         2 . The refrigerator of  claim 1 , wherein
 the first tray includes a first sealing portion formed along an edge of the first ice-making cell,   the second tray includes a second sealing portion formed along an edge of the second ice-making cell,   the second tray is movable horizontally with respect to the first tray to engage with the first tray and couple the first ice-making cell to the second ice-making cell, and   while the second tray is engaged with the first tray,
 the second sealing portion overlaps the first sealing portion to prevent leakage from the first ice-making cell and the second ice-making cell. 
   
     
     
         3 . The refrigerator of  claim 2 , wherein
 the first sealing portion includes:
 a recess recessed inward from an outer circumferential surface of the first tray, and 
   the second sealing portion includes:
 a protrusion extending outward from an inner circumferential surface of the second tray and configured to be mountable on the recess to maintain a seal between the first tray and the second tray. 
   
     
     
         4 . The refrigerator of  claim 3 , further comprising:
 a first case formed on one surface of the cover frame to receive the first tray,   wherein the second case is moved horizontally with respect to the cover frame in conjunction with a movement of the rack gear.   
     
     
         5 . The refrigerator of  claim 4 , further comprising:
 a driver configured to generate power; and   a pinion configured to be rotated according to a drive of the driver;   wherein the pinion and the rack gear are engaged to convert a rotational motion of the driver into a linear motion.   
     
     
         6 . The refrigerator of  claim 4 , wherein
 in response to the rack gear being maximally moved in a direction in which the second case moves toward the first case, the elastic member is tensioned and airtightness between the second case and the first case is maintained by an elastic restoring force.   
     
     
         7 . The refrigerator of  claim 3 , further comprising:
 a first ejector including a pressing portion,   wherein the first case includes a through hole formed to correspond to a position of the ice-making cell, and   the pressing portion is configured to pass through the through hole so as to press the first tray.   
     
     
         8 . The refrigerator of  claim 7 , wherein
 the first ejector includes:
 a body configured to support the pressing portion, and 
 a leg extending from each of opposite ends of the body and inserted into respective side portions of the cover frame, 
   the second case includes:
 a protrusion extending from each of opposite ends of the second case to be respectively received in the legs, and 
   in response to the second case being moved in a direction away from the first case, the protrusions interfere with the legs, and the first ejector is moved in a direction closer to the first case such that the pressing portion presses the first tray.   
     
     
         9 . The refrigerator of  claim 7 , further comprising:
 a second ejector fixed to one side of the cover frame and including a pressing portion extending toward the second case,   wherein in response to the second case being moved in a direction away from the first case, the pressing portion of the second ejector passes through the second case so as to press the second tray.   
     
     
         10 . The refrigerator of  claim 1 , wherein
 the ice-making cells of the first tray and the second tray are each configured in a semi-spherical shape.   
     
     
         11 . The refrigerator of  claim 1 , further comprising:
 a cover frame coupled to an inside of the ice-making housing; and   a water path configured on an upper surface of the cover frame to guide the water supplied from the water supplier to flow into the first tray and the second tray,   wherein a plurality of ice-making cells are formed in the first tray and the second tray.   
     
     
         12 . The refrigerator of  claim 11 , wherein
 the water path includes a plurality of flow paths to equally supply water to each of the plurality of ice-making cells of the first tray and the second tray.   
     
     
         13 . The refrigerator of  claim 12 , wherein
 the refrigerator further comprises a controller configured to control the water supplier to supply the water in stages.   
     
     
         14 . The refrigerator of  claim 11 , wherein
 the water path includes a single flow path to guide the water to only one ice-making cell among the plurality of ice-making cells, and   each of the plurality of ice-making cells is configured to have a height difference so that the water overflows the one ice-making cell among the plurality of ice-making cells to sequentially fill each remaining ice-making cell among the plurality of ice-making cells with the water.   
     
     
         15 . The refrigerator of  claim 11 , wherein
 the water path includes a single flow path to guide the water to only one ice-making cell among the plurality of ice-making cells, and   the first tray and the second tray include a connection flow path provided to allow the water, which is supplied to the one ice-making cell, to flow to an adjacent ice-making cell among the plurality of ice-making cells.
