Air conditioners can be categorized by installation method as vertical, wall-mounted, or ceiling-mounted. Vertical air conditioners are primarily used in large public spaces such as living rooms, schools, and hospitals. Traditional vertical air conditioner indoor units often perform poorly during transport, dropping and impacting. They have low overall rigidity and are prone to significant deformation, bending, and shaking. This is especially true where the bottom of the air duct connects to the inclined column, which is prone to bending and damage. The lower half of the duct is also prone to bending, which can affect the stability of the indoor unit. Summary of the Invention

[0027] This embodiment provides a vertical air conditioner indoor unit. By setting up triangular supports, the air duct plate can be made more stable through the stable triangular shape, effectively improving the stability of the air duct plate, and further improving the overall stability of the vertical air conditioner indoor unit, thereby preventing the vertical air conditioner indoor unit from bending and deforming during transportation and falling.

Figure 6 yes Figure 4 A magnified schematic diagram of area B in the middle. Figure 7 yes Figure 2 Schematic diagram of the structure of the central triangle support 210 and the horizontal column support 240.

[0028] like Figures 1 to 7 As shown, a vertical air conditioner indoor unit 100 generally includes a housing 110, an air duct plate 120, and a triangular support 210. The housing 110 defines a cavity 118 within the housing. The air duct plate 120 is disposed within the cavity 118 and configured as a duct assembly to define an air duct. The triangular support 210 is disposed within the cavity 118 and is fixedly connected to the air duct plate 120.

[0029] Furthermore, the triangular support 210 may include a first support portion 211 and a second support portion 212, with an angle formed between the first support portion 211 and the second support portion 212. The vertical air conditioner indoor unit 100 of this embodiment, by providing the triangular support 210, can further stabilize the air duct plate 120 through the stable triangular shape, effectively improving the stability of the air duct plate 120, thereby improving the overall stability of the vertical air conditioner indoor unit 100 and preventing the vertical air conditioner indoor unit 100 from bending or deforming during transportation or dropping.

[0030] In a specific embodiment, the housing 110 may include a front panel 111, and the front panel 111 may be provided with an air outlet 114. The air duct plate 120, as an air duct component, may define an air duct together with other air duct components (not shown). The air duct allows cold or hot air to flow toward the air outlet 114, and then be delivered to the environment of the vertical air conditioner indoor unit 100 through the air outlet 114.

[0031] In addition, the housing 110 may further include a rear panel (not shown in the figure), which may be provided with an air inlet for allowing air outside the vertical air conditioner indoor unit 100 to enter the internal cavity 118 of the housing 110. In a preferred embodiment, the air inlet may be provided in the form of an air inlet grille, which can draw air outside the vertical air conditioner indoor unit 100 into the cavity 118 from different directions and provide a certain coarse filtering effect. In addition, the housing 110 may further include: a top cover 117 and a base 116, wherein the top cover 117 can be provided on the top of the front panel 111, and the base 116 can be provided on the bottom of the front panel 111. The top cover 117 and the base 116 can effectively enhance the overall aesthetics of the vertical air conditioner indoor unit 100.

[0032] In a specific embodiment, the vertical air conditioner indoor unit 100 may further include a main body (not shown), disposed within the cavity 118 and configured to perform heat exchange with air entering the cavity 118 through the air inlet and to blow the heat-exchanged air out through the air outlet 114. The air inlet is configured to allow air from the indoor environment where the vertical air conditioner indoor unit 100 is located to enter the cavity 118. The main body performs heat exchange with and blows out the indoor environment air that has entered the cavity 118.

[0033] Generally, the main body may include: a heat exchanger and a fan. The heat exchanger is configured to exchange heat for the air entering the cavity 118 through the air inlet. The fan may be configured to blow the heat-exchanged air out through the air outlet 114. The shape of the heat exchanger may be matched with the air inlet so that all the air passing through the air inlet enters the heat exchanger for heat exchange, and the air heated by the heat exchanger is blown out through the air outlet 114 by the fan. The fan may be set to a variety of types according to actual conditions, such as a centrifugal fan, an axial flow fan, a cross-flow fan, etc. In a preferred embodiment, the fan is a cross-flow fan, which is also matched with the air outlet 114, which can effectively improve the air output volume and air output efficiency.

