[0047] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein 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 with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0048] The following disclosure provides numerous different embodiments or examples for implementing various structures of the invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. Additionally, examples of various specific processes and materials are provided in this invention; however, those skilled in the art will recognize the applicability of other processes and / or the use of other materials.

[0049] An indoor air conditioning unit 100 according to an embodiment of the present invention will now be described with reference to the accompanying drawings.

[0050] like Figure 1 and Figure 5 As shown, the indoor unit 100 of the air conditioner according to an embodiment of the present invention includes: a housing 10, a door opening and closing assembly 5, a heat exchanger 21, and a fan 22.

[0051] Specifically, such as Figure 2 and Figure 5 As shown, a first air inlet channel 11 is defined inside the housing 10. The housing 10 has a top air inlet 131 that communicates with the first air inlet channel 11. An air outlet channel 15 is defined inside the housing 10 and communicates with the first air inlet channel 11. The housing 10 has a first air outlet 141 that communicates with the air outlet channel 15. A heat exchanger 21 and a fan 22 are disposed inside the first air inlet channel 11. The top air inlet 131 is partially opposite to the heat exchanger 21.

[0052] It is understandable that the heat exchanger 21 and the fan 22 are located in the first air inlet channel 11. The fan 22 is used to drive the airflow through the top air inlet 131 into the first air inlet channel 11 and exchange heat with the heat exchanger 21 before blowing it out to the room from the first air outlet 141, thereby regulating the indoor ambient temperature.

[0053] For example, in one embodiment of the present invention, a rotatable inner air guide plate 8 is provided inside the air outlet airflow channel 15. Thus, by providing the inner air guide plate 8 inside the air outlet airflow channel 15, the direction of airflow can be changed and adjusted by rotating the inner air guide plate 8.

[0054] Optionally, a rotatable louver can be installed in the air outlet channel 15. The louver can guide the airflow to the left and right. The louver can be located upstream of the airflow direction of the inner air guide plate 8.

[0055] like Figure 3 and Figure 5 As shown, the door opening and closing assembly 5 is movably disposed on the housing 10 between a first position and a second position. The door opening and closing assembly 5 includes a movable panel, which includes a first connecting portion 51 (see reference 51) that is connected vertically. Figure 10 The first connecting part 51 has a side air inlet 133, and the second connecting part 52 has a plurality of air diffusers 521. The first connecting part 51 is located above the second connecting part 52. When the door assembly 5 is in the first position, the door assembly 5 opens the first air outlet 141, and the air diffusers 521 are connected to the first air inlet channel 11. The air diffusers 521 are partially opposite to the heat exchanger 21. When the door assembly 5 is in the second position, the door assembly 5 closes the first air outlet 141, and the side air inlet 133 is connected to the first air inlet channel 11. The side air inlet 133 is partially opposite to the heat exchanger 21.

[0056] It is understandable that when the door opening and closing assembly 5 is in the second position, the airflow can enter the first airflow channel through the top air inlet 131 and the side air inlet 133 respectively to exchange heat with the heat exchanger 21; when the door opening and closing assembly 5 is in the first position, the airflow can enter the first airflow channel through the top air inlet 131 and the diffuser 521 respectively to exchange heat with the heat exchanger 21. Thus, heat exchange with the heat exchanger 21 can be achieved in two directions and two positions, thereby improving the heat exchange efficiency of the heat exchanger 21, increasing the cooling and heating capacity of the heat exchanger 21, and thus improving the working efficiency of the air conditioning indoor unit 100.

[0057] Furthermore, when the door opening and closing assembly 5 is in the second position, the air conditioner indoor unit 100 can discharge air through the first air outlet 141 and disperse the airflow through multiple air diffusers 521 on the second connecting part 52, making the airflow gentle and achieving a windless airflow mode. At this time, the air conditioner indoor unit 100 can be in cooling mode, reducing or avoiding the discomfort caused by cold air blowing directly on the human body, while ensuring a large air volume to guarantee the cooling capacity in the windless mode.

[0058] For example, in one embodiment of the invention, the door opening / closing assembly 5 is movable up and down between a first position and a second position to open or close the first air outlet 141.

