摘要：
The present invention relates to a dryer (1) comprising a body (2), an air duct (3) which is disposed in the body (2) and which provides the air circulation during the air cycle, and a filter (7) with a 3D fabric structure composed of various layers.
技术功效语段：
[0007]The dryer, preferably with a heat pump, realized in order to attain the aim of the present invention and explicated in the claims, comprises a body and an air duct which is disposed in the body so as to ensure the circulation of the air during the air cycle. Said air duct contains all the sub-components through which the process air passes such as front bearing housing, area in front of or behind the heat exchanger, the airflow duct, the drum inlet and outlet, and forms an airflow path to direct the air. The dryer comprises a filter disposed in the air duct perpendicularly to the airflow direction and having a breathable upper layer which is manufactured from fabric, a breathable lower layer which is manufactured from fabric and which is positioned parallel to and at a distance from the upper layer, and a spacer layer in the form of spacer yarns which is disposed between the lower layer and the upper layer and which ensures air passage. The fabrics forming the lower and upper layers can be manufactured by knitting or weaving. By means of said three-layered structure known as 3D (spacer) fabric, a high filtering performance is obtained with minimal airflow losses with respect to 2D fabrics during the cycle in the dryer, and high strength is ensured which provides a long economic life. Moreover, since the air flow loss is low, the energy consumption of the dryer accordingly decreases, providing energy efficiency.
[0008]In an embodiment of the present invention, the dryer comprises the filter having the upper layer which has a lower porosity than or equal porosity to the lower layer. When the upper layer is considered as the first surface encountered by the process air in the dryer while entering the filter, a more efficient filtering performance is provided with less air flow loss by means of the upper layer having a lower or equal porosity with respect to the lower layer.
[0009]In an embodiment of the present invention, the dryer comprises the filter having the spacer layer with spacer yarns arranged as crosswise (XX), parallel to each other (II) or as a crosswise-parallel mixture. Thus, the fibers collected in the spacer layer can be easily removed or cleaned. Preferably, depending on the location of the filter in the dryer, said structures may have parallel (II) spacer yarns where the fluff is heavily collected and crosswise (XX) spacer yarns where the fluff is lightly collected.
