[0044] Air conditioners use air guides to direct the airflow from the air outlet. The air outlet is also equipped with a grille to straighten the airflow. Existing systems typically only have a single air guide plate, which can only swing along the air outlet. This results in a single airflow pattern and is unable to effectively straighten the airflow under different operating conditions. It can even obstruct airflow from certain angles, affecting the air volume and temperature control performance of the air conditioner.

[0045] To this end, the present application proposes an air-conditioning indoor unit, which aims to solve the above-mentioned problems and has a larger air outlet range and better air supply comfort, and can meet the usage requirements of different working conditions.

[0046] In one embodiment of the present application, as shown in Figures 1 to 6, the air-conditioning indoor unit 100 includes a shell 110 and an air guide assembly 130. An air duct 120 is formed in the shell 110, and the air duct 120 has an air outlet 124. The air guide assembly 130 is arranged at the air outlet 124 and includes a first air guide plate 140 and a second air guide plate 150. The first air guide plate 140 and the second air guide plate 150 can be rotated to close the air outlet 124 or change the opening of the air outlet 124.

[0047] 1 to 10 , the housing 110 includes a chassis 111 and a face frame 112. The chassis 111 and the face frame 112 cooperate to form an air duct 120. The air duct 120 has an air outlet 124. Hot air or cold air blown out of the air conditioner indoor unit 100 can be blown into the room through the air outlet 124. An air guide assembly 130 is provided at the air outlet 124. The first and second air guide plates 140 and 150 can be rotated to close the air outlet 124 or change the opening of the air outlet 124, thereby guiding the airflow blown out from the air outlet 124. The arrangement of the first and second air guide plates 140 and 150 allows different air outlet effects to be achieved in the cooling mode or heating mode of the air conditioner, effectively rectifying the airflow under different operating conditions and improving the air output and temperature control effect of the air conditioner.

[0048] Referring to Figure 2 , the first and second air deflectors 140, 150 jointly seal the air outlet 124. This improves the appearance of the air conditioner and reduces the apparent gap compared to using a single air deflector to seal the air outlet 124. A single air deflector, limited by manufacturing and assembly process errors, creates a large apparent gap between the air outlet 124 and the air deflector in both the closed and activated states. The provision of the first and second air deflectors 140, 150 not only addresses this appearance issue but also allows for different airflow effects in the air conditioner's cooling and heating modes, improving both airflow volume and temperature control.

[0049] It should be noted that rotation means that the first air guide plate 140 and the second air guide plate 150 rotate around the center of the circle to cooperate in closing the air outlet 124; or, the opening of the air outlet 124 is changed, thereby controlling the airflow blown out from the air outlet 124.

[0050] The opening of the air outlet 124 refers to the process from when the air outlet 124 is completely blocked by the first air guide plate 140 and the second air guide plate 150 to when it is exposed. The more area of ​​the air outlet 124 is exposed, the larger the opening of the air outlet 124 is, and vice versa.

[0051] Specifically, the circumferential extension length of the first air guide plate 140 is greater than the circumferential extension length of the second air guide plate 150. The air guide assembly 130 further includes a louvered wind sweeping device, which is mounted on the first air guide plate 140. The first air guide plate 140 is longer than the second air guide plate 150. The louvered wind sweeping device functions to adjust the airflow horizontally and vertically. Mounting the louvered wind sweeping device on the first air guide plate 140 provides greater structural strength for the first air guide plate 140, thereby extending the service life of the air conditioner. Furthermore, the louvered wind sweeping device and the first air guide plate 140 are more convenient to install. When closed, the first air guide plate 140 effectively shields the louvered wind sweeping device, improving the product's appearance.