[0034] In addition, the vertical air conditioner indoor unit 100 may further include an air guide plate (not shown) configured to controllably open and close the air outlet 114. Generally, when the vertical air conditioner indoor unit 100 is in the shutdown state, the air guide plate closes the air outlet 114 to prevent pollutants in the indoor ambient air from entering the interior of the housing 110 through the air outlet 114. When the vertical air conditioner indoor unit 100 is in the startup state, the air guide plate opens the air outlet 114, allowing the processed air inside the vertical air conditioner indoor unit 100 to be delivered to the indoor space through the air outlet 114. The processed air refers to the indoor ambient air that enters the cavity 118, undergoes heat exchange in the heat exchanger, and is blown out by the fan.

[0035] In a preferred embodiment, a filter component may be provided at the air guide plate to ensure that the air delivered to the room through the air outlet 114 meets the user's health needs. Furthermore, the vertical air conditioner indoor unit 100 may further include a swing blade 115 provided at the air outlet 114 and connected to the air duct plate 120. When the cold or hot air transported by the air duct is delivered to the air outlet 114, the air outlet direction can be adjusted by adjusting the posture of the swing blade 115.

[0036] Current vertical air conditioner indoor units often perform poorly during transport drops and impacts, with low overall rigidity, prone to significant deformation, bending, and shaking. This is particularly true where the bottom of the air duct connects to the inclined column, which is prone to bending and damage. The lower half of the air duct is also prone to bending, thus affecting the stability of the vertical air conditioner indoor unit. The vertical air conditioner indoor unit 100 of this embodiment, by providing triangular supports 210, can further stabilize the air duct plate 120 through its stable triangular shape, effectively improving the stability of the air duct plate 120 and, in turn, the overall stability of the vertical air conditioner indoor unit 100, thereby preventing bending and deformation of the vertical air conditioner indoor unit 100 during transport drops.

[0037] like Figure 7 As shown, in a specific embodiment, the triangular support 210 may further include: a flat plate portion 213, a mounting portion 214, and a load-bearing portion 215. Furthermore, the flat plate portion 213 extends horizontally to the right from the front end of the first support portion 211; the mounting portion 214 extends obliquely rearward from the right end of the flat plate portion 213; the load-bearing portion 215 extends horizontally to the right from the rear end of the mounting portion 214; and the second support portion 212 extends obliquely rearward from the right end of the load-bearing portion 215.

[0038] In addition, the triangular support 210 may further include: a first connecting portion 216 and a second connecting portion 217. The first connecting portion 216 extends horizontally to the left from the rear end of the first support portion 211; the second connecting portion 217 extends horizontally to the right from the rear end of the second support portion 212. Figure 7 As shown, each part of the triangular support 210, such as the first connecting portion 216, the second connecting portion 217, the first supporting portion 211, the second supporting portion 212, the flat portion 213, the mounting portion 214, and the load-bearing portion 215, can be provided with flanges 218 at both ends. Furthermore, the flanges 218 are all oriented forward or diagonally forward. The provision of flanges 218 can improve the stability of each part of the triangular support 210, thereby improving the overall stability of the triangular support 210 and the stability of the air duct plate 120 fixedly connected thereto.

[0039] like Figure 1 and Figure 2As shown, the vertical air conditioner indoor unit 100 may further include: a left column support 220 and a right column support 230, and the housing 110 may include a left panel 112 and a right panel 113. Moreover, the left column support 220 is fixed to the left panel 112, and the right column support 230 is fixed to the right panel 113. Figures 2 to 7 As shown, the vertical air conditioner indoor unit 100 may further include a horizontal column support 240 having a third support portion 241, a third connection portion 242, and a fourth connection portion 243. Furthermore, the left end of the third support portion 241 extends rearward to form the third connection portion 242; the right end of the third support portion 241 extends rearward to form the fourth connection portion 243.

