Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and particularly relates to a floor-standing air conditioner indoor unit and an air conditioner. Background Art

[0002] For existing floor-standing air conditioners, the air supply mode is relatively single. However, with the improvement of living quality and the increasing requirements of users for comfort and physical sensation, the single air supply mode is increasingly difficult to meet the needs of users. For example, when the indoor environmental temperature is maintained within a relatively comfortable range, if the cold or hot air blows on a person, the wind force will be felt to be strong. Especially when the strong cold air blows on the user, the comfort of the air conditioner will be reduced.

[0003] Currently, to achieve a windless feeling at the air outlet of a floor-standing air conditioner, usually the method of punching holes in the air guide strip or louver is adopted. When the air guide strip or louver rotates to form a 90-degree angle with the air outlet direction, that is, when the air outlet is closed, the air flow from the air outlet can be intercepted and dispersed by the micro-holes, so as to shorten the air supply distance and weaken the air flow, and avoid the problem of discomfort caused by strong air flow blowing. However, with this method, due to the small diameter of the micro-holes, the wind resistance is large, the air volume loss is very large, the power consumption is high, and there are problems such as difficult adjustment of the strength of the windless feeling air flow and uncontrollable direction divergence.

[0004] The above content is only used to assist in understanding the technical solution of the invention, and does not represent an admission that the above content is prior art. Summary of the Invention

Taking "A and / or B" as an example, it includes solution A, or solution B, or a solution where A and B are satisfied simultaneously.

[0046] The present invention provides a floor-mounted air conditioner indoor unit.

[0047] In the embodiments of the present invention, as Figures 1 to 10As shown in the figure, the floor-mounted air conditioner indoor unit includes a housing 100, a wind-dispersing assembly 200, and a first driving device 300. The housing 100 has an air outlet 110 extending in the up-down direction. The wind-dispersing assembly 200 is rotatably mounted on the housing 100, and has a first position where it rotates to at least partially cover the air outlet 110 and a second position where it moves away from the air outlet 110 and hides inside the housing 100. The wind-dispersing assembly 200 includes a mounting plate 210 and a swirl air wheel 220. A mounting through hole 211 is formed in the mounting plate 210, and the swirl air wheel 220 is correspondingly mounted at the mounting through hole 211. One end of the mounting plate 210 is connected with a horizontally arranged first rotating arm 230. The first driving device 300 includes a first driving member 310 and a first transmission member 320. The end of the first rotating arm 230 is connected with the first transmission member 320, and the first driving member 310 is connected with the first transmission member 320 to drive the first transmission member 320 to drive the wind-dispersing assembly 200 to switch between the first position and the second position.

[0048] In this embodiment, the housing 100 extends integrally in the up-down direction. The shape of the horizontal cross-section of the housing 100 can be circular, elliptical, rectangular, etc., which can be selected according to actual use requirements and will not be specifically limited here. The shape of the air outlet 110 can be a long rectangular shape or a long elliptical shape, etc. The long-strip air outlet 110 can increase the air supply volume and the air supply range. The housing 100 also has an air inlet and a duct connecting the air inlet and the air outlet 110.

[0049] The overall shape of the wind-dispersing assembly 200 is adapted to the shape of the air outlet 110. The wind-dispersing assembly 200 extends in the up-down direction, so the mounting plate 210 is also in a long-strip shape and extends in the up-down direction. In order to ensure that the air flow blown out from the mounting through hole 211 is all the air flow scattered by the swirl air wheel 220, it is preferably that the mounting through hole 211 is circular and is adapted to the size of the swirl air wheel 220. The swirl air wheel 220 can be fixedly connected to the mounting through hole 211 of the mounting plate 210, or can be rotatably connected to the mounting through hole 211 of the mounting plate 210, and the rotation axis of the swirl air wheel 220 can be parallel or perpendicular to the mounting through hole 211. The swirl air wheel 220 is specifically an axial flow air wheel. In some embodiments, two layers of air wheels can also be provided, with one layer being a static air wheel and the other layer being a dynamic air wheel. It can be understood that the swirl air wheel 220 means that the blades of the swirl air wheel 220 are curved or are arranged at an angle to the air inlet direction, so that the air flow passing through the swirl air wheel 220 forms a swirl, or the air inlet direction is inconsistent with the air outlet direction. In this way, the air flow of the air outlet can be effectively scattered and agitated, making the air outlet softer, with small air resistance and air loss, and the air volume without wind feeling can be effectively improved.

