[0022] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.
[0023] The following is for reference. Figures 1-13 This application describes a refrigeration device according to an embodiment of the present application.
[0024] It should be noted that the storage device in this embodiment can be understood as a refrigeration storage device in a broad sense, including but not limited to refrigerators, freezers, display cases, beverage cabinets, wine cabinets, refrigerated display cases, and refrigerated vending machines. The storage devices have diverse structural forms and a wide range of applications.
[0025] The storage equipment includes a box and a door. The box includes an outer shell, an inner liner, and an insulation layer located between the outer shell and the inner liner. The outer shell covers the inner liner and provides protection. The insulation layer can be a foam layer, which provides insulation and cushioning. A compressor compartment is formed between the outer shell and the inner liner. The compressor compartment is used to house machines such as compressors and fan modules.
[0026] like Figure 1 , Figure 2 and Figure 5 As shown, the refrigeration equipment in the application embodiment includes a housing 1, a door 2, a front trim assembly 16, a compressor 6, and a condenser 5.
[0027] The housing 1 forms a refrigeration compartment 11, a compressor compartment 12, and a storage compartment 13. At least a portion of the compressor compartment 12 is located on the front side of the refrigeration compartment 11. A door 2 is closable and located on the housing 1, enclosing the storage compartment 13. When the door 2 is closed, the bottom of the door 2 is spaced apart from the bottom of the housing 1. A front trim assembly 16 is located on the front side of the compressor compartment 12 and below the door 2. The front trim assembly 16 includes a fan module 162 and a front trim cover 161. The front trim cover 161 forms a fan mounting cavity 1614 for installing the fan module 162. The front wall of the compressor compartment 12 is provided with a heat dissipation vent communicating with the fan mounting cavity 1614. A compressor 6 and a condenser 5 are located in the compressor compartment 12. The heat dissipation channel 51 of the condenser 5 extends in the front-rear direction.
[0028] At least a portion of the compressor compartment 12 is located in front of the refrigeration compartment 11 in the front-rear direction. In other words, at least a portion of the vertical orthographic projection of the compressor compartment 12 is located in front of the vertical orthographic projection of the refrigeration compartment 11 in the front-rear direction.
[0029] For example, the vertical orthographic projection of the compressor compartment 12 is located in front of the vertical orthographic projection of the refrigeration compartment 11 in the front-back direction; or, a portion of the vertical orthographic projection of the compressor compartment 12 is located in front of the vertical orthographic projection of the refrigeration compartment 11 in the front-back direction.
[0030] In related technologies, the compressor compartment 12 of the refrigeration equipment is usually located at the bottom of the cabinet 1 and near the rear, while the evaporator 3 is usually located at the back of the refrigeration equipment. The compressor compartment 12 and the evaporator 3 occupy the rear space of the cabinet 1, resulting in a smaller drawer depth.
[0031] In this embodiment, the refrigeration compartment 11 is located at the bottom, the evaporator 3 is located at the bottom, and the compressor compartment 12 is at least partially located in front of the refrigeration compartment 11. This reduces its occupation of the depth space of the rear storage compartment 13, thereby allowing for the design of deeper storage drawers and effectively increasing the usable internal volume of the equipment.
[0032] The box 1 includes an outer shell and an inner liner 17. The inner liner 17 forms a storage compartment 13, which is used to store items. A bottom insulation layer is provided between the refrigeration compartment 11 and the compressor compartment 12. A heat insulation component is provided between the back of the inner liner 17 and the outer shell. The thermal conductivity of the heat insulation component is lower than that of the bottom insulation layer. A heat insulation layer is provided between the side wall of the inner liner 17 and the outer shell.
[0033] Among them, the heat insulation component can be a vacuum insulation panel (VIP) or other materials with a lower thermal conductivity than the conventional polyurethane foam used in the bottom insulation layer, which can greatly improve the heat insulation performance of the rear wall of the box 1 and reduce the thickness of the back of the refrigeration equipment.
[0034] The refrigeration system mainly includes an evaporator 3 and a compressor 6. The evaporator 3 is located in the refrigeration compartment 11 and is used to absorb heat from the cabinet 1. The compressor 6 and the condenser 5 are located in the compressor compartment 12, which is located at the bottom of the inner liner 17 and at least partially located at the front of the refrigeration compartment 11.
[0035] When the door 2 is closed, the bottom of the door 2 is spaced apart from the bottom of the housing 1. In other words, when the door 2 is closed, the bottom of the door 2 is not lower than the top of the compressor compartment 12, so as to provide installation space for the front trim component 16.
[0036] The front trim component 16 is located on the front side of the compressor compartment 12. The front trim component 16 and the front side of the compressor compartment 12 form a fan mounting cavity 1614. When the fan mounting cavity 1614 is connected to the compressor compartment 12 and the door 2 is closed, it is located below the door 2.
[0037] In other words, when the door 2 is closed, the front trim assembly 16 and the door 2 have an overlapping area in their orthographic projection at the bottom of the housing 1.
[0038] The fan module 162 is installed in the fan mounting cavity 1614. The fan module 162 will accelerate the air flow speed in the compressor compartment 12. The accelerated air flow can more effectively remove the heat emitted by the condenser 5 and improve the heat dissipation efficiency.
