Description

Technical Field

[0001] This utility model relates to the field of refrigeration equipment technology, and in particular to a freezer. Background Technology

[0002] Horizontal freezers are a common type of refrigeration equipment widely used in commercial and residential environments for storing and preserving food. Their structure typically includes an inner liner, a shell, and a compressor compartment. The inner liner forms the storage space, while the compressor compartment houses the core components of the refrigeration system. In traditional horizontal freezer assembly, the inner liner is usually inserted into the shell from top to bottom, and the compressor compartment is located within the stepped space of the inner liner. Electrical components inside the freezer (such as fans, heating elements, and sensors) are connected to the components in the compressor compartment via wiring harnesses.

[0003] However, when the inner liner steps are connected to the press chamber, the limited line of sight makes it difficult for operators to accurately align the two parts, resulting in a complicated and time-consuming assembly process.

[0004] In particular, inserting the wiring harness into the press chamber requires passing it through specific holes and connecting it to the corresponding terminals. However, the confined space and obstructed view make the operation difficult and prone to misalignment.

[0005] When assembling the inner liner and the outer shell, the wiring harness may be squeezed or rubbed by surrounding parts, causing damage to the wiring and affecting the electrical performance and service life of the freezer.

[0006] Furthermore, after the inner liner is installed, foaming is required. If the wiring harness is not properly secured and gaps are left, foaming material will overflow into the press chamber during the foaming process.

[0007] These issues increase production difficulty, reduce assembly efficiency, and may affect the overall quality of the freezer and its stability in subsequent use. Utility Model Content

[0049] The present invention will now be described in detail with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the protection scope of the present invention.

[0050] It should be understood that terms such as “above,” “over,” “below,” and “under” used herein to indicate spatial relative position are for illustrative purposes to describe the relationship of one unit or feature relative to another unit or feature as shown in the accompanying drawings. The terms “spatial relative position” may be intended to include different orientations of the equipment in use or operation other than those shown in the figures.

[0051] One embodiment of this utility model provides an improved structural design for a freezer that optimizes the installation of the inner liner, especially the inner liner installation at the wiring harness.

[0052] Example 1

[0053] This embodiment provides a freezer 100, such as Figure 1 As shown, it includes an inner liner 10, a press chamber 20, a wire harness fixing component 30, and a wire harness 40.

[0054] The inner liner 10 has a storage space 101 formed on the inside, and the inner liner 10 has a stepped portion 11, with a stepped space 110 formed on the outside of the stepped portion 11.

[0055] The press chamber 20 is housed within the stepped space 110. The press chamber 20 includes a nacelle cover 21, on which a through hole 211 is provided.

[0056] The wire harness fastener 30 includes a connecting part 31, a fixing body 32, and a guiding part 33. The connecting part 31 is fixedly connected to the inner liner 10. The fixing body 32 is provided with a wire hole 324. The fixing body 32 covers part of the through hole 211 and exposes the wire hole 324. During the assembly process of the inner liner 10 and the shell 50, it extends into the press space 210 to guide the wire harness fastener 30 to align with the through hole 211.

[0057] The wire harness 40 is used to connect electrical components. At least a portion of the wire harness 40 in the press chamber 20 passes through the through hole 211 and the wire hole 324 and extends into the stepped space 110.

[0058] To clearly express the position and direction described in this embodiment, up and down are defined with reference to the direction of gravity. The freezer 100 in this embodiment can be a horizontal freezer 100, which is generally placed on a horizontal surface with the opening of the storage space 101 facing upwards. The freezer 100 is basically a cuboid structure, with the left and right sides along its length and the front and back sides along its width. For a description of the directions, please refer to... Figure 1 and 2 As shown.

[0059] like Figure 1 and 2 As shown, the step portion 11 is located on one side or one end of the inner liner 10, and the step space 110 formed below the step portion 11 is used to accommodate the compressor chamber 20.

[0060] like Figure 1 , 3 As shown in Figures 6 and 7, the compressor compartment 20 is the core component housing space of the refrigeration system of the freezer 100, and the compartment cover 21 is the top or side covering structure of the compressor compartment 20.

[0061] like Figure 1 and 2 As shown, the wire harness fastener 30 can be made of heat-resistant plastic or metal, and the connecting part 31 is fixed to the inner liner 10 by means of screwing, snapping, or bonding.

[0062] like Figure 4 and 5 As shown, there can be one or more wire holes 324, which can pass through multiple sets of wire harnesses 40.

