Implementations of air deflectors may include a curved section coupled between a first and second sidewall. Air deflectors may also include a first magnet retainer extending from the first sidewall. The first magnet retainer may include a first retainer wall, a second retainer wall, and a retainer tab extending from the first sidewall and positioned between the first retainer wall and the second retainer wall. A first magnet may be positioned between the first retainer wall and the second retainer wall. The air deflector may also include a second magnet retainer extending from the second sidewall and a second magnet coupled with the second magnet retainer. The first retainer wall and the second retainer wall may each include a ledge directly coupled to the first magnet. The first magnet may be coupled between the retainer tab and each ledge of the first retainer wall and the second retainer wall.

A vent cover for an air duct having (a) a top surface with an aperture, (b) an actuating member extending through the aperture and operably connected to a magnet selectively engageable with the air duct, and (c) a bias means for urging the magnet towards the air duct, the actuating member movable between a securing position and a releasing position, wherein in the securing position the bias means urges the magnet towards the air duct, and in the releasing position the actuating member moves the magnet away from the air duct to allow the vent cover to be removed from the air duct.

A heating, ventilation, and air conditioning (HVAC) system actuator including a stator magnet and a rotor magnet. The rotor magnet turns an axle connected to an airflow door such that rotation of the axle moves the door and generates waveforms. The number of waveforms generated corresponds to how much the axle has rotated. The stator magnet is magnetized to a saturated state, thereby providing the waveforms with a consistent shape that is consistently detectable by a climate control pulse count module.

A wall exhaust vent (e.g., for a dryer or other HVAC system) can include a housing defining a vent opening, and one or more bumpers on or at least partially within the housing and configured contact a door of the wall exhaust vent in a closed position. The one or more bumpers can include a bumper body, and a magnet disposed at least partially within the bumper body that is configured to magnetically interact with the door of the wall exhaust vent to bias the door to the closed position.

An air purifier may include a main body and a floating body configured to levitate above the main body via magnetic force. The main body may include a fan to suction air, a filter to filter suctioned air, and a discharge port provided on an upper surface through which air is discharged. The floating body may be provided above the discharge port and further disperse discharged air. The main body may have a magnetic force generator to provide a magnetic force that levitates the floating body, and may also have a magnetic force adjustor configured to maintain a stable position of the floating body.

A wall exhaust vent (e.g., for a dryer or other HVAC system) can include a housing defining a vent opening, and one or more bumpers on or at least partially within the housing and configured contact a door of the wall exhaust vent in a closed position. The one or more bumpers can include a bumper body, and a magnet disposed at least partially within the bumper body that is configured to magnetically interact with the door of the wall exhaust vent to bias the door to the closed position.

A programmable vent system is provided. The programmable vent system may have at least one vent unit and at least one central housing unit. The programmable vent system may allow a user to individually monitor and control the at least one air vent located within a building or home. Each programmable vent may be controlled via a wireless communication, such as a remote control, a Bluetooth device or may be controlled wirelessly through a cell phone signal. The present programmable vent system may increase the efficiency of energy within the building or home by directing hot or cool air only to proper areas within the building or home.

A vent assembly for a blowing device includes a frame defining an air outlet therein, and an air deflector pivotally provided in the air outlet and configured to open or close the air outlet. The air deflector is provided with a first attraction member, and the frame is provided with a second attraction member in a corresponding position and configured to attract the first attraction member when the air deflector is closed, such that the air deflector is arranged in a plane where the air outlet is.
