Description

Technical Field

[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 technology, ice-making equipment includes an ice box and an evaporator. During ice making, a low-temperature medium is introduced into the evaporator, and the evaporator exchanges heat with the ice box, thereby lowering the temperature of the liquid inside the ice box to form ice. During de-icing, a high-temperature medium is introduced into the evaporator, which raises the temperature of the ice box, causing the ice to separate from the ice box, thus achieving de-icing. However, the de-icing speed described above is relatively slow. Utility Model Content

[0003] In view of this, this application provides an ice-making device to solve the technical problem of slow ice removal speed in existing ice-making devices.

[0007] In some alternative embodiments, the refrigeration device includes a heating end, and the ice-making equipment further includes a heat exchange tank for holding liquid. At least a portion of the heating end is located in the heat exchange tank so that the liquid in the heat exchange tank is heated to a second liquid. The heat exchange tank is connected to a de-icing pipeline and is used to supply the second liquid to the de-icing pipeline.

[0008] In some alternative embodiments, the refrigeration device includes a heating end, an ice removal line in contact with the heating end, and a portion of the ice removal line is arranged around the outer periphery of the heating end.

The ice-making pipeline supplies a first liquid to the spray structure, which sprays the first liquid into the ice box, causing the first liquid to form ice cubes inside the ice box. During the de-icing process, the de-icing pipeline supplies a second liquid to the spray structure, which sprays a second liquid with a relatively higher temperature onto the surface of the ice cubes inside the ice box, thereby separating the ice cube surface from the ice box and achieving the de-icing process.

[0018] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the structure or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[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] First Embodiment like Figures 1 to 3 As shown in the figure, this application provides an ice-making device, including: an ice box 300, a spray structure 200, a refrigeration device 100, an ice-making pipeline 400, and an ice-removing pipeline 500, wherein: The refrigeration device 100 is used to cool the ice box 300; the ice box 300 includes an ice-making chamber 310, and a spray structure 200 is installed on the ice box 300 for spraying liquid into the ice-making chamber 310; the ice-making pipe 400 and the de-icing pipe 500 are respectively connected to the spray structure 200, the ice-making pipe 400 is used to provide a first liquid to the spray structure 200 to make ice, and the de-icing pipe 500 is used to provide a second liquid to the spray structure 200 to de-ic, the temperature of the second liquid is higher than that of the first liquid.

[0024] The first liquid and the second liquid can be the same type of liquid, with the second liquid having a higher temperature than the first liquid. Alternatively, the first liquid and the second liquid can be different types of liquid, with the second liquid having a higher temperature than the first liquid. For example, the first liquid and the second liquid can be the same, both being water or other beverages (e.g., fruit juice). In another example, the first liquid is fruit juice, and the second liquid is water.

[0025] Of the first and second liquids, the first liquid has a relatively lower temperature. It enters the ice-making chamber 310 via the spray structure 200 and freezes into ice blocks under the action of the refrigeration device 100. Due to its relatively low temperature, the freezing speed is relatively faster. Conversely, the second liquid has a relatively higher temperature. It also enters the ice-making chamber 310 via the spray structure 200. Since ice blocks have already formed in the chamber, the second liquid sprays onto the surface of the ice blocks, causing slight melting and separating the ice blocks from the inner wall of the ice-making chamber 310. This allows the ice blocks to detach from the ice-making chamber 310, thus achieving the de-icing operation. Because the second liquid is sprayed directly onto the surface of the ice blocks without heat conduction through the ice box 300, the de-icing speed is faster and the efficiency is higher.

[0026] In one example, there can be multiple ice-making chambers 310, arranged in an array within the ice box 300. The arrangement of multiple ice-making chambers 310 allows for the production of multiple ice cubes in a single ice-making process. The spray structure 200 includes a spray pipe 210 and nozzles 210. The nozzles 210 are connected to the spray pipe 210 and face the ice-making chambers 310. When there are multiple ice-making chambers 310, at least one nozzle 210 can be provided for each ice-making chamber 310. Exemplarily, the number of nozzles 210 is the same as the number of ice-making chambers 310, with each nozzle 210 corresponding to one of the multiple ice-making chambers 310. All nozzles 210 are mounted on the spray pipe 210 and are connected to it. In this arrangement, liquid is delivered to the multiple ice-making chambers 310 through multiple nozzles 210, resulting in higher liquid delivery efficiency, higher uniformity, and higher ice-making efficiency.

