[0002] Existing air conditioners adjust the room temperature by blowing cold or hot air out through the air outlet. Taking a floor-standing air conditioner as an example, the air outlet is usually set on the front of the air conditioner, that is, the side facing the user. An air guide louver is installed at the air outlet. The air outlet angle is controlled by the swing of the air guide louver, thereby controlling the air outlet range of the air conditioner. In addition, the size of the air outlet of the current air conditioner is already very large in proportion to the entire panel.

[0047] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0050] The present invention proposes an embodiment of an air conditioner. The existing air conditioner adjusts the room temperature by blowing cold air or hot air outward through the air outlet. Taking the floor-standing air conditioner indoor unit as an example, the air outlet is usually arranged on the front side of the air conditioner, that is, the side facing the user. An air guide louver is installed at the air outlet. The air outlet angle is controlled by the swing of the air guide louver, thereby controlling the air outlet range of the air conditioner. In addition, the size of the air outlet of the current air conditioner accounts for a very large proportion of the entire panel. Under the premise of ensuring that the volume of the whole machine does not increase, it is very difficult to further increase the size of the air outlet. However, affected by the size of the air outlet and the swing angle of the air guide louver structure, the air outlet range of the air conditioner is small, resulting in local overcooling and overheating problems in the room, affecting the user's experience.

[0051] See also Figures 1 to 8 In one embodiment of the present invention, the air conditioner 10 includes a shell 100, an air duct assembly 200 and a shutter assembly 400; the shell 100 has an air inlet 121, a first air outlet 111 and a second air outlet 112 extending in a vertical direction, and the first air outlet 111 and the second air outlet 112 are arranged at intervals; the air duct assembly 200 is arranged in the shell 100, and has a first air duct 201 and a second air duct 202 connected to the first air duct 201, a first air duct outlet 201a of the first air duct 201 is arranged corresponding to the first air outlet 111, and a second air duct outlet 202a of the second air duct 202 is arranged corresponding to the second air outlet 112; the shutter assembly 400 is arranged at the first air outlet 111 and / or the second air outlet 112.

[0052] Specifically, see Figure 3The housing 100 includes a front housing 110, a rear housing 120, a top cover 130 and a base 140. The front housing 110, the rear housing 120, the top cover 130 and the base 140 enclose an installation space for installing the internal components of the air conditioner 10 (such as a heat exchanger 600, a wind wheel 700, a driving device, etc.). The shape of the housing 100 can be rectangular, circular, polygonal, combined, or irregular, and can be selected and designed according to actual use requirements, and no specific limitation is made to this. The air inlet 121 is arranged on the rear housing 120, and the first air outlet 111 and the second air outlet 112 are arranged on the front housing 110. The air inlet 121, the first air outlet 111 and the second air outlet 112 all extend in the vertical direction, that is, extend along the length direction of the housing 100, which can ensure that the areas of the air inlet 121, the first air outlet 111 and the second air outlet 112 are large enough to increase the air intake and air outlet. The first air outlet 111 and the second air outlet 112 are arranged at intervals, and their opening directions can be both set to face the front, or can be set to face the two sides of the housing 100 respectively, and there is no specific limitation on this.

[0053] See also Figure 5 and Figure 8 The air duct assembly 200 is disposed in the housing 100 and is formed with two air ducts, wherein the air inlet side of the first air duct 201 is disposed corresponding to the air inlet 121, and the air outlet side of the first air duct 201 is disposed corresponding to the first air outlet 111, that is, the first air duct outlet 201a of the first air duct 201 is disposed corresponding to the first air outlet 111. The airflow enters the first air duct 201 through the air inlet 121, and flows to the first air outlet 111 through the first air duct 201 and is blown out under the action of the wind wheel 700. The second air duct 202 is connected to the first air duct 201. It should be noted that the second air duct 202 is a branch air duct of the first air duct 201. The air inlet side of the second air duct 202 is connected to the first air duct 201, and is connected to the air inlet 121 through the first air duct 201. The air outlet side of the second air duct 202 is arranged corresponding to the second air outlet 112, that is, the second air duct outlet 202a of the second air duct 202 is arranged corresponding to the second air outlet 112.

