Description

Technical Field

[0001] This application belongs to the field of refrigeration technology, and in particular relates to a refrigeration device. Background Technology

[0002] In related technologies, most existing ice makers adopt a de-icing solution by directly attaching heating wires above the ice evaporator. However, this de-icing method has many drawbacks: First, the heat conduction efficiency is low. The heating wires can only locally heat the upper part of the ice evaporator, causing the refrigerant in the upper part to vaporize, but the liquid refrigerant in the lower part flows slowly, thus prolonging the de-icing time (usually about 1 hour). Second, in order to ensure food safety, the ice evaporator is usually made of food-grade stainless steel. However, stainless steel has a low thermal conductivity, which further reduces the heating efficiency. This means that the heater needs to reach a high temperature (e.g., 200°C) to achieve de-icing. This not only consumes a lot of energy, but also easily causes the ice to partially melt, affecting the quality of the ice. In addition, high-temperature heating may also accelerate the aging of the equipment and reduce the service life of the ice maker. Summary of the Invention

[0003] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes a refrigeration device that significantly improves de-icing efficiency, comprehensively enhances ice-forming quality, and extends the service life of the ice maker.

Detailed Implementation

[0022] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0023] This application discloses a refrigeration device.

[0024] The refrigeration equipment in this application embodiment can be understood as a broad refrigeration storage device, including but not limited to refrigerators, freezers, display cases, beverage cabinets, wine cabinets, refrigerated display cases, cosmetic storage cabinets, and refrigerated vending machines. The refrigeration equipment has various structural forms, such as vertical, horizontal, small wall-mounted, or vehicle-mounted types.

[0025] The refrigeration equipment includes a cabinet, which may include a cabinet and a door. The cabinet can form a compartment for storage, and the door is installed on the open side of the cabinet to close the compartment.

[0026] The cabinet may include an outer shell, an inner liner, and an insulation layer. The cabinet may be made of plastic, metal, or glass.

[0027] The inner liner may be disposed within the outer shell, and the inner liner may include at least one of a shell, a plate, a panel, or a gasket for forming a compartment. The inner liner may be integrally formed from a single shell, or it may be assembled from multiple plates. Alternatively, at least one of the shell and the plate may form the main structure of the inner liner, and the panel or gasket may be installed on the inner wall of the main structure of the inner liner to form a multi-layered plate structure, or the main structure of the inner liner may have a notch, and the panel or gasket may seal the notch.

[0028] The insulation layer can insulate the interior and exterior of the room, reducing the influence of the external environment on the interior temperature and maintaining it at a set suitable temperature. In some embodiments, the insulation layer may include a foamed insulation layer; in some embodiments, the insulation layer may include a vacuum insulation panel; in some embodiments, the insulation layer may include both a foamed insulation layer and a vacuum insulation panel.

[0029] The foamed insulation layer can be formed between the outer shell and the inner liner through a foaming process. For example, it can be formed by injecting polyurethane foam mixed with polyurethane and foaming agent between the inner liner and the outer shell and allowing it to foam. The vacuum insulation panel can include a core material and an outer skin material that contains the core material and seals the interior to a vacuum or near-vacuum pressure.

[0030] The insulation layer is not limited to the aforementioned foamed insulation layer and vacuum insulation panel layer, but may also include various other materials used for thermal insulation.

[0031] The room can store various items such as food, medicine, and cosmetics. The room can be designed to be open on at least one side to facilitate the access of items.

[0032] A refrigeration unit may contain one or more compartments. When a refrigeration unit comprises two or more compartments, each compartment may serve a different purpose and maintain a different temperature. Therefore, the compartments can be separated from each other by partitions containing insulation.

[0033] The compartments can be configured to maintain different temperature ranges depending on their purpose, and may include refrigerator compartments, freezer compartments, or variable temperature compartments, differentiated by purpose and / or temperature range. Refrigeration compartments maintain temperatures suitable for refrigerated storage, while freezer compartments maintain temperatures suitable for frozen storage. "Refrigeration" can refer to cooling items to a low temperature that prevents freezing, for example, a refrigerator compartment can maintain a temperature between 0°C and 10°C, or between 0°C and 5°C. "Freezing" can refer to cooling items to a frozen state or maintaining a frozen state, for example, a freezer compartment can maintain a temperature between -20°C and -1°C, or between -40°C and -1°C (e.g., a dual-compressor system / dual-refrigerant design can achieve even lower cooling temperatures), or between -60°C and -1°C (e.g., a dual-compressor system / dual-refrigerant design can achieve even lower cooling temperatures). Variable temperature compartments can be selected by the user or automatically switched to be used as refrigerator or freezer compartments.

[0034] Of course, the different compartments of the room may have other names, including but not limited to vegetable room, fresh food room, cooling room, ice making room, etc., which are essentially different zones of cold storage room, freezer room or variable temperature room. The terms cold storage room, freezer room, variable temperature room, etc. used below should be understood to cover all rooms with corresponding uses and temperature ranges.

[0035] In some embodiments, the refrigeration unit may include at least one door for opening and closing the open side of a compartment. A door may be configured to open and close one or more compartments. The door may be rotatably or slidably mounted on the front of the cabinet. The door may be hinged to the cabinet, or the door may be integrated with a drawer.

[0036] The door can be configured to seal the compartment when closed, and the door can also include an insulation layer to insulate the compartment when the door is closed.

[0037] In some embodiments, the door may include an outer door panel forming the front of the door, an inner door liner forming the back of the door and facing the compartment, and a door insulation layer disposed between the outer door panel and the inner door liner.

[0038] The inner edge of the door lining may be fitted with a door seal that fits snugly against the cabinet when the door is closed, thus sealing the compartment. The inner door panel may include a door shelf that protrudes into the compartment for storing items such as beverages, medicines, or other items.

[0039] In some embodiments, the outer door panel may also be provided with a display screen, an exterior panel, etc.

[0040] In some embodiments, the refrigeration equipment does not have high insulation requirements, such as display cases and beverage cabinets. The door of the refrigeration equipment may include a transparent panel, such as a glass panel or an acrylic panel. Of course, the door may also be designed as a multi-layered transparent panel, and in some embodiments, a vacuum may be drawn between the multi-layered transparent panels to improve insulation performance.

[0041] Refrigeration equipment can be classified into French door type, double door type, bottom-mounted freezer type, top-mounted freezer type, or single-door refrigeration equipment according to the layout of the doors and compartments.

[0042] In some embodiments, the refrigeration equipment may include a refrigeration system for supplying cold air to a room.

[0043] In some embodiments, the refrigeration system may include a compressor, a condenser, a throttling device, and an evaporator. The refrigeration system may also include a semiconductor refrigerator, such as a thermoelectric element, which can utilize the Peltier effect to heat and cool the compartment.

[0044] In some embodiments, the cabinet may form a compressor compartment, in which the compressor and condenser may be located, and the compressor compartment and the compartment may be separated and insulated from each other.

[0045] The following is for reference. Figures 1-12 This application describes a refrigeration device according to an embodiment of the present application.

[0046] In some embodiments, the refrigeration equipment includes: a housing, an ice-making refrigeration system 800, and an ice maker 10.

[0047] The box forms a compartment, and the structural form of the box can be referred to the description of the above embodiment.

[0048] The ice maker 10 is installed in the compartment, and the ice maker 10 can be installed in the cold storage compartment.

[0049] like Figures 1-5 As shown, the ice maker 10 includes: a housing 100, an ice evaporator 200, an ice container 300, an ice storage container 400, and a water tank 500.

[0050] The ice evaporator 200 is installed on the housing 100, and the installation method includes but is not limited to welding, snap-fit ​​and threaded connection; the ice container 300 is used to hold the liquid to be made into ice. The ice container 300 is installed on the housing 100 in a flip-up manner. Flip-up means that the ice container 300 can rotate around the flip axis at a certain angle. The maximum rotation range can be 85°-360°.