[0027] The spray pipe 210 is connected to both the ice-making pipe 400 and the de-icing pipe 500. In one configuration, the ice-making pipe 400 and the de-icing pipe 500 are further connected to different areas of the spray pipe 210. Both the ice-making pipe 400 and the de-icing pipe 500 are equipped with solenoid valves. During ice-making, the solenoid valve on the de-icing pipe 500 is closed, and the solenoid valve on the ice-making pipe 400 is open. During de-icing, the solenoid valve on the ice-making pipe 400 is closed, and the solenoid valve on the de-icing pipe 500 is open. For example, one end of the spray pipe 210 can be connected to the ice-making pipe 400, and the other end can be connected to the de-icing pipe 500.

[0028] In another configuration, a three-way valve 230 is installed on the spray pipe 210. The other two ports of the three-way valve 230 are connected to the ice-making pipe 400 and the de-icing pipe 500, respectively. During ice making, the valve core of the three-way valve 230 moves to connect the spray pipe 210 with the ice-making pipe 400, while disconnecting the spray pipe 210 from the de-icing pipe 500. During de-icing, the valve core of the three-way valve 230 moves to connect the spray pipe 210 with the de-icing pipe 500, while disconnecting the spray pipe 210 from the ice-making pipe 400.

[0029] In some alternative implementations, such as Figure 3 As shown, the ice box 300 includes a bottom mold 320 and a cover 330. An ice-making cavity 310 is disposed on the bottom mold 320, and a spray structure 200 is installed on the cover 330. The cover 330 closes to the ice-making cavity 310. Exemplarily, the bottom mold 320 has an ice-making cavity 310 on the side facing the cover 330. The ice-making cavity 310 is a groove on the bottom mold 320 and has an opening. The cover 330 closes to this opening, thereby sealing the ice-making cavity 310. When the cover 330 closes to the bottom mold 320, the cover 330 seals the ice-making cavity 310. The spray structure 200 on the cover 330 sprays a first liquid into the ice-making cavity 310. The first liquid enters the ice-making cavity 310, and under the action of the refrigeration device 100, the first liquid freezes inside the ice-making cavity 310. After ice making is completed, a relatively high-temperature second liquid is sprayed into the ice-making chamber 310 through the spray structure 200 to perform the de-icing operation. After the cover 330 is opened, the de-iced ice can be poured out from the ice-making chamber 310.

[0030] In some alternative embodiments, the ice box 300 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 310. A spray structure 200 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 300 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 310, and square ice can be formed within the ice-making cavity 310. To make spherical ice using ice box 300, 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 are connected to form a spherical chamber, which is the ice-making chamber 310, and spherical ice can be formed in the ice-making chamber 310.

[0031] In some alternative implementations, such as Figure 4As shown, the refrigeration device 100 includes an evaporator 110, a compressor 120, and a condenser 130. The outlet of the compressor 120 is connected to the inlet of the condenser 130, the outlet of the condenser 130 is connected to the inlet of the evaporator 110, and the outlet of the evaporator 110 is connected to the inlet of the compressor 120. The evaporator 110 is in contact with the ice box 300. During the ice-making process, the compressor 120 starts, compresses the refrigerant into a high-temperature, high-pressure gas, and delivers it to the condenser 130. The condenser 130 cools the high-temperature, high-pressure gas, turning it into a low-temperature liquid, which is then delivered to the evaporator 110. The evaporator 110 exchanges heat with the ice box 300, lowering the temperature of the ice box 300 and the liquid inside it. In this configuration, the refrigeration device 100, including the compressor 120, condenser 130, and evaporator 110, can provide a large cooling capacity, quickly freezing the liquid in the ice box 300 into ice. This allows the ice-making equipment to meet the needs of various scales, from residential to commercial and industrial applications. In addition, this type of refrigeration device 100 has a relatively long service life and relatively low maintenance costs.

[0032] In some alternative embodiments, the cooling device 100 includes a thermoelectric cooler (TEC), the cold end of which contacts the ice box 300. A thermoelectric cooler, also called a semiconductor cooler, is a heat dissipation device made using the Peltier effect (also known as the thermoelectric effect). A P-type semiconductor and an N-type semiconductor are placed in a circuit to form a unit. When energized, electron-hole pairs are generated at one end, reducing internal energy and lowering temperature, forming a cold end; at the other end, electron-hole recombination increases internal energy and raises temperature, forming a hot end. Because this cooling device 100 uses a thermoelectric cooler, it has no moving parts, thus enabling near-silent operation, making it particularly suitable for noise-sensitive environments and providing a more comfortable user experience. Furthermore, the thermoelectric cooler can be made very small and flexible in shape, making it suitable for space-constrained devices such as miniature tabletop ice makers and in-vehicle ice makers.