[0050] The air-diffusing assembly 200 is rotatably connected to the housing 100, and specifically, it can be realized through structures such as an annular chute and slide rail, a gear and rack, etc., as long as it can realize the rotational switching between the first position and the second position. It should be noted that the air-diffusing assembly 200 covering the air outlet 110 means that the plate surface of the mounting plate 210 blocks the air outlet 110. In this way, after the air flow passes through the air-diffusing assembly 200, it blows out from the mounting through-hole 211. In order to improve the effect of no wind feeling, when the air-diffusing assembly 200 is in the first position, most or all of the mounting plate 210 of the air-diffusing assembly 200 should cover the air outlet 110, so that most or all of the air flow is dispersed and stirred by the swirl air wheel 220 of the mounting through-hole 211 and then flows out. When the air-diffusing assembly 200 rotates to the first position where at least part of it covers the air outlet 110, due to the air-diffusing and flow-expanding effect of the swirl air wheel 220 of the air-diffusing assembly 200, the air flow blown out from the air outlet 110 is a no wind feeling or a slight wind feeling, so that the whole machine is in the slight wind feeling mode. When the air-diffusing assembly 200 rotates to move away from the air outlet 110 and hides in the housing 100 at the second position, that is, the air-diffusing assembly 200 does not block the air outlet 110. In this way, the air flow in the air duct is unobstructed and directly blows out from the air outlet 110 after the air guiding effect of the louvers and / or the vertical air guiding plate, solving the problem of the air-diffusing assembly 200 blocking the wind and realizing the conventional air outlet mode of the whole machine to meet the requirements of rapid heating and cooling. By hiding the air-diffusing assembly 200 in the housing 100 and making full use of the space in the housing 100 to place the air-diffusing assembly 200, the overall appearance consistency of the whole machine can be maintained.

[0051] A first rotating arm 230 arranged horizontally is provided at the end of the mounting plate 210, and the first rotating arm 230 can be provided at the upper end and / or the lower end of the mounting plate 210. The first rotating arm 230 is arranged horizontally as a whole, that is, the first rotating arm 230 is arranged horizontally as a whole. The first rotating arm 230 can be located on the same horizontal plane as a whole, or can be arranged in a stepped plane shape with a stepped structure, that is, the first rotating arm 230 is partially bent in the up and down directions, as long as the first rotating arm 230 extends horizontally as a whole. The shape of the first rotating arm 230 can be roughly L-shaped, U-shaped, linear, etc., and is not specifically limited here. By connecting the end of the first rotating arm 230 to the first transmission member 320, the first driving member 310 drives the first transmission member 320 to drive the air-diffusing assembly 200 to switch between the first position and the second position. Then the air-diffusing assembly 200 realizes the connection with the first transmission member 320 through the first rotating arm 230, avoiding the direct connection between the mounting plate 210 of the air-diffusing assembly 200 and the first transmission member 320, so that there is enough space between the mounting plate 210 and the first transmission member 320 in the horizontal direction.

[0052] The floor-mounted air conditioner indoor unit of the present invention can effectively disperse and stir the air flow through the swirl air wheel 220 of the air dispersion component 200, so that the air flow blown out from the air outlet 110 achieves a draft-free effect, with a large air volume, small air resistance, low noise and low power consumption. And the mounting plate 210 of the air dispersion component 200 is connected to the first transmission member 320 through the horizontally arranged first rotating arm 230, avoiding direct contact between the mounting plate 210 and the first transmission member 320, so that there is enough spacing between the mounting plate 210 and the first transmission member 320 in the horizontal direction, that is, the air dispersion component 200 has enough rotation space and will not interfere with the first transmission member 320, thereby ensuring the rotation stability of the air dispersion component 200 and the system stability.

[0053] Specifically, please refer to Figures 8 to 11 , the first driving device 300 includes a first mounting box 330 installed on the housing 100. The first transmission member 320 includes a first gear 321 and a first arc-shaped rack 322 installed in the first mounting box 330. The first driving member 310 is a driving motor, the driving motor is drivingly connected to the first gear 321, the first gear 321 meshes with the first arc-shaped rack 322, and the end of the first rotating arm 230 is connected to the first arc-shaped rack 322.

