[0039] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0040] Combination Figure 1 As shown, the embodiment of the present disclosure provides an air conditioner, comprising: an air outlet duct 100 and a guide plate 200. The air outlet duct 100 has a turning section 110, one end of which is an air inlet 101, and the other end of which is an air outlet 102, and the angle between the air inlet direction of the air inlet 101 and the air outlet direction of the air outlet 102 is a poor angle; the guide plate 200 is arranged in the turning section 110, and has the same bending direction as the turning section 110.

[0041] With the air conditioner provided by the embodiment of the present disclosure, since the guide plate 200 is disposed in the turning section 110, the guide plate 200 provides guidance for the airflow passing through the turning section 110 and avoids disturbance between the airflows on both sides of the guide plate 200, thereby reducing the air volume loss when the airflow direction changes, and improving the performance of the air conditioner. Moreover, the bending direction of the guide plate 200 is the same as the bending direction of the turning section 110, so that the flow direction of the airflow in the turning section 110 is consistent with the flow direction of the airflow guided by the guide plate 200, so that the flow of the airflow is smoother.

[0042] It can be understood that a minor angle refers to an angle greater than 0° and less than 180°. Right angles, acute angles and obtuse angles are collectively referred to as minor angles.

[0043] Specifically, the angle between the air inlet direction of the air inlet 101 and the air outlet direction of the air outlet 102 is 90°. In this way, the air conditioner sends cold air into the room through the air outlet duct. Since the angle between the air inlet direction of the air inlet 101 and the air outlet direction of the air outlet 102 is 90°, the air outlet 102 can blow the cold air downward into the room, so that the lower space in the room is cooled faster, improving the user experience.

[0044] Specifically, the angle between the air inlet direction of the air inlet 101 and the air outlet direction of the air outlet 102 is 60°. In this way, the air conditioner sends cold air into the room through the air outlet duct. Since the angle between the air inlet direction of the air inlet 101 and the air outlet direction of the air outlet 102 is 60°, the air outlet 102 can blow cold air into the room in the direction of the lower part of the room, so that the lower part of the room is cooled faster, improving the user experience.

[0045] Optionally, the turning section 110 is an arc-shaped pipe structure. In this way, since the turning section 110 is an arc-shaped pipe structure, the bending transition is relatively gentle, which reduces the air volume loss during the process of the airflow passing through the turning section 110 and improves the performance of the air conditioner.

[0046] Combination Figure 2As shown, optionally, the air outlet duct 100 further includes: an air inlet section 120 and an air outlet section 130. The air inlet section 120 is connected to one end of the turning section 110, and the other end has an air inlet 101; one end of the air outlet section 130 is connected to the other end of the turning section 110, and the other end has an air outlet 102. In this way, the cold air in the air conditioner enters the air inlet section 120 from the air inlet 101, and then enters the turning section 110 from the air inlet section 120. The cold air flow is turned in the turning section 110, and is blown into the room from the air outlet section 130 and the air outlet 102.

[0047] Optionally, the flow rate of the air inlet 101 is greater than the flow rate of the air outlet 102. In this way, the flow rate of the air inlet 101 is greater than the flow rate of the air outlet 102. When the airflow passes through the air outlet 102 and blows into the room, the airflow at the air outlet 102 will be compressed because the air outlet 102 is relatively small, so that the temperature of the airflow is further reduced, thereby improving the cooling effect on the room.

[0048] Optionally, the guide plate 200 divides the turning section 110 into a first air cavity 111 and a second air cavity 112; wherein the first air cavity 111 has a first cavity inlet 113 and a first cavity outlet 114. Thus, when the airflow passes through the turning section 110, it will be divided into two airflows by the guide plate 200, one of which passes through the first air cavity 111 and the other passes through the second air cavity 112. Mutual disturbance between the airflow in the first air cavity 111 and the airflow in the second air cavity 112 is avoided, thereby reducing the air volume loss when the airflow direction changes, and improving the performance of the air conditioner.

