[0037] Please refer to Figures 1 to 9 The refrigeration appliance 1 includes a heat-insulating housing 11. The housing 11 surrounds at least one storage chamber 12 for storing items to be cooled / frozen. The housing 11 may include a main body 10 and a door (not shown) for closing the storage chamber 12.

[0038] The housing 11 includes a heat-insulating wall 13 surrounding the storage chamber 12. The heat-insulating wall 13 has a recess 16 on an inner wall facing the storage chamber 12.

[0039] In an exemplary embodiment, the insulating wall 13 includes an inner container 14 facing the storage chamber 12 , an outer shell 15 spaced apart from the inner container 14 , and an insulating medium (not shown) between the inner container 14 and the outer shell 15 . A sink 16 is formed in the inner container 14 .

[0040] The liner 14 can be made, for example, by a vacuum forming process. The heat insulating medium can include at least one of polyurethane foam, vacuum insulation material, or other types of heat insulating media.

[0041] In an exemplary embodiment, the sink 16 may extend along the height direction H of the storage chamber 16. The sink 16 is located on the side wall 121 of the storage chamber 12. It should be understood that in alternative embodiments, the sink 16 may also be located on other walls of the storage chamber 12, or on the inner wall of the door facing the storage chamber 12.

[0042] The sink 16 includes a bottom wall 161 facing the opening of the sink 16 , an upper wall 162 connected to the bottom wall 161 , a lower wall 163 , and a pair of side walls 164 .

[0043] The bottom groove wall 161 , the upper groove wall 162 , the lower groove wall 163 and the side groove wall 164 may be connected and transitioned by arcs.

[0044] The sink 16 is used to install the display unit 2. The display unit 2 is used to display information of the refrigeration appliance 1 and receive user input.

[0045] The display unit 2 includes a receiving box 3 received in the sink 16 , electronic components 4 received in the receiving box 3 , and a display panel 5 enclosing the receiving box 3 .

[0046] like Figure 3 and Figure 4 As shown, the receiving box 3 includes a bottom box wall 31 adjacent to the bottom groove wall 161 of the sink 16, an upper box wall 32 adjacent to the upper groove wall 162, a lower box wall 33 adjacent to the lower groove wall 163, and a pair of side box walls 34 adjacent to the corresponding side groove walls 164. The bottom box wall 31, the upper box wall 32, the lower box wall 33 and the side box walls 34 together define a receiving space 30 open to the storage chamber 12.

[0047] The receiving space 30 enclosed by the display panel 5 can be isolated from the rest of the sink 16 , so that even if liquid enters the sink 16 , the possibility of the liquid entering the receiving space 30 and contacting the electronic component 4 can be significantly reduced.

[0048] When the accommodating box 3 is installed in the sink 16 , the depth direction of the accommodating box 3 is parallel to the depth direction D of the sink 16 .

[0049] The receiving box 3 is fixed in the sink 16. In one embodiment, please combine Figure 2 refer to Figure 5 、 Figure 6 、 Figure 8 and Figure 9The bottom groove wall 161 has a plurality of through holes 1611 , and the accommodating box 3 is fixed to the insulation wall 13 by the fixing portion 35 extending through the through holes 1611 and extending into between the inner liner 14 and the outer shell 15 .

[0050] Each fixing portion 35 includes a resilient clip 351. The resilient clip 351 has a downwardly inclined clip 352, and the clip 352 forms an acute angle with the bottom box wall 31. The edge of the through hole 1611 is inserted into the resilient clip 351, specifically, the edge of the through hole 1611 is clamped between the clip 352 and the outer surface of the bottom box wall 31.

[0051] The fixing portion 35 further includes a guide portion 353 located between the clip 352 and the outer surface of the bottom box wall 31. The guide portion 353 connects the clip 352 and the bottom box wall 31 and can be substantially perpendicular to the bottom groove wall 161. The guide portion 161 is narrower than the clip 3512 to appropriately enhance the strength of the clip 352 while still maintaining its elasticity.

[0052] Through hole 1611 includes a through hole 1612 that allows clip 352 to pass through, and a limiting hole 1613 that is connected to through hole 1612 but is smaller than through hole 1612, preventing clip 352 from passing through. The width of limiting hole 1613 can be adapted to the width of guide portion 353 to allow guide portion 353 to enter and slide within limiting hole 1613 while being constrained by limiting hole 1613.

