[0054] The embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation to the present invention.

[0055] Below, refer to Figures 1 - 15 To describe the air outlet frame assembly according to the embodiments of the present invention.

[0056] Reference Figure 6 、 Figure 8 and Figure 15 According to the air outlet frame assembly of the first aspect embodiment of the present utility model, it includes a first air outlet frame 31 and a switch door mechanism 34. The first air outlet frame 31 forms a first air outlet passage 311, and the air outlet end of the first air outlet passage 311 is adapted to be opposite to and communicate with the air outlet 12 of the air conditioner. The air guide grille 33 is arranged in the first air outlet passage 311 and the air guide grille 33 is integrally formed with the first air outlet frame 31. The first air outlet passage 311 is opposite to and communicates with the air outlet 12 of the air conditioner, which can enable the air flow after heat exchange in the air conditioner to smoothly blow out through the first air outlet passage 311 and the air outlet 12.

[0057] The air guide grille 33 is arranged in the first air outlet passage 311, which can play a guiding role in the air flow in the first air outlet passage 311, enable the air flow to flow more smoothly towards the air outlet 12, reduce the loss during the air flow process, and is beneficial to improving the air output.

[0058] The integral formation of the air guide grille 33 and the first air outlet frame 31 can improve the overall structural strength of the air guide grille 33 and the first air outlet frame 31, and can eliminate the assembly process between the first air outlet frame 31 and the air guide grille 33, thereby improving the assembly efficiency of the air outlet frame assembly, and can also reduce the parts required for the assembly between the first air outlet frame 31 and the air guide grille 33, which is beneficial to cost reduction.

[0059] Moreover, the integral formation of the air guide grille 33 and the first air outlet frame 31 can eliminate or reduce the assembly gap between the air guide grille 33 and the first air outlet frame 31, thereby reducing the noise when the air flow passes through the assembly gap between the air guide grille 33 and the first air outlet frame 31, improving the user experience, and can also reduce the abnormal noise problems caused by the phenomenon of thermal expansion and contraction of the air guide grille 33 or the first air outlet frame 31, and can also reduce the abnormal noise generated by the collision between the air guide grille 33 and the first air outlet frame 31 due to the vibration during the operation of the air conditioner.

[0060] For example, if the air guide grille 33 and the first air outlet frame 31 are of a split structure, there is likely to be an assembly gap between the air guide grille 33 and the first air outlet frame 31 during their assembly. When the air conditioner operates in the heating mode, the temperature of the air flow passing through the air guide grille 33 and the first air outlet frame 31 may be too high, which easily causes the air guide grille 33 or the first air outlet frame 31 to expand thermally. The expansion degrees of the air guide grille 33 and the first air outlet frame 31 may vary, which may lead to a decrease in the assembly gap between the air guide grille 33 and the first air outlet frame 31 and cause the air guide grille 33 and the first air outlet frame 31 to be squeezed, thereby generating noise. By integrally forming the air guide grille 33 and the first air outlet frame 31, the assembly gap between the air guide grille 33 and the first air outlet frame 31 can be eliminated or reduced, effectively reducing the change in the assembly gap between the air guide grille 33 and the first air outlet frame 31 caused by the difference in expansion degrees, and further reducing the noise generated due to the change in the assembly gap.

[0061] For another example, if the air guide grille 33 and the first air outlet frame 31 are of a split structure, there is likely to be an assembly gap between the air guide grille 33 and the first air outlet frame 31 during their assembly. When the air conditioner operates in the cooling mode, the temperature of the air flow passing through the air guide grille 33 and the first air outlet frame 31 may be too low, which easily causes the air guide grille 33 or the first air outlet frame 31 to contract cold. The cold contraction degrees of the air guide grille 33 and the first air outlet frame 31 may vary, which may lead to an increase in the assembly gap between the air guide grille 33 and the first air outlet frame 31 and reduce the connection stability between the air guide grille 33 and the first air outlet frame 31. The air conditioner will vibrate during operation, and further cause abnormal noise at the connection between the air guide grille 33 and the first air outlet frame 31.

[0062] By integrally forming the air guide grille 33 and the first air outlet frame 31, the assembly gap between the air guide grille 33 and the first air outlet frame 31 can be eliminated or reduced, effectively reducing the change in the assembly gap between the air guide grille 33 and the first air outlet frame 31 caused by the difference in cold contraction degrees, and further reducing the noise generated due to the change in the assembly gap.

