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 internal cavity of a food waste disposer is used to hold and pulverize 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. On some machines, the water inlet for external water sources is located on the side wall of the cavity, preventing water from entering the cavity evenly. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a kitchen waste disposer that provides uniform water output and reduces operating noise, in light of the current state of the technology.

[0007] The technical solution adopted by this utility model to solve the above-mentioned technical problems is: a kitchen waste disposer, comprising:

[0008] The housing has a hollow interior forming a cavity and an annular cavity located around the periphery of the cavity sidewall. The upper and lower parts of the cavity are respectively provided with a feed inlet and a discharge outlet. The annular cavity has a water inlet hole for external water to enter, and the cavity sidewall is provided with at least two water outlet holes spaced apart circumferentially.

[0009] The shredder is located inside the cavity, below the water outlet, and can move under the drive of the drive mechanism to shred kitchen waste entering from the feed inlet.

[0010] Its features are:

[0011] The annular cavity is provided with a circumferentially extending damping ring to divide the annular cavity into a first cavity with the aforementioned water inlet hole located outside the damping ring and a second cavity with the aforementioned water outlet hole located inside the damping ring. The damping ring is provided with at least two water passage holes spaced apart circumferentially to connect the first cavity and the second cavity.

[0012] The vibration damping ring design located within the ring cavity can create five layers of physical noise reduction, reducing the outward transmission of vibration during the operation of the food waste disposer and achieving a good noise reduction effect. When water is introduced, the water source enters the first cavity through the inlet hole, then enters the second cavity through the water passage hole on the vibration damping ring, and finally enters the empty cavity through the outlet hole to participate in the food waste processing process. The vibration damping ring design with water passage hole can ensure uniform water output from the outlet hole, preventing the outlet hole near the inlet hole from outputting more water than the outlet hole further away from the inlet hole, thus ensuring uniform water output from each outlet hole.

[0013] To further improve the uniformity of water output, preferably, the water outlet holes and the water passage holes are arranged in a staggered manner.

[0014] Preferably, the water outlet is located above the water passage hole.

[0015] To balance water pressure, preferably, the diameter of a single outlet hole is smaller than the diameter of a single through hole, which is smaller than the diameter of the inlet hole.

[0016] Furthermore, the number of water outlet holes is greater than the number of water passage holes.

[0017] In the above embodiments, preferably, the upper end of the annular cavity is adjacent to the feed inlet, and the lower end of the annular cavity is adjacent to the crusher.

[0018] The inner and outer surfaces of the lower part of the damping ring are in contact with the inner wall surface of the corresponding lower part of the annular cavity;

[0019] The upper part of the damping ring and the upper part of the corresponding annular cavity form the first cavity and the second cavity mentioned above.

[0020] This further prevents noise from escaping during machine operation, improves the machine's sealing performance, prevents water leakage, and enhances the uniformity of water output from the outlet.

[0021] Preferably, the housing includes a shell and a cylindrical liner vertically disposed inside the shell, the liner and the shell forming the aforementioned annular cavity, the liner defining a portion of the aforementioned cavity, and the liner having the aforementioned water outlet hole.

[0022] Preferably, it further includes a grinding ring disposed circumferentially within the cavity; the pulverizing component is a grinding disc that cooperates with the grinding ring, and the grinding disc can rotate circumferentially relative to the grinding ring around its central vertically extending axis under the drive of the driving mechanism.

[0023] Furthermore, the grinding ring has a vertically extending ring wall located within the lower end of the liner; the grinding ring also has a bottom wall extending outward from the lower edge of the ring wall and a baffle wall extending upward from the outer edge of the bottom wall, the baffle wall being inserted into a groove on the lower end face of the liner. In this way, the grinding ring can support the liner and constrain it within the housing.

[0024] Furthermore, the lower edge of the damping ring is folded back and extends outward to form a folded edge, and the lower edge of the liner is folded back and extends outward to form a flange. The upper end face of the flange is fitted to the inner wall of the corresponding housing through the folded edge of the damping ring. This improves the sealing performance of the structure.

[0025] Compared with the prior art, the advantages of this utility model are as follows: the vibration damping ring design located in the ring cavity can generate five layers of physical noise reduction, reducing the outward transmission of vibration during the operation of the food waste processor, thus achieving a better noise reduction effect; and when water is introduced, the water source enters the first cavity through the water inlet hole, then enters the second cavity through the water passage hole on the vibration damping ring, and then enters the cavity through the water outlet hole to participate in the food waste processing process. The vibration damping ring design with water passage hole can ensure that the water outlet hole output is uniform, so that the water outlet hole outputs more water near the water inlet hole area and less water outputs water far away from the water inlet hole area, ensuring that the water outlet hole outputs water evenly.