[0053] During assembly, the container 3 is assembled to the inner container 14 from the storage chamber 12. First, align each elastic clip 351 of the container 3 with the corresponding through hole 1612 so that the clip 352 and the guide portion 353 pass through the bottom groove wall 161 from the inner container 14. Figure 10 As shown, at this time, there is a large distance between the bottom of the accommodating box 3 and the lower groove wall 163 of the sink 16.

[0054] Then, the container 3 is pushed downward, and the elastic clip 351 moves downward so that the edge of the through hole 161 is clamped between the clip 352 and the bottom box wall 31, so that the container 3 is suspended on the inner container 14. In particular, the lower edge of the through hole 1612 is clamped between the clip 352 and the bottom box wall 31. Figure 11 As shown, after the receiving box 3 reaches the assembly position, there is an obvious distance between the upper portion of the receiving box 3 and the upper groove wall 162 of the sink 16.

[0055] During the sliding process, the guide portion 353 enters the limiting hole 1613, and the movement of the accommodating box 3 relative to the bottom groove wall 16 can be guided to be located in the fixing hole 1613, which can at least partially block the limiting hole 1613 and reduce the difficulty of preventing bubble leakage.

[0056] The receiving box 3 may further include a leakage-proof rib 354 corresponding to the through hole 1612 . The leakage-proof rib 354 extends into the through hole 1612 and is in close contact with the edge of the through hole 1612 , thereby preventing the insulation medium from leaking from the through hole 1612 .

[0057] The bottom wall 161 may also include a first wire hole 166. Accordingly, the bottom wall 31 of the container 3 has a second wire hole 39 corresponding to the wire hole 166. Electrical wires (not shown) can extend from between the inner container 14 and the outer shell 15 through the first wire hole 166 into the container 3 to connect to the electrical module 4.

[0058] The receiving box 3 is fixed to the inner liner 13 before the foaming process of the insulation wall 13 , so that the insulation medium, especially the insulation foam, can be combined with the receiving box 3 after the foaming process, and the receiving box 3 can be fixed to the insulation wall 13 very stably.

[0059] The receiving box 3 is long and narrow. Figure 3 and Figure 4 As shown, the side box wall 34 of the receiving box 3 has a plurality of elastic structures 341 spaced apart in the length direction of the receiving box 3. The elastic structures 341 abut against the inner surface of the side groove wall 164 of the sink 16 and deform, thereby preventing the receiving box 3 from shaking in the width direction W of the sink 16.

[0060] The elastic structure 341 is arranged along the opening edge of the receiving box 3 , so that the receiving box 3 is fixed at the bottom and the opening end of the receiving box 3 is tightly limited, so that the receiving box 3 can be stably fixed to the inner container 14 .

[0061] The outer surface of the elastic structure 341 facing the sink 16 is in an arc shape that bulges toward the side groove wall 164 of the sink 16 . The elastic structure 341 is elastic and facilitates the sliding of the accommodating box 3 relative to the sink 16 .

[0062] In one embodiment, the elastic structure 341 includes an arc wall 342 and a hollow portion 343 between the arc wall 342 and the inner surface of the side box wall 341. The end of the hollow portion 343 is exposed to the end surface 37 of the accommodating box 3 located at the side groove wall 164, which is conducive to the deformation of the arc wall 342 when it is squeezed.

[0063] like Figure 8 and Figure 9 As shown, the bottom of the storage box 3 is fixed to the inner container 13 and the end surface 37 of the storage box 3 facing the storage chamber 12 is completely located in the sink 16.

[0064] In one embodiment, along the depth direction D of the sink 16, the end surface 37 is close to the opening of the sink 16 but still spaced apart from the edge of the opening of the sink 16. When the display panel 5 covers the receiving box 3, the inner surface of the display panel 5 contacts the end surface 37 of the receiving box 3. Thus, along the depth direction D of the sink 16, the display panel 5 is at least partially located within the sink 16.

[0065] In one embodiment, the outer surface of the display panel 5 and the opening edge of the deep groove 16 may be substantially flush or slightly lower than the opening edge of the deep groove 16 and completely sunken into the deep groove 16 .

[0066] The electronic components 54 are housed in the housing space 30. The outer side of the display panel 5 is exposed to the storage chamber 12. The user can see the information displayed by the display unit 2 on the display panel 5 and / or operate the display unit 2 on the display panel 5.

