Description

Technical Field

[0001] This application relates to the technical field of ice makers, and in particular to an ice maker with an automatic ice dispensing mechanism. Background Technology

[0002] An ice maker is a mechanical device that cools and freezes water into ice through an ice-making system. Ice makers utilize the phase change cycle of the refrigerant to transfer heat, thus completing the ice-making process. The core components of an ice maker include the ice-making system (compressor, condenser, expansion valve, evaporator), water supply system, control system, ice storage device (ice storage tank, ice discharge chute), and ice discharge assembly (rotating blades, ice pusher).

[0003] In related technologies, ice-making systems absorb and release heat by compressing refrigerant. The compressor compresses the low-temperature, low-pressure gaseous refrigerant into a high-temperature, high-pressure gas. After being cooled by the condenser, it becomes a high-pressure liquid refrigerant, which then passes through an expansion valve to reduce its pressure before entering the evaporator. In the evaporator, it absorbs heat from the water, causing it to condense into ice. The high-temperature, high-pressure refrigerant gas discharged from the compressor enters the evaporator jacket, where heat exchange melts the water film between the ice layer and the evaporator, causing the ice blocks to fall into the ice storage tank under gravity or mechanical action. The ice discharging assembly automatically pushes the ice blocks from the ice storage tank to the ice outlet, automating the ice discharging process, reducing manual operation costs, and improving ice-making efficiency.

[0004] Regarding the aforementioned technologies, when the ice maker is in the ice-making state (i.e., the stage in which ice blocks are continuously received and stored in the ice storage tank), the ice blocks naturally accumulate at the bottom of the ice storage tank. The reciprocating motion of the automatic ice dispensing mechanism may cause slight vibration or compression, which may cause some ice blocks to accidentally slide out from the ice dispensing port and fall down, resulting in ice block waste and reducing the actual ice output. Utility Model Content

[0005] In order to improve the problem that some ice blocks may accidentally slip out of the ice outlet in the automatic ice dispensing mechanism and avoid ice waste, this application provides an ice maker with an automatic ice dispensing mechanism.

[0006] The ice maker with an automatic ice dispensing mechanism provided in this application adopts the following technical solution: An ice maker with an automatic ice dispensing mechanism includes an ice-making tank and an ice storage tank arranged adjacent to each other and connected to each other, an ice-making mechanism disposed in the ice-making tank, and an ice dispensing mechanism disposed in the ice storage tank. The ice storage tank has an ice dispensing shell at an adjacent position on one side for cooperating with the ice dispensing mechanism. The ice dispensing shell is connected to the ice storage tank. The ice dispensing shell has an ice outlet on its bottom side for ice blocks to fall into. The ice outlet housing is rotatably connected to an ice baffle plate for blocking the ice outlet, and the ice outlet housing is provided with a first driving component for driving the ice baffle plate to rotate.

[0007] By adopting the above technical solution, the risk of ice blocks accidentally slipping out during ice making is reduced by using an ice baffle to protect the ice outlet. In non-ice-dispensing conditions (i.e., during ice making or after ice dispensing), the first drive unit drives the ice baffle to rotate to the closed position. The ice baffle forms a barrier between the ice dispensing housing and the ice storage tank, preventing naturally accumulated ice blocks in the storage tank from slipping out of the ice outlet due to the reciprocating vibration or compression of the automatic ice dispensing mechanism, thus reducing ice waste. The first drive unit controls the opening and closing angle of the ice baffle. When ice needs to be dispensed, the first drive unit drives the ice baffle to rotate to a set angle. At this time, the ice dispensing housing forms an ice-guiding channel between the ice baffle and the ice storage tank, cooperating with the ice dispensing mechanism to allow the ice blocks to slide smoothly out of the ice outlet, ensuring the continuity and controllability of the ice dispensing process. After ice dispensing is completed, the first drive unit drives the ice baffle to reset and close, again blocking the ice outlet to prevent ice blocks from slipping out during subsequent ice making processes. The operation logic is clear and highly reliable.

[0008] Furthermore, the ice dispensing mechanism includes an ice guide rod for transferring ice blocks to the ice dispensing port position and a second driving component for driving the ice guide rod; The ice guide rod is arranged inclined upwards in the ice storage tank from the side away from the ice outlet to the side closer to the ice outlet, and the ice storage tank has an ice guide slope at the bottom that matches the inclination angle of the ice guide rod.

