Description

Technical Field

[0001] The utility model relates to the technical field of air conditioning equipment, in particular to an air conditioner. Background Art

[0002] In the related art, a wind guiding component is usually arranged in the air outlet passage of an air conditioner to achieve the wind guiding effect in the left-right direction. Due to the structural characteristics of the air duct itself, the air outlet passage usually extends obliquely leftward in the direction from back to front. In this way, when the wind guiding component rotates to the left wind guiding position, the left wind guiding effect can be satisfied, but when the wind guiding component rotates to the right wind guiding position, the right wind guiding effect cannot be well satisfied. Therefore, it remains to be solved. Summary of the Utility Model

[0003] The utility model aims to at least solve one of the technical problems existing in the prior art. For this purpose, an object of the utility model is to provide an air conditioner. By arranging a wind guiding component in the air outlet passage, when the wind guiding component is in the right wind guiding position, the second side and the fourth side of the wind guiding component are arranged in sequence in the direction from the air inlet of the air outlet passage to the air outlet of the air outlet passage. The outer peripheral contour lines of the wind guiding component on the fourth side and the third side are the first contour line, and the outer peripheral contour lines of the wind guiding component on the second side and the third side are the second contour line. The projected length of the first contour line on the reference plane is D1, and the projected length of the second contour line on the reference plane is D2, and D1≥D2. In this way, in the air flow direction, the wind shielding area of the second side of the wind guiding component against the air flow is small, the air volume loss during the air flow process can be reduced, and the air flow can be guided to blow out as much as possible towards the right front of the air outlet to better satisfy the right wind guiding effect.

[0004] The air conditioner according to an embodiment of the utility model includes: a housing, formed with an air inlet and an air outlet, the air outlet being located on the front side of the housing; a heat exchanger assembly, arranged in the housing; and an air duct assembly, arranged in the housing and located between the heat exchanger assembly and the air outlet. The air duct assembly includes an air duct volute, a wind wheel and an air outlet frame. The air duct volute has an air duct inside, at least part of the wind wheel is located in the air duct, the air outlet frame is connected to the downstream side of the air duct volute and has an air outlet passage communicated with the air duct. The air duct volute includes a front volute tongue, the front volute tongue is located on the front side of the wind wheel, and the wall surface of the front volute tongue facing the air duct includes a first volute tongue wall surface and a second volute tongue wall surface arranged at an angle. The second volute tongue wall surface is connected to the downstream side of the first volute tongue wall surface and includes a first air duct profile surface in a plane.

[0005] The air guiding component is rotatably connected to the air outlet frame and is located in the air outlet channel. The rotation axis of the air guiding component extends in the up and down direction. The air guiding component includes a first side, a second side, a third side, and a fourth side sequentially arranged along the circumferential direction of the air guiding component. The circumferential direction of the air guiding component is perpendicular to the up and down direction. The first side and the third side are oppositely arranged, and the second side and the fourth side are oppositely arranged. One of the first side and the third side is the air inlet side of the air guiding component, and the other is the air outlet side of the air guiding component. Wherein, the air guiding component has a left air guiding position for guiding air to the left front and a right air guiding position for guiding air to the right front. When the air guiding component is in the right air guiding position, the second side and the fourth side of the air guiding component are sequentially arranged in the direction from the air inlet of the air outlet channel to the air outlet of the air outlet channel. The outer peripheral contour lines of the air guiding component on the fourth side and the third side are the first contour line, and the outer peripheral contour lines of the air guiding component on the second side and the third side are the second contour line. The projected length of the first contour line on the reference plane is D1, and the projected length of the second contour line on the reference plane is D2, D1≥D2. The reference plane is perpendicular to the first air duct profile.

[0006] According to the air conditioner of the embodiment of the present invention, by providing an air guiding component in the air outlet channel, when the air guiding component is in the right air guiding position, the second side and the fourth side of the air guiding component are sequentially arranged in the direction from the air inlet of the air outlet channel to the air outlet of the air outlet channel.

The projected length of the first contour line on the reference plane is D1, and the projected length of the second contour line on the reference plane is D2, D1≥D2. In this way, in the air flow direction, the wind blocking area of the second side of the air guiding component on the air flow is small, which can reduce the air volume loss during the air flow process, and can guide the air flow to blow out as much as possible towards the right front of the air outlet, so as to better meet the right air guiding effect. In addition, since the air outlet channel extends obliquely leftward in the direction from back to front, when the air guiding component rotates to the left air guiding position, the left air guiding effect can be satisfied. By providing the above air guiding component in the air conditioner, the left air guiding effect and the right air guiding effect can be better satisfied.

[0037] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, in which 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 by referring to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation of the present invention.

[0038] Refer to the following Figures 1 - 7 to describe an air conditioner according to an embodiment of the present utility model.

