Description

Technical Field

[0001] The utility model relates to the technical field of ice-making equipment, in particular to an ice-making device capable of automatically lifting and turning over. Background Art

[0002] As a simple cold drink and sprinkles additive, ice machine is easy to make, has a beautiful appearance, increases taste and improves the quality of life, and is becoming more and more popular in the market.

[0003] Existing flip demolding systems use a motor to drive the upper mold vertically upward. During this rise, an ice pusher is inserted through the water inlet hole to push any ice still stuck in the upper mold into the lower mold. After the rise is complete, a controller sends an ice removal command to the flip mechanism, activating the flip motor, which drives the flip shaft and control arm to flip, thereby flipping the lower mold and removing the ice. This ice removal process is cumbersome and inefficient, and requires multiple drive mechanisms, resulting in high costs. Utility Model Content

[0004] In order to solve the technical defects mentioned in the above background technology, the purpose of the present invention is to provide an ice-making device with automatic lifting and turning.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] An ice-making device with automatic lifting and turning, comprising:

[0007] an upper mold, wherein the upper mold is provided with an upper cavity;

[0008] A lower mold, wherein the lower mold is provided with a lower chamber relative to the upper chamber, and the lower mold is buckled and connected with the upper mold so that the upper chamber and the lower chamber enclose an ice-making chamber;

[0009] A lifting device, comprising a lifting motor and a connecting rod assembly; an output shaft of the lifting motor is connected to one end of the connecting rod assembly to drive the connecting rod assembly to move up and down;

[0010] A flipping device, the flipping device includes a movable base plate, a flip bracket and an abutment block; one side of the movable base plate is connected to the other end of the connecting rod assembly, and the flip bracket is erected on one side of the connecting rod assembly; the lower mold is rotatably arranged on the other side of the movable base plate, and the abutment block is arranged on one side of the lower mold relative to the upper side of the flip bracket; when the movable base plate descends to the set position, the abutment block and the lower mold rotate at a set angle to facilitate ice removal, and the abutment block is in contact with the flip bracket.

[0011] By adopting the above technical solution, the lower mold and the upper mold are interlocked to form an ice-making chamber enclosed by the upper and lower chambers. The lifting motor drives the movable base, the abutment block, the lower mold, and the ice cubes formed therein toward the flip bracket through a connecting rod assembly. When the movable base descends to a certain position, the abutment block contacts and connects with the end of the flip bracket. As the movable base continues to descend, the force of the flip bracket pushes the abutment block and the lower mold to rotate around the movable base. When the rotation reaches the set angle, the ice cubes in the lower chamber fall out, completing the automatic demolding of the ice cubes. The reversing lifting motor can drive the movable base, the abutment block, and the lower mold to rise together. When the abutment block separates from the flip bracket, the flip bracket removes the force applied to the abutment block, and the abutment block and the lower mold rotate in the opposite direction to return to their initial state. Demolding efficiency is high, and only one lifting motor is required to perform a series of actions such as lifting and flipping. This high transmission efficiency and compact structure also significantly save costs.

[0012] Furthermore, the flip bracket includes a support portion and an abutment portion. The support portion is vertically arranged, one end of the abutment portion is fixedly connected to the support portion, and the abutment portion is arranged to protrude from the support portion. The end of the abutment portion away from the support portion is in contact with the abutment block. During the descent process, the abutment block is subjected to the force exerted by the abutment portion, which drives the lower mold to flip. Flipping does not require the drive of a motor, saving costs, reducing occupied space, and improving work efficiency.

[0013] Furthermore, the abutting portion and one end of the supporting portion are configured as tapered ends, and the tapered inclined surface of the tapered end is in abutment with the end portion of the supporting portion, thereby improving the efficiency of the flipping.

[0014] Furthermore, the flipping device also includes at least one torsion spring, which is arranged on the movable base plate, one end of the torsion spring is in contact with the movable base plate, and the other end of the torsion spring is in contact with the side of the tapered end away from the support portion, thereby improving the efficiency of automatic resetting of the movable base plate and the lower mold, thereby improving production efficiency.

