Abstract: A ventilated mattress for a bed minimizes the leakage of external air, having flowed in from the outside, through a portion other than ventilation holes, and thus has improved ventilation performance.

Abstract: A multi-functional storage system includes a storage compartment, a circulation flow path positioned at the rear of the storage compartment, and including an inlet end and an outlet end each communicating with the storage compartment, through which circulating air flows, and a flow path inlet for introducing the circulating air into the circulation flow path, the flow path inlet being positioned between the storage compartment and the circulation flow path and in communication with the inlet end of the circulation flow path.

Abstract: A fluid supplying apparatus includes an inner tube having a plurality of holes for distributing a fluid supplied from a supply unit, and an outer tube arranged coaxially or non-coaxially with the inner tube to surround the inner tube and having a plurality of slots for injecting the fluid distributed therein from the holes to the outside. The outer tube substantially has the same length as the inner tube. The fluid supplying apparatus may be used for a thin film cleaning system or method.

Abstract: A water purifier is provided.

Abstract: The filter head having a filter head main body includes: an inflow passage communicating with an inflow portion; an outflow passage communicating with an outflow portion; a filter introduction hole communicating with the inflow passage, to which an introduction portion of a filter is connected when the filter is mounted; a filter discharge hole communicating with the outflow passage, to which a discharge portion of the filter is connected when the filter is mounted; and a bypass flow channel connecting the inflow passage and the outflow passage and allowing the remaining flow of the fluid introduced through the inflow portion to pass therethrough so as to be expelled together with the fluid which has passed through the filter, through the outflow portion.

Abstract: A water purifier includes: a purified water tank storing purified water; a hot water tank connected to the purified water tank to receive the purified water from the purified water tank and including a heater heating the received purified water; a manipulation unit through which an extraction amount of hot water is inputted; and a control unit performing a control to supply the purified water of the purified water tank to the hot water tank by the extraction amount of hot water, when the extraction amount of hot water is inputted to the manipulation unit, and operating the heater to heat the water of the hot water tank. According to the present invention, the power consumption of the water purifier decreases in comparison with a conventional water purifier. Furthermore, it is possible to provide an accurate amount of hot water to a user without using a water level sensor.
