Description

TECHNICAL FIELD

[0001] The present invention relates to an outdoor cooling system for shaded seating areas. The system comprises a canopy mounted above a table, a cooling unit disposed on top of the canopy, a set of adjustable air vents disposed beneath the canopy, and a water circulation mechanism for enabling evaporative cooling.BACKGROUND

[0002] Outdoor cooling systems for shaded seating are often deployed in parks, resorts, cafés, and other outdoor environments where heat mitigation is essential for comfort. Traditional approaches range from misting umbrellas to evaporative air units, yet these systems frequently suffer from structural limitations, inefficient cooling methods, or operational complexity. While various designs have emerged to improve outdoor comfort, many of these systems fail to provide integrated, self-contained solutions that balance portability, performance, and control.

[0003] Chinese Utility Model CN207912250U discloses an umbrella structure incorporating an evaporative cooling mechanism. The system features a cloth canopy with a water-absorbent inner layer and includes a fan and spray mechanism to distribute cool air. However, the design lacks any integrated structure for seated usage or any defined placement of the water tank and pump system. Additionally, it does not include electronically adjustable airflow, air vent directionality, or intelligent operational control, which limits its cooling efficiency and adaptability in varied outdoor scenarios.

[0004] U.S. Pat. No. 6,886,759B1 describes a water misting umbrella that utilizes a network of spray nozzles integrated into the umbrella canopy. This design allows mist to be delivered using an external pressurized water source, providing relief in hot environments. Nonetheless, it does not feature any fan-assisted air movement, internal water storage, or pumping components. The system also lacks self-sufficiency, requiring continuous connection to external plumbing, and offers no electronic controls or integration for temperature regulation.

[0005] United States Patent Application US20120103376A1 outlines a free-standing umbrella equipped with a misting system capable of atomizing water droplets under the canopy. The system includes a spray manifold and a control mechanism for regulating mist based on ambient air temperature. Despite these enhancements, the invention is reliant on misting alone for cooling and does not incorporate airflow components such as fans or motors. It also lacks a recirculating water system, and does not provide electronic or programmable control through a centralized logic unit.

[0006] Chinese Patent Application CN110786606A describes an outdoor umbrella air conditioning device that includes a control system and dual canopy surfaces. The device uses sensors to detect human presence and ambient conditions and powers an internal air conditioning unit accordingly. While this system addresses some automation aspects, it relies on a chassis-mounted battery-powered AC compressor, which increases complexity and weight. Furthermore, it lacks an evaporative cooling mechanism with a recirculating water loop, omits directional vent control, and does not provide for lightweight construction suited to portable shaded seating use cases.

[0007] It will be appreciated that while the above systems contribute incrementally to outdoor cooling, each suffers from notable limitations. Some require external infrastructure, such as pressurized water or electrical outlets. Others do not include airflow modulation through fans or directional vents, while several lack closed-loop water circulation or programmable control systems. These deficiencies hinder their effectiveness, usability, and deployment in public or commercial spaces where efficient, self-contained, and controllable cooling is necessary.SUMMARY

[0008] The present disclosure provides a canopy-based outdoor cooling system. The system comprises a canopy mounted above a table and a cooling unit disposed on top of the canopy. The cooling unit comprises a fan and a motor connected to the fan, wherein the fan is configured to generate airflow. A plurality of air vents is disposed underneath the canopy, each vent being operatively connected to the cooling unit and angularly adjustable within a range of 30 to 90 degrees to direct cooled air downward toward the table. The system further comprises a water tank positioned beneath the table for storing water, a pump connected to the water tank and a lifting pipe for delivering water from the tank to the cooling unit, and a return pipe configured to return excess or condensed water from the cooling unit to the water tank. A printed circuit board (PCB) is connected to both the motor and the pump and is configured to control their operation for consistent and effective delivery of cool air through the air vents. This configuration facilitates targeted and recirculated evaporative cooling in outdoor seating environments while maintaining a self-contained and electronically coordinated structure.

[0009] In one implementation form, the cooling unit comprises an enclosure fabricated from ultraviolet light-resistant plastic or lightweight and durable aluminum. This material configuration improves weather resistance while maintaining structural integrity and portability.

[0010] In another implementation form, the cooling unit further comprises an automatic drain valve connected to the return pipe, the automatic drain valve being configured to discharge excess or condensed water from the cooling unit into the water tank. This allows for uninterrupted operation while reducing the risk of water accumulation or overflow.

[0011] In another implementation form, the cooling unit further comprises a dust filter positioned to filter dust from air entering the cooling unit. This helps improve air quality and prevent contamination of internal components.

[0012] In a further implementation form, the cooling unit further comprises a cellulose pad configured to retain water, wherein the cellulose pad facilitates evaporative cooling of air passing through the pad. This design enhances cooling efficiency by leveraging evaporative principles within the airflow stream.

[0013] In one implementation form, the cooling unit further comprises a water distributor configured to distribute water received from the lifting pipe across the cellulose pad. This ensures uniform saturation of the cellulose pad and optimizes the evaporation surface area.

[0014] In another implementation form, the cooling unit further comprises a water collection basin configured to collect excess water flowing through the cellulose pad. This supports a closed-loop water circulation system and helps minimize water waste.

[0015] In yet another implementation form, the cellulose pad is fabricated from treated, mold-resistant compressed cardboard or cellulose paper. This improves durability and hygiene while maintaining efficient moisture retention.

[0016] In one implementation form, each of the air vents is disposed at a downward angle of 60 degrees relative to the canopy. This orientation provides efficient and directed airflow to users seated around the table.

[0017] In another implementation form, the fan comprises blades fabricated from reinforced plastic or light aluminum. This construction offers a balance between weight reduction and structural performance.

[0018] In a further implementation form, the motor comprises copper coils or aluminum coils, a stainless steel casing, and a thermoplastic housing. These features enable reliable motor function under varying environmental conditions.

[0019] In another implementation form, the pump is disposed within a pump housing fabricated from water-resistant reinforced plastic. This design protects pump components from environmental damage and extends service life.

[0020] In a further implementation form, the pump is connected to a pump motor comprising copper coils or aluminum coils. This allows for efficient electrical operation while offering material flexibility based on manufacturing preferences.

[0021] In another implementation form, each of the lifting pipe and the return pipe is fabricated from reinforced plastic or stainless steel. These materials provide mechanical strength and corrosion resistance for the water transport channels.

[0022] In one implementation form, the PCB is disposed outside the cooling unit. This placement protects sensitive electronics from water exposure and improves maintainability.

[0023] In another implementation form, the PCB is communicatively connected to a control system comprising a wall-mounted control unit and a remote control. This enables wireless user interaction and allows flexible control over cooling system functions from a distance.

[0032] The example embodiments herein and the various features and advantageous details thereof are explained more fully with reference to the non-limiting embodiments that are illustrated in the accompanying drawings and detailed in the following description. Descriptions of well-known components and processing techniques are omitted to not unnecessarily obscure the embodiments herein. The description herein is intended merely to facilitate an understanding of ways in which the example embodiments herein can be practiced and to further enable those of skill in the art to practice the example embodiments herein. Accordingly, this disclosure should not be construed as limiting the scope of the example embodiments herein.

[0033] Referring to FIG. 1, there is shown a perspective view of a canopy-based outdoor cooling system 100, in accordance with an embodiment of the present disclosure. The system 100 is designed to deliver evaporative cooling to individuals seated around a table in outdoor environments, such as cafés, public parks, and resorts, by integrating a canopy structure, a cooling unit, and a closed-loop water circulation mechanism. The system 100 combines passive shading with active cooling, thereby improving thermal comfort in open-air settings.

