[0001] The utility model belongs to garbage disposal technical field, concretely relates to a kitchen garbage disposal. BACKGROUND

[0002] The existing kitchen garbage disposal generally includes a casing with a feed inlet and a discharge 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 feed inlet under the driving of the driving mechanism.

[0003] Specifically, the Chinese utility model patent "Kitchen garbage disposal" with the patent number 202221965311.8 and the 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 at the top.

[0005] The design of the existing kitchen garbage disposal not only considers the crushing effect but also considers the user experience and safety. In order to avoid garbage splashing from the feed inlet, a feeding cover or a splash cover is generally arranged at the feed inlet. The cover has a channel for the kitchen garbage from the outside to enter the casing. However, the design of the cover may affect the feeding convenience to some extent, and there is a risk of some garbage splashing from the channel. At the same time, the cover may accumulate dirt and stick after long-term use, so it needs to be cleaned regularly. UTILITY MODEL CONTENTS

[0006] The first technical problem to be solved by the utility model is to provide a kitchen garbage disposal that can further avoid garbage splashing.

[0007] The second technical problem to be solved by the utility model is to provide a kitchen garbage disposer facilitating feeding.

[0008] The utility model solves the above-mentioned first technical problem by adopting the technical scheme of a kitchen garbage disposer comprising:

[0009] A shell has a crushing cavity inside, the upper part of the crushing cavity has an upward feeding port, and the lower part of the crushing cavity has a discharging port;

[0010] A crushing part is arranged in the crushing cavity and can work under the drive of a drive mechanism to crush kitchen garbage entering from the feeding port;

[0011] A cover;

[0012] The cover is characterized by being connected with:

[0013] A feeding part is arranged at the feeding port of the crushing cavity to close the feeding port, and the feeding part has a feeding channel for kitchen garbage from outside to pass downward;

[0014] A flow guide part is located below the feeding part, the downwardly extending side wall of the flow guide part is located inside the side wall of the crushing cavity and forms an annular cavity with the side wall, the side wall of the flow guide part defines a flow guide channel, the upper end of the flow guide channel is opposite and connected with the lower end of the feeding channel, and the lower end edge of the flow guide channel is attached to the corresponding side wall of the crushing cavity to make the annular cavity a closed space;

[0015] Meanwhile, the side wall of the flow guide part is provided with water outlets along the circumference;

[0016] The side wall of the crushing cavity is provided with a water inlet hole for the water source from outside to enter at the position corresponding to the annular cavity.

[0017] In this way, when feeding, kitchen garbage from outside can enter the crushing cavity through the feeding channel of the feeding part and the flow guide channel of the flow guide part in sequence; when crushing, the water source from outside can enter the annular cavity through the water inlet hole and then be discharged from the water outlets of the side wall of the flow guide part, and since the water outlets are arranged along the circumference of the side wall of the flow guide part, the water flow output from the water outlets can press down the kitchen garbage to avoid the kitchen garbage from splashing upward. The annular cavity of the utility model can function as a water storage cavity, which is conducive to improving the flow rate of the water flow output from the water outlets and thus conducive to forming a water seal to reduce the noise during the operation of the machine.

[0018] To further solve the above-mentioned second technical problem, preferably, the flow area on the cross section of the feeding channel gradually decreases from top to bottom; and the flow area on the cross section of the flow guide channel gradually increases from top to bottom. In this way, the feeding of kitchen garbage can be facilitated while effectively avoiding the kitchen garbage from splashing upward.

[0019] Further, at least the lower part of the feeding part and at least the upper part of the flow guide part are flexible members capable of being elastically deformed under external force. Thus, the flow area can be expanded under the action of the passing kitchen garbage, which is beneficial to the passing of the kitchen garbage. After the kitchen garbage passes, the flexible members are reset under the action of their own elastic force.

[0020] Preferably, the upper port of the flow guide channel is connected with the lower port of the feeding channel through a flexible hose capable of being elastically stretched and contracted.

