NOVELTY - An apparatus for producing a mixture of hydrogen and oxygen, comprises an outer plate member unit (10) in which first plate members having a main hole in its center and a circular gasket having a certain thickness and surrounding the main hole are alternately installed.    USE - The apparatus is used for producing a mixture of hydrogen and oxygen (claimed).    ADVANTAGE - An apparatus for more efficiently producing a mixture of hydrogen and oxygen using water is provided. The surfaces of the first and second plate members are nano-polished so electrolysis can efficiently occur, and the produced hydrogen and oxygen bubbles can be easily detached. The apparatus can promote an economic production by increasing the amount of a mixture of hydrogen and oxygen as compared to electric energy used. It is possible to more efficiently produce a mixture of hydrogen and oxygen without adding an auxiliary gas such as propane by increasing the amount of hydrogen and oxygen as compared to electric energy used, which leads to more economical production. Since the hydrogen and oxygen produced in bubble shapes from the electrodes can be easily separated, the effective area of the electrodes in which electrolysis occurs is increased, by means of which an electrolyte efficiency can be enhanced.    DETAILED DESCRIPTION - An apparatus for producing a mixture of hydrogen and oxygen, comprises an outer plate member unit (10) in which first plate members having a main hole in its center and a circular gasket having a certain thickness and surrounding the main hole are alternately installed; front and rear covers (30, 40) which are installed in the front and rear sides of the outer plate member unit (10) and fixes the inner plate member unit spaced apart from an inner side of the main hole and is insulated from the inner plate member unit; a water supply hole (50) which is formed in the front cover (30) for supplying water to the electrolyte space; and a gas discharge hole (50) which is formed in the front cover (30) for discharging a mixture of hydrogen and oxygen. The first plate member form a body, and the main holes of the first plate member form a cylinder, and the inner side of the circular gaskets and the main holes (11 a) form an electrolyte space in which electrolysis occurs, and in the electrolysis space, the outer sides of the circular gaskets play a function of the cooling fins.