[0067] In an exemplary embodiment, the electronic component 54 includes at least one circuit board 41 , a light source (not shown) integrated on the circuit board, and a touch sensing device 42 .

[0068] The display panel 5 may have a mounting portion 51 on its inner side, and an electronic component 54 may be mounted on the mounting portion 51. The mounting portion 51 includes a substantially rectangular mounting frame 52, and the electronic component 54 is located within the mounting frame 51. The electronic component 54 and the display panel 5 may be pre-assembled to form a pre-assembled unit 21.

[0069] The display panel 5 is secured to the receiving box 3. In one embodiment, the display panel 5 has a plurality of spaced-apart hooks 55 on the inner side facing the receiving box 3. The hooks 55 engage the receiving box 3 within the receiving space 30. When the display panel 5 is installed in the receiving box 3, the inner surface of the display panel 5 and the end surface 37 of the receiving box 3 are in close contact. Along the depth direction D of the recess 16, the connection seam 36 between the display panel 5 and the receiving box 3 is close to the opening of the recess 16.

[0070] The hook 55 engages with the inner side of the peripheral wall of the storage box 3. In one embodiment, the side box wall 34 of the storage box 3 has a plurality of slots 344, and the hook 55 extends into the receiving space 30 along the side box wall 34 and engages with the corresponding slots 344. In this way, the relative position of the display panel 5 and the storage box 3 can be precisely located. Correspondingly, the position of the display panel 5 relative to the sink 16 can also be precisely located. Even if the display panel 5 does not cover the edge of the sink 16, the relative position of the display panel 5 and the edge of the sink 16 is more controllable.

[0071] Due to the precise positioning of the display panel 5 and the receiving box 3, even if the projection of the display panel 5 along the depth direction D of the sink 16 is completely located within the projection of the opening of the sink 16, the display panel 5 is sunken into the sink 16 or the outer surface of the display panel 5 is basically flush with the opening edge of the sink 16, the gap between the display panel 5 and the inner liner 13 can also be well controlled.

[0072] When the display panel 5 is connected to the receiving box 3 and the receiving space 30 is closed, the electronic component 4 is located in the receiving space 30 covered by the display panel 5 in the sink 16. This helps to reduce the probability of foreign matter such as liquid entering the receiving space 30 and contacting the electronic component 54.

[0073] In some adverse conditions, such as condensation on the inner wall of the storage chamber 12 , the user wiping the display panel 5 or the periphery of the display panel 5 with an undone rag, or even in some tests, liquid may enter the sink 16 through the gap between the display panel 5 and the sink 16 , which may cause damage to the electronic components 54 .

[0074] To further improve the safety and reliability of the refrigeration appliance 1, a drainage channel 17 is disposed within the sink 16, isolated from the receiving space 30 and connected to the storage chamber 12. This allows liquid that has entered the sink 16 to be quickly drained out of the sink 16 along the drainage channel 17, which is isolated from the receiving space 30. The drainage channel 17 is located between the receiving box 3 and the sink 16 to prevent liquid from contacting the electronic components 4 within the enclosed receiving space 30.

[0075] The drainage channel 17 may include a first channel 171 located between the bottom box wall 31 of the receiving box 3 and the bottom groove wall 161 of the sink 16. The first channel 171 extends from the upper end to the lower end of the receiving box 3 along the bottom box wall 31 of the receiving box 3.

[0076] The drainage channel 17 may further include a second channel 172 located between the side channel wall 34 of the receiving box 3 and the side channel wall 164 of the sink 16. The second channel 172 extends from the upper end to the lower end of the receiving box 3 along the side channel wall 34 of the receiving box 3.

[0077] Liquid flowing down the first channel 171 and the second channel 172 can enter the third channel 173 located between the lower tank wall 33 of the receiving box 3 and the lower tank wall 163 of the sink 16. The third channel 173 extends along the lower box wall 33 of the receiving box 3 from the bottom end of the receiving box 3 near the bottom box wall 161 to the open end of the receiving box 3.

[0078] The third channel 173 is in communication with the storage chamber 12 , so that the liquid can flow out of the sink 16 and return to the storage chamber 12 .

[0079] In one embodiment, at least a portion of the drainage channel 17 between the receiving box 3 and the inner wall of the sink 16 may be formed by protrusions distributed at intervals on the outer side of the receiving box 3 .

