Manufacturing method for ice making device and ice making device

Abstract

A manufacturing method for an ice making device which includes an ice tray, a heater for heating the ice tray, and a drive unit having a drive source for discharging ice pieces from the ice tray and is capable of supplying power to the heater, may include integrating the ice tray with the heater to previously manufacture an ice making unit, and then connecting the ice making unit with the drive unit to manufacture the ice making device. The ice making device in which assembling efficiency can be enhanced and sticking of fragments and dirt to an ice tray can be prevented is manufactured by the above-mentioned method.

       2 . The manufacturing method for an ice making device according to  claim 1 , further comprising:
 previously forming an engagement part for connection which is electrically connected to the heater in the ice tray; and   previously forming an engaged portion for connection in a case body of the drive unit which is capable of being fitted with the engagement part for connection of the ice tray;   wherein when the ice making unit is connected with the drive unit, the drive unit and the heater are electrically connected with each other at a fitting portion of the engagement part for connection of the ice tray and the engaged portion for connection of the case body of the drive unit.   
   
   
       3 . The manufacturing method for an ice making device according to  claim 2 , further comprising:
 previously forming a protruded terminal part having electrically insulating property which is provided with a terminal of the heater at a center portion of the terminal part in the engagement part for connection of the ice tray;   previously forming a recessed part as the engaged portion for connection which is opened to an outer side in the case body of the drive unit; and   previously disposing a connection terminal which is to be electrically connected to the terminal of the heater in the recessed part;   wherein the protruded terminal part having electrically insulating property is fitted into the recessed part of the case body to electrically connect the terminal of the heater to the connection terminal which is disposed in the recessed part of the case body.   
   
   
       4 . An ice making device comprising:
 an ice tray;   a heater for heating the ice tray; and   a drive unit having a drive source for discharging ice pieces from the ice tray and is capable of supplying power to the heater;   wherein the heater is integrated with the ice tray;   wherein an engagement part for connection which is electrically connected to the heater is formed in the ice tray;   wherein the drive unit include a case body which is provided with an engaged portion for connection which is capable of fitting with the engagement part for connection; and   wherein the drive unit and the heater are electrically connected with each other at a fitting portion of the engagement part for connection of the ice tray and the engaged portion for connection of the case body of the drive unit.   
   
   
       5 . The ice making device according to  claim 4 , further comprising
 an earth member which is disposed in the case body; and   a metal screw which electrically connects a portion where the earth member is disposed in the case body with the ice tray.   
   
   
       6 . The ice making device according to  claim 4 , further comprising
 a protruded terminal part having electrically insulating property which is provided with a terminal of the heater is formed at a center portion of the terminal part in the engagement part for connection of the ice tray;   a recessed part as the engaged portion for connection which is opened to an outer side in the case body of the drive unit; and   a connection terminal which is to be electrically connected to the terminal of the heater is disposed in the recessed part;   wherein the protruded terminal part having electrically insulating property is fitted into the recessed part of the case body to electrically connect the terminal of the heater to the connection terminal which is disposed in the recessed part of the case body.   
   
   
       7 . The ice making device according to  claim 6 , wherein
 two protruded terminal parts are formed on a side face part of the ice tray and a temperature detecting part for monitoring a temperature of the ice tray is formed at a portion between the two protruded terminal parts; and   the case body is formed with two recessed parts as the engaged portion for connection corresponding to the two protruded terminal parts of the ice tray, and a thermostat is provided between the two recessed parts of the case body; and   when the two protruded terminal parts of the ice tray are fitted into the two recessed parts of the case body, the thermostat is abutted with the temperature detecting part of the ice tray.   
   
   
       8 . The ice making device according to  claim 4 , further comprising a raking member for raking out ice pieces manufactured in the ice tray which structures an ice making unit together with the ice tray and the heater;
 wherein the ice tray and the heater of the ice making unit are fixed to the drive unit and the raking member of the ice making unit is connected with the drive unit so as to be capable of rotatably driven by the drive unit.
