Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples.

In addition, examples of various specific processes and materials are provided in this invention; however, those skilled in the art will recognize the applicability of other processes and / or the use of other materials.

[0033] The air conditioner 100 of this utility model is described below with reference to the accompanying drawings.

[0034] According to the embodiment of the present utility model, the air conditioner 100, such as Figure 1 and Figure 2 As shown, the air conditioner 100 includes: a housing 1 and a ventilation and heat exchange component 2. The length direction of the housing 1 is vertical. One of the left wall surface 11 and the right wall surface 12 of the housing 1 is a first side wall 1a, and the other is a second side wall 1b. The intersection of the first side wall 1a and the front wall surface 13 of the housing 1 is an air outlet corner 15. The air outlet 16 of the air conditioner 100 is formed at the air outlet corner 15. At least a portion of the air inlet 17 of the air conditioner 100 is formed on the second side wall 1b and / or the rear wall surface 14 of the housing 1. The ventilation and heat exchange component 2 is disposed inside the housing 1 and is used to draw in airflow from the air inlet 17, exchange heat with the airflow, and then send the airflow out from the air outlet 16.

[0035] An air outlet 16 is provided at the intersection of the first side wall 1a and the front wall surface 13 of the housing 1. The intersection of the second side wall 1b and the rear wall surface 14 is the point on the housing 1 furthest from the air outlet 16 in the horizontal cross-section. The air conditioner 100 of this embodiment can be used at a corner 200, with the second side wall 1b and the rear wall surface 14 close to the wall. Alternatively, the air conditioner 100 of this embodiment can be used close to the wall, with the second side wall 1b close to the wall or the rear wall surface 14 close to the wall.

[0036] When the air conditioner 100 is used in a corner 200, the air outlet corner 15 is positioned away from the corner 200. The air outlet 16 located at the air outlet corner 15 can generate airflow in both the side and front directions. Compared to solutions with only front or only side airflow, the air supply angle of the air conditioner 100 is larger, which can improve the air supply effect. Furthermore, the air inlet 17 formed on the second side wall 1b and the rear wall surface 14 of the housing 1 is far from the air outlet 16, which reduces the risk of backflow short circuits. In addition, the housing 1 has a larger area for the air inlet 17, increasing the air volume.

[0037] Optionally, such as Figure 2 As shown, the right wall 12 of the housing 1 is the first side wall 1a, the left wall 11 of the housing 1 is the second side wall 1b, and an air outlet 16 is formed at the intersection of the right wall 12 and the front wall 13. The air conditioner 100 can blow air to the right and front. At this time, the left wall 11 of the air conditioner 100 is set close to the corner 200.

[0038] Alternatively, the left wall 11 of the housing 1 is the first side wall 1a, the right wall 12 of the housing 1 is the second side wall 1b, and an air outlet 16 is formed at the intersection of the left wall 11 and the front wall 13. The air conditioner 100 can blow air to the left and front. In this case, the right wall 12 of the air conditioner 100 is set close to the corner 200.

[0039] One of the left wall surface 11 and the right wall surface 12 of the housing 1 is a first side wall 1a, and the other of the left wall surface 11 and the right wall surface 12 is a second side wall 1b. This can be selected according to actual needs to improve the application range of the air conditioner 100. For example, when the right wall of the user's living room is full of large appliances, while the left wall has sufficient space, an air outlet 16 can be formed at the intersection of the right wall surface 12 and the front wall surface 13, so that the air conditioner 100 can discharge air to the right and front.

[0040] The ventilation and heat exchange component 2 is used to provide airflow. The ventilation and heat exchange component 2 draws in airflow from the air inlet 17 and then sends the airflow out from the air outlet 16. The ventilation and heat exchange component 2 also exchanges heat on the airflow and sends the heat-exchanged airflow out from the air outlet 16, thereby regulating the indoor temperature.

[0041] According to the embodiment of this utility model, when the air conditioner 100 is used in a corner 200, the air outlet corner 15 is arranged away from the corner 200. The air outlet 16 located at the air outlet corner 15 can generate airflow in both the side and front directions. Compared with airflow only from the front or only from the side, the air supply angle of the air conditioner 100 is larger, which can improve the air supply effect. Furthermore, the air inlet 17 formed on the second side wall 1b and the rear wall surface 14 of the housing 1 is far from the air outlet 16, which reduces the risk of backflow short circuit. In addition, the housing 1 has a larger area for the air inlet 17, which increases the air volume.

