Description

Technical Field

[0001] This utility model relates to the field of food waste processing technology, specifically a food waste processor with an air duct assembly. Background Technology

[0002] A food waste processor is a device used to process kitchen waste. It alters the physical form of the waste through mixing and crushing, and removes some moisture through heating and filtration, thereby reducing the volume and weight of the waste. Some food waste processors also incorporate biological treatment technologies such as microbial fermentation, which decomposes and transforms organic components under the action of microorganisms, further reducing the total amount of waste.

[0003] However, regardless of whether physical or biological methods are used, the processing inevitably involves issues of heating and odor control. To reduce odors during processing, existing food waste disposers are typically equipped with airflow circulation or suction devices. These devices force airflow to move the gas inside the food waste bin, removing and treating the odorous gases. To effectively extract the dispersed gases inside the food waste bin, such devices often require significant power and size, occupying considerable internal space and hindering miniaturization design.

[0004] Therefore, it is necessary to optimize the airflow system of the food waste processor to reduce the size of the airflow delivery components and their internal space occupation, while improving the gas flow and suction efficiency, thereby balancing deodorization effect and equipment compactness.

[0010] Furthermore, in some embodiments of this utility model, the mounting cavity includes a first opening of the mounting cavity communicating with the first air intake channel and a second opening of the mounting cavity communicating with the second exhaust channel.

[0030] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings. The described embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0031] It should be noted that all directional indications in this utility model embodiment, such as (up, down, left, right, front, back, etc.), are only used to explain the relative positional relationship and movement of each component in a specific posture (as shown in the attached figure). If the specific posture changes, the directional indication will also change accordingly.

[0032] Furthermore, the use of terms such as "first" and "second" in this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0033] like Figures 1 to 14 A food waste disposer with an air duct assembly is shown, comprising a housing 1, wherein the housing 1 has a first accommodating cavity 2 and an air inlet 21 communicating with the first accommodating cavity 2, the first accommodating cavity 2 has a food waste bin 3, an air duct assembly 4, and an airflow conveying assembly 5 located within the air duct assembly 4, the food waste bin 3 has a food waste chamber 31 communicating with the air inlet 21, the air duct assembly 4 includes a first air duct housing 45, the first air duct housing 45 has a first opening 401 communicating with the food waste chamber 31, a first air intake channel 41 communicating with the first opening 401, a second opening 402 communicating with the outside, a second exhaust channel 42 transferring gas to the outside of the second opening 402, and an installation cavity 43 for accommodating the airflow conveying assembly 5, the installation cavity 43 being disposed between the first air intake channel 41 and the second exhaust channel 42, the airflow conveying assembly 5 having an air inlet 51 communicating with the first air intake channel 41 and an air outlet 52 communicating with the second exhaust channel 42, the first air duct housing 45 being integrally formed.

[0034] The first air duct housing of this utility model adopts an integrated molding structure, which simplifies the production process and enhances the structural strength and sealing performance. By concentrating the gas input, output and airflow delivery components in the first air duct housing, the use of multiple dispersed pipes or connecting parts in traditional technology is avoided, which greatly reduces the installation space required for the airflow delivery system. This allows the food waste processor to achieve efficient gas transfer function even with a limited overall volume, improving space utilization efficiency and product design compactness.

[0035] Furthermore, as a preferred embodiment of this utility model and not a limitation thereof, the airflow conveying component operates within the first air duct housing, thereby driving the gas in the food waste chamber into the first air intake channel. Under the action of the airflow conveying component, the gas is directionally transferred to the outside along the second exhaust channel, thereby reducing resistance and leakage during gas flow, improving gas transfer efficiency, reducing energy consumption, and solving the problem of low gas transfer efficiency caused by the high power required for airflow conveying components in traditional technologies to draw in dispersed gas.

[0036] Specifically, the first air duct housing is integrally molded, which simplifies the manufacturing process and assembly flow of the product and reduces production costs. On the other hand, it avoids the problems of complex structure, difficult sealing, easy air leakage, and insufficient strength caused by splicing, welding or bonding of multiple parts in traditional technology. It improves the overall structural strength, airtightness and durability of the air duct housing, and ensures the stability and safety of the gas delivery process. The airflow delivery component is set in the installation cavity inside the first air duct housing, which improves the stability and response speed of gas delivery. The airflow delivery component can maintain effective negative pressure and airflow circulation without high power, which not only reduces energy consumption and operating noise, but also facilitates the use of smaller and lower cost airflow drive devices, further supporting the overall system's lightweight and quietness.

