[0037] As Figure 1 And Figure 2 The utility model discloses an air conditioner indoor unit 10 generally can include the shell 100, as shown in the specific embodiment of the utility model. Specifically, the shell 100 has the air inlet 140 and the air outlet 150 that are sequentially spaced in the front-back direction. Therefore, the air inlet and outlet direction of the air conditioner indoor unit 10 of the utility model is back air inlet front air outlet.

[0038] As Figures 3 to 7 The utility model discloses an air conditioner indoor unit 10 can also include multiple axial flow fans 200, as shown in the specific embodiment of the utility model.

[0039] Specifically, multiple axial flow fans 200 are arranged in the shell 100, for promoting the airflow entering the shell 100 from the air inlet 140 to blow out through the air outlet 150. That is, the air conditioner indoor unit 10 of the utility model embodiment is provided with multiple axial flow fans 200 between the air inlet 140 and the air outlet 150, for promoting the airflow entering the shell 100 from the air inlet 140 to flow forward and blow out through the air outlet 150.

[0040] In addition, the central axis of multiple axial flow fans 200 is inclined relative to the front-back direction of the shell 100, so that multiple axial flow fans 200 are inclined to front air outlet. That is, the central axis of multiple axial flow fans 200 is arranged from back to front left or right along the front-back direction of the shell 100.

[0041] In the present embodiment, as Figure 4 Or Figure 5 As shown, multiple axial flow fans 200 are arranged in an attitude that the central axis is inclined relative to the front-back direction of the shell 100, which increases the gap between the rear side and the left and right sides of multiple axial flow fans 200 and the shell 100, so as to increase the air inlet space of the left and right sides of multiple axial flow fans 200, thereby improving the air inlet amount of the left and right sides of multiple axial flow fans 200, and making the air outlet of multiple axial flow fans 200 converge to the front side middle area of multiple axial flow fans 200 while improving the air stealing problem of the middle area of the rear side of multiple axial flow fans 200.

[0042] The axial flow fans 200 in the air conditioner indoor unit 10 of the utility model are inclined and arranged oppositely, which increases the air inlet space of the two sides of the rear of the axial flow fans 200, improves the air stealing problem of the middle of multiple axial flow fans 200, and at the same time, the air outlet of multiple axial flow fans 200 converges to the middle of multiple axial flow fans 200, realizes concentrated air supply, thereby improving the overall air outlet speed of the air conditioner indoor unit 10, and further realizes the air supply effect that cold air blows farther and hot air is easier to fall to the ground, and improves the user's use experience.

[0043] In some embodiments, as shown in Figures 3 to 7 The plurality of axial flow fans 200 are arranged in the left-right direction of the shell 100 and the central axes of the plurality of axial flow fans 200 intersect at the front of the shell 100, so that the air flow blown by the plurality of axial flow fans 200 converges at the central position of the front of the shell 100.

[0044] Specifically, as shown in Figure 4 Or Figure 5 The plurality of axial flow fans 200 are arranged in the left-right direction of the shell 100 and the central axes of the plurality of axial flow fans 200 intersect at the front of the shell 100, so that the air flow blown by the plurality of axial flow fans 200 converges at the central position of the front of the shell 100.

[0045] In the air conditioner indoor unit 10 of the embodiments of the present application, the plurality of axial flow fans 200 are arranged in the left-right direction of the shell 100 and the central axes of the plurality of axial flow fans 200 intersect at the front of the shell 100, so that the air flow blown by the plurality of axial flow fans 200 converges at the central position of the front of the shell 100.

[0046] Therefore, the air conditioner indoor unit 10 of the present application converges the air flow blown by the plurality of axial flow fans 200 to the middle of the plurality of axial flow fans 200 by intersecting the central axes of the plurality of axial flow fans 200 at the front of the shell 100, improves the concentration of the air supply of the air conditioner indoor unit 10, and further improves the air supply speed of the air conditioner indoor unit 10.

