Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of air conditioners, and particularly provides an air conditioner and a control method thereof. BACKGROUND

[0002] Summer is the season when mosquitoes breed and multiply. Even if the doors and windows are tightly closed, mosquitoes will inevitably enter the room through the gaps / interstices on the windows (e.g., screen windows) and at the moment when the doors are opened / closed, affecting the user's home experience.

[0003] In view of the above situation, some air conditioner indoor units currently have a mosquito trapping device arranged inside. During use of the air conditioner, the mosquito trapping device traps, kills and collects mosquitoes. However, the mosquito trapping device currently has poor mosquito trapping effect and cannot attract mosquitoes at a position far away from the air conditioner. SUMMARY

[0004] An object of the application is to solve the problem of poor mosquito trapping effect of the mosquito trapping device on the existing air conditioner.

[0005] To overcome the above technical problems, the inventors of the application have creatively found that mosquitoes have very sensitive sensing ability to changes in airflow. When the air flow of the air conditioner changes in speed, the flight area of the mosquitoes will suddenly change compared to when the air flow of the air conditioner maintains a constant speed. Moreover, the mosquitoes tend to fly to an area with less airflow change. Based on this creative finding of the inventors, the application provides, in a first aspect, a control method of an air conditioner, the air conditioner comprising a mosquito trapping device, the control method comprising:

[0006] obtaining a target area where a user is located;

[0007] obtaining a current direction of air flow blown by the air conditioner;

[0008] determining whether the current direction is directed to the target area;

[0009] if the current direction is not directed to the target area, controlling the air conditioner to change the speed of the air flow at a preset frequency to interfere with the flight of the mosquitoes and to make the air pressure at the air inlet of the air conditioner attract the mosquitoes into the mosquito trapping device.

[0010] Optionally, the controlling the air conditioner to change the speed of the air flow at a preset frequency comprises:

[0011] controlling the air conditioner to change between a first speed and a second speed at a preset frequency;

[0012] wherein the first speed is greater than the second speed.

[0013] Optionally, the controlling the air conditioner to transform between the first wind speed and the second wind speed at a preset frequency comprises:

[0014] The air conditioner is controlled to alternately run at the first wind speed for m time lengths and at the second wind speed for n time lengths.

[0015] Optionally, the first wind speed is a sum of a preset wind speed and a compensation wind speed, and the second wind speed is a difference between the preset wind speed and the compensation wind speed.

[0016] Optionally, the first wind speed V1 and the second wind speed V2 are determined by the following formulas respectively:

[0017]

[0018] wherein, V i is a preset wind speed, V 大 is a maximum wind speed of the air conditioner wind, and V 小 is a minimum wind speed of the air conditioner wind.

[0019] Optionally, the control method further comprises:

[0020] If the current direction points to the target area, the air conditioner is controlled to run at a preset wind speed.

[0021] Optionally, the obtaining the target area where the user is located comprises:

[0022] Obtaining a target position where the user is located;

[0023] Determining a distance between the air conditioner and the target position;

[0024] According to the distance and a preset wind speed of the air conditioner, determining an elapsed time for the air conditioner wind to blow to the target position;

[0025] According to the elapsed time and an oscillation speed of a deflector of the air conditioner, determining the target area, so that the wind speed of the air conditioner wind blowing to the target position is the preset wind speed.

[0026] The present application provides an air conditioner in the second aspect, comprising an air conditioner outdoor unit, an air conditioner indoor unit, a mosquito trapping device installed on the air conditioner indoor unit and a controller, the controller is configured to control the air conditioner to execute the control method of any one of the first aspect.

[0027] Optionally, the mosquito trapping device comprises:

[0028] A shell is configured with an inlet;

[0029] A mosquito lamp is used to attract mosquitoes into the shell;

[0030] a mosquito-killing component disposed in the housing and having a photocatalyst coating;

[0031] a driving device configured to drive the mosquito-killing component to press the mosquito in the housing to kill the mosquito.

