Description
Technical Field
The application relates to a cleaning device, in particular a vacuum cleaner, comprising a housing, at least one suction motor, at least one suction channel and at least one suction filter. The suction motor is used in the suction channel to generate negative pressure in the negative pressure area for cleaning. In the flow direction after the suction motor, an overpressure is created, from which the suction air is usually released into the environment.
Background
Cleaning devices, in particular vacuum cleaners, are known from a number of prior art designs. The main function of a cleaning device, in particular a vacuum cleaner, with an air suction motor is to suck up suction material, such as dirt and particles, in the filter device in such a way that the suction material is sucked up in the negative pressure region of the air suction channel, for example by means of a suction tube. This suction air loaded to the suction material is cleaned by the filter means and the cleaned air leaves the cleaning device again.
In order to be able to perform special cleaning tasks, such as cleaning difficult to access areas, it is known in the art to expand the suction channel by means of accessory tools, such as small nozzles or cleaning brushes. Although the cleaning devices known in the prior art have been used in many ways, there is still a need for an extended cleaning solution.
Disclosure of Invention
The object of the present application is therefore to provide a cleaning appliance which is expanded in terms of application possibilities.
The above-mentioned object is achieved in a cleaning device of the type defined in the preamble of claim 1, in particular in a vacuum cleaner, in that at least one pressure vessel is present for cleaning with air flowing out of the pressure vessel, and that the pressure vessel can be connected to an overpressure zone of the suction channel.
The cleaning device is designed, for example, as a vacuum cleaner, in particular a hand-held vacuum cleaner, a vacuum cleaning robot or a vacuum cleaning robot. The cleaning apparatus generates at least one induced draft air flow in at least one induced draft channel when operated by the induced draft motor. By means of which suction air flow suction material, such as dirt and particles, in the suction channel can be sucked up in the negative pressure zone. The filter device is arranged in the suction channel in such a way that the suction air can be thoroughly cleaned off the suction material. In the flow direction downstream of the suction motor, an overpressure zone is formed in the suction channel, from where the suction air is released into the environment.
According to the application, it is now provided that the overpressure zone of the suction channel is connected or connectable to at least one pressure vessel, so that pressurized air can be stored in the pressure vessel and the user can use this air flowing out of the pressure vessel for cleaning purposes. By means of the pressure vessel, the outgoing air can be guided in a targeted manner to difficult access areas, such as narrow cracks and crevices, ventilation grilles of motor vehicles, blade areas of overedgers or keyboards of computers. Whereby dirt, in particular dust, is blown out and can then be sucked up by the usual suction function of the cleaning device.
The pressure vessel can be arranged on or in the housing of the cleaning device in such a way that the pressure vessel is in fluidic connection with the suction channelAnd (5) connection. In particular, the pressure vessel is arranged on the cleaning device in such a way that it can be at least temporarily supplied with air from the overpressure zone of the suction channel.
The pressure vessel is preferably designed to be closable relative to the suction channel, so that air under pressure can be stored in the pressure vessel, in particular when the suction motor is not in operation. By opening the vent valve of the pressure vessel, the user can use this air exiting the pressure vessel for cleaning purposes.
The application makes use of the idea that the overpressure which is always present in the overpressure zone is stored in the pressure vessel and used for cleaning purposes. The advantage is that the provision of an arrangement expenditure is reduced compared to a compressed air compressor; the advantages are re-usable and resource saving compared to compressed air sprayers.
According to a first embodiment of the cleaning device, the pressure vessel has a volume of between 0.05 and 0.5 liters. The volume is advantageously selected such that the air or suction air stored in the pressure vessel is suitable for approximately two to three air pressure shocks for cleaning before the pressure vessel has to be refilled on the cleaning device
According to one embodiment, it is also provided that at least one venting hose is arranged on the pressure vessel. The vent hose is removably or non-removably connected to the pressure vessel. For example, the vent hose may be coupled to a fluid port of the pressure vessel or to a vent valve of the pressure vessel. The outgoing air can be advantageously guided to a preferred cleaning position by means of an exhaust hose.
