Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning equipment, and in particular to an air guide plate 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 air guide plate 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 air guide plate or double air guide plate 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 of the indoor unit through the air guide plate is directly blown to the user, which reduces the user's comfort. At the same time, the indoor unit cannot quickly increase the temperature in the room during the heating process, which reduces the heating efficiency of the air conditioner. In addition, in the prior art, the resistance loss of the air flow in the indoor unit during the flow diversion process is large, resulting in greater power consumption required for the indoor unit to achieve the same cooling or heating effect, increasing the user's cost of use.

[0004] The prior art (CN111059748A) discloses an air guide device for an air conditioner. The air guide device adopts a push-out air guide plate, which is provided with air guide ribs, so that the air guide ribs guide the airflow in the required direction when the air conditioner is in cooling or heating state, thereby improving the user's comfort. However, such a setting makes the structure of the air guide device very complicated, and at the same time increases the overall size of the air guide device, thereby affecting the overall length of the indoor unit, resulting in an increase in the overall cost of the indoor unit.

[0005] The prior art (CN209355454U) discloses an air guide assembly and an air conditioner, which expands the air guide angle of the air guide plate, so that the airflow blown out by the air guide plate is more evenly distributed in the room, improving the user's comfort. However, the air guide plate adopts a fixed radius rotation mode, and the movement mode is single. At the same time, such a setting limits the movable range of the rotation center of the air guide plate, and the air guide plate cannot move to the most suitable cooling and heating position.

[0063] Combination Figures 1 to 13 As shown, according to a specific embodiment of the present application, a wind deflector assembly is provided.

[0064] Specifically, the air deflector assembly includes a first driving unit 10, a first connecting assembly 20, a second connecting assembly 30, an air deflector 40, and a second driving unit 50. The output end of the first driving unit 10 is connected to a part of the first connecting assembly 20. The first driving unit 10 is used to drive the first connecting assembly 20 to rotate around the first rotation center 110. A part of the second connecting assembly 30 is connected to another part of the first connecting assembly 20. The air deflector 40 is connected to another part of the second connecting assembly 30. The air deflector 40 has a closed position and an open position. The output end of the second driving unit 50 is connected to the air deflector 40. The second driving unit 50 is used to drive the air deflector 40 to rotate around the second rotation center 120 to perform a wind deflecting operation. In the process of the first driving unit 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 gradually increased, and in the process of the first driving unit 10 driving the air deflector 40 to move from the open position to the closed position, the distance between the first rotation center 110 and the second rotation center 120 is gradually reduced.

[0065] By applying the technical solution of the present application, the first driving unit 10 is set to drive the first connecting assembly 20 to rotate around the first rotation center 110, and the air guide plate 40 is controlled to move to the open or closed position. The second driving unit 50 drives the air guide plate 40 to rotate around the second rotation center 120, and the air guide angle of the air guide plate 40 is controlled. During the pushing process of the air guide plate 40, the distance between the first rotation center 110 and the second rotation center 120 gradually increases, so that the pushing stroke of the air guide plate 40 is effectively increased, and the movement trajectory of the air guide plate 40 is composed of multiple sections of trajectories, so that the air guide plate 40 can move more flexibly in a limited space. The structure of the air guide plate assembly is simple, which can effectively save the installation space of the air guide plate assembly, and then can reduce the length and width dimensions of the indoor unit with the air guide plate assembly, so that the indoor unit can achieve miniaturization and effectively reduce the production cost of the indoor unit. By applying the technical solution of the present application, the problem of limited stroke of the air guide plate 40 and high cost of the indoor unit in the prior art is solved.

[0066] like Figure 3 and Fig.11As shown, the first connecting component 20 includes a first connecting member 21 and a second connecting member 22. One end of the first connecting member 21 is connected to the output end of the first driving unit 10. The first end of the second connecting member 22 is connected to the first connecting member 21 and is arranged at an angle. The second end of the second connecting member 22 is connected to the second connecting component 30, and the first rotation center 110 is the rotation center of the first connecting member 21. This arrangement makes the first connecting component 20 simple and reliable in structure, and at the same time makes the first connecting member 21 and the second connecting member 22 have good connection stability. Among them, the connection position between the first end of the second connecting member 22 and the first connecting member 21 can be changed according to actual needs, for example, the connection position between the first end of the second connecting member 22 and the first connecting member 21 can be arranged close to one side of the first driving unit 10.

