Description

Technical Field

[0001] The invention relates to the technical field of food waste treatment, and in particular to kitchen equipment. Background Art

[0002] With the implementation of the domestic garbage classification policy, not only has the sales volume of classified garbage bins increased significantly, but household waste food disposers (also known as "kitchen waste disposers" or "food waste disposers") have also been accepted by more and more families, especially household waste food disposers installed under the kitchen sink drain, which usually include a feed inlet connected to the sink drain, a grinding chamber, a grinding assembly located in the grinding chamber, and a discharge port connected to a drain pipe. This disposer crushes the food waste in the grinding chamber through the grinding assembly and directly discharges it into the sewer, thereby avoiding the breeding of bacteria, mosquitoes and the emission of odors due to the long-term storage of food waste in the kitchen.

[0003] For example, in the Chinese utility model patent disclosed with patent number CN202320241851.X (publication number CN219219251U), a household food waste disposer and a water sink is disclosed. The household food waste disposer includes a shell having a grinding chamber, and a feed port connected to the grinding chamber at the top; a grinding assembly is arranged in the grinding chamber, and the water sink includes a trough body, and the bottom of the trough body has a water outlet, and the shell is arranged at the water outlet at the bottom of the trough body.

[0004] Currently, food waste disposers are usually used in conjunction with a sink as shown in the above-mentioned patent, but other components that require power are sometimes placed in the sink, such as a cleaning basket for washing fruits and vegetables, such as the "A Fruit and Vegetable Washing Machine" disclosed in the Chinese utility model patent with patent number CN202011063502.0 (publication number CN112220374A).

[0005] As we all know, a food waste disposer needs to be equipped with a set of driving mechanisms to drive the grinding component to work, and the components in the sink, such as the vegetable washing basket, also need power to drive. If the two are each equipped with a set of driving mechanisms, it will involve many components and the device will be relatively large. This problem needs to be further resolved. Summary of the invention

[0006] The technical problem to be solved by the present invention is to provide a kitchen device in which a washing basket and a kitchen waste disposer share a set of driving mechanisms in view of the current status of the prior art.

[0007] The technical solution adopted by the present invention to solve the above technical problems is: a kitchen device, comprising

[0008] Food waste disposer, including

[0009] A shell, wherein the shell has a grinding chamber inside, and the shell is provided with a feed port and a discharge port connected to the grinding chamber, wherein the feed port is arranged at the top of the shell;

[0010] A grinding assembly, comprising a grinding disc horizontally arranged in a grinding chamber, wherein the grinding disc can rotate around its axis;

[0011] The driving mechanism includes a driving member disposed below the grinding chamber and an output shaft drivingly connected to the driving member, wherein the output shaft can rotate around its axis, the output shaft passes through the grinding disc and the two are relatively fixed in the circumferential direction, and the upper end of the output shaft passes through the feed port;

[0012] It is characterized by that it also includes

[0013] The cleaning basket is located above the shell, and includes an outer basket and an inner basket rotatably arranged in the outer basket. There is a gap between the inner wall surface of the outer basket and the outer wall surface of the inner basket to form a water collecting chamber. The outer basket is provided with a water supply port connected to the water collecting chamber, and the bottom wall and / or the peripheral wall of the inner basket are provided with a drain port. The bottom wall of the outer basket is provided with a through hole for the upper end of the output shaft to pass through, and the bottom wall of the inner basket is drivingly connected to the upper end of the output shaft.

[0014] In order to facilitate the driving connection between the upper end of the output shaft and the inner basket, a connecting piece is provided at the upper end of the output shaft, and the connecting piece and the bottom wall of the inner basket can be constrained together in the circumferential direction.

[0015] The connecting piece may have a variety of structural forms. Preferably, the connecting piece includes a transversely arranged plate body, a through hole for the output shaft to pass through is provided at the central portion of the plate body, the plate body and the output shaft are relatively fixed, at least two protrusions are provided on the peripheral wall of the plate body along the circumference thereof, and an embedding groove is formed between two adjacent protrusions, and the inner basket is provided with an embedding block that can be embedded in the embedding groove from top to bottom. In this way, as long as the inner basket is placed from top to bottom so that the embedding block is embedded in the embedding groove, the inner basket and the connecting piece can be circumferentially constrained together.

[0016] In order to prevent the inner basket from shaking when rotating, at least two convex ribs are arranged at intervals along the circumference of the upper surface of the plate body, and the upper surface of the convex ribs can abut against the bottom wall of the inner basket. The convex ribs play a role in supporting the inner basket.

[0017] In order to prevent the connecting piece from being located between the inner basket and the outer basket, resulting in an excessively large distance between the inner basket and the outer basket, thereby causing the cleaning basket to be too large, the bottom wall of the inner basket is partially arched upward to form an accommodating area, and the connecting piece is arranged in the accommodating area, so that the structure is compact.

[0018] Preferably, the output shaft includes a rod body and a transmission shaft, the rod body is drivingly connected to the driving member, the grinding disc is mounted on the rod body, the lower end of the transmission shaft is detachably connected to the rod body via a joint, and the upper end of the transmission shaft is connected to the inner basket. In this way, when the cleaning basket is not in use, the joint and the rod body can be separated, thereby separating the cleaning basket from the food waste disposer, and when the cleaning basket needs to be used, the joint and the rod body are connected, so that the power of the driving member can be transmitted to the grinding disc and the inner basket at the same time.

