Description

Technical Field

[0001] This invention relates to an integrated device for treating kitchen waste, belonging to the technical field of kitchen equipment. Background Technology

[0002] Food waste, with its high moisture content, is highly susceptible to decay and spoilage. During storage, it continuously breeds bacteria, attracts pests, and produces a pungent odor, leading to unpleasant conditions in and around garbage bins. Existing disposal methods have multiple drawbacks: In households, frequent handling and scooping of waste by hand is not only unpleasant but also poses hygiene risks. During waste packaging, leachate leakage and odor release can cause strong sensory discomfort. If ordinary garbage disposers are used to directly pulverize and discharge food waste into the sewer system, the high moisture content of the food waste increases the load on the sewage treatment system, and the grease and solid particles easily adhere to the pipe walls, significantly increasing the risk of blockages. Furthermore, traditional wet waste collection and transportation is prone to spillage and odor spread, while landfill or incineration generates leachate pollution and greenhouse gas emissions, increasing social and environmental costs. These problems collectively make food waste disposal a challenge for household hygiene and urban environmental management, urgently requiring an integrated solution that can achieve source reduction, harmless treatment, and avoid secondary pollution. Summary of the Invention

[0003] The purpose of this invention is to provide an integrated device for kitchen waste treatment, so as to solve the problems of easy bacterial growth, strong odor, need for manual contact, and easy blockage of pipes in traditional kitchen waste treatment.

[0004] The present invention is achieved through the following technical solution.

[0005] An integrated kitchen waste treatment device includes a water filter assembly connected to the drain of a kitchen sink and a drying and grinding assembly located below the water filter assembly.

[0006] The water filtration assembly includes a filter cylinder with filter holes arranged on its wall, and a valve that can be opened and closed located at the bottom of the filter cylinder. The top opening of the filter cylinder is connected to the drain and is used to receive kitchen waste. Its filter holes are used to filter out the moisture from the kitchen waste.

[0007] The drying and grinding assembly includes a food waste processing bin, a grinding mechanism, and a drying mechanism. The top of the food waste processing bin is open to receive food waste falling from the filter cartridge. The grinding mechanism is located inside the food waste bin to grind and pulverize the food waste. The drying mechanism is used to heat and dry the food waste during the pulverization process.

[0008] As a further improvement of the present invention, a housing is provided outside the filter cylinder, there is a gap between the housing and the filter cylinder, and an annular drainage channel is formed. The housing is connected to a drain pipe for discharging the water filtered out by the filter cylinder.

[0009] As a further improvement of the present invention, the valve includes two valve plates that are rotatably configured to open and close the valve. The top surfaces of the two valve plates are respectively provided with two connecting grooves. When the valve is closed, the two connecting grooves are combined to form a circular locking groove. Two valve cores that can rotate around the center of the locking groove and are symmetrically arranged are provided in the locking groove. This is suitable so that the valve is in a closed state when both valve cores cross the two connecting grooves, and the valve is in an open state when the two valve cores are respectively located in a single connecting groove.

[0010] As a further improvement of the present invention, the grinding mechanism includes a drive motor disposed outside the bottom of the food waste processing compartment, and a grinding blade assembly located at the bottom of the food waste processing compartment and driven to rotate by the drive motor.

[0011] As a further improvement of the present invention, it also includes a hot air circulation mechanism, which includes an air inlet chamber disposed outside the food waste treatment chamber, an exhaust fan disposed inside the air inlet chamber, and an exhaust duct. The heating mechanism is disposed inside the air inlet chamber, the air inlet chamber forms a hot air inlet on the wall of the food waste treatment chamber, and the exhaust duct forms an odor exhaust outlet on the wall of the food waste treatment chamber.

[0012] As a further improvement of the present invention, the heating mechanism is configured as a PTC heating module, and the PTC heating module is disposed on the cavity wall of the air inlet cavity near the food waste treatment compartment.

[0013] As a further improvement of the present invention, both the hot air inlet and the hot air outlet extend in a horizontal direction, the horizontal height of the hot air inlet is lower than that of the odor exhaust outlet, and its air outlet direction is directly opposite to the grinding mechanism.

[0014] As a further improvement of the present invention, an odor-removing filter element is provided inside the exhaust duct, and the filter element fills at least one cross-section of the exhaust duct.

