Description

Technical Field

[0001] The utility model belongs to the technical field of garbage disposal, and in particular relates to a grinding disc assembly for a kitchen waste disposer and a kitchen waste disposer. Background Art

[0002] At present, there are many types of grinding system designs for food waste disposers on the market, but their structures are generally similar. They are all based on grinding discs and grinding rings with grinding hammers, and have been improved and optimized in different directions to improve the grinding effect and speed of food waste.

[0003] For example, the Chinese utility model patent "A grinding system for a kitchen waste disposer" with patent number 202320967186.2 and authorization announcement number CN219690666U includes a grinding cover with a grinding ring and a grinding disc installed in the grinding cover. The grinding disc rotates relative to the grinding ring under the drive of a driving mechanism. A grinding disc is fixed to the bottom of the grinding disc. A first curved portion with an opening facing upward is formed on the outer periphery of the grinding disc. The first curved portion extends outward from the outer edge of the grinding disc. The lower part of the grinding ring extends into the first curved portion with a gap left. A first blanking hole is opened on the first curved portion, thereby increasing the grinding area and effectively improving the grinding effect.

[0004] When the existing grinding system is in operation, if it encounters too hard kitchen waste, such as bones, etc., it may get stuck and the grinding disc may not rotate, thus affecting its use. Utility Model Content

[0005] The first technical problem to be solved by the present invention is to provide a grinding disc assembly for a food waste disposer in view of the current status of the prior art, so as to improve the grinding effect and avoid the phenomenon of jamming during grinding.

[0006] The second technical problem to be solved by the present utility model is to provide a kitchen waste disposer having the above-mentioned grinding disc assembly.

[0007] The technical solution adopted by the utility model to solve the above-mentioned first technical problem is: a grinding disc assembly for a kitchen waste disposer, comprising:

[0008] The grinding disc body can rotate forward or reverse around its own axis extending up and down under the action of the driving mechanism;

[0009] It is characterized by also including:

[0010] At least two movable teeth are constrained to the grinding disc body at intervals around the axis, and each movable tooth is arranged in a manner that it can rotate around its corresponding rotating shaft extending up and down, and when the grinding disc body rotates forward, each movable tooth rotates outward under the action of centrifugal force so that at least the head of the movable tooth is located at the periphery of the grinding disc body, and when the grinding disc body is reversed, each movable tooth rotates inward and closes.

[0011] In this way, when the driving mechanism drives the grinding disc body to rotate forward, under the action of centrifugal force, each movable tooth rotates outward until at least the head of the movable tooth is located at the periphery of the grinding disc body, so that it can hit and tear the kitchen waste and effectively crush the kitchen waste; on the contrary, when the kitchen waste is too hard and the grinding disc body is stuck in the forward rotation, the driving mechanism drives the grinding disc body to reverse, at which time, each movable tooth rotates inward and closes to help the grinding disc body get out of trouble. At the same time, when the grinding disc body reverses, by intermittently controlling the rotation speed of the grinding disc body, each movable tooth can also play a mobile crushing role.

[0012] The forward and reverse rotations of the grinding disc body are relative directions. For example, when the clockwise direction is the forward rotation direction, the counterclockwise direction is the reverse rotation direction; when the counterclockwise direction is the forward rotation direction, the clockwise direction is the reverse rotation direction.

[0013] Preferably, each movable tooth is disposed on the bottom surface of the grinding disc body and is disposed adjacent to the edge of the bottom surface.

[0014] Preferably, the rotating shaft is arranged at the center of the movable tooth, relatively close to the tail of the movable tooth, and relatively far away from the head of the movable tooth.

[0015] Furthermore, a through hole is provided in the center of the movable tooth, and the rotating shaft is the rod of a screw, which passes through the through hole upwards and is connected to the grinding disc body to constrain the movable tooth to the grinding disc body. In this way, the screw can connect the movable tooth to the grinding disc body, and the rod of the screw serves as a rotating shaft for the movable tooth to rotate around.

[0016] In the above scheme, preferably, the bottom surface of the grinding disc body is provided with a position corresponding to each movable tooth, and the limiter is arranged so that the heads of each movable tooth in the folded state are arranged in a first rotation direction clockwise or counterclockwise as a whole, and when the grinding disc body rotates forward, each movable tooth rotates in a second rotation direction opposite to the first rotation direction until it is constrained by the limiter and arranged in the second rotation direction as a whole. In this way, the rotation of the movable teeth can be controlled by the forward and reverse rotation of the grinding disc body.

[0017] Preferably, the limiting member includes a radially extending limiting strip, and in the folded state, the limiting strip is located on the first rotation direction side of the corresponding movable tooth, and the outer end of the limiting strip is opposite to the movable tooth to limit the movable tooth from further rotating along the first rotation direction;

[0018] When the grinding disc body rotates forward, the movable tooth rotates along the second rotation direction until the tail of the movable tooth abuts against the limit bar.

[0019] Preferably, the grinding disc body comprises:

[0020] A grinding disc body, which can rotate forward or reverse around its own axis extending up and down under the action of a driving mechanism, and the bottom surface of the grinding disc body is the bottom surface of the above-mentioned grinding disc main body;

[0021] The grinding hammer is arranged on the top surface of the grinding disc body.

[0022] In the above-mentioned schemes, preferably, when the grinding disc body rotates forward, the windward surface of each movable tooth is a blade surface with cutting function.

[0023] In this way, when the grinding disc body rotates forward, each movable tooth can cut the kitchen waste.

[0024] Preferably, the blade surface is wedge-shaped and extends in the inward and outward directions. The wedge-shaped blade has a better cutting effect on long fibers. For those large and hard garbage, the wedge-shaped blade has a better effect than the blunt surface.

