[0033] See also Figure 1 , Figure 1 The structure diagram of the flip screen assembly 100 in an embodiment of the present application is shown. Figure 2 , Figure 2 A cross-sectional schematic diagram of a flip screen assembly 100 in an embodiment of the present application is shown, wherein a housing 110 is provided with a housing cavity 111, and the housing 110 is provided with an opening 113 communicating with the housing cavity 111, so that the flip screen 120 can pass through the opening 113 and be received in the housing cavity 111 or partially protrude from the housing cavity 111. For ease of description, the surface where the opening 113 is located is described below as the front end surface 112, but this is not limited thereto.

[0034] like Figure 1 and Figure 2 As shown, the flip screen 120 is slidably connected to the housing 110, and the flip screen 120 slides relative to the housing 110, so that the relative position of the flip screen 120 and the housing 110 includes at least Figure 1 The following two cases are shown:

[0035] The flip screen 120 is located at the storage position: the flip screen 120 is stored in the accommodating cavity 111. Figure 1 As shown in (A), Figure 1 (A) is a schematic diagram of the flip screen 120 being in the storage position, which is suitable for storing the flip screen 120 in the accommodating cavity 111 after the flip screen 120 is used, which can solve the problems of the screen being waterproof and waterproof, and the hidden flip screen 120 can be completely hidden inside the shell 110, thereby improving the reliability of the flip screen 120, avoiding damage to the flip screen 120 when it is located on the outside, and avoiding the flip screen 120 protruding and interfering with the user's activities near the dishwasher, and also improving the aesthetics of the dishwasher when the flip screen 120 is not in a working state.

[0036] The flip screen 120 is located at the protruding position, and the flip screen 120 slides relative to the housing 110 so that part of the flip screen 120 passes through the opening 113 and protrudes from the accommodating cavity 111. In the protruding position, the flip screen 120 is configured to be able to rotate relative to the housing 110 so that the flip screen 120 is inclined to the front end surface 112, such as Figure 1 In (B), Figure 1 (B) is a schematic diagram of the flip screen 120 tilted relative to the front face 112. At this time, the flip screen 120 is tilted relative to the front face 112, so that the user can directly see and operate the flip screen 120 when standing, which improves the user's interactive experience. In this embodiment, the flip screen can slide horizontally relative to the housing 110, and the protruding position is the end point of the horizontal sliding path of the flip screen 120 relative to the housing 110.

[0037] In the above scheme, the flip screen 120 slides and rotates relative to the shell 110, so that the flip screen 120 can be tilted at the front end surface 112 to effectively utilize the space at the front end of the door body. Compared with the screen being set at the top of the door body, a larger screen can be selected. Compared with the screen being directly set at the front end surface 112 of the door body, the disadvantage that the user needs to bend over or squat to see and operate the screen is solved. At the same time, the sliding of the flip screen 120 relative to the shell 110 can also make the flip screen 120 be stored in the accommodating cavity 111 after use, which can solve the problems of the screen being waterproof and water vapor-proof, and the hidden flip screen 120 can be completely hidden inside the shell 110, thereby improving the reliability of the flip screen 120 and avoiding damage to the flip screen 120 when it is located on the outside.

[0038] Combination Figure 3 and Figure 4As shown, in one embodiment, the housing 110 is provided with a guide groove 114, and the flip screen 120 is provided with a guide column 121 slidably connected to the guide groove 114. The guide column 121 slides in the guide groove 114, and the flip screen 120 slides along the extension direction of the guide groove 114. Figure 4 As shown, the guide slot 114 includes a starting end 1141 and a rotating end 1142, and the guide post 121 slides between the starting end 1141 and the rotating end 1142. When the guide post 121 is located at the starting end 1141, the flip screen 120 is located at the storage position, and the flip screen 120 is stored in the accommodating cavity 111. When the guide post 121 is located at the rotating end 1142, the flip screen 120 is located at the protruding position, and a part of it protrudes from the accommodating cavity 111 and is rotatably connected to the housing 110. At this time, the flip screen 120 can rotate relative to the housing 110, so that the flip screen 120 can rotate to a position inclined with the front end surface 112.

