Referring to fig. 1 to 7, a preferred embodiment of the present utility model provides an icemaker, which is preferably used to make transparent bullet ice.

Specifically, referring to fig. 1 and 2 in combination, an ice maker includes a water storage box 10, an ice making box 20, a refrigerating device 30, and an infusion assembly 40. In this embodiment, the water storage box 10 is used for storing water required for ice making, and is provided to the ice making box 20 through the infusion assembly 40, and the refrigerating device 30 is used for providing cold energy required for ice making.

Specifically, as shown with reference to fig. 3 and 4 in cooperation, the ice making housing 20 has an ice making chamber 21 and an ice making port 22 exposing the ice making chamber. In this embodiment, the ice making housing 20 is opened, and the ice making chamber 21 is for containing water for making ice.

Further, the ice making housing 20 can pivot with respect to the water storage housing 10 to switch between an ice making position and a discharging position. In this embodiment, the ice making housing 20 and the water storage housing 10 can be rotated relatively. The ice-making housing 20 in fig. 3 and 4 is in the ice-making position with the ice-making port 22 at the top of the ice-making housing 20.

Specifically, the refrigerating device 30 includes an ice making column 31, and at least part of the ice making column 31 extends from the ice making port 22 into the ice making chamber 21 when in the ice making position. In this embodiment, when the ice making housing 20 is at the ice making position, the ice making pillars 31 extend into the ice making chamber 21 and contact water in the ice making chamber 21. At this time, after the cold generated by the refrigerating device 30 is transferred to the ice making column 31, the cold is continuously transferred to the water in the ice making chamber 21 through the ice making column 31, so that the water in the ice making case 20 is frozen into ice and finally is frozen on the ice making column 31. Since the ice making pillars 31 have a columnar structure, the ice cubes formed in the ice making pillars 31 have a bullet shape.

Specifically, the infusion set 40 includes an infusion tube 41 that communicates the water storage box 10 with the ice making box 20. In the present embodiment, the infusion set 40 is configured to conduct the water storage tank 10 and the ice making housing 20 by the infusion tube 41, so that the water in the water storage tank 10 is delivered to the ice making housing 20, and the water injected into the ice making housing 20 can be precooled with respect to the water supply from the external water source.

Further, the liquid feeding tube 41 has a surge portion 41a fixed in the ice making chamber 21. In this embodiment, the water-flushing portion 41a is located in the ice making chamber 21, the water-flushing portion 41a is kept relatively stationary with the ice making housing 20, and the water-flushing portion 41a can rotate relatively with the water storage housing 10.

Specifically, the inrush portion 41a has an inrush port 41b that communicates with the inside of the ice making cavity 21. In this embodiment, the water in the water-flushing portion 41a continuously flows into the ice-making cavity 21 through the water-flushing port 41b, and the water in the ice-making cavity 21 is disturbed during the continuous water-flushing of the water-flushing port 41b, so that the water-flushing operation can be formed in the ice-making cavity 21, and the overflow of air bubbles in the water is accelerated, so that the ice cubes formed on the ice-making column 31 are bubble-free and transparent.

Further, the inrush current portion 41a is disposed opposite to the ice making port 22. In the present embodiment, the water flow of the water gushing port 41b is formed around the water gushing portion 41a, thereby disturbing the water around the water gushing portion 41a and accelerating the overflow of the air bubbles in the water around the water gushing portion 41a. Since the water-flowing portion 41a is opposite to the ice-making opening 22, the air bubbles overflowing from the water around the water-flowing portion 41a are directly discharged from the ice-making opening 22, so that the discharge of the air bubbles in the ice-making cavity 21 is accelerated, the air bubbles in the formed ice cubes are reduced, and the ice cubes are more transparent.

After the water in the water storage box 10 is led into the water flushing part 41a, the water flushing part 41b on the water flushing part 41a is utilized to form water flushing in the ice making box 20, so that the water in the ice making box 20 continuously sprays towards the ice making opening 22, bubbles in the water flushing are accelerated to overflow through the ice making opening 22, and the ice making effect is improved.

