Therefore, this application is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0034] This application provides an indoor air conditioning unit to address the limitations of single-air-guide-plate air delivery methods. The following description, in conjunction with the accompanying drawings, will illustrate this approach.

[0035] In the embodiments of this application, such as Figure 1 and Figure 2 As shown, the indoor unit of the air conditioner includes:

[0036] The main body 1 has an air outlet duct 11.

[0037] Air guide 2, with both ends rotatably connected to the main body 1 along its length, the air guide 2 having a communicating air guide cavity 211 and a narrow air outlet 212, the air guide cavity 211 communicating with the air outlet channel 11; and,

[0038] The air guide plate 3 is rotatably connected to the air guide component 2. The rotation axis of the air guide plate 3 is set along its own length direction, and the air guide plate 3 rotates around the air guide component 2.

[0039] The air guide 2 is also provided with an air outlet 23, which is spaced apart on the lower side of the air guide cavity 211. The air guide plate 3 rotates to block or open the air outlet 23.

[0040] It should be noted that when the indoor unit of the air conditioner is in its normal installation position, the air guide plate 3 can be rotated to be located below the air guide component 2 to block the air outlet 23, or rotated to be located above the air guide component 2. The indoor unit of the air conditioner can be wall-mounted or floor-standing. The normal installation position of a wall-mounted air conditioner is when the length of the entire unit is aligned with or substantially aligned with the horizontal direction. The normal installation position of a floor-standing air conditioner is when the height of the entire unit is aligned with or substantially aligned with the direction of gravity. In this case, the two sides of the air guide plate 3 along its length direction are rotated horizontally and connected to the floor-standing air conditioner. In this embodiment, the maximum angle of rotation of the air guide plate 3 around the air guide component 2 can be 360 ​​degrees.

[0041] "The air outlet 23 is spaced below the air guide cavity 211" means that the air outlet 23 and the air guide cavity 211 are not directly connected. The airflow of the air outlet channel 11 flows to the air outlet 23 and the air guide cavity 211 respectively.

[0042] Understandably, in cooling mode, the rotatable air guide 2 is used to orient the narrow air outlet 212 towards the horizontal direction, and the air guide plate 3 is rotated to be positioned above the air guide 2. The air guide plate 3 is used to block the cold air from rising and guide the cold air to flow over a long distance, thus achieving the purpose of avoiding direct cold air blowing and delivering cold air over long distances. In heating mode, the narrow air outlet 212 of the air guide 2 is oriented towards the horizontal direction, and the air guide plate 3 is rotated to a near-vertical state to open the air outlet 23 and position the air guide plate 3 opposite to the air outlet channel 11. The near-vertical air guide plate 3 is used to obstruct the forward flow of hot air blown out of the air outlet channel 11 and guide the hot air to be concentrated and blown towards the ground. Compared with a single air guide plate 3 in related technologies, this can reduce wind loss and achieve floor-type hot air delivery.

[0043] Furthermore, based on the rotation method of the air guide plate 3 and the air guide component 2, users can make flexible adjustments to achieve different state combinations of the air guide plate 3 and the air guide component 2 to meet diverse air supply needs.

[0044] In some embodiments, such as Figure 2 and Figure 3As shown, the air guide 2 includes an air guide shell 21, which has an air guide cavity 211 and an air outlet narrow opening 212 along the air outlet direction. One end of the air guide cavity 211 is connected to the air outlet channel 11, and the other end of the air guide cavity 211 is connected to the air outlet narrow opening 212. The lower side wall of the air guide shell 21 and the side wall of the air outlet channel 11 enclose each other to form an air outlet opening 23.

