Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of dishwashing sinks, in particular to a commercial dishwashing sink. Background Art
[0002] Commercial sinks are commonly used in commercial environments such as restaurants and hotels, and need to handle large quantities of tableware and kitchen utensils, which often have a large amount of food residue attached to them. Compared with household sinks, they handle more tableware, and more food residue is more likely to clog the filter. Currently, common sinks all install filters at the drain outlet to filter food residue. When a large amount of residue clogs the filter, the drainage of the sink will be slow or even stop. In order to drain faster, cleaning staff will usually reach into the sewage in the sink and lift the filter to a certain height, creating a certain gap between the filter and the drain hole, so that the sewage can pass quickly through this gap. At this time, some food residue will be carried away by the water flow, which can easily cause blockage of the downstream drainage pipe.
[0003] Based on the above situation, we designed a commercial dishwasher to solve the above problems. Utility Model Content
[0004] The utility model provides a commercial dishwashing sink, which solves the problem in the prior art that the downstream drainage pipe is easily blocked when the commercial dishwashing sink is draining.
[0005] The technical problem solved by the present invention is achieved by the following technical solutions:

[0007] A push-up assembly is located below the filter hopper and is used to generate an upward force on the filter hopper from below, so that a certain gap is created between the filter hopper and the input end of the drain pipe to allow water to pass through quickly;
[0008] A collecting hopper, used to filter food residues not intercepted by the filtering hopper;
[0009] A linkage member is connected between the pushing assembly and the collecting bucket, and drives the collecting bucket to move synchronously with the movement of the pushing assembly. When the pushing assembly pushes the filter bucket upward, the linkage member drives the collecting bucket to move to just below the filter bucket.
[0010] Preferably, the pushing assembly includes a push tube connected to the drain pipe and a pressure rod provided below the filter bucket, the interior of the push tube is slidably connected to an extrusion piece, and one end of the extrusion piece is provided with an extrusion bevel for extruding the pressure rod.

DETAILED DESCRIPTION
[0026] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below with reference to specific illustrations.
[0027] A commercial dishwashing sink, such as Figure 1 As shown, it is a structural diagram of the prior art, including a pool body 1 and a drain pipe 11 arranged under the pool body 1. At the input end of the internal drain pipe 11 of the pool body 1, a filter hopper 12 for filtering food residues is provided. In order to store water in the pool body 1, a cover plate 13 can be provided on the filter hopper 12 as needed. When the cover plate 13 is covered on the filter hopper 12, the filter hopper 12 is blocked at the top, and water can be stored in the pool body 1. When the cover plate 13 is removed, the water in the pool body 1 can be discharged into the drain pipe 11 through the filter hopper 12, and the food residue and other impurities in the water are filtered by the filter hopper 12 to avoid being discharged into the drain pipe 11 with the water flow and causing blockage. In some large kitchens and other places of use, more food residues such as tableware are processed than in ordinary household dishwashing sinks. , more residues accumulate on the filter bucket 12, which will cause the drainage effect of the filter bucket 12 to deteriorate. In order to drain the sewage in the pool body 1 as soon as possible, the staff needs to reach into the sewage in the pool body 1 to touch the filter bucket 12, and then lift the filter bucket 12 to a certain height so that there is a certain gap between the filter bucket 12 and the drain pipe 11 for sewage to be discharged. In this process, the lifting height of the filter bucket 12 is greatly affected by the subjective influence of the operator. Once the lifting height of the filter bucket 12 is large, the gap between the filter bucket 12 and the drain pipe 11 is large, and some larger food residues and other solid impurities in the sewage are discharged into the drain pipe 11 along with the water flow, causing blockage. If the lifting height is low and the gap is small, the drainage efficiency may be low. Therefore, the present invention makes the following improvements to the above problems:
[0028] like Figure 2-8As shown, a pushing assembly is provided below the filter bucket 12, which is used to generate an upward force on the filter bucket 12 from below, so that a certain gap is generated between the filter bucket 12 and the input end of the drain pipe 11 for water to pass through quickly. A hollow collecting bucket 2 is also provided below the filter bucket 12. The collecting bucket 2 can adopt the same filter screen structure as the filter bucket 12, etc., and is used to filter the food residues not intercepted by the filter bucket 12 again, so as to avoid the food residues passing through the gap between the filter bucket 12 and the drain pipe 11 from entering the drain pipe 11 and causing blockage. A linkage part 3 is provided between the pushing assembly and the collecting bucket 2. The linkage part 3 can drive the collecting bucket 2 to move synchronously with the movement of the pushing assembly, and when the pushing assembly pushes the filter bucket 12 to move upward, the linkage part 3 drives the collecting bucket 2 to move to the bottom of the filter bucket 12 for secondary filtration of the food residues dropped from above.
