[0038] Figure 1 This is a schematic structural diagram of a guide plate guide structure according to an embodiment of the present invention, as shown in FIG. Figure 1 As shown, and reference Figures 2 to 7 An embodiment of the present invention provides a guide plate flow guiding structure 110 , which includes a guide plate body 111 and a plurality of flow guiding channels 113 .

[0039] like Figure 2-7 As shown, the guide plate body 111 is used to be installed at the front air outlet 151 of the air conditioner indoor unit 100. One side of the guide plate body 111 is an air guide surface 112, and the air guide surface 112 is an arc-shaped concave surface. The guide plate body 111 is at least configured to: Figure 7 As shown, when the guide plate body is in the first position, the air is guided toward the front and lower part of the air conditioner indoor unit 100; Figure 6 As shown, when the guide plate body is located at the second position, the front air outlet 151 of the air-conditioning indoor unit 100 is closed.

[0040] like Figure 1 As shown, the extension direction of the guide channel 113 is consistent with the bending direction of the arc-shaped concave surface, and a plurality of guide channels 113 are arranged on the wind guide surface 112 at intervals along the length direction of the guide plate body 111 .

[0041] Specifically, if Figure 5 and Figure 6 As shown, when the guide plate body 111 is in the second position, its side facing the interior of the housing 140 of the air conditioner indoor unit 100 serves as the air guide surface 112. The guide plate airflow guide structure 110 can be installed at the front air outlet 151 of a wall-mounted air conditioner indoor unit or a built-in air conditioner indoor unit. The built-in air conditioner indoor unit is a horizontally embedded structure. That is, the front air outlet 151 is elongated and extends along the length of the housing 140. The guide plate body 111 also extends along the length of the housing 140, meaning that the guide plate body 111 extends horizontally. The guide plate body 1111 is capable of switching between at least the first and second positions.

[0042] In this embodiment, by providing a curved air guide surface 112 and multiple air guide channels 113 disposed thereon, the air guide surface 112 and the air guide channels 113 serve a dual function of air guidance. When the guide plate body 111 is rotated to the first position, air can be directed forward and downward, that is, it simultaneously blows air forward and toward the area below the front air outlet 151. Compared to the prior art, this increases the air supply area and enhances the user experience. Therefore, the present invention solves the technical problem of the front air outlet 151 being unable to simultaneously deliver air downward while also delivering air forward.

[0043] like Figure 3 As shown, in some optional embodiments of the present invention, the guide channel 113 extends from one side edge to the other side edge of the wind guide surface 112 in the width direction, that is, the extension length of the guide channel 113 is consistent with the width direction of the wind guide surface 112.

[0044] In some alternative embodiments, the air guide channel 113 may also be provided only in the middle position of the air guide surface 112 in the width direction.

[0045] Compared with the structure in which the guide channel 113 is only arranged in the middle position of the air guide surface 112, the guide channel 113 extends from one side edge of the air guide surface 112 in the width direction to the other side edge, that is, the guide channel 113 runs through the air guide surface 112, which is more conducive to increasing the air supply distance, thereby being more conducive to uniform air flow indoors, and further improving the user experience.

[0046] In some optional embodiments of the present invention, a plurality of guide ribs are provided on the wind guide surface 112, and the plurality of guide ribs are arranged at intervals on the wind guide surface 112 along the length direction of the guide plate body 111. The extension direction of the guide ribs is consistent with the bending direction of the arc-shaped concave surface, and the gaps between adjacent guide ribs form a guide channel 113.

[0047] When the guide plate body 111 is in the second position or in another open position, air flows out from the front air outlet 151 and along the guide channel 113 between adjacent guide ribs on the air guide surface 112. The interaction between the guide channel 113 and the curved air guide surface not only changes the direction of the airflow, allowing the airflow to flow along the curved direction of the air guide surface, but also increases the air delivery distance.

[0048] In some optional embodiments of the present invention, the guide ribs extend from one edge to the other edge in the width direction of the wind guide surface 112. In other alternative embodiments, the guide ribs may be provided only in the middle of the width direction of the wind guide surface 112.

[0049] In some optional embodiments of the present invention, the guide ribs are integrally formed with the air guide surface. In some alternative embodiments, the guide ribs and the air guide surface are separate structures, and the guide ribs can also be bonded to the air guide surface.

[0050] In some optional embodiments of the present invention, the air guide surface 112 is provided with a plurality of guide grooves, which are arranged at intervals along the length of the guide plate body 111. The guide grooves extend in the same direction as the curvature of the arcuate concave surface, and the plurality of guide grooves form a plurality of guide channels 113. When the guide plate body 111 is in the second position or in another open position, air flowing out of the front air outlet 151 can flow along the guide grooves on the air guide surface 112.

