Claim:
A wasted water draining valve, comprising: a valve body having a bottom having a first side formed with a wasted water inlet channel and a second side formed with a wasted water outlet channel connected to the wasted water inlet channel, wherein: the wasted water inlet channel of the valve body is inclined relative to the wasted water outlet channel of the valve body; the wasted water inlet channel of the valve body is disposed at an inclined state and the wasted water outlet channel of the valve body is disposed at an inclined state; the wasted water outlet channel of the valve body has an upper end connected to an upper end of the wasted water inlet channel of the valve body; the wasted water inlet channel of the valve body has a lower end formed with a wasted water inlet hole, and the wasted water outlet channel of the valve body has a lower end formed with a wasted water outlet hole; a wasted water inlet tube having an upper end connected to the wasted water inlet hole of the wasted water inlet channel of the valve body; and a wasted water outlet tube having an upper end connected to the wasted water outlet hole of the wasted water outlet channel of the valve body; wherein the wasted water outlet channel of the valve body has a side formed with an oblique air vent directed upward in an inclined manner and connected to an ambient environment to connect the wasted water outlet channel of the valve body to the ambient environment to prevent wasted water in the wasted water outlet tube from flowing backward from the wasted water outlet channel of the valve body into the wasted water inlet channel of the valve body and the wasted water inlet tube and to prevent the wasted water from sputtering outward from the air vent during drainage.