[0063] The wire harness 40 may include multiple wires and terminals. The size of the wire hole 324 may be the same as the cross-section of the wire harness 40 or the cross-section of the terminal. The appropriate size of the wire hole 324 may be set as needed.

[0064] The wiring harness 40 can connect to electrical components such as fans, heating wires or sensors inside the freezer 100 to provide power or transmit signals.

[0065] In addition, the freezer 100 also includes the casing 50, such as Figure 1 As shown. During the assembly process of the inner liner 10 and the housing 50, the terminals of the wire harness 40 are first inserted into the wire hole 324 and fixed. Then, the inner liner 10 is placed into the housing 50 from top to bottom, and the wire harness 40 extends into the press space 210 inside the press chamber 20 through the through hole 211 of the engine compartment cover 21.

[0066] Since the fixed body 32 covers part of the through hole 211 and exposes the wire hole 324, the area of ​​the through hole 211 is larger than the area of ​​the wire hole 324, which makes it easier for the wire harness 40 to pass downward into the through hole 211.

[0067] This embodiment, through the design of the wire harness fixing component 30, allows the wire harness 40 to be pre-organized and fixed before assembly. Furthermore, during the installation of the inner liner 10, the wire harness 40 can be easily inserted into the press chamber 20. In the prior art, because the wire harness 40 is relatively soft, during the installation of the inner liner 10 and the shell 50, the internal wiring is blindly connected, making it difficult to accurately insert into the press chamber 20. The freezer 100 of this embodiment avoids the tedious organization steps caused by the scattered wire harness 40 in traditional assembly, significantly reducing assembly time and improving production efficiency.

[0068] Meanwhile, since the position of the wire harness 40 is fixed, it can be ensured that the wire harness 40 passes through the predetermined path, avoiding the problem of misalignment in blind assembly, making the assembly of the inner liner 10 and the compressor chamber 20 smoother; protecting the wire harness 40 from squeezing or wear, improving the reliability of electrical component connections and the durability of the freezer 100.

[0069] In addition, the wiring harness fastener 30 makes full use of the layout of the step space 110 and the compressor compartment 20, making the management of the wiring harness 40 more orderly, reducing the waste of internal space of the freezer 100, and improving the compactness of the overall structure.

[0070] Furthermore, such as Figure 5 As shown, a first positioning part 325 is provided on the side of the fixed body 32 facing the compressor chamber 20, such as... Figure 6As shown, the cabin cover 21 includes a second positioning part 212, and the first positioning part 325 is positioned and docked with the second positioning part 212.

[0071] The first positioning part 325 can be a protrusion, a slot, or a guide post structure, and the second positioning part 212 can be the edge of the through hole 211, a groove, or a corresponding boss structure. For example, the first positioning part 325 is a plurality of protrusions, and the second positioning part 212 is the edge area of ​​the through hole 211. The protrusions and the edge of the through hole 211 are matched to limit the fit, ensuring that the wire harness fixing member 30 and the cabin cover 21 are aligned during assembly.

[0072] The limiting docking design of the first positioning part 325 and the second positioning part 212 enables the wire harness fixing part 30 and the cabin cover plate 21 to be quickly and accurately aligned during assembly, ensuring the axial consistency of the wire hole 324 and the through hole 211, avoiding the offset or jamming of the wire harness 40 during installation, and improving the accuracy and stability of assembly.

[0073] The limiting function of the first positioning part 325 and the second positioning part 212 reduces the need for manual adjustment and alignment, enabling assembly personnel to quickly complete the docking of the wire harness fixing part 30 and the cabin cover 21, reducing the difficulty of operation and improving assembly efficiency.

[0074] In addition, the limiting docking can restrict the movement of the wire harness fixing component 30 relative to the cabin cover 21 after assembly, preventing misalignment caused by vibration or external force during use and enhancing the overall structural reliability. Especially when the refrigerator 100 is foaming, the limiting of the first positioning part 325 and the second positioning part 212 can also ensure the fixed position when the foaming material exerts a squeezing effect on the internal components.

[0075] In this embodiment, as Figure 5 and 6 As shown, the first positioning part 325 is configured as a positioning protrusion, and the second positioning part 212 is configured as the edge of the through hole 211, with the positioning protrusion inserted into the through hole 211.

