## Abstract

A bacteria removing water discharge device used for a water supply facility is provided. The device includes: a bacteria removing water generating part denaturing tap water to generate bacteria removing water; a bacteria removing water discharge part, the part including a water storage part storing the bacteria removing water temporally, a water discharge port discharging the bacteria removing water stored in the water storage part onto a water receiving part of the water supply facility; and a controller, the controller executing a bacteria removing mode discharging the bacteria removing water from the bacteria removing water discharge part to the water receiving part, and a residual water drain mode draining at least a portion of the bacteria removing water remained in the water storage part after executing the bacteria removing mode.

## Claims

### Claim 1

A bacteria removing water discharge device used for a water supply facility, the device comprising:
a bacteria removing water generating part denaturing tap water to generate bacteria removing water;
a bacteria removing water discharge part, the part including a water storage part storing the bacteria removing water temporarily, a water discharge port discharging the bacteria removing water stored in the water storage part onto a water receiving part of the water supply facility; and
a controller, the controller executing a bacteria removing mode discharging the bacteria removing water from the bacteria removing water discharge part to the water receiving part, and a residual water drain mode draining at least a portion of the bacteria removing water remaining in the water storage part after executing the bacteria removing mode,
wherein the controller vibrates the bacteria removing water discharge part in the residual water drain mode,
wherein the residual water drain mode includes a first vibration step, in the first vibration step the bacteria removing water discharge part is vibrated while changing a position of the water discharge port so that the bacteria removing water remaining in the water storage part is discharged onto the water receiving part, and
wherein the residual water drain mode includes a second vibration step, the second vibration step is executed after the first vibration step, in the second vibration step a vibration different from a vibration generated in the bacteria removing water discharge part in the first vibration step is generated in the bacteria removing water discharge part.

### Claim 2 (depends on 1)

The bacteria removing water discharge device according to claim 1, wherein
the controller moves the position of the water discharge port in multiple directions in the second vibration step, and
a range of movement of the water discharge port in the second vibration step is narrower than a range of movement of the water discharge port in the first vibration step.
