Description

Technical Field

[0001] This application relates to the technical field of air conditioners, and more particularly, to a floor-standing air conditioner. Background Art

[0002] The cross-flow fan blades installed in the air duct assembly of a floor-standing air conditioner often need to be cleaned regularly. In the industry, most of the air duct assemblies and air outlet frame assemblies of floor-standing air conditioners are stacked and installed layer by layer, and when disassembling, the components also need to be disassembled layer by layer from the outside to the inside. For example, when cleaning and maintaining the cross-flow fan blades, the casing must be disassembled first, then the air outlet frame assembly is removed, followed by removing the air duct assembly, and finally the cross-flow fan blades inside the air duct assembly can be cleaned. Therefore, the operation of cleaning and maintaining the cross-flow fan blades of the floor-standing air conditioner in the related art is cumbersome, seriously affecting the maintenance efficiency. Summary of the Invention

[0003] The problem solved by this application is that the cleaning and maintenance efficiency of the cross-flow fan blades in the air duct assembly of the existing floor-standing air conditioner is low.

[0004] To solve the above problems, this application provides a floor-standing air conditioner, including a casing and an air duct assembly disposed inside the casing. The air duct assembly includes a cross-flow fan blade and a fan blade mounting seat. Both axial ends of the cross-flow fan blade are rotatably connected to the fan blade mounting seat; the casing includes a first casing and a second casing, and the first casing and the second casing are detachably connected to enclose an inner cavity of the casing. A rotating bracket is provided on the second casing, and the rotating bracket includes a rotating shaft. One axial end of the fan blade mounting seat is pivotally connected to the rotating shaft. After the first casing is removed, the air duct assembly can rotate around the rotating shaft in the vertical direction and extend out of the second casing.

[0005] The floor-standing air conditioner provided by the embodiments of this application rotates and connects the air duct assembly to the second casing by setting a rotating bracket, so that when maintenance of the air duct assembly is required, only the first casing needs to be removed, and then the entire air duct assembly is rotated to extend it out of the second casing, and then maintenance can be performed on it (such as cleaning the cross-flow fan blades). Therefore, when maintaining the air duct assembly, it is not necessary to take out the entire air duct assembly from the casing, but one end of it is always rotatably connected to the second casing; after the maintenance is completed, the air duct assembly is rotated back to its original position, and then the first casing is installed to complete the assembly. Since the floor-standing air conditioner provided by the embodiments of this application does not need to completely take out the air duct assembly from the casing when maintaining the air duct assembly, the maintenance efficiency can be improved.

[0006] In an alternative embodiment, the rotating shaft is perpendicular to the axis of the cross-flow fan blade. The cross-flow fan blade is usually in an upright state in the assembled state. By setting the rotating shaft perpendicular to the axis of the cross-flow fan blade, when maintaining the air duct assembly, the air duct assembly can be flipped in the vertical direction and extended out of the second casing.

[0007] In an alternative embodiment, the cross-flow fan blade is vertically disposed within the housing, and the lower end of the blade mounting seat is pivotally connected to the rotating shaft. By pivotally connecting the lower end of the blade mounting seat to the rotating shaft, when maintaining the air duct assembly, the upper end of the air duct assembly is turned downward, which is more labor-saving compared to turning the lower end of the air duct assembly upward.

[0008] In an alternative embodiment, the rotating bracket further includes a blocking portion, and a limiting portion is provided on the blade mounting seat. When the air duct assembly rotates around the rotating shaft to a preset position outside the second housing, the limiting portion abuts against the blocking portion to limit the further rotation of the air duct assembly. When the lower end of the air duct assembly is pivotally connected to the rotating shaft, during the maintenance of the air duct assembly, the upper end of the air duct assembly needs to be turned downward and laid down. By providing the blocking portion and the limiting portion, the air duct assembly can be supported and maintained in a laid-down posture after rotating in place, without the need for maintenance personnel to manually support or use other tools to support the air duct assembly, and the maintenance of the air duct assembly can continue.

[0009] In an alternative embodiment, the rotating bracket further includes a rotating shaft mounting seat and two fixed seats. The two fixed seats are spaced apart and are both connected to the second housing. The two rotating shaft mounting seats are respectively disposed on the two fixed seats, and both ends of the rotating shaft are respectively connected to the two rotating shaft mounting seats. The blocking portion is connected to the two fixed seats. Both ends of the rotating shaft are connected to the second housing through the rotating shaft mounting seat and the fixed seat, which can ensure its stability; the blocking portion is connected to the two fixed seats, making its position relative to the rotating shaft stable, and thus can play a good limiting role.

