Description

Technical Field

[0001] The present application relates to the field of electrical appliance technology, and in particular to a wiring harness fixing device for a rotating screen, a flip screen assembly, a door body and a dishwasher. Background Art

[0002] In the field of dishwashers, when a flip screen structure is set on the door body, a wiring harness is needed to power the rotating screen, and the wiring harness rotates with the rotating screen when the rotating screen rotates. However, due to the thickness of the door body, the space left for the wiring harness in the door body is very narrow. At present, there are two main connection methods for the wiring harness connected to the rotating structure: one is that the wiring harness is led out along the inside of the rotating shaft or its adjacent area, for example, the wiring harness lead-out of the refrigerator door body, or the arrangement of the wiring harness at the rotating shaft of a laptop computer; the other is that the wiring harness is arranged in a direction perpendicular to the rotating shaft, such as the wiring of the car door body, or the wiring harness layout of the built-in dishwasher door body.

[0003] However, both of these connection methods have high technical requirements for the layout environment of the wiring harness and the performance of the wiring harness itself. The first method requires that there must be sufficient space inside the shaft or the wiring harness itself must be thin enough, and the wiring harness must also withstand the torsion force that may be applied. The second method requires a larger bending space, and the wiring harness must have excellent bending resistance. Therefore, the wiring harness layout methods in the prior art cannot meet the narrow space reserved for the wiring harness in the dishwasher door. Summary of the invention

[0013] In one of the embodiments, the height of the lowest point of the bending section during the rotation of the rotating member is lower than the heights of the fixed end and the moving end of the wire harness.

[0014] In one embodiment, the diameter of the wire harness is D, and in the direction of the rotation axis, the minimum distance between the axis of the moving end and the fixing member is A≥5D, and A≤150mm.

[0015] In one embodiment, the diameter of the wire harness is D, and in a direction perpendicular to the fixed surface, during the rotation of the rotating member relative to the fixed member, the maximum distance between the axis of the fixed end and the bending section is C, and D≤C≤3D.

[0016] In one embodiment, the range between the highest point and the lowest point of the bending section during the rotation of the rotating member is the rotation range of the rotating member, and in the direction perpendicular to the rotation axis and parallel to the fixed surface, the axis of the fixed end is located within the rotation range of the rotating member.

[0038] The present application provides a dishwasher, including a door body as described in the following embodiments, and an inner tank with a cleaning cavity, wherein the door body covers the inner tank and together with the inner tank, forms the cleaning cavity.

[0039] The present application also provides a door body, which can be applied to the above-mentioned dishwasher, or to any electrical appliance in the prior art, such as a washing machine, a dryer, etc. The door body includes a flip screen assembly 10 as described in the following embodiment, and the flip screen assembly 10 can be used to display cleaning hours and cleaning status.

[0040] See also Figure 1 and Figure 2 , Figure 1 and Figure 2The structure diagram of the flip screen assembly 10 in different states in an embodiment of the present application is shown. The flip screen assembly 10 provided in an embodiment of the present application can be connected to the top of the door body to display the working status and working time, or it can be directly installed on the main body of the appliance. Figure 1 and Figure 2 As shown, the flip screen assembly 10 includes a wire harness fixing device 100 for rotating a screen as described in any of the following embodiments, and also includes a screen assembly 200, which can be rotatably arranged around a rotation axis, and the screen assembly 200 has a Figure 1 The open state shown and Figure 2 Shown in closed state.

