[0001] The present invention relates to a roof ventilation device that is capable of being installed on an opening of a roof for allowing the surrounding air to enter into enclosure for ventilating the enclosure and also capable of adjusting its size in accordance to the weather conditions for allowing only optimum amount of air into the enclosure.

BACKGROUND OF THE INVENTION

[0002] The roof ventilation is crucial for maintaining a healthy and functional home environment. By facilitating the exchange of air between the inside and outside of the house, roof ventilation serves several vital purposes. Firstly, it helps in regulating the indoor temperature by allowing hot air to escape during warmer months, and thereby preventing heat buildup and reducing the strain on air conditioning systems. In colder seasons, proper ventilation helps prevent moisture buildup and condensation, which leads to mold growth and structural damage. Additionally, proper ventilation of home promotes air quality by removing pollutants, allergens, and odors in order to creates a more comfortable and breathable living space. Moreover, it extends the lifespan of roofing materials by minimizing the risk of moisture-related deterioration such as rot and rust. Ultimately, roof ventilation not only enhances the comfort and safety of occupants but also contributes to energy efficiency and the longevity of the building structure, making it an indispensable component of any well-designed property.

[0003] Conventionally roof ventilation are done by installing static vents, ridge vents, gable vents, and turbine vents. The static vents, such as box vents or roof louvers, rely on natural convection to draw hot air out of the attic space. These are expensive, their effectiveness is limited, especially in areas with little wind or during periods of low temperature differentials. While the ridge vents are installed along the peak of the roof in order to provide continuous ventilation along the entire length of the ridge, but they do not provide adequate ventilation, particularly in homes with complex roof designs. Moreover the turbine vents utilizes wind power to draw air out of the attic, but they can be noisy and prone to damage in severe weather conditions.

[0004] US6302778B1 Discloses a turbine roof ventilator includes a rotatable shaft defining an upper end and a lower end. A turbine hood is located on the upper end of the shaft and is adapted to turn with the shaft. A cylindrical sleeve is disposed below the turbine hood. The shaft is mounted in a bearing housing which is fixed relative to the cylindrical sleeve while allowing the shaft to rotate about its longitudinal axis. A fan or vane assembly is disposed on the lower end of the shaft and adapted to turn with the shaft so that as the turbine hood turns, the fan sucks air into the housing to improve the rate of flow of air through the roof ventilator. The cited invention US'778 is kind of ventilator for facilitating the exchange of air between the inside and outside of the house, roof ventilation serves several vital purposes, but it utilizes the wind power to draw in air out of the attic, but they can be noisy and prone to damage in severe weather conditions.

[0005] US7384331B2 discloses about a ridge vent, roof ridge vent installation, and method of installing a ridge vent is provided. Preferably, the ridge vent includes a ventilation material that has opposite longitudinally-extending sides and a longitudinally-extending central section that is transparent. The transparent central section simplifies and enables accurate placement of the vent on the roof ridge. Although the cited invention US'331 is also utilized for ventilation installed along the peak of the roof in order to provide continuous ventilation along the entire length of the ridge, but they do not provide adequate ventilation, particularly in homes with complex roof designs.

[0006] Conventionally, many devices has been developed which are being utilized for the purpose of the roof ventilation, but these all have several limitations with respect to the weather conditions and location. further no such device have been developed that are capable of facilitating the exchange of air between the inside and outside of the house, roof ventilation serves several vital purposes, in every weather conditions. Also no such devices have been developed that are capable of restricting foreign particle from entering into the house for maintaining a healthy and clean environment in the house.

[0007] In order to overcome the aforementioned drawbacks, there exists a need in the art to develop a device that is capable of facilitating the exchange of air between the inside and outside of the house, roof ventilation serves several vital purposes in every season and also there exists the need in the art to develop a device that is capable of preventing the foreign particles from entering into enclosure.

[0017] The following description includes the preferred best mode of one embodiment of the present invention. It will be clear from this description of the invention that the invention is not limited to these illustrated embodiments but that the invention also includes a variety of modifications and embodiments thereto. Therefore, the present description should be seen as illustrative and not limiting.

