Abstract
Description
Technical Field
[0001] This invention relates to the technical field of air conditioners, and more specifically, to an air duct assembly and an air conditioner. Background Technology
[0002] In floor-standing air conditioners with segmented airflow control, the air guide vanes need to be segmented, requiring mounting boxes to be installed on the air outlet frame to house the upper and / or lower air guide vanes. However, the mounting boxes occupy the air outlet area of the air outlet frame. Therefore, in existing technologies, to minimize air outlet area loss, the height of the mounting boxes is kept as small as possible. However, in existing technologies, reducing the thickness of the mounting boxes leads to interference between the air guide rods of adjacent upper and lower air guide mechanisms and the rotating shafts of other components. Summary of the Invention
[0003] The first objective of this invention is to provide an air duct assembly that solves the technical problem in the prior art where the air guide rod interferes with the rotating shaft in the adjacent air guide mechanism after the thickness of the mounting box is reduced.
[0004] The air duct assembly provided by the present invention includes multiple air guiding mechanisms arranged along the blade axis. Each air guiding mechanism includes a driving component, an air guiding rod, and an air guiding blade assembly. The air guiding blade assembly includes a driving end and a driven end. The air guiding rod is disposed at the driving end. The driving component is pulsatorically connected to the air guiding rod and is used to drive the air guiding rod to rotate the air guiding blade assembly.
[0005] At least one driven end is spaced between two adjacent drive ends along the blade axis. The air guide rod has a clearance groove on the side opposite to the drive end it is connected to, for clearance of the adjacent driven end.
[0006] The air duct assembly provided by this invention can produce the following beneficial effects:
[0007] The air duct assembly provided by this invention has two adjacent air guiding mechanisms whose drive ends of the air guide blade groups are not adjacent. Therefore, taking a floor-standing air conditioner as an example, the position of the air guiding link of one air guiding mechanism in its air duct assembly can be one of three situations: located at the upper end of the uppermost air guiding mechanism, located at the lower end of the lowermost air guiding mechanism, or adjacent to the driven end of the air guide blade group of the adjacent air guiding mechanism. In the first two cases, the air guiding link will not be adjacent to the rotation shaft of the air guide blades in other air guiding mechanisms, so there is no problem of interference between them. In the third case, since the air guiding link has a clearance groove, even if the rotation shaft of the air guide blades in the adjacent air guiding mechanism moves up and down, interference between the air guiding link and the rotation shaft can be effectively avoided. Moreover, the thickness of the mounting box can be further reduced to further reduce the air outlet area loss caused by segmented air outlet control.
[0008] Furthermore, in each of the aforementioned air guiding mechanisms, the driving end is the lower end of the air guiding blade assembly, and the driven end is the upper end of the air guiding blade assembly; the lower side of the air guiding connecting rod is provided with the clearance groove.
[0009] Under this technical solution, the clearance groove on the lower side of the air guide connecting rod can avoid the rotating shaft of the driven end of the air guide blade assembly in the air guide mechanism below and adjacent to it, thereby avoiding interference between the two.
[0010] Optionally, in each of the air guiding mechanisms, the driving end is the upper end of the air guiding blade assembly, and the driven end is the lower end of the air guiding blade assembly; the upper side of the air guiding connecting rod is provided with the clearance groove.
[0011] Under this technical solution, the clearance groove on the upper side of the air guide connecting rod can avoid the rotating shaft of the driven end of the air guide blade assembly in the air guide mechanism above and adjacent to it, thereby avoiding interference between the two.
[0012] Furthermore, in each of the aforementioned air guiding mechanisms, the air guiding blade group includes N air guiding blades, and the air guiding connecting rod has (N-1) clearance slots along its length direction. The (N-1) clearance slots are respectively set to correspond one-to-one with the (N-1) air guiding blades in the adjacent air guiding mechanism that are closest to the corresponding driving member, where N is a natural number greater than 1.
[0013] The first end of the air guide rod along its length is connected to the drive component, and the second end is away from the drive component. The second end has a preset distance from the shaft of the air guide blade that is farthest from the corresponding drive component in the adjacent air guide mechanism. The preset distance can avoid interference between the second end and the shaft.
