At the same time, the bottom case 1 has a mounting groove for installing the centrifugal fan 3 , the setting of the above mounting groove can further reduce the thickness of the air conditioner, making the air conditioner thinner. In the present application, the centrifugal fan 3 has a blade body plate 313 , the bottom shell 1 has an air duct bottom surface 181 located on the circumferential outer side of the installation groove, and the blade body plate 313 protrudes from the air duct bottom surface 181 . Centrifugal blower 3 wind can be blown outwards from above blade body plate 313 when blowing wind, and the wind after leaving blade body plate 313 can reach air duct bottom surface 181, and blade body plate 313 protrudes from air duct bottom surface 181 so that blade body plate 313 The resistance to the above-mentioned wind is smaller, thereby ensuring that the air conditioner can achieve a larger air output. It can be seen from the above content that the air conditioner of the present application effectively ensures the air output while solving the problem of thickness, so that the user experience is better.

In the first embodiment, the installation groove includes a bottom surface 1821 of the installation groove and a sidewall 1822 of the installation groove. The sidewall 1822 of the installation groove extends gradually from the bottom surface 1821 of the installation groove to the bottom surface 181 of the air duct. The above-mentioned structure makes the air outlet resistance smaller, thereby better ensuring the air outlet volume.

As shown in FIG. 17 , in the first embodiment, the busbar of the side wall 1822 of the installation groove and the bottom surface 1821 of the installation groove form an acute angle α. The above-mentioned structure is convenient for manufacturing, installation and maintenance, and at the same time, the above-mentioned structure can ensure that the airflow resistance is small.

The above acute included angle is preferably in the range of 40° to 50°. As shown in Figure 17, in this embodiment, the included angle α between the bus bar of the side wall 1822 of the installation groove and the bottom surface 1821 of the installation groove is 45°, which is simple to make, easy to realize, and beneficial to air flow The guidance forms a buffering effect.

As shown in FIG. 15 and FIG. 16 , in the first embodiment, the diameter of the bottom surface 1821 of the installation groove is larger than the outer diameter of the centrifugal fan 3 . This ensures that the centrifugal fan 3 can rotate smoothly in the space where it is located.

As shown in FIG. 15 , in Embodiment 1, there are two air ducts arranged side by side, and two centrifugal fans 3 corresponding to the air ducts are also provided. Two air ducts and corresponding centrifugal fans 3 are set. In this way, the air volume can be guaranteed on the one hand, and on the other hand, the occupied space of the air conditioner will not increase much. Of course, the number of air ducts and centrifugal fans 3 can be set to three or more as required.

As shown in Figure 1 and Figure 7, preferably, the fan is a centrifugal fan. The centrifugal fan includes: a guide ring 314; a blade body plate 313, which is spaced from the guide ring 314, and a protrusion protruding in the direction of the guide ring 314 is formed on the blade body plate 313, and a motor accommodation cavity is formed inside the protrusion; Fan blades are installed between the guide ring 314 and the blade body plate 313, and a plurality of fan blades are arranged along the circumferential direction of the protrusion.

The middle part of the blade body plate 313 forms a protrusion protruding from the guide ring 314, and the motor housing cavity with an opening on the surface of the blade body plate 313 facing away from the guide ring 314 is formed on the protrusion. The circumferential direction is evenly arranged, and the motor is placed between the guide ring 314 and the blade body plate 313, which reduces the thickness of the indoor unit of the air conditioner, and further reduces the space occupied by the air conditioner.

The specific structure and connection relationship of the upper air intake baffle 81 and the lower air intake baffle 82 will be described in detail below.

As shown in FIGS. 23 to 25 , specifically, the upper air intake baffle 81 and the lower air intake baffle 82 have the following working states: when both the upper air outlet 121 and the lower air outlet 122 are blowing air, the upper air inlet baffle 81 and the lower air inlet baffle 82 blocks the upper air inlet 61 and the lower air inlet 62 respectively; and/or when only the upper air outlet 121 is out of the wind, only the upper air inlet baffle 81 blocks the upper air inlet 61; and/or when only the lower air outlet 122 When the wind is out, only the lower air inlet baffle 82 blocks the lower air inlet 62.

