DETAILED DESCRIPTION

[0037] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0038] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplicity and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present invention provides various specific processes and examples of materials, but those of ordinary skill in the art can be aware of the applicability of other processes and / or the use of other materials.

[0039] It should be noted that, unless otherwise specified, the X direction in this application is the front-to-back direction of the body 1 of the air conditioner 100 , the Y direction is the left-right direction of the body 1 of the air conditioner 100 , and the Z direction is the height direction of the body 1 of the air conditioner 100 .

[0040] Reference below Figure 1-Figure 10 An air conditioner 100 according to an embodiment of the present invention is described.

[0041] An air conditioner 100 according to an embodiment of the present invention includes a body 1 .

[0042] Specifically, Figure 1 and Figure 2 As shown, the body 1 is provided with a first air outlet 11 and a second air outlet 12, the first air outlet 11 is located on the front side of the body 1, and the second air outlet 12 is located on the left side and / or right side of the body 1; wherein, a first air duct 21 and a second air duct 22 are provided in the body 1, the first air duct 21 is connected with the first air outlet 11, and the second air duct 22 is connected with the second air outlet 12, the first air duct 21 and the second air duct 22 are distributed in the height direction of the body 1, and the first air outlet 11 and the second air outlet 12 are distributed in the height direction of the body 1.

[0043] Therefore, the first air outlet 11 and the second air outlet 12 can discharge air in different directions at different heights of the body 1, so that the air conditioner 100 can achieve full-area air supply, thereby reducing air supply blind spots, and can reduce problems such as large heating temperature stratification, greatly improving comfort.

[0044] For example, the air conditioner 100 may be a cabinet-type air conditioner or a wall-mounted air conditioner, etc., which is not limited here.

[0045] The air conditioner 100 is taken as a cabinet air conditioner as an example for description below. The air conditioner 100 includes: a body 1.

[0046] The body 1 is provided with an air inlet area 13 and an air outlet, and a first air duct 21, a second air duct 22, an air duct partition 14, an evaporator 16 and an electric heating component 15 are provided in the body 1, and the body 1 is provided with an air outlet open to the outside, the air outlet includes a first air outlet 11 and a second air outlet 12, the first air outlet 11 is located on the front side of the body 1, and the second air outlet 12 is located on the left side and / or right side of the body 1.

[0047] For example Figure 1-Figure 5 As shown, two second air outlets 12 are provided, and the two second air outlets 12 are respectively located on the left and right sides of the body 1 to form a left air outlet and a right air outlet. The second air outlet 12 may be located on the side of the body 1, or the second air outlet 12 may be located at the connection between the front and the side of the body 1, that is, the opening direction of the second air outlet 12 intersects with the left and right direction of the body 1 and is not perpendicular, while the opening direction of the first air outlet 11 is perpendicular to the left and right direction of the body 1.

[0048] In this way, by setting the positions of the first air outlet 11 and the second air outlet 12 to be different, so that the opening directions of the first air outlet 11 and the second air outlet 12 are different, the first air outlet 11 and the second air outlet 12 can discharge air in different directions to expand the air outlet angle of the air conditioner 100, and multiple air outlets can discharge air at the same time, which can improve the air outlet efficiency of the air conditioner 100.

[0049] There are two second air ducts 22, which correspond to the two second air outlets 12, respectively, and an air duct partition 14 is provided between the inlet ends of the two second air ducts 22, so that the air inlet area 13 is separated into two sub-areas by the air duct partition 14, and the two sub-areas are respectively used to realize the air inlet of the two second air ducts 22. In this way, the air conditioner 100 can realize single-side air outlet by using a single second air duct 22 and its corresponding second air outlet 12, thereby meeting different usage requirements of the air conditioner 100.

[0050] For example Figure 6-Figure 8 As shown, an air inlet area 13 is provided on the rear side of the body 1, and the evaporator 16 is opposite to the air inlet area 13 and is located between the air inlet end of the first air duct 21 and the air inlet end of the second air duct 22 and the air inlet area 13. The evaporator 16 is used to cool the air entering the first air duct 21 or the second air duct 22 so that the air conditioner 100 can blow out cold air for cooling.

[0051] In this way, the first air duct 21 and the second air duct 22 can share the evaporator 16, so there is no need to separately provide the evaporator 16, so as to simplify the structure of the air conditioner 100 and reduce the production cost.

