[0020] The present invention will be described in detail below through specific embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. However, it should be noted that the specific embodiments described below do not limit the technical solution. Those skilled in the art can make further technical extensions under the guidance of the following technical solutions. The scope of protection of this patent application is determined by the claims.

[0021] Example 1: Combined with Appendix Figure 1 As shown, a vertical exposed fan coil unit with a detachable core and shell structure includes an inner core frame 6, and a fan unit 2 is provided at the bottom of the inner core frame 6; a filter screen 11 is also provided at the bottom of the fan unit 2 to filter the airflow entering the device.

[0022] The upper part of the fan unit 2 is equipped with a water pan. There are two water pans, namely the lower water pan 3 and the upper water pan 7. The upper water pan 7 is set close to the bottom of the finned heat exchanger 4. The lower water pan 3 is externally connected and is equipped with an external drain pipe and a connector to drain the condensate generated by the finned heat exchanger 4.

[0023] The inner core frame 6 is provided with a fixing frame 63 on the top. In this embodiment, a locking hole 64 is provided through the center of the fixing frame. The locking hole 64 is used to lock and fix the outer shell 1.

[0024] In this embodiment, an outer shell frame is provided inside the outer shell 1, and a crossbeam 12 is provided on the top of the outer shell frame. Locking points that match the fixing bracket 63 are provided on the crossbeam 12. Figure 2 As shown, the outer shell 1 and the inner core frame 6 are fixed by the locking point and the locking hole 64. With the above structural design, after the outer shell 1 and the inner core frame 6 are fixed, the exposed screw points of the riveting affect the appearance. This invention further improves upon this by providing an air outlet grille 5 on the top of the outer shell 1, and a movable cover structure on the air outlet grille 5, such as... Figure 6As shown, the air vent grille 5 is a split design, including a central fixed part 52 and two side hinged parts 53. The side hinged parts 53 are hinged to the central fixed part 52 and fixed together. The locking point between the crossbeam 12 and the fixing frame 63 is located below one of the side hinged parts 53. The control panel 55 is embedded in the other side hinged part 53 for use as a control component. This structure allows the side hinged parts 53 to act as movable covers, enabling flexible coverage and exposure of the locking point.

[0025] With the above structural design, this utility model separates the outer shell 1 from the inner core frame 6 before installation. The finned heat exchanger 4 is inclinedly arranged inside the inner core frame, which seals off the vertical space of the entire inner core frame 6, maximizing heat exchange efficiency. The finned heat exchanger 4 has an inlet connector 42 and a return connector 41 on its side.
