In the following description, the terms "front" and "rear" and the like indicating the directions refer to the air outlet direction, and when the air outlet direction changes, the direction indicated by "front" and "rear" also changes with the air outlet direction, the direction located downstream is the front, and the direction located upstream is the rear.
As shown in fig. 1-8, a preferred embodiment of the present invention is shown.
The air supply assembly 60 is used to generate and guide an air flow, and may be applied to products requiring an outward output air flow, such as a blower, an air conditioner, and a fan.
The air blowing unit 60 includes a first air blowing part 10 and a second air blowing part 20. The first air supply part 10 is annular, and may be circular, the center of the first air supply part 10 defines a first central hole 16 having a hole axis X, and the first central hole 16 may be a kidney-shaped hole or a circular hole, and the hole axis X may be understood as a central axis of the first central hole 16 regardless of the shape of the first central hole 16. The first air supply part 10 has a first air inlet 14, a first air outlet 15, and a first annular cavity 13, the first air inlet 14 is used for introducing airflow into the first annular cavity 13, and the airflow in the first annular cavity 13 is ejected from the first air outlet 15. The first outlet 15 and the first annular chamber 13 are arranged to extend around the hole axis of the first central hole 16, and the position of the first inlet 14 is not limited herein, and it is sufficient to introduce the airflow into the first annular chamber 13.
The second blowing part 20 is stacked on the first blowing part 10, and the second blowing part 20 may be located in front of the first blowing part 10 or behind the first blowing part 10, and in this embodiment, the second blowing part 20 is stacked on the rear of the first blowing part 10. The second air supply part 20 is also annular, and the center thereof defines a second central hole 26 having a hole axis Y, and the hole axis Y of the second central hole 26 may be parallel to the hole axis X of the first central hole 16 or may form an included angle with the hole axis X of the first central hole 16. The second air supply part 20 includes a second annular cavity 23, a second air inlet 24 for introducing air flow into the second annular cavity 23, and a second air outlet 25 for ejecting air flow from the second annular cavity 23, and the second air outlet 25 and the second annular cavity 23 both extend around the hole axis Y of the second central hole 26.
When the second air supply part 20 is also annular, the second air supply part 20 does not block the flow of the external air flowing into the first central hole 16, and meanwhile, the air flow ejected from the second air outlet 25 can form negative pressure behind the second central hole 26, so that the air flow ejected from the second air outlet 25 can also guide the external air, and the annular structure of the second air supply part 20 enhances the flow guiding effect of the whole air supply assembly 60 on the external air.
In this embodiment, the first air outlet 15 and the second air outlet 25 are respectively configured to eject the air flow forward along the hole axis X of the first central hole 16, and the flow rate of the air flow ejected from the first air outlet 15 is greater than the flow rate of the air flow ejected from the second air outlet 25, and the flow rate of the air flow ejected from the second air outlet 25 is greater than the flow rate of the air flow ejected from the first air outlet 15, so that the air flow ejected from the whole air supply assembly 60 can both ensure the air outlet distance and the air outlet volume. Moreover, as the air flow sprayed out of the first air outlet 15 does not need to have higher air output, the power of the fan 50 for supplying air into the first annular cavity 13 can be reduced; because the air current of spun only need guarantee the air output volume in the second air outlet 25, so can increase the opening of second air outlet 25 for the air current in the second toroidal cavity 23 can more unobstructed outflow, has strengthened air-out efficiency.
