Further comparable water treatment plants are known from DE 20210864U 1 and DE 102008033685 a 1.
Disclosure of Invention
It is an object of the invention to improve a method and a device of the type mentioned in the introduction.
This object is achieved by a method having the features of claim 1 and by a motor vehicle having the features of claim 6. Preferred embodiments of the invention are described in the dependent claims.
A method for collecting and utilizing water in a motor vehicle, wherein a hydraulic water collection device collects water and feeds a water collection tank, it is provided in a particularly important manner for the invention that the water is collected in a wheel housing and fed to the water collection tank. This makes it possible not only to collect water in the event of rain, as is done in the prior art, but also after a rain event, as long as there is moisture on the road surface. Water carried up by the tires from the road surface is sprayed into the wheel house and the water flowing down there is collected by means of grooves, funnels and other collecting means arranged in the wheel house and then transported to a water collecting tank. Thereby, the possible period of time during which water can be collected is significantly prolonged.
In a particularly preferred development of the invention, the water collected in the wheelhouse is checked in the amount collected per unit time and information about the moisture on the roadway is known therefrom. In this way, the method for collecting water is also used as a sensorial method for knowing the moisture of the traffic lane.
In a further development of the invention, the water collected in the wheel housing plate is fed to a UV-irradiation unit. The UV-irradiation unit cleans the water and also works without abrasion. Spores such as algae are killed and fine particles are bonded. Thereby significantly facilitating further filtration. In particular, it is then preferred to feed the water collected in the wheel housing plate to the first sensor after leaving the wheel housing plate and after passing through the UV irradiation unit and, based on the sensor results and other information, to the second sensor, the first filter or the outlet. The second sensor is then preferably also assigned a second filter. Cleaning is preferably carried out in multiple stages, wherein each possible filter is preferably assigned a sensor, so that it can be checked whether the water can be cleaned by the filter, or whether the water is likely to heavily foul the filter and is preferably fed to the outlet, or whether the filter cannot be cleaned further, so that the water is fed immediately to the next filter or its sensor.
In a further preferred embodiment of the invention, the water collection tank has a fill level sensor and the information from the fill level sensor is correlated with the sensor information, so that when the water collection tank is filled, the newly collected water is fed to the outlet and is no longer cleaned. Preferably, in this information case, the water is also delivered directly to the outlet after collection, so that the water is also no longer delivered to the UV-irradiation unit.
Another aspect of the invention relates to a motor vehicle having a device for collecting water and for using the collected water in the motor vehicle, wherein the device has a water collecting device and a water collecting tank, wherein the water collecting device is connected to the water collecting tank. According to the invention, in a motor vehicle, the water collection device is arranged in the wheel housing of the motor vehicle. In such a motor vehicle, water can also collect after a rain phase, i.e. always when there is moisture on the road surface which is picked up by the tires. This is done in part even when the road surface is assumed to be dry, as the tire also carries moisture up from the road surface.
For this purpose, a collecting groove is preferably provided in the wheel housing. Alternatively or additionally, funnels or other outlets may be provided in the wheel housing plate into which the water collected in the wheel housing plate collects and is then directed to a water collection tank. Preferably, for this purpose, the feed water collection device is provided with a pump by means of which water is conveyed from the cover plate to the water collection tank. The water collection tank is preferably arranged adjacent to the wheel housing plate. The guide path is thus short and an advantageous installation can be achieved.
In a further preferred embodiment of the invention, a flow sensor is arranged between the water collection device and the water collection tank. The flow sensor measures the water flow or the amount of water per unit time flowing through the connecting line between the wheel house plate and the water collection tank. Thereby, it is possible to obtain information about moisture on the road surface.
In a further preferred embodiment of the invention, at least one filter is arranged between the water collection device and the water collection tank. Preferably, the filter is preceded by a sensor. The sensor may for example be a particle sensor. If there are particles that may clog subsequent units, such as filters or nozzles of a wiper system, the water is directed through the filters and cleaned. If no such particles are present, the water does not pass through the filter but is directed further. Water may also be fed to the outlet if it is determined that the contamination is too severe and cannot be cleaned by the filter.