[0037] Alternatively, in some embodiments, the pneumatic delivery component is not limited to a fan or an air pump.

[0038] like Figures 2 to 11 The food waste disposer shown has an air duct assembly, wherein the first air intake channel 41 and / or the second exhaust channel 42 are provided with a turning end 44, the direction of airflow entering the air intake 51 intersects the direction of airflow exiting the air exhaust 52, and the height of the air intake section of the first air intake channel 41 is greater than the height of the air intake section of the second exhaust channel 42.

[0039] Furthermore, as a preferred embodiment of the present invention and not a limitation thereof, the first air intake channel and / or the second exhaust channel are provided with a turning end, so that the airflow changes direction during the process of entering the air inlet and exiting the air outlet, thereby allowing the air inlet and the air outlet to be arranged in a non-parallel or non-coaxial manner in space. Compared with the spatial interference problem caused by the consistent direction of the air inlet and outlet or the limited layout of the traditional straight-through air duct, the present invention enables the air duct component to achieve smooth airflow turning and delivery within a limited structural space, thereby improving the layout flexibility and space utilization of the overall air duct system and the internal structure of the food waste processor.

[0040] Specifically, the direction of the airflow entering the air inlet intersects with the direction of the airflow exiting the air outlet, forming a perpendicular or angled relationship. This helps to prevent the airflow from forming short-circuit circulation, turbulence, or backflow within the air duct, making the airflow path smoother and more directional. This reduces energy loss and decreased delivery efficiency caused by airflow direction conflicts, thereby improving the gas transfer capability of the airflow delivery components at relatively low power and optimizing the system's energy efficiency performance.

[0041] Specifically, the height of the air intake section of the first air intake channel is greater than the height of the air intake section of the second exhaust channel, creating a height difference in the airflow during entry and exit. Utilizing the assistance of gravity and pressure difference, this helps guide the gas to flow naturally towards the exhaust end, enhancing airflow fluidity and emission efficiency. This invention further optimizes the air pressure distribution within the duct, reducing the energy consumption required by the airflow delivery components during gas propulsion, improving the overall stability and response speed of gas transfer. It also makes the airflow movement within the duct smoother, reducing eddies, vibrations, and noise caused by uneven airflow, thus helping to reduce the pneumatic noise generated by the food waste disposer during operation.

[0042] Of course, in some embodiments, the first intake channel may be provided with a steering end, the second exhaust channel may be provided with a steering end, or both the first intake channel and the second exhaust channel may be provided with steering ends.

[0043] like Figures 2 to 11 The illustrated food waste disposer with an air duct assembly has a first air intake channel 41 and / or a second exhaust channel 42 arranged in a V-shape or L-shape. The height of the air intake section of the first air intake channel 41 is greater than the height of the air exhaust section of the first air intake channel 41, the height of the air intake section of the second exhaust channel 42 is greater than the height of the air exhaust section of the second exhaust channel 42, and the height of the air inlet 51 is greater than or equal to the height of the air outlet 52.

[0044] This invention sets the first air intake channel and / or the second exhaust channel to a V-shape or L-shape, so that the airflow can change direction in a limited space during the entry or exit process, such as vertical or oblique transition. This can effectively utilize three-dimensional space and enable the air duct assembly to achieve smooth airflow turning and delivery in a more compact structure inside the food waste processor, thereby improving the space utilization and layout rationality of the overall structure.

[0045] Of course, in some embodiments, the first intake passage may be configured as V-shaped or L-shaped, the second exhaust passage may be configured as V-shaped or L-shaped, or both the first intake passage and the second exhaust passage may be configured as V-shaped or L-shaped.

[0046] Furthermore, as a preferred embodiment of this utility model and not a limitation, the height of the air intake section of the first air intake channel is greater than the height of its exhaust section, and the height of the air intake section of the second exhaust channel is also greater than the height of its exhaust section. This allows the airflow to flow naturally downward or obliquely along the height difference direction after entering the air duct. By utilizing gravity assistance and the pressure gradient effect, the gas is guided to transfer more smoothly from the air intake end to the exhaust end, reducing the power input required by the airflow conveying components during the gas propulsion process, improving the gas transfer efficiency, and reducing system energy consumption and noise.