It should be noted that, technical means for realizing that the flow rate of the airflow ejected by the first air outlet 15 is greater than the flow rate of the airflow ejected by the second air outlet 25, and the flow rate of the airflow ejected by the second air outlet 25 is greater than the flow rate of the airflow ejected by the first air outlet 15 are various. For example, when the openings of the first outlet 15 and the second outlet 25 are the same, the fans 50 with different powers may be used to supply air into the first annular cavity 13 and the second annular cavity 23 separately, so that the first outlet 15 sprays airflow forward along the hole axis X of the first central hole 16, and the second outlet 25 emits air toward the periphery (i.e., conical air outlet). Preferably, the air outlet area of the first air outlet 15 can also be set to be smaller than the air outlet area of the second air outlet 25 (i.e. the total area of the first air outlet 15 is smaller than the total area of the second air outlet 25), the purpose that the flow rate of the airflow ejected from the first air outlet 15 is greater than that of the airflow ejected from the second air outlet 25 and the flow rate of the airflow ejected from the second air outlet 25 is greater than that of the airflow ejected from the first air outlet 15 can be achieved by only using one fan 50 to supply air to the first annular cavity 13 and the second annular cavity 23 at the same time (of course, when the air outlet area of the first air outlet 15 is less than that of the second air outlet 25, two fans 50 can be used to supply air to the first annular cavity 13 and the second annular cavity 23 respectively), such design simple structure conveniently makes, and can reduce fan 50's quantity, reduction in production cost.
The first air supply part 10 and the second air supply part 20 can be two mutually independent parts, and when the two parts are mutually independent, the relative positions of the two parts can be set to be adjustable, so that the air outlet direction and the air outlet size can be finely adjusted according to the needs of users, in another embodiment, the first air supply part 10 and the second air supply part 20 can be integrally arranged, the processing and manufacturing costs of the two parts can be reduced, and the first air supply part 10 and the second air supply part 20 can be fixed at the optimal relative positions when the first air supply part 10 and the second air supply part 20 are designed, so that the optimal air supply effect is achieved.
As shown in fig. 4 to 6, when the first blowing part 10 and the second blowing part 20 are integrally molded, the first blowing part 10 may include a first inner circumferential wall 11, a first outer circumferential wall 12, and a rear end wall 18.

The rear end wall 18 extends inwardly along the rear end edge of the first outer circumferential wall 12, and an edge of the rear end wall 18 close to the hole axis X of the first center hole 16 is bent forward and extends to the inside of the first inner circumferential wall 11, an inner edge of the rear end wall 18 and an inner wall surface of the first inner circumferential wall 11 together define the first air outlet 15, and the first inner circumferential wall 11, the first outer circumferential wall 12, and the rear end wall 18 together define the first annular chamber 13. Specifically, the airflow in the first annular chamber 13 is ejected from the gap between the surface of the rear end wall 18 facing the first annular chamber 13 and the surface of the first inner circumferential wall 11 facing the first central bore 16.
The second blowing section 20 includes a second inner peripheral wall 21 and a second outer peripheral wall 22. The second inner circumferential wall 21 defines the second center hole 26 described above. The second outer peripheral wall 22 extends around the second inner peripheral wall 21, and a rear end edge of the second outer peripheral wall 22 is connected to a rear end edge of the second inner peripheral wall 21, a front end edge of the second outer peripheral wall 22 is connected to the rear end wall 18, the front end edge of the second inner peripheral wall 21 and the rear end wall 18 jointly define the second air outlet 25, and the second inner peripheral wall 21, the second outer peripheral wall 22 and the rear end wall 18 jointly define the second annular cavity 23.
When the first blowing part 10 and the second blowing part 20 are integrally provided, in other embodiments, as shown in fig. 1 to 4, the first blowing part 10 may further include a first inner circumferential wall 11, a first outer circumferential wall 12, and a front end wall 17. The first inner circumferential wall 11 is annular, and the first center hole 16 of the first blowing part 10 is defined by the first inner circumferential wall 11. The first outer circumferential wall 12 extends around the first inner circumferential wall 11, and a rear end edge of the first outer circumferential wall 12 is curved outward (the "outer" referred to herein means a direction away from the hole axis X of the first center hole 16) and connected to a rear end edge of the first inner circumferential wall 11. The front end wall 17 extends along a front end edge of the first outer circumferential wall 12 in a direction toward the hole axis X near the first center hole 16, and the front end edge of the first inner circumferential wall 11 and a distal end of the front end wall 17 (the distal end referred to herein means an inner end edge of the front end wall 17 near the hole axis X of the first center hole 16, which is annular) together define the aforementioned first air outlet 15 therebetween. The first annular cavity 13 is defined by an inner space surrounded by the first inner peripheral wall 11, the first outer peripheral wall 12 and the front end wall 17.