[0009] By adopting the above technical solution, the upward tilt of the ice guide rod matches the angle of the ice guide slope in the ice storage tank, reducing the resistance to the movement of ice blocks within the tank. Under its own gravity, the ice blocks naturally concentrate at the lower end of the ice guide rod along the ice guide slope. Combined with the traction force generated when the second drive component rotates the ice guide rod, the ice blocks can smoothly slide towards the outlet along the continuous inclined path formed by the ice guide rod and the ice guide slope. This avoids the problem of ice blocks getting stuck in the ice storage tank due to accumulation or friction, significantly improving the continuity and efficiency of the ice discharge process.

[0010] Furthermore, the ice outlet housing includes a lower housing for fixed connection with the ice storage tank and an upper housing installed on the upper part of the lower housing, and the second driving component is installed on the upper housing and drives the ice guide rod to rotate axially.

[0011] By adopting the above technical solution, the prefabricated lower and upper shells enhance the installation flexibility and maintenance convenience of the ice dispensing shell. The lower shell is directly fixed to the ice storage tank, while the upper shell, as an independent component, provides installation space for the second drive component. It also facilitates the disassembly of the ice guide rod and drive component, allowing for direct operation during routine inspections, cleaning, or troubleshooting without the need to empty the ice from the ice storage tank or disassemble the entire ice dispensing mechanism, significantly reducing maintenance and time costs.

[0012] Furthermore, the ice guide rod includes an inclined shaft connected to the second drive component, lifting blades arranged circumferentially outside the shaft, and an installation end plate located at the end of the shaft away from the second drive component and used to cooperate with the inner wall of the ice storage tank. The lifting blades are arranged spirally outside the shaft to lift ice blocks into the ice outlet shell.

[0013] By adopting the above technical solution, the circumferential arrangement of the spiral lifting blades and the inclination angle of the shaft create a spiral conveying effect, realizing the active lifting and directional conveying of ice blocks. When the second drive component drives the shaft to rotate, the spiral blades rotate synchronously with the shaft, and their spiral helix angle matches the angle of the inclined shaft. This allows the ice blocks at the bottom of the ice storage tank to be gradually pushed upwards along the shaft axis until the ice blocks reach the ice outlet shell and slide out from the ice outlet, improving the continuity and efficiency of the ice discharging process.

[0014] Furthermore, the helix angle of the lifting blade is less than or equal to 90°.

[0015] By adopting the above technical solution, this angle range can effectively balance the relationship between the thrust of the blades on the ice and the rotational resistance, thereby improving the conveying efficiency of the ice. When the helix angle is ≤90°, the tilting direction of the blades and the rotation direction of the guide rod work synergistically. During rotation, the tangential motion direction of the blades is consistent with the conveying direction of the ice, which can convert the tangential force generated by the rotation into a thrust along the shaft axis, pushing the ice to move steadily upward along the helical trajectory of the blades. If the helix angle exceeds 90° (i.e., the blades are excessively outward-turned), the tangential force may generate a reverse component, leading to increased sliding friction between the ice and the blades, and even ice jamming or reverse backflow, reducing the conveying efficiency.

[0016] Furthermore, the ice baffle has a waist-shaped hole at the middle position for cooperating with the shaft.

[0017] By adopting the above technical solution, the waist-shaped hole provides movement clearance for the shaft, avoiding mechanical interference between the ice guide rod and the ice baffle when rotating. When the second drive component drives the shaft to rotate to push ice blocks, there is a risk that the rotation trajectory of the shaft may overlap with the closed position of the ice baffle. The waist-shaped hole allows the shaft to have a certain displacement margin and rotation space in its long axis direction, ensuring that the ice guide rod will not collide or get stuck with the ice baffle during rotation, thus ensuring the continuity and smoothness of the ice block delivery driven by the ice guide rod. The waist-shaped hole achieves precise positioning and matching between the shaft and the ice baffle through shape constraints. The long axis direction of the waist-shaped hole is consistent with the inclined arrangement direction of the ice guide rod, and its length matches the displacement requirements of the shaft. This not only limits the excessive offset of the shaft, but also allows the shaft to move within a reasonable range when slight vibrations occur due to ice block compression. This ensures the fitting accuracy of the ice baffle with the ice storage tank when closed, and the coordination angle with the ice guide rod when open, improving the reliability of the ice outlet shielding and the formation of the ice guide channel.