[0018] In any embodiment described herein, the open-ended terms "comprising," "comprises," and the like (which are synonymous with "including," "having" and "characterized by") may be replaced by the respective partially closed phrases "consisting essentially of," consists essentially of," and the like or the respective closed phrases "consisting of," "consists of, the like.

[0019] As used herein, the singular forms "a," "an," and "the" designate both the singular and the plural, unless expressly stated to designate the singular only.

[0020] The present invention relates to a roof ventilation device that is mounted over a roof's aperture for allowing the fresh air to enter into the enclosure for ventilation and according to the weather the device adjusts its size to let in the optimum amount of air for ventilation.

[0021] Referring to Figure 1 and figure 2, a side view of the a roof ventilation device and an isometric view of proposed device are illustrated, respectively comprising an oval-shaped base frame 101, constructed of multiple telescopically operated curved plates 201, multiple suction units 102 provided underneath the base frame 101, an artificial intelligence based imaging unit 103 configured with the frame 101, a motorized hinge 202 integrated in between each of consecutive plates 201, a cylindrical member 104 installed on the base frame 101 and configured with a meshed sheet 203, and a canopy 105 installed on the member 104 by means of a telescopically operated rod 106.

[0022] The proposed device comprises of an oval-shaped base frame 101 positioned on an opening which has been carved on a roof of an enclosure. The frame 101 is developed a protective exterior of the device and the components associated with the device are mounted over the frame 101. The frame 101 is preferably rectangular in shape and made up of stainless steel that offers a corrosion resistant, strength and durability to the device and is easy to maintain. The frame 101 is constructed of multiple telescopically operated curved plates 201 and under each plates 201 is attached with a suction unit 102 for adhering the frame 101 on the roof.

[0023] Each of the suction units 102 are combinely connected to a vacuum pump which creates the negative pressure within each suction units 102. The vacuum pump comprises of an impeller configured with multiple vanes and which is directly coupled with the shaft of a motor to rotate the impeller. Further, the motor is capable of converting current into mechanical work by following the principle of Lorentz Law which states that, the current carrying conduction when placed in magnetic or electrical field experiences a force known as Lorentz force. Such that the motor converts the electrical current derived from an external source into a mechanical torque for providing the required rotational power to the impeller. The impeller vanes are designed in such a way that on rotation the impeller creates the negative pressure in the units and that results in adhering of the plates 201 with the roof for mounting the frame 101 over the opening in a secured manner.

[0024] Initially, an artificial intelligence based imaging unit 103 which is configured with the frame 101 determines a shape, elevation/depression and curves of the roof. The imaging unit 103 comprises of a processor and a camera which on actuation capture the multiple image of the surroundings. The camera is comprised of a lens and a digital camera sensor, wherein the camera lens takes all the light rays rebounding around the surroundings and utilizes the lenses to transmit them to a single point for creating a sharp image. When all of those light rays rebound back and meet together on a digital camera sensor, create a digital image of the surroundings by performing various operations like pre-processing, feature extraction and classification which is transmitted to the processor.

[0025] The processor further extracts all the required information from the digital images and transmit to an inbuilt microcontroller associated with the device, which further processes the information shared by the processor in order to detect shape, elevation/depression and curves of the roof. Based on the determined shape, elevation/depression and curves of the roof, the microcontroller actuates a motorized hinge 202 integrated in between each of consecutive plates 201 for orienting the frame 101 in accordance to the shape, elevation/depression and curves of the roof, for securely mounting the base frame 101 on the roof.

[0026] The motorized hinges 202 are a piece of metal that interconnects each of consecutive plates 201 for orienting the frame 101 together and allows them to be oriented by revolving along the longitudinal axis whose operation is governed by a bi-directional direct current motor that is linked with the microcontroller. The bi-directional direct current motor is capable of converting direct current into mechanical work by following the principle of Lorentz Law which states that, the current carrying conduction when placed in magnetic or electrical field experiences a force known as Lorentz force. Such that the motor converts the electrical current derived from an external source into a mechanical torque for providing the required power to the hinges 202 to orient the plates 201. When the motor rotates, then provides movement to the hinge 202 followed by which the plates 201 also rotates in to be oriented as per the shape, elevation/depression and curves of the roof for securely mounting the base frame 101 on the roof.

