For those skilled in the art, the specific meaning of the above-mentioned terms in the present invention can be understood according to specific circumstances.

First, referring to Figures 1 to 3, Figure 1 is a schematic structural diagram of the air outlet assembly of the air conditioning device in an embodiment of the present invention from a first perspective; Figure 2 is a schematic diagram of the air conditioning device in an embodiment of the present invention A schematic structural view of the air outlet assembly from a second perspective; FIG. 3 is a schematic cross-sectional view of the air outlet assembly of the air conditioning device in an embodiment of the present invention.

As shown in Figure 1, Figure 2 and Figure 3 and in accordance with the orientation of Figure 3, the air conditioning device of the present invention includes a duct machine and an air outlet assembly. The air outlet assembly includes an air storage box 1, a frame 2, a wind dispersing member 3 and The heat storage panel 4, wherein the air duct machine is connected to the air pipe inlet 11 on the side of the air storage tank 1 through the air pipe so as to communicate with the air storage tank 1, the bottom of the air storage tank 1 is connected to the frame 2, and the frame 2 corresponds to the air storage The box 1 is provided with a speed increasing port 21, the wind dispersing structure 3 is fixed on the frame 2 and located below the speed increasing port 21, and the heat storage panel 4 is disposed on the frame 2 and an attracting air duct is formed between the frame 2 , So that the external air flow can return to the inner side of the heat storage panel 4 through the induction air duct. The heat storage panel 4 includes a panel main body and an air outlet structure provided on the panel main body, and wind can be sent into the indoor space through the air outlet structure.

The air flow generated by the air duct machine enters the air storage tank 1 through the air duct inlet 11. After the air flow fills the entire air storage tank 1, the air flow enters the speed increasing port 21. The narrow speed increasing port 21 will increase the speed of the air flow to form a high speed airflow. The high-speed airflow blows toward the wind dispersing member 3 and evenly blows toward the heat storage panel 4 under the diffusion action of the wind dispersing member 3. At the same time, the high-speed airflow will also drive the surrounding air, so that the airflow of the inducement channel enters the heat storage panel 4 together, and finally enters the indoor space through the air outlet structure on the heat storage panel 4.

In order to increase the heat storage capacity of the heat storage panel 4, a heat storage space is formed inside the panel body, and the heat storage space is connected to the air outlet structure, and when the wind sent by the air duct machine flows through the heat storage panel 4, at least a part of The wind can form a vortex in the heat storage space.

The advantage of the above arrangement is that by forming a heat storage space inside the panel body, when the air flow generated by the air duct machine is sent into the indoor space through the air outlet structure, a part of the wind will form a vortex in the heat storage space. The formation makes the air flow stagnate inside the panel body, forming multiple small energy loops, thereby improving the heat storage function of the heat storage panel 4.

Next, refer to Figures 4 and 5. Figure 4 is an enlarged schematic view of part A in Figure 3; Figure 5 is a partial structural schematic view of the heat storage panel in an embodiment of the present invention under a top view. The solid circle in the figure represents For the first air passage, the dashed circle represents the second air passage, and the double dashed line represents the first partition.

As shown in Figures 4 and 5, in a preferred embodiment, the panel body includes a first plate body 411 and a second plate body 412, and a heat storage is formed between the first plate body 411 and the second plate body 412. In the cavity 44, the first plate body 411 is provided with a plurality of first air passage holes 421, the second plate body 412 is provided with a plurality of second air passage holes 422, and the first air passage holes 421 and the second air passage holes At least a part of 422 is not aligned in the direction of the wind. With this arrangement, after the wind enters the heat storage cavity 44 through the first air passage 421, at least a part of the wind will not directly enter the indoor space through the second air passage 422, but will be affected by the second plate 412. Block, thereby forming a vortex in the heat storage cavity 44.

Further, the first air passage holes 421 and the second air passage holes 422 are staggered along the direction of the wind. With this arrangement, all the wind entering the heat storage cavity 44 through the first air passage hole 421 can be blocked by the second plate 412, so that more wind stays in the heat storage cavity 44, and the formation is enlarged. The eddy current further improves the heat storage effect of the heat storage panel 4.

Further, a partition assembly is provided between the first plate body 411 and the second plate body 412, and the partition assembly can form a plurality of independent heat storage cavities 44 between the first plate body 411 and the second plate body 412. In this way, a plurality of independent heat storage spaces are formed in the panel body, and the wind entering the panel body can form a plurality of vortices in an orderly manner and without interference.

The structure of the partition assembly can have many forms. For example, in a preferred embodiment, as shown in Figures 3, 4 and 5, the partition assembly includes a plurality of first partitions arranged at intervals along the width direction of the panel body. 431, so that a plurality of independent thermal storage cavities 44 distributed along the width direction of the panel body are formed between the first plate body 411 and the second plate body 412. A plurality of first air passage holes 421 are distributed along the length direction of the first plate 411 at a position corresponding to each heat storage cavity 44 of the first plate 411. A plurality of second air passage holes 422 are distributed along the length direction of the second plate body 412 at positions corresponding to each heat storage cavity 44 of the second plate body 412, and the first air passage holes 421 and the second air passage holes 422 Staggered along the wind direction.