Specifically, the ice-making housing 20 has a bottom wall 23 and a side wall 24 connected to the periphery of the bottom wall 23 and surrounding the bottom wall 23 to form the ice-making opening 22, and the inrush portion 41a is fixedly connected to the bottom wall 23. In this embodiment, as shown in fig. 3, when the ice making housing 20 is at the ice making position, the bottom wall 23 is located at the bottom of the ice making housing 20, and the ice making port 22 is located at the top of the ice making housing 20, and the ice making port 22 is vertically opposite to the water flowing portion 41a because the water flowing portion 41a is fixed to the bottom wall 23. Therefore, when the ice making housing 20 is at the ice making position, in the process of injecting water into the ice making housing 20 through the water flow part 41a, water flow is injected from the bottom of the ice making housing 20, and after gradually filling the whole ice making cavity 21, water flow overflows from the ice making opening 22 at the top of the ice making housing 20, so that flowing water is formed in the ice making housing 20, and the made ice cubes are transparent and bubble-free.

Moreover, when the ice making housing 20 is at the ice making position, since the water-flushing portion 41a is opposite to the ice making opening 22 along the vertical direction, the water filling opening of the ice making housing 20 is opposite to the water overflow opening along the vertical direction, so that the flowing water flow in the ice making housing 20 penetrates through the whole ice making cavity 21 along the vertical direction, the flowing water range covers the whole ice making cavity 21, the overflow of air bubbles in the ice making housing 20 is accelerated, and the made ice cubes are bubble-free and transparent.

In addition, the inrush current portion 41a is fixed to the bottom wall 23, and interference between the inrush current portion 41a and the ice cubes on the ice making column 31 and the ice making column 31 during rotation of the ice making housing 20 can be avoided.

Further, the surge portion 41a has a plurality of surge ports 41b. In the present embodiment, the water flow in the water-pouring portion 41a flows into the ice making chamber 21 through the plurality of water-pouring portions 41b, and the water injection speed in the ice making chamber 21 is accelerated, thereby accelerating the water flow speed in the ice making chamber 21.

Also, the plurality of the inflow openings 41b are uniformly distributed throughout the ice making chamber 21 such that water flow disturbance exists throughout the ice making chamber 21, and water throughout the ice making housing 20 is discharged with bubbles. In addition, the plurality of the water gushing openings 41b are uniformly arranged on the water gushing portion 41a, so that the water outlet speeds of the water gushing openings 41b are the same, water flow gushing in the ice cavity is the same, and interaction among the water gushing flows in the ice making cavity 21 is reduced.

Further, each of the inflow ports 41b is opened toward the ice making port 22. In this embodiment, all the spouting ports 41b are directly spouted toward the direction of the ice making port 22, so that the overflow of bubbles in the spouting water from the ice making port 22 is accelerated, and the energy loss of the spouting water is reduced.

Further, the refrigerating device 30 includes the ice making pillars 31 corresponding to the number of the inrush current ports 41b. In the present embodiment, the number of the inrush current ports 41b is equal to the number of the ice making columns 31, so that it is ensured that all bubbles in the water in the ice making housing 20 overflow when a plurality of ice making columns 31 make ice at the same time. The axes of each ice making column 31 are parallel to each other.

Further, in the ice making position, each ice making column 31 is disposed opposite to each of the water spouts 41b. In this embodiment, as shown in fig. 3 and 4, each of the inrush current ports 41b is disposed opposite to each of the ice making columns 31, i.e., the inrush current ports 41b are in one-to-one correspondence with the ice making columns 31, and each of the inrush current ports 41b is opposite to each of the ice making columns 31. Therefore, the water flow discharged from each of the water-flow ports 41b is gushed toward each of the ice-making columns 31, and the water around each of the ice-making columns 31 is disturbed, so that the overflow of air bubbles in the water around the ice-making columns 31 is accelerated, and the ice cubes formed on the ice-making columns 31 are bubble-free and transparent.

Specifically, as shown in fig. 4, the ice-making housing 20 further includes a positioning groove 25 provided on the bottom wall 23 and matched with the surge portion 41a. In this embodiment, as shown in fig. 2, the refrigerating device 30 further includes a refrigerant pipe 32 connected to the ice making column 31, and the refrigerant pipe 32 is connected to the evaporator, the condenser and the compressor to form a refrigerating circuit. The refrigerant pipe 32 is connected to the ice making column 31, so that the refrigerant in the refrigeration circuit flows into the ice making column 31 to cool the ice making column 31. Since the ice making columns 31 are uniformly distributed in an array, the refrigerant tube 32 is preferably provided in a "U" shape. And since the inrush current 41b is opposite to the ice making column 31, it is preferable to provide the inrush current portion 41a in a "U" shape matched with the refrigerant pipe 32 and to provide the positioning groove 25 in a "U" shape matched with the inrush current portion 41a.

