Description

Technical Field

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

[0002] A household food waste disposer is a modern, environmentally friendly home appliance specifically designed to process organic waste generated in the kitchen. It works by decomposing food waste through microorganisms, stirring it, and heating it to evaporate moisture, reducing the volume of the waste or allowing it to be used as organic fertilizer for plants. However, the food waste disposer generates a large amount of gas during the drying and decomposition process. This gas not only has an unpleasant odor but may also carry bacteria and other harmful substances. If this gas is directly released into the air, it can cause secondary environmental pollution. Therefore, food waste disposers that can also handle odors have emerged on the market.

[0003] Currently, most common gas treatment methods on the market use activated carbon filtration before emission. However, during the long-term purification process, bacteria, odors, and other substances will adhere to the surface of the activated carbon. Since activated carbon cannot inhibit bacteria, it is easy for bacteria to grow in large quantities in the environment containing activated carbon. As a result, the emitted gas will still contain odors and bacteria, which is not conducive to the health and safety of users. Therefore, it is necessary to develop a food waste processor that can reduce odors and harmful substances such as bacteria in the emitted gas. Utility Model Content

[0004] Regarding the aforementioned technical problem that during prolonged purification, bacteria and odors adhere to the surface of activated carbon, and since activated carbon cannot inhibit bacteria, bacteria can easily proliferate in the environment containing the activated carbon, resulting in odors and bacteria still present in the emitted gas, which is detrimental to the health and safety of users, the technical solution adopted by this utility model to solve this problem is: An exhaust assembly includes an exhaust pipe, a drive assembly for accelerating gas flow within the exhaust pipe, an air inlet and an exhaust outlet respectively connected to the exhaust pipe, the exhaust pipe having a pretreatment module near the air inlet, a filter module near the exhaust outlet and connected to the pretreatment module, and a connecting pipe between the pretreatment module and the filter module, the pretreatment module including a pretreatment chamber, an antibacterial module located in the pretreatment chamber, and a heating module, the filter module including a third chamber and a removable and replaceable filter element located in the third chamber.

[0012] Furthermore, in some embodiments of this utility model, the direction of gas movement at the exhaust port is parallel to the direction of gas movement in the first chamber, or the direction of gas movement at the exhaust port is parallel to the direction of gas movement in the second chamber, and the direction of gas movement at the exhaust port is parallel to the direction of gas movement in the third chamber.

[0023] Figure 9 This is a schematic diagram of the filter module of this utility model. Detailed Implementation

[0024] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0025] like Figures 1 to 9 The exhaust assembly shown includes an exhaust pipe 1, a drive assembly 2 for accelerating gas flow within the exhaust pipe 1, an air inlet 3 and an exhaust outlet 4 respectively connected to the exhaust pipe 1. The exhaust pipe 1 is provided with a pretreatment module 5 near the air inlet 3, a filter module 6 near the exhaust outlet 4 and connected to the pretreatment module 5, and a connecting pipe 7 located between the pretreatment module 5 and the filter module 6. The pretreatment module 5 includes a pretreatment chamber 50, an antibacterial module 51 located in the pretreatment chamber 50, and a heating module 52. The filter module 6 includes a third chamber 60 and a removable and replaceable filter element located in the third chamber 60. This utility model, by setting up a pretreatment module and a filter module, first uses the antibacterial module and the heating module to reduce bacteria in the gas, and then uses the filter module to reduce odor, effectively solving the problems of bacterial growth and difficulty in completely removing odors in the gas treatment process of traditional food waste processors, providing users with a healthier user experience.

[0026] Furthermore, as a preferred embodiment of this utility model and not a limitation, the driving component ensures that gas can smoothly and effectively enter the exhaust pipe from the inlet, and then be discharged from the exhaust port after treatment. The removable and replaceable filter element can be replaced periodically, avoiding the problems of decreased filtration efficiency and bacterial growth after prolonged use. The pretreatment module and the filter module enable multi-stage gas purification. The pretreatment module first eliminates most bacteria and odors, and then the gas enters the filter module through the connecting pipe, where it is purified again by the removable and replaceable filter element, ensuring a high level of cleanliness and safety before discharge. The pretreatment module reduces the burden on the filter module, preventing a large number of bacteria and impurities from directly contacting the filter element, thereby extending the service life of the filter element and reducing maintenance costs and frequency.