[0015] Furthermore, the movable base plate is provided with an avoidance groove, the lower mold and the abutment block are both arranged in the avoidance groove, and the flip bracket is arranged below the avoidance groove, with a compact structure.

[0016] Furthermore, the lifting device also includes a base plate and a screw rod, the lifting motor is arranged on one side of the base plate, and one end of the screw rod is fixedly connected to the output shaft of the lifting motor. The connecting rod assembly includes two first connecting rods, two second connecting rods, a base plate movable shaft and a top plate. The base plate movable shaft is slidably arranged at the end of the base plate away from the lifting motor, and the other end of the screw rod is connected to the base plate movable shaft. A first connecting rod and a second connecting rod are provided on both sides of the base plate. One end of the first connecting rod is fixedly connected to the end of the base plate close to the lifting motor, and the other end of the first connecting rod is slidably connected to the end of the top plate close to the base plate movable shaft. One end of the second connecting rod is fixedly connected to the base plate movable shaft, and the other end of the second connecting rod is fixedly connected to the end of the top plate close to the lifting motor. The first connecting rod and the second connecting rod on the same side are arranged crosswise. The movable base plate is fixedly connected to the side of the top plate facing away from the base plate. One of the lifting motors drives the first connecting rod and the second connecting rod on both sides to slide through the screw and the bottom plate moving shaft to move the movable base plate, which has higher transmission efficiency, ensures that the lifting operations on both sides are performed synchronously, and improves the lifting stability.

[0017] Furthermore, the lifting device also includes a travel switch, which is arranged on one side of the flip bracket and is used to limit the descending stroke of the movable base plate, thereby improving the control accuracy and work efficiency.

[0018] Furthermore, the upper mold is provided with an open upper chamber, the inner surface of which is covered with a first flexible layer. The upper mold and the lower mold are both made of a rigid material. The lower mold is provided with an open lower chamber, the inner surface of which is covered with a second flexible layer. The upper mold and the lower mold are connected to form a closed ice-making chamber, and the space enclosed by the upper and lower chambers is the ice-making chamber. Evaporators are provided on the outer peripheries of the upper and lower molds for transporting refrigerant.

[0019] Furthermore, the upper mold and the upper chamber are integrally formed, and the lower mold is sleeved inside the upper mold, thereby improving assembly efficiency.

[0020] Furthermore, the automatic lifting and flipping ice-making device also includes a water circulation device, which includes a cold water tank, a circulating water pump, a water suction pipe, a water outlet pipe, and an overflow pipe. The cold water tank is rotatably arranged on the movable base plate, and the lower mold is fixed in the cold water tank. One end of the water suction pipe is located in the cold water tank, and the other end of the water suction pipe is connected to the circulating water pump. One end of the water outlet pipe is connected to the circulating water pump, and the other end of the water outlet pipe is connected to the lower chamber of the lower mold. One end of the overflow pipe is connected to the upper chamber, and the other end of the overflow pipe is bent and arranged in the cold water tank. The circulating water pump draws the water from the cold water tank into the ice-making chamber through the water suction pipe. When the ice-making chamber is full, the water from the water outlet pipe flows back to the cold water tank. Through such a circulation loop, the cold water from the cold water tank circulates continuously in the ice-making chamber, expelling the air in the water during ice-making, producing ice cubes with high transparency, effectively improving ice-making efficiency, reducing ice-making energy consumption, and speeding up ice-making time. During the freezing process in the ice-making chamber, the water at the water inlet begins to freeze. When the ice is formed, the resistance is too great, blocking the water flow, causing the circulating water pump to have an excessive current. The feedback system judges that ice-making is complete through the change in current data.