[0047] Specifically, the height of the air inlet is greater than or equal to the height of the air outlet, which further enhances the airflow guidance inside the duct. This allows the airflow to form a reasonable height gradient during entry and exit, which helps to build a stable airflow path and avoids backflow, eddies, or pressure imbalance caused by improper height difference. This improves the stability, uniformity, and response speed of airflow delivery, ensuring that the gas in the kitchen waste cavity can be discharged efficiently and continuously.

[0048] like Figures 2 to 11 The illustrated food waste disposer with an air duct assembly has an installation cavity 43 provided with a support platform 431 for supporting the airflow delivery assembly 5, a baffle 432 near the first air intake channel 41 for blocking water, and a guide gap 433 located between the baffle 432 and the inner wall of the installation cavity 43. The guide gap 433 connects the first air intake channel 41 and the second exhaust channel 42.

[0049] Furthermore, as a preferred embodiment of this utility model and not a limitation, the mounting cavity is provided with a support platform specifically for supporting the airflow conveying components. This platform can effectively support and position the airflow conveying components, such as fans and air pumps, ensuring that their installation position within the mounting cavity is accurate and securely fixed. This avoids displacement, poor contact, or unstable operation of the airflow conveying components due to vibration, movement, or assembly deviations, thereby improving the stability and reliability of the airflow conveying process, extending the service life of the components, and simplifying installation and maintenance operations. In addition, the support platform in the mounting cavity raises the height of the airflow conveying components, preventing direct contact between the airflow conveying components and liquids.

[0050] In some embodiments, a baffle is provided near the first air intake channel. The baffle has a water-blocking function, which can effectively prevent liquids such as water droplets, washing water or condensation in humid airflow from the food waste chamber or the first air intake channel from directly entering the area where the airflow conveying components are located. This prevents moisture from causing corrosion, short circuit or damage to key components such as motors and fan blades, and improves the safety, durability and operational stability of the air duct components and the entire food waste processor. It is particularly suitable for food waste processing environments that are humid or prone to condensation.

[0051] Furthermore, a flow guide gap is provided between the baffle and the inner wall of the mounting cavity. This flow guide gap can guide a portion of the airflow that is blocked by the baffle to bypass the baffle area and continue to flow along the set path to the second exhaust channel, thus preventing airflow backflow. On the other hand, it can also allow liquid from the waste chamber or the first air intake channel to enter the second exhaust channel through the flow guide gap.

[0052] like Figures 2 to 11 The illustration shows a food waste disposer with an air duct assembly. The airflow delivery assembly 5 includes a cover 53 and a fan 54 located inside the cover 53. The air inlet 51 is located on the side of the cover 53 facing the first air intake channel 41, and the air outlet 52 is located on the side of the cover 53 facing the second exhaust channel 42. The fan 54 is used to drive the airflow from the air inlet 51 to the air outlet 52. The direction in which the airflow enters the air inlet 51 is perpendicular to the direction in which the airflow exits from the air outlet 52. The air outlet 52 is located below the air inlet 51.

[0053] Furthermore, as a preferred embodiment of this utility model and not a limitation, the direction of airflow entering the air inlet is perpendicular to the direction of airflow exiting the air outlet. The airflow changes direction by 90° during the conveying process through the action of the fan, so that the airflow can be flexibly adjusted within a limited space, avoiding the spatial interference and airflow path restriction problems caused by the same or parallel direction of the air inlet and outlet in the traditional straight-through structure.

[0054] Specifically, the airflow delivery component integrates the fan, air inlet, and air outlet into one unit through the cover, making the process of gas entering from the first air inlet channel, being driven by the fan, and then being directionally transferred to the second exhaust channel more direct and efficient. This improves the overall integration and operational reliability of the air duct component, while also facilitating installation, maintenance, and modular design.

[0055] In addition, the exhaust vent is located below the air inlet, and combined with the vertically intersecting airflow direction, it forms an airflow delivery path from top to bottom or diagonally downward. This layout conforms to the physical characteristics of natural gas settling and flow, which helps to use gravity to assist airflow movement, reduce the energy consumption of the fan in the gas pushing process, and at the same time avoid the formation of eddies, backflow or stagnation of airflow in the duct. It optimizes the air pressure distribution and airflow organization inside the duct, improves the stability and uniformity of gas transfer, and further reduces system operating noise and vibration.

