Problems solved by technology

[0005] However, in the above-mentioned conventional drain valve device, since the time for the valve body to open the drain port is always approximately constant, only a predetermined amount of flushing water can be supplied to the toilet body.
Since the amount of flushing water varies depending on the type of toilet, it becomes impossible to apply the drain valve device to other types of toilets

Abstract

A discharge valve apparatus attached to a reservoir tank in a reservoir tank apparatus for storing flush water. The discharge valve apparatus includes a valve body, attached to the top of a discharge opening provided in the bottom surface of a reservoir tank, for opening and closing the discharge opening by up and down movement thereof, a float, attached to the valve body, which drops in tandem with the drop in water level inside the flush water tank; and a variable drop start timing mechanism to make a drop start timing of the valve body variable.

Description

technical field [0001] The invention relates to a drain valve device, a cleaning water tank device and a flush toilet. Background technique [0002] Conventionally, there is known a flush toilet that cleans a toilet body with cleansing water stored in a cleansing water tank device. Although a drain valve device is used in this cleansing water tank device, as an example of the drain valve device, a drain valve device in which the valve body moves up and down in the vertical direction relative to the drain port in the cleansing water tank can be used. , so as to open and close the drain port. As such a drain valve device, there is known a drain valve device in which a float that applies buoyancy to the valve body is integrally formed with the valve body (for example, refer to Patent Document 1). [0003] In this conventional drain valve device, since the valve body descends in the vertical direction in conjunction with the reduction of the water level in the cleaning water t...
