, Description:[0001] DESCRIPTION OF THE INVENTION:
[0002] The following specification particularly describes the invention and the manner in which it is to be performed:
[0003] Technical Field of the Invention
[0004] The subject matter described herein, in general, relates to a windshield wiper and washer system and in particular, relates to a wiper and washer system capable of removing raw egg stains from the windshield of a vehicle.
[0005] Background of the Invention
[0006] In order to keep a good visibility whilst driving a vehicle during various weather conditions and to keep a windshield clear from any debris or dirt, a device known as a windshield wiper is employed. Along with the windshield wiper, a washer system for spraying water and/or an antifreeze agent on the windshield is in place that increases the ability of the windshield wiper to remove any stains or dust from the windshield.
[0007] In recent years, many incidents have taken place wherein eggs are thrown on the windshields of vehicles, especially at night, with an intention of robbing a driver of the vehicle. When an egg hits and spreads on the windshield, the driver tries to wipe it off using a conventional windshield wiper and washer system. The driver sprays water on the windshield and operates the wiper in an attempt to remove the raw egg. However, the egg becomes milky and blocks the vision up to 92.5% when mixed with water. As a result, the driver is forced to stop the vehicle at the roadside for cleaning the windshield manually. Upon stepping out of the vehicle, the driver becomes a victim of robbers and in many instances meets with fatal consequences.
[0008] Hence, there is a need to provide a wiper and washer system that is capable of efficiently removing raw-egg stains from the windshield of a vehicle, once the windshield has been stained by raw eggs.
[0009] DE 102009012010A1 discloses a mixing device comprising a multi-chamber concentrate storage container for receiving different liquid concentrates, such as an anti-freezing agent and cleaning solutions. The anti-freezing agent flows from the agent chamber into a washing water container via a tube whenever a temperature of water in the washer tank is close to zero or below freezing point. The cleaning solutions flow from washing concentrate chambers of the storage container into the mixing device. The cleaning solutions are mixed therein with water and sprayed on the windshield of the vehicle whenever a washer mechanism is activated manually or automatically.

[0038] Detailed Description of the Invention
[0039] The following presents a detailed description of various embodiments of the present subject matter with reference to the accompanying drawings.
[0040] The embodiments of the present subject matter are described in detail with reference to the accompanying drawings. However, the present subject matter is not limited to these embodiments which are only provided to explain more clearly the present subject matter to a person skilled in the art of the present disclosure. In the accompanying drawings, like reference numerals are used to indicate like components.
[0041] The subject matter described herein relates to an Egg swindle wiper and washer system for a vehicle. Figure 1 illustrates an exploded view of an Egg swindle wiper and washer system 102 for a vehicle 100 in accordance with one embodiment of the present subject matter. The Egg swindle wiper and washer system 102 according to the present subject matter includes a plurality of components. For example, and by no means limiting the scope of the present subject matter, the Egg swindle wiper and washer system 102 includes a reservoir or tank 104 that is disposed under a bonnet 106 of the vehicle 100. The tank 104 is provided with at least two compartments 108, 110 for storing at least two cleaning fluids different from each other. The at least two compartments 108, 110 are separated from each other by a separation wall 112 and have respective filling openings. In a preferred embodiment of the present subject matter, the tank 104 is partitioned into a first compartment 108 and a second compartment 110 separated by the separation wall 112. The first compartment 108 is utilized for storing water and the second compartment 110 is utilized for storing a fluid capable of cleaning raw egg stains. In a preferred embodiment of the present subject matter, the fluid for cleaning raw egg stains is a mixture of vinegar, isopropyl alcohol and water. The first compartment 108 and the second compartment 110 have their respective filling openings for filling the respective fluids i.e. water and the cleaning fluid. For the purpose of the present description, the expressions ‘cleaning fluid’ and ‘cleaning solution’ are interchangeably used hereinafter.
[0042] The tank 104 is fluidly connected to a pair of nozzles 114 through a washer tube 116 for supplying water from the first compartment 108 or the cleaning solution from the second compartment 110 to the pair of nozzles 114. The pair of nozzles 114 is disposed on a top portion of the bonnet 106 and is capable of spraying water as well as the cleaning solution selectively on the windshield 118. The washer tube 116 is bifurcated into two tubes 120 for connection with the pair of nozzles 114.
[0043] At least one windshield wiper 128 is deployed to wipe off water or the cleaning solution or both water and the cleaning solution from the windshield 118 of the vehicle 100. In the embodiment depicted in Figure 1, two windshield wipers 128 are provided. Each of the windshield wipers 128 comprises a wiper arm 122 mounted on the vehicle and a wiper blade 124 attached to the wiper arm 122. The windshield wipers 128 remove water and/or the cleaning solution along with dirt and/or the raw-egg stains by a swinging back and forth motion on the surface of the windshield 118. The back and forth swinging motion of windshield wipers 114 is propelled by a wiper motor 126 disposed under the bonnet 106 of the vehicle 100. The wiper motor 126 is connected to the windshield wipers 128 by means of a wiper link 130. The wiper link 130 converts the rotational motion of the wiper motor 126 to the back and forth swinging motion of the windshield wipers 128.
