[0085] Combine the following Figures 1 to 4 A food residue treatment device for a dishwasher and a dishwasher of the present application are described in detail.

[0086] See also Figure 1 and Figure 2 In a first aspect of the present application, a food residue treatment device for a dishwasher is provided, wherein the dishwasher may generally include a housing 1 and a controller 2, wherein the controller 2 is mounted on the housing 1, and a water outlet is provided at the bottom of the housing 1. The food residue treatment device 4 may generally include a crushing mechanism 41, a backflow mechanism 42, and a shell mechanism 3. The shell mechanism 3 is disposed at the bottom of the housing 1 and corresponds to the water outlet, the crushing mechanism 41 is mounted in the shell mechanism 3 and is respectively connected to the controller 2 and the water outlet, and is used to crush the food residue entering the crushing mechanism 41, the backflow mechanism 42 is located in the shell mechanism 3 and is respectively connected to the crushing mechanism 41 and the controller 2, and the backflow mechanism 42 is configured to filter out larger food residues from the crushed food residues and to make the larger food residues flow back to the crushing mechanism 41, so that the crushing mechanism 41 can crush the larger food residues again.

[0087] The food residue treatment device for a dishwasher of the present application has a shell mechanism 3 for installing a crushing mechanism 41 and a backflow mechanism 42. The crushing mechanism 41 can crush the incoming food residues, and the backflow mechanism 42 can crush the larger food residues filtered out from the food residues again and discharge them. Therefore, no food residues will remain at the water outlet of the dishwasher, which can prevent the food residues from spoiling and producing bacteria, and contaminating the washed tableware. At the same time, it will not block the drain, and there is no need to manually clean the filter net after each cleaning, thereby improving the user experience.

[0088] In this embodiment, the dishwasher is an existing dishwasher, the cabinet 1 and the controller 2 are also existing, and the controller 2 stores a corresponding control program, which is existing and will not be described in detail here. The controller 2 and the crushing mechanism 41 and the reverse flow mechanism 42 are all connected in communication, and are used to control the operation of the crushing mechanism 41 and the reverse flow mechanism 42.

[0089] See also Figure 2 In the preferred embodiment of the food residue treatment device for a dishwasher, the backflow mechanism 42 generally includes a four-way pipe 421, a backflow pipe 422, a water inlet pipe 423 and a filter 424. The four-way pipe 421 has a first branch pipe 4211, a second branch pipe 4212, a third branch pipe 4213 and a fourth branch pipe 4214. The first branch pipe 4211 and the fourth branch pipe 4214 are arranged opposite to each other, and the second branch pipe 4212 and the third branch pipe 4213 are arranged opposite to each other. The bottom of the crushing mechanism 41 is connected to the first branch pipe 4211, so that the washing water and the food residue processed by the crushing mechanism 41 are discharged from the crushing mechanism 41. The filter 424 is installed inside the four-way pipe 421 and located above the fourth branch pipe 4214, and is used to filter the food residue processed by the crushing mechanism 41 entering the four-way pipe 421, so that the larger food residues in the food residue processed by the crushing mechanism 41 stay on the filter 424. One end of the reflux pipe 422 is connected to the second branch pipe 4212, and the other end of the reflux pipe 422 is connected to the side of the crushing mechanism 41. One end of the water inlet pipe 423 is connected to the third branch pipe 4213, and is used for clean water to enter the cross-tube 421, so as to flush the larger food residues on the filter screen 424 into the inside of the reflux pipe 422 and flow back to the crushing mechanism 41. When the food residue processing device 4 is not started, the food residue can first enter the crushing mechanism 41. At this time, the crushing mechanism 41 is not started, and the food residues smaller than the mesh of the filter screen 424 can be directly discharged.

[0090] In this embodiment, food residues with a diameter of less than 5 mm are food residues that can normally pass through the mesh of the filter 424, and larger food residues refer to food residues with a diameter of more than 5 mm, which cannot pass through the mesh of the filter 424.

