Abstract: A leaf switch may include a cam body formed with a plurality of cam parts in a multistage shape and a plurality of leaf contact pieces which are extended toward the cam body and whose tip end sides of the plurality of leaf contact pieces are respectively abutted with the plurality of cam parts, and base end sides of the plurality of leaf contact pieces are held at the same height position. Further, an ice making device may include a water supply leaf switch for controlling water supply from a water-supply part to an ice tray, and a water supply amount adjust mechanism which includes an operation member that causes a leaf contact piece to deform to adjust a timing when the water supply switch is turned on or off. Further, an ice making device may include an ice detecting lever and a lever position detecting mechanism which detects ice amount in an ice storage part by detecting a position of the ice detecting lever.

Abstract: A torque limiter may include a first member provided with a circumferential face, a second member provided with a base plate part and a cylindrical drum part which is extended from the base plate part so as to surround the circumferential face of the first member, and an urging member for urging the cylindrical drum part of the second member to the circumferential face of the first member. The cylindrical drum part is formed with a plurality of cutout parts to be divided into a plurality of elastic plate parts. The cutout part is extended from a tip end of the cylindrical drum part to a middle position in a radial direction of the base plate part and the elastic plate part is formed of the cylindrical drum part and the base plate part.

Abstract: An ice making device may include an ice making unit having an ice tray and a heater; and a drive unit connected with the ice making unit. The drive unit may include a drive source, a cam body driven by the drive source, a leaf switch in which a leaf contact piece is displaced by a cam face of the cam body to perform “ON” or “OFF” operation, and a case body. The case body is provided with a first partition wall which partitions the inside of the case body into a first space and a second space, and the leaf switch and at least the cam face of the cam body is disposed in the second space. The first space may be preferably located on an ice making unit side and the first space is interposed between the second space and the ice making unit.

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.

Further, an ice making device may include a water supply leaf switch for controlling water supply from a water-supply part to an ice tray, and a water supply amount adjust mechanism which includes an operation member that causes a leaf contact piece to deform to adjust a timing when the water supply switch is turned on or off. Further, an ice making device may include an ice detecting lever and a lever position detecting mechanism which detects ice amount in an ice storage part by detecting a position of the ice detecting lever.

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.
