As shown in fig. 1, 2 and 3, a refrigerator provided in an embodiment of the present application includes:

a case 100 having one side open;

a door 110 openable and closable to close or open the opening;

a freezing chamber 120 located in a storage space formed by the cabinet and the door;

an icemaker 200 located within the freezing chamber 120;

the ice maker 200 includes:

the ice maker includes:

a first fixing frame 1 provided in the freezing chamber 120;

the motor component 2 is arranged at one end of the first fixing frame 1;

one end of the ice making box 3 is connected with the motor component 2 through a first rotating shaft, and the other end of the ice making box is rotatably connected with the first fixing frame 1;

in the ice making box 3, at least one first ice making cell 31 is disposed at both front and rear ends of the first rotating shaft in the length direction, and the depth of the first ice making cell 31 gradually decreases from the middle of the first ice making cell 31 to both ends in the rotation direction of the ice making box 3.

The refrigerator provided by the embodiment of the application is provided with the ice maker in the freezing chamber, and the ice making chamber is cooled by the refrigerator refrigerating system, so that the refrigerator has an ice making function. The ice maker is connected with a water source through the outside and freezes water into ice blocks or ice particles by virtue of the low-temperature freezing action of a freezing chamber where the ice maker is located, so that a user can use the ice blocks or the ice particles. When the ice turning operation is performed, the ice making box is rotated, and ice blocks are made to fall off through unequal torque. After the ice making box rotates for a certain angle, the middle of the ice making box is stressed too much, ice blocks in the middle of the ice making box are easy to fall off, and on the contrary, the two sides of the ice making box are stressed less, so the deformation is small, the phenomenon that the ice blocks in the front and the rear of the ice making box cannot fall off can occur, the ice is not completely removed, next water is injected for making ice, water is injected according to the same water injection amount, the water injection amount is too much, water overflows from ice making cells, and the ice making effect is influenced. In the refrigerator, first ice cube tray is arranged at the front end and the rear end of the ice maker along the length direction of a first rotating shaft, the depth of the first ice cube tray is gradually reduced from the middle to the two ends along the rotating direction of the ice making box, namely the depth of the middle position of each first ice cube tray is maximum, and the depth of the middle position of each first ice cube tray is gradually reduced towards the two sides of the first ice cube tray. The first ice-making grids can also be used for ice shedding normally under the condition of small deformation, so that ice blocks in the first ice-making grids at the front end and the rear end of the ice-making box along the direction of the first rotating shaft are easy to shed.

As shown in fig. 4, in one embodiment of the present application, the first ice-making housings 31 are arranged side by side in the length direction of the first rotation shaft of the ice-making housing 3, and the first ice-making housings 31 are arranged only in one row in the rotation direction of the ice-making housing 3. The ice making box 3 rotates around the first rotating shaft and then twists to remove ice, and the deformation amount difference of the ice making box 3 in the rotating direction is large, so that the depth of the first ice making grids 31 in the rotating direction of the ice making box is set to be deep in the middle and shallow at two ends, only one row of the first ice making grids 31 is arranged, and the depth difference of the row of the first ice making grids 31 is just matched with the deformation amount difference of the ice making box 3. If a plurality of rows of first ice-making grids are arranged along the rotating direction, the depth difference of the first ice-making grids is not matched with the deformation difference of the ice-making box, and the ice-shedding difficulty cannot be correspondingly improved.

As shown in fig. 5, in one embodiment of the present application, the first ice-making housing 31 has a crescent-shaped cross-section in the rotation direction of the ice-making housing 3. As shown in fig. 6, the section of the first ice-making housing 31 in the rotation direction of the ice-making housing may be further made up of: a first diagonal segment 311, a first arc segment 312, and a second diagonal segment 313. The first slope line segment 311 and the first arc-shaped segment 312 smoothly transition at the junction, and the second slope line segment 313 and the first arc-shaped segment 312 smoothly transition at the junction to facilitate the ice cubes to be separated from the ice cube tray.