[0051] The ice-making section of the ice-making evaporator 200 is adapted to extend into the ice-making container 300. When the ice-making evaporator 200 is cooled to a suitable temperature, the liquid to be made into ice in the ice-making container 300 can freeze and adhere to the ice-making section of the ice-making evaporator 200.

[0052] The ice storage container 400 is located below the ice evaporator 200, which can be directly below or diagonally below; the ice storage container 400 forms an ice storage cavity 401 that is suitable for being arranged opposite to the ice making part, and the ice in the ice evaporator 200 can fall into the ice storage cavity 401.

[0053] The ice storage container 400 is removably installed on the housing 100. The housing 100 is provided with an ice dispensing port 103 for taking out and putting in the ice storage container 400. When the ice storage container 400 is pulled out at least partially from the ice dispensing port 103, it is convenient to take out ice.

[0054] Water tank 500 is installed on housing 100, and water circulation is formed between water tank 500 and ice container 300. Water tank 500 is located below ice storage container 400, so that water (melting water or other water) in ice storage container 400 can flow into water tank 500.

[0055] The ice maker 10 can be installed as an independent ice-making module capable of generating and storing ice within the refrigeration equipment compartment.

[0056] For example, the ice maker 10 of this application is installed inside the refrigerator compartment of a refrigeration system. For instance, the ice maker 10 can be installed on the inner liner of the refrigerator compartment. Alternatively, the ice maker 10 can be installed on the door.

[0057] Among them, such as Figures 1-5 As shown, the housing 100 serves as the supporting structure and external enclosure frame of the ice maker 10. The interior of the housing 100 can form an installation space for accommodating the ice evaporator 200, ice container 300, ice storage container 400, water tank 500, electrical components, and water circuit components, so that the ice maker 10 can be assembled and maintained as a complete module.

[0058] The ice storage container 400 can be pulled out and installed on the housing 100 along the front and rear direction of the refrigeration equipment via a guide rail structure. The ice storage container 400 can define an ice storage cavity 401, which is used to receive ice blocks that fall off from the ice-making part of the ice-making evaporator 200.

[0059] like Figures 2-5As shown, the bottom of the ice storage container 400 is lower than the ice-making evaporator 200 in the height direction, so that at least a portion of the ice-making part of the ice-making evaporator 200 can be immersed in the liquid in the ice storage container 400. The ice storage container 400 can be located directly below the ice-making evaporator 200, or it can be at least partially offset from the ice-making evaporator 200. The specific relative positional relationship should not affect the normal ice storage function, and this embodiment does not limit this.

[0060] A water circulation system is formed between the water tank 500 and the ice-making container 300. The water tank 500 is used to store water for ice making and can also be used to collect water from melting ice. The water tank 500 can be pulled out and installed on the casing 100 along the front and rear direction of the refrigeration equipment via a guide rail structure.

[0061] Of course, the water tank 500 can also be used only to receive the overflow water from the ice container 300 and the water from melting ice. The ice container 300 can be equipped with a separate water supply mechanism.

[0062] like Figures 2-5 As shown, the water tank 500 is lower than the ice storage container 400 in the height direction. The water tank 500 can be located directly below the ice storage container 400, or it can be at least partially offset from the ice storage container 400. The specific relative position relationship is based on not affecting the normal discharge of ice melt water and the water circulation function. This application embodiment does not limit this.

[0063] As an example, the ice maker 10 may also include structures such as electrical components and water circuit components. The water tank 500 can supply water to the ice container 300 through the water circuit components. The ice container 300 can be flipped under the drive of the electrical components, so that the water in the ice container 300 that has not frozen into ice blocks flows back to the water tank 500.

[0064] At least a portion of the ice-making section of the ice-making evaporator 200 extends into the ice-making container 300 and comes into direct contact with the liquid (such as water) inside the ice-making container 300, causing the water surrounding the ice-making section to freeze after being cooled, so as to form an ice block that is fitted outside the ice-making section. Since the ice-making section is located in the central area of ​​the ice block structure, the produced ice block is a hollow structure with a central groove.

[0065] The specific shape of the ice block may include, but is not limited to, hollow cylinder, hollow cube, hollow prism, hollow sphere, or hollow hemisphere, etc., and the embodiments of this application do not limit this.

[0066] like Figures 2-5As shown, the ice evaporator 200 may include a distribution member 210 and a plurality of ice-making columns 220. The ice-making columns 220 may be welded to the distribution member 210. The ice-making part of the ice evaporator 200 includes the ice-making columns 220. The ice-making columns 220 and the ice storage cavity 401 of the ice storage container 400 are arranged vertically opposite each other. The ice storage container 300, which is flipped, can selectively separate the ice storage cavity 401 and the plurality of ice-making columns 220. The ice storage container 300 can be flipped to not separate the ice storage cavity 401 and the plurality of ice-making columns 220, so that when the ice on the ice-making columns 220 falls off, it can fall into the ice storage cavity 401.

[0067] Both the distributor 210 and the ice-making column 220 have interconnected channels for the medium to pass through. The distributor 210 is connected to the ice-making and refrigeration system 800, so that the medium of the ice-making and refrigeration system 800 can flow through the channels of the distributor 210 and the ice-making column 220.

[0068] like Figures 2-5 As shown, in the ice-making state, at least a portion of the multiple ice-making columns 220 extend into the ice-making container 300 to generate ice; in the de-icing state, the ice-making container 300 is flipped to be offset from the multiple ice-making columns 220, that is, flipped to the side of the multiple ice-making columns 220, so that there is no longer an ice-making container 300 between the ice storage cavity 401 and the multiple ice-making columns 220, so that the ice generated on the ice-making columns 220 falls into the ice storage cavity 401.

[0069] The distribution component 210 is used to distribute the refrigerant of the future homemade ice refrigeration system 800 to multiple ice-making columns 220. The distribution component 210 can be, but is not limited to, a distribution plate or a distribution pipe, etc. The embodiments of this application do not limit this.

[0070] like Figures 2-5 As shown, the ice-making column 220 can be designed as a cylinder, and multiple ice-making columns 220 can form multiple ice blocks, so that the ice blocks formed on the multiple ice-making columns 220 are hollow cylinders. Here, "multiple ice-making columns 220" means two or more.

[0071] The ice-making function can be achieved in the following ways: Figures 2-5As shown, when the ice maker 10 is in the ice-making state, the opening of the ice container 300 faces upward, and a portion of each ice column 220 of the ice evaporator 200 can be immersed below the liquid surface in the ice container 300. The refrigerant flowing through the ice evaporator 200 evaporates and absorbs heat, causing the surface temperature of the ice evaporator 200 to drop sharply, which in turn causes the water around the ice column 220 to freeze quickly and eventually condense and adhere to each ice column 220 to form ice blocks. In some embodiments, during ice making, the water tank 500 continuously supplies water to the ice-making container 300 through the water circuit assembly. When the water level rises above the maximum capacity of the ice-making container 300, the remaining water overflows from the ice-making container 300 and falls back into the water tank 500 under gravity. In other words, throughout the ice-making process, the water tank 500 continuously supplies water to the ice-making container 300, without stopping even when the ice-making container 300 reaches its maximum water level. This ensures that the water in the ice-making container 300 remains in circulation, which reduces the formation of air bubbles in the ice. Of course, the water circuit assembly can also stop supplying water to the ice-making container 300 during ice making.

