Abstract: A blower cover assembly of a dishwasher includes an attaching cap contacting a door liner, a guide sleeve extending frontward from the attaching cap, and a guide rib formed on an inner circumference to guide flow of washing water.

Abstract: A dishwasher and door locking device is provided. In the dishwasher, a tub forms a washing chamber, a door opens and closes a front of the tub, a latch lock has a tub insertion portion inserted in an upper edge of the tub and a latch lock ring formed at a front of the tub insertion portion with a hole having a predetermined size, a latch includes a latch holder and a latch link pivotably connected to a lower end of the latch holder, a latch body is fixed in the door to accommodate the latch, and at least one detection switch is attached to the latch body to detect opening and closing of the door. The latch holder is inserted in the door and formed with a notched portion at a front for coupling with the latch lock.

Abstract: A water guide for guiding the flow of water in a dishwasher via a sump maintains a precise level of water in the sump by directly measures an actual water level of the sump. The water guide includes a supply channel for supplying washing water to the sump; and a sensor configuration, installed along the supply channel, for sensing a water level of washing water contained in the sump.

Abstract: An objective lens of an optical pickup device for both CD and DVD, in which a short-wave pass (SWP) filter is inserted in the objective lens, is capable of allowing the optical pickup device to have a light-weight, slim, simple, and miniaturized structure. The objective lens is divided into two lens portions with respect to a direction transverse to a beam transmitting path and provided with a short-wave pass (SWP) filter. The lens portions have planarized divisional surfaces facing each other, respectively. The objective lens reduces the space occupied by the SWP filter. Accordingly, the objective lens of the present invention alleviates a restriction in the design of an optical system caused thereby and an increased margin is secured.

Abstract: Disclosed is a short-wave pass filter-inserted objective lens of an optical pickup device for both CD and DVD, in which a short-wave pass (SWP) filter is inserted in the objective lens, thereby being capable of allowing the optical pickup device to have a light-weight, slim, simple, and miniaturized structure. The objective lens is characterized in that it is divided into two lens portions in a transverse direction to a beam transmitting path and provided with a short-wave pass (SWP) filter, the lens portions having planarized divisional surfaces facing each other, respectively. The objective lens reduces the space occupied by the SWP filter. Accordingly, the objective lens of the present invention alleviates a restriction in the design of an optical system caused thereby. Also, there is an advantage in that an increased margin is secured.
