Description

Technical Field

[0001] This utility model relates to the field of dishwasher technology, and in particular to a control panel structure, a door structure, and a dishwasher. Background Technology

[0002] The control panel of a dishwasher typically includes a handle and a display panel. Traditional handle designs usually use a hidden handle or an external handle. Hidden handles require a recessed handle area at the handle position, which can compromise the overall aesthetics to some extent.

[0003] The display panel assembly can be set on the front or tilted on the control panel. However, users generally operate it by tilting it down and looking down. Setting it on the front is not very user-friendly for visual experience, while tilting it will disrupt the overall appearance.

[0004] The existing solution on the market is to provide a structure that electrically controls the rotation of the display screen. However, this structure has problems such as motor noise, slow rotation speed, and high cost because it requires motor control. Utility Model Content

[0005] Therefore, it is necessary to provide a control panel structure, door structure, and dishwasher to address the aforementioned problems.

[0006] A control panel structure includes a panel frame, a display panel assembly, and a manual positioning assembly. The panel frame has an operation port, and a handle is provided on the inner side of the panel frame.

[0007] The display panel assembly is rotatably connected to the panel frame. The display panel assembly can rotate relative to the operating port and form at least a first position and a second position. The rotation axis of the display panel assembly and the panel frame is away from the handle.

[0008] The manual positioning component is used to maintain the position of the display panel assembly when it is in the second position and to reset the display panel assembly from the second position to the first position;

[0009] When the display panel assembly is in the first position, the operation port is closed; when the display panel assembly is in the second position, the operation port is open, exposing the handle.

[0010] In one embodiment, the manual positioning component includes a fixed base, a slider, a lever, and an elastic element. The fixed base is disposed on the panel frame, the slider is disposed on the display panel assembly, and one end of the elastic element is connected to the fixed base and the other end is connected to the slider.

[0011] The fixing base is provided with a first rail, the sliding member is provided with a second rail, and the sliding member is slidably connected to the first rail;

[0012] One end of the shift lever is connected to the fixing base, the other end is slidably connected to the second rail, the second rail is provided with a limiting portion, and when the display panel assembly is in the second position, the shift lever slides to the limiting portion and is clamped with the limiting portion;

[0013] When the display panel assembly is in the first position, the elastic member is in a compressed state, and the elastic potential energy of the elastic member when the display panel assembly is in the first position is less than the elastic potential energy of the elastic member when the display panel assembly is in the second position.

[0014] In one embodiment, the shift lever is a Z-shaped or n-shaped round rod structure, one end of the shift lever is a fixed end, the other end is a movable end, the fixed end is rotatably connected to the fixing base, and the movable end is inserted into the second rail and slidably connected with the second rail

[0015] The second rail is provided with a first curved surface and a second curved surface, the first curved surface is connected with the second curved surface, the limiting portion is formed with a third curved surface, along the sliding direction of the movable end on the second rail, the tangent direction of the end of the first curved surface faces the concave surface of the third curved surface, and the tangent direction of the end of the third curved surface faces the concave surface of the second curved surface;

[0016] The first rail is arranged in a circular arc shape, and the center of the circular arc is located on the rotation axis of the display panel assembly and the panel frame; or, the first rail is arranged in a straight line shape.

[0017] In one embodiment, when the movable end slides to the deepest part of the first curved surface, the included angle between the display panel assembly and the operation opening is a1, when the movable end slides to the deepest part of the second curved surface, the included angle between the display panel assembly and the operation opening is a2, when the movable end slides to the deepest part of the third curved surface, the included angle between the display panel assembly and the operation opening is a3, a3<a1, and a3<a2.

[0018] In one embodiment, the second rail is further provided with a fourth curved surface, when the display panel assembly rotates from the first position to the second position, the sliding member slides from the third position to the fourth position relative to the fixing base, and the distance between the third position and the fourth position is the maximum stroke of the first rail;

[0019] When the slider moves from the fourth position to the third position, the movable end moves from the third surface and the second surface to the fourth surface, leaving a gap between the movable end and the fourth surface.

[0020] In one embodiment, the fixing base includes a mounting base and a fixing cover. The mounting base is fixedly mounted on the panel frame, and the fixing cover is connected to the mounting base. The sliding member is sandwiched between the mounting base and the fixing cover. One of the fixing cover and the sliding member has a mounting groove, and the other forms a limiting post. The limiting post is inserted into the mounting groove. The elastic member is a spring structure, which is assembled in the mounting groove and sleeved on the limiting post.

[0021] In one embodiment, a bushing is further provided between the display panel assembly and the panel frame. The bushing is detachably connected to the panel frame. The bushing has a mounting hole. The display panel assembly has a rotating shaft structure. The rotating shaft structure is inserted into the mounting hole to realize the rotational connection between the display panel assembly and the panel frame.

[0022] In one embodiment, the number of manual positioning components is two, and the two manual positioning components are symmetrically distributed.

[0023] A second aspect of this application provides a door structure, including a glass door panel and a control panel structure as described in any one of the above claims;

[0024] The glass door panel is disposed on the outside of the panel frame, and the glass door panel has a first opening adapted to the operation port. When the display panel assembly is in the first position, the display panel assembly extends into the first opening and is flush with the glass door panel.

[0025] A third aspect of this application provides a dishwasher, including a door structure as described in any of the preceding claims.