The current-flowing portion 41a adopts a "U" type structure, so that the current-flowing portion 41a is fully distributed at the bottom of the whole ice-making cavity 21, and a plurality of current-flowing openings 41b are uniformly arranged on the current-flowing portion 41a at intervals along the water flow path in the current-flowing portion 41a, so that the current-flowing generated by the current-flowing openings 41b is uniformly distributed at all positions in the ice-making cavity 21.

Further, the ice maker further includes a fixing member 50 coupled to the ice making housing 20. In this embodiment, the fixing member 50 is fixed to the ice making housing 20 and is positioned on the edge of the positioning groove 25.

Specifically, the surge portion 41a is disposed in the positioning groove 25 and abuts against the fixing member 50. In this embodiment, as shown in fig. 4, taking an example when the ice making housing 20 is at the ice making position, after at least part of the current flowing portion 41a extends into the positioning groove 25, the current flowing portion 41a is limited from being offset in the horizontal direction; the fixing member 50 is abutted against the top of the current flowing portion 41a, so that the current flowing portion 41a is restrained from being offset in the vertical direction, and therefore, the installation and the disassembly are facilitated.

Specifically, the water storage box 10 has a mounting chamber 11 and a water storage chamber 12 communicating with the mounting chamber 11. In the present embodiment, the installation chamber 11 and the water storage chamber 12 are arranged in the vertical direction and penetrate each other.

Further, the infusion set 40 further includes an infusion pump 42 disposed on the infusion tube 41. In this embodiment, as shown in fig. 3, the infusion pump 42 pumps water in the water storage chamber 12 into the ice making chamber 21 to meet the water requirement for making ice.

In some embodiments, the infusion pump 42 may also draw water from the ice making cavity 21 into the water storage cavity 12, facilitating drainage of the ice making cavity 21. Or the infusion pump 42 can pump water in the water storage cavity 12 into the ice making cavity 21 and pump water in the ice making cavity 21 into the water storage cavity 12, so that bidirectional conduction is realized.

Specifically, the ice-making housing 20 is pivotally connected to the water storage housing 10. In this embodiment, the ice making housing 20 is pivoted to the water storage housing 10 using shaft-shaped protrusions at both ends so that the housing portion of the ice making housing 20 can be rotated in the installation cavity 11. The infusion tube 41 further includes a connection portion, preferably a hose, connecting the infusion pump 42 to the in-rush portion 41a to facilitate co-rotation of the in-rush portion 41a with the ice making housing 20.

Specifically, the ice making housing 20 is located above the water storage chamber 12, and the ice making port 22 is exposed to the inside of the installation chamber 11. In this embodiment, when the ice making housing 20 is at the ice making position, the infusion pump 42 continuously pumps water in the water storage cavity 12 and fills the ice making cavity 21, and the liquid in the ice making housing 20 overflows through the ice making port 22, and as the ice making port 22 is exposed in the mounting cavity 11, the liquid overflowed by the ice making housing 20 flows to the mounting cavity 11 and finally falls into the water storage cavity 12 below the ice making housing 20, so that the infusion pump 42 continuously pumps water, thereby realizing water circulation between the ice making cavity 21 and the water storage cavity 12.

Further, the ice maker further includes an ice bank 60 connected to the water storage bin 10, the ice bank 60 having an ice storage port 61 exposed in the installation cavity 11. In this embodiment, referring to fig. 1 and 4, the ice storage box 60 is in an open shape with an open top, the ice storage box 60 is slidably connected to the water storage box 10, and is movably disposed on the water storage box 10 in a push-pull manner, so as to facilitate the use of ice cubes by a user.

Specifically, as shown with reference to fig. 5 and 6, the discharge position has a water discharge state and an ice removal state depending on the orientation of the ice making port 22. In this embodiment, the ice making housing 20 is at different positions during the rotation of the ice making housing 20 with respect to the water storage housing 10. Wherein the ice making housing 20 in fig. 5a and 6a is in the ice making position, and the ice making housing 20 in fig. 5b and 5c and fig. 6b and 6c is in the discharge position. When the ice making housing 20 is at the discharge position, the ice making housing 20 is in a different state according to the orientation of the ice making port 22. Wherein the ice making housing 20 in fig. 5b and fig. 6b is in a water discharge state, and the ice making housing 20 in fig. 5c and fig. 6c is in an ice removal state.

