[0001] This invention relates to the field of home appliance technology, and in particular to an installation structure for a door display screen and a home appliance door. Background Technology

[0002] Home appliances are necessities for people's lives, and the appliance door is one of the important components, serving to insulate or keep the appliance warm between its interior and exterior. However, the function of the appliance door extends beyond this; it can also provide users with other forms of enjoyment, such as adding a display screen to offer a diverse range of smart experiences. Currently, the installation of display screens on appliance doors typically uses pre-embedded boxes or brackets, resulting in a simplistic installation structure. Summary of the Invention

[0003] To achieve the above objectives, the present invention is implemented through the following technical solutions.

[0004] This invention provides an installation structure for a door-mounted display screen, comprising:

[0005] The door panel separates the door body into two areas for the display screen and foam layer to be installed separately.

[0006] At least two mounting brackets are used to secure the top and bottom of the display screen, respectively.

[0007] The two extrusion strips are fixed to the door frame of the door body; the two extrusion strips fix the two sides of the fixing frame respectively to restrict the movement of the two fixing frames relative to the door panel, so as to install the display screen on the front of the door panel.

[0008] Preferably, the two sides of the first fixing frame extend toward the display screen to form two first limiting parts, which are used to abut against the two sides of the top of the display screen respectively;

[0009] And / or, the two sides of the second fixing bracket extend toward the display screen to form two second limiting parts, which are used to abut against the two sides of the top of the display screen respectively.

[0010] Preferably, the side extrusion strip is snapped onto the door frame on the outside.

[0011] Preferably, the inner side of the side extrusion strip is snapped into one side of the fixing frame.

[0012] Preferably, it also includes a support member for supporting the bottom of the display screen.

[0013] Preferably, the support member is provided with a second support portion for supporting the side extrusion strip.

[0014] Preferably, the support member is provided with a plurality of fourth snap-fit ​​parts for snapping into the bottom of the door panel.

[0015] Preferably, the support member is provided with a first fixing part for fixing the lamp panel, so that the light emitted by the lamp panel shines downward from the side end of the glass panel to form ambient light around the glass panel.

[0016] Preferably, the support member has at least two mounting surfaces for attaching the exterior finish of the door body; wherein the two mounting surfaces are staggered in height to support the two panels and form openings at the ends of the two panels.

[0017] Preferably, the support member is provided with a ventilation structure, and the ventilation structure and the opening together form an air intake passage for heat dissipation of the display screen.

[0018] The second objective of this invention is to provide a door body for a household appliance, comprising:

[0019] Display screen;

[0020] The mounting structure for the door display screen described above is used to mount the display screen.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] This invention provides an installation structure for a door display screen. By setting a pre-embedded door panel to separate the display screen from the foam layer, the assembly of the display screen is not affected by the foam layer. A split-type fixing frame structure replaces the traditional entire frame support structure. When the length of the display screen changes, only the distance between the two fixing frames located at the top and bottom of the display screen needs to be changed, without altering the structure of these two fixing frames, thus reducing processing costs. At least two fixing frames secure the top and bottom of the display screen, thereby restricting the movement of the display screen relative to the two fixing frames. Extruded strips on both sides further secure the two fixing frames, restricting their movement relative to the door panel, thus enabling the display screen to be installed on the front of the door panel. The installation structure itself is simple and easy to assemble. Furthermore, when the length of the display screen or the door body changes, only the lengths of the side extruded strips and the door panel need to be changed to match, while the fixing frame structure remains unchanged. When the width of the display screen changes, the side extruded strips do not need to be changed; only the dimensions of the fixing structures securing the top and bottom of the display screen need to be changed. When the width of the door body changes while the display screen size remains unchanged, the assembly structure between the side extruded strips and the door frame can be adjusted. This reduces the processing costs associated with adjusting the display screen size or the door body size.

[0051] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0052] Example 1

[0053] This invention provides an installation structure for a door-mounted display screen, such as... Figure 1 As shown, it includes the mounting structure body, which includes:

[0054] The door panel 120 separates the door body 101 into two areas for the display screen 210 and the foam layer to be respectively configured.

[0055] At least two mounting brackets are used to secure the top and bottom of the display screen 210, respectively.

[0056] The two extrusion strips 233 are fixed to the door frame 110 of the door body 101; the two extrusion strips 233 respectively fix the two sides of the fixing frame to restrict the movement of the two fixing frames relative to the door panel 120, so as to install the display screen 210 on the front of the door panel 120.

[0057] Specifically, to endow the door body 101 with both intelligent display and thermal insulation functions, the door body 101 has two independent spaces in the front and rear directions, separated by a pre-embedded door panel 120. One space is equipped with a bracket 230 to fix the display screen 210, and the other space is used to install the foam layer. The door body 101 includes a foamed door assembly 100 and a display screen assembly 200. The display screen assembly 200 is located on the front of the foamed door assembly 100 to endow the door body 101 with both intelligent display and thermal insulation functions. The door body 101 separates the display screen 210 from the foam layer by setting the pre-embedded door panel 120, so that the assembly of the display screen 210 is not affected by the foaming.

[0058] By replacing the traditional entire frame support structure with a split-type fixing frame structure, when the length of the display screen 210 changes, only the distance between the two fixing frames located at the top and bottom of the display screen 210 needs to be changed, without altering the structure of these two fixing frames, thus reducing manufacturing costs; in one embodiment, such as Figure 1 , Figure 8 As shown, the mounting bracket includes a first mounting bracket 231 and a second mounting bracket 232, which are used to fix the top and bottom of the display screen 210 respectively. When the length of the display screen 210 is changed, only the distance between the first mounting bracket 231 and the second mounting bracket 232 needs to be changed.