[0034] The system 100 comprises a canopy 102 mounted above a table 104. The term “canopy” as used herein relates to a broad, overhead cover configured to provide shade and structural support for associated components. In the present example, the canopy 102 is configured to support the weight of an elevated cooling unit while also functioning as a platform for distributing cooled air. The canopy 102 is mounted at a height sufficient to allow individuals to be seated comfortably underneath, while maintaining an unobstructed flow of air from the cooling system.

[0035] The system 100 further comprises a cooling unit 106 disposed on top of the canopy 102. The term “cooling unit” as used herein refers to an air-cooling apparatus configured to generate and deliver cooled air downward toward the seating area. The elevated placement of the cooling unit 106 allows gravitational air distribution and facilitates vertical separation from the water tank below. In one example, the cooling unit 106 is implemented as a desert air conditioning module and is compact in form to minimize structural load on the canopy 102. This placement also enables air to flow directly downward with minimal resistance.

[0036] The cooling unit 106 comprises a motor 108 operatively connected to a fan (not shown in the figure) configured to generate airflow. The term “motor” as used herein refers to an electric driving component configured to rotate the fan blades within the cooling unit 106. Upon activation, the motor 108 drives the fan to create a consistent suction of ambient air into the cooling unit and subsequently force the air through the internal cooling components, allowing the expulsion of cooled air toward the target area.

[0037] The system 100 further comprises a plurality of air vents 110 disposed underneath the canopy 102. The term “air vent” as used herein relates to an outlet configured to direct and discharge cooled air toward a designated area. Each air vent 110 is fluidly connected to the cooling unit 106 and is angularly adjustable within a range of 30 to 90 degrees relative to the horizontal plane of the canopy 102. This configuration allows the user to control the direction of airflow depending on sun orientation, wind conditions, and user seating arrangements. In one preferred implementation, the vents are set at a 60-degree angle to maximize downward air coverage across the entire table area.

[0038] The system 100 additionally comprises a water tank 112 positioned beneath the table 104. The term “water tank” as used herein refers to a sealed container configured to store water required for evaporative cooling. The tank 112 is positioned centrally and low to the ground to serve as a stable base for the vertical support structure. Its placement directly below the table also enables compact integration of the seating, shading, and cooling components into one unified system.

[0039] A lifting pipe 114 extends from the water tank 112 to the cooling unit 106. The term “lifting pipe” as used herein relates to a fluid conduit configured to carry water upward from the tank to the elevated cooling unit. The lifting pipe 114 is vertically mounted within the central column supporting the canopy and allows continuous water delivery to the cooling unit during system operation. Because the cooling unit is elevated, the water lifted through this pipe experiences incidental cooling as it passes through ambient airflow channels surrounding the column.

[0040] A return pipe 116 extends from the cooling unit 106 back to the water tank 112. The term “return pipe” as used herein refers to a conduit configured to transport excess or condensed water from the cooling unit downward into the water tank for recirculation. This return path ensures closed-loop operation, allowing reuse of the same water and thereby reducing consumption. As the returning water passes through the ambient zone around the canopy column, it is further cooled, which improves the thermal performance of subsequent cooling cycles.

[0041] The system 100 further comprises a pump 118 connected to the water tank 112 and the lifting pipe 114. The term “pump” as used herein relates to a motor-driven hydraulic device configured to pressurize and transport water from a reservoir to a desired elevation. The pump 118 draws water from the tank and forces it upward through the lifting pipe 114 into the cooling unit 106. The pump 118 may be actuated by an external control system or by the internal logic of the system's PCB.

[0042] A printed circuit board (PCB) 120 is connected to each of the motor 108 and the pump 118. The term “PCB” as used herein refers to a control board embedded with circuit traces and electronic components configured to coordinate and manage the operation of active system elements. The PCB 120 issues electrical signals to initiate the motor for airflow generation and activate the pump for water transfer. In some cases, the PCB may also regulate operating cycles, detect input conditions (e.g., temperature or user command), and shut down the system after a predefined cooling interval. Placement of the PCB 120 outside the cooling unit 106 helps to protect sensitive electronics from moisture exposure and heat accumulation.

[0043] During operation, the PCB 120 activates the pump 118, causing water to be drawn from the tank 112 and lifted through pipe 114 to the cooling unit 106. Inside the cooling unit 106, the water interacts with internal components to cool the incoming airflow. The motor 108 drives the fan to pull ambient air into the unit, which is cooled by water-enhanced evaporative means before being discharged through the air vents 110 toward individuals seated at the table. Excess water is directed back into the tank 112 through the return pipe 116, enabling continuous operation in a closed-loop cycle.

[0044] In one scenario, the system 100 is deployed at a coastal café where guests are seated at outdoor tables during peak afternoon heat. Upon activation, the PCB 120 initiates the motor 108 and pump 118, enabling cool air to flow through the air vents 110. The 60-degree angle of the vents ensures even coverage across the round table, enhancing customer comfort without excessive noise or mist.

[0045] In another scenario, the system 100 is used during a public outdoor event in a park. The cooling unit 106 is started in the morning and continues operation throughout the day. The pump 118 recirculates water efficiently, while the PCB 120 manages operating cycles to balance performance and energy consumption. The return pipe 116 ensures minimal water loss, allowing uninterrupted use over several hours with only a small water reservoir.

[0046] This configuration of the system 100 offers several notable technical advantages. By placing the cooling unit above the canopy, gravitational airflow is harnessed for efficient air distribution without relying on high-powered fans. The integration of a water lifting and return mechanism facilitates closed-loop cooling, which enhances sustainability by minimizing water waste. The angular adjustability of the air vents allows targeted airflow for different user setups, while the use of a PCB enables automated control of pump and motor operations for reliable and responsive cooling. Together, these features create a self-contained and adaptable cooling system suited to a variety of outdoor environments.

[0047] In one implementation form, the cooling unit 106 comprises an enclosure 122, wherein the enclosure 122 is fabricated from ultraviolet light-resistant plastic or lightweight and durable aluminum. The term “enclosure” as used herein refers to the structural housing that surrounds and protects internal cooling components, including the motor 108, fan, and evaporative elements. The enclosure 122 not only provides a physical barrier against dust, debris, and mechanical damage but also ensures thermal insulation and resistance to prolonged sun exposure. Use of UV-resistant or lightweight aluminum materials supports durability in outdoor environments while minimizing structural load on the canopy 102.

[0048] In another implementation form, the cooling unit 106 further comprises an automatic drain valve 124 connected to the return pipe 116. The term “automatic drain valve” as used herein relates to a self-actuating flow control device configured to discharge excess or condensed water from the cooling unit 106 back into the water tank 112 without requiring manual intervention. The drain valve 124 ensures that internal condensation or overflow is efficiently routed into the return pipe 116, preserving the closed-loop nature of the system and preventing accumulation of stagnant water within the cooling unit 106. The automated nature of the valve enables continuous, maintenance-free operation over extended periods.

[0049] In yet another implementation form, the cooling unit 106 further comprises a dust filter 126 positioned to filter dust from air entering the cooling unit 106. The term “dust filter” as used herein refers to a porous or mesh barrier configured to remove airborne particulates from the incoming airflow before it interacts with internal cooling components. The dust filter 126 is preferably mounted at an air intake opening of the cooling unit 106 to preserve the cleanliness and performance of the fan, motor 108, and other cooling media. By preventing particulate buildup, the dust filter 126 enhances airflow quality, prolongs system life, and maintains cooling efficiency, particularly in outdoor environments prone to dust and debris.

