When the gas output by the fan wheel assembly passes through the partition plate, the air velocity is high and the air outlet area is relatively concentrated, which is not conducive to heat exchange between the airflow and the heat exchange structure, resulting in low heat exchange efficiency of the indoor unit.

[0026] (3) H4 < 2H3, then 8° ≤ α1 ≤ 25°, 5° ≤ α2 ≤ 15°.

[0027] In some embodiments, the number of folding units is two, arranged side by side along the second direction, and both folding units include a first folding portion and a second folding portion disposed opposite to each other in the second direction; or,

[0028] The number of folding units is greater than two and they are arranged side by side along the second direction. In the second direction, the folding unit located in the edge region of the first straight portion includes a first folding portion and a second folding portion arranged opposite each other in the second direction, and the folding unit located in the middle region of the first straight portion includes two second folding portions arranged opposite each other in the second direction.

[0029] In some embodiments, in the same folding unit, one of the two folding portions arranged opposite each other along a direction perpendicular to the parallel arrangement of the plurality of folding units is a third folding portion and the other is a fourth folding portion, and at least one of the third folding portion and the fourth folding portion includes the second folded edge.

[0030] In some embodiments, the partition plate further includes a transition plate and a first flange, wherein the transition plate and the first flange are spaced apart and disposed on the side of the first straight portion facing the second folded edge;

[0031] The edges of the first straight section, which connect the transition plate and the first flange, are spaced apart from the folding unit.

[0032] In some embodiments, the first straight portion is integrally disposed with the folding portion; and / or, two adjacent folding portions of the same folding unit are spaced apart.

[0033] Secondly, this application provides an indoor unit, which is a ducted air conditioner. The indoor unit includes a partition and a volute as described above. The volute includes an air outlet end, which has an air vent. The air outlet end is located at the partition outlet of the partition and installed on the partition. The second folded edge of the folding part is configured to diffuse and guide the gas output from the air vent.

[0034] In some embodiments, the second folded edge is spaced apart from the air outlet end along the thickness direction of the partition plate.

[0040] Based on the partition, indoor unit, and HVAC system of this application embodiment, the gas flowing out of the partition outlet of the partition can be diffused at the second fold. The flow velocity of the gas after passing through the second fold is reduced, and the airflow uniformity is better. It can exchange heat with the heat exchange structure of the indoor unit at a more suitable speed and airflow uniformity, thereby improving the heat exchange efficiency of the indoor unit. At the same time, the second fold can also constrain the gas flowing out of the partition outlet in a timely manner. The second fold forms a diffusion buffer zone to prevent the airflow flowing out of the partition outlet from suddenly becoming unconstrained and scattering outside the partition outlet, interfering with the stability of the airflow flow. The second fold guides more airflow to flow orderly towards the side of the first straight section facing the second fold, so that more of the gas output from the partition outlet can reach the vicinity of the heat exchange structure of the indoor unit, improving the utilization rate of the airflow output from the partition outlet, thereby further improving the heat exchange efficiency of the indoor unit.

[0072] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0073] In related technologies, the fan assembly of the indoor unit of a HVAC system is installed on a partition plate, which provides support for the fan assembly. However, when the gas output from the fan assembly passes through the partition plate, the airflow velocity is high, the airflow area is relatively concentrated, and the contact time with the heat exchange structure is short when flowing near it, which is not conducive to heat exchange between the airflow and the heat exchange structure, resulting in low heat exchange efficiency of the indoor unit. For example, the end of the folded portion at the partition plate outlet is flush with or shorter than the air outlet end of the fan assembly's volute. The folded portion only supports the air outlet end of the volute and has no guiding effect on the airflow output from the air outlet end of the volute, resulting in low heat exchange efficiency of the airflow flowing through the heat exchange structure. Based on this, embodiments of this application provide a partition plate, an indoor unit, and an HVAC system.

[0074] In this application embodiment, the HVAC system includes, but is not limited to, air conditioning, multi-split systems, and heat pumps, and can be applied to large-scale venues such as shopping malls and office buildings. The HVAC system may include an indoor unit, an outdoor unit, and connecting pipes. The indoor unit is connected to the outdoor unit via connecting pipes to create a refrigerant circulation between the two units. In some practical applications, the indoor unit can be installed indoors, while the outdoor unit is responsible for cooling or heating, transporting refrigerant through connecting pipes. The refrigerant then exchanges heat with both indoor and outdoor air. The indoor unit is responsible for delivering cool or warm air into the room to achieve cooling or heating effects.

[0075] In the embodiments of this application, the indoor unit may include, but is not limited to, ducted air conditioners, wall-mounted air conditioner indoor units, and floor-standing air conditioner indoor units. Among them, ducted air conditioners are usually installed on the ceiling and can be hidden inside the ceiling, so that the indoor unit has a better hiding effect and is more aesthetically pleasing compared to other indoor unit structures. In addition, ducted air conditioners use decentralized air outlets, which makes the air outlet effect more comfortable.

[0076] like Figure 1 The diagram shown is a structural schematic of an indoor unit 1 according to an embodiment of this application. The indoor unit 1 includes a partition 200, a motor assembly 400, and a fan assembly 300. Figure 2 As shown, both the motor assembly 400 and the impeller assembly 300 are installed on the partition plate 200. The impeller assembly 300 includes an impeller and a volute 310. The impeller is located inside the air cavity of the volute 310. The motor assembly 400 is connected to the impeller and is used to control the operation of the impeller. When the impeller rotates, it drives the air flow inside the air cavity, thereby driving the air inside the indoor unit 1 into the room to regulate the indoor temperature.

