[0002] At present, air conditioners are household appliances commonly used in people's daily lives. With the continuous development of technology, in order to improve the comfort of users, air conditioners using microporous air outlets are gradually promoted and used. For example: Chinese patent application No. 2018100328211 discloses a microporous air guide plate, an air outlet panel and an air conditioner cabinet, that is, a number of micropores are arranged on the air guide plate, and the airflow output by the air conditioner is blocked by the air guide plate and output through the micropores. However, in actual use, the airflow output by the air conditioner will generate greater wind resistance after being blocked by the air guide plate. In order to ensure that the micropores can output the airflow to form a breeze to ensure the air output, the speed of the fan needs to be increased accordingly. This increases the energy consumption of the air conditioner on the one hand, and on the other hand, it will also generate greater noise that affects the user experience. How to design an air conditioning technology with low energy consumption and low noise is a technical problem to be solved by the present invention. Summary of the invention

[0028] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] like Figure 1-Figure 5 As shown, the air conditioner generally includes a housing 100 and a heat exchanger (not shown) and a fan arranged in the housing 100. Under the action of the fan, the outside air is sucked into the housing 100 and heat-exchanged with the heat exchanger, and finally the heat-exchanged air is output to the outside from the air outlet portion on the housing 100. The housing 100 is generally provided with an air outlet window to install the air outlet assembly 200. The air outlet assembly 200 in this embodiment increases the air outlet volume and reduces energy consumption and noise while meeting the requirements of micro-pore air outlet. The specific structural form of the air outlet assembly 200 is as follows.

[0030] The air outlet assembly 200 includes: an air inlet plate 11, an air outlet plate 12 and a speed increasing tube 2. The air inlet plate 11 is provided with a plurality of air inlet holes 111, and the air outlet plate 12 is provided with a plurality of air outlets 121; the interior of the speed increasing tube 2 is formed with a first air duct 21 and a second air duct 22 connected along the gas flow direction, the cross-sectional size of the first air duct 21 gradually decreases, and the cross-sectional size of the second air duct 22 gradually increases. The outer port of the first air duct 21 forms an air inlet area, and the outer port of the second air duct 22 forms an air outlet area. The tube wall of the speed increasing tube 2 is provided with an air suction hole 23 connected to the second air duct 22. The speed increasing tube 2 is arranged between the air inlet plate 11 and the air outlet plate 12, and the air introduced by the air inlet hole 111 enters the speed increasing tube 2 and is output from the corresponding air outlet 121.

[0031] Specifically, the air outlet assembly 200 forms a plurality of air inlet holes 111 on the air inlet plate 11, wherein the size of the air inlet holes 111 meets the size requirements of microporous air supply and is not limited here. The air in the housing 100 of the air conditioner is blown toward the air inlet plate 11 after heat exchange with the heat exchanger, and the air is formed into an airflow flowing toward the air outlet plate 12 by the air inlet holes 111. The airflow output from the air inlet holes 111 first enters the speed increasing tube 2 during the flow process, and the two air ducts formed inside the speed increasing tube 2 first contract and then gradually expand. During the flow of the airflow in the first air duct 21, the cross-sectional size of the first air duct 21 gradually decreases, thereby increasing the flow velocity of the airflow; finally, the airflow velocity entering the second air duct 22 is faster, and the cross-sectional size of the second air duct 22 gradually increases, then the Venturi principle can be used to generate low pressure in the air inlet section of the second air duct 22 to produce adsorption. The wall of the speed-increasing tube 2 is provided with an air suction hole 23 connected to the second air duct 22. Under the low pressure of the air inlet section of the second air duct 22, the air outside the speed-increasing tube 2 can enter the speed-increasing tube 2 through the air suction hole 23. In this way, the air output can be effectively increased without increasing the fan speed. In order to allow the air suction hole 23 to well inhale the air outside the speed-increasing tube 2, the air suction hole 23 is close to the connection between the first air duct 21 and the second air duct 22. In this way, the adsorption force generated by the high-speed airflow output from the first air duct 21 as soon as it enters the second air duct 22 is strong, and the air can be better inhaled through the air suction hole 23. In order to ensure the smooth flow of the airflow in the speed-increasing tube 2, the connection between the first air duct 21 and the second air duct 22 is smoothly transitioned.

