Description

Technical Field

[0001] This application relates to the field of air conditioning technology, and in particular to an air conditioning airflow display device. Background Technology

[0002] Because the flow path and distribution of airflow in space cannot be seen with the naked eye and can only be perceived by touch, users mostly choose air conditioners based on their appearance and performance parameters when purchasing them. While users can directly feel the cooling or heating effect and comfort of the airflow from the indoor unit, different users have different perceptions of airflow, and choosing based on physical sensation may lead to dissatisfaction after purchase. The inability to visually compare and perceive the airflow pattern of an air conditioner may also prevent some wall-mounted air conditioners with excellent airflow comfort from standing out visually.

[0003] In view of the above, this application is hereby submitted. Summary of the Invention

[0004] To address the shortcomings of related technologies, this application provides an air conditioning air field display device that constructs a simulated air field to simulate the air outlet air field when the indoor unit of an air conditioner is in operation. The simulated air field image is superimposed on the indoor unit image of the air conditioner and displayed on the display module, so that users can intuitively view the air outlet effect of the indoor unit of the air conditioner from the display module, thereby realizing the visualization of the air outlet effect of the indoor unit of the air conditioner.

[0005] This application provides an air conditioning airflow display device, comprising:

[0006] The first data acquisition module is used to acquire airflow field information of the indoor unit of the air conditioner during operation;

[0007] The storage module stores simulated air fields, which are constructed based on the air outlet air field information. Multiple simulated air fields are set, and at least some of them are set to correspond to the air outlet air field information of the indoor unit of the air conditioner under different operating conditions.

[0008] The display module is used to display images; the display module is located outside the indoor unit of the air conditioner, and the display module and the outdoor unit of the air conditioner are set independently; a display viewing angle is defined between the display module and the indoor unit of the air conditioner.

[0009] The input module is used to acquire an image of the indoor unit of the air conditioner from the display view.

[0010] The control module is connected to the first acquisition module, the storage module, the display module, and the input module, respectively.

[0011] The control module is configured to: control the first acquisition module to acquire the airflow field information of the air conditioner indoor unit under its current operating status;

[0012] Based on the air field information obtained by the first acquisition module, the corresponding simulated air field is selected from the storage module;

[0014] The control input module receives the acquired image of the air conditioner's indoor unit;

[0015] The simulated wind field image is overlaid with the indoor unit image of the air conditioner obtained by the input module and displayed on the display module.

[0016] This technical solution constructs a simulated airflow field based on the airflow field information of the indoor unit of the air conditioner, simulating the airflow field of the indoor unit during operation. The constructed simulated airflow field is stored in a storage module, and a first acquisition module collects the airflow field information of the indoor unit under its current operating state. The control module then selects the corresponding simulated airflow field from the storage module based on the airflow field information collected by the first acquisition module, and displays the simulated airflow field image on the display module to visualize the airflow effect of the indoor unit. An input module acquires an image of the indoor unit from the user's viewing angle, and also acquires an image of the simulated airflow field from the user's viewing angle. These simulated airflow field images are overlaid on the indoor unit image and displayed on the display module to visualize the distribution of airflow in the space after it exits the air outlet of the indoor unit, allowing the user to intuitively see the airflow effect of the indoor unit.

[0017] In some embodiments, the control module is further configured to: when the indoor unit of the air conditioner switches from the first operating state to the second operating state, update the air outlet field information acquired by the first acquisition module; reselect the simulated wind field from the storage module according to the updated air outlet field information acquired by the first acquisition module, and acquire the simulated wind field image of the reacquired simulated wind field under the display view.

[0018] The reacquired simulated wind field image is overlaid with the indoor unit image of the air conditioner input into the input module and displayed on the display module.

[0019] This technical solution updates the airflow field information acquired by the first acquisition module in a timely manner after the operating status of the indoor unit of the air conditioner changes. Based on the updated airflow field information, it reselects a simulated airflow field from the storage module and overlays the simulated airflow field image and the image of the indoor unit of the air conditioner on the display module. This allows the image displayed on the display module to change in a timely manner according to the operating status of the indoor unit of the air conditioner, ensuring the user's viewing experience.

[0026] The control module is further configured to: control the second acquisition module to input the reference position, and use the reference position as the origin of the air conditioner indoor unit to calculate the display angle formed by the display module and the air conditioner indoor unit.

[0027] This technical solution sets a reference position on the indoor unit of the air conditioner and sets a second acquisition module to acquire the reference position. The reference position is used as the origin of the indoor unit of the air conditioner to calculate the relative positional relationship between the display module and the indoor unit of the air conditioner, thereby calculating the display viewing angle formed by the display module and the indoor unit of the air conditioner.

[0028] In some embodiments, at least the display module, the input module, and the second acquisition module are integrated into the mobile terminal, which is located outside the indoor unit of the air conditioner, and the mobile terminal and the indoor unit of the air conditioner are set up independently of each other.

[0031] In some embodiments, the first acquisition module is communicatively connected to the controller of the indoor unit of the air conditioner; the control module is configured to control the first acquisition module to obtain airflow field information from the controller of the indoor unit of the air conditioner.

[0064] To make the objectives and implementation methods of this application clearer, the exemplary implementation methods of this application will be clearly and completely described below with reference to the accompanying drawings of the exemplary embodiments of this application. Obviously, the exemplary embodiments described are only some embodiments of this application, and not all embodiments.

[0065] It should be noted that the brief descriptions of terms in this application are only for the convenience of understanding the embodiments described below, and are not intended to limit the embodiments of this application. Unless otherwise stated, these terms should be understood in their ordinary and common meaning.