[0051] Compared with the guide channel 113 structure formed by the guide grooves, the guide channel 113 structure formed by the guide ribs has the beneficial effect of being easy to manufacture and assemble.

[0052] like Figure 2 、 Figure 4 and Figure 5 As shown, in some optional embodiments of the present invention, the other side of the guide plate body 111 is a decorative surface 114, and the decorative surface 114 and the air guide surface 112 are located on both sides of the guide plate body 111. The decorative surface 114 is flat, and the thickness of the guide plate body 111 at both ends in the width direction is greater than the thickness in the middle.

[0053] When the front panel 141 of the air conditioning indoor unit 100 is flat, when the guide plate body 111 closes the front outlet, the flat decorative surface 114 can be flush with the front panel 141, thereby making the appearance of the air conditioning indoor unit 100 neat and beautiful.

[0054] In some optional embodiments of the present invention, the other side of the guide plate body 111 is a decorative surface, the decorative surface and the air guide surface are located on both sides of the guide plate body 111, and the decorative surface is an arc-shaped convex surface. The arc-shaped convex surface is adapted to the above-mentioned arc-shaped concave surface structure.

[0055] like Figure 1 and Figure 3 As shown, in some optional embodiments of the present invention, the guide plate air guide structure 110 further includes a rotating shaft 115, which is disposed at both ends of the guide plate body 111 in the longitudinal direction. The rotating shaft 115 is used to be mounted on the upper portion of the front air outlet 151 to drive the guide plate body 111 to rotate and adjust the rotation angle of the guide plate body 111. The rotating shaft 115 is disposed on the upper portion of the front air outlet 151 and is located at one end of the guide plate body 111 in the width direction. The guide plate body 111 can rotate with the rotating shaft 115 to open or close the front air outlet 151. The location of the rotating shaft 115 on the upper portion of the front air outlet 151 allows for a larger adjustment range of the air supply angle.

[0056] Furthermore, if Figure 1 and Figure 3 As shown, a connecting seat 116 is provided at each end of the wind guide surface 112. The connecting seat 116 has a mounting hole, and the rotating shaft 115 is installed in the connecting seat 116. A driving mechanism 160 is connected to the end of one rotating shaft for driving the rotating shaft to rotate. The driving mechanism 160 can be a motor.

[0057] like Figure 6 and Figure 7 As shown, the present invention further provides an air conditioning indoor unit 100, comprising a housing 140 and a guide plate flow guide structure 110. The housing 140 of the air conditioning indoor unit 100 is disposed horizontally. The housing 140 defines a front air outlet 151 that is open forward. The front air outlet 151 is elongated and extends along the length of the housing 140. The guide plate flow guide structure 110 is mounted at the front air outlet 151 and is the guide plate flow guide structure 110 described in any of the aforementioned embodiments.

[0058] In this embodiment, when the front air outlet 151 is open, the curved air guide surface 112 and the guide channel 113 cause the airflow to flow in an arc-shaped direction, thereby enabling the air conditioner indoor unit 100 to deliver air forward and downward. Compared with the prior art, this increases the air delivery area and improves the user experience. Therefore, the present invention solves the technical problem that the front air outlet 151 cannot deliver air downward while delivering air forward.

[0059] like Figure 6 and Figure 7 As shown, in some alternative embodiments of this embodiment, the air conditioner indoor unit 100 is a built-in air conditioner indoor unit 100. The advantages of a built-in air conditioner indoor unit 100 include saving indoor space, being aesthetically pleasing, and having low noise. Specifically, the built-in air conditioner indoor unit 100 can save indoor space, creating more spaciousness and reducing the need for bulky equipment and lines. The built-in air conditioner can be integrated with the wall or furniture, making the interior more aesthetically pleasing and neat. The built-in air conditioner indoor unit also operates with low noise, which can enhance the user experience. These advantages make it an ideal choice for modern homes and commercial spaces.

[0060] In some optional embodiments of the present invention, the air-conditioning indoor unit is a wall-mounted air-conditioning indoor unit. The wall-mounted air-conditioning indoor unit can be directly mounted on the wall, and the installation process is relatively simple. It only requires drilling a few holes in the wall and fixing the bracket to complete the installation. The wall-mounted air-conditioning indoor unit 100 can distribute cold air to the entire room more quickly, has high cooling efficiency, and can make the room temperature comfortable in a short time. The design of the wall-mounted air-conditioning indoor unit is beautiful and can be matched with interior decoration. It is not restricted by the installation location and can adapt to different home styles more flexibly. Therefore, the wall-mounted air conditioner not only meets the needs of modern families in terms of functionality, but also has significant advantages in installation, aesthetics, energy saving, etc., making it a preferred product in the modern family air-conditioning market.

