[0046] Exemplary embodiments of the present utility model will be described herein below with reference to the accompanying drawings. While exemplary embodiments of the present utility model are shown in the drawings, it is understood that the present utility model can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the present utility model to those skilled in the art.

[0047] As shown in Figure 1 and Figure 2 , the air conditioner indoor unit 10 of the present utility model embodiment can generally include a housing 100. Specifically, a front side middle portion of the housing 100 is provided with an air outlet 150 open forward. Thus, the air outlet direction of the air conditioner indoor unit 10 of the present utility model is forward air outlet.

[0048] As shown in Figures 3-14 , the air conditioner indoor unit 10 of the present utility model embodiment can further include at least one axial fan 200. Specifically, the axial fan 200 is arranged in the housing 100, for promoting the airflow in the housing 100 to blow out through the air outlet 150. That is, the air conditioner indoor unit 10 of the present utility model embodiment is provided with the axial fan 200 upstream of the air outlet 150, for promoting the airflow in the housing 100 to flow forward and blow out through the air outlet 150.

[0049] As Figures 1-4 and Figures 6-14 indicated, the air conditioner indoor unit 10 of the embodiment of the present application can further include a plurality of air deflectors (not shown in the figure). The plurality of air deflectors are rotatably arranged in the air outlet 150 and have a scattering position for guiding the airflow in the casing 100 to diffuse forwardly out of the air outlet 150, a converging position for guiding the airflow in the casing 100 to converge forwardly out of the air outlet 150, an up-blowing position for guiding the airflow in the casing 100 to tilt forwardly and upwardly out of the air outlet 150, and a down-blowing position for guiding the airflow in the casing 100 to tilt forwardly and downwardly out of the air outlet 150. That is, when the plurality of air deflectors are in different positions, the air conditioner indoor unit 10 of the embodiment of the present application can realize different axial flow air supply forms. Further, each air deflector can be controlled to rotate respectively, so that the plurality of air deflectors can be switched between the scattering position, the converging position, the up-blowing position and the down-blowing position. Thus, the air conditioner indoor unit 10 of the embodiment of the present application realizes multi-form axial flow air supply by switching the positions of the plurality of air deflectors.

[0050] In addition, the plurality of air deflectors also have a closing position in which each air deflector extends vertically to completely close the air outlet 150. Correspondingly, each air deflector can also be controlled to rotate respectively, so that the plurality of air deflectors can be switched between the scattering position, the converging position, the up-blowing position, the down-blowing position and the closing position.

[0051] Thus, the air conditioner indoor unit 10 of the embodiment of the present application, including the casing 100, at least one axial flow fan 200 and a plurality of air deflectors, realizes axial flow air supply with air blowing forwardly by opening the air outlet 150 which opens forwardly in the middle of the front side of the casing 100, and arranging the axial flow fan 200 in the casing 100 to cause the airflow in the casing 100 to blow out through the air outlet 150. In addition, the plurality of air deflectors are rotatably arranged in the air outlet 150 and have the scattering position, the converging position, the up-blowing position, the down-blowing position and the closing position, and each air deflector can be controlled to rotate respectively, so that the plurality of air deflectors can be switched between the scattering position, the converging position, the up-blowing position, the down-blowing position and the closing position, realizing switching of the multi-form axial flow air supply of the forwardly diffusing, the forwardly converging, the up-blowing and the down-blowing, thereby avoiding the problem of single air supply form, and further improving the heat exchange effect of the air conditioner indoor unit 10, thereby improving the user's use experience.

[0052] In one specific embodiment, as Figures 1-4 and Figures 6-14As shown, the number of air deflector in the air conditioner indoor unit 10 of the embodiments of the present application can be two, that is, the air conditioner indoor unit 10 can include an upper air deflector 500 and a lower air deflector 600. The upper air deflector 500 and the lower air deflector 600 are rotatably arranged in the air outlet 150 and have a closed position in which they extend vertically to completely close the air outlet 150, a diffusion position for guiding the airflow in the housing 100 to diffuse and blow out from the air outlet 150, a convergence position for guiding the airflow in the housing 100 to converge and blow out from the air outlet 150, an upper blowing position for guiding the airflow in the housing 100 to tilt and blow out from the air outlet 150, and a lower blowing position for guiding the airflow in the housing 100 to tilt and blow out from the air outlet 150.

