[0046] Figure 1 It is a structural schematic diagram of refrigeration equipment in some embodiments of the present utility model. Figure 2 yes Figure 1 Schematic diagram of the internal structure.

[0047] like Figure 1 and Figure 2 As shown, the refrigeration device provided in an embodiment of the present invention may include a housing 1. The housing 1 may be configured as an external housing for the refrigeration device. The housing 1 may typically have a hollow rectangular structure. It should be noted that in other embodiments, the external shape of the housing 1 may be designed as desired and is not limited here. The interior of the housing 1 may be used to provide installation space.

[0048] In some embodiments, a refrigeration compartment 20 may be formed in the box body 1. The refrigeration compartment 20 may be used as an independent storage space, and may be used as a refrigerator, a freezer, etc., to meet different storage needs such as refrigeration and freezing according to different types of stored items.

[0049] In some embodiments, a plurality of refrigeration compartments 20 may be provided in the cabinet 1. The plurality of refrigeration compartments 20 may be arranged in the cabinet 1 in a manner of being divided vertically or horizontally.

[0050] like Figure 1 and Figure 2 As shown, in some embodiments, a door 11 may be provided on the front side of the refrigerator body 1. The door 11 may be used to open and close the refrigeration compartment 20. The door 11 may be connected to the refrigerator body 1 via a hinge, so that the door 11 of the refrigerator can rotate about the axis of the hinge to open and close the door 11, thereby opening and closing the corresponding refrigeration compartment 20.

[0051] In some embodiments, multiple doors 11 can be provided. Multiple doors 11 can be provided in a one-to-one correspondence with multiple refrigeration compartments 20. It should be noted that in other embodiments, multiple doors 11 can also open and close a refrigeration compartment 20 at the same time.

[0052] like Figure 1 and Figure 2 As shown, in some embodiments, a cabinet 1 may be provided with a cabinet liner 2. A refrigeration compartment 20 may be formed within the cabinet liner 2. Multiple cabinet liner 2 may be provided within the cabinet 1. The multiple cabinet liner 2 may be arranged in the cabinet 1 in a vertically separated or horizontally separated manner. Each cabinet liner 2 may form one or more refrigeration compartments 20.

[0053] Figure 3 yes Figure 2 Front view of . Figure 4 yes Figure 3 Middle AA section view.

[0054] like Figure 3 and Figure 4 As shown, in some embodiments, a refrigeration system may be provided in the cabinet 1. The refrigeration system may be provided inside the cabinet 1. The refrigeration system may be used to provide cold air inside the refrigerator to maintain a low temperature environment in each refrigeration compartment 20.

[0055] In some embodiments, the refrigeration system may include a compressor 3. The compressor 3 may compress the refrigerant into high-temperature and high-pressure refrigerant vapor.

[0056] In some embodiments, the refrigeration system may include a condenser (not shown). The compressor 3 may deliver the compressed refrigerant to the condenser. The condenser may condense the high-temperature and high-pressure refrigerant vapor.

[0057] In some embodiments, the refrigeration system may include a throttling device (not shown). The condenser may deliver the condensed refrigerant to the throttling device. The throttling device may be a capillary tube. The throttling device may be used to throttle and reduce the pressure of the refrigerant.

[0058] In some embodiments, the refrigeration system may include an evaporator 4. The throttling device may deliver the throttled and depressurized refrigerant to the evaporator 4. The evaporator 4 may be used to evaporate and boil the refrigerant vapor so as to absorb heat from the surrounding medium.

[0059] In some embodiments, the compressor 3 , the condenser, the throttling device, and the evaporator 4 may be sequentially connected to form a refrigeration circuit. Refrigerant may circulate in the refrigeration circuit to achieve cooling of the interior of the cabinet 1 .

[0060] like Figure 4 As shown, in some embodiments, a compressor compartment 12 may be provided within the cabinet 1. The compressor compartment 12 may be provided in the bottom area of ​​the cabinet 1. The compressor compartment 12 may be located at the rear lower portion of the refrigeration compartment 20. The compressor compartment 12 may be located at the rear lower portion of the cabinet 2. The compressor 3, condenser, etc. may be provided within the compressor compartment 12. When the compressor 3 and condenser are operating, they will each dissipate heat into the compressor compartment 12, and dissipate heat to the outside of the cabinet 1 through the compressor compartment 12.

