Description

Technical Field

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

[0002] Existing food waste disposers generally include a casing with a feed port and a discharge port, a crushing element arranged in the casing, and a driving mechanism for driving the crushing element to work. The crushing element can crush the food waste entering from the feed port under the drive of the driving mechanism.

[0003] Specifically, the Chinese utility model patent "A kitchen waste disposer" with patent number 202221965311.8 and authorization announcement number CN218292145U includes a casing and a grinding cover, a grinding disc is installed inside the grinding cover, the grinding cover includes an upper grinding cover and a lower grinding cover, the upper grinding cover has a feeding port on the top, the lower grinding cover has a discharge port, an annular wall is installed on the inner circumferential wall of the lower side of the upper grinding cover, the annular wall is arranged above the grinding disc, an annular cavity is formed between the annular wall and the upper grinding cover, a water inlet connected to the annular cavity is opened on the outer circumferential wall of the upper grinding cover, a water outlet is opened on the inner wall of the annular cavity, and an annular cutter that can rotate under the action of water pressure is installed in the annular cavity.

[0004] Another example is the Chinese utility model patent "A kitchen waste treatment system" with patent number 202321652436.X and authorization announcement number CN220538788U, which includes a sink and a garbage disposer arranged under the sink, the garbage disposer includes a grinding chamber and a grinding disc arranged in the grinding chamber, the grinding chamber has a discharge port, and the discharge port is arranged below the grinding disc. It is characterized in that: a step structure is formed at the bottom of the sink, a main feeding port is opened at the top of the step structure, a feeding cover is installed on the main feeding port, and the top of the grinding chamber is installed on the main feeding port.

[0005] In addition to the grinding effect, the design of existing kitchen waste disposers must also consider the user experience and safety. In order to prevent garbage from splashing out from the feed port during disposal, a cover such as a feeding cover or a splash-proof cover is generally provided at the feed port. When feeding, the cover is opened to expose the feed port. After feeding, the cover is closed for garbage disposal. However, sometimes people forget to cover the cover after feeding. At this time, when the machine is running, the hand can be inserted into the garbage disposer through the feed port, and the garbage is easily splashed out from the feed port during disposal, which poses certain safety hazards.

[0006] There are two main operating modes of food waste disposers on the market: one is a continuous feeding method, where the machine is turned on and food waste is continuously fed into it for processing; the other is an intermittent feeding method, where the food waste is first fed into the waste disposer, and then the machine starts to process the waste.

[0007] For a continuous feeding food waste processor, if the cover is removed, the machine can still operate. However, during the operation, food waste such as broken bones will splash upward, posing a safety hazard. For an intermittent feeding food waste processor, due to the limited capacity of the waste processor, when there is a large amount of food waste, multiple operations are required, resulting in a poor user experience. Summary of the Invention

[0008] The first technical problem to be solved by the present invention is to provide a food waste processor according to the current situation of the prior art to improve the use safety.

[0009] The second technical problem to be solved by the present invention is to provide a food waste processor according to the current situation of the prior art, which can both feed intermittently and feed continuously in a safe manner.

[0010] The technical solution adopted by the present invention to solve the above first technical problem is as follows: A food waste processor includes:

[0011] A housing having a crushing chamber inside, an inlet at the upper part of the crushing chamber, and an outlet at the lower part of the crushing chamber;

[0012] A crushing member disposed in the crushing chamber for crushing the waste entering from the inlet;

[0013] A driving mechanism whose output end acts on the crushing member for driving the crushing member to work;

[0014] A cover disposed at the inlet of the crushing chamber to block the inlet, and the cover is arranged to be able to disengage from the inlet to open the inlet;

[0015] It is characterized in that it further includes:

[0016] A magnetic induction switch and a magnetic member, which are respectively and alternatively disposed on the housing and the cover. The magnetic induction switch is electrically connected to the driving mechanism. When the cover disengages from the inlet, the magnetic member is outside the induction area of the magnetic induction switch; when the cover is at the inlet, the magnetic member triggers the magnetic induction switch so that the driving mechanism can drive the crushing member to work.