[0054] In this embodiment, in order to facilitate the installation and disassembly of the first transmission member 320, the first mounting box 330 is provided with a structure formed by splicing two box bodies. In order to reduce the occupied space of the first mounting box 330, the first mounting box 330 is arranged in a disk shape. The driving motor can be installed inside the first mounting box 330 or outside the first mounting box 330. In order to reduce the occupied space of the first mounting box 330, the driving motor is installed outside the first mounting box 330. It can be understood that the length of the first arc-shaped rack 322 is greater than the moving stroke of the air dispersion component 200 when switching between the first position and the second position to meet the rotation requirement of the air dispersion component 200. The rotation of the air dispersion component 200 is realized through the structure of the driving motor, the first gear 321 and the first arc-shaped rack 322, with a simple and reliable structure, small occupied space and easy to implement. Of course, in other embodiments, the first transmission member 320 can also be a crank and connecting rod mechanism, which can also realize driving the air dispersion component 200 to switch between the first position and the second position.

[0055] On the basis of the above embodiments, further, as Figure 10 and Figure 11 shown, the first driving device 300 further includes a first slider 340 arranged outside the first mounting box 330. A first sliding groove 331 is opened on the first mounting box 330. The first slider 340 is fixedly connected to the first arc-shaped rack 322 through a first sliding column 350. The first sliding column 350 is arranged through the first sliding groove 331, and the end of the first rotating arm 230 is connected to the first slider 340.

[0056] In this embodiment, the first slider 340 can be arranged on the top surface, bottom surface or side wall surface of the first mounting box 330. To increase the structural strength, preferably, the first slider 340 is arranged on the top surface or bottom surface of the first mounting box 330. It can be understood that when the first driving device 300 is arranged at the bottom of the air-diffusing assembly 200, the first slider 340 is preferably mounted on the top surface of the first mounting box 330. When the first driving device 300 is arranged at the top of the air-diffusing assembly 200, the first slider 340 is preferably mounted on the bottom surface of the first mounting box 330. To make the structure more compact and reduce the occupied space, preferably, the first slider 340 is arranged in an arc shape. And the shape of the first slider 340 is adapted to the shape of the first arc-shaped rack 322. The first sliding column 350 can be fixedly connected to one of the first arc-shaped rack 322 and the first slider 340, such as by integral molding, and detachably connected to the other, such as by plugging or sleeving. It can be understood that after the first slider 340 is connected to the first arc-shaped rack 322 through the first sliding column 350, there is a gap between the first slider 340 and the first mounting box 330, thereby reducing the friction between the first slider 340 and the first mounting box 330. The first slider 340 is connected to the first arc-shaped rack 322 through the first sliding column 350, and the first sliding column 350 is arranged to pass through the first sliding groove 331 of the first mounting box 330. On the one hand, it is convenient for the disassembly and assembly of the first slider 340 and the first arc-shaped rack 322. On the other hand, it is convenient for the sliding of the first slider 340, and provides limit and guidance for the sliding of the first slider 340. The number of the first sliding columns 350 can be one or more. When the number of the first sliding columns 350 is multiple, the multiple first sliding columns 350 are arranged at intervals along the extending direction of the first sliding groove 331.

[0057] Specifically, please refer to Figure 9 and Figure 10 , the first rotating arm 230 includes a first arc segment, a second arc segment arranged oppositely, and a connecting segment connecting the first arc segment and the second arc segment. One end of the first arc segment far from the connecting segment is connected to the mounting plate 210 of the air-diffusing assembly 200, and one end of the second arc segment far from the connecting segment is connected to the first slider 340. To make the overall structure more compact and reduce the occupied space, preferably, the shapes of the second arc segment, the first slider 340 and the first arc-shaped rack 322 are adapted to each other.

[0058] In one embodiment, please refer to Figures 8 to 10, first rotating arms 230 are connected to both the upper end and the lower end of the mounting plate 210. The floor-standing air conditioner indoor unit is provided with two sets of first driving devices 300, and each first driving device 300 is connected to a first rotating arm 230 to synchronously drive the air-diffusing assembly 200 to rotate. It can be understood that since the air-diffusing assembly 200 is integrally long and extends in the up-down direction, and it is relatively heavy, by connecting first rotating arms 230 to both the upper end and the lower end of the mounting plate 210, and connecting the first rotating arms 230 through two first driving devices 300 respectively to synchronously drive the air-diffusing assembly 200 to rotate, the rotation stability of the air-diffusing assembly 200 can be effectively improved, thereby avoiding situations such as the air-diffusing assembly 200 tilting or jamming.

