Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to a ducted air conditioner. Background Technology

[0002] Ducted air conditioners are a type of split-system air conditioner, consisting of an indoor unit and an outdoor unit connected by refrigerant piping to form a refrigerant circulation loop. The indoor unit of a ducted air conditioner is installed in the space between the ceiling or walls, and it blows cool or warm air directly into each room through a duct system, thus not occupying interior space. Due to its concealed installation, minimal impact on the aesthetics of the room, and advantages such as simple structure and easy maintenance, it is widely used.

[0003] A typical duct system includes a support component and a volute. The support component is installed in the space between the ceiling or wall, and the volute is mounted on the support component to house the fan, thereby outputting cold or hot air through the air outlet on the support component.

[0004] However, the existing duct system is not convenient for maintenance personnel to repair or replace the fan components inside the casing. Therefore, how to design a duct system to facilitate maintenance personnel in repairing or replacing fan components is a technical problem that needs to be solved. Utility Model Content

[0005] This utility model discloses a ducted air conditioner, which allows the volute and support components to be slidably and detachably connected, making it easy to repair or replace the fan components inside the volute.

[0006] To achieve the above objectives, in a first aspect, this utility model discloses a ducted air conditioner, comprising:

[0007] Indoor unit;

[0008] The indoor unit includes:

[0009] Indoor heat exchanger;

[0010] A volute is provided on one side of the indoor heat exchanger, and a first air outlet is provided on the volute;

[0011] A fan assembly, wherein at least part of the fan assembly is disposed within the volute;

[0012] A support component is provided with an air inlet and a second air outlet connected to the air inlet. The volute is slidably and detachably connected to the support component, and the air inlet is connected to the first air outlet.

[0013] The ducted air conditioner of this application allows the volute and the support component to be slidably and detachably connected. When the fan assembly inside the volute needs to be repaired or replaced, the volute can be detached from the support component by sliding relative to it. This facilitates maintenance personnel in repairing or replacing the fan assembly inside the volute. At the same time, the volute component and the support component can be detached into two separate parts, which can be transported and installed separately, thus facilitating transportation and installation by transportation personnel.

[0014] As an optional implementation, the support component is provided with a first engaging portion, and the volute is provided with a second engaging portion. The first engaging portion is slidably and detachably connected to the second engaging portion. One of the first engaging portion and the second engaging portion is a protrusion, and the other is a sliding space.

[0015] By setting the first engaging part and the second engaging part, the volute and the support component can be slidably engaged. By sliding the protrusion into the sliding space, the volute and the support component can be connected. The sliding space can also limit the protrusion in the direction perpendicular to the sliding direction. By sliding the protrusion out of the sliding space, the volute can be disassembled relative to the support component.

[0016] As an optional implementation, the support component has a mounting surface with an air inlet; the first engaging portion is the sliding space; a connector is provided on the mounting surface, the connector being disposed around the air inlet, the connector including a first connecting plate and a second connecting plate, the first connecting plate protruding from the mounting surface along a first direction, the second connecting plate being connected to the side of the first connecting plate opposite to the mounting surface, an extension plate being provided around the air inlet, the extension plate being spaced apart from the second connecting plate in the first direction to form the first engaging portion; the second engaging portion protruding from the side wall of the volute; the first direction is perpendicular to the mounting surface.

[0017] By setting up a connector and an extension plate, with the second connecting plate and the extension plate spaced apart in the first direction, a sliding space can be formed between them. This allows the protrusion of the volute to slide within the sliding space. When the protrusion slides out of the second connecting plate and the extension plate, the volute can be detached from the support component. Furthermore, by creating the sliding space using the connector and extension plate, the connector and extension plate do not need to be correspondingly positioned in the first direction. Compared to forming a complete slide rail on the support component, this reduces the weight of the support component, thus facilitating the lightweight design of the ducted air conditioner.

[0018] As an optional implementation, both the first engaging portion and the second engaging portion extend along the second direction; the dimension of the second connecting plate in the second direction is L, satisfying: L≥1mm, and / or, L≤4mm; the second direction is parallel to the mounting surface.

