Technical Field

[0001] The present application relates to the technical field of air conditioning, and in particular to an air conditioner. Background Art

[0002] Currently, the controller of the air conditioner is generally a handheld remote control or a wall-mounted touch screen. The display of this type of controller is small and difficult to operate for the elderly or people with poor eyesight. It is planned to consider using space projection to enlarge the display.

[0003] However, in the related art, the angle range of display after spatial projection is limited. If the range is exceeded in the horizontal and vertical directions, part of the screen will be missing, which affects the visual effect and is inconvenient to operate based on the projection.

[0004] In view of this, an air conditioner capable of adjusting the projection position of a display is proposed. Summary of the invention

[0017] When X max <X<X km , Y max <Y<Y km The rotation unit controls the spatial projection unit to rotate the first preset coordinate toward the position coordinate direction of the face or the eye. km <X<X kmax , Y km Y<Y kmax The rotation unit controls the spatial projection unit to rotate the second preset coordinate toward the position coordinate direction of the face or the eye.

[0018] In some embodiments, when X>X kmax , Y>Y kmax , it is judged that the detected person has no control action, the rotation unit does not work, and the air conditioning projection unit maintains the initial position unchanged.

[0019] In some embodiments, when X max >X,Y max >Y, it is determined that the detected person is within the convenient operating range, the rotation unit does not work, and the air conditioning projection unit maintains the initial position unchanged.

[0051] In order to make the purpose and implementation method of the present application clearer, the exemplary implementation method of the present application will be clearly and completely described below in conjunction with the drawings in the exemplary embodiments of the present application. Obviously, the described exemplary embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0052] It should be noted that the brief description of terms in this application is only for the convenience of understanding the embodiments described below, and is not intended to limit the embodiments of this application. Unless otherwise specified, these terms should be understood according to their common and usual meanings.

[0053] The terms "first", "second", "third", etc. in the specification and claims of this application and the above drawings are used to distinguish similar or similar objects or entities, and do not necessarily mean to limit a specific order or sequence, unless otherwise noted. It should be understood that the terms used in this way can be interchangeable under appropriate circumstances.

[0054] The terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover but not exclude inclusion, for example, a product or device comprising a list of components is not necessarily limited to all the components expressly listed but may include other components not expressly listed or inherent to such product or device.

[0055] The present embodiment provides an air conditioner that performs a refrigeration and heating cycle of the air conditioner by using a compressor, a condenser, an expansion valve, and an evaporator. The refrigeration cycle and the heating cycle include a compression process, a condensation process, an expansion process, and an evaporation process. The refrigerant absorbs and releases heat to provide cold or heat to the indoor space, thereby achieving temperature regulation of the indoor space.

[0056] The compressor compresses the refrigerant gas to form a high-temperature and high-pressure state and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed high-temperature and high-pressure gaseous refrigerant into liquid refrigerant, and the heat is released to the surrounding environment through the condensation process.

[0057] The liquid refrigerant flowing out of the condenser enters the expansion valve, which expands the high-temperature and high-pressure liquid refrigerant condensed in the condenser into a low-pressure liquid refrigerant. The low-pressure liquid refrigerant flowing out of the expansion valve enters the evaporator. When the liquid refrigerant flows through the evaporator, it absorbs heat and evaporates into a low-temperature and low-pressure refrigerant gas, and returns the low-temperature and low-pressure refrigerant gas to the compressor. The evaporator can achieve a cooling effect by utilizing the latent heat of evaporation of the refrigerant to exchange heat with the material to be cooled. In the entire cycle, the air conditioner can adjust the temperature of the indoor space.

[0058] The outdoor unit of the air conditioner refers to a portion of a refrigeration cycle including a compressor and an outdoor heat exchanger, the indoor unit of the air conditioner includes an indoor heat exchanger, and an expansion valve may be provided in the indoor unit or the outdoor unit.

[0059] The indoor heat exchanger and the outdoor heat exchanger can function as a condenser or an evaporator. When the indoor heat exchanger functions as a condenser, the air conditioner functions as a heater in a heating mode, and when the indoor heat exchanger functions as an evaporator, the air conditioner functions as a cooler in a cooling mode.

