, Description:TECHNICAL FIELD

The present disclosure generally relates to the field of automobiles. Particularly, but not exclusively, the present disclosure relates to a demisting system in a vehicle. Further embodiments of the present disclosure disclose a system and method for demisting a windshield in a vehicle.

BACKGROUND

Safety is one of the biggest concern for any driver of a vehicle. A windshield plays a significant role on safety front. The windshield glass is specifically designed for automobiles to protect the driver and the passengers from any dirt, dust, and debris that could cause harm.

Generally, the windshield or windows are subject to condensation from passenger side when outside ambient temperature is low. The closed area of the cabin, along with the occupants breathing out moist air, tends to rapidly produce condensation on the inside of the glass of the windows. Also, in cold weather conditions, windshields may be subjected to frost and fog. The reason for this is the temperature difference between the inside of the vehicle and the ambient conditions. Thus, the condensation formed on the windshield is more than a cosmetic problem. When the windshield becomes foggy, it may obstruct the visuals of the road, vehicles and also pedestrians ahead of the vehicle. The driver who is driving the vehicle may be visually impaired of the things ahead of the vehicle as the windshield is frosted. As the driver is unclear of the road, vehicles and also pedestrians ahead of the vehicle, it may cause serious problems such as major accidents.

In the conventional system, demisting involves use of fresh air from the HVAC system of the vehicle for clearing the mist deposited on the surface of the windshield. The use of conventional systems requires heating or cooling of the fresh air and further directing the heated/cooled air onto the windshields. The heated/cooled air directed onto the windshield dissipates the mist formed on the windshield. The conventional systems cannot be used in the vehicles with no HVAC system present. Hence, the vehicles with no HVAC systems have to rely upon manual methods of clearing the fog on the windshields.

The present disclosure is directed to overcome one or more limitations stated above or other such relevant limitations associated with conventional art.

It is to be expressly understood, however, that each of the figures is provided for the purpose of illustration and description only and is not intended as a definition of the limits of the present disclosure. It will be readily understood that the aspects of the present disclosure, as generally described herein, and illustrated in the figures, can be arranged, substituted, combined, and designed in a wide variety of different configurations, all of which are explicitly contemplated and make part of this disclosure.

Embodiments of the present disclosure discloses a system and method for demisting a windshield in a vehicle. Unlike the conventional systems used for demisting the windshield, the system of the present disclosure uses compressed and dehumidified air from an air circulating unit associated with the auxiliary systems of the vehicle such as brake chamber which is already present in the vehicle. The demisting performance may be significantly improved with the system of the present disclosure. Also, the usage of the system of the present disclosure, does not require external use of fresh or heated air for clearing the mist deposited on an inner surface of the windshield.

In an embodiment, the system of the present disclosure includes an air circulating unit, a primary valve, a reservoir, a secondary valve and an electronic control unit [ECU]. The air circulating unit in turn includes an air compressor, a pressure regulator, an air drier, a brake chamber and a brake system air reservoir which may be associated with the brake chamber. The air circulating unit may be conventionally configured to direct the compressed air from the air compressor to the brake chamber or suspensions of the vehicle. The compressed air directed to the brake chamber from the air compressor may be stored in the brake system air reservoir of the air circulating unit at an optimum pressure. The compressed air stored in the brake system air reservoir may further be used in braking system to decelerate the vehicle and to bring the vehicle to standstill.