[0049] Optionally, the flow rate of the first inlet cavity 113 is less than or equal to sixty-three percent of the flow rate of the air inlet section 120, and greater than or equal to forty-three percent of the flow rate of the air inlet section 120. In this way, when the flow rate of the first inlet cavity 113 is greater than sixty percent of the flow rate of the air inlet section 120, the flow rate of the first inlet cavity 113 is too large, and will occupy too much space in the second air cavity 112. When the flow rate of the first inlet cavity 113 is less than forty-three percent of the flow rate of the air inlet section 120, the flow rate of the first inlet cavity 113 is too small, so that the difference in air volume between the first air cavity 111 and the second air cavity 112 is too large, reducing the separation and guide effect of the guide plate 200. Therefore, it is more reasonable that the flow rate of the first inlet cavity 113 is less than or equal to sixty-three percent of the flow rate of the air inlet section 120, and greater than or equal to forty-three percent of the flow rate of the air inlet section 120, thereby reducing the difference in air flow between the first air cavity 111 and the second air cavity 112 and improving the separation and guide effects of the guide plate 200.

[0050] Specifically, the flow rate of the first inlet 113 is equal to 53% of the flow rate of the air inlet section 120. In this way, the difference in the air flow rate between the first air cavity 111 and the second air cavity 112 is reduced, and the separation and guide effects of the guide plate 200 are improved.

[0051] Optionally, the flow rate of the first cavity outlet 114 is less than or equal to fifty percent of the flow rate of the air inlet section 120, and greater than or equal to thirty percent of the flow rate of the air inlet section 120. In this way, when the flow rate of the first cavity outlet 114 is greater than fifty percent of the flow rate of the air inlet end, the space of the second air cavity 112 will be excessively occupied. When the flow rate of the first cavity outlet 114 is less than thirty percent of the flow rate of the air inlet section 120, the flow rate of the first cavity outlet 114 is too small, so that the airflow velocity of the first air cavity 111 is too slow. Therefore, the range in which the flow rate of the first cavity outlet 114 is less than or equal to fifty percent of the flow rate of the air inlet section 120, and greater than or equal to thirty percent of the flow rate of the air inlet section 120, is more reasonable, does not excessively occupy the space of the second air cavity 112, and the airflow velocity of the first air cavity 111 is also relatively high.

[0052] Specifically, the flow rate of the first outlet 114 is equal to 40% of the flow rate of the air inlet section 120. In this way, the space of the second air cavity 112 will not be excessively occupied, and the air flow rate of the first air cavity 111 is also relatively high.

[0053] Combination Figure 3 As shown, optionally, the deflector 200 has a windward end 210 and a leeward end 220, and the angle between the windward direction of the windward end 210 and the leeward direction of the leeward end 220 is a minor angle. In this way, corresponding to the minor angle between the air inlet direction of the air inlet 101 and the air outlet direction of the air outlet 102, and the bending direction of the deflector 200 is the same as that of the turning section 110, the deflector 200 can better separate the airflow in the turning section 110, reduce the air volume loss when the airflow direction changes, and improve the performance of the air conditioner.

[0054] Specifically, the angle between the windward direction of the windward end 210 and the leeward direction of the leeward end 220 is 85°.

[0055] Specifically, the angle between the windward direction of the windward end 210 and the leeward direction of the leeward end 220 is 55°.

[0056] Specifically, the distance between the windward end 210 and the air inlet end in the horizontal direction is greater than or equal to thirty-six percent of the diameter of the air inlet 101 , and less than or equal to fifty-six percent of the diameter of the air inlet 101 .

[0057] Specifically, the distance between the windward end 210 and the air inlet end in the horizontal direction is equal to forty-six percent of the diameter of the air inlet 101 .

[0058] Specifically, the length of the air outlet duct 100 in the horizontal direction is greater than or equal to ninety percent of the diameter of the air inlet 101 , and less than or equal to one hundred and ten percent of the diameter of the air inlet 101 .

