Coupling structure for stack-on type automatic ice making machine

摘要

A stack-on type automatic ice making machine includes an ice making unit having a box-like casing housing an ice making mechanism, and a stocker within which a space opening upwardly is defined and on which the ice making unit is disposed. A coupling structure for connecting together the ice making unit and the stocker includes a plurality of ribs formed integrally with an external wall of the stocker along a top edge thereof, and a plurality of coupling plates secured fixedly to an external wall of the casing of the ice making unit and each having a hole for receiving each of the ribs and a resilient tongue adapted to engage in a recess formed in a bottom of each rib. The ribs are imparted with strength sufficiently high for withstanding shearing and bending loads. The ice making unit connected to the stocker through the coupling plates fitted on the ribs is positively prevented from displacement relative to the stocker. The resilient tongues of the coupling plates engage in the grooves formed in the bottoms of the ribs suppress resiliently relative movement between the ice making unit and the stocker.