[0047] In some embodiments, as shown in Figure 4 Or Figure 5 Specifically, the inclination angle of the central axis of each axial flow fan 200 relative to the front-rear direction of the shell 100 is selected from any value in the range of 2° to 10°. In one specific embodiment, the inclination angle of the central axis of each axial flow fan 200 relative to the front-rear direction of the shell 100 is 5°. Therefore, the included angle between the central axis of each axial flow fan 200 and the front-rear direction of the shell 100 is selected to be an appropriate angle, which reduces the occupied space of the axial flow fan 200 in the air conditioner indoor unit 10 while concentrating the air supply of the air conditioner indoor unit 10, and optimizes the space layout in the air conditioner indoor unit 10.

[0048] In some embodiments, as shown in Figure 7As shown, the rotation direction of each axial flow fan 200 is opposite to that of the axial flow fan 200 adjacent thereto, so that the air flows blown by the plurality of axial flow fans 200 converge in front of the shell 100.

[0049] Thus, when the plurality of axial flow fans 200 rotate reversely with adjacent axial flow fans 200, the air flows generated by each two adjacent axial flow fans 200 interact and superimpose in the air conditioner indoor unit 10, which enhances the disturbance and mixing of the air flows and improves the air flow circulation efficiency and uniformity in the air conditioner indoor unit 10. In addition, the reverse rotation of each two adjacent axial flow fans 200 reduces the collision and offset of the air flows when they meet, which improves the air supply distance of each axial flow fan 200 and the convergence of the air flows 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.

[0050] In some embodiments, as shown in Figures 3 to 7 As shown, in the air conditioner indoor unit 10 of the present application, the number of axial flow fans 200 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 intersect at the central position in front of the shell 100. Thus, the air flows of the two axial flow fans 200 converge at the central position in front of the shell 100. In addition, the rotation directions of the two axial flow fans 200 are opposite, so that the air flows blown by the plurality of axial flow fans 200 converge in front of the shell 100, thereby improving the air supply effect of the air conditioner indoor unit 10.

[0051] In some embodiments, as shown in Figures 3 to 5 and Figure 7 As shown, the air conditioner indoor unit 10 can further include a heat exchanger 300. Specifically, the heat exchanger 300 is arranged in the shell 100 between the axial flow fan 200 and the air outlet 150, and is used for heat exchange with the air flow 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 air flow 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.

[0052] Thus, the air conditioner indoor unit 10 of the present application embodiment realizes that the air flow 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, which improves the contact time and uniformity of the air flow with the heat exchanger 300 and thereby improves the heat exchange efficiency of the air conditioner indoor unit 10.

[0053] In some embodiments, as shown in Figure 4 The heat exchanger 300 can have a plurality of bending portions 310 arranged in sequence in the left-right direction of the shell 100, and the plurality of bending portions 310 are arranged one-to-one corresponding to the plurality of axial flow fans 200, and the size of each bending portion 310 in the left-right direction of the shell 100 is greater than the size of the axial flow fan 200 corresponding to it in the left-right direction of the shell 100. That is, the heat exchanger 300 can be designed in a bending style.

[0054] Specifically, as shown in Figure 3 and Figure 4 In the air conditioner indoor unit 10 of the utility model, the number of axial flow fans 200 can be two. Correspondingly, the number of bending portions 310 is two. Therefore, the two bending portions 310 are arranged one-to-one corresponding to the two axial flow fans 200, and the two bending portions 310 are arranged symmetrically in the left-right direction of the shell 100.

[0055] In one specific embodiment, as shown in Figure 4 The windward surface of each bending portion 310 is a plane, and is arranged vertically to the central axis of the axial flow fan 200 corresponding to it. Therefore, each bending portion 310 of the heat exchanger 300 is arranged to match the posture of the axial flow fan 200 corresponding to it, so as to more closely fit the heat exchanger 300 and the plurality of axial flow fans 200.

