[0038] In order to be able to understand the features and technical contents of the embodiments of the present disclosure in more detail, the implementation of the embodiments of the present disclosure is described in detail below in conjunction with the accompanying drawings. The attached drawings are for reference only and are not used to limit the embodiments of the present disclosure.

For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present disclosure can be understood according to specific circumstances.

[0042] Unless otherwise stated, the term "plurality" means two or more.

[0043] In the embodiment of the present disclosure, the character " / " indicates that the preceding and following objects are in an "or" relationship. For example, A / B indicates: A or B.

[0044] The term "and / or" is a description of the association relationship between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or, A and B.

[0045] The term "correspondence" may refer to an association relationship or a binding relationship. The correspondence between A and B means that there is an association relationship or a binding relationship between A and B.

[0046] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0047] The air supply system of the air conditioner outdoor unit is driven by the power source output by the fan blower, which drives the fan to rotate at high speed. The wind circle and the fan are matched according to the optimized wind field design. When the fan rotates, it can output a large amount of air under the cooperation of the fan wind circle. The top of the fan is a positive pressure area, and the air inlet area at the bottom of the fan is a negative pressure area. In the overall structure of the air conditioner outdoor unit, during the high-speed rotation of the fan, the wind outside the heat exchanger is in a negative pressure area. Under the action of the pressure difference between the inside and outside of the heat exchanger, the effect of air flow and heat exchange is generated. For the top-outlet air conditioner outdoor unit, due to the large height size of the heat exchanger, the height difference between the top fan and the bottom area of ​​the heat exchanger is large, resulting in low wind speed and poor heat exchange efficiency in the heat exchanger at the bottom area of ​​the air conditioner outdoor unit; while the upper area of ​​the heat exchanger closer to the fan has a higher wind speed and better heat exchange efficiency, resulting in different heat exchange efficiencies in the upper and lower areas of the heat exchanger, and the heat exchange efficiency of the heat exchanger cannot be maximized, resulting in a large area of ​​heat exchangers used in the air conditioner outdoor unit, high cost, insufficient heat exchange efficiency, and affecting the performance of the whole machine. In addition, during the use of the air conditioner outdoor unit, there may be abnormal objects blocking the surface of the heat exchanger, causing the wind flowing through the heat exchanger to decrease, or even blocking the area so that no wind flows through, resulting in poor heat exchange and abnormal heat exchange problems.

[0048] like Figure 1 As shown, an embodiment of the present disclosure provides an air conditioner, including a heat exchanger 1 and a fan 2 located above the heat exchanger 1 , and also including: a first wind speed detection device 41 , a second wind speed detection device 42 and a wind speed adjustment device 3 .

[0049] The first wind speed detecting device 41 is arranged on the surface of the heat exchanger 1; the second wind speed detecting device 42 is arranged on the surface of the heat exchanger 1 and is located below the first wind speed detecting device 41; the wind speed adjusting device 3 is arranged at the wind guide end at the bottom of the wind circle of the fan 2, and can adjust the wind speed entering the wind circle of the fan 2 according to the wind speed detected by the first wind speed detecting device 41 and the second wind speed detecting device 42.

[0050] The heat exchange efficiency of the heat exchanger 1 is mainly reflected by the wind speed flowing through the heat exchanger 1. The greater the wind speed, the higher the heat exchange efficiency of the area in the heat exchanger 1; the smaller the wind speed, the lower the heat exchange efficiency of the area in the heat exchanger 1. The first wind speed detection device 41 and the second wind speed detection device 42 can measure the wind speed of the upper and lower areas of the heat exchanger 1, so as to determine the heat exchange efficiency of the upper and lower areas of the heat exchanger 1. When there is a large difference in the heat exchange efficiency between the upper and lower areas, the wind speed adjustment device 3 can timely adjust the wind speed of the upper area of ​​the heat exchanger 1 entering the wind circle of the fan 2 to reduce the difference between the wind speeds of the upper and lower areas of the heat exchanger 1.

[0051] Optionally, the wind speed detection device 4 includes a wind speed sensor.

[0052] Optionally, the first wind speed detecting device 41 is arranged in the middle part of the upper surface area of ​​the heat exchanger 1 ; the second wind speed detecting device 42 is arranged below the first wind speed detecting device and located in the middle part of the lower surface area of ​​the heat exchanger 1 .

[0053] Optionally, there may be multiple first wind speed detection devices 41 ; and there may be multiple second wind speed detection devices 42 .