[0017] In the present invention, the design of the magnetic member and the magnetic induction switch electrically connected to the driving mechanism ensures that only when the cover is covered at the inlet, the driving mechanism can drive the crushing member to work and crush the food waste, thus ensuring the use safety.

[0018] Preferably, the magnetic member is disposed on the cover, and the magnetic induction switch is disposed on the housing.

[0019] Preferably, the magnetic member is annular. When the cover is located at the feeding port, the magnetic member extends circumferentially relative to the feeding port, and the magnetic induction switch is disposed on one side outside the feeding port. Since the magnetic member is annular, the cover can be placed arbitrarily at the feeding port to trigger the induction switch.

[0020] Preferably, when the cover is located at the feeding port, the magnetic induction switch is located below the magnetic member.

[0021] Also preferably, there are at least two magnetic members. When the cover is located at the feeding port, the magnetic members are arranged at circumferential intervals relative to the feeding port, and the magnetic induction switch is located on one side of the periphery of each magnetic member and can be triggered by at least one of the magnetic members. In this way, the cover can be placed arbitrarily at the feeding port to trigger the induction switch.

[0022] Further, there are at least two magnetic induction switches, which are arranged at circumferential intervals. When the cover is located at the feeding port, at least one of the magnetic induction switches can be triggered by the magnetic member.

[0023] Even further, there are six magnetic members, which are arranged at equal circumferential intervals, and there are two magnetic induction switches. The included angle between the connection line of one magnetic induction switch and the corresponding center of the circle and the connection line of the other magnetic induction switch and the corresponding center of the circle is 45°.

[0024] In the above solution, preferably, each magnetic induction switch is disposed on the outer side of the housing through the same box body, and the box body is an arc extending circumferentially. A cavity for constraining each magnetic induction switch therein is provided in the box body.

[0025] In order to constrain the box body and the housing together, preferably, C-shaped sockets that can cooperate with the screws on the kitchen waste processor are provided at both ends in the extending direction of the box body for the corresponding screws to be inserted horizontally. This facilitates the assembly between the box body and the housing and does not require an additional installation structure.

[0026] To improve the structural stability and prevent the box body from accidentally detaching from the housing, preferably, a torsion spring for constraining the screw in the socket is provided at the C-shaped socket. One end of the torsion spring is located in the C-shaped socket so that the screw always has a tendency to move into the C-shaped socket.

[0027] Further, the box body is formed by butt-jointing an arc-shaped base and an upper cover from bottom to top.

[0028] Preferably, the magnetic induction switch is a reed switch; the magnetic member is a permanent magnet.

[0029] In the above solutions, for the convenience of feeding, preferably, the cover is a feeding cover, and the feeding cover includes:

[0030] An outer cover is provided at the feeding port of the crushing chamber and is arranged to be movable upward to disengage from the feeding port. A through hole penetrating up and down is provided in the center of the outer cover.

[0031] An inner cover is provided at the through hole to cover the through hole, and the inner cover is arranged to be movable upward relative to the outer cover to expose the through hole.

[0032] The magnetic member is provided on the outer cover.

[0033] When a large amount or large volume of garbage needs to be fed, the outer cover can be directly opened to expose the feeding port, and the garbage directly enters the crushing chamber of the casing through the feeding port; conversely, when the garbage is less or the volume is small, the outer cover can be covered and the inner cover can be opened, and the garbage enters the crushing chamber of the casing through the through hole in the center of the outer cover.

[0034] In addition, the feeding cover can also directly adopt an existing cover plate structure, that is, the feeding port is closed after the cover plate is covered, and the feeding port is opened after the cover plate is taken out.