[0039] Referring to Figures 1 - 3 , the air conditioner according to an embodiment of the present utility model includes a housing 1, a heat exchanger assembly 2, an air duct assembly 3, and a wind guiding member 4. The housing 1 is formed with an air inlet 12 and an air outlet 11. The air outlet 11 is located on the front side of the housing 1. The heat exchanger assembly 2 is disposed in the housing 1. The air duct assembly 3 is disposed in the housing 1 and the air duct assembly 3 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 wind wheel 32, and an air outlet frame 33. An air duct 311 is formed in the air duct volute 31. At least a part of the wind wheel 32 is located in the air duct 311. The air outlet frame 33 is connected to the downstream side of the air duct volute 31 and the air outlet frame 33 has an air outlet passage 332 communicating with the air duct 311. The wind guiding member 4 is rotatably connected to the air outlet frame 33 and the wind guiding member 4 is located in the air outlet passage 332.

[0040] When the air conditioner is operating, the wind wheel 32 can drive the air flow to enter the housing 1 component through the air inlet 12 and flow towards the heat exchanger assembly 2. The air after being heat-exchanged by the heat exchanger assembly 2 can flow towards the air outlet passage 332 through the air duct 311 in the air duct volute 31, and then be blown out through the air outlet 11 to the room to cool or heat the room. The wind guiding member 4 is located in the air outlet passage 332 and can guide the air flow in the air outlet passage 332, enabling the air flow to flow towards the air outlet 11 more smoothly, reducing the loss during the air flow process, and being beneficial to increasing the air volume. Moreover, the wind guiding member 4 is rotatably connected to the air outlet frame 33. By adjusting the rotation amplitude of the wind guiding member 4, the direction of the air flow at the air outlet 11 can be adjusted.

[0041] The air duct volute 31 includes a front volute tongue 312. The front volute tongue 312 is located on the front side of the wind wheel 32. The wall surface 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 the second volute tongue wall surface 3122 includes a first air duct profile surface 3123 in a plane. The rotation axis of the wind guiding member 4 extends in the up-down direction. The wind guiding member 4 can rotate relative to the air outlet frame 33 in the left-right direction to achieve the air guiding effect in the left-right direction.

[0042] The air guiding component 4 includes a first side 41, a second side 42, a third side 43, and a fourth side 44 arranged in sequence along the circumferential direction of the air guiding component 4. The circumferential direction of the air guiding component 4 is perpendicular to the up-down direction. The first side 41 and the third side 43 are oppositely arranged, and the second side 42 and the fourth side 44 are oppositely arranged. One of the first side 41 and the third side 43 is the air inlet side of the air guiding component 4, and the other of the first side 41 and the third side 43 is the air outlet side of the air guiding component 4. Among them, the air guiding component 4 has a left air guiding position for guiding air to the left front and a right air guiding position for guiding air to the right front. When the air guiding component 4 is in the right air guiding position, the second side 42 and the fourth side 44 are arranged in sequence in the direction from the air inlet 3321 of the air outlet passage 332 to the air outlet 3322 of the air outlet passage 332. The outer peripheral contour lines of the air guiding component 4 at the fourth side 44 and the third side 43 are the first contour line, and the outer peripheral contour lines of the air guiding component 4 at the second side 42 and the third side 43 are the second contour line. The projected length of the first contour line on the reference plane is D1, and the projected length of the second contour line on the reference plane is D2, where D1≥D2, and the reference plane is perpendicular to the first air duct profile 3123.

[0043] By adjusting the rotation angle of the air guiding component 4, the air guiding direction of the air flow can be changed. When the air guiding component 4 is in the left air guiding position, the air flow can be guided to blow out towards the left front. When the air guiding component 4 is in the right air guiding position, the air flow can be guided to blow out towards the right front. Since the air outlet passage 332 extends obliquely to the left in the front-to-back direction, it can guide the air flow in the air outlet passage 332 to blow out towards the left front, so that when the air guiding component 4 rotates to the left air guiding position, the left air guiding effect can be better satisfied.

[0044] Taking the first side 41 as the air inlet side of the air guiding component 4 and the third side 43 as the air outlet side of the air guiding component 4 as an example, the air guiding component 4 of the present invention will be described.

[0045] When the air guiding component 4 is in the right air guiding position, the second side 42 and the fourth side 44 are arranged in sequence in the direction from the air inlet 3321 of the air outlet passage 332 to the air outlet 3322 of the air outlet passage 332. The outer peripheral contour lines of the air guiding component 4 on the fourth side 44 and the third side 43 are the first contour line, and the outer peripheral contour lines of the air guiding component 4 on the second side 42 and the third side 43 are the second contour line. The projected length of the first contour line on the reference plane is D1, and the projected length of the second contour line on the reference plane is D2, where D1≥D2. In the air flow direction, the shielding area of the second side 42 of the air guiding component 4 against the air flow can be made smaller, so as to reduce the air volume loss when the air flow passes through the air guiding component 4, thereby enhancing the right air guiding effect of the air guiding component 4. Moreover, the fourth side 44 is located on the side away from the air inlet 3321 of the air outlet passage 332. The shielding area of the fourth side 44 against the air flow is larger, which can reduce the possibility of the air flow flowing out towards the front or the left front, and can also guide the air flow to blow out towards the right front as much as possible, so as to better meet the right air guiding effect of the air guiding component 4.

