Cold-water generating apparatus and water purifier comprising same

A water purifier, comprising:

• a filtering unit for filtering raw water to generate purified water;
• and
• a cold water generating unit for generating cold water by receiving the purified water from the filtering unit,
• wherein the cold water generating unit comprises a flow path member through which a fluid flows, a block member which surrounds an outer circumferential surface of the flow path member to thermally contact the flow path member, and a cooling member which is provided with a thermoelectric module that is disposed on one side of the block member to cool the block member,
• wherein the block member comprises a plurality of zones that are thermally separated from each other,
• wherein the flow path member comprises first to n-th cooling passages that are respectively disposed in the plurality of zones, an inlet which is formed at one end of each of the cooling passages and exposed to outside of the block member, an outlet which is formed at the other end of each of the cooling passages and exposed to outside of the block member, and a connection pipe which connects the outlet of the k-th cooling passage and the inlet of the k+1th cooling passage,
• wherein the block member comprises a plurality of unit blocks in which the zones are respectively formed and a first separation space in which each unit block is disposed to be spaced apart from each other by a predetermined distance,
• wherein in the cooling member, the thermoelectric module is disposed to overlap the first to n-th cooling passages arranged in each of the above unit blocks,
• n is an integer of 2 or more, and
• k is an integer of 1 or more and less than or equal to n−1.
