Description

Technical Field

[0001] This application relates to the field of home appliance technology, and more particularly to a refrigerator. Background Technology

[0002] As an indispensable home appliance in modern families, refrigerators have become increasingly sophisticated and functional with technological advancements, meeting users' needs for food preservation, storage, and other aspects.

[0003] In conceiving and implementing this application, the applicant discovered at least the following problems: Currently, refrigerators include a cabinet and an inner liner housed within the cabinet. The inner liner forms a refrigeration compartment for storing items at low temperatures. The refrigerator uses a refrigeration system to cool the refrigeration compartment. During operation, the evaporator of the refrigeration system produces condensate. Typically, an evaporation dish is provided inside the refrigerator to collect this condensate. Evaporation tubes are usually placed inside the evaporation dish, and the condensate is evaporated through thermal radiation from the evaporation tubes. However, because the condensate contains impurities and is generally acidic, it severely corrodes the steel evaporation tubes. When the evaporation tubes corrode, refrigerant leaks further, causing the refrigerator to malfunction.

[0004] The preceding description is intended to provide general background information and does not necessarily constitute prior art. Utility Model Content

[0005] The main objective of this application is to provide a refrigerator that reduces corrosion of the evaporator tube, increases the service life of the evaporator tube, overcomes the bottleneck problem of inaccurate evaporator tube dimensions, and improves the installation stability of the evaporator tube.

[0006] To achieve the above objectives, this application provides a refrigerator, comprising:

[0007] The enclosure includes a refrigeration compartment;

[0008] The door is movably connected to the cabinet and is configured to open and close the refrigeration compartment;

[0009] The evaporating dish assembly, located at the bottom of the chamber, includes:

[0010] An evaporating dish is used to collect defrost water. The evaporating dish has the following characteristics:

[0011] The insertion groove is located on the outer bottom of the evaporating dish and extends along the length or width of the evaporating dish.

[0012] An evaporating tube, at least a portion of which is inserted into the insertion groove along the extension direction of the insertion groove, such that at least a portion of the evaporating tube is in contact with the bottom of the evaporating dish.

[0013] The beneficial effects of this application are as follows: By using the structure of the evaporating dish assembly, the evaporating tube is placed outside the bottom of the evaporating dish, so that the evaporating tube does not come into direct contact with the condensate or defrosting water in the evaporating dish, which can reduce the corrosion of the evaporating tube and improve its service life. In addition, the evaporating tube is inserted into the bottom of the evaporating dish through the insertion groove, which breaks through the bottleneck problem of inaccurate evaporating tube size, improves the installation stability of the evaporating tube, and has high assembly efficiency and high overall practicality.

[0014] Based on the above technical solution, the following improvements can be made to this application.

[0015] In some alternative embodiments, the insertion groove extends along the width of the evaporating dish;

[0016] There are multiple insertion slots, which are spaced apart along the length of the evaporating dish so that the evaporating tube is coiled on the outer side of the bottom of the evaporating dish.

[0017] The above technical solution has the following advantages or beneficial effects: by making the evaporator tube fit tightly against the bottom outer side of the evaporating dish, the insertion groove design can ensure good contact between the evaporator tube and the evaporating dish, thereby improving the heat conduction efficiency and making more effective use of the heat of the evaporator tube to accelerate the evaporation of condensate in the evaporating dish.

[0018] In some alternative implementations, the insertion slot is elongated; and / or,

[0019] The evaporating dish is an injection molded part.

[0020] The above technical solution has the following advantages or beneficial effects: the elongated insertion groove can provide a larger contact area, making the heat conduction between the evaporator tube and the evaporator dish more efficient, which helps to transfer heat to the evaporator dish more quickly, thereby accelerating the evaporation of condensate.

[0021] In some alternative embodiments, the evaporating dish further comprises:

[0022] The insertion part protrudes into the inside of the evaporating dish and has a receiving cavity for accommodating the evaporating tube;

[0023] An isolation section, located at the bottom of the evaporating dish, at least partially blocks the opening of the receiving cavity to form an insertion groove with the insertion section.

[0024] The above technical solution has the following advantages or beneficial effects: the insertion part provides a dedicated space to accommodate the evaporation tube. Through the design of the accommodating cavity, the stability of the evaporation tube in the evaporation dish can be ensured, preventing it from shifting or loosening during operation.

[0025] In some alternative implementations, the refrigerator further includes:

[0026] A cooling tray is used to support the evaporating dish assembly. An isolation section is located between the evaporating tube and the tray along the depth direction of the evaporating dish.

[0027] The above technical solution has the following advantages or beneficial effects: the tray provides a stable support platform, which enables the evaporating dish assembly to be firmly fixed inside the refrigerator, helps to reduce vibration and displacement, and ensures the stability of the system during operation.

[0028] In some alternative implementations, the isolation section is a plate-like structure with weight-reduction holes.

