Description

Technical Field

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

[0002] In related technologies, air conditioners typically have air guide components installed in the air outlet duct to achieve air guiding effect in the left and right directions. However, in related technologies, the air guide components are installed in an unreasonable position in the air outlet duct, resulting in a small assembly space for the drive mechanism used to drive the rotation of the air guide components, making the assembly of the drive mechanism more difficult. Therefore, this issue needs to be addressed. Summary of the Invention

[0003] This invention aims to at least solve one of the technical problems existing in the prior art. Therefore, one objective of this invention is to provide an air conditioner in which the plane where the airflow outlet of the air outlet duct is located is the air outlet surface, the width of the air outlet surface in the left-right direction is L2, and the distance D4 between the rotation axis of the air guide component and the air outlet surface in the front-back direction satisfies 0.05*L2≤D4≤0.3*L2. This allows the space between the rotation axis of the air guide component and the air outlet surface to be sufficiently large, so that the first driving mechanism for driving the air guide component can be accommodated within this space. Furthermore, it allows for a more reasonable position of the air guide component in the front-back direction, avoiding interference with the opening and closing door at the air outlet due to the air guide component being too far forward, and also preventing the air guide component from being too far back in the front-back direction, which would weaken its air guiding effect.

The distance D4 between the rotation axis of the air guide component and the air outlet surface in the front-back direction satisfies 0.05*L2≤D4≤0.3*L2. This allows the space between the rotation axis of the air guide component and the air outlet surface to be large enough so that the first driving mechanism for driving the air guide component can be accommodated in this space between the rotation axis of the air guide component and the air outlet surface. It also allows the position of the air guide component in the front-back direction to be more reasonable, avoiding interference with the opening and closing door at the air outlet due to the air guide component being too far forward in the front-back direction, and also avoiding the air guide effect of the air guide component being weakened due to the air guide component being too far back in the front-back direction.

[0033] Embodiments of the present invention are described in detail below. 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 are only used to explain the present invention, and should not be construed as limiting the present invention.

[0034] The following is for reference. Figures 1-8 An air conditioner according to an embodiment of the present invention is described.

[0035] Reference Figures 1-3According to an embodiment of the present invention, an air conditioner includes a housing 1, a heat exchanger assembly 2, an air duct assembly 3, and an air guide component 4. The housing 1 has an air inlet 12 and an air outlet 11, with the air outlet 11 located on the front side of the housing 1. The heat exchanger assembly 2 is disposed inside the housing 1. The air duct assembly 3 is disposed inside the housing 1 and is located between the heat exchanger assembly 2 and the air outlet 11. The air duct assembly 3 includes an air duct volute 31, a fan wheel 32, and an air outlet frame 33. The air duct volute 31 has an air duct 311 inside. At least a portion of the fan wheel 32 is located inside the air duct 311. The air outlet frame 33 is connected to the downstream side of the air duct volute 31 and has an air outlet channel 332 communicating with the air duct 311. The air guide component 4 is rotatably connected to the air outlet frame 33 and is located inside the air outlet channel 332. The rotation axis of the air guide component 4 extends in the vertical direction.

[0036] When the air conditioner is working, the fan wheel 32 drives the airflow through the air inlet 12 into the casing 1 and towards the heat exchanger assembly 2. After heat exchange in the heat exchanger assembly 2, the air flows through the air duct 311 in the duct casing 31 to the air outlet 332, and then is blown out into the room through the air outlet 11 to cool or heat the room. The air guide component 4 is located in the air outlet 332 and can guide the airflow in the air outlet 332, so that the airflow can flow more smoothly to the air outlet 11, reduce the loss during the airflow process, and help improve the air volume. In addition, the air guide component 4 is rotatably connected to the air outlet frame 33, and the direction of the airflow at the air outlet 11 can be adjusted by adjusting the rotation of the air guide component 4.