[0039] For example, the fan module 162 draws in air from the surrounding environment, the air enters the compressor compartment 12 through the heat dissipation vents on the front wall of the compressor compartment 12, and is then accelerated by the fan and blown toward the condenser 5. Alternatively, the fan module 162 draws air out of the compressor compartment 12, thereby accelerating the airflow speed within the compressor compartment 12. The accelerated airflow can more effectively remove the heat emitted by the condenser 5.
[0040] Among them, the fan module 162 is a heat dissipation fan unit, which is used to dissipate heat from heat-generating components such as the condenser 5 and the compressor 6 inside the compressor 6.
[0041] Installing the fan module 162 in the fan mounting cavity 1614 formed in the front trim panel 161 means that the compressor compartment 12 does not need to be equipped with a cooling fan. That is, the fan module is taken out from the compressor compartment 12 and placed in the front trim component 16, which reduces the encroachment on the space inside the compressor compartment 12, thereby providing more space for the layout optimization of other core components inside the compressor compartment 12.
[0042] For example, this layout allows for a more rational arrangement of key components such as the compressor 6 and condenser 5, simplifying their wiring and reducing electromagnetic interference caused by limited space. Simultaneously, this arrangement improves airflow efficiency within the compressor compartment 12, enabling faster dissipation of heat generated during operation, thus enhancing the overall stability and reliability of the equipment and extending its lifespan. Furthermore, it allows for a reduction in the size of the compressor compartment 12, minimizing its space requirements and increasing the volume of the storage compartment 13, thereby improving the effective volumetric efficiency of the refrigeration equipment.
[0043] Among them, such as Figure 5 As shown, the heat dissipation channel 51 of the condenser 5 extends in the front-to-back direction, that is, the heat dissipation channel 51 of the condenser 5 faces the location of the fan module. The fan module can directly draw in and blow air into the heat dissipation channel 51 of the condenser 5, thereby increasing the heat dissipation effect of the condenser 5.
[0044] The condenser 5 includes an adjacent first heat dissipation surface and a second heat dissipation surface. The heat dissipation area of the first heat dissipation surface is larger than that of the second heat dissipation surface. The axial direction of the heat dissipation channel 51 of the condenser 5 is parallel to the normal of the first heat dissipation surface. The first heat dissipation surface of the condenser 5 faces the fan module, thereby increasing the heat dissipation area of the condenser 5 and improving the heat dissipation effect.
[0045] According to the refrigeration equipment provided in the embodiments of this application, on the one hand, by placing at least a portion of the compressor compartment 12 in front of the refrigeration compartment 11 in the front-rear direction, its occupation of the depth space of the rear storage compartment 13 can be reduced, thereby allowing for the design of deeper storage drawers and effectively increasing the usable volume inside the equipment; on the other hand, by removing the fan module from the compressor compartment 12 and placing it in the front trim assembly 16, the utilization of the fan module in the space inside the compressor compartment 12 is reduced, thereby providing more space for the layout optimization of other core components inside the compressor compartment 12; at the same time, the required space of the compressor compartment 12 can also be reduced, increasing the effective volume ratio of the refrigeration equipment.
[0046] The number of wind turbine units included in the wind turbine module can be determined according to the actual configuration structure. For example, the number of wind turbine units included in the wind turbine module includes at least the following two types.
[0047] Firstly, the wind turbine module consists of only one wind turbine unit.
[0048] The heat dissipation vent includes a first vent 121 and a second vent 122. One of the first vent 121 and the second vent 122 is an air inlet, and the other is an air outlet. The fan module 162 is located in front of the first vent 121 or the second vent 122 to accelerate the airflow inside the compressor chamber 12.
[0049] The front side of the compressor compartment 12 forms a first mounting cavity 16141 and a second mounting cavity 16142. A first opening 121 connects to the first mounting cavity 16141, and a second opening 122 connects to the second mounting cavity 16142. The fan unit is installed in the first mounting cavity 16141 or the second mounting cavity 16142, which can accelerate the air flow speed in the compressor compartment 12. The accelerated air flow can more effectively remove the heat emitted by the condenser 5 and improve the heat dissipation effect of the condenser 5.
[0050] Secondly, such as Figure 9 As shown, the fan module 162 includes a first fan unit and a second fan unit.
[0051] The heat dissipation vents include a first vent 121 and a second vent 122; the front trim assembly 16 also includes a front trim cover 161, the front trim cover 161 and the front side of the compressor compartment 12 form a first mounting cavity 16141 and a second mounting cavity 16142, the first vent 121 is connected to the first mounting cavity 16141, and the second vent 122 is connected to the second mounting cavity 16142; a first fan unit is disposed in the first mounting cavity 16141, and a second fan unit is disposed in the second mounting cavity 16142.
[0052] One of the first fan unit and the second fan unit is used to draw outside air into the compressor compartment 12, and the other of the first fan unit and the second fan unit is used to exhaust outside air from the compressor compartment 12, thereby forming a complete airflow cycle.
[0053] In actual use, when the equipment and the first and second fan units are running, external air can be drawn into the first mounting cavity 16141 by the first fan unit through the ventilation structure on the front cover 161, and enter the compressor compartment 12 from the first port 121. The airflow blows towards the compressor 6 and condenser 5 and other heat-generating components in the compressor compartment 12, taking away the heat they emit. The second fan unit draws the hot air in the compressor compartment 12 out of the compressor compartment 12 from the second port 122, enters the second mounting cavity 16142, and is discharged from another ventilation structure on the front cover 161, thus forming a complete airflow cycle.