[0032] Optionally, the mosquito-killing component comprises a fixed net plate and a movable net plate, the fixed net plate is fixedly connected with the housing, the movable net plate is pivotally connected with the fixed net plate through an end thereof away from the inlet, and the movable net plate is drivingly connected with the driving device through an end thereof close to the inlet.

[0033] Based on the foregoing description, those skilled in the art can understand that, in the foregoing technical solutions of the present application, when the current direction of the air conditioner air is not directed to the target area where the user is located, the air conditioner is caused to change the air speed at a preset frequency, so that the mosquito can quickly perceive the change of the airflow, and then change the flight area to fly to an area where the airflow is more gentle and stable. The return air inlet of the air conditioner meets the condition and is more likely to attract mosquitoes, thereby realizing the trapping of mosquitoes by the mosquito trapping device at a position far away from the air conditioner.

[0034] Further, when the current direction is directed to the target area, the air conditioner is controlled to operate at a preset air speed, which ensures the effect of the air conditioner air blowing to the user and ensures the air blowing experience of the user.

[0035] Still further, the target position where the user is located is acquired, then the distance between the air conditioner and the target position is determined, and then the elapsed time of the air conditioner air blowing to the target position is determined according to the distance and the preset air speed of the air conditioner. Finally, the target area is determined according to the elapsed time and the swing speed of the air deflector of the air conditioner, so that the air speed of the air conditioner air blowing to the target position is the preset air speed. As can be seen, the air speed of the air conditioner air has been changed back to the preset air speed before blowing to the user, avoiding the influence on the air blowing experience of the user when the air speed of the air conditioner air has not been changed back to the preset air speed when blowing to the user.

[0059] The air conditioner indoor unit 100 in the present application will be illustrated below with reference to Figures 2 to 9 . Among them, Figure 2 is a cross-sectional view of the air conditioner indoor unit 100 in one example of the present application, Figure 3 is an isometric view of the mosquito trapping device 150 (the mosquito killing member 153 is opened) in one example of the present application, Figure 4 is a schematic view of the photocatalytic coating 155 in one example of the present application, Figure 5 is a structural schematic view of the mosquito killing member 153 in one example of the present application, Figure 6 is Figure 3 a cross-sectional view of the mosquito trapping device 150 along the A-A direction in one example of the present application, Figure 7 is an isometric view of the mosquito trapping device 150 (the mosquito killing member 153 is closed) in one example of the present application, Figure 8 is Figure 7 a cross-sectional view of the mosquito trapping device 150 along the A-A direction in one example of the present application, Figure 9 is a structural schematic view of the mosquito trapping device 150 in another example of the present application, Figure 10 is Figure 9 a cross-sectional view of the mosquito trapping device 150 along the B-B direction in one example of the present application.

[0060] As shown in Figure 2 , in one example of the present application, the air conditioner indoor unit 100 comprises a casing 110, a heat exchanger 120, a fan 130, a guide vane 140, and a mosquito trapping device 150.

[0061] Continuing to refer to Figure 2 , the casing 110 is provided with an air inlet 111 and an air outlet 112, so that the air outside the casing 110 enters the casing 110 from the air inlet 111, and the air inside the casing 110 flows out of the casing 110 from the air outlet 112.

[0062] With reference to Figure 2 , the heat exchanger 120 is arranged inside the casing 110, and is used to heat or cool the air inside the casing 110. When the air conditioner indoor unit 100 is in cooling mode, the heat exchanger 120 is used as an evaporator to cool the air inside the casing 110. When the air conditioner indoor unit 100 is in heating mode, the heat exchanger 120 is used as a condenser to heat the air inside the casing 110.

[0063] With reference to Figure 2 , the fan 130 is arranged inside the casing 110, and is used to drive the air outside the casing 110 to enter the casing 110 from the air inlet 111, and to drive the air inside the casing 110 to flow out of the casing 110 from the air outlet 112.

[0064] With reference to Figure 2 , the air deflector 140 is mounted on the casing 110 at the air outlet 112, and is used to guide the blowing direction of the air blown out of the casing 110.

