[0052] Figure 4The thin arrow indicates the airflow direction in the third air duct 405, the thick arrow indicates the airflow direction in the first air duct 10, the thick arrow indicates the air outlet direction of the guide tube 303, and the width direction of the shell 1 indicates the left and right direction.

[0053] Figure 5 The middle arrow indicates the direction of airflow within the second air duct 20.

[0054] This disclosure provides an air conditioner, which includes a main refrigerant circuit and a fan. The main refrigerant circuit includes a compressor, an indoor heat exchanger, an outdoor heat exchanger, and a throttling device connected through a refrigerant pipeline. The fan includes an indoor fan and an outdoor fan.

[0055] like Figures 1 to 27 As shown, this embodiment of the present disclosure provides an indoor unit of an air conditioner. The indoor unit includes a housing 1, a first air supply assembly and a guide tube 30. The housing 1 defines a first air duct 10 having a first air outlet 103. The first air supply assembly includes a first fan 101 and a first heat exchanger, located within the first air duct 10. The indoor heat exchanger includes the first heat exchanger, and the indoor fan includes the first fan 101.

[0056] The guide tube 30 is located on at least one side of the first air duct 10; the housing 1 includes a side wall 40 located between the guide tube 30 and the first air duct 10; wherein the guide tube 30 and the side wall 40 together define a third air duct 405, the third air duct 405 having a third air inlet 406 and a third air outlet 407 both communicating with the outside, the third air outlet 407 being located on at least one side of the first air outlet 103, so that the airflows from the first air outlet 103 and the third air outlet 407 can mix, for example, the airflows from the first air outlet 103... When the airflow direction of the first air outlet 103 and the third air outlet 407 intersects or coincides with that of the third air outlet 407, the airflows from the first air outlet 103 and the third air outlet 407 can mix. When the first air outlet 103 is discharging air, a negative pressure is formed at the third air outlet 407 to guide the ambient air from the third air inlet 406 through the third air duct 405 to the third air outlet 407. The ambient air mixes with the airflow from the first air outlet 103 before flowing out.

[0057] In the embodiment, the airflow in the first air duct 10 exchanges heat with the first heat exchanger, and the airflow flowing out of the first air outlet 103 is heat-exchanged air. Since the guide cylinder 30 and the side wall 40 are located on at least one side of the first air duct 10, the third air duct 405 is located on at least one side of the first air duct 10, and the airflows flowing out of the third air outlet 407 and the first air outlet 103 can be mixed. When the first air outlet 103 discharges air, a negative pressure is formed at the third air outlet 407, and the ambient air flows out of the third air outlet 407 through the third air inlet 406 and the third air duct 405. After the heat-exchanged air flowing out of the first air outlet 103 and the ambient air flowing out of the third air outlet 407 are mixed, uniform air is formed, and then flows to the indoor. The uniform air is relatively soft, and the user feels more comfortable when the uniform air blows on the user, thereby improving the comfort experience of the user.

[0058] Optionally, the side wall 40 is matched with the outer wall surface of the guide cylinder 30.

[0059] In the embodiment, the side wall 40 is matched with the outer wall surface of the guide cylinder 30, which means that the side wall 40 has the same or similar shape as the outer wall surface of the guide cylinder 30. The matching of the side wall 40 and the outer wall surface of the guide cylinder 30 makes the flow area of the third air duct 405 more uniform and the guide path of the third air duct 405 longer. In this way, the airflow flowing in the third air duct 405 can avoid excessive resistance, or the ambient air supply can be ensured due to the relatively short guide path of the third air duct 405. In this way, the air volume of the ambient air flowing out of the third air outlet 407 can be ensured, and the mixing effect of the mixed air of the air conditioner can be improved.

[0060] Optionally, the outer wall surface of the guide cylinder 30 includes an annular wall surface, and the side wall 40 is arc-shaped and has an opening facing the guide cylinder 30.

[0061] In the embodiment, the outer wall surface of the guide cylinder 30 is annular, and the side wall 40 is arc-shaped and has an opening facing the guide cylinder 30, so that the outer wall surface of the guide cylinder 30 is matched with the side wall 40. In this way, the airflow flowing in the third air duct 405 is more uniform, and the flow rate is more stable.

[0062] Optionally, when the outer wall surface of the guide cylinder 30 has other shapes, the side wall 40 also has corresponding shapes. For example, when the outer wall surface of the guide cylinder 30 is straight, the side wall 40 is also straight; when the outer wall surface of the guide cylinder 30 is curved, the side wall 40 is also curved.

[0063] Optionally, the third air outlet 407 is matched with the first air outlet 103 to realize that the airflows flowing out of the third air outlet 407 and the first air outlet 103 can be mixed, thereby realizing air mixing.

