Koyer is a professional supplier of washing machines in China. With over 30 years of experience, the company specializes in manufacturing DC washing machines, semi-automatic washing machines, single-tub washing machines and more. Its products are exported to over 30 countries, backed by robust technical support, excellent quality and service.
A DC washing machine incorporates a direct current motor, typically a brushless DC motor. It requires an internal converter to transform household alternating current into direct current for operation. This design offers advantages including low energy consumption, minimal noise, and precise speed adjustment to accommodate varying wash requirements.
1. Households or settings with DC power supply: Homes equipped with photovoltaic systems and battery storage can utilise compatible DC washing machines to eliminate energy conversion losses while directly utilising DC power. Additionally, scenarios such as motorhomes, yachts, and wilderness campsites often rely on 12V or 24V battery power. They can be easily connected to batteries via crocodile clips to fulfil laundry requirements.
2. Demands for quiet operation and delicate washing: For compact living spaces where the washing machine is adjacent to bedrooms, or households with infants, elderly residents, or those requiring gentle care, DC washing machines operate smoothly with minimal noise, allowing night-time washing without disturbance. Their precise speed control prevents damage to delicate fabrics like wool and silk, making them ideal for families frequently laundering high-end garments.
3. Pursuit of long-term energy efficiency and durability: DC motors achieve over 90% electrical conversion efficiency, delivering significant electricity savings over extended use. Their reduced reliance on transmission components like belts results in fewer faults and enhanced longevity, making them ideal for households prioritising stable, low-maintenance appliance operation.
4. Specialised low-voltage safety requirements: In environments with stringent electrical safety protocols—such as certain dormitories or small medical support facilities—low-voltage DC washing machines maximise personal safety by eliminating electrocution risks.
1.Choose lead-acid batteries if you have a limited budget and plan battery replacement within 1 to 2 years.
2.Choose lithium batteries for longer service life and lighter weight.
