[0026] See Figure 1 、 Figure 2 and Figure 3In one embodiment of the present invention, a thermoelectric ice maker for a laboratory is disclosed, which includes a body 10, a semiconductor refrigeration plate 20, a cover 30, a movable rod 40, a pusher 50, a sensor 60 and a controller 70.

[0027] Specifically, a mold cavity is formed on the housing 10, and the semiconductor cooling sheet 20 and the controller 70 are both disposed within the housing 10. The semiconductor cooling sheet 20 is disposed around the sidewall of the mold cavity, and the sensor 60 is disposed within the mold cavity for collecting temperature information of the sidewall of the mold cavity. The controller 70 is electrically connected to the semiconductor cooling sheet 20, the ejector 50, and the sensor 60.

[0028] Controller 70 receives temperature information collected by sensor 60 and controls the cooling or heating power of semiconductor refrigeration plate 20. Controller 70 also controls the opening and closing of pusher 50. Thus, in this embodiment, controller 70 automates the ice-making and ice-removing steps, improving the efficiency of the thermoelectric ice maker.

[0029] Specifically, the lid 30 disclosed in this embodiment is detachably connected to the body 10; the lid 30 covers the opening of the mold cavity. Before making ice, the lid 30 is lifted to fill the mold cavity with water; the lid 30 is then placed on the body 10 to seal the mold cavity.

[0030] Specifically, a center hole 31 is provided on the cover body 30; the movable rod body 40 is inserted into the center hole 31 and extends into the mold cavity; the pusher 50 is provided on the cover body 30; the pusher 50 is connected to the movable rod body 40, and is used to drive the movable rod body 40 to move back and forth along the axial direction of the center hole 31.

[0031] The thermoelectric ice maker disclosed in this embodiment comprises a body 10 and a cover 30, forming a closed mold cavity. By applying power to the semiconductor cooling element 20, cooling is achieved, causing the water in the mold cavity to freeze into ice cubes. Furthermore, a movable rod 40 is disposed within the mold cavity, and once the ice cubes are formed, they become integrally connected to the movable rod 40. During ice removal, a pusher 50 pushes the movable rod 40 outward, pulling the ice cubes and separating them from the mold cavity.

[0032] In addition, after the ice cubes are made, heat is provided by the semiconductor refrigeration sheet 20 to cause the outer surface of the ice cube to melt, thereby reducing the adhesion between the ice cube and the side walls and bottom walls of the mold cavity; at the same time, the real-time temperature of the side walls of the mold cavity is collected by the sensor 60, and the heating power of the semiconductor refrigeration sheet 20 is adjusted based on this, so that the outer surface of the ice cube melts quickly, while avoiding too much melting that affects the volume of the ice cube.

[0033] It can be seen that this embodiment can improve the ice-taking efficiency by accelerating the melting of ice cubes and simultaneously pushing the ice cubes, which is beneficial to improving the ice-making efficiency of the thermoelectric ice maker to meet the usage requirements in a laboratory working environment.

[0034] It should be noted that the controller 70 disclosed in this embodiment can be electrically connected to the semiconductor refrigeration plate 20, the pusher 50, and the sensor 60 through wires. As a conventional electrical connection method, the schematic diagrams of some wires are omitted in the drawings of the specification of this application, but this does not affect the understanding of the technical solution disclosed in this application by those skilled in the art.

[0035] like Figure 2 and Figure 3 As shown, as another embodiment of the present application, it is disclosed that the body 10 includes an outer box 12 and a partition 13 arranged in the outer box 12, the partition 13 abuts against the inner wall of the outer box 12, and divides the internal space of the outer box 12 into an upper chamber 121 and a lower chamber 122, and the controller 70 is arranged in the lower chamber 122; four inclined side walls 131 are protruding from the partition 13 on one side toward the upper chamber 121, and the four inclined side walls 131 together form the mold cavity; and four semiconductor refrigeration sheets 20 are provided, and the four semiconductor refrigeration sheets 20 are respectively attached to the four inclined side walls 131.