What needs to be explained here is that while preventing the backflow of exhaust air, it is also necessary to ensure that the air conditioner has sufficient air intake, otherwise the heat exchange effect and energy efficiency of the air conditioner will also be reduced. Therefore, the air conditioner in the utility model only closes the upper air inlet baffle 81 and the lower air inlet baffle 82 simultaneously only when the upper air outlet 121 and the lower air outlet 122 are out of the air, otherwise it can be selectively closed and exhausted. The corresponding air intake baffle can be used. And when the upper air outlet 121 and the lower air outlet 122 are closed, it is necessary to rely on the side air inlet 63 to ensure the air intake.

The upper air intake baffle 81 and the lower air intake baffle 82 are reversibly arranged between the front panel 6 and the air duct cover 2 . Since a reversible upper air intake baffle 81 and a lower air intake baffle 82 are arranged between the front panel 6 and the air duct cover plate 2, by controlling the working state of the upper air intake baffle 81 and the lower air intake baffle 82, it is possible to Meet the anti-backflow requirements of different air outlet modes.

And when the upper air inlet baffle 81 is in the closed state and does not block the wind, the upper air inlet baffle 81 can be arranged close to the air duct cover plate 2 or the front panel 6, so as to keep the upper air inlet 61 out of the way, thereby ensuring the air conditioner Air intake reliability.

Similarly, the connection relationship between the lower air intake baffle 82 and the front panel 6 and/or the air duct cover 2 is similar to the connection relationship between the upper air intake baffle 81 and the front panel 6 and/or the air duct cover 2, here I won't go into details.

When the air inlet sealing structure is the air inlet sealing convex corrugation or the air inlet sealing step surface, when the upper air inlet baffle 81 is lapped on the air inlet sealing convex corrugation or the air inlet sealing step surface, it will not only play a sealing effect, but also It will play the role of limiting and stopping the upper air intake baffle 81, thereby effectively preventing the upper air intake baffle 81 from moving too far, and further improving the operation reliability of the upper air intake baffle 81.

In another specific embodiment, the first side of the upper air intake baffle 81 is pivotably connected to the front panel 6 , and the second side of the upper air intake baffle 81 can be turned toward the side of the air duct cover 2 .

Between the front panels 6 , an upper air intake baffle 81 and a lower air intake baffle 82 are reversibly disposed between the front panel 6 and the panel body 7 . At this time, since the panel body 7 is sandwiched between the air duct cover plate 2 and the front panel 6 , when the front panel 6 moves, the air inlet should be formed between the panel body 7 and the front panel 6 .

Preferably, the positions of the front panel 6 and the panel body 7 are adjustable. Since the positions of the front panel 6 and the panel body 7 are adjustable, the size of the air inlet can be adjusted by changing the distance between the front panel and the panel body 7, so that the air conditioner has the characteristic of adjustable air intake per unit time , thereby optimizing the heat transfer reliability of the air conditioner.

At this time, the first side of the upper air intake baffle 81 is pivotally connected to the front panel 6 and/or the panel body 7 , and the second side of the upper air intake baffle 81 is a free side. Since the upper air intake baffle 81 is pivotally connected to the front panel 6 and/or the panel body 7 , the operation reliability and storage reliability of the upper air intake baffle 81 are improved. And when the upper air intake baffle 81 is in the closed state and does not block the wind, the upper air intake baffle 81 can be arranged close to the panel body 7 or the front panel 6, so as to keep the upper air inlet 61 out of the way, thereby ensuring the air intake of the air conditioner. reliability.

Likewise, the connection relationship between the lower air intake baffle 82 and the front panel 6 and/or the panel body 7 is similar to the connection relationship between the upper air intake baffle 81 and the front panel 6 and/or the panel body 7, and will not be repeated here.

