[0016] According to one embodiment of the present invention, the water tank is provided with a water supply component, the water supply component is in fluid communication with the water inlet through a water inlet pipe, and the water supply component is in fluid communication with the water tank through a water return pipe.

[0017] According to one embodiment of the present invention, at least one of the water collection box and the water tank is provided with a water heating element and an air supply element, the water heating element is used to heat the water in the water collection box and the water tank, and the air supply element is directed towards the water collection box.

[0018] According to an embodiment of the present invention, the housing is provided with a first heating element and a first temperature detection element corresponding to the first ice-making mold. After the heating time of the first heating element reaches a first preset time or the detection temperature of the first temperature detection element reaches a first preset temperature, the first driving element drives the second ice-making mold to switch from the bonding position to the separation position. And / or, The housing is provided with a second heating element and a second temperature detection element corresponding to the second ice-making mold. After the heating time of the second heating element reaches the second preset time or the detection temperature of the second temperature detection element reaches the second preset temperature, the second driving element drives the second ice-making mold to rotate relative to the first ice-making mold.

[0019] According to one embodiment of the present invention, the first ice mold is provided with a first corrugated surface, and the second ice mold is provided with a second corrugated surface. At the fitting position, the first corrugated surface and the second corrugated surface are engaged with each other to achieve a seal between the first ice mold and the second ice mold.

[0020] A second aspect of the present invention provides a control method for an ice maker as described above, comprising: Once the ice-making time has reached the ice-making duration or the temperature detected by the first temperature sensor has reached the ice-making temperature, the first heating element is turned on. Once the heating time of the first heating element reaches a first preset time or the detection temperature of the first temperature detection element reaches a first preset temperature, the first driving element drives the second ice-making mold to switch from the bonding position to the separation position. Once the heating time of the second heating element reaches the second preset time or the detection temperature of the second temperature detection element reaches the second preset temperature, the second driving element drives the second ice-making mold to rotate relative to the first ice-making mold.

[0021] According to one embodiment of the present invention, it further includes: Once de-icing is complete, the second drive unit causes the second ice-making mold to flip in the opposite direction relative to the first ice-making mold. Once the second ice-making mold has completed its reverse flipping, the first driving component moves the second ice-making mold from the separated position to the fitted position. Once the second ice-making mold is in the fitted position, at least one of the water heating element, the first heating element, and the second heating element is turned on.

[0022] A third aspect of the present invention also provides a refrigeration device, including a refrigeration chamber in which the ice maker described above is disposed.

[0023] According to the ice maker provided in the first aspect of the present invention, the automatic opening and closing of the ice mold assembly and the automatic ejection of ice blocks are realized through the coordinated operation of the drive assembly and the transmission assembly, greatly improving the ice-making efficiency. When the second ice mold is in a fitted position relative to the first ice mold, the second ice mold and the first ice mold can fit together to form an ice-making space; when the second ice mold is in a separated position relative to the first ice mold, the second ice mold moves away from the first ice mold. When the second ice mold switches from a fitted position to a separated position relative to the first ice mold, the first drive member drives the first connecting rod to move, the first connecting rod synchronously drives the second connecting rod to move, and the second connecting rod synchronously drives the first ice pusher to move, so that at least part of the first ice pusher extends into the first ice mold to eject the ice blocks in the first ice mold. At the same time, the second ice pusher abuts against the abutting part on the housing so that the second ice pusher extends into the second ice mold to eject the ice blocks in the second ice mold. With this design, regardless of whether the ice cube is in the first or second ice-making mold, it can be pushed out of the corresponding mold using the corresponding pusher, thus improving the ice-pushing efficiency of the ice maker. Furthermore, the ice maker's overall structure is rationally designed, with tight fit between components, resulting in a compact structure and small footprint. Users only need to start the ice maker to achieve automatic ice making and dispensing, eliminating the need for manual operation or adjustment, making it simple and quick to use. This ice maker is suitable for various occasions requiring ice making, such as homes, restaurants, and bars, and has broad application prospects.

[0024] According to the control method of the ice maker provided in the second aspect of the present invention, the completion of ice making can be accurately determined by detecting the ice making time or the temperature detected by the first temperature detector. Whether the ice in the first ice mold has separated from the first ice mold can be determined by heating the first heating element or detecting the temperature by the first temperature detector. After the ice in the first ice mold has separated from the first ice mold, the ice completely falls into the second ice mold. At this time, the first driving element drives the second ice mold to switch to the separation position relative to the first ice mold. When the second ice mold moves to the separation position, heating by the second heating element ensures that the ice in the second ice mold has separated from the second ice mold. After the ice in the second ice mold has separated from the second ice mold, the second driving element drives the second ice mold to flip relative to the first ice mold to complete the smooth ice removal. By real-time monitoring of temperature and control of heating time, intelligent control of the ice making process is achieved, making the operation of the equipment simpler and more reliable. By accurately controlling the heating time and temperature, unnecessary energy waste is avoided, and the energy utilization efficiency of the equipment is improved.

[0025] According to a third aspect of the present invention, the refrigeration equipment integrates an ice maker into the refrigeration equipment, making full use of the space in the refrigeration room and avoiding the need for additional space required to purchase an ice maker separately. The coordinated operation of the refrigeration equipment and the ice maker ensures an efficient refrigeration and ice-making process, reducing energy consumption and ice-making time. By integrating the ice maker, the refrigeration equipment not only has a refrigeration function but also an ice-making function, meeting diverse user needs. Attached Figure Description

[0041] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0042] like Figures 1 to 12 As shown, a first aspect of the present invention provides an ice maker, comprising: The housing 100 has an abutment portion 102 provided on it; An ice mold assembly is disposed in the housing 100. The ice mold assembly includes a first ice mold 104 and a second ice mold 106. The second ice mold 106 is adapted to switch between a fitting position and a separating position relative to the first ice mold 104. A first ice pusher 108 is disposed on the first ice mold 104, and a second ice pusher 110 is disposed on the second ice mold 106. The drive assembly is mounted on the housing 100; The transmission assembly includes a first link 112 and a second link 114 that are connected by transmission. The first link 112 is connected to the drive assembly and the second ice mold 106, and the second link 114 is connected to the first ice pusher 108. From the contact position to the separation position, the first link 112 is adapted to drive the second link 114 to move, so that the second link 114 drives at least a portion of the first ice pusher 108 to extend into the first ice mold 104. The second ice pusher 110 is adapted to abut against the abutment portion 102 so that at least a portion of the second ice pusher 110 extends into the second ice mold 106.