[0059] In one embodiment, as Figure 6 and Figure 7 shown, the width of the mounting plate 210 is smaller than the width of the air outlet 110. It can be understood that when the air-diffusing assembly 200 is in the second position, the whole air-diffusing assembly 200 is hidden on one side of the housing 100, usually on the left and right sides of the air outlet 110. Since the floor-standing air conditioner indoor unit further includes a switch door 400 for opening or closing the air outlet 110, the width of the switch door 400 should be greater than or equal to the width of the air outlet 110. Usually, there is a relatively large space between the air duct housing and the volute housing, which can allow the switch door 400 to move, while the space on the other side is smaller for the air-diffusing assembly 200 to move. Thus, in order to make the overall structure more compact, the width of the mounting plate 210 is set to be smaller than the width of the air outlet 110. In this way, while meeting the requirement that the floor-standing air conditioner indoor unit has a draft-free mode, when the air-diffusing module is not needed, the air-diffusing module can be hidden in the remaining space on the side of the housing 100 opposite to the switch door 400 without increasing the volume of the whole machine.

[0060] In one embodiment, please refer to Figures 1 to 6 , the cross-section of the housing 100 is circular. The floor-standing air conditioner indoor unit further includes a switch door 400, and the switch door 400 is rotatably mounted on the housing 100 along the circumferential direction of the housing 100 to open or close the air outlet 110. And when the switch door 400 opens the air outlet 110 and the air-diffusing assembly 200 moves to the second position, the switch door 400 and the air-diffusing assembly 200 are respectively located on opposite sides in the width direction of the air outlet 110 and are inside the housing 100.

[0061] In this embodiment, specifically, an air duct housing is disposed inside the housing 100. The air duct housing encloses to form an air duct communicating with the air outlet 110. An air wheel is disposed in the air duct, and a heat exchanger is disposed outside the air duct at a position corresponding to the air inlet of the housing 100. There is a first installation space between the outer wall surface of the air duct housing away from the heat exchanger and the inner wall surface of the housing 100. There is a second installation space between the end of the heat exchanger away from the air duct housing and the inner wall surface of the housing 100, and the first installation space and the second installation space are located on both sides in the width direction of the air outlet 110. Since the first installation space is larger than the second installation space, when the switch door 400 is opened, the switch door 400 can move within the first installation space. When the air diffusing assembly 200 moves to the second position, that is, avoiding the air outlet 110, the air diffusing assembly 200 can move to the second installation space. Thus, the space between the air duct housing and the housing 100, and between the heat exchanger and the housing 100 is fully utilized, making the overall structure of the machine more compact. To maintain the overall consistency of the appearance, the air diffusing assembly 200 and / or the switch door 400 can be integrally formed into a convex arc structure. When the air diffusing assembly 200 and the switch door 400 move to the position corresponding to the air outlet 110, the air diffusing assembly 200 and the housing 100 or the switch door 400 and the housing 100 integrally form a cylindrical structure. Since the air duct is in an arc structure, the switch door 400 rotates circumferentially to open or close the air outlet 110, and the air diffusing assembly 200 switches between the first position and the second position circumferentially, fully utilizing the space in the circumferential direction of the housing 100, thus saving other spaces inside the housing 100 and making the structure inside the housing 100 more compact.

[0062] In one embodiment, please also refer to Figures 8 to 11 , the floor-standing air conditioner indoor unit further includes a second driving device 500. A laterally disposed second rotating arm 410 is connected to the end of the switch door 400. The second driving device 500 includes a second driving member 510 and a second transmission member 520. The end of the second rotating arm 410 is connected to the second transmission member 520, and the second driving member 510 is connected to the second transmission member 520 to drive the second transmission member 520 to drive the switch door 400 to open or close the air outlet 110.

[0063] In this embodiment, a second rotating arm 410 arranged horizontally is provided at the end of the switch door 400, and the second rotating arm 410 can be provided at the upper end and / or the lower end of the switch door 400. The second rotating arm 410 is arranged horizontally as a whole, that is, the second rotating arm 410 is arranged horizontally as a whole. The second rotating arm 410 can be located on the same horizontal plane as a whole, or can be arranged in a stepped plane shape with a stepped structure, that is, the second rotating arm 410 is partially bent in the up and down directions, as long as the second rotating arm 410 extends horizontally as a whole. The shape of the second rotating arm 410 can be approximately L-shaped, U-shaped, linear, etc., and is not specifically limited here. By connecting the end of the second rotating arm 410 to the second transmission member 520, the second driving member 510 drives the second transmission member 520 to drive the switch door 400 to close or open the air outlet 110. Then the switch door 400 is connected to the first transmission member 320 through the second rotating arm 410, avoiding the direct connection between the switch door 400 and the second transmission member 520, so that there is enough space between the switch door 400 and the second transmission member 520 in the horizontal direction. In addition, both the switch door 400 and the air-diffusing assembly 200 are connected to the transmission member through the rotating arm, so that the rotations of the switch door 400 and the air-diffusing assembly 200 do not interfere with each other, thereby improving the operating stability of the entire system.

