Abstract: An indoor air purifier has a base and a container on the base with a layer of soil supported above a lower water bath occupying the bottom of the container. The container is fitted on top of the base such that the container can freely rotate upon the base. Room air is drawn into the base and is passed from the base into the bottom of the container through a duct connected between the two. Air passing from the base is directed downwardly into the water bath before passing upwardly into the soil layer. The air passes through the soil layer and is discharged from the soil's surface back into the room. Contaminant gases and particulates are removed from the air through contact with the soil layer and are metabolized by microorganisms contained within the soil, producing carbon dioxide and water. The water bath humidifies the air being passed through it and maintains a stable degree of moisture in the lower portion of the soil layer. Water lost through evaporation is replenished through a sleeve passing downward from the soil's surface to the water bath. A water bottle inverted within the sleeve maintains a substantially constant water level. Plants may be grown in the soil layer to aid in purification and to provide an attractive room decor.

Abstract translation: 室内空气净化器在基座上具有基部和容器，其中一层土壤被支撑在位于容器底部的下部水浴上方。 容器安装在基座的顶部，使得容器可以在基座上自由旋转。 室内空气被吸入基座，并通过连接在两者之间的管道从基座通入容器的底部。 从底部通过的空气向下流入水浴，然后向上通入土壤层。 空气通过土层，从土壤表面排出回到房间。 污染气体和颗粒物通过与土壤层接触而从空气中除去，并被土壤中包含的微生物代谢，产生二氧化碳和水。 水浴加湿通过它的空气，并在土壤层的下部保持稳定的湿度。 通过蒸发而损失的水通过从土壤表面向下流到水浴的套筒来补充。 在套筒内倒置的水瓶保持基本恒定的水位。 植物可以在土壤层中生长以帮助净化并提供有吸引力的房间装饰。