[0059] The top and bottom of the display screen 210 are fixed by at least two brackets, thereby restricting the movement of the display screen 210 relative to the two brackets. The two sides of the brackets are then fixed by extrusion strips 233 on both sides, restricting the movement of the brackets relative to the door panel 120, thus enabling the display screen 210 to be installed on the front of the door panel 120. The mounting structure is simple and easy to assemble. Because the door panel 120 separates the display screen 210 from the foam layer, the assembly of the display screen 210 is not affected by the foam. If the display screen 210 malfunctions, the display screen assembly 200 can be removed for timely replacement or repair. Furthermore, when the length of the display screen 210 or the door body changes, only the lengths of the side extrusion strips 233 and the door panel 120 need to be changed to match, while the bracket structure remains unchanged. When the width of the display screen 210 changes, the side extrusion strips 233 do not need to be changed; only the dimensions of the fixing structures securing the top and bottom of the display screen 210 need to be changed. When the width of the door body 101 changes while the size of the display screen 210 remains unchanged, the assembly structure between the side extrusion strips 233 and the door frame 110 can be adjusted. Instead of the traditional one-piece frame fixing solution, when the size of the display screen 210 is changed, there is no need to replace the entire one-piece frame. The display screen 210 is fixed by a split fixing structure at the top, bottom and sides. The structure of each fixing structure is simple and the replacement cost is low.

[0060] In one embodiment, such as Figure 8As shown, the first fixing frame 231 extends towards the display screen 210 on both sides to form two first limiting parts 2311, which are used to abut against the two sides of the top of the display screen 210 to restrict the top of the display screen 210 from moving laterally in the plane.

[0061] And / or, the second fixing bracket 232 extends towards the display screen 210 on both sides to form two second limiting parts 2321, which are used to abut against the two sides of the top of the display screen 210 to restrict the bottom of the display screen 210 from moving laterally in the plane. When the first fixing bracket 231 is provided with two first limiting parts 2311 and the second fixing bracket 232 is provided with two second limiting parts 2321, the first fixing bracket 231 and the second fixing bracket 232 together form an inner frame for fixing the display screen 210. The fixing structure outside the inner frame is formed by the extrusion strips 233 on both sides, so as to install the display screen 210 on the front of the door panel 120.

[0062] In one embodiment, the side extrusion strip 233 is snapped onto the outer side of the door frame 110. Further, since the side extrusion strip 233 is used to fix one side of the mounting bracket, to simplify processing and assembly, the side extrusion strip 233 has a long strip structure that extends along the extension direction of the side trim strip 112 of the door frame 110. For example... Figure 1 , Figure 2 , Figure 3 , Figure 12 As shown, the side extrusion strip 233 has a protrusion 2331 on the side facing the side trim strip 112, and the side trim strip 112 has several second engaging portions 1127. The side extrusion strip 233 and the side trim strip 112 are engaged by the protrusion 2331 engaging with the second engaging portions 1127. Furthermore, the protrusion 2331 is elongated, with a simple structure, making it easy to align with the second engaging portions 1127, thus reducing the precision requirements for its assembly with the second engaging portions 1127.

[0063] Specifically, in one embodiment, such as Figure 11 , Figure 12As shown, the side trim 112 includes a panel 1121; the panel 1121 has a first connecting portion 1122 for mounting the outer surface of the door body 101; wherein, the side of the first connecting portion 1122 facing the fixing frame has a second connecting portion 1123 for detachably mounting two fixing frames. The panel 1121 forms the side wall structure of the door body 101. The first connecting portion 1122 extends along the direction of the outer surface to facilitate the mounting of the outer surface. The door panel 120 is a thin plate structure with relatively weak structural strength. By providing the second connecting portion 1123, it can be detachably assembled with one side of the fixing frame, so that the second connecting portion 1123 fixes one side of the fixing frame. On the one hand, this facilitates the quick installation and removal of the fixing frame; on the other hand, the side trim 112 has a certain structural strength, replacing the solution of opening a fixing structure on one side of the fixing frame in the weaker door panel 120, and can permanently and stably fix one side of the fixing frame.

[0064] Furthermore, such as Figure 3 , Figure 8 As shown, the protrusion 2331 is provided with a second clearance portion 23311 to accommodate the second latching portion 1127, allowing the protrusion 2331 to engage from one end of the second latching portion 1127. Because the protrusion 2331 engages with the inside of the door frame 110, when installing the display screen 210, the protrusion 2331 needs to be inserted from above the corresponding second latching portion 1127. Therefore, the second clearance portion 23311 is required to accommodate the assembly of the second latching portion 1127. The number of second clearance portions 23311 is the same as the number of second latching portions 1127 corresponding to the extrusion strip 233 on that side.

[0065] Specifically, in one embodiment, such as Figure 1 , Figure 2 As shown, the upper cover 113 of the door frame 110 is provided with a first snap-fit ​​portion 11313, and the side trim strip 112 is detachably installed with at least one second snap-fit ​​portion 1127. The support member 111 disposed inside the door frame 110 is provided with two third snap-fit ​​portions 111213 that respectively snap-fit ​​the bottom ends of the protrusions 2331 of the two side extrusion strips 233. The door frame 110 achieves the limitation of one side of the side extrusion strip 233 through the first snap-fit ​​portion 11313, the second snap-fit ​​portion 1127, and the third snap-fit ​​portion 111213, so as to limit the movement of the side extrusion strip 233 relative to the inner wall corresponding to the position of the door frame 110 and limit the movement of the side extrusion strip 233 away from or towards the appliance box 102.

[0066] Furthermore, the second snap-fit ​​portion 1127 is detachably mounted to the second connecting portion 1123 of the side trim strip 112. The detachable connection between the second snap-fit ​​portion 1127 and the second connecting portion 1123 simplifies the structure of the second connecting portion 1123 and reduces its processing mold cost. Only the second snap-fit ​​portion 1127 needs to be additionally processed and prepared. Installing the second snap-fit ​​portion 1127 onto the second connecting portion 1123 achieves the snap-fit ​​connection with the protrusion 2331. Specifically, as... Figure 2 , Figure 11 , Figure 12 As shown, the second connecting part 1123 is provided with a plurality of mounting slots 11231, and the second snap-fit ​​part 1127 extends out of the mounting slots 11231 from the back of the second connecting part 1123. The mounting slots 11231 are simple to open, do not require changes to the processing mold of the side trim strip 112, saving costs, and the second snap-fit ​​part 1127 is easy to install.

