[0033] Compared with the prior art, the present invention has the following beneficial effects:

[0034] The present invention provides a home appliance display screen door body, which is provided with a foaming layer, has an interactive function and provides good thermal insulation performance.

[0035] In a preferred embodiment, the door panel body can be quickly pre-installed with the bracket body through the fixing seat, so that the display screen assembly is installed on one side of the door panel body, and the foam door body assembly is connected with the display screen assembly to assemble into the home appliance door body. The door panel body plays the role of receiving the display screen assembly and the foam door body assembly. The bracket body is detachable, which is convenient for disassembly and maintenance of the display screen. In one embodiment, the door panel body includes a thin plate structure, and the fixing seat is arranged on one side of the thin plate structure. The thin plate structure is thin, so that the foam door body assembly is thinner as a whole, and ultimately the refrigerator door body is thinner and small in size, which is conducive to market competition. The fixing seat has a simple structure and is easy to install. It limits the movement of the bracket body in at least one direction, is easy to install, is suitable for bracket bodies of different sizes, and is convenient for disassembly of the bracket body, and is not affected by the foaming process. In a preferred embodiment, the door panel body is a sheet metal part, which is easy to process and does not require re-molding. After the bracket body for fixing the display screen is installed on the door panel body, on the one hand, the foam door body provides thermal insulation performance for the home appliance door body. On the other hand, the heat generated during the use of the display screen can be promptly transferred to the outside through the thermal conductivity of the sheet metal part to dissipate heat, protect the display screen, and avoid overheating of the display screen.

[0036] In a preferred embodiment, the upper end cover body includes a first cover body and a second cover body. The first cover body is provided with a drainage groove, and the second cover body is used to conceal the drainage groove. When water accumulates on the upper surface of the upper end cover body, the water will flow into the drainage groove along the connection between the first and second cover bodies, or first enter the area around the drainage groove before flowing into the drainage groove, ultimately achieving drainage. This simple structure can not only drain the accumulated water on the upper end cover body, but also does not affect the overall appearance of the upper end cover body and prevent dust accumulation. Furthermore, the first cover body is provided with a diversion cavity, and the second cover body is provided with a diversion protrusion and a diversion groove, which guide the water entering the first groove, draining it in an orderly and smooth manner without affecting the terminal and / or knocking module in the second groove. This diversifies the functions of the end cover and avoids potential circuit safety hazards caused by water. Furthermore, the first cover body is provided with a second recess for accommodating the wiring terminals and the knocking module. The through-slot guides the wiring harness from inside the upper cover body to the wiring terminals. The first through-hole and the through-slot cooperate to guide the wiring harness outside the appliance door to the wiring terminals. The second cover body conceals the wiring terminals and the knocking module, protecting the second recess from dust and moisture and providing a sleek and aesthetically pleasing appearance. The placement of the wiring terminals simplifies wiring, resulting in a simple and compact structure that facilitates wiring. When the wiring terminals or the knocking module require repair or replacement, the second cover body can be opened for easy access. In a preferred embodiment, the second cover body is provided with a first abutment portion to compress the top of the bracket body.

[0037] In a preferred embodiment, the lower end cover body is provided with a second abutting portion to press the bottom end of the bracket body, stabilize the installation of the bracket body, and improve the installation speed and accuracy. In a preferred embodiment of the present invention, the lower end cover body includes a bottom plate, and a fixing plate is also provided on the bottom plate. The fixing plate separates the lower end cover body into a foaming area and a pressing area. The pressing area is provided with a second abutting portion. The foaming area constitutes an end sealing structure at one end of the door body to be connected with other structures of the door body to form a sealed space for foaming; further, the fixing plate is provided with a second clamping notch for clamping the door panel body of the refrigerator door body and a second mounting portion for achieving a fixed connection with the door panel body, which also reduces the requirements for installation accuracy between the lower end cover body and the door panel body, and improves the installation speed and accuracy. The structure is simple, has a positioning pre-installation function, and is easy to assemble.

[0038] In a preferred embodiment, the appliance door also includes a logo display assembly, enhancing the door's aesthetics while also serving as a warning. Furthermore, without the need for a light-emitting component mounting bracket, the light-emitting component is directly mounted on the light-emitting component port on the main control board, simplifying the bracket's main structure and conserving space between the transparent panel and the bracket. Furthermore, a transparent adhesive layer is provided to prevent bubbles from forming on the contact side of the one-way film and the transparent panel, which could cause light beam refraction. Furthermore, by placing the microphone adjacent to the logo, the user's immersive experience is enhanced.

DETAILED DESCRIPTION

[0080] In order that the invention described herein may be more fully understood, the following examples are set forth. It should be understood that these examples are for illustrative purposes only and should not be construed as limiting the present invention in any manner.

[0081] Example 1

[0082] like Figure 1 As shown, the present invention provides a home appliance display screen door, including a home appliance door 10 for forming a closed cavity of the home appliance, the home appliance door 10 includes a foam door assembly 100 and a display screen assembly 200; the foam door assembly 100 is provided with a foam layer; the display screen assembly 200 includes a bracket body 210, a display screen 220, a transparent panel 230, and a main control board 240; the display screen 220 is fixed on the bracket body 210 and electrically connected to the main control board 240; the transparent panel 230 is attached to one side of the bracket body 210; wherein,

[0083] The bracket body 210 matches the size of the foam door assembly 100 , and the side of the bracket body 210 on which the display screen 220 is installed, away from the transparent panel 230 , is detachably connected to one side of the door panel body 120 of the foam door assembly 100 .

[0084] In one embodiment, the home appliance door 10 serves as a refrigerator door and is pivotally connected to one side of the home appliance housing.

[0085] like Figure 2 As shown, the foam door assembly 100 includes a door panel body 120, a door liner 140, and a door body door frame; the door panel body 120 and the door liner 140 are arranged opposite to each other, and the door liner 140 is fixed on the side close to the home appliance box, and together with the door body door frame, forms a sealed space, and the sealed space is provided with a foam layer to provide thermal insulation performance.

[0086] like Figures 2 to 4 As shown, the door panel body 120 is provided with a plurality of fixing seats 122, at least two of which are respectively located outside the two opposite outer walls of the bracket body 210, and abut against the two opposite outer walls of the bracket body 210 to form a relative abutting force to limit the bracket body 210 from shaking in one direction of the plane where it is located, thereby realizing the positioning pre-installation of both sides of the bracket body 210.

[0087] like Figure 2 、 Figure 3As shown, the door panel body 120 also includes an integrally formed thin plate structure 121, which is a sheet metal component and has a rectangular shape. A fixing seat 122 is disposed on the thin plate structure 121. The fixing seat 122 also includes a mounting seat 1222, with a first stopper 1221 protruding from the mounting seat 1222. The number of fixing seats 122 and their positions on the thin plate structure 121 are determined based on the size of the bracket body 210 to accommodate pre-installation of bracket bodies 210 of different sizes.

[0088] like Figure 18 As shown, the first limiting portion 1221 is a bent structure, with the bending direction of the first limiting portion 1221 facing the corresponding mounting portion of the bracket body 210. The first limiting portions 1221 of the two fixing seats 122, which form a relative abutment force, are bent in opposite directions to limit the two opposite outer sides of the bracket body 210. A side wall of the bracket body 210 extends into the cavity formed by the bent structure of the first limiting portion 1221 and the surface of the mounting seat 1222, restricting three surfaces on one side of the bracket body 210. That is, the first limiting portions 1221 of at least two fixing seats 122, which form a relative abutment force, respectively engage the two opposite side walls of the bracket body 210 to restrict movement of the bracket body 210 in two directions, including limiting rocking of the bracket body 210 in the plane of the thin plate structure 121 and limiting movement of the bracket body 210 away from the thin plate structure 121.

[0089] Furthermore, the inner wall of the bent structure of the first limiting portion 1221 completely presses against the outer wall of the bracket body 210 away from the thin plate structure 121, that is, the inner wall of the cavity formed by the bent structure of the first limiting portion 1221 and the surface of the mounting seat 1222 is tightly attached to the outer wall of the bracket body 210 away from the thin plate structure 121, so as to firmly limit the movement of the bracket body 210 in the direction away from the thin plate structure 121.

[0090] An assembly gap is provided between the inner wall of the curved structure of the first limiting portion 1221 and the outer wall of the bracket body 210, allowing the bracket body 210 to move slightly between the two opposing fixing seats 122 and in the direction of the two opposing fixing seats 122. After the bracket body 210 is inserted into the curved structure of the fixing seat 122, a slight gap is left between the inner wall of the fixing seat 122 on the side opposite the bracket body 210 and the bracket body 210. This prevents the fixing seat 122 from being too close to the bracket body 210, which would increase the difficulty of installation. Due to the curved structure of the fixing seat 122, the two sides of the bracket body 210 are constrained within the curved structure of the fixing seat 122, allowing only slight left and right movement, which does not affect the positioning and pre-installation.