[0042] Optionally, the first sidewall 1a can be entirely planar; or, the first sidewall 1a can also be entirely curved; or, optionally, the first sidewall 1a can be a combination surface of a planar surface and a curved surface. Similarly, the second sidewall 1b can be entirely planar; or, the second sidewall 1b can also be entirely curved; or, optionally, the second sidewall 1b can be a combination surface of a planar surface and a curved surface.

[0043] The first sidewall 1a or the second sidewall 1b may include a curved surface, thereby increasing the distance between the first sidewall 1a or the second sidewall 1b and the wall, which is conducive to airflow and to the air intake and exhaust of the air conditioner 100.

[0044] Optionally, the front wall surface 13 can be entirely planar; or, the front wall surface 13 can also be entirely curved; or, alternatively, the front wall surface 13 can be a combination of planar and curved surfaces.

[0045] Optionally, the rear wall surface 14 can be entirely planar; or, the front and rear wall surfaces 14 can also be entirely curved; or, alternatively, the rear wall surface 14 can be a combination of planar and curved surfaces.

[0046] In some embodiments of this utility model, such as Figure 2 As shown, the ventilation and heat exchange component 2 includes a fan component 21, which includes a cross-flow impeller 211 with its axis vertically arranged. The air conditioner 100 includes a cross-flow volute 3, which extends from the inlet 3a to the outlet 3b of the cross-flow volute towards the air outlet 16. The cross-flow impeller 211 is fitted at the inlet 3a of the cross-flow volute, and the outlet 3b of the cross-flow volute is located on the side of the cross-flow impeller 211 near the first sidewall 1a.

[0047] The cross-flow impeller 211 provides a flowing airflow, and the cross-flow volute 3 guides the airflow generated by the cross-flow impeller 211 from the inlet 3a of the cross-flow volute 3 at high speed and smoothly to the outlet 3b of the cross-flow volute 3, so as to send the airflow out from the outlet 16.

[0048] like Figure 2 As shown, the cross-flow volute 3 extends from the cross-flow impeller 211 toward the air outlet 16. The outlet 3b of the cross-flow volute is located on the side of the cross-flow impeller 211 near the first side wall 1a. The cross-flow impeller 211 is inclined in the front-back direction toward the left-right direction, which helps to save space in the front-back direction.

[0049] In some embodiments of this utility model, such as Figure 2 As shown, in the horizontal cross-section of the air conditioner 100, the cross-flow volute 3 includes a first air duct wall 31 and a second air duct wall 32 spaced apart to form a cross-flow air duct 33 between the first air duct wall 31 and the second air duct wall 32. The first air duct wall 31 is disposed near the front wall surface 13 relative to the second air duct wall 32 and includes a volute tongue 311. The front wall surface 13 is a plane. The angle A between the extension line of the outlet end of the first air duct wall 31 and the front wall surface 13 is 50°-100°, and the angle B between the extension line of the outlet end of the second air duct wall 32 and the front wall surface 13 is 45°-105°.

[0050] The first air duct wall 31 is positioned closer to the front wall 13 than the second air duct wall 32, and the second air duct wall 32 is positioned closer to the first side wall 1a. The cross-flow volute 3 is inclined in the left and right directions along the front-back direction, which helps to save space in the front-back direction.

[0051] The air outlet angle of the cross-flow duct 33 is formed by the extension line of the outlet end of the first duct wall 31 and the extension line of the outlet end of the second duct wall 32. The angle A between the extension line of the outlet end of the first duct wall 31 and the front wall surface 13 is 50°-100°, and the angle B between the extension line of the outlet end of the second duct wall 32 and the front wall surface 13 is 45°-105°, which can improve the air outlet effect of the air conditioner.

[0052] When the angle A between the extension line of the outlet end of the first air duct wall 31 and the front wall surface 13 is too large, the angle of the volute tongue is too small, which can easily cause airflow turbulence and increase the generated airflow noise; while when the angle A between the extension line of the outlet end of the first air duct wall 31 and the front wall surface 13 is too small, the outlet 3b of the cross-flow volute is too inclined toward the first side wall 1a, which is not conducive to the forward airflow of the air conditioner 100.

