The refrigerator further includes a pusher having a first edge pressing the ice or at least one of the first and second tray assemblies to separate the ice from the tray assemblies, a bar extending from the first edge, and a second edge disposed at the end of the bar. The second tray assembly includes a first coupling part connected to the pusher and a second coupling part connected to the driver. The controller moves at least one of the pusher and the second tray assembly to change a relative position between the pusher and the second tray assembly.

Refrigerator

A refrigerator may include: a storage chamber, a first ice-maker, a second ice-maker, a cooler for supplying the cold to the storage chamber and the ice-making chamber, an ice bin for storing ice generated by the second ice-maker, a water supply unit for supplying water to the ice-making cell, a heater for supplying heat to the ice-making cell, and a controller for controlling the heater. The controller may increase the heating amount of the heater when the heat transfer amount between the cold in the storage chamber and the water in the ice-making cell is increased, and decreases the heating amount of the heater when the heat transfer amount between the cold in the storage chamber and the water in the ice-making cell is reduced.

A refrigerator may include a first tray assembly forming a part of an ice making cell, a second tray assembly forming another part of the ice making cell, a heater provided adjacent to at least one of the first or second tray assemblies, a driver connected to the second tray assembly, and a control unit to control the heater and the driver. The driving unit includes a cam capable of being connected to the second tray assembly, and a path in which a lever moves is formed inside the cam.

The refrigerator according to the present invention comprises: a storage compartment for storing food; a cooler for supplying cold to the storage compartment; a first tray assembly forming a part of ice-making cells which are where water changes phase to ice due to the cold; a second tray assembly forming the other part of the ice-making cells; a heater located adjacently to the first tray assembly and/or the second tray assembly; and a control unit for controlling the heater. Any one of the first and second tray assemblies has a greater degree of cold transfer than the other tray 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 first tray configured to form a portion of an ice making cell, a second tray configured to form another portion of the ice making cell, a tray temperature sensor configured to sense the temperature of the ice making cell, a discharge spark generator disposed around one of the first tray and the second tray and including an electrode, and a controller configured to control the discharge spark generator to generate a spark from the electrode when it is determined that the water in the ice making cell is supercooled based on the temperature measured by the tray temperature sensor.

Refrigerator and controlling method therefor

A refrigerator includes 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 refrigerator includes a pusher provided with a first edge on which a surface configured to press one or more of the first and second tray assemblies is disposed to easily separate the ice from the tray assemblies, a bar extending from the first edge, and a second edge disposed at an end of the bar. At least one of the pusher or the second tray assembly moves so as to change a relative position between the pusher and the second tray assembly.

The refrigerator according to the present invention may comprise: a first tray assembly forming a part of ice-making cells; and a second tray assembly forming the other part of the ice-making cells. In order that ice can be produced in the direction of ice-making cells formed by any one of the first and second tray assemblies to ice-making cells formed by the other tray assembly, following the start of an ice-making process, the one tray assembly comprises a first part, and the first part comprises: a first surface forming a part of the ice-making cells; and a first deformation-resistant reinforcement part extending from the first surface in the vertical direction away from a heater.

The present invention relates to a refrigerator. A refrigerator of the present invention may comprise: a first tray assembly forming a part of ice-making cells; a second tray assembly forming the other part of the ice-making cells; and a heater. In order to reduce the transfer heat, which is transferred from the heater to any one of the first and second tray assemblies, to ice-making cells formed by the other tray assembly, the one tray assembly may comprise a first part forming at least a part of the ice-making cells. The degree of heat transfer of the first part may vary along the outer circumferential surfaces of the ice-making cells.

A refrigerator according to the present invention may comprise a first tray assembly forming one part of ice-making cells, and a second tray assembly forming the other part of same. Any one tray assembly, from among the first and second tray assemblies, comprises a first part forming at least a part of the ice-making cells, and a second part extending from a set point on the first part so as to reduce water supplied to the ice-making cells from leaking through a space between the first and second tray assemblies.

Provided is a refrigerator in which a heater disposed at a side of a first tray or a second tray may be turned on in at least partial section while a cold air supply part supplies cold air to an ice making cell so that bubbles dissolved in water within the ice making cell move from a portion at which ice is made toward liquid water to make transparent ice, and one or more of the cooling power of the cold air supply part and the heating amount of heater may be controlled according to a mass per unit height of the water in the ice making cell so that the transparency is uniform for each unit height of the water in the ice making cell.

Refrigerator and method for controlling the same

A refrigerator includes: a storage chamber; a cooler to cool the storage chamber; a first tray assembly and a second tray assembly configured to define an ice making cell; a heater disposed adjacent to at least one of the first tray assembly or the second tray assembly; and a controller configured to control the heater, wherein the controller controls the heater to be turned on to make transparent ice from water within the ice making cell, and the controller controls the heater so that when a heat transfer amount between the storage chamber and the water of the ice making cell increases, the heating amount of the heater increases, and when the heat transfer amount between the storage chamber and the water of the ice making cell decreases, the heating amount of the heater decreases.

A refrigerator may include: a first tray forming a part of ice-making cells; a second tray forming the other part of the ice-making cells; a heater for supplying heat to the ice making cells; a cooler for supplying cold to a storage compartment; and a control unit for controlling the heater and the cooler. The operation modes of the refrigerator include a first mode and a second mode. The control unit may control so that either or both of the amounts of cooling by the cooler and the amount of heating by the heater vary in the first mode and the second mode.

A refrigerator includes a storage space, a cooler, a first tray constituting a part of a cell which is the space in which water is phase-changed to ice by the cold, a second tray, which constitutes another part of the cell, a water supply valve to adjust the flow of water to be supplied to the icing cell, a water supply amount detection unit or sensor, and a controller configured to control the supply valve.

The present invention relates to a refrigerator. A refrigerator of the present invention may comprise: a first tray assembly forming a part of an ice making cell; and a second tray assembly forming another part of the ice making cell.
