Ice making device and control method for ice making device

Abstract

An ice making device may include an ice tray, a raking member disposed on an upper side of the ice tray for raking out ice pieces from the ice tray, a water-supply port disposed on a side of the ice tray for supplying water to the ice tray, and a drive control part for driving the raking member and for controlling supply of water from the water-supply port to the ice tray. The raking member is provided with a plurality of raking parts which are protruded sideward from the rotation shaft for raking out the ice pieces from the respective recessed parts for ice making, and the drive control part supplies water from the water-supply port to the ice tray at a time when the raking parts are located to be apart from the water-supply port. Preferably, the drive control part supplies water when the raking parts are located on an opposite side to the water-supply port with respect to the rotation shaft.

1 . An ice making device comprising:
 an ice tray;   a raking member which is disposed on an upper side of the ice tray for raking out ice pieces from the ice tray;   a water-supply port which is disposed on a side of the ice tray for supplying water to the ice tray; and   a drive control part for driving the raking member and controlling supply of water from the water-supply port to the ice tray;   wherein the ice tray is provided with a plurality of recessed parts for ice making;   wherein the raking member comprises;
 a rotation shaft which is rotationally driven around an axial line of the rotation shaft by the drive control part; and 
 a plurality of raking parts which are protruded sideward from the rotation shaft for raking out the ice pieces from the respective recessed parts for ice making; and 
   wherein the drive control part supplies water from the water-supply port to the ice tray at a time when the raking parts are located to be apart from the water-supply port.   
   
   
       2 . The ice making device according to  claim 1 , wherein the drive control part supplies water to the ice tray when the raking parts are located on an opposite side to the water-supply port with respect to the rotation shaft. 
   
   
       3 . The ice making device according to  claim 2 , wherein
 the drive control part comprises:
 a drive source; 
 a cam body which is rotationally driven by the drive source; and 
 a water-supply switch which is operated by a cam face of the cam body for supplying water to the ice tray; 
   the raking member is rotationally driven by the cam body; and   the cam face of the cam body is formed so that the water-supply switch is operated to supply water to the ice tray when the raking parts have reached to a position on the opposite side to the water-supply port with respect to the rotation shaft.   
   
   
       4 . A control method for an ice making device which include an ice tray, a raking member which is disposed on an upper side of the ice tray for raking out ice pieces from the ice tray, a water-supply port which is disposed on a side of the ice tray for supplying water to the ice tray, and a drive control part for driving the raking member and for controlling supply of water from the water-supply port to the ice tray, comprising:
 previously preparing the ice tray which is provided with a plurality of recessed parts for ice making;   previously preparing the raking member comprising;
 a rotation shaft which is rotationally driven around an axial line of the rotation shaft by the drive control part; and 
 a plurality of raking parts which are protruded sideward from the rotation shaft for raking out the ice pieces from the respective recessed parts for ice making; and 
   performing water-supply operation from the water-supply port to the ice tray by the drive control part after the raking parts have passed and apart from the water-supply port.   
   
   
       5 . The control method for an ice making device according to  claim 4 , wherein the drive control part supplies water to the ice tray after the raking parts have been moved on an opposite side to the water-supply port with respect to the rotation shaft. 
   
   
       6 . The control method for an ice making device according to  claim 5 , wherein the drive control part keeps the raking member to stop under a state that the raking parts are located on an opposite side to the water-supply port with respect to the rotation shaft until ice pieces in the ice tray have been manufactured. 
   
   
       7 . The control method for an ice making device according to  claim 6 , wherein
 the drive control part comprises:
 a drive source; 
 a cam body which is rotationally driven by the drive source; and 
 a water-supply switch which is operated by a cam face of the cam body for supplying water to the ice tray; 
   ice pieces are raked out from the ice tray by the raking parts of the raking member while the cam body is rotationally driven by the drive source by one turning;   the state that the raking parts are located on the opposite side to the water-supply port with respect to the rotation shaft is set to be in an initial state, and   the cam face for operating the water-supply switch is formed at an end position of the one turning.