[0056] Furthermore, the fan is built into the enclosure, which effectively prevents it from coming into direct contact with moisture, dust, and other impurities, providing good physical protection and isolation. This prevents foreign objects from entering the fan and causing damage, while also reducing the external transmission of noise generated during operation, thus improving the user experience.

[0057] like Figures 2 to 11 The illustrated food waste disposer with an air duct assembly includes a mounting cavity 43 comprising a first mounting cavity opening 434 communicating with a first air intake channel 41 and a second mounting cavity opening 435 communicating with a second exhaust channel 42. The second mounting cavity opening 435 is provided with a limiting end 436 abutting against the cover 53. The second mounting cavity opening 435 allows the exhaust port 52 to extend into it. The support platform 431 is provided with a positioning end 6, and the cover 53 is provided with a locking end 7 that cooperates with the positioning end 6.

[0058] Furthermore, as a preferred embodiment of the present invention and not a limitation thereof, by setting a limiting end at the second opening of the mounting cavity and a positioning end at the support platform, and correspondingly setting a locking end on the cover, the airflow conveying component can achieve accurate positioning and directional assembly during installation.

[0059] Specifically, the limiting end of the second opening of the mounting cavity can abut against the cover, effectively limiting the displacement of the cover in the installation direction and preventing it from shifting or loosening due to vibration, airflow impact or external force during use. At the same time, the positioning end on the support platform cooperates with the locking end on the cover to further form a locking or limiting relationship in the horizontal or vertical direction, enhancing the fixed stability of the cover in the mounting cavity, ensuring that the airflow conveying component remains firmly installed during long-term operation, and improving the reliability and durability of the overall structure.

[0060] Specifically, the second opening of the mounting cavity allows the exhaust port to extend into and connect with the second exhaust channel, enabling the exhaust port to extend directly to the airflow output end, thus optimizing the smoothness of the exhaust path and the efficiency of airflow delivery. It also facilitates the alignment and positioning of the airflow delivery components.

[0061] like Figures 2 to 11 The illustrated food waste disposer has an air duct assembly. The cover 53 is arc-shaped. The positioning end 6 includes a first positioning end 61 that is inclined and a second positioning end 62 that is close to the exhaust port 52. The engaging end 7 includes a first engaging end 71 that is located close to the inner wall of the mounting cavity 43 and cooperates with the first positioning end 61, and a second engaging end 72 that is located between the first positioning end 61 and the second positioning end 62. The cover 53 includes a first cover 531 and a second cover 532 detachably connected to the first cover 531. The first cover 531 is provided with a first cover first connecting part 5311 and a first cover second connecting part 5312. The second cover 532 is provided with a second cover first mating part 5321 and a second cover second mating part 5322. The first cover first connecting part 5311 and the second cover first mating part 5321 cooperate to form a first engaging end 71, and the first cover second connecting part 5312 and the second cover second mating part 5322 cooperate to form a second engaging end 72.

[0062] Furthermore, as a preferred embodiment of this utility model and not a limitation, the cover is arc-shaped, which conforms to the streamlined path characteristics of airflow during turning and conveying. This helps to reduce the flow resistance and eddy generation of airflow during the conveying process, making the airflow smoother when it enters from the air inlet, is driven by the fan, and moves towards the air outlet, reducing energy loss and improving airflow conveying efficiency. At the same time, the arc-shaped structure can also better adapt to the internal space of the installation cavity, optimize the overall structural layout of the air duct assembly, and improve space utilization efficiency and product compactness.

[0063] Optionally, in some embodiments, the first engaging end and the second engaging end are not limited to being connected by means of groove connection, snap-fit ​​connection, mortise and tenon connection, magnetic connection, fastener connection, etc.

[0064] Specifically, the first positioning end is tilted to help guide the cover to quickly align and form a stable support during installation. The second positioning end is close to the exhaust port, which further enhances the fixation effect in the exhaust area. The first and second locking ends are located near the inner wall of the installation cavity and the middle of the cover, respectively, forming multi-point constraints to ensure that the cover is effectively fixed in multiple directions. Through the multi-directional and multi-layered positioning and locking structure, the cover can be constrained and fixed from different directions during installation. This not only allows for precise control of the cover's spatial position within the installation cavity, ensuring alignment of the airflow paths between the air inlet and the first air intake channel, and between the exhaust port and the second exhaust channel, but also effectively prevents the cover from shifting or loosening due to vibration, airflow impact, or external forces during operation, thus improving the overall stability and reliability of the structure.

