- present invention can be applied to a case where two electric motors each having one blower are installed.
- a device that controls the motor 55 for example, an inverter, can be installed in the air flow path to cool it.
- it is installed on the lid 150.
- FIG. 26 This figure is a longitudinal sectional view in a state where the blower is pulled downward.
- an opening for inserting a blower is provided on the lower surface of the silencer box 200.
- Other configurations are the same as those of the above embodiment.
- the exhaust duct unit 180 connected to the right side is not shown. For maintenance work, remove the exhaust duct unit 180, and then pull out the blower unit downward. Silencer box 200 remains attached to body 250.
- the frame 50 of the blower is installed on a plate (cover) 210 that covers an opening on the lower surface of the silencer box 200.
- the plate 210 is firmly configured. Fix plate 210 to silencer box 200.
- the blower is moved in the vertical direction, but it may be moved in the horizontal direction and stored. If the moving direction is the axial direction, the connection between the inlet and outlet of the blower can be simplified. In this case, the outlet of the blower should be directed toward Wakasen in the direction of movement. In addition, the motor should move along the rail.
- one electric motor is combined with two blowers and one silencer box. However, one electric motor can be combined with one silencer box. In this case, one silencer box would eventually have two openings for ventilation.
- the assembling work and the disassembling work can be easily performed.
