Abstract
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 cavity inside a food waste disposer is used to hold and grind waste. Through a built-in high-speed rotating blade or other type of crushing device, food scraps and other food waste are cut into small particles for easy subsequent 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 inside of the machine will 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 cavity, requiring users to turn on the faucet again to clean it, which reduces the user experience.
[0007] 4. The efficiency of grinding kitchen waste needs to be further improved.
[0008] Meanwhile, some existing food waste disposers have a flow guide inside the cavity for food waste to pass downwards. The flow guide needs to be constrained in the cavity by additional connecting parts such as screws and clips. If the connecting parts are not firm enough or are damaged by hard food waste, the flow guide is prone to shifting or loosening. Utility Model Content
[0009] The technical problem to be solved by this utility model is to provide a kitchen waste processor that improves the crushing efficiency, prevents machine leakage, and stably confines the guide component within the cavity, in light of the current state of the technology.
[0010] The technical solution adopted by this utility model to solve the above-mentioned technical problems is: a kitchen waste disposer, comprising:
[0011] The housing has a hollow interior forming a cavity, with an inlet and an outlet located at the upper and lower parts of the cavity, respectively.
[0012] A grinding ring is disposed within the cavity and has vertically extending ring walls;
[0013] The grinding disc, which works in conjunction with the grinding ring, is placed horizontally in the cavity and can rotate circumferentially relative to the ring wall of the grinding ring under the drive of the drive mechanism to crush the kitchen waste that enters from the feed inlet.
[0014] A guide tube is vertically disposed in the cavity, located above the grinding ring, and the inner side of the guide tube defines a first channel that runs vertically through the cavity for kitchen waste to pass through.
[0015] Its characteristic is that it also includes:
[0016] A vertically positioned turbulence ring is located between the grinding ring and the guide tube within the cavity. The lower end face of the turbulence ring supports the upper end face of the ring wall, and the upper end face of the turbulence ring supports the lower end face of the guide tube, causing the upper end face of the guide tube to fit against the inner wall of the corresponding cavity, thereby confining the guide tube within the cavity. Simultaneously, the inner surface of the turbulence ring defines a second channel that extends vertically and is opposite to the first channel, and at least two turbulence blocks are spaced circumferentially on the inner surface of the turbulence ring.
[0017] The design of the turbulence ring located between the grinding ring and the guide tube in this utility model has the following technical effects:
[0018] 1. Improve grinding effect: The baffle blocks on the baffle ring can play a role in turbulence, preventing food waste from rotating around the grinding disc and improving grinding efficiency;
[0019] 2. Prevent machine leakage: The presence of the baffle ring prevents food waste from hitting the side wall of the cavity, avoiding machine leakage caused by the rupture of the side wall of the cavity;
[0020] 3. Fixing the guide tube: The turbulence ring supported on the grinding ring can constrain the guide tube within the cavity without the need for additional connecting parts such as screws to fix the guide tube.
[0021] Preferably, the turbulence ring has a side wall with the aforementioned turbulence block, an upper flange extending inward from the upper edge of the side wall, and a lower flange extending outward from the lower edge of the side wall. The upper surface of the upper flange is the upper end face of the turbulence ring, and the lower surface of the lower flange is the lower end face of the turbulence ring.
[0022] Preferably, the side peripheral wall has a vertically extending first peripheral wall and a second peripheral wall that extends upward and inward from the upper edge of the first peripheral wall. The lower end of the turbulence block extends to the lower edge of the first peripheral wall, and the upper end of the turbulence block extends to the second peripheral wall and joins with the second peripheral wall. In addition to its turbulence-causing function, the turbulence block also acts as a "reinforcing rib," improving the overall structural strength of the turbulence ring.
[0023] Preferably, the upper surface of the lower flange is fitted to the inner wall of the corresponding cavity by a first sealing ring. This prevents water leakage and also reduces the transmission of vibrations from the grinding ring and grinding disc to the housing during operation.
[0024] In the above embodiments, preferably, the upper edge of the guide tube is folded back and extended outward to form an upper folded edge, and the lower edge of the guide tube is folded back and extended outward to form a lower folded edge. The upper surface of the upper folded edge is the upper end face of the guide tube, and the lower surface of the lower folded edge is the lower end face of the guide tube.
[0025] Preferably, the upper surface of the lower folded edge is in contact with the inner wall of the corresponding cavity, and a second sealing ring is provided between the lower surface of the lower folded edge and the upper end face of the turbulence ring; a third sealing ring is provided between the upper surface of the upper folded edge and the inner wall of the corresponding cavity. That is, the lower folded edge of the guide tube is constrained between the upper end face of the turbulence ring and the inner wall of the cavity, and can be stably constrained within the cavity. The design of the second and third sealing rings prevents water leakage.
[0026] Preferably, an annular cavity is formed between the outer side of the guide tube and the side wall of the corresponding cavity, the side wall of the cavity is provided with an inlet for water to enter the annular cavity, and the guide tube is provided with an outlet for water to flow from the annular cavity to the first channel.
[0027] When the machine is processing food waste, it automatically fills with water, creating a dynamic flow within the ring cavity that helps to reduce noise. Simultaneously, the water flowing out of the outlet washes away any remaining food waste from the cavity.