[0010] In an alternative embodiment, two spaced-apart connecting portions are provided on the blade mounting seat. The two connecting portions are pivotally connected to the rotating shaft, and the two limiting portions are respectively disposed on the two connecting portions. Using two connecting portions to pivotally connect to the rotating shaft can ensure the rotational connection stability between the blade mounting seat and the rotating shaft.

[0011] In an alternative embodiment, the blocking portion includes a first plate body and a second plate body connected to each other. The first plate body is used to abut against the limiting portion. The second plate body is disposed at an angle to the first plate body, and a reinforcing rib is provided at the corner formed by the first plate body and the second plate body. Since the blocking portion needs to support the air duct assembly rotated to the preset position, the first plate body and the second plate body disposed at an angle can significantly improve the anti-bending ability of the entire structure, and the reinforcing rib further strengthens the strength of the blocking portion.

[0012] In an alternative embodiment, an air inlet is provided on the second housing, and an air outlet is provided on the first housing. A cabinet air conditioner is generally placed against a wall, with its air outlet facing the indoor space and its air inlet facing the wall. Therefore, the air inlet is provided on the first housing and faces the indoor space, and the air duct assembly is rotatably connected to the second housing, which means that when maintaining the air duct assembly, the air duct assembly is turned out of the second housing from the front side of the cabinet air conditioner, thus omitting the step of turning the cabinet air conditioner around, and improving the maintenance efficiency.

[0013] In an alternative embodiment, the cabinet air conditioner further includes an air outlet frame assembly, which is connected to the air duct assembly and is located between the first housing and the air duct assembly. The air outlet frame assembly is used to adjust the air outlet direction. The air outlet frame assembly is connected to the air duct assembly. When the first housing is removed, the air outlet frame assembly is exposed, facilitating its maintenance.

[0014] In an alternative embodiment, when the air duct assembly rotates around the rotation axis to a preset position outside the second housing, the air outlet frame assembly abuts against the rotation bracket to limit the further rotation of the air duct assembly. By setting it in this way, after the air duct assembly and the air outlet frame assembly rotate to the preset position, they are limited by the rotation bracket, avoiding damage to the equipment caused by excessive rotation; when the rotation axis is connected to the lower end of the air duct assembly, it can also play a role in supporting the air duct assembly and the air outlet frame assembly, eliminating the need for the operator to hold the air duct assembly and the air outlet frame assembly by hand.

[0015] In an alternative embodiment, the impeller mounting seat is also detachably connected to the second housing through a fastening structure. The impeller mounting seat is connected to the second housing through the fastening structure in the normal assembly state, which can increase the stability of the air duct assembly during use. When it is necessary to flip the air duct assembly for maintenance, the locking of the fastening structure can be released first, and then the air duct assembly can be flipped outside the second housing for maintenance.

Detailed implementation manners

[0022] For most floor - standing air conditioners, the air duct assembly and the air outlet frame assembly are stacked and installed layer by layer from the inside to the outside. When disassembling, the components also need to be disassembled layer by layer from the outside to the inside. For example, to clean the cross - flow impeller inside the air duct assembly, it is necessary to first remove the front panel assembly, then remove the air outlet frame assembly, then remove the air duct assembly, and finally the cross - flow impeller inside the air duct can be cleaned. Therefore, both the air duct assembly and the air outlet frame assembly need to be completely removed from the casing of the air conditioner and placed on a table or the ground for maintenance. The operation is cumbersome, seriously affecting the maintenance efficiency, and also occupying a large amount of space.

[0023] Therefore, the embodiment of the present application provides a floor - standing air conditioner. By rotatably connecting the air duct assembly to the casing, the air duct assembly only needs to be flipped to the outside of the casing, and it is not necessary to completely remove it to achieve maintenance. Therefore, the maintenance efficiency is improved, and the space occupied during maintenance is also reduced.

[0024] To make the above - mentioned objects, features, and advantages of the present application more obvious and understandable, the following detailed description of the specific embodiments of the present application will be given with reference to the accompanying drawings.

