Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning equipment, and in particular, to a wind deflector assembly and an indoor unit having the same. Background Art

[0002] The air supply volume and air supply angle of the indoor unit directly determine the thermal comfort of the indoor unit. As the core component of the indoor unit air supply system, the wind deflector plays a very important role in improving the thermal comfort of the indoor unit.

[0003] In the prior art, due to the movement limitations of the single wind deflector or double wind deflector structure itself, the air supply angle of the indoor unit is limited, resulting in poor cooling and heating comfort of the indoor unit. During the operation of the air conditioner, the cold air or hot air blown out by the indoor unit through the wind deflector directly blows towards the user, reducing the user's comfort. At the same time, the indoor unit cannot quickly increase the temperature in the room during the heating process, reducing the heating efficiency of the air conditioner. In addition, the resistance loss of the air flow in the indoor unit during the diversion process is large in the prior art, resulting in greater power consumption required for the indoor unit to achieve the same cooling or heating effect, increasing the user's usage cost.

[0004] In the prior art (CN111059748A), a wind deflector device for an air conditioner is disclosed. The wind deflector device adopts a push-out type wind deflector, and the wind deflector is provided with wind guiding ribs, so that the wind guiding ribs guide the air flow in the required direction when the air conditioner is in the cooling or heating state, improving the user's comfort. However, such a setting makes the structure of the wind deflector device very complex, and at the same time increases the overall size of the wind deflector device, thereby affecting the overall length of the indoor unit and increasing the overall cost of the indoor unit.

[0005] In the prior art (CN209355454U), a wind deflector assembly and an air conditioner are disclosed. The wind deflector assembly expands the air guiding angle of the wind deflector, so that the air flow blown out through the wind deflector is more evenly distributed in the room, improving the user's comfort. However, the wind deflector adopts a rotation method with a fixed radius, and the movement method is single. At the same time, such a setting limits the movable range of the rotation center of the wind deflector, and the wind deflector cannot move to the most suitable cooling and heating positions.

It should be understood that these embodiments are provided so that the disclosure of the present application is thorough and complete, and the concept of these exemplary embodiments is fully conveyed to those of ordinary skill in the art. In the drawings, for clarity, the thickness of layers and regions may be exaggerated, and the same reference numerals are used to denote the same devices, and thus their description will be omitted.

[0072] Combined with Figures 1 to 17 As shown, according to a specific embodiment of the present application, a wind deflector assembly is provided.

[0073] Specifically, the wind deflector assembly includes a first driving part 10, a first connecting part 20, a second connecting part 30, a wind deflector 40, and a second driving part 50. The first driving part 10 is used to connect to the installation base. The output end of the first driving part 10 is connected to the first end of the first connecting part 20. The first driving part 10 is used to drive the first connecting part 20 to rotate around the first rotation center 110. One end of the second connecting part 30 is connected to the second end of the first connecting part 20. The extension line of the geometric center line in the length direction of the first connecting part 20 and the extension line of the geometric center line in the length direction of the second connecting part 30 are arranged at an angle. The wind deflector 40 is connected to the second end of the second connecting part 30. The wind deflector 40 has a closed position and an open position. The output end of the second driving part 50 is connected to the wind deflector 40. The second driving part 50 is used to drive the wind deflector 40 to rotate around the second rotation center 120 for air guiding operation. Wherein, during the process that the first driving part 10 drives the wind deflector 40 to move from the closed position to the open position, the included angle formed by the extension line of the geometric center line in the length direction of the first connecting part 20 and the extension line of the geometric center line in the length direction of the second connecting part 30 is set to gradually increase.

[0074] Applying the technical solution of the present application, by setting the first driving part 10 to drive the first connecting part 20 to rotate around the first rotation center 110, the air deflector 40 is controlled to move to the open or closed position, and the second driving part 50 drives the air deflector 40 to rotate around the second rotation center 120 to control the change of the air guiding angle of the air deflector 40. During the pushing process of the air deflector 40, the included angle formed by the extension line of the geometric center line in the length direction of the first connecting part 20 and the extension line of the geometric center line in the length direction of the second connecting part 30 gradually increases. The increase of this included angle effectively increases the pushing stroke of the air deflector 40, and the movement track of the air deflector 40 is composed of multiple tracks, making the movement of the air deflector 40 more flexible in a limited space. The structure of the air deflector assembly is simple, which can effectively save the installation space of the air deflector assembly, and then can reduce the dimensions of the indoor unit in the length direction and width direction with this air deflector assembly, so that the indoor unit can achieve miniaturization development and effectively reduce the production cost of the indoor unit. Applying the technical solution of the present application solves the problems of limited stroke of the air deflector 40 and high cost of the indoor unit in the prior art.

