DETAILED DESCRIPTION

[0026] The present invention will be further described below with reference to the accompanying drawings.

[0027] according to Figure 1-Figure 2As shown, the embodiment of the present application proposes a composite air supply structure, including an air conditioner main body 1, the air conditioner main body 1 is provided with an air outlet 6, and the air outlet 6 is movably provided with a main swing blade 3 for guiding air to the outside; the lower end of the air conditioner main body 1 is provided with an auxiliary air supply mechanism 2, and the auxiliary air supply mechanism 2 is used to receive part or all of the air volume generated by the air conditioner main body 1 and send out the received air volume; the auxiliary air supply mechanism 2 includes a shell 4 provided on the air conditioner main body 1, and the shell 4 is movably provided with an external swing blade 5, and the external swing blade 5 is used to control the connection and isolation between the air duct of the air conditioner main body 1 and the shell 4, and the shell 4 is also provided with an air guide component for controlling the air flow to be guided in different directions. The auxiliary air supply mechanism 2 can cooperate with the adjustment of the main swing blade 3 to realize the joint operation of the air outlet 6 of the air conditioner and the air guide component of the auxiliary air supply mechanism 2, thereby achieving more air outlet angles and air volume adjustment effects, thereby improving the user's experience of the air conditioner. When auxiliary air supply is required, the main airflow is cut to the auxiliary air supply mechanism 2 to realize the partitioned delivery requirements of the main airflow and the secondary air supply airflow, and the airflow delivery is effectively divided according to the rotation angle of the external swing blade 5; and the setting of the shell 4 can effectively extend the volute profile of the lower part of the air duct, thereby improving the main air supply volume and air supply distance of the air conditioner.

[0028] First of all, it should be stated that the above-mentioned air-conditioning main body 1 includes a middle frame 7, a cross-flow fan 9 is arranged in the middle frame 7, and a heat exchanger assembly 8 is arranged around the cross-flow fan 9. The cross-flow fan 9 sends air into the air duct by rotating, and a sweeping structure 10 is provided in the air duct, which can realize the normal left and right sweeping process of the wall-mounted air conditioner. The above-mentioned air duct is connected to the air outlet 6, and the main swing blade 3 is controlled by the drive system to adjust the opening size and the air outlet angle of the air outlet 6. By adjusting the shape of the external swing blade 5, it is ensured that part or all of the wind sent out from the air outlet 6 enters the interior of the shell 4, and the air flow entering the shell 4 is guided outward to different directions through the air guide assembly to optimize the air outlet pattern.

[0029] like Figure 3-5 As shown, the main swing blade 3 and the external swing blade 5 are respectively located on both sides of the air outlet 6, and one side of the shell 4 extends to the position of the main swing blade 3. When the main swing blade 3 is swung to the closed position, the main swing blade 3 and the outer shell 4 cooperate to prevent the airflow from being directly discharged outward from the air outlet 6. When the main swing blade 3 rotates to one side to seal the air outlet 6, the other side contacts the outer shell 4, forming a closed effect of the air outlet 6, and the airflow cannot be discharged from the air outlet 6 to the outside. By adjusting the external swing blade 5, the air outlet 6 and the inside of the shell 4 are connected, thereby improving the sealing and stability of the overall structure.

[0030] It is worth noting that when the above-mentioned external swing blade 5 is opened to the extreme position, the external swing blade 5 blocks about half of the air outlet 6. At this time, the main swing blade 3 is fully opened, and the air volume directly discharged from the air outlet 6 is almost the same as the air volume entering the shell 4. In other words, the primary air outlet of the air-conditioning main body 1 and the secondary air outlet of the auxiliary air outlet mechanism have the same air volume, and the secondary air outlet can have more angles and directions, ensuring the all-round and stable air outlet effect of the air conditioner.

