Definitions
- the invention relates to a cleaning device for a vehicle, a vehicle with such a cleaning device, a first and a second use, and a cleaning method for a vehicle.
- a vehicle is to be understood as any type of vehicle which is operated either with an internal combustion engine and / or with an electric motor, but in particular passenger cars and / or commercial vehicles. These are preferably partially autonomous and, in particular, fully autonomously operated vehicles.
- An object of the invention is to enable improved vehicle cleaning. Another object on which the invention is based is to improve a cleaning device for a vehicle.
- a cleaning device proposed according to claim 1 and placed under protection A vehicle with such a cleaning device is also proposed and placed under protection (see. Claim 7). Furthermore, the use of a pump-compressor stage and the use of the proposed cleaning device are proposed and protected (cf. claims 8 and 9). Furthermore, a cleaning method for a vehicle is proposed and placed under protection (see. Claim 10). In addition, a computer program and a computer program product for performing the cleaning method is proposed and placed under protection (see. Claims 12 and 13). Advantageous embodiments of the invention are the subject of the subclaims.
- a cleaning device for a vehicle is proposed with which at least one cleaning point of the vehicle can be optionally pressurized. ter cleaning liquid and / or pressurized ambient air can be cleaned.
- the proposed cleaning device includes:
- a fluid distribution device downstream of the pump-compressor stage which can be fed through the pump-compressor stage with the pressurized cleaning liquid and / or the pressurized ambient air, the fluid distribution device being fluidically connected to the cleaning point.
- a cleaning point can be understood to mean a cleaning point assigned to a vehicle sensor - for example a cleaning point assigned to a camera, etc. - whereby the cleaning point as such can even be part of the respective vehicle sensor or can be arranged at a distance from it, for example a point on a windshield and the like.
- a cleaning point can also be another point on the vehicle which as such is not assigned to a vehicle sensor, for example another point on said windshield, a point on a headlight and the like.
- a cleaning liquid can be understood to mean water, but advantageously an aqueous cleaning agent solution, ie water in conjunction with a cleaning agent additive.
- the cleaning liquid can also advantageously contain an antifreeze or antifreeze agent, which as such lowers the freezing point of the cleaning liquid.
- ambient air can also be understood to mean the air of a vehicle interior, which is expediently filtered and possibly also preheated air.
- an already in an HVAC system Heating, ventilation, air conditioning
- air filters provided for air conditioning
- the proposed cleaning device reduces the number of components required for such a device. It thus simplifies such a device. This also reduces the cost of such a cleaning device. Since the pump-compressor stage is designed both to convey the cleaning liquid and to convey the ambient air, there is no further, separately fluid-conveying component for conveying either the cleaning liquid or the ambient air, along with an associated, separately fluidic connection of the component to the device. This also simplifies the control of such a cleaning device because fewer components need to be controlled.
- the pumping of ambient air also counteracts the formation of a biomass in the fluid path and thus also the resultant digestion of the fluid path. Ideally, both the formation of biomass and digestion are completely prevented.
- a range of a used amount of cleaning liquid is significantly increased compared to a device which as such only conveys cleaning liquid.
- either a cleaning fluid branch and / or an ambient air branch of the fluid path can optionally be blocked and / or released by means of blocking and releasing means in the fluid path.
- At least one separate release and shut-off means for example in the form of a release and shut-off flap, can be assigned to the cleaning fluid branch and the ambient air branch.
- a multi-way valve can be arranged between the cleaning fluid branch and the ambient air branch, which optionally provides either a cleaning fluid feed and / or a Enables training air conveyance or switches between these two conveyance modes of the device.
- a centrally acting switchover valve could also save installation space.
- the pump-compressor stage be driven electrically, the pump-compressor stage advantageously being easily controllable with regard to the respective fluid-specific delivery requirement.
- the pump-Ver denser stage can be designed in the form of a displacement pump stage and / or a flow pump stage.
- a use of the aforementioned pump-compressor stage is proposed for the optional suction and delivery of either a cleaning liquid and / or ambient air and for pressurizing a fluid path leading to a fluid distribution device, the fluid distribution device being fluidically connected to at least one cleaning point of the vehicle .
- a cleaning method for a vehicle is proposed in which at least one cleaning point is optionally cleaned with pressurized cleaning fluid and / or pressurized ambient air.
- Fig. 2 shows the cleaning device shown in Fig. 1 during a
- Fig. 3 shows the cleaning device shown in Fig. 1 during a
- the proposed cleaning device 2 has a fluid delivery unit 4, which has a pump-compressor stage PVS, for example in the form of a flow pump stage, and an electrical system that drives the pump-compressor stage PVS.
- the motor 14 includes.
- the electric motor 14 drives a pump / compressor impeller or pump / compressor delivery wheel 18 via a shaft 16.
- the flow pump stage this is, for example, a side channel pump impeller and / or a peripheral channel pump impeller.
- a pump-compressor stage housing 20 accommodating the impeller or feed wheel 18 is fluidically connected to a fluid distribution device via an outflow connection 22 from which a fluid line (not shown here) leads away.
- Said pump-compressor stage PVS can be designed, for example, in the form of a centrifugal pump.
- the respective cleaning medium or fluid is fed to a plurality of possible cleaning points of a vehicle via the fluid distribution device.
- This can be cleaning points assigned to a vehicle sensor - for example a cleaning point on a windshield etc. assigned to a camera - and / or other cleaning points, for example another point on the windshield, a point of a headlight and the like.
- the pump-compressor stage housing 20 is also connected via an inflow connection to a fluid path 8, which fluidly connects the pump-compressor stage PVS on the one hand to a cleaning fluid container 6 and on the other hand to an environment U of the cleaning device 2.
- the fluid path 8, via which either a cleaning liquid and / or an ambient air can be conveyed as required and optionally, comprises a cleaning liquid branch 8a and an ambient air branch 8b, which as such merge or diverge at a branching point or bifurcation point of the fluid path 8 .
- an air filter - not shown in the figures - can advantageously also be provided in the ambient air branch 8b towards the environment.
- the filtered ambient air can be either air drawn in from the surroundings of the vehicle and / or air drawn in from the interior of the vehicle (see also the introductory definition of ambient air).
- the cleaning fluid branch 8a and the ambient air branch 8b are each assigned a separate release and shut-off means, for example in the form of a release and shut-off flap 10, 12, which releases and / or blocks the respective branch to selectively to enable either a desired delivery of cleaning liquid and / or a desired delivery of ambient air.
- a multi-way valve between the cleaning fluid branch 8a and the ambient air branch 8b can be arranged accordingly adjustable, whichever needs and optionally either the desired one Cleaning liquid enables keitsefficiency and / or the desired conveying of ambient air or switches between these conveying modes of the device 2 accordingly.
- the cleaning device 2 is part of a vehicle, preferably in the form of an at least partially autonomous, but in particular fully autonomously operated vehicle.
- either said cleaning liquid and / or said ambient air can optionally and if necessary be supplied to at least one of the named cleaning points under pressure.
- the proposed cleaning device 2 eliminates the need for two separate fluid delivery units in addition to the respective, separately fluidic connections to the device 2. As a result, the proposed cleaning generation device 2 the number of required components of such a device and thus the cost of the device.
- the speed of the impeller / conveyor wheel 18 is adapted to the respective ambient air-specific pumping requirement so that the blowing of the respective fluid path on the one hand and the cleaning of the respective cleaning point by means of pressurized ambient air on the other hand are at least effective.
- the range that can be achieved with the cleaning liquid of the cleaning liquid container 6 can be significantly increased according to the invention.
