Embodiment Construction
[0051] Reference will now be made in detail to the preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings.
[0052] Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts. In the drawings, the size and shape of elements may be exaggerated or reduced for convenience and clarity of description.
[0053] Also, terms including ordinal numbers such as first and second are used in this specification to describe various elements. However, the elements are not limited by the terms, and the terms are only used to distinguish the elements.
[0054] In the following description, water to pass through the filter will be defined as raw water, raw water that has passed through the filter will be defined as clean water, and clean water containing minerals will be defined as mineral water. In addition, the rear end and the front end may mean the upstream side and the downstream sid...

The invention relates to a drinking water supply device. The drinking water supply device comprises a housing, which is used to form an appearance of a drinking water supply device; a water supply pipe, in which flows the clean water; a mineral water supply module, which comprises a mineral water supply pipe, a mineral material box used for storing predetermined amount of contracted minerals, a pump used for discharging minerals to the mineral supply pipe, and a mineral water generating unit connected with the water supply pipe and the mineral supply pipe; a discharging pipe, which is connected with the mineral water generating unit used for discharging the clean water or the mineral water; a mineral discharging sensor, which is used for sensing the discharging of the minerals; a controller, which is used to determine whether the mineral water supply module is abnormal according to the mineral sensed by the mineral discharging sensor, and is used to calculate the residual amount of the mineral stored in the mineral box based on the sensed discharged amount of the minerals; and a display unit, which is used to display the residual amount of the mineral according to the signal from the controller.
Description
[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2015-0000903 filed on Jan. 5, 2015, which is hereby incorporated by reference as if fully set forth herein. technical field [0003] The present invention relates to a drinking water supply device capable of supplying mineral water, and more particularly, to a drinking water supply device capable of displaying a mineral residual amount such that a user easily recognizes when a mineral cartridge should be replaced. Background technique [0004] Generally, a drinking water supply device is a device that supplies drinking water to a user. The drinking water supply device may be a stand-alone device, or may form part of an electronic household appliance such as a refrigerator. [0005] The drinking water supply device can supply room temperature drinking water to the user. In addition, the drinking water supply device may cool drinking water using a c...