[0066] The terms "first," "second," "third," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar or related objects or entities, and do not necessarily imply a specific order or sequence, unless otherwise specified. It should be understood that such terms are interchangeable where appropriate.

[0067] The terms “include” and “have”, and any variations thereof, are intended to cover but not exclusively include, for example, a product or device that includes a range of components is not necessarily limited to all of the components that are clearly listed, but may include other components that are not clearly listed or that are inherent to such product or device.

[0068] The air conditioning air field display device of this application is applied to the indoor unit of an air conditioner to visualize the air field of the indoor unit, so that users can directly observe the air field of the indoor unit visually and improve the air outlet effect of the indoor unit.

[0069] Air conditioner indoor units can take many forms. For example, they can be wall-mounted air conditioner indoor units with the function of introducing fresh outdoor air, wall-mounted air conditioner indoor units with dehumidification function, or traditional wall-mounted air conditioner indoor units.

[0070] like Figures 1-2 This is a specific embodiment of an air conditioning indoor unit used in the air conditioning air field display device of this application. The air conditioning indoor unit is a wall-mounted air conditioning indoor unit, which includes a housing 100. The housing 100 forms the overall appearance of the air conditioning indoor unit. The top and bottom of the housing 100 are opposite ends, and the height direction of the housing 100 is from the top to the bottom. The left and right sides of the housing 100 are opposite sides, and the length direction of the housing 100 is from the left to the right. The front and rear sides of the housing 100 are opposite sides, and the thickness direction of the housing 100 is from the front to the rear.

[0071] In practical applications, the housing 100 is usually installed in the upper space of an indoor space, with the rear of the housing 100 usually facing the wall and the front of the housing 100 usually facing the user.

[0072] The casing 100 has a heat exchange channel inside, where indoor air is heated to form air conditioning air. The air conditioning air can be cold air, hot air, or even room temperature air.

[0073] The housing 100 includes a housing air inlet 101, which is usually located at the top of the housing 100. The housing air inlet 101 is connected to the heat exchange channel so that indoor air enters the heat exchange channel through the housing air inlet 101.

[0074] The air inlet 101 extends along the length of the housing 100 to give it a large opening size, thereby ensuring the air intake of the indoor unit of the air conditioner.

[0075] The housing 100 includes a housing air outlet 102, which is located on the front side of the housing 100 and near the bottom of the housing 100, that is, the housing air outlet 102 is located on the lower front side of the housing 100. The housing air outlet 102 is connected to the heat exchange channel so that the air conditioning air in the heat exchange channel can be output to the room through the housing air outlet 102.

[0076] The air outlet 102 extends along the length of the housing 100 to give it a larger opening size, thereby ensuring the air volume of the indoor unit of the air conditioner.

[0077] The indoor unit of the wall-mounted air conditioner includes a heat exchanger 400, which is installed on the casing 100 and located in the heat exchange channel. The heat exchanger 400 is used to exchange heat with the air passing through it to form air conditioning air to meet the user's cooling or heating needs.

[0078] The heat exchanger 400 is positioned close to the air inlet 101 of the casing so that the air entering the heat exchange channel can come into contact with the heat exchanger 400 as soon as possible, thereby improving the heat exchange effect of the indoor unit of the wall-mounted air conditioner.

[0079] The indoor unit of the wall-mounted air conditioner includes a heat exchange fan 500, which is installed on the casing 100 and located in the heat exchange channel. The heat exchange fan 500 is located on the side of the heat exchanger 400 away from the air inlet 101 of the casing.

[0080] It should be noted that the heat exchange fan 500 is a cross-flow fan, and the axial direction of the heat exchange fan 500 extends along the length of the casing 100.

[0081] The heat exchange fan 500 operates to draw indoor air into the heat exchange channel through the air inlet 101 of the casing. After heat exchange in the heat exchanger 400, the air is conditioned and then output to the room through the air outlet 102 of the casing.

[0082] like Figure 1 and Figure 2As shown, the wall-mounted air conditioner indoor unit includes an external air guide plate 200, which is located at the air outlet 102 of the unit casing. The external air guide plate 200 is connected to the unit casing 100 in an openable and closable manner to open or close the air outlet 102. By adjusting the rotation angle of the external air guide plate 200, the direction of the air conditioning air output from the air outlet 102 to the room can be adjusted. This prevents the airflow from the air outlet 102 from blowing directly onto people. The external air guide plate 200 rotates around its axis of rotation, which is set along the length of the air outlet 102.

[0083] The indoor unit of the wall-mounted air conditioner includes an inner air guide plate 300, which is used to guide or change the direction of the air conditioning airflow. The inner air guide plate 300 is also used to adjust the air volume of the air conditioning air. The inner air guide plate 300 is rotatably located at the air outlet 102 of the casing. The inner air guide plate 300 is located on the side of the outer air guide plate 200 facing the inside of the casing 100. The inner air guide plate 300 is located between the outer air guide plate 200 and the heat exchange fan 500.

[0084] It should be noted that the distance between the inner air guide plate 300 and the heat exchange fan 500 is less than the distance between the outer air guide plate 200 and the heat exchange fan 500.

[0085] The operation of the heat exchange fan 500 directs the air conditioning air after heat exchange with the heat exchanger 400 to the inner air guide plate 300. The inner air guide plate 300 directs part of the air conditioning air to the air outlet 102 of the casing, and the inner air guide plate 300 directs another part of the air conditioning air to the outer air guide plate 200. The air conditioning air is then directed by the outer air guide plate 200 to the air outlet 102 of the casing.

[0086] In some embodiments, the inner air guide plate 300 guides the air conditioning air to the outer air guide plate 200, and the outer air guide plate 200 guides the direction of the air conditioning air outlet to prevent the air conditioning air from blowing directly on the human body.

