Description

Bottom swing type transparent ice ice maker {TRANSPARENT ICE MAKER WITH SHAKING PLATE}

The present invention relates to a transparent ice ice maker, and more specifically, to a bottom swing type transparent ice ice maker that can easily produce compact and transparent ice by swinging the ice water in the ice maker around a rocking plate.

In general, an ice maker is a device that makes ice by cooling supplied ice-making water.

A conventional ice maker includes an ice maker main body and an ice making unit. The ice maker main body includes an ice storage unit for storing ice made in the ice making unit. The ice making unit consists of an ice maker, a cooling plate, and an evaporation tube, and an ice making plate. is filled with ice-making water, and a number of cooling protrusions immersed in ice-making water are installed on the lower surface of the cooling plate. The evaporation tube is installed on the upper surface of the cooling plate and is connected to the refrigeration system. Refrigerant flows into the evaporation tube, and the cooling plate and cooling protrusions are cooled by heat exchange of this refrigerant.

Recently, ice makers have been provided that can produce transparent ice by preventing cloudiness in the ice that occurs when bubbles in ice-making water freeze.

The white turbidity phenomenon that occurs in the ice during the ice making process is caused by the uneven ice making speed during the ice making process, in which the water surrounded by the ice formed earlier turns into ice and increases in volume, causing the previously formed ice structure to be destroyed, which occurs within the ice structure. The formed pores appear as a white turbidity.

In order to remove this white turbidity, the ice-making water in the ice-making dish must be shaken to remove voids or bubbles generated in the ice created during the ice-making process.

In order to generate oscillation in the ice-making water, as a conventional ice-making device, it is proposed that a rocking plate structurally having an L-shaped rocking plate is installed at the bottom of the ice-making plate. However, the prior art uses one end of the ice-making device to vibrate from the outside of the water plate. Since the applied and bent part becomes the axis, there was a complicated installation structure to implement it on the water dish, and there was a disadvantage of having a more complicated structure by implementing the detection structure for detecting ice in contact with the rocking plate on the water dish.

In addition, in order to generate fluctuation in the ice-making water, a conventional ice-making device has been proposed in which one side of the ice-making dish is extended and a biased axis point is formed in order to increase the shaking range of the ice-making dish.

However, in the above-described prior art, because one side of the ice making device is extended, the ice making plate becomes larger, and space is needed to rotate the ice making plate for ice removal, but there is a problem in that the ice making device as a whole becomes larger due to the larger ice making plate, As a result, the amount of ice-making water in the ice-making plate increases, causing a problem in that ice-making efficiency decreases.
