Description

Technical Field

[0001] The utility model relates to the technical field of air conditioning, in particular to an air conditioner. Background Art

[0002] An air conditioner is a device commonly used for indoor cooling or heating. An air conditioner usually includes a casing, an evaporator assembly and an air duct assembly arranged in the casing. The casing is provided with an air outlet, and an air outlet frame assembly is also provided at the air outlet. The gas exchanged with heat by the evaporator assembly can be blown out from the air outlet under the action of the air duct assembly to achieve indoor cooling or heating effects. The air outlet frame assembly can be used to adjust the air outlet direction to improve the user's comfort. In order to ensure the cleanliness of the air conditioner during use, the air duct assembly that is prone to dust accumulation needs to be removed from the casing for replacement and cleaning.

[0003] The air duct components and air outlet frame components of the air conditioner in the related art are usually installed in layers, and when disassembling, the components also need to be disassembled from the outside to the inside in order. For example, when cleaning and maintaining the air duct component, the housing must be disassembled first, then the air outlet frame component, and then the air duct component must be removed before cleaning the air duct component. Therefore, the operation of cleaning and maintaining the air duct component of the air conditioner in the related art is cumbersome, which seriously affects the maintenance efficiency. Utility Model Content

[0004] The problem that the utility model solves is how to improve the operability and efficiency of the air duct assembly during cleaning and maintenance; and when cleaning and maintaining the air duct assembly, the air duct assembly can be lifted up and cleaned directly next to the second shell, without the need to completely disassemble the air duct assembly from the second shell, thereby improving the problem that it is difficult to completely disassemble the air duct assembly from the second shell and the cleaning is troublesome. At the same time, it can also improve the problem that the air duct assembly is difficult to reinstall after being completely disassembled from the second shell.

[0005] In order to solve the above problems, the utility model provides an air conditioner, comprising:

[0006] A casing, the casing comprising a first shell and a second shell, the first shell and the second shell are detachably or movably connected to enclose and form an inner cavity of the casing, and the first shell is configured to open or close the inner cavity of the casing;

[0007] An air outlet frame assembly, which is connected to the first housing and is used to adjust the air outlet direction; and

[0008] The air duct assembly is rotatably connected to the second shell; wherein, when the first shell opens the inner cavity of the casing, the air outlet frame assembly is removed or moved relative to the second shell synchronously with the first shell, and the air duct assembly can rotate in the vertical direction relative to the second shell and extend out of the second shell.

[0009] When the air duct assembly of the air conditioner of the present application needs to be cleaned or maintained, the first shell can be used to open the inner cavity of the casing, and then the air duct assembly can be rotated and extended out of the second shell to facilitate the cleaning and maintenance of the air duct assembly; wherein, when the first shell is used to open the inner cavity of the casing, the air outlet frame assembly connected to the first shell can be removed or moved relative to the second shell synchronously with the first shell, and thus there is no need for additional and separate disassembly of the air outlet frame assembly. Therefore, the disassembly process when cleaning and maintaining the air duct assembly can be reduced, which is conducive to improving the ease of cleaning and maintenance of the air duct assembly.

[0010] Since the air duct assembly is rotatably connected to the second shell, it is not necessary to completely remove the air duct assembly from the second shell when cleaning and maintaining the air duct assembly. Therefore, the air duct assembly can be cleaned and maintained directly next to the second shell, thereby improving the problem that it is difficult to completely remove the air duct assembly from the second shell and the cleaning is troublesome. At the same time, the air duct assembly can also be rotated to reinstall it into the second shell, thereby improving the problem that the air duct assembly is difficult to reinstall after being completely removed from the second shell.

[0011] In an optional embodiment, the casing also includes a third shell, which is snap-fitted and connected to the second shell, and the third shell is distributed below the first shell. When the air duct assembly is rotated to extend out of the second shell, the third shell can support the air duct assembly to keep the air duct assembly in a horizontal or inclined state.

[0012] By using the third shell to lift the air duct assembly that is rotated out of the second shell, the air duct assembly can be relatively stably suspended in the air, thereby facilitating cleaning and maintenance of the air duct assembly, reducing the need for personnel who change and clean the air duct assembly to bend or squat, and reducing labor intensity.

