[0002] Household appliances are necessities in people's lives. The door body of a household appliance is one of the important components of the household appliance, which plays a role in isolating or insulating the interior of the household appliance from the exterior. The function of the household appliance door body is not only to isolate or insulate, but also to bring some other spiritual-level enjoyments to users. For example, a display screen is added to the household appliance door body to provide users with a diverse intelligent experience. Therefore, inevitably, there will be some structures such as circuit boards and circuit wiring harnesses inside the household appliance door body. In addition, when users use household appliances, due to the water droplets that may condense on the outer wall of the end cover of the household appliance door body, or because users are used to placing green plants on the top of the household appliance, water may penetrate to the outer wall of the end cover of the household appliance door body, and then the water penetrates into the household appliance door body along the connection between the peripheral side of the end cover and the decorative strip, the door panel body and the door liner, which may cause potential safety hazards to the circuit. Therefore, a corresponding drainage structure needs to be set to drain the water existing on the outer wall of the end cover without penetrating into the household appliance door body. Some of the existing drainage structures of household appliance door bodies are directly set on the outer side of the top of the household appliance door body, which affects the aesthetics and is easy to accumulate dust; some drain along the side wall of the household appliance door body to the bottom of the household appliance door body through a drainage groove, with a complex structure and high requirements for assembly accuracy.

[0003] In addition, various wire harnesses are inevitably required for electrical connection, and the terminal is an essential electrical connection fitting. For the terminal, the existing household appliance door bodies usually set the terminal inside the household appliance door body, which requires corresponding structures to be set in the household appliance door body to accommodate the terminal, and is not convenient for maintenance and replacement. Some household appliance door bodies set the terminal in the hinge shaft hole of the household appliance door body. Such a design is not applicable to structures with a large number of wiring harnesses, and the appearance is not beautiful. A shielding structure needs to be added. Such a shielding structure needs to satisfy both shielding and not affecting the pivotal connection between the household appliance door body and the household appliance cabinet, so a more complex structure is required, increasing unnecessary costs and installation procedures.

[0004] Generally, in order to increase the adsorption force between the household appliance door body and the household appliance cabinet, a magnet is set in the door liner. When the door needs to be opened, a certain force needs to be applied by the user. When the user holds an object in his hand, it is relatively difficult to open the household appliance door. In order to provide users with diverse functional experiences, the use of knocking to open or close the household appliance door, or the use of knocking to achieve a human-computer interaction experience on the household appliance door body has also begun to be taken seriously by enterprises. In the existing household appliance door bodies, the knocking sensor is usually set inside the household appliance door body, which is not convenient for maintenance or replacement.

It should be noted that, on the premise of no conflict, the following-described embodiments or technical features can be arbitrarily combined with each other to form new embodiments.

[0045] Embodiment 1

[0046] As Figure 1 , Figure 2 , Figure 6As shown in the figure, the present invention provides an end cover for a household appliance door body, which includes an end cover body 110 provided at the top of the household appliance door body. The end cover body 110 includes a first cover body 111 and a second cover body 112. Among them,

[0047] The first cover body 111 is provided with a drainage groove 1111. In one embodiment, in order to facilitate drainage, a drainage port 11111 is provided on one side of the drainage groove 1111. The bottom surface of the drainage groove 1111 is a slope, which gradually becomes lower along the direction towards the drainage port 11111. The drainage port 11111 is located on the side where the low end of the slope is located, forming a drainage structure to guide water droplets to the drainage port 11111 for discharge;

[0048] The upper surface of the first cover body 111 is provided with a first groove 1113 for accommodating the wiring terminal and the wiring terminal. A through groove 11131 for the wire harness to pass through is provided in the first groove 1113. The wire harness for electrical connection passes through the through groove 11131 outside the first groove 1113 and is connected to the wiring terminal;

[0049] The second cover body 112 is fixed on the top of the first cover body 111 to form a covering structure for the drainage groove 1111 and the first groove 1113.

