[0083] In this utility model, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used in relation to the direction shown in the accompanying drawings, or in relation to the vertical, perpendicular, or gravitational direction of the component itself; similarly, for ease of understanding and description, "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0084] Example

[0085] See Figures 1-16 As shown, a food waste disposer exhaust system includes a housing 1, within which an upper housing 2 and a lower housing 3 are detachably disposed. This design facilitates subsequent maintenance, cleaning, and component replacement.

[0086] The upper housing 2 contains a filter chamber 201 and an inner cylinder chamber 202. The filter chamber 201 contains an activated carbon box assembly 4, which adsorbs odors and harmful substances in the airflow, thus purifying the air. An air inlet chamber 101 is located on the upper housing 2 surrounding the filter chamber 201, providing an external airflow source for the system. The upper housing 2 is equipped with a cover assembly 7, which allows for easy opening or closing of the inner cylinder chamber 202, facilitating the addition or removal of kitchen waste into or from the inner cylinder assembly 5.

[0087] The inner cylinder cavity 202 is equipped with an inner cylinder assembly 5 specifically for containing kitchen waste. The inlet of the inner cylinder assembly 5 is connected to the inner cylinder cavity 202 to facilitate the entry of kitchen waste. An air outlet 531 is provided on the lower side of the inner cylinder assembly 5 for dehumidifying the kitchen waste.

[0088] A guide shroud 6 and a vortex fan 81 are installed inside the lower housing 3. When the vortex fan 81 operates, it creates a positive high-pressure zone in a specific area, which effectively guides the airflow at the air outlet 531 of the inner cylinder assembly into the heating chamber 108. During this process, the vortex fan 81 draws external cold air into the food waste treatment area of ​​the inner cylinder assembly 5. The air penetrates the food waste under convection, carrying moisture into the heating chamber 108.

[0089] A heating component 82 is installed inside the heating chamber 108 to heat the airflow entering the heating chamber 108. After heating, part of the hot air flows back into the inner cylinder cavity 202 under the guidance of the guide shroud 6, enters the basket 53 to contact the kitchen waste, removes the moisture from the kitchen waste, and then becomes cold air that sinks and flows back into the heating chamber 108, forming a thermal cycle. This accelerates the drying process of the kitchen waste, shortens the cycle, and speeds up the efficiency of kitchen waste disposal. The other part of the airflow flows to the guide plate 83, which is equipped with at least two air ducts. One air duct is connected to the filter cavity 201 where the activated carbon box group 4 is located, so that the airflow is discharged after being filtered and purified by the activated carbon box group 4; the other air duct is connected to the inner cylinder cavity 202, forming a secondary thermal cycle and realizing the recycling of airflow.

[0090] Furthermore, the air inlet chamber 101 is connected to the inner cylinder chamber 202 via a connecting channel, ensuring that fresh external air can smoothly enter the inner cylinder chamber 202, providing a stable airflow circulation foundation for the entire exhaust system. Through the aforementioned structural design and airflow circulation method, this food waste disposer exhaust system achieves effective treatment and recycling of airflow during food waste processing.

[0091] Specifically, the activated carbon box assembly 4 is a key component in the filter chamber 201 of the exhaust system of this food waste disposer. Its specific structure is as follows: The activated carbon box assembly 4 includes an activated carbon box 41 and an activated carbon box cover 42. The two are connected by a suitable connection method (such as common mechanical connection methods such as buckles and threads) to form a chamber. The chamber is filled with activated carbon, which is used to adsorb odor molecules, harmful gases and other impurities in the airflow, thereby purifying the airflow.

[0092] An activated carbon box gasket 43 is provided between the bottom of the activated carbon box 41 and the bottom of the filter chamber 201. This gasket serves a sealing and buffering function, preventing airflow leakage from the gap between the activated carbon box 41 and the bottom of the filter chamber 201, and reducing wear between them. A first vent hole is provided at the bottom of the activated carbon box 41, and a second vent hole is provided at a corresponding position at the bottom of the filter chamber 201. Both the first and second vent holes are located within the area enclosed by the activated carbon box gasket 43, ensuring that airflow can smoothly pass through the area defined by the gasket 43 and be purified by the activated carbon. Furthermore, a third vent hole is provided on the activated carbon box cover 42, through which the filtered gas is discharged.

