[0002] As people's living standards continue to improve, adding ice to various alcoholic beverages to make chilled drinks has become a common practice, resulting in a growing demand for ice-making equipment. In existing technologies, some ice-making devices, including an ice box and an evaporator, involve introducing a low-temperature medium into the evaporator. The evaporator exchanges heat with the ice box, lowering the temperature of the liquid inside and forming ice. During de-icing, a high-temperature medium is introduced into the evaporator, raising the temperature of the ice box and causing the ice to separate from it. However, this de-icing process often results in broken ice. Utility Model Content

[0008] In some feasible embodiments, the ice box also includes a lid, which surrounds the ice mold to form an ice-making cavity, and an evaporator is coiled around the outer periphery of the ice mold, with the evaporator in contact with the side of the ice mold away from the lid.

[0009] In some feasible embodiments, the ice box also includes a rear shell and a front baffle, the front baffle having an opening, a receiving space between the rear shell and the front baffle, at least a portion of the evaporator structure and the ice mold being located within the receiving space, and the ice-making cavity being exposed through the opening in the front baffle.

[0021] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0022] To illustrate the technical solutions described in this application, the following detailed description is provided in conjunction with specific drawings and embodiments.

[0023] like Figure 1As shown in the embodiment of this application, an ice-making device is proposed, including: a compressor 100, a condenser 200, a refrigeration throttling structure 300, an evaporator 400, and a three-way structure 500. The three-way structure 500 includes a first port 510, a second port 520, and a third port 530. The outlet of the compressor 100 is connected to the inlet of the condenser 200, the outlet of the condenser 200 is connected to the first port 510, the second port 520 is connected to the inlet of the refrigeration throttling structure 300, the outlet of the refrigeration throttling structure 300 is connected to the inlet of the evaporator 400, the third port 530 is connected to the inlet of the evaporator 400, and the outlet of the evaporator 400 is connected to the inlet of the compressor 100. The ice-making device includes an ice-making process and an ice-removing process. In the ice-making process, the first port 510 and the second port 520 are connected; in the ice-removing process, the first port 510 and the third port 530 are connected.

[0024] The three-way structure 500 is a one-in-two-out structure, with the first port 510 being the inlet and the second port 520 and third port 530 being the outlets. In one configuration, the three-way structure 500 may include a three-way valve, which includes a valve seat and a valve core. The valve seat includes the first port 510, the second port 520, and the third port 530. The valve core is installed within the valve seat, and its movement changes the connection state of the valve seat. In the ice-making process, the valve core is in a first position, such that the first port 510 is connected to the second port 520, and disconnected from the third port 530. In the de-icing process, the valve core moves to a second position, such that the first port 510 is connected to the third port 530, and disconnected from the second port 520.

[0025] In another configuration, the three-way structure 500 may include a three-way pipe, a first valve, and a second valve. The three-way pipe includes a first port 510, a second port 520, and a third port 530. The first valve is installed at the second port 520, and the second valve is installed at the third port 530. During the ice-making process, the first valve is open and the second valve is closed, allowing liquid entering through the first port 510 to flow out through the second port 520. During the de-icing process, the second valve is open and the first valve is closed, allowing liquid entering through the first port 510 to flow out through the third port 530.

[0026] In the ice-making process, the first port 510 is connected to the second port 520. The compressor 100 outputs high-temperature, high-pressure gas to the condenser 200. The condenser 200 cools the high-temperature, high-pressure gas into a liquid state and then outputs it to the refrigeration throttling structure 300. The refrigeration throttling structure 300 further cools the liquid and then outputs it to the evaporator 400, where ice-making is performed. In the de-icing process, the first port 510 is connected to the third port 530. The compressor 100 outputs high-temperature, high-pressure gas to the condenser 200. The condenser 200 cools the high-temperature, high-pressure gas into a liquid state and then outputs it to the evaporator 400. The temperature of the liquid directly output from the condenser 200 is higher than that output through the refrigeration throttling structure 300. Therefore, de-icing can be performed using the liquid output from the condenser 200. Since the temperature difference between the liquid output from the condenser 200 and the liquid output from the refrigeration throttling structure 300 is relatively small, the de-icing process is gentler, and the possibility of ice breakage is relatively smaller.