[0064] In the embodiment, the matching of the third air outlet 407 and the first air outlet 103 means that the third air outlet 407 and the first air outlet 103 have the same or similar extension direction, shape, size, and the like.

[0065] In the embodiment, the third air outlet 407 matches the first air outlet 103, the mixing area of the air flow from the first air outlet 103 and the third air outlet 407 is increased, and then the air flow from the third air outlet 407 and the first air outlet 103 can be fully mixed.

[0066] Optionally, as shown in Figure 2 and Figure 4 , the shell 1 includes a front shell 11 and a rear shell 12, and the first air duct 10 is further provided with a first air inlet 104; wherein the first air inlet 104 is arranged on the rear shell 12, the first air outlet 103 is arranged on the front shell 11, and the air flow in the first air duct 10 flows in the direction from the rear to the front.

[0067] In the embodiment, the air flow in the first air duct 10 flows in the direction from the rear to the front, which can reduce the flow path of the air flow in the first air duct 10, reduce the loss of the air flow, and ensure the temperature of the air flow from the first air outlet 103. Moreover, the space occupied by the first air fan 101 and the first air fan 101 in the air conditioner is saved, so that the structure of the air conditioner is more compact.

[0068] Optionally, as shown in Figure 25 , the first air fan 101 includes a cross-flow fan, the cross-flow fan is vertically placed, and the first air outlet 103 is arranged along the length direction of the cross-flow fan.

[0069] In the embodiment, the first air fan 101 adopts the cross-flow fan, so that the air flow from the first air outlet 103 can reach a very long distance.

[0070] Optionally, in the case that the first air fan 101 adopts the cross-flow fan, the first air outlet 103 matches the length direction of the cross-flow fan, that is, the first air outlet 103 extends along the length direction of the cross-flow fan, and the size of the first air outlet 103 is the same as or similar to the length of the cross-flow fan.

[0071] Optionally, the third air outlet 407 extends along the length direction of the cross-flow fan and matches the first air outlet 103.

[0072] Optionally, the flow guide cylinder 30 matches the first air outlet 103, for example, the length of the flow guide cylinder 30 is the same as or similar to the length of the first air outlet 103, the shape of the flow guide cylinder 30 is the same as or similar to the shape of the first air outlet 103, and the length of the side wall 40 is the same as or similar to the length of the first air outlet 103.

[0073] In this way, the shape, extension direction and size of the third air outlet 407 and the first air outlet 103 are the same or similar. Then the mixing area of the air flow from the third air outlet 407 and the first air outlet 103 can be increased, and the mixing effect of the mixed air can be increased.

[0074] Optionally, the first fan 101 can also be other fans, such as centrifugal fan, axial fan, etc.

[0075] Optionally, the first air duct 10 can also be arranged in a vertical direction, a width direction or an inclined direction, and the extension direction of the first air duct 10 can be arranged according to the shape of the shell 1.

[0076] Optionally, the first heat exchanger and the first fan 101 are arranged in sequence along the flow direction of the airflow in the first air duct 10, or the first fan 101 and the first heat exchanger are arranged in sequence.

[0077] Optionally, the first heat exchanger is arranged at the first air inlet 104, so that the airflow flows into the indoor after being heated.

[0078] Optionally, as shown in Figure 4 The side wall 40 is connected between the front shell 11 and the rear shell 12, and the airflow in the third air duct 405 flows in the direction from the rear to the front.

[0079] In this embodiment, the side wall 40 is connected between the front shell 11 and the rear shell 12, so that the side wall 40 can be stably connected to the air conditioner. Moreover, the airflow in the third air duct 405 can also flow in the direction from the rear to the front, fully utilizing the space between the first air duct 10 and the flow guide cylinder 30. The air inlet amount of the third air inlet 406 is ensured, while the resistance of the airflow flowing in the third air duct 405 is reduced. The third air duct 405 flows in the direction from the rear to the front, the distance is short, the loss of airflow flowing is small, and the gravity and other resistances are not overcome, so that the airflow can flow smoothly into the third air outlet 407.

[0080] Optionally, as shown in Figure 1 The number of the flow guide cylinder 30 is multiple, and the multiple flow guide cylinders 30 include the first flow guide cylinder 301 and the second flow guide cylinder 302, and the first flow guide cylinder 301 and the second flow guide cylinder 302 are respectively located on both sides of the first air duct 10; wherein the number of the side wall 40 is the same as and corresponds to the number of the flow guide cylinder 30.

[0081] The flow guide cylinder 30 and the side wall 40 are respectively located on both sides of the first air duct 10, and it can be understood that the number of the third air duct 405 is multiple, and the number of the third air duct 405 is the same as and corresponds to the number of the flow guide cylinder 30, and the multiple third air ducts 405 include the first sub-air duct and the second sub-air duct, and the first sub-air duct and the second sub-air duct are respectively located on both sides of the first air duct 10.

