DETAILED DESCRIPTION

[0019] To enable a person skilled in the art better understand the technical solutions of the present invention, the following clearly and completely describes the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are merely some rather than all of the embodiments of the present invention. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] Referring to FIG. 1, an embodiment of the present invention provides a refrigerator 100, including a cabinet 110 and a door used for opening and closing the cabinet 110. The cabinet 110 may be provided with a refrigerating chamber and a freezing chamber therein. An ice making apparatus is mounted in the freezing chamber. Certainly, the ice making apparatus may be mounted on a freezing chamber door, a refrigerating chamber door, or in the refrigerating chamber.

[0021] Referring to FIG. 1 and FIG. 2, the ice making apparatus includes an ice making assembly 210 and an ice storage box 220 under the ice making assembly 210. The ice making assembly 210 may include an ice making rack 211, an ice making tray 212, and a water supply assembly. The ice making rack 211 is fixedly mounted in the cabinet 110 or the door of the refrigerator 100. The ice making tray 212 is connected to the ice making rack 211. The water supply assembly is used for supplying liquid water to the ice making tray 212. The ice making apparatus may separate ice by twisting or by using an ice ejecting apparatus.

[0022] The ice storage box 220 includes an outer box 221 and an inner box 222 arranged in the outer box 221. The outer box 221 has an ice receiving region 223 under the ice making assembly 210 and an ice storage region 224 adjacent to the ice receiving region 223. The ice making apparatus further includes a driving assembly 230. The driving assembly 230 can drive the inner box 222 to move from the ice receiving region 223 to the ice storage region 224.

[0023] In this embodiment, the bottom area of the outer box 221 is greater than the area of the ice making tray 212. A projection, towards a bottom surface of the outer box body 221, of the ice making tray 212 is completely in the bottom surface of the outer box body 221. The ice receiving region 223 may be disposed under the ice making tray 212. Ice discharged from the ice making tray 212 directly falls into the ice receiving region 223. The ice storage region 224 is adjacent to the ice receiving region 223. When the inner box 222 is disposed in the ice receiving region 223, the projection, towards the bottom surface of the outer box 221, of the ice making tray 212 is completely in a bottom surface of the inner box 222, and the bottom surface of the inner box 222 can completely cover the ice receiving region 223. When ice making is started, the inner box 222 may be disposed in the ice receiving region 223, and ice made by the ice making assembly 210 is directly discharged into the inner box 222. When amount of ice in the inner box 222 reaches an upper storage limit of ice in the inner box body 222, the driving assembly 230 drives the inner box 222 to move to the ice storage region 224. At this time, ice made by the ice making assembly 210 directly falls to the ice receiving region 223 of the outer box 221. Specifically, the area of the ice storage region 224 may be equal to the area of the ice receiving region 223, and the bottom area of the inner box 222 may be the same as the area of the ice receiving region 223.

[0024] An internal bottom surface of the outer box 221 is provided with a guide rail 225 extending from the ice receiving region 223 to the ice storage region 224. Rollers 226 matching the guide rail 225 are mounted at a bottom of the inner box 222. The inner box 222 can move from the ice receiving region 223 to the ice storage region 224 along the guide rail 225.

[0025] In this way, as the inner box 222 capable of moving from the ice receiving region 223 to the ice storage region 224 is disposed in the outer box 221 of the ice storage box 220, an internal volume of the ice storage box 220 can be fully utilized, thereby avoiding waste of the internal volume of the ice storage box 220 because ice is accumulated only in the ice receiving region 223 under the ice making tray 212.

[0026] Further, in an embodiment of the present invention, the refrigerator 100 further includes an ice amount detection module and a control module. The ice amount detection module is used for detecting the amount of ice in the ice storage box 220. When the inner box 222 is in the ice receiving region 223, and the ice amount detection module detects that the amount of ice in the inner box 222 reaches the upper storage limit of the inner box 222, the control module controls the driving assembly 230 to drive the inner box 222 to move from the ice receiving region 223 to the ice storage region 224.

[0027] In this embodiment, the ice amount detection module may be used for detecting an amount of ice in the inner box 222 or the outer box 221, or a total amount of ice in the outer box 221 and the inner box 222; and the ice amount detection module may be an ice probing rod 215 on a side of the ice making tray 212, or may be a weight sensor or another sensor. There may be one ice amount detection module; or there may be a plurality of ice amount detection modules used for detecting amounts of ice in different regions. The plurality of ice amount detection modules may use the same ice amount detection mode or different ice amount detection modes.

[0028] The control module may be a control module in a refrigerator 100 system, or may be an independent module disposed on the ice making apparatus and independent of the refrigerator 100 system. The ice making apparatus may further include a position detection module used for detecting whether the inner box 222 is in the ice receiving region 223. The position detection module may be an ultrasonic sensor, an infrared sensor, or an optical proximity sensor mounted in the ice receiving region 223.

