Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to an air conditioner. Background Technology

[0002] Air conditioners in related technologies typically include a housing, a heat exchanger, and a fan assembly. The heat exchanger and fan assembly are located inside the housing. The fan assembly can drive indoor air into the housing, and after exchanging heat with the heat exchanger, the indoor air can flow into the room through the air outlet to heat or cool the room.

[0003] Furthermore, the air conditioner also includes a vertical air guide plate and a horizontal air guide plate. The vertical air guide plate can adjust the airflow direction of the air outlet in the left and right directions, and the horizontal air guide plate can adjust the airflow direction of the air outlet in the up and down directions.

[0004] However, due to slight differences in the air guiding effect of different blades in the fan assembly, coupled with the influence of components such as the longitudinal and transverse air guides, uneven airflow speed can easily occur. This can lead to problems such as localized areas with no airflow and localized areas with large airflow at the air outlet. Furthermore, in high-temperature and high-humidity environments, if the localized area with no airflow is large, warmer air from the environment will replenish it, resulting in condensation on the air guide, leading to a poor user experience. Utility Model Content

[0005] This utility model aims to solve at least one of the technical problems existing in the prior art. Therefore, one objective of this utility model is to provide an air conditioner that utilizes a deflector bar to oscillate the airflow, distributing the airflow to multiple locations at the air outlet. This reduces the area of ​​the windless zone at the air outlet, preventing condensation from forming when external airflow contacts the air guide plate in the windless zone. Furthermore, the structure is simple and easy to implement.

[0006] To achieve the above objectives, an air conditioner is provided according to an embodiment of the present invention. The air conditioner includes: a housing, wherein the housing has an air inlet and an air outlet, and the housing has a communicating accommodating cavity and an air guiding channel, the air guiding channel being adjacent to the air outlet; a heat exchanger, wherein the heat exchanger is disposed in the accommodating cavity and adjacent to the air inlet; and a fan assembly, wherein the fan assembly is at least partially disposed in the air guiding channel, the fan assembly driving indoor air to enter the housing from the air inlet, and the indoor air, after exchanging heat with the heat exchanger, flows sequentially into the room from the air guiding channel and the air outlet. The air conditioner further includes: a longitudinal air guide plate, which is disposed within the air guide channel and adjacent to the air outlet, and is used to adjust the airflow direction of the air outlet in the left-right direction; and a transverse air guide plate, which is rotatably disposed at the air outlet and is used to adjust the airflow direction of the air outlet in the up-down direction; wherein, the air conditioner further includes: a baffle rod, which is disposed within the air guide channel and extends along the left-right direction of the air conditioner, and is adjacent to the air outlet and spaced upstream of the longitudinal air guide plate in the air outlet direction.

[0007] The above technical solution has the following advantages or beneficial effects: By setting a baffle bar in the air guide channel, the baffle bar can be used to turbulently flow the outlet air. Specifically, the baffle bar can cut the outlet airflow into two parts in the vertical direction, allowing the outlet airflow to oscillate and swing along the baffle bar. The oscillation process changes the original airflow direction, thereby increasing the degree of turbulence. This allows the outlet airflow to be better dispersed to multiple positions at the air outlet, thus reducing the area of ​​the windless zone. This prevents external airflow from contacting the air guide plate in the windless zone and generating condensation, thereby avoiding condensation on the longitudinal and transverse air guide plates. Furthermore, the baffle bar has a simple structure, is easy to assemble, does not excessively increase the cost of the air conditioner, and is easy to implement.

[0008] According to some embodiments of the present invention, the housing is provided with: a front volute tongue; a rear volute shell, the rear volute shell being located behind the front volute tongue, and the rear volute shell and the front volute tongue jointly defining the air guide channel, the rear volute shell being provided with an air guide surface, and the turbulence rod being provided on the rear volute shell and spaced apart from the air guide surface.