[0082] In the embodiment, the first sub-air duct and the second sub-air duct are respectively located at two sides of the first air duct 10, and the outflow amount of the environmental wind is increased. When the first air outlet 103 discharges air, the first sub-air duct and the second sub-air duct at two sides can both flow out the environmental wind, and then the heat exchange air of the first air outlet 103 is mixed, thereby improving the mixing effect of the mixed air of the air conditioner.

[0083] Optionally, as shown in Figure 2 and Figure 4 , the flow area of the first air inlet 104 is greater than the flow area of the first air outlet 103.

[0084] In the embodiment, the flow area of the first air inlet 104 is greater than the flow area of the first air outlet 103, and the air inflow amount of the first air duct 10 is increased to ensure the air outflow amount of the first air duct 10. The first air outlet 103 has a small area, so that the first flow guide cylinder 301 and the second flow guide cylinder 302 can be arranged at two sides of the first air outlet 103, thereby avoiding that the size of the air conditioner is too large.

[0085] In the case that the first air fan 101 is a cross-flow fan, the axial direction of the cross-flow fan is relatively long, and the radial dimension is relatively small. The flow area of the first air inlet 104 is greater than the flow area of the first air outlet 103, and the first heat exchanger and the cross-flow fan are sequentially arranged along the flow direction of the airflow in the first air duct 10, so that the space of the shell 1 can be efficiently utilized, the first flow guide cylinder 301 and the second flow guide cylinder 302 at two sides of the first air outlet 103 can be arranged with sufficient space, and the size of the indoor unit of the air conditioner is not additionally increased.

[0086] Optionally, the first air inlet 104 is arc-shaped to increase the flow area of the first air inlet 104.

[0087] Optionally, the first heat exchanger is matched with the first air inlet 104, so that the airflow flows through the first heat exchanger and then flows into the room. Specifically, the first heat exchanger is arc-shaped and covers the first air inlet 104. So that the airflow flows through the first heat exchanger and then flows to the first air fan 101.

[0089] In the embodiment, the structure layout of the first air duct 10, the guide cylinder 30 and the side wall 40 is reasonable, the size of the air conditioner is not additionally increased, and the application range of the air conditioner is improved. In the direction from the rear to the front, the cross-sectional area of the containing cavity gradually decreases, so that there is enough space in the containing cavity to place the first fan 101 and the first heat exchanger, and the volute 2011 of the first fan 101, and the cross-sectional area of the containing cavity close to the front shell 11 gradually decreases, which can avoid the guide cylinder 30 and ensure that the guide cylinder 30 has enough space to be installed. In this way, the size of the air conditioner is not additionally increased, and the function of the air conditioner can be increased.

[0090] Optionally, the flow area of the third air outlet 407 is greater than the flow area of the third air inlet 406.

[0091] In the embodiment, the flow area of the third air outlet 407 is large, so that the space for mixing the airflow at the third air outlet 407 and the airflow out of the first air outlet 103 is increased, and then the mixing time of the environmental wind and the heat exchange wind is increased, and the mixing effect of the mixed wind is improved.

[0092] Optionally, the side wall 40 includes a body and a guide plate, the guide plate is connected to the wall surface of the body facing the guide cylinder 30, the guide plate includes a first guide plate and a second guide plate connected in sequence, and the first guide plate and the second guide plate are arranged in sequence along the flow direction of the airflow in the third air duct 405, wherein the first guide plate matches the outer wall surface of the guide cylinder 30, and the second guide plate is inclined toward the first air outlet 103 along the flow direction of the airflow in the third air duct 405.

[0093] In the embodiment, the second guide plate is inclined toward the first air outlet 103 along the flow direction of the airflow in the third air duct 405, the outer wall surface of the guide cylinder 30 includes an annular wall surface, and then the flow area of the part of the third air duct 405 defined by the guide cylinder 30 and the second guide plate gradually increases. Finally, the flow area of the third air outlet 407 is greater than the flow area of the third air inlet 406.

[0126] In the embodiment, the air flow in the second air duct 20 flows in a direction from below to above, which can be understood as that the second fan 201 is located at the lower part of the shell 1, fully utilizing the space in the shell 1, without increasing the size of the air conditioner, saving the space occupied by the air conditioner.

[0138] Moreover, the flow area of the wind tunnel 60 gradually increases along the flow direction of the air flow, so that the area of the end surface of the wind tunnel 60 facing the flow guide cylinder 30 is large, and more second air outlets 203 can be provided, thereby providing sufficient second air outlets 203 connected with the plurality of flow guide cylinders 30.

[0139] In another specific embodiment, the second heat exchanger 202 can also be inverted V-shaped, and the flow area of the wind tunnel 60 gradually decreases along the flow direction of the air flow in the wind tunnel 60.