[0059] Specifically, the length of the air outlet duct 100 in the horizontal direction is equal to the diameter of the air inlet 101 .

[0060] Combination Figure 4 and Figure 5 As shown, in some experimental examples, in order to more intuitively demonstrate the effect of the guide plate 200 in reducing the air volume loss caused by changing the air flow direction, the air outlet ducts 100 of the two experimental examples, Experimental Example 1: no guide plate 200 is set in the air outlet duct 100; and Experimental Example 2: the guide plate 200 is set in the air outlet duct 100, are simulated for flow fields.

[0061] Add 25Pa static pressure to the air inlet 101 of Experimental Example 1 and Experimental Example 2 respectively. Figure 4 and Figure 5 It can be seen that the lighter the color in the air outlet duct 100, the higher the static pressure, the greater the wind resistance, and the greater the air volume loss. The high static pressure area in the turning section 110 of Example 1 is significantly larger than the high static pressure area in the turning section 110 of Example 2, which means that the wind resistance of the turning section 110 of Experimental Example 1 is large, while the guide plate 200 in Experimental Example 2 reduces the wind resistance of the turning section 110, the air flow is smoother, and the air volume loss is smaller.

[0062] Optionally, a plurality of guide plates 200 are provided in the turning section 110. In this way, by providing a plurality of guide plates 200 in the turning section 110, and dividing and guiding the airflow in the turning section 110 through the plurality of guide plates 200, mutual interference between the airflows on both sides of each guide plate 200 is avoided, thereby reducing the air volume loss when the airflow direction changes, and improving the performance of the air conditioner. Moreover, the bending direction of each guide plate 200 is the same as the bending direction of the turning section 110, so that the flow direction of the airflow in the turning section 110 is consistent with the flow direction of the airflow guided by the guide plate 200, so that the flow of the airflow is smoother.

[0063] Specifically, two guide plates 200 are provided in the turning section 110. Thus, by providing two guide plates 200 in the turning section 110, and dividing and guiding the airflow in the turning section 110 through the two guide plates 200, mutual interference between the airflows on both sides of each guide plate 200 is avoided, thereby reducing the air volume loss when the airflow direction changes, and improving the performance of the air conditioner. Moreover, the bending direction of each guide plate 200 is the same as the bending direction of the turning section 110, reducing the resistance during the flow of the airflow, so that the flow direction of the airflow in the turning section 110 is consistent with the flow direction of the airflow guided by the guide plate 200, so that the flow of the airflow is smoother.

[0064] Combination Figure 6 As shown, optionally, the air conditioner further includes: a fixing plate 121. The fixing plate 121 is disposed in the air inlet section 120, and one end of the fixing plate 121 is fixedly connected to the windward end 210 of the guide plate 200. In this way, the airflow in the air inlet section 120 is pre-divided by the fixing plate 121, and the two divided airflows directly flow into the first air cavity 111 and the second air cavity 112.

[0065] Optionally, a plurality of fixing plates 121 are provided, and each fixing plate 121 is fixedly connected to the windward end 210 of a corresponding guide plate 200. In this way, the airflow in the air inlet section 210 is divided in advance by the fixing plates 121.

[0066] Specifically, two fixing plates 121 are provided.

[0067] Optionally, the guide plate 200 is an arc-shaped plate structure. In this way, the guide plate 200 of the arc-shaped plate structure has a relatively gentle bending transition, and the guide plate 200 provides guidance for the airflow in the turning section 110, reduces the air volume loss of the airflow in the process of passing through the turning section 110, and improves the performance of the air conditioner.

[0068] Optionally, the air conditioner further includes: an indoor unit 300. The air outlet duct 100 is disposed in the indoor unit 300. In this way, the air outlet duct 100 is disposed in the indoor unit 300, which reduces the risk of the air outlet duct 100 protruding from the outer surface of the indoor unit 300 and reduces the risk of the air outlet duct 100 colliding with other objects during the installation of the indoor unit 300. It can also reduce the heat exchange between the air outlet duct 100 and the outside world, and reduce the temperature loss of the air flow inside the air outlet duct 100.