[0053] When the angle B between the extension line of the outlet end of the second air duct wall 32 and the front wall surface 13 is too large, the outlet 3b of the cross-flow volute is too inclined toward the second side wall 1b, which is not conducive to the lateral air outlet of the air conditioner 100; when the angle B between the extension line of the outlet end of the second air duct wall 32 and the front wall surface 13 is too small, the outlet 3b of the cross-flow volute is too inclined toward the first side wall 1a, which is not conducive to the forward air outlet of the air conditioner 100.

[0054] Therefore, it is optimal to limit the angle A between the extension line of the outlet end of the first air duct wall 31 and the front wall surface 13 to 50°-100°, and to limit the angle B between the extension line of the outlet end of the second air duct wall 32 and the front wall surface 13 to 45°-105°. This is beneficial for the air conditioner 100 to vent air in both the side and front directions, and also helps to reduce air outlet noise and improve air outlet performance.

[0055] Optionally, the angle A between the extension line of the outlet end of the first air duct wall 31 and the front wall surface 13 can be 50°, 60°, 75°, 90°, 100°, etc. Optionally, the angle B between the extension line of the outlet end of the second air duct wall 32 and the front wall surface 13 can be 45°, 50°, 65°, 100°, 105°, etc.

[0056] In some embodiments of this utility model, such as Figure 3 and Figure 4As shown, in the horizontal cross-section of the air conditioner 100, the front wall 13 includes a first edge 131 defining the side edge of the air outlet 16 near the second side wall 1b, and the first side wall 1a includes a second edge 1a1 defining the rear edge of the air outlet 16. The distance between the first edge 131 and the second edge 1a1 in the left-right direction is a first distance L1. The ventilation and heat exchange component 2 includes a fan component 21, which includes a cross-flow impeller 211 with its axis vertically arranged. The distance between the central axis of the cross-flow impeller 211 and the second edge 1a1 in the left-right direction is a second distance L2. The ratio of the first distance L1 to the second distance L2, L1 / L2, is less than or equal to 0.8.

[0057] The second edge 1a1 is formed on the first sidewall 1a. Therefore, the distance between the first edge 131 and the second edge 1a1 in the left-right direction is the size of the air outlet 16 in the left-right direction. When the ratio of the first distance L1 to the second distance L2, L1 / L2, is greater than 1, the size of the air outlet 16 in the left-right direction is too large. In order to meet the air outlet 16's front air outlet, the air outlet of the cross-flow fan 211 will be deflected forward. This will also cause the noise generated by the cross-flow fan 211 to leak out from the front, increasing the operating noise of the air conditioner 100.

[0058] Therefore, by designing the ratio of the first spacing L1 to the second spacing L2, L1 / L2, to be less than or equal to 0.8, the size of the air outlet 16 in the left and right directions is reduced, and the air outlet direction of the cross-flow fan 211 is shifted to the side, which can reduce the airflow noise of the air conditioner 100.

[0059] In some embodiments of this utility model, such as Figure 3 and Figure 4 As shown, the air inlet 17 includes a front air inlet 171 formed on the front wall surface 13. The air conditioner 100 can not only draw air through the air inlet 17 on the second side wall 1b or the air inlet 17 on the rear wall surface 14, but also through the air inlet 17 on the front wall surface 13, which helps to increase the air intake of the air conditioner 100.

[0060] By designing the ratio of the first spacing L1 to the second spacing L2, L1 / L2, to be less than or equal to 0.8, the size of the air outlet 16 on the front wall surface 13 is reduced, which increases the distance between the air outlet 16 and the front air inlet 171, reduces the situation where the air outlet of the air conditioner 100 flows directly back to the air conditioner 100 from the front air inlet 171, reduces the front return air phenomenon, and reduces the air volume loss of the air conditioner 100.

[0061] It is worth noting that the first sidewall 1a can be a plane as a whole; or, the first sidewall 1a can also be a curved surface as a whole; or, alternatively, the first sidewall 1a can be a combination of a plane and a curved surface.

[0062] When the first sidewall 1a has a curved surface, the distance between the first edge 131 and the second edge 1a1 in the left-right direction refers to the distance from the first edge 131 to the front end of the second edge 1a1 in the left-right direction.