[0072] The de-icing function is achieved as follows: electrical components drive the ice-making container 300 to rotate. During rotation, the controller of the refrigeration equipment controls the rotational speed of the tilting shaft of the ice-making container 300 to maintain smooth rotation as much as possible. By driving the ice-making container 300 to tilt, the unfrozen water inside the ice-making container 300 is returned to the water tank 500. When the ice maker 10 is in the de-icing state, the opening of the ice-making container 300 faces to the side, and the ice-making container 300 does not obstruct the space below the ice-making column 220. The ice layer adhering between the ice cube and the corresponding ice-making column 220 melts into a water film when heated, greatly reducing the adhesion. Thus, the ice cube originally attached to the ice-making column 220 can be peeled off by its own gravity and fall into the ice storage chamber 401 of the ice storage container 400 below. The user can open the chamber at any time to take out the ice cube in the ice storage chamber 401.

[0073] like Figures 9-11 As shown, the ice-making refrigeration system 800 includes a compressor 810, a condenser 820, a first throttling section 830, a refrigeration evaporator 840, and a flow branch 850. The inlet of the ice-making evaporator 200 is connected to the ice-making refrigeration system 800 through the first throttling section 830 or the flow branch 850, and the outlet of the ice-making evaporator 200 is connected in series with the inlet of the refrigeration evaporator 840.

[0074] The refrigeration equipment also includes a controller, which is electrically connected to a fan 841 located in the air duct of the refrigeration evaporator 840; such as Figures 9-12As shown, the controller is configured to: control the first throttling section 830 to be turned on when the refrigeration equipment starts making ice; control the fan 841 to operate at a first speed when the temperature of the cold storage compartment is greater than the preset value; and control the fan 841 to operate at a second speed or run for a target duration at intervals of a target period when the temperature of the cold storage compartment is not greater than the preset value, wherein the first speed is greater than the second speed.

[0075] The fan 841 in the air duct where the refrigerated evaporator 840 is located is used to drive the air flow in the air duct where the refrigerated evaporator 840 is located, thereby supplying air to the refrigerated compartment.

[0076] In actual implementation, such as Figures 9-11 As shown, when the ice maker 10 is in ice-making mode, the overcurrent branch 850 is disconnected, the first throttling section 830 is open, and the inlet of the ice-making evaporator 200 is connected to the ice-making refrigeration system 800 through the first throttling section 830. The high-temperature and high-pressure refrigerant discharged from the compressor 810 is condensed by the condenser 820 and becomes a medium-temperature and high-pressure liquid refrigerant. When the liquid refrigerant flows through the first throttling section 830, it undergoes throttling and pressure reduction, becoming a low-temperature and low-pressure gas-liquid mixture refrigerant. This low-temperature and low-pressure refrigerant enters the ice-making evaporator 200 and exchanges heat with the water in the ice-making container, absorbing heat from the water to freeze the water, thus completing the ice-making process.

[0077] During the ice-making process, the controller can monitor the temperature of the cold storage compartment. For example, the controller monitors the temperature of the cold storage compartment through temperature sensors located inside the cold storage compartment or in the air duct where the cold storage evaporator 840 is located.

[0078] like Figures 9-11 As shown, since the refrigeration evaporator 840 is connected in series downstream of the ice-making evaporator 200, the refrigerant (still in a low temperature and low pressure state) flowing through the ice-making evaporator 200 will continue to flow into the refrigeration evaporator 840.

[0079] like Figure 12 As shown, when the temperature of the cold storage compartment exceeds the preset value, it indicates that the cold storage compartment needs to be cooled and there is a clear cooling requirement. At this time, the controller can control the fan 841 to operate at the first speed. The first speed is the normal cooling speed, which enables the air flowing through the cold storage evaporator 840 to exchange heat efficiently with the low-temperature refrigerant, thereby effectively reducing the temperature of the cold storage compartment and meeting its cooling requirements.

[0080] like Figure 12As shown, when the temperature in the cold storage compartment is not greater than the preset value, it indicates that the temperature in the cold storage compartment has reached or fallen below the set temperature, and additional cooling is not required temporarily. At this time, the controller can control the fan 841 to operate at a second speed, or control the fan 841 to run at a target interval for a target duration (i.e., intermittent operation, for example, running for 1 minute every 2 minutes). The first speed is greater than the second speed. The second speed can be an extremely low speed to maintain micro-air circulation. This reduces wasted cooling capacity, lowers energy consumption, and reduces the risk of excessively low temperatures in the cold storage compartment, protecting the items stored there.

[0081] like Figures 9-11 As shown, when the ice maker 10 is in the de-icing state, the flow branch 850 is open, the first throttling section 830 is closed, and the inlet of the ice evaporator 200 is connected to the ice-making refrigeration system 800 through the flow branch 850. The flow branch 850 acts as a bypass pipe, and its flow resistance is much smaller than that of the first throttling section 830. When hot refrigerant enters the flow branch 850, because it bypasses the first throttling section 830, the refrigerant does not experience a throttling and cooling effect, but instead enters the ice evaporator 200 directly at a higher temperature, thus achieving de-icing.

[0082] The refrigeration equipment provided in this application embodiment, through the aforementioned overflow branch 850, achieves several advantages. Firstly, by bypassing the first throttling section 830, the overflow branch 850 allows a large amount of unthrottled hot refrigerant to flow into the ice-making evaporator 200, achieving efficient ice removal, significantly shortening the ice removal time, and significantly improving ice removal efficiency. Simultaneously, it significantly improves the situation where ice blocks partially melt due to prolonged localized heating, thereby comprehensively improving the quality of ice formation. Furthermore, it reduces the aging effects and safety hazards caused by localized extremely high temperatures resulting from the use of heating elements, extending the service life of the ice maker 10. Secondly, combined with the dynamic control design of the fan 841 during ice making, it effectively balances refrigeration and cooling during ice making, achieving coordinated operation of ice making and refrigeration. This avoids ineffective energy consumption caused by cold energy, effectively alleviating the overcooling problem in the refrigeration compartment caused by passive cooling in the series structure, thereby minimizing temperature fluctuations in the refrigeration compartment during ice making and optimizing the quality of stored goods in the refrigeration compartment.

[0083] In some embodiments, such as Figures 9-12 As shown, the controller is configured to: when the refrigeration equipment starts de-icing, control the overcurrent branch to be turned on, and control the fan 841 to operate at a third speed, which is greater than the first speed.

[0084] It is understandable that during the de-icing process, the refrigerant may return to the compressor 810 in a state containing a large amount of liquid, where it will violently vaporize in the suction chamber of the compressor 810, thereby causing liquid slugging in the compressor 810, damaging the compressor 810 components, and shortening the service life of the compressor 810.

[0085] Based on this, such as Figure 12 As shown, during the de-icing process, this application controls the fan 841 to operate at a third speed, which is much higher than the first speed. This accelerates the airflow around the refrigeration evaporator 840, forces ultra-high velocity airflow through the refrigeration evaporator 840, significantly improves the heat exchange efficiency of the refrigeration evaporator 840, and allows the refrigerant flowing through the refrigeration evaporator 840 to evaporate as completely as possible into a gaseous state. This minimizes the amount of liquid refrigerant entering the compressor 810, thereby effectively reducing the risk of liquid slugging in the compressor 810 and ensuring the stable and reliable operation of the refrigeration equipment.

[0086] It should be noted that the specific value of the third rotation speed can be dynamically adjusted according to parameters such as the exhaust temperature of the compressor 810, the outlet pressure of the condenser 820, and the outlet superheat of the refrigerated evaporator 840. This application embodiment does not limit this.

[0087] For example, when the compressor 810 discharge temperature is high, it indicates that the overall temperature of the refrigerant in the system is high, and the third speed can be appropriately reduced; conversely, if the ambient temperature is low and the condensing pressure is low, a higher third speed is required to forcibly supplement the heat.

[0088] The refrigeration equipment provided in this application embodiment controls the fan 841 to operate at a third speed higher than the first speed during the de-icing period, which greatly improves the heat exchange efficiency of the refrigeration evaporator 840. This helps the refrigerant to completely evaporate into a gaseous state in the refrigeration evaporator 840, reduces the amount of liquid refrigerant entering the compressor 810, significantly reduces the risk of liquid slugging in the compressor 810, effectively protects the components of the compressor 810, extends the service life of the compressor 810, and thus improves the stability and reliability of the refrigeration equipment operation.

