Abstract

A ventilation fan with lamp is used to be installed to a ceiling including an installation opening and comprises a housing, a fan module and a lamp module. The housing includes a first opening and a second opening, and the first opening is aligned with the installation opening. The fan module is disposed in the housing. The lamp module is fixed to the first opening by a plurality of elastic elements passing through the housing and includes a lamp cover, a base and a lens. The lamp cover includes a flange portion and a plurality of contact portions, the flange portion and the contact portions are disposed outside the installation opening of the ceiling. The lamp module is connected to the ceiling via the contact portions to make a gap between the lamp cover and the ceiling, and the gap serves as an air inlet of the ventilation fan.

First claim

What is claimed is:

1 . A ventilation fan with a lamp for installation in a ceiling, the ceiling having an installation opening; the ventilation fan comprising:
a housing including a first opening and a second opening, wherein the first opening is aligned with the installation opening; a fan module disposed in the housing; and a lamp module fixed to the first opening by a plurality of elastic elements passing through the housing and including:
a lamp cover including a flange portion and a plurality of contact portions connected to the flange portion, wherein the flange portion and the plurality of contact portions are disposed outside the installation opening of the ceiling, the ceiling is disposed between the housing and the flange portion, the plurality of contact portions are disposed between the ceiling and the flange portion, the lamp module is connected to the ceiling via the plurality of contact portions so as to make a gap between the lamp cover and the ceiling and serving as an air inlet of the ventilation fan;
a base disposed on the lamp cover; and
a lens disposed opposite to the base and connected to the lamp cover.

2 . The ventilation fan as recited in claim 1 , wherein the housing further includes two extension portions which have slots, and the two extension portions are disposed inside the housing.

3 . The ventilation fan as recited in claim 2 , wherein the elastic element is a metal element with V-shaped structure and the bending portion thereof is connected to the lamp cover.

4 . The ventilation fan as recited in claim 3 , wherein the elastic element is disposed to pass through the slot.

5 . The ventilation fan as recited in claim 3 , wherein each of two ends of the elastic element has a hook structure fixed to the extension portions.

6 . The ventilation fan as recited in claim 1 , wherein ends of the plurality of contact portions connected to the ceiling are connected by a connection element.

7 . The ventilation fan as recited in claim 1 , wherein the fan module includes:
a fan casing including an inlet opening and an outlet opening which communicates with the second opening; an impeller disposed in the fan casing; and a motor connected to and driving the impeller to rotate.

8 . The ventilation fan as recited in claim 7 , wherein outer diameters of the motor and the impeller are less than an inner diameter of the first opening, respectively.

9 . The ventilation fan as recited in claim 7 , wherein at least half of the volume of the fan module is on a projection plane of the first opening.

10 . The ventilation fan as recited in claim 1 , wherein the height of the gap is between 5 mm and 15 mm.

11 . A ventilation fan with a lamp, comprising:
a housing including a first opening, a second opening and at least an extension portion which have slots, wherein the extension portion is disposed in the housing; a fan module disposed in the housing; and a lamp module disposed through the first opening and including:
a lamp cover including a flange portion and a plurality of contact portions connected to the flange portion, wherein both the flange portion and the plurality of contact portions are disposed outside the housing, each of the plurality of contact portions has a sidewall without being connected to an outer edge of the flange portion, the plurality of contact portions form a plurality of gaps therebetween, and the gaps serve as a height of each of the plurality of contact portions is equal to a vertical width of an air inlet of the ventilation fan;
a base disposed on the lamp cover; and
a lens disposed opposite to the base and connected to the lamp cover;
wherein the lamp module is fixed to the first opening by a plurality of elastic elements passing through the slots.

12 . The ventilation fan as recited in claim 11 , wherein ends of the plurality of contact portions away from the flange portion are connected by a connection element.

13 . The ventilation fan as recited in claim 11 , wherein the fan module includes:
a fan casing including an inlet opening and an outlet opening which communicates with the second opening; an impeller disposed in the fan casing; and a motor connected to and driving the impeller to rotate.

14 . The ventilation fan as recited in claim 13 , wherein outer diameters of the motor and the impeller are less than an inner diameter of the first opening, respectively.

15 . The ventilation fan as recited in claim 11 , wherein at least half of the volume of the fan module is on a projection plane of the first opening.

16 . The ventilation fan as recited in claim 11 , wherein the height of each of the plurality of the contact portions is between 5 mm and 15 mm.

17 . A ventilation fan with a lamp, comprising:
a housing including a first opening, a second opening and at least an extension portion which have slots, wherein the extension portion is disposed in the housing; a fan module disposed in the housing; and a lamp module disposed through the first opening and including:
a lamp cover including a flange portion and a plurality of contact portions connected to the flange portion, wherein both the flange portion and the plurality of contact portions are disposed outside the housing, each of the plurality of contact portions has a sidewall without being connected to an outer edge of the flange portion, the plurality of contact portions form a plurality of gaps therebetween, and the gaps serve as a height of each of the plurality of contact portions is equal to a vertical width of an air inlet of the ventilation fan;
a base disposed on the lamp cover; and
a lens disposed opposite to the base and connected to the lamp cover;
wherein the lamp module is fixed to the first opening by a plurality of elastic elements passing through the slots; and the elastic element is a metal element with V-shaped structure and the bending portion thereof is connected to the lamp cover.