[0064] Specifically, please refer to Figure 10 and Figure 11 , the second driving device 500 includes a second mounting box 530 installed in the housing 100, the second transmission member 520 includes a second gear 521 and a second arc-shaped rack 522 installed in the second mounting box 530, the second driving member 510 is a driving motor, the driving motor is drivingly connected to the second gear 521, the second gear 521 meshes with the second arc-shaped rack 522, and the end of the second rotating arm 410 is connected to the second arc-shaped rack 522.

[0065] In this embodiment, for the convenience of installation and disassembly of the second transmission member 520, the second installation box 530 is configured as a structure formed by splicing two box bodies. To reduce the occupied space of the second installation box 530, the second installation box 530 is arranged in a disc shape. The drive motor can be installed inside the second installation box 530 or outside the second installation box 530. To reduce the occupied space of the second installation box 530, the drive motor is installed outside the second installation box 530. It can be understood that the length of the second arc-shaped rack 522 is greater than the moving stroke of the switch door 400 when switching between the positions of opening and closing the air outlet 110, so as to meet the rotation requirement of the switch door 400. The rotation of the switch door 400 is realized through the structure of the drive motor, the second gear 521 and the second arc-shaped rack 522. The structure is simple and reliable, occupies a small space and is easy to implement. Of course, in other embodiments, the second transmission member 520 can also be a crank-link mechanism, which can also drive the switch door 400 to switch the positions of opening and closing the air outlet 110.

[0066] Based on the above embodiment, further, please refer to again Figure 10 and Figure 11 , the second driving device 500 further includes a second slider 540 arranged outside the second installation box 530. A second sliding groove 531 is formed on the second installation box 530. The second slider 540 and the second arc-shaped rack 522 are fixedly connected through a second sliding column 550. The second sliding column 550 is arranged through the second sliding groove 531. The end of the second rotating arm 410 is connected to the second slider 540.

[0067] In this embodiment, the second slider 540 can be disposed on the top surface, bottom surface or side wall surface of the second mounting box 530. To increase the structural strength, preferably, the second slider 540 is disposed on the top surface or bottom surface of the second mounting box 530. It can be understood that when the second driving device 500 is disposed at the bottom of the switch door 400, the second slider 540 is preferably mounted on the top surface of the second mounting box 530. When the second driving device 500 is disposed at the top of the switch door 400, the second slider 540 is preferably mounted on the bottom surface of the second mounting box 530. To make the structure more compact and reduce the occupied space, preferably, the second slider 540 is arc-shaped. And the shape of the second slider 540 is adapted to the shape of the second arc-shaped rack 522. The second sliding column 550 can be fixedly connected to two of the second arc-shaped rack 522 and the second slider 540, such as by integrally molding, and detachably connected to the other, such as by plugging or sleeving. It can be understood that after the second slider 540 is connected to the second arc-shaped rack 522 through the second sliding column 550, there is a gap between the second slider 540 and the second mounting box 530, thereby reducing the friction between the second slider 540 and the second mounting box 530. The second slider 540 is connected to the second arc-shaped rack 522 through the second sliding column 550, and the second sliding column 550 is disposed through the second sliding groove 531 of the second mounting box 530. On the one hand, it is convenient for the disassembly and assembly of the second slider 540 and the second arc-shaped rack 522. On the other hand, it is convenient for the sliding of the second slider 540, and provides limit and guidance for the sliding of the second slider 540. The number of the second sliding columns 550 can be one or more. When the number of the second sliding columns 550 is multiple, the multiple second sliding columns 550 are arranged at intervals along the extending direction of the second sliding groove 531.

[0068] Specifically, as Figure 9 and Figure 10 shown, the second rotating arm 410 includes a third arc segment, a fourth arc segment disposed opposite to each other, and a transition segment connecting the third arc segment and the fourth arc segment. One end of the third arc segment away from the transition segment is connected to the end of the switch door 400, and one end of the fourth arc segment away from the transition segment is connected to the second slider 540. To make the overall structure more compact and reduce the occupied space, preferably, the shapes of the fourth arc segment, the second slider 540 and the second arc-shaped rack 522 are adapted to each other.