[0029] The above technical solution has the following advantages or beneficial effects: the design of the weight-reducing hole directly reduces the amount of material used in the isolation part, thereby reducing its overall weight. This not only helps to reduce the total weight of the refrigerator, but may also reduce transportation and installation costs.

[0030] In some alternative embodiments, there are multiple weight-reducing holes, which are spaced apart in the isolation section.

[0031] The above-mentioned technical solution has the following advantages or beneficial effects: the design of multiple weight-reducing holes can significantly reduce the amount of material used in the insulation section, thereby further reducing its overall weight. This helps to reduce the total weight of the refrigerator and lower transportation and installation costs.

[0032] In some alternative embodiments, the refrigerator further includes a refrigeration assembly for cooling the refrigeration compartment, the refrigeration assembly including: a first heat exchange port and a second heat exchange port;

[0033] The evaporator tube includes: a first evaporator tube, inserted into the insertion slot;

[0034] The second evaporator tube has its first end connected to the first end of the first evaporator tube, and its second end connected to the first heat exchange port.

[0035] The third evaporator tube, the first end of the second evaporator tube is connected to the second end of the first evaporator tube, and the second end of the second evaporator tube is connected to the second heat exchange port;

[0036] The second and third evaporation tubes are mounted on the outer wall of the evaporation dish.

[0037] The above technical solution has the following advantages or beneficial effects: The first evaporator tube is inserted into the insertion slot, ensuring close contact with the bottom outer wall of the evaporating dish, thus improving heat transfer efficiency. The second and third evaporator tubes are respectively attached to the outer wall of the evaporating dish, with the second evaporator tube connected to the first heat exchange port and the third evaporator tube connected to the second heat exchange port, forming an effective heat exchange loop and ensuring efficient circulation of the refrigerant in the system.

[0038] In some alternative embodiments, the evaporating dish further comprises:

[0039] The first slot is connected to the insertion slot and is located at the first end of the outer wall of the evaporating dish. The first slot extends along the depth direction of the evaporating dish. Part of the structure of the second evaporating tube is locked in the first slot, and the other part of the structure of the second evaporating tube is suspended above the evaporating dish.

[0040] The second slot is connected to the insertion slot and is located at the second end of the outer wall of the evaporating dish. The second slot extends along the depth direction of the evaporating dish. Part of the structure of the third evaporating tube is locked in the second slot, and another part of the structure of the third evaporating tube is suspended above the evaporating dish.

[0041] The above technical solution has the following advantages or beneficial effects: the first and second slots are located at both ends of the outer wall of the evaporating dish, providing a stable fixing position so that parts of the second and third evaporating tubes can be firmly fixed to the evaporating dish. This fixing method reduces the displacement or loosening of the evaporating tubes due to vibration during operation, and improves the stability of the system.

[0042] In some alternative embodiments, at least one of the second and third evaporator tubes is bent.

[0043] The above-mentioned technical solution has the following advantages or beneficial effects: the bent design can effectively absorb and mitigate vibrations caused by compressor operation or external vibrations. This structure can reduce the transmission of vibrations through the elastic deformation of the bent portion, thereby protecting the evaporator tube and other connecting components.

[0044] The refrigerator provided in this application includes a cabinet having a refrigeration compartment; a door movably connected to the cabinet and configured to open and close the refrigeration compartment; and an evaporator assembly disposed at the bottom of the cabinet. The evaporator assembly includes: an evaporator for collecting defrost water, the evaporator having: an insertion groove located on the outer side of the bottom of the evaporator, the insertion groove extending along the length direction or the width direction of the evaporator; and an evaporator tube, at least a portion of which is inserted into the insertion groove along the extension direction of the insertion groove, such that at least a portion of the evaporator tube is in contact with the bottom of the evaporator.

[0045] By utilizing the structure of the evaporating dish assembly, the evaporating tube is placed externally to the bottom outside of the evaporating dish, preventing it from directly contacting the condensate or defrosting water in the dish. This reduces corrosion of the evaporating tube and extends its service life. Furthermore, the evaporating tube is inserted into the bottom outside of the evaporating dish via a connector slot, overcoming the bottleneck problem of inaccurate evaporating tube dimensions. This improves the installation stability of the evaporating tube, and also results in high assembly efficiency and overall practicality. Attached Figure Description

[0072] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, 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, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. All other obtained embodiments are within the scope of protection of this application. In the absence of conflict, the following embodiments and features can be combined with each other.

[0076] Currently, the evaporation dish contains an evaporation tube, which evaporates defrost water through heat radiation. However, defrost water contains impurities and is generally acidic, which severely corrodes the steel evaporation tube. When the evaporation tube corrodes, it will further leak refrigerant, causing the refrigerator to malfunction.