[0089] In some embodiments, such as Figures 9-11 As shown, the ice-making and refrigeration system 800 also includes a second throttling section 860 and a freezer evaporator 870.

[0090] The inlet of the refrigeration evaporator 870 is connected to the outlet of the refrigeration evaporator 840 and the outlet of the second throttling section 860. The second throttling section 860 is connected in parallel to the series path formed by the first throttling section 830, the ice-making evaporator 200 and the refrigeration evaporator 840.

[0091] In actual implementation, such as Figures 9-11As shown, the ice-making refrigeration system 800 can operate only for the refrigeration of the freezer compartment. In this case, the refrigerant flow path can be: compressor 810 - condenser 820 - second throttling section 860 - refrigeration evaporator 870 - compressor 810. Under this condition, no refrigerant flows through the ice-making evaporator 200 and the refrigeration evaporator 840, and there is no ineffective heat exchange.

[0092] The ice-making and refrigeration system 800 can also operate simultaneously for ice making, refrigeration of the cold storage compartment, and refrigeration of the freezer compartment. In this case, the refrigerant is divided into two paths at the outlet of the condenser 820: one path is throttled by the first throttling section 830, and then passes through the ice-making evaporator 200 and the cold storage evaporator 840 in sequence, reaching the confluence point; the other path is throttled by the second throttling section 860 and directly reaches the confluence point. The two refrigerant streams mix at the confluence point and then enter the freezer evaporator 870.

[0093] The refrigeration equipment provided in this application embodiment, through the above-mentioned second throttling section 860 and refrigeration evaporator 870, allows the refrigerant to flow through the second throttling section 860 and refrigeration evaporator 870 separately, efficiently meeting the low temperature requirements of the freezer compartment. It can also distribute the refrigerant flow proportionally to achieve parallel freezing, refrigeration and ice making, thereby improving the system energy efficiency.

[0094] In some embodiments, such as Figure 9 As shown, the ice-making and refrigeration system 800 also includes a heating element 890.

[0095] The heating element 890 is used to transfer heat to the refrigerant in the pipe between the inlet of the flow branch 850 and the inlet of the ice evaporator 200.

[0096] The heating element 890 can be a common heating element such as an electric heating wire, a PTC heater, a thin film heater, or an induction heater. Its power and heating temperature can be adjusted according to actual needs, and this application embodiment does not limit this.

[0097] The heating element 890 can be installed in close contact with the pipe between the inlet of the flow branch 850 and the inlet of the ice evaporator 200 by means of binding, clamping, or embedding; or the heating element 890 can also conduct heat through an intermediate structure (mounting bracket, thermal conductive adhesive, etc.) by indirect installation; or the heating element 890 can also achieve non-contact heat conduction by energy radiation, which is not limited in this embodiment.

[0098] Understandably, in low ambient temperatures, the heat output of the ice-making refrigeration system 800 may be insufficient, leading to difficulties in de-icing. Specifically, during the de-icing stage, the hot refrigerant from the compressor 810 alone may not be enough for rapid de-icing in low-temperature environments. By adding a heating element 890, which can directly assist in heating the refrigerant in the pipes, the temperature of the refrigerant entering the ice-making evaporator 200 is increased, accelerating the formation of a water film at the ice interface and shortening the de-icing time.

[0099] The refrigeration equipment provided in this application embodiment, through the setting of the heating element 890, uses the heating element 890 as a supplementary heat source to further heat the refrigerant, so that the temperature of the refrigerant entering the ice-making evaporator 200 is higher, further improving the de-icing efficiency and further shortening the de-icing time. At the same time, it enables the refrigeration equipment to maintain effective de-icing in any environment, reducing ice residue, thereby enhancing the reliability of de-icing and environmental adaptability.

[0100] The embodiments of this application will be described in detail below from two different implementation perspectives.

[0101] I. In some embodiments, such as Figure 9 As shown, the heating element 890 is located in the overcurrent branch 850.

[0102] In this embodiment, such as Figure 9 As shown, the heating element 890 is connected in parallel to the first throttling section 830 through the flow branch 850. During ice making, the refrigerant from the condenser 820 enters the first throttling section 830, and the refrigerant from the first throttling section 830 directly enters the ice-making evaporator 200 without passing through the heating element 890.

[0103] By placing the heating element 890 in the overcurrent branch 850, the ice-making state and the ice-removing state are completely isolated, reducing the energy loss of refrigerant in the heating element 890 during the ice-making state. At the same time, during the ice-making state, the heating element 890 is completely dormant and is not subjected to low temperature, vibration and refrigerant erosion, reducing the number of thermal cycles and the time of harsh working conditions of the heating element 890, effectively slowing down material aging and performance degradation, thereby improving the long-term reliability of the ice maker 10.

[0104] II. In some embodiments, such as Figure 10 As shown, the heating element 890 is located between the flow branch 850 and the ice evaporator 200.

[0105] In this embodiment, such as Figure 10As shown, the first throttling section 830, the heating element 890, and the ice-making evaporator 200 are arranged in series. During ice making, the refrigerant from the condenser 820 enters the first throttling section 830, and the refrigerant from the first throttling section 830 needs to flow through the heating element 890 before entering the ice-making evaporator 200. However, the heating element 890 is in a non-operating state during the ice-making process.

[0106] By placing the heating element 890 between the outlet of the first throttling section 830 and the inlet of the ice-making evaporator 200, the heating element 890 serves as a common series component of the flow branch 850 and the first throttling section 830, reducing the number of pipe welding points, pipe material usage, and related fasteners, thereby simplifying the assembly process and reducing the material and manufacturing costs of the system.

[0107] In some embodiments, such as Figure 9 As shown, the ice-making and refrigeration system 800 also includes a pressure-holding valve 804.

[0108] Pressure holding valve 804 is located at the inlet of compressor 810.

[0109] In actual implementation, such as Figure 9 As shown, considering that the high-temperature, high-pressure refrigerant, without throttling during the de-icing stage, will flow directly to the compressor 810 through the return gas line, causing the compressor 810 to be subjected to huge high-pressure and liquid shocks, a pressure-holding valve 804 is connected in series on the suction line of the compressor 810. The pressure-holding valve 804 can be used to regulate, maintain, or limit the refrigerant pressure entering the compressor 810. Specifically, the pressure-holding valve 804 can actively limit the refrigerant pressure and flow rate entering the compressor 810, ensuring that it always operates within a safe design range, thereby effectively reducing motor overload caused by high-pressure shocks and compressor 810 damage or malfunction caused by liquid slugging.

[0110] The refrigeration equipment provided in this application embodiment, through the setting of the pressure holding valve 804, can maintain the stability of the inlet pressure of the compressor 810, reduce the liquid slugging and high pressure impact of the unthrottled refrigerant on the compressor 810 during the de-icing stage, so that the actual working load of the compressor 810 during the de-icing stage will not exceed its safe range, thus achieving effective protection of the compressor 810, reducing the failure rate of the compressor 810, thereby extending the life of the compressor 810, and improving the reliability of the whole machine.

[0111] In some embodiments, such as Figure 9 As shown, the ice-making and refrigeration system 800 also includes: a first control valve 801.

[0112] The four valve ports of the first control valve 801 are respectively connected to the outlet of the condenser 820, the inlet of the overflow branch 850, the inlet of the first throttling section 830, and the inlet of the second throttling section 860.

[0113] In other words, the first control valve 801 controls the on / off connection between the condenser 820 and the flow branch 850, the first throttling section 830, and the second throttling section 860. Thus, the switching between ice-making, compartment cooling, de-icing, and defrosting modes can be achieved by the operation of a single first control valve 801.