[0037] Among them, the plane where the air outlet 3322 of the air outlet channel 332 is located is the air outlet surface. The width of the air outlet surface in the left and right direction is L2. The rotation axis of the air guide component 4 is located behind the air outlet surface and the distance between the rotation axis of the air guide component 4 and the air outlet surface in the front and back direction is D4, 0.05*L2≤D4≤0.3*L2.

[0038] For example, D4 ​​can be 0.05*L2, 0.12*L2, 0.22*L2, 0.25*L2, 0.3*L2, etc. With D4≥0.05*L2, the space between the rotation axis of the air guide component 4 and the air outlet surface can be large enough. For example, the drive mechanism used to drive the rotation of the air guide component 4 is the first drive mechanism, which can be easily accommodated in this space between the rotation axis of the air guide component 4 and the air outlet surface. With D4≤0.3*L2, the air guiding effect of the air guide component 4 can be guaranteed, and the distance between the rotation axis of the air guide component 4 and the air outlet surface in the front-to-back direction can be avoided, which would make the position of the air guide component 4 too far back in the front-to-back direction. If the position of the air guide component 4 is too far back in the front-to-back direction, the air guiding effect of the air guide component 4 will be weakened.

[0039] For example, the first drive mechanism is located on the housing 1 and the first drive mechanism and the air guide component 4 are arranged sequentially in the vertical direction. With D4≥0.05*L2, the space between the rotation axis of the air guide component 4 and the air outlet surface can be large enough, which in turn can make the corresponding space on the housing 1 component large enough, so that the assembly space of the first drive mechanism is large enough to accommodate the first drive mechanism. It can also prevent the air guide component 4 from being too far forward. For example, the air outlet 11 is provided with a switch door for opening and closing the air outlet 11. With D4≥0.05*L2, the position of the air guide component 4 can be prevented from being too far forward and interfering with the switch door.

[0040] By using 0.05*L2≤D4≤0.3*L2, the space between the rotation axis of the air guide component 4 and the air outlet surface is large enough so that the first drive mechanism can be accommodated in this space, and the air guiding effect of the air guide component 4 can be well guaranteed.

[0041] According to the air conditioner of the present invention, the plane where the air outlet 3322 of the air outlet channel 332 is located is the air outlet surface. The width of the air outlet surface in the left-right direction is L2. The distance D4 between the rotation axis of the air guide component 4 and the air outlet surface in the front-back direction satisfies 0.05*L2≤D4≤0.3*L2. This allows the space between the rotation axis of the air guide component 4 and the air outlet surface to be large enough so that the first driving mechanism used to drive the air guide component 4 can be accommodated in this space between the rotation axis of the air guide component 4 and the air outlet surface. It also allows the position of the air guide component 4 in the front-back direction to be more reasonable, avoiding interference with the opening and closing door at the air outlet 11 due to the position of the air guide component 4 being too far forward in the front-back direction, and also avoiding the weakening of the air guiding effect of the air guide component 4 due to the position of the air guide component 4 being too far back in the front-back direction.

[0042] Reference Figures 2-4 According to some embodiments of the present invention, an avoidance groove 335 is formed on the inner wall of the air outlet channel 332 to avoid the air guide component 4. The avoidance groove 335 can be used to avoid the air guide component 4 so that the air guide component 4 can rotate more smoothly and avoid interference between the air guide component 4 and the inner wall of the air outlet channel 332.

[0043] By ensuring D4 ≤ 0.3 * L2, the space between the rotation axis of the air guide component 4 and the air outlet surface can be prevented from being too large. If this space is too large, the overall size of the air guide component 4 will be too large, which in turn will cause the clearance groove 335 used to avoid the air guide component 4 to be too large. If the clearance groove 335 is too large, the flow cross section of the air outlet channel 332 will change too abruptly, thereby causing a surge phenomenon due to the sudden change in airflow. By ensuring D4 ≤ 0.3 * L2, the change in the flow cross section of the air outlet channel 332 can be reduced, thereby reducing the surge phenomenon caused by the sudden change in airflow.