[0041] Combination Figure 3 and Figure 4 As shown, Figure 3 and Figure 4 The schematic diagrams of the structures of the wire harness fixing device 100 for a rotating screen in an embodiment of the present application are respectively shown in different states. An embodiment of the present application provides a wire harness fixing device 100 for a rotating screen, which includes a wire harness 130, a fixing member 110 and a rotating member 120. The rotating member 120 can rotate relative to the fixing member 110 around a rotation axis. The screen assembly 200 is connected to the rotating member 120 and rotates synchronously. Optionally, the rotating member 120 can be integrated with the screen assembly 200, and it is integrally formed with part of the structure in the screen assembly 200 to rotate synchronously. At this time, the rotating member 120 can be regarded as a part of the screen assembly 200. In other embodiments, the screen assembly 200 can also be fixedly connected to the rotating member 120. The screen assembly 200 can be rotatably connected to the fixing member 110 around a rotation axis, and the maximum angle and minimum angle of rotation of the rotating member 120 relative to the fixing member 110 correspond to the opening and closing of the screen assembly 200, respectively. In combination with the attached Figures 1 to 4 When the screen assembly 200 is in the Figure 1 In the open state shown in FIG. Figure 3 The maximum rotation angle relative to the fixing member 110 is shown. Figure 2 In the closed state shown, the rotating member 120 is as shown in FIG. Figure 4 The figure shows the minimum angle of rotation relative to the fixing member 110. For the convenience of description, the position of the rotating member 120 corresponding to the screen assembly 200 being in the open state is the first position, the position of the rotating member 120 corresponding to the screen assembly 200 being between the open state and the closed state is the second position, and the position of the rotating member 120 corresponding to the screen assembly 200 being in the closed state is the third position. Obviously, the second position is between the first position and the third position.

[0042] like Figure 3 and Figure 4 As shown, the fixing member 110 is provided with a fixing block 140, and the fixing block 140 is on one side in the axial direction parallel to the rotation axis, that is, the fixing block 140 is located on the left or right side of the rotating member 120. In the present embodiment, the fixing block 140 is located on the left side of the portion of the rotating member 120 for connecting the wiring harness 130. In other embodiments, the fixing block 140 may also be located on the right side of the rotating member 120.

[0043] like Figure 3 and Figure 4 As shown, the wire harness 130 includes a fixed end 131 and a moving end 132, wherein the fixed end 131 is connected to the fixed block 140, the moving end 132 is connected to the rotating member 120, and the axis of the moving end 132 is set at an angle with the rotating axis, so that when the rotating member 120 rotates, the wire harness 130 bends and twists between the fixed end 131 and the moving end 132, and at the same time, the bending strength and torsional strength of the wire harness 130 are utilized to enable the wire harness fixing device 100 of the rotating screen to be applied to the narrow space reserved when the flip screen assembly 10 is applied to the dishwasher door body. Small space, and low requirements for the single performance (flexural strength or torsional strength) of the wire harness 130. The flexural strength and torsional strength of the common wire harness 130 are both within a certain range. If the unidirectional performance of the wire harness 130 is required to be high, multiple twisting or bending will cause the wire harness 130 to break. The flexural strength and torsional strength of the wire harness 130 that are used at the same time are lower than those required for using the single performance of the wire harness 130, thereby avoiding twisting or breaking of the wire harness 130, making the wire harness 130 stable and durable during use.

[0044] like Figure 3 and Figure 4 As shown, the wire harness 130 also includes a bending section 133, and the fixed end 131 and the movable end 132 are respectively located at the two ends of the bending section 133. During the rotation of the rotating member 120 relative to the fixed member 110, the bending section 133 bends and twists to prevent the fixed end 131 and the movable end 132 from falling off, so that the wire harness 130 maintains a state in which both ends are restricted.

[0045] like Figure 3 or Figure 4 As shown, the angle between the axial direction of the fixed end 131 and the rotation axis is in the range of 0°-15°, so that the axial direction of the fixed end 131 and the rotation axis form a small angle, so that when the rotating member 120 rotates, the wire harness 130 is bent and slightly twisted at the fixed end 131. In this embodiment, the axial direction of the fixed end 131 is parallel to the rotation axis, so that when the rotating member 120 rotates, the wire harness 130 is bent at the fixed end 131 to reduce the torsional force.

