[0020] 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.

[0021] 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.

[0022] Hereinafter, an air conditioner 100 according to an embodiment of the present invention will be described with reference to the accompanying drawings.

[0023] like Figure 1 As shown, the air conditioner 100 according to an embodiment of the present invention includes: an air conditioner body 1 and a protective grille 2. The air conditioner body 1 has an air outlet duct 11, which includes a first air outlet section 11a and a second air outlet section 11b. Airflow flows along the first air outlet section 11a and the second air outlet section 11b, and the air conditioner 100 delivers air. Figure 1The dotted line with arrows is used to indicate the direction of airflow. The outlets of the first air outlet section 11a and the second air outlet section 11b extend in different directions, thereby increasing the air supply range of the air conditioner 100 and improving the air supply effect.

[0024] The air outlet duct 11 is connected to the fan wheel of the air conditioner 100. The fan wheel provides airflow to the air outlet duct 11. The protective grille 2 is installed inside the air outlet duct 11 to prevent users from accidentally touching the fan wheel of the air conditioner 100. As a protective component, the protective grille 2 is non-removably installed inside the air outlet duct 11 to prevent users from accidentally touching internal components of the air conditioner 100, such as the working fan wheel, thus ensuring safety during use.

[0025] The protective grille 2 also includes a first diverter plate 21, which extends along the direction from the inlet 113 of the air outlet duct toward the first air outlet section 11a, and the outlet end 21b in the extension direction protrudes from any of the other grille bars 20 on the protective grille 2 to guide the airflow toward the first air outlet section 11a.

[0026] By setting the first diverter 21 to guide the airflow toward the first air outlet section 11a, the airflow of the first air outlet section 11a is increased. Optionally, the airflow at the outlet of the first air outlet section 11a can be increased to achieve better airflow performance for the air conditioner 100. For example, if the outlet of the first air outlet section 11a is located at the top of the air conditioner 100, the airflow at the top is increased when the air conditioner 100 is cooling, and the cold airflow naturally settles, improving user comfort; or if the outlet of the first air outlet section 11a is located on the side of the air conditioner 100, and the outlet direction extends along the wall, the airflow is delivered along the wall to a farther distance, increasing the air delivery distance, thereby improving the air delivery and heat exchange efficiency of the air conditioner 100.

[0027] Alternatively, by setting the first diverter plate 21 to guide airflow to the first air outlet section 11a, the airflow of the first air outlet section 11a can be increased, allowing the airflow to flow evenly to the first air outlet section 11a and the second air outlet section 11b. This ensures that the airflow volume at the outlets of the first air outlet section 11a and the second air outlet section 11b, located at different positions on the air conditioner 100, is similar, thereby improving the airflow performance of the air conditioner 100. It is understood that the airflow volume of the first and second air outlet sections may be uneven due to their positions, etc. By setting the first diverter plate 21 to guide airflow to the first air outlet section 11a, which originally has a lower airflow volume, the airflow volume of the first air outlet section 11a can be increased, thus balancing the airflow volume at the outlets of the first air outlet section 11a and the second air outlet section 11b.

[0028] This invention integrates the first diverter plate 21 directly with the protective grille 2. The protective grille 2 not only provides protection but also serves as a support and positioning element. The first diverter plate 21 does not need to be separately installed with the air conditioner body 1. Furthermore, since the first diverter plate 21 is part of the protective grille 2, it does not need to be installed separately with the protective grille 2. This saves on mounting and positioning components for the first diverter plate 21, reduces the structural complexity of the air conditioner 100, and improves the assembly efficiency of the air conditioner 100. The first diverter plate 21 and the protective grille 2 have good overall integrity, which also improves the structural strength of the first diverter plate 21 and ensures high operational stability.

[0029] According to an embodiment of the present invention, the air conditioner 100 integrates the first diverter plate 21 and the protective grille 2, eliminating the need for separate positioning and installation of the first diverter plate 21. This saves components, reduces the structural complexity of the air conditioner 100, and improves the assembly efficiency of the air conditioner 100. Furthermore, the good integrity of the first diverter plate 21 and the protective grille 2 enhances the structural strength of the first diverter plate 21 and strengthens its operational stability.

