Description

Technical Field

[0001] The present invention belongs to the technical field of clothing processing, and in particular relates to a clothing processing device. Background Art

[0002] Washing machines are common appliances in daily life, and most are currently semi-automatic or fully automatic. These machines require an electrical system to control the washing process, such as determining the current wash cycle and operating parameters such as the timing and motor speed of each step within the cycle, to ensure optimal performance. This electrical system primarily consists of a circuit board and associated wiring harnesses, which connect to the corresponding electrical components within the washing machine to ensure their proper operation.

[0003] Electrical systems require a relatively dry environment to function properly. However, washing machines are often used in high-humidity environments such as restrooms. This can cause moisture to enter the electrical system, such as the distribution box, condense on the walls, and flow to the bottom of the box. This can cause short circuits or even damage to the circuit boards located there, compromising the reliability of the washing machine. Furthermore, water can splash onto the circuit boards during the wash cycle, causing them to short circuit or even damage.

[0004] Accordingly, this field requires a new technical solution to solve the above problems. Summary of the Invention

[0005] In order to solve the above-mentioned problems in the prior art, that is, to solve the problems that the circuit boards of existing clothing processing equipment are easily short-circuited and damaged due to the ingress of liquid, the present invention provides a clothing processing equipment, wherein the clothing processing equipment includes a distribution box, the distribution box includes a box body, a box cover, a bracket and a circuit board assembly, the box body and the box cover are buckled together to form a cavity, the bracket is located in the cavity and fixed to the box body, the circuit board assembly includes a first circuit board, the bracket is formed with a reserved space on one side close to the bottom of the box body, the first circuit board is arranged in the reserved space, wherein there is a gap between the reserved space and the bottom of the box body so that the first circuit board can be suspended on the box body.

[0006] In the preferred technical solution of the above-mentioned clothing processing device, the bracket is provided with a plurality of hooks on one side close to the bottom of the box body, the plurality of hooks and the bracket form the reserved space, the first circuit board is placed in the reserved space, and in the assembled state, there is a gap between the hooks and the bottom of the box body.

[0007] In the preferred technical solution of the above-mentioned clothing processing device, the outer edge of the bracket extends with a flange in the direction close to the box body, and the hook is arranged on the flange, wherein the flange abuts against the inner side of the bottom of the box body, and there is a gap between the hook and the inner side of the bottom of the box body.

[0008] In a preferred technical solution of the above-mentioned clothes processing device, the circuit board assembly includes a second circuit board, and the second circuit board is fixed to a side of the bracket away from the bottom of the box body.

[0009] In the preferred technical solution of the above-mentioned laundry processing device, a limiting structure is provided on the inner wall of the box body, and the limiting structure abuts against the upper surface of the bracket so that the bracket is fixed in the box body through the limiting structure and the flange.

[0010] In the preferred technical solution of the above-mentioned clothing processing device, the outer wall of the box body is provided with a plurality of buckles, and the box cover is provided with a plurality of buckle holes, so that the box cover and the box body are snap-fitted together by matching the buckles with the corresponding buckle holes, wherein each of the buckles includes a buckle unit or a plurality of buckle units arranged in parallel.

[0011] In a preferred technical solution of the above-mentioned clothes processing device, the multiple buckles located on one side of the box body extend to have protruding ends at the end close to the box body.

[0012] In the preferred technical solution of the above-mentioned clothing processing equipment, an anti-reverse insertion pin hole is provided at the bottom of the box body, an upgrade terminal is provided on the circuit board assembly, and the upgrade wiring harness terminal is connected to the upgrade terminal through the anti-reverse insertion pin hole.

[0013] In the preferred technical solution of the above-mentioned clothing processing equipment, a wiring harness hole is provided on the box body so that the wiring harness can pass through the cavity, and a plurality of claws are provided on the outer wall of the box body. The plurality of claws and the outer wall of the box body form a wiring groove, so that the wiring harness passing through the cavity can be distributed on the outer wall of the box body along the wiring groove.