[0063] The door opening and closing mechanism 34 includes a door 341 and a first driving mechanism 342. The first driving mechanism 342 is disposed on the first air outlet frame 31 and the first driving mechanism 342 is connected to the door 341. The first driving mechanism 342 is used to drive the door 341 to move to open or close the air outlet 12. The door opening and closing mechanism 34 can control the opening or closing of the air outlet 12. By connecting the first driving structure to the door 341, the door 341 can be driven to open or close, thereby opening the air outlet 12 to allow the air flow to blow out from the air outlet 12, or closing the air outlet 12 to prevent external dust from entering the air conditioner through the air outlet 12.

[0064] According to the air outlet frame assembly of the embodiments of the present utility model, by arranging the air guide grille 33 in the first air outlet passage 311 and integrally forming the air guide grille 33 with the first air outlet frame 31, the overall structural strength of the first air outlet frame 31 and the air guide grille 33 can be improved, and the assembly process between the air guide grille 33 and the first air outlet frame 31 can be omitted to improve the assembly efficiency of the air outlet frame assembly; moreover, the integral formation of the air guide grille 33 and the first air outlet frame 31 can eliminate or reduce the assembly gap between the first air outlet frame 31 and the air guide grille 33, thereby reducing the noise when the air flow passes through the assembly gap between the first air outlet frame 31 and the air guide grille 33, reducing the abnormal noise problem caused by the thermal expansion and contraction phenomenon of the air guide grille 33 or the first air outlet frame 31, and reducing the abnormal noise generated at the connection between the air guide grille 33 and the first air outlet frame 31 due to the vibration during the operation of the air conditioner, improving the user experience.

[0065] Referring to Figures 9 - 11 , according to some embodiments of the present utility model, a first mounting seat 312 is provided on the first air outlet frame 31, the first driving mechanism 342 is installed on the first mounting seat 312, and the first mounting seat 312 is integrally formed with the first air outlet frame 31. The integral formation of the first mounting seat 312 and the first air outlet frame 31 can enhance the overall structural strength of the first mounting seat 312 and the first air outlet frame 31, omit the assembly process between the first mounting seat 312 and the first air outlet frame 31, thereby improving the assembly efficiency of the air conditioner, and reducing the possibility of abnormal noise generated at the connection between the first mounting seat 312 and the first air outlet frame 31 due to the vibration during the operation of the air conditioner; moreover, the parts required for the assembly of the first mounting seat 312 and the first air outlet frame 31 can be omitted, which is beneficial to cost reduction.

[0066] Referring to Figure 6 , Figure 8 and Figure 12 , according to some embodiments of the present utility model, the switch door 341 extends in the up and down direction, the first mounting seats 312 are arranged on the upper and lower sides of the first air outlet passage 311, and the two first driving mechanisms 342 connected to the switch door 341 are respectively installed on the two first mounting seats 312 located on the upper and lower sides. The lower surface of the first mounting seat 312 located on the upper side constitutes at least part of the top wall of the air outlet passage, and the upper surface of the first mounting seat 312 located on the lower side constitutes at least part of the bottom wall of the first air outlet passage 311.

[0067] The switch door 341 extends in the up and down direction, ensuring that when the switch door 341 is in the closed position, it can block the air outlet 12 to close the air outlet 12, reducing the possibility of air leakage through the air outlet 12 and preventing dust from entering the interior of the air conditioner through the air outlet 12. When the switch door 341 is in the open position, it can connect the air outlet 12 with the outside of the air conditioner to open the air outlet 12, ensuring that the air flow can smoothly flow out of the air conditioner from the air outlet 12.

[0068] The first mounting base 312 is provided on the upper and lower sides of the first air outlet passage 311, and the first driving mechanism 342 is installed on the first mounting base 312. The first mounting base 312 can facilitate the installation of the first driving mechanism 342 on the first air outlet frame 31, and can also stably support the first driving mechanism 342. Since the two first driving mechanisms 342 are respectively installed on the two first mounting bases 312 on the upper and lower sides, and the first driving mechanism 342 is connected to the switch door 341, the first driving mechanisms 342 on the upper and lower sides of the switch door 341 can balance the force state of the switch door 341, ensure the stability of the switch door 341 during movement, and reduce the possibility of the switch door 341 tilting or shifting.