[0052] like Figure 6-Figure 8As shown, two electric heating components 15 are provided, and both electric heating components 15 are located between the air inlet end of the first air duct 21 and the evaporator 16, and the two electric heating components 15 are respectively located between the air inlet ends of the two second air ducts 22 and the evaporator 16, and the electric heating components 15 are used to heat the air entering the first air duct 21 or the second air duct 22, so that the air outlet of the air conditioner 100 can blow out hot air, thereby realizing the heating function of the air conditioner 100.

[0053] In this way, two electric heating components 15 can be used to simultaneously heat the airflow entering the air inlet end of the first air duct 21 to improve the heating efficiency, and the two electric heating components 15 can respectively heat the airflow entering the air inlet ends of the two second air ducts 22, so that a single electric heating component 15 can be used to heat the airflow in the second air duct 22 corresponding to it, thereby meeting the different usage requirements of the air conditioner 100.

[0054] Furthermore, if Figure 1-Figure 5 As shown, the first air outlet 11 and the second air outlet 12 are distributed in the height direction of the body 1, so that the first air outlet 11 and the second air outlet 12 can discharge air at different heights, thereby reducing the problem of large heating temperature stratification and improving the use comfort of the air conditioner 100.

[0055] The first air duct 21 and the second air duct 22 are also distributed in the height direction of the body 1, so that the first air duct 21 and the second air duct 22 can be more easily adapted to the first air outlet 11 and the second air outlet 12. In this way, the cross section of the air conditioner 100 at the height of the first air outlet 11 (such as Figure 6 or Figure 7 ) and the cross section at the height of the second air outlet 12 (as shown in Figure 8 As shown in the figure, the air supply form of the air conditioner 100 is enriched, which is beneficial to improving the comfort of the air conditioner 100.

[0056] According to the air conditioner 100 of the embodiment of the present invention, the first air outlet 11 and the second air outlet 12 are located in different directions of the body 1 and are distributed in the height direction of the body 1, so that the first air outlet 11 and the second air outlet 12 can discharge air in different directions at different heights of the body 1, so that the air conditioner 100 can achieve full-area air supply, thereby reducing air supply blind spots, and can reduce problems such as large heating temperature stratification, thereby greatly improving comfort.

[0057] In some embodiments, Figure 2 As shown, the air conditioner 100 further includes: a crossflow fan wheel 3 and a driving member 4, a part of the crossflow fan wheel 3 is located in the first air duct 21 and the other part is located in the second air duct 22, and the driving member 4 is connected to the crossflow fan wheel 3 to drive the crossflow fan wheel 3 to rotate.

[0058] Specifically, the driving member 4 drives the crossflow impeller 3 to rotate to drive the airflow entering the air intake area into the first air duct 21 and / or the second air duct 22, so that the flow rate of the airflow can be increased, thereby improving the heating or cooling efficiency of the air conditioner 100.

[0059] Specifically, a portion of the crossflow wind wheel 3 is located in the first air duct 21 and the other portion is located in the second air duct 22, so that the first air duct 21 and the second air duct 22 can share the crossflow wind wheel 3, thereby reducing the difficulty of setting the crossflow wind wheel 3, wherein the "crossflow wind wheel 3" in the above description does not completely refer to one crossflow wind wheel 3.

[0060] For example, when there are two second air outlets 12 and two second air ducts 22, there are also two crossflow wind wheels 3, and the two crossflow wind wheels 3 correspond one-to-one to the air inlet ends of the two second air ducts 22. At the same time, at least parts of the two crossflow wind wheels 3 are located at the inlet end of the first air duct 21.

[0061] It should be noted that, in the air conditioner 100, the axial direction of the cross-flow fan wheel 3 usually extends along the height direction of the air conditioner 100. Therefore, when the first air duct 21 and the second air duct 22 can share the cross-flow fan wheel 3 and the first air duct 21 and the second air duct 22 are distributed in the height direction of the body 1, the air inlet end of the first air duct 21 and the air inlet end of the second air duct 22 are spaced apart and distributed in the axial direction of the cross-flow fan wheel 3 and are both open in the direction of the cross-flow fan wheel 3.

[0062] In this way, the first air duct 21 and the second air duct 22 can share the crossflow wind wheel 3, thereby reducing the difficulty of installing the crossflow wind wheel 3.

