[0048] The following describes in detail embodiments of the present invention. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0049] Reference below Figures 1-12 An air conditioner according to an embodiment of the present invention is described, wherein the direction indicated by the arrow in the figure is the direction of air flow.

[0050] refer to Figures 1-12 According to an embodiment of the present invention, the air conditioner includes: a casing 1 and a heat exchange and air supply component 2 and an air outlet frame component 3 arranged in the casing 1, and the heat exchange and air supply component 2 is located on the upstream side of the air outlet frame component 3.

[0051] The casing 1 has an air inlet 11 and an air outlet 12. The air outlet 12 is formed at the front of the casing 1. The air outlet 12 extends in the up and down directions, and the air outlet 12 includes a first air outlet 121, a second air outlet 122 and a third air outlet 123 arranged at intervals in the left and right directions. The third air outlet 123 is located on the front side of the casing 1, and the first air outlet 121 and the second air outlet 122 are located on the left and right sides of the third air outlet 123.

[0052] The heat exchange and air supply assembly 2 comprises a heat exchanger assembly 21 and an air duct assembly 22. The air duct assembly 22 includes an air duct volute and a rotor assembly. For example, the heat exchanger assembly 21 includes an evaporator assembly. Driven by the rotor assembly, indoor air enters the housing 1 through the air inlet 11 and exchanges heat with the heat exchanger assembly 21 to achieve cooling or heating regulation. The air then enters the room through the air outlet 12 to regulate the indoor temperature.

[0053] The air outlet frame assembly 3 is located on the front side of the heat exchange and air supply assembly 2. The air outlet frame assembly 3 includes an air outlet frame 31 and a control assembly 32 arranged on the air outlet frame 31. The air outlet frame 31 is fixed relative to the casing 1, and the air outlet frame 31 has an air outlet channel and an air flow inlet connected to the air outlet channel. Under the driving action of the wind wheel component, the air flow flows from the heat exchanger assembly 21 toward the air outlet frame assembly 3 and enters the air outlet channel through the air flow inlet.

[0054] The air outlet channel includes a main air outlet channel 4 and three outlet air channels 5 arranged at intervals along the left and right directions. The main air outlet channel 4 is located on the upstream side of the outlet air channel 5, and the main air outlet channel 4 is connected to each outlet air channel 5. The three outlet air channels 5 are respectively the first outlet air channel 51, the second outlet air channel 52 and the third outlet air channel 53.

[0055] Among them, the first outlet air channel 51 is opposite to and connected to the first air outlet 121, the second outlet air channel 52 is opposite to and connected to the second air outlet 122, and the third outlet air channel 53 is opposite to and connected to the third air outlet 123. The control component 32 is used to control the connection and isolation between the main air outlet channel 4 and the first outlet air channel 51, the connection and isolation between the main air outlet channel 4 and the second outlet air channel 52, and the connection and isolation between the main air outlet channel 4 and the third outlet air channel 53. When the control component 32 controls the connection and isolation between the main air outlet channel 4 and different outlet air channels 5 among the first outlet air channel 51, the second outlet air channel 52, and the third outlet air channel 53, the airflow in the outlet channel of the air outlet frame 31 has multiple possible flow paths and can flow out of the casing 1 into the room through the air outlets 12 corresponding to different outlet air channels 5, so that the air conditioner has more abundant air outlet modes. In this way, the user can adjust the air outlet mode of the air conditioner through the control component 32 according to the use requirements to improve the user experience.

[0056] For example, the control component 32 can simultaneously control the connection and isolation between the main air outlet channel 4 and the first air outlet channel 51, the connection and isolation between the main air outlet channel 4 and the second air outlet channel 52, and the connection and isolation between the main air outlet channel 4 and the third air outlet channel 53.

[0057] Optionally, the control assembly 32 includes a drive assembly and a baffle assembly, and the drive assembly is used to drive the baffle assembly to move relative to the air outlet frame 31. For example, the drive assembly includes a third motor.

