摘要： PURPOSE:To eliminate the space for an ice making means in a freezing chamber or a refrigerator chamber and to substantially shorten the working time for a repairing or maintenance service for the ice making means, CONSTITUTION:A water supplying bottle 4 is mounted at an inner plate of a door of a refrigerator chamber in a vertical orientation at a fixing side of a hinge 8, an automatic ice making device 1 comprising an ice making pan 2 or a driving device 3 is arranged at an upper right corner part, and an ice storing box 5 is arranged at a lower part of the ice making pan 2. Water in the water supplying bottle 4 is supplied to the ice making pan 2 by a water supplying pump through a water supplying pipe and when the door is closed, icing is formed by cold air got from a cold air suction port. When ice is formed at the ice making pan 2, the ice making pan 2 is twisted by a driving device 3, thereby the ice is peeled from the ice making pan 2, drops into the ice storing box 5 and the ice is stored in it. Accordingly, the shelf area of the freezing chamber or the refrigerator chamber is expanded, a mere removal of components elements at the door side enables the repairing service to be easily carried out and then its operation time can be substantially shortened.