[0050] The first cover body 111 is provided with a first through hole 11151 for pivotally connecting to the household appliance box body. At the same time, the wire harness of the display screen assembly of the refrigerator door body passes through the through groove 11131 and is connected to the wiring terminal. The wire harness in the refrigerator box body passes through the first through hole 11151 and the through groove 11131 in sequence and is connected to the wiring terminal.

[0051] A first fixing portion 11133 is provided in the first groove 1113. The knocking module 113 is accommodated in the first groove 1113 and fixed to the first fixing portion 11133.

[0052] The second cover body 112 seals the periphery of the drainage groove 1111, and a notch is left corresponding to the drainage port 11111 for the drainage groove 1111 to drain water. Due to the principle that water flows to lower places, the drainage groove 1111 timely drains the water droplets that may accumulate on the upper surface of the end cover body 110.

[0053] As Figure 3 shown, 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. The bottom of the threaded holes 1116 is closed. The plurality of threaded holes 1116 and the plurality of second through holes 1122 respectively correspond to each other for the screws to pass through for screw connection.

[0054] As Figure 1 、 Figure 2As shown, the first cover 111 is provided with a second groove 1112; a drain groove 1111 and a first groove 1113 are respectively arranged in the second groove 1112, and a drain port 11111 is arranged on the side wall of the second groove 1112; the second cover 112 covers the second groove 1112; wherein,

[0055] An outer wall of the first groove 1113 corresponding to the inner region of the second groove 1112 extends upward to form 11134, and a diversion cavity 1114 is formed between 11134 and the inner wall of the second groove 1112; the diversion cavity 1114 is connected to the drain groove 1111;

[0056] At least one screw connection part between the first cover 111 and the second cover 112 corresponds to the diversion cavity 1114, so that water droplets on the outer wall of the first cover 111 enter the diversion cavity 1114 from the screw connection part and then flow into the drain groove 1111.

[0057] As Figure 1 、 Figure 2 shown, the first threaded hole 11161 located in the diversion cavity 1114 is a common threaded hole, and the second threaded hole 11162 located in the first groove 1113 for placing a terminal and / or a knocking module 113 can be a threaded hole made of a slightly expandable material or waterproof treatment is carried out in the threaded hole, 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 water droplets on the outer wall of the end cover body 110 will not fall into the first groove 1113, but will only specifically fall into the diversion cavity 1114 for diversion drainage to achieve effective and safe drainage.

[0058] As Figure 1 、 Figure 2 shown, the first cover 111 is provided with a diversion platform 1115 corresponding to the drain port 11111, and the height of the diversion platform 1115 is lower than the bottom of the drain port 11111, so that the water accumulated in the drain groove 1111 is discharged along the drain port 11111 to the diversion platform 1115, and then falls along the side wall of the door body or the door seal near the diversion platform 1115. A first through hole 11151 is arranged on the diversion platform 1115, and the surface where the diversion platform 1115 is located is lower than the surface where the drain groove 1111 is located, so as to avoid the hinge connection affecting the connection between the second cover 112 and the first cover 111. The drain groove 1111 and the diversion platform 1115 are close to the pivot connection part of the refrigerator door body and the refrigerator box body, and fall along the side wall of the door body or the door seal near the diversion platform 1115, and the drainage route is hidden and safe without affecting the user experience.

[0059] One side wall of the first groove 1113 coincides with one side wall of the second groove 1112 to increase the space of the first groove 1113 for accommodating the terminal and / or the knocking module 113. The first groove 1113 is rectangular, and three outer walls form a diversion cavity 1114 with the inner area of the second groove 1112, and one side wall coincides with one side of the second groove 1112.

[0060] As Figure 1 、 Figure 2 shown, an installation platform 11121 for placing the second cover 112 is provided on the inner wall of the second groove 1112 to make the outer surface of the second cover 112 flush with the outer surface of the first cover 111. That is, one surface of the second cover 112 fits on the installation platform 11121, the side wall of the second cover 112 located in the second groove 1112 fits with the inner wall of the second groove 1112, and the outer surface of the second cover 112 is flush with the outer surface of the first cover 111 to make the upper surface of the end cover body 110 flat and beautiful.

