In addition, those skilled in the art can combine the different embodiments or examples and the features of the different embodiments or examples described in this specification without mutual contradiction. 
     In a first aspect,  FIG.  1    is a schematic diagram showing the overall structure of an ice making system according to an embodiment of the present application. As shown in  FIG.  1   , the ice making system provided by the embodiment of the present application includes an ice making assembly and a water collecting tank  6  located below the ice making assembly. The ice making assembly is configured to make ice, and the water collecting tank  6  is configured to collect ice making water in the ice making process. Here, “the water collecting tank  6  located below the ice making assembly” means that the water collecting tank  6  is located below the ice making assembly in the direction of water flow. It is not required that the water collecting tank  6  is located directly below the ice making assembly, but the water collecting tank  6  may also be located diagonally below the ice making assembly, which is also within the protection scope of the present application. 
     In the ice making process, the ice making water will splash outside under the action of impact force and drip onto other parts. In addition, the temperature in the ice making system is lower than 0° C., therefore, in this process, it is easy to produce condensed water on the internal components of the ice making system, such as the side walls and bottom of the water distributor, which drips into the ice storage box. 
     Accordingly, in some embodiments, a water diversion ice rake structure  5  is further included in this embodiment.  FIGS.  2  to  5    are schematic structural diagrams of the water diversion ice rake structure according to an embodiment of the present application. As shown in  FIGS.  2  to  5   , the water diversion ice rake structure  5  includes: 
     a pair of water receiving lateral wings  51 , each of which is constructed with a rotary end and a free end. As shown in  FIG.  1   , an upper end of the water receiving lateral wing  51  is the rotary end, a lower end of the water receiving lateral wing  51  is the free end, and the pair of water receiving lateral wings  51  are rotatably disposed on opposite sides of the ice making assembly through the respective rotary ends to rotate between an ice making position and an ice falling position. 
     Here, it should be noted that the “ice making position” refers to a position where the pair of water receiving lateral wings  51  are located during the ice making process of the ice making assembly, and the “ice falling position” refers to a position where the pair of water receiving lateral wings  51  are located when ice cubes fall during the deicing process of the ice making assembly. For a pair of water receiving lateral wings  51 , when they are in the above-mentioned different positions, they will be configured into different configurations and states, and these configurations and states will be described in more detail below in conjunction with the accompanying drawings. 
     Here, it should also be noted that the “opposite sides of the ice making assembly” may specifically means that a pair of water receiving lateral wings  51  are arranged on opposite sides along the length direction of the ice making assembly, or a pair of water receiving lateral wings  51  are arranged on the opposite sides along the width direction of the ice making assembly. Of course, a pair of water receiving lateral wings  51  may also be arranged in other suitable positions. In the present embodiment, a case where the pair of water receiving lateral wings  51  are arranged on opposite sides of the ice making assembly along the length direction is taken as an example for description. 
       FIG.  9    is a longitudinal cross-sectional view of a water diversion ice rake structure at an ice making position according to the present embodiment. As shown in  FIG.  9   , at the ice making position, the free ends of the pair of water receiving lateral wings  51  are butted in the space between the ice making assembly and the water collecting tank  6  to form a closure space, and the opening of the closure space faces the ice making assembly. One side of the closure space is constructed as a water outlet  53  which communicates with the water collecting tank  6 . As a result, the water collected in the closure space will be discharged into the water collecting tank  6  through the water outlet  53  for collection, which facilitates the reuse. 
     In the ice making system of the embodiment of the present application, a water diversion ice rake structure  5  is provided on the basis of the traditional ice making system, and a pair of water receiving lateral wings  51  are butted between the ice making assembly and the water collecting tank  6  to form a closure space during ice making, so as to intercept the condensed water formed from the sides and bottom of the ice making assembly and the water splashing out of the ice making assembly during ice making, the intercepted water may fall into the closure space, thereby effectively solving the problems of condensed water dripping out and water splashing during ice making. 
     Wherein the “water splashing out” includes the water splashed out when the water flow in the ice making assembly scour the ice tray  2  and the water splashed out of the water collecting tank  6  when the water flow enters the water collecting tank  6  during ice making. 
     The condensed water may be produced on the surfaces of the ice tray  2  and the water outflow mechanism in the ice making assembly. Of course, other components inside the ice making system will also have condensed water. 
     Wherein, at the ice falling position, the free ends of the pair of water receiving lateral wings  51  are separated from each other to form an ice falling port. After ice making is completed, the ice cubes are dropped from the ice falling port and stored. 
     In this embodiment, the closure space is provided between the ice making assembly and the water collecting tank  6 , and covers at least the two sides and bottom of the ice making assembly, so as to ensure that both the water splashed out due to the water flow scouring the ice tray  2  and the condensed water generated on the two sides and bottom of the ice making assembly fall into the closure space. In addition, since the water flow does not directly flow into the water collecting tank  6 , water may be prevented from splashing outward from the water collecting tank  6 . 