[0027] Specifically, the antibacterial module effectively inhibits bacterial growth before the gas enters the filter module, reducing bacterial adhesion and proliferation on the activated carbon surface, thereby lowering the bacterial content in the exhaust gas. Simultaneously, the heating module increases the gas temperature, helping to disrupt the living environment of certain bacteria, accelerating the decomposition of odor molecules, and achieving more thorough odor elimination.

[0028] Optionally, in some embodiments, the gas may pass through the antibacterial module before entering the heating module.

[0029] Optionally, in some embodiments, the gas may first pass through the heating module before entering the antibacterial module.

[0030] Optionally, in some embodiments, the filter element may be an activated carbon filter cartridge, activated carbon bag, activated carbon powder, or other filter material.

[0031] like Figure 2 The exhaust assembly shown includes a pretreatment chamber 50 comprising a first chamber 501 for housing the antibacterial module 51 and a second chamber 502 for housing the heating module 52 and communicating with the first chamber 501. The antibacterial module 51 includes a UV lamp 511 extending into the first chamber 501 and an ozone release element. The first chamber 501 is located on the side near the air inlet 3. Further, as a preferred embodiment of this invention and not a limitation thereof, the UV lamp emits ultraviolet light of a specific wavelength. Ultraviolet light has a powerful destructive effect on bacteria, viruses, and other microorganisms, and can directly penetrate the cell wall of microorganisms, destroying their DNA or RNA structure, thereby achieving antibacterial and bactericidal effects.

[0032] In addition, the ozone-releasing element generates ozone in the first chamber. As a strong oxidant, ozone can rapidly react with bacteria, viruses, and other microorganisms, disrupting their biological structure and further enhancing the antibacterial effect. Furthermore, ozone can decompose odor molecules in the air, such as smoke, musty smells, and chemical odors, thereby purifying the air. The combined use of the UV lamp and the ozone-releasing element forms a dual antibacterial barrier, effectively reducing the risk of bacterial growth during the pretreatment stage.

[0033] Specifically, because the first chamber is located near the air inlet, the gas receives immediate antibacterial treatment from UV lamps and ozone before entering subsequent processing stages. This immediate treatment ensures that bacteria, viruses, and other microorganisms in the gas are effectively suppressed in the initial stage, providing cleaner gas for subsequent filtration modules. By pre-treating the gas before it enters the subsequent filtration modules, the burden on the filtration modules can be reduced, the service life of the filter elements can be extended, and maintenance costs can be lowered.

[0034] like Figure 2 The exhaust assembly shown includes a heating module 52 comprising a heating tube 521 extending into the second chamber 502 and a heating element 522 located outside the heating tube 521. The second chamber 502 is located on the side close to the connecting pipe 7. Further, as a preferred embodiment and not a limitation of this invention, the combined use of the heating tube and the heating element can create a uniform heating environment within the second chamber. The heating tube directly heats the gas; specifically, the heating element surrounds the outside of the heating tube, increasing the contact area with the gas and thus raising the temperature of the chamber wall, reducing heat loss, and ensuring that the gas is sufficiently heated as it passes through the second chamber.

[0035] Additionally, heating accelerates the evaporation of moisture in the gas, reducing humidity. For the gas produced by the food waste disposer, reduced humidity helps decrease the growth of bacteria and other microorganisms, while also improving the adsorption efficiency of subsequent filtration modules for odors and harmful substances. Heating can also alter the chemical properties of certain harmful substances in the gas to some extent, making them easier for the filter material to capture or convert into harmless substances. The second chamber is located near the connecting pipes, allowing the heated gas to enter the subsequent filtration modules directly and smoothly, reducing the gas's residence time in the pipes and avoiding condensation problems caused by temperature drops.

[0036] like Figure 2 The exhaust assembly shown has the following configuration: the first chamber 501 has a first chamber inlet 5011 and a first chamber exhaust port 5012 communicating with the inlet 3; the second chamber 502 has a second chamber inlet 5021 communicating with the first chamber exhaust port 5012 and a second chamber exhaust port 5022 communicating with the connecting pipe 7; the first chamber exhaust port 5012 is located on the side away from the inlet 3. Further, as a preferred embodiment of this utility model and not a limitation thereof, after the gas enters the first chamber through the inlet, the gas circulates fully within the first chamber, increasing the contact time between the gas and the UV lamp and ozone releasing element, thereby improving the antibacterial and odor removal effects. The gas then exits from the first chamber exhaust port into the second chamber, undergoes heating treatment by the heating tube and heating element, and is then exited from the second chamber exhaust port to the connecting pipe. The gas movement process is compactly designed, avoiding unnecessary detours and improving the efficiency of gas treatment. Meanwhile, since the exhaust port of the first chamber is located on the side away from the air inlet, the gas stays in the first chamber for a relatively long time, which is conducive to the full implementation of the antibacterial process.

