Embedded ventilation fan includes housing, decorative panel, inner lid, and air supply blower. Decorative panel includes front surface, rear surface, air supply slit opening, remaining region, and light transmission portion. Inner lid is provided between housing and decorative panel. Inner lid includes display unit including light emitting portion and first fitted portion. Rear surface includes first fitting portion. Light transmission portion transmits light emitted from light emitting portion, and light transmission portion is disposed directly above light emitting portion by fitting first fitting portion and first fitted portion to each other.

A room air purifier has a body with a frame at least partially defining an interior chamber and an opening to the chamber. A purification mechanism in the chamber includes one or more filters and one or more blowers. A panel is configured to removably mount to the body and cover the opening to the chamber. A base mounted to the body, and each leg of a set of legs is mounted to the base. A nonwoven fabric portion covers at least part of the body. The blower when activated generates an inflow through the nonwoven fabric portion and a filter, and an outflow though the body, all while hidden from view in what to an observer looks like an article of furniture.

An air conditioner and a control method thereof perform cooling through an outlet if room temperature or room humidity is high to reduce the room temperature or the room humidity, and closing the outlet to perform cooling at low velocity through an outlet hole if room temperature or room humidity reaches a predetermined value so that a user can little feel the wind velocity of cooling of the air conditioner, while maintaining indoor space at pleasant temperature or humidity. By performing cooling at low velocity through the outlet hole formed in the lower portion of the air conditioner, it is possible to cool the lower area of indoor space at pleasant temperature when a user is asleep.

When a front panel moves away from a front surface of a casing, a central part of the front panel is warped. An indoor unit of the present invention includes a casing, a front panel provided forward of the casing, and a drive mechanism moving the front panel away from the front surface of the casing. The front panel is curved so that its central part protrudes forward. The drive mechanism moves the front panel in a substantially horizontal direction.

Pliable-wall air ducts with internal expanding structures are disclosed. An example air duct system includes an air duct including a pliable sidewall. The example air duct system further includes a shaft including a first end and a second end. The shaft extends in a longitudinal direction along a length of the air duct with the first end coupled to a first point of the air duct and the second end coupled to a second point of the air duct. The first point is downstream of the second point. The pliable sidewall is to be held in tension in the longitudinal direction between the first and second points in response to compression in the shaft between the first and second ends.

Air outlet for a ventilation device, the ventilation device comprising at least an air outlet, an air supply means, and an air guiding device, wherein the air outlet includes a plate having air outlet openings, and wherein the air outlet is in the installed state foldably mounted to an interior paneling such that it can be folded out of the interior paneling to allow for accessing a space there-behind.

An air conditioner is provided that may include a setting unit to set a predetermined function to be embodied or displayed with lighting, a storing unit to store at least one illumination pattern information, a control unit to connect the function input by the setting unit to an illumination pattern stored in the storing unit, and a lighting unit to be lighted according to the illumination pattern information connected to the function by the control unit.

A protective barrier affixable to a curved substrate comprises a stack of two or more lenses, each of the two or more lenses including a polyethylene terephthalate (PET) film, a hard coat on a first side of the PET film, and an adhesive layer on a second side of the PET film opposite the first side. The stack of two or more lenses may have a modulation transfer function that exhibits a contrast value greater than 75% for a spatial resolution of one line-pair per 0.0003 radians at 65 degrees angle of incidence. Heat and pressure may be applied to conform the stack of two or more lenses to the shape of the curved substrate.

The disclosure discloses an aromatherapy humidifier, which includes a base, a shell, and a cover, which are superimposed sequentially. An atomizing container is arranged on the base. A water storage tank is arranged on the atomizing container. The atomizing container and the water storage tank are contained in the shell. The water storage tank supplies water for the atomizing container and is provided with a mist channel communicated with the atomizing container. The atomizing container is provided with an atomizing assembly for atomizing water into mist and an aromatherapy assembly for volatilizing essential oil. The cover is covered on the shell and the water storage tank, the cover is provided with a spray port communicated with the mist channel and a water inlet communicated with the water storage tank, the mist and the volatilizing essential oil float through the mist channel and the spray port to humidify air.

Example air ducts comprising pliable tubular sidewalls are provided with example internal frameworks that hold the duct in a generally expanded shape even when the duct is depressurized. The framework tensions the pliable sidewall material along the length of the ducts to keep the material taut. In some examples, the framework is restrained within the duct such that the duct's sidewall, being in tension, holds the framework in compression longitudinally. Thus, in the longitudinal direction, the duct is in tension and the framework is in compression. To prevent the framework from buckling under the compressive force, some example frameworks comprise a central longitudinal shaft with a plurality of radial spokes and rings that help hold the shaft straight. In some examples, the rings also help hold the duct radially expanded.
