Abstract: A water purifier includes: a filter module for providing purified water by filtering raw water; a fitting valve module detachably fastened to the filter module to provide at least one of a flow path for a flow of raw water supplied to the filter module and a flow path for a flow of the purified water discharged from the filter module; and a frame including a valve support for movably supporting the fitting valve module to be movable. The fitting valve module is selectively placed in a separated state in which the fitting valve module is separated from the filter module by moving in a direction away from the filter module, or a coupled state in which the fitting valve module coupled to the filter module by moving toward the filter module.

Abstract: The present invention relates to a running-water-type evaporator, and an ice-making device and a water purification device comprising the same, and to a running-water-type evaporator, and an ice-making device and a water purification device comprising the same, the evaporator uniformly transferring, to ice, heat supplied through high-temperature fluid during ice separation, so as to enable the ice to be easily separated without using separate ice-separating water, and thus minimizes melting of the ice during ice separation, and circulating ice-making water in a state where the ice-making water flows only toward the outer sides of a pair of outer plate members, and thus a degradation in the cleanliness of the ice-making water can be prevented.

Abstract: The present invention relates to a cold-water generating apparatus and a water purifier comprising same, in which: by arranging a block member to surround the outer circumferential surface of a flow path member through which fluid flows, and cooling the block member so that the fluid is cooled, thereby sufficiently lowering the temperature at which the fluid is cooled; and by arranging cooling passages respectively in a plurality of zones provided in the block member and thermally separated from one another, providing a connection pipe to allow the fluid to sequentially flow through the cooling passages, and preventing heat exchange from occurring between the fluid introduced through the connection pipe and the fluid discharged therefrom, the maximum amount of cold water can be secured, thereby improving user satisfaction.

Abstract: A hot water generation apparatus and a water purifier including the same includes: a collection space inside a case member that is disposed above a receiving space in which raw water is accommodated, and has an inclination surface having a predetermined angle of inclination, and a steam outlet through which steam can be discharged is disposed above the collection space, separately from a hot water outlet, so that steam is removed in advance through the steam outlet along the inclination surface before hot water is discharged to the outside. Therefore, since hot water free of steam is discharged and a regular flow of hot water is formed in a straight line along the direction of gravity, user safety is enhanced, aesthetics are improved, and the best user experience can be provided.

Abstract: The tube-shaped pleated filter member may comprise: a filter body having a tube shape such that a filter medium is pleated and is wound; and a support unit. The filter body may comprise outer pleated portions corresponding to the outside of the tube shape, and inner pleated portions corresponding to the inside of the tube shape. An inner virtual line connecting corners of the inner pleated portions may have the shape in which a unit wave shape recessed in the outward direction is repeated. Assuming, that the thickness at a part having the maximum distance between the inner virtual line and the outer virtual line is a first thickness (T1), the first thickness (T1) may have a range defined by [equation 1] with regard to the diameter (D) of the outer virtual line. D/15?T1?D/6.

Abstract: The present invention relates to an air purifier in which vertical rotation and horizontal rotation are performed simultaneously and independently and which has a stable structure.

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.
