An ice-making water purifier includes a water tank unit, an instantaneous heating device, an extraction member, an ice-maker, a supply pump, an ice-making water inlet passage, an ice-making water supply valve, a flow rate sensor, and a controller configured to control driving of the supply pump and the opening and closing of the ice-making water supply valve such that purified water corresponding to a predetermined supply amount of ice-making water is supplied to the ice-maker on the basis of a flow rate value measured by the flow rate sensor. The controller controls the opening and closing of the channel such that purified water is preferentially supplied to the instantaneous heating device among the instantaneous heating device and the ice-maker.

An ice-tray for ice-making machines is formed by modular fabricated cups that can assembled together within a frame to create an ice-tray of arbitrary dimensions allowing a sharing of components among a variety of ice-tray sizes. Individual cups may include ice formation sensors or heaters or may be heated by an induction heating system.

An icemaking appliance includes an ice storage chamber and a water jacket at least partially surrounding the ice storage chamber. A sensor assembly includes a sleeve, a conductive plug inserted into a first portion of the sleeve, and a temperature sensor inserted into a second portion of the sleeve. The first portion of the sleeve and the conductive plug are at least partially disposed within the ice storage chamber.

This ice making machine includes an ice making unit that includes an ice making surface and a cryogen flow channel through which a cryogen for cooling the ice making surface flows; a pump that pressurizes and discharges the cryogen cooled by a heat exchanger; and a control unit that controls a discharge amount of the pump. The cryogen is carbon dioxide, and the control unit controls the pump such that the cryogen is in a gas-liquid mixed state at an outlet of the cryogen flow channel.

A domestic refrigeration appliance includes a refrigerator compartment set to a first target temperature by a regulation or control unit, an ice maker compartment being separated from the refrigerator compartment by an inner insulation layer and set to a second target temperature by the regulation or control unit and an ice maker in the ice maker compartment. The regulation or control unit can switch between a normal ice making mode and a reduced-power ice making mode in which the target temperature in the ice maker compartment lies between the target temperature in the refrigerator compartment and the target temperature in the ice maker compartment in the normal ice making mode.

In a refrigerator, a cam of a cam gear rotating by a driving motor is provided with a structure protruding from an edge portion of a cam gear to a center, thereby increasing the thickness of a cam surface. Therefore, it is possible to reduce the magnitude of force directly transferred from the cam gear to a magnet lever.

The invention relates to an ice dispensing system comprising an ice hopper, an ice chute for transporting ice from the ice hopper to a dispensing outlet or a waste outlet, an ice dispensing element for dispensing ice from the hopper into the ice chute, an ice directing element having a first position for directing ice to the waste outlet and a second position for directing ice to the dispensing outlet, and a controller for controlling the ice dispensing element and the position of the ice directing element. Also provided is a beverage dispensing machine comprising the ice dispensing system of the invention and a method for dispensing ice from the ice dispensing system or beverage dispensing machine of the invention.

An example of a system for touchlessly dispensing ice into a receptacle includes a dispense chute configured to direct dispensed ice therethrough to a dispense area. A visual feedback device is configured to present a visual indication of an operational status of the system. A sensor is configured to produce a beam within the dispense area and to provide a signal indicative of a proximity of an object within the beam to the sensor. A controller is configured to receive the signal and to determine the proximity of the object to the sensor from the signal. The controller is configured to operate the system to initiate a dispense of ice through the dispense chute based upon the determined proximity of the object. The controller is configured to operate the visual feedback device to present a visual indication of the initiated ice dispense.

In a refrigerator, a cam of a cam gear rotating by a driving motor is provided with a structure protruding from an edge portion of a cam gear to a center, thereby increasing the thickness of a cam surface. Therefore, it is possible to reduce the magnitude of force directly transferred from the cam gear to a magnet lever.

In an ice maker, a controller is operatively connected to the ice maker's water system to determine a parameter indicative of a total amount of water filtered by a replaceable filter cartridge. Based on the determined parameter, the controller can provide a numerical indication of the total amount of water filtered by the replaceable filter cartridge. Based on the determined parameter, the controller can determine that the replaceable filter cartridge requires replacement. The parameter can be determined based on the amount of time a water inlet valve is opened and/or a water pressure signal. The controller can take action when it determines that the water filter needs replacement, for example, by making a local alarm indication, pushing a remote notification, or making an automated purchase transaction for a new filter cartridge.