In an embodiment, a primary valve may be fluidly connected to the air circulating unit. Herein above and below, primary valve and bypass valve may be interchangeably used. The primary valve is configured to tap the compressed air from the air circulating unit to a demisting unit. In an embodiment, the primary valve taps the compressed air flowing from the air compressor to the brake chamber. Further, a reservoir may be fluidly connected to the primary valve. The reservoir is configured to store the compressed air that may be tapped from the air circulating unit by the primary valve. The primary valve may be associated with an Electronic Control Unit (ECU) and the ECU may be configured to selectively operate the primary valve to an open and a closed condition. The system of the present disclosure does not compromise with the safety of the vehicle i.e., the brake line is operated as a priority over the demisting system. Therefore, before operating the primary valve to the open condition, the ECU ensures that the brake system air reservoir associated with the brake chamber is at an optimum pressure. Conversely, if the brake system air reservoir pressure is below the optimum pressure, the ECU instantly restricts the primary valve from tapping the compressed air to the reservoir, thus ensuring that the braking performance of the vehicle is not affected. When the reservoir reaches its storage limit, the ECU restricts the flow of compressed air from the air circulating unit to the demist unit by operating the primary valve to the closed condition. Further, the compressed air stored in the reservoir may be released based on the requirement of demisting the windshields of the vehicle. In an embodiment, the compressed air may be released when a secondary valve which is fluidly connected to the reservoir may be operated to an open condition. The secondary valve in addition to the primary valve may also be associated with the ECU, wherein the ECU may be configured to operate the secondary valve to an open or a closed condition. The ECU may operate the secondary valve to open condition based upon the signal received to demist the windshields. Further, the released compressed air may be directed to a demisting vent through a desiccant chamber. The desiccant chamber may be configured to dehumidify the compressed air flowing through it. Further, the compressed and dehumidified air is directed to the demisting vents to demist the windshield. Additionally, the system includes a blower unit which may be in fluid communication with the reservoir and the demisting vents. The blower unit may be configured to accelerate the flow of compressed and dehumidified air from the reservoir to the demisting vents. In an embodiment, the compressed and dehumidified air may be directed to the side windows/windbreakers of the vehicle. The compressed and dehumidified air flowing out of the demisting vents ensures that the mist on the windshield and the side windows are swiftly dissipated.

While the disclosure is susceptible to various modifications and alternative forms, specific embodiment thereof has been shown by way of example in the figures and will be described in detail below. It should be understood, however that it is not intended to limit the disclosure to the particular forms disclosed, but on the contrary, the disclosure is to cover all modifications, equivalents, and alternative falling within the scope of the disclosure.

The terms “comprises”, “comprising”, or any other variations thereof used in the specification, are intended to cover a non-exclusive inclusion, such that an assembly that comprises a list of components or steps does not include only those components or steps but may include other components or steps not expressly listed or inherent to such setup or method. In other words, one or more elements in an assembly proceeded by “comprises… a” does not, without more constraints, preclude the existence of other elements or additional elements in the assembly.

Henceforth, the present disclosure is explained with the help of one or more figures of exemplary embodiments. However, such exemplary embodiments should not be construed as limitation of the present disclosure. In the figures neither the vehicle nor the complete system for demisting is depicted for the purpose of simplicity. One skilled in the art would appreciate that the system may be employed in any vehicle including but not limiting to passenger vehicles, commercial vehicles including light and heavy duty commercial vehicles, and the like. However, vehicle is not shown in the figures for the purpose of simplicity.

The following paragraphs describe the present disclosure with reference to FIG.1 and FIG.2.

FIG.1 is an exemplary embodiment of the present disclosure, illustrating a block diagram of a system (100) for demisting a windshield in a vehicle. The system (100) broadly includes an air circulating unit (101) and a demisting unit (102). The air circulating unit (101) of the present disclosure may include an air compressor (107). The air compressor (107) may be communicatively coupled to an engine of the vehicle. In an embodiment, the air compressor (107) may be mounted onto the engine of the vehicle. The air compressor (107) may also be mounted onto the side of the engine of the vehicle. The air compressor (107) may be driven by the engine through at least one of a gear drive or a belt drive mechanism. For example, a fan belt drive may be used to drive the air compressor (107). The air compressor (107) may be configured to compress air flowing into the air circulating unit (101). In an embodiment, the air compressor (107) may be such as but not limiting to a piston-type air compressor (107). In addition to the air compressor (107), the air circulating unit (101) also includes a brake system air reservoir (113). The brake system air reservoir (113) is configured to store the air compressed by the air compressor (107) of the air circulating unit (101). The air compressor (107) may direct the compressed air into the brake system air reservoir (113).