[0037] like Figures 3 to 9 The exhaust assembly shown includes a third chamber 60 with a third chamber inlet 601 connected to the connecting pipe 7 and a third chamber exhaust port 602 connected to the exhaust port 4. The filter element is located between the third chamber inlet 601 and the third chamber exhaust port 602, and the drive assembly 2 is located between the third chamber exhaust port 602 and the exhaust port 4. Further, as a preferred embodiment of this utility model and not a limitation, the filter element in the third chamber can perform deep filtration of the gas flowing in from the second chamber, ensuring cleaner exhaust gas. After entering the third chamber from the connecting pipe, the gas flows directly to the filter element and then exits from the third chamber exhaust port. This linear flow path reduces gas retention and turbulence within the third chamber, improves filtration efficiency, and ensures that the gas can pass quickly and smoothly through the entire filtration module.

[0038] Alternatively, in some embodiments, the drive component may be a fan, blower, or pump.

[0039] Specifically, the drive assembly is installed between the exhaust port and the exhaust port of the third chamber, which can precisely control the speed and pressure of the gas passing through the filter element. This avoids the filtration effect from being too fast and prevents the processing efficiency from being too slow. By using an appropriate moving speed, the gas residence time in the filter element is ensured to be long enough, thereby improving the filtration effect.

[0040] like Figure 8 and Figure 9 The exhaust assembly shown includes a filter module 6 comprising a first housing 61 and a second housing 62 that enclose the third chamber 60. The first housing 61 has a first housing connecting portion 611, and the second housing 62 has a second housing mating portion 621. The first housing connecting portion 611 and the second housing mating portion 621 are connected to allow for detachable connection between the first housing 61 and the second housing 62. Furthermore, as a preferred embodiment of this invention and not a limitation thereof, the detachable connection design allows users to easily separate the first and second housings, thereby facilitating the removal and replacement of the filter element. This convenience reduces the difficulty and time cost of maintenance, improving overall usability and maintenance efficiency. During the disassembly of the first and second housings, users can simultaneously perform a thorough cleaning of the interior of the third chamber. This helps remove impurities, grease, and other contaminants accumulated during long-term use, maintaining the cleanliness and hygiene standards of the third chamber.

[0041] Furthermore, when a component in the filter module malfunctions, becomes clogged, or is damaged, the user only needs to replace the faulty component or perform individual cleaning instead of replacing the entire module. This design reduces maintenance costs and improves the economic efficiency of the filter module. The stable connection structure and reliable sealing performance ensure the sealing and stability of the third chamber during operation, helping to prevent gas leakage and contamination, and improving the overall treatment efficiency and safety of the exhaust assembly.

[0042] like Figure 2 The exhaust assembly shown includes a connecting pipe cavity 70 within the connecting pipe 7, and an antibacterial ball located within the connecting pipe cavity 70. Furthermore, as a preferred embodiment of this invention and not a limitation thereof, the growth of microorganisms often leads to corrosion and blockage of the inner wall of the connecting pipe. The use of antibacterial balls can inhibit the growth of microorganisms, reduce their erosion of the inner wall of the connecting pipe, thereby extending the service life of the connecting pipe.

[0043] Specifically, antibacterial balls possess highly efficient antibacterial and bacteriostatic properties, effectively killing or inhibiting bacteria, viruses, and other microorganisms in gases or liquids flowing through connecting pipes. Antibacterial balls can also adsorb and decompose some harmful gases, helping to reduce odor molecules in the gas, thereby further purifying the gas and improving the quality of emitted gases.

