Temperature-adjustable tumbler

Abstract

Provided is a tumbler capable of controlling a temperature of an accommodated drink. The tumbler includes an inner cup for accommodating a drink, a frame which protects the inner cup, a heat conduction unit of which heat is exchanged with the inner cup through a lower surface and an outer circumferential surface of the inner cup to cool or heat the drink of the inner cup, and a control unit configured to control operation of the heat conduction unit. The thermal efficiency and ease of use of the tumbler are improved due to the configuration of the tumbler.

         16 . The temperature controllable tumbler of  claim 15 , wherein the heat conduction unit further comprises a cooling unit configured to cool the second heat conduction unit disposed at one side thereof. 
     
     
         17 . The temperature controllable tumbler of  claim 15 , wherein thermal grease or a thermal pad that mediates heat conduction between the inner cup and the first heat conduction unit is interposed between the inner cup and the first heat conduction unit. 
     
     
         18 . The temperature controllable tumbler of  claim 17 , wherein a grease groove for accommodating the thermal grease is disposed in the outer circumferential surface of the inner cup. 
     
     
         19 . The temperature controllable tumbler of  claim 15 , wherein the frame comprises:
 an upper frame coupled to the upper edge of the inner cup and supporting the inner cup; and   a lower frame coupled to a lower end of the upper frame and having a space, wherein the second heat conduction unit is disposed inside of the space of the lower frame.   
     
     
         20 . The temperature controllable tumbler of  claim 19 , further comprising a support holder disposed around an outer side of the first heat conduction unit,
 wherein the support holder supports the first heat conduction unit and is coupled to and disposed inside the upper frame to maintain a state in which the first heat conduction unit is in contact with the lower surface or the at least a part of the outer circumferential surface of the inner cup.   
     
     
         21 . The temperature controllable tumbler of  claim 20 , wherein an empty space sealed to thermally insulate the inner cup or the first heat conduction unit from an outside is disposed between the support holder and the upper frame. 
     
     
         22 . The temperature controllable tumbler of  claim 21 , further comprising a Peltier holder holding the Peltier element part seated thereon and disposed under the support holder,
 wherein a state in which at least a part of the one side surface of the Peltier element part is in contact with the first heat conduction unit is maintained and a position of the Peltier element part is fixed.   
     
     
         23 . The temperature controllable tumbler of  claim 22 , wherein:
 the heat conduction unit further comprises a cooling unit configured to cool the second heat conduction unit disposed at one side thereof;   the cooling unit is disposed inside the lower frame; and   a first ventilation opening is disposed in the lower frame and air flows by the cooling unit through the first ventilation opening.   
     
     
         24 . The temperature controllable tumbler of  claim 17 , wherein the control unit comprises:
 an input part receiving a set temperature for the drink from the user;   an output part outputting a current temperature of the drink accommodated in the inner cup or the set temperature input through the input part for the user to recognize; and   a control part controlling the operation of the heat conduction unit so that a temperature of the drink becomes the set temperature input through the input part.