[0075] As Figure 11 , Figure 12 and Figure 13 shown, during the process of the first driving part 10 driving the air deflector 40 to move from the closed position to the open position, the distance between the first rotation center 110 and the second rotation center 120 is set to gradually increase. Such a setting increases the pushing stroke of the air deflector 40 and makes the movement of the air deflector 40 more flexible.

[0076] As Figure 3 and Figure 11 shown, the first connecting part 20 includes a first crank 21. The first end of the first crank 21 is connected to the output end of the first driving part 10. The second end of the first crank 21 is connected to the second connecting part 30. The first rotation center 110 is the rotation center of the first crank 21. Such a setting enables the first driving part 10 to drive the first crank 21 to rotate, and further drives the second connecting part 30 to move.

[0077] Specifically, the axis of the output end of the first driving part 10 is set perpendicular to the geometric center line in the length direction of the first crank 21. Such a setting enables the first driving part 10 and the first crank 21 to have good connection stability.

[0078] As Figure 3 and Figure 12As shown, the second connecting member 30 includes a first rocker 31. The first end of the first rocker 31 is rotatably connected to the second end of the first connecting member 20. The second driving portion 50 is connected to the second end of the first rocker 31. The output end of the second driving portion 50 is connected to the air deflector 40. The second rotation center 120 is the rotation center of the output end of the second driving portion 50. Such a setting makes the structure of the second connecting member 30 simple, and at the same time, the second driving portion 50 can control the air guiding angle of the air deflector 40, improving the practicability of the indoor unit.

[0079] As Figure 3 and Figure 4 shown, the first rocker 31 includes a rocker seat 311 and a rocker cover 313. The first end of the rocker seat 311 is rotatably connected to the second end of the first connecting member 20. The second end of the rocker seat 311 has a receiving cavity 312. The second driving portion 50 is disposed in the receiving cavity 312. The rocker cover 313 is connected to the rocker seat 311. A closed space is defined between the rocker cover 313 and the side wall of the receiving cavity 312. Such a setting can hide the second driving portion 50 in the first rocker 31, playing a protective role for the second driving portion 50.

[0080] As Figure 3 and Figure 4 shown, the air deflector assembly further includes a first limiting member 60. The first limiting member 60 is used for connecting to the installation base. The first limiting member 60 is located between the first driving portion 10 and the first rocker 31. A first limiting structure 61 is provided on the surface of the first limiting member 60 facing the first rocker 31. A first limiting protrusion cooperating with the first limiting structure 61 is provided on the surface of the first rocker 31. Such a setting enables the first limiting member 60 to limit the first rocker 31 through the cooperation of the first limiting structure 61 and the first limiting protrusion, strictly restricting the pushing trajectory of the air deflector 40, and improving the practicability and reliability of the indoor unit. Among them, the installation base can be the panel body 100 of the indoor unit. The first limiting member 60 can be integrally formed with the panel body 100, or the first limiting member 60 can be connected to the panel body 100 through a connecting member.

[0081] Further, as Figure 3 and Figure 4As shown, the air deflector assembly further includes a first limiting member 60 and a first slide rail guide rod 200. The first limiting member 60 is used to connect to the installation base. The first limiting member 60 is located between the first driving part 10 and the first rocker 31. A first limiting structure 61 is provided on the surface of the first limiting member 60 facing the first rocker 31. The first slide rail guide rod 200 has a first connecting section 201 and a first guiding section 202. The first connecting section 201 is rotatably connected to the first limiting member 60. The first end of the first guiding section 202 is connected to the first rocker 31, and the second end of the first guiding section 202 extends into the first limiting structure 61. With such a setting, by connecting the first slide rail guide rod 200 to the first limiting member 60 and the first rocker 31 at the same time, the limiting effect formed by the first limiting member 60 and the first slide rail guide rod 200 on the first rocker 31 is more accurate and reliable.