[0013] In an optional embodiment, the air conditioner further includes a rotating bracket, and the air duct assembly is rotatably connected to the second shell via the rotating bracket.

[0014] The air duct assembly is rotatably connected to the second shell by rotating the bracket, which ensures the operability of rotatably assembling the air duct assembly to the second shell on the one hand, and reduces the difficulty of designing and demoulding the second shell on the other hand.

[0015] In an optional embodiment, the rotating bracket is provided with a supporting portion, and the air duct assembly is provided with an abutting portion; when the air duct assembly is rotated to extend out of the second shell, the supporting portion can abut against the abutting portion to hold up the air duct assembly.

[0016] By using the supporting part and the supporting part to support the air duct assembly, the air duct assembly can be lifted up so that the air duct assembly can be relatively stably suspended in the air, thereby facilitating the cleaning and maintenance of the air duct assembly, reducing the bending and squatting movements of personnel who change the air duct assembly, and reducing labor intensity.

[0017] In an optional embodiment, the rotating bracket includes a first plate and a second plate connected at an angle, the first plate is connected to the second shell, and the air duct assembly is rotatably connected to the first plate, and the second plate is provided with a support portion.

[0018] The first plate and the second plate connected at an angle ensure the structural strength of the rotating bracket itself, and can prevent the rotation of the air duct assembly from being restricted or blocked by the structure of the rotating bracket, that is, it can ensure that the air duct assembly can rotate smoothly relative to the second shell.

[0019] In an optional embodiment, the rotating bracket further includes a reinforcing rib connected between the first plate and the second plate, and when the air duct assembly is rotated to extend out of the second shell, the abutting portion can also abut against the reinforcing rib to limit further rotation of the air duct assembly.

[0020] The provision of the reinforcing ribs can, on the one hand, improve the structural strength between the first plate and the second plate, and on the other hand, utilize the abutment between the abutting portion and the reinforcing ribs to prevent the air duct assembly from excessively rotating.

[0021] Moreover, the abutting portion can abut against the reinforcing ribs and the supporting portion at the same time, which can ensure the stability of the air duct assembly after it is rotated and extended out of the second shell, thereby ensuring smooth replacement and cleaning of the air duct assembly.

[0022] In an optional embodiment, the air duct assembly is provided with a limiting member; when the air duct assembly is rotated to extend out of the second shell, the limiting member can abut against the rotating bracket to limit the air duct assembly from further rotation.

[0023] The setting of the limiter can prevent the air duct assembly from excessive rotation.

[0024] The weight of the air duct assembly is relatively large. When the air duct assembly is rotated toward the outside of the second shell, the limit member and the supporting portion are easily impacted and may be damaged. In particular, when the person changing clothes accidentally fails to hold the air duct assembly steadily, the air duct assembly rotates to the outside of the second shell under the action of its own weight, causing the limit member and the supporting portion to be impacted more greatly, and more easily causing the limit member and the supporting portion to be damaged. Therefore, in an embodiment in which the air duct assembly simultaneously utilizes the limit member and the supporting portion to prevent excessive rotation of the air duct assembly, it can also avoid the problem of being unable to prevent excessive rotation of the air duct assembly when one of the limit member and the supporting portion is damaged.

[0025] In an optional embodiment, the air duct assembly includes a crossflow blade and a blade mounting seat, and both ends of the crossflow blade in the axial direction are rotatably connected to the blade mounting seat; one end of the blade mounting seat in the axial direction of the crossflow blade is rotatably connected to the second shell, and the other end of the blade mounting seat on the axis of the crossflow blade is detachably connected to the second shell.

[0026] One end of the fan blade mounting seat is rotatably connected to the second shell, which can avoid interference with the rotation of the crossflow fan blade, thereby ensuring the reliability of air outlet of the air duct assembly.

[0027] The other end of the fan blade mounting seat is configured to be detachably connected to the second housing, which can improve the stability of the air duct assembly assembled on the second housing, thereby ensuring the stability of the air outlet of the air conditioner. When the air duct assembly needs to be cleaned or replaced, the other end of the fan blade mounting seat is disassembled from the second housing, and the air duct assembly can be rotated out of the second housing, ensuring the ease of cleaning and replacement of the air duct assembly.

