A refrigerator includes: a main body including a storage compartment; an inner door rotatably coupled to the main body; an outer door rotatably coupled to a front of the inner door; a dispenser provided in the inner door and configured to supply water; and a water supply device provided in the inner door, and configured to supply a predetermined amount of water to a container, the water supply device including a sensor configured to detect a level of the water in the container, wherein the outer door may include: a door body including a dispenser opening configured to expose the dispenser in a state in which the outer door at least partially covers the inner door; and a door panel detachably mounted on the door body.

A beverage apparatus, the beverage apparatus being hand-holdable by a user of the beverage apparatus to be portable, can include a beverage chamber housing that includes a chamber for storing a consumable liquid. The beverage apparatus can include a dispensing assembly that includes a receptacle. The receptacle can retain a vessel. The vessel can include an electronic tag and can contain an additive. The dispensing assembly can be operatively controllable by a controller to output the additive from the vessel into the consumable liquid. The beverage apparatus can include one or more sensors, devices, or assemblies that can be used to detect a volume of liquid in the chamber or a liquid level in the chamber. The beverage apparatus can include an apparatus computer processor portion (ACP) and an apparatus database portion.

Disclosed herein are a water purifying device and a method for controlling the same. The water purifying device is characterized in that a water discharge module capable of moving vertically is provided with a sensor. Specifically, in the water purifying device of one embodiment, the sensor may measure a height of a container, by transmitting and receiving a signal for measuring a distance at a first point of the water discharge module, and may detect both a height of the inlet of the container and a water level, by transmitting and receiving the signal and measuring a water level at a second point of the water discharge module.

Provided is a system (1) for autonomous filling of a container (5), comprising: a fluid dispenser (9); a distance (11); a plurality of electromagnetic radiation emitters (2) and receivers (3); a user interface (6) configured to receive a desired percentage of the height of the container (5) to be filled with liquid; and a controller electronically connected to the distance sensor (11), the plurality of emitters (2) and receivers (3), the user interface (6) and the fluid dispenser (9).

Disclosed are a water purifier and a control method thereof for controlling a main body by executing an artificial intelligence (AI) algorithm or a machine learning algorithm in a 5G environment established for the Internet of things. The control method of the water purifier according to the present disclosure includes a photographing step, a scanning step, a recognizing step, a calculating step, a determining step, and a water discharging step. When the water discharging step is initiated, the distance sensor generates real-time height information on the water surface, and may stop discharging water before a real-time height exceeds the highest point height.

A portable, self-contained beverage apparatus includes a container assembly having a known storage capacity for storing a consumable liquid, and a dispensing assembly disposed within the container assembly that dispenses variable, non-zero quantities of additives into the consumable liquid. The dispensing assembly includes multiple apertures structured and arranged to retain vessels containing the additives to be dispensed into the consumable liquid. The beverage apparatus also includes a level sensor disposed within the container assembly that determines a consumable liquid level of the consumable liquid stored in the container assembly. In certain embodiments, one or more positive displacement pumping mechanisms are configured to pump additive liquid from additive containers into a beverage chamber.
