[0039] like Figures 1 to 4 As shown, the wall-mounted air conditioner indoor unit according to the embodiment of the present invention may generally include a housing 10 , an upper air guide column 51 and a lower air guide column 52 .

[0040] The housing 10 defines a receiving space for receiving the main components of the air conditioner, and airflow for regulating the indoor environment is formed inside the housing 10, such as cold air in the cooling mode, hot air in the heating mode, and fresh air in the fresh air mode, etc. The housing 10 is provided with an air outlet 12 for blowing the airflow in the housing 10 toward the indoor environment.

[0041] The upper air guide column 51 includes a horizontal direction (all "horizontal" in this article refers to the same direction, which is the length direction of the housing 10, Figure 1 , Figure 2 The upper column 510 and at least one upper guide plate 531, 532 extending for guiding the wind are marked in the middle. The upper column 510 can be rotatably mounted on the air outlet 12 around the transverse axis x1, and each upper guide plate 531, 532 can be rotatably mounted on the outer peripheral surface of the upper air guide column 51 around the transverse axis x3, x4. The lower air guide column 52 is located lower than the upper air guide column 51, and includes a lower column 520 and at least one lower guide plate 541, 542, both of which extend transversely for guiding the wind.

Of course, the upper column 510, each upper guide plate 531, 532, the lower column 520, and each lower guide plate 541, 542 are equipped with respective motors (not shown) to drive them to rotate.

[0042] In the embodiment of the present invention, the upper column 510, the lower column 520, the upper guide plates 531, 532 and the lower guide plates 541, 542 can be rotated to have a variety of combination states, thereby obtaining a variety of air supply modes. Figure 3 As shown, the upper air guide column 51 and the lower air guide column 52 are placed in a forward blowing state to guide the air supply airflow forward. Figure 4 As shown, the upper air guide column 51 and the lower air guide column 52 are in a downward blowing state to guide the air supply airflow downward. This air guide structure is novel and ingenious, making the air conditioner product more distinctive, and subverting the appearance of the air conditioner, making the product higher in grade and providing a better user experience.

[0043] Specifically, in some embodiments, please refer to Figure 3 The upper column 510 can be made into a polygonal column as a whole, and the number of upper guide plates 531 and 532 is multiple, which are respectively connected to different sides of the upper column 510, so as to be rotated to a folded position close to the side of the upper column 510 or to an unfolded position parallel to the side of the upper column 510. Figure 3In the embodiment, the upper guide plate 531 is in the folded position, and the upper guide plate 532 is in the unfolded position. When the upper guide plates 531 and 532 are in the unfolded position, they can assist the upper column 510 in guiding the wind. The side of the upper column 510 can be provided with a receiving groove 505 for receiving the upper guide plates 531 and 532, so as to receive the upper guide plates 531 and 532 when the upper guide plates 531 and 532 are in the folded position.

[0044] The lower column 520 is in the shape of a polygonal column as a whole, and there are multiple lower guide plates 541 and 542, which are respectively connected to different sides of the lower column 520, so as to be rotated to a folded position close to the side of the lower column 520 or to an unfolded position parallel to the side of the lower column 520. Figure 3 In the embodiment, the lower guide plate 542 is in the folded position, and the lower guide plate 541 is in the unfolded position. When the lower guide plates 541 and 542 are in the unfolded position, they can assist the lower column 520 in guiding the wind. The side of the lower column 520 can be provided with a receiving groove 506 for receiving the upper guide plates 531 and 532, so as to receive the lower guide plates 541 and 542 when the lower guide plates 541 and 542 are in the folded position.

[0045] Please refer to Figure 3 The upper cylinder 510 is configured to rotate around a first hinge edge T1 among its multiple edges, and the lower cylinder 520 is configured to rotate around a second hinge edge T2 among its multiple edges.

[0046] Specifically, the upper column 510 is in the shape of a triangular prism as a whole, and its three side surfaces include two first wind guide surfaces 511, 512 and a first wind shielding surface 513, and the two first wind guide surfaces 511, 512 intersect at the first hinge edge T1. There are two upper guide plates 531, 532, and they are rotatably connected to the two edges of the upper column 510 except the first hinge edge T1. The lower column 520 is in the shape of a triangular prism as a whole, and its three side surfaces include two second wind guide surfaces 521, 522 and a second wind shielding surface 523, and the two second wind guide surfaces 521, 522 intersect at the second hinge edge T2. There are two lower guide plates 541, 542, and they are rotatably connected to the two edges of the lower column 520 except the second hinge edge T2.