[0059] In some embodiments of the present invention, such as Figure 4 and Figure 5As shown, the housing 10 includes: a chassis, a front frame 1 and a panel 7. The front frame 1 is connected to the chassis. The front frame 1 has a top air inlet 131 and a first air outlet 141. The front frame 1 and the chassis define a first air inlet channel 11. The door opening and closing assembly 5 is movably mounted on the front frame 1 between a first position and a second position.

[0060] In some embodiments of the present invention, such as Figure 2 and Figure 3 As shown, multiple air diffusers 521 are distributed in multiple rows and columns. This improves the smoothness and uniformity of airflow through the second connection 52, resulting in higher heat exchange efficiency between the airflow and the heat exchanger 21. Simultaneously, it reduces airflow resistance, thereby reducing the dynamic loss of airflow.

[0061] In some embodiments of the present invention, the cross-section of the air diffuser 521 is formed as a circle, an ellipse, or a polygon. Therefore, the shape of the cross-section of the air diffuser 521 can be selected according to the model, size, and application environment of the air conditioner indoor unit 100, thereby improving the versatility of the air conditioner indoor unit 100 and better meeting user needs. Of course, the present invention is not limited to this; the cross-section of the air diffuser 521 can also be oblong, such as racetrack-shaped.

[0062] According to an embodiment of the present invention, the air conditioner indoor unit 100 is provided with a side air inlet 133 on the door opening assembly 5. When the door opening assembly 5 is in the second position, the airflow can enter the first airflow channel through the top air inlet 131 and the side air inlet 133 respectively to exchange heat with the heat exchanger 21. When the door opening assembly 5 is in the first position, the airflow can enter the first airflow channel through the top air inlet 131 and the air diffuser 521 respectively to exchange heat with the heat exchanger 21. Thus, heat exchange with the heat exchanger 21 can be achieved in two directions, thereby improving the heat exchange efficiency of the heat exchanger 21, increasing the cooling and heating capacity of the heat exchanger 21, and thus improving the working efficiency of the air conditioner indoor unit 100.

[0063] According to some embodiments of the present invention, such as Figure 5 and Figure 6 As shown, the indoor unit 100 of the air conditioner also includes a first partition 3, which is located at the side air inlet 133 to block the side air inlet 133. The first partition 3 has multiple air inlet holes 31. It can be understood that indoor airflow can enter the first air inlet airflow channel 11 through the air inlet holes 31. In addition, by setting the first partition 3, the first partition 3 can block larger particles from the outside of the indoor unit 100 of the air conditioner, thereby improving the reliability of the operation of the indoor unit 100.

[0064] In some embodiments of the present invention, such as Figure 6 and Figure 10As shown, multiple air inlets 31 are distributed in multiple rows and columns. This improves the smoothness and uniformity of airflow through the first baffle 3, resulting in higher heat exchange efficiency between the airflow and the heat exchanger 21. Simultaneously, it reduces airflow resistance, thereby reducing the dynamic loss of airflow.

[0065] In some embodiments of the present invention, the cross-section of the air inlet 31 is formed as a circle, ellipse, or polygon. Therefore, the shape of the cross-section of the air inlet 31 can be selected according to the model, size, and application environment of the air conditioner indoor unit 100, thereby improving the versatility of the air conditioner indoor unit 100 and better meeting user needs. Of course, the present invention is not limited to this; the cross-section of the air inlet 31 can also be oblong, such as racetrack-shaped.

[0066] In some embodiments of the present invention, the first partition 3 and the first connecting part 51 are integrally formed. Therefore, the integral structure not only ensures the structural and performance stability of the first partition 3 and the first connecting part 51, but also facilitates molding and simplifies manufacturing. Furthermore, it eliminates unnecessary assembly parts and connection processes, greatly improving the assembly efficiency of the first partition 3 and the first connecting part 51 and ensuring the connection reliability of the first partition 3 and the first connecting part 51. Moreover, the integrally formed structure has higher overall strength and stability, is more convenient to assemble, and has a longer service life.

[0067] According to some embodiments of the present invention, such as Figure 5 and Figure 6 As shown, the housing 10 also defines a second air intake channel 12. The second air intake channel 12 is located in front of the first air intake channel 11. The upper end of the second air intake channel 12 is connected to the top air inlet 131. The lower end of the second air intake channel 12 is provided with a front air inlet 132 connected to the first air intake channel 11. In the first position, the air diffuser 521 is connected to the second air intake channel 12. In the second position, the side air inlet 133 is connected to the second air intake channel.

