A hand dryer includes a nozzle for blowing out an airflow toward a drying space, which is open at the front and the left and right sides so that hands can be freely inserted and withdrawn, and a wind direction changing part that changes a direction of the airflow blown out vertically downward from the nozzle. The wind direction changing part is so positioned as to be shifted rearward in a front-back direction from a position on an extension of a blow direction of the nozzle. While the airflow is being blown out vertically downward from the nozzle, the wind direction changing part and the nozzle do not directly face each other.

The present disclosure provides a surface cleaning apparatus that includes a recovery system that extracts liquid and debris with a drying cycle in which forced air flows through a recovery pathway of the recovery system to dry out components that remain wet and/or retain moisture after normal operation of the apparatus. The post-operation drying cycle can dry out components such as an agitator or brushroll, a brush chamber, a suction nozzle, a recovery tank, a filter, and any of the various conduits, ducts, and/or hoses fluidly coupling components of the recovery system together.

Roof drying processes and associated systems. A representative process includes drawing moisture-laden air from within the internal structure of a roof via a vacuum blower, a extraction insert and an extraction manifold, and removing moisture from the moisture-laden air via a dehumidifier. The dry air can be directed back into the roof through an injection insert and an injection manifold.

The present disclosure relates to a device and a system for gas injection in cavities of building structures, particularly for drying, decontaminating or drying and decontaminating building structures. The present disclosure also relates to a device and a system for gas extraction from cavities of building structures, particularly for drying, or for drying and decontaminating building structures. The present disclosure also generally relates to a system for monitoring parameters of a gas injection/extraction process using the device and system provided herein.

A lighted dryer assembly for a vehicle wash system including a housing portion, having a head portion, a body portion, and an outlet portion. The head portion includes an air inlet portion for drawing air into the head portion and an outlet for passing the air to the body portion. The outlet portion has a plurality of exit nozzles that are configured to emit high velocity air therefrom for removing water from an exterior surface of a vehicle while disposed in a vehicle treatment area. The body portion includes an upper portion where air is received from the head portion and a lower portion disposed remote from the upper portion. A light source is disposed within the housing portion and configured to emit light that can be seen by a vehicle disposed in the vehicle treatment area.

A grain dying system for a grain bin that includes a heating unit arranged in a proximity of the grain bin and ducting connected at one end to the heating unit and another end to a grain drying adaptor. The grain drying adaptor is connected at one end to the ducting and at another end to a fain unit of an aeration system for the grain bin. The fan unit is attached to the grain drying adaptor. The grain drying adaptor is configured to introduce a blend of heated air from the heating unit and ambient air from outside the grain drying adaptor into the aeration system of the grain bin.

An air vent attachment, such as for drying articles of clothing is provided. The air vent attachment includes a cage member having at least one air conduit extending from an inner surface to an outer surface, the inner surface abutting an exterior surface of an air vent and the outer surface distanced from the exterior surface of the air vent. A securing rod has an inner end and an outer end, the inner end having a securing member and the outer end retaining the cage member. A biasing member is positioned between the cage member and the outer end of the securing rod to bias the cage member toward the inner end of the securing rod.

A vibratory fluidized bed dryer includes a deck with a surface on which a bed of materials is formed, the deck having apertures through which air passes to fluidize the bed of materials on the deck, a source of air coupled to the apertures in the deck to supply air to the bed through the apertures in the deck, and a vibration generator coupled to the deck. The deck has at least two zones, each zone having a different open area percentage, such that the air passing through each zone produces a different superficial velocity.

An air curtain generating device includes: a plurality of pairs of an air jet unit and an air suction unit placed opposite each other on both sides in a lateral direction of an inlet/outlet of a drying chamber, the plurality of the pairs being aligned up and down, the air suction units sucking air ejected from the air jet units to generate an air curtain; a first air guide provided to the air jet units in an upper part of the inlet/outlet to guide air ejected from the air jet units in a direction inclined inward of the drying chamber relative to the lateral direction of the inlet/outlet; and a second air guide provided to the air jet units in a lower part of the inlet/outlet to guide air ejected from the air jet units in a direction inclined outward of the drying chamber relative to the lateral direction.
