る。2. Description of the Related Art Generally, an automatic ice making device is known in which ice made in an ice making section is automatically stored in an ice storage container. In such an automatic ice making device, it is necessary to maintain a stable ice storage amount so that the ice in the ice storage container does not overflow from the ice storage container.

ような機能を具備した自動製氷装置が知られている。Therefore, conventionally, in such an automatic ice making device, an automatic ice making device having a function of detecting the amount of ice stored in an ice storage container, for example, as shown in Japanese Utility Model Publication No. 3-93379. The device is known.

る。This automatic ice making device allows the light emitted from the light emitting element to pass through the inside of the ice storage container, and detects whether or not the light receiving element can receive this light on the opposite side of the ice storage container to detect the ice storage. The amount of ice storage in the container is detected. That is, when the ice storage amount in the ice storage container is small, the light from the light emitting element passes through the ice storage container and is received by the light receiving element, so that the ice storage in the ice storage container is continued. Further, when the amount of ice storage in the ice storage container is large, the light from the light emitting element is blocked by the ice in the ice storage container and does not reach the light receiving element, so that the ice storage in the ice storage container is stopped.

なくなるといった不都合を生じる。However, in the above-mentioned conventional automatic ice making device, since the light-emitting surface and the light-receiving surface are simply provided with the uneven suppression wall portions, it seems that the freezer compartment door is opened for a long time. In this case, a sufficient effect cannot be obtained, and frost and dew condensation will occur on the suppression wall portion. As a result, the light emission and the light reception are not properly performed, and it becomes impossible to reliably detect the ice storage amount.