The air outlet process of the heat storage panel 4 is as follows: when the wind enters the heat storage panel 4, it will first pass through the first air passage 421 on the first plate 411 to form a breeze and enter the corresponding heat storage cavity 44. The second air passage holes 422 of the plate body 412 and the first air passage holes 421 of the first plate body 411 are arranged in a staggered arrangement. The breeze did not complete the wind at the first time, but formed a vortex in each heat storage cavity 44. A number of small energy circles are formed to complete the heat storage function of the panel. After the airflow accumulates to a certain volume in the heat storage cavity 44, the airflow in the heat storage cavity 44 moves to both sides under the pressure of the subsequent airflow, and enters the indoor space through the second air passage.

Next, refer to Figure 6, Figure 7 and Figure 8, where Figure 6 is a flow diagram of the first air outlet of the heat storage panel in an embodiment of the present invention; Figure 7 is an embodiment of the present invention The air outlet flow line diagram of the second air passing hole of the middle heat storage panel; FIG. 8 is the air outlet flow line diagram of the first air passing hole and the second air passing hole of the heat storage panel in an embodiment of the present invention.

As shown in Figs. 6 and 8 and according to the orientation of Fig. 8, when wind passes through the first air passing hole 421 on the first plate body 411, a vortex is formed in each heat storage cavity 44 of the heat storage panel 4, And the speed of the airflow entering the first air passing hole 421 is uniform. After the air flow accumulates to a certain volume in the heat storage chamber 44, under the pressure of the air flow entering the heat storage chamber 44, the air flow in the heat storage chamber 44 moves to both sides and passes through the second plate on the second plate 412. The wind hole 422 completes the wind. In this process, referring to FIG. 7, the air outlet velocity of the second air passage hole 422 on the second plate 412 is uniform.

It can be seen that through the arrangement of the first partition 431, multiple independent heat storage regions can be formed in the heat storage panel 4, thereby improving the heat storage capacity of the heat storage panel 4. By staggering the first air passing holes 421 and the second air passing holes 422 along the air outlet direction, the airflow can stay in the panel body and form a vortex in the heat storage cavity 44. The uniform distribution of the two air passing holes 422 can make the air out of the heat storage panel 4 more uniform. In addition, both sides of the heat storage panel 4 are provided with air holes, which can make the wind speed softer and the wind direction more stable; on the other hand, it can also effectively prevent the heat storage panel 4 from flowing back after the wind is discharged. This phenomenon can continuously deliver moderate and soft wind to the room, thereby improving the comfort of room cooling and heating.

It should be noted that although the above example uses the panel body as a double-layer board as an example to illustrate the structure of the heat storage panel of the present invention, it should be noted that in practical applications, the panel body is not limited to the double-layer board. , It can also be a three-layer board or more. When the panel body is a structure with more than two layers of panels, a heat storage cavity 44 is formed between the adjacent panels of the panel body, and each panel is provided with a through hole, and the adjacent panel At least a part of the air passage holes are not aligned, so that after the wind enters the heat storage cavity 44 through the air passage holes of the upstream side plate, it will be blocked by the downstream side plate and form a vortex in the heat storage cavity 44. Those skilled in the art can reasonably set the structure of the panel body according to the actual situation.

In addition, in practical applications, the arrangement of the partition component is not necessary. For example, in some possible implementations, the partition component may not be provided. In the case of the partition assembly, the arrangement form of the partition assembly is not limited to the above examples. For example, the partition assembly may also include a plurality of second partitions arranged at intervals along the width direction of the panel body, or the partition assembly includes a plurality of partitions along the panel. The first plate 411 spaced apart in the longitudinal direction of the main body and a plurality of second plates 412 spaced apart in the width direction of the panel main body. Those skilled in the art can flexibly adjust whether to provide a partition component and the specific form of the partition component when the partition component is provided according to the actual situation.

Further, the aperture of the first air passage hole 421 is larger than the aperture of the second air passage hole 422. Through this arrangement, the vortex in the heat storage cavity 44 can be increased, thereby improving the heat storage function of the heat storage panel 4, and can make the wind finally blown out from the second air passage 422 softer, and furthermore Prevent the backflow phenomenon of the wind from the heat storage panel 4.

Further, at least a part of the first plate body 411, the second plate body 412 and the partition assembly are connected in a detachable manner. As in a possible implementation manner, the second plate body 412 and the partition assembly are an integral structure to form a toothed plate, and the first plate body 411 is a flat plate, and the flat plate and the toothed plate are connected to each other by screw fixing. Of course, the flat plate and the toothed plate can also be connected to each other in other possible ways such as clamping, glue bonding and the like. Moreover, in practical applications, the first plate body 411 and the partition assembly may also be designed as an integrated structure to form a toothed plate, and the second plate body 412 is a flat plate.

The advantage of the above arrangement is that by designing the panel body as a toothed plate and a flat plate that are detachably connected to each other, on the one hand, it is convenient to process, and on the other hand, it is also convenient to realize the assembly and disassembly of the panel body, thereby improving the convenience of disassembly and assembly. It is understandable that the structure of the above-mentioned panel body is not limited to the form of the flat plate and the tooth-shaped plate connected to each other in the above example, it can also be other possible structures, and those skilled in the art can make reasonable decisions based on actual needs. Set up.