[0046] For example, when the air conditioner is operating and the air guiding component 4 is in the right air guiding position, the impeller 32 drives the air flow to flow into the casing 1 component through the air inlet 12 and flow towards the heat exchanger assembly 2. The air after being heat exchanged by the heat exchanger assembly 2 flows towards the air duct 311. The air flow in the air duct 311 can flow into the air outlet passage 332 through the air inlet 3321. The air flow in the air outlet passage 332 flows towards the air guiding component 4 through the air outlet 3322. The air flow sequentially flows through the first side 41 and the third side 43 and flows out towards the air outlet 11 and towards the right front to meet the user's usage requirements. Among them, the shielding area of the second side 42 of the air guiding component 4 against the air flow is smaller, which can reduce the air volume loss, so as to better meet the right air guiding effect of the air guiding component 4.

[0047] For the air conditioner according to the embodiment of the present invention, by providing the air guiding component 4 in the air outlet passage 332, when the air guiding component 4 is in the right air guiding position, the second side 42 and the fourth side 44 of the air guiding component 4 are arranged in sequence in the direction from the air inlet 3321 of the air outlet passage 332 to the air outlet 3322 of the air outlet passage 332. And the outer peripheral contour lines of the air guiding component 4 on the fourth side 44 and the third side 43 are the first contour line, and the outer peripheral contour lines of the air guiding component 4 on the second side 42 and the third side 43 are the second contour line. The projected length of the first contour line on the reference plane is D1, and the projected length of the second contour line on the reference plane is D2, where D1≥D2. In this way, in the air flow direction, the wind shielding area of the second side 42 of the air guiding component 4 against the air flow is smaller, which can reduce the air volume loss during the air flow process, and can also guide the air flow to blow towards the right front of the air outlet 11 as much as possible to better meet the right air guiding effect.

[0048] Refer to Figure 2 andFigure 3 According to some embodiments of the present utility model, the air outlet passage 332 has a second air duct profile 333 disposed opposite to the second volute tongue wall surface 3122. The diameter of the impeller 32 is D. A first reference circle is obtained with the center of the impeller 32 as the center and xD as the diameter, where 1.35 ≤ x ≤ 1.55. The intersection point of the first reference circle and the first air duct profile 3123 is intersection point A. A perpendicular line g is drawn with intersection point A as the foot of the perpendicular. The intersection point of the perpendicular line g and the second air duct profile 333 is intersection point B. The line segment formed by connecting intersection point A and intersection point B is line segment AB, and the length of line segment AB is L1, and D1 ≥ 0.45 * L1.

[0049] For example, x can be 1.35, 1.4, 1.45, 1.5, 1.55, etc. By D1 ≥ 0.45 * L1, when the air guiding member 4 is in the right air guiding position, the wind shielding area of the fourth side 44 of the air guiding member 4 can be made large enough to reduce or avoid the possibility of air flow flowing towards the front or the left front, and can better guide the air flow to blow towards the right front, thereby better meeting the right air guiding effect of the air guiding member 4.

[0050] Refer to Figure 2 and Figure 3 According to some embodiments of the present utility model, the air outlet passage 332 has a second air duct profile 333 disposed opposite to the second volute tongue wall surface 3122. The diameter of the impeller 32 is D. A first reference circle is obtained with the center of the impeller 32 as the center and 1.45D as the diameter. The intersection point of the first reference circle and the first air duct profile 3123 is intersection point A. A perpendicular line g is drawn with intersection point A as the foot of the perpendicular. The intersection point of the perpendicular line g and the second air duct profile 333 is intersection point B. The line segment formed by connecting intersection point A and intersection point B is line segment AB, and the length of line segment AB is L1, and D1 ≥ 0.45 * L1. For example, D1 can be 0.45 * L1, 0.55 * L1, 0.65 * L1, 0.7 * L1, 0.85 * L1, etc. By D1 ≥ 0.45 * L1, when the air guiding member 4 is in the right air guiding position, the wind shielding area of the fourth side 44 of the air guiding member 4 can be made large enough to reduce or avoid the possibility of air flow flowing towards the front or the left front, and can better guide the air flow to blow towards the right front, thereby better meeting the right air guiding effect of the air guiding member 4.