[0009] The above technical solution has the following advantages or beneficial effects: it can avoid positional interference between the baffle rod and the air guide surface, so as to fix the baffle rod to the rear volute. Moreover, there is a gap between the baffle rod and the air guide surface, and the part of the airflow cut by the baffle rod in the vertical direction can flow between the baffle rod and the air guide surface. Thus, the baffle rod can be used to divide and turbulent the airflow, so as to effectively reduce the range of the windless area at the air outlet and prevent the external airflow from contacting the air guide plate and generating condensate.

[0010] According to some embodiments of the present invention, at least one end of the spoiler rod in the length direction is provided with a positioning boss, and the side wall of the housing is provided with a positioning groove, the positioning boss extending into the positioning groove.

[0011] The above technical solution has the following advantages or beneficial effects: it can not only pre-position the assembly of the spoiler and the housing, which helps to simplify the assembly steps of the spoiler and the housing, but also provide auxiliary fixation for the spoiler and the housing, preventing the spoiler from shifting position, so that the spoiler is stably fixed to the housing and the connection is more reliable.

[0012] According to some embodiments of the present invention, at least one end of the spoiler rod in the length direction is provided with a first connecting hole, and the side wall of the housing is provided with a second connecting hole, and the first connecting hole and the second connecting hole are connected by fasteners.

[0013] The above technical solution has the following advantages or beneficial effects: By using fasteners to connect the spoiler rod and the housing, the connection stability between the spoiler rod and the housing can be improved, so that the spoiler rod is more stably fixed to the housing and the spoiler rod is less likely to shift position. In this way, the spoiler rod can be used to better turbulent the airflow at the outlet, so as to effectively reduce the windless area of ​​the air outlet and thus better prevent the external airflow from condensing on the air guide plate.

[0014] According to some embodiments of the present invention, the housing is provided with a fixed bracket, the fixed bracket being adjacent to the middle part of the length direction of the housing, the fixed bracket having a fixing hole, and the deflector rod passing through and fixed in the fixing hole.

[0015] The above technical solution has the following advantages or beneficial effects: by adding a fixed bracket to fix the middle part of the baffle rod, the two ends of the baffle rod can be fixed to the side wall of the shell respectively, and the fixed bracket can fix and support the middle part of the baffle rod, which further improves the fixing stability of the baffle rod. The baffle rod is less likely to shift position or deform, so that the baffle rod can better divide and turbulent the airflow.

[0016] According to some embodiments of the present invention, the air conditioner further includes: a driving component, the driving component being fixed inside the housing, the deflector being rotatably fixed to the housing, and the driving component being connected to the deflector to drive the deflector to rotate.

[0017] The above technical solution has the following advantages or beneficial effects: by using a driving component to drive the deflector to rotate, when the airflow comes into contact with the rotating deflector, the deflector can better disperse the airflow, that is, it can improve the deflection effect of the deflector, thereby allowing the airflow to be better dispersed to multiple positions at the air outlet, further reducing the windless area at the air outlet, which can better prevent external airflow from contacting the air guide plate and causing condensation.

[0018] According to some embodiments of the present invention, the transverse air guide plate includes: a body portion; a flow guide portion, wherein the flow guide portion is disposed on one side of the body portion in the width direction, and when the transverse air guide plate opens the air outlet, the flow guide portion is located on the side of the body portion facing the air guide channel; wherein the flow guide portion extends along the length direction of the transverse air guide plate, and the outer contour of the cross-section of the flow guide portion is arc-shaped.

[0019] The above technical solution has the following advantages or beneficial effects: by constructing the outer contour of the cross-section of the guide section as an arc, the airflow can flow along the guide section to the main body, so that the airflow flows along the horizontal guide plate. In this way, the airflow can wrap around the horizontal guide plate to avoid the external airflow from contacting the horizontal guide plate and causing condensation.

[0020] According to some embodiments of the present invention, the extension dimension of the flow guide part along the width direction of the transverse air guide plate is D1, the maximum outer diameter of the flow guide part is D2, and the thickness of the body part is T; wherein, D1 and D2 satisfy: D1≥D2×3 / 5; and / or, D2 and T satisfy: D2>T.

