Description

Technical Field

[0001] This application relates to the field of air conditioner technology, and for example, to an air conditioner. Background Technology

[0002] Currently, air conditioners have become an indispensable appliance, widely used in homes, businesses, and transportation, among other fields. Related technology discloses an air conditioner including a casing and multiple centrifugal fans. The casing has an air inlet and an air outlet, and the multiple centrifugal fans are respectively installed in corresponding volutes, arranged adjacent to each other along the length of the air outlet, and supplying air into the room through the air outlet.

[0003] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art:

[0004] Multiple centrifugal fans are arranged adjacent to each other and exhaust air through a single air outlet, resulting in dead zones in air supply and a single air supply method.

[0005] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0006] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.

[0007] This disclosure provides an air conditioner that solves the problems of dead airflow areas and a single airflow method in air conditioners.

[0008] In some embodiments, the air conditioner includes:

[0009] The casing is provided with a first air outlet and a second air outlet, and the first air outlet is provided with a first air guide plate and the second air outlet is provided with a second air guide plate.

[0010] A fan assembly, housed within a casing, includes a cross-flow fan; and a first air outlet and a second air outlet are arranged adjacent to each other along the axial direction of the cross-flow fan.

[0011] The air conditioner provided in this disclosure can achieve the following technical effects:

[0012] Compared to using multiple centrifugal fans, using a cross-flow fan results in a thinner overall casing and a wider airflow range without dead zones. Because the two air outlets (the first and second outlets) are arranged adjacent to each other along the axis of the cross-flow fan, the cross-flow fan, in conjunction with the first and second outlets, ensures more even airflow. Since both outlets are equipped with guide vanes, various airflow patterns can be achieved by adjusting the rotation angle of the two guide vanes (the first and second vanes). This allows the air conditioner to be suitable for more user scenarios and improves the user experience.

[0044] The term "and / or" describes an association between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or A and B.

[0045] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0046] This disclosure provides an air conditioner that can be horizontally suspended from the ceiling for use, as shown in the following embodiments. Figure 1 As shown in (a), it can also be installed vertically on the ground for use, such as Figure 1 As shown in (b), it is also called a drop crane.

[0047] This disclosure also provides an air conditioner, including a housing 100 and a fan assembly. The housing 100 has a first air outlet 110 and a second air outlet 120, and the first air outlet 110 has a first air guide plate 111, and the second air outlet 120 has a second air guide plate 121. The fan assembly is disposed within the housing 100 and includes a cross-flow fan 140. Furthermore, the first air outlet 110 and the second air outlet 120 are arranged adjacent to each other along the axial direction of the cross-flow fan 140.

[0048] In this embodiment, compared to using multiple centrifugal fans, using a cross-flow fan 140 results in a thinner overall casing 100 and a wider air delivery range without dead zones. Since the two air outlets (first air outlet 110 and second air outlet 120) are arranged adjacent to each other along the axial direction of the cross-flow fan 140, the cross-flow fan 140, in conjunction with the first air outlet 110 and the second air outlet 120, ensures more uniform airflow. Because both air outlets are equipped with guide vanes, various air delivery methods can be achieved by adjusting the rotation angle of the two guide vanes (first guide vane 111 and second guide vane 121). This allows the air conditioner to be suitable for more user scenarios and improves the user experience.

[0049] Optionally, the fan assembly also includes a volute 150 and a fan motor 141. The volute 150 houses the cross-flow fan 140. The fan motor 141 is located outside the volute 150, and its drive shaft passes through the volute 150 and is connected to the cross-flow fan 140. This arrangement facilitates increasing the length of the cross-flow fan 140 itself.

[0050] Optionally, such as Figure 2 As shown, the volute portion 150 includes a volute side plate 153, and the housing 100 includes a housing side plate 103, with the volute side plate 153 and the housing side plate 103 arranged opposite to each other. Figure 2 As shown, a mounting side plate 104 is provided between the volute side plate 153 and the housing side plate 103, forming a heat dissipation area with a heat dissipation vent 1032. The first side of the fan motor 141 is fixed to the volute side plate 153, and the second side of the fan motor 141 passes through the mounting side plate 104 and is located within the heat dissipation area.

[0051] In this embodiment, a volute side plate 153 is provided on the left and right sides of the volute portion 150, and a housing side plate 103 is provided on the left and right sides of the housing 100. For example, a mounting side plate 104 is provided between the volute side plate 153 and the housing side plate 103 located on the left side. The mounting side plate 104 has a mounting hole, through which the second side of the fan motor 141 extends into the heat dissipation area. External air can enter and exit the heat dissipation area through the heat dissipation port 1032, thereby dissipating heat from the fan motor 141.