[0028] In an optional embodiment, the rotation axis of the crossflow blade is perpendicular to the rotation axis of the blade mounting base.

[0029] The crossflow blades are usually installed in the second shell in an upright state. By arranging the rotation axis of the crossflow blades perpendicular to the rotation axis of the blade mounting seat, the air duct assembly can be flipped in the vertical direction and extended out of the second shell when the air duct assembly is maintained.

[0030] In an optional embodiment, the crossflow blade is vertically arranged in the inner cavity of the casing, and the lower end of the blade mounting seat is rotatably connected to the second shell.

[0031] By rotatably connecting the lower end of the fan blade mounting seat to the second shell, the upper end of the air duct assembly is flipped downward when the air duct assembly is maintained. Compared with flipping the lower end of the air duct assembly upward, this flipping method is more labor-saving. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0040] The air duct components and air outlet frame components of the air conditioner in the related art are usually installed in layers, and when disassembling, the components also need to be disassembled from the outside to the inside in order. For example, when cleaning and maintaining the air duct component, the casing must be disassembled first, then the air outlet frame component must be disassembled, and then the air duct component must be removed before the air duct component can be cleaned. Therefore, the operation of cleaning and maintaining the air duct component of the air conditioner in the related art is cumbersome, which seriously affects the maintenance efficiency.

[0041] In order to improve the above-mentioned problems, the present embodiment provides an air conditioner, which can improve the operability and efficiency of cleaning and maintaining the air duct assembly; and when cleaning and maintaining the air duct assembly, the air duct assembly can be lifted up, and there is no need to completely remove the air duct assembly from the casing, thereby improving the problem that it is difficult to completely remove the air duct assembly from the casing and the cleaning is troublesome. At the same time, it can also improve the problem that the air duct assembly is difficult to reinstall after being completely removed from the casing.

[0042] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0043] Please refer to Figure 1 The air conditioner 010 of this embodiment may refer to an indoor cabinet unit, which includes a casing 100, an evaporator assembly 160, an air duct assembly 200 and an air outlet frame assembly 150. The casing 100 is provided with a casing inner cavity and an air outlet (not shown) connected to the casing inner cavity. The air duct assembly 200 and the evaporator assembly 160 are both arranged in the casing inner cavity. The air outlet frame assembly 150 is arranged in the casing 100 and is located at the air outlet. Under the action of the air duct assembly 200, the air heated by the evaporator assembly 160 can be blown out from the air outlet to achieve the effect of cooling or heating the indoor environment. The air outlet frame assembly 150 can adjust the direction of the air outlet to improve the user's comfort.

[0044] Furthermore, the housing 100 includes a first housing 110 and a second housing 120, which are detachable to enclose an inner cavity of the housing; the first housing 110 is provided with an air outlet, and the air outlet frame assembly 150 is connected to the first housing 110. The first housing 110 and the second housing 120 are configured to be detachably connected, so as to facilitate the assembly of the evaporator assembly 160 and the air duct assembly 200 in the inner cavity of the housing.

[0045] Optionally, the connection method between the first shell 110 and the second shell 120, and the connection method between the air outlet frame assembly 150 and the first shell 110 include snap-on connection, connection through fasteners such as bolts, etc., which are not specifically limited here.

[0046] It should be understood that in other embodiments, the first shell 110 may also be movably connected to the second shell 120, for example, rotatably connected or slidably connected to open the inner cavity of the shell by rotating or sliding.

[0047] It should be noted that the structures and working principles of the air outlet frame assembly 150 and the evaporator assembly 160 are similar to those in the related art and will not be described in detail here.