[0031] In addition, the above-mentioned external swing blade 5 is an arc-shaped plate, and when the above-mentioned external swing blade 5 completely isolates the inner cavity of the above-mentioned shell 4, the above-mentioned external swing blade 5 forms a part of the air duct of the air-conditioning main body 1 and extends to the above-mentioned air outlet 6 position. When the main swing blade 3 swings to the point where the air flow can be discharged to the outside through the air outlet 6, the external swing blade 5 closes the air outlet 6 and the inner cavity of the shell 4 at this time, thereby achieving maximum air volume improvement without increasing the overall thickness.

[0032] Regarding the above-mentioned air guide assembly, specifically, the above-mentioned air guide assembly includes two groups of air guide fan units symmetrically arranged in the above-mentioned shell 4, and the above-mentioned outer shell is provided with an air outlet frame assembly at a position corresponding to the above-mentioned air guide fan unit. The above-mentioned air guide fan unit is used to send the airflow entering the above-mentioned shell 4 out from the above-mentioned air outlet frame assembly. The two groups of air guide fan units are stacked in the length direction of the shell 4, and the center of the line connecting the two groups of air guide fan units coincides with the midpoint of the length of the shell 4. That is to say, the two groups of air guide fan units can respectively achieve the air guiding effect on both sides of the midpoint in the length direction of the shell 4, and the air outlet effect is more uniform. The air guide frame assembly is specifically a protective shell with air holes arranged at positions corresponding to the two air guide fan units on the periphery of the shell 4 to ensure a stable air outlet effect.

[0033] like Figure 6 、 Figure 7 As shown, the above-mentioned guide fan unit includes a centrifugal fan 11 arranged in the above-mentioned shell 4, and an air duct assembly connected to the above-mentioned air outlet frame assembly is arranged around the circumference of the above-mentioned centrifugal fan 11. The above-mentioned air outlet frame assembly includes a front air outlet frame 16 and a side air outlet frame 17 respectively arranged on both sides of the above-mentioned centrifugal fan 11. The two front air outlet frames 16 corresponding to the two above-mentioned centrifugal fans 11 are close to each other, and the two side air outlet frames 17 corresponding to the two above-mentioned centrifugal fans 11 are far away from each other. An adjustment assembly is provided in the above-mentioned air duct, and the above-mentioned adjustment assembly is used to adjust the flow direction of the airflow in the air duct assembly. When working, the above-mentioned adjustment assembly is adjusted to only connect to the front air outlet frame 16 or the side air outlet frame 17 or to connect to the front air outlet frame 16 and the side air outlet frame 17 at the same time; that is, the airflow entering the shell 4 through the air outlet 6 is guided to the air duct assembly on the left and right sides of the centrifugal fan 11 and is exported from the air outlet frame assembly.

[0034] Specifically, when the above-mentioned adjustment component is adjusted to allow air to be discharged only from the front air outlet frame 16, the two front air outlet frames 16 are adjacent and close to each other, and are both located in the middle of the shell 4. At this time, the front air outlet effect can be guaranteed. When the adjustment component is adjusted to allow air to be discharged from the side air outlet frame 17, the two side air outlet frames 17 are located on both sides of the shell 4 to achieve the side air outlet effect.

[0035] The above-mentioned adjustment component includes a semicircular arc baffle 15 rotatably set on the above-mentioned shell 4, and the above-mentioned arc baffle 15 is arranged around the outside of the corresponding centrifugal fan 11. The above-mentioned air duct component includes a first air duct 18 and a second air duct 19. The above-mentioned first air duct 18 and the above-mentioned second air duct 19 are respectively connected to the front air outlet frame 16 and the side air outlet frame 17 on the side of the corresponding centrifugal fan 11; when the arc baffle 15 is rotated to the side close to the above-mentioned front air outlet frame 16, the airflow can only be discharged from the side air outlet frame 17; when the arc baffle 15 is rotated to the side close to the above-mentioned side air outlet frame 17, the airflow can only be discharged from the side air outlet frame 17; when the arc baffle 15 is rotated to other positions, the airflow is discharged from the side air outlet frame 17 and the front air outlet frame 16 at the same time.