[0046] In one embodiment, the fixing block 140 is provided with a threading hole 141 for the wire harness 130 to pass through, and the axis of the threading hole 141 is parallel to the rotation axis. In other embodiments, the fixing block 140 may also be provided with a buckle structure for clamping the wire harness 130.

[0047] In one embodiment, the included angle between the axis of the moving end 132 and the rotation axis is in the range of 75°-90°, so that when the rotating member 120 rotates, the harness 130 can swing along with the rotation of the rotating member 120. In one embodiment, the axis of the moving end 132 is perpendicular to the rotation axis. In other embodiments, the axis of the moving end 132 can also be inclined at other angles to the rotation axis, for example, the included angle between the axis of the moving end 132 and the rotation axis is 60°-75°.

[0048] like Figure 3 and Figure 4 As shown, in one embodiment, the fixing member 110 includes a fixing surface 111 on which the fixing block 140 is disposed, and the fixing surface 111 is parallel to the rotation axis, that is, the rotation plane of the rotating member 120 is perpendicular to the fixing surface 111 .

[0049] like Figure 5 As shown, in some embodiments, the height of the lowest point of the bending section 133 during the rotation of the rotating member 120 is lower than the height of the fixed end 131 and the moving end 132 of the wiring harness 130. Since the directions of the fixed end 131 and the moving end 132 are inconsistent, the two ends of the bending section 133 are connected in different directions, so that the bending section 133 bends. In this embodiment, the bending section 133 may be lower than the height of the moving end 132 to avoid the bending section 133 connected between the fixed end 131 and the moving end 132 being tensioned and subjected to a large bending force, thereby preventing the wiring harness 130 from being subjected to excessive force and being easily broken.

[0050] It can be understood that, in the direction of the rotation axis, the greater the distance between the axis of the moving end 132 and the fixing member 110, the smaller the bending force on the wire harness 130. Figure 5 As shown, Figure 51 shows the positions of the rotating member 120 and the harness 130 when the rotating member 120 is in the first position, the second position and the third position. In one embodiment, the diameter of the harness 130 is D, and the minimum distance A≥5D between the axis of the moving end 132 and the fixed member 110 in the direction of the rotation axis is reduced to reduce the bending degree of the harness 130 during the rotation of the rotating member 120, so as to avoid the distance between the axis of the moving end 132 and the fixed member 110 being too small. During the rotation of the rotating member 120, no matter where the rotating member 120 is between the first position and the third position, the position of the axis of the moving end 132 in the direction of the rotation axis remains unchanged, that is, the distance between the axis of the moving end 132 and the fixed member 110 remains unchanged. Therefore, when the axis of the moving end 132 rotates in the rotation plane with the rotating member 120, the distance between the rotation plane and the fixed member 110 is A. It is understandable that A is the minimum distance between the axis of the moving end 132 and the fixed member 110, which is not the minimum distance between the axis of the moving end 132 and the fixed member 110 during the rotation of the rotating member, but the minimum distance between the axis of the moving end 132 and the fixed member 110 when the rotating member 120 is stationary at any rotation angle during the rotation of the rotating member. In some embodiments, A is ≤ 150 mm to avoid the wire harness 130 being easily scratched by the swing due to the excessive distance between the rotating plane and the fixed member 110, and making it difficult to control the position of the wire harness 130.

[0051] Combination Figure 6 As shown, Figure 6 The positions of the rotating member 120 and the wiring harness 130 when the rotating member 120 is located in the first position, the second position and the third position are shown in FIG. In one embodiment, the diameter of the wiring harness 130 is D. In the direction perpendicular to the fixed surface 111, during the rotation of the rotating member 120 relative to the fixed member 110, the maximum distance between the axis of the fixed end 131 and the bending section 133 is C, and D≤C≤3D. Among them, C≤3D is used to limit the maximum height of the bending section 133 protruding from the fixed surface 111, so that the wiring harness fixing device 100 of the rotating screen can be applied to the confinement of a small space. D≤C is used to ensure that the wiring harness 130 always has a reasonable length of bending during the rotation process, so as to avoid the wiring harness 130 being stretched straight to produce a large local stress that makes the wiring harness 130 easy to be damaged. During the process of the rotating member 120 rotating from the first position to the third position, as shown in FIG. Figure 6 As shown, when the rotating member 120 is located at the first position, the bending section 133 protrudes the longest distance from the fixing surface 111 . At this time, the height difference between the bending section 133 and the axis of the fixing end 131 is the maximum distance C between the axis of the fixing end 131 and the bending section 133 .