[0054] The first and second fan units can work together according to the actual heat dissipation needs of the equipment. For example, when the equipment is running under high load, both fan units can run at higher speeds simultaneously to provide a larger air volume and enhance the heat dissipation effect; when the equipment is running under low load, only one fan unit can be started or the speed of both fan units can be reduced to save energy.
[0055] In this embodiment, the first mounting cavity 16141 and the second mounting cavity 16142 provide independent heat dissipation channels 51 for the first fan unit and the second fan unit, reducing mutual airflow interference between different fan units, allowing air to flow more smoothly over the heat-generating components and improving heat exchange efficiency; at the same time, if one fan unit fails, the other fan unit can still work normally and continue to provide a certain degree of heat dissipation for the equipment, ensuring the normal operation of the equipment for a certain period of time, improving the reliability and stability of the equipment, and enhancing fault tolerance.
[0056] The types of fans in the first and second fan units can be the same or different.
[0057] For example, the first fan unit is a centrifugal fan unit 1621, and the second fan unit is a cross-flow fan unit 1622; or, both the first fan unit and the second fan unit are centrifugal fan units 1621; or, both the first fan unit and the second fan unit are cross-flow fan units 1622.
[0058] In some embodiments, the fan module 162 includes a fan mounting housing and a cooling fan. The fan mounting housing covers the heat dissipation port and has a ventilation port connected to the fan mounting cavity 1614. The cooling fan is installed inside the fan mounting housing.
[0059] The cooling fan is installed inside the fan mounting housing, which can effectively reduce the vibration and noise generated during the operation of the fan, while ensuring the stability and reliability of the fan when rotating at high speed. At the same time, the fan mounting housing acts as a volute, serving as an air collection chamber, providing a stable working environment for the fan and reducing air intake turbulence.
[0060] In some embodiments, the first fan unit includes a first fan housing and a first fan. The first fan housing is covered by a first opening 121 and has a ventilation opening communicating with a first mounting cavity 16141. The first fan is mounted on the first fan housing.
[0061] The ventilation structures corresponding to the first opening 121, the vent, the first mounting cavity 16141, and the front cover 161 form airflow channels for the compressor compartment 12 to receive or release air.
[0062] In some embodiments, the second fan unit includes a second fan housing and a second fan. The second fan housing is covered by the second opening 122 and has a ventilation opening communicating with the second mounting cavity 16142. The second fan is mounted on the second fan housing.
[0063] The ventilation structures corresponding to the second opening 122, the vent, the second mounting cavity 16142, and the front cover 161 form airflow channels for the compressor compartment 12 to receive or release air.
[0064] In some embodiments, such as Figure 8and Figure 9 As shown, the first fan is a centrifugal fan, and the first inlet 121 is located on the front wall of the compressor compartment 12. The normal line of the plane where the ventilation opening of the first fan casing is located intersects the normal line of the plane where the first inlet 121 is located.
[0065] The first opening 121 faces the front of the housing 1, and the ventilation opening of the first fan housing faces a different direction than the first opening 121. For example, the ventilation opening of the first fan housing can face the left, right, upper or lower side of the housing 1.
[0066] The centrifugal fan is characterized by axial air intake and radial air exhaust. The normal line of the plane where the ventilation port of the first fan casing is located intersects with the normal line of the plane where the first opening 121 is located, which conforms to the working characteristics of the centrifugal fan.
[0067] In this embodiment, the centrifugal fan casing is designed in the form of a "right-angle turn", which allows the first fan unit itself to be installed "side-to-side", making full use of the corner space between the front wall, side wall or bottom / top plate of the front cover 161, and reducing the thickness occupied by the first fan unit in the front-to-back direction.
[0068] In some embodiments, such as Figure 8 and Figure 9 As shown, the second fan is a cross-flow fan, and the casing of the second fan is provided with ventilation openings in both the left and right directions.
[0069] Among them, the cross-flow fan is characterized by airflow entering and exiting along the axial direction (i.e., left and right direction) of the fan impeller. The second fan casing is equipped with ventilation openings in both the left and right directions, which can match the working characteristics of the cross-flow fan, increase the fan air volume, and reduce noise.
[0070] In some embodiments, such as Figure 8 and Figure 9 As shown, the first fan unit is a centrifugal fan unit 1621, and the first port 121 includes multiple heat dissipation holes distributed in a circular array. The circular array coincides with the orthographic projection of the ventilation area of the first fan unit on the front side of the housing 1.
[0071] The first opening 121 includes multiple heat dissipation holes arranged in a circular array, and the circular array coincides with the orthographic projection of the ventilation area of the centrifugal fan unit 1621 on the front side of the housing 1.
[0072] The ventilation area of the centrifugal fan unit 1621 is roughly circular. The first opening 121 is designed as multiple heat dissipation holes distributed in a circular array, which overlap with the ventilation area of the centrifugal fan unit 1621. This can enhance the air intake or blowing volume of the centrifugal fan unit 1621 into the compressor chamber 12 and improve the heat dissipation efficiency of the compressor chamber 12.
[0073] In some embodiments, such as Figure 8 and Figure 9As shown, the second fan unit is a cross-flow fan unit 1622, and the second port 122 includes multiple heat dissipation holes distributed in a rectangular array. The rectangular array coincides with the orthographic projection of the ventilation area of the second fan unit on the front side of the housing 1.