[0035] Preferably, the inner cover is a plate-like body, which is provided at the through hole to close the through hole.

[0036] Or, the inner cover is a filter plate with filter holes, which is provided at the through hole to cover a part of the through hole.

[0037] To further solve the above second technical problem, preferably, the cover body is a splash-proof cover, and small holes and / or slits are provided on the splash-proof cover to communicate the crushing chamber with the outside so that the outside garbage can enter the crushing chamber through the splash-proof cover.

[0038] In this way, only when the splash-proof cover is located at the feeding port can the driving mechanism drive the crushing member to work to crush kitchen waste, thus ensuring safety. And at this time, the outside kitchen waste can enter the crushing chamber through the small holes and / or slits on the splash-proof cover to achieve safe continuous feeding; and when the splash-proof cover disengages from the feeding port, the driving mechanism stops working. At this time, the outside kitchen waste can directly enter the crushing chamber through the feeding port, thus realizing intermittent feeding.

[0039] Preferably, the small holes and / or slits on the splash-proof cover are arranged to be relatively opened under the action of the falling garbage. This is beneficial to garbage feeding, and when no garbage is fed, the small holes and slits can prevent the upward splashing garbage from passing through.

[0040] Preferably, the small holes are located in the center of the splash-proof cover, there are at least two slits and they are radially arranged on the outer periphery of the small holes, and the inner ends of the slits open at the edge of the small holes. In this way, the cooperation of the small holes and the slits is beneficial to opening under the action of the falling garbage, and the size after opening is relatively large, which is beneficial to the garbage passing through.

[0041] Further, the splash guard includes:

[0042] An annular support frame on which the magnetic induction switch or the magnetic part is provided;

[0043] A conical rubber funnel provided on the inner circumference of the support frame and provided with the above-mentioned small holes and slits.

[0044] Further, the rubber funnel has:

[0045] A bottom wall with the above-mentioned small holes in the center;

[0046] A first side wall vertically extending upward from the edge of the bottom wall, and there are at least two first side walls arranged at intervals in the circumferential direction. The first part of the above-mentioned slit extending vertically is provided in the center of each first side wall, and the second part of the above-mentioned slit extending radially is provided at the position corresponding to the first part of each slit on the outer peripheral part of the bottom wall;

[0047] A second side wall extending upward and outward obliquely from the edge of the bottom wall, and there are at least two second side walls, which are respectively located between two adjacent first side walls;

[0048] A top wall extending radially outward along the radial direction of the support frame from the upper edge of each first side wall, and each top wall has two radially extending radial edges;

[0049] A third side wall vertically extending downward from each radial edge and having its lower edge joined to the inclined edge of the corresponding second side wall. The vertical edge on the inner side of each third side wall is joined to the vertical edge of the corresponding first side wall, so that each top wall, the third side walls on both sides of the top wall, and the corresponding first side wall form a convex part, and each second side wall and the third side walls on both sides of the second side wall form a concave part.

[0050] Preferably, a first weak part extending vertically is provided in the center of the first side wall. Correspondingly, a second weak part extending radially is provided in the outer peripheral part of the bottom wall. Under the action of an external force, the first weak part and the second weak part are longitudinally disconnected to form the above-mentioned slit. In this way, during the molding and manufacturing process of the rubber funnel, the weak part can improve the overall structural stability of the rubber funnel. After molding, the weak part can be longitudinally disconnected, which is convenient for operation.

[0051] Preferably, the first weak part is a first strip-shaped groove opened on the first side wall, and the second weak part is a second strip-shaped groove opened on the bottom wall. After the rubber funnel is molded, tools such as scissors can be used to cut along the second strip-shaped groove and the first strip-shaped groove, which is convenient for operation. In addition, the weak part in the present invention can also adopt small holes arranged at intervals similar to perforations, or other forms.

[0052] For the convenience of taking and placing the splash guard, preferably, a handle is convexly provided on the upper end surface of the support frame.