[0067] In order to make the connection between the first connecting member 21 and the second connecting member 22 more firmly, the first connecting member 21 and the second connecting member 22 are integrally provided.

[0068] Specifically, Figure 4 As shown, the first connecting member 21 includes a first connecting rod. One end of the first connecting rod is connected to the output end of the first driving unit 10. The second connecting member 22 includes a first crank. The first end of the first crank is connected to the first connecting rod. The second end of the first crank is connected to the second connecting assembly 30. The axis of the first connecting rod is arranged perpendicular to the geometric center line of the length direction of the first crank, and the connection between the first end of the first crank and the first connecting rod is arranged near the side where the output end of the first driving unit 10 is located. This arrangement allows the first driving unit 10 to drive the first connecting member 21 and the second connecting member 22 to move in coordination, thereby driving the second connecting assembly 30 to move.

[0069] Further, the second connecting assembly 30 includes a first rocking arm 31. The first end of the first rocking arm 31 is rotatably connected to the second end of the second connecting member 22. The second driving unit 50 is connected to the second end of the first rocking arm 31. The output end of the second driving unit 50 is connected to the air guide plate 40. The second rotation center 120 is the rotation center of the output end of the second driving unit 50. This arrangement makes the second connecting assembly 30 simple in structure, and the second driving unit 50 can control the air guide angle of the air guide plate 40, thereby improving the practicality of the indoor unit.

[0070] like Figure 4As 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 second connecting member 22. The second end of the rocker seat 311 has a receiving cavity 312, and the second driving part 50 is arranged in the receiving cavity 312. The rocker cover 313 is connected to the rocker seat 311. A closed space is formed between the rocker cover 313 and the side wall of the receiving cavity 312. In this way, the second driving part 50 can be hidden in the first rocker 31, which plays a protective role for the second driving part 50.

[0071] Specifically, the air guide plate assembly also includes a first limiter 60. The first limiter 60 is connected to the installation base. The first limiter 60 is located between the first driving part 10 and the first rocker 31, and the surface of the first limiter 60 facing the first rocker 31 is provided with a first limiter structure 61. The surface of the first rocker 31 is provided with a first limiter protrusion 314 that cooperates with the first limiter structure 61. This arrangement enables the first limiter 60 to limit the first rocker 31 through the cooperation of the first limiter structure 61 and the first limiter protrusion 314, strictly limits the push-out trajectory of the air guide plate 40, and improves the practicality and reliability of the indoor unit. Among them, the installation base can be the panel body 100 of the indoor unit, the first limiter 60 can be integrally formed with the panel body 100, and the first limiter 60 can also be connected to the panel body 100 through a connecting member.

[0072] Furthermore, if Fig.10 As shown, the first limiting structure 61 is an arc groove. This arrangement makes the first rocker 31 more stable and reliable during movement, while increasing the travel of the air guide plate 40.

[0073] Specifically, the first stopper 60 is provided with a first through hole for the output end of the first driving unit 10 to pass through. This arrangement enables the first stopper 60 to play an auxiliary supporting role for the entire air guide plate assembly, thereby improving the reliability of the indoor unit.

[0074] like Figure 5 , Figure 6 and Fig.11As shown, the air deflector assembly includes a third connecting assembly 70 and a fourth connecting assembly 80. The first connecting member 21 is connected to the third connecting assembly 70. The first connecting member 21 can drive the third connecting assembly 70 to rotate. The rotation center of the third connecting assembly 70 is the rotation center of the first connecting member 21. A part of the fourth connecting assembly 80 is connected to the third connecting assembly 70. Another part of the fourth connecting assembly 80 is connected to the air deflector 40. The third connecting assembly 70 is arranged opposite to the second connecting assembly 30. The second driving part 50 drives the air deflector 40 to rotate relative to the fourth connecting assembly 80. The rotation center of the fourth connecting assembly 80 is arranged coaxially with the second rotation center 120. This arrangement enables the first connecting member 21 to drive the third connecting assembly 70 to rotate, and then drives the fourth connecting assembly 80 to move according to a preset trajectory, ensuring that the third connecting assembly 70 moves synchronously with the second connecting assembly 30, so that the air deflector 40 is more stable during the movement process.

