Therefore, by setting the interval between the two communication ports 11 within the above range, it is possible to facilitate efficient air outlet or air inlet.
The third embodiment of the present invention provides a panel assembly, and the panel assembly in the third embodiment is different from the panel assembly in the first embodiment in the layout manner of the communication expansion. The communication port 11 in this embodiment includes at least a first communication port and a second communication port, and the setting height of the first communication port and the setting height of the second communication port are different. The height of the first communication port is h 1 ，0.5 ＜h 1 The H is less than 1, and the first communication port is communicated with the air inlet 21; the height of the second communication port is h 2 ；0＜h 2 The H is less than 0.5, and the second communication port is communicated with the air outlet 22; and/or the length of the panel 10 is L, and the distance between the first communication port and the second communication port is L 1 ， 0.5＜l 1 /L≤0.9。

The height of the first communication port is h 1 ，0.5＜h 1 And H < 1, the first communication port is communicated with the air inlet 21, so that the first communication port is arranged close to the air inlet 21, and the air inlet quantity is increased better. The height of the second communication port is h 2 ；0＜h 2 and/H is less than 0.5, and the second communication port is communicated with the air outlet 22, so that the second communication port is arranged close to the air outlet 22, and the air outlet quantity is increased better. The panel 10 has a length L and a distance L between the first communication port and the second communication port 1 ，0.5＜l 1 With L less than or equal to 0.9, the structure layout is adopted, thereby facilitating the use ofThe distance between the first communication port and the second communication port is as large as possible, so that the mutual interference between the air inlet at the first communication port and the air inlet at the second communication port is avoided, the air inlet quantity is increased through the first communication port better, and the air outlet quantity is increased through the second communication port.
As shown in fig. 8, in the third embodiment of the present invention, two diagonally symmetrical circular grille openings are provided on the panel 10, wherein the communication opening 11 with the upper right corner close to the upper end of the panel 10 body is used for air intake, the communication opening 11 with the lower left corner close to the lower end of the panel 10 body is used for air exhaust, the center positions of the communication openings 11 are respectively located at the positions 2L/5 from the center line from the upper and lower edges H/4 of the panel 10, the opposite directions of the corresponding motors are realized through the controller, and meanwhile, the distance between the air inlet and the air outlet 22 is far, so that the air flow is prevented from generating a loop between the two, and the effect of increasing the air intake and the air exhaust is achieved.
In the three embodiments described above, the panel 10 has a length L and a height H. Specifically, the communication port 11 may be a circular port, and the diameter of the communication port 11 is d, where d is 0 < 0.5H, so that the size of the communication port 11 is in a suitable range, thereby avoiding the situation that the undersize of the communication port 11 affects the air inlet or the air outlet, and also avoiding the situation that the oversized size of the communication port 11 affects the layout position of the communication port 11. Alternatively, the communication port 11 is a square port, the length of the communication port 11 is a, the width is b,0 < a is less than or equal to 0.5L,0 < b is less than or equal to 0.5H, and by adopting the size range, the situation that the size of the communication port 11 is too small to influence the air inlet or the air outlet and the size of the communication port 11 is too large to influence the layout position of the communication port 11 can be avoided.
In each of the above three embodiments, a panel assembly is provided that is capable of assisting in air intake. The panel 10 is provided with a plurality of grill openings, and the driving part 31 (the driving part 31 may be a motor) is fixed to the panel 10 through the mounting bracket 50. The main stream air conditioner indoor unit in the market at present is limited by the internal structure, the sizes of the air inlet and the air outlet 22 cannot be adjusted, the refrigerating capacity is required to be improved by adjusting the rotating speed, but the rotating speed cannot be continuously improved beyond a certain range, and the requirements of increasing the air inlet or the air outlet can be met through the communication port 11 in the three embodiments.
