Description

A WINDSHIELD WIPER FLUID FILLING ASSEMBLY

TECHNICAL FIELD

The invention relates to a windshield wiper fluid filling assembly for filling the windshield wiper fluid reservoir in vehicles.

BACKGROUND

Since the driver must be able to see the road clearly in order to dominate the road in vehicles, especially the windshield must remain clean at all times. To achieve this, there are windshield wiper fluid reservoirs in the vehicles. The fluid placed in these reservoirs is sprayed onto the windshield by a spray motor controlled by a driver-controlled control (windshield wiper arm). At the same time, the windshield wipers also operate and clean the glass together with the sprayed fluid.

The windshield wiper fluid can be quickly depleted due to the limited volume that the windshield wiper fluid reservoirs can have. Therefore, the windshield wiper fluid reservoir needs to be refilled frequently. The windshield wiper fluid reservoir is located under the motor hood in almost all available vehicles. Accordingly, in order to fill the windshield wiper fluid, first the motor hood is opened, then the lid of the windshield wiper fluid reservoir is opened and the windshield wiper fluid is filled here. In addition to being cumbersome, this is not a procedure that the driver can perform in all circumstances. For example, if the windshield wiper fluid is depleted on a highway, the driver will have to stop the vehicle for the filling process, and if there is no suitable area for stopping, road safety will be compromised. In addition, in such cases, the driver will need to keep extra fluid in the vehicle at all times.

Application numbered GB2276129A, known in the literature, describes a rainwater collection assembly for vehicles. Accordingly, rainwater is collected in the windshield wiper fluid reservoir by passing through the channels on the vehicle. At the same time, there is a filter to remove the dirt from the collected fluid. However, it is not specified how to clean the filter, it is mentioned that the filter may be a paper filter. The filter will have to be refreshed at regular intervals. This means extra cost and effort. All the problems mentioned above have made it necessary to make an innovation in the relevant technical field as a result.

BRIEF DESCRIPTION OF THE INVENTION

The present invention relates to a windshield wiper fluid filling assembly to eliminate the abovementioned disadvantages and to bring new advantages to the related technical field.

An object of the invention is to provide a windshield wiper fluid filling assembly in which reservoir filling is facilitated.

Another object of the invention is to provide a windshield wiper fluid filling assembly that does not need to be cleaned by the user.

Another object of the invention is to provide a windshield wiper fluid filling assembly in which the supply of windshield wiper fluid can be provided for the cleaning of the glass in all weather conditions.

To achieve all the objects mentioned above and which will emerge from the detailed description below, the present invention relates to a windshield wiper fluid filling assembly for filling at least one reservoir containing the windshield wiper fluid used to clean a vehicle glass by at least one windshield wiper, comprising at least one collection channel in which the fluid slipping from the vehicle glass is collected; at least one supply line to transfer the fluid collected in the said collection channel to the said reservoir; at least one filter to retain dirt and sediments in the fluid transferred from the said supply line to the reservoir; and at least one discharge line to discharge a greater amount of fluid than the capacity of the reservoir. Accordingly, its novelty is that the said discharge line is connected to the filter to provide a reverse flow to the flow in the supply line to clean the said filter by being exposed to the reverse flow. Thus, it is ensured that the fluid filtered through the vehicle glass is directed into the reservoir and collected here.

A possible embodiment of the invention is characterized in that it comprises at least one first arm and at least one second arm to connect the supply line to the collection channel from at least two different points. Thus, the reservoir is fed from two arms and filled faster.

Another possible embodiment of the invention is characterized in that the filter is a sand filter. Thus, it is ensured that the filter can be self-cleaned by reverse flow. Another possible embodiment of the invention is characterized in that it comprises at least one manual filling opening to fill the reservoir from a second nozzle other than the supply line. Thus, it is ensured that the reservoir can be filled from the second opening in a negative situation such as clogging that may occur in the supply line.

Another possible embodiment of the invention is characterized in that it comprises at least one distributor end to distribute the fluid in the supply line to the filter surface at the intersection of the supply line with the filter. Thus, it is ensured that the fluid in the supply line is distributed to the filter surface and the filter can be cleaned better by being subjected to reverse flow from a wider surface area.

Another possible embodiment of the invention is characterized in that it comprises at least one heating unit to heat the fluid in the reservoir. Thus, it is ensured that the fluid collected in the reservoir in cold weather is prevented from freezing by heating the fluid.