[0021] The above technical solution has the following advantages or beneficial effects: This allows the extension dimension D1 of the guide section along the width direction of the transverse guide plate to be larger, so as to better utilize the guide section to guide the airflow to the main body, so that the airflow adheres well to the surface of the main body and flows along the main body, and the airflow is not easy to separate from the transverse guide plate, so as to more effectively avoid the external airflow from contacting the transverse guide plate and generating condensation.

[0022] According to some embodiments of the present invention, the body portion includes: a first straight segment arranged along its width direction, the first straight segment having a straight cross-section extending in a straight line, and the guide portion being disposed on one side of the first straight segment in the width direction; an arc-shaped segment connected to the other side of the first straight segment in the width direction, and the arc-shaped segment having an arc-shaped cross-section extending in an arc; and a second straight segment connected to the side of the arc-shaped segment away from the first straight segment in the width direction, and the second straight segment having a straight cross-section extending in a straight line.

[0023] The above technical solution has the following advantages or beneficial effects: As a result, the airflow guided by the guide section can flow along the first straight section to the arc section, and can flow along the arc section to the second straight section, so that the airflow can flow closely to multiple positions of the horizontal guide plate, so as to avoid the airflow separating from the horizontal guide plate and creating a windless area.

[0024] According to some embodiments of the present invention, when the horizontal air guide plate opens the air outlet, it has a position to prevent direct blowing. The rear side wall of the air guide channel is provided with an air guide surface. When the horizontal air guide plate is in the position to prevent direct blowing, the first straight section is parallel to and spaced apart from the air outlet end of the air guide surface, and the second straight section extends horizontally and is coplanar with the lower side of the housing.

[0025] The above technical solution has the following advantages or beneficial effects: the airflow guided by the air guide surface can transition more smoothly to the first straight section, and then flow into the room under the guidance of the horizontal air guide plate. Furthermore, the first straight section is spaced apart from the air outlet end of the air guide surface, so that the lower part of the airflow cut by the horizontal air guide plate can flow between the air guide surface and the horizontal air guide plate, thereby allowing this part of the airflow to adhere to the lower side of the horizontal air guide plate, avoiding the generation of a windless area on the lower side of the horizontal air guide plate, and thus preventing condensation from forming on the lower side of the horizontal air guide plate.

[0026] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0031] In the description of this utility model, "first feature" and "second feature" may include one or more of the features.

[0032] In the description of this utility model, "multiple" means two or more, and "several" means one or more.

[0033] The air conditioner 1 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0034] The up-down direction in the attached diagram represents the up-down direction of air conditioner 1, the left-right direction represents the left-right direction of air conditioner 1, and the front-back direction represents the front-back direction of air conditioner 1.

[0035] like Figures 1-10 As shown, the air conditioner 1 according to an embodiment of the present invention may include a housing 100, which has an air inlet 110 and an air outlet 120. The housing 100 also has a communicating accommodating cavity 130 and an air guide channel 140, with the air guide channel 140 adjacent to the air outlet 120. With this configuration, outdoor air can flow into the housing 100 through the air inlet 110, and the airflow into the housing 100 can flow along the air guide channel 140, and under the guidance of the air guide channel 140, can flow towards the air outlet 120, and then flow into the room through the air outlet 120.

[0036] The air conditioner 1 may include a heat exchanger located in the housing 130 and adjacent to the air inlet 110. Air flowing into the housing 100 from the air inlet 110 can flow to the heat exchanger and exchange heat. The air after heat exchange can then flow along the air guide 140 to the air outlet 120 and flow into the room through the air outlet 120 to heat or cool the room.

[0037] The air conditioner 1 may include a fan assembly, which is at least partially disposed within the air guide duct 140. The fan assembly drives indoor air into the housing 100 through the air inlet 110, and after exchanging heat with the heat exchanger, the indoor air flows into the room sequentially through the air guide duct 140 and the air outlet 120. For example, the fan assembly may be a cross-flow fan, which can drive indoor air into the housing 100 through the air inlet 110. That is, the fan assembly can increase the airflow velocity, thereby increasing the air intake volume of the air inlet 110, which in turn increases the airflow rate for heat exchange with the heat exchanger, resulting in higher heat exchange efficiency.