     In order to ensure the water receiving effect of the water receiving lateral wings  51 , the orthographic projection area of the closure space is larger than the orthographic projection area of the ice making assembly. 
     In order to facilitate the storage of ice cubes, according to an embodiment of the present application, the ice making system further includes an ice storage box  7  located below the ice making assembly. The ice storage box  7  is provided with an ice inlet at an upper end, and the ice cubes having been deiced by the ice making assembly fall into the ice storage box  7  from the ice inlet and are stored in the ice storage box  7 . 
     In the prior art, when ice cubes fall into the ice falling passage, the ice cubes will fall randomly, and even pop out of the ice storage box  7  because of no restriction. 
       FIG.  10    is a longitudinal cross-sectional view of a water diversion ice rake structure at an ice falling position according to the present embodiment. As shown in  FIG.  10   , at the ice falling position described in this embodiment, the free ends of the pair of water receiving lateral wings  51  are separated from each other to form an ice falling passage from the ice falling port toward the ice inlet of the ice storage box  7 , and the ice cubes fall into the ice storage box  7  via the ice falling passage for storage. 
     Lateral Wing 
     In this embodiment, condensed water and splashed water are intercepted by the closure space formed by the pair of water receiving lateral wings  51 , and the condensed water and the splashed water are avoided from dripping into the ice storage box  7  which affects the quality and accuracy of the ice cubes. 
     It should be noted here that during deicing, the deiced ice cubes are firstly collected in the closure space. After the deicing is completed, the pair of water receiving lateral wings  51  are rotated in opposite directions to open the ice falling passage, and all ice cubes fall into the ice storage box  7  along the ice falling passage. Specifically, when the ice cubes fall, the water receiving lateral wings  51  form a shield that prevents ice cubes from falling outside the ice falling passage, which may guide the ice cubes to fall into the ice storage box  7  totally and accurately. Here, “rotating in opposite directions” means directions opposite to the directions in which the pair of water receiving lateral wings  51  are rotated toward the ice making position. 
     According to an embodiment of the present application, as shown in  FIG.  9   , the ice making assembly includes at least one ice tray  2 . The ice tray  2  includes a plurality of ice tray units arranged side by side, and an evaporator or other cooling unit is disposed on the backside of the ice tray  2  for cooling the ice tray  2 . When ice is made normally in the ice tray  2 , water flows over the water flowing surface of each ice tray unit of the ice tray  2 , and the water is gradually condensed into ice when it is cooled. As shown in  FIG.  1   , a heating wire  4  on the backside of the ice tray  2  is configured to heat the ice tray  2  for deicing when needed. 
     According to an embodiment of the present application, in order to speed up deicing, as shown in  FIGS.  2  to  5   , the water diversion ice rake structure  5  further includes ice rake teeth  52 , which are disposed at the rotary end of at least one water receiving lateral wing  51  and face the ice outlet side of the ice making assembly. Namely, from which side of the ice making assembly ice is out, the corresponding side is provided with the ice rake teeth  52 . During deicing, the rotary end of the water receiving lateral wing  51  rotates, while the water receiving lateral wing  51  is driven to rotate, the ice rake teeth  52  are driven to rotate to push the ice cubes to fall into the ice storage box  7  along the ice falling passage. Applying thrust to the ice cubes through the ice rake teeth  52 , on the one hand, may help the ice cubes to quickly leave the ice tray  2  and save deicing time, and on the other hand, may give the ice cubes a thrust in a specified direction to increase the orderliness of falling of ice cubes. 
     When ice is made normally in the ice tray  2 , the ice rake teeth  52  do not affect the normal ice making. Specifically, the ice rake teeth  52  are inclined toward the water flowing surface of the ice tray  2 , and the top ends of the ice rake teeth  52  are close to the water inlet of the ice tray  2 . 
     When the adhesive force between the ice cube and the ice tray  2  is small, as shown in  FIG.  10   , the ice rake teeth  52  are driven to rotate under the rotation of the rotary end of the water receiving lateral wing  51 , and a thrust is applied to the water outlet  53  of the ice tray  2  from the water inlet of the ice tray  2 , that is, from the upper end of the ice cubes, thereby saving the energy used for heating, ensuring ice cubes having small melting surfaces and good quality, as well as enabling the ice cubes to fall smoothly into the ice storage box  7  along the water outlet  53  of the ice tray  2 . 
