Abstract: A lens spacer may be configured to maintain a gap between a first lens and a second lens arranged along an optical axis. The lens spacer may include a first film member having a ring shape and may include a plurality of first tabs and a plurality of first recesses disposed between adjacent ones of the first tabs. The first tabs may protrude from an inner circumferential surface of the first film member toward the optical axis. A second film member may have a ring shape and may include a plurality of second tabs and a plurality of second recesses between adjacent ones of the second tabs. The second tabs may protrude from an inner circumferential surface of the second film member toward the optical axis. The first and second film members may be arranged along the optical axis, and the second tabs may overlap respective ones of the first recesses.

Abstract: A zoom lens barrel assembly includes a first barrel, a second barrel, a lens barrier, and a transparent member. The first barrel supports at least one lens. The second barrel surrounds at least a portion of an outer surface of the first barrel, and supports the first barrel to protrude along an optical axis direction. The lens barrier is disposed on a front side of the first barrel, and is moved in a direction that intersects an optical axis to expose the at least one lens when the first barrel is protruded. The transparent member is disposed on a front side of the lens barrier, and prevents impurities from entering the first barrel.

Abstract: Provided is a built-in cooking appliance including: a top plate; a main body under the top plate, the main body receiving at least a heater; a fan inducing an air flow in the main body; a cabinet including a receiving portion on which the top plate is mounted; and a top frame covering an airflow opening between at least one edge of the top plate and the cabinet, wherein the main body includes at least one edge adjacent to the airflow opening and supported by the cabinet. The built-in cooking appliance can efficiently discharge warm air and prevents an inflow of external water. In addition, convenience in cleaning the built-in cooking appliance can be improved, and operation reliability of the built-in cooking appliance can also be improved by the thermally-stable state in the cooking appliance.

Abstract: A built-in cooking appliance is provided. The built-in cooking appliance includes a body frame of a main body, a heating body, a top plate, a cabinet, a support in a contact space between the cabinet and the top plate, and a plurality of channels provided in the support. The top plate is disposed in an upper portion of the body frame to support a dishware to be heated. The cabinet supports the top plate. The plurality of holes are provided in the support to discharge air flowing out from the body frame. A size of each of the channels is small enough to prevent flow of water while allowing flow of air. Accordingly, cooling efficiency, safety and convenience of the built-in cooking appliance in using and cleaning it can be improved.

Abstract: A ventilation hooded microwave oven is provided. In the ventilation hooded microwave oven, a pull-up door is attached to a cavity assembly. The pull-up door is supported by a door support device when the pull-up door is pulled to open a cooking chamber of the ventilation hooded microwave oven. Therefore, a place where the ventilation hooded microwave oven is installed can be more efficiently used, and loading and unloading food into and out of the cooking chamber can be carried out more easily.

Abstract: A cooking system is provided. The cooking system includes: a radio frequency tag; a cooking appliance provided with a radio frequency reader to receive food related data from the radio frequency tag, the cooking appliance comprising at least a heating element; and a server receiving at least the food related data from the cooking appliance, the server transmitting food cooking data for cooking a food suitable for the cooking appliance using the food related data, wherein the cooking appliance operates using the food cooking data.

Abstract: The present invention relates to a oven and a method of controlling the same.
