A washing machine having a drying function including: a tub; a drum inside the tub; a heat exchanger above the tub for heating air supplied into the tub; an air blowing fan to guide air through a circulating flow path passing through the tub and the heat exchanger, a filter case disposed on one side of the main body; and a filter module coupleable to and decouplable from the filter case. The filter module may include: a filter mesh; and a cleaning member which sweeps the filter mesh to separate foreign substances caught in the filter mesh as the filter module is decoupled from the filter case.

A metallic flat gasket with at least one metallic layer and at least one filter element. The at least one metallic layer has at least one passage opening, which is covered by the filter element. The filter element has a mesh material.

Disclosed is an anti-leakage liquid storage device for electronic cigarette, including a cylindrical liquid storage cup, at least two locking members arranged at an inner wall of a liquid outlet end of the liquid storage cup, a liquid percolation piece having a plurality of liquid percolation holes and having a circular edge which engages with an internal circumferential surface of the liquid outlet end of the liquid storage cup, and a filter piece with one side thereof abutting against the liquid percolation piece; wherein the other side of the filter piece abuts against an annular pressing plate, the annular pressing plate has a circular edge which engages with the internal circumferential surface of the liquid outlet end; the annular pressing plate is locked by the at least two locking members and tightly presses the filter piece and the liquid percolation piece.

First protuberance of a squared-U-shaped frame in one case and second protuberance of a squared-U-shaped frame in other case contact each other, and the one case and the other case are joined together through a method such as vibration welding and/or the like. Furthermore, a gasket is positioned at a position contacting the end of the first protuberance and the end of the second protuberance, and also positioned so as to surround an intake opening, and is jointed to a flank in the one case and a flank in the other case.

An air cleaner includes a case, an air inlet, an air outlet, a grill covering the air inlet to filter airborne oil droplets, a fan to suction air through the air inlet and discharge air out of the air outlet, a roll filter provided between the grill and the fan to filter oil mist, and a filter roller to cut the roll filter. The roll filter includes a roller and a filter sheet wound around the roller, and the filter sheet may be unwound to extend behind the grill. When the filter sheet becomes dirty, the roll filter is further unwound so that a clean section is provided behind the grill, and the filter cutter may cut off the dirty section. During cutting, a clamp holds down the filter sheet. The case includes a slit through which the dirty section of the filter sheet passes for discarding.