[0054] Two air outlets are arranged on the housing 100, and a first air duct 201 and a second air duct 202 are arranged on the air duct assembly 200 in the housing 100 corresponding to the two air outlets. The design of the two air outlets increases the overall area of ​​the air outlets compared to the traditional design of one air outlet, thereby increasing the air volume of the air conditioner 10. A shutter assembly 400 is arranged at the first air outlet 111 and / or the second air outlet 112, and the shutter assembly 400 is used to adjust the flow direction of the airflow passing through it, thereby adjusting the direction of the airflow blown out through the first air outlet 111 and the second air outlet 112. The preferred solution is to arrange the shutter assembly 400 at both the first air outlet 111 and the second air outlet 112, and adjust the flow direction of the airflow blown out of the first air outlet 111 and the second air outlet 112 at the same time. In detail, since the swing angle of the shutter assembly 400 is limited, when the number of air outlets is set to two, and the first air outlet 111 and the second air outlet 112 are arranged at intervals, the air flow can be blown out from the first air outlet 111 and the second air outlet 112 arranged at intervals, and the air outlet ranges of the first air outlet 111 and the second air outlet 112 can be adjusted at the same time through the shutter assembly 400. At this time, the air outlet range of the air conditioner 10 is the sum of the air outlet range of the first air outlet 111 and the air outlet range of the second air outlet 112, that is, the air outlet range of the air conditioner 10 is increased, so that the range of the air flow blowing into the room can be larger, and local overcooling or overheating will not occur.

[0055] It should be noted that the up and down direction mentioned in the present application refers to the direction perpendicular to the horizontal plane after the air conditioner 10 is placed on the horizontal ground, that is, the vertical direction, and the left and right direction refers to the width direction of the air conditioner 10 when it faces the user after it is installed indoors.

[0056] The technical solution of the present invention includes a shell 100, an air duct assembly 200 and a shutter assembly 400; the shell 100 has an air inlet 121, a first air outlet 111 and a second air outlet 112 extending in a vertical direction, and the first air outlet 111 and the second air outlet 112 are arranged at intervals; the air duct assembly 200 is arranged in the shell 100, and has a first air duct 201 and a second air duct 202 connected to the first air duct 201, a first air duct outlet 201a of the first air duct 201 is arranged corresponding to the first air outlet 111, and a second air duct outlet 202a of the second air duct 202 is arranged corresponding to the second air outlet 112; the shutter assembly 400 is arranged at the first air outlet 111 and / or the second air outlet 112. Since the swing angle of the shutter assembly 400 is limited, when the number of air outlets is set to two, and the first air outlet 111 and the second air outlet 112 are arranged at intervals, the air flow can be blown out from the first air outlet 111 and the second air outlet 112 arranged at intervals, and the air outlet ranges of the first air outlet 111 and the second air outlet 112 are adjusted at the same time through the shutter assembly 400. At this time, the air outlet range of the air conditioner 10 is the sum of the air outlet range of the first air outlet 111 and the air outlet range of the second air outlet 112, that is, the air outlet range of the air conditioner 10 is increased, so that the range of the air flow blowing into the room can be larger, and local overcooling or overheating will not occur.

[0057] See also Figure 5 and Figure 6 In one embodiment, the air duct assembly 200 includes a volute assembly 210 and an air outlet frame 220, the air outlet side of the volute assembly 210 is connected to the air inlet side of the air outlet frame 220, the volute assembly 210 includes a volute tongue 211 and a volute 212, and the second air duct 202 is arranged close to the volute 212.

[0058] Specifically, the volute assembly 210 and the air outlet frame 220 are connected together to form the first air duct 201 and the second air duct 202. As for the connection method of the volute assembly 210 and the air outlet frame 220, they can be connected in the form of snap-on connection or by screwing, or they can be connected together in other ways, and there is no specific limitation on this. The volute assembly 210 can use standard parts, and does not need to be designed and molded separately, which reduces the production cost. At the same time, the volute assembly 210 and the air outlet frame 220 are set as two independent components, which can ensure their respective performances and the processing accuracy of the volute assembly 210 and the air outlet frame 220, thereby ensuring that the air conditioner 10 will not generate large noise due to the impact of airflow in the volute assembly 210 and the air outlet frame 220 during operation.

