[0032] The present invention provides a fresh air control method, and this fresh air control method is applicable to an air conditioner. Please refer to Figures 1 to 7 , along the preset horizontal direction, the air conditioner has a first side and a second side; the fresh air outlet of the air conditioner includes a first opening 11 and a second opening 12 distributed along the preset horizontal direction; the first opening 11 and the second opening 12 are respectively arranged corresponding to the first side and the second side of the air conditioner, so as to blow air to the first side and the second side of the air conditioner through the first opening 11 and the second opening 12 respectively.

[0033] Specifically, the first side and the second side of the air conditioner are the left side and the right side of the air conditioner respectively. In Figure 1 , Figure 3 , Figure 5 , the first side and the second side of the air conditioner are the left side and the right side of the air conditioner respectively.

[0034] In this application, the air conditioner includes a flow splitting portion 20 located between the first opening 11 and the second opening 12. The flow splitting portion 20 is movably arranged to change the opening sizes of the first opening 11 and the second opening 12, and further change the ventilation areas of the first opening 11 and the second opening 12, so as to change the air supply amounts on the first side and the second side of the air conditioner.

[0035] Specifically, the opening size of the first opening 11 is A1, and the opening size of the second opening 12 is A2.

[0036] Specifically, the flow splitting portion 20 is movably arranged so that the flow splitting portion 20 has a first state, a second state and a third state. That is, the flow splitting portion 20 has three states to respectively correspond to three air outlet states of the first opening 11 and the second opening 12.

[0037] When the flow splitting portion 20 is in the first state, the first opening 11 is larger than the second opening 12, that is, A1 is greater than A2, and the difference A1 - A2 is greater than or equal to C1. C1 must be greater than 0.

[0039] When the flow splitting portion 20 is in the second state, the first opening 11 is equal to the second opening 12, that is, A1 is equal to A2. Or, when the flow splitting portion 20 is in the second state, the first opening 11 is larger than the second opening 12, that is, A1 is greater than A2, and the difference A1 - A2 is less than C1. At this time, the difference A1 - A2 must be greater than 0. Or, when the flow splitting portion 20 is in the second state, the second opening 12 is larger than the first opening 11, that is, A2 is greater than A1, and the difference A2 - A1 is less than C2. At this time, the difference A2 - A1 must be greater than 0.

[0040] Optionally, C1 and C2 are equal or not equal.

[0041] It should be noted that when the first opening 11 is larger than the second opening 12, the air outlet of the first opening 11 is smoother than that of the second opening 12, the air outlet resistance of the first opening 11 is less than that of the second opening 12, and most of the fresh air is directed to the first opening 11 to meet the demand for a large amount of fresh air on the first side of the air conditioner. When the second opening 12 is larger than the first opening 11, the air outlet of the second opening 12 is smoother than that of the first opening 11, the air outlet resistance of the first opening 11 is greater than that of the second opening 12, and most of the fresh air is directed to the second opening 12 to meet the demand for a large amount of fresh air on the second side of the air conditioner.

[0042] In this application, the air supply gears of the fresh air fan include a first air supply gear, a second air supply gear, and a third air supply gear. The rotation speed of the fresh air fan in the third air supply gear is greater than that of the fresh air fan in the second air supply gear, and the rotation speed of the fresh air fan in the second air supply gear is greater than that of the fresh air fan in the first air supply gear.

[0043] Optionally, the first air supply gear is a low wind gear, the second air supply gear is a medium wind gear, and the third air supply gear is a high wind gear.

[0044] In this application, the fresh air control method includes: obtaining the number information P1 of the people in the preset area on the first side of the air conditioner and the number information P2 of the people in the preset area on the second side of the air conditioner; controlling the air supply gear of the fresh air fan of the air conditioner according to the sum of P1 and P2; and controlling the active state of the shunt part 20 according to the difference between P1 and P2 to control the ventilation areas of the first opening 11 and the second opening 12.

