Description

Technical Field

[0001] The present invention belongs to the technical field of washing equipment, and in particular, relates to a washing equipment and a display screen control method thereof. Background Art

[0002] Washing machines are generally provided with a display screen to display the operating status of the washing machine. Some washing machines also have a display screen with a touch function, and the washing machine can be controlled by touching the display screen.

[0003] The display screen of a washing machine is generally fixedly mounted on the front panel of the shell. Some washing machines also have an inclined panel between the front panel and the top panel for the convenience of user observation. The display screen is mounted on the inclined panel. When the user views or controls the washing machine, the user needs to adjust the face to a height and angle corresponding to the display screen so as to observe and control the display screen at the clearest angle.

[0004] Due to the height difference of human body, people of different heights observe the display screen from different perspectives, and people with different observation perspectives observe the display screen with different display effects. There is a problem that users cannot see the content displayed on the display screen clearly. In order to see the displayed content clearly, users need to adjust the position of their faces themselves, which causes trouble to users.

[0005] In addition, there are situations where the user stands next to the washing machine to observe the screen and does not want to adjust his or her position. There are also situations where the washing machine is installed in a special position or there are other objects in front of the washing machine, which prevents the user from reaching the position in front of the washing machine, resulting in the user being unable to see the display screen clearly.

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0038] In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0039] The washing device determines the deflection angle of the face position in the horizontal direction or the deflection angle in the vertical direction at the initial position of the display screen; according to the size of the deflection angle, the display content of the display screen is adjusted or the rotation deflection angle of the display screen is adjusted to adapt to the observation angle of the user's face position. The user does not need to adjust the face position independently. The display screen can automatically adjust the display content or deflection angle according to the face position to improve the user experience. The washing device first adjusts the display content of the display screen, and when the adjustment of the display content of the display screen cannot meet the demand, the rotation of the display screen is adjusted, which can reduce the frequency of the rotation of the display screen, reduce the rotation loss of the display screen, and increase the service life of the rotation structure of the display screen.

[0040] like Figure 1 As shown, the washing device comprises a panel 1 and a display screen 2 arranged on the panel 1, and the display screen 2 has an initial position.

[0041] In some embodiments, the initial position of the display screen 2 is parallel to the panel 1 .

[0042] In some other embodiments, the initial position of the display screen 2 is not parallel to the panel 1 .

[0043] The initial position of the display screen 2 is a position that matches the viewing angle of most consumers' heights.

[0044] The display screen 2 is rotatably arranged with the washing device. The display screen 2 is installed on the washing device through a driving device.

[0045] In some embodiments, the driving device drives the display screen 2 to rotate in all directions.

[0046] In some embodiments, the driving device drives the display screen to rotate in at least two directions, namely, a horizontal direction and a vertical direction.

[0047] The driving device may adopt an existing driving device, which is not described in detail in this embodiment.

[0048] In some embodiments, the display screen 2 is arranged to protrude from the panel 1 so that the display screen 2 can be rotated.

[0049] In some embodiments, the display screen 2 has an extended state protruding from the panel 1 and a retracted state retracted from the panel 1. In the extended state, the display screen 2 is easy to rotate, and in the retracted state, the display screen 2 fits the panel 1, or an embedded groove is provided on the panel 1, and the display screen 2 is located in the embedded groove to protect the display screen.

[0050] The extended state and the retracted state can be achieved by a telescopic mechanism.

[0051] The display screen is generally rectangular, square, circular, elliptical, etc., and has a horizontal direction and a vertical direction in the initial position.

[0052] Before the washing machine is turned off after washing, the display screen is reset to the initial position.

[0053] like Figure 2 As shown, in the example of a rectangular display screen, the horizontal direction is the font display direction of the display screen, the vertical direction is perpendicular to the horizontal direction, and the horizontal direction and the vertical direction on the display screen intersect at the rotation position of the display screen.

[0054] The best viewing angle is when the face is facing the display screen.

[0055] like Figure 3 As shown, it is the deflection angle θ in the horizontal direction of the face position at the initial position of the display screen.

[0056] like Figure 4 As shown, it is the deflection angle θ in the longitudinal direction of the initial position of the face position on the display screen.

[0057] The washing device comprises a face position detection device 3 for detecting the face position.

[0058] The face position detection device 3 is located on the panel 1 .

[0059] The face position detection device 3 uses radar to detect the face position.

[0060] The face position detection device 3 is located at or close to the rotation position of the display screen 1.