[0060] An air conditioner proposed in the embodiment of the present application, referring to Figure 1The air conditioner includes an indoor unit 200, an outdoor unit 100 and a control device 300. The control device 300 is used to send a control signal and make the indoor unit 200 and the outdoor unit 100 respond to achieve different modes of the air conditioner, for example, a cooling mode, a heating mode, a self-cleaning mode, an anti-mildew mode, etc.

[0061] The air conditioner in the present application may be a central air conditioner, a wall-mounted air conditioner, or a cabinet air conditioner, and the control device 300 may be mounted on a wall or independently provided.

[0062] The control device 300 provided in the embodiment of the present application may also have a variety of implementation forms, for example, it may be a television, a smart TV, a laser projection device, a display 45 (monitor), an electronic bulletinboard, an electronic table, etc.

[0063] Reference Figure 2 The control device 300 further includes a controller 41, a spatial projection unit 42, a rotation unit 43 and an image detection unit 44, wherein the spatial projection unit 42 is electrically connected to the controller 41, and the spatial projection unit 42 is used to transmit the image beam to the projection area to display the image at the correction position of the projection area, and the controller 41 controls the spatial projection unit 42 to display content.

[0064] In some embodiments of the present application, the spatial projection unit 42 includes a control circuit, a light valve and a projection lens, wherein the control circuit is connected to the light valve, and the controller 41 is used to respond to instructions, modulate the light beam irradiated to its surface into an image beam according to the light valve control signal control method, and transmit the image beam to the projection lens.

[0065] The rotation unit 43 is connected to the spatial projection unit 42. The rotation unit 43 can be used to realize the rotation of the spatial projection unit 42 structure. The rotation unit 43 is electrically connected to the controller 41. The controller 41 controls the rotation direction and rotation angle of the rotation unit 43, thereby driving the spatial projection unit 42 to rotate to adjust the projection position of the image. The image detection unit 44 is used to collect a face or an image of a face to confirm the sight range of the target reference person, thereby adjusting the rotation unit 43 to change the projection position of the spatial projection unit 42 so that the projection position corresponds to the face or eye of the target reference person.

[0066] The controller 41 is configured to refer to Figure 3When the control device 300 is working (step S1), the space projection unit 42 performs initial projection and forms a fixed visible range 8 in the projection area (step S2). The fixed visible range 8 is defined as an area formed with a preset area and a preset shape with the initial position as the center, and an adjustable visible range 7 with the initial position as the center is formed outside the fixed visible range 8. The image detection unit 44 detects the position of the face or the eye (step S3). Determine the range of the corresponding position coordinates,

[0067] First, determine whether the corresponding position coordinates are within the fixed visible range 8 (step S4). When it is determined in step S4 that the position coordinates are not within the fixed visible range 8, execute step S5; determine whether the corresponding position coordinates are within the adjustable visible range 7; when it is determined in step S4 that the position coordinates are within the fixed visible range 8, continue to execute step S3.

[0068] When it is determined in step S5 that the corresponding position coordinates are not within the adjustment visible range 7, step S3 is executed.

[0069] When it is determined in step S5 that the corresponding position coordinates are within the adjusted visible range 7, step S6 is executed, and the rotation unit 43 controls the spatial projection unit 42 to rotate in the direction of the detected position coordinates, and the spatial projection unit 42 projects at the corrected position so that the position coordinates of the face or the eye are within the fixed visible range 8.

[0070] It should be noted that the projection area in the present application can be a projection screen, a wall that can be projected, or an open space to meet the projection requirements of the space projection unit 42.

[0071] Through the above settings, the rotation unit 43 can be controlled to drive the spatial projection unit 42 to rotate according to the position coordinates of the face or eyes of the target reference person to change the projection position of the spatial projection unit 42, so that the user can rotate within a certain range to achieve normal acquisition of the projection content and ensure the integrity of the projection content. This application dynamically adjusts the display area of ​​the spatial projection unit in a small range through head position recognition such as face and eyes to adapt to different viewing angles, greatly improving the user experience.

