Description

TECHNICAL FIELD

[0001] The utility model belongs to garbage disposal technical field, concretely relates to a feeding cover for kitchen garbage disposer and kitchen garbage disposer. BACKGROUND

[0002] The existing kitchen garbage disposer generally includes a casing with an inlet and an outlet, a crushing element arranged in the casing, and a driving mechanism for driving the crushing element to work. The crushing element can crush the kitchen garbage entering from the inlet under the driving of the driving mechanism.

[0003] Specifically, the Chinese utility model patent "Kitchen garbage disposer" with the patent number 202221965311.8 and the authorized 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 at the top. The lower grinding cover has a discharge port on the top. An annular wall is installed on the inner circumferential wall of the lower side of the upper grinding cover. The annular wall is above the grinding disc. An annular cavity is formed between the annular wall and the upper grinding cover. A water inlet is opened on the outer circumferential wall of the upper grinding cover and is connected to the annular cavity. Water outlets are opened on the inner wall of the annular cavity. An annular cutter that can rotate under the action of water pressure is installed in the annular cavity.

[0004] For example, the Chinese utility model patent "Kitchen garbage disposal system" with the patent number 202321652436.X and the authorized announcement number CN220538788U includes a sink and a garbage disposer arranged below the sink. The garbage disposer includes a grinding cavity and a grinding disc arranged in the grinding cavity. The grinding cavity has a discharge port below the grinding disc. The top of the step structure of the sink is provided with a main feeding port. A feeding cover is installed on the main feeding port. The top of the grinding cavity is installed on the main feeding port.

[0005] The design of the existing kitchen garbage disposer not only considers the crushing effect but also considers the user's experience and safety. In order to facilitate feeding and avoid garbage splashing from the inlet during disposal, a feeding cover is generally arranged at the inlet. The feeding cover may accumulate dirt and stick after long-term use. Therefore, the feeding cover needs to be cleaned regularly. However, the existing feeding cover has a structure with wrinkles, which is inconvenient to clean.

[0006] Meanwhile, in order to facilitate the entry of external kitchen waste into the crushing chamber through the feed inlet, kitchen waste disposers are generally equipped with a feeding rod that can push the waste, such as the structures disclosed in Chinese utility model patent application number 201921556409.6 "A feeding rod for a garbage disposer" (authorization announcement number CN 211816668U) and Chinese invention patent application number 202410151006.2 "A garbage disposer and processing method" (application publication number CN118223574A). Utility Model Content

[0007] The first technical problem to be solved by this utility model is to provide a feeding cover for a food waste disposer, which is convenient for feeding and cleaning at the same time, in view of the current situation of the prior art.

[0008] The second technical problem to be solved by this utility model is to provide a kitchen waste disposer with the above-mentioned feeding cover.

[0009] The technical solution adopted by this utility model to solve the first technical problem mentioned above is: a feeding cover for a kitchen waste disposer, comprising:

[0010] The bracket has vertically extending side walls and is used for installation into the feed inlet of the food waste disposer;

[0011] A cover is disposed on the inner periphery of the side wall of the bracket;

[0012] Its features are:

[0013] The cover has a vertically extending annular wall, a top wall extending backward and outward from the upper edge of the annular wall, and a bottom wall extending backward and outward from the lower edge of the annular wall. The outer periphery of the top wall is joined to the upper part of the side periphery of the support, and the outer periphery of the bottom wall is joined to the lower part of the side periphery of the support. The annular wall, top wall, and bottom wall are arranged to undergo elastic deformation under external force, causing the annular wall to expand outward and increasing the flow area on the cross-section of the first channel enclosed by the annular wall itself, so as to allow kitchen waste to pass through.

[0014] In this way, the increased flow area of ​​the first through-hole allows kitchen waste to pass through, facilitating feeding. Furthermore, when the external force disappears, the ring wall retracts inward under its own elasticity and returns to its original position. The top and bottom walls connected to the ring wall then act as a "lid," shielding the inner perimeter of the support. Simultaneously, the top and bottom walls also assist in the deformation of the ring wall. Moreover, compared to existing pleated feeding covers, the surfaces of the top, bottom, and ring walls in this invention are smoother, facilitating cleaning of the feeding cover.

[0015] In this invention, under natural conditions without external force, the flow area of ​​the first channel enclosed by the ring wall itself is small or close to zero, and is smaller than the flow area of ​​the first channel enclosed by the ring wall after deformation under external force.

[0016] Preferably, an annular space is defined between the ring wall, top wall, bottom wall, and the corresponding side walls of the support, and the bottom wall is provided with vent holes penetrating its own wall thickness. The existence of the annular space facilitates the elastic deformation of the ring wall, top wall, and bottom wall, and when the ring wall expands outward, the air in the annular space is compressed and discharged through the vent holes; furthermore, when there is water in the annular space, the water can also be discharged through the vent holes along with the air under the action of compression.

