The projecting portion 8 engages with the engaging claw 15 provided for the purpose, the handle 16 provided on the outer side surface of the side surface on which the engaging claw 15 is provided, and the side surface of the front panel 7 that faces the projecting portion 8. A notch hole 18 into which the engagement hole 17 and the hooking part 10 are inserted, and a shaft 19 formed with a width narrower than the clearance 9 are provided on the back side of the notch hole 18 of the front panel 7.

  Further, the engagement hole 17 has an inclined portion 20 that is substantially the same as the protrusion 8, the front side inclination 12, and the back side inclination 13.

  As shown in FIG. 4, the handle 16 is provided along the outer periphery of the side surface of the front panel 7 in a U-shaped rib shape that is open only on the back side of the front panel 7.

  Further, the side surface of the front panel 7 provided with the handle 16 is inclined so that the front side of the front panel 7 is deeper.

  When the front panel 7 is attached to the main body frame 6 in the above configuration, when the front panel 7 is pushed into the main body frame 6 in the position and orientation, the side surface of the front panel 7 is moved by the front side inclination 12 and the inclined surface 14. The shaft 19 is deformed to the outside of the protrusion of the hook portion 10, and when further pushed, the shaft 19 gets over the hook portion 10, and the deformation of the side surface of the front panel 7 returns to the original state. The projection 8 is accommodated in the engagement hole 17 almost simultaneously, and the inclined portion 20 and the back side inclination 13 are almost in contact with each other, so that the locking claw 11 and the engagement claw 15 are engaged almost simultaneously. As a result, the front panel 7 is in close contact with the indoor ceiling 1 and is held without rattling.

  Further, when removing the front panel 7 from the main body frame 6, if the handle 16 is pulled with a finger, the engagement of the locking claw 11 and the engagement claw 15 is disengaged, and the shaft 19 is further removed from the hooking portion 10 to remove the front panel 7. Panel 7 is removed.

By dropping and hooking the shaft 19 into the hook portion 10 having the shape, the front panel 7 is cantilevered and temporarily fixed, and does not fall on the floor surface.

  As described above, according to the first embodiment, the cylindrical portion 3 attached to the wind tunnel pipe 2 embedded between the indoor ceiling 1 and the outer wall so as to communicate between the indoor and the outdoor, and the cylindrical portion 3 A main body frame 6 provided with a flange portion 4 formed in a substantially square shape projecting in the radial direction on the outer periphery of the indoor side opening of the inner wall, and a rising portion 5 formed on the back side of the periphery of the flange portion 4, and a main body frame 6, a box-shaped front panel 7, a rising part 5 of the main body frame 6, a protrusion 8 provided closer to the front side of the main body frame 6, and a rear side on the same plane as the rising part provided with the protrusion 8 Protruding part 8 protrudes closer, has an indoor ceiling 1 and a clearance 9, and is provided with a hook part 10 formed and provided in an inverted L shape, and a rising part facing the rising part 5 provided with the protruding part 8 and the hook part 10. 5 for locking 11 and protrusions 8, front side inclination 12 and rear side inclination 13 provided on the front side and rear side of the main body frame 6, and inclined surface 14 provided on the front side of the main body frame 6 and the front panel of the hook portion 10. 7 is provided with an engaging claw 15 provided to hold the front panel 7 by engaging with the locking claw 11, and a handle 16 and a protrusion provided on the outer surface of the side surface provided with the engaging claw 15. And a notch hole 18 into which the hook 8 is inserted, and a shaft 19 formed to be narrower than the clearance 9 on the back side of the notch 18. Have. Thereby, when the front panel 7 is pushed into the main body frame 6, the side surface of the front panel 7 is deformed outward from the protrusion of the hook portion 10 by the front side inclination 12 and the inclined surface 14, and further pushed in. When the shaft 19 gets over the hook 10 and the deformation of the side surface returns to the original state, it is accommodated in the clearance 9 at the same time. At the same time, the projection 8 and the engagement hole 17 and the locking claw 11 and the engagement claw 15 are engaged. Since the front panel 7 is held, the front panel 7 can be easily mounted only by pushing in, and the cleaning and maintenance properties can be improved.