[0038] The air conditioner 1 may also include a longitudinal air guide plate 200, which is disposed within the air guide channel 140 and adjacent to the air outlet 120. The longitudinal air guide plate 200 is used to adjust the airflow direction of the air outlet 120 in the left-right direction. Multiple longitudinal air guide plates 200 may be present, and they may be arranged at intervals along the length of the air outlet 120. By rotating the longitudinal air guide plate 200, the airflow can be guided into the room at different angles in the left-right direction. This not only avoids direct airflow but also allows adjustment of the left-right airflow angle as needed, thereby expanding the airflow range in the left-right direction and enabling a more even distribution of airflow into the room.

[0039] The air conditioner 1 may also include a horizontal air guide plate 300, which is rotatably disposed at the air outlet 120 and used to adjust the airflow direction of the air outlet 120 in the vertical direction. The horizontal air guide plate 300 can extend in the left-right direction. By rotating the horizontal air guide plate 300, the airflow can be guided into the room at different angles in the vertical direction. This not only avoids direct airflow but also allows adjustment of the airflow angle in the vertical direction as needed, thereby expanding the airflow range in the vertical direction and enabling more even distribution of the airflow into the room. Furthermore, the horizontal air guide plate 300 can control the opening and closing of the air outlet 120. When the air conditioner 1 is turned on, the horizontal air guide plate 300 can be rotated to open the air outlet 120 so that the airflow can flow into the room through the air outlet 120. When the air conditioner 1 is turned off, the horizontal air guide plate 300 can be rotated to close the air outlet 120 to prevent dust and impurities from flowing into the housing 100 and to ensure the cleanliness of the air conditioner 1.

[0040] The air conditioner 1 may also include a deflector bar 400, the cross-sectional shape of which may be circular, elliptical or rhomboid, but is not limited thereto.

[0041] Specifically, the deflector bar 400 is disposed within the air guide channel 140 and extends along the left and right direction of the air conditioner 1. The deflector bar 400 is adjacent to the air outlet 120 and is spaced upstream of the longitudinal air guide plate 200 in the air outlet direction.

[0042] The spoiler bar 400 is located upstream of the longitudinal air guide plate 200, meaning that along the flow direction of the airflow, the airflow will first flow through the spoiler bar 400 and then through the longitudinal air guide plate 200.

[0043] Therefore, when the airflow generated by the operation of the fan assembly flows along the air guide channel 140 to the air outlet 120, it can first flow through the baffle bar 400, and then flow sequentially to the longitudinal air guide plate 200 and the transverse air guide plate 300. Under the guidance of the longitudinal air guide plate 200 and the transverse air guide plate 300, the airflow then flows into the room through the air outlet 120.

[0044] By installing a baffle rod 400 within the air guide channel 140, the baffle rod 400 can turbulently control the airflow passing through it. Specifically, the baffle rod 400 can cut the airflow into two parts in the vertical direction, allowing the airflow to oscillate and swing along the baffle rod 400. This oscillation changes the original airflow direction, increasing the turbulence and enabling the airflow to be better dispersed to multiple locations on the air outlet 120. This reduces the area of ​​the windless zone, preventing condensation from forming when external airflow comes into contact with the air guide plates in the windless zone. Consequently, condensation is avoided on the longitudinal air guide plate 200 and the transverse air guide plate 300. Furthermore, the baffle rod 400 has a simple structure, is easy to assemble, and does not excessively increase the cost of the air conditioner 1, making it easy to implement.

[0045] Thus, the air conditioner 1 according to the present utility model embodiment can use the deflector bar 400 to oscillate the airflow, so that the airflow is distributed to multiple positions of the air outlet 120, thereby reducing the range of the windless area generated at the air outlet 120, avoiding the external airflow from contacting the air guide plate in the windless area and generating condensation, and the structure is simple and easy to implement.

