[0037] The present invention provides a floor-standing air conditioner indoor unit, and the floor-standing air conditioner indoor unit can adjust the air supply angle of its air outlet to improve the air supply effect.

[0038] Please refer to Figure 1 and Figure 2 , in an embodiment of the floor-standing air conditioner indoor unit of the present invention, the floor-standing air conditioner indoor unit includes a housing 100, an air guide frame 500, and a flow guide cylinder 600. Among them, the housing 100 is provided with an air inlet 131, an air outlet 121, and an air duct 301 connecting the air inlet 131 and the air outlet 121. The air guide frame 500 is arranged in the air outlet direction of the air duct 301. The air guide frame 500 has a rotation axis extending in the up and down direction (such as L0 shown in Figure 9 , and the rotation axis L0 is a virtual line), and the air guide frame 500 can rotate around the rotation axis. The flow guide cylinder 600 is arranged in the air guide frame 500, and the flow guide cylinder 600 can swing and sweep the air along the extension direction of the rotation axis.

[0039] For the housing 100, the cross-section of the housing 100 intercepted by a plane perpendicular to its height direction is egg-shaped, that is, the rear end of the cross-section of the housing 100 is semi-circular, and its front end gradually narrows forward and is semi-elliptical. This can reduce the overall volume of the floor-standing air conditioner indoor unit, reduce the space occupied by its front end, and miniaturize the whole machine.

[0040] Specifically, the housing 100 includes a chassis 110, a front shell 120, a rear shell 130 and a front frame 140. Among them, the chassis 110, the front shell 120 and the rear shell 130 enclose a cavity, and the front frame 140 is installed in the cavity. A wind wheel assembly 200, a heat exchanger assembly 400, and a duct assembly 300 for forming a duct 301 are also installed in the cavity. When the floor-standing air conditioner indoor unit is working, the wind wheel assembly 200 drives air to enter the duct 301 of the housing 100 from the air inlet 131, and after being heat-exchanged by the heat exchanger assembly 400, it is blown from the duct 301 to the air deflector frame 500, and then is led out into the room by a flow guide cylinder 600 in the air deflector frame 500.

[0041] For the air deflector frame 500, the air deflector frame 500 is strip-shaped. The rotation axis of the air deflector frame 500 extends along the length direction of the air deflector frame 500 (that is, the up and down direction). The air deflector frame 500 includes two opposite side plates and two end plates connecting the two side plates. The two end plates and the two side plates enclose a wind guide cavity for accommodating the flow guide cylinder 600. When the air deflector frame 500 is driven to rotate around the rotation axis, it can drive the rotation along the left and right directions together, so as to realize the left and right sweeping (such as Figure 4 and Figure 5 ), and adjust the left and right air supply angles of the air outlet 121.

[0042] For the flow guide cylinder 600, the flow guide cylinder 600 is located in the wind guide cavity of the air deflector frame 500. The flow guide cylinder 600 is cylindrical, and the front and rear ends of the flow guide cylinder 600 are open, so that the air flow blown out from the duct 301 can enter from the rear end of the flow guide cylinder 600 and blow out from the front end of the flow guide cylinder 600. The flow guide cylinder 600 can swing along the extension direction of the rotation axis, that is, the flow guide cylinder 600 can swing along the up and down direction. When the flow guide cylinder 600 is driven to swing along the up and down direction, the up and down sweeping is realized, and further the up and down air supply angles of the air outlet 121 can be adjusted.

[0043] The technical solution of the present invention is to provide a wind guiding frame 500 and a flow guiding cylinder 600 arranged in the wind guiding frame 500 in the air outlet direction of the air duct 301 of the housing 100. The wind guiding frame 500 has a rotation axis extending in the vertical direction, and the wind guiding frame 500 can rotate around the rotation axis, so as to drive the flow guiding cylinder 600 to rotate around the rotation axis to achieve left and right sweeping; and the flow guiding cylinder 600 can swing and sweep along the extension direction of the rotation axis by itself, so as to achieve up and down sweeping. Thus, it can be seen that the floor-standing air conditioner indoor unit of the present invention can achieve multi-angle sweeping, and then direct the air flow blown out from the air duct 301 to different directions, with diverse air supply directions, effectively improving the air supply effect.