[0051] Refer to Figure 2 and Figure 3, according to some embodiments of the present utility model, the air outlet passage 332 has a second air duct profile 333 disposed opposite to the second volute tongue wall surface 3122. The diameter of the impeller 32 is D. A circle obtained with the center of the impeller 32 as the center and xD as the diameter is the first reference circle, where 1.35 ≤ x ≤ 1.55. The intersection point of the first reference circle and the first air duct profile 3123 is intersection point A. A perpendicular line g is drawn with intersection point A as the foot of the perpendicular. The intersection point of the perpendicular line g and the second air duct profile 333 is intersection point B. The line segment formed by connecting intersection point A and intersection point B is line segment AB, and the length of line segment AB is L1, and D2 ≤ 0.8 * L1.

[0052] For example, x can be 1.35, 1.4, 1.45, 1.5, 1.55, etc. By D2 ≤ 0.8 * L1, when the air guiding component 4 is in the right air guiding position, the windward area of the second side 42 of the air guiding component 4 can be made as small as possible to reduce the air volume loss, so that the air flow can flow out towards the right front as much as possible through the air guiding component 4, thereby enhancing the right air guiding effect of the air guiding component 4.

[0053] Refer to Figure 2 and Figure 3 , according to some embodiments of the present utility model, the air outlet passage 332 has a second air duct profile 333 disposed opposite to the second volute tongue wall surface 3122. The diameter of the impeller 32 is D. A circle obtained with the center of the impeller 32 as the center and 1.45D as the diameter is the first reference circle. The intersection point of the first reference circle and the first air duct profile 3123 is intersection point A. A perpendicular line g is drawn with intersection point A as the foot of the perpendicular. The intersection point of the perpendicular line g and the second air duct profile 333 is intersection point B. The line segment formed by connecting intersection point A and intersection point B is line segment AB, and the length of line segment AB is L1, and D2 ≤ 0.8 * L1. For example, D2 can be 0.45 * L1, 0.55 * L1, 0.65 * L1, 0.7 * L1, 0.85 * L1, etc. By D2 ≤ 0.8 * L1, when the air guiding component 4 is in the right air guiding position, the windward area of the second side 42 of the air guiding component 4 can be made as small as possible to reduce the air volume loss, so that the air flow can flow out towards the right front as much as possible through the air guiding component 4, thereby enhancing the right air guiding effect of the air guiding component 4.

[0054] Refer to Figure 4 , according to some embodiments of the present utility model, when the air guiding component 4 is in the left air guiding position, the first side 41 and the third side 43 are arranged in sequence in the direction from the air inlet 3321 to the air outlet 3322. At this time, the first side 41 is the air inlet side, and the third side 43 is the air outlet side. The air flow in the air outlet passage 332 enters from the first side 41 and then directly flows towards the left front through the third side 43 to achieve the left air guiding effect of the air guiding component 4.

[0055] Refer to Figures 2 - 4, according to some embodiments of the present utility model, an avoidance groove 335 for avoiding the air guiding member 4 is formed on the inner wall of the air outlet passage 332. The avoidance groove 335 can be used to avoid the air guiding member 4, so that the air guiding member 4 rotates more smoothly and prevent the air guiding member 4 from interfering with the inner wall of the air outlet passage 332.

[0056] Refer to Figure 2 and Figure 3 , according to some embodiments of the present utility model, the plane where the air flow outlet 3322 is located is the air outlet surface. The width of the air outlet surface in the left - right direction is L2. The rotation axis of the air guiding member 4 is located behind the air outlet surface, and the distance between the rotation axis of the air guiding member 4 and the air outlet surface in the front - back direction is D4, and 0.05*L2 ≤ D4 ≤ 0.3*L2. For example, D4 can be 0.05*L2, 0.12*L2, 0.22*L2, 0.25*L2, 0.3*L2, etc. By D4 ≥ 0.05*L2, the space between the rotation axis of the air guiding member 4 and the air outlet surface can be made large enough. For example, if the driving mechanism for driving the air guiding member 4 to rotate is the first driving mechanism, it is convenient for the first driving mechanism to be accommodated in this part of the space between the rotation axis of the air guiding member 4 and the air outlet surface, and then it is convenient for the first driving mechanism to drive the air guiding member 4 to rotate relative to the air outlet frame 33. By D4 ≤ 0.3*L2, the sudden change of the air flow during the flowing process can be reduced, and the possibility of surging due to excessive sudden change of the air flow can be reduced or avoided.

[0057] For example, the first driving mechanism is arranged on the housing 1, and the first driving mechanism and the air guiding member 4 are arranged in sequence in the up - down direction. By D4 ≥ 0.05*L2, the space between the rotation axis of the air guiding member 4 and the air outlet surface can be made large enough, and then the corresponding space on the housing 1 component can be made large enough to facilitate the accommodation of the first driving mechanism therein, and it can also prevent the air guiding member 4 from being too far forward. For example, there is a switch door for opening and closing the air outlet 11 at the air outlet 11. By D4 ≥ 0.05*L2, it can prevent the air guiding member 4 from being too far forward and interfering with the switch door.