[0091] like Figure 2 、 Figure 4As shown, the thin plate structure 121 is provided with a hole 1211; a first limiting portion 1221 extends into the hole 1211, and a mounting seat 1222 is connected to an outer wall of the thin plate structure 121. The mounting seat 1222 completely covers the hole 1211 to seal the hole 1211, facilitating subsequent foaming and preventing foaming overflow. Furthermore, the inner contour of the hole 1211 is larger than the outer contour of the first limiting portion 1221, so that the first limiting portion 1221 can smoothly extend into the hole 1211. The mounting seat 1222 is provided with a plurality of third through holes 12222, and the thin plate structure 121 is provided with fourth through holes 1215 corresponding to the positions of the third through holes 12222. In one embodiment, the fixing seat 122 is connected to the thin plate structure 121 by rivets passing through the fourth through holes 1215 and the third through holes 12222 in sequence. In another embodiment, the fixing base 122 is detachably connected to the thin plate structure 121 by screws passing through the fourth through hole 1215 and the third through hole 12222 in sequence.

[0092] The fixing seat 122 is a plastic part with a certain elasticity, which is convenient for pre-installing the bracket body 210 and is not easily damaged.

[0093] like Figure 2 、 Figure 16 As shown, a plurality of fixing seats 122 are arranged in two columns; the first limiting portions 1221 of the fixing seats 122 in the same column have the same bending direction, while the first limiting portions 1221 of the fixing seats 122 in different columns have opposite bending directions. In one embodiment, the fixing seats 122 are arranged in two columns and several rows, and the two oppositely arranged fixing seats 122 in different columns are on the same horizontal line. The fixing seats 122 are arranged regularly to position and pre-install the bracket body 210. In another embodiment, the two oppositely arranged fixing seats 122 in different columns are not on the same horizontal line, but are staggered in the longitudinal direction, which can achieve positioning and pre-installation of the bracket body 210. However, due to the irregular arrangement of the fixing seats 122, the installation of the fixing seats 122 is slightly inconvenient. Furthermore, the fixing seats 122 are arranged in pairs on the thin plate structure 121.

[0094] In one embodiment, if Figure 2 、 Figure 16 As shown, there are three pairs of fixing seats 122, which are arranged opposite each other at the top, bottom, and between the top and bottom ends of a surface of the thin plate structure 121. The two oppositely arranged fixing seats 122 in different rows are on the same horizontal line to respectively position and pre-install several parts of the bracket body 210.

[0095] In one embodiment, the direction of the row of the plurality of fixing seats 122 is parallel to the longitudinal direction of the thin plate structure 121; Figure 18As shown, the first limiting portion 1221 is bent in an "L" shape, including a first bent edge 12211 and a second bent edge 12212. The first bent edge 12211 is fixed on the mounting seat 1222. The first bent edge 12211 and the second bent edge 12212 are perpendicular to each other. The first bent edge 12211 is parallel to the longitudinal direction of the thin plate structure 121, so that the first limiting portion 1221 of the relatively arranged fixing seat 122 limits the longitudinal movement of the bracket body 210 and the movement in the direction away from the thin plate structure 121.

[0096] like Figure 18 As shown, the mounting seat 1222 is provided with a positioning column 12221, and the thin plate structure 121 is provided with a positioning hole 1212 corresponding to the position of the positioning column 12221. When installing the fixing seat 122, the positioning column 12221 is aligned and extended into the corresponding positioning hole 1212 to achieve the positioning pre-installation of the fixing seat 122 and the thin plate structure 121, which is convenient for installation.

[0097] like Figure 2 As shown, the door structure 121 also includes a first side extrusion strip 170 and a second side extrusion strip 180, respectively fixed to opposite sides of the thin plate structure 121. The outer sides of the first side extrusion strip 170 and the outer sides of the second side extrusion strip 180 are respectively connected to the first side trim strip 150 and the second side trim strip 160, which respectively form the side frames of the door body and frame. The first side extrusion strip 170 has a first retaining groove 171, and the second side extrusion strip 180 has a second retaining groove 181. The first retaining groove 171 and the second retaining groove 181 face each other to respectively retain the ends of the thin plate structure 121.

[0098] like Figure 2 、 Figure 3 、 Figure 19 、 Figure 20 As shown, thin plate structure 121 is provided with a second bent portion 1214 on each side for thickening. In one embodiment, thin plate structure 121 is a sheet metal component that is easily bent. After bending both sides of thin plate structure 121, the bent edges are attached to a surface of thin plate structure 121 away from bracket body 210. The thickening of thin plate structure 121 on both sides provides a certain thickness to facilitate engagement with first and second slots 171, 181. This prevents the first and second slots 171, 181 from becoming too narrow due to the thickness of thin plate structure 121, which increases the difficulty of alignment.

[0099] like Figure 19 、 Figure 20As shown, since the first side extrusion strip 170 and the second side extrusion strip 180 are respectively installed on both sides of the thin plate structure 121 that undergoes the bending and thickening process, if the fixed connection between the first side extrusion strip 170 or the second side extrusion strip 180 and the thin plate structure 121 is at the bending edge of the thin plate structure 121, then the second bending portion 1214 on this side must be provided with a second notch 12141 for making way for installation; if the fixed connection between the first side extrusion strip 170 and the second side extrusion strip 180 on both sides and the thin plate structure 121 is at the corresponding bending edge of the thin plate structure 121, then the second bending portion 1214 on both sides must be provided with a second notch 12141 for making way for installation. That is, the second bending portion 1214 on at least one side is provided with a second notch 12141 for making way for installation. In one embodiment, the first side extrusion strip 170 and / or the second side extrusion strip 180 are connected to the thin plate structure 121 by rivets. The rivets are inserted into the corresponding through holes from the side where the bracket body 210 is located and then fixed. The diameter of the rivet will increase at the end away from the bracket body 210. In order to avoid the bent edges on both sides of the thin plate structure 121 blocking the increase in diameter after the rivet is fixed, the size of the second notch 12141 is based on not affecting the increase in diameter of the local part when the rivet is fixed.

[0100] like Figure 2 As shown, the first side trim 150 is provided with a third clamping groove 151 for clamping the two ends of the first side extrusion strip 170. The first side extrusion strip 170 is closely attached to the inner walls of the three sides of the third clamping groove 151 to limit the forward and backward movement of the first side extrusion strip 170. The second side trim 160 is provided with a fourth clamping groove 161 for clamping the two ends of the second side extrusion strip 180. The second side extrusion strip 180 is closely attached to the inner walls of the three sides of the fourth clamping groove 161 to limit the forward and backward movement of the second side extrusion strip 180.

[0101] like Figure 2 、 Figure 5 、 Figure 6 As shown, the first side extrusion strip 170 and the second side extrusion strip 180 are both asymmetrical structures to prevent fooling around, so that the installer can confirm which side of the door panel body 120 to install them on.

[0102] like Figure 2 、 Figure 3As shown, the thin plate structure 121 is provided with a first foolproof portion 1213 for indicating the installation direction, for distinguishing the top or bottom direction of the thin plate structure 121 and / or for distinguishing the front or back side of the thin plate structure 121. In one embodiment, the first foolproof portion 1213 is a triangular shape, the sharp corner of the triangle is used to indicate the top or bottom direction of the thin plate structure 121, and the side of the triangle is used to indicate the front or back side of the thin plate structure 121. In another embodiment, the first foolproof portion 1213 is a triangular hole, the sharp corner of the triangle is used to indicate the top or bottom direction of the thin plate structure 121, but does not have the function of indicating the front or back side of the thin plate structure 121.

[0103] like Figure 2 、 Figure 4 As shown, hole 1211 is provided with a second anti-mumbling portion 12111 for indicating the installation direction of the fixing seat 122. In one embodiment, the first position-limiting portion 1221 is a bent structure, and the second anti-mumbling portion 12111 is used to indicate the bending direction of the first position-limiting portion 1221 when the fixing seat 122 is installed, thereby facilitating assembly and improving assembly efficiency. In one embodiment, the second anti-mumbling portion 12111 is a corner structure within hole 1211. The corner structures within the two holes 1211 corresponding to the two oppositely disposed fixing seats 122 are positioned relative to each other, thereby indicating the relative bending direction of the bending structures of the two oppositely disposed fixing seats 122. Furthermore, the first limiting portion 1221 is provided with a third anti-foolproofing portion 12213 corresponding to the second anti-foolproofing portion 12111. The shape of the third anti-foolproofing portion 12213 is the same as that of the second anti-foolproofing portion 12111, that is, it is a corner structure on the first limiting portion 1221. The corner structure on the first limiting portion 1221 matches the corner structure on the hole 1211 to indicate the installation direction of the fixing seat 122 relative to the corresponding hole 1211.