[0045] It should be noted that "the lower sidewall of the air guide shell 21 and the sidewall of the air outlet channel 11 enclose to form an air outlet opening 23" means that at least one sidewall of the air guide shell 21 and the air outlet channel 11 are spaced apart. By rotating the air guide shell 21, the distance between it and the sidewall is changed, thereby changing the size of the air outlet opening 23. Furthermore, it is conceivable that when the air outlet opening 23 becomes smaller, the distance between the upper sidewall of the air guide shell 21 and the upper sidewall of the air outlet channel 11 becomes larger. It is conceivable that the air guide shell 21 is a hollow structure and has at least one opening connecting the air guide cavity 211 and the air outlet channel 11.

[0046] Understandably, the size of the air guide shell 21 allows it to rotate more flexibly within the air outlet channel 11, avoiding interference with other structures and increasing the range that the air outlet narrow opening 212 can sweep as it rotates with the air guide shell 21.

[0047] For example, in order to prevent the air guide plate 3 from interfering with the lower side wall of the air guide shell 21 when it moves from the position of blocking the air outlet 23 to opening the air outlet 23, the upper edge of the air guide plate 3 is spaced apart from the lower side wall of the air guide shell 21, and the air guide plate 3 is placed as close as possible to the side of the air guide shell 21 away from the cross-flow fan 4 of the indoor unit of the air conditioner.

[0048] In some embodiments, such as Figure 1 and Figure 2 As shown, the air guide 2 also includes two air guide side plates 22 respectively disposed on both sides of the air guide shell 21 along its length direction. The air guide shell 21 is rotatably disposed on the main body 1 through the air guide side plates 22.

[0049] It should be noted that the air guide shell 21 and the two air guide side plates 22 enclose each other to form an air guide cavity 211 with only one opening communicating with the air outlet channel 11. The lower side wall of the air guide shell 21, at least a portion of the two air guide side plates 22 and the side wall of the air outlet channel 11 enclose each other to form an air outlet opening 23.

[0050] It is understandable that the air guide side plate 22 is used to block the airflow from the air outlet channel 11 from overflowing from both sides, thereby reducing wind loss.

[0051] In some embodiments, such as Figure 4 and Figure 5As shown, the air guide side plate 22 rotates to fit against the side wall of the air outlet channel 11, the air guide 2 rotates to reduce or increase the air outlet opening 23, and at the same time increases or decreases the distance between the air guide shell 21 and the upper side wall of the air outlet channel 11.

[0052] It should be noted that "the air guide side plate 22 rotates to fit against the side wall of the air outlet duct 11" means that the outer edge of the air guide side plate 22 matches the side wall of the air outlet duct 11.

[0053] It is understandable that the main body 1 does not have a structure that obstructs the gap between the upper sidewall of the air outlet duct 11 and the upper sidewall of the air guide shell 21. When the air guide shell 21 rotates away from the sidewall of the air outlet duct 11, the airflow in the air outlet duct 11 can flow out from the air guide cavity 211 in the air guide shell 21 and from both sides of the air guide shell 21. At the same time, the air guide plate 3 is rotated to a suitable angle to adjust the airflow direction to the indoor area that needs air supply.

[0054] In some embodiments, such as Figure 2 and Figure 3 As shown, the air guide shell 21 is provided with at least one air guide surface 213, the air guide surface 213 has an air outlet narrow opening 212, and the air guide surface 213 is inclined outward about the air outlet narrow opening 212.

[0055] It should be noted that "the air guide surface 213 is inclined outward about the air outlet 212" means that the air guide surface 213 and the side wall of the air outlet 212 have an angle greater than 0 degrees and less than 180 degrees, and not equal to 90 degrees, and the air guide surface 213 gradually extends away from the air outlet 212. When there are multiple air guide surfaces 213, the multiple air guide surfaces 213 are arranged around the air outlet 212.

[0056] Understandably, based on the wall-attachment effect, the airflow will adhere to the air guide surface 213 after being blown out from the narrow air outlet 212 and then detach. The inclined air guide surface 213 guides the airflow direction and improves the air supply effect.

