Description

Technical Field

[0001] The utility model relates to a dishwasher accessory, in particular to a suspended shock-absorbing installation structure for a dishwasher water pump. Background Art

[0002] As modern household living standards improve, dishwashers have become a staple in kitchens. A key component of a dishwasher's operation is the water pump, responsible for pushing water for cleaning. The pump is typically connected to a motor and driven by it. However, over the long term, vibrations generated by the pump and motor can become a problem. This can cause internal loosening, increase noise levels, and even shorten the lifespan of a dishwasher, especially at high speeds or under heavy loads.

[0003] In existing technology, dishwasher water pumps and motors are often connected using a rigid connection. This connection lacks sufficient vibration dampening measures, causing vibrations to be directly transmitted to the dishwasher body, affecting the user experience and easily damaging other components. To address this vibration problem, some dishwashers use simple rubber pads as a buffer. However, due to structural design limitations, this type of vibration dampening method is limited in effectiveness and cannot effectively address the vibration issues caused by long-term use.

[0004] Furthermore, existing dishwasher water pumps often have complex mounting structures, resulting in high installation and maintenance costs. In particular, the installation of the water pump and motor requires multiple adjustments to ensure optimal operation. This not only increases production complexity but also increases the cost of equipment repair and component replacement.

[0005] In summary, the main defects of the existing technology include:

[0006] 1. The rigid connection between the existing dishwasher water pump and the motor or the simple rubber buffer design cannot effectively reduce the vibration generated during the operation of the water pump, causing the vibration to be directly transmitted to the dishwasher body, increasing noise and mechanical losses.

[0007] 2. The connection structure between the water pump and the motor is complex, and the installation and maintenance process is cumbersome, which increases production and maintenance costs.

[0008] 3. Since the vibration problem has not been effectively solved, long-term use may cause damage to other components inside the dishwasher, shortening the overall service life of the device. Therefore, further improvements are necessary. Utility Model Content

[0009] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a dishwasher water pump suspended shock-absorbing mounting structure with a simple structure, easy use, and the ability to effectively reduce the vibration generated by the water pump and motor during operation, reduce noise, extend the service life of the equipment, simplify the installation process, and reduce production and maintenance costs.

[0010] The purpose of the utility model is achieved in the following way: a suspended shock-absorbing mounting structure for a dishwasher water pump, comprising a motor and a pump body driven by the motor, the pump body being fixed to the output end of the motor; wherein the motor comprises a front housing and a rear housing, the stator being clamped and fixed between the front housing and the rear housing, the front housing extending outward to form a front bracket, the rear housing extending outward to form a rear bracket, one end of a shock-absorbing hanging ear being mounted between the front bracket and the rear bracket, and the other end being connected to the dishwasher body via a hanging ear, two sets of each of the front bracket, the rear bracket and the shock-absorbing hanging ear being provided, which are symmetrically distributed on both sides of the motor, so that the motor is suspended and mounted in the dishwasher through the above-mentioned two sets of mechanisms.

[0011] Furthermore: the shock-absorbing ear is made of rubber material, a connecting seat is provided at the bottom of the shock-absorbing ear, a mounting hole is provided horizontally in the connecting seat, and the fixing screw passes through the front bracket and the mounting hole and is connected to the rear bracket, so that the shock-absorbing ear is hingedly installed between the front bracket and the rear bracket.

[0012] Furthermore, a buckle hole is provided on the top of the shock-absorbing hanging ear, and a hook portion provided on the hanging ear extends into the buckle hole and is connected thereto.

[0013] Furthermore: the middle part of the shock-absorbing ear is hollowed out to form a shock-absorbing cavity.

[0014] Furthermore: the top of the hook hole is a cylindrical hook portion, and the hook portion provided on the hanging ear is hooked on the hook portion and connected with it.

[0015] Furthermore: the water inlet end of the pump body is connected to the main unit through a water inlet hose, and the water outlet end of the pump body is connected to the main unit through a drain hose.

[0016] The beneficial effects of the utility model are: 1. Simple structure, low production cost and improved market competitiveness.

The lugs are made of rubber and feature a central damping chamber, effectively absorbing and buffering vibrations generated by the water pump. Compared to existing rigid connection structures, this suspension-style installation significantly reduces vibration transmission to the dishwasher body, reducing operating noise and improving the user experience.

[0018] 3. The utility model features a simple, hanging installation structure. The hook connection between the lugs and the buckle holes allows for quick installation and removal of the motor and pump, reducing production and maintenance costs. The hanging installation reduces the need for multiple adjustments, facilitating easier alignment of the pump and motor during installation and ensuring stable operation, effectively improving installation efficiency.

[0019] 4. The vibration-absorbing lugs absorb and cushion vibrations, reducing their impact on other components within the dishwasher. This reduces the risk of loose parts or wear caused by vibration, extending the overall lifespan of the dishwasher. Furthermore, the durable rubber material and unique damping cavity design of the vibration-absorbing lugs maintain excellent shock absorption performance over time, contributing to improved durability.

[0025] The present invention is further described below in conjunction with the accompanying drawings. A suspended, shock-absorbing mounting structure for a dishwasher water pump includes a motor 1 and a pump body 2 driven thereby, the pump body 2 being fixed to the output end of the motor 1. The motor 1 includes a front housing 11 and a rear housing 12, with a stator 13 clamped and fixed between the front and rear housings 11, 12. The front housing 11 extends outward to form a front bracket 14, and the rear housing 12 extends outward to form a rear bracket 15. A shock-absorbing lug 3 is mounted at one end between the front and rear brackets 14, 15, and connected to the dishwasher body via a lug 4. Two sets of front brackets 14, rear brackets 15, and shock-absorbing lugs 3 are each provided, symmetrically distributed on either side of the motor 1, so that the motor 1 is suspended and mounted within the dishwasher via these two mechanisms.