[0104] In one embodiment, if Figure 22 As shown, the bracket body 210 is a frame structure, and the display screen 220 is fixed in the frame of the bracket body 210.

[0105] Furthermore, the bracket body 210 includes a fixed bracket 212 and an extended bracket; wherein,

[0106] The fixed bracket 212 is a frame structure, and the display screen 220 of the display screen assembly 200 is fixed within the fixed bracket 212 frame. The fixed bracket 212 is connected to at least one extension bracket to form a mounting structure that matches the foam door assembly 100. The size of the bracket body 210 can be changed by changing the number of extension brackets and / or changing the size of one or more extension brackets.

[0107] It should be understood that the above-mentioned installation structure of the foam door assembly 100 includes changing the size of the bracket body 210 to form different installation structures for matching the foam door assembly 100 .

[0108] In one embodiment, the fixed bracket 212 and the extended bracket are spliced ​​together and are easy to disassemble.

[0109] In one embodiment, the fixed bracket 212 is seamlessly connected to the extended bracket, and the fixed bracket 212 and the extended bracket are tightly abutted against each other, making them less likely to shake, thereby preventing a gap between the fixed bracket 212 and the extended bracket from affecting the subsequent bonding of the transparent panel 230 of the display assembly 200 .

[0110] The splicing method includes horizontal splicing, vertical splicing or a combination of the two. The multiple extension brackets can be the same or different; that is, the structures and sizes of the multiple extension brackets can be the same or different, depending on production requirements.

[0111] In one embodiment, if Figure 3 As shown, a plurality of expansion brackets are connected to each other to form a whole, and then connected to the fixed bracket 212.

[0112] In one embodiment, several extension brackets and fixed brackets 212 are spliced ​​together longitudinally. Changing the size of any one or more of the remaining extension brackets and / or the number of extension brackets can change the longitudinal dimension of the bracket body 210 formed by the longitudinal splicing of the brackets. Similarly, the transverse dimension of the bracket body 210 formed by the transverse splicing of several extension brackets and fixed brackets 212 can be changed. In one embodiment, the bracket body 210 is formed by a combination of transverse and longitudinal splicing. Changing the size of any one or more of the extension brackets and / or the number of the extension brackets can change the longitudinal dimension and / or the longitudinal dimension of the bracket body 210. In other words, during actual production, if the display screen 220 size remains unchanged, the size of the fixed bracket 212 remains unchanged, eliminating the need for re-production. To accommodate different sizes of home appliance doors, the size of any one or more of the extension brackets and / or the number of extension brackets can be changed. Furthermore, the splicing connection allows for easy disassembly, a simple structure for the extension brackets, a short production process, and low replacement costs, making it easy to adjust the size of the bracket body 210.

[0113] like Figure 1 As shown, the fixed bracket 212 and the outer contours of the transparent panel 230 of the plurality of extended brackets facing the display screen assembly 200 are in the same plane; Figure 3As shown, the fixed bracket 212 and the outer contours of the transparent panel 230, facing away from the display screen assembly 200, are coplanar with the outer contours of the several extended brackets. Specifically, the front and back surfaces of the bracket body 210 are flat, facilitating the engagement of the bracket body 210 with the door panel 120 of the foam door assembly 100 and the adhesion between the transparent panel 230 and the bracket body 210. In one embodiment, the outer contour of the transparent panel 230, facing the display screen assembly 200, is flush with the outer contours of the first and second side moldings 150, 160 of the foam door assembly 100, ensuring a stable fixation of the transparent panel 230.

[0114] In one embodiment, the fixed bracket 212 is connected to the extension bracket via a buckle, which is engaged with a slot via the buckle, and the fixed bracket and the extension bracket or the plurality of extension brackets are detachable.

[0115] In one embodiment, the fixed bracket 212 is connected to the extension bracket by a fastener, and the fixed bracket and the extension bracket or the plurality of extension brackets are fixedly connected and firmly connected.

[0116] like Figure 22 、 Figure 23As shown, the spliced ​​fixed bracket and the extension bracket or brackets are fixedly connected via a connecting structure 218 to form a stable, integrated bracket body 210, facilitating subsequent installation of the appliance door. In one embodiment, the connecting structure 218 includes a first connecting portion 2181 and a second connecting portion 2182 that interlock with each other. The first connecting portion 2181 and the second connecting portion 2182 are respectively disposed on opposing outer walls of the two spliced ​​brackets. The first connecting portion 2181 is a positioning protrusion, and the second connecting portion 2182 is a positioning groove that restricts the movement of the first connecting portion 2181 in at least four directions. The cross-sections of the first connecting portion 2181 and the second connecting portion 2182 are both trapezoidal. The first connection part 2181 and the second connection part 2182 are respectively provided with a through hole, and the second connection part 2182 in the form of a positioning groove is provided with a side wall along the extension direction of the extension bracket to form a side wall structure forming a through hole. Furthermore, the extended side wall is flush with a surface of the extension bracket; the first connection part 2181 and the second connection part 2182 are fixedly connected by screws in the direction facing or back to the transparent panel 230. The first connection part 2181 and the second connection part 2182 play the role of positioning and fixing at the same time, and do not affect the flatness of the side of the bracket body 210 facing or back to the transparent panel 230. Furthermore, the first connection part 2181 in the form of a positioning protrusion gradually expands in the extended extension direction, and the second connection part 2182 in the form of a positioning groove is an opening away from or close to the door panel body. The first connection part 2181 is placed into the second connection part 2182 in the form of a positioning groove from the opening of the second connection part 2182. The first connection part 2181 is not easy to detach from the second connection part 2182, which is convenient for subsequent fixing by screws. In one embodiment,

[0117] Furthermore, the fixed bracket 212 and the connected extended bracket are in contact with the positioning protrusion via the positioning groove. Figure 22 、 Figure 24 As shown, the fixed bracket 212 and the connected extension bracket are first pre-installed by abutting to reduce the difficulty of assembly. Furthermore, the positioning groove abuts against the positioning protrusion. The positioning protrusion gradually narrows along its extension direction. In one embodiment, the cross-section of the positioning groove and the cross-section of the positioning protrusion are both triangular, and the triangular corner of the positioning protrusion is first inserted into the positioning groove until the outer contour of the part where the positioning protrusion is inserted into the positioning groove is in close contact with the inner contour of the positioning groove; since the triangular corner of the positioning protrusion is small in size, it can be quickly inserted into the positioning groove, and finally the positioning pre-installation is achieved. The inner contour of the positioning groove wraps the outer contour of the positioning protrusion inserted into the positioning groove, so that after the positioning protrusion is inserted into the positioning groove, it is firmly fixed without shaking left and right. In one embodiment, as Figure 22As shown, the bracket body 210 includes three brackets connected longitudinally in sequence, namely, two extension brackets, including a first extension bracket 211 and a second extension bracket 213. Specifically, the bracket body 210 includes the first extension bracket 211, a fixed bracket 212, and a second extension bracket 213 connected longitudinally in sequence. The display screen 220 is fixed within the fixed bracket 212, which has a frame structure. The longitudinal dimension of the bracket body 210 can be changed by adding or removing the first extension bracket 211 and / or the second extension bracket 213, or by changing the size of the first extension bracket 211 and / or the second extension bracket 213. Furthermore, manufacturers can set several sizes for the standard bracket body 210, namely, the bracket body 210 includes a first expansion bracket 211, a fixed bracket 212, and a second expansion bracket 213, which are sequentially connected; or, the bracket body 210 includes a first expansion bracket 211 and a fixed bracket 212, which are sequentially connected; or, the bracket body 210 includes a fixed bracket 212 and a second expansion bracket 213, which are sequentially connected; or, the bracket body 210 includes a fixed bracket 212 and a second expansion bracket 213, which are sequentially connected. By adding or removing the first expansion bracket 211 and / or the second expansion bracket 213, the size of the bracket body 210 can be quickly expanded according to production needs. Furthermore, the first expansion bracket 211 and the second expansion bracket 213 can be the same or different.

[0118] In one embodiment, if Figures 22 to 24 As shown, the outer wall of the first extension bracket 211 facing the fixed bracket 212 is provided with a fifth abutting portion 2111, the outer wall of the second extension bracket 213 facing the fixed bracket 212 is provided with an eighth abutting portion 2131, and the outer walls of the fixed bracket 212 are provided with a sixth abutting portion 2121 and a seventh abutting portion 2122, respectively abutting against the fifth abutting portion 2111 and the eighth abutting portion 2131. Furthermore, the fifth abutting portion 2111 and the eighth abutting portion 2131 are triangular positioning protrusions; the sixth abutting portion 2121 and the seventh abutting portion 2122 are triangular positioning grooves that match the fifth abutting portion 2111 and the eighth abutting portion 2131, respectively.