[0043] According to the first aspect of the present invention, the ice maker achieves automatic opening and closing of the ice mold assembly and automatic ejection of ice blocks through the coordinated operation of the drive assembly and the transmission assembly, greatly improving ice-making efficiency. When the second ice mold 106 is in a mating position relative to the first ice mold 104, the second ice mold 106 and the first ice mold 104 can fit together to form an ice-making space; when the second ice mold 106 is in a separated position relative to the first ice mold 104, the second ice mold 106 moves away from the first ice mold 104. When the second ice mold 106 switches from a mating position to a separated position relative to the first ice mold 104, the first drive member 116 drives the first connecting rod 112 to move. The first connecting rod 112 simultaneously drives the second connecting rod 114 to move, and the second connecting rod 114 simultaneously drives the first ice pusher 108 to move, so that at least part of the first ice pusher 108 extends into the first ice mold 104 to push out the ice blocks in the first ice mold 104. At the same time, the second ice pusher 110 abuts against the abutting part 102 on the housing 100 so that the second ice pusher 110 extends into the second ice mold 106 to push out the ice blocks in the second ice mold 106. With this setting, regardless of whether the ice blocks are in the first ice mold 104 or the second ice mold 106, the corresponding ice pusher can push out the ice blocks in the corresponding ice mold, thereby improving the ice pushing efficiency of the ice maker. In addition, the overall structure of the ice maker is reasonably designed, and the components are closely matched, making the entire device compact and occupying a small area. Users simply need to start the ice maker to achieve automatic ice making and dispensing, without the need for manual operation or adjustment, making it simple and quick to use. This ice maker is suitable for various occasions requiring ice making, such as homes, restaurants, and bars, and has broad application prospects.

[0044] Please continue reading Figures 1 to 12 The ice maker provided in the first aspect of the present invention mainly includes a housing 100, an ice mold assembly, a drive assembly, and a transmission assembly.

[0045] The housing 100 serves as the main structure of the ice maker, providing an installation platform for other components. The housing 100 is equipped with an abutment part 102, which plays a crucial role in the subsequent ice-pushing process.

[0046] An ice mold assembly is disposed within the housing 100 and is used to manufacture ice cubes. The ice mold assembly includes a first ice mold 104 and a second ice mold 106, wherein the second ice mold 106 can switch between a mating position and a separated position relative to the first ice mold 104. When the second ice mold 106 is in the mating position, the two are in close contact for making ice cubes; when the second ice mold 106 is in the separated position, the two are separated for easy removal of the ice cubes. A first ice pusher 108 is provided on the first ice mold 104, and a second ice pusher 110 is provided on the second ice mold 106. The first ice pusher 108 is used to push the ice cubes out of the first ice mold 104 after they are made, and the second ice pusher 110 is used to push the ice cubes out of the second ice mold 106 after they are made.

[0047] The drive assembly is installed inside the housing 100 and provides power for the entire ice-making and ice-pushing process.

[0048] The transmission assembly includes a first link 112 and a second link 114, which are connected by transmission. The first link 112 is connected to the drive assembly and the second ice mold 106, and the second link 114 is connected to the first ice pusher 108. When the second ice mold 106 moves from the mating position to the separating position, the first link 112 drives the second link 114 to move. The second link 114 can drive at least a portion of the first ice pusher 108 to extend into the first ice mold 104, pushing the ice out of the first ice mold 104. At the same time, the second ice pusher 110 abuts against the abutment portion 102 of the housing 100, causing at least a portion of the second ice pusher 110 to extend into the second ice mold 106, pushing the ice out of the second ice mold 106.

[0049] With this configuration, when the second ice mold 106 switches from the contact position to the separation position, the first ice pusher 108 can push out the ice block in the first ice mold 104, and the second ice pusher 110 can push out the ice block in the second ice mold 106. Thus, after ice making is completed, regardless of whether the ice block remains in the first ice mold 104 or the second ice mold 106, efficient ice removal can be achieved.

[0050] According to one embodiment of the present invention, the driving assembly includes a first driving member 116 and a second driving member 118. The first driving member 116 is convexly connected to a first connecting rod 112. The first driving member 116 is used to drive the second ice mold 106 to switch between a mating position and a separating position. In the separating position, the second driving member 118 is adapted to be convexly connected to the second ice mold 106 to cause the second ice mold 106 to flip relative to the first ice mold 104.

[0051] See Figure 10 In one embodiment of the present invention, the driving component mainly consists of two core parts, namely the first driving element 116 and the second driving element 118.

[0052] The main function of the first driving component 116 is to drive the first connecting rod 112 to move, so that the first connecting rod 112 drives the second ice mold 106 to switch between the fitting position and the separation position.

[0053] When the second ice mold 106 is in the separated position, the second drive member 118 starts to function. The second drive member 118 is responsible for driving the second ice mold 106 to rotate relative to the first ice mold 104 to pour out the ice cubes in the second ice mold 106.

[0054] By controlling the first drive component 116 and the second drive component 118 respectively, the position switching of the second ice-making mold 106 between the contact position and the separation position can be precisely controlled. Simultaneously, the flipping motion of the second ice-making mold 106 can also be controlled, thereby achieving flexible control over the motion state of the entire device. When it is necessary to maintain the relative positional stability between the second ice-making mold 106 and the first ice-making mold 104, the contact position of the second ice-making mold 106 provides reliable constraint; while when a flipping motion is required, the second ice-making mold 106 is allowed to flip relative to the first ice-making mold 104 to achieve ice removal. Through the integrated drive component design, the flipping motion, which originally might have required multiple independent steps or complex mechanisms, can be simplified to the coordinated work of two drive components, thereby reducing operational difficulty and complexity. This design, by optimizing the transmission connection and drive method, improves motion efficiency and accuracy while reducing energy loss and wear, contributing to the overall performance and service life of the entire device.

[0055] According to one embodiment of the present invention, a trigger head 120 is provided on the first connecting rod 112, and a first trigger 122 and a second trigger 124 are provided on the first driving member 116. In the contact position, the trigger head 120 is adapted to trigger the first trigger 122, and in the separation position, the trigger head 120 is adapted to trigger the second trigger 124. The first driving member 116 is adapted to stop based on the triggering state of the trigger head 120 and the first trigger 122 and the second trigger 124.

[0056] See Figure 10 and Figure 11 In one embodiment of the present invention, a trigger head 120 is provided on the first link 112. The trigger head 120 is designed to interact with a specific trigger element, thereby changing the working state of the drive element.

[0057] When the second ice-making mold 106 is in the mating position, the trigger head 120 contacts the first trigger member 122, thereby triggering the first trigger member 122. Similarly, when the second ice-making mold 106 is in the separated position, the trigger head 120 contacts the second trigger member 124, thereby triggering the second trigger member 124.