[0040] In a preferred embodiment, screw holes are defined between the third connecting portion 242 and the left upright support 220, allowing screws to secure the third connecting portion 242 to the left upright support 220. Screw holes are defined between the fourth connecting portion 243 and the right upright support 230, allowing screws to secure the fourth connecting portion 243 to the right upright support 230. The securing of the third connecting portion 242 to the left upright support 220 and the securing of the fourth connecting portion 243 to the right upright support 230 effectively secure the transverse upright support 240 to the left and right upright supports 220 and 230. Furthermore, because the left upright support 220 is secured to the left panel 112 and the right upright support 230 is secured to the right panel 113, the left and right upright supports 220 and 230 are effectively secured to the housing 110. Therefore, the transverse upright support 240 is indirectly secured to the housing 110.

[0041] like Figures 5 to 7 As shown, screw holes are provided at the left ends of the first connecting portion 216 and the third supporting portion 241, respectively, so that the first connecting portion 216 and the third supporting portion 241 can be fixed by screws. Screw holes are provided at the right ends of the second connecting portion 217 and the third supporting portion 241, respectively, so that the second connecting portion 217 and the third supporting portion 241 can be fixed by screws. The fixing of the first connecting portion 216 and the third supporting portion 241, and the fixing of the second connecting portion 217 and the third supporting portion 241, actually fixes the triangular support 210 and the horizontal column support 240. Because the horizontal column support 240 mentioned above is indirectly fixed to the housing 110, the triangular support 210 and the housing 110 are also indirectly fixed.

[0042] In a preferred embodiment, Figures 3 to 6 As shown, a reinforcing support 250 may be provided at the lower left side and rearward of the air duct plate 120. Furthermore, a grid rib 251 may be provided on the reinforcing support 250. The reinforcing support 250 and the grid rib 251 provided on the reinforcing support 250 can effectively prevent the air duct plate 120 from bending and optimize its force transmission path.

[0043] More preferably, screw holes are provided at the lower ends of the mounting portion 214 and the reinforcing support 250, allowing screws to secure the mounting portion 214 to the reinforcing support 250. The securing of the mounting portion 214 to the reinforcing support 250 effectively secures the triangular support 210 to the reinforcing support 250, and further secures the triangular support 210 to the air duct plate 120 on which the reinforcing support 250 resides. Furthermore, because the aforementioned triangular support 210 is indirectly secured to the housing 110, the lower end of the air duct plate 120 is also indirectly secured to the housing 110, effectively increasing the support rigidity of the lower end of the air duct plate 120 and, consequently, its stability.

[0044] like Figure 5 and Figure 6 As shown, a clearance groove 252 is provided on the outer side of the screw hole on the reinforcing support 250 to avoid the load-bearing portion 215. The provision of the clearance groove 252 can prevent the load-bearing portion 215 of the triangular support 210 from interfering with or colliding with the reinforcing support 250, and the structural design is scientific and reasonable. It should also be emphasized that the load-bearing portion 215 of the triangular support 210 can effectively support the load. The triangular shape of the triangular support 210 and the horizontal column support 240 is also more stable and will not collapse when subjected to force.

[0045] The corresponding screw holes on the mounting portion 214 and the lower end of the reinforcing support 250 allow installers to simply screw in from the side, creating a scientific and rational assembly method that effectively improves efficiency. Furthermore, within the limited installation space, without changing the existing structure within the cavity 118 of the housing 110, the scientifically and rationally structured support assembly optimizes the force transmission path of the air duct plate 120 and increases its overall rigidity.

[0046] like Figure 2 As shown, the vertical air conditioner indoor unit 100 may further include a rear column support 270, the upper end of which may be fixed to the middle partition 130 inside the cavity 118, and the lower end of which may be fixed to the base 116 of the housing 110. The middle partition 130 may be located above the horizontal column support 240 and the triangular support 210.