[0119] Furthermore, a third mounting portion 217 is provided at the top and / or bottom of the bracket body 210. The third mounting portion 217 has mounting holes for securely connecting to the upper end cover body 110 and / or the lower end cover body 130 via screws, further securing the bracket body 210 to the foam door assembly 100 and stabilizing the splicing connection between the multiple brackets. As shown in the figure, the third mounting portion 217 is provided at the bottom end of the bracket body 210 for secure connection to the lower end cover body 130.

[0120] like Figure 1 、 Figure 2As shown, in one embodiment, the door frame of the foam door assembly 100 includes an upper end cover body 110 and a lower end cover body 130, which are respectively used to form the top structure and bottom structure of the door frame; the upper end cover body 110 and the lower end cover body 130 respectively press the top and bottom ends of the bracket body 210.

[0121] like Figure 1 、 Figure 7 、 Figure 11 As shown, in one embodiment, the upper end cover body 110 includes a first cover body 111 and a second cover body 112 fixed to the top of the first cover body 111. The second cover body 112 is provided with a first bending portion 1123, which is also used to close the assembly gap between the transparent panel 230 of the display screen assembly 200 and the first cover body 111, so that a sealing structure is formed between the transparent panel and the door frame of the foam door assembly 100 to prevent dust accumulation. Furthermore, the two sides of the first bending portion 1123 are respectively attached to the inner side of the transparent panel 230 of the display screen assembly 200 and one side of the first cover body 111. The first bending portion 1123 is provided with a first abutting portion 1125 relative to one end of the bracket body 210, which abuts against one end of the bracket body 210 to press the top of the bracket body 210.

[0122] In one embodiment, if Figure 2 As shown, a plurality of second abutting portions 1311 are provided at one end of the lower end cover body 130 relative to the bracket body 210 to press the bottom end of the bracket body 210 .

[0123] The bracket body 210 abuts against the upper end cover body 110 and the lower end cover body 130, and further abuts against the positioning protrusions through the positioning grooves. The positioning protrusions extend into the positioning grooves and are positioned by the positioning grooves to achieve splicing connection between adjacent brackets, or to achieve positioning connection between the upper end cover body 110 and the lower end cover body 130 to the top and bottom ends of the bracket body 210, respectively.

[0124] like Figure 14 、 Figure 15 As shown, the positioning protrusion gradually narrows along its extension direction. In one embodiment, the cross-sections of the positioning groove and the positioning protrusion are both triangular. The triangular corner of the positioning protrusion first extends into the positioning groove until the outer contour of the portion where the positioning protrusion extends into the positioning groove closely matches the inner contour of the positioning groove. Due to the small size of the triangular corner of the positioning protrusion, it can be quickly inserted into the positioning groove, ultimately achieving positioning pre-installation.

[0125] The inner contour of the positioning groove wraps the outer contour of the positioning protrusion extending into the positioning groove, so that after the positioning protrusion extends into the positioning groove, it is firmly fixed and will not shake left and right.

[0126] like Figure 1As shown, in one embodiment, the second abutting portion 1311 and the third abutting portion 215 are positioning grooves, and the first abutting portion 1125 and the fourth abutting portion 216 are positioning protrusions. The first abutting portion 1125 of the upper end cover body 110 is extended into the third abutting portion 215 at the top end of the bracket body 210, and the second abutting portion 1311 of the lower end cover body 130 is wrapped around the fourth abutting portion 216 at the bottom end of the bracket body 210, thereby pre-positioning the top and bottom ends of the bracket body 210 and limiting the longitudinal movement of the bracket body 210. In addition, due to the cooperation between the positioning groove and the positioning protrusion, the lateral movement of the bracket body 210 is further limited. By snapping the positioning protrusion into the positioning groove for abutment, the first abutting portion 1125 and the second abutting portion 1311 are respectively pressed against the top and bottom ends of the bracket body 210, while also providing positioning auxiliary installation functions, reducing the difficulty of assembly. A third mounting portion 217 protrudes from the lower end of the bracket body 210 and extends into a groove in a corresponding mounting portion of the lower end cover body 130. Screws are inserted sequentially through the mounting holes in the groove in the mounting portion of the lower end cover body 130 and the mounting holes in the third mounting portion 217 to securely connect the bracket body 210 to the lower end cover body 130, thereby limiting downward longitudinal movement of the bracket body 210. The first cover 111 of the upper end cover body 110 is securely connected to the door panel body 120. The bracket body 210 engages with the corresponding first limiting portion 1221 of the door panel body 120 from the top side of the door panel body 120. The first abutting portion 1125 of the second cover 112 abuts the third abutting portion 215 at the top of the bracket body 210. Screws securely connect the first cover 111 to the second cover 112, thereby limiting upward longitudinal movement of the bracket body 210.

[0127] like Figures 22 to 24 、 Figure 14 As shown, at least one engaging structure 214 is provided on opposite sides of the bracket body 210 to engage with the first stopper 1221 on the door panel body 120. Furthermore, at least one engaging structure 214 is provided on opposite sides of the fixed bracket 212 to securely fix the fixed bracket 212 to the door panel body 120, preventing it from separating from the door panel body 120 and thereby protecting the display screen 220. Furthermore, a engaging structure 214 is provided on opposite sides of the fixed bracket 212 and the plurality of extension brackets to securely fix the bracket body 210 to the door panel body 120.

[0128] like Figure 22 、 Figure 24As shown, the snap-fit ​​structure 214 includes a snap-fit ​​portion 2141 and a second limiting portion 2142. The snap-fit ​​portion 2141 extends into the cavity formed by the bent first limiting portion 1221 and the thin surface of the door panel body 120. The first limiting portions 1221 on either side of the bracket body 210 are bent in opposite directions to limit the lateral movement of the bracket body 210 and movement away from the door panel body 120. The second limiting portion 2142 abuts against the outer wall of the first limiting portion 1221 to prevent the snap-fit ​​portion 2141 from disengaging from the first limiting portion 1221, thereby achieving snap-fit. In one embodiment, the snap-fit ​​structures 214 are provided on both opposing outer walls of the bracket body 210. The snap-fit ​​structures 214 on the same side wall of the bracket body 210 may have the same or different structures or dimensions.

[0129] like Figures 22 to 24 As shown, in one embodiment, the bracket body 210 includes a first extension bracket 211, a fixed bracket 212, and a second extension bracket 213 that are spliced ​​and connected in sequence longitudinally; the number of the clamping structures 214 is six, and a clamping structure 214 is provided on both sides of the first extension bracket 211, the fixed bracket 212, and the second extension bracket 213 respectively. The first clamping structure 2143, the second clamping structure 2144, and the third clamping structure 2145 on the first extension bracket 211, the fixed bracket 212, and the second extension bracket 213 are slightly different in structure and size, but the first clamping structure 2143, the second clamping structure 2144, and the third clamping structure 2145 have the same clamping effect on the corresponding first limiting portion 1221.

[0130] Furthermore, after several snap-in portions 2141 respectively extend into the cavities formed by the corresponding first limiting portions 1221 and the thin plate surface of the door panel body 120, the corresponding second limiting portions 2142 just rest against the outer walls of the corresponding first limiting portions 1221, so that the several first limiting portions 1221 on the door panel body 120 simultaneously apply a force toward the second limiting portions 2142 to the bracket body 210 to achieve a stable snap connection.

[0131] The snap-in portion 2141 is gradually narrowed and thinned in the direction away from the second limiting portion 2142, so that the snap-in portion 214 can smoothly extend into the cavity formed by the first limiting portion 1221 and the thin plate surface of the door panel body 120, so as to quickly achieve snap-in.

[0132] Furthermore, an assembly gap is provided between the outer wall of the snap-in portion 2141 of the bracket body 210 and the inner wall corresponding to the first limiting portion 1221, so that the snap-in portion 2141 can smoothly extend into the cavity formed by the first limiting portion 1221 and the thin plate surface of the door panel body 120. The snap-in structure 214 can move slightly left and right in the cavity formed by the corresponding first limiting portion 1221 and the thin plate surface of the door panel body 120, which is convenient for snapping in without affecting the effect of the first limiting portion 1221 on limiting the lateral movement of the bracket body 210 and the movement in the direction away from the door panel body 120.

