or cleaning company and / or to the company of a customer is clearly recognizable.

As a rule, the portable commercial dry vacuum cleaners change their place of use relatively frequently, in contrast to the vacuum cleaners used in private households. The building cleaner is among other things important to draw attention to his company name about the equipment used.

Portable commercial vacuum cleaners are therefore often provided with a sticker with the logo of the building cleaner and other personalized information (e.g. with a telephone number or address of the building cleaner, with a telephone number for the technical support service or for ordering consumables, etc.).

For very large cleaning companies, it is also common to affix the company logo and possibly other information directly onto the housing of the dry vacuum cleaner (e.g. printed with color).

The application of stickers is not very professional and it is relatively expensive to replace the sticker already attached to the dry vacuum cleaner if necessary. Long runs are required to apply a printed logo.

Another area of application for customer-specific logos and information is dealers or large trade organizations that want to advertise on the machines sold.

Another challenge associated with commercial dry vacuum cleaners is that they are often operated by migrant cleaners who are poor at e.g. understand the German language. This results in communication problems and thus inevitably difficulties in operating a dry vacuum cleaner, if, for example, a malfunction has occurred or a vacuum cleaner bag needs to be changed.

Another challenge arises from the fact that modern commercial dry vacuum cleaners usually have a device for automatically switching off the dry vacuum cleaner when it is determined that its motor is overheating. This leaves a user of the dry vacuum cleaner irritated, because he does not know how to proceed with the dry vacuum cleaner. First of all, the user will think that the machine is broken because it went out suddenly and cannot be switched on again when overheated.

A natural reaction of the user is often to wait a few minutes and switch the vacuum cleaner on again. If the vacuum still does not work, e.g. because the waiting time was too short to cool the dry vacuum cleaner sufficiently, the user or customer assumes that the vacuum cleaner is broken.

Another challenge with commercial dry vacuum cleaners arises from the fact that they also have to be manufactured very cost-effectively. It is not uncommon for commercial dry vacuum cleaners to be less expensive than commercially available private vacuum cleaners. This means that the manufacturer of commercial dry vacuum cleaners can install as few components as possible in his devices and must ensure that as few functions as possible of a commercial dry vacuum cleaner are covered with these few components.

To the above To accomplish challenges simultaneously or cumulatively, it is therefore the object of the present invention to firstly provide a portable commercial dry vacuum cleaner which in a simple manner and / or updates the multiple change of personalized information relating to the dry vacuum cleaner, in particular a current company logo of an operating company of the dry vacuum cleaner Information on the place of use of the dry vacuum cleaner, for example the company logo of the client and / or contact details of the bodies or persons responsible at the client, and (for large companies) the exact location of this dry vacuum cleaner, such as the plant, building, floor, etc.

This object is achieved according to the invention by the features of the independent protection claim. Further advantageous developments are the subject of the dependent claims.

• - ein Gehäuse,
• - wobei das Gehäuse des Trockensaugers eine Anzeigeeinrichtung aufweist, und
• - wobei die Anzeigeeinrichtung von einer Steuerungselektronik angesteuert wird.

According to the present invention, a portable commercial dry vacuum includes:

• - a housing,
• - The housing of the dry vacuum has a display device, and
• - The display device being controlled by control electronics.

The display device controlled by the control electronics preferably displays personalized information relating to the dry vacuum cleaner, in particular a current company logo of the building cleaner or the operating company of the dry vacuum cleaner and / or updated information on the place of use of the dry vacuum cleaner.

Thus, the affiliation of the dry vacuum cleaner to a specific building cleaner and / or to a company of a customer can be displayed using the display device.

This also makes it easy to display a logo of a building cleaner and other personalized information (e.g. with a telephone number or address of the building cleaner or the cleaning company, hotline number for the technical support service, etc.).

Furthermore, e.g. Stickers or printed information, such as dry vacuum cleaners from the prior art, are not laboriously and laboriously removed as soon as the dry vacuum cleaner e.g. changes its location.