[0029] When the inner box 222 is in the ice receiving region 223, ice discharged by the ice making assembly 210 is directly received by the inner box 222. At this time, if the ice amount detection module detects that the amount of ice in the inner box 222 reaches the upper storage limit of the inner box 222, the control module may control the driving assembly 230 to drive the inner box 222 to move from the ice receiving region 223 to the ice storage region 224. After the inner box 222 moves from the ice receiving region 223 to the ice storage region 224, the ice receiving region 223 is in an ice-free state again, and the ice made by the ice making assembly 210 may continue being discharged to the ice receiving region 223.

[0030] In this way, an ice amount is detected by an ice amount sensor. When the amount of ice in the inner box 222 reaches the upper ice storage limit, the inner box 222 is automatically controlled to move from the ice receiving region 223 to the ice storage region 224. Therefore, internal storage space of the ice storage box 220 is fully utilized, and more ice can be stored in the ice storage box 220.

[0031] Further, in an embodiment of the present invention, the control module is further used for: when the ice amount detection module detects that an amount of ice in the outer box 221 or the ice storage box 220 reaches a preset ice storage amount, controlling the ice making assembly 210 to stop making ice.

[0032] In this embodiment, the preset ice storage amount may be an upper ice storage limit, or another value smaller than the upper ice storage limit. An ice amount input module may be disposed on the refrigerator 100. A user may input, according to the user's demand by using the ice amount input module, the preset ice storage amount by which ice is desired to be stored in the ice storage box 220. The control module controls running of the ice making assembly 210 according to the preset ice storage amount input by the user. If the user has not input the preset ice storage amount, it may be considered by default that the preset ice storage amount is the upper ice storage limit.

[0033] In this way, the start/stop of the ice making assembly 210 is automatically controlled according to an ice amount, which is convenient and fast.

[0034] Further, in an embodiment of the present invention, the ice amount detection module includes a motor assembly 214 and an ice probing rod 215. The motor assembly 214 is fixedly mounted on a side of the ice making tray 212. The ice probing rod 215 is rotatably mounted on a side of the ice making tray 212, may be driven by the motor assembly 214, and is used for probing an amount of ice in the ice receiving region 223.

[0035] In this embodiment, after ice separating of the ice making assembly 210 is completed, the motor assembly 214 may be started to drive the ice probing rod 215 to rotate, thereby detecting the amount of ice in the ice receiving region 223. When the inner box 222 is in the ice receiving region 223, ice discharged by the ice making assembly 210 is directly discharged into the inner box 222. At this time, when the ice probing rod 215 detects that the amount of ice in the ice receiving region 223 reaches the upper storage limit, that is, the amount of ice in the inner box 222 reaches the upper storage limit, the driving assembly 230 is controlled to drive the inner box 222 to move from the ice receiving region 223 to the ice storage region 224. After the inner box 222 moves to the ice storage region 224, the ice making assembly 210 continues to make ice. When the inner box 222 is in the ice storage region 224, if the ice probing rod 215 detects that the amount of ice in the ice receiving region 223 reaches the upper ice storage limit, that is, an amount of ice in the outer box 221 or the ice storage box 220 reaches the upper storage limit, the control module controls the ice making assembly 210 to stop making ice.

[0036] In this way, by detecting the amount of ice in the ice receiving region 223 by the ice probing rod 215, the movement of the inner box body 222 and start/stop of an ice making assembly can be controlled, thereby ensuring that internal space of the ice storage box 220 is fully utilized, and the overall structure is simple and compact.

[0037] In another embodiment of the present invention, the ice amount detection module further includes a weight sensor mounted at a bottom of the outer box 221. The weight sensor can detect an amount of ice stored in the ice storage box 220, namely, a total amount of ice stored in the outer box 221 and the inner box 222. An ice amount input module may be disposed on the refrigerator 100. The user may input, by using the ice amount input module, a preset ice storage weight by which ice is desired to be stored in the ice storage box 220. When the weight sensor detects that the amount of ice stored in the ice storage box 220 reaches the preset ice storage weight or an upper ice storage limit of the ice storage box 220, the control module controls the ice making assembly 210 to stop making ice.

[0038] Specifically, in this embodiment, in addition, the amount of ice in the ice receiving region 223 may be detected by the ice probing rod 215. After ice separating of the ice making assembly 210 is completed, the motor assembly 214 is started to drive the ice probing rod 215 to detect the amount of ice in the ice receiving region 223. When the inner box 222 is in the ice receiving region 223, and the ice probing rod 215 detects that the amount of ice in the ice receiving region 223 reaches the upper storage limit, that is, the amount of ice in the inner box 222 reaches the upper storage limit, the driving assembly 230 may be controlled to drive the inner box 222 to move from the ice receiving region 223 to the ice storage region 224. If the weight sensor detects that the amount of ice in the ice storage box 220 reaches the preset ice storage amount, the ice making assembly 210 may be controlled to stop making ice. When the inner box 222 is in the ice storage region 224, if the ice probing rod 215 detects that the amount of ice in the ice receiving region 223 reaches the upper storage limit, or if the weight sensor detects that an ice amount reaches the preset ice storage amount, the ice making assembly 210 is controlled to stop making ice.