[0074] The second opening 122 includes multiple heat dissipation holes arranged in a rectangular array, and the rectangular array coincides with the orthographic projection of the ventilation area of the cross-flow fan unit 1622 on the front side of the housing 1.
[0075] The ventilation area of the cross-flow fan unit 1622 is roughly rectangular. The second outlet 122 is designed as multiple heat dissipation holes distributed in a rectangular array, which overlap with the ventilation area of the cross-flow fan unit 1622. This can enhance the air intake or blowing volume of the cross-flow fan unit 1622 into the compressor compartment 12 and improve the heat dissipation efficiency of the compressor compartment 12.
[0076] In some embodiments, such as Figure 6 and Figure 7 As shown, the front trim panel 161 includes a front trim body 1611 and an air guide structure 1612. The air guide structure 1612 protrudes from the front trim body 1611 and bends downward along the height direction. The bottom of the air guide structure 1612 is spaced apart from the front trim body 1611 to form a downward ventilation structure.
[0077] The ventilation structure is used for heat dissipation in the compressor compartment 12.
[0078] The air guide structure 1612 protrudes from the front trim body 1611 and bends downwards in the height direction. This unique shape design allows the air guide structure 1612 to effectively guide the direction of airflow. The bottom of the air guide structure 1612 is spaced apart from the front trim body 1611, forming a downward ventilation structure that provides a channel for airflow exhaust.
[0079] The air guide structure 1612 forms a downward airflow, which can prevent the airflow from blowing directly on the user's feet and also reduce the risk of the user's hands reaching into the compressor compartment 12.
[0080] In some embodiments, the air guide structure 1612 protrudes from the front trim body 1611 and bends upward in the height direction, with the top of the air guide structure 1612 spaced apart from the front trim body 1611 to form an upward ventilation structure.
[0081] The ventilation structure is used for heat dissipation in the compressor compartment 12. The air guide structure 1612 forms an upward airflow, which can also prevent the airflow from blowing directly on the user's feet and reduce the risk of the user putting their hands into the compressor compartment 12.
[0082] In some embodiments, such as Figure 6 and Figure 9As shown, the air guiding structure 1612 includes a first air guiding part and a second air guiding part. The first air guiding part is connected between the front trim body 1611 and the second air guiding part. The second air guiding part is bent downward or upward relative to the first air guiding part. The second air guiding part is spaced apart from the front trim body 1611 to form a ventilation structure.
[0083] In some embodiments, such as Figure 10 As shown, the front trim cover 161 also includes a partition plate 1615, which divides the front trim cover 161 into a first mounting cavity 16141 and a second mounting cavity 16142. Ventilation structures are provided on both sides of the partition plate 1615. The ventilation structure on one side of the partition plate 1615 is connected to the first mounting cavity 16141, and the ventilation structure on the other side of the partition plate 1615 is connected to the second mounting cavity 16142.
[0084] The partition plate 1615 can reduce air leakage between the first mounting cavity 16141 and the second mounting cavity 16142, realize directional unidirectional airflow in the compressor chamber 12, and improve the heat dissipation effect.
[0085] Ventilation structures are provided on both sides of the partition plate 1615. External air can pass through the ventilation structure on one side of the partition plate 1615, the first mounting cavity 16141, the first opening 121, the compressor chamber 12, the second opening 122, the second mounting cavity 16142, and then flow out from the ventilation structure on the other side of the partition plate 1615; or, the fan module can rotate in the opposite direction to drive the external air to flow in the opposite direction.
[0086] In some embodiments, such as Figure 1 and Figure 2 As shown, the front side of the front trim component 16 does not protrude from the front side of the door body 2 in the front-rear direction.
[0087] In other words, the front side of the front trim component 16, as projected onto the bottom of the housing 1, does not protrude in the front direction from the front side of the door 2, as projected onto the bottom of the housing 1.
[0088] In other words, the distance from the front side of the front trim component 16 to the back of the housing 1 is no greater than the distance from the front side of the door 2 to the back of the housing 1.
[0089] In this case, the front side of the front trim assembly 16 and the front side of the door 2 are aligned in the front-rear direction; or, the front side of the front trim assembly 16 does not protrude from the front side of the door 2 in the front-rear direction.
[0090] In this embodiment, the front side of the front trim component 16 does not protrude from the front side of the door body 2 in the front-back direction, which can reduce the space occupied in the front-back direction and reduce the overall size of the refrigeration equipment in the depth direction, thereby saving installation space.
[0091] In some embodiments, the distance between the front surface of the door 2 and the front surface of the front trim assembly 16 in the front-rear direction is no more than 3mm, that is, the front surface of the door 2 and the front surface of the front trim assembly 16 are basically flush in the front-rear direction, which improves the appearance of the refrigeration equipment; at the same time, it can reduce the space occupied in the front-rear direction and reduce the overall size of the refrigeration equipment in the depth direction, thereby saving installation space.
[0092] In some embodiments, such as Figure 4 and Figure 5 As shown, the front trim assembly 16 also includes a dustproof component 162, which is detachably connected to the front trim cover 161.
[0093] The dustproof component 162 can be connected to the front trim panel 161 by plug-in, snap-fit or magnetic connection, so that the dustproof component 162 can be removed from the front trim panel 161 for maintenance and replacement.
[0094] The dustproof component 162 is located behind the ventilation structure of the front cover 161 and is used for dust prevention.