[0072] It should be noted that the image detection unit 44 continuously collects the position of the user to timely adjust the position change of the space projection unit and change the projection position in time.

[0073] It should be noted that the air conditioner projection unit can project the display content of the display, or the control buttons of the control device. When the control buttons are projected, the control device can be operated in combination with the following spatial touch technology.

[0074] In some embodiments of the present application, the image detection unit 44 is configured as a camera, which is facing the user end. The camera can accurately capture the movements and positions of the user's fingers, and determine the touch commands triggered by the user in combination with the displayed content; the camera can accurately capture the user's position, and control the projection position of the spatial touch unit accordingly, thereby achieving the effect of shadow following the person.

[0075] The display content may be data of display content of the display 45 or data of projection content of the space projection unit 42 .

[0076] The spatial projection unit 42 in the present application adopts the principle of spatial projection imaging, and through optical (reflection, refraction, etc.) design, the display content of the display 45 can be imaged in space (air). The imaging effect is shown in FIG. Figure 4 , using spatial projection imaging technology, the display content of the air conditioner control device 300 is spatially projected, which can effectively solve the problem that the user is not able to directly see the display content due to other reasons such as vision or angle.

[0077] The controller 41 controls the operation of the air conditioner and responds to the user's operation through various software control programs stored in the memory. The controller 41 controls the overall operation of the indoor unit 200 and the outdoor unit 100. For example, in response to receiving a user command to select a UI object to be displayed at the projection position, the controller 41 can perform an operation related to the object selected by the user command.

[0078] In some embodiments of the present application, the controller 41 includes at least one of a central controller 41 (Central Processing Unit, CPU), a video processor, an audio processor, a graphics processor (Graphics Processing Unit, GPU), RAM (Random Access Memory, RAM), ROM (Read-Only Memory, ROM), a first interface to an nth interface for input / output, a communication bus (Bus), etc.

[0079] In some embodiments of the present application, the projected image can be projected in equal proportion or at a set magnification ratio of the display content of the control device 300 to meet the needs of different scenes and different groups of people. When the image is projected in equal proportion, the requirements for the projection area will be reduced, which is conducive to improving the application scenarios of the air-conditioning projection unit; when the image is projected at a set magnification ratio, the problem that the font or symbol of the displayed content is too small and the user cannot directly judge it can be solved.

[0080] In some embodiments of the present application, reference Figure 5The adjustable visual range 7 is defined as a first adjustable area 71 close to the fixed visual range 8 and a second adjustable area 72 far from the fixed visual range 8. The edge coordinates of the first adjustable area 71 are defined as (X km , Y km ), the edge coordinates of the second adjustable area 72 are defined as (X kmax , Y kmax ), the edge coordinates of the fixed visual range 8 are defined as (X gmax , Y gmax ), the position coordinates of the face or eyes are defined as (X, Y).

[0081] It should be noted that the fixed visual range 8 and the adjustable visual range 7 may vary depending on the performance and settings of the spatial projection unit 42. The above is only for the convenience of explanation, and only the technical solution for adjusting the projection position is described here.

[0082] In the present application, the values ​​of the fixed visible range 8 and the adjustable visible range 7 can be obtained by pre-setting or by feedback of the projection position when the spatial projection unit 42 is used for initial projection.

[0083] Reference Figure 6 , the image detection unit 44 faces the user end, the image detection unit 44 obtains the position coordinates of the face or the eye (step S3), and sends the image detection unit 44 to the controller 41. The controller 41 compares the position coordinates with the fixed visible range 8 and the adjustable visible range 7, determines the range of the position coordinates, and thereby obtains the running direction of the spatial projection unit 42, and drives the rotation unit 43 to perform corresponding actions.

[0084] Determine whether the position coordinates are located in the fixed visible area 8 (step S401). When the position coordinates are located in the fixed visible area 8, execute step S602, the rotation unit 43 does not work, and the air-conditioning projection unit 42 maintains the initial position unchanged; when the position coordinates are located in the fixed visible area 8, execute step S402 to determine whether the position coordinates are located in the first adjustable area 71.