[0061] It should be noted that, in some other embodiments, the press chamber 12 may also be arranged at other positions in the box body 1 .

[0062] like Figure 3 and Figure 4 As shown, in some embodiments, the evaporator 4 can be arranged inside the box liner 2. The evaporator 4 can be arranged on the rear side wall of the refrigeration compartment 20. When the evaporator 4 is working, the evaporator 4 can exchange heat with the surrounding air, so that the evaporator 4 absorbs heat from the air, and then directly cools the air inside the box liner 2, thereby achieving refrigeration in the refrigeration compartment 20. Specifically, for some small refrigerators, beverage cabinets and other refrigeration equipment with smaller volumes, the evaporator 4 can be directly arranged inside the liner. In this way, the refrigeration compartment 20 inside the box liner 2 can be directly cooled by the evaporator 4 to meet the refrigeration needs. In addition, by arranging the evaporator 4 on the inner side wall of the liner, the internal space occupied by the refrigeration compartment 20 can be reduced.

[0063] In some embodiments, the bottom of the liner 2 may be provided with a stepped portion 21. The compressor compartment 12 may be located in the area below the stepped portion 21. The evaporator 4 may be located on the rear sidewall above the stepped portion 21. This allows for a rational layout of the interior space of the refrigeration unit 1, reducing the overall size of the refrigeration equipment.

[0064] like Figure 4As shown, in some embodiments, a shelf 22 may be provided on the front side of the top surface of the step portion 21. The shelf 22 may be located at the same height as the top surface of the step portion 21. In this way, the shelf 22 can separate the space within the refrigeration compartment 20 into upper and lower storage spaces. The upper storage space may be located in the space above the top surface of the step portion 21 and the top surface of the shelf 22. The lower storage space may be located in the space above the front side of the step portion 21 and the bottom surface of the shelf 22.

[0065] In some embodiments, the shelf 22 can be made of, for example, a wire rack structure. The wire rack structure is relatively thin. The wire rack structure can have multiple hollow holes (not shown). In this way, the shelf 22 formed by the wire rack structure can not only meet the structural strength requirements of the shelf 22, but also reduce the thickness of the shelf 22, thereby reducing the space occupied by the internal space of the refrigeration compartment 20. At the same time, the evaporator 4 can cool the air in the upper storage space, and the cold air in the upper storage space can flow into the lower storage space through the hollow holes of the wire rack structure, thereby cooling the air in the lower storage space.

[0066] It should be noted that, in some other embodiments, the shelf 22 may also be made of other materials with a porous structure.

[0067] Figure 5 yes Figure 3 Schematic diagram of the structure of the evaporator 4 and the limiter 6.

[0068] like Figure 4 and Figure 5 As shown, in some embodiments, the evaporator 4 can be a blown evaporator 4. The blown evaporator 4 can have a plate-like structure and can be arranged upright on the rear wall of the refrigeration liner 2. Thus, the plate-like structure of the blown evaporator 4 allows the blown evaporator 4 to be directly fixed to the rear wall of the refrigeration liner 2, reducing the space occupied by the evaporator 4 within the refrigeration compartment 20.

[0069] In some embodiments, the inflation evaporator 4 may include an evaporator plate 41 and a refrigerant channel 42 formed within the evaporator plate 41. The refrigerant channel 42 is used to circulate the refrigerant. The evaporator plate 41 may be made of copper or aluminum sheet material, processed to a plate structure of a specific shape and size. The evaporator plate 41 may be arranged upright on the rear side wall of the interior of the chamber 2. The refrigerant channel 42 may be formed within the evaporator plate 41 by a inflation machine under the action of high-pressure gas.

[0070] In some embodiments, the inflation evaporator 4 may include a refrigerant inlet pipe (not shown). The refrigerant inlet pipe may be located outside the evaporator plate 41. The refrigerant inlet pipe may be a capillary tube. The refrigerant channel 42 within the evaporator plate 41 may have an inlet. One end of the refrigerant inlet pipe may be connected to the inlet of the refrigerant channel 42. The other end of the refrigerant inlet pipe may be connected to the condenser via a throttling device. In this manner, the refrigerant, after being throttled and reduced in pressure by the throttling device, can be transported through the refrigerant inlet pipe to the refrigerant channel 42, where it then absorbs heat from the surrounding air through the evaporator plate 41, thereby cooling the refrigeration compartment 20.