[0027] Further, a cylindrical member 104 is installed on the base frame 101 and configured with a meshed sheet 203 for allowing the air to pass for doing the ventilation in the enclosure. The member 104 is further installed with a weather monitoring sensing module for monitoring weather conditions in the surrounding. The weather monitoring sensing module comprises of a humidity sensor, an anemometer, a rain sensor, and LDR(light and detection ranging) sensor for detecting temperature, humidity, wind speed, rain and light intensity respectively in the surrounding.

[0028] The humidity sensor used herein is preferably a capacitive humidity sensor which rely on changes in the dielectric properties of a material in response to humidity variations. The sensor consists of a humidity-sensitive material sandwiched between two electrodes that has the ability to absorb or adsorb moisture from the surrounding air. When the humidity level increases, the material absorbs water molecules, and its dielectric constant changes. The changes in the dielectric constant of the humidity-sensitive material affects the capacitance between the two electrodes. As moisture is absorbed, the capacitance increases and when released, the capacitance decreases. The capacitive humidity sensor is connected with a sensing circuit that measure the capacitance between the electrodes. The sensing circuit includes an oscillator that generates an alternating current (AC) signal, and the capacitive humidity sensor acts as a part of the capacitive sensing element. The sensing circuit analyzes the capacitance variation and converts into a measurable output, which is either a frequency or a voltage signal. The output is proportional to the humidity level, allowing for the measurement and monitoring of humidity value, which is further sent to the microcontroller. The microcontroller upon receiving and processing the signal received from the humidity sensor to determine humidity value in surrounding air.

[0029] The anemometer consists of multiple cups fabricated around a vertical shaft and a small dynamo coupled with the shaft and these are embodied in a casing. The wind causes the vertical shaft to turn due to wind pressure over the cups and turning of the shaft cause the flow of current across the dynamo which is detected by an inbuilt microcontroller to determine the wind speed and direction. Further the rain sensor used herein works as a switch. The rain sensor consists of an electrically active surface and a circuit linked with the microcontroller. Whenever raindrops fall over the surface, there exists in the fluctuation in the voltage across the circuit due to decreasing in the resistance of the surface and that is detected by the microcontroller.

[0030] Lastly the resistance of the resistor decreases as the light intensity increases. In the dark and at low light levels, the resistance of the LDR is high and little voltage flow through the resistor. And in case of bright light, the resistance is high and low voltage flows across the resistor that is detected by the microcontroller. Further based on the output signal received each sensors, the microcontroller determines weather condition in the surrounding. If the determined weather condition corresponds to hot weather, then the microcontroller actuates an expandable and retractable pulley arrangement to increase size of the cylindrical member 104 for allowing passage of an optimum amount of air via the sheet 203 for ventilating the enclosure.

[0031] The expandable and retractable pulley arrangement comprises of a pulley cut into multiple segments and each attached with center by means of an arm, a motorized gear which is meshed with a toothed wheel, the wheels is carved with multiple slot, plurality of studs in the arms of the pulley. After getting actuation signal from the microcontroller, the motor of the motorized gear rotates it which rotates wheel in clock as well as in counter clockwise direction. Due to rotation of the wheel, the slots thrusts the studs of the arms of the pulley outward and inwards, thus increasing and decreasing the diameter of the pulley for increasing the size of the member 104 for allowing passage of an optimum amount of air via the sheet 203 for ventilating the enclosure.