In this preferred embodiment, the first side of the upper air inlet baffle 81 is pivotably connected to the panel body 7, the surface of the front panel 6 facing the side of the panel body 7 has an air inlet sealing structure, and the upper air inlet baffle 81 The second side is sealingly matched with the air inlet sealing structure. Since the air inlet sealing structure is provided with the second side of the upper air inlet baffle 81 , the reliability of preventing backflow of the upper air inlet baffle 81 is ensured, thereby avoiding the backflow problem caused by air leakage. Certainly, the above-mentioned air inlet sealing structure may also be provided on the front panel 6 at a position corresponding to the lower air inlet baffle 82 .

Likewise, the above-mentioned air inlet sealing structure includes air inlet sealing ribs or air inlet sealing step surfaces.

Alternatively, the first side of the upper air intake baffle 81 is pivotally connected to the front panel 6 , and the second side of the upper air intake baffle 81 can be turned toward the panel body 7 .

As shown in Figure 24, in order to improve the storage reliability of the upper air intake baffle 81, the surface of the panel body 7 facing the front panel 6 in the utility model has a baffle accommodating groove 71, and the upper air intake baffle 81 can be accommodated in The baffle is accommodated in the groove 71. Since the panel body 7 is provided with a baffle accommodation groove 71 for accommodating the upper air inlet baffle 81, when the upper air inlet baffle 81 is retracted to avoid the upper air inlet 61, the upper air inlet 61 will be fully opened without blocking, thereby ensuring air conditioning. The air intake volume of the air conditioner ensures the energy efficiency of the air conditioner. Likewise, the above-mentioned baffle receiving groove 71 can also be used for accommodating the lower air intake baffle 82 .

The air conditioner in the utility model also includes the air intake grille 73 corresponding to the side air inlet 63 and the lower air inlet 62 respectively, and the air inlet grille 73 is connected with the drive mechanism 76 and/or the front panel 6 to follow the front panel 6 synchronized movement. Since the air inlet grille 73 is provided, the problem of accidental injury caused by accidental contact with the air inlet by human hands can be effectively avoided, thereby improving the safety of the air conditioner in use.

As shown in FIG. 22 , the air intake grill 73 is in the form of louvers.

In the second position, the first end of the air outlet baffle 9 and the groove wall of the rotating groove For airtight fit, the second end of the air outlet baffle 9 cooperates with the second side wall 11b of the air channel 11 to close the corresponding air outlet.

Preferably, a first escape groove for accommodating the wind baffle is formed on the first side wall 11a of the air duct 11 . In the first position, the air outlet baffle 9 is located in the first avoidance groove, and attached to the first side wall 11a, so as to avoid blocking the ventilation of the air outlet.

Preferably, a stop step surface 94 is provided on the second side wall 11 b of the air duct 11 , and the second end of the air outlet baffle 9 cooperates with the stop step surface 94 . In the second position, the second end of the air outlet baffle 9 abuts against the stop step surface 94, which increases the contact area and is beneficial to improve the sealing effect.

Preferably, the stop step surface 94 faces away from the corresponding air outlet 11 . The stop step surface 94 faces the side of the incoming wind, and when the corresponding air outlet is closed, the incoming wind drives the wind outlet baffle 9 to rotate toward the stop step surface 94, and the pressure of the incoming wind in the air duct 11 impels the movement of the air outlet baffle 9. The second end squeezes the stop step surface 94, which is beneficial to further improve the sealing effect.

Preferably, a second avoidance groove 95 is formed on the second side wall 11b of the air duct 11 to avoid the second end of the wind outlet baffle, and the groove wall of the second avoidance groove 95 facing away from the air outlet forms a stopper step Face 94.

Preferably, a gasket 96 is provided between the air outlet baffle 9 and the stopper step surface 94 . Further, the sealing effect is improved to prevent air leakage. The gasket 96 can be made of elastic materials such as sponge and rubber.

One of the two air outlets of the air duct 11 is formed at the upper part of the air conditioner, and the other is formed at the lower part of the air conditioner. In the cooling mode, if the user does not like the cold air blowing directly downward, the upward air outlet can be selected; in the heating mode, if the user prefers the hot air blowing directly, the downward air outlet can be selected. Customers can adjust which air outlet to let the air out according to their own needs.

The air channel 11 has a first side wall 11a and a second side wall 11b arranged oppositely, the first side wall 11a of the air channel 11 has a first inclined wind guide surface close to the air outlet and/or the second side wall 11b has a The second inclined air guiding surface of the tuyere.