[0056] Therefore, the heat exchanger 300 and the plurality of axial flow fans 200 are arranged more closely, reducing the distance between the airflow blown by each axial flow fan 200 and the bending portion 310 of the heat exchanger 300 corresponding to it, 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.

[0057] In some embodiments, as shown in Figure 5 The heat exchanger 300 can also be arranged in a flat plate extending upward and downward, and the size of the heat exchanger 300 in the left-right direction of the shell 100 is greater than the size of the plurality of axial flow fans 200 in the left-right direction of the shell 100. That is, the heat exchanger 300 can be designed in a straight row type to save the overall thickness space of the air conditioner indoor unit 10.

[0058] Therefore, the heat exchanger 300 is arranged flatly in the shell 100, which improves the heat exchange efficiency of the air conditioner indoor unit 10, reduces the occupied space of the heat exchanger 300 in the air conditioner indoor unit 10, and further optimizes the space layout in the air conditioner indoor unit 10.

[0059] In some embodiments, as shown in Figures 3 to 8As shown, 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 to the side surface of the heat exchanger 300.

[0060] Therefore, in the air conditioner indoor unit 10 of the embodiment of the utility model, 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, reduces the turbulence and energy loss of the airflow, and 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 guided by the fan cover 400, and is more uniformly distributed on the surface of the heat exchanger 300, avoiding the phenomenon of local overheating or overcooling.

[0061] In some embodiments, as shown in the drawings, Figures 3 to 8 As shown, the fan cover 400 includes a plurality of flow guides 410 arranged in the left-right direction of the shell 100, and the plurality of flow guides 410 are arranged one-to-one with the plurality of axial flow fans 200. Each flow guide 410 and the heat exchanger 300 define an air outlet cavity 411 corresponding to the axial flow fan 200 corresponding thereto, so that the air outlet cavities 411 of the plurality of axial flow fans 200 are arranged separately. That is, the fan cover 400 includes a plurality of flow guides 410 arranged one-to-one with the axial flow fans 200, so that each axial flow fan 200 corresponds to an independent air outlet cavity 411.

[0062] Therefore, in the air conditioner indoor unit 10 of the embodiment of the utility model, each axial flow fan 200 corresponds to an independent air outlet cavity 411, thereby ensuring that the airflow generated by each axial flow fan 200 can be effectively guided to the heat exchanger 300 without mutual interference or mixing. The distribution of the airflow on the surface of the heat exchanger 300 is more uniform and orderly, thereby improving the heat exchange efficiency.

[0063] In addition, the fan cover 400 further includes an annular fan mounting portion 420 protruding rearward from the middle portion of the flow guide 410, and the fan mounting portion 420 is used to mount and fix the axial flow fan 200, so that the air outlet end of the axial flow fan 200 is connected with the flow guide 410 corresponding thereto.

[0064] Further, the air outlet cavity 411 is gradually expanded from back to front, so as to guide the airflow blown by the axial flow fan 200 to flow uniformly to the heat exchanger 300. That is, the air outlet diameter of the flow guide cover 410 gradually increases from back to front along the front-rear direction of the shell 100, so as to gradually expand the flow area of the airflow in the flow guide cover 410.

[0065] Therefore, the air conditioner indoor unit 10 of the embodiment of the present application, by setting the air outlet cavity 411 gradually expanded from back to front, the airflow blown by the axial flow fan 200 can be gradually dispersed and uniformized in the flow process, so as to ensure that the airflow can uniformly cover the entire surface of the heat exchanger 300, thereby improving the heat exchange efficiency of the air conditioner indoor unit 10.

[0066] At the same time, the air outlet cavity 411 is gradually expanded from back to front, which reduces the airflow resistance in the flow guide cover 410, helps to reduce the energy consumption of the axial flow fan 200, improves the energy efficiency ratio of the entire air conditioning system, and also reduces the turbulence and vortex generated in the flow process of the airflow, thereby reducing the noise level of the air conditioner indoor unit 10, and further improving the user's experience.