[0068] Understandably, the airflow entering the housing 10 from the top air inlet 131 can be diverted into the first air inlet channel 11 and the second air inlet channel 12. The airflow diverted into the second air inlet channel 12 can flow along the second air inlet channel 12 and merge back into the first air inlet channel 11 through the front air inlet 132 at the lower end of the second air inlet channel 12. Thus, the single airflow at the inlet position can be dispersed into two streams, which then merge into the first air inlet channel 11 through the two different top air inlets 131 and front air inlets 132.

[0069] Specifically, when the door opening and closing assembly 5 is in the second position, the airflow that exchanges heat with the heat exchanger 21 includes three streams: one stream enters the first air intake airflow channel 11 directly through the top air inlet; another stream enters the second air intake airflow channel 12 through the top air inlet 131 and then enters the first air intake airflow channel 11 through the front air inlet 132; and the third stream enters the second air intake airflow channel 12 through the side air inlet 133 and then enters the first air intake airflow channel 11 through the front air inlet 132.

[0070] When the door opening and closing assembly 5 is in the first position, the airflow that exchanges heat with the heat exchanger 21 includes three streams: one stream enters the first air intake channel 11 directly through the top air inlet; another stream enters the second air intake channel 12 through the top air inlet 131 and then enters the first air intake channel 11 through the front air inlet 132; and the third stream enters the second air intake channel 12 through the air diffuser 521 and then enters the first air intake channel 11 through the front air inlet 132.

[0071] In some embodiments of the present invention, such as Figure 5 and Figure 6 As shown, in the first position, the air diffuser 521 (refer to...) Figure 3 In a second position, opposite to the front air inlet 132, the side air inlet 133 is opposite to the front air inlet 132. This shortens the airflow path from the diffuser 521 to the front air inlet 132 and prevents changes in airflow direction during the process, thus improving the smoothness of airflow entering the front air inlet 132 from the diffuser 521. Similarly, it shortens the airflow path from the side air inlet 133 to the front air inlet 132 and prevents changes in airflow direction during the process, further improving the smoothness of airflow entering the front air inlet 132 from the side air inlet 133.

[0072] In some embodiments of the present invention, such as Figure 5 and Figure 7 As shown, the indoor unit 100 of the air conditioner also includes a second partition 4, which is located at the air inlet 132 to block the air inlet 132. The second partition 4 has multiple ventilation holes 41. It can be understood that indoor airflow can enter the first air inlet channel 11 through the ventilation holes 41. Furthermore, by providing the second partition 4, larger particles can be blocked from entering the outside of the first air inlet channel 11, thereby improving the reliability of the indoor unit 100.

[0073] In some embodiments of the present invention, such as Figure 8 and Figure 9As shown, multiple ventilation holes 41 are distributed in multiple rows and columns. This improves the smoothness and uniformity of airflow through the second baffle 4, resulting in higher heat exchange efficiency between the airflow and the heat exchanger 21. Simultaneously, it reduces airflow resistance, thereby reducing the dynamic loss of airflow.

[0074] In some embodiments of the present invention, the cross-section of the ventilation hole 41 is formed as a circle, ellipse, or polygon. Therefore, the shape of the cross-section of the ventilation hole 41 can be selected according to the model, size, and application environment of the air conditioner indoor unit 100, thereby improving the versatility of the air conditioner indoor unit 100 and better meeting user needs. Of course, the present invention is not limited to this; the cross-section of the ventilation hole 41 can also be oblong, such as racetrack-shaped.

[0075] In some embodiments of the present invention, such as Figure 5 and Figure 6 As shown, the portion of the heat exchanger 21 opposite to the second partition 4 matches the outer contour of the second partition 4. This increases the heat exchange area between the airflow and the heat exchanger 21, thereby further improving heat exchange efficiency and the operating efficiency of the indoor air conditioning unit 100. Furthermore, the overall structure of the indoor air conditioning unit 100 is more compact, resulting in a more uniform gap between the second partition 4 and the heat exchanger 21, reducing airflow noise.