Specifically, with continued reference to fig. 5, in the ice-removing state, the ice-making pillars 31 are exposed to the inside of the mounting chamber 11 and are located directly above the ice storage opening 61. In the present embodiment, when the ice making housing 20 is in the ice-removing state, the ice cubes formed on the ice making housing 31 are dropped into the ice bank 60 below by heating the ice making housing 31 for the user.

Specifically, the ice maker further includes a first heating member 140 disposed at a side of the refrigerant pipe 32 facing away from the ice making column 31, and a second heating member 150 disposed in the water storage chamber 12 and located below the ice bank 60. The refrigerating device 30 is fixedly connected with the water storage box 10, and the ice making column 31 is positioned in the mounting cavity 11. When the ice making housing 20 is at the ice making position, the ice making columns 31 are exposed to the ice making cavity 21. After the ice making is completed, the ice making housing 20 is rotated to an ice removing state so that the ice making columns 31 are exposed to the inside of the installation cavity 11, and at this time, the ice making columns 31 are heated by the first heating member 140 so that ice cubes on the ice making columns 31 fall off and directly fall into the ice storing housing 60. In the process of making ice by the ice making machine, the second heating element 150 heats the water in the water storage cavity 12, so that the water in the water storage cavity 12 can be prevented from freezing, and normal water pumping and water supply of the infusion pump 42 are ensured.

In some embodiments, semiconductor refrigeration may also be used in place of the refrigerant tube 32 or the entire refrigeration unit 30, thereby eliminating the need for the first heating element 140.

Further, the ice maker further includes a water blocking member 70 which is engaged with the ice making housing 20. In this embodiment, the water blocking member 70 is configured to block the liquid discharged from the ice making port 22 when the ice making housing 20 is in the ice making position or the water draining state, thereby preventing the liquid from flowing into the ice storage housing 60.

Specifically, the water guard 70 has a water guard 71 and connection plates 72 connected to both sides of the water guard 71. In this embodiment, referring to fig. 2 and 3, the water baffle 71 has a flat plate structure, and the water baffle 70 is pivotally connected to shaft-like protrusions at two ends of the ice making housing 20 by using the connection plate 72, so that the relative rotation or co-rotation between the water baffle 70 and the ice making housing 20 is realized.

Specifically, the water blocking member 70 is switched between a water guiding state and a avoiding state based on the rotation of the ice making housing 20. In this embodiment, when the water blocking member 70 is driven to rotate during the rotation of the ice making housing 20, the water blocking member 70 can be in different states. Wherein the water deflector 70 in fig. 5a and 5b and fig. 6a and 6b is in a water guiding state, and the water deflector 70 in fig. 5c and 6c is in a dodged state.

Specifically, in the water guiding state, the water blocking plate 71 is located between the ice making housing 20 and the ice bank 60 and covers at least part of the ice storage opening 61. In this embodiment, as shown in fig. 5a and 5b, when the water blocking member 70 is in the water guiding state, the ice making position or the water draining state is provided at the ice making box 20, and the water in the ice making box 20 flows out through the ice making opening 22 and then falls on the water blocking plate 71, flows through the water blocking plate 71 and falls into the water storage cavity 12, so that the liquid is prevented from directly falling into the ice storage box 60, and the normal storage of ice cubes in the ice storage box 60 is ensured. As shown in fig. 5c, when the water blocking member 70 is in the avoiding rotation state, the ice making housing 20 is in the ice removing state, the ice making column 31 is directly exposed above the ice storing opening 61, and the heated ice cubes are separated from the ice making column 31 and fall into the ice storing housing 60, and the water blocking member 70 does not interfere with the fallen ice cubes in the process.

Further, the ice making case 20 is provided with an overflow nozzle 26, and in the water guiding state, the overflow nozzle 26 is located right above the water baffle 71. In this embodiment, the water overflow nozzle 26 is arranged to enable water in the ice making box 20 to overflow from the water overflow nozzle 26 when the ice making box 20 is at the ice making position, so as to ensure stable and uniform water flow of the ice making box 20 falling to the water baffle 71, reduce the splashing amount on the water baffle 71, and prevent the water overflowed from the ice making box 20 from falling into the ice storage box 60.