[0058] Understandably, this triggering mechanism relies on the interaction between the trigger head 120 and the first trigger 122 and the second trigger 124. When the trigger head 120 triggers any of the triggers, it sends a signal to the first drive member 116, instructing it to stop working. This design ensures that the first drive member 116 can accurately stop moving when the second ice mold 106 reaches a predetermined position (whether it is in contact or out). That is, when the second ice mold 106 moves to the out position, the trigger head 120 triggers the second trigger 124, at which point the first drive member 116 stops, and simultaneously, the second drive member 118 actuates to drive the second ice mold 106 to flip relative to the first ice mold 104. When the second ice mold 106 moves in the opposite direction to the contact position, the trigger head 120 triggers the first trigger 122, at which point the first drive member 116 stops in the opposite direction, thereby achieving the closing of the first ice mold 104 and the second ice mold 106.

[0059] By introducing the interaction between the trigger head 120 and the trigger element, the working state of the first drive element 116 can be precisely controlled. Whether in the engagement or disengagement position, the first drive element 116 is ensured to stop at the correct moment, thereby improving the motion accuracy of the entire system. The trigger mechanism design reduces motion errors caused by misoperation or external interference. Once the trigger head 120 contacts the first trigger element 122 or the second trigger element 124, the first drive element 116 immediately stops working, avoiding unnecessary movement or damage. Achieving precise position control through physical triggering instead of complex electronic control logic simplifies system design and maintenance. This reduces system complexity and cost while improving its reliability and durability.

[0060] According to one embodiment of the present invention, a connecting shaft 126 is provided on the second ice mold 106, and a rocker arm 128 is connected to the first connecting rod 112. A connecting groove 130 is provided on the rocker arm 128, and the connecting shaft 126 passes through the connecting groove 130. In the separated position, the second driving member 118 is adapted to be connected to the connecting shaft 126 to drive the second ice mold 106 to flip relative to the first ice mold 104.

[0061] See Figures 9 to 12 In one embodiment of the present invention, a connecting shaft 126 is provided on the second ice mold 106, which is intended to achieve the flipping operation of the second ice mold 106 relative to the first ice mold 104 through the cooperation of the connecting shaft 126 and the second driving member 118, so that the ice cubes can be easily separated from the second ice mold 106 after the ice is made.

[0062] Specifically, a connecting shaft 126 is provided on the second ice-making mold 106, serving as a fulcrum for the flipping action. Simultaneously, a rocker arm 128 is connected to the first connecting rod 112, and the rocker arm 128 has a connecting groove 130, through which the connecting shaft 126 can pass. With this arrangement, when the first connecting rod 112 moves, the sidewall of the connecting groove 130 abuts against the connecting shaft 126, thereby driving the connecting shaft 126 to move through the movement of the first connecting rod 112, thus switching the second ice-making mold 106 between a mating position and a separating position.

[0063] When the ice maker is working, when it is necessary to flip the second ice mold 106 to separate the ice, the second driving component 118 (such as a motor, cylinder, or other power device) will be connected to the connecting shaft 126 for transmission. Through the driving action of the second driving component 118, the connecting shaft 126 will drive the second ice mold 106 to flip relative to the first ice mold 104.

[0064] By flipping the second ice mold 106, ice cubes can be separated from the mold more easily, thus improving the overall efficiency of the ice maker. The automatic control of the flipping action is achieved through the transmission connection between the second drive component 118 and the connecting shaft 126, reducing the tediousness and errors of manual operation. The automated flipping operation and convenient ice cube separation method make it easier for users to operate the ice maker, enhancing the overall user experience. By placing the connecting shaft 126 on the second ice mold 106 and connecting it to the first connecting rod 112 via the rocker arm 128 and connecting groove 130, the entire ice maker has a more compact structure and better stability.

[0065] According to one embodiment of the present invention, a connector 132 is sleeved on the connecting shaft 126, a hanging part 134 is provided on the rocker arm 128, and a tension spring 136 is provided between the connector 132 and the hanging part 134. From the separated position to the fitted position, the tension spring 136 is adapted to tighten the second ice mold 106 so that the second ice mold 106 and the first ice mold 104 fit together.

[0066] See Figures 9 to 12 In one embodiment of the present invention, a connector 132 is fitted onto the connecting shaft 126. The connector 132 makes the connection between the tension spring 136 and the connecting shaft 126 more flexible and stable. The connector 132 can adopt a shape and size that matches the connecting shaft 126 to ensure a tight fit between the two. At the same time, the connector 132 can also be designed with different materials and structures according to actual needs to meet the special requirements of the connection method of the tension spring 136.

[0067] The rocker arm 128 is provided with a hanging part 134, which is located above the connecting groove 130 and is used to connect one end of the tension spring 136, while the other end of the tension spring 136 is connected to the connector 132.

[0068] The connector 132 makes the connection between the tension spring 136 and the connecting shaft 126 more secure, reducing malfunctions and damage caused by loose connections. Since the connector 132 can withstand some of the force and torque from the connecting shaft 126, it reduces the burden on the tension spring 136, extending its service life. The design of the connector 132 makes the installation and replacement of the tension spring 136 easier, eliminating the need to disassemble the entire connecting shaft 126, thus reducing maintenance costs and time. By optimizing the connection between the connecting shaft 126 and the tension spring 136, the overall performance of the ice maker is improved, including ice-making efficiency, stability, and durability.

[0069] When the second ice mold 106 is in the fitted position, to improve the sealing between the second ice mold 106 and the first ice mold 104, the tension spring 136 is in a stretched state. Thus, the tension spring 136 provides a certain elastic tension to the second ice mold 106, ensuring the fit between the second ice mold 106 and the first ice mold 104. When it is necessary to open the second ice mold 106, the first drive component 116 is activated, driving the rocker arm 128 to rotate. During the movement, the distance between the hanging part 134 on the rocker arm 128 and the connecting shaft 126 gradually decreases, and the tension spring 136 gradually returns from the stretched state to its initial state. As the rocker arm 128 continues to move, the connecting shaft 126 abuts against the side wall of the connecting groove 130 on the other side. At this time, the continuous rotation of the rocker arm 128 can drive the second ice mold 106 to the separated position.

[0070] According to one embodiment of the present invention, a guide groove 138 is provided on the second connecting rod 114 along its length direction. The connecting shaft 126 passes through the guide groove 138 and the connecting groove 130 in sequence. From the contact position to the separation position, the connecting shaft 126 is adapted to abut against the first groove sidewall of the guide groove 138 so that the second connecting rod 114 drives at least part of the first ice pusher 108 to extend into the first ice mold 104. From the separation position to the contact position, the connecting shaft 126 is adapted to abut against the second groove sidewall of the guide groove 138 so that the second connecting rod 114 drives the first ice pusher 108 to exit the first ice mold 104. The first groove sidewall and the second groove sidewall are arranged opposite to each other.