[0021] Preferably, the inner wall surface of the feeding channel is a smooth taper surface. This is beneficial to the smoothness of feeding. Of course, in addition to this, the feeding part can also adopt the existing splash-proof cover structure, such as the rubber funnel structure in the utility model patent “Rubber Funnel and Garbage Disposer” with the application number 201920089877.0 and the authorization announcement number CN209854850U.

[0022] In the above-mentioned schemes, preferably, the water outlet holes are at least two and are arranged on the side peripheral wall of the flow guide part in a circumferential direction.

[0023] Preferably, the circumferentially arranged water outlet holes are a group, and there are at least two groups, which are an upper group and a lower group located below the upper group. The water outlet holes of the upper group are inclined upward, and the water outlet holes of the lower group are inclined downward. In this way, the water flow output from the water outlet holes of the upper group can form a water seal, which can reduce noise, clean the surface of the channel, and prevent kitchen garbage from splashing out upward. The water flow output from the water outlet holes of the lower group can flush the kitchen garbage downward.

[0024] Preferably, the water outlet holes of the upper group are in the shape of a strip extending in a circumferential direction, and the water outlet holes of the lower group are in the shape of a circle.

[0025] In the above-mentioned schemes, preferably, the cover is arranged to be movable upward to separate from the feeding port of the crushing cavity; a first magnetic member is arranged on the edge of the lower port of the flow guide channel in a circumferential direction, and correspondingly, a second magnetic member capable of being magnetically attracted to the first magnetic member is arranged on the side wall of the crushing cavity. The cooperation of the first and second magnetic members can ensure that the edge of the lower port of the flow guide channel is attached to the corresponding side wall of the crushing cavity, and when the cover is taken out upward, the first and second magnetic members are automatically separated.

[0026] In order to improve the safety in use, preferably, a magnetic induction switch is further included, which is arranged on the side wall of the crushing cavity and is electrically connected with the driving mechanism. When the cover is located at the feeding port, the magnetic induction switch is triggered so that the driving mechanism can drive the crushing member to work. When the cover separates from the feeding port, the magnetic induction switch is in an untriggered state. Thus, only when the cover is installed in place at the feeding port, the crushing member can work; after the cover is taken out upward, the crushing member stops working.

[0027] Compared with existing technologies, the advantages of this invention are as follows: During feeding, external kitchen waste can sequentially enter the crushing chamber through the feeding channel of the feeding part and the guiding channel of the guiding part; during crushing, external water can enter the annular cavity through the water inlet and then be discharged from the water outlet on the side wall of the guiding part. Because the water outlet is arranged circumferentially along the side wall of the guiding part, the water flow output from the water outlet can press down on the kitchen waste, preventing it from splashing upwards. Furthermore, the annular cavity of this invention can act as a water storage chamber, which helps to increase the flow rate of the water output from the water outlet, thereby facilitating the formation of a water seal and reducing noise during machine operation.

[0033] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0034] like Figs. 1-5 As shown, this is a preferred embodiment of a food waste disposer of the present invention. The food waste disposer includes a shell 1, a crushing component 2, a driving mechanism 3, a cover 4, a magnetic induction switch 6, and a first magnetic component 51 and a second magnetic component 52.

[0035] The housing 1 has a crushing chamber 10 inside, the top of the crushing chamber 10 has an upward-facing feed inlet 10a, and the bottom of the crushing chamber 10 has a discharge outlet 10b.

[0036] The crushing component 2 is disposed inside the crushing chamber 10 and can work under the drive of the drive mechanism 3 to crush the kitchen waste entering from the feed inlet 10a. In this embodiment, the drive mechanism 3 is a motor, and the crushing component 2 is an existing grinding disc. The grinding disc rotates around its own vertically extending axis under the drive of the motor output shaft to crush the kitchen waste entering from the feed inlet 10a.