[0048] Please refer to Figure 1 and Figure 2In this embodiment, the air duct assembly 200 is rotatably connected to the second housing 120; wherein, when the first housing 110 opens the inner cavity of the housing, the air outlet frame assembly 150 is synchronously removed relative to the second housing 120 with the first housing 110, and the air duct assembly 200 can be rotated in the vertical direction relative to the second housing 120 and extended out of the second housing 120. When the air conditioner 010 needs to clean and maintain the air duct assembly 200, the first housing 110 can be used to open the inner cavity of the housing, and then the air duct assembly 200 can be rotated and extended out of the second housing 120, so as to facilitate the cleaning and maintenance of the air duct assembly 200; wherein, when the first housing 110 opens the inner cavity of the housing, the air outlet frame assembly 150 connected to the first housing 110 can be synchronously removed relative to the second housing 120 with the first housing 110, and then there is no need to remove the air outlet frame assembly 150 separately and separately, so that the disassembly process when cleaning and maintaining the air duct assembly 200 can be reduced, which is conducive to improving the ease of cleaning and maintenance of the air duct assembly 200. Moreover, since the air duct assembly 200 is rotatably connected to the second shell 120, it is not necessary to completely remove the air duct assembly 200 from the second shell 120 when cleaning and maintaining the air duct assembly 200. Therefore, the air duct assembly 200 can be cleaned and maintained directly next to the second shell 120, thereby improving the problem that it is difficult to completely remove the air duct assembly 200 from the second shell 120 and the cleaning is troublesome. At the same time, the air duct assembly 200 can also be rotated to be reinstalled into the second shell 120, thereby improving the problem that the air duct assembly 200 is difficult to reinstall after being completely removed from the second shell 120.

[0049] It should be noted that the air outlet and the air outlet frame assembly 150 are both arranged on the first shell 110, that is, the first shell 110 can be regarded as the front panel, and the second shell 120 can be regarded as the rear shell. The air outlet is usually configured to discharge air toward the front, that is, the air outlet usually discharges air toward the side away from the wall. After the first shell 110 and the air outlet frame assembly 150 are removed from the second shell 120, the air duct assembly 200 can be directly rotated toward the front and moved out of the second shell 120. There is no need to adjust the front and rear side placement positions of the air conditioner 010 as a whole, thereby ensuring the ease of cleaning and maintaining the air duct assembly 200.

[0050] Please refer to Figure 1 and Figure 2 The structure of the air duct assembly 200 is similar to the related art, and includes a crossflow blade 210 and a blade mounting seat 220. The two ends of the crossflow blade 210 in the axial direction are rotatably connected to the blade mounting seat 220. The crossflow blade 210 is driven to rotate by a motor so that the rotation of the crossflow blade 210 is used to blow the wind out from the air outlet.

[0051] Further, one end of the fan blade mounting seat 220 on the axial direction of the crossflow fan blade 210 is rotatably connected to the second housing 120, and the other end of the fan blade mounting seat 220 on the axis of the crossflow fan blade 210 is detachably connected to the second housing 120. Rotatingly connecting one end of the fan blade mounting seat 220 to the second housing 120 can avoid interfering with the rotation of the crossflow fan blade 210, thereby ensuring the reliability of the air outlet of the air duct assembly 200. The other end of the fan blade mounting seat 220 is configured to be detachably connected to the second housing 120, which can improve the stability of the air duct assembly 200 being assembled to the second housing 120, thereby ensuring the stability of the air outlet of the air conditioner 010. When the air duct assembly 200 needs to be cleaned or replaced, the other end of the fan blade mounting seat 220 is disassembled from the second housing 120, and the air duct assembly 200 can be rotated out of the second housing 120, ensuring the ease of cleaning and replacement of the air duct assembly 200.

[0052] Optionally, the other end of the fan blade mounting seat 220 may be detachably connected to the second housing 120 in a manner including, but not limited to, snap-fitting or connecting with fasteners such as bolts.

[0053] It should be understood that in other embodiments, the other end of the fan blade mounting seat 220 may not be configured to be detachably connected to the second housing 120, which is not specifically limited herein.

[0054] Furthermore, the rotation axis of the crossflow blade 210 is perpendicular to the rotation axis of the blade mounting seat 220. The crossflow blade 210 is usually installed in the second housing 120 in an upright state. By arranging the rotation axis of the crossflow blade 210 and the rotation axis of the blade mounting seat 220 perpendicularly, it is ensured that when the air duct assembly 200 is maintained, the air duct assembly 200 can be turned over in the vertical direction and extended out of the second housing 120.

[0055] It should be understood that in other embodiments, due to installation errors or the tilting of the air duct assembly 200 caused during the use of the air conditioner 010, the angle between the rotation axis of the crossflow blade 210 and the rotation axis of the blade mounting seat 220 can also be 89.5°, 89°, etc., which are close to vertical angles.

