Description

Technical Field

[0001] This utility model relates to the field of evaporator tubes for ice makers, and particularly to evaporator tubes for ice makers that can be quickly installed. Background Technology

[0002] In an ice maker, the evaporator is the core heat exchange component, typically consisting of copper tubes bent into a series loop containing multiple parallel straight tubes and U-shaped bends. The evaporator tubes need to be securely positioned within the ice maker's casing to ensure accurate relative positioning to the ice molds, water tank, or other components, and to withstand stresses from refrigerant pulses, compressor vibrations, and periodic thermal expansion and contraction.

[0003] Traditional installation methods typically involve using individual pipe clamps, cable ties, or welded brackets to fix the straight and curved sections of the evaporator pipe to the support frame one by one. This method has significant drawbacks: First, the installation process is cumbersome, requiring individual operation at each fixing point, resulting in low assembly efficiency. Second, rigid fixing requires high installation precision and is difficult to effectively buffer and absorb vibration and thermal stress. Over time, stress concentration at weld points or bends can lead to fatigue cracks, causing refrigerant leakage and affecting the reliability and lifespan of the ice maker, which is extremely inconvenient. Summary of the Invention

[0004] The purpose of this invention is to provide an ice maker evaporator tube that can be installed quickly. Its ingenious structure allows for rapid installation of the evaporator tube body while simultaneously buffering vibrations generated by the compressor, greatly extending the service life of the evaporator tube body. It is highly efficient and convenient.

[0005] The technical solution to achieve the purpose of this utility model is as follows: This utility model has an evaporator tube body, which includes multiple parallel straight tubes and multiple U-shaped bent tubes, with the straight tubes connected in series by the bent tubes; the evaporator tube body is provided with two positioning devices that are arranged opposite to each other and can position each straight tube and the bent tubes between adjacent straight tubes. The positioning device includes a connecting base rod that can be connected to an ice maker, multiple first clamping blocks that are evenly arranged on the connecting base rod along the extension direction of the connecting base rod and can clamp each straight tube, and multiple positioning components that are arranged between adjacent clamping blocks and can position the bent tubes. The positioning components include positioning sliding holes provided on the connecting base rod, positioning sliding rods that are slidably provided in the positioning sliding holes, and positioning components that are fixed on the positioning sliding rods. The device includes a limiting plate, a first compression spring sleeved on the positioning slide rod, a side support rod fixed on the positioning slide rod, and a second locking block set on the side support rod to clamp the bent pipe. The axis of the positioning slide hole is perpendicular to the extension direction of the connecting bottom rod. The first locking block has a first slot for inserting a straight pipe, and the second locking block has a second slot for inserting a straight pipe. The extension direction of the side support rod is perpendicular to the extension direction of the connecting bottom rod. The two ends of the first compression spring act on the limiting plate and the connecting bottom rod, respectively. Each straight pipe on the evaporator tube body is positioned and connected to the connecting bottom rod by engaging with the first slot on each of the first locking blocks. Each bent pipe is positioned and connected to the side support rod by engaging with the second slot on each of the second locking blocks, the sliding engagement of the positioning slide rod and the positioning slide hole, and the continuous force of the first compression spring.

[0006] Furthermore, each first slot is provided with a first arc-shaped guide surface that can guide a straight pipe into the first slot, and each second slot is provided with a second arc-shaped guide surface that can guide a bent pipe into the second slot.

[0007] Furthermore, the first adjusting groove on the connecting base rod corresponds to each first locking block. The extension direction of the first adjusting groove is parallel to the extension direction of the connecting base rod. Both sides of the first adjusting groove are provided with first side grooves in the same extension direction as the first adjusting groove. The bottom of each first locking block is provided with a first adjusting slider that can be slidably disposed in the first adjusting groove. Both sides of the first adjusting slider are provided with first side rods. Each first side rod is slidably disposed in the corresponding first side groove. Each first side groove is provided with a second compression spring. The two ends of the second compression spring act on the bottom of the first side groove and the first side rod, respectively. The first locking block is adjusted and buffered through the sliding cooperation of the first adjusting slider and the first adjusting groove, the sliding cooperation of each first side rod and the corresponding first side groove, and the continuous force of each second compression spring.