As shown in fig. 7, in one embodiment of the present application, the depth of the first ice-making housing 31 gradually decreases from the middle to both ends in the length direction of the first rotation shaft of the ice-making housing 3. The amount of deformation of the ice-making housing 3 along the length direction of the first rotation shaft is also large in the middle and small at both sides by twisting for ice removal, and thus, in order to facilitate ice removal of the first ice-making cells 31 along both ends of the first rotation shaft direction, the depth of the first ice-making cells 31 is gradually reduced from the middle to both ends along the length direction of the first rotation shaft of the ice-making housing 3. As shown in one embodiment of the present application, a cross section of the first ice-making housing in the first rotational axis direction is arc-shaped. The cross section of the first ice-making housing 31 in the first rotation axis direction may also be made of: the third oblique line segment, the second arc-shaped segment and the second oblique line segment. The third oblique line section and the first arc-shaped section are in smooth transition at the joint, and the fourth oblique line section and the second arc-shaped section are in smooth transition at the joint, so that ice blocks can be conveniently separated from the ice making grids.

As shown in fig. 4, 7 and 8, in one embodiment of the present disclosure, at least one row of second ice-making compartments 32 arranged in a length direction of the first rotation shaft of the ice-making housing 3 is further provided between the first ice-making compartments 31. The second ice-making cells are easy to de-ice, and square ice-making cells can be adopted. The first ice cube tray 31 is arranged at two ends of the ice making box along the direction of the first rotating shaft, and the second ice cube tray 32 is arranged in the middle of the first ice cube tray 31, so that the problem that ice cubes of the ice cube tray at the end of the ice making box 3 are difficult to fall off is solved, the shape diversity of the ice cubes is increased, and the use scene of the ice maker is widened.

As shown in fig. 1, 9, in an embodiment of the present application, the refrigerator further includes:

an ice bank 300 positioned below the ice-making bank 3;

and the ice detecting rod 4 is connected with the motor assembly 2 and is driven by the motor assembly 2 to rotate by a preset angle so as to detect the ice blocks in the ice storage box 300 and send out an ice making stopping signal when the ice blocks are touched.

In one embodiment of the present application, the refrigerator further includes: a base and a mounting assembly; the ice storage box can be directly placed on the base and used for receiving and storing ice cubes falling from the ice maker, and the mounting assemblies are arranged on two side faces of the base and used for mounting the base on the side wall of the freezing chamber.

The ice detecting rod 4 is connected to the motor assembly 2 through a second rotating shaft and rotates a predetermined angle under the driving of the motor assembly 2 to detect ice cubes in the ice bank 300. When water enters the ice making cells and condenses into ice after a period of time, the ice detecting rod 4 starts to work under the driving of the motor assembly 2 to detect the ice downwards, and if the ice detecting rod 4 does not touch the ice blocks at the moment, the motor assembly 2 controls the ice box 3 to twist, so that the ice blocks fall into the ice storage box 300 from the ice making box 3. Then the motor component 2 controls the ice box 3 to reset, after the ice box reaches the horizontal position, the water pump starts to work, water is injected into the ice box 3 again, ice is made again, and the process is repeated. If the ice detecting rod 4 touches ice blocks, the ice blocks are fully stored in the ice storage box 300, and the ice making motor and the water pump do not work any more, and the ice detecting rod 4 detects the ice blocks again after a while.

In addition, the ice detecting rod 4 may be configured to rotate around the second rotation axis to a height when the ice storage bin 300 is full of ice, or the ice detecting rod 4 may be configured to rotate around the second rotation axis to a height when the ice storage bin 300 reaches 90% of the full ice height, and once the ice detecting rod 4 senses the height and ice cubes are in the ice storage bin 300, a full ice signal or an ice soon-full signal is sent. The ice-detecting rod 4 can also be arranged to rotate a predetermined angle in a horizontal plane below the ice-making box 3, i.e. the ice-detecting rod 4 rotates a predetermined angle in the horizontal plane around a vertical axis, thereby forming an ice-detecting area in the horizontal plane. When the ice detecting rod senses ice blocks at any position in the area, a signal for stopping ice making can be sent out, so that the situation that the ice blocks accumulated at any position in the area by the ice storage box 300 below the ice making box 3 are too high to cause the ice making box 3 and the motor assembly 2 to be clamped by continuous twisting and ice shedding is avoided. The ice detecting area at least comprises the area with the fastest and highest accumulated ice below the ice making box 3. The specific angle range of the predetermined angle may be set according to the sizes of the ice-making bank 3 and the ice bank 300. In order to make the structure more compact while ensuring a sufficiently large ice-detecting area, for example, the predetermined angle may be set in the range of 40 ° to 60 °.