[0093] A vent cover 44 is provided at the opening of the filter chamber 201 above the activated carbon box assembly 4. The vent cover 44 can prevent foreign objects from falling into the filter chamber 201 while ensuring normal airflow within the filter chamber 201, thus protecting the activated carbon box assembly 4 and other components.

[0094] In this embodiment, the vortex fan 81 is mounted on the fan mounting bracket 84, and an air guide shroud 85 is provided on the fan mounting bracket 84. The outer surface of the air guide shroud 85 has an arc-shaped structure, which cooperates with the guide shroud 6 to effectively guide the airflow.

[0095] Specifically, the air guide shroud 85 has an air outlet that communicates with the filter chamber 201, guiding the airflow into the filter chamber 201 and into the activated carbon box assembly for filtration and discharge.

[0096] The connecting channel extends along the upper arc surface of the air guide shroud 85. This design makes full use of the structural characteristics of the arc shape, allowing the connecting channel to be rationally laid out within a limited space. At the same time, the extension of the upper arc surface helps to reduce airflow resistance within the connecting channel, ensuring that airflow can smoothly enter the inner cylinder cavity 202 from the air inlet cavity.

[0097] In this embodiment, the airflow guide plate consists of an exhaust frame 831, a left cover 832, and a right cover 833. The exhaust frame 831 serves as the main structure of the airflow guide plate, providing support and guiding the airflow. The left cover 832 and the right cover 833 are respectively distributed on the left and right sides of the exhaust frame 831. They cooperate with the exhaust frame to form an air duct that communicates with the filter chamber 201, ensuring that a portion of the airflow after heating can smoothly enter the filter chamber 201 for purification. In addition, the exhaust frame 831 also has an air duct that communicates with the inner cylinder cavity 202, allowing another portion of the airflow to flow back to the inner cylinder cavity 202, forming a secondary heat circulation.

[0098] In this embodiment, the heating component 82 is a key component in the exhaust system of the food waste disposer that heats the airflow. It mainly consists of a U-shaped heating coil 821. The U-shaped heating coil is made of a suitable conductive material and generates heat when energized, heating the passing airflow to remove moisture and any remaining odors. The U-shaped heating coil 821 is mounted on a U-shaped heating coil mounting bracket 822, which provides stable support for the U-shaped heating coil, ensuring its stable position during operation and preventing shaking or displacement from affecting the heating effect.

[0099] A temperature sensor mounting bracket 823 is provided on one side of the U-shaped heating coil mounting bracket 822. The temperature sensor mounting bracket 823 provides a reliable mounting position for the temperature sensor 824, and its structure can be designed according to actual needs, using common mechanical fixing methods such as slot type or screw fixing. The temperature sensor 824 is mounted on the temperature sensor mounting bracket 823, which can monitor the temperature of the heating area in real time and feed the temperature signal back to the control system (control panel), so that the control system can adjust the power of the U-shaped heating coil 821 according to the actual temperature, thereby achieving precise temperature control.

[0100] In this embodiment, the inner cylinder assembly 5 includes a base 51, a filter 52, and a basket 53. The base 51 is located at the bottom of the inner cylinder cavity 202, providing support. The basket 53 is mounted on the base 51, facilitating its removal and insertion from the inner cylinder cavity 202 for cleaning kitchen waste. The filter 52 is located inside the basket 53, dividing the inner space of the basket 53 into an upper basket cavity and a lower basket cavity. The air outlet 531 of the inner cylinder assembly 5 communicates with the lower basket cavity. Driven by a vortex fan, the airflow inside the inner cylinder assembly 5 flows downward into the lower basket cavity and then exits through the air outlet 531, carrying away moisture from the kitchen waste in the process. The filter 52 separates the kitchen waste, preventing blockage of the air outlet 531.

