[0040] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0041] The following disclosure provides many different embodiments or examples for implementing different structures of the present invention.

[0042] One embodiment of the present invention provides a wire fixing bracket for an electrical appliance, comprising a door hinge 200 and a fixing bracket 300, wherein the door hinge 200 is fixed to the electrical appliance; the fixing bracket 300 is detachably connected to the door hinge 200, and the fixing bracket 300 is used to fix the wires.

[0043] In this embodiment, the door hinge 200 can be installed on the electrical appliance, that is, on the housing 100 of the washing machine, by riveting, welding, etc., to connect the housing 100 and the door body. When the washing machine expands its functions, it is necessary to add wiring, and the wiring will pass through the inside of the housing 100. Since the internal structure of the washing machine housing 100 has been finalized, it is necessary to detachably connect the fixed bracket 300 to the door hinge 200. In order to realize the detachable connection of the fixed bracket 300 to the door hinge 200, this embodiment provides a variety of implementation methods. For example, the fixed bracket 300 is attached to the door hinge 200 with tape. Or the door hinge 200 is made of iron material, and the fixed bracket 300 is clamped together by a magnet and an iron door hinge 200. The above-mentioned implementation methods of detachably connecting the fixed bracket 300 to the door hinge 200 do not require changing the structure of the door hinge 200 or the housing 100, which is convenient for fixing the wiring harness when the washing machine product expands its functions later. It is understandable that the wires can be fixed to the fixing bracket 300 by means of tape or by embedding the wires into the grooves on the fixing bracket 300. The way of fixing the wires to the fixing bracket 300 is easy for technicians in this field to think of and will not be elaborated in this article.

[0044] Reference Figure 2 and Figure 3 As shown, another embodiment of the present invention provides a wire fixing bracket. Further, the door hinge 200 includes a fixed page 210, a rotating page 220 and a rotating shaft 230. The fixed page 210 is fixed on the appliance, and the fixing bracket 300 is detachably connected to the fixed page 210.

[0045] In this embodiment, the fixed page 210 of the door hinge 200 can be installed on the housing 100 by riveting, welding, etc. Considering that the rotating page 220 of the door hinge 200 is connected to the door body of the washing machine and needs to be rotated frequently, and frequent movements may cause damage to the wires, the fixed bracket 300 is set on the fixed page 210 to reduce the failure rate of the wires due to the rotation of the door hinge 200.

[0046] Reference Figure 3 As shown, another embodiment of the present invention provides a wire fixing bracket, and the fixing bracket 300 is provided with a wire harness fixing hook 330 or a wire harness fixing hole.

[0047] In this embodiment, in order to facilitate the connection of the wires to the fixing bracket 300, a wire harness fixing hook 330 or a wire harness fixing hole is provided on the fixing bracket 300. The wire harness fixing hook 330 is in a groove shape. When in use, the wire is embedded in the wire harness fixing hook 330. Generally, more than two wire harness fixing hooks 330 are provided on the fixing bracket 300, and there is no need to use adhesive tape or binding tape to fix the wires on the fixing bracket 300, thereby improving the convenience of wire installation. In order to further enhance the connection stability of the wires on the fixing bracket 300, more than two wire harness fixing holes are provided on the fixing bracket 300. When installing, one end of the wire is passed through more than two wire harness fixing holes in sequence to fix the wires on the fixing bracket 300.

[0048] Reference Figure 2 As shown, another embodiment of the present invention provides a fixing bracket installation structure for an electrical appliance, comprising a bolt 400, a door hinge 200 and a fixing bracket 300; the door hinge 200 is fixedly connected to the electrical appliance via a bolt 400; the fixing bracket 300 is detachably connected to the bolt 400, and the fixing bracket 300 is used to fix the wires.

[0049] In this embodiment, the door hinge 200 is mounted on the washing machine housing 100 by using a bolt 400, so that the bolt 400 is added to the door hinge 200. In combination with the bolt 400, a structure for more conveniently mounting the fixing bracket 300 on the door hinge 200 can be provided. It can be imagined that one of the implementation methods is to set a through hole on the fixing bracket 300, one end of the bolt 400 passes through the through hole, and the bolt 400 is pressed on the door hinge 200. In this implementation method, the structure of the bolt 400 does not need to be changed. Another implementation method is to set a through groove at the bottom of the fixing bracket 300, and an elastic rubber ring is set on the inner wall of the through groove. The through groove is set on the top of the bolt 400, so that the top of the bolt 400 is embedded in the through groove, and the top of the bolt 400 is clamped by the through groove and the elastic rubber ring, so as to realize the detachable connection between the fixing bracket 300 and the bolt 400. In this implementation method, the structure of the bolt 400 does not need to be changed, and it is easy to install. It is understandable that the implementation method of detachably mounting the fixing bracket 300 on the bolt 400 is not limited to the above two methods, and other implementation methods that can be easily thought of by those skilled in the art also belong to the protection scope of the present invention.