[0021] In summary, the beneficial effects of the present invention are:

[0022] This utility model features an integrated automatic lifting and flipping ice-making device with a lower mold and upper mold that interlock to form an ice-making chamber. A lifting motor, via a connecting rod assembly, drives a movable base, abutment blocks, the lower mold, and the ice cubes formed therein, toward a flip support. When the movable base descends to a certain position, the abutment blocks contact the end of the flip support. As the movable base continues to descend, the flip support forces the abutment blocks and the lower mold to rotate around the movable base. When the rotation reaches a set angle, the ice cubes in the lower chamber fall out, completing the automatic demolding. The reversing lifting motor drives the movable base, abutment blocks, and lower mold to rise together. When the abutment blocks separate from the flip support, the flip support releases the force applied to the abutment blocks, causing the abutment blocks and the lower mold to rotate in the opposite direction to return to their initial state. This highly efficient demolding mechanism utilizes only one lifting motor to perform the lifting, flipping, and other actions. This results in high transmission efficiency, a compact structure, and significant cost savings. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The following is combined with Figure 1-10 , the embodiments of the utility model are further described in detail.

[0039] An automatic lifting and flipping integrated ice making device 1, such as Figure 1 、 Figure 2 、 Figure 3 As shown, it includes an upper mold 2, a lower mold 3, a lifting device 4, a flipping device 5 and a water circulation device 6. The upper mold 2 is fixedly connected to an external support device, and the upper mold 2 is provided with an upper chamber 21. The lower mold 3 is provided with a lower chamber 31 relative to the upper chamber 21. The lower mold 3 is snap-fitted to the upper mold 2 to form an ice-making chamber enclosed by the upper chamber 21 and the lower chamber 31. The water circulation device 6 is used to drive the water in the ice-making chamber to circulate and discharge the gas in the ice-making chamber. The lower mold 3 is connected to the flipping device 5. When the lifting device 4 drives the lower mold 3 and the flipping device 5 to move, the flipping bracket 52 applies a rotational force to the flipping device 5, causing the lower mold 3 to flip so that the ice product is demolded.

[0040] In this embodiment, please refer to Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 The lifting device 4 includes an upper base plate 41, four support rods 42, a lower base plate 43, a lifting motor 44, a connecting rod assembly 45, a bottom plate 46, a screw 47, and a travel switch 48. The four support rods 42 are arranged in a square pattern. The upper base plate 41 is fixedly connected to one end of the four support rods 42, and the lower base plate 43 is fixedly connected to the other end of the four support rods 42. The upper mold 2 is fixedly connected to the upper base plate 41. During the demolding process, the upper mold 2 is fixed. The bottom plate 46 is fixed to the lower base plate 43. The lifting motor 44 is arranged on one side of the bottom plate 46. The output shaft of the lifting motor 44 is connected to one end of the connecting rod assembly 45 to drive the connecting rod assembly 45 to move up and down.

[0041] Specifically, one end of the screw 47 is fixedly connected to the output shaft of the lifting motor 44. The screw 47 is mounted on the base plate 46, and the motor sleeve 441 is connected and sleeved into one end of the screw 47. The output shaft of the lifting motor 44 is connected to the motor sleeve 441 and fixed to the lower base plate 43.

[0042] The connecting rod assembly 45 includes two first connecting rods 451, two second connecting rods 452, a connecting shaft 453, a bottom plate movable shaft 454, a top plate movable shaft 456, and a top plate 455. The bottom plate movable shaft 454 is slidably mounted on the end of the bottom plate 46 away from the lifting motor 44, and the other end of the screw 47 is connected to the bottom plate movable shaft 454. A first connecting rod 451 and a second connecting rod 452 are disposed on each side of the bottom plate 46. One end of the first connecting rod 451 is fixedly connected to the end of the bottom plate 46 near the lifting motor 44, and the other end of the first connecting rod 451 is slidably connected to the end of the top plate 455 near the bottom plate movable shaft 454. One end of the second connecting rod 452 is fixedly connected to the bottom plate movable shaft 454, and the other end of the second connecting rod 452 is fixedly connected to the end of the top plate 455 near the lifting motor 44. The first connecting rod 451 and the second connecting rod 452 on the same side are arranged crosswise. The other ends of the two first connecting rods 451 are respectively fixedly connected to the two ends of the top plate movable shaft 456, and the top plate movable shaft 456 is slidably connected to the top plate 455. The other ends of the second connecting rods 452 are respectively fixedly connected to the top plate fixed shaft 457, and the top plate fixed shaft 457 is fixedly connected to the end of the top plate 455 away from the top plate movable shaft 456.