[0133] like Figure 1 、 Figure 22 、 Figure 23 As shown, at least two opposite inner walls of the frame of the fixed bracket 212 are convexly provided with a ninth abutting portion 2123 for abutting against the back of the display screen 220, and the thickness of the ninth abutting portion 2123 is less than the thickness of the frame of the fixed bracket 212. The outer contour of the ninth abutting portion 2123 and the outer contour of the display screen 220 are both located in the corresponding bracket frame. In one embodiment, the cross-section of the display screen 220 and the inner contour of the bracket frame for fixing the display screen are both rectangular; a ninth abutting portion 2123 is respectively provided at both ends of an inner wall of the frame of the fixed bracket 212, and a ninth abutting portion 2123 is respectively provided on the other two inner walls of the frame of the fixed bracket 212 near the corners of the frame, and the four ninth abutting portions 2123 are respectively abutted against the four corners of an outer surface of the display screen 220 to firmly abut against the display screen 220. As shown Figure 1 、 Figure 22 As shown, in one embodiment, the ninth abutting portion 2123 is disposed on the inner wall of the frame of the fixing bracket 212 .

[0134] The outer surface of the bracket body 210 facing the transparent panel 230 protrudes from or is flush with the outer surface of the first limiting portion 1221 facing the transparent panel 230, so as to prevent the outer surface of the first limiting portion 1221 facing the transparent panel 230 from protruding from the outer surface of the bracket body 210 facing the transparent panel 230, thereby affecting the fit between the transparent panel 230 adhered to the outside of the bracket body 210 and the frame of the foam door body assembly 100 when the display screen assembly 200 is clamped on one side of the foam door body assembly 100.

[0135] like Figure 22 、 Figure 14As shown, the bracket body 210 is provided with clearance portions 219 on both sides to allow the bracket body 210 to engage with the first limiting portion 1221. The clearance portions 219 on both sides of the bracket body 210 are aligned with the corresponding first limiting portion 1221 on the door panel body 120. The bracket body 210 is moved downward to engage, thereby achieving the engagement between the bracket body 210 and the door panel body 120. In one embodiment, the number of the engaging structures 214 and the number of the first limiting portions 1221 are both six, and the number of the clearance portions 219 on both sides of the bracket body 210 is also six, so as to allow the engaging structure 214 to engage with the first limiting portion 1221 from above.

[0136] In one embodiment, if Figure 7 、 Figure 11 As shown, the first cover 111 is provided with a drainage groove 1111. A drainage outlet 11111 is located on one side of the drainage groove 1111. The bottom surface of the drainage groove 1111 is sloped, gradually decreasing in depth toward the drainage outlet 11111. The drainage outlet 11111 is located at the lower end of the slope to guide water to the drainage outlet 11111. The second cover 112 seals the sides of the drainage groove 1111, leaving a gap corresponding to the drainage outlet 11111 to allow drainage from the drainage groove 1111. Because water tends to flow downward, the drainage groove 1111 promptly removes any water that may accumulate on the upper surface of the upper cover body 110.

[0137] like Figure 7 、 Figure 10 As shown, the first cover body 111 is provided with a second groove 1113 for accommodating the wiring terminal and / or the knocking module 113, and the second groove 1113 is provided with a through groove 11131 for the wiring harness to pass through; the first cover body 111 is also provided with a first through hole 11151 for being pivotally connected to the home appliance case; the wiring harness of the display screen assembly of the home appliance door body is connected to the wiring terminal after passing through the through groove 11131, and the wiring harness in the home appliance case is connected to the wiring terminal after passing through the first through hole 11151 and the through groove 11131 in turn.

[0138] like Figure 7 、 Figure 10 As shown, the second groove 1113 is provided with a first fixing portion 11133, and the knocking module 113 is fixed to the first fixing portion 11133. In one embodiment, the first fixing portion 11133 is a threaded hole with a closed bottom; the knocking module 113 is provided with a corresponding fixing hole, and a screw is passed through the fixing hole and screwed into the threaded hole to fix the knocking module 113. The knocking module 113 is electrically connected to the main control board disposed inside the door of the home appliance, and can be formed to identify whether the user is knocking on the door of the home appliance and instruct the home appliance to respond according to the user's knocking operation. For example, the door of the home appliance can be opened or the lighting of the home appliance can be turned on by the user's knocking action.

[0139] The knock module 113 includes a knock sensor that can receive vibrations generated by a user knocking on the appliance door to sense the vibration signal generated by the knocking. The knock module 113 also includes a control unit electrically connected to the knock sensor. The control unit can be directly installed on the main control board inside the appliance door or installed separately to receive the vibration information transmitted by the knock sensor and determine whether it is a preset knock vibration. If it is a preset knock vibration, it will issue a command to the appliance door to respond; if it is not a preset knock vibration, the appliance door will not respond.

[0140] The first cover body 111 and the second cover body 112 are connected by a plurality of screws; the second cover body 112 is provided with a plurality of second through holes 1122, and the first cover body 111 is provided with a plurality of threaded holes 1116 corresponding to the second through holes 1122, and the bottom of the threaded holes 1116 is closed. The plurality of threaded holes 1116 and the plurality of second through holes 1122 correspond to each other one by one for screws to pass through for screw connection.

[0141] like Figure 7 、 Figure 8 As shown, the first cover 111 is provided with a first groove 1112; the drainage groove 1111 and the second groove 1113 are respectively provided in the first groove 1112, and the drainage port 11111 is provided on the side wall of the first groove 1112; the second cover 112 covers the first groove 1112; wherein,

[0142] The outer wall of the second groove 1113 corresponding to the inner area of ​​the first groove 1112 extends upward to form a diversion cavity 1114 between the inner wall of the first groove 1112; the diversion cavity 1114 is connected to the drainage groove 1111;

[0143] At least one screw connection between the first cover 111 and the second cover 112 corresponds to the diversion cavity 1114 , so that water on the outer wall of the first cover 111 enters the diversion cavity 1114 from the screw connection and then flows into the drainage groove 1111 .

[0144] The first threaded hole 11161 located in the diversion cavity 1114 is an ordinary threaded hole, and the second threaded hole 11162 located in the second groove 1113 for placing the wiring terminal and / or the knocking module 113 can be a threaded hole made of micro-expanding material or the threaded hole is waterproofed, so that after the screw is screwed into the second threaded hole 11162, the screw and the second threaded hole 11162 form a sealed connection structure, and the water on the outer wall of the upper end cover body 110 will not fall into the second groove 1113, but will only fall into the diversion cavity 1114 in a targeted manner to divert and drain water, thereby achieving effective and safe drainage.

[0145] like Figure 7As shown, the first cover 111 is provided with a deflector 1115 corresponding to the drain outlet 11111. The height of the deflector 1115 is lower than the bottom of the drain outlet 11111. This allows water accumulated in the drainage trough 1111 to drain along the drain outlet 11111 onto the deflector 1115, and then fall along the door sidewall or door seal near the deflector 1115. A first through hole 11151 is provided on the deflector 1115. The drainage trough 1111 and deflector 1115 are located near the pivotal connection between the appliance door and the appliance housing. Water falls along the door sidewall or door seal near the deflector 1115, creating a concealed and safe drainage route that does not affect the user experience.

[0146] A sidewall of the second groove 1113 overlaps with a sidewall of the first groove 1112, thereby increasing the space in the second groove 1113 to accommodate the terminal block and / or the knock module 113. The second groove 1113 is rectangular, with three outer walls and the interior area of ​​the first groove 1112 forming a diversion cavity 1114, and one sidewall overlapping with a side of the first groove 1112.

[0147] The inner wall of the first groove 1112 is provided with a mounting platform 11121 for placing the second cover 112, so that the outer surface of the second cover 112 is flush with the outer surface of the first cover 111. In other words, one surface of the second cover 112 is in contact with the mounting platform 11121, and the side wall of the second cover 112 located within the first groove 1112 is in contact with the inner wall of the first groove 1112. The outer surface of the second cover 112 is flush with the outer surface of the first cover 111, so that the upper surface of the upper end cover body 110 is smooth and beautiful.

[0148] like Figure 8 As shown, a guide protrusion 1121 is provided on the inner surface of the second cover 112 , and a guide groove 11211 is provided on the guide protrusion 1121 ; the guide protrusion 1121 corresponds to the guide cavity 1114 to guide water to flow into the drainage groove 1111 along the guide cavity 1114 .

[0149] In one embodiment, if Figure 8 As shown, one end of the diversion protrusion 1121 is connected to the outer wall of the second through hole 1122, which is located away from the drainage groove 1111 and corresponds to the diversion cavity 1114. This guides water from the outer surface of the second cover 112 to preferentially flow from the connection between the second cover 112 and the second through hole 1122, which is located away from the drainage groove and corresponds to the diversion cavity 1114, and then flow along the diversion cavity 1114 to the drainage groove 1111, thereby dredging the flow of water and preventing excessive water from accumulating on the surface of the first cover 111. The drainage groove 1111 is located near the pivotal connection between the home appliance door and the home appliance housing. The second through hole 1122, which is located away from the drainage groove 1111 and corresponds to the diversion cavity 1114, and the drainage groove 1111 are respectively located on both sides of the second groove 1113.