[0056] Please continue to refer to Figure 1 and Figure 2In order to clean and maintain the air duct assembly 200 with less effort, the crossflow blade 210 is configured to be vertically arranged in the inner cavity of the housing, that is, when the air duct assembly 200 is not removed from the second housing 120, the crossflow blade 210 is vertically arranged in the inner cavity of the housing, and the lower end of the blade mounting seat 220 is rotatably connected to the second housing 120. By rotatably connecting the lower end of the blade mounting seat 220 to the second housing 120, when maintaining the air duct assembly 200, the upper end of the air duct assembly 200 is turned downward, which is more labor-saving than turning the lower end of the air duct assembly 200 upward.

[0057] Of course, in other embodiments, the upper end of the fan blade mounting seat 220 is rotatably connected to the second shell 120. When maintaining and cleaning the air duct assembly 200, the lower end of the air duct assembly 200 can be flipped upward to allow the air duct assembly 200 to rotate and extend out of the second shell 120.

[0058] Please continue to refer to Figure 1 and Figure 2 , in order to reduce the labor intensity of cleaning and maintaining the air duct assembly 200; the housing 100 of this embodiment also includes a third housing 130, which is engaged and connected with the second housing 120, and is distributed below the first housing 110. When the air duct assembly 200 is rotated to extend out of the second housing 120, the third housing 130 can hold up the air duct assembly 200 to keep the air duct assembly 200 horizontal. By using the third housing 130 to hold up the air duct assembly 200 that is rotated out of the second housing 120, the air duct assembly 200 can be relatively stably suspended in the air, thereby facilitating the cleaning and maintenance of the air duct assembly 200, reducing the bending and squatting movements of the personnel who change and wash the air duct assembly 200, and reducing the labor intensity.

[0059] It should be understood that in other embodiments, when the air duct assembly 200 rotates to extend out of the second housing 120, the third housing 130 can hold up the air duct assembly 200 to keep the air duct assembly 200 in an inclined state, for example, the end of the air blade mounting seat 220 of the air duct assembly 200 that is not connected to the second housing 120 is tilted upward or downward. In this way, the air duct assembly 200 can also be relatively stably suspended in the air, thereby facilitating the cleaning and maintenance of the air duct assembly 200, reducing the bending and squatting movements of the personnel who change and wash the air duct assembly 200, and reducing the labor intensity.

[0060] Optionally, the connection method between the third shell 130 and the second shell 120 includes but is not limited to integral molding, snap-fitting, and connection with fasteners such as bolts.

[0061] Optionally, the housing 100 further includes a base 140, and the second housing 120 and the third housing 130 are both connected to the base 140, and the connection methods include but are not limited to plugging, snapping, and connection through fasteners such as bolts. The setting of the base 140 can ensure the stability of the air conditioner 010 when placed upright.

[0062] The manner in which the air duct assembly 200 is rotatably connected to the second housing 120 can be selected as required; Figure 3 and Figure 4 The air conditioner 010 of this embodiment further includes a rotating bracket 300, and the air duct assembly 200 is rotatably connected to the second housing 120 via the rotating bracket 300. The air duct assembly 200 is rotatably connected to the second housing 120 via the rotating bracket 300, which, on the one hand, ensures the ease of rotatably assembling the air duct assembly 200 to the second housing 120, and on the other hand, reduces the difficulty of designing and demoulding the second housing 120.

[0063] Furthermore, the air conditioner 010 further includes a rotating shaft 340, the rotating bracket 300 is connected to the middle and lower part of the second housing 120, and the fan blade mounting seat 220 is rotatably connected to the rotating bracket 300 through the rotating shaft 340, so that the air duct assembly 200 is rotatably connected to the second housing 120 through the rotating shaft 340 and the rotating bracket 300. Among them, the rotating shaft 340 is perpendicular to the rotation axis of the crossflow fan blade 210, ensuring that when the air duct assembly 200 is maintained, the air duct assembly 200 can be turned over in the vertical direction and extended out of the second housing 120.

[0064] It should be understood that in other embodiments, the air conditioner 010 is not equipped with the rotating bracket 300, and the air duct assembly 200 is directly connected to the second shell 120 via the rotating shaft 340, which is not specifically limited here.