[0027] In some feasible embodiments, the ice-making equipment also includes a controller. The condenser 200 includes a condenser tube 220 and a fan 210. The fan 210 is installed on one side of the condenser tube 220 and is used to cool the condenser tube 220. The fan 210 includes a first working mode and a second working mode. The power of the first working mode is greater than the power of the second working mode. The controller is used to control the fan 210 to switch to the first working mode during the ice-making process and to control the fan 210 to switch to the second working mode during the de-icing process.

[0028] When the fan 210 has a relatively high power, its cooling effect on the condenser 220 is relatively good, resulting in a relatively low temperature for the liquid output from the condenser 220. This liquid is further cooled by the refrigeration throttling structure 300, reaching an even lower temperature, thus ensuring a relatively low temperature of the liquid supplied to the evaporator 400 and increasing the ice-making efficiency of the evaporator 400. When the fan 210 has a relatively low power, its cooling effect on the condenser 220 decreases, resulting in a relatively higher temperature for the liquid output from the condenser 220. This liquid is then supplied to the evaporator 400 for de-icing. The temperature range of the liquid supplied to the evaporator 400 during the de-icing process can be adjusted to some extent by regulating the power of the fan 210, making the liquid temperature more suitable for de-icing, thereby achieving higher de-icing efficiency and a lower risk of ice breakage.

[0029] In some feasible embodiments, the ice-making equipment also includes a controller. The condenser 200 includes a condenser tube 220 and a fan 210. The fan 210 is installed on one side of the condenser tube 220 and is used to cool the condenser tube 220. The controller is connected to the fan 210 and is used to control the power of the fan 210. A temperature sensor is provided at the inlet of the evaporator 400 and is connected to the controller. During the de-icing process, if the temperature of the temperature sensor is greater than a first threshold, the controller controls the power of the fan 210 to increase.

[0030] In this configuration, the temperature at the inlet of the evaporator 400 can be detected by a temperature sensor, thereby determining the temperature of the liquid entering the evaporator 400. If the liquid temperature is too high, the ice will be easily broken during de-icing. The temperature of the liquid entering the evaporator 400 can be adjusted to some extent by controlling the power of the fan 210. The first threshold is the highest value or close to the highest value in the preferred de-icing temperature range. For example, if the preferred de-icing temperature range is between 1°C and 5°C, then the first threshold can be 4°C or 5°C.

[0031] In some feasible embodiments, the controller can also be used to reduce the power of the fan 210 when the temperature of the temperature sensor is lower than a second threshold during the de-icing process. In this configuration, the controller can more precisely control the temperature of the liquid entering the evaporator 400 for de-icing to be more suitable. The first threshold is the lowest value or close to the lowest value in the preferred de-icing temperature range. For example, if the preferred de-icing temperature range is between 1°C and 5°C, the first threshold can be 1°C or 2°C. By reducing the power of the fan 210, the temperature of the liquid entering the evaporator 400 can be increased, thereby accelerating the de-icing efficiency.

[0032] As can be seen from the above, the coordinated control of the controller, temperature sensor and fan 210 can ensure that the temperature of the liquid entering the evaporator 400 for de-icing is within a more preferred temperature range, so as to reduce the possibility of ice breaking during de-icing while ensuring relatively high de-icing efficiency.

[0033] In one specific example, the controller may include a microcontroller, a PLC (Programmable Logic Controller), or a microcontroller. The controller has input ports and output ports; the temperature sensor is connected to the input port, and the drive unit of the fan 210 is connected to the output port. For example, the fan 210 may be electric, and if the drive unit of the fan 210 is a motor, then the motor is connected to the controller's output port. Signal transmission between the temperature sensor and the controller, and between the drive unit of the fan 210 and the controller, can be achieved via wired or wireless connections, respectively.