[0152] In this embodiment, the third wall segment 2017 increases the space around the first mounting portion 20141, so that when the purification device 2018 has a large size, it can be partially located on the third wall segment 2017. This arrangement makes the volute 2011 applicable to purification devices 2018 of various sizes, and reduces the requirement for the manufacturing precision of the purification device 2018 and the first mounting portion 20141.

The distance between each first mounting portion 20141 and the corresponding second mounting portion 20142 gradually increases, which means that the distance between each first mounting portion 20141 and the corresponding second mounting portion 20142 gradually increases. This arrangement allows the purification device 2018 mounted on the first mounting portion 20141 and the corresponding second mounting portion 20142 to have a larger size, which can increase the area of the airflow to be purified and improve the purification efficiency.

In this way, the purification device 2018 is convenient to take, and replacement and maintenance of the purification device 2018 are facilitated.

[0169] For example, when the volute 2011 is arranged in the up-down direction, the mounting portions 2014 all extend in the horizontal direction, and the purification device 2018 can be placed on the mounting portion 2014, thereby realizing installation of the purification device 2018.

[0170] Optionally, the plurality of purification devices 2018 installed in the volute 2011 can be the same or different. For example, when the airflow blown by the second fan 201 contains a high content of a certain harmful substance, two or more purification devices 2018 for purifying the substance can be arranged. If the airflow blown by the second fan 201 contains multiple harmful substances, multiple purification devices 2018 for purifying the harmful substances can be arranged.

[0174] Optionally, the support rod 601 extends in the up-down direction, the upper end of the support rod 601 is flush with the upper surface of the air tunnel 60, and the height of the lower end of the support rod 601 is less than or equal to the bottom of the volute 2011.

[0175] Through the arrangement of the support rod 601 in this embodiment, the length of the support rod 601 connecting the outer wall surface of the air tunnel 60 and the outer wall surface of the volute 2011 is increased, and the connection stability of the air tunnel 60 and the second fan 201 is further increased.

[0176] Optionally, in the case where the flow area of the air tunnel 60 gradually increases along the flow direction of the airflow, the outer wall surface of the air tunnel 60 is recessed inward to form a mounting groove, and the support rod 601 is located in the mounting groove, so as to facilitate the support rod 601 to extend in the up-down direction.

[0177] Optionally, the support rod 601 is detachably connected with the outer wall surface of the air tunnel 60, such as a bolt, a buckle, or the like. Optionally, the support rod 601 is detachably connected with the outer surface of the volute 2011, such as a bolt, a buckle, or the like.

[0178] In the case where the flow area of the air tunnel 60 gradually increases along the flow direction of the airflow, the outer surface of the volute 2011 is protruded outward to form a connecting plate 403, so as to be connected with the support rod 601.

[0179] Optionally, the number of support rods 601 is multiple, and the multiple support rods 601 can further increase the connection stability of the second fan 201 and the air tunnel 60.

[0180] In one specific embodiment, the plurality of support rods 601 include a first support rod and a second support rod, which are arranged along the width direction of the air conditioner. This arrangement ensures that the support rods 601 do not obstruct the airflow from the first fan 101.

[0181] Optionally, the housing 1 also includes an outer cover, inside which the second fan 201 and the wind tunnel 60 are located. The outer cover protects the second fan 201 and the second heat exchanger 202, preventing dust from the external environment from entering the second fan 201 or the second heat exchanger 202. At the same time, the outer cover also enhances the aesthetic appearance of the air conditioner.

[0182] Optionally, the outer cover includes a front shell 11 and a rear shell 12, with the second air inlet 204 located on the rear shell 12 to facilitate air intake of the second air duct 20.

[0183] Optionally, the outer cover also includes a limiting part. When the support rod 601 is connected to the outer surface of the volute 2011 and the outer surface of the wind tunnel 60, the limiting part limits the support rod 601 to the outside, so as to prevent the support rod 601 from falling off when the connection between the support rod 601 and the wind tunnel 60 or the volute 2011 becomes loose.

[0184] Optionally, the first air duct 10 is located above the second air duct 20 to make the structure of the air conditioner more compact and the layout more reasonable.

[0185] In one specific embodiment, the first fan 101 and the first heat exchanger are both higher than the second fan 201 and the second heat exchanger 202. In this embodiment, the first fan 101 and the first heat exchanger are arranged vertically with the second fan 201 and the second heat exchanger 202, which can make full use of the space in the height direction of the shell 1 and save space in the width and thickness of the shell 1.

[0186] Optionally, such as Figure 7 As shown, the height of the first air inlet 104 is greater than the height of the second air inlet 204. In this embodiment, the greater height of the first air inlet 104 reduces the flow path of the airflow in the first air duct 10 and the second air duct 20, and also avoids interference between the airflow in the first air duct 10 and the airflow in the second air duct 20.

[0187] Optionally, the first air outlet 103 and the first air inlet 104 are arranged opposite to each other.

