[0026] In one embodiment of the present application, a dishwasher is provided, comprising: Figure 1 The door body 10 shown and described below also includes an inner container with a cleaning cavity, and the door body 10 covers the inner container. The dishwasher has multiple working states, such as cleaning, exhausting and drying, etc.

[0027] like Figure 1 As shown, in one embodiment of the present application, a door body 10 is provided, comprising a panel 200 and a screen assembly 100 in any of the following embodiments, wherein the screen assembly 100 is used to display the working status of the dishwasher. Figure 1 As shown, the screen assembly 100 is disposed on the back side of the panel 200, and the panel 200 is provided with a visible window 210 aligned with the display window 111. Figure 1 As shown, the door body 10 further includes a back plate 300 , the back plate 300 and the panel 200 are covered, and the screen assembly 100 is sandwiched between the back plate 300 and the panel 200 , so that the screen assembly 100 is protected by the panel 200 and the back plate 300 .

[0028] See also Figure 2 , Figure 2 FIG. 1 shows a schematic diagram of the exploded structure of a screen assembly 100 provided in an embodiment of the present application. The present application provides a screen assembly 100, which includes a housing 110 and at least two display screens 120. Figure 2 As shown, the housing 110 is provided with a display window 111, through which the display screen 120 located inside the display window 111 can be seen. Figure 2As shown, the display screen 120 is movably disposed on the housing 110, and each display screen 120 is configured to be movable relative to the display window 111 so that the display screens 120 are sequentially and selectively aligned with the display window 111, and the time difference when adjacent display screens 120 are aligned with the display window 111 is less than 0.2 seconds. When the human eye views an object, the image is formed on the retina and input into the human brain through the optic nerve, and the image of the object is sensed. However, when the object is removed, the impression of the object by the optic nerve does not disappear immediately, but continues for 0.1-0.4 seconds. This phenomenon is called the persistence of vision. Due to the setting of the display window 111, the user can only see the content displayed on the display screen 120 located in the display window 111. When the time difference between adjacent display screens 120 when located in the display window 111 is less than 0.2 seconds, when the user sees the content displayed on the next display screen 120 through the display window 111, the optic nerve's impression of the display content of the previous display screen 120 has not disappeared, so that the static images displayed on each display screen 120 are connected to form a dynamic effect.

[0029] In one embodiment, the dishwasher further includes a display control unit, each display screen 120 is controlled by the display control unit, and the display control unit is configured to switch the display content of the display screen 120 according to the state of the dishwasher, and the display content of all the display screens 120 is combined to form a complete picture corresponding to the state of the dishwasher. For example, when the dishwasher is in the cleaning state, the complete picture of the cleaning state of the dishwasher includes the cleaning state at multiple moments, and each display screen 120 corresponds to displaying a static image of the cleaning state at a single moment. When the multiple display screens 120 are sequentially displayed in front of the user through the display window 111, the content that the user's neural network can receive is a coherent, complete, and multiple-moment cleaning state schematic video. Similarly, when the dishwasher is in the exhaust drying state, the complete picture of the corresponding state of the dishwasher includes the exhaust drying state at multiple moments, and each display screen 120 corresponds to a static picture of the exhaust drying state at a single moment; when the dishwasher's dispenser dispenses dishwashing powder and dishwashing liquid, its complete picture includes static pictures of the dispenser dispensing dishwashing powder and dishwashing liquid at multiple moments, and there are differences between the multiple moments, for example, different amounts of dispensing, and at this time, each display screen 120 corresponds to a static picture of the dispenser dispensing dishwashing powder and dishwashing liquid at a single moment. The other states of the dishwasher are similar and will not be described in detail.

[0030] like Figure 2As shown, in one embodiment, the screen assembly 100 further includes a rotating member 130, each display screen 120 is disposed on the circumference of the rotating member 130, and the rotating member 130 is configured to be rotatable relative to the housing 110. When the rotating member 130 rotates, the display screen 120 located on the circumference of the rotating member 130 moves synchronously with the circumference of the rotating member 130 to be selectively aligned with the display window 111. In other embodiments, the display screen 120 can be moved relative to the housing 110 by a conveyor belt or the like to achieve selective alignment of the display screen 120 with the display window 111.

