[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative efforts are within the protection scope of the present utility model.

[0028] In this article, relational terms such as the terms "first" and "second" are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. The orientation or positional relationship indicated by "up", "down", "left", "right", "top", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation of the present utility model.

[0029] As Figure 4 shown, when installing an electric heater in the prior art, it is usually necessary to separately connect a power cord to the electric heater, which is separate from the power cord of the whole machine. There is a problem of low installation wiring efficiency. A protection device needs to be added in the engineering circuit, and multiple wire passing holes need to be reserved on the whole machine for the electric heater to route the wire.

[0030] Specifically, in the prior art, an upper wire passing bracket 20 for installing engineering wiring is provided below the electrical box 3 component, and the air supply fan is located in the lower second cavity 2. When a customer selects an electric heater, the electric heater is usually installed on the side wall of the air supply duct, and a bottom wire passing bracket 19 for routing the power cord is provided nearby.

[0031] Figure 4 The figure shows the wiring schematic of a conventional model. With the above settings, two power lines need to be provided for engineering installation, which are connected to the electrical box 3 component and the electric heater through the upper wire passing bracket 20 and the bottom wire passing bracket 19 respectively. Therefore, the conventional wiring structure is relatively complex, with a large installation difficulty and prone to wiring misoperation.

[0032] Embodiment 1:

[0033] As Figures 1 to 3 shown, a rooftop unit with convenient wiring includes a first cavity 1 and a second cavity 2. An electrical box 3 is arranged in the first cavity 1, and a transfer box 4 is arranged in the second cavity 2. The transfer box 4 is connected to the electrical box 3 through a first connecting wire 5, and the transfer box 4 is also provided with a second connecting wire 7 for connecting an optional accessory 6.

[0034] By designing a transfer box 4 inside the rooftop unit, the transfer box 4 is connected to the electrical box 3, and a second connecting wire 7 for connecting the optional accessory 6 is arranged on the transfer box 4. Connecting the engineering power line to the transfer box 4 can realize the power-on of the electrical box 3 and the optional accessory 6. When installing the optional accessory after-sales, the optional accessory 6 is connected to the transfer box 4 through the second connecting wire 7. Therefore, the above structure reduces the internal wiring of the rooftop unit, thereby reducing the risk of misoperation. When installing the optional accessory 6, there is no need to additionally configure a power line, improving the installation efficiency.

[0035] Specifically, during production, a power line connecting the electrical box 3 component and the optional accessory 6 is pre-buried in the transfer box 4. During use, only the engineering power line needs to be connected to the transfer box 4, reducing the setting of wire passing brackets and wire passing holes and simplifying the overall structure of the rooftop unit.

[0036] Specifically, the optional accessory 6 in this application can be an electric heater or other devices.

[0037] In the rooftop unit with convenient wiring of this embodiment, an intermediate partition 8 is arranged between the first cavity 1 and the second cavity 2. The first connecting wire 5 penetrates through the intermediate partition 8, and a first wire passing hole is opened on the intermediate partition 8.

[0038] The intermediate partition 8 is arranged to separate the first cavity 1 and the second cavity 2. At the same time, the intermediate partition 8 supports the components in the first cavity 1, improving the overall stability of the rooftop unit. The first wire passing hole is arranged to facilitate the passing of the first connecting wire 5 between the transfer box 4 and the electrical box 3, realizing the connection between the electrical box 3 and the transfer box 4 inside the rooftop unit.

[0039] In the rooftop unit with convenient wiring of this embodiment, a baffle group is arranged on the intermediate partition 8, and the baffle group is located on the periphery of the first wire passing hole to block the first wire passing hole.

[0040] Specifically, the first connecting line 5 runs upward from the adapter box 4, passes through the first wire passing hole on the middle partition plate 8, and accesses from the bottom of the electrical box 3 component. A baffle group is arranged at the position of the first wire passing hole to block the first wire passing hole to prevent water leakage, which can effectively prevent the first connecting line 5 from contacting water due to rain on the first wire passing hole, thus avoiding potential safety hazards.

[0041] In the rooftop unit with convenient wiring of this embodiment, the baffle group includes a first baffle 9 and a second baffle 10 that are snap-connected to each other. The first baffle 9 is fixedly connected to the middle partition plate 8, and the second baffle 10 is detachably connected to the middle partition plate 8.

[0042] Specifically, the baffle group includes two spliced baffles to prevent water leakage. Among them, the first baffle 9 and the middle partition plate 8 are fixedly connected by welding, and the second baffle 10 is detachable. When assembling the wiring of the whole machine, the second baffle 10 is not assembled first to ensure sufficient space for wiring operation. The first connecting line 5 passes through the first wire passing hole from the second cavity 2 to the first cavity 1. After the wiring is completed, the second baffle 10 is installed back to block the periphery of the first wire passing hole. The cooperation of the two baffles is convenient for installation.

[0043] In the rooftop unit with convenient wiring of this embodiment, the first baffle 9 includes a first vertical plate 11 and a first flat plate 12 that are perpendicular to each other. A first bending plate is arranged on the side of the first flat plate 12 away from the first vertical plate 11.