[0076] The positioning protrusion extends from the fixing body 32 toward the press chamber 20, and its cross-sectional shape (such as circular or rectangular) matches the contour of the edge of the through hole 211. In this embodiment, both the positioning protrusion and the through hole 211 have square cross-sections. During assembly, the positioning protrusion is inserted into the through hole 211 and aligned with the contour of the edge of the through hole 211, forming a tight limiting fit.

[0077] The design of aligning the positioning protrusion with the edge contour of the through hole 211 further enhances the positioning accuracy of the wire harness fixing component 30 and the nacelle cover plate 21, prevents misalignment during assembly, ensures that the wire harness 40 passes through smoothly, and improves assembly efficiency.

[0078] Furthermore, such as Figure 5As shown, during the assembly of the inner liner 10 and the shell 50, the guide part 33 guides the wire harness fixing part 30 to align with the through hole 211.

[0079] In practice, the guide section 33 can be a long strip or an arc-shaped structure, making it easy for operators to hold and adjust.

[0080] The guide part 33 plays a guiding role during assembly, enabling the wire harness fixing part 30 to be quickly aligned with the through hole 211, reducing the difficulty of repeated manual adjustments and significantly improving assembly speed and efficiency.

[0081] Furthermore, the guide part 33 defines the insertion path of the wire harness fixing part 30, ensuring that the alignment of the wire harness fixing part 30 and the through hole 211 is consistent each time assembly, thereby enhancing the standardization and consistency in the production process.

[0082] In addition, the design of the guide part 33 passing through the through hole 211 on the engine compartment cover 21 and being inserted into the compressor compartment 20 plays a guiding role in the installation of the inner liner 10 and the housing 50. That is, the guide part 33 not only guides the installation of the wiring harness fixing part 30 itself, but also guides the installation of the inner liner 10.

[0083] During the installation of existing freezers, the inner liner 10 may be misaligned due to the lack of effective alignment methods when it is placed into the outer shell 50, requiring repeated fine adjustments. However, with the help of the guide part 33, the installation of the inner liner 10 can be guided, especially the installation of the wiring harness.

[0084] In this embodiment, as Figure 5 As shown, the guide part 33 includes a handle 331, which can be held, gripped, or pinched by the user.

[0085] After the inner liner 10 and the outer shell 50 are assembled, the handle 331 is used to continue adjusting the relative positions of the first positioning part 325 and the second positioning part 212 within the press chamber 20.

[0086] The handle 331 is easy to operate and has a certain length. The length of the handle 331 can be inserted into the press chamber 20, ensuring that the position of the wire harness fixing member 30 can be adjusted by operating the handle 331 inside the press chamber 20.

[0087] The design of inserting the handle into the press chamber 20 allows the assembly personnel to operate from the side of the press chamber 20 to adjust the position of the wire harness fixing piece 30, improving the convenience and flexibility of assembly in a confined space.

[0088] Furthermore, the handle passes through the through hole 211 and extends into the press space 210, providing a longer guide path and ensuring more precise alignment between the wire harness fastener 30 and the through hole 211, reducing the possibility of assembly deviation and improving overall production efficiency.

[0089] After the inner liner 10 and the outer shell 50 are assembled, the guide part 33 is used to continue to adjust the relative position of the first positioning part 325 and the second positioning part 212. That is to say, both the wire harness fixing part 30 and the inner liner 10 have a certain degree of flexibility. After the inner liner 10 falls from top to bottom to the lowest position, the relative position of the first positioning part 325 and the second positioning part 212 can still be adjusted by moving the guide part 33.

[0090] Generally, in the existing technology, after the inner liner 10 falls to the lowest position, either the position is not adjusted, or the position of the inner liner 10 is observed through some gaps, and then the position of the inner liner 10 is adjusted by repeatedly lifting and lowering it. However, for some tiny gaps, it is difficult to observe them, and it is relatively difficult to move the inner liner 10 over such a small distance, which may result in excessive movement.

[0091] In this embodiment, because the guide part 33 is provided, when the positions of the wire harness fixing part 30 and the press chamber 20 are not aligned and there is a gap, the worker only needs to move the guide part 33 at the press chamber 20 to adjust the relative position of the first positioning part 325 and the second positioning part 212 until... Figure 5 and 6 The rectangular protrusions in the molded parts fall into the rectangular holes, thus completing the accurate installation and preventing the foaming material from flowing into the press chamber 20 through gaps during the subsequent foaming process if the part is not installed correctly. Adjustment of this position does not require operation of the inner liner 10, and the adjustment method is more intuitive, solving the problem of inconvenient adjustment of the inner liner 10 after assembly in existing technologies.