[0071] See Figure 9 , Figure 10 and Figure 12In one embodiment of the invention, a guide groove 138 is formed on the second connecting rod 114 to guide the movement of the connecting shaft 126. The shape and size of the guide groove 138 are designed to cooperate with the connecting shaft 126 and allow the connecting shaft 126 to slide or rotate within a certain range. Thus, when the second ice mold 106 moves, the connecting shaft 126 moves along the guide groove 138, thereby driving the second connecting rod 114 to perform corresponding actions.

[0072] Understandably, when the first link 112 is activated, it drives the rocker arm 128 to rotate. The side wall of the connecting groove 130 on the rocker arm 128 abuts against the connecting shaft 126. When the connecting shaft 126 is activated, it can move along the guide groove 138 on the second link 114. When the connecting shaft 126 abuts against the side wall of the guide groove 138, it can drive the second link 114 to move downward. At the same time, the second link 114 can drive the first ice pusher 108 to extend into the first ice mold 104. Similarly, when the first link 112 moves in the opposite direction, the side wall of the connecting groove 130 on the rocker arm 128 abuts against the connecting shaft 126. When the connecting shaft 126 moves, it can move in the opposite direction along the guide groove 138 on the second link 114. When the connecting shaft 126 abuts against the side wall of the guide groove 138 on the other side, it can drive the second link 114 to move upward. At the same time, the second link 114 can drive the first ice pusher 108 to exit from the first ice mold 104.

[0073] According to one embodiment of the present invention, a pressure rod 140 is provided at a position corresponding to the side wall of the second groove in the guide groove 138, and an elastic buffer member 142 is provided between the pressure rod 140 and the side wall of the second groove.

[0074] See Figure 12 In one embodiment of the present invention, the design of the guide groove 138 is further optimized. Specifically, a pressure rod 140 is added at the position corresponding to the second groove sidewall of the guide groove 138, and an elastic buffer 142 is provided between the pressure rod 140 and the second groove sidewall. This design aims to improve the stability and durability of the ice maker during operation.

[0075] A pressure rod 140 passes through the second groove sidewall of the guide groove 138 and is used to contact the connecting shaft 126 at a specific stage. The shape and size of the pressure rod 140 are designed to mate with the connecting shaft 126, and the connecting shaft 126 contacts the pressure rod 140 when it moves along the guide groove 138 to a position corresponding to the second groove sidewall.

[0076] An elastic buffer 142 is disposed between the pressure rod 140 and the side wall of the second groove to provide a cushioning effect. The elastic buffer 142 may be made of rubber, spring, or other elastic materials. When the connecting shaft 126 contacts the pressure rod 140, the elastic buffer 142 can absorb part of the impact force, thereby protecting the various components of the ice maker from damage.

[0077] By adding a pressure rod 140 and an elastic buffer 142, the impact of the connecting shaft 126 on the guide groove 138 and the second connecting rod 114 during movement can be reduced, thereby improving the stability of the ice maker during operation. The elastic buffer 142 can also absorb some of the impact force, thereby extending the service life of various components of the ice maker and enhancing the durability of the equipment. The design of the pressure rod 140 and the elastic buffer 142 makes the connecting shaft 126 move more smoothly during movement, avoiding excessive vibration or shaking, thus optimizing the movement trajectory of the connecting shaft 126. Because the ice maker is more stable and durable during operation, users can enjoy a smoother and more reliable ice-making experience.

[0078] More importantly, when the connecting shaft 126 contacts the pressure rod 140, if the first ice pusher 108 cannot push the ice in the first ice mold 104, the elastic buffer 142 will gradually store energy as the driving component continues to operate, thereby increasing the pressure applied to the first ice pusher 108. When the ice in the first ice mold 104 gradually separates from the first ice mold 104, the first ice pusher 108 will apply greater pressure to the ice in the first ice mold 104 so that the ice in the first ice mold 104 is pushed out quickly.

[0079] According to one embodiment of the present invention, an elastic reset member 144 is provided between the second ice mold 106 and the second ice pusher 110. From the separation position to the contact position, the elastic reset member 144 is adapted to drive the second ice pusher 110 out of the second ice mold 106.

[0080] See Figure 6 In one embodiment of the present invention, an abutment is added to one end of the second ice pusher 110 away from the second ice mold 106, and an elastic reset member 144 is sleeved on the second ice pusher 110, with the two ends of the elastic reset member 144 abutting against the second ice mold 106 and the abutment respectively.

[0081] The abutment is a protruding part located at the end of the second ice pusher 110 opposite to the second ice mold 106. The abutment can be of any shape and size, as long as it can ensure effective contact with the abutment portion 102 of the housing 100 and push the second ice pusher 110 to move. The presence of the abutment allows the second ice pusher 110 to interact more stably with the abutment portion 102 of the housing 100 when pushing out ice, thereby improving the pushing effect.

[0082] An elastic reset element 144 (such as a spring) is sleeved on the second ice pusher 110, with its two ends abutting against the second ice mold 106 and the abutment, respectively. This design allows the second ice pusher 110 to buffer and reset to a certain extent when subjected to external force. When the second ice mold 106 switches from the contact position to the separation position, the abutment interacts with the contact portion 102 of the housing 100, pushing the second ice pusher 110 to move, while the elastic reset element 144 is compressed; when the second ice mold 106 returns from the separation position to the contact position, the elastic reset element 144 releases its stored energy, pushing the second ice pusher 110 to reset.

[0083] The abutment joint allows the second ice pusher 110 to interact more stably with the abutment portion 102 of the housing 100 when pushing out ice, thereby improving the ice pushing effect and helping to reduce ice breakage and residue during the pushing process. The introduction of the elastic reset member 144 allows the second ice pusher 110 to buffer and reset after being subjected to external force, helping to protect the second ice pusher 110 and the second ice mold 106 from excessive impact, while ensuring that the second ice pusher 110 accurately resets during each ice-making process. Since the elastic reset member 144 can absorb some of the impact force, it helps to reduce wear on the second ice pusher 110 and the second ice mold 106, thereby extending the service life of the ice maker. Because the elastic reset member 144 can automatically push the second ice pusher 110 back to its original position, the user can achieve the reset action of the second ice pusher 110 without manual operation. This simplifies the operation process and improves the user experience.

[0084] According to one embodiment of the present invention, a water collection box 146 and a water tank 148 are provided on the housing 100. The water collection box 146 is in fluid communication with the first ice mold 104, the second ice mold 106 and the water tank 148 respectively. The first ice mold 104 is provided with a water inlet 150 and a water outlet 152. The water tank 148 is in fluid communication with the water inlet 150 and the water collection box 146 is in fluid communication with the water outlet 152. The water outlet 152 is located at the top of the first ice mold 104. The cross-sectional area of ​​the water outlet 152 gradually decreases from the first ice mold 104 to the water collection box 146, and the water inlet 150 and the water outlet 152 are staggered.