Preferably, using the stepper motor 93 to drive the wind outlet baffle to rotate includes: the number of pulses output to the stepper motor 93 is greater than the calculated number of pulses required by the stepper motor.

The amount of rotation of the stepper motor is proportional to the number of pulses received, and the calculated number of pulses required by the stepper motor is calculated according to the preset required amount of rotation of the stepper motor 93 and based on its proportional relationship. pulse number, but the stepper motor often has a phenomenon that the actual rotation amount does not match the received pulse number. The number of pulses required by the motor to solve the above problems.

In this embodiment, the air conditioner also includes an anti-leakage structure. The structure and function of the anti-leakage structure will be described in detail below.

As shown in Figures 1 and 16, an air duct 11 is formed on the bottom shell 1, and the air duct cover plate 2 cooperates with the bottom shell 1 and is covered on the air duct 11. The diversion port 21; the centrifugal impeller 31 is arranged in the air duct 11 and corresponds to the diversion port 21, and there is a matching gap between the centrifugal impeller 31 and the air duct cover plate 2; the anti-leakage structure is arranged at the matching gap to reduce the air leakage in the fitting gap quantity.

Since there is an anti-leakage structure at the fitting gap, it can effectively block the fitting gap between the two, avoid or reduce the overflow of the incoming air from the fitting gap, ensure the reliability of the incoming air, and ensure that there can be enough A large amount of air is blown into the centrifugal impeller 31, thereby improving the energy efficiency and heat exchange effect of the air conditioner, and effectively reducing vibration and noise caused by air turbulence. Since the generation of condensation is fundamentally avoided, the safety threat of condensation to electrical components and potential safety hazards are eliminated, thereby ensuring the reliability of the air conditioner.

As shown in Figure 16, the anti-leakage structure in the utility model includes an annular windshield lip 312, which is arranged on the centrifugal impeller 31 and protrudes to the side of the air duct cover plate 2, and the annular windshield The inner diameter of the wind ledge 312 is larger than the diameter of the diversion port 21 . Since the centrifugal impeller 31 is provided with a windshield flange 312 protruding toward the side of the air duct cover plate 2, the matching gap is partially blocked, thereby reducing the width and the amount of air leakage of the air leakage gap, and then improving the effective performance of the air conditioner. Air intake volume and air intake reliability.

In the specific embodiment shown in FIG. 16 , the windshield flange 312 is located at the inner peripheral edge of the upper surface of the guide ring of the centrifugal impeller 31 . Since the windshielding lip 312 is located at the inner peripheral edge of the guide ring of the centrifugal impeller 31 , it can prevent the overflow of the incoming air at the first time, and optimize the effect of preventing air leakage.

Of course, the windshield lip 312 can also be arranged on the part between the inner ring and the outer ring of the centrifugal impeller 31, or directly arranged on the outer ring side of the centrifugal impeller 31, so that although it can also play the effect of preventing wind leakage, It is inevitable that part of the air volume will generate eddy currents in the space between the windshield flange 312 and the inner ring side of the centrifugal impeller 31, which will easily lead to air flow disorder and aggravate the vibration and noise of the air conditioner.

Preferably, the anti-leakage structure includes an anti-leakage groove 24 arranged on the air duct cover plate 2, and the protruding edge 312 of the windshield is embedded in the anti-leakage groove 24 and is clearance-fitted with the anti-leakage groove 24 (please refer to FIG. 16 ). Since the windshield protruding edge 312 is embedded in the anti-leakage groove 24, triple shielding is formed in the direction of air leakage, which prolongs the path of wind spillage and increases the tortuousness of the spillway path, so that the wind is not easy to flow from the matching The leakage at the gap ensures the reliability of air leakage prevention between the centrifugal impeller 31 and the air duct cover plate 2 .

Further, the wall surface of the anti-leakage groove 24 is an arc surface. Since the groove wall of the anti-leakage groove 24 is an arc surface, the wind can flow along the smooth arc guide surface when the wind overflows, thereby avoiding stress concentration or vortex, and effectively reducing the vibration and noise of the air conditioner.

