Abstract

A water purifier includes: a hot water tank; an inlet pipe connected to the hot water tank and configured to supply purified water to the hot water tank; a heater for heating the hot water tank; an inverter comprising a printed circuit board for controlling the operation of the heater; a heat sink formed of a metal material, and disposed to partially enclose the inlet pipe; and a power semiconductor element electrically connected to the printed circuit board of the inverter to control power to the heater, and fixed to the heat sink to heat-exchange with purified water flowing in the inlet pipe. The heat sink includes: a first heat discharge member having a first accommodation part that corresponds to one outer periphery of the inlet pipe; and a second heat discharge member having a secondaccommodation part that corresponds to the other outer periphery of the inlet pipe, wherein the first and second accommodation parts are disposed to completely enclose the outer periphery of the inletpipe when the first and second heat discharge members are coupled to each other.

Description

technical field [0001] Embodiments relate to a water purifier equipped with a power semiconductor element to control power supplied to a heater for heating a hot water tank. Background technique [0002] According to whether a water tank is installed, the water purifier can be divided into a water storage tank type and a direct water type. The storage tank type water purifier is configured to store purified water in a water tank, and to supply the purified water stored in the tank when a user manipulates a discharge unit. In contrast, the direct water type water purifier does not have a water storage tank, and supplies purified water to a user by immediately filtering raw water when the user manipulates the discharge unit. Since the direct water type purifier is hygienic and can save water compared with the storage tank type water purifier, user's preference for the direct water type purifier has recently increased. [0003] In addition to normal temperature water, the wat...