[0052] Furthermore, the outer surfaces of the first air guide plate 140 and the second air guide plate 150 on the side away from the louver sweeping device are both arc-shaped, and the center of the circle on which the outer surface is located coincides with the rotation center of the first air guide plate 140 and the second air guide plate 150. The center of the outer arc of the existing air guide plate does not coincide with its rotation center, which results in a large appearance gap in the closed state and the start-up state. In addition, when the air is blown out from the air outlet 124, air leakage is likely to occur, and turbulence is generated at the air guide plate, affecting the air outlet effect. It can be imagined that the air outlet 124 is usually a rectangular cross-section, while the movement trajectory of the first air guide plate 140 and the second air guide plate 150 is a circle. In this way, the circle is placed in the rectangle, and the first air guide plate 140 and the second air guide plate 150 can be closer to the cavity wall of the air outlet 124, so that they can be regarded as part of the air outlet 124, reducing the problem of air leakage and improving the problem of large appearance gap affecting the appearance.

[0053] Referring to Figures 2 to 6, in order to further solve the problems of air leakage and appearance, one side of the air duct 120 includes a volute tongue section 121 and an air outlet section 122 connected to the volute tongue section 121, and the air guide assembly 130 is correspondingly arranged at the air outlet section 122. The part of the air outlet section 122 close to the air outlet 124 is suitable for bending to form an arc-shaped avoidance portion 123, and the first air guide plate 140 and the second air guide plate 150 can be rotatably placed at the arc-shaped avoidance portion 123.

[0054] The volute tongue section 121 and the air outlet section 122 are parts of the face frame 112 that constitute the air duct 120. As mentioned above, the outer surfaces of the first air guide plate 140 and the second air guide plate 150 are arc-shaped. In this way, when the first air guide plate 140 and the second air guide plate 150 are located in the arc-shaped avoidance portion 123, they are equivalent to being regarded as parts connected to the volute tongue section 121 to form the air duct 120. In this way, the problem of air leakage during the heating process or the cooling process can be solved, and the problem of large appearance gaps can also be overcome.

[0055] Specifically, the louvered wind sweeping device includes a louvered wind sweeping structure 160. The louvered wind sweeping structure 160 has multiple wind sweeping blades spaced apart and swingable along the rotation axis of the first wind guide plate 140. The louvered wind sweeping structure 160 engages with the first wind guide plate 140. The wind sweeping blades include blades for vertical and horizontal wind directions, which are connected in series by a tie rod. During operation, they are driven by a motor to swing vertically or horizontally.

[0056] Referring to Figure 2 , the wind sweeping blades are mounted on the first wind guide plate 140. To control the weight of the first wind guide plate 140 and facilitate its installation, in one embodiment, the first wind guide plate 140 is hollow. A slot 141 is provided in the middle of the first wind guide plate 140. The louver wind sweeping structure 160 is provided with a buckle 161 corresponding to the slot 141, and the buckle 161 engages the slot 141. Compared to providing the slot 141 on the louver wind sweeping structure 160, the hollow first wind guide plate 140 facilitates the placement of the slot 141. Furthermore, the hollow first wind guide plate 140 provides space for deformation, making the buckle 141 provided on the first wind guide plate 140 more convenient for engagement.

[0057] In this way, by using a hollow air guide plate, the structural strength of the first air guide plate 140 is improved while the weight of the first air guide plate 140 is reduced; the first air guide plate 140 and the louver wind sweeping structure 160 are connected by a clip-on method, which reduces the number of screws, thereby ensuring stability while improving the efficiency of the installation process.

[0058] In another embodiment, the first air guide plate 140 is an arc-shaped curved plate.

[0059] Referring to Figure 2, further, in order to improve the structural strength and facilitate installation, the first air guide plate 140 extends inward from the edge of the slot 141 to form a reinforcing rib 142. Under the action of external force, the reinforcing rib 142 can abut against the hollow cavity wall of the first air guide plate 140. A plurality of card slots 141 are provided in the length direction of the first air guide plate 140, for example, at the end and / or middle position. During installation, because the first air guide plate 140 is hollow, when the buckle 161 is pressed against the card slot 141, the side of the first air guide plate 140 where the card slot 141 is located will be deformed and recessed inward. In this process, due to the length of the first air guide plate 140, deformation in the middle position may be more likely to cause a weaker installation force point. Therefore, a reinforcing rib 142 is provided in the card slot 141, which abuts against the hollow cavity wall when deformed to provide reverse support force, thereby facilitating installation and improving the structural strength of the card connection position. In this way, during the subsequent disassembly process, the stability of the subsequent installation will not be affected by the deformation of the notch of the card slot 141.

