Description

Technical Field

[0001] The utility model relates to the technical field of ice making machines, in particular to an ice making mechanism and an ice making machine. Background Art

[0002] There are ice machines for making transparent spherical ice on the market. Since spherical ice cubes are different from square ice cubes, spherical ice cubes need to be set up with an upper hemisphere and a lower hemisphere when making ice cubes. The two hemispheres are combined to form a spherical ice-making space, and generally only one of the upper and lower hemispheres is provided with an evaporator; when removing ice, the hemisphere provided with the evaporator melts the ice through the heat generated by the evaporator, and the spherical ice cubes can quickly detach from the hemisphere; however, it is more difficult to remove ice from the other hemisphere without the evaporator, resulting in low ice-making efficiency of the entire machine.

[0003] In order to solve the technical problem of ice removal difficulty, the invention patent with publication number CN102878744A discloses an ice maker, including a tray component, which includes an upper tray with an upper ice tray and a lower tray with a lower ice tray, the lower ice tray is tightly attached to the upper ice tray to form a spherical ice tray; a driving unit, which is arranged on one side of the tray component and is used to provide power, and the power is used to separate one of the upper tray and the lower tray from the other; an ejection unit, which is arranged on one side of the tray component and is used to separate ice cubes formed inside the spherical ice tray; one of the upper tray and the lower tray is linearly moved in the up and down directions by the driving unit. When de-icing in the prior art, the upper plate tray and the lower plate tray are first separated by a driving unit to perform a primary peeling of the spherical ice cubes, and then the spherical ice cubes inside the spherical ice tray are secondarily peeled off by two ejection units that can move up and down, thereby realizing mechanical peeling of the spherical ice cubes; however, the ejection unit structure of the prior art is very complicated and the cost is very high, and the spherical ice cubes are peeled off multiple times by a mechanical method, which is easy to cause damage to the spherical ice cubes. Although the efficiency of the entire ice machine can be improved, the yield rate of the spherical ice cubes is not high.

[0004] Therefore, there is still room for improvement and development in the existing technology. Utility Model Content

[0005] In view of the problems in the prior art, the utility model provides an ice-making mechanism and an ice-making machine, which adopt a heat exchange and ice-melting method to achieve the de-icing effect of spherical ice cubes without causing damage to the spherical ice cubes. This not only improves the ice-making efficiency of the entire machine, but also improves the yield rate of spherical ice cubes. The structure is simpler and the cost is lower.

[0006] In order to achieve the above purpose, the technical solution applied by the utility model is as follows:

[0007] An ice-making mechanism comprises an evaporator upper mold assembly, on which a heat-conducting assembly and an upper hemispherical ice tray are arranged, and the heat-conducting assembly and the upper hemispherical ice tray are arranged correspondingly; an evaporator lower mold assembly, on which a lower hemispherical ice tray is arranged, and the evaporator lower mold assembly can be rotatably connected to the evaporator upper mold assembly through a rotating assembly, and the inner cavity of the lower hemispherical ice tray cooperates with the inner cavity of the upper hemispherical ice tray to form a spherical ice-making tray; an ice-making water circuit, which is connected to the inner cavity of the lower hemispherical ice tray; and an ice-de-icing water circuit, which is arranged correspondingly to the outer side of the lower hemispherical ice tray. With this arrangement, when making ice, the rotating component works to drive the evaporator lower mold component and the evaporator upper mold component to be tightly attached to form a spherical ice grid, and water is supplied to the spherical ice grid through the ice-making water circuit. At the same time, the ice maker transfers the cold energy to the spherical ice grid to achieve ice making; when removing ice, the reversing valve of the ice maker works to transfer heat to the heat-conducting component, so that the contact surface between the spherical ice cubes and the upper hemisphere ice grid is melted, thereby achieving the detachment of the spherical ice cubes from the upper hemisphere ice grid; it should be noted that since the lower hemisphere ice grid does not have a heat-conducting component and the lower hemisphere ice grid is far away from the heat-conducting component, it takes a long time for heat to be transferred from the heat-conducting component to the lower hemisphere ice grid. At this time, the spherical ice cubes will stick to the lower hemisphere ice grid, and the rotating component works to drive the evaporator lower mold component to separate from the evaporator upper mold component, and the ice-removing water circuit is used to flush and exchange heat on the outside of the lower hemisphere ice grid, so that the contact surface between the spherical ice cubes and the lower hemisphere ice grid is melted, and the spherical ice cubes fall off. Compared with the prior art, the utility model adopts a heat exchange ice melting method to achieve the de-icing effect of spherical ice cubes without causing damage to the spherical ice cubes. It not only improves the ice-making efficiency of the whole machine, but also improves the yield rate of spherical ice cubes. It also has a simpler structure and lower cost.