[0044] Figure 2 illustrates a perspective view of the tank 104 of the Egg swindle wiper and washer system 102 in accordance with one embodiment of the present subject matter. As seen in Figure 2, the tank 104 is partitioned into the first compartment 108 and the second compartment 110 by the separation wall 112. In an embodiment of the present subject matter, the tank 104 has at least two filling openings, one for each of the first compartment 108 and the second compartment 110. In a preferred embodiment, the first compartment 108 comprises 75% of the overall volume of the tank 104 and contains water whereas the second compartment 110 comprises 25% overall volume of the tank 104 and contains the cleaning solution. However, the proportion of the overall volume of the tank 104 occupied by the first compartment 108 and the second compartment 110 is subject to modifications. For example, in another embodiment, the first compartment 108 occupies 70% of the overall volume of the tank 104 and the second compartment 110 occupies 30% of the overall volume of the tank 104. The cleaning solution comprises a mixture of water, isopropyl alcohol and white vinegar. In a preferred embodiment, the cleaning solution is a mixture of water (45% by weight), Isopropyl Alcohol (5% by weight) and White Vinegar (50% by weight).
[0045] A switch valve 132 as shown in Figure 2 is attached within the exit of the tank 104 to facilitate the flow of water or the cleaning solution from the first compartment 108 or the second compartment 110 respectively to the pair of nozzles 114.
[0046] The flow of water or the cleaning solution from the tank 104 to the pair of nozzles 114 is initiated by actuation of a push mechanism or a pull mechanism respectively. The push mechanism or the pull mechanism is actuated by a wiper lever 134, depicted in Figure 3, located at the right side of the steering column of the vehicle 100 just behind the steering wheel. Figure 3 illustrates a process for activation of an Egg swindle wiper and washer system 102 in accordance with one embodiment of the present subject matter. When a driver of the vehicle 100 manually activates a push mechanism (not shown in Figure 3) by pushing a wiper lever 134 away from him as shown by arrow 136, the push mechanism activates the switch valve 132 to initiate the flow of the cleaning liquid from the second compartment 110 of the tank 104 to the windshield 118 through the washer tube 116, tubes 120 and the pair of nozzles 114. When the switch valve 132 is activated by actuation of the push mechanism, a plunger 138 housed in the switch valve 132 is axially pulled up by an electromagnetic force generated by an energized coil 144. This results in opening of a drain channel 140, thereby resulting in draining of water and hence, decrease in the pressure. Consequently, the pressure from the upstream forces a diaphragm 146 to move up, thereby resulting in opening of the switch valve 132. As a result thereof, the cleaning solution flows to the plurality of nozzles 114 through the washer tube 116 and tubes 120 in order to be sprayed on the windshield 118. The windshield wiper 124 is deployed to wipe off the cleaning solution along with raw-egg stains from the windshield 118.
[0047] In order to clean the windshield 118 from dirt and the like, the driver activates the pull mechanism (not shown in Figure 3) by pulling the wiper lever 134 towards him, as shown by arrow 148. The actuation of the pull mechanism also activates the switch valve 132 to initiate the flow of water from the first compartment 108 of the tank 104 to the windshield 118 through the washer tube 116, tubes 120 and the pair of nozzles 114. The windshield wiper 124 then wipes off water along with dirt etc. from the windshield 118. The wiper lever 134 is located behind the steering wheel of the vehicle 100 so that it can be easily operated by the driver.
[0048] Figure 4 illustrates a flow diagram depicting the activation and use of an Egg swindle wiper and washer system 102 in accordance with one embodiment of the present subject matter. When a thug/robber throws an egg on the windshield 118 of the vehicle 100 in step 202, the windshield 118 becomes sticky and is covered with vision impairing raw-egg stain in step 204. In step 206, the driver activates the push mechanism by pushing the wiper lever 134 away and consequently, the switch valve 132 gets actuated by the electromagnetic force to spray the cleaning solution stored in the second compartment 110 on the windshield 118. In step 208, the cleaning solution passes through the washer tube 116, tubes 120 and the pair of nozzles 114. In step 210, the cleaning solution is sprayed on the windshield 118 through the pair of nozzles 118 and the windshield wipers 128 wipe off the cleaning solution along with remains of the raw egg stain from the windshield 118.
[0049] The steps described in Figure 4 above are explained in relation to the cleaning solution. However, steps 206, 208 and 210 can also be implemented for cleaning dirt etc. from the windshield 118 by utilizing water from the first compartment 108. In such a case, the driver activates the pull mechanism by pulling the wiper lever 134 towards him in step 206.
[0050] Although the invention has been described with reference to specific embodiments, this description is not meant to be construed in a limiting sense. Various modifications of the disclosed embodiments, as well as alternate embodiments of the invention, will become apparent to persons skilled in the art upon reference to the description of the invention. It is therefore, contemplated that such modifications can be made without departing from the spirit or scope of the present invention as defined.
