What is a smart dishwasher?

There is a shallow basin at the bottom of the dishwasher. After starting the dishwasher and selecting a cleaning program, the water intake pump at the water source regulates the water and pours it into the dishwasher. At the same time, the sensor turns on the intake pump and draws the water into the dishwasher
The dishwasher is cleaned with hot water, and the water temperature range of the general dishwasher is 40°C-70°C, which can fully sterilize and sterilize. After the cold water is sucked into the dishwasher, the heating element at the bottom of the electric heat, gradually heating the water.
At the same time, an electric pump draws warm water and presses it into pipes on the side of the machine, which are connected to the spray arm.
Spray arms are free-swinging paddles with small holes, and the number, size and position of spray arms vary from brand to brand, and even from model to model, generally two up and down, which can cover the largest cleaning area.
When hot water enters the spray arm, it will rotate 360 degrees because of the reaction force. As it spins, hot water flows out of the tiny holes in it, creating a massive stream of hot spinning water that shoots up onto the dirty dish
The spray arm at the bottom is closer to the heating element, so the water in the lower part of the dishwasher is much hotter. When the spattered water hits the utensils and dishes, it falls to the bottom of the dishwasher, where it is heated again by the element and pumped through another cycle until the utensils are rinsed.

What's the feature of ceramic strontium ferrite magnet made by wet compression molding?

• Composition - Contain strontium ferrite (SrFe12O19) as the primary magnetic material. Strontium ferrite has good magnetic properties and is inexpensive to produce.

• Density - Have a high relative density of around 95% or more after sintering. This gives good mechanical strength.

• An-isotropy - Exhibit strong magnetocrystalline an-isotropy due to their hexagonal crystal structure. This results in a preferred direction of magnetization along one axis.

• Particle shape - The strontium ferrite powder used typically has a hexagonal platelet morphology which helps promote magnetic an-isotropy during molding and sintering.

• Molding method - The powder is mixed with a liquid binder and compression molded into a dense green compact using high pressures. This orients the an-isotropic particles.

• Firing process - The compact is then sintered at high temperature to develop density while preserving the induced magnetic anisotropy orientation from molding.

• Remanence - Have a maximum magnetic flux density or remanence along the axis of anisotropy, but little/no remanence perpendicular to it.

• Coercivity - Usually have medium to high coercivity depending on additives, density, and anisotropy level achieved.

What's the key advantages of ceramic strontium ferrite magnets made by wet compression molding?

• Low cost - Strontium ferrite is inexpensive and the wet molding process is relatively simple. This makes them cheaper than rare-earth magnets.

• High magnetic property-Even without heavy rare earth element additions, strontium ferrite magnets can achieve coercivities of 700-1000 kA/m, making them suitable for many applications.

• Dimensional consistency - The compression molding process allows for close dimensional tolerances and uniform magnet shapes to be produced consistently.

• Temperature stability - Strontium ferrite magnets have high Curie temperatures, typically around 450-470°C. They maintain good magnetic properties over a wide operating temperature range.

• Resistance to corrosion - Being fully dense ceramic materials, they are not prone to corrosion like bonded magnets containing additives.

• Mass production capability - The molding process is amenable to automated high-volume manufacturing of complex magnet geometries.​​

Introduction Of Inverter Motor:

An inverter motor, also known as a variable frequency drive (VFD) motor, operates based on the principles of variable frequency control and motor speed regulation. It is commonly used in various applications where precise speed control and energy efficiency are required.

Variable Frequency Control: An inverter motor operates by adjusting the frequency of the electrical power supplied to the motor. Unlike traditional motors that operate at a fixed frequency, inverter motors allow for flexible and adjustable frequency control. By varying the frequency, the motor's rotational speed can be precisely regulated.

Power Conversion: Inverter motors utilize power electronics and control circuits to convert the incoming AC power into DC power. The DC power is then inverted back into AC power at the desired frequency and voltage levels. This conversion process allows for the generation of variable-frequency power that drives the motor.