[0008] According to the above scheme, the de-icing water circuit includes a water tank, a second water pump, a flushing pipe, and a flushing channel arranged in the lower mold assembly of the evaporator and corresponding to the outer side of the lower hemisphere ice tray. The two ends of the flushing channel are respectively provided with a channel inlet and a channel outlet; the water inlet end of the second water pump is connected to the water tank, the water outlet end of the second water pump is connected to the water inlet of the flushing pipe, and the water outlet of the flushing pipe is arranged corresponding to the channel inlet. In this arrangement, when de-icing, the water in the water tank is pumped out by the second water pump, and sent to the flushing channel through the water outlet of the flushing pipe and the channel inlet, so as to flush and exchange heat with the outer side of the lower hemisphere ice tray.

[0009] According to the above scheme, the lower mold assembly of the evaporator includes a hollow hemisphere and a shell, the hollow hemisphere is fixed to one end of the shell, the other end of the shell is open, the inner cavity of the hollow hemisphere forms a lower hemisphere ice tray, and a flushing channel is formed between the outer wall of the hollow hemisphere and the inner wall of the shell. This arrangement has a simple structure, and the other end of the shell is set as an opening, which facilitates the water sprayed from the water outlet of the flushing pipe to be sent into the flushing channel through the opening of the shell and the channel inlet.

[0010] According to the above scheme, the ice-making water circuit includes a water tank, a water pump 1 and a spray pipe, the water inlet end of the water pump 1 is connected to the water tank, the water outlet end of the water pump 1 is connected to the water inlet of the spray pipe, and the water outlet of the spray pipe is connected to the inner cavity of the lower hemisphere ice grid. In this arrangement, when making ice, the water in the water tank is pumped out by the water pump 1 and sent into the spherical ice grid through the spray pipe. In actual application, the spray pipe is located at the center position of the outer wall of the lower hemisphere ice grid, and the water outlet of the flushing pipe is located on the side just below the center position of the outer wall of the lower hemisphere ice grid, so that the conflict between the flushing pipe outlet and the spray pipe in position can be avoided; preferably, the distance from the central axis of the flushing pipe outlet to the center line of the outer wall of the lower hemisphere ice grid is less than one-third of the radius of the lower hemisphere ice grid, so that the water flow from the flushing pipe outlet can flush more area while avoiding the spray pipe.

[0011] According to the above scheme, the flushing pipe of the de-icing water circuit is fixed on the water tank of the ice-making water circuit, the water inlet of the flushing pipe is connected to the water outlet of the second water pump, and the water outlet of the flushing pipe is located in the water tank and below the inlet of the flow channel. With this arrangement, when making ice, the water in the water tank will continuously circulate between the water tank and the spherical ice-making grid under the action of the first water pump. Since part of the water will freeze into ice, the water in the water tank will decrease over time. In order to meet the needs of multiple ice making, it is necessary to add water from the water tank to the water tank in time. When the amount of water in the water tank is insufficient, the second water pump works, and the water flows through the water pump, along the hose to the water outlet of the flushing pipe and enters the water tank, or sprays to the lower hemisphere ice grid, and then falls back into the water tank, thus completing the water adding action. It should be noted that when making ice, the evaporator lower mold assembly is in close contact with the evaporator upper mold assembly, the flow channel outlet of the flushing channel will be blocked by the evaporator upper mold assembly, and the water flows along the hose to the water outlet of the flushing pipe and sprays onto the lower hemisphere ice grid. Since the flow channel outlet is blocked, the water will fall back into the water tank.