[0026] In one embodiment: the shock-absorbing ear 3 is made of rubber material, a connecting seat 31 is provided at the bottom of the shock-absorbing ear 3, and a mounting hole 32 is horizontally provided in the connecting seat 31. After the fixing screw 5 passes through the front bracket 14 and the mounting hole 32, it is connected to the rear bracket 15, and the shock-absorbing ear 3 is hingedly installed between the front bracket 14 and the rear bracket 15.

[0027] In one embodiment, a buckle hole 33 is provided on the top of the shock-absorbing hanging ear 3 , and a hook portion 41 provided on the hanging ear 4 extends into the buckle hole 33 and is connected thereto.

[0028] In one embodiment, the middle portion of the shock-absorbing ear 3 is hollowed out to form a shock-absorbing cavity 35 .

[0029] In one embodiment, the top of the hook hole 33 is a cylindrical hook portion 34 , and the hook portion 41 provided on the hook ear 4 is hooked on the hook portion 34 and connected thereto.

[0030] In one embodiment, the water inlet end of the pump body 2 is connected to the main unit through a water inlet hose, and the water outlet end of the pump body is connected to the main unit through a drain hose.

[0031] Working Principle: When the dishwasher is running, motor 1 drives pump 2. The motor's output is directly connected to the pump, which, through the impeller within the pump chamber, circulates water, achieving the dishwasher's cleaning function. Because the motor and pump generate significant vibration and noise during operation, this utility model utilizes rubber vibration-damping lugs 3 to suspend the motor within the dishwasher. The elasticity of the vibration-damping lugs and the central vibration-damping cavity 42 effectively absorb vibration generated by the motor and pump, significantly reducing the amount of vibration transmitted to the dishwasher's main body, thereby reducing noise and mechanical impact on the equipment.

[0032] The motor's front housing 11 and rear housing 12 are connected to the vibration-damping lugs 3 via front brackets 14 and rear brackets 15, respectively. These lugs are hinged to the brackets via transverse mounting holes 32 and set screws 5, allowing the motor to be suspended within the dishwasher. This suspended design avoids vibration transmission associated with a rigid connection, particularly since vibrations from the motor and pump body are effectively dampened by the elastic properties of the rubber lugs. This suspended mounting also allows the motor to have a certain range of motion during operation, further mitigating the impact of vibration on the system.

[0033] The motor is secured via two symmetrically arranged front and rear brackets 14 and 15, along with shock-absorbing lugs 3. This bilaterally symmetrical design ensures even force distribution on the motor during operation, reducing vibration and wear caused by eccentricity. This uniformly distributed suspension not only improves the smooth operation of the motor and pump, but also effectively extends the service life of the equipment.

[0034] Furthermore, the top of the shock-absorbing lug 3 is provided with a hook hole 33, which is connected to the hook portion 41 on the lug 4 to suspend the motor within the dishwasher. The lug design simplifies installation, eliminating the need for complex adjustments and calibration, allowing the motor and pump to be stably suspended within the dishwasher. This connection method not only enhances installation convenience but also facilitates subsequent maintenance and repair.

[0035] Compared with traditional technology, the suspended shock-absorbing mounting structure in this case effectively absorbs the vibration of the motor and pump body through the rubber shock-absorbing ears and shock-absorbing cavity 42, avoiding the phenomenon of vibration in the rigid connection being directly transmitted to the dishwasher body, greatly reducing the noise during the operation of the dishwasher, and improving the user experience.

[0036] The mounting structure of this utility model is simple in design. By hooking the hanging lug 4 and the shock-absorbing hanging lug 3, the motor and pump body can be quickly installed in place, simplifying the installation process. At the same time, the hook connection method facilitates subsequent inspection and maintenance, reducing production and maintenance costs and improving the overall reliability of the equipment.

[0037] By absorbing vibrations from the motor and pump, the vibration-damping lugs reduce their impact on other components within the dishwasher, minimizing mechanical shock and wear. This not only improves overall operational stability but also effectively extends the dishwasher's lifespan, maintaining excellent vibration damping even under extended use or high loads.

[0038] Furthermore, the front bracket 14, rear bracket 15, and shock-absorbing lugs 3 of the present invention are symmetrically distributed on either side of the motor, ensuring even force distribution during operation. This symmetrical structural design effectively avoids vibration and imbalance caused by eccentric force on the motor or pump during operation, ensuring smooth operation of the dishwasher and further reducing mechanical losses.

[0039] Furthermore, the suspended mounting structure allows the motor to move freely within a certain range, avoiding the vibration transmission issues associated with rigid fixed structures. The elastic properties of the mounting lugs ensure that the motor and pump remain stable during operation even when subject to external disturbances, such as the movement of the dishwasher or the impact of internal water flow, thereby enhancing the overall vibration resistance of the dishwasher system.

[0040] This new suspended, shock-absorbing mounting structure for dishwasher water pumps effectively addresses the vibration transmission issues encountered in existing technologies through a rational suspension design, simplifying installation and maintenance. Thanks to its efficient shock absorption, symmetrical load-bearing design, and flexible suspension connection, this structure significantly reduces operating noise and extends the life of the equipment, making it suitable for widespread adoption.

[0041] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements shall fall within the scope of the present invention as claimed.