[0082] As Figure 4 shown, the first limiting member 60 is provided with a second limiting protrusion 62. The first connecting section 201 is rotatably sleeved on the second limiting protrusion 62. The axis of the length direction of the first guiding section 202 is located on one side of the axis of the first connecting section 201. With such a setting, the connection between the first limiting member 60 and the first slide rail guide rod 200 is firm and reliable, and the movement of the first guiding section 202 is more accurate.

[0083] As Figure 10 shown, the first limiting structure 61 is an arc-shaped groove. With such a setting, the movement of the first rocker 31 is more stable and reliable during the movement, and at the same time, the stroke of the air deflector 40 is increased.

[0084] Specifically, the air deflector assembly includes a third driving part 140, a third connecting member 70, and a fourth connecting member 80. The third driving part 140 is connected to the installation base. The output end of the third driving part 140 is connected to the first end of the third connecting member 70. The third driving part 140 can drive the third connecting member 70 to rotate. The rotation center of the third connecting member 70 is the rotation center of the output end of the third driving part 140. The first end of the fourth connecting member 80 is connected to the second end of the third connecting member 70, and the second end of the fourth connecting member 80 is connected to the air deflector 40. The fourth connecting member 80 is disposed opposite to the second connecting member 30. The second driving part 50 drives the air deflector 40 to rotate relative to the fourth connecting member 80 for air guiding operation. The rotation center of the fourth connecting member 80 is coaxially arranged with the second rotation center 120. The third driving part 140 and the first driving part 10 drive the air deflector 40 to be in the open position and the closed position. With such a setting, the third driving part 140 can drive the third connecting member 70 to cooperate with the fourth connecting member 80 to move, thereby driving the air deflector 40 to move along a preset trajectory, and at the same time ensuring that the fourth connecting member 80 and the second connecting member 30 move synchronously, making the air deflector 40 move more smoothly during the movement.

[0085] As Figure 5As shown, the air deflector assembly further includes a second limiting member 90. The second limiting member 90 is connected to the installation base. The second limiting member 90 is located outside the fourth connecting member 80. A second limiting structure 91 is provided on one side of the second limiting member 90 facing the fourth connecting member 80. The fourth connecting member 80 is provided with a third limiting protrusion that cooperates with the second limiting structure 91. This setting enables the second limiting member 90 to limit the fourth connecting member 80 through the cooperation of the second limiting structure 91 and the third limiting protrusion, strictly restricting the movement trajectory of the air deflector 40 and improving the practicability and reliability of the indoor unit. Among them, the installation base can be the panel body 100 of the indoor unit. The second limiting member 90 can be integrally formed with the panel body 100, or the second limiting member 90 can also be connected to the panel body 100 through a connecting member.

[0086] As Figure 5 and Figure 6 shown, the air deflector assembly further includes a second limiting member 90 and a second slide rail guide rod 300. The second limiting member 90 is connected to the installation base. The second limiting member 90 is located between the third driving part 140 and the third connecting member 70. A second limiting structure 91 is provided on the surface of the second limiting member 90 facing the third connecting member 70. The second slide rail guide rod 300 has a second connecting section 301 and a second guiding section 302. The second connecting section 301 is rotatably connected to the second limiting member 90. The first end of the second guiding section 302 is connected to the fourth connecting member 80, and the second end of the second guiding section 302 extends into the second limiting structure 91. This setting enables the second limiting member 90 and the second limiting member 90 to form a more accurate and reliable limit on the fourth connecting member 80 by connecting the second slide rail guide rod 300 to the second limiting member 90 and the fourth connecting member 80 at the same time.

[0087] Furthermore, the second limiting member 90 is provided with a fourth limiting protrusion. The second connecting section 301 is rotatably sleeved on the fourth limiting protrusion. The axis of the length direction of the second guiding section 302 is located on one side of the axis of the second connecting section 301. This setting enables the connection between the second limiting member 90 and the second slide rail guide rod 300 to be firm and reliable, and the movement of the second guiding section 302 to be more accurate.