[0071] It should be noted that, in some embodiments, the refrigerant inlet pipe and the throttling device may both adopt a capillary structure. In this case, the refrigerant inlet pipe may serve as part of the throttling device, that is, the end of the throttling device close to the evaporation plate 41 serves as the refrigerant inlet pipe.

[0072] In some embodiments, the inflation evaporator 4 may include a refrigerant output pipe 43. The refrigerant output pipe 43 may be disposed outside the evaporator plate 41. The refrigerant channel 42 within the evaporator plate 41 may have an outlet. One end of the refrigerant output pipe 43 may be connected to the outlet of the refrigerant channel 42. The other end of the refrigerant output pipe 43 may be connected to the return air port of the compressor 3. In this manner, refrigerant vapor evaporated from the refrigerant channel 42 can flow out through the refrigerant output pipe 43 and return to the compressor 3 through the refrigerant output pipe 43.

[0073] like Figure 3 and Figure 4 As shown, in some embodiments, the refrigeration device may include a control box 5. The control box 5 may be located on the inner wall of the refrigeration compartment 20. The control box 5 may be connected to the compressor 3 for signal communication. The control box 5 may be used to control the power of the compressor 3, thereby adjusting the temperature of the evaporator 4. In this way, the user can independently adjust and control the storage temperature within the refrigeration compartment 20 through the control box 5.

[0074] In some embodiments, the control box 5 may be disposed on the right side wall of the refrigeration compartment 20. The control box 5 may be disposed on the front side of the evaporator 4.

[0075] It should be noted that, in some other embodiments, the control box 5 may also be disposed on the left side wall or other side walls of the refrigeration compartment 20 .

[0076] like Figure 3 and Figure 4As shown, in some embodiments, the control box 5 may be provided with an adjustment knob 51. The adjustment knob 51 is rotatably connected to the control box 5. The outer wall of the control box 5 may be provided with multiple temperature settings. When the adjustment knob 51 is rotated to a corresponding temperature setting, the power level of the compressor 3 is adjusted accordingly, thereby adjusting the storage temperature within the refrigeration compartment 20 to the corresponding level. In this way, the user can easily rotate the adjustment knob 51 to the corresponding temperature setting to independently adjust and control the desired storage temperature within the refrigeration compartment 20.

[0077] Figure 6 yes Figure 5 Schematic diagram of the structure from another perspective.

[0078] like Figure 4 and Figure 6 As shown, in some embodiments, the refrigeration device may include a limiter 6. The limiter 6 may be installed on the evaporator 4. The limiter 6 may be protruding from the front side wall of the evaporator 4 so that the front side wall of the limiter 6 and the front side wall of the evaporator 4 are arranged in a front-to-back spacing. In this way, when a can or bottle such as a beverage can is placed in the refrigeration compartment 20, the can or bottle such as a beverage can will be against the front side wall of the limiter 6 and maintain a certain distance from the evaporator 4, thereby effectively avoiding direct contact between the can or bottle such as the beverage can and the surface of the evaporator 4. The temperature of the surface of the evaporator 4 is relatively low, and the limiter 6 can prevent the beverage can from directly contacting the low temperature of the surface of the evaporator 4, thereby avoiding the problem of can explosion, thereby improving the protection and reliability of the evaporator 4.

[0079] In some embodiments, the stopper 6 can be an elongated strip extending laterally along the width of the evaporator 4. The length of the stopper 6 can be the same as the width of the evaporator 4 in the left-right direction of the refrigeration compartment 20. This laterally extending structure of the stopper 6 can enhance the surface protection provided by the stopper 6 to the evaporator 4. When a beverage can is placed from any area within the refrigeration compartment 20 to the back side of the refrigeration compartment 20, the beverage can abuts against the stopper 6, ensuring that the beverage can does not come into direct contact with the surface of the evaporator 4.

