[0029] In order to make the above-mentioned purposes, features and beneficial effects of the embodiments of the present invention more obvious and understandable, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0030] Reference Figure 1, a flow chart of a method for controlling a display screen in an embodiment of the present invention is given. The method for controlling a display screen provided in an embodiment of the present invention can control the opening angle of a display screen on a household appliance. The method for controlling a display screen can specifically include the following steps:

[0031] Step 11, when the display screen opening operation is detected, the user's height detection information is obtained.

[0032] In a specific implementation, the triggering conditions for the display screen opening operation may include multiple conditions. For example, when it is detected that a household appliance is turned on, the display screen opening operation is triggered. For another example, when it is detected that a setting button of a household appliance is triggered, the display screen opening operation is triggered.

[0033] Taking a drum washing machine as an example, when the drum cover of the drum washing machine is detected to be opened, the display screen opening operation is triggered. Or when the user operates the set adjustment button or adjustment knob, the display screen opening operation is triggered. It is understandable that the triggering conditions for the display screen opening operation are different depending on the type of household appliance, and can be specifically set according to the type of household appliance, working mode, and actual application scenario requirements.

[0034] When the display screen opening operation is detected, the height detection information of the user can be obtained. In the embodiment of the present invention, the height detection information of the user can be obtained in the following manner.

[0035] Several infrared emitters are arranged at intervals in the longitudinal direction of the household appliance, and the infrared emitters may be infrared light emitting diodes (LEDs) or other devices capable of emitting infrared light. Several infrared detectors may be distributed at intervals on the operation panel of the household appliance, or on the housing of the household appliance, or on other parts of the household appliance, as long as the height range of the user that can be detected by the several infrared emitters covers the set height range.

[0036] In the embodiment of the present invention, the height range is set to 0.8m to 2m. In actual applications, the height range may be set to other values ​​according to user needs and actual application scenario requirements, which will not be repeated here.

[0037] In an embodiment of the present invention, the light emitted by the selected infrared emitter can be a beam, and the angle range of the light emitted by the infrared emitter is smaller than the preset angle range, so that the area that the infrared emitter can detect is a small area range, thereby ensuring the accuracy of the detected user height range.

[0038] The interval distance and number of the set infrared transmitters can be set according to factors such as the arrangement position of the infrared transmitters, the set position of the infrared transmitters, the set height range, the type of each infrared transmitter, and the region.

[0039] Reference Figure 2 , a schematic diagram of the structure of a household appliance in an embodiment of the present invention is given. Figure 3 A schematic diagram of the arrangement of an infrared transmitter in an embodiment of the present invention is given. Figure 2 Taking the household appliance 100 as a drum washing machine as an example, the drum washing machine has a control panel 20, a display screen 30, three infrared transmitters and an infrared receiver 60, wherein the three infrared transmitters are respectively infrared transmitter 51, infrared transmitter 52 and infrared transmitter 53 from bottom to top in the longitudinal direction. The infrared transmitter 51, infrared transmitter 52 and infrared transmitter 53 are evenly spaced and arranged on the control panel 20.

[0040] Control a number of infrared transmitters to turn on in sequence from bottom to top in the vertical direction according to the set opening conditions, and obtain the user's height detection information based on the time when the reflected light is received by the infrared receiver.

[0041] Usually, when a user operates a household appliance, he or she needs to be within the preset range of the household appliance to be able to touch the display screen or the household appliance. Therefore, the distance between the user and the household appliance can be determined based on the time of the reflected light received by the infrared receiver. When the time of the reflected light received by the infrared receiver is within the preset time threshold, it is determined that the user is detected within the preset range. Conversely, when the time of the reflected light received by the infrared receiver is greater than the preset time threshold, it is determined that the user is not detected within the preset range. The user's height detection information is obtained based on the installation position, angle, height, etc. of the infrared transmitter, and the height detection information is used to indicate whether the infrared transmitter detects the user.

[0042] Step 12: Determine the height range of the user based on the height detection information of the user.

[0043] In a specific implementation, after obtaining the height detection information of the user, the height range of the user may be determined based on the obtained height detection information.

[0044] In the embodiment of the present invention, the height range of the user may be determined in the following manner.