[0077] The partition 200 includes a first plate 210, which includes a first straight portion 211 and at least one set of folding units 202, such as... Figure 3 and Figure 4 As shown, each folding unit 202 includes multiple folding portions 212, which are disposed on one side of the first straight portion 211. The folding portions 212 are connected to the first straight portion 211 and are bent relative to the first straight portion 211. For example... Figure 5 As shown, the multiple folding portions 212 of the folding unit 202 and the first straight portion 211 enclose a partition outlet 202a. The partition outlet 202a is configured as the air outlet 311 of the volute 310 of the indoor unit 1. The air outlet 311 has an air cavity outlet. The gas flowing out from the air cavity outlet passes through the evaporator 800 and then flows out of the indoor unit 1 from the indoor air outlet 1010. The air outlet 311 can be installed on the middle partition 200, which provides support for the air outlet 311 of the volute 310.

[0078] The surface of the folding portion 212 adjacent to the first straight portion 211 is configured to contact the surface of the air outlet 311, while the portion of the folding portion 212 away from the first straight portion 211 is configured to be spaced apart from the air outlet 311. The folding portion 212 provides support for the air outlet 311 of the volute 310 and restricts the position of the air outlet 311, further improving the installation stability of the air outlet 311 of the volute 310, so that the partition plate 200 can support the impeller assembly 300 and the motor assembly 400.

[0079] like Figure 5 and Figure 6As shown, the folding portion 212 includes a first folded edge 2121 connected to the first straight portion 211, and the first folded edges 2121 of the multiple folding portions 212 of each folding unit 202 and the first straight portion 211 enclose to form a partition outlet 202a. The partition outlet 202a is configured to accommodate the air outlet end 311 of the volute 310 of the indoor unit 1, providing support for the air outlet end 311 of the volute 310. Among them, at least one of the folding portions 212 of each folding unit 202 also includes a second folded edge 2122. The second folded edge 2122 is connected to the end of the first folded edge 2121 away from the first straight portion 211. Along the thickness direction (first direction X) of the middle partition 200, the second folded edge 2122 is spaced apart from the air outlet end 311, so that the second folded edge 2122 is only used to guide the airflow blown out of the air outlet end 311 of the volute 310, and is not used to restrict the position of the air outlet end 311 of the volute 310.

[0080] The second fold 2122 is inclined away from the first fold 2121 towards the side away from the partition outlet 202a. This allows the gas flowing out of the partition outlet 202a to be diffused at the second fold 2122. The flow velocity of the gas after passing through the second fold 2122 is reduced, and the airflow uniformity is better. This allows for heat exchange with the heat exchange structure of the indoor unit 1 at a more suitable velocity and with better airflow uniformity. The flow resistance after passing through the heat exchange structure is also reduced, improving the heat exchange efficiency of the indoor unit 1. At the same time, the second fold 2122 can also timely reduce the flow velocity of the gas at the partition outlet 202a. The gas is constrained to prevent the airflow from the baffle outlet 202a from suddenly becoming unconstrained and scattering outside the baffle outlet 202a, thus interfering with the stability of the airflow. A diffusion buffer zone is formed at the second fold 2122, which guides more airflow to flow orderly towards the side of the first straight section 211 facing the second fold 2122. This allows more gas output from the baffle outlet 202a to reach the vicinity of the heat exchange structure of the indoor unit 1, improving the utilization rate of the airflow output from the baffle outlet 202a and further improving the heat exchange efficiency of the indoor unit 1.

[0081] In addition, by setting at least part of the folding portion 212 to include a first fold 2121 and a second fold 2122, that is, the folding portion 212 has a two-section bending structure, the folding portion 212 can also have better structural strength, providing stable support for the air outlet end 311 of the volute 310.

[0082] To ensure that the second fold 2122 can effectively diffuse and guide the gas output from the baffle outlet 202a, such as Figure 7As shown, the angle between the extension directions of the second fold 2122 and the first fold 2121 is set to α (including α1 and α2), where α satisfies: 5°≤α≤30°. For example, α can be 5°, 10°, 15°, 25°, 30°, or any range of the above. When α is less than 5°, the angle is too small, and the airflow cannot achieve effective diffusion and deceleration when passing through the second fold 2122. The airflow will still reach the vicinity of the heat exchange structure of the indoor unit 1 at a relatively high speed, and the airflow distribution will be uneven. When α is greater than 30°, the deflection degree of the second fold 2122 is too large, and the second fold 2122 will have a poor constraint and guidance effect on the airflow, which will easily lead to a smaller airflow reaching the heat exchange structure of the indoor unit 1, thereby resulting in a large power consumption of the indoor unit 1.

[0083] The air outlet 311 of the volute 310 is located inside the partition outlet 202a. The airflow output from the air outlet 311 of the volute 310 eventually flows out of the partition outlet 202a from the end of the first folded edge 2121 away from the first straight portion 211. The extension direction of the first folded edge 2121 will affect the direction of the airflow flowing out of the partition outlet 202a. In some embodiments, the first folded edge 2121 extends along a first direction X perpendicular to the surface of the first straight portion 211, so that the airflow flows along the direction perpendicular to the surface of the first straight portion 211 towards the side where the second folded edge 2122 is located. There is a larger flow space in the direction perpendicular to the surface of the first straight portion 211, so that there is a suitable flow to reach the heat exchange structure and prevent the airflow from colliding with other structures of the indoor unit 1 when it flows in a direction that is at an angle to the first direction X, resulting in airflow loss.

[0084] In this embodiment, at the same partition outlet 202a, the first straight portion 211 and the first folded edge 2121 of the folded portion 212 jointly provide support for the air outlet end 311 of the volute 310. Specifically, the first folded edge 2121 of a portion of the folded portion 212 of the same folding unit 202 can contact the air outlet end 311 of the volute 310, thereby providing support for the air outlet end 311 of the volute 310. Alternatively, the first folded edges 2121 of all the folded portions 212 of the same folding unit 202 can provide support for the air outlet end 311 of the volute 310. In this case, the first folded edges 2121 of the multiple folded portions 212 of the same folding unit 202 can be arranged in parallel directions so that the air outlet end 311 of the volute 310 can be inserted between the multiple folded portions 212, facilitating assembly and disassembly.

