Dishwasher as a modern kitchen clean revolution, not only the liberation of the hands, but also with the precision of the drainage mechanism to redefine the clean standard. It is not only the evolution of tools, but also the concrete expression of human's pursuit of life efficiency and health. Today, we'll explore the mysteries of dishwasher drainage and how technology is remaking our daily lives in a silent way.

(1)、Structure and working principle of drainage pump

1. structure

Drainage pump usually by the cover pole motor, impeller, sealing parts and pump body composition. The motor drives the impeller to rotate at high speed, and the impeller and the pump body form a sealing chamber. The pump body is equipped with a water inlet and a water outlet. Some models are also equipped with a one-way valve or a reverse flow prevention structure to prevent sewage backflow. The utility model is arranged at the bottom of the dishwasher beside the water collecting sink, and is connected with the drainage system through a pipeline.

2. how it works

When the washing process is finished, the motor starts to drive the impeller to rotate at a high speed, and the sewage is sucked into the pump body from the collecting tank by centrifugal force, and is discharged from the drain outlet to the sewer after the impeller is pressurized. Centrifugal design makes its high drainage efficiency, compact structure, can quickly drain clean sewage, avoid residual breeding bacteria.

(2)、Layout of drainage pipeline

The sewage pumped out by the drainage pump must pass through a carefully designed piping system to be discharged smoothly. The layout of this clean passage is very important, it not only affects the drainage efficiency, more directly related to the sanitary condition of the kitchen.

1. s-bend design of drainage pipe

The S-bend design of The Dishwasher drainpipe is ingenious. The bending structure can effectively retain a certain amount of water to form a water seal. The water seal acts as a natural barrier to prevent foul odors from flowing back into the dishwasher and contaminating the dishes. At the same time, reasonable radian design to ensure smooth drainage, will not impede the flow of water due to excessive bending, guarantee the normal drainage dishwasher.

2. moderate pipe diameter

It is very important to design the drainage pipe of dishwasher with moderate diameter. If the pipe diameter is too small, the water flow will be blocked during drainage, which is easy to cause poor drainage and lead to water accumulation in the dishwasher, affecting the washing effect and machine life. If the pipe diameter is too large, it will not only take up space, but also slow down the water flow speed, dirt deposits easily. Moderate pipe diameter can give consideration to both drainage efficiency and space utilization to ensure drainage stability.

(3)、Filtration system

Prior to drainage, sewage needs to pass through a strict filtration barrier to prevent large residue blocking the drainage pump or pipeline. The filter system of dishwasher is usually divided into coarse filter and micro-filter two layers.

1. coarse filter

The coarse filter is the first line of defense of the dishwasher filtration system, which is usually designed with a large aperture to intercept the large food residues such as leaves and bone chips off the tableware. Its grid structure allows water to pass through, and effectively blocks large particles from entering the subsequent filtration link, avoiding clogging the drainage system or damaging the pump, which provides a basic guarantee for subsequent fine filtration.

2. microfilters

The microfilter has a precise pore size of 0.1-10 microns to achieve deep purification, which can intercept impurities such as detergent residues, tiny food particles and bacteria. Its material is mostly ceramic or polymer, with corrosion resistance, high temperature resistance characteristics.

(4)、Drainage controlled by intelligent program

Dishwasher drainage is not a simple row away, but by the intelligent control system precision control.

1. stage drainage

Modern dishwashers are often equipped with multi-stage drainage procedures: brief drainage during the prewashing stage, replacing the clean water; thorough drainage after the main wash, in preparation for the rinse stage; drainage again after the rinse stage, after the rinse stage, make sure the cutlery is completely clean.

2. delayed drainage

Some models also support delayed drainage function, for stubborn stains, can be suspended after washing drainage, let detergent fully dissolve residue, improve the cleaning effect.

3. intensive drainage mode

In addition, the strong drainage mode can be manually activated when needed, quickly emptying the machine internal water, ready for the next washing, so that the dishwasher drainage more efficient and flexible.

Conclusion

Dishwasher drainage mechanism, is the perfect combination of mechanical design, materials science and intelligent control. From the precise operation of the drainage pump to the scientific layout of the pipeline, from the dual protection of the filtering system to the precise regulation of the intelligent control, each link embodies the wisdom and ingenuity of the engineer. It not only makes kitchen cleaning easy and efficient, but also silently guards our health and quality of life.
