Specific embodiments

[0021] The present invention will be described in detail below with reference to the drawings and in conjunction with embodiments. It should be noted that, without conflict, the embodiments in the present invention and the features in the embodiments can be combined with each other.

[0022] As Figures 1 to 6 In an embodiment of the air outlet self - adapting high - large - space air conditioner of the present invention as shown, on the body 1, there are successively arranged from top to bottom a heat exchange chamber 2, an axial flow fan 3 for driving air flow, and an air outlet 4; on the side wall of the heat exchange chamber 2, there are provided a plurality of air inlets 21 and a filter screen 22 for filtering the air flowing in through the air inlets 21; inside the heat exchange chamber 2, there is a heat exchanger 23 disposed between the air inlet 21 and the axial flow fan 3; on the air outlet 4, there is an air outlet regulator 5 for adjusting the air outlet; the air outlet regulator 5 includes a lower air deflector 51 fixed on the air outlet 4 and having a plurality of flow through openings 53, and an upper air deflector 52 that can rotate to block the air flow through the flow through openings 53; the upper air deflector 52 is fixed on the output shaft of the temperature sensor actuator 54; on the lower air deflector 51, there is an air guiding plate 514 arranged to incline upwards. The two air deflectors controlled to open and close by a temperature sensor can timely adjust the air outlet direction of the air outlet according to the refrigeration or heating mode, effectively ensuring the efficient transmission of air flow in the heating mode and the full diffusion in the refrigeration mode, ensuring the full guidance and utilization of air flow, and achieving the effect of energy conservation and environmental protection.

[0023] Specifically, the air outlet 4 and the axial flow fan 3 are coaxially arranged.

[0024] Specifically, the heat exchange chamber 2 is designed in a square shape; the air inlets 21 are respectively arranged on the four side walls of the heat exchange chamber 2; the heat exchanger 23 is designed in a Q - shape horizontally surrounding the inner wall of the heat exchange chamber 2. By arranging a plurality of air inlets and a surrounding heat exchanger, it is ensured that under the condition of the same air output, the air intake of a single air inlet is reduced, the risk of water leakage caused by the condensate water of the heat exchanger being blown away is reduced, and the efficient heat exchange of air flow is achieved, improving the heat exchange efficiency of the equipment.

[0025] Specifically, a "return" - shaped water receiving tray 24 is provided below the heat exchanger 23; on the water receiving tray 24, there is a drain pipe 25 connecting to the outside.

[0026] Specifically, a rubber and plastic insulation cotton layer is provided on the outer wall of the water receiving tray 24.

[0027] Specifically, a rubber-plastic thermal insulation cotton layer is adhered to the inner wall of the body 1 .

[0028] Specifically, the axial flow fan 3 is an outer rotor axial flow fan with an air guide tube.

[0029] Specifically, the air outlet 4 is provided with a horizontally arranged cross frame 41; a temperature-sensing actuator 54 is fixed to the cross frame 41; the lower air guide blade 51 includes an outer ring 511, an inner ring 512, and a plurality of connecting rods 513 spaced apart to connect the inner ring 512 and the outer ring 511; an air guide plate 514 is fixed to one side of the connecting rod 513 and tilted upward; the upper air guide blade 52 has the same structure as the lower air guide blade 51; the lower surface of the upper air guide blade 52 is closely attached to the upper surface of the lower air guide blade 51. By having two air guide blades that fit together and can rotate relative to each other, in conjunction with the temperature-sensing actuator, the diffusion direction of the airflow can be timely guided in the cooling and heating modes, achieving efficient airflow distribution in the cooling and heating modes, further improving the air conditioning effect.

[0030] Specifically, the number of the air guide plates 514 is six.

[0031] Working principle: After the staff installs the equipment in the factory, they select a heat source or cold source with a suitable temperature according to the ambient temperature and connect it to the heat exchanger 23. In the heating mode, the heat exchanger 23 is connected to the heat source. Driven by the axial flow fan 3, the surrounding air flows from the air inlet 21 through the filter and the aluminum fin type heat exchanger 23, and then flows downward from the inner cavity formed by the Q-shaped heat exchanger enclosure. The airflow temperature reaching the air outlet 4 is relatively high. The temperature sensing actuator 54 drives the upper guide blade 52 to overlap with the lower guide blade 51, and the airflow forms a vortex at a higher wind speed. Rotating downward, the wind speed decay is reduced, and the hot air flow is efficiently transmitted to the working area on the ground; in cooling mode, the heat exchanger 23 is connected to the cold source, and the temperature of the air flow reaching the air outlet 4 is relatively low. The temperature sensing actuator 54 drives the upper guide blade 52 to rotate and separate from the lower guide blade 51. Under the guidance of the inclined air guide plate 514, the air flow is first blown out and diffused horizontally, and then naturally distributed downward, ensuring the cooling efficiency of the working area, ensuring sufficient cooling area, and reducing the risk of the cold air flow directly sinking to the ground and being blocked by equipment in a narrow diffusion area.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
