Abstract

A ceiling mounted ventilation fan includes a housing, a fan unit and lighting equipment installed in the housing. The housing including a first opening connected to an air outlet and communicating with a duct, and a second opening that communicates with a room interior. The lighting equipment includes an illumination unit, and a cover, that surrounds the illumination unit, and has a reflecting surface which reflects light from the illumination unit and guides the light into the room. The fan unit includes a fan and a casing positioned at a first position, spaced, from a second position that is above the second opening, the fan casing surrounding the fan and having an air inlet opening directed upwardly. Air is introduced through the second opening and through the air inlet into the fan unit and is discharged through into the duct by the fan unit.

First claim

What is claimed:

1 . A ceiling mounted ventilation fan with illumination comprising a housing, a fan unit and lighting equipment installed in the housing,
the housing comprising:
a first opening connected to an air outlet of the fan unit, the first opening configured to communicate with a duct, and
a second opening provided in a lower part of the housing so as to communicate with an interior of a room,
the lighting equipment comprising:
an illumination unit, and
a lighting cover attached to the housing and provided in the housing so as to surround the illumination unit, the lighting cover having a reflecting surface which reflects light from the illumination unit so as to guide the light through the second opening into the room,
the fan unit comprising:
a fan, and
a fan casing positioned at a first position, spaced, in a horizontal direction, from a second position that is above the second opening, the fan casing surrounding the fan, the fan casing having an air inlet opening directed upwardly, wherein
air is introduced through the second opening into the housing, and the introduced air is sucked through the air inlet of the fan casing into the fan unit and is discharged through the first opening into the duct by the fan unit.

2 . The ceiling mounted ventilation fan with illumination according to claim 1 , wherein
an electrical unit for the fan unit or the lighting equipment is positioned facing the second opening, on an inner surface of an upper wall of the housing, and the fan unit is provided in the housing so that a distance L 1 from the inner surface of the upper wall of the housing to the air inlet of the fan casing is greater than a height L 2 of the electrical unit.

3 . The ceiling mounted ventilation fan with illumination according to claim 2 , further comprising legs that support the fan casing on an inner wall surface of the lower part of the housing, wherein
the fan unit is movable between a placement position of the fan unit in the main housing and a maintenance position of the fan unit over the second opening by a sliding movement of the legs along the inner wall surface of the lower part of the housing.

4 . The ceiling mounted ventilation fan with illumination according to claim 3 , further comprising guides that are engaged with the legs so as to guide the sliding movement of the legs.

5 . A ceiling mounted ventilation fan with illumination comprising:
a fan unit, an illumination unit, a housing in which the fan unit and the illumination unit are installed, the housing having a first opening connected to an air outlet of the fan unit and configured to communicate with a duct, and a second opening provided in a lower part of the housing so as to communicate with an interior of a room, and a member having a shape of a circular truncated conical cylinder or a polygonal truncated prismoidal cylinder such that a size of lower end of the member is greater than a size of an upper end of the member, the member being attached to the housing so as to surround the illumination unit, the fan unit comprising:
a fan, and
a fan casing positioned at a first position, spaced, in a horizontal direction, from a second position that is above the second opening, the fan casing surrounding the fan, the fan casing having an air inlet opening directed upwardly, wherein
light from the illumination unit passes through the second opening of the housing into the room, and air is introduced through the second opening into the housing and the introduced air is sucked through the air inlet of the fan casing into the fan unit and is discharged through the first opening into the duct by the fan unit.

6 . The ceiling mounted ventilation fan with illumination according to claim 5 , wherein
an electrical unit for the fan unit or the illumination unit is positioned facing the second opening, on an inner surface of an upper wall of the housing, and the fan unit is provided in the housing so that a distance L 1 from the inner surface of the upper wall of the housing to the air inlet of the fan casing is greater than a height L 2 of the electrical unit.

7 . The ceiling mounted ventilation fan with illumination according to claim 6 , further comprising legs that support the fan casing on an inner wall surface of the lower part of the housing, wherein
the fan unit is movable between a placement position of the fan unit in the housing and a maintenance position of the fan unit over the second opening by a sliding movement of the legs along the inner wall surface of the lower part of the housing.

8 . The ceiling mounted ventilation fan with illumination according to claim 7 , further comprising guides that are engaged with the legs so as to guide the sliding movement of the legs.
