[0033] The present application provides a cleaning device, including a door body 100 in any of the following embodiments, and also including an inner tank with a cleaning cavity, the door body 100 is rotatably connected to the inner tank, and the door body 100 can cover the inner tank to close the cleaning cavity, so that the interior of the cleaning cavity can be used for cleaning.

[0034] See also Figure 1 and Figure 2 , Figure 1 and Figure 2 All of them show the structural schematic diagrams of the door body 100 in an embodiment of the present application. An embodiment of the present application provides a door body 100. In this embodiment, the door body 100 is used for a cleaning device taking a dishwasher as an example. In other embodiments, the door body 100 can also be applied to other electrical appliances, such as a dryer, steaming equipment, etc.

[0035] like Figure 1 and Figure 2 As shown, the door body 100 includes a main body 110 and a rotating screen 120. The main body 110 includes a front end face 111 with a placement groove 112. Generally, the front end face 111 is the end face of the door body 100 away from the cleaning chamber. The rotating screen 120 is rotatably connected to the main body 110 around a rotation axis. Figure 4 As shown, the rotating screen 120 is rotatably connected to the main body 110 via a screen shaft 150, and the rotating screen 120 rotates around the central axis of the screen shaft 150. More preferably, there are two screen shafts 150, which are coaxially arranged and respectively located at both ends of the rotating screen 120, so that the rotating screen 120 with a longer length is stable when rotating.

[0036] The rotating screen 120 is configured to be able to Figure 2 The closed position shown and Figure 1 between the open positions shown. Figure 3 The rotating screen 120 includes a screen surface 121, and the screen surface 121 is used to display the content displayed on the screen. Figure 2 As shown, when the rotating screen 120 is in the closed position, at least part of the rotating screen 120 is accommodated in the placement groove 112 and the screen surface 121 is parallel to the front surface 111. Preferably, as shown in FIG. Figure 2As shown, when the rotating screen 120 is in the closed position, the rotating screen 120 is completely accommodated in the placement groove 112 to prevent the rotating screen 120 from protruding from the front surface 111 when not in use, thereby preventing the rotating screen 120 from bumping or injuring the user. Figure 1 As shown, when the rotating screen 120 is located at the open position, at least a portion of the rotating screen 120 protrudes from the placement slot 112 and the screen surface 121 is inclined relative to the front surface 111 .

[0037] like Figure 2 As shown, in one embodiment, the rotation angle of the rotating screen 120 from the closed position to the open position is β, 35°≤β≤70°, and the user tilt setting is relatively higher than the rotating screen 120, which makes it easier for the user to see the content displayed on the screen surface 121, thereby optimizing the user experience. It can be understood that the higher the height of the cleaning device and the door body 100, that is, the closer to the user's horizontal line of sight, the smaller the required angle between the rotating screen 120 and the front face 111, and the smaller the rotation angle of the rotating screen 120 to the open position.

[0038] like Figure 4 As shown, in one embodiment, the door body 100 further includes a driving member 130 and a transmission assembly 140, wherein the driving member 130 is used to provide kinetic energy for the rotation of the rotating screen 120. The transmission assembly 140 is transmission-connected between the driving member 130 and the rotating screen 120 to drive the rotating screen 120 to rotate around the rotation axis.

[0039] like Figure 4 and Figure 5 As shown, in one embodiment, the transmission assembly 140 includes a connecting rod assembly 141 connected to the output shaft 131 of the driving member 130 and a rotating plate 142 fixedly connected to the rotating screen 120, the rotating plate 142 includes a first connection 1421 and a second connection 1422 that are spaced apart, and one end of the connecting rod assembly 141 away from the driving member 130 is rotatably connected to the first connection 1421, and the central axis of the second connection 1422 coincides with the rotation axis, so that the connecting rod assembly 141 can realize the rotation of the rotating plate 142 around the rotation axis by driving the first connection 1421 to move.

[0040] like Figure 5As shown, in one embodiment, the connecting rod assembly 141 includes an active rod 1411 and a driven rod 1412 that are rotatably connected, the end of the active rod 1411 away from the driven rod 1412 is connected to the output shaft 131 of the driving member 130, and the end of the driven rod 1412 away from the active rod 1411 is connected to the first connection 1421, so that the connecting rod assembly 141 and the rotating plate 142 together form a four-bar structure, wherein the four-bar structure is respectively the active rod 1411, the driven rod 1412, the first connection 1421 to the second connection 1422 of the rotating plate 142, and the second connection 1422 of the rotating plate 142 to the active rod 1411 connected to one end of the output shaft 131 (in this embodiment, it is the fixed plate 113 described below).

[0041] like Figure 6 As shown, in one embodiment, the connecting rod assembly 141 includes a sliding member 1413 protruding from the driven rod 1412, and the main body 110 also includes a fixing plate 113, and the fixing plate 113 is provided with a sliding groove 1131 corresponding to the sliding member 1413, and the sliding member 1413 is slidably arranged in the sliding groove 1131, so that the sliding member 1413 and the driven rod 1412 that rotates synchronously with the sliding member 1413 can rotate under the guidance of the sliding groove 1131, so that the rotation of the driven rod 1412 and the transmission of the transmission assembly 140 are more stable. Figure 5 and Figure 6 In the embodiment, the fixing plate 113 is also used to fix the driving member 130 to facilitate the overall assembly and improve the assembly efficiency and stability.

