Cold-water making apparatus and water purifier comprising same

An apparatus for making cold water, comprising:

• a case member in which storage water is accommodated;
• a water inlet flow path member for providing a flow path of incoming water which flows into the case member;
• a water outlet flow path member for providing a flow path of outflowing water which flows out from an inside of the case member;
• and
• a cooling member which is disposed on one side of the case member to cool the storage water which is accommodated inside the case member,
• wherein the case member is provided with an upper wall and a lower wall which are disposed to be opposite to each other along a height direction, a pair of side walls which are disposed to be opposite to each other along a width direction, a heat transfer wall and an opposite wall which are disposed to be opposite to each other along a depth direction, diaphragms which are disposed to be parallel to the width direction so as to divide the inside of the case member into a plurality of zones, a water inlet port, which is in communication with the water inlet flow path member such that the incoming water flows in, and a water outlet port, which is in communication with the water outlet flow path member such that the outflowing water flows out,
• wherein the upper wall, the lower wall and the pair of side walls are integrally formed with the heat transfer wall,
• wherein in the heat transfer wall, the diaphragms are formed to integrally extend such that the storage water directly contacts an inner surface of the heat transfer wall in the process of flowing between the diaphragms,
• wherein the opposite wall is coupled such that the inside of the case member is closed,
• wherein an inclined surface which extends upward in a direction toward the opposite wall along the depth direction is formed on an inner surface of the upper wall,
• wherein an inclined surface which extends downward in a direction toward the opposite wall along the depth direction is formed on an inner surface of the lower wall, and
• wherein any one of the water inlet port and the water outlet port is disposed adjacent to the heat transfer wall along the depth direction such that the storage water inside the case member flows while directly contacting the inner surface of the heat transfer wall, and the other port is disposed adjacent to the opposite wall.