[0092] Furthermore, such as Figure 2 As shown, the inner liner 10 includes an end wall 13 located at the end of the stepped space 110 and a side wall 14 on the side, and the wire harness fastener 30 is fixedly connected to both the end wall 13 and the side wall 14.

[0093] For example, the connecting part 31 is designed as an L-shaped structure, such as Figure 4 and 5 As shown, one end is fixed to the end wall 13 by bolts, and the other end is connected to the side wall 14 by a snap fastener to ensure bidirectional fixation.

[0094] The wire harness fastener 30 is simultaneously fixed to both the end wall 13 and the side wall 14, enhancing the stability of the installation through bidirectional constraint and effectively preventing displacement or detachment caused by loosening of a single point of fixation during assembly or operation. This bidirectional fixation effectively constrains the wire harness 40 at both the end and side, reducing its degree of freedom within the stepped space 110, preventing it from becoming scattered or compressed, and improving the overall orderliness of management.

[0095] This design takes into account the assembly requirements of different freezer 100 structures, while improving the stability of the wiring harness fastener 30 in complex environments and enhancing the long-term reliability of the freezer 100.

[0096] Furthermore, the connecting part 31 includes a first connecting wall 311 and a second connecting wall 312. The first connecting wall 311 is fixedly connected to the end wall 13, and the second connecting wall 312 is fixedly connected to the side wall 14.

[0097] The first connecting wall 311 and the second connecting wall 312 can be arranged at a certain angle (e.g., 90 degrees) to form a stable support structure. Figure 4 and 5 As shown, the first connecting wall 311 and the second connecting wall 312 can be connected by an arc.

[0098] The first connecting wall 311 and the second connecting wall 312 are fixed to the end wall 13 and the side wall 14 respectively, forming a multi-point support structure, which greatly enhances the tensile and shear resistance of the wire harness fixing component 30 and ensures its stability during the operation of the freezer 100.

[0099] The split-wall design of the connector 31 allows for the selection of different fixing methods (such as bolts or clips) depending on the specific structure of the end wall 13 and side wall 14, improving assembly flexibility and compatibility. The double-wall structure disperses the stress borne by the wire harness fixing member 30, avoiding stress concentration problems that may occur with single-point fixing, and extending the service life of the fixing member.

[0100] like Figure 2 , 5 As shown, the inner liner 10 is provided with a first mating part 15, and the wire harness fixing member 30 is provided with a second mating part 34. The first mating part 15 and the second mating part 34 are connected by a mutually interlocking concave-convex structure.

[0101] For example, the first mating part 15 is a raised strip on the inner liner 10, and the second mating part 34 is a groove on the wire harness fixing member 30, with the raised strip inserted into the groove to form a fitting connection.

[0102] The interlocking design of the concave and convex structure enables the wire harness fastener 30 to provide high friction and limiting effect, ensuring that the wire harness fastener 30 is not easy to loosen or fall off after assembly, thus improving the reliability of the structure.

[0103] like Figure 11 and 12 As shown, the inner liner 10 in this embodiment can be made of metal or high-strength plastic material, or it can be assembled using a variety of materials through a splicing process.

[0104] Using metal materials provides excellent thermal conductivity and structural strength, ensuring the inner liner is not easily deformed during use and maintains temperature uniformity. High-strength plastic materials are easy to process into complex shapes, reducing production difficulty. By combining the advantages of both through a splicing process, the metal parts ensure strength and thermal conductivity, while the plastic parts allow for special structural designs, thereby optimizing performance, improving production efficiency, and reducing costs.

[0105] The inner liner includes a splicing section and a surrounding panel section, which are spliced ​​together to form a accommodating chamber. At least part of the splicing section is made of plastic, and the surrounding panel section is made of metal.

[0106] The side panels are made of metal to ensure the overall structural strength of the inner liner and meet the durability requirements of the freezer. The joints are made of plastic, allowing for easy fabrication into specific shapes (such as stepped sections) to meet the special design requirements of the inner liner. This combination of metal and plastic design improves performance and optimizes the manufacturing process.

[0107] The enclosure includes a first enclosure and a second enclosure, which are respectively located on both sides of the splicing section along the length of the horizontal freezer.

[0108] The first and second enclosure panels are placed side by side on both sides of the splicing section, making the inner liner structure more flexible and adaptable to layouts where the stepped section is located on the side of the press chamber rather than on top. Furthermore, this assembly structure breaks down the original large inner liner into three smaller structures, significantly reducing the size requirements of the processing equipment, thus greatly reducing hoisting equipment and production costs. It also facilitates assembly and subsequent maintenance, improving the convenience of production and use.

