  However, in the conventional configuration, the structure is complicated, and expensive parts are used, and control parts such as electrodes are required, so that it is difficult to incorporate in a general washing machine. Therefore, it has a problem that it can be used only for a high-grade type washing machine.

  This invention solves the said conventional problem, and provides a washing machine which has an ion elution apparatus which can perform elution of silver ion stably and efficiently over a long period of time with an inexpensive structure.

  In order to solve the conventional problems, a silver ion elution device of a washing machine of the present invention includes a water tank for storing water of a washing machine, a water supply valve arranged in an upper frame body of the washing machine body and supplying water to the water tank, A water inlet that introduces washing water from the water supply valve into the water tank in the upper frame, and the water inlet is substantially box-shaped with a storage lid and a storage case provided with a shelf. In the shelf, a mesh-like storage bag enclosing a small piece of silver crystal material kneaded with silver ions is placed, and the washing water flowing in from the inlet connected to the water supply valve is placed on the shelf from below the shelf. It passes through the storage bag arrange | positioned in this, it flows out from the outflow port part set to the storage case part upper part, and it comprises so that it may supply to a water tank.

  As a result, washing water in which silver ions are eluted at the time of water supply is made, and the washing clothes in the water tank and the washing and dehydrating tank are made to have an antibacterial effect by the washing water containing silver ions. Since silver ions can be easily eluted in water, it can be incorporated into a washing machine at low cost.
