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] Existing food waste disposers generally include a housing with an inlet and an outlet, a shredder inside the housing, and a drive mechanism for driving the shredder. The shredder, driven by the drive mechanism, can shred the food waste that enters from the inlet.
[0003] Specifically, the Chinese utility model patent "A Kitchen Waste Processor" with patent number 202221965311.8 and authorization announcement number CN218292145U includes a housing and a grinding hood. A grinding disc is installed inside the grinding hood. The grinding hood includes an upper grinding hood and a lower grinding hood. A feeding port is opened at the top of the upper grinding hood, and a discharge port is opened on the lower grinding hood. An annular wall is installed on the inner peripheral wall of the lower side of the upper grinding hood. The annular wall is located above the grinding disc, and an annular cavity is formed between the annular wall and the upper grinding hood. A water inlet connected to the annular cavity is opened on the outer peripheral wall of the upper grinding hood. A water outlet is opened on the inner wall of the annular cavity. An annular cutter that can rotate under water pressure is installed in the annular cavity.
[0004] For example, the Chinese utility model patent "A Kitchen Waste Treatment System" with patent number 202321652436.X and authorization announcement number CN220538788U includes a sink and a garbage disposal unit located below the sink. The garbage disposal unit includes a grinding chamber and a grinding disc located inside the grinding chamber. The grinding chamber has a discharge port located below the grinding disc. The bottom of the sink has a stepped structure, and the top of the stepped structure has a main feeding port with a feeding cover installed on it. The top of the grinding chamber is installed on the main feeding port.
[0005] Existing food waste disposers generally use the method of turning on the sink faucet to introduce water, which, together with the grinding component, crushes and grinds the waste, thus processing it and discharging the processed waste. Some food waste disposers also use valves such as solenoid valves to automatically introduce water into the cavity. This method of water introduction is more convenient, requires no manual operation, and automatically shuts off the water after the work is completed, saving time and effort.
[0006] After a food waste disposer processes food waste, some food residue will remain on the inner wall of the grinding chamber, which will mold and smell over time. Food waste disposers that automatically introduce water into the chamber through a valve are generally unidirectional water inlets, making it impossible to clean the chamber walls. Utility Model Content
[0007] The technical problem to be solved by this utility model is to provide a food waste disposer that can achieve self-cleaning of the cavity wall surface, in light of the current state of the technology.
[0008] The technical solution adopted by this utility model to solve the above-mentioned technical problems is: a kitchen waste disposer, comprising:
[0009] The machine casing has a grinding chamber inside, with a feed inlet at the top and a discharge outlet at the bottom, and the side wall of the grinding chamber is provided with a water inlet for external water to enter.
[0010] A shredder is disposed inside the shredding chamber and can work under the drive of the drive mechanism to shred kitchen waste entering from the feed inlet;
[0011] Its characteristic is that it also includes:
[0012] A vertical cylindrical guide is disposed within the grinding chamber in a manner that allows it to rotate around its own central axis. The upper and lower ends of the guide are respectively engaged with the side walls of the corresponding grinding chambers, forming an annular cavity with the aforementioned water inlet between the outer circumferential surface of the guide and the side wall of the corresponding grinding chamber. The guide is provided with a water outlet for water to be sprayed out of the annular cavity. At the same time, the outer circumferential surface of the guide is provided with outwardly extending blades, which are arranged to drive the guide to rotate circumferentially under the action of the water flow entering the annular cavity through the water inlet.
[0013] When water is introduced, the water flows into the annular cavity through the inlet hole and impacts the blades, causing the blades to rotate circumferentially along with the guide. The water jet from the outlet hole of the guide can effectively clean the inner wall of the cavity by sweeping it in multiple directions as the guide rotates circumferentially.