[0095] In some embodiments, the dustproof component 162 is a metal plate that can help dissipate heat.
[0096] For example, the dustproof component 162 can be a stainless steel heat sink plate. The dustproof component 162 contacts the press support plate 15 and absorbs the heat in the press chamber 12 by conducting heat dissipation, thereby increasing the heat dissipation area and assisting in heat dissipation during the heat dissipation process.
[0097] In some embodiments, such as Figure 6 and Figure 7 As shown, the top of the front trim panel 161 has a mounting hole 1613, and the top of the front trim panel 161 has a forward-folding mounting flange 1621. The dustproof part 162 is inserted into the mounting hole 1613 from top to bottom until the mounting flange 1621 engages with the mounting hole 1613.
[0098] When installing the dustproof component 162 and the front trim panel 161, align the dustproof component 162 with the mounting hole 1613 and insert it vertically downwards. When the dustproof component 162 is inserted into place, its own snap-fit structure (such as a spring buckle or hook) interacts with the mounting flange 1621, ultimately achieving a snap-fit fixation. The mounting flange 1621 here serves as both the mating surface for the snap-fit and the limiting surface in the height direction.
[0099] In this embodiment, the entire installation process of the dustproof component 162 and the front cover plate 161 consists of only three actions: "alignment-insertion-clamping". No screws or auxiliary tools are required, which greatly simplifies the assembly operation on the production line, improves the assembly efficiency, and makes it easier for users to disassemble and install during later cleaning.
[0100] Meanwhile, the top-down insertion method utilizes gravity assistance, making the installation process smoother. The assembly flange 1621 provides a clear and robust edge for the snap-fit, improving snap-fit reliability and preventing it from loosening or falling off due to vibration or external force.
[0101] Meanwhile, the mounting hole 1613 and the flange provide precise circumferential positioning for the dustproof part 162, reducing its left-right or front-back swaying and preventing it from falling off along the height direction, thus improving the neatness after assembly.
[0102] Meanwhile, since the snap-fit structure is located at the top and is fitted by the mounting flange 1621, almost no fasteners, screws or other connection marks are visible when viewed from the front or bottom of the equipment, forming a hidden installation and improving the aesthetics.
[0103] When it is necessary to clean or replace the dust cover 162, usually only a certain force needs to be applied to the flange to release the latch, and the dust cover 162 can be removed. The maintenance operation is very intuitive and convenient.
[0104] In some embodiments, the top of the dust cover 162 is aligned with the top of the front trim panel 161.
[0105] In other words, the top of the dust cover 162 is aligned with the top of the front trim panel 161 in both the height and front-rear directions.
[0106] In other words, the mounting flange 1621 does not protrude from the outer surface of the front trim panel 161.
[0107] In this embodiment, the mounting flange 1621 closes the mounting hole 1613, and the dustproof part 162 is flush with the surface of the front cover plate 161 or presents a regular embedded appearance, resulting in a strong sense of unity.
[0108] In some embodiments, such as Figure 11 As shown, the housing 1 includes an inner liner 17, and the front end of the cabin cover 14 has an upwardly folded first connecting portion 141, which forms an upwardly open first connecting groove 1411. The bottom of the front end of the inner liner 17 has a downwardly folded second connecting portion 171, at least a portion of which is located within the first connecting groove 1411.
[0109] The inner liner 17 and the cabin cover 14 form an embedded structure.
[0110] The front edge of the cabin cover 14 has an upwardly folded edge, forming a first connecting portion 141. This first connecting portion 141 is further processed or shaped into a first connecting groove 1411 with an "opening upward". The cross-section of the first connecting groove 1411 is typically U-shaped, C-shaped, or L-shaped, providing containment and guiding space for subsequent docking.
[0111] The bottom edge of the front end of the inner liner 17 has a downward folded edge, forming a second connecting portion 171. This second connecting portion 171 is a mating part that mates with the first connecting portion 141.
[0112] When the inner liner 17 is assembled with the cabin cover 14, the second connecting portion 171 at the front end of the inner liner 17 is inserted into and accommodated in the first connecting groove 1411 at the front end of the cabin cover 14. Specifically, at least a portion of the second connecting portion 171 is located within the internal space of the first connecting groove 1411, forming a nested docking relationship.
[0113] During assembly, simply align the second connecting part 171 at the lower front of the inner liner 17 with the first connecting groove 1411 and place it down. This will automatically complete the precise alignment and positioning of the two parts in the front-back and left-right directions, greatly simplifying the assembly alignment process and achieving fast and accurate longitudinal and lateral positioning, thus improving assembly accuracy and efficiency.
[0114] In this embodiment, the nested groove-edge mating structure forms a mechanical interlock at the connection point, similar to a "plug-in" or "socket." This significantly enhances the connection strength between the front end of the inner liner 17 and the lower support structure (engine compartment cover 14), effectively resisting the shearing force in the front-to-back direction and the torsional force in the left-to-right direction generated during equipment handling, movement, or use. This reduces the risk of loosening or relative displacement at the connection point and enhances the rigidity and stability of the connection.
[0115] The overlapping area of the first connecting groove 1411 and the second connecting part 171 forms a regular, continuous annular or strip-shaped contact surface. This is advantageous for arranging sealing strips, applying sealant, or serving as a barrier boundary for foaming material. The nested structure itself can also, to some extent, prevent the foaming material from excessively flowing upward into the interior of the housing 1 during high-pressure foaming, ensuring the quality of the foaming process and thus providing an ideal sealing interface and foaming barrier.
