The first fan 30 assembly includes a first fan 30, and the second fan 40 assembly includes a second fan 40. One end of the baffle structure 50 is connected to the first fan 30 assembly and the second fan 40 assembly, and the other end of the baffle structure 50 is in contact with the evaporator 20 or has a preset gap, so as to separate the area between the evaporator 20, the first fan 30 and the second fan 40 into a first area 1 and a second area 2. Among them, at least part of the position of the baffle structure 50 is adjustable to adjust at least part of the position of the baffle structure 50 according to the first rotational speed of the first fan 30 and the second rotational speed of the second fan 40 to adjust the volume of the first area 1 and the second area 2.

[0049] Applying the technical solution of this embodiment, the air conditioning device includes a housing 10, a first air outlet 11, a second air outlet 12, an evaporator 20, a first fan 30 assembly, a second fan 40 assembly and a baffle structure 50. The evaporator 20 is arranged in the housing 10. The first fan 30 assembly and the second fan 40 assembly are both arranged in the housing 10, and the first fan 30 assembly and the second fan 40 assembly are arranged in sequence along a first preset direction. The first fan 30 assembly includes a first fan 30, and the second fan 40 assembly includes a second fan 40. One end of the baffle structure 50 is connected to the first fan 30 assembly and the second fan 40 assembly, and the other end of the baffle structure 50 is in contact with the evaporator 20 or has a preset gap, so as to separate the area between the evaporator 20, the first fan 30 and the second fan 40 into a first area 1 and a second area 2. Among them, at least part of the position of the baffle structure 50 is adjustable, so that at least part of the position of the baffle structure 50 can be adjusted according to the first rotation speed of the first fan 30 and the second rotation speed of the second fan 40, so as to adjust the volume of the first area 1 and the second area 2. In this way, the air conditioning device blows gas from the first air outlet 11 through the first fan 30 and blows gas from the second air outlet 12 through the second fan 40, thereby realizing the requirement of the air conditioning device to supply air to people in different areas, realizing the requirement of the air conditioning device to blow wind of different intensities to different areas, meeting the use needs of different users, and improving the versatility and multifunctionality of the air conditioning device. At the same time, when the first fan 30 and the second fan 40 in the double cross-flow air conditioner are running at different rotation speeds, at least part of the position of the baffle structure 50 can be adjusted accordingly, so that the contact area between the evaporator 20 and the gas is adjusted accordingly, ensuring the uniformity of the wind field of the evaporator 20, thereby ensuring the uniformity of the heat exchange of the evaporator 20, and thus solving the problem of poor uniformity of the heat exchange of the evaporator 20 in the double cross-flow air conditioner in the prior art. At the same time, the above-mentioned setting of the baffle structure 50 can also separate the first fan 30 and the second fan 40, avoid interference between the first fan 30 and the second fan 40 during operation, reduce the noise during operation of the first fan 30 and the second fan 40, and improve the user comfort.

[0050] In this embodiment, the first air outlet 11 and the second air outlet 12 are both disposed on the housing 10 .

[0051] like Figure 2 As shown, the first preset direction is Figure 2 Horizontal direction.

[0052] In one embodiment, the first fan 30 assembly further includes a first volute, the second fan 40 assembly further includes a second volute, and the baffle structure 50 includes a fixed portion 51 and a free portion 52. The fixed portion 51 is connected to the first volute and the second volute, respectively. The free portion 52 is rotatably arranged along a predetermined rotation axis to adjust the volume of the first region 1 and the second region 2 by controlling the position of the free portion 52. In this way, the baffle structure 50 is connected to the first fan 30 assembly and the second fan 40 assembly through the fixed portion 51, and adjusts its own position through the rotation of the free portion 52, thereby ensuring the reliability of the position adjustment of the baffle structure 50, thereby ensuring the uniformity of the wind field of the evaporator 20, and ensuring the energy saving of the air conditioning device.