[0037] The cover has a feeding part 4a connected thereto and a flow guiding part 4b below the feeding part 4a. The feeding part 4a is arranged at the feeding opening 10a of the crushing cavity 10 to close the feeding opening 10a. The feeding part 4a is arranged to be movable upward to be separated from the feeding opening 10a of the crushing cavity 10. Meanwhile, the feeding part 4a has a feeding channel 41 therein through which the kitchen garbage from outside passes downward. The inner wall surface of the feeding channel 41 is a smooth taper surface, so that the flow area of the feeding channel 41 gradually decreases from top to bottom. The flow guiding part 4b has a side wall 42 extending downward. The side wall 42 is located in the inner periphery of the side wall of the crushing cavity 10 and forms an annular cavity 11 therebetween. Meanwhile, the side wall 42 itself defines a flow guiding channel 420. The flow area of the flow guiding channel 420 gradually increases from top to bottom. The upper end of the flow guiding channel 420 is opposite to and communicates with the lower end of the feeding channel 41. A circumferentially extending magnet is arranged at the lower end edge of the flow guiding channel 420 as a first magnetic member 51. Correspondingly, a circumferentially extending annular magnet is arranged on the side wall of the crushing cavity 10 as a second magnetic member 52. The second magnetic member 52 is magnetically attracted to the first magnetic member 51 to make the lower end edge of the flow guiding channel 420 abut against the corresponding side wall of the crushing cavity 10, so that the annular cavity 11 is a closed space. Meanwhile, a water inlet hole 12 is arranged on the side wall of the crushing cavity 10 at a position corresponding to the annular cavity 11 to allow water from outside to enter. A plurality of water outlet holes 421 are circumferentially and spacedly arranged on the side wall 42 of the flow guiding part 4b. The circumferentially and spacedly arranged water outlet holes 421 are grouped into two groups, i.e. an upper group close to the upper end of the flow guiding channel 420 and a lower group close to the lower end of the flow guiding channel 420. The water outlet holes of the upper group are circumferentially extending strips inclined upward, and the water outlet holes of the lower group are circular and inclined downward.

[0038] Meanwhile, in the present embodiment, at least the lower part of the feeding part 4a and the flow guiding part 4b are flexible members made of rubber material and elastically deformable under external force, so that the flow area can be expanded under the action of the passing kitchen garbage to facilitate the passing of the kitchen garbage. Meanwhile, the upper end of the flow guiding channel 420 and the lower end of the feeding channel 41 are connected by a flexible hose 43.

[0039] When feeding, the kitchen waste from outside can pass through the feeding passage 41 of the feeding part 4a, the hose 43 and the guide passage 420 of the guide part 4b in sequence and enter the crushing cavity 10, and during the feeding process, the caliber of the flexible part made of rubber and the hose can be expanded under the action of the passing kitchen waste, which is beneficial to the passing of the kitchen waste. After the feeding is completed, the flexible part made of rubber and the hose are reset under the action of the self elasticity. During the crushing, the water source from outside can pass through the water inlet hole 12 and enter the ring cavity 11, and the ring cavity 11 can be filled with water quickly, the water in the ring cavity 11 is discharged from the water outlet holes, and the water flow output by the water outlet holes on the upper side can form a water seal, so that the noise during the crushing can be reduced, the inner channel of the cover can be cleaned, and the upward splashing of the residual during the crushing can be prevented. At the same time, the water flow output by the water outlet holes on the lower side can flush the kitchen waste together with the water flow output by the water outlet holes on the upper side.

[0040] The above-mentioned magnetic induction switch 6 is arranged on the side wall of the crushing cavity 10 and is electrically connected with the driving mechanism 3, when the cover 4 is located at the feeding port 10a, the magnetic induction switch 6 is triggered to enable the driving mechanism 3 to drive the crushing part 2 to work, when the cover 4 is separated from the feeding port 10a, the magnetic induction switch 6 is in a non-triggered state. Therefore, only when the cover 4 is installed in place at the feeding port 10a, the crushing part 2 can work, and when the cover 4 is taken out upward, the crushing part 2 stops working.