[0075] Furthermore, if Figure 6 As shown, the air guide plate assembly also includes a second limit member 90. The second limit member 90 is connected to the installation base. The second limit member 90 is located on the outside of the fourth connection assembly 80. The second limit member 90 is provided with a second limit structure 91 on the side facing the fourth connection assembly 80. The fourth connection assembly 80 is provided with a second limit protrusion 81 that cooperates with the second limit structure 91. This arrangement enables the second limit member 90 to form a limit on the fourth connection assembly 80 through the cooperation between the second limit structure 91 and the second limit protrusion 81, strictly limits the movement trajectory of the air guide plate 40, and improves the practicality and reliability of the indoor unit. Among them, the installation base can be the panel body 100 of the indoor unit, the second limit member 90 can be integrally formed with the panel body 100, and the second limit member 90 can also be connected to the panel body 100 through a connector.

[0076] Specifically, Figure 5 and Figure 6 As shown, the third connecting assembly 70 includes a second crank 71. The first end of the second crank 71 is connected to the first connecting member 21, and the second end of the second crank 71 is connected to the fourth connecting assembly 80. This arrangement makes the third connecting assembly 70 simple in structure, and the first connecting member 21 can drive the fourth connecting assembly 80 to move through the second crank 71.

[0077] Further, the fourth connecting assembly 80 includes a second rocker 82. The first end of the second rocker 82 is rotatably connected to the second end of the second crank 71. The second end of the second rocker 82 is connected to the air deflector 40. The second rocker 82 is provided with a second limiting protrusion 81. This arrangement makes the fourth connecting assembly 80 simple in structure, and the fourth connecting assembly 80 can move in coordination with the second crank 71 to drive the air deflector 40 to move to the closed position and the open position.

[0078] Furthermore, the second limiting structure 91 is an arc-shaped limiting groove, which makes the second rocker 82 more stable and reliable during movement, and increases the travel of the air guide plate 40.

[0079] Specifically, Figure 6 As shown, a second through hole is provided on the second stopper 90. A rotatable shaft sleeve 92 is provided in the second through hole. The first connecting member 21 is connected to the shaft sleeve 92. This arrangement enables the shaft sleeve 92 to rotate with the first connecting member 21, and at the same time plays a role in supporting the first connecting member 21, thereby avoiding indoor unit failure caused by insufficient rigidity of the first connecting member 21. This arrangement can also prevent the first connecting member 21 from generating a huge radial runout, effectively ensuring the motion accuracy of the first connecting member 21.

[0080] like Figure 4 As shown, the first driving unit 10 includes a first motor 11 and a first reducer 12. The first reducer 12 is connected to the mounting base. The driving end of the first motor 11 is connected to the first reducer 12. The output end of the first reducer 12 is connected to the first connecting member 21. This arrangement enables the first driving unit 10 to output a suitable speed and torque to drive multiple transmission components, and also plays a role in fixing the entire air deflector assembly, thereby improving the practicality and reliability of the air deflector assembly.

[0081] The second driving unit 50 includes a second motor 51 and a second reducer 52. The driving end of the second motor 51 is connected to the second reducer 52. The output end of the second reducer 52 is connected to the air guide plate 40. This arrangement enables the second driving unit 50 to output a suitable rotation speed and torque to drive the air guide plate 40 to rotate to a desired air guide angle, thereby ensuring the accuracy and reliability of the movement of the air guide plate 40.

[0082] The air guide plate 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 guide plate assembly, and the air guide plate assembly is the air guide plate assembly in the above embodiment.