[0085] In this embodiment of the application, when the indoor unit 1 is a ducted air conditioner, the heat exchange structure may include an evaporator 800. The evaporator 800 is located on the side of the first straight portion 211 facing the second folded edge 2122. The second folded edge 2122 of the folded portion 212 is configured to diffuse and guide the gas output from the air outlet to the evaporator 800.

[0086] In some embodiments, the middle partition 200 comprises a folding unit 202, correspondingly, the middle partition 200 is formed with a partition outlet 202a, and the folded portions 212 of the folding unit 202 may both be provided with a second folded edge 2122.

[0087] In some embodiments, the middle partition 200 comprises a plurality of folding units 202, correspondingly, the middle partition 200 is formed with a plurality of partition outlets 202a. It can be understood that after the airflow exits from two adjacent partition outlets 202a, the crosstalk in the direction in which two adjacent folding units 202 are arranged side by side is relatively large, especially the airflow crosstalk in the area between two adjacent partition outlets 202a is even greater, which will affect the stability of airflow flow. Therefore, it is necessary to consider reducing the crosstalk of airflow in the direction in which two adjacent folding units 202 are arranged side by side after the airflow passes through the partition outlets 202a. As Figure 7 shown, in the same folding unit 202, along the direction in which two adjacent folding units 202 are arranged side by side, one of the two oppositely arranged folded portions 212 is a first folded portion 2021, and the other is a second folded portion 2022. The first folded portion 2021 is disposed toward the edge of the first flat portion 211, the second folded portion 2022 is disposed toward the adjacent folding unit 202, and both the first folded portion 2021 and the second folded portion 2022 comprise a second folded edge 2122. The airflow in the direction where two adjacent folding units 202 are arranged side by side is diffused and guided through the second folded edge 2122, so as to reduce the airflow crosstalk in the direction where two adjacent folding units 202 are arranged side by side.

[0088] Since the airflow crosstalk in the area between two adjacent partition outlets 202a is greater, when the same folding unit 202 comprises the first folded portion 2021 and the second folded portion 2022, in a first direction X perpendicular to the plate surface of the first flat portion 211, the height of the first folded portion 2021 is H1, the height of the second folded portion 2022 is H2, and H1 and H2 satisfy: H1≤H2. When H1<H2, the second folded portion 2022 has a longer flow path for guiding airflow, which can delay the confluence time of the airflows blown out from two adjacent partition outlets 202a, thereby reducing the interference between the airflows blown out from two adjacent partition outlets 202a.

[0089] In some embodiments, in the first direction X, the height of the second folded edge 2122 of the first folded portion 2021 is h1, the height of the second folded edge 2122 of the second folded portion 2022 is h2, and h1 and h2 satisfy: h1≤h2. When h1<h2, the second folded edge 2122 can diffuse the airflow in the regions adjacent to each other of two adjacent partition outlets 202a in advance, so that for the airflow flowing out from two adjacent partition outlets 202a, the interference at the confluence of the airflows blown out from two adjacent partition outlets 202a can be better reduced.

[0090] Wherein, in the embodiments of the present application, regarding the heights of respective parts of the first folding portion 2021 and the second folding portion 2022, the following conditions may also exist: (1) H1=H2 and h1=h2; (2) H1=H2 and h1<h2; (3) H1<H2 and h1=h2; (4) H1<H2 and h1<h2. Under the above four conditions, air flow crosstalk in the direction where two adjacent folding units 202 are arranged side by side can be reduced.

[0091] In some embodiments, in the first direction X, the height of the first folded edge 2121 of the first folding portion 2021 is a1, a1=H1-h1, where 10mm≤H1-h1≤20mm and 25mm≤H1≤75mm. Within the above height range, the first folded edge 2121 of the first folding portion 2021 can provide good support and limiting for the air outlet end 311 of the volute 310, and meanwhile, the first folding portion 2021 also has a suitable height to guide the flow direction of air flow.

[0092] In some embodiments, in the first direction X, the height of the first folded edge 2121 of the second folding portion 2022 is a2, a2=H2-h2, where 10mm≤H2-h2≤20mm and 25mm≤H2≤75mm. Within the above height range, the first folded edge 2121 of the second folding portion 2022 can also provide good support and limiting for the air outlet end 311 of the volute 310, and make the height of the first folded edge 2121 of the second folding portion 2022 appropriate, thereby enabling the second folded edge 2122 of the second folding portion 2022 to obtain a suitable height to guide the flow direction of air flow and reduce air flow crossing between two adjacent folding units 202.

[0093] It can be understood that, under the guiding action of the second folded edge 2122, the air flow blown out from the partition outlet 202a is divergent. The larger the included angle between the second folded edge 2122 and the extending direction (the first direction X) of the first folded edge 2121 (the inclination angle α of the second folded edge 2122 relative to the first folded edge 2121) is, the larger the divergence angle of the air flow after passing through the second folded edge 2122 is. However, the larger the divergence angle is, the higher the probability that two adjacent air flows intersect and the higher the probability that the air flow collides with the wall surfaces of other structures of the indoor unit 1 is. Moreover, the probability of such air flow intersection or collision between air flow and the wall surfaces of other structures is related to the distance of the folding unit 202 relative to other structures and the inclination angle of the second folded edge 2122. Therefore, in the embodiments of the present application, the distance of the folding unit 202 relative to other structures and the inclination angle of the second folded edge 2122 are selected to reduce the probability of mutual crosstalk or collision of gas.