[0065] With reference to Figure 2 , the mosquito trapping device 150 is arranged inside the casing 110, and is used to trap, kill and contain mosquitoes. Further, the mosquito trapping device 150 is arranged at the air inlet 111 of the casing 110, i.e. the mosquito trapping device 150 is close to the air inlet 111 of the casing 110, so that the mosquito trapping device 150 can attract mosquitoes by means of the negative pressure generated when the fan 130 rotates.

[0066] In addition, in other embodiments of the present application, the skilled in the art can arrange the mosquito trapping device 150 at any other feasible position according to the needs. For example, the mosquito trapping device 150 can be arranged at the top side, front side, left side or right side of the casing 110.

[0067] The mosquito trapping device 150 in one example of the present application will be described in detail below with reference to Figures 3 to 8 .

[0068] As shown in Figure 3 , in one example of the present application, the mosquito trapping device 150 comprises a housing 151, a mosquito attracting lamp 152, a mosquito killing member 153 and a driving device 154.

[0069] With reference to Figure 3 , the housing 151 is configured with an inlet 1511, so that the mosquitoes attracted by the mosquito trapping device 150 enter the housing 151 from the inlet 1511.

[0070] Further, the inlet 1511 is formed at the top end of the shell 151, and the bottom of the shell 151 is provided with at least one air outlet 1512, so that when the fan 130 is running, a flowing air current is formed in the shell 151, thereby attracting mosquitoes into the shell 151.

[0071] In addition, in other embodiments of the present application, the skilled in the art can also omit the setting of the air outlet 1512 as needed.

[0072] As shown in Figure 3 , the mosquito attractor 152 is arranged in the shell 151. And, the mosquito attractor 152 is preferably an ultraviolet lamp.

[0073] The skilled in the art can understand that the ultraviolet lamp not only has the function of attracting mosquitoes, but also has the function of sterilization.

[0074] As shown in Figure 4 , in an example of the present application, the mosquito killing member 153 is arranged in the shell 151 and has a photocatalyst coating 155, which can be titanium dioxide, or any feasible material such as zinc oxide, tin oxide, zirconium dioxide, cadmium sulfide, etc.

[0075] Optionally, the inner surface of the shell 151 is also provided with the photocatalyst coating 155 to improve the sterilization capability of the mosquito trapping device 150.

[0076] As shown in Figure 5 , in an example of the present application, the mosquito killing member 153 includes a fixed mesh plate 1531 and a movable mesh plate 1532. The fixed mesh plate 1531 and / or the movable mesh plate 1532 is provided with the photocatalyst coating 155. Further, the fixed mesh plate 1531 and the movable mesh plate 1532 are both distributed with a plurality of mesh holes to increase the area of the photocatalyst layer and improve the sterilization effect of the mosquito trapping device 150.

[0077] As shown in Figure 5 and Figure 6 , the fixed mesh plate 1531 is fixedly connected with the shell 151. Optionally, the fixed mesh plate 1531 has a gap between the side wall of the shell 151 to allow air flow, thereby avoiding the carcass of the killed mosquitoes from being stuck between the mesh wire of the fixed mesh plate 1531 and the shell 151.

[0078] Continuing to refer to Figure 5 and Figure 6 , the movable mesh plate 1532 is arranged in the shell 151 and is movable relative to the shell 151.The movable net plate 1532 is pivotally connected to the fixed net plate 1531 at an end thereof away from the inlet 1511, and is drivingly connected to the driving device 154 at an end thereof close to the inlet 1511. Alternatively, the person skilled in the art can drivingly connect the movable net plate 1532 to the driving device 154 at other parts (e.g. the middle part) thereof according to the need.

[0079] With reference to Figure 5 and Figure 6 , the movable net plate 1532 is provided with a sliding groove 15321 perpendicular to the rotation direction of the movable net plate 1532, so that the movable net plate 1532 is drivingly connected to the driving device 154 through the sliding groove 15321.