[0053] When the upper air deflector 500 and the lower air deflector 600 are in different positions, the air conditioner indoor unit 10 of the embodiments of the present application can realize different axial flow air supply forms. Further, the upper air deflector 500 and the lower air deflector 600 can be controlled to rotate respectively to switch the closed position, the diffusion position, the convergence position, the upper blowing position and the lower blowing position. Thus, the air conditioner indoor unit 10 of the embodiments of the present application realizes multi-form axial flow air supply by switching the positions of multiple air deflectors.

[0054] In some embodiments, as shown in Figure 1 and Figure 2 , the housing 100 of the air conditioner indoor unit 10 of the embodiments of the present application extends horizontally in a column shape. In addition, as shown in Figure 1 , the air outlet 150 is located in the vertical middle part of the front side of the housing 100 and extends horizontally in a strip shape. That is, the size of the housing 100 of the air conditioner indoor unit 10 in the left-right direction is greater than the size of the housing 100 in the up-down direction, and the size of the air outlet 150 in the left-right direction of the housing 100 is greater than the size of the air outlet 150 in the up-down direction of the housing 100.

[0055] Thus, the air conditioner indoor unit 10 of the embodiments of the present application, by opening the horizontally extending and strip-shaped air outlet 150 in the vertical middle part of the front side of the horizontally extending housing 100, realizes the shape matching of the air outlet 150 and the housing 100, improves the appearance uniformity and aesthetic degree of the front panel 130. At the same time, the air outlet 150 is arranged in the vertical middle part of the front side of the housing 100, realizing the middle part air outlet, compared with the traditional front and downward air outlet scheme, improving the adjustability of the air supply angle and the maximum air supply distance, helping the heat exchange airflow to reach a farther area to more evenly cover the room, thereby improving the distribution uniformity of the heat exchange airflow in the room, and further improving the heat exchange uniformity of the air conditioner indoor unit 10.

[0056] In some embodiments, as shown in Figures 1-3 and Figures 6-14As shown, multiple air deflectors are vertically spaced in the air outlet 150, and each air deflector is a horizontally extending strip-shaped flat plate and can rotate around a horizontal axis to facilitate adjusting the air outlet direction of the air outlet 150 in the vertical direction. That is, each air deflector is a horizontally extending strip-shaped flat plate, and multiple air deflectors are arranged in the air outlet 150 in the up-down direction of the shell. In one specific embodiment, as shown in Figures 6-14 each air deflector is parallel to the left-right direction of the air outlet 150 in the length direction. In addition, the rotation axis of each air deflector is parallel to the length direction and located in the middle of the width direction.

[0057] Therefore, in the air conditioner indoor unit 10 of the embodiment of the present application, the horizontally extending strip-shaped air deflector is unified with the design style of the horizontally extending columnar shell 100, which ensures the appearance of the air conditioner indoor unit 10. In addition, the air conditioner indoor unit 10 of the embodiment of the present application realizes precise control of the air outlet direction of the air conditioner indoor unit 10 in the vertical direction by arranging multiple independently adjustable air deflectors. At the same time, the multiple horizontally extending strip-shaped air deflectors rotating around the horizontal axis realize adjustment of the air outlet direction in the vertical direction, maximize the adjustment of the air supply range in the left-right direction of the shell 100, optimize the distribution uniformity of the heat exchange airflow, improve the comfort and energy efficiency, and also consider the appearance and practicality, which is particularly suitable for scenes requiring zoned air supply, large space or high floor height. By opening the horizontally extending and strip-shaped air outlet 150 in the vertical middle part of the front side of the horizontally extending shell 100, the air outlet 150 is matched with the shape of the shell 100, which improves the appearance uniformity and appearance of the front panel 130. At the same time, the air outlet 150 is arranged in the vertical middle part of the front side of the shell 100, which realizes the air outlet from the middle part to the front. Compared with the traditional air outlet from the front to the bottom, the air supply angle is adjustable and the maximum air supply distance is improved, which helps the heat exchange airflow to reach a farther area to cover the room more uniformly, thereby improving the distribution uniformity of the heat exchange airflow in the room, and further improving the heat exchange uniformity of the air conditioner indoor unit 10.

