A dishwashing appliance includes a tub defining a wash chamber. An inlet is defined in the tub and provides air flow into the wash chamber. An air handler selectively urges air through the inlet in one of a first direction and a second direction different from the first direction. The air flows from the inlet and through the wash chamber of the tub along a first defined path when the air handler urges air through the inlet in the first direction, and the air flows from the inlet and through the wash chamber of the tub along a second defined path when the air handler urges air through the inlet in the second direction.

A system for heating, drying or curing an object, the system comprising a housing having a first wall and at least one second wall adjacent the first wall. The first wall and at least one second wall define an interior for holding an object to be heated, dried or cured. The system also includes an air plenum adjacent to, covering and disposed inward from the first wall, and at least one air plenum opening in the air plenum to supply air into the interior. A fan is disposed in the one air plenum opening. The system also includes a ductwork assembly adjacent to, covering and disposed inward from the second wall. The ductwork assembly is in air-communication with the air plenum, and has a ductwork opening so that substantially all air circulation in the interior is between the air plenum opening and the ductwork opening.

A mixing chamber assembly for mixing burner output with kiln return air. A first vertical duct that receives kiln return air from the first return duct when the kiln is operated in a first mode and receives kiln return air from the second return duct when the kiln is operated in a second mode. A second vertical duct in fluid communication with the first vertical duct so that the kiln return air enters the first vertical duct, travels upward, and changes direction to then travel downward in the second vertical duct to pass downward into a dispersion chamber to provide downward movement of the kiln return air. The dispersion chamber having a hot duct discharge to convey burner output laterally above a delay table surface. The downward movement of the kiln return air colliding with the burner output to provide mixing of the kiln return air with the burner output.

The invention relates to an installation for the thermal drying of wood by CO.sub.2 sequestration, having at least one CO.sub.2 atmosphere drying module comprising: a drying chamber (1), means of supply of CO.sub.2 (3), means of heating (2), means of gas circulation (4), means of recycling (600) of the CO.sub.2, metrological means (5), means of supply of CO.sub.2 (3), and a computerised control system (6), characterised in that the means of gas circulation (4) comprise a flow reversal module configured to allow the circulation of CO.sub.2 in a first direction forming a closed-loop circulation duct for the CO.sub.2 gas mixture, and in a second direction of circulation opposite to the first direction, capable of rendering uniform the thermal distribution in said drying chamber (1).

The invention relates to an implemented method for thermally drying wood comprising the following stages: Acquiring the metrological data and parameters of the wood to be dried (S1); saturating (S2) the drying chamber (1) with CO.sub.2 Adjusting the humidity of the wood (S3) by heating reheating (S4) the CO.sub.2 circulating in the drying chamber (1) in a first phase, and subsequently reheating the CO.sub.2 circulant in the drying chamber (1) in a second phase until the measured humidity of the wood reaches a chosen intermediate target value Hi, Reducing (S5) the temperature of the heating chamber (1) down to a chosen third stabilisation setpoint temperature T3, Reducing the temperature of the heating chamber (1) in a second phase (S6) And the dried wood obtained directly using the method according to the invention.

The downward movement of the kiln return air colliding with the burner output to provide mixing of the kiln return air with the burner output.

The invention relates to a continuous drying device (2) for drying hygroscopic goods to be dried, comprising a drying chamber (4) for receiving the goods to be dried, comprising conveying means for conveying the goods to be dried from an inlet (6) to an outlet (8) of the drying chamber (4) during the drying process, in a conveying direction (10), and comprising air-conditioning means for setting a drying climate in the drying chamber (4) during the operation of the drying device (2), such that a plurality of climate zones (12 to 22), in which different zone climates can be set or are set or arise, are formed in succession in the conveying direction.