[0088] As Figure 5 and Figure 6 shown, the third connecting member 70 includes a second crank 71. The first end of the second crank 71 is connected to the output end of the third driving part 140. The second end of the second crank 71 is connected to the fourth connecting member 80. This setting makes the structure of the third connecting member 70 simple, and at the same time, the third driving part 140 can drive the second crank 71 to rotate and then drive the fourth connecting member 80 to move.

[0089] The fourth connecting member 80 includes a second rocker 81. The first end of the second rocker 81 is rotatably connected to the second end of the second crank 71. The second end of the second rocker 81 is connected to the air deflector 40. Such a setting makes the structure of the fourth connecting member 80 simple. At the same time, the fourth connecting member 80 can move in cooperation with the second crank 71 to drive the air deflector 40 to move to the closed position and the open position.

[0090] Furthermore, the second limiting structure 91 is an arc-shaped limiting groove. Such a setting makes the movement of the fourth connecting member 80 more stable and reliable. At the same time, the stroke of the air deflector 40 is increased.

[0091] As Figure 6 shown, the third driving part 140 includes a third motor 141 and a second bushing 142. The driving end of the third motor 141 is connected to the first end of the second bushing 142. The second end of the second bushing 142 is connected to the second crank 71. Such a setting enables the third motor 141 to drive the second crank 71 to rotate. At the same time, the setting of the second bushing 142 makes the output shaft of the third motor 141 not exposed outside, avoiding accidents caused by accidental contact of personnel with the motor output shaft. It can also make the movement of the second crank 71 more stable.

[0092] The air deflector assembly in the above embodiment can also be used in the technical field of air conditioning equipment. That is, according to another aspect of the present application, an indoor unit is provided, including an air deflector assembly, and the air deflector assembly is the air deflector assembly in the above embodiment.

[0093] As Figure 1 shown, the indoor unit includes a panel body 100, and the first driving part 10 of the air deflector assembly is connected to the panel body 100. The indoor unit has a cooling mode and a heating mode. When the indoor unit is in the heating mode, the extension line of the geometric center line in the length direction of the first connecting member 20 and the extension line of the geometric center line in the length direction of the second connecting member 30 form an angle greater than the angle formed by the extension line of the geometric center line in the length direction of the first connecting member 20 and the extension line of the geometric center line in the length direction of the second connecting member 30 when the indoor unit is in the cooling mode. Such a setting enables the air deflector assembly to be reliably fixed on the panel body 100. At the same time, compared with the movement of the air deflector 40 in the cooling mode of the indoor unit, the stroke of the air deflector 40 pushed out in the heating mode is farther.

[0094] Furthermore, when the indoor unit is in the cooling mode, the air flow at the air outlet of the indoor unit is blown out horizontally after being guided by the air deflector 40. When the indoor unit is in the heating mode, the air flow at the air outlet of the indoor unit is blown out vertically after being guided by the air deflector 40. Such a setting enables the indoor unit to control the air guiding angle of the air deflector 40 according to different operating modes, improving the practicability of the indoor unit. Among them, the F1 direction is the horizontal direction, and the F2 direction is the vertical direction.

[0095] Specifically, when the air deflector 40 is in the closed position, the distance between the first rotation center 110 and the second rotation center 120 is Y0. When the indoor unit is in the cooling mode, the distance between the first rotation center 110 and the second rotation center 120 is Y1. When the indoor unit is in the heating mode, the distance between the first rotation center 110 and the second rotation center 120 is Y2. Among them, Y0 < Y1 < Y2. Such a setting enables the indoor unit to quickly achieve cooling and heating within a limited time, and when the indoor unit is in the heating mode, the hot air is blown out along the vertical direction, and when the indoor unit is in the cooling mode, the cold air is blown out along the horizontal direction.

[0096] When the air deflector 40 is in the closed position, the angle between the geometric center line in the length direction of the first connecting member 20 and the geometric center line in the length direction of the first rocker 31 is α0. When the indoor unit is in the cooling mode, the angle between the geometric center line in the length direction of the first connecting member 20 and the geometric center line in the length direction of the first rocker 31 is α1. When the indoor unit is in the heating mode, the angle between the geometric center line in the length direction of the first connecting member 20 and the geometric center line in the length direction of the first rocker 31 is α2. Among them, α0 < α1 < α2. Such a setting enables the indoor unit to control the change of α according to different operating modes, improving the heat exchange efficiency of the indoor unit.

