Description

Technical Field

[0001] This utility model belongs to the field of waste treatment technology, specifically relating to a kitchen waste processor. Background Technology

[0002] The grinding chamber of a food waste disposer is used to hold and grind waste. Through a built-in high-speed rotating blade or other types of crushing device, food scraps and other food waste are cut into small particles for easy disposal and processing. Specific examples include the structures disclosed in Chinese Utility Model Patent Application No. 202320967186.2, "A Grinding System for a Food Waste Disposer" (Authorization Announcement No. CN219690666U), and Chinese Utility Model Patent Application No. 202421035844.5, "A Grinding Structure for a Food Waste Disposer and a Food Waste Disposer" (Authorization Announcement No. CN222435439U).

[0003] Existing food waste disposers have the following technical problems:

[0004] 1. The machine is quite noisy when it is working;

[0005] 2. When processing hard and sharp kitchen waste, or when processing hard kitchen waste for a long time, the machine's internal parts may wear out severely or even crack, causing the machine to leak.

[0006] 3. After processing kitchen waste, small particles of residue often adhere to the inner wall of the grinding chamber, requiring users to turn on the tap again to clean it, which reduces the user experience.

[0007] 4. The efficiency of grinding kitchen waste needs to be further improved. Utility Model Content

[0008] The technical problem to be solved by this utility model is to provide a kitchen waste disposer that improves crushing efficiency, reduces noise during operation, and prevents machine leakage, in light of the current state of the technology.

[0009] The technical solution adopted by this utility model to solve the above-mentioned technical problems is: a kitchen waste disposer, comprising:

[0010] The machine casing has a hollow interior forming a cavity, with an inlet and an outlet respectively located at the upper and lower parts of the cavity;

[0011] The crushing component is located inside the housing and can rotate circumferentially relative to the side wall of the cavity under the drive of the drive mechanism to crush the kitchen waste entering from the feed inlet.

[0012] Its characteristic is that it also includes:

[0013] A cylindrical liner is vertically positioned within the cavity, and the liner's peripheral wall forms a vertically penetrating channel for food waste to pass through. The liner's peripheral wall has a first portion at the top and a second portion at the bottom. The outer peripheral surface of the second portion is adjacent to or abuts against the sidewall of the corresponding cavity. The inner peripheral surface of the second portion is provided with at least two protrusions spaced circumferentially, each protrusion located above the pulverizer. The outer peripheral surface of the first portion and the sidewall of the corresponding cavity are arranged at intervals to form an annular cavity. The sidewall of the cavity is provided with an inlet for water to enter the annular cavity, and the first portion is provided with an outlet for water to exit the annular cavity.

[0014] The inner liner in this invention allows for automatic water intake when the machine processes food waste, filling the annular cavity with water in a dynamic flow state, thus providing sound insulation and noise reduction. Simultaneously, the liner acts as a barrier between the grinding components and the side wall of the casing, preventing wear on the casing wall when processing hard, sharp food waste, especially during prolonged processing. Even if the liner is worn by sharp food waste or develops cracks leading to leakage, the leakage will only occur within the casing cavity and will not cause a complete machine leak. Therefore, the liner enhances the overall structural strength of the food waste processor. Furthermore, the protrusions on the liner act as a turbulence buffer, preventing food waste from rotating circumferentially with the grinding components, thereby improving grinding efficiency.

[0015] Preferably, the diameter of the first portion of the peripheral wall is smaller than the diameter of the second portion. This facilitates the falling of kitchen waste while also preventing it from splashing upwards during the crushing process.

[0016] Preferably, the lining has an upwardly extending first circumferential wall, a second circumferential wall that extends upward from the upper edge of the first circumferential wall and gradually slopes towards the center, and a third circumferential wall that extends upward from the upper edge of the second circumferential wall.

[0017] The first part of the peripheral wall includes the aforementioned third peripheral wall, and the second part of the peripheral wall includes the aforementioned first peripheral wall.

[0018] Preferably, the upper part of the third peripheral wall and the second peripheral wall constitutes the first part of the peripheral wall, and the lower part of the second peripheral wall and the first peripheral wall constitute the second part of the peripheral wall.

[0019] Furthermore, the protrusions on the first peripheral wall extend upwards to and engage with the second peripheral wall. These protrusions not only improve crushing efficiency but also act as "reinforcing ribs," enhancing the strength of the lining structure.

[0020] In the above embodiments, preferably, a grinding ring is also included, which is disposed circumferentially inside the cavity and below the liner;

[0021] The lower end face of the liner's peripheral wall is supported on the grinding ring, and the upper end face of the liner's peripheral wall is in contact with the corresponding side wall of the cavity. This allows the liner to be confined within the cavity, and screws or other connecting components are required.

[0022] Preferably, the lower edge of the peripheral wall of the lining is folded back and extended outward to form a retaining edge;

[0023] It also includes a lower sealing ring, which is fitted around the outer periphery of the baffle, and the cross-section of the lower sealing ring is a transverse U-shape with an opening for the baffle to be inserted. The outer surface of the lower sealing ring contacts the side wall of the corresponding cavity and the upper end face of the grinding ring.

[0024] The fit between the lower sealing ring and the flange notch not only achieves sealing but also reduces vibration, slowing down the transmission of vibration during the operation of the crushing parts.

[0025] To constrain the lining circumferentially, preferably, the upper end face of the lining's circumferential wall and the corresponding side wall of the cavity are respectively provided with interlocking positioning protrusions and grooves, and the interlocking positioning protrusions and grooves are arranged as a group, with at least two groups, and spaced apart circumferentially. This prevents the lining from rotating circumferentially.