[0018] Furthermore, the ice outlet housing is provided with a micro switch on its outer wall for controlling the start and stop of the ice baffle plate, and a linkage rod that rotates synchronously with the ice baffle plate to trigger the micro switch is provided on the outer wall of the ice outlet housing at a position adjacent to the micro switch.

[0019] By adopting the above technical solution, the synchronous rotation of the linkage rod and the ice baffle ensures the real-time transmission of position signals, achieving precise control of the ice baffle's opening and closing angle. When the first drive component drives the ice baffle to rotate, the linkage rod rotates synchronously with the ice baffle. When the ice baffle rotates to the set angle (such as fully open or fully closed), the linkage rod precisely touches the contact of the micro switch, triggering the switch to act and sending an electrical signal to the control system, thereby controlling the first drive component to stop rotating. This avoids the inaccuracies of traditional manual adjustment or mechanical limiters, ensuring that the ice baffle reaches the preset position every time it opens and closes, guaranteeing the normal opening and closing state of the ice outlet.

[0020] Furthermore, the ice-making mechanism is located inside the ice-making tank, and the ice-making mechanism includes an evaporator, an ice-making box for cooperating with the evaporator, and an ice-scraping plate disposed in the ice-making box for transferring ice blocks into the ice storage tank. The ice-making box is rotatably connected to the ice-making tank. The ice-making tank is provided with a third driving component for flipping the ice-making box. The ice scraper is located at the upper edge of the ice-making box near the ice storage tank.

[0021] By adopting the above technical solution, the rotating connection of the ice-making box and the flipping action of the third drive component realize the demolding and transfer of ice blocks. After the evaporator finishes making ice, the third drive component drives the ice-making box to flip inside the ice-making tank. The ice blocks inside the ice-making box naturally fall off due to gravity and into the ice-making tank. At the same time, the ice scraper moves synchronously with the flipping of the ice-making box, scraping the ice blocks from the ice-making tank into the ice storage tank, avoiding the ice blocks from adhering to the surface of the ice-making box or evaporator, significantly improving the ice removal efficiency and the integrity of ice block collection.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. By incorporating a rotatable ice baffle and a first driving component, the problem of ice blocks accidentally slipping out of the ice outlet during ice-making is effectively solved. When not dispensing ice, the ice baffle closes to block the ice outlet, preventing ice blocks in the ice storage tank from slipping out due to vibration or compression from the automatic ice dispensing mechanism, thus reducing ice waste. When dispensing ice, the ice baffle rotates open to form an ice guiding channel, which, in conjunction with the ice dispensing mechanism, allows the ice blocks to slide out smoothly. The operation logic is clear and highly reliable, improving the stability of the ice dispensing process and the utilization rate of ice blocks. 2. The ice guiding mechanism optimizes the ice lifting path through the coordinated action of inclined ice guide rods and matching ice guiding ramps. As the spiral lifting blades of the ice guide rods rotate with the shaft, they actively lift the ice blocks at the bottom of the ice storage tank to the ice outlet along the inclined shaft. Combined with the natural guidance of the ice guiding ramp, this reduces the resistance to ice movement, avoids accumulation or jamming, and improves the continuity and efficiency of ice dispensing. 3. The ice-making mechanism achieves efficient demolding and transfer of ice blocks by rotating the ice-making box connected to it and flipping the third drive component, combined with the position of the ice-shoveling plate. After ice making is completed, the third drive component drives the ice-making box to flip, and the ice blocks fall off due to gravity. The ice-shoveling plate moves simultaneously to shovel the ice blocks into the ice storage tank, avoiding ice block adhesion and residue, improving ice demolding efficiency and the integrity of ice block collection, and ensuring the stability of subsequent ice dispensing.

[0029] To make the purpose, technical solution, and advantages of this application clearer, the following description is provided in conjunction with the appendix. Figure 1-5 The present application will be further described in detail with reference to the embodiments.