[0087] The inner air guide plate 300 rotates around its rotation axis to guide the airflow of the air conditioner or change the direction of the airflow of the air conditioner; the rotation axis of the inner air guide plate 300 is set along the length of the air outlet 102 of the casing.

[0088] The indoor unit of the wall-mounted air conditioner also includes air guide vanes 600. The air guide vanes 600 are located at the air inlet 101 of the casing. There are usually multiple air guide vanes 600. The multiple air guide vanes 600 are distributed along the length of the casing 100 to guide the air conditioning air from the air outlet 102 of the casing to the indoor area and to increase the air outlet range of the air conditioning air.

[0089] The air guide vane 600 rotates along its axis to increase the air outlet range of the air conditioner along the length of the casing 100. The rotation axis of the air guide vane 600 is set to intersect with the length direction and the height direction of the casing 100.

[0090] The outer air guide plate 200 and the inner air guide plate 300 swing roughly up and down relative to the indoor unit of the air conditioner, while the air guide blades 600 swing roughly left and right.

[0091] In this embodiment, the airflow field includes, but is not limited to, the distribution of airflow in the space after it flows out of the air outlet 102 of the casing.

[0092] like Figure 3 As shown, the airflow path and distribution in space cannot be seen with the naked eye and can only be perceived by touch. However, the human body's perception of airflow is affected by the human body's tactile sensitivity and the human body's position. This can easily lead to some high-performance air conditioner indoor units failing to demonstrate their airflow effect well.

[0093] AR (Virtual Reality) technology is a technology that cleverly integrates virtual information with the real world. It simulates and applies computer-generated text, images, 3D models, music, videos, and other virtual information to the real world. The two types of information complement each other, thereby "enhancing" the real world.

[0094] This application applies AR technology to the display of the air outlet effect of an air conditioner indoor unit. By constructing a simulated air field, the air outlet air field of the air conditioner indoor unit is simulated, and the simulated image is displayed on the display module to realize the visualization of the air outlet air field, so that users can view the air outlet effect of the air conditioner indoor unit from the display module.

[0095] The air conditioning air field display device includes a first acquisition module, which is used to acquire the air field information of the air conditioner indoor unit during operation, so as to construct or select a simulated air field based on the air field information of the air conditioner indoor unit in the current operating state.

[0096] Airflow information for an air conditioner typically includes outlet air temperature, outlet air velocity, and outlet air direction. In the indoor unit, the heat exchanger 400 is a crucial component affecting the outlet air temperature, the heat exchange fan 500 is a crucial component affecting the outlet air velocity, and the rotation angles of the outer air guide plate 200, inner air guide plate 300, and guide vanes 600 are crucial components affecting the outlet air direction. Therefore, by obtaining the temperature of the heat exchanger 400, the speed of the heat exchange fan 500, and the rotation angles of the outer air guide plate 200, inner air guide plate 300, and guide vanes 600, the airflow information during the operation of the indoor unit can be obtained.

[0097] In some embodiments of this application, such as Figure 2 and Figure 4 As shown, sensors are installed in the indoor unit of the air conditioner to collect information on the airflow field during the operation of the indoor unit.

[0098] Specifically, such as Figure 4As shown, the first acquisition module includes a temperature sensor 410, which is used to acquire the temperature of the heat exchanger 400 in real time. The output value of the temperature sensor 410 is C1.

[0099] Temperature sensor 410 is installed on or near heat exchanger 400 to ensure the accuracy of information collected by temperature sensor 410.

[0100] The first data acquisition module includes a speed sensor 510, which is used to acquire the rotational speed of the heat exchange fan 500. The output value of the speed sensor 510 is C2.

[0101] In some embodiments, the speed sensor 510 is an infrared acquisition and sensing probe. Based on the number of fan blades, the number of rotations of the heat exchange fan 500 is calculated. The fan speed = number of rotations collected / number of fan blades.

[0102] The first acquisition module includes a first angle sensor 210, which monitors the swing position of the outer air guide plate 200 in real time. The output value of the first angle sensor 210 is C3.

[0103] In some embodiments, the first angle sensor 210 is installed at the end of the outer air guide plate 200 and is coaxially mounted with the rotation axis of the outer air guide plate 200 to collect the rotation angle of the outer air guide plate 200.

[0104] The first acquisition module includes a second angle sensor 310, which monitors the swing position of the inner air guide plate 300 in real time. The output value of the second angle sensor 310 is C4.

[0105] In some embodiments, the second angle sensor 310 is installed at the end of the inner air guide plate 300, and the second angle sensor 310 is coaxially installed with the rotation axis of the inner air guide plate 300 to collect the rotation angle of the inner air guide plate 300.

[0106] The first acquisition module includes a third angle sensor 610, which is used to monitor the swing position of the guide vane 600 in real time. The output value of the third angle sensor 610 is C5.

[0107] In some embodiments, a third angle sensor 610 is installed on the lower part of the air guide blade 600 and is coaxially mounted with the rotation axis of the air guide blade 600 to collect the rotation angle of the air guide blade 600.

[0108] Under different operating conditions, the temperature of the heat exchanger 400, the speed of the heat exchange fan 500, the angle of the outer air guide plate 200, the angle of the inner air guide plate 300, and the rotation angle of the air guide blade 600 of the indoor unit of the air conditioner are not constant. Moreover, the temperature of the heat exchanger 400, the speed of the heat exchange fan 500, the angle of the outer air guide plate 200, the angle of the inner air guide plate 300, and the rotation angle of the air guide blade 600 are independent of each other. Therefore, the output value C1 of the temperature sensor 410, the output value C2 of the speed sensor 510, the output value C3 of the first angle sensor 210, the output value C4 of the second angle sensor 310, and the output value C5 of the third angle sensor 610 can generate a data acquisition sequence (C1-C2-C3-C4-C5).