[0114] It should be noted that, as Figure 9 As shown, a filter device 880 is provided between the inlet of the first control valve 801 and the outlet of the condenser 820. The filter device 880 can filter the refrigerant upstream of the first control valve 801, intercepting contaminants in the refrigerant, thereby significantly reducing the risk of blockage of the first control valve 801.

[0115] In this case, such as Figure 9 As shown, in ice-making mode, the refrigerant flow path is: compressor 810 - condenser 820 - filter device 880 - first control valve 801 - first throttling section 830 - ice-making evaporator 200 - refrigeration evaporator 840 - freezing evaporator 870 - compressor 810.

[0116] In the de-icing state, such as Figure 9 As shown, the refrigerant flow path is: compressor 810 - condenser 820 - filter device 880 - first control valve 801 - flow branch 850 - ice evaporator 200 - refrigerator evaporator 840 - freezer evaporator 870 - compressor 810.

[0117] The refrigeration equipment provided in this application embodiment, through the aforementioned second throttling section 860, refrigerated evaporator 870, and first control valve 801, enables a single valve to control the switching of compartment refrigeration, ice making, ice removal, and defrosting functions. This greatly simplifies the piping system, reduces the number of welding points and connectors in the piping, and makes the system layout more compact and neat. It not only improves the internal space utilization of the refrigeration equipment but also reduces the risk of refrigerant leakage due to excessive welding points. This achieves a high degree of system integration and structural simplification. At the same time, during production and assembly, relevant operators only need to assemble one valve body and its related interfaces, rather than multiple scattered valves and pipes, thereby significantly simplifying the assembly process and shortening the assembly time.

[0118] In some embodiments, such as Figure 10 and Figure 11 As shown, the ice-making and refrigeration system 800 also includes a second control valve 802 and a third control valve 803.

[0119] The second control valve 802 is used to control the opening and closing of the overflow branch 850; the three valve ports of the third control valve 803 are respectively connected to the outlet of the condenser 820 of the ice-making and refrigeration system 800, the inlet of the first throttling section 830 and the inlet of the second throttling section 860.

[0120] In other words, the third control valve 803 controls the on / off connection between the condenser 820 and the first throttling section 830 and the second throttling section 860. Thus, the operation of the second control valve 802 can switch between de-icing modes, while the operation of the third control valve 803 can switch between ice-making and compartment cooling modes.

[0121] As an example, such as Figure 10 As shown, the second control valve 802 can be installed on the overflow branch 850.

[0122] As an example, such as Figure 11 As shown, the second control valve 802 can also be installed at the inlet of the overflow branch 850.

[0123] It should be noted that, as Figure 10 and Figure 11 As shown, a filter device 880 is provided between the inlet of the third control valve 803 and the outlet of the condenser 820. The filter device 880 can filter the refrigerant upstream of the third control valve 803, intercepting contaminants in the refrigerant, thereby significantly reducing the risk of blockage of the third control valve 803.

[0124] The refrigeration equipment provided in this application embodiment, through the configuration of the second control valve 802, the second throttling section 860, the refrigeration evaporator 870, and the third control valve 803, achieves the switching of the de-icing function controlled by the second control valve 802, and the switching of the compartment refrigeration and ice-making functions controlled by the third control valve 803. This reduces the complexity of system debugging and maintenance, thereby achieving functional modularity and control specificity. Furthermore, if one of the second control valve 802 and the third control valve 803 fails, it will not affect the operation of the corresponding function of the other, thus achieving fault isolation and improving the fault tolerance and reliability of the entire refrigeration equipment.

[0125] In some embodiments, such as Figure 10 As shown, the inlet of the overcurrent branch 850 is connected to the outlet of the compressor 810.

[0126] In other words, such as Figure 10 As shown, the overflow branch 850 is connected in parallel with the series path consisting of the condenser 820, the filter device 880 and the first throttling section 830.

[0127] In this case, such as Figure 10As shown, in ice-making mode, the refrigerant flow path is: compressor 810 - condenser 820 - filter device 880 - third control valve 803 - first throttling section 830 - ice-making evaporator 200 - refrigerator evaporator 840 - freezer evaporator 870 - compressor 810.

[0128] In the de-icing state, such as Figure 10 As shown, the refrigerant flow path is: compressor 810 - flow branch 850 (second control valve 802) - ice evaporator 200 - refrigeration evaporator 840 - freezing evaporator 870 - compressor 810.

[0129] The refrigeration equipment provided in this application embodiment has a structural design in which the ice-making evaporator 200 can be selectively connected to the outlet of the compressor 810 through the second control valve 802 and the overflow branch 850. This allows the high-temperature refrigerant leaving the compressor 810 to be directly sent into the ice-making evaporator 200 through the overflow branch 850, thereby maximizing the de-icing temperature, improving the de-icing efficiency as much as possible, and shortening the de-icing cycle.

[0130] In some embodiments, such as Figure 11 As shown, the inlet of the overflow branch 850 is connected to the outlet of the condenser 820.

[0131] In other words, such as Figure 11 As shown, the series path consisting of the overflow branch 850, the filter device 880, and the first throttling section 830 is connected in parallel.

[0132] In this case, such as Figure 11 As shown, in ice-making mode, the refrigerant flow path is: compressor 810 - condenser 820 - filter device 880 - third control valve 803 - first throttling section 830 - ice-making evaporator 200 - refrigerator evaporator 840 - freezer evaporator 870 - compressor 810.

[0133] In the de-icing state, such as Figure 11 As shown, the refrigerant flow path is: compressor 810 - condenser 820 - second control valve 802 - flow branch 850 - ice evaporator 200 - refrigerator evaporator 840 - freezer evaporator 870 - compressor 810.

[0134] Understandably, because the flow direction of the compressor 810 outlet frequently and abruptly switches from the condenser 820 to the overflow branch 850, a large amount of refrigerant accumulates in the condenser 820 and its upstream pipeline. Due to the lack of driving force, this refrigerant remains on the condenser 820 side, resulting in insufficient refrigerant flow actually participating in the de-icing cycle in a short period of time, and slow pressure build-up, thus affecting the start-up speed and initial effect of de-icing.

[0135] The refrigeration equipment provided in this application embodiment, through the structural design of the ice-making evaporator 200 selectively connected to the outlet of the condenser 820 via the second control valve 802 and the overflow branch 850, allows the condenser 820 to incorporate de-icing and defrosting cycles. This enables the refrigerant accumulated in the condenser 820 to be pushed out, ensuring sufficient heat transfer during de-icing and defrosting. This shortens the time required for the compressor 810 to establish a pressure difference, accelerates the start-up speed of de-icing and defrosting, and thus comprehensively optimizes the de-icing and defrosting effects.

[0136] In some embodiments, such as Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown, the bottom wall of the ice storage cavity 401 is inclined downward from at least one end near the ice outlet 103 to the other end away from the ice outlet 103, and a drain outlet 402 is provided in the area of ​​the bottom wall of the ice storage cavity 401 away from the ice outlet 103.

[0137] In other words, with the ice outlet 103 facing the front of the refrigeration equipment, the bottom wall of the ice storage chamber 401 is at least partially inclined downward from the front end to the rear end.

[0138] In this embodiment, such as Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown, a portion of the bottom wall of the ice storage cavity 401 is inclined downwards from one end near the ice outlet 103 to the other end away from the ice outlet 103, that is, a portion of the bottom wall of the ice storage cavity 401 is inclined downwards from the front end to the rear end. The end near the ice outlet 103 can be the front side of the refrigeration equipment, that is, the side facing the door.

[0139] In other embodiments, the bottom wall of the ice storage cavity 401 is inclined downward from one end near the ice outlet 103 to the other end away from the ice outlet 103, that is, the bottom wall of the ice storage cavity 401 is inclined downward from the front end to the rear end.

[0140] The tilt angle can be adapted to the actual drainage situation and ice storage capacity requirements, and the embodiments of this application do not limit this.