[0053] In another embodiment, the first fan 30 assembly further includes a first volute, the second fan 40 assembly further includes a second volute, and the baffle structure 50 includes a fixed portion 51 and a free portion 52. The fixed portion 51 is connected to the first volute and the second volute, respectively. At least a portion of the free portion 52 is movably arranged along a first preset direction of the first fan 30 and the second fan 40, so as to adjust the volume of the first area 1 and the second area 2 by controlling at least a portion of the position of the free portion 52.

[0054] like Figure 2 As shown, the predetermined rotation axis is the central axis of the fixed portion 51. Thus, the above arrangement ensures the stability and smoothness of the rotation of the free portion 52, ensures the smoothness of the position adjustment of the baffle structure 50, and further ensures the uniformity of the wind field of the evaporator 20.

[0055] In this embodiment, the fixing portion 51 is a centrosymmetric structure.

[0056] like Figure 2 As shown, the evaporator 20 is a symmetrical structure relative to the predetermined plane, and the first fan 30 and the second fan 40 are symmetrically arranged relative to the predetermined plane. Along the direction having an angle with the first preset direction, the baffle structure 50 has a starting position. When the baffle structure 50 is in the starting position, the baffle structure 50 is symmetrically arranged relative to the predetermined plane so that the volumes of the first area 1 and the second area 2 are equal. In this way, the above arrangement ensures the structural stability and symmetry between the evaporator 20, the first fan 30 and the second fan 40, improves the uniformity of the distribution of the wind field, and is also conducive to improving the air outlet efficiency and heat exchange efficiency of the air conditioning device.

[0057] In this embodiment, the evaporator 20 is a C-shaped structure to further increase the heat exchange area of ​​the evaporator 20 .

[0058] like Figure 2 As shown, the predetermined plane is a cross section perpendicular to the axial direction of the air conditioning device.

[0059] In this embodiment, along a direction perpendicular to the first preset direction, the baffle structure 50 has a starting position.

[0060] Specifically, the air conditioning device further includes a detection component. The detection component is disposed on the housing 10 to detect the distance between the user and the air conditioning device, so as to adjust the first speed and the second speed according to the distance. In this way, the detection component can detect the distance between the user and the air conditioning device in real time, so that the air conditioning device can adjust the first speed and the second speed in real time according to the distance between the user and the air conditioning device, so that the user can get a better blowing experience at different positions, thereby improving the user's comfort and also improving the degree of automation and versatility of use of the air conditioning device.

[0061] In this embodiment, the detection component is a millimeter wave radar device.

[0062] Specifically, the air conditioning device further includes a display structure 80 , which is disposed on the housing 10 ; wherein the detection component is disposed in the display structure 80 .

[0063] The present application also provides a method for controlling an air conditioning device, which is applicable to the above-mentioned air conditioning device, such as Figure 8 As shown, the air conditioning device control method includes:

[0064] S100, obtaining a first rotation speed of a first fan 30 and a second rotation speed of a second fan 40 of the air conditioning device.

[0065] S200, adjusting the position of at least a portion of the baffle structure 50 of the air conditioning device according to the first rotation speed and the second rotation speed to adjust the volumes of the first area 1 and the second area 2 of the air conditioning device.

[0066] In this way, the above-mentioned setting enables the baffle structure 50 to adjust its own position in real time according to the difference between the first rotational speed and the second rotational speed, so that the volume of the first area 1 and the second area 2 can be adjusted in real time, ensuring that the air-conditioning device meets the needs of different users while ensuring the uniformity of the wind field of the evaporator 20, thereby improving the heat exchange efficiency and heat exchange uniformity of the evaporator 20.

[0067] like Figure 7As shown, the method for obtaining the first rotation speed of the first fan 30 and the second rotation speed of the second fan 40 includes: obtaining the air supply mode of the air supply area corresponding to the fan. Obtaining the minimum distance between the air conditioner and the user of the air supply area. Determining the rotation speed according to the air supply mode and the minimum distance of the air supply area. Among them, the fan is the first fan 30 or the second fan 40, the air supply area is the first air supply area 3 or the second air supply area 4, the minimum distance is the first minimum distance or the second minimum distance, the rotation speed is the first rotation speed or the second rotation speed, the first rotation speed is determined according to the air supply mode and the first minimum distance of the first air supply area 3, and the second rotation speed is determined according to the air supply mode and the second minimum distance of the second air supply area 4. In this way, the above setting enables the first rotation speed to be adjusted according to the air supply mode of the first air supply area 3, and also according to the first minimum distance between the user and the user, which meets the use needs of the users in the first air supply area 3, so that the air conditioner can not only meet the use needs of different users, but also adjust the air volume according to the activity state of the user, improve the diversity and flexibility of the air blowing of the air conditioner, and further improve the user's use experience.