[0034] The refrigeration throttling structure 300 may include a capillary tube or an expansion valve. In some feasible embodiments, the refrigeration throttling structure 300 includes a capillary tube. The capillary tube is a long, thin, hollow tube with a fixed inner diameter, such as a copper tube. The inner diameter of the capillary tube is extremely small (e.g., 0.5 mm to 2 mm). In the refrigeration process, the compressor 100 compresses the refrigerant into a high-temperature, high-pressure gas, and the condenser 200 cools the high-temperature, high-pressure gas into a liquid state. When the refrigerant flows through the capillary tube, the flow cross-sectional area suddenly shrinks, and the flow resistance increases. The high-pressure liquid refrigerant must overcome the frictional resistance of the capillary tube wall and the viscous resistance of the fluid itself to flow forward. In the process of overcoming the resistance, the refrigerant consumes its own pressure energy, and the pressure drops significantly. When the refrigerant pressure drops below the boiling point pressure of the refrigerant in the current environment, it will transform from a liquid state to a gas state (i.e., "vaporize"). The vaporization process requires heat absorption. The refrigerant absorbs heat from itself to meet the vaporization requirements, causing its temperature to drop rapidly during vaporization. Ultimately, a low-pressure, low-temperature gas-liquid mixture of refrigerant is formed at the capillary tube outlet. At this point, the capillary tube cooling process is complete: the original high-pressure liquid refrigerant becomes a low-temperature, low-pressure gas-liquid mixture after passing through the capillary tube, possessing the refrigeration capability to absorb heat and continue vaporizing after entering the evaporator at 400°C.

[0035] Since capillary tubes do not contain moving parts, they have relatively high reliability and relatively low production and maintenance costs. Capillary tubes are small in size and easy to arrange; their length and curvature can be flexibly configured according to the internal space of the ice-making equipment, occupying little space and making them more suitable for miniaturized and compact ice-making equipment.

[0036] In some feasible implementations, such as Figures 2 to 4 As shown, the ice-making equipment also includes an ice box, which comprises an ice mold 610, with an evaporator 400 in contact with the outer wall of the ice mold 610. The ice mold 610 is used to form ice cubes, and the shape of the inner cavity of the ice mold 610 is related to the shape of the ice cubes it produces. The evaporator 400 is located outside the ice mold 610. The evaporator 400 cools or heats the ice mold 610 through contact with it. During the cooling process of the evaporator 400, the temperature of the liquid environment inside the ice mold 610 decreases, thereby forming ice cubes. During the heating process of the evaporator 400, the ice cubes inside the ice mold 610 melt slightly near the outer surface of the ice mold 610, causing the ice cubes to separate from the ice mold 610.

[0037] In some feasible embodiments, the ice box also includes a lid 630, which and the ice mold 610 surround to form an ice-making cavity 620, and an evaporator 400 is coiled around the outer periphery of the ice mold 610, with the evaporator 400 in contact with the side of the ice mold 610 away from the lid 630.

[0038] In some embodiments, a pipe can be provided inside the ice mold 610 to introduce liquid into the ice mold 610, so that the liquid inside the ice mold 610 freezes into ice. In other feasible embodiments, the ice-making device also includes a spray structure 700 to spray liquid into the ice mold 610, so that the liquid inside the ice mold 610 freezes into ice. In one example, the spray device can be provided on the cover 630, one side of the cover 630 is hinged to the ice mold 610, and the other side of the cover 630 is connected to the ice mold 610 via an opening and closing control structure. The opening and closing control structure is used to control the rotation of at least one of the cover 630 and the ice mold 610, so that the cover 630 and the ice mold 610 switch between a closed state and an open state. In the closed state, the cover 630 covers the ice mold 610, and the ice-making cavity 620 is in a closed state. In the open state, the cover 630 is rotated at a certain angle relative to the ice mold 610 so that the demolded ice can be discharged from the ice mold 610.

[0039] In some alternative embodiments, the ice box includes a first mold and a second mold. The first mold has a first chamber, and the second mold has a second chamber. The first mold and the second mold are connected so that the first chamber and the second chamber communicate to form an ice-making cavity 620. A spray structure 700 is installed on either the first mold or the second mold, or it can be installed on both the first mold and the second mold. The ice box can be used to make square ice or spherical ice. To make square ice, both the first chamber and the second chamber can be square chambers. When the first mold and the second mold are connected, the first chamber and the second chamber communicate to form a larger square chamber, which is the ice-making cavity 620, and square ice can be formed within the ice-making cavity 620. To make spherical ice, both the first chamber and the second chamber can be hemispherical chambers. When the first mold and the second mold are connected, the first chamber and the second chamber communicate to form a spherical chamber, which is the ice-making cavity 620, and spherical ice can be formed within the ice-making cavity 620.