The anti-leakage structure in the utility model comprises the anti-leakage protruding edge, and the anti-leakage protruding edge is the flange that the air guide port 21 of the air duct cover plate 2 stretches out to the air duct 11 side. Since the wind flows from the side of the air duct cover plate 2 to the centrifugal impeller 31, the leak-proof lip can effectively guide the wind, so that the wind can be smoothly poured into the centrifugal impeller 31 under the action of the leak-proof lip. Since the anti-leakage protruding edge protrudes from the air duct cover plate 2 to the centrifugal impeller 31 side, the matching gap is partially blocked, thereby reducing the width of the air leakage gap and the amount of air leakage, thereby improving the effective air intake and air intake of the air conditioner. wind reliability.

When the anti-leakage protruding edge is embedded in the inner side of the flow guide port 21 and further stretches into the centrifugal impeller 31 side, the opening direction of the air leakage gap will be changed at this time. It protrudes toward the inner ring side of the centrifugal impeller 31 so that the opening direction of the air leakage gap deviates from the air intake direction of the air guide port 21 . When the opening direction of the air leakage gap deviates from the air intake direction of the air guide port 21, the incoming wind from the air intake direction is directly blown into the centrifugal impeller 31, and it is difficult for the incoming wind to change its direction and enter the opening of the air leakage gap. Therefore, the air leakage between the centrifugal impeller 31 and the air duct cover plate 2 is effectively reduced, and the energy efficiency and heat exchange effect of the air conditioner are guaranteed.

In order to further improve the effect of preventing wind leakage, the anti-leakage convex edge is in the form of a ring, and the anti-leakage convex edge is located on the inner ring side of the wind-shielding convex edge 312 . Since the windshield protruding edge 312 and the anti-leakage protruding edge are provided at the same time, a double anti-leakage protection is formed, which further reduces the amount of air leakage. Because the anti-leakage convex edge has the effect of guiding the wind at the same time, when the anti-leakage convex edge is in contact with the air intake prior to the windshield convex edge 312, the anti-leakage effect can be optimized, so that the air duct cover plate 2 can play a certain role on the centrifugal impeller 31. The role of cladding and sealing.

Of course, it is also possible to arrange the windshielding convex edge 312 and the air leakage convex edge sequentially and at intervals along the air leakage direction. However, the air leakage prevention effect of the air conditioner arranged in this way is relatively poor.

In the utility model, there are a plurality of diversion openings 21, a plurality of anti-leakage structures, and a plurality of centrifugal impellers 31, and a plurality of centrifugal impellers 31, a plurality of diversion ports 21, and a plurality of anti-leakage structures are arranged in one-to-one correspondence with each other. . Since each diversion port 21 is corresponding to the above-mentioned anti-leakage structure, the overall air-leakage performance of the air conditioner is guaranteed. In the preferred embodiment shown in FIG. 10 , there are two diversion openings 21 , and the above-mentioned air leakage prevention structures are correspondingly provided at the two diversion openings 21 .

Preferably, there are multiple air channels 11 , the multiple air channels 11 are set independently of each other, and the multiple air channels 11 are set in one-to-one correspondence with the multiple centrifugal impellers 31 . Since the plurality of air ducts 11 are set independently of each other, it can effectively avoid the air flow disorder caused by the operation of the plurality of centrifugal impellers 31 and improve the air outlet reliability of the air conditioner.

In order to further improve the energy efficiency and control diversity of the air conditioner, there are multiple evaporators in the utility model, and the multiple evaporators are arranged in one-to-one correspondence with the multiple guide ports 21 . Due to the use of multiple evaporators, the quality of a single evaporator is reduced, thereby improving the installation convenience of the air conditioner, and when a single evaporator fails, only a single evaporator needs to be repaired and replaced, thereby reducing maintenance complexity and maintenance. cost and prolong the service life of the air conditioner. In addition, the operating power of the air conditioner can also be adjusted by controlling the operation of a single evaporator or part of the evaporators to meet different usage requirements.