[0063] In some embodiments of this utility model, such as Figure 5 As shown, in the horizontal cross-section of the air conditioner 100, the first sidewall 1a includes a second edge 1a1 that defines the rear end edge of the air outlet 16. The ventilation and heat exchange component 2 includes a fan component 21. The fan component 21 includes a cross-flow impeller 211 with its axis vertically arranged. The central axis of the cross-flow impeller 211 is positioned relative to the second edge 1a1 and close to the rear wall surface 14. The distance between the central axis of the cross-flow impeller 211 and the second edge 1a1 in the front-rear direction is a third distance L3. The ratio of the third distance L3 to the radius R of the cross-flow impeller, L3 / R, is greater than or equal to 0.8.

[0064] The second edge 1a1 is located on the side wall of the housing 1. The third spacing L3 is the distance from the central axis of the cross-flow fan 211 to the second edge 1a1 in the front-back direction. The distance from the central axis of the cross-flow fan 211 to the front edge of the cross-flow fan 211 in the front-back direction is the radius R of the cross-flow fan 211. When the ratio L3 / R of the third spacing L3 to the radius R of the cross-flow fan is too small, the rear edge of the air outlet 16 is too close to the rear, causing the air outlet 16 to deviate towards the direction of the first side wall 1a, which is not conducive to the forward air outlet of the air conditioner 100.

[0065] Therefore, by designing the ratio of the third spacing L3 to the radius R of the cross-flow impeller to be greater than or equal to 0.8, it is beneficial to the uniformity of airflow in both the forward and side directions, thus improving the airflow effect.

[0066] In some embodiments of this utility model, such as Figure 3 and Figure 4 As shown, in the horizontal cross-section of the air conditioner 100, the front wall 13 includes a first edge 131 that defines the air outlet 16 near the side edge of the second side wall 1b, and the first side wall 1a includes a second edge 1a1 that defines the rear edge of the air outlet 16. The distance between the first edge 131 and the second edge 1a1 in the left-right direction is a first distance L1, and the distance between the first edge 131 and the second edge 1a1 in the front-rear direction is a fourth distance L4. The ratio of the fourth distance L4 to the first distance L1, L4 / L1, is 0.5-2.

[0067] The first spacing L1 is the opening size of the air outlet 16 facing forward, and the fourth spacing L4 is the opening size of the air outlet 16 facing to the side. When the ratio of the fourth spacing L4 to the first spacing L1, L4 / L1, is less than 1, the air outlet of the air conditioner 100 is biased towards the front, and the air volume of the air conditioner 100 facing forward is larger. When the ratio of the fourth spacing L4 to the first spacing L1, L4 / L1, is greater than 1, the air outlet of the air conditioner 100 is biased towards the side, and the air volume of the air conditioner 100 facing to the side is larger.

[0068] In some embodiments of this utility model, the ratio of the fourth spacing L4 to the first spacing L1, L4 / L1, is 1, and the air volume from the front and the side of the air conditioner 100 is uniform, which can take into account the air supply from both the front and the side and improve the air supply effect.

[0069] In some embodiments of this utility model, such as Figure 1 and Figure 5 As shown, the air inlet 17 includes a forward air inlet 171 formed on the front wall surface 13.

[0070] The air conditioner 100 can not only take in air through the air inlet 17 on the second side wall 1b or the air inlet 17 on the rear wall 14, but also take in air through the front air inlet 171 on the front wall 13. The dotted line with arrows in the figure indicates the direction of airflow, which helps to increase the air intake of the air conditioner 100.

[0071] In some embodiments of this utility model, such as Figure 5 As shown, the front air vent 171 is disposed in the left-right direction relative to the air outlet 16 near the second side wall 1b. The ventilation and heat exchange component 2 includes a heat exchange component 22, which includes a heat exchanger 221. The heat exchanger 221 includes a front extension 2211 extending from the second side wall 1b toward the air outlet 16. At least a portion of the front extension 2211 is located on the rear side of the front air vent 171. The front wall surface 13 includes a first edge 131 defining a side edge of the air outlet 16 near the second side wall 1b. The distance between the end of the front extension 2211 near the air outlet 16 and the first edge 131 in the left-right direction is a fifth distance L5, which is greater than 50 mm.

[0072] Heat exchanger 221 is used to exchange heat with the airflow flowing in from the air inlet 17. A portion of the front extension 2211 of heat exchanger 221 is located behind the air inlet 171, which can improve the heat exchange efficiency of the airflow flowing into the air conditioner 100 from the air inlet 171. It is understood that the air inlet 17 of the air conditioner 100 includes not only the air inlet 171 formed on the front wall surface 13, but also the air inlet 17 formed on the second side wall 1b and / or the rear wall surface 14. Therefore, a portion of heat exchanger 221 extends to the rear of the air inlet 171 to exchange heat with the airflow flowing in from the air inlet 171, thereby improving the heat exchange efficiency of heat exchanger 221 on the airflow and helping to improve the uniformity of the air outlet temperature of the air conditioner 100.