[0043] The two intersections are connected by a connecting shaft 453, enhancing movement stability. The movable base plate 51 is fixedly connected to the side of the top plate 455 facing away from the bottom plate 46. A lifting motor 44, via a screw 47 and the bottom plate's movable shaft 454, simultaneously drives the first and second connecting rods 451, 452 on both sides to slide, thereby moving the movable base plate 51. This improves transmission efficiency, ensures synchronous lifting operations on both sides, and improves lifting stability.

[0044] A limit switch 48 is provided on one side of the tilt bracket 52 to limit the travel of the movable base plate 51, thereby improving control accuracy and work efficiency. By integrating the tilt device 5 with the lifting device 4, the lower mold 3 can be tilted and rotated simultaneously with its elevation, achieving tilting, rotation, and reset of the lower mold 3, resulting in a simple and compact structure.

[0045] In this embodiment, please refer to Figure 4 、 Figure 5 、 Figure 6 The flipping device 5 includes a movable base plate 51, a flip bracket 52, at least one torsion spring 53, and an abutment block 54. One side of the movable base plate 51 is connected to the other end of the connecting rod assembly 45, and the flip bracket 52 is erected on one side of the connecting rod assembly 45. The lower mold 3 is rotatably mounted on the other side of the movable base plate 51. An abutment block 54 is positioned on one side of the lower mold 3, above the flip bracket 52. When the movable base plate 51 descends to a set position, the abutment block 54 rotates with the lower mold 3 to a set angle to facilitate ice removal, and the abutment block 54 contacts the flip bracket 52.

[0046] Specifically, the movable base plate 51 passes through four support rods 42, which also guide the movable base plate 51 during the lifting process. The movable base plate 51 is also connected to the top plate 455 via multiple fixing columns 55, which enhance the support force on the movable base plate 51. The movable base plate 51 is provided with a relief groove, in which the lower mold 3 and the abutment block 54 are both positioned. The flip bracket 52 is positioned below the relief groove, resulting in a compact structure.

[0047] The flip bracket 52 includes a support portion 521 and an abutment portion 522. The support portion 521 is vertically disposed, and one end of the abutment portion 522 is fixedly connected to the support portion 521, protruding from the support portion 521. The end of the abutment portion 522, distal from the support portion 521, abuts against an abutment block 54. During the descent process, the abutment block 54, under the force exerted by the abutment portion 522, drives the lower mold 3 to flip. This eliminates the need for a motor to drive the flip, saving costs, reducing occupied space, and improving work efficiency.

[0048] The abutting portion 522 and one end of the supporting portion 521 are configured as tapered ends, and the tapered inclined surface of the tapered end abuts and connects with the end of the supporting portion 521 to improve the efficiency of the flipping.

[0049] Furthermore, the flip bracket 52 and the abutment block 54 are provided in two sets, with one set of flip bracket 52 and abutment block 54 provided on both sides of the movable base plate 51, thereby improving stability and efficiency during the flipping process. Specifically, the abutment block 54 is fixedly mounted on the side of the cold water tank 65 and is arranged horizontally.

[0050] The torsion spring 53 is arranged on the movable base plate 51, one end of the torsion spring 53 is in contact with the movable base plate 51, and the other end of the torsion spring 53 is in contact with the side of the tapered end away from the support portion 521, thereby improving the efficiency of automatic reset of the movable base plate 51 and the lower mold 3, thereby improving production efficiency.