[0042] When the sliding member 1413 is Figure 7 and Figure 6 When the rotating screen 120 abuts against the two ends of the sliding groove 1131, the rotating screen 120 is respectively located as shown in FIG. Figure 2 and Figure 1 The closed position and the open position shown in FIG. Figure 7 When the rotating screen 120 abuts against the sliding groove 1131 as shown, the rotating screen 120 is located as shown in FIG. Figure 2 When the sliding member 1413 is as shown in the closed position; Figure 6 When the rotating screen 120 abuts against the sliding groove 1131 as shown, the rotating screen 120 is located as shown in FIG. Figure 1 Shown in open position.

[0043] In such Figure 5 In one of the embodiments shown, the connecting rod assembly 141 further includes a first rotating shaft 143 for rotatably connecting the active rod 1411 and the driven rod 1412 , and the first rotating shaft 143 is coaxially arranged with the sliding member 1413 .

[0044] In such Figure 8In one of the embodiments shown, the sliding member 1413 is detachably connected to the first rotating shaft 143 coaxially arranged with the sliding member 1413. When the sliding member 1413 is connected to the first rotating shaft 143, the sliding member 1413 abuts against the driven rod 1412 or the first rotating shaft 143 abuts against the fixed plate 113. In this embodiment, the outer diameter of the sliding member 1413 is greater than the outer diameter of the first rotating shaft 143. Optionally, the outer circumference of the first rotating shaft 143 is provided with an external thread, and the inner diameter of the sliding member 1413 is provided with an internal thread. The first rotating shaft 143 and the sliding member 1413 are threadedly connected. At this time, when the sliding member 1413 is connected to the first rotating shaft 143, the sliding member 1413 abuts against the driven rod 1412. In other embodiments, the outer diameter of the sliding member 1413 is smaller than the outer diameter of the first rotating shaft 143. Optionally, the outer periphery of the sliding member 1413 is provided with an external thread, and the inner diameter of the first rotating shaft 143 is provided with an internal thread. The first rotating shaft 143 and the sliding member 1413 are threadedly connected. At this time, when the sliding member 1413 is connected to the first rotating shaft 143, the first rotating shaft 143 abuts against the fixed plate 113 to prevent the sliding member 1413 and the first rotating shaft 143 from swinging in the axial direction of the first rotating shaft 143, causing transmission instability of the transmission assembly 140.

[0045] like Figure 5 As shown, in one embodiment, the connecting rod assembly 141 further includes a second rotating shaft 144 for rotatably connecting the driven rod 1412 and the rotating plate 142. In other embodiments not shown, the second rotating shaft 144 is coaxially arranged with the sliding member 1413. At this time, the sliding member 1413 is detachably connected to the second rotating shaft 144 coaxially arranged with the sliding member 1413, and when the sliding member 1413 is connected to the second rotating shaft 144, the sliding member 1413 abuts against the driven rod 1412 or the second rotating shaft 144 abuts against the fixed plate 113.

[0046] In other embodiments not shown, the sliding member 1413 may also be directly connected to the end surface of the driven rod 1412 facing the fixed plate 113 , and is coaxially arranged with both the first rotating shaft 143 and the second rotating shaft 144 .

[0047] A cleaning device taking an embedded dishwasher as an example usually requires a convex or concave handle to be provided on the front end surface 111, but the convex or concave handle will destroy the integrity and aesthetics of the cabinet, and the convex handle may easily injure the user, while the concave handle is limited by the door body 100 and the display screen, and has the problem of insufficient handle depth and too low height, thus affecting the user experience.

[0048] In one embodiment, the rotating screen 120 also includes a handle surface 122 arranged opposite to the screen surface 121, and the handle surface 122 is recessed with a handle groove 123, so that the user can pull the rotating screen 120 through the handle groove 123, and can also be used to open and close the door body 100, effectively solving the problem of the handle of the existing built-in dishwasher being convex or concave, causing the handle to hit people or affect the screen position.

[0049] In one of the embodiments, a side wall of the handle groove 123 is a force-bearing surface 1231, and the force-bearing surface 1231 is inclined relative to the screen surface 121. It can be understood that when the rotating screen 120 is in the open position, it is easier to apply force when the angle between the force-bearing surface 1231 and the front end surface 111 is an acute angle less than 45°. The selection of the angle α between the force-bearing surface 1231 and the screen surface 121 is affected by the rotation angle β of the rotating screen 120. In the present embodiment, the angle between the force-bearing surface 1231 and the screen surface 121 is α, 0°≤α-β≤45°.

[0050] In the above scheme, by setting a rotating screen 120 that is rotatable relative to the main body 110, the space on the front side of the door body 100 is effectively utilized, and the choice of the rotating screen 120 is not limited, so a larger screen can be used. At the same time, the problem that the user needs to bend over or squat to use the screen when it is located on the front end surface 111 of the door body 100 is solved.

[0051] 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.

[0052] 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.
