Description

Technical Field

[0001] The present invention relates to the field of garbage disposal, and in particular to a kitchen waste disposer and a kitchen waste disposal system. Background Art

[0002] With the implementation of garbage classification, the sales of classified garbage bins and garbage disposers have greatly increased, and kitchen waste disposers have also been purchased and used by more and more customers. Kitchen waste is crushed and discharged directly into the sewer, which brings certain convenience to customers.

[0003] For example, the kitchen waste treatment device disclosed in the utility model patent "A kitchen waste treatment device with deodorization function" with patent application number CN201721771010.0 (authorization announcement number CN207959388U) has a grinding chamber on the top of the body, and a filter hole, a grinding hammer and a grinding ring are provided in the grinding disc. This kitchen waste disposer has only one grinding chamber, and the kitchen waste is ground into fine particles by the grinding disc in the grinding chamber and discharged into the sewer. This kitchen waste disposer has a contradiction between the grinding fineness and the drainage speed. If the gap between the grinding disc and the grinding ring is controlled to be very small, although the grinding effect will be finer, on the one hand, the dynamic balance requirements of the grinding disc are increased, and on the other hand, the drainage speed and grinding rate are also affected. If the gap between the grinding disc and the grinding ring is controlled to be larger, it will directly lead to a deterioration in the grinding fineness, and large particles of kitchen waste entering the sewer will increase the risk of blockage.

[0004] If two grinding chambers are provided, if the garbage processed by the two grinding assemblies is discharged at the same time, the sewer is easily blocked, and the discharged sewage may return to the other grinding chamber. Once the drainage is blocked, it will cause the user to be unable to use the kitchen waste disposer normally or even the sink. Summary of the invention

[0027] The first motor 8 is installed between the first grinding chamber 1 and the strong exhaust chamber 3. The first motor 8 has a vertically arranged output shaft 81, which is in the form of a shaft with two ends. The first motor 8 drives the first grinding assembly 4 and the first pump wheel 6 to rotate synchronously. The upper end of the output shaft 81 extends into the first grinding chamber 1. The first grinding assembly 4 includes a grinding ring 41, a first grinding disc 42 and a grinding hammer 43 for processing kitchen waste. The first grinding disc 42 is installed at the upper end of the output shaft, and a second pump wheel 44 is provided below the first grinding disc 42 to achieve crushing and grinding of kitchen waste.

[0028] The lower end of the output shaft 81 extends into the forced discharge chamber 3, and the first pump wheel 6 is installed at the lower end of the output shaft 81. The first pump wheel 6 has a certain degree of suction effect, so that the wastewater can enter the kitchen waste disposer more smoothly, and the first pump wheel 6 also has a forced discharge effect, which is conducive to improving the anti-blocking ability.

[0029] A boss 2a is formed at the bottom of the second grinding chamber 2, and the second grinding assembly 5 includes a second grinding disc 51 for grinding finely crushed residues, a cutter disc 52 for crushing the residues again, an outer rotor 53, an inner rotor 54, a second motor 55, a driven permanent magnet 56, an active permanent magnet 57 and a bearing 58 to grind the finely crushed residues.

[0030] The second grinding disc 51 has a water filter hole, and the blade disc 52 is arranged below the second grinding disc 51. The blade disc 52 includes a chassis 521 and a blade 522. The blade 522 is twistedly arranged on the disc surface of the chassis 521. The outer rotor 53 is arranged above the boss 2a.

[0032] The trap structure can effectively prevent the odor of the sewer from returning to the kitchen waste disposer. The grinding time in the second grinding chamber 2 can be increased by adopting a water storage working mode, the grinding effect can be enhanced, and the treated sewage can be prevented from pouring into the second grinding chamber 2, so as to achieve the effect of water seal isolation. When the trap structure is filled with water, the water level continues to rise, and a siphon effect can be formed. The wastewater in the second grinding chamber 2 enters the forced discharge chamber 3 through the connecting pipe 7 and is discharged through the first pump wheel 6. Under normal circumstances, the water level height of the water storage in the second grinding chamber 2 is the same as the height of the partition 7d. When the first grinding assembly 4 is working, the discharged sewage will flow along the connecting pipe 7 under the forced discharge action of the second pump wheel 44, part of which will quickly pour into the first vertical part 7b and the horizontal part 7a, and the other part will pour into the forced discharge chamber 3 and be discharged through the first pump wheel 6; when the first vertical part 7b is connected to the sewage in the forced discharge chamber 3, the water in the second grinding chamber 2 is quickly sucked under the action of the first pump wheel 6, so as to realize the rapid discharge of sewage in the second grinding chamber 2.

The feeding port 9a has a size of 100-150 mm, and the drainage port 9b is used to drain water and discharge fine kitchen waste. The feeding port 9a is connected to the first feeding port 11 of the kitchen waste disposer, and the drainage port 9b is connected to the second feeding port 21 of the kitchen waste disposer.

[0034] The bottom of the water tank 9 has a step 91, the feeding port 9a is arranged on a first horizontal plane 911 above the step 91, and the drain port 9b is arranged on a second horizontal plane 912 below the step 91. A filter basket 10 is provided at the connection between the second grinding chamber 2 and the drain port 9b of the water tank 9. The feeding port 1a is provided with a feeding cover 92 for covering the feeding port 1a. When the user needs to feed, the feeding cover 92 is opened, and the whole plate can be directly fed, which greatly improves the convenience of feeding and the user experience. After opening the feeding cover 92, the machine cannot run, which ensures safety and prevents kitchen waste from splashing.
