  The first water level detection member 19 and the second water level detection member 20 are adjacent to each other in the same direction as the mounting / removing direction A of the tray 10. The distance B between the second water level detection member 20 and the handle 27 is longer than the distance C between the first water level detection member 19 and the handle 27. The first water level detection member 19 and the second water level detection member 20 are disposed on the other side (left side in FIG. 10) in the mounting / removing direction A of the tray 10. When the tray 10 is inserted into the lower portion of the main body case 1 with the handle 27 of the tray 10, the first side is the front end side in the insertion direction and the other side (left side in FIG. 10) in the mounting / removing direction A of the tray 10. The handle 27 on one side (right side in FIG. 10) in the mounting / removing direction A of the tray 10 is higher than the water level detection member 19 and the second water level detection member 20.

When the tray 10 is attached to the lower portion of the main body case 1 with the handle 27 of the tray 10, the second water level detection member 20 is the other side than the side provided with the handle 27 which is one side in the mounting / removing direction A of the tray 10. Since the fourth area 25 on which the is mounted is lowered, water tends to be accumulated in the fourth area 25 along the other side surface of the tray 10.

  Further, the first water level detection member 19 and the second water level detection member 20 are disposed adjacent to the side surface on one side (lower side in FIG. 10) of the tray in the direction orthogonal to the mounting / removing direction A of the tray. did. The third area 24 in which the first water level detection member 19 is mounted and the fourth area 25 in which the second water level detection member 20 is mounted are orthogonal to the mounting / removing direction A of the tray 10 Adjacent to the side of one side (lower side in FIG. 10) of the tray 10 in the direction. Thus, when the water in the tray 10 is drained, one side (the lower side in FIG. 10) of the tray 10 in the direction orthogonal to the mounting / removing direction A of the tray 10 is held by holding the handle 27. Lowering from the other side (upper side in FIG. 10) of the tray 10 in the direction orthogonal to the mounting / removing direction A allows water to be simultaneously drained from the third area 24 and the fourth area 25 and facilitates the drainage operation .

  Further, the electrodes were disposed adjacent to the side surface on one side (lower side in FIG. 10) of the tray 10 in the direction orthogonal to the mounting / removing direction A of the tray 10.

  The fifth area 26 in which the electrodes are mounted is adjacent to the side surface on one side (the lower side in FIG. 10) of the tray 10 in the direction orthogonal to the mounting / removing direction A of the tray 10. Thus, when the water in the tray 10 is drained, one side (the lower side in FIG. 10) of the tray 10 in the direction orthogonal to the mounting / removing direction A of the tray 10 is held by holding the handle 27. Lowering from the other side (upper side in FIG. 10) of the tray 10 in the direction orthogonal to the mounting / removing direction A, water can be drained simultaneously from the third area 24, the fourth area 25 and the fifth area 26, Drainage work becomes easier.

  As shown in FIG. 1, the notification unit 21 is a drainage lamp 28. When the water level in the tray 10 falls below the first water level detection member 19, the drain lamp 28 blinks by the control unit 16, and the tray 10 and the tank 11 are removed from the body case 1, and the tray 10 is attached to the body case 1 When the water level in the tray 10 falls below the second water level detection member 20, the control unit 16 turns off the drainage lamp. Thereby, the user can be notified of the water level in the tray 10.
