Technical Field

The utility model relates to the technical field of dishwashers, in particular to a slag-removing dishwasher.

Background Art

A dishwasher is a device that automatically washes tableware such as bowls, chopsticks, plates, dishes, knives, forks, etc. The fully automatic dishwashers on the market can be divided into two categories: household and commercial. Household fully automatic dishwashers are only suitable for families, and they are mainly cabinet-type, table-top, sink-integrated and integrated.

In order to facilitate the cleaning of food residues and avoid food residues clogging the sewer, existing dishwashers are equipped with a crusher inside the dishwasher. The crusher is used to crush the food residues in the dishwasher, and then the crushed food residues are discharged into the sewer, so that the cleaning frequency of the dishwasher can be reduced, and at the same time, the food residues can be prevented from being discharged into small waterways and causing blockage. However, this type of dishwasher that can clean food residues has the following problems: First, when the crusher crushes the food residues, the food residues are easily thrown out of the crusher and thrown onto the dish box of the dishwasher or even onto the dishes under the high-speed rotation of the crusher's blades, affecting the cleanliness of the inside of the dishwasher. Second, after the crusher crushes the food residues, a lot of residues remain on the inner wall of the crusher, which is easy to cause bacteria to grow, and thus is also easy to affect the cleanliness of the dishwasher. Third, the thickness of the filter causes the food residues to get stuck on the filter holes.

Utility Model Content

The utility model is intended to provide a residue-removing dishwasher, so as to solve the problem that the existing dishwasher may cause the food residues to splash and adhere to the dish box of the dishwasher or even the dishes when cleaning the food residues in the dishwasher.

In order to solve the above technical problems, the utility model provides the following technical solutions: a descumming dishwasher, comprising a machine body and a cleaning mechanism, wherein a control system is provided in the machine body, an inclined bottom plate is fixedly connected in the machine body, a water inlet is provided at the lowest point of the bottom plate, a water pump cavity is provided below the bottom plate, a water pump is fixedly connected in the water pump cavity, a vertical water guide pipe is fixedly connected to the water outlet of the water pump, the top end of the water guide pipe passes through the bottom plate and is located above the bottom plate, and a spray arm for spraying water to wash dishes is rotatably connected to the top end of the water guide pipe;

The cleaning mechanism comprises a cleaning and crushing bin, which is located in the water pump cavity, the top of the cleaning and crushing bin is open, and the opening of the cleaning and crushing bin is connected to the water inlet, the opening of the cleaning and crushing bin is detachably connected with a shrinking annular cover ring, and the annular cover ring is located in the cleaning and crushing bin, the inner bottom of the cleaning and crushing bin is detachably connected with a filter screen for filtering food residues, the bottom of the cleaning and crushing bin is fixedly connected with a slag water bin, the slag water bin is connected with the cleaning and crushing bin, the inner bottom of the slag water bin is provided with a closed motor bin, a motor is fixedly connected in the motor bin, the output shaft of the motor vertically passes through the filter screen and is located in the cleaning and crushing bin, and a crushing blade is detachably connected to the output shaft of the motor;

Two opposite sides of the slag water bin are respectively provided with water holes, one of which is connected with the water pump chamber and is provided with a second solenoid valve, and the other water hole is provided with a first solenoid valve, and the first solenoid valve and the second solenoid valve are both connected with the control system electrical signal, the first solenoid valve is connected with a drain pipe, and the drain pipe is connected with a water pump, the water outlet of the water pump is connected with the sewer, and the water pump is connected with the control system electrical signal.

The working principle of the utility model is as follows: when in use, the control system of the dishwasher controls the injection of clean water into the machine body, and the clean water flows into the cleaning and crushing bin through the water inlet along the inclined bottom plate in the machine body, and then flows into the water pump cavity along the water through hole of the cleaning and crushing bin. When the water pump in the water pump cavity is running, the clean water in the water pump cavity is pumped into the spray arm through the water guide pipe, so that the spray arm rotates and sprays water under the action of water pressure, and the dishes in the machine body can be rinsed. During the dishwashing process, food residues flow into the cleaning and crushing bin along the inclined bottom plate through the water inlet with the dishwashing water. Since a filter screen plate for filtering food residues is detachably connected to the bottom of the cleaning and crushing bin, the food residues are blocked by the filter screen plate and remain in the cleaning and crushing bin, and the filtered dishwashing water flows into the water pump cavity through the water through the water through hole again for secondary circulation.