[0063] In some embodiments, Figure 2 As shown, the first air duct 21 is located above the second air duct 22 , the first air outlet 11 is located above the second air outlet 12 , and the driving member 4 is located on a side of the second air duct 22 away from the first air duct 21 .

[0064] As a result, the position of the driving member 4 in the height direction of the body 1 is lower, so that the driving member 4 will not occupy the layout space above the first air duct 21. In this way, the highest position of the first air outlet 11 in the height direction of the body 1 can be arranged higher, thereby enhancing the air supply effect.

[0065] In some embodiments, Figure 3 As shown, the first air duct 21 is located above the second air duct 22 , the first air outlet 11 is located above the second air outlet 12 , and the driving member 4 is located on a side of the first air duct 21 away from the second air duct 22 .

[0066] As a result, the driving member 4 is positioned higher in the height direction of the machine body 1, so that the driving member 4 does not occupy the arrangement space below the second air duct 22, and the driving member 4 is positioned higher, which is convenient for subsequent loading, unloading or maintenance.

[0067] In some embodiments, Figure 4 As shown, the first air duct 21 is located below the second air duct 22 , the first air outlet 11 is located below the second air outlet 12 , and the driving member 4 is located on a side of the second air duct 22 away from the first air duct 21 .

[0068] As a result, the driving member 4 is positioned higher in the height direction of the machine body 1, so that the driving member 4 does not occupy the arrangement space below the first air duct 21, and the driving member 4 is positioned higher, which is convenient for subsequent loading, unloading or maintenance.

[0069] In some embodiments, Figure 5 As shown, the first air duct 21 is located below the second air duct 22 , the first air outlet 11 is located below the second air outlet 12 , and the driving member 4 is located on a side of the first air duct 21 away from the second air duct 22 .

[0070] As a result, the position of the driving member 4 in the height direction of the body 1 is lower, so that the driving member 4 will not occupy the layout space above the second air duct 22. In this way, the highest position of the second air outlet 12 in the height direction of the body 1 can be arranged higher, thereby enhancing the air supply effect.

[0071] In some embodiments, the air conditioner 100 further includes an air guide 5 , and the first air outlet 11 and / or the second air outlet 12 is provided with the air guide 5 .

[0072] Therefore, when air is discharged from the first air outlet 11 and / or the second air outlet 12 , the air flow can be guided, thereby improving the air discharge effect of the first air outlet 11 and / or the second air outlet 12 .

[0073] In some embodiments, the guide member 5 is configured as a guide cone, and the guide cone is located at the first air outlet 11. In this way, the airflow can be guided when the first air outlet 11 discharges air, thereby improving the air discharge effect of the first air outlet 11.

[0074] Furthermore, in the air outlet direction of the first air outlet 11, the cross-sectional area of ​​the guide cone gradually decreases, which is beneficial to improving the guide effect of the guide cone.

[0075] In some other embodiments, the guide member 5 may also be configured as a guide plate or other guide structures.

[0076] In some embodiments, the air conditioner 100 further includes a swing blade 6, which is rotatably mounted on the first air outlet 11, and the swing blade 6 is suitable for swinging between 45° upward in the horizontal direction and 45° downward in the horizontal direction.

[0077] Therefore, the air outlet direction of the first air outlet 11 can be adjusted by rotating the swing blade 6, thereby increasing the air supply angle of the first air outlet 11, and facilitating increasing the air supply range of the air conditioner 100, thereby improving its comfort.

[0078] The invention also provides a control method for the air conditioner.

[0079] According to the control method for an air conditioner according to an embodiment of the present invention, the control method is applicable to the air conditioner 100 of any of the above embodiments, and the control method includes:

[0080] S10: Acquire the current operation mode of the air conditioner 100;

[0081] S20: Obtaining a first difference between the set temperature of the air conditioner 100 and the first return air temperature;

[0082] S30: According to the relationship between the first difference and the first threshold, the air outlet states of the first air outlet 11 and the second air outlet 12 of the air conditioner 100 are controlled.

[0083] For example, the air inlet area 13 of the air conditioner 100 may be provided with a detection device for detecting the first return air temperature. It should be noted that the "first difference" refers to the difference between the larger value of the set temperature and the first return air temperature minus the smaller value.