[0109] Since the temperature of the heat exchanger 400 varies under different operating conditions of the indoor unit of the air conditioner, C1 has N possible values.

[0110] Since the speed of the heat exchange fan 500 varies under different operating conditions of the indoor unit of the air conditioner, C2 has N possible values.

[0111] Since the vertical rotation angle of the outdoor air guide plate 200 changes under different operating conditions of the indoor unit of the air conditioner, C3 has N possible values.

[0112] Since the vertical rotation angle of the inner air guide plate 300 changes under different operating conditions of the indoor unit of the air conditioner, C4 has N possible values.

[0113] Since the left and right rotation angle of the air guide vane 600 changes under different operating conditions of the indoor unit of the air conditioner, C5 has N possible values.

[0114] To ensure the finiteness of the C1 to C5 data, each data point has a certain data scale value, and each data point has only N finite possible values. For example, if the temperature of the heat exchanger 400 is within a certain range, the output value C1 of the temperature sensor 410 is a certain fixed value; if the speed of the heat exchange fan 500 is within a certain range, the output value C2 of the speed sensor 510 is a certain fixed value; if the vertical rotation angle of the outer air guide plate 200 is within a certain range, the output value C3 of the first angle sensor 210 is a certain fixed value; if the vertical rotation angle of the inner air guide plate 300 is within a certain range, the output value C4 of the second angle sensor 310 is a certain fixed value; if the horizontal rotation angle of the air guide blade 600 is within a certain range, the output value C5 of the third angle sensor 610 is a certain fixed value.

[0115] In some embodiments, the temperature range of the heat exchanger 400 collected by the temperature sensor 410 is typically 3°C to 60°C.

[0116] When the temperature range of the heat exchanger 400 collected by the temperature sensor 410 is large, it may lead to a large acquisition error of the temperature sensor 410. In this embodiment, the temperature range of the heat exchanger 400 is further subdivided into multiple ranges to reduce the acquisition error of the temperature sensor 410.

[0117] Specifically, the temperature range of the heat exchanger 400 collected by the temperature sensor 410 is x1℃~x2℃. The temperature range of the heat exchanger is divided into y1 sub-ranges, which are numbered sequentially from 1 to y1. The data resolution value is x3℃. The relationship between x1, x2, x3 and y1 is (x2-x1) / y1=x3.

[0118] When the temperature of heat exchanger 400 is between x1℃ and (x1+x3)℃, the temperature of heat exchanger 400 is in the first sub-interval. For ease of description, the output value of the temperature of heat exchanger 400 in the first sub-interval is denoted as C1=1. At this time, the output value of temperature sensor 410 is the middle value of the first sub-interval, i.e., C1=(x1+x1+x3) / 2.

[0119] When the temperature of heat exchanger 400 is between x1℃ and (x1+2x3)℃, the temperature of heat exchanger 400 is in the second sub-interval, C1=2. At this time, the output value of temperature sensor 410 is the middle value of the second sub-interval, that is, C1=(x1+x1+2x3) / 2.

[0120] When the temperature of heat exchanger 400 is between x1℃ and (x1+3x3)℃, the temperature of heat exchanger 400 is in the third sub-interval, C1=3. At this time, the output value of temperature sensor 410 is the middle value of the third sub-interval, that is, C1=(x1+x1+3x3) / 2.

[0121] Similarly, when the temperature of heat exchanger 400 is between x1℃ and (x1+y1x3)℃, the temperature of heat exchanger 400 is in the y1 sub-interval, C1=y1. At this time, the output value of temperature sensor 410 is the middle value of the y1 sub-interval, that is, C1=(x1+x1+y1x3) / 2.

[0122] It should be noted that the output value C1 of the temperature sensor 410 ranges from 1 to y1.

[0123] To ensure visualization accuracy and keep the amount of data small, y1 is usually set to 10.

[0124] The wind speed range collected by the speed sensor 510 is x1 RPM to x2 RPM. The wind speed range collected by the speed sensor 510 is typically 0-1000 RPM. The value of the speed sensor 510 ranges from 1 to y2, and y2 is typically taken as 10.

[0125] The method for determining the values ​​of the speed sensor 510 and the temperature sensor 410 is the same, and will not be repeated here.

[0126] The vertical rotation angle of the outer air guide plate 200 is x1° to x2°. In practical applications, when the size of the outer air guide plate 200 is large, the vertical rotation angle is usually -60° to 60°. The vertical rotation angle of a common outer air guide plate 200 is usually -40° to 40°. The value of the first angle sensor 210 is 1 to y3, usually y3 = 5 or y3 = 10.

[0127] The method for determining the values ​​of the first angle sensor 210 and the temperature sensor 410 is the same, and will not be repeated here.

[0128] The vertical rotation angle of the inner air guide plate 300 is x3° to x4°, and the vertical rotation angle of the inner air guide plate 300 is usually 0° to 45°. The value of the second angle sensor 310 is 1 to y4, and y4 is usually taken as 5.

[0129] The method for determining the values ​​of the second angle sensor 310 and the temperature sensor 410 is the same, and will not be repeated here.

[0130] The left and right rotation angle of the guide vane 600 is x3° to x4°, and the left and right rotation angle of the guide vane 600 is usually -70° to 70°. The value of the third angle sensor 610 is 1 to y5, and y5 is usually taken as 5.

[0131] The method for determining the values ​​of the third angle sensor 610 and the temperature sensor 410 is the same, and will not be repeated here.