[0077] To overcome the shortcomings of the prior art, the refrigerator provided in this application, through the structure of the evaporator assembly, places the evaporator tube outside the bottom of the evaporator, so that the evaporator tube does not come into direct contact with the condensate or defrost water in the evaporator, which can reduce corrosion of the evaporator tube and improve its service life. In addition, the evaporator tube is inserted into the bottom outside of the evaporator through the insertion slot, which breaks through the bottleneck problem of inaccurate evaporator tube size, can improve the installation stability of the evaporator tube, and has high assembly efficiency and high overall practicality.

[0080] like Figures 1 to 6 As shown, this application embodiment provides a refrigerator 100, including:

[0081] The enclosure 110 has a refrigeration compartment;

[0082] The door 120 is movably connected to the cabinet 110 and is configured to open and close the refrigeration compartment;

[0083] An evaporating dish assembly 130 is disposed at the bottom of the housing 110, and the evaporating dish assembly 130 includes:

[0084] Evaporating dish 131, used to collect defrost water, has the following characteristics:

[0085] The insertion groove 1313 is located on the outer bottom of the evaporating dish 131, and the insertion groove 1313 extends along the length direction or the width direction of the evaporating dish 131.

[0086] Evaporation tube 132, at least a portion of which is inserted into insertion groove 1313 along the extension direction of insertion groove 1313, such that at least a portion of evaporation tube 132 is attached to the bottom of evaporation dish 131.

[0087] With the above-described configuration, the refrigerator 100 of this embodiment, through the structure of the evaporating dish assembly 130, places the evaporating tube 132 externally to the bottom outer side of the evaporating dish 131, so that the evaporating tube 132 does not directly contact the condensate or defrosting water in the evaporating dish 131, thereby reducing corrosion of the evaporating tube 132 and improving its service life. In addition, the evaporating tube 132 is inserted into the bottom outer side of the evaporating dish 131 through the insertion slot 1313, which overcomes the bottleneck problem of inaccurate evaporating tube 132 dimensions, improves the installation stability of the evaporating tube 132, and has high assembly efficiency and high overall practicality.

[0088] It should be noted that the following provides a detailed explanation of each structure.

[0089] [Box 110]

[0090] The refrigerator 100 of this application embodiment may include a cabinet 110 and a door 120. The cabinet 110 may be configured with a refrigeration compartment. The refrigeration compartment has an opening for storing food and other items. There may be one or more refrigeration compartments. When there are multiple refrigeration compartments, the multiple refrigeration compartments may be divided into a refrigerator compartment, a freezer compartment, or a variable temperature compartment, etc.

[0091] In some embodiments, the refrigerator compartment and the freezer compartment may be arranged alternately in the vertical direction or alternately in the horizontal direction, thereby forming a double-door refrigerator 100 or a side-by-side refrigerator 100, without limitation.

[0092] For example, the refrigerator body 110 may include an outer shell and an inner liner, the outer shell defining the external boundary of the refrigerator 100. The inner liner may be disposed within and connected to the outer shell. The inner liner may be recessed inward to form a cooling compartment. An insulation layer may be filled between the outer shell and the inner liner, which can insulate the cooling compartment, thereby reducing the energy consumption of the refrigerator 100.

[0093] The box 110 adopts a hollow cuboid structure. It is understood that in other embodiments, the box 110 may also adopt a hollow shell structure of other shapes.

[0094] [Gate 120]

[0095] It should be noted that the door 120 can be connected to the cabinet 110 to open or close the refrigeration compartment.

[0096] A door 120 is disposed on the front surface of the enclosure 110 to enclose the refrigeration compartment. The door 120 is configured to open and close the refrigeration compartment, meaning it can open and close the front opening of the enclosure 110. Doors 120 can be correspondingly assigned to refrigeration compartments; that is, each refrigeration compartment can have one or more doors 120. The number of refrigeration compartments and doors 120, as well as the function of the refrigeration compartments, can be selected based on specific circumstances. One door 120 can be assigned to the same refrigeration compartment. Alternatively, two doors 120 can be assigned to the same refrigeration compartment.

[0097] In some possible implementations of this application, the door 120 can be rotatably connected to the housing 110 about the height direction Z of the housing 110. The door 120 can be pulled or pushed to rotate relative to the housing 110, thereby opening or closing the refrigeration compartment.

[0098] In some embodiments, the door 120 is a rotating door structure. The door 120 is rotatably disposed on the front side of the cabinet 110, and in this case, the door 120 can be used as a general door structure, such as a refrigerator door, a freezer door, etc.

[0099] Specifically, the door 120 and the cabinet 110 can be connected by a hinge so that the door 120 of the refrigerator 100 can rotate around the axis of the hinge, thereby opening and closing the door 120 of the refrigerator 100 and opening and closing the corresponding refrigeration compartment.