[0025] Figure 1 It is a schematic diagram of the floor - standing air conditioner 010 in an embodiment of the present application (the first housing is omitted); Figure 2 It is a schematic diagram after the air duct assembly 300 is flipped to a preset position in an embodiment of the present application. As Figures 1 to 2As shown in the figure, the cabinet air conditioner 010 provided by the embodiment of the present application includes a housing, a heat exchanger assembly 200, an air duct assembly 300, an air outlet frame assembly 400, and a rotating bracket 500. Among them, the heat exchanger assembly 200 includes a coil for refrigerant circulation, which is used to heat or cool the passing air flow; the air duct assembly 300 is used to form an air flow and restrict the flow direction of the air flow within the cabinet air conditioner 010; the air outlet frame assembly 400 is used to guide the air flow sent by the air duct assembly 300 to adjust the air flow direction sent out from the air outlet of the cabinet air conditioner 010; the rotating bracket 500 is connected to the housing and is used to realize the rotational connection between the air duct assembly 300 and the housing. The heat exchanger assembly 200, the air duct assembly 300, the air outlet frame assembly 400, and the rotating bracket 500 are all arranged inside the housing, and the housing is used to protect the above components and modules. An air inlet 110 and an air outlet are formed on the surface of the housing. When the cabinet air conditioner 010 is in use, the indoor air enters from the air inlet 110, passes through the heat exchanger assembly 200, the air duct assembly 300, and the air outlet frame assembly 400 in sequence, and then returns to the indoor from the air outlet.

[0026] In the embodiment of the present application, the housing includes a first housing (not shown in the figure) and a second housing 100. The first housing and the second housing 100 are detachably connected to enclose a housing cavity. Specifically, the first housing can be detachably connected to the second housing 100 through screws and / or snap structures. When maintaining the interior of the cabinet air conditioner 010, the first housing can be removed. In this embodiment, the overall shape of the housing is cylindrical. Therefore, both the first housing and the second housing 100 are arc-shaped housings, and the two are joined together horizontally to form the housing. In alternative other embodiments, the entire housing can also be a cuboid.

[0027] In the embodiment of the present application, the air duct assembly 300 includes a cross-flow fan blade 320 and a fan blade mounting seat 310. Both ends of the cross-flow fan blade 320 in the axial direction are rotatably connected to the fan blade mounting seat 310. It can be understood that the fan blade mounting seat 310 serves as a bracket for fixing the cross-flow fan blade 320, so that in the normal assembly state, the cross-flow fan blade 320 can keep its axis relatively fixed with respect to the housing through the fan blade mounting seat 310. Optionally, the fan blade mounting seat 310 includes two supports rotatably connected to both ends of the cross-flow fan blade 320 and a connecting frame connecting the two supports. Further, the air duct assembly 300 may further include a driving member, which is fixedly connected to the fan blade mounting seat 310 and is used to drive the cross-flow fan blade 320 to rotate.

[0028] In the embodiment of the present application, the rotating bracket 500 is connected to the second housing 100. One end of the fan blade mounting seat 310 in the axial direction of the cross-flow fan blade 320 is pivotally connected to the rotating bracket 500. After the first housing is removed, the air duct assembly 300 can rotate around the rotating shaft 510 in the vertical direction and extend out of the second housing 100, as Figure 2As shown. By setting the rotating bracket 500, the air duct assembly 300 is rotatably connected to the second housing 100. When maintenance of the air duct assembly 300 is required, only the first housing needs to be removed, and then the entire air duct assembly 300 is rotated to make it protrude from the second housing 100, so that maintenance can be carried out on it (such as cleaning the cross-flow fan blade 320). Therefore, when maintaining the air duct assembly 300, it is not necessary to remove the entire air duct assembly 300 from the casing, but one end of it is always rotatably connected to the second housing 100; after maintenance is completed, the air duct assembly 300 is rotated back to its original position, and then the first housing is installed to complete the assembly. Since the cabinet air conditioner 010 provided by the embodiment of the present application does not need to completely remove the air duct assembly 300 from the casing when maintaining the air duct assembly 300, the maintenance efficiency can be improved.

[0029] In this embodiment, the cross-flow fan blade 320 is vertically arranged in the casing (in the normal assembly state), and the lower end of the fan blade mounting seat 310 is pivotally connected to the rotating bracket 500. By pivotally connecting the lower end of the fan blade mounting seat 310 to the rotating bracket 500, when maintaining the air duct assembly 300, the upper end of the air duct assembly 300 is turned downward. Compared with turning the lower end of the air duct assembly 300 upward, this turning method is more labor-saving. It should be understood that in other alternative embodiments, the upper end of the air duct assembly 300 can also be pivotally connected to the rotating bracket 500. In this case, when maintaining the air duct assembly 300, the lower end of the air duct assembly 300 needs to be lifted upward.