[0057] For example, two air guide surfaces 213 can be arranged opposite each other around the air outlet narrow opening 212. The two air guide surfaces 213 are arranged symmetrically about the air outlet narrow opening 212. In this way, the airflow can be guided to diffuse, and when air is delivered at a certain angle by the air guide shell 21, the discomfort caused by direct airflow can be reduced. Specifically, at least a portion of the air guide shell 21 can be inclined to form the air guide surface 213, so that at least a portion of the air guide shell 21 where the air outlet narrow opening 212 is located protrudes into the air guide cavity 211.

[0058] In some embodiments, the air guide shell 21 is provided with a clearance groove, and the air guide plate 3 is provided with a connecting arm, which passes through the clearance groove and is rotatably connected to the air guide shell 21.

[0059] It is understandable that the clearance groove is used to allow the connecting arm to move freely, thereby reducing the volume of the air guide 2. Of course, in other embodiments, the connecting arm can also be located on the outside of the air guide shell 21, for example, rotatably connected to the air guide side plate 22. Exemplarily, one or two connecting arms can be provided, depending on the air guide plate 3.

[0060] In addition, it should be noted that, in order to clearly show the positional relationship between the air guide plate 3 and the air guide component 2, the connecting arm is not shown in the figure.

[0061] In some embodiments, the connecting arm bends along the direction of the fan 4 of the indoor air conditioner towards the air guide plate 3, and the connecting arm is connected to the windward side of the air guide plate 3.

[0062] It should be noted that the fan 4 of the indoor unit of the air conditioner mainly refers to the cross-flow fan. The windward side of the air guide plate 3 refers to the side of the air guide plate 3 facing the cross-flow fan when the air guide plate 3 blocks the air outlet 23; and it is also defined that when the air guide plate 3 is rotated to other positions, it is also called the windward side.

[0063] It is understood that, through the connecting arm in this embodiment, when the air guide plate 3 rotates around the air guide member 2 to be located above the air guide member 2, the connecting arm avoids the air guide member 2, thus preventing interference between the air guide member 2 and the connecting arm, thereby affecting the rotation of the air guide plate 3. For example, the connecting arm is arc-shaped.

[0064] In some embodiments, such as Figure 4 As shown, the size of the end of the air guide cavity 211 that connects to the air outlet channel 11 is larger than the air outlet narrow opening 212.

[0065] It is understandable that as the airflow in the air outlet duct 11 flows out through the air guide cavity 211 and the air outlet narrow opening 212, the flow area becomes smaller, causing the flow velocity to increase. This results in the airflow flowing out of the air outlet narrow opening 212 flowing at high speed, accelerating the airflow around it, and guiding the airflow to flow over long distances.

[0066] In some embodiments, such as Figure 1 As shown, the air guide cavity 211 and the air outlet narrow opening 212 both extend along the length direction of the main body 1.

[0067] It is understandable that the lateral air outlet area of ​​the narrow air outlet 212 is increased to expand the air supply range.

[0068] In some embodiments, such as Figure 5 As shown, the wind guide plate 3 protrudes along its windward side towards the leeward side.

[0069] It should be noted that the windward side of the air guide plate 3 refers to the side of the air guide plate 3 facing the cross-flow fan 4 of the indoor air conditioning unit when the air guide plate 3 blocks the air outlet 23; and it is also defined as the windward side when the air guide plate 3 is rotated to other positions. The leeward side is the side of the air guide plate 3 away from the cross-flow fan 4 of the indoor air conditioning unit when the air guide plate 3 blocks the air outlet 23; and it is also defined as the leeward side when the air guide plate 3 is rotated to other positions.

[0070] It is understood that, according to the description of this embodiment, the air guide plate 3 is arc-shaped. In the cooling mode, the air guide plate 3 rotates to be located on the upper side of the air guide member 2. The air guide plate 3 with the above structure can guide the airflow to achieve long-distance, floor-type air delivery.

[0071] This application also provides an air conditioner, which includes the above-mentioned indoor unit and outdoor unit. The specific structure of the indoor unit is as described in the above embodiments. Since this air conditioner adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.
