Description

Technical Field

[0001] The utility model relates to the technical field of heating equipment, in particular to a wiring structure and a heating machine. Background Art

[0002] The heater is equipped with both high-power and low-power wires. High-power wires generally refer to those connected to the heater's high-power electrical components, such as the heating element. Low-power wires connect to components within the heater that are not high-power components, such as the mainboard and power board.

[0003] To reduce overall cost, heaters currently on the market often bundle the power and low-voltage wires together, creating safety risks for the entire product. Furthermore, bundling the power and low-voltage wires together makes wiring inconvenient and affects assembly efficiency. Utility Model Content

[0004] In view of this, the utility model provides a wiring structure and a heater to solve the problem that the strong wires and weak wires of the heater are bundled together, which poses a safety hazard and is inconvenient for wiring.

[0005] In a first aspect, the present invention provides a wiring structure for a heater, comprising:

[0006] A wiring housing is formed with a separate strong-current wiring cavity and a weak-current wiring cavity; the strong-current wiring cavity is used to route strong-current wires and has a strong-current wire inlet and a strong-current wire outlet; the weak-current wiring cavity is used to route weak-current wires and has a weak-current wire inlet and a weak-current wire outlet;

[0007] The wiring housing includes:

[0008] The U-shaped bracket has an open side, and the strong current line inlet and the weak current line inlet are arranged opposite to each other at two ends of the U-shaped bracket away from the open side;

[0009] The two outer covers are respectively buckled on the open sides of the U-shaped bracket, so that the high-voltage wiring cavity and the low-voltage wiring cavity are respectively formed between the U-shaped bracket and the two outer covers.

[0010] Beneficial effects: The wiring structure of the heater of the present invention forms relatively independent high-voltage wiring cavity and low-voltage wiring cavity in the wiring shell. Since the high-voltage wiring cavity and the low-voltage wiring cavity are arranged separately, the high-voltage wires and the low-voltage wires will not interfere with each other. Compared with the method of arranging the high-voltage wires and the low-voltage wires bundled together in the related art, the potential safety hazard caused by the mixed arrangement of high-voltage and low-voltage wires is eliminated, the safety and reliability of the heater are improved, and the user satisfaction is further improved. The wiring shell is a component that forms the separated high-voltage wiring cavity and the low-voltage wiring cavity. It adopts a U-shaped bracket. On the one hand, it is convenient to separate the high-voltage wiring cavity and the low-voltage wiring cavity, making wiring more convenient and quick; on the other hand, it enables the wiring structure to simultaneously serve as a supporting part to connect the base and the head of the heater. The structure is compact, and the U-shaped bracket will not interfere with the rotation of the head.

[0011] In an optional embodiment, a high-voltage fixing component for restraining the high-voltage wire is formed in the high-voltage wiring cavity; the high-voltage fixing component includes:

[0012] A first inlet trough is provided near the high-voltage power line inlet, and the inlet end of the high-voltage power line can be provided in the first inlet trough and fixed;

There is no need to set sheaths, heat shrink tubing or wire ties to restrain the weak current wires, thereby reducing wiring costs and significantly reducing the cost of the entire machine, which is conducive to further development and optimization of the product; the weak current wires at the wire inlet and outlet are prone to displacement and shaking, so a second wire inlet trough and a second wire outlet trough are respectively set near the weak current wire inlet and the weak current outlet to clamp the wire inlet and outlet ends of the weak current wires to prevent the wire harness from falling out or moving, avoid poor contact caused by unreliable fixation, and improve wiring reliability.

[0019] In an optional embodiment, a snap-fit ​​structure is provided at the slot openings of the first wire inlet slot, the first wire outlet slot, the second wire inlet slot, and the second wire outlet slot.

[0020] Beneficial effect: A snap-on structure is provided at the notch of the wire duct used for limiting and fixing the strong wires and weak wires, which facilitates the limiting, fixing and removal of the wire harness, makes the operation more convenient, and improves the wiring efficiency and the installation efficiency of the whole machine.

[0021] In an optional embodiment, the width D1 of the slots of the first inlet slot and the first outlet slot is equal to the diameter A of the power line. 强 , satisfying the relationship D1=(0.25~0.3)*A 强 The width D2 of the slot of the second inlet and outlet troughs is equal to the diameter A of the weak wires. 弱 , satisfying the relationship D2=(0.25~0.3)*A 弱 .