[0065] Specifically, the cover adopts a split structure, including a first cover and a second cover that can be detachably connected. The first connecting part of the first cover and the first mating part of the second cover cooperate to form a first engaging end, and the second connecting part of the first cover and the second mating part of the second cover cooperate to form a second engaging end. This realizes the quick connection and firm fixation of each part of the cover, which not only simplifies the overall manufacturing and assembly process of the cover, but also facilitates the maintenance, cleaning or replacement of the internal fan, air duct or filter components when needed.

[0066] like Figures 2 to 11 The illustration shows a food waste disposer with an air duct assembly. The first air duct housing 45 has a first air duct housing opening 451 into which the airflow delivery assembly 5 extends. The air duct assembly 4 includes a second air duct housing 46 that covers the first air duct housing opening 451. The first air duct housing 45 or the second air duct housing 46 has a wiring channel 47 through which the wires of the airflow delivery assembly 5 pass. The first air intake channel 41 and / or the second exhaust channel 42 have a drain outlet 48. The drain outlet 48 is connected to a pipe or a water collection box 49. The second air duct housing 46 has an arcuate protrusion 461 that matches the shape of part of the cover 53.

[0067] Furthermore, as a preferred embodiment of this utility model and not a limitation thereof, the first air duct housing has a first opening for the airflow conveying assembly to extend into, and the second air duct housing can cover the first opening of the first air duct housing to form a complete closed air duct structure. This facilitates the insertion of the airflow conveying assembly through the first opening of the first air duct housing during assembly, and also facilitates the quick opening of the second air duct housing during maintenance, repair, or replacement without disassembling the entire air duct assembly, simplifying the product assembly and maintenance process, and improving production efficiency and user convenience.

[0068] Specifically, the first or second air duct housing is provided with a wiring channel for the wires of the airflow conveying components to pass through, providing a safe and concealed wiring channel for the power lines or control lines of electrical components such as fans, avoiding wear, short circuits or interference problems that may be caused by exposed wires, and improving the safety and reliability of electrical connections.

[0069] Optionally, in some embodiments, the support platform or arc-shaped protrusion of the first air duct housing is provided with a dedicated cable routing groove.

[0070] Specifically, the first air intake channel and / or the second exhaust channel are equipped with drain outlets, which are guided and collected through pipes or water collection boxes. This effectively drains liquids that have been condensed due to temperature differences, cleaning residues, or accidental seepage into the air duct system. It prevents moisture from accumulating inside the air duct and causing corrosion, short circuits, or performance degradation to the airflow delivery components, air duct housing, or related structures. This improves the overall durability and operational safety of the air duct system and food waste processor, and is particularly suitable for humid or condensation-prone environments.

[0071] Of course, in some embodiments, the first air intake channel is provided with a dedicated drain outlet, or the second exhaust channel is provided with a drain outlet, or both the first air intake channel and the second exhaust channel are provided with drain outlets.

[0072] Furthermore, the drain outlet is connected via pipes or a water collection box, allowing water accumulated in the duct system to be discharged to a designated location or collected centrally. This prevents liquid from flowing out randomly and contaminating the internal or external environment of the food waste processor, facilitating regular cleaning and maintenance by users, improving the product's ease of use and hygiene, and helping to maintain the stability and cleanliness of the equipment's long-term operation.

[0073] Optionally, in some embodiments, the user can directly remove the water collection box and connect the drain outlet to the sewer pipe via a pipe.

[0074] Furthermore, the second air duct housing is provided with an arc-shaped protrusion that matches the shape of part of the cover. This structure can form a good structural fit and positioning support with the arc-shaped cover, thereby enhancing the stability of the cover within the mounting cavity and preventing it from shaking or shifting during operation. In some embodiments, the arc-shaped protrusion facilitates the user to grip and lift the second air duct housing.

