[0066] Hereinafter, embodiments of the present application will be described in detail with reference to the accompanying drawings.

[0067] As attached Figures 1 to 3 As shown, in an illustrative embodiment of the rooftop machine of the utility model, the rooftop machine includes: a body 100, a partition 200, a first heat exchanger, a second heat exchanger, a bracket 400, a fan 600, a side air outlet 101, a lower air outlet 102 and a sealing plate 300; wherein the partition 200 is arranged in the body 100 and divides the interior of the body 100 into an indoor side and an outdoor side.

[0073] When the lower air outlet 102 is closed by the sealing plate 300, the air conditioning wind output by the fan 600 is input into the room through the side air outlet 101. The side air outlet 101 or the lower air outlet 102 can be selected according to the actual needs of the user, thereby improving the applicability of the rooftop unit.

[0074] Furthermore, the fan 600 is installed through the plug-in portion 900 , and the angle of the fan 600 facilitates installation while ensuring the air volume.

[0075] In some embodiments, the air outlet direction of the fan 600 is the depth direction of the air outlet of the fan 600 .

[0076] In some embodiments, the angle between the depth direction of the air outlet of the fan 600 and the bottom wall of the body 100 is α, and the angle of α satisfies 50°≤α. Through this design, the angle between the air outlet direction of the fan 600 and the bottom wall of the body 100 is not less than 50°. In this way, while ensuring that the fan 600 is conveniently installed on the bracket 400, the airflow output by the fan 600 can be blown between the side air outlet 101 and the lower air outlet 102, ensuring that the airflow output through the side air outlet 101 is similar to the airflow output through the lower air outlet 102.

[0082] And because the motor has a certain weight, the center of gravity of the motor can be firmly maintained above the bracket 400 at this angle, avoiding the center of gravity of the fan 600 from shifting, causing installation inconvenience, or causing a gap between the air outlet of the fan 600 and the bracket 400 due to the weight of the motor after long-term use.

[0083] In some embodiments, the fan 600 is a centrifugal fan, and the fan 600 includes a housing and a heat exchange fan disposed inside the heat exchange fan. The air outlet 600 of the fan 600 is the air outlet of the housing.

[0122] So that a plug-in channel is formed between the first bending section 901, the second bending section 902 and the mounting surface 500. The plug-in board 700 is plugged into the plug-in channel, and two sides of the plug-in board 700 are respectively attached to the second bending section 902 and the mounting surface 500.

[0123] In some embodiments, the first bending section 901 is perpendicular to the mounting surface 500 from the direction away from the bottom of the body 100, and the second bending section 902 is vertically disposed on a side of the first bending section 901 away from the mounting surface 500. The second bending section 902 extends toward the connection port.

[0124] In some embodiments, the distance between the second bending section 902 and the mounting surface 500 is not less than the thickness of the plug board 700, so that the plug board 700 can be inserted into the plug channel.

[0125] In some embodiments, the distance between the second bending section 902 and the mounting surface 500 is equal to the thickness of the plug-in board 700, so that the plug-in board 700 can be just inserted into the plug-in channel, so that the air outlet of the fan 600 is tightly connected to the mounting surface 500, and the air outlet of the fan 600 is connected to the connecting port to avoid air leakage due to gaps between the air outlet of the fan 600 and the mounting surface 500.

[0126] In some embodiments, the distance between the second bending section 902 and the mounting surface 500 is the thickness of the second bending section 902 plus 0.5 mm. With this design, the structure is reasonable, and the process of bending the first bending section 901 and the second bending section 902 is more convenient, which is easy to manufacture.

[0127] In some embodiments, the second bending section 902 is bent on one side close to the side air outlet 101 in a direction away from the mounting surface 500 to form a guide portion 903, so as to further facilitate the alignment of the plug board 700 with the corresponding plug channel and facilitate the insertion of the plug board 700.

[0128] In some embodiments, a limit member 120 is provided on the mounting surface 500, and a lever 110 is provided at the air outlet of the fan 600. When the lever 110 contacts the limit member 120, the air outlet of the fan 600 is connected to the connection port. The limit member 120 contacts the lever 110 to limit the position of the fan 600, so as to prevent the fan 600 from moving relative to the mounting surface 500, thereby improving the stability of the connection.

[0129] In some embodiments, the lever 110 is disposed on the side of the air outlet of the fan 600 close to the side air outlet 101. After the fan 600 is installed on the bracket 400, because the mounting surface 500 is inclined and the side close to the side air outlet 101 is higher, the fan 600 will slide toward the side away from the side air outlet 101. Therefore, when the lever 110 contacts the limiting member 120, the limiting member 120 prevents the lever 110 and the fan 600 from sliding downward together, thereby limiting the fan 600.

[0130] In some embodiments, the stopper 120 is detachably connected to the mounting surface 500. When the stopper 120 is not needed, the stopper 120 can be removed separately.

[0131] In some embodiments, the stopper 120 is disposed at one side of the connection port close to the side air outlet 101. The stopper 120 is detachably connected to the mounting plate 401 by bolts, which are commonly used standard parts and are easy to install.

[0132] Please refer to all the drawings. In some embodiments, the plug board 700 is formed by bending the air outlet of the fan 600 outward, thereby improving the strength of the structure and reducing the cost.

[0133] In some embodiments, the plug board 700 is detachably connected to the casing of the fan 600 and can be replaced or removed as needed.

[0134] In some embodiments, a through slot is formed on the mounting plate 401, and the stopper 120 is used to pass through the through slot and then be connected to the mounting plate 401 by bolts. During installation, the stopper 120 can be inserted from the air supply channel for easy installation.

[0135] In some embodiments, after the fan 600 is installed on the bracket 400, the limiting member 120 is connected to the lever 110 by bolts to further improve the stability of the connection.

[0136] In some embodiments, a baffle 800 is provided on a side of the connection port away from the side air outlet 101 , and the fan 600 is blocked by the baffle 800 .

[0137] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations of the present invention. Ordinary technicians in the field can change, modify, replace and modify the above embodiments within the scope of the present invention.
