[0029] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0030] Combination Figure 1-4 As shown, this embodiment of the present disclosure provides an air conditioner including: a body 100, a first air duct housing 200, and a second air duct housing 300. The body 100 has an air inlet 101 on its rear side and a through hole 102 on its top. A first air outlet 103 is provided within the through hole 102. A second air outlet 104 is provided on the left side wall of the body 100, and a third air outlet 105 is provided on the right side wall of the body 100. The input end of the first air duct housing 200 is connected to the air inlet 101, and the output end of the first air duct housing 200 is connected to the first air outlet 103. The input end of the second air duct housing 300 is connected to the air inlet 101, the first output end of the second air duct housing 300 is connected to the second air outlet 104, and the second output end of the second air duct housing 300 is connected to the third air outlet 105.

[0031] Using the air conditioner provided in this embodiment, indoor air enters the unit 100 through the air inlet 101, then exits from the front of the unit 100 through the first air outlet 103 in the through hole 102, exits from the left side of the unit 100 through the second air outlet 104, and exits from the right side of the unit 100 through the third air outlet 105. The airflow has relatively multiple directions and covers a relatively large area, thus improving the efficiency of indoor heat exchange.

[0032] Understandably, the side of the machine 100 facing away from the wall and towards the user is the front side, the side of the machine 100 facing the wall and away from the user is the rear side, the side of the machine 100 located to the right of the user is the right side, and the side of the machine 100 located to the left of the user is the left side.

[0033] Understandably, the connection between the input end of the first air duct housing 200 and the air inlet 101 means that the airflow at the air inlet 101 enters the body 100 and then enters the input end of the first air duct housing 200 from within the body 100. Similarly, the connection between the input end of the second air duct housing 300 and the air inlet 101 means that the airflow at the air inlet 101 enters the body 100 and then enters the input end of the second air duct housing 300 from within the body 100.

[0034] Combination Figure 4 and Figure 5 As shown, optionally, a first fan 210 is provided inside the first air duct housing 200, and the first fan 210 is fixedly connected to the inner sidewall of the first air duct housing 200. Thus, when the first fan 210 is started, it can drive the airflow inside the first air duct housing 200 to accelerate towards the first air outlet 103. The airflow at the first air outlet 103 is blown into the through hole 102, increasing the airflow velocity and the air delivery distance.

[0035] Understandably, when the first fan 210 starts, a negative pressure is formed inside the first air duct housing 200, which draws the air that enters the machine body 100 from the air inlet 101 into the first air duct housing 200 through the input end of the first air duct housing 200.

[0036] Optionally, a second fan 310 is provided inside the second air duct housing 300, and the second fan 310 is fixedly connected to the inner wall of the second air duct housing 300. When the second fan 310 is activated, it drives the airflow within the second air duct housing 300 to accelerate towards the second air outlet 104 and the third air outlet 105. The airflow is then delivered into the room from the left and right sides of the unit 100 through the second air outlet 104 and the third air outlet 105, increasing the airflow speed and delivery distance, improving air circulation efficiency, and making the indoor temperature more uniform.

[0037] Optionally, the heights of the second air outlet 104 and the third air outlet 105 are both lower than the height of the first air outlet 103. In this way, the first air outlet 103 delivers air from the top to the front, creating a high-level airflow guide, while the second air outlet 104 and the third air outlet 105 deliver air from the left and right sides at a lower level, creating a multi-directional, three-dimensional airflow pattern. This combination of high and low air outlets helps reduce blind spots in airflow, enhances the effect of indoor airflow, and further improves indoor temperature uniformity and comfort.

[0038] Optionally, the flow rate of the air inlet 101 is greater than the sum of the flow rates of the first air outlet 103, the second air outlet 104, and the third air outlet 105. In this way, the flow rate of the air inlet 101 can meet the air intake requirements of the first air outlet 103, the second air outlet 104, and the third air outlet 105 simultaneously, avoiding the risk of limited airflow or turbulent noise due to insufficient air intake, ensuring a smooth and stable air delivery process, and improving the overall quiet operation and energy efficiency of the unit.

[0039] Optionally, a filter 110 is provided at the air inlet 101. In this case, the airflow entering through the air inlet 101 contains a significant amount of dust, hair, and other impurities. With prolonged use, this increases the risk of blockage inside the unit 100. The filter 110 effectively intercepts airborne particles, reducing the risk of dust accumulation inside the unit 100, decreasing the frequency of cleaning, and improving the user experience.

[0040] Optionally, a grille 120 is provided at the air inlet 101, and a filter 110 is located between the grille 120 and the second air duct housing 300. In this way, the grille 120 can provide support and obstruction for the interior of the air inlet 101, and provide lateral obstruction and support for the components inside the housing 100.