Another possible embodiment of the invention is characterized in that it comprises at least one additive dosing unit to allow predetermined amounts of various additives to be placed in the reservoir. Thus, for example, it is ensured that the fluid transferred into the reservoir in cold weather can be prevented from freezing with the addition of antifreeze.

Another possible embodiment of the invention is characterized in that the supply line comprises at least one check valve to allow flow only towards the reservoir. Thus, when there is more fluid supply to the reservoir than the capacity of the reservoir, the excess fluid is prevented from returning to the feed channel.

DETAILED DESCRIPTION OF THE INVENTION

In this detailed description, the subject of the invention is explained with examples that do not have any limiting effect only for a better understanding of the subject. Figure 1 shows a representative schematic view of the windshield wiper fluid filling assembly (10) of the invention. Accordingly, the windshield wiper fluid filling assembly (10) is used to provide fluid for cleaning at least one glass (20) on a vehicle. The glass (20) may be the front or rear glass (20) of a car. However, the vehicles on which the windshield wiper fluid filling assembly (10) can be positioned are not limited to cars. Any vehicle (such as a bus, truck, train, or ship) having a glass (20) cleaned by at least one windshield wiper (30) may be in question.

The said windshield wiper (30) can make a scanning motion on the surface of the glass (20) by contacting the glass (20), thus ensuring that the glass (20) is cleaned. The windshield wiper fluid filling assembly (10) contains at least one reservoir (60). The reservoir (60) is a cavity in which fluid can be put. The reservoir (60) is connected to at least one nozzle motor (62). The said nozzle motor (62) acts as a transfer to at least one nozzle (not shown in the figures) by pressurizing the fluid in the reservoir (60). The nozzle is positioned with the fluid outlet holes facing the glass (20). Thus, the fluid in the reservoir (60) is pressurized by the nozzle motor (62) and sprayed to the glass (20) by the nozzle. At the same time, the windshield wipers (30) become active and clean the glass (20) by sweeping on the glass (20).

The windshield wiper fluid filling assembly (10) of the invention contains at least one collection channel (40). The said collection channel (40) is the channel where the fluid flowing through the glass (20) is poured and collected. Accordingly, the fluid poured from any source on the glass (20) is filtered through the glass (20) by gravity and collected in the collection channel (40). The collected fluid may be, for example, windshield wiper fluid sprayed from the nozzles, rainwater or fluid spilled on the vehicle during washing.

The fluid collected in the collection channel (40) is transferred to at least one supply line (50). The said supply line (50) ensures that the fluid collected in the collection channel (40) is transferred to the reservoir (60). In a possible embodiment of the invention, the supply line (50) may comprise at least one first arm (51 ) and at least one second arm (52). The said first arm (51 ) and the said second arm (52) allow fluid to be transferred from at least two different points into the supply line (50) from the collection channel (40). In this way, the reservoir (60) is fed from more than one point and filled faster.

The windshield wiper fluid filling assembly (10) of the invention contains at least one heating unit (63). The said heating unit (63) provides heating of the fluid in the reservoir (60). In this way, it is ensured that the fluid in the reservoir (60) is frozen and the dirt on the glass (20) can be dissolved more easily with the hot water obtained. The heating unit (63) comprises at least one heating system motor (631 ) and at least one heat exchanger (632). The said heating system motor (631 ) enables the fluid in the reservoir (60) to be transmitted to the said heat exchanger (632). Accordingly, the fluid in the reservoir (60) is activated by the heating system motor (631 ) and sent to the heat exchanger (632). The temperature of the fluid is raised by giving heat to the fluid in the heat exchanger (632) and sent back to the reservoir (60).

The reservoir (60) is connected with at least one additive dosing unit (64). The additive dosing unit (64) includes a chamber in which additives such as cleaning chemicals and antifreeze can be placed. The additive dosing unit (64) allows the predetermined amount of additive to be transferred into the reservoir (60). In this way, a certain amount of additives can be transferred into the reservoir (60) according to the occupancy rate of the reservoir (60).

The reservoir (60) comprises at least one manual filling opening (61 ). The manual filling opening (61 ) is an opening that opens out of the reservoir (60) and closes with the cap. The manual filling opening provides a second access to the reservoir (60) outside the collection channel (40) so that the user can fill the reservoir (60) manually. In this way, it is ensured that the reservoir (60) can be filled from the second opening in case of a blockage that may occur in the supply line (50).