[0030] This application discloses an ice maker with an automatic ice dispensing mechanism. (Refer to...) Figure 1 and Figure 2 An ice maker with an automatic ice dispensing mechanism includes an ice-making tank 1, an ice storage tank 2, an ice dispensing shell 3, an ice-making mechanism 4, and an ice dispensing mechanism 5. The ice-making tank 1 and the ice storage tank 2 are arranged adjacent to each other and are interconnected. The ice dispensing shell 3 is located at an adjacent position on one side of the ice storage tank 2 and is used to cooperate with the ice dispensing mechanism 5.

[0031] The ice-making mechanism 4 includes an evaporator 41, an ice-making box 42, and an ice-scraping plate 43. The ice-making box 42 works in conjunction with the evaporator 41 to make ice blocks, and the ice-scraping plate 43 is used to transfer the ice blocks into the ice storage tank 2. The ice-making box 42 is located inside the ice storage tank 1 and is rotatably connected to the ice storage tank 1. The ice storage tank 1 is provided with a third driving component 44 on the outside for flipping the ice-making box 42. The ice-scraping plate 43 is movably connected to the upper edge of the ice-making box 42 near the side of the ice storage tank 2.

[0032] After the evaporator 41 finishes making ice, the third drive component 44 drives the ice box 42 to rotate inside the ice making tank 1. The ice cubes in the ice box 42 naturally fall off due to gravity and into the ice making tank 1. At the same time, the ice scraper 43 moves synchronously with the rotation of the ice box 42 to scrape the ice cubes from the ice making tank 1 into the ice storage tank 2, preventing the ice cubes from sticking to the surface of the ice box 42 or the evaporator 41, which significantly improves the ice removal efficiency and the integrity of the ice collection.

[0033] Reference Figure 2 and Figure 3The ice-discharging shell 3 includes a lower shell 31 for fixed connection with the ice storage tank 2 and an upper shell 32 fixedly connected to the upper part of the lower shell 31. The lower shell 31 is in communication with the ice storage tank 2, and the lower shell 31 has an ice outlet 311 on its bottom side for ice blocks to fall. The ice-discharging mechanism 5 is located inside the ice storage tank 2 and the ice-discharging shell 3, thereby transferring the ice blocks in the ice storage tank 2 to the ice-discharging shell 3, whereby they fall from the ice outlet 311.

[0034] The ice discharging mechanism 5 includes an ice guide rod 51 and a second driving component 52. The second driving component 52 is mounted on the upper housing 32 and drives the ice guide rod 51 to rotate axially. The ice guide rod 51 is used to transfer ice blocks to the ice outlet 311. The ice guide rod 51 is arranged inclined upwards in the ice storage tank 2 from the side away from the ice outlet 311 to the side closer to the ice outlet 311. The ice storage tank 2 has an ice guiding slope 21 at the bottom that matches the inclination angle of the ice guide rod 51.

[0035] Reference Figure 4 and Figure 5 The ice guide rod 51 includes a shaft 511, a lifting blade 512, and a mounting end plate 513. The shaft 511 is arranged at an angle and connected to the second drive component 52. The lifting blade 512 is arranged circumferentially outside the shaft 511. The mounting end plate 513 is fixedly connected to the end of the shaft 511 away from the second drive component 52, so as to cooperate with the inner wall of the ice storage tank 2.

[0036] The lifting blades 512 are arranged in a spiral shape outside the shaft 511, with a spiral helix angle of less than or equal to 90°. When the second drive component 52 drives the shaft 511 to rotate, the spiral blades rotate synchronously with the shaft 511, and their spiral helix angle matches the angle of the inclined shaft 511, which can gradually push the ice blocks at the bottom of the ice storage tank 2 upward along the axial direction of the shaft 511. When the spiral helix angle is ≤90°, the tilting direction of the blades and the rotation direction of the ice guide rod 51 work together. During rotation, the tangential motion direction of the blades is consistent with the conveying direction of the ice blocks, which can convert the tangential force generated by the rotation into a thrust along the axial direction of the shaft 511, pushing the ice blocks to move steadily upward along the spiral trajectory of the blades; if the spiral helix angle exceeds 90° (i.e., the blades are excessively outward-turned), the tangential force may generate a reverse component force, resulting in increased sliding friction between the ice blocks and the blades, and even ice block jamming or reverse backflow, reducing the conveying efficiency.