[0047] Of course, in the embodiment of the present invention, the function of the upper column 510 and the lower column 520 is to guide the wind, and they do not need to be designed as an absolute triangular prism in the mathematical sense, but can also be roughly triangular prism-shaped, for example, some or all of their side surfaces are convex or concave curved surfaces (such as arc surfaces), or irregular curved surfaces, and their two end surfaces can also be curved surfaces. In addition, the transition between two adjacent side surfaces can also be rounded. In short, the upper column 510 and the lower column 520 can each have three side surfaces facing different directions to facilitate wind guidance.

[0048] like Figure 3 As shown, the housing 10 may define an air duct 15 connected to the air outlet 12, and the air duct 15 may have a front air duct wall 151 and a rear air duct wall 152 arranged in front and back. The air duct 15 may be a crossflow air duct for matching a crossflow fan, the front air duct wall 151 being a volute tongue, and the rear air duct wall 152 being a volute. The first hinge edge T1 and the second hinge edge T2 are respectively close to the front air duct wall 151 and the rear air duct wall 152.

[0049] like Figure 3 As shown, the upper wind guide column 51 and the lower wind guide column 52 are configured to have a front wind guiding state in which the first wind shielding surface 513 faces the inner side of the wind duct 15, an upper guide plate 532 is deployed forward, a second wind guide surface 521 faces upward, and a lower guide plate 541 adjacent to the second wind guide surface 521 is deployed forward, so that a forward wind guiding channel is formed between the upper guide plate 532, the lower guide plate 541 and the second wind guide surface 521.

[0050] like Figure 4 As shown, the upper air guide column 51 and the lower air guide column 52 are configured to have a lower air guide state in which a first air guide surface 511 faces backward, an upper guide plate 531 adjacent to the first air guide surface 511 is unfolded downward, a second air guide surface 521 faces forward, and an adjacent lower guide plate 541 is unfolded downward. The second hinge edge T2 can be located at the rear edge of the air outlet 12 to facilitate guiding the airflow forward and downward.

[0051] When the wall-mounted air conditioner indoor unit operates in cooling mode, the upper air guide column 51 and the lower air guide column 52 can be adjusted to the aforementioned front air guide state to guide the cold air flow forward or forward over a long distance. When the wall-mounted air conditioner indoor unit operates in heating mode, the upper air guide column 51 and the lower air guide column 52 can be adjusted to the aforementioned lower air guide state to guide the hot air flow toward the ground.

[0052] Figure 5 yes Figure 3 The wall-mounted air conditioner indoor unit is a schematic diagram when the upper air guide column 51 and the lower air guide column 52 are in a closed state.

[0053] like Figure 5 As shown, the upper air guide column 51 and the lower air guide column 52 are also configured to have a closed state in which the first wind shielding surface 513 and the second wind shielding surface 523 are opposite to each other to close the air duct 15. When the wall-mounted air conditioner indoor unit is in the shutdown state, the upper air guide column 51 and the lower air guide column 52 can be rotated to the closed state.

[0054] Figure 6 yes Figure 3 The wall-mounted air conditioner indoor unit is a schematic diagram when the upper air guide column 51 and the lower air guide column 52 are in a breeze state.

[0055] like Figure 6As shown, the upper wind guide column 51 and the lower wind guide column 52 can be further configured to have a state in which the first wind shield surface 513 faces the inner side of the air duct 15, an upper guide plate 532 is unfolded forward, the second wind shield surface 523 faces upward, and the lower guide plate 542 is unfolded forward, so as to form a ventilation gap between the upper wind guide column 51 and the lower wind guide column 52, so that the airflow is blown out with a small amount of air to form a breeze effect.

[0056] Of course, it is understandable that Figures 3 to 6 It is only a partial illustration of the preferred air supply modes of the embodiment of the present invention. In addition, those skilled in the art can also obtain more air supply modes by combining and matching the angles of the upper air guide column 51 and the lower air guide column 52, which will not be described one by one here.

[0057] like Figure 3 As shown, the indoor unit of the wall-mounted air conditioner can use a vapor compression refrigeration cycle system for cooling / heating. An indoor heat exchanger 30 and a fan 40 are provided inside the housing 10. The indoor heat exchanger 30 and the throttling device are connected to the compressor, the outdoor heat exchanger and other refrigeration elements arranged in the outdoor unit of the air conditioner through pipelines to form a vapor compression refrigeration cycle system. Under the action of the fan 40, the indoor air enters the interior of the housing 10 through the air inlet 11 at the top of the housing 10, and after completing the forced convection heat exchange with the indoor heat exchanger 30, a heat exchange wind is formed, and then blown to the indoor environment through the air outlet 12 under the guidance of the air duct 15 to complete the adjustment of the indoor environment air. The fan 40 is preferably a cross-flow fan, which is arranged at the inlet of the air duct 15. The indoor heat exchanger 30 is preferably a three-stage heat exchanger.

[0058] 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 that conform to the principles of the present invention can still be directly determined or derived based on the content disclosed in the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all these other variations or modifications.