[0032] Further if the determined weather condition corresponds to a cold weather condition, then the microcontroller directs the arrangement to retract the member 104 to allow minimal air to pass for ventilating the enclosure and also maintaining optimum temperature of the enclosure. Also if the determined weather condition corresponds to a rainy weather condition, then the arrangement adjusts the size of the member 104 to an moderate level to allow passage of suitable amount of the air for ventilation. Further, if the determined weather condition corresponds to a storm, then the microcontroller directs a pressure sensor which is integrated in suction units 102 for determine the pressure applied on the roof. The pressure sensor consists of a measuring coil which measures the strain generated due to pressure applied and converts the measured strain into electrical pulse. Further the microcontroller processes the electric pulse in order to detect the amplitude of the pulse in order to detect the pressure applied by suction units 102 on the roof.

[0033] If the determined pressure is determined to be receding a threshold value, then the microcontroller actuates regulates the functioning of the suctions units to generate more negative pressure to prevent the frame 101 from blowing off during the storm. Also a canopy 105 is installed on the member 104 by means of a telescopically operated rod 106, for preventing the foreign particle from entering into the enclosure during the storm or rainy season. Based on the determined weather condition, the microcontroller actuates the rod 106 to alter the height of the rod 106 which results in adjustment of the canopy 105 in appropriate orientation for preventing the foreign particle from entering into the enclosure.

[0034] The extension/retraction of the rod 106 is powered by a pneumatic unit associated with the device and comprises of an air compressor, air valves, and a piston. The air compressor used herein extract the air from surrounding and increases the pressure of the air by reducing the volume of the air. The air compressor is consist of two main parts including a motor and a pump. The motor powers the compressor pump which uses the energy from the motor drive to draw in atmospheric air and compress to elevated pressure.

[0035] The compressed air is then sent through a discharge tube into the cylinder across the valve. The compressed air in the cylinder tends to pushes out the piston to extend which extends the rod 106. Similarly on evacuating of the compressed air from the cylinder results in retraction of the piston which results in retraction of the rod 106, thereby resulting in altering of the height of the canopy 105 as per weather condition in the surrounding for preventing the foreign particle from entering into the enclosure.

[0036] A battery is associated with the device to supply power to electrically powered components which are employed herein. The battery is comprised of a pair of electrode named as a cathode and an anode. The battery use a chemical reaction of oxidation/reduction to do work on charge and produce a voltage between their anode and cathode and thus produces electrical energy that is used to do work in the device.

[0037] The present invention works well in the following manner where the oval-shaped base frame 101 positioned on the opening which has been carved on a roof of an enclosure. The frame 101 is constructed of multiple telescopically operated curved plates 201 and under each plates 201 is attached with suction unit 102 for adhering the frame 101 on the roof. Initially, the artificial intelligence based imaging unit 103 determines a shape, elevation/depression and curves of the roof and based on the determined shape, elevation/depression and curves of the roof, the microcontroller actuates the motorized hinge 202 for orienting the frame 101 in accordance to the shape, elevation/depression and curves of the roof, for securely mounting the base frame 101 on the roof for securely mounting the base frame 101 on the roof. Further the weather monitoring sensing module monitors weather conditions in the surrounding and if the determined weather condition corresponds to hot weather, then the microcontroller actuates expandable and retractable pulley arrangement to increase size of the cylindrical member 104 for allowing passage of an optimum amount of air via the sheet 203 for ventilating the enclosure. Further if the determined weather condition corresponds to a cold weather condition, then the microcontroller directs the arrangement to retract the member 104 to allow minimal air to pass for ventilating the enclosure and also maintaining optimum temperature of the enclosure. Also if the determined weather condition corresponds to a rainy weather condition, then the arrangement adjusts the size of the member 104 to an moderate level to allow passage of suitable amount of the air for ventilation. Further, if the determined weather condition corresponds to a storm, then the microcontroller directs pressure sensor for determine the pressure applied on the roof. If the determined pressure is determined to be receding a threshold value, then the microcontroller regulates the functioning of the suctions units to generate more negative pressure to prevent the frame 101 from blowing off during the storm. Also canopy 105 is installed on the member 104 for preventing the foreign particle from entering into the enclosure during the storm or rainy season.