[0065] The structure of the rotating bracket 300 can be set as required; please refer to Figure 1 , Figure 5 and Figure 6 In this embodiment, the rotating bracket 300 includes a first plate 310 and a second plate 320 connected at an angle, the first plate 310 is connected to the second housing 120, and the air duct assembly 200 is rotatably connected to the first plate 310 via a rotating shaft 340. The first plate 310 and the second plate 320 connected at an angle ensure the structural strength of the rotating bracket 300 itself, and can prevent the rotation of the air duct assembly 200 from being restricted or blocked by the structure of the rotating bracket 300, that is, it can ensure that the air duct assembly 200 can smoothly rotate relative to the second housing 120.

[0066] Furthermore, the rotating bracket 300 also includes a reinforcing rib 330 connected between the first plate 310 and the second plate 320 ; the provision of the reinforcing rib 330 can improve the structural strength between the first plate 310 and the second plate 320 .

[0067] Furthermore, a notch 311 is provided at one end of the first plate 310 away from the second plate 320; the rotating bracket 300 further includes two first connecting ears 312, both of which are connected to the first plate 310 and are distributed on both sides of the notch 311; both of the first connecting ears 312 are provided with a first hole 313, and the rotating shaft 340 is plugged into the first holes 313 of the two first connecting ears 312; the lower end of the fan blade mounting seat 220 is connected with two second connecting ears 223, both of which are distributed at intervals and are provided with a second hole 224, and the rotating shaft 340 is also plugged into the second hole 224. Such a configuration ensures that the air duct assembly 200 is reliably rotatably connected to the rotating bracket 300 through the rotating shaft 340.

[0068] Optionally, the shaft 340 is fixedly connected to the first connecting ear 312 and rotatably inserted into the second hole 224; or, the shaft 340 is fixedly connected to the second connecting ear 223 and rotatably inserted into the first hole 313; or the shaft 340 is rotatably inserted into both the first hole 313 and the second hole 224.

[0069] Optionally, the connection method between the first plate 310 and the second shell 120 includes but is not limited to bonding, connecting with fasteners such as bolts, etc.

[0070] Please refer to Figure 6 In this embodiment, the rotating bracket 300 is provided with a supporting portion 321, and the air duct assembly 200 is provided with a resisting portion 221; specifically, the second plate 320 is provided with a supporting portion 321, and the fan blade mounting seat 220 is connected with the resisting portion 221; when the air duct assembly 200 rotates to extend out of the second housing 120, the supporting portion 321 can resist the resisting portion 221 to lift the air duct assembly 200, so that the air duct assembly 200 is kept in a horizontal state. By using the resisting cooperation between the supporting portion 321 and the resisting portion 221, the air duct assembly 200 is lifted, and the air duct assembly 200 can be relatively stably suspended in the air, thereby facilitating the cleaning and maintenance of the air duct assembly 200, reducing the bending and squatting movements of the personnel who change and wash the air duct assembly 200, and reducing the labor intensity.

[0071] It should be understood that in some embodiments, a third shell 130, and a supporting portion 321 and a supporting portion 221 that can abut against each other can be selectively provided, that is, the air duct assembly 200 that is rotated and moved out of the second shell 120 can be lifted only by the third shell 130, or the supporting portion 321 and the abutting portion 221 that can abut against each other.

[0072] It should be noted that the support portion 321 is the upper surface of the second plate 320, that is, the support portion 321 is the side surface of the second plate 320 facing the first plate 310; the abutting portion 221 is located at the lower end of the fan blade mounting seat 220 and is connected to the side of the fan blade mounting seat 220 facing the first shell 110; this arrangement ensures that when the air duct assembly 200 is rotated and moved out of the second shell 120, the abutting portion 221 can reliably abut against the support portion 321 to ensure that the air duct assembly 200 is reliably supported.

[0073] Furthermore, when the air duct assembly 200 rotates to extend out of the second housing 120, the abutting portion 221 can also abut against the reinforcing rib 330 to limit the air duct assembly 200 from further rotating. In this way, the abutting portion 221 and the reinforcing rib 330 can also be used to prevent the air duct assembly 200 from excessively rotating. Moreover, the abutting portion 221 can abut against the reinforcing rib 330 and the supporting portion 321 at the same time, which can ensure the stability of the air duct assembly 200 after it rotates and extends out of the second housing 120, thereby ensuring that the replacement and cleaning of the air duct assembly 200 can be carried out smoothly.