[0036] The partition 13 disclosed in this embodiment can be manufactured separately and then assembled with the outer case 12; alternatively, the partition 13 and the outer case 12 can be integrally formed to enhance the structural stability of the housing 10. The partition 13 conceals the lower chamber 122, hiding the controller 70 and minimizing contact. This also reduces the risk of liquid in the upper chamber 121 contacting electrical components, thereby enhancing the stability and safety of the device's internal circuitry.

[0037] In this embodiment, the upper chamber 121 is formed with four inclined sidewalls 131, forming a mold cavity. Preferably, the four inclined sidewalls 131 are all inclined outward, so that the bottom cross-sectional area of ​​the mold cavity is small and the top cross-sectional area is large, forming an overall inverted trapezoidal shape. This reduces friction between the ice cubes and the inclined sidewalls 131 when removing ice cubes, facilitating quick removal of the ice cubes.

[0038] In this embodiment, the semiconductor refrigeration sheet 20 is attached to the inclined side wall 131, specifically, the side of the inclined side wall 131 facing away from the mold cavity. The semiconductor refrigeration sheet 20 can be fixed by bonding, clamping, screwing, etc. At the same time, the semiconductor refrigeration sheet 20 can be connected to an external wire, passing through the partition 13 to connect to the controller 70 of the lower chamber 122. The four semiconductor refrigeration sheets 20 are provided so that the temperature on each inclined side wall 131 can be controlled to produce ice cubes with uniform density. At the same time, when taking ice, the melting speed of each side of the ice cube is consistent, avoiding the situation where one side of the ice cube melts while the other side has not melted, and preventing the ice cube from melting too much locally, affecting the volume of the finished ice cube.

[0039] For example Figure 2 and Figure 3 As shown, as another embodiment of the present application, four sensors 60 are provided, and the four sensors 60 are respectively provided on the four inclined side walls 131. By providing a sensor 60 on each inclined side wall 131, the four semiconductor refrigeration plates 20 can be controlled separately based on the temperature information collected by the four sensors 60, thereby improving the temperature control accuracy and facilitating accurate control of the ice making time.

[0040] like Figure 1 and Figure 3 As shown, as another embodiment of the present application, it is disclosed that the side wall of the outer box 12 is provided with heat dissipation holes 123, and the heat dissipation holes 123 are arranged directly opposite the semiconductor cooling plate 20. The semiconductor cooling plate 20 disclosed in this embodiment makes ice using the thermoelectric effect. When powered on, one side of the semiconductor cooling plate 20 absorbs heat and the other side releases heat. The side with a lower surface temperature is brought closer to the mold cavity to reduce the temperature inside the mold cavity. At the same time, the surface temperature of the side of the semiconductor cooling plate 20 facing away from the mold cavity is higher, so the heat dissipation holes 123 are provided accordingly, which is conducive to accelerating heat dissipation and preventing heat from accumulating in the upper chamber 121, thereby preventing the ice making effect from being affected.

[0041] like Figure 4 As shown, as another embodiment of the present application, the pusher 50 is disclosed to include an annular shell 51, a driving member 52, a multi-stage telescopic rod 53, a movable bottom plate 54, an elastic member 55 and a movable top plate 56.

[0042] In this embodiment, the annular housing 51 is connected to the cover 30 and is sleeved onto the movable rod 40. The interior of the annular housing 51 is hollow, forming an annular cavity 511. The annular housing 51 protects and shields the driving member 52, the multi-stage telescopic rod 53, the movable bottom plate 54, the elastic member 55, and the movable top plate 56.

[0043] Specifically, the driving member 52 is disposed within the annular cavity 511 and fixed to the bottom surface of the annular cavity 511. The driving member 52 is electrically connected to the controller 70. The multi-stage telescopic rod 53 is in transmission connection with the driving member 52, so that the driving member 52 can drive the multi-stage telescopic rod 53 to extend or retract. The extension direction of the multi-stage telescopic rod 53 is parallel to the axial direction of the movable rod body 40.

[0044] Specifically, the movable bottom plate 54, the elastic member 55 and the movable top plate 56 are stacked in sequence on the multi-stage telescopic rod 53; and the movable bottom plate 54, the elastic member 55 and the movable top plate 56 are all sleeved on the movable rod body 40; the movable bottom plate 54 is connected to the multi-stage telescopic rod 53, and the movable top plate 56 is clamped with the movable rod body 40; the driving member 52 is used to drive the multi-stage telescopic rod 53 to extend, so as to push the movable bottom plate 54 to squeeze the elastic member 55.

