  • Patent number: 10415866
    Abstract: In an ice maker with a tray having at least one water-receiving cavity, a wall of the cavity contains a phase change material. If an ice maker of this kind is pre-cooled, so that the phase change material is solid, a great deal of heat can be removed from water poured into the cavities in a short time by the heat causing the phase change material to melt.

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. When the ice making step at which the time needed from the start of the ice making step to the end thereof becomes shorter than a normal ice making time is consecutively detected by a predetermined number of times, it is decided that multiple ice making has occurred and the ice making machine is stopped.

  • Patent number: 6988373
    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.

  • Patent number: 6951113
    Abstract: The icemaker presented here may use a microcontroller, and solid state refrigeration and heat transfer elements to create ice cube qualities ranging from “clear ice” to “fast ice” in a smooth, user selectable continuum. In one embodiment, this may be accomplished by fitting a standard, high production volume icemaker mold with (1) thermoelectric coolers operated in a controlled fashion to heat or cool the mold, (2) a mold temperature sensor (such as a thermistor), and (3) a microcontroller to monitor the process and to adjust the growth rate of ice forming in the mold by adjusting heat transfer rates to optimize particular cooling phases.

  • Patent number: 6766650
    Abstract: A method of controlling semi-frozen liquid beverage in a dispensing machine having a bowl to contain the beverage, a motor to turn a helical auger blade within the bowl to scrape the semi-frozen beverage, and a compressor to cool the beverage. The method includes the steps of actuating the compressor to the bowl until the temperature of the beverage is cool to reach an initial set point. The compressor is deactivated after temperature of the beverage is cooled at or below a set point. Torque on the motor caused by resistance to the auger blade is sensed after a defined time period following switching off of the compressor. The compressor is activated if the torque on the motor is below a certain level and the temperature set point is lowered from the initial set point to a lower set point in order to cool the product.

  • Patent number: 6339930
    Abstract: The present invention provides an improved system and method for sensing of ice, particularly applicable in the control of ice thickness in automatic ice-making machines. The ice-making machine may be of the conventional type using a cold plate with water flowing over it. A thermistor bead temperature sensor is encapsulated in a metal housing, which is in turn mounted on a carrier. The position of the carrier is adjustable relative to the cold plate. The control system has several variable delays or time durations which optimize system performance: 1. Minimum harvest time delay, relative to the start of the ice-making cycle; 2. Threshold persistence time delay, requires that the signal sensor persists above the harvest threshold value for a certain amount of time (referenced to when the threshold is first exceeded), before harvesting may begin; 3. Harvesting delay is an optional delay provided give the option of making sure the ice is sufficiently “cured.

  • Patent number: RE37696
    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.