[0050] In one implementation form, the cooling unit 106 further comprises a cellulose pad 128 configured to retain water, wherein the cellulose pad 128 facilitates evaporative cooling of air passing through the cellulose pad. The term “cellulose pad” as used herein refers to a porous and moisture-absorbent medium typically fabricated from compressed cellulose or fiberboard, structured to maximize surface area for evaporative exchange. During operation, water lifted from the tank 112 via the lifting pipe 114 is distributed across the cellulose pad 128, which absorbs and retains the moisture. As the motor 108 drives airflow through the saturated pad, heat is extracted from the air via evaporation, lowering its temperature before discharge through the air vents 110. The cellulose pad 128 plays a critical role in the evaporative cooling process by serving as the primary interface between the water and the moving airstream.

[0051] In another implementation form, the cooling unit 106 further comprises a water distributor 130 configured to distribute water received from the lifting pipe 114 across the cellulose pad 128. The term “water distributor” as used herein refers to a fluid delivery mechanism, such as a channel, manifold, or series of perforated nozzles, arranged to ensure uniform dispersion of water over the surface of the cellulose pad 128. The water distributor 130 is positioned at the upper edge of the pad and is configured to minimize oversaturation or dry zones by maintaining even coverage. Uniform distribution of water enhances evaporative efficiency and prevents material degradation caused by uneven moisture loading.

[0052] In yet another implementation form, the cooling unit 106 further comprises a water collection basin 132 configured to collect excess water flowing through the cellulose pad 128. The term “water collection basin” as used herein refers to a lower catchment chamber positioned beneath the cellulose pad 128, designed to collect gravitational runoff from the pad's surface. The water collection basin 132 serves as an intermediary reservoir that channels the collected water into the return pipe 116 for recirculation back to the tank 112. This feature supports water conservation, reduces wastage, and maintains the integrity of the closed-loop system during extended use.

[0053] In one implementation form, the cellulose pad 128 is fabricated from treated, mold-resistant compressed cardboard or cellulose paper. The term “treated, mold-resistant compressed cardboard or cellulose paper” as used herein refers to a class of engineered fibrous materials that have been chemically or structurally enhanced to resist microbial growth and degradation due to constant moisture exposure. This construction ensures that the cellulose pad 128 maintains its structural integrity and cooling efficiency over repeated use cycles. By using materials specifically treated to resist mold and mildew, the system 100 is better suited for long-term operation in humid environments without frequent maintenance or replacement of the cooling media.

[0054] In another implementation form, each of the air vents 110 is disposed at a downward angle of 60 degrees relative to the canopy 102. This specific angular orientation allows cooled air to be projected directly toward individuals seated at the table 104 while minimizing lateral airflow loss. A 60-degree vent angle optimizes air coverage for circular or semi-circular seating arrangements and ensures uniform temperature reduction across the shaded area. This angular configuration is particularly effective in outdoor conditions where directional airflow can be influenced by ambient wind.

[0055] In yet another implementation form, the fan (not shown) comprises blades fabricated from reinforced plastic or light aluminum. The term “reinforced plastic” as used herein refers to polymeric materials strengthened with glass fibers or similar additives to improve mechanical durability, while “light aluminum” refers to low-mass aluminum alloys with sufficient strength-to-weight ratios for efficient rotation. The lightweight nature of both materials minimizes motor load, reduces energy consumption, and improves rotational speed for generating consistent airflow through the cooling unit 106. This enhances the overall cooling performance of the system 100 while maintaining structural simplicity and material longevity.

[0056] In one implementation form, the motor 108 comprises copper coils or aluminum coils, a stainless steel casing, and a thermoplastic housing. The term “copper coils or aluminum coils” as used herein refers to the internal windings of the motor that generate magnetic fields to drive the fan. Copper provides high conductivity and efficiency, while aluminum offers cost and weight advantages. The stainless steel casing functions as a protective outer shell that resists corrosion and mechanical stress during outdoor operation. The thermoplastic housing serves as an insulating and structural enclosure for internal components. This combination of materials ensures durability, weather resistance, and consistent electrical performance under prolonged use.

[0057] In another implementation form, the pump 118 is disposed within a pump housing fabricated from water-resistant reinforced plastic. The term “pump housing” as used herein refers to the structural shell that encloses and protects the pump 118 from external moisture, dust, and impact. The pump housing is designed to operate in a humid or splash-prone environment, particularly given its proximity to the water tank 112. Fabrication from reinforced plastic improves structural stability and resistance to degradation over time, especially in outdoor or semi-permanent installations.

[0058] In yet another implementation form, the pump 118 is connected to a pump motor, wherein the pump motor comprises copper coils or aluminum coils. The term “pump motor” as used herein refers to the dedicated electric drive component that powers the pump 118 to lift water from the tank 112 to the cooling unit 106 via the lifting pipe 114. By using copper or aluminum coils, the pump motor ensures efficient energy transfer and maintains consistent hydraulic performance. The ability to select between copper and aluminum materials allows for design flexibility based on cost, availability, and thermal management requirements.

[0059] In one implementation form, each of the lifting pipe 114 and the return pipe 116 is fabricated from reinforced plastic or stainless steel. The term “reinforced plastic” as used herein refers to polymer materials strengthened with additives such as fiberglass to enhance tensile strength and durability. Stainless steel, on the other hand, provides corrosion resistance and long-term structural reliability. The use of these materials ensures that both the lifting pipe 114 and the return pipe 116 withstand continuous exposure to water flow, pressure fluctuations, and environmental elements during extended outdoor use. This enhances the overall longevity and maintenance-free operation of the water circulation system.

[0060] In another implementation form, the PCB 120 is disposed outside the cooling unit 106. This spatial separation is designed to minimize exposure of the PCB 120 to internal humidity and thermal buildup within the cooling unit. By isolating the PCB 120 from the evaporative zone, the system ensures that electronic control functions remain stable and unaffected by condensation, temperature variation, or splash risk. Placement outside the cooling unit also allows easier access for servicing, firmware updates, or external wiring integration without disassembling primary cooling components.

[0061] In yet another implementation form, the PCB 120 is communicatively connected to a control system comprising a wall-mounted control unit 134 and a remote control 136. The term “control system” as used herein refers to a combination of user interface devices that enable wireless or wired input to the PCB 120 for activating or configuring the operation of the motor 108 and pump 118. The wall-mounted control unit 134 may be installed near the seating area and used for regular operation by on-site personnel, while the remote control 136 allows for convenient activation or adjustment from a distance. This configuration supports flexible and intuitive control, making the system suitable for dynamic outdoor environments where manual access to the core electronics may be limited.

[0062] Referring to FIG. 2, there is shown a perspective view of a water channel 200 (such as the water channel of the canopy-based outdoor cooling system 100 shown in FIG. 1), in accordance with an embodiment of the present disclosure. As shown, the water channel 200 comprises a lifting pipe 202 (such as the lifting pipe 114 of FIG. 1) and a return pipe 204 (such as the return pipe 116 of FIG. 1), configured to transport water from a water tank to a cooling unit positioned above a canopy and back again.

[0063] In one example, the lifting pipe 202 has a length selected from a range of 1.5 to 3 meters, an outer diameter ranging from 10 to 20 centimeters, and a wall thickness ranging from 3 to 8 millimeters. These dimensions are selected based on the required elevation height and water flow rate for efficient cooling. A wider pipe diameter may be selected in scenarios where a higher volume of water is to be delivered to the cooling unit for rapid saturation of the cooling media, thereby improving thermal response in high-demand environments.

[0064] In another scenario, the lifting pipe 202 and return pipe 204 are implemented with varying cross-sectional geometry along their vertical length. For example, either pipe may taper toward its terminal end to increase water velocity or incorporate internal baffles to promote turbulent flow, thereby aiding pre-cooling of the water through enhanced ambient heat exchange during transit.

