Description

Technical Field

[0001] This utility model relates to the field of washing pump technology, and in particular to a heated washing pump. Background Technology

[0002] As a core component of modern cleaning equipment (such as dishwashers), the wash pump's function is not limited to liquid circulation and transportation; it often needs to heat the fluid to improve cleaning effectiveness. Traditional heated wash pumps typically use external heating devices or built-in electric heating elements to raise the fluid temperature. However, existing technologies still have many limitations in practical applications.

[0003] First, regarding heating efficiency, traditional designs often separate the heating element from the fluid path or employ simple contact heating structures, resulting in low heat transfer efficiency. For example, external heating devices are prone to increased energy consumption due to heat loss, while if the layout of the internal heating element fails to achieve sufficient contact with the fluid, it is difficult to achieve rapid and uniform heating. Second, energy consumption is a significant issue. Some existing pumps require prolonged operation to maintain temperature due to low heating efficiency, which not only increases electricity costs but may also accelerate component aging. Furthermore, structural complexity is a prominent problem. Some heated washing pumps employ multi-layered piping or redundant insulation designs to improve heat transfer efficiency, resulting in a bulky internal structure. This not only increases manufacturing costs but also makes maintenance more difficult, especially when disassembling and replacing heating elements, which is cumbersome.

[0004] In terms of reliability, the design of existing technologies where the heating element is in direct contact with the fluid may lead to electrolytic corrosion or scale buildup, which can easily cause component damage or a decline in heat transfer performance over long-term use. Meanwhile, insufficient heat resistance of the pump body material at high temperatures may cause deformation or seal failure, shortening the equipment's lifespan. Furthermore, insufficient temperature control precision is also a major pain point; some products rely on simple temperature control switches, making precise temperature adjustment difficult, potentially affecting the consistency of washing results and even leading to overheating risks.

[0023] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] In the description of this utility model, the use of "first" and "second" is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features or the order of the technical features.

[0025] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0026] Reference Figures 1 to 7 This utility model discloses a heated washing pump, including a motor unit 10, a pump body 20, and a heating unit 30. The motor unit 10 provides power to drive the liquid. The pump body 20 is connected to the motor unit 10 and drives the liquid. The heating unit 30 is disposed on the pump body 20. The heating unit 30 includes a heating tube groove 31 and a heating tube 32. The heating tube 32 is embedded in the heating tube groove 31. Part of the heating tube 32 is disposed in the pump body 20. Another part of the heating tube 32 is located in the pump body 20 and is in close contact with the pump body 20. The heating tube 32 is used to heat the liquid in the pump body 20.

[0027] The heating tube 32 achieves efficient heating through a dual-path heat conduction design. First, the tube section embedded in the pump body 20 is in direct contact with the pump body material, such as aluminum alloy, through the heating tube groove 31, utilizing the metal's thermal conductivity to rapidly transfer heat. Second, the tube section exposed in the pump cavity 24 is in direct contact with the flowing liquid through its surface, achieving convective heat transfer. This dual heat transfer mode significantly improves thermal efficiency compared to traditional single heating methods and avoids the increased liquid flow resistance problem caused by a fully embedded design.

[0028] Reference Figures 1 to 7 The pump body 20 includes a pump housing 21, a motor end sealing cover 22, a water inlet end cover 23, and a pump chamber 24. The pump housing 21 is fitted onto the motor part 10. The motor end sealing cover 22 is located at one end of the pump housing 21 near the motor part 10. The water inlet end cover 23 is located at one end of the pump housing 21 and is opposite to the motor end sealing cover 22. The pump housing 21, the motor end sealing cover 22, and the water inlet end cover 23 form the pump chamber 24. A water inlet pipe 231 is connected to the water inlet end cover 23. A heating part 30 is provided on the water inlet end cover 23.

[0029] By placing the heating element 30 on the water inlet end cap 23, the heating element 30 can heat the incoming water immediately, thereby improving heating efficiency.

[0030] Reference Figures 1 to 7 The heating tube groove 31 is opened on the water inlet end cover 23 and is arranged around the water inlet pipe 231.

[0031] The annularly distributed heating tube grooves 31 make the heating tubes 32 form an annular heat source, creating a uniform thermal field around the inlet pipe 231. When the liquid enters the pump chamber 24 from the inlet pipe 231, it first passes through the annular heating area of ​​the heating tubes 32, achieving inlet preheating.

[0032] Reference Figures 1 to 7 The heating tube groove 31 has a semi-circular cross-section, and the groove wall of the heating tube groove 31 protrudes away from the pump housing 21. Half of the heating tube 32 is embedded in the heating tube groove 31, and the other half is located in the pump chamber 24 and is in direct contact with the liquid in the pump chamber 24.

[0033] The liquid is heated directly in the pump chamber 24 by one half of the heating tube 32, and the other half is heated over a wide area by heat conduction through the water inlet end cap 23. The dual approach greatly improves the heating efficiency, while only half of the heating tube 32 is located in the pump chamber 24, so it will not affect the water flow in the pump chamber 24.

[0034] Reference Figures 1 to 7 The heating tube groove 31 has openings 311 at both ends. The heating tube 32 passes through the openings 311 to achieve electrical connection with the outside.

[0035] It is worth noting that in some embodiments of this utility model, a temperature control component is provided on the outside of the pump body 20. When the temperature is too high or the pump chamber 24 is dry-burning due to lack of water, the temperature control component disconnects the power supply to protect the system. A water temperature sensor is also integrated inside the heating tube 32. When the water temperature sensor detects that the water temperature is lower than the system-set temperature, the heating tube 32 operates; when the water temperature reaches the system-set temperature, the heating tube 32 stops heating. This significantly reduces safety hazards and improves the product's safety factor.

[0036] Reference Figure 4 The heating washing pump of this utility model also includes a heat protection plate 40. The heat protection plate 40 is disposed on the pump housing 21. Part of the heating pipe 32 is located between the heat protection plate 40 and the water inlet end cap 23.

[0037] It is worth noting that the heat shield 40 can further prevent excessive heat radiation to the outside.

[0038] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0039] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