[0069] The lower surface of the upper first mounting base 312 constitutes at least part of the top wall of the first air outlet passage 311, and the upper surface of the lower first mounting base 312 constitutes at least part of the bottom wall of the first air outlet passage 311. For example, the lower surface of the upper first mounting base 312 can be closely attached to the upper side of the switch door 341, and the upper surface of the lower first mounting base 312 can be closely attached to the lower side of the switch door 341. When the air outlet 12 is in the closed state, the switch door 341 is in the closed position, which can ensure the sealing effect at the switch door 341 and reduce the possibility of air leakage from the first air outlet passage 311 through the switch door 341; when the air outlet 12 is in the open state, the switch door 341 is in the open position, which can make the air flow from the first air outlet passage 311 to the air outlet 12 flow more smoothly, and reduce the blockage of the first air outlet passage 311 by the switch door 341 to reduce the resistance during air flow.

[0070] Among them, the lower surface of the upper first mounting base 312 constituting at least part of the top wall of the first air outlet passage 311 can include the following situations: for example, part of the top wall of the first air outlet passage 311 can be constituted by the lower surface of the upper first mounting base 312; for another example, the entire top wall of the first air outlet passage 311 can be constituted by the lower surface of the upper first mounting base 312.

[0071] The upper surface of the lower first mounting base 312 constituting at least part of the bottom wall of the first air outlet passage 311 can include the following situations: for example, part of the bottom wall of the first air outlet passage 311 can be constituted by the upper surface of the lower first mounting base 312; for another example, the entire bottom wall of the first air outlet passage 311 can be constituted by the upper surface of the lower first mounting base 312.

The receiving cavity 313 can facilitate the installation of the first driving mechanism 342 on the first air outlet frame 31 and can make the overall structure of the first driving mechanism 342 and the first air outlet frame 31 compact.

[0095] According to some embodiments, the switch door mechanism 34 includes a switch door 341 and a first driving mechanism 342. The first driving mechanism 342 is disposed on the first air outlet frame 31 and connected to the switch door 341. The first driving mechanism 342 is configured to drive the switch door 341 to move to open or close the air outlet 12. A plurality of first mounting seats 312 are provided on the air outlet frame. Two first mounting seats 312 are provided on the upper and lower sides of the first sub-air outlet channel 319, and two first mounting seats 312 are provided on the upper and lower sides of the second sub-air outlet channel 320.

The first louver 354 is located in the first sub-air outlet channel 319, the second louver 355 is located in the first sub-air outlet channel 319, and the connecting rod 351 is located between the first louver 354 and the second louver 355 and is integrally connected to the first louver 354 and the second louver 355.

[0099] Reference Figure 6 and Figure 7 According to some embodiments of the present utility model, the air guide grille 33 includes a plurality of air guide grille bars 331 arranged at intervals in the left-right direction. An air guide channel 332 is defined between adjacent air guide grille bars 331. The wall surface of the air guide grille bar 331 facing the air guide channel 332 constitutes a flow guiding surface 333. The flow guiding surface 333 can guide the air flow in the first sub-air outlet channel 319 and the second sub-air outlet channel 320, and can divert the air flow to the corresponding air outlet 12, thereby effectively increasing the air flow rate of the air outlet 12.

[0100] The flow guiding surface 333 of the air guide grille 33 on the left side extends obliquely leftward in the front-to-back direction, and the flow guiding surface 333 of the air guide grille 33 on the right side extends obliquely rightward in the front-to-back direction. This can make the air flow flow at a preset angle, ensure the guiding effect of the flow guiding surface 333 on the air flow in the first sub-air outlet channel 319 and the second sub-air outlet channel 320, divert the air flow to the corresponding left or right air outlet 12 respectively, reduce the loss of the air flow during the flowing process, and thus effectively increase the air flow rate of the left or right air outlet 12.

[0101] Reference Figure 7 According to some embodiments of the present utility model, the included angle α between the flow guiding surface 333 and the front-to-back direction ranges from 10° to 30°. For example, the included angle α between the flow guiding surface 333 and the front-to-back direction can be 10°, 15°, 20°, 25°, 30°, etc. By making the included angle between the flow guiding surface 333 and the front-to-back direction not less than 10°, it can be ensured that the direction of the air flow can be effectively changed, and further ensure that the air flow can flow out towards the left or right air outlet 12; by making the included angle α between the flow guiding surface 333 and the front-to-back direction not greater than 30°, while guiding the air flow to flow out towards the left or right air outlet 12, the noise generated by the air flow due to too large a rotation angle can be reduced, and the loss of the air flow is reduced. When the rotation angle of the air flow is too large, eddy currents and relatively large noise may be generated, reducing the flow efficiency of the air flow and increasing the resistance of the air flow, thereby increasing the loss of the air flow. By making the included angle α between the flow guiding surface 333 and the front-to-back direction not greater than 30°, the included angle between the flow guiding surface 333 and the front-to-back direction can be made more reasonable, so that the direction of the air flow can be effectively changed while reducing the generation of noise.

