Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of motors and water pumps, and more specifically, it relates to a dishwasher water pump with a cleaning effect. Background Technology
[0002] Early dishwashers had relatively simple water pumps, primarily functioning to deliver water into the washing chamber for initial rinsing of dishes. The dishwasher's humid working environment meant that the stator and rotor assemblies in the motor and pump were energized, posing risks of current leakage leading to electric shock and electric field distortion between the stator and rotor affecting normal motor operation. Reliable insulation and electric field stabilization measures were necessary. Furthermore, early water pumps had relatively low flow rates and pressures, making it difficult to thoroughly and effectively clean every corner, complex structural area, and pipe connections within the water chamber using only water flow. This resulted in poor removal of stubborn stains, impacting the overall cleaning efficiency and hygiene of the equipment.
[0003] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings to provide a dishwasher water pump with a cleaning effect, in order to achieve a more practical purpose. Utility Model Content
[0004] This invention provides a dishwasher water pump with a cleaning effect, which overcomes the above-mentioned defects in the prior art.
[0005] The purpose and function of this utility model, a dishwasher water pump with a stain removal effect, are achieved by the following specific technical means:
[0006] A dishwasher water pump with a decontamination effect includes: a stator assembly assembly, an upper tub assembly for water suction fixedly mounted on the stator assembly assembly, a drain pipe for draining water on the outside of the upper tub assembly, a sealing top cover assembly fixedly connected to the opening of the upper tub assembly to form a first cavity, an impeller assembly for cleaning scale installed in the first cavity, and an inlet pipe with an elastic and bendable effect connected to the sealing top cover assembly;
[0007] The sealing top cover assembly consists of a cover body and a heating tube, wherein the heating tube is used to effectively heat the water inside the first cavity;
[0008] The stator assembly and the upper barrel assembly are combined to form a second cavity. The second cavity is located below the first cavity. A rotatable rotor assembly is installed in the second cavity, and the output end of the rotor assembly extends into the upper barrel assembly.
[0009] In a further technical solution, the output end of the rotor assembly is fixedly connected to the impeller assembly, the impeller assembly includes impeller blades and a rotating sleeve, the rotating sleeve is rotatably mounted on the upper part of the impeller blades, and the end of the rotating sleeve is fixedly connected to the water inlet pipe.
[0010] In a further technical solution, the impeller blade includes an upper ring plate and a lower ring plate. The upper ring plate is disposed above the lower ring plate. A spiral cleaning plate is fixedly connected between the upper ring plate and the lower ring plate. A brush is provided on the outer side of the spiral cleaning plate, and the brush makes contact with the inner wall of the upper tank assembly.
[0011] In a further technical solution, a rotating blade is fixedly installed on the outer side of the rotating sleeve, and the rotating blade disturbs the interior of the first cavity when it rotates.
[0012] In a further technical solution, the stator assembly includes a plastic housing, inside which is a cavity, and a stator core is fixedly installed inside the cavity.
[0013] In a further technical solution, the rotor assembly includes a rotating shaft, a rotating bearing and a plastic filler ring are fixedly connected to the surface of the rotating shaft, and a rotor magnetic ring is fixedly installed on the outer side of the plastic filler ring.
[0014] In a further technical solution, a rotating blade is fixedly installed on the upper part of the rotor assembly. The rotating blade is installed through the first cavity and placed inside the impeller assembly. After the rotating blade rotates, it can increase the water flow adsorption inside the impeller assembly.
[0015] In a further technical solution, the plastic housing fully encloses and seals the stator core, and the plastic housing material is BMC material or thermoplastic injection molded.
[0016] In a further technical solution, the plastic filling ring is injection molded from BMC, PP, PBT and nylon materials.
[0017] Compared with the prior art, the present invention has the following beneficial effects:
[0018] This utility model discloses a dishwasher water pump with a cleaning effect. The stator assembly and rotor assembly are wrapped with a plastic shell. The plastic shell is a good electrical insulator, which can effectively isolate current and prevent current leakage to the outside, thereby avoiding the risk of electric shock to the user. In addition, an electric field is generated between the stator and rotor. The presence of the plastic shell helps to maintain the stability of the electric field and avoid electric field distortion.
[0019] This invention relates to a dishwasher water pump with a cleaning effect. The impeller assembly is equipped with cleaning brushes that can reach all corners and surfaces inside the water chamber, including complex structural areas and pipe connections. For stubborn stains, the brushes can remove them through physical friction. Compared to simple water rinsing, the brush bristles directly contact the stains, applying friction, which more effectively breaks down and removes the stains. Attached Figure Description