[0080] Specifically, the outer side of the bottom box wall 31 of the accommodating box 3 has a first protrusion 31a, which abuts against the inner surface of the bottom groove wall 161, so that a first channel 171 extending along the bottom box wall 31 is formed between the bottom box wall 31 and the bottom groove wall 161.

[0081] In one embodiment, the side box wall 34 of the accommodating box 3 has a second protrusion 34a protruding toward the side groove wall 164, and the second protrusion 34a abuts against the inner surface of the side groove wall 164, so that a second channel 172 extending along the side box wall 34 is formed between the side box wall 34 and the side groove wall 164.

[0082] The outer side of the lower box wall 33 of the accommodating box 3 has a third protrusion 33 a. When the accommodating box 3 is installed in the sink 16 , the third protrusion 33 a abuts against the lower groove wall 163 of the sink 16 , thereby forming a third channel 173 between the lower box wall 33 and the lower groove wall 163 .

[0083] The third protrusion 33a extends along the depth direction of the accommodating box 3. In one embodiment, the end of the third protrusion 33a facing the corresponding side groove wall 164 is inclined relative to the corresponding side groove wall 164, so that a portion of the third protrusion 33a can abut against the side groove wall 164 while a gap exists between the third protrusion 33a and the side groove wall 164, thereby forming a third channel 173 extending along the side groove wall 164. In another embodiment, the third protrusion 33a can be arranged along only a portion of the depth of the side box wall 34, thereby facilitating the formation of the third channel 173 between the side box wall 34 and the side groove wall 164.

[0084] The first protrusion 31a, the second protrusion 34a and the third protrusion 33a can be in point contact, line contact or narrow surface contact with the inner wall of the groove 16. In this way, even if the inner wall of the groove 16 is uneven when the inner liner 13 is formed, the accommodating box 3 and the groove 16 can be positioned relatively accurately. In addition, this also facilitates the assembly of the accommodating box 3 to the inner liner 14, especially facilitates pushing the accommodating box 3 to the final installation position.

[0085] Along the depth direction D of the sink 16, the display panel 5 and the receiving box 3 enclose the receiving space 30 near the opening of the sink 16. The first channel 171 is arranged along the bottom wall 161 of the sink 16, and the second channel 172 is arranged along the side wall 164 of the sink 16.

[0086] Furthermore, if Figure 7 and Figure 8As shown, the display unit 2 includes a liquid blocking structure 53 , which is located in the sink 16 and outside the receiving box 3 . The liquid blocking structure 53 covers the connection seam 36 between the receiving box 3 and the display panel 5 from above.

[0087] Specifically, the liquid blocking structure 53 is located between the upper box wall 32 of the receiving box 3 and the upper groove wall 162 of the sink 16. The liquid blocking structure 53 protrudes from the inner side of the display panel 5 facing the sink 16 and extends toward the bottom groove wall 161.

[0088] The liquid blocking structure 53 extends along the depth direction D of the sink 16 to a position closer to the bottom box wall 31 of the receiving box 3 than the connection seam 36 between the receiving box 3 and the display panel 5 .

[0089] In this way, liquid entering the trough 16 through the gap between the display panel 5 and the opening edge of the trough 16 can avoid the connecting seam 36 between the receiving box 3 and the display panel 5 and be directed along the first channel 171 along the rear of the receiving box 3 and / or the second channels 172 arranged along the sides of the receiving box 3. Even if no additional sealing device (such as a sealing strip) is provided between the receiving box 3 and the display panel 5, since liquid entering the trough 16 can be prevented from flowing toward the connecting seam 36, the possibility of liquid entering the receiving box 3 and contacting the electrical module 4 can be reduced.

[0090] The liquid blocking structure 53 includes a tab 531 that protrudes from the inner side of the display panel 5 facing the sink 16 and extends toward the bottom wall 161 of the sink 16. The tab 531 is integrally formed with the display panel 5, so that there is no gap between the tab 531 and the inner surface of the display panel 5, and liquid cannot pass between the tab 531 and the inner surface of the display panel 5.

[0091] The tab 531 may extend horizontally or be tilted downward at a predetermined angle along the depth direction D of the trough 16 . When liquid falls from above, the liquid is received by the tab 531 and flows around the tab 531 and then flows to the drainage channel 17 .

[0092] There is a distance between the end of the liquid blocking structure 53 and the bottom wall 161 of the trough 16 , and the distance is greater than the depth of the drainage channel 17 along the depth direction D of the trough 16 .