A further embodiment of the cleaning device provides that at least one air outlet connection for connection to the pressure vessel is formed on the housing. The exhaust connection is connected to the overpressure zone of the flow channel by means of a jet technology or an actuator is arranged in the flow channel, which actuator makes it possible to apply pressurized air to the exhaust connection. The exhaust gas connection preferably has at least one valve to close the exhaust gas connection.
The pressure vessel may preferably be coupled to the exhaust port or to the port. Through the exhaust interface, the pressure vessel can be connected directly to the downstream side of the suction motor by fluidic technology. Preferably, the valve present on the venting connection is opened by coupling to the pressure vessel, in particular to the fluid connection of the pressure vessel, and is closed again when the pressure vessel is decoupled.
According to a particularly preferred embodiment of the cleaning device, the pressure vessel is detachable from the cleaning device for independent use. In a state in which the pressure vessel is coupled to the cleaning apparatus, it is applied with pressurized air by the suction motor. The pressure vessel can be closed, for example by a valve, so that it can be taken out of the cleaning device together with the pressurized air and used independently for cleaning purposes, for example for blowing out crevices and cracks. The pressure vessel can be fixed, for example, in a form-fitting and/or force-fitting manner, to the housing of the cleaning device, so that it is held in a manner that is particularly mechanically protected from loss.
For example, a snap connection may be established between the cleaning device and the pressure vessel. Preferably, the pressure vessel is arranged flush with the housing surface of the cleaning device in a state in which it is arranged on the housing of the cleaning device.
According to a further embodiment of the cleaning device, the pressure vessel has at least one fluid connection. The fluid connection is in particular for connecting to an exhaust connection of a cleaning device. The fluid connection is provided only for applying pressurized air to the pressure vessel. In order to remove the pressurized air from the pressure vessel, the pressure vessel has, for example, a separate outlet valve.
Alternatively, it is also provided that the fluid connection is used for filling the pressure vessel, i.e. for applying pressurized air, as well as for cleaning, in such a way that the user again flows pressurized air out of the fluid connection for cleaning purposes.
According to a further embodiment, the pressure vessel has at least one vent valve. The vent valve is preferably operable by a user so that air can flow out for cleaning purposes. The exhaust valve is, for example, either constructed on the fluid connection or the fluid connection and the exhaust valve are constructed independently of one another. A vent valve arranged on the fluid interface is advantageously used for air outflow for cleaning purposes by the user.
A further embodiment of the cleaning device provides that the air outlet valve and/or the fluid connection is designed to be connected to an air outlet hose and/or a nozzle. The exhaust valve and/or the fluid connection is provided with at least one exhaust hose connection and/or one nozzle connection. By arranging the exhaust hose and/or the nozzle, the outgoing air can be guided in a targeted manner for cleaning purposes. For example, the nozzle connection is designed for a form-and/or force-fitting connection of the exhaust valve and/or the fluid connection to the nozzle.
It is also provided that the nozzle can be arranged or arranged at the end of the exhaust hose remote from the cleaning device. The discharge hose preferably has at least one nozzle connection.
According to a further embodiment, the usefulness of the pressure vessel can be increased in that the pressure vessel can be supplied with air from the overpressure zone of the suction channel manually and/or time-controlled and/or sensor-controlled. The cleaning device has, for example, at least one control device which acts on the air guiding device in the suction channel in order to apply the overpressure of air from the suction channel to the pressure vessel in a time-controlled and/or sensor-controlled and/or manual-controlled manner.
In the case of manual control, for example, it is provided that the user operates special buttons or touch screens on the cleaning device or on a control application, for example a smart phone, in order to supply the pressure vessel with outgoing air at the air outlet interface, in particular for loading the pressure vessel. The exiting air is then provided at the exhaust interface, either until shut down by the user or within a predetermined period of time.