[0100] In some embodiments, the door 120 can also be a sliding door structure. The door 120 is slidably disposed on the front side of the cabinet 110, and in this case, the door 120 can be used as a drawer door. Specifically, guide rails (not shown in the figure) are respectively provided on the left and right inner side walls of the cabinet liner, and the door 120 is connected to the guide rails on both sides, thereby realizing the sliding function of the door 120 and realizing the opening and closing of the refrigeration compartment by extending and retracting the guide rails.

[0101] [Refrigeration Component 140]

[0102] In some alternative embodiments, the refrigerator 100 further includes:

[0103] The refrigeration assembly 140 is used to refrigerate the refrigeration chamber, and the refrigeration assembly 140 includes a tray 141 to support the evaporating dish assembly 130.

[0104] The above technical solution has the following advantages or beneficial effects: the tray 141 provides a stable support platform, which enables the evaporating dish assembly 130 to be firmly fixed inside the refrigerator 100, which helps to reduce vibration and displacement and ensure the stability of the system during operation.

[0105] In some embodiments, a refrigeration assembly 140 (not shown) is provided inside the housing 110. The refrigeration assembly 140 is used to provide refrigeration for the interior of the refrigerator 100 to maintain a low-temperature environment in each refrigeration compartment so that it can preserve or freeze food at low temperatures.

[0106] The refrigeration assembly 140 includes a compressor, condenser, evaporator, and throttling device. The specific structure and connections of the refrigeration assembly 140 can be found in related technical documents and will not be elaborated upon here. The evaporator provides different amounts of cooling capacity to different types of storage spaces, resulting in different temperatures within each type of storage space.

[0107] To facilitate cooling, the evaporator is used to exchange heat with the cooling room, thereby maintaining a low temperature in the cooling room. In the refrigeration cycle, the compressor is connected to the condenser. The compressor compresses the refrigerant into a high-temperature, high-pressure gas, which is then discharged into the condenser. In the condenser, the refrigerant continuously releases heat to the surrounding space, gradually condensing into a liquid. After being throttled and depressurized, it flows into the evaporator, where it continues to vaporize, absorbing heat and cooling the room.

[0108] For example, the temperature inside a refrigerator is generally between 2°C and 10°C, with an optimal range of 4°C to 7°C. The temperature inside a freezer is generally between -22°C and -14°C. Different types of items have different optimal storage temperatures, and consequently, different suitable storage spaces. For example, fruits and vegetables are suitable for storage in the refrigerator or crisper compartment, while meat is suitable for storage in the freezer.

[0109] Since the evaporator needs to defrost after working for a period of time, the condensate produced will collect at the bottom of the inner tank. At this time, the evaporation dish 131 can collect this condensate and receive the condensate flowing down from the inner tank.

[0110] In some embodiments, the tray 141 may support structures such as the condenser and compressor in the refrigeration assembly 140.

[0111] [Evaporating dish assembly 130]

[0112] like Figures 1 to 6 As shown, it should be noted that the refrigerator 100 also includes an evaporation dish assembly 130, which is located at the bottom of the refrigerator 100. Its main purpose is to collect the condensate or defrost water inside the refrigerator 100 and evaporate it to prevent it from being discharged outside the refrigerator 100.

[0113] Specifically, the evaporating dish assembly 130 includes an evaporating dish 131 for collecting condensate or defrost water inside the refrigerator 100.

[0114] Furthermore, during operation, moisture inside the refrigerator 100 condenses into water droplets, which flow into the evaporation dish 131 through the drain pipe. By effectively collecting and evaporating the condensate, the evaporation dish 131 helps prevent water stains from appearing on the bottom of the refrigerator 100 or on the floor.

[0115] For example, the evaporating dish 131 is box-shaped and can be rectangular, circular, or elliptical, etc. Specifically, depending on the internal structure of the refrigerator 100, the evaporating dish 131 may be designed as an irregular shape to better adapt to the space.

[0116] For example, the evaporating dish 131 has a insertion groove 1313, which is provided at the bottom of the evaporating dish 131 and located on the outside of the evaporating dish 131, wherein the insertion groove 1313 extends along the length direction or the width direction of the evaporating dish 131.

[0117] That is, the extension direction of the insertion groove 1313 is parallel to the length direction of the evaporating dish 131, or the extension direction of the insertion groove 1313 is parallel to the width direction of the evaporating dish 131.

[0118] In other embodiments, the extension direction of the insertion groove 1313 may be at an angle to the length direction of the evaporating dish 131, meaning that the insertion groove 1313 is inclined.

[0119] Specifically, the evaporating dish assembly 130 also includes an evaporating tube 132, which uses the heat emitted by the evaporating tube 132 to evaporate the defrosting water or condensate in the evaporating dish 131, preventing it from being discharged outside the refrigerator 100.

[0120] It should be noted that the evaporation tube 132 is inserted into the insertion groove 1313 along the extension direction of the insertion groove 1313, thereby fixing the evaporation tube 132. After the evaporation tube 132 is fixed, it can be attached to the bottom of the evaporation dish 131, which means that the heat of the evaporation tube 132 can be better utilized for evaporation.