[0060] To further enhance the airflow and temperature control performance of the air conditioner, the first air guide plate 140 has a concave curved surface on the side facing the louvered air sweeping device, while the second air guide plate 150 has a convex curved or flat surface on the side facing the louvered air sweeping device. The concave curved surface of the first air guide plate 140 and the convex curved or flat surface of the second air guide plate 150 guide the airflow. By coordinating the positions of the first and second air guide plates 140, 150, different airflow effects can be achieved in cooling and heating modes, improving the airflow and temperature control performance of the air conditioner.

[0061] The first air guide plate 140 is longer than the second air guide plate 150, and the concave arc surface of the first air guide plate 140 guides the airflow, and the convex curved surface or plane of the second air guide plate 150 also guides the airflow. The direction of the airflow passing through the first air guide plate 140 is the same as that of the concave arc surface, and the convex curved surface or plane of the second air guide plate 150 has an adsorption effect on the airflow, so that when the first air guide plate 140 is located in the arc-shaped avoidance portion 123, the airflow will be deflected downward.

[0062] On the contrary, when the first air guide plate 140 is below and the second air guide plate 150 is above, that is, the arc-shaped avoidance portion 123, the first air guide plate 140 is longer than the second air guide plate 150, so that the air flow can be transported farther, thereby increasing the air guide range and improving the comfort of air supply.

[0063] The air conditioning indoor unit 100 has different air outlet modes according to the sizes of the air outlets 124 opened by the first air guide plate 140 and the second air guide plate 150 in the cooling mode or the heating mode.

[0064] 3 , specifically, in the heating mode, the air-conditioning indoor unit 100 includes a first air outlet mode. In the first air outlet mode, the first air guide plate 140 is located at the arc-shaped avoidance portion 123, and the second air guide plate 150 is located on the other side of the air duct 120. The first air guide plate 140 and the second air guide plate 150 form a first opening 131 and a second opening 132 closer to the air outlet 124 in the outflow direction of the airflow, and the first opening 131 and the second opening 132 are similar in size.

[0065] It should be noted that the similar sizes of the first opening 131 and the second opening 132 here means that in the flow direction of the airflow, the sizes of the openings at both ends of the channel between the first air guide plate 140 and the second air guide plate 150 are almost the same. For example, the difference between the area of ​​the first opening 131 and the area of ​​the second opening 132 is not greater than 0.1 mm2.

[0066] In the first mode, hot air passes through the first air guide plate 140 and the second air guide plate 150 from the air duct 120. Since the length of the first air guide plate 140 is greater than that of the second air guide plate 150, a downward gap is formed between the first air guide plate 140 and the second air guide plate 150. The outer surface of the first air guide plate 140 is suitable for being placed in the arc-shaped avoidance portion 123, and no air leakage problem will occur. The inner surface of the first air guide plate 140 is a concave arc surface, and the outer surface of the second air guide plate 150 is a convex curved surface or plane. In this way, the air flow generates an adsorption effect through the second air guide plate 150, and is guided to the gap through the first air guide plate 140 and remains. The hot air can sink better along the wall, so that the heating air volume can be increased, the air supply angle is larger, and the air supply effect is better.

[0067] 4 , in the heating mode, the air-conditioning indoor unit 100 includes a second air outlet mode. In the second air outlet mode, the first air guide plate 140 is located at the arc-shaped avoidance portion 123, and the second air guide plate 150 is located on the other side of the air duct 120. The first air guide plate 140 and the second air guide plate 150 form a first opening 131 and a second opening 132 closer to the air outlet 124 in the outflow direction of the airflow. The first opening 131 is larger than the second opening 132.

