[0032] In one embodiment of the present application, a cleaning device is provided, which can be a dishwasher by way of example. The cleaning device includes an inner tank having a cleaning cavity, and also includes a door body 100 in any of the following embodiments, which can cover the inner tank to seal the cleaning cavity for easy cleaning in the cleaning cavity.

[0033] See also Figure 1 , Figure 1The structure diagram of the door body 100 in one embodiment of the present application is shown. The door body 100 provided in one embodiment of the present application includes a main body 110, a rotating screen 120, an axis assembly structure 130 as described in any of the following embodiments, a driving member 140 and a transmission assembly 150. The main body 110 includes a front end surface 112 with a placement groove 111, and the rotating screen 120 is rotatably connected to the main body 110 around a rotation axis, and the rotating screen 120 has the following Figure 1 The open position shown and Figure 4 In the present embodiment, the door body 100 further comprises a rotating shaft 160 coaxially arranged with the rotation axis, and the rotating shaft 160 rotatably connects the rotating screen 120 and the main body 110, so that the rotating screen 120 can rotate relative to the main body 110 around the rotation axis. The rotating screen 120 rotates around the central axis of the screen shaft, and more preferably, there are two screen shafts, which are coaxially arranged and respectively located at the two ends of the rotating screen 120, so that the rotating screen 120 with a longer length is stable when rotating.

[0034] See also Figures 1 to 6 In one embodiment, when the rotating screen 120 is in the closed position, at least a portion of the rotating screen 120 is accommodated in the placement groove 111. Figure 4 In the illustrated embodiment, when the rotating screen 120 is in the closed position, the rotating screen 120 is completely accommodated in the placement groove 111 to prevent the rotating screen 120 from protruding from the front end surface 112 when not in use, thereby preventing the rotating screen 120 from bumping or injuring the user. When the rotating screen 120 is in the open position, at least a portion of the rotating screen 120 protrudes from the placement groove 111.

[0035] The driving member 140 is used to provide kinetic energy for the rotation of the rotating screen 120. Figure 3 and Figure 6 As shown, in one embodiment, the driving member 140 is fixedly connected to the main body 110 .

[0036] See also Figure 3 and Figure 6 In one embodiment, the rotating screen 120 includes a screen surface 121, and the screen surface 121 is used for display and interaction. When the rotating screen 120 is in the closed position, the screen surface 121 is parallel to the front surface 112, so that the screen surface 121 and the front surface 112 are more visually integrated. When the rotating screen 120 is in the open position, the screen surface 121 is tilted relative to the front surface 112, so as to be relatively higher than the user's tilt setting of the rotating screen 120, so that the user can more clearly see the content displayed on the screen surface 121, thereby optimizing the user experience.

[0037] Combination Figure 3 , Figures 6 to 8As shown, the present application further provides a shaft assembly structure 130 , which includes a first assembly part 131 , a second assembly part 132 and a connecting shaft 134 .

[0038] The first assembly member 131 has a base surface 1313 and a first positioning surface 1312 that are intersecting, and a first connecting hole 1311 is formed on the base surface 1313. Figure 3 and Figure 6 As shown, the first assembly part 131 is fixedly connected to the rotating screen 120 and rotates synchronously with the rotating screen 120 .

[0039] The second assembly part 132 is provided with a second connecting hole 1321, and the second assembly part 132 includes a second positioning surface 1322 arranged opposite to the first positioning surface 1312 for abutting cooperation with the first positioning surface 1312, and the second positioning surface 1322 is configured to be movable or rotatable relative to the first positioning surface 1312 to facilitate alignment of the first connecting hole 1311 and the second connecting hole 1321.

[0040] The connecting shaft 134 is detachably inserted into the first connecting hole 1311 and the second connecting hole 1321, and when the connecting shaft 134 passes through the first connecting hole 1311 and the second connecting hole 1321, the second positioning surface 1322 abuts against the first positioning surface 1312, that is, when the first connecting hole 1311 and the second connecting hole 1321 are coaxial, the first positioning surface 1312 and the second positioning surface 1322 are at equal distances from the hole axis.

[0041] When it is necessary to pass the connecting shaft 134 through the first connecting hole 1311 and the second connecting hole 1321 to assemble the first assembly part 131 and the second assembly part 132 into a rotationally connected assembly, first, the second positioning surface 1322 is abutted against the first positioning surface 1312, and the positions of the first connecting hole 1311 and the second connecting hole 1321 are pre-positioned by using the first positioning surface 1312 and the second positioning surface 1322, and when the first connecting hole 1311 and the second connecting hole 1321 are coaxial, the connecting shaft 134 is passed through the first connecting hole 1311 and the second connecting hole 1321, thereby realizing the assembly of the first assembly part 131 and the second assembly part 132 together.

