An embodiment of the present invention will be described below with reference to the drawings. An electric motor 2 is mounted within a main body frame 1 of a ventilation fan by a support arm 3. 4 is a blade attached to the electric motor 2 by a cap 5.

いる。尚１２はシヤツターである。 A cover 7 having a bell mouth portion 6 surrounding the outside of the blade 4 is removably provided on the front surface of the main body frame 1. A handle portion 8 is formed to hang down from the lower portion of the cover 7, and an oil pocket 9 is removably fitted into this attachment portion 8. The rear upper edge 10 of the oil pocket 9 is in contact with the lower surface of the cover 7. This rear upper edge 10 has a sloped portion 10 that slopes downward toward the inside of the oil pocket 9.
A is formed. Bell mouth part 6 from blade 4
The oil 11 scattered on the surface collects at the bottom of the bell mouth 6, flows down along the front surface of the cover 7, and
The oil passes through the rear upper edge 10 of the oil pocket 9 from the lower surface of the oil pocket 9 and is accumulated in the oil pocket 9. Note that 12 is a shutter.
このとき、従来のものは第３図に示すようにカ
バー７の下面に当接するオイルポケツト９の後方
上端縁１０は平面のため、油は、毛細管現象によ
り油がオイルポケツト９の後方に流出していた。 At this time, in the conventional case, as shown in FIG. 3, the rear upper edge 10 of the oil pocket 9 that comes into contact with the lower surface of the cover 7 is flat, so oil flows out to the rear of the oil pocket 9 due to capillary action. was.

うにカバー７の下面に接するオイルポケツト９の
後方上端縁１０に勾配部１０Ａを設け、この勾配
部１０Ａはオイルポケツト９の方に下り勾配とし
ているので、毛管現象による油の吸引力は勾配部
１０Ａの方が大きく、従つて油はオイルポケツト
９内に流れ、オイルポケツト９の外後方に流出す
ることはない。 However, in the case of the present invention, as shown in FIG. 2, a sloped portion 10A is provided on the rear upper edge 10 of the oil pocket 9 that is in contact with the lower surface of the cover 7, and this sloped portion 10A slopes downward toward the oil pocket 9. Therefore, the oil suction force due to capillary action is greater in the sloped portion 10A, so the oil flows into the oil pocket 9 and does not flow out to the rear of the oil pocket 9.
前記下りの勾配部１０Ａは、オイルポケツト９
の上外縁部全体に設けても差支えない。 The downward slope portion 10A has an oil pocket 9
It may be provided on the entire upper outer edge.

As described above, according to the present invention, in a ventilation door having an oil pocket, a sloped portion 10A that slopes downward toward the inside of the oil pocket is formed at the upper rear edge of the oil pocket that comes into contact with the lower surface of the cover. Therefore, oil dust is prevented from leaking to the rear of the oil pocket, and a ventilation door that does not stain the floor surface can be provided.