[0132] It should be noted that at this point, the sequence C1-C2-C3-C4-C5 has a total of y1×y2×y3×y4×y5 permutations and combinations.

[0133] In practical applications, the air conditioning outlet air field corresponding to the five permutations of the collected sequence (C1-C2-C3-C4-C5) y1×y2×y3×y4×y5 is usually preprocessed to generate a simulated air field under each combination, which is then stored in the storage module. When needed, the simulated air field corresponding to the operating state of the indoor air conditioning unit can be retrieved.

[0134] Since the operating information of the indoor unit of the air conditioner can be obtained through the controller of the indoor unit, in some other embodiments of this application, there is no need to set up a sensor to detect and obtain the air outlet field information. The first acquisition module is connected to the controller of the indoor unit of the air conditioner to obtain the air outlet field information of the indoor unit of the air conditioner in operation.

[0135] The first acquisition module obtains the airflow field information of the indoor unit of the air conditioner from the controller through communication transmission, eliminating the need to install sensors inside the indoor unit for physical detection, which can reduce costs.

[0136] It should be noted that the communication transmission methods include, but are not limited to, Bluetooth and WiFi.

[0137] It should also be noted that obtaining the operating status of the indoor unit of the air conditioner from the controller is existing technology in this field and will not be elaborated here.

[0138] The air conditioning air field display device includes a storage module that stores simulated air fields. The simulated air fields are constructed based on the air outlet air field information of the indoor unit of the air conditioner under different operating conditions. Multiple simulated air fields are usually set, and at least some of the simulated air fields are set to correspond to the air outlet air field information of the indoor unit of the air conditioner under different operating conditions.

[0139] The air conditioning air field display device includes a simulation module, which is used to construct a simulated air field of the air conditioning indoor unit based on the air field information of the air outlet of the indoor unit during actual operation.

[0140] It should be noted that the simulation module can construct a simulated wind field based on the outflow wind field information using existing technology, which will not be elaborated here.

[0141] Building a simulated wind field based on the outflow wind field information takes a certain amount of time. If the outflow wind field information is obtained on-site in actual applications and then a simulated wind field is built on-site, users will have to wait, which will reduce the user experience.

[0142] By pre-constructing simulated air fields based on the air outlet air fields under different operating states of the air conditioner indoor unit, and storing multiple simulated air fields in the storage module, when it is necessary to display the air outlet effect of the air conditioner indoor unit under different operating states, the simulated air field corresponding to the operating state of the air conditioner indoor unit can be selected from the storage module.

[0143] The air conditioning air field display device includes a display module, which is used to display images so that users can view the air outlet air field of the indoor unit of the air conditioner from the display module, thereby realizing the visualization of the air outlet air field of the indoor unit of the air conditioner.

[0144] The display module is located on the mobile terminal 800. The mobile terminal 800 and the indoor air conditioner unit are set up independently so that the operation of the display module and the operation of the indoor air conditioner unit are independent and do not interfere with each other. Without changing the existing structure of the indoor air conditioner unit or affecting its existing performance, users can view the air outlet effect image of the indoor air conditioner unit on the mobile terminal 800.

[0145] In some embodiments, the mobile terminal 800 is a mobile phone or a tablet computer, and the display module is the display screen of the mobile phone or the display screen of the tablet computer.

[0146] The airflow field of the indoor unit of the air conditioner is a three-dimensional airflow field, and the simulated airflow field is also a three-dimensional airflow field. The simulated airflow field image is a dynamic image. The simulated airflow field appears different from different viewing angles; that is, the simulated airflow field image is also different under different display angles.

[0147] To better demonstrate the airflow effect of the indoor unit of the air conditioner, the simulated airflow image displayed on the display module is not a simulated airflow at a fixed angle. Multiple simulated airflow images can be generated, each corresponding to a different display viewpoint. This allows users to select the desired simulated airflow image and view the airflow effect of the indoor unit from multiple different angles. It should be noted that the display viewpoint of the simulated airflow can also be considered the user's viewing viewpoint.

[0148] To facilitate users' viewing of the air outlet effect of the air conditioner indoor unit, this application allows users to hold the display module or approach the display module to view the air outlet air field information of the air conditioner indoor unit. Therefore, the viewing angle limited between the user and the air conditioner indoor unit can be regarded as the display angle limited between the display module and the air conditioner indoor unit. Since the display module is integrated into the mobile terminal 800, the display angle limited between the display module and the air conditioner indoor unit can also be regarded as the display angle limited between the mobile terminal 800 and the air conditioner indoor unit.

[0149] In this embodiment, the relative positional relationship between the mobile terminal 800 and the indoor unit of the air conditioner is calculated to determine the display viewing angle defined by the mobile terminal 800 and the indoor unit, thereby obtaining the viewing angle required by the user. It should be noted that the user's viewing angle is also the display viewing angle simulating the wind field.

[0150] In the prior art, the mobile terminal 800 is usually equipped with a position calculation module, which is used to calculate the relative positional relationship between the mobile terminal 800 and the indoor unit of the air conditioner in order to determine the viewing angle jointly defined by the mobile terminal 800 and the indoor unit of the air conditioner.

[0151] like Figure 3 As shown, a reference position is set on the outside of the indoor unit of the air conditioner, which is the origin of the indoor unit.

[0152] The air conditioning wind field display device includes a second acquisition module, which is used to acquire a reference position.

[0153] The second acquisition module is located on the mobile terminal 800 so that users can obtain the reference position through the mobile terminal 800.

[0154] In some embodiments, the second acquisition module can be the camera of a mobile phone or tablet computer, which acquires the reference position through the camera.