[0058] Further, as shown in Figure 7 or Figure 10 when the multiple air deflectors are in the air diffusion position, the distance between the adjacent two air deflectors gradually increases from back to front. As shown in Figure 6 or Figure 11 when the multiple air deflectors are in the air diffusion position, the distance between the adjacent two air deflectors gradually decreases from back to front. As shown in Figure 8 or Figure 12 when the multiple air deflectors are in the air diffusion position, each air deflector is inclined upward from back to front. As shown in Figure 9 or Figure 13As shown, when the plurality of air deflectors are in the down-blowing position, each air deflector is inclined downward from back to front. In addition, as shown Figure 2 or Figure 14 As shown, when the plurality of air deflectors are in the closed position, each air deflector is vertically extended.

[0059] In one specific embodiment, as shown Figures 1-4 and Figures 6-14 The number of air deflectors in the air conditioner indoor unit 10 can be two, i.e. the air conditioner indoor unit 10 can include an upper air deflector 500 and a lower air deflector 600. In this embodiment, the upper air deflector 500 and the lower air deflector 600 are vertically spaced apart in the air outlet 150, and the upper air deflector 500 and the lower air deflector 600 are both horizontally extended strip-shaped flat plates and can rotate around a horizontal axis to facilitate adjustment of the air outlet direction of the air outlet 150 in the vertical direction.

[0060] Specifically, as shown Figure 7 or Figure 10 As shown, when the upper air deflector 500 and the lower air deflector 600 are in the down-blowing position, the distance between the upper air deflector 500 and the lower air deflector 600 gradually increases from back to front. Thus, in the airflow direction, the airflow flows forward and diffuses, and is blown out in a large range, to achieve the down-blowing air supply form of the air conditioner indoor unit 10.

[0061] As shown Figure 6 or Figure 11 As shown, when the upper air deflector 500 and the lower air deflector 600 are in the down-blowing position, the distance between the upper air deflector 500 and the lower air deflector 600 gradually increases from back to front. Thus, in the airflow direction, the airflow flows forward and diffuses, and is blown out in a large range, to achieve the down-blowing air supply form of the air conditioner indoor unit 10.

[0062] As shown Figure 8 or Figure 12 As shown, when the upper air deflector 500 and the lower air deflector 600 are in the down-blowing position, the distance between the upper air deflector 500 and the lower air deflector 600 gradually increases from back to front. Thus, in the airflow direction, the airflow flows forward and diffuses, and is blown out in a large range, to achieve the down-blowing air supply form of the air conditioner indoor unit 10.

[0063] As shown Figure 9 or Figure 13 As shown, when the upper air deflector 500 and the lower air deflector 600 are in the down-blowing position, the distance between the upper air deflector 500 and the lower air deflector 600 gradually increases from back to front. Thus, in the airflow direction, the airflow flows forward and diffuses, and is blown out in a large range, to achieve the down-blowing air supply form of the air conditioner indoor unit 10.

[0064] In addition, as shown Figure 2 or Figure 14As shown, the upper air deflector 500 and the lower air deflector 600 are both vertically extended when the upper air deflector 500 and the lower air deflector 600 are in the closed position. Thus, the air outlet 150 is completely closed, so that the front side appearance of the air conditioner indoor unit 10 has continuity, so as to improve the overall aesthetic level of the air conditioner indoor unit 10.

[0065] Thus, in the air conditioner indoor unit 10 of the embodiment of the present application, the upper air deflector 500 and the lower air deflector 600 have a scattering position, a converging position, an upper blowing position, a lower blowing position and a closed position, and can be switched between the multiple air supply positions, realizing the switching of multiple air supply forms of forward diffusion, forward convergence, upper blowing and lower blowing, thereby realizing multiple axial air supply, avoiding the problem of single air supply form, and further improving the heat exchange effect of the air conditioner indoor unit 10, thereby improving the user's use experience.