[0059] On the flow path from the air inlet 121 to the first air outlet 111 and the second air outlet 112, the volute assembly 210 is located upstream of the air outlet frame 220, the air inlet side of the volute assembly 210 is arranged corresponding to the air inlet 121, the air outlet side of the volute assembly 210 is connected to the air inlet side of the air outlet frame 220, the volute assembly 210 forms a part of the first air duct 201, the air outlet frame 220 forms a part of the first air duct 201, the two parts of the first air duct 201 are connected to form a complete first air duct 201, and the second air duct 202 is formed on the air outlet frame 220. Further, the volute assembly 210 includes a volute tongue 211 and a volute 212, a part of the first air duct 201 is formed between the volute tongue 211 and the volute 212, and the volute 212 and the volute tongue 211 mainly play a role in guiding the airflow. The second air duct 202 is arranged close to the volute 212, that is, the extension direction of the second air duct 202 is different from the extension direction of the first air duct 201. The air duct structure of the part of the first air duct 201 and the second air duct 202 formed on the air outlet frame 220 is roughly designed in a "human" shape. Of course, in other embodiments, the part of the first air duct 201 and the second air duct 202 on the air outlet frame 220 can also be arranged in other shapes, as long as the first air outlet 111 corresponding to the first air duct outlet 201a and the second air outlet 112 corresponding to the second air duct outlet 202a are arranged at intervals when they are formed on the housing 100.

[0060] See also Figure 7 In one embodiment, a vertical plane perpendicular to the first air duct outlet 201a and a vertical plane perpendicular to the second air duct outlet 202a form an angle α, which satisfies 20°≤α≤150°.

[0061] Specifically, the vertical plane perpendicular to the first air duct outlet 201a may be a vertical plane perpendicular to the center line of the first air duct outlet 201a, and the vertical plane perpendicular to the second air duct outlet 202a may be a vertical plane perpendicular to the center line of the second air duct outlet 202a. When the two vertical planes intersect, an angle α is formed, so that the angle range of α satisfies 20°≤α≤150°, so as to ensure that there is enough distance between the first air duct outlet 201a and the second air duct outlet 202a, thereby ensuring that there is a certain distance between the first air outlet 111 corresponding to the first air duct outlet 201a and the second air outlet 112 corresponding to the second air duct outlet 202a, so that when the airflow is blown out from the first air outlet 111 and the second air outlet 112, the adjustable air outlet range of the shutter assembly 400 is large enough, thereby increasing the air outlet range of the air conditioner 10. Preferably, the angle range of α satisfies 60°≤α≤120°.

[0062] See also Figures 5 to 10In one embodiment, a guide assembly 300 is provided on the air inlet side of the air outlet frame 220, and the guide assembly 300 extends obliquely toward the direction of the second air duct 202. Specifically, after the airflow enters the air outlet frame 220, the airflow will be divided into two, flowing out from the first air duct 201 and the second air duct 202 respectively, and the extension direction of the first air duct 201 is substantially the same as the extension direction of the air duct end in the volute assembly 210, so most of the airflow flowing from the volute assembly 210 to the air outlet frame 220 will be blown out through the first air duct 201. In order to ensure the air volume of the second air duct 202, a guide assembly 300 is provided on the air inlet side of the air outlet frame 220, and the guide assembly 300 extends obliquely toward the direction of the second air duct 202, so as to guide the airflow flowing from the volute assembly 210 to the air outlet frame 220 to the second air duct 202 for air discharge, thereby ensuring the air volume of the second air duct 202. The flow guide component 300 is in a plate shape, which can be a straight plate or a curved plate.

[0063] Preferably, the flow guide assembly 300 is bent in the direction away from the volute tongue 211. With such a design, the smooth arc surface can have a better guiding effect on the airflow, and the airflow will not generate a large noise during the flow process.

[0064] See also Figure 6 In one embodiment, the guide assembly 300 includes a first guide vane 310 and a second guide vane 320, wherein the first guide vane 310 is located on a side of the second guide vane 320 away from the volute tongue 211; along the direction in which the second air duct 202 extends, the length of the second guide vane 320 is greater than the length of the first guide vane 310.

[0065] Specifically, the guide assembly 300 includes a first guide vane 310 and a second guide vane 320. The first guide vane 310 and the second guide vane 320 are both arranged in an arc-shaped sheet shape, and the first guide vane 310 is located on the side of the second guide vane 320 away from the volute tongue 211. The length of the second guide vane 320 is greater than the length of the first guide vane 310. The projection formed by the second guide vane 320 on the air inlet side of the second air duct 202 is greater than the projection formed by the first guide vane 310 on the air inlet side of the second air duct 202, that is, the second guide vane 320 at least blocks part of the air inlet of the second air duct 202. The first guide vane 310 is used to guide the airflow to one side of the second air duct 202, and the second guide vane 320 is used to guide the airflow to the other side of the second air duct 202. The two guide vanes can better guide the airflow and increase the air volume of the second air duct 202.