[0014] Preferably, there are at least two blades, arranged circumferentially around the periphery of the guide member; the outer end of each blade abuts the sidewall of the pulverizing chamber to divide the annular cavity into multiple chambers circumferentially. During the rotation of the guide member, each chamber is sequentially opposite to and connected to the water inlet. The water flow entering from the water inlet can sequentially impact the blades corresponding to each chamber, driving the guide member to rotate circumferentially.
[0015] Furthermore, the orientation of the water inlet is arranged at an angle to the radial direction of the corresponding guide member. In this way, the water flow entering from the water inlet can flow in the first circumferential direction relative to the guide member (clockwise or counterclockwise) to better impact the blades, driving the blades to rotate circumferentially with the guide member.
[0016] Preferably, the blades are located at the lower part of the guide member, and the water outlet is located at the upper part of the guide member.
[0017] The aforementioned water outlet can be horizontally positioned, tilted downwards, or tilted upwards; further, the water outlet is tilted upwards. The water jet from the water outlet cleans the cavity wall above the water outlet, and then flows downwards along the cavity wall to clean the cavity wall below the water outlet.
[0018] Furthermore, there are at least two water outlets arranged at circumferential intervals.
[0019] Preferably, the sidewall of the grinding chamber has a vertically extending vertical section and an inclined section extending upward from the upper end of the vertical section and inclined toward the center.
[0020] The flow guide is inclined from bottom to top towards the center, with the lower end of the flow guide being rotatably constrained in the vertical section and the upper end of the flow guide being rotatably constrained in the inclined section.
[0021] The guide vane, sloping upwards towards the center, facilitates the downward flow of food waste while preventing food residue from splashing upwards during grinding. The sidewall structure of the grinding chamber, with its vertical and inclined sections, fits well with the upper and lower ends of the guide vane to form an annular cavity.
[0022] In the above solutions, in order to enable the guide member to rotate smoothly under the impact of the water flow, preferably, the upper and lower ends of the guide member are rotatably constrained on the side wall of the crushing chamber by the first bearing and the second bearing, respectively.
[0023] Preferably, both the first bearing and the second bearing are rolling bearings.
[0024] In the above embodiments, preferably, the side wall of the pulverizing chamber is provided with an inlet for inputting cleaning fluid at the position corresponding to the annular cavity. The inlet is connected to a storage tank for storing cleaning fluid through a connecting pipe, and a pressurizing pump is provided for pumping the cleaning fluid in the storage tank to the annular cavity through the connecting pipe.
[0025] Compared with the prior art, the advantages of this utility model are as follows: the circumferentially rotating vertical cylindrical guide component allows water to enter the annular cavity formed by the guide component and the side wall of the crushing chamber through the water inlet hole when water is introduced, and impacts the blades on the guide component, causing the blades to rotate the guide component circumferentially. The water jet from the water outlet hole of the guide component can sweep the inner wall of the cavity in multiple directions as the guide component rotates circumferentially, thus achieving effective self-cleaning.

[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 food waste disposer of the present invention. The food waste disposer includes an organic shell 1, a crushing component 2, a driving mechanism 3, and a flow guide 4.
[0032] The machine casing 1 has a crushing chamber 10 inside. The top of the crushing chamber 10 has a feed inlet 10a, the lower side of the crushing chamber 10 has a discharge outlet 10b, and the upper side wall of the crushing chamber 10 is provided with a water inlet hole 10c for external water to enter.
[0033] The pulverizer 2 is located inside the pulverizing chamber 10, below the water inlet 10c and above the discharge port 10b, and can operate under the drive of the drive mechanism 3 to pulverize kitchen waste entering from the feed port 10a. In this embodiment, the pulverizer 2 is a conventional grinding disc, and the drive mechanism 3 is a conventional motor. The motor shaft extends upward and is connected to the center of the grinding disc to drive the grinding disc to rotate. The specific structure of the grinding disc and the principle of pulverizing kitchen waste are the same as in the prior art and will not be described in detail here.