[0188] In this embodiment, the first air outlet 103 and the first air inlet 104 are arranged opposite to each other, which further shortens the flow path of the airflow in the first air duct 10, thereby reducing the loss of airflow in the first air duct 10.

[0189] Optionally, the air outlet 303 of the flow guide cylinder matches the first air outlet 103 and the third air outlet 407. It can be understood that the shape and size of the air outlet 303 of the flow guide cylinder are the same as or similar to those of the third air outlet 407 and the first air outlet 103. The mixing area of the air flow out of the air outlet 303 of the flow guide cylinder, the air flow out of the first air inlet 104 and the air flow out of the third air outlet 407 is increased, so that the air flows out of the first air duct 10, the second air duct 20 and the third air duct 405 are mixed more uniformly.

[0190] Optionally, the extension direction of the air outlet 303 of the flow guide cylinder is consistent with the extension direction of the first air outlet 103 and the third air outlet 407.

[0191] In this embodiment, the extension direction of the air outlet 303 of the flow guide cylinder is consistent with the extension direction of the first air outlet 103, which increases the mixing area of the air flow out of the air outlet 303 of the flow guide cylinder and the air flow out of the first air inlet 104, so that the air flow out of the second air duct 20 and the air flow out of the first air inlet 104 are mixed more uniformly.

[0192] For example, the air outlet 303 of the flow guide cylinder is in a strip shape, and the first air outlet 103 and the third air outlet 407 are also in a strip shape. The air outlet 303 of the flow guide cylinder is in an arc shape, and the first air outlet 103 and the third air outlet 407 are also in an arc shape.

[0193] Optionally, the size of the air outlet 303 of the flow guide cylinder, the size of the first air outlet 103 and the size of the third air outlet 407 are matched. In this way, the air flow out of the air outlet 303 of the flow guide cylinder, the air flow out of the first air outlet 103 and the air flow out of the third air outlet 407 are mixed more uniformly.

[0194] Optionally, the front surface of the front shell 11 protrudes from the front surface of the flow guide cylinder 30.

[0195] In this embodiment, the air flow out of the first air outlet 103 can not only better guide the air flow in the third air duct 405 to flow out through the third air outlet 407, but also better adjust the direction of the air flow out of the first air duct 10.

[0196] Optionally, as Figure 26 and Figure 27As shown, the first position is the off position, and the second position is the maximum wide-angle air outlet position. The guide cylinder 30 can rotate between the maximum wide-angle air outlet position and the off position. When the guide cylinder 30 rotates to the maximum wide-angle air outlet position, the air outlet 303 of the guide cylinder faces away from the first air duct 10. When the guide cylinder 30 rotates to the off position, the air outlet 303 of the guide cylinder faces the first air duct 10. When the air conditioner is turned on, the guide cylinder 30 can rotate from the off position to the maximum wide-angle air outlet position towards the front side.

[0197] In this embodiment, when the guide cylinder 30 is in the maximum wide-angle air outlet position, the air outlet 303 of the guide cylinder faces away from the first air duct 10, and the air is dispersed, which is suitable for the situation of crowd dispersion. When the guide cylinder 30 is in the off position, the air outlet 303 of the guide cylinder faces the first air duct 10. The first guide cylinder 301 and the second guide cylinder 302 can rotate between the maximum wide-angle air outlet position and the off position, which can realize multiple air outlet forms and increase the air outlet diversity of the air conditioner.

[0198] Taking the first air outlet 103 as an example, the first guide cylinder 301 and the second guide cylinder 302 are divided into two parts located on both sides of the first air outlet 103 and have a third air duct 405, and the multiple air outlet forms of the air conditioner are described as follows:

[0199] When the user expects the air conditioner to blow directly, the outlet of the first guide cylinder 301, the outlet of the second guide cylinder 302, and the first air outlet 103 all face forward, so that the air outlet of the air conditioner all faces forward. At the same time, the airflow flowing out of the outlet of the first guide cylinder 301, the outlet of the second guide cylinder 302, and the first air outlet 103 forms negative pressure at the third air outlet 407. The environmental wind flows to the third air outlet 407 through the third air inlet 406 and the third air duct 405 under the action of the negative pressure at the third air outlet 407, mixes with the air of the second air duct 20 and the first air duct 10, and then flows out, realizing uniform air outlet of the air conditioner and ensuring the air outlet volume.