Preferably, the evaporator is circular, and the shape of the evaporator is adapted to the shape of the guide port 21 . Since the shape of the evaporator is set to be compatible with the shape of the flow guide port 21 , each part of the evaporator can have the characteristics of consistent operation performance, and the heat exchange efficiency of each part of the evaporator can be uniform. In addition, the circular evaporator can effectively improve heat exchange efficiency, improve the energy efficiency level of the air conditioner, reduce power consumption, save materials, reduce cost waste, and reduce occupied space.

It should be noted that in order to ensure the uniformity of the refrigerant flow rate, pressure drop in the tube, and temperature distribution in each part of the evaporator, it is necessary to combine the flow rate of the refrigerant in different flow paths, the pressure drop in the tube, and the wind speed distribution on the surface of the evaporator. Design pipe diameter and sheet distance. High-efficiency heat exchange is achieved by adopting a combined design of different pipe diameters and different sheet distances. In addition, for the convenience of processing and manufacturing, the U tube of the evaporator is on the same side, and the other side of the tube is welded and other processes.

In this embodiment, the air duct 11 includes a first air duct 111 and a second air duct 112 extending from the upper side to the lower side. The arrangement form and function of the double air ducts with the first air duct 111 and the second air duct 112 will be described in detail below.

As shown in Figure 4 and Figure 24, the first air duct 111 and the second air duct 112 are arranged symmetrically, wherein the first air duct 111 has a first upper air outlet 1211 corresponding to the upper side and a first upper air outlet 1211 corresponding to the lower side. The lower air outlet 1221 , the second air duct 112 has a second upper air outlet 1212 corresponding to the lower side and a second lower air outlet 1222 corresponding to the lower side. Wherein, the first upper air outlet 1211 and the second upper air outlet 1212 form the upper air outlet 121 , and the first lower air outlet 1221 and the second lower air outlet 1222 form the lower air outlet 122 .

As shown in Figure 4, the first upper air outlet 1211 is provided with a first upper volute tongue 151, the first lower air outlet 1221 is provided with a first lower volute tongue 153, and the second upper air outlet 1212 is provided with a second upper air outlet. The volute tongue 152 and the second lower air outlet 1222 are provided with a second lower volute tongue 154 . Specifically, the first lower volute tongue 153 and the second lower volute tongue 154 respectively protrude toward a direction approaching each other, and the first upper volute tongue 151 and the second upper volute tongue 152 respectively protrude toward a direction away from each other. The air conditioner in this embodiment further includes a first centrifugal fan 3 a and a second centrifugal fan 3 b, wherein the first centrifugal fan 3 a is set in the first air duct 111 , and the second centrifugal fan 3 b is set in the second air duct 112 .

The arrangement direction of the first lower volute tongue 153 and the second lower volute tongue 154 determines the air outlet direction of the first air duct 111 at the first lower air outlet 1221 and the direction of the second air duct 112 at the second lower air outlet 1222 . The direction of the wind is converged. In this way, when the air conditioner is in the heating state, hot air can flow out from the first lower air outlet 1221 and the second lower air outlet 1222 of the air conditioner, and the hot air flowing out from the first air channel 111 and the second air channel 112 The hot air flowing out will be gathered together, thereby improving the heating effect and improving the heating performance of the air conditioner. At the same time, due to the slightly lower density of the hot air, the hot air slowly rises after being blown out from the first lower air outlet 1221 and the second lower air outlet 1222 of the air conditioner, which can form an overall indoor thermal cycle, and the temperature comfort is good. Therefore, the technical solution of this embodiment can solve the problem of slow heating speed of the air conditioner in the prior art.

In addition, when the air conditioner is cooling, cold air can be blown out from the first upper air outlet 1211 and the second upper air outlet 1212 . The cold wind blowing upwards can avoid directly blowing to the human body, and because the low-temperature gas has a high density, the cold wind will gradually sink to speed up the cooling speed. Therefore, the air conditioner in this embodiment has the characteristics of good cooling effect and high comfort for human body.