[0121] It should be noted that the evaporator tube 132 is installed using a plug-in method, which offers higher stability compared to the snap-fit ​​installation method used in some existing solutions. A detailed analysis follows:

[0122] If a settling groove is made on the evaporating dish 131, the evaporating tube 132 is generally not precisely sized during manufacturing, so after actual production, the evaporating tube 132 cannot be placed into the settling groove, or even if it is placed in, it will still fall out, resulting in poor stability. Therefore, multiple clamping parts are usually added for fixing, but multiple clamps make the evaporating tube 132 easy to fall out, resulting in low assembly efficiency and high cost. In contrast, this application uses an insertion method with a plug-in slot 1313 for fixing, which overcomes the bottleneck problem of the inaccurate size of the evaporating tube 132 and can improve the installation stability of the evaporating tube 132.

[0123] Figure 7 This is a second-view structural schematic diagram of the evaporator assembly in a refrigerator provided in an embodiment of this application, as shown below. Figures 5 to 7 As shown, in some alternative embodiments, the insertion slot 1313 extends along the width direction of the evaporating dish 131;

[0124] There are multiple insertion slots 1313, which are spaced apart along the length of the evaporating dish 131 so that the evaporating tube 132 is coiled on the outer side of the bottom of the evaporating dish 131.

[0125] The above technical solution has the following advantages or beneficial effects: by making the evaporation tube 132 fit tightly against the bottom outer side of the evaporation dish 131, the design of the insertion groove 1313 can ensure good contact between the evaporation tube 132 and the evaporation dish 131, thereby improving the heat conduction efficiency and making more effective use of the heat of the evaporation tube 132 to accelerate the evaporation of condensate in the evaporation dish 131.

[0126] In some embodiments, the insertion slots 1313 extend along the width direction of the evaporating dish 131, and a plurality of insertion slots 1313 are spaced apart along the length direction of the evaporating dish 131.

[0127] In other embodiments, the insertion slots 1313 extend along the length of the evaporating dish 131, and a plurality of insertion slots 1313 are spaced apart along the width of the evaporating dish 131.

[0128] The insertion slot 1313 allows the evaporator tube 132 to be arranged compactly on the bottom outer side of the evaporation dish 131 in a spiral manner, optimizing space utilization and reducing the space occupied inside the refrigerator 100, enabling a more compact design. By optimizing the layout and contact area of ​​the evaporator tube 132, the insertion slot 1313 design helps improve the evaporation efficiency of moisture in the evaporation dish 131, thereby reducing the risk of moisture accumulation and keeping the refrigerator 100 dry and hygienic.

[0129] It should be noted that, Figure 7 As shown, X represents the width direction of evaporating dish 131, and Y represents the length direction of evaporating dish 131.

[0130] like Figure 7 As shown, the evaporation tube 132 is coiled on the outside of the bottom of the evaporation dish 131, which can be understood as the evaporation tube 132 being arranged in an S-shape, that is, multiple S-shaped connections are located at the bottom of the evaporation dish 131.

[0131] The insertion slot 1313 provides a fixed position for the evaporator tube 132, preventing displacement or loosening during operation, thereby improving the structural stability and reliability of the entire system. This design makes the installation and maintenance of the evaporator tube 132 more convenient. The insertion slot 1313 provides a clear installation path, simplifying the assembly process, and also allows for easier disassembly and reinstallation when maintenance is required.

[0132] In some alternative embodiments, in order to increase the contact area between the evaporator tube 132 and the evaporating dish 131 and improve the heat transfer efficiency, the evaporator tube 132 may adopt a flat structure, that is, the cross-section of the evaporator tube 132 may be elliptical.

[0133] In some alternative embodiments, the insertion slot 1313 is elongated.

[0134] The above technical solution has the following advantages or beneficial effects: the elongated insertion groove 1313 can provide a larger contact area, making the heat conduction between the evaporator tube 132 and the evaporator dish 131 more efficient, which helps to transfer heat to the evaporator dish 131 more quickly, thereby accelerating the evaporation of condensate.

[0135] The elongated insertion slot 1313 can more evenly distribute the weight and stress of the evaporator tube 132, reduce local stress concentration, and improve the stability and durability of the overall structure. The elongated design provides a continuous path, making the installation of the evaporator tube 132 more intuitive and convenient. Installers can more quickly insert the evaporator tube 132 into the insertion slot 1313, reducing installation time and complexity.

[0136] Furthermore, the elongated insertion slot 1313 allows the evaporator tube 132 to contact the evaporator dish 131 over a wider area, thereby improving evaporation efficiency. The evaporator tube 132 can fit more tightly against the bottom outer side of the evaporator dish 131, optimizing space utilization, saving space inside the refrigerator 100, and providing more space for the arrangement of other components.

