(Embodiment 1)
FIG. 1 is a cross-sectional view showing the configuration of the air supply device 1. A cylindrical wind tunnel 3 having a diameter smaller than the diameter of the opening 2 is inserted into the cylindrical opening 2 communicating with the wall surface of the building from the indoor side, and a flange portion is provided on the indoor side of the wind tunnel 3. 4 is formed, and is fixed to the wall surface from the flange portion 4 by screws. An air supply air passage 5 that communicates the indoor side and the outdoor side is formed inside the wind tunnel 3, and, for example, a propeller fan and an air supply impeller 6 serving as the air supply impeller 6 are rotated in the air supply air passage 5. For example, an AC condenser motor as the air supply driving motor 7 to be driven and a motor fixing member 8 for holding the air supply driving motor 7 are provided. The motor fixing member 8 is connected to the wind tunnel 3 and fixed. On the other hand, the indoor side is provided with an indoor panel 9 that covers and conceals the opening 2 and is detachably connected to the flange 4 of the wind tunnel 3 so as not to be sealed. Is provided with an air supply opening 10 that is opened in a slit shape for introducing outside air into the room, and an indoor panel 9 is provided with, for example, a HEPA filter as an air supply cleaning filter 11 for removing dust. Here, the air supply port 10 may be provided in a gap between the indoor panel 9 and the flange portion 4 of the wind tunnel 3 instead of the front surface of the indoor panel 9, and supplies air along the wall surface on the indoor side. It is good also as a structure.

  With the above configuration, by rotating the air supply impeller 6, outdoor air is sucked into the wind tunnel 3, passes through the air supply impeller 6 and the air supply drive motor 7, and then passes through the air supply clean filter 11. Outside air is introduced into the room through the air supply port 10.

  Further, the first power supply line 12 wired inside the wall surface by the indoor wiring is connected to the power supply side connector 13 provided on the circumference of the wind tunnel 3 through the opening 2, while supplying air The second power supply line 14 for energizing the drive motor 7 is connected to a load-side connector 15 provided in the motor fixing member 8, and the supply-side drive motor 7 is engaged with the supply-side connector 13 by engaging the load-side connector 15. With the configuration in which electricity is supplied, when the user cleans the inside of the air supply device 1, the motor fixing member 8 is removed from the wind tunnel 3 after removing the indoor panel 9 and the air supply cleaning filter 11. Since the load side connector 15 is detached from the power source side connector 13 simultaneously with the removal, the motor fixing member 8, the air supply drive motor 7, and the air supply impeller 6 can be removed together from the wind tunnel 3.

  The air supply cleaning filter 11 is installed on the outdoor side of the air supply impeller 6, and after removing the motor fixing member 8, the air supply driving motor 7 and the air supply impeller 6, the air supply cleaning filter 11 is opened from the indoor side. The same effect can be obtained even if the configuration is removed.

  Therefore, since the inside of the air supply impeller 6 and the wind tunnel 3 can be easily cleaned, the dissatisfaction that it is difficult for the user to clean is eliminated, and the air supply impeller 6 and the wind tunnel 3 are regularly cleaned. Since the inside can be maintained in a clean state, dust is accumulated inside the air supply impeller 6 and the wind tunnel 3 and the ventilation performance is not increased, resulting in a reduction in ventilation performance, thereby saving energy. Further, as shown in the exploded perspective view of FIG. 2, by making the air supply impeller 6 detachable from the rotating shaft 16 of the air supply drive motor 7, the air supply impeller 6 can be cleaned alone. Therefore, the user can easily clean the air supply impeller 6.

  FIG. 3 shows an exploded perspective view of the wind tunnel 3 and the motor fixing member 8 and a detailed view of the connector. As shown in FIG. 3, the load side connector 15 provided in the motor fixing member 8 includes a claw portion 17 having convex shapes on both side surfaces, and a knob portion 18 that can be operated by the user from the indoor side. The motor fixing member 8 is held in the wind tunnel 3 by providing the hole portion 19 into which the claw portion 17 is caught. When removing the motor fixing member 8 from the wind tunnel 3, the tabs 17 on both sides of the load-side connector 15 are sandwiched to disengage the tab 17 from the hole 19, and the motor fixing member 8 is pulled out from the wind tunnel 3. Can be removed. With this configuration, the user can easily attach and detach the motor fixing member 8 from the wind tunnel 3 without using a tool.

  In addition, the inside of the wind tunnel 3 is tapered so that the outer diameter becomes narrower toward the outdoor side, while the guide portion 20 for positioning the motor fixing member 8 and the wind tunnel 3 is also at the same angle as the inside of the wind tunnel 3. With the taper shape, when the motor fixing member 8 is inserted into the wind tunnel 3 from the indoor side, the clearance between the inside of the wind tunnel 3 and the guide portion 20 is not likely to interfere with each other. By adopting a configuration in which the diameter of the guide portion 20 matches with the direction of the central axis 21 of the wind tunnel 3, the user can easily attach and detach the motor fixing member 8.

  Further, as shown in FIG. 1, by inserting the wind tunnel 3 into the opening 2, a space 22 is formed outside the opening 2 and the wind tunnel 3, and the airflow flowing from the outdoor to the indoor in the opening 2 is the wind tunnel 3. It also flows into the space 22 outside. Since the first power supply line 12 is wired inside the wall surface in the space 22 outside the wind tunnel 3, the rubber is used to seal the outside of the wind tunnel 3 and the opening 2 outside the first power supply line 12.