[0046] In some specific embodiments of this utility model, such as Figure 2 and Figure 5 As shown, the housing 100 is provided with a front volute tongue 150 and a rear volute 160. The rear volute 160 is located behind the front volute tongue 150, and the rear volute 160 and the front volute tongue 150 together define the air guide channel 140. The rear volute 160 is provided with an air guide surface 161, and the baffle rod 400 is provided on the rear volute 160 and spaced apart from the air guide surface 161.

[0047] The air guide surface 161 of the rear volute 160, which is also the windward surface, is spaced apart from the air guide surface 161 by the deflector bar 400. This avoids positional interference between the deflector bar 400 and the air guide surface 161, making it easier to fix the deflector bar 400 to the rear volute 160. Moreover, there is a gap between the deflector bar 400 and the air guide surface 161, so that part of the airflow cut by the deflector bar 400 in the vertical direction can flow between the deflector bar 400 and the air guide surface 161. This allows the deflector bar 400 to divide and turbulent the airflow, effectively reducing the area of ​​no wind at the air outlet and preventing external airflow from contacting the air guide plate and generating condensation.

[0048] In some specific embodiments of this utility model, such as Figure 7 and Figure 10 As shown, at least one end of the spoiler rod 400 in the length direction is provided with a positioning boss 410, and the side wall of the housing 100 is provided with a positioning groove 181, with the positioning boss 410 extending into the positioning groove 181.

[0049] By setting the positioning groove 181 and positioning boss 410 for positioning and engagement, not only can the assembly of the spoiler 400 and the housing 100 be pre-positioned, which helps to simplify the assembly steps of the spoiler 400 and the housing 100, but also the spoiler 400 and the housing 100 can be auxiliaryly fixed to prevent the spoiler 400 from shifting position, so that the spoiler 400 is stably fixed to the housing 100 and the connection is more reliable.

[0050] One end of the spoiler rod 400 along its length can be provided with a positioning boss 410, and the other end of the spoiler rod 400 can be provided with a larger stop. In this case, a through hole can be constructed on one side wall of the housing 100. When assembling the spoiler rod 400 and the base 180, the end with the positioning boss 410 can pass through the through hole and stop in the positioning groove 181 on the other side, and the stop can stop outside the through hole, thereby realizing the assembly of the spoiler rod 400 and the housing 100.

[0051] Alternatively, positioning bosses 410 can be provided at both ends of the spoiler 400 along its length, and positioning grooves 181 can be provided on the opposite side walls of the housing 100. During assembly, the positioning boss 410 at one end of the spoiler 400 can be assembled into the positioning groove 181 on one side first, and then the positioning boss 410 at the other end of the spoiler 400 can be assembled into the positioning groove 181 on the other side by using the slight deformation of the housing 100, so as to realize the assembly of the spoiler 400 and the housing 100.

[0052] In some specific embodiments of this utility model, such as Figure 10 As shown, at least one end of the spoiler rod 400 in the length direction is provided with a first connection hole (not shown in the figure), and the side wall of the housing 100 is provided with a second connection hole 182. The first connection hole and the second connection hole 182 are connected by fasteners.

[0053] The provision that at least one end of the spoiler rod 400 along its length has a first connecting hole means that the first connecting hole can be provided at one end of the spoiler rod 400 along its length, or the first connecting hole can be provided at both ends of the spoiler rod 400 along its length.

[0054] For example, the first connecting hole can be provided on the end face of the positioning boss 410, and the first connecting hole can extend along the axial direction of the spoiler rod 400. The second connecting hole 182 can be provided at the bottom of the positioning groove 181. The fastener can be a bolt, but is not limited to it.

[0055] This configuration, by using fasteners to connect the spoiler rod 400 and the housing 100, can improve the connection stability between the spoiler rod 400 and the housing 100, making the spoiler rod 400 more stably fixed to the housing 100. The spoiler rod 400 is less prone to positional displacement, and thus can be used to better turbulentize the airflow at the outlet, effectively reducing the range of the windless area at the air outlet 120, thereby better preventing condensation of external airflow on the air guide plate.