[0058] By D4 ≤ 0.3*L2, it can prevent the space between the rotation axis of the air guiding member 4 and the air outlet surface from being too large. If the space between the rotation axis of the air guiding member 4 and the air outlet surface is too large, the overall size of the air guiding member 4 will be too large, and then the avoidance groove 335 for avoiding the air guiding member 4 will be too large. An overly large avoidance groove 335 will cause too large a sudden change in the flow cross - section of the air outlet passage 332, thus triggering the phenomenon of surging due to air flow mutation. By D4 ≤ 0.3*L2, the sudden change in the flow cross - section of the air outlet passage 332 can be made smaller to reduce the phenomenon of surging due to air flow mutation.

[0059] By 0.05*L2 ≤ D4 ≤ 0.3*L2, the space between the rotation axis of the air guiding component 4 and the air outlet surface is large enough to facilitate the accommodation of the first driving mechanism in this part of the space and reduce the sudden change of air flow.

[0060] Referring to Figure 2 and Figure 3 , according to some embodiments of the present invention, the air outlet channel 332 has a second air duct profile 333 disposed opposite to the second volute tongue wall surface 3122. The diameter of the air wheel 32 is D. The circle obtained with the center of the air wheel 32 as the center and xD as the diameter is the first reference circle, 1.35 ≤ x ≤ 1.55. 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 intersection point A as the foot of the perpendicular. The intersection of the perpendicular line g and the second air duct profile 333 is the intersection point B. The line segment formed by connecting the intersection point A and the intersection point B is the line segment AB. The length of the line segment AB is L1. The plane where the air outlet 3322 is located is the air outlet surface. The width of the air outlet surface in the left-right direction is L2. In the horizontal direction, the point on the air guiding component 4 that is farthest from the rotation axis of the air guiding component 4 is the point C. The circle obtained with the rotation center of the air guiding component 4 as the center and passing through the 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.

[0061] For example, x can be 1.35, 1.4, 1.45, 1.5, 1.55, etc. By 1.1*L1 ≤ D5 ≤ 0.95*L2, the overall size of the air guiding component 4 is moderate, so as to better meet the left air guiding effect and the right air guiding effect of the air guiding component 4, and at the same time avoid interference between the air guiding component 4 and the side wall of the air outlet channel 332 during the rotation process.

[0062] Referring to Figure 2 and Figure 3, according to some embodiments of the present utility model, the air outlet passage 332 has a second air duct profile 333 disposed opposite to the second volute tongue wall surface 3122. The diameter of the impeller 32 is D. A first reference circle is obtained with the center of the impeller 32 as the center and 1.45D as the diameter. The intersection point of the first reference circle and the first air duct profile 3123 is intersection point A. A perpendicular line g is drawn with intersection point A as the foot of the perpendicular. The intersection point of the perpendicular line g and the second air duct profile 333 is intersection point B. The line segment formed by connecting intersection point A and intersection point B is line segment AB. The length of line segment AB is L1. The plane where the air outlet 3322 is located is the air outlet surface. The width of the air outlet surface in the left-right direction is L2. In the horizontal direction, the point on the air guiding component 4 that is farthest from the rotation axis of the air guiding component 4 is point C. A second reference circle is obtained with the rotation center of the air guiding component 4 as the center and passing through point C. The diameter of the second reference circle is D5, and 1.1*L1 ≤ D5 ≤ 0.95*L2, where L1 is less than L2. For example, the diameter D5 of the second reference circle can be 1.1*L1, 0.95*L2, etc. By D5 ≥ 1.1*L1, the overall size of the air guiding component 4 is large enough to better meet the left air guiding effect and the right air guiding effect of the air guiding component 4, and avoid weakening the air guiding effect of the air guiding component 4 on the air flow due to too small a distance between the farthest point on the air guiding component 4 and the rotation axis of the air guiding component 4; by D5 ≤ 0.95*L2, the rotation process of the air guiding component 4 is smoother, and avoid the overall size of the air guiding component 4 being too large and causing interference between the air guiding component 4 and the side wall of the air outlet passage 332 during the rotation process.

[0063] By 1.1*L1 ≤ D5 ≤ 0.95*L2, the overall size of the air guiding component 4 is moderate, so as to better meet the left air guiding effect and the right air guiding effect of the air guiding component 4, and at the same time avoid interference between the air guiding component 4 and the side wall of the air outlet passage 332 during the rotation process.

