Description

Technical Field

[0001] This utility model relates to the field of ice makers, and in particular to an ice maker with a quick-change mold. Background Technology

[0002] An ice maker is a device that uses a refrigeration system to cool water to below its freezing point to produce ice. It is widely used in catering, hotels, medical facilities, food processing, and supermarkets. Existing ice makers typically include a refrigeration system, a water supply system, an evaporator (mold), and an ice-removing mechanism. Its workflow generally includes steps such as water injection, refrigeration, ice removal, and ice storage.

[0003] Currently, the core component of most ice makers on the market—the ice mold (evaporator)—is usually fixed inside the equipment. When different shapes (such as square ice, crescent ice, spherical ice, etc.) or different sizes of ice cubes are needed, the entire mold assembly must be replaced. This operation is cumbersome and usually requires professional technicians to use special tools. It is not only time-consuming and labor-intensive, but also seriously affects the continuous operation efficiency of the equipment, which is extremely inconvenient, especially for catering and other occasions that need to flexibly meet different ice needs. Summary of the Invention

[0004] The purpose of this invention is to provide an ice maker with a quick-change mold. It has a clever structure that enables rapid and efficient mold replacement, making it convenient and practical.

[0005] The technical solution to achieve the purpose of this utility model is as follows: This utility model provides an ice maker with a quick-change mold, comprising a casing and a body installed inside the casing. The body contains an ice-making chamber, and the body has a cover that allows the ice-making chamber to be opened. Between the body and the casing are a compressor, a condenser, an expansion valve, a water tank, and an evaporator installed within the body. The ice-making chamber contains a mold that works with the evaporator to make ice. The body also contains a control component for installing and connecting to the mold and controlling its descent and tilting to release ice. The control component includes side rails positioned relative to each other within the ice-making chamber, a drive motor fixed to the body, side sliders slidably positioned within the side rails under the drive of the drive motor, rotary motors fixed to each side slider, plug-in blocks at the output ends of each rotary motor, and detachable connecting rods installed on both sides of the mold. Each connecting rod includes a connecting part for connecting to the mold, a connecting rod part, and a plug-in part fixed to the connecting rod part and perpendicular to it. The bottom of each plug-in part... The device includes a first insertion block, and each insertion rod portion is further provided with a limiting block and a second insertion block slidably disposed between the limiting block and the first insertion block. The first insertion block has a bottom arc surface and a top stop surface, and the second insertion block has a top arc surface and a bottom stop surface. Each insertion block has a slot corresponding to each insertion rod portion. The inner wall of each slot has opposing side grooves. A locking block is slidably disposed within each side groove. A return spring is disposed between the locking block and the bottom of the side groove. The two ends of the return spring act on the locking block and the side groove respectively. Each has a guide arc surface. The distance from the limiting block to the bottom of the insertion rod is less than the distance from the locking block to the bottom of the slot. The connecting rod passes over each locking block through the cooperation of the bottom arc surface and the guide arc surface on the first insertion block, and is connected to the insertion block after being limited and pressed by the top stop surface and the bottom surface of the locking block. The second insertion block passes over each locking block through the pressure of the limiting block, and is connected to the first insertion block through the locking member after being pressed by the top stop surface and the bottom stop surface. After being connected, the first and second insertion blocks are disengaged from the slot through the cooperation of the top arc surface and the locking block.

[0006] Furthermore, the diameter of the first insert is smaller than that of the second insert. Multiple positioning slots are provided on the bottom stop surface, and each positioning slot is provided with a connecting magnetic block. Positioning inserts that are adapted to each positioning slot are provided on the top stop surface, and each positioning insert is provided with a positioning magnetic block. The first insert and the second insert are fixedly connected by the insertion and engagement of each positioning insert and the positioning slot, and by the magnetic attraction of each connecting magnetic block and the positioning magnetic block.

[0007] Furthermore, the mold has side insert rods on both sides, and the connecting part has side insertion holes corresponding to each side insert rod. Each connecting rod is detachably and fixedly connected to the mold through the insertion and engagement of each side insert rod and the side insertion hole.

[0008] Furthermore, the output end of each of the aforementioned drive motors is provided with a first transmission gear, which is disposed within a side slide rail. Each side slide rail is provided with a transmission screw, and the transmission screw is provided with a second transmission gear that can drive and cooperate with the first transmission gear. The side slider is provided with a transmission screw hole that is adapted to each transmission screw. The side slider is slidably disposed within the side slide rail through the drive motor's transmission of the first transmission gear, the transmission cooperation between the first and second transmission gears, and the threaded cooperation between the transmission screw and the transmission screw hole.

[0009] Furthermore, the aforementioned body has an opening on its side, and the casing has a through groove corresponding to the opening. The body has a receiving box for receiving ice blocks. The receiving box passes through the opening and the through groove and extends into the ice-making chamber. The outer wall of the receiving box overlaps with the outer wall of the casing after the receiving box is fully inserted into the ice-making chamber.

[0010] Furthermore, both the receiving box and the cover plate are equipped with gripping parts.

