Abstract

The invention discloses a water purifier with enhanced user convenience and a control method for the same. The water purifier comprises a filter unit filtering raw water to produce purified water, a tank storing the purified water, a water supplying pipeline arranged between the filter unit and the tank to supply purified water to the tank, a rotary plug distributing the purified water stored in the tank, a water distribution pipeline supplying the purified water in the tank to the rotary plug, a discharging flowpath distributing water from a distribution flowpath to the branch, and a check valve arranged on the discharging flowpath and opening to discharge air from the tank when pressure is lower than the water pressure of an external tap. Therefore, the water purifier can effectively prevent water splash and noise production due to air discharge of the rotary plug.

Description

technical field [0001] The present invention relates to a water purifier, and more particularly, to a water purifier with enhanced user convenience. Background technique [0002] In general, a drinking water supply device refers to a device for supplying drinking water to a user. Such potable water supply equipment may be a stand-alone equipment or form part of other equipment. [0003] For example, a water purifier is a device that purifies raw water supplied from an external water tap and supplies purified water to a user by filtering with a separate filtering means. In addition, a device that supplies purified cold or hot water to users as needed may also be called a water purifier. The water purifier is a device that is independent of other household appliances. [0004] Such a drinking water supply may form part of a domestic appliance such as a refrigerator. That is, water purified by the water purification device in the refrigerator may be supplied to the outside ...
