Electrolyzed water generator and water treatment device including same

An electrolyzed water generator comprising:

• an electrolysis chamber having an internal space;
• a separation membrane that divides the internal space of the electrolysis chamber into a first electrolytic compartment, a second electrolytic compartment, and a salt water tank between the first and second electrolytic compartments, and selectively permeates ionic substances;
• a first electrode disposed in the first electrolytic compartment;
• and
• a second electrode disposed in the second electrolytic compartment and having a polarity opposite to that of the first electrode,
• wherein at least one of the first electrode and the second electrode includes
• a substrate metal layer, and
• a catalyst metal layer having a thickness thinner than that of the substrate metal layer.

A water treatment device comprising:

• a soft water generator that receives raw water and generates soft water;
• a salt water generator that generates salt water;
• and
• an electrolyzed water generator that generates electrolyzed water by electrolyzing mixed water in which the soft water generated from the soft water generator and the salt water generated from the salt water generator are mixed,
• wherein the electrolyzed water generator includes
• an electrolysis chamber having an internal space,
• a diaphragm dividing the internal space of the electrolysis chamber into a first electrolytic compartment and a second electrolytic compartment,
• a first electrode disposed in the first electrolytic compartment, and
• a second electrode disposed in the second electrolytic compartment and having a polarity opposite to that of the first electrode, and
• at least one of the first electrode and the second electrode includes
• a substrate metal layer, and
• a catalyst metal layer having a thickness thinner than that of the substrate metal layer.