[0094] In some embodiments, as Figure 8 and Figure 9As shown, in the direction where two adjacent folding units 202 are arranged side by side, the distance between the first folded edge 2121 of the first folding part 2021 and the edge of the adjacent first straight part 211 is H3, and the distance between the first folded edges 2121 of the second folding parts 2022 of the two adjacent folding units 202 is H4. The angle between the second folded edge 2122 of the first folding part 2021 and the first direction X is α1, and the angle between the second folded edge 2122 of the second folding part 2022 and the first direction X is α2. The first direction X is parallel to the thickness direction of the partition plate 200. The partition plate 200 satisfies one of the following conditions:

[0095] (1) If H4 = 2H3, then α2 = α1;

[0096] (2) If H4 > 2H3, then α1 < α2;

[0097] (3) If H4 < 2H3, then α1 > α2.

[0098] When the above conditions are met, the spacing between two adjacent folding units 202, the spacing between the folding unit 202 and the edge of the first straight portion 211, and the inclination angle of the second folded edge 2122 relative to the first folded edge 2121 are appropriate. This allows the airflow blown from the partition outlet 202a to receive appropriate diffusion and guidance after passing through the second folded edge 2122, converting dynamic pressure into static pressure, reducing the degree of airflow crosstalk, allowing the airflow to obtain a suitable velocity, and making the airflow more evenly dispersed. As a result, when the airflow passes through the heat exchange structure of the indoor unit 1, the resistance is small, thereby improving the working efficiency of the device driving the airflow, reducing power consumption, improving the heat exchange efficiency of the heat exchange structure, and further improving the energy efficiency of the indoor unit 1. In the embodiments of this application, the device driving the airflow includes, but is not limited to, a motor assembly.

[0099] Furthermore, the partition 200 satisfies one of the following conditions:

[0100] (1) H4 = 2H3, then 8° ≤ α2 = α1 ≤ 25°;

[0101] (2) If H4 > 2H3, then 5° ≤ α1 ≤ 15°, and 8° ≤ α2 ≤ 25°;

[0102] (3) H4 < 2H3, then 8° ≤ α1 ≤ 25°, 5° ≤ α2 ≤ 15°.

[0103] When the above conditions are met, under the corresponding spacing, selecting the second folded edge 2122 with a suitable tilt angle can further improve the heat exchange efficiency, improve the working efficiency of the device driving the airflow, and reduce power consumption.

[0104] In this embodiment of the application, when there are multiple folding units 202, the multiple folding units 202 can be arranged side by side in the same direction.

[0105] In some embodiments, such as Figure 8 As shown, when there are two folding units 202, the two folding units 202 are arranged side by side along the second direction Y. Each of the two folding units 202 includes a first folding portion 2021 and a second folding portion 2022 arranged opposite to each other in the second direction Y. In the second direction Y, the second folding portions 2022 of the two folding units 202 are arranged close to each other, and the first folding portions 2021 of the two folding units 202 are arranged away from each other, so that the first folding portions 2021 of the two folding units 202 are arranged near the edge of the first straight portion 211.

[0106] In some embodiments, such as Figure 9 As shown, when the number of folding units 202 is greater than two, multiple folding units 202 are arranged side by side along the second direction Y. In the second direction Y, the folding unit 202 located at the edge region of the first straight portion 211 includes a first folding portion 2021 and a second folding portion 2022 arranged opposite to each other in the second direction Y. The folding unit 202 located in the middle region of the first straight portion 211 includes two second folding portions 2022 arranged opposite to each other in the second direction Y. Similarly, the first folding portion 2021 of the folding unit 202 located at the edge region of the first straight portion 211 is arranged toward the edge of the first straight portion 211, and the second folding portion 2022 is arranged toward the folding unit 202 located in the middle region.

[0107] In some other embodiments, when the number of folding units 202 is greater than two, some of the folding units 202 may be arranged side by side along the second direction Y, and other folding units 202 may be arranged side by side along the third direction. Some of the folding units 202 may include a first folding part 2021 and a second folding part 2022, and the first folding part 2021 may be arranged toward the edge of the first straight part 211. Furthermore, some folding units 202 may include two, three, or four second folding parts 2022, and the second folding parts 2022 of each folding unit 202 may be arranged toward the adjacent folding unit 2022.

[0108] In some embodiments, when multiple reflective folding units 202 are arranged side by side along the same direction, the same folding unit 202 may include four folding portions 212. In the same folding unit 202, along a direction perpendicular to the direction in which the multiple folding units 202 are arranged side by side, such as... Figure 10As shown, one of the two opposing folding portions 212 is a third folding portion 2023 and the other is a fourth folding portion 2024. At least one of the third folding portion 2023 and the fourth folding portion 2024 includes a second fold edge 2122. The second fold edge 2122 of the third folding portion 2023 and the fourth folding portion 2024 also diffuses and guides the airflow output from the partition outlet 202a, guiding the airflow to flow at a suitable speed and in a uniform and stable manner.

[0109] Optionally, multiple folding units 202 are arranged side by side along the second direction Y, and the third folding part 2023 and the fourth folding part 2024 are arranged opposite each other along the third direction Z. Along the third direction Z, when one of the third folding part 2023 and the fourth folding part 2024 is closer to one edge of the first straight part 211 and the other is farther from the other edge of the first straight part 211, the inclination angle α of the second folding edge 2122 of the closer folding part 212 is set to be smaller than the inclination angle α of the second folding edge 2122 of the farther folding part 212. Thus, the airflow after passing through the folding unit 202 is guided by the second folding edge 2122 of the third folding part 2023 and the fourth folding part 2024, so that the airflow reaches the heat exchange structure at a suitable angle. In this embodiment, there are no restrictions on the size of the inclination angle α of the second fold 2122 of the third folding part 2023 and the second fold 2122 of the fourth folding part 2024, and the inclination angles both satisfy 5°≤α≤30°. Specifically, they can be selected according to the flow direction requirements of the airflow output from the partition outlet 202a.