[0019] By ensuring L ≥ 1mm, the second connecting plate has a certain dimension in the second direction, which provides sufficient structural strength and extends its service life. It also ensures a certain contact area between the second connecting plate and the second engaging part, resulting in smoother sliding. By ensuring L ≤ 4mm, the second connecting plate's dimension in the second direction is prevented from becoming excessively large, avoiding excessive friction between the second connecting plate and the second engaging part that would make disassembly from the support component difficult. This also helps reduce the weight of the second connecting plate, thus facilitating the lightweight design of the ducted air conditioner.

[0020] As an optional implementation, the second engaging portion has a dimension D1 in the second direction, the first engaging portion has a dimension D2 in the second direction, and the length L satisfies: D2-D1≥0.5mm, and / or, D2-D1≤1.5mm.

[0021] By ensuring that D2-D1 ≥ 0.5 mm, the first engaging portion is relatively larger than the second engaging portion in the second direction, and there is a certain dimensional difference between them. This allows for sufficient space in the first engaging portion in the second direction when the second engaging portion engages with it, facilitating the engagement of the second engaging portion and thus the assembly of the volute and the support component. By ensuring that D2-D1 ≤ 1.5 mm, the first engaging portion is relatively larger than the second engaging portion in the second direction, but the dimensional difference is not too large. This prevents the first engaging portion from having excessively large space in the second direction, which could lead to the second engaging portion easily detaching from the first engaging portion. This ensures a relatively tight sliding fit between the first and second engaging portions.

[0022] As an optional implementation, the second connecting plate includes a first main body and a flanged portion, the flanged portion being connected to the first main body and bent relative to the first main body in a direction away from the supporting member.

[0023] By setting a first main body and a flange, when the second engaging part slides into the first engaging part, the flange is bent away from the support member relative to the first main body. That is, the distance between the flange and the mounting surface of the support member in the first direction is greater than the distance between the first main body and the mounting surface in the first direction. This can help avoid the second engaging part. Furthermore, the side of the flange facing the support member will form an inclined surface at an angle to the mounting surface, which can guide the movement of the second engaging part and facilitate the second engaging part sliding into the first engaging part.

[0024] As an optional implementation, the extension plate includes a second main body and a bent portion. The bent portion is connected to one end of the second main body in a second direction, and the bent portion bends inward toward the support member relative to the second main body to avoid the second engaging portion; the second direction is parallel to the mounting surface.

[0025] By setting a second main body and a bending part, when the second engaging part slides into the first engaging part, the bending part bends inward relative to the second main body towards the support member. That is, the flange and the mounting surface of the support member are a certain distance apart in the first direction, which can avoid the second engaging part and facilitate the second engaging part to slide into the first engaging part.

[0026] As an optional implementation, the support component is provided with a first limiting member, which is located on one side of the air inlet in the second direction, and the first limiting member is used to limit the position of the volute in the second direction;

[0027] The support component is provided with an mounting component and a second limiting component. The mounting component is located on the other side of the air inlet in the second direction. The second limiting component is detachably connected to the mounting component and is used to limit the position of the volute in the second direction.

[0028] By providing a first limiting part, the volute can be blocked, thereby restricting its position in the second direction and preventing it from detaching from the mounting plate. Simultaneously, the first limiting part also serves to position the volute on the mounting plate. After the second engaging part of the volute slides into the first engaging part until the volute abuts against the first limiting part, it indicates that the volute is properly installed. By providing a mounting component and a second limiting part, when the second limiting part is connected to the mounting component, the second and first limiting parts together restrict the volute's position in the second direction, further preventing it from detaching from the mounting plate. After the second limiting part is removed from the mounting component, the volute can move in the direction away from the first limiting part, thereby removing the volute from the mounting plate.

[0029] As an optional implementation, the support component includes a mounting plate, a first side plate, a second side plate, and a third side plate. The mounting plate is provided with an air inlet. The volute is slidably and detachably connected to the mounting plate. The first side plate, the second side plate, and the third side plate are connected in sequence and are all connected to the mounting plate to enclose and form an air outlet cavity. The air outlet cavity has two adjacent second air outlets.

