[0001] This utility model relates to the technical field essential to human life, specifically to a hot air system and a wet waste dryer. Background Technology

[0002] A wet waste dryer is a device specifically designed to process household wet waste (such as kitchen waste, fruit and vegetable scraps, etc.). Through high-temperature drying, it significantly reduces the volume of wet waste, making it easier to store and transport. Furthermore, the dried wet waste can be used as raw material for organic fertilizer or in other resource recycling programs, achieving waste reduction and resource recovery.

[0003] However, since wet waste typically contains a large amount of moisture, dryers need to evaporate most of the water through heating to achieve the drying purpose. Therefore, during the operation of a wet waste dryer, the large amount of steam emitted causes a significant amount of odor from the wet waste to be carried away, resulting in a poor user experience in an indoor environment. If activated carbon or similar filters are used, they need to be replaced regularly, increasing both operating costs and complexity, making them inconvenient to use. Utility Model Content

[0047] Example 1

[0048] Please refer to Figure 1 , Figure 2 and Figure 3 As shown, this embodiment provides a hot air system 60 for providing hot air to a container 62, including a heating element 10 and a fan 20. The heating element 10 is mounted on a frame 30. The fan 20 is spaced apart from the heating element 10 on the frame 30. The frame 30 is provided with a first air outlet channel 301 communicating with the heating element 10 and an air inlet channel 302 communicating with the fan 20. The container 62 is provided with an air inlet 1 communicating with the first air outlet channel 301 and a pressure balancing hole 2.

[0049] In this embodiment, the heating element 10 can be an electric heating wire, a ceramic heater, or an infrared heater. The temperature can be adjusted according to requirements to ensure drying efficiency. A low-noise model of fan 20 is used to reduce noise interference during operation. This not only improves the drying effect but also ensures a quiet environment, significantly enhancing the user experience. Furthermore, the design of the pressure balance hole 2 effectively prevents excessive pressure inside the container 62, eliminating high-pressure heating and controlling the heating temperature of the container 62 to be stably maintained below 100℃, such as 40℃, 45℃, 50℃, 55℃, 60℃, 65℃, 70℃, 75℃, 80℃, or 85℃. This avoids the generation of water vapor, preventing the odor of wet waste from being carried away by water vapor, greatly eliminating potential odors during the drying process and ensuring fresh indoor air. Simultaneously, precise temperature control extends the equipment's lifespan, reduces energy consumption, and aligns with environmental protection principles.

[0050] In use, the heating element 10 and the fan 20 are turned on, and hot air enters the container 62 through the first air outlet 301, evenly heating the items inside. The design of the air inlet 302 on the frame 30 ensures a continuous supply of fresh air; the pressure balance hole 2 on the container 62 effectively regulates the internal air pressure and exhausts air, maintaining hot air circulation and ensuring a stable and uniform temperature inside the container 62, avoiding localized overheating or underheating, thereby improving drying efficiency. At the same time, this design also reduces energy consumption, extends the service life of the equipment, and ensures long-term reliability and economy.

[0051] like Figure 2 As shown, in this embodiment, the fan 20 includes a first fan 201 that blows air towards the heating element 10, and a second fan 202 that blows air in the opposite direction to the first fan 201. The motor of the fan 20 is positioned in the direction of the airflow from the second fan 202. Thus, the first fan 201 guides the hot air heated by the heating element 10 into the container 62 via the first air outlet channel 301, while the second fan 202 effectively regulates the operating temperature of the fan 20, ensuring that the fan 20 operates at a suitable temperature and preventing overheating damage. Simultaneously, the dual-fan design enhances the flow and uniformity of the hot air, further improving the drying effect and optimizing the user experience.

[0052] Furthermore, such as Figure 1As shown, in this embodiment, the frame 30 is provided with a second air outlet duct 303 communicating with the second fan 202. A controller 40 electrically connected to the fan 20 is installed within the second air outlet duct 303. The heating element 10 is electrically connected to the output terminal of the controller 40. The controller 40 can be a PLC or a microcontroller; for example, the PLC model could be a Siemens S7-1200. This forms a closed-loop control system that monitors and adjusts the temperature in real time to ensure precise control. The controller 40 feeds back data through a temperature sensor, which can be a PT100 or a K-type thermocouple, offering high accuracy and stability. This allows for automatic adjustment of the heating element 10's power to maintain a constant temperature and prevent temperature fluctuations.

[0053] like Figure 2 As shown, in this embodiment, a partition plate 304 is provided between the first fan 201 and the second fan 202, and an air inlet gap 203 is provided between the partition plate 304 and the central shaft of the fan 20. The design of the partition plate can prevent the hot air heated by the heating element 10 from being carried away by the second fan 202, ensuring that most of the hot air is blown into the container 62 by the first fan 201, thereby improving thermal efficiency. The partition plate 304 is made of a high-temperature resistant material (such as ceramic fiber board or asbestos board), which extends its service life and enhances the stability of the system.