[0080] like Figure 4 and Figure 6 As shown, in some embodiments, the stopper 6 can be installed at the bottom edge of the evaporator 4. In this way, when a beverage can is placed on the back side of the refrigeration compartment 20, the bottom of the beverage can can contact the stopper 6, preventing the beverage can from directly contacting the surface of the evaporator 4. At the same time, the evaporator 4 can exchange heat with the air in the refrigeration compartment 20 from the area above the stopper 6, reducing the impact of the stopper 6 on the evaporator 4's cooling efficiency.

[0081] It should be noted that, in some other embodiments, the limiting member 6 may also be installed at other areas of the front side wall of the evaporator 4 .

[0082] In some embodiments, the stopper 6 can be made of plastic. Thus, the plastic stopper 6 can reduce the low temperature of the evaporator 4 from being transferred to the stopper 6. This prevents the temperature of the stopper 6 from being too low when the beverage can contacts the stopper 6.

[0083] It should be noted that, in some other embodiments, the limiting member 6 may also be made of other materials with low thermal conductivity.

[0084] In some embodiments, the evaporator 4 may be provided with a heating element (not shown in the figure). The heating element may be laid on the surface of the evaporation plate 41 of the evaporator 4. The heating element can be used to heat the evaporator 4. When the evaporator 4 is performing cooling work, the evaporator 4 exchanges heat with the air in the refrigeration compartment 20, and the moisture in the air will gradually condense on the surface of the evaporator 4, causing frost to form on the surface of the evaporator 4. In this way, when the frost on the surface of the evaporator 4 is thick, the operation of the refrigeration system can be stopped, and the evaporator 4 can be heated by the heating element to melt the frost on the surface of the evaporator 4 to form defrost water, thereby achieving the defrosting function of the evaporator 4. In this way, it is also possible to prevent the frost on the front wall of the evaporator 4 from being too thick, causing the frost on the front wall of the evaporator 4 to directly contact the beverage cans in the refrigeration compartment 20.

[0085] Figure 7 yes Figure 6 A decomposition diagram of . Figure 8 yes Figure 7 Schematic diagram of the structure of the middle limit member 6.

[0086] like Figure 4 、 Figure 7 and Figure 8 As shown, in some embodiments, the retaining member 6 may be provided with a water receiving groove 60 with an upward opening. The water receiving groove 60 may be an elongated strip extending transversely along the length of the retaining member 6, i.e., the extending direction of the water receiving groove 60 may coincide with the extending direction of the retaining member 6. The water receiving groove 60 may be located below the front side wall of the retaining member 6. In this way, when the evaporator 4 is defrosting, the defrosted water on the front side wall of the evaporator 4 can flow downward into the water receiving groove 60, where it can be collected and discharged by the water receiving groove 60 on the retaining member 6.

[0087] In some embodiments, the length of the water receiving groove 60 can be consistent with the length of the stopper 6. The length of the water receiving groove 60 can be consistent with the width of the evaporator 4. In this way, the defrost water in each area on the front side wall of the evaporator 4 can flow downward into the water receiving groove 60.

[0088] like Figure 4 and Figure 6As shown, in some embodiments, a drainage groove 23 may be provided at the bottom area of ​​the rear end of the refrigeration compartment 20. A drainage port 231 may be provided on the bottom surface of the drainage groove 23. A stopper 6 may be provided above the drainage groove 23. This allows liquid within the water receiving trough 60 to flow downward into the drainage groove 23. The liquid within the drainage groove 23 can then be discharged from the refrigeration compartment 20 through the drainage port 231 and then discharged from the cabinet 2.

[0089] In some embodiments, the drain groove 23 can be a long strip structure and extend laterally along the width of the liner 2. The drain groove 23 can extend laterally left and right along the bottom area of ​​the rear wall of the liner 2. The drain groove 23 can extend laterally along the length of the stopper 6. The drain groove 23 can be located below the evaporator 4 and the stopper 6. In this way, the defrost water on the rear side wall of the evaporator 4 can flow directly downward into the drain groove 23, while the defrost water on the front side wall of the evaporator 4 can first flow downward into the water receiving groove 60 of the stopper 6 and then flow downward into the drain groove 23.

[0090] In some embodiments, the drain port 231 may be located at the lowest point of the drain tank 23 , so that all the liquid in the drain tank 23 can be drained to the outside of the tank 2 through the drain port 231 .