[0068] Since the length of the first air guide plate 140 is greater than that of the second air guide plate 150, a downward gap is formed between the first air guide plate 140 and the second air guide plate 150. The outer surface of the first air guide plate 140 is suitable for being placed in the arc-shaped avoidance portion 123, and no air leakage problem will occur. The inner surface of the first air guide plate 140 is a concave arc surface, and the outer surface of the second air guide plate 150 is a convex curved surface or plane. In this way, the air flow through the second air guide plate 150 produces an adsorption effect, and the first opening 131 and the second opening 132 form a trumpet mouth with a larger inner side and a smaller outer side. In this way, the hot air is concentrated and blown out from the second opening 132, forming a fixed-point concentrated heat supply, which can quickly perform heating. For example, the air-conditioning indoor unit 100 is provided with an infrared sensor to monitor the position of human activities. The first air guide plate 140 rotates toward the arc-shaped avoidance portion 123 to a specific position or a specific angle, and the second air guide plate 150 rotates in the opposite direction to a specific position or a specific angle. At the same time, the air-sweeping blades of the louver air-sweeping device swing according to the position of human activities, thereby realizing fixed-point rapid heating and improving the user experience.

[0069] 5 , in cooling mode, the air-conditioning indoor unit 100 includes a third air outlet mode. In the third air outlet mode, the second air guide plate 150 is located at the arc-shaped avoidance portion 123, and the first air guide plate 140 is located on the other side of the air duct 120. The first air guide plate 140 and the second air guide plate 150 form a first opening 131 and a second opening 132 closer to the air outlet 124 in the outflow direction of the airflow, and the first opening 131 and the second opening 132 are similar in size. Since the length of the first air guide plate 140 is greater than that of the second air guide plate 150, the length of the arc-shaped avoidance portion 123 is greater than that of the second air guide plate 150, and the length of the arc-shaped avoidance portion 123 is slightly greater than or equal to the length of the first air guide plate 140, the outer surface of the second air guide plate 150 is suitable for being placed at the arc-shaped avoidance portion 123, and no air leakage problem will occur. In this way, the first air guide plate 140 is equivalent to cooperating with the arc-shaped avoidance portion 123 to form the air outlet section 122, and the inner surface of the first air guide plate 140 is a concave arc surface, and the outer surface of the second air guide plate 150 is a convex curved surface or plane. In this way, the air flow generates an adsorption effect through the second air guide plate 150, and the first opening 131 and the second opening 132 are of similar size. In this way, in the cooling mode, the cooperation of the first air guide plate 140 and the second air guide plate 150 makes the cold air outlet smooth, the air volume attenuation is small, the air supply range is wider, and the user experience is better.

[0070] Referring to Figure 6 , in cooling mode, the air conditioner indoor unit 100 includes a fourth air outlet mode. In this fourth air outlet mode, the second air guide plate 150 is located at the curved avoidance portion 123, and the first air guide plate 140 is located on the other side of the air duct 120. The first and second air guide plates 140 and 150 form a first opening 131 and a second opening 132 closer to the air outlet 124 in the outflow direction. The first opening 131 is larger than the second opening 132. The first and second openings 131 and 132 form a bell-shaped opening that is larger inside and smaller outside. This allows cold air to be concentrated and blown out from the second opening 132, achieving targeted centralized cooling and rapidly delivering cold air. For example, the air conditioner indoor unit 100 is equipped with an infrared sensor to monitor the location of human activity. The second air guide plate 150 rotates toward the curved avoidance portion 123 to a specific position or angle, while the first air guide plate 140 rotates in the opposite direction to a specific position or angle. Simultaneously, the air sweeping blades of the louvered air sweeping device swing according to the location of the person, achieving targeted, rapid heating and improving the user experience.