[0069] In one embodiment, second rotating arms 410 are connected to both the upper end and the lower end of the switch door 400. The floor-standing air conditioner indoor unit is provided with two sets of second driving devices 500, and each second driving device 500 is connected to a second rotating arm 410 to synchronously drive the switch to rotate. It can be understood that since the switch door 400 is integrally long and extends in the up-and-down direction, and it is relatively heavy, by connecting second rotating arms 410 to both the upper end and the lower end of the switch door 400, and respectively connecting the second rotating arms 410 through two second driving devices 500 to synchronously drive the switch door 400 to rotate, the rotation stability of the switch door 400 can be effectively improved, thereby avoiding situations such as the switch door 400 tilting or jamming.

[0070] In one embodiment, please refer to Figures 8 to 11 , the first driving device 300 and the second driving device 500 are arranged in sequence in the up-and-down direction, and the switch door 400 and the mounting plate 210 are spaced apart and arranged at an angle in the circumferential direction of the housing 100. By arranging the first driving device 300 and the second driving device 500 in the up-and-down direction, the space in the up-and-down direction of the housing 100 is fully utilized, making the structure of the whole machine more compact. By arranging the switch door 400 and the mounting plate 210 at an angle in the circumferential direction, there will be no interference when the first driving device 300 drives the air-diffusing assembly 200 to rotate and the second driving device 500 drives the switch door 400 to rotate, meeting the respective rotation requirements of both and ensuring the operation stability of the system.

[0071] In one embodiment, as Figure 6 and Figure 7 shown, the floor-standing air conditioner indoor unit further includes a wind deflector assembly 600 correspondingly arranged at the air outlet 110. The wind deflector assembly 600 includes a plurality of wind deflectors arranged along the width direction of the air outlet 110. The wind deflectors extend in the up-and-down direction and are rotatable about a vertical axis;

[0072] When the air-diffusing assembly 200 is in the first position, the plurality of wind deflectors open the air outlet 110. The air-diffusing assembly 200 is located downstream of the wind deflector assembly 600 in the air outlet direction of the air outlet 110, and the wind deflector adjacent to one side edge of the air outlet 110 overlaps with the side edge of the air-diffusing assembly 200.

[0073] In this embodiment, multiple air deflector plates can rotate around a vertical axis, and the left and right air guiding is achieved by the air deflector plates. The air dispersing assembly 200 is located downstream of the air deflector plate assembly 600 in the air outlet direction of the air outlet 110, that is, the air dispersing assembly 200 is located outside the air deflector plate assembly 600. It can be understood that when the floor-standing air conditioner indoor unit is in the gentle breeze feeling mode, the air deflector plate opens the air outlet 110 to guide the air flow to the air dispersing assembly 200. The air deflector plate overlaps the side of the air dispersing assembly 200, that is, the side of the mounting plate 210 in the left-right direction. The air deflector plate overlaps the side of the air dispersing assembly 200 outward, so that on the one hand, the air leakage gap is reduced by the cooperation of the air deflector plate and the mounting plate 210, and on the other hand, the air flow is guided to the mounting plate 210 by the air deflector plate, thereby improving the draft-free effect of the air dispersing assembly 200.

[0074] Specifically, please refer to Figure 3 and Figure 7 . A plurality of air dispersing holes 630 are formed in the air deflector plate. By providing a plurality of air dispersing holes 630 on the air deflector plate, while realizing the left and right air guiding, when the floor-standing air conditioner indoor unit is in the gentle breeze feeling mode, that is, when the air guiding strip rotates to overlap with the mounting plate 210 of the air dispersing assembly 200, the air dispersing holes 630 on the air guiding strip can also disperse the air flow, thereby improving the draft-free effect.

[0075] Combined with the above embodiment in which the floor-standing air conditioner indoor unit is provided with an air deflector plate assembly 600, further, as Figure 6 and Figure 7 shown, the air deflector plate assembly 600 includes a first air deflector plate 610 and a second air deflector plate 620. The width direction of the air outlet 110 has opposite first side 111 and second side 112. The first air deflector plate 610 is arranged close to the first side 111, the second air deflector plate 620 is arranged close to the second side 112. The first air deflector plate 610 overlaps with the side of the air dispersing assembly 200 close to the first side 111, and the second air deflector plate 620 overlaps with the side of the air dispersing assembly 200 close to the second side 112.