[0137] Figure 8 This is a first-view cross-sectional view of the evaporating dish assembly in a refrigerator provided in an embodiment of this application. Figure 9 for Figure 8 A magnified view of a portion of section II. Figure 10 A cross-sectional view from a second perspective of the evaporating dish assembly in a refrigerator provided in an embodiment of this application.

[0138] like Figures 8 to 10 As shown, in some optional embodiments, the evaporating dish 131 further comprises:

[0139] Insertion portion 1311 protrudes into the inner side of evaporating dish 131, and insertion portion 1311 has a receiving cavity for accommodating evaporating tube 132;

[0140] The isolation section 1312 is located at the bottom of the evaporating dish 131. At least part of the isolation section 1312 blocks the opening of the receiving cavity to form an insertion groove 1313 with the insertion section 1311.

[0141] The above technical solution has the following advantages or beneficial effects: the insertion part 1311 provides a dedicated space to accommodate the evaporation tube 132. Through the design of the accommodating cavity, the stability of the evaporation tube 132 in the evaporation dish 131 can be ensured, preventing it from shifting or loosening during operation.

[0142] It should be noted that, as Figure 8 and Figure 9 As shown, the insertion part 1311 is a protruding structure on the inner side of the evaporating dish 131, and the insertion part 1311 is a concave structure on the outer side of the bottom of the evaporating dish 131.

[0143] Since the evaporator tube 132 is tightly surrounded by the insertion part 1311, heat can be transferred more effectively from the evaporator tube 132 to the evaporating dish 131, which helps to improve the evaporation efficiency of the condensate.

[0144] The combination of the insertion part 1311 and the isolation part 1312 makes the installation of the evaporator tube 132 more intuitive and simple. During maintenance, the evaporator tube 132 can also be more easily disassembled and reinstalled, reducing the complexity of maintenance.

[0145] like Figure 10 As shown, in some optional embodiments, the isolation part 1312 has a plate-like structure, and weight reduction holes 13121 are formed on the isolation part 1312.

[0146] The above technical solution has the following advantages or beneficial effects: the design of the weight reduction hole 13121 directly reduces the amount of material used in the isolation part 1312, thereby reducing its overall weight. This not only helps to reduce the total weight of the refrigerator 100, but may also reduce transportation and installation costs.

[0147] By creating weight-reducing holes 13121 in the isolation section 1312, the amount of material used can be reduced, thus lowering production costs. Although the weight-reducing holes 13121 reduce material usage, a well-designed hole shape and distribution can achieve weight reduction without significantly affecting structural strength.

[0148] In some alternative embodiments, there are multiple weight-reducing holes 13121, which are spaced apart in the isolation portion 1312.

[0149] The above-mentioned technical solution has the following advantages or beneficial effects: the design of multiple weight-reducing holes 13121 can significantly reduce the amount of material used in the isolation section 1312, thereby further reducing its overall weight. This helps to reduce the total weight of the refrigerator 100 and reduce transportation and installation costs.

[0150] By rationally distributing multiple weight-reducing holes 13121, material savings can be maximized without significantly affecting structural integrity.

[0151] Multiple weight-reducing holes 13121 are spaced apart, allowing the material between the holes to provide the necessary support and strength. By carefully designing the size, shape, and spacing of the holes, the structural integrity of the isolation section 1312 can be maintained while reducing weight.

[0152] Figure 11 This is a cross-sectional view of the evaporator dish assembly and tray in a refrigerator provided in an embodiment of this application.

[0153] like Figure 11 As shown, along the depth direction of the evaporating dish 131, the isolation section 1312 is located between the evaporating tube 132 and the tray 141.

[0154] It should be noted that the isolation section 1312 is located between the evaporator tube 132 and the support plate 141. On the one hand, it plays a buffering and protective role, which can prevent the support plate 141 from causing direct physical pressure or damage to the evaporator tube 132 and extend the service life of the evaporator tube 132.

[0155] On the other hand, the design of the isolation section 1312 helps optimize the heat conduction path, ensuring that the heat from the evaporator tube 132 can be effectively transferred to the evaporating dish 131, without being absorbed or lost by the tray 141. In other words, the presence of the isolation section 1312 effectively separates the evaporator tube 132 from the tray 141, reducing the possibility of heat being transferred to the tray 141 through the heat conduction path. This insulation effect ensures that the heat from the evaporator tube 132 is primarily used for the evaporation of condensate in the evaporating dish 131, rather than being absorbed or lost by the tray 141.

[0156] In addition, the isolation section 1312 can also play a role in shock absorption, reducing the transmission of vibrations generated by the operation of the compressor and other refrigeration components 140 to the evaporating dish 131 and the tray 141, thereby reducing noise.

[0157] In some embodiments, the tray 141 and the isolation section 1312 can be manufactured using durable and economical materials, reducing overall costs while providing reliable performance.