[0066] In some embodiments, as shown in Figures 3-5 The air conditioner indoor unit 10 can include multiple axial flow fans 200. The multiple axial flow fans 200 are arranged in the left-right direction of the shell 100, so that the air flow in the shell 100 is blown forward under the urging of the multiple axial flow fans 200.

[0067] Further, as shown in Figure 4 The central axes of the multiple axial flow fans 200 are parallel. Specifically, the central axis of each axial flow fan 200 extends horizontally and is arranged parallel to the front-rear direction of the shell 100.

[0068] Thus, the multiple axial flow fans 200 arranged in the left-right direction can operate simultaneously, improving the left-right uniformity and air supply amount of the air conditioner indoor unit 10 while realizing left-right synchronous forward air supply, thereby increasing the overall air supply amount and heat exchange effect of the air conditioner indoor unit 10.

[0069] In one specific embodiment, as shown in Figure 5 The rotation direction of each axial flow fan 200 is opposite to the rotation direction of the axial flow fan 200 adjacent thereto, so as to converge the air flow blown by the multiple axial flow fans 200 in front of the shell 100.

[0070] Thus, when the plurality of axial flow fans 200 rotate in opposite directions, the airflow generated by each two adjacent axial flow fans 200 forms a certain interaction and superposition inside the air conditioner indoor unit 10, which enhances the disturbance and mixing of the airflow, thereby improving the airflow circulation efficiency and uniformity inside the air conditioner indoor unit 10. In addition, the reverse rotation of each two adjacent axial flow fans 200 can reduce the collision and offset of the airflow when meeting, which not only reduces the overall noise level of the air conditioner indoor unit 10 during operation, but also improves the air supply distance of each axial flow fan 200, thereby facilitating the convergence of the airflow blown by the plurality of axial flow fans 200 in front of the shell 100, and further improving the air supply effect of the air conditioner indoor unit 10.

[0071] In some embodiments, as shown in FIGS. 1 and 2, the number of axial flow fans 200 in the air conditioner indoor unit 10 of the present application is two. Specifically, the two axial flow fans 200 are symmetrically arranged in the left-right direction of the shell 100, and the central axes of the two axial flow fans 200 are parallel. Figures 3-5

[0072] Thus, the airflow of the two axial flow fans 200 converges to the central position in front of the shell 100. In addition, the rotation directions of the two axial flow fans 200 are opposite, so as to facilitate the convergence of the airflow blown by the plurality of axial flow fans 200 in front of the shell 100, thereby improving the air supply effect of the air conditioner indoor unit 10.

[0073] In some embodiments, as shown in FIGS. 1 and 2, the number of axial flow fans 200 in the air conditioner indoor unit 10 of the present application is two. Specifically, the two axial flow fans 200 are symmetrically arranged in the left-right direction of the shell 100, and the central axes of the two axial flow fans 200 are parallel. Figure 3 Figure 4 Figures 6-14 As shown in FIGS. 1 and 2, the air conditioner indoor unit 10 can further include a heat exchanger 300. Specifically, the heat exchanger 300 is arranged in the shell 100 and located between the axial flow fan 200 and the air outlet 150, and is used for heat exchange with the airflow blown by the axial flow fan 200. That is, the heat exchanger 300 is arranged between the axial flow fan 200 and the air outlet 150. Thus, the airflow entering the shell 100 from the air inlet 140 can be fully contacted with the heat exchanger 300 under the driving action of the axial flow fan 200 and then blown out through the air outlet 150.

[0074] Thus, while achieving the inclined downward air outlet, the air conditioner indoor unit 10 of the present application avoids the problems of insufficient contact of the inlet airflow with the heat exchanger 300, uneven heat exchange, and high noise caused by directly arranging the axial flow fan 200 at the air outlet 150, ensures that the airflow in the air conditioner indoor unit 10 has fully entered the internal space of the air conditioner indoor unit 10 before being driven by the axial flow fan 200 to pass through the heat exchanger 300, improves the contact time and uniformity of the airflow with the heat exchanger 300, thereby improving the heat exchange efficiency of the air conditioner indoor unit 10, and further improving the heat exchange effect of the air conditioner indoor unit 10.