[0042] In one embodiment, the first positioning surface 1312 is a concave arc surface, and the second positioning surface 1322 is a convex arc surface. In this case, the first positioning surface 1312 and the second positioning surface 1322 can rotate relative to each other, and there is a position on the rotation path of the first positioning surface 1312 or the second positioning surface 1322 that can make the first connection hole 1311 and the second connection hole 1321 coaxial, so that the first positioning surface 1312 and the second positioning surface 1322 abut against each other, and the assembly of the connecting shaft 134 is preliminarily positioned. In other embodiments, the first positioning surface 1312 and the second positioning surface 1322 can be planes that can slide relative to each other, and the first positioning surface 1312 and the second positioning surface 1322 abut and slide against each other, so that the assembly of the connecting shaft 134 can be preliminarily positioned.

[0043] like Figure 6 As shown, in one embodiment, the first positioning surface 1312 is an arcuate surface coaxially arranged with the first connecting hole 1311, and the second positioning surface 1322 is an arcuate surface coaxially arranged with the second connecting hole 1321. At this time, the first positioning surface 1312 and the second positioning surface 1322 are arcuate surfaces with equal diameters and coaxially arranged, so that the positions of the first connecting hole 1311 and the second connecting hole 1321 can be directly positioned by abutting the first positioning member and the second positioning surface 1322, so that the first connecting hole 1311 and the second connecting hole 1321 with smaller diameters and not convenient for coaxial limitation can be positioned by the first positioning surface 1312 and the second positioning surface 1322 with larger diameters, thereby solving the positioning problem and improving assembly efficiency.

[0044] like Figure 7 As shown, in one embodiment, the shaft assembly structure 130 also includes a stopper 133, which is located on the path of relative movement or rotation of the first assembly part 131 and / or the second assembly part 132, and is used to limit the range of relative movement or rotation of the first assembly part 131 and the second assembly part 132. In this embodiment, the stopper 133 is connected to the second assembly part 132 and is located on the path of rotation of the first assembly part 131 relative to the second assembly part 132, so as to limit the range of rotation of the second assembly part 132 relative to the first assembly part 131, so as to reduce the difficulty of relative rotation of the first assembly part 131 and the second assembly part 132 during the pre-positioning process to find the coaxial position of the first connecting hole 1311 and the second connecting hole 1321, thereby improving the assembly efficiency. In other embodiments, the stopper 133 can also be connected to the first assembly part 131 and located on the movement or rotation path of the second assembly part 132.

[0045] In such Figure 7 and Figure 8In the illustrated embodiment, in one of the embodiments, the limit member 133 is located in the extension direction of the second positioning surface 1322, and when the connecting shaft 134 is connected to the second connecting hole 1321, one side of the first assembly part 131 abuts against the limit member 133, so that when the first positioning surface 1312 and the second positioning surface 1322 abut, the first assembly part 131 is directly moved or rotated to abut against the limit member 133. At this time, the first connecting hole 1311 and the second connecting hole 1321 are coaxial, and the pre-positioning of the first assembly part 131 and the second assembly part 132 is completed. The connecting shaft 134 can be directly inserted into the coaxial first connecting hole 1311 and the second connecting hole 1321 to complete the assembly, thereby further improving the accuracy of the pre-positioning, reducing the difficulty of assembly, and improving the assembly efficiency. In other embodiments, the limit member 133 is located in the extension direction of the first positioning surface 1312, and when the connecting shaft 134 is connected to the second connecting hole 1321, one side of the second assembly part 132 abuts against the limit member 133, so that when the first positioning surface 1312 and the second positioning surface 1322 abut, the second assembly part 132 is directly moved or rotated to abut against the limit member 133, and at this time, the first connecting hole 1311 and the second connecting hole 1321 are coaxial.

[0046] The transmission assembly 150 is transmission-connected between the driving member 140 and the rotating screen 120, and the transmission assembly 150 includes a second assembly part 132, and also includes an active rod 151 connecting the driving member 140 and the second assembly part 132, one end of the active rod 151 is connected to the output shaft of the driving member 140, and the other end is rotationally connected to an end of the second assembly part 132 away from the first assembly part 131, so that when the driving member 140 rotates, it can drive the active rod 151 to rotate, and then the active rod 151 drives the second assembly part 132 to rotate.

[0047] In one embodiment, the connecting shaft 134 is not coaxially arranged with the rotation axis, so that the rotation of the second assembly 132 in the transmission assembly 150 can drive the rotating screen 120 to rotate around the rotation axis.

[0048] The shaft assembly structure 130 provided in the above scheme is configured by respectively setting a first positioning surface 1312 and a second positioning surface 1322 on the first assembly part 131 and the second assembly part 132, and before installing the connecting shaft 134, the first positioning surface 1312 abuts against the second positioning surface 1322 to pre-position the first connecting hole 1311 and the second connecting hole 1321, so as to make it easier to find the assembly position when the first connecting hole 1311 and the second connecting hole 1321 are coaxial, thereby reducing the difficulty of assembly and improving the assembly efficiency.

[0049] 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.

[0050] 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.