[0109] The splicing section includes a stepped section, which creates a lower side and a higher side at the bottom of the splicing section. A first panel is connected to the lower side of the splicing section, and a second panel is connected to the higher side of the splicing section.

[0110] The height difference design of the stepped section meets the layout requirement that the stepped section be located on the side of the press chamber rather than on top. The plastic parts are easy to mold into a stepped structure, while the metal enclosure is connected to it to ensure overall stability, taking into account both functionality and durability.

[0111] Figure 11 and 12 In the middle, the top of the second panel is provided with a splicing notch, which is located on the side near the splicing part, and the shape of the splicing notch matches the shape of the splicing part.

[0112] The splicing notch ensures a tighter connection between the second panel and the splicing section. The notch shape precisely matches the splicing section, improving splicing accuracy and strength, effectively preventing loosening or deformation during use, and enhancing the stability and reliability of the inner liner. Furthermore, it accommodates the layout requirement that the stepped section is located on the side of the press chamber rather than above it, allowing the second panel on the right side to be raised higher and facilitating the formation of an air duct above the splicing section on the first panel.

[0113] After the first and second panels are joined together with the splicing part, the top of the second panel is higher than the top of the first panel, and the splicing notch of the second panel is flush with the top of the first panel.

[0114] The splicing section also includes a first splicing structure and a second splicing structure, such as Figure 12 As shown, the first splicing structure is located on the side facing the first enclosure panel, as... Figure 11 As shown, the second splicing structure is disposed on the side facing the second enclosure. The first splicing structure is configured as a ring of insertion grooves that mate with the edge of the first enclosure, with the edge of the first enclosure inserted into the first splicing structure. The second splicing structure is configured as a ring of insertion grooves that mate with the edge of the second enclosure, with the edge of the second enclosure inserted into the second splicing structure.

[0115] The insertion slot design significantly enhances the connection strength between the metal panel and the plastic joint, provides a larger contact area, improves the sealing of the joint, effectively prevents cold air leakage or external heat transfer, and improves the heat preservation performance and energy efficiency of the freezer.

[0116] The insertion slot has a U-shaped cross-section and some protrusions inside, so that the first panel can be stably fixed after being inserted into the first splicing structure and the second panel can be inserted into the second splicing structure.

[0117] The inner liner is formed by combining metal and plastic components. The metal components serve as the main body of the inner liner, possessing good thermal conductivity and high structural strength, making them less prone to uneven temperature distribution and deformation under external forces. The plastic components are easy to process and mold, facilitating the creation of specialized structures to meet the specific design requirements of the inner liner. The combination of metal and plastic components facilitates both processing and assembly.

[0118] Furthermore, the first mating part 15 is configured as a flange surrounding the bottom of the inner liner 10, and the second mating part 34 is configured as a groove that matches the shape of the flange, with the flange inserted into the groove.

[0119] In this embodiment, the flange can be built into the bottom of the inner liner 10. The bottom of the inner liner 10 is spliced ​​by inserting a bottom plate and a side plate. The insertion position forms a flange. The flange protrudes outward from the bottom of the inner liner 10 to form a continuous ring structure. Its cross-section can be rectangular, trapezoidal or other shapes.

[0120] In this embodiment, the groove design on the wire harness fixing member 30 matches the cross-sectional shape of the flange. During assembly, the wire harness fixing member 30 aligns the groove with the flange and applies pressure, causing the flange to embed into the groove, forming a mating connection.

[0121] This structure enhances the fixing strength of the connection part 31. The annular flange provides uniform support for the wire harness fixing part 30, ensuring that it is fixed in the entire circumference, resulting in good fixing effect and improving the stability and durability of long-term use.

[0122] like Figure 2 As shown, the inner liner 10 is provided with an evaporator compartment 12, and the freezer 100 includes several sets of evaporator heating wires 60 for heating the evaporator compartment 12, and the wiring harness 40 is electrically connected to the several sets of evaporator heating wires 60.

[0123] The wiring harness 40 is electrically connected to the evaporator heating wire 60 through the wire hole 324 and the through hole 211 to provide it with power. In specific implementations, the evaporator heating wire 60 can be a resistance wire or a PTC (positive temperature coefficient) heating element, and the terminals of the wiring harness 40 and the terminals of the heating wire are reliably connected by plugging or soldering.