[0083] like Figure 1 , Figure 2 , Fig.11 and Fig.12As shown in the figure, the indoor unit includes a panel body 100. 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 cooling mode, the air flow at the air outlet of the indoor unit is guided by the air deflector 40 and blown out along the F1 direction. When the indoor unit is in the heating mode, the air flow at the air outlet of the indoor unit is guided by the air deflector 40 and blown out along the F2 direction. 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 heat exchange efficiency of the indoor unit. Among them, the F1 direction is the horizontal direction, and the F2 direction is the vertical direction.

[0084] Further, 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, where 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.

[0085] Further, when the air deflector 40 is in the closed position, the included angle between the geometric center line in the length direction of the second connecting member 22 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 included angle between the geometric center line in the length direction of the second connecting member 22 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 included angle between the geometric center line in the length direction of the second connecting member 22 and the geometric center line in the length direction of the first rocker 31 is α2. Among them, α0 < α1 < α2. Among them, if the first rocker 31 is a rocker with an irregular shape, the geometric center line in the length direction of the first rocker 31 is the geometric center line in the length direction of the end close to the first connecting member 21. 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.

[0086] The distance between the first rotation center 110 and the second rotation center 120 can be obtained by the following formula:

[0087]

[0088] 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 second connecting member 22. L 2is the length of the first rocker 31. α is the angle between the geometric center line of the length direction of the second connecting member 22 and the geometric center line of the length direction of the first rocker 31. This arrangement allows the distance between the first rotation center 110 and the second rotation center 120 to be calculated and selected according to actual conditions, so that the air guide plate assembly is applicable to indoor units of different models, thereby improving the practicality of the air guide plate assembly.

[0089] In the technical solution of the present application, the first driving unit 10 drives the air deflector 40 to be fully pushed out, and the second driving unit 50 drives the air deflector 40 to rotate, which effectively improves the user experience. At the same time, such a setting also increases the movement stroke of the air deflector 40. Such a setting solves the problem of the existing indoor unit where cold air is directly blown to the user due to the structural limitation of the air deflector 40 itself. The air deflector assembly in the present application has a simple structure and can meet the movement requirements of the air deflector 40 of indoor units of different appearance sizes in different operating modes. The running path of the air deflector 40 can also be designed according to the actual working conditions of the indoor unit.

[0090] In the present application, the indoor unit has a shell, and the shell has an air outlet. The air guide plate assembly realizes the opening and closing of the air outlet under the joint drive of the first driving unit 10 and the second driving unit 50. When the indoor unit is in the cooling mode, the air guide plate 40 is first pushed to the open position by the first driving unit 10, and then the second driving unit 50 drives the air guide plate 40 to rotate to a horizontal position to guide the airflow to blow out horizontally. When the indoor unit is in the heating mode, the air guide plate 40 is first pushed to the open position by the first driving unit 10, and then the second driving unit 50 drives the air guide plate 40 to rotate to a vertical position to guide the airflow to blow out vertically.

[0091] Specifically, L 1 It can also be the length of the second crank 71. 2 Alternatively, it may be the length of the fourth connecting assembly 80. Alternatively, α may be the angle between the geometric center line of the second crank 71 in the longitudinal direction and the geometric center line of the fourth connecting assembly 80 in the longitudinal direction.

[0092] In the present application, the indoor unit has a shell, and the shell has an air outlet. The air guide plate assembly is driven by the first driving unit 10 to open and close the air outlet, and the second driving unit 50 drives the air guide plate 40 to rotate. At the same time, the air guide plate 40 has multiple open positions and multiple closed positions. The air guide angle of the air guide plate 40 can be adjusted by the second driving unit 50 when the air guide plate 40 is in any open position or closed position.

[0093] Furthermore, the second connecting member 22 and the second crank 71 are arranged relative to each other and move synchronously, that is, when the air guide plate assembly is in operation, the second connecting member 22 and the second crank 71 are always kept parallel.

[0094] In another embodiment of the present application, the first driving part 10, the second connecting member 22, the first rocker 31 and the first stopper 60 are arranged on the left side of the air deflector 40. The second crank 71, the second rocker 82 and the second stopper 90 are arranged on the right side of the air deflector 40. The first driving part 10 of the air deflector 40 is connected to and transmits the torque provided by the first motor 11 to the transmission component on the right side of the air deflector 40 through the first connecting member 21. The first connecting member 21 makes the second connecting member 22 rotate synchronously with the second crank 71.

