That is to say, the third air outlet A3 and the front air outlet a2 expand the air outlet range in front of the air conditioner together, so as to further improve the front air outlet capacity of the air conditioner, and the air conditioner can blow air outwards from the front air outlet a2 of the front panel A8 and can blow air upwards from the third air outlet A3 at the top of the air conditioner when blowing air outwards, thereby further improving the air outlet effect. It should be noted that the front side of the present invention refers to the side of the air conditioner facing the user. The third outlet A3 can be defined by the uncovered part of the opening a7 of the main body a 6.
In some embodiments, as shown in fig. 3 and 4, the first air outlet a21 is communicated with the air inlet a1, and a first fan D is disposed in the first air duct a4 formed by the communication; the second air outlet A22 is communicated with the air inlet A1, and a second fan E is arranged in a second air duct A5 formed by the communication; the first fan D and the second fan E are respectively and independently controlled. The first fan D is configured to drive air from the air inlet a1 to the front air outlet a2, i.e., air from the air inlet a1 can be driven by the first fan D and directed out of the front air outlet a2, and the second fan E is configured to drive air from the air inlet a1 to the front air outlet a2 or the uncovered portion of the opening a 7.
In some embodiments, as shown in fig. 5, the upper edge portion of the front panel A8 has a predetermined gap a71 therebetween with the upper edge portion of the opening a 7. That is, the predetermined gap a71 defines another air outlet except the front air outlet a2 at the front end of the indoor unit 1000 of the air conditioner, and the other air outlet is located at the top of the air conditioner, and the third air outlet A3 and the front air outlet a2 located below the third air outlet a are used for supplying air together, so that the air conditioner can blow air outwards from the front air outlet a2 of the front panel A8 and can blow air upwards from the third air outlet A3 of the air conditioner when blowing air outwards, thereby expanding the air outlet range of the air conditioner, further improving the front air outlet capability of the air conditioner, and further enhancing the air outlet effect. It should be noted that the front side of the present invention refers to the side of the air conditioner facing the user.
Specifically, the lower edge portion of the front panel A8 may be attached to the lower edge portion of the opening a7, the left edge portion of the front panel A8 may be attached to the left edge portion of the opening a7, and the right edge portion of the front panel A8 may be attached to the right edge portion of the opening a 7. Therefore, the edge parts are mutually covered, no gap is reserved between the edge parts, and the air after heat exchange in the air conditioner can be only sent out from the front air outlet A2 and the third air outlet A3.
Further, as shown in fig. 5, the predetermined gap a71 may range from 40mm to 150mm in a front view of the cabinet a. It can be understood that the preset gap a71 is too small to facilitate the quick sending of the air after heat exchange in the air conditioner, which is easy to cause the accumulation of the air in the casing and the increase of the internal pressure, and has the problem of poor heat dissipation effect; on the other hand, if the predetermined gap a71 is too large, the wind after heat exchange is sent out from the other wind outlet at any time, so that the wind flow is not uniform, and the wind circulation in the room is not facilitated, therefore, the range of the predetermined gap a71 is set to be 40 mm-150 mm, and the effect of the wind flowing through the predetermined gap a71 in the area range can be ensured to be better.
In a specific embodiment, the size of the predetermined gap a71 may be 40mm, and at this time, the size difference between the top air outlet formed by the predetermined gap a71 and the air outlet on the front panel A8 is large, in this state, the air after heat exchange of the air conditioner is mainly sent out from the front air outlet a2, and is sent out from the top air outlet formed by the predetermined gap a71 as an auxiliary, so as to improve the air outlet effect of the air conditioner.
In a particular embodiment, the predetermined gap a71 may be 66mm in size. It can be understood that, not only can the better effect of sending out the air in the air conditioner be guaranteed, but also the circulation of the air in the room can be guaranteed, and the air outlet effect of the preset gap A71 is optimal at the moment.