[0041] Optionally, the top of the unit 100 is provided with a first cylinder 130 and a second cylinder 140. The first cylinder 130 is located in front of the second cylinder 140. The first cylinder 130 and the second cylinder 140 together enclose a through hole 102, and the gap between the first cylinder 130 and the second cylinder 140 forms a first air outlet 103. In this way, the first cylinder 130 and the second cylinder 140 cooperate to form a stable airflow guiding structure, making the indoor airflow more concentrated as it flows through the through hole 102. The airflow blown out of the first air outlet 103 mixes with the indoor airflow in the first cylinder 130, forming a mixed airflow with a relatively low temperature difference from the room temperature, reducing the discomfort caused by direct airflow.

[0042] Optionally, a first air duct housing 200 is fitted over the outer side of the first cylinder 130 and the second cylinder 140. In this way, the first air duct housing 200, fitted over the outer side of the first cylinder 130 and the second cylinder 140, provides guidance and constraint for the airflow blown out of the first air outlet 103, so that the airflow flows smoothly and evenly into the first cylinder 130 along the first air duct housing 200.

[0043] Specifically, the first air duct housing 200 has an annular shell structure. In this way, both the first cylinder 130 and the second cylinder 140 are cylindrical structures, and the annular shell-shaped first air duct housing 200 can better adapt to the first cylinder 130 and the second cylinder 140.

[0044] Specifically, the front end of the first air duct housing 200 is sleeved with the rear end of the first cylinder 130, and the rear end of the first air duct housing 200 is sleeved with the front end of the second cylinder 140. In this way, the connection stability is relatively high, providing a stable guiding channel for the airflow of the first air outlet 103.

[0045] Combination Figure 6 , Figure 7 and Figure 8 As shown, optionally, a third air duct housing 400 is provided inside the body 100. The third air duct housing 400 is located below the second air duct housing 300. The input end of the third air duct housing 400 is connected to the air inlet 101, the first output end of the third air duct housing 400 is connected to the second air outlet 104, and the second output end of the third air duct housing 400 is connected to the third air outlet 105. In this way, the airflow at the air inlet 101 enters the body 100, and then enters the interior of the third air duct housing 400 from the body 100. The airflow is then discharged from the second air outlet 104 from the first output end of the third air duct housing 400, and from the third air outlet 105 from the second output end of the third air duct housing 400. This achieves independent control of multiple air outlets, meeting the air supply needs in different scenarios.

[0046] Optionally, two second air outlets 104 and two third air outlets 105 are provided. The second air duct housing 300 is correspondingly configured with one of the second air outlets 104 and one of the third air outlets 105, and the third air duct housing 400 is correspondingly configured with the other second air outlet 104 and the other third air outlet 105. In this way, air can be supplied to different height areas vertically, covering the air supply needs of different height areas and improving the uniformity and comfort of air supply.

[0047] Optionally, a third fan 410 is installed inside the third air duct housing 400, and the third fan 410 is fixedly connected to the inner wall of the third air duct housing 400. When the third fan 410 is started, it can drive the airflow inside the third air duct housing 400 to accelerate towards the second air outlet 104 and the third air outlet 105. The airflow is then delivered into the room from the left and right sides of the unit 100 through the second air outlet 104 and the third air outlet 105, increasing the airflow speed and delivery distance, improving air circulation efficiency, and making the indoor temperature more uniform.

[0048] Optionally, the flow rate at the front end of the through hole 102 is greater than the flow rate at the rear end of the through hole 102. In this way, since the airflow in the room and the airflow at the first air outlet 103 converge at the front end of the through hole 102, the flow rate at the front end of the through hole 102 is relatively large, which can accommodate more airflow and reduce the risk of turbulence and increased energy loss caused by sudden changes in flow rate.

[0049] Optionally, a guide vane 150 is provided inside the first air outlet 103. The guide vane 150 is used to guide the airflow at the first air outlet 103 towards the front of the unit 100. In this way, by setting the guide vane 150, the airflow at the first air outlet 103 is guided to blow towards the front of the unit 100. This makes the airflow direction more concentrated, reduces the risk of airflow turbulence, and also allows indoor air to be better drawn in through the through hole 102 and mixed with the airflow at the first air outlet 103, reducing the temperature difference with the room temperature and improving the gentleness and comfort of the airflow.

[0050] Optionally, the air guide plate 150 is connected to the unit body 100. In this way, by setting the air guide plate 150, the airflow at the first air outlet 103 is guided towards the front of the unit body 100. This makes the airflow direction more concentrated, reduces the risk of airflow turbulence, and also allows for better intake of indoor air through the through-hole 102 and mixing with the airflow at the first air outlet 103, reducing the temperature difference with room temperature and improving the gentleness and comfort of the airflow.

[0051] Optionally, the front end of the air guide plate 150 gradually narrows. This tapered structure effectively guides the airflow along the axial direction of the air guide plate 150, reducing airflow diffusion and eddy current generation, resulting in more concentrated and smoother airflow. The inclined surface of the tapered structure also guides the mixed airflow through a smooth transition, further reducing wind resistance and noise, and improving overall air delivery efficiency.