[0044] Optionally, refer to Figure 3 The air outlet duct 332 extends to the left at an angle from back to front. The air duct volute 31 includes a front volute tongue 312, which is located on the front side of the impeller 32. The wall of the front volute tongue 312 facing the air duct 311 includes a first volute tongue wall surface 3121 and a second volute tongue wall surface 3122 arranged at an angle. The second volute tongue wall surface 3122 is connected to the downstream side of the first volute tongue wall surface 3121 and includes a first air duct profile 3123 that is planar.

[0045] The air outlet duct 332 has a second air duct profile 333 that is disposed opposite to the second volute tongue wall 3122. The diameter of the impeller 32 is D. A circle with the center of the impeller 32 as the center and a diameter of 1.45D is obtained as the first reference circle. The intersection of the first reference circle and the first air duct profile 3123 is the intersection point A. A perpendicular line g is drawn with the foot of the perpendicular from the intersection point A. The intersection of the perpendicular line g and the second air duct profile 333 is the intersection point B. The line segment formed by the line connecting the intersection point A and the intersection point B is the line segment AB. The length of the line segment AB is L1.

[0046] Reference Figure 2 and Figure 3 According to some embodiments of the present invention, the duct volute 31 includes a front volute tongue 312, which is located on the front side of the impeller 32. The wall surface of the front volute tongue 312 facing the duct 311 includes a first volute tongue wall surface 3121 and a second volute tongue wall surface 3122 arranged at an angle. The second volute tongue wall surface 3122 is connected to the downstream side of the first volute tongue wall surface 3121 and includes a first duct profile 3123 that is planar. The air outlet duct 332 has a second duct profile 333 that is arranged opposite to the second volute tongue wall surface 3122. The diameter of the impeller 32 is D, and the circle obtained with the center of the impeller 32 as the center and xD as the diameter is the first parameter. Let x ≤ 1.55. The intersection point of the first reference circle and the first air duct surface 3123 is the intersection point A. A perpendicular line g is drawn with the foot of the perpendicular from the intersection point A. The intersection point of the perpendicular line g and the second air duct surface 333 is the intersection point B. The line segment formed by the line connecting the intersection points A and B is the line segment AB, and the length of the line segment AB is L1. In the horizontal direction, the point on the air guide component 4 that is farthest from the rotation axis of the air guide component 4 is the point C. The circle obtained with the rotation center of the air guide component 4 as the center and passing through point C is the second reference circle, and the diameter of the second reference circle is D5. 1.1*L1≤D5≤0.95*L2, where L1 is less than L2.

[0047] For example, x can be 1.35, 1.4, 1.45, 1.5, 1.55, etc. By using 1.1*L1≤D5≤0.95*L2, the overall size of the air guide component 4 is moderate, so as to better meet the left and right air guiding effects of the air guide component 4, while avoiding interference between the air guide component 4 and the side wall of the air outlet channel 332 during rotation.

[0048] Reference Figure 2 and Figure 3 According to some embodiments of the present invention, the duct volute 31 includes a front volute tongue 312, which is located on the front side of the impeller 32. The wall surface of the front volute tongue 312 facing the duct 311 includes a first volute tongue wall surface 3121 and a second volute tongue wall surface 3122 arranged at an angle. The second volute tongue wall surface 3122 is connected to the downstream side of the first volute tongue wall surface 3121 and includes a first duct profile 3123 that is planar. The air outlet duct 332 has a second duct profile 333 that is arranged opposite to the second volute tongue wall surface 3122. The diameter of the impeller 32 is D, and a circle with the center of the impeller 32 as the center and a diameter of 1.45D is obtained. The obtained circle is the first reference circle. The intersection of the first reference circle and the first air duct surface 3123 is the intersection point A. A perpendicular line g is drawn with the foot of the perpendicular from the intersection point A. The intersection of the perpendicular line g and the second air duct surface 333 is the intersection point B. The line segment formed by the line connecting the intersection points A and B is the line segment AB. The length of the line segment AB is L1. In the horizontal direction, the point on the air guide component 4 that is farthest from the rotation axis of the air guide component 4 is the point C. The circle obtained with the rotation center of the air guide component 4 as the center and passing through point C is the second reference circle. The diameter of the second reference circle is D5. 1.1*L1≤D5≤0.95*L2, where L1 is less than L2.