     In an embodiment, in order to improve the ice making efficiency, the ice making assembly includes a pair of ice trays  2 , and backsides of the pair of ice trays  2  are disposed opposite to each other, as shown in  FIGS.  9  and  10   . Combined as shown in  FIG.  1   , an evaporator  3  and a heating wire  4  are arranged between the pair of ice trays  2 , and the evaporator  3  and/or air cooling are used to provide cold capacity to the ice tray  2  to make ice. After the ice making is completed, the ice tray  2  is heated by the heating wire  4  or a heating tube so that the ice cubes are separated from the ice tray  2  to ensure smooth ice falling. 
     According to an embodiment of the present application, when a pair of ice trays  2  is provided, the rotary ends of the pair of water receiving lateral wings  51  may be provided with ice rake teeth  52 , that is, the ice rake teeth  52  are provided on one side of each ice tray  2  to assist in the deicing of each ice tray  2  respectively, so as to maintain the consistency of the ice falling from the ice trays  2  on both sides. 
     According to an embodiment of the present application, in a case that a pair of ice trays  2  are provided, a pair of ice inlets are provided at intervals at the upper end of the ice storage box  7 , the water collecting tank  6  is disposed above the pair of ice inlets, and the length direction of the water collecting tank  6  is along the length direction of the ice storage box  7 . In addition, in order to ensure that ice cubes may smoothly fall into the ice storage box  7  without falling into the water collecting tank  6 , the width of the water collecting tank  6  should not be too large. Further, the side wall of the water collecting tank  6  may also be used as a shield when the ice cubes fall, and the ice falling passage is divided into two ice falling areas to facilitate the ice cubes falling from the ice trays  2  on both sides respectively. 
     Ice doors  71  are hinged outside the pair of ice inlets on the ice storage box  7 . “Outside” here refers to the side of the ice inlet away from the water collecting tank  6 . The ice door  71  is driven to rotate by a hinged shaft, and opens and closes in horizontal and vertical states. Specifically, when the ice door  71  is in the closed state, it is horizontally arranged at the ice inlet, and the ice door  71  is vertically arranged in the open state. The free end of the water receiving lateral wing  51  on the corresponding side abuts against the upper end of the ice door  71 , so that a continuous shielding side wall is formed from the water receiving lateral wing  51  to the ice door  71 , which may reliably guide and shield the ice cubes, and ensure that the ice cubes will not be ejected out from the ice storage box  7 . 
     Of course, it is also possible to arrange only one ice door  71  as needed. 
     According to an embodiment of the present application, the ice rake tooth  52  tapers from its root outward along a length direction to form a tip, so as to facilitate the application of thrust to the ice cubes, and to avoid interference with the ice tray  2  during the rotation process. 
     According to an embodiment of the present application, the ice tray  2  includes a plurality of ice tray units disposed side by side, allowing multiple ice cubes to be made at the same time so as to improve ice making efficiency. A plurality of ice rake teeth  52  are disposed at intervals along a length direction of the rotary end of the water receiving lateral wing  51 , and the plurality of ice rake teeth  52  are in one-to-one correspondence with the plurality of ice tray units.

       FIGS.  6  to  8    are schematic diagrams showing the structure of the water receiving lateral wings of this embodiment. As shown in  FIGS.  6  to  8   , according to an embodiment of the present application, each of the pair of water receiving lateral wings  51  includes a water stopping side wall  51 - 1  extending downward along the respective rotary end and a water receiving side wall  51 - 2  extending to the opposite from the water stopping side wall  51 - 1  and inclined downward, forming a rough L-shaped structure. In order to optimize the structure, the junction of the water stopping side wall  51 - 1  and the water receiving side wall  51 - 2  is in a circular arc transition connection. 
     In order to have a larger contact area after the pair of water receiving lateral wings  51  are butted, and to ensure the reliability of the connection and prevent water leakage, in this embodiment, a downwardly extending flanging  51 - 3  is provided at a bottom end of the water receiving side wall  51 - 2 . 
     In order to ensure the hermeticity of the pair of water receiving lateral wings  51  after being butted, in an embodiment, the bottom end of at least one water receiving side wall  51 - 2  is provided with a sealing structure  55  extending to the flanging  51 - 3 , and the sealing structure  55  may be a silicone pad, food grade rubber pad, etc. In order to ensure the hermetic effect, for example, a silicone pad may be provided at the bottom end of one water receiving side wall  51 - 2 , and the silicone pad has an extension end extending outward. The bottom end of the other water receiving side wall  51 - 2  is provided with a groove. After the pair of water receiving lateral wings  51  are butted, the extension end of the silicone pad extends into the groove. In addition, the silicone pad extending to the flanging  51 - 3  is clamped between a pair of water receiving side walls  51 - 2 , and thus good hermeticity effect is provided. Moreover, the outer surface of the silicone pad may also be provided with a sawtooth structure, and a matching sawtooth structure is provided on the opposite flanging, so as to further ensure sufficient hermeticity. 