[0030] The first, second, and third side plates are used for mounting on a target mounting surface (e.g., the bottom surface of a ceiling, or the bottom surface of an additional mounting bracket on the ceiling) and jointly support the mounting plate. Simultaneously, the first, second, and third side plates enclose an air cavity, which has two adjacent second air outlets. Specifically, one air outlet is formed between the first, second, and third side plates, and another is formed between the first side plate, the mounting plate, and the third side plate. Heat exchange air flowing in from the air inlet of the mounting plate can be exhausted through the two second air outlets, thus achieving bidirectional airflow for the ducted air conditioner (the target mounting surface is usually parallel to a horizontal plane, thus enabling both horizontal and vertical airflow).

[0031] As an optional implementation, the angle between the mounting plate and the target mounting surface is α, satisfying: α ≥ 35°, and / or α ≤ 40°.

[0032] This makes the air volume of the heat exchange air discharged from the second air outlet formed between the first side plate, the second side plate and the third side plate relatively close to the air volume of the heat exchange air discharged from the second air outlet formed between the first side plate, the mounting plate and the third side plate, that is, makes the air volume of the horizontal air outlet and the vertical air outlet relatively close.

[0033] Compared with the prior art, the beneficial effects of this application are:

[0034] The ducted air conditioner provided in this application embodiment allows the volute and the support component to be slidably and detachably connected. When the fan assembly inside the volute needs to be repaired or replaced, the volute can be detached from the support component by sliding the volute relative to the support component. This facilitates maintenance personnel in repairing or replacing the fan assembly inside the volute. At the same time, the volute component and the support component can be detached into two separate parts, which can be transported and installed separately, thereby facilitating transportation and installation by transportation personnel.

[0057] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0058] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0059] Please refer to the following: Figure 1 and Figure 2 The first aspect of this application discloses a ducted air conditioner, which includes an indoor unit 1 and an outdoor unit (not shown). The ducted air conditioner can be installed on a roof, ceiling, or wall.

[0060] Indoor unit 1 and outdoor unit 1 can be set up as one unit. That is, indoor unit 1 of a ducted air conditioner refers to the part of the ducted air conditioner located indoors, and outdoor unit refers to the part of the ducted air conditioner located outdoors.

[0061] Specifically, the indoor unit 1 includes an indoor heat exchanger 10, a volute 11, and a fan assembly 12. The indoor heat exchanger 10 is used to exchange heat with indoor air. The indoor heat exchanger 10 is located on the leeward side of the fan assembly 12. The volute 11 is provided with a first air outlet 110. The fan assembly 12 is at least partially located inside the volute 11.

[0062] Driven by the fan assembly 12, the indoor air, after exchanging heat with the indoor heat exchanger 10, can flow out the heat exchange air from the first air outlet 110 of the volute 11.

[0063] In some embodiments, the indoor unit 1 also includes an indoor unit housing 14, in which the indoor heat exchanger 10, the volute 11, and the fan assembly 12 are all disposed.

[0064] Please refer to the following: Figure 3 and Figure 4 In some embodiments, the fan assembly 12 includes a drive motor 120 and a heat exchange fan 121. The heat exchange fan 121 is disposed inside the volute 11, and the drive motor 120 is disposed in the volute 11. The drive motor 120 is used to provide power to the heat exchange fan 121.

[0065] In some embodiments, the outdoor unit includes an outdoor unit housing, an outdoor heat exchanger, and an outdoor fan. The outdoor unit housing has an outdoor receiving space, where the outdoor fan and outdoor heat exchanger are located. In this embodiment, the indoor unit housing 14 and the outdoor unit housing can be integrally formed.

[0066] In some embodiments, the outdoor unit casing is provided with an outdoor air inlet and an outdoor air outlet, both of which are connected to the outdoor housing space. The outdoor air inlet is used to introduce outdoor air into the outdoor housing space, and the outdoor air outlet is used to exhaust air from the outdoor housing space to the outside. The rotation of the outdoor fan causes outdoor air to enter the outdoor housing space through the outdoor air inlet and exchange heat with the outdoor heat exchanger. The heat-exchanged outdoor air then flows out of the outdoor housing space through the outdoor air outlet.