In a specific embodiment, the size of the predetermined gap a71 may also be 150mm, and it can be understood that, at this time, the size difference between the top air outlet formed by the predetermined gap a71 and the front air outlet a2 on the front panel A8 is the smallest, in this state, the air after heat exchange of the air conditioner mainly comes from the two air outlets, and the two air outlets have substantially the same function, and together play a role in adjusting the outward air outlet effect of the air conditioner.
In some embodiments, as shown in fig. 1-5, the height of the front panel A8 may range from 1300mm to 1800 mm. Therefore, the height of the front air outlet A2 is proper to the height of a human body, the air sent out by the front air outlet A2 can be directly blown to the area where the human body is located, meanwhile, the structure of the third air outlet A3 is combined, the height of the third air outlet A3 is higher than that of the area where the human body is located, the air sent out by the third air outlet A3 is blown to the upper portion of the human body, then the airflow naturally sinks to the area where the human body is located, the human body cannot feel the wind or feels weaker, and therefore the comfort of a user is improved.
The ratio range between the height of the front panel A8 and the height of the air outlet net cover L is: 2-5, the ratio range between the area of the front panel A8 and the area of the air outlet net cover L is 3-6. The following are alternative examples:
alternatively, in some specific embodiments, the height of the front panel a820 may be 1300 mm. At this time, if the height of the front panel a820 is the smallest, the height of the opposite outlet 21 is small, and the air is relatively concentrated at a low height in the room when the air is discharged.
In a particular embodiment, the height of the front panel a820 may also be 1800 mm. At this time, if the height of the front panel a820 is the largest, the height of the opposite outlet 21 is large, and the air is relatively concentrated at a high height in the room during air conditioning.
In a specific embodiment, a ratio between the height of the front panel A8 and the height of the air outlet cover L may be 3.75, and a ratio between the area of the front panel A8 and the area of the air outlet cover L may be 4.5. Thereby being more beneficial to production and manufacture.
In a specific embodiment, the height of the front panel A8 is 1582mm, and the height of the main body A6 is 1879mm, so that the height ratio of the front panel A8 to the main body A6 is appropriate, and the front panel A is more beautiful in appearance.
In a specific embodiment, the distance between the bottom of the air outlet cover L and the bottom of the main body a6 is 1234mm, and the position of the front air outlet a2 can be determined by the position of the air outlet cover L. By adopting the mode, the height positions of the air outlet net cover L and the front air outlet A2 are most suitable, and the outward air outlet of the air conditioner is facilitated. In addition, when the air outlet net cover L is located at the height position, the air conditioner can avoid direct blowing to children when air is exhausted outwards, and cold or other diseases caused by direct blowing of the children in a cold air state are avoided.
In some embodiments, as shown in fig. 5, the dimension range of the air outlet cover L in the left-right direction may be: 350 mm-450 mm. The air outlet net cover L is connected to the front air outlet A2. When the size of the air outlet cover L is too small, the air outlet capability of the front air outlet a2 is obstructed, and the size of the air outlet cover L is more suitable in the size range in consideration of the size of the actual air conditioner. The air outlet mesh enclosure L with the size is convenient to manufacture and beneficial to production.
In a specific embodiment, the dimension of the air outlet net cover L in the left-right direction may be 350mm, and at this time, the dimension of the air outlet net cover L is the smallest, so that the air outlet capability of the front air outlet a2 is limited to a certain extent, so as to achieve the stable air outlet effect of the front air outlet a 2.
In a specific embodiment, the dimension of the air outlet net cover L in the left-right direction may be 382 mm. Therefore, the air outlet net cover L is appropriate in size and good in air supply effect.
In a specific embodiment, the dimension of the air outlet mesh enclosure L in the left-right direction may also be 450mm, and at this time, the dimension of the air outlet mesh enclosure L is the largest, and the flow rate of the air blown out from the front air outlet a2 is the largest, which is beneficial to further expanding the air outlet range of the air conditioner.
