Refrigerator
A refrigerator comprises: a storage chamber for storing food; a cold air supply means; a first tray forming one part of an ice making cell; a second tray forming the other part of the ice making cell and connected to a driving unit so as to come into contact with the first tray during an ice making process and be separated from the first tray in an ice separating process; a heater positioned adjacent to the first tray and/or the second tray; an operation unit for inputting a start command of a test mode; and a control unit for controlling the heater and/or the driving unit in the test mode, wherein, if the start command of the test mode is input during the operation of the heater, the control unit turns the heater off and operates the driving unit such that the second tray moves.
1 . An ice maker comprising:
a tray including a first portion and a second portion, the first portion and the second portion being configured to define a cell that is a space formed to receive a liquid; and
an ice separation heater configured to supply heat to the cell,
wherein the second portion moves relative to the first portion between:
a first position where the first portion contacts the second portion to form the space and the liquid in the space is phase-changed into ice, and
a second position where the first portion and the second portion are spaced apart from each other; and
wherein, when a start command of a test mode is input during an operation of the ice separation heater, the ice separation heater is configured to be turned off.
2 . The ice maker of claim 1 , wherein, when the start command of the test mode is input, the second portion moves in a first direction.
3 . The ice maker of claim 1 , wherein, after the ice separation heater is turned off, the second portion moves in a first direction.
4 . The ice maker of claim 2 , wherein the second portion moves toward the second position.
5 . The ice maker of claim 4 , wherein, the second position is an ice separation position, the ice is separated from the tray while the second portion moves toward the second position.
6 . The ice maker of claim 4 , wherein the second position is a liquid supply position, the liquid being supplied to the space when the second portion is in the liquid supply position.
7 . The ice maker of claim 1 , further comprising a first tray case coupled to the first portion of the tray.
8 . The ice maker of claim 7 , wherein the first tray case is manufactured as a separate part from a bracket and then is coupled to the bracket, a component of the ice maker being provided inside or outside the bracket.
9 . The ice maker of claim 7 , wherein the first tray case is integrally formed with a bracket, a component of the ice maker being provided inside or outside the bracket.
10 . The ice maker of claim 7 , wherein the first tray case is manufactured as a separate part from a bracket and then is coupled to the bracket, or is integrally formed with the bracket, each component of the ice maker being provided inside or outside the bracket.
11 . The ice maker of claim 7 , further comprising a first heater case in which the ice separation heater is installed, and the first heater case is integrally formed with the first tray case or is separately formed.
12 . The ice maker of claim 7 , further comprising a second tray case coupled to the second portion of the tray.
13 . A refrigerator comprising:
a cabinet including a storage chamber and a door that opens and closes the storage chamber; and
an ice maker of claim 1 .
14 . An ice maker comprising:
a tray including a first portion and a second portion, the first portion and the second portion being configured to define a cell that is a space formed to receive a liquid; and
a transparent ice heater configured to supply heat to the cell,
wherein the second portion moves relative to the first portion between:
a first position where the first portion contacts the second portion to form the space and the liquid in the space is phase-changed into ice, and
a second position where the first portion and the second portion are spaced apart from each other; and
wherein, when a start command of a test mode is input during an operation of the transparent ice heater, the transparent ice heater is configured to be turned off.
15 . The ice maker of claim 14 , wherein, when the start command of the test mode is input, the second portion moves in a first direction.
16 . The ice maker of claim 14 , wherein, after the transparent ice heater is turned off, the second portion moves in a first direction.
17 . The ice maker of claim 15 , wherein the second portion moves toward the second position.
18 . The ice maker of claim 17 , wherein, the second position is an ice separation position, the ice is separated from the tray while the second portion moves toward the second position.
19 . The ice maker of claim 17 , wherein the second position is a liquid supply position, the liquid being supplied to the space when the second portion is in the liquid supply position.