[0067] In some embodiments, the outdoor unit also includes a compressor and a throttling device, both located within the outdoor containment space. A ducted air conditioner performs a refrigeration cycle using a compressor, condenser, throttling device, and evaporator. The refrigeration cycle involves a series of processes involving compression, condensation, expansion, and evaporation, supplying refrigerant to conditioned and heat-exchanged air. The compressor compresses the refrigerant gas at a low temperature and low pressure, discharging it at a high temperature and high pressure; the discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, releasing heat to the surrounding environment through the condensation process. The throttling device expands the high-temperature, high-pressure liquid refrigerant condensed in the condenser into a low-pressure liquid refrigerant phase. The evaporator evaporates the refrigerant expanded in the throttling device, returning the low-temperature, low-pressure refrigerant gas to the compressor. The evaporator achieves a cooling effect by utilizing the latent heat of refrigerant evaporation to exchange heat with the material being cooled. Throughout the cycle, the ducted air conditioner regulates the temperature of the indoor space.

[0068] In some embodiments, one of the indoor heat exchanger 10 and the outdoor heat exchanger is a condenser and the other is an evaporator. When the indoor heat exchanger 10 is used as a condenser, the ducted air conditioner is used as a heater in heating mode. When the indoor heat exchanger 10 is used as an evaporator, the ducted air conditioner is used as a cooler in cooling mode.

[0069] Please refer to the following: Figures 5 to 9 In some embodiments, the indoor unit further includes a support component 13. The indoor unit 1 includes an indoor heat exchanger 10, a volute 11, a fan assembly 12, and a support component 13. The volute 11 is disposed on one side of the heat exchanger and has a first air outlet 110. The fan assembly 12 is at least partially disposed inside the volute 11. The support component 13 has an air inlet 130 and a second air outlet 135 connected to the air inlet 130. The volute 11 is slidably and detachably connected to the support component 13, and the air inlet 130 is connected to the first air outlet 110.

[0070] The ducted air conditioner of this application allows the volute 11 and the support component 13 to be slidably and detachably connected. When the fan assembly 12 inside the volute 11 needs to be repaired or replaced, the volute 11 can be detached from the support component 13 by sliding the volute 11 relative to the support component 13. This facilitates maintenance personnel to repair or replace the fan assembly 12 inside the volute 11. At the same time, the volute 11 and the support component 13 can be detached into two separate parts, which can be transported and installed separately, thereby facilitating transportation and installation by transportation personnel.

[0071] Optionally, the support component 13 may be a shell structure or a box structure, etc., and the specific choice can be made according to the actual situation. In this embodiment, no specific limitation is made.

[0072] In some embodiments, the support component 13 includes a mounting plate 13a, a first side plate 13b, a second side plate 13c, and a third side plate 13d. The mounting plate 13a is provided with an air inlet 130. The volute 11 is slidably and detachably connected to the mounting plate 13a. The first side plate 13b, the second side plate 13c, and the third side plate 13d are connected in sequence and are all connected to the mounting plate 13a to enclose and form an air outlet cavity 136. The air outlet cavity 136 has two adjacent second air outlets 135.

[0073] The first side plate 13b, the second side plate 13c, and the third side plate 13d are used to install on a target mounting surface (e.g., the surface of a ceiling, the surface of an additional mounting bracket on the ceiling, or the surface of the casing of a ducted air conditioner) and to jointly support the mounting plate 13a. Simultaneously, the first side plate 13b, the second side plate 13c, and the third side plate 13d enclose an air cavity 136, which has two adjacent second air outlets 135. Specifically, one second air outlet 135 is formed between the first side plate 13b, the second side plate 13c, and the third side plate 13d, and another second air outlet 135 is formed between the first side plate 13b, the mounting plate 13a, and the third side plate 13d. Heat exchange air flowing in from the air inlet 130 of the mounting plate 13a can be discharged from the two second air outlets 135, thereby achieving bidirectional airflow for the ducted air conditioner (the target mounting surface is usually parallel to the horizontal plane, thus enabling both horizontal and vertical airflow).

[0074] In addition, the ducted air conditioner can achieve independent horizontal or vertical airflow by closing one of the second air outlets 135.

