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] The general structure of existing food waste disposers is similar, including 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 considering the grinding effect, the design of existing food waste disposers must also consider the user experience and safety of use, such as the convenience of users when putting in garbage, whether the garbage will splash out from the feed port during disposal, etc. In order to avoid splashing out from the feed port during disposal, a feeding cover is generally set at the feed port. When feeding, the feeding cover is opened to expose the feed port. After feeding, the feeding cover is covered for garbage disposal. However, sometimes people forget to cover the feeding cover after feeding. At this time, when the machine is running, the hand can reach 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. Utility Model Content

[0006] The first technical problem to be solved by the utility model is to provide a kitchen waste disposer which is convenient for disposing of garbage in view of the current status of the prior art.

[0007] The second technical problem to be solved by the utility model is to provide a kitchen waste disposer to improve the safety of use.

[0008] The technical solution adopted by the utility model to solve the above-mentioned first technical problem is: a kitchen waste disposer, comprising:

[0009] A casing having a crushing chamber inside, a feed port is provided at the top of the crushing chamber, a discharge port is provided at the bottom of the crushing chamber, and the edge of the feed port extends outward to form an upper end surface facing upward;

[0010] A crushing element is arranged in the crushing chamber and is used to crush the garbage entering from the feed inlet;

[0011] A driving mechanism, the output end of which acts on the crushing member to drive the crushing member to work;

[0012] A feeding cover is arranged at the feeding port of the pulverizing chamber;

[0013] The feature of the invention is that the feeding cover comprises:

[0014] A handle is disposed at the center of the feed opening in a manner that allows it to move up and down;

[0015] A sealing ring with elasticity, whose inner periphery is circumferentially arranged on the periphery of the handle and constrained together with the handle, and whose outer periphery extends outwardly relative to the handle to form a free edge, wherein the free edge is located on the periphery of the feed port, and when the handle moves downward to a first position, the free edge is affixed to the upper end surface to close the feed port, and when the handle moves to a second position located above the first position, the free edge is separated from the upper end surface to open the feed port.

[0016] When it is necessary to put in garbage, the user can move the handle to the second position to open the feed port, and the kitchen waste enters the crushing chamber of the casing through the feed port. Since the sealing ring is elastic, it can ensure that the kitchen waste can pass through the feed port smoothly through its own elastic deformation, and prevent the kitchen waste from being stuck at the feed port. After the feeding is completed, the user can move the handle to the first position to close the feed port. At this time, the free edge of the outer periphery of the sealing ring fits on the upper end surface of the outer periphery of the feed port, which has a good sealing effect, prevents the kitchen waste from splashing out of the feed port when the machine is running, and can prevent the odor in the machine from overflowing. At the same time, whether the handle is in the first position or the second position, the structural design of the sealing ring in the utility model has the function of preventing the kitchen waste from splashing upward.

[0017] Preferably, when the handle is in the second position, the sealing ring is gradually tilted downward from the inside to the outside. The tilted sealing ring is conducive to the kitchen waste sliding down along the upper surface of the sealing ring and entering the feed inlet; and when the handle moves from the second position to the first position, the free edge of the outer periphery of the sealing ring first contacts the upper end surface of the outer periphery of the feed inlet to ensure the sealing effect.

[0018] Preferably, the wall thickness of the sealing ring gradually decreases from the inside to the outside. That is, the thickness of the free edge of the outer periphery of the sealing ring is thinner, which is conducive to the free edge and the upper end surface of the outer periphery of the feed port to fit together; the thickness of the inner periphery of the sealing ring is thicker, which is conducive to the sealing ring and the handle being constrained together.

[0019] To further improve the sealing effect, preferably, when the handle is in the first position, the sealing ring undergoes elastic deformation so that the free edge of the sealing ring and the portion adjacent to the free edge fit the upper end surface as a whole. The inclined setting and thickness design of the sealing ring in the utility model are conducive to the elastic deformation of the sealing ring.

[0020] Preferably, the feed opening is provided with baffles extending from the edge to the center at intervals along the circumference, the outer ends of the baffles are connected to the edge of the feed opening, and the inner ends of the baffles intersect and are connected to each other for the handle to be arranged thereon. The design of the baffles does not affect the passage of kitchen waste.