[0039] Moreover, in Figure 3 In the illustrated embodiment, guide posts 121 are provided on both sides of the flip screen 120 , and the housing 110 is provided with guide grooves 114 disposed oppositely on both sides of the flip screen 120 , so that the flip screen 120 is more stable when sliding relative to the housing 110 .

[0040] like Figure 3 and Figure 4 As shown, in one embodiment, the number of guide grooves 114 located on the same side of the flip screen 120 is at least two, each guide groove 114 is arranged in parallel, and the flip screen 120 is provided with a plurality of guide posts 121 respectively slidably connected to the plurality of guide grooves 114. In this embodiment, the number of guide grooves 114 located on the same side of the flip screen 120 is two, and two guide posts 121 are arranged on the side of the flip screen 120 corresponding to the guide grooves 114, and the two guide posts 121 are respectively slidably connected to the two guide grooves 114. Figure 3 As shown, there are four guide grooves 114 located on both sides of the flip screen 120, with two on each side. Correspondingly, the flip screen 120 is provided with four corresponding guide posts 121.

[0041] In addition, the shell 110 is further provided with a rotating groove 115 respectively connected to the multiple guide grooves 114, each guide groove 114 is correspondingly connected to a rotating groove 115, the rotating groove 115 extends from the rotating end 1142 of the corresponding guide groove 114, and the rotating groove 115 has an arc structure and all the rotating grooves 115 are concentrically arranged, so that when the guide column 121 is located at the rotating end 1142, the flip screen 120 is rotatably connected to the shell 110, and then the guide column 121 rotates along the rotating groove 115, so that when there are multiple guide grooves 114 located on the same side of the flip screen 120, the flip screen 120 is rotatably connected to the shell 110.

[0042] In other embodiments, the number of guide grooves 114 located on the same side of the flip screen 120 may also be one. In this case, when the guide column 121 is located at the rotating end 1142, the flip screen 120 partially protrudes from the accommodating cavity 111 and is rotatably connected to the shell 110. At this time, the flip screen 120 can be rotated relative to the shell 110.

[0043] It can be understood that the rotation angle range of the flip screen 120 relative to the housing 110 is positively correlated with the size of the opening 113 and the length of the flip screen 120 protruding from the accommodating cavity 111. In one embodiment, the length of the guide groove 114 is a, the length of the flip screen 120 along the direction in which the guide groove 114 is set is L, and in, When the flip screen 120 protrudes enough from the accommodating cavity 111 , it is rotated relative to the housing 110 , thereby lowering the height of the opening 113 , thereby improving the strength of the door body and enhancing the aesthetics of the door body.

[0044] Wherein, a<L, so that when the guide post 121 is located at the starting end 1141, the flip screen 120 is received in the accommodating cavity 111. When the guide post 121 is located at the rotating end 1142, the flip screen 120 partially protrudes from the accommodating cavity 111, and the length of the guide groove 114 is avoided to be greater than the length required to achieve the above effect, thereby preventing the thickness of the housing 110 from being too large, and also avoiding the ineffective energy consumption caused by the ineffective sliding distance of the flip screen 120.

[0045] In some embodiments, in order to reduce the height of the opening 113 , the thickness of one end of the flip screen 120 protruding from the accommodating cavity 111 is greater than that of the other end of the flip screen 120 .

[0046] like Figure 2 and Figure 5 As shown, in one embodiment, the flip screen 120 includes a screen surface 122 and a back surface 123 facing each other. The screen surface 122 is a display surface. When the flip screen 120 is tilted toward the front surface 112, the back surface 123 abuts against the shell 110 to support the flip screen 120 through the shell 110. The screen surface 122 is tilted upward, thereby improving the stability of the flip screen 120 when the screen surface 122 is subjected to pressing force.