[0054] like Figure 1 As shown, in this embodiment, the frame 30 is provided with a third air outlet 305 that communicates with the pressure balance hole 2. This guides the humid and hot air discharged through the pressure balance hole 2 away from the operating area, avoiding the impact of humid and hot air on the operating environment and personnel, while maintaining dry and fresh indoor air. This design not only improves drying efficiency but also further optimizes the user experience.

[0055] like Figure 2 and Figure 3 As shown, this embodiment also includes a mounting housing 50 for accommodating the heating element 10 and the first fan 201; the mounting housing 50 includes a top shell 501 and a bottom shell 502 locked to the top shell 501, the partition plate 304 is the top plate of the top shell 501, and the first air outlet channel 301 is disposed on the bottom plate of the bottom shell 502.

[0056] Specifically, the design of the mounting housing 50 facilitates the installation and disassembly of the heating element 10 and the first fan 201, improving maintenance and assembly efficiency. It forms an independent installation module, making the overall structure more compact and easier to maintain. Simultaneously, the first air outlet duct 301 can have several through holes on the bottom housing 502, creating a direct air supply effect, ensuring that hot air directly acts on the object being dried, reducing energy loss. The sealing design of the mounting housing 50 also effectively prevents heat leakage, further improving thermal efficiency.

[0057] Example 2

[0058] like Figure 4 , Figure 5 and Figure 6 As shown, this embodiment provides a wet waste dryer, including a hot air system 60, an outer shell structure 61, and a container 62. The hot air system 60 is as described in Embodiment 1. The outer shell structure 61 is provided with a cylindrical body 611 and an outer cover 612 that is closed or opened with the cylindrical body 611. A sealing cover 621 is provided on the top surface of the container 62. The container 62 is fitted or separated inside the cylindrical body 611. The hot air system 60 is located inside the outer cover 612, and the first air outlet channel 301 of the hot air system 60 is provided through the sealing cover 621. The pressure balance hole 2 of the hot air system 60 is provided on the sealing cover 621.

[0059] The wet waste dryer in this embodiment forms an independent dryer that can be used by connecting to mains electricity. It is easy to operate and suitable for home environments. By controlling the drying temperature, only a small amount of moisture evaporates, preventing the odor of wet waste from being carried away by the steam during the drying process. This ensures relatively fresh indoor air while improving drying efficiency and reducing energy consumption.

[0060] Furthermore, container 62 can be removed from cylinder 611 for cleaning, or for pouring in or emptying dried wet waste, facilitating daily maintenance and cleaning by users and ensuring the long-term stable operation of the equipment. The dried wet waste can be used as organic fertilizer, which is both environmentally friendly and efficient, achieving resource recycling, improving household waste sorting and disposal levels, and promoting the popularization of green living concepts.

[0061] Furthermore, a sealing cap 621 is designed on the container 62 opening to form a tighter sealed space with the cylinder body 611 to prevent odor leakage; at the same time, the sealing cap 621 can be assembled with the first air outlet channel 301 to form air outlet drying from top to bottom, ensuring that hot air evenly covers the wet waste and accelerates the drying process.

[0062] like Figure 4 and Figure 5 As shown, in this embodiment, the air inlet channel 302 of the hot air system 60 is provided on the outer cover 612, and the outer cover 612 is provided with a number of openings 613 that communicate with the air inlet channel 302. For example, multiple openings 613 are arranged at equal intervals on the side of the outer cover 612 to ensure the air intake volume and ensure the uniformity and continuity of the air intake.

[0063] like Figure 6As shown, in this embodiment, a sealing ring 622 is provided on the edge of the sealing cover 621, and a sealing groove 6121 is provided on the mating surface of the outer cover 612 to press against the sealing ring 622. The sealing ring 622 can be made of silicone or rubber, which has good high temperature resistance and sealing performance, ensuring a tight fit between the container 62 and the cylinder 611, preventing hot air leakage, and further improving drying efficiency. At the same time, the sealing ring 622 is easy to replace, has low maintenance costs, and extends the service life of the equipment. In addition, the design of the sealing groove 6121 of the outer cover 612 forms a good sealing structure, effectively isolating outside air, avoiding heat loss, and further optimizing the drying effect.

[0064] like Figure 4 As shown, in this embodiment, the outlets of the second air outlet 303 and the third air outlet 305 of the hot air system 60 are located on the side of the hinge portion of the outer cover 612, so that the air outlet and the opening and closing end of the outer cover 612 are in different directions. This avoids the outlets of the second air outlet 303 and the third air outlet 305 from interfering with the user's air outlet design, ensures operational safety, prevents hot air from directly contacting the human body, and improves the user experience.

[0065] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