[0015] As a further improvement of the present invention, the food waste processing compartment is constructed as a pull-out structure for removing and processing the dried powder formed therefrom.

[0016] As a further improvement of the present invention, a pull-out structure is provided on the outer wall of the food waste treatment compartment for manual pulling out of the food waste treatment compartment.

[0017] The beneficial effects of this invention are:

[0018] Through the synergistic design of the filtration and drying / grinding components, the filter cartridge first achieves preliminary solid-liquid separation of kitchen waste using its filter holes. The filtered water is discharged independently through a ring-shaped drainage path, avoiding sewage backflow and electrical safety hazards. A bottom-mounted, openable valve dynamically controls the timing of waste descent, ensuring sealed storage during the draining stage and precise disposal during the processing stage. In the drying / grinding component, the grinding mechanism rotates at high speed driven by a motor, shearing and pulverizing the waste. Simultaneously, the drying mechanism continuously provides heat, dehydrating and drying the wet waste during the pulverization process. This dual dehydration design significantly reduces the moisture content of the waste, producing a dry powdery output. This reduced volume and eliminates the source of decay, preventing the foul odors and leachate produced by wet waste fermentation, solving the problems of bacteria growth and pest attraction associated with traditional garbage bins, and preventing sewer blockages caused by direct discharge of high-humidity waste, thus reducing the burden on sewage treatment. Furthermore, the dried powder is easy to collect and store, and can be directly used as organic fertilizer for secondary use, achieving the reduction, harmlessness, and resource recovery of kitchen waste. The entire process requires no manual contact with the waste, avoiding the hygiene risks of manually handling waste and the odor problems associated with packaging. Attached Figure Description

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0026] The directional terms such as up, down, left, right, front, back, front, back, top, and bottom mentioned or possibly used in this specification are defined relative to the construction shown in the accompanying drawings. The terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively. These are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive.

[0027] This embodiment illustrates an integrated kitchen waste treatment device that integrates solid-liquid separation, drying, and grinding functions, aiming to solve the problems of easy bacterial growth, strong odor, need for manual contact, and easy pipe blockage during traditional kitchen waste treatment processes. (Refer to...) Figures 1-5 The device includes a water filter assembly 1 connected to the kitchen sink drain and a drying and grinding assembly 2 located below the water filter assembly 1. In specific installation and usage scenarios, the water filter assembly 1 serves as the receiving end, with its filter cylinder 11 having its top opening directly connected to the sink drain. When the user pours kitchen waste into the sink, the waste first enters the filter cylinder 11. The cylinder wall of the filter cylinder 11 is arranged with dense filter holes, which can quickly filter out the liquid water in the waste under natural accumulation or slight compression, achieving preliminary solid-liquid separation. The openable and closable valve 12 at the bottom of the filter cylinder 11 serves to dynamically seal and control the fall of the waste. It remains closed during the waste draining stage, ensuring that the waste is temporarily stored in the cylinder; when processing is required, the valve 12 opens, and the dried waste block falls as a whole into the drying and grinding assembly 2 below. The drying and grinding assembly 2 is the core processing unit. Its food waste processing chamber 21 has an open top to catch falling waste. The grinding mechanism inside the chamber rotates at high speed driven by a motor, cutting and pulverizing large pieces of food waste. At the same time, the drying mechanism continuously supplies heat energy into the chamber, allowing the wet waste to be dehydrated and dried simultaneously during the pulverization process. The technical effect of this structural design is that, through the dual action of physical filtration and hot air drying, the moisture content of the waste is significantly reduced, resulting in a dry powdery product after grinding. This not only greatly reduces the volume but also completely eliminates the source of decay and spoilage, avoiding the foul odor and leachate produced by the fermentation of traditional wet waste in garbage cans. It also prevents the risk of pipe blockage caused by high-humidity waste being directly discharged into the sewer, achieving the pretreatment of food waste for reduction, harmlessness, and resource recovery.