[0040] In one example, there can be multiple ice-making chambers 620, arranged in an array within an ice box. The arrangement of multiple ice-making chambers 620 allows for the production of multiple ice cubes in a single ice-making process. The spray structure 700 includes a spray pipe 710 and multiple nozzles 720. The nozzles 720 are connected to the spray pipe 710 and face the ice-making chambers 620. When there are multiple ice-making chambers 620, at least one nozzle 720 can be provided for each ice-making chamber 620. Exemplarily, the number of nozzles 720 is the same as the number of ice-making chambers 620, with each nozzle 720 corresponding to one of the multiple ice-making chambers 620. All nozzles 720 are mounted on the spray pipe 710 and are connected to it. In this arrangement, liquid is delivered to the multiple ice-making chambers 620 through multiple nozzles 720, resulting in higher liquid delivery efficiency, higher uniformity, and higher ice-making efficiency. In other examples, more nozzles 720 can be provided for each ice-making cavity 620. For example, two nozzles 720 can be provided for one ice-making cavity 620. The correspondence between the number of ice-making cavities 620 and the number of nozzles 720 can be specifically set according to the size of the ice-making cavity 620 and the spray range of the nozzles 720.

[0041] like Figure 2 and Figure 3 As shown, the ice box also includes a rear shell 640 and a front baffle 660. The front baffle 660 has an opening, and there is a receiving space between the rear shell 640 and the front baffle 660. At least a portion of the structure of the evaporator 400 and the ice mold 610 are located within this receiving space. The rear shell 640 covers the outer periphery and rear side of the ice mold 610. The ice mold 610 is connected to the front baffle 660, and the ice-making cavity 620 is exposed through the opening of the front baffle 660. The front baffle 660 and the rear shell 640 are connected, and the connection between the front baffle 660 and the rear shell 640 can be detachable or non-detachable. Exemplarily, the front baffle 660 and the rear shell 640 can be connected by snap-fit, by bolts, or by adhesive. The separate arrangement of the front baffle 660 and the rear shell 640 facilitates the installation of the evaporator 400 and the ice mold 610 into the receiving space during assembly. In some examples, at least a portion of the structure of the evaporator 400 is coiled around the axial sides and bottom of the ice mold 610, meaning that the outer periphery and bottom surface of the ice mold 610 are in contact with the evaporator 400, resulting in a relatively large contact area. The rear shell 640 serves to shield and protect the evaporator 400. For example... Figure 3 As shown, a support post 660 is provided on the rear side of the front baffle 660. The support post 660 contacts the rear shell 640, and the provision of the support post 660 increases the support stability between the front baffle 660 and the rear shell 640. When the ice box includes a cover 630, the cover 630 covers the front baffle 660, completely blocking the opening of the front baffle 660, thereby covering the ice-making cavity 620 and sealing the ice-making cavity 620.

[0042] like Figure 5 As shown, in some feasible embodiments, the ice-making equipment also includes a filter 800, which is disposed between the compressor 100 and the condenser 200.

[0043] like Figure 6 As shown, in some feasible embodiments, the ice-making device further includes a filter 800 disposed between the second port 520 and the refrigeration throttling structure 300.

[0044] like Figure 7 As shown, in some feasible embodiments, the ice-making equipment also includes a filter 800, which is disposed between the condenser 200 and the first port 510.

[0045] Filter 800 may include one or more filter elements. Refrigerant is filtered as it passes through these elements. If particulate matter or impurities are present in the refrigerant, they will be filtered out, resulting in a higher level of cleanliness of the refrigerant after filtration by filter 800. This protects downstream components, extends the overall lifespan of the ice-making equipment, and reduces maintenance frequency. When filter 800 is installed upstream of condenser 200 (i.e., between compressor 100 and condenser 200), it protects condenser 200 and reduces the risk of corrosion and blockage in the condenser 200 piping. When filter 800 is installed between the second port 520 and the refrigeration throttling structure 300, it protects the refrigeration throttling structure 300 and reduces the risk of blockage. When filter 800 is installed between condenser 200 and the first port 510, it protects the tee and its downstream piping, the refrigeration throttling structure 300, and the evaporator 400, reducing the risk of internal corrosion and pipe blockage.

[0046] The ice-making equipment provided in this application can be an independent ice-making device, such as an embedded ice-making device, a tabletop ice-making device, a portable ice-making device, etc., or it can be an ice-making device applied to other devices, such as an ice-making device applied to appliances such as refrigerators and water dispensers.

[0047] The above-disclosed embodiments are merely preferred embodiments of this application and should not be construed as limiting the scope of this application. Therefore, any equivalent variations made in accordance with the claims of this application shall still fall within the scope of this application.