[0026] Furthermore, an upper sealing ring is provided between the upper end face of the peripheral wall of the liner and the side wall of the corresponding cavity, and the upper sealing ring is located around each set of positioning protrusions and grooves. The sealing ring can prevent water leakage between the upper end face of the peripheral wall of the liner and the side wall of the corresponding cavity.

[0027] Preferably, the crushing component is a grinding disc, which can rotate around its central vertical axis under the drive of the driving mechanism.

[0028] Compared with existing technologies, the advantages of this invention are as follows: The inner liner automatically introduces water when the machine processes food waste, filling the annular cavity with water. The water flow within the cavity is dynamic, providing sound insulation and noise reduction. Simultaneously, the liner acts as a barrier between the grinding components and the side wall of the casing, preventing wear on the casing wall when processing hard, sharp food waste, especially during prolonged processing. Even if the liner is worn by sharp food waste or develops cracks leading to leakage, the leakage will only occur within the casing cavity and will not cause overall machine leakage. Therefore, the liner enhances the overall structural strength of the food waste processor. Furthermore, the protrusions on the liner act as a turbulence buffer, preventing food waste from rotating circumferentially with the grinding components and improving grinding efficiency.

[0035] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0036] like Figures 1-6 As shown, this is a preferred embodiment of a food waste disposer of the present invention. The food waste disposer includes a shell 1, a crushing component 2, a driving mechanism 3, an inner liner 4, a grinding ring 5, a lower sealing ring 6, and an upper sealing ring 7.

[0037] The machine casing 1 has a hollow cavity 10 inside. The top of the cavity 10 is provided with a feed inlet 1a, and the lower side wall of the cavity 10 is provided with a discharge outlet 1b.

[0038] The grinding ring 5 is existing technology, and it is disposed circumferentially in the cavity 10.

[0039] The crushing component 2 is an existing grinding disc that cooperates with the grinding ring 5. Under the drive of the drive mechanism 3 (which is an existing motor), the grinding disc can rotate around its central vertical axis relative to the grinding ring 5 to crush the kitchen waste that enters from the feed inlet 1a.

[0040] A cylindrical liner 4 is vertically disposed within the cavity 10, and the peripheral wall of the liner 4 forms a vertically penetrating channel 40 for food waste to pass through. Simultaneously, the peripheral wall of the liner 4 has a first part 4a located at the top and a second part 4b located at the bottom. The diameter of the first part 4a is smaller than the diameter of the second part 4b. The outer peripheral surface of the second part 4b is in contact with the corresponding side wall of the cavity 10. The outer peripheral surface of the first part 4a and the corresponding side wall of the cavity 10 are arranged at intervals to form an annular cavity 400. The side wall of the cavity 10 is provided with an inlet 11 for water to enter the annular cavity 400. The first part 4a is provided with an outlet 401 for water to be output from the annular cavity 400. Each outlet 401 is radially inclined relative to the annular cavity 400 so that each outlet 401 is arranged in a clockwise or counterclockwise rotation direction, so that the water flow can be sprayed out from each outlet 401 in a rotating posture and clean the wall surface near the outlet. In this embodiment, the lining 4 has an upwardly extending first circumferential wall 41, a second circumferential wall 42 extending upward from the upper edge of the first circumferential wall 41 and gradually inclined towards the center, and a third circumferential wall 43 (which may also extend vertically upward) extending upward from the upper edge of the second circumferential wall 42 and gradually inclined towards the center. The angle between the third circumferential wall 43 and the horizontal plane is greater than the angle between the second circumferential wall 42 and the horizontal plane. The upper part of the third circumferential wall 43 and the second circumferential wall 42 constitutes the first part 4a of the aforementioned circumferential wall, and the lower part of the second circumferential wall 42 and the first circumferential wall 41 constitute the second part 4b of the aforementioned circumferential wall. Meanwhile, the inner circumferential surface of the first circumferential wall is provided with a plurality of protrusions 410 spaced circumferentially, each protrusion 410 extending upward to the second circumferential wall 42 and engaging with it. Each protrusion 410 is located above the crushing component 2.

[0041] To stably confine the liner within the cavity, the lower edge of the first peripheral wall 41 is folded back and extended outward to form a retaining edge 44. The retaining edge 44 is supported on the upper end face of the grinding ring 5. The lower sealing ring 6 is fitted around the outer periphery of the retaining edge 44, and the cross-section of the lower sealing ring 6 is a transverse U-shape with an opening for the retaining edge 44 to be inserted. The outer surface of the lower sealing ring 6 contacts the side wall of the corresponding cavity 10 and the upper end face of the grinding ring 5. The upper edge of the third peripheral wall 43 is folded back and extended outward to form a flange. The upper end face of the flange fits against the side wall of the corresponding cavity 10, and the upper end face of the flange is provided with multiple positioning protrusions 45 spaced circumferentially. The side wall of the cavity 10 that fits against the upper end face of the flange is provided with grooves 12 for the corresponding top protrusions 45 to be inserted. The engagement of the positioning protrusions 45 and the grooves 12 can prevent the liner from rotating circumferentially. Meanwhile, the side wall of the cavity 10 that fits against the upper end face of the flange is provided with an annular groove for the upper sealing ring 7 to be installed. The upper sealing ring 7 is located around each set of positioning protrusions 45 and grooves 12.

[0042] In the specification and claims of this utility model, terms indicating direction, such as "upper," "lower," "side," "top," and "bottom," are used to describe various exemplary structural parts and elements of this utility model. However, the use of these terms is merely for the purpose of convenience of description and is based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed in this utility model can be arranged in different orientations, these terms indicating direction are for illustrative purposes only and should not be regarded as limitations. For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity.

[0043] The term "vertical" is also used in the specification and claims of this utility model, meaning basically along the up and down direction, and is not limited to just the vertical direction, but can also be slightly deviated from the vertical direction.