[0030] In this embodiment, an air inlet 110 is provided on the second housing 100, and an air outlet is provided on the first housing. The cabinet air conditioner 010 is generally placed against the wall, with its air outlet facing the indoor space and the air inlet 110 facing the wall. Therefore, the air inlet 110 is provided on the first housing and faces the indoor space. Rotatably connecting the air duct assembly 300 to the second housing 100 through the rotating bracket 500 means that when maintaining the air duct assembly 300, the air duct assembly 300 is turned out of the second housing 100 from the front side of the cabinet air conditioner 010, which can save the step of turning the cabinet air conditioner 010 around and improve the maintenance efficiency. In other alternative embodiments, the air inlet 110 can also be provided on the first housing and the air outlet can be provided on the second housing 100. In this case, the air duct assembly 300 is laid down and maintained at the rear side of the cabinet air conditioner 010.

[0031] In this embodiment, the air outlet frame assembly 400 is connected to the air duct assembly 300 and is located between the first housing and the air duct assembly 300. The air outlet frame assembly 400 is used to adjust the air outlet direction. A plurality of rotatable air guide vanes are provided on the air outlet frame assembly 400, and the air guide vanes can be deflected under the drive of an air guide driving member (which can be a motor), so as to realize the adjustment of the air outlet direction. The air outlet frame assembly 400 is connected to the air duct assembly 300. After the first housing is removed, the air outlet frame assembly 400 is exposed, which is convenient for maintenance. When the air duct assembly 300 rotates relative to the second housing 100, the air outlet frame assembly 400 also rotates accordingly. Further, the air outlet frame assembly 400 can be detachably connected to the air blade mounting seat 310 of the air duct assembly 300 through screws and / or snap structures.

[0032] In this embodiment, the heat exchanger assembly 200 is arranged between the second housing 100 and the air duct assembly 300. Therefore, the air entering from the air inlet 110 can first pass through the heat exchanger assembly 200 for heat exchange, and then pass through the air duct assembly 300 and the air outlet frame assembly 400, and finally be sent out from the air outlet.

[0033] Figure 3 It is a partial explosion view of the cabinet air conditioner 010 in an embodiment of the present application; Figure 4 It is a schematic diagram of the cabinet air conditioner 010 in an embodiment of the present application with the first housing and the air outlet frame assembly 400 omitted; Figure 5 is Figure 4 the enlarged view of the partial VI in. As Figures 3 to 5 shown, in this embodiment, the rotating bracket 500 includes a rotating shaft 510 and a blocking portion 530, and the air blade mounting seat 310 is pivotally connected to the rotating shaft 510. Further, a limiting portion 312 is provided on the air blade mounting seat 310. When the air duct assembly 300 rotates around the rotating shaft 510 to a preset position outside the second housing 100, the limiting portion 312 abuts against the blocking portion 530 to limit the further rotation of the air duct assembly 300. When the lower end of the air duct assembly 300 is pivotally connected to the rotating shaft 510, when maintaining the air duct assembly 300, it is necessary to turn the upper end of the air duct assembly 300 downward to lay it down. By providing the blocking portion 530 and the limiting portion 312, the air duct assembly 300 can be supported to maintain the laid-down posture after rotating in place, and it is not necessary for the maintenance personnel to manually support the air duct assembly 300 with other tools, so that the air duct assembly 300 can be continuously maintained, thus improving the operation convenience.

[0034] In this embodiment, the rotating shaft 510 is perpendicular to the axis of the cross-flow impeller 320. The cross-flow impeller 320 is in an upright state in the assembled state. By setting the rotating shaft 510 to be perpendicular to the axis of the cross-flow impeller 320, when the air duct assembly 300 is maintained, the air duct assembly 300 can be turned over in the vertical direction and extended outside the second housing 100. Further, the angle at which the air duct assembly 300 is laid down can be flexibly set by setting the relative positions of the blocking portion 530 and the limiting portion 312. For example, the air duct assembly 300 can be laid down to the horizontal, that is, turned over by 90°.