[0124] The evaporator heating wire 60 is attached to the bottom of the evaporator compartment 12, or it can be placed inside the evaporator compartment 12.

[0125] In this embodiment, the evaporator compartment 12 is as follows: Figure 2 As shown, the device includes a cabin 121 and a bottom plate 122. An evaporator is placed in the evaporation space between the cabin 121 and the bottom plate 122. An evaporator heating wire 60 is laid on the side of the bottom plate 122 away from the evaporator and extends along the extension direction of the bottom plate 122.

[0126] This installation method, which extends flat along the direction of the base plate 122, can cover the bottom of the base plate 122 as much as possible, and also ensure that each section of the evaporator heating wire 60 is in contact with the base plate 122, thus avoiding heat concentration or waste in local areas of the evaporator heating wire 60.

[0127] The heating wire is fixed to the base plate 122, which can be used as a heat transfer medium to evenly transfer the heat generated by the heater to the evaporator above. This effectively avoids the problem of local hot spots that may occur when heating directly, thus ensuring a more uniform and reliable defrosting process.

[0128] The cabin 121 is made of plastic, while the base plate 122 is made of sheet metal. The plastic cabin 121 has the advantage of being easy to mold for complex structures, making it convenient to manufacture various structures. The sheet metal base plate 122, with its excellent thermal conductivity, ensures efficient heat transfer to the evaporator, achieving uniform heat transfer and reducing energy consumption.

[0129] In this embodiment, the cabin 121 and the bottom plate 122 can be produced by insert injection molding. The sheet metal bottom plate 122 is pre-fixed in an appropriate position in the injection mold, and then plastic is injected to form the inner liner 10. After the mold is opened, the insert is tightly wrapped and embedded in the bottom plate 122 by the cooled and solidified plastic inner liner 10.

[0130] like Figure 2 As shown, in this embodiment, the evaporator heating wire 60 is attached to the base plate 122 in a serpentine shape. The serpentine structure allows the heating wire to cover a large area and ensures the uniformity of heat distribution. This effectively prevents overheating in some areas and ensures that the entire evaporator receives sufficient heat, achieving efficient defrosting.

[0131] The serpentine layout can adapt to the inclined and concave sections of the base plate 122, and the bending design of the heating wire ensures uniform heat distribution in different areas. For example, by optimizing the turning radius and bending angle, local heat accumulation is avoided.

[0132] The evaporator heating wire 60 is attached to the side of the base plate 122 away from the evaporator. The evaporator heating wire 60 is as far away from the space inside the evaporator compartment 12 as possible, reducing the direct entry of heat into the space inside the evaporator compartment 12 and the storage space 101, reducing the temperature rise and energy consumption in these areas, and reducing the impact on the internal temperature distribution and storage quality of the freezer 100.

[0133] Water flowing down from the evaporator typically falls onto the upper surface of the base plate 122, while the evaporator heater on the lower surface avoids direct contact with the water, thus improving safety.

[0134] The evaporator heating wire 60 attached to the lower surface of the base plate 122 can make the heat of the entire evaporator heating wire 60 more uniform, improving energy efficiency and defrosting uniformity during the defrosting process.

[0135] like Figure 3 As shown, the evaporator compartment 12 includes an evaporator fan 70 and a fan heating wire, and the wiring harness 40 electrically connects the evaporator fan 70 and the fan heating wire.

[0136] The evaporator fan 70 promotes the circulation of cold air within the freezer 100, while the fan heating wire heats the fan blades during defrosting to prevent icing. The wiring harness 40 is electrically connected to the evaporator fan 70 and the fan heating wire through the wire hole 324 and the through hole 211, providing them with power and control signals.

[0137] The wiring harness 40 can be divided into multiple strands, which are respectively connected to the terminals of the fan motor and the heating wire to ensure independent power supply for each component. The wiring harness 40 electrically connects the evaporator fan 70 and the fan heating wire to ensure the normal operation of the fan and the heating wire, thereby improving the overall performance of the evaporator compartment 12.

[0138] In this embodiment, the evaporator compartment 12 is located on the side of the compressor compartment 20. The wiring harness 40 passes through the through hole 211 of the nacelle cover plate 21 and the wire hole 324 of the wiring harness fixing member 30 from the side of the compressor compartment 20, and extends laterally to connect to the electrical components in the evaporator compartment 12.

