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 ring-shaped, and may be circular ring-shaped, and the center of the first air supply part 10 defines a first center hole 16 having a hole axis X. The first center hole 16 may be a kidney-shaped hole or a circular hole, and when the first center hole has any shape, the hole axis X thereof may be understood as a center axis of the first center 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 opening 15 and the first annular chamber 13 are arranged to extend around the bore axis X of the first central bore 16. The position of the first air inlet 14 is not limited here, and it is sufficient to introduce an air flow into the first annular chamber 13.
The second blowing part 20 is located behind the first blowing part 10 and has a second outlet 25, and the specific structure of the second blowing part 20 may be any structure capable of ejecting an air flow outward in the prior art.
The first air outlet 15 and the second air outlet 25 are respectively configured to spray air flow forward along the hole axis X of the first central hole 16, and the sprayed air flow may be parallel to the hole axis X of the first central hole 16 or form a certain angle with the hole axis X of the first central hole 16. In the process of ejecting the air flow, the first air outlet 15 and the second air outlet 25 form a negative pressure behind the first central hole 16, so that the ambient air behind the first air supply part 10 is brought into the first central hole 16 by the negative pressure, and is ejected forward along the hole axis X of the first central hole 16 together with the air flow ejected from the first air outlet 15. The air flow sprayed out of the air supply assembly 60 is mixed with the ambient air flow, so the air supply effect is better.
Especially, when the air supply assembly 60 is used in an air conditioner, the heat exchange air flow (cold air during cooling and hot air during heating) ejected from the first air outlet 15 can be mixed with indoor ambient air and ejected, so that on one hand, the ambient air flow can be better guided, the ambient air in the environment can be mixed with the air after heat exchange, and the heat exchange efficiency of the ambient air and the heat exchange air in the environment can be accelerated; on the other hand, the cool air jetted out of the first air outlet 15 mixes with the ambient air flow, and the temperature is moderate, so that when the temperature of the cool air jetted out of the first air outlet 15 is too low and blows directly to the user, the user can be effectively prevented from catching a cold.
In this embodiment, since the first air outlet 15 sprays the air flow forward, a negative pressure is generated behind the first central hole 16, and this negative pressure will generate a forward thrust on the air flow sprayed in the second air supply part 20 behind the first air supply part 10, thereby enhancing the air supply effect of the second air supply part 20. Therefore, compared with the conventional structure with a single air outlet, the structure with two air outlets can increase the air supply distance of the whole air supply assembly 60 and increase the air supply amount of the whole air supply assembly 60.
The simulation experiment shows that under the same other conditions, the air outlet distance of one larger air outlet is obviously smaller than the air outlet distance of two smaller air outlets (wherein the sum of the areas of the two smaller air outlets is basically equal to the area of the larger air outlet), and the experimental data also shows that the air outlet quantity of the two smaller air outlets is 20% higher than the air outlet quantity of the larger air outlet.
The second blowing part 20 is located behind the first blowing part 10. On the one hand, the second blowing part 20 does not block the first center hole 16 and influence the flow of the external air to the first center hole 16, and on the other hand, the flow guiding effect to the external air is increased. In one embodiment, the second air supply part 20 has an annular shape, and includes a second annular cavity 23 and a second air inlet 24 communicated with the second annular cavity 23. The second air supply part 20 defines a second central hole 26 with a hole axis Y at the center, 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 have an included angle with the hole axis X of the first central hole 16. The second air outlet 25 and the second annular chamber 23 both extend around the hole axis Y of the second central hole 26, the second air inlet 24 is used for introducing air flow into the second annular chamber 23, the air flow in the second annular chamber 23 is ejected from the second air outlet 25, and the ejected air flow flows into the first central hole 16 and extends forward along the direction parallel to the hole axis X of the first central hole 16.
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 the air flow ejected from the second air outlet 25 can also guide the external ambient 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 ambient air.
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, so that 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. 1 to 3, when the first blowing part 10 and the second blowing part 20 are integrally provided, the first blowing part 10 may be provided to include a first inner peripheral wall 11, a first outer peripheral 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.
In order to increase the diffusion area of the air flow ejected from the first outlet 15 and the second outlet 25 when the first air blowing part 10 and the second air blowing part 20 are configured as described above, in one embodiment, the front end of the first air blowing part 10 is provided with the flow guiding part 30, the flow guiding part 30 extends forward along the inner edge of the front end wall 17, and the flow guiding part 30 extends forward while expanding outward, that is, the diameter of the flow guiding part 30 increases as it goes away from the front end wall 17. When the airflow ejected from the first outlet 15 and the second outlet 25 flows through the diversion part 30, the airflow attached to the inner surface of the diversion part 30 flows forward, and the airflow guided out by the diversion part 30 spreads in a substantially conical shape due to the outward expansion of the diversion part 30, and the spreading area of the airflow is larger as the airflow is farther away from the diversion part 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 one embodiment, as shown in fig. 4 to 6, when the first blowing part 10 and the second blowing part 20 are integrally formed, it may be further provided that the first blowing part 10 includes a first inner circumferential wall 11, a first outer circumferential wall 12, and a rear end wall 18. The first inner circumferential wall 11, the first outer circumferential wall 12 and the rear end wall 18 are all annular, the interior of the first inner circumferential wall 11 defining the aforementioned first central aperture 16. The first outer circumferential wall 12 extends around the first inner circumferential wall 11, and a front end edge of the first outer circumferential wall 12 is connected to a front end edge of the first inner circumferential wall 11. 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 first inner peripheral wall 11, 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, a 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 air supply part 10 and the second air supply part 20 adopt any one of the above structures, the first air inlet 14 and the second air inlet 24 may be respectively opened at the same circumferential position of the first air supply part 10 and the second air supply part 20, so that the initial positions of the airflows sprayed into the first annular cavity 13 and the second annular cavity 23 are consistent, and the directions of the airflows sprayed into the first annular cavity 13 and the second annular cavity 23 are consistent. 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 airflow change laws inside 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 interfere with each other to enable the two airflows to move along the respective circumferential directions, and further 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 passage 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 guides the air flow to the first air inlet 14 and the second air inlet 24 through the air supply passage 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 moving mutually to reduce the air outlet effect, a partition plate 43 may be disposed in the air supply channel 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, the partition 43 disposed in the air supply channel 40 may divide the air supply channel 40 into two independent chambers, the two chambers are respectively and correspondingly communicated with the first air inlet 14 and the second air inlet 24 (the chamber 41 is communicated with the first air inlet 14, and the chamber 42 is communicated with the second air inlet 24), and the two fans 50 are communicated with the two chambers one to one, so that a structure that the two fans 50 supply air to the two air inlets separately is realized.
In a second aspect of the present invention, an air conditioning indoor unit 70 is further provided, as shown in fig. 7 to 8, 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. Accordingly, the scope of the invention should be understood and interpreted to cover all such other variations or modifications.