The ice making housing 20 is preferably provided with an overflow nozzle 26, and the overflow nozzle 26 is positioned at the middle position of the ice making housing. The water overflow nozzle 26 has a water overflow plate of a flat plate structure, which is recessed at the edge of the ice making port 22. When the ice making housing 20 is at the ice making position, the overflow plate 26 and the water baffle 71 incline towards the same side, so that the overflow of the ice making housing 20 can be smoothly and rapidly introduced into the water storage cavity 12, and the water circulation speed between the ice making cavity 21 and the water storage cavity 12 is increased.

Specifically, with continued reference to fig. 2 and 6, the ice maker further includes a first stopper 80 and a second stopper 90 coupled to the ice making housing 20 and cooperating with the water deflector 70. In this embodiment, the connecting plate 72 is located between the first stop member 80 and the second stop member 90, and the first stop member 80 and the second stop member 90 are driven to rotate during the rotation of the ice making housing 20, and when the first stop member 80 or the second stop member 90 abuts against the connecting plate 72, the water blocking member 70 rotates together with the ice making housing 20. Taking fig. 6 as an example, when the ice making housing 20 rotates in the counterclockwise direction, the first stopper 80 abuts against the connecting plate 72, and then drives the water blocking member 70 to rotate in the same direction as the ice making housing 20, i.e. to rotate in the counterclockwise direction; when the ice making housing 20 rotates in the clockwise direction, the second stopper 90 abuts against the connection plate 72, and then drives the water blocking member 70 to rotate in the same direction as the ice making housing 20, i.e., in the clockwise direction.

Specifically, in the ice making position, the connection plate 72 abuts against the first stopper 80. In the present embodiment, the ice making housing 20 is rotated by the driving motor, so that the ice making housing 20 can be kept stationary by the self-locking function of the driving motor after the ice making housing 20 stops rotating. Therefore, when the ice making case 20 is at the ice making position, the water blocking member 70 is in a water guiding state, the ice making case 20 abuts against the side edge of the connecting plate 72 by the first stop member 80, and the water blocking member 70 is kept still due to the fact that the ice making case 20 is kept still, so that the water blocking member 70 is prevented from being deflected due to the impact of water flow.

Specifically, in the discharge position, the connection plate 72 abuts against the second stopper 90. In this embodiment, when the ice making housing 20 is at the discharging position, the ice making housing 20 abuts against the connecting plate 72 by the second stop member 90 and drives the water blocking member 70 to rotate together, so that the ice making housing 20 is switched from the water draining state to the ice removing state, and the ice making pillars 31 are smoothly removed.

Also, when the ice making housing 20 is in the ice removing state, the water blocking member 70 is in the avoiding state, the ice making housing 20 abuts against the side edge of the connecting plate 72 by the second stop member 90, and the water blocking member 70 is kept still due to the fact that the ice making housing 20 is kept still, so that the interference of the water blocking member 70 on the ice removing of the ice making column 31 is avoided.

Further, referring to fig. 3 and 6, the ice maker further includes a supporting member 100 connected to the water storage box 10 and cooperating with the water blocking member 70, wherein in the water guiding state, the supporting member 100 is in contact with the water blocking member 70, and in the avoiding state, the supporting member 100 is out of contact with the water blocking member 70. In this embodiment, the supporting member 100 is fixed on the water storage box 10, and when the water retaining member 70 is in the water guiding state, the supporting member 100 provides a certain limiting force to the water retaining member 70, so as to avoid deflection caused by water impact. In the process that the water retaining member 70 is switched from the water guide state to the avoiding state, the ice making box 20 can drive the water retaining member 70 to be separated from the abutting connection with the abutting member 100, and the abutting member 100 can not influence the rotation of the water retaining member 70 along with the ice making box 20 in the process.

Specifically, referring to fig. 3 and 7, the abutting member 100 includes an abutting ball 101 and a resilient member 102 abutting against the abutting ball 101, when the water blocking member 70 is in a water guiding state, the resilient member 102 abuts against a side of the abutting ball 101 facing away from the water blocking member 70, so as to provide a certain resilient force to the abutting ball 101, so that the abutting ball 101 elastically abuts against the water blocking member 70, and the rotation of the water blocking member 70 along with the ice making case 20 is not affected while a limiting force is provided to the water blocking member 70.