When the dishes are washed, the control system opens the first electromagnetic valve and starts the water pump. At this time, the dishwashing water flowing out of the cleaning and crushing bin is discharged into the sewer through the operation of the water pump. When the liquid level of the dishwashing water is at the appropriate position of the cleaning and crushing bin, the control system controls the first electromagnetic valve to close, and the drainage is stopped at this time. Then the motor is started. When the motor is running, the crushing blade is driven to rotate through the output shaft. When the crushing blade rotates, the food residue in the cleaning and crushing bin is crushed. In the process of crushing the food residue, since the opening of the cleaning and crushing bin is detachably connected with a shrinking annular cover ring, the crushing blade rotates, and the splashing food residue is blocked by the annular cover ring and cannot fly into the machine body from the opening of the cleaning and crushing bin. When the food residue is crushed to a particle size that can pass through the filter screen, the food residue enters the slag water bin through the filter screen, and then the first electromagnetic valve is opened and the water pump is started. Through the operation of the water pump, the crushed food residue and dishwashing water in the cleaning and crushing bin and the slag water bin are pumped out and discharged into the sewer.

The beneficial effects of the utility model are as follows: the scheme arranges a tapered annular cover ring, so that when the dishwasher is in operation, the hole at the center of the annular cover ring will not hinder the dishwashing water and food residues from entering the cleaning and crushing bin, and in the process of crushing the food residues, the crushing blade rotates so that the dishwashing water and food residues will only splash obliquely along the direction of rotation of the crushing blade, and will not splash vertically. Therefore, the tapered annular cover ring blocks the water inlet, and the obliquely splashing dishwashing water and food residues are just blocked by the annular cover ring, so that they cannot splash into the dish box through the water inlet.

Furthermore, the annular cover ring is threadedly connected to the cleaning and crushing bin. The purpose is to facilitate the disassembly of the annular cover ring for manual cleaning through this arrangement.

Furthermore, the upper part of the cleaning and crushing bin is cylindrical, and a groove is provided on the inner wall of the cleaning and crushing bin, and the groove extends from bottom to top in a spiral shape to the top of the cleaning and crushing bin, and a cleaning nozzle is fixedly connected to the bottom of the groove, and the water spray port of the cleaning nozzle faces the extension direction of the groove, and the cleaning nozzle is connected to the control system by electrical signals, and the cleaning nozzle is connected to the water inlet pipe of the dishwasher. The purpose is that after the crushing blade crushes the food residue, the food residue will adhere to the inner wall of the cleaning and crushing bin, so through this setting, the cleaning nozzle is controlled by the control system to open, and the water sprayed from the cleaning nozzle will flow upward along the spiral groove under the action of water pressure, and then the food residue on the inner wall of the crusher shell will be washed away.

Furthermore, the filter screen plate is in the shape of a truncated cone. The purpose is to increase the area of the filter screen plate by setting the filter screen plate in the shape of a truncated cone, so as to facilitate the rapid passage of dishwashing water and increase the filtering efficiency.

Furthermore, the filter holes of the filter screen plate are in the shape of a cone with a small top and a large bottom, and the edges of the filter holes of the filter plate are provided with cutting edges. The purpose is that this arrangement can make the food residues in the cleaning and crushing bin rotate with the water flow, and when the food residues contact the filter holes during the rotation process, the edges of the filter holes can cut the food residues because they are provided with cutting edges, thereby accelerating the crushing efficiency.

The cleaning mechanism includes a cleaning and crushing bin 14, which is located in the water pump chamber 4. The cleaning and crushing bin 14 is cylindrical and the top of the cleaning and crushing bin 14 is open, and the opening of the cleaning and crushing bin 14 is connected to the water inlet. A shrinking annular cover ring 15 is threadedly connected to the opening of the cleaning and crushing bin 14, and the baffle is located in the cleaning and crushing bin 14. The inner bottom of the cleaning and crushing bin 14 is detachably connected with a frustum-shaped filter screen plate 11. The filter hole 19 of the filter screen plate 11 is a frustum-shaped filter screen plate 11 with a small top and a large bottom. The edge of the filter hole 19 of the filter screen plate 11 is a cutting edge. The bottom of the cleaning and crushing bin 14 is fixedly connected with a slag and water bin 16, which is communicated with the cleaning and crushing bin 14. The inner bottom of the slag and water bin 16 is fixedly connected with a closed motor bin 18, and a motor 8 is fixedly connected in the motor bin 18. The output shaft of the motor 8 vertically passes through the filter plate 11 upward and is located in the cleaning and crushing bin 14. The output shaft of the motor 8 is detachably connected with a crushing blade 12, and the crushing blade 12 includes a transverse blade, both ends of the transverse blade are tilted and bent upward, and the upper surface of the transverse blade is fixedly connected with two mirror-symmetrical blades. A vertical blade, two downwardly inclined and mirror-symmetrical auxiliary blades are fixedly connected at both ends of the lower surface of the transverse blade, and the end of the auxiliary blade away from the transverse blade is bent and inclined upward; a groove 13 is provided on the inner wall of the cleaning and crushing bin 14, and the groove 13 extends spirally from bottom to top to the top of the cleaning and crushing bin 14, and a cleaning nozzle 17 is fixedly connected to the bottom of the groove 13, and the water spray port of the cleaning nozzle 17 faces the extension direction of the groove 13. The cleaning nozzle 17 is connected to the control system electrical signal, and the cleaning nozzle 17 is connected to the water inlet pipe of the dishwasher.