[0091] Specifically, food residues and washing water enter the cross-pipe 421 from the first branch pipe 4211 and are filtered out through the filter 424. Food residues larger than the mesh size of the filter 424 will be retained on the filter 424. Clean water from the water inlet pipe 423 enters the cross-pipe 421 from the third branch pipe 4213 and flushes the food residues retained on the filter 424, i.e., larger food residues, into the second branch pipe 4212 and into the reflux pipe 422 until it enters the crushing mechanism 41 so as to be crushed again and discharged, thereby avoiding the problem of residual food residues.

[0092] In this embodiment, the length and thickness of the first branch pipe 4211, the second branch pipe 4212, the third branch pipe 4213 and the fourth branch pipe 4214 can be determined according to actual needs. The filter screen 424 can be installed inside the four-way pipe 421 in a clamping form, or it can be integrally formed. One end of the backflow pipe 422 is connected to the second branch pipe 4212 through a thread and a sealing gasket, and the other end of the backflow pipe 422 is connected to the side of the crushing mechanism 41 through a thread and a sealing gasket. One end of the water inlet pipe 423 is connected to the third branch pipe 4213 through a thread and a sealing gasket, and the other end of the water inlet pipe 423 is connected to the water inlet pipeline in the dishwasher through a thread and a sealing gasket, so that clean water enters the four-way pipe 421.

[0093] See also Figure 2 In the preferred embodiment of the food residue treatment device for a dishwasher, the reflux pipe 422 is an arc-shaped pipe, so that larger food residues will not be stuck in the reflux pipe 422, making it easier for larger food residues to pass.

[0094] See also Figure 2 In the preferred embodiment of the food residue treatment device for a dishwasher, the second branch pipe 4212 is inclined downwardly toward the four-way piece 421 to reduce resistance and help larger food residues slide into the reflux pipe 422 .

[0095] Continue reading Figure 2 In the preferred embodiment of the food residue treatment device for a dishwasher, the third branch pipe 4213 is inclined upwardly toward the four-way piece 421 so that the clean water increases the impact force to slide the larger food residue into the reflux pipe 422.

[0096] Continue reading Figure 2In the preferred embodiment of the food residue treatment device for a dishwasher, the backflow mechanism 42 further includes a first one-way valve 425, a second one-way valve 426 and a third one-way valve 427.

The box body 31 is arranged at the bottom of the box body 1, and the interior of the box body 31 is a cavity 32, which is used to set the crushing mechanism 41 and the backflow mechanism 42. The opening 33 is opened at the top of the box body 31 and corresponds to the bottom water outlet of the box body 1, so that the water outlet is connected to the crushing mechanism 41, so that washing water and food residues enter the crushing mechanism 41. The four through holes 34 are opened at the bottom of the box body 31, so that the fourth branch pipe 4214 extends out of the cavity 32. The upper end of the drain pipe 35 is connected to the fourth branch pipe 4214, so that the washing water and food residues are discharged, and the food residues after the larger food residues are crushed again are discharged.

[0099] Specifically, the box body 31 and the bottom of the box body 1 can be integrally formed or connected by threads or screws. The box body 31 is cylindrical and made of stainless steel or plastic. The shape of the opening 33 is adapted to the shape of the water outlet and is slightly larger than the size of the water outlet so that the upper end of the cylinder 411 is connected to the water outlet. The upper end of the sewage pipe 35 is connected to the fourth branch pipe 4214 in a threaded form.

The lower cover 413 is fixed to the lower end of the cylinder 411, and a second through hole 4113 is provided on the side of the lower cover 413 for sealingly connecting with the first branch pipe 4211, and a third through hole 4114 is provided in the middle of the lower cover 413. The crushing assembly 416 is installed below the lower cover 413 and extends inside the cylinder 411, and is used to crush food residues and crush the filtered larger food residues again.

[0101] Specifically, the barrel 411 is a cylinder, the upper end of which is sealed to the water outlet by threads and sealing gaskets, the first through hole 4111 and the other end of the reflux pipe 422 are connected by threads and sealing gaskets, and the lower cover 413 and the lower end of the barrel 411 are integrally formed.

[0102] In this embodiment, the upper cover 412 is arc-shaped, and the curvature of the upper cover 412 is consistent with the curvature of the cylinder 411. When the upper cover 412 is opened, the upper cover 412 and the inner wall of the cylinder 411 fit together, which is conducive to the entry of washing water and food residues into the cylinder 411 and avoids obstruction.