[0022] Beneficial Effects: The coefficient (0.25-0.3) is determined primarily to ensure the reliability of the cable tray's positional restraints and facilitate installation. If the coefficient is too large, installation may be facilitated, but wires may easily fall out of the cable tray. If the coefficient is too small, the positional restraints may be highly reliable, but installation of both high-voltage and low-voltage wires may be more laborious. Therefore, comprehensive design considerations are necessary. Setting the coefficient to 0.25-0.3 ensures both reliable positional restraints and convenient installation.

Those skilled in the art will understand the specific meanings of these terms in this utility model depending on the specific circumstances.

[0067] The following combination Figures 1 to 8 , describing the embodiments of the present utility model.

[0068] According to an embodiment of the present invention, on the one hand, Figure 1 and Figure 2 As shown, a wiring structure of a heater is provided, including:

[0069] The wiring housing 100 has a separate strong-current wiring cavity 101 and a weak-current wiring cavity 102 formed therein; the strong-current wiring cavity 101 is used to route strong-current wires and has a strong-current wire inlet 11 and a strong-current wire outlet 21; the weak-current wiring cavity 102 is used to route weak-current wires and has a weak-current wire inlet 12 and a weak-current wire outlet 22;

[0070] The wiring housing 100 includes:

[0071] The U-shaped bracket 1 has an open side, and a strong current line inlet 11 and a weak current line inlet 12 are arranged opposite to each other at two ends of the U-shaped bracket 1 away from the open side;

[0072] The outer covers 2 are respectively buckled on the open sides of the U-shaped bracket 1, so that a high-voltage wiring cavity 101 and a low-voltage wiring cavity 102 are respectively formed between the U-shaped bracket 1 and the two outer covers 2.

[0073] The wiring structure of the heater of the present invention forms a relatively independent strong-current wiring cavity 101 and weak-current wiring cavity 102 in the wiring housing 100. Since the strong-current wiring cavity 101 and the weak-current wiring cavity 102 are arranged separately, the strong and weak wires will not interfere with each other. Compared with the method of arranging the strong and weak wires together in the related art, the safety hazard caused by the mixed arrangement of strong and weak wires is eliminated, the safety and reliability of the heater are improved, and the user satisfaction is improved. The wiring housing 100 is a component that forms the separated strong-current wiring cavity 101 and weak-current wiring cavity 102. It adopts a U-shaped bracket 1. On the one hand, it is convenient to separate the strong-current wiring cavity 101 and the weak-current wiring cavity 102, making wiring more convenient and quick; on the other hand, it enables the wiring structure to simultaneously serve as a supporting part to connect the base 300 and the head 200 of the heater. The structure is compact, and the U-shaped bracket 1 will not interfere with the rotation of the head 200.

[0074] Depend on Figure 2 As can be seen from the cross-sectional view, the high-voltage wiring cavity 101 and the low-voltage wiring cavity 102 are respectively located on the left and right sides of the wiring housing 100. The two are arranged independently so that the high-voltage wires and the low-voltage wires do not interfere with each other, which meets safety regulations and improves the safety performance of the heater.

[0075] Furthermore, the high-voltage outlet 21 and the low-voltage outlet 22 are also arranged at intervals, which further improves safety and facilitates installation.

[0076] The high-voltage line inlet 11 and the low-voltage line inlet 12 are extended toward each other, and a protruding tubular structure is formed on the wiring shell 100. This arrangement makes it convenient to introduce the wires in the heater head 200 into the wiring shell 100, and the protruding tubular structure can also form a rotating axis, thereby realizing the purpose of rotating and pitching the heater head 200 along the rotating axis to blow air.

[0077] In some embodiments, the U-shaped bracket 1 and the outer cover 2 are connected by a snap-fit ​​structure, which includes a connecting slot 14 provided at the edge of the U-shaped bracket 1 and a connecting buckle 26 provided at the edge of the outer cover 2 for mating connection.

[0078] The U-shaped bracket 1 and the outer cover 2 are snap-fitted together by the connecting buckle 26 and the connecting slot 14 , which makes installation convenient and quick, and can improve assembly efficiency.