More specifically, as shown in fig. 5, when the dimension of the air outlet net cover L in the left-right direction is 382mm, the dimension of the air outlet net cover L in the up-down direction at this time is 392 mm. So that the area of the air outlet net cover L under the size can completely cover the front air outlet a 2.
In some alternative embodiments, as shown in fig. 6, the air outlet net cover L is provided with a plurality of uniformly arranged equilateral triangle meshes L1, and the side length of each mesh L1 ranges from 1mm to 20 mm. Therefore, the meshes L1 are made into equilateral triangle shape, which can play better decorative role and make the whole more beautiful. Secondly, mesh L1 is too little to be favorable to sending out of wind, and mesh L1 is too big to play certain windage effect, consequently sets up mesh L1's length of side scope to 1mm ~ 20mm, and the play of existing being favorable to sending out of wind can also play certain windage effect simultaneously like this, improves the air-out effect.
In a specific embodiment, the side length of the mesh L1 of the equilateral triangle on the air outlet cover L may be 1 mm. That is to say, mesh L1 size is minimum and compact on air outlet net cover L this moment, is difficult for observing air conditioner inner structure, has more the decorative effect on the appearance, more seems pleasing to the eye.
In a specific embodiment, the side length of the mesh L1 of the equilateral triangle on the air outlet cover L may also be 20 mm. That is to say, mesh L1 size is the biggest and loose on air outlet net cover L this moment, is favorable to the air conditioner air-out.
In a particular embodiment, the plurality of mesh openings L1 may have a side length of 13.5 mm. Therefore, the production and the manufacture are facilitated, and the cost is reduced.
In other embodiments, the shape of the mesh L1 is not limited to the shape of an equilateral triangle, but may be configured in other shapes, for example, the mesh L1 may also be a diamond, a rectangle, a circle or an ellipse (not shown), and also when the mesh L1 is a diamond, the side length of the diamond may be 13.5mm, so as to ensure that the mesh L1 has a good ventilation effect.
Of course, in other embodiments of the present invention, the shape of the mesh L1 may be various, and various patterns may be combined. For example, the air outlet net cover L may be formed of a plurality of concentric circular regions (not shown), the shape of the mesh L1 of the central concentric circular region is an equilateral triangle, the mesh L1 of the outer concentric circular region is a rhombus, and the mesh L1 of the outer concentric circular region is a direction, so that the overall appearance is more beautiful. For another example, the air outlet net cover L may be formed by a plurality of square ring regions (not shown), the mesh L1 of the innermost square ring region is rhombic, the mesh L1 of the outer square ring region is square, and the mesh L1 of the outermost square ring region is equilateral triangle, which can also improve the appearance.
In some alternative embodiments, as shown in fig. 6, the ratio of the sum of the areas of the plurality of meshes L1 to the area of the air outlet is in the range of 0.5 to 0.8. Through the mode, namely the whole air outlet mesh enclosure L can play a certain wind resistance effect, when the air subjected to heat exchange in the indoor unit 1000 of the air conditioner is sent out from the front air outlet a2, the air firstly acts on the air outlet mesh enclosure L, and is diffused and blown out from the meshes L1 after being hindered by a certain amount, so that the air subjected to heat exchange is prevented from being intensively blown out outwards, and a part of the air conditioned air still directly passes through the meshes L1 and is blown out from the meshes L3526 after acting on the air outlet mesh enclosure L, but the wind sensation of the human body is weakened to a certain extent at the moment, so that the comfortable degree is better, and the other part of the air is diffused along the circumferential direction of the air outlet mesh enclosure L and is blown out from the nearest meshes L1, so that the meshes L1 at other positions on the air outlet mesh enclosure L all pass through, and the effect of uniform air blowing is achieved, and the wind sensation of the air.

Specifically, the front panel A8 has a dimension in the front-rear direction of 70 mm. It is understood that 70mm is the optimum dimension of the front panel A8 in the front-back direction, and it is also understood that the depth of the front panel A8 in the front-back direction is 70mm, which is beneficial for the front panel A8 to cling and wrap on the main body a6, so as to combine the two.