[0044] With the above settings, the first baffle 9 is in an inverted U shape. The first flat plate 12 forms the top cover plate, and the first vertical plates 11 and the first bending plates on both sides block the sides, improving the shielding and sealing effect of the first wire passing hole. Specifically, the height of the first vertical plate 11 is greater than the height of the first bending plate, which is convenient for wiring operation during assembly and facilitates the installation of the second baffle 10 from the side close to the first bending plate to achieve splicing with the first baffle 9, reducing the assembly difficulty.

[0045] In the rooftop unit with convenient wiring of this embodiment, the second baffle 10 includes a second vertical plate 13 and a third vertical plate 14 that are perpendicular to each other. The second vertical plate 13 is arranged opposite to the first vertical plate 11, and a second bending plate 15 that abuts against the first vertical plate 11 is arranged at the end of the third vertical plate 14.

[0046] Specifically, the second baffle 10 is in an overall Z shape and is fixed below the first flat plate 12. The outer surface of the second vertical plate 13 fits with the inner surface of the first bending plate, and the second bending plate 15 fits with the first vertical plate 11, and they are respectively detachably installed by screws.

[0047] In the rooftop unit with convenient wiring of this embodiment, the middle partition plate 8 includes an inclined plate portion. The baffle group is installed on the inclined plate portion, and the side of the baffle group close to the inclined plate portion fits with the inclined plate portion.

[0048] The inclined plate part is arranged to facilitate drainage. The first vertical plate 11, the first bending plate, and the side of the second vertical plate 13 close to the inclined plate part are all inclined, so as to ensure close fitting with the middle partition 8, thereby improving the shielding effect on the first wire passing hole.

[0049] In the roof machine with convenient wiring of this embodiment, a second wire passing hole is provided on the side of the adapter box 4 close to the electrical box 3. A column is provided on one side of the adapter box 4, and a third wire passing hole 16 is provided on the column.

[0050] Specifically, a second wire passing hole leading to the components of the electrical box 3 is reserved in the adapter box 4, which cooperates with the first wire passing hole to facilitate the routing of the first connecting wire 5. The column and the third wire passing hole 16 are provided to facilitate the engineering power line to penetrate the second cavity 2 and access the adapter box 4 to realize power supply.

[0051] Preferably, the adapter box 4, the electrical box 3, and the optional accessory 6 are all installed on the same side of the roof machine, ensuring that the wiring operations are all on the same side of the whole machine, and avoiding affecting the installation operation due to installation environment limitations.

[0052] In the roof machine with convenient wiring of this embodiment, a wiring board 17 and a fuse tube 18 are arranged in the adapter box 4. The electrical box 3 is electrically connected to the wiring board 17 and the fuse tube 18, and the optional accessory 6 is electrically connected to the wiring board 17 and the fuse tube 18.

[0053] By arranging the wiring board 17 and the fuse tube 18 in the adapter box 4, it is convenient for wiring, and at the same time provides multiple protections to ensure the safety of the product.

[0054] Specifically, in this application, the first cavity 1 is a condensation cavity, and the second cavity 2 is an evaporation cavity. The condensation cavity is located above the evaporation cavity to ensure the normal use and operation of the roof machine. An independent adapter box 4 is designed in the evaporation cavity, and a wiring board 17 and a fuse tube 18 are arranged in the adapter box 4. All the wires connecting from the wiring board 17 and the fuse tube 18 to the components of the electrical box 3 are completed before leaving the factory; the wires connecting from the wiring board 17 and the fuse tube 18 to the electric heater are also pre-buried. A wire passing hole column is arranged on the side of the adapter box 4. During use, only the engineering power line needs to be connected to the wiring board 17.

[0055] In the roof machine with convenient wiring of this embodiment, a sealing part is arranged around the port of the second connecting wire 7 close to the optional accessory 6, and the sealing part is fixedly installed on the periphery of the adapter box 4.

[0056] Specifically, at one end of the second connecting wire 7 connected to the electric heater, the wire head port is sealed with a heat shrinkable tube and fixed near the installation position. When the electric heater is selected and distributed after-sales, loosen the port of the pre-buried wire and connect the electric heater.

[0057] Embodiment 2:

[0058] In the roof-mounted unit with convenient wiring of this embodiment, other structures are set in the same way as in Embodiment 1, except for the following parts:

[0059] As Figure 5 and Figure 6 shown, the adapter box 4 is detachably connected to the whole roof-mounted unit, and the adapter box 4 is installed outside the whole roof-mounted unit.

[0060] The adapter box 4 is set outside the whole roof-mounted unit. The corresponding first connecting wire 5 accesses the electrical box 3 in the condensation cavity from the outside through the wire passing hole on the upper wire passing bracket 20, and the second connecting wire 7 accesses the electric heater in the evaporation cavity from the outside through the bottom wire passing bracket 19. The engineering power cord is directly connected to the adapter box 4 from the outside; it is set to be detachably connected and located outside the roof-mounted unit, which is convenient for overhaul and maintenance of the adapter box 4 and improves the installation flexibility.

[0061] On the other hand, the present application also proposes an air-conditioning unit, including a roof-mounted unit with convenient wiring according to any one of the above embodiments.

[0062] It can be anticipated that the air-conditioning unit in the present application includes all the beneficial effects of the roof-mounted unit with convenient wiring in the above embodiments, which will not be elaborated here.