[0021] In the above schemes, preferably, the top of the crushing chamber is open and is provided with a cover that can cover the opening, and the cover is arranged to be able to detach upward from the opening to open the opening. At the same time, the center of the cover is provided with the above-mentioned feed port that passes through from top to bottom.

[0022] In this way, when a large amount or a large volume of kitchen waste needs to be put in, the user can lift the handle to open the lid upwards to expose the opening, and the kitchen waste directly enters the crushing chamber of the casing through the opening; on the contrary, when the kitchen waste is less or the volume is smaller, the lid can be closed and the handle can be moved to the second position to open the feed port, and the kitchen waste enters the crushing chamber of the casing through the feed port, thereby facilitating the feeding.

[0023] To further solve the second technical problem mentioned above, preferably, it also includes a magnetic induction switch and a magnetic part, which are selectively arranged on the casing and the cover respectively, and the magnetic induction switch is electrically connected to the driving mechanism. When the cover is separated from the opening, the magnetic part is located outside the sensing area of ​​the magnetic induction switch; when the cover is located at the opening, the magnetic part triggers the magnetic induction switch so that the driving mechanism can drive the crushing part to work.

[0024] The design of the magnetic member and the magnetic induction switch electrically connected to the driving mechanism in the utility model ensures that the driving mechanism can drive the crushing member to work and crush the kitchen waste only when the cover is set at the open position, thereby ensuring safe use.

[0025] Preferably, the magnetic member is arranged on the cover, and the magnetic induction switch is arranged on the casing.

[0026] Preferably, there are at least two magnetic members, and when the cover is located at the opening, the magnetic members are arranged at intervals in the circumferential direction of the opening, 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 induction switch can be triggered when the cover is placed at any position of the opening.

[0027] Furthermore, there are at least two magnetic induction switches, which are arranged at intervals along the circumferential direction. When the cover is located at the opening, at least one of the magnetic induction switches can be triggered by the magnetic member.

[0028] Furthermore, there are six magnetic parts arranged at equal intervals along the circumferential direction, there are two magnetic induction switches, and the angle between the line connecting one of the magnetic induction switches and the corresponding circumferential center and the angle between the line connecting the other magnetic induction switch and the corresponding circumferential center is 45°.

[0029] In the above scheme, preferably, each magnetic induction switch is arranged on the outside of the housing through the same box body, and the box body is in an arc shape extending circumferentially, and a cavity is provided in the box body for each magnetic induction switch to be constrained therein.

[0030] In order to constrain the box body and the casing together, preferably, both ends of the box body in the extension direction are provided with C-shaped sockets that can cooperate with the screws on the food waste disposer, so that the corresponding screws can be inserted horizontally.

[0031] In order to improve the structural stability and prevent the box body from accidentally detaching from the casing, preferably, a torsion spring that can constrain the screw in the socket is provided at the C-shaped socket, and 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.

[0032] Furthermore, the box body is formed by an arc-shaped base and an upper cover which are butt-jointed one above the other.

[0033] Preferably, the magnetic induction switch is a reed switch; and the magnetic member is a permanent magnet.

[0034] Compared with the prior art, the advantages of the present invention are: when it is necessary to put in garbage, the user can move the handle to the second position to open the feed port, and the kitchen waste enters the crushing chamber of the casing through the feed port, and because the sealing ring is elastic, it can ensure that the kitchen waste can smoothly pass through the feed port through its own elastic deformation, and avoid the kitchen waste from being stuck at the feed port; after the feeding is completed, the user can move the handle to the first position to close the feed port, and at this time, the free edge of the outer periphery of the sealing ring fits on the upper end surface of the outer periphery of the feed port, which has a good sealing effect, avoids the kitchen waste from splashing out of the feed port when the machine is running, and can avoid the odor in the machine from overflowing. At the same time, whether the handle is in the first position or the second position, the structural design of the sealing ring in the present invention has the function of preventing the kitchen waste from splashing upward.

[0043] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0044] like Figures 1 to 8 As shown, a preferred embodiment of a food waste disposer of the present invention is shown, which includes a housing 1, a crushing part 2, a driving mechanism 200, a cover 34, a feeding cover 3, a magnetic induction switch 301 and a magnetic part 302.

[0045] Among them, Figures 1 to 3 As shown, the housing 1 has a grinding chamber 10 therein, the top of the grinding chamber 10 has an opening 100 , and the lower part of the side wall of the grinding chamber 10 has a discharge port 10 b .