[0053] Preferably, a circumferentially extending annular groove is provided on the outer circumferential wall of the support frame, and a sealing ring is provided in the annular groove;

[0054] When the splash-proof cover is located at the feed inlet, the side circumferential surface of the sealing ring is attached to the inner wall of the feed inlet.

[0055] Preferably, the interior of the support frame has a circumferentially extending annular cavity for the magnetic induction switch or the magnetic member to be disposed therein.

[0056] Compared with the prior art, the advantages of the present utility model are as follows: In the present utility model, the design of the magnetic member and the magnetic induction switch electrically connected to the driving mechanism enables the driving mechanism to drive the crushing member to work and crush kitchen waste only when the cover body is covered at the feed inlet, thereby ensuring the use safety.

[0079] The present utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0080] Embodiment 1:

[0081] As Figures 1 - 8 shown, it is a preferred Embodiment 1 of a kitchen waste processor of the present utility model. The kitchen waste processor includes a housing 1, a crushing member 2, a driving mechanism 200, a cover body, a magnetic induction switch 301, and a magnetic member 302.

[0082] Among them, as Figures 1 - 3 shown, inside the casing 1 there is a crushing chamber 10. At the top of the crushing chamber 10 there is a feed inlet 10a, and at the lower part of the side wall of the crushing chamber 10 there is a discharge outlet 10b.

[0083] The crushing member 2 is arranged inside the crushing chamber 10 and is used for crushing the garbage entering from the feed inlet 10a. The output end of the driving mechanism 200 acts on the crushing member 2 to drive the crushing member 2 to work. The crushing member and the driving mechanism 200 in this embodiment can be designed with reference to the prior art and will not be elaborated here.

[0084] The above-mentioned cover body is arranged at the feed inlet 10a of the crushing chamber 10 to block the feed inlet 10a, and the feeding cover 3 is arranged to be able to disengage from the feed inlet 10a to open the feed inlet 10a. Specifically, in this embodiment, the cover body is the feeding cover 3. The feeding cover 3 includes an outer cover 31 and an inner cover 32. The outer cover 31 is arranged at the feed inlet 10a of the crushing chamber 10 and is arranged to be able to move upward to disengage from the feed inlet 10a. A through hole 310 penetrating up and down is provided in the center of the outer cover 31. The inner cover 32 is a plate-like body, which is horizontally arranged at the through hole 310 in the center of the outer cover 31 to cover the through hole 310, and the inner cover 32 is arranged to be able to move upward relative to the outer cover 31 to expose the through hole 310. In order to enable the inner cover 32 to be arranged up and down movably in the center of the outer cover 31, support bars 311 are provided at intervals in the circumferential direction and extending radially in the through hole 310 in the center of the outer cover 31. The outer ends of the support bars 311 are connected to the edge of the through hole 310, the inner ends of the support bars 311 are joined, and a vertical connecting cylinder 33 is provided at the joining place. The inside of the connecting cylinder 33 is hollow, and the inner side wall is provided with a first circumferential horizontal extension first plane 331 along the clockwise or counterclockwise direction, an inclined plane 332 extending upward along the first circumferential direction from the edge of the first plane 331, and a second plane 333 extending horizontally along the first circumferential direction from the upper edge of the inclined plane 332. A connecting column 321 extending downward is provided at the center of the lower surface of the inner cover 32, and a convex block 322 is provided on the side surface of the connecting column 321. When the inner cover 32 closes the through hole 310, the convex block 322 is supported on the first plane 331. As the inner cover 32 rotates circumferentially, the convex block 322 moves along the inclined plane 332 to the second plane 333. At this time, the inner cover 32 exposes the through hole 310. For details, please refer to Figure 7 、 8 .

