7 results about "Clear ice" patented technology

An ice making system and its associated method of making clear ice. A mold is provided that defines an interior cavity. An open neck leads into the interior cavity and provides a pathway for water to be added into the interior cavity. A coolant system is used to cool at least the lower part of the mold. Water is added to fill the interior cavity. An agitator is coupled to the mold. This causes the water in the interior cavity to wash over the forming ice as the water freezes within the mold. The agitator is controlled to prevent areas of slow water movement within the mold. Active cooling is maintained until ice fills the interior cavity of the mold and at least part of the open neck.

The invention relates to the technical field of ice makers, and provides an ice making control method and device for transparent ice and an ice maker. The ice making control method for the transparent ice comprises the following steps: starting water circulation, and enabling water in the cold water tank to circularly flow through the ice making grids; ice making is started, the ice cube tray is refrigerated, part of water flowing through the ice cube tray is frozen, and part of water flows back to the cold water tank; and obtaining water level change of the cold water tank, determining that the water level change reaches the target water level descending height, stopping ice making and entering an ice unloading program. Through the water level change of the cold water tank, it is determined that the water level change reaches the target water level descending height, ice making is stopped, and an ice unloading program is started, closed-loop control over the ice making machine is achieved, dependence on other devices of the ice making machine is avoided, the ice making quality is stable and controllable, and the service life is prolonged along with the increase of use time. The ice outlet quality is not affected under the condition that the refrigerating capacity is reduced due to compressor efficiency attenuation, refrigerant leakage, heat preservation performance degradation and the like, and the defect that the quality of ice cubes produced by an existing ice maker is unstable is overcome.

An ice maker includes an ice forming mold having a first mold surface defining a first cavity. A fluid conduit is configured to carry a cooling fluid for cooling the first mold surface. A water outlet is positioned and configured to stream water over the first mold surface. A heatable shaping mold includes a second mold surface defining a second cavity. One or both of the shaping mold and the ice forming mold are moveable relative to each other from an ice forming position, wherein the shaping mold is spaced apart from the ice forming mold, and a shaping position, wherein the shaping mold and the ice forming mold are abutted such that the second cavity of the shaping mold and the first cavity of the ice forming mold define an ice piece shape. A method of forming clear ice pieces is also provided.

The invention relates to the field of ice making, and provides an ice making method and ice making equipment. The ice making method comprises the steps that for an ice making assembly executing a first ice making mode, the temperature of the environment where the ice making assembly is located and the actual water temperature of a cold water tank of the ice making assembly are obtained in response to switching information of a second ice making mode; determining a theoretical water temperature interval of the cold water tank corresponding to the environment temperature in the second ice making mode; determining that the actual water temperature is not in the theoretical water temperature interval, and controlling and adjusting the ice-making duration in the second ice-making mode until the ice-making assembly reaches a stable working state in the second ice-making mode; wherein one of the first ice-making mode and the second ice-making mode is a transparent ice mode, and the other one of the first ice-making mode and the second ice-making mode is a static ice mode. When the modes are switched, the ice making duration of the ice making assembly is controlled and adjusted by judging the relation between the actual water temperature and the theoretical water temperature under the environment temperature, so that large ice or too small ice particles are avoided, the icing quality is improved, and the ice making assembly is protected to the maximum extent.

The invention relates to the field of ice making, and provides an ice making method and ice making equipment. The ice making method comprises the steps that for an ice making assembly executing a transparent ice mode, the temperature of the environment where the ice making assembly is located and the actual water temperature of a cold water tank of the ice making assembly are obtained in response to switching information of a static ice mode; the theoretical water temperature, corresponding to the environment temperature, of the cold water tank in the static ice mode is determined; and determining that the actual water temperature is lower than the theoretical water temperature, and shortening the ice making duration in the static ice mode until the ice making assembly reaches a stable working state in the static ice mode. According to the embodiment of the invention, when the transparent ice program is switched to the static ice mode, the ice making duration of the ice making assembly is controlled to be shortened by judging the relation between the actual water temperature and the theoretical water temperature under the environment temperature, so that large ice is avoided, the icing quality is improved, and the ice making assembly is protected to the maximum extent.