[0056] In some specific embodiments of this utility model, such as Figures 7-9 As shown, a fixed bracket 170 is provided inside the housing 100. The fixed bracket 170 is located near the middle of the length direction of the housing 100. The fixed bracket 170 is provided with a fixing hole 171, and the baffle rod 400 passes through and is fixed in the fixing hole 171.

[0057] The fixed bracket 170 can be integrally formed with the housing 100, and the fixed bracket 170 can be integrally formed with the bracket connecting the transverse air guide plate 300. This simplifies the structure of the bracket, helps to reduce the number of parts, and improves the structural strength of the fixed bracket 170.

[0058] By adding a fixed bracket 170 to fix the middle part of the baffle rod 400, both ends of the baffle rod 400 can be fixed to the side wall of the housing 100 respectively, and the fixed bracket 170 can fix and support the middle part of the baffle rod 400, which further improves the fixing stability of the baffle rod 400, so that the baffle rod 400 is more stably fixed to the housing 100, and the baffle rod 400 is less likely to shift position or deform. This allows the baffle rod 400 to better divide and turbulent the airflow at the outlet, so as to effectively reduce the windless area of ​​the air outlet 120 and prevent the external airflow from contacting the air guide plate in the windless area and generating condensation.

[0059] In some other specific embodiments of this utility model, the air conditioner 1 may also include a driving component (not shown in the figure), the driving component is fixed inside the housing 100, the deflector 400 is rotatably fixed to the housing 100, and the driving component is connected to the deflector 400 in a transmission connection to drive the deflector 400 to rotate.

[0060] The driving component can be a motor.

[0061] In other words, in this embodiment, the deflector bar 400 can be driven to rotate by a driving component. When the airflow comes into contact with the rotating deflector bar 400, the deflector bar 400 can better disperse the airflow, that is, it can improve the deflection effect of the deflector bar 400. This allows the airflow to be better dispersed to multiple positions of the air outlet 120, further reducing the windless area at the air outlet 120. This can better prevent external airflow from contacting the air guide plate and causing condensation.

[0062] In some specific embodiments of this utility model, such as Figure 3 and Figure 6 As shown, the horizontal air guide plate 300 may include a body part 310. The horizontal air guide plate 300 mainly relies on the body part 310 to guide the airflow. By adjusting the angle of the body part 310, the airflow can be delivered at different angles in the vertical direction.

[0063] Additionally, the transverse air guide plate 300 may include a guide portion 320, which is located on one side of the main body 310 in the width direction. When the air outlet 120 of the transverse air guide plate 300 is opened, the guide portion 320 is located on the side of the main body 310 facing the air guide channel 140. That is, when the air outlet 120 of the transverse air guide plate 300 is opened, the guide portion 320 is closer to the inner side of the housing 100, and the airflow can first contact the guide portion 320 before flowing towards the main body 310.

[0064] The guide section 320 extends along the length of the transverse guide plate 300, and the outer contour of the cross section of the guide section 320 is arc-shaped.

[0065] It should be noted that fluids (such as air or liquid) tend to adhere to the boundaries of adjacent curved or inclined surfaces during flow and continue to flow along the shape of the surface. By making the outer contour of the cross-section of the guide section 320 arc-shaped, the guide section 320 can be used as an airflow inducing structure, so that the exhaust airflow adheres to the surface of the guide section 320 and flows along the surface of the guide section 320.

[0066] Therefore, when the horizontal air guide plate 300 opens the air outlet 120, the airflow, after being turbulent by the deflector bar 400, flows towards the horizontal air guide plate 300 under the guidance of the vertical air guide plate 200. At this time, the airflow tends to adhere to the arc-shaped surface of the guide section 320 and can flow along the guide section 320 towards the main body 310, and then be guided into the room by the main body 310. This arrangement allows the airflow to flow along the horizontal air guide plate 300, thereby preventing the tail of the horizontal air guide plate 300 from separating from the airflow. That is, the airflow can wrap around the horizontal air guide plate 300 to prevent external airflow from contacting the horizontal air guide plate 300 and causing condensation. Furthermore, this can improve the air guiding effect of the horizontal air guide plate 300, thereby improving the control accuracy of the air outlet angle of the air conditioner 1 and providing a better user experience.