[0045] In summary, the working principle of the pusher 50 disclosed in this embodiment is: the driving member 52 drives the multi-stage telescopic rod 53, which in turn drives the movable bottom plate 54 to rise, squeezes the elastic member 55, accumulates elastic potential energy, and continuously generates thrust on the movable top plate 56; the movable top plate 56 is snap-connected with the movable rod body 40 and connected as one body, so the thrust on the movable top plate 56 can be regarded as a thrust on the movable rod body 40 and the ice cube, pushing the ice cube to produce a movement trend of separation from the mold cavity.

[0046] It can be seen that the pusher 50 provided in this embodiment can continuously generate thrust until the ice cubes are separated from the mold cavity, which is beneficial to shortening the ice removal time.

[0047] Specifically, as another embodiment of the present application, the driving member 52 includes any one of a hydraulic pump, a motor, and a cylinder; or the elastic member 55 is any one of a compression spring, a disc spring, and a rubber spring. Furthermore, any one of a hydraulic pump, a motor, and a cylinder can be used as the driving member 52, and any one of a compression spring, a disc spring, and a rubber spring can be used as the elastic member 55.

[0048] The driving member 52 disclosed in this embodiment is used to push the multi-stage telescopic rod 53 and continuously provide thrust. Therefore, it can be driven by hydraulic pressure, pneumatic pressure, or electricity to provide continuous pressure. The elastic member 55 disclosed in this embodiment is used to store and release elastic potential energy and is always in a compressed state. Using a compression-resistant elastic member 55 such as a compression spring, disc spring, or rubber spring can extend the service life and increase the stability of the structure.

[0049] like Figure 1 and Figure 2As shown, as another embodiment of the present application, a card slot is provided on the side of the cover body 30 facing the mold cavity, and the card slot is provided around the center hole 31; the thermoelectric ice maker includes an elastic support member 80 and a push plate 90, and the elastic support member 80 and the push plate 90 are both mounted on the movable rod body 40, and one end of the elastic support member 80 is inserted into the card slot, and the other end is in contact with the push plate 90; the push plate 90 is engaged with the movable rod body 40.

[0050] The push plate 90 disclosed in this embodiment is arranged on the side of the cover body 30 facing the mold cavity, and the support force is provided by the elastic support member 80. The elastic support member 80 can be a compression spring, a disc spring, etc. During the ice-taking process, the movable rod body 40 moves in the direction away from the mold cavity, and the pusher 50 overcomes the support force of the elastic support member 80 and pulls the movable rod body 40. After the ice is taken, the pusher 50 is closed, and under the thrust of the elastic support member 80, the movable rod body 40 can move in the opposite direction, thereby returning to the original position, so that the next cycle of ice-making can be carried out directly, thereby shortening the ice-making cycle.

[0051] For example Figure 2 As shown, as another embodiment of the present application, the controller 70 is disclosed to include a printed circuit board 71, a power supply 72 and a switch 73, wherein the power supply 72 is electrically connected to the printed circuit board 71 for providing electrical energy; the switch 73 is electrically connected to the printed circuit board 71 for opening or closing the circuit; and the semiconductor refrigeration plate 20, the pusher 50 and the sensor 60 are all electrically connected to the printed circuit board 71.

[0052] The power supply 72 disclosed in this embodiment can provide electrical energy, achieving self-powered operation, making the thermoelectric ice maker more convenient to use without requiring an external power supply 72 cable. The switch 73 disclosed in this embodiment includes, but is not limited to, a mechanical switch 73 or an electronic switch 73 controlled by Bluetooth, Wi-Fi, or the like. Using the switch 73 to control the opening and closing of the circuit helps conserve energy and increase safety.

[0053] For example Figure 2 As shown, as another embodiment of the present application, the thermoelectric ice maker is disclosed to include a water hardness detection probe 100 arranged on the bottom surface of the mold cavity, and the water hardness detection probe 100 is externally connected to a detection terminal for collecting hardness information of the water in the mold cavity.