[0079] In some embodiments, one of the U-shaped bracket 1 and the outer cover 2 is provided with a positioning hole, and the other one is provided with a positioning column, and the positioning column cooperates with the positioning hole to form a positioning structure.

[0080] A positioning structure consisting of positioning posts and positioning holes is provided to perform initial positioning of the U-shaped bracket 1 and the outer cover 2 , thereby facilitating the two to be assembled together through the snap-fit ​​structure.

[0081] In this embodiment, the inner wall of the U-shaped bracket 1 extends toward the open side to form a positioning hole 13, and the corresponding position of the outer cover 2 is raised to form a positioning column 23. The shape of the positioning hole 13 matches the positioning column 23, and the positioning column 23 can be cylindrical or can be shaped like a Figure 5 The cross rib shape shown can save materials and reduce weight. Regardless of the shape, as long as the pre-assembly between the U-shaped bracket 1 and the outer cover 2 can be achieved, the subsequent assembly and connection can be facilitated after preliminary positioning. The number of positioning columns 23 is multiple to achieve reliable limiting. The setting position of the positioning column 23 is not limited. Preferably, it can be set at the end of the wiring housing 100, close to the position of the wire entry port, to facilitate positioning and matching. In some other embodiments, the positioning hole can also be set on the outer cover 2, and the positioning column is set on the U-shaped bracket 1.

[0082] In some embodiments, a stopper is formed at the mating edge of the U-shaped bracket 1 and the outer cover 2, and a counter-stopper 24 is formed at the edge of the outer cover 2. Specifically, the structure of the counter-stopper 24 is shown in FIG. Figure 5 , is a barbed hook structure formed near the positioning post 23 and extending to the edge of the outer cover 2.

[0083] The anti-stop 24 is provided to effectively prevent the U-shaped bracket 1 and the outer cover 2 from deformation and misalignment, causing the connection slot 14 on the U-shaped bracket 1 and the connection buckle 26 on the outer cover 2 to be separated by force, thereby avoiding cracking at the connection between the U-shaped bracket 1 and the outer cover 2.

[0084] The wiring methods in related technologies mostly use sheaths, heat shrink tubing or wire ties to fix them. All wires are bundled together first, and then the entire machine is routed, resulting in high overall machine costs and hindering product development.

[0085] In order to solve this problem, in some embodiments of the present invention, a high-voltage fixing component for restraining high-voltage wires is formed in the high-voltage wiring cavity 101 .

[0086] A high-voltage fixing component is provided in the high-voltage wiring cavity 101 for restraining and arranging the high-voltage wires. There is no need to provide sheaths, heat shrink tubing or wire ties to restrain the high-voltage wires, thereby reducing wiring costs and significantly reducing the cost of the entire machine, which is beneficial to product development and optimization.

[0087] In some embodiments, the strong current fixing assembly includes:

[0088] The strong current incoming line fixing structure is arranged near the strong current incoming line port 11;

[0089] The strong current outlet fixing structure is arranged near the strong current outlet port 21 .

[0090] The high-voltage wires at the wire inlet and wire outlet are prone to displacement and shaking, so a high-voltage wire inlet fixing structure and a high-voltage wire outlet fixing structure are respectively set near the high-voltage wire inlet 11 and the high-voltage wire outlet 21 to limit and fix the high-voltage wires, prevent poor contact caused by unreliable fixation of the wire harness, and improve wiring reliability.

[0091] Specifically, the high-voltage incoming line fixing structure includes a first incoming line groove 16 , and the incoming line end of the high-voltage line can be arranged in the first incoming line groove 16 and fixed.

[0092] The first wire inlet groove 16 is provided to clamp and fix the wire inlet end of the power line, thereby preventing the wire inlet end of the power line from falling out or moving, and making the fixation more secure.

[0093] In some embodiments, the high-voltage power line fixing structure includes a first power line slot 17 , and the power line end can be arranged in the first power line slot 17 and fixed.

[0094] The first outlet groove 17 is provided to clamp and fix the outlet end of the power line, thereby preventing the outlet end of the power line from falling out or moving, and making the fixation more secure.

[0095] In some embodiments, a high-voltage fixing component for restraining the high-voltage wires is formed in the high-voltage wiring cavity 101 , and a low-voltage fixing component for restraining the low-voltage wires is formed in the low-voltage wiring cavity 102 .