[0067] Furthermore, such as Figure 6 As shown, the extension dimension of the flow guide 320 along the width direction of the transverse air guide plate 300 is D1, the maximum outer diameter of the flow guide 320 is D2, and the thickness of the body part 310 is T. Wherein, D1 and D2 satisfy: D1≥D2×3 / 5, and / or, D2 and T satisfy: D2>T.

[0068] The maximum outer diameter D2 of the flow guide 320 can be no less than 5 mm. For example, D2 can be 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, or 10 mm. Furthermore, the outer contour of the cross-section of the flow guide 320 can be an arc, by making D1 ≥ D2 × 3 / 5, that is, the outer contour of the cross-section of the flow guide 320 is a superior arc.

[0069] In other words, the extension dimension D1 of the guide section 320 along the width direction of the transverse guide plate 300 cannot be too small. If D1 is too small, the outlet airflow cannot adhere well to the surface of the guide section 320, and the outlet airflow cannot flow along the guide section 320 to the main body 310. The air guiding effect of the transverse guide plate 300 will decrease, and the outlet airflow will easily separate from the transverse guide plate 300, which will cause the outside airflow to come into contact with the transverse guide plate 300 in the windless area and produce condensation. Therefore, D1 cannot be less than D2×3 / 5.

[0070] For example, D1 can be D2×3 / 5, D2×7 / 10, D2×4 / 5, D2×9 / 10 or D2.

[0071] Preferably, D1 ≥ D2 × 4 / 5, which allows the extension dimension D1 of the guide section 320 along the width direction of the transverse guide plate 300 to be larger, so as to better utilize the guide section 320 to guide the outlet airflow to the body section 310, so that the outlet airflow adheres well to the surface of the body section 310 and flows along the body section 310, thereby improving the guiding effect of the transverse guide plate 300 on the outlet airflow, and the outlet airflow is less likely to separate from the transverse guide plate 300, so as to more effectively avoid the external airflow from contacting the transverse guide plate 300 and generating condensation.

[0072] In addition, D2 and T satisfy the condition: D2 > T.

[0073] In other words, the maximum outer diameter D2 of the guide section 320 cannot be too small. If D2 is too small and less than T, a stepped structure will be formed at the transition between the guide section 320 and the main body 310. The airflow guided by the guide section 320 will collide with the end of the main body 310. As a result, the airflow cannot flow smoothly along the main body 310, the guiding effect of the transverse guide plate 300 will decrease, and the outside airflow will come into contact with the transverse guide plate 300 and produce condensation. Therefore, D2 cannot be less than T.

[0074] In some specific embodiments of this utility model, such as Figure 3 and Figure 6 As shown, the body portion 310 includes a first straight segment 311, an arc-shaped segment 312, and a second straight segment 313 arranged along its width direction.

[0075] The first straight segment 311 has a straight cross-section that extends in a straight line, and the guide portion 320 is provided on one side of the width direction of the first straight segment 311. The arc-shaped segment 312 is connected to the other side of the width direction of the first straight segment 311, and the cross-section of the arc-shaped segment 312 extends in an arc shape. The second straight segment 313 is connected to the side of the arc-shaped segment 312 away from the first straight segment 311 in the width direction, and the cross-section of the second straight segment 313 extends in a straight line.

[0076] In other words, the transverse air guide plate 300 may include four parts: a guide section 320, a first straight section 311, an arc-shaped section 312, and a second straight section 313. The first straight section 311 may be located between the guide section 320 and the arc-shaped section 312, and the second straight section 313 is connected to the side of the arc-shaped section 312 away from the first straight section 311. When the transverse air guide plate 300 closes the air outlet 120, the outer side of the end of the second straight section 313 away from the arc-shaped section 312 can fit tightly with the face shield 190.