[0075] In other embodiments, the support member 13 may also include a fourth side plate (not shown), the first side plate 13b, the second side plate 13c, the third side plate 13d and the fourth side plate are connected in sequence and are all connected to the mounting plate 13a to enclose and form an air outlet cavity 136, the air outlet cavity 136 having a second air outlet 135.

[0076] In some embodiments, a fixing plate 13e is provided on the side of the first side plate 13b, the second side plate 13c, and the third side plate 13d facing away from the mounting plate 13a. The fixing plate 13e is used to install on the target mounting surface. By providing the fixing plate 13e, it is easy to fix the first side plate 13b, the second side plate 13c, and the third side plate 13d to the target mounting surface.

[0077] In some embodiments, the support member 13 is provided with a first engaging portion 132, and the volute 11 is provided with a second engaging portion 111. The first engaging portion 132 is slidably and detachably connected to the second engaging portion 111. One of the first engaging portion 132 and the second engaging portion 111 is a protrusion, and the other is a sliding space. That is, the first engaging portion 132 may be a protrusion, and the second engaging portion 111 may be a sliding space, or the first engaging portion 132 may be a sliding space, and the second engaging portion 111 may be a protrusion. In this embodiment, the mounting plate 13a is provided with the first engaging portion 132.

[0078] By setting the first engaging part 132 and the second engaging part 111, the volute 11 and the support member 13 can be slidably engaged. By sliding the protrusion into the sliding space, the volute 11 and the support member 13 can be connected. The sliding space can also limit the protrusion in the direction perpendicular to the sliding direction. By sliding the protrusion out of the sliding space, the volute 11 can be disassembled relative to the support member 13.

[0079] Understandably, the sliding space can be a groove, or the space between two parallel plates, and so on.

[0080] Optionally, the protrusion can be a block protrusion, a plate protrusion, or a cylindrical protrusion, etc., and the specific type can be selected according to the situation. In this embodiment, no specific limitation is made.

[0081] In some embodiments, the support member 13 has a mounting surface 131 on which an air inlet 130 is provided. In this embodiment, the mounting plate 13a of the support member 13 has a mounting surface 131, which is used to support the volute 11.

[0082] In some embodiments, the first engaging portion 132 is a sliding space, and a connector 133 is provided on the mounting surface 131. The connector 133 is located on the periphery of the air inlet 130, such as... Figure 10 As shown, the connector 133 includes a first connecting plate 133a and a second connecting plate 133b. The first connecting plate 133a protrudes from the mounting surface 131 along the first direction X. The second connecting plate 133b is connected to the side of the first connecting plate 133a away from the mounting surface 131. An extension plate 134 protrudes from the periphery of the air inlet 130. The extension plate 134 and the second connecting plate 133b are spaced apart in the first direction X to form a first engaging portion 132. The second engaging portion 111 protrudes from the side wall of the volute 11.

[0083] It is understandable that the first direction X is perpendicular to the mounting surface 131.

[0084] By setting the connector 133 and the extension plate 134, the second connecting plate 133b of the connector 133 and the extension plate 134 are spaced apart in the first direction X, and a sliding space can be formed between the second connecting plate 133b and the extension plate 134. This allows the protrusion of the volute 11 to slide within the sliding space. When the protrusion slides out of the second connecting plate 133b and the extension plate 134, the volute 11 can be detached from the support member 13. In addition, by setting the connector 133 and the extension plate 134 to form the sliding space, the connector 133 and the extension plate 134 do not need to be correspondingly set in the first direction X. Compared with forming a complete slide rail on the support member 13, this helps to reduce the weight of the support member 13, thereby facilitating the lightweight design of the ducted air conditioner.

[0085] Optionally, the number of connectors 133 and the number of extension plates 134 can be one or more, depending on the situation, and are not specifically limited in this embodiment. The number of first engaging portions 132 formed between the connectors 133 and the extension plates 134 can also be one or more. For example, there can be two connectors 133 and one extension plate 134, with the two connectors 133 and one extension plate 134 forming one first engaging portion 132. Alternatively, there can be two connectors 133 and two extension plates 134, with the two connectors 133 forming two first engaging portions 132 with the two extension plates 134 respectively, and so on.