It is particularly preferred that there are a plurality of filters which can be flowed through in succession, and that each filter is preferably preceded by a sensor, the collected water flow either passing through the filter or flowing to the outlet or to the next sensor depending on the measurement result of the sensor. Depending on the desired degree of treatment, different sensors and filters are used until the water finally reaches the water collection tank.
Preferably, the filter or filters are also preceded by a UV-irradiation unit, viewed in the transport direction. Before the water is fed to the filter, UV-irradiation is also carried out, under which spores and algae are killed and fine particles also adhere. The life of the filter is thereby significantly increased. Furthermore, the water collection tank preferably has a level sensor. The results of the level sensors are transmitted to the respective sensors and regulators so that water can be directed to the outlet when there is no subsequent filling need.
In a further preferred embodiment of the invention, the motor vehicle has at least one additional tank for receiving the additive, and the additional tank is connected to the water collection tank. Preferably, a plurality of additional tanks for accommodating different additives are provided. Depending on the desired degree of cleanliness and on the sensing result, it is thus possible to add additional additives to the water collection tank in the desired amounts and depending on the desired kind.
Deionized water (DI-water) can also be produced by corresponding treatment. The water collection tank is then preferably also connected to the motor control in order to be used as DI water and for corresponding injection into the motor. Another or other application is as cleaning water for cleaning windshields and headlamps.
Another aspect of the present invention is to provide a device for collecting water in a motor vehicle tank, wherein the device is installed in the motor vehicle to configure the motor vehicle accordingly and to contain the water in a wheel house.
Drawings
The invention will be further described below with the aid of an embodiment shown in the drawing. The sole figure shows a schematic representation of the method according to the invention and the water flow in a correspondingly equipped motor vehicle according to the invention.
Detailed Description
In the sole figure, a wheel house plate 1 is shown. The water that is picked up by the tires from the roadway is caught in the wheel house and collected by the water collection mechanism 2. The collected water is fed to the UV-filter 5 via a pipe system. On the way to the filter, the flow is measured with the flow sensor 3 and the result is sent to the vehicle control 4 and analyzed there. The wiper system 17 can thus also be controlled accordingly, since spray water and/or rain water reaching the windshield can be predicted. The collected water is supplied from the water collection device 2 to the UV filter 5 and is irradiated with UV light there. The UV irradiation unit, which may also be referred to as a UV filter 5, cleans the water and in particular also works without abrasion. Spores, algae and bacteria are killed. The fine particles are bound. Whereby the water can then be cleaned better subsequently with mechanical and other filters. After the UV filter 5, the water is fed to a first sensor 6. The first sensor detects whether water is needed and can be cleaned by the first filter 10. If so, the water is directed through the first filter 10 and then to the second sensor 7, which performs a similar check on the second filter 11. This process may be repeated a number of times until the nth sensor 8 and the nth filter 12. After being cleaned by the filters 10, 11, 12, the water thus cleaned is stored in a water collection tank 14. From the water collection tank 14, the water may be directed on to a wiper system 17, or other application in a motor vehicle. Another application may be in particular also the use as deionized water in motors of motor vehicles. The water collection tank 14 is supplemented, if necessary, with additives, such as a cleaning agent and/or an antifreeze agent, by a supplementary additional tank 15 and/or a further additional tank 16. The water collection tank 14 is also provided with a level sensor 11, which is connected to the entire device and in particular to the first sensor 6, the second sensor 7 and all the other sensors 8. If the water collection tank 14 is sufficiently filled, the water still to be cleaned is not fed to the respective filter 10, 11, 12, but to the outlet 9 (referred to as "outlet" in the figure). Also, the sensors 6, 7, 8 are provided with a logic which delivers water to the outlet 9 when it is determined that the degree of contamination is too high and cannot be cleaned.
All the features mentioned in the foregoing description and in the claims may be combined in any selected manner with the features of the independent claims. The disclosure of the invention is thus not limited to the described or claimed combinations of features, but rather all combinations of features which are advantageous within the scope of the invention are to be regarded as disclosed.