[0084] Thus, the difference between the first return air temperature and the set temperature in different operating modes of the air conditioner 100 can be compared with the first threshold value, so as to automatically adjust the air outlet states of the first air outlet 11 and the second air outlet 12. In this way, the air outlet mode of the air conditioner 100 can be automatically switched, which is beneficial to improving the automation degree of the air conditioner 100, and further improving the comfort of use of the air conditioner 100.

[0085] Among them, the first air outlet 11 and the second air outlet 12 are located in different directions of the body 1 and are distributed in the height direction of the body 1. In this way, the first air outlet 11 and the second air outlet 12 can discharge air in different directions at different heights of the body 1, so that the air conditioner 100 can achieve multiple modes of air supply, greatly improving comfort.

[0086] In some embodiments, the current operating mode includes: global heating mode and global cooling mode, and when the current operating mode is global heating mode or global cooling mode, the swing blade 6 of the first air outlet 11 is controlled to swing between a horizontal upward rotation of 45° and a horizontal downward rotation of 45°, and the second air outlet 12 is controlled to discharge air at a maximum air volume.

[0087] Therefore, in the global heating mode and the global cooling mode, the second air outlet 12 discharges air at the maximum air volume, and the first air outlet 11 can swing to discharge air at an angle between 45° horizontally upward and 45° horizontally downward, which can improve the air outlet efficiency and angle of the air conditioner 100.

[0088] At the same time, the first air outlet 11 and the second air outlet 12 are located in different directions of the body 1 and are distributed in the height direction of the body 1. In this way, the first air outlet 11 and the second air outlet 12 can discharge air in different directions at different heights of the body 1, so that the air conditioner 100 can achieve full-area air supply, thereby reducing air supply blind spots, and can reduce problems such as large heating temperature stratification, greatly improving comfort.

[0089] In some embodiments, when the current operating mode is the global heating mode, if the first difference is less than the first threshold, the air conditioner 100 is controlled to switch to the carpet heating mode. In the carpet heating mode, the swing blade 6 is controlled to rotate horizontally downward by 45° and the second air outlet 12 is controlled to discharge air at a volume of 40%.

[0090] It should be noted that when the current operating mode is the global heating mode, the ambient temperature (equivalent to the first return air temperature in this embodiment) is generally lower than the set temperature, that is, when the current operating mode is the global heating mode, the "first difference" is the value obtained by subtracting the set temperature from the first return air temperature.

[0091] For example, the first threshold is 0.5°. When the set temperature minus the first return air temperature is less than 0.5°, the swing blade 6 is controlled to rotate 45° horizontally downward and the second air outlet 12 is controlled to discharge air at 40% of the air volume.

[0092] In this way, the air outlet angle of the first air outlet 11 is closer to the bottom of the body 1. When the body 1 is placed on the ground, the air outlet angle of the first air outlet 11 is closer to the ground, and the second air outlet 12 discharges air at 40% of the maximum air volume. In this way, an surround + carpet-style heating mode (the carpet-style heating mode in this embodiment) can be achieved.

[0093] Since the air outlet angle of the first air outlet 11 is closer to the ground, the temperature stratification phenomenon in the area corresponding to the first air outlet 11 and the second air outlet 12 can be reduced, thereby improving the uniformity of heating temperature.

[0094] It should be noted that since the set temperature - the first return air temperature is less than 0.5°, it means that the difference between the first return air temperature and the set temperature is small. At this time, it is necessary to reduce the heating amount of the air conditioner 100 to avoid overheating. Therefore, it is necessary to control the second air outlet 12 to discharge air at 40% air volume.

[0095] When the set temperature minus the first return air temperature is not less than 0.5°, it indicates that the difference between the set temperature and the first return air temperature is large. Therefore, the air conditioner 100 needs to be controlled to maintain the global heating mode to achieve rapid heating.

[0096] In some embodiments, when the current operating mode is the full-area cooling mode, if the first difference is less than the first threshold, the air conditioner 100 is controlled to switch to the shower-type cooling mode. In the shower-type cooling mode, the swing blade 6 is controlled to rotate horizontally upward by 45° and the second air outlet 12 is controlled to discharge air at a volume of 40%.

[0097] It should be noted that when the current operating mode is the global cooling mode, the ambient temperature (equivalent to the first return air temperature in this embodiment) is generally greater than the set temperature, that is, when the current operating mode is the global cooling mode, the "first difference" is the value obtained by subtracting the first return air temperature from the set temperature.

