A refrigerator of the present disclosure includes a tray configured to form an ice making cell, a water supply valve configured to control the flow of water to the ice making cell, and a controller configured to control the water supply valve, in which the controller controls the water supply valve to turn off the water supply valve to stop water supply while performing water supply and turns on the water supply valve again for additional water supply after the water supply valve is turned off.

The present invention relates to a refrigerator. A refrigerator according to the present invention may comprises a first tray assembly forming one part of ice-making cells, and a second tray assembly forming the other part of same. Following the start of ice making process, so that ice can be produced in the direction of ice-making cells formed by any one tray assembly, from among the first and second tray assemblies, to the ice-making cells formed by the other tray assembly, the other tray assembly comprises a first surface forming a part of the ice-making cells, and a second surface extending from the first surface and supported by at least one surface of the one assembly.

Provided is a refrigerator. The refrigerator may include a first tray assembly defining a portion of an ice making cell and a second tray assembly defining another portion of the ice making cell. The one tray assembly of the first and second tray assemblies may include a first portion that defines at least a portion of the ice making cell and a second portion extending from a predetermined point of the first portion.

A refrigerator according to the present disclosure includes a tray configured to form an ice making cell, a cooler configured to supply cold air to the ice making cell, a water supply valve configured to control the flow of water to the ice making cell, and a controller configured to control the water supply valve, wherein the controller controls the water supply valve so that cold air from the cooler is supplied to the ice making cell before the water supply valve is turned on, and water is supplied to the ice making cell after the cold air is supplied to the ice making cell.

A refrigerator according to the present invention includes a storage chamber configured to store food, a cold air supply part configured to supply cold air to the storage chamber, a tray configured to form an ice making cell being a space in which water is phase-changed into ice by the cold air, a temperature sensor configured to sense the temperature of water or ice in the ice making cell, a heater configured to provide heat to the tray, and a controller configured to control the heater, in which the controller controls the heater to be turned on so that ice can be easily separated from the tray when the ice making is completed, and the controller controls the heater to be turned off when a temperature sensed by the temperature sensor reaches a first turn-off reference temperature greater than zero after a first reference time elapses in a state in which the heater is turned on.

The refrigerator of the present invention comprises: a storage compartment where food is stored; a cold air supply means for supplying cold air to the storage compartment; a first tray forming a part of an ice making cell which is a space where water phase-changes into ice by the cold air; a second tray which forms another part of the ice making cell and which can be brought into contact with the first tray during an ice making process, and which is connected to a driving unit so as to be spaced apart from the first tray during an ice separating process; a heater positioned adjacent to at least one of the first tray and the second tray; an ice bin for storing ice dropped from the ice making cell; a full ice level sensing means for sensing a full ice level of the ice bin; and a control unit for controlling the heater and the driving unit.

When the full ice level of the ice bin is sensed by the full ice level sensing means, the control unit controls the driving unit such that the second tray moves to the ice separating position after the ice making is completed.

A refrigerator according to the present disclosure includes a first tray configured to form a portion of each of a plurality of ice making cells, and a second tray configured to be rotatable with respect to the first tray and to form the other portion of each of the plurality of ice making cells, in which water supply is performed at the water supply position of the second tray, when water supply is completed, the second tray is moved to the ice making position, and one or more of the first tray and the second tray is provided with a communication hole for communicating the plurality of ice making cells at the ice making position of the second tray.

An icemaker appliance includes a container defining a liquid reservoir, an ice mold selectively received within a portion of the liquid reservoir, a temperature sensor provided within the liquid reservoir and configured to monitor a temperature of the liquid, a water level sensor provided within the liquid reservoir and configured to determine a level of the liquid within the container, and a controller attached to the container, the controller being operably connected with the temperature sensor and the water level sensor, the controller including a wireless communication module configured to wirelessly communicate with a remote terminal.

An ozone generator for producing ozone water for the sanitation and disinfection of an ice maker includes cathode plates and anode plates that are arranged alternatively in an electrolysis chamber. The cathode plates and the anode plates are connected to a cathode wire and an anode wire of a cable. A wiring chamber is provided with a temperature sensor extending into the electrolysis chamber and connected with a temperature sensor wire of the cable. The cable is connected to a control circuit. The ozone generator is submerged in the ice-making water of the ice-making water tank. The temperature sensor of the ozone generator submerged in the ice-making water is configured to sense temperature changes. When the ice maker is activated, the temperature of the ice-making water in the ice-making water tank will drop. When the temperature drops to the set temperature, the ozone generator is activated once to produce ozone gas. The ozone gas is dissolved in the ice-making water to generate ozone water. The ozone water is used to sanitize the ice-making loop process of the ice maker. The ozone generator has simple structure, low cost and good effect.