[0080] Further, the movable net plate 1532 is provided with a sliding rail for defining the sliding groove 15321.

[0081] In addition, in other embodiments of the present application, the person skilled in the art can omit the fixed net plate 1531 according to the need, and pivotally connect the movable net plate 1532 to the shell 151, and extrude the mosquitoes together with the shell 151.

[0082] As shown in Figure 3 and Figure 6 , the mosquito attractor 152 is arranged on the inner side wall of the shell 151 facing the movable net plate 1532. That is, the mosquito attractor 152 is arranged on the right side wall of the shell 151 in the figure.

[0083] Further, since the killed mosquitoes are prone to accumulate at the bottom between the movable net plate 1532 and the fixed net plate 1531 under the action of gravity. Therefore, the mosquito attractor 152 can be arranged at the middle or bottom of the shell 151, so as to irradiate the mosquitoes and kill bacteria.

[0084] In addition, in other embodiments of the present application, the person skilled in the art can arrange the mosquito attractor 152 at other positions according to the need, for example, on the bottom wall of the shell 151, or at a position opposite to the inlet 1511 of the shell 151.

[0085] As shown in Figure 5 and Figure 6 , the driving device 154 comprises a motor 1541 fixedly connected to the shell 151, and a driving member 1542 fixedly connected to the rotating shaft of the motor 1541, and an end of the driving member 1542 away from the motor 1541 is movably connected to the movable net plate 1532.

[0086] Further, the shell 151 is provided with a through hole (not shown in the figure) allowing the rotating shaft of the motor 1541 to pass through, so that the shell of the motor 1541 is fixed to the outside of the shell 151, the rotating shaft of the motor 1541 passes through the shell 151, and is fixedly connected with the driving member 1542 arranged inside the shell 151.

[0087] As shown in Figure 5 and Figure 6 , in one example of the present application, the driving member 1542 is a disc-shaped member, and includes a cylindrical sliding block 15421 embedded in the sliding groove 15321, so as to achieve the active connection of the driving member 1542 with the movable mesh plate 1532.

[0088] As can be seen from Figure 6 and Figure 8 , with the rotation of the motor 1541, the driving member 1542 drives the movable mesh plate 1532 to swing reciprocally, and thus causes the movable mesh plate 1532 to jointly press the mosquitoes between the movable mesh plate 1532 and the fixed mesh plate 1531, and thus kills the mosquitoes.

[0089] In addition, in other embodiments of the present application, those skilled in the art can also set the driving member 1542 to be any other feasible member according to the needs, for example, a rod-shaped structure or a cam with the sliding block 15421.

[0090] The working principle of the mosquito trapping device 150 in the present application will be briefly described below with reference to Figures 3 to 8 , and in particular with reference to Figure 6 and Figure 8 .

[0091] First, when the air conditioner indoor unit 100 is in cooling, the motor 1541 drives the movable mesh plate 1532 to move to the position shown in Figure 6 . Then, the mosquito lamp 152 is powered on, so as to attract mosquitoes to enter the entrance 1511 of the shell 151 through the air inlet 111 of the casing 110, and fall between the movable mesh plate 1532 and the fixed mesh plate 1531. Subsequently, the motor 1541 is controlled to rotate, so as to cause the movable mesh plate 1532 to swing reciprocally, and thus cause the movable mesh plate 1532 to jointly press and kill the mosquitoes with the fixed mesh plate 1531.

[0092] Those skilled in the art can understand that when the movable mesh plate 1532 moves to the position shown in Figure 6 , the mosquito lamp 152 has a better irradiation effect on the photocatalytic coating 155 on the movable mesh plate 1532 and the fixed mesh plate 1531, and is more likely to excite the photocatalytic coating 155 to decompose organic compounds and kill bacteria.

[0093] Optionally, the mosquito trapping device 150 further includes a first position sensor and an optional second position sensor. The first position sensor is used to detect whether the movable mesh panel 1532 has moved to... Figure 6 The position is indicated so that motor 1541 stops rotating. A second position sensor is used to detect whether the movable mesh plate 1532 has moved to the indicated position. Figure 8 The location shown.

