Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be arbitrarily combined with each other.

[0029] This application provides an electrical control box 100 for fan coil units, such as... Figures 1-3 As shown, the electrical control box 100 includes a box body 4 and a first-layer electrical control board 1 and a second-layer electrical control board 2 installed inside the box body 4. The first-layer electrical control board 1 and the second-layer electrical control board 2 are spaced apart, and the second-layer electrical control board 2 is located on the side of the first-layer electrical control board 1 where electrical components are installed. The first-layer electrical control board 1 and the second-layer electrical control board 2 can each be configured to include one electrical control board or multiple electrical control boards.

[0030] The solution provided in the embodiments of this application saves the area occupied by the electrical control board by arranging it in layers within the box 4, thereby reducing the installation area of ​​the electrical control box 100 and enabling the electrical control box to be installed adaptably on the fan coil unit. The fan coil unit is a terminal component of the air conditioning system, including a fan and coil structure. The fan coil unit is a device known to those skilled in the art and will not be described in detail here.

[0031] In one embodiment, the box body 4 includes a box body having an opening, and the box body 4 may further include a cover for sealing the opening. Figures 1-3 The image shows the main body of the housing with the control board installed, but the cover is not shown. The second control board 2 is closer to the opening than the first control board 1. The second control board 2 includes at least one flip control board configured to flip towards the opening of the housing. This allows the flip control board to be flipped to expose the electrical components on the first control board 1 to the operator when they need to be replaced or repaired, thus facilitating replacement or repair.

[0032] exist Figures 1-3 In one embodiment, the first layer electronic control board 1 and the second layer electronic control board 2 are each provided with an electronic control board, and the electronic control board in the second layer electronic control board 2 is configured as a flip electronic control board.

[0033] In another embodiment, the second layer control board 2 may be provided with multiple control boards, some of which are configured to be flip-able relative to the first layer control board 1. In this case, easily damaged components on the first layer control board 1 can be positioned corresponding to the flip-able control boards in the second layer control board 2.

[0034] In another embodiment, the multiple control boards of the second layer control board 2 can be configured as flip control boards that can be flipped relative to the first layer control board 1. For the location of the component on the first layer control board 1 that needs to be repaired or replaced, the flip control board at the corresponding location can be flipped.

[0035] In one embodiment, a third control board 3 can be installed on the side of the flip control board opposite to the first control board 1, further making the installation structure of the control board more compact. Since the third control board 3 can flip along with the flip control board, the third control board 3 will not hinder the maintenance of the components on the first control board 1.

[0036] Therefore, the solution provided by the embodiments of this application, by setting the flip-up control board in the second layer control board 2 to be flippable, can facilitate the operator to repair or replace the electrical components on the first layer control board 1.

[0037] Understandably, the second-layer control board 2 can also be fixedly installed as a whole on the housing 4, meaning the second-layer control board 2 cannot be flipped. For example, both sides of the second-layer control board 2 can be fixed to the housing 4 with bolts. When maintenance of the first-layer control board 1 is required, the control board on the second-layer control board 2 can be removed, and after maintenance, it can be reinstalled. To facilitate the maintenance of electrical components, easily damaged electrical components can be placed on the second-layer control board 2.

[0038] In one embodiment, one side of the flip control board is rotatably mounted to the main body of the box via a pivot, and the other side is detachably fixed to the main body of the box. The other side of the flip control board can be fixed to the main body of the box by bolts or snap-fits. When it is necessary to flip the flip control board, the other side of the flip control board is detached from the box, thereby enabling the flipping.

[0039] In one embodiment, the flip-up control board is configured to flip up and down or left and right when the control box is installed on the fan coil unit.

[0040] exist Figures 1-3 In this embodiment, the main body of the box 4 includes a back panel 41 for mounting towards the fan coil unit and side panels 42 surrounding the back panel 41, with the side panels 42 forming an opening in the main body of the box. In this embodiment, the box 4 has a square structure and four side panels 42 are provided. In other embodiments, the box 4 may also have other shapes.