[0075] like Figures 12 to 14The illustration shows a food waste processor with an air duct assembly. The housing 1 includes an upper outer shell 8. The upper outer shell 8 has a first upper outer shell cavity 81 into which the food waste bin 3 extends, an upper outer shell support portion 82 supporting the food waste bin 3, a water collection groove 83 located between the upper outer shell support portion 82 and the inner wall of the upper outer shell 8, and an upper outer shell air vent 84 disposed between the first air intake channel 41 and the first upper outer shell cavity 81. The upper outer shell air vent 84 is located on the side away from the first air intake channel 41, or a first filter element is disposed between the upper outer shell air vent 84 and the first air intake channel 41. The first filter element is one of a filter screen, sponge, activated carbon, silica gel, porous ceramic, or zeolite molecular sieve. The upper outer shell 8 has a guide cavity 80 that communicates with the upper outer shell air vent 84 and engages with the first air duct housing 45. The guide cavity 80 is connected to the upper side of the first air intake channel 41 in a vertical direction.

[0076] Furthermore, as a preferred embodiment of the present invention and not a limitation thereof, the upper outer shell is provided with a first upper outer shell cavity and an upper outer shell support part, which can effectively support and position the food waste bin, so that the food waste bin is accurately positioned and firmly fixed during installation, while facilitating user pick-up and operation.

[0077] Specifically, the water collection groove located between the upper outer shell support and the inner wall of the upper outer shell can effectively collect and temporarily store liquids such as washing water and condensate that may be generated around the food waste bin, preventing liquids from flowing directly into the area below the food waste bin and causing damage to the circuit components or other internal structures in the first accommodating cavity. This avoids equipment damage, short circuits, or hygiene problems caused by such liquids, and improves the safety, durability, and hygiene performance of the product. It is especially suitable for use in humid or liquid-prone environments.

[0078] Optionally, in some embodiments, the water collection groove collects the water accumulated after steam condensation. The water enters the first air duct housing from the upper outer shell vent and is then discharged through the drain outlet. Users can clean the water collection groove with a cloth to reduce water and odor residue.

[0079] Specifically, the upper outer shell air vent is located between the first air intake channel and the first upper outer shell cavity, serving as a key inlet for airflow from the food waste cavity to the air duct assembly. Its reasonable location effectively guides gases such as moisture, odors, or water vapor generated in the food waste cavity into the subsequent airflow path. At the same time, the upper outer shell has a structure that communicates with the guide cavity, allowing airflow to be smoothly guided into the first air intake channel through the guide cavity, reducing resistance and energy loss in the airflow path, improving gas transfer efficiency, and ensuring that the gas in the food waste cavity can be efficiently and continuously discharged.

[0080] Specifically, the guide cavity is connected to the upper side of the first air intake channel in the vertical direction and forms a snap-fit ​​connection with the first air duct housing. This design not only achieves a stable assembly between the guide cavity and the first air duct housing, ensuring the sealing and connectivity of the airflow channel, but also facilitates quick assembly and disassembly of the guide cavity during assembly or maintenance without the need for additional tools.

[0081] Optionally, in some embodiments, the first filter element may be a filter screen, sponge, activated carbon, silica gel, porous ceramic, zeolite molecular sieve, etc. The first filter element can effectively filter impurities and protect the duct system and fan components.

[0082] Optionally, in some embodiments, the first filter element is located on the side of the upper housing vent away from the first air intake channel, making it convenient for the user to replace or remove it at any time.

[0083] Optionally, in some embodiments, the first filter element is located between the upper outer shell air vent and the first air intake channel. During the assembly process of the upper outer shell and the first air duct shell, the overall stability of the first filter element can be improved, and the first filter element can be prevented from sliding off the water collection groove and the upper outer shell air vent under the action of airflow.

[0084] Optionally, in some embodiments, the first filter element is a filter sponge, which can block dust and some moisture from directly entering the first air duct housing. After the user removes the filter sponge, clean water can be added from the water collection groove or the air vent on the upper housing, so that the clean water flows into the bottom pipe or water collection box for collection.

[0085] Specifically, a first filter element is provided on the side of the upper outer casing air vent away from the first air intake channel. This filter element can effectively intercept and filter solid impurities such as food residue, moisture, dust, or debris in the airflow entering the air duct system. This prevents impurities from entering the first air intake channel, the guide cavity, or the airflow conveying assembly, thus avoiding blockage, wear, or damage to the fan blades, the inner wall of the air duct, or other precision components. This improves the operational stability and service life of the air duct system and the airflow conveying assembly, while also helping to maintain the cleanliness and unobstructedness of the airflow conveying path and ensuring the continuous and efficient operation of the gas transfer function.