[0066] It is worth mentioning that the guide assembly 300 is integrally formed with the air outlet frame 220. This design can avoid the trouble of assembling the guide assembly 300 and the air outlet frame 220, further improving the production efficiency. At the same time, there is no need to set up a separate mold for producing the guide assembly 300, which reduces the design of the mold and reduces the cost. Of course, in other embodiments, the guide assembly 300 can also be used as a separate accessory and installed in the air outlet frame 220 later. Here, the installation method of the guide assembly 300 with the air outlet frame 220 is not specifically limited, for example, it can be clamped or screwed.

[0067] See also Figure 3 In one embodiment, the air conditioner 10 further includes a switch door 1000 , which is movably disposed at the first air outlet 111 and / or the second air outlet 112 to open or close the first air outlet 111 and / or the second air outlet 112 .

[0068] See also Figures 5 to 8 In one embodiment, the louver assembly 400 includes a horizontal louver assembly 410, which is arranged at the first air duct outlet 201a and / or the second air duct outlet 202a, and is rotatably connected to the air outlet frame 220 to adjust the direction of the airflow passing through the horizontal louver assembly 410.

[0069] Specifically, the horizontal louver assembly 410 can adjust the direction of the airflow blown out by the first air duct outlet 201a and / or the second air duct outlet 202a by swinging, thereby adjusting the air outlet range of the air conditioner 10. The horizontal louver assembly 410 is mainly used to adjust the air outlet range of the air conditioner 10 in the left and right directions. Under the drive of the driving device, it rotates relative to the air outlet frame 220 to achieve the adjustment of the airflow direction.

[0070] Furthermore, the horizontal louver assembly 410 includes a plurality of horizontal blades 411 arranged at intervals, and a plurality of first air outlet holes 411a are provided on the horizontal blades 411. The horizontal louver assembly 410 has an extended state and a closed state; when the horizontal louver assembly 410 is in the extended state, the air flow is blown out from the gap between any two adjacent horizontal blades 411; when the horizontal louver assembly 410 is in the closed state, the air flow is blown out from the plurality of first air outlet holes 411a.

[0071] Specifically, the horizontal blade 411 is arranged in a long strip-shaped plate shape, and a plurality of first air outlet holes 411a are arranged on the horizontal blade 411, and the plurality of first air outlet holes 411a are used to discharge air. The plurality of first air outlet holes 411a are arranged at intervals on the horizontal blade 411. It should be noted here that the first air outlet holes 411a are micro-holes for discharging air, not air holes with a larger area. The shape of the first air outlet holes 411a can be set to be circular, square, long strip or other special shapes. There is no specific limitation on the shape of the first air outlet holes 411a. The air passing area of ​​the first air outlet holes 411a is less than 30mm. 2 , to ensure that the airflow passing through it does not blow directly at the user.

[0072] The multiple horizontal blades 411 of the horizontal louver assembly 410 are arranged at intervals along the width direction of the first air outlet 111 and / or the second air outlet 112, and are rotatably connected to the air outlet frame 220, and are switched between the extended state and the closed state by the rotation of the multiple horizontal blades 411. Similarly, the horizontal blades 411 can also be opened from the closed state to a position at any angle and stop, and can be continuously rotated in a cycle relative to the air outlet frame 220 to adjust the direction of the airflow blown out in the left and right directions by the airflow passing through the horizontal louver assembly 410.

[0073] The horizontal louver assembly 410 has an extended state and a closed state. When the horizontal louver assembly 410 is in the extended state, the multiple horizontal blades 411 of the horizontal louver assembly 410 move to be roughly parallel to the flow direction of the airflow to minimize the resistance of the horizontal blades 411 to the airflow, so that the airflow can be blown out from the gap between any two adjacent horizontal blades 411; when the horizontal louver assembly 410 is in the closed state, the multiple horizontal blades 411 in the horizontal louver assembly 410 can be abutted together end to end in sequence to ensure that the airflow does not flow out from the gap between two adjacent horizontal blades 411, or the multiple horizontal blades 411 can be overlapped together end to end in sequence to ensure that the airflow does not flow out from the gap between two adjacent horizontal blades 411.