[0068] Optionally, the user sets the air supply modes of the first air supply area 3 and the second air supply area 4 through a mobile phone program or a remote controller or other device.

[0069] In this embodiment, the user connects to the air conditioner via Bluetooth via a mobile phone program.

[0070] Specifically, according to the air supply mode and the minimum distance of the air supply area, the formula for determining the rotation speed is:

[0071] N = (L-1) x X + Y.

[0072] Wherein, N is the rotation speed, L is the minimum distance, X is a preset coefficient, there are multiple preset coefficients X, and the multiple preset coefficients X are set in one-to-one correspondence with the multiple air supply modes of the air supply area. When the air supply area is in each air supply mode, the rotation speed N is calculated according to the corresponding preset coefficient X. Y is a preset value, there are multiple preset values ​​Y, and the multiple preset values ​​Y are set in one-to-one correspondence with the multiple air supply modes of the air supply area. When the air supply area is in each air supply mode, the rotation speed N is calculated according to the corresponding preset value Y. In this way, the above setting provides a calculation basis for the first rotation speed, ensures that the first rotation speed of the first fan 30 in different air supply modes and different first minimum distances is calculated, ensures the operation accuracy of the first fan 30, and also ensures the air supply accuracy of the air conditioning device.

[0073] In this embodiment, there are multiple users in the air supply area, and the minimum distance is the distance between the air conditioning device and a user who is closest to the air conditioning device.

[0074] Specifically, the multiple air supply modes of the air supply area include a first mode and a second mode. When the air supply area is obtained to be in the first mode, X is 150 and Y is 500. When the air supply area is obtained to be in the second mode, X is 50 and Y is 200. In this way, the above settings of X and Y make it so that when the air supply mode of the first air supply area 3 is in the first mode, the first speed of the first fan 30 is higher to meet the needs of users who need a larger air volume; when the air supply mode of the first air supply area 3 is in the second mode, the first speed of the first fan 30 is lower to meet the needs of users who have less demand for air volume, further ensuring the air supply accuracy of the air conditioning device.

[0075] In this embodiment, the first mode is the wind-friendly mode, and the second mode is the windless mode.

[0076] In this embodiment, the unit of N is r / min.

[0077] Specifically, if 1<L≤2, L is 2; if 5≤L, L is 6. In this way, the above setting limits the specific value of L, which is convenient for calculation and reduces the number of times the air conditioner adjusts the first speed and the second speed, thereby avoiding damage to the first fan 30 and the second fan 40 due to too many adjustments, thereby extending the service life of the first fan 30 and the second fan 40 and the service life of the air conditioner.

[0078] Specifically, the method for obtaining the minimum distance between the air conditioner and the user in the air supply area includes: using the detection component of the air conditioner to detect the real-time distance between the air conditioner and the user in the air supply area, wherein the real-time distance is the minimum distance. In this way, the air conditioner detects the real-time distance between the user and the air conditioner in real time through the detection component, thereby ensuring the timeliness and accuracy of the air conditioner obtaining the real-time distance, thereby ensuring the accuracy of the air supply of the fan, and further improving the user's comfort.