[0052] Optionally, the volute side plate 153 is provided with a motor support 142, which has multiple sets of fixing holes for fixing fan motors 141 of different sizes. This facilitates the installation of different models of fan motors 141 and improves compatibility. For example, the motor support 142 has two sets of fixing holes, one set for fixing a small-sized fan motor 141 and the other set for fixing a large-sized fan motor 141.

[0053] Optionally, the housing 100 includes a housing base plate 101, which includes a first plate segment 1011 and a second plate segment 1012. A first end of the first plate segment 1011 is connected to a first end of the second plate segment 1012, and a second end of the second plate segment 1012 extends toward the first air outlet 110. The volute portion 150 includes a first volute 151, the first end of which extends to the first end of the second plate segment 1012, as shown below. Figure 3 As shown. The first volute 151 and the second plate segment 1012 form the air supply sidewall 154. Air from the volute portion 150 can flow along the air supply sidewall 154 to the first air outlet 110, as shown. Figure 4 As shown.

[0054] In this embodiment, the volute portion 150 is enclosed by a first volute 151, a second volute 152, and two volute side plates 153, wherein the first volute 151 is located on the upper side, the second volute 152 is located on the lower side, and the two volute side plates 153 are located on the left and right sides respectively. Figure 5 As shown. The first volute 151 and the second plate segment 1012 form the air supply sidewall 154, reducing the length of the first volute 151 and lowering the cost of the volute section 150. The air supply sidewall 154 serves as part of the air supply duct of the air conditioner. The air generated by the volute section 150 flows along the first volute 151 to the second plate segment 1012, that is, along the air supply sidewall 154, and then flows to the first air outlet 110.

[0055] Optionally, the housing 100 further includes a housing top plate 102, which is arranged opposite to the housing bottom plate 101. The volute portion 150 further includes a second volute 152, the first end of which extends toward the housing top plate 102. Figure 4 As shown, a bracket 155 is provided inside the volute 150. The first end of the bracket 155 is connected to the second plate segment 1012, and the second end of the bracket 155 is connected to the second volute 152.

[0056] In this embodiment, when the air conditioner is suspended for use, the bottom plate 101 of the casing is located above and the top plate 102 of the casing is located below, such as... Figure 1 As shown in (a). During the production and assembly of the air conditioner, the bottom plate 101 of the casing is located below and the top plate 102 of the casing is located above, and... Figure 1 (a) shows the opposite vertical direction. Since the air supply sidewall 154, which is composed of the first volute 151 and the second plate segment 1012, is relatively long, the support 155 can be provided to prevent the air supply sidewall 154 from sagging.

[0057] Optionally, such as Figure 5 As shown, the bracket 155 has a cutout 1551 in the middle. The cutout 1551 helps to reduce wind resistance.

[0058] Optionally, such as Figure 6 As shown, the first air outlet 110 is also provided with a first sway vane 112, and the second air outlet 120 is also provided with a second sway vane 122, and the first sway vane 112 and the second sway vane 122 can be independently controlled in terms of swing angle. The first sway vane 112 is located inside the first air guide plate 111 and is used to sweep air left and right at the first air outlet 110. The second sway vane 122 is located inside the second air guide plate 121 and is used to sweep air left and right at the second air outlet 120.

[0059] In some embodiments, the air conditioner further includes a radar module and a controller. The radar module is used to monitor the number and location information of users. The controller is electrically connected to the radar module and is configured to control the rotation angle of the first air guide plate 111 and the second air guide plate 121, and the swing angle of the first swivel 112 and the second swivel 122 based on the number and location information.

[0060] In this embodiment, optionally, when the radar module detects that the number of users is zero, the controller clears the quantity and location information. Optionally, when the radar module detects that the number of users is not zero, it acquires the user's location. If a direct-blow command is received, the controller adjusts the rotation angles of the two air guides and the two oscillating blades so that the air from both air outlets does not blow directly onto the user. If a direct-blow command is received, the controller adjusts the rotation angles of the two air guides and the two oscillating blades so that the air from both air outlets blows directly onto the user. If no command is received, the controller clears the quantity and location information.

[0061] In some embodiments, the air conditioner further includes a thermopile module and a controller. The thermopile module is used to monitor the user's temperature information. The controller is electrically connected to the thermopile module and is configured to control the rotation angle of the first air guide plate 111 and the second air guide plate 121, and the swing angle of the first swivel blade 112 and the second swivel blade 122 according to the temperature information.

[0062] In this embodiment, optionally, when the thermopile module detects that the user's temperature information is outside the comfortable range, the controller adjusts the rotation angle of the two air guides and the two oscillating blades so that the air from both air outlets does not blow directly on the user. Simultaneously, the controller reduces the airflow. For example, when the air conditioner is cooling, if the user's temperature information is below the comfortable range, the air will not blow directly on the user, improving the user experience.