[0044] Compared with the conventional method of guiding the flow through the louvers, the floor-standing air conditioner indoor unit of the present invention uses the flow guiding cylinder 600 to guide the air flow of the air outlet, which can gather the air flow in the flow guiding cylinder 600 and blow it out, avoiding the diffusion of the air flow, making the air flow concentrated and directed to the designated air supply direction, and achieving a longer air supply distance.

[0045] Please refer to Figures 1 to 3 , based on the above embodiment, the floor-standing air conditioner indoor unit further includes a damper 700 located outside the wind guiding frame 500. The damper 700 can rotate circumferentially around the wind guiding frame 500 to open or close the air outlet 121 by rotating the damper 700. However, in view of the fact that the front end of the housing 100 of the floor-standing air conditioner indoor unit is semi-elliptically arranged, it is not easy for the damper 700 to rotate and move along the outer wall surface of the housing 100. Therefore, here, the damper 700 has a closed state of rotating to cover the air outlet 121 (as Figure 2 shown), and an open state of rotating to the inner side of the air duct 301 to open the air outlet 121 (as Figures 3 to 5 shown).

[0046] Please refer to Figure 1 and Figure 6 , for the convenience of installing the damper 700 and the wind guiding frame 500, the floor-standing air conditioner indoor unit further includes two installation parts respectively arranged on the upper and lower sides of the air outlet 121. The two ends of the wind guiding frame 500 are respectively rotationally connected to the two installation parts, and the inner wall surface of the damper 700 is slidably connected to the periphery of the installation part, so that the damper 700 can rotate circumferentially around the wind guiding frame 500.

[0047] Please refer to Figure 2 and Figure 3 , further, in order to ensure that the damper 700 can smoothly rotate into the air duct 301, optionally, the floor-standing air conditioner indoor unit further includes a volute 310 and a volute tongue 320. The inner surface of the volute tongue 320 is concave-arc-shaped in the direction away from the volute 310. When the damper 700 is in the open state, the damper 700 is received in the concave arc surface of the volute tongue 320.

[0048] Please refer to Figure 6 and Figure 7 Since, when the air damper 700 is in the open state, the air damper 700 is received in the concave arc surface of the volute tongue 320, the exposure of the air damper 700 on the outside can be avoided, thus preventing the overall appearance of the whole machine from being affected. Moreover, since the air damper 700 is also arc-shaped, the inner wall surface of the air damper 700 forms the air guiding surface of the air duct 301, and the air flow in the air duct 301 can be guided to the air outlet 121.

[0049] In addition, in order to prevent the front end of the volute 310 from drying out with the air guiding frame 500, a relief groove 302 is formed by the inner wall surface of the front end of the volute 310 recessing in the direction away from the volute 310, so as to avoid the air guiding frame 500 when the air guiding frame 500 rotates.

[0050] Please refer to Figures 6 to 8 Theoretically speaking, the air damper 700 and the air guiding frame 500 can rotate independently; or the air damper 700 and the air guiding frame 500 rotate in linkage through a linkage structure. However, in order to ensure that the air guiding frame 500 can independently adjust its rotation angle to achieve multi-angle air supply, optionally, the floor-standing air conditioner indoor unit further includes a second driving device 910 and a third driving device 920 installed on the installation part. The second driving device 910 and the third driving device 920 are respectively connected to the air damper 700 and the air guiding frame 500, so as to respectively drive the air damper 700 and the air guiding frame 500 to work independently through the second driving device 910 and the third driving device 920 without interference with each other.

[0051] Please refer to Figure 7 and Figure 9 Based on any of the above embodiments, for the air guiding frame 500, the floor-standing air conditioner indoor unit further includes an air guiding grille 520 provided on the front side of the air guiding frame 500. The air guiding frame 500 includes a frame body 510 and an air guiding grille 520 provided on the front side of the frame body 510. The air guiding grille 520 includes a plurality of horizontal grille bars 521 and vertical grille bars 522 connecting the plurality of horizontal grille bars 521. Among them, the horizontal grille bars 521 are convex-arc-shaped away from the air guiding cylinder 600 to match the shape of the air guiding frame 500. The air guiding grille 520 can not only guide the air flow blown out from the air guiding frame 500 to a specified direction, but also can act as a reinforcing rib of the air guiding frame 500, effectively increasing the strength of the air guiding frame 500.