[0155] It should be noted that the simulation module can be located on the mobile terminal 800 or on the technician's computer. When the simulation module is located on the technician's computer, the simulated wind field constructed by the simulation module is displayed on the mobile terminal 800 via wired or wireless transmission.

[0156] After the second acquisition module obtains the reference position, the position calculation module uses the reference position as the origin of the air conditioner indoor unit to calculate the spatial relative positional relationship between the origin of the mobile terminal 800 and the reference position, so as to determine the display angle formed by the mobile terminal 800 and the air conditioner indoor unit.

[0157] It should be noted that the origin of the mobile terminal 800 is usually pre-set in the location calculation module, which is existing technology in this field and will not be elaborated further.

[0158] The location calculation module includes an accelerometer, which is used to obtain the distance between the mobile terminal 800 and the indoor unit of the air conditioner; the location calculation module also includes a gyroscope, which is used to obtain the angle between the mobile terminal 800 and the indoor unit of the air conditioner.

[0159] The accelerometer and gyroscope can calculate the relative position between the mobile terminal 800 and the indoor unit of the air conditioner based on the reference position, thereby determining the display angle of the mobile terminal 800 and the display angle of the simulated wind field.

[0160] like Figure 5 and Figure 6 As shown, a first coordinate system is established with the reference position as the origin, and the indoor unit of the air conditioner is located in the first coordinate system; a second coordinate system can be established with the center of the mobile terminal 800 as the origin, and the mobile terminal 800 is located in the second coordinate system.

[0161] It should be noted that in the first coordinate system, the Z1 axis is set vertically upwards, the Y1 axis is set horizontally in a direction away from the rear of the indoor unit of the air conditioner, and the X1 axis is set perpendicular to the Y1 axis in the horizontal plane. In the second coordinate system, the Z2, Y2, and X2 axes are set corresponding to the Z1, Y1, and X1 axes.

[0162] The location calculation module can use the reference position as the origin to obtain the distance L1 in the horizontal plane and the distance L2 in the vertical plane between the mobile terminal 800 and the casing 100.

[0163] The position calculation module can use the reference position as the origin to calculate the angle α1 formed by the line connecting the mobile terminal 800 and the housing 100 in the horizontal plane and the X1 axis, and the angle β1 formed by the line connecting the mobile terminal 800 and the housing 100 in the vertical plane and the Y1 axis.

[0164] The position calculation module can calculate the included angle α2 formed between the mobile terminal 800 and the X2 axis in the horizontal plane, and the included angle β2 formed between the mobile terminal 800 and the Z2 axis in the vertical plane.

[0165] The display angle between the mobile terminal 800 and the indoor unit of the air conditioner can be calculated based on L1, L2, α1, α2, β1, and β2.

[0166] Since the second acquisition module can obtain the reference position, the accelerometer and gyroscope can calculate the relative positional relationship between the first coordinate system and the second coordinate system. The specific technical methods used by the accelerometer and gyroscope to calculate the relative positional relationship between the mobile terminal 800 and the indoor unit of the air conditioner are existing technologies in this field and will not be elaborated here.

[0167] like Figure 7 As shown, when the mobile terminal 800 is in the first position (i.e., the display module is in the first position), the mobile terminal 800 and the air conditioner indoor unit form a first viewing angle.

[0168] like Figure 8 As shown, when the mobile terminal 800 is in the second position, the mobile terminal 800 and the indoor unit of the air conditioner form a second viewing angle.

[0169] When the mobile terminal 800 moves from the first position to the second position, the simulated wind field image displayed on the display module also changes because the display viewing angle of the simulated wind field changes.

[0170] Because the simulated wind field is a three-dimensional wind field, the image of the simulated wind field will differ depending on the relative position of the simulated wind field. In short, even from the same viewing angle, the image of the simulated wind field will differ between the location at the geodetic origin of the simulated wind field and a location 10 meters away from the geodetic origin.

[0171] Based on this, in this application, the reference position obtained by the second acquisition module is used as the geodetic origin of the simulated wind field.

[0172] If only the simulated airflow image is displayed on the display module, although users can intuitively see the airflow effect of the air conditioner indoor unit, the simulated airflow image displayed on the display module still cannot effectively demonstrate the airflow effect of the air conditioner indoor unit due to the lack of the air conditioner indoor unit as a reference.

[0173] Based on this, the air conditioning air field display device includes an input module, which is used to acquire an image of the air conditioning indoor unit from the display view.

[0174] By having the input module acquire an image of the indoor unit of the air conditioner from the display view, and then overlaying the image of the indoor unit of the air conditioner with a simulated air field image on the display module, the airflow from the air outlet 102 of the casing to the indoor unit of the air conditioner and the air field after the airflow from the indoor unit of the air conditioner is distributed in the space are simulated, thereby better demonstrating the air outlet effect of the indoor unit of the air conditioner.

[0175] It should be noted that when the viewing angle defined by the display module and the indoor unit changes, the angle of the image of the indoor unit acquired by the input module also changes accordingly. That is, when the mobile terminal 800 is in the first position, the image of the indoor unit acquired by the input module is the image of the indoor unit from the first viewing angle; when the mobile terminal 800 is in the second position, the image of the indoor unit acquired by the input module is the image of the indoor unit from the second viewing angle. When the position of the mobile terminal 800 changes, the input module needs to reacquire the image of the indoor unit.

[0176] In some embodiments, the input module is a camera of a mobile phone or tablet computer, which captures an image of the indoor unit of the air conditioner from a certain display angle.

[0177] The air conditioning air field display device includes a control module, which is connected to the first acquisition module. The control module is configured to control the first acquisition module to acquire the air field information of the air outlet of the indoor unit of the air conditioner under the current operating status.