[0079] like Figures 3 to 5As shown, according to the first rotation speed and the second rotation speed, the method for adjusting the position of at least part of the baffle structure 50 of the air conditioning device to adjust the volume of the first area 1 and the second area 2 of the air conditioning device includes: when the first rotation speed is greater than the second rotation speed, the free portion 52 of the baffle structure 50 is controlled to rotate along the first rotation direction around the predetermined rotation axis. Alternatively, the free portion 52 of the baffle structure 50 is controlled to move toward the second fan 40. When the first rotation speed is less than the second rotation speed, the free portion 52 of the baffle structure 50 is controlled to rotate along the second rotation direction around the predetermined rotation axis. Alternatively, the free portion 52 of the baffle structure 50 is controlled to move toward the first fan 30. When the first rotation speed is equal to the second rotation speed, the baffle structure 50 is controlled to be in the starting position. In this way, when the first rotational speed is greater than the second rotational speed, the wind field of the corresponding part of the evaporator 20 and the first fan 30 is larger, and the wind field of the corresponding part of the evaporator 20 and the second fan 40 is smaller, and the free portion 52 moves along the first rotation direction or toward the second fan 40, thereby increasing the volume of the first area 1 and reducing the volume of the second area 2, so that the volume of the first area 1 is larger than the volume of the second area 2, thereby ensuring the uniformity of the wind field of the evaporator 20, improving the heat exchange efficiency of the evaporator 20, and avoiding damage to the evaporator 20 due to untimely heat exchange in the part with a larger wind field, thereby extending the service life of the evaporator 20. At the same time, when the first speed is less than the second speed, the wind field of the corresponding part of the evaporator 20 and the first fan 30 is smaller, and the wind field of the corresponding part of the evaporator 20 and the second fan 40 is larger, and the free portion 52 moves along the second rotation direction or toward the first fan 30, increasing the volume of the second area 2 and reducing the volume of the first area 1, so that the volume of the second area 2 is larger than the volume of the first area 1, thereby ensuring the uniformity of the wind field of the evaporator 20 and improving the heat exchange efficiency of the evaporator 20. When the first speed is equal to the second speed, the wind field of the first area 1 and the second area 2 is relatively uniform, and there is no need for the free portion 52 to adjust its position. While ensuring the uniformity of the wind field of the evaporator 20, it also reduces energy loss and ensures the energy saving of the air conditioning device.

[0080] In this embodiment, the first rotation direction is a direction toward the second fan 40 , and the second rotation direction is a direction toward the first fan 30 .

[0081] Specifically, the formula for determining the angle at which the free portion 52 of the baffle structure 50 rotates around the predetermined rotation axis is:

[0082]

[0083] Wherein, N1 is the first speed, N2 is the second speed, A is the angle of rotation of the free portion 52 along the predetermined rotation axis, and max is the maximum value of the first speed and the second speed. In this way, the above-mentioned setting provides a basis for calculating the angle of rotation of the free portion 52 of the baffle structure 50 around the predetermined rotation axis, determines the angle of rotation of the free portion 52 around the predetermined rotation axis under the relationship between the first speed and the second speed, and enables the free portion 52 to be accurately adjusted according to the changes of the first speed and the second speed, thereby ensuring the uniformity of the wind field and the accuracy of the rotation angle of the free portion 52.

[0084] Specifically, when A=0°, it means that the first rotational speed N1 and the second rotational speed N2 are equal, and the free part 52 does not need to rotate; when A>0°, it means that the first rotational speed N1 is greater than the second rotational speed N2, and the free part 52 rotates around the predetermined rotation axis along the first rotation direction to increase the volume of the first area 1; when A<0°, it means that the second rotational speed N2 is greater than the first rotational speed N1, and the free part 52 rotates around the predetermined rotation axis along the second rotation direction to increase the volume of the second area 2.

[0085] Specifically, the value of A satisfies: -45°≤A≤45°. In this way, the above setting limits the range of the angle of rotation of the free portion 52 around the predetermined rotation axis, and avoids the interference between the free portion 52 and the first fan 30 or the second fan 40 due to excessive rotation angle of the free portion 52, thereby reducing the operating reliability of the first fan 30 or the second fan 40, thereby ensuring the operating reliability between the first fan 30, the second fan 40 and the baffle structure 50. At the same time, the above setting also avoids the failure of the free portion 52 to be reset due to excessive rotation angle, thereby causing damage to the baffle structure 50, thereby extending the service life of the baffle structure 50.