[0200] When the indoor crowd does not like the direct blowing of the air conditioner, but needs the environmental temperature to be quickly adjusted to the right position, the air outlet volumes of the first guide cylinder 301 and the second guide cylinder 302 can be controlled to be the same, and the first guide cylinder 301 and the second guide cylinder 302 can be adjusted to not face the user. Under the action of the vector adjustment, the air outlet of the first air outlet 103 can not face the user. At the same time, the airflow flowing out of the outlet of the first guide cylinder 301, the outlet of the second guide cylinder 302, and the first air outlet 103 forms negative pressure at the third air outlet 407. The environmental wind flows to the third air outlet 407 through the third air inlet 406 and the third air duct 405 under the action of the negative pressure at the third air outlet 407, mixes with the air of the second air duct 20 and the first air duct 10, and then flows out. Finally, uniform air outlet, wind avoidance, and large air volume without direct blowing to the user are realized.

[0201] When the indoor space is large and the air supply distance is far, the first air outlet 103 or the air outlet 303 of the guide cylinder cannot send the air to the target position, the outlet of the first guide cylinder 301 and the outlet of the second guide cylinder 302 are both deviated from the first air outlet 103, and then the aggregated long-distance straight blowing mode is formed. At the same time, the air flows out of the outlet of the first guide cylinder 301, the outlet of the second guide cylinder 302 and the first air outlet 103, so that a negative pressure is formed at the third air outlet 407. The ambient wind flows to the third air outlet 407 through the third air inlet 406 and the third air duct 405 under the action of the negative pressure of the third air outlet 407, and then flows out after mixing with the air of the second air duct 20 and the first air duct 10. The uniform air outflow and the long-distance air supply effect can be realized.

[0202] When the user needs to quickly adjust the indoor temperature, the outlet of the first guide cylinder 301 and the outlet of the second guide cylinder 302 are both deviated from the first air outlet 103, and at the same time, the air flows out of the outlet of the first guide cylinder 301, the outlet of the second guide cylinder 302 and the first air outlet 103, so that a negative pressure is formed at the third air outlet 407. The ambient wind flows to the third air outlet 407 through the third air inlet 406 and the third air duct 405 under the action of the negative pressure of the third air outlet 407, and then flows out after mixing with the air of the second air duct 20 and the first air duct 10. The range of the air outlet of the air conditioner is increased, the air can be supplied in a large range, and the purpose of uniform air outflow and quick adjustment of indoor temperature can be realized.

[0203] When the indoor personnel include both users who do not like air conditioning straight blowing and users who like straight blowing, the air volume of the first guide cylinder 301 and the second guide cylinder 302 can be controlled to be different. The guide cylinder 30 facing the user who likes straight blowing can be in a large air volume mode, and the guide cylinder 30 facing the user who does not like straight blowing can be in a small air volume mode. At the same time, the first air outlet 103 normally blows air. The air flows out of the outlet of the first guide cylinder 301, the outlet of the second guide cylinder 302 and the first air outlet 103, so that a negative pressure is formed at the third air outlet 407. The ambient wind flows to the third air outlet 407 through the third air inlet 406 and the third air duct 405 under the action of the negative pressure of the third air outlet 407, and then flows out after mixing with the air of the second air duct 20 and the first air duct 10. While meeting the needs of various personnel, the air conditioner can realize uniform air outflow and can also ensure quick temperature adjustment.

[0204] When the indoor temperature is generally high or generally low, the air conditioner does not need to run at high speed and large air volume at the beginning, and the first fan 101 and the second fan 201 can be selected to run at low speed, or only one of the first heat exchanger or the second heat exchanger 202 is opened, and the first fan 101 and the second fan 201 are normally operated. The airflow flowing out of the outlet of the first flow guide cylinder 301, the outlet of the second flow guide cylinder 302 and the first air outlet 103 forms a negative pressure at the third air outlet 407, and the ambient wind flows to the third air outlet 407 through the third air inlet 406 and the third air duct 405 under the action of the negative pressure at the third air outlet 407, and the ambient wind mixes with the air of the second air duct 20 and the first air duct 10 and then flows out. While ensuring temperature adjustment, uniform air outlet is realized, and the energy consumption of the air conditioner is reduced.

[0205] When the indoor personnel are relatively dispersed, the first flow guide cylinder 301 and the second flow guide cylinder 302 are rotated to the maximum wide-angle air outlet position, and the first air outlet 103 faces forward to blow air. The air conditioner can form a wall-hugging surrounding air supply, realize surrounding air supply without blowing people, and make indoor personnel feel the air outlet of the air conditioner.

[0206] Optionally, the indoor unit further comprises a second detection device for detecting user information; the controller is electrically connected with the second detection device and the driving device 50, and the controller can receive user information and control the driving device 50 to move according to the user information.

[0207] In this embodiment, the indoor unit of the air conditioner collects user information through the second detection device, and then controls the driving device 50 to rotate according to the user information, so that the air outlet of the air conditioner can reach the best comfort of the user.

