In particular, the first and second air blowing parts 10 and 20 may be integrally provided, so that the manufacturing cost of the two parts may be reduced, and the first and second air blowing parts 10 and 20 may be fixed at an optimal relative position when the first and second air blowing parts 10 and 20 are designed, thereby achieving an optimal air blowing effect.
When the first blowing part 10 and the second blowing part 20 are integrally provided, the first blowing part 10 may include the first inner peripheral wall 11, the first outer peripheral wall 12, and the 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, the guide plate 80 may be connected to the wall surface of the front end wall 17 defining the first annular chamber 13. In other words, the drainage flaps 80 are connected to the wall of the front end wall 17 close to the first annular chamber 13, but the drainage flaps 80 are completely located in the first annular chamber 13 and do not extend out of the first annular chamber 13. In particular, the outer end edge of the drainage tab 80 may be connected to the first peripheral wall 12, which makes the positioning of the drainage tab 80 more stable. To facilitate machining of the tab 80, in one particular embodiment, the tab 80, the front end wall 17 and the first peripheral wall 12 may be integrally formed.
In order to make the diffusion area of the air flow ejected from the first and second air outlets 15 and 25 larger, in one embodiment, the front end of the first air 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 expands outward while extending forward. 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. In order to further increase the diffusion area of the airflow, the portion of the flow guide portion 30 farther from the front end wall 17 may be configured such that the increase rate of the aperture thereof is faster.

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 change laws of the airflows 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 move along the circumferential direction due to mutual interference, and further the overall air outlet effect of the first air outlet 15 and the second air outlet 25 is enhanced.
The air supply assembly 60 may further include 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 then 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.
The overall wind outlet effect of the air supply assembly 60 is affected by the isolation degree of the first wind inlet 14 and the second wind 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, and the two fans 50 are communicated with the two chambers one by one (the chamber 41 is communicated with the first air inlet 14, and the chamber 42 is communicated with the second air inlet 24), so that a structure that the two fans 50 supply air to the two air inlets separately is realized.
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.
In addition, when the air conditioning indoor unit 70 includes the air blowing unit 60 that ejects the air flow from the two fans 50 into the first outlet 15 and the second outlet 25, respectively. One of the fans 50 may be configured to deliver an airflow after heat exchange by the heat exchange component of the indoor air conditioning unit 70, and the other fan 50 may be configured to deliver an ambient airflow (i.e., an airflow generated by the fan 50 extracting ambient air outside the indoor air conditioning unit 70, and the airflow does not undergo heat exchange by the heat exchange component 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.