[0085] When it is determined in step S402 that the position coordinates are located in the first adjustable area 71, step S603 is executed, and the rotation unit 43 controls the spatial projection unit 42 to rotate a certain angle toward the position coordinates of the face or the eye; when it is determined in step S402 that the position coordinates are not located in the first adjustable area 71, step S403 is executed to determine whether the position coordinates are located in the second adjustable area 72.

[0086] When it is determined in step S403 that the position coordinates are located in the second adjustable area 72, step S601 is executed, and the rotation unit 43 controls the spatial projection unit 42 to rotate a certain angle toward the position coordinates of the face or the eye; when it is determined in step S403 that the position coordinates are not located in the second adjustable area 72, step S604 is executed, the rotation unit does not work, and the air conditioning projection unit 42 maintains the initial position unchanged.

[0087] Specifically, when X gmax <X<X km , Y gmax <Y<Y km The rotation unit 43 controls the spatial projection unit 42 to rotate the first preset coordinate toward the position coordinate direction of the face or the eye. For example, the first preset coordinate is (X km , Y km ), when X km <X<X kmax , Y km Y<Y kmax The rotation unit 43 controls the spatial projection unit 42 to rotate the second preset coordinate toward the position coordinate direction of the face or the eye. For example, the second preset coordinate is (X kmax , Y kmax ).

[0088] It should be noted that the rotational position of the position coordinates within different ranges can be adjusted as needed.

[0089] In some embodiments of the present application, when the target reference person is not in the control area or the position of the face or eyes is not within the control area, the rotation unit 43 does not operate, and the projection position of the spatial projection unit 42 does not change. kmax , Y>Y kmax , it is determined that the detected person has no control action, the rotating unit 43 does not work, and the air conditioning projection unit maintains the initial position unchanged.

[0090] In some embodiments of the present application, when the target reference person is within the control area or the position of the face or eyes is within the control area, the projection position of the spatial projection unit 42 does not need to be adjusted, and the rotation unit 43 does not operate. gmax >X,Y gmax >Y, it is determined that the detected person is within the convenient operating range, the rotating unit 43 does not work, and the air conditioning projection unit maintains the initial position unchanged.

[0091] Currently, some air conditioners use capacitive screens, which achieve contactless spatial touch by adjusting the screen sensitivity. However, the effective touch distance of this method is relatively small. Adjusting a larger distance requires sacrificing the sensitivity of the capacitive screen touch, which can easily cause misoperation and prevent the user's control commands from being output correctly, reducing the user experience. Therefore, contactless spatial control is required without reducing the performance of the display screen.

[0092] In summary, in order to further perform contactless space control, in some embodiments of the present application, refer to Figure 7 The control device 300 also includes a display 45 and a spatial touch processing unit 46. The display 45 is used to display the interactive information of the air conditioner. The spatial touch processing unit 46 is connected to the display 45 and the image detection unit 44. The image detection unit 44 is set on the display 45, and the image detection unit 44 is facing the user end to facilitate the collection of image data of the user. The spatial touch processing unit 46 is configured so that when the user uses spatial touch to control the air conditioner, the image detection unit 44 collects the operation area and operation height of the user's finger, combines the current display content of the display 45, determines the user-triggered command, and sends it to the controller 41, so that the indoor unit 200 and / or the outdoor unit 100 respond.

[0093] Specifically, in addition to capturing images of the user's face or eyes, the image detection unit 44 can also capture the position of the finger being used. When the image detection unit 44 captures the position of the user's finger, the area where the finger is currently located and the height of the finger can be obtained. Combined with the display content of the current display 45, the operation function area where the finger is currently located is mapped, and the height of the finger is compared with the preset trigger height to determine whether the function button of the corresponding operation function area is triggered. Based on the control instructions issued by the user obtained as above, and through the control of the controller 41, the indoor unit 200 and the outdoor unit 100 make corresponding responses.