[0208] In this embodiment, the first air duct 10 and the second air duct 20 can flow out heat exchange air or ambient air by controlling the opening and closing of the corresponding heat exchangers, wherein one of the first air duct 10 and the second air duct 20 flows out ambient air driven by the fan, and the mixed air flowing out after the ambient air mixes with the heat exchange air flowing out of the other of the first air duct 10 and the second air duct 20 can be called active uniform air. The ambient air flowing out of the third air outlet 407 under the condition that the third air outlet 407 forms a negative pressure due to the air outlet of the first air outlet 103 or the air outlet of the flow guide cylinder 303, and the mixed air flowing out after mixing with the heat exchange air flowing out of the first air outlet 103 or the air outlet of the flow guide cylinder 303 can be called passive uniform air.

[0209] The indoor unit of the air conditioner of this embodiment can realize wide-angle air supply, uniform air outlet mode, and aggregation air supply, and the uniform air outlet mode can further include passive uniform air, active uniform air, mixed uniform air, and mixed uniform air, that is, the coexistence of active and passive uniform air, and other air outlet modes, which increases the air outlet mode of the air conditioner and meets the use demand of the user for various air outlets.

[0210] Optionally, the air conditioner can be a cabinet air conditioner, a wall-mounted air conditioner, etc.

[0211] Optionally, as shown in FIGS. 1 and 2, the air conditioner can further comprise a guide cylinder 30. Figure 9 and Figure 10 As shown in FIGS. 1 and 2, the guide cylinder 30 comprises a shell 305, the shell 305 defining an air outlet duct 306, the air outlet duct 306 being in communication with the second air duct 20. The shell 305 comprises a first end portion 3081, a second end portion 3082, and an annular sidewall 308 connected between the first end portion 3081 and the second end portion 3082, and the air outlet 303 of the guide cylinder is arranged at the annular sidewall 308.

[0212] In this embodiment, the annular sidewall 308 of the guide cylinder 30 is relatively long, and the air outlet 303 of the guide cylinder is arranged at the annular sidewall 308, thereby increasing the air outlet area of the guide cylinder 30 and further increasing the air outlet volume of the air conditioner. Moreover, it is convenient to match the air outlet 303 of the guide cylinder with the first air outlet 103, fully utilize the structural space inside the guide cylinder 30, and save the space occupied by the indoor unit of the air conditioner.

[0213] Optionally, the shell 305 of the guide cylinder 30 defines the air outlet duct 306, the air outlet duct 306 being in communication with the inlet of the guide cylinder 30 and the air outlet 303 of the guide cylinder; the guide cylinder 30 further comprises a partition plate 307, the partition plate 307 being arranged in the air outlet duct 306 and separating the air outlet duct 306 into a plurality of sub-air outlet ducts 3061; wherein each of the plurality of sub-air outlet ducts 3061 is in communication with the inlet of the guide cylinder 30 and the air outlet 303 of the guide cylinder.

[0214] In this embodiment, the partition plate 307 separates the air outlet duct 306 into a plurality of sub-air outlet ducts 3061, and since each of the plurality of sub-air outlet ducts 3061 is in communication with the inlet of the guide cylinder 30 and the air outlet 303 of the guide cylinder, each of the plurality of sub-air outlet ducts 3061 can guide the airflow flowing into the inlet of the guide cylinder 30 to the air outlet 303 of the guide cylinder. The plurality of sub-air outlet ducts 3061 can be used to adjust the air outlet volume of each part of the air outlet 303 of the guide cylinder.

[0215] Optionally, the partition plate 307 is arranged on the inner wall surface of the air outlet duct 306 and located at the air outlet 303 of the guide cylinder.

[0216] In this embodiment, the partition plate 307 is arranged at the air outlet 303 of the guide cylinder, which can more accurately guide the airflow at the inlet of the guide cylinder 30 to the air outlet 303 of the guide cylinder, so that the air outlet of the air outlet 303 of the guide cylinder is convenient to adjust.

[0217] Optionally, the inlet of the flow guide cylinder 30 is arranged at the first end portion 3081 and / or the second end portion 3082, the baffle 307 comprises a first connecting section 3071 and a second connecting section 3072, the first connecting section 3071 extends along the length direction of the flow guide cylinder 30, one end of the first connecting section 3071 is located in the air outlet duct 306, the first connecting section 3071 is located at the air outlet 303 side of the flow guide cylinder, and there is a gap between the first connecting section 3071 and the inner wall surface of the flow guide cylinder 30 opposite to the air outlet 303 of the flow guide cylinder, so as to facilitate the airflow to pass through; the second connecting section 3072 extends along the radial direction of the flow guide cylinder 30, one end of the second connecting section 3072 is connected with the other end of the first connecting section 3071, and the other end of the second connecting section 3072 is located at the air outlet 303 of the flow guide cylinder; wherein, along the flow direction of the airflow in the air outlet duct 306, the first connecting section 3071 and the second connecting section 3072 are sequentially arranged.