[0101] The cover assembly 7 is a crucial component of the upper housing 2 used for opening and closing the inner cylinder cavity 202. It consists of an upper cover liner 71 and an upper cover 72. The upper cover liner 71 is positioned at the opening of the inner cylinder cavity 202, serving a positioning and support function. One side of the upper cover 72 is hinged to the upper cover liner 71, with a hinge spring 73 cleverly integrated at the joint. The hinge spring 73 provides appropriate elasticity during the opening and closing of the upper cover, allowing it to automatically spring up to a certain angle when opening and providing a buffer when closing to prevent damage from excessive force. Simultaneously, an upper cover sealing gasket 74 is provided on the inner side of the upper cover 72. When the upper cover 72 is closed, the sealing gasket 74 fits tightly against the edge of the opening of the inner cylinder cavity 202, effectively preventing odor and airflow leakage from the inner cylinder cavity 202. The other side of the upper cover 72 is connected to the upper cover liner 71 via a snap-fit ​​connection. This connection method is simple and reliable, allowing users to quickly open and close the upper cover 72.

[0102] A control panel 102, electrically connected to the heating element and the vortex fan, is installed on the inside of the upper cover 72. As the control core of the entire exhaust system, the control panel 102 can precisely control the heating temperature of the heating element and the speed of the vortex fan according to preset programs or user operation. A light guide column 103 is provided on the control panel 102, which guides the light emitted from the indicator lights on the control panel 102 onto the upper cover 72, allowing the user to intuitively understand the working status of the exhaust system, such as running, standby, or fault.

[0103] The outer casing 1 has a dedicated power supply cavity, in which a power supply box 104 and a power supply cover 105 are installed. The power supply box 104 provides a stable installation environment for the power supply PCB board 106. The power supply PCB board 106 installed in the power supply box 104 can convert the external power supply into voltage and current suitable for the use of various components of the exhaust system, ensuring the normal operation of the entire exhaust system. The power supply PCB board 106 is electrically connected to the power socket 107.

[0104] The food waste disposer exhaust system provided in this embodiment has two modes: cold exhaust and hot circulation, to meet the needs of different usage scenarios.

[0105] When using the ventilated air mode, participate Figures 4-9 As shown, external cold air enters through the air inlets on both sides of the main body, as shown in diagram a→b. Under the rotation of the vortex fan, the air passes through the kitchen waste, is drawn into the vortex fan, and is discharged into the heating chamber where it is heated by the U-shaped heating coil, as shown in diagram c→d→e. The heated cold air, guided by the guide shroud 6, enters the basket and comes into contact with the kitchen waste, carrying away moisture, as shown in diagram f→g. This forms a cycle of c→d→e→f→g. After multiple heating cycles, the moisture in the kitchen waste is fully absorbed, and the hot air becomes cold air, passing through the air guide shroud into the activated carbon box group 4. The activated carbon absorbs the odor from the cold air and is finally discharged, achieving the effect of drying and deodorizing the kitchen waste.

[0106] When using thermal cycling mode, participate Figures 10-16 As shown, external cold air enters through the air inlets on both sides of the main body, as shown in Figure A→B. Driven by the rotation of the vortex fan, the air passes through the food waste, is drawn into the vortex fan, and is discharged into the heating chamber where it is heated by the U-shaped heating coil, as shown in Figure C→D→E. In this chamber, the cold air comes into full contact with the surface of the heating coil, causing its temperature to rise. Due to the expansion of the air due to heat, its density decreases, and the hot air, guided by the guide hood 6, enters the basket and comes into contact with the food waste, carrying away moisture, as shown in Figure F→G. This forms a thermal circulation system: C→D→E→F→G. After multiple thermal cycles, the moisture in the food waste is fully absorbed, passes through the air guide hood, enters the activated carbon box group 4, and is discharged, as shown in Figure H→I→J, achieving the effect of drying the food waste.

[0107] In summary, the exhaust system of the food waste disposer employs a gradient isolation design between the cold air entering from the inlet chamber and the hot air in the heating chamber, preventing direct contact and reducing heat loss. The guide hood 6 redirects the heated air from the heating chamber back into the inner cylinder, where it enters the basket and comes into full contact with the food waste. Because hot air is less dense, it rises, carrying away moisture as it comes into contact with the food waste. As its temperature decreases, it becomes cold air, which, being denser, sinks and flows towards the heating chamber, thus creating a highly efficient thermal cycle. This circulation method shortens the air circulation period within the system, accelerating the drying process of food waste.