[0085] See Figure 9 In one embodiment of the present invention, the water collection box 146 is connected above the first ice mold 104 and is in fluid communication with the first ice mold 104, the second ice mold 106 and the water tank 148 respectively.

[0086] The water collection box 146, serving as an intermediate component for storing and transferring water, is positioned above the first ice mold 104 to facilitate the receipt of water flowing from the outlet 152. The design of the water collection box 146 takes into account the collection and flow of water, ensuring that water can smoothly enter and be stored, while also facilitating subsequent processing or return.

[0087] The water collection box 146 is connected to the water outlet 152 at the top of the first ice mold 104, ensuring that after ice making is completed, the residual water or water that needs to be discharged can flow directly into the water collection box 146.

[0088] The water collection box 146 can also be connected to the water tank 148 via a water inlet, so that the water collected in the water collection box 146 can be returned to the water tank 148 as needed, realizing the recycling of water resources. At the same time, this design also facilitates the cleaning or emptying of the water collection box 146.

[0089] The design of the water collection box 146 allows water flowing from the outlet 152 to be effectively collected and returned to the water tank 148, reducing water waste and improving water utilization. By collecting and draining residual water in a timely manner, the water collection box 146 helps maintain the cleanliness of the first ice mold 104 and the entire ice-making space, preventing bacterial growth or odor caused by residual moisture. As an independent component, the water collection box 146 is easy for users to clean, empty, or replace, simplifying the daily maintenance of the ice maker.

[0090] The structure of the water outlet 152 is specially designed so that its cross-sectional area gradually decreases from the first ice mold 104 toward the water collection box 146. This design is based on the principles of fluid mechanics and aims to optimize the water discharge process and improve the overall performance of the ice maker.

[0091] Specifically, the outlet 152 has a relatively large opening at the first ice-making mold 104. This design ensures that after ice making is complete, residual water can quickly and smoothly flow into the outlet 152. As the water flows towards the water collection box 146, the cross-sectional area of ​​the outlet 152 gradually decreases. This design creates a natural guiding and accelerating effect. When water flows through the outlet 152, its flow velocity gradually increases due to the decrease in cross-sectional area, which helps to expel water from the ice-making space more quickly and send it into the water collection box 146.

[0092] The gradually decreasing cross-sectional area of ​​the outlet 152 significantly improves drainage efficiency. After ice making, residual water can be quickly and smoothly discharged through the outlet 152, reducing drainage time and improving the overall efficiency of the ice maker. Due to the improved drainage efficiency, the amount of residual moisture in the ice-making space is greatly reduced. This helps maintain the cleanliness and dryness of the ice-making space, preventing bacterial growth and odors caused by residual moisture. The design of the outlet 152 not only considers drainage efficiency but also optimizes the water flow path. The gradually decreasing cross-sectional area allows the water flow to form a natural guiding effect as it passes through the outlet 152, reducing water flow turbulence and energy loss.

[0093] In the vertical direction, the inlet 150 is designed to be offset from the outlet 152. This arrangement ensures effective circulation and uniform distribution of water within the ice-making space. The inlet 150 is typically located at a lower position so that water can fill the entire ice-making space from bottom to top, while the higher position of the outlet 152 facilitates water discharge.

[0094] By optimizing the water flow path and ensuring the uniform distribution of water within the ice-making space, the high-positioning of the outlet 152 and the staggered layout of the inlet 150 and outlet 152 work together to reduce the residual moisture after ice making, which helps to keep the ice mold dry and clean.

[0095] According to one embodiment of the present invention, a water supply component 154 is provided on the water tank 148. The water supply component 154 is in fluid communication with the water inlet 150 through the water inlet pipe 156, and the water supply component 154 is in fluid communication with the water tank 148 through the water return pipe 158.

[0096] See Figure 7 In one embodiment of the present invention, the water supply component 154 is connected to the water inlet 150 via the water inlet pipe 156, and is used to pump water from the water tank 148 and inject it into the ice-making space, providing the necessary water source for the ice-making process. Simultaneously, the water supply component 154 is also connected to the water tank 148 via the return water pipe 158, so that water in the ice-making space or system can be returned to the water tank 148 when needed (such as for drainage, cleaning, or water recycling), achieving effective recycling and utilization of water resources. More importantly, if the water inlet pipe 156 freezes, the water pumped out by the water supply component 154 can flow back into the water tank 148 through the return water pipe 158, avoiding pressure buildup or overload in the water supply component 154.

[0097] According to one embodiment of the present invention, at least one of the water collection box 146 and the water tank 148 is provided with a water heating element 160 and an air supply element 162. The water heating element 160 is used to heat the water in the water collection box 146 and the water tank 148, and the air supply element 162 is directed towards the water collection box 146.

[0098] See Figure 8 In one embodiment of the present invention, a water heating element 160 is disposed within the housing 100, and its function is to heat the water flowing into the water supply tank 148 from the water collection box 146. The water heating element 160 is designed to increase the temperature of the water so as to preheat the water when necessary (such as when the water temperature is too low and affects the ice-making efficiency), thereby optimizing the ice-making process. This can prevent the water from freezing and effectively prevent the ice maker from burning dry.

[0099] The air supply component 162 can be a fan blade or a blower, and is installed in a suitable position on the housing 100 to ensure that its airflow can be directly directed towards the water collection box 146. This design can use the airflow generated by the air supply component 162 to accelerate the airflow circulation, so that the heat generated by the water heating component 160 can be evenly distributed on the surface of the water collection box 146, thereby achieving uniform heating of the water in the water collection box 146.

[0100] In other embodiments, the air supply component 162 can also serve to dry the water collection box 146, especially when there is a large amount of water accumulated in the water collection box 146 or when rapid drying is required. By accelerating the evaporation of moisture, the air supply component 162 helps to reduce the amount of water accumulated in the water collection box 146, thereby keeping the water collection box 146 clean and dry.

[0101] The airflow generated by the air supply component 162 enables the circulation and distribution of heat generated by the water heating component 160, ensuring that the water in the water collection box 146 is heated evenly, which is beneficial for achieving uniform temperature rise of the water in the water collection box 146. When the water in the water collection box 146 flows back to the water tank 148, freezing of the water in the water collection box 146 and the water tank 148 can be prevented. By uniformly raising the temperature of the water in the water collection box 146 and the water tank 148, dry burning and other problems can be avoided in the ice maker.

[0102] According to one embodiment of the present invention, the housing 100 is provided with a first heating element (not shown in the figure) and a first temperature detection element (not shown in the figure) corresponding to the first ice mold 104. After the heating time of the first heating element reaches a first preset time or the detection temperature of the first temperature detection element reaches a first preset temperature, the first driving member 116 drives the second ice mold 106 to switch from the contact position to the separation position; and / or, the housing 100 is provided with a second heating element (not shown in the figure) and a second temperature detection element (not shown in the figure) corresponding to the second ice mold 106. After the heating time of the second heating element reaches a second preset time or the detection temperature of the second temperature detection element reaches a second preset temperature, the second driving member 118 drives the second ice mold 106 to flip relative to the first ice mold 104.