[0065] In yet another implementation form, one or both of the pipes 202 and 204 may be configured with a helical or coiled profile wrapped around the vertical support column of the system. The coiled geometry increases the external surface area exposed to ambient air, allowing for additional convective cooling of the water as it travels to and from the elevated cooling unit. This design is particularly advantageous in hot, arid climates where ambient air can be leveraged to improve system efficiency without increasing energy input.

[0066] These variations in geometry and dimension enable the water channel 200 to support multiple operational modes while preserving a closed-loop, gravity-assisted recirculation flow that improves cooling performance and reduces water and energy waste.

[0067] Referring now to FIGS. 3A, 3B and 3C, there are shown a perspective view, a front view and a top view, respectively, of a water tank 300 (such as the water tank 112 shown in FIG. 1), in accordance with an embodiment of the present disclosure. As shown, the water tank 300 comprises a water inlet 302 and a water outlet 304, each configured to facilitate a closed-loop water circulation pathway between the tank and the elevated cooling unit.

[0068] In one exemplary configuration, the water tank 300 has a footprint measuring approximately 800 mm by 800 mm and a height of approximately 700 mm. In practical applications, the dimensions may be selected from a range of 600 mm to 1000 mm in width and 500 mm to 900 mm in height depending on the desired water storage volume and available space beneath the table. The geometric form of the tank, which is tapered from a wider base to a slightly narrower top, provides structural stability while conserving usable volume and enabling efficient integration into the supporting base structure of the outdoor cooling system 100.

[0069] The water inlet 302 is disposed along the upper portion of the tank and is configured to receive water returned from the cooling unit via the return pipe (such as return pipe 116 of FIG. 1). This inlet may also serve as a port for manually refilling the tank during maintenance operations. The water outlet 304 is located at a lower section of the tank and is connected to the lifting pipe (such as lifting pipe 114 of FIG. 1) via the pump 118. The placement of the outlet at a low position ensures near-complete utilization of stored water and supports continuous circulation.

[0070] In one scenario, the tank 300 is fabricated from rotationally molded polyethylene with internal ribs to resist deformation under hydraulic load. In another variation, the tank may incorporate a translucent or semi-transparent wall section to visually indicate water level for maintenance personnel. Alternative implementations may integrate internal baffles to reduce turbulence during pump operation, thereby preventing cavitation and improving long-term pump performance.

[0071] Such design and dimensional features of the water tank 300 enable robust, space-efficient, and easily maintainable water storage within a compact base footprint, which are crucial for the reliable operation of the canopy-based outdoor cooling system.

[0072] Referring now to FIGS. 4A, 4B and 4C, there are shown a perspective view, a front view and a top view, respectively, of a cooling unit stand 400, in accordance with an embodiment of the present disclosure. The cooling unit stand 400 supports a cooling unit (such as the cooling unit 106 shown in FIG. 1) and is positioned above the water tank to facilitate both elevation and airflow distribution.

[0073] As shown in the illustrated embodiment, the cooling unit stand 400 comprises a plurality of air vents 402 (such as air vents 110 shown in FIG. 1). Each air vent 402 is disposed on a corresponding side surface of the stand to enable downward projection of cooled air from the elevated cooling unit. In the depicted example, the stand 400 has a generally inverted pyramidal shape with a square base and four trapezoidal sides tapering downward. One rectangular air vent 402 is located on each of the four sides of the stand, each measuring approximately 200 mm in width. In other implementation forms, the air vent width may be selected from a range of 150 mm to 300 mm, depending on the required airflow capacity and cooling coverage.

[0074] The air vents 402 are not limited to rectangular geometries. In alternate embodiments, the vents may be circular, square, elliptical or hexagonal, and may feature fixed or adjustable louvers for dynamic airflow redirection. Further, more than one air vent 402 may be positioned on a single side of the stand to increase throughput or enable multizonal cooling patterns. In a larger variation of the stand 400, such as one configured in an inverted octagonal pyramidal shape, the structure may include up to eight sides, each with one or more vents 402. Such configurations allow broader directional air distribution and can be optimized for group seating arrangements in circular or semi-circular formations.

[0075] The stand 400 also includes an internal air distribution panel located below the cooling unit and above the drainage pipe. This panel serves to evenly direct airflow toward each of the air vents 402 and prevent pressure differentials between different vent paths. By separating the cooling unit from direct contact with the drainage zone and elevating it above the internal airflow distribution plane, the stand 400 promotes balanced and uninterrupted air dispersion during operation.

[0076] This modular and geometry-flexible design of the cooling unit stand 400 allows for customization based on seating arrangement, climate intensity and installation space, while ensuring effective downward air delivery and structural support for the elevated cooling unit.

[0077] Referring now to FIGS. 5A, 5B and 5C, there are shown a perspective view, a front view and a top view, respectively, of the canopy-based outdoor cooling system 100 shown in FIG. 1, in accordance with an embodiment of the present disclosure. The views illustrate the structural integration of the cooling unit, canopy, support column, table, and water tank into a single modular assembly intended for use in outdoor environments.

[0078] In the illustrated configuration, the overall height of the system 100 is approximately 3050 mm, with the canopy mounted at a height of 1920 mm above the ground. The cooling unit, positioned atop the canopy, adds an additional 600 mm to the uppermost structure. The canopy itself spans a width of 2800 mm from tip to tip, providing substantial shading coverage for individuals seated around the central table.

[0079] The table has a circular top with a diameter of 1800 mm and is centrally supported above the water tank. The water tank, previously described with reference to FIGS. 3A, 3B and 3C, is embedded into the base of the structure and contributes to system stability in addition to serving as the reservoir for the evaporative cooling cycle. The table is positioned at a height of approximately 700 mm from the ground to match ergonomic seating height for adult users.

[0080] The system 100 also includes four foldable arms extending outward from the cooling unit, each supporting a portion of the canopy. These foldable arms allow for easier transport and deployment of the unit, especially in pop-up installations or mobile hospitality scenarios.

[0081] From the top view (FIG. 5C), the canopy is shown as a square frame with a central circular cutout to accommodate the base of the cooling unit. This configuration allows downward airflow from the unit to be distributed symmetrically via angularly adjustable air vents mounted underneath the canopy, such as air vents 110 previously described with reference to FIG. 1.

[0082] This integrated configuration of the canopy-based outdoor cooling system 100 enables efficient spatial organization and functional synergy between shading, seating, and cooling elements, offering comfort, aesthetics, and utility in a compact footprint suitable for cafés, event venues, parks, and other semi-open spaces.

[0083] Referring to FIG. 6, there is shown an example operating scenario of the system 100 shown in FIG. 5, in accordance with an embodiment of the present disclosure. As shown, multiple chairs are arranged around the canopy-based outdoor cooling system 100.

[0084] This arrangement enables individuals to be comfortably seated in shaded conditions while benefiting from directed airflow delivered downward from the elevated cooling unit. The centrally positioned air vents, configured beneath the canopy, allow cool air to be distributed evenly around the seated area, ensuring that all occupants receive a consistent cooling effect regardless of their orientation.

[0085] Such a configuration is particularly well-suited for outdoor cafés, restaurant patios, resort lounges, or public seating zones, where comfort and ambient temperature control play a significant role in user experience. By unifying cooling, shading and seating into a single system, the setup offers a practical and aesthetically cohesive solution for enhancing outdoor thermal comfort in warm environments.

Accordingly, this disclosure should not be construed as limiting the scope of the example embodiments herein.

[0033]Referring to FIG. 1, there is shown a perspective view of a canopy-based outdoor cooling system 100, in accordance with an embodiment of the present disclosure. The system 100 is designed to deliver evaporative cooling to individuals seated around a table in outd...