[0102] By making the included angle α between the flow guiding surface 333 and the front-to-back direction be 10° to 30°, it can be ensured that the direction of the air flow can be effectively changed, and the noise generated by the air flow due to too large a rotation angle can be reduced, and the loss of the air flow is reduced.

[0103] Reference Figure 7, according to some embodiments of the present utility model, the air guide grille 33 includes a plurality of air guide grille bars 331 spaced at intervals in the left-right direction, and the spacing w1 between adjacent air guide grille bars 331 is not greater than 10.5 mm. For example, the spacing w1 between adjacent air guide grille bars 331 can be 0.5 mm, 3 mm, 6.5 mm, 8 mm, 10.5 mm, etc. By setting the spacing w1 between adjacent air guide grille bars 331 to be not greater than 10.5 mm, the safety of using the air guide grille 33 can be ensured, and further the safety of using the air conditioner can be ensured. The relatively close air guide grille bars 331 can prevent foreign objects (such as the user's fingers) from entering the air outlet channel, ensuring the safety of use.

[0104] Refer to Figure 2 and Figure 13 , according to some embodiments of the present utility model, the air outlet frame assembly includes a second air outlet frame 38.

Both the first sub-air outlet channel 319 and the second sub-air outlet channel 320 communicate with the second air outlet channel 381. The second air outlet frame 38 being detachably connected to the upstream side of the first air outlet frame 31 allows for quick assembly or disassembly according to actual needs. When it is necessary to clean, maintain, or replace the first air outlet frame 31 or the second air outlet frame 38, it is convenient to disassemble the second air outlet frame 38 and the first air outlet frame 31, reducing the maintenance cost and disassembly time. A second air outlet channel 381 is formed in the second air outlet frame 38, and the second air outlet channel 381 is located upstream of the first air outlet channel 311, which can pre-adjust the air flow, helping to more precisely adjust the air flow distribution and reducing the air flow loss.

[0105] Refer to Figure 1 , Figure 2 and Figure 5 , for the air conditioner according to the second aspect embodiments of the present utility model, the air conditioner includes a housing 1, a heat exchange and air supply assembly, and the air outlet frame assembly according to the above first aspect embodiments. An air inlet 11 is formed at the rear of the housing 1, and an air outlet 12 is formed at the front of the housing 1. The heat exchange and air supply assembly is disposed inside the housing 1, and the air outlet frame assembly is disposed inside the housing 1 and the air outlet frame assembly is located on the front side of the heat exchange and air supply assembly. The heat exchange and air supply assembly may include a heat exchanger component and a fan component. The heat exchanger component may be located between the air inlet 11 and the fan component, and the air outlet frame assembly may be located between the air outlet 12 and the fan component. The heat exchange and air supply assembly is located between the air inlet 11 and the air outlet 12. When the air conditioner is operating, air flows into the housing 1 through the air inlet 11 and flows towards the heat exchange and air supply assembly. The air heated or cooled by the heat exchange and air supply assembly can be blown out through the air outlet 12 into the room to cool or heat the room.

[0106] Optionally, the air conditioner may have a draft-free mode. The switch door 341 is formed with air-diffusing holes penetrating the switch door 341 in the thickness direction of the switch door 341. When the air conditioner is in the draft-free mode, the switch door 341 is in the closed position. The air flow enters the housing 1 through the air inlet 11 and flows towards the heat exchange and air supply assembly. The air after heat exchange by the heat exchange and air supply assembly can be blown out through the air-diffusing holes on the switch door 341 to cool or heat the room. While meeting the required cooling / heating effect of the user, the draft feeling of the blown air flow can be effectively reduced, thereby enhancing the user experience.

[0107] Optionally, the housing 1 includes a rear case 7 and a panel assembly. The rear case 7 can be connected to the rear side of the panel assembly. The air inlet 11 is formed on the rear case 7, and the air outlet 12 is formed on the panel assembly. The number of the air outlets 12 is one or more. The fan component can be disposed inside the rear case 7, and the air outlet 12 is located in front of the fan component.