[0141] In actual operation, during the ice removal process, the bottom wall of the ice storage cavity 401 can effectively guide the melting water of the ice to flow quickly to the drain 402 located at the rear by using its own tilting trend, thereby reducing the long-term retention of the melting water of the ice in the ice storage cavity 401, so as to avoid further aggravating the melting phenomenon of the ice and reducing the occurrence of ice sticking.

[0142] The refrigeration equipment provided in this application embodiment, by setting the bottom wall of the ice storage cavity 401 to be inclined downward from at least part of one end near the ice outlet 103 to the other end away from the ice outlet 103, combined with the design of the drain outlet 402, can use gravity to guide the melted ice water to flow quickly to the drain outlet 402, shortening the residence time of the melted ice water in the ice storage cavity 401, reducing the situation where the ice melts faster due to long-term immersion in the melted water, and reducing the adhesion of ice blocks, thereby optimizing the quality of the ice blocks.

[0143] In some embodiments, such as Figure 6 and Figure 7 As shown, the bottom wall of the ice storage chamber 401 includes a first section 451 and a second section 452. The first section 451 is located on the side of the second section 452 that is close to the ice outlet 103. The second section 452 is inclined downward from one end close to the ice outlet 103 to the other end away from the ice outlet 103. The drain outlet 402 is located in the area of ​​the second section 452 away from the ice outlet 103.

[0144] In this embodiment, such as Figure 6 and Figure 7 As shown, the bottom wall of the ice storage chamber 401 can be formed by a first section 451 and a second section 452 that are bent and connected. With the ice outlet 103 facing the front of the refrigeration equipment, the first section 451 is located in front of the second section 452. The first section 451 is set horizontally, and the second section 452 is set downward from front to back. The drain outlet 402 is set in the rear area of ​​the second section 452. The lengths of the first section 451 and the second section 452 can be adaptively designed according to the actual drainage situation and ice storage capacity requirements.

[0145] Understandably, with Figure 6 and Figure 7 For example, if the existing tilt angle of the second segment 452 remains unchanged, the first segment 451 continues to tilt and extend along the tilt trend of the second segment 452 at the same tilt angle, so that the bottom wall of the ice storage cavity 401 is tilted as a whole. In this case, compared with the ice storage capacity above the horizontally set first segment 451 in this application, the ice storage capacity above the first segment 451 is significantly reduced.

[0146] Based on this, the first section 451 on the front side is set to be horizontal, while the second section 452 on the rear side is set to be inclined. This preserves sufficient ice storage space at the front and ensures a sufficient tilt angle to facilitate rapid drainage of melting ice water. Compared to the overall inclined structure, this maximizes the preservation of effective ice storage space at the front of the ice storage container 400 without affecting the drainage effect at the rear, thus achieving structural optimization.

[0147] The refrigeration equipment provided in this application embodiment, by setting the bottom wall of the ice storage cavity 401 to be composed of a horizontal first section 451 and an inclined second section 452, not only ensures that the bottom wall of the ice storage cavity 401 has a sufficient slope to effectively guide the melting water of the ice to the drain outlet 402, but also avoids excessive encroachment on the front area of ​​the ice storage cavity 401 due to the overall inclination, thereby optimizing the drainage function while taking into account the ice storage capacity of the ice storage container 400.

[0148] In some embodiments, such as Figure 2 , Figure 3 and Figures 5-7 As shown, the ice storage container 400 also forms a water passage cavity 404, and the ice making container 300 has an overflow port 303 on the side adjacent to the opening. The bottom of the water passage cavity 404 has a drain port 405. The overflow port 303 is configured to always be vertically opposite to the water passage cavity 404 during the flipping process of the ice making container 300.

[0149] In this embodiment, such as Figure 2 , Figure 3 and Figures 5-7 As shown, the internal space of the ice storage container 400 can be divided into a relatively independent ice storage chamber 401 and a water passage chamber 404. Multiple ice-making columns 220 are vertically opposite to the ice storage chamber 401 of the ice storage container 400, and the multiple ice-making columns 220 and the water passage chamber 404 of the ice storage container 400 are staggered. The ice storage chamber 401 is used to receive ice blocks that fall off from the ice evaporator 200, while the water passage chamber 404 is used to receive water flowing out of the overflow port 303 of the ice storage container 300, and discharge this water into the water tank 500 through the bottom drain port 405.

[0150] The water passage cavity 404 can be distributed on at least one side of the ice storage cavity 401 along the front-back direction and left-right direction of the refrigeration equipment, and this application embodiment does not limit this.

[0151] As an example, such as Figure 5 As shown, the ice container 300 has overflow ports 303 on both sides adjacent to the opening.

[0152] As an example, the ice container 300 has an overflow port 303 on one of its sides adjacent to the opening.

[0153] One or more overflow ports 303 may be provided on one side of the ice container 300. "Multiple" means two or more. The shape of the overflow port 303 may be, but is not limited to, rectangular, waist-shaped, semi-circular or irregular shape. This application embodiment does not limit this.

[0154] In actual operation, during the ice-making process, the water tank 500 continuously supplies water to the ice-making container 300 through the water circuit assembly. When the water level rises to exceed the maximum capacity of the ice-making container 300, the excess water will overflow from the overflow port 303 of the ice-making container 300. The overflow port 303 is directly opposite the water passage cavity 404 of the ice storage container 400 below. The overflowing water falls into the water passage cavity 404 and then flows back to the water tank 500 through the drain port 405 at the bottom of the water passage cavity 404.

[0155] During the process of the ice container 300 being overturned and drained, the unfrozen water inside the ice container 300 will be discharged from the overflow port 303 under the action of gravity. Since the overflow port 303 is always aligned with the water passage cavity 404 below during the entire overturning process, the water discharged from the overflow port 303 during the overturning process also falls into the water passage cavity 404 and flows back to the water tank 500 through the drain port 405 at the bottom of the water passage cavity 404.

[0156] In related technologies, when ice makers drain water to remove ice, the water discharged from the ice-making container usually falls directly into the ice storage container below and mixes with the ice, failing to achieve effective ice-water separation. This results in poor ice quality and makes it difficult for users to remove ice. Furthermore, the drainage process easily generates significant splashing, which may splash onto the inner wall of the machine casing or other components, potentially leading to bacterial growth, odors, or electrical hazards over time.

[0157] Understandably, this application divides the ice storage container 400 into an ice storage chamber 401 and a water passage chamber 404. Throughout the entire ice-making and de-icing cycle, the water in the ice-making container 300 always flows into the water passage chamber 404, while the ice blocks fall into the ice storage chamber 401, achieving ice-water separation. Simultaneously, the water discharged from the ice-making container 300 first falls into the water passage chamber 404, which has a certain depth, and after buffering, flows out from the bottom drain outlet 405. Compared to falling directly into the water tank, this design makes the water flow into the water tank 500 more stable, significantly reducing the splash height.

[0158] The refrigeration equipment provided in this application embodiment, through the aforementioned separated ice storage chamber 401 and water passage chamber 404, allows the produced ice blocks to fall into the ice storage chamber 401 for storage, while the water overflowing during the ice-making process and the water discharged during the de-icing process are guided to the water passage chamber 404, realizing ice-water separation, thereby improving the quality of ice formation and the convenience of ice removal, and thus optimizing the user's user experience. At the same time, the water passage chamber 404 acts as a buffer for the water flow, allowing the water to flow out smoothly from the drain port 405 at the bottom of the water passage chamber 404 and fall into the water tank 500, greatly reducing the water flow speed and splash height, thereby effectively alleviating problems such as bacterial growth, odor, and moisture in other components caused by splashing water, and thus greatly improving the long-term hygiene and reliability of the ice maker 10.

[0159] In some embodiments, such as Figure 2As shown, the ice storage container 400 includes a partition 410 disposed between the ice storage cavity 401 and the water passage cavity 404, with the water passage cavity 404 located on the side of the ice storage cavity 401 away from the ice outlet 103.