[0150] like Figure 9As shown, the diversion protrusion 1121 extends into the diversion cavity 1114 and does not contact the bottom surface of the diversion cavity 1114, leaving space for water to flow along the diversion cavity 1114. Since household appliances are usually of a certain height, the water accumulated on the upper end cover body 110 is not large in quantity, and the screw connection between the first cover body 111 and the second cover body 112 is relatively tight. Therefore, the water will enter the first threaded hole 11161 in the diversion cavity 1114 in the form of water droplets or small streams along the screw connection between the first cover body 111 and the second cover body 112. The water overflows from the first threaded hole 11161 and, under the action of its own gravity, enters the drainage groove 1111 along the diversion groove 11211 provided on the diversion protrusion 1121 and is discharged. Due to the diversion function of the diversion groove 11211, water is easily diverted along the diversion groove 11211, and the water on the upper end cover body 110 easily flows downward from the second through hole 1122 connected to the diversion protrusion 1121, and then enters the corresponding area of ​​the diversion cavity 1114 corresponding to the second through hole 1122. Further, for the sake of clarity, as shown in FIG. Figure 7 、 Figure 10 As shown, the first guide cavity 11141 is far away from the drainage groove 1111, the third guide cavity 11143 is close to the drainage groove 1111, and the second guide cavity 11142 is located between the first guide cavity 11141 and the third guide cavity 11143. Water can easily flow in from the second through hole 1122 connected to the guide protrusion 1121, and flow along the guide groove 11211 from the first guide cavity 11141, the second guide cavity 11142, and the third guide cavity 11143 in turn, and finally flow into the drainage groove 1111.

[0151] like Figure 8 As shown, the diversion protrusion 1121 is provided with a first extension portion 11212 in a bent shape to prevent the water in the diversion cavity 1114 from entering the threaded hole 1116 located in the diversion cavity 1114 and close to the drain groove 1111. Figure 7 、 Figure 8 As shown, the two first threaded holes 11161 in the third guide cavity 11143 near the drainage groove 1111 are partially blocked by the first extension portion 11212 between the drainage groove 1111. If water accumulates on the surface of the third guide cavity 11143, the water will flow to a lower place, that is, into the drainage groove 1111. Even if there is too much water on the surface of the third guide cavity 11143, due to the partial obstruction of the first extension portion 11212 and the different sizes of the spaces on both sides of the first extension portion 11212, the accumulated water on the surface of the third guide cavity 11143 is not easy to flow to the two first threaded holes 11161, but flows into the drainage groove 1111; if water on the outer surface of the upper end cover body 110 flows into the two first threaded holes 11161 in the third guide cavity 11143 and overflows, since there is still a gap between the first extension portion 11212 and the surface of the third guide cavity 11143, the water flows through the gap and flows into the drainage groove 1111 to achieve drainage.

[0152] like Figure 10 As shown, a first baffle 11112 and a second baffle 11113 are provided in the drainage trough 1111 near the drainage outlet 11111, which are positioned in an intersecting manner to achieve two-level blocking of the water flow, so as to slow down the drainage speed and drainage volume of the drainage outlet 11111, so that the water flowing to the guide platform 1115 can fall smoothly on the side wall of the door body or the door seal, so as to avoid the water discharged from the drainage outlet 11111 from accumulating on the surface of the guide platform 1115.

[0153] like Figure 7 、 Figure 10 As shown, second groove 1113 is provided with a partition 11132, which separates second groove 1113 to form cavities for the wiring terminals and the striking module 113. Partition 11132 is provided with a first notch 111321 for the wiring harness to pass through. Partition 11132 separates the striking module 113 from the wiring terminals, allowing them to be placed independently without interfering with each other. Furthermore, the connecting wiring harness of the striking module 113 passes through the first notch 111321 and connects to the wiring terminals.

[0154] The first cover 111 has a side wall structure extending away from the second cover 112 so as to be connected to the door panel 120 , the door liner 140 , the first side trim 150 , and the second side trim 160 respectively, for fixing and protecting the door.

[0155] like Figure 7 As shown, a side wall of the first cover 111 is provided with a plurality of first recesses 1119. The bottom ends of the first recesses 1119 and the side wall of the first cover 111 form first engaging notches 11191 for engaging the door panel 120 of the home appliance door. The door panel 120 is inserted into the first engaging notches 11191 and is held against the inner wall of the first cover 111 and the outer wall of the first recesses 1119, restricting the front-to-back movement of the door panel 120. The top end of the door panel 120 abuts against the inner wall of the first engaging notches 11191, restricting its upward movement. This positioning of the door panel 120 facilitates precise installation. The width of the first engaging notches 11191 is equal to or slightly greater than the thickness of the door panel 120, facilitating the insertion of the top end of the door panel 120 into the first engaging notches 11191.

[0156] like Figure 7 As shown, first engaging protrusions 1117 are provided on opposite side walls of the first cover 111, respectively engaging with the first side trim 150 and the second side trim 160. The corresponding side trims are provided with engaging grooves that engage with the first engaging protrusions 1117 to achieve engagement. The first engaging protrusions 1117 on both sides of the first cover 111 can have the same or different structures, as long as they achieve engagement.

[0157] like Figure 7 As shown, second latching protrusions 1124 are provided at both ends of the second cover 112, which are respectively engaged with the first side trim 150 and the second side trim 160, which form the side frames of the door body and door frame. The corresponding side trims are provided with latching grooves that latch with the second latching protrusions 1124 to achieve latching. The latching connection between the second latching protrusions 1124 and the side trims further improves the installation security of the second cover 112.

[0158] like Figure 7 As shown, the first cover 111 is provided with a plurality of second fixing portions 1118 for connecting with the door panel body 120. The second fixing portions 1118 are provided with through holes for fixing with the door panel body 120 and connected by screws.

[0159] like Figure 12 、 Figure 13 As shown, the lower end cover body 130 includes a bottom plate 131, and a plurality of second abutting portions 1311 and a plurality of first mounting portions 1312 are protruded from one side of the bottom plate 131 relative to the bracket body 210, and the first mounting portion 1312 is provided with a first mounting hole 13121; the plurality of second abutting portions 1311 respectively abut against one end of the bracket body 210 to realize the pressing and positioning pre-installation of the bracket body 210 relative to one end of the lower end cover body 130; the plurality of first mounting portions 1312 are fixedly connected to one end of the bracket body 210 through the first mounting hole 13121.

[0160] like Figure 12 As shown, the lower end cover body 130 is disposed at the bottom end of the foam door assembly 100. The lower end cover body 130 also includes four side walls, each of which is perpendicularly disposed on a side of the bottom plate 131 opposite the side of the bracket body 210. In one embodiment, since most home appliance doors have a rectangular structure, adjacent side walls are perpendicular to each other, which is suitable for commonly used home appliance doors.

[0161] like Figure 12 As shown, the height of the first mounting portion 1312 protruding from the bottom plate 131 is less than or equal to the height of the second abutting portion 1311 protruding from the bottom plate 131, so as to avoid interfering with the abutment between the second abutting portion 1311 and the fourth abutting portion 216, while reducing the depth of the first mounting hole 13121 on the first mounting portion 1312 to facilitate screw fixing.

[0162] like Figure 12As shown, a thin fixing plate 1313 is protruded from one side of the bottom plate 131, facing the bracket body 210. The fixing plate 1313 is provided with a second recessed portion 13131. A second engaging notch 13132 for engaging the door panel body 120 is provided between the second recessed portion 13131 and the fixing plate 1313. The second engaging notch 13132 secures the door panel body 120, forcing an outer wall of the door panel body 120 against the outer wall of the fixing plate 1313. When the door panel body 120 is assembled with the lower end cover body 130, one end of the door panel body 120 extends into the second engaging notch 13132 and is restrained there. This restricts the door panel body 120 from longitudinal movement toward the lower end cover body 130, thereby positioning the door panel body 120 for subsequent securing.

[0163] like Figure 14 、 Figure 15 As shown, the direction of the second abutting portion 1311 relative to the fixing plate 1313 can indicate the installation position of the transparent panel 230 , and the side of the second abutting portion 1311 away from the fixing plate 1313 is used to install the transparent panel 230 .

[0164] like Figure 12 As shown, in one embodiment, the height of the fixing plate 1313 protruding from the bottom plate 131 is equal to the height of the second abutting portion 1311 protruding from the bottom plate 131. When the fourth abutting portion 216 of the bracket body 210 is abutted and positioned with the second abutting portion of the lower end cover body 130, the door panel body 120 just extends into the second clamping notch 13132, and one end of the door panel body 120 relative to the lower end cover body 130 slightly protrudes from the outer end of the bracket body 210.