[0067] In some embodiments, as shown in Figures 1 to 5 and Figure 8 , the shell 100 can include a rear cover 110, an air outlet frame 120 and a front panel 130 arranged in sequence in the front-rear direction. Specifically, the air inlet 140 is arranged on the rear cover 110, and the air outlet 150 is arranged above the front panel 130 and / or below 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 mounting member 121 for mounting and fixing the heat exchanger 300 is inwardly protruded on the air outlet frame 120, so that the heat exchanger 300 is arranged in the air outlet frame 120. Therefore, the air inlet and outlet direction of the air conditioner indoor unit 10 of the embodiment of the present application is rear inlet and front outlet.

[0068] In one specific embodiment, as shown in Figures 2 to 5 and Figure 8 , 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 each direction of the rear of the shell 100.

[0069] Specifically, the plurality of air inlets 140 are uniformly and interval arranged 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.

[0070] Therefore, the air conditioner indoor unit 10 of the embodiment of the present application can increase the air inlet area through the plurality of air inlets 141 arranged at intervals on the outer circumferential side of the rear cover 110, thereby improving the air inlet efficiency, effectively dispersing the impact force when the airflow enters the shell 100, reducing the generation of noise, and improving the comfort and use experience of the user.

[0071] In some embodiments, as shown in Figure 8 Specifically, the upper air outlet 151 can be defined by the upper side edge of the front panel 130 and the top front side edge of the air outlet frame 120, so that the air conditioner indoor unit 10 can blow air upward and forward. In addition, the lower air outlet 152 is arranged at the bottom of the air outlet frame 120. In one specific embodiment, the lower air outlet 152 is arranged at the bottom front side of the air outlet frame 120, so that the air conditioner indoor unit 10 can blow air downward and forward.

[0072] Correspondingly, the air conditioner indoor unit 10 further comprises an upper air deflector 500 and a lower air deflector 600. The upper air deflector 500 is arranged at the upper air outlet 151 and is used to control the opening and closing of the upper air outlet 151 and adjust the air outlet direction of the upper air outlet 151. The lower air deflector 600 is arranged at the lower air outlet 152 and is used to control the opening and closing of the lower air outlet 152 and adjust the air outlet direction of the lower air outlet 152.

[0073] As shown in Figure 8 When the upper air deflector 500 and the lower air deflector 600 are both in the open position, the upper air outlet 151 and the lower air outlet 152 can blow air at the same time, so that the air conditioner indoor unit 10 blows air upward and downward and forward.

[0074] In addition, when the upper air deflector 500 is in the open position and the lower air deflector 600 is in the closed position, only the upper air outlet 151 blows air, so that the air conditioner indoor unit 10 blows air upward and forward.

[0075] When the upper air deflector 500 is in the closed position and the lower air deflector 600 is in the open position, only the lower air outlet 152 blows air, so that the air conditioner indoor unit 10 blows air downward and forward.

[0076] Therefore, the positions of the upper air deflector 500 and the lower air deflector 600 of the air conditioner indoor unit 10 of the present application can have multiple combinations, realizing the free combination adjustment of different air volume and different air direction, so that the air conditioner indoor unit 10 can have the diversified air blowing modes of blowing air upward and downward and forward, blowing air upward and forward, and blowing air downward and forward, effectively increasing the air outlet range, realizing the further optimization of the air blowing effect, and improving the use experience of the user.

[0077] It should be understood by those skilled in the art that, in some optional embodiments, the air conditioner indoor unit 10 of the present application can be a wall-mounted air conditioner indoor unit. Of course, in other optional embodiments, the air conditioner indoor unit 10 of the present application can also be a floor-standing air conditioner indoor unit.

[0078] It should also be understood by those skilled in the art that the "front", "back", "upper", "lower", "top", "bottom", "left", "right", "inner", "outer" and the like referred to in the embodiments of the present application indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application.
