Abstract: A water dispenser includes a slide table arranged in a lower portion thereof. The slide table includes a cup portion in which a piercing rod of a water supply line is provided, a container supporting portion configured to support from below a shoulder portion of a raw water container which is a transparent and deformable container, and a holder portion configured to guide downwardly s side peripheral portion of the raw water container. Since the surface color of the piercing rod is different from the surface color of the cup portion and the container supporting portion, it is possible to visually confirm how much the raw water container is pierced by the piercing rod.

Abstract: A water dispenser includes a pump which can lift water in an exchangeable raw water container into a water storage tank in a casing. The water dispenser further includes a water level sensor in the form of a float sensor for detecting the upper limit and the lower limit of the water level in the water storage tank. The water dispenser further includes a controller adapted to activate the pump upon receiving a sensor input indicative of detection of the lower limit, and deactivate the pump upon receiving sensor input indicative of detection of the upper limit. The controller is further adapted to measure the time elapsed since the pump was activated, and deactivate the pump when the time elapsed reaches a predetermined time at which the water level exceeds the upper limit and at which water in the water storage tank has not yet overflown the water storage tank.

Abstract: A water dispenser includes a raw water container which can be slid into and out of a loading space, while being placed on a slide table. The slide table has a container holder adapted to restrain the peripheral side wall of the raw water container. The minimum height and the shape of the container holder are determined such that when the peripheral side wall of the raw water container is collapsed, the raw water container is never pulled up by the container holder as a result of the peripheral side wall getting caught on the container holder, and such that when the raw water container becomes empty, the raw water container is received within the container holder. This prevents portions of the peripheral side wall from protruding into spaces behind front distal ends of side plates defining the loading space.

Abstract: A water dispenser is proposed of which a raw water container is mounted upside down at the lower portion of a housing. The water dispenser has a piercing member which serves both as one end of a water supply line and one end of an air intake line. With this arrangement, when the raw water container is opened, the interior of the raw water container is simultaneously connected to the water supply line and the air intake line. Raw water containers can be easily exchanged. The raw water container is made of a soft material, so that air can be freely sucked into the raw water container through the air intake line while a pump is activated. This allows the pump to lift water with a minimum force.

Abstract: A water dispenser includes a baffle which interferes with the downward flow of water introduced into a cold water tank through a water supply line. The baffle has a water transfer passage formed by a downwardly recessed surface portion formed on the top surface of the baffle and having a distal edge, and an edge portion having a predetermined thickness and located over the distal edge so as to overlap the distal edge. The water transfer passage is configured such that the recessed surface portion deflects the flow of water flowing down through the water transfer passage in a horizontal direction or a direction close to a horizontal direction. Water is thus discharged from the terminal end opening defined by the distal edge and the edge portion into the lower portion of the cold water tank in a direction close to a horizontal direction.

Abstract: A water dispenser includes a drawer having a rear side provided in the lower portion of a casing and is guided by guiding portions fixed to the casing. Before the casing which stands on a floor surface topples down and before the drawer comes into contact with a floor surface, casters support the front side of the drawer. Normally, axles of the casters are supported on respective front side support portions such that the casters roll on a floor surface. The casters collide against a step, so that the axles are moved to rear side support portions which are located higher than the front side support portions.

Abstract: The following water dispenser is provided. A circulation path is constituted by a water receiving container configured to receive drinking water flowing from the raw water container, a raw water supply line through which drinking water received in the water receiving container is supplied to a cold water tank by a pump, and first and second return pipes through which drinking water flowing in the raw water supply line returns to the water receiving container. The first return pipe is connected to the second return pipe through a hot water tank, and heated water is supplied to the circulation path from the hot water tank so as to sterilize the water receiving container, etc. at a high temperature.

Abstract: A water dispenser includes discharge valves each including a body made of a material capable of transmitting ultraviolet light, and defining a flow path extending from the inlet to the outlet of the discharge valves, and an ultra violet light emitting source which irradiates ultraviolet light to the body to sterilize inner wall surface of the flow path and the surface of the valve body. The body has an outer wall surface extending along the flow path and covered with an ultraviolet light reflecting layer. The water dispenser further includes and outlet-side pipe line having an inner wall surface made of an ultraviolet light transmitting material containing a photocatalyst.

Abstract: A water dispenser is provided which a first water level sensor configured to detect the water level in a cold water tank a second water level sensor configured to detect the water level in a buffer tank, an atmosphere communication line mounted to the cold water tank such that the interior of the cold water tank is maintained at atmospheric pressure, an air passage pipe through which the air layer in the cold tank communicates with the air layer in the buffer tank, and an abnormality water level sensor configured to detect that the water level in the cold tank has reached an abnormal level.

Abstract: A water dispenser is provided in which a when turned on, timer control of a sterilization operation is automatically started. If an initial input of a predetermined signal by a user is confirmed, after the sterilization operation, an energy saving operation in which the heater is maintained off for a limited time; and a reservation control in which reserved times determined by the timer control are updated based on the time when the input is made; are carried out. If a second or subsequent input is confirmed, the elapsed time since the last sterilization operation until the second or subsequent input is compared with a threshold. If the elapsed time is longer than the threshold, the sterilization operation, the energy saving operation, and the reservation control are carried out. If not, the energy saving operation is carried out without performing the sterilization operation and the reservation control.
