A household dishwasher typically requires several modules to support fully automatic operation: a washing module, a drying system, a drainage module, and auxiliary modules. Micro motors play a significant role in this. Specific motor types and functions are as follows:

I. Washing Module Motors

1. Main Washing Motor (DC Brushless Motor)

Location: Bottom, connected to the spray arm system

Function: Drives the spray arms to rotate, generating high-pressure water to rinse dishes. Supports frequency conversion adjustment to adapt to washing intensity requirements.

2. Water Pump Motor (Micro Gear Motor or Brushless Motor)

Location: Inlet water pipe or circulating water circuit

Function: Pressurizes and circulates water to ensure effective high-pressure rinsing.

II. Drying System Motors

1. Hot Air Fan Motor (DC Brushless Motor)

Location: Top or rear air duct

Function: Drives the fan to circulate hot air, accelerating the drying process.

III. Drainage Module Motors

1. Drain Pump Motor (Miniature DC Motor or Miniature Gear Motor)
Location: Bottom drain pipe
Function: Drains washing wastewater and residue; some models support a forced-drain mode to handle oily wastewater.

IV. Auxiliary Function Motors

1. Dish Basket Lifting Motor (Miniature Gear Motor)

Location: Inside the dish basket support
Function: Adjusts the height of the dish basket to accommodate different tableware sizes.

2. Smart Door Control Motor (Gear Motor)

Location: Door hinge

Function: Controls the automatic opening and closing of the door, enabling steam release during the drying stage.

3. Disinfection Module Motor (Miniature DC Motor)

Location: Near the UV lamp arm or plasma generator

Function: Drives the disinfection components to move, enhancing sterilization coverage. For a smart dishwasher, the types of miniature motors used include brushed DC motors, brushless motors, and geared motors.