In some embodiments, as shown in fig. 8, the wind guide blade 100 includes: a plurality of transverse vanes 110. The plurality of horizontal guide vanes 110 are respectively rotatably arranged in the air outlet frame F and positioned on the front side of the flow guide ring G, the plurality of horizontal guide vanes 110 are arranged at intervals in the vertical direction, at least one part of the plurality of horizontal guide vanes 110 is provided with a groove 1101 for accommodating the flow guide ring G, and the parts of the horizontal guide vanes 110 positioned on the two sides of the groove 1101 extend backwards to the rear side of the front end of the flow guide ring G. It will be appreciated that the grooves 1101 may be arranged such that the portions of the transverse vanes 110 on either side of the grooves 1101 extend rearwardly to the rear of the forward end of the flow guiding ring G. Thus, the distance between the transverse guide vane 110 and the first fan D is shortened, the air volume of the supplied air is increased, the air supply range of the transverse guide vane 110 can be expanded, and the air supply effect of the transverse guide vane 110 is improved.

The driving device 160 can drive the transverse vane N10 to make the transverse vane 110 rotate relatively on the left side plate F2 and the right side plate F3, so that the connecting rod 120 connected with the transverse vane 110 moves along with the transverse vane 110, and the other transverse vanes 110 connected with the connecting rod 120 rotate along with the connecting rod 120, and the rotating transverse vane 110 can guide the flow direction of the air in the first air outlet a21 and the second air outlet a 22.
In some optional embodiments, as shown in fig. 9 to 11, a plurality of hooks 1201 are provided on the connecting rod 120, and the plurality of transverse vanes 110 are respectively coupled to the plurality of hooks 1201 in a one-to-one correspondence manner, wherein a hanging column 1103 is provided on the transverse vane 110, and the hanging column 1103 is coupled to the hooks 1201. That is, the link 120 is connected to the lateral guide vane 110 by the engagement of the hanging post 1103 and the hook 1201, and the link 120 and the lateral guide vane 110 can move together by the friction force between the hanging post 1103 and the hook 1201.
Specifically, as shown in fig. 13, a mounting groove 1102 which is open backwards is formed in the transverse guide vane 110, and the hanging columns 1103 are disposed in the mounting groove 1102, wherein the hanging columns 1103 are hooked by the hooks 1201 from top to bottom or from bottom to top, and the hanging columns 1103 on each transverse guide vane 110 correspond to each other in the up-down direction. Therefore, the hook 1201 can hook the hanging column 1103 from top to bottom or from bottom to top, so that the transverse guide vane 110 is connected with the connecting rod 120, and as the transverse guide vane 110 is installed on the left side plate F2 and the right side plate F3 of the air outlet frame F, the left side plate F2 and the right side plate F3 can limit the transverse guide vane 110, so that the connecting rod 120 connected with the transverse guide vane 110 can be stably installed on the transverse guide vane 110.
Further, as shown in fig. 12, each hook 1201 includes a laterally extending portion 1201A and a longitudinally extending portion 1201B, the laterally extending portion 1201A and the longitudinally extending portion 1201B are perpendicularly connected to each other, and the laterally extending portion 1201A is connected to the link 120. The cross-section of the lateral extension 1201A is semicircular. It will be appreciated that the lateral extension 1201A may provide a mating surface for the hanging post 1103, and that upon assembly, there is a degree of friction between the lateral extension 1201A and the hanging post 1103 that allows the hanging post 1103 to rotate together on the hook 1201. For example, when the driving device 160 drives at least one of the plurality of transverse vanes 110, the frictional force between the hanging post 1103 on the blade N10 and the arc surface can drive the connecting rod 120 to rotate together, and further drive the other blades N10 on the hook 1201 to rotate together. When the driving device 160 directly drives the connecting rod 120, the friction force between the hanging column 1103 and the lateral extension portion 1201A directly drives the lateral guide vane 110 to rotate along with the connecting rod 120, thereby guiding the wind.