The air conditioner in this embodiment has four air outlets, namely the first upper air outlet 1211 , the first lower air outlet 1221 , the second upper air outlet 1212 and the second lower air outlet 1222 . As a preferred implementation manner, an air outlet baffle may be provided at each air outlet. In this way, the air outlet of the air outlet can be controlled according to the needs of the user. Specifically, when cooling or heating, four air outlets can be opened simultaneously to maximize the air output. Of course, from the perspective of comfort, the air outlet baffle can be used to close the first upper air outlet 1211 and the second upper air outlet 1212 during heating, so that the hot air is only blown out from the first lower air outlet 1221 and the second lower air outlet 1222 . During cooling, the air outlet baffle can be used to close the first lower air outlet 1221 and the second lower air outlet 1222 so that the hot air is only blown out from the first upper air outlet 1211 and the second upper air outlet 1212 .

As shown in Figure 4, in the technical solution of this embodiment, the first upper volute tongue 151 and the second upper volute tongue 152 are respectively arranged on the inner walls of the first upper air outlet 1211 and the second upper air outlet 1212 that are close to each other , the first lower volute tongue 153 and the second lower volute tongue 154 are respectively arranged on the inner walls of the first lower air outlet 1221 and the second lower air outlet 1222 which are far away from each other. Meanwhile, the distance between the first upper volute tongue 151 and the second upper volute tongue 152 is smaller than the distance between the first lower volute tongue 153 and the second lower volute tongue 154 . The above structure makes the first upper air outlet 1211 , the second upper air outlet 1212 , the first lower air outlet 1221 and the second lower air outlet 1222 larger in size, thereby effectively ensuring the air volume.

As shown in FIG. 6 , in the technical solution of this embodiment, the rotation direction of the blades of the first centrifugal fan 3 a and the rotation direction of the blades of the second centrifugal fan 3 b are opposite. Specifically, when the first centrifugal fan 3a and the second centrifugal fan 3b of the air conditioner work, the first centrifugal fan 3a and the second centrifugal fan 3b respectively drive the airflow and generate a certain impact force on the air conditioner. By setting the direction of rotation of the blades of the first centrifugal fan 3a and the direction of rotation of the blades of the second centrifugal fan 3b opposite, the impact force produced on the air conditioner when the first centrifugal fan 3a is working can be compared with that of the second centrifugal fan 3b when it is working. The impact force on the air conditioner is in the opposite direction. In this way, the force of the air conditioner can be uniform, the operation can be stable, and the noise can be effectively reduced at the same time.

Preferably, when the air conditioner is working, the rotation direction of the first centrifugal fan 3a is opposite to that of the second centrifugal fan 3b, so that the impact forces generated by the first centrifugal fan 3a and the second centrifugal fan 3b on the air conditioner cancel each other .

Specifically, by controlling the direction of the first upper sweeping mechanism 161 and the second upper sweeping mechanism 162, the first upper sweeping mechanism 161 and the second upper sweeping mechanism 162 selectively have the following working states:

The first upper sweeping mechanism 161 and the second upper sweeping mechanism 162 are guided to the same side;

Both the first upper sweeping mechanism 161 and the second upper sweeping mechanism 162 converge toward the inner side;

Both the first upper sweeping mechanism 161 and the second upper sweeping mechanism 162 are diffused and guided outward.

When the air conditioner is working, any of the above working states can be selected. This makes the air outlet direction more flexible to meet the temperature adjustment requirements in different environments.

Preferably, the first upper sweeping mechanism 161 and the second upper sweeping mechanism 162 are controlled separately, so that the above three working states are easier to realize.

Wherein, the first lower sweeping mechanism 163 is located at the first lower air outlet 1221 , and the second lower sweeping mechanism 164 is located at the second lower air outlet 1222 . The above-mentioned first lower air sweeping mechanism 163 and second lower air sweeping mechanism 164 are used to change the air outlet direction, so that the air outlet directions at the first lower air outlet 1221 and the second lower air outlet 1222 are more flexible.

Specifically, by controlling the direction of the first lower sweeping mechanism 163 and the second lower sweeping mechanism 164, the first lower sweeping mechanism 163 and the second lower sweeping mechanism 164 selectively have the following working states:

The first lower sweeping mechanism 163 and the second lower sweeping mechanism 164 are guided to the same side;
