[0002] Ice maker ball mold is a mold used to make spherical ice cubes. Ice maker ball mold belongs to the main structure of ice maker. Its principle is usually to inject liquid water or other suitable liquid into the mold, and then put it into a freezing environment, so that the liquid solidifies in the mold and becomes spherical ice cubes.

[0003] The lower ice ball mold and the upper ice ball mold of the existing ice maker are usually closed by a motor to continuously apply force to keep the lower ice ball mold and the upper ice ball mold closed. However, the ice making time is long and under the action of the gravity of the ice ball and the expansion of water into ice, the lack of a limiting device will cause the lower ice ball mold and the upper ice ball mold to separate slightly, which will lead to the surface of the formed ice ball being not smooth enough. There will be a circle of ice ring at the joint between the lower ice ball mold and the upper ice ball mold, which makes the ice ball not beautiful enough. Utility Model Content

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] like Figures 1 to 7 As shown, the utility model provides a spherical ice mold with good ice-making effect for an ice maker, including a refrigeration chamber 7 fixedly arranged at the lower end of a water tank 1, and a heat-insulating layer is fixedly arranged on the surface of the water tank 1 and the refrigeration chamber 7 to prevent cold air from entering the water tank 1. At the same time, the water tank 1 and the refrigeration chamber 7 are both prior arts, and their specific composition will not be repeated here. The utility model also includes a pumping mechanism fixed inside the water tank 1, and the pumping mechanism includes a submersible pump and a water pipe. The water pipe is located in the middle of the upper opening of the lower ice ball mold 3, so that water can be pumped out of the lower ice ball mold 3 and inside the lower ice ball mold 3 to realize water circulation.

[0029] A driving mechanism 2 for driving the lower ice ball mold 3 to rotate is arranged inside the inner cavity of the refrigeration chamber 7. The driving mechanism 2 is a prior art, which includes a driving motor and a connecting rod fixedly connected to the lower end of the lower ice ball mold 3.

[0030] The bottom of the water tank 1 is fixedly provided with a lower ice ball mold 3 which is connected to the inside of the water tank 1. The upper end of the lower ice ball mold 3 is provided with an opening for water inlet, and the upper end of the opening is flush with the bottom of the water tank 1. The connection between the lower ice ball mold 3 and the water tank 1 (such as Figure 1 As shown), the lower ice hockey mold 3 and the lower ice hockey mold 3 can be spliced ​​into a sphere for making spherical ice. Both sides of the surface of the lower ice hockey mold 3 are fixed with L-shaped buckle plates 6. The structural shape of the L-shaped buckle plates 6 (as shown) Figure 6 As shown), it should be noted that the length of the L-shaped buckle plate 6 is three quarters of the length of the inner cavity of the U-shaped frame 51, which facilitates the L-shaped buckle plate 6 to enter the inner cavity of the U-shaped frame 51.

[0031] The fixing mechanism 5 includes U-shaped frames 51 fixedly arranged on both sides of the lower ice hockey mold 3. The two U-shaped frames 51 correspond to the two L-shaped buckle plates 6. The U-shaped frame 51 is hinged with a buckle 52 at the opening on the side away from the lower ice hockey mold 3. The outer side of the buckle 52 in a vertical state is flush with the surface of the U-shaped frame 51. At the same time, the hook teeth 521 of the buckle 52 are arranged at the opening adjacent to the lower end of the U-shaped frame 51 (such as Figure 4 shown).

[0032] The buckle 52 and the L-shaped buckle plate 6 are both fixed with hook teeth 521 on the side facing each other. The shapes and meshing states of the two hook teeth 521 are as follows: Figure 7 As shown in the figure, the ends of the two hook teeth 521 are both provided with circular chamfers. At the same time, the two contact inclined surfaces 522 are provided to facilitate the separation of the two hook teeth 521. When the lower ice hockey mold 3 is closed, the hook teeth 521 of the buckle 52 and the hook teeth 521 of the L-shaped buckle plate 6 abut and fix each other. When the driving mechanism 2 is powered off, the buckle 52 limits the lifting of the L-shaped buckle plate 6, so that the lower ice hockey mold 3 and the lower ice hockey mold 3 are firmly closed and will not be affected by gravity and the expansion of the ice ball.