[0110] In some embodiments, when the partition plate 200 further includes a transition plate 220 and a first flange 213, the transition plate 220 and the first flange 213 are arranged opposite to each other and spaced apart in the third direction Z. The transition plate 220 and the first flange 213 are disposed on the side of the first straight portion 211 facing away from the second folded edge 2122. The first straight portion 211 has a first edge and a second edge arranged opposite to each other in the first direction X. The first flange 213 is connected to the first edge, and the transition plate 220 is connected to the second edge. The third folded portion 2023 is disposed toward the first edge of the first straight portion 211 connected to the first flange 213, and the fourth folded portion 2024 is disposed toward the second edge of the first straight portion 211 connected to the transition plate 220. That is, the folding unit 202 is spaced apart from the edge of the first straight portion 211 connected to the transition plate 220 and the edge connected to the first flange 213, respectively. In the third direction Z, the distance from the third folding part 2023 to the first edge is less than the distance from the fourth folding part 2024 to the second edge. The inclination angle of the second folding edge 2122 of the third folding part 2023 can be set to be less than the inclination angle of the second folding edge 2122 of the fourth folding part 2024, so that the airflow output from the partition outlet 202a is more dispersed to the side where the second edge is located, so as to make full use of the space to diffuse the airflow output from the partition outlet 202a and reduce the collision between the airflow output from the partition outlet 202a and other structures of the indoor unit 1.

[0111] In this embodiment, the first straight portion 211 and the folded portion 212 are integrally formed. The folded portion 212 can be formed by folding a plate connected to the first straight portion 211, giving the folded portion 212 good structural strength. In other embodiments, the first folded edge 2121 of the folded portion 212 can also be fixedly installed to the first straight portion 211 by welding, threaded connection, or other methods. Adjacent folded portions 212 of the same folding unit 202 are spaced apart to flexibly set the shape of each folded portion 212 of the folding unit 202, thereby facilitating the fulfillment of various diffusion and flow guidance requirements. Additionally, it also facilitates the insertion of the air outlet 311 of the volute 310 into the partition outlet 202a, simplifying assembly.

[0112] like Figure 11As shown, the partition 200 also includes a second plate 230 and a transition plate 220. The first plate 210 includes a first straight portion 211, which is configured for mounting the motor assembly 400 and the fan assembly 300 of the indoor unit 1. The first straight portion 211 has a first side facing the motor assembly 400. The second plate 230 is disposed on the first side of the first straight portion 211 and is spaced apart from the first straight portion 211. The transition plate 220 is disposed between the first straight portion 211 and the second plate 230 and is connected to the first straight portion 211 and the second plate 230 respectively, so that the second plate 230 and the transition plate 220 form a stepped structure 201. The stepped surface of the stepped structure 201 is configured for mounting external structures.

[0113] Please refer to the following: Figure 1 This is a schematic diagram of the structure of the indoor unit 1 when installed in the working position in one embodiment of this application. The partition 200 is placed vertically, that is, the first side of the first flat part 211 is the rear side of the first flat part 211, the motor assembly 400 is located on the rear side of the flat part, and at least part of the impeller of the impeller assembly 300 and the volute 310 is located on the rear side of the first flat part 211. When the impeller is running, the impeller drives the airflow inside the volute 310 to flow toward the front side of the first flat part 211, and then flows out of the indoor unit 1 and into the room. Figure 1 In the vertical direction, the first plate 210 is located above the second plate 230, and the transition plate 220 can be supported by the external structure, so that the external structure can provide support for the partition plate 200 in the vertical direction and prevent the partition plate 200 from shaking. In this way, even if the first plate 210 and the second plate 230 of the partition plate 200 are not fixed to the external structure, the partition plate 200 will not shake or fall with the motor assembly 400 and the fan wheel assembly 300. Moreover, only a small force is needed to limit the position of the partition plate 200, which facilitates the disassembly, assembly and maintenance of the partition plate 200.

[0114] like Figure 12 The diagram shown is a three-dimensional structural schematic of the indoor unit 1 during the assembly process in one embodiment of this application. Figure 12 In the vertical direction, the first plate 210 is located above the second plate 230. Thus, the step structure 201 formed by the transition plate 220 and the second plate 230 can provide support for the external structure, which facilitates the assembly of the external structure and helps to improve the assembly efficiency of the entire indoor unit 1.

[0115] In addition, the transition plate 220 of the partition 200 is set at an angle to the first plate 210 and the second plate 230, which can increase the structural strength of the entire partition 200. When heavy structural components such as the motor assembly 400 and the fan wheel assembly 300 are installed on the partition 200, the partition 200 is not easily pulled and deformed. This allows the motor assembly 400, the fan wheel assembly 300 and the partition 200 to be assembled into one unit and then moved, which helps to improve the assembly efficiency of the entire indoor unit 1.

[0116] The first straight section 211 also has a second side. The first side and the second side of the first straight section 211 are two sides of the first straight section 211 opposite to each other in the first direction X. When the indoor unit 1 is in the working position, the first direction X can be either the front-rear direction of the first straight section 211 or the front-rear direction of the indoor unit 1. Figure 1 and Figure 13 The middle part of the first straight section 211 is configured for mounting the motor assembly 400 and the fan assembly 300 of the indoor unit 1. In the second direction Y, which is perpendicular to the first direction X, the two opposite edge parts of the first straight section 211 are respectively provided with first mating parts 2111. The first mating parts 2111 are configured to be assembled with the external structure located on the second side of the first straight section 211 to install the partition plate 200 on the external structure. For example, the external structure can be the sealing side plate 701 of the indoor unit 1. The sealing side plate 701 is assembled with the evaporator 800 of the indoor unit 1. The evaporator 800 is located on the second side of the first straight section 211. The gas output by the fan assembly 300 can pass through the outside of the evaporator 800 and be output from the indoor unit 1 after the temperature is regulated by the evaporator 800. During maintenance, the partition plate 200 can be removed from the sealing side plate 701 for maintenance without removing the entire indoor unit 1.