[0014] In a preferred technical solution of the above-mentioned clothing processing device, a mounting position is provided on the clothing processing device, a positioning column is provided at the bottom of the box body, and the box body is installed to the clothing processing device by matching the positioning column with the mounting position.

[0015] Those skilled in the art will appreciate that, in the technical solution of the present invention, the distribution box includes a box body, a box cover, a bracket, and a circuit board assembly. The box body and the box cover are connected by snapping together to facilitate installation and removal. A bracket is disposed within the cavity formed by the box body and the box cover, and is fixed within the box body to secure the circuit board assembly within the distribution box. The circuit board assembly includes a first circuit board, and the bracket has a reserved space formed on one side near the bottom of the box body, with a gap between the reserved space and the bottom of the box body.

[0016] Thus, by placing the first circuit board within the reserved space, the first circuit board can be suspended within the box body. This arrangement reduces the possibility of liquid coming into contact with the first circuit board, causing a short circuit or even damage to the first circuit board, such as condensed water on the distribution box flowing onto the bottom of the distribution box. This is particularly true when the distribution box body is relatively small, such as when the distribution box itself is small or when the installation space reserved for the distribution box in a washing machine is limited. This arrangement allows the first circuit board to be suspended within the box body without the need for a bracket, thereby ensuring the reliability of the distribution box.

[0017] In a preferred technical solution of the present invention, a first circuit board and a second circuit board are mounted on the lower and upper surfaces of the bracket, respectively. The outer edge of the bracket extends toward the bottom of the box body with a flange, and a plurality of hooks are provided on the flange, with the lower end slightly higher than the flange. Thus, in the assembled state, the flange rests against the inner side of the bottom of the box body, the hooks are suspended, and the first circuit board is placed in the reserved space formed by the plurality of hooks and the lower surface of the bracket. Obviously, the reserved space is located above the bottom of the box body, and the first circuit board in the reserved space can be suspended above the bottom of the box body. Therefore, with such a setting, the first circuit board assembly can be reliably suspended in the box body without the need to suspend the bracket to the bottom of the box body in order to achieve suspension, and therefore, no special space needs to be reserved.

[0018] Compared to a single circuit board, placing the first and second circuit boards separately on the lower and upper surfaces of the bracket significantly reduces the cross-sectional area of ​​the box. Therefore, the present invention enables the installed circuit boards to perform as many electrical functions as possible, even with a relatively small cross-sectional area. Furthermore, because the second circuit board is located on the upper surface of the bracket, suspension only needs to be performed for the first circuit board. In short, the collaboration between the flange and the hook improves the adaptability of the box to spaces with narrow heights. The segmented circuit board arrangement also enhances the adaptability of the box to spaces with narrow horizontal dimensions. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] Preferred embodiments of the present invention are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely intended to illustrate the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. For example, although this embodiment uses a washing machine as an example, other types of clothing processing appliances, such as dryers, integrated washing and drying machines, or multi-machine washing machines, may also be applied.