[0017] Preferably, there are at least two vent holes, which are arranged circumferentially at intervals around the periphery of the annular wall.

[0018] Preferably, the inner circumferential surface of the side wall has a constricted section whose diameter gradually decreases from top to bottom, an upper section extending vertically upward from the upper end of the constricted section, and a lower section extending vertically downward from the lower end of the constricted section.

[0019] The upper section is provided with a circumferentially extending upper annular groove, and the outer periphery of the top wall is connected to a circumferentially extending upper fixing frame and constrained within the upper annular groove by the upper fixing frame;

[0020] The lower section is provided with a circumferentially extending lower annular groove, and the outer periphery of the bottom wall is connected to a circumferentially extending lower fixing frame and constrained within the lower annular groove by the lower fixing frame.

[0021] The above structure makes the annular space larger at the top and smaller at the bottom, which is conducive to the discharge of air and water in the annular space through the vents at the bottom of the annular space.

[0022] Preferably, the annular wall, top wall, and bottom wall are connected as a single unit.

[0023] Furthermore, the integral component is made of rubber.

[0024] In the above design, preferably, the connection between the ring wall and the top wall, and the connection between the ring wall and the bottom wall, are both smooth arc-shaped structures. The arc-shaped structure facilitates cleaning and also allows for the passage of kitchen waste.

[0025] In the above embodiments, preferably, a resilient contraction ring is further included, which is circumferentially fitted around the outer periphery of the ring wall, so that the ring wall always tends to contract inward, thereby reducing the flow area of ​​the first channel. The design of the contraction ring facilitates the inward contraction and repositioning of the ring wall.

[0026] The technical solution adopted by this utility model to solve the second technical problem mentioned above is: a kitchen waste disposer, comprising:

[0027] The machine casing has a grinding chamber inside, with a feed inlet at the top and a discharge outlet at the bottom.

[0028] 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;

[0029] The feature is that it also includes a feeding cover as described above, which is located at the feed inlet of the crushing chamber to block the feed inlet. The first channel enclosed by the ring wall is used to allow external kitchen waste to pass through and enter the crushing chamber, and the force applied to the ring wall when the kitchen waste passes through is the external force.

[0030] In this way, when kitchen waste passes through, the ring wall expands outward to allow the kitchen waste to pass through; after the feeding is completed, the ring wall retracts inward and returns to its original position under its own elastic force.

[0031] To improve safety, preferably, the feeding cover is arranged so that the feeding port can be opened by detaching it from the feeding port;

[0032] It also includes a magnetic induction switch and a magnetic component, one of which is selectively disposed on the housing and the support of the feeding cover. The magnetic induction switch is electrically connected to the drive mechanism. When the feeding cover is detached from the feed inlet, the magnetic component is located outside the sensing area of ​​the magnetic induction switch. When the feeding cover is located at the feed inlet, the magnetic component triggers the magnetic induction switch, thereby enabling the drive mechanism to drive the crushing component to work.

[0033] Therefore, the drive mechanism can only drive the crushing parts to crush kitchen waste when the feeding cover is placed at the inlet, thus ensuring safe use.

[0034] Compared with existing technologies, the advantages of this invention are as follows: the increased flow area of ​​the first through hole allows kitchen waste to pass through, facilitating feeding; and when the external force disappears, the ring wall retracts inward and returns to its original position under its own elasticity, while the top and bottom walls connected to the ring wall act as a "lid," covering the inner perimeter of the support; simultaneously, the top and bottom walls connected to the ring wall also assist in the deformation of the ring wall. Furthermore, compared with existing pleated feeding covers, the structural surfaces of the top, bottom, and ring walls in this invention are smoother, facilitating cleaning of the feeding cover.

[0040] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0041] like Figures 1-5 As shown, this utility model provides a feeding cover for a food waste disposer and a preferred embodiment of the food waste disposer. The feeding cover includes a support 1, a cover body 2, and a shrink ring 3.

[0042] The bracket 1 has a vertically extending side wall 10. The inner circumferential surface of the side wall 10 has a contraction section 11 with a gradually decreasing diameter from top to bottom, an upper section 12 extending vertically upward from the upper end of the contraction section 11, and a lower section 13 extending vertically downward from the lower end of the contraction section 11. The upper section 12 is provided with a circumferentially extending upper annular groove 121, and the lower section 13 is provided with a circumferentially extending lower annular groove 131.

