An incubator comprises an incubator chamber defined by a bottom part and a top casing covering a bed area of the bottom part. The incubator comprises an air treatment and circulation device for treating air and circulating it through the chamber, said air treatment and circulation device including a ventilator. The air treatment and circulation device is connected to chamber inlet openings which are arranged along one or more sides of said bed area, allowing treated air to flow from the treatment and circulation device into the chamber. The air treatment and circulation device furthermore is connected to at least one chamber outlet opening allowing air to flow out from the chamber to the treatment and circulation device. The air flows in the incubator are routed such that noise is reduced and no high air flow speeds occur near the infant in the incubator.

A noise-reducing valve structure includes a unitary spindle-shaped body having a central lumen for receiving a fluid flow and a poppet member, the body having an inner diameter adjacent the central lumen and an outer diameter and a circumferentially and axially distributed plurality of radial passages adapted to be opened and closed in accordance with a guided position of the poppet member, the plurality of radial passages extending through the spindle-shaped body from the inner diameter to the outer diameter and having a gradually increasing area from the inner diameter to the outer diameter.

A movable air conditioner includes an air conditioner main body, an air conditioning unit installed in the air conditioner main body and configured to generate a cold air or a warm air, a control unit configured to control the air conditioning unit, and an attachment/detachment unit configured to detachably attach the air conditioning unit to the air conditioner main body so that the air conditioning unit can be optionally detached from the air conditioner main body and used independently.

An air vent structure includes a frame arranged at an air outlet or an air inlet of a box body, and a plurality of plates. In cross section, each of the plates is a bent structure and includes a first flat portion, an upslope portion and a downslope portion. The first flat portion is fixed to the frame and extends in a direction away from the frame, the plate then extending upward to form the upslope portion. A top of the upslope bends downward to form the downslope portion, and the height of the downslope portion is smaller than the height of the upslope portion. The air vent structure can ensure that hot air flow passes smoothly through the air outlet, and also ensure that the hot air flow is blown out in a horizontal direction. A box-type inverter having the air vent structure is also provided.

A flow-straightening device at a coupling portion between: an air supply chamber adjacent to a coating chamber and supplying air to the coating chamber via a filter provided at a boundary wall between the air supply chamber and the coating chamber; and an air supply duct supplying air to the air supply chamber in a direction along the boundary wall. When a direction parallel to the boundary wall and perpendicular to the air supply chamber width direction is an air supply chamber depth direction; and a direction perpendicular to the boundary wall is an air supply chamber thickness direction, the device includes a plurality of fins arranged in the air supply chamber width direction and the air supply chamber depth direction and juxtaposed to each other to be spaced apart from each other in the chamber thickness direction.

A venting grate includes a main portion, a first venting area, and a second venting area. The first venting area is defined by first, second, third, and fourth edges. Each of the first, second, third, and fourth edges extend from the main portion. The second venting area is defined by fifth, sixth, seventh, and eighth edges. Each of the fifth, sixth, seventh, and eighth edges extend from the main portion. The third edge and the fifth edge extend away from the main portion of the venting grate and angle together to form a pointed edge between the first and second venting areas.

Disclosed is a dehumidifier capable of dehumidifying an indoor space more efficiently. The present dehumidifier comprises: a body having an intake opening and a discharge opening; a blowing fan arranged inside the body so as to draw air into the body through the intake opening and to discharge the same to the outside through the discharge opening; a fan case having a duct arranged inside the body so as to provide a channel through which the air drawn by the blowing fan flows to the discharge opening; a heat exchanger arranged inside the body so as to remove moisture from the air that has flown into the body; and fixed blades that are fixedly installed inside the duct so as to split the air, which has flowed through the channel, to a plurality of discharge paths.

An air treatment system includes an air handling unit to direct air into a building structure; a sensor to detect the presence of a target material and produce a signal indicative of the detection of a target material greater than a threshold amount; and a control system to control the air handler based on the signal from the sensor.

An incubator comprises an incubator chamber defined by a bottom part and a top casing covering a bed area of the bottom part. The incubator comprises an air treatment and circulation device for treating air and circulating it through the chamber, said air treatment and circulation device including a ventilator. The air treatment and circulation device is connected to chamber inlet openings which are arranged along one or more sides of said bed area, allowing treated air to flow from the treatment and circulation device into the chamber. The air treatment and circulation device furthermore is connected to at least one chamber outlet opening allowing air to flow out from the chamber to the treatment and circulation device. The air flows in the incubator are routed such that noise is reduced and no high air flow speeds occur near the infant in the incubator.