[0076] In this embodiment, the width direction of the air outlet 110 has a first side 111 and a second side 112, that is, the left side and the right side of the air outlet 110. The first air deflector plate 610 is the leftmost air deflector plate in the air deflector plate assembly 600, and the second air deflector plate 620 is the rightmost air deflector plate in the air deflector plate assembly 600. By overlapping the first air deflector plate 610 with the left side of the mounting plate 210 of the air dispersing assembly 200 and the second air deflector plate 620 with the right side of the mounting plate 210 of the air dispersing assembly 200, a dispersed air outlet cavity is formed, which can effectively guide all or most of the air flow at the air outlet 110 to the air dispersing assembly 200, so that the air flow blown out from the air outlet 110 is all air flow that has been dispersed and diffused, thereby achieving a better draft-free effect.

[0077] Further, please refer to Figure 7 , on the inner wall surfaces of the mounting plate 210 near the first side 111 and near the second side 112, there are convex lapping portions 212 for lapping the first air guide plate 610 and the second air guide plate 620. Lapping portions 212 are provided on both sides in the width direction of the mounting plate 210 for lapping the first air guide plate 610 and the second air guide plate 620, preventing the first air guide plate 610 and the second air guide plate 620 from disengaging from the mounting plate 210 under the action of air flow, making the lapping between the first air guide plate 610 and the mounting plate 210, and the lapping between the second air guide plate 620 and the mounting plate 210 more stable, and playing a role in supporting and limiting the lapping of the first air guide plate 610 and the second air guide plate 620. The lapping portion 212 can be integrally formed with the mounting plate 210 or can be formed separately. The lapping portion 212 can be made of a metal material or can be made of an elastic material such as rubber.

[0078] In an embodiment, the floor-standing air conditioner indoor unit further includes an independent third driving device and a fourth driving device. The third driving device is connected to the first air guide plate 610 to drive the first air guide plate 610 to rotate to lap inside the lapping portion 212, and the fourth driving device is connected to the second air guide plate 620 to drive the second air guide plate 620 to rotate to lap inside the lapping portion 212.

[0079] In this embodiment, the third driving device and the fourth driving device can specifically be driving motors. It can be understood that when the gentle breeze mode needs to be turned on, before the air diffusing assembly 200 moves from the second position to the first position, the air guide plates of the air guide plate assembly 600 rotate to a position approximately 90 degrees to the air outlet direction of the air outlet 110, that is, the position of closing the air outlet 110. When the air diffusing assembly 200 moves to the first position, that is, moves to the air outlet 110, the first air guide plate 610 is driven to rotate by the third driving device, and the second air guide plate 620 is driven to rotate in the opposite direction to the first air guide plate 610 by the fourth driving device, so as to lap the first air guide plate 610 and the second air guide plate 620 inside the lapping portion 212, thereby realizing the gentle breeze mode. In this way, when the air guide plates lap inside the lapping portion 212, the enclosing effect of the first air guide plate 610, the second air guide plate 620 and the mounting plate 210 is better, and the lapping is more stable, preventing the first air guide plate 610 from disengaging from the lapping portion 212 and the second air guide plate 620 from disengaging from the lapping portion 212 due to the action of air flow. It can be understood that the air guide plate assembly 600 further has a plurality of air guide plates provided between the first air guide plate 610 and the second air guide plate 620, and the middle air guide plate can be linked with the first air guide plate 610 or the second air guide plate 620 through a connecting rod to realize left and right air guiding.

[0080] In an embodiment, please refer to Figure 12, the swirl wind wheel 220 includes a first swirl wind wheel 221 and a second swirl wind wheel 222. The first swirl wind wheel 221 is fixedly connected to the installation through hole 211 of the installation plate 210; the second swirl wind wheel 222 is rotatably installed at the installation through hole 211, so that the blades of the second swirl wind wheel 222 and the blades of the first swirl wind wheel 221 are stacked or staggered with each other in the air passing direction of the installation through hole 211.