[0165] like Figure 12 、 Figure 16 、 Figure 17 As shown, the fixing plate 1313 is provided with a protruding second mounting portion 13133, one side of which abuts against an outer surface of the door panel body 120. The second mounting portion 13133 is provided with a second mounting hole 13133a for securely connecting to the door panel body 120. The door panel body 120 extends into the second engaging notch 13132 on the fixing plate 1313. The second engaging notch 13132 restricts the forward and backward movement of the door panel body 120. Align the second mounting hole 13133a with the corresponding mounting position on the door panel body 120 and secure with screws or rivets, making installation quick and easy.

[0166] like Figure 12As shown, third engaging protrusions 1314 are respectively provided at both ends of the bottom plate 131 to engage with corresponding engaging grooves (not shown) provided on the first side trim strip 150 and the second side trim strip 160 of the appliance door. In one embodiment, after the third engaging protrusions 1314 extend into the engaging grooves of the first side trim strip 150 or the second side trim strip 160 of the appliance door, the outer contour of the third engaging protrusions 1314 closely abuts the inner contour of the engaging grooves of the first side trim strip 150 or the second side trim strip 160. The bottom plate 131 restricts the longitudinal movement of the first side trim strip 150 or the second side trim strip 160 in the direction toward the bottom plate 131, while the third engaging protrusions 1314 restrict the lateral movement of the first side trim strip 150 or the second side trim strip 160, thereby accurately positioning and pre-assembling the side trim strips to the lower end cover body 130.

[0167] like Figure 12 、 Figure 13 As shown, one end of the bottom plate 131 near the second abutment portion 1311 extends to form a first platform 1315. The transparent panel 230 of the display screen assembly 200 is attached to the first side wall 1316 of the lower end cover body 130 and abuts against the first platform 1315. Furthermore, the width of the first platform 1315 is equal to the thickness of the transparent panel 230 of the home appliance door. This ensures that after the transparent panel 230 is attached to the first side wall 1316, the outer end of the first platform 1315 is flush with the outer surface of the transparent panel 230, resulting in a smooth and beautiful appearance for the home appliance door equipped with a display screen.

[0168] like Figure 12 、 Figure 13 As shown, the bottom plate 131 extends from both ends of the first side trim 150 and the second side trim 160 to form a second platform 1317. After the snap-in groove of the first side trim 150 or the second side trim 160 is snapped with the third snap-in protrusion 1314, the end face of the first side trim 150 or the second side trim 160 rests on the second platform 1317. The width of the second platform 1317 is equal to the wall thickness of the first side trim 150 or the second side trim 160, so that the outer end of the second platform 1317 is flush with the outer surface of the first side trim 150 or the second side trim 160 to cover the outer end of the outer wall of the corresponding first side trim 150 or the second side trim 160, so that the lower end cover body 130 and the first side trim 150 and the second side trim 160 form a closed space to prevent the foaming material from overflowing after foaming, and the resulting home appliance door body with the display screen assembly installed has a smooth and beautiful appearance.

[0169] A hinge hole (not shown) is provided on an outer wall of the bottom plate 131 away from the bracket body 210 for hingedly connecting the lower end cover body 130 to the appliance cabinet.

[0170] like Figure 25 、 26As shown, the outer surface of the lower end cover body 130 is provided with a groove 132, a closing cover (not shown in the figure), and a light source, and the light source is fixed on the light source fixing plate; the closing cover covers the outer side of the groove 132 to achieve sealing to prevent dust from accumulating in the groove 132; wherein,

[0171] At least two first snap-fit ​​structures 1321 are disposed within the recess 132. Each of the first snap-fit ​​structures 1321 includes a first fastening portion 13211. The first fastening portions 13211 of the at least two first snap-fit ​​structures 1321 face each other and respectively abut against two ends of an outer surface of the light source mounting plate, generating a relative snapping force to secure the two opposing sides of the light source mounting plate within the recess 132. The light source is secured to the light source mounting plate. In one embodiment, the light source is an LED lamp.

[0172] In one embodiment, at least two second snap-fit ​​structures 1322 are provided in the groove 132; the snap-fit ​​directions of the at least two second snap-fit ​​structures 1322 are opposite to each other, forming relative snap-fitting forces, and the inner wall of the closing cover is provided with a third snap-fitting structure (not shown in the figure) which is snap-fitted to the plurality of second snap-fitting structures 1322 respectively, so that the closing cover can be quickly snapped on or off the groove 132 to realize the installation and removal of the light source.

[0173] In one embodiment, a fifth through hole 1325 is provided in the groove 132. The wiring harness of the light source fixing plate passes through the fifth through hole 1325 and is electrically connected to the power supply module. The power supply module is electrically connected to the power supply module to connect or disconnect the light source to the power supply. The main control board 240 is electrically connected to the power supply module to control the connection or disconnection of the electrical connection between the power supply module and the power supply module, thereby controlling the turning on or off of the light source. After the wiring harness of the light source fixing plate is arranged, tape is applied to the back of the groove 132 to block the various holes on the back of the groove 132 to prevent subsequent foaming from clogging the various holes on the back of the groove 132.

[0174] like Figure 1 、 Figure 22 、 Figure 24 As shown, a first mounting structure 2124 for fixing the main control board 240 is provided on one side of the bracket body 210 facing the door panel body 120 , so as to quickly mount the main control board 240 electrically connected to the display screen 220 on the bracket body 210 .

[0175] like Figure 22 、 Figure 24As shown, a third groove 2125 is provided on the side of the bracket body 210 facing the door panel body 120 to reduce the weight of the bracket body 210. Furthermore, a first mounting structure 2124 for securing the main control board 240 is disposed within the third groove 2125 to prevent the installation of the main control board 240 from interfering with the engagement of the first limiting portion 1221 of the bracket body 210 with the door panel body 120, thereby reducing the thickness of the assembled appliance door body. Furthermore, to facilitate the electrical connection between the main control board 240 and the display screen, the third groove 2125 and the first mounting structure 2124 for securing the main control board 240 are both disposed on the back of the fixed bracket 212.

[0176] like Figure 1 As shown, the side of the bracket body 210 facing the door panel body 120 is provided with a second mounting structure 2126 for securing a human body sensing module 250. Furthermore, the human body sensing module 250 is embedded within the bracket body 210. The human body sensing module 250 senses the presence of a human body in front of the appliance door and sends a signal to the main control board 240, which controls the display screen to respond accordingly. The human body sensing module 250 includes an infrared sensing module or a microwave sensing module; the infrared sensing module senses changes in the infrared spectrum of the human body and sends different signals to the main control board 240, or the microwave sensing module senses changes in microwaves caused by the human body and sends different signals to the main control board 240. Furthermore, the second mounting structure 2126 is provided on the side of the fixed bracket 212 facing the door panel body 120 to facilitate interaction with the display screen 220.

[0177] The transparent panel 230 is against the inner wall of the door frame. Figure 14 、 Figure 15 As shown, the door frame extends along the periphery toward the transparent panel 230 to form a second extension 190. After the transparent panel 230 abuts the outer surface of the door frame, the second extension 190 adheres to the sidewall of the transparent panel 230 to seal the assembly gap between the door frame and the transparent panel 230, preventing dust accumulation and improving waterproofing. The second extension 190 includes the first platform 1315 and the second platform 1317 of the lower end cover body 130.

[0178] like Figure 21 As shown, a protrusion 141 is provided on the side of the door liner 140 close to the appliance box body; the protrusion 141 extends into the appliance box body, and the surrounding side of the protrusion 141 is tightly attached to the outer contour of the appliance box body to increase the sealing performance of the connection between the foam door body assembly 100 and the appliance box body.

[0179] The raised portion 141 is concave inwardly toward a direction away from the appliance housing to form a cavity 1411 . The cavity 1411 is provided with a third mounting structure 14111 of a shelf to provide storage space.

[0180] A door seal (not shown) is provided on the outer side of the raised portion 141 to seal the door liner 140 and the appliance housing to increase the sealing performance of the connection between the foam door assembly 100 and the appliance housing.

[0181] In one embodiment, the upper end cover body 110 and the lower end cover body 130 are both integrally injection-molded plastic parts, which have good structural mechanical properties, certain elasticity, are easy to assemble, and are not easily damaged.

[0182] like Figures 27 to 30 As shown, the household appliance door 10 further includes a logo display component, which includes a logo 231 and a light-emitting component 270; wherein,

[0183] The marker 231 is disposed on the transparent panel 230 and includes at least one light-transmitting area 232;

[0184] The light emitting member 270 is disposed on a side of the bracket body 210 close to the transparent panel 230 ; the light emitting member 270 is electrically connected to the main control board 240 ;

[0185] The bracket body 210 is provided with a hollow portion 2110;

[0186] After receiving the instruction, the main control board 240 configures the light-emitting component 270 to emit light. The light beam emitted by the light-emitting component 270 passes through the hollow portion 2110 and reaches the light-transmitting area 232 to illuminate the marker 231.