[0033] In some alternative implementations, such as Figure 4 As shown, the ice-making equipment also includes a filter 800. The filter 800 can be installed in the ice-making pipeline 400, the de-icing pipeline 500, or both. The filter 800 filters the liquid before it enters the spray structure 200, thus delaying or preventing nozzle clogging and extending nozzle lifespan. Furthermore, the filter 800 filters impurities from the liquid, improving its cleanliness and increasing the safety of the ice.

[0034] In some alternative embodiments, the ice-making device also includes a capillary tube disposed between the condenser 130 and the evaporator 110. The capillary tube is used to cool the liquid output from the condenser 130 again before delivering it to the evaporator 110.

[0035] 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.

[0036] Second Embodiment The second embodiment of this application provides an ice-making device, which is an improvement on the ice-making device provided in the first embodiment above. It includes all the features of the ice-making device provided in the first embodiment above, and will not be repeated here.

[0037] In some alternative implementations, such as Figure 5 As shown, the ice-making equipment also includes a hot water supply system, which includes a heater 610, a hot water pipe 620, and a hot water tap 630. The hot water pipe 620 is connected to the hot water tap 630, and the de-icing pipe 500 is connected to the hot water pipe 620. In this type of ice-making equipment, not only ice cubes but also hot water can be provided to users. The heater 610 heats the water in the hot water pipe 620, and hot water is dispensed when the hot water tap 630 is opened. This ice-making equipment can provide both ice cubes and hot water, meeting various user needs. Since the de-icing pipe 500 is connected to the hot water pipe 620, the hot water heated by the heater 610 can enter the de-icing pipe 500 for de-icing via the hot water pipe 620. For example, the heater 610 can be an instantaneous heater 610, which includes a heating pipe and a heating rod. The heating pipe is wound around the heating rod, and the heating rod heats the liquid inside the heating pipe. The diameter of the heating pipe is relatively small, thus achieving high heating efficiency. The heating pipe is connected to the hot water pipe 620, or a portion of the structure of the hot water pipe 620 is wrapped around the heating rod to be used as a heating pipe.

[0038] In some alternative embodiments, the ice-making device includes a water tank 900 and a first pipeline connected to both the water tank 900 and a heater 610, with the ice-making pipeline 400 connected to the water tank 900. In this configuration, the heater 610 heats the water supplied by the first pipeline and delivers it to the de-icing pipeline 500. The water tank 900 supplies liquid to both the ice-making pipeline 400 and the first pipeline; that is, the liquid in the de-icing pipeline 500 and the liquid in the ice-making pipeline 400 both originate from the water tank 900. This ensures that the first and second liquids sprayed by the spray structure 200 are the same liquid at different temperatures, i.e., de-icing is performed using the same liquid as the ice cubes, thereby maintaining the consistency of the ice cube flavor. For example, the liquid in the water tank 900 used for ice making and de-icing can be water or other beverages.

[0039] Third Embodiment The third embodiment of this application provides an ice-making device, which is an improvement on the ice-making device provided in the first embodiment above. It includes all the features of the ice-making device provided in the first embodiment above, and will not be repeated here.

[0040] In the ice-making equipment provided in this embodiment, such as Figure 6 As shown, the refrigeration device 100 includes a heating end, and the ice-making equipment also includes a heat exchange tank 700 for holding liquid. At least a portion of the heating end is located in the heat exchange tank 700 so that the liquid in the heat exchange tank 700 is heated to become a second liquid. The heat exchange tank 700 is connected to the de-icing pipeline 500 and is used to supply the second liquid to the de-icing pipeline 500.

[0041] In one specific embodiment, the refrigeration device 100 includes a compressor 120 and a condenser 130. Exemplarily, during operation, the compressor 120's casing and exhaust port heat up, with the exhaust port generating more heat than the casing. The heating end of the compressor 120 includes the casing and the exhaust port. A portion of the exhaust port's piping can extend into a heat exchange tank 700, allowing the exhaust port piping to exchange heat with the liquid in the heat exchange tank 700, thereby heating the liquid. The condenser 130 includes a heat dissipation pipe 131 and a fan 132. The heat dissipation pipe 131 is a coil or solenoid. The high-temperature, high-pressure gas discharged from the compressor 120 enters the heat dissipation pipe 131, which dissipates heat into the air. The fan 132 blows air onto the heat dissipation pipe 131, thereby accelerating airflow to lower the ambient temperature of the heat dissipation pipe 131 and improve its heat dissipation effect. The heating end of the condenser 130 is the heat dissipation pipe 131, such as... Figure 6 As shown, a portion of the heat dissipation pipe 131 can be inserted into the heat exchange tank 700 to exchange heat with the liquid in the heat exchange tank 700.