[0067] Furthermore, such as Figure 3 , Figure 13 As shown, the second snap-fit ​​portion 1127 includes a fixing base 11271 and a snap-fit ​​base 11272; the snap-fit ​​base 11272 protrudes from the fixing base 11271; the snap-fit ​​base 11272 is used to snap-fit ​​one side of the fixing frame, and the fixing base 11271 is detachably fixed to the second connecting portion 1123. The fixing base 11271 facilitates the installation of the second snap-fit ​​portion 1127 onto the second connecting portion 1123.

[0068] In one embodiment, the second snap-fit ​​part 1127 is a plastic part with a certain degree of elasticity, which facilitates the limiting of the fixing frame and is not easy to damage the fixing frame.

[0069] In one embodiment, the second snap-fit ​​portion 1127 is provided with a fixing structure to be fixed to the door panel 120 by fasteners. Since the second connecting portion 1123 is located close to the door panel 120, in order to simplify the assembly structure of the side trim 112 and the door panel 120, the assembly of the side trim 112 and the door panel 120 is achieved through the connection of the second connecting portion 1123 to the door panel 120. Specifically, in one embodiment, as... Figure 13 As shown, the second snap-fit ​​part 1127 includes a fixing seat 11271 and a snap-fit ​​seat 11272. The fixing seat 11271 is provided with a plurality of first fixing holes 112711 and second fixing holes 112712 for fixing to the door panel 120 and the second connecting part 1123 respectively by fasteners.

[0070] In one embodiment, such as Figure 1 , Figure 9 As shown, the inner side of the side extrusion strip 233 is engaged with one side of the fixing frame. Specifically, the side extrusion strip 233 and the fixing frame are engaged through a slot structure and a engaging protrusion structure. Figure 7As shown, a second slot 2332 is provided on the inner side of the side extrusion strip 233 to engage with the mounting bracket. Since the second slot structure has a certain depth, the side wall of this structure needs to have a certain thickness. The mounting bracket is used to fix the display screen 210, and the display screen 210 is fragile. When installing the display screen 210, it needs to be in contact with the display screen 210 to secure it to the mounting bracket. If a slot is provided on the side wall of the mounting bracket, the side wall of the mounting bracket would be too thick, increasing its weight and hindering the installation of the display screen 210. The second slot 2332 is located on the inner side of the side extrusion strip 233. Because the side extrusion strip 233 has a simple structure, it is easy to create a slot structure. Furthermore, since the side extrusion strip 233 is used to fix the mounting bracket on which the display screen 210 is installed, during assembly, only the side extrusion strip 233 and the mounting bracket need to be in contact; no force needs to be applied to the display screen 210, thus protecting the display screen 210 from damage. At least one snap-fit ​​protrusion is provided on one side of each of the two opposing side extrusion strips 233, and the snap-fit ​​of the side extrusion strip 233 to one side of the frame is secured by limiting the position at two points.

[0071] Furthermore, such as Figure 7 As shown, the second slot 2332 extends along the extension direction of the side extrusion strip 233. Since the side extrusion strip 233 is long, the second slot 2332 is opened along its extension direction to increase the length of the second slot 2332, thereby increasing its engagement force with the engagement protrusions provided on the frame.

[0072] Furthermore, such as Figure 7 As shown, the second slot 2332 gradually narrows in the direction toward the fixing frame. The locking protrusion of the fixing frame is engaged from one end of the second slot 2332. By designing the contour of the second slot 2332, the locking protrusion located in the second slot 2332 will not move away from the side extrusion strip 233, that is, the locking protrusion is prevented from disengaging from the second slot 2332, so as to secure the assembly of the side extrusion strip 233 and the fixing frame.

[0073] In one embodiment, such as Figure 8As shown, a first clearance portion 2333 is provided on the inner side of the side extrusion strip 233. The snap-fit ​​protrusion away from the end of the side extrusion strip 2333 extends into the first clearance portion 2333 and then snaps into the second snap-fit ​​groove 2332. Since the snap-fit ​​protrusion of the fixing frame snaps into the second snap-fit ​​groove 2332 from one end, in order to facilitate the snap-fit ​​between the side extrusion strip and the fixing frame, a first clearance portion 2333 is provided on the inner side of the side extrusion strip 233 to form a snap-fit ​​entrance on the second snap-fit ​​groove 2332. The first clearance portion 2333 is close to the position of the snap-fit ​​protrusion of the fixing frame corresponding to the side extrusion strip 233 when the fixing frame is assembled. During assembly, the snap-fit ​​protrusion of the fixing frame away from the end of the side extrusion strip 233 is aligned with the first clearance portion 2333 and extended in, so that the second snap-fit ​​groove 2332 corresponds to the position of the snap-fit ​​protrusion of the frame, so that the snap-fit ​​protrusion can be snapped into the second snap-fit ​​groove 2332. It is not necessary to move all the snap-fit ​​protrusions of the frame to one side of the second slot 2332 before snapping them in, thus reducing the space occupied during assembly.

[0074] Specifically, in one embodiment, such as Figure 1 , Figure 8 , Figure 9 , Figure 16 As shown, the fixing frame includes a first fixing frame 231 and a second fixing frame 232; the first fixing frame 231 and the second fixing frame 232 are respectively provided with a first locking protrusion 2312 and a second locking protrusion 2322 on one side opposite to the extrusion strip 233. The first fixing frame 231 is located at the top of the display screen 210, and the second fixing frame 232 is located at the bottom of the display screen 210; and the display screen 210 is located near the top of the door frame 110. Since the door body 101 is relatively long, the second fixing frame 232 is located near the middle position inside the door frame 110. Therefore, the position of the first locking protrusion 2312 is close to the top of the second locking groove 2332, and the position of the second locking protrusion 2322 is far away from both ends of the second locking groove 2332. The side extrusion strip 233 has a first clearance portion 2333 near the second snap-fit ​​protrusion 2322. When assembling the side extrusion strip 233 with the frame, the first snap-fit ​​protrusion 2312 is located at the top of the second slot 2332, and the second snap-fit ​​protrusion 2322 extends into the first clearance portion 2333. The side extrusion strip 233 is then pushed upward so that the first snap-fit ​​protrusion 2312 and the second snap-fit ​​protrusion 2322 are snapped into the second slot 2332.

[0075] In one embodiment, such as Figure 1 As shown, it also includes a support member 111, which supports the bottom of the display screen 210 and serves to bear the weight.

