Abstract
Description
TECHNICAL FIELD
[002] The present subject matter described herein, in general, relates to the field of handdrying apparatuses, specifically encompassing advanced sensor technologies, image processing algorithms, and data fusion techniques. Additionally, it integrates innovative features related to hygiene, including touchless activation, antimicrobial coatings, and HEPA filters, alongside energy-efficient components, aligning with environmental sustainability.BACKGROUND
[003] Misuse of automatic hand dryers in public restrooms can lead to various problems and inconveniences. While these machines are designed to promote hygiene and efficiency, they can become a source of frustration and maintenance issues when used improperly. These kinds of misuse can impact various aspects of their operations and facilities.
[004] Generally, when individuals misuse automatic hand dryers, they may engage in disruptive behaviour, such as shouting over the noise generated by the dryer or intentionally triggering it repeatedly for amusement. This behaviour can have several adverse effects on the restroom environment. Firstly, the constant noise pollution caused by shouting or repetitive hand dryer activation can disrupt the peace and quiet that restroom users expect. Restrooms are typically designed as spaces for personal care and brief respite, and excessive noise can be jarring and unpleasant for those seeking a moment of relaxation or privacy. This disruption can lead to discomfort for other users. People enter restrooms with the expectation of a certain level of comfort, cleanliness, and tranquillity. When this expectation is disrupted by loud and unnecessary noise, it can create a negative experience, which may deter individuals from returning to that facility.
[005] The limited moisture detection in conventional hand dryers gives rise to significant issues, most notably extended drying times such as wasted energy as these hand dryers operate for a fixed duration, they often continue blowing hot air even when the user's hands are already dry. This is a considerable waste of energy, as it expands electricity and consumes resources without providing any benefit. Users may complete their hand drying within a few seconds, but the dryer continues running, needlessly heating air and consuming power.Extended drying times can be highly frustrating for restroom users. Having to wait for a hand dryer to finish its cycle when their hands are already dry is not only inconvenient but also annoying. It can lead to negative restroom experiences, leaving users dissatisfied and potentially affecting their perception of the facility as a whole.
[006] Furthermore, conventional hand dryers, often found in restrooms, rely on simplistic operating mechanisms. These mechanisms usually fall into two categories such as the timer-based mechanism which operates for a fixed duration, regardless of the actual moisture content on the user's hands. Some conventional hand dryers require users to push a button to start the drying process and push it again to stop it. Again, there is no real-time moisture detection in this approach. Such hand dryers require physical contact with them which leads to exposure to contagious diseases such as Covid-19 and others. These basic systems do not have sensors or technology to assess the moisture level on a user's hands accurately.
[007] The result of prolonged drying times may drive users to seek alternative drying methods, such as paper towels. This not only defeats the purpose of having hand dryers, which are intended to reduce paper waste but also increases the facility's operational costs as it necessitates more frequent paper towel replenishment and disposal.
[008] Conventional automatic hand dryers rely on motion sensors to function properly. Misuse can involve intentionally covering or obstructing these sensors, rendering the dryer inoperative. This disrupts the flow of users through the restroom and creates a need for maintenance to rectify the issue. These blocked sensors lead to inconvenience for users and higher maintenance expenses for facility managers. Another common misuse is activating hand dryers with wet or soapy hands. Doing so can cause water droplets to scatter around the restroom, potentially spreading germs and creating a less hygienic environment. This misuse undermines the very purpose of hand dryers, which is to improve restroom hygiene by reducing the reliance on paper towels. Some users also inadvertently misuse hand dryers by not placing their hands correctly under the air stream or by moving their hands too quickly. This leads to inefficient drying and can frustrate users. When individuals feel that hand dryers are ineffective, they may resort to alternative drying methods, which are often less ecofriendly and hygienic.
[009] Despite constant efforts to address the issues related to the misuse of automatic hand dryers through technological advancements and user education, some challenges still persist and need to be addressed. While advanced sensors and real-time moisture detection have improved efficiency and reduced energy wastage, sensor obstruction or user errors can still disrupt the drying process.
