[0002] The heat dissipation motor of the cooling module of the refrigeration range hood is arranged inside the cooling module. The working temperature inside the cooling module is above 60℃. The hot air heats the heat dissipation motor and its control module, which will affect the performance of the heat dissipation motor and reduce the heat dissipation air volume. Therefore, it is necessary to install the driver board of the heat dissipation motor outside the heat dissipation module to prevent the driver board from overheating and affecting the performance of the heat dissipation motor, but the installation and fixing method of the driver board needs to be solved. At present, the installation and fixing of the driver board is usually first packaged in a plastic box, and then the plastic box is fixed on the mounting seat. It requires multiple production processes and multiple screws to fix it. The production process is complicated and the production cost is high. In addition, the installation and fixing of the driver board can also be integrated into the electronic control board, but the integration of the driver board on the electronic control board requires the external dimensions of the electronic control board to increase, which affects the layout and requires higher installation space for the electronic control board. In addition, the compatibility requirements of the electronic control board are very high. The integrated driver board on the electronic control board is not universally compatible with the electronic control boards of other models. A separate new electronic control board needs to be added, which increases the management cost. Utility Model Content

[0014] Compared with the prior art, the utility model has the advantages that the wiring bracket of the wiring structure for the range hood has an input terminal, an output terminal and a wiring area, and the wiring area is divided into a first wiring groove and a second wiring groove. The first connecting wire enters the first wiring groove from the input terminal and is led out from the output terminal, and the second connecting wire enters the second wiring groove from the input terminal and is led out from the output terminal and merges with the first connecting wire. Thus, the first connecting wire and the second connecting wire can be routed separately through the parallel first and second wiring grooves to avoid mutual interference. For example, the first connecting wire can be a heat dissipation motor wire of the driving board, and the second connecting wire can be a wiring harness such as an internal motor wire, a swing fan motor wire, and a sensor wire of the range hood, so as to avoid the second connecting wire scratching components on the driving board and causing damage to the driving board.

[0019] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0020] like Figures 1 to 4 As shown, the wiring structure for the range hood of this embodiment includes a wiring bracket 100, the wiring bracket 100 has an inlet terminal 1, an outlet terminal 3 and a wiring area 2 arranged between the inlet terminal 1 and the outlet terminal 3, and the wiring area 2 is divided into a first wiring groove 21 and a second wiring groove 22 by a vertical partition 212. A first connecting line 4 and a second connecting line 5 that merge are provided upstream of the inlet terminal 1, the first connecting line 4 enters the first wiring groove 21 from the inlet terminal 1 and then leads out from the outlet terminal 3, the second connecting line 5 enters the second wiring groove 22 from the inlet terminal 1 and then leads out from the outlet terminal 3, and the first connecting line 4 and the second connecting line 5 are led out from the outlet terminal 3 and then merge.

[0021] The first wiring groove 21 has an installation area 23, and the installation area 23 is used to install the drive board 6 of the heat dissipation motor of the range hood. The input line and the output line of the drive board 6 constitute the first connecting line 4. The input line of the drive board 6 is connected to the heat dissipation motor (not shown in the figure), and the output line of the drive board 6 is connected to the electric control board (not shown in the figure). A first wire pressing buckle 24 is provided between the installation area 23 and the input terminal 1, and a second wire pressing buckle 25 is provided between the installation area 23 and the output terminal. After the first wire pressing buckle 24 and the second wire pressing buckle 25 are provided, the first connecting line 4 can be prevented from deviating from the first wiring groove 21. In addition, in order to facilitate the insertion of the first connecting line 4, the tops of the first wire pressing buckle 24 and the second wire pressing buckle 25 have a one-way guide surface 26 for inserting the first connecting line 4. The drive board connecting wire, i.e., the first connecting wire 4, enters the wire pressing buckle and first contacts the one-way guide surface 26. The wire pressing buckle is elastically deformed under force to facilitate the connecting wire to be inserted into the wire pressing buckle. Due to the use of the one-way guide surface 26, there is no guide in the disengagement direction of the wire pressing buckle. After entering the wire pressing buckle, it is difficult for the first connecting wire 4 to disengage, thereby preventing the first connecting wire 4 from deviating from the first wiring groove 21.

[0022] The opposite sides of the installation area 23 are respectively provided with a buckle 28 and a spring buckle 29, and the drive plate 6 is installed in the installation area 23 by means of the buckle 28 and the spring buckle 29. The buckle 28 and the spring buckle 29 have a limiting rib 210, and the spring buckle 29 has a guiding inclined surface 211 for facilitating the introduction of the drive plate 6 into the spring buckle 29. After the drive plate 6 is installed, it is clamped on the buckle 28 and the spring buckle 29, and abuts against the limiting rib 210, so that the limiting is more reliable. The buckle 28 and the spring buckle 29 are used to install and position the drive plate 6, and the installation structure is simple and the installation efficiency is high, and the fixing screws are omitted, thereby reducing the production cost. In addition, in order to support the drive plate 6, a supporting boss 27 is provided in the installation area 23.

[0023] The second connecting wires 5 running in the second wiring groove 22 are connecting wires such as the internal motor wire, the swing fan motor wire and the temperature sensor wire. After the first wiring groove 21 is separated from the second wiring groove 22, the above-mentioned second connecting wires 5 can be prevented from scratching the components on the driving board 6, thereby causing damage to the driving board 6.

[0024] In this embodiment, the top of the second wiring groove 22 has an upper baffle 221 for preventing the second connecting wire 5 from escaping from the second wiring groove 22 .
