[0036] In one embodiment of the present application, a dishwasher is provided, comprising the door body 10 of any of the following embodiments, and also comprising an inner tank with a cleaning cavity, the cleaning cavity being used to hold and clean tableware, the door body 10 covering the inner tank and enclosing the cleaning cavity together with the inner tank.

[0037] See also Figure 1 , Figure 1 A schematic structural diagram of a door body 10 in an embodiment of the present application is shown. The door body 10 provided in an embodiment of the present application can be applied to a dishwasher, and can also be applied to any other electrical appliance, such as a washing machine, a steam oven, etc.

[0038] like Figure 1 As shown, the door body 10 includes a rotating screen 100 as described in any of the following embodiments, and also includes an inner door 300, an outer door 200 and a frame 400 sandwiched between the inner door 300 and the outer door 200, and the fixing member 110 in the rotating screen 100 is connected to the frame 400.

[0039] Combination Figure 2 As shown, Figure 2 The structure diagram of the rotating screen 100 in one embodiment of the present application is shown. In one embodiment of the present application, a rotating screen 100 is provided, which can be applied to a dishwasher, or to any other electrical appliance, such as a washing machine, a steam oven, etc. In the embodiment provided by the present application, the rotating screen 100 is applied to a dishwasher to display the washing process and washing time of the dishwasher, and is installed on the above-mentioned door body 10.

[0040] like Figure 2 and Figure 3 As shown, the rotating screen 100 includes a fixing member 110, a rotating member 120 and a back plate 130, and also includes a screen assembly 140. The screen assembly 140 is connected to the end surface of the rotating member 120 away from the back plate 130 for display.

[0041] like Figure 2 As shown, the fixed member 110 includes a mounting surface 111 with a mounting groove 112, which is used to mount the rotating member 120. The rotating member 120 is rotatably connected to the fixed member 110 around a rotation axis and can rotate between an open position and a closed position. Figure 2 As shown, when the rotating member 120 is in the open position, the rotating member 120 partially protrudes from the mounting surface 111, so that there is a gap between at least a portion of the rotating member 120 and the mounting surface 111, as shown in FIG. Figure 2 As shown, in this embodiment, the rotation axis is located at the top of the rotating member 120. When the rotating member 120 is in the open position, there is a gap between the end of the rotating member 120 away from the rotation axis (i.e., the lower end) and the mounting surface 111. When a person's hand is inserted into the existing gap, there is a risk of pinching the hand. Figure 3 As shown, when the rotating member 120 is in the closed position, the rotating member 120 is at least partially inserted into the mounting groove 112. In the present embodiment, when the rotating member 120 is in the closed position, at least the end surface of the rotating member 120 facing the mounting groove 112 is completely located in the mounting groove 112. At this time, there is no gap between the rotating member 120 and the mounting surface 111.

[0042] Combination Figure 4 As shown, the rotating member 120 includes a main body 121 and a back plate 130 connected to the main body 121. The back plate 130 includes a main body 131 and a shielding portion 132 connected to each other. The main body 131 is located on one side of the main body 121 facing the mounting groove 112, and as shown in FIG. Figure 2 and Figure 4 As shown, the shielding portion 132 extends from the body 131 toward the bottom of the mounting groove 112 so that when the rotating member 120 is located at Figure 2 and Figure 4When in the open position shown in FIG. 1 , the shielding portion 132 at least partially shields the gap between the main body 121 and the mounting surface 111. Figure 4 As shown, if there is no shielding portion 132, the space between the body 131 and the mounting surface 111 is a gap, but in the case of Figure 4 In the illustrated embodiment, the shielding portion 132 shields part of the gap, thereby reducing the size of the space that can be inserted into and pinched, thereby reducing the risk of pinching.