[0010] Furthermore, despite the implementation of filters for air purification to enhance hygiene, the complete elimination of concerns about germ spread remains a challenge. Users with excessively wet or soapy hands may inadvertently introduce moisture into the restroom environment, even with advanced filtration systems in place. Therefore, it's clear that while technology and education are valuable tools in mitigating the problems associated with hand dryer misuse, achieving a comprehensive solution demands ongoing efforts and a multifaceted approach.
[0011] Therefore, it is very evident to provide the solution by advancing the technology that helps to solve the issues above-discussed problems which develop a noise-free and advanced hair dryer system for drying the hands with the help of precise moisture detection and with the help of object detection under the dryer and also provide a germ-free environment in the restrooms.
[0012] However, the above-mentioned problems have been addressed and tried to technically resolve at various levels but different approaches apart from the above-mentioned alternatives, but the complete solution is not provided yet by any of the measures with the improved and dedicated pointing.

This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiment set forth herein. Rather, the embodiment is provided so that this disclosure is thorough and complete and conveys fully the scope of the invention to those skilled in the art. In the following detailed description, numeric values and ranges are provided for various aspects of the implementations described. These values and ranges are to be treated as examples only and are not intended to limit the scope of the claims. In addition, a number of materials are identified as suitable for various facets of the implementations. These materials are to be treated as exemplary and are not intended to limit the scope of the invention.
[0034] The present invention provides a hand drying apparatus and, more specifically, to a novel and innovative hand dryer equipped with advanced sensor technologies for efficient and hygienic hand drying processes. The apparatus incorporates capacitive sensors, microwave sensors, image processing techniques, and data fusion methodologies to accurately detect the presence of wet hands, thereby optimizing the drying process while maintaining a focus on hygiene and sustainability.
[0035] In one embodiment, the capacitive sensor system serves as a fundamental component responsible for detecting the presence of wet hands without the need for direct physical contact. These capacitive sensors are strategically incorporated into the palm-resting surface of the hand dryer or any other suitable location where users typically place their hands during the drying process.
[0036] In another embodiment, each capacitive sensor comprises two distinct plates in which one is fixed in place within the hand dryer's housing, while the other is designed to be movable. This dual-plate configuration is pivotal in achieving the sensor's primary objective -detecting wet hands with precision and sensitivity. The fixed plate is securely anchored within the hand dryer's structure, ensuring stability and durability. It acts as a reference point for capacitance measurement and remains unaffected by external factors, such as temperature variations or mechanical stress. The movable plate is positioned in close proximity to the fixed plate but is not physically connected to it. This arrangement allows for flexibility in detecting subtle changes in capacitance when a user's hand approaches the sensor.
[0037] In another embodiment, when the user places his / her wet hands in the vicinity of the capacitive sensors, the conduction of water molecules. As the user's wet hand approaches the sensor, the water molecules inherently present on the moist skin establish a conductive path between the two distinct plates comprising the capacitive sensor system. This conductive path formation is an outcome of water's well-known electrical conductivity properties.
[0038] In another embodiment, it is tied to the process, the presence of this conductive path between the sensor plates induces a consequential alteration in the capacitance of the sensor. Capacitance signifies the sensor's intrinsic ability to store electrical charge. Furthermore, the capacitive sensor's functionality depends on the integration of electronic circuits within thehand dryer apparatus. This electronic circuit is meticulously designed and seamlessly integrated into the device's framework.
[0039] In another embodiment, the electronic circuit undertakes the continuous and real-time monitoring of the sensor's capacitance. As the water molecules from the user's wet hands dynamically create and modify the conductive path between the sensor plates, the capacitance exhibits characteristic fluctuations. These minute fluctuations are swiftly and precisely detected by the electronic circuit, and the corresponding data is promptly recorded.
[0040] In another embodiment, the hand dryer is not solely dependent on capacitive sensors for moisture detection. It also incorporates microwave sensors, strategically positioned in close proximity to the drying nozzle. These microwave sensors perform an indispensable function in accurately detecting moisture content on the user's hands throughout the drying process.
[0041] In another embodiment, the microwave sensor system is a sophisticated mechanism designed to interact with the user's hands as they are exposed to the drying process. At the core of this system lies a highly specialized antenna, meticulously engineered for the specific purpose of emitting microwaves toward the user's hands.