[0028] In this embodiment, based on considerations of optimizing the drainage path and preventing cross-contamination of water, the water filter assembly 1 adopts a double-layer nested structure design. Specifically, an outer shell 13 is provided outside the filter cylinder 11. The outer shell 13 and the filter cylinder 11 are not solidly filled, but a gap is deliberately reserved to form a ring-shaped drainage path 14. When kitchen waste undergoes solid-liquid separation in the filter cylinder 11, the filtered water will not drip or accumulate inside the device, but will flow into this ring-shaped channel. The outer shell 13 is connected to a drain pipe 15, which is directly connected to the existing drainage pipe of the residence. This design ensures that the filtered wastewater has an independent and closed discharge channel, realizing the separation of solid and liquid paths, effectively avoiding the risk of wastewater backflow or seepage into the electrical component area, and ensuring the electrical safety of the equipment operation. At the same time, the independent drainage path design also means that even when processing a large amount of water-containing waste, the water can be drained quickly, preventing water accumulation in the sink due to filter hole blockage, ensuring the normal use function of the sink, and reflecting the safety design concept of complete water and electricity isolation.

[0029] In this embodiment, to further improve the control accuracy and sealing reliability of valve 12, valve 12 adopts a unique mechanical structure in which two valve plates 121 cooperate with rotary valve cores 123. Specifically, valve 12 includes two rotatably mounted valve plates 121, which can close or open like a gate. Two connecting grooves 122 are respectively provided on the top surface of the valve plates 121. When valve 12 is in the closed state, these two connecting grooves 122 exactly combine to form a complete circular locking groove. Within this locking groove, two valve cores 123 are symmetrically arranged and can rotate around the center of the locking groove, and the valve cores 123 are electrically driven. When valve 12 needs to be closed, the control mechanism drives the two valve cores 123 to rotate, so that they both cross the joint of the two connecting grooves 122. At this time, the valve cores 123 not only fill the grooves, but also exert a lateral limiting force on the two valve plates 121, so that valve 12 is in a tightly closed state and will not open accidentally even if there is heavy garbage above. Conversely, when garbage needs to be disposed of, the valve cores 123 rotate to be located in individual connecting grooves 122, no longer limiting the valve plates 121, and valve 12 can be opened smoothly. This mechanical interlocking structure greatly improves the durability of the device, avoids the leakage problem caused by the aging of traditional rubber sealing rings, and also makes valve 12 stable when bearing the weight of kitchen waste, preventing odor leakage due to poor sealing.

[0030] In this embodiment, considering both high-efficiency grinding and reduced energy consumption, the grinding mechanism adopts a design combining bottom drive and centrifugal cutting. The grinding mechanism includes a drive motor 221 located outside the bottom of the food waste processing chamber 21. This external design effectively isolates the humid environment from the motor body, extending the motor's service life. The motor shaft passes through the bottom sealing gasket and extends into the chamber, connecting at its end to a grinding blade assembly 222 located at the bottom of the food waste processing chamber 21. This blade assembly typically consists of multiple layers of alloy blades at different angles. Driven at high speed by the drive motor 221, the blade assembly generates a powerful centrifugal force, throwing the waste inside the chamber against the chamber wall for repeated impact and shearing. Fibrous waste such as vegetable leaves and fruit peels is cut, while hard waste such as bones and fruit pits is crushed. Since the waste has already been dried and becomes brittle, the grinding resistance is greatly reduced, allowing the motor to achieve efficient grinding with lower power, reducing the probability of jamming, and also avoiding the blade entanglement phenomenon that easily occurs with wet waste, ensuring the long-term stable operation of the equipment.

[0031] In this embodiment, to address the issues of hot air circulation and odor control during the drying process, a hot air circulation mechanism is added to the device. This mechanism includes an air inlet 231 located outside the food waste processing chamber 21, an exhaust fan (not shown in the figure) placed inside the air inlet 231, and an exhaust duct 232. The air inlet 231 has an air inlet that surrounds the heating mechanism, ensuring that the cold air is fully heated before entering the processing chamber. The exhaust fan forces airflow, creating a directional airflow. The heating mechanism, located inside the air inlet 231, converts electrical energy into heat energy to heat the flowing air. The air inlet 231 forms a hot air inlet h1 on the wall of the food waste processing chamber 21, through which hot air is injected into the chamber at a certain speed, directly acting on the grinding mechanism and the surface of the waste to accelerate moisture evaporation. The exhaust duct 232 forms an odor exhaust outlet h2 on the chamber wall, responsible for extracting the hot and humid air and odorous gases generated by the high temperature inside the chamber. This forced convection hot air circulation system is more efficient than natural heat dissipation, ensuring a uniform temperature distribution within the chamber and guaranteeing that even waste piled up in the center can be thoroughly dried. This significantly shortens the single processing cycle and improves the user experience.