[0108] In some embodiments of the present utility model, an air guiding channel may be formed inside the panel assembly. The air guiding channel is communicated with the room. The air guiding channel and the second air outlet channel 381 can be communicated through a communication port. The first air outlet channel 311 and the second air outlet channel 381 are located inside the panel assembly, and the second air outlet channel 381 is located on the upstream side of the first air outlet channel 311. When the air conditioner is operating, the air guiding channel can introduce the indoor air into the second air outlet channel 381. The air introduced into the second air outlet channel 381 through the air guiding channel does not exchange heat with the heat exchanger component. The normal-temperature air introduced into the second air outlet channel 381 from the air guiding channel is mixed with the air flow after heat exchange and is blown out to the room through the first air outlet channel 311 and the air outlet 12.

[0109] The air outlet frame assembly may further include an air guiding mechanism 39. The air guiding mechanism 39 is disposed inside the air guiding channel. The air guiding mechanism 39 includes a valve 391 and a channel assembly 392. The valve 391 is used to control the opening or closing of the air guiding channel. An avoidance groove is formed inside the channel assembly 392. When the valve 391 opens the air guiding channel, at least a part of the valve 391 is received in the avoidance groove.

[0110] When both the air outlet 12 and the air guiding channel are in the open state and the air conditioner is in the cooling mode, a high-speed air flow flows out at the air outlet 12, and a local negative pressure area can be formed in the second air outlet channel 381. At this time, the air with a higher temperature in the external space of the panel assembly can be introduced into the second air outlet channel 381 through the air guiding channel, and is mixed with the air with a lower temperature in the second air outlet channel 381, and then flows towards the air outlet 12 through the first air outlet channel 311 and is blown out from the air outlet 12 to cool the room. By introducing the external air, the air outlet temperature of the air outlet 12 can be gradually reduced, avoiding the discomfort caused by the sudden change of the air outlet temperature.

[0111] When the air outlet 12 and the air guiding channel are both in the open state and the air conditioner is in the heating mode, high-speed flowing gas flows out of the air outlet 12, and a local negative pressure area can be formed in the second air outlet channel 381. The relatively cold air in the external space of the panel assembly can be introduced into the second air outlet channel 381 through the air guiding channel, and is mixed with the relatively hot air in the second air outlet channel 381, and then flows to the air outlet 12 through the first air outlet channel 311 and flows out of the air outlet 12 to raise the indoor temperature. By introducing external air, the air outlet temperature of the air outlet 12 can be gradually increased, avoiding discomfort caused by sudden changes in the air outlet temperature.

[0112] When the air outlet 12 is in the closed state and the air guiding channel is in the open state, a high-pressure area can be formed in the second air outlet channel 381. At this time, the air guiding channel can be used as an exhaust channel, so that at least a part of the air flow in the second air outlet channel 381 can be discharged to the outside of the air conditioner through the air guiding channel.

[0113] Wherein, the air guiding channel includes a first sub-air guiding channel 393 and a second sub-air guiding channel 394. The first sub-air guiding channel 393 and the second sub-air guiding channel 394 are respectively located on the left and right sides of the panel assembly. An air guiding mechanism 39 is provided in the air guiding channel. There are two air guiding mechanisms 39, which are respectively arranged in the first sub-air guiding channel 393 and the second sub-air guiding channel 394, and the two air guiding mechanisms 39 respectively control the opening or closing of the two air guiding channels.

[0114] In the air conditioner according to the embodiment of the present invention, by arranging the air guide grille 33 in the first air outlet channel 311 and integrally forming the air guide grille 33 with the first air outlet frame 31, the overall structural strength of the first air outlet frame 31 and the air guide grille 33 can be improved, and the assembly process between the air guide grille 33 and the first air outlet frame 31 can be omitted to improve the assembly efficiency of the air outlet frame assembly; moreover, the integral formation of the air guide grille 33 and the first air outlet frame 31 can eliminate or reduce the assembly gap between the first air outlet frame 31 and the air guide grille 33, thereby reducing the noise when the air flow passes through the assembly gap between the first air outlet frame 31 and the air guide grille 33, and also reducing the abnormal noise problem caused by the thermal expansion and contraction phenomenon of the air guide grille 33 or the first air outlet frame 31, and further reducing the abnormal noise generated at the connection between the air guide grille 33 and the first air outlet frame 31 due to the vibration of the air conditioner during operation, improving the user experience.