[0045] Each infrared transmitter can detect a different height range. In the vertical direction, from bottom to top, the height range that the infrared transmitter can detect increases successively. To determine the height range of the user, the infrared transmitters are turned on successively in the vertical direction. When the lowest infrared transmitter is turned on, the infrared receiver receives the reflected light of the lowest infrared transmitter for a determination of whether the lowest infrared transmitter has detected the user. When the infrared receiver receives the reflected light of the lowest infrared transmitter for a time period not greater than the preset time threshold, it is determined that the user has been detected. Otherwise, when the infrared receiver receives the reflected light of the lowest infrared transmitter for a time period greater than the preset time threshold, it is determined that the user has not been detected.

[0046] When the bottom infrared transmitter detects the user, it can be confirmed that the user's height is not less than the height range corresponding to the bottom infrared transmitter. In order to accurately confirm the user's height range, turn on the other infrared transmitters above the bottom infrared transmitter in sequence until the previous infrared transmitter among the adjacent infrared transmitters detects the user, but the next infrared transmitter does not detect the user, then the height range corresponding to the previous infrared transmitter is used as the user's height range. The previous infrared transmitter is located below the next infrared transmitter, and when the next infrared transmitter is turned on, the previous infrared transmitter is turned off.

[0047] For example, refer to Figure 4 , a schematic diagram of the control principle of a display screen in an embodiment of the present invention is given. An infrared transmitter and an infrared receiver 60 are arranged on the control panel 20 of the household appliance, and the infrared transmitter 51, the infrared transmitter 52 and the infrared transmitter 53 are arranged from bottom to top in the vertical direction.

[0048] When user D stands in front of the household appliance, the infrared transmitter 51 is turned on, and according to the reflected light corresponding to the infrared transmitter 51 received by the infrared receiver 60, it is determined that the infrared transmitter 51 detects the user D, and the infrared transmitter 52 is turned on, and the infrared transmitter 51 is turned off. When the reflected light corresponding to the infrared transmitter 52 received by the infrared receiver 60 determines that the infrared transmitter 52 does not detect the user D, it is determined that the height range of the user D is within the height range corresponding to the infrared transmitter 51, and the height range corresponding to the infrared transmitter 51 is used as the height range of the user D.

[0049] When user E stands in front of the household appliance, the infrared transmitter 51 is turned on, and according to the reflected light corresponding to the infrared transmitter 51 received by the infrared receiver 60, it is determined that the infrared transmitter 51 detects the user E, and the infrared transmitter 52 is turned on, and the infrared transmitter 51 is turned off. When the reflected light corresponding to the infrared transmitter 52 received by the infrared receiver 60 determines that the infrared transmitter 52 detects the user E, the infrared transmitter 53 is turned on, and the infrared transmitter 52 is turned off. When the reflected light corresponding to the infrared transmitter 53 received by the infrared receiver 60 determines that the infrared transmitter 53 does not detect the user E, it is determined that the height range of the user E is within the height range corresponding to the infrared transmitter 52, and the height range corresponding to the infrared transmitter 52 is used as the height range of the user E.

[0050] In actual applications, there may be a user whose height exceeds the height range that can be detected by the top infrared transmitter. In this case, when the top infrared transmitter detects the user, the height range corresponding to the top infrared transmitter can be used as the user's height range. For example, if the height range corresponding to the top infrared transmitter is 190cm to 200cm, then the user's height range is determined to be 190cm to 200cm.

[0051] Continuing with reference to 4, when user F stands in front of the household appliance, infrared transmitter 51, infrared transmitter 52 and infrared detector 53 detect the user. Since infrared detector 53 is the topmost infrared detector, the height range corresponding to infrared detector 53 is used as the height range of user F, so that the confirmed height range of user F is closer to the actual height of user F.

[0052] Step 13: Determine a target opening angle of the display screen according to the height range of the user.

[0053] In a specific implementation, when users of different heights face the display screen of the same household appliance, the display screen opens at different angles when the user stands normally and faces the display screen. The display screen opening angles corresponding to the height ranges of different users may be pre-stored. The target opening angle of the display screen is determined based on the determined height range of the user.