[0035] Further, the rotating bracket 500 further includes a rotating shaft mounting seat 511 and two fixing seats 520. The two fixing seats 520 are spaced apart and are both connected to the second housing 100. The two rotating shaft mounting seats 511 are respectively arranged on the two fixing seats 520. The two ends of the rotating shaft 510 are respectively connected to the two rotating shaft mounting seats 511, and the blocking portion 530 is connected to the two fixing seats 520. The two ends of the rotating shaft 510 are connected to the second housing 100 through the rotating shaft mounting seat 511 and the fixing seat 520, which can ensure its stability; the blocking portion 530 is connected to the two fixing seats 520, making its position relative to the rotating shaft 510 stable, so it can play a good limiting role. In this embodiment, the two fixing seats 520 are respectively connected to the opening edge of the second housing 100 facing the first housing; specifically, the fixing seat 520 can be connected to the second housing 100 by screws.

[0036] In this embodiment, two spaced-apart connecting portions 311 are provided on the impeller mounting seat 310. The two connecting portions 311 are pivotally connected to the rotating shaft 510, and the two limiting portions 312 are respectively arranged on the two connecting portions 311. Adopting the two connecting portions 311 to be pivotally connected to the rotating shaft 510 can ensure the rotational connection stability between the impeller mounting seat 310 and the rotating shaft 510.

[0037] Optionally, when the air duct assembly 300 rotates around the rotating shaft 510 to a preset position outside the second housing 100, the air outlet frame assembly 400 can abut against the rotating bracket 500 to limit the further rotation of the air duct assembly 300. In this way, the air duct assembly 300 and the air outlet frame assembly 400 can be jointly limited by the rotating bracket 500 and kept in the preset position (such as the horizontal position) for the operator to perform maintenance. Specifically, the air outlet frame assembly 400 can abut against the blocking portion 530 of the rotating bracket 500.

[0038] Further, the blocking portion 530 includes a first plate body 531 and a second plate body 532 connected to each other. The first plate body 531 is used to abut against the limiting portion 312. The second plate body 532 is arranged at an angle with the first plate body 531, and a reinforcing rib 533 is arranged at the corner formed by the first plate body 531 and the second plate body 532. Since the blocking portion 530 needs to support the air duct assembly 300 rotated to a preset position, the first plate body 531 and the second plate body 532 arranged at an angle can significantly improve the anti-bending ability of the whole structure, and the reinforcing rib 533 further strengthens the strength of the blocking portion 530. In this embodiment, the first plate body 531 and the second plate body 532 are perpendicular to each other and form an L-shaped structure.

[0039] Optionally, the fixed seat 520, the connecting portion 311 and the blocking portion 530 of the entire rotating bracket 500 can be integrally formed to improve the structural strength.

[0040] Further, in this embodiment, the impeller mounting seat 310 is also detachably connected to the second housing 100 through a fastening structure. The impeller mounting seat 310 is connected to the second housing 100 through the fastening structure in a normal assembly state, which can increase the stability of the air duct assembly 300 during use. When it is necessary to flip the air duct assembly 300 for maintenance, the locking of the fastening structure can be released first, and then the air duct assembly 300 can be flipped outside the second housing 100 for maintenance. Optionally, the fastening structure is arranged at the upper end of the impeller mounting seat 310, and the fastening structure can be a screw and / or a buckle.

[0041] When maintaining the air duct assembly 300 of the cabinet air conditioner 010 provided in the embodiment of the present application, the following process can be followed:

[0042] First, remove the first housing from the second housing 100; release the fastening structure between the air duct assembly 300 and the second housing 100; hold the upper end of the air duct assembly 300, and turn the air duct assembly 300 and the air outlet frame assembly 400 downward together to a preset position so that the blocking portion 530 abuts against the limiting portion 312. At this time, let go. Due to the limiting effect of the blocking portion 530, the air duct assembly 300 will not continue to flip, and then the cross-flow impeller 320 can be maintained and cleaned. When the maintenance is completed, the air duct assembly 300 and the air outlet frame assembly 400 can be turned upward together to the vertical (i.e., the normal assembly position of the air duct assembly 300), and then the relative position of the air duct assembly 300 and the second housing 100 can be locked by using the fastening structure, and finally the first housing can be installed on the second housing 100 to complete the assembly.

[0043] Although the present application is disclosed as above, the present application 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 present application. Therefore, the protection scope of the present application shall be subject to the scope defined by the claims.