[0091] In some embodiments, the drainage groove 23 may be provided on the top surface of the step portion 21. The drainage groove 23 may be provided at the rear edge of the top surface of the step portion 21.

[0092] like Figure 4 As shown, in some embodiments, a drain pipe 24 can be provided on the outside of the tank 2. The upper end of the drain pipe 24 can be connected to a drain port 231. The lower end of the drain pipe 24 can extend into the interior of the press chamber 12. In this way, the liquid in the drain tank 23 can be discharged into the press chamber 12 through the drain port 231 and the drain pipe 24.

[0093] In some embodiments, a water receiving pan 13 may be provided in the press chamber 12. The lower end of the drain pipe 24 may extend to the water receiving pan 13. In this way, condensed water or defrost water in the drain trough 23 can be drained into the water receiving pan 13 through the drain pipe 24 and collected in the water receiving pan 13, or evaporated in the water receiving pan 13 and released into the air in the press chamber 12.

[0094] like Figure 6 and Figure 8As shown, in some embodiments, the bottom of the retaining member 6 may be provided with a leaking hole 601. The leaking hole 601 may be provided on the bottom surface of the water receiving trough 60. The leaking hole 601 may be connected to the water receiving trough 60. The leaking hole 601 may be located above the drainage trough 23. Thus, the leaking hole 601 connects to the water receiving trough 60. With the leaking hole 601 located above the drainage trough 23, liquid in the water receiving trough 60 can flow downward through the leaking hole 601 into the drainage trough 23.

[0095] It should be noted that, in some other embodiments, the leakage hole 601 may also be provided on the sidewall of the water receiving trough 60. Alternatively, in some other embodiments, the leakage hole 601 may not be provided on the stopper 6. In this case, the liquid in the water receiving trough 60 can flow downward into the drainage trough 23 through both ends of the water receiving trough 60.

[0096] In some embodiments, the bottom surface of the water receiving trough 60 may be provided with a plurality of drainage holes 601. The plurality of drainage holes 601 may be sequentially spaced and arranged along the extension direction of the water receiving trough 60. This allows the liquid in the water receiving trough 60 to simultaneously flow downward into the drainage trough 23 through the plurality of drainage holes 601, thereby improving the drainage efficiency of the liquid in the water receiving trough 60. It should be noted that the number and position of the drainage holes 601 can be adjusted as needed and are not limited here.

[0097] Figure 9 yes Figure 8 A top view of . Figure 10 yes Figure 9 Middle BB section view.

[0098] like Figure 6 、 Figure 9 and Figure 10 As shown, in some embodiments, the limiting member 6 may include a limiting rear wall 61. The limiting rear wall 61 may be located at the rear side of the limiting member 6. The limiting rear wall 61 may extend along the length direction of the limiting member 6. The limiting rear wall 61 may extend along the width direction of the evaporator 4. The limiting rear wall 61 may be provided below the bottom side of the evaporator 4. In this way, the extending structure of the limiting rear wall 61 cooperates with the bottom side edge of the evaporator 4, so that the bottom side edge of the evaporation plate 41 of the evaporator 4 can be connected to the limiting rear wall 61 up and down, so that the limiting member 6 can be installed and fixed at the bottom side edge of the evaporator 4.

[0099] In some embodiments, the limiting member 6 may include a limiting front wall 62. The limiting front wall 62 may be located in front of the limiting member 6. The limiting front wall 62 may be arranged at intervals in front of the limiting rear wall 61. The limiting front wall 62 may be extended along the length direction of the limiting member 6. The limiting front wall 62 may be extended along the width direction of the evaporator 4. In this way, when the limiting member 6 is fixed to the bottom edge of the evaporator 4 through the limiting rear wall 61, the limiting front wall 62 may be protected at intervals in front of the evaporator 4, and the limiting front wall 62 may be arranged to extend laterally in front of the evaporator 4. In this way, when a can or bottle such as a beverage can is placed in the refrigeration compartment 20, the bottom of the beverage can may abut against the limiting front wall 62 to prevent it from directly contacting the front side wall of the evaporator 4.