[0044] like Figures 1 to 9 The exhaust assembly shown has the following configuration: the gas moves in the first chamber 501 in a direction parallel to the gas moving in the second chamber 502, or the gas moves in the first chamber 501 in a direction parallel to the gas moving in the third chamber 60, or the gas moves in the second chamber 502 in a direction parallel to the gas moving in the third chamber 60. Furthermore, as a preferred embodiment of this invention and not a limitation thereof, the parallel movement design ensures that the gas maintains a smooth flow path through each chamber, helping to reduce airflow resistance and pressure loss, and improving gas flow efficiency. Additionally, parallel flow maximizes the residence time and contact area of ​​the gas in each processing stage, enhancing the processing effect. Moreover, the parallel-flowing gas can cover more areas within the chambers, reducing dead zones and stagnant areas, avoiding the accumulation of untreated gas, and ensuring the comprehensiveness and consistency of gas treatment.

[0045] Specifically, due to the optimized airflow path, the residence time of gas in each chamber can be more rationally distributed. Antibacterial treatment is performed in the first chamber, heating treatment in the second chamber, and filtration treatment in the third chamber; each step is fully executed, thereby improving overall processing efficiency. The connection and layout between the chambers are more compact and rational, reducing the complexity and manufacturing cost of the exhaust assembly.

[0046] like Figures 1 to 9 In the exhaust assembly shown, the direction of gas movement at the exhaust port 4 is parallel to the direction of gas movement in the first chamber 501, or the direction of gas movement at the exhaust port 4 is parallel to the direction of gas movement in the second chamber 502, and the direction of gas movement at the exhaust port 4 is parallel to the direction of gas movement in the third chamber 60. Furthermore, as a preferred embodiment of this invention and not a limitation thereof, parallel flow reduces friction and collision during gas flow, lowers the noise and vibration levels during operation of the exhaust assembly, and makes the operating environment quieter and more comfortable.

[0047] The parallel movement direction ensures the continuity of gas throughout the entire processing flow. The consistent flow of gas—entering through the inlet, passing through each chamber, and finally exiting through the outlet—helps reduce resistance and turbulence generated when the airflow changes direction, thereby improving gas flow efficiency and making the gas processing process more compact and efficient. The connections between the chambers and the outlet are also smoother, reducing unnecessary piping and bends, and lowering the complexity and manufacturing cost of the exhaust assembly.

[0048] like Figures 1 to 9 The exhaust assembly shown is for a food waste processor, including a housing 8 and the exhaust assembly as described above. The housing 8 has a food waste processing chamber 80 communicating with the air inlet 3 and a food waste processing exhaust end 81 communicating with the exhaust port 4. Furthermore, as a preferred embodiment of this utility model and not a limitation thereof, combining the exhaust assembly with the housing of the food waste processor forms a compact, modular system, which not only simplifies the installation and use process but also improves the overall performance and processing efficiency of the food waste processor.

[0049] Specifically, the food waste disposer processes food residue through a food waste processing chamber within its casing. The resulting gases are then purified through an exhaust system connected to the chamber. This design ensures that the gases are thoroughly treated before being discharged, reducing environmental pollution and protecting user health. The exhaust system is designed to ensure that the gases generated during processing can be smoothly discharged from the food waste disposer's exhaust end.

[0050] Furthermore, the modular design makes full use of the internal space of the housing, tightly integrating the food waste processing chamber and the exhaust assembly, reducing the footprint of the food waste disposer and making it suitable for the compact living spaces of modern families. By integrating the exhaust assembly into the housing, external connecting pipes and fittings are reduced, resulting in a cleaner and more aesthetically pleasing appearance for the food waste disposer. This also reduces noise and vibration, providing users with a more comfortable and quieter operating environment. The modular design simplifies maintenance and cleaning. During maintenance, users can easily access key components of the food waste processing chamber and the exhaust assembly for regular cleaning or filter replacement, thereby extending the lifespan of the food waste disposer.

[0054] The third chamber 60 is provided with a third chamber air inlet 601 connected to the connecting pipe 7 and a third chamber exhaust port 602 connected to the exhaust port 4. The filter element is located between the third chamber air inlet 601 and the third chamber exhaust port 602, and the drive assembly 2 is located between the third chamber exhaust port 602 and the exhaust port 4.

[0058] The gas moves in the direction of the exhaust port 4 parallel to the direction of the gas moving in the first chamber 501, both moving in the up-down direction.

[0059] This invention, by setting up a pretreatment module 5 and a filtration module 6, first uses an antibacterial module 51 and a heating module 52 to reduce bacteria in the gas, and then uses the filtration module 6 to reduce odors. This effectively solves the problems of bacterial growth and difficulty in completely removing odors in the gas treatment process of traditional food waste processors, providing users with a healthier user experience.