[0139] In other embodiments, the evaporator compartment 12 may also be located above the compressor compartment 20. The wiring harness 40 passes through the through hole 211 of the nacelle cover plate 21 and the wire hole 324 of the wiring harness fastener 30 from the lower compressor compartment 20, and extends upward to connect to the electrical components in the evaporator compartment 12.

[0140] Furthermore, such as Figure 4 As shown, the wire harness 40 includes terminals that connect to electrical components, and the cross-section of the wire hole 324 matches the shape of the cross-section of the terminal.

[0141] For example, if the terminal is a rectangular plug, the wire hole 324 is designed as a rectangular hole; if the terminal is a round plug, the wire hole 324 is designed as a round hole, to ensure that the terminal can be tightly embedded in the wire hole 324 and fixed.

[0142] The design of the wire hole 324, which matches the shape of the terminal, allows the terminal to fit tightly when passing through, preventing the terminal from shaking or loosening in the hole and improving the stability of the electrical connection.

[0143] Furthermore, the different shapes of the wire holes 324 correspond to different types of terminals, effectively preventing the incorrect terminals from being inserted during assembly, thus improving the accuracy and efficiency of assembly.

[0144] The tight fit between the terminal and the wire hole 324 reduces friction and pulling of the wire harness 40 at the wire hole 324, reduces the risk of wear on the insulation layer of the wire harness 40, and extends the service life of the wire harness 40.

[0145] Furthermore, the naval cover 21 is provided with a plurality of through holes 211, the shape of each through hole 211 being adapted to the shape of the terminal passing through the through hole 211.

[0146] Before the inner liner 10 is assembled with the housing 50, the terminals of the wiring harness 40 are pre-inserted into the through holes 211 and fixed. In practice, the through holes 211 can be designed in different shapes such as rectangles and circles to match different terminals. This ensures that each terminal is inserted into the correct through hole 211, avoiding incorrect or missing insertions and improving the accuracy and reliability of the electrical connection.

[0147] Before assembling the inner liner 10 and the outer shell 50, the terminals of the wire harness 40 are pre-installed in the through holes 211. The design of pre-inserting the terminals into the through holes 211 allows the installation to be completed before the inner liner 10 and the outer shell 50 are assembled. This way, during the process of installing the inner liner 10 into the outer shell 50, it is only necessary to assemble the wire harness fixing piece 30 into place to complete the installation of the wire harness 40.

[0148] Furthermore, such as Figure 3 and 4 As shown, the fixed body 32 includes a top wall 321, an extension 323 and a bottom wall 322. The extension 323 is connected between the top wall 321 and the bottom wall 322. The distance between the bottom of the step 11 and the cabin cover 21 is equal to the distance between the top wall 321 and the bottom wall 322.

[0149] The top wall 321 is connected to the inner liner 10, the bottom wall 322 faces the cabin cover 21, the extension 323 serves as a support structure, and the fixed body 32 fits tightly with the cabin cover 21 during assembly, avoiding loosening caused by excessive gaps or assembly difficulties caused by excessively small gaps, thereby improving the stability and sealing of the structure.

[0150] The freezer 100 also includes foam filling between the wiring harness fastener 30 and the cabin cover 21, the foam sealing the gap between the bottom wall 322 and the cabin cover 21.

[0151] The foam can be made of closed-cell foam material, which has good elasticity and sealing properties, and is pressed between the bottom wall 322 and the cabin cover 21 during assembly.

[0152] The foam effectively seals the gap between the bottom wall 322 and the cabin cover 21, preventing the foam material from overflowing during the foaming process of the refrigerator 100 insulation layer, ensuring the integrity of the insulation layer, and improving the insulation performance of the refrigerator 100.

[0153] The elastic properties of the foam can absorb vibrations during the operation of the freezer 100, reducing friction and noise between the wiring harness fastener 30 and the chassis cover 21, thus improving user comfort. Furthermore, the foam sealing layer prevents dust and moisture from entering, avoids the leakage of the foam material, protects the wiring harness 40 and electrical components, and enhances the durability of the freezer 100 in harsh environments.

[0154] Furthermore, such as Figure 3 As shown, the extension 323 includes an extension body 3231 and a plurality of support ribs 3232. The extension body 3231 is connected between the top wall 321 and the bottom wall 322, and the support ribs 3232 are arranged perpendicular to the extension body 3231.