[0074] Specifically in this embodiment, multiple horizontal blades 411 are overlapped end to end in sequence to avoid the drawback that due to the dimensional error of the horizontal blades 411 in the production process, the airflow can still flow out from the gap between two adjacent horizontal blades 411 after the horizontal blades 411 are installed on the indoor unit of the air conditioner. Furthermore, the overlapping length between any two adjacent horizontal blades 411 does not exceed half of the width of the horizontal blades 411 itself, so as to ensure that there is enough space between the two adjacent horizontal blades 411 for the airflow to flow out, ensure the air output of the air conditioner 10 in the normal air outlet mode, and also avoid the installation trouble and high cost caused by too many horizontal blades 411.

[0075] When the horizontal louver assembly 410 is in the extended state, a strong airflow is blown out directly from the gap between any two adjacent horizontal blades 411, and the air conditioner 10 is in a normal air outlet mode with a large air volume. When the horizontal louver assembly 410 is in the closed state, the first air outlet 111 and / or the second air outlet 112 are blocked by the horizontal blades 411, and the airflow can only be blown out from the first air outlet 411a on the multiple horizontal blades 411, and the air conditioner 10 is in a windless air outlet mode.

[0076] Please continue reading Figures 5 to 8 , Fig.10 Furthermore, the louver assembly 400 also includes a vertical louver assembly 420 arranged upstream of the horizontal louver assembly 410, and the vertical louver assembly 420 includes a plurality of vertical blades 421 arranged at intervals, and the plurality of vertical blades 421 are rotatably connected to the air outlet frame 220 to adjust the direction of the airflow passing through the vertical louver assembly 420.

[0077] Specifically, the horizontal louver assembly 410 can be used to adjust the left-right direction of the airflow blown out from the first air duct outlet 201a and / or the second air duct outlet 202a, and the vertical louver assembly 420 can be used to adjust the up-down direction of the airflow blown out from the first air duct outlet 201a and / or the second air duct outlet 202a. The vertical louver assembly 420 includes a plurality of vertical blades 421 arranged along the length direction of the first air outlet 111 and / or the second air outlet 112, that is, the up-down direction. The plurality of vertical blades 421 are all rotatably connected to the air outlet frame 220 to adjust the direction of the airflow. A protective net 900 (see FIG. 1 ) can also be set between the horizontal louver assembly 410 and the vertical louver assembly 420. Figure 6 and Fig.10 ), to prevent the user's hand from reaching into the air duct and touching other components in the housing 100 to cause a safety hazard. Of course, in other embodiments, the vertical louver assembly 420 can also be arranged downstream of the horizontal vertical louver assembly 420.

[0078] See also Figure 6 , Fig.10 and Fig.11 In one embodiment, the air outlet frame 220 includes a first air guide wall 221, a second air guide wall 222 and a flow divider 223, the flow divider 223 is arranged between the first air guide wall 221 and the second air guide wall 222 to form the first air duct 201 and the second air duct 202, and the flow divider 223 is provided with an air outlet 223a; the air conditioner 10 also includes a panel 500, the panel 500 is arranged between the first air outlet 111 and the second air outlet 112, and the panel 500 is provided with a plurality of second air outlet holes 510 (see Fig.15 ), the plurality of second air outlet holes 510 are connected to the air outlet 223a.

[0079] Specifically, the first air guide wall 221 is a side wall of the first air duct 201 in the air outlet frame 220, and the second air guide wall 222 includes a first guide wall 222a and a second guide wall 222b, wherein a portion of the first air duct 201 is formed between the first guide wall 222a and the first air guide wall 221, and the second air duct 202 is formed between the second guide wall 222b and the diverter 223. The diverter 223 is also provided with an air outlet 223a, and the airflow in the first air duct 201 and the second air duct 202 can flow out of the air duct through the air outlet 223a. At the same time, a panel 500 is provided between the first air outlet 111 and the second air outlet 112, that is, the panel 500 is also located between the first air duct outlet 201a of the first air duct 201 and the second air duct outlet 202a of the second air duct 202. A plurality of second air outlet holes 510 are provided on the panel 500. The plurality of second air outlet holes 510 are through holes that penetrate the panel 500. The plurality of second air outlet holes 510 are all connected to the air outlet 223a. Therefore, the airflow flowing out of the air outlet 223a can be blown out through the plurality of second air outlet holes 510. The shape of the second air outlet 510 can be set to be circular, square, long strip or other special shapes. The shape of the second air outlet 510 is not specifically limited. The air flow area of ​​the second air outlet 510 is less than 30 mm. 2 , to ensure that the airflow passing through it does not blow directly at the user.