[0103] In one embodiment of the present invention, the housing 100 is provided with a first heating element and a first temperature detection element corresponding to the first ice mold 104. The first heating element is used to heat the first ice mold 104 to accelerate the separation of ice from the first ice mold 104. The first temperature detection element is used to monitor the temperature of the first ice mold 104 in real time.

[0104] When the heating time of the first heating element reaches the first preset time, or the temperature detected by the first temperature detection element reaches the first preset temperature, it indicates that the ice in the first ice-making mold 104 has loosened sufficiently. At this time, the first driving element 116 will drive the second ice-making mold 106 to switch from the fitting position to the separation position to prepare for the ice to fall off.

[0105] The housing 100 is also provided with a second heating element and a second temperature detection element corresponding to the second ice mold 106. The second heating element is used to heat the second ice mold 106, also to accelerate the separation of the ice cube from the second ice mold 106. The second temperature detection element is used to monitor the temperature of the second ice mold 106 in real time.

[0106] When the heating time of the second heating element reaches the second preset time, or the temperature detected by the second temperature detection element reaches the second preset temperature, it indicates that the ice in the second ice-making mold 106 has been sufficiently loosened. At this time, the second driving element 118 will drive the second ice-making mold 106 to rotate relative to the first ice-making mold 104, thereby realizing the automatic release of the ice.

[0107] By installing heating elements and temperature detection elements on the housing 100 and the corresponding ice-making mold, the temperature of the ice-making mold can be precisely controlled, thereby accelerating the ice-forming and release process and improving ice-making efficiency. The application of heating elements weakens the adhesion between the ice and the ice-making mold, making it easier for the ice to release automatically, reducing the need for manual intervention and increasing the success rate of demolding. Through real-time monitoring by the temperature detection elements and the judgment of preset conditions, intelligent control of the ice-making process can be achieved, making the operation of the equipment simpler and more reliable.

[0108] According to one embodiment of the present invention, a first corrugated surface 164 is provided on a first ice mold 104, and a second corrugated surface 166 is provided on a second ice mold 106. At the fitting position, the first corrugated surface 164 and the second corrugated surface 166 are engaged with each other to achieve a seal between the first ice mold 104 and the second ice mold 106.

[0109] See Figure 5In one embodiment of the present invention, the surface of the mating surface of the first ice mold 104 has a first corrugated surface 164. The design of the first corrugated surface 164 not only increases the surface area of ​​the ice mold, which is conducive to freezing water more quickly, but also provides a unique texture and shape for the final ice cubes, increasing the aesthetics and practicality of the ice cubes.

[0110] The second ice-making mold 106 corresponds to the first ice-making mold 104, and the surface of the mating surface of the second ice-making mold 106 is provided with a second corrugated surface 166. The first corrugated surface 164 and the second corrugated surface 166 are structurally and functionally matched, and when the first ice-making mold 104 and the second ice-making mold 106 are in the mating position, they can be tightly joined together to form a complete ice-making cavity. This design ensures that moisture is effectively confined between the corrugated surfaces during the freezing process, thereby producing ice blocks with regular shapes and uniform quality.

[0111] See Figure 13 A second aspect of the present invention provides a control method for an ice maker as described above, comprising: Step 10: Once the ice-making time has reached the ice-making duration or the detection temperature of the first temperature sensor has reached the ice-making temperature, the first heating element is turned on. Step 20: Determine that the heating time of the first heating element reaches the first preset time or the detection temperature of the first temperature detection element reaches the first preset temperature, and the first driving element 116 drives the second ice-making mold 106 to switch from the bonding position to the separation position. Step 30: After determining that the heating time of the second heating element reaches the second preset time or the detection temperature of the second temperature detection element reaches the second preset temperature, the second driving element 118 drives the second ice-making mold 106 to rotate relative to the first ice-making mold 104.

[0112] According to the control method of the ice maker provided in the second aspect embodiment of the present invention, the completion of ice making can be accurately determined by detecting the ice making time or the temperature detected by the first temperature detector. Whether the ice in the first ice mold 104 has separated from the first ice mold 104 can be determined by heating the first heating element or detecting the temperature by the first temperature detector. After the ice in the first ice mold 104 has separated from the first ice mold 104, the ice completely falls into the second ice mold 106. At this time, the first driving element 116 drives the second ice mold 106 to switch to the separation position relative to the first ice mold 104. After the second ice mold 106 moves to the separation position, heating by the second heating element ensures that the ice in the second ice mold 106 has separated from the second ice mold 106. After the ice in the second ice mold 106 has separated from the second ice mold, the second driving element 118 drives the second ice mold 106 to flip relative to the first ice mold 104 to successfully remove the ice. By monitoring temperature in real time and controlling heating time, intelligent control of the ice-making process is achieved, making the equipment easier and more reliable to operate. Precise control of heating time and temperature avoids unnecessary energy waste and improves the equipment's energy efficiency.

[0113] Please continue reading Figure 13 A second aspect of the present invention provides a control method for an ice maker, which aims to achieve an efficient ice-making process and smooth ice detachment by precisely controlling the operation of heating and driving components.

[0114] Step 10: Once the ice-making time has reached the ice-making duration or the temperature detected by the first temperature sensor has reached the ice-making temperature, the first heating element is activated; After the ice maker starts working, it first determines whether the ice-making conditions have been met based on the preset ice-making time or the temperature monitored in real time by the first temperature detection element.

[0115] When the ice-making time reaches the preset ice-making duration, or when the temperature detected by the first temperature sensor reaches the preset ice-making temperature, it is considered that the ice block has basically formed, and the first heating element is turned on.

[0116] The first heating element heats the first ice mold 104 in preparation for the ice to be released.

[0117] Step 20: Determine that the heating time of the first heating element reaches the first preset time or the detection temperature of the first temperature detection element reaches the first preset temperature, and the first driving element 116 drives the second ice-making mold 106 to switch from the bonding position to the separation position. After the first heating element is turned on, continue to monitor its heating duration or the detection temperature of the first temperature detection element.

[0118] When the heating time of the first heating element reaches the preset first preset time, or the temperature detected by the first temperature detection element reaches the preset first preset temperature, it is considered that the ice block has been loosened enough and the ice block has completely fallen into the second ice-making mold 106, and the drive component starts to work.

[0119] The first driving component 116 drives the second ice-making mold 106 to switch from the contact position (i.e., the position that is in close contact with the first ice-making mold 104) to the separation position, in preparation for the ice to fall off.