[0049] For example, the diameter D5 of the second reference circle can be 1.1*L1, 0.95*L2, etc. By having D5≥1.1*L1, the overall size of the air guide component 4 is large enough to better meet the left and right air guiding effects of the air guide component 4, and avoid the air guide effect of the air guide component 4 being weakened due to the distance between the farthest point on the air guide component 4 and the rotation axis of the air guide component 4 being too small. By having D5≤0.95*L2, the rotation process of the air guide component 4 is smoother, and the overall size of the air guide component 4 is too large, which would cause the air guide component 4 to interfere with the side wall of the air outlet channel 332 during the rotation process.

[0050] By using 1.1*L1≤D5≤0.95*L2, the overall size of the air guide component 4 is moderate, so as to better meet the left and right air guiding effects of the air guide component 4, while avoiding interference between the air guide component 4 and the side wall of the air outlet channel 332 during rotation.

[0051] Reference Figure 7According to some embodiments of the present invention, the air guiding component 4 includes an air guiding grille 45, which includes a plurality of grille ribs 451 spaced apart. The grille ribs 451 extend in a vertical direction, and a guide channel 452 is defined between two adjacent grille ribs 451. The spaced arrangement of the plurality of grille ribs 451 can enhance the overall structural strength of the air guiding grille 45 to a certain extent. The spaced arrangement of the plurality of grille ribs 451 and the definition of the guide channel 452 between two adjacent grille ribs 451 can guide the airflow passing through the air guiding grille 45 and make the airflow distribution more uniform.

[0052] In the description of this invention, "a plurality of" means two or more.

[0053] Reference Figure 3 and Figure 4 According to some embodiments of the present invention, the air guide component 4 has a left air guide position for guiding air to the left front and a right air guide position for guiding air to the right front. In the left air guide position, the air guide grille 45 guides air to the left front, and in the right air guide position, the air guide grille 45 guides air to the right front. When the air guide component 4 is rotated to the left air guide position, the air guide grille 45 can be adjusted to guide the airflow to the left front, and the airflow flows through the guide channel 452 towards the left front of the air outlet 11. When the air guide component 4 is rotated to the right air guide position, the air guide grille 45 can be adjusted to guide the airflow to the right front, and the airflow flows through the guide channel 452 towards the right front of the air outlet 11.

[0054] Reference Figures 2-4 According to some embodiments of the present invention, the air guide component 4 has a left air guide position for guiding air to the left front and a right air guide position for guiding air to the right front. The air guide component 4 also has a front air guide position, in which the air guide component 4 guides air directly forward. In the front air guide position, the airflow direction of the air guide component 4 can be adjusted so that the air guide component 4 guides air directly forward, and the airflow can flow directly forward through the air guide component 4 to meet the user's usage needs.

[0055] Reference Figure 2 According to some embodiments of the present invention, the air guiding component 4 includes an air guiding grille 45, which is rotatably connected to the air outlet frame 33. The air guiding grille 45 includes a plurality of spaced-apart grille ribs 451, which extend in a vertical direction. A guide channel 452 is defined between two adjacent grille ribs 451. In the front air guiding position, the air guiding grille 45 is used to guide airflow directly forward. When the air guiding component 4 is rotated to the front air guiding position, the air guiding direction of the air guiding grille 45 can be adjusted so that the air guiding grille 45 guides airflow directly forward, and the airflow flows directly forward through the guide channel 452.