[0039] In this way, an amount of ice stored in the ice storage box 220 can be accurately obtained by providing the weight sensor. The weight sensor may be used in combination with the ice probing rod 215, thereby improving control accuracy and preventing ice from overflowing the ice storage box 220 because the ice amount is too large.

[0040] In still another embodiment of the present invention, the ice amount detection module includes a first weight sensor mounted at a bottom of the inner box 222 and a second weight sensor mounted at a bottom of the outer box 221. The first weight sensor can detect the amount of ice stored in the inner box 222. The second weight sensor can detect the amount of ice stored in the ice storage box 220, that is, the second weight sensor can detect the total amount of ice stored in the inner box 222 and the outer box 221.

[0041] In this embodiment, when the inner box 222 is in the ice receiving region 223, if the first weight sensor detects that the amount of ice in the inner box 222 reaches the upper ice storage limit of the inner box 222, the driving assembly 230 is controlled to drive the inner box 222 to move from the ice receiving region 223 to the ice storage region 224. If the second weight sensor detects that the amount of ice in the ice storage box 220 reaches the preset ice storage amount, the ice making assembly 210 is controlled to stop making ice. The preset ice storage amount may be input by the user using the ice amount input module, or may be the upper ice storage limit of the ice storage box 220 set at the factory.

[0042] In this way, the two weight sensors are provided to respectively detect amounts of ice in the inner box 222 and the ice storage box 220, thereby ensuring accuracy of ice amount detection.

[0043] Further, in an embodiment of the present invention, the driving assembly 230 is an electromagnetic driving assembly 230. The driving assembly 230 includes a coil 231 and a magnet 232. The coil 231 is mounted on a side, close to the ice receiving region 223, at an exterior of the ice storage box 220 and faces the ice storage region 224. The magnet 232 is mounted on the inner box 222. The coil 231 is opposite the magnet 232 when the inner box 222 is in the ice receiving region 223. Specifically, an accommodating space for accommodating the magnet 232 is provided in a back wall, adjacent to the coil 231, of the inner box 222.

[0044] The coil 231 may be mounted independent of the ice storage box 220. The coil 231 may be mounted on the cabinet 110 or the door of the refrigerator 100; or an independent bracket used for mounting of the coil 231 may be disposed on a side of the ice storage box 220. The magnet 232 is fixed on the inner box 222 and can move together with the inner box 222.

[0045] In this embodiment, when the inner box 222 is in the ice receiving region 223, and the ice amount detection module detects that the amount of ice in the inner box 222 reaches the upper storage limit, the control module controls the coil 231 to be energized, thereby driving the magnet 232 to drive the inner box 222 to move towards the ice storage region 224. When the ice amount detection module detects that an amount of ice in the outer box 221 or the ice storage box 220 reaches the upper storage limit, the ice making assembly 210 is controlled to stop making ice.

[0046] In an embodiment of the present invention, the ice making assembly 210 is mounted on a side of a back wall of the freezing chamber. A length direction of the ice making tray 212 may be parallel to a width direction of the back wall of the freezing chamber, that is, the ice making tray 212 is transversally disposed in the freezing chamber, thereby facilitating mounting of the ice making assembly 210. The ice storage box 220 is drawably mounted in the freezing chamber. A back wall of the ice storage box 220 is adjacent to the back wall of the freezing chamber. Specifically, the back wall of the ice storage box 220 is adjacent to an air duct cover plate 113 on the back wall of the freezing chamber. The ice receiving region 223 is formed on a side, close to the back wall of the freezing chamber, of the ice storage box 220; and the ice storage region 224 is formed on a side, away from the back wall of the freezing chamber, of the ice storage box 220. The coil 231 is mounted on the back wall of the freezing chamber. Specifically, the coil 231 is mounted on the air duct cover plate 113 on the back wall of the freezing chamber.

[0047] The driving assembly 230 is an electromagnetic driving assembly 230. The coil 231 and the magnet 232 are separated from each other. The user may directly take out the ice storage box 220 to get ice, or merely take out the inner box 222 in the outer box 221 to get ice. After getting the ice, the user only needs to put the inner box 222 back to the ice receiving region 223, or put the ice storage box 220 back to an original position. Therefore, the operation is convenient.

[0048] In summary, according to the ice making apparatus and the refrigerator 100 provided in the present invention, the ice storage box 220 includes the outer box 221 and the inner box 222 arranged in the outer box 221, and the inner box 222 can move in the outer box 221 from the ice receiving region 223 to the ice storage region 224, thereby avoiding an influence on the utilization of the internal volume of the ice storage box 220 caused by accumulation of ice in the ice receiving region 223.
