Ice maker and water purifier having the same

Abstract

There is provided an ice maker and a water purifier having the same capable of effectively making ice using two water trays. The water purifier having an ice maker includes a water tray member comprising an ice-making water tray holding ice-making raw water to make ice using an ice-making unit, and an auxiliary water tray holding ice-making raw water remaining in the ice-making water tray in the course of cooling the ice-making raw water by means of the ice-making unit and removing the ice-making raw water from the ice-making water tray; an ice reservoir storing ice made in the ice-making unit; a cold water storage tank cooling water held therein using the ice made in the ice-making unit; and a guide member guiding the ice made in the ice-making unit so that the ice is selectively fed to either the ice reservoir or the cold water storage tank. The ice maker and the water purifier having the came may be useful to improve the ice-making efficiency since residual cooling water cooled in the ice-making water tray is collected in the auxiliary water tray, and re-used to make ice.

1 . An ice maker comprising:
 an ice-making water tray holding ice-making raw water to make ice using an ice making unit; and   an auxiliary water tray holding ice-making raw water remaining in the ice-making water tray in the course of cooling the ice-making raw water by means of the ice-making unit and removing the ice-making raw water from the ice-making water tray.   
     
     
         2 . The ice maker of  claim 1 , wherein the auxiliary water tray is coupled to one side of the ice-making water tray. 
     
     
         3 . The ice maker of  claim 1 , wherein the auxiliary water tray is installed in one side of the ice-making water tray so that the auxiliary water tray is fixed and maintained in the ice-making water tray. 
     
     
         4 . The ice maker of  claim 1 , wherein the ice-making raw water remaining in the ice-making water tray is transferred to the auxiliary water tray as the ice-making water tray rotates toward an ice separation position by means of a water tray rotating means, and
 the residual raw water transferred to the auxiliary water tray is fed back to the ice-making water tray as the ice-making water tray returns to an ice-making position by means of the water tray rotating means.   
     
     
         5 . The ice maker of  claim 4 , wherein a rotation angle of the ice-making water tray rotated by the water tray rotating means is in a range of 80 to 120 degrees when the ice-making water tray moves from the ice-making position to the ice separation position. 
     
     
         6 . The ice maker of  claim 1 , further comprising a guide grill provided with a water inlet having a smaller diameter than that of the ice so that the ice-making raw water remaining in the ice-making water tray flows in the auxiliary water tray, the guide grill being mounted on the auxiliary water tray. 
     
     
         7 . The ice maker of  claim 6 , wherein the ice-making water tray and the auxiliary water tray rotate toward an ice separation position by means of the water tray rotating means, and
 the guide grill is inclined downwards along a direction where the ice falls down at the ice separation position.   
     
     
         8 . The ice maker of  claim 1 , wherein the ice-making unit comprises an evaporator installed to be immersed in ice-making raw water held in the ice-making water tray. 
     
     
         9 . A water purifier having an ice maker comprising:
 a water tray member comprising an ice-making water tray holding ice-making raw water to make ice using an ice-making unit, and an auxiliary water tray holding ice-making raw water remaining in the ice-making water tray in the course of cooling the ice-making raw water by means of the ice-making unit and removing the ice-making raw water from the ice-making water tray;   an ice reservoir storing ice made in the ice-making unit;   a cold water storage tank cooling water held therein using the ice made in the ice-making unit; and   a guide member guiding the ice made in the ice-making unit so that the ice is selectively fed to either the ice reservoir or the cold water storage tank.   
     
     
         10 . The water purifier of  claim 9 , wherein the ice-making raw water remaining in the ice-making water tray is transferred to the auxiliary water tray as the ice-making water tray rotates toward an ice separation position by means of a water tray rotating means, and
 the residual raw water transferred to the auxiliary water tray is fed back to the ice-making water tray as the ice making water tray returns to an ice making position by means of the water tray rotating means.   
     
     
         11 . The water purifier of  claim 9 , wherein the water tray member further comprises a guide grill provided with a water inlet having a smaller diameter than that of the ice so that the ice-making raw water remaining in the ice-making water tray flows the auxiliary water tray, the guide grill being mounted on the auxiliary water tray. 
     
     
         12 . The water purifier of  claim 11 , wherein the guide grill is inclined downward to the ice reservoir or the cold water storage tank at the ice separation position. 
     
     
         13 . The water purifier of  claim 9 , wherein the guide member rotates between a first position to which the ice is guided so that the ice is fed to the ice reservoir and a second position to which the cold water is guided so that the ice is fed to the cold water storage tank. 
     
     
         14 . The water purifier of  claim 9 , further comprising a controller controlling an amount of ice being fed to the cold water storage tank according to the temperature of water in the cold water storage tank.
