[0045] The embodiment provides a kind of air conditioner box blowing structure, the air conditioner box blowing structure will not have cold air flow from left middle air outlet and right middle air outlet of air outlet piece blow out, solve the problem of cold air flow leakage that air conditioning system still has cold air flow blowing to human face when in non-blow mode.

[0046] Specifically, as Figures 1 to 7As shown, the air conditioning unit's air blowing structure includes an air box assembly, an air outlet 200, and a blowing damper assembly 300. The air box assembly includes a first distribution box 110 and a second distribution box 120 arranged in sequence; the air outlet 200 is fixed to one side of the air box assembly, and along the direction from the first distribution box 110 to the second distribution box 120 (from left to right in the figure), a left air outlet 210, a left-middle air outlet 220, a right-middle air outlet 230, and a right air outlet 240 are arranged in sequence, wherein the left air outlet 210 and the left-middle air outlet 220 are opposite to the outlet of the first distribution box 110, and the right air outlet 240 and the right-middle air outlet 230 are opposite to the outlet of the second distribution box 120. The blowing damper assembly 300 is located between the air box assembly and the air outlet 200. The blowing damper assembly 300 includes a door body 310 and two dampers 320. The two ends of the door body 310 are rotatably connected to the first distribution box 110 and the second distribution box 120, respectively. The two dampers 320 are arranged opposite to each other on one side of the door body 310. Each of the two dampers 320 on the opposite side of the door body 310 is provided with an air leakage port 311. The door body 310 can rotate to block the outlet of the first distribution box 110 and the outlet of the second distribution box 120. One of the dampers 320 abuts against the part between the left air outlet 210 and the left middle air outlet 220 to cut off the connection between the left air outlet 210 and the left middle air outlet 220. The other damper 320 abuts tightly against the right air outlet 240 and the right middle air outlet 230 to cut off the connection between the right air outlet 240 and the left air outlet 210. This allows the cold air flow of the first distribution box 110 to be discharged only through the corresponding air vent 311 and the left air outlet 210 in sequence, and the cold air flow of the second distribution box 120 to be discharged only through the other corresponding air vent 311 and the right air outlet 240.

[0047] It should be noted that, Figure 5 and Figure 7 In the image, the multiple arrows point in the direction of the cold airflow.

[0048] Based on the above design, the first distribution box 110 provides cold airflow to the left air outlet 210 and the left center air outlet 220, and the second distribution box 120 provides cold airflow to the right center air outlet 230 and the right air outlet 240. When the air conditioning system is on and not in face-blowing mode, the door body 310 can rotate to block the outlets of the first distribution box 110 and the second distribution box 120, i.e. Figure 4 and Figure 5As shown, the face-blowing damper assembly 300 is in the closed state, and one damper 320 abuts against the portion between the left air outlet 210 and the left middle air outlet 220 to cut off the connection between the left air outlet 210 and the left middle air outlet 220. The other damper 320 abuts tightly against the right air outlet 240 and the right middle air outlet 230 to cut off the connection between the right air outlet 240 and the left air outlet 210. This ensures that the cold airflow from the first distribution box 110 can only be blown out sequentially through the corresponding air vent 311 and the left air outlet 210, and the cold airflow from the second distribution box 120 can only be blown out through the other corresponding air vent 311 and the right air outlet 240. That is, no cold airflow will be blown out from the left middle air outlet 220 and the right middle air outlet 230, thus solving the problem that the air conditioning system still blows air onto the human face when it is not in face-blowing mode.

[0049] It should be noted that when the air conditioning system is turned on and in face-blowing mode, the door body 310 can rotate to open the outlet of the first distribution box 110 and the outlet of the second distribution box 120, i.e. Figure 6 and Figure 7 As shown, the face-blowing damper assembly 300 is in the open state, allowing the cold airflow from the first distribution box 110 to enter the left air outlet 210 and the left-middle air outlet 220 of the air outlet 200, respectively, and the cold airflow from the second distribution box 120 to enter the right air outlet 240 and the right-middle air outlet 230 of the air outlet 200, respectively. That is, when the air conditioning system is turned on and in face-blowing mode, there is a gap between one damper 320 and the left air outlet 210 and the left-middle air outlet 220, allowing the left air outlet 210 and the left-middle air outlet 220 to connect; there is also a gap between the other damper 320 and the right air outlet 240 and the right-middle air outlet 230, allowing the right air outlet 240 and the left air outlet 210 to connect.

[0050] Furthermore, the side of the door body 310 away from the damper 320 can seal the outlet of the first distribution box 110 and the outlet of the second distribution box 120, preventing the cold air flow of the first distribution box 110 and the second distribution box 120 from flowing out through the gap between the bellows assembly (first distribution box 110 and second distribution box 120) and the door body 310 and being lost.

