A water purifying apparatus comprises: a filtering unit; a water tank unit for storing water having passed through the filtering unit; an extraction unit for selectively extracting the water stored in the water tank unit; and a cleaning system for sequentially controlling a cleaning process and a rinsing process of the water tank unit. Since cleaning and rinsing processes for the water purifying apparatus are automatically executed by a series of consecutive processes, the user may directly clean the water purifying apparatus if necessary without requiring a Codi's visit. Furthermore, the number of times that the Codi visits the users home for cleaning of the water purifying apparatus is reduced. This may allow the Codi to have an enhanced working efficiency, and to pay less effort to a cleaning process for the water purifying apparatus.

Water purifying apparatus having cleaning system

A method for cleaning a water purifier comprising: a filtering unit; a water tank unit for storing purified water having passed through the filtering unit; and a discharging unit for discharging out the purified water stored in the water tank unit, the method comprises: a cleaning water supplying step of supplying cleaning water in which a cleaning agent is dissolved to the water tank unit; a cleaning water discharging step of discharging the cleaning water when a predetermined time has lapsed; a rinsing water supplying step of supplying rinsing water to the water tank unit when the cleaning water discharging step has been completed; and a rinsing water discharging step of discharging the rinsing water when a predetermined time has lapsed. In the method, cleaning and rinsing processes for a water purifier are automatically executed by a series of consecutive processes. Accordingly, a user can directly clean the water purifier if necessary without requiring a Codi's visit.

Method for cleaning water purifier

A water purifying apparatus, comprises: a filtering unit for filtering water supplied from a wellhead into purified water; a water tank unit including a cold water tank for storing the purified water in a cold water state, and a hot water tank for storing the purified water in a hot water state; a discharging unit for selectively discharging out the purified water stored in the water tank unit; a state detecting unit for detecting an operation state of at least one of the filtering unit, the water tank unit, and the discharging unit; a controller for comparing the information detected by the state detecting unit with a preset reference, thereby judging an abnormal state of the water purifying apparatus; and a state displaying unit for displaying the abnormal state information to outside. When the water purifying apparatus has a breakdown, mal-operated components of the water purifying apparatus may be checked by being displayed on the state displaying unit, without being checked by an A/S specialist. This may reduce the time taken to repair the mal-operated components, thereby enhancing a consumer's satisfaction degree for a service.

Water purifying apparatus

A food keeping refrigerator is provided. The food keeping refrigerator keeps food in refrigerating and freezing chambers and refrigerates and freezes the food through a cooling device. The food keeping refrigerator preserves the freshness and nutrition of food for an extended period of time by emitting appropriate light to the food stored in the refrigerating and freezing chambers of the food keeping refrigerator. The food keeping refrigerator includes a storing device that stores food keeping information, a light generating device mounted inside the refrigerating and freezing chambers that generates light and emits the light to the food, and a controller that reads the food keeping information corresponding to the food from the storing device and controls the light generating device to emit the light according to the food keeping information.