[0100] In some embodiments, the limiting member 6 may include a limiting bottom wall 63. The limiting bottom wall 63 may be located at the bottom of the limiting member 6. The limiting bottom wall 63 may be arranged between the limiting front wall 62 and the limiting rear wall 61. The limiting bottom wall 63 may extend along the length direction of the limiting member 6. The limiting bottom wall 63 may extend along the width direction of the evaporator 4. The front side of the limiting bottom wall 63 may be connected to the bottom end of the limiting front wall 62. The rear side of the limiting bottom wall 63 may be connected to the bottom end of the limiting rear wall 61. In this way, the limiting front wall 62 and the limiting rear wall 61 can be connected by the limiting bottom wall 63. When the bottom of the beverage can abuts against the limiting front wall 62, the limiting front wall 62 can transfer the abutting force to the limiting rear wall 61 through the limiting bottom wall 63, and then transfer it to the evaporator 4 and the rear wall of the tank 2, so that the limiting front wall 62 can stably and reliably protect the front side of the evaporator 4.

[0101] In some embodiments, the water receiving groove 60 can be formed between the limiting bottom wall 63, the limiting front wall 62, and the limiting rear wall 61. Thus, by forming the water receiving groove 60 between the limiting bottom wall 63, the limiting front wall 62, and the limiting rear wall 61, the defrost water on the front side wall of the evaporator 4 can flow downward into the water receiving groove 60, and the defrost water can be collected and discharged through the water receiving groove 60.

[0102] like Figure 4 and Figure 10 As shown, in some embodiments, the top height of the limiting front wall 62 can be higher than the top height of the limiting rear wall 61. Thus, when the limiting member 6 is secured to the bottom edge of the evaporator 4 via the limiting rear wall 61, the limiting front wall 62 can cover the front side of the bottom edge of the evaporator 4, thereby increasing the protective area and isolation effect of the evaporator 4. In some embodiments, the limiting member 6 can be manufactured using an extrusion molding process. Thus, the limiting front wall 62, the limiting rear wall 61, and the limiting bottom wall 63 can be integrally formed through extrusion molding, thereby improving the production efficiency of the limiting member 6.

[0103] like Figure 10As shown, in some embodiments, a water leakage hole 601 can be formed on the limiting bottom wall 63. The limiting bottom wall 63 can be located above the drainage groove 23. The water leakage hole 601 can be located on the bottom surface of the water receiving groove 60. In this way, the water leakage hole 601 can connect to the water receiving groove 60 above the limiting bottom wall 63, thereby draining the liquid in the water receiving groove 60 into the drainage groove 23 below it.

[0104] In some embodiments, the limiting bottom wall 63 may include a first bottom wall 631 and a second bottom wall 632 connected at an angle. The rear side of the first bottom wall 631 may be connected to the bottom end of the limiting rear wall 61. The first bottom wall 631 may be arranged to be tilted downward toward the direction close to the limiting front wall 62. The front side of the first bottom wall 631 may be connected to the rear side of the second bottom wall 632. The front side of the second bottom wall 632 may be connected to the bottom end of the limiting front wall 62. The second bottom wall 632 may be arranged to be tilted downward toward the direction close to the limiting rear wall 61. The water leakage hole 601 may be provided at the connection between the first bottom wall 631 and the second bottom wall 632. In this way, the angle structure of the first bottom wall 631 and the second bottom wall 632, combined with the inclined arrangement of the first bottom wall 631 and the second bottom wall 632, can make the connection between the first bottom wall 631 and the second bottom wall 632 located at the lowest point of the limiting bottom wall 63, and thus make the leakage hole 601 located at the lowest point of the water receiving trough 60, so that all the liquid in the water receiving trough 60 can be discharged from the leakage hole 601 to the drainage trough 23 below it.

[0105] like Figure 10 As shown, in some embodiments, a mounting groove 611 with an opening facing upward may be provided on the limiting rear wall 61. The extension direction of the mounting groove 611 may be consistent with the extension direction of the limiting rear wall 61. The mounting groove 611 may be extended along the length direction of the limiting member 6. The mounting groove 611 may be extended along the width direction of the evaporator 4. The bottom side edge of the evaporator 4 may be plugged and fixed in the mounting groove 611. In this way, through the structure of the mounting groove 611, the bottom side edge of the evaporator 4 and the limiting rear wall 61 can be relatively fixed by plugging and installing, so that the limiting rear wall 61 and the entire limiting member 6 are firmly installed at the bottom side edge of the evaporator 4, thereby improving the connection stability between the bottom side edge of the evaporator 4 and the limiting member 6, and also facilitating the improvement of the installation efficiency of the limiting member 6. In addition, when the bottom of the beverage can abuts against the limiting front wall 62, the limiting rear wall 61 can stably and reliably transmit the abutting force to the evaporator 4 through the mounting groove 611, so that the limiting front wall 62 can be more stably and reliably protected on the front side of the evaporator 4.