[0076] Furthermore, such as Figure 4As shown, the support member 111 is provided with a second support portion 111214 for supporting the side extrusion strip 233. The support member 111 supports the bottom of the side extrusion strip 233, and the side extrusion strip 233 fixes the two fixing frames, thereby supporting the display screen 210. In one embodiment, the support member 111 is also provided with a third locking portion 111213; the support member 111 supports the bottom of the side extrusion strip 233 through the second support portion 111214, and the third locking portion 111213 locks the protrusion 2331 of the side extrusion strip 233, thereby restricting the movement of the bottom of the side extrusion strip 233 away from or near the door panel 120.

[0077] Furthermore, to facilitate the design of the thickness relationship between the side extrusion strip 233 and the fixing frame, the side extrusion strip 233 and the fixing frame are limited to have the same thickness, and the back of the side extrusion strip 233 is flush with the back of the fixing frame. To dissipate the heat generated by the display screen 210 during operation, gaps are left between the display screen 210, the fixing frame, and the door panel 120 to form ventilation channels. Therefore, a gap is also left between the back of the side extrusion strip 233 and the door panel 120, meaning the back of the protrusion 2331 of the side extrusion strip 233 does not contact the door panel 120. When assembling the display screen 210, if... Figure 8 , Figure 9 As shown, the top and bottom of the display screen 210 are fixed by the first fixing bracket 231 and the second fixing bracket 232, respectively; the two sides of the two fixing brackets are fixed by the extrusion strips 233 on both sides. The first fixing bracket 231, the second fixing bracket 232, and the extrusion strips 233 on both sides together form a bracket 230 for fixing the display screen 210. A first panel 220, which is a glass panel, is glued to the front of the bracket 230 on which the display screen 210 is fixed, thus obtaining the display screen assembly 200. The first panel 220 is glued to the door frame 110, thus completing the assembly of the display screen assembly 200 and the foamed door assembly 100. Due to the bonding of the first panel 220 to the door frame 110, the movement of the side extrusion strips 233 towards the door panel 120 and the upward movement of the side extrusion strips 233 are restricted; as Figure 1As shown, the front of the protrusion 2331 of the side extrusion strip 233 abuts against the first latching part 11313, the second latching part 1127, and the third latching part 111213, thereby restricting the movement of the side extrusion strip 233 away from the door panel 120 by the first latching part 11313, the second latching part 1127, and the third latching part 111213; and the support member 111 supports the bottom of the side extrusion strip 233, thereby restricting the downward movement of the side extrusion strip 233. By limiting the side extrusion strip 233, the display screen 210 is fixed. Furthermore, since the back of the protrusion 2331 does not contact the door panel 120, the distance between the first latching part 11313, the second latching part 1127, and the third latching part 111213 and the door panel 120 is greater than the thickness of the protrusion 2331. The first latching part 11313, the second latching part 1127, and the third latching part 111213 have a larger accommodating space, which facilitates the insertion of the protrusion 2331.

[0078] In one embodiment, such as Figure 4 As shown, the inner side of the side extrusion strip 233 is provided with a first support part 2334 to support one side of the back of the display screen 210, so that a channel is formed between the display screen 210 and the door panel 120 on its back which is used to separate the foam layer, for ventilation and heat dissipation, so that the display screen 210 can dissipate heat.

[0079] Furthermore, the first support portion 2334 is relatively close to the door panel 120, and its back side abuts against the front side of the support member 111. The first snap-fit ​​portion 11313, the second snap-fit ​​portion 1127, and the third snap-fit ​​portion 111213 press the front side of the protrusion 2331 of the side extrusion strip 233, and the support member 111 presses the back side of the first support portion 2334 of the side extrusion strip 233, thereby restricting the movement of the side extrusion strip 233 toward or away from the door panel 120.

[0080] Furthermore, in order to better fix the side extrusion strip 233, such as Figure 4 , Figure 5 As shown, the support member 111 is provided with a second abutment 1117, which abuts against the side of the first support member 2334 facing the display screen 210, so as to restrict the movement of the side extrusion strip 233 toward the display screen 210.

[0081] Specifically, in one embodiment, the door body 101 is relatively long, covering the storage compartment and / or freezer compartment in the same longitudinal direction of the appliance cabinet 102, providing users with a smart experience while reducing the number of doors and simplifying the front structure of the appliance. For longer appliance door structures, if a single panel is used as the outer surface, the panel must match the size of the appliance door, resulting in a long panel, inconvenient installation, and strict requirements for the assembly precision between the panel and the appliance door frame. Therefore, replacing a single panel with at least two sequentially arranged panels as the outer surface of the door reduces the difficulty of assembling the outer surface with the door frame and lowers the assembly precision requirements. Furthermore, the number of panels can be increased or decreased to match user needs and assembly precision requirements. To simplify the processing steps, such as... Figure 1 , Figure 2 , Figure 17 As shown, the door body 101 has two panels, namely, the first panel 220 and the second panel 130, which together form the outer surface of the door body 101; the first panel 220 is a glass panel and a display screen 210 is disposed on its back. A detailed explanation will be given using the door body 101 having the first panel 220 and the second panel 130 as an example. Figure 8 , Figure 9 As shown, after the first fixing bracket 231 and the second fixing bracket 232 are respectively abutted against the top and bottom of the display screen 210, the extrusion strips 233 on both sides are slid down to respectively lock the first fixing bracket 231 and the second fixing bracket 232 on both sides, as shown. Figure 1 As shown, the third limiting portions 2313 provided on both sides of the first fixing frame 231 abut against the tops of the extrusion strips 233 on both sides; as Figure 9 As shown, after the control board 240 is installed on the first mounting bracket 231 or the second mounting bracket 232, the first panel 220 is bonded to the front of the first mounting bracket 231, the second mounting bracket 232, and the extruded strips 233 on both sides forming the frame, thus obtaining the display screen assembly 200. Figure 2 As shown, the side trim strips 112, upper cover 113, support member 111, door panel 120, partition (not shown in the figure), lower cover 114, and door core are assembled, and foaming material is injected to form a foam layer, thus assembling a foamed door assembly 100; the second panel 130 is installed at the corresponding position on the door frame 110, and the partition is used to separate the foam layer from the second panel 130; the door frame includes an upper cover 113, side trim strips 112, and support member 111; as shown Figure 1 , Figure 4As shown, the protrusions 2331 of the two extrusion strips 233 respectively fit into the snap-fit ​​portions provided inside the door frame 110, and the bottom ends of the two extrusion strips 233 abut against the second support portion 111214 of the support member 111, thereby installing the display screen assembly 200 on the front of the foam door assembly 100. Through the adhesive force between the first panel 220 and the front of the door frame 110, the display screen assembly 200 is stably and fixedly installed on the front of the foam door assembly 100. Due to the adhesive force between the first panel 220 and the door frame 110, the first panel 220 is not easy to move relative to the door frame 110, so the first fixing bracket 231, the second fixing bracket 232, and the two extrusion strips 233 on the back of the first panel 220 will not move within the door frame 110.