[0160] The separator 410 can be integrally formed with the ice storage container 400 or designed separately; this application embodiment does not impose any restrictions on this.

[0161] In actual implementation, such as Figure 2 As shown, users can pull out or push in the ice storage container 400 through the ice outlet 103 to retrieve ice and clean the container. With the ice outlet 103 facing the front of the refrigeration equipment, the water passage cavity 404 is located behind the ice storage cavity 401. When the user pulls out the ice storage container 400 to retrieve ice, only the ice storage cavity 401 needs to be exposed, while the water passage cavity 404 is basically hidden inside the casing 100. The user will not see any small amount of ice or water that may remain in the water passage cavity 404. At the same time, when ice gets stuck when the ice storage container 400 is pulled out, the stuck ice can roll over the separator 410 into the rear water passage cavity 404 instead of falling directly into the water tank 500 below. The user will not see any residual ice when pulling out the water tank 500, further optimizing the user experience.

[0162] In related technologies, when ice is stuck, if the user pulls hard on the ice storage container, some ice will fall into the water tank. This may cause the user to see floating ice in the water tank, leading the user to mistakenly believe that the water tank is frozen. Or, the ice may fall inaccurately when it is being removed, which seriously affects the user experience and the user's judgment of the equipment quality.

[0163] The refrigeration device provided in this application embodiment, by setting the water passage cavity 404 on the side of the ice storage cavity 401 away from the ice outlet 103, when the user pulls out the ice storage container 400 through the ice outlet 103 to take out ice, only the ice storage cavity 401 can be seen, while the water passage cavity 404 is hidden inside the casing 100, so that the residual ice or water in the water passage cavity 404 is hidden from the user's sight. At the same time, the stuck ice will roll into the hidden water passage cavity 404 instead of falling directly into the water tank 500, avoiding the situation where the user pulls out the water tank 500 and sees the residual ice inside. Thus, it takes into account both functional practicality and cleanliness, thereby maximizing the user's visual perception and experience.

[0164] In some embodiments, such as Figure 2 , Figure 6 and Figure 7 As shown, the top height of the divider 410 is lower than the top height of the side wall on the ice storage container 400 that connects to the divider 410.

[0165] The height difference between the top of the separator 410 and the top of the side wall of the ice storage container 400 connected to the separator 410 is sufficient to allow the ice block to be completely released from the clamping state. Specifically, it can be adapted to the height of the ice block, and this application embodiment does not limit it.

[0166] For example, in some embodiments, the height difference between the top of the divider 410 and the top of the side wall of the ice storage container 400 that connects to the divider 410 can be half the height of the ice block.

[0167] For example, in other embodiments, the height difference between the top of the divider 410 and the top of the side wall of the ice storage container 400 that connects to the divider 410 can also be 2 / 3 of the ice block height.

[0168] In actual operation, when the ice in the ice storage container 400 accumulates too high, a narrow gap forms between the upper edge of the rear wall of the ice storage cavity 401 and the top wall of the ice extraction port 103 as the user pulls the ice storage container 400 outward. Some ice blocks slide to the top of the rear wall of the ice storage cavity 401, causing them to get stuck in this narrow gap and be squeezed from both sides. That is, the rear wall of the ice storage cavity 401 pushes forward, and the top wall of the ice extraction port 103 presses backward, preventing the ice storage container 400 from moving outward further. When the top height of the separator 410 is lower than the top height of the side wall of the ice storage container 400 connected to the separator 410, the reduced height of the rear wall of the ice storage cavity 401 allows the stuck ice blocks to fall vertically. Once ice jamming occurs, the user can slightly shake the ice storage container 400, causing the stuck ice blocks to undergo slight displacement due to the vibration, thus allowing them to smoothly pass over the separator 410 and roll into the water passage cavity 404. Once the stuck ice block enters the water-falling cavity, there is no longer any hard interference between the rear wall of the ice storage cavity 401 and the top wall of the ice extraction port 103, and the ice storage container 400 can be easily extracted.

[0169] The refrigeration equipment provided in this application embodiment, through the structural design that the top height of the partition 410 is lower than the top height of the side wall of the ice storage container 400 connected to the partition 410, provides an escape channel for ice blocks stuck when pulled out. There is no need to pull or tilt the ice storage container 400 forcefully; a slight shake can solve the ice jamming problem, making operation less strenuous and significantly improving the user experience. At the same time, it reduces structural deformation or wear caused by forced pulling, thereby extending the service life of the casing 100 and the ice storage container 400.

[0170] In some embodiments, such as Figure 2 and Figure 3 As shown, the separator 410 includes a first plate 411 and a second plate 412 connected together. The first plate 411 forms one side wall of the ice storage cavity 401, and the second plate 412 forms one side wall of the water passage cavity 404. A heat insulation space 407 is formed between the first plate 411 and the second plate 412.

[0171] In this embodiment, such as Figure 2 , Figure 3 and Figure 6 As shown, the first plate 411 and the second plate 412 are bent and connected to form an inverted V-shaped partition 410. The first plate 411 can form the rear wall of the ice storage cavity 401 and is used to contain the ice blocks inside the ice storage cavity 401. The second plate 412 can form the front wall of the water passage cavity 404. The first plate 411 and the second plate 412 can form an insulated space 407 with air as the heat insulation medium. This insulated space 407 can effectively reduce the heat transfer between the ice storage cavity 401 and the water passage cavity 404. On the one hand, it can slow down the melting rate of the ice blocks in the ice storage cavity 401, extend the ice storage time, and ensure the quality of the ice blocks. On the other hand, it can reduce the risk of the water in the water passage cavity 404 freezing due to absorbing the cold energy of the ice storage cavity 401, so as to prevent the water from freezing and blocking the drain outlet 405 and ensuring the normal operation of the water circulation.

[0172] The refrigeration equipment provided in this application embodiment, through the arrangement of the first plate 411 and the second plate 412, combined with the design of the heat insulation space 407, significantly increases the thermal resistance between the ice storage cavity 401 and the water passage cavity 404, greatly weakens the heat transfer between the ice storage cavity 401 and the water passage cavity 404 through the separator 410, helps to maintain a stable low temperature environment in the ice storage cavity 401, thereby effectively slowing down the melting rate of ice, maintaining a longer ice storage time and better ice quality, and effectively preventing the ice storage cavity 401 from overcooling the water passage cavity 404, thereby significantly reducing the risk of water freezing in the water passage cavity 404 or at the drain outlet 405, and maintaining the stability of the water circulation.

[0173] In some embodiments, such as Figure 4 and Figure 5 As shown, the ice maker 10 also includes a water guide trough 180.

[0174] The water guide channel 180 is installed on the housing 100. The water guide channel 180 is located above the ice storage container 400 and to the side of the ice making container 300 in the direction of flipping. The water guide channel 180 has a water outlet 1801 in the area away from the ice taking port 103. A water blocking plate 170 is provided on the lower edge of the water outlet 1801.

[0175] The water channel 180 is used to guide water splashed out of the ice-making container 300 to the outlet 1801, so that it returns to the water tank 500 below through the outlet 1801. As an example, Figures 2-4As shown, the water outlet 1801 is distributed on the water guide trough 180 in the area away from the ice extraction port 103. With the ice extraction port 103 facing the front of the refrigeration equipment, in other words, the water outlet 1801 of the water guide trough 180 is located in the rear area of ​​the water guide trough 180. In this way, the water guide trough 180 can concentrate and guide the received water flow to the rear water outlet 1801 for centralized discharge.

[0176] The outlet 1801 of the water guide trough 180 can be directly opposite the water passage 404 of the ice storage container 400 below. The overflowing water falls into the water passage 404 and then flows back to the water tank 500 through the drain 405 at the bottom of the water passage 404.