[0042] In another embodiment, the interaction between the emitted microwaves and the water molecules present in the user's hands forms the crux of the microwave sensor system's functionality. When a user's hand is wet, the water molecules on the skin's surface possess a heightened reflective capacity compared to dry skin. This discrepancy in reflective behavior is the pivotal signal that the microwave sensors exploit to detect the presence of moisture. As the emitted microwaves encounter wet hands, they undergo a complex interaction with the water molecules. These molecules reflect a greater proportion of the microwaves back towards the sensor system due to their inherent electrical properties. This reflection phenomenon is a direct consequence of the higher moisture content on the user's hands.
[0043] In another embodiment, to interpret the variations in the reflected microwaves, the hand dryer incorporates a specialized electronic circuit. This electronic circuit is adept at signal processing and is meticulously tuned to handle the specific signals generated by the microwave sensor system. As the reflected microwaves return to the sensor system, they carry with them data about the moisture content of the user's hands. The electronic circuitprocesses these microwave signals with precision and efficiency, effectively extracting the relevant data pertaining to moisture levels.
[0044] In another embodiment, the combined operation of the microwave sensors and the electronic circuitry leads to the precise identification of moisture present in the user's hands. By analyzing the variations in reflected microwaves, the microwave sensors can accurately determine the extent of moisture, ensuring that the hand dryer's drying cycle is tailored to the actual moisture level present. The moisture detection process, involving both capacitive and microwave sensors, results in an optimized and efficient drying process. The hand dryer is capable of adjusting the drying cycle duration based on real-time moisture data. When moisture is detected, the drying process continues until the hands are completely dry, conserving energy and time. Conversely, if the sensors determine that the hands are already dry, the dryer shuts off promptly, further enhancing energy efficiency.
[0045] In another embodiment, the integration of microwave sensors complements the capacitive sensors, contributing to the hand dryer's precision and efficiency. The microwave sensors play a pivotal role in accurately detecting moisture content on the user's hands, which, when combined with the data from the capacitive sensors, leads to a highly optimized and efficient drying process, ensuring the best possible user experience.
[0046] In another embodiment, advanced image processing algorithms and data fusion techniques are incorporated. These algorithms are designed to seamlessly process data originating from both the capacitive and microwave sensors in real time. The objective is to create a comprehensive system capable of providing accurate and reliable wet hand detection.
[0047] In another embodiment, the image processing algorithms act as the bridge between the capacitive and microwave sensors, effectively collating data from these two sensor systems. This integration serves as a vital step in improving the overall detection accuracy, as it brings together information from multiple sources.
[0048] In another embodiment, the data fusion techniques in this invention are not merely data aggregation processes; they are intelligently designed to fuse information from the capacitive and microwave sensors in a synergistic manner. By combining the data streams from these sensors, the system achieves a higher level of precision and reliability in determining the moisture level on the user's hands.
[0049] In another embodiment, in addition to image processing and data fusion, the hand dryer is equipped with machine learning algorithms. These algorithms operate continuously, refining the system's ability to distinguish between wet and dry hands. This dynamic approach is rooted in the accumulation of user data and preferences over time.
[0050] In another embodiment, the machine learning algorithms draw from a wealth of data collected during actual usage. This data includes information related to user hand characteristics, drying preferences, and the corresponding sensor responses. This accumulated data serves as a valuable resource for improving the system's understanding of user-specific patterns.
[0051] In another embodiment, the adaptive nature of these algorithms allows the hand dryer to tailor the drying experience to individual preferences. As the system gains insights into specific user behaviors, it fine-tunes the drying cycle to align with user expectations. This personalized approach enhances user satisfaction and overall user experience.
[0052] In another embodiment, the amalgamation of capacitive and microwave sensors, coupled with advanced image processing and data fusion techniques, culminates in an exceptionally efficient drying process. This efficiency revolves around the accurate detection of moisture on the user's hands and the optimization of the drying cycle.