TECHNICAL FIELD

[0001] The present invention relates to an outdoor cooling system for shaded seating areas. The system comprises a canopy mounted above a table, a cooling unit disposed on top of the canopy, a set of adjustable air vents disposed beneath the canopy, and a water circulation mechanism for enabling evaporative cooling.BACKGROUND

[0002] Outdoor cooling systems for shaded seating are often deployed in parks, resorts, cafés, and other outdoor environments where heat mitigation is essential for comfort. Traditional approaches range from misting umbrellas to evaporative air units, yet these systems frequently suffer from structural limitations, inefficient cooling methods, or operational complexity. While various designs have emerged to improve outdoor comfort, many of these systems fail to provide integrated, self-contained solutions that balance portability, performance, and control.

[0003] Chinese Utility Model CN207912250U discloses an umbrella structure incorporating an evaporative cooling mechanism. The system features a cloth canopy with a water-absorbent inner layer and includes a fan and spray mechanism to distribute cool air. However, the design lacks any integrated structure for seated usage or any defined placement of the water tank and pump system. Additionally, it does not include electronically adjustable airflow, air vent directionality, or intelligent operational control, which limits its cooling efficiency and adaptability in varied outdoor scenarios.

[0004] U.S. Pat. No. 6,886,759B1 describes a water misting umbrella that utilizes a network of spray nozzles integrated into the umbrella canopy. This design allows mist to be delivered using an external pressurized water source, providing relief in hot environments. Nonetheless, it does not feature any fan-assisted air movement, internal water storage, or pumping components. The system also lacks self-sufficiency, requiring continuous connection to external plumbing, and offers no electronic controls or integration for temperature regulation.

[0005] United States Patent Application US20120103376A1 outlines a free-standing umbrella equipped with a misting system capable of atomizing water droplets under the canopy. The system includes a spray manifold and a control mechanism for regulating mist based on ambient air temperature. Despite these enhancements, the invention is reliant on misting alone for cooling and does not incorporate airflow components such as fans or motors. It also lacks a recirculating water system, and does not provide electronic or programmable control through a centralized logic unit.

[0006] Chinese Patent Application CN110786606A describes an outdoor umbrella air conditioning device that includes a control system and dual canopy surfaces. The device uses sensors to detect human presence and ambient conditions and powers an internal air conditioning unit accordingly. While this system addresses some automation aspects, it relies on a chassis-mounted battery-powered AC compressor, which increases complexity and weight. Furthermore, it lacks an evaporative cooling mechanism with a recirculating water loop, omits directional vent control, and does not provide for lightweight construction suited to portable shaded seating use cases.

[0007] It will be appreciated that while the above systems contribute incrementally to outdoor cooling, each suffers from notable limitations. Some require external infrastructure, such as pressurized water or electrical outlets. Others do not include airflow modulation through fans or directional vents, while several lack closed-loop water circulation or programmable control systems. These deficiencies hinder their effectiveness, usability, and deployment in public or commercial spaces where efficient, self-contained, and controllable cooling is necessary.SUMMARY

[0008] The present disclosure provides a canopy-based outdoor cooling system. The system comprises a canopy mounted above a table and a cooling unit disposed on top of the canopy. The cooling unit comprises a fan and a motor connected to the fan, wherein the fan is configured to generate airflow. A plurality of air vents is disposed underneath the canopy, each vent being operatively connected to the cooling unit and angularly adjustable within a range of 30 to 90 degrees to direct cooled air downward toward the table. The system further comprises a water tank positioned beneath the table for storing water, a pump connected to the water tank and a lifting pipe for delivering water from the tank to the cooling unit, and a return pipe configured to return excess or condensed water from the cooling unit to the water tank. A printed circuit board (PCB) is connected to both the motor and the pump and is configured to control their operation for consistent and effective delivery of cool air through the air vents. This configuration facilitates targeted and recirculated evaporative cooling in outdoor seating environments while maintaining a self-contained and electronically coordinated structure.

[0009] In one implementation form, the cooling unit comprises an enclosure fabricated from ultraviolet light-resistant plastic or lightweight and durable aluminum. This material configuration improves weather resistance while maintaining structural integrity and portability.

[0010] In another implementation form, the cooling unit further comprises an automatic drain valve connected to the return pipe, the automatic drain valve being configured to discharge excess or condensed water from the cooling unit into the water tank. This allows for uninterrupted operation while reducing the risk of water accumulation or overflow.

[0011] In another implementation form, the cooling unit further comprises a dust filter positioned to filter dust from air entering the cooling unit. This helps improve air quality and prevent contamination of internal components.

[0012] In a further implementation form, the cooling unit further comprises a cellulose pad configured to retain water, wherein the cellulose pad facilitates evaporative cooling of air passing through the pad. This design enhances cooling efficiency by leveraging evaporative principles within the airflow stream.

[0013] In one implementation form, the cooling unit further comprises a water distributor configured to distribute water received from the lifting pipe across the cellulose pad. This ensures uniform saturation of the cellulose pad and optimizes the evaporation surface area.

[0014] In another implementation form, the cooling unit further comprises a water collection basin configured to collect excess water flowing through the cellulose pad. This supports a closed-loop water circulation system and helps minimize water waste.

[0015] In yet another implementation form, the cellulose pad is fabricated from treated, mold-resistant compressed cardboard or cellulose paper. This improves durability and hygiene while maintaining efficient moisture retention.

[0016] In one implementation form, each of the air vents is disposed at a downward angle of 60 degrees relative to the canopy. This orientation provides efficient and directed airflow to users seated around the table.

[0017] In another implementation form, the fan comprises blades fabricated from reinforced plastic or light aluminum. This construction offers a balance between weight reduction and structural performance.

[0018] In a further implementation form, the motor comprises copper coils or aluminum coils, a stainless steel casing, and a thermoplastic housing. These features enable reliable motor function under varying environmental conditions.

[0019] In another implementation form, the pump is disposed within a pump housing fabricated from water-resistant reinforced plastic. This design protects pump components from environmental damage and extends service life.

[0020] In a further implementation form, the pump is connected to a pump motor comprising copper coils or aluminum coils. This allows for efficient electrical operation while offering material flexibility based on manufacturing preferences.

[0021] In another implementation form, each of the lifting pipe and the return pipe is fabricated from reinforced plastic or stainless steel. These materials provide mechanical strength and corrosion resistance for the water transport channels.

[0022] In one implementation form, the PCB is disposed outside the cooling unit. This placement protects sensitive electronics from water exposure and improves maintainability.

[0023] In another implementation form, the PCB is communicatively connected to a control system comprising a wall-mounted control unit and a remote control. This enables wireless user interaction and allows flexible control over cooling system functions from a distance.

[0024] It is to be appreciated that all the aforementioned implementation forms can be combined. All steps which are performed by the various entities described in the present disclosure as well as the functionalities described to be performed by the various entities are intended to mean that the respective entity is adapted to or configured to perform the respective steps and functionalities. It will be appreciated that features of the present disclosure are susceptible to being combined in various combinations without departing from the scope of the present disclosure as defined by the appended claims. Additional aspects, advantages, features, and objects of the present disclosure would be made apparent from the drawings and the detailed description of the illustrative implementations construed in conjunction with the appended claims that follow.BRIEF DESCRIPTION OF FIGURES

[0032] The example embodiments herein and the various features and advantageous details thereof are explained more fully with reference to the non-limiting embodiments that are illustrated in the accompanying drawings and detailed in the following description. Descriptions of well-known components and processing techniques are omitted to not unnecessarily obscure the embodiments herein. The description herein is intended merely to facilitate an understanding of ways in which the example embodiments herein can be practiced and to further enable those of skill in the art to practice the example embodiments herein. Accordingly, this disclosure should not be construed as limiting the scope of the example embodiments herein.

