Home appliances

For example, recently, the following items are increasing as appliances are being used, along with the evolution of home appliances.

• DC motor or battery-driven fan
• Air cleaner
• Battery-powered vacuum cleaner
• Robot vacuum cleaner
• humidifier
• Deodorizing machine
• Small refrigerator
• Facial Equipment etc.

On the other hand, in the consumer electronics industry, along with the globalization of products, in the overseas development of products, “what are the necessary regulations such as safety standards and energy saving regulations for equipment and AC adapters?" and opportunities to see customers of your troubles have increased. Although the safety assessment of the product itself is specific, it is natural that customers will be troubled because the technical standards and legal systems that must be protected are different depending on the country to which the home appliance is directed. At UNIFIVE, we make products closely related to customers' worries.

Example of development of an AC adapter used for electric fans for the European market

The production site used China's EMS, which was bundled with the fan and planned to be sent to Europe. We first checked what policy we would obtain regarding the customer's power supply requirements and compliance with safety and technical standards.

As a result of confirmation, the primary problem was acquiring safety standards. Obtaining EN 60335 was indispensable for the application of this equipment. However, IEC / EN 60335 is a certification body. Although some opinions differ, it cannot be acquired separately from the AC adapter. It is the safest means for customers to request an evaluation from a set of AC adapters and equipment with a certification body.

Also, when evaluating the set of EN 60335, it was necessary to submit a CB indicating that even an AC adapter separately meets EN 61558. IEC / EN 61558 structural requirements requested the transformer used with the equipment. Since our company uses a transformer for the AC adapter itself, from the viewpoint of product warranty, the AC adapter acquired IEC / EN 61558, and a CE declaration was made. 

Even after being placed on the customer, we received the SET evaluation of EN 60335, finished development safely, and delivered the AC adapter of your choice.

In this case, the design of the AC adapter was able to acquire 61558, and the AC adapter was designed. Standards were acquired in anticipation of satisfying the structural requirements of IEC 60335. If we make a mistake in initial confirmation, we may delay the acquisition of standards, but we could first exchange information closely with customers so the development is completed.

In countries not members of the IEC, we do more complicated things than this. Our company has abundant experience in various other domestic appliances for other countries.