[0116] In some embodiments, such as Figure 11 As shown, the second connecting portion 171 has a first clearance groove 1711 with an open front facing, and the first groove wall of the first connecting groove 1411 located on the front side is located within the first clearance groove 1711. The first clearance groove 1711 and the first groove wall of the first connecting groove 1411 on the front side form a concave-convex fit structure. The inner liner 17 has a first clearance groove 1711 with an open front on the second connecting part 171. The first clearance groove 1711 has a concave structure in cross-section.
[0117] The first connecting groove 1411 at the front end of the cabin cover 14, the first groove wall on the front side (i.e. the groove wall near the front of the equipment and facing the user), is designed in shape and size to be able to fit into and be accommodated in the first clearance groove 1711.
[0118] Therefore, the first relief groove 1711 (recess) of the second connecting part 171 and the first groove wall of the first connecting groove 1411 fit together to form a concave-convex fit structure, which reduces the height of the first connecting part 141 protruding from the second connecting part 171 in the front-back direction after the first connecting part 141 and the second connecting part 171 form a nested structure, thus improving the aesthetics.
[0119] In this embodiment, the mechanical interlocking of the protrusions and concave parts significantly enhances the connection point's resistance to shear forces in the front-to-back direction and pull-out forces in the up-and-down direction, making the connection between the upper housing 1 and the lower component more robust and stable, increasing connection reliability. Simultaneously, when the equipment door 2 is opened, the joint between the front end of the inner liner 17 and the lower component is exposed to the user's view; the convex-concave fit structure makes this joint neat, concealed, and smoothly transitioned. The design of the protrusions embedded in the concave parts avoids the uneven gaps or misalignments that may occur with simple butt joints, presenting a refined and integrated visual experience, enhancing the product's detail quality and high-end feel.
[0120] In some embodiments, such as Figure 11 As shown, the portion of the second connecting part 171 located within the first connecting groove 1411 has a first protrusion 1712, and the first protrusion 1712 is connected to the groove wall of the first connecting groove 1411.
[0121] The first protrusion 1712 can protrude forward to connect with the rearward groove wall of the first connecting groove 1411, or the first protrusion 1712 can protrude backward to connect with the first groove wall.
[0122] The second connecting portion 171 located within the first connecting groove 1411 has an integrally formed or machined protruding structure, namely the first protrusion 1712. This protrusion can be a continuous rib or spaced protrusions or bumps.
[0123] When the second connecting part 171 is inserted into the first clearance groove 1711 and fully in place, the first protrusion 1712 will be tightly connected to or in contact with the groove wall of the first connecting groove 1411.
[0124] The first protrusion 1712 can be connected to the groove wall of the first connecting groove 1411 in the following ways.
[0125] For example, the first protrusion 1712 can form an interference fit with the groove wall of the first connecting groove 1411: the first protrusion 1712 is slightly higher than the design gap in the free state, and generates a continuous pressing force with the groove wall of the first connecting groove 1411 by relying on its elastic deformation.
[0126] For example, the snap-fit connection: the first protrusion 1712 is designed with a barb or elastic claw to engage with the recess or latch corresponding to the groove wall of the first connecting groove 1411.
[0127] Adhesion or welding: After the first protrusion 1712 comes into contact with the groove wall of the first connecting groove 1411, it is fixed by applying glue or partial welding.
[0128] In this embodiment, the portion of the second connecting part 171 located within the first connecting groove 1411 transforms from a "passive" insertion structure into an "active" support point or limiting point. The first protrusion 1712 abuts against or engages with the groove wall of the first connecting groove 1411 from the inside, effectively reducing the elastic deformation or loosening of the groove wall of the first connecting groove 1411 under stress (such as shear force or vibration), and increasing the reliability of the nested groove-edge mating structure.
[0129] Meanwhile, with the addition of the first protrusion 1712 as an internal locking structure, the force attempting to pull the second connecting part 171 out of the first clearance groove 1711 will be directly blocked by the mechanical obstruction of the first protrusion 1712. This significantly improves the resistance of the connection point to pull-out force in the vertical separation direction, increasing the reliability of the nested groove-edge mating structure.
[0130] Meanwhile, the interference or snap-fit design of the first protrusion 1712 can precisely eliminate the tiny gaps caused by manufacturing tolerances at the interface between the concave and convex parts, achieving a tight fit without shaking or abnormal noise, thus improving the overall texture and structural quality of the product.
[0131] In some embodiments, such as Figure 12 As shown, a plurality of second protrusions 1713 are formed at the top of the first protrusion 1712 at intervals, and the protrusion direction of the second protrusions 1713 is opposite to the protrusion direction of the first protrusion 1712.
[0132] The top of the first protrusion 1712 can be the outer or inner surface of the highest point, and the top of the first protrusion 1712 is formed with a plurality of second protrusions 1713 spaced apart.
[0133] The first protrusion 1712 is a "main beam" that protrudes in the front-to-back direction from the portion of the second connecting portion 171 located within the first connecting groove 1411. The second protrusion 1713 is a "small bump" or "short rib" that protrudes in the opposite direction (towards the inward indentation of the first protrusion 1712) from the top of this "main beam". The second protrusion 1713 protrudes in the opposite direction to the first protrusion 1712, forming a variation with a cross-section similar to a "T" or "I".