[0052] It is understandable that when the axis of the fixed end 131 is aligned with the axis of the moving end 132, the torsional force on the wire harness 130 is minimal, and the greater the difference between the axis of the fixed end 131 and the axis of the moving end 132, the greater the torsional force on the wire harness 130. Figure 5 As shown, the range between the highest point and the lowest point of the bending section 133 during the rotation of the rotating member 120 is the rotation range of the rotating member 120, that is, the rotation range is: Figure 5 The polygonal area covered by the swing length B of the bending section 133 and the distance A between the axis of the moving end 132 and the fixed member 110 shown in the figure, in one embodiment, in the direction perpendicular to the rotation axis and parallel to the fixed surface 111, the axis of the fixed end 131 is located within the rotation range of the rotating member 120, so that there is at least a second position between the first position and the third position, and when the rotating member 120 is located at the second position, the axis of the fixed end 131 is flush with the axis of the moving end 132, and the torsional force on the wire harness 130 is minimal. When the rotating member 120 is located between the first position and the second position, the wire harness 130 is twisted, and when the rotating member 120 is located between the second position and the third position, the wire harness 130 is reversely twisted to avoid excessive torsional force on the wire harness 130 caused by excessive difference between the axis of the fixed end 131 and the axis of the moving end 132 during the rotation of the rotating member 120.

[0053] like Figure 5 As shown, in one embodiment, in a direction perpendicular to the rotation axis and parallel to the fixed surface 111, the axis of the fixed end 131 is located at the center of the rotation range of the rotating member 120, so that when the rotating member 120 rotates between the first position to the third position, the torsional force exerted on the wiring harness 130 is within a relatively small range.

[0054] like Figure 5 As shown, in one embodiment, during the rotation of the rotating member 120 relative to the fixed member 110 in a direction perpendicular to the rotation axis and parallel to the fixed surface 111, the swing length of the bending section 133 is B, wherein, in order to balance the torsional force and bending force exerted on the wiring harness 130, |BA| is less than 1 / 3A and |BA| is less than 1 / 3B.

[0055] In one embodiment, B=A to maximize the balance between the torsional force and the bending force on the harness 130 .

[0056] The wire harness fixing device 100 for a rotating screen provided in the above scheme is configured such that one end of the wire harness 130 is fixed parallel to the rotation axis, and the other end is arranged at an angle to the rotation axis and rotates synchronously with the rotating member 120, so that when the rotating member 120 rotates, the wire harness 130 is bent and twisted between the fixed end 131 and the moving end 132. At the same time, the bending strength and torsional strength of the wire harness 130 are utilized, so that the wire harness fixing device 100 for a rotating screen can be applied to the narrow space reserved when the flip screen assembly 10 is applied to the door body of a dishwasher. , and the requirements for the single performance (flexural strength or torsional strength) of the wire harness 130 are relatively low. The flexural strength and torsional strength of the common wire harness 130 are both within a certain range. If the unidirectional performance requirements of the wire harness 130 are relatively high, multiple twisting or bending will cause the wire harness 130 to break. By utilizing the flexural strength and torsional strength of the wire harness 130 at the same time, the flexural strength and torsional strength required for utilizing the single performance of the wire harness 130 are lower, thereby avoiding the twisting or breaking of the wire harness 130, making the wire harness 130 stable and durable during use.

[0057] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0058] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
