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.

A ventilator includes an opening formed on a bottom surface, a rectangular frame provided with a flange, a volute provided with a fan motor inside, and a connector connected to an air outlet of the volute. Four side surfaces of the frame excluding the top surface and the bottom surface tilt towards the outer lower side in a direction from the top surface to the bottom surface, and the opening area of the bottom surface is larger than that of the top surface. The ventilator saves packaging and installation costs, and further facilitates installation between the roof and the ceiling.

Ventilation fan

A ventilating fan, includes a housing having an opening at a bottom surface thereof, a casing disposed in the housing, fan blades and a motor disposed in the casing, and a wiring box fixed on the casing and composed of a box body and a cover. The wiring box is fixed on the casing through a fixing structure, the fixing structure includes a first fixing means and a second fixing means, and the first fixing means includes a screw fixing structure, and the second fixing means includes an engaging fixing structure. An advantage of the ventilating fan lies in that, while preventing a user from detaching the wiring box manually, the ventilating fan has reduced components and can simplify operating steps during fixing the wiring box on the casing, and is thereby less time consuming.

A ventilation fan with illumination includes a housing, a fan, and lighting equipment in the housing. The housing includes a first opening communicating with an air outlet, the first opening communicating with a duct, and a second opening that communicates with an interior space, The lighting equipment includes a light, a cover in the housing that surrounds the light periphery, the cover reflecting light and transmitting the light into the space through the second opening, and a restrictor that restricts passage of air between the light periphery and the lighting cover. An air intake gap is provided between a lower end of the cover and an edge of the second opening and introduced through the second opening and the air intake gap, is discharged through the first opening into the duct, the edge of the second opening being located below the lower end of the cover.

The ceiling mounted ventilation fan with illumination employs a configuration in which a second opening for guiding light from an illumination unit into the room is formed in a lower part of a main housing and in which a air inlet on a fan casing of a fan unit is provided so as to open toward upper part of the main housing. Thus the air inlet of the fan unit opens in a direction opposite to the second opening communicating with inside of the room. As a result, sounds such as operation noises from the fan unit that are transmitted to outside of the fan unit chiefly through the air inlet can be made to resist being transmitted through the second opening into the room, so that the noises can be reduced.

Disclosed is a fixing structure for ventilator cover spring, comprising a fixing component, a connector, a movable part, and a cover spring. The fixing component is a U-shaped protrusion formed on a cover and has a top wall and two leg walls, a first opening and a second opening are respectively formed in the two leg walls. Two cuts are formed at two ends of the connector, wherein each cut is provided with a tongue, the connector being inserted through and fixed in the first opening and the second opening. The movable part has a head portion and a foot portion, wherein the head portion is fixed on the connector, and the foot portion extends toward the top wall. The cover spring is fitted over the foot portion and is confined on the foot portion.

A ceiling mounted ventilation fan with illumination capable of suppressing conduction of noise to inside of a room is provided. In the fan, a restriction member is provided for restricting passage of air between a lighting cover and a periphery of a lighting part, the lighting cover having a reflecting surface for reflecting light from the lighting part to lead the light to the inside of the room. A gap for air intake is formed between a lower end of the lighting cover and an edge of the indoor-side opening. Thus, air introduced into the main housing through the gap is discharged into the duct by the fan unit and conduction of noises produced by the fan unit to the room inside with the noise directivity enhanced in the lighting cover can be suppressed by the restriction member, so that conduction of noise to the room inside can be suppressed.