[0054] The wind speed detection devices 4 are distributed in the middle part of the upper and lower regions of the heat exchanger 1, and can more accurately reflect the wind speeds of the upper and lower regions of the heat exchanger 1. In addition, increasing the number of wind speed detection devices 4 can also increase the accuracy of detection and judgment.

[0055] like Figure 2 and Figure 3 As shown, the cross-sectional shape of the heat exchanger 1 of the general air conditioner outdoor unit is U-shaped or G-shaped. Among them, the U-shaped heat exchanger 11 has three heat exchange surfaces; the G-shaped heat exchanger 12 has four heat exchange surfaces. The upper and lower areas of each heat exchange surface can be installed with a wind speed detection device 4 for detection and judgment.

[0056] Optionally, the wind speed regulating device 3 includes a plurality of guide vanes 5 which are evenly distributed at the bottom of the wind circle of the fan 2 along the circumference of the wind circle of the fan 2 and can rotate in a direction perpendicular to the bottom of the wind circle of the fan 2 .

[0057] like Figure 4 The figure shows the initial state of the guide vanes 5, at which the opening angle of all the guide vanes 5 is 90°. In this state, the wind resistance generated by the guide vanes 5 is minimal, and the wind entering through different surfaces of the heat exchanger 1 is guided and combed, and the wind entering from different directions is guided, so as to achieve the purpose of reducing wind resistance and turbulent noise.

[0058] like Figure 5As shown, the guide vanes 5 are in a fully closed state, which is the maximum adjustment state where the guide vanes 5 gradually reduce their angles from the initial state, and can maximize the wind speed in the lower area of ​​the heat exchanger 1 and reduce the wind speed in the upper area. In this state, all the guide vanes 5 form an integral closed guide ring, and the guide vanes cooperate with each other without air leakage gap problems.

[0059] like Figure 6 As shown, when the wind speed in the upper area of ​​the heat exchanger 1 is high, the opening angle of the guide vanes 5 can be reduced by adjusting all the guide vanes 5 to rotate clockwise or counterclockwise to reduce the gap between adjacent guide vanes 5, and the wind resistance near the upper area of ​​the heat exchanger 1 can be increased, thereby reducing the wind speed in the upper area of ​​the heat exchanger 1. Under the condition of the same air volume, the wind speed in the lower area of ​​the heat exchanger 1 can be increased, thereby improving the heat exchange efficiency in the lower area of ​​the heat exchanger 1. When the wind speed in the lower area of ​​the heat exchanger 1 is high, the opening angle of the guide vanes 5 can be increased accordingly to increase the gap between adjacent guide vanes 5, reduce the wind resistance in the upper area, and increase the wind speed in the upper area.

[0060] like Figure 7 As shown, in order to achieve more accurate detection and control of different heat exchange surface areas of the heat exchanger 1, taking the G-type heat exchanger 12 as an example, all guide vanes 5 are divided into four partitions according to the four heat exchange surfaces to form four independent guide vane 5 devices, and four motors are set to drive the four guide vane 5 devices. Different partitions adjust the guide vanes 5 corresponding to their respective areas according to the analysis results of the wind speed detection device 4, thereby improving the heat exchange efficiency of the heat exchanger 1.

[0061] like Figure 8 As shown, optionally, the air conditioner further includes a control processor 6, which is composed of a variety of components and is an electronic control processing unit that can receive the wind speed data transmitted by the wind speed detection device 4 and perform real-time verification according to a predetermined logic.

[0062] If the detected data is within the set reasonable range, it is considered that the heat exchange wind speed of the air conditioner outdoor unit heat exchanger 1 is operating normally and conforms to the logic of normal operation; if it is abnormal, the corresponding regulating device action and adjustment improvement are performed according to the logic setting.

[0063] Optionally, the air conditioner further comprises a warning device 7, which is composed of components such as an indicator light and a whistle alarm, and can be set to have light alarm and whistle alarm functions. When a fault occurs in the air conditioner heat exchanger 1, the control processor 6 instructs the warning device 7 to give a corresponding warning.

[0064] The warning device 7 can be set in the user terminal, for example, in the air conditioner wire controller in the room, and remind when there are abnormal conditions such as dirt, blockage, and obstruction on the surface of the heat exchanger 1. The warning device 7 can also be set in the electric control box of the air conditioner outdoor unit, and integrated on the display panel, and the reminder is displayed by a warning light.