[0158] Figure 12 This is an exploded schematic diagram of the evaporating dish assembly in a refrigerator provided in an embodiment of this application. Figure 13This is a third-view structural schematic diagram of the evaporating dish assembly in a refrigerator provided in an embodiment of this application. Figure 14 for Figure 13 A magnified view of a portion of point III. Figure 15 for Figure 13 A magnified view of a portion of point IV in the middle.

[0159] like Figures 12 to 15 As shown, in some optional embodiments, the refrigeration assembly 140 includes a first heat exchange port and a second heat exchange port;

[0160] Evaporator tube 132 includes:

[0161] The first evaporator tube 1321 is inserted into the insertion slot 1313;

[0162] The second evaporator 1322 has its first end connected to the first end of the first evaporator 1321, and its second end connected to the first heat exchange port.

[0163] The first end of the third evaporator 1323 and the second evaporator 1322 are connected to the second end of the first evaporator 1321, and the second end of the second evaporator 1322 is connected to the second heat exchange port.

[0164] The second evaporation tube 1322 and the third evaporation tube 1323 are fitted onto the outer wall of the evaporation dish 131.

[0165] The above technical solution has the following advantages or beneficial effects: The first evaporator tube 1321 is inserted into the insertion slot 1313, ensuring close contact with the bottom outer wall of the evaporating dish 131, thus improving heat transfer efficiency. The second evaporator tube 1322 and the third evaporator tube 1323 are respectively attached to the outer wall of the evaporating dish 131, with the second evaporator tube 1322 connected to the first heat exchange port and the third evaporator tube 1323 connected to the second heat exchange port, forming an effective heat exchange loop and ensuring efficient circulation of the refrigerant in the system.

[0166] The first end of the second evaporator 1322 is connected to the first end of the first evaporator 1321, and the second end of the second evaporator 1322 is connected to the first heat exchange port; the first end of the third evaporator 1323 is connected to the second end of the first evaporator 1321, and the second end of the third evaporator 1323 is connected to the second heat exchange port, allowing the refrigerant to flow in different paths, thus optimizing the flow and heat exchange process of the refrigerant.

[0167] With a reasonable layout of the evaporator tubes 132 and the connection of the heat exchange ports, the refrigerant can be distributed and flow more evenly, improving the efficiency of the entire refrigeration system and helping to reduce the internal temperature of the refrigerator 100 more quickly and evenly.

[0168] The second evaporator tube 1322 and the third evaporator tube 1323 are fitted onto the outer wall of the evaporating dish 131. This compact design saves space and makes the internal layout of the refrigerator 100 more reasonable and efficient.

[0169] Furthermore, by tightly fixing the second evaporator tube 1322 and the third evaporator tube 1323 to the evaporating dish 131, the possibility of pipe vibration and displacement is reduced, thereby improving the reliability and durability of the system.

[0170] like Figure 13 , Figure 14 as well as Figure 15 As shown, in some optional embodiments, the evaporating dish 131 further comprises:

[0171] The first slot 1314 is connected to the insertion slot 1313, and the first slot 1314 is located at the first end of the outer wall of the evaporating dish 131. The first slot 1314 extends along the depth direction of the evaporating dish 131. Part of the structure of the second evaporating tube 1322 is engaged in the first slot 1314, and another part of the structure of the second evaporating tube 1322 is suspended above the evaporating dish 131.

[0172] The second slot 1315 is connected to the insertion slot 1313, and the second slot 1315 is located at the second end of the outer wall of the evaporating dish 131. The second slot 1315 extends along the depth direction of the evaporating dish 131. Part of the structure of the third evaporating tube 1323 is engaged in the second slot 1315, and another part of the structure of the third evaporating tube 1323 is suspended above the evaporating dish 131.

[0173] The above technical solution has the following advantages or beneficial effects: the first slot 1314 and the second slot 1315 are located at both ends of the outer wall of the evaporating dish 131, providing a stable fixing position so that parts of the second evaporating tube 1322 and the third evaporating tube 1323 can be firmly fixed on the evaporating dish 131. This fixing method reduces the displacement or loosening of the evaporating tube 132 due to vibration during operation, and improves the stability of the system.

[0174] The proper fixing and layout of the evaporation tube 132 ensures effective contact with the evaporation dish 131, thereby improving the heat transfer efficiency.

[0175] The design of the first slot 1314 makes the installation process of the second evaporator tube 1322 simpler and more intuitive. Similarly, the design of the second slot 1315 makes the installation process of the third evaporator tube 1323 simpler and more intuitive. During maintenance, the second evaporator tube 1322 and the third evaporator tube 1323 can also be more easily disassembled and reinstalled, reducing the complexity and time of operation.

[0176] In some alternative embodiments, at least one of the second evaporator tube 1322 and the third evaporator tube 1323 is bent.