[0063] In scenarios where air conditioners are floor-mounted, users frequently adjust the first air guide vane 111 and the second air guide vane 121 manually during use, which may lead to the two vanes being adjusted to abnormal airflow angles. This results in abnormal airflow resistance at the corresponding air outlet, which does not match the airflow resistance at the air inlet 130, causing surging and noise. Adjusting the air guide vanes also causes synchronous pressure changes at the air outlet, easily creating vortices and generating noise. Furthermore, when the volute pressure in the volute section 150 increases, the volute airflow increases, or the heat exchanger 500 becomes clogged, vortices can also easily form within the volute section 150, generating noise as well.

[0064] This disclosure also provides an air conditioner with a noise-reducing louver assembly 200, including a housing 100, a fan assembly, and the noise-reducing louver assembly 200. The fan assembly is disposed within the housing 100 and includes a volute portion 150. The volute portion 150 includes two opposing volute side plates 153, and exhaust ports 1531 are provided on the volute side plates 153. Figure 7 and Figure 8 As shown, the noise reduction louver assembly 200 is movably disposed at the exhaust port 1531 to avoid the exhaust port 1531 so as to discharge airflow and reduce noise, or to block the exhaust port 1531 so as to keep the volute side plate 153 closed.

[0065] In this embodiment, noise is generated when turbulent airflow occurs within the volute 150, creating eddies. At this time, the noise-reducing louver assembly 200 avoids the exhaust port 1531, allowing the eddies to be discharged through the exhaust port 1531 to the outside of the volute 150, thereby reducing noise. When the volute 150 is discharging air smoothly, the noise-reducing louver assembly 200 blocks the exhaust port 1531, keeping the volute side plate 153 sealed to prevent air leakage, thus ensuring the airflow efficiency of the volute 150. In this way, the noise of the air conditioner can be effectively reduced by the noise-reducing louver assembly 200, improving the user experience.

[0066] Optionally, such as Figure 8 As shown, the noise-reducing louver assembly 200 includes a noise-reducing connecting rod 210, a noise-reducing motor 230, and multiple noise-reducing louvers 220. The multiple noise-reducing louvers 220 are evenly connected to the noise-reducing connecting rod 210 along its extension direction. A noise-reducing swing arm 231 is mounted on the drive shaft of the noise-reducing motor 230 and is connected to the noise-reducing connecting rod 210. When the noise-reducing motor 230 rotates, it drives the noise-reducing connecting rod 210 to move via the noise-reducing swing arm 231. When the noise-reducing connecting rod 210 moves, it drives all the noise-reducing louvers 220 to rotate synchronously.

[0067] In this embodiment, the noise-reducing louver 220 has a first shaft at each end and a second shaft at one end. The two first shafts are hinged together, and the second shaft is parallel to the first shafts and connected to the noise-reducing connecting rod 210. Thus, when the noise-reducing connecting rod 210 moves, it drives the noise-reducing louver 220 to rotate around the first shaft via the second shaft.

[0068] Optionally, such as Figure 9 As shown, the noise-reducing louver 220 has a first stepped surface 221 on its first side and a second stepped surface 222 on its second side. Furthermore, when the noise-reducing louver 220 is closed, the first stepped surface 221 and the second stepped surface 222 of adjacent noise-reducing louvers 220 overlap. In this way, the overlapping and cooperation of the first stepped surface 221 and the second stepped surface 222 improves the blocking effect on the exhaust port 1531 when the noise-reducing louver 220 is closed.

[0069] Optionally, a cross-flow fan 140 is provided inside the volute 150, with two volute side plates 153 located on opposite sides of the cross-flow fan 140 along its axial direction. This design, using a cross-flow fan 140, allows for a wider airflow range and eliminates dead zones.

[0070] Optionally, such as Figure 7 As shown, a heat exchanger 500 is also provided inside the casing 100. The heat exchanger 500 is located at the volute outlet of the volute section 150, and the exhaust port 1531 is opened on the volute side plate 153 near the heat exchanger 500.

[0071] In this embodiment, the volute 150 is adapted to the cross-flow fan 140, and the vortices generated by the cross-flow fan 140 are typically located on both sides of the volute 150. Furthermore, since the heat exchanger 500 is located at the volute outlet, the vortices tend to accumulate near the heat exchanger 500. Therefore, opening the exhaust port 1531 near the heat exchanger 500 on the volute side plate 153 facilitates the rapid discharge of the vortices.