[0008] Furthermore, the aforementioned second block includes a first pressing block that presses against the inner wall of the bend and a second pressing block that presses against the outer wall of the bend, with each second arc-shaped guide surface disposed on the upper end surface of the first pressing block and the second pressing block.

[0009] Furthermore, the aforementioned side support rod is provided with a second adjusting groove arranged parallel to the extension direction of the side support rod. A second side groove is provided on the end face of the second adjusting groove away from the first pressing block. A second adjusting block is provided at the bottom of the second pressing block and slidably disposed in the second adjusting groove. A second side rod is provided on the second adjusting block and slidably connected in the second side groove. A third compression spring is also provided in the second side groove. The two ends of the third compression spring act on the bottom of the second side groove and the second side rod, respectively. The second pressing block presses the bent tube against the first pressing block through the sliding engagement of the second adjusting slider with the second adjusting groove, the sliding engagement of the second side rod with the second side groove, and the continuous force of the third compression spring.

[0010] Furthermore, the two ends of the aforementioned connecting rod are provided with mounting holes for bolts to pass through.

[0011] The present invention has the following positive effects: (1) The present invention uses a positioning device to position each straight pipe and bend pipe synchronously. The two adjacent first and second clamping blocks form a triangular structure, which greatly improves the stability between each straight pipe and bend pipe after installation. It realizes the modular rapid installation and precise positioning of the evaporator pipe as a whole. All straight pipes and bend pipes can be fixed by two positioning devices, which greatly improves the assembly efficiency. The straight pipe is rigidly fixed by the first clamping block, and the bend pipe is flexibly clamped by the positioning component with spring. This ensures the stability of the overall structure and effectively absorbs and buffers the vibration from the compressor and refrigerant pulsation, preventing metal fatigue. The design of the positioning slide rod and the compression spring makes the bend pipe clamping adaptive and elastic, which can adapt to the small deformation and displacement generated by the evaporator pipe during thermal expansion and contraction, avoids stress concentration caused by rigid fixing, improves the reliability of long-term system operation, and effectively solves the problems of low installation efficiency and bend pipe breakage in the long-term vibration working environment in the prior art. It can realize the rapid installation of the evaporator pipe body and buffer the vibration generated by the compressor, which greatly improves the service life of the evaporator pipe body. The structure is ingenious, convenient and practical.

[0012] (2) By setting the first arc-shaped guide surface and the second arc-shaped guide surface, this utility model can play a guiding and positioning role when installing straight pipes and bent pipes, making it easier and smoother for the pipe body to slide into the corresponding slot, further improving the convenience and accuracy of installation and reducing the difficulty of installation.

[0013] (3) Through the cooperation of the first adjusting groove, the slider and the second compression spring, the first locking block itself can slide within a certain range and has a buffer function. Through the setting of the first adjusting groove and the second adjusting groove, the straight pipe is no longer absolutely rigid, allowing the straight pipe to have a slight adaptive adjustment along the axial direction when heated or subjected to force, further releasing thermal stress, and forming a synergy with the flexible fixing at the bend, thus comprehensively improving the evaporator's vibration and impact resistance.

[0014] (4) By specifying the second card block into the first pressing block and the second pressing block respectively attached to the inner and outer walls of the bend, the clamping of the bend is changed from simple single-point or single-sided fixing to a more stable and more balanced circumferential clamping, which effectively prevents the bend from shaking or rotating in the slot and makes the positioning effect more reliable.

[0015] (5) By setting a second side rod and a third compression spring on the second pressure block, this utility model enables it to actively and spring-press the bend, ensuring that the second clamping block can provide a stable and consistent clamping force for bends of different diameters or with manufacturing tolerances, thereby enhancing the versatility of the positioning component and the reliability of clamping.

[0016] (6) By setting mounting holes at both ends of the connecting bottom rod, the entire integrated evaporator module can be quickly and firmly installed into the predetermined position of the ice maker housing by bolts, and the connection between the positioning device and the ice maker is stable and secure.

[0024] The working principle of this utility model is as follows: During use, the operator can install the evaporator tube body with the two connecting base rods 31. During installation, the first locking block 32 adjusts its position through the sliding engagement of the first adjusting slider 323 and the first adjusting groove 312, the sliding engagement of each first side rod 324 and the corresponding first side groove 313, and the continuous force applied by each second compression spring 325.