[0033] The fixing mechanism 5 also includes a slope 1 522 arranged on the opposite side of the two hook teeth 521. The inclination angle of the slope 1 522 is 5-10 degrees, which needs to be determined according to the size of the lower ice hockey mold 3 and the lower ice hockey mold 3. A slope 2 523 is arranged on the upper side of the hook tooth 521 of the L-shaped buckle plate 6 at a position relative to the L-shaped top head 59. The slope 2 523 facilitates the separation of the two hook teeth 521. The inclination of the slope 2 523 needs to match the inclination angle of the slope 1 522 to achieve a linkage effect. For example, when the L-shaped top head 59 moves slightly on the slope 2 523, that is, the hook tooth 521 of the buckle 52 rotates a certain angle and is slightly separated from the hook tooth 521 of the L-shaped buckle plate 6. This action linkage can be achieved, which can facilitate the separation of the two hook teeth 521. It should be noted that the length of the hook teeth 521 of the buckle 52 is one quarter of the length of the buckle 52. When the lower ice hockey mold 3 is closed, the hook teeth 521 of the buckle 52 and the hook teeth 521 of the L-shaped gusset plate 6 are just completely in contact with each other, and one side of the hook teeth 521 of the L-shaped gusset plate 6 is in contact with the inner wall of the U-shaped frame 51. The length of the hook teeth 521 of the buckle 52 is shorter than the length of the buckle 52, which can facilitate the separation of the two hook teeth 521. Because the lower ice hockey mold 3 is separated from the upper ice hockey mold 3 by rotation rather than vertical separation, when the hook teeth 521 of the L-shaped gusset plate 6 moves, it will also apply an oblique force to the hook teeth 521 of the buckle 52 to facilitate the separation of the two.

[0034] A middle partition 56 is fixed in the middle of the U-shaped frame 51. When the lower ice hockey mold 3 is closed, the surface of the L-shaped buckle plate 6 will abut against the middle partition 56. The lower end of the middle partition 56 is located on one side of the L-shaped buckle plate 6 and is provided with a chamfered angle to facilitate the L-shaped buckle plate 6 to enter the U-shaped frame 51. A groove is provided in the middle of the upper end of the middle partition 56. An L-shaped head 59 is hinged in the groove to separate the two hook teeth 521. A second connecting rod 58 is fixed at one end of the L-shaped head 59 away from the buckle 52. A first connecting rod 57 is hinged at one end of the second connecting rod 58 away from the buckle 52. The first connecting rod 57 and the second connecting rod 58 have an included angle (such as Figure 6 As shown in FIG. 1 , one end of the connecting rod 1 57 away from the connecting rod 2 58 is hinged to the slot in the middle of the buckle 52. It should be noted that there should be no virtual position at the above connection, otherwise the linkage accuracy between the L-shaped head 59 and the buckle 52 will be reduced, and the lower ice hockey mold 3 and the lower ice hockey mold 3 cannot be separated as required, affecting the use of the device.

[0035] The buckle 52 is located on both sides of the inner cavity of the U-shaped frame 51 and on both sides of the inner wall of the inner cavity of the U-shaped frame 51, rectangular grooves 55 are opened, every two rectangular grooves 55 correspond to each other and a fixing seat 54 is hinged inside the rectangular groove 55, and a circular groove is opened in the middle of each fixing seat 54, and a spring 53 is fixed between the circular grooves of the two corresponding fixing seats 54, and the circular groove fits the spring 53 exactly and is fixed by glue or installing the buckle 52. Under normal circumstances, the buckle 52 is parallel to the inner wall of the U-shaped frame 51 under the push of the two springs 53, and the surface of the spring 53 is electroplated with an anti-corrosion coating to prevent the spring 53 from being corroded.

[0036] Among them, the device also includes an ice maker body, which has the same function buttons as the existing ice maker, and will not be described in detail one by one. The lower ice ball mold 3 and the inner wall of the lower ice ball mold 3 are fixed with silicone. This technology is the existing technology and will not be described in detail. It should be noted that the silicone of the lower ice ball mold 3 and the silicone of the lower ice ball mold 3 both protrude from the lower ice ball mold 3 and the end face of the lower ice ball mold 3 by 0.5MM, so that the gap can be better filled when the lower ice ball mold 3 and the lower ice ball mold 3 are abutted and closed.