[0043] In the above scheme, a back plate 130 with a shielding portion 132 is provided on the side of the main body 121 of the rotating member 120 facing the mounting groove 112, and the shielding portion 132 extending toward the bottom of the mounting groove 112 is used to limit the gap between the rotating member 120 and the mounting surface 111 when the rotating member 120 is in the open position, thereby reducing the size of the space that can be inserted and pinched by hands, thereby reducing the risk of pinching hands, which not only improves the safety of the rotating screen 100, but also enhances the safety and convenience of the user during use.

[0044] like Figure 7 As shown, in one embodiment, the body 131 covers the main body 121 in the axial direction of the rotation axis, and shielding portions 132 are respectively provided at both ends of the main body 131 along the axial direction of the rotation axis, so that it is difficult to insert the hand between the main body 121 and the mounting surface 111 from both ends of the main body 131 in the axial direction of the rotation axis, thereby avoiding the hand being pinched due to the hand being inserted between the main body 121 and the mounting surface 111 from the side of the main body 121.

[0045] In some embodiments, the shielding portion 132 extends in a direction perpendicular to the rotation axis to shield the opening of the gap between the main body 121 and the mounting surface 111 in the axial direction of the rotation axis, thereby preventing the hand from extending into the gap between the main body 121 and the mounting surface 111 in the axial direction of the rotation axis, thereby preventing the hand from being pinched.

[0046] In some embodiments, Figure 4As shown, in the direction perpendicular to the rotation axis, the shielding portion 132 is located at one end of the main body 121 close to the rotation axis, and the maximum distance r between the shielding portion 132 and the rotation axis is not less than 1 / 2 of the maximum distance R between the main body 121 and the rotation axis, that is, r≥R. In the direction from the rotation axis of the main body 121 to the direction away from the rotation axis, the shielding portion 132 covers at least 1 / 2 of the main body 121 to achieve a better anti-pinch effect. It can be understood that when the shielding portion 132 completely blocks the main body 121 in the direction from the rotation axis of the main body 121 to the direction away from the rotation axis, the anti-pinch effect is the best, but when the rotating member 120 is in the open position, the distance between the end of the main body 121 away from the rotation axis and the mounting surface 111 is large. If it is completely shielded by the shielding portion 132, the overall thickness of the rotating screen 100 needs to be large, which is not convenient for use in a small space usage scenario such as the door body 10.

[0047] like Figure 4 As shown, in one embodiment, the fixing member 110 is provided with a placement groove 113, which is provided at the bottom of the installation groove 112 and is arranged in alignment with the shielding portion 132, so that when the rotating member 120 is located in the position as shown in FIG. Figure 6 In the closed position shown, the blocking portion 132 is at least partially located in the mounting slot 112 to prevent the blocking portion 132 from interfering with the rotation of the main body 121 to the closed position.

[0048] like Figure 4 As shown, in one embodiment, the end surface of the shielding portion 132 away from the rotation axis is an arc-shaped surface coaxial with the rotation axis, so that the back plate 130 can be inserted into the placement groove 113 when the back plate 130 rotates with the main body 121. Correspondingly, the end surface of the installation groove 112 away from the rotation axis is an arc-shaped surface adapted to the shielding portion 132.

[0049] like Figure 7 As shown, the rotating screen 100 further includes a driving member 150 and a transmission assembly 160 . The driving member 150 is connected to the transmission assembly 160 via a transmission shaft 151 , and the transmission assembly 160 is connected to the main body 121 so that the driving member 150 drives the main body 121 to rotate relative to the fixing member 110 .

[0050] like Figure 7 As shown, in this embodiment, in the axial direction of the rotation axis, the transmission assembly 160 is located between the two shielding parts 132 and the driving member 150 is located outside the two shielding parts 132, so that the transmission shaft 151 needs to pass through one of the two shielding parts 132, as shown in FIG. Figure 6 and Figure 7As shown, in order to prevent the shielding portion 132 from interfering with the transmission of the transmission shaft 151, an escape opening 1131 for avoiding the transmission shaft 151 is opened in the placement groove 113 for placing the shielding portion 132. Correspondingly, the shielding portion 132 is recessed with a notch 1321 for avoiding the transmission shaft 151 to avoid interference with the transmission shaft 151.