[0085] As Figure 3 、 6As shown in the figure, the above-mentioned magnetic member 302 is a ring-shaped permanent magnet, which is arranged circumferentially around the outer cover 31 and the periphery of the through hole 310. The above-mentioned magnetic induction switch 301 is a reed switch, which is arranged on one side of the machine shell 1 outside the feeding port 10a and is electrically connected to the driving mechanism 200. When the feeding cover 3 is located at the feeding port 10a, the magnetic member 302 is located above the magnetic induction switch 301 and triggers the magnetic induction switch 301, so that the driving mechanism 200 can drive the crushing member 2 to work. When the feeding cover 3 is separated from the feeding port 10a, the magnetic member 302 is outside the induction area of the magnetic induction switch 301.

[0086] Embodiment 2:

[0087] As Figures 9 - 12 shown, this is the second preferred embodiment of a kitchen waste processor of the present utility model. This embodiment is basically the same as Embodiment 1, except that in this embodiment, the magnetic member 302 is a permanent magnet, and there are six magnetic members 302, which are arranged at equal intervals circumferentially around the outer cover 31 and the periphery of the through hole 310. The above-mentioned magnetic induction switch 301 is a reed switch, and there are two magnetic induction switches 301, which are arranged at intervals circumferentially on one side of the periphery of each magnetic member 302 on the machine shell 1. The included angle between the connection line of one magnetic induction switch 301 and the corresponding circumferential center and the connection line of the other magnetic induction switch 301 and the corresponding circumferential center is 45°. So that when the feeding cover 3 is located at the feeding port 10a, at least one of the magnetic induction switches 301 can be triggered by the magnetic member 302. At the same time, in this embodiment, each magnetic induction switch 301 is arranged on the outside of the machine shell 1 through the same box body 300, and the box body 300 is an arc extending circumferentially. The box body 300 is formed by butt-jointing an arc-shaped base and an upper cover from bottom to top. A cavity for restricting each magnetic induction switch 301 therein is provided in the box body 300. C-shaped sockets 303 that can cooperate with the screws on the kitchen waste processor (such as the screws used to install the kitchen waste processor under the sink drain) are provided at both ends of the box body 300 in the extending direction, for the corresponding screws to be inserted horizontally. And a torsion spring 304 that can restrict the screw in the socket is provided at the C-shaped socket 303. One end of the torsion spring 304 is located in the C-shaped socket 303, so that the screw always has a tendency to move into the C-shaped socket 303.

[0088] At the same time, as Figure 9 、 10 shown, the inner cover 32 in this embodiment is a filter plate with filter holes.

[0089] Embodiment 3:

[0090] As Figures 13 - 17As shown, it is a preferred embodiment 3 of a kitchen waste disposer of the utility model. This embodiment is basically the same as the embodiment 1, except that in this embodiment, the cover body is a splash cover 4, and the splash cover 4 includes a support frame 41 and a rubber funnel 42. The support frame 41 is annular and is placed horizontally at the feed port 10a of the crushing chamber 10, and is arranged to be able to move upward and detach from the feed port 10a. A handle 411 is convexly provided on the upper end surface of the support frame 41 to facilitate the placement of the support frame 41. The interior of the support frame 41 has a circumferentially extending annular cavity 410 for the annular magnetic member 302 to be arranged therein. And the outer ring wall of the support frame 41 is provided with a circumferentially extending annular groove 412, and a sealing ring 413 is provided in the annular groove 412; when the splash cover 4 is located at the feed port 10a, the side circumferential surface of the sealing ring 413 is in contact with the inner wall of the feed port 10a. The rubber funnel 42 is an existing structure, which is conical, arranged on the inner periphery of the support frame 41, and is provided with a small hole 401 and a slit 402 (the small hole 401 is located in the center of the rubber funnel, and there are multiple slits 402 arranged at intervals along the circumferential direction) to connect the crushing chamber 10 with the outside so that the garbage from the outside can enter the crushing chamber 10 through the splash cover 4. And because the rubber funnel 42 itself is elastic, the small hole 401 and the slit 402 on the rubber funnel 42 can be elastically deformed and relatively opened under the action of the garbage falling in.