[0047] Figure 3 and Figure 4 What is actually shown is a schematic diagram of the structure between the air duct plate 120, the left column support 220, the right column support 230, the triangular support 210, and the horizontal column support 240. Figure 3 and Figure 4 As shown, the vertical air conditioner indoor unit 100 may further include: a front column support 260, the upper end of which is fixed to the bottom end of the air duct plate 120, and the lower end can be fixed to the base 116 of the shell 110, thereby indirectly fixing the bottom of the air duct plate 120 to the shell 110.

[0048] In fact, the upper end of the air duct plate 120 can also be fixed to the top cover 117 of the housing 110. In this way, the upper and lower ends of the air duct plate 120 of the vertical air conditioner indoor unit 100 of this embodiment are fixed to the housing 110. In particular, the lower half of the air duct plate 120 is also fixed to the housing 110 through the triangular support 210 and the horizontal column support 240, further improving the support rigidity of the lower half of the air duct plate 120. Figure 3 As shown, the front column support 260 has a certain degree of curvature. This is because a control box (not shown) may be located there. The curvature of the front column support 260 effectively avoids the control box, making the various components in the cavity 118 compact and reducing the occupied volume. The control box can be configured to control the operating state of the vertical air conditioner indoor unit 100, for example, the cooling / heating mode or the air supply mode of the vertical air conditioner indoor unit 100.

[0049] However, the curved structure of the front column support 260 also impedes the downward force transmission path of the air duct plate 120. The front column support 260 provides insufficient support rigidity for the air duct plate 120, often resulting in damage at its connection to the air duct plate 120 during transport drop tests. Therefore, the vertical air conditioner indoor unit 100 of this embodiment, while taking into account installation labor costs and available space, incorporates transverse column supports 240 and triangular supports 210 to secure the lower half of the air duct plate 120 to the housing 110, effectively improving the support rigidity of the lower half of the air duct plate 120.

[0050] In addition, the vertical air conditioner indoor unit 100 may also include: multiple accessories (not shown) disposed within the cavity 118. These multiple accessories refer to components other than those specifically mentioned above, but are all disposed within the cavity 118. The large number and variety of components disposed within the cavity 118 contributes to the difficulty of providing support for the duct plate 120. The vertical air conditioner indoor unit 100 of this embodiment addresses this technical challenge by establishing a rationally structured support assembly and employing a scientific assembly method.

[0051] The terms "upper," "lower," "left," "right," "front," and "rear" used in this embodiment to indicate positions or locations are based on the actual use of the floor-standing air conditioner indoor unit 100. In other embodiments, the above-mentioned terms indicating positions or locations may be reversed. In this case, the corresponding connection relationships between the triangular support 210, the left column support 220, the right column support 230, the transverse column support 240, the air duct plate 120, and the housing 110 may also be adaptively reversed, thereby achieving a structure symmetrical to that of this embodiment.

[0052] In a preferred embodiment, the vertical air conditioner indoor unit 100 may further include a fresh air system configured to allow outdoor air to enter the cavity 118, perform heat exchange on it, and then blow it out through the air outlet 114. In other words, the main unit processes the indoor air entering the cavity 118, while the fresh air system processes the outdoor air entering the cavity 118. The combination of the two can effectively solve the problem of indoor air pollution, improve the air supply quality of the air conditioner, efficiently purify the air delivered to the room, and enhance user comfort.

[0053] Specifically, fresh air systems provide fresh air indoors without opening windows. They also effectively remove mold and odors, expelling damp, polluted air from indoor spaces, eradicating odors and preventing mold and bacterial growth, thereby extending the lifespan of buildings and furniture. They also help reduce noise pollution, eliminating the need for the distractions of opening windows, resulting in quieter and more comfortable indoor spaces. While regulating room temperature, fresh air systems can also reduce energy consumption. Avoiding window openings can also mitigate potential property and personal safety risks.