[0019] In order to connect the rod body and the joint detachably, the joint is provided with a slot with an open bottom, the rod body is detachably inserted into the slot, and the two are relatively fixed in the circumferential direction. In this way, when the cleaning basket is not in use, the rod body can be pulled out of the slot, and the cleaning basket and the food waste disposer can be separated. When the cleaning basket needs to be used, the rod body is inserted into the slot, so that the power of the driving member can be transmitted to the grinding disc and the inner basket at the same time.

[0020] Preferably, the joint and the transmission shaft are connected via a transmission. The function of the transmission is to convert the high speed power (1000-5000r / min) of the garbage disposal motor into a required speed to adapt to the speed requirement of the inner basket.

[0021] In the above scheme, the outer basket is provided with a drain outlet connected to the water collecting chamber, and a valve that can open or close the drain outlet can be provided at the drain outlet. The valve can adopt an existing structure, such as a solenoid valve. When cleaning, the valve closes the drain outlet. When cleaning is completed, the valve opens the drain outlet to discharge dirty water.

[0022] The cleaning basket is arranged in the water tank, and a drain port penetrating the wall thickness is arranged on the bottom wall of the water tank, and the drain port is in fluid communication with the feed port of the shell. The garbage in the water tank and the sewage discharged from the cleaning basket can directly enter the kitchen waste disposer and be discharged from the sewer after being processed.

[0023] In order to prevent the output shaft from shaking when it rotates, the kitchen equipment also includes a fixing seat penetrated through the through hole of the outer basket, the output shaft is rotatably mounted on the fixing seat, and the output shaft is fixed relative to the fixing seat in the radial direction, and a sealing ring is arranged between the fixing seat and the through hole to prevent water leakage.

[0024] In order to position the fixing seat vertically, a lower limit structure for limiting the downward movement of the fixing seat is provided between the fixing seat and the outer basket, and an upper limit structure for limiting the upward movement of the fixing seat is provided between the fixing seat and the water tank.

[0025] The structure is simple. A flange is arranged on the outer peripheral wall of the fixing seat and is placed on the upper surface of the bottom wall of the outer basket. The flange is the lower limit structure.

[0026] The structure is simple, the lower part of the fixed seat is inserted into the drain, and there is a water gap between the outer wall surface of the fixed seat and the inner wall surface of the drain, a limit block is provided on the outer peripheral wall of the lower part of the fixed seat, and a stop block that can be pressed against the upper surface of the limit block is provided on the inner wall surface of the drain, and the stop block and the limit block together constitute the upper limit structure.

[0027] In order to prevent the fixed seat from being driven by the output shaft to rotate in the circumferential direction, the limit block extends along the circumference of the fixed seat, and one end of the limit block is provided with a limit portion that can abut against the stop block in the circumferential direction. The limit block and the limit portion are arranged in sequence along the rotation direction of the transmission shaft, so that the fixed seat cannot rotate circumferentially relative to the output shaft.

[0028] In the above solution, preferably, the cleaning basket can be detachably placed in the sink, so that the cleaning basket can be placed in the sink when it is needed, and removed from the sink when it is not needed.

[0029] In order to make the cleaning basket detachable from the water tank, the outer basket is placed in the water tank. The cleaning basket is placed in the water tank, and the two can be used in combination. The cleaning basket is removed from the water tank, and the water tank can be used alone.

[0030] Preferably, the bottom of the outer basket is provided with supporting feet, and the bottom of the supporting feet is wrapped with flexible parts to reduce the vibration problem caused by the rotation of the inner basket.

[0031] Preferably, the water supply port on the outer basket is located at the lower part thereof, and a plurality of blades are arranged on the bottom wall of the inner basket, and the blades are radially distributed with the central part of the inner basket as the center. The blades centrifugally stir the water to facilitate it to enter the inner basket from bottom to top.

[0032] In order to further make the water at the bottom flow upward, an inverted V-shaped guide rib is provided on the peripheral wall of the inner basket. The guide ribs have at least two arranged at intervals along the vertical direction. The guide ribs arranged in a row along the vertical direction form a guide rib group. The guide rib group has at least two groups and is arranged at intervals along the circumference of the inner basket. The guide ribs can lift the water flow along the side wall of the inner basket, and then cooperate with centrifugal stirring to realize the circulation and cleaning of the water flow along the side wall, repeatedly rinsing the fruits and vegetables, and effectively cleaning them.

[0033] Compared with the prior art, the advantages of the present invention are as follows: the output shaft of the driving mechanism of the present invention passes through the grinding disc and the two are relatively fixed in the circumferential direction, and the upper end of the output shaft passes through the feed port and is connected to the inner basket drive. In this way, a set of driving mechanism is set up, which can simultaneously drive the inner basket and the grinding disc to rotate, and there is no need to set up a set of driving mechanisms for both the food waste disposer and the cleaning basket, and the structure is simplified.