[0106] like Figure 8 and Figure 10As shown, in some embodiments, a screw hole (not shown in the figure) may be provided on the limiting rear wall 61. The screw hole may penetrate the limiting rear wall 61 in the front-to-back direction. The screw hole may be connected to the mounting groove 611. A fixing hole may be provided on the bottom side edge of the evaporator 4. When the bottom side edge of the evaporator 4 is aligned and inserted into the mounting groove 611, the fixing hole may be connected to the screw hole. The limiting rear wall 61 can be fixed to the bottom side edge of the evaporator 4 by a fixing member (such as a screw) passing through the fixing hole and the screw hole.

[0107] It should be noted that in some other embodiments, the screw hole may only penetrate one side of the wall of the mounting slot 611. For example, the screw hole may only penetrate the front wall of the mounting slot 611, and the fixing member may be fixedly disposed in both the fixing hole and the front wall of the mounting slot 611. Alternatively, the screw hole may only penetrate the rear wall of the mounting slot 611, and the fixing member may be fixedly disposed in both the fixing hole and the rear wall of the mounting slot 611.

[0108] like Figure 8 and Figure 10 As shown, in some embodiments, transversely extending ribs 612 may be protruding from the sidewalls of the mounting groove 611. The extending direction of the ribs 612 may be consistent with the extending direction of the mounting groove 611. Thus, when the bottom edge of the evaporator 4 is inserted into the mounting groove 611, the ribs 612 can abut against the bottom edge of the evaporator 4, clamping the bottom edge of the evaporator 4 in the mounting groove 611, thereby facilitating the installation and fixation of the stopper 6.

[0109] In some embodiments, multiple ribs 612 may be provided, and the multiple ribs 612 may be arranged parallel and spaced apart on the sidewalls of the mounting slot 611. In this way, the multiple ribs 612 can abut against the bottom edge of the evaporator 4, thereby improving the stability of the bottom edge of the evaporator 4 when inserted into the mounting slot 611.

[0110] In some embodiments, multiple ribs 612 may be provided, and the multiple ribs 612 may be divided into two groups. The two groups of ribs 612 may be respectively provided on the front and rear walls of the mounting slot 611. The two groups of ribs 612 may be arranged in a one-to-one correspondence. When the bottom edge of the evaporator 4 is inserted into the mounting slot 611, the bottom edge of the evaporator 4 may be clamped between the two groups of ribs 612, thereby improving the stability of the bottom edge of the evaporator 4 inserted into the mounting slot 611.

[0111] Figure 11 yes Figure 6 Schematic diagram of the structure from another perspective.

[0112] like Figure 4 and Figure 11As shown, in some embodiments, a mounting member 25 may be provided on the rear sidewall of the interior chamber 2. A mounting hole 411 may be provided on the evaporator plate 41 of the evaporator 4. The mounting member 25 may extend into the mounting hole 411. When the evaporator 4 is installed in the interior chamber 2, the evaporator 4 may be mounted on the mounting member 25 through the mounting hole 411 and thus secured to the rear sidewall.

[0113] In some embodiments, the hanging member 25 can be detachably fixed to the rear side wall of the box 2. For example, the hanging member 25 can be fixed to the rear side wall of the box 2 by screw thread connection.

[0114] It should be noted that, in some other embodiments, the hanging component 25 may also be integrally formed on the rear side wall of the box 2 .

[0115] Figure 12 yes Figure 3 Schematic diagram of the structure with the evaporator 4 and the limiter 6 removed.