[0155] The extension body 3231 has a plate-like structure, and the supporting ribs 3232 are reinforcing ribs arranged along the length of the extension body 3231 to improve the bending and torsional resistance of the extension 323, prevent the fixing body 32 from deforming under external force, and ensure the stability of the wire harness fastener 30 during assembly and use. At the same time, it reduces the amount of material used and lowers the weight and production cost of the wire harness fastener 30.

[0156] Example 2

[0157] like Figure 7 As shown, the difference between this embodiment and embodiment 1 is that the inner liner 10 includes an end wall 13 located at the end of the stepped space 110, and the wire harness fixing member 30 is fixedly connected to the end wall 13.

[0158] Figure 7 The end wall 13 is the leftmost wall of the inner liner 10. The connecting part 31 can be fixed to the end wall 13 by bolts or by engaging with the pre-set slot on the end wall 13 by a snap fastener to achieve a stable connection. The through hole 211 on the cabin cover 21 is set in the corresponding position.

[0159] This embodiment optimizes the management of the wire harness 40 at the end of the stepped space 110 by fixing the wire harness fixing member 30 to the end wall 13 of the inner liner 10, reducing the crossing of the wire harness 40 and improving the convenience of assembly and maintenance.

[0160] Example 3

[0161] like Figure 8 As shown, the difference between this embodiment and embodiment 1 is that the inner liner 10 includes a side wall 14 located on the side of the stepped space 110, and the side wall 14 includes a front side wall 141. The wire harness fixing member 30 of embodiment 3 is only fixedly connected to the front side wall 141.

[0162] Figure 8 The front side wall 141 is the frontmost wall of the inner liner 10, and the through hole 211 on the cabin cover 21 is set in the corresponding position.

[0163] The wire harness fixing component 30 is fixed to the end wall 13, the front side wall 141 or the rear side wall 142, which adapts to the needs of the various orientations of the stepped space 110 in different refrigerator structures, and enhances the versatility and applicability of the technical solution.

[0164] Example 4

[0165] like Figure 9 As shown, the difference between this embodiment and embodiment 1 is that the inner liner 10 includes a side wall 14 located on the side of the stepped space 110, and the side wall 14 includes a rear side wall 142. The wire harness fixing member 30 of embodiment 4 is fixedly connected to the rear side wall 142.

[0166] Figure 9The rear side wall 142 is the rearmost wall of the inner liner 10, and the through hole 211 on the cabin cover 21 is set in the corresponding position.

[0167] In embodiments 2 to 4 above, the wire harness fixing component 30 is fixed to the end wall 13, front side wall 141 or rear side wall 142 of the inner liner 10. By adjusting the installation position of the wire harness fixing component 30, this solution can be adapted to different refrigerator 100 structural layouts and meet the needs of different positions, thereby enhancing the flexibility and versatility of the design.

[0168] Example 5

[0169] like Figure 10 As shown, the difference between this embodiment and embodiment 1 is that the connecting part 31 in this embodiment only includes a connecting wall, and the wire harness fixing member 30 of embodiment 5 can be used to combine with embodiments 2, 3 and 4 respectively.

[0170] In other words, the wire harness fastener 30 can be fixed at any position on the corner or side of the inner liner 10.

[0171] Compared with commonly used technologies, this embodiment has the following advantages:

[0172] The wiring harness 40 of the freezer 100 can extend into the stepped space 110 through the wiring hole 324 and the through hole 211 on the engine compartment cover 21. This allows the wiring harness 40 to be pre-organized and fixed before assembly, reducing the number of steps during assembly and improving production efficiency. In particular, the guide part 33 of the wiring harness fixing part 30 plays a guiding role during assembly, enabling the wiring harness fixing part 30 to quickly align with the through hole 211, reducing the difficulty of repeated manual adjustments and significantly improving assembly speed and efficiency. Furthermore, the guide part 33 defines the insertion path of the wiring harness fixing part 30, ensuring that the alignment of the wiring harness fixing part 30 with the through hole 211 is consistent each time it is assembled, enhancing standardization and consistency in the production process. In addition, the guide part 33 guides the installation of the inner liner 10 and the outer shell 50. With the guidance of the guide part 33, the installation of the inner liner 10, especially the wiring harness 40, can be guided. Therefore, the assembly process of the freezer 100 is more efficient, product quality is improved, and production and subsequent maintenance costs are effectively controlled.

[0173] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0174] The detailed descriptions listed above are merely specific descriptions of feasible implementations of this utility model, and are not intended to limit the scope of protection of this utility model. All equivalent implementations or modifications made without departing from the spirit of this utility model should be included within the scope of protection of this utility model.