[0177] At the lower edge of the outlet 1801, the water guide trough 180 can be integrally formed or fixedly connected with a downward protruding water blocking plate 170. The water blocking plate 170 is used to provide a forced downward flow path for the water leaving the outlet 1801, so as to prevent the water from flowing to the outer bottom wall of the water guide trough 180.

[0178] The water guide channel 180 can be designed in various structural forms, including but not limited to U-shaped channels, V-shaped channels or irregular channels, etc., and the embodiments of this application do not limit it.

[0179] The height of the water-blocking plate 170 can be adjusted according to the actual water flow size and flow speed, so that the water-blocking plate 170 can take into account both the water blocking effect and the miniaturization requirement. This application embodiment does not limit this.

[0180] With the aforementioned water guide channel 180 and water baffle 170, the water flowing from the outlet 1801 flows along the water baffle 170 to the lower end, and under the action of gravity and surface tension, it detaches from the plate wall and drips directly into the water tank 500 below. This effectively blocks the path of water flowing along the outer bottom wall of the water guide channel 180 to the side wall of the casing 100 and then flowing forward. This significantly reduces the possibility of water from the water guide channel 180 overflowing into the room, thereby reducing odors and bacterial growth, and lowering the risk of component failure due to moisture. This optimizes the user experience and improves the reliability of the refrigeration equipment.

[0181] In some embodiments, such as Figure 4 , Figure 5 and Figure 7 As shown, the water guide channel 180 includes: a first water guide plate 181 and a water-blocking flange 182. One side of the first water guide plate 181 is connected to the housing 100; the water-blocking flange 182 is connected to the other side of the first water guide plate 181 and is bent upwards; wherein, a first notch 1821 is formed between the water-blocking flange 182 and the housing 100, the first notch 1821 is the water outlet 1801 of the water guide channel 180, and a water-blocking plate 170 is connected to the first water guide plate 181 and is bent downwards relative to the first water guide plate 181.

[0182] The first water guide plate 181 serves as the main load-bearing component of the water guide channel 180, used to receive and collect water flow. The first water guide plate 181 can be designed as a flat plate, an arc plate, or an inclined plate structure, and this embodiment does not impose any limitations on this.

[0183] The water-blocking flange 182 is connected to the edge of the first water guide plate 181 facing the movement path of the ice container 300. The water-blocking flange 182 can extend vertically or obliquely upward from the edge of the first water guide plate 181 to form a barrier, reducing the water flow from the side or splashing, so that the water flow is effectively constrained within the water guide channel 180.

[0184] The specific dimensions of the water-blocking flange 182 can be adjusted according to the flipping range and water volume of the ice-making container 300, and this application embodiment does not limit this.

[0185] In some embodiments, such as Figure 4 and Figure 5 As shown, the water-blocking plate 170 is inclined towards the ice-making container 300 from top to bottom.

[0186] In other words, the water-blocking plate 170 is tilted from top to bottom toward the center area of ​​the housing 100.

[0187] In actual implementation, such as Figure 4 and Figure 5 As shown, when water flows downward along the baffle plate 170, the inclined plate wall not only relies on gravity but also applies a guiding component towards the center of the casing 100 by changing the extension direction of the plate wall. This causes the water to concentrate in an area away from the side wall of the casing 100 and drip at the lower end of the baffle plate 170. Thus, for the water to cross the baffle plate 170, it must overcome gravity and move upward along the inclined plate surface, significantly increasing the path length and difficulty for the water to flow outward around the edge of the baffle plate 170.

[0188] The refrigeration equipment provided in this application embodiment, through the structural design of the water-blocking plate 170 being inclined from top to bottom toward the ice-making container 300, causes the water flow to drip more concentratedly into the middle area inside the casing 100, greatly increasing the difficulty for the water flow to cross the water-blocking plate 170 and flow along the outer bottom wall of the water guide channel 180, further reducing the probability of water leakage into the compartment, further reducing the risk of water accumulation in the compartment, keeping the compartment clean and dry, and achieving a more reliable leak-proof effect.

[0189] In some embodiments, such as Figures 6-8 As shown, the bottom of the water passage cavity 404 is decorated with concave and convex features.

[0190] The bottom of the water passage cavity 404 can have a regular concave-convex shape, such as a wave shape or a sawtooth shape, or the bottom of the water passage cavity 404 can have an irregular concave-convex shape. This application embodiment does not limit this.

[0191] In this embodiment, such as Figures 6-8 As shown, the bottom of the water passage cavity 404 can be in the form of a corrugated plate. The bottom wall of the water passage cavity 404 includes multiple protrusions 430 distributed along the width direction of the ice storage container 400 and protruding upwards. The multiple protrusions 430 can be integrally formed with the bottom wall. Multiple means two or more. A drainage space 406 is formed between two adjacent protrusions 430, providing a clear guiding channel for water flow, reducing the disorderly diffusion and long-term stagnation of water on the flat bottom wall, and guiding the rapid discharge of water. At the same time, in the event of ice jamming when the ice storage container 400 is pulled out or other abnormal situations, a few ice blocks may accidentally enter the water passage cavity 404. If the bottom is flat, the ice blocks may stay and directly block the drain outlet 405. However, the uneven bottom wall structure reduces the contact area between the bottom wall of the water passage cavity 404 and the ice blocks.

[0192] In this situation, the drainage space 406 can guide the water flow to more thoroughly flush, surround, and contact the ice blocks, significantly accelerating the melting speed of the ice blocks and allowing them to melt into water and flow away as quickly as possible. Furthermore, even if some unmelted ice blocks temporarily remain near the drain outlet 405, the uneven bottom of the water passage cavity 404 makes it difficult for the ice blocks to form a perfectly flush surface with the drain outlet 405, thus effectively avoiding the risk of the drain outlet 405 becoming blocked.

[0193] The refrigeration equipment provided in this application embodiment, by setting the bottom of the water passage 404 to be uneven, guides the water flow to quickly converge and discharge, accelerates the drainage speed, and thus improves the water circulation efficiency. At the same time, in the event of a small number of ice blocks accidentally entering the water passage 404 due to situations such as ice blockage caused by pulling out the ice storage container 400, the uneven bottom wall can not only accelerate the melting of the ice blocks, but also prevent the ice blocks from sticking to the bottom wall and blocking the drain outlet 405, thereby ensuring the stability of the water circulation.

[0194] In some embodiments, such as Figures 6-8 As shown, at least a portion of the recessed area at the bottom of the water passage cavity 404 is provided with a drain outlet 405.

[0195] It is understandable that, such as Figures 6-8As shown, the recessed area at the bottom of the water passage cavity 404 is the bottom of the drainage space 406 formed between two adjacent protrusions 430, and this position is the lowest point of the bottom wall of the water passage cavity 404. If the drain outlet 405 is located on the protrusion 430 or in a flat area that is not the lowest point, the recessed area may form a local puddle, causing the water to not be completely drained. When the drain outlet 405 is distributed in the recessed area, the drain outlet 405, in conjunction with the guiding effect of the inclined wall of the protrusion 430, can allow the water in the water passage cavity 404 to be discharged quickly and evenly, reducing water residue.

[0196] In some embodiments, each recessed area is provided with a drain outlet 405; in other words, each drainage space 406 has a drain outlet 405 at its bottom.

[0197] In some embodiments, depending on factors such as the size of the water passage cavity 404 and the strength requirements of the ice storage container 400, a drain outlet 405 may be selectively provided in a portion of the recessed area, that is, a drain outlet 405 may be provided at the bottom of a portion of the drainage space 406.

[0198] The refrigeration equipment provided in this application embodiment has a structural design in which at least part of the recessed area at the bottom of the water passage 404 is provided with a drain outlet 405, so that the water flow can naturally converge along the recessed area, reducing the dead corners of water accumulation in the water passage 404, further accelerating the drainage rate, and further improving the circulation efficiency.