It is also provided that air from the overpressure zone is provided time-controlled at the exhaust interface, for example for a period of time after the device has been opened and/or for a period of time after the pressure vessel has been arranged on the housing. In this way, for example after the start-up of the cleaning device, the pressure vessel is filled with pressurized air, so that it can always be put into use.
Furthermore, it is provided that air is supplied from the overpressure zone at the exhaust gas connection in a sensor-controlled manner, for example by means of a pressure sensor. In this case, it has proved to be particularly advantageous to provide at least one pressure sensor arranged in the cleaning device and/or at least one pressure sensor arranged in the pressure vessel. The pressure sensor in the cleaning device and/or the pressure sensor in the pressure vessel is preferably used to control the application of suction air to the pressure vessel.
For example, the application of air to the pressure vessel, in particular immediately after opening the cleaning device, is carried out until the pressure vessel is filled with a predetermined pressure, so that the existing valve is then closed and the pressurized air is enclosed in the pressure vessel.
Since the pressure vessel is connected to the suction channel in a jet technology, it is sufficient, for example, that only one pressure sensor is arranged in the cleaning device, where the pressure sensor can be connected more easily. However, it is also provided that at least one pressure sensor is arranged in the pressure vessel for transmitting a pressure signal, preferably to a control device of the cleaning apparatus. In particular, the pressure vessel is supplied with air from the overpressure zone until a predetermined pressure setpoint value is reached.
In order to control the supply of air from the overpressure zone, it has proven advantageous according to a further embodiment to provide the suction channel with at least one Y-valve (as a regulating device). The Y-valve is for example time-controlled and/or sensor-controlled, in particular pressure-sensor-controlled. In particular, the suction channel has at least one branching valve. Preferably, the Y-valve is configured such that suction air is discharged from the cleaning device while air is also applied to the pressure vessel.
It is also provided that the Y-valve is alternatively or additionally configured such that it is used to discharge suction air from the cleaning device or to apply air to the pressure vessel. The alternative supply of air to the pressure vessel or the discharge from the cleaning device is preferably controlled by a control device which actuates the respective actuator and valve, in particular the Y-valve. Preferably, the Y-valve may be controlled by a control means of the cleaning apparatus.
The Y-valve is thereby only temporarily switched for connecting the pressure vessel, so that the maximum back pressure (Staudruck) achievable by means of the suction motor is exerted in the pressure vessel without losses due to air flowing out in parallel through the exhaust opening of the cleaning device.
The pressure value in the pressure vessel can be monitored by a pressure sensor, for example in the cleaning device, in particular at the exhaust gas connection, and when the setpoint value is reached, the Y-valve can be switched by means of the control device in such a way that the usual exhaust gas outlet is released again during the cleaning operation. On the other hand, by operating the actuator, in particular the valve, the control device is responsible for retaining the air stored in the pressure vessel there.
According to a further embodiment of the cleaning device, it is advantageously provided that the cleaning device has at least one control device and that the control device is designed to operate the suction motor with a greater, in particular maximum, power in order to apply air to the pressure vessel. This embodiment is particularly advantageous in connection with the above-mentioned Y-valve. For example, after opening the cleaning device, in order to fill the pressure vessel with pressurized air, the control device is arranged to operate the cleaning device, in particular the suction motor, with maximum power for a certain period of time after opening, even if the user has selected, for example, only a medium power level for the cleaning device. It is also provided that the suction motor is operated at a greater power until a predetermined nominal value of the pressure in the pressure vessel is reached.
Preferably, the operation with greater power is provided independently of the power level selected by the user for the cleaning device. In this way, a maximum back pressure can be achieved and stored in the pressure vessel.
The control device is preferably arranged to operate the suction motor as a function of at least one measured value of at least one sensor, in particular a pressure sensor. For example, the control device controls the power of the suction motor and/or the Y-valve based on a pressure sensor in front of the exhaust interface in the suction channel and/or a pressure sensor in the pressure vessel.