The reservoir (60) comprises at least one filtering chamber (70). The said filtering chamber (70) is positioned between the reservoir (60) and the collection channel (40), i.e. on the supply line (50). Accordingly, fluid from the supply line (50) passes through the filtering chamber (70) before entering the reservoir (60). The filtering chamber (70) comprises at least one filter (71 ). The said filter (71 ) is preferably the purifying sand filter (71 ). The sand filters (71 ) are known to act as filtering by holding the sediments for the flow from one direction, whereas the sediments remaining on the filter (71 ) can be removed by a flow from the opposite direction. Accordingly, the filter (71 ) provides filtering of the fluid from the supply line (50) to the reservoir (60). In this way, it is ensured that the fluid collected in the collection channel (40) and transferred to the reservoir (60) and the impurities contained in it are retained.

The windshield wiper fluid filling assembly (10) includes at least one discharge line (80). The said discharge line (80) is the line that allows the excess fluid in the reservoir (60) to discharge. Accordingly, when more fluid is delivered from the supply line (50) to the reservoir (60) than the capacity of the reservoir (60), the excess fluid is removed from a discharge end (81 ). In the windshield wiper fluid filling assembly (10) of the invention, the fluid in the discharge line (80) passes through the filtering chamber (70) before it reaches the discharge end (81 ). Accordingly, the filtering chamber (70) is connected to both the supply line (50) and the discharge line (80). The reverse flow to the supply line (50) in the discharge line (80) allows the filter (71 ) to be cleaned. Accordingly, while the fluid in the supply line (50) is cleaned by the filter (71 ), the filter (71 ) itself is cleaned by the fluid in the discharge line (80). The discharge line (80) comprises at least one distributor end (82). The said distributor end (82) is located at the intersection of the supply line (50) with the filter (71 ). The distributor end (82) allows the fluid in the discharge line (80) to be distributed along the surface of the filter (71 ). Thus, the surface of the filter (71 ) is subjected to reverse flow from a wider area, and the filter (71 ) is better cleaned.

There is at least one check valve (53) on the supply line (50) to allow only direct flow to the reservoir (60). With the said check valve (53), the reservoir (60) is prevented from returning to the supply line (50) when it is exposed to more fluid supply than its capacity. Thus, the excess fluid is directed to the discharge line (80).

In light of all these explanations, the inventive windshield wiper fluid filling assembly (10) performs its function as follows: The fluid coming on the glass (20) flows into the collection channel (40) by filtering by gravity. Fluid flows from there into the first line (51 ) and the second line (52) and the supply line (50). The fluid in the supply line (50) passes through the filtering chamber (70) and the filter (71 ) and is free from dirt and sediments in it. The fluid thus reaches the reservoir (60) in the cleaned state and accumulates there.

The excess fluid in the reservoir (60) cannot return due to the check valve (53) in the supply line (50), instead, it is directed to the discharge line (80). The fluid in the discharge line (80) is passed through the filtering chamber (70) and the filter (71 ) before being discharged from the discharge end (81 ). The fluid in the discharge line (80) thus allows the filter (71 ) to be cleaned with reverse flow. The distributor end (82) distributes the fluid in the discharge line (80) to a wider area on the filter (71 ), enabling better cleaning of the filter (71 ).

When the reservoir (60) is filled with precipitation in a cold climate, the problem of freezing may occur because the filled fluid will not contain antifreeze. The windshield wiper fluid filling assembly (10) provides heating of the reservoir (60) with the heating unit (63) it contains. In this way, when the reservoir (60) is filled with precipitation, the fluid in the reservoir (60) can be prevented from freezing. With the additive dosing unit (64), antifreeze can be added to the reservoir (60) for precipitation in cold climates. In addition, it is ensured that the chemicals that will ensure better cleaning of the glass (20) can be transferred into the reservoir (60) with the additive dosing unit (64).

The motor hood does not need to be opened to fill the windshield wiper fluid with the windshield wiper fluid filling assembly (10). When the users want to add windshield wiper fluid, they can add the fluid by pouring fluid into the collection channel (40). Apart from this, if desired, addition can also be made from the manual filling opening (61 ).

With the windshield wiper fluid filling assembly (10) of the invention, it is ensured that the windshield wiper fluid sprayed on the glass (20), rainwater, and fluid used in car washing are recycled and reused as windshield wiper fluid. However, the self-cleaning structure of the filter (71 ) with the reverse flow does not necessitate the user to clean the filter (71 ) separately and to change it frequently.

The scope of protection of the invention is specified in the attached claims and cannot be limited to those explained for sampling purposes in this detailed description. It is evident that a person skilled in the art may exhibit similar embodiments in light of the above-mentioned facts without drifting apart from the main theme of the invention.