The hanging post 1103 in this embodiment may penetrate the longitudinally extending portion 1201B to conform to the outer surface of the transversely extending portion 1201A, so that the blade N10 does not need to be assembled to the hook 1201 by pressing, thereby reducing deformation of the hook 1201 as much as possible, further increasing structural strength of the hook 1201, and improving assembly efficiency of the blade N10 and the hook 1201.
Alternatively, as shown in fig. 10, one of both ends of the length of the link 120 is provided with a hook 1201, and the other of both ends of the length of the link 120 is provided with a lateral stopper 1202 perpendicular to the length of the link 120. It will be appreciated that a hook 1201 provided at one of the two ends of the length of the link 120 may mount the transverse vane 110. Thus, when the lateral guide vane 110 is mounted to the hook 1201, the provision of a lateral stop 1202 perpendicular to the length of the link 120 at the other of the two ends of the length of the link 120 may provide a stop for clamping, thereby facilitating the mounting of the lateral guide vane 110.

When the longitudinal guide vane 130 is in the up-and-down wind sweeping state, the wind sweeping connecting rod 170 reciprocates up and down under the action of the wind guide driving mechanism 150. And is not particularly limited herein.
Specifically, as shown in fig. 14 and 15, the wind sweeping link 170 includes: the wind-driven wind-sweeping connecting rod comprises a driving wind-sweeping connecting rod 1701 and a driven wind-sweeping connecting rod 170, wherein a sliding groove 1704 is formed in the driving wind-sweeping connecting rod 1701, a first guide rod 140 in sliding fit with the sliding groove 1704 is arranged at one end of a first wind guide blade 1301, the other end of the first wind guide blade 1301 is connected with the driven wind-sweeping connecting rod 170, a second guide rod in sliding fit with the sliding groove 1704 is arranged at the end part, close to the driving wind-sweeping connecting rod 1701, of a second wind guide blade 1302, and the end part, close to the driven wind-sweeping connecting rod 170, of the second wind guide blade 1302.

That is, when the wind guide driving mechanism 150 drives the active wind sweeping link 1701 to reciprocate left and right, the active wind sweeping link 1701 drives the first wind guide blade 1301 and the first group of wind guide blades 1302A to move simultaneously, the first wind guide blade 1301 on the active wind sweeping link 1701 transmits the acting force to the driven wind sweeping link 170 connected thereto, the driven wind sweeping link 170 follows the movement, and the driven wind sweeping link 170 further drives the second group of wind guide blades 1302B to move. Therefore, the utility model discloses a first wind blade 1301 and second wind blade 1302 synchronism are high, and swing angle control is accurate, and wind-guiding actuating mechanism 150 sets up simply, and occupation arrangement space is few.
Specifically, as shown in fig. 9 and 15, when the active air sweeping link 1701 reciprocates, the first guide rod 140 slides from one end of the slide slot 1704 to the other end, the first air guiding blade 1301 rotates by 90 degrees, the second guide rod slides from one end of the slide slot 1704 to the other end, and the second air guiding blade 1302 rotates by 90 degrees. Here, after the longitudinal guide vane 130 rotates by 90 degrees, it can be switched to a first motion state and a second motion state, so that the air guiding mechanism J has the first motion state and the second motion state, and the air guiding mechanism J is convertible between the first motion state and the second motion state.
Alternatively, as shown in fig. 9 and 15, the slide slot 1704 is formed in a half-moon shape or an arc shape, which is smooth when the first and second guide bars 140 and 1704 slide in the slide slot 1704, and the guide of the slide slot 1704 is facilitated.

Therefore, when the wind sweeping motor 1501 rotates, the driving wind sweeping connecting rod 1701 is driven to reciprocate through the matching of the transmission gear 1502 and the transmission gear 1702, and the driving is stable.