[0045] Using the fresh air control method of this application, the air supply gear of the fresh air fan can be adjusted according to the fresh air demand on the indoor side to adjust the fresh air delivery volume to the indoor side; and according to the fresh air demands on the first side and the second side of the air conditioner, the air outlet areas of the first opening 11 and the second opening 12 can be adjusted to adjust the fresh air delivery volumes on the first side and the second side of the air conditioner. It can be seen that using the fresh air control method of this application, the fresh air can be reasonably delivered according to the fresh air demand on the indoor side, thereby avoiding or reducing the phenomenon of excessive or insufficient fresh air indoors.

[0046] The fresh air control method of this application changes the state of the shunt part 20 to change the air outlet areas of the first opening 11 and the second opening 12, so as to change the air outlet volumes of the first opening 11 and the second opening 12, thereby reasonably distributing the fresh air delivery volume.

[0047] Specifically, when P1 + P2 < K1, control the fresh air fan to execute the first air supply gear; K1 > 0. When K1 ≤ P1 + P2 ≤ K2, control the fresh air fan to execute the second air supply gear; K1 < K2. When P1 + P2 > K2, control the fresh air fan to execute the third air supply gear.

[0053] When K1 ≤ P1 + P2 ≤ K2 and when P1 - P2 > K3 > 0, control the shunt part 20 to be in the first state.

[0054] When K1 ≤ P1 + P2 ≤ K2 and when K4 ≤ P1 - P2 ≤ K3, control the shunt part 20 to be in the second state; where K4 < 0.

[0055] When K1 ≤ P1 + P2 ≤ K2 and when P1 - P2 < K4, control the shunt part 20 to be in the third state.

[0057] Optionally, K4 is equal to -K3.

[0059] Optionally, K3 is 2 and K4 is -2.

[0060] The present invention also provides an air conditioner, as Figures 1 to 6 shown, which is applicable to the above fresh air control method.

[0061] Specifically, the air conditioner is a fresh air air conditioner.

[0062] Optionally, the air conditioner is an air conditioner cabinet.

[0063] Specifically, the indoor side of the air conditioner includes a heat exchanger system, an air duct system, a fresh air system, and a main control system, and the main control system is used to judge P1 + P2 and P1 - P2.

[0064] Optionally, the fresh air unit system is a unidirectional fresh air system.

[0065] Specifically, the fresh air system includes a fresh air fan, a fresh air inlet, a fresh air outlet, and fresh air ducts. Further, the fresh air system further includes a motor for driving the fresh air fan.

[0066] Optionally, the shunt part 20 can be arranged in the fresh air duct or the fresh air chamber in front of the fresh air outlet.

[0067] In the present application, the shunt part 20 of the air conditioner is rotatably arranged around a preset axis so that the shunt part 20 rotates among a first state, a second state, and a third state.

[0068] Specifically, the preset axis is parallel to the horizontal direction.

[0069] Specifically, the air conditioner includes a driving member; the driving member is connected to the shunt part 20 to drive the shunt part 20 to rotate around the preset axis. Optionally, the driving member is a motor. For example, the driving member is a stepping motor.

[0070] In the present application, as Figures 1 to 6 shown, the shunt part 20 has a cross-section 21 perpendicular to the preset axis, and the cross-section 21 is parallel to or coincides with the plane where the fresh air outlet of the air conditioner is located; the cross-section 21 includes a first side 211, a second side 212, and a third side 213 that are sequentially connected and joined end to end. The first side 211 and the second side 212 are both recessed toward the center of the cross-section 21, and the third side 213 protrudes away from the center of the cross-section 21.

[0071] When the shunt part 20 is in the second state, the first side 211 encloses a first opening 11 of the fresh air outlet, and the second side 212 encloses a second opening 12 of the fresh air outlet.

[0072] When the shunt part 20 is in the first state, the third side 213 encloses the second opening 12, and the second side 212 encloses the first opening 11, so that the first opening 11 is larger than the second opening 12.

[0073] When the shunt part 20 is in the third state, the third side 213 encloses the first opening 11, and the first side 211 encloses the second opening 12, so that the second opening 12 is larger than the first opening 11.