[0014] Under this technical solution, the length of the air guide rod is relatively short, which can completely avoid interference between its second end and the shaft of the air guide blade that is furthest from the corresponding drive component in the adjacent air guide mechanism; and because it is short in length and uses less material, it is lightweight and low in cost, and the output power of the drive component is also low, thereby saving energy consumption.
[0015] Optionally, in each of the air guiding mechanisms, the air guiding blade group includes N air guiding blades, and the air guiding connecting rod has N clearance slots along its length direction. The N clearance slots are arranged one-to-one with the rotating shafts of the N air guiding blades of the adjacent air guiding mechanism.
[0016] Under this technical solution, each clearance groove avoids the corresponding rotating shaft, which can also effectively prevent interference between the air guide connecting rod and the driven end of the air guide blade group in the adjacent air guide mechanism.
[0017] Furthermore, the air guide connecting rod has M pivot holes; the air guide mechanism also includes M cranks, one end of each of the M cranks is connected to the shaft of the air guide blade, and the other end is installed in the corresponding pivot hole, where M is a natural number greater than 1.
[0018] Under this technical solution, during operation, the driving component drives the air guide rod, and the air guide rod drives the air guide blades to rotate through each crank.
[0019] Furthermore, the inner wall of the pivot hole is provided with a locking platform, the mounting end of the crank is a hollow structure and is provided with a locking head, the mounting end is inserted into the pivot hole and the locking head is engaged with the locking platform.
[0020] Under this technical solution, when installing the crank, during the process of inserting its mounting end into the pivot hole, the clamp can squeeze the clamp head to deform the mounting end, so that the clamp head can more easily penetrate into the pivot hole and engage with the clamp. The engagement between the clamp and the clamp head limits the mutual movement between the air guide connecting rod and the crank, thereby ensuring the stability of the transmission.
[0021] Furthermore, the entrance end of the card station is chamfered.
[0022] Under this technical solution, when installing the crank, the beveled surface of the chamfer has a guiding effect on the mounting end of the crank, which allows the mounting end to be quickly inserted into the pivot hole, thereby improving assembly efficiency.
[0023] Furthermore, the number of air guiding mechanisms is three, namely an upper air guiding mechanism, a middle air guiding mechanism, and a lower air guiding mechanism.
[0024] Under this technical solution, the three air guiding mechanisms can achieve separate air outlets in the upper, middle and lower sections, thereby meeting more air supply needs.
[0025] The second objective of this invention is to provide an air conditioner that solves the technical problem in the prior art where the air guide rod interferes with the rotating shaft in the adjacent air guide mechanism after the thickness of the mounting box is reduced.
[0026] The air conditioner provided by the present invention includes the aforementioned air duct assembly. This air conditioner possesses all the advantages of the aforementioned air duct assembly, and therefore will not be elaborated further here. Attached Figure Description

[0040] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
[0041] This embodiment provides an air duct assembly, such as Figures 1 to 7As shown, the air duct assembly includes multiple air guiding mechanisms arranged along the blade axis. Each air guiding mechanism includes a driving member, an air guiding rod 100, and an air guiding blade assembly 300. The air guiding blade assembly 300 includes a driving end 310 and a driven end 320. The air guiding rod 100 is disposed at the driving end 310. The driving member is connected to the air guiding rod 100 for driving the air guiding rod 100 to rotate the air guiding blade assembly 300. At least one driven end 320 is spaced between two adjacent driving ends 310 along the blade axis. The side of the air guiding rod 100 away from the driving end 310 it is connected to has a clearance groove 110 for clearance of the adjacent driven end 320.