[0076] In some embodiments of the present invention, the second partition 4 and the housing 10 are integrally formed. Therefore, the integral structure not only ensures the structural and performance stability of the second partition 4 and the housing 10, but also facilitates molding and simplifies manufacturing. Furthermore, it eliminates unnecessary assembly parts and connection processes, greatly improving the assembly efficiency of the second partition 4 and the housing 10, and ensuring the reliability of their connection. Moreover, the integrally formed structure has higher overall strength and stability, is easier to assemble, and has a longer service life. For example, in one example of the present invention, the second partition 4 and the face frame 1 are integrally formed.

[0077] In one example of the present invention, such as Figure 2 and Figure 4 As shown, face frame 1 (refer to) Figure 5 The upper end of the door assembly 5 is provided with a panel 7 and the panel 7 is located on the front side of the face frame 1. A receiving cavity is defined between the panel 7 and the face frame 1. When the door assembly 5 is in the first position, the first connecting part 51 is located in the receiving cavity.

[0078] Therefore, when the door opening and closing assembly 5 moves upward to the second position, the first connecting part 51 moves upward and enters and is stored in the receiving cavity through the bottom of the receiving cavity, facilitating the storage and concealment of the first connecting part 51; when the door opening and closing assembly 5 moves downward to the first position, the first connecting part 51 moves downward to the outside of the receiving cavity and is located below the receiving cavity. During the movement of the door opening and closing assembly 5, the receiving cavity also serves as a guide, making the up-and-down movement of the door opening and closing assembly 5 more stable and reliable. Furthermore, it also makes the appearance of the air conditioner indoor unit 100 more aesthetically pleasing.

[0079] For example, in one example of the present invention, such as Figure 5 and Figure 6 As shown, the second partition 4 includes a first partition portion 42 extending vertically and a second partition portion 43 extending horizontally. The second partition portion 43 is located at the top of the first partition portion 42 and is connected to the face frame 1. The second partition portion 43 is located at the bottom of the receiving cavity, and the front end face of the second partition portion 43 defines a receiving channel between itself and the panel 7, allowing the first connecting portion 51 to pass through. It is understood that defining a receiving channel between the front end face of the second partition portion 43 and the panel 7 facilitates the vertical movement of the door assembly 5, thereby facilitating the vertical movement of the first connecting portion 51 to be stored or removed from the receiving cavity. The size of the receiving channel is slightly larger than the thickness of the first connecting portion 51.

[0080] It should be noted that ventilation holes 41 are provided on both the first partition part 42 and the second partition part 43.

[0081] Specifically, refer to Figure 5 The outer contours of the first partition 42 and the corresponding part of the heat exchanger 21 are matched. As a result, the overall structure of the air conditioner indoor unit 100 is compact, and the gap between the first partition 42 and the heat exchanger 21 is relatively uniform, reducing airflow noise.

[0082] According to some embodiments of the present invention, such as Figure 10 and Figure 11 As shown, the door opening and closing assembly 5 includes a diffuser module 6 with a diffuser function. The diffuser module 6 is disposed on the second connecting part 52. The diffuser module 6 includes a mounting plate 61 and a diffuser mechanism. The mounting plate 61 has a plurality of first air outlet holes 611 arranged in the left-right direction. The diffuser mechanism is disposed at the first air outlet holes 611. The diffuser mechanism includes a guide vane assembly 62. Each first air outlet hole 611 is provided with a guide vane assembly 62. The guide vane assembly 62 includes a stationary vane 621 and a rotatable moving vane 622. The stationary vane 621 and the moving vane 622 are arranged along the axial direction of the first air outlet hole 611. Along the airflow direction, the moving vane 622 is disposed downstream or upstream of the stationary vane 621. The moving vane 622 and the stationary vane 621 are coaxially arranged.

[0083] Therefore, when the door opening and closing assembly 5 is in the second position, the air blown out from the first air outlet 141 can be swirled and diffused by the diffuser module 6, making the airflow more dispersed and giving the airflow a certain swirling direction, further enhancing the windless effect.

[0084] For example, in one example of this application, the moving blade 622 is located downstream of the stationary blade 621. When the airflow passes through the diffuser module 6, the airflow passes through the guiding, rectifying and dispersing effects of the stationary blade 621 in sequence, and then flows through the moving blade 622. The moving blade 622 can have a certain swirl direction, so that the airflow has a certain swirl direction after passing through the moving blade 622. Finally, the airflow is further dispersed through the diffuser hole 521 on the second connecting part 52, making the airflow softer and closer to natural wind.