[0058] Optionally, the baffle assembly has a first position and a second position, and the baffle assembly can be moved relative to the air outlet frame 31 to switch between the first position and the second position. In the first position, the main air outlet channel 4 is connected to the first and second air outlet channels 51, 52, and is separated from the third air outlet channel 53. The airflow in the housing 1 enters the room through the first and second air outlets 121, 122. In the second position, the main air outlet channel 4 is separated from the first and second air outlet channels 51, 52, and is connected to the third air outlet 123. The airflow in the housing 1 enters the room through the third air outlet 123.

[0059] Optionally, the baffle assembly may also have a third position, which is an intermediate position between the first position and the second position. In the third position, the main air outlet channel 4 is connected to the first air outlet channel 51, the second air outlet channel 52 and the third air outlet channel 53, so that the air flow in the casing 1 can enter the room at the same time through the first air outlet 121, the second air outlet 122 and the third air outlet 123.

[0060] For example, during the operation of the air conditioner, if the user needs the air conditioner to blow air into the room through the third air outlet 123 located on the front side of the casing 1, the control component 32 can be used to control the main air outlet channel 4 to be isolated from the first outlet air duct and the second outlet air duct 52, and to control the main air outlet channel 4 to be connected to the third outlet air duct 53, so that the air flows into the room through the third outlet air duct 53 and the third air outlet 123. At this time, the air flow path during the operation of the air conditioner is as follows: driven by the wind wheel component, the air flows into the casing 1 through the air inlet 11, first flows through the heat exchanger component 21 and exchanges heat with it, then flows through the air duct component 22 and enters the air outlet channel under the driving action of the wind wheel component, and the air flows through the main air outlet channel 4 and then flows through the third outlet air duct 53 in the air outlet channel, and finally enters the room through the third air outlet 123 to adjust the indoor temperature for cooling or heating.

[0061] For example, during the operation of the air conditioner, the user needs the air conditioner to blow air into the room through the first air outlet 121 and the second air outlet 122 located on the left and right sides of the casing 1. The control component 32 can be used to control the main air outlet channel 4 to be connected with the first outlet air duct and the second outlet air duct 52, and to control the main air outlet channel 4 to be separated from the third outlet air channel 53. The airflow is divided into two parts, one part of which enters the room through the first outlet air channel 51 and the first air outlet 121, and the other part enters the room through the second outlet air channel 52 and the second air outlet 122. At this time, the air flow path during the operation of the air conditioner is: under the driving action of the wind wheel component, the air flow enters the casing 1 through the air inlet 11, first flows through the heat exchanger assembly 21 and exchanges heat with it, and then flows through the air duct assembly 22 and enters the air outlet channel under the driving action of the wind wheel component. The air flow first flows through the main air outlet channel 4 in the air outlet channel and then flows through the first outlet air channel 51 and the third outlet air channel 53 respectively. Finally, the air flow in the first outlet air channel 51 enters the room through the first air outlet 121 to cool or heat the indoor temperature, and the air flow in the second outlet air channel 52 enters the room through the third air outlet 123 to cool or heat the indoor temperature.

[0062] According to the air conditioner of the embodiment of the present invention, by setting a control component 32 on the air outlet frame 31, the control component 32 can control the connection and isolation between the main air outlet channel 4 and the first air outlet channel 51, the connection and isolation between the main air outlet channel 4 and the second air outlet channel 52, and the connection and isolation between the main air outlet channel 4 and the third air outlet channel 53. In this way, during the operation of the air conditioner, the user can adjust the connection and isolation between the main air outlet channel 4 and the first air outlet channel 51, the second air outlet channel 52 and the third air outlet channel 53 through the control component 32 according to the usage requirements, so that the airflow flowing through the main air outlet channel 4 can flow toward the air outlet 12 through different air outlet channels 5 according to the user's adjustment, so that these airflows can flow out through different air outlets 12 such as the first air outlet 121, the second air outlet 122 and the third air outlet 123, so that the air conditioner has richer air outlet modes, which is conducive to the air conditioner to flexibly adjust the air outlet mode according to the user's usage requirements.