[0091] In this embodiment, the splash-proof cover 4 with a magnetic part 302 cooperates with the magnetic induction switch 301 on the casing so that only when the splash-proof cover 4 is located at the feed port 10a, the driving mechanism 200 can drive the crushing part 2 to work and crush the kitchen waste, thereby ensuring safety. At this time, the kitchen waste from the outside can enter the crushing chamber through the small holes 401 and / or the slits 402 on the splash-proof cover 4 to achieve safe and continuous feeding; and when the splash-proof cover 4 is separated from the feed port 10a, the driving mechanism 200 stops working, and at this time, the kitchen waste from the outside can directly enter the crushing chamber 10 through the feed port 10a, thereby achieving intermittent feeding.

[0092] Embodiment 4:

[0093] like Figures 18 - 22As shown, this is the fourth preferred embodiment of a kitchen waste processor of the present utility model. This embodiment is basically the same as Embodiment Four, except that the structure of the rubber funnel 42 in this embodiment is different. Specifically, in this embodiment, the rubber funnel 42 has a bottom wall 420, a first side wall 421, a second side wall 422, a third side wall 423, and a top wall 424. There is a small hole 401 in the center of the bottom wall 420. The first side wall 421 extends vertically upward from the edge of the bottom wall 420, and there are five first side walls 421, which are arranged at equal intervals in the circumferential direction. The second side wall 422 extends upward and outward from the edge of the bottom wall 420, and there are five second side walls 422, which are respectively located between two adjacent first side walls 421. There are also five top walls 424. Each top wall 424 extends radially outward from the upper edge of the corresponding first side wall 421 along the radial direction of the support frame 41, and each top wall 424 has two radially extending radial edges. The outer edges of each top wall 424 are connected in sequence in the circumferential direction and are constrained by the support frame 41, so that the rubber funnel 42 is constrained within the inner circumference of the support frame 41. There are ten third side walls 423. Each third side wall 423 extends vertically downward from the corresponding radial edge, and the lower edge of the third side wall 423 is joined to the inclined edge of the corresponding second side wall 422. The vertical edge inside the third side wall 423 is joined to the vertical edge of the corresponding first side wall 421. Thus, each top wall 424, the third side walls 423 on both sides of the top wall 424, and the corresponding first side wall 421 form a convex part, and each second side wall 422 and the third side walls 423 on both sides of the second side wall 422 form a concave part.

[0094] Meanwhile, in this embodiment, each first side wall 421 has a first strip-shaped groove 425 extending vertically in the center as the first weak part, and the peripheral part of the bottom wall 420 has a second strip-shaped groove 426 extending radially at the position corresponding to each first strip-shaped groove 425 as the second weak part. For details, please refer to Figure 18 、 19 、20. Under the action of external force, the first weak part and the second weak part can be longitudinally cut open to form a slit 402. For details, please refer to Figure 21 、 22 . There are five slits 402, which are arranged radially around the outer circumference of the small hole 401, and the inner ends of each slit 402 open at the edge of the small hole 401.

However, these terms are used herein only for the purpose of convenience of description and are determined based on the exemplary orientations shown in the drawings. Since the disclosed embodiments of the present utility model can be arranged in different directions, these terms indicating directions are only for illustration and should not be regarded as limitations. For example, "upper" and "lower" are not necessarily limited to the directions opposite to or consistent with the direction of gravity.

[0096] In the description and claims of the present utility model, the term "vertical" is also used, which means basically along the up and down direction, not limited to just the vertical direction, and can also be slightly skewed relative to the vertical direction.

[0097] In the description and claims of the present utility model, the term "radial" is also used, which means basically along the inside and outside direction, not limited to just the radial direction passing through the center of the circle, and can also be slightly skewed relative to the radial direction.
