Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to a rooftop unit. Background Art

[0002] Among air conditioners, rooftop units are favored by the market because of their integrated internal and external units and easy installation. Rooftop units are generally installed on the top of a house. Due to the differences in roof layout and indoor air duct structure, various requirements are put forward for the air outlet position of rooftop units. Under the premise of compact structure, it is difficult to meet multiple air outlet and return modes at the same time, and there will be difficulties in poor wind field.

[0003] Housing structures are quite diverse. The air ducts on the roofs of some houses are vertical, and rooftop units with downward air outlet are more convenient to install. Some are horizontal, and lateral air outlet is more suitable. At the same time, due to the different layouts of the roofs, the installation and placement of rooftop units are also restricted, and sometimes there is a dilemma of not being able to select the air outlet direction. When the above situation occurs, the installer must further lengthen the connecting air duct, bend it and guide it to the reserved position on the roof, which makes the installation difficult and the cost increased. At the same time, air ducts with multiple turns are prone to cause air volume attenuation, which affects the customer's experience. Therefore, it is particularly necessary to design a modular rooftop unit that can be flexibly switched according to customer needs.

[0004] In summary, the installation of the rooftop unit in the prior art cannot flexibly switch the air outlet direction, resulting in installation difficulties. Summary of the invention

[0025] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but they are not intended to limit the present invention.

[0026] See also Figures 1 to 5 As shown, according to an embodiment of the present invention, a rooftop unit is provided, comprising a chassis module 10 and a fan module 20, wherein the chassis module 10 has at least two installation positions A of the same specification; the fan module 20 is detachably connected to the installation position A; the rooftop unit can be configured with different air outlet directions, and in the internal structure configuration of the rooftop unit with different air outlet directions, the fan module 20 is installed at the corresponding installation position A in an adapted air outlet direction.

[0027] The rooftop machine of the present invention first sets a plurality of installation positions of the same specifications on the chassis module for installing the internal parts, so as to meet the installation requirements of multiple internal parts of the same specifications. In addition, the fan module is modularly designed, and the modular fan modules are the same in installation specifications, and can be installed in any installation position according to the air outlet direction and provide the fan blowing function. In this way, when the rooftop machine needs to adjust the side air outlet or the bottom air outlet, the staff only needs to adjust the internal structure of the rooftop machine, change the flow direction of the air duct, and install the fan module in a position suitable for the corresponding air outlet direction to change the air outlet direction of the rooftop machine. The air outlet direction can be switched by adjusting inside the rooftop machine, which is not restricted or affected by the external environment or the housing structure at all, and the specific installation method can be flexibly selected, which greatly reduces the difficulty of installation and improves the versatility of the rooftop machine.

[0028] The rooftop machine further includes an air duct module 30 , which is detachably connected to the corresponding installation position A; the air duct module 30 is used in conjunction with the fan module 20 .

[0030] The air duct module 30 is also designed as a modular structure, and its installation specifications match the installation position. Whether it is the screw position or the connecting component, it can be quickly and accurately connected to the installation position A. Preferably, the fan module and the air duct module are close to a rectangle or square in size specifications, which is convenient for internal space planning. Of course, the modular shape can also be selected in other shapes, which can be determined and selected according to the internal space of the rooftop machine.

[0031] Preferably, see Figure 4 and Figure 5 The rooftop machine also includes a switching module 40, which is detachably connected to the installation position A, and the fan module 20 can be selectively connected to the installation position A through the switching module 40.

[0032] The adapter module 40 can make the fan module more sealed and more stable when it is connected to the installation position A at a certain position. The adapter module 40 itself is also modularly designed and can be installed at the required position, which increases the flexibility of switching the air outlet direction. Since the lower air outlet can be set to multiple and the side air outlet can also be set to multiple, there are more combinations to choose from when adjusting the internal structure and installation position of the rooftop unit, so the adapter module 40 is needed to play a vital connection and transition role in the installation and matching process.

[0033] The rooftop machine further includes a sealing module 50 , which is adapted to the air outlet direction and installed at the air outlet that needs to be sealed. The sealing module 50 is detachably connected to the installation position A.

[0034] The sealing module 50 is used to further seal the internal air duct to ensure that the air output of the rooftop unit is not affected. While flexibly switching the air output direction, it ensures sufficient air output and cooling and heating efficiency to improve user satisfaction.

[0038] Figures 1 to 5 The process of the rooftop unit switching from side air outlet to bottom air outlet is shown. Figure 1The rooftop unit is equipped with a side air outlet structure. When the configuration of the lower air outlet needs to be switched, the lower air duct module 40 is first removed, and then the sealing module 40 at the second installation position A2 is removed. Figure 2 Finally, the fan module 20 is removed from the first installation position A1. If necessary, the side panel where the side air outlet B2 is located can be removed to facilitate internal adjustment, installation and removal. Figure 3 Then the adapter module 40 is connected to the second installation position A2 and sealed to the chassis module 10, and then the fan module 20 is installed on the adapter module 40, as shown. Figure 4 Remove the air duct module 30, leave the first installation position A1 empty, seal the sealing module 50 at the side air outlet B2, and finally complete the structure configuration of the rooftop unit's lower air outlet, as shown in FIG. Figure 5 shown.

[0039] Preferably, the adapter module 40 and the second installation position A2 are sealed by a seal 60. A separate seal 60 is selected to seal the connection gap of the adapter module 40, mainly considering that it can be flexibly selected and adjusted according to specific needs. The position and matching shape of the adapter module can have multiple situations at the second installation position A2, and the specific shape of the seal 60 can be selected according to the situation and needs. For example, the seal 60 can be a rubber ring, multiple sets of sealing pads, etc.

[0040] In this embodiment, a reinforcement beam 11 is provided on the chassis module 10 , and the reinforcement beam 11 is detachably connected to a corresponding structure.