[0061] like Figure 6 and Figure 7 As shown, in some optional embodiments of the present invention, the shell 140 is also formed with a front air inlet 152 open to the front, the front air inlet 152 is located above the front air outlet 151, and an air flow channel 153 connected between the front air inlet 152 and the front air outlet 151 is formed in the shell 140.

[0062] In this embodiment, the air flow duct adopts a front air flow and front air discharge structure, which is not restricted by the obstruction of the cabinet and can be more convenient for the installation and use of the embedded air conditioner indoor unit 100.

[0063] In some optional embodiments of the present invention, when the air conditioner indoor unit is a wall-mounted air conditioner indoor unit, the housing is further formed with an upper air inlet that opens upward. In other words, the air inlet can also be arranged on the upper side and / or front side of the housing.

[0064] like Figure 7 As shown, in some optional embodiments of the present invention, the housing 140 includes a front panel 141 and a rear shell 142, and the front panel 141 and the rear shell 142 are detachably connected together. The front air outlet 151 and the front air inlet 152 are both provided on the front panel 141.

[0065] Specifically, the front side of the rear housing 142 is open, and the front panel 141 is detachably connected to the front opening of the rear housing 142. The indoor heat exchanger 120, the water tray, and the fan 130 assembly are housed within the rear housing 142. When maintenance is required on the indoor heat exchanger 120, the fan 130, or the motor within the housing 140, the front panel 141 can be removed from the rear housing 142. These components can then be repaired or removed through the front opening of the rear housing 142, thereby improving component maintenance efficiency.

[0066] Furthermore, if Figure 3 As shown, a plug-in portion 1411 is provided at the bottom of the front panel 141 , and a slot portion is provided at the bottom of the rear shell 142 , and the plug-in portion 1411 is plugged and matched with the slot portion.

[0067] like Figure 6 and Figure 7 As shown, in some optional embodiments of the present invention, an indoor heat exchanger 120 and a fan 130 are provided within the airflow channel. The indoor heat exchanger 120 includes a first heat exchange portion 121 and a second heat exchange portion 122 connected in sequence along the front-to-back direction, with the first heat exchange portion 121 and the second heat exchange portion 122 being arranged at an angle. The fan 130 is disposed below the first heat exchange portion 121 and the second heat exchange portion 122. The indoor heat exchanger 120 is located between the front air inlet 152 and the front air outlet 151 and is configured to perform heat exchange on the airflow. The fan 130 is configured to facilitate the formation of an airflow that enters the air conditioner indoor unit 100 from the front air inlet 152 and is blown out from the front air outlet 151. The first heat exchange portion 121 is located in front of the second heat exchange portion 122. A gap is defined between the first heat exchange portion 121 and the third heat exchange portion 123 and the top of the airflow channel 153. Compared with an indoor heat exchanger 120 having only a flat plate structure, the first heat exchange portion 121 and the second heat exchange portion 122 of the indoor heat exchanger 120 in this embodiment are arranged at an angle, so that the indoor heat exchanger 120 has a larger heat exchange area.

[0068] In some optional embodiments of the present invention, the indoor heat exchanger 120 further includes a third heat exchange section 123, which is connected below the first heat exchange section 121 and is vertically arranged. The first heat exchange section 121 and the third heat exchange section 123 correspond to the front air outlet 151. The provision of the third heat exchange section 123 increases the heat exchange area of the indoor heat exchanger 120, thereby enhancing the heat exchange efficiency of the indoor heat exchanger 120.

[0069] like Figure 7 As shown, when the air conditioner indoor unit 100 is operating, air flows from the front air inlet 152 into the air flow channel 153 and is divided into two parts. One part of the air flows into the gap between the first heat exchange section 121, the third heat exchange section 123, and the front panel 141, and exchanges heat with the first and third heat exchange sections 121, 123. The other part of the air flows into the gap between the first and second heat exchange sections 121, 122 and the top of the air flow channel 153, and exchanges heat with the first and second heat exchange sections 121, 122.

[0070] like Figure 8 As shown, this embodiment further provides an air conditioner 10, which includes an air conditioner outdoor unit 200 and an air conditioner indoor unit 100 as described above.

[0071] At this point, those skilled in the art should recognize that, although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications consistent with the principles of the present invention can be directly determined or deduced from the contents disclosed herein without departing from the spirit and scope of the present invention.