[0086] Optionally, the number of second engaging parts 111 may be one or more, which can be selected according to the situation, and is not specifically limited in this embodiment.

[0087] For example, the number of connectors 133 can be four, the number of extension plates 134 and second engaging parts 111 can be two, the air inlet 130 is provided with two connectors 133 and one extension plate 134 on both sides in the third direction Z to form two first engaging parts 132, and the volute 11 is provided with a second engaging part 111 on each of the two side walls in the third direction Z.

[0088] It is understandable that the third party is parallel to the mounting surface 131 in the Z direction.

[0089] Optionally, the support component 13 and the connector 133 can be separate components, that is, the support component 13 and the connector 133 are two separate components. Alternatively, the support component 13 and the connector 133 can be integrally formed, that is, the support component 13 and the connector 133 are one component. For example, the support component 13 can be a sheet metal part, and the support component 13 and the connector 133 can be obtained by cutting, bending or other processing methods on the sheet metal part. The specific choice can be made according to the situation, and no specific limitation is made in this embodiment.

[0090] In some embodiments, the support member 13 is provided with a first limiting member 137, which is located on one side of the air inlet 130 in the second direction Y. The first limiting member 137 is used to limit the position of the volute 11 in the second direction Y.

[0091] Since the mounting plate 13a is inclined relative to the target mounting surface, the volute 11 may slip off the mounting surface 131. By providing the first limiting part, the volute 11 can be blocked, thereby limiting the position of the volute 11 in the second direction Y and preventing the volute 11 from detaching from the mounting plate 13a. At the same time, the first limiting member 137 can also play a positioning role when the volute 11 is installed on the mounting plate 13a. After the second engaging part 111 of the volute 11 is slid into the first engaging part 132, until the volute 11 abuts against the first limiting part, it means that the volute 11 has been installed in place.

[0092] Optionally, the first limiting member 137 may be a plate-like structure or a block-like structure, etc., and the specific choice can be made according to the actual situation. In this embodiment, no specific limitation is made.

[0093] Optionally, the first limiting member 137 and the mounting plate 13a can be integrally formed or separately formed, depending on the actual situation. In this embodiment, no specific limitation is made.

[0094] In some embodiments, the support member 13 is provided with a mounting member 138 and a second limiting member 139. The mounting member 138 is located on the other side of the air inlet 130 in the second direction Y. The second limiting member 139 is detachably connected to the mounting member 138 and is used to limit the position of the volute 11 in the second direction Y.

[0095] By setting the mounting member 138 and the second limiting member 139, when the second limiting member 139 is connected to the mounting member 138, the second limiting member 139 and the first limiting member 137 can jointly restrict the position of the volute 11 in the second direction Y, better preventing the volute 11 from detaching from the mounting plate 13a. After the second limiting member 139 is removed from the mounting member 138, the volute 11 can move in the direction away from the first limiting member 137, thereby removing the volute 11 from the mounting plate 13a.

[0096] Optionally, the mounting component 138 may be a plate-like structure or a block-like structure, etc., and the specific choice can be made according to the actual situation. In this embodiment, no specific limitation is made.

[0097] Optionally, the second limiting member 139 may be a plate-like structure or a block-like structure, etc., and the specific choice can be made according to the actual situation. In this embodiment, no specific limitation is made.

[0098] In some embodiments, the second connecting plate 133b includes a first main body portion 1330 and a flange portion 1331, the flange portion 1331 being connected to the first main body portion 1330, and the flange portion 1331 being bent relative to the first main body portion 1330 in a direction away from the support member 13.

[0099] By providing a first main body 1330 and a flange 1331, when the second engaging part 111 slides into the first engaging part 132, the flange 1331 is bent away from the support member 13 relative to the first main body 1330. That is, the distance between the flange 1331 and the mounting surface 131 of the support member 13 in the first direction X is greater than the distance between the first main body 1330 and the mounting surface 131 in the first direction X. This can help avoid the second engaging part 111. Furthermore, the side of the flange 1331 facing the support member 13 will form an inclined surface that forms an angle with the mounting surface 131, which can guide the movement of the second engaging part 111 and facilitate the second engaging part 111 sliding into the first engaging part 132.