Further, the air circulating unit (101) includes a pressure regulator (108) and an air dryer (103) fluidly connected to both the air compressor (107) and the brake system air reservoir (113). The pressure regulator (108) may be configured to control the pressure within the air circulating unit (101). The compressed and regulated air is further passed through the air dryer (103). The air dryer (103) may also be configured to dehumidify the compressed air flowing into the brake system air reservoir (113) from the air compressor (107). In an embodiment, the air circulating unit (101) may include a brake chamber (106) associated with the brake system air reservoir (113). The brake system air reservoir (113) circulates the stored compressed air into the brake chamber (106). In an embodiment, the brake chamber (106) may include a front and rear brake circuit which may be in fluid communication with the brake system air reservoir (113). The front and rear brake circuit may be configured to distribute the compressed air to the front and rear wheels of the vehicle respectively. In an embodiment, a four-way protection valve (120) may be in fluid connection with the front and rear brake circuit. The four-way protection valve (120) may be configured to selectively allow the flow of compressed air to the front and rear brake circuit. The front and rear brake circuit in function is configured to apply pressure over a plurality of brake pads. In an embodiment, the compressed air flowing through the front and rear brake circuits aid in applying pressure over the brake pads of the vehicle. The brake pads of the vehicle in turn aids in decelerating the vehicle or bringing the vehicle to standstill condition.

Further, as shown in FIG.1, the demisting unit (102) may be fluidly connected to the air circulating unit (101) of the system (100). The demisting unit (102) may include a primary valve (105), a reservoir (104), a secondary valve (112), a desiccant chamber (110), demisting vents (109) and a blower unit (111) which may be associated with both the reservoir (104) and the demisting vents (109). In some embodiments, the primary valve (105) may also be referred to as a bypass valve and the secondary valve (112) may be referred to as supply valve. In addition, the demisting unit (102) may be communicatively coupled to a Electronic Control Unit [ECU (114)] in the vehicle. The ECU (114) may be communicatively coupled to the primary valve (105) and the secondary valve (112). The ECU (114) may be configured to selectively operate at least one of the primary valve (105) or the secondary valve (112) to open or closed condition. The primary valve (105) may be fluidly connected to the air circulating unit (101) [best shown in FIG.2]. In an embodiment, the primary valve (105) may be fluidly connected between the brake system air reservoir (113) and the brake chamber (106) of the air circulating unit (101). The primary valve (105) used in the system (100) may be such as but not limiting to a solenoid valve. In an embodiment, the primary valve (105) may be configured to selectively tap the compressed air flowing into the brake chamber (106) of the air circulating unit (101). The compressed air tapped by the primary valve (105) may further be directed to the reservoir (104). One end of the reservoir (104) of the demisting unit (102) may be in fluid communication with the primary valve (105). Likewise, another end of the reservoir (104) may be in fluid communication with the secondary valve (112). The reservoir (104) may be configured to store the compressed air tapped from the air circulating unit (101) through the activation of the primary valve (105). The secondary valve (112) connected to the other end of the reservoir (104) may assist in releasing the compressed air from the reservoir (104). In an embodiment, the secondary valve (112) used in the system (100) may be such as but not limiting to a solenoid valve. Further, the desiccant chamber (110) may be fluidically connected to the secondary valve (112). The desiccant chamber (110) may receive the compressed air released from the reservoir (104) by the secondary valve (112). The desiccant chamber (110) may be configured to absorb the moisture from the compressed air released from the reservoir (104).

The process of absorbing moisture ensures that the compressed air is humid free. Further, to achieve the absorption of the moisture within the desiccant chamber (110), an absorption material may be disposed within the desiccant chamber (110). In an embodiment, the materials disposed within the desiccant chamber (110) may be at least one of a montmorillonite clay, molecular sieve or a pack of silica gel. The desiccant chamber (110) may be further connected fluidly with the demising vents (109) of the vehicle. The desiccant chamber (110) may direct the dehumidified and compressed air onto the windshields of the vehicles via the demisting vents (109). In an embodiment, the demisting vents (109) of the vehicle may be positioned near the windshield. In another embodiment, the demisting vents (109) may also be positioned near the side windows of the vehicle. The compressed and dehumidified air may be directed to the demisting vents (109) to demist the windshield of the vehicle whenever the need for demisting arises. Further, the blower unit (111) may also be provisioned in the demisting unit (102), wherein the blower unit (111) may be in fluid communication with the demisting unit (102). The blower unit (111) may be configured to accelerate the flow of compressed and dehumidified air through the demisting vents (109).