[0178] When the first acquisition module is a sensor, the control module is configured to: generate outlet air temperature information based on the temperature of the heat exchanger 400 detected by the temperature sensor 410; generate outlet air speed information based on the rotational speed of the heat exchange fan 500 detected by the speed sensor 510; and generate outlet air direction information based on the rotational angle of the outer air guide plate 200 detected by the first angle sensor 210, the rotational angle of the inner air guide plate 300 detected by the second angle sensor 310, and the rotational angle of the air guide blade 600 detected by the third angle sensor 610.

[0179] When the first acquisition module obtains the airflow field information through communication connection with the controller of the indoor unit of the air conditioner, the control module is configured to: control the first acquisition module to obtain the airflow field information of the indoor unit of the air conditioner from the controller.

[0180] The control module is connected to the storage module, and the control module is configured to select the corresponding simulated wind field from the storage module based on the air field information collected by the first acquisition module.

[0181] The control module is connected to the simulation module. The control module is configured to control and construct a simulated air field based on the air field information of the air outlet of the indoor unit during actual operation, and store the simulated air field in the storage module.

[0182] The control module is connected to the display module. The control module is configured to acquire a simulated wind field image from the display viewpoint and display the acquired simulated wind field image on the display module.

[0183] The control module is connected to the second acquisition module, and the control module is configured to control the second acquisition module to input the reference position to be acquired.

[0184] The control module is also configured to control the simulated wind field to simulate the origin of the wind field on the ground at a reference location.

[0185] The control module is connected to the position calculation module. The control module is configured to: control the position calculation module to use the reference position as the origin of the air conditioner indoor unit, calculate the relative position relationship between the display module and the air conditioner indoor unit at the current position, and determine the display viewing angle formed by the display module and the air conditioner indoor unit.

[0186] When the position calculation module includes an accelerometer and a gyroscope, the control module is configured to control the accelerometer and gyroscope to calculate the relative positional relationship between the mobile terminal 800 and the indoor unit of the air conditioner, as well as the display angle of the simulated wind field, based on the reference position.

[0187] The control module is connected to the input module and is configured to: control the input module to input the acquired image of the air conditioner indoor unit; and overlay the acquired image of the air conditioner indoor unit onto the display module.

[0188] It should be noted that, since the airflow effect of the air conditioner indoor unit can be better displayed by superimposing the module's wind field image and the air conditioner indoor unit image obtained by the input module, the control module is further configured to superimpose the acquired simulated wind field image and the air conditioner indoor unit image obtained by the input module and display them on the display module.

[0189] When the indoor unit of the air conditioner is being displayed, its operating status may be switched according to the user's needs. As the operating status changes, the airflow field information also changes accordingly, and the simulated airflow field selected based on this information also needs to be adjusted. It should be noted that during this process, the spatial relative position between the display module and the indoor unit remains unchanged. Therefore, the display perspective of the simulated airflow field remains unchanged, and the input module does not need to re-acquire the image of the indoor unit.

[0190] When the indoor unit of the air conditioner switches from the first operating state to the second operating state, the air field information of the indoor unit changes, that is, the simulated air field changes. However, since the position of the display module does not change, the display view of the simulated air field does not change, and the image of the indoor unit of the air conditioner does not change.

[0191] like Figure 10 As shown, when the indoor unit of the air conditioner switches from the first operating state to the second operating state, the control module is further configured to: update the air outlet field information acquired by the first acquisition module; reselect the simulated air field from the storage module according to the updated air outlet field information acquired by the first acquisition module, and acquire the simulated air field image of the reacquired simulated air field from the display view; and overlay the reacquired simulated air field image with the indoor unit image of the air conditioner input by the input module and display it on the display module.

[0192] When the indoor unit of the air conditioner is running, the user may want to change the viewing angle to observe the airflow effect. When the relative position of the display module and the indoor unit changes, the user's viewing angle and the display angle of the simulated airflow field also change accordingly. It should be noted that at this time, the operating status of the indoor unit does not change, that is, the airflow field information collected by the first acquisition module does not change. Therefore, it is not necessary to reselect the simulated airflow field.

[0193] When the mobile terminal 800 is in the first position, the control module is configured to: control the position calculation module to calculate the relative position relationship between the mobile terminal 800 and the indoor unit of the air conditioner in the first position based on the reference position obtained by the second acquisition module, so as to determine the first viewing angle; and display the simulated wind field image of the simulated wind field in the first viewing angle on the display module.

[0194] When the mobile terminal 800 is in the second position, the control module is configured to: control the position calculation module to calculate the relative position relationship between the mobile terminal 800 and the indoor unit of the air conditioner in the second position based on the reference position obtained by the second acquisition module, so as to determine the second viewing angle; and display the simulated wind field image of the simulated wind field in the second viewing angle on the display module.

[0195] like Figure 11 As shown, when the mobile terminal 800 moves from the first position to the second position, the input module reacquires the image of the air conditioner indoor unit, and the display perspective formed by the mobile terminal 800 and the air conditioner indoor unit changes from the first perspective to the second perspective; the control module is further configured to: acquire a simulated wind field image under the second perspective; control the input module to input the reacquired image of the air conditioner indoor unit; and superimpose the simulated wind field image under the second perspective with the air conditioner indoor unit image re-input by the input module and display it on the display module.

[0196] It should be noted that when the display module moves from the first position to the second position, although the position of the display module changes, the reference position does not change, that is, the geodetic origin of the simulated wind field remains unchanged. Therefore, there is no need to reposition the geodetic origin of the simulated wind field.