[0030] In some embodiments of the present invention, the length direction of the air outlet duct 11 is consistent with the length direction of the air conditioner 100. Therefore, the length direction of the first air outlet section 11a and the length direction of the second air outlet section 11b are also the length direction of the air conditioner 100. The air outlet area in the length direction of the air conditioner 100 is relatively large. The outlets of the first air outlet section 11a and the second air outlet section 11b extend towards both sides of the width of the air conditioner 100, respectively, to further increase the air outlet coverage area in the width direction of the air conditioner 100 and improve the air supply effect of the air conditioner 100. For example Figure 15 The vertical direction shown is the length direction of the air conditioner 100, and the horizontal direction is the width direction of the air conditioner 100.

[0031] In some embodiments, such as Figure 2 and Figure 3 As shown, the length direction of the air conditioner 100 is vertical, the air outlet duct 11 extends vertically, and the outlets of the first air outlet section 11a and the second air outlet section 11b extend towards the horizontal sides respectively, thereby increasing the air supply range of the air conditioner 100 in both the vertical and horizontal directions.

[0032] like Figure 2 and Figure 3As shown, the protective grille 2 includes multiple longitudinal bars 22. The length direction of the longitudinal bars 22 is consistent with the length direction of the air conditioner 100. The bars 22 can prevent users from accidentally touching the internal components of the air conditioner 100 for protection. One of the longitudinal bars 22 is constructed as a first diverter plate 21. By designing one of the longitudinal bars 22, which originally served a protective function, as a first diverter plate 21, the first diverter plate 21 can not only serve a protective function together with the other bars 20, but also serve a diversion function, thereby further simplifying the structure and reducing the manufacturing cost of the air conditioner 100.

[0033] The width of the first diverter plate 21 is divided into an inlet end 21a and an outlet end 21b, as follows: Figure 1 As shown, in the projection along the length of the first diverter plate 21, the end of the first diverter plate 21 near the inlet 113 of the air outlet duct is the inlet end 21a, and the end of the first diverter plate 21 near the outlet of the first air outlet section 11a is the outlet end 21b. The first diverter plate 21 guides the airflow to flow in the direction of the first air outlet section 11a.

[0034] In some embodiments of the present invention, such as Figure 4 As shown, at least one longitudinal bar 22 is configured as a first guide plate 221. The first guide plate 221 is located on the side of the first diverter plate 21 away from the second air outlet section 11b. The width direction of the first guide plate 221 extends along the direction from the inlet 113 of the air outlet duct toward the first air outlet section 11a.

[0035] The first deflector 221 also guides the airflow towards the first air outlet section 11a, thereby further increasing the airflow of the first air outlet section 11a and enabling the air conditioner 100 to achieve better airflow performance. By constructing the longitudinal grille 22 as the first deflector 221, the longitudinal grille 22, which originally served a protective function, is designed as the first deflector 221. The first deflector 221 can not only serve a protective function together with other grilles 20, but also serve a guiding function to reduce the wind resistance of the protective grille 2 to the airflow in the air outlet duct 11, and can guide the airflow, thereby improving the airflow fluidity.

[0036] In some embodiments of the present invention, such as Figure 1 As shown, the air conditioner body 1 also has an air inlet duct 12, the outlet of the air inlet duct 12 is connected to the inlet 113 of the air outlet duct, and the air inlet duct 12 provides airflow to the air outlet duct 11.

[0037] like Figure 1As shown, the outlet direction of the air inlet duct 12 and the outlet direction of the first air outlet section 11a are respectively oriented towards both sides of the width of the air conditioner 100. That is, the direction of airflow from the air inlet duct 12 into the air outlet duct 11 is inconsistent with the outlet direction of the first air outlet section 11a, making it difficult for the airflow to flow towards the first air outlet section 11a, resulting in a small airflow rate within the first air outlet section 11a. Therefore, the present invention sets up a first diverter plate 21 and a first guide plate 221 to guide the airflow towards the first air outlet section 11a, which can increase the airflow rate of the first air outlet section 11a, making the air supply volume at the outlet of the first air outlet section 11a and the outlet of the second air outlet section 11b balanced. This ensures that the air supply volume at the outlet of the first air outlet section 11a and the outlet of the second air outlet section 11b at different locations on the air conditioner 100 is similar, thereby improving the air supply effect of the air conditioner 100.