[0032] In this embodiment, considering both rapid heating and energy-saving safety, the heating mechanism is preferably configured as a PTC heating module 24, which is located on the cavity wall of the air inlet chamber near the food waste processing compartment 21. The PTC positive temperature coefficient thermistor heater has automatic temperature control; when the air vent is accidentally blocked or insufficient airflow causes excessive temperature, its resistance increases sharply, automatically limiting power output and preventing overheating and fire, thus ensuring high safety. Simultaneously, the PTC heating module has high heating efficiency, rapidly reaching the set temperature after startup and delivering hot air into the processing compartment. In the scenario of grinding and drying food waste, the PTC module provides a continuous and stable high-temperature heat source, meeting the need to kill bacteria in the waste while avoiding the risk of damage from dry burning or localized overheating of traditional heating wires. It is ideally suited for installation under cabinets in compact and complex environments.

[0033] In this embodiment, to further improve heat exchange efficiency and grinding assistance, the position and direction of the hot air inlet h1 were optimized. Both hot air inlets h1 and h2 extend horizontally, forming a long strip shape. The horizontal height of the hot air inlet h1 is set lower than that of the odor exhaust vent h2. This layout utilizes the physical principle of natural rising of hot air, allowing the hot air to enter from the bottom, fully exchange heat within the chamber, and the hot air carrying water vapor naturally rises and exits from the top exhaust vent, forming an effective chimney effect. Good ventilation can be achieved without excessive wind pressure. More importantly, its exhaust direction is directly facing the grinding mechanism. This design serves two purposes: first, the high-speed airflow blows towards the rotating blade assembly, preventing fine dust particles from accumulating around the blades and acting as a self-cleaning agent; second, the hot air directly acts on the core grinding area, immediately removing the frictional heat and moisture generated during the grinding process, preventing the waste from scorching due to uneven heating, and ensuring the dryness and looseness of the final product.

[0034] In this embodiment, considering the improvement of air quality and home environment, an odor-removing filter element 233 is installed inside the exhaust duct 232, and the filter element 233 fills at least one cross-section of the exhaust duct 232. In the actual configuration of this embodiment, the filter element 233 basically occupies the space of the exhaust duct 232. Since kitchen waste produces gases containing ammonia, hydrogen sulfide, and other irritating odors during high-temperature drying and grinding, direct discharge into indoor cabinet spaces would cause serious odor pollution. Therefore, an activated carbon filter element 233 or other high-efficiency adsorption materials are installed along the path of the exhaust duct 232, especially near the exhaust outlet. When the hot and humid exhaust gas passes through the filter element 233, the odor molecules are physically adsorbed and trapped, and the purified air is then discharged from the equipment. This design effectively blocks the odor transmission path, preventing users from smelling rotten food during use, maintaining fresh kitchen air, and solving the unpleasant olfactory experience problem of traditional waste disposal methods.

[0035] In this embodiment, to facilitate user collection and disposal of processed waste, the food waste processing compartment 21 is designed as a pull-out structure. This compartment resembles a drawer and is connected to the outer casing 13 via guide rails. After the grinding and drying process is complete, and the food waste inside has turned into a dry powder, the user can pull the entire food waste processing compartment 21 out of the main body of the device, just like opening a drawer. This structural design completely changes the traditional "just dump it all" approach of garbage disposers, retaining the processed residue. Users can directly pour this small amount of dry powder into the trash can or use it directly as organic fertilizer for home gardening. Because the product is dry, it does not leak wastewater or emit odors, greatly simplifying the subsequent waste disposal process and also providing possibilities for the resource utilization of waste.

[0036] In this embodiment, a dedicated pull-out structure 211 is provided on the outer wall of the food waste disposal compartment 21. This pull-out structure 211 can be a handle, a groove, or a press-and-rebound switch mechanism located on the outer wall of the compartment. When cleaning is required, the user can easily pull out the heavy disposal compartment simply by operating the pull-out structure 211 with their hand, without the need for tools. This design detail takes into account the ease of use for female or elderly users, avoiding operational difficulties caused by the weight or jamming of the structure. It makes the final step of the entire waste disposal process—cleaning—as simple and intuitive as using a drawer, further enhancing the product's usability and user-friendliness.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