[0094] Through the above settings, the image detection unit 44 can obtain the position of the finger, and obtain the user's trigger function accordingly, thereby realizing contactless control of the air conditioner.

[0095] In this embodiment, the display and button content of the traditional controller 41 are utilized, and a spatial touch module 5 is added on the basis of maintaining the button position, icon, function, etc. of the control device 300. Through a simple design, the display and buttons of the controller 41 are combined with the spatial touch to achieve contactless touch.

[0096] The display 45 includes a display screen component for presenting images and a driving component for driving image display, and is used to receive image signals output from the controller 41, and display video content, image content, and menu control interface components and user control UI interface.

[0097] The display 45 may be a liquid crystal display 45 , an OLED display 45 , or a projection display 45 . The display 45 is connected to the spatial projection unit 42 , and the spatial projection unit 42 projects the display screen of the display 45 .

[0098] The user may input a user command through a graphical user interface (GUI) displayed on the display 45, and the user input interface receives the user input command through the graphical user interface (GUI). Alternatively, the user may input a user command through a specific sound or gesture, and the user input interface receives the user input command by recognizing the sound or gesture through a sensor.

[0099] In some embodiments of the present application, reference Figure 8 The rotation unit 43 is also connected to the spatial touch module 5. The rotation unit 43 can also be used to realize the rotation of the structure of the spatial touch module 5. The rotation unit 43 is electrically connected to the controller 41. The controller 41 controls the rotation direction and rotation angle of the rotation unit 43, thereby adjusting the position and angle of the structure of the spatial touch module 5. Specifically, the rotation unit 43 controls the spatial touch module 5 and the spatial projection unit 42 to rotate within a preset horizontal angle and a preset vertical angle.

[0100] In some embodiments of the present application, the user can operate the control device 300 without contact. The user can trigger by hovering on the display 45, and use the image detection unit 44 to obtain the operating function area where the finger is located according to the content displayed on the display 45. At the same time, the infrared detection unit 47 is used to determine whether to trigger the corresponding function button, thereby realizing the input of user control commands and inputting them into the controller 41 through the user input interface.

[0101] "User interface" is a medium interface for interaction and information exchange between an application or operating system and a user, which realizes the conversion between the internal form of information and the form acceptable to the user. The commonly used form of user interface is the Graphical User Interface (GUI), which refers to a user interface related to computer operation displayed in a graphical manner. It can be an interface element such as an icon, window, control, etc. displayed on the display 45 of an electronic device, where the control can include icons, buttons, menus, tabs, text boxes, dialog boxes, status bars, navigation bars, widgets, etc.

[0102] Since the instruction is determined only by the image detection unit 44, the structure is simple, but inaccuracies are inevitable. In order to improve the accuracy of user instruction acquisition. In some embodiments of the present application, referring to FIG. 9, the control device 300 may also include an infrared detection unit 47, which is connected to the spatial touch processing unit 46. The infrared detection unit 47 is arranged on one side of the display 45, and can detect the distance between the user's finger and the display 45, and thereby determine whether the function button of the corresponding operation function area is triggered. The spatial touch processing unit 46 is configured to, when the user uses spatial touch to control the air conditioner, the area where the finger is located captured by the image detection unit 44, the spatial touch processing unit 46 determines the operation function area where the finger is located, and determines whether the infrared detection unit 47 detects the finger. When the infrared detection unit 47 detects the finger, the spatial touch processing unit 46 sends the corresponding control instruction to the controller 41, and the controller 41 triggers the corresponding control instruction and controls the indoor unit 200 and the outdoor unit 100 to respond.

[0103] Reference Fig. 9 , the infrared detection unit 47 is electrically connected to the spatial touch processing unit 46, the image detection unit 44 is electrically connected to the spatial touch processing unit 46, and the spatial touch processing unit 46 is electrically connected to the controller 41. In some scenarios, the infrared detection unit 47 may not be used, and a camera may be used to check the touch distance, but the detection accuracy is not high.