[0038] like Figure 4 As shown, there are multiple first guide vanes 221, which are spaced apart along the width direction of the first air outlet section 11a. By setting multiple first guide vanes 221, the airflow guiding effect to the first air outlet section 11a is further improved, and the airflow of the first air outlet section 11a is increased.

[0039] In some embodiments of the present invention, such as Figure 1 As shown, the air conditioner body 1 also includes a cross-flow fan 15, which is disposed in the air inlet duct 12 to provide airflow to the air outlet duct 11. Due to the air outlet shape of the cross-flow fan 15, the air inlet duct 12 has a volute, so the air outlet direction of the air inlet duct 12 is offset to one side, and the outlet direction of the air inlet duct 12 is towards the air outlet direction of the second air outlet section 11b, so that the airflow to the second air outlet section 11b is more than the airflow to the first air outlet section 11a. Therefore, this embodiment of the invention guides the airflow to the first air outlet section 11a by setting a first diverter plate 21 and multiple first guide plates 221, so as to balance the airflow of the first air outlet section 11a and the second air outlet section 11b, thereby improving the air supply effect of the air conditioner 100.

[0040] In some embodiments of the present invention, such as Figure 4 As shown, at least one longitudinal bar 22 is configured as a second guide plate 222. The second guide plate 222 is located on the side of the first diverter plate 21 away from the first air outlet section 11a. The width direction of the second guide plate 222 extends along the direction from the inlet 113 of the air outlet duct toward the second air outlet section 11b. The second guide plate 222 guides the airflow to flow toward the second air outlet section 11b.

[0041] By constructing the longitudinal grid strip 22 as a second guide plate 222, the longitudinal grid strip 22, which originally served a protective function, is designed as a second guide plate 222. The second guide plate 222 can not only serve a protective function together with the other grid strips 20, but also guide the airflow to reduce the wind resistance of the protective grid 2 to the airflow in the air outlet duct 11, and can guide the airflow to improve the airflow.

[0042] In some specific embodiments of the present invention, such as Figure 4 As shown, the protective grille 2 includes four longitudinal bars 22. The two longitudinal bars 22 closest to the first air outlet section 11a are configured as first guide plates 221, the one longitudinal bar 22 closest to the second air outlet section 11b is configured as a second guide plate 222, and the longitudinal bar 22 located between the first guide plate 221 and the second guide plate 222 is configured as a first diverter plate 21. Since the outlet direction of the air inlet duct 12 faces the air outlet direction of the second air outlet section 11b, the airflow flowing to the second air outlet section 11b is greater than the airflow flowing to the first air outlet section 11a. Therefore, in this embodiment of the invention, three of the four longitudinal bars 22 guide the airflow towards the first air outlet section 11a, so as to balance the airflow of the first air outlet section 11a and the second air outlet section 11b.

[0043] In some embodiments of the present invention, such as Figure 3 As shown, the protective grille 2 also includes multiple horizontal bars 23, which are spaced apart along the length of the air conditioner 100. The horizontal bars 23 intersect with the vertical bars 22 to define the grille openings. The grille openings defined by the protective grille 2 are smaller than the size of a user's palm to prevent the user from accidentally touching components inside the air conditioner 100, such as the working cross-flow fan 15, thus ensuring safety during use.

[0044] like Figure 3 and Figure 4 As shown, the lateral spacing W1 between two adjacent vertical gratings 22 is smaller than the longitudinal spacing H between adjacent horizontal gratings 23. The lateral distance W2 from the vertical grating 22 closest to the wall of the air duct to the wall of the air duct is smaller than the longitudinal spacing H between adjacent horizontal gratings 23. The length direction of the vertical gratings 22 is consistent with the length direction of the air outlet duct 11, while the horizontal gratings 23 are spaced apart along the length direction of the air conditioner 100. Therefore, the longitudinal spacing between the horizontal gratings 23 is designed to be larger to reduce the air resistance in the air outlet duct 11 and improve the airflow.