[0065] Optionally, the air conditioner further comprises a linkage implementation device 8, which is used to receive an action instruction issued by the control processor 6 and adjust the rotation speed of the wind speed adjustment device 3 and the fan 2 according to a preset logical action.

[0066] When the heat exchange efficiency of the heat exchanger 1 is seriously abnormal, the wind speed regulating device 3 and the fan 2 can be adjusted in conjunction, and the two adjustment schemes are carried out simultaneously to monitor the operating status of the heat exchanger and adjust and optimize it to achieve the most efficient heat exchange effect.

[0067] Optionally, the air conditioner further includes a big data cloud service platform 9, which transmits information and instructions through the Internet and servers, cloud service platforms, maintenance personnel terminals, etc. The data collected by the control processor 6 can be transmitted to the terminal, and the instructions issued by the terminal can also be transmitted to the control processor 6 to complete the operation of the corresponding instructions and realize two-way communication.

[0068] The big data cloud service platform 9 can receive the data transmitted by the control processor 6, and transmit instructions and perform maintenance through background operations or reminders to after-sales personnel, such as cleaning the dirt, blockages and obstructions on the surface of the heat exchanger 1 to keep the surface of the heat exchanger 1 clean and the air flow smooth. In addition, a warning device 7 can also be set on the big data cloud service platform 9 to notify the monitoring personnel or after-sales personnel through corresponding information push and SMS.

[0069] In combination with the above air conditioner, Fig. 9 As shown, the embodiment of the present disclosure also provides a method for an air conditioner, comprising:

[0070] S001: The processor obtains a first wind speed detected by a first wind speed detection device and a second wind speed detected by a second wind speed detection device.

[0071] S002: If the first wind speed and the second wind speed do not satisfy a first preset condition, the processor adjusts the wind speed regulating device until the first wind speed and the second wind speed satisfy the first preset condition.

[0072] The first wind speed detection device obtains the wind speed of the upper area of ​​the air conditioner, and the second wind speed detection device obtains the wind speed of the lower area of ​​the air conditioner. The first wind speed and the second wind speed are analyzed. When the analysis result meets the first preset condition, it means that the heat exchange efficiency of the upper and lower areas inside the air conditioner is close, which conforms to the normal operation logic; when the analysis result does not meet the first preset condition, it is necessary to adjust the wind speed adjustment device and perform real-time detection of the wind speed until the analysis result meets the first preset condition.

[0073] Optionally, the first wind speed and the second wind speed do not meet the first preset condition, including: |v1-v2|>V1 for a duration of T1, or, v min <V2 duration reaches T1.

[0074] Where v1 is the first wind speed; v2 is the second wind speed; V1 is the first threshold; T1 is the preset time; v min It is the smaller of v1 and v2; V2 is the second threshold.

[0075] Optionally, the value range of V1 is [2 m / s, 3 m / s]. More specifically, V1 = 2 m / s, 2.5 m / s or 3 m / s.

[0076] Optionally, the value range of T1 is [20 min, 50 min]. More specifically, T1=30 min, 35 min or 40 min.

[0077] Optionally, the value range of V2 is [2 m / s, 3 m / s]. More specifically, V1 = 2 m / s, 2.5 m / s or 3 m / s.

[0078] In practical applications, V1=2m / s, T1=30min, V2=2m / s can be set. If the wind speed difference between the upper and lower areas is greater than V1 during the T1 time, it means that the difference in heat exchange efficiency between the upper and lower areas is large, and the problem of the heat exchanger not being able to perform at its most efficient performance may occur due to the difference in heat exchange efficiency. When the wind speed in a part of the area is less than V2, it means that the heat exchange efficiency of the area is low, which will affect the heat exchange performance of the heat exchanger as a whole, and may even cause a certain degree of damage to the heat exchanger device due to the excessively high temperature in the area.

[0079] Optionally, adjusting the wind speed regulating device includes: if v1<v2, adjusting the guide vane angle to increase the gap between adjacent guide vanes and increase the wind speed entering the fan wind ring; if v1>v2, adjusting the guide vane angle to reduce the gap between adjacent guide vanes and reduce the wind speed entering the fan wind ring.

[0080] Optionally, the first wind speed and the second wind speed satisfy a first preset condition, including: |v1-v2|≤V1, and, v min>V2.