[0064] Refer to Figure 3 , according to some embodiments of the present utility model, the air guiding component 4 further has a front air guiding position. In the front air guiding position, the air guiding component 4 is used to guide the air forward. In the front air guiding position, the air guiding component 4 can guide the air flow to flow forward to meet the user's usage requirements.

[0065] For example, when the air guiding component 4 is in the front air guiding position, the first side 41 and the third side 43 are arranged in sequence in the front-to-back direction, and the fourth side 44 and the second side 42 are arranged in sequence in the left-to-right direction. At this time, the first side 41 is the air inlet side, and the third side 43 is the air outlet side. The air flow in the air outlet passage 332 enters from the first side 41 and then directly passes through the third side 43 and flows forward to achieve the front air guiding effect of the air guiding component 4.

[0066] Refer to Figure 3 , Figure 5 and Figure 7, according to some embodiments of the present utility model, the air guiding member 4 includes an air guiding grille 45. The air guiding grille 45 is rotatably connected to the air outlet frame 33. The air guiding grille 45 includes a first side 41, a second side 42, a third side 43, and a fourth side 44. The air guiding grille 45 includes a plurality of spaced grille ribs 451. The grille ribs 451 extend in the up and down direction, and a flow guiding channel 452 is defined between two adjacent grille ribs 451. Among them, in the front air guiding position, the air guiding grille 45 is used to guide air straight ahead.

[0067] To a certain extent, the plurality of grille ribs 451 can enhance the overall structural strength of the air guiding grille 45. The plurality of grille ribs 451 are spaced apart, and a flow guiding channel 452 is defined between two adjacent grille ribs 451, which can guide the airflow flowing through the air guiding grille 45 and make the airflow distribution more uniform. When the air guiding member 4 rotates to the front air guiding position, the flow guiding direction of the air guiding grille 45 for the airflow can be adjusted so that the air guiding grille 45 guides air straight ahead, and the airflow flows straight ahead through the flow guiding channel 452.

[0068] Referring to Figure 2 , according to some embodiments of the present utility model, the plane where the air outlet 3322 is located is the air outlet surface. The width of the air outlet surface in the left and right direction is L2. In the front air guiding position, the maximum distance in the front and back direction between the third side 43 and the air outlet surface is D3, and -0.1*L2 ≤ D3 ≤ 0.45*L2. Among them, in the front air guiding position, when the third side 43 is located on the front side of the air outlet surface, the distance in the front and back direction between the third side 43 and the air outlet surface is a positive value; when the third side 43 is located on the rear side of the air outlet surface, the distance in the front and back direction between the third side 43 and the air outlet surface is a negative value.

[0069] For example, D3 can be -0.1*L2, 0.1*L2, 0.2*L2, 0.35*L2, 0.45*L2, etc. By D3 ≥ -0.1*L2, the overall size of the air guiding member 4 can be made large enough to better meet the left air guiding effect and the right air guiding effect of the air guiding member 4, and avoid weakening the air guiding effect of the air guiding member 4 on the airflow due to the too small distance in the front and back direction between the third side 43 and the first side 41; by D3 ≤ 0.45*L2, the rotation process of the air guiding member 4 is made smoother, and avoid the third side 43 of the air guiding member 4 interfering with the side wall of the air outlet channel 332 due to the too large distance in the front and back direction between the third side 43 and the first side 41.

[0070] By -0.1*L2 ≤ D3 ≤ 0.45*L2, the maximum distance in the front and back direction between the third side 43 and the first side 41 of the air guiding member 4 is made appropriate, so as to better meet the left air guiding effect and the right air guiding effect of the air guiding member 4, and at the same time avoid the air guiding member 4 interfering with the side wall of the air outlet channel 332 during the rotation process.

[0071] Reference Figure 2

[0072] Figure 6 Reference Figure 6 and Figure 7

[0073] In the description of the present invention, "a plurality of" means two or more than two.

[0074]

[0074] Reference Figure 6 and Figure 7

[0075] For example, the air guiding components 4 in each air outlet area can rotate synchronously; for another example, the air guiding components 4 in each air outlet area can rotate differentially in the same direction; for still another example, the air guiding components 4 in each air outlet area can rotate in different directions.

[0076]

[0076] Reference Figure 6, according to some embodiments of the present utility model, each air guiding member 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 on the air guiding 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 up and down 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 guiding grille 45. The connecting rods 462 in two adjacent air guiding members 4 are connected by a connecting column 463. The connecting rods 462 in two adjacent air guiding members 4 are rotatably connected to the corresponding connecting column 463. The driving mechanism for driving the louver mechanism 46 to move is a second driving mechanism. The louver mechanisms 46 of the plurality of air guiding members 4 share one second driving mechanism.