[0045] In some embodiments, the longitudinal spacing H between adjacent horizontal bars 23 is less than 400mm. When the longitudinal spacing H between adjacent horizontal bars 23 is too large, the area of ​​the grille holes increases, weakening the protective effect of the protective grille 2 and reducing its safety. Therefore, a longitudinal spacing H between adjacent horizontal bars 23 of less than 400mm is optimal. It is worth noting that the longitudinal spacing H between adjacent horizontal bars 23 should also not be too small. When the longitudinal spacing H between adjacent horizontal bars 23 is too small, the horizontal bars 23 are arranged too densely, encroaching on the space of the air outlet duct 11, increasing the air resistance within the air outlet duct 11, and affecting the air volume of the air conditioner 100. Optionally, the longitudinal spacing H between adjacent horizontal bars 23 can be 200mm, 220mm, 300mm, 350mm, 380mm, etc.

[0046] In some embodiments, the lateral spacing W1 between two adjacent longitudinal bars 22 is less than or equal to 20 mm. The longitudinal bars 22 form a guide channel to direct airflow; therefore, a lateral spacing W1 less than 20 mm is optimal for better airflow guidance. It is worth noting that one of the longitudinal bars 22 is a first diverter plate 21; therefore, the lateral spacing between the first diverter plate 21 and the adjacent longitudinal bar 22 is also W1. Optionally, the lateral spacing W1 between two adjacent longitudinal bars 22 can be 8 mm, 10 mm, 12 mm, 15 mm, 20 mm, etc.

[0047] In some embodiments, the lateral distance W2 from the longitudinal grid strip 22 closest to the wall of the air duct to the wall of the air duct is less than or equal to 20 mm. A guide channel is also formed between the longitudinal grid strip 22 and the wall of the air duct to guide the airflow. Therefore, a lateral distance W2 of less than or equal to 20 mm is optimal for better airflow guidance. Optionally, the lateral distance W2 from the longitudinal grid strip 22 closest to the wall of the air duct to the wall of the air duct is 5 mm, 6 mm, 10 mm, 18 mm, 20 mm, etc.

[0048] In some embodiments of the present invention, such as Figure 4 As shown, the air conditioner body 1 includes a first air duct wall 111 and a second air duct wall 112. An inlet section of the air outlet duct is formed between the first air duct wall 111 and the second air duct wall 112. The first air duct wall 111 participates in defining the first air outlet section 11a, and the second air duct wall 112 participates in defining the second air outlet section 11b.

[0049] like Figure 4As shown, the inlet end 21a of the first diverter plate is positioned close to the second duct wall 112 relative to the first duct wall 11. That is, the distance L1 between the first diverter plate 21 and the first duct wall 111 is greater than the distance L2 between the first diverter plate 21 and the second duct wall 112. This is beneficial for diverting more airflow to the first outlet section 11a and improving the air supply effect of the air conditioner 100.

[0050] In some embodiments of the present invention, such as Figures 5-7 As shown, the air conditioner body 1 includes a front frame 13 and an air outlet frame 14. The front frame 13 and the air outlet frame 14 together define a first air outlet section 11a and a second air outlet section 11b. A protective grille 2 is disposed on the air outlet frame 14. Figure 1 As shown, the cross-flow fan 15 includes a volute 151 and a cross-flow impeller 152 that cooperates with the volute 151. The volute 151 defines an inlet air duct 12 and is connected to an outlet frame 14 to deliver flowing air to a first outlet section 11a and a second outlet section 11b.

[0051] In Embodiment 1 of the present invention, as Figures 1-7 As shown, only a protective grille 2 is provided in the air outlet duct 11 for airflow guidance, which can reduce the structural complexity of the air conditioner 100 and improve the assembly efficiency of the air conditioner 100.

[0052] In Embodiment 2 of the present invention, as Figures 8-14 As shown, the air outlet duct 11 is equipped with a protective grille 2 and a diversion component 3 to divert airflow, which can further guide the airflow and improve the air outlet effect of the air conditioner 100.