[0097] The distance between the first rotation center 110 and the second rotation center 120 can be obtained by the following formula:

[0098]

[0099] Among them, Y is the distance between the first rotation center 110 and the second rotation center 120. L 1 is the length of the first crank 21; L 2 is the length of the first rocker 31. α is the angle between the geometric center line in the length direction of the first crank 21 and the geometric center line in the length direction of the first rocker 31. Such a setting enables the distance between the first rotation center 110 and the second rotation center 120 to be calculated and selected according to the actual situation, making the air deflector assembly applicable to indoor units of different models and improving the practicability of the air deflector assembly.

[0100] In this application, the first driving part 10 includes a first motor 11 and a first shaft sleeve 12. The driving end of the first motor 11 is connected to the first end of the first shaft sleeve 12, and the second end of the first shaft sleeve 12 is connected to the first connecting part 20. The second driving part 50 includes a second motor 51. The driving end of the second motor 51 is connected to a speed reducer, and the output end of the speed reducer is connected to the air deflector 40. Such an arrangement enables the second driving part 50 to output appropriate speed and torque to drive multiple transmission components, and at the same time plays a role in fixing the entire air deflector assembly, improving the practicability and reliability of the air deflector assembly.

[0101] Specifically, L 1 It can also be the length of the second crank 71. L 2 It can also be the length of the fourth connecting part 80. α can also be the included angle between the geometric center line in the length direction of the second crank 71 and the geometric center line in the length direction of the fourth connecting part 80.

[0102] In the technical solution of this application, the air deflector 40 is fully pushed out by the first driving part 10 and the third driving part 140, and the second driving part 50 drives the air deflector 40 to rotate, realizing the effect that cold air is blown out horizontally and hot air is blown out vertically, effectively improving the user experience. At the same time, such an arrangement also increases the movement stroke of the air deflector 40. This arrangement solves the problem that the cold air directly blows towards the user due to the structural limitation of the air deflector 40 itself in the existing indoor unit. The air deflector assembly in this application has a simple structure, can meet the movement requirements of the air deflector 40 in different indoor units with different appearance sizes under different operating modes, and can also design the operating path of the air deflector 40 according to the actual situation of the indoor unit working.

[0103] In this application, the indoor unit has a housing with an air outlet. The air deflector assembly opens and closes the air outlet under the combined drive of the first driving part 10 and the third driving part 140, and the second driving part 50 drives the air deflector 40 to rotate. At the same time, the air deflector 40 has multiple open positions and multiple closed positions, and the air deflector angle of the air deflector 40 can be adjusted by the second driving part 50 when the air deflector 40 is located at any open position or closed position.

[0104] Furthermore, the axis in the length direction of the first guiding section 202 is parallel to the axis of the first connecting section 201. The axis in the length direction of the second guiding section 302 is parallel to the axis of the second connecting section 301.

[0105] Further, the first end of the first guiding section 202 is connected to the first rocker 31, and the first end of the second guiding section 302 is connected to the fourth connecting member 80. The first rocker 31 is rotatably connected to the first crank 21. A first convex post can be provided on the first rocker 31, and a first through hole can be provided at one end of the first crank 21. The first convex post is inserted into the first through hole of the first crank 21, so that the first rocker 31 can rotate around the first through hole. The first crank 21 is further provided with a second through hole at the other end, and the first crank 21 can be connected to the output end of the first driving part 10 through the second through hole.

[0106] Both ends of the second crank 71 are provided with a third through hole and a fourth through hole. The second crank 71 is connected to the output end of the third driving part 140 through the fourth through hole thereon. The second rocker 81 is provided with a second convex post, and the second convex post is inserted into the third through hole of the second crank 71, so that the second rocker 81 can rotate around the third through hole.

[0107] The air deflector 40 is provided with a first mounting hole and a second mounting hole. The output shaft of the second driving part 50 is inserted into the first mounting hole, so that one side of the air deflector 40 is mounted on the first rocker 31. Similarly, one end of the second rocker 81 is inserted into the second mounting hole, so that the other side of the air deflector 40 is mounted on the second rocker 81.

