[0021] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with an embodiment. The embodiment is only used to explain the present invention and does not constitute a limitation on the protection scope of the present invention.

[0022] according to Figure 1 , 2 As shown in Figures 3, 4 and 5, a condensing reheat dehumidification operating room air conditioner is proposed in this embodiment, including an air-conditioning main unit 1, a bellows 2 and a return duct 4. The air-conditioning main unit 1 is connected to the bellows 2 through the return duct 4. An exhaust plate 3 is provided at the lower end of the bellows 2, and a diffuser 5 is provided at the lower port of the exhaust plate 3. The air-conditioning main unit 1 and the bellows 2 are common central air conditioners with condensing reheating function, and their working principle will not be explained in detail.

[0023] The diffuser 5 includes a rectangular cover 6 and a conical flow guide 8. The rectangular cover 6 is fixedly connected to the lower end of the exhaust plate 3. The conical flow guide 8 is placed in the center of the rectangular cover 6. At least two metal rods 10 are provided on the outside of the conical flow guide 8. The two ends of the metal rods 10 are respectively fixedly connected to the outer wall of the conical flow guide 8 and the inner wall of the rectangular cover 6; the conical flow guide 8 is fixed to the center of the rectangular cover 6 by the metal rods 10, that is, below the exhaust port at the lower end of the exhaust plate 3.

[0024] A plurality of guide frames 7 are provided between the rectangular cover 6 and the conical guide member 8. Intervals are left between the conical guide member 8 and the guide frame 7, between the rectangular cover 6 and the guide frame 7, and between two adjacent guide frames 7 to allow airflow to pass through. A fixing device is provided at the upper end of the guide frame 7, and the guide frame 7 is detachably connected to the metal rod 10 through the fixing device. The airflow blown out from the lower end of the exhaust plate 3 will be discharged outward through the diffuser 5. The conical guide member 8 and each guide frame 7 in the rectangular cover 6 will guide the airflow, and by controlling the flow direction and mixing degree of the fluid, the heat storage performance is optimized and the blown air is evenly distributed.

[0025] The guide frames 7 are stacked on top of each other. When cleaning the guide frames 7, the lock between the guide frames 7 and the metal rods 10 is released by the fixing device, and the guide frames 7 can be removed from between the rectangular cover 6 and the conical guide member 8 in turn, which is convenient for replacement and maintenance.

[0026] About the guide frame 7: The guide frame 7 is a rectangular frame, and each guide frame 7 is connected in sequence from top to bottom, and the cross section of the guide frame 7 is rectangular. The outward side and the inward side of the guide frame 7 are both smooth inclined surfaces. The wind entering the rectangular cover 6 will be discharged through the interval between the conical guide member 8 and the guide frame 7, the rectangular cover 6 and the guide frame 7, and the interval between two adjacent guide frames 7. Each guide frame 7 will divide the wind direction of the air outlet into multi-directional flow to ensure uniform airflow distribution.

[0027] About the fixing device: the fixing device includes a rubber jacket 12, the lower end of the rubber jacket 12 is fixedly connected to the upper end of the guide frame 7, and the upper end of the rubber jacket 12 is provided with a clamping groove 13, and the clamping groove 13 is engaged with the metal rod 10 sleeve. In order to prevent the metal rod 10 from falling off from the clamping groove 13, a pin positioning member is provided on the inner side of the clamping groove 13 for limiting the metal rod 10 from escaping from the clamping groove 13.

[0028] Specifically, the pin positioning member includes spherical pins 16 disposed on both sides of the metal rod 10, the spherical pins 16 are fitted with the upper end surface of the metal rod 10, and the end of the spherical pin 16 away from the metal rod 10 is placed in a pin groove 14 provided in the groove wall of the clamping groove 13, the pin groove 14 is slidably connected to the spherical pin 16, and a spring 15 is disposed in the pin groove 14, and the spring 15 is fixedly connected to the spherical pin 16. After the rubber clamp 12 is completely clamped on the outside of the metal rod 10, the spherical pin 16 will pop out of the pin groove 14, and the metal rod 10 is limited from the upper end of the metal rod 10.

[0029] The guide frame 7 has a certain weight. After being fixed to the lower end of the metal rod 10 by a clamping sleeve, the guide frame 7 still has the risk of falling off even under the limit of the pin positioning member. Based on this, a magnetic attraction member 17 is provided on the inner side of the rubber jacket 12, and the magnetic attraction member 17 is attracted to the metal rod 10. The use of magnetic attraction fixing can further improve the safety of the guide frame 7 after assembly.

[0030] In order to facilitate the staff to determine the fixed position of each guide frame 7, two limiting rings 11 are provided on the top of each guide frame 7. The limiting rings 11 are sleeved on the outside of the metal rod 10. The limiting rings 11 are fixedly connected to the metal rod 10, and a gap is left between the two metal rods 10 to allow the rubber jacket 12 to be inserted. After the rubber jacket 12 is fixed to the metal rod 10, the two limiting rings 11 will limit the rubber jacket 12 from both sides of the rubber jacket 12, so that the rubber jacket 12 will not slide left and right along the metal rod 10.

[0031] In addition, a plurality of electric heating wires 9 are provided at the upper end of the rectangular cover 6, and the electric heating wires 9 are placed above the conical guide member 8 and the guide frame 7, and both ends of the electric heating wires 9 are fixedly connected to the inner wall of the rectangular cover 6. When the airflow is blown out through the rectangular cover 6, if the weather is cold, the electric heating wires 9 can be turned on to assist in heating the air and keep the air dry.

[0032] Working principle: The airflow blown out from the lower end of the exhaust plate 3 will be discharged outward through the diffuser 5. The conical guide 8 and each guide frame 7 in the rectangular cover 6 will guide the airflow, and optimize the heat storage performance and evenly distribute the blown air by controlling the flow direction and mixing degree of the fluid. Each guide frame 7 is stacked on top of each other. When cleaning the guide frame 7, the lock between the guide frame 7 and the metal rod 10 is released by the fixing device, and each guide frame 7 can be removed from between the rectangular cover 6 and the conical guide 8 in turn, which is convenient for replacement and maintenance.