     According to an embodiment of the present application, as shown in  FIG.  6   , in order to ensure that the water collected in the closure space may flow smoothly to the water outlet  53 , the water receiving side wall  51 - 2  is configured to be inclined toward the water outlet  53 , and is open on a side provided with the water outlet  53  to facilitate the flow of water, and is provided with a shielding wall  51 - 4  on a side away from the water outlet  53  to prevent water from flowing out of the water collecting tank  6  from the other side of the water receiving side wall  51 - 2 . 
     According to an embodiment of the present application, in order to facilitate the rotational connection of the pair of water receiving lateral wings  51  and the ice making assembly, each of the rotary ends of the pair of water receiving lateral wings  51  is provided with a rotary shaft  54  whose axial direction extends along a length direction of the ice making assembly, to drive the water receiving lateral wings  51  to open and close along the length direction of the ice making assembly. 
     In order to fix the position of the water receiving lateral wing  51 , the rotary shaft  54  of the water receiving lateral wing  51  may be fixed to the side wall of the ice making assembly through a bearing seat. 
     According to an embodiment of the present application, as shown in  FIG.  1   , in order to automatically drive the water receiving lateral wing  51  to rotate, a driving mechanism is further included. The driving mechanism is connected to the rotary shaft  54  of one of the water receiving lateral wings  51 . The driving mechanism may be a driving motor  9  whose output shaft is connected with a driving interface of the rotary shaft  54 , and the rotary shaft  54  is driven to rotate synchronously through the rotation of the driving motor  9 . 
     In order to reduce the number of driving motors  9  and save costs, the rotary shafts  54  of the pair of water receiving lateral wings  51  are connected to each other through a linkage  56 . That is, the driving motor  9  drives one water receiving lateral wing  51  to rotate, and the other water receiving lateral wing  51  is driven to rotate synchronously through the linkage  56 . In this embodiment, the linkage  56  may be a pair of gears that mesh with each other, or may be a partial gear structure provided with meshing teeth, such as a sector-toothed sector structure, or, may also be other structures such as a connecting rod, as long as it can ensure the opening or closing of the pair of water receiving lateral wings  51 . It should be understood, of course, that in an alternative embodiment, it is also feasible to equip a driving mechanism for each of the pair of water receiving lateral wings  51 , depending on the specific usage conditions, which is not defined in the present application. 
     According to an embodiment of the present application, the ice making assembly further includes a water outflow mechanism. As shown in  FIG.  1   , the water outflow mechanism includes a water distributor  1  which supplies water evenly to each ice tray unit through water distribution branch hoses in one-to-one correspondence with the ice tray units, so as to achieve the consistency of ice cube forming in each ice tray unit. 
     In addition, the water collecting tank  6  is connected to a water tank  11  through a drain hose, a water pump  12  is provided on the drain hose, and the water distributor  1  is connected to the water tank  11 . Through the work of the water pump  12 , the water in the water collecting tank  6  is discharged into the water tank  11  through the drain hose, and thus the ice making water is recycled. 
     In this embodiment, a water stopper, such as a water retaining cover, is provided on an outer side of a connection between the water outlet  53  and the water collecting tank  6 , to prevent the water flowing out of the water outlet  53  from splashing out of the water collecting tank  6 . 
     In an embodiment of the present application, as shown in  FIG.  1   , the ice storage box  7  is provided with an ice discharging mechanism  8  which is connected to an ice discharging motor, and the ice discharging mechanism  8  is driven to rotate by the ice discharging motor to achieve automatic ice discharging. 
     Specifically, the ice discharging mechanism  8  may be a spiral shaft. When the spiral shaft rotates, the ice cubes move along a spiral groove of the spiral shaft to facilitate ice discharging. 
     Specifically, the water outflow mechanism is connected to the water tank  11 , and the water in the water tank  11  and the collected water in the water collecting tank  6  are supplied to the ice tray  2  through the water outflow mechanism to make ice. A water valve  10  is arranged on a connecting pipeline between the water distributor  1  and the water tank  11  and may be switched on and off according to the demand of ice making. A water level detector is mounted in the water tank  11  and configured to detect the height of the water level, and when the water level drops to a preset value, the outside will be notified to supply water to the water tank  11 . The ice making system is disposed in a housing on which an observation door  13  is provided, and the internal operation of the ice making system may be observed through the observation door  13 . 
     In a second aspect, an embodiment of the present application further provides a refrigeration apparatus, including but not limited to a refrigerator, which includes the ice making system in the above-mentioned technical solutions. 
     Since the refrigeration apparatus of the embodiment of the present application includes the ice making system described above, it may not only solve the problems of condensed water dripping out and water splashing outward during ice making caused by internal components of the ice making system, but also ensure that the ice cubes fall accurately into the ice storage box. The refrigeration apparatus is convenient to use, and the ice cubes made are of good quality and high precision.