[0041] Preferred options are shown in the appendix. Figure 7 The rotating sleeve 29 is fixedly installed with a rotating blade 27 on its outer side. When the rotating blade 27 rotates, it disturbs the interior of the first cavity 23.
[0042] Preferred options are shown in the appendix. Figure 5 The stator assembly 11 includes a plastic housing 18, and the plastic housing 18 has a cavity inside, and a stator core 19 is fixedly installed inside the cavity.
[0043] Preferred options are shown in the appendix.

[0044] Preferred options are shown in the appendix. Figure 3 and appendix Figure 5 The upper part of the rotor assembly 12 is fixedly equipped with a rotating blade 17. The rotating blade 17 is installed through the first cavity 23 and placed inside the impeller assembly 24.

[0045] Preferably, referring to Figure 5, the plastic housing 18 fully encloses and seals the stator core 19, and the plastic housing 18 is made of BMC material or thermoplastic injection molding.
[0046] Preferably, referring to Figure 5, the plastic filler ring 34 is injection molded from BMC, PP, PBT and nylon materials.
[0047] Specific usage method of this utility model:
[0048] When using this equipment, first connect the inlet and outlet pipes to the outside. After the pipes are connected, connect the power supply to the equipment. After the connection is complete, water will enter through the inlet pipe 16 and then enter the first cavity 23 for pressurization and rotation. The water will then be discharged to the outside through the outlet pipe 14. However, after prolonged use, the stator and rotor will be in a humid environment, and moisture may seep into the windings of the stator and rotor, reducing the insulation resistance and increasing the possibility of leakage. However, this equipment is sealed by wrapping the rotor assembly 12 and stator assembly 11 with a shell made of thermosetting plastic material. This plastic seal can prevent moisture from entering the stator and rotor area. In humid environments, such as outdoor electrical equipment or equipment in factories near water sources (such as paper mills, printing and dyeing plants, etc.), moisture can easily penetrate unsealed motors and other equipment, causing a decrease in insulation resistance and thus leakage.
[0049] Subsequently, during operation, the first chamber 23 will develop scale due to prolonged direct contact with unpurified water. This scale buildup increases the water adsorption resistance of the impeller assembly 24 and may damage the stator assembly 11 or rotor assembly 12. As the impeller assembly 24 rotates, the impeller blades 33 and their rotating blades 17 rotate synchronously. The rotating blades 17 increase the pressure on the water inside the first chamber 23. Simultaneously, the impeller blades 33 increase the pressure synchronously. Furthermore, the outer side of the spiral cleaning plate 31 is equipped with bristles... The brush cleans the inner wall of the first cavity 23. The cleaned dirt will flow out through the water flow. After the spiral cleaning plate 31 removes the hard scale, the hard scale will rotate inside the first cavity 23. When the hard scale comes into contact with the spiral cleaning plate 31, it will undergo the first step of breaking. Then, the broken hard scale will be discharged to the outside through the drain pipe 25. When the rotating blade 17 and the spiral cleaning plate 31 rotate around the water in the first cavity 23, they form a two-way spiral force, which increases the water flow pressure inside the first cavity 23. The high water flow pressure breaks down the dirt inside the first cavity 23. Finally, the broken dirt is discharged to the outside through the external drain pipe 14.
[0050] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art.
