Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of air treatment equipment, in particular to an air duct unit. Background Art
[0002] Typically, an air conditioner indoor unit includes at least two air vents: one for outlet air only and the other for return air only. The airflow is directed between the two vents by the rotation of the fan within the unit. As people's pursuit of air conditioning comfort continues to increase, indoor units need to switch the airflow direction based on the operating mode. However, due to the directional requirements of the fan blades, reversing the motor that drives the blades makes it difficult to reverse the airflow direction, making it impossible to adjust the airflow direction. This results in a single airflow direction, making it difficult to meet the diverse needs of users.
[0003] The duct air conditioner in the prior art uses a fan with adjustable air outlet direction to achieve the change of the air outlet direction of the duct air conditioner. Since the fan needs to change direction, a gap needs to be reserved between the fan and the middle partition. The fan may swing in a circle, up and down, left and right at a large angle when it falls or is transported, thereby causing interference and damage between the fan and the middle partition or dustproof plate, and even deformation of the fan structure, which may cause low reliability of the duct air conditioner. Summary of the Invention

[0033] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.
[0034] like Figures 1 to 8The ducted air conditioner shown includes: a housing 1; a middle partition 2, which is disposed in the housing 1 and divides the interior of the housing 1 into a fan chamber 11 and a heat exchange chamber; at least one fan 3, which is rotatably disposed in the fan chamber 11 and has an adjustable air outlet; a locking member 4, which is disposed on the housing 1 and has a locking structure 5, through which the locking member 4 is engaged with the fan 3. The locking member 4 is used to limit the fan 3 to the housing 1, preventing the fan 3 from swinging. This ensures that the fan 3 cannot move relative to the middle partition 2 when the ducted air conditioner is transported or dropped, thereby preventing damage to the fan 3 and related structures and effectively improving the reliability of the ducted air conditioner.
[0035] When the ducted air conditioner is in operation, in order to prevent dust and other impurities from entering the interior of the housing 1 through the air inlet on the housing 1 and causing contamination and damage to the ducted air conditioner, the ducted air conditioner further includes a dustproof plate 6. The housing 1 is provided with a first air inlet 12, which is in communication with the fan cavity 11. The dustproof plate 6 is provided at the first air inlet 12, and the locking member 4 is provided on the dustproof plate 6. The dustproof plate 6 is fixed to the housing 1 and shields the first air inlet 12. At the same time, since the first air inlet 12 is in communication with the fan cavity 11 and the fan 3 is provided in the fan cavity 11, the locking member 4 can be installed at the first air inlet 12 to lock and fix the fan 3, making it convenient to disassemble the locking member 4.
[0036] When the duct air conditioner is in normal use, when there is no need to adjust the direction of the air outlet of the fan 3, the locking member 4 can be kept in limit cooperation with the dustproof plate 6 and the fan 4, or the locking member 4 can be installed on the dustproof plate 6 after the direction of the fan 3 is adjusted to avoid displacement of the fan.
[0037] The duct air conditioner further includes a drive mechanism 7, which is disposed on the housing 1. All fans 3 are connected to a rotating shaft of the drive mechanism 7. The rotating shaft is provided with a locking structure 5, and the locking member 4 is engaged with the locking structure 5. The locking member 4 locks the rotating shaft, thereby restricting the fans 3 and preventing them from moving.
[0038] There are at least two fans 3, all of which are mounted on the rotating shaft of the drive mechanism 7. The rotating shaft is provided with at least two locking engagement structures 5, with the locking members 4 corresponding one-to-one with the locking engagement structures 5. Multiple locking members 4 are used to limit the rotating shaft at multiple points, further improving the reliability of the ducted air conditioner.
[0039] As another embodiment, the number of the fans 3 is at least two, all of which are connected in sequence. All of the fans 3 can rotate simultaneously and change the direction of the air outlet. The rotation axes of all of the fans 3 are collinear, and the fans 3 located at the ends are connected to the rotation axis of the drive mechanism 7. A connecting shaft is provided between two adjacent fans 3, and the locking structure 5 is provided on the connecting shaft. The locking member 4 is limitedly engaged with the locking structure 5. By locking the connecting shafts between the fans 3, the fans 3 are locked, thereby ensuring the reliability of the duct air conditioner.
[0040] The duct fan further includes a fan bracket 8, which is mounted on the middle partition plate 2, the drive mechanism 7, and the dustproof plate 6. The fan bracket 8 supports the drive mechanism 7 and the fan 3, ensuring that the fan 3 can rotate reliably to adjust the direction of the air outlet.
[0041] Among them, the fan bracket 8 has a first end and a second end relative to each other, the first end is arranged on the middle partition 2, and the dustproof plate 6 is arranged on the second end. At the same time, the fan bracket 8 also has a third end and a fourth end located between the first end and the second end, the third end is fixed to the top plate of the shell 1, and the fourth end is fixed to the bottom plate of the shell 1.
[0042] The duct fan further includes a shaft sleeve 9. A coupling structure is provided between two adjacent fans 3. The coupling structure is provided on the fan bracket 8 via the shaft sleeve 9. The provision of the shaft sleeve 9 reduces the friction of the fan 3 during rotation, ensuring reliable adjustment of the air outlet direction of the fan 3. When the fan falls, the fan coupling structure first contacts the shaft sleeve 9, avoiding direct contact between the coupling structure and the fan bracket 8, thereby ensuring the reliability of the fan.
[0043] To further prevent contact and collision between the coupling structure and the fan bracket 8, the ducted air conditioner further includes a sleeve bracket 9, through which the sleeve is mounted on the fan bracket 8. A vibration damping pad 10 is provided between the sleeve bracket 9 and the fan bracket 8. This ensures that when the ducted air conditioner falls, the fan 3 (coupling structure) forms soft contact with the fan bracket 8, ensuring the structural reliability of the fan 3. Moreover, because the sleeve 9 and the vibration damping pad 10 wrap around the coupling structure, the contact area is greatly increased, reducing the risk of component damage.
[0044] Preferably, the vibration damping pad 10 is a rubber pad.
[0045] The duct fan also includes a reversing bracket, which is arranged on the fan bracket 8, the driving mechanism is arranged on the reversing bracket, the sleeve is arranged on the reversing bracket through the sleeve bracket 9, and the shock-absorbing pad is arranged between the reversing bracket and the sleeve bracket 9.
[0046] The dust shield 6 is provided with a mounting hole 61, and the locking member 4 is disposed in the mounting hole 61, and the locking member 4 abuts against the dust shield 6. The mounting hole 61 allows the locking member 4 to pass through the dust shield 6 and engage with the locking engagement structure 5. Part of the locking member 4 is located in the mounting hole 61, fastening the dust shield 6 and the fan 3 together to prevent the fan 3 from moving.
[0047] The mounting hole 61 is formed with a flange structure to increase the structural strength of the mounting hole 61 and prevent the dustproof plate 6 from being pulled by the locking member 4 and thus being deformed or damaged.
[0048] As an embodiment, the locking member 4 includes a screw, a threaded hole is provided on the fan 3, the threaded hole constitutes the locking fitting structure 5, and the screw is threadedly fitted with the threaded hole.
[0049] Specifically, the screw comprises a shoulder screw, which includes a threaded engagement section, a shoulder section, and a screw head connected in sequence. The threaded engagement section is threadedly engaged with the threaded hole, and when the shoulder section abuts against the fan 3, the screw head abuts against the dustproof plate 6. This facilitates locking and limiting with the locking engagement structure 5, and prevents interference deformation of the dustproof plate 6.
[0050] The fan 3 is a mixed flow fan.
[0051] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
