Description

Technical Field

[0001] The utility model relates to the technical field of food waste treatment, in particular to a food waste disposer. Background Art

[0002] Kitchen waste refers to the waste generated in residents' daily life and food processing, catering services, unit catering and other activities, including discarded vegetable leaves, leftovers, fruit peels, tea dregs, etc. Its main sources are family kitchens, restaurants, hotels, canteens, markets and other industries related to food processing. People generally throw vegetable leaves, fruit shells and leftover food on plates into the trash can, but the grease and sauce in the leftover food easily stick to the inner wall of the trash can, making it difficult to clean the trash can, and you also need to carry the trash can out of the room and dump the kitchen waste in the public garbage disposal area. In response to the above problems, a kitchen waste disposer can break up the kitchen waste, and the broken kitchen waste can be flushed into the sewer.

[0003] For example, the Chinese utility model patent with patent number CN202223135590.8 (publication number CN218643471U) discloses a garbage disposer with multi-directional water spray, which includes a shell assembly and an inner tank. The inner tank is provided with a machine base, an outer cover, and a rotatable cutter disc. The cutter disc is provided with a main cutter and an auxiliary cutter, which are respectively located on the outer side and the inner side of the cutter disc. The machine base is provided with a motor that can drive the cutter disc to rotate. The outer cover is provided with a cutting blade, a water baffle, a water inlet hole, a feed hole, and a discharge hole. The water inlet hole is provided with a detachable water inlet joint. A sealed water tank is formed between the outer cover and the water baffle. The water inlet hole penetrates the water tank. The water baffle is provided with a plurality of water spray holes. One end of the water inlet pipe is connected to the water inlet joint, and the other end of the water inlet pipe is provided with a solenoid valve. The solenoid valve is connected to the tap water joint in the room. When the solenoid valve is opened, tap water enters the water tank through the water inlet pipe.

[0004] The water inlet method of this patent has the following problems: 1. The slag discharge speed is slow, because the water from the faucet enters the grinding chamber, the flow rate loss is large, the slag discharge effect is poor, and it is relatively wasteful; 2. The grinding chamber cannot be cleaned, also because the water from the faucet enters the grinding chamber with basically no impact force.

[0005] In addition to the above-mentioned defects of the water inlet method, it can be seen from the figure that the water spray holes on the water-blocking plate are facing the grinding disc, and can only jet the garbage on the grinding disc, while garbage is easily accumulated in the gap between the outer edge of the grinding disc and the inner tank.

[0012] Preferably, at least one of the second water holes has a different height from the other second water holes, so that the second water holes are located at different heights and impact on the upper surface of the grinding disc at different positions, thereby flushing the grinding disc over a large area.

[0013] In order to make the water flow ejected from the water outlet have a greater impact force, the water inlet is connected to a water inlet pipe, and the water inlet pipe is connected to a pressure boosting device for pressurizing the water. In this way, after the water is pressurized by the pressure boosting device, the impact force when it is ejected from the water outlet is greater, the impact force on the garbage is also greater, and the flushing effect on the grinding chamber is good.

In this way, the water flow ejected from the first water holes 15 will impact the garbage between the grinding disc 2 and the grinding chamber 11, and quickly wash away the garbage, thereby preventing the garbage from accumulating between the grinding disc 2 and the grinding chamber 11, affecting the discharge of the garbage, and also causing poor cleanliness in the grinding chamber 11.

[0032] The water outlet also includes a plurality of second water holes 16 spaced apart along the circumference of the grinding chamber 11. The second water holes 16 are located above the first water holes 15. The second water holes 16 are inclined inward from top to bottom (inward refers to the direction close to the center line of the grinding chamber 11). In this way, the water flow ejected from the second water holes 16 will impact the garbage accumulated on the surface of the grinding disc 2 and wash away the garbage. At least one of the second water holes 16 is at a different height from the other second water holes 16. In this way, the second water holes 16 are at different heights and the positions impacting the upper surface of the grinding disc 2 are also different, so as to form a large-area flushing of the grinding disc 2.

[0033] The water inlet 10 is connected to a water inlet pipe 4, which is connected to a pressure boosting device for pressurizing water. In this way, after the water is pressurized by the pressure boosting device, the impact force when it is sprayed out from the water outlet is relatively large, and the impact force on the garbage is also relatively large, and the flushing effect on the grinding chamber 11 is good.

[0034] In this embodiment, the boosting device includes a pump casing having a pump chamber 17 and an impeller 5 arranged in the pump chamber 17. The pump casing has a water inlet 18 and a water outlet 19 connected to the pump chamber 17. The water outlet 19 is connected to the water inlet end of the water inlet pipe 4. The impeller 5 is used to transport water from the water inlet 18 to the water outlet 19. The boosting device adopts the structural form of a boosting pump, and the pressurizing effect is good.

[0035] like Figure 6 As shown, the impeller 5 includes a mounting ring 51, blades 52 and a cover plate 53. The mounting ring 51 is for mounting the first output shaft 32 below. The blades 52 have at least two pieces and are spaced apart along the circumference of the mounting ring 51. The inner ends of the blades 52 are mounted on the outer peripheral wall of the mounting ring 51. The outer ends of the blades 52 extend in a direction away from the center line of the mounting ring 51. The blades 52 are inclined from the inner ends to the outer ends along the circumference of the mounting ring 51. There are two cover plates 53 and they are spaced apart from each other. The outer ends of the blades 52 are arranged between the two cover plates 53.

[0036] The water inlet 18 is located below the mounting ring 51, and the water outlet 19 is arranged on the peripheral side of the blade 52. A water inlet valve 6 is arranged at the water inlet 18 to control whether water flows into the pump chamber 17. The water inlet valve 6 can adopt an existing structure, such as a solenoid valve.

[0037] The pump housing is the lower part of the housing 1, and the pump chamber 17 is located below the grinding chamber 11, which is equivalent to integrating the pump housing on the food waste disposer. The driving mechanism 3 includes a driving member 31 and a first output shaft 32 and a second output shaft 33 connected to the driving member 31. The driving member 31 can be a motor, which is arranged between the pump chamber 17 and the grinding chamber 11. The first output shaft 32 is connected to the impeller 5, and the second output shaft 33 is connected to the grinding disc 2. This structure is simple, and the grinding disc 2 and the impeller 5 share a set of driving mechanisms 3.
