Ice making device, ice making refrigerator, ice making method

Abstract

Provided is a domestic refrigerator provided with an ice making device capable of eliminating defective ice, capable of dispensing with a mechanism for treating cloudy ice melting water, and capable of making ice of high transparency by inexpensive constitutive members, and to provide the device and a method reduced in energy for making easily the transparent ice. This ice making device is mounted with an ice making pan provided with a plurality of ice generating parts, in every ice making block of the single-structured ice making pan partitioned into the plurality of ice making blocks to store water and to make the ice.

Description

technical field [0001] The present invention relates to a technique for obtaining highly transparent ice by separating dissolved gas components and ion components in water supplied to an ice making tray when ice is produced in an ice making device. Background technique [0002] In the past, in household refrigerators, etc., as an automatic ice maker that has been popularized, water supplied from a water supply device is stored in an ice tray to make ice, and after ice is made, the drive device reverses the ice tray to make ice Leave to store on the ice. Generally, however, cloudy ice forms. [0003] Generally, where a substance forms a crystal, the crystal is formed from a single component. The same is true when water is frozen into ice. Therefore, impurities dissolved in water are discharged to the ice-water interface during the freezing process, and the impurities at the ice-water interface become a supersaturated state. When the growth rate of the ice is higher than th...

Problems solved by technology

In addition, when the ice is released, the thickness of the solid layer increases as a whole along the bottom surface of the pan, so that the torque when the ice is released increases, and there is a problem that not only the size of the motor is increased, but also excess energy is required.

In addition, after leaving the ice, in order to melt the ice on the lower tray, it is necessary to continuously power on for 30 to 60 minutes at a high input of about 10W, which may affect the ice in the water storage tank under the ice tray and other chambers, and deteriorate the power consumption. lead to impractical problems

In addition, a mechanism for returning the melted water to the water supply tank and a dehydration cage for scooping up the ice from the water to dry it are required, which complicates the structure, increases the size, and increases the manufacturing cost.