[0043] The cover 2 is located within the inner perimeter of the side wall 10 of the support 1, and has a vertically extending annular wall 20, a top wall 21 extending outward from the upper edge of the annular wall 20, and a bottom wall 22 extending outward from the lower edge of the annular wall 20. The connection between the annular wall 20 and the top wall 21, and the connection between the annular wall 20 and the bottom wall 22, are both smooth arc-shaped structures. The outer perimeter of the top wall 21 is connected to a circumferentially extending upper fixing frame 122, and is constrained within the upper annular groove 121 by the upper fixing frame 122, thus engaging with the upper part of the side wall 10. The outer perimeter of the bottom wall 22 is connected to a circumferentially extending lower fixing frame 132, and is constrained within the lower annular groove 131 by the lower fixing frame 132, thus engaging with the lower part of the side wall 10. Furthermore, the annular wall 20, top wall 21, and bottom wall 22 are connected as a single piece of rubber material. The annular wall 20, top wall 21, and bottom wall 22 are arranged to undergo elastic deformation under external force, causing the annular wall 20 to expand outwards and increasing the flow area of ​​the first channel 201 enclosed by the annular wall 20, allowing food waste to pass through. Simultaneously, an annular space 100 is defined between the annular wall 20, top wall 21, bottom wall 22, and the corresponding side peripheral walls 10 of the support 1. The bottom wall 22 is provided with ventilation holes 221 penetrating its own wall thickness. Multiple ventilation holes 221 are arranged circumferentially around the periphery of the annular wall 20.

[0044] The aforementioned contraction ring 3 is elastic and is circumferentially fitted around the outer periphery of the ring wall 20 so that the ring wall 20 always tends to contract inward, thereby reducing the flow area of ​​the first channel 201.

[0045] like Figures 1-3 As shown, the above-mentioned food waste disposer includes a shell 4, a crushing component 5, a drive mechanism 6, a magnetic induction switch 7, a magnetic component 8, and a feeding cover.

[0046] The housing 4 has a crushing chamber 40 inside, the top of the crushing chamber 40 has a feed inlet 40a, and the lower side wall of the crushing chamber 40 has a discharge outlet 40b.

[0047] The pulverizer 5 is disposed in the pulverizing chamber 40 and can work under the drive of the drive mechanism 6 to pulverize the kitchen waste entering from the feed inlet 40a. In this embodiment, the drive mechanism 6 is a motor, and the pulverizer is a grinding disc connected to the motor shaft. The grinding disc rotates under the drive of the motor shaft to pulverize the kitchen waste, and the structure of the grinding disc is the same as that of the prior art, which will not be described in detail here.

[0048] The aforementioned feeding cover is located at the feed inlet 40a of the crushing chamber 40 to block the feed inlet 40a. The first channel 201 enclosed by the annular wall 20 allows external kitchen waste to pass through and enter the crushing chamber 40. The force exerted on the annular wall 20 by the kitchen waste passing through is the external force. Thus, when the kitchen waste enters the annular wall 20 under the compression of the existing feeding rod, the annular wall 20 and the shrinking ring 3 outside the annular wall 20 expand outward, increasing the flow area of ​​the first channel 201 defined by the annular wall 20, allowing the kitchen waste to pass through the first channel smoothly. After the kitchen waste is fed in, the cover 2 and the shrinking ring 3 return to their original position under their own elastic force. At this time, the annular wall contracts inward, reducing the flow area of ​​the first channel 201. Simultaneously, the feeding cover can detach upward from the feed inlet 40a, opening the feed inlet 40a. When it is necessary to open the feed inlet 40a, the structural design of the cover 2 in this embodiment allows the user's fingers (or other tools such as a feeding rod) to be inserted into the first channel 201 and apply force to the bottom wall 22, thereby lifting the feeding cover upwards, which facilitates the disassembly and assembly of the feeding cover.

[0049] The aforementioned magnetic component 8 is a ring magnet, which is circumferentially disposed within the support 1 of the feeding cover. The aforementioned magnetic induction switch 7 is a conventional reed switch, which is located on the housing 4 corresponding to the feed inlet 40a. The magnetic induction switch 7 is electrically connected to the drive mechanism 6. When the feeding cover is detached from the feed inlet 40a, the magnetic component 8 is outside the sensing area of ​​the magnetic induction switch 7, thus driving the drive mechanism 6. When the feeding cover is located at the feed inlet 40a, the magnetic component 8 triggers the magnetic induction switch 7, enabling the drive mechanism 6 to drive the pulverizer 5 to work. Thus, the drive mechanism 6 can only drive the pulverizer 5 to pulverize kitchen waste when the feeding cover is located at the feed inlet 40a, thereby ensuring safe use.

[0050] In the specification and claims of this utility model, terms indicating direction, such as "front," "rear," "upper," "lower," "left," "right," "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.

[0051] 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.