[0073] The size of the front extension 2211 near the air outlet 16 is related to the size of the front air inlet 171 in the left-right direction. Since the front air inlet 171 is close to the first sidewall 1a in the left-right direction, the distance that the end of the front extension 2211 near the air outlet 16 extends toward the first sidewall 1a also increases accordingly. By limiting the distance between the end of the front extension 2211 near the air outlet 16 and the first edge 131 in the left-right direction to be greater than 50mm, the distance between the air outlet 16 and the front air inlet 171 is increased, reducing the situation where the air outlet of the air conditioner 100 flows directly back to the air conditioner 100 from the front air inlet 171, reducing the front return air phenomenon, and helping to reduce the air volume loss of the air conditioner 100.

[0074] In some embodiments of this utility model, such as Figure 6 As shown, the air inlet 17 of the air conditioner 100 includes a side air inlet 172 formed on the second side wall 1b and a rear air inlet 173 formed on the rear wall surface 14. Air inlets 17 are formed on both the second side wall 1b and the rear wall surface 14. The dotted lines with arrows in the figure indicate the direction of airflow, which can increase the air intake volume of the air conditioner 100.

[0075] like Figure 6 As shown, the rear air inlet 173 is positioned in the left-right direction relative to the first side wall 1a and close to the second side wall 1b. The heat exchange component 22 includes a heat exchanger 221, which includes a rear extension 2212 extending from the side air inlet 172 toward the rear air inlet 173.

[0076] The rear extension 2212 of the heat exchange component 22 is located near the side air inlet 172 and the rear air inlet 173. On the one hand, it can simplify the arrangement of the heat exchanger 221, and on the other hand, it can improve the heat exchange efficiency of the heat exchanger 221 for the airflow, which is conducive to improving the uniformity of the air outlet temperature of the air conditioner 100.

[0077] In some embodiments of this utility model, such as Figure 4As shown, the air conditioner 100 is suitable to be installed at a corner 200, which is defined by a rear wall 201 and a side wall 202. The rear wall surface 14 is positioned close to the rear wall 201 relative to the front wall surface 13, and the second side wall 1b is positioned close to the side wall 202 relative to the air outlet corner 15. The connection corner between the rear wall surface 14 and the second side wall 1b is formed as a folded structure or a curved structure.

[0078] By forming an angled structure or a curved structure at the connection bend between the rear wall 14 and the second side wall 1b, the gap between the air conditioner 100 and the wall can be increased, which is beneficial to airflow.

[0079] In some embodiments of this utility model, such as Figure 4 As shown, the rear air inlet 173 is located at the corner structure where the rear wall 14 and the second side wall 1b meet. The dotted line with arrows in the figure indicates the direction of airflow, which helps to increase the air intake of the rear air inlet 173.

[0080] Optionally, the rear wall 14 and the second side wall 1b are integral parts, which can improve the structural stability of the housing 1; or, alternatively, the rear wall 14 and the second side wall 1b are separate parts.

[0081] In some embodiments of this utility model, the connection bend between the rear wall surface 14 and the first side wall 1a is formed as a folded structure or a curved surface structure, improving the overall integrity of the air conditioner 100. The rear wall surface 14 and the first side wall 1a are integral parts; or the rear wall surface 14 and the first side wall 1a are separate parts, which can be flexibly processed according to actual needs.

[0082] In some embodiments of this utility model, such as Figure 6 As shown, the air inlet 17 includes a side air inlet 172 formed on the second side wall 1b. The distribution dimension of the side air inlet 172 in the front-back direction is greater than 2 / 3 of the dimension of the second side wall 1b in the front-back direction. The large side air inlet area is beneficial to increasing the air intake volume of the air conditioner 100.

[0083] In some embodiments of this utility model, the connection bend between the front wall surface 13 and the second side wall 1b is formed as a folded structure or a curved surface structure.

[0084] The air conditioner 100 includes a front air inlet 171 and a side air inlet 172. At least a portion of at least one of the front air inlet 171 and the side air inlet 172 is formed at the junction of the front wall surface 13 and the second side wall 1b, which facilitates the air intake of the air conditioner 100.