[0042] In the air duct assembly provided in this embodiment, the driving ends 310 of the guide vane groups 300 of two adjacent air guiding mechanisms are not adjacent. Therefore, taking a floor-standing air conditioner as an example, there are three possible positions for the guide rod 100 of one of the air guiding mechanisms in the air duct assembly: located at the upper end of the uppermost air guiding mechanism, located at the lower end of the lowermost air guiding mechanism, and adjacent to the driven end 320 of the guide vane group 300 of the adjacent air guiding mechanism. In the first two cases, the guide rod 100 will not be adjacent to the rotating shaft 321 of the guide vane in other air guiding mechanisms, so there is no problem of interference between them. As for the third case, since the guide rod 100 is provided with a clearance groove 110, even if the rotating shaft 321 of the guide vane in the adjacent air guiding mechanism moves up and down, interference between the guide rod 100 and the rotating shaft 321 can be effectively avoided. In addition, the thickness of the mounting box 410 can be further reduced to further reduce the air outlet area loss caused by segmented air outlet control.
[0043] It should be noted that in other embodiments of this application, the air duct assembly is applicable not only to floor-standing air conditioners but also to wall-mounted air conditioners.
[0044] Specifically, in this embodiment, as Figure 1 and Figure 3 As shown, in each air guiding mechanism, the driving end 310 is the lower end of the air guiding blade assembly 300, and the driven end 320 is the upper end of the air guiding blade assembly 300; a clearance groove 110 is provided on the lower side of the air guiding link 100. In this configuration, the clearance groove 110 on the lower side of the air guiding link 100 can avoid the rotation shaft 321 of the driven end 320 of the air guiding blade assembly 300 in the air guiding mechanism below and adjacent to it, thereby preventing interference between the two.
[0045] It should be noted that in other embodiments of this application, the configuration of the driving end 310 and driven end 320 of the guide vane assembly 300 and the clearance groove 110 of the guide rod 100 in each air guiding mechanism is not limited to the above-described form. For example, the driving end 310 can also be the upper end of the guide vane assembly 300, and the driven end 320 can be the lower end of the guide vane assembly 300; the clearance groove 110 is formed on the upper side of the guide rod 100. With this configuration, the clearance groove 110 on the upper side of the guide rod 100 can avoid the rotation shaft 321 of the driven end 320 of the guide vane assembly 300 in the air guiding mechanism above and adjacent to it, thereby preventing interference between the two.
[0046] Of course, in other embodiments of this application, the driving end 310 and driven end 320 of each guide vane group 300 need not be the same. For example, the driving end 310 of the guide vane group 300 in the uppermost guide mechanism can be set at the upper end, while the driving end 310 of the guide vane group 300 in the lowermost guide mechanism can be set at the lower end. That is, as long as there is at least one driven end 320 between two adjacent driving ends 310, instead of being directly adjacent.
[0047] It should be noted that when the drive end 310 of the air guide blade assembly 300 in the uppermost air guide mechanism is located at the top, its air guide connecting rod 100 does not need to avoid any driven end 320, but its air guide connecting rod 100 can still be provided with an avoidance groove 110 to reduce mold opening, improve production efficiency and reduce costs; similarly, when the drive end 310 of the air guide blade assembly 300 in the lowermost air guide mechanism is located at the bottom, its air guide connecting rod 100 also does not need to avoid any driven end 320, but its air guide connecting rod 100 can still be provided with an avoidance groove 110.
[0048] Specifically, in this embodiment, as Figure 1 and Figure 3 As shown, there are three air guiding mechanisms: an upper air guiding mechanism, a middle air guiding mechanism, and a lower air guiding mechanism. This configuration allows for separate airflow from the upper, middle, and lower sections, thus meeting a wider range of air supply needs.
[0049] Specifically, in this embodiment, in each air guiding mechanism, the air guiding blade group 300 includes N air guiding blades, and the air guiding connecting rod 100 has N-1 clearance slots 110 along its length direction. The N-1 clearance slots 110 are corresponding one-to-one with the N-1 air guiding blades in the adjacent air guiding mechanism that are closest to the corresponding driving component, where N is a natural number greater than 1. The first end 101 of the air guiding connecting rod 100 along its length direction is connected to the driving component, and the second end 102 is away from the driving component. The second end 102 has a preset distance from the shaft 321 of the air guiding blade in the adjacent air guiding mechanism that is farthest from the corresponding driving component. The preset distance can avoid interference between the second end 102 and the shaft 321. In this configuration, the length of the air guide rod 100 is relatively short, which can completely avoid interference between its second end 102 and the shaft 321 of the air guide blade that is furthest from the corresponding drive component in the adjacent air guide mechanism; and because it is short in length and uses less material, it is lightweight and low in cost, and the output power of the drive component is also low, thereby saving energy consumption.