[0053] In some embodiments of the present invention, such as Figure 8 and Figure 11 As shown, the air conditioner 100 also includes a flow divider 3, which is disposed within the air outlet duct 11. The flow divider 3 and the protective grille 2 can be two separately manufactured components, thereby reducing the manufacturing difficulty of the protective grille 2, improving the production efficiency of the air conditioner 100, and reducing the structural complexity of the protective grille 2, facilitating its storage and transportation. However, the installation location of the protective grille 2 is not limited; it can be installed on the flow divider 3 or on other components. But the invention is not limited to this; for example, in other embodiments of the invention, the flow divider 3 and the protective grille 2 can be manufactured as a single integral part.

[0054] like Figure 8 and Figure 10As shown, the flow diversion component 3 includes a second flow diversion plate 31, which extends along the direction from the inlet 113 of the air outlet duct toward the second air outlet section 11b. The outlet end 31b in the extending direction protrudes from any of the other bars 20 on the protective grille 2, except for the first flow diversion plate 21, to guide the airflow toward the second air outlet section 11b. Figure 8 The dashed line with an arrow is used to indicate the direction of airflow.

[0055] The first diverter plate 21 guides the airflow toward the first air outlet section 11a, and the second diverter plate 31 guides the airflow toward the second air outlet section 11b, so that the air volume of the first air outlet section 11a and the second air outlet section 11b is relatively uniform, so that the air conditioner 100 can uniformly discharge air to different directions in the room and improve the air outlet heat exchange effect of the air conditioner 100.

[0056] In other embodiments of the present invention, the second diverter plate 31, which guides the airflow toward the second air outlet section 11b, is integrally formed with the protective grille 2. The second diverter plate 31 does not require additional installation, thus saving on mounting and positioning components and improving the assembly efficiency of the air conditioner 100. Furthermore, the good integrity of the second diverter plate 31 and the protective grille 2 enhances the structural strength and operational reliability of the second diverter plate 31.

[0057] In some embodiments of the present invention, such as Figure 9 As shown, the length direction of the air outlet duct 11 is consistent with the length direction of the air conditioner 100. The outlet of the first air outlet section 11a and the outlet of the second air outlet section 11b extend toward the width sides of the air conditioner 100, respectively. The length direction of the second diverter plate 31 is consistent with the length direction of the air conditioner 100, so as to guide the airflow in the air outlet duct 11.

[0058] like Figure 9 As shown, the inlet end 31a of the second diverter plate extends towards the inlet end 21a of the first diverter plate, and the outlet end 31b of the second diverter plate extends towards both sides of the width of the air conditioner 100, just like the outlet end 21b of the first diverter plate. The inlet end 31a of the second diverter plate is farther from the inlet 113 of the air outlet duct than the inlet end 21a of the first diverter plate, which can increase the airflow to the first air outlet section 11a and improve the uniformity of airflow between the first air outlet section 11a and the second air outlet section 11b.

[0059] In some embodiments of the present invention, such as Figure 9As shown, the minimum flow width L3 of the first air outlet section 11a and the minimum flow width L4 of the second air outlet section 11b are equal. The flow effect of the airflow from the first air outlet section 11a to the outlet and from the second air outlet section 11b to the outlet is balanced. The arrangement of the first diverter plate 21 and the second diverter plate 31 no longer needs to consider the flow of airflow in the duct with different flow widths, which facilitates the design and arrangement of the first diverter plate 21 and the second diverter plate 31, reduces the assembly difficulty, and improves production efficiency.

[0060] In some embodiments of the present invention, such as Figure 8 and Figure 9 As shown, the inlet end 21a of the first diverter plate and the inlet end 31a of the second diverter plate are spaced apart. While achieving diversion and improving the uniformity of airflow distribution, this also ensures the flowability of airflow, improves the airflow efficiency, guarantees ventilation volume, and reduces airflow attenuation loss.

