Ice making machine for use in refrigerator

Abstract

The invention relates to an ice maker for refrigerator or cold storage device, comprising a control module, which can drive the rotating ice ejector move the ice body out of the mould of ice maker more stably. The control module is coupled with the driver of ice ejector, which comprises a gear and a shaft part of ice ejector. The gear and the shaft of ice ejector, which are made of hard plastic material, especially the polyamide resin, transform high torque to the rotating ice ejector without damage phenomenon of plastic driver parts. In a practical example, the driving sleeve tube on the gear is connected with the driving shaft part with a spline so that the driven force in driving clutch is allocated more effectively. In another practical example, metal pipe is tightly mated on the sleeve tube of gear so as to improve the torque transmission in the driving clutch. Although manufacturing tolerance or the force in loading, traveling or installing of ice maker make the imperceptibility change full of contact at the horizontal installing position, the control module can be full of the mold of ice maker according to the presetting standard in operation furthermore in each cycling period.

Description

technical field [0001] The present invention relates to an ice maker, in particular to an improved driving control module for an ice maker applied to a refrigerator or similar devices. Background technique [0002] Ice makers are well known for use in refrigerators or freezers, for example, US Pat. No. 5,261,248 discloses an ice maker comprising a mold in which water freezes to form cubes or other shaped ice cubes, rotatable An ice ejector having a plurality of radial ice ejection arms. A drive module, configured to rotate the ejector shaft, includes a drive motor that drives the periphery of a gear having an axial sleeve that houses and drives a vertical camshaft whose rotation during the ejection cycle Rotate the ejector in sequence while controlling the rotation of the contact arm on the ice surface. [0003] During the ejection cycle, ice cubes can sometimes become lodged between the ejector arm and the stripper, preventing or interrupting rotation of the ejector. In ...

AI Technical Summary

Problems solved by technology

Furthermore, once the contact position is correctly determined, the shipping and handling of the icemaker, and subsequent installation in a refrigerator or freezer, may change the radial position of the contacts, thus causing unwanted changes during water refilling

Additionally, since the contact adjustment screw protrudes from the unit, it may interfere with packaging and is susceptible to chipping or breakage during handling of the ice machine

Thus, heretofore, the adjustable positioning of the water refill contact relative to the gear contact rail was intended to enable an accurate filling standard within the mold, but also resulted in some uncertainties and water fill cycle problems in the art.