It is also possible with the aid of the display device to provide cleaning staff who are currently operating the dry vacuum cleaner with instructions in their national language in the event of a malfunction, for changing a vacuum cleaner bag or for querying operating information (such as the running time since the last time the dust bag was changed, the total running time of the vacuum cleaner, etc.) to provide. Communication problems and difficulties in operating a dry vacuum cleaner can thus be prevented.

Furthermore, in the event of a forced shutdown before the motor of the dry vacuum cleaner overheats, an instruction or explanation, also in the national language, can be displayed, for example together with the display of the remaining time, i.e. a countdown to the proper cooling of the engine.

As a result, the above-mentioned challenges can be overcome simultaneously by the portable commercial dry vacuum cleaner according to the invention.

It is further preferred that the display device is designed with a touch-sensitive display for inputting control commands to the dry vacuum cleaner and / or for inputting information. In this way, inputs or control commands can be made using the finger of a user via the display device or communicated to the control electronics.

The display device is advantageously designed with a menu for operating and / or maintaining the dry vacuum cleaner. Thus, a user can operate the dry vacuum cleaner through the menu or receive help for its maintenance.

Furthermore, it is advantageous if the menu for operating and / or maintaining the dry vacuum cleaner can be displayed in different languages on the display device. The use of the display device, which is designed and designed to display more than the battery status or an error status (e.g. a red light is on), solves the three problems mentioned above.

The control electronics of the display device are preferably designed such that a language of the menu preferred for the user of the dry vacuum cleaner or better controlled by him can be set on the display device.

With the aid of the different languages, which can preferably be selected via the display device, it is possible that the portable commercial dry vacuum cleaner according to the invention can be used by changing cleaning staff of different nationalities and with different knowledge of the German language (for example in contrast to vacuum cleaners in private households). It is not uncommon for the cleaning staff to master only their original language. This means that the menu navigation in the dry vacuum cleaner can be easily changed to the language of the cleaning staff.

Furthermore, it is possible for the control electronics of the display device to be designed such that a language of the menu preferred for the user of the dry vacuum cleaner can be set on the display device without a new installation or without restarting a software of the dry vacuum cleaner used to control the display device. In contrast, commercially available smartphones, tablets or computers require that the operating software must be reinstalled or at least restarted after the user chooses a different language for the display of his device.

In this way, a language change can be carried out quickly and easily, the language change in the menu guidance in Dry vacuum cleaner according to the invention takes place by referring to another line or column in a language table for menu items which are not represented as symbols but as fonts. This means that no complete or partial reinstallation of software in the dry vacuum is required. Instead, it is possible to switch quickly between individual languages.

The dry vacuum cleaner is advantageously designed with a motor for generating a negative pressure in the housing of the dry vacuum cleaner.

It is also advantageous if the dry vacuum cleaner also has a control device for determining overheating of the motor. Thus, the dry vacuum cleaner is preferably capable of either completely deactivating the motor or reducing the motor output in the event of overheating for cooling purposes.

Furthermore, it is advantageous if the control electronics of the display device are designed in such a way that in the event of an overheating of the motor determined by the control device, a remaining time to run, i.e. a countdown to the proper cooling of the motor is displayed to the user of the dry vacuum cleaner on the display device. In this way it can be signaled to a user that the dry vacuum cleaner has no defect, but only that its motor has to cool down and that no repair service has to be called. This also prevents accidental “throwing away” of the dry vacuum cleaner. In this case, the display device of the remaining time also has the advantage that a cleaner can perform another activity within the time interval that is required for cooling.

In addition, it can be provided that the dry vacuum cleaner has a communication interface, in particular a Bluetooth interface and / or a USB interface, for data connection with an external electronic device, in particular with a smartphone.

The two interfaces mentioned can be found on almost every smartphone nowadays, which means that there is no need to integrate a separate communication device into the dry vacuum cleaner. After connecting e.g. Smartphone and dry vacuum cleaner can easily read information from a suitable app, installed on the smartphone, or played on the dry vacuum cleaner. Thus e.g. importing a new company logo from the smartphone to the dry vacuum is easy.