Two opposite sides of the slag water bin 16 are respectively provided with water holes, one of which is connected to the water pump chamber 4, in which a second solenoid valve 7 is installed, and the other water hole is provided with a first solenoid valve 9, both the first solenoid valve 9 and the second solenoid valve 7 are connected to the control system electrical signal, the first solenoid valve 9 is connected to a drain pipe 10, the drain pipe 10 is connected to a water pump, the water outlet of the water pump is connected to the sewer, and the water pump is connected to the control system electrical signal.

The specific implementation process is as follows:

When in use, the control system of the dishwasher controls the injection of clean water into the machine body 1, opens the second solenoid valve 7 and closes the first solenoid valve 9, and the clean water flows into the cleaning and crushing bin 14 through the water inlet along the inclined bottom plate 3 in the machine body 1, and then flows into the water pump chamber 4 along the water holes of the cleaning and crushing bin 14 and the slag water bin 16. When the water pump 6 in the water pump chamber 4 is running, the clean water in the water pump chamber 4 is pumped into the spray arm 2 through the water guide pipe 5. In this way, the spray arm 2 rotates and sprays water under the action of water pressure to rinse the dishes in the machine body 1. During the dishwashing process, food residues flow into the cleaning and crushing bin 14 along the inclined bottom plate 3 through the water inlet with the dishwashing water. Since a filter screen plate 11 for filtering food residues is detachably connected to the bottom of the cleaning and crushing bin 14, the food residues are blocked by the filter screen plate 11 and remain in the cleaning and crushing bin 14, and the filtered dishwashing water flows into the water pump chamber 4 through the water hole again for secondary circulation.

When the dishes are washed, the control system opens the first solenoid valve 9, closes the second solenoid valve 7, and starts the water pump. At this time, a part of the dishwashing water flowing out of the cleaning and crushing bin 14 is discharged into the sewer through the operation of the water pump. When the liquid level of the dishwashing water is at an appropriate position of the cleaning and crushing bin 14, the control system controls the first solenoid valve 9 to close, and the drainage is stopped at this time. Then the motor 8 is started. When the motor 8 is running, the crushing blade 12 is driven to rotate through the output shaft. When the crushing blade 12 rotates, the food residues in the cleaning and crushing bin 14 are crushed. In the process of crushing the food residues, since the opening of the cleaning and crushing bin 14 is threadedly connected with a shrinking annular cover ring 15, the splashing food residues caused by the rotation of the crushing blade 12 are blocked by the annular cover ring 15, and thus cannot fly into the machine body 1 from the opening of the cleaning and crushing bin 14. When the food residue is crushed to the point where it can pass through the mesh of the filter screen 11, the food residue passes through the filter screen and enters the slag water bin 16, and then the pump is started to pump the crushed food residue and dishwashing water in the cleaning crushing bin 14 out of the slag water bin 16 and into the sewer. At the same time, in the process of crushing the food residue, when the food residue in the cleaning crushing bin 14 rotates with the water flow, when the food residue contacts the filter hole 19 during the rotation, the edge of the filter hole 19 can cut the food residue because it is set as a cutting edge, thereby accelerating the crushing efficiency.

After the food residue is cleaned, the control system controls the cleaning nozzle 17 to open. After the cleaning nozzle 17 is turned on, clean water is sprayed out. Since the water spray port of the cleaning nozzle 17 is facing the extension direction of the groove 13, the clean water sprayed from the cleaning nozzle 17 flows along the spiral groove 13 from the bottom of the cleaning and crushing bin 14 to the top of the cleaning and crushing bin 14 under the action of water pressure, and then flushes away the food residues adhered to the inner wall of the cleaning and crushing bin 14 into the residue water bin 16, and enters the sewer through the first solenoid valve 9.