[0096] An electrical fixing component is set in the high-voltage wiring cavity 101, and a low-voltage fixing component is set in the low-voltage wiring cavity 102, which are used to restrain and arrange the high-voltage wires and low-voltage wires respectively. There is no need to set sheaths, heat shrink tubing or wire ties to restrain the low-voltage wires, thereby reducing wiring costs and significantly reducing the cost of the entire machine, which is conducive to further development and optimization of the product.

[0097] Furthermore, the weak current fixing assembly includes:

[0098] The weak current incoming line fixing structure is arranged near the weak current incoming line port 12;

[0099] The weak current outlet fixing structure is arranged near the weak current outlet port 22 .

[0100] The weak-current wires at the wire inlet and wire outlet are prone to displacement and shaking, so a weak-current wire inlet fixing structure and a weak-current wire outlet fixing structure are respectively set near the weak-current wire inlet 12 and the weak-current wire outlet 22 to limit and fix the weak-current wires, prevent poor contact caused by unreliable fixation of the wire harness, and improve wiring reliability.

[0101] Specifically, the weak-current incoming line fixing structure includes a second incoming line groove, and the incoming line end of the weak-current line can be arranged in the second incoming line groove and fixed.

[0102] A second wire entry groove is provided to clamp and fix the wire entry end of the weak wire to prevent the wire entry end from falling out or moving, and the fixation is more secure.

[0103] Similarly, the weak-current outgoing line fixing structure includes a second outgoing line groove, and the outgoing line end of the weak-current line can be arranged in the second outgoing line groove and fixed.

[0104] A second outlet groove is provided to clamp and fix the outlet end of the weak wire to prevent the outlet end of the weak wire from falling out or moving, and the fixation is more secure.

[0105] Specifically, if Figure 3As shown, the first wire inlet 16 is formed below the high-voltage wire inlet 11 and is located between the two positioning holes 13; the first wire outlet 17 is formed near the high-voltage wire outlet 21. Depending on the number of wire harnesses, if the wire harness diameter is large, multiple first wire outlet troughs 17 can be provided and dispersed. The second wire inlet and second wire outlet troughs are not shown in the figure. It should be noted that the structure of the second wire inlet trough is the same as that of the first wire inlet trough 16, and the structure of the second wire outlet trough is also the same as that of the first wire outlet trough 17. The second wire inlet and second wire outlet troughs are symmetrically arranged on the other side of the left-right symmetrical bisecting plane of the U-shaped bracket 1, respectively, with the first wire inlet trough 16 and the first wire outlet trough 17.

[0106] It should be noted that the first inlet trough 16, the first outlet trough 17, the second inlet trough and the second outlet trough are all provided with a buckle structure 18 at the slots. The structure of the buckle structure 18 is as follows: Figure 7 shown.

[0107] A snap-fit ​​structure 18 is provided at the notch of the wire duct for limiting and fixing the strong and weak wires, which facilitates the limiting, fixing and removal of the wire harness, makes the operation more convenient, and improves the wiring efficiency and the installation efficiency of the whole machine.

[0108] In an optional embodiment, the width D1 of the slots of the first inlet slot 16 and the first outlet slot 17 is equal to the diameter A of the power line. 强 , satisfying the relationship D1=(0.25~0.3)*A 强 The width D2 of the slot of the second inlet and outlet trough is equal to the diameter A of the weak wire. 弱 , satisfying the relationship D2=(0.25~0.3)*A 弱 .

[0109] The coefficient (0.25 to 0.3) is determined primarily to ensure the reliability of the cable trunking's positioning of the wires and facilitate installation. If the coefficient is too large, installation will be facilitated, but wires may easily fall out of the trunking. If the coefficient is too small, the positioning reliability is high, but installation of both high-voltage and low-voltage wires is more laborious. Therefore, comprehensive design considerations are necessary. Setting the coefficient to 0.25 to 0.3 ensures both reliable positioning and easy installation, achieving a balance between positioning reliability and ease of installation.

[0110] In an optional embodiment, as Figure 3 As shown, the edges of the high-voltage cable inlet 11 and the low-voltage cable inlet 12 as well as the connection points with the wiring harness are all equipped with rounded corners.

