Abstract: A protective device of an auger type ice making machine capable of coping with occurrence of a problem with a simple configuration. A protective device comprises a delay timer which starts counting simultaneously with the start of an auger motor. A compressor is started by the count up of the delay timer so as to start the ice making operation. At the same time, the energization to a shock relay is started, and a current-voltage converter contained therein detects a change in the current from the auger motor and converts into a voltage change followed by outputting. If no overload is applied on the auger motor and if the output voltage from the current-voltage converter is not an overload output voltage according to the overload current of the motor, steady operation continues without change. In contrast, if the output voltage from the current-voltage converter is an overload output voltage, the operation of the auger motor and compressor is stopped.

Abstract: Multiple ice making is determined according to a time needed for an ice making step or a change in time in which a refrigerant temperature drops.An ice making machine alternately repeats an ice making step of cooling ice making plates 10 and 10 where an evaporation pipe 14 connected to a refrigeration system 12 by circulatively supplying a refrigerant to the evaporation pipe 14, and producing lumps of ice M by circulatively supplying ice making water in an ice-making-water tank 22, and a deicing step of separating the lumps of ice M produced at the ice making plates 10 and 10.

Abstract: When refrigerant shortage has occurred, a failsafe operation, for example, for stopping an ice-making operation is carried out to thereby suppress wasteful electric power consumption and prevent an ice-making section and a compressor from being damaged. An ice-making machine alternately and repeatedly carries out the ice-making operation for producing ice blocks (M) by cooling an ice-making section (10) on which is disposed an evaporator (14) connected to a refrigeration system (12), by supplying refrigerant to the evaporator (14) for circulation, and deicing the operation for causing the ice blocks (M) produced on the ice-making section (10) to be released therefrom. During the ice-making operation, when time in which the outlet temperature of refrigerant from the evaporator (14) takes to reach a first preset temperature K1, after the start of the ice-making operation, is longer than a normal time tn1 in which the outlet temperature of the refrigerant from the evaporator (14) takes to reach the preset temperature K1 the abnormal state of shortage of refrigerant is determined and a failsafe operation is carried out.

Abstract: A water cooler having a container with a reservoir for storing water has a thermoelectric module operable to cool a conductor plate and form ice in the reservoir. A temperature sensor connected to the plate senses the temperature of the plate and activates a timer when the temperature is below the temperature at which water freezes. The timer operates a selected period of time to allow a block of ice to be formed on the plate. A photoelectric sensor operable to sense a selected size of the block of ice functions to actuate a switching device that changes the polarity of the electric power supplied to the thermoelectric module to supply heat energy to the plate to release the block of ice from the plate. The released block of ice floats in the water in the reservoir and cools the water.

Abstract: An ice-maker for use in a freezer compartment and a process of making clear ice cubes are disclosed. The ice-maker includes an ice-forming tray supported on a carrier body. The carrier body has a housing with an air-circulating fan directing a flow of air toward the tray during the ice-making process. The apparatus also includes means for moving the ice-forming tray during the ice-making process, to allow gases to escape so that substantially clear ice cubes are formed. In the process of the invention, the ice-maker is placed in the freezer compartment of a refrigerator. An ice-forming tray is placed on the carrier body. Cold air from the freezer compartment is blown across the tray during the ice-making process. The ice-forming tray is moved during the ice-making process to allow entrapped gases in the water to escape. With or without the air-circulating fan, the apparatus and process may cause the carrier body to move in at least two different axis. The apparatus and process may be fully automatic, with an automatic ice cube harvesting cycle in which the ice-forming tray is twisted to release the ice cubes from the tray and rotated through a predetermined arc to drop the ice cubes out of the tray.

Abstract: An auger-type ice making machine has a refrigerating cylinder having upper and lower bearings, an auger supported rotatably within the refrigerating cylinder by the upper and lower bearings, a water supply valve for supplying water to the refrigerating cylinder, a drain valve in fluid communication with the refrigerating cylinder for discharging water therefrom, an electric detector assembly including an electrode member having its one end extending into the refrigerating cylinder, and an electric control circuit electrically connected to the electrode member to receive a detection signal from the electric detector assembly. The electric control circuit determines on the basis of the detection signal that the impurity concentration of the water has increased beyond a predetermined level. The water supply valve and the drain valve are electrically connected to the control circuit to be closed and opened, respectively, when the control circuit determines that the impurity concentration of water has increased beyond this predetermined level, thereby interrupting the water supply to the refrigerating cylinder while discharging water therefrom in an automatic manner.

Abstract: A method operates a household refrigerator that has an ice maker that produces and/or dispenses ice in an ice production mode. The household refrigerator can at least partially deactivate a sub-process of the ice production mode in dependence upon a user-defined deactivation criterion. A first operating process is provided which when executed generates a first noise emission that is lower than that of the sub-process. A user-specific quiet time interval of the ice maker is provided as a deactivation criterion. At least the at least one sub-process of the ice production mode is deactivated at least partially during the quiet time interval. The operation of the household refrigerator is coordinated such that the first operating process is executed at least temporarily during the quiet time interval.