[0117] In some embodiments, the first mating part 2111 is configured to be assembled with the external structure using at least one of the following methods: hooking, snapping, and screw connection, to define the position of the partition 200 relative to the external structure. When the first mating part 2111 is assembled with the external structure using methods that facilitate disassembly and assembly, such as hooking or snapping, it only defines the position of the partition 200 relative to the external structure and does not completely fix the position of the partition 200 relative to the external structure. This allows the partition 200 to be maintained in its installed position during disassembly and maintenance, even if it is not completely fixed to the external structure, preventing it from shaking or falling, and facilitating operation. In this application embodiment, the methods for fixing the partition 200 to the external structure include, but are not limited to, fixing the portion of the partition 200 with the first mating part 2111 using screw connection. Any method in the art that can fix the partition 200 to the external structure is applicable to this application.

[0118] When the first mating part 2111 of the partition 200 is configured to be assembled with the external structure by hooking, in one embodiment, such as Figure 13 As shown, the sealing side plate 701 has a second mating part 7011. One of the first mating part 2111 and the second mating part 7011 is a mating slot and the other is a mating hook. The mating hook passes through the mating slot and is hooked to the first straight part 211. By moving the partition plate 200 in a direction that forms an angle with the first direction X, the mating hook can be engaged with the mating slot or removed from the mating slot.

[0119] Optionally, the indoor unit 1 has two sealing side plates 701 disposed opposite each other in the second direction Y, such as Figure 13 and Figure 14 As shown, each sealing side plate 701 includes a first side portion 710, which has two mating hooks. The partition plate 200 has a set of latching units on its two opposite edge portions in the second direction Y. The two sets of latching units are arranged one-to-one with the two sealing side plates 701. Each set of latching units has two mating latches that correspond one-to-one with the two mating hooks of the corresponding sealing side plate 701. The two mating hooks of each sealing side plate 701 are bent in the third direction in a direction away from each other. The first direction X, the second direction Y and the third direction are perpendicular to each other. When disassembling or installing, the third direction is the up and down direction.

[0120] When assembling the indoor unit 1, the second plate 230 is located above the first plate 210. First, move the partition plate 200 close to the two sealing side plates 701 so that the mating hooks of the two sealing side plates 701 extend into the corresponding mating slots. Then, adjust the position of the partition plate 200 relative to the two sealing side plates 701 so that the mating hooks are engaged with the partition plate 200 and the surface of the partition plate 200 is in contact with the surface of the hooks, thereby limiting the position of the partition plate 200 relative to the two sealing side plates 701. When it is necessary to disassemble and repair the indoor unit 1 in the working position, the first plate 210 is located above the second plate 230. After first releasing the fixing of the middle partition 200 to the other structures of the indoor unit 1, the middle partition 200 is acted upon to move the mating hook out of the mating slot, and the middle partition 200 can be removed. After the repair is completed, the middle partition 200 is moved so that the mating hook passes through the mating slot, and the mating hook is hooked onto the middle partition 200 to pre-position the middle partition 200. Then, in conjunction with other installation methods, the position of the middle partition 200 relative to the sealing side plate 701 is fixed to complete the repair.

[0121] It should be noted that, in order to ensure the stable installation of the various structures of the indoor unit 1, the partition plate 200 is designed to fit against the surfaces of other structures. During disassembly and maintenance, the partition plate 200 may undergo a certain degree of deformation during the process of moving it, including but not limited to the partition plate 200 itself, in order to move the partition plate 200 to the required position.

[0122] like Figure 15 As shown, the first plate 210 includes a first flange 213, which is disposed on the second side of the first straight portion 211 and connected to the first straight portion 211, such that the first flange 213 and the first straight portion 211 are arranged at an angle, increasing the structural strength of the partition 200 and enabling the partition 200 to bear the weight of other structures. The first flange 213 is also configured to be assembled with external structures, increasing the contact area between the partition 200 and other structures, improving the installation stability of the partition 200, and, based on the angle between the first flange 213 and the first straight portion 211 to obtain greater structural strength, also improving the sealing stability of the partition 200 and other structures.

[0123] The first plate 210 also includes at least one second flange 214. The second flange 214 and the second plate 230 are located on the same side of the first straight portion 211, and the second flange 214 is connected to the first straight portion 211. The second flange 214 and the first straight portion 211 are arranged at an angle, which can also increase the structural strength of the partition plate 200. The first straight portion 211 and the second plate 230 are spaced apart in the first direction X. In the second direction Y, which is perpendicular to the first direction X, at least one of the two opposite side edges of the first straight portion 211 is provided with a second flange 214. The second flange 214 enhances the structural strength of the edge portion of the first straight portion 211. After the edge portion of the first straight portion 211 is assembled with the sealing side plate 700, the assembly stability of the edge portion of the first straight portion 211 and the sealing side plate 700 is improved. The second flange 214 is provided on the side of the first straight portion 211 away from the sealing side plate 700, which can also prevent the second flange 214 from interfering with the installation of the sealing side plate 700.

[0124] In this embodiment, the first plate 210 is a structure used to support the wind turbine assembly 300 and the motor assembly 400, and the size of the first plate 210 is relatively large. Therefore, the first plate 210 needs to have better structural strength to prevent deformation. Figure 15As shown, the first plate 210 also includes at least one first rib 215. The first rib 215 is disposed on the first straight portion 211 and protrudes towards the second side of the first straight portion 211 relative to the first straight portion 211, thereby further increasing the structural strength of the first straight portion 211. The first plate 210 may include multiple first ribs 215, so that the position of the first ribs 215 can be set according to the reinforcement requirements at different locations of the first plate 210, to prevent the first plate 210 from deforming.