Alternatively or in addition to the above Bluetooth and / or USB interface, the dry vacuum cleaner can also be equipped with another communication interface. In a preferred case, this is a mobile radio interface which is operated with a so-called (U) SIM card. It does not have to be the latest version of the mobile radio interface (e.g. 4G or 5G). In view of the relatively small volume of the data transmitted to the dry vacuum cleaner or from the dry vacuum cleaner, it may be sufficient also the GSM or GPRS interfaces (i.e. 2G or 2G +) still supported in the mobile radio networks. In a preferred exemplary embodiment, the data can be exchanged with the dry vacuum cleaner using so-called SMS messages and / or data packets, preferably small data packets. A major advantage of SMS communication is that the SMS messages are “pushed” to the recipient until they arrive at the recipient. A similar quality mechanism can also be provided for data packet transmission. This ensures that communication with the dry vacuum cleaner takes place even if the dry vacuum cleaner has no network reception temporarily. The (U) SIM card required for mobile radio communication can preferably be installed directly in the dry vacuum cleaner.

The communication interface, in particular the Bluetooth interface and / or the USB interface, is preferably designed to transmit the personalized information relating to the dry vacuum cleaner, in particular the current company logo of the operating company of the dry vacuum cleaner and / or the updated information on the place of use of the dry vacuum cleaner.

It is also preferred that the Bluetooth interface and / or the USB interface is designed to receive personalized information regarding the dry vacuum cleaner from the external electronic device and / or to send it to the external electronic device.

Furthermore, it can be provided that the Bluetooth interface and / or the USB interface is designed to read out operating and / or maintenance information relating to the dry vacuum cleaner, in particular information relating to the total running time of the motor, the cleaning intervals, etc. For example, depending on the design of the dry vacuum cleaner, its remaining life cycle can be estimated without an expected defect. This makes it possible for a cleaning company, for example, to get a replacement in advance.

The Bluetooth interface and / or the USB interface is preferably designed to read operating and / or maintenance information relating to the dry vacuum cleaner by the external electronic device, in particular by the smartphone. In this way, the external electronic device can be used to send the read out information by radio (LTE, Wifi, etc.) to the owner of the dry vacuum cleaner or to the appropriate cleaning company. The cleaning company can then always evaluate current data or information on the dry vacuum cleaners used.

The dry vacuum cleaner also advantageously has a permanently installed or a removable device for storing the external electronic device, in particular the smartphone.

It is also advantageous if the device for storing the external electronic device, in particular the smartphone, is designed to be pluggable on a plug-on holder of the dry vacuum cleaner. This means that a smartphone can be securely attached or attached to the dry vacuum cleaner.

It is also advantageous if the USB interface is used to charge the external electronic device, in particular the smartphone.

The display device of the dry vacuum cleaner is advantageously designed to display machine-readable information, in particular a QR code or a bar code.

The machine-readable information displayed, in particular the QR code or the bar code, is preferably used to obtain further information from the Internet, for example an operating and / or repair instruction for the dry vacuum cleaner. This information can also be displayed in the respective national language of the cleaner who is currently using the dry vacuum cleaner, for example in the form of a brochure or a product sheet or in the form of a video.

Alternatively, the displayed machine-readable information, such as a QR code or a bar code, can also be used to make it easier when (re) ordering consumables or spare parts for the dry vacuum cleaner, for example if the QR code or the bar code is used with a smartphone app to be recognized and processed so that the order can then take place quasi-automatically.

In order to enable an efficient and data-saving transfer of information to and from the dry vacuum cleaner, regardless of whether the data is exchanged directly with the dry vacuum cleaner or indirectly with the help of an intermediate smartphone, the following procedure would be conceivable. For example, compressed data records - preferably daily - are exchanged with the dry vacuum cleaner for the purposes of comparison. For example compared on which day and which data a server received and saved from a specific dry vacuum cleaner. It is also checked whether additional data is stored on the dry vacuum cleaner itself. In a further comparison, the server communicates which data it already has and orders it to be deleted on the dry vacuum cleaner. The last day in the server database is still sent, since data could have been added here.