The application also relates to a cleaning device having a housing, at least one suction motor, at least one suction channel and at least one suction filter, wherein the suction channel has an overpressure region and a negative pressure region during operation, wherein at least one exhaust connection for connection to a pressure vessel is formed on the housing. The exhaust connection can be connected to the overpressure zone of the suction channel in a jet-flow manner, for example by means of a Y-valve, which releases a corresponding flow path controlled by the control device. The venting connection can be closed, for example, and can be opened automatically, for example, by coupling the pressure vessel, and closed again when the pressure vessel is decoupled. In the embodiments described, further embodiments of the cleaning device are described.
Preferably, the cleaning device has at least one recess which is configured to at least partially, in particular completely, accommodate the pressure vessel. The pressure vessel can be accommodated at least partially, in particular completely, in the housing of the cleaning device, advantageously in the recess. For example, a holding device for holding the pressure vessel is provided on the cleaning device, in particular on the recess.
It is also provided that the cleaning device can accommodate and/or be used with a plurality of pressure vessels. Furthermore, it is provided that the cleaning device (even if there are a plurality of pressure vessels) has only one single air outlet connection or that the cleaning device has a number of air outlet connections corresponding to the number of pressure vessels.
The application also relates to a pressure vessel, in particular according to one of the embodiments, for connection to an exhaust interface of a cleaning device, in particular for arrangement on or in a housing of a cleaning device. Furthermore, the application relates to a system with a cleaning device according to one of the embodiments and a pressure vessel according to one of the embodiments.

Detailed Description
For the following description it is mentioned that the application is not limited to these embodiments and is not limited to all or a plurality of the features of the described feature combinations, rather that any individual sub-feature of the/each embodiment is also individually indicated to be separate from all other sub-features described in connection therewith and also to be combined with any feature of the other embodiments to represent the subject matter of the application.
Fig. 1 shows an at least partly sectional side view of a preferred embodiment of a cleaning device 1. The cleaning device 1 has a housing 2. An air suction motor 3 and an air suction channel 4 are arranged in the housing 2. The suction air guided in the suction channel 4 can be cleaned by the filter device 5. In the operation of the cleaning device 1, which is designed as a vacuum cleaner, the suction channel 4 has a negative pressure region 4a and an overpressure region 4b. At least one pressure vessel 6 is arranged on the housing 2 for cleaning with air flowing out of the venting vessel 6.
The pressure vessel 6 is inserted into a recess 12 in the housing 2 of the cleaning device 1 in such a way that it is arranged flush with the surface of the housing 2. In the state of being arranged in the housing 2, the pressure vessel 6 is connected to the suction channel 4 in such a way that it can be filled with pressurized air. For this purpose, the pressure vessel 6 is connected to the suction channel 4, in particular to the overpressure zone 4b, via a fluid connection 13 and a vent connection 7. When neither the pressure vessel 6 is coupled nor the pressure vessel 6 is filled, the venting connection 7 can be closed by a valve (not shown).
The fluid connection 13 furthermore has a manually operable outlet valve 14. For cleaning purposes, the air stored in the pressure vessel 6 can be discharged by the user via the outlet valve 14. In the present embodiment, the fluid connection 13 with the exhaust valve 14 can be used both for filling the pressure vessel 6 and for exhausting air. For example, the exhaust hose 6a or the nozzle 15 (see, for example, fig. 3) can be fastened to the fluid connection 13.
The cleaning device 1 can be guided by a user via a handle 9. In the present embodiment, the cleaning device 1 has a floor nozzle 10 which guides the suction channel 4 over the surface 11 in order to suck up suction material, such as dirt and particles, into the suction channel 4 by means of a negative pressure.