[0053] The hand dryer, informed by the data collected and processed by its sensors and algorithms, optimizes the drying time. It tailors the duration of the drying cycle based on the real-time moisture data it receives. When moisture is detected, the dryer continues operation until the hands are completely dry, thereby eliminating unnecessary drying time and conserving energy.
[0054] By minimizing drying time and ensuring that the dryer operates only when needed, the invention significantly reduces electricity wastage. This not only renders the device an energy-efficient solution but also aligns with sustainability goals, contributing to a greener environment.
[0055] In another embodiment, the hand dryer of the present invention provides user hygiene and convenience by implementing touchless activation through advanced infrared sensor technology. The touchless activation feature eliminates the need for users to physicallyinteract with any part of the device during its operation. In environments such as public restrooms, where hygiene is of paramount importance.
[0056] In this embodiment, these sensors are strategically positioned in areas where users are expected to place their hands during the drying process. What sets these sensors apart is their ability to detect the presence of hands within their proximity by recognizing the infrared radiation naturally emitted by the human body. Upon detecting the approach of a user's hands, the infrared sensors trigger the hand dryer's activation automatically. This touchless operation eliminates the need for any physical contact with potentially contaminated surfaces, significantly reducing the risk of germ transmission.
[0057] In another embodiment, the hand dryer is designed to elevate hygiene standards through a combination of antimicrobial coatings and UV-C sterilization technology. These features work harmoniously to create an exceptionally clean and safe hand-drying option for users, particularly in settings where germ transmission is a concern. The antimicrobial coatings are applied to the surfaces of the hand dryer that frequently come into contact with users. The antimicrobial material is engineered to release antimicrobial agents continuously, creating an environment hostile to the growth and proliferation of bacteria and other harmful microorganisms.
[0058] In another embodiment, UV-C sterilization technology is seamlessly integrated into the hand dryer's design. After each hand drying cycle is completed, the device initiates a brief UV-C sterilization cycle within its interior. UV-C light, renowned for its germicidal properties, is emitted during this cycle, effectively eradicating any remaining microorganisms that may have come into contact with the device during user interaction.
[0059] In another embodiment, the hand dryer's technical advancements are further exemplified by its cost-effective design. The capacitive and microwave sensors, in conjunction with advanced image processing and data fusion techniques, provide a robust yet economical solution. The use of these sensors and algorithms optimizes the drying process, significantly reducing the operating time and energy consumption. This cost-effective operation is achieved without compromising on precision and user experience.
[0060] In another embodiment, the invention is a novel approach by opting for its holistic approach to hand drying. By seamlessly combining capacitive and microwave sensors,advanced image processing, data fusion techniques, and machine learning, the device sets a new standard for hand dryer technology. Its capacity to adapt to user preferences while optimizing energy usage is unparalleled. Furthermore, the incorporation of hygieneenhancing features such as touchless activation, antimicrobial coatings, and HEPA filters represents a novel advancement in hand dryer design. The device's commitment to sustainability by reducing waste from disposable paper towels and minimizing electricity consumption distinguishes it as a pioneering and innovative solution in the field of hand drying apparatuses.
[0061] In an exemplary embodiment, the integration of capacitive and microwave sensors is strategically positioned near the drying nozzle and palm-resting surface. These sensors collectively enable precise moisture detection without physical contact. When a user's wet hands approach the sensor area, water molecules create conductive paths, leading to changes in capacitance and variations in reflected microwaves. The combination of these sensors ensures the hand dryer activates only when wet hands are present, optimizing energy usage and user experience.
[0062] In another exemplary embodiment, state-of-the-art image processing algorithms and data fusion techniques. These algorithms adeptly process data from both the capacitive and microwave sensors in real time. By intelligently amalgamating information from both sensor systems, the accuracy and reliability of wet hand detection are significantly enhanced. Machine learning algorithms continuously refine the system's ability to distinguish between wet and dry hands based on user data and preferences, customizing the drying experience while optimizing energy usage.
[0063] In another embodiment, the above disclosure is a description of the invention and is not intended to limit the scope of the invention. Other variations and modifications of the above-described embodiment shall be apparent to those skilled in the art and are intended to fall within the scope of the invention as defined in the following claims.