[0094] Optionally, a flexible barrier is provided between the top of the movable mesh panel 1532 and the side wall of the outer casing 151 facing thereto to prevent mosquitoes from entering the movable mesh panel 1532. Figure 8 When it falls into the movable mesh plate 1532 at the position shown. Figure 8 Between the right side walls of the inner shell 151.

[0095] Based on the foregoing description, those skilled in the art will understand that, in one example of the present invention, the mosquito-killing component 153 is driven by the driving device 154 to squeeze the mosquitoes inside the outer casing 151, thereby achieving the purpose of killing the mosquitoes; by providing a photocatalytic coating 155 on the mosquito-killing component 153, the mosquito trapping device 150 can sterilize the killed mosquitoes through the photocatalytic coating 155, preventing bacteria from multiplying using mosquitoes as nutrients. Therefore, the air conditioner indoor unit 100 of the present invention effectively inhibits the growth of bacteria in the mosquito trapping device 150, thereby ensuring the health of users.

[0096] Furthermore, the photocatalytic coating 155 can sterilize areas that are not illuminated by the mosquito-attracting lamp 152, ensuring the sterilization efficiency of the mosquito trapping device 150.

[0097] At the same time, since photocatalysts can decompose organic compounds, they can also decompose mosquitoes after they have been killed, reducing the total number of mosquitoes in the mosquito trapping device 150, thereby reducing the frequency of cleaning the mosquito trapping device 150 by the user.

[0098] Furthermore, provided that the mosquito trapping device 150 can capture and kill mosquitoes, those skilled in the art can also configure the mosquito trapping device 150 into any other feasible structure as needed.

[0099] For example, such as Figure 9 and Figure 10 As shown in another example, the mosquito trapping device 150 may consist only of the housing 151, the mosquito-attracting lamp 152, and the fixing mesh 1531 described above. The fixing mesh 1531 is fixed to the housing 151 at an angle. Air vents 1512 are provided on one side of the fixing mesh 1531, on the front or rear side wall of the housing 151, and on the bottom wall, to create airflow within the housing 151 and thus generate negative pressure to attract mosquitoes.

[0100] Further, the fixed net plate 1531 is electrified with high voltage to electrocute the mosquitoes, so as to kill the mosquitoes.

[0101] Of course, in the example shown in Figure 9 and Figure 10 , the mosquito trapping device 150 can further include a photocatalyst coating 155 arranged on the shell 151 and / or the mosquito lamp 152.

[0102] The control method of the air conditioner will be described in detail below with reference to the air conditioner described above.

[0103] Before that, it should be noted that the control method described below is not only applicable to the air conditioner with the mosquito trapping device 150 described above, but also applicable to the air conditioner with any other form of mosquito trapping device 150.

[0104] As shown in Figure 11 , in some embodiments of the present application, the control method of the air conditioner includes:

[0105] Step S100, obtaining a target area where a user is located.

[0106] As shown in Figure 12 , step S100 further includes steps S110 to S140, which are specifically as follows:

[0107] Step S110, obtaining a target position where the user is located.

[0108] In some embodiments of the present application, the air conditioner can obtain the current position of the user in any feasible manner.

[0109] For example, an infrared sensor or an infrared camera is arranged on the indoor unit 100 of the air conditioner to obtain the user in the room through the infrared sensor or the infrared camera, and then determine the orientation and distance of the user relative to the indoor unit 100 of the air conditioner. The orientation and distance are the current position of the user.

[0110] In some embodiments of the present application, if there is one user in the room, the obtained current position is one. If there are multiple users in the room, the obtained current position can be multiple.

[0111] Step S120, determining the distance between the air conditioner and the target position.

[0112] As described above, the user in the room can be obtained through the infrared sensor or the infrared camera, and the orientation and distance of the user relative to the indoor unit 100 of the air conditioner can be determined.

