Abstract
An insulated cover for a whole-house fan includes a base defining an opening for disposal over the whole-house fan, and first and second, oppositely disposed, ceiling doors each hingedly connected to the base. In a closed configuration the ceiling doors each sit at an acute angle with respect to a horizontal plane corresponding with a bottom surface of the base. The base and ceiling doors are formed from thermal insulation board.
Claims22
An insulated cover for a whole-house fan, comprising:
- a base defining an opening for disposal over the whole-house fan;
- and
- first and second, oppositely disposed, ceiling doors each hingedly connected to the base, wherein in a closed configuration the ceiling doors each sit at an acute angle with respect to a horizontal plane corresponding with a bottom surface of the base,
- wherein the base and ceiling doors are formed from thermal insulation board,
- springs configured to assist the ceiling doors in opening when the whole-house fan is on and to provide resistance against the ceiling doors returning from an open configuration to the closed configuration when the whole-house fan is off, the resistance being insufficient to prevent the ceiling doors from returning to the closed configuration under load of the weight of the doors when the whole-house fan is off wherein the base is connected to the ceiling doors by hinged brackets.
A kit for use in assembling an insulated cover for a whole-house fan, comprising:
- first and second thermal insulation board ceiling doors;
- first and second thermal insulation board side walls;
- front and rear thermal insulation board walls;
- four lower hinged bracket components;
- four upper hinged bracket components;
- four locking pins for coupling the upper hinged bracket components to the lower hinged bracket components;
- and
- springs configured to, after assembly of the insulated cover, assist the ceiling doors in opening when the whole-house fan is on and to provide resistance against the ceiling doors returning from an open configuration to a closed configuration when the whole-house fan is off, the resistance being insufficient to prevent the ceiling doors from returning to the closed configuration under load of the weight of the doors when the whole-house fan is off.
A method of insulating a whole-house fan, comprising the steps of:
- providing an insulated cover, the insulated cover comprising:
- a base defining an opening for disposal over the whole-house fan;
- and
- first and second ceiling doors each hingedly connected to the base, wherein in a closed configuration the ceiling doors each sit at an acute angle with respect to a horizontal plane corresponding with a bottom surface of the base,
- wherein the base and ceiling doors are formed from thermal insulation board;
- and
- disposing the insulated cover over the whole-house fan, whereby the ceiling doors are forced open from the closed configuration to an open configuration by air flow from the whole-house fan when the whole house fan turns on and return to the closed configuration to form an insulated cover around the whole-house fan when the whole-house fan turns off,
- wherein the insulated cover includes springs configured to assist the ceiling doors in opening when the whole-house fan is on and to provide resistance against the ceiling doors returning from the open configuration to the closed configuration when the whole-house fan is off, the resistance being insufficient to prevent the ceiling doors from returning to the closed configuration under load of the weight of the doors when the whole-house fan is off wherein the base is connected to the ceiling doors by hinged brackets.