[0080] Therefore, when the air conditioner 10 is in the windless air outlet mode, the air flow can be discharged from the multiple first air outlet holes 411a on the horizontal louver assembly 410 and the second air outlet holes 510 located on the panel 500 at the same time. The air outlet area of ​​the air conditioner 10 in the windless state is greatly increased, so that the windless capacity is correspondingly improved, thereby increasing the cooling capacity of the air conditioner 10 in the windless state.

[0081] See also Figure 6 , Fig.10 and Fig.11 Further, the diverter 223 includes a first diverter portion 223b and a second diverter portion 223c, the first diverter portion 223b is used to guide the airflow of the first air duct 201, the second diverter portion 223c is used to guide the airflow of the second air duct 202, and the air outlet 223a is arranged on the first diverter portion 223b and the second diverter portion 223c.

[0082] Specifically, a first air duct 201 is formed between the first diverter portion 223b and the first air guide wall 221, and a second air duct 202 is formed between the second diverter portion 223c and the second guide wall 222b. In order to avoid the airflow flowing out through the air outlet 223a only flowing out from the first air duct 201 or the second air duct 202, affecting the air output of the first air outlet 111 or the second air outlet 112, air outlets 223a are optionally provided on the first diverter portion 223b and the second diverter portion 223c, so that part of the airflow in the first air duct 201 and the second air duct 202 flows out through the air outlet 223a and is discharged through the panel 500.

[0083] See also Fig.10 In one embodiment, the number of the air outlets 223a is set to be multiple, and the multiple air outlets 223a are arranged at intervals along the length direction of the diverter 223. Specifically, the number of the air outlets 223a can be set to be multiple, and the multiple air outlets 223a are arranged at intervals along the length direction of the diverter 223 to increase the amount of air flowing through the air outlets 223a, thereby increasing the air output of the panel 500. Of course, in other embodiments, the air outlet 223a can also be set to a long strip extending along the length direction of the diverter 223.

[0084] See also Fig.12 In one embodiment, the width of the air outlet 223a is D1, which satisfies 10mm≤D1≤30mm. Specifically, in order to prevent the width of the air outlet 223a from being too wide and affecting the air volume of the first air outlet 111 and the second air outlet 112, and to ensure that the air conditioner 10 does not leak too much air in a windless state, the width of the air outlet 223a is limited to between 10mm and 30mm.

[0085] See also Fig.13In one embodiment, the shortest distance between the extension line of the side wall of the air outlet 223a close to the air inlet side of the air outlet frame 220 and the side wall of the air outlet 223a away from the air inlet side of the air outlet frame 220 is D2, satisfying D2≥3mm. Specifically, in order to ensure that the wind does not escape from the air outlet 223a as much as possible when the air conditioner 10 is in the normal air outlet mode, a height difference is designed for the opposite side walls of the air outlet 223a along the air outlet direction of the air conditioner 10, that is, along the air outlet direction of the air conditioner 10, the extension line of the side wall of the air outlet 223a close to the air inlet side of the air outlet frame 220 is lower than the side wall of the air outlet 223a away from the air inlet side of the air outlet frame 220 by a distance D2. In this way, when the air conditioner 10 is supplying air normally, the wind will directly pass over the air outlet 223a under the action of the airflow, and be blown out from the first air outlet 111 and the second air outlet 112 on both sides of the shell 100, thereby effectively reducing the wind escaped from the air outlet 223a. When the air conditioner 10 is in the windless air outlet mode, the horizontal louver assembly 410 is in a closed state, and the horizontal louver assembly 410 blocks the airflow, and part of the airflow in the first air duct 201 and the second air duct 202 is blown back in the opposite direction of the normal air outlet direction of the first air duct 201 and the second air duct 202 to the air outlet 223a and discharged through the plurality of second air outlet holes 510 on the panel 500. When D2 is greater than or equal to 3 mm, a better effect is achieved.