[0012] According to the above solution, the water tank is provided with an overflow hole, and the height of the overflow hole is lower than the water outlet of the flushing pipe. This arrangement can prevent the water in the water tank from entering the flushing pipe, and at the same time, the overflow hole can ensure that the amount of ice making water is equal in each round of ice making. When the water reaches the overflow hole, the excess water will flow back to the water tank.

[0013] According to the above scheme, the evaporator lower mold assembly is fixedly connected to the water tank opening of the ice-making water circuit, and the water tank can be rotatably arranged in the water tank of the de-icing water circuit through the rotating assembly. The water tank is provided with an ice receiving basket, and the water tank of the ice-making water circuit is arranged in the water tank of the de-icing water circuit and is located above the ice receiving basket. In this arrangement, when de-icing, the water tank and the evaporator lower mold assembly rotate synchronously under the action of the rotating assembly, and the spherical ice cubes will fall downward to the ice receiving basket in the water tank under the action of gravity, and the water in the water tank will fall back into the water tank.

[0014] According to the above scheme, the rotating assembly includes a rotating shaft and a driving assembly, the evaporator upper mold assembly is fixedly connected to the rotating shaft, the evaporator lower mold assembly is hinged to the rotating shaft, and the evaporator lower mold assembly is driven by the driving assembly to rotate relative to the rotating shaft. In this way, the evaporator lower mold assembly and the water tank can rotate around the rotating shaft by the driving assembly.

[0015] According to the above scheme, the rotation angle of the evaporator lower mold assembly relative to the evaporator upper mold assembly is 0-90 degrees; when the rotation angle of the evaporator lower mold assembly relative to the evaporator upper mold assembly is 0 degrees, the evaporator lower mold assembly is tightly attached to the evaporator upper mold assembly for ice making; when the rotation angle of the evaporator lower mold assembly relative to the evaporator upper mold assembly is 90 degrees, it is used for ice removal. In this way, when ice is removed, the driving component drives the evaporator lower mold assembly to rotate at an angle of 90 degrees relative to the evaporator upper mold assembly, that is, close to a vertical state, and the spherical ice cubes will fall downward under the action of gravity.

[0016] An ice maker includes a machine body, a refrigeration assembly and the above-mentioned ice making mechanism are arranged on the machine body, and the refrigeration assembly is connected to the heat conduction assembly on the evaporator upper mold assembly through a pipeline. In this arrangement, the refrigeration assembly transfers cold or heat to the heat conduction assembly to achieve ice making and ice removal.

[0017] Beneficial effects of the utility model:

[0018] The utility model is configured in this way, and the spherical ice cubes are de-iced by melting ice, which will not cause damage to the spherical ice cubes, thereby improving the efficiency of the entire ice machine and the yield rate of the spherical ice cubes, and the structure is simpler and the cost is lower.

[0027] The technical solution of the utility model is described below in conjunction with the accompanying drawings and embodiments.

In this way, when making ice, the rotating assembly drives the evaporator lower mold assembly 2 and the evaporator upper mold assembly 1 to form a spherical ice grid, and water is supplied to the spherical ice grid through the ice-making water circuit. At the same time, the ice maker transfers the cold energy to the spherical ice grid to realize ice making; when removing ice, the reversing valve of the ice maker works to transfer heat to the heat-conducting assembly 5, so that the contact surface between the spherical ice cube and the upper hemispherical ice grid 3 melts, and the spherical ice cube is separated from the upper hemispherical ice grid 3; it should be noted that due to the lower The hemispherical ice tray 4 does not have a heat conducting component 5, and the lower hemispherical ice tray 4 is far away from the heat conducting component 5. It takes a long time for heat to be transferred from the heat conducting component 5 to the lower hemispherical ice tray 4. At this time, the spherical ice cubes will stick to the lower hemispherical ice tray 4. The rotating component drives the evaporator lower mold component 2 to separate from the evaporator upper mold component 1, and the outer side of the lower hemispherical ice tray 4 is flushed and heat is exchanged by the de-icing water channel, so that the contact surface between the spherical ice cubes and the lower hemispherical ice tray 4 melts, and the spherical ice cubes fall off. Compared with the prior art, the utility model adopts a heat exchange and ice melting method to achieve the de-icing effect of the spherical ice cubes, which will not cause damage to the spherical ice cubes, which not only improves the ice making efficiency of the whole machine, but also improves the yield rate of the spherical ice cubes, and has a simpler structure and lower cost.