[0187] In one embodiment, the main control board 240 receives instructions to instruct the light-emitting member 270 to emit light, flash light, or change color to indicate to the user the remaining power of the appliance door 10 or abnormal usage of the display screen 220, thereby providing a warning. The specific configuration of the corresponding detection components and control components can be based on existing technologies and will not be further described here.

[0188] When only one light-transmitting area 232 is present, the light-transmitting area can be configured as any shape. Furthermore, because the light beam emitted by the light-emitting component is subject to reflection and other phenomena, multiple light-transmitting areas can be provided on the marker 231 to ensure light brightness or create different lighting effects. This allows as much light as possible to enter the light-transmitting area 232 on the transparent panel 230, or to create a richer lighting effect. The marker 231 and the light-transmitting area 232 can be of any shape. In some embodiments, the light-transmitting area 232 can overlap with a portion of the marker 231, or the light-transmitting area 232 and the marker 231 partially overlap, thereby forming a marker outline.

[0189] In some embodiments, the light-transmitting area 232 is teardrop-shaped, and the transparent panel 230 is a glass panel. To facilitate a clear and intuitive viewing of the light-transmitting area 232 by the user, the light-transmitting area 232 is disposed on the transparent panel, preferably anywhere between halfway along the appliance door 10 and the top or bottom of the appliance door 10. The light-transmitting area 232 is located between the top of the display screen 220 and the top of the appliance door 10. In other embodiments, the light-transmitting area 232 may be disposed to the side of the top of the appliance door 10 to avoid occupying space in the center of the top of the appliance door 10.

[0190] like Figure 1 As shown, in one embodiment, the light-transmitting area 232 is a teardrop-shaped hollow structure. It should be understood that the shape of the hollow structure can be designed according to specific needs. In order to ensure that the boundaries of the light-transmitting area 232 are clear, a multi-layer printing process can be used to set a teardrop-shaped hollow structure on each printed layer. The multi-layer hollow structure corresponds to the light-transmitting area 232 on the transparent panel 230. In addition, a transparent adhesive layer is provided on the side of the light-transmitting area 232 close to the bracket body 210. During the printing process, ink left on the transparent panel will cause the transparent panel to form irregular protrusions. The protrusions will cause gaps in the door assembly process or affect the installation of other components. Therefore, a transparent optical adhesive is applied to the side of the transparent panel 230 close to the bracket body 210 to form a transparent adhesive layer to make the surface of the light-transmitting area 232 smooth. In addition, the light-transmitting area 232 can be a light-transmitting area formed by a light-transmitting component. The light-transmitting area 232 is arranged along the outline of the marker 231. The light-transmitting area 232 is a teardrop-shaped hollow structure, the marker 231 is a V-shaped logo, and the teardrop-shaped light-transmitting area 232 is arranged along the V-shaped contour. Preferably, the light-transmitting area 232 overlaps with the marker 231 to form an overall contour consistent with the marker 231. In one embodiment, the light-transmitting area 232 is a teardrop-shaped hollow structure, the marker 231 is a V-shaped logo, and the teardrop-shaped hollow structure overlaps with the V-shaped marker. For example, the teardrop-shaped hollow structure of the light-transmitting area 232 is located exactly at the angle of the V-shaped logo, and the teardrop-shaped hollow structure is located within the V-shaped angle without exceeding the angle, so that the light-transmitting area 232 forms a part of the marker 231, forming a consistent overall contour. It should be understood that the marker and the light-transmitting area can have any other shape, pattern, or design, as long as they form a consistent overall contour. The marker 231 may be printed on the transparent panel 230 . In addition, the marker 231 may be a LOGO member installed on the transparent panel 230 , and the installation method may be bonding.

[0191] like Figure 1-4As shown, to conserve space between the transparent panel 230 and the bracket body 210, the light-emitting component 270 is directly integrated with or electrically connected to the main control board 240. The light-emitting component 270 is mounted on the side of the main control board 240 closest to the transparent panel 230. When the side of the transparent panel 230 closest to the bracket body 210 is coated with transparent optical adhesive, the light-emitting component 270 also includes a one-way transparent film disposed between the light-transmitting area 232 and the light-emitting component 270. The one-way transparent film adheres tightly to the transparent optical adhesive to prevent the light beam emitted by the light-emitting component 270 from being refracted by air bubbles. In some embodiments, the light-emitting component 270 is a single-colored LED. The main control board 240 varies the brightness of the light-emitting component 270 by changing the current flowing through the light-emitting component 270 to produce different display effects. It should be understood that in addition to the brightness of the light-emitting component 270, different display effects can also be achieved by varying the flashing frequency of the light-emitting component 270. In other embodiments, to enhance the difference in display effects, at least two different colored lamp beads are provided within the light-emitting member 270, and the corresponding lamp beads are controlled to emit light according to corresponding instructions from the main control board 240. It should be understood that in order to enhance the difference in display effects, in addition to distinguishing by color, the brightness of the lamp beads, the flashing frequency, etc. can also be combined to distinguish different display effects.

[0192] like Figure 1-4 As shown, in some embodiments, the main control board 240 further includes a plurality of ports, and the plurality of ports are used to control other components of the home appliance. Figure 3 As shown, the side of the main control board 240 away from the transparent panel 230 includes a first port 241, which is used to connect to the touch screen; a second port 242, which is used to connect to the WIFI module; a speaker port 243, which is used to connect to the speaker; and a fourth port 244, which is used to connect to the power supply. In addition, the side of the main control board 240 away from the transparent panel 230 also includes several other ports, which are connected to USB, Debug interface, camera, etc. Figure 4 As shown, the main control board 240 also includes several ports on one side close to the transparent panel 230, wherein the light-emitting component is directly integrated into or electrically connected to the main control board 240, avoiding the need for the light-emitting component to be fixed between the transparent panel 230 and the bracket body 210 through additional mounting parts in the traditional method, and the additional mounting parts will occupy the space between the transparent panel 230 and the bracket body 210.

[0193] In addition, the main control board 240 is integrated with or electrically connected to a microphone board 260 , and the microphone board 260 is connected to the microphone circuit.

[0194] The hollow portion 2110 covers the area where the light-emitting member 270 is located; the marker 231 and the light-emitting member 270 are located on either side of the hollow portion 2110. The hollow portion 2110 can be of any shape and can be covered with a light-transmitting member (such as a light-transmitting film) to facilitate the passage of light through the bracket body 210. The area where the hollow portion 2110 is located covers the area where the light-emitting member 270 is located, ensuring that the majority of the light beam emitted by the light-emitting member 270 can pass through the hollow portion 2110. In some embodiments, to guide light, the light-emitting member 270 is connected to a light guide column so that all light emitted by the light-emitting member 270 enters the hollow portion 2110.

[0195] After receiving the instruction, the main control board 240 configures the light-emitting component 270 to emit light. The light beam emitted by the light-emitting component 270 passes through the hollow portion 2110 and reaches the light-transmitting area 232 to illuminate the home appliance door body logo 231.

[0196] In some embodiments, as Figure 2-4 As shown, the main control board 240 includes a speaker port 243, and the speaker is connected to the speaker port. The speaker is set close to the marker 231, so that the sound emitted by the speaker and the light emitted by the light-transmitting area 232 are emitted from the same place of the bracket body 210, thereby enhancing the user's on-site experience.

[0197] In one embodiment, the identification display assembly further includes a light-emitting component control unit (not shown). One end of the light-emitting component control unit is connected to the light-emitting component 270, and the other end of the light-emitting component control unit is connected to the consumable module within the appliance housing. Specifically, the consumable module is located within the appliance housing and contains items such as deodorizers, odor removers, and freshness preservers. However, these items have a limited shelf life and, if used for a long time without replacement, can pollute the environment within the housing. Therefore, by providing the light-emitting component control unit, the usage of the items is linked to the light-emitting component. For example, the light-emitting component control unit may include at least a timer. Assuming a typical consumable module has a one-year lifespan, once the consumable module is installed, the timer begins recording the module's usage. For 0-6 months of usage, the light-emitting component control unit controls the light-emitting component to illuminate green. For 7-230 months of usage, the light-emitting component control unit controls the light-emitting component 270 to illuminate yellow. At the 210th month of usage, the light-emitting component control unit controls the light-emitting component 270 to illuminate red. The red light then indicates to the user that the consumable module should be replaced as soon as possible. It should be understood that the settings of the red light, green light, and yellow light can be set according to the service life of the consumable module. In addition, the light emitting component control unit may include an odor detector to prompt whether to replace the consumable module by detecting the gas concentration in the box.

[0198] The transparent panel 230 further includes a plurality of ventilation holes 233 , so that the heat generated by the display screen 220 can be dissipated through the ventilation holes 233 . In addition, the microphone board 260 on the main control board 240 can also receive sound through the ventilation holes 233 .