[0072] In some embodiments, the air conditioner further includes a pressure sensor and a controller. The pressure sensor is used to monitor the volute pressure of the volute portion 150. The controller is electrically connected to the pressure sensor and the noise-reducing motor 230 and is configured to control the noise-reducing louvers 220 to rotate and open via the noise-reducing motor 230 when the volute pressure is greater than or equal to a preset volute pressure.

[0073] In this embodiment, when the volute pressure is greater than or equal to the preset volute pressure, it means that eddies will be generated within the volute section 150. At this time, the controller controls the noise-reducing louvers 220 to rotate and open via the noise-reducing motor 230. Figure 10 As shown in (a), the vortex is released from the exhaust port 1531, thereby reducing the pressure in the volute and thus reducing noise.

[0074] Optionally, the controller is also configured to control the noise-reducing louvers 220 to rotate and close when the volute pressure is lower than a preset volute pressure, such as... Figure 10 As shown in (b). This prevents air leakage after the volute pressure returns to normal, ensuring the air outlet efficiency of the volute section 150.

[0075] Optionally, a heat exchanger 500 is also provided inside the housing 100, and the air conditioner has a self-cleaning mode for cleaning the heat exchanger 500. The controller is also configured to control the air conditioner to start the self-cleaning mode when the volute pressure is greater than or equal to a preset volute pressure.

[0076] In this embodiment, the presence of dirt or blockage can be determined by monitoring the airflow through the heat exchanger 500, or by acquiring and comparing images of the heat exchanger 500. If the increased pressure in the volute 150 is due to dirt or blockage in the heat exchanger 500, opening the noise-reducing louvers 220 simultaneously cleans the heat exchanger 500, allowing air to flow smoothly through the heat exchanger 500 and thus quickly reducing the pressure inside the volute 150.

[0077] In some embodiments, the air conditioner further includes an airflow sensor and a controller. The airflow sensor is used to monitor the airflow in the volute 150. The controller is electrically connected to the airflow sensor and the noise-reducing motor 230, and is configured to control the noise-reducing louvers 220 to rotate and open via the noise-reducing motor 230 when the airflow in the volute is greater than or equal to a preset airflow in the volute.

[0078] In this embodiment, if the air conditioner's airflow reaches the high-speed setting, the large airflow can easily generate eddies and produce noise. When the volute airflow is greater than or equal to the preset volute airflow, it means that eddies will be generated within the volute section 150. At this time, the controller controls the noise-reducing louvers 220 to rotate and open via the noise-reducing motor 230. Figure 10 As shown in (a), vortices are released from exhaust port 1531, thereby reducing noise.

[0079] Optionally, the controller is also configured to control the noise-reducing louvers 220 to rotate and close when the volute airflow is less than a preset volute airflow, such as... Figure 10 As shown in (b). In this way, air leakage can be prevented when the air volume of the volute is normal, ensuring the air outlet efficiency of the volute section 150.

[0080] This disclosure also provides an air conditioner with a noise reduction break assembly 300, including a housing 100 and the noise reduction break assembly 300. An air supply duct is provided inside the housing 100. For example... Figure 11 and Figure 12 As shown, the noise reduction fracture assembly 300 includes a fracture plate 310 with an openable and closable flexible fracture 311. The fracture plate 310 serves as a side plate enclosing the air supply duct, with the first end of the flexible fracture 311 located inside the air supply duct and the second end located outside the air supply duct. When the air pressure in the air supply duct is greater than or equal to a preset air pressure, the flexible fracture 311 deforms and opens towards its second side under pressure, allowing airflow to be discharged to reduce noise. When the air pressure in the air supply duct is less than the preset air pressure, the flexible fracture 311 springs back and closes due to its own flexibility.

[0081] In this embodiment, when the pressure inside the air supply duct is greater than or equal to the preset duct pressure, it means that eddies will be generated inside the air supply duct, thus producing noise. Under the pressure of the duct, the flexible break 311 is compressed and deformed towards its second side. At this time, the flexible break 311 opens, allowing the eddies to be discharged from the flexible break 311, thereby reducing noise and improving the user experience. When the duct pressure of the air supply duct is less than the preset duct pressure, the duct pressure is insufficient to open the flexible break 311, and the flexible break 311 automatically rebounds and closes under its own flexibility. In this way, air leakage can be prevented when the duct pressure is normal, ensuring the air outlet efficiency of the air supply duct.

[0082] Optionally, such as Figure 11 As shown, a heat exchanger 500 is installed in the air supply duct, and the cut plate 310 is located downstream of the heat exchanger 500 along the air outlet direction.