[0011] This utility model has the following positive effects: (1) By setting up a control component consisting of a drive motor, a side slider, a rotating motor, and specially designed plug-in blocks and connecting rods, this utility model realizes the automation, quick replacement, and precise control of the mold. The cooperation between the drive motor and the side slider can automatically control the lifting and lowering of the mold. The rotating motor can control the mold to flip and drop the ice through the plug-in blocks, which greatly improves the efficiency of ice making and ice dropping and reduces manual operation. The unique cooperation structure between the connecting rod and the plug-in block realizes locking and releasing. When inserted, the bottom arc surface and the guide arc surface can easily pass over the locking block, and the top stop surface presses against the bottom surface of the locking block to ensure a firm connection and withstand the torque of flipping and dropping the ice. When replacement is needed, the first and second insert blocks are pressed together, and during the pulling process, the second insert block drives the first insert block to be pulled out of the slot, thereby realizing the quick disassembly and installation of the mold. This effectively solves the problem of the cumbersome mold replacement in the existing technology. The reasonable layout within the reasonable space of the machine body greatly improves the efficiency of mold replacement. The structure is ingenious, convenient and practical.

[0012] (2) This utility model provides physical alignment and shear resistance through the cooperation of the positioning plug and the positioning slot; through the magnetic attraction of the connecting magnetic block and the positioning magnetic block, it can automatically guide and align the connection position, making the combination process of the first plug and the second plug simpler, faster and more accurate, and the connection is more stable, preventing accidental loosening under vibration or force. In addition, by setting the diameter of the first plug to be smaller than the diameter of the second plug, it can avoid the locking block separating the first plug and the second plug during the process of the second plug pulling out the first plug, ensuring the integrity of the first plug and the second plug when they are separated, which is convenient and practical.

[0013] (3) This utility model achieves a detachable connection between the connecting rod and the mold through the cooperation of each side rod and side hole, which makes it easy to replace various types of molds. It has good adjustability and applicability, and is stable and practical.

[0014] (4) By setting the first transmission gear and the second transmission gear, this utility model ensures the stable rotation of the transmission screw. At the same time, the transmission screw can reliably lock the position of the side slider, preventing the mold from sliding down by itself under the action of gravity, thus ensuring the safety and reliability of the working process.

[0015] (5) By setting up a receiving box, the present invention can make it convenient for operators to take ice blocks from the side. At the same time, the receiving box can also be kept flat with the machine casing when not in use, thereby ensuring the clean and beautiful appearance of the whole machine and greatly reducing the impact of the external environment on the ice blocks, which is efficient and convenient.

[0016] (6) By setting a gripping part, this utility model can provide the user with a point of force, making it convenient for the user to pull out the receiving box to take out ice, and also convenient to open and close the cover, which is convenient and practical. Attached Figure Description

[0023] Both the receiving box 3 and the cover plate 4 are provided with gripping parts 5.

[0024] The working principle of this utility model is as follows: During use, the compressor compresses the low-temperature, low-pressure refrigerant gas into a high-temperature, high-pressure gas. The condenser cools and liquefies the high-temperature, high-pressure refrigerant gas into a high-pressure liquid. The coolant passes through the expansion valve to form a low-temperature, low-pressure liquid, which then cools the water inside the mold 7 through the evaporator. During the installation of the mold 7, the connecting rod 66 connects to the mold 7 through the insertion of the side rod 71 and the side insertion hole 660. During the connection between the connecting rod 66 and the insertion block 65, the connecting rod... After the rod 66 passes through each locking block 653 through the cooperation of the bottom arc surface 681 and the guide arc surface 655 on the first insert block 68, it is connected to the insert block 65 after being limited and pressed by the top stop surface 682 and the bottom surface of the locking block 653. The mold 7 is suspended in the refrigeration chamber after being limited and pressed by the top stop surface 682 and the bottom surface of the locking block 653. After the water in the mold 7 is turned into ice cubes by the evaporator, the drive motor 62 drives the first transmission gear 621 to rotate. The transmission screw 67 is connected to the first transmission gear 621 and the second transmission gear 67. The transmission mechanism 1 rotates, and through the engagement of the transmission screw 67 and the transmission screw hole 631, it drives the side slider 63 to slide within the side slide rail 61, thereby causing the mold 7 to descend. After the mold 7 descends above the receiving box 3, the rotary motor drives the insertion block 65 to rotate, thus pouring the ice from the mold 7 into the receiving box 3. The user can then remove the receiving box 3 to retrieve the ice. When changing the mold, the user can lift the mold 7, and the second insertion block 69 will pass over each locking block 653 and then through each positioning insertion block 66. The insertion and engagement of 83 and positioning slot 693, as well as the magnetic attraction of each connecting magnetic block 694 and positioning magnetic block 684, are connected to the first insert block 68. Then, as the mold 7 falls under its own weight, the second insert block 69 pulls out the first insert block 68, thereby separating the mold 7 from the connecting rod 66. This effectively solves the problem of the cumbersome disassembly of the mold 7 in the prior art, greatly improves the efficiency of mold 7 installation and disassembly, and can also be used for the quick installation and disassembly of various different molds 7. The structure is ingenious, convenient and practical.