[0177] The above-mentioned technical solution has the following advantages or beneficial effects: the bent design can effectively absorb and mitigate vibrations caused by compressor operation or external vibrations. This structure can reduce the transmission of vibrations through the elastic deformation of the bent part, thereby protecting the evaporator tube 132 and other connecting components.

[0178] During transportation or operation, the refrigerator 100 may be subjected to impacts. The bent evaporator tube 132 can absorb impact forces through the deformation of its bent portion, reducing direct impact on pipes and connecting parts, lowering the risk of damage, extending the service life of the evaporator tube 132, reducing the probability of failure due to fatigue or physical damage, effectively reducing noise generated during operation, and improving the user experience.

[0179] The bent structure provides a degree of flexibility, allowing the evaporator tube 132 to better adapt to spatial layout and position adjustments during installation. Although the bent design is primarily for vibration damping and shock absorption, it also ensures the effectiveness of the heat conduction path without affecting the heat exchange efficiency of the evaporator tube 132.

[0180] Figure 16 This is a schematic diagram of the structure of the mold for manufacturing the evaporating dish provided in an embodiment of this application. Figure 17 This is an exploded view of the mold portion used to manufacture the evaporating dish, provided in an embodiment of this application. Figure 18 This is an exploded view of the mold for manufacturing the evaporating dish provided in an embodiment of this application. Figure 19 An explosion diagram of the slider and evaporating dish in the mold is provided for the embodiments of this application.

[0181] like Figures 16 to 19 As shown, in some alternative embodiments, the evaporating dish 131 is an injection molded part.

[0182] It should be noted that the evaporating dish 131 is an injection molded part formed by injection molding through mold 200.

[0183] In some embodiments, the mold 200 includes a female mold 210, a male mold 220, and a slider 230. The male mold 220 has multiple injection ports 221. By injecting plastic into the injection ports 221, after cooling, the insertion groove 1313 is ejected from the mold by the slider 230 through the oil cylinder. When the male mold 220 and the female mold 210 are opened respectively, the evaporating dish 131 is completed.

[0184] In some embodiments, multiple injection ports 221 are spaced apart along the length of the male mold 220, which can reduce the impact pressure on the slider 230 in the horizontal direction, reduce the deformation of the slider 230, and thus avoid mold cavity deformation, thereby improving the quality of the evaporating dish 131.

[0185] In some embodiments, there are two sliders 230, which are located on both sides of the male mold 220 respectively, and the two sliders 230 form an insertion groove 1313.

[0186] It should be noted that the slider 230 includes a body 231 and multiple insert plates 232. The multiple insert plates 232 are spaced apart along the extension direction of the body 231. The shape of the insert plate 232 matches the shape of the insertion groove 1313. That is, when the slider 230 is pushed out, the insert plate 232 is exposed and its insertion groove 1313 is gradually formed.

[0187] In some embodiments, the insert plate 232 is not a conventional plate structure and the thickness of the insert plate 232 is small. In order to avoid the risk of deformation due to high injection force during injection molding, a support block 211 is provided on the female mold 210. The support block 211 abuts against the insert plate 232, so that the top-down injection pressure of the slider 230 can be transmitted to the female mold 210, thereby avoiding the risk of deformation of the slider 230.

[0188] It should be noted that the evaporating dish 131 can be produced quickly and in large quantities using mold 200. This method is suitable for mass production and can significantly reduce the production cost per unit.

[0189] The evaporating dish 131 can be made of various plastic materials, such as polypropylene (PP), polyethylene (PE), ABS, etc. These materials have good corrosion resistance and durability, making them suitable for the humid environment inside the refrigerator 100. Plastic materials are generally lightweight, which helps to reduce the overall weight of the refrigerator 100 and lower transportation and installation costs.

[0190] The refrigerator provided in this application includes a cabinet having a refrigeration compartment; a door movably connected to the cabinet and configured to open and close the refrigeration compartment; and an evaporator assembly disposed at the bottom of the cabinet. The evaporator assembly includes: an evaporator for collecting defrost water, the evaporator having: an insertion groove located on the outer side of the bottom of the evaporator, the insertion groove extending along the length direction or the width direction of the evaporator; and an evaporator tube, at least a portion of which is inserted into the insertion groove along the extension direction of the insertion groove, such that at least a portion of the evaporator tube is in contact with the bottom of the evaporator.

[0191] By utilizing the structure of the evaporating dish assembly, the evaporating tube is placed externally to the bottom outside of the evaporating dish, preventing it from directly contacting the condensate or defrosting water in the dish. This reduces corrosion of the evaporating tube and extends its service life. Furthermore, the evaporating tube is inserted into the bottom outside of the evaporating dish via a connector slot, overcoming the bottleneck problem of inaccurate evaporating tube dimensions. This improves the installation stability of the evaporating tube, and also results in high assembly efficiency and overall practicality.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.