[0056] Reference Figure 2 According to some embodiments of the present invention, in the front air guide position, the forward-facing side of the air guide component 4 is the front air guide side. In the front air guide position, the maximum distance between the front air guide side and the air outlet surface in the front-rear direction is D3, where -0.1*L2≤D3≤0.45*L2. Specifically, in the front air guide position, when the front air guide side is located in front of the air outlet surface, the distance between the front air guide side and the air outlet surface in the front-rear direction is a positive value; when the front air guide side is located behind the air outlet surface, the distance between the front air guide side and the air outlet surface in the front-rear direction is a negative value.

[0057] For example, D3 can be -0.1*L2, 0.1*L2, 0.2*L2, 0.35*L2, 0.45*L2, etc. By having D3≥-0.1*L2, the overall size of the air guide component 4 can be large enough to better meet the left and right air guiding effects of the air guide component 4, and avoid the air guide component 4's air guiding effect being weakened due to the distance between the front side of the air guide component 4 and the air outlet surface in the front-back direction being too small. By having D3≤0.45*L2, the rotation process of the air guide component 4 is smoother, and the distance between the front side of the air guide component 4 and the air outlet surface in the front-back direction is not too large, which would cause the air guide component 4 to interfere with the side wall of the air outlet channel 332 during rotation.

[0058] By using -0.1*L2≤D3≤0.45*L2, the maximum distance between the front side of the air guide component 4 and the air outlet surface in the front-rear direction is moderate, so as to better satisfy the left and right air guiding effects of the air guide component 4, while avoiding interference between the air guide component 4 and the side wall of the air outlet channel 332 during rotation.

[0059] Reference Figure 6 According to some embodiments of the present invention, the air guiding component 4 includes an air guiding grille 45 and a louver mechanism 46. The air guiding grille 45 is rotatably connected to the air outlet frame 33. The louver mechanism 46 is disposed within the air guiding grille 45 and includes a connecting rod 462 and a plurality of louver blades 461. The plurality of louver blades 461 are arranged in the vertical direction and are rotatably connected to the connecting rod 462 and the air guiding grille 45. The louver mechanism 46 is disposed within the air guiding grille 45, which provides support and protection for the louver mechanism 46. The louver blades 461 are all rotatably connected to the air guiding grille 45 and the connecting rod 462. The rotation amplitude of the louver blades 461 can be adjusted by driving the connecting rod 462 to move, thereby adjusting the airflow direction and flow rate in the vertical direction.

[0060] Reference Figure 5 and Figure 8According to some embodiments of the present invention, the air guide grille 45 includes a plurality of grille ribs 451 spaced apart. The grille ribs 451 extend in the vertical direction, and a guide channel 452 is defined between two adjacent grille ribs 451. At least a portion of the louvers 461 have avoidance notches 464 for avoiding the grille ribs 451. By forming avoidance notches 464 for avoiding the grille ribs 451 on at least a portion of the louvers 461, the internal space of the air guide grille 45 can be fully utilized, making the overall structure of the air guide grille 45 and the louvers 461 compact. It can also reduce or avoid the possibility of interference between the louvers 461 and the air guide grille 45, and can make the area of ​​the louvers 461 larger. A larger area can enhance the guiding effect of the louvers 461 on the airflow, thereby enhancing the overall air guiding effect of the air guide component 4.

[0061] At least some of the louvers 461 have clearance notches 464 for avoiding the grille ribs 451, which may include the following situations: for example, some of the louvers 461 may have clearance notches 464 for avoiding the grille ribs 451; or for example, all the louvers 461 may have clearance notches 464 for avoiding the grille ribs 451.

[0062] Reference Figure 6 According to some embodiments of the present invention, the air outlet frame 33 includes an air outlet frame body 331 and a partition block 334. The air outlet frame body 331 has an air outlet channel 332. The partition block 334 is disposed in the air outlet channel 332 to divide the air outlet channel 332 into multiple air outlet zones arranged in a vertical direction. Each of the multiple air outlet zones is provided with a rotatable air guide component 4. By dividing the air outlet channel 332 into multiple air outlet zones arranged in a vertical direction by the partition block 334, and each air outlet zone is provided with a rotatable air guide component 4, the airflow direction in each air outlet zone can be adjusted respectively.