[0086] like Figures 12 to 14The illustration shows a food waste disposer with an air duct assembly. The upper outer shell 8 has a second upper outer shell cavity 85 communicating with the second exhaust channel 42, a filter shell 86 extending into the second upper outer shell cavity 85, a groove 87 located on one side of the filter shell 86, and an abutment end 88 supporting the filter shell 86. The outer diameter of the filter shell 86 narrows from top to bottom. The filter shell 86 includes a first filter shell 861, a second filter shell 862 detachably connected to the first filter shell 861, and a filter cavity 863 formed by the first filter shell 861 and the second filter shell 862. The first filter shell 861 and / or the second filter shell 862 have a filter shell air inlet 864 communicating with the filter cavity 863 and the second exhaust channel 42, and a filter shell air outlet 865 communicating with the outside.

[0087] Furthermore, as a preferred embodiment of the present invention and not a limitation thereof, by providing a filter housing within the cavity of the second upper outer shell and forming a filter chamber within the filter housing, the gas discharged from the second exhaust channel must pass through the filter chamber before being discharged to the outside. This effectively intercepts and removes odors, moisture, fine particles, or residual pollutants contained in the gas, significantly improving the cleanliness of the gas discharged from the food waste processor to the external environment, improving kitchen air quality, and enhancing the user experience.

[0088] Optionally, in some embodiments, the filter housing adopts a detachable upper and lower split structure or a left and right split structure, which facilitates maintenance, cleaning and replacement.

[0089] Specifically, the filter housing includes a first filter housing and a second filter housing, which are detachably connected and together form a filter chamber. The filter materials inside the filter chamber (such as activated carbon, filter screen, moisture-absorbing material, etc.) can be quickly cleaned, replaced or maintained by disassembling the filter housing without disassembling the entire outer shell or air duct assembly. This simplifies the maintenance process, reduces the difficulty of operation for users, and improves the service life of the product. At the same time, it is convenient to replace different types of filter media as needed in different usage scenarios, thereby enhancing the product's adaptability.

[0090] Specifically, the upper outer shell has a second upper outer shell cavity for accommodating the filter housing, and also has an abutment end to support and position the filter housing, ensuring that the filter housing remains stable and does not loosen after installation. The outer diameter of the filter housing gradually narrows from top to bottom, facilitating the filter housing to extend into the second upper outer shell cavity from top to bottom, and the filter housing can abut against the abutment end or be clamped to the inner wall of the second upper outer shell cavity.

[0091] Specifically, the first filter housing and / or the second filter housing are provided with a filter housing inlet hole that connects the filter chamber and the second exhaust channel, and a filter housing outlet hole that connects to the outside. This allows the gas discharged from the second exhaust channel to enter the filter chamber through the inlet hole, be filtered in the filter chamber, and then be discharged to the outside through the outlet hole. This avoids the direct discharge of unfiltered gas, ensuring the effectiveness and reliability of the filtration function. At the same time, it facilitates the optimization design of the air inlet and outlet directions, improving the filtration efficiency and the rationality of the airflow organization.

[0092] Specifically, in some embodiments, when the first filter housing and the second filter housing are of an upper and lower structure, the air inlet of the filter housing is located on the lower side of the second filter housing, and the air outlet of the filter housing is located on the upper side of the first filter housing.

[0093] Specifically, in some embodiments, when the first filter housing and the second filter housing are left and right structures, the air inlet of the filter housing can be located in the first filter housing, or in the second filter housing, or in both the first filter housing and the second filter housing. The air outlet of the filter housing can be located in the first filter housing, or in the second filter housing, or in both the first filter housing and the second filter housing.

[0094] Optionally, in some embodiments, the groove located on one side of the filter housing facilitates the user in lifting the filter housing and can also be used to assist in positioning.

[0096] The first air duct housing 45 of this utility model adopts an integral molding structure, which simplifies the production process and enhances the structural strength and sealing performance. By concentrating the gas input, output and airflow delivery components 5 inside the first air duct housing 45, the use of multiple dispersed pipes or connecting parts in the traditional technology is avoided, which greatly reduces the installation space required for the airflow delivery system. This allows the food waste processor to achieve efficient gas transfer function even with a limited overall volume, improving space utilization efficiency and product design compactness.