[0037] The hinges used in this device are all connected via a rotating shaft, which is a well-known technology and the specific connection method will not be described in detail.

[0038] Principle and process of this utility model:

[0039] Before making ice:

[0040] When the user turns on the power of the ice maker, the driving mechanism 2 drives the lower ice ball mold 3 to rotate, thereby inserting the two L-shaped buckle plates 6 into the U-shaped frame 51. The insertion process is as follows: the lower ice ball mold 3 drives the L-shaped buckle plate 6 and the hook teeth 521 to slowly enter the U-shaped frame 51. At the same time, the L-shaped buckle plate 6 moves closely against the surface of the middle partition plate 56 to achieve a limiting effect. Subsequently, one end of the hook tooth 521 of the L-shaped buckle plate 6 will contact the hook tooth 521 of the buckle 52 first. Because the upper ends of the hook teeth 521 of the L-shaped buckle plate 6 and the hook teeth 521 of the buckle 52 are both inclined surfaces, the hook teeth 521 of the L-shaped buckle plate 6 will squeeze the hook teeth 521 of the buckle 52 to rotate the buckle 52 until the hook teeth 521 of the L-shaped buckle plate 6 are completely abutted against the hook teeth 521 of the buckle 52, thereby splicing the lower ice ball mold 3 with the upper ice ball mold 3 into a sphere and achieving sealing, thereby achieving ice making.

[0041] When the buckle 52 rotates, it will squeeze the spring 53 through the fixing seat 54. When the hook tooth 521 of the L-shaped buckle plate 6 is located at the upper end wall of the hook tooth 521 of the buckle 52 and abuts and closes, the L-shaped head 59 abuts against the inclined surface 2 523 at the upper end of the hook tooth 521 of the L-shaped buckle plate 6, and the buckle 52 returns to its original position under the reaction force of the spring 53, so that the hook tooth 521 of the buckle 52 supports the hook tooth 521 of the L-shaped buckle plate 6. At this time, the driving mechanism 2 can be powered off. This setting adopts a mechanical structure to limit the lower ice ball mold 3 and the upper ice ball mold 4 will not separate even if ice is made for a long time, water expands into ice, and under the action of the gravity of ice, a firm fixing effect is achieved. The lower ice ball mold 3 and the upper ice ball mold 4 will not separate, so there will be no gap in the silicone joint between the two, which will cause the surface of the ice ball to be not smooth enough.

[0042] After ice making is completed: the driving mechanism 2 is powered on and rotates in the reverse direction, thereby driving the lower ice ball mold 3 to move. During the movement, the hook tooth 521 of the L-shaped buckle plate 6 pushes the hook tooth 521 of the buckle 52. At the same time, the L-shaped head 59 provided will move on the inclined surface 2 523 at the upper end of the hook tooth 521 of the L-shaped buckle plate 6. Since the inclined surface 2 523 is inclined, the inclined surface 2 523 will push the L-shaped head 59 to rotate around the rotating shaft. By using the principle of leverage, the other end of the L-shaped head 59 is driven downward by driving the second connecting rod 58 downward, and the second connecting rod 58 drives the first connecting rod 57 downward through the rotating shaft. The connecting rod 57 drives the buckle 52 to rotate around the shaft through the shaft, so that the hook tooth 521 at the lower end of the buckle 52 slides on the surface of the hook tooth 521 of the L-shaped buckle plate 6 and separates, so that the ice ball falls into the lower ice ball mold 3 under the action of gravity, and the lower ice ball mold 3 is separated from the upper ice ball mold 4. At the same time, when the hook tooth 521 at the lower end of the buckle 52 is separated from the hook tooth 521 of the L-shaped buckle plate 6, the buckle 52 will compress the spring 53 through the fixing seat 54. The spring 53 is inclined, which can better match the rotation of the buckle 52 and avoid uneven force on the spring 53.

[0043] Subsequently, the manufactured ice ball will be released from the lower ice ball mold 3 and then fall into the collection box inside the refrigeration chamber 7 .