  Further, the engagement hole 17 may be configured to have the same shape including the inclined portion 20 having the same shape as the rear-side inclined 13 of the protrusion 8. Thereby, when the front panel 7 is held by the main body frame 6, the inclined portion 20 of the front panel 7 comes into contact with the rear side inclination 13 of the main body frame 6, and the front panel 7 is held by the main body frame 6. Therefore, the front panel 7 is brought into close contact with the indoor ceiling 1 and the effect of preventing the occurrence of rattling can be achieved.

  Further, since the handle 16 has a U-shaped rib shape, when the front panel 7 is viewed from the front, it looks like a substantially square shape, and when viewed from the diagonally lower side of the handle 16, the side surface is the handle 16. Therefore, when viewed from the front, there is no bulge, and when viewed from diagonally below the handle 16, it is possible to give a clean impression of the rib shape.

  Further, the side surface of the front panel 7 provided with the handle 16 is inclined so that the front side of the front panel 7 is deeper, thereby increasing the depth of the handle 16 without increasing the size of the front panel 7. Since the finger can be deeply placed on the handle 16, the front panel 7 can be removed more easily.

  In the embodiment, the wind tunnel pipe 2 embedded in the indoor ceiling 1 is attached. However, the same effect can be obtained even when the wind tunnel pipe 2 is embedded in the indoor wall. it can.

  Further, when the front panel 7 is attached to the main body frame 6, the front panel 7 is pushed into the main body frame 6 in the position and orientation, but the shaft 19 of the front panel 7 is hooked on the hook portion 10 of the main body frame 6. Later, the front panel 7 can be attached by pushing it in. At this time, the front panel 7 rotates while pulling in the direction in which the front panel 7 is brought into close contact with the indoor ceiling 1 or the indoor wall while the inclined portion 20 of the engaging hole 17 and the rear side inclined 13 of the protrusion 8 are substantially in contact. By moving and engaging claw 11 and engagement claw 15 are engaged, front panel 7 is brought into close contact with indoor ceiling 1 or the indoor wall and is held without rattling.

  The front panel 7 is made of a material that is easily deformed by an external force, such as PP resin, and the clearance 9 is preferably set so that the tip side has a width of the shaft 19 +1 mm to +2 mm. In this embodiment, the shaft 19 is About 2.5 mm and the clearance is about 4 mm. If it is too large, it will be difficult to get caught when it is dropped, and if it is too small, the shaft 19 will be difficult to get over the catching part 10 and will be difficult to attach.

  Further, the height of the protruding portion 8 is a height that does not protrude from the side surface of the front panel 7, for example, the thickness is 2 mm, and the gap between the rising portion 5 of the main body frame 6 and the side surface of the front panel 7 is 0.5 mm. The height is preferably about 2 mm.

  In addition, the height of the hooking portion 10 is limited to about 5 mm, that is, the width of the shaft 19 +2.5 mm, and it is possible to provide a gentle inclination so that the rear side protrudes more. This is preferable because the protrusion can be minimized and the appearance can be compatible.

  Further, the angle of the front side inclination 12 is preferably about 45 degrees. When the angle increases, it becomes difficult to deform the side surface of the front panel 7 outward when the front panel 7 is pushed in, and when the angle decreases, the rising portion 5 of the main body frame 6 increases. Therefore, the ventilator greatly protrudes from the indoor ceiling 1 or the indoor wall.

  In addition, the inclined surface 14 is preferably about 40 degrees, and the back side inclination 13 is preferably about 20 degrees. When the angle is increased, when the front panel 7 is attached, the front panel 7 is brought into close contact with the indoor ceiling 1 or the indoor wall. In addition, the sliding between the protruding portion 8 and the inclined portion 20 becomes worse, and sufficient adhesion cannot be obtained.

  Further, as shown in FIG. 6, the distance (a) between the root of the hooking portion 10 and the indoor ceiling 1 is +0 with respect to the distance (b) between the root of the rear side inclination 13 of the protrusion 8 and the indoor ceiling 1. About 5 mm is preferable, and when the dimensional difference is large, the shaft 19 is less likely to be caught by the hook 10 when the front panel 7 is dropped.

  The ventilator according to the present invention can improve the mountability of the front panel to the main body while holding the front panel to the main body with the hook structure and the engagement structure. It is also useful for air conditioners that perform cleaning and maintenance, front panel mounting structures such as natural air inlets, and the like.
