A top surface has an inner and outer perimeter, with the inner perimeter defining the opening of the cavity. The lower chamber includes an upper deck portion and container structure depending therefrom. The upper chamber includes a top wall and an inner container structure depending from the top wall. The upper and lower chambers are positioned in sealing engagement.

A refrigerator includes a cabinet defining a storage space, a door configured to open and close at least a portion of the storage space, and an evaporator configured to generate cold air. The refrigerator also includes a first ice maker provided in the door, a second ice maker provided in the storage space and configured to be covered by the door when the door is closed, a first cold air guide configured to guide the cold air to the first ice maker, and a second cold air guide configured to guide the cold air to the second ice maker.

An instant freezer apparatus able to freeze consumable fluids and food having a freezing point lower than water is disclosed. The method of the present invention is directed to freezing of a substance such as to instantly freeze consumable fluids and food without altering their chemical compositions. The instant freezer apparatus generally comprises a main frame and a removable freezing module. The apparatus may further comprise a freezing fluid injection system such as a liquid carbon dioxide tank or a liquid nitrogen tank fluidly connected to the main frame. At least two freezing cells comprising the fluid to be frozen may be included, the freezing cells being independently removable from the freezing module and other freezing cells. A semi-flexible mat for receiving and supporting varying shapes of freezing cells may be included.

An ice maker for freezing water into ice pieces, the ice maker including an elongated cage having a central revolving axis about which the elongated cage revolves. The elongated cage having a first end, a second end and at least one elongated slot extending between the first end and the second end. An ice tray is configured to be received in the at least one elongated slot. The ice tray includes a plurality of cavities for receiving water to be frozen into ice pieces. A motor is coupled to the elongated cage for revolving the elongated cage about the central revolving axis. A controller is connected to the motor for controlling the revolving of the elongated cage about the central revolving axis.

The present invention relates to an ice making apparatus comprising a casing, ice trays, an ice receptacle, a retainer for rotatably supporting the ice trays and one or more than one knob for respectively twisting the ice trays either simultaneously or singly. In the ice making apparatus of the present invention, the retainer selectively supports either one of a plurality of exchangeable covers enabling a single or simultaneous twist type ice making apparatus. One exchangeable cover has a plurality of bearings.

A manual ice maker and a refrigerator comprising the same are provided. The manual ice maker comprises: an ice making body being a frame formed with an opening, and provided with a first positioning hole in a front wall thereof, a second positioning hole in a rear wall thereof and a first limiting protrusion on an inner surface of the rear wall thereof; an ice making tray provided with a first shaft at a front end thereof and a second shaft at a rear end thereof, the first shaft rotatably supported in and extended out of the first positioning hole, the second shaft rotatably supported in the second positioning hole; and an ice removing assembly. The ice removing assembly comprises: a twisting member provided with a gear; and a press member movable between a first position and a second position in a vertical direction to drive the gear to rotate.

An icemaking system includes a circulation circuit configured to circulate icemaking solution, at least one icemaker provided in the circulation circuit, a cooling mechanism, a first detector and an adjuster. The icemaker includes a cooling chamber and a scraping mechanism. The cooling chamber has an inflow port and an exhaust port of solution, and the cooling chamber allows the solution to flow in the cooling chamber. The scraping mechanism scrapes ice generated on an inner surface of the cooling chamber. The cooling mechanism cools the solution in the cooling chamber. The first detector detects whether the inflow port of the cooling chamber has an ice nucleus. The adjuster adjusts a cooling temperature of the solution in accordance with a detection result of the first detector.
