Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of dish-washing machine accessories, specifically a pump shell can be quickly disassembled dish-washing machine circulating water pump. BACKGROUND

[0002] As indispensable cleaning equipment in modern family and catering industry, dish-washing machine has the advantages of liberating labor and improving cleaning efficiency. One of the key components of dish-washing machine is circulating water pump, which is responsible for circulating water through the spray system to achieve the purpose of efficiently cleaning tableware. In the prior art, dish-washing machine circulating water pump is usually composed of pump body and pump shell. The pump body includes driving motor and impeller, and the pump shell is mainly used to protect the impeller and form a closed water circulation structure.

[0003] The existing dish-washing machine circulating water pump usually adopts multiple connecting bolts to tightly connect the pump shell and the pump body. This traditional connection method has some significant defects, which are as follows: 1. In the production and assembly process, the connection of the pump shell and the pump body requires sequentially tightening multiple connecting bolts. Generally, the number of connecting bolts is usually four or more, and the operator on the assembly line needs to tighten these bolts one by one, which makes the entire assembly process more tedious and inefficient.

[0004] 2. Due to the complex structure of circulating water pump, it is necessary to ensure the consistency of the torque of each bolt to ensure the sealing when tightening multiple bolts, which increases the difficulty and workload of assembly, resulting in high production cost and easy to produce errors in the assembly process.

[0005] 3. After using dish-washing machine for a period of time, the water flow inside the circulating water pump often contains oil stains, residues and other impurities, which will cause fouling and blockage inside the pump body. In order to maintain the normal working efficiency of dish-washing machine, the user needs to disassemble and clean the water pump regularly. The existing water pump structure needs to sequentially disassemble multiple connecting bolts, which not only consumes time, but also requires additional tool support. When re-connecting the pump shell and the pump body, it is also necessary to fix each bolt one by one, which increases the difficulty and time cost of maintenance, and the user experience is not good. The traditional multi-bolt connection method requires certain operation skills from the user, which not only requires relatively more tools, but also can easily cause sealing problems when installed improperly, further causing water pump leakage or abnormal work, affecting the overall service life and reliability of dish-washing machine.

[0006] 4. The multi-bolt connection method places high demands on the seal between the pump body and the pump casing. Since each bolt must be tightened to a consistent torque, insufficient or excessive tightening force in any bolt can cause misalignment in the gap between the pump casing and the pump body, thus affecting the overall sealing performance. This can easily lead to liquid leakage inside the pump, thereby affecting the dishwasher's cleaning effect and the long-term stability of the water pump. Therefore, further improvements are necessary. Utility Model Content

[0037] Working principle: in this case, the driving motor 2 through its main shaft passes through the pump body 1 and impeller 3 connection. When the driving motor is powered on, its main shaft drives the impeller to rotate, the rotation of the impeller generates centrifugal force, pushes the water inside the pump shell 4 to the water outlet 42 direction, forms a circulating water flow. This design makes full use of the working principle of centrifugal pump, through the rotation of the impeller produces strong water flow pressure, the water in the dishwasher is quickly circulated, so as to achieve high efficiency washing effect.

[0038] In which, the pump shell 4 embedded with heating pipe 5, heating pipe terminal through the pump body 1 and connected with external power supply. When the dishwasher works, the heating pipe can heat the water circulating in the pump, improve the temperature of water, so as to enhance the washing effect. The heated water under the impeller into the dishwasher circulation system, so that the water temperature is always kept in the temperature interval suitable for washing tableware, effectively dissolve grease and stubborn stains, improve the cleaning ability and efficiency of dishwasher.

[0039] It needs to be explained that: the connection between pump body 1 and pump shell 4 through the coaxial connection of butt joint table 11 and butt joint hole 43. The butt joint table 11 set on the pump body is inserted into the butt joint hole 43 on the pump shell during installation, which ensures the coaxial alignment of the pump body and the pump shell, thereby providing stable mechanical connection.

[0040] The connection between the pump body and the pump shell is further completed by the rotation of the groove 12 and the card table 44. The card table 44 enters the rotation groove 12 along the guide slope 45, and is stably locked into the rotation groove through the rotation of the card table. This design not only simplifies the installation process, but also provides reliable mechanical connection.

[0041] In the connection process, the sealing ring 7 is installed in the concave sealing groove 15 on the pump body butt joint surface, and the sealing table 46 on the pump shell cooperates with the sealing groove 15 to clamp the sealing ring between them, forming a good sealing structure. In this way, under the pressure generated by the high-speed rotation of the impeller, the connections of the water pump can maintain good sealing state, effectively preventing water leakage.

[0042] In which, since the butt joint between the pump body and the pump shell adopts the combination of butt joint table and card table, it does not need to tighten multiple bolts, realizes quick connection and disassembly, greatly reduces the time and labor in the process of assembly and maintenance. The clamping design between the sealing ring and the sealing groove and the sealing table ensures the reliable sealing between the pump body and the pump shell, solves the problem of poor sealing caused by uneven torque in traditional multi bolt connection, and improves the sealing performance of the whole water pump.

[0043] The pump body 1 is further provided with a locking screw hole 13, and the pump shell 4 is provided with a corresponding locking bolt 6, which is inserted into the grounding sheet 9 and is screwed with the locking screw hole 13. After the pump body and the pump shell are connected and clamped, the fixation of the locking bolt can further ensure that the pump shell and the pump body cannot move relatively, thereby ensuring the long-term stable operation of the water pump in a high-pressure and high-temperature environment. The design of the locking mechanism further enhances the connection firmness between the pump body and the pump shell, and the integration of the grounding sheet increases the electrical safety of the system, especially in the case of a heating pipe in the pump shell, which ensures the safe use of the overall equipment.

[0044] Further, the pump body 1 is further provided with a guide plate 8 corresponding to the water outlet 42 of the pump shell. The guide plate is inclinedly arranged towards the water outlet, and when the impeller pushes water towards the water outlet, the guide plate can help the water flow smoothly into the water outlet direction, reducing the flow resistance. The guide plate not only optimizes the water flow path, but also reduces the energy loss caused by turbulent water flow, so that the working efficiency of the water pump is further improved. The setting of the guide plate optimizes the water flow path and reduces the energy loss of the water flow, ensuring that the dishwasher can obtain more stable and efficient water flow during the washing process, improving the working efficiency and washing effect of the pump.

[0045] In summary, the utility model discloses a clever structure design, the connection between the pump body and the pump shell is more convenient and fast, greatly improves the efficiency of assembly and maintenance, and through multiple sealing and stable locking design, the stability and sealing property of the water pump are ensured. In addition, the integration of the heating pipe and the guide plate makes the dishwasher not only have higher washing efficiency during use, but also greatly improves the user's use experience and the overall reliability of the product, so it can be widely used.