[0104] In some embodiments of the present application, when the installation distance between the infrared detection unit 47 and the display 45 is H, when the distance between the finger and the display 45 is not greater than H, the infrared detection unit 47 can detect the effective touch operation of the finger, and combine the touch position of the finger obtained by the image detection unit 44 to obtain the corresponding control instruction triggered by the finger.

[0105] Through the above arrangement, when the user touches the control device 300, there is no need to touch the buttons on the display panel of the display 45 with a finger. When the user is at a certain height from the button position, the infrared detection unit 47 or the image detection unit 44 can determine which button to touch and issue a corresponding control instruction. In the above solution, the touch control using the infrared detection unit 47 is more accurate than that using the image detection unit 44.

[0106] In some embodiments of the present application, reference Fig.10 The image detection unit 44, the spatial touch processing unit 46 and the infrared detection unit 47 together constitute the spatial touch module 5, which is used to realize the spatial touch control of the control device 300 by the user, and realize contactless control. Fig.11 The spatial touch module 5 is installed on the surface of the control device 300 and is higher than the display surface and touch plane of the control device 300 .

[0107] Reference Fig.12 In the embodiment of the present application, the infrared detection unit 47 is exemplarily set as an infrared detection sensor, which uses the infrared detection sensor to determine whether the finger enters the touch range, and determines the effective touch distance by the position of the infrared detection sensor and the display screen assembly. Figure 5 As shown in the judgment diagram of the mid-infrared detection sensor, two infrared detection sensors are used, which are defined as the first infrared detection sensor 471 and the second infrared detection sensor 472, respectively. The first infrared detection sensor 471 is arranged below the second infrared detection sensor 472, and the distance between the upper edge of the detection area of ​​the first infrared detection sensor 471 and the upper surface of the display screen assembly is h1, and the distance between the upper edge of the detection area of ​​the second infrared detection sensor 472 and the upper edge of the detection area of ​​the first infrared sensor is h2. When the first infrared detection sensor 471 is used, touch control can be achieved when the distance between the finger and the upper surface of the display screen assembly is not greater than h1; when the second infrared detection sensor 472 is used, touch control can be achieved when the distance between the finger and the upper surface of the display screen assembly is not greater than h1+h2.

[0108] In this application, the touch position is determined by a camera, and the touch distance is determined by an infrared detection sensor. The combination of the two can realize spatial touch.

[0109] In some embodiments of the present application, the air conditioner may include only the spatial touch module 5, but not the spatial projection unit 42 and the rotation unit 43, and perform spatial touch control on the control device 300 to achieve contactless control of the air conditioner.

[0110] In the present application, the spatial touch processing unit 46 is electrically connected to the image detection unit 44 and the infrared detection unit 47. The spatial touch processing unit 46 receives instructions from the infrared detection unit 47 and the image detection unit 44 and performs control responses. The spatial touch processing unit 46 is physically connected to the spatial projection unit 42, and the relative positions of the two are fixed.

[0111] In some embodiments of the present application, when the image captured by the image detection unit 44 involves multiple faces or eyes, the face or eye closest to the initial position is selected as the target object to adjust the projection position.

[0112] according to Fig.13 The flowchart of FIG. 1 illustrates the adjustment of the spatial projection position.

[0113] Reference Figure 5According to the fixed visible area projected by the spatial projection unit 42, the visible angle range coordinates are established with the projection center as the coordinate origin. The projection center is defined as the initial position (0, 0). When the spatial projection unit 42 is located at the initial fixed position, its projection visible range is the fixed visible range 8. The coordinate points in this area are defined as (X g , Y g ), the edge coordinates of the fixed visual range 8 are defined as (X gmax , Y gmax ).

[0114] When the spatial projection is rotated and at the extreme position of rotation, its projection visible range is the adjustment visible range 7, and the coordinate points within this range are defined as (X k , Y k ), the edge coordinates of the adjustment visual range 7 are defined as (X kmax , Y kmax ), wherein the adjustable visual range 7 can be divided into a first adjustable area 71 and a second adjustable area 72, and the edge coordinates of the first adjustable area 71 are defined as (X km , Y km ), the edge coordinates of the second adjustable area 72 are defined as (X kmax , Y kmax ). The edge coordinates of the first adjustable area 71 are located in the middle of the edge coordinates of the fixed visual range 8 and the edge coordinates of the second adjustable area 72.