[0083] In this embodiment, the downstream of the heat exchanger 500 is the air outlet (first air outlet 110 and second air outlet 120). Both the duct pressure and the preset duct pressure refer to the pressure of the duct section located between the heat exchanger 500 and the air outlet. When the guide vanes (first guide vane 111 and second guide vane 121) are adjusted, the air outlet resistance changes synchronously, thus affecting the duct pressure. Compared to placing the break plate 310 upstream of the heat exchanger 500, placing it downstream allows for a faster response to changes in the duct pressure of that section. Furthermore, the opening and closing of the flexible break 311 is directly controlled by the duct pressure, resulting in more rapid noise reduction.

[0084] Optionally, a break plate 310 is provided on each side of the heat exchanger 500 along its length. In this embodiment, the length of the heat exchanger 500 is parallel to the axial direction of the cross-flow fan 140, and the two break plates 310 facilitate the rapid discharge of eddies accumulated on both sides of the downstream of the heat exchanger 500.

[0085] Optionally, a cross-flow fan 140 and a heat exchanger 500 are sequentially arranged in the air supply duct along the air outlet direction, and the cut-off plate 310 is located between the cross-flow fan 140 and the heat exchanger 500. In this embodiment, the duct pressure and the preset duct pressure both refer to the pressure of the duct section located between the heat exchanger 500 and the cross-flow fan 140 in the air supply duct.

[0086] Optionally, such as Figure 12 As shown, a recess 312 is provided on the first side of the fracture plate 310, and the flexible fracture surface 311 is located in the recess 312. Under the action of the recess 312, some air can be guided to flow towards the flexible fracture surface 311, which is beneficial for the air to squeeze open the flexible fracture surface 311.

[0087] Optionally, the fracture plate 310 is provided with multiple flexible fractures 311, and the number of flexible fractures 311 gradually increases along the air outlet direction of the air supply duct. In this embodiment, the end of the air outlet direction is the air outlet, and the pressure change at the air outlet is more obvious when the air guide plate rotates. Therefore, providing more flexible fractures 311 is beneficial for quickly discharging eddies.

[0088] Optionally, such as Figure 11 As shown, the housing 100 includes a housing side plate 103, on which a vent hole 1031 is provided. Furthermore, the vent hole 1031 is connected to a flexible break 311, and the airflow discharged when the flexible break 311 is open flows to the outside of the housing 100 through the vent hole 1031. The vent hole 1031 prevents the eddies discharged from the flexible break 311 from remaining in other areas within the housing 100.

[0089] Optionally, a mounting side plate 104 is provided between the fracture plate 310 and the housing side plate 103, and the mounting side plate 104 is provided with a receiving hole 1041. Figure 13 As shown in (a), the receiving hole 1041 corresponds to the flexible fracture surface 311, and the deformed portion of the flexible fracture surface 311 is embedded in the receiving hole 1041 when it is opened. Figure 13 As shown in (b), the flexible fracture surface 311 remains horizontal when closed and does not sink into the receiving hole 1041. In this embodiment, the receiving hole 1041 is a through hole and has no effect on the deformation of the flexible fracture surface 311. Furthermore, the receiving hole 1041 acts as a limit to the deformation of the flexible fracture surface 311, preventing excessive deformation of the flexible fracture surface 311 from causing functional failure.

[0090] Optionally, the cut plate 310 is abutted against the surface of the mounting side plate 104. In this way, the mounting side plate 104 provides support for the cut plate 310, ensuring that the cut plate 310 does not shift when subjected to pressure from the air duct.

[0091] Optionally, there is a gap between the mounting side plate 104 and the housing side plate 103. This gap helps to reduce vibration transmission and lower noise.

[0092] This disclosure also provides an air conditioner with an air intake regulating assembly 400, including a housing 100 and the air intake regulating assembly 400. The housing 100 is provided with an air inlet 130 and a first air outlet 110. Figure 14 and Figure 15 As shown, the air intake adjustment component 400 is movably disposed at the air intake 130 to block or avoid the air intake 130 in order to adjust the air intake resistance, thereby matching the air intake resistance with the air outlet resistance of the first air outlet 110.

[0093] In this embodiment, the air intake resistance is increased when the air intake adjustment component 400 blocks the air intake 130, and decreased when the air intake adjustment component 400 avoids the air intake 130. In this way, by adjusting the air intake resistance using the air intake adjustment component 400, the air intake resistance and exhaust resistance are matched, avoiding the problem of surge and noise caused by the mismatch between the air intake and exhaust resistance, thus improving the user experience.

[0094] Optionally, such as Figure 14 As shown, the air intake adjustment assembly 400 includes an air intake connecting rod 410, an air intake motor 430, and multiple air intake louvers 420. The multiple air intake louvers 420 are evenly connected to the air intake connecting rod 410 along its extension direction. An air intake swing rod 431 is mounted on the drive shaft of the air intake motor 430 and is connected to the air intake connecting rod 410. When the air intake motor 430 rotates, it drives the air intake connecting rod 410 to move via the air intake swing rod 431. When the air intake connecting rod 410 moves, it drives all the air intake louvers 420 to rotate synchronously. Thus, the rotation angle of the air intake louvers 420 is controlled by the air intake motor 430.

