All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; may be a mechanical connection; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
Referring to fig. 1 to 3, the present embodiment provides a cross flow fan for partitioned air supply, including a plurality of cross flow impellers 1 and a rotary driving mechanism disposed in an air duct of an air conditioner; the plurality of through-flow impellers 1 are coaxially arranged in sequence in an end-to-end opposite mode, the through-flow impellers 1 are connected with a rotary driving mechanism, and the rotating speeds of the through-flow impellers 1 are different.
Specifically, the cross-flow fan shown in this embodiment is an improvement of an existing cross-flow fan, and is configured such that an integrated cross-flow impeller 1 is divided into multiple sections, which are sequentially combined in the axial direction, and each segmented cross-flow impeller 1 corresponds to one air supply region.
It should be noted here that, when the plurality of through-flow impellers 1 are installed in the air duct of the air conditioner, the axial directions of the through-flow impellers 1 are perpendicular to the wind conveying direction in the air duct, the end portions of two adjacent through-flow impellers 1 may be in a separated state or a connected state, but the rotation states of two adjacent through-flow impellers 1 are not affected by each other; meanwhile, each cross flow impeller 1 can be individually provided with a rotary driving mechanism which is in driving connection with the cross flow impeller 1, or a plurality of cross flow impellers 1 can be driven by one rotary driving mechanism together, and each cross flow impeller 1 can rotate at different rotating speeds, which is not limited herein; the rotation driving mechanism may be a combination of the motor 2 and the belt transmission mechanism, or a combination of the motor and the gear transmission mechanism, and is not limited thereto, as long as the respective cross-flow impellers 1 can be driven to rotate at different rotational speeds.
Preferably, the rotary drive mechanism is connected to each of the impellers 1 simultaneously in this embodiment.
Specifically, in the present embodiment, a set of rotary driving mechanism is simultaneously connected to each of the through-flow impellers 1, so as to optimize the driving structure corresponding to each of the through-flow impellers 1, thereby greatly reducing the volume occupied by the driving structure of each of the through-flow impellers 1, facilitating the wind power transmission of each of the through-flow impellers 1 in the air duct of the air conditioner, and further, the through-flow impellers 1 can be synchronously driven to rotate at different rotation speeds by a set of rotary driving mechanism, so as to achieve the partition wind power transmission in the same time period, and achieve the grading effect.
Preferably, referring to fig. 2, the rotary drive mechanism in the present embodiment includes a motor 2, a gear shaft 3, and a plurality of gear pairs with different transmission ratios; the gear shaft 3 is arranged in parallel to the axial direction, and one end of the gear shaft 3 is connected with the output end of the motor 2; the gear pair and the through-flow impellers 1 are arranged in a one-to-one correspondence mode, the gear pair comprises a gear 4 and a gear ring 5 which are meshed with each other, the gear 4 is sleeved on the gear shaft 3 and is fixedly connected with the gear shaft 3, and the gear ring 5 is coaxially connected with the through-flow impellers 1.
Specifically, for the rotary driving mechanism shown in this embodiment, in actual operation, the gear shaft 3 connected to the gear shaft 3 is driven by the motor 2 to rotate synchronously, because the gear shaft 3 is arranged along the axial direction of each through-flow impeller 1, and the gear pairs are arranged in one-to-one correspondence with the through-flow impellers 1, in the rotating process of the gear shaft 3, each gear 4 on the gear shaft can drive the corresponding gear ring 5 on each through-flow impeller 1 to rotate synchronously, and because the gear transmission ratios of the gear pairs are different, the rotating speeds of the through-flow impellers 1 during synchronous rotation are different, therefore, the rotary driving mechanism fully utilizes the principle of the gear transmission ratios to realize the step-by-step speed change of each through-flow impeller 1, and achieves the effect of zone air conveying.
It should also be noted here that in the present embodiment, a servomotor known in the art can be used as the motor 2; by setting the number of teeth of the gear 4 and the gear ring 5 in the gear pair, each gear pair can reach different preset transmission ratios; the gear ring 5 in each gear pair may be disposed in the middle of the cross flow impeller 1 or at the end of the cross flow impeller 1, but in the present embodiment, in order to ensure that each cross flow impeller 1 achieves a good air supply effect, the gear ring 5 is preferably disposed at the end of the cross flow impeller 1.
Preferably, the gear shaft 3 is arranged in the through-flow impeller 1 in the embodiment, and the gear ring 5 is an inner gear ring; or the gear shaft 3 is positioned outside the through-flow impeller 1, and the gear ring 5 is an outer gear ring.