[0085] Optionally, the front wall 13 and the second side wall 1b are integral parts, which can improve the structural stability of the housing 1; or, alternatively, the front wall 13 and the second side wall 1b are separate parts.

[0086] In some embodiments of this utility model, the junction between the front wall 13 and the first side wall 1a is also formed as a bend or a curved structure, improving the overall integrity of the air conditioner 100. The air outlet 16 of the air conditioner 100 is formed at the junction between the front wall 13 and the first side wall 1a, which facilitates the arrangement and opening of the air outlet 16.

[0087] Optionally, the front wall 13 and the first side wall 1a are integral parts, which can improve the structural stability of the housing 1; or, alternatively, the front wall 13 and the first side wall 1a are separate parts.

[0088] In some embodiments of this utility model, such as Figure 2 As shown, the ventilation and heat exchange component 2 includes a heat exchange component 22 and a fan component 21 arranged sequentially along the direction from the second side wall 1b to the first side wall 1a. The housing 1 has a front-to-back dimension equal to the thickness of the air conditioner 100, and a left-to-right dimension equal to the width of the air conditioner 100. The thickness of the air conditioner 100 is less than the width of the air conditioner 100.

[0089] That is, the heat exchange component 22 is positioned in the left-right direction relative to the fan component 21, close to the second side wall 1b. This arrangement of the fan component 21 and the heat exchange component 22 saves space in the front-back direction, reducing the overall size and floor space of the unit. It is worth noting that the length of the housing 1 in the vertical direction is less than or equal to the height of the air conditioner 100, and the width of the air conditioner 100 is less than the length of the housing 1.

[0090] In some embodiments of this utility model, such as Figure 4 As shown, the air conditioner 100 is adapted to be located at a corner 200, which is defined by a rear wall 201 and a side wall 202. The rear wall surface 14 is disposed near the rear wall 201 relative to the front wall surface 13, and the second side wall 1b is disposed near the side wall 202 relative to the air outlet corner 15. At least a portion of at least one of the rear wall surface 14 and the front wall surface 13 is a flat plate structure, adapted to be arranged parallel to the rear wall 201.

[0091] At least a portion of the rear wall 14 is a flat plate structure, which facilitates the arrangement of the air conditioner 100 parallel to the rear wall 201, making it easier to place the air conditioner 100 and reducing its space occupation. At least a portion of the front wall 13 is a flat plate structure, and the arrangement of the air conditioner 100 parallel to the rear wall 201 can increase the air supply angle of the air conditioner 100 and improve the air supply effect.

[0092] In some embodiments of this utility model, such as Figure 2 As shown, the air conditioner 100 also includes an air guide component 4 disposed at the air outlet 16. The air guide component 4 can guide the airflow at the air outlet 16 to improve the air outlet effect of the air conditioner 100.

[0093] like Figure 2 As shown, the air guide component 4 closes the air outlet 16, and the air conditioner 100 does not blow air; or, the air conditioner 100 blows air through the micro-holes on the air guide component 4, and the air conditioner 100 achieves windless air delivery, and the air conditioner 100 delivers air to the front and right at the same time.

[0094] like Figure 4 As shown, the air guide component 4 opens the air outlet 16, and the air conditioner 100 outputs air normally. The air conditioner 100 simultaneously sends air forward and to the right, and the air delivery angle of the air conditioner 100 is relatively large.

[0095] like Figure 5 As shown, the air guide component 4 opens the air outlet 16 and directs the airflow to the right, so the air conditioner 100 mainly supplies air to the right. When the air conditioner 100 is used in a corner 200, the air conditioner 100 supplies air to the right side and sends it along the wall, which can quickly deliver it to a farther place in the room, quickly reduce the indoor temperature difference, and improve the efficiency of regulating indoor temperature.

[0096] like Figure 6 As shown, the air guide component 4 opens the air outlet 16 and directs the airflow forward, so the air conditioner 100 mainly blows air forward. When the air conditioner 100 is used in a corner 200, the air supplied by the air conditioner 100 towards the front is directly delivered to the center of the room or blown directly on the user, which can quickly regulate the user's body surface temperature.

[0097] In some embodiments of this utility model, the air guiding component 4 includes one or more air guiding plates. When there are multiple air guiding plates, the multiple air guiding plates are independently controlled to form different air delivery angles, which can improve the air delivery effect of the air conditioner 100.