[0061] In some embodiments of the present invention, such as Figure 9 As shown, the air conditioner body 1 includes a first air duct wall 111 and a second air duct wall 112. The first air duct wall 111 defines a first air outlet section 11a, and the second air duct wall 112 defines a second air outlet section 11b. A first diverter plate 21 is disposed adjacent to the first air duct wall 111, and a second diverter plate 31 is disposed adjacent to the second air duct wall 112. The distance L5 between the inlet end 31a of the second diverter plate and the second air duct wall 112 is smaller than the distance L6 between the outlet end 31b of the second diverter plate and the second air duct wall 112. The second air outlet section 11b is defined as a flared flow channel by the second diverter plate 31 in the air outlet direction of the second air outlet section 11b, allowing the airflow to flow smoothly along the second air outlet section 11b.

[0062] In Embodiment 2 of the present invention, as Figure 11 and Figure 12 As shown, the diversion component 3 is disposed on the face frame 13, and the protective grille 2 is disposed on the air outlet frame 14. The face frame 13 and the air outlet frame 14 together define the first air outlet section 11a and the second air outlet section 11b. After the face frame 13 and the air outlet frame 14 are connected to each other, the diversion component 3 located on the face frame 13 and the protective grille 2 located on the air outlet frame 14 cooperate with each other in the air outlet duct 11 to guide the airflow to the second air outlet section 11b and the first air outlet section 11a respectively.

[0063] In Embodiment 2 of the present invention, as Figure 13 and Figure 14 As shown, the diversion component 3 also includes a mounting part 32, which is connected to the face frame 13 for positioning. The diversion component 3 is also provided with a plurality of mounting holes 37, through which fasteners pass to fix the diversion component 3 to the face frame 13, wherein at least one mounting hole 37 is provided on the mounting part 32.

[0064] like Figure 13and Figure 14 As shown, the flow distribution component 3 also includes a first reinforcing rib 34 connected to the second flow distribution plate 31 at a certain angle. The length direction of the first reinforcing rib 34 is consistent with the length direction of the air conditioner 100 to improve the structural strength of the second flow distribution plate 31, thereby improving the working stability of the second flow distribution plate 31. The flow distribution component 3 also includes a second reinforcing rib 35 connected between the first reinforcing rib 34 and the second flow distribution plate 31. There are multiple second reinforcing ribs 35, which are spaced apart along the length direction of the air conditioner 100. By setting the second reinforcing ribs 35, the structural strength of the flow distribution component 3 is further improved, and the working reliability of the second flow distribution plate 31 is improved.

[0065] In Embodiment 2 of the present invention, as Figure 13 and Figure 14 As shown, the second diverter plate 31 is also provided with avoidance grooves 33 to avoid the horizontal grille 23. Multiple avoidance grooves 33 are spaced apart along the length of the air conditioner 100 to avoid interference between the diverter component 3 and the protective grille 2, thereby improving the working stability of the protective grille 2 and the diverter component 3. Multiple third reinforcing ribs 36 are also provided on the second diverter plate 31. Avoidance grooves 33 are defined between two adjacent third reinforcing ribs 36. The third reinforcing ribs 36 are connected between the second diverter plate 31 and the first reinforcing rib 34, further improving the structural stability of the diverter component 3.

[0066] In some embodiments of the present invention, such as Figure 15 As shown, the air conditioner 100 includes a first air outlet 101 and a second air outlet 102 disposed on both sides in the width direction. The outlet of the first air outlet section 11a is connected to the first air outlet 101, and the outlet of the second air outlet section 11b is connected to the second air outlet 102. The air conditioner 100 also includes a third air outlet 103, which is disposed higher than the first air outlet 101 and the second air outlet 102, thereby increasing the air supply range of the air conditioner 100 in the vertical direction and improving the air supply effect of the air conditioner 100.

[0067] In some embodiments, such as Figure 16 As shown, the air conditioner body 1 also includes a top cover 17 and a chassis 18. The top cover 17 is located on the top of the air conditioner 100, and the chassis 18 is located at the bottom of the air conditioner 100. A third air outlet 103 is disposed on the top cover 17 to improve the air supply range of the air conditioner 100 in the vertical direction. The air conditioner body 1 also includes a rear cover 16, which is connected to the front frame 13. A cross-flow fan 15 is disposed inside the rear cover 16.