[0081] In this embodiment, the first swirl wind wheel 221 and the second swirl wind wheel 222 may specifically be axial flow wind wheels. The first swirl wind wheel 221 is fixedly connected to the installation through hole 211 of the installation plate 210. Then, the first swirl wind wheel 221 may be integrally formed with the installation plate 210, or may be fixed on the installation plate 210 by means of welding, bonding, crimping, etc. It should be noted that both the first swirl wind wheel 221 and the second swirl wind wheel 222 are installed at the installation through hole 211, and the two are stacked or staggered with each other in the air passing direction of the installation through hole 211. Then, the first swirl wind wheel 221 and the second swirl wind wheel 222 are arranged in sequence in the air passing direction of the installation through hole 211. The installation through hole 211 plays a role in guiding and leading the air flow. The number and size of the blades of the first swirl wind wheel may be the same as or different from those of the second swirl wind wheel. By fixing the first swirl wind wheel 221 at the installation through hole 211 and rotatably installing the second swirl wind wheel 222 at the installation through hole 211, on the one hand, the second swirl wind wheel 222 is continuously rotated to drive the air flow to blow out from the installation through hole 211, reduce the wind resistance and wind loss, effectively improve the air volume, and can flexibly control the strength of the blown air flow. On the other hand, the blades of the second swirl wind wheel 222 and the blades of the first swirl wind wheel 221 overlap or are misaligned with each other, so that the air flow passing through the installation through hole 211 is continuously cut, dispersed, shunted and stirred by the first swirl wind wheel 221 and the second swirl wind wheel 222, making the blown air more gentle, greatly improving the no-wind feeling effect, and making the divergence direction of the air flow controllable and adjustable.

[0082] The mounting plate 210 has a windward side and a leeward side, so the first swirl wind wheel 221 can be arranged on the windward side of the mounting plate 210, and the second swirl wind wheel 222 can be arranged on the leeward side of the mounting plate 210, or the first swirl wind wheel 221 can be arranged on the leeward side of the mounting plate 210, and the second swirl wind wheel 222 can be arranged on the windward side of the mounting plate 210. Preferably, the first swirl wind wheel 221 is arranged on the windward side of the mounting plate 210, and the second swirl wind wheel 222 is arranged on the leeward side of the mounting plate 210. In this way, the airflow passing through the mounting through hole 211 is first dispersed by the first swirl wind wheel 221 (static wind wheel) and then enters the second swirl wind wheel 222 (dynamic wind wheel), and the airflow is disturbed, cut and stirred again, thereby improving the windless effect. Furthermore, the second swirl wind wheel 222 is disposed on the leeward side of the mounting plate 210 , so that the user can directly observe the rotation of the second swirl wind wheel 222 , thereby improving the user's visual experience.

[0083] Specifically, the mounting plate 210 is arranged in an elongated strip shape, and a plurality of first swirl wind wheels 221 and second swirl wind wheels 222 are arranged. A plurality of mounting through holes 211 are arranged at intervals in the length direction of the mounting plate 210, and each mounting through hole 211 is correspondingly provided with a first swirl wind wheel 221 and a second swirl wind wheel 222, and the plurality of second swirl wind wheels 222 are transmission connected.

[0084] In this embodiment, each mounting through hole 211 is correspondingly provided with a first swirl wind wheel 221 and a second swirl wind wheel 222, that is, a static wind wheel and a dynamic wind wheel, so that each mounting through hole 211 can achieve windless air outlet. By providing multiple first swirl wind wheels 221 and multiple second swirl wind wheels 222, the air outlet of the entire wind dispersion assembly 200 is increased, wind resistance is reduced, and the overall windless effect is enhanced. The multiple second swirl wind wheels 222 are transmission-connected, so that only one driving device is provided to drive all the second swirl wind wheels 222 to rotate simultaneously, thereby simplifying the overall structure and facilitating control. Specifically, as Figure 6 and Figure 8 As shown, the wind dispersing assembly 200 also includes a driving motor, which is connected to one of the second swirl wind wheels 222 to rotate the plurality of second swirl wind wheels 222 in linkage. In one embodiment, the peripheral wall surface of each second swirl wind wheel 222 is provided with gear teeth, and the gear teeth of two adjacent second swirl wind wheels 222 are meshed with each other or indirectly meshed through a steering gear. The driving motor is specifically mounted on the mounting plate 210 to rotate with the wind dispersing assembly 200. When the wind dispersing assembly 200 rotates, there is a clearance space in the housing 100 to avoid the rotation of the driving motor.

[0085] The present invention also provides an air conditioner, which includes an outdoor unit of the air conditioner and a floor-standing indoor unit of the air conditioner that are connected through a refrigerant pipe. The specific structure of the floor-standing indoor unit of the air conditioner refers to the above-mentioned embodiments. Since this air conditioner adopts all the technical solutions of the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be elaborated one by one here.

[0086] 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 by using the content of the specification and drawings of the present invention under the inventive concept of the present invention, or any direct / indirect application in other related technical fields is included in the patent protection scope of the present invention.
