The invention discloses a washing machine with ozone heater (1 ) provided with a heating box (3) , an electric heater (4) , a heating box cover (5) , a rubber seal (6) , a locking bolt (7) , an electric heater socket (8 ) and an electric cable (9) The washing machine with ozone heater (1) according to the invention is a modification of an existing washing machine or is specially manufactured. The washing process utilizes ozone water. At step 6, extract, the electric heater (4) operates to heat up the air within the outer tube (2) and inner tube (10). Heat from the electric heater (4) will heat up the inner tube (10) and outer tube (2). With the heat from the electric heater (4), ozone will be easily decomposed entirely to oxygen. Therefore, when the washing machine (1) is open at the final step of the washing process, the operator will be safe from the possibility of ozone exposure.