[0077] The second driving mechanism can drive the connecting rod 462 to move, thereby adjusting the rotation amplitude of the louver blade 461, and can adjust the flow direction and air flow rate of the air flowing through the air guiding grille 45, and further can adjust the air flow direction at the air outlet 11. By rotatably connecting the connecting rods 462 in two adjacent air guiding members 4 to the corresponding connecting column 463, and the louver mechanisms 46 of the plurality of air guiding members 4 sharing one second driving mechanism, it can be realized that one second driving mechanism drives the louver blades 461 in the plurality of air guiding members 4 to move synchronously, and further adjust the air flow direction and air flow rate in each air outlet area.

[0078] For example, when the air guiding members 4 in adjacent air outlet areas rotate in different directions, by rotatably connecting the connecting rods 462 in two adjacent air guiding members 4 to the corresponding connecting column 463, it can also be realized that one second driving mechanism drives the louver blades 461 in adjacent air outlet areas to move synchronously.

[0079] Refer to Figure 3 , Figure 4 and Figure 7 , according to some embodiments of the present utility model, the air guiding member 4 includes an air guiding grille 45. The air guiding grille 45 includes a plurality of grille ribs 451 arranged at intervals. The grille ribs 451 extend in the up and down direction. A diversion channel 452 is defined between two adjacent grille ribs 451. Among them, in the left air guiding position, the air guiding grille 45 is used to guide air to the left front. In the right air guiding position, the air guiding grille 45 is used to guide air to the right front. When the air guiding member 4 rotates to the left air guiding position, the diversion direction of the air guiding grille 45 for the air can be adjusted so that the air guiding grille 45 guides air to the left front, and the air flows through the diversion channel 452 towards the left front of the air outlet 11; when the air guiding member 4 rotates to the right air guiding position, the diversion direction of the air guiding grille 45 for the air can be adjusted so that the air guiding grille 45 guides air to the right front, and the air flows through the diversion channel 452 towards the right front of the air outlet 11.

[0080] Optionally, at least a part of the louver 461 is located in the air guiding channel 452, which can further adjust the direction of the air flow passing through the air guiding channel 452, and can also make full use of the space inside the air guiding grille 45, so that the area of the louver 461 is relatively large and the overall structure of the louver 461 and the air guiding grille 45 is more compact.

[0081] For example, the louver 461 swings in the up and down direction, and the air guiding grille 45 rotates left and right. The rotation of the louver 461 in the up and down direction can adjust the flow direction of the air flow in the up and down direction, and the rotation of the air guiding grille 45 in the left and right direction can adjust the flow direction of the air flow in the left and right direction, so as to achieve the adjustment effect of the air flow passing through the air guiding component 4 in multiple directions.

[0082] Among them, the situation that at least a part of the louver 461 is located in the air guiding channel 452 may include the following cases: for example, a part of a part of the louver 461 is located in the air guiding channel 452; for another example, a part of all the louvers 461 is located in the air guiding channel 452.

[0083] Next, refer to Figures 1 - 7 to describe an air conditioner according to some embodiments of the present invention.

[0084] Refer to Figures 2 - 4 , in this embodiment, the air conditioner is a split floor-standing air conditioner, which includes an air conditioner indoor unit 100 and an air conditioner outdoor unit. The air conditioner indoor unit 100 includes a housing 1, a heat exchanger assembly 2, an air duct assembly 3, and an air guiding component 4.

[0085] The housing 1 is formed with an air inlet 12 and an air outlet 11. The air outlet 11 is located on the front side of the housing 1. The heat exchanger assembly 2 is arranged in the housing 1. The air duct assembly 3 is arranged in the housing 1 and the air duct assembly 3 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 blower wheel 32, and an air outlet frame 33. The air duct volute 31 has an air duct 311 inside. At least a part of the blower wheel 32 is located in the air duct 311. The air outlet frame 33 is connected to the downstream side of the air duct volute 31 and the air outlet frame 33 has an air outlet channel 332 communicating with the air duct 311. The air outlet channel 332 extends obliquely to the left in the direction from back to front. A relief groove 335 for avoiding the air guiding component 4 is formed on the inner wall of the air outlet channel 332. The air guiding component 4 is rotatably connected to the air outlet frame 33 and the air guiding component 4 is located in the air outlet channel 332.

[0086] The air duct volute 31 includes a front scroll tongue 312. The front scroll tongue 312 is located on the front side of the blower wheel 32. The wall surface of the front scroll tongue 312 facing the air duct 311 includes a first scroll tongue wall surface 3121 and a second scroll tongue wall surface 3122 arranged at an angle. The second scroll tongue wall surface 3122 is connected to the downstream side of the first scroll tongue wall surface 3121 and includes a first air duct profile surface 3123 in a plane.