[0035] It should be noted that in the description of the present invention, terms such as "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer" indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings. These are merely for ease of description and are not intended to indicate or imply that the device or element described must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0036] Reference Figure 1 、 Figure 2 and Figure 4 , Figure 1 1 is a schematic structural diagram of a power distribution box of a washing machine according to an embodiment of the present invention. Figure 2 1 is a schematic cross-sectional view of a power distribution box of a washing machine according to an embodiment of the present invention. Figure 4 Schematic diagram of the structure of the power distribution box of a washing machine according to an embodiment of the present invention, wherein the bracket is installed in the box body. Figure 1 、 Figure 2 and Figure 4 Shown and referenced Figure 1In the illustrated position, the washing machine of the present invention includes a power distribution box. The washing machine is provided with a mounting position, and a positioning post 4 is provided at the bottom of the power distribution box. The positioning post 4 is used to mate with the mounting position to secure the box to the washing machine. The power distribution box is connected to the various electrical components of the washing machine, thereby controlling the washing machine to operate according to a predetermined program or switching the power supply of the various electrical components to meet the electrical needs of the washing machine. The power distribution box includes a box body 1 and a box cover 2. The box body and the box cover are fixed together by interlocking to form a cavity. A bracket 3 is fixedly disposed within the cavity to secure a circuit board assembly to the bracket, thereby enabling the circuit board assembly to be placed within the power distribution box. The circuit board assembly includes a first circuit board and a second circuit board, respectively mounted below and above the bracket. A reserved space for mounting the first circuit board is formed below the bracket, with a gap between the reserved space and the bottom of the box body. For example, the reserved space is a drawer cavity with a side opening or an open cavity with a bottom opening. By installing the first circuit board within the reserved space, the first circuit board can be mounted on the bracket. Since there is a gap between the reserved space and the bottom of the box body, when the first circuit board is installed in the reserved space, there is naturally a gap between it and the bottom of the box body. In this way, the first circuit board can be suspended in the box body, reducing the possibility of the first circuit board being short-circuited or damaged due to contact between liquid and the first circuit board.

[0037] For example, the first circuit board can be placed in the reserved space by means of a clip-on arrangement. Of course, the clip-on arrangement is merely an example description. Without departing from the principles of the present invention, those skilled in the art can adjust the above arrangement as needed to suit specific applications, such as by gluing.

[0038] In order to meet the electrical requirements of a washing machine, sufficient circuit board assemblies need to be provided. However, the sizes of distribution boxes that match different models and types of washing machines are also different. If the horizontal dimension of the distribution box, that is, the cross-sectional area, is large enough, then one circuit board can be provided to meet the electrical requirements of the washing machine. If the horizontal and vertical dimensions of the distribution box are small, that is, the cross-sectional area and height are small, then the electrical requirements can be met by providing multiple circuit boards. Therefore, the arrangement of the circuit boards in the distribution box can be set according to actual needs. The first circuit board of the present invention is suspended below the bracket and the second circuit board is mounted above the bracket. In this way, the distribution box equipped with the circuit board assembly only needs smaller horizontal and vertical dimensions.

[0039] In order to avoid short circuit or even damage caused by contact between the circuit board assembly and the liquid at the bottom of the box, it is necessary to use a bracket to ensure a certain distance between the circuit board assembly and the bottom of the box, that is, to suspend the circuit board assembly in the box. Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 9 to illustrate a possible embodiment of arranging the circuit board assembly in a suspended manner in the box.

[0040] Reference Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8 , Figure 5 This is a schematic cross-sectional view of a bracket of a power distribution box of a washing machine installed in a box body according to an embodiment of the present invention. Figure 6 Figure 5 The enlarged schematic diagram of part B in the middle, Figure 7 This is a structural diagram of the lower side of the bracket of the power distribution box of a washing machine according to an embodiment of the present invention. Figure 8 yes Figure 7 The enlarged schematic diagram of the local C in the figure. Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8 As shown and in accordance with Figure 4 In the orientation shown in FIG, the bracket 3 is positioned within the box body 1. Multiple flanges 31 extend downward from the outer edge of the bracket. Several hooks 311 are positioned on the inner sides of some of the flanges, with the hooks configured to be wider at the top and narrower at the bottom. Multiple ribs 312 extend downward from the inner sides of the flanges, with the ends of the ribs protruding above the upper surfaces of the hooks. This creates a reserved space between the ribs 312 and the hooks 311, allowing the first circuit board to be positioned within the reserved space, thereby securing the first circuit board to the bracket. Furthermore, the lower surfaces of the hooks 311 are elevated above the ends of the flanges 31, which abut against the inner side of the bottom 12 of the box body. This creates a distance between the reserved space and the ends of the flanges, i.e., the inner side of the bottom, thereby suspending the first circuit board within the box body. In other words, only a small height is required below the bracket to suspend the first circuit board. It is understood that the hook can also form a reserved space with the lower surface of the bracket, without the need for additional ribs to form a reserved space with the hook, which is suitable for situations with very small vertical dimensions. It is also understood that it is also possible to simply have multiple hooks below the bracket, and the multiple hooks and the lower surface of the bracket form a reserved space capable of accommodating the first circuit board. Those skilled in the art can adjust the arrangement of the reserved space as needed to suit specific applications.