That is, first air guide blade 1301 and second air guide blade 1302 are driven by dynamic wind sweeping link 1701, respectively, and directly change the motion state. In this case, the drive transmission of the wind guide driving mechanism 150 should be kept as synchronous as possible, so that the motion states of all the first wind guide blades 1301 and all the second wind guide blades 1302 are kept consistent.
In some alternative embodiments, as shown in fig. 8 and 9, the second wind directing blades 1302 sequentially increase in length in a direction away from the axis of the guide ring G. Therefore, the second wind-guiding blade 1302 is more suitable for the shape of the space between the wind-guiding ring G and the wind-outlet frame F, so that the second wind-guiding blade 1302 is convenient to arrange and has good movement effect after arrangement.
Optionally, as shown in fig. 8 and fig. 9, the longitudinal guide vane 130 has a first motion state and a second motion state, and the longitudinal guide vane 130 is convertible between the first motion state and the second motion state, wherein in the first motion state, the first air guide blade 1301 and the second air guide blade 1302 are parallel to the plane where the air outlet side of the guide ring G is located, and the gap between the first air guide blade 1301 and the second air guide blade 1302 is 1-2 mm; that is, the blade surfaces of the first wind guiding blade 1301 and the second wind guiding blade 1302 partition the air guiding ring G and the air outlet frame F along the air outlet direction, so that the air guiding amount or the air speed of the second air outlet a22 is greatly reduced. At this time, the first air guiding blade 1301 and the second air guiding blade 1302 form a side wall, and the air flowing direction of the second air outlet a22 in the air outlet frame F is changed. When the gap between the first air guide blade 1301 and the second air guide blade 1302 is greater than 2mm, the first air guide blade 1301 and the second air guide blade 1302 cannot form a side wall in the first motion state, and when the gap between the first air guide blade 1301 and the second air guide blade 1302 is less than 1mm, the first air guide blade 1301 and the second air guide blade 1302 are easily overlapped or interfere with and collide with other connectors in the first motion state.

That is, the blade surfaces of the first wind guiding blade 1301 and the second wind guiding blade 1302 are parallel to the wind outlet direction of the guiding ring G, so that the wind in the second wind outlet a22 can smoothly pass through between the guiding ring G and the wind outlet frame F, and if there is wind in the guiding ring G2, the wind volume of the whole longitudinal guide vane 130 along the wind outlet side of the guiding ring G is large at this time. In the second motion state, when the distance between the first air guiding blade 1301 and the second air guiding blade 1302 is less than 4mm, the arranged air guiding blades 10031 are too dense, which is inconvenient for linkage and installation; when the blade surface distance between the first air guiding blade 1301 and the second air guiding blade 1302 is greater than 6mm, the air guiding blades 100 are arranged too sparsely, and the flexibility is poor when the air outlet is adjusted.

It can be understood that, in the first movement state, when the projection areas of the first air guiding blade 1301 and the second air guiding blade 1302 in the air outlet frame F account for the difference between the cross section of the air outlet frame F and the cross section of the air guiding ring G to be less than 80%, the side wall effect formed by the first air guiding blade 1301 and the second air guiding blade 1302 in the first movement state is weakened, and when the air between the air guiding ring G and the air outlet frame F is designed to be the upper air outlet, the air volume of the air led out upwards is insufficient. When the projection areas of the first air guiding blade 1301 and the second air guiding blade 1302 in the air outlet frame F account for a difference between the cross section of the air outlet frame F and the cross section of the air guiding ring G to be greater than 90%, the first air guiding blade 1301 and the second air guiding blade 1302 are prone to overlapping and interfering in a first motion state.
