In one embodiment, the backflow hole 321 is a circular hole, and the size of the backflow hole is matched with that of the large-particle kitchen waste, so that the large-particle kitchen waste can pass through the backflow hole; in another embodiment, as shown in fig. 4, the backflow hole 321 is a tapered hole with a small top and a large bottom, and the top end of the backflow hole is open to allow large particles of kitchen waste to pass through, and due to the tapered hole, the large particles of kitchen waste below the backflow hole 321 can more conveniently pass through after the water flow is agitated; preferably, the size of the upper opening of the backflow hole 321 is 1.1 to 1.5 times the diameter of the filtering hole 40.

Furthermore, in order to prevent large particles of kitchen garbage above the grinding plate 32 from directly entering the lower part of the grinding plate 32 through the backflow hole 321 and improve the efficiency of re-grinding, a one-way guide sleeve 322 is further arranged in the backflow hole 321. As shown in fig. 5 and 6, the one-way guide sleeve 322 is in a cone ring shape, and is provided with an upper opening 3220 with a size smaller than or equal to that of the small-particle kitchen waste and a lower opening 3221 with a larger size, wherein the size of the lower opening 3221 is at least larger than that of the large-particle kitchen waste. The unidirectional guide sleeve 322 is further provided with a deformation groove 3223 penetrating the upper end and the lower end thereof. The one-way guide sleeve 322 is made of an elastic material such as a thin steel sheet or a rubber sheet, and can be elastically deformed after being pressed, so that the size of the upper opening 3220 is increased or decreased. When the stirred water flow passes through the inside of the one-way guide sleeve 322 from bottom to top, the water flow in the one-way guide sleeve 322 drives the one-way guide sleeve 322 to be opened, so that the upper opening is enlarged, and large-particle kitchen waste can pass through the one-way guide sleeve 322 from bottom to top; on the contrary, when rivers were from last down through one-way guide pin bushing 322, rivers will extrude one-way guide pin bushing 322 outer wall, make upper shed 3220 size diminish to the rubbish from cooking of messenger's top can't remove to the below from one-way guide pin bushing 322, only can get into grinding component 3 below after the grinding, has guaranteed that big granule rubbish from cooking can be ground once more, thereby improves grinding effect.

Preferably, the size of the one-way guide sleeve 322 is slightly smaller than that of the backflow hole 321 to facilitate the size change thereof.

As shown in fig. 5, a limiting boss 3210 protruding inward is further disposed below the backflow hole 321, so as to limit the position of the one-way guide sleeve 322. The upper end of the grinding disc 32 is also provided with a concave hole 323 communicated with the reflux hole 321, the upper end of the one-way guide sleeve 322 extends into the concave hole 323, and the outer wall of the one-way guide sleeve 322 can be conveniently extruded by water flow from top to bottom, so that the size of the upper opening 3220 is reduced.

In this application, the rotation direction of the rotating shaft 30 is defined as forward rotation and the direction opposite to the rotation direction is defined as reverse rotation during normal grinding operation. Further, the paddle 51 is configured to: when the water flow is driven by the paddle 51 to move from top to bottom in the forward rotation, and when the water flow is driven by the paddle 51 to move from bottom to top in the reverse rotation.

This has the advantage of enabling the water flow within the grinding chamber 12 to be more directional. During normal grinding, the disturbance of the water flow is complicated, but the forward rotation paddle 51 can provide a downward flowing force to the water flow, so that the forward rotation paddle can press the one-way guide sleeve 322 to reduce the upper opening 3220, so that kitchen waste above can be prevented from directly passing through the one-way guide sleeve 322, and meanwhile, small particles of kitchen waste can more quickly pass through the filter disc 4 and can be discharged from the connecting port 100; when the large-particle kitchen garbage is needed to be ground again, the motor rotates reversely, the water flow upwards props the upper opening 3220 of the one-way guide sleeve 322 open, so that the large-particle kitchen garbage can directly pass through the one-way guide sleeve 322, and the working efficiency is improved.

It will be appreciated that when it is desired to return large particles of kitchen waste to the grinding assembly 3, a sufficient amount of water is required in the grinding chamber 12 to move the large particles of kitchen waste above the grinding assembly 3, and typically the level of water in the grinding chamber 12 should be higher than the grinding assembly 3. When the liquid level needs to be increased, the water valve 101 is only required to be closed, and water is added into the crushing cavity 12. A liquid level sensor is arranged in the shell 10, whether the liquid level meets the requirement can be detected, and when the liquid level does not meet the requirement, the control system can remind a user in the modes of sound and light and the like. It can be understood that the control of the liquid level height can be controlled by the cooperation of the water tap and the water valve 101 above the water tank, and when the water tap and the water valve 101 are both electrically controlled, the control system can automatically control the water tap and the water valve 101 to be opened or closed, so as to automatically adjust the liquid level; of course, a water inlet may be additionally provided on the main body 1, and the water inlet is controlled by the electric valve, so that the liquid level is automatically adjusted by controlling the opening and closing of the electric valve and the water valve 101.

In order to make the water flow better, as shown in fig. 2, a plurality of first guiding holes 112 are formed in the installation ring body 110 at positions above the grinding ring 31, and the first guiding holes 112 have the same size as the filtering holes 40, so that only small particles of kitchen waste can pass through. As shown in fig. 7, a plurality of second guide holes 113 are formed in the mounting base 111, and kitchen waste that can pass through the second guide holes 113 is small-sized kitchen waste due to the filtering of the first guide holes 112 and the filtering holes 40, and thus the size of the second guide holes 113 is not limited. The arrangement is such that when the paddle 51 is reversed, the water flow can go up through the grinding disc 32 and then go back to the bottom after passing through the first diversion hole 112 and the second diversion hole 113 in sequence, and the directionality is better.

The kitchen garbage disposer can alternately carry out forward rotation and reverse rotation when working, so that kitchen garbage can be ground more fully and completely, and the risk of blocking a drainage pipeline is reduced.

The kitchen garbage disposer at least has the following advantages:

3. the stirring piece can drive water to move towards different directions when the rotation directions of the motor are different, and can drive small-particle kitchen garbage to pass through the filter disc more quickly when the water is driven to move downwards; when ordering about rivers rebound, can be faster order about big granule rubbish from cooking through one-way guide pin bushing to improve work efficiency.

The above description is only for the purpose of illustrating embodiments of the present invention and is not intended to limit the scope of the present invention, and all modifications, equivalents, and equivalent structures or equivalent processes that can be used directly or indirectly in other related fields of technology shall be encompassed by the present invention.