[0029] In this embodiment, the de-icing water circuit includes a water tank 15, a second water pump 14, a flushing pipe 12, and a flushing channel 22 provided in the evaporator lower mold assembly 2 and corresponding to the outer side of the lower hemisphere ice tray 4. The two ends of the flushing channel 22 are respectively provided with a channel inlet 23 and a channel outlet 24; the water inlet end of the second water pump 14 is connected to the water tank 15, the water outlet end of the second water pump 14 is connected to the water inlet of the flushing pipe 12, and the water outlet of the flushing pipe 12 is provided corresponding to the channel inlet 23. In this arrangement, when de-icing, the water in the water tank 15 is pumped out by the second water pump 14, and sent to the flushing channel 22 through the water outlet of the flushing pipe 12 and the channel inlet 23, so as to flush and exchange heat with the outer side of the lower hemisphere ice tray 4.

[0030] In this embodiment, the evaporator lower mold assembly 2 includes a hollow hemispherical body 20 and a shell 21. The hollow hemispherical body 20 is fixed to one end of the shell 21, and the other end of the shell 21 is open. The inner cavity of the hollow hemispherical body 20 forms the lower hemispherical ice tray 4, and a flushing channel 22 is formed between the outer wall of the hollow hemispherical body 20 and the inner wall of the shell 21. This arrangement has a simple structure, and the other end of the shell 21 is set to be open, so that the water sprayed from the water outlet of the flushing pipe 12 is sent into the flushing channel 22 through the opening of the shell 21 and the channel inlet 23.

The water inlet end of the water pump 8 is connected to the water tank 11, the water outlet end of the water pump 8 is connected to the water inlet of the spray pipe 10, and the water outlet of the spray pipe 10 is connected to the inner cavity of the lower hemispherical ice tray 4. In this arrangement, when making ice, the water in the water tank 11 is pumped out by the water pump 8 and sent to the spherical ice tray through the spray pipe 10. In actual applications, the spray pipe 10 is located at the center of the outer wall of the lower hemisphere ice tray 4, and the water outlet of the flushing pipe 12 is located on the side just below the center of the outer wall of the lower hemisphere ice tray 4, so that the conflict between the water outlet of the flushing pipe 12 and the spray pipe 10 can be avoided; preferably, the distance from the center axis of the water outlet of the flushing pipe 12 to the center line of the outer wall of the lower hemisphere ice tray 4 is less than one third of the radius of the lower hemisphere ice tray 4, so that the water flow from the water outlet of the flushing pipe 12 can flush a larger area while avoiding the spray pipe 10.

Since part of the water will freeze into ice, the water in the water tank 11 will decrease over time. In order to meet the needs of multiple ice making, it is necessary to add water from the water tank 15 to the water tank 11 in time. When the amount of water in the water tank 11 is insufficient, the water pump 14 works, and the water flows through the water pump, along the hose to the water outlet of the flushing pipe 12 and enters the water tank 11, or sprays to the lower hemisphere ice grid 4, and then falls back to the water tank 11, so that the water adding action is completed. It should be noted that when making ice, the evaporator lower mold assembly 2 is in close contact with the evaporator upper mold assembly 1, the flow channel outlet 24 of the flushing flow channel 22 will be blocked by the evaporator upper mold assembly 1, and the water flows along the hose to the water outlet of the flushing pipe 12 and sprays to the lower hemisphere ice grid 4. Since the flow channel outlet 24 is blocked, the water will fall back into the water tank 11. More specifically, the defrosting water path can be used to flush the outer side of the lower hemisphere ice grid 4 during defrosting, and can also be used to add water when the water tank 11 is short of water.

[0033] In this embodiment, the water tank 11 is provided with an overflow hole, and the height of the overflow hole is lower than the water outlet of the flushing pipe 12. This arrangement can prevent the water in the water tank 11 from entering the flushing pipe 12, and the overflow hole can ensure that the amount of ice making water is equal in each round of ice making. When the water reaches the overflow hole, the excess water will flow back into the water tank 15.