In the second motion state, the projection areas of the first air guiding blade 1301 and the second air guiding blade 1302 in the air outlet frame F account for 5% -10% of the difference between the cross section of the air outlet frame F and the cross section of the air guiding ring G. It can be understood that, when the projection areas of the first air guiding blade 1301 and the second air guiding blade 1302 in the air outlet frame F account for the difference between the cross section of the air outlet frame F and the cross section of the air guiding ring G to be less than 5%, the thicknesses of the first air guiding blade 1301 and the second air guiding blade 1302 are too thin, and the rigidity and the strength are insufficient, so that the first air guiding blade 1301 and the second air guiding blade 1302 are easy to deform. When the projection areas of the first air guiding blade 1301 and the second air guiding blade 1302 in the air outlet frame F account for the difference between the cross section of the air outlet frame F and the cross section of the air guiding ring G to be greater than 10%, the first air guiding blade 1301 and the second air guiding blade 1302 generate a large wind resistance to wind between the air guiding ring G and the air outlet frame F in the second motion state, and air outlet is not smooth enough.
Optionally, as shown in fig. 8, both the front and the rear of the flow guiding ring G are open, and an axial flow fan or a cross flow fan is arranged in the flow guiding ring G. The air sucked by the axial flow fan or the cross flow fan is guided out towards the first air outlet A21 along the guide ring G.

Namely, on one hand, the left side plate F2 and the right side plate F3 are arranged at a distance in the left-right direction to form a flow passage for the air flow, which plays a role of guiding the flow. On the other hand, through left side board F2 and right side board F3, air-out frame F can be fixed on casing A steadily, plays spacing, fixed effect.
The air guide ring G is arranged in the air outlet frame F, a first sub air duct A51 extending up and down is defined between the left side wall of the air guide ring G and the left side plate F2, and a second sub air duct A52 extending up and down is defined between the right side wall of the air guide ring G and the right side plate F3. Therefore, air entering from the air inlet A1 can flow through the inside of the guide ring G and also can flow through the first sub-air duct A51 and the second sub-air duct A52 which are formed by the left side plate F3 and the right side plate F3 and the guide ring G and extend up and down, and a plurality of drainage branches are arranged, so that the air supply range is expanded, and the air supply effect is improved. The first sub-air duct A51 extending from top to bottom is defined between the left side wall of the guide ring G and the left side plate F2, and the second sub-air duct A52 extending from top to bottom is defined between the right side wall of the guide ring G and the right side plate F3, so that left and right side plates F3 and the guide ring G are formed with left and right branches flowing from top to bottom, the air supply range is favorably enlarged, the air supply effect is improved, and the user experience is improved.
In some embodiments, as shown in fig. 16 and 17, the front air outlet a2 is located at the front side of the flow guiding ring G, and the inner cavity of the flow guiding ring G is respectively communicated with the air inlet a1 and the front air outlet a2, so as to ensure that a part of the air sent by the air inlet a1 can enter the front air outlet a2 through the drainage of the inner cavity of the flow guiding ring G.
Specifically, as shown in fig. 16 and 17, the air conditioning indoor unit 1000 further includes: the first fan D is arranged in the guide ring G to drive airflow to flow from the air inlet A1 to the front air outlet A2.

It is understood that the air from the air inlet a1 can be sucked by the first fan D and guided out of the front air outlet a 2. The air from the air inlet a1 can also be sucked by the second fan E, and drives the air to flow through the first sub-air duct a51 and the second sub-air duct a52 and then towards the front air outlet a2 and the third air outlet A3. Therefore, air in the air inlet A1 can be guided by a plurality of fans, the air flowing range is enlarged, and the air supply effect of the indoor unit 1000 of the air conditioner is improved.

Specifically, as shown in fig. 17, the width of the air outlet end of the volute I is greater than the width of the flow guiding ring G. That is, a part of the air sent out from the outlet I2 of the volute I can pass through the baffle of the deflector G, so as to flow through the first sub-air duct a51 and the second sub-air duct a52 in a split manner, and because the width of the air outlet end of the volute I is greater than the width of the deflector G, the air sent out from the outlet I2 of the volute I can also directly flow into the first sub-air duct a51 and the second sub-air duct a52, which is beneficial to the rapid passing of air flow, so as to improve the air outlet efficiency of the indoor unit 1000 of the air conditioner.