[0093] In one embodiment, the upper wall 162 and bottom wall 161 of the sink 16, the upper wall 32 of the receiving box 3, and the upper portion of the display panel 5 together define a cavity 165 isolated from the receiving space 30. The liquid retaining structure 53 is located within the cavity 165. The drainage channel 17 is located downstream of the cavity 165 and communicates with the cavity 165.

[0094] The liquid blocking structure 53 in the cavity 165 is located above the upper box wall 32 of the accommodating box 3 and is spaced apart from the latter in the vertical direction. The liquid blocking structure 53 is located below the upper tank wall 162 of the sink 16 and is spaced apart from the latter in the vertical direction.

[0095] When liquid enters the trough 16 from above, it enters the cavity 165 isolated from the receiving space 30. The liquid can then fall in an orderly manner onto the liquid retaining structure 53, which is vertically spaced apart from the upper edge of the display panel 5. In extreme cases, if there is a large amount of liquid, the liquid can still be discharged in an orderly manner without entering the receiving box 3 due to the presence of the larger cavity 165 above the drainage channel 17 and the liquid retaining structure 53 located within the cavity 165.

[0096] The vertical distance between the liquid retaining structure 53 and the upper tank wall 162 is smaller than the vertical distance between the liquid retaining structure 53 and the upper box wall 32. Thus, the water entering the cavity 165 can be guided to the drainage channel 17 in a more orderly manner.

[0097] The display panel 5 includes a support 54 extending from the inner side of the display panel 5 toward the bottom groove wall 161. The support 54 abuts against the bottom groove wall 51 within the cavity 165. If a user operates the display panel 5, the portion of the display panel 5 corresponding to the cavity 165 can be supported to avoid significant deformation when being operated (e.g., pressed).

[0098] The above solution effectively prevents foreign substances, such as liquids or gas-liquid mixtures, from entering the storage box 3 through the gap between the display panel 5 and the storage box 3. To further enhance safety and reliability, the display unit 2 includes a sealing structure 6 located between the storage box 3 and the display panel 5. This sealing structure 6 further prevents, for example, moisture from entering the storage box 3 through the connecting seam 36 between the storage box 3 and the display panel 5. The sealing structure 6 includes a sealing ring 61 arranged along the opening of the storage box 3 and squeezed between the storage box 3 and the display panel 5.

[0099] like Figure 3 、 Figure 4 、 Figure 8 and Figure 9 As shown, the receiving box 3 includes a first step portion 38 located within the receiving space 30 and arranged along the opening of the receiving box 3. The first step portion 38 is spaced apart from the end surface 37 in the depth direction of the receiving box 3 and forms a step surface on the inner side of the peripheral wall of the receiving box 3 facing the opening of the receiving box 3. The display panel 5 has a rib 56 located within the receiving space 30 and resting on the first step portion 38.

[0100] There is a gap between the rib 56 and the inner surface of the display panel 5, and the sealing strip 61 is located in a space surrounded by the inner surface of the display panel 5, the rib 56, the mounting portion 51, and the inner surfaces of the upper box wall 32, the lower box wall 33 and the side box wall 34 of the accommodating box 3 and is squeezed.

[0101] The liquid blocking structure 53 and the cavity 165 are located above the sealing structure 6 and overlap with the sealing structure 6. The liquid blocking structure 53 extends to a position closer to the bottom wall 161 of the sink 16 than the sealing structure 6.

[0102] In the embodiment of the present invention, the electronic components of the display unit can be arranged in the sink in a manner of being isolated from the liquid entering the sink, thereby improving the safety and reliability of the refrigeration appliance.

[0103] In the embodiment of the present invention, the liquid entering the sink can be reliably guided to flow and be discharged while avoiding the connection seam between the display panel and the receiving box, further reducing the possibility of contact between the liquid and the electronic components.

[0104] In the embodiment of the present invention, the display panel can be accurately fixed to the containing box, and the relative relationship between the display panel and the inner wall of the heat-insulating wall can be more freely selected as needed.

[0105] Combine Figures 1 to 11 The various embodiments of the individual components of the invention can be combined with each other in any given manner to achieve the advantages of the present invention. In addition, the present invention is not limited to the embodiments shown, and other means outside the means shown can generally be used as long as these means can achieve the same effect.