[0095] Optionally, such as Figure 14 As shown, the air inlet louver 420 includes a connecting shaft 423, a first louver section 421 and a second louver section 422 that are parallel to each other. The first end of the connecting shaft 423 is connected to the first end of the first louver section 421, and its second end is connected to the first end of the second louver section 422.

[0096] In this embodiment, when using a cross-flow fan 140, the air inlet 130 is relatively long, so the air inlet louvers 420 are two-sectioned. The second end of the first louver section 421 and the second end of the second louver section 422 are respectively provided with a third shaft, and the two third shafts are hinged together. Thus, when the air inlet connecting rod 410 moves, it drives the air inlet louvers 420 to rotate around the third shaft.

[0097] Optionally, such as Figure 14 As shown, a connecting block 424 is provided on the side of the connecting shaft 423, and a mounting shaft 425 is provided on the connecting block 424. The mounting shaft 425 is parallel to the connecting shaft 423 and is connected to the air inlet connecting rod 410. In this way, when the air inlet connecting rod 410 moves, it drives the connecting block 424 to move through the mounting shaft 425, and the connecting block 424 drives the two louver sections to rotate synchronously through the connecting shaft 423.

[0098] Optionally, a cross-flow fan 140 is provided inside the housing 100, and the air inlet louvers 420 are parallel to the axis of the cross-flow fan 140. This helps to provide better shielding and avoidance when the air inlet louvers 420 rotate.

[0099] In some embodiments, the air conditioner further includes an intake air resistance sensor, an outlet air resistance sensor, and a controller. The intake air resistance sensor monitors the intake resistance of the air inlet 130. The outlet air resistance sensor monitors the outlet air resistance of the first outlet 110. The controller is electrically connected to the intake motor 430, the intake air resistance sensor, and the outlet air resistance sensor, and is configured to adjust the rotation angle of the intake louvers 420 via the intake motor 430 based on the outlet air resistance and the intake air resistance. This allows for timely acquisition of changes in intake and outlet air resistance, facilitating rapid adjustment of the intake louvers 420.

[0100] Optionally, the air inlet louver 420 has a first position parallel to the air inlet 130. Furthermore, when the outlet resistance is greater than the inlet resistance, the controller controls the air inlet louver 420 to rotate toward the first position.

[0101] In this embodiment, as Figure 15 As shown in (a), the shading area is maximized when the air inlet louvers 420 are parallel to the air inlet 130, and there are gaps between adjacent air inlet louvers 420, thus ensuring the basic air intake function of the air inlet 130 after shading. When the outlet resistance is greater than the inlet resistance, the controller controls the air inlet louvers 420 to rotate toward the first position, and the air inlet louvers 420 gradually shading the air inlet 130, thereby increasing the inlet resistance. When the inlet resistance increases to match the outlet resistance, the air inlet louvers 420 stop rotating.

[0102] Optionally, such as Figure 15 As shown, the air inlet 130 is provided with an air inlet grille 131, which is arranged perpendicular to the air inlet 130. Each air inlet louver 420 is located between adjacent air inlet grilles 131. Figure 15 As shown in (a), when the air inlet louver 420 is parallel to the air inlet 130, there is a gap between it and the adjacent air inlet grille 131, so as to ensure the basic air intake function of the air inlet 130 after being blocked.

[0103] Optionally, if the rotation angle A of the first air guide plate 111 is less than or equal to 60°, the air inlet louver 420 is controlled to rotate to the first position.

[0104] In this embodiment, the first air guide plate 111 rotates at 0° in the closed position, such as... Figure 15 The position of the first air guide plate 111, indicated by the dashed line, directly affects the outlet resistance. As A decreases, the first air outlet 110 is gradually blocked, causing the outlet resistance to gradually increase. When the outlet resistance increases to a level greater than the inlet resistance, the controller controls the inlet louver 420 to rotate towards the first position. When A decreases to less than or equal to 60°, the inlet louver 420 rotates to the first position, at which point the blocking area is at its maximum. Figure 15 As shown in (a).

[0105] Optionally, the air inlet louver 420 has a second position perpendicular to the air inlet 130. Furthermore, when the outlet resistance is less than the inlet resistance, the controller controls the air inlet louver 420 to rotate toward the second position.

[0106] In this embodiment, the shading area is minimized when the air inlet louver 420 is perpendicular to the air inlet 130. When the outlet resistance is less than the inlet resistance, the controller controls the air inlet louver 420 to rotate toward the second position, gradually avoiding the air inlet 130, thereby reducing the inlet resistance. When the inlet resistance is reduced to match the outlet resistance, the air inlet louver 420 stops rotating.