[0050] More specifically, in this embodiment, as Figure 1 , Figure 2 as well as Figure 5 As shown, N=5, meaning that each guide vane group 300 includes five guide vanes, and each guide connecting rod 100 has four clearance slots 110. The four clearance slots 110 are corresponding one-to-one with the rotating shafts 321 of the four guide vanes closest to the corresponding driving component in the adjacent guide mechanism. Of course, in other embodiments of this application, the number of guide vanes in each guide vane group 300 is not limited to five, but can also be four or six, etc., and the designer can set it according to specific needs.
[0051] It should be noted that in other embodiments of this application, the arrangement of the air guide rod 100 and its clearance groove 110 in each air guide mechanism is not limited to the above-described form. For example, the air guide blade assembly 300 includes N air guide blades, and the air guide rod 100 has N clearance grooves 110 along its length direction. The N clearance grooves 110 are arranged one-to-one with the rotation shafts of the N air guide blades of the adjacent air guide mechanism. This arrangement can also effectively prevent interference between the air guide rod 100 and the rotation shaft 321 of the driven end 320 of the air guide blade assembly 300 in the adjacent air guide mechanism.
[0052] Specifically, in this embodiment, as Figure 2 , Figure 4 and Figure 6As shown, the air guide rod 100 has M pivot holes 120; the air guide mechanism also includes M cranks 200, each of which has one end connected to the shaft of the air guide blade and the other end installed in the corresponding pivot hole 120, where M is a natural number greater than 1. In this configuration, during operation, the driving component drives the air guide rod 100, and the air guide rod 100 drives the air guide blade to rotate through each crank 200.
[0053] More specifically, in this embodiment, continuing as follows Figure 2 , Figure 4 and Figure 6 As shown, the air guide connecting rod 100 has five pivot holes 120; the air guide mechanism includes five cranks 200. However, in other embodiments of this application, the number of pivot holes 120 and cranks 200 is not specifically limited, as long as the installation requirements of the air guide blade shaft 321 can be met.
[0054] Specifically, in this embodiment, as Figure 6 As shown, the first end 101 of the air guide rod 100 is also provided with a transmission connection hole for inserting the output shaft of the drive component. Preferably, the transmission connection hole is in the same form as the pivot hole 120 for mounting the crank 200.
[0055] Specifically, in this embodiment, as Figure 4 and Figure 7 As shown, a locking platform 121 is provided on the inner wall of the pivot hole 120. The mounting end 210 of the crank 200 is a hollow structure and is provided with a locking head 211. The mounting end 210 is inserted into the pivot hole 120 and the locking head 211 engages with the locking platform 121. In this configuration, when installing the crank 200, during the process of inserting its mounting end 210 into the pivot hole 120, the locking platform 121 can squeeze the locking head 211 to deform the mounting end 210, thereby making it easier for the locking head 211 to penetrate deeper into the pivot hole 120 and engage with the locking platform 121. The engagement of the locking platform 121 and the locking head 211 limits the mutual positioning between the air guide connecting rod 100 and the crank 200, thereby ensuring the stability of the transmission.
[0056] Specifically, in this embodiment, the following continues... Figure 4 and Figure 7 As shown, the inlet end of the mounting plate 121 is provided with a chamfer 122. In this configuration, when installing the crank 200, the bevel of the chamfer 122 has a guiding effect on the mounting end 210 of the crank 200, which allows the mounting end 210 to be quickly inserted into the pivot hole 120, thereby improving assembly efficiency.
[0057] This embodiment also provides an air conditioner including the aforementioned air duct assembly. This air conditioner possesses all the advantages of the aforementioned air duct assembly, and therefore will not be described in detail here.
