Abstract
A washing machine has a container for containing detergent to be supplied into a washing tub and a device for applying a magnetic field to water to be supplied into the detergent container. The device includes a permanent magnet and a magnet casing for accommodating the permanent magnet. A passage part is formed on a central portion of the magnet casing, through which the water to be supplied into the detergent container passes. The magnet takes the shape of a ring surrounding the passage part. When water is supplied into the device, the magnetic field is applied to the water while the water is passing through the passage part, whereby metallic impurities such as calcium ion or magnesium ion are eliminated. The magnetized water is supplied into the detergent container, and thereby the detergent is effectively dissolved by the water.