[0037] An ice-discharging shell 3 is rotatably connected to an ice baffle 6 inside the upper shell 32. A first driving component 62 for driving the ice baffle 6 to rotate is installed on the outside of the ice-discharging shell 3. In this embodiment, the first driving component 62, the second driving component 52, and the third driving component 44 are all preferably stepper motors. The ice baffle 6 has a waist-shaped hole 61 at its middle position for cooperating with the shaft 511. The waist-shaped hole 61 provides space for the shaft 511 to move, avoiding mechanical interference between the guide rod 51 and the ice baffle 6 when it rotates. When the second driving component 52 drives the shaft 511 to rotate to push ice blocks, the rotation trajectory of the shaft 511 may overlap with the closed position of the ice baffle 6. The waist-shaped hole 61 allows the shaft 511 a certain displacement margin and rotation space in its long axis direction, ensuring that the guide rod 51 will not collide with or get stuck on the ice baffle 6 during rotation, thus ensuring the continuity and smoothness of the ice block delivery driven by the guide rod 51.

[0038] The ice outlet housing 3 has a micro switch 63 on its outer wall for controlling the start and stop of the ice baffle 6. Adjacent to the micro switch 63 on the outer wall of the ice outlet housing 3 is a linkage rod 64 that rotates synchronously with the ice baffle 6. The synchronous rotation of the linkage rod 64 and the ice baffle 6 ensures real-time transmission of position signals, achieving precise control of the opening and closing angle of the ice baffle 6. When the first drive component 62 drives the ice baffle 6 to rotate, the linkage rod 64 rotates synchronously with the ice baffle 6. When the ice baffle 6 rotates to a set angle (such as fully open or fully closed), the linkage rod 64 precisely touches the contact of the micro switch 63, triggering the switch action and sending an electrical signal to the control system, thereby controlling the first drive component 62 to stop rotating. This avoids the inaccuracies of traditional manual adjustment or mechanical limit switches, ensuring that the ice baffle 6 reaches the preset position each time it opens and closes, guaranteeing the normal opening and closing state of the ice outlet 311.

[0039] The implementation principle of an ice maker with an automatic ice dispensing mechanism according to an embodiment of this application is as follows: During the ice-making stage, after the evaporator 41 completes ice making, the third driving component 44 drives the ice-making box 42 to flip. The ice blocks in the ice-making box 42 fall into the ice-making tank 1 due to gravity. At the same time, the ice scraper 43 located on the upper edge of the ice-making box 42 moves synchronously to scrape the ice blocks from the ice-making tank 1 into the ice storage tank 2, completing the initial collection of ice blocks.

[0040] During the ice storage stage, ice blocks naturally accumulate at the bottom of the ice storage tank 2. At this time, the ice baffle 6 inside the ice outlet shell 3 rotates to the closed position under the action of the first driving component 62, blocking the ice outlet 311 on the bottom side of the ice outlet shell 3, preventing ice blocks in the ice storage tank from accidentally slipping off due to vibration or squeezing of the automatic ice outlet mechanism 5, and reducing ice waste.

[0041] During the ice removal stage, when ice needs to be removed, the first drive component 62 drives the ice baffle 6 to rotate and open. The linkage rod 64 rotates synchronously with the ice baffle 6. When the ice baffle 6 reaches a set angle (such as fully open), the linkage rod 64 touches the micro switch 63 to trigger a signal, and the first drive component 62 stops. At this time, an ice guiding channel is formed between the ice baffle 6 and the ice storage tank 2. Simultaneously, the second drive component 52 drives the ice guide rod 51 to rotate. The inclined shaft 511 cooperates with the ice guiding ramp 21 at the bottom of the ice storage tank 2. The spiral lifting blade 512 rotates with the shaft 511, pushing the ice blocks at the bottom of the ice storage tank upward along the shaft 511, and finally sliding out from the ice outlet 311. After ice removal is completed, the first drive component 62 drives the ice baffle 6 to reset and close, blocking the ice outlet 311, preparing for the next round of ice making and storage.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