[0051] In this embodiment, please refer to Figure 3 、 Figure 5 、 Figure 8 、 Figure 9 The upper mold 2 has an open upper chamber 21 within it, and the inner surface of the upper chamber 21 is covered with a first flexible layer 22. Both the upper mold 2 and the lower mold 3 are made of a rigid material. The lower mold 3 has an open lower chamber 31 within it, and the inner surface of the lower chamber 31 is covered with a second flexible layer 32. The upper mold 2 and the lower mold 3 are joined together to form a closed ice-making chamber. The space enclosed by the upper chamber 21 and the lower chamber 31 constitutes the ice-making chamber. The flexible layer can be made of a soft material such as silicone.

[0052] In this embodiment, the ice-making chamber is configured as a spherical structure. The specific shape of the ice-making chamber can be selected according to user needs and is not limited here. The upper mold 2 and the upper chamber 21 are integrally formed, and the lower mold 3 is inserted into the upper mold 2, which improves assembly efficiency.

[0053] An evaporator 7 is installed on the outer periphery of the upper and lower molds 2, 3, to transport refrigerant. The evaporator 7 completely surrounds the ice-making cavity formed by the upper and lower molds 2, 3. A sealing ring 34 is installed where the upper and lower molds 2, 3 meet to enhance waterproof sealing. The space formed by the evaporator 7, the ice-making cavity, and the outer shell 24 is filled with a thermal insulation agent 25, which fully utilizes the cooling energy of the evaporator 7, improving ice-making efficiency and accelerating ice-forming time.

[0054] Specifically, the evaporator 7 includes an evaporation tube 71 and a flow channel 72. The outer wall of the upper mold 2 is provided with a spiral groove to form the flow channel 72. Both ends of the spiral groove are connected to the corresponding evaporation tube 71. This increases the effective cooling area, provides more uniform cooling, and effectively improves ice-making efficiency, speeding up ice-making time and enhancing product efficiency. The spiral groove structure is not shown in the figure.

[0055] Alternatively, the flow channel 72 can be provided in the form of a spiral tube. The spiral tube is arranged in a spiral shape and is sleeved around the outer periphery of the upper mold 2 and the lower mold 3. The interior of the spiral tube is hollow to form the flow channel 72, and both ends of the spiral tube are connected to the corresponding evaporation tube 71. This facilitates installation and improves the refrigerant delivery efficiency. The spiral tube is wrapped around the outer periphery of the ice-making chamber. The structure of the spiral tube is not shown in the figure.

[0056] In this embodiment, please refer to Figure 4 、 Figure 5 、 Figure 10 The water circulation device 6 includes a water tank 61, a water pump 62, a water inlet pipe 63, a water pump 64, a cold water tank 65, a circulating water pump 66, a water suction pipe 67, a water outlet pipe 68, and an overflow pipe 69. The water tank 61 is disposed below the tilting device 5. One end of the water pump 64 is connected to the water tank 61, and the other end of the water pump 64 is connected to the water pump 62. One end of the water inlet pipe 63 is connected to one end of the water pump 62, and the other end of the water inlet pipe 63 is connected to the cold water tank 65.

[0057] The cold water tank 65 is rotatably arranged on the movable base plate 51, and the lower mold 3 is fixed in the cold water tank 65. One end of the water suction pipe 67 is located in the cold water tank 65, and the other end of the water suction pipe 67 is connected to the circulating water pump 66. One end of the water outlet pipe 68 is connected to the circulating water pump 66, and the other end of the water outlet pipe 68 is connected to the lower chamber 31 of the lower mold 3. One end of the overflow pipe 69 is connected to the upper chamber 21, and the other end of the overflow pipe 69 is bent and arranged in the cold water tank 65. An overflow hole is provided above or on the side of the upper chamber 21, and the plastic sleeve of the upper mold 2 is installed at the overflow hole. A water outlet is provided below or on the side of the lower chamber 31, and the plastic sleeve 33 of the lower mold is installed at the water outlet hole. The plastic sleeve 33 of the lower mold is connected to the water outlet pipe 68.