[0046] The crushing element 2 is arranged in the crushing chamber 10, and is used to crush the garbage entering from the opening 100. The output end of the driving mechanism 200 acts on the crushing element 2, and is used to drive the crushing element 2 to work. The crushing element 2 and the driving mechanism 200 in this embodiment can be designed with reference to the prior art, and will not be described in detail here.

[0047] The lid 34 is arranged at the opening 100 of the pulverizing chamber 10 to cover the opening 100, and the lid 34 is arranged to move upward and detach from the opening 100 to open the opening 100. A feed port 10a is provided in the center of the lid 34, and the edge of the feed port 10a extends outward to form an upper end surface 101 facing upward. Bars 33 extending from the edge to the center are provided at intervals along the circumferential direction in the feed port 10a, and the outer ends of the bars 33 are connected to the edge of the feed port 10a, and the inner ends of the bars 33 intersect and are connected, so that the feeding cover 3 can be provided thereon.

[0048] The above-mentioned feeding cover 3 includes a handle 31 and a sealing ring 32. The handle 31 is arranged on the inner end of each baffle 33 in a manner that it can move up and down (the connection structure between the handle 31 and the inner end of the baffle 33 is: a vertical mounting column is provided at the connection of the inner end of the baffle, and the handle is provided on the outer periphery of the mounting column or the handle is inserted into the channel inside the mounting column, so that the handle can move up and down along the mounting column, and at the same time, a limiting structure that can fix the handle at a desired position is provided between the handle and the mounting column, such as a matching ball and groove are provided between the handle and the side wall of the mounting column). The sealing ring 32 is elastic, and its inner periphery is arranged at the periphery of the handle 31 along the circumferential direction and is constrained together with the handle 31. Its outer periphery extends outward relative to the handle 31 to form a free edge 321, and the free edge 321 is located at the periphery of the feed port 10a. The wall thickness of the sealing ring 32 gradually decreases from the inside to the outside. When the handle 31 moves downward to the first position, the sealing ring 32 undergoes elastic deformation so that the free edge 321 of the sealing ring 32 and the part adjacent to the free edge 321 are integrally attached to the upper end surface 101. When the handle 31 moves to the second position located above the first position, the free edge 321 is separated from the upper end surface and the feed port 10a is opened. At this time, the sealing ring 32 gradually tilts downward from the inside to the outside and is in the shape of an umbrella as a whole. The umbrella-shaped sealing ring 32 can effectively prevent the kitchen waste in the crushing chamber from splashing upward, and is conducive to the kitchen waste to be fed to move downward along the upper surface of the sealing ring 32 to the feed port 10.

[0049] like Figures 3 to 8As shown, the magnetic member 302 is a permanent magnet, and there are six magnetic members 302, which are arranged on the cover 34 and the periphery of the feed port 10 at equal intervals along the circumferential direction. The above-mentioned magnetic induction switch 301 is a reed switch electrically connected to the drive mechanism 200, and there are two magnetic induction switches 301, which are arranged on one side of the periphery of each magnetic member 302 on the housing 1 at intervals along the circumferential direction. The angle between the line connecting one of the magnetic induction switches 301 and the corresponding circumferential center and the line connecting the other magnetic induction switch 301 and the corresponding circumferential center is 45°. Therefore, when the cover 34 is located at the opening 100, at least one of the magnetic induction switches 301 can be triggered by the magnetic member 302 so that the drive mechanism 200 can drive the crushing member 2 to work; when the cover 34 is separated from the opening 100, the magnetic member 302 is located outside the induction area of ​​the magnetic induction switch 301. At the same time, in this embodiment, each magnetic induction switch 301 is arranged on the outside of the housing 1 through the same box body 300, and the box body 300 is an arc extending in the circumferential direction. The box body 300 is formed by a base and an upper cover connected one below and one above each other. A cavity is provided in the box body 300 for each magnetic induction switch 301 to be restrained therein. Both ends of the box body 300 in the extension direction are provided with a C-shaped socket 303 that can cooperate with the screws on the kitchen waste disposer (such as the screws used to install the kitchen waste disposer under the sink drain) for the corresponding screws to be inserted horizontally. A torsion spring 304 that can restrain the screw in the socket is provided at the C-shaped socket 303, and 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.