[0115] When the control device 300 is working (step S1), the spatial projection unit 42 performs initial projection and forms a fixed visible range 8 in the projection area (step S2). The fixed visible range 8 is defined as an area formed with a preset area and a preset shape centered on the initial position, and an adjustable visible range 7 centered on the initial position is formed outside the fixed visible range 8.

[0116] Select the target reference object, the image detection unit 44 collects the picture of the user end (step S301), and obtains the reference object therein, and determines whether there is a single person in the acquired image (step S302). When it is determined to be a single person, step S303 is executed, and the person is taken as the target reference object to obtain the position coordinates of the face or eyes of the target reference object; when it is determined not to be a single person, step S304 is executed, and the person closest to the initial position (0, 0) is taken as the target reference object to obtain the position coordinates of the face or eyes of the target reference object. Determine the range of the corresponding position coordinates.

[0117] Determine whether the position coordinates are located in the fixed visible area 8 (step S401). When the position coordinates are located in the fixed visible area 8, execute step S602, the rotation unit 43 does not work, and the air-conditioning projection unit 42 maintains the initial position unchanged; when the position coordinates are located in the fixed visible area 8, execute step S402 to determine whether the position coordinates are located in the first adjustable area 71.

[0118] When it is determined in step S402 that the position coordinates are located in the first adjustable area 71, step S603 is executed, and the rotation unit 43 controls the spatial projection unit 42 to rotate a certain angle toward the position coordinates of the face or the eye; when it is determined in step S402 that the position coordinates are not located in the first adjustable area 71, step S403 is executed to determine whether the position coordinates are located in the second adjustable area 72.

[0119] When it is determined in step S403 that the position coordinates are located in the second adjustable area 72, step S601 is executed, and the rotation unit 43 controls the spatial projection unit 42 to rotate a certain angle toward the position coordinates of the face or the eye; when it is determined in step S403 that the position coordinates are not located in the second adjustable area 72, step S604 is executed, the rotation unit does not work, and the air conditioning projection unit 42 maintains the initial position unchanged.

[0120] Specifically, the image detection unit 44 captures the eyes or face of the target reference object and obtains the corresponding position coordinates (X, Y).

[0121] To determine the relative position relationship between the position coordinates and the image detection unit 44 (i.e., the spatial projection unit 42), or to determine the relative position relationship between the position coordinates and the projection area of ​​the spatial projection unit 42, the controller 41 controls the rotation unit 43 according to the face and / or eye coordinates (X, Y), and controls the spatial projection unit 42 to rotate so that the user can better see the projection content.

[0122] Specifically, when the image detection unit 44 captures a human face and / or human eyes within the fixed visual range 8 (ie, X gmax >X,Y gmax >Y), the rotation unit 43 does not work, and the spatial projection unit 42 keeps the origin position unchanged.

[0123] When the image detection unit 44 captures a human face and / or human eyes outside the fixed visual range 8 and within the first adjustable area 71 (i.e., X gmax <X<X km , Y gmax <Y<Y km ), the rotation unit 43 controls the spatial projection unit 42 to rotate toward the face and / or the eyes, and the rotation coordinate is (X km , Y km ).

[0124] When the image detection unit 44 captures a human face and / or human eyes outside the first adjustable area 71 and within the second adjustable area 72 (ie, X km <X<X kmax , Y km Y<Y kmax The rotation unit 43 controls the spatial projection unit 42 to rotate toward the face and / or the eyes, and the rotation coordinate is (X kmax , Y kmax ).

[0125] When the image detection unit 44 captures a human face and / or human eyes outside the adjustable visual range 7 (ie, X>X kmax , Y>Y kmax ), the rotation unit 43 does not work, and the spatial projection unit 42 keeps the origin position unchanged. At this time, it is considered that the person is far away from the controller 41 and there is no control action.