[0058] The water supply pipe 64 of the water pump 62 pumps a fixed amount of water from the water storage tank 61 into the cold water tank 65. When the cold water tank 65 reaches the desired level, the water pump 62 stops. A circulating water pump 66 pumps the water from the cold water tank 65 into the lower chamber via a suction pipe 67. The circulating water pump 66 then pumps the water from the cold water tank 65 into the ice-making chamber via a suction pipe 67. When the ice-making chamber is full, the water returns to the cold water tank 65 through an outlet pipe 68. This circulation loop allows the cold water from the cold water tank 65 to continuously circulate within the ice-making chamber, discharging air from the water during ice-making. This produces ice cubes with high transparency, effectively improving ice-making efficiency, reducing energy consumption, and accelerating ice-making time.

[0059] When making ice, water circulates continuously in the ice-making chamber, expelling a large amount of air from the water to produce ice cubes with high transparency. The spherical ice cubes produced are highly transparent, round in shape and beautiful in appearance.

[0060] During the freezing process in the ice making chamber, the water at the water inlet begins to freeze. When the ice is formed, the resistance is too great to block the water flow, causing the circulating water pump 66 to have an excessive current. The feedback system judges that the ice making is completed through the current data change.

[0061] Because the upper mold 2 is provided with a first flexible layer 22 and the lower mold 3 is provided with a second flexible layer 32, when the volume generated by ice formation increases, the deformation of the flexible layer can eliminate the pressure generated by the increase in the volume of ice, and the ice cubes are not easy to break or separate when formed, so that complete ice cubes are produced. Because the surface of the cavity hole is covered with silicone and plastic, it is non-sticky to the formed ice cubes, and the ice cubes are easy to fall off. Due to the small hole diameter, the junction between the hole diameter and the ice cube is easy to break and fall off. The surface of the ice cubes produced is round and smooth, and the appearance is beautiful.

[0062] In this embodiment, the lifting device 4 is not limited to driving the cold water box 65 and the lower mold 3 to move up and down and flip to demould, and can also drive the lower mold 3 to tilt and other achievable methods, which are not limited here.

[0063] The lower mold 3 is joined to the upper mold 2, forming an ice-making chamber enclosed by the upper chamber 21 and the lower chamber 31. The lifting motor 44, via the connecting rod assembly 45, drives the movable base plate 51, the abutment block 54, the lower mold 3, and the finished ice cubes therein, toward the flip bracket 52. When the movable base plate 51 descends to a certain position, the abutment block 54 abuts against the end of the flip bracket 52. As the movable base plate 51 continues to descend, the force of the flip bracket 52 pushes the abutment block 54, the cold water tank 65, and the lower mold 3 to rotate about the movable base plate 51. When the rotation reaches the set angle, the movable base plate 51 simultaneously triggers the limit switch 48, the lower mold 3 stops its downward movement, and the ice cubes in the lower chamber 31 fall out, completing the automatic demolding of the ice cubes.

[0064] By reversing the lifting motor 44 at a predetermined time, the movable base plate 51, the abutment block 54, and the lower mold 3 can be driven to rise together. When the abutment block 54 is separated from the flip bracket 52, the flip bracket 52 cancels the force applied to the abutment block 54, and the abutment block 54 and the lower mold 3 rotate in the opposite direction to return to their initial state. The demolding efficiency is high, and only one set of lifting motors 44 is required to achieve a series of actions such as lifting and flipping. The transmission efficiency is high, the structure is compact, and it also significantly saves costs. The lower mold 3 continues to move upward until it is closed with the upper mold 2, and the next cycle of work begins at a predetermined time. The structure is simple and compact, which reduces the use space and reliably realizes the lifting and flipping functions.

Identical components are represented by the same reference numerals. Therefore, any equivalent changes made based on the structure, shape, and principle of this application should be included in the scope of protection of this application.