[0063] Reference Figure 6 According to some embodiments of the present invention, the driving mechanism for driving the air guide component 4 to rotate is a first driving mechanism. There are multiple first driving mechanisms, and the number of first driving mechanisms is the same as the number of air guide components 4, with each first driving mechanism corresponding to a specific air guide component 4. Each first driving mechanism is connected to a corresponding air guide component 4. The first driving mechanism can drive the air guide component 4 to rotate to adjust the direction of airflow at the air outlet 11. By having multiple first driving mechanisms, the number of first driving mechanisms being the same as the number of air guide components 4, and each first driving mechanism corresponding to a specific air guide component 4, the rotation angle of the air guide component 4 in each air outlet area can be driven separately. This allows for independent adjustment of the airflow direction in each air outlet area, making it easier for users to adjust the airflow direction of each air outlet area according to actual conditions, thus improving the user experience.

[0064] For example, the air guide component 4 in each air outlet zone can rotate synchronously; for another example, the air guide component 4 in each air outlet zone can rotate at different speeds in the same direction; for yet another example, the air guide component 4 in each air outlet zone can rotate in different directions.

[0065] Reference Figure 6 According to some embodiments of the present invention, each air guide component 4 includes an air guide grille 45 and a louver mechanism 46. The air guide grille 45 is rotatably connected to the air outlet frame 33. The louver mechanism 46 is disposed on the air guide grille 45. The louver mechanism 46 includes a connecting rod 462 and a plurality of louver blades 461. The plurality of louver blades 461 are arranged in the vertical direction. The plurality of louver blades 461 are rotatably connected to the connecting rod 462 and the louver blades 461 are rotatably connected to the air guide grille 45. The connecting rods 462 in two adjacent air guide components 4 are connected by a connecting column 463. The connecting rods 462 in two adjacent air guide components 4 are rotatably connected to the corresponding connecting column 463. The driving mechanism for driving the movement of the louver mechanism 46 is a second driving mechanism. The louver mechanisms 46 of the plurality of air guide components 4 share a second driving mechanism.

[0066] The second drive mechanism can drive the connecting rod 462 to move, thereby adjusting the rotation amplitude of the louver 461. This allows for adjustment of the airflow direction and flow rate within the air guide grille 45, and further adjustment of the airflow direction at the air outlet 11. Since the connecting rods 462 in adjacent air guide components 4 are rotatably connected to their corresponding connecting columns 463, and the louver mechanisms 46 of multiple air guide components 4 share a single second drive mechanism, one second drive mechanism can drive the louver 461 within multiple air guide components 4 to move synchronously, achieving further adjustment of the airflow direction and flow rate in each air outlet area.

[0067] For example, when the air guide component 4 in adjacent air outlet areas rotates in different directions, the connecting rod 462 in the two adjacent air guide components 4 can be rotatably connected to the corresponding connecting column 463, which can also realize that a second drive mechanism drives the louvers 461 in adjacent air outlet areas to move synchronously.

[0068] Reference Figure 6 According to some embodiments of the present invention, the air guide grille 45 has a first surface 41 on both sides along the vertical direction. The first surface 41 is provided with a rotating shaft 411. The air outlet frame body 331 and the partition block 334 are both provided with rotating holes. The rotating shaft 411 is rotatably accommodated in the corresponding rotating hole. The rotating shaft 411 has a through hole 412 for the connecting post 463 to pass through. The rotating hole facilitates the accommodating of the rotating shaft 411, thereby facilitating the assembly between the air outlet frame 33 and the air guide grille 45, and making the overall structure of the air outlet frame 33 and the air guide grille 45 compact. The through hole 412 facilitates the assembly of the connecting post 463 on the air guide grille 45, and also makes the overall structure of the connecting post 463 and the air guide grille 45 compact.