[0100] The second connecting plate 133b can be a sheet metal part. The first main body 1330 and the flanged part 1331 are obtained by bending the sheet metal part. The specific selection can be made according to the situation, and no specific limitation is made in this embodiment.

[0101] In some embodiments, the extension plate 134 includes a second main body portion 1340 and a bent portion 1341. The bent portion 1341 is connected to one end of the second main body portion 1340 in the second direction Y, and the bent portion 1341 is bent toward the interior of the support member 13 relative to the second main body portion 1340 to avoid the second engaging portion 111.

[0102] It is understandable that the second direction Y is parallel to the mounting surface 131 and perpendicular to the third direction Z.

[0103] By providing a second main body 1340 and a bent portion 1341, when the second engaging portion 111 slides into the first engaging portion 132, the bent portion 1341 bends relative to the second main body 1340 toward the inside of the support member 13. That is, the flange portion 1331 and the mounting surface 131 of the support member 13 are a certain distance apart in the first direction X, which can avoid the second engaging portion 111 and facilitate the second engaging portion 111 sliding into the first engaging portion 132.

[0104] Please see Figures 11 to 13 In some embodiments, the first engaging portion 132 and the second engaging portion 111 both extend along the second direction Y, and the second connecting plate 133b has a dimension L in the second direction Y, satisfying: L≥1mm, and / or, L≤4mm.

[0105] It is understandable that the second direction Y is parallel to the mounting surface 131, that is, the first direction X and the second direction Y are perpendicular to each other.

[0106] In one example, the following condition is met: L ≥ 1 mm. For example, L can be 1 mm, 2 mm, 3 mm, 4 mm, or 5 mm, etc.

[0107] The second connecting plate 133b has a certain size in the second direction Y, which enables the second connecting plate 133b to have sufficient structural strength and improve its service life. At the same time, it also enables the second connecting plate 133b and the second engaging part 111 to have a certain contact area, so that the sliding between the second connecting plate 133b and the second engaging part 111 is relatively smooth.

[0108] In another example, the condition L ≤ 4 mm is met. For example, L can be 0.5 mm, 1 mm, 2 mm, 3 mm, or 4 mm, etc.

[0109] This ensures that the size of the second connecting plate 133b in the second direction Y is not too large, which can prevent excessive friction between the second connecting plate 133b and the second engaging part 111 from making it difficult to disassemble from the support member 13. At the same time, it also helps to reduce the weight of the second connecting plate 133b, thereby facilitating the lightweight design of the ducted air conditioner.

[0110] In another example, the following condition is met: 1mm ≤ L ≤ 4mm. For example, L can be 1mm, 2mm, 3mm, or 4mm, etc.

[0111] On the one hand, having a certain size in the second direction Y ensures that the second connecting plate 133b has sufficient structural strength, improving its service life. It also allows for a certain contact area between the second connecting plate 133b and the second engaging portion 111, resulting in smoother sliding between them. On the other hand, ensuring that the size of the second connecting plate 133b in the second direction Y is not excessive prevents excessive friction between it and the second engaging portion 111, which could make disassembly from the support component 13 difficult. This also helps reduce the weight of the second connecting plate 133b, thus facilitating the lightweight design of the ducted air conditioner.

[0112] Optionally, the dimensions of the second connecting plate 133b and the first connecting plate 133a in the second direction Y may be the same or different. The specific selection can be made according to the actual situation, and no specific limitation is made in this embodiment.

[0113] In some embodiments, the angle between the mounting plate 13a and the target mounting surface is α, satisfying: α ≥ 35°, and / or α ≤ 40°.

[0114] In one example, the following condition is satisfied: a ≥ 35°. For example, a can be 35°, 37.5°, 40°, or 45°, etc.

[0115] This ensures that the mounting plate 13a is tilted relative to the target mounting surface to prevent the air volume of the heat exchange air discharged from the second air outlet 135 formed between the first side plate 13b, the mounting plate 13a and the third side plate 13d from being much lower than the air volume of the heat exchange air discharged from the second air outlet 135 formed between the first side plate 13b, the second side plate 13c and the third side plate 13d.