[0050] Reference Figure 6 and Figure 7 As shown, an embodiment of the present invention provides a fixed bracket installation structure, wherein the fixed bracket 300 is provided with a mounting hole 310 and a limiting mechanism; the frame on the fixed bracket 300 for surrounding the mounting hole 310 is sleeved on the bolt 400, and the limiting mechanism is connected to the bolt 400 for limiting the fixed bracket 300.

[0051] In this embodiment, the diameter of the mounting hole 310 is larger than the diameter of the top end of the bolt 400, and the diameter of the top end of the bolt 400 is larger than the diameter of the threaded column 430 of the bolt 400. The top end of the bolt 400 can extend into the mounting hole 310 without contacting the inner wall of the mounting hole 310. Since the inner wall of the mounting hole 310 and the bolt 400 may not contact each other, a limiting mechanism needs to be provided on the fixing bracket 300 in order to limit the fixing bracket 300 on the bolt 400. For example, a retaining spring is provided on the frame surrounding the mounting hole 310. After the top end of the bolt 400 extends from one end of the mounting hole 310 and extends from the other end of the mounting hole 310, the top end of the bolt 400 is clamped by the retaining spring. The retaining spring realizes the limiting mechanism, and there is no need to change the structure of the bolt 400. The installation is convenient and quick.

[0052] This embodiment also provides another implementation of the limiting mechanism. In this implementation, the frame surrounding the mounting hole 310 is made of elastic materials such as rubber or silicone. The diameter of the mounting hole 310 is smaller than the diameter of the bolt 400. Since the frame surrounding the mounting hole 310 is elastic, the top of the bolt 400 can be embedded in the mounting hole 310, and the bolt 400 is clamped by the frame surrounding the mounting hole 310. In this implementation, the limiting mechanism is the frame surrounding the mounting hole 310, and the structure is simpler and easy to install.

[0053] Reference Figure 4 , Figure 5 and Figure 8 As shown, a specific embodiment of the present invention provides a fixing bracket installation structure, wherein the bolt 400 includes a cover body 410, a boss 420 arranged on the lower surface of the cover body 410, and a threaded column 430 arranged on the lower surface of the boss 420; the limiting mechanism includes a cantilever 320, and the cantilever 320 includes a fixed end 322 connected to the fixing bracket 300 and a free end 323 capable of swinging around the fixed end 322; wherein the frame is sleeved on the outer periphery of the boss 420, and the free end 323 abuts against the lower surface of the cover body 410.

[0054] In this embodiment, the structure of the bolt 400 is improved compared to the existing structure. The structure of the traditional bolt only includes a threaded column 430 and a cover body 410 whose diameter is larger than that of the threaded column 430. Therefore, the traditional bolt structure only has a first-level step surface located on the lower surface of the cover body 410. Therefore, when using a traditional bolt to install the fixing bracket 300 on the door hinge 200, the bottom of the fixing bracket 300 is generally abutted against the door hinge 200, and the lower surface of the cover body 410 is abutted against the upper surface of the fixing bracket 300, and the cover body 410 presses the fixing bracket 300, and then the fixing bracket 300 presses the door hinge 200 against the box body 100.

[0055] In this embodiment, the structure of the bolt 400 is improved by adding a boss 420 structure between the cover body 410 and the threaded column 430, thereby forming two-level stepped surfaces on the lower surface of the cover body 410 and the lower surface of the boss 420. The lower surface of the boss 420 is used to press the door hinge 200, and the lower surface of the cover body 410 is used to press the fixing bracket 300. When the fixing bracket 300 needs to be removed, the installation and fixation of the door hinge 200 will not be affected. In this embodiment, the cantilever 320 is elastic, and the cantilever 320 is made of elastic plastic or metal sheet. The mounting hole 310 is a strip hole, the width of which is greater than the diameter of the cover body 410. The strip hole is sleeved on the bolt 400, and the frame surrounding the strip hole is attached to the boss 420, and can slide along the straight line formed by the connection of the two bolts 400. When the fixing bracket 300 slides to a certain position, the free end 323 of the cantilever 320 abuts against the lower surface of the cover body 410, providing the fixing bracket 300 with an axial downward elastic force along the threaded column 430, so as to limit the fixing bracket 300 relative to the bolt 400.