[0086] See also Figure 5 or Figure 8 In one embodiment, the width of the panel 500 is not less than 150 mm. Specifically, the panel 500 is disposed between the first air outlet 111 and the second air outlet 112. In order to realize the large-angle surrounding air supply of the first air outlet 111 and the second air outlet 112, the width of the panel 500 between the first air outlet 111 and the second air outlet 112 is set to be not less than 150 mm.

[0087] In another embodiment, a plurality of third air outlet holes (not shown in the figure) are provided on the vertical blades 421, and when the vertical louver assembly 420 blocks the first air duct 201 and / or the second air duct 202, the air flow is blown out through the plurality of third air outlet holes. Specifically, the air conditioner 10 of the present invention can also achieve a windless air outlet mode by providing third air outlet holes on the plurality of vertical blades 421 of the vertical louver assembly 420, and by blocking the first air duct 201 and / or the second air duct 202 through the vertical louver assembly 420, so that the air flow is blown out from the plurality of third air outlet holes on the vertical blades 421, thereby achieving windless air outlet of the air conditioner 10.

[0088] See also Fig.14In one embodiment, the first air outlet hole 411a and / or the second air outlet hole 510 and / or the third air outlet hole are long holes, and the long holes are arranged horizontally, vertically, in a combination of horizontal and vertical arrangements, inclined or in a curved shape.

[0089] Specifically, the first air outlet 411a, the second air outlet 510 and the third air outlet can be designed in the shape of a long strip, and their extension direction can also be horizontal, vertical or inclined, or a combination of multiple extension directions, or they can be extended in a curved or wavy shape, or in other extension modes. They can be arranged at regular intervals or at irregular intervals, and there is no specific restriction on this. The air flow area of ​​the first air outlet 411a, the second air outlet 510 and the third air outlet is less than 30mm 2 , to ensure that the airflow passing through it will not blow directly on the user, thereby achieving windless air outlet of the air conditioner 10.

[0090] Please continue reading Fig.14 In one embodiment, the first air outlet 411a and / or the second air outlet 510 and / or the third air outlet is a circular hole, an elliptical hole, a square hole or a polygonal hole; a plurality of the first air outlet 411a and / or the second air outlet 510 are arranged in an array. Specifically, the shapes of the first air outlet 411a, the second air outlet 510 and the third air outlet can also be set to circular holes, elliptical holes, square holes or polygonal holes, or other special-shaped holes, without specific restrictions. The arrangement can be arranged at regular intervals or at irregular intervals, without specific restrictions. The wind passing area of ​​the first air outlet 411a, the second air outlet 510 and the third air outlet is less than 30mm 2 , to ensure that the airflow passing through it will not blow directly on the user, thereby achieving windless air outlet of the air conditioner 10.

[0091] It should be emphasized that the extension direction, shape, and arrangement of the first air outlet 411a, and / or the second air outlet 510, and / or the third air outlet, as long as the airflow passing therethrough can be a breeze that does not blow directly on the user, that is, the windless feeling function can be achieved, are all within the protection scope of the present invention and are not specifically limited thereto.

[0092] In one embodiment, the width of the first air outlet 111 and / or the second air outlet 112 is not less than 50 mm. Specifically, in order to improve the cooling capacity of the air conditioner 10 in the windless air outlet mode, the width of the first air outlet 111 and / or the second air outlet 112 is set to be not less than 50 mm, preferably, the width of the first air outlet 111 and the second air outlet 112 are both set to be not less than 50 mm.

[0093] Furthermore, in order to ensure that the first air outlet 111 and the second air outlet 112 provided on the housing 100 are basically symmetrical and to ensure the symmetrical beauty of the appearance, the difference between the width of the first air outlet 111 and the width of the second air outlet 112 can be optionally set to be no greater than 20 mm.

[0094] See also Figure 5 or Figure 8 In one embodiment, the air conditioner 10 further includes a heat exchanger 600 and a wind wheel 700. The heat exchanger 600 is arranged corresponding to the air inlet 121 and is semi-enclosed on the outside of the wind wheel 700. The air outlet side of the wind wheel 700 is arranged corresponding to the air inlet side of the air outlet frame 220.

[0095] Specifically, the heat exchanger 600 is used to perform heat exchange on the airflow passing through it, and the wind wheel 700 applies power to the airflow flowing in from the air inlet 121, and passes through the air outlet frame 220 and flows out from the air outlet.
