Abstract: PROBLEM TO BE SOLVED: To provide a refrigerator in which clear ice blocks having reduced cloudiness can be produced through a simple arrangement. SOLUTION: The refrigerator comprises an ice making pan 14 disposed in an ice making chamber 2, a driver 15 having an output shaft 17 for turning the ice making pan 14 by a specified angle to discharge ice blocks therefrom, and a controller 26 for controlling rotation of the drive source of the driver 15, i.e. a stepping motor 16. While sustaining the temperature in the ice making chamber 2 in the range of -7 deg.C through -3 deg.C, the ice making pan 14 is shaken by the driver 15 until water supplied to the ice making pan 14 is changed to ice. When the ice blocks are separated from the ice making pan 14, the ice making pan 14 is twisted for 10 sec or longer at a twisting angle in the range of 10 deg.-30 deg..

Abstract: PROBLEM TO BE SOLVED: To stop and hold an icemaking tray at an origin position without locking a gear by constituting to hold a switch operated by a switch operating cam on a cam gear for rotating the tray in a section for maintaining an OFF signal when the tray is disposed at the origin position becoming horizontal. SOLUTION: In a driver for rotating a cam gear for rotating an icemaking tray by a drive gear engaged with the cam gear to rotate the tray and releasing an ice at an ice releasing position, a switch operating cam 121a is formed on a lower surface of the cam gear, and a switch 119 is closed by the cam 121a through a switch lever 120. A protrusion for changing an output signal of the switch 119 from an ON signal to an OFF signal, maintaining the Off signal and again changing to the ON signal is formed at the cam 121a. When the tray is disposed at an origin position becoming horizontal, the switch 119 is operated and held in a section for maintaining the OFF signal of the protrusion by the protrusion.

Abstract: PROBLEM TO BE SOLVED: To eliminate a state of uncertainty that an ice detection signal is generated or not generated according to the excess or deficiency of ice in a process of returning an ice making tray after release of the ice, without controlling an ice detecting lever, and further to simplify a structure. SOLUTION: Construction is so made that a switch 119 is made to output an Hi signal continuously by a first switch operating means during the time when an ice making tray is at -20 deg. to +30 deg. to the position of the origin as a reference at the time when ice in a prescribed quantity or more is present in an ice storage box and that the switch 119 is made to output the Hi signal continuously by first and second switch operating means during the time when the ice making tray is at -20 deg. to +84 deg. at the time when the ice in the prescribed quantity or more is not present in the ice storage box. By this construction, a switch signal is inverted by the same number of times invariably irrespective of excess or deficiency of the ice in a process wherein the ice making tray returns, without controlling an ice detecting lever. By using as a reference the position where the signal is inverted, therefore, the position of the origin can be detected without fail.

Abstract: PURPOSE:To improve the water proofness of a terminal portion, reliability of electric contact, etc., by fixing a water-proof type connector used at an electric connection part to a stopper and making up an electric contact member separately from a piston operation regulating member. CONSTITUTION:A water-proof connector 32 having electric connection terminal portions 33 of a terminal member 34 at an opening portion is fixed to a stopper 31. Moreover, a pair of contact members 37 which have resilience and are fixed to the end of a terminal member 34 and come into contact with the periphery of a spacer 28 are installed opposed to each other. When the pressure of a hydraulic line increases to more than a set pressure, the hydraulic pressure led in from the pressure lead-in hole of the case 21 installed at the hydraulic line moves a piston 25 resisting the power of a bias spring 30 and makes the conductive portion 26 of the spacer 28 come into contact with the pair of contact members 37. Thereby, an electric current flows to one of the electric connection terminal portions 33, the terminal member 34, one of the contact members 37, the conductive portion 26, the other of the contact members 37, the terminal member 34 and the other of the electric connection terminal portions 33 in that order to electrically turn the switch on.

Abstract: PROBLEM TO BE SOLVED: To provide a selector valve for a water-supply path having a structure, in which water leakage does not happen from a sealed discharge port, in relation to the valve for supplying water to a plurality of water-making trays for an automatic ice maker of a refrigerator. SOLUTION: Referring to the direction (indicated by an arrow) of the shortest distance to a space 1f of the main body having a flow from discharge port 1c through contact faces of an arc face 2a, an upper face 2b, a lower face 2c and a sealing face 2d of the body 1 of the valve 2, the direction is orthogonal or nearly orthogonal to the direction of the water flowing in the space 1f. The lateral pressure acts in the direction vertically approaching the current, so water does not flow in the direction of a discharge port 1d, and leakage can be positively prevented.