[0056] Reference Figure 6 and Figure 7 As shown, another embodiment of the present invention provides a fixed bracket installation structure, the installation hole 310 includes a loading portion 311 and a limiting portion 312, the limiting mechanism is arranged on the limiting portion 312, the number of the cantilever 320 is two, and a limiting block 321 is arranged on the upper surface of each cantilever 320; the two cantilevers 320 surround a limiting groove, and the opening of the limiting groove is formed between the free ends 323 of the two cantilevers 320, and the opening of the limiting groove faces the loading portion 311, the minimum value of the distance between the two limiting blocks 321 is a, and the maximum value of the straight-line distance between any two points on the side surface of the cover body 410 is b, and the relationship between a and b is: a <b。

[0057] In this embodiment, the mounting hole 310 is a strip-shaped hole with one end larger than the other end, that is, the diameter of the insertion portion 311 is larger than the diameter of the limiting portion 312, and the diameter of the insertion portion 311 is larger than the diameter of the cover body 410; the diameter of the limiting portion 312 is smaller than the diameter of the cover body 410. After the cover body 410 is inserted into the insertion portion 311, the outer periphery of the frame-fitting boss 420 surrounding the mounting hole 310 is slid, so that the bolt 400 is inserted into the limiting portion 312 through the notch formed by the free ends 323 of the two cantilevers 320, and the bolt 400 is also in the limit formed by the two cantilevers 320. The outline of the frame surrounding the limiting portion 312 is a semicircular shape matching the outer periphery of the boss 420, so the bolt 400 can no longer move toward the limiting portion 312. Since the limiting blocks 321 are provided on the two cantilevers 320, the bolt 400 is also blocked by the one-way limiting structure formed by the two limiting blocks 321 and cannot move from the limiting portion 312 to the loading portion 311, so it is limited in the limiting portion 312. At the same time, the cantilever 320 abuts against the lower surface of the cover body 410, and the fixing bracket 300 is firmly connected to the bolt 400 by the elastic force provided by the cantilever 320 in the axial direction of the threaded column 430. Therefore, in this embodiment, the mounting hole 310 structure with one end larger than the other end is provided to facilitate the installation of the fixing bracket 300, and the cantilever 320 provided cooperates with the limiting portion 312 to achieve the firm fixation of the fixing bracket 300 on the bolt 400.

[0058] Reference Figure 6 As shown, in this embodiment, the aperture of the strip hole described refers to the transverse aperture, wherein the longitudinal direction of the strip hole refers to the direction of relative movement of the boss 420 of the bolt 400 in contact with the frame surrounding the strip hole, and the transverse direction of the strip hole is perpendicular to the longitudinal direction.

[0059] Reference Figure 7 As shown, another embodiment of the present invention provides a fixed bracket installation structure, and an inclined surface 3210 is provided on the end of the limit block 321 away from the fixed end 322.

[0060] In this embodiment, since the free ends 323 on the two cantilevers 320 form the openings of the limiting grooves, the process of installing the fixing bracket 300 on the bolt 400 is the process of moving the bolt 400 from the insertion portion 311 to the limiting portion 312. In order to reduce the resistance caused by the limiting block 321 during the movement of the bolt 400 from the insertion portion 311 to the limiting portion 312, an inclined surface 3210 is provided on the end of the limiting block 321 away from the fixed end 322. The inclined surface 3210 has a guiding function and is used to guide the cover body 410 of the bolt 400 to pass through the limiting block 321. After the cover body 410 passes through the limit block 321, the distance between the two limit blocks 321 is also smaller than the diameter of the cover body 410, and the two cantilevers 320 abut against the lower surface of the cover body 410. The two limit blocks 321 are located on the side of the cover body 410 facing the limit groove opening and abut against the side of the cover body 410 facing the limit groove opening, so as to limit the movement of the cover body 410 toward the groove opening.

[0061] Reference Figure 1 As shown, an embodiment of the present invention provides a washing machine, including a wire fixing bracket or a fixing bracket installation structure of any of the above embodiments. The specific implementation method can refer to the above embodiments, and will not be repeated here to avoid redundancy.

[0062] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
