Description

Technical Field

[0001] This utility model relates to the field of outdoor heating devices, and more particularly to a roof heating device for outdoor cabins. Background Technology

[0002] Outdoor heating systems are widely used in open or semi-enclosed environments to enhance user comfort, with rooftop heating systems for outdoor cabins being particularly suitable. These systems utilize infrared radiation or a combination of convection and radiation to evenly heat the space from top to bottom, quickly warming the cabin and reducing cold air convection. Their main functions include efficient heating, energy consumption control, and multiple safety protections, making them suitable for outdoor cafes, patios, sunrooms, and other similar settings. Rooftop installation not only saves space but also provides more even heat distribution, making it an ideal choice for enhancing the outdoor cabin experience during cold seasons.

[0003] The design of outdoor heating systems needs to balance efficiency, stability, and adaptability to complex environments. While rooftop heating systems excel in energy utilization and heat distribution, the continuity of energy supply and ease of system maintenance become key considerations during extended operation in cold seasons. This is especially true for systems employing water-circulating heating schemes, which must fully leverage the advantages of clean energy sources such as solar power while ensuring a smooth switch to auxiliary heating sources under special conditions to meet uninterrupted heating needs.

[0004] Therefore, while existing water-circulating heating technologies can meet certain heating needs, they still have some shortcomings in practical applications. For example, a single heating source is prone to heating interruptions when there is insufficient sunlight or limited fuel, affecting system stability. Furthermore, circulating water is prone to accumulating impurities and scale over long-term use, which can lead to pipe blockage, decreased heat exchange efficiency, and increased system maintenance frequency. These problems limit the long-term efficient operation and adaptability of existing technologies in complex environments.

[0005] To address the above problems, a roof heating device for outdoor cabins is proposed. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a roof heating device for outdoor cabins, which aims to solve the problems of heating interruption caused by a single heating source in the prior art, as well as the problems of equipment wear and frequent maintenance caused by the accumulation of impurities and scale in the circulating water.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a roof heating device for an outdoor cabin, comprising a solar heating component, water pumps on both sides of the solar heating component, the two sides of the solar heating component being connected to the ports of the two water pumps via a return water pipe and an outlet water pipe, respectively, and the other ports of the two water pumps being connected to the interior of a hot water storage tank via pipes, a cleaning mechanism being provided inside the return water pipe near the side of the solar heating component, three ring-shaped support legs being installed at the bottom of the hot water storage tank, an electric heating component being provided inside the hot water storage tank, and an outlet water pipe and a return water pipe being provided on the side wall of the hot water storage tank, and connected to a heating pipe via a heating pump; The cleaning mechanism includes a cleaning cylinder with an internal thread on its inner side and an external thread on the outer side of the return water pipe. The cleaning cylinder is threaded to the end of the return water pipe, and a cleaning assembly is provided between the return water pipe and the interior of the cleaning cylinder.

[0008] As a further description of the above technical solution: The cleaning assembly includes a driven fan blade and a cleaning brush, which are connected by a connecting rod, and a fixed block is rotatably connected to the outer side of the middle part of the connecting rod.

[0009] As a further description of the above technical solution: The cleaning brush is located inside the cleaning cylinder, and the fine bristles on the outer side of the cleaning brush rotate to clean the internal filter holes of the cleaning cylinder.

[0010] As a further description of the above technical solution: Both the driven fan blade and the fixing block are engaged with the inner wall of the return water pipe.

[0011] As a further description of the above technical solution: The solar heating assembly includes a support frame, inside which multiple solar heating tubes are installed side by side, and a water storage tank is provided on top of each solar heating tube.

[0012] As a further description of the above technical solution: The cleaning cylinder is located inside the water storage tank.

[0013] As a further description of the above technical solution: The electric heating assembly includes an electric heater, the output end of which is connected to an electric heating copper tube located inside the hot water storage tank. The electric heater is located at the bottom of the hot water storage tank. A temperature detector is installed inside the hot water storage tank and is electrically connected to the electric heater.

[0014] As a further description of the above technical solution: One end of the heating pipe is connected to the output end of the heating pump, the input end of the heating pump is connected to the second outlet pipe, and the other end of the heating pipe is connected to the second return pipe. The heating pipe is buried inside the roof.

[0015] This utility model has the following beneficial effects: 1. In this invention, solar heating tubes are used to heat the water in the storage tank. A pump circulates the hot water to the top for heating. When the solar water temperature is insufficient, the system automatically activates an electric heater via a temperature sensor to heat the copper heating tubes inside the storage tank, ensuring continuous and efficient heating of the cabin. This design fully utilizes renewable energy while ensuring heating performance under low light conditions, combining environmental friendliness and stability.

