The present disclosure relates to the technical field of an air treatment device, and in particular to an air blower assembly and a ducted air conditioner.
Generally, an indoor unit of an air conditioner includes at least two air ports, one is only used for air exhaust and the other one is only used for air return, and airflow flows between the two air ports through the rotation of an air blower in the indoor unit of the air conditioner. With the continuous improvement of people's pursuit on the comfortability of the air conditioner, the indoor unit of the air conditioner is required to change the air outlet direction according to the working mode, but due to the directional requirements of a fan blade of the air blower, it is difficult to change the airflow direction after a motor driving the fan blade to rotate is reversed, so that the air outlet direction of the indoor unit cannot be adjusted, thus the air outlet direction is single, and it is difficult to meet the diversified requirements of users.
In some related arts, a plurality of mixed flow air blowers are provided so that the mixed flow air blowers turn 180° in the indoor unit of the air conditioner, and reversed air exhaust is achieved. However, in these schemes, the plurality of mixed flow air blowers are arranged on respective bases in parallel, and each of the mixed flow air blowers rotates independently along an axis perpendicular to the base. This structure is not only more complicated, but also necessary to keep a rotation gap between the adjacent two air blowers to prevent the mutual interference between the adjacent air blowers during rotation, so that the space occupation rate of the whole air blower assembly is increased, and thus the product competitiveness is reduced. Therefore, how to reduce the space occupation rate of the air blower assembly and simplify the structure are urgent problems to be solved in the field.

In this embodiment, the rotation of the air blowers 10 refers to the overall rotation of the air blowers 10 rather than the rotation of blades in the air blowers 10. According to the air blower assembly of the embodiments of the present disclosure, the rotating axes of all the air blowers 10 are collinear, so that a rotation gap is not reserved between the air blowers 10, a distance between the air blowers 10 can be shortened, even the air blowers are connected together, thereby greatly reducing the space occupation rate of the air blower assembly, shortening the overall length of the air conditioner and improving the product competitiveness.
In the related art, the air blowers 10 are separately mounted with the bracket. Therefore, both the structure of the bracket and the assembling mode of the air blowers 10 are very complicated. In the assembling and disassembling process, an operator needs to perform an assembling and disassembling operation in a suspended ceiling, so the mounting and operation processes are very inconvenient.
In some embodiments, the air blower assembly further includes a mounting bracket 30, and the plurality of air blowers 10 are connected to the mounting bracket 30. Specifically, as shown in
In some embodiments, at least one of the plurality of air blowers 10 is connected to the driving apparatus 20, and at least one of the plurality of air blowers 10 is connected to the mounting bracket 30. The driving apparatus 20 can drive the air blowers 10 to rotate on the mounting bracket 30 so as to achieve reverse air exhaust.
The plurality of air blowers 10 are fixed in the air duct through the two brackets, and the driving apparatus 20 drives the air blowers 10 to rotate so as to achieve reverse air exhaust. The air blowers 10 are arranged collinearly, so the plurality of air blowers 10 can be driven by one driving apparatus 20 at the same time, the number of the driving apparatuses 20 can be saved, and wiring is more conveniently. On one hand, the product cost is reduced without affecting the production function; and on the other hand, the overall structure is greatly simplified, the assembling space is saved and the post-maintenance is facilitated.
It should be also noted that the number and assembling modes of the driving apparatuses 20, and the assembling modes of the mounting bracket 30 may be varied. In some embodiments not shown, the number of the driving apparatuses 20 may be two or three. In a case that the number of the driving apparatuses 20 is two, one driving apparatus 20 can drive one or more air blowers 10, and the other driving apparatus 20 can drive the other air blowers 10, so that the burden of each driving apparatus 20 can be reduced. Meanwhile, in a case that one driving apparatus 20 is damaged, driving can be performed by the other driving apparatus 20, so that the operation reliability of the ducted air conditioner can be ensured.
The mounting bracket 30 may be mounted on the air blowers 10 at two ends. Referring to
In some embodiments, as shown in
In some embodiments, as shown in
In this embodiment, the first limiting portion 12 is arranged on a surface of the rotating structure 11, the second limiting portion 32 is arranged in the assembling hole 31, the first limiting portion 12 is a limiting protrusion, the second limiting portion 32 may be a limiting groove in an inner wall of the assembling hole 31, the limiting protrusion can move in the limiting groove, and a length of the limiting groove is a rotation stroke of the air blower 10. When moving to one end of the limiting groove, the limiting protrusion is in contact with an end wall of the limiting groove to form a limiting fit so as to limit the continuous rotation of the air blower 10. The rotation angle of the air blower 10 can be limited by this limiting mode, so that the air blower 10 rotates in a present angle range, thereby ensuring that the air blower 10 rotates to the preset position and improving the accuracy of the air outlet angle of the air blower 10.
It should be noted that the above embodiment is only an optimal embodiment of the specific structures of the first limiting portion 12 and the second limiting portion 32; in some other embodiments, the first limiting portion 12 and the second limiting portion 32 may adopt other fit modes. For example: the matching structures of the first limiting portion 12 and the second limiting portion 32 in the above embodiment are interchanged, that is, the first limiting portion 12 is the limiting groove, and the second limiting portion 32 is the limiting protrusion. For another example: the first limiting portion 12 is still the limiting protrusion, the second limiting portion 32 may be two limiting protrusions, and the first limiting portion 12 is located between the two limiting protrusions of the second limiting portion 32. When the air blowers 10 rotate, the first limiting portion 12 moves between the two limiting protrusions to form the rotation stroke range of the air blowers 10. When the first limiting portion 12 is in contact with one of the limiting protrusions, limiting fit is formed, the air blowers 10 continuously rotate, and vice versa.
