A valve cap of an electric pressure rice cooker for reducing steam discharging noise and steam discharging height is provided to install a second member sealing an upper surface of a first member while forming a crack at the upper and lower surfaces of a first member. A valve cap of an electric pressure rice cooker for reducing steam discharging noise and steam discharging height comprises a first member(10) and a second member(20). The first member is assembled to a steam discharging port and opened to the upper and lower directions at the inner part to form a hole(12) communicated with the steam discharging port, a plurality of ribs(14) projected around the hole at the upper surface, and a first rim(16), projected in a ring type, positioned at an outside of the rib. The second member, which a second rim(26) is projected downward, is corresponded with the first rim at the lower surface, a plurality of discharging ports(22) positioned at the outside of the second rim to be penetrated to the upper and lower directions, and seals the upper surface of the first member to form a predetermined crack at the upper surface of the first member and the lower surface. |