[0033] Referring to FIG. 1, there is shown a perspective view of a canopy-based outdoor cooling system 100, in accordance with an embodiment of the present disclosure. The system 100 is designed to deliver evaporative cooling to individuals seated around a table in outdoor environments, such as cafés, public parks, and resorts, by integrating a canopy structure, a cooling unit, and a closed-loop water circulation mechanism. The system 100 combines passive shading with active cooling, thereby improving thermal comfort in open-air settings.

[0034] The system 100 comprises a canopy 102 mounted above a table 104. The term “canopy” as used herein relates to a broad, overhead cover configured to provide shade and structural support for associated components. In the present example, the canopy 102 is configured to support the weight of an elevated cooling unit while also functioning as a platform for distributing cooled air. The canopy 102 is mounted at a height sufficient to allow individuals to be seated comfortably underneath, while maintaining an unobstructed flow of air from the cooling system.

[0035] The system 100 further comprises a cooling unit 106 disposed on top of the canopy 102. The term “cooling unit” as used herein refers to an air-cooling apparatus configured to generate and deliver cooled air downward toward the seating area. The elevated placement of the cooling unit 106 allows gravitational air distribution and facilitates vertical separation from the water tank below. In one example, the cooling unit 106 is implemented as a desert air conditioning module and is compact in form to minimize structural load on the canopy 102. This placement also enables air to flow directly downward with minimal resistance.

[0036] The cooling unit 106 comprises a motor 108 operatively connected to a fan (not shown in the figure) configured to generate airflow. The term “motor” as used herein refers to an electric driving component configured to rotate the fan blades within the cooling unit 106. Upon activation, the motor 108 drives the fan to create a consistent suction of ambient air into the cooling unit and subsequently force the air through the internal cooling components, allowing the expulsion of cooled air toward the target area.

[0037] The system 100 further comprises a plurality of air vents 110 disposed underneath the canopy 102. The term “air vent” as used herein relates to an outlet configured to direct and discharge cooled air toward a designated area. Each air vent 110 is fluidly connected to the cooling unit 106 and is angularly adjustable within a range of 30 to 90 degrees relative to the horizontal plane of the canopy 102. This configuration allows the user to control the direction of airflow depending on sun orientation, wind conditions, and user seating arrangements. In one preferred implementation, the vents are set at a 60-degree angle to maximize downward air coverage across the entire table area.

[0038] The system 100 additionally comprises a water tank 112 positioned beneath the table 104. The term “water tank” as used herein refers to a sealed container configured to store water required for evaporative cooling. The tank 112 is positioned centrally and low to the ground to serve as a stable base for the vertical support structure. Its placement directly below the table also enables compact integration of the seating, shading, and cooling components into one unified system.

[0039] A lifting pipe 114 extends from the water tank 112 to the cooling unit 106. The term “lifting pipe” as used herein relates to a fluid conduit configured to carry water upward from the tank to the elevated cooling unit. The lifting pipe 114 is vertically mounted within the central column supporting the canopy and allows continuous water delivery to the cooling unit during system operation. Because the cooling unit is elevated, the water lifted through this pipe experiences incidental cooling as it passes through ambient airflow channels surrounding the column.

[0040] A return pipe 116 extends from the cooling unit 106 back to the water tank 112. The term “return pipe” as used herein refers to a conduit configured to transport excess or condensed water from the cooling unit downward into the water tank for recirculation. This return path ensures closed-loop operation, allowing reuse of the same water and thereby reducing consumption. As the returning water passes through the ambient zone around the canopy column, it is further cooled, which improves the thermal performance of subsequent cooling cycles.

[0041] The system 100 further comprises a pump 118 connected to the water tank 112 and the lifting pipe 114. The term “pump” as used herein relates to a motor-driven hydraulic device configured to pressurize and transport water from a reservoir to a desired elevation. The pump 118 draws water from the tank and forces it upward through the lifting pipe 114 into the cooling unit 106. The pump 118 may be actuated by an external control system or by the internal logic of the system's PCB.

[0042] A printed circuit board (PCB) 120 is connected to each of the motor 108 and the pump 118. The term “PCB” as used herein refers to a control board embedded with circuit traces and electronic components configured to coordinate and manage the operation of active system elements. The PCB 120 issues electrical signals to initiate the motor for airflow generation and activate the pump for water transfer. In some cases, the PCB may also regulate operating cycles, detect input conditions (e.g., temperature or user command), and shut down the system after a predefined cooling interval. Placement of the PCB 120 outside the cooling unit 106 helps to protect sensitive electronics from moisture exposure and heat accumulation.

[0043] During operation, the PCB 120 activates the pump 118, causing water to be drawn from the tank 112 and lifted through pipe 114 to the cooling unit 106. Inside the cooling unit 106, the water interacts with internal components to cool the incoming airflow. The motor 108 drives the fan to pull ambient air into the unit, which is cooled by water-enhanced evaporative means before being discharged through the air vents 110 toward individuals seated at the table. Excess water is directed back into the tank 112 through the return pipe 116, enabling continuous operation in a closed-loop cycle.

[0044] In one scenario, the system 100 is deployed at a coastal café where guests are seated at outdoor tables during peak afternoon heat. Upon activation, the PCB 120 initiates the motor 108 and pump 118, enabling cool air to flow through the air vents 110. The 60-degree angle of the vents ensures even coverage across the round table, enhancing customer comfort without excessive noise or mist.

[0045] In another scenario, the system 100 is used during a public outdoor event in a park. The cooling unit 106 is started in the morning and continues operation throughout the day. The pump 118 recirculates water efficiently, while the PCB 120 manages operating cycles to balance performance and energy consumption. The return pipe 116 ensures minimal water loss, allowing uninterrupted use over several hours with only a small water reservoir.

[0046] This configuration of the system 100 offers several notable technical advantages. By placing the cooling unit above the canopy, gravitational airflow is harnessed for efficient air distribution without relying on high-powered fans. The integration of a water lifting and return mechanism facilitates closed-loop cooling, which enhances sustainability by minimizing water waste. The angular adjustability of the air vents allows targeted airflow for different user setups, while the use of a PCB enables automated control of pump and motor operations for reliable and responsive cooling. Together, these features create a self-contained and adaptable cooling system suited to a variety of outdoor environments.

[0047] In one implementation form, the cooling unit 106 comprises an enclosure 122, wherein the enclosure 122 is fabricated from ultraviolet light-resistant plastic or lightweight and durable aluminum. The term “enclosure” as used herein refers to the structural housing that surrounds and protects internal cooling components, including the motor 108, fan, and evaporative elements. The enclosure 122 not only provides a physical barrier against dust, debris, and mechanical damage but also ensures thermal insulation and resistance to prolonged sun exposure. Use of UV-resistant or lightweight aluminum materials supports durability in outdoor environments while minimizing structural load on the canopy 102.

[0048] In another implementation form, the cooling unit 106 further comprises an automatic drain valve 124 connected to the return pipe 116. The term “automatic drain valve” as used herein relates to a self-actuating flow control device configured to discharge excess or condensed water from the cooling unit 106 back into the water tank 112 without requiring manual intervention. The drain valve 124 ensures that internal condensation or overflow is efficiently routed into the return pipe 116, preserving the closed-loop nature of the system and preventing accumulation of stagnant water within the cooling unit 106. The automated nature of the valve enables continuous, maintenance-free operation over extended periods.

[0049] In yet another implementation form, the cooling unit 106 further comprises a dust filter 126 positioned to filter dust from air entering the cooling unit 106. The term “dust filter” as used herein refers to a porous or mesh barrier configured to remove airborne particulates from the incoming airflow before it interacts with internal cooling components. The dust filter 126 is preferably mounted at an air intake opening of the cooling unit 106 to preserve the cleanliness and performance of the fan, motor 108, and other cooling media. By preventing particulate buildup, the dust filter 126 enhances airflow quality, prolongs system life, and maintains cooling efficiency, particularly in outdoor environments prone to dust and debris.