[0113] In addition, the distance between the air conditioner and the target location can be determined by distance sensors (such as radar, infrared range sensors, etc.).

[0114] Step S130: Determine the time t it takes for the air conditioner to blow air towards the target location based on the distance and the preset wind speed of the air conditioner.

[0115] The preset wind speed is the wind speed set by the user via a remote control or other terminal. For example, it can be high wind, low wind, or medium wind.

[0116] Furthermore, after receiving the instruction from the user, the air conditioner will determine the speed of the fan 130 inside the air conditioner according to the instruction, and then make the fan 130 at that speed output the air conditioner air at the preset speed.

[0117] Furthermore, the specific values ​​of different preset wind speeds can be stored in advance on the air conditioner; alternatively, a wind speed sensor can be installed at the air outlet 112 to detect the current preset wind speed.

[0118] In step S130, the time t is equal to the distance divided by the preset wind speed.

[0119] Step S140: Based on the elapsed time t and the swing speed of the air conditioner's air guide plate 140, determine the target area so that the wind speed when the air conditioner blows towards the target location is the preset wind speed.

[0120] The oscillation speed of the air guide plate 140 can be determined by the manufacturer through experiments before the air conditioner leaves the factory and stored in the air conditioner. The oscillation speed of the air guide plate 140 can also be detected by equipping the air conditioner with an angle sensor.

[0121] like Figure 13 As shown, in step S140, the air guide plate 140 along Figure 13 The middle arrow indicates a counter-clockwise direction, extending from the current oscillation speed over time t, into the direction of the oscillation range. Figure 13 Within the target area on the left side. The air guide plate 140... Figure 13 The clockwise direction indicated by the middle arrow falls in the direction of the extension of the oscillation range over time t at the current oscillation speed. Figure 13 Within the target area on the right side of the middle.

[0122] It should be noted that the air guide plate 140 can be Figure 2 The horizontal air guide plate 140 shown, with its rotating axis parallel to the horizontal direction, can also be a vertical air guide plate 140 not shown in the figure.

[0123] Furthermore, in other embodiments of the present invention, those skilled in the art may, as needed, use the target location as the center of the target area, and...Figure 13 The target area on the left side of the target position and the target area on the right side of the target position are merged into one target area.

[0124] In step S200, the current direction of the air-conditioning air blown by the air conditioner is obtained.

[0125] In some embodiments of the present application, an angle (position) sensor for detecting the swing angle (position) of the deflector 140 is arranged on the air conditioner indoor unit 100 to detect the current position of the deflector 140, so as to determine the current blowing direction of the air conditioner according to the current position of the deflector 140.

[0126] In step S300, it is determined whether the current direction of the air-conditioning air points to the target area.

[0127] In the present application, any feasible way can be used to determine whether the current direction points to the target area. For example, a space model is established for the target area determined in step S100 and the position of the air conditioner, so as to determine the relative position of the target area and the air conditioner in the space model. Then the current direction of the air-conditioning air is input into the model, so as to determine whether the current direction of the air-conditioning air points to the target area.

[0128] In step S400, if the current direction points to the target area, the air conditioner is controlled to run at a preset wind speed.

[0129] As understood by those skilled in the art, by controlling the air conditioner to run at a preset wind speed when the current direction points to the target area, the effect of the air-conditioning air blowing to the user is ensured, and the air-conditioning experience of the user is ensured. Especially in the process of air conditioning cooling, when the preset wind speed is small, the user is prevented from catching a cold due to high air-conditioning air speed.

[0130] In step S500, if the current direction does not point to the target area, the air conditioner is controlled to change the wind speed at a preset frequency to interfere with the flight of mosquitoes and attract mosquitoes into the mosquito trapping device 150 at the air inlet 111 of the air conditioner.

[0131] The "controlling the air conditioner to change the wind speed at a preset frequency" can include controlling the air conditioner to continuously change or intermittently change between multiple wind speeds.