[0063] refer to Figures 1-6 According to some embodiments of the present invention, the air outlet frame 31 includes a left frame 311, a right frame 313 and a middle frame 312. The left frame 311 and the right frame 313 are located on the left and right sides of the middle frame 312. The middle frame 312 defines a third air outlet channel 53. The middle frame 312 and the left frame 311 jointly define the first air outlet channel 51. The middle frame 312 and the right frame 313 jointly define the second air outlet channel 52. The middle frame 312 guides the airflow in the third outlet air channel 53, and the middle frame 312 and the left frame 311 jointly guide the airflow in the first outlet air channel 51. The middle frame 312 and the right frame 313 jointly guide the airflow in the second outlet air channel 52, so that the airflow in the outlet channel can flow smoothly toward the air outlet 12, and the structure of the left frame 311, the right frame 313 and the middle frame 312 is used to define three outlet air channels 5, which can prevent the airflow in the outlet duct from escaping everywhere, which is beneficial to improving the air conditioning effect of the air conditioner.

[0064] Optionally, the left frame 311 , the middle frame 312 and the right frame 313 are connected to each other.

[0065] refer to Figures 1-6 According to some embodiments of the present invention, the third air outlet channel 53 includes a first air outlet section 531 that extends to the third air outlet 123. The extension direction of the first air outlet section 531 is parallel to the front-to-back direction. By aligning the extension direction of the first air outlet section 531 with the front-to-back direction, airflow within the first air outlet section 531 flows in the front-to-back direction under the guidance of the intermediate frame 312 and toward the third air outlet 123. Air then flows out of the housing 1 through the third air outlet 123 and into the interior of the room.

[0066] refer to Figures 1-6 According to some optional embodiments of the present invention, the flow area of ​​the first air outlet section 531 is the same from back to front. By making the flow area of ​​the first air outlet section 531 the same from back to front, the airflow within the housing 1 achieves a more uniform velocity and pressure distribution as it passes through the first air outlet section 531, avoiding airflow instability caused by changes in flow area. This helps provide smoother and more uniform air flow, thereby achieving a more uniform temperature distribution within the room. In addition, this configuration reduces turbulence and friction within the first air outlet section 531, thereby reducing noise caused by the airflow.

[0067] refer to Figures 1-6 According to some optional embodiments of the present invention, the third air outlet channel 53 includes a second air outlet section 532, the second air outlet section 532 is connected to the upstream side of the first air outlet section 531, the first air outlet section 531 connects the second air outlet section 532 and the third air outlet 123, and the flow area of ​​the second air outlet section 532 gradually increases from the back to the front, and the flow area of ​​the second air outlet section 532 is smaller than the flow area of ​​the first air outlet section 531.

[0068] Among them, the flow area of ​​at least part of the second air outlet section 532 is smaller than the flow area of ​​the first air outlet section 531, including the following situations: for example, the flow area of ​​part of the second air outlet section 532 is smaller than the flow area of ​​the first air outlet section 531; for another example, the overall flow area of ​​the second air outlet section 532 is smaller than the flow area of ​​the first air outlet section 531. By gradually increasing the flow area of ​​the second air outlet section 532 in the direction from back to front, the air flow in the second air outlet section 532 can reduce air flow losses during the process of flowing from back to front, thereby increasing the air output of the air conditioner and improving its air conditioning effect. The gradually expanding flow area can better disperse the air flow, make the air flow more evenly distributed, and avoid local overcooling or overheating. By making at least part of the flow area of ​​the second air outlet section 532 smaller than the flow area of ​​the first air outlet section 531, when the air flow enters the first air outlet section 531 from the second air outlet section 532, since the extension direction of the first air outlet section 531 is parallel to the front-to-back direction, after the air flow gradually expands through the second air outlet section 532, the air flow is guided forward by the first air outlet section 531 to be delivered toward the front of the entire machine.

