The water supply unit 14 projects from the piping unit 6 into the main body case 2 and is arranged above the water storage container 13.

As shown in FIG. 7, the drainage water storage unit 7 has a drainage container 33 and a supply unit 34.

The drainage container 33 is a container for storing the electrolyzed water remaining in the water storage container 13 after generating hypochlorous acid by the electrolysis unit 16 for a predetermined time. The drainage container 33 has a substantially box shape with an opening on the top surface, and has a structure capable of storing water. The drainage container 33 is arranged below the water storage container 13 and below the main body case 2. The electrolyzed water remaining in the water storage container 13 is moved to the drainage container 33 by the supply unit 34.

The supply unit 34 has a pump 35, a connecting pipe 36, and a water discharge member 37.

The pump 35 pumps the water in the water storage container 13 and sends the water in the water storage container 13 to the connecting pipe 36. The pump 35 is arranged in the water storage container 13 and is connected to one end of the connecting pipe 36.

The connecting pipe 36 is a flexible pipe. As an example, the connecting tube 36 is made of a silicon tube. One end of the connecting pipe 36 is connected to the pump 35, and the other end of the connecting pipe 36 is connected to the water discharge member 37. The connecting pipe 36 extends upward from the pump 35 and is connected to the water discharge member 37.

Further, as shown in FIG. 8, the water discharge member 37 has a vertical pipe water channel 38 extending in the vertical direction and a left and right pipe water channel 39 extending in the horizontal direction on the upstream side of the vertical pipe water channel 38. The connecting pipe 36 is connected to the left and right pipe water channels 39. The water sent to the connecting pipe 36 by the pump 35 drops into the drainage container 33 through the left and right pipe water passages 39 of the water discharge member 37 and the upper and lower pipe water passages 38 in order.

Here, an operation in which the supply unit 34 moves the electrolyzed water remaining in the water storage container 13 to the drainage container 33 will be described. First, the user operates the operation unit 11, and the control unit operates the pump 35 based on the signal from the operation unit 11. The pump 35 operates, and the pump 35 pumps the water in the water storage container 13 and sends the pumped water to the connecting pipe 36. Since the connecting pipe 36 extends upward from the pump 35, the water sent to the connecting pipe 36 collects in the connecting pipe 36, and the water surface in the connecting pipe 36 gradually moves upward. Next, the water overflowing from the connecting pipe 36 flows into the water discharge member 37. The water flowing from the connecting pipe 36 is blown out from the connecting pipe 36 in the lateral direction through the left and right pipe water channels 39, and flows so as to hit the inner surface of the upper and lower pipe water channels 38. Finally, it flows downward in the upper and lower pipe water channels 38 and drops from the lower end of the upper and lower pipe water channels 38 into the drainage container 33.

The feature in this embodiment is the water channel of the water discharge member 37. The water discharge member 37 has a tubular upper and lower pipe water channel 38 in which the water channel extends in the vertical direction. The cross-sectional area of some of the upper and lower pipe channels 38 gradually decreases from the upstream to the downstream. As a result, water tends to collect in the upper and lower pipe water channels 38, the flow velocity of the water in the upper and lower pipe water channels 38 flowing out from the water discharge member 37 increases, the water tends to flow down continuously, and the dripping sound of water is generated intermittently. Can be suppressed.

Further, the connecting pipe 36 is connected to the water discharge member from the lateral direction with respect to the central axis of the upper and lower pipe water passages 38 of the water discharge member 37. As a result, as compared with the case where the water from the connecting pipe 36 is supplied in the direction of the central axis of the upper and lower pipe water channels 38, the water from the connecting pipe 36 once hits the inner surface of the upper and lower pipe water channels 38, so that the upper and lower pipe water channels 38 It becomes easy to collect in 38, and it becomes easy to flow down continuously.

Further, the lower end edge 38a of the upper and lower pipe water channels 38 of the water discharge member 37 is inclined. As a result, the water droplets adhering to the inner surface of the upper and lower pipe water channels 38 are likely to collect at the lower end edge 38a, and it is possible to suppress the intermittent generation of water dripping noise.

Further, the cross-sectional area of the water channel at the lower end edge 38a of the upper and lower pipe water channels 38 is the same as the cross-sectional area of the water channels in the horizontal plane above the upper and lower pipe water channels 38. It is considered that this alleviates the pressure difference between the upper part and the lower part of the upper and lower pipe water channels 38 and improves the drainage.

Further, in the lower end edge 38a of the upper and lower pipe water passage 38 of the water discharge member 37, the tip of the lower end edge 38a of the upper and lower pipe water passage 38 is arranged on the downstream side in the direction in which the water in the pipe flows. As a result, the water from the connecting pipe 36 once hits the inner surface of the upper and lower pipe water channels 38 on the downstream side in the direction in which the water in the pipe flows. Since the tip of the lower end edge 38a of the upper and lower pipe water channels 38 is arranged below the inner surface, it is easy to gather at the lower end edge 38a, and it is possible to suppress the intermittent generation of water dripping sound.

The present invention is suitable as an air conditioner for removing microorganisms floating in space.