In an alternative embodiment, the shape of the communication port 11 is not necessarily designed as a circular grid, the shape of the communication port 11 may also be square or strip, and the specific shape may be adjusted according to the appearance requirement. The length of the single communication port 11 does not exceed L/2 and the width does not exceed H/2. The number of the communication ports 11 on the panel 10 is not necessarily two, and the communication ports can be adjusted according to the requirement of the air inlet area. However, the total length of all the communication ports 11 in the length direction is required to be less than 3L/4, the total width in the width direction is required to be less than H/2, and the corresponding number of motors, fan blades 32 and the like also changes. When the communication ports 11 on the panel 10 are used for air intake, the position of the center position of each communication port 11 in the width direction is less than 2H/5 from the upper edge of the panel 10; similarly, when the communication ports 11 on the panel 10 are used only for air outlet, the position of the center position of each communication port 11 in the width direction is less than 2H/5 from the lower edge of the panel 10, and when different communication ports 11 exist simultaneously to achieve air inlet and air outlet respectively, the distance of the center position of each communication port 11 from the upper edge or the lower edge of the panel 10 is less than H/4, and the distance of the center position of each communication port 11 from the center line of the panel 10 is greater than L/4. The mounting bracket 50 does not have to be provided with three supports (i.e., three connection plates 52), and can be appropriately adjusted under the condition of satisfying stability and internal space.
Another aspect of the present invention provides an air conditioning indoor unit, which includes the panel assembly provided above, so as to increase the air intake or the air output through the communication port 11 on the panel assembly.
From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects: the panel assembly is provided with a grille opening to serve as an auxiliary air inlet/outlet, and the panel assembly also comprises an axial flow fan blade, a motor, a bracket and other structures. When the air conditioner is started, the motor is started simultaneously, the motor and the fan blade can be equivalent to an air draft device, the air draft can be increased under the same rotation speed of the indoor unit before the air draft of the air inlet at the upper end of the panel body reaches saturation, the performance of the indoor unit can be further improved, when the air draft of the air inlet at the upper part of the panel body reaches saturation, the rotation speed of the indoor unit can not be improved continuously, the noise and the like can be easily caused, and the performance of the indoor unit can be further improved through the extra air draft provided by the air draft device. In addition, the rotating speed of the motor in the assembly can be adjusted according to different air inlet amounts corresponding to different rotating speeds of the indoor unit. Similarly, when the air outlet needs to be increased, the motor can be reversed, so that the air can be converted into a blowing device from the air draft device, and the air outlet quantity is improved under the condition that the size of the air outlet at the lower end of the panel body is unchanged. In addition, when the air inlet and the air outlet are required to be increased simultaneously, the controller can realize that a part of motors rotate positively and a part of motors rotate reversely, so that the expected effect is achieved.

Thus, other examples of the exemplary embodiments may have different values. It should be noted that: like reference numerals and letters denote like items in the following figures, and thus once an item is defined in one figure, no further discussion thereof is necessary in subsequent figures.
In the description of the present application, it should be understood that, where azimuth terms such as "front, rear, upper, lower, left, right", "transverse, vertical, horizontal", and "top, bottom", etc., indicate azimuth or positional relationships generally based on those shown in the drawings, only for convenience of description and simplification of the description, these azimuth terms do not indicate and imply that the apparatus or elements referred to must have a specific azimuth or be constructed and operated in a specific azimuth, and thus should not be construed as limiting the scope of protection of the present application; the orientation word "inner and outer" refers to inner and outer relative to the contour of the respective component itself.
Spatially relative terms, such as "above … …," "above … …," "upper surface at … …," "above," and the like, may be used herein for ease of description to describe one device or feature's spatial location relative to another device or feature as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "above" or "over" other devices or structures would then be oriented "below" or "beneath" the other devices or structures. Thus, the exemplary term "above … …" may include both orientations of "above … …" and "below … …". The device may also be positioned in other different ways (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.
In addition, the terms "first", "second", etc. are used to define the components, and are merely for convenience of distinguishing the corresponding components, and unless otherwise stated, the terms have no special meaning, and thus should not be construed as limiting the scope of the present application.
The above description is only of the preferred embodiments of the present invention and is not intended to limit the present invention, but various modifications and variations can be made to the present invention by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