[0031] like Figure 2 As shown, in one embodiment, the spacing between adjacent display screens 120 is equal, and the rotating member 130 rotates at a uniform speed, so that the time difference when adjacent display screens 120 are aligned with the display window 111 is equal, and the visual perception is better.

[0032] In one embodiment, the number of display screens 120 is 6, and the rotation speed of the rotating member 130 is greater than 240r / min. For every 360 degrees (i.e. 1 turn) rotation of the rotating member 130, 6 display screens 120 will be displayed in sequence in the display window 111. At this time, the rotating member 130 rotates 4 turns per second, i.e., the images displayed by 24 display screens 120 will be displayed in sequence in the display window 111 per second. In other words, the user can see 24 static pictures per second through the display window 111, i.e., 24 frames per second. At this time, the time difference between adjacent display screens 120 when they are located in the display window 111 is 0.0416 seconds, thereby forming a smooth animation or video effect visually.

[0033] Preferably, the rotation speed of the rotating member 130 is between 240r / min and 600r / min. A higher frame rate can make the picture look smoother and more detailed, but for human perception, the range of 24-60 frames is sufficient to satisfy the visual sensory experience from pictures to animations. 60fps (frame rate) means that 60 pictures need to be seen per second. For every 360 degrees (i.e. 1 turn) of the rotating member 130, 6 display screens 120 will be displayed in sequence in the display window 111. When the rotation speed of the rotating member 130 is 600r / min, the rotating member 130 rotates 10 turns per second, i.e., 60 pictures displayed on the display screens 120 will be displayed in sequence in the display window 111 per second. In other words, the user can see 60 static pictures per second through the display window 111, i.e., 60 frames per second. At this time, the time difference between adjacent display screens 120 when they are located in the display window 111 is 0.0166 seconds, thereby forming a smooth animation or video effect visually.

[0034] In one embodiment, the screen assembly 100 further includes a control panel 200, which is connected to the housing 110 and disposed on the plane where the visible panel 200 is located, and the rotating member 130 is controlled by the control panel 200. Exemplarily, by operating the control panel 200, it is possible to control whether the rotating member 130 rotates, thereby switching between visual static display or dynamic display; the rotation speed of the rotating member 130 can also be controlled by the control panel 200, and when the rotation speed of the rotating member 130 is faster, the time difference between adjacent display screens 120 when they are located in the display window 111 is smaller, and the visual dynamic effect is smoother.

[0035] In one embodiment, the screen assembly 100 further includes a driving member, which is connected to the housing 110 and acts on the rotating member 130 to drive the rotating member 130 to rotate, thereby providing rotational power for the rotating member 130. Figure 2 As shown, in this embodiment, the screen assembly 100 also includes a support base 140 fixedly connected to the shell 110, and the two support bases 140 are respectively located at the two ends of the rotating member 130, and the two ends of the rotating member 130 are respectively rotatably connected to the two support bases 140 to limit the rotating member 130 through the support base 140.

[0036] In one embodiment, the driving member is a stepping motor, and each time the driving member drives the rotating member to rotate once, the next display screen 120 located in the display window 111 can be driven to rotate and align to the display window 111, so as to Figure 2 In the embodiment shown, the number of display screens 120 is 6 for example, the central angle corresponding to two adjacent display screens 120 is 60°, and each rotation of the driving member rotates 60°, that is, the step angle of the stepping motor is 60°. Each rotation of the driving member can drive the next display screen 120 to be located opposite to the display window 111.

[0037] The screen assembly 100 provided in the present solution is provided with a display screen 120 that can move relative to the display window 111, and switches the next display screen 120 every less than 0.2 seconds, so as to utilize the phenomenon of visual persistence. When the user sees the content displayed on the next display screen 120 through the display window 111, the impression of the display content of the previous display screen 120 by the optic nerve has not disappeared, so that the static images displayed on each display screen 120 are connected to form a dynamic effect, thereby freeing the user from the dull static display mode and obtaining a better viewing experience.

[0038] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0039] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