[0050] In one implementation form, the cooling unit 106 further comprises a cellulose pad 128 configured to retain water, wherein the cellulose pad 128 facilitates evaporative cooling of air passing through the cellulose pad. The term “cellulose pad” as used herein refers to a porous and moisture-absorbent medium typically fabricated from compressed cellulose or fiberboard, structured to maximize surface area for evaporative exchange. During operation, water lifted from the tank 112 via the lifting pipe 114 is distributed across the cellulose pad 128, which absorbs and retains the moisture. As the motor 108 drives airflow through the saturated pad, heat is extracted from the air via evaporation, lowering its temperature before discharge through the air vents 110. The cellulose pad 128 plays a critical role in the evaporative cooling process by serving as the primary interface between the water and the moving airstream.

[0051] In another implementation form, the cooling unit 106 further comprises a water distributor 130 configured to distribute water received from the lifting pipe 114 across the cellulose pad 128. The term “water distributor” as used herein refers to a fluid delivery mechanism, such as a channel, manifold, or series of perforated nozzles, arranged to ensure uniform dispersion of water over the surface of the cellulose pad 128. The water distributor 130 is positioned at the upper edge of the pad and is configured to minimize oversaturation or dry zones by maintaining even coverage. Uniform distribution of water enhances evaporative efficiency and prevents material degradation caused by uneven moisture loading.

[0052] In yet another implementation form, the cooling unit 106 further comprises a water collection basin 132 configured to collect excess water flowing through the cellulose pad 128. The term “water collection basin” as used herein refers to a lower catchment chamber positioned beneath the cellulose pad 128, designed to collect gravitational runoff from the pad's surface. The water collection basin 132 serves as an intermediary reservoir that channels the collected water into the return pipe 116 for recirculation back to the tank 112. This feature supports water conservation, reduces wastage, and maintains the integrity of the closed-loop system during extended use.

[0053] In one implementation form, the cellulose pad 128 is fabricated from treated, mold-resistant compressed cardboard or cellulose paper. The term “treated, mold-resistant compressed cardboard or cellulose paper” as used herein refers to a class of engineered fibrous materials that have been chemically or structurally enhanced to resist microbial growth and degradation due to constant moisture exposure. This construction ensures that the cellulose pad 128 maintains its structural integrity and cooling efficiency over repeated use cycles. By using materials specifically treated to resist mold and mildew, the system 100 is better suited for long-term operation in humid environments without frequent maintenance or replacement of the cooling media.

[0054] In another implementation form, each of the air vents 110 is disposed at a downward angle of 60 degrees relative to the canopy 102. This specific angular orientation allows cooled air to be projected directly toward individuals seated at the table 104 while minimizing lateral airflow loss. A 60-degree vent angle optimizes air coverage for circular or semi-circular seating arrangements and ensures uniform temperature reduction across the shaded area. This angular configuration is particularly effective in outdoor conditions where directional airflow can be influenced by ambient wind.

[0055] In yet another implementation form, the fan (not shown) comprises blades fabricated from reinforced plastic or light aluminum. The term “reinforced plastic” as used herein refers to polymeric materials strengthened with glass fibers or similar additives to improve mechanical durability, while “light aluminum” refers to low-mass aluminum alloys with sufficient strength-to-weight ratios for efficient rotation. The lightweight nature of both materials minimizes motor load, reduces energy consumption, and improves rotational speed for generating consistent airflow through the cooling unit 106. This enhances the overall cooling performance of the system 100 while maintaining structural simplicity and material longevity.

[0056] In one implementation form, the motor 108 comprises copper coils or aluminum coils, a stainless steel casing, and a thermoplastic housing. The term “copper coils or aluminum coils” as used herein refers to the internal windings of the motor that generate magnetic fields to drive the fan. Copper provides high conductivity and efficiency, while aluminum offers cost and weight advantages. The stainless steel casing functions as a protective outer shell that resists corrosion and mechanical stress during outdoor operation. The thermoplastic housing serves as an insulating and structural enclosure for internal components. This combination of materials ensures durability, weather resistance, and consistent electrical performance under prolonged use.

[0057] In another implementation form, the pump 118 is disposed within a pump housing fabricated from water-resistant reinforced plastic. The term “pump housing” as used herein refers to the structural shell that encloses and protects the pump 118 from external moisture, dust, and impact. The pump housing is designed to operate in a humid or splash-prone environment, particularly given its proximity to the water tank 112. Fabrication from reinforced plastic improves structural stability and resistance to degradation over time, especially in outdoor or semi-permanent installations.

[0058] In yet another implementation form, the pump 118 is connected to a pump motor, wherein the pump motor comprises copper coils or aluminum coils. The term “pump motor” as used herein refers to the dedicated electric drive component that powers the pump 118 to lift water from the tank 112 to the cooling unit 106 via the lifting pipe 114. By using copper or aluminum coils, the pump motor ensures efficient energy transfer and maintains consistent hydraulic performance. The ability to select between copper and aluminum materials allows for design flexibility based on cost, availability, and thermal management requirements.

[0059] In one implementation form, each of the lifting pipe 114 and the return pipe 116 is fabricated from reinforced plastic or stainless steel. The term “reinforced plastic” as used herein refers to polymer materials strengthened with additives such as fiberglass to enhance tensile strength and durability. Stainless steel, on the other hand, provides corrosion resistance and long-term structural reliability. The use of these materials ensures that both the lifting pipe 114 and the return pipe 116 withstand continuous exposure to water flow, pressure fluctuations, and environmental elements during extended outdoor use. This enhances the overall longevity and maintenance-free operation of the water circulation system.

[0060] In another implementation form, the PCB 120 is disposed outside the cooling unit 106. This spatial separation is designed to minimize exposure of the PCB 120 to internal humidity and thermal buildup within the cooling unit. By isolating the PCB 120 from the evaporative zone, the system ensures that electronic control functions remain stable and unaffected by condensation, temperature variation, or splash risk. Placement outside the cooling unit also allows easier access for servicing, firmware updates, or external wiring integration without disassembling primary cooling components.

[0061] In yet another implementation form, the PCB 120 is communicatively connected to a control system comprising a wall-mounted control unit 134 and a remote control 136. The term “control system” as used herein refers to a combination of user interface devices that enable wireless or wired input to the PCB 120 for activating or configuring the operation of the motor 108 and pump 118. The wall-mounted control unit 134 may be installed near the seating area and used for regular operation by on-site personnel, while the remote control 136 allows for convenient activation or adjustment from a distance. This configuration supports flexible and intuitive control, making the system suitable for dynamic outdoor environments where manual access to the core electronics may be limited.

[0062] Referring to FIG. 2, there is shown a perspective view of a water channel 200 (such as the water channel of the canopy-based outdoor cooling system 100 shown in FIG. 1), in accordance with an embodiment of the present disclosure. As shown, the water channel 200 comprises a lifting pipe 202 (such as the lifting pipe 114 of FIG. 1) and a return pipe 204 (such as the return pipe 116 of FIG. 1), configured to transport water from a water tank to a cooling unit positioned above a canopy and back again.

[0063] In one example, the lifting pipe 202 has a length selected from a range of 1.5 to 3 meters, an outer diameter ranging from 10 to 20 centimeters, and a wall thickness ranging from 3 to 8 millimeters. These dimensions are selected based on the required elevation height and water flow rate for efficient cooling. A wider pipe diameter may be selected in scenarios where a higher volume of water is to be delivered to the cooling unit for rapid saturation of the cooling media, thereby improving thermal response in high-demand environments.