[0074] Furthermore, the air duct assembly 200 is provided with a limiting member 222; when the air duct assembly 200 rotates to extend out of the second shell 120, the limiting member 222 can abut against the rotating bracket 300 to limit the air duct assembly 200 from continuing to rotate; specifically, the fan blade mounting seat 220 is connected to the limiting member 222, and when the air duct assembly 200 rotates to extend out of the second shell 120, the limiting member 222 can abut against the first plate 310. The setting of the limit member 222 can not only prevent the air duct assembly 200 from excessive rotation; moreover, the weight of the air duct assembly 200 is relatively large. When the air duct assembly 200 is rotated toward the outside of the second shell 120, the limit member 222 and the supporting portion 221 are easily impacted and may be damaged. In particular, when the person changing clothes accidentally fails to hold the air duct assembly 200 steadily, the air duct assembly 200 rotates to the outside of the second shell 120 under the action of its own weight, causing the limit member 222 and the supporting portion 221 to be impacted more, and more easily causing the limit member 222 and the supporting portion 221 to be damaged; therefore, when the air duct assembly 200 uses both the limit member 222 and the supporting portion 221 to prevent the air duct assembly 200 from excessive rotation, it can also avoid the problem that the air duct assembly 200 cannot be prevented from excessive rotation when one of the limit member 222 and the supporting portion 221 is damaged.

[0075] It should be understood that in some embodiments, the air duct assembly 200 can be prevented from excessive rotation only by the mutual abutment between the abutting portion 221 and the reinforcing rib 330, or only by the abutment between the limiting member 222 and the first plate 310.

[0076] Optionally, the limiting member 222 is connected to the lower end of the fan blade mounting seat 220 and is distributed close to the rotating shaft 340, for example, the two second connecting ears 223 are both connected to the limiting member 222; when the air duct assembly 200 rotates to extend out of the second housing 120, the limiting member 222 can abut against the end of the first plate 310 away from the second plate 320. This arrangement can prevent the limiting member 222 from hindering the air duct assembly 200 from rotating out of the second housing 120.

[0077] Of course, in other embodiments, the limit member 222 can also be connected to the side of the fan blade mounting base 220 facing the first shell 110, and when the air duct assembly 200 rotates to extend out of the second shell 120, it can abut against the second plate 320 or the reinforcing rib 330 to prevent the air duct assembly 200 from excessive rotation.

[0078] When the air duct assembly 200 of the air conditioner 010 of this embodiment needs to be maintained, the following process can be followed: the first housing 110 is disassembled from the second housing 120, and the air outlet frame assembly 150 is disassembled synchronously with the first housing 110; the connection between the end of the air duct assembly 200 away from the rotating shaft 340 and the second housing 120 is released, and the air duct assembly 200 is rotated around the rotating shaft 340 until it extends out of the second housing 120. At this time, the air duct assembly 200 can be lifted by the third housing 130 and the rotating bracket 300, and the air duct assembly 200 can be maintained. When the maintenance is completed, the air duct assembly 200 can be rotated again to be installed back into the second housing 120, and the first housing 110 can be installed on the second housing 120, and the air outlet frame assembly 150 can be installed and reset synchronously with the first housing 110.

[0079] In summary, the air conditioner 010 of the utility model can improve the operability and efficiency of cleaning and maintaining the air duct assembly 200; and when cleaning and maintaining the air duct assembly 200, the air duct assembly 200 can be lifted up, and the air duct assembly 200 can be cleaned directly next to the second shell 120, without the need to completely remove the air duct assembly 200 from the second shell 120, thereby improving the problem that it is difficult to completely remove the air duct assembly 200 from the second shell 120 and the cleaning is troublesome. At the same time, it can also improve the problem that the air duct assembly 200 is difficult to reinstall after being completely removed from the second shell 120.

[0080] Although the utility model is disclosed as above, the utility model is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the utility model. Therefore, the protection scope of the utility model shall be subject to the scope defined by the claims.