[0120] Step 30: After determining that the heating time of the second heating element reaches the second preset time or the detection temperature of the second temperature detection element reaches the second preset temperature, the second driving element 118 drives the second ice-making mold 106 to rotate relative to the first ice-making mold 104. After the second ice mold 106 is separated from the first ice mold 104, the second heating element is turned on to heat the second ice mold 106.

[0121] Monitor the heating time of the second heating element or the detection temperature of the second temperature detection element.

[0122] When the heating time of the second heating element reaches the preset second preset time, or the temperature detected by the second temperature detection element reaches the preset second preset temperature, it is considered that the ice block has been sufficiently loosened and can be removed from the second ice-making mold 106.

[0123] At this time, the second driving component 118 starts to work, driving the second ice mold 106 to rotate relative to the first ice mold 104, so that the ice cubes can be automatically released.

[0124] The control method for an ice maker according to a second aspect embodiment of the present invention further includes: Once the de-icing process is complete, the second drive component 118 drives the second ice-making mold 106 to flip in the opposite direction relative to the first ice-making mold 104. Once the second ice-making mold 106 has completed its reverse flipping, the first driving component 116 drives the second ice-making mold 106 to switch from the separated position to the fitted position. Once the second ice mold 106 is in the fitting position, at least one of the water heating element 160, the first heating element, and the second heating element is turned on.

[0125] In one embodiment of the present invention, after the ice cube is successfully detached from the second ice-making mold 106, the second driving member 118 will be activated, causing the second ice-making mold 106 to flip in the opposite direction relative to the first ice-making mold 104.

[0126] After the second ice-making mold 106 is reversed and flipped, the first driving component 116 will be activated, driving the second ice-making mold 106 to switch from the separated position (i.e., the position separated from the first ice-making mold 104) back to the fitted position, in preparation for the next ice-making process.

[0127] After the second ice mold 106 returns to its fitted position, at least one of the following can be activated to prepare for the next ice-making process: water heater 160 (for heating the water required for ice making), first heater (for heating the first ice mold 104), and second heater (for heating the second ice mold 106). These heaters can preheat the ice mold and / or the water to ensure the smooth progress of the ice-making process.

[0128] By adding reverse flipping and position switching steps, the ice maker is ensured to quickly return to its initial state after each ice-making cycle, preparing for the next ice-making process and thus improving the continuity and efficiency of equipment operation. Precise control of each step's execution and status confirmation ensures the stability and reliability of the ice maker during operation, reducing downtime caused by improper operation or equipment malfunction. After the ice mold returns to its fitting position, the appropriate heating element is activated for preheating as needed, ensuring smooth ice-making while avoiding unnecessary energy waste. Automated control and precise status confirmation make the ice maker easier and faster to operate, enhancing the overall user experience.

[0129] A third aspect of the present invention also provides a refrigeration device, including a refrigeration chamber in which the ice maker described above is disposed.

[0130] According to a third aspect embodiment of the present invention, the refrigeration apparatus includes a refrigeration chamber in which the previously described ice maker is disposed. This design aims to integrate the ice-making function into the refrigeration apparatus, thereby providing users with a more convenient and efficient refrigeration and ice-making experience.

[0131] The refrigeration room provides a low-temperature environment to preserve food, beverages, or other items requiring refrigeration. An ice maker is located within the refrigeration room and connected to its refrigeration system to produce ice using the cold source provided by the system.

[0132] The refrigeration system of the refrigeration equipment works in tandem with the refrigeration system of the ice maker to ensure that while providing sufficient refrigeration space, ice cubes can also be produced efficiently.

[0133] In addition, refrigeration equipment can be equipped with a user interface to display status information of the refrigeration room and ice maker, such as temperature and ice-making progress.

[0134] By integrating the ice maker into the refrigeration system, the space in the refrigeration room is fully utilized, avoiding the need for additional space required to purchase a separate ice maker. The collaborative operation of the refrigeration system and the ice maker ensures an efficient refrigeration and ice-making process, reducing energy consumption and ice-making time. By integrating the ice maker, the refrigeration system not only has refrigeration capabilities but also ice-making functions, meeting diverse user needs.

[0135] According to one embodiment of the present invention, the refrigeration room includes: First refrigeration room 168; The second refrigeration room 170 has an ambient temperature lower than that of the first refrigeration room 168. The ice maker also includes an evaporator assembly 180, an ice mold assembly disposed in a first refrigeration chamber 168, and at least a portion of the evaporator assembly 180 disposed in a second refrigeration chamber 170.

[0136] See Figure 1 In one embodiment of the present invention, the refrigeration chamber is divided into two areas: a first refrigeration chamber 168 and a second refrigeration chamber 170, each of which performs different functions and achieves temperature control and heat exchange through a specific component, namely the evaporator assembly 180.

[0137] The first refrigeration chamber 168 is the main working area of ​​the ice maker, used to house the ice mold assembly. The ice mold assembly undergoes the ice-forming process here, with its temperature precisely controlled by the refrigeration system.

[0138] The ambient temperature of the second cooling chamber 170 is set lower than that of the first cooling chamber 168 to provide a lower temperature environment, which helps to improve the overall cooling efficiency. This is because the lower ambient temperature can accelerate heat transfer, allowing the evaporator assembly 180 to absorb and release heat more effectively.

[0139] The evaporator assembly 180 is used for heat absorption and release. In this embodiment, the evaporator assembly 180 is at least partially disposed within the second refrigeration chamber 170 to utilize the low-temperature environment of the second refrigeration chamber 170 and improve refrigeration efficiency. Simultaneously, the evaporator assembly 180 is also connected to the ice mold assembly within the first refrigeration chamber 168 to ensure that the ice mold assembly maintains a suitable temperature, thereby completing the ice block molding process.

[0140] By placing the evaporator assembly 180 at least partially within the second refrigeration chamber 170, where the ambient temperature is lower, the present invention enables more efficient heat transfer, thereby improving refrigeration efficiency. Due to this increased efficiency, the present invention achieves the same refrigeration effect while consuming less energy, thus optimizing energy consumption. By precisely controlling the temperature within the first refrigeration chamber 168, the present invention ensures that the ice mold assembly forms ice blocks under optimal conditions, thereby improving the quality and stability of the ice blocks. Optimized refrigeration efficiency and energy consumption help reduce the operating load on the equipment, thereby extending its overall lifespan. The structural design of the present invention allows for independent temperature control of the first refrigeration chamber 168 and the second refrigeration chamber 170, thereby improving the flexibility and adaptability of the equipment to meet different ice-making needs and environmental conditions.

[0141] According to one embodiment of the present invention, a spacer 172 is formed between the first refrigeration chamber 168 and the second refrigeration chamber 170, at least a portion of the ice maker is located in the spacer 172, and the spacer 172 having the ice maker is in fluid communication with the first refrigeration chamber 168 and the second refrigeration chamber 170.