[0082] In one embodiment, such as Figure 5 , Figure 6 As shown, the support member 111 is provided with a plurality of fourth snap-fit ​​portions 111211 for snapping onto the bottom of the door panel 120. The door panel 120 has a thin plate structure, and the fourth snap-fit ​​portions 111211 have a slot structure. One end of the door panel 120 is snapped into the fourth snap-fit ​​portion 111211, thereby restricting the movement of the door panel 120 toward the support member 111. The number of fourth snap-fit ​​portions 111211 can be two or more. To save costs, the number of fourth snap-fit ​​portions 111211 is two to securely snap onto the door panel 120. Furthermore, the back of the support member 111 abuts against the door panel 120 to seal the assembly point of the support member 111 and the door panel 120 and prevent foam overflow.

[0083] In one embodiment, such as Figure 5 As shown, the support member 111 has a second mounting portion 111212 for fixing the door panel 120. The support member 111 is used to fix one end of the door panel 120. The second mounting portion 111212 is a mounting hole, and fasteners are used for fixing. Specifically, when installing the door panel 120, one end of the door panel 120 is inserted into the fourth snap-fit ​​portion 111211, and fasteners are used to pass through the second mounting portion 111212 in sequence to fix it to the door panel 120.

[0084] In one embodiment, such as Figure 5 , Figure 6As shown, the support member 111 is provided with a first fixing part 1114 for fixing the lamp panel 411, so that the light emitted by the lamp panel 411 shines downward from the side of the glass panel to form ambient light around the glass panel. Specifically, the outer surface is the decorative surface structure on the front of the door body 101. To avoid the foam layer affecting the illumination of the lamp panel 411, the support member 111 is provided with a vertical plate 1112 to separate the lamp panel 411 and the foam layer. In one embodiment, the vertical plate 1112 is provided with a cavity, and the outer contour of the front of the vertical plate 1112 abuts against the back of the outer surface. The vertical plate 1112 and the outer surface together form a sealed space to accommodate the lamp panel, thereby separating the lamp panel from the foam layer. In another embodiment, the vertical plate 1112 of the support member 111, together with the door panel 120, the side trim strips 112, and the upper cover 113, forms a space for configuring the display screen 210, thereby separating the display screen 210 and the lamp panel mounted on the support member 111 from the foam layer. The support member 111 is provided for mounting the lamp panel, making lamp panel installation convenient.

[0085] In one embodiment, the first fixing part 1114 protrudes from the front of the vertical plate 1112. Specifically, the first fixing part 1114 protrudes from the vertical plate 1112, leaving a space between the lamp plate 411 and the vertical plate 1112 after the lamp plate 411 is installed, facilitating heat dissipation during the illumination process. The first fixing part 1114 is provided with mounting holes for quick installation of the lamp plate 411. The lamp plate 411 includes a fixing plate 4111 and a plurality of LED lights 4112; the plurality of LED lights 4112 are fixed on the fixing plate 4111; the fixing plate 4111 is fixed to the first fixing part 1114, thus realizing the assembly of the LED lights. Furthermore, the plurality of LED lights 4112 are evenly distributed to improve the uniformity of light emission from the light-emitting part.

[0086] In one embodiment, the support member 111 is provided with a second fixing part for fixing the lampshade 412 of the lamp panel. Specifically, the lamp panel is provided with a lampshade 412, which is located between the lamp panel 411 and the glass panel below the lamp panel 411 for emitting light. By designing the light emission effect of the lampshade 412, such as the light refractive index design, the light emitted from the lamp panel 411 is diffused, making the light emission from the outer surface of the door body 101 soft. In addition, when the outer surface has an opening, the lampshade 412 is used to prevent external dust or flying pollutants from entering through the opening and depositing on the surface of the lamp panel 411, thus hindering its light emission effect. Furthermore, the support member 111 is provided to fix the lampshade 412 and the vertical plate separates the lampshade 412 from the foam layer, making the installation of the lampshade 412 convenient.

[0087] Furthermore, the second fixing part is installed with the lampshade 412 by means of snap-fit, snap-fit, or fastener connection, so as to realize the quick installation and removal of the lampshade 412.

[0088] In one embodiment, the second fixing part includes at least two snap-fit ​​structures that form opposing snap-fit ​​forces to press the lampshade 412 onto the vertical plate. The lampshade 412 is secured by at least two snap-fit ​​structures, making it easy to install or remove.

[0089] In one embodiment, the second fixing part includes a third buckle 111215 and abutment plate 111216. The third buckle 111215 fastens the outer end of the lampshade 412 and, together with the abutment plate 111216, forms a pressure against the two sides of the lampshade 412. Through the cooperation of the third buckle 111215 and the abutment plate 111216, the corresponding parts of the lampshade 412 are fixed, enabling quick installation and removal. Furthermore, reducing the number of third buckles 111215 lowers the difficulty of fastening, facilitating the installation of the lampshade 412. Further, the lampshade 412 narrows at both ends to form a third mounting part 4121, which matches the second fixing part for assembly. The narrowing of the lampshade 412 and the smaller size of the matching third buckle 111215 facilitate the miniaturization design of the support member 111.

[0090] Furthermore, such as Figure 5 As shown, the support member 111 is provided with a plurality of support ribs 111217 for supporting the bottom surface of the lampshade 412 on the lamp panel. The two ends of the lampshade 412 are fixed by two second fixing parts respectively, and the bottom surface of the lampshade 412 is supported by a plurality of support ribs 111217, thereby reducing the number of second fixing parts while firmly fixing the lampshade 412.