[0074] In this application, the connection point of the first side 211 and the second side 212 is the first connection point 214, the connection point of the second side 212 and the third side 213 is the second connection point 215, and the connection point of the third side 213 and the first side 211 is the third connection point 216. The first connection point 214, the second connection point 215, and the third connection point 216 are all located on a preset circle, and the angle between the first connection point 214 and the third connection point 216 is equal to the angle between the first connection point 214 and the second connection point 215, so that the arc length of the preset circle corresponding to the first side 211 is equal to the arc length of the preset circle corresponding to the second side 212.

[0075] Optionally, the angle between the second connection point 215 and the third connection point 216 is equal to the angle between the first connection point 214 and the third connection point 216, so that the arc length of the preset circle corresponding to the third side 213 is equal to the arc length of the preset circle corresponding to the first side 211.

[0076] Optionally, the angle between the second connection point 215 and the third connection point 216 is equal to the angle between the first connection point 214 and the second connection point 215, so that the arc length of the preset circle corresponding to the third side 213 is equal to the arc length of the preset circle corresponding to the second side 212.

[0077] Optionally, the first side 211 is arc-shaped, the second side 212 is arc-shaped, and the third side 213 is arc-shaped.

[0078] Optionally, when both the first side 211 and the second side 212 are arc-shaped, the radius of the circle where the first side 211 is located is equal to the radius of the circle where the second side 212 is located.

[0079] Optionally, when both the first side 211 and the third side 213 are arc-shaped, the radius of the circle where the first side 211 is located is equal to the radius of the circle where the third side 213 is located.

[0080] Optionally, when both the second side 212 and the third side 213 are arc-shaped, the radius of the circle where the second side 212 is located is equal to the radius of the circle where the third side 213 is located.

[0081] In this application, optionally, the flow splitting part 20 is a flow splitting cone.

[0082] In this application, the air conditioner includes a detection component to detect the number of people in the preset area on the first side of the air conditioner and the number of people in the preset area on the second side of the air conditioner.

[0083] Optionally, the detection component is a radar device; for example, the detection component is a millimeter-wave radar device.

[0084] Specifically, the detection component is arranged on the front side of the air conditioner, that is, the detection component is arranged on the front of the air conditioner.

[0085] Specifically, the air conditioner includes a display component, and the display component includes a display panel. Optionally, the display component includes a detection component.

[0086] Specifically, the detection component is communicatively connected to the main control system so that the main control system can judge P1 + P2 and P1 - P2 according to the detection result of the detection component.

[0087] In the specific implementation process, if P1 + P2 < K1, at this time the main control system judges that the required fresh air volume in the room is not high, and the difference in fresh air demand between the first side and the second side (i.e., the left and right sides) of the air conditioner is small, so that the shunt part 20 is in the second state, and the fresh air fan operates at a low gear. When the shunt part 20 is in the second state, the air outlet resistance of the first opening part 11 and the second opening part 12 can be reduced; making the fresh air fan operate at the lowest speed can reduce the power consumption of the fresh air fan, and reasonably reduce the heat load brought by the fresh air to the room.

[0088] If K1 ≤ P1 + P2 ≤ K2, at this time the main control system judges that there are many people in the room, the fresh air volume demand is high, and the fresh air demand in the first side area and the second side area of the air conditioner will be different according to the number of people. Therefore, a further judgment is made on the basis of K1 ≤ P1 + P2 ≤ K2.

[0089] If K1 ≤ P1 + P2 ≤ K2 and P1 - P2 > K3 > 0, the main control system judges that the fresh air demand on the first side of the air conditioner is high and the fresh air demand on the second side is low, so that the shunt part 20 is in the first state, and the fresh air fan operates at a medium gear; at this time, the fresh air demand on the first side can be reasonably met, and the heat load brought by the excess fresh air on the second side is reduced.

[0090] If K1 ≤ P1 + P2 ≤ K2 and K4 ≤ P1 - P2 ≤ K3, the main control system judges that the difference in fresh air demand between the first side and the second side of the air conditioner is small, so that the shunt part 20 is in the second state, and the fresh air fan operates at a medium gear; at this time, the fresh air demands on both the first side and the second side can be met.