[0071] In this way, the present application can achieve different air outlet effects in the cooling mode or heating mode of the air conditioner through the setting of the first air guide plate 140 and the second air guide plate 150. The setting of the inner and outer surfaces of the first air guide plate 140 and the second air guide plate 150 can optimize the air guide effect, and the setting of the arc-shaped avoidance portion 123 of the air outlet section 122 can solve the air leakage and appearance gap problems of the first air guide plate 140 and the second air guide plate 150, avoid matching the different lengths of the first air guide plate 140 and the second air guide plate 150, and realize effective rectification of the airflow under different working conditions, thereby improving the air output and temperature control effect of the air conditioner.

[0072] Hot or cold air blown out of the air conditioner indoor unit 100 can be blown into the room through the air outlet 124. The air guide assembly 130 is disposed at the air outlet 124. The first and second air guide plates 140, 150 can be rotated to close the air outlet 124 or change the opening of the air outlet 124, thereby guiding the airflow from the air outlet 124. The first and second air guide plates 140, 150 jointly close the air outlet 124. Compared to using a single air guide plate to close the air outlet, this can improve the appearance of the air conditioner and reduce the size of the apparent gap. A single air shield is limited by the manufacturing process and errors during the assembly process, resulting in a large apparent gap between the air outlet 124 and the air outlet 124 in the closed and activated states. The provision of the first and second air guide plates 140, 150 not only solves the appearance problem but also enables different air outlet effects in the cooling mode or heating mode of the air conditioner, thereby improving the air output and temperature control effect of the air conditioner.

[0073] When making a specific selection, the user can select the required mode through the remote control or APP, that is, select the first mode, second mode, third mode or fourth mode. In other words, in cooling mode and heating mode, there are two different air outlet modes: fast and normal.

[0074] In cooling mode (heating operates on the same principle), the air conditioner first draws in a large amount of air from the room, passes it through the filter, and enters the evaporator. Simultaneously, the compressor operates, converting the refrigerant into a high-pressure gas. This high-pressure gaseous refrigerant passes through the outdoor unit's condenser, converting it into a high-pressure liquid while releasing a significant amount of heat. The high-pressure liquid then passes through a throttling device, converting it into a low-temperature, low-pressure liquid before entering the indoor unit's evaporator. The low-temperature, low-pressure refrigerant evaporates, absorbing heat. This lowers the temperature of the air entering the evaporator and is blown out through the fan blades, thereby cooling the room.

[0075] 7 to 10 , the following describes the assembly of the first and second air guide plates 140 and 150 .

[0076] The first air guide plate 140 and the second air guide plate 150 are driven respectively by two driving motors 180. The drive of the louver sweeping device can be combined with the drive motors 180 of the first air guide plate 140 and the second air guide plate 150. For example, the drive motor 180 of the first air guide plate 140 drives the swing of the vertical sweeping blades, and the drive motor 180 of the second air guide plate 150 drives the swing of the horizontal sweeping blades. The drive of the louver sweeping device can also be driven by a separate drive motor 180.

[0077] Specifically, first lugs 143 are provided at both ends of the first air deflector 140. Both first lugs 143 are provided with first rotating shafts 144, and the two first rotating shafts 144 are oriented in the same direction. Second lugs 151 are provided at both ends of the second air deflector 150. First shaft holes 152 are provided in the second lugs 151 corresponding to the first rotating shafts 144, and the first rotating shafts 144 are inserted into the first shaft holes 152. In this way, the first air deflector 140 and the second air deflector 150 can rotate concentrically when driven by different drive motors 180.

[0078] As shown in Figure 9, the two first lugs 143 of the first air guide plate 140 and the two second lugs 151 of the second air guide plate 150 are arranged in sequence, that is, the connection method is AB, AB. Starting from the left side facing the direction of Figure 9, the first lug 143 is connected to the second lug 151, and the right side is also the first lug 143 connected to the second lug 151. The first lugs 143 are both located on the left side, so that the first air guide plate 140 and the second air guide plate 150 are easier to assemble.