[0054] In a preferred embodiment, the air outlet of the fresh air system and the air outlet 114 of the main body can be arranged vertically, and the air blown out can be mixed. This can increase the air volume while avoiding direct blowing, thereby preventing the user from being affected by direct blowing air and making the air output gentle, greatly improving the user experience.

[0055] The aforementioned triangular support 210, left column support 220, right column support 230, transverse column support 240, reinforcement support 250, front column support 260, and rear column support 270 can all be considered support assemblies. These multiple support assemblies work together to enhance the stability of the vertical air conditioner indoor unit 100. The specific assembly sequence of the air duct plate 120, the various support assemblies, and the housing 110 of the vertical air conditioner indoor unit 100 of this embodiment can be referenced in the following specific embodiments.

[0056] In a specific embodiment, the left column support 220 and the right column support 230 can be fixed to the base 116 first, and then the triangular support 210 and the horizontal column support 240 can be fixedly assembled into a triangle, and then the triangle can be pushed in from the rear of the left column support 220 and the right column support 230, and then the triangle can be fixed to the air duct plate 120 and the left column support 220 and the right column support 230 respectively.

[0057] The left and right column supports 220 and 230 are fixed to the base 116. Since the base 116 is part of the housing 110, it actually fixes the left and right column supports 220 and 230 to the housing 110. The triangular support 210 and the horizontal column support 240 are fixedly assembled to form a triangle. The stable triangular shape makes the air duct plate 120 more stable, effectively improving the stability of the air duct plate 120, and further improving the overall stability of the vertical air conditioner indoor unit 100, preventing the vertical air conditioner indoor unit 100 from bending and deformation during transportation and falling.

[0058] In fact, Figure 7 The figure shows the triangle formed by the fixed assembly of the triangular support 210 and the horizontal column support 240. The triangle is pushed in from behind the left column support 220 and the right column support 230, and then fixed to the air duct plate 120 and the left column support 220 and the right column support 230 respectively. This effectively utilizes the gap between the left column support 220 and the right column support 230, making it possible to install the triangular support 210 and the horizontal column support 240. The assembly method is scientific and reasonable, saving the time and energy of the installers and improving assembly efficiency.

[0059] Furthermore, since the triangle is composed of the triangular support 210 and the horizontal column support 240, fixing the triangle to the air duct plate 120 and the left column support 220 and the right column support 230 respectively means fixing the triangular support 210 to the air duct plate 120 and the horizontal column support 240 to the left column support 220 and the right column support 230. Ultimately, however, these components form a stable whole.

[0060] In another specific embodiment, the left column support 220, the right column support 230, the front column support 260 and the rear column support 270 can be fixed to the base 116; the heat exchanger can be fixed to the left column support 220 and the right column support 230; the air duct plate 120 can be fixed to the front column support 260; the first connecting portion 216 can be fixed to the third support portion 241 by screws; the second connecting portion 217 can be fixed to the third support portion 241 by screws, so as to fix the triangular support 210 and the horizontal column support 240 to be assembled into a triangle.

[0061] Then, push the triangle in from the rear of the left column support 220 and the right column support 230; fix the third connecting portion 242 to the left column support 220 by screws; fix the fourth connecting portion 243 to the right column support 230 by screws to fix the triangle to the left column support 220 and the right column support 230; fix the mounting portion 214 to the reinforcing support 250 by screws to fix the triangle to the air duct plate 120; fix the control box in the space below the air duct plate 120; fix multiple accessories in the cavity 118; fix the left column support 220 to the left panel 112, and fix the right column support 230 to the right panel 113.

[0062] It should be noted that fixing the left column support 220, the right column support 230, the front column support 260 and the rear column support 270 to the base 116 is actually fixing the left column support 220, the right column support 230, the front column support 260 and the rear column support 270 to the shell 110.