[0107] Optionally, if the rotation angle A of the first air guide plate 111 is greater than or equal to 120°, the air inlet louver 420 is controlled to rotate to the second position.

[0108] In this embodiment, as A increases, the first air outlet 110 is gradually avoided, causing the air outlet resistance to gradually decrease. When the air outlet resistance decreases to less than the air inlet resistance, the controller controls the air inlet louver 420 to rotate toward the second position. When A increases to greater than or equal to 120°, the air inlet louver 420 rotates to the second position, at which point the obstruction area is minimal, such as... Figure 15 As shown in (b).

[0109] This disclosure also provides a method for controlling an air conditioner, the air conditioner including a housing 100 and an air inlet regulating assembly 400. The housing 100 has an air inlet 130 and a first air outlet 110, and the air inlet regulating assembly 400 is movably disposed at the air inlet 130 to block or avoid the air inlet 130. Figure 16 As shown, the above-mentioned method for controlling an air conditioner includes:

[0110] S10: The controller obtains the air outlet resistance of the first air outlet 110 and the air inlet resistance of the air inlet 130;

[0111] S20: The controller adjusts the position of the air intake adjustment component 400 according to the air outlet resistance and air intake resistance.

[0112] In this embodiment, the controller monitors the intake resistance using an intake air resistance sensor and the outlet air resistance using an outlet air resistance sensor. The intake resistance increases when the intake adjustment component 400 blocks the air inlet 130, and decreases when the intake adjustment component 400 avoids the air inlet 130. In this way, the controller adjusts the intake resistance through the intake adjustment component 400, thereby matching the intake and outlet resistances. This avoids the problem of surge and noise caused by a mismatch between the intake and outlet resistances, improving the user experience.

[0113] Optionally, in step S20, the controller adjusts the position of the air inlet regulating component 400 according to the outlet air resistance and the inlet air resistance, including:

[0114] S21: When the outlet resistance is greater than the inlet resistance, the controller controls the inlet regulating component 400 to partially block the inlet 130.

[0115] S22: When the outlet resistance is less than the inlet resistance, the controller controls the inlet regulating component 400 to partially or completely avoid the inlet 130.

[0116] In this embodiment, when the outlet resistance is greater than the inlet resistance, partially blocking the inlet 130 by the inlet adjustment component 400 increases the inlet resistance, thereby increasing the inlet resistance to match the outlet resistance. Furthermore, partial blocking helps ensure the basic air intake function of the inlet 130. When the outlet resistance is less than the inlet resistance, avoiding the inlet 130 by the inlet adjustment component 400 reduces the inlet resistance, thereby reducing the inlet resistance to match the outlet resistance.

[0117] Optionally, the air inlet regulating assembly 400 includes a plurality of synchronously rotating and spaced air inlet louvers 420, each air inlet louver 420 having a first position parallel to the air inlet 130. Step S21, the controller controls the air inlet regulating assembly 400 to partially block the air inlet 130, including:

[0118] The controller controls the air inlet louvers 420 to rotate toward the first position.

[0119] In this embodiment, the specific structure of the air intake adjustment component 400 is detailed above and will not be repeated here. The air intake louver 420 has the largest obstruction area when it is parallel to the air intake 130, such as... Figure 15 As shown in (a), when the controller controls the air inlet louver 420 to rotate toward the first position, the air inlet louver 420 gradually blocks the air inlet 130, thereby increasing the air inlet resistance. When the air inlet resistance increases to match the air outlet resistance, the air inlet louver 420 stops rotating.

[0120] Optionally, the air inlet louver 420 has a second position perpendicular to the air inlet 130. In step S22, the controller controls the air inlet adjustment assembly 400 to partially or completely avoid the air inlet 130, including:

[0121] The controller controls the air inlet louvers 420 to rotate toward the second position.

[0122] In this embodiment, the obstruction area is minimized when the air inlet louver 420 is perpendicular to the air inlet 130. Figure 15As shown in (b), when the controller controls the air inlet louver 420 to rotate toward the second position, the air inlet louver 420 gradually avoids the air inlet 130, thereby reducing the air inlet resistance. When the air inlet resistance is reduced to match the air outlet resistance, the air inlet louver 420 stops rotating.

[0123] Optionally, the first air outlet 110 is provided with a controllable rotating first air guide plate 111, and the rotation angle of the first air guide plate 111 is denoted as A. The above steps: the controller controls the air inlet louvers 420 to rotate toward the first position, including:

[0124] When A≤a1, the controller controls the air inlet louver 420 to rotate to the first position.