[0052] The cross-section of the air guiding frame 500 is semi-circular or arc-shaped, so as to form an arc-shaped air outlet surface on the air outlet side of the air guiding frame 500, effectively increasing the air outlet area, further expanding the air supply range and improving the air supply effect. Moreover, there are no corners or edges on the circumference of the air guiding frame 500, so that during the rotation of the air guiding frame 500, it is not easy to interfere with the structures (such as the volute 310 or the volute tongue 320 of the air duct assembly 300) around the air outlet 121.

[0053] To improve the air guiding effect of the air guiding frame 500, in other embodiments, the plate surface of any one side plate of the air guiding frame 500 can be set to be arc-shaped, and the two side plates cooperate to surround the air guiding cylinder 600, which is used to guide the air flow blown out from the air duct 301 to the air guiding cylinder 600 to improve the air guiding efficiency.

[0054] Please refer to Figure 7 、 Figure 10 and Figure 11 Based on any of the above embodiments, for the air guiding cylinder 600, the air guiding cylinder 600 of the air guiding cylinder 600 can have various shape and structure designs. For example but not limited to, the radial cross-section of the air guiding cylinder 600 is circular, or elliptical, or polygonal, as long as its two ends are open for air flow to pass through. As for the number of the air guiding cylinders 600 of the air guiding cylinder 600, it can be one or more than two.

[0055] Please refer to Figure 7 、 Figure 10 and Figure 11 In an embodiment, the number of the air guiding cylinders 600 is multiple, and the multiple air guiding cylinders 600 are arranged at intervals along the extending direction of the rotation axis. Each air guiding cylinder 600 has two opposite side walls 630, and the two side walls 630 are rotatably connected to the air guiding frame 500 so that the air guiding cylinder 600 can swing up and down to realize up and down air sweeping.

[0056] Further, the floor-standing air conditioner indoor unit further includes a first driving device 800. The first driving device 800 includes a motor 810 and a connecting rod 820. The connecting rod 820 is hinged to the multiple air guiding cylinders 600, and the motor 810 is connected to one end of the connecting rod 820 to drive the connecting rod 820 to move along the extending direction of the rotation axis, thereby driving the multiple air guiding cylinders 600 to swing.

[0057] Specifically, the rear ends of the multiple air guiding cylinders 600 are all hinged to the connecting rod 820. When the motor 810 drives the connecting rod 820 to move upward, the rear ends of the multiple air guiding cylinders 600 move upward with the connecting rod 820, so that the front ends of the multiple air guiding cylinders 600 move relatively downward, and then the whole air guiding cylinder 600 swings relatively downward to sweep the air, and at this time, the air flow can be blown downward. On the contrary, when the motor 810 drives the connecting rod 820 to move downward, the air flow can be blown upward.

[0058] Please refer to Figure 7 、 Figure 10 and Figure 11, Based on this, the draft tube 600 has a bottom wall 610 and a top wall 620, and either the bottom wall 610 or the top wall 620 can be hinged to the connecting rod 820 to swing driven by the connecting rod 820. However, it is considered here that during the movement of the draft tube 600 together with the connecting rod 820, one of the bottom wall 610 and the top wall 620 that is not connected to the connecting rod 820 may interfere with the connecting rod 820 during the movement, causing the swing of the draft tube 600 to be blocked.

[0059] To avoid the occurrence of the above situation, either the bottom wall 610 or the top wall 620 of the draft tube 600 is hinged to the connecting rod 820, and the other is provided with a first notch groove 601 corresponding to the connecting rod 820 for avoiding the connecting rod 820 when the draft tube 600 swings.

[0060] Specifically here, the bottom wall 610 of the draft tube 600 is hinged to the connecting rod 820, and the top wall 620 of the draft tube 600 is provided with a first notch groove 601. When the connecting rod 820 drives the rear end of the draft tube 600 to move downward, the front end of the draft tube 600 moves relatively upward, realizing the overall upward air sweeping of the draft tube 600; during this process, the top wall 620 of the draft tube 600 approaches the connecting rod 820, and the connecting rod 820 enters the first notch groove 601 of the top wall 620, thus avoiding the situation where the top wall 620 abuts against the connecting rod 820 and causing the swing of the draft tube 600 to be blocked.

[0061] In addition, since one end (i.e., the front end) of the draft tube 600 is close to the air deflector grille 520, in order to avoid interference between the draft tube 600 and the longitudinal grille bars 522 of the air deflector grille 520 during rotation, the end of the draft tube 600 close to the air deflector grille 520 is provided with a second notch groove 602 for avoiding the longitudinal grille bars 522.

[0062] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present invention.