[0061] The control method of the display screen of the washing equipment is: Get face position In some embodiments, the coordinates of the face position are detected by the face position detection device 3, and the coordinates of the middle position between the two eyes are determined as the face position coordinates according to the face model.

[0062] Determine the deflection angle of the face position in the horizontal direction or the deflection angle of the face position in the vertical direction at the initial position.

[0063] When the deflection angle does not exceed the set threshold, adjusting the display content of the display screen; When the deflection angle exceeds a set threshold, the display screen rotation deflection angle is adjusted.

[0064] like Figure 5 As shown, the control method of the display screen of the washing device is: S1. Obtain the face position.

[0065] S2. Determine a deflection angle in the horizontal direction or a deflection angle in the vertical direction of the face position at the initial position.

[0067] S4. Adjust the display content of the display screen.

[0068] S5. Adjust the rotation and deflection angle of the display screen.

[0069] In some embodiments, the problem of unclear display screen after the human body is deflected in the left-right direction of the washing device, that is, after the display screen is deflected in the lateral direction of the initial position of the display screen, is solved. The face position is obtained, and the deflection angle of the face position in the lateral direction at the initial position is determined according to the face position coordinates. When the deflection angle in the lateral direction does not exceed the set threshold, the display content of the display screen is adjusted to improve the clarity of the display screen observed by the human eye at the face position. When the deflection angle in the lateral direction exceeds the set threshold, the rotation deflection angle of the display screen is adjusted so that the face is facing the display screen to ensure the clarity of the display screen observed by the human eye.

[0070] In some embodiments, the problem of the difference in human height in the upper and lower directions of the washing device is solved, that is, the problem that the display screen is not clear after the display screen is deflected in the longitudinal direction at the initial position. The face position is obtained, and the deflection angle of the face position in the longitudinal direction at the initial position is determined according to the face position coordinates. When the deflection angle in the longitudinal direction does not exceed the set threshold, the display content of the display screen is adjusted to improve the clarity of the display screen observed by the human eye at the face position. When the deflection angle in the longitudinal direction exceeds the set threshold, the rotation deflection angle of the display screen is adjusted so that the face is facing the display screen to ensure the clarity of the display screen observed by the human eye.

[0071] Among them, adjusting the display content of the display screen includes: The first adjustment method: adjusting the inclination of the display content of the display screen; And / or, a second adjustment method: adjusting display parameters of display content on the display screen; And / or, a third adjustment method: adjusting the layout of the display content of the display screen.

[0072] That is, in some embodiments, the display content of the display screen is adjusted only by the first adjustment method; in some embodiments, the display content of the display screen is adjusted only by the second adjustment method; in some embodiments, the display content of the display screen is adjusted only by the third adjustment method; in some embodiments, the display content of the display screen is adjusted by the first adjustment method and the second adjustment method; in some embodiments, the display content of the display screen is adjusted by the first adjustment method and the third adjustment method; in some embodiments, the display content of the display screen is adjusted by the second adjustment method and the third adjustment method; in some embodiments, the display content of the display screen is adjusted by the first adjustment method, the second adjustment method, and the third adjustment method.

[0073] In some embodiments, the deflection angle that does not exceed the set threshold includes a first angle range, and when the deflection angle is within the first angle range, adjustment is performed according to a first adjustment method.

[0074] like Figure 6 As shown, the control method of the display screen of the washing device is: S1. Obtain the face position.

[0075] S2. Determine a deflection angle in the horizontal direction or a deflection angle in the vertical direction of the face position at the initial position.

[0076] S3: If the deflection angle does not exceed the set threshold (first angle range), go to step S4; otherwise, go to step S5.

[0077] S4. Adjust the display content of the display screen according to the first adjustment method.

[0078] S5. Adjust the rotation and deflection angle of the display screen.

[0079] In some embodiments, the deflection angle that does not exceed the set threshold includes a first angle range and a second angle range; when the deflection angle is within the first angle range, it is adjusted according to the first adjustment method; when the deflection angle is within the second angle range, it is first adjusted according to the first adjustment method, and then adjusted according to the second adjustment method; wherein the angle in the first angle range is smaller than the angle in the second angle range.

[0080] like Figure 7 As shown, the control method of the display screen of the washing device is: S1. Obtain the face position.

[0081] S2. Determine a deflection angle in the horizontal direction or a deflection angle in the vertical direction of the face position at the initial position.

[0082] S3: If the deflection angle does not exceed the first angle range, proceed to step S4; otherwise, proceed to step S5.

[0083] S4. Adjust the display content of the display screen according to the first adjustment method.

[0084] S5. If the deflection angle does not exceed the second angle range, proceed to step S6; otherwise, proceed to step S7.