[0054] Continue to refer to Figure 4, which is a schematic diagram illustrating different target opening angles of the display screen corresponding to users of different heights. When the display screen 30 is in the initial position, the display screen 30 is close to the control panel 20, and can have the same inclination angle as the control panel 20, and the display screen 30 can rotate relative to the control panel 20 around the top. For example, the target opening angle corresponding to a user with a height of H1 is α. For another example, the target opening angle corresponding to a user with a height of H2 is α+β. For another example, the target opening angle corresponding to a user with a height of H3 is α+β+γ. The target opening angle refers to the angle between the position of the display screen 30 after it is opened according to the target opening angle and the initial position.

[0055] Step 14: Control the display screen to open according to the target opening angle.

[0056] In a specific implementation, the display screen can be driven to open according to the target opening angle by a driving mechanism. The driving mechanism can be a motor and a gear matched with the motor. The output speed of the motor can be reduced by the gear, so that the display screen can be controlled to open according to the target opening angle at a suitable speed. It is understandable that the display screen can also be driven to open by other driving mechanisms, which can be selected according to actual application requirements.

[0057] When the display screen is opened according to the target opening angle, when the user views the display screen, the user's line of sight forms a preset angle with the surface of the display screen. When the user's line of sight is perpendicular to the surface of the display screen, the viewing experience is better.

[0058] It can be seen from the above scheme that the target opening angle of the display screen of the household appliance is determined according to the height range of the user, and the target opening angles corresponding to users of different heights are different. When the display screen is opened according to the target opening angle, the opened display screen faces the face of the user in a standing state, so that different users can face the head and face of the display screen when standing, with a better viewing angle. There is no need for the user to bend over or squat to obtain a better viewing angle, and the display screen can be automatically adjusted to the target opening angle according to the user's height, thereby improving the user experience.

[0059] In actual applications, there are situations where multiple users stand in front of a household appliance and are all detected. When multiple users are detected, the target opening angle of the display screen can be determined in the following way: calculate the relative distance between each user and the household appliance, and determine the target opening angle of the display screen based on the height range of the user who is closest to the household appliance.

[0060] For example, the relative distance between the user and the household appliance can be determined according to the time when the infrared receiver receives the reflected light corresponding to the infrared light emitted by the infrared transmitter.

[0061] In actual applications, there is a situation where one user operates a household appliance and then another user continues to operate the household appliance. In order to enable each user to have a better viewing angle when viewing the display screen, in an embodiment of the present invention, when a change in the height range of the user is detected, an updated height range can be obtained. An updated opening angle corresponding to the updated height range is determined, and according to the updated opening angle, the opening angle of the display screen is adjusted to the updated opening angle based on the opening angle corresponding to the current position of the display screen.

[0062] For example, refer to Figure 4 , the target opening angle corresponding to the user with height H1 is α, then the user with height H1 walks away, and the user with height H2 comes to the home appliance, and it is determined that the updated opening angle corresponding to the user with height H2 is θ, then the display screen 30 is controlled to continue to rotate β, so that after the display screen 30 rotates β, the opening angle is θ, θ=α+β.

[0063] In the embodiment of the present invention, the height range of the user may be obtained periodically to determine whether the height range of the user changes.

[0064] In the embodiment of the present invention, when an infrared detector and an infrared receiver are used to obtain the height of a user, the lowest infrared detector can be controlled to be turned on periodically to monitor whether there is a user and to obtain the height range of the user in a timely manner when there is a user.

[0065] In a specific implementation, after the display screen is opened according to the target angle, the display screen can also be controlled to close when a display screen closing operation is received to restore the display screen to its initial position, thereby protecting the display screen, reducing the possibility of damage to the display screen, and saving energy consumption.

[0066] In an embodiment of the present invention, when the user is not detected for a preset time, the display screen can be triggered to close. Or when the operation of the household appliance is detected to be completed, the display screen can be triggered to close. Other conditions can also be set, and when the set conditions are met, the display screen is triggered to generate a closing operation. For example, when it is detected that the user closes the drum cover of the washing machine, the display screen is triggered to close. For another example, when it is detected that the washing operation is triggered to start, the display screen is triggered to generate a closing operation.