[0142] See Figure 1 In one embodiment of the present invention, a partition area 172 is provided between the first refrigeration chamber 168 and the second refrigeration chamber 170. The partition area 172 not only provides installation space for some components of the ice maker, but also achieves fluid communication between the first refrigeration chamber 168 and the second refrigeration chamber 170 through a specific design. The design of the partition area 172 not only optimizes the internal structural layout of the ice maker, but also improves space utilization, making the entire ice maker more compact and efficient. Cold air can flow freely within the partition area 172, thereby achieving heat transfer and temperature control. Through this design, the temperature difference between the first refrigeration chamber 168 and the second refrigeration chamber 170 can be utilized more effectively to optimize cooling performance and energy consumption.

[0143] By designing the interval 172 region as fluidly connected to the first refrigeration chamber 168 and the second refrigeration chamber 170, this invention can more effectively utilize temperature differences and improve refrigeration efficiency. Due to the improved refrigeration efficiency, this invention can consume less energy while achieving the same refrigeration effect, thus optimizing energy consumption. The design of the interval 172 region not only provides installation space for some components of the ice maker but also optimizes the internal structural layout, making the entire ice maker more compact and efficient. By optimizing the refrigeration cycle and temperature control, this invention can reduce the operating load and failure rate of the equipment, thereby improving the reliability and stability of the equipment. This design allows the ice maker to better adapt to different environmental conditions and ice-making needs, improving the flexibility and adaptability of the equipment.

[0144] According to one embodiment of the present invention, a first air duct 174 is provided in the first refrigeration chamber 168, and a first air outlet is provided in the first air duct 174, with the ice mold assembly corresponding to the first air outlet; a second air duct 176 is provided in the second refrigeration chamber 170, and a second air outlet is provided in the second air duct 176, with the evaporator assembly 180 corresponding to the second air outlet.

[0145] See Figure 1 In one embodiment of the present invention, the first refrigeration chamber 168 serves as one of the main working areas of the ice maker. The first refrigeration chamber 168 is responsible for providing a low-temperature environment for the ice mold assembly to promote rapid and uniform ice formation. An optimized airflow structure, namely the first airflow duct 174, is designed within the first refrigeration chamber 168. The first airflow duct 174 is arranged around or above the ice mold assembly to ensure that cold air can flow evenly throughout the entire ice mold assembly area.

[0146] One or more first air outlets are provided on the first air duct 174, and the positions of the first air outlets are closely corresponding to the cooling requirements of the ice mold components. Cold air is precisely guided to the ice mold components through these air outlets, thereby accelerating heat transfer and promoting the formation of ice blocks.

[0147] Compared to the first cooling compartment 168, the second cooling compartment 170 has a lower ambient temperature and is primarily designed to provide a more efficient heat exchange environment for the evaporator assembly 180. Within the second cooling compartment 170, an optimized airflow structure, namely the second airflow duct 176, is also designed. The second airflow duct 176 is positioned around or above the evaporator assembly 180 to ensure sufficient heat exchange between the cool air and the evaporator assembly 180. One or more second air outlets are provided on the second airflow duct 176, the positions of which closely correspond to the heat exchange requirements of the evaporator assembly 180. Cool air is precisely guided to the evaporator assembly 180 through these air outlets, thereby enhancing heat exchange efficiency and improving cooling performance.

[0148] In this embodiment, the design of the first air duct 174 and the second air duct 176 not only takes into account the uniformity and efficiency of airflow, but is also closely linked to the refrigeration cycle. The six- or seven-year-old circulation path in the refrigeration equipment is matched with the layout of the air ducts to ensure that heat can be efficiently transferred from the ice mold assembly and the evaporator assembly 180 and discharged to the external environment through the condenser.

[0149] Furthermore, the design of the first air duct 174 and the second air duct 176 can also take noise control and energy efficiency optimization into account. Through a reasonable air duct layout and air outlet design, the noise generated during airflow can be reduced and the energy efficiency ratio can be improved, making the ice maker quieter and more energy-efficient during operation.

[0150] The optimized airflow design allows cold air to flow more evenly across the ice mold assembly and evaporator assembly 180, thereby improving cooling efficiency. The design of the first airflow 174 allows cold air to blow directly onto the ice mold assembly, accelerating heat transfer and shortening the ice-forming time. The design of the second airflow 176 helps the evaporator assembly 180 absorb heat more effectively, improving evaporator performance and further enhancing the cooling effect. The rational airflow layout and outlet design reduce noise generated during airflow, making the ice maker quieter during operation. Due to the improved cooling efficiency and optimized noise control, this invention achieves the same cooling effect while consuming less energy, thus optimizing energy consumption.

[0151] According to one embodiment of the present invention, the outer side of the ice maker is covered with a heat insulation layer 178, and the heat insulation layer 178 is provided with an air inlet corresponding to the first air outlet and the second air outlet.

[0152] See Figure 2 In one embodiment of the invention, the outer side of the ice maker is covered with an insulation layer 178, which is made of a material with good heat insulation and wear resistance. These materials can effectively reduce the loss of cold energy and prevent the intrusion of external heat, thereby maintaining the low temperature state of the internal space of the ice maker.

[0153] The insulation layer 178 not only improves the ice-making efficiency and reduces ice-making time, but also ensures stable temperature within the ice-making space. This helps improve the quality and consistency of the ice cubes while reducing energy consumption.

[0154] Air inlets corresponding to the first and second air outlets are provided on the insulation layer 178. These air inlets are carefully arranged to ensure that air can smoothly enter the ice maker and flow through the first air duct 174 and the second air duct 176.

[0155] The design of the air inlet can take into account the uniformity and efficiency of airflow. By using a reasonable air inlet size and location layout, it can be ensured that cold air can be evenly distributed into the first refrigeration chamber 168 and the second refrigeration chamber 170, thereby improving refrigeration efficiency.

[0156] The inclusion of insulation layer 178 and the optimized layout of the air inlet allow cold air to flow more evenly throughout the ice maker, thus improving cooling efficiency. This increased efficiency results in lower energy consumption while achieving the same cooling effect, optimizing energy usage. Insulation layer 178 ensures stable temperature within the ice-making space, contributing to improved ice quality and consistency. The optimized insulation layer 178 and air inlet design help reduce the equipment's operating load and failure rate, improving reliability and stability. Proper air inlet design and maintenance procedures facilitate easy cleaning and upkeep of the ice maker, extending its lifespan.

[0157] Finally, it should be noted that the above embodiments are only for illustrating the present invention and not for limiting the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art should understand that various combinations, modifications, or equivalent substitutions of the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention and should be covered within the scope of the claims of the present invention.