[0081] The angle of the guide vane is adjusted by the processor controlling the rotation of the stepper motor. The stepper motor drives the angle of the guide vane adjustment shaft to balance the wind speed in the upper and lower areas of the heat exchanger. The main purpose of adjusting the guide vane is to change the wind speed in the air inlet area of ​​the upper heat exchanger. If the wind speed in the upper area is large, the guide vane angle is reduced to reduce the gap between adjacent guide vanes and increase wind resistance. When the total air volume remains unchanged, the wind speed in the upper area is reduced and the wind speed in the lower area is increased. The effective heat exchange area is moved downward as much as possible to improve the heat exchange efficiency of the lower heat exchanger. When the wind speed in the upper area is low, the guide vane angle is increased to increase the gap between adjacent guide vanes and reduce wind resistance. When the total air volume remains unchanged, the wind speed in the upper area is increased and the wind speed in the lower area is reduced.

[0082] Optionally, during the process of adjusting the guide vane angle, it can be adjusted 1° at a time, and the wind speed can be detected in real time until the test data meets the optimal logical data range. The angle adjustment is stopped and the current angle is maintained unchanged. The air conditioner outdoor unit operates with the adjusted guide vane angle.

[0083] like Fig.10 As shown, the embodiment of the present disclosure provides another method for an air conditioner, comprising:

[0084] S101: The processor obtains a first wind speed detected by a first wind speed detection device and a second wind speed detected by a second wind speed detection device.

[0085] S102: If the first wind speed and the second wind speed do not meet the first preset condition, the processor determines that it is a warning operation and controls the indicator light to give a prompt.

[0086] S103: The processor adjusts the wind speed regulating device until the first wind speed and the second wind speed meet a first preset condition.

[0087] When the air conditioner is operating abnormally, the warning device can give a reminder through an indicator light on the air conditioner wire controller in the room, or on the electrical control box of the air conditioner outdoor unit, so that the user can contact after-sales personnel for maintenance in time, thereby improving the user experience.

[0088] like Fig.11 As shown, the embodiment of the present disclosure provides another method for an air conditioner, comprising:

[0089] S201: The processor obtains a first wind speed detected by a first wind speed detection device and a second wind speed detected by a second wind speed detection device.

[0090] S202, the processor determines whether the first wind speed and the second wind speed meet the first preset condition, if so, executes step S201, if not, executes step S203.

[0091] S203, the processor determines whether the first wind speed and the second wind speed meet the second preset condition, if not, executes step S204, and if so, executes step S205.

[0092] S204: The processor adjusts the wind speed regulating device until the first wind speed and the second wind speed meet a first preset condition.

[0093] S205, the processor adjusts the wind speed regulating device and the fan speed.

[0094] S206, if after T1 minutes of continuous detection and adjustment, the first wind speed and the second wind speed still meet the second preset condition, the processor reminds the after-sales service to check the heat exchanger of the air conditioner outdoor unit.

[0095] Optionally, the second preset condition includes: |v1-v2|>V1', or, v min <V2'.

[0096] Wherein, V1' is the third threshold, and V1'>V1; V2' is the fourth threshold, and V2'<V2.

[0097] Optionally, V1' is 1 m / s greater than V1; or, V1' is 1.5 m / s greater than V1.

[0098] Optionally, V2' is 1 m / s smaller than V2; or, V2' is 0.5 m / s larger than V2.

[0099] Optionally, controlling the fan to increase the speed includes: a single adjustment to increase the speed range is [10rpm, 30rpm], and an upper limit value of the fan speed adjustment is 10% of the rated speed.

[0100] Optionally, a single adjustment increases the speed range by 15 rpm, 20 rpm, or 25 rpm.

[0101] If the wind speed in the upper and lower areas of the heat exchanger seriously exceeds the normal range, it means that the heat exchanger is in an abnormal operating state. At this time, after adjusting the wind speed adjustment device, if the analysis result between the first wind speed and the second wind speed is still beyond the normal value range, the fan speed needs to be adjusted. In order to ensure that the performance of the machine and the user's experience do not drop sharply and do not cause damage to the fan at high speed, the speed can be increased by 20rpm each time. In addition, it is also necessary to promptly notify after-sales personnel to conduct inspections of the heat exchange area of ​​the actual heat exchanger, and to conduct inspections and repairs to avoid problems such as low heat exchange efficiency of the air conditioner outdoor unit and poor user experience caused by obstruction of the heat exchanger by foreign objects and dirt.