[0064] In another scenario, the lifting pipe 202 and return pipe 204 are implemented with varying cross-sectional geometry along their vertical length. For example, either pipe may taper toward its terminal end to increase water velocity or incorporate internal baffles to promote turbulent flow, thereby aiding pre-cooling of the water through enhanced ambient heat exchange during transit.

[0065] In yet another implementation form, one or both of the pipes 202 and 204 may be configured with a helical or coiled profile wrapped around the vertical support column of the system. The coiled geometry increases the external surface area exposed to ambient air, allowing for additional convective cooling of the water as it travels to and from the elevated cooling unit. This design is particularly advantageous in hot, arid climates where ambient air can be leveraged to improve system efficiency without increasing energy input.

[0066] These variations in geometry and dimension enable the water channel 200 to support multiple operational modes while preserving a closed-loop, gravity-assisted recirculation flow that improves cooling performance and reduces water and energy waste.

[0067] Referring now to FIGS. 3A, 3B and 3C, there are shown a perspective view, a front view and a top view, respectively, of a water tank 300 (such as the water tank 112 shown in FIG. 1), in accordance with an embodiment of the present disclosure. As shown, the water tank 300 comprises a water inlet 302 and a water outlet 304, each configured to facilitate a closed-loop water circulation pathway between the tank and the elevated cooling unit.

[0068] In one exemplary configuration, the water tank 300 has a footprint measuring approximately 800 mm by 800 mm and a height of approximately 700 mm. In practical applications, the dimensions may be selected from a range of 600 mm to 1000 mm in width and 500 mm to 900 mm in height depending on the desired water storage volume and available space beneath the table. The geometric form of the tank, which is tapered from a wider base to a slightly narrower top, provides structural stability while conserving usable volume and enabling efficient integration into the supporting base structure of the outdoor cooling system 100.

[0069] The water inlet 302 is disposed along the upper portion of the tank and is configured to receive water returned from the cooling unit via the return pipe (such as return pipe 116 of FIG. 1). This inlet may also serve as a port for manually refilling the tank during maintenance operations. The water outlet 304 is located at a lower section of the tank and is connected to the lifting pipe (such as lifting pipe 114 of FIG. 1) via the pump 118. The placement of the outlet at a low position ensures near-complete utilization of stored water and supports continuous circulation.

[0070] In one scenario, the tank 300 is fabricated from rotationally molded polyethylene with internal ribs to resist deformation under hydraulic load. In another variation, the tank may incorporate a translucent or semi-transparent wall section to visually indicate water level for maintenance personnel. Alternative implementations may integrate internal baffles to reduce turbulence during pump operation, thereby preventing cavitation and improving long-term pump performance.

[0071] Such design and dimensional features of the water tank 300 enable robust, space-efficient, and easily maintainable water storage within a compact base footprint, which are crucial for the reliable operation of the canopy-based outdoor cooling system.

[0072] Referring now to FIGS. 4A, 4B and 4C, there are shown a perspective view, a front view and a top view, respectively, of a cooling unit stand 400, in accordance with an embodiment of the present disclosure. The cooling unit stand 400 supports a cooling unit (such as the cooling unit 106 shown in FIG. 1) and is positioned above the water tank to facilitate both elevation and airflow distribution.

[0073] As shown in the illustrated embodiment, the cooling unit stand 400 comprises a plurality of air vents 402 (such as air vents 110 shown in FIG. 1). Each air vent 402 is disposed on a corresponding side surface of the stand to enable downward projection of cooled air from the elevated cooling unit. In the depicted example, the stand 400 has a generally inverted pyramidal shape with a square base and four trapezoidal sides tapering downward. One rectangular air vent 402 is located on each of the four sides of the stand, each measuring approximately 200 mm in width. In other implementation forms, the air vent width may be selected from a range of 150 mm to 300 mm, depending on the required airflow capacity and cooling coverage.

[0074] The air vents 402 are not limited to rectangular geometries. In alternate embodiments, the vents may be circular, square, elliptical or hexagonal, and may feature fixed or adjustable louvers for dynamic airflow redirection. Further, more than one air vent 402 may be positioned on a single side of the stand to increase throughput or enable multizonal cooling patterns. In a larger variation of the stand 400, such as one configured in an inverted octagonal pyramidal shape, the structure may include up to eight sides, each with one or more vents 402. Such configurations allow broader directional air distribution and can be optimized for group seating arrangements in circular or semi-circular formations.

[0075] The stand 400 also includes an internal air distribution panel located below the cooling unit and above the drainage pipe. This panel serves to evenly direct airflow toward each of the air vents 402 and prevent pressure differentials between different vent paths. By separating the cooling unit from direct contact with the drainage zone and elevating it above the internal airflow distribution plane, the stand 400 promotes balanced and uninterrupted air dispersion during operation.

[0076] This modular and geometry-flexible design of the cooling unit stand 400 allows for customization based on seating arrangement, climate intensity and installation space, while ensuring effective downward air delivery and structural support for the elevated cooling unit.

[0077] Referring now to FIGS. 5A, 5B and 5C, there are shown a perspective view, a front view and a top view, respectively, of the canopy-based outdoor cooling system 100 shown in FIG. 1, in accordance with an embodiment of the present disclosure. The views illustrate the structural integration of the cooling unit, canopy, support column, table, and water tank into a single modular assembly intended for use in outdoor environments.

[0078] In the illustrated configuration, the overall height of the system 100 is approximately 3050 mm, with the canopy mounted at a height of 1920 mm above the ground. The cooling unit, positioned atop the canopy, adds an additional 600 mm to the uppermost structure. The canopy itself spans a width of 2800 mm from tip to tip, providing substantial shading coverage for individuals seated around the central table.

[0079] The table has a circular top with a diameter of 1800 mm and is centrally supported above the water tank. The water tank, previously described with reference to FIGS. 3A, 3B and 3C, is embedded into the base of the structure and contributes to system stability in addition to serving as the reservoir for the evaporative cooling cycle. The table is positioned at a height of approximately 700 mm from the ground to match ergonomic seating height for adult users.

[0080] The system 100 also includes four foldable arms extending outward from the cooling unit, each supporting a portion of the canopy. These foldable arms allow for easier transport and deployment of the unit, especially in pop-up installations or mobile hospitality scenarios.

[0081] From the top view (FIG. 5C), the canopy is shown as a square frame with a central circular cutout to accommodate the base of the cooling unit. This configuration allows downward airflow from the unit to be distributed symmetrically via angularly adjustable air vents mounted underneath the canopy, such as air vents 110 previously described with reference to FIG. 1.

[0082] This integrated configuration of the canopy-based outdoor cooling system 100 enables efficient spatial organization and functional synergy between shading, seating, and cooling elements, offering comfort, aesthetics, and utility in a compact footprint suitable for cafés, event venues, parks, and other semi-open spaces.

[0083] Referring to FIG. 6, there is shown an example operating scenario of the system 100 shown in FIG. 5, in accordance with an embodiment of the present disclosure. As shown, multiple chairs are arranged around the canopy-based outdoor cooling system 100.

[0084] This arrangement enables individuals to be comfortably seated in shaded conditions while benefiting from directed airflow delivered downward from the elevated cooling unit. The centrally positioned air vents, configured beneath the canopy, allow cool air to be distributed evenly around the seated area, ensuring that all occupants receive a consistent cooling effect regardless of their orientation.

[0085] Such a configuration is particularly well-suited for outdoor cafés, restaurant patios, resort lounges, or public seating zones, where comfort and ambient temperature control play a significant role in user experience. By unifying cooling, shading and seating into a single system, the setup offers a practical and aesthetically cohesive solution for enhancing outdoor thermal comfort in warm environments.
