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

The invention provides a drain valve device capable of adjusting the amount of cleaning water, a cleaning water tank device and a flush toilet. Specifically, the drain valve device (24, 80) of the present invention has: a valve body (42, 86), which is installed above the drain port (32) provided on the bottom surface of the cleaning water tank (18), and moves in the up and down direction And the opening and closing drain; Float (48,88), is installed in this valve body and the reduction of the water level in the cleaning water water tank is linked and descends; And can change descending start time mechanism (50,64,90), is installed in The buoy can also change the start time of the valve body's descent.

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...