[0132] Step S500 further includes controlling the air conditioner to change between a first wind speed and a second wind speed at a preset frequency. The first wind speed is greater than the second wind speed.

[0133] Further, the air conditioner is controlled to alternately run at the first wind speed for m time lengths and at the second wind speed for n time lengths.

[0134] The m and n can be any feasible numerical value, for example, m is 1S, 2S, 5S, 10S, etc., and n is 1S, 2S, 3S, 7S, etc.

[0135] Further, the first air speed and the second air speed can be any feasible values.

[0136] As an example one, the first air speed is the sum of the preset air speed and the compensation air speed, i.e., the first air speed = preset air speed + compensation air speed; the second air speed is the difference between the preset air speed and the compensation air speed. Wherein, the compensation air speed can be any feasible value, i.e., the first air speed = preset air speed - compensation air speed. Wherein, the compensation air speed can be any value, for example, 10%, 15%, 20%, 30% of the preset air speed, etc.

[0137] If the fan 130 speed corresponding to the preset air speed is denoted as X i r / min, the fan 130 speed corresponding to the first air speed is denoted as X1 r / min, and the fan 130 speed corresponding to the second air speed is denoted as X2 r / min. Then, X1 = X i +△S, and X2 = X i -△S.

[0138] As an example two, the first air speed V1 and the second air speed V2 are determined by the following formulas respectively:

[0139]

[0140]

[0141] Wherein, V i is the preset air speed, V 大 is the maximum air speed of the air conditioner, and V 小 is the minimum air speed of the air conditioner.

[0142] Similarly, if the fan 130 speed corresponding to the maximum air speed is denoted as X 大 r / min, and the fan 130 speed corresponding to the minimum air speed is denoted as X 小 r / min, then the formula (1) can be transformed into the following formula (3), and the formula (2) can be transformed into the following formula (4):

[0143]

[0144] It can be understood by those skilled in the art that in the example two, the first air speed V1 can be smaller when the preset air speed is larger, and can be larger when the preset air speed is smaller; the second air speed V2 can be larger when the preset air speed is larger, and can be smaller when the preset air speed is smaller; which ensures the cooling rate and the heating rate of the air conditioner to the room.

[0145] Based on the foregoing description, those skilled in the art can understand that when the current direction of the air conditioner wind is not directed to the target area where the user is located, the mosquito can quickly perceive the change of the airflow by making the air conditioner change the wind speed at a preset frequency, thereby changing the flight area and flying to the area where the airflow is more gentle and stable. The return air inlet of the air conditioner meets the condition and is more likely to attract mosquitoes, thereby realizing the trapping of mosquitoes by the mosquito trapping device 150 at a position far away from the air conditioner.

[0146] Further, when the current direction is directed to the target area, by controlling the air conditioner to operate at a preset wind speed, the effect of the air conditioner wind blowing to the user is also ensured, and the air conditioner blowing experience of the user is ensured.

[0147] Further, in the present application, the controller 300 includes a processor (not shown in the figure) and a memory (not shown in the figure). The memory is used to store execution instructions, which are specifically executable computer programs. Further, the execution instructions stored by the memory are set to enable the air conditioner to execute the control method described in any of the foregoing embodiments when executed by the processor.

[0148] Finally, it needs to be pointed out that during the execution of steps S100 to S500, the mosquito trapping device 150 is always in working state, i.e. the mosquito trapping lamp 152 is always on; the motor 1541 can continuously rotate or intermittently rotate; and the fixed net plate 1531 continuously passes high voltage.

[0149] So far, the technical solutions of the present application have been described in combination with the foregoing embodiments, but those skilled in the art can easily understand that the protection scope of the present application is not limited to these specific embodiments. Those skilled in the art can split and combine the technical solutions in each of the above embodiments, or make equivalent changes or replacements to the related technical features, without deviating from the technical principles of the present application. Any changes, equivalent replacements, improvements, etc. made within the technical concept and / or technical principles of the present application will fall within the protection scope of the present application.