[0087] The air outlet frame 33 includes an air outlet frame body 331 and a partition block 334. An air outlet channel 332 is formed in the air outlet frame body 331. The partition block 334 is disposed in the air outlet channel 332 to divide the air outlet channel 332 into a plurality of air outlet areas arranged in the up-and-down direction. A rotatable air guiding member 4 is provided in each of the plurality of air outlet areas. The driving mechanism for driving the air guiding member 4 to rotate is a first driving mechanism. There are a plurality of first driving mechanisms, and the number of the first driving mechanisms is the same as that of the air guiding members 4 and they are respectively in one-to-one correspondence. Each first driving mechanism is connected to the corresponding air guiding member 4. The air guiding member 4 includes an air guiding grille 45. The air guiding grille 45 includes a plurality of grille ribs 451 arranged at intervals. The grille ribs 451 extend in the up-and-down direction, and a diversion channel 452 is defined between two adjacent grille ribs 451.

[0088] The rotation axis of the air guiding member 4 extends in the up-and-down direction. The air guiding member 4 includes a first side 41, a second side 42, a third side 43, and a fourth side 44 arranged in sequence along the circumferential direction of the air guiding member 4. The circumferential direction of the air guiding member 4 is perpendicular to the up-and-down direction. The first side 41 and the third side 43 are oppositely arranged, and the second side 42 and the fourth side 44 are oppositely arranged. One of the first side 41 and the third side 43 is the air inlet side of the air guiding member 4 and the other is the air outlet side of the air guiding member 4.

[0089] The air guiding member 4 has a left air guiding position for guiding air to the left front, a right air guiding position for guiding air to the right front, and a front air guiding position for guiding air to the due front. When the air guiding member 4 is in the right air guiding position, the second side 42 and the fourth side 44 are arranged in sequence in the direction from the air inlet 3321 of the air outlet channel 332 to the air outlet 3322 of the air outlet channel 332. When the air guiding member 4 is in the left air guiding position, the first side 41 and the third side 43 are arranged in sequence in the direction from the air inlet 3321 to the air outlet 3322.

[0090] The outer peripheral contour lines of the air guiding member 4 on the fourth side 44 and the third side 43 are the first contour line. The outer peripheral contour lines of the air guiding member 4 on the second side 42 and the third side 43 are the second contour line. The projected length of the first contour line on the reference plane is D1, and the projected length of the second contour line on the reference plane is D2, where D1≥D2. The reference plane is perpendicular to the first air duct profile 3123.

[0091] The air outlet passage 332 has a second air duct profile 333 disposed opposite to the second volute tongue wall surface 3122. The diameter of the impeller 32 is D. A first reference circle is obtained with the center of the impeller 32 as the center and 1.45D as the diameter. The intersection point of the first reference circle and the first air duct profile 3123 is intersection point A. A perpendicular line g is drawn with intersection point A as the foot of the perpendicular. The intersection point of the perpendicular line g and the second air duct profile 333 is intersection point B. The line segment formed by connecting intersection point A and intersection point B is line segment AB. The length of line segment AB is L1, D1≥0.45*L1, and D2≤0.8*L1.

[0092] The plane where the air flow outlet 3322 is located is the air outlet surface. The width of the air outlet surface in the left - right direction is L2. The distance in the front - back direction between the rotation axis of the air deflector 4 and the air outlet surface is D4, 0.05*L2≤D4≤0.3*L2. In the horizontal direction, the point on the air deflector 4 farthest from the rotation axis of the air deflector 4 is point C. A second reference circle is obtained with the rotation center of the air deflector 4 as the center and passing through point C. The diameter of the second reference circle is D5, 1.1*L1≤D5≤0.95*L2, where L1 is less than L2.

[0093] When the air deflector 4 is in the front air - deflecting position, the maximum distance in the front - back direction between the third side 43 and the air outlet surface is D3, - 0.1*L2≤D3≤0.45*L2; among them, when the third side 43 is located on the front side of the air outlet surface in the front air - deflecting position, the distance in the front - back direction between the third side 43 and the air outlet surface is a positive value, and when the third side 43 is located on the rear side of the air outlet surface, the distance in the front - back direction between the third side 43 and the air outlet surface is a negative value.

[0094] For example, when the air conditioner is operating and the air deflector 4 is in the right air - deflecting position, the impeller 32 drives the air flow to flow into the housing 1 component through the air inlet 12 and flow towards the heat exchanger assembly 2. The air after heat - exchange by the heat exchanger assembly 2 flows towards the air duct 311. The air flow in the air duct 311 can flow into the air outlet passage 332 through the air flow inlet 3321. The air flow in the air outlet passage 332 flows towards the air deflector 4 through the air flow outlet 3322. The air flow flows through the first side 41 and the third side 43 in sequence and flows out towards the air outlet 11 and towards the right front to meet the user's usage requirements. Among them, the shielding area of the second side 42 of the air deflector 4 is small, which can reduce the shielding area of the air flow to reduce the air volume loss, so as to better meet the right air - deflecting effect of the air deflector 4.