[0041] Continue to refer to Figure 4 、 Figure 5 and Figure 6 ,like Figure 4 、 Figure 5 and Figure 6 As shown and in accordance with Figure 4 In the orientation shown in FIG, the circuit board assembly further includes a second circuit board, which is fixedly mounted above bracket 3, for example, by a retaining post 32 disposed in the middle of the upper portion of the bracket and a second latch 33 disposed on the rear side. The upper portion of bracket 3 is positioned away from the bottom 12 of the box body, thereby ensuring that the second circuit board is positioned away from the bottom of the box body, thereby suspending the second circuit board within the box body. It will be appreciated that the second circuit board may also be secured above the bracket by other means, such as by a plurality of retaining latches.

[0042] Reference Figure 9A and 9B , Figure 9A This is a schematic structural diagram of a washing machine support and a limiting structure abutting against each other according to an embodiment of the present invention. Figure 9B yes Figure 9A The enlarged schematic diagram of the local D in FIG. Figure 9A and 9B As shown and in accordance with Figure 9A In the orientation shown, a limiting structure is provided on the inner wall of the box body 1. For example, two third clips 13 are provided on the longer left and right side walls of the inner wall of the box body. The third clips 13 are composed of two clip units connected at the bottom. The upper surfaces of the left and right sides of the bracket respectively abut against the lower surfaces of the third clips 13. Under the action of the third clips 13, the bracket is fixed in the box body to prevent the bracket from moving upward. It is understandable that the number of clips can be determined according to actual needs to ensure that the bracket can be fixed in the box body. Without departing from the principles of the present invention, those skilled in the art can adjust the setting method of the limiting structure as needed to adapt to specific applications.

[0043] In order to facilitate the installation of the circuit board components and brackets, the box body and the box cover of the distribution box are set separately, and the two are fixed in a buckle-fitting manner. In this way, when the circuit board components and brackets need to be disassembled, the box cover is opened, and after the installation is completed, the box cover is buckled on the box body, which is simple and convenient to operate. Figure 1 、 Figure 2 and Figure 3 To illustrate possible implementation methods of the box body and the box cover fastening.

[0044] Reference Figure 1 、 Figure 2 and Figure 3 , Figure 3 yes Figure 1 The enlarged schematic diagram of the part A in FIG. Figure 1 、 Figure 2 and Figure 3 As shown and in accordance with Figure 1As shown in the figure, the distribution box is a roughly rectangular parallelepiped structure. Two first latches 11 are provided on the outer sides of the longer side walls of the box body, and one first latch 11 is provided on the outer sides of the shorter side walls. The box cover is provided with multiple latch holes 21 on the corresponding side walls, matching the first latches. The first latches 11 correspond to the latch holes 21 one-to-one, allowing the box cover 2 to be fastened to the box body 1. The first latches 11 are arranged in parallel with two latch units, each of which is narrow at the top and wide at the bottom. The lower edges of the latch holes 21 abut against the lower edges of the two latch units, thereby achieving a mating engagement between the box cover 2 and the box body 1. It is understood that the number of latches and latch holes can be determined based on the specific dimensions of the distribution box, for example, two latches can be provided on each edge of the box body, and two latch holes can be provided on each edge of the box cover. It is also understood that the latches can also include one latch unit or multiple latch units, such as three. Those skilled in the art can adjust the number of latches and latch holes, as well as the specific form of the latches, as needed to suit specific applications.