[0085] The relative position of the blades of the moving blade 622 and the stationary blade 621 can be changed by controlling the rotation of the moving blade 622, thereby adjusting the ventilation area of ​​the first air outlet 611 and thus adjusting the air volume and air velocity. When the indoor unit 100 of the air conditioner is working and the door opening / closing assembly 5 is in the second position, the moving blade 622 can be controlled to rotate to a certain angle and then stop rotating, or the moving blade 622 can be controlled to rotate continuously.

[0086] According to some embodiments of the present invention, such as Figure 1 and Figure 4 As shown, at least one of the left and right sides of the housing 10 is provided with an airflow channel 15 (connected to the housing). Figure 5 The second air outlet 142 is connected. In other words, the second air outlet 142 is provided on the left side of the housing 10; or, the second air outlet 142 is provided on the right side of the housing 10; or, a second air outlet 142 is provided on both the left and right sides of the housing 10. As a result, air can be discharged from more angles and over a wider range, increasing the air volume and improving efficiency.

[0087] For example, a second air outlet 142 is formed on the left side of the frame 1, so that when the air conditioner indoor unit 100 discharges air, it can discharge air in the forward, downward and left directions to form 3D air outlet; a second air outlet 142 is formed on the right side of the frame 1, so that when the air conditioner indoor unit 100 discharges air, it can discharge air in the forward, downward and right directions to form 3D air outlet; a second air outlet 142 is formed on both the left and right sides of the frame 1, so that when the air conditioner indoor unit 100 discharges air, it can discharge air in the forward, downward, left and right directions to form 4D air outlet.

[0088] Specifically, when the door opening and closing assembly 5 is in the second position, the indoor unit 100 of the air conditioner is in the windless mode. Since at least one second air outlet 142 is added on the left and right sides, the air outlets on the left and right sides will not blow directly onto the human body. While ensuring the windless mode is achieved, the cooling capacity in the windless mode can be further increased.

[0089] For example, in Figure 4 and Figure 5 In the example, a second air outlet 142 is formed on both the left and right ends of the face frame 1. End plates are provided on both the left and right sides of the face frame 1. The end plates can be in the shape of a grille. The air outlet 142 can discharge air from the gaps in the end plates. Thus, when the indoor unit 100 is in the windless mode, the air outlets on the left and right sides can be gentler, improving the overall windless effect of the indoor unit 100.

[0090] In one example of the present invention, reference is made to Figure 10 and Figure 11 The drive mechanism 9 for driving the door opening and closing assembly 5 to move up and down includes a motor 91, a gear, and a rack 92. The motor 91 is mounted on the chassis of the indoor unit 100 of the air conditioner, and the chassis is connected to the front frame 1. The gear is connected to the output shaft of the motor 91. The rack 92 is mounted on the door opening and closing assembly 5 and extends in the vertical direction. The rack 92 is adapted to mesh with the gear. Thus, by driving the gear to rotate through the motor 91, the rack 92 is driven to move up and down, thereby driving the door opening and closing assembly 5 to move up and down.

[0091] Optionally, the rack 92 is mounted on the movable panel of the door opening / closing assembly 5, and the rack 92 is detachably connected to the movable panel, thereby facilitating the removal, installation, and replacement of the rack 92. Alternatively, the rack 92 and the movable panel are integrally formed. This simplifies the assembly process of the indoor air conditioning unit 100 and improves the connection strength between the rack 92 and the movable panel.

[0092] An air conditioner according to an embodiment of the present invention will now be described with reference to the accompanying drawings.

[0093] An air conditioner according to an embodiment of the present invention includes the above-described indoor unit 100.

[0094] According to an embodiment of the present invention, an air conditioner is provided with a side air inlet 133 on the door opening assembly 5. When the door opening assembly 5 is in the second position, the airflow can enter the first airflow channel through the top air inlet 131 and the side air inlet 133 respectively to exchange heat with the heat exchanger 21. When the door opening assembly 5 is in the first position, the airflow can enter the first airflow channel through the top air inlet 131 and the air diffuser 521 respectively to exchange heat with the heat exchanger 21. Thus, heat exchange with the heat exchanger 21 can be achieved in two directions, thereby improving the heat exchange efficiency of the heat exchanger 21, increasing the cooling and heating capacity of the heat exchanger 21, and thus improving the working efficiency of the indoor unit 100 of the air conditioner.