[0079] Furthermore, in order to ensure that the first air guide plate 140 and the second air guide plate 150 are stable and not prone to shaking, thereby ensuring the air guiding effect in the cooling mode or the medium heating mode, the air guide assembly 130 also includes an air guide bracket 170, and mounting cylinders 171 are provided at both ends of the air guide bracket 170. The two mounting cylinders 171 are provided with hollow second axial holes 172 protruding from the middle part; the periphery of the first axial hole 152 is protruded in the direction toward the first lug 143 to form a second rotating shaft 153, and the second rotating shaft 153 is inserted into the second axial hole 172. During installation, the air guide bracket 170 is installed on the chassis 111 of the air-conditioning indoor unit 100, and the first air guide plate 140 is placed in the second shaft hole 172 of the air guide bracket 170 through the second rotating shaft 153 of the first lug 143, and the second air guide plate 150 is connected to the first rotating shaft 144 of the first air guide plate 140 through the first shaft hole 152 of the second lug 151, so that the first lug 143 and the second lug 151 are both located at the mounting cylinder 171, and the first shaft hole 152 and the second shaft hole 172 are set in the same way. The driving shaft of the driving motor 180 can pass through the middle and connect the first air guide plate 140 and the second air guide plate 150 respectively, so that the first air guide plate 140 and the second air guide plate 150 can achieve concentric rotation under the drive of different driving motors 180.

[0080] The air guide bracket 170 is connected to the chassis 111 by a snap-on connection, which makes installation more convenient. Compared with directly installing the air guide assembly 130 and the louver wind sweeping device on the chassis 111, the setting of the air guide bracket 170 makes the structure more stable, the interference between the first air guide plate 140 and the second air guide plate 150 is smaller, and the movement is smoother.

[0081] In order to reduce the rotational friction between the first air guide plate 140 and the second air guide plate 150, reduce interference, make the rotation smoother, and increase the service life of the first air guide plate 140 and the second air guide plate 150, the fitting clearance between the second rotating shaft 153 of the second lug 151 of the second air guide plate 150 and the second axial hole 172 of the air guide bracket 170 is smaller than the fitting clearance between the first axial hole 152 of the second air guide plate 150 and the first rotating shaft 144 of the first lug 143 of the first air guide plate 140. This can reduce the rotational friction between the first air guide plate 140 and the second air guide plate 150, weaken the mutual rotational influence, and make the rotation smoother.

[0082] Specifically, the air guide assembly 130 also includes two drive motors 180, one drive motor 180 is arranged in a mounting cylinder 171, one drive motor 180 drives the first air guide plate 140, and the other drive motor 180 drives the second air guide plate 150. The drive motor 180 is arranged in the mounting cylinder 171. On the one hand, it can hide the drive motor 180, and on the other hand, it can also protect the drive motor 180 to avoid interference.

[0083] Furthermore, in order to ensure more stable rotation of the first air guide plate 140 and the second air guide plate 150 and better stability when guiding the wind, and to reduce noise generation, the first air guide plate 140 is further provided with a connecting lug 145 between the two first lugs 143, and a connecting shaft hole 146 is provided on the connecting lug 145. The second air guide plate 150 is further provided with a mounting lug 154 between the two second lugs 151, and a mounting shaft 155 is provided on the mounting lug 154, which cooperates with the connecting shaft hole 146.

[0084] The connecting lug 145 is arranged in the middle position of the first air guide plate 140, and the extension direction of the installation shaft 155 is toward the length direction of the first air guide plate 140. In this way, after being embedded in the installation shaft hole during installation, the interference with the first air guide plate 140 and the second air guide plate 150 in the length direction is small, and it can also play the role of pre-fixing the first air guide plate 140 and the second air guide plate 150, which is convenient for the subsequent assembly of the first air guide plate 140 and the second air guide plate 150 and the air guide bracket 170. In this way, only one set of mounting lugs 154 and connecting lugs 145 are needed to play a transmission and connection role in the middle of the first air guide plate 140 and the second air guide plate 150, which can ensure that the rotation of the first air guide plate 140 and the second air guide plate 150 is more stable and the stability when playing the wind guiding role is better, reducing noise generation and will not reduce the air supply effect.