[0069] Optionally, the air conditioner further includes: an air inlet duct 400. The air inlet duct 400 is arranged in the indoor unit 300, and the flow area of ​​the air inlet end of the air inlet duct 400 is larger than the flow area of ​​the air outlet end. In this way, the indoor air enters the indoor unit 300 through the air inlet duct 400, and is blown into the room through the air outlet duct 100 after heat exchange. Since the flow area of ​​the air inlet end of the air inlet duct 400 is larger than the flow area of ​​the air outlet end, the air inlet range of the air inlet end is relatively large, and air from more positions can be better sucked in.

[0070] Optionally, a guide plate 410 is provided at the air inlet end of the air inlet duct 400. In this way, the airflow is guided to flow into the air inlet duct 400 by providing the guide plate 410.

[0071] Combination Figure 7As shown, optionally, the guide plate 410 includes: a vertical plate 411 and an inclined plate 412. The upper end of the vertical plate 411 is fixedly connected to the lower end of the inclined plate 412. In this way, the airflow flows into the air inlet duct 400 through the vertical plate 411, and under the action of the inclined plate 412, the airflow changes its direction. In addition, due to the obstruction of the inclined plate 412, part of the dust in the air can be blocked, reducing the amount of dust sucked into the air inlet duct 400. When the air conditioner is powered off, the dust in the air inlet duct 400 falls down on the inclined plate 412 and slides down out of the air conditioner.

[0072] Optionally, the air inlet end of the air inlet duct 400 is provided with a plurality of vertical plates 411 and a plurality of inclined plates 412, and one inclined plate 412 is provided corresponding to each vertical plate 411. In this way, the airflow flows into the air inlet duct 400 through the plurality of vertical plates 411, and the airflow changes its direction under the action of the inclined plates 412. In addition, due to the obstruction of the inclined plates 412, part of the dust in the air can be blocked, reducing the amount of dust sucked into the air inlet duct 400. When the air conditioner is powered off, the dust in the air inlet duct 400 falls downward on the inclined plates 412, and slides downward to fall out from between the vertical plates 411.

[0073] Combination Figure 8 As shown, specifically, a heat exchange chamber 310 is provided inside the indoor unit 300, and both the air outlet duct 100 and the air inlet duct 400 are connected to the heat exchange chamber 310. In this way, the airflow enters the heat exchange chamber 310 from the air inlet duct 400 for heat exchange, and then is discharged from the air outlet duct 100.

[0074] Optionally, an evaporator 320 is provided in the heat exchange chamber 310, and the distance between the evaporator 320 and the air outlet duct 100 is greater than the distance between the evaporator 320 and the air inlet duct 400. In this way, the temperature of the airflow after heat exchange through the evaporator 320 is relatively low, and since the distance between the evaporator 320 and the air outlet duct 100 is relatively close, the airflow with a relatively low temperature can be quickly blown into the room, thereby improving the indoor cooling effect.

[0075] Optionally, the evaporator 320 is tiltedly arranged in the heat exchange chamber 310. In this way, the evaporator 320 is tiltedly arranged, so that the length of the evaporator 320 that can be arranged is relatively long, and the heat exchange area of ​​the evaporator 320 is increased, thereby improving the heat exchange effect.

[0076] Optionally, a fan 330 is provided in the heat exchange chamber 310, and the distance between the fan 330 and the air inlet duct 400 is greater than the distance between the fan 330 and the air outlet duct 100. In this way, when the fan 330 is running to suck in indoor air, since the distance between the fan 330 and the air inlet duct 400 is relatively small, the distance of sucking air is relatively short, thereby improving the effect of the fan 330 sucking air through the air inlet duct 400.

[0077] The above description and the accompanying drawings sufficiently illustrate the embodiments of the present disclosure to enable those skilled in the art to practice them.