[0061] As Figure 1 、 Figure 2 、 Figure 3 shown, a diversion protrusion 1121 is provided on the inner surface of the second cover 112, and a diversion groove 11211 is provided on the diversion protrusion 1121; the diversion protrusion 1121 corresponds to the diversion cavity 1114 to guide water droplets to flow into the drainage groove 1111 along the diversion cavity 1114.

[0062] In one embodiment, as Figure 3 shown, one end of the diversion protrusion 1121 is connected to the outer wall of the second through hole 1122 that is far from the drainage groove 1111 and corresponds to the diversion cavity 1114 to guide the water on the outer surface of the second cover 112 to leave first from the connection between the second cover 112 and the second through hole 1122 that is far from the drainage groove and corresponds to the diversion cavity 1114, and then flow to the drainage groove 1111 along the diversion cavity 1114 to dredge the water flow so as to prevent too much water from accumulating on the surface of the first cover 111. As Figure 1 、 Figure 2 shown, the drainage groove 1111 is close to the pivoting part of the refrigerator door body and the refrigerator cabinet body, and the second through hole 1122 that is far 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 first groove 1113.

[0063] As Figure 4As shown, the diversion protrusion 1121 extends into the diversion cavity 1114 without contacting the bottom surface of the diversion cavity 1114, leaving a space for water droplets to flow along the diversion cavity 1114. Since the amount of water droplets accumulating on the end cap body 110 is not large, and the screw connection between the first cover body 111 and the second cover body 112 is relatively tight, the water droplets or small water flows will enter the first threaded hole 11161 in the diversion cavity 1114 along the screw connection between the first cover body 111 and the second cover body 112. The water droplets overflow from the first threaded hole 11161 and, under the pushing action of their own gravity, enter the drainage groove 1111 along the diversion groove 11211 provided on the diversion protrusion 1121 for drainage. Due to the diversion effect of the diversion groove 11211, the water droplets are easily diverted along the diversion groove 11211, and the water droplets on the end cap body 110 easily flow downward from the second through hole 1122 connected to the diversion protrusion 1121 and then enter the corresponding area of the diversion cavity 1114 corresponding to the second through hole 1122. Further, for the sake of clear explanation, as Figure 1 , Figure 2 , Figure 4 shown, the first diversion cavity 11141 is far from the drainage groove 1111, the third diversion cavity 11143 is close to the drainage groove 1111, and the second diversion cavity 11142 is located between the first diversion cavity 11141 and the third diversion cavity 11143. The water droplets are easy to flow in from the second through hole 1122 connected to the diversion protrusion 1121 and flow through the first diversion cavity 11141, the second diversion cavity 11142, and the third diversion cavity 11143 in sequence along the diversion groove 11211, and finally flow into the drainage groove 1111.

[0064] As Figure 3 shown, the diversion protrusion 1121 is provided with a bent extension part 11212 to prevent the water droplets in the diversion cavity 1114 from entering the threaded hole 1116 located in the diversion cavity 1114 and close to the drainage groove 1111. That is, as Figure 1 , Figure 2 shown, the two first threaded holes 11161 in the third diversion cavity 11143 close to the drainage groove 1111 are partially blocked by the extension part 11212 between them and the drainage groove 1111. If there is water accumulation on the surface of the third diversion cavity 11143, the water will flow to the lower place, that is, flow into the drainage groove 1111. Even if there is too much water accumulation on the surface of the third diversion cavity 11143, due to the partial blockage of the extension part 11212 and the different sizes of the spaces on both sides of the extension part 11212, the accumulated water on the surface of the third diversion cavity 11143 is not easy to flow to the two first threaded holes 11161 but directly flows into the drainage groove 1111; if the water on the outer surface of the end cap body 110 flows into the two first threaded holes 11161 in the third diversion cavity 11143 and overflows, since there is still a gap between the extension part 11212 and the surface of the third diversion cavity 11143, the water flows through this gap and reaches the drainage groove 1111 to achieve drainage.