[0091] In one embodiment, such as Figure 6 As shown, the support member 111 has at least two mounting surfaces for attaching the exterior finish of the door body 101; the two mounting surfaces are staggered in height to support the two panels and form openings 500 at the ends of the two panels. The support member 111 supports the back sides of the ends of two adjacent panels to secure the installation of the two panels. The openings 500 can be used for air intake to dissipate heat from the display screen 210; they can also be used for light emission, allowing the light emitted from the light panel 411 to illuminate the exterior finish, serving as an illumination indicator. Specifically, as... Figure 4 , Figure 5 , Figure 6As shown, the support member 111 has a first mounting surface 1113 and a second mounting surface 11122, which are used to attach the back sides of the first panel 220 and the second panel 130 of the door body 101 to form the door decorative surface, respectively. Since the back side of the panel is flat, if the front surface of the support member 111 is used to abut against the back side of the two panels, the matching degree between the front surface of the support member 111 and the back side of the panel is required to be high, and the assembly precision of the support member 111 and the panel is difficult to control. By setting the first mounting surface 1113 and the second mounting surface 11122, a supporting effect is formed on the back side of one end of the two corresponding panels. At the same time, by reducing the contact surface area between the support member 111 and the two corresponding panels, the assembly difficulty of the support member 111 and the two corresponding panels is reduced. By designing the distance between the first mounting surface 1113, the second mounting surface 11122 and the appliance box 102, the two panels are attached in a staggered manner.

[0092] In one embodiment, such as Figure 4 As shown, a pad 115 is provided on the front of the first connecting part 1122 corresponding to the position of the first panel 220. The pad 115 is used to adhere to the first panel 220 on which the display screen 210 is located. The back of the two side ends of the two panels are attached by the side trim strips 112. The bottom end of the first panel 220 and the top end of the second panel 130 are respectively attached to the first mounting surface 1113 and the second mounting surface 11122 through the support member 111. By designing the distance between the first mounting surface 1113, the second mounting surface 11122 and the appliance box 102, the first panel 220 and the adjacent second panel 130 are staggered to form an opening 500 on the outer surface.

[0093] Furthermore, the first mounting surface 1113 and / or the second mounting surface 11122 are plate-like structures, which are simple in structure, easy to process, have high structural strength, and provide stable support.

[0094] Furthermore, the first mounting surface 1113 and / or the second mounting surface 11122, which are plate-shaped, are arranged laterally to reduce the contact surface area between the first mounting surface 1113 and / or the second mounting surface 11122 and the corresponding panel, thereby reducing assembly difficulty. In one embodiment, the support member 111 includes a first vertical plate 11121 and a second vertical plate. The first vertical plate 11121 is provided with a first mounting surface 1113, which is arranged laterally, and one side surface of which is used to abut against the first panel 220. The second vertical plate forms a second mounting surface 11122 on its front side, which is used to abut against the second panel 130.

[0095] To facilitate the arrangement of the wiring harness for electrical connection of the lamp board 411, the lamp board 411 is positioned behind the first panel 220 on the back where the display screen 210 is located, that is, the lamp board 411 is positioned close to the display screen 210, so as to facilitate electrical connection between the lamp board 411, the display screen 210 and the control board 240.

[0096] Specifically, in one embodiment, the two panels of the door body 101 are staggered to form an opening 500. The light panel 411 includes a fixing plate 4111 and a plurality of LED lights 4112 disposed on the fixing plate 4111. The fixing plate 4111 is rectangular, and the lampshade 412 is rectangular. The fixing plate 4111 is vertically arranged, and the lampshade 412 is horizontally arranged. The portion of the outer surface corresponding to the position of the light panel 411 is opaque, with some light emanating from the opening 500; some light enters from the top of the second panel 130 and forms a halo around the periphery of the second panel 130.

[0097] In one embodiment, the support member 111 is provided with a ventilation structure, which, together with the opening 500, forms an air intake passage for heat dissipation of the display screen. The ventilation structure in the support member 111 facilitates the flow of heat-dissipating air entering from the opening towards the display screen 210, thereby achieving heat dissipation. The air intake passage structure is simple and has good ventilation performance, replacing the solution of opening an air intake channel on the door frame of the appliance door, thus simplifying the door frame processing mold.

[0098] Furthermore, the ventilation structure includes ventilation holes 1111 and / or ventilation gaps 1116 to ensure the ventilation of the support member 111.

[0099] Furthermore, a ventilation structure is provided on the first mounting surface 1113. Specifically, the first mounting surface 1113 is a plate-like structure arranged horizontally, and one side of the first mounting surface 1113 is used to attach the first panel 220. The ventilation structure is directly provided on the first mounting surface 1113 to control the ventilation volume of the air intake channel. The ventilation structure is simple to provide, reducing the space occupied by the ventilation structure within the appliance door body 101. Figure 4 , Figure 5 As shown, ventilation holes 1111 are opened on the first mounting surface 1113. By controlling the aperture of the ventilation holes 1111, air is introduced while the first mounting surface 1113 forms an air filter structure for filtration. The airflow entering through the opening of the door body 101 is filtered to remove dust, paper scraps, wire ends, or other contaminants from the airflow entering the door body 101, so as not to affect the normal use of the display screen 210.

[0100] In one embodiment, the upper cover 113 is provided with a fan 330 so that airflow enters the ventilation duct from the opening 500.

[0101] Furthermore, such as Figure 5As shown, the side of the first mounting surface 1113 facing the opening 500 is recessed to form several recesses 11131; each recess 11131 is provided with a ventilation structure. The recesses 11131 form an airflow buffer zone, reducing the airflow velocity through the ventilation structure and thus reducing airflow noise. Furthermore, the ventilation structure in the recesses 11131 is a ventilation hole 1111. Since the ventilation hole 1111 has a small diameter and low ventilation volume, the recesses 11131 are used to reduce the airflow velocity entering the ventilation hole 1111. Furthermore, the first mounting surface 1113 is provided with a notch 1116 to increase the ventilation velocity.