[0034] like Figures 2-4 As shown, a vertical cylindrical guide member 4 is positioned inside the grinding chamber 10 and above the grinding member 2, allowing it to rotate around its central axis. The upper and lower ends of the guide member 4 are respectively engaged with the side walls of the corresponding grinding chamber 10, forming an annular cavity 40 with the aforementioned water inlet hole 10c between the outer circumferential surface of the guide member 4 and the side wall of the corresponding grinding chamber 10. The upper part of the guide member 4 is provided with a water outlet hole 40b for water to be sprayed out of the annular cavity 40. The water outlet hole 40b is inclined upward and has multiple holes, which are evenly spaced along the circumference. The outer circumferential surface of the middle part of the guide member 4 is provided with a circumferentially extending baffle 42. The outer periphery of the baffle 42 contacts the side wall of the grinding chamber 10 to divide the annular cavity 40 into upper and lower spaces. Multiple drain holes 420 are provided circumferentially spaced along the outer periphery of the baffle 42 to connect the upper and lower spaces. The lower outer circumferential surface of the guide member 4 is provided with outwardly extending blades 41. The number of blades 41 is the same as the number of drain holes 420. Each blade 41 is arranged circumferentially at intervals around the guide member 4 and is located on both sides of its corresponding drain hole 420. The outer end of each blade 41 is attached to the side wall of the crushing chamber 10 to divide the annular cavity 40 circumferentially into multiple chambers 400. Each chamber 400 is connected to the upper space of the annular cavity 40 through its corresponding drain hole 420. In this embodiment, as shown... Figure 3As shown, the orientation of the water inlet 10c is arranged at an angle α with the radial direction of the corresponding guide member 4, so that the water flow entering the chamber 400 through the water inlet 10c can impact the blades and drive the guide member 4 to rotate circumferentially (rotation direction as shown). Figure 3 (In the counterclockwise direction indicated by the middle arrow), and during the rotation of the guide member 4, each chamber 400 is sequentially opposite to and connected to the water inlet 10c, and the water entering each chamber 400 is discharged from the water outlet 40b through its respective drain hole 420 to clean the inner wall of the chamber. Furthermore, because the water outlet 40b is tilted upwards, it can rinse the inner wall of the feed inlet 10a above the water outlet 40b and the feeding cover at the feed inlet 10a.
[0035] In this embodiment, as Figure 2 As shown, the sidewall of the grinding chamber 10 has a vertically extending vertical section 11 and an inclined section 12 extending upward from the upper end of the vertical section 11 and towards the center. The guide member 4 is inclined from bottom to top towards the center. The lower end of the guide member 4 is rotatably constrained by the vertical section 11, and the upper end of the guide member 4 is rotatably constrained by the inclined section 12. In order to enable the guide member 4 to rotate smoothly, the upper and lower ends of the guide member 4 are rotatably constrained by the first bearing 5 and the second bearing 6, respectively, on the sidewall of the grinding chamber 10. The first bearing 5 and the second bearing 6 are both rolling bearings with an inner ring, an outer ring, rolling elements, and a cage. The inner ring is connected to the guide member 4, and the outer ring is connected to the sidewall of the grinding chamber 10. The inner ring and the guide member 4 can rotate circumferentially relative to the outer ring.
[0036] Meanwhile, in this embodiment, the side wall of the pulverizing chamber 10 is provided with an inlet for inputting cleaning fluid at the position corresponding to the annular cavity 40. The inlet is connected to the storage tank 7 for storing cleaning fluid through the connecting pipe 71, and a pressurizing pump is provided for pumping the cleaning fluid in the storage tank 7 to the annular cavity 40 through the connecting pipe 71.
[0037] 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.
[0038] 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.
[0039] The term "radial" is also used in the specification and claims of this utility model, meaning basically along the inside and outside direction, and is not limited to the radial direction that passes through the center of the circle, but can also be slightly deviated from the radial direction.