[0111] After setting the rounded corners 111 at the wire entry, the strong wires and weak wires enter the wiring structure through the strong wire entry 11 and the weak wire entry 12 respectively, avoiding the sharp parts at the edge of the wire entry or the connection with the wire harness, which may cause the wires to rub and the outer skin to be damaged, thereby increasing the service life of the strong wires and weak wires and improving safety performance.

[0112] According to an embodiment of the present invention, on the other hand, a heater is provided, comprising:

[0113] Base 300;

[0114] Nose 200;

[0115] The wiring structure, the head 200 is supported and installed on the base 300 through the wiring structure.

[0116] Since the heater includes the wiring structure of the present invention, it has the same technical effect as the wiring structure, which will not be described in detail here.

[0117] In some embodiments, as Figure 1 、 2 and Figure 8 As shown, the wiring housing 100 is provided with a shell buckle body 25, and the base 300 is provided with a seat buckle body 301, and the shell buckle body 25 and the seat buckle body 301 are buckled together.

[0118] The wiring housing 100 and the base 300 are provided with a housing buckle 25 and a seat buckle 301, respectively. The housing buckle 25 and the seat buckle 301 are connected in a coordinated manner, allowing for pre-fixation when installed with the base 300, facilitating subsequent assembly of other fasteners. In this embodiment, the fasteners are screws. After the housing buckle 25 is first fastened to the seat buckle 301 for positioning and pre-assembly, the two screws are then tightened to complete the assembly.

[0119] According to an embodiment of the present invention, a wiring structure of a heater is provided, which is arranged on a wiring housing 100. Figure 8 As shown, the wiring housing 100 is a U-shaped swing arm consisting of a U-shaped bracket 1 and two outer covers 2. The U-shaped bracket 1 is secured to the machine head 200 via an adapter 400. The U-shaped bracket 1 has a circular deep groove that fits into the machine head 200. The adapter 400 is placed in the circular deep groove and secured to the machine head 200 with two screws, thus completing the connection between the machine head 200 and the wiring structure.

[0120] The wiring housing 100 has a wire entry opening. A wire trough and a snap-fit ​​structure 18 are installed near the entry opening for pre-fixation. A snap-fit ​​structure 18 and a wire trough are also installed near the exit opening to further restrain the wires. The power and low-voltage wires of the entire system enter through the left and right entry openings, are restrained by the wire troughs, and then snapped into place by the snap-fit ​​structure 18 to secure them.

[0121] The U-shaped bracket 1 and the outer cover 2 in the U-shaped swing arm are installed by pre-fixing and guiding through the positioning columns 23 and the positioning holes 13, and then fixed through the connecting slots 14 on the top and left and right sides of the U-shaped bracket 1 and the connecting buckles 26 on the outer cover 2.

[0122] The strong and weak wires are led out from the outlets on the left and right outer covers 2 respectively and reach the inside of the base 300, completing the internal wiring of the whole machine and separating the strong and weak wires.

[0123] The wire entry of the U-shaped bracket 1 needs to have a fillet 111 with a radius of ≥ R3 to prevent the outer sheath from being damaged due to friction of the wires.

[0124] The U-shaped bracket 1 is a bilaterally symmetrical part. A wire outlet is provided on the outer cover 2 near the base 300, so that the wires in the strong current wiring cavity 101 and the weak current wiring cavity 102 can be extended into the base 300.

[0125] like Figure 7 As shown, the buckle structure 18 on the U-shaped bracket 1 is in the form of a door buckle. That is, by setting a reinforcing rib 15 inside the U-shaped bracket to connect with the inner wall to increase strength, the buckle structure 18 is then set on the reinforcing rib 15. A wire groove is set below the buckle structure 18 to constrain the wiring. The wire groove can be a square groove.

[0126] The relationship between the engagement of the snap structure 18, the width of the wire trough, and the internal wiring of the entire device is: D = (0.25-0.3)A. D is the engagement of the snap structure 18 or the width of the wire trough, A is the wire diameter, and (0.25-0.3) is the coefficient value. This relationship ensures that the snap structure 18 or the wire trough effectively secures the wires and also facilitates easy insertion of the wires.

[0127] Although the embodiments of the present invention have been described with reference to the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations shall fall within the scope defined by the appended claims.