[0197] like Figure 9 As shown, the working principle of the air conditioning air field display device is as follows: The control module controls the first acquisition module to acquire the air outlet air field information of the indoor unit of the air conditioner in the current operating state; selects the simulated air field corresponding to the air outlet air field information acquired by the first acquisition module from the simulated air field pre-stored in the storage module; controls the second acquisition module to input the acquired reference position, and uses the reference position acquired by the second acquisition module as the geodetic origin of the selected simulated air field; controls the position calculation module to use the reference position acquired by the second acquisition module as the origin of the indoor unit of the air conditioner, calculates the positional relationship between the mobile terminal 800 and the indoor unit of the air conditioner, and determines the display angle of the simulated air field; controls the input module to input the acquired image of the indoor unit of the air conditioner under the display angle; and superimposes the simulated air field image under the display angle and the image of the indoor unit of the air conditioner input by the input module on the display module.

[0198] like Figure 7 and Figure 8 As shown, when the mobile terminal 800 moves from the first position to the second position, the display view of the simulated wind field changes from the first view to the second view. The input module re-acquires the image of the indoor air conditioner, changing the image of the indoor air conditioner from the first view to the second view. The control module is configured to: control the position calculation module to calculate the positional relationship between the mobile terminal 800 and the indoor air conditioner when in the second position, and determine the second view; control the input module to re-input the acquired image of the indoor air conditioner; acquire the simulated wind field image in the second view; and overlay the simulated wind field image in the second view with the re-input image of the indoor air conditioner on the display module.

[0199] When the operating status of the indoor unit of the air conditioner switches from the first state to the second state, the airflow field information collected by the first acquisition module changes. The control module is configured to: update the airflow field information acquired by the first acquisition module; reselect a simulated airflow field from the storage module based on the updated airflow field information acquired by the first acquisition module, and acquire a simulated airflow field image of the reselected simulated airflow field from the display view; and overlay the reacquired simulated airflow field image with the indoor unit image input by the input module and display it on the display module.

[0200] It should be noted that in some embodiments, the first acquisition module collects the air outlet air field information of the indoor unit of the air conditioner in real time. When the air outlet air field information changes, the control module controls the storage module to select the simulated air field corresponding to the information collected by the first acquisition module in real time, so as to prevent the simulated air field from not changing when the operating status of the indoor unit of the air conditioner changes, and reduce the time difference between the two changes.

[0201] It should also be noted that regardless of changes in the operating status of the indoor air conditioner unit or the location of the mobile terminal 800, the earth origin of the simulated wind field will not change. The earth origin of the simulated wind field is an absolute origin. Therefore, when the operating status of the indoor air conditioner unit or the location of the mobile terminal 800 changes, the earth origin of the simulated wind field does not need to be redefined.

[0202] The following section uses the mobile terminal 800 as an example of a tablet computer to explain in detail the working principle of the air conditioning wind field display device. The tablet computer's camera serves as both the second acquisition module and the input module; the tablet computer's screen is the display module.

[0203] The control module controls the first acquisition module to collect the airflow field information of the air conditioner indoor unit under the current operating state, and selects the simulated wind field corresponding to the airflow field information collected by the first acquisition module from the storage module; the reference position is obtained through the camera of the tablet computer (second acquisition module), and the control module controls the selected simulated wind field to take the reference position as the geodetic origin of the simulated wind field; the control module controls the accelerometer and gyroscope to calculate the positional relationship between the tablet computer and the air conditioner indoor unit, and determine the display angle of the simulated wind field; the camera of the tablet computer (input module) takes a picture of the air conditioner indoor unit at the current position (first position) of the tablet computer; the control module superimposes the image of the air conditioner indoor unit taken by the tablet computer and the simulated wind field image under the display angle on the tablet computer screen.

[0204] When the tablet moves from the first position to the second position, the control module controls the accelerometer and gyroscope to calculate the positional relationship between the tablet and the indoor unit of the air conditioner in the second position, and redetermines the display angle of the simulated wind field; the tablet's camera re-captures the indoor unit of the air conditioner in the second position of the tablet; the control module overlays the image of the indoor unit of the air conditioner captured by the tablet with the image of the simulated wind field under the redetermined display angle and displays it on the tablet's screen.

[0205] When the air conditioner's operating state switches from the first state to the second state, the control module controls the storage module to reselect a simulated wind field from the pre-stored simulated wind field that corresponds to the air outlet wind field information collected by the first acquisition module; the control module overlays the image of the air conditioner's indoor unit taken by the tablet's camera when the tablet is in the first position with the image of the reselected simulated wind field at the display view on the tablet's screen.

[0206] In some embodiments, the image of the indoor unit of the air conditioner is superimposed on the image of the simulated wind field at the display view and displayed on the tablet computer, so that the user can directly view the image of the air outlet effect of the indoor unit of the air conditioner through the tablet computer.

[0207] In some embodiments, the image of the indoor unit of the air conditioner and the simulated wind field image under the display view are superimposed and transmitted to other display devices for display via wired or wireless communication. Other display devices can be televisions, projectors, or users' mobile phones, etc.

[0208] The aforementioned air conditioning air field display device applies AR technology to demonstrate the air outlet effect of the indoor unit. It constructs a simulated air field based on the air outlet air field information of the indoor unit, simulating the air outlet air field during operation. The constructed simulated air field is stored in a storage module, and a first acquisition module collects the air outlet air field information of the indoor unit under its current operating state. The control module then selects the corresponding simulated air field from the storage module based on the air outlet air field information collected by the first acquisition module, and displays the simulated air field image on the display module to visualize the air outlet effect of the indoor unit. An input module acquires an image of the indoor unit from the user's viewing angle, and also acquires an image of the simulated air field from the user's viewing angle.