[0075] ​​​In some embodiments, as shown in Figure 3 、 Figure 4 、 Figures 6-14 , the heat exchanger 300 is in the form of a flat plate extending vertically, and the size of the heat exchanger 300 in the up-down direction of the shell 100 is greater than the size of the axial flow fan 200 in the up-down direction of the shell 100. In addition, the side of the heat exchanger 300 away from the axial flow fan 200 and the shell 100 define an air outlet space 310. That is, the heat exchanger 300 can be designed as a straight type and vertically arranged in the shell to save the overall thickness space of the air conditioner indoor unit 10.

[0076] Further, as shown in Figures 6-14 , in the air conditioner indoor unit 10 of the present application, the heat exchanger 300 is arranged perpendicular to the central axis of the axial flow fan 200. Thus, the posture of the heat exchanger 300 is matched with the posture of the plurality of axial flow fans 200, so as to facilitate the closer arrangement of the heat exchanger 300 and the plurality of axial flow fans 200, and reduce the distance between the airflow blown by each axial flow fan 200 and the heat exchanger 300, thereby improving the uniformity of the air speed of the air conditioner indoor unit 10, and further improving the heat exchange efficiency of the air conditioner indoor unit 10. At the same time, the heat exchanger 300 is vertically arranged in the shell, reducing the occupied space of the heat exchanger 300 in the air conditioner indoor unit 10, and further optimizing the space layout in the air conditioner indoor unit 10.

[0077] In some embodiments, as shown in Figures 3-14 , the air conditioner indoor unit 10 can further include a fan cover 400. The fan cover 400 is arranged in the shell 100 between the axial flow fan 200 and the heat exchanger 300, and is used to guide the airflow blown by the axial flow fan 200 to flow towards the heat exchanger 300. That is, the fan cover 400 is fixedly arranged at the air outlet end of the axial flow fan 200, and guides the airflow blown by the axial flow fan 200 to flow towards the side surface of the heat exchanger 300.

[0078] Thus, in the air conditioner indoor unit 10 of the present application, the fan cover 400 can ensure that the airflow blown by the axial flow fan 200 directly and orderly flows to the heat exchanger 300, reducing the turbulence and energy loss of the airflow. At the same time, the directional airflow flow helps to enhance the convective heat transfer coefficient of the surface of the heat exchanger 300, thereby improving the overall heat exchange efficiency of the air conditioner indoor unit 10. In addition, the airflow in the air conditioner indoor unit 10 is more uniformly distributed on the surface of the heat exchanger 300 through the guidance of the fan cover 400, avoiding the phenomenon of local overheating or overcooling.

[0079] In some embodiments, as shown in Figure 4As shown, the fan cover 400 and the heat exchanger 300 define a plurality of separately arranged air outlet cavities 411. The plurality of air outlet cavities 411 are arranged one-to-one with the plurality of axial flow fans 200, so that the air flow blown by the plurality of axial flow fans 200 respectively flows to the heat exchanger 300.

[0080] Specifically, the fan cover 400 can include a baffle plate 410 extending vertically and in a flat plate shape, a plurality of annular fan mounting portions 420 protruding rearward from the vertical middle portion of the baffle plate 410 and arranged in the left-right direction, and a strip-shaped partition plate 430 located between two adjacent fan mounting portions 420 and protruding forward from the front side of the baffle plate 410.

[0081] In the present embodiment, the fan mounting portion 420 is used to mount and fix the axial flow fan 200, so that the baffle plate 410 covers the outer circumferential side of the air outlet end of the axial flow fan 200. Thus, the baffle plate 410, the partition plate 430 located between two adjacent axial flow fans 200, the heat exchanger 300, and the shell 100 can collectively define a plurality of air outlet cavities 411 corresponding to each axial flow fan 200, so that each axial flow fan 200 corresponds to an independent air outlet cavity 411.

[0082] For example, as shown in Figs. 1 and 2, Figure 4 The air conditioner indoor unit 10 can include two axial flow fans 200. Accordingly, the fan cover 400 can include a baffle plate 410, two fan mounting portions 420 arranged symmetrically in the left-right direction of the baffle plate 410, and a strip-shaped partition plate 430 located in the transverse middle portion of the baffle plate 410, to define two air outlet cavities 411 corresponding to the two axial flow fans 200 with the heat exchanger 300, so that the air flow blown by the two axial flow fans 200 respectively flows to the heat exchanger 300.