[0065] As Figure 5 shown, near the drain opening 11111 in the drain trough 1111, first baffles 11112 and second baffles 11113 with intersecting and corresponding positions are provided to achieve two-stage blocking of the water flow, so as to slow down the drainage speed and drainage volume of the drain opening 11111, and enable the water flowing to the diversion platform 1115 to smoothly fall on the side wall or door seal of the door body, so as to prevent the water discharged from the drain opening 11111 from accumulating on the surface of the diversion platform 1115.

[0066] As Figure 1 , Figure 2 , Figure 3 shown, one end of the second cover 112 is provided with a bent portion 1123 to seal the contact portion between one end of the second cover 112 and the upper surface of the first cover 111, so as to improve the waterproof performance of the end cover body 110. Since the second cover 112 is provided with the bent portion 1123, the bent portion is closely attached to an outer wall of the first cover 111, and the side wall height of the second groove 1112 near the bent portion 1123 of the first cover 111 does not exceed the height of the installation table 11121 and can support one end of the second cover 112.

[0067] As Figure 2 shown, the bent portion 1123 is provided with a plurality of abutting portions 1125 for abutting against the bracket body for fixing the display screen of the display screen assembly. The abutting portions 1125 are positioning protrusions, and the bracket body is provided with positioning grooves for abutting against the abutting portions 1125, which is convenient for precise assembly. The abutting portions 1125 are positioning protrusions and gradually narrow along their extending directions, so as to facilitate the abutting portions 1125 to extend into the corresponding positioning grooves; the outer contour of the abutting portions 1125 extending into the corresponding positioning grooves of the bracket body fits with the inner contour of the positioning grooves to enhance the stability of the snap connection. In one embodiment, the abutting portions 1125 are triangular positioning protrusions, and the positioning grooves of the bracket body are triangular. The triangular abutting portions 1125 abut against the positioning grooves on the display screen bracket, increasing the abutting force between one end of the second cover 112 and the display screen bracket, so as to press one end of the display screen bracket and prevent the display screen bracket from shaking inside the refrigerator door body.

[0068] 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 passes through the fixing hole and is screwed into the threaded hole to fix the knocking module 113. The knocking module 113 is electrically connected to the main control board arranged inside the refrigerator door body, and can form an identification of whether the user performs a knocking action on the refrigerator door body and instruct the refrigerator to make a response according to the user's knocking operation. For example, opening the refrigerator door and turning on the refrigerator lighting through the user's knocking action.

[0069] The knock module 113 includes a knock sensor, which can receive the vibration generated by the user knocking on the refrigerator door to sense the vibration signal of knocking on the refrigerator door. The knock module 113 also includes a control unit electrically connected to the knock sensor. The control unit can be directly set on the main control board in the refrigerator door or set 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, an instruction is issued to make the refrigerator door respond; if it is not a preset knock vibration, the refrigerator door does not respond.

[0070] The first cover body 111 has side wall structures extending on all sides in a direction away from the first groove 1113, which are connected to the side trims on both sides to surround the door panel body, door liner, foaming layer and other sheet metal foam door body components and display screen components to play a role in fixing and protecting.

[0071] like Figure 6 As shown, a side wall of the first cover body 111 is provided with a plurality of recessed portions 1119, and the bottom end of the recessed portion 1119 and the side wall of the first cover body 111 form a snap-in notch 11191 for snapping the door panel body of the refrigerator door body; the door panel body is snapped into the snap-in notch 11191, and is supported by the inner wall of the first cover body 111 and the outer wall of the recessed portion 1119, limiting the movement of the door panel body in the front-to-back direction. The top end of the door panel body is pressed against the inner wall of the snap-in notch 11191, limiting the upward movement of the door panel body. Because the door panel body is limited, accurate installation is facilitated. The width of the snap-in notch 11191 is equal to or slightly larger than the thickness of the door panel body, so that the top end of the door panel body can be snapped into the snap-in notch 11191.
