Description

Technical Field

[0001] The utility model relates to the technical field of food waste treatment, in particular to a food waste disposer and kitchen equipment using the same. 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, the Chinese utility model patent with patent number CN202320241851.X (publication number CN219219251U) discloses a household food waste processor and a sink, which includes a shell having a grinding chamber, a top having a feed port connected to the grinding chamber; a grinding assembly arranged in the grinding chamber; the characteristic is that it also includes a lifting plate, which is arranged in the grinding chamber in a manner that can move up and down relative to the shell, the lifting plate is opposite to the feed port and can open or close the feed port, and there is a gap between the lifting plate and the side wall of the shell for waste food to pass through.

[0004] In this patent, an electric push rod is used to drive the lifting plate (i.e., the sealing cover below) to move up and down, and the grinding assembly also needs to be equipped with a set of driving mechanisms. In this way, the garbage disposer needs to be equipped with two sets of driving mechanisms, involving more components and a more complex structure. Utility Model Content

[0005] The first technical problem to be solved by the utility model is to provide a kitchen waste disposer with a sealing cover and a grinding disc sharing a set of driving mechanisms in view of the current status of the prior art.

[0006] The second technical problem to be solved by the present invention is to provide a kitchen device using the above-mentioned kitchen waste disposer in view of the current status of the prior art.

[0007] The technical solution adopted by the utility model to solve the above-mentioned first technical problem is: a kitchen waste disposer, comprising

[0008] A shell, wherein a grinding chamber is provided inside the shell, and a feed inlet and a discharge port connected to the grinding chamber are provided on the shell;

[0009] A grinding assembly, comprising a grinding disc disposed in a grinding chamber, wherein the grinding disc is rotatable about its axis;

[0010] The driving mechanism comprises a driving member and an output shaft with one end drivingly connected to the driving member, wherein the output shaft is drivingly connected to the grinding disc;

[0011] A sealing cover is disposed in the grinding chamber and can move toward or away from the feed inlet, and the sealing cover can open or close the feed inlet;

[0012] The invention is characterized in that the output shaft is also drivingly connected to the sealing cover.

[0013] The output shaft and the sealing cover can be connected through a transmission component. Preferably, the other end of the output shaft faces the direction of the feed port. A threaded portion extending along its axial direction is provided on a partial section of the output shaft. A threaded hole penetrating through the wall thickness of the sealing cover is provided. The output shaft is inserted into the threaded hole and the two are threadedly connected. The grinding disc and the threaded portion are spaced apart along the axial direction of the output shaft. The output shaft and the sealing cover are connected by screw nut transmission, which has a compact structure and involves few components.

[0014] In the above scheme, the output shaft includes a rod body drivingly connected to the driving member and a fixing sleeve mounted on the rod body, and the threaded portion is arranged on the fixing sleeve. Compared with the method of directly designing the threaded portion on the rod body, the housing adjusts the position of the sealing cover by adjusting the position of the fixing sleeve mounted on the rod body, thereby ensuring the reliability of the sealing cover closing the feed port.

[0015] In order to guide the moving track of the sealing cover, a guide groove extending along the axial direction of the output shaft is provided on the wall surface of the grinding chamber, and a guide block placed in the guide groove and capable of sliding along the guide groove is provided on the peripheral wall of the sealing cover. The cooperation between the guide block and the guide groove not only ensures the axial movement of the sealing cover along the output shaft, but also prevents the sealing cover from tilting during the movement.

[0016] In order to ensure the reliability of the sealing cover closing the feed port, a sealing ring is provided on the sealing cover or the shell. When the sealing cover closes the feed port, the sealing ring is squeezed between the sealing cover and the shell, and the sealing ring is arranged around the outer circumference of the feed port.

[0017] In the above scheme, the sealing ring is arranged on the wall surface of the sealing cover facing the feed port, and the shell is provided with a groove surrounding the outer circumference of the feed port. When the sealing cover closes the feed port, the sealing ring is embedded in the groove.

[0018] In order to guide the garbage entering from the feed inlet to the grinding disc, an impeller is provided between the threaded portion of the output shaft and the grinding disc, and the impeller is relatively fixedly mounted on the output shaft. The rotation of the impeller generates negative pressure in the grinding chamber, which can accelerate the transportation of the garbage at the feed inlet to the grinding disc.

[0019] In order to improve the working efficiency of the impeller, the impeller includes a mounting ring sleeved on the output shaft and at least two blades. The blades are arranged at intervals along the circumference of the mounting ring, and each blade extends spirally from its upper side to the lower side along the circumference of the mounting ring.

[0020] In order to position the other end of the output shaft and prevent the output shaft from shaking during rotation, a mounting ring is provided in the housing, and the other end of the output shaft is inserted into the mounting ring. The outer peripheral wall of the mounting ring is connected to the inner wall surface of the housing through a connecting rib. Thus, one end of the output shaft is positioned by the driving member, and the other end is positioned by the mounting ring, reducing the probability of shaking during the rotation of the output shaft.

[0021] The technical solution adopted by the utility model to solve the above-mentioned second technical problem is: a kitchen device, characterized in that it includes a sink and the above-mentioned kitchen waste disposer, and the bottom wall of the sink is provided with a drain outlet that penetrates the wall thickness, and the drain outlet is fluidically connected to the feed port of the sink.

[0022] The sink can be used as an ordinary sink. In the above scheme, a rotatable spray assembly for spraying water is provided in the sink, and the sink is used as a dishwasher.

[0023] The structure is compact, the shell is arranged below the water tank, and the feed port is arranged on the top of the shell.

[0024] Compared with the prior art, the utility model has the following advantages: the driving mechanism of the utility model includes a driving member and an output shaft drivingly connected to the driving member, and the output shaft is drivingly connected to the sealing cover and the grinding disc at the same time. In this way, through a set of driving mechanism, the sealing cover and the grinding disc can be driven to work at the same time, and the structure is simplified. BRIEF DESCRIPTION OF THE DRAWINGS