[0054] The thermoelectric ice maker disclosed in this embodiment is used in a laboratory environment. Purified water, tap water, or an aqueous solution may be added. Therefore, the ice-making time required varies depending on the water quality. By providing a water hardness detection probe 100, the water added to the mold cavity is tested and the test results are transmitted to an external detection terminal. Based on these test results, the ice-forming time can be determined. This means that different cooling times can be set before ice-making to ensure optimal ice formation.

[0055] As another embodiment of the present application, a control method for a thermoelectric ice maker for a laboratory is also disclosed, which is applicable to any of the above-mentioned thermoelectric ice makers for a laboratory.

[0056] The control method of the thermoelectric ice maker for a laboratory provided by the embodiment of the present invention can be applied to Figure 5 In the application environment shown, the terminal 102 communicates with the server 104 via a network. The data storage system can store data that the server 104 needs to process. The data storage system can be integrated on the server 104, or placed on the cloud or other network servers; the control method for the thermoelectric ice maker used in the laboratory can be executed by the terminal 102 or the server 104, or can be executed collaboratively by the terminal 102 and the server 104. Of course, the control method for the thermoelectric ice maker used in the laboratory of this embodiment can also be implemented based on the printed circuit board 71 of the thermoelectric ice maker itself.

[0057] The terminal 102 may be a smartphone, tablet computer, laptop computer, desktop computer, smart speaker, smart watch, IoT device, or portable wearable device. IoT device may be a smart speaker, smart TV, smart air conditioner, or smart car device. Portable wearable device may be a smart watch, smart bracelet, or head-mounted device.

[0058] The server 104 may be an independent physical server or a service node in a blockchain system, where each service node in the blockchain system forms a peer-to-peer network.

[0059] In addition, server 104 can also be a server cluster composed of multiple physical servers, and can be a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, content delivery networks (CDNs), and big data and artificial intelligence platforms.

[0060] The terminal 102 and the server 104 can be connected via Bluetooth, USB (Universal Serial Bus) or network communication connection methods, and the present invention does not limit this.

[0061] like Figure 6 As shown, the control method disclosed in this embodiment includes: Step S10, collecting demoulding instructions; Step S20: based on the demoulding instruction, the ejector 50 is started and power is supplied to the semiconductor cooling plate 20, while real-time temperature information on the side wall of the mold cavity is collected; Step S30: generating an adjustment instruction based on the real-time temperature information; Step S40, fine-tuning the current value of the semiconductor refrigeration plate 20 based on the adjustment instruction; Step S50: When the stroke of the pusher 50 reaches the maximum value, a termination instruction is generated; Step S60: power off the semiconductor refrigeration plate 20 based on the termination instruction.

[0062] The demoulding instruction disclosed in this embodiment is an instruction to start the ice removal process. After receiving the demoulding instruction, the controller 70 enters the ice removal program, starts the pusher 50 and the semiconductor refrigeration plate 20, heats the ice cubes, and pushes them at the same time. In addition, the temperature information is collected during the ice removal process to ensure that the surface temperature of the semiconductor refrigeration plate 20 is appropriate, to prevent the temperature of the side wall of the mold cavity from being too high and melting too much ice cubes; and to prevent the temperature from being too low and affecting the speed of ice cube detachment. When the pusher 50 reaches its maximum stroke, the ice cube moves a maximum distance and separates from the mold cavity. At this time, the billiards and semiconductor refrigeration plate 20 can be turned off to complete the ice removal operation.

[0063] It can be seen that the control method disclosed in this embodiment can accurately and quickly complete the ice-taking operation, improve the ice-making efficiency of the ice-making machine, and further improve the production efficiency of ice cubes.

[0064] In some embodiments, a terminal is provided, whose internal structure diagram can be as follows: Figure 7As shown. The terminal includes a processor, memory, input / output interface, communication interface, display unit and input device. The processor, memory and input / output interface are connected via a system bus, and the communication interface, display unit and input device are connected to the system bus via the input / output interface.

The communication interface of the terminal is used to communicate with external terminals in a wired or wireless manner. The wireless manner can be achieved through WIFI, mobile cellular network, NFC (near field communication) or other technologies.

[0065] When executed by a processor, the computer program implements a control method for a thermoelectric ice maker for a laboratory.