[0134] In this embodiment, when the groove wall of the first connecting groove 1411 presses against the first protrusion 1712, the reverse second protrusion 1713 can act as a micro-damping unit, which can generate small elastic deformation when compressed, absorb vibration energy, and reduce transmission; at the same time, it transforms a single line or surface contact into multiple discrete high-point contacts, forming multi-point contact, which helps to optimize the contact stress distribution, reduce excessive stress concentration, and increase the structural strength of the first protrusion 1712.
[0135] In some embodiments, such as Figure 13 As shown, the portion of the second connecting portion 171 located within the first connecting groove 1411 is formed with a plurality of spaced-apart third protrusions 1714. The protrusion direction of the third protrusions 1714 is the same as the protrusion direction of the first protrusions 1712, and the third protrusions 1714 are connected to the first protrusions 1712.
[0136] The second connecting portion 171 is located within the first connecting groove 1411. In addition to the first protrusion 1712, it also has a plurality of spaced-apart third protrusions 1714. The protrusion direction of the third protrusions 1714 is the same as that of the first protrusions 1712, and the third protrusions 1714 are connected to the first protrusions 1712.
[0137] The first protrusion 1712 acts as the "main ridge" of the portion of the second connecting part 171 located within the first connecting groove 1411, while the plurality of third protrusions 1714 are "auxiliary ribs" or "support columns" laterally connected to the "main ridge". Together, they constitute a reinforcing rib network of the second connecting part 171.
[0138] In this embodiment, the third protrusion 1714 acts as a "buttress" to support the first protrusion 1712 from the side, which greatly improves the ability of the first protrusion 1712 to resist the lateral pressure (bending stress) from the groove wall of the first connecting groove 1411 and reduces its root breakage or excessive deformation.
[0139] Meanwhile, the pressure from the first protrusion 1712 can be more widely distributed to the entire area of the second connection 171 through the connected third protrusion 1714, reducing load concentration and improving the overall load-bearing capacity and deformation resistance of the second connection 171.
[0140] Meanwhile, the regular reinforcing rib network is conducive to the flow of plastic melt and the maintenance of pressure during injection molding, reducing shrinkage marks, ensuring stable molding quality of the structural part, and improving injection molding processability.
[0141] This embodiment employs a multi-level (opposite / same direction) reinforcing rib design for the first protrusion 1712, the second protrusion 1713, and the third protrusion 1714, upgrading the simple protrusion structure into a structure with directional mechanical properties. This enhances the reliability of the connection between the first connecting part 141 and the second connecting part 171, and optimizes vibration damping and stress distribution. In some embodiments, the housing 1 includes an inner liner 17, a cabin cover 14, and a press support plate 15. The cabin cover 14 and the press support plate 15 together form the press compartment 12, and the inner liner 17 forms a storage compartment 13 and a refrigeration compartment 11.
[0142] The distance L1 of the compressor support plate 15 from the ground satisfies: 0≤L1≤10mm, that is, the compressor support plate 15 is basically in contact with the ground with a small gap. For embedded installation scenarios, the rollers at the bottom of the refrigeration equipment can be eliminated. In scenarios where there is no heat dissipation requirement at the bottom of the refrigeration equipment, the gap between the compressor support plate 15 and the ground can be 0mm.
[0143] For example, when L1=0mm, the compressor support plate 15 is in contact with the ground, which can increase the effective volume of the refrigeration equipment at the same height.
[0144] For example, L1 can be 3mm, 5mm or 10mm.
[0145] Among them, such as Figure 4 As shown, the distance L2 from the compressor 6 to the engine compartment cover 14 satisfies: L2≥10mm, reducing the risk of damage to the compressor 6 caused by deformation of the engine compartment cover 14 and the compressor support plate 15.
[0146] For example, L2 can be 11mm, 13mm, 15mm or larger.
[0147] For example, L2 = 10 mm to account for the 5 mm foaming deformation of the cabin cover 14 and the 5 mm upward deformation of the compressor support plate 15 during the drop test.
[0148] The minimum distance L3 from the highest point of the cabin cover 14 to the inner liner 17 satisfies: L3≥20mm, so as to form a bottom insulation layer. The bottom insulation layer can be a foam material or a vacuum insulation board.
[0149] For example, L3 can be 20mm, 25mm or larger.
[0150] Among them, such as Figure 3 As shown, the lowest point at the bottom of the inner liner 17 forms a drain outlet, and the minimum distance L4 from the lowest point at the bottom of the inner liner 17 to the lowest point at the bottom of the engine compartment cover 14 satisfies: 41mm≤L4≤51mm.
[0151] The lowest point of the bottom of the inner liner 17 forms a drain outlet, and the minimum distance from the drain outlet to the lowest point of the engine compartment cover 14 is L4. For example, L4 can be 41mm, 45mm, 50mm or 51mm.
[0152] The drain pipe is tilted at 7° with reference to the height of evaporating dish 4, and the diameter of the drain pipe is 10mm.
[0153] The housing 1 includes an evaporating dish 4, which is located in the compressor chamber 12. The height L5 of the evaporating dish 4 satisfies the following condition: 25mm≤L5≤35mm.
[0154] For example, L5 can be 25mm, 30mm or 35mm.
[0155] By placing the evaporating dish 4 within the aforementioned range, its volume can be increased to 2L, thus meeting the usage requirements.