The cleaning device 1 also has a control device (not shown) which controls the suction motor 3 in such a way that, after the cleaning device 1 has been switched on for the first time, the suction motor 3 is either operated at maximum power for a period of time in order to fill the pressure vessel 6 with pressurized air or is operated at maximum power until a predetermined pressure is reached in the pressure vessel 6. The flow path to the usual outlet opening of the cleaning device 1 is preferably closed, for example by means of a Y-valve. The flow path to the outlet opening is then re-opened for normal cleaning operation and the pressurized air is stored in the pressure vessel 6 until it is used for cleaning.
In order to determine whether the pressure setpoint value in the pressure vessel 6 has been reached, a pressure sensor 8 is arranged in the flow channel 4, by means of which the pressure applied in the pressure vessel 6 can be detected as long as the flow path to the outlet opening of the cleaning device 1 is closed.
Fig. 2 shows another preferred embodiment of the cleaning device 1 with a housing 2. An air suction motor 3 is also arranged in the housing 2. The suction channel 4 extends in the housing 2 and has a suction zone 4a and an overpressure zone 4b. A filter device 5 is arranged in the suction channel 4 to thoroughly clean dirt and particles out of the suction air guided in the suction channel 4.
The pressure vessel 6 is in turn inserted into a recess 12 in the housing 2 of the cleaning device 1 in such a way that it is arranged flush with the surface of the housing 2. In the state of being arranged in the housing 2, the pressure vessel 6 is connected to the suction channel 4 in such a way that it can be filled with pressurized air. The pressure vessel 6 is connected to the suction channel 4, in particular to the overpressure zone 4b, via a fluid connection 13 and a vent connection 7.
In the present embodiment, the fluid connection 13 is only used for filling the pressure vessel 6. For cleaning purposes, the air stored in the pressure vessel 6 can be discharged via a discharge valve 14 which can be operated manually by the user.
The cleaning device 1 has a control device (not shown), which has been described in the embodiment of fig. 1. In order to determine whether the pressure setpoint value in the pressure vessel 6 has been reached, a pressure sensor 8 is arranged in the flow channel 4, by means of which the pressure applied in the pressure vessel 6 can be detected as long as the flow path to the outlet opening of the cleaning device 1 is closed.
Fig. 3 shows a further preferred embodiment of the cleaning device 1 with a housing 2. The design of this embodiment is the same as the embodiment of fig. 2. An air suction motor 3 is arranged in the housing 2. The suction channel 4 extends in the housing 2 and has a suction zone 4a and an overpressure zone 4b. A filter device 5 is arranged in the suction channel 4 to thoroughly clean dirt and particles out of the suction air guided in the suction channel 4.
In the present embodiment, the pressure vessel 6 is taken out of the recess 12 of the housing 2 of the cleaning device 1 and used for cleaning purposes. In the present embodiment, the pressure vessel 6 is filled with pressurized suction air via a fluid connection 13 on the exhaust connection 7 of the cleaning device 1. In the present exemplary embodiment, an exhaust hose 6a with a nozzle 15 is arranged on the exhaust valve 14.
By operating the discharge valve 14, the user can discharge the pressurized suction air out of the pressure vessel 6 through the discharge hose 6a and the nozzle 15. The exhaust hose 6a can also be used to reach places that are difficult to access in order to discharge the pressurized suction air in a targeted manner for cleaning.
The cleaning device 1 has a control device (not shown), which has been described in the embodiment of fig. 1. In order to determine whether the pressure setpoint value in the pressure vessel 6 has been reached, a pressure sensor 8 is arranged in the flow channel 4, by means of which the pressure applied in the pressure vessel 6 can be detected as long as the flow path to the outlet opening of the cleaning device 1 is closed.
The application is not limited to the examples shown and described, but also includes all embodiments which function identically in the sense of the application. It is emphasized that embodiments of the present application are not limited to combining all of the features together, rather each individual sub-feature, when separated from all other sub-features, is still of inventive significance. Furthermore, the application is not limited to the combination of features defined in claim 1 so far, but can also be defined by each of any different combinations of certain of all the individual features disclosed. This means that in principle each individual feature of claim 1 can be omitted in practice or can be replaced by at least one individual feature disclosed at other locations of the application.