[0063] The third connecting portion 242 is fixed to the left column support 220 by screws, and the fourth connecting portion 243 is fixed to the right column support 230 by screws. Since the third connecting portion 242 and the fourth connecting portion 243 are part of the transverse column support 240, they actually fix the transverse column support 240 to the left column support 220 and the right column support 230. The mounting portion 214 is fixed to the reinforcing support 250 by screws to fix the triangle to the air duct plate 120. Since the mounting portion 214 is part of the triangular support 210 and the reinforcing support 250 is part of the air duct plate 120, they actually fix the triangular support 210 to the air duct plate 120.

[0064] Since the triangular support 210 and the transverse column support 240 are fixedly assembled to form a triangle, that is, the triangular support 210 and the transverse column support 240 are both parts of the triangle, then fixing the transverse column support 240 to the left column support 220 and the right column support 230, and fixing the triangular support 210 to the air duct plate 120, actually completes the fixing of the triangle to the air duct plate 120, the left column support 220, and the right column support 230.

[0065] First, the triangle is fixed to the left and right column supports 220, 230, and the air duct plate 120. Then, the control box is fixedly installed in the space below the air duct plate 120, and the multiple accessories are fixedly installed in the cavity 118. This is because the triangle support 210 and the horizontal column support 240 are installed and fixed first, and then the control box and multiple accessories are installed. This makes the assembly sequence reasonable. The triangle support 210 and the horizontal column support 240 do not occupy the installation space of the control box and multiple accessories, and do not affect the installation difficulty of the control box and multiple accessories.

[0066] The left column support 220 is fixed to the left panel 112, and the right column support 230 is fixed to the right panel 113. Since the left column support 220 and the right column support 230 have been fixed to the base 116 before, the overall stability of the vertical air conditioner indoor unit 100 can be improved.

[0067] In a preferred embodiment, the front panel 111, left panel 112, and right panel 113 of the housing 110 can be formed into a single integral housing. After all components within the cavity 118 of the vertical air conditioner indoor unit 100 of this embodiment are assembled, the housing can be installed and secured to the base 116. Finally, the rear panel can also be secured to the base 116. The tops of the housing and rear panel can together form a top cover 117, allowing the housing 110 to completely enclose the internal components, thus completing the overall installation of the vertical air conditioner indoor unit 100.

[0068] In summary, the vertical air conditioner indoor unit 100 of this embodiment includes: a shell 110, which defines a cavity 118 therein; an air duct plate 120, arranged inside the cavity 118 and configured to define an air duct as a duct assembly; and a triangular support 210, arranged inside the cavity 118 and fixedly connected to the air duct plate 120, and the triangular support 210 includes a first support portion 211 and a second support portion 212, and there is an angle between the first support portion 211 and the second support portion 212. By providing the triangular support 210, the air duct plate 120 can be made more stable through the stable triangular shape, effectively improving the stability of the air duct plate 120, and thereby improving the overall stability of the vertical air conditioner indoor unit 100, thereby preventing the vertical air conditioner indoor unit 100 from bending and deforming during transportation and falling.

[0069] Furthermore, in the vertical air conditioner indoor unit 100 of this embodiment, a transverse column support 240 is provided between the left column support 220 and the right column support 230, and the transverse column support 240 is connected to the air duct plate 120 by a triangular support 210. The installer only needs to screw sideways to achieve the connection and fixation, and the assembly method is simple and convenient; during the transportation, falling and impact of the vertical air conditioner indoor unit 100, the load-bearing part 215 of the triangular support 210 is used to support and bear the force, making the air duct plate 120 more stable and not crushed. The reinforced support 250 provided on the lower half of the air duct plate 120, especially the grid rib 251 provided on the reinforced support 250, can further prevent the air duct plate 120 from bending. Within the limited installation space, without changing the original structure inside the cavity 118 of the shell 110, by establishing a support component with a scientific and reasonable structure, the force transmission path of the air duct plate 120 is optimized and its overall rigidity is increased.