[0032] Among them, the outside of the speed increasing tube 2 is also provided with an air guide sleeve 24, which is sleeved on the outside of the speed increasing tube 2 and shielded on the outside of the air suction hole 23, the inner port of the air guide sleeve 24 is connected to the outer tube wall of the speed increasing tube 2, and the outer port of the second air duct 22 extends to the outside of the outer port of the air guide sleeve 24. Specifically, the air guide sleeve 24 is sleeved on the outside of the speed increasing tube 2, and the outside air passes through the area between the outer port of the air guide sleeve 24 and the speed increasing tube 2 and enters the area between the air guide sleeve 24 and the speed increasing tube 2, and is finally sucked into the second air duct 22 through the air suction hole 23. Since the outer port of the second air duct 22 extends to the outside of the outer port of the air guide sleeve 24, the influence of the air sucked from the outer port of the air guide sleeve 24 on the airflow output from the second air duct 22 can be reduced.

[0033] In addition, an air inlet gap is formed between the air guide sleeve 24 and the air outlet plate 12. Since the outer port of the second air duct 22 is close to the air outlet plate 12, the air flow output from the second air duct 22 can be smoothly output to the outside from the air outlet 121. However, since the outer port of the air guide sleeve 24 is far away from the air outlet plate 12, the air inside the air outlet plate 12 can be sucked in through the air inlet gap.

[0034] Further, in order to facilitate assembly, the air outlet assembly also includes an annular enclosure 13, which is arranged between the air inlet plate 11 and the air outlet plate 12, and the annular enclosure 13, the air inlet plate 11 and the air outlet plate 12 form a shell 1, and the speed increasing tube 2 is installed in the shell 1. Specifically, during assembly, the shell 1 can be installed in the air outlet window of the shell 100 to facilitate modular assembly, thereby improving assembly efficiency. In order to meet the air suction requirements of the air suction hole 23 in the shell 1, a plurality of ventilation holes 112 are also provided on the air inlet plate 11, and the aperture of the ventilation hole is smaller than the aperture of the air inlet hole 111. After the heat exchanged air is blown to the air inlet plate 11, part of the air enters the speed increasing tube 2 through the air inlet hole 111, and part of the air will enter the internal cavity of the shell 1 through the ventilation hole. The gas entering the internal cavity of the shell 1 can be sucked into the second air duct 22 by the air suction hole 23. At the same time, under the action of the air guide sleeve 24, since the outer port of the air guide sleeve 24 faces the air outlet 121, a small amount of external air can be sucked into the air guide sleeve 24 from the edge of the air outlet 121 to form mixed wind.

[0035] Furthermore, the air outlet assembly also includes a ventilation pipe 3, which is arranged between the air inlet plate 11 and the air outlet plate 12; the ventilation pipe 3 is fixed on the air inlet plate 11 and connected to the corresponding air inlet hole 111, and the speed increasing pipe 2 is fixed on the air inlet plate 11 and connected to the corresponding air inlet hole 111; the annular enclosure 13 is fixed on the air inlet plate 11, and the air outlet plate 12 is rotatably mounted on the annular enclosure 13. Specifically, the ventilation pipe 3 is only used to convey the airflow introduced from the air inlet hole 111, so that the user can adjust it according to the air volume. When a large air volume is required, the air outlet plate 12 is rotated so that the air outlet 121 is arranged relative to the speed increasing pipe 2, so as to achieve a large air volume output from the air outlet 121. When the user needs a small air volume, the air outlet plate 12 is rotated so that the air outlet 121 is arranged relative to the ventilation pipe 3, so that a small air volume can be delivered. Among them, the air outlet plate 12 is a circular structure, and the inner wall of the annular enclosure 13 is provided with an annular groove (not marked), and the air outlet plate 12 is rotatably arranged in the annular groove. The air outlet plate 12 can rotate in the annular groove, and the rotation method can be manually rotated by the user. At this time, the air outlet plate 12 can be provided with a handle to facilitate the user to rotate. At the same time, the air outlet plate 12 can also be driven electrically. For example: the inner surface circumference of the air outlet plate 12 is provided with a gear ring, and the housing 1 is provided with a motor, and the rotating shaft of the motor is provided with a gear meshing with the gear ring to realize the automatic rotation of the air outlet plate 12. The specific rotation adjustment method of the air outlet plate 12 is not limited here.

[0036] 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.