Referring now to FIG.2 in conjunction with FIG.1, which is a flowchart of a method of demisting a windshield in a vehicle.

As illustrated in flowchart of FIG.2, the method includes one or more blocks illustrating a method of demisting the windshield in the vehicle. The method may be described in the general context of computer executable instructions. Generally, computer executable instructions can include routines, programs, objects, components, data structures, procedures, modules, and functions, which perform functions or implement abstract data types.

The order in which the method is described is not intended to be construed as a limitation, and any number of the described method blocks can be combined in any order to implement the method. Additionally, individual blocks may be deleted from the methods without departing from the spirit and scope of the subject matter described herein. Furthermore, the method can be implemented in any suitable hardware, software, firmware, or combination thereof.

As shown in FIG.2, the ECU (114) may be communicatively coupled to the primary valve (105) and the secondary valve (112). In addition, the ECU (114) may also be configured to receive signal from the brake system air reservoir (113) associated with the brake chamber (106) of the air circulating unit (101). As shown at block 115, the ECU (114) may operate the primary valve (105) which is in fluid communication with the air circulating unit (101) to at least one of an open condition or closed condition. In an embodiment, the closed condition of the primary valve (105) may restrict the flow of compressed air from the air circulating unit (101) to the reservoir (104). Further, the open condition of the primary valve (105) may restrict the flow of compressed air into the brake chamber (106) and allow the flow of compressed air into the reservoir (104) of the demisting unit (102). The ECU (114) may be configured to operate the primary valve (105) to open condition when pressure of the compressed air in the brake chamber (106) is at a predetermined limit. On the contrary, if the pressure of compressed air in the brake chamber (106) is less than the predetermined limit, the ECU (114) keeps the primary valve (105) in the closed condition, this ensures that the brake safety is not compromised at any point of time in the system (100) of the present disclosure. In an embodiment, the ECU (114) may be configured to receive a signal from the brake chamber (106), wherein the signal may be generated by the brake chamber (106) when the pressure in the brake chamber (106) drops below the predetermined limit. When the pressure in the brake chamber (106) drops below the predetermined limit, the ECU (114) instantly restricts the flow of air into the demisting unit (102). Once the primary valve (105) is in open condition, the compressed air from the air circulating unit (101) is directed to the demisting unit (102).

Further, as shown at block 116, the air directed into the demisting unit (102) may be stored in the reservoir (104). Furthermore, as shown at 117, the ECU (114) may operate the secondary valve (112) upon receiving a request for demisting of the windshield of the vehicle. In an embodiment, the request for demisting the windshields may be raised by a user of the vehicle when the mist is formed on the wind shields or an automatic demisting signal may be generated in the vehicle. The secondary valve (112) may be operated to an open condition when the request for demisting the windshield is received by the ECU (114). Further, switching the secondary valve (112) to open condition may release the air stored in the reservoir (104). The air stored in the reservoir (104) may be released into the demisting vents (109) [as shown at 118] through the desiccant chamber (110), wherein the desiccant chamber (110) absorbs the moisture from the compressed air. Further, the flow of dehumidified and compressed air is directed onto the windshield to demist the windshield. In an embodiment, the compressed air may be directed into the desiccant chamber (110) before the air is directed into the demisting vents (109). In an embodiment, the ECU (114) may be configured to operate the blower unit (111) upon receiving a request to accelerate the flow of air. The blower unit (111) accelerates the flow of air through the demisting vents (109), thereby aiding in quicker demisting of the windshields.
In an embodiment, the present disclosure discloses a system (100) for demisting a windshield in a vehicle. The system (100) offers advantages, including but not limited to, providing an improved demisting performance in the vehicle. Also, the present disclosure does not necessitate the use of external air source, instead uses the already existing pneumatic air circulating unit (101) of the vehicle. Thereby improving the quality of the demisting system (100). The system (100) improves the time period for clearing of the mist. Also, the system (100) of the present disclosure does not compromise with the safety of the vehicle i.e., the brake line is operated as a priority over the demisting system (102).

It may be noted that, one skilled in the art would modify the configuration of the system (100) for demisting a windshield to suit different vehicles without deviating from scope of the disclosure. Such modifications should be considered as a part of the present disclosure.