[0077] Therefore, the airflow guided by the guide section 320 can flow along the first straight section 311 to the arc-shaped section 312, and then along the arc-shaped section 312 to the second straight section 313, so that the airflow can closely adhere to multiple positions of the transverse guide plate 300, thus preventing the airflow from separating from the transverse guide plate 300 and creating a windless area. Furthermore, the cross-section of the arc-shaped section 312 extends in an arc shape, which allows the airflow to transition more smoothly from the first straight section 311 to the second straight section 313, thereby allowing the airflow to better conform to the surface of the transverse guide plate 300 and preventing condensation from the external airflow contacting the transverse guide plate.

[0078] Furthermore, such as Figure 5 and Figure 6 As shown, when the horizontal air guide plate 300 opens the air outlet 120, it has a position to prevent direct blowing. The rear side wall of the air guide channel 140 is provided with an air guide surface 161. When the horizontal air guide plate 300 is in the position to prevent direct blowing, the first straight section 311 is parallel to and spaced apart from the air outlet end of the air guide surface 161, and the second straight section 313 extends horizontally and is coplanar with the lower side of the housing 100.

[0079] The air outlet end of the air guide surface 161 refers to the end of the air guide surface 161 that is close to the air outlet 120 along the air outlet direction of the airflow.

[0080] When the transverse air guide plate 300 is in the anti-blowing position, the first straight section 311 is arranged parallel to the air outlet end of the air guide surface 161. This allows the airflow guided by the air guide surface 161 to transition more smoothly onto the first straight section 311, and then flow into the room under the guidance of the transverse air guide plate 300. Furthermore, the first straight section 311 and the air outlet end of the air guide surface 161 are spaced apart, so that the lower half of the airflow cut by the transverse air guide plate 300 can flow between the air guide surface 161 and the transverse air guide plate 300. This allows this part of the airflow to adhere to the lower side of the transverse air guide plate 300, avoiding the creation of a windless area on the lower side of the transverse air guide plate 300, thus preventing condensation on the lower side of the transverse air guide plate 300.

[0081] Furthermore, when the transverse air guide plate 300 is in the anti-blowing position, the second straight section 313 is coplanar with the lower side of the housing 100; that is, when the transverse air guide plate 300 is in the anti-blowing position, the second straight section 313 extends horizontally. This arrangement not only improves the aesthetic appearance of the air conditioner 1 when the transverse air guide plate 300 is open, but also allows the second straight section 313 to better guide the airflow. Compared to the related art where the end of the transverse air guide plate is curved upwards, the end of the transverse air guide plate 300 in this embodiment of the present invention has a better fit with the airflow, thereby better preventing condensation from forming when the external airflow comes into contact with the second straight section 313.

[0082] Furthermore, when the transverse air guide plate 300 is in the anti-direct-blow position, the distance between the first straight section 311 and the air outlet end of the air guide surface 161 can be L, and L ≥ 10mm. For example, L can be 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, 16mm, 17mm, 18mm, 19mm, or 20mm. That is to say, the distance L between the first straight section 311 and the air outlet end of the air guide surface 161 cannot be too small. If L is too small, the airflow may not be able to pass smoothly between the first straight section 311 and the air guide surface 161, and the airflow on the lower side of the first straight section 311 will be less, which will easily cause the external airflow to come into contact with the lower side of the transverse air guide plate 300 and produce condensation. Therefore, L cannot be less than 10mm.

[0083] Other components and operations of the air conditioner 1 according to the embodiments of the present invention are known to those skilled in the art and will not be described in detail here.

[0084] The air conditioner 1 of this invention performs a refrigeration cycle by using a compressor, a condenser, an expansion valve, and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplies refrigerant to the conditioned and heat-exchanged air.

[0085] The compressor compresses refrigerant gas under high temperature and pressure and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0086] The expansion valve expands the high-temperature, high-pressure liquid refrigerant condensed in the condenser into a low-pressure liquid refrigerant. The evaporator evaporates the expanded refrigerant in the expansion valve and returns the low-temperature, low-pressure refrigerant gas to the compressor. The evaporator achieves a cooling effect by utilizing the latent heat of refrigerant evaporation to exchange heat with the material being cooled. Throughout the cycle, air conditioner 1 regulates the temperature and humidity of the indoor space.