The second blowing section 20 includes a second inner peripheral wall 21 and a second outer peripheral wall 22. The second inner circumferential wall 21 defines a second central hole 26, the second outer circumferential wall 22 extends around the second inner circumferential wall 21, a rear end edge of the second outer circumferential wall 22 is bent outward and connected to a rear end edge of the second inner circumferential wall 21, a front end edge of the second outer circumferential wall 22 is connected to the first inner circumferential wall 11, specifically, the second inner circumferential wall 11 may be connected to a rear end edge of the first inner circumferential wall 11, the front end edge of the second inner circumferential wall 21 and the first inner circumferential wall 11 together define the aforementioned second air outlet 25, and the second inner circumferential wall 21, the second outer circumferential wall 22 and the first inner circumferential wall 11 together define a second annular cavity 23.
When the first and second blowing parts 10 and 20 have the above-described structure, in order to increase the diffusion area of the air flow ejected from the first and second air outlets 15 and 25, in one embodiment, the front end of the first blowing part 10 is provided with a flow guide part 30, the flow guide part 30 extends forward along the inner edge of the front end wall 17, and the flow guide part 30 extends forward while expanding outward. When the airflow ejected from the first outlet 15 and the second outlet 25 flows through the flow guiding portion 30, the airflow attached to the inner surface of the flow guiding portion 30 flows forward, and the airflow guided out by the flow guiding portion 30 spreads in a substantially conical shape due to the outward expansion of the flow guiding portion 30, and the spreading area of the airflow is larger as the airflow is farther away from the flow guiding portion 30. To further increase the diffusion area of the airflow, in one embodiment, the portion of the flow guide 30 farther from the front end wall 17 may be configured such that the increase rate of the aperture thereof is faster.
In an embodiment, along the extending direction of the hole axis X of the first central hole 16, the front end edge of the second inner peripheral wall 21 is projected into the first central hole 16, that is, when looking from the front to the back along the hole axis X of the first central hole 16, the front end edge of the second inner peripheral wall 21 is completely visible and is not blocked by the first inner peripheral wall 11 of the first air supply part 10, so that the air flow ejected from the second air outlet 25 can more smoothly pass through the first central hole 16, thereby enhancing the overall air outlet effect of the air supply assembly 60.
Preferably, the airflow ejected from the second air outlet 25 is parallel to the direction of the hole axis Y of the second central hole 26, and specifically, the air flow ejected from the second annular cavity 23 is guided by the front edge of the first inner circumferential wall 11 and ejected along the extending direction of the hole axis Y of the second central hole 26, in which the front edge portion of the first inner circumferential wall 11 extends in the direction parallel to the hole axis Y of the second central hole 26. When the airflow of the second air outlet 25 is ejected along the hole axis Y parallel to the second central hole 26, the ejected airflow can be better guided by the airflow ejected from the first air outlet 15, so as to enhance the overall air outlet effect of the air supply assembly 60. In one embodiment, the hole axis X of the first central hole 16 and the hole axis Y of the second central hole 26 may also be arranged to coincide, so that the air flow ejected from the second air outlet 25 is ejected forward along the hole axis X parallel to the first central hole 16.
In one embodiment, the first air inlet 14 and the second air inlet 24 are opened at the same circumferential position of the first air supply part 10 and the second air supply part 20, respectively, so that the initial positions of the air flows sprayed into the first annular cavity 13 and the second annular cavity 23 are the same, and the directions of the air flows sprayed into the first annular cavity 13 and the second annular cavity 23 are the same. When the initial positions and directions of the airflows sprayed into the first annular cavity 13 and the second annular cavity 23 are consistent, the internal airflow change laws of the first annular cavity 13 and the second annular cavity 23 are the same, so that the airflows sprayed out of the first air outlet 15 and the second air outlet 25 cannot move along the circumferential direction of the first air outlet 15 and the second air outlet 25 due to mutual interference, and the overall air outlet effect of the first air outlet 15 and the second air outlet 25 is enhanced.