[0095] The air guide plate 40 is provided with a first mounting hole and a second mounting hole, and the output shaft of the second driving unit 50 is inserted into the first mounting hole, so that one side of the air guide plate 40 is mounted on the first rocker 31. Similarly, one end of the second rocker 82 is inserted into the second mounting hole, so that the other side of the air guide plate 40 is mounted on the second rocker 82.

[0096] In another embodiment of the present application, when the indoor unit is started, the first driving part 10 drives the second connecting member 22 to move, and the second connecting member 22 drives the first rocker 31 to move along the first limiting structure 61. On the other side, the first connecting member 21 drives the second crank 71 to move, and the second crank 71 drives the second rocker 82 to move along the second limiting structure 91. Driven by the first motor 11, the first rocker 31 and the second rocker 82 on the left and right sides simultaneously complete the pushing action. During the pushing process of the air guide plate 40, the angle between the geometric center line of the length direction of the second connecting member 22 and the geometric center line of the length direction of the first rocker 31 will change with the change of the pushing distance. Due to the change in the 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 guide plate 40, that is, during the pushing process of the air guide plate 40, the rotation radius gradually increases, so that the pushing stroke of the air guide plate 40 is larger.

[0097] Furthermore, in this embodiment, the air guide plate 40 of the indoor unit is pushed to a position away from the air outlet by the first driving unit 10, and the air guide plate 40 is rotated in the cooling mode and the heating mode respectively. With the technical solution of the present application, the structure of the air guide assembly is simple and compact, and the technical effect of blowing out cold air in the horizontal direction and hot air in the vertical direction is achieved.

[0098] like Fig.11 As shown, when the indoor unit is in cooling mode, the air guide plate 40 is first pushed to the open position by the first driving unit 10, and then the second driving unit 50 drives the air guide plate 40 to rotate to a horizontal position to guide the airflow to blow out horizontally.

[0099] like Fig.12 As shown, when the indoor unit is in the heating mode, the air guide plate 40 is first pushed to the open position by the first driving unit 10, and then the second driving unit 50 drives the air guide plate 40 to rotate to the vertical position to guide the airflow to blow out vertically.

[0100] The first driving unit 10 includes a first motor 11 and a first reducer 12. After the first motor 11 is turned on, the output shaft of the first reducer 12 will output torque, and the output shaft of the first reducer 12 is fixedly assembled with the first connecting member 21. The second connecting member 22 is provided with a first through hole and a second through hole at both ends, and the second connecting member 22 is installed on the first connecting member 21 through the first through hole thereon. The second motor 51 is installed in the accommodating cavity 312 of the first rocker 31, and the torque is output through the output shaft of the second motor 51. The first rocker 31 is provided with a first boss inserted in the second through hole of the second connecting member 22, so that the first rocker 31 can rotate around the second through hole.

[0101] Further, the right side of the air guide plate is provided with a second crank 71, a second rocker 82, a second stopper 90, and a shaft sleeve 92. The second crank 71 is provided with a third through hole and a fourth through hole at both ends, and the second crank 71 is installed on the first connecting member 21 through the third through hole thereon. The second rocker 82 is provided with a second boss inserted in the fourth through hole of the second crank 71, so that the second rocker 82 can rotate around the fourth through hole.

[0102] The first limiting protrusion 314 is installed at the first limiting structure 61 and can slide along the first limiting structure 61. Similarly, the second limiting protrusion 81 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 first limiting structure 61 and the second limiting structure 91 overlap along the rotation axis direction.

[0103] like Fig.13 As shown, in another embodiment of the present application, when the air deflector assembly is in the initial state, that is, when the indoor unit is closed, the air deflector 40 covers the air outlet to close the air outlet. When the air deflector assembly is in the initial state, the first limiting protrusion 314 and the second limiting protrusion 81 are respectively located at the starting point of the guide rail structure 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 angle between the second connecting member 22 and the first rocker 31 and the angle between the second crank 71 and the second rocker 82 are both α0.