[0030] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0031] like Figures 1-4 As shown, this is a preferred embodiment of a kitchen waste disposer of the present invention. The kitchen waste disposer includes a shell 1, a crushing component 2, a drive mechanism 20, a vibration damping ring 3, and a grinding ring 4.

[0032] The housing 1 has a hollow interior forming a cavity 10 and an annular cavity 100 located circumferentially around the periphery of the side wall of the cavity 10. The top of the cavity 10 has a feed inlet 10a, and the lower side wall of the cavity 10 has a discharge outlet 10b. The annular cavity 100 has a water inlet 10c for allowing external water to enter, and the side wall of the cavity 10 has multiple water outlets 10d spaced circumferentially.

[0033] The crushing component 2 is an existing grinding disc, which is placed horizontally inside the cavity 10 and below the annular cavity 100. It can rotate around the central vertical axis under the drive of the drive mechanism 20 (an existing motor) to crush the kitchen waste that enters from the feed inlet 10a.

[0034] The grinding ring 4 is circumferentially disposed inside the cavity 10 and around the grinding disc. The grinding ring 4 has a vertically extending ring wall 41 that cooperates with the grinding disc, a bottom wall 42 that extends outward from the lower edge of the ring wall 41, and a baffle wall 43 that extends upward from the outer edge of the bottom wall 42.

[0035] In this embodiment, the housing 1 includes a shell 11 and a cylindrical inner liner 12 vertically disposed in the upper part of the shell 11. The lower edge of the inner liner 12 is folded back and extends outward to form a flange 122, and the upper edge of the inner liner 12 is folded back and extends outward to form a retaining edge 123. The upper end face of the retaining edge 123 is in contact with the corresponding inner wall surface of the shell 11, and a sealing ring 124 is provided at the contact point between the two. The outer edge of the retaining edge 123 is in contact with the corresponding inner wall surface of the shell 11. The outer edge of the flange 122 is in contact with the corresponding inner wall surface of the shell 11. The lower end face of the flange 122 is provided with a circumferentially extending annular groove 121 for the retaining wall 43 of the grinding ring 4 to be inserted therein, so that the inner liner 12 is supported on the bottom wall 42 and the retaining wall 43 of the grinding ring 4 and is located on the periphery of the annular wall 41. At this time, the aforementioned annular cavity 100 is formed between the inner liner 12 and the upper part of the shell 11. The upper end of the annular cavity 100 is adjacent to the feed inlet 10a, and the lower end of the annular cavity 100 is located above and adjacent to the crusher 2. The inner liner 12 itself defines a portion of the aforementioned cavity 10, and the inner liner 12 is provided with the aforementioned water outlet 10d. The upper part of the shell 11 is provided with the aforementioned water inlet 10c.

[0036] The aforementioned vibration damping ring 3 is circumferentially disposed within the annular cavity 100, dividing the annular cavity 100 into a first cavity 110 located outside the vibration damping ring 3 and having the aforementioned water inlet hole 10c, and a second cavity 120 located inside the vibration damping ring 3 and having the aforementioned water outlet hole 10d. The vibration damping ring 3 is provided with a plurality of water passage holes 30 spaced circumferentially to connect the first cavity 110 and the second cavity 120. In this embodiment, the water outlet hole 10d is located above the water passage hole 30, thus staggering their vertical arrangement. Furthermore, the diameter of a single water outlet hole 10d is smaller than the diameter of a single water passage hole 30, which is smaller than the diameter of the water inlet hole 10c. The number of water outlet holes 10d is greater than the number of water passage holes 30. In this embodiment, the upper part of the vibration damping ring 3 and the corresponding upper part of the annular cavity 100 form the aforementioned first cavity 110 and second cavity 120. The inner and outer surfaces of the lower part of the vibration damping ring 3 are in contact with the inner wall surface of the lower part of the corresponding annular cavity 100. Meanwhile, the lower edge of the damping ring 3 is folded back and extended outward to form a folded edge 31, and the upper end face of the flange 122 is in contact with the inner wall of the corresponding housing 11 through the folded edge 31 of the damping ring 3.

[0037] In this embodiment, the vibration damping ring 3 located in the annular cavity 100 is designed to generate five layers of physical noise reduction (from the inside out: inner lining, liquid in the second cavity, vibration damping ring, liquid in the first cavity, and side wall of the shell), which reduces the outward transmission of vibration during the operation of the food waste processor and plays a good role in noise reduction. When water is introduced, the water source enters the first cavity 110 through the water inlet 10c, then enters the second cavity 120 through the water passage 30 on the vibration damping ring 3, and then enters the cavity 10 through the water outlet 10d to participate in the food waste processing process. The vibration damping ring 3 with water passage 30 design can ensure that the water outlet 10d is uniform, so that the water outlet 10d in the area close to the water inlet 10c has more water and the water outlet 10d in the area far from the water inlet 10c has less water, ensuring that each water outlet 10d can output water evenly.

[0038] 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 explanation 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.

[0039] 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.