[0108] The first guiding section 202 is installed at the first limiting structure 61 and can slide along the first limiting structure 61. Similarly, the second guiding section 302 is installed at the second limiting structure 91 and can slide along the second limiting structure 91. The first limiting member 60 and the second limiting member 90 are installed in parallel, so that the trajectories of the first limiting structure 61 and the second limiting structure 91 coincide along the rotation axis direction.

[0109] Further, the first crank 21 and the second crank 71 are arranged oppositely and move synchronously, that is, the first crank 21 and the second crank 71 always remain parallel when the air deflector assembly is running.

[0110] As Figure 13 shown, in another embodiment of the present application, when the air deflector assembly is in the initial state, that is, when the indoor machine is closed, the air deflector 40 covers the air outlet, so that the air outlet is closed. The first rocker 31 is further provided with a third convex post, and the second rocker 81 is further provided with a fourth convex post. When the air deflector assembly is in the initial state, the third convex post and the fourth convex post are respectively located at the starting points of the guide rail structures of the first limiting member 60 and the second limiting member 90. At this time, the distance between the first rotation center 110 and the second rotation center 120 is Y0, and the included angles between the first crank 21 and the first rocker 31 and between the second crank 71 and the second rocker 81 are both α0.

[0111] By applying the technical solution of the present application, the air supply angle of the indoor unit is effectively increased, solving the problem of the uncomfortable experience brought to users by the direct blowing of cold air caused by the structural limitation of the air deflector 40 in the existing indoor unit. Driving components, cranks, connecting rods and slide rail components are arranged on both the left and right sides of the air deflector 40 of the indoor unit, and the corresponding components have the same structure or are mirror structures, making the pushing out of the air deflector more stable. For example, when the first motor 11 rotates, it drives the first crank 21 to push the first rocker 31 to rotate. At the same time, the first guiding section 202 slides along the first limiting structure 61. Driven by these two motions, the first rocker 31 completes the pushing out action of the air deflector 40.

[0112] In another embodiment of the present application, when the indoor unit is started, the first driving part 10 and the third driving part 140 are started simultaneously. The first driving part 10 drives the first crank 21 to move, and the first crank 21 drives the first rocker 31 to move along the first limiting structure 61. On the other side, the third driving part 140 drives the second crank 71 to move, and the second crank 71 drives the second rocker 81 to move along the second limiting structure 91. Under the combined drive of the first motor 11 and the third motor 141, the first rockers 31 and the second rockers 81 on both sides complete the pushing out action simultaneously. During the pushing out process of the air deflector 40, the included angle between the geometric center line in the length direction of the first crank 21 and the geometric center line in the length direction of the first rocker 31 will change with the change of the pushing out distance. Due to the change of the included angle, the distance Y between the first rotation center 110 and the second rotation center 120 also changes accordingly. Y is the rotation radius of the air deflector 40, that is, during the pushing out process of the air deflector 40, the rotation radius gradually increases, making the pushing out stroke of the air deflector 40 larger.

[0113] Further, in this embodiment, the air deflector 40 of the indoor unit is pushed out to a position far from the air outlet by the first driving part 10 and the third driving part 140 together, and the rotation of the air deflector 40 in the cooling mode and the heating mode is respectively realized. By adopting the technical solution of the present application, the structure of the air guiding assembly is simple and compact, which can meet indoor units with different appearance sizes, and realizes the technical effect that cold air is blown out horizontally and hot air is blown out vertically, effectively improving the user experience.

[0114] As Figure 11 shown, when the indoor unit is in the cooling mode, first, the air deflector 40 is pushed out to the open position by the first driving part 10 and the third driving part 140, and then the second driving part 50 drives the air deflector 40 to rotate to the horizontal position to guide the air flow to be blown out horizontally.

[0115] As Figure 12As shown, when the indoor unit is in the heating mode, the air deflector 40 is first pushed out to the open position by the first driving part 10 and the third driving part 140, and then the second driving part 50 drives the air deflector 40 to rotate to the vertical position to guide the air flow to blow vertically.

[0116] Both the first driving part 10 and the third driving part 140 are provided with stepping motors, and the two stepping motors are connected through corresponding bushings and transmit torque to the corresponding cranks.
