Description

Technical Field

[0001] The utility model belongs to the technical field of garbage disposal, and in particular relates to a grinding structure 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 utility model is to provide a grinding structure for a kitchen waste disposer to avoid jamming in view of the current status of the prior art.

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

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

[0008] Grinding disc;

[0009] A driving mechanism, the output end of which acts on the grinding disc to drive the grinding disc to rotate around its own axis extending up and down;

[0010] It is characterized by also including:

[0011] A mounting column is vertically arranged on the upper surface of the grinding disc, and a mounting groove extending circumferentially is arranged on the side wall of the mounting column;

[0012] The grinding hammer has a first end of a rod portion constrained in the mounting groove in a manner of being movable along the circumference of the mounting groove, and a second end of the rod portion extending radially outward relative to the mounting column and connected with a hammer head.

[0013] When the machine is running, the grinding hammer can automatically move around relative to the mounting column according to the rotation speed of the grinding disc and the amount of food waste, effectively preventing the grinding hammer from being stuck by the food waste.

[0014] Preferably, the hammer head is spherical, and the hammer head 62 is in contact with or spaced from the upper surface of the grinding disc 2. The spherical hammer head can reduce the friction between it and the grinding disc, and prevent the kitchen waste from being stuck between the hammer head and the grinding disc.

[0015] Preferably, the rod portion extends in a radial direction of the hammer head.

[0016] In order to further avoid jamming, preferably, the first end of the rod is constrained in the mounting groove in a manner that it can rotate around its own axis. That is, the grinding hammer can rotate while also moving circumferentially relative to the mounting column, further preventing the grinding hammer from being jammed by kitchen waste.

[0017] In order to enable the grinding hammer to rotate and move circumferentially relative to the mounting column, the first end of the rod portion further has a sphere, and the inner wall of the mounting groove is in an arc shape that matches the spherical shape of the sphere, and the central angle of the arc is greater than 180°. When the sphere moves in the mounting groove, rolling friction is generated, the noise generated by friction is small, and damage and deformation of the mounting column can be avoided.

[0018] Furthermore, the diameter of the sphere is smaller than the diameter of the hammer head, and the sphere, the hammer head and the rod are connected as one.

[0019] In the above schemes, preferably, the assembled mounting columns and grinding hammers form a group, and there are at least two groups arranged on the grinding disc at intervals along the circumferential direction.

[0020] The technical solution adopted by the utility model to solve the second technical problem is: a kitchen waste disposer, comprising:

[0021] A grinding cover, wherein a grinding chamber is provided inside the grinding chamber, a feed inlet is provided at the upper part of the grinding chamber, and a discharge outlet is provided at the lower part of the grinding chamber;

[0022] A grinding ring, disposed in the grinding chamber;

[0023] It is characterized in that it also has the grinding structure as described above, the grinding disc is arranged in the grinding chamber and the inner periphery of the grinding ring, and can rotate circumferentially relative to the grinding ring under the action of the driving mechanism, and the hammer head of the grinding hammer cooperates with the grinding ring to crush the garbage entering from the feed port.

[0024] In order to improve the grinding effect, preferably, the side wall of the grinding chamber has a first circumferential wall extending upward, a second circumferential wall extending upward from the upper edge of the first circumferential wall and gradually inclined toward the center, and the first circumferential wall is provided with raised blocks at intervals along the circumferential direction, and the raised blocks are located above the grinding hammer and the mounting column.

[0025] There is a possibility that kitchen waste will splash upward when being processed. In the utility model, the second peripheral wall can play the role of a material pressing slope, blocking the kitchen waste splashing upward and rebounding it downward to the grinding disc for grinding; the raised block located below the second peripheral wall can effectively solve the problem of kitchen waste idling during grinding, and the raised block and the second peripheral wall can cooperate with each other to concentrate the kitchen waste together for processing, effectively improving the grinding fineness and grinding speed of the kitchen waste.

[0026] Preferably, the protruding block is in the shape of a vertically arranged strip, and the upper end of the protruding block extends to the second peripheral wall and engages with the second peripheral wall. In this way, the protruding block can effectively solve the problem of idling during grinding of kitchen waste, improve the grinding fineness and grinding speed of kitchen waste, and at the same time, the protruding block can also play the role of reinforcing ribs to improve the overall structural strength.

[0027] Compared with the prior art, the advantage of the utility model lies in that by arranging a mounting column and a grinding hammer on the upper surface of the grinding disc, when the machine is running, the grinding hammer can automatically move circumferentially relative to the mounting column according to the rotation speed of the grinding disc and the situation of kitchen waste, effectively preventing the grinding hammer from being stuck by kitchen waste.

[0034] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0035] like Figures 1 to 6 As shown, a preferred embodiment of the grinding structure for a food waste disposer and the food waste disposer of the present invention is shown. The grinding structure includes a grinding disc 2, a driving mechanism 3, a mounting column 5 and a grinding hammer 6.

[0036] The grinding disc 2 is circular and rotates around its own vertically extending axis under the action of the driving mechanism 3. In this embodiment, the driving mechanism 3 adopts an existing motor, and the rotating shaft of the motor extends upward and is bound together with the central part of the grinding disc.