[0102] In one embodiment, such as Figure 4 , Figure 5 As shown, the support member 111 has a first mounting portion 1115 at each end for fixing to the side trim strips 112 of the door frame 110. To ensure the structural strength of the door frame 110, the side trim strips 112 are made of aluminum alloy. Since the support member 111 is used to support the back ends of adjacent panels, it is made of plastic to reduce processing costs, making it difficult to integrally mold the support member 111 and the side trim strips 112. By providing the first mounting portions 1115 at both ends of the support member 111, the assembly of the support member 111 and the side trim strips 112 is facilitated, and the overall processing cost of the door body 101's mounting frame is reduced. Specifically, the first mounting portion 1115 has mounting holes to allow for the installation of the first mounting portion 1115 and the side trim strips 112 using fasteners.

[0103] Furthermore, the first mounting part 1115 has a plate-like structure, with its back side abutting against the front side of the side trim 112. The support member 111 is mounted from the front side of the side trim 112, making assembly easy. In addition, the back side of the first mounting part 1115 abuts against the side trim 112 to increase the assembly firmness between the first mounting part 1115 and the side trim 112.

[0104] Furthermore, the first mounting portion 1115 abuts against at least one panel to increase the assembly firmness between the support member 111 and the at least one panel. In one embodiment, the first mounting portion 1115 abuts against the back sides of two panels to increase the support force of the support member on the two panels. In yet another embodiment, the first mounting portion 1115 has a smaller longitudinal length and is used to support the back side of a panel.

[0105] In one embodiment, such as Figure 10 As shown, the side trim 112's plate 1121 partially extends to form a mounting platform 1124 on the side corresponding to the position of the first panel 220, for bonding to the back of the first panel 220. The plane of the mounting platform 1124 and the front of the first connecting portion 1122 form a space to accommodate the pad strip 115. Specifically, as... Figure 4As shown, a pad strip 115 is provided on the front of the first connecting part 1122, and the back of the first panel 220 is adhered to the pad strip 115. The pad strip 115 is used to increase the distance between the first panel 220 and the surface of the first connecting part 1122, thereby making the distance between the first panel 220 and the appliance box 102 greater than the distance between the second panel 130 and the appliance box 102. Furthermore, in order to stabilize the support of the back edge of the first panel 220, a mounting platform 1124 is provided on the plate 1121 to support the back edge of the first panel 220.

[0106] Furthermore, such as Figure 10 As shown, the mounting platform 1124 is provided with a first edge band 11241 to cover a portion of the side wall of the first panel 220, so as to cover the assembly gap between the first panel 220 and the mounting platform 1124 and improve the aesthetics of the side wall of the door body 101.

[0107] Furthermore, the first edge band 11241 protrudes from the mounting platform 1124 by a distance of 1-2mm, which serves to cover the assembly gap between the first panel 220 and the mounting platform 1124, exposing a larger surface area of ​​the side wall of the first panel 220 and showcasing the texture of the glass panel to a greater extent.

[0108] In one embodiment, such as Figure 10 , Figure 11 As shown, the plate 1121 extends partially on one side corresponding to the position of the second panel 130 to form a second edging 1125, which is used to cover a partial sidewall of the second panel 130 to cover the assembly gap between the second panel 130 and the first connecting part 1122.

[0109] In one embodiment, such as Figure 10As shown, the outer end of the first connecting part 1122 is bent towards the appliance box 102 to form a connecting part 1126; the connecting part 1126 connects to the second connecting part 1123, so that the outer wall of the connecting part 1126 and the front surface of the second connecting part 1123 form a cavity to accommodate part or all of the bracket 230. Specifically, the display screen 210 is fixed by the bracket 230. In order to securely fix the display screen 210, the bracket 230 has a certain structural strength and a certain thickness. After the first panel 220 is bonded to the pad strip 115 and the mounting platform 1124, there must be a space of sufficient thickness between the first panel 220 and the door panel 120 of the door body 101 to accommodate the bracket 230 on which the display screen 210 is fixed. By providing the connecting portion 1126, the distance between the second connecting portion 1123 and the first panel 220 is increased, so that the plane where the second connecting portion 1123 is located and the plane where the first connecting portion 1122 is located form a receiving space to accommodate the partial bracket 230. Due to the provision of the spacer strip 115, after the bracket 230 is installed, the front of the bracket 230 is flush with the front of the spacer strip 115, so that the first panel 220 can be simultaneously bonded to the front of both the spacer strip 115 and the bracket 230.

[0110] In one embodiment, such as Figure 10 , Figure 13 As shown, the second connecting part 1123 is recessed towards the appliance box 102 away from the plate 1121, forming the first abutting part 1128; the front of the first abutting part 1128 abuts against the back side of the door panel 120 of the door body 101 to secure the assembly of the second connecting part 1123 and the door panel 120.

[0111] Furthermore, the front of the door panel 120 is flush with the front of the second connecting part 1123, and the door panel 120 and the second connecting part 1123 together form the front structure of the cavity for foaming.

[0112] In one embodiment, such as Figure 10 , Figure 14 As shown, the inner surface of the plate 1121 is provided with at least two bent portions 11211, which form a slot structure with opposite opening directions to respectively engage the third engaging protrusion 1134 of the upper end cover 113 and the fourth engaging protrusion of the lower end cover 114. Specifically, there are two bent portions 11211, and the two slot structures formed have opposite opening directions. The engaging relationship between the upper end cover 113 and the plate 1121 is used as an example for further explanation. Figure 15As shown, the upper cover 113 is provided with two third snap-fit ​​protrusions 1134 and two through grooves 1135. One side wall of the bent portion 11211 is inserted into the through groove 1135 and then snaps into the corresponding third snap-fit ​​protrusion 1134; that is, the movement of the upper cover 113 in the direction away from or towards the appliance box 102 is restricted by the two bent portions 11211 with opposite opening directions, which plays a role in positioning and pre-installation. Furthermore, the first connecting portion 1122 and the upper cover 113 are respectively provided with corresponding mounting holes so as to fix the first connecting portion 1122 and the upper cover 113 by fasteners. Furthermore, due to the limiting effect of the through groove 1135 on one side wall of the bent portion 11211 provided in the upper end cover 113, the number of the third snap-fit ​​protrusion 1134 provided in the upper end cover 113 can also be one. The bent portion 11211 cooperates with the through groove 1135 and the third snap-fit ​​protrusion 1134 respectively to achieve the positioning and pre-assembly of the plate body 1121 and the upper end cover 113. The positioning and pre-assembly of the lower end cover 114 and the plate body 1121 is similar to that of the upper end cover 113, and will not be described in detail here.