[0085] S6. Adjust the display content of the display screen according to the second adjustment method.

[0086] S7. Adjust the rotation and deflection angle of the display screen.

[0087] In some embodiments, the deflection angle that does not exceed the set threshold includes a first angle range, a second angle range and a third angle range; when the deflection angle is within the first angle range, it is adjusted according to the first adjustment method; when the deflection angle is within the second angle range, it is first adjusted according to the first adjustment method, and then adjusted according to the second adjustment method; when the deflection angle is within the third angle range, it is first adjusted according to the first adjustment method, then adjusted according to the second adjustment method, and finally adjusted according to the third adjustment method; wherein the angle in the first angle range is smaller than the angle in the second angle range, which is smaller than the angle in the third angle range.

[0088] like Figure 8 As shown, the control method of the display screen of the washing device is: S1. Obtain the face position.

[0089] S2. Determine a deflection angle in the horizontal direction or a deflection angle in the vertical direction of the face position at the initial position.

[0090] S3: If the deflection angle does not exceed the first angle range, proceed to step S4; otherwise, proceed to step S5.

[0091] S4. Adjust the display content of the display screen according to the first adjustment method.

[0092] S5. If the deflection angle does not exceed the second angle range, proceed to step S6; otherwise, proceed to step S7.

[0093] S6. Adjust the display content of the display screen according to the second adjustment method.

[0094] S7. If the deflection angle does not exceed the third angle range, proceed to step S8; otherwise, proceed to step S9.

[0095] S8. Adjust the display content of the display screen according to the third adjustment method.

[0096] S9. Adjust the rotation and deflection angle of the display screen.

[0097] The displayed content has a proximal side edge close to the deflection direction of the deflection angle, a distal side edge opposite to the proximal side edge, a first connecting side edge and a second connecting side edge located between the proximal side edge and the distal side edge.

[0098] The method for adjusting the inclination of the display content of the display screen is that the display of the near side edge remains unchanged, and the first connecting side edge and the second connecting side edge are respectively rotated toward the center of the display screen with the connection points with the near side edge as the rotation centers.

[0099] like Fig. 9 As shown, in the normal viewing angle direction, the inclination of the displayed content is adjusted before and after comparison. The deflection angle is when the face is deflected to the right by an angle of θ in the horizontal direction, and the first connected side edge and the second connected side edge are rotated by an angle of θ / i toward the center of the display screen with their connection points with the near side edge as the rotation center, where i is a fixed value, or i is negatively correlated with θ.

[0100] i is a fixed value determined in advance, or the correlation between i and θ is determined in advance, and i can be determined after θ is determined.

[0101] The method for adjusting the display parameters of the display content of the display screen is: the display parameters of the display content close to the far side remain unchanged, and the brightness and / or contrast of the display content close to the near side is adjusted.

[0102] The brightness and / or contrast of the display content near the distal edge is increased by θ / second angle upper limit value times, or the brightness and / or contrast of the display content near the proximal edge is gradually increased to θ / second angle upper limit value times from the distal edge to the proximal edge.

[0103] In some embodiments, a line connecting the midpoints of the first connecting side edge and the second connecting side edge is used as a dividing line dividing the side close to the distal side and the side close to the proximal side.

[0104] In some embodiments, the dividing line between the distal side and the proximal side is a line perpendicular to the first connecting side and the second connecting side and parallel to the proximal side or the distal side. The position of the dividing line is determined based on θ, and the distance between the dividing line and the proximal side is positively correlated with θ.

[0105] Fig.10 As shown, in the normal viewing angle direction, the contrast of the displayed content is adjusted before and after. The deflection angle is when the face is deflected to the right by an angle of θ in the horizontal direction, the display parameters of the displayed content between the far side edge and the dividing line remain unchanged, and the brightness and / or contrast of the displayed content between the near side edge and the dividing line are uniformly increased by θ / second angle upper limit value times.

[0106] The display parameters of the display content between the far side edge and the dividing line remain unchanged, and the brightness and / or contrast temperature of the display content between the near side edge and the dividing line gradually increases to θ / second angle upper limit value times.

[0107] The method for adjusting the layout of the displayed content on the screen is: reducing the display area of ​​the displayed content and displaying the displayed content near the far side edge, and / or, adjusting the display area of ​​most of the displayed content, reducing the display area of ​​the remaining displayed content or canceling the display of part of the displayed content.

[0108] The display area of ​​the reduced display content is the third angle lower limit value / θ times the original area.

