DETAILED DESCRIPTION

[0026] The following is a detailed description of a fresh air enthalpy difference room temperature and humidity control device provided by the utility model in combination with the accompanying drawings and specific embodiments. At the same time, it is explained here that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art may also adopt other alternative methods to implement some known technologies; and the accompanying drawings are only for a more specific description of the embodiments, and are not intended to specifically limit the utility model.

[0027] like Figure 1 , Figure 3 and Figure 4 As shown, an embodiment of the utility model provides a fresh air enthalpy difference room temperature and humidity control device, including: an air handling cabinet body 1, the outer wall of the air handling cabinet body 1 is rotatably connected to a frame 2, the inner cavity of the frame 2 is rotatably connected to a grille 3, a handle groove 8 is provided in the middle above the outer wall of the frame 2, a fixing groove 12 penetrating the frame 2 is provided in the middle of the top of the handle groove 8, a handle body 9 is slidably connected to the inner cavity of the handle groove 8, a stop block 11 is fixedly installed in the middle of the top of the handle body 9, and a third spring 10 is symmetrically installed on the top of the handle body 9 and on both sides of the stop block 11, an installation groove 5 corresponding to the fixing groove 12 is provided on the outer wall of the air handling cabinet body 1, and the end of the third spring 10 away from the handle body 9 is fixedly connected to the top of the handle groove 8, and the handle body 9 is limited by the third spring 10, so that the handle body 9 moves too far to prevent the stop block 11 from being separated from the inner cavity of the fixing groove 12, and at the same time, a position for placing fingers can be reserved at the bottom of the handle body 9.

[0028] A second spring 6 is fixedly connected to the inner cavity of the mounting groove 5 , and an insert block 7 is fixedly connected to the other end of the second spring 6 .

[0029] like Figure 1 and Figure 6 As shown, installation cavities 4 are provided on both sides below the outer wall of the frame 2, the inner cavity of the installation cavity 4 is fixedly connected with a first spring 41, the other end of the first spring 41 is fixedly connected with a latch 42, the top of the outer wall of the latch 42 is fixedly connected with a handle 43, and the outer wall of the frame 2 is provided with a slide groove 44 adapted to the handle 43, by pulling the handle 43 to drive the latch 42 to retract into the installation cavity 4, the latch 42 is separated from the air handling cabinet body 1, so that the frame 2 can be completely removed from the air handling cabinet body 1, which is convenient for cleaning the frame 2 and maintaining the interior of the air handling cabinet body 1.

[0030] like Figure 4 and Figure 5 As shown, the insert block 7 and the stop block 11 are both inserted into the inner cavity of the fixing groove 12 when the frame 2 is closed, and the positions of the insert block 7 and the stop block 11 correspond to each other, so that the insert block 7 can be pushed out when the stop block 11 moves upward.

[0031] like Figure 1 and Figure 5 As shown, a folding cloth 13 is fixedly provided on the top of the handle body 9, and the other end of the folding cloth 13 is fixedly connected to the top of the handle groove 8.