[0125] Optionally, when the indoor unit 1 has two impeller assemblies 300, the first plate 210 is provided with two baffle outlets 202a corresponding to the two impeller assemblies 300. The air outlet end of the volute 310 of the impeller assembly 300 is set corresponding to the baffle outlet 202a. The airflow output by the impeller assembly 300 reaches the second side of the first straight section 211 at the baffle outlet 202a, and finally enters the room from the indoor outlet 1010 of the indoor unit 1. The volute 310 of the impeller assembly 300 is installed on the middle baffle 200, and its interaction with the middle baffle 200 can prevent deformation of the part of the middle baffle 200 where the impeller assembly 300 is installed. In the second direction Y, the motor assembly 400 is located between the two impeller assemblies 300. The motor assembly 400 is used to control the operation of the impellers of the two impeller assemblies 300. The motor assembly 400 is installed on the partition plate 200. Under the action of gravity, the motor assembly 400 has a tendency to fall, which can easily cause the partition plate 200 to be pulled. At least one first rib 215 is provided corresponding to the position of the motor assembly 400. That is, at least one first rib 215 is provided in the middle part of the first straight part 211 to enhance the structural strength of the part of the first straight part 211 where the motor assembly 400 is installed and prevent the first straight part 211 from being pulled and deformed by the motor assembly 400.

[0126] Optionally, the first rib 215 may have an open structure with shapes such as strip, wave, or arc; or, the first rib 215 may have a closed structure with shapes such as quadrilateral, rounded polygon, or circle. For example, Figure 15 As shown, the middle part of the first straight portion 211 is provided with a first rib 215. The first rib 215 is a rounded rectangle, and the first straight portion 211 is provided with a plurality of motor mounting portions 216 located outside the first rib 215. The motor assembly 400 is mounted on the motor mounting portion 216. That is, the first rib 215 is located in the area enclosed by the plurality of motor mounting portions 216, preventing the portion of the first straight portion 211 located between the plurality of motor mounting portions 216 from deforming.

[0127] Furthermore, the type of motor assembly 400 is not limited in the embodiments of this application. Any structure in the art that can drive the wind turbine assembly 300 to operate is applicable to this application.

[0128] In this embodiment, the second plate 230 is also used to be installed on the external structure. When the second plate 230 is subjected to the force of the external structure, the structural strength of the second plate 230 is poor and deformation may occur. Therefore, the second plate 230 also needs to have a certain structural strength so that the first plate 210, the transition plate 220 and the second plate 230 can interact with each other, so that the whole plate has good structural strength.

[0129] In some embodiments, such as Figure 15 As shown, the second plate 230 includes a second straight portion 231 and a third flange 232. The second straight portion 231 is connected to the transition plate 220, forming a stepped structure 201 with the transition plate 220. The third flange 232 is located on the side of the second straight portion 231 away from the first plate 210 and is connected to the edge of the second straight portion 231 away from the transition plate 220. This results in the partition plate 200 having a multi-bending structure, providing good structural strength and meeting the requirements for bearing heavy loads. The third flange 232 is also designed for installation on external structures, further increasing the contact area between the partition plate 200 and the external structure, thus improving the installation stability of the partition plate 200.

[0130] It is understood that the second straight portion 231 has a certain width in the third direction Z to allow the third flange 232 of the second plate 230 to be installed in a suitable position on the external structure. When the width of the second straight portion 231 in the third direction Z is large, if the structural strength of the second straight portion 231 is insufficient, it is also prone to deformation. In some embodiments, the second plate 230 also includes at least one second rib 233 provided on the second straight portion 231. The second rib 233 protrudes relative to the second straight portion 231 toward the side where the third flange 232 is located. The second rib 233 further enhances the structural strength of the second plate 230 and prevents the second plate 230 from deforming under external forces. Optionally, the second rib 233 has an open structure with shapes such as strip, wave, and arc; or the first rib 215 has a closed structure with shapes such as quadrilateral, rounded polygon, and circle.

[0131] In this embodiment, electrical components are disposed on opposite sides of the first straight portion 211. The structural components disposed on opposite sides of the first straight portion 211 are connected by wires, such as... Figure 15 and Figure 16 As shown, a wiring space 230a is formed in the corner area of ​​the second straight section 231 away from the transition plate 220. The wiring space 230a is used for cables to pass through, so that the wiring space 230a is spaced apart from the first plate 210 to maintain the structural integrity of the first plate 210 and give the first plate 210 good structural strength to support the heavy motor assembly 400 and wind turbine assembly 300.

[0132] In some embodiments, the indoor unit 1 further includes an electrical control box assembly 500, and the stepped structure 201 formed by the second plate 230 and the transition plate 220 is configured to be assembled with the electrical control box assembly 500. Multiple wires connected to the electrical control box assembly 500 can pass through the wiring space 230a. In addition, when the indoor unit 1 also includes an evaporator 800, the wires connected to the evaporator 800 can also pass through the wiring space 230a.

[0133] The wiring space 230a can be formed by hollowing out a portion of the second plate 230, such as... Figure 16 As shown, the routing space 230a can be an open space with an unclosed outer perimeter, or, as... Figure 17 As shown, the routing space 230a can also be a closed space with an outer perimeter shape such as a circle or rectangle.

[0134] Optionally, the second plate 230 has two wiring spaces 230a, and the partition 200 further includes two anti-scratch members 240. The two anti-scratch members 240 are provided one-to-one with the two wiring spaces 230a. The anti-scratch members 240 are wrapped around the edges of the wiring spaces 230a defined by the second plate 230 to prevent the wires passing through the wiring spaces 230a from being scratched. The anti-scratch members 240 can be made of flexible materials such as silicone or foam, and are fixed to the second plate 230 by means of bonding or snap-fitting.

[0135] In this embodiment, the first plate 210, the second plate 230, and the transition plate 220 are integrally formed, giving the partition plate 200 good structural strength. Furthermore, the partition plate 200 is a sheet metal part, giving it good bending resistance and enabling it to support structural components of considerable weight.