[0025] The technical solution adopted by the utility model to solve the above-mentioned second technical problem is: a kitchen waste disposer, characterized by having the grinding disc assembly as described above.

[0026] Preferably, the food waste disposer also includes:

[0027] A grinding cover having a grinding cavity inside for the grinding disc body and movable teeth to be arranged therein;

[0028] The grinding ring is located in the grinding cover, is circumferentially arranged on the periphery of the grinding disc body and the movable teeth, and is fixed relative to the grinding cover.

[0029] Compared with the prior art, the utility model has the following advantages: when the driving mechanism drives the grinding disc body to rotate forward, under the action of centrifugal force, each movable tooth rotates outward until at least the head of the movable tooth is located at the periphery of the grinding disc body, so that it can hit and tear the kitchen waste and effectively crush the kitchen waste; on the contrary, when the kitchen waste is too hard and the grinding disc body is stuck in the forward rotation, the driving mechanism drives the grinding disc body to reverse, at which time, each movable tooth rotates inward and closes to help the grinding disc body get out of trouble. At the same time, when the grinding disc body reverses, by intermittently controlling the rotation speed of the grinding disc body, each movable tooth can also play a mobile crushing role.

[0036] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0037] like Figures 1 to 6 As shown, a preferred embodiment of the grinding disc assembly for a food waste disposer and the food waste disposer of the utility model is shown, and the food waste disposer includes a grinding cover 3, a grinding ring 4 and a grinding disc assembly.

[0038] The grinding cover 3 has a grinding chamber 30 therein, the top wall of the grinding chamber 30 is provided with a feed inlet 30a, and the lower part of the side wall is provided with a discharge port 30b.

[0039] The grinding ring 4 is a prior art, which is arranged in the grinding chamber 30 and fixed relative to the grinding chamber 30. The side wall of the grinding ring 4 is provided with a protrusion for grinding.

[0040] The grinding disc assembly is disposed in the grinding chamber 30 and the inner periphery of the grinding ring 4 , and includes a grinding disc body 1 and at least two movable teeth 2 .

[0041] The grinding disc body 1 includes a grinding disc body 12 and a grinding hammer 13. The grinding disc body 12 can rotate forward or reversely around its own vertically extending axis 10 under the action of a driving mechanism (a motor), and the bottom surface of the grinding disc body 12 is provided with radially extending limit bars 11 at intervals along the circumferential direction, and the outer end of each limit bar 11 is arranged adjacent to the edge of the bottom surface of the grinding disc body 12. The grinding hammer 13 is an existing structure and is arranged on the top surface of the grinding disc body 12 so as to rotate with the grinding disc body 12. Each movable tooth 2 is constrained to the bottom surface of the grinding disc body 12 at intervals around the axis 10 and is located between two corresponding adjacent limit bars 11, and each movable tooth 2 is arranged in a manner that it can rotate around a corresponding vertically extending rotating shaft 20, and when the grinding disc body 12 rotates forward, each movable tooth 2 rotates outward under the action of centrifugal force so that the head 21 of the movable tooth 2 is located at the periphery of the edge of the grinding disc body 12, and when the grinding disc body 12 is reversed, each movable tooth 2 rotates inward and closes. In the folded state, the head 21 of each movable tooth 2 is arranged in a first rotation direction clockwise or counterclockwise as a whole, and each movable tooth 2 cannot further rotate along the first rotation direction under the action of the limiting strip 11 on the first rotation direction side corresponding to each movable tooth 2 (such as Figure 3 As shown, the first rotation direction is counterclockwise. When the grinding disc body 1 rotates forward, each movable tooth 2 rotates in a second rotation direction opposite to the first rotation direction until it is constrained by the limiting strip 11 on the first rotation direction side corresponding to each other and the head 21 is arranged in the second rotation direction as a whole (as shown in FIG. Figure 6 As shown, the second rotation direction is clockwise). When the grinding disc body 1 rotates forward, the windward surface of the head 21 of each movable tooth 2 is a blade surface 23 with a cutting function. The blade surface 23 is wedge-shaped and extends inward and outward directions.

[0042] In this embodiment, a through hole 200 is provided in the center of each movable tooth 2, which is relatively close to the tail 22 of the movable tooth 2 and relatively far from the head 21 of the movable tooth 2. The rotating shaft 20 is a rod of a screw, which passes through the through hole 200 upwards and is connected to the grinding disc body 12 to constrain the movable tooth 2 to the grinding disc body 12.

[0043] In this way, when the driving mechanism drives the grinding disc body 12 to rotate forward, the grinding disc body 12 and the grinding hammer 13 thereon cooperate with the grinding ring 4 to grind the processed garbage, and under the action of centrifugal force, each movable tooth 2 rotates outward until the head 21 of the movable tooth 2 is located at the periphery of the grinding disc body 12, so that it can hit, tear, and cut the kitchen waste to achieve the effect of crushing the kitchen waste and improve the waste treatment effect; on the contrary, when the kitchen waste is too hard and the grinding disc body 12 is stuck in the forward rotation, the driving mechanism drives the grinding disc body 12 to reverse, at which time, each movable tooth 2 rotates inward and closes to help the grinding disc body 12 get out of trouble. At the same time, when the grinding disc body 12 reverses, by intermittently controlling the rotation speed of the grinding disc body 12, each movable tooth 2 can also play a mobile crushing role.

[0044] The term "radial" is used in the specification and claims of the present utility model, which means basically along the inward and outward direction, and is not limited to the radial direction passing through the center of the circle, and can also be slightly deviated from the radial direction.