[0116] like Figure 4 、 Figure 11 and Figure 12 As shown, in some embodiments, a first boss 26 may be provided on the rear side wall inside the liner 2. The first boss 26 may be protruding from the rear side wall inside the liner 2. The mounting member 25 may be detachably fixed to the first boss 26. In this way, when the evaporator 4 is mounted and fixed on the mounting member 25, the back surface of the evaporator 4 may abut against the front end surface of the first boss 26, so that the back surface of the evaporator 4 and the rear side wall inside the liner 2 can be spaced apart, so that the back surface of the evaporator 4 can contact and exchange heat with the air in the spaced apart area, thereby improving the cooling efficiency of the air in the refrigeration compartment 20.

[0117] In some embodiments, there may be multiple first bosses 26. There may be multiple hanging members 25. One hanging member 25 is correspondingly fixed on one first boss 26, so that multiple hanging members 25 can be installed and fixed on multiple first bosses 26 respectively. Accordingly, multiple hanging holes 411 can be opened on the evaporator 4. The aperture of the hanging hole 411 can be larger than the outer diameter of the hanging member 25. In this way, the evaporator 4 can be correspondingly hung on multiple hanging members 25 through multiple hanging holes 411. By supporting the evaporator 4 simultaneously with multiple hanging members 25, the gravity borne by each hanging member 25 can be reduced, and the stability of supporting and fixing the evaporator 4 can be improved.

[0118] like Figure 4 、 Figure 11 and Figure 12As shown, in some embodiments, a second boss 27 may be provided on the rear side wall inside the box 2. The second boss 27 may be protruding from the rear side wall inside the box 2. A positioning groove 271 may be provided on the front side wall of the second boss 27. A positioning column 412 extending rearward may be provided on the back side of the evaporator 4. In this way, through the cooperation between the positioning groove 271 and the positioning column 412, when the evaporator 4 is hung on the hanging member 25 through the hanging hole 411, the positioning column 412 may be arranged relative to the positioning groove 271 of the second boss 27, so that the positioning column 412 can be inserted and positioned in the positioning groove 271, and the rear side wall of the evaporator 4 can be against the front side wall of the second boss 27, which can keep the back of the evaporator 4 and the rear wall of the box 2 spaced apart and improve the stability of the evaporator 4 on the rear wall of the box 2.

[0119] In some embodiments, multiple second bosses 27 may be provided. Multiple second bosses 27 may be spaced apart on the rear wall of the interior of the casing 2 . Multiple second bosses 27 may form multiple positioning grooves 271 . Accordingly, multiple positioning posts 412 may be provided on the evaporator 4 . Thus, when the evaporator 4 is mounted on the mounting member 25 , the multiple positioning posts 412 may be positioned in different positioning grooves 271 . By simultaneously limiting the position of the evaporator 4 with multiple positioning posts 412 , the stability of the evaporator 4 may be improved.

[0120] In some embodiments, the plurality of first bosses 26 may include at least two first bosses 26. The at least two first bosses 26 may be arranged in a transversely spaced arrangement. At least two hanging members 25 may be fixed respectively on the two first bosses 26 arranged in a transversely spaced arrangement. Accordingly, two hanging holes 411 arranged in a transversely spaced arrangement may be provided on the evaporator 4. In this way, by arranging the two first bosses 26 in a transversely spaced arrangement, the two hanging members 25 may be at the same height, thereby facilitating the evaporator 4 to be hung on the two hanging members 25 respectively through the two transversely spaced hanging holes 411, thereby improving the hanging efficiency of the evaporator 4 and improving the stability of the fixation of the evaporator 4.

[0121] In some embodiments, the plurality of second bosses 27 may include at least two second bosses 27. The at least two second bosses 27 may be arranged laterally spaced apart and spaced below the two first bosses 26. Accordingly, the evaporator 4 may be provided with two laterally spaced positioning posts 412. Thus, by arranging the two second bosses 27 laterally spaced apart, the two positioning grooves 271 are positioned at the same height, thereby facilitating the positioning of the evaporator 4 within the upper positioning grooves 271 of the two second bosses 27 via the two laterally spaced positioning posts 412, thereby improving the positioning efficiency of the evaporator 4 and enhancing the stability of the evaporator 4.

[0122] It should be noted that, in some other embodiments, the number of the first boss 26 and the hanging member 25, the second boss 27 and the positioning column 412 can be adjusted accordingly as needed, and there is no limitation here.