[0051] Combination Figure 4 As shown, in one embodiment, when the rotating member 120 is in the open position, the distance L between the end of the shielding portion 132 away from the body 131 and the mounting surface 111 is not greater than 5 mm. When the distance L between the shielding portion 132 and the mounting surface 111 is very small, the hand can no longer be inserted into the gap between the two, and there is no risk of pinching the hand. It can be understood that the longer the distance of the shielding portion 132 away from the body 131, the smaller the distance between the shielding portion 132 and the mounting surface 111 when the rotating member 120 is in the open position. The distance L between the shielding portion 132 and the mounting surface 111 when the rotating member 120 is in the open position can be controlled by the maximum rotation angle of the rotating member 120 and the length of the shielding portion 132 extending toward the mounting groove 112.

[0052] like Figure 4 and Figure 5 As shown, in one embodiment, the end surface of the main body 131 facing the mounting groove 112 is the back side 1311, and the edge of the back side 1311 is provided with an inclined surface 1312, and the inclined surface 1312 is inclined from the center to the edge of the back side 1311 in a direction away from the mounting groove 112, so that when the hand is located on the inclined surface 1312, even if the hand is clamped between the mounting surface 111 and the back side 1311, the force-bearing area of ​​the hand on the inclined surface 1312 is larger, and the degree of the physical feeling of the hand being clamped can be reduced.

[0053] like Figure 5 As shown, in one embodiment, the inclined surface 1312 is located at one end of the back surface 1311 away from the rotation axis, in this embodiment, that is, the lower end of the back surface 1311, so that the hand can be protected by the inclined surface 1312 when it is placed between the mounting surface 111 and the back surface 1311 from below the main body 121.

[0054] like Figure 5 As shown, in one embodiment, the inclined surface 1312 is located at both ends of the back surface 1311 in the axial direction of the rotation axis and is located on the side of the shielding portion 132 away from the rotation axis. In this embodiment, it is located on both sides of the back surface 1311 and below the shielding portion 132. It is suitable for placing hands between the mounting surface 111 and the back surface 1311 from both sides of the main body 121 and below the shielding portion 132, so that the hands can be protected by the inclined surface 1312.

[0055] like Figure 5As shown, in one embodiment, the inclined surface 1312 is located at both ends of the back surface 1311 in the axial direction of the rotation axis and is located on the side of the shielding portion 132 close to the rotation axis. In the present embodiment, it is located on both sides of the back surface 1311 and above the shielding portion 132, which is suitable for when the hand is placed between the mounting surface 111 and the back surface 1311 from both sides of the main body 121 and above the shielding portion 132, so that it can be protected by the inclined surface 1312.

[0056] In one embodiment, the surface of the inclined surface 1312 is covered with a soft layer to provide a buffer and absorb the force when the hand is pinched. The soft layer is made of a flexible material, such as sponge, soft silicone, etc.

[0057] like Figure 8 As shown, in one embodiment, the back plate 130 is snap-fitted and connected to the main body 121. In other embodiments, the back plate 130 can also be glued or screwed to the main body 121, without limitation.

[0058] like Figure 8 As shown, in one embodiment, the back plate 130 further includes a buckle portion 133, which extends from a portion of the edge of the body 131 toward the direction of the main body 121 to enclose and fit a portion of the peripheral wall of the main body 121, and the buckle portion 133 includes a buckle 1331 protruding toward the peripheral wall of the main body 121, and the buckle 1331 is used to connect to the peripheral wall of the main body 121. In other embodiments, a convex block for clamping can also be provided on the main body 121, and a groove for clamping with it can be provided on the buckle portion 133 accordingly.

[0059] 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.

[0060] 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.