As shown in
As shown in
In addition, the whole air blower assembly may be located at an assembling port position of the ducted air conditioner, and the mounting bracket 30 may be fixed with the air duct through a bolt at a position close to the assembling hole 31, so that the operation to the mounting bracket 30 can be facilitated in the mounting and disassembling process.
In some embodiments, the mounting bracket 30 has a handheld hole 34 for a finger to pass through, so that the air blower assembly can be carried conveniently in the assembling and disassembling process.
As shown in
Specifically, the volute casing of each of the air blowers 10 may be divided into an upper part and a lower part, that is, the first shell 13 and the second shell 14. The first shells 13 of all the air blowers 10 may be integrally formed, and the second shells 14 of all the air blowers 10 may be integrally formed. The first shells 13 and the second shells 14 are buckled to form a plurality of independent volute casing structures. In other embodiments, all the first shells 13 may be integrally formed and the second shells 14 may be independent, and vice versa.
In addition, to facilitate the maintenance of the air blowers 10, the air blowers 10 may be detachably connected.
In this embodiment, the air blower 10 is a mixed flow air blower. The mixed flow air blower is a mixed flow air blower between an axial mixed flow air blower and a centrifugal mixed flow air blower, an impeller of the mixed flow air blower makes the air do centrifugal motion and axial motion, and the airflow motion in the volute casing is mixed with two motion forms, that is, axial flow and centrifugal, so it is called “mixed flow”. The volume of the mixed flow air blower can be reduced, and the flow direction and the air pressure of the airflow can be ensured, so the mixed flow air blower is mounted in the ducted air conditioner, the wind direction can be reversible, and the air outlet direction can be changed. In other embodiments, the air blower 10 may be an axial flow air blower or a centrifugal air blower.
It should be noted that the driving mode of the driving apparatus 20 in this embodiment is electrical driving, for example, driving is performed by a motor. In other embodiments that are not disclosed, the driving apparatus 20 may be a manual driving mode, for example, by manually rotating the rotary knob. It is also possible to drive the air blower 10 through the rotary knob to rotate.
A shell of the ducted air conditioner is provided with a lower air port V1 and a side air port V2, and the air blower 10 has a first orientation and a second orientation. When the ducted air conditioner is in a cooling mode, the air blower 10 is located in the first orientation, the lower air port V1 is configured to take in air and the side air port V2 is configured to exhaust air. When the ducted air conditioner is in a heating mode, the air blower 10 is located in the second orientation, the side air port V2 is configured to take in air and the lower air port V1 is configured to exhaust air.
As shown in
The ducted air conditioner of this embodiment is subjected to simulation test, and the value of the first inclination angle a is changed, wherein upward inclination relative to the horizontal direction is a positive angle, and downward inclination relative to the horizontal direction is a negative angle. The simulation result is as follows:
According to the simulation data, in a case that α is 7.5°, the air volume reaches a maximum value, and the noise reaches a minimum value; in a case that a increases to 12°, the air volume begins to decrease and the noise begins to increase; in a case that α continuously increases to 14°, the attenuation of the air volume continuously increases and the noise increases obviously; in a case that a decreases to 0°, the air volume begins to decrease and the noise begins to increase; and in a case that α continuously decreases to −3°, the attenuation of the air volume continuously increases and the noise increases obviously. That is, in a case that the first inclination angle α is in the range of 0°≤α≤12°, the deviations of the air volume and the noise are small and the effect is the best, and the change is great after a critical value is exceeded, so that the normal work of the ducted air conditioner cannot be ensured.
In addition, in a case that the lower air port V1 serves as the air inlet, after then the air blower 10 inclines, the air suction port 15 can suck the air from a part away from a water-receiving disk, thereby avoiding the influence on the air inlet of the air blower 10 due to blocking airflow by the water-receiving disk, ensuring the air volume of the air blower 2, and finally ensuring the heat exchange efficiency of the ducted air conditioner.
As shown in
The mixed flow air blower of this embodiment is subjected to simulation test, and the value of the second inclination angle β is changed, where upward inclination relative to the horizontal direction is a positive angle, and downward inclination relative to the horizontal direction is a negative angle. The simulation result is as follows:
According to the simulation data, in a case that β is 7.2°, the air volume reaches a maximum value, and the noise reaches a minimum value; in a case that β increases to 15°, the air volume begins to decrease and the noise begins to increase; in a case that β continuously increases to 16°, the attenuation of the air volume continuously increases and the noise increases obviously; in a case that β decreases to 0°, the air volume begins to decrease and the noise begins to increase; and in a case that β continuously decreases to −2°, the attenuation of the air volume continuously increases and the noise increases obviously. That is, in a case that the second inclination angle β is in the range of 0°≤β≤15°, the deviations of the air volume and the noise are small and the effect is the best, and the change is great after a critical value is exceeded, so that the normal work of the ducted air conditioner cannot be ensured.
In a case that the lower air port V1 serves as the air outlet, after the air blower 10 inclines, most of the airflow blown out by the air exhaust port 16 flows above the water-receiving disk and is not blocked by the water-receiving disk, thereby ensuring the air volume of the air blower 10 and finally ensuring the heat exchange effect of the ducted air conditioner.
Apparently, the above implementation manners of the present disclosure are only examples for clearly describing the present disclosure and do not limit the implementation manners of the present disclosure. Those skilled in the art may make modifications in other forms based on the above description. All of the implementation manners cannot be exhausted here.