[0041] In one example, the pivot of the flip control board in the second layer control board 2 is installed on the side plate 42 on one side of the main body of the box, and the end of the flip control board away from the pivot is detachably fixed to the side plate 42 on the other side of the main body of the box by means of bolts or snap-fit. Figure 2 In the example, a fixing plate 7 is fixed on the side of the flip control board away from the rotating shaft. The fixing plate 7 can be fixed to the side plate 42 by bolts, thereby fixing the side of the flip control board away from the rotating shaft to the box body.

[0042] The electrical control box 100 is typically installed on the side of the fan coil unit 200. In this case, the back panel 41 of the box body 4 is vertically mounted facing the side of the fan coil unit 200. Figure 6 and Figure 7 The state shown. When the pivot of the flip control board is set on the left or right side plate 42, the flip control board can flip left and right. When the pivot of the flip control board is set on the upper or lower side plate 42, the flip control board can flip up and down.

[0043] exist Figure 1In the example, a connecting plate 5 is installed on the side plate 42 on one side of the box body 4. One or more hinges 6 are provided between the connecting plate 5 and the flip control plate. The flip control plate is flipped by the hinges 6. The connecting plate 5 can be a bent structure, for example, it can be set as a Z-shaped bent structure. This bent structure can facilitate the connection with the hinges 6 and the side plate 42.

[0044] This embodiment provides a connecting plate 5 between the side plate 42 and the flip control board. The shape of the connecting plate 5 allows the flip control board to be easily connected to the side plate for flipping. Furthermore, by providing a hinge 6 with a pivot on the connecting plate 5, the flipping angle of the flip control board can be increased compared to providing the pivot directly on the side plate 42.

[0045] In one embodiment, the box body 4 is also provided with an air inlet 421 and an air outlet 411. When the electrical control box 100 is installed on the fan coil unit 200, the air outlet 411 corresponds to the return air outlet 201 of the fan coil unit 200. When the fan in the fan coil unit 200 draws air from the return air outlet 201, it can draw out the hot airflow in the electrical control box 100, which helps to cool the electrical control box 100 quickly.

[0046] exist Figures 1-3 In the example, the back panel 41 of the housing 4 is vertically mounted facing the side of the fan coil unit 200, and the air outlet 411 is located on the back panel 41. The air inlet 421 can be located on the side panels 42 on the left and right sides of the housing 4, and the air inlet 421 is located below the air outlet 411. In this way, the airflow entering the housing 4 from the lower air inlet 421 can flow through the control board and then flow out from the air outlet 411, which can more effectively remove the heat inside the control box 100.

[0047] To prevent dust from entering the air inlet 421, a dust cover 8 can be installed on the outside of the side plate 42 to cover the air inlet 421. An opening 81 can be provided at the lower end of the dust cover 8, through which airflow enters the air inlet 421.

[0048] Furthermore, in the solution provided in this application, the air inlet 421 is located on the left and right sides of the box 4, rather than at the bottom of the box 4. In this way, when a fire occurs in the electrical control box, the flames inside the electrical control box can be prevented from falling from the air inlet 421, thereby preventing a larger fire from breaking out.

[0049] A heat sink 11 can also be installed on the first layer of the electrical control board 1 to dissipate heat from the first layer of the electrical control board 1. A high-power electrical component can be installed on the first layer of the electrical control board 1, and the heat sink 11 can be installed on the high-power electrical component on the first layer of the electrical control board 1.

[0050] like Figures 1-3In the example shown, the radiator 11 is positioned below the air outlet 411, so that the airflow entering from the lower air inlet 421 can flow upward through the radiator and then out of the air outlet 411, thereby carrying away the heat from the radiator 11.

[0051] Embodiments of this application also provide a fan coil unit, such as... Figure 6 and Figure 7 As shown, the device includes a fan coil unit 200 and an electrical control box 200 as described above, which is installed on the fan coil unit 200. In this embodiment, the electrical control box 200 is installed on the side of the fan coil unit 200.

[0052] Embodiments of this application also provide an air conditioning system, including the fan coil unit as described above.