[0037] like Figure 3 , 4 As shown, the mounting column 5 is vertically arranged on the upper surface of the grinding disc 2, and a mounting groove 50 extending circumferentially is arranged on the side circumferential wall of the mounting column 5. The inner wall of the mounting groove 50 is in an arc shape (i.e., C-shaped, the C-shaped opening is the notch of the mounting groove 50), and the central angle corresponding to the arc is greater than 180°.

[0038] The first end of the rod 61 of the grinding hammer 6 has a sphere 611, the size of which matches the size of the mounting groove 50, and the sphere 611 is inserted into the mounting groove 50 from the notch of the mounting groove 50, so that the sphere 611 can rotate and move along the extension direction of the mounting groove 50. The second end of the rod 61 extends radially outward relative to the mounting column 5 and is connected to a spherical hammer head 62, the center of the hammer head 62 and the center of the sphere 611 are both located on the central axis of the rod 61, and the diameter of the hammer head 62 is greater than the diameter of the sphere 611, and the sphere 611, the hammer head 62 and the rod 61 are connected as a whole. At the same time, the hammer head 62 contacts the upper surface of the grinding disc 2 or there is a gap between the two.

[0039] Furthermore, the assembled mounting columns 5 and grinding hammers 6 form a group, and there are two groups of them which are arranged on the grinding disc 2 at intervals along the circumferential direction.

[0040] Thus, when the grinding disc 2 rotates, the grinding hammer 6 moves relative to the mounting column 5 under the action of centrifugal force. The grinding hammer 6 can automatically rotate or / and move circumferentially relative to the mounting column 5 according to the rotation speed of the grinding disc 2 and the food waste situation, effectively preventing the grinding hammer from being stuck by the food waste.

[0041] The food waste disposer of this embodiment includes a grinding cover 1, a grinding ring 4 and the above-mentioned grinding structure.

[0042] like Figure 2 , 5As shown in Figures 6 and 7, the grinding cover 1 has a grinding chamber 10 inside, a feed port 10a is provided at the upper part of the grinding chamber 10, and a discharge port 10b is provided at the lower part of the grinding chamber 10. The side wall of the grinding chamber 10 has a first peripheral wall 11 extending upward, a second peripheral wall 12 extending upward from the upper edge of the first peripheral wall 11 and gradually tilting toward the center, a third peripheral wall 13 extending upward from the upper edge of the second peripheral wall 12, a fourth peripheral wall 14 extending outward from the lower edge of the first peripheral wall 11, and a fifth peripheral wall 15 extending downward from the outer edge of the fourth peripheral wall 14. The first peripheral wall 11 is provided with protruding blocks 111 at intervals along the circumferential direction. Each protruding block 111 is in the shape of a vertically arranged strip, and the upper end of each protruding block 111 extends to the second peripheral wall 12 and is engaged with the second peripheral wall 12, and the lower end of each protruding block 11 extends to the lower edge of the first peripheral wall 11. At the same time, the side surface of each protruding block 111 is a curved surface that is gradually curved along the circumferential direction, and the side surface of the protruding block 111 is inclined from bottom to top toward the middle of the grinding chamber 10, and the angle a2 between it and the horizontal plane is 80-85° (a2 can be any value between 80-85°, such as a2 is 80°, 81°, 83°, 85°, etc.). For details, please refer to Figure 6 .

[0043] The angle a1 between the second peripheral wall 12 and the horizontal plane is 45-60° (a1 can be any value between 45-60°, such as a1 is 45°, 50°, 55°, 60°, etc.). Figure 6 .

[0044] The upper edge of the third peripheral wall 13 defines a feed opening 10a of the grinding chamber 10. The third peripheral wall 13 is designed to temporarily store the kitchen waste to be processed.

[0045] like Figure 2 As shown, the grinding ring 4 is a prior art, which is arranged in the grinding chamber 10 and below the protruding block 111, and the upper end surface of the grinding ring 4 is supported below the fourth peripheral wall 14 through a vibration-damping ring, and the grinding ring 4 is circumferentially located at the inner periphery of the fifth peripheral wall 15. At this time, the lower end surface of each protruding block 111 is located above the grinding ring 4 and at the inner periphery of the grinding ring 4.

[0046] The grinding disc 2 is horizontally placed in the grinding chamber 10, the inner periphery of the grinding ring 4, and below the raised block 111, and can rotate circumferentially relative to the grinding ring 4 under the action of the driving mechanism 3. The hammer head 62 of the grinding hammer 6 cooperates with the grinding ring 4 to crush the garbage entering from the feed port 10a.

[0047] When in use, the angle and position of the grinding hammer 6 can be adjusted by controlling the rotation speed of the grinding disc 2 to fully grind the garbage and avoid the grinding hammer from getting stuck. At the same time, there is a possibility that the kitchen waste will splash upward when being processed. At this time, the second peripheral wall 12 can play the role of a material pressing slope, blocking the kitchen waste splashing upward and rebounding it downward to the grinding disc 2 for crushing; the raised block 111 located below the second peripheral wall 12 can effectively solve the problem of kitchen waste idling during grinding, and the raised block 111 and the second peripheral wall 12 can cooperate with each other to collect the kitchen waste together for processing, effectively improving the grinding fineness and grinding speed of the kitchen waste.