[0028] Preferably, the outer edge of the upper folded edge is adjacent to or abuts against the sidewall of the corresponding cavity, and the inner edge of the lower folded edge is adjacent to or abuts against the sidewall of the corresponding cavity. This forms an annular cavity and prevents the guide tube from shifting relative to the cavity sidewall.
[0029] Preferably, the flow area on the cross-section of the annular cavity gradually increases from bottom to top.
[0030] Preferably, the flow area on the cross-section of the first channel gradually increases from top to bottom.
[0031] Compared with the prior art, the advantages of this utility model are as follows: The design of the turbulence ring located between the grinding ring and the guide tube in this utility model has the following technical effects:
[0032] 1. Improve grinding effect: The baffle blocks on the baffle ring can play a role in turbulence, preventing food waste from rotating around the grinding disc and improving grinding efficiency;
[0033] 2. Prevent machine leakage: The presence of the baffle ring prevents food waste from hitting the side wall of the cavity, avoiding machine leakage caused by the rupture of the side wall of the cavity;
[0034] 3. Fixing the guide tube: The turbulence ring supported on the grinding ring can constrain the guide tube within the cavity without the need for additional connecting parts such as screws to fix the guide tube. Attached Figure Description

[0040] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.
[0041] like Figures 1-5 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 grinding ring 2, a grinding disc 3, a drive mechanism 30, a guide tube 5, a turbulence ring 5, and a first sealing ring 61, a second sealing ring 62, and a third sealing ring 63.
[0042] 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.
[0043] The grinding ring 5 is a prior art material, which is disposed circumferentially in the cavity 10 and has a vertically extending ring wall 20.
[0044] The grinding disc 3 (existing technology) that cooperates with the grinding ring 2 is placed horizontally inside the cavity 10 and inside the grinding ring 5. It can rotate circumferentially relative to the ring wall 20 of the grinding ring 2 under the drive of the drive mechanism 30 to crush the kitchen waste entering from the feed port 10a.
[0045] A baffle ring 5 is vertically positioned inside the cavity 10, above the grinding ring 2. The baffle ring 5 has a vertically extending first peripheral wall 51 and a second peripheral wall 52 extending upward and inward from the upper edge of the first peripheral wall 51. The upper edge of the second peripheral wall 52 folds backward and extends inward to form an upward flange 53, and the lower edge of the first peripheral wall 51 folds backward and extends outward to form a downward flange 54. The lower surface of the downward flange 54 is the lower end face of the baffle ring 5, supporting the upper end face of the ring wall 20. The upper surface of the downward flange 54 is fitted to the corresponding inner wall surface of the cavity 10 by a first sealing ring 61. The upper surface of the upward flange 53 is the upper end face of the baffle ring 5. Simultaneously, the inner surface of the baffle ring 5 defines a second through-channel 50, allowing kitchen waste entering from the feed inlet to pass downward and fall onto the grinding disc. Furthermore, the inner side of the turbulence ring 5 is provided with a plurality of turbulence blocks 500 spaced circumferentially. The lower end of each turbulence block 500 extends to the lower edge of the first peripheral wall 51, and the upper end of each turbulence block 500 extends to the second peripheral wall 52 and joins the second peripheral wall 52.
[0046] The guide tube 4 is vertically positioned inside the cavity 10, above the turbulence ring 5. The inner side of the guide tube 4 defines a first channel 40 that runs vertically through the cavity and is opposite to the second channel 40, allowing kitchen waste to pass through. The flow area of the first channel 40 gradually increases from top to bottom. Simultaneously, an annular cavity 400 is formed between the outer side of the guide tube 4 and the corresponding sidewall of the cavity 10. The flow area of the annular cavity 400 gradually increases from bottom to top. The sidewall of the cavity 10 is provided with an inlet 11 for water to enter the annular cavity 400, and the guide tube 4 is provided with three outlets 401 for water to flow from the annular cavity 400 into the first channel 40. These outlets 401 are spaced apart circumferentially. To confine the guide tube 4 within the cavity 10, the upper edge of the guide tube 4 is folded back and extended outward to form an upper folded edge 41, and the lower edge of the guide tube 4 is folded back and extended outward to form a lower folded edge 42. The lower surface of the lower folded edge 42 serves as the lower end face of the guide tube 4, supporting the upper end face of the turbulence ring 5, and a second sealing ring 62 is provided between them. The upper surface of the lower folded edge 42 is in contact with the inner wall surface of the corresponding cavity 10. The upper surface of the upper folded edge 41 serves as the upper end face of the guide tube 4, and is in contact with the inner wall surface of the corresponding cavity 10, with a third sealing ring 63 provided at the contact point. Simultaneously, the outer edge of the upper folded edge 41 is adjacent to or in contact with the side wall of the corresponding cavity 10, and the inner edge of the lower folded edge 42 is adjacent to or in contact with the side wall of the corresponding cavity 10, so that the position of the guide tube 4 relative to the cavity is fixed.
[0047] In this embodiment, the housing 1 is formed by connecting the upper and lower parts with screws. The grinding ring and grinding disc are constrained in the lower part of the housing 1. The guide tube and the turbulence ring can be inserted into the upper part through the bottom opening of the upper part of the housing. While the upper and lower parts of the housing 1 are connected with screws, the guide tube and the turbulence ring are fixed in the housing 1 under the action of the grinding ring, which facilitates assembly.
[0048] 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.
[0049] 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.