[0042] In some alternative embodiments, the refrigeration device 100 includes a semiconductor refrigerator, which includes a cold end for making ice and a hot end. The hot end of the semiconductor refrigerator is the heat-generating end. A portion of the emitting end can be inserted into the heat exchange tank 700, or heat dissipation fins can be added to the heat-generating end and inserted into the heat exchange tank 700. The addition of heat dissipation fins can increase the volume of the part of the structure of the heat-generating end that extends into the heat exchange tank 700, thereby increasing the heat exchange efficiency.

[0043] Fourth embodiment The fourth embodiment of this application provides an ice-making device, which is an improvement on the ice-making device provided in the first embodiment above. It includes all the features of the ice-making device provided in the first embodiment above, and will not be repeated here.

[0044] In the ice-making equipment provided in this embodiment, the refrigeration device 100 includes a heating end, the de-icing pipe 500 is in contact with the heating end, and a portion of the structure of the de-icing pipe 500 is arranged around the outer periphery of the heating end.

[0045] In one specific embodiment, the refrigeration device 100 includes a compressor 120 and a condenser 130. The de-icing conduit 500 can contact either the heating end of the compressor 120 or the heating end of the condenser 130. Exemplarily, during operation, the compressor 120's casing and exhaust port heat up, with the exhaust port generating more heat than the casing. The heating end of the compressor 120 includes both the casing and the exhaust port. The portion of the de-icing conduit 500 in contact with the heating end of the compressor 120 can be made of a smaller diameter conduit, similar in size to the conduit wound around the heating rod in an instantaneous heater 610. Because the conduit diameter is smaller, the wall can be relatively thinner, and the amount of liquid flowing through it is relatively smaller. This allows the heat generated at the heating end to be sufficient to rapidly raise the temperature of the liquid inside the conduit, achieving rapid heating. For example, the de-icing conduit 500 is wound around the outside of the compressor housing 120, and the de-icing conduit 500 may be wound multiple times around the outside of the compressor housing 120 to allow the liquid to flow outside the compressor 120 for a longer period of heat exchange. In another example, the de-icing conduit 500 is wound around the outside of the compressor 120 exhaust port, and the de-icing conduit 500 is wound multiple times around the outside of the compressor 120 exhaust port. In yet another example, the de-icing conduit 500 is partially wound around the outside of the compressor housing 120 and partially wound around the periphery of the compressor 120 exhaust port.

[0046] The condenser 130 includes a heat dissipation pipe 131 and a fan 132. The heat dissipation pipe 131 is a coil or solenoid. The high-temperature, high-pressure gas discharged from the compressor 120 enters the heat dissipation pipe 131, which dissipates heat into the air. The fan 132 blows air onto the heat dissipation pipe 131, thereby accelerating airflow, reducing the ambient temperature of the heat dissipation pipe 131, and improving its heat dissipation effect. The heat-generating end of the condenser 130 is the heat dissipation pipe 131. The de-icing pipe 500 can be spirally wound around the outer circumference of the heat dissipation pipe 131, with a certain gap between adjacent coils of the spiral de-icing pipe 500. When a higher-temperature second liquid needs to be provided to the spray structure 200, the power of the fan 132 can be reduced to decrease the heat dissipation effect of the de-icing pipe 500, thereby improving the temperature rise of the liquid inside the de-icing pipe 500. When it is not necessary to provide a second liquid with a high temperature for the spray structure 200, the power of the fan 132 can be increased. The fan 132 and the heat dissipation pipe 131 work together to dissipate heat from the heat dissipation pipe 131, thereby improving the heat dissipation effect of the heat dissipation pipe 131.

[0047] In some alternative embodiments, the refrigeration device 100 includes a semiconductor refrigerator, which includes a cold end for ice making and a hot end, the hot end of which is the heating end. The de-icing conduit 500 is in contact with the heating end, and a portion of the de-icing conduit 500 is wrapped around the outer periphery of the heating end. In this configuration, the de-icing conduit 500 recovers heat from the heating end of the refrigeration device 100 for de-icing, reducing energy consumption during de-icing.

[0048] In one alternative implementation, the de-icing conduit 500 may be a flat tube to increase the contact area with the heating end.

[0049] 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.
