Problems solved by technology

[0008] However, when the diameter of the drain port of the cleansing water tank of the integrated flush toilet is shared with the diameter of the drain port of the cleansing water tank of the separate flush toilet, it is unavoidable to change the drain flow path due to fixing the fittings. The problem of narrowness is that compared with the case where the fixing parts are not installed in the drainage flow path, the instantaneous flow rate of the cleaning water is reduced, and the cleaning performance of the toilet cannot be ensured sufficiently. Difficulty in applying a common drain valve device

Abstract

A discharge valve apparatus of the present invention includes: a discharge portion main body member attached to discharge opening, forming the inside of discharge flow path for guiding flush water from an inflow opening formed at one end thereof to an outflow opening formed at the other end thereof; a valve body for opening and closing the inflow opening of the discharge portion main body member; and an affixing portion, formed to project into the discharge flow path of a discharge portion main body member, for affixing the discharge portion main body member to a reservoir tank; wherein the inside surface of side wall portion in the discharge portion main body member at the same height as this affixing portion forms a curved portion, which curves outward so as to expand the cross-sectional area of the flow path.

Description

technical field [0001] The present invention relates to a drain valve device and an integrated flush toilet equipped with the drain valve device, in particular to a drain valve device installed in the drain port of a cleaning water tank and an integrated flush toilet equipped with the drain valve device The toilet and the cleaning water tank store the cleaning water used for cleaning the toilet. Background technique [0002] Conventionally, as a drain valve device installed in a drain port of a cleansing water tank for storing cleansing water used to clean a toilet, for example, as described in Patent Document 1, there is known a so-called device in which the cleansing water tank and the toilet body are integrally formed. The drain port of the wash water tank of the integrated flush toilet is fixed at two places of the drain valve body with fixing fittings such as bolts. [0003] In addition, generally speaking, in an integrated flush toilet, in order to ensure the cleaning...