Specifically, the mounting groove 13 is provided on the water storage box 10 to accommodate the rebound member 102 and at least part of the holding ball 101, and the inner diameter of the open end of the mounting groove 13 is made smaller than the largest outer diameter of the holding ball 101, thereby restricting the holding ball 101 from being separated from the mounting groove 13. The mounting groove 13 may be integrally formed with the water storage cartridge 10, or a separate mounting member 170 may be provided to form the mounting groove 13. When the mounting groove 13 is formed using the separate mounting member 170, it is necessary to fixedly attach the mounting member 170 to the water storage cartridge 10 in such a manner that the mounting and dismounting of the abutment member 100 is facilitated.

Further, as further shown with continued reference to fig. 3 and 6, the ice maker further includes a holding groove 160 provided on the water deflector 70 and matched with the holding ball 101. The supporting groove 160 is used for limiting the moving range of the supporting ball 101, so that the supporting member 100 can provide more stable limiting force for the water deflector 70, and meanwhile, the water deflector 70 and the supporting member 100 can be conveniently rotated to be separated from the supporting connection.

Further, as shown with continued reference to fig. 2 and 6, the ice maker further includes a movable member 110 connected to the ice making housing 20, and first and second limiting members 120 and 130 connected to the water storage housing 10 and engaged with the movable member 110. In this embodiment, by providing the internal spline on the movable member 110 and providing the external spline on the shaft-like protrusion at the end of the ice making case, a transmission connection between the movable member 110 and the ice making case 20 is achieved, i.e., the movable member 110 can rotate together with the ice making case 20.

The first limiting member 120 and the second limiting member 130 are fixedly connected with the water storage box 10, and the movable member 110 is located between the first limiting member 120 and the second limiting member 130. Taking fig. 6 as an example, in the process of rotating the ice making housing 20 in the counterclockwise direction, the movable member 110 rotates along with the ice making housing 20 in the counterclockwise direction, and when the movable member 110 contacts the first limiting member 120, the first limiting member 120 can control the driving motor to stop working, and the ice making housing 20 also stops rotating at this time. Also, in the process of rotating the ice making housing 20 in the clockwise direction, the movable member 110 rotates in the clockwise direction together with the ice making housing 20, and when the movable member 110 contacts the second limiting member 130, the second limiting member 130 can control the driving motor to stop working, and the ice making housing 20 stops rotating at this time.

Therefore, the movable member 110, the first limiting member 120 and the second limiting member 130 can avoid excessive rotation of the ice making box 20 in the process of driving the ice making box 20 by the driving motor, thereby avoiding interference between the ice making box 20 and the refrigerating device 30, and avoiding interference between the water retaining member 70 and the water storage box 10.

Specifically, when in the ice making position, the movable member 110 abuts against the first limiting member 120, and when in the ice removing state, the movable member 110 abuts against the second limiting member 130. In the present embodiment, the arrangement of the first and second stoppers 120 and 130 limits the rotation range of the ice making housing 20, i.e., the ice making housing can only rotate between the ice making position and the ice removing state.

Further, in the ice making position, the start-up time of the refrigerating device 30 is not earlier than the liquid output time of the inrush current port 41b. In this embodiment, the start-up time of the refrigeration device 30 is later than or equal to the liquid output time of the inrush port 41b. The start-up time of the refrigerating apparatus 30 refers to the start-up time of the compressor, and the liquid output time of the inrush current 41b refers to the time for injecting water into the ice making cavity 21 from the inrush current 41b.

In the ice making mode that the starting time of the refrigerating device 30 is equal to the liquid output time of the water flushing port 41b, when the liquid in the liquid conveying pipe 41 enters the ice making cavity 21 through the water flushing port 41b or the water flushing port 41b is sprayed to the ice making column 31, the refrigerating device 30 is synchronously started to refrigerate until the ice making cavity 21 is full of water and overflows outwards, the water flow formed by the water flushing port 41b continuously gushes in the ice making cavity 21, water around the ice making column 31 is disturbed, and the overflow of bubbles in the water is accelerated, so that ice cubes formed on the ice making column 31 are bubble-free and transparent.