[0109] When adjusting the display area of ​​most display contents, increase the contrast of most display contents to improve the display effect.

[0110] like Fig.11 As shown, in the normal viewing angle direction, the layout of the display content is adjusted before and after comparison. The deflection angle is to deflect the face to the right by an angle of θ in the horizontal direction, reduce the display area of ​​the display content and display the display content at a position close to the far side edge.

[0111] In some embodiments, the display content is divided into several display modules, and adjusting the display area of ​​most of the display content may be to enlarge the current target display module and reduce or hide other display modules.

[0112] During the process of adjusting the rotation of the display screen, the display content of the display screen gradually returns to normal display. For example, in an embodiment including the first angle, the second angle and the third angle, when the deflection angle θ of the face position exceeds the set threshold, the display screen rotates by an angle Q, and when θ-Q is less than the lower limit of the third angle, the original layout of the display screen is restored; when θ-Q is less than the lower limit of the second angle, the original display parameters of the display screen are restored; when θ-Q is less than the lower limit of the first angle, the inclination of the display content of the display screen is restored.

[0113] In some embodiments, the set screen display direction information can also be received, and the display content of the display screen and the rotation angle of the display screen can be controlled according to the set screen display direction information, so as to facilitate user customization of the display.

[0114] In some embodiments, the deflection angle in the horizontal direction and the deflection angle in the vertical direction of the face position at the initial position are determined. When the deflection angle in the horizontal direction is greater than the deflection angle in the vertical direction, the display content of the display screen is adjusted or the rotation of the display screen is adjusted according to the deflection angle in the horizontal direction; when the deflection angle in the horizontal direction is less than the deflection angle in the vertical direction, the display content of the display screen is adjusted or the rotation of the display screen is adjusted according to the deflection angle in the vertical direction.

[0115] like Fig.12 As shown, the display screen control method of the washing equipment is: S1. Obtain the face position.

[0116] S2. Determine a deflection angle in the horizontal direction and a deflection angle in the vertical direction of the face position at the initial position.

[0117] S3: If the lateral deflection angle is greater than the longitudinal deflection angle, go to step S4; otherwise, go to step S5.

[0118] S4. Perform lateral adjustment at a lateral deflection angle.

[0119] S5. Perform longitudinal adjustment at a longitudinal deflection angle.

[0120] This control method makes adjustments in the direction with a larger deflection angle, which can maximize the adjustment effect.

[0121] In some embodiments, when the deflection angle in the horizontal direction is greater than the deflection angle in the vertical direction, the display screen is first controlled to rotate the deflection angle in the vertical direction, and then the display content of the display screen is adjusted or the rotation of the display screen is adjusted according to the deflection angle in the horizontal direction; when the deflection angle in the horizontal direction is less than the deflection angle in the vertical direction, the display screen is first controlled to rotate the horizontal deflection angle, and then the display content of the display screen is adjusted or the rotation of the display screen is adjusted according to the deflection angle in the vertical direction.

[0122] like Fig.13 As shown, the display screen control method of the washing equipment is: S1. Obtain the face position.

[0123] S2. Determine a deflection angle in the horizontal direction and a deflection angle in the vertical direction of the face position at the initial position.

[0124] S3: If the lateral deflection angle is greater than the longitudinal deflection angle, go to step S4; otherwise, go to step S5.

[0125] S4. First, control the deflection angle of the display screen in the longitudinal direction, and then adjust the display content of the display screen or adjust the rotation of the display screen according to the deflection angle in the transverse direction.

[0126] S5. First, control the deflection angle of the display screen to rotate in the horizontal direction, and then adjust the display content of the display screen or adjust the rotation of the display screen according to the deflection angle in the vertical direction.

[0127] This control method can not only reduce the rotation of the display screen, but also more accurately control the display effect of the display screen on the direction of the face position when the face position is deflected.

[0128] This embodiment also proposes a washing device, including a display screen, which can rotate around the washing device. The washing device controls the display screen according to the above control method, and adjusts the display content of the display screen or the rotation deflection angle of the display screen according to the size of the deflection angle to adapt to the viewing angle of the user's face position. The user does not need to adjust the face position independently. The display screen can automatically adjust the display content or deflection angle according to the face position to improve the clarity of the display screen viewed at the face position, so as to improve the user's experience. First, adjust the display content of the display screen. When the display content of the display screen cannot meet the needs, adjust the rotation of the display screen, which can reduce the frequency of the rotation of the display screen and increase the service life of the display screen rotation structure.

[0129] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for a person skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to replace some of the technical features therein by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions claimed to be protected by the present invention.