[0029] Specifically, such as Figure 6-7 As shown, the jacking assembly includes a pushing tube 4 connected to the drain pipe 11 and a pressure rod 41 provided under the filter bucket 12. The pushing tube 4 is slidably connected to the inside of the pushing tube 4, and one end of the squeezing member 42 is provided with an squeezing inclined block 43 for squeezing the pressure rod 41. The lower end of the pressure rod 41 is provided with an inclined surface parallel to the inclined surface of the squeezing inclined block 43. When the pushing extrusion member 42 drives the squeezing inclined block 43 to move in the direction of the pressure rod 41, the inclined surface of the squeezing inclined block 43 conflicts with the inclined surface on the pressure rod 41, and as the squeezing member 42 drives the squeezing inclined block 43 to continue to move, the pressure rod 41 is subjected to the force of the squeezing inclined block 43 to move upward, and drives the filter bucket 12 to slide upward in the drain pipe 11. When the squeezing member 42 extends to the pushing tube 4 When one end of the outer side collides with one end of the push tube 4, the extrusion piece 42 can no longer drive the extrusion bevel 43 to collide with the pressure rod 41. At this time, the height of the filter bucket 12 being lifted reaches the maximum value. At this time, the sewage and food residues in the pool body 1 will pass through the gap between the filter bucket 12 and the drain pipe 11 to increase the drainage speed in the pool body 1. In order to improve the stability of the filter bucket 12 when being pushed, the pressure rod 41 can be provided with a guide rod 46 that is slidably connected to the inner wall of the drain pipe 11 to guide the filter bucket 12 when it is pushed upward so that the filter bucket 12 will not fall over. The extrusion piece 42 is installed on the outside of the pool body 1. The operator can operate from the outside of the pool body 1 without having to put his hands into the sewage inside the pool body 1 to operate, which is more convenient.
[0030] Further, such as Figure 6As shown, in order to facilitate the resetting of the extrusion member 42, a raised ring 44 is provided on the outer wall of the extrusion member 42, and a spring 45 is connected between the raised ring 44 and the inner wall of the push tube 4. After the extrusion member 42 is pushed to drive the extrusion bevel 43 to contact the pressure rod 41, the pushing force on the extrusion member 42 is released, and the extrusion member 42 and the extrusion bevel 43 can be driven to reset under the action of the spring 45, so that the extrusion bevel 43 moves into the push tube 4.
[0031] Among them, Figure 7-8 As shown, a receiving box 6 for accommodating the collecting bucket 2 is provided below the drain pipe 11. When the extrusion member 42 is reset, the collecting bucket 2 will be driven to move out of the drain pipe 11 through the linkage member 3. At this time, the collecting bucket 2 is located in the receiving box 6. The bottom of the receiving box 6 is detachably connected to a first blocking cover 61, and the bottom of the collecting bucket 2 is detachably connected to a second blocking cover 62. The receiving box 6 can be made of a transparent material. When it is observed that the food residue collected in the collecting bucket 2 reaches a certain amount, the first blocking cover 61 and the second blocking cover 62 can be removed to discharge the filtered residue in the collecting bucket 2. The preferred detachable connection method is a threaded connection to improve the sealing effect and prevent the moisture in the receiving box 6 from leaking out from the bottom outlet.
[0032] Further, such as Figure 8 As shown, a guide groove 7 is provided on the inner wall of the bottom of the storage box 6, and the guide groove 7 is gradually inclined downward from the storage box 6 to the drain pipe 11. When the collecting bucket 2 moves from the drain pipe 11 to the storage box 6, a certain amount of water will remain in the collecting bucket 2 and gradually drain out. The drained water can flow into the drain pipe 11 through the guide groove 7, avoiding the drained water from remaining in the storage box 6.
[0033] Among them, Figure 5 as well as Figure 7 As shown, one end of the linkage part 3 passes through the accommodating box 6 and is slidably connected to the accommodating box 6. A slide groove 31 for the linkage part 3 to slide is also provided at the bottom of the pushing tube 4. A sealing part 5 is provided on the inner wall of the pushing tube 4. The sealing part 5 can be made of rubber or other materials. The extrusion part 42 passes through the sealing part 5 and is slidably connected to the sealing part 5 to prevent water in the drain pipe 11 from leaking from the slide groove 31 and reduce sewage leakage. At the same time, the linkage part 3 may include a first rod body 32 connected to the extrusion part 42 and a second rod body 33 threadedly connected to the collecting bucket 2. The first rod body 32 and the second rod body 33 are rotatably connected. A box door is also provided on the accommodating box 6. After removing the second rod body 33 from the filter bucket 12, the box door can be opened to remove the filter bucket 12 from the accommodating box 6, thereby facilitating operations such as cleaning the interior of the filter bucket 12.