[0036] During operation, the arc-shaped baffle 15 is driven to rotate by the air-conditioning driving system. When the arc-shaped baffle 15 rotates to close the first air duct 18, it is in a side air outlet effect. When the arc-shaped baffle 15 closes the second air duct 19, it is in a front air outlet effect. When the arc-shaped baffle 15 does not completely close the first air duct 18 and the second air duct 19, the first air duct 18 and the second air duct 19 are allowed to take in air at the same time, achieving the effect of the front air outlet frame 16 and the side air outlet frame 17 discharging air at the same time. Moreover, the size of the front air outlet and the side air outlet can be adjusted by adjusting the size of the air intake of the first air duct 18 and the second air duct 19 at the same time, thereby improving the user's choice of air outlet mode and improving the user experience.

[0037] In order to ensure that the shell 4 has sufficient sealing performance, a sealing baffle 12 is provided in the shell 4. The sealing baffle 12 is located between the air-conditioning main body 1 and the guide fan unit, and the sealing baffle 12 is provided with an air inlet corresponding to the position of the guide fan unit to ensure that the airflow entering the shell 4 from the air outlet 6 can be fully utilized and discharged without gas leakage and loss.

[0038] Moreover, an air inlet cavity 13 is formed on the upper portion of the sealing baffle 12, and the external swing blade 5 can connect the air outlet 6 and the air inlet cavity 13 by rotating. By setting the air inlet cavity 13, it is possible to achieve mixing of the non-cooling and heating indoor air flow and the air conditioning cooling and heating air flow to a certain extent, and the air supply direction is adjusted by the guide fan unit to achieve multi-angle mixed air flow delivery.

[0039] At the same time, an insulation layer 14 is provided in the shell 4, which can effectively improve the temperature of the air flow entering the auxiliary air supply mechanism 2 to achieve insulation, and avoid as much as possible the air flow entering the shell 4 to cause heat exchange and change in the air flow temperature, thereby ensuring the accuracy of the overall temperature control of the air conditioner.

[0040] The embodiment of the present application also proposes an air conditioner, including the above-mentioned composite air supply structure. The air conditioner is realized through the composite air supply structure, and the air supply options for different users are optimized to achieve the effect of multi-angle coverage air supply.

[0041] In summary, the present invention proposes a composite air supply structure, comprising an air-conditioning main body 1, the air-conditioning main body 1 is provided with an air outlet 6, and the air outlet 6 is movably provided with a main swing blade 3 for guiding air to the outside; an auxiliary air supply mechanism 2 is provided at the lower end of the air-conditioning main body 1, and the auxiliary air supply mechanism 2 is used to receive part or all of the air volume generated by the air-conditioning main body 1 and send out the received air volume; the auxiliary air supply mechanism 2 comprises a shell 4 arranged on the air-conditioning main body 1, and the shell 4 is movably provided with an external swing blade 5, and the external swing blade 5 is used to control the connection and isolation between the air duct of the air-conditioning main body 1 and the shell 4, and the shell 4 is further provided with an air guide component for controlling the air flow to be guided in different directions; the overall structure can be realized The cooling and heating airflow of the air conditioner is transported secondary at multiple angles and in multiple directions; the air duct line is formed in conjunction with the main air conditioner, and the air supply distance and air volume are increased when a large air volume is required. When a secondary air supply is required, the main airflow is cut to the auxiliary air supply mechanism 2, so as to realize the partitioned transport requirements of the main airflow and the auxiliary air supply airflow, and the airflow transport is effectively divided according to the rotation angle of the external swing blade 5. When the air volume demand of the air conditioner main body 1 is large, the volute profile of the lower part of the air duct can be effectively extended, thereby improving the main air supply volume and air supply distance of the air conditioner (the actual test air volume can be effectively increased by 5%); the setting of the arc baffle 15 can stably and accurately adjust the air supply angle and air supply volume of the auxiliary air supply mechanism 2.