[0098] For example, the first threshold is 0.5°. When the first return air temperature minus the set temperature is less than 0.5°, the swing blade 6 is controlled to rotate 45° horizontally upward and the second air outlet 12 is controlled to discharge air at 40% of the air volume.

[0099] In this way, the air outlet angle of the first air outlet 11 is closer to the top of the body 1. When the body 1 is placed on the ground, the air outlet angle of the first air outlet 11 is farther away from the ground, and the second air outlet 12 discharges air at 40% of the maximum air volume. In this way, an embrace + shower-type cooling mode (the shower-type cooling mode in this embodiment) can be achieved.

[0100] Since the air outlet angle of the first air outlet 11 is farther away from the ground, the cold air rises first and then falls under the action of gravity after being blown out from the first air outlet 11, thereby forming a "shower" type cooling mode. In this way, the temperature stratification phenomenon in the area corresponding to the first air outlet 11 and the second air outlet 12 can be reduced, thereby improving the uniformity of the cooling temperature.

[0101] It should be noted that since the first return air temperature - the set temperature is less than 0.5°, it means that the difference between the first return air temperature and the set temperature is small. At this time, it is necessary to reduce the cooling capacity of the air conditioner 100 to avoid over-cooling. Therefore, it is necessary to control the second air outlet 12 to discharge air at 40% air volume.

[0102] When the first return air temperature minus the set temperature is not less than 0.5°, it indicates that the difference between the set temperature and the first return air temperature is large. Therefore, the air conditioner 100 needs to be controlled to maintain the full-range cooling mode to achieve rapid cooling.

[0103] In some embodiments, when the current operating mode is the shower-style cooling mode, the second difference between the set temperature of the air conditioner 100 and the second return air temperature is obtained. If the second difference is less than the second threshold, the first air outlet 11 is controlled to keep blowing air and the second air outlet 12 is closed to enter the windless mode.

[0104] It should be noted that when the current operating mode is the shower-type cooling mode, the ambient temperature (equivalent to the second return air temperature in this embodiment) is generally lower than the set temperature, that is, when the current operating mode is the shower-type cooling mode, the "first difference" is the value obtained by subtracting the set temperature from the second return air temperature.

[0105] For example, if the second threshold is 2°, when the set temperature minus the second return air temperature is less than 2°, the first air outlet 11 is controlled to keep the air out (the swing blade 6 is horizontally upward at 45°) and the second air outlet 12 is closed to enter the windless mode.

[0106] In this way, the air outlet angle of the first air outlet 11 is closer to the top of the body 1. When the body 1 is placed on the ground, the air outlet angle of the first air outlet 11 is farther away from the ground, and the second air outlet 12 is closed, so that a windless mode can be achieved.

[0107] Since the outlet angle of the first air outlet 11 is farther from the ground, the cold air first rises and then falls under the action of gravity after being blown out from the first air outlet 11, that is, when maintaining cooling to maintain the set temperature, direct blowing is avoided to achieve a windless mode.

[0108] It should be noted that since the set temperature - the second return air temperature is less than 2°, it means that the difference between the second return air temperature and the set temperature is small. At this time, it is necessary to reduce the cooling capacity of the air conditioner 100 to avoid over-cooling. Therefore, it is necessary to control the second air outlet 12 to be closed.

[0109] When the set temperature minus the second return air temperature is not less than 2°, it indicates that the difference between the set temperature and the second return air temperature is large. Therefore, the air conditioner 100 needs to be controlled to maintain the shower cooling mode to achieve rapid cooling.

[0110] In some embodiments, when the current operating mode is the windless mode, a third difference between the set temperature and the third return air temperature is obtained, and if the third difference is greater than a third threshold, a relationship between the third difference and the second threshold is determined;

[0111] If the third difference is greater than the second threshold, the air conditioner 100 is controlled to switch to the global cooling mode;

[0112] If the third difference is less than or equal to the second threshold, the air conditioner 100 is controlled to switch to the shower cooling mode.

[0113] It should be noted that when the current operating mode is the windless mode, due to the decrease in cooling capacity, the ambient temperature (equivalent to the third return air temperature in this embodiment) is generally greater than the set temperature over a long period of time. That is, when the current operating mode is the windless mode, the "first difference" is the value obtained by subtracting the third return air temperature from the set temperature.