[0069] refer to Figures 1-6According to some optional embodiments of the present invention, the first air outlet section 531 has a first interface 533 and a second interface 534 disposed opposite each other in the left-right direction. Both the first and second interfaces 533, 534 extend in the front-to-back direction. The second air outlet section 532 has a third interface 535 and a fourth interface 536 disposed opposite each other in the left-to-right direction. Both the third and fourth interfaces 535, 536 extend obliquely in the front-to-back direction. When air flows through the second air outlet section 532, it is guided by the obliquely extending third and fourth interfaces 535, 536. When air flows through the first air outlet section 531, it flows along the first and second interfaces 533, 534, which extend in the front-to-back direction, and is blown out to the front of the entire device.

[0070] refer to Figures 1-6 According to some embodiments of the present invention, the width of the first outlet air channel 51 is the same as the width of the second outlet air channel 52. By making the width of the first outlet air channel 51 and the width of the second outlet air channel 52 the same, the amount of air passing through these two channels is roughly the same, thereby achieving more uniform airflow distribution. This helps improve indoor temperature uniformity, avoids excessive or insufficient airflow in certain areas, and thus improves user comfort. Furthermore, the same width simplifies the design and manufacturing process of the air outlet frame 31, reduces the need for molds and tools of different specifications, and reduces production costs.

[0071] refer to Figure 1-Figure 3 According to some embodiments of the present invention, the width of the first air outlet channel 51 is A, and the width of the second air outlet channel 52 is B, and the value range of A and B is 40mm to 60mm. Optionally, the values ​​of A and B can be: 40mm, 42mm, 45mm, 48mm, 50mm, 55mm, 60mm, etc. If the value range of A and B is less than 40mm, the air flow in the first air outlet channel 51 and the second air outlet channel will be small, so that the air flow entering the room through the air outlet channel will also be reduced accordingly, which will have an adverse effect on the regulation effect of the air conditioner; if the value range of A and B is greater than 60mm, the structural dimensions of the air outlet frame 31 in the left and right directions will increase accordingly, so that the entire structural dimensions of the air conditioner in the left and right directions need to be increased accordingly, which is not conducive to the miniaturization of the air conditioner. By setting the value range of A and B to 40 mm to 60 mm, the flow rate of the airflow in the first outlet air channel 51 and the second outlet air channel 52 is more appropriate, so that the air conditioner can have a good air conditioning effect, and the structural size of the air conditioner is also more appropriate.

[0072] refer to Figure 1-Figure 3According to some embodiments of the present invention, the width of the first air outlet channel 51 is A, and the width of the second air outlet channel 52 is B. The value range of A or B is 40mm to 60mm. Optionally, the value of A can be: 40mm, 42mm, 45mm, 48mm, 50mm, 55mm, 60mm, etc. The value of B can be: 40mm, 42mm, 45mm, 48mm, 50mm, 55mm, 60mm, etc.

[0073] If the value range of A or B is less than 40 mm, the airflow through the first outlet air channel 51 and the second outlet air channel will be small, resulting in a corresponding decrease in the amount of air entering the room through the outlet channel, which will adversely affect the air conditioning effect of the air conditioner. If the value range of A or B is greater than 60 mm, the structural dimensions of the air outlet frame 31 in the left-right direction will increase accordingly, which will also require a corresponding increase in the overall structural dimensions of the air conditioner in the left-right direction, which is not conducive to the miniaturization of the air conditioner. By setting the value range of A or B to 40 mm to 60 mm, the airflow through the first outlet air channel 51 and the second outlet air channel 52 is more appropriate, so that the air conditioner can achieve good air conditioning effect, and the structural dimensions of the air conditioner are also more appropriate.