[0136] like Figure 18As shown, the indoor unit 1 also includes a top cover assembly 100 and a bottom cover assembly 600. The electrical control box assembly 500 and the bottom cover assembly 600 are located on the second side of the first straight portion 211 and arranged along the first direction X. The electrical control box assembly 500 and the bottom cover assembly 600 are respectively arranged opposite to the top cover assembly 100 in a third direction. A middle partition 200 is respectively installed on the electrical control box assembly 500 and the top cover assembly 100. The middle partition 200 has a partition outlet 202a. The electrical control box assembly 500, the top cover assembly 100, the bottom cover assembly 600, and the middle partition 200 are also respectively connected to two sealing sides. The plates 701 are assembled and together form a heat exchange cavity that communicates with the partition outlet 202a. A portion of the evaporator 800 is placed in the heat exchange cavity. The bottom cover assembly 600, the two sealing side plates 701, and the top cover assembly 100 also together form an indoor air outlet 1010 that communicates with the heat exchange cavity. In the first direction X, the middle partition 200 and the indoor air outlet 1010 are located on opposite sides of the evaporator 800. The gas output from the fan assembly 300 enters the heat exchange cavity through the partition outlet 202a, and after the temperature is adjusted by the evaporator 800, it flows out from the indoor air outlet 1010.

[0137] In some embodiments, such as Figure 19 As shown, the top cover assembly 100 includes a first reinforcing plate 112, a top cover substrate 111, and a second reinforcing plate 113 stacked sequentially along the thickness direction (third direction Z) of the top cover plate. The middle portion of the top cover substrate 111 and the first reinforcing plate 112 together form the top cover body. The gas output from the partition outlet 202a passes through the outside of the top cover body to the evaporator 800 and finally flows out from the indoor air outlet 1010. The top cover plate includes two second reinforcing plates 113. In a direction perpendicular to the thickness direction of the top cover plate, the two second reinforcing plates 113 are spaced apart from each other at opposite ends of the top cover base plate 111. Each second reinforcing plate 113, together with the end of the corresponding top cover base plate 111 and the end of the first reinforcing plate 112, forms a top cover mounting part. The top cover mounting part is configured to be installed on the external support structure to fix the position of the indoor unit 1 relative to the external support structure. The top cover mounting part is composed of more plates stacked together, which can obtain better support structure strength and is not easily deformed. The top cover assembly 100 can obtain better installation stability when installed on the external support structure.

[0138] In some embodiments, such as Figure 20As shown, the top cover substrate 111 includes a first substrate 1111, a first side plate 1113, and a second side plate 1114. A first reinforcing plate 112 and a second reinforcing plate 113 are respectively disposed on opposite sides of the first substrate 1111 along a third direction Z. The first side plate 1113 is disposed on the side of the first substrate 1111 facing the second reinforcing plate 113. The second side plate 1114 and the first side plate 1113 are disposed on the same side of the first substrate 1111, forming an angle with the first substrate 1111 and connecting to it, thereby enhancing the structural strength of the top cover assembly 100. In the first direction X, the second side plate 1114 is disposed opposite to the first side plate 1113 and is respectively connected to two sealing side plates 701. The first substrate 1111 and the first reinforcing plate 112 are configured to support the two sealing side plates 701, improving the installation stability of the two sealing side plates 701.

[0139] In the first direction X, a portion of the first plate 210 of the partition 200 is disposed on the inner side of the first side plate 1113 of the top cover substrate 111 (i.e., the side facing the second side plate 1114) and is in contact with the surface of the first side plate 1113. The first plate 210 can also be installed on the first side plate 1113. The first side portion 710 of the sealing side plate 701 is disposed on the second side of the first straight portion 211 and the partition 200 is installed thereon, so that the partition 200, the top cover assembly 100 and the sealing side plate 701 interact with each other, thereby improving the deformation resistance at the connection point and preventing air leakage at the connection point. In addition, when the partition 200 is not fixedly connected to the sealing side plate 701, the electrical control box assembly 500 and the top cover assembly 100, the first side plate 1113 can also restrict the position of the partition 200, prevent the partition 200 from tilting, and facilitate the disassembly and assembly of the partition 200.

[0140] The electrical control box assembly 500 includes an electrical control box body 510 and an electrical control module. The electrical control module is used to acquire and regulate the operating status of the indoor unit 1. The electrical control box body 510 has an electrical control cavity for accommodating the electrical control module, and the electrical control box body 510 is respectively mounted on the stepped structure 201 and the bottom cover assembly 600. In some embodiments, such as Figure 21 and Figure 22 As shown, the electrical control box 510 includes a first housing 511, a second housing 512, a third housing 513, and two fourth housings 514. The first housing 511 and the third housing 513 are arranged opposite each other in the third direction Z, and the first housing 511 is respectively installed on the stepped structure 201 and the bottom cover assembly 600. The second housing 512 and the second plate 230 are arranged opposite each other in the first direction X, and the second housing 512 is installed on the first housing 511. The electrical control box 510 also includes two fourth housings 514 arranged opposite each other in the second direction Y. The first housing 511, the second housing 512, the third housing 513, the two fourth housings 514, and the second plate 230 together enclose an electrical control cavity for accommodating the electrical control module.

[0141] like Figure 21 and Figure 22 As shown, the second plate 230 includes a third flange 232, which extends along the first direction X. The third housing 513 includes a fourth flange 5131. In the third direction Z, the fourth flange 5131 is located on the side of the third flange 232 away from the first plate 210, and the fourth flange 5131 is in contact with the third flange 232. Thus, when the partition plate 200 is not fixedly installed with the top cover assembly 100, the sealing side plate 701, or the electrical control box assembly 500, the fourth flange 5131 can act on the third flange 232 to prevent the partition plate 200 from tilting. During disassembly and maintenance, the fourth flange 5131 can also be used to support the partition plate 200, further increasing the area that the partition plate 200 can support and preventing the partition plate 200 from falling.