[0047] like Figure 5 and Figure 6 As shown, in one embodiment, the back surface 123 is concavely provided with a groove 124, such as Figure 2As shown, when the flip screen 120 is inclined to the front face 112, at least one wall surface of the groove 124 abuts against the front face 112 or the side wall surface of the opening 113, so that after the flip screen 120 is rotated, the groove 124 abuts against the housing 110, thereby reducing the interference of the door body on the rotation angle of the flip screen 120, so as to obtain a smaller opening 113. Figure 6 As shown, the groove 124 penetrates the flip screen 120 in a direction perpendicular to the sliding and rotating plane of the flip screen 120 .

[0048] like Figure 5 As shown, in one embodiment, the groove 124 includes a support surface 1241, which is a side wall of the groove 124. When the flip screen 120 is inclined to the front end surface 112, the support surface 1241 is parallel to the front end surface 112 and abuts against the front end surface 112, thereby supporting the flip screen 120 through the shell 110.

[0049] In other embodiments, when the flip screen 120 is inclined toward the front end surface 112 , the bottom wall of the groove 124 may abut against the side wall surface of the opening 113 , so that the flip screen 120 is supported by the housing 110 .

[0050] like Figure 5 and Figure 6 As shown, in one embodiment, the flip screen 120 is capable of protruding out of the back side 123 of one end of the accommodating cavity 111 and is recessed with a handle groove 125 for the user to grasp the flip screen 120 with his hand, so as to solve the problem of the handle protruding outward and hitting people, and the handle being recessed inward in the existing built-in dishwasher, which affects the selection of the screen position.

[0051] like Figure 5 and Figure 6 As shown, in the present embodiment, one side wall of the handle groove 125 is a handle surface 1251, and the handle surface 1251 is inclined relative to both the screen surface 122 and the back surface 123, and the inclination direction is from the back surface 123 to the bottom of the handle groove 125 toward the end away from the flip screen 120 that can protrude from the accommodating cavity 111, so as to facilitate the application of force when the fingers grasp the handle surface 1251.

[0052] like Figure 3 As shown, in one embodiment, the flip screen assembly 100 further includes a driving device 130, which is configured to drive the flip screen 120 to slide and rotate relative to the shell 110, so as to enable the flip screen 120 to automatically switch between the storage position and the protruding position, so as to enable the flip screen 120 to be stored in the accommodating cavity 111 or partially protrude from the accommodating cavity 111 and tilt to the front end surface 112 after rotation.

[0053] like Figure 3As shown, in one embodiment, the driving device 130 includes a driving member 132 and a rocker arm kit 131 which are connected in sequence. The driving member 132 is used to provide kinetic energy for the rotation of the rocker arm kit 131 and the sliding and rotation of the flip screen 120. The rocker arm kit 131 is configured to be able to axially extend and retract the rocker arm kit 131 to change its length. One end of the rocker arm kit 131 away from the driving member 132 is rotatably connected to the flip screen 120.

[0054] like Figure 3 and Figure 5 As shown, the rocker arm kit 131 includes a driving rocker arm 1311 and a telescopic rocker arm 1312. The driving rocker arm 1311 is connected to the output shaft of the driving member 132 so as to swing under the drive of the driving member 132. The telescopic rocker arm 1312 can be slidably sleeved along its axial direction and the outer periphery of the driving rocker arm 1311, thereby realizing the axial extension and contraction of the rocker arm kit 131 to change the length, and the end of the telescopic rocker arm 1312 away from the driving rocker arm 1311 is rotatably connected to the flip screen 120, so that the flip screen 120 can slide along the guide groove 114 and the rotation groove 115, thereby avoiding the interference of the driving device 130 with the sliding and rotation directions of the flip screen 120.