[0218] In the embodiment, the inlet of the flow guide cylinder 30 is arranged at the first end portion 3081 and / or the second end portion 3082, the air outlet 303 of the flow guide cylinder is arranged at the annular side wall 308, and the airflow needs to flow along the length direction of the flow guide cylinder 30 first, and then flow along the radial direction of the flow guide cylinder 30. The first connecting section 3071 is used for guiding the airflow at the inlet of the flow guide cylinder 30 to flow to the second connecting section 3072, and the second connecting section 3072 is used for guiding the airflow at the first connecting section 3071 to flow to the air outlet 303 of the flow guide cylinder. Through the first connecting section 3071 and the second connecting section 3072, the airflow at the inlet of the flow guide cylinder 30 can be more effectively guided to the air outlet 303 of the flow guide cylinder.

[0219] Optionally, the baffle 307 further comprises a third connecting section 3073, one end of the third connecting section 3073 is connected with the other end of the first connecting section 3071, and the other end of the third connecting section 3073 is connected with one end of the second connecting section 3072; wherein, the second connecting section 3072 is in an arc shape, and the opening of the arc shape faces the air outlet 303 of the flow guide cylinder.

[0220] In the embodiment, the third connecting section 3073 can guide the airflow flowing from the first connecting section 3071 to the second connecting section 3072. The third connecting section 3073 is in an arc shape, which can make the flow resistance of the airflow smaller and reduce the loss in the airflow flow process.

[0221] Optionally, the number of the baffles 307 is multiple, and the multiple baffles 307 are sequentially and spacedly arranged along the length direction of the flow guide cylinder 30.

[0222] In the embodiment, the multiple baffles 307 are sequentially and spacedly arranged along the length direction of the flow guide cylinder 30, which can adjust the air outlet quantity of each part of the air outlet 303 of the flow guide cylinder along the length direction.

[0223] Optionally, the plurality of partitions 307 are arranged along the length direction of the guide cylinder 30 in sequence and at intervals, and in order to ensure that the air outlet of each sub-air outlet channel 3061 is relatively uniform, the intervals between the plurality of partitions 307 are different. For example, along the flow direction of the airflow in the air outlet channel 306, the distance between the first connecting section 3071 of the plurality of partitions 307 and the air outlet 303 of the guide cylinder gradually increases.

[0224] In this embodiment, the distance between the first connecting section 3071 of the plurality of partitions 307 and the air outlet 303 of the guide cylinder gradually increases, which can be understood as that the length of the second connecting section 3072 along the radial direction of the guide cylinder 30 gradually increases. In this way, along the flow direction of the airflow in the air outlet channel 306, the distance between the first connecting section 3071 and the inner wall surface of the air outlet channel 306 away from the air outlet 303 of the guide cylinder gradually decreases, that is, along the flow direction of the airflow in the air outlet channel 306, the flow area of each sub-air outlet channel 3061 along the radial direction and the inlet of the guide cylinder 30 gradually increases.

[0225] The shorter the distance from the inlet of the guide cylinder 30 in the air outlet channel 306, the faster the wind speed, so the sub-air outlet channel 3061 close to the inlet of the guide cylinder 30 has a smaller flow area along the radial direction and the inlet of the guide cylinder 30, which can guide enough airflow to flow out. At the same time, the distance between the first connecting section 3071 close to the inlet of the guide cylinder 30 and the air outlet channel 306 away from the air outlet 303 of the guide cylinder is larger, which can make more airflow flow into the sub-air outlet channel 3061 away from the inlet of the guide cylinder 30.

[0226] Through the arrangement of the partition 307 in this embodiment, the air outlet of each sub-air outlet channel 3061 is more uniform, and the uniform air outlet of the air conditioner can be realized.

[0228] In this embodiment, the rotating part is used to cooperate with the driving device 50, and the driving device 50 can drive the guide cylinder 30 to rotate, thereby changing the air outlet direction of the air outlet 303 of the guide cylinder, increasing the air outlet range of the air conditioner, and diversifying the air outlet of the air conditioner.

[0229] Optionally, the rotating part is arranged at the first end part 3081 and / or the second end part 3082, which facilitates the connection between the driving device 50 and the rotating part and the arrangement of the driving device 50.

[0235] In this embodiment, the cross section of the flow guide cylinder 30 is oval-like, and the air outlet 303 of the flow guide cylinder is arranged at the long axis end of the oval-like shape, so that the air outlet of the flow guide cylinder 30 is more concentrated, and the extension length of the partition plate 307 along the radial direction of the flow guide cylinder 30 is increased, so that the partition plate 307 can more fully separate the airflow in the air outlet air duct 306.

[0237] In this embodiment, the fixing piece 404 enables the rotating shaft 309 of the flow guide cylinder 30 to rotate stably, thereby improving the stability of the rotation of the flow guide cylinder 30 and avoiding the situation of jamming and falling off during the rotation of the flow guide cylinder 30.