[0016] 2. In this utility model, to address the potential issues of impurities and scale buildup in the water circulation system, a filter cartridge is installed at the inlet of the water storage tank, equipped with a hydrodynamic impeller cleaning device. The hydrodynamic impeller uses water flow to drive the brushes to automatically clean the filter screen, effectively preventing clogging and efficiency reduction caused by impurity accumulation. Furthermore, the threaded connection between the filter cartridge and the pipe facilitates convenient replacement later. This innovative design significantly improves the cleanliness of the circulating water, extends the system's service life, and reduces maintenance costs, ensuring the long-term stable operation of the heating system.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a roof heating device for outdoor cabins, comprising a solar heating component 1, a water pump 2, a hot water storage tank 5, heating pipes 13, and a series of cleaning, heating, and control components. This device primarily provides efficient and stable roof heating for outdoor cabins through a combination of solar and electric heating.

[0021] The solar heating module 1 consists of a support frame 101 and multiple solar heating tubes 102. The solar heating tubes 102 are installed side by side inside the support frame 101, and a water storage tank 103 is provided on top for temporary storage of solar-heated water. Water pumps 2 are connected to both sides of the solar heating module 1. The ports of the water pumps 2 are connected to the solar heating module 1 through a return water pipe 3 and an outlet water pipe 4, forming a water circulation system. The other ends of both water pumps 2 are connected to the interior of a hot water storage tank 5 through pipes, allowing the heated water to be stored and transported to the heating system.

[0022] The hot water storage tank 5 is the core heat storage device of the entire system. Three ring-shaped support legs 11 are installed at its bottom for support and stability. An electric heating assembly 12 is integrated inside the hot water storage tank 5. The electric heating assembly 12 includes an electric heater 1201 and an electric heating copper tube 1202. The electric heater 1201 is located at the bottom of the hot water storage tank 5, and its output end is connected to the electric heating copper tube 1202 inside the tank, directly heating the water inside to maintain the water temperature. The hot water storage tank 5 also has a built-in temperature detector, electrically connected to the electric heater 1201. When the water temperature is lower than the set value, the electric heater 1201 automatically starts to provide auxiliary heating. A second outlet pipe 6 and a second return pipe 7 are provided on the side wall of the hot water storage tank 5. The second outlet pipe 6 is connected to the input end of the heating pump 8, and the output end of the heating pump 8 is connected to the heating pipe 13 to deliver hot water to the heating system. The heating pipes 13 are buried inside the roof to form an efficient roof heating network. The circulating hot water enters the hot water storage tank 5 again through the return pipe 2 7, realizing closed-loop operation.

[0023] Reference Figure 2To address potential impurities during the water return process, a cleaning mechanism 9 is installed on the side of the return water pipe 3 near the solar heating component 1. The cleaning mechanism 9 includes a cleaning cylinder 901 with an internal thread 902 that connects to the external thread 10 on the outside of the return water pipe 3. A cleaning assembly is located inside the cleaning cylinder 901, comprising a driven fan blade 904 and a cleaning brush 903, connected by a connecting rod 906. The outer side of the middle section of the connecting rod 906 is rotatably connected to the inner wall of the return water pipe 3 via a fixing block 905. The cleaning brush 903 is located inside the cleaning cylinder 901, and its fine bristles are used to clean the filter holes inside the cleaning cylinder 901, preventing impurities from clogging the pipe. The cleaning cylinder 901 is directly installed inside the water storage tank 103 to clean impurities from the water returning to the water storage tank 103.

[0024] Working Principle: This equipment achieves efficient heating by combining a solar heating component 1 with a hot water storage tank 5. The solar heating element 1's solar heating tube 102 absorbs heat, and the heated water is pumped by a water pump 2 through an outlet pipe 4 to the hot water storage tank 5. Cold water returns to the solar heating component 1 through a return pipe 3, forming a cycle. When solar energy is insufficient, the electric heating component 12 in the hot water storage tank 5 is activated. The electric heater 1201 heats the electric heating copper tube 1202, increasing the water temperature to maintain heating demand. Hot water in the hot water storage tank 5 enters the heating pipe 13 through an outlet pipe 6 and a heating pump 8. The pipe is buried inside the roof for top heating, and the cooled water returns to the hot water storage tank 5 through a return pipe 7. Simultaneously, the cleaning mechanism 9 in the return pipe 3 removes impurities using a cleaning cylinder 901 and a cleaning brush 903, ensuring efficient system operation.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