[0116] In another example, the following condition is satisfied: a ≤ 40°. For example, a can be 30°, 35°, 37.5°, or 40°, etc.

[0117] This ensures that the tilt of the mounting plate 13a relative to the target mounting surface is not too large, preventing the air volume of the heat exchange air discharged from the second air outlet 135 formed between the first side plate 13b, the second side plate 13c, and the third side plate 13d from being far lower than the air volume of the heat exchange air discharged from the second air outlet 135 formed between the first side plate 13b, the mounting plate 13a, and the third side plate 13d.

[0118] In another example, the following condition is satisfied: 35°≤a≤40°. For example, a can be 35°, 37.5°, or 40°, etc.

[0119] The air volume of the heat exchange air discharged from the second air outlet 135 formed between the first side plate 13b, the second side plate 13c and the third side plate 13d is relatively close to that of the heat exchange air discharged from the second air outlet 135 formed between the first side plate 13b, the mounting plate 13a and the third side plate 13d, that is, the air volume of the horizontal air outlet and the vertical air outlet are relatively close.

[0120] Please refer to the following: Figure 13 and Figure 14 In some embodiments, the second engaging portion 111 has a dimension D1 in the second direction Y, and the first connecting plate 133a has a dimension D2 in the second direction Y. The length L satisfies: D2-D1≥0.5mm, and / or, D2-D1≤1.5mm. The dimension of the first engaging portion 132 in the second direction Y is the same as the dimension of the first engaging portion 132 in the second direction Y.

[0121] In one example, the following condition is satisfied: D2 - D1 ≥ 0.5 mm. For example, D2 can be 1.5 mm and D1 can be 1 mm, or D2 can be 2 mm and D1 can be 1.5 mm, or D2 can be 2 mm and D1 can be 1 mm, and so on.

[0122] The first engaging portion 132 is larger in size than the second engaging portion 111 in the second direction Y, and there is a certain size difference between the two. This makes the first engaging portion 132 have a certain amount of extra space in the second direction Y when the second engaging portion 111 engages with the first engaging portion 132. This is beneficial for engaging the second engaging portion 111 with the first engaging portion 132, thereby facilitating the assembly of the volute 11 and the support member 13.

[0123] In another example, the following condition is satisfied: D2-D1≤1.5mm. For example, D2 can be 3mm and D1 can be 1.5mm, or D2 can be 3.5mm and D1 can be 2mm, or D2 can be 2mm and D1 can be 1mm, and so on.

[0124] The size of the first engaging portion 132 is larger than that of the second engaging portion 111 in the second direction Y, and the size difference between the two is not too large. This prevents the first engaging portion 132 from having too much extra space in the second direction Y when the second engaging portion 111 engages with the first engaging portion 132, which would make it easy for the second engaging portion 111 to detach from the first engaging portion 132. This helps to make the sliding fit between the first engaging portion 132 and the second engaging portion 111 relatively tight.

[0125] In another example, the following condition is satisfied: 0.5mm ≤ D2 - D1 ≤ 1.5mm. For example, D2 can be 1.5mm and D1 can be 1mm, or D2 can be 2mm and D1 can be 1.5mm, or D2 can be 2mm and D1 can be 1mm, or D2 can be 2.5mm and D1 can be 1.5mm, D2 can be 3mm and D1 can be 1.5mm, or D2 can be 3.5mm and D1 can be 2mm, and so on.

[0126] On the one hand, the first engaging portion 132 is larger in size than the second engaging portion 111 in the second direction Y, and there is a certain size difference between them. This ensures that when the second engaging portion 111 engages with the first engaging portion 132, the first engaging portion 132 has a certain amount of extra space in the second direction Y, which is beneficial for engaging the second engaging portion 111 into the first engaging portion 132, thereby facilitating the assembly of the volute 11 and the support member 13. On the other hand, the first engaging portion 132 is larger in size than the second engaging portion 111 in the second direction Y, and the size difference between them is not too large. This prevents the first engaging portion 132 from having excessively large extra space in the second direction Y, which could easily cause the second engaging portion 111 to detach from the first engaging portion 132. This ensures a relatively tight sliding fit between the first engaging portion 132 and the second engaging portion 111.