[0126] In some embodiments of the present application, reference Fig.14 The air conditioner also includes a human sensing sensor 48, which is electrically connected to the controller 41. The human sensing sensor 48 is used to detect whether there is a person approaching the air conditioner. When a person approaches, the human sensing sensor 48 outputs an electrical signal to the controller 41. The controller 41 performs projection display and position detection of the face or eyes, and determines whether the projection position needs to be adjusted.

[0127] Through the above-mentioned settings, the controller 41 is awakened according to the electrical signal sent by the human sensing sensor 48. After being awakened, the controller 41 performs projection display and detects the position of the face or eyes, and determines whether the projection position needs to be adjusted. It can effectively detect whether someone is approaching and turn on in advance to facilitate manual start-up by the user, thereby reducing the user's contact in turning on the air conditioner.

[0128] Exemplarily, the human sensing sensor 48 can be set as a human proximity sensor, a laser or infrared detection sensor, and wakes up the controller 41 by detecting the distance of a person approaching the control. After being woken up, the controller 41 performs projection display and face and / or eye detection.

[0129] Among them, the human proximity sensor, also known as the contactless proximity sensor, can use the human proximity sensor YTMW8631 and the human activity monitor YT-EWS to detect the controller 41 of the human approach, which can accurately detect the approach of nearby people and is the best choice for state detection. At the same time, the human proximity sensor has a high detection sensitivity to the movement of nearby people, and suppresses the sound signals of the surrounding environment, and has a strong anti-interference ability.

[0130] In some embodiments of the present application, the control device 300 further includes a communication unit 6, which is a component for communicating with an external device or server according to various communication protocol types. For example, the communication unit 6 may include at least one of a Wifi module, a Bluetooth module, a wired Ethernet module, and other network communication protocol chips or near field communication protocol chips, and an infrared receiver. The control device 300 can establish the transmission and reception of control signals and data signals with an external control device 300 or a server through the communication unit 6.

[0131] An embodiment of the present application proposes an air conditioner, which includes an indoor unit 200, an outdoor unit 100 and a control device 300. The control device 300 is used to send a control signal and make the indoor unit 200 and the outdoor unit 100 respond accordingly. The control device 300 further includes a controller 41, a space projection unit 42 electrically connected to the controller 41, a rotation unit 43 and an image detection unit 44. The rotation unit 43 is controlled by the user's position information collected by the image detection unit 44, so as to control the projection position of the space projection unit 42, so that the projection position of the space projection unit 42 moves with the user's position, thereby improving the user experience.

[0132] To summarize, the embodiment of the present application also proposes a corresponding method for configuring the controller 41. The controller 41 is configured such that, when the control device 300 is working, the spatial projection unit 42 performs initial projection and forms a fixed visible range 8 and an adjustable visible range 7 outside the fixed visible range 8 on the projection area. The image detection unit 44 detects the position of the face or the eye and determines the range of the corresponding position coordinates. When the position coordinates are not within the fixed visible range 8 and are within the adjustable visible range 7, the rotation unit 43 controls the spatial projection unit 42 to rotate in the direction of the detected position coordinates so that the position coordinates of the face or the eye are within the fixed visible range 8. By setting the relationship between the fixed visible range 8 and the adjustable visible range 7 and the position coordinates of the detected face or eyes, the spatial projection unit 42 is driven to rotate in the corresponding direction through the rotation unit 43 to change the actual projection position of the spatial projection unit 42, so that the fixed visible range 8 of the actual projection position corresponds to the position coordinates of the face or eyes, so that the spatial projection unit 42 can display the entire content of the display 45, and the projection position follows the change of the position of the face or eyes, thereby improving the user experience and accuracy of use.

[0133] At the same time, the embodiment of the present application also proposes a spatial touch module 5, which includes an image detection unit 44, an infrared detection unit 47, and a spatial touch processing unit 46. The infrared detection unit 47 is used to detect the touch distance of the finger, and the image detection unit 44 is used to detect the touch area of ​​the finger, and finally the user's touch command is obtained to realize spatial touch. Thus, an air conditioner including a control device 300 that can realize spatial projection display and spatial touch is provided.