[0125] In this embodiment, as A decreases, the first air outlet 110 is gradually blocked, causing the air outlet resistance to gradually increase. When the air outlet resistance increases to a level greater than the air inlet resistance, the controller controls the air inlet louver 420 to rotate toward the first position. When A decreases to a level less than or equal to a1, the air inlet louver 420 rotates to the first position, at which point the blocking area is at its maximum.

[0126] Optionally, a1 = 60°, such as Figure 15 As shown in (a).

[0127] Optionally, the above step: the controller controls the air inlet louver 420 to rotate toward the second position, including:

[0128] When A≥a2, the controller controls the air inlet louver 420 to rotate to the second position, where a1<a2.

[0129] In this embodiment, as A increases, the first air outlet 110 is gradually avoided, causing the air outlet resistance to gradually decrease. When the air outlet resistance decreases to less than the air inlet resistance, the controller controls the air inlet louver 420 to rotate toward the second position. When A increases to a value greater than or equal to a2, the air inlet louver 420 rotates to the second position, at which point the obstruction area is minimized.

[0130] Optionally, a2 = 120°, such as Figure 15 As shown in (b).

[0131] Optionally, the air conditioner also includes a cross-flow fan 140 disposed within the housing 100. The housing 100 also has a second air outlet 120, which has a controllable rotating second air guide plate 121. The first air outlet 110 and the second air outlet 120 are arranged adjacent to each other along the axial direction of the cross-flow fan 140. Figure 6 As shown. The above steps, after the controller controls the air inlet louvers 420 to rotate towards the second position, also include:

[0132] If the air outlet resistance is still greater than the air inlet resistance after the air inlet louver 420 rotates to the first position, the controller adjusts the rotation angle of the second air guide plate 121.

[0133] In this embodiment, the shading area is maximized after the air inlet louver 420 rotates to the first position. If the air outlet resistance is still greater than the air inlet resistance, the rotation angle of the second air guide plate 121 is adjusted so that the second air outlet 120 cooperates with the first air outlet 110 to discharge air, thereby reducing the air outlet resistance of the first air outlet 110.

[0134] Optionally, the above step of adjusting the rotation angle of the second air guide plate 121 includes:

[0135] The controller adjusts the rotation angle of the second air guide plate 121 to be greater than or equal to 60°.

[0136] In this embodiment, when the second air guide plate 121 is at an angle greater than or equal to 60°, it has a better synergistic effect on the first air outlet 110, which helps to quickly reduce the air outlet resistance of the first air outlet 110. Further optionally, the rotation angle of the second air guide plate 121 is less than or equal to 120°, which can prevent the second air outlet 120 from opening too large, causing the air outlet resistance of the first air outlet 110 to be less than the air inlet resistance.

[0137] This disclosure also provides an apparatus for controlling an air conditioner, including a processor and a memory storing program instructions, the processor being configured to execute the above-described method for controlling the air conditioner when running the program instructions.

[0138] This disclosure also provides an air conditioner, including the above-described device for controlling the air conditioner.

[0139] In this embodiment, the noise-reducing louver assembly 200, the noise-reducing break assembly 300, the air intake regulating assembly 400, and their corresponding control methods can be combined to effectively solve the noise problem of the air conditioner.

[0140] In some embodiments, an air inlet 130, a cross-flow fan 140, a heat exchanger 500, and air outlets (a first air outlet 110 and a second air outlet 120) are sequentially arranged along the air supply duct inside the housing 100. The air inlet 130 is equipped with an air inlet regulating component 400 to match the air inlet resistance with the air outlet resistance; the intelligent matching control method is detailed above. This solves the noise problem caused by the mismatch between the air inlet and outlet resistances. A noise-reducing louver component 200 is provided between the cross-flow fan 140 and the heat exchanger 500 to discharge eddies upstream of the heat exchanger 500. A noise-reducing cut-off component 300 is provided between the heat exchanger 500 and the air outlet to discharge eddies downstream of the heat exchanger 500. Here, since there are many reasons for eddies to occur upstream of heat exchanger 500, such as volute pressure exceeding the preset volute pressure, volute airflow exceeding the preset volute airflow, and heat exchanger 500 blockage, using a controllable opening and closing noise-reducing louver assembly 200 upstream of heat exchanger 500 is beneficial for handling complex operating conditions. Because the pressure change at the air outlet is direct and significant when adjusting the air guide plate, using a noise-reducing break assembly 300 downstream of heat exchanger 500 that automatically opens and closes according to duct pressure is beneficial for rapid response to changes in duct pressure. This solves the noise problem caused by eddies upstream and downstream of heat exchanger 500. Therefore, the interaction of multiple structures effectively solves the noise problem of the air conditioner.