Specifically, the air supply assembly 60 further includes an air supply duct 40 and a fan 50 (the fan 50 may be a centrifugal fan or an axial flow fan), and the fan 50 generates an air flow and then guides the air flow to the first air inlet 14 and the second air inlet 24 through the air supply duct 40, that is, the air flow guided into the first air inlet 14 and the second air inlet 24 is provided by one fan 50, so that the manufacturing cost and the use cost can be reduced. Further, in order to avoid the air flow at the first air inlet 14 and the second air inlet 24 from flowing in series and reducing the air outlet effect, a partition plate 43 may be disposed in the air supply duct 40, and the partition plate 43 is used to isolate the first air inlet 14 and the second air inlet 24, so that the ports supplying air to the first air inlet 14 and the second air inlet 24 are as far away from the first annular cavity 13 and the second annular cavity 23 as possible.
Compared with the structure with a single air outlet, the structure with two air outlets has the air outlet effect that is affected by the isolation degree of the first air inlet 14 and the second air inlet 24. In order to further improve the air outlet effect, in an embodiment, the air supply assembly 60 includes two fans 50, the two fans 50 supply air to the first air inlet 14 and the second air inlet 24 in a one-to-one correspondence manner, and after the air flow conveyed by the fan 50 communicated with the first air inlet 14 is sprayed out from the first air outlet 15, the air flow conveyed by the fan 50 communicated with the second air inlet 24 to the second air outlet 25 is guided, so as to enhance the overall air outlet effect of the first air outlet 15 and the second air outlet 25. In particular, when there are two fans 50, the air supply assembly 60 further includes a first air inlet channel 41 and a second air inlet channel 42, the first air inlet channel 41 is communicated with the first air inlet 14, the second air inlet channel 42 is communicated with the second air inlet 24, and the two fans 50 supply air into the first air inlet channel 41 and the second air inlet channel 42 respectively. Specifically, the first air intake duct 41 and the second air intake duct 42 may be partitioned by the above-described air supply duct 40 with a partition plate 43.
As shown in fig. 7-8, the second aspect of the present invention further provides an air conditioning indoor unit 70, where the air conditioning indoor unit 70 includes the air supply assembly 60 mentioned in any of the above embodiments. The indoor air conditioner unit 70 has an air outlet 71, and the air flow ejected from the air supply unit 60 is ejected out of the indoor air conditioner unit 70 through the air outlet 71.
The third aspect of the present invention further provides an air conditioning indoor unit 70, where the air conditioning indoor unit 70 includes the air supply assembly 60, where the two fans 50 respectively and correspondingly spray air flows into the first air outlet 15 and the second air outlet 25. And one of the fans 50 delivers an air flow after heat exchange by the heat exchange part of the indoor air-conditioning unit 70, and the other fan 50 delivers an ambient air flow (i.e., the fan 50 extracts ambient air outside the indoor air-conditioning unit 70 to generate an air flow which does not undergo heat exchange by the heat exchange part of the indoor air-conditioning unit 70). Preferably, the fan 50 communicated with the first air inlet 14 delivers ambient air flow, and the fan 50 communicated with the second air inlet 24 delivers air flow after heat exchange, so that when the temperature of ambient air is reduced or increased (reduced when cooling or increased when heating) to a temperature very close to the set temperature, the ambient air can be extracted by the fan 50 communicated with the first air inlet 14 and ejected by the first air outlet 15, the air flow ejected by the first air outlet 15 guides the heat exchange air flow ejected by the second air outlet 25, so that the power of the fan 50 communicated with the second air inlet 24 can be reduced, and the power cost is saved.
In particular, in some modes of the indoor air conditioning unit 70, only the fan 50 for extracting the ambient air flow can be operated, so that the indoor air conditioning unit 70 has the functions of only blowing and not cooling, which are similar to an electric fan, and the functions can be turned on under the condition of low external temperature, thereby saving a large amount of electricity charges.
Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been illustrated and described in detail herein, many other variations or modifications consistent with the principles of the invention may be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention.
