Benefits of technology

The patent describes a way to easily assemble and adjust the position of an ice sensing shaft and its biasing member. This is done by using a stopper on a supporting member, which limits the movement of the ice sensing shaft in the second axis direction. This method prevents misalignment and facilitates the assembly of the ice sensing shaft and its biasing member. Overall, the technical effect of this patent is to simplify and optimize the assembly process of the ice sensing shaft and its biasing member.

Problems solved by technology

However, in the configuration described in Japanese Laid-open Publication No. 2001-165539, when the ice sensing shaft is assembled, since it is necessary to adjust a position of the ice sensing shaft in the axis direction and align the spring engaging part and the notch (compression coil spring), much time and effort is required.
In addition, misalignment is likely to occur between the spring engaging part of the ice sensing shaft and the compression coil spring, and in an extreme case, the ice sensing shaft is assembled in a state in which the spring engaging part restricts the end of the compression coil spring from above.

Embodiment Construction

[0017]An objective of an embodiment in the disclosure is to provide an ice making device that can appropriately and easily assemble an ice sensing shaft to a biasing member used for a drive unit.

[0018]In the disclosure, when the ice sensing shaft is assembled and the biasing member is elastically deformed, a position of the ice sensing shaft in the second axis direction is limited by the stopper of the supporting member. Therefore, since it is not necessary to align positions of the ice sensing shaft and the biasing member while a position of the ice sensing shaft in the second axis direction is adjusted, the ice sensing shaft can be assembled easily and efficiently. In addition, when the ice sensing shaft is assembled, since misalignment is unlikely to occur, the ice sensing shaft can be appropriately assembled with the biasing member.

[0019]In an aspect of the disclosure, the biasing member is a compression coil spring whose axis direction goes along a direction crossing the second...

Abstract

An ice making device is provided. In the ice making device, a drive unit includes an ice sensing shaft driven to rotate by a cam surface of a cam gear, a biasing member that biases the ice sensing shaft toward the cam surface, and a second case member. The second case member includes a stopper that comes in contact with the ice sensing shaft from one side of the ice sensing shaft in an axis and limits the ice sensing shaft in the axis direction when the ice sensing shaft is assembled and the biasing member is elastically deformed. When the ice sensing shaft positioned by the stopper is rotated around the axis, a spring engaging part passes through a notch of a side wall and compresses the biasing member.