[0045] Continue to refer to Figure 1 、 Figure 2 and Figure 3 The buckle on the longer side of the box body extends downward with an extended end 111, and the lateral dimension of the extended end 111 is smaller than that of the upper buckle. In this way, during the installation process, the two matching card holes 21 on the box cover 2 first connect with the inner side of the extended end 111, and then the box cover rotates around the connection point toward the inside of the box body where the bracket is provided, so that the other three card holes 21 set on the edge are matched and buckled with the buckle 11.

[0046] The function of the circuit board assembly is to control the washing program of the washing machine and the power switching of various components of the washing machine. In this way, it is necessary to set a wiring harness between the first circuit board, the second circuit board and the various components of the washing machine so that the automation of the washing machine can be realized through the circuit board assembly.

[0047] Reference Figure 7 and Figure 10 , Figure 10 FIG. 1 is a schematic diagram of the structure of a power distribution box of a washing machine according to an embodiment of the present invention. Figure 7 and Figure 10 As shown and in accordance with Figure 10 As shown in the figure, a plurality of mounting slots 34 are provided on the bracket, and the wiring harness terminals are provided in the mounting slots 34. The wiring harness passes through the wiring harness hole 14 provided on the box body of the distribution box so as to be connected to the various electrical components of the washing machine.

[0048] Furthermore, to secure and organize the multiple wiring harnesses exiting the distribution box on the outer wall, the bracket is equipped with multiple harness securing structures. As shown in Figure 10, the outer wall of the box body is also provided with multiple staggered claws 15. Adjacent claws are arranged in an inverted fashion on the outer wall of the box body. These claws 15 and the outer wall of the box body 1 form a wiring trough. This arrangement allows the wiring harnesses exiting the cavity to be distributed along the wiring trough on the outer wall of the box body. Furthermore, limiting holes 16 are distributed along the outer wall of the box body, allowing the wiring harnesses to be secured using cable ties or other means when they pass through the limiting holes.

[0049] Reference Figure 11 , Figure 11 It is a structural diagram of the bottom of the power distribution box of a washing machine according to an embodiment of the present invention. In order to facilitate operation when the program of the circuit board assembly needs to be updated, a pin hole is provided on the distribution box, and an upgrade terminal is provided on the circuit board assembly. The pin hole is opposite to the upgrade terminal. When a program upgrade is required, the upgrade wiring harness terminal only needs to be inserted into the pin hole and connected to the upgrade terminal to achieve the program upgrade. Furthermore, in order to prevent damage to the circuit board due to incorrect wire sequence when the wiring harness terminal is connected, the pin holes are staggered to avoid wrong insertion, that is, by providing anti-reverse insertion pin holes 17 on the distribution box, the smooth progress of the upgrade is ensured. In addition, the diameter of the pin hole should not be too large or too small, such as φ2mm. At this time, the tension of water can just block the pin hole but will not fall into the distribution box. If it is too large, liquid may enter the distribution box. If it is too small, it may not match the pin of the wiring harness terminal.

[0050] In summary, in the preferred technical solution of the present invention, the circuit board assembly includes a first circuit board and a second circuit board, and the two are respectively arranged on the lower surface and upper surface of the bracket. In this way, when the horizontal dimension of the distribution box is small, the electrical requirements of the washing machine can be met. Among them, the outer edge of the bracket extends downward with multiple flanges, and multiple hooks are provided on the flanges. The flanges are against the bottom of the box body and the lower ends of the hooks are slightly higher than the flanges. In this way, a reserved space that can accommodate the first circuit board is formed between the lower surface of the bracket and the hooks, and there is a gap between the reserved space and the inner side of the bottom of the box body. In other words, only a small height is required below the bracket to achieve the purpose of suspending the first circuit board in the box body, reducing the possibility of short circuit or even damage caused by contact between liquid and the circuit board assembly. It can be seen that the present invention can greatly improve the adaptability of the assembly box to narrow spaces while meeting electrical reliability.

[0051] Thus far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art may make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will fall within the scope of protection of the present invention.
