Abstract:
1. A combustion fan installation structure of a gas radiation oven range comprising: a top burner unit having an opened upper side and having a burner assembly coupled therein; an outer case including a grill unit coupled at a lower side of a top case and an oven unit coupled at a lower side of the grill unit; a ceramic glass coupled at the upper side of the top burner unit; a burner housing located at a top portion of the outer case and coupled to be in contact with the lower surface of the ceramic glass and forming an exhaust passage together with the lower surface of the ceramic glass; a cooling convey duct formed at a rear wall of the outer case to allow gases to flow therethrough, the cooling convey duct extending from a bottom end of the outer case up to and extending above a top surface of the ceramic glass, and the cooling convey duct having gas flow connectivity with the oven unit, with the grill unit, and with the exhaust passage below the ceramic glass; a radiant burner coupled at one side of the burner housing and generating radiant heat; a mixing pipe of which one end is coupled at one side of the radiant burner and the other end extends downwardly to be below the grill unit; a gas supply pipe coupled at one side of the mixing pipe; and a combustion fan located at a bottom portion of the outer case at a side wall thereof and coupled to the other end of the mixing pipe, wherein a separation plate is additionally installed at the space formed at one side of the oven unit constituting the outer case to section the space and the combustion fan, and wherein the entire combustion fan is located below the one end of the mixing pipe, and the one end of the mixing pipe is higher than the other end of the mixing pipe, and wherein the combustion fan operates to induce air to flow into an intake vent formed at a bottom surface of the outer case, pass through the mixing pipe, in which air and gas are combined to form a mixed gas, and the mixed gas being provided to the radiant burner of the burner housing in which combustion of the mixed gas occurs, and whereby exhaust gases as a result of the combustion pass through the exhaust passage, and exit via the cooling convey duct.