[0091] If K1 ≤ P1 + P2 ≤ K2 and P1 - P2 < K4, the main control system judges that the fresh air demand on the second side of the air conditioner is high and the fresh air demand on the first side is low, so that the shunt part 20 is in the third state, and the fresh air fan operates at a medium gear; at this time, the fresh air demand on the second side can be reasonably met, and the heat load brought by the excess fresh air on the first side is reduced.

[0092] If P1 + P2 > K2, the main control system determines that there are many people indoors and the fresh air demand is large. In this case, it no longer judges the difference in the number of people on the first side and the second side of the air conditioner, and adjusts the load with the maximum fresh air delivery volume, so that the shunt part 20 is in the second state, and the fresh air fan operates at a high wind speed to maximize the fresh air demand indoors, thereby forming a healthy and comfortable air state on the indoor side. Among them, the rotation speed of the fresh air fan when it is at a high wind speed refers to the rotation speed of the fresh air fan when it is at a medium wind speed plus the correction value A, which is equivalent to increasing the maximum threshold value of the fresh air volume of the fresh air fan.

[0093] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0094] In the fresh air control method provided by the present invention, it includes: obtaining the number information P1 of the preset area on the first side of the air conditioner and the number information P2 of the preset area on the second side of the air conditioner; controlling the air supply gear of the fresh air fan of the air conditioner according to the sum of P1 and P2; and controlling the activity state of the shunt part 20 according to the difference between P1 and P2 to control the ventilation areas of the first opening 11 and the second opening 12.

[0095] Using the fresh air control method of the present application, the air supply gear of the fresh air fan can be adjusted according to the fresh air demand on the indoor side to adjust the fresh air delivery volume to the indoor side; and according to the fresh air demands on the first side and the second side of the air conditioner, the air outlet areas of the first opening 11 and the second opening 12 are adjusted to adjust the fresh air delivery volumes on the first side and the second side of the air conditioner. It can be seen that using the fresh air control method of the present application, the fresh air can be reasonably delivered according to the fresh air demand on the indoor side, thereby avoiding or reducing the phenomenon of excessive or insufficient fresh air indoors, and further avoiding or reducing the problem of increased indoor side heat load caused by excessive fresh air indoors.

[0096] The fresh air control method of the present application changes the state of the shunt part 20 to change the air outlet areas of the first opening 11 and the second opening 12, so as to change the air outlet volumes of the first opening 11 and the second opening 12, thereby changing the fresh air delivery volumes on the first side and the second side of the air conditioner to conduct fresh air delivery direction adjustment, avoiding or reducing the problem of excessive or insufficient fresh air in the first side area and the second side area of the air conditioner, and thus avoiding or reducing the problem of increased heat load in the first side area and the second side area caused by excessive fresh air in the first side area and the second side area of the air conditioner.

[0097] The fresh air control method of the present application determines the regional fresh air demand according to the number of people and the difference in the number of people on the first side and the second side of the air conditioner; and reasonably distributes the fresh air delivery volume by changing the state of the shunt part 20.

[0098] The fresh air control method of the present application maximally ensures the rationality of fresh air delivery, can reduce the fresh air volume in areas with small fresh air demand, thereby reducing the heat load brought by fresh air to the room and achieving an energy-saving effect.

It should be understood that the data used in this way can be interchanged under appropriate circumstances so that the embodiments of the present application described here can be implemented in an order other than those illustrated or described here. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device including a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0100] For the sake of convenience of description, spatial relative terms such as "above...", "over...", "on the upper surface of...", "above" etc. can be used here to describe the spatial position relationship between a device or feature shown in the figure and other devices or features. It should be understood that the spatial relative terms are intended to include different orientations in use or operation other than the orientation described in the figure for the device. For example, if the device in the figure is inverted, the device described as "above other devices or structures" or "over other devices or structures" will then be positioned as "below other devices or structures" or "under other devices or structures". Thus, the exemplary term "above..." can include both the orientations of "above..." and "below...". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding interpretations should be made for the spatial relative descriptions used here.

[0101] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