Specifically, in the structure shown in fig. 1, a design scheme is given in which the gear shaft 3 is embedded in the cross-flow impeller 1, and in the scheme, the gear ring 5 is an inner gear ring so as to be meshed with the corresponding gear 4 on the gear shaft 3; the gear shaft 3 is arranged in the through-flow impeller 1, so that the volume occupied by the rotary driving mechanism in an air duct of the air conditioner is greatly reduced. When the gear ring 5 is an outer gear ring, the gear shaft 3 needs to be arranged outside the through-flow impeller 1 so that the corresponding gear 4 on the gear shaft 3 is meshed with the gear ring 5, and the design scheme effectively ensures that each through-flow impeller 1 can well carry out wind power transmission; it should be noted here that, whether the gear shaft 3 is disposed inside the tubular impeller 1 or outside the tubular impeller 1, the gear shaft 3 should be disposed on a side of the tubular impeller 1 biased toward the suction side thereof in order to reduce the influence of the gear shaft 3 on the wind power transmission of each tubular impeller 1 as much as possible.
Preferably, in order to further ensure the stability of the rotation of the gear shaft 3, the present embodiment connects a bearing seat 6 to one end of the gear shaft 3 far away from the motor 2, and the bearing seat 6 and the motor 2 are separately arranged on both sides of the plurality of through-flow impellers 1, so that the motor 2 can provide a driving force for the rotation of the gear shaft 3 at one end thereof and the bearing seat 6 can provide a stable rotation support for the rotation of the gear shaft 3 at the other end thereof.
Preferably, the ends of two adjacent tubular impellers 1 in the embodiment are connected through a rotating nesting structure; the rotary nesting structure comprises a first end ring 7 and a second end ring 8 which are coaxially embedded into a whole, wherein the first end ring 7 and the second end ring 8 are oppositely arranged at the ends of two adjacent cross-flow impellers 1.
Specifically, as can be seen from the structures shown in fig. 3 and 4, on one hand, the nested structure formed by the first end ring 7 and the second end ring 8 serves as a rotational connection between the ends of two adjacent cross-flow impellers 1, so that the two adjacent cross-flow impellers 1 rotate coaxially, and the rotational motions between the two adjacent cross-flow impellers 1 are not affected by each other; on the other hand, for each cross-flow impeller 1, the first end ring 7 and the second end ring 8 are also respectively used as mounting frameworks for connecting two ends of a plurality of blades arranged along the circumference, and when the cross-flow impellers are mounted in a matched manner, only a rotary nesting structure formed by the first end ring 7 and the second end ring 8 which are oppositely arranged on the two adjacent cross-flow impellers 1 is needed, so that the structure is simple, and the assembly is convenient.
Preferably, a rotary bearing 9 is installed between the first end ring 7 and the second end ring 8 in this embodiment.
Specifically, in order to further reduce the rotational friction between the first end ring 7 and the second end ring 8, a rotational bearing 9 is provided between the first end ring 7 and the second end ring 8; as shown in fig. 4, the outer side wall of the first end ring 7 and the inner side wall of the second end ring 8 are provided with annular positioning grooves which are oppositely arranged, and the rotary bearing 9 is installed in a cavity formed by the two annular positioning grooves, so that the rotary bearing 9 can stably rotate and operate, and can not slide along the axial direction when in operation.
Preferably, the ring gear 5 is provided on the first end ring 7 or on the second end ring 8 in this embodiment.
Specifically, in order to further optimize the installation structure of the gear ring 5, the gear ring 5 and the first end ring 7 or the second end ring 8 may be designed as an integral structure; since the gear pairs and the cross flow impellers 1 are arranged in one-to-one correspondence in this embodiment, it is preferable that the gear ring 5 and the second end ring 8 are designed as an integral structure, and the gear ring 5 is preferably an inner gear ring, and the inner gear ring is mounted on the inner side wall of the second end ring 8, see fig. 4.
Preferably, the axial direction in this embodiment is transverse or longitudinal.
Specifically, when the axial direction is horizontal, the cross-flow fan shown in this embodiment may be used in a wall-mounted air conditioner, that is, the cross-flow fan shown in this embodiment is installed horizontally in an air duct of the wall-mounted air conditioner and corresponds to an air opening arranged horizontally in the wall-mounted air conditioner, so that when the wall-mounted air conditioner supplies air to a room, a plurality of air supply areas may be formed horizontally in sequence, and a grading effect may be achieved.
Meanwhile, when the axial direction is longitudinal, the cross-flow fan shown in the embodiment can be used for a vertical cabinet air conditioner, that is, the cross-flow fan shown in the embodiment is in a longitudinal installation state in an air duct of the cabinet air conditioner and corresponds to an air port longitudinally arranged on the cabinet air conditioner, so that when the cabinet air conditioner supplies air to a room, a plurality of air supply areas can be sequentially formed along the longitudinal direction, a grading effect is achieved, and the requirement of people on the diversity of air supply is met.
The embodiment of the invention also provides an air conditioner, which comprises a shell and the cross flow fans which are arranged in the shell and used for supplying air in a partition mode, wherein each cross flow impeller 1 of each cross flow fan used for supplying air in a partition mode is arranged in an air duct of the air conditioner.