[0052] Specifically, the air guide plate 150 has a conical cylindrical structure, and the flow rate at the front end of the air guide plate 150 is less than the flow rate at the rear end of the air guide plate 150. This design, where the flow rate at the front end of the air guide plate 150 is less than the flow rate at the rear end, causes the airflow to gradually contract as it passes through the air guide plate 150, effectively increasing the airflow velocity, enhancing the concentration of the exhaust air, and suppressing the generation of turbulence.

[0053] Optionally, multiple air guide plates 150 are provided and spaced apart along the axial direction of the through hole 102. Each air guide plate 150 is fixedly connected to a connecting rod 151, and the connecting rod 151 is fixedly connected to the body 100. In this way, the number of air guide plates 150 is large, and they are spaced apart within the first air outlet 103, covering a large area of ​​the first air outlet 103. This allows for more uniform airflow guidance, making the airflow direction more concentrated and the distribution more uniform, further reducing the risk of airflow turbulence and improving the airflow mixing effect.

[0054] Optionally, when multiple air guide plates 150 are provided, each air guide plate 150 is fixedly connected to a connecting rod 151, and the connecting rod 151 is connected to the body 100. In this way, multiple air guide plates 150 are stably connected to the body 100 through the connecting rod 151, ensuring that the air guide plates 150 maintain a fixed position during operation, reducing the risk of displacement of the air guide plates 150 due to vibration or airflow impact, thereby maintaining the stability and reliability of airflow guidance.

[0055] Specifically, multiple connecting rods 151 are provided, and these connecting rods 151 are spaced apart circumferentially along the air guide plate 150. This results in a relatively large number of connecting rods 151 and multiple connection points with the air guide plate 150, allowing for multi-point support at different locations on the air guide plate 150. This further reduces the risk of displacement of the air guide plate 150 due to vibration or airflow impact. Furthermore, the spaced-apart arrangement of multiple connecting rods 151 along the circumferential direction of the air guide plate 150 ensures structural strength while minimizing obstruction of airflow, thus guaranteeing smooth and uniform airflow.

[0056] Specifically, there are two air guide vanes 150. With the two air guide vanes 150 working together, the coverage area of ​​the first air outlet 103 is larger, allowing for more even airflow guidance, more concentrated airflow direction, further reducing the risk of airflow turbulence, improving airflow mixing, and enhancing the user experience.

[0057] Optionally, the air guide plate 150 and / or the connecting rod 151 may be made of plastic. In this way, the connecting rod 151 and the air guide plate 150, made of plastic, possess good insulation and corrosion resistance, while also being lightweight, reducing the overall weight.

[0058] Optionally, multiple air guide vanes 150 and multiple connecting rods 151 are integrally formed. This integrally formed structure simplifies the assembly process, improves production efficiency, and enhances the structural strength and stability of the connection, effectively avoiding airflow deviation caused by assembly errors.

[0059] Specifically, the connecting rod 151 is fixedly connected to the second cylinder 140. Thus, since the gap between the first cylinder 130 and the second cylinder 140 forms the first air outlet 103, and the air guide plate 150 is located at the first air outlet 103, the connection between the connecting rod 151 and the second cylinder 140 is relatively short. This requires less material, which helps reduce manufacturing costs, and the connection structure is more compact.

[0060] Optionally, the minimum diameter of the air guide plate 150 is larger than the diameter of the inner wall of the second cylinder 140. In this way, the diameter of the air guide plate 150 is relatively large, the flow rate of the air guide plate 150 is relatively large, and the air flow rate that can be carried is relatively large, which facilitates the convergence and thorough mixing of indoor air and the airflow blown out of the first air outlet 103.

[0061] Optionally, a cover plate 160 is provided at both the second air outlet 104 and the third air outlet 105. In this way, the cover plate 160 can cover the second air outlet 104 and the third air outlet 105, reducing the risk of external dust entering the interior of the second air duct housing 300 when indoor heat exchange is not required.

[0062] Understandably, the cover plate 160 and the body 100 can be connected using conventional methods such as snaps, screws, or magnetic attraction.

[0063] Understandably, the cover 160, by covering the second air outlet 104 and the third air outlet 105, can also reduce the risk of external dust entering the interior of the third air duct housing 400.

[0064] Optionally, multiple covers 160 are provided and respectively disposed on opposite sides of the body 100. Each cover 160 is used to cover one second air outlet 104 or one third air outlet 105. In this way, the multiple covers 160 correspond to the two second air outlets 104 and the two third air outlets 105. By covering the second air outlets 104 and the third air outlets 105 with the covers 160, the risk of external dust entering the interior of the second air duct housing 300 and the third air duct housing 400 is reduced when indoor heat exchange is not required.