[0114] For example, the first threshold is 1°, then when the third return air temperature - the set temperature is not greater than 2°, the windless mode is maintained, and when the third return air temperature - the set temperature is greater than 1°, the relationship between the third difference and the second threshold is determined.

[0115] If the third difference is greater than the second threshold, it means that the third return air temperature is greater than the set temperature, and the air conditioner 100 is controlled to switch to the global cooling mode for rapid cooling.

[0116] If the third difference is less than or equal to the second threshold, it means that the third return air temperature is smaller than the set temperature, and the air conditioner 100 is controlled to switch to the shower cooling mode to gradually achieve cooling in a gentler manner to avoid over-cooling.

[0117] The following is combined with Figure 1-Figure 10 A preferred embodiment of an air conditioner 100 of the present invention is described below:

[0118] The air conditioner 100 includes a body 1. The body 1 is provided with an air inlet area 13 and an air outlet, and the body 1 is provided with a first air duct 21, a second air duct 22, an air duct partition 14, an air duct bottom shell component 2, an evaporator 16 and an electric heating component 15, and the body 1 is provided with an air outlet open to the outside, the air outlet includes a first air outlet 11 and a second air outlet 12, and the first air outlet 11 is located at the front side of the body 1, that is, the middle air outlet.

[0119] There are two second air outlets 12, which are respectively located on the left and right sides of the machine body 1 to form a left air outlet and a right air outlet, wherein there are also two second air ducts 22, which correspond to the two second air outlets 12 one by one, and an air inlet area 13 is provided at the rear side of the machine body 1, and an evaporator 16 is directly opposite to the air inlet area 13 and is located between the air inlet end of the first air duct 21 and the air inlet end of the second air duct 22 and the air inlet area 13, and the evaporator 16 is used to cool the air entering the first air duct 21 or the second air duct 22 so that the air conditioner 100 can blow out cold air for cooling. There are two electric heating components 15, which are both located between the air inlet end of the first air duct 21 and the evaporator 16, and the two electric heating components 15 are respectively located between the air inlet ends of the two second air ducts 22 and the evaporator 16.

[0120] The first air outlet 11 and the second air outlet 12 are distributed in the height direction of the machine body 1 , and the first air duct 21 and the second air duct 22 are also distributed in the height direction of the machine body 1 .

[0121] The control method of the present invention is adopted when the air conditioner is actually used, and its specific control logic is as follows:

[0122] The air conditioner 100 is turned on, and then an operation mode is selected. The operation mode includes a heating mode and a cooling mode:

[0123] When the heating mode is selected, and the heating mode is the full-area heating mode: the left air outlet + the right air outlet + the middle air outlet operate simultaneously, the left and right air outlets discharge air at the maximum air volume, and the swing blade 6 of the middle air outlet enters the wind sweeping mode (angle horizontally downward 45° to horizontally upward 45°). Then, determine whether the T0-T1 difference is less than 0.5℃. If so, switch to the surround + carpet heating mode: the left + right + middle air outlets operate simultaneously, the left and right air outlets discharge air at 40% of the air volume, and the middle air outlet swing blade 6 descends horizontally 45°. Otherwise, continue to operate the full-area heating mode.

[0124] When the cooling mode is selected, and the cooling mode is the full-area cooling mode: the left air outlet + the right air outlet + the middle air outlet run at the same time, the left and right air outlets discharge air at the maximum air volume, and the middle air outlet swing blade 6 enters the sweeping mode (angle horizontally downward 45° to horizontally upward 45°), then, determine whether the T1-T0 difference is less than 0.5℃, if so, switch to the surround + shower cooling mode: the left air outlet + the right air outlet + the middle air outlet run at the same time, the left and right air outlets discharge air at 40% of the air volume, and the swing blade 6 of the middle air outlet is horizontally downward 45°, if not, continue to run the full-area cooling mode.

[0125] Then, determine whether the T0-T2 difference is less than 2°, if so, enter the windless mode: the left and right air outlets are in a windless state, and the middle air outlet swing blade 6 is horizontally upward at 45°, if otherwise, continue to run the surround + shower cooling mode, then determine whether the T3-T0 difference is greater than 1°C, if so, determine whether the T3-T0 difference is greater than 2°C, if otherwise, continue to run the windless mode.

[0126] When the T3-T0 difference is greater than 1°C, continue to determine whether the T3-T0 difference is greater than 2°C. If so, run the full-area cooling mode, otherwise run the surround + shower cooling mode.