[0086] like Figure 2 and Figure 6As shown, the air conditioning device further includes a first air guide component 60 and a second air guide component 70. The first air guide component 60 can be movably arranged at the first air outlet 11 to adjust the area where the first air outlet 11 blows out the gas. The second air guide component 70 can be movably arranged at the second air outlet 12 to adjust the area where the second air outlet 12 blows out the gas. The first air guide component 60 includes two first air guide plates 61 arranged opposite to each other, and the second air guide component 70 includes two second air guide plates 71 arranged opposite to each other. Among them, the two first air guide plates 61 are arranged in a one-to-one correspondence with the first air supply area 3 corresponding to the first fan 30, and the two second air guide plates 71 are arranged in a one-to-one correspondence with the second air supply area 4 corresponding to the second fan 40. The air conditioning device control method further includes: if the air supply mode of the first air supply area 3 is the first mode, controlling at least one first air guide plate 61 to swing back and forth within a first preset angle range. If the air supply mode of the first air supply area 3 is the second mode, one of the first air guide plates 61 is controlled to rotate to the first preset position, and the other first air guide plate 61 is controlled to rotate to the second preset position. If the air supply mode of the second air supply area 4 is the first mode, at least one second air guide plate 71 is controlled to swing back and forth within the second preset angle range. If the air supply mode of the second air supply area 4 is the second mode, one of the second air guide plates 71 is controlled to rotate to the third preset position, and the other second air guide plate 71 is controlled to rotate to the fourth preset position. In this way, the first air guide plate 61 and the second air guide plate 71 adjust the rotation state accordingly according to the air supply mode, so that the air supply mode of the first air outlet 11 and the second air outlet 12 meets the use requirements of different users, thereby improving the user's comfort.

[0087] like Figure 6 As shown, the first air guide plate 61 is arranged in a curved shape, and in the closed state, at least part of the inner wall surface of the two first air guide plates 61 is flush with at least part of the inner wall surface of the housing 10. The second air guide plate 71 is arranged in a curved shape, and in the closed state, at least part of the inner wall surface of the two second air guide plates 71 is flush with at least part of the inner wall surface of the housing 10. In this way, the above arrangement realizes the blowing of the gas at the first air outlet 11 by the first air guide assembly 60 and the blowing of the gas at the second air outlet 12 by the second air guide assembly 70 through the first air guide plate 61 and the second air guide plate 71, thereby ensuring the blowing reliability of the first air guide assembly 60 and the second air guide assembly 70. At the same time, the arrangement of the first air guide plate 61 and the second air guide plate 71, on the one hand, can better guide the airflow and reduce the turbulence of the airflow near the air guide plates, so that the airflow can be more smoothly delivered from the first air outlet 11 and the second air outlet 12, thereby improving the air supply smoothness and air supply efficiency of the air-conditioning device; on the other hand, it can prevent impurities from entering the interior of the air-conditioning device after the air-conditioning device is working, thereby ensuring the cleanliness of the air-conditioning device, reducing the maintenance cost of the air-conditioning device, and extending the service life of the air-conditioning device.

[0088] In this embodiment, the two first air guide plates 61 are arranged in parallel and at an interval, and the two first air guide plates 61 can rotate simultaneously.

[0089] In this embodiment, the two second air guide plates 71 are arranged in parallel and at intervals, and the two second air guide plates 71 can rotate simultaneously.

[0090] like Figure 6 As shown, when the air supply mode of the first air supply area 3 is the first mode, the first air guide plate 61 swings between angles a2 and a4 to supply air, so as to realize swinging and blowing the gas to the first air supply area 3; when the air supply mode of the first air supply area 3 is the second mode, the first air guide plate 61 rotates to an angle a1 to supply air, and then no longer swings, so as to avoid blowing the gas to the second air supply area 4. When the air supply mode of the second air supply area 4 is the first mode, the second air guide plate 71 swings between angles b1 and b3 to supply air, so as to realize swinging and blowing the gas to the second air supply area 4; when the air supply mode of the second air supply area 4 is the second mode, the second air guide plate 71 rotates to an angle b1 to supply air, and then no longer swings, so as to avoid blowing the gas to the second air supply area 4.