[0113] In one embodiment, the plate 1121 is provided with a third connecting part 1129 for installing the door shell (not shown in the figure) of the door body 101.

[0114] Furthermore, such as Figure 11 As shown, Figure 14 , Figure 15 As shown, the third connecting part 1129 is provided with at least two first slots 11291, which are respectively engaged with the first buckle 1136 provided on the upper end cover 113 and the second buckle (not shown in the figure) provided on the lower end cover 114, so as to strengthen the assembly firmness of the side trim strip 112 with the upper end cover 113 and the lower end cover 114 respectively.

[0115] In one embodiment, the plate 1121 is provided with a fixing groove for installing a door handle so that the user can open the door body 101.

[0116] Example 2

[0117] This invention provides a door for home appliances, including a door body 101, such as... Figures 1 to 17 As shown, the door body 101 includes:

[0118] Display screen 210;

[0119] The mounting structure of the door display screen described above is used to mount the display screen 210.

[0120] In one embodiment, the door body 101 includes at least two panels to jointly form the exterior surface of the door body 101. By using at least two sequentially arranged panels instead of a single panel as the exterior surface of the door, the difficulty of assembling the exterior surface with the door frame is reduced, and the assembly accuracy requirements are lowered. In addition, the number of panels can be increased or decreased to match user needs and assembly accuracy requirements.

[0121] In one embodiment, there are two panels. Two panels can reduce the difficulty of panel assembly due to the long longitudinal dimension of the door body 101, and at the same time simplify the number of panels, so as to simplify the assembly process of the outer surface of the door body 101.

[0122] The following is a detailed explanation using the example of a door body 101 having a first panel 220 and a second panel 130 on its outer surface. The door body 101 is provided with a door panel 120, which separates the display screen and the foam layer of the door body 101. The door frame 110 includes side trim strips 112, an upper cover 113, and a lower cover 114, which respectively form the side frame structures. The support member 111, the first panel 220, the side trim strips 112, the upper cover 113, and the door panel 120 together form a space for accommodating the display screen 210; the partition, support member 111, door panel 120, side trim strips 112, upper cover 113, lower cover 114, and door liner together form a space for accommodating the foam layer, wherein the partition, support member 111, and door panel 120 form a surface structure of this space that faces away from the appliance box 102. The bracket 230 includes a first fixing frame 231, a second fixing frame 232, and two side extrusion strips 233. The side extrusion strips 233 are fixed to the corresponding side trim strips 112. The first fixing frame 231 and the second fixing frame 232 are respectively fixed to one side extrusion strip 233. The first fixing frame 231 and the second fixing frame 232 are used to fix the top and bottom of the display screen 210, respectively, and the two side extrusion strips 233 are used to fix the first fixing frame 231 and the second fixing frame 232 on both sides. The control board 240 provided on the door body 101 for electrical connection with the display screen 210 is set on the second fixing frame 232. A gap is left between the first fixing frame 231, the second fixing frame 232 and the door panel 120 to form a corresponding ventilation channel. Specifically, the ventilation ducts, from bottom to top, include a first ventilation duct, a second ventilation duct, a third ventilation duct, and a fourth ventilation duct. The first ventilation duct is formed between the lower back of the first panel 220 and the door panel 120; the second ventilation duct is formed between the second fixing bracket 232 and the door panel 120; the third ventilation duct is formed between the back of the display screen 210 and the door panel 120; and the fourth ventilation duct is formed between the first fixing bracket 231 and the door panel 120. The fourth ventilation duct is connected to the air outlet. The air outlet (not shown in the figure) is located on the upper cover 113. Outside air enters through the opening 500, is filtered by the first mounting surface 1113 of the support member 111 which has a ventilation structure, and then enters the ventilation duct, successively contacting the control board 240 and the display screen 210 to dissipate heat from the control board 240 and the display screen 210.

[0123] The support member 111 is equipped with a light panel 411; the door body 101 is equipped with a human body sensing module (not shown in the figure); the control board 240 is electrically connected to the light panel 411 and the human body sensing module respectively; the light panel 411 lights up or turns off according to the instructions issued by the control board 240 based on the sensing information received from the human body sensing module. Further, the human body sensing module includes an infrared sensing module or a microwave sensing module; the infrared sensing module senses changes in the infrared spectrum of the human body to send different signals to the control board 240, or the microwave sensing module senses changes in microwaves caused by the human body to send different signals to the control board 240. When a user approaches a home appliance, the human body sensor module detects that the distance between the user and the appliance reaches a threshold for turning on the light. It then sends a light-on instruction to the control board 240, which in turn sends a light-on command to the lamp panel 411, causing the lamp panel 411 to illuminate. Conversely, when the user moves away from the appliance, the human body sensor module detects that the distance between the user and the appliance exceeds the threshold for turning on the light. It then sends a light-off instruction to the control board 240, which in turn sends a light-off command to the lamp panel 411, causing the lamp panel 411 to turn off the light. The human body sensor module can be located on the top or bottom end cover of the door body 101, but for more accurate sensing of the distance between the user and the appliance, it is located inside the panel of the door body 101. This design is intelligent and energy-saving, preventing the lamp panel 411 from remaining constantly lit and generating heat, which would hinder heat dissipation and reduce the lifespan of the lamp panel 411. Furthermore, the door body 101 is also equipped with a photosensitive sensor to sense the light intensity of the surrounding environment of the appliance. The photosensitive sensor is electrically connected to the control board 240. When the photosensitive sensor detects that the light intensity of the surrounding environment of the appliance is lower than the light threshold required to turn on the light, and the human body sensing module detects that the distance between the human body and the appliance reaches the threshold for turning on the light, the light panel 411 lights up. When the photosensitive sensor detects that the light intensity of the surrounding environment of the appliance is higher than the light threshold required to turn on the light, the light panel 411 does not light up.