[0083] Thus, in the air conditioner indoor unit 10 of the present embodiment, each axial flow fan 200 corresponds to an independent air outlet cavity 411, thereby ensuring that the air flow generated by each axial flow fan 200 can be effectively guided to the heat exchanger 300 without mutual interference or mixing. The distribution of air flow on the surface of the heat exchanger 300 is more uniform and orderly, thereby improving the heat exchange efficiency.

[0084] In some embodiments, as shown in Figs. 1 and 2, Figures 1-4 , Figure 6 and Figure 7 The shell 100 includes a rear cover 110, an air outlet frame 120, and a front panel 130 arranged in sequence in the front-rear direction.

[0085] Specifically, the rear cover 110 is provided with an air inlet 140, and the air outlet 150 is arranged at the vertical and horizontal middle part of the front panel 130. In addition, the rear cover 110, the air outlet frame 120 and the front panel 130 are sequentially connected and fixed in the front-rear direction of the shell 100, and the air outlet frame 120 is inwardly provided with a mounting piece 121 for mounting and fixing the heat exchanger 300, so that the heat exchanger 300 is arranged in the air outlet frame 120. Therefore, the air conditioner indoor unit 10 of the embodiment has a rear air inlet and a front air outlet.

[0086] In one embodiment, as shown in Figures 2-4 、 Figure 6 and Figure 7 , the air inlet 140 includes a plurality of air inlet holes 141 arranged at intervals on the outer circumferential side of the rear cover 110, so that the airflow can enter the shell 100 from various directions at the rear of the shell 100.

[0087] Specifically, the plurality of air inlets 140 are uniformly arranged at intervals on the outer circumferential side of the rear cover 110, so as to improve the uniformity of the airflow entering the shell 100, and reduce the vortex and turbulence of the airflow inside the shell 100, thereby improving the stability and efficiency of the airflow.

[0088] Therefore, the air conditioner indoor unit 10 of the embodiment has a rear air inlet and a front air outlet.

[0089] In one embodiment, as shown in Figure 1 、 Figures 6-9 , the front panel 130 is a bent panel vertically extending at the vertical middle part, and the upper and lower sides of the vertical middle part extend backward at an angle, and the horizontal middle part of the vertical middle part of the front panel 130 is open to form the air outlet 150, so that the airflow at the air outlet 150 has a tendency to blow horizontally forward.

[0090] In this alternative embodiment, when the plurality of air deflectors are in the air diffusion position, the airflow at the air outlet diffuses horizontally forward and blows widely, so as to realize the air diffusion blowing form of air diffusion. In addition, when the plurality of air deflectors are in the air convergence position, the airflow at the air outlet converges forward and blows at high speed, so as to realize the air convergence blowing form of air convergence.

[0091] Therefore, in the air conditioner indoor unit 10 of the embodiment, the vertical structure of the front panel 130 is symmetrically arranged, which improves the appearance of the air conditioner indoor unit.

[0092] In another alternative embodiment, as shown in FIG. Figures 10-14 Figures 10-14 The front panel 130 is an arc-shaped panel with an opening facing backward, and the air outlet 150 is formed in the vertical middle lower side of the front panel 130, so that the air flow at the air outlet 150 has a tendency to blow obliquely downward.

[0093] In the alternative embodiment, when the plurality of air deflectors are in the air diffusion position, the air flow at the air outlet diffuses horizontally forward and downward and blows in a large range to achieve the air diffusion form of blowing forward and downward. In addition, when the plurality of air deflectors are in the air convergence position, the air flow at the air outlet converges forward and blows at a high speed to achieve the air convergence form of blowing forward and downward.

[0094] Therefore, the air inlet and outlet directions of the air conditioner indoor unit are rear air inlet and front and lower air outlet, when the air conditioner is arranged in the upper region of a room, the air outlet direction can be adapted to the arrangement position, the heat exchange efficiency of the air conditioner indoor unit is improved, and the user's use experience is further improved.
