Description

Technical Field

[0001] The utility model belongs to the technical field of household appliances, and in particular relates to a notch structure for leading out a wire harness, a keypad back plate, and a gas water heater. Background Art

[0002] A gas water heater, also known as a gas water boiler, is a gas appliance that uses gas as fuel and transfers heat to cold water flowing through a heat exchanger through combustion heating to achieve the purpose of preparing hot water.

[0003] After sufficient market research, gas water heaters with large-screen appearance display structures are more popular with consumers. For the large-screen control structure, the back panel of the keypad often involves multiple signal transmission harnesses, which need to be exported through the slots. If the structure and position of the slots are not reasonably designed, they are likely to interfere with other fixed and installed structures on the board. In addition, the opened slots are likely to significantly reduce the strength of the board itself. Utility Model Content

[0004] In order to solve the above technical problems, the present application further improves the existing panel notch structure, in order to minimize the impact on the panel strength and make the notch layout more reasonable. One of the purposes of the present utility model is to provide a notch structure for leading out the wiring harness, the second purpose is to provide a corresponding keypad back panel, and the third purpose is to provide a corresponding gas water heater.

[0005] The specific technical solutions are described below:

[0006] A notch structure for exporting a wire harness, comprising a notch;

[0007] The notch is arranged at the edge of the board surface, and at the same time, the notch is opened at the extension track of the reinforcing rib on the board surface.

[0008] If the slot structure is opened at the flat plate position of the board, the strength of the flat plate will be greatly reduced (the flat plate is made of plastic, and its own strength is not high), and additional consideration must be given to how to avoid interference with the numerous components on the board.

[0009] In the above technical solution, in addition to being able to conveniently export the wiring harness on the board, the notch is also located at the extension trajectory of the reinforcing rib rather than at other positions on the board, thereby reducing the impact on the strength of the board. Furthermore, since other components on the board need to be separated from the reinforcing rib, the notch follows the extension trajectory of the reinforcing rib and can also avoid other components arranged on the board, making the layout more reasonable.

[0010] Preferably, one end of the slot is arranged adjacent to the end of the reinforcement rib, so that the reinforcement rib can be extended as much as possible when the length of the slot is determined, and since the end of the reinforcement rib is arranged at the end of the slot, the reinforcement rib can also form a partial guide and limit function for the wire harness lead-out slot.

[0011] Further preferably, an arc-shaped wire harness guide portion is provided at one end of the slot adjacent to the reinforcement rib. In addition to the guiding function of the reinforcement rib itself, the wire harness guide portion can also further guide the wire harness through the arc-shaped structure and prevent the angle structure from jamming the wire harness and hindering the extraction of the wire harness.

[0012] The extension of the slot on the board surface provides a larger space for the lead-out of the wire harness and is beneficial to the limitation of the wire harness when it is led out. If the extension length is too large, the impact on the strength of the board surface will also become greater, which is not conducive to the assembly and use of the board surface. Therefore, preferably, the extension length of the slot on the board surface is less than 1 / 4 of the diameter of the board surface. If the extension length is too small, it will hinder the lead-out of the wire harness. Therefore, it is further preferred that the extension length of the slot on the board surface is greater than the width of the flange at the periphery of the panel.

[0013] Preferably, the opening of the notch is provided with a wire harness lead-out margin, the wire harness lead-out margin is the spacing between the opening width of the notch and the width of the wire harness in the panel, and the wire harness lead-out margin is provided to make the wire harness easier to lead out. Further preferably, the spacing between the wire harness lead-out margin is 3 to 5 mm.

[0014] Preferably, the groove passes through the board surface in the thickness direction. Such an arrangement can provide the maximum space for the extraction of the wire harness. Moreover, since part of the board surface is penetrated, the two sides of the board surface at the penetration point can be relatively deformed. This deformable space also provides a release source for the stress generated during the assembly of the board surface.

[0015] The keypad back plate is provided with the notch structure described in any of the above technical solutions.

[0016] A gas water heater comprises a keypad back plate adapted to be installed with the keypad, wherein the keypad back plate is provided with a notch structure as described in any of the above technical solutions.

[0017] In summary, the technical solution described in the utility model has the following main beneficial effects:

[0018] Compared with the prior art, the technical solution of the utility model can reduce the impact on the strength of the board surface, and can also avoid other components arranged on the board surface, and the layout is more reasonable.

[0019] At the same time, the length, width and height settings of the slot can optimize the wiring harness export and prevent the wiring harness from being pulled and interfering with each other during assembly.

[0020] Further or more detailed beneficial effects will be described in detail in conjunction with specific examples in the specific implementation manner. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The present invention is further explained with reference to the following embodiments:

[0030] The core technical problem faced by the technical solution of the embodiment of the present application comes from the inventor's accurate understanding of the prior art. Therefore, how to prevent the groove from interfering with other components on the board and minimize the impact of the groove on the strength of the board are technical problems that the inventor urgently needs to solve.

[0031] At the same time, optimizing the derivation of the wire harness and preventing the pulling and mutual interference of the wire harness during assembly are also technical problems that the inventors are trying to solve simultaneously.

[0037] Specifically, the panel a is provided with reinforcing ribs a-1 radiating to the periphery, and the slot structure includes a slot 1, which is provided at the edge of the panel a and opened at the extension trajectory of one of the reinforcing ribs a-1 on the panel a. In this embodiment, in addition to being able to guide the wiring harness, the slot 1 can also reduce the impact on the strength of the panel a with the help of the reinforcing ribs a-1. Furthermore, since other components on the panel a need to be separated from the reinforcing ribs a-1, the slot 1 follows the extension trajectory of the reinforcing ribs and can avoid other components arranged on the panel a, making the layout more reasonable.

[0038] As a preferred embodiment, refer to the attached Figures 2-3 One end of the slot is adjacent to the end of the reinforcing rib a-1, so that the reinforcing rib a-1 can be extended as much as possible, and form a partial guide and limit for the wire harness leading out slot 1. In this embodiment, an arc-shaped wire harness guide portion 1-1 is provided at one end of the slot 1 adjacent to the reinforcing rib a-1. The wire harness guide portion 1-1 can also further guide the wire harness through its arc-shaped structure. When the wire harness is led out, the arc-shaped structure can also prevent the wire harness from pulling and interfering with each other.

If the length L is too large, the strength of the board a will be further reduced, which is not conducive to the assembly and use of the board a. If the length L is too small, it will hinder the derivation of the wire harness.

[0040] In this embodiment, the opening width of the slot 1 is Figure 3 The width marked W includes the wire harness lead-out allowance. The wire harness lead-out allowance is the spacing of the opening width of the slot 1 that is larger than the width of the wire harness in the panel a, which can make the wire harness easier to lead out. The spacing of the wire harness lead-out allowance is 4 mm.

[0041] As a preferred embodiment, refer to the attached Figures 2 to 4 , the height of slot 1 is Figure 4In the mark h, the slot 1 passes through the edge of the panel a, so that the height h of the slot 1 reaches the maximum, which can provide the maximum space for the wiring harness to be led out, and the penetration point can undergo relative deformation, which also provides a release source for the stress generated during the assembly of the panel a.

[0042] The embodiment further provides a keypad back panel b, on which a notch structure in any of the above embodiments is arranged.