[0156] In this embodiment, based on the above dimensions, the compressor chamber 12 occupies a smaller space, and the inner liner 17 can obtain a larger volume.
[0157] In some embodiments, such as Figure 3 As shown, the refrigeration chamber 11 includes a first sub-chamber 111 and a second sub-chamber 112 distributed along the front and rear. The evaporator 3 is disposed in the second sub-chamber 112. The second sub-chamber 112 is connected to the return air vent of the refrigeration chamber 11 through the first sub-chamber 111. The vertical orthographic projection of the first sub-chamber 111 is located within the vertical orthographic projection of the refrigeration chamber 11, and the vertical orthographic projection of the second sub-chamber 112 is located behind the vertical orthographic projection of the refrigeration chamber 11.
[0158] The second sub-compartment 112 is connected to the return air vent of the refrigeration compartment 11 through the first sub-compartment 111, so that the return air flow path is: return air vent, first sub-compartment 111 and second sub-compartment 112 in sequence.
[0159] The vertical projection of the first sub-cabin 111 lies entirely within the vertical projection area of the compressor compartment 12. This layout makes full use of the space above the compressor compartment 12.
[0160] The vertical projection of the second sub-compartment 112 is located behind the vertical projection of the compressor compartment 12. This completely separates the core heat exchange area from the high-temperature compressor 6 area in space.
[0161] In this embodiment, the first sub-compartment 111 serves as a buffer and pre-treatment channel before the airflow enters the evaporator 3. Its layout above the compressor compartment 12 allows for the use of the low-temperature sidewall of the compressor compartment 12 (or through thermal insulation design) to pre-cool the intake air, achieving airflow pre-cooling and thermal isolation. At the same time, it physically isolates the direct radiative heating of the intake air by the high temperature of the compressor 6, reducing the heat load of the evaporator 3.
[0162] Meanwhile, by placing the air intake channel (first sub-compartment 111) above the compressor compartment 12 and the core heat exchange area (second sub-compartment 112) behind it, a three-dimensional staggered arrangement of the refrigeration flow channel and the heat dissipation area of the compressor 6 is achieved. This not only makes efficient use of space, but also achieves active isolation between hot and cold zones through structural design, improving the overall energy efficiency of the system and optimizing space utilization and thermal management.
[0163] Meanwhile, the airflow, after being guided and buffered by the first sub-compartment 111, can enter the evaporator 3 of the second sub-compartment 112 more smoothly and evenly, improving the uniformity of airflow, which helps to improve the heat exchange efficiency and service life of the evaporator 3 and reduce the problem of local frost caused by uneven airflow.
[0164] In some embodiments, the refrigeration compartment 11 further includes a third sub-compartment located between the first sub-compartment 111 and the second sub-compartment 112, at least a portion of the vertical orthographic projection of the first sub-compartment 111 is located within the vertical orthographic projection of the refrigeration compartment 11, and the flow cross-sectional area of the third sub-compartment gradually increases from front to back.
[0165] The return airflow path is as follows: return air inlet, first sub-compartment 111, third sub-compartment, and second sub-compartment 112. The third sub-compartment is located between the first sub-compartment 111 and the second sub-compartment 112, serving as an airflow transition and distribution area.
[0166] The flow cross-sectional area of the third sub-compartment is designed to gradually increase from front to back, forming a gradually expanding flow channel.
[0167] In this embodiment, the first sub-compartment 111 serves as the first chamber through which airflow enters, and can initially stabilize and distribute the air drawn in from the return air vent. The gradually expanding design of the third sub-compartment can effectively reduce the airflow velocity and make the airflow more uniform and stable before entering the second sub-compartment 112 where the evaporator 3 is located, thereby significantly improving the overall heat exchange efficiency of the evaporator 3 and avoiding local overcooling or frosting.
[0168] In this embodiment, the gradually expanding third sub-compartment causes the airflow velocity from the first sub-compartment 111 to gradually decrease and the static pressure to increase. This helps the airflow achieve a more uniform velocity and pressure distribution across the flow cross-section before entering the heat exchange area of the evaporator 3 in the second sub-compartment 112, creating ideal conditions for efficient and uniform heat exchange in the evaporator 3, and effectively reducing the risk of dead zones and localized frost formation.
[0169] Meanwhile, the gradually expanding structure can smoothly guide the airflow direction, reduce unstable flows such as eddies and turbulence caused by abrupt changes in the flow cross section, optimize the flow field stability, thereby reducing airflow noise and energy loss, and improving the working efficiency and stability of the fan system.
[0170] Meanwhile, the layout of the first sub-compartment 111, located within the compressor compartment 12 projection, is maintained, continuing to utilize idle space and provide thermal insulation. The newly added third sub-compartment, serving as a functional flow channel transition area, further improves the rationality of the airflow path from the intake to the core heat exchange area, strengthens spatial coupling and thermal insulation, and enables more precise management of hot and cold zones.
[0171] Meanwhile, by implementing a refined design of the airflow path of "pre-treatment (first sub-compartment 111) → uniform flow transition (third sub-compartment) → core heat exchange (second sub-compartment 112)," the aerodynamic performance inside the refrigeration compartment 11 is systematically improved, thereby directly enhancing the heat exchange efficiency of the evaporator 3 and the overall energy efficiency ratio of the refrigeration system, while also strengthening the long-term reliability of the system operation.