[0051] Optionally, such as Figures 8 to 14As shown, the blowing damper assembly 300 also includes a sealing sheet 330 and two sealing strips 340. The sealing sheet 330 is attached to the side of the door body 310 away from the damper 320. The two sealing strips 340 are respectively located at the edge of the two dampers 320 away from the door body 310. That is, the air box assembly and the door body 310 are sealed by the sealing sheet 330, and the damper 320 and the air outlet 200 are sealed by the sealing strips 340. When the blowing damper assembly 300 is closed, it can form an interference fit between the air box assembly and the door body 310 and between the damper 320 and the air outlet 200, so as to achieve a sealing effect and solve the problem of cold air leakage.

[0052] Furthermore, the door body 310 and the two dampers 320 are integrally formed, making processing simple and convenient; the sealing sheet 330 and the two sealing strips 340 are also integrally formed, that is, the sealing sheet 330 and the two sealing strips 340 are wrapped around the outside of the door body 310 and the dampers 320.

[0053] In this embodiment, the blowing air damper assembly 300 is an integral blowing air damper assembly 300 formed by two-color mold injection molding or secondary injection molding. Although it is a single part, it contains both hard plastic material and soft rubber material. That is, the door body 310 and the two air dampers 320 are made of hard plastic material, while the sealing sheet 330 and the two sealing strips 340 are made of soft rubber material.

[0054] Optionally, one of the damper 320 and the sealing strip 340 is provided with a groove, and the other is provided with a protrusion. The shapes of the groove and the protrusion are adapted to each other, and the protrusion is inserted into the groove. The sealing strip 340 is engaged with the damper 320, which can not only increase the sealing performance of the damper 320 and the sealing strip 340, but also position the sealing strip 340 during installation and prevent the sealing strip 340 from being squeezed out.

[0055] In this embodiment, the groove is provided on the damper 320, and the protrusion is provided on the sealing strip 340.

[0056] Optionally, the air conditioning unit's air blowing structure is also provided with two door stops 400, each corresponding to a sealing strip 340. The two door stops 400 are located between the left air outlet 210 and the left middle air outlet 220, and between the right air outlet 240 and the right middle air outlet 230, respectively. The two ends of the door stops 400 abut against the corresponding sealing strip 340 and the air outlet component 200, respectively. When the distance between the air outlet component 200 and the air box assembly is constant, setting the door stops 400 can reduce the size of the damper 320 and prevent the damper 320 from being too large. When the air blowing damper assembly 300 is opened, the door body 310 rotates, causing the damper 320 to rotate, thus preventing the damper 320 from occupying space.

[0057] In this embodiment, both the sealing strip 340 and the door stop 400 are involute shapes, and the sealing strip 340 and the door stop 400 have good sealing effects.

[0058] It should be noted that when the blowing air damper assembly 300 is in the open state, there is a gap between one damper 320 and the door stop 400, allowing the left air outlet 210 and the left center air outlet 220 to connect; there is also a gap between the other damper 320 and the other door stop 400, allowing the right air outlet 240 and the left air outlet 210 to connect, thus making the operation of the blowing air damper assembly 300 smoother during rotation. When the blowing air damper assembly 300 is in the closed state (fully closed), one damper 320 and the door stop 400 are interference-fitted; the other damper 320 and the other door stop 400 are also interference-fitted. That is, during the closing process of the blowing air damper assembly 300, the gap between the involute damper 320 and the involute door stop 400 will gradually decrease, eventually forming an interference fit, achieving a sealing effect, thereby solving the problem of cold air leakage. This embodiment also provides an air conditioning system that solves the problem of cold air leakage when cold air still blows onto the human face in non-face-blowing mode.

[0059] Specifically, the air conditioning system includes an air conditioner body and the aforementioned air conditioning box blowing structure. The cold air flow generated by the air conditioner body is blown out through the air conditioning box blowing structure. The first distribution box 110 provides cold air flow to the left air outlet 210 and the left center air outlet 220, and the second distribution box 120 provides cold air flow to the right center air outlet 230 and the right air outlet 240. When the air conditioning system is turned on and not in face-blowing mode, the door body 310 can rotate to block the outlets of the first distribution box 110 and the second distribution box 120. One of the dampers 320 abuts against the portion between the left air outlet 210 and the left middle air outlet 220 to cut off the connection between the left air outlet 210 and the left middle air outlet 220. The other damper 320 abuts tightly against the right air outlet 240 and the right middle air outlet 230 to cut off the connection between the right air outlet 240 and the left air outlet 210. This ensures that the cold airflow from the first distribution box 110 can only be blown out through the corresponding air vents 311 and the left air outlet 210 in sequence, and the cold airflow from the second distribution box 120 can only be blown out through the other corresponding air vent 311 and the right air outlet 240. In other words, no cold airflow will be blown out from the left middle air outlet 220 and the right middle air outlet 230, thus solving the problem that the air conditioning system still blows air onto the human face when it is not in face-blowing mode.

[0060] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
