Abstract: A mattress assembly includes: an air pocket unit configured to contain air; a pressure regulator for controlling the air pocket unit; and a body unit accommodating the air pocket unit and the pressure regulator. The body unit includes: a frame part having a top side open to provide an accommodation space for accommodating the air pocket unit and the pressure regulator; and a cover part disposed on the frame part to cover the accommodation space. The cover part includes; a first area formed to be relatively movable with respect to the frame part and covering or exposing the pressure regulator; and a second area disposed adjacent to the first area and fixed to the frame part. The first area faces an upper edge of the frame part when covering the pressure regulator.

Abstract: A mattress assembly includes an air pocket, a flow channel, pumps for making air flow into the air pocket, a valve that regulates the air flow in the flow channel and air pocket, and a controller for controlling the pump and the valve so that the hardness of the air pocket changes. The flow channel includes first and second injection flow path members that provide passages for making the air flow from first and second pumps to a first and second air pockets, respectively, and an air flow path which communicates with the first and second injection flow path members. The valve includes a flow path valve for opening and closing the air flow path, and the controller controls the pump and the flow path valve so that the hardness of at least one of the first air pocket or the second air pocket changes.

Abstract: The present disclosure provides a water purifier including: a main body having a purified water outlet through which purified water is dispensed, a cold water outlet through which cold water is dispensed, and a hot water outlet through which hot water is dispensed; a first flow path module coupled to be attachable to and detachable from the main body and having a purified water dispensing pipe connected to the purified water outlet and a cold water dispensing pipe connected to the cold water outlet; and a second flow path module coupled to be attachable to and detachable from the main body and having a hot water dispensing pipe connected to the hot water outlet, wherein, when an external force of a predetermined value or more is applied in a first direction, coupling of the first and second flow path modules to the main body is fixed, and when the external force of the predetermined value or more is applied in a second direction, the coupling of the first and second flow path modules to the main body is relea

Abstract: The present disclosure relates to a water purifier. The water purifier according to the present disclosure includes: a tank providing an accommodation space, which extends in an up-down direction to accommodate purified water generated by filtering raw water and of which the maximum length in a height direction is at least three times the maximum length in a width direction or more, and provided so that the purified water is introduced through an upper side of the accommodation space; a cold water generator configured to cool the purified water accommodated in the accommodation space and generate cold water; a cold water dispensing flow path provided to dispense the cold water generated in the accommodation space to the outside; and an upper clamp assembly, an intermediate clamp assembly, and a lower clamp assembly provided to effectively respond to pressure that acts on the tank in the up-down direction.

Abstract: A cold water tank for a direct water purifier is provided.

Abstract: The present disclosure relates to a bidet that forms a pollution-preventing water film that prevents contamination of a cleaning nozzle, and the bidet according to the present disclosure includes a main body mounted at an upper side of a toilet bowl, wherein a ceramic ware containing an excrement of a user is formed in the toilet bowl; a toilet seat provided to the main body and forming a seating surface on which the user sits; a cleaning nozzle coupled to the main body and spraying cleaning water to wash the user's body; a pollution prevention module provided to the main body and including an outlet for discharging pollution-preventing water to prevent contamination of the cleaning nozzle; and a controller configured to control an operation of the pollution prevention module, wherein the outlet of the pollution prevention module discharges the pollution-preventing water to a front surface of the cleaning nozzle so that a surface of the main body is opened at a position spaced upward from the cleaning nozzle,

Abstract: An ice storage includes a storage body having a storage space for storing ice and a discharge port for discharging ice to the outside, a transferring and breaking part which, by having at least a part thereof provided in the storage space, transfers the ice in the storage space to the discharge port, and if necessary, breaks the transferred ice, and a door part allowing the ice to be discharged through the discharge port as unbroken ice or broken ice unbroken or broken up by the transferring and breaking part. The transferring and breaking part includes a transferring member for transferring ice and a breaking member for breaking ice, and the transferring member and the breaking member are configured such that ice is not stuck therebetween while being transferred.