In the ice making mode that the starting time of the refrigerating device 30 is later than the liquid output time of the water flushing port 41b, when the liquid in the liquid conveying pipe 41 is used for injecting water into the ice making cavity 21 for a period of time through the water flushing port 41b, the refrigerating device 30 is started again for refrigerating until the ice making cavity 21 is full of water and overflows outwards, water flow formed by the water flushing port 41b still continuously flows into the ice making cavity 21, water around the ice making column 31 is disturbed, and the overflow of bubbles in the water is accelerated, so that ice cubes formed on the ice making column 31 are free of bubbles and transparent, and the ice making mode ensures that the ice cubes formed on the ice making column 31 are smoother and meet requirements, and the forming effect of the ice cubes is guaranteed.

Specifically, in the ice making position, the refrigerating device 30 is activated when the ice making chamber 21 is filled with liquid. In the present embodiment, in the ice making mode in which the start-up time of the refrigerating apparatus 30 is later than the liquid output time of the inrush port 41b, it is preferable that the refrigerating apparatus 30 is started to perform the refrigerating when the ice making chamber 21 is filled with water and the overflow starts to be performed outward. That is, when the liquid in the liquid pipe 41 enters the ice making chamber 21 through the inrush port 41b until the ice making chamber 21 is filled with water and overflows outward, the refrigerating device 30 is immediately started to perform refrigeration.

Taking fig. 5 and 6 as an example, when the ice maker starts to make ice, the pre-driving motor controls the ice making box 20 to be at an ice making position, the infusion pump 42 pumps water in the water storage cavity 12 through the infusion pipe 41 and continuously conveys the water into the ice making cavity 21, the ice making column 31 is positioned in the ice making cavity 21 at the moment, and ice cubes are gradually formed on the ice making column 31 after the ice making column 31 contacts with the water in the ice making cavity 21. When the ice making cavity 21 is filled with water, the infusion pump 42 continuously fills water into the ice making cavity 21, water in the ice making cavity 21 flows to the water baffle 71 below through the overflow mouth 26 on the ice making opening 22, flows into the water storage cavity 12 after being guided by the water baffle 71, and is continuously input into the ice making cavity 21 by the infusion pump 42, so that water circulation is formed between the ice making cavity 21 and the water storage cavity 12.

After the ice making of the ice maker is finished, the liquid conveying pump 42 is closed, and the driving motor is controlled to drive the ice making box 20 to rotate clockwise, so that the ice making box 20 is switched to a drainage state from an ice making position, and water in the ice making cavity 21 continuously flows from the ice making opening 22 or the overflow mouth 26 to the water baffle 71 below in the process, flows through the water baffle 71 and falls into the water storage cavity 12. In this process, since the water deflector 70 abuts against the abutment member 100, the water deflector 70 does not deflect during water guiding.

After the ice making case 20 is drained, the driving motor still drives the ice making case 20 to rotate continuously, and at this time, the second stop member 90 on the ice making case 20 drives the water blocking member 70 to rotate clockwise, and drives the water blocking member 70 to be separated from mutual abutting with the abutting member 100. In this process, the driving motor drives the ice making housing 20 to switch from the drainage state to the ice removing state, and the ice making housing 20 drives the water blocking member 70 to switch from the water guiding state to the avoiding state. When the ice making housing 20 is in the ice removing state, the water blocking member 70 is in the escape state, and at this time, the movable member 110 contacts the second limiting member 130, and the second limiting member 130 controls the driving motor to stop rotating. At this time, the first heating member 140 starts to operate and drops the ice cubes on the ice making column 31 into the ice bank 60.

After the ice making machine is de-iced, the driving motor is controlled to drive the ice making box 20 to rotate anticlockwise, and the ice making box 20 is switched from the de-icing state to the ice making state. In this process, after the first stop member 80 abuts against the water stop member 70, the first stop member 80 drives the water stop member 70 to rotate counterclockwise, and drives the water stop member 70 and the abutment member 100 to abut against each other. In the process that the driving motor drives the ice making box 20 to rotate, until the movable piece 110 contacts the first limiting piece 120, the first limiting piece 120 controls the driving motor to stop rotating, the ice making box 20 at the moment is restored to the ice making position, and the abutting piece 100 is abutted against the water retaining piece 70, so that the next round of ice making is performed, and the process is repeated.