[0026] One of the above technical solutions has the following advantages and beneficial effects:

[0027] In the aforementioned dishwasher, the integrated structure—comprising a handle on the inner side of the panel frame, an operation opening in the panel frame, and a rotatable display panel assembly to control the opening and closing of the operation opening—achieves a completely concealed handle and a flat control panel appearance when the operation panel is not in use. By positioning the rotation axis of the display panel assembly away from the handle, space is created when the display panel assembly rotates open, allowing the concealed handle to be exposed through the operation opening. The structure, where the display panel assembly is rotatably connected to the panel frame to form at least a first and a second position, and employing a manual positioning component to maintain the display panel assembly in the second position and reset it to the first position, allows the user to manually switch the display panel assembly between a conveniently operable display state and a flat, handle-hidden state. This mechanical drive for state switching avoids problems such as motor noise, slow rotation speed, and high cost compared to existing electric drive methods. Attached Figure Description

[0046] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0047] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0048] The control panel structure, door structure, and dishwasher of some embodiments of the present invention are described below with reference to the accompanying drawings.

[0049] like Figures 1 to 13 As shown, this embodiment discloses a control panel structure, including a panel frame 10, a display panel assembly 20 and a manual positioning assembly 30. The panel frame 10 has an operation port 101 and a handle 40 is provided on the inner side of the panel frame 10.

[0050] The display panel assembly 20 is rotatably connected to the panel frame 10. The display panel assembly 20 can rotate relative to the operation port 101 and form at least a first position and a second position. The rotation axis of the display panel assembly 20 and the panel frame 10 is away from the handle 40.

[0051] The manual positioning component 30 is used to maintain the position of the display panel assembly 20 in the second position and to reset the display panel assembly 20 from the second position to the first position;

[0052] When the display panel assembly 20 is in the first position, the operation port 101 is closed; when the display panel assembly 20 is in the second position, the operation port 101 is open, exposing the handle 40.

[0053] This application discloses a control panel structure. Through an integrated structure including a handle 40 on the inner side of a panel frame 10, an operation port 101 on the panel frame 10, and a rotatable display panel assembly 20 to control the opening and closing of the operation port 101, the handle 40 is completely hidden when the control panel is not in use, resulting in a flat appearance. By positioning the rotation axis of the display panel assembly 20 away from the handle 40, space is created when the display panel assembly 20 is rotated open, allowing the hidden handle 40 to be exposed through the operation port 101. The display panel assembly 20 is rotatably connected to the panel frame 10, forming at least a first position and a second position. A manual positioning component 30 is used to hold the display panel assembly 20 in the second position and reset it to the first position. Users can manually switch the display panel assembly 20 between a convenient operating state and a flat state with the handle 40 hidden, achieving mechanical drive for state switching. Compared to existing electric drive methods, this avoids problems such as motor noise, slow rotation speed, and high cost.

[0054] The panel frame 10 can serve as the installation base and supporting body of the entire control panel structure. The panel frame 10 has an operation port 101 and a hidden handle 40 on its inner side. It should be noted that the inner side of the panel frame 10 faces the inner tub of the dishwasher, and the outer side of the panel frame 10 faces the user.

[0055] The display panel assembly 20 can be rotatably connected to the panel frame 10, for example, via a pivot or hinge. The axis of rotation of the display panel assembly 20 and the panel frame 10 is limited away from the handle 40. This design ensures that when the display panel assembly 20 rotates, it can effectively cover or expose the handle 40 within its rotation range. The display panel assembly 20 can rotate relative to the operating port 101, forming at least a first position and a second position. In the first position, the display panel assembly 20 closes the operating port 101, and in the second position, it opens the operating port 101. Therefore, rotating the display panel assembly 20 controls the opening and closing of the operating port 101. It should be noted that in the first position, the display panel assembly 20 is parallel to the plane of the operating port 101, or the angle between the planes of the display panel assembly 20 and the operating port 101 is small, preventing the user's hand from operating the handle 40 through the gap between the display panel assembly 20 and the operating port 101. Alternatively, the display panel assembly 20 may include a display and an operation panel.

[0056] The manual positioning component 30 can be used to maintain and reset the state of the display panel assembly 20. Specifically, when the user applies a force to push the display panel assembly 20 and rotates it to the second position, the manual positioning component 30 can keep it in that position, making it convenient for the user to operate the handle 40 stably. When it is necessary to switch the operation port 101 from the open state to the closed state, the manual positioning component 30 can reset the display panel assembly 20 from the second position to the first position. For example, when the user applies a force to push the display panel assembly 20, the manual positioning component 30 resets it.

[0057] The handle 40 may be located inside the panel frame 10 and is a hidden component. Whether the handle 40 is exposed depends on the position control of the display panel assembly 20. When the display panel assembly 20 is in the first position, the handle 40 is covered by the display panel assembly 20; when the display panel assembly 20 is in the second position, the handle 40 is exposed through the gap between the operation port 101 and the display panel assembly 20, allowing the user to pull it to open the dishwasher door.

[0058] like Figures 3 to 7 As shown, in addition to the features of the above embodiments, this embodiment further defines that: the manual positioning component 30 includes a fixed base 31, a sliding member 32, a lever 33 and an elastic member 34. The fixed base 31 is disposed on the panel frame 10, the sliding member 32 is disposed on the display panel assembly 20, and one end of the elastic member 34 is connected to the fixed base 31 and the other end is connected to the sliding member 32.

[0059] The fixed base 31 has a first track 310, and the sliding member 32 has a second track 320. The sliding member 32 is slidably connected to the first track 310.

[0060] One end of the lever 33 is connected to the fixed base 31, and the other end is slidably connected to the second track 320. The second track 320 has a limiting part 3210. When the display panel assembly 20 is in the second position, the lever 33 slides to the limiting part 3210 and engages with the limiting part 3210.

[0061] When the display panel assembly 20 is in the first position, the elastic element 34 is in a compressed state, and the elastic potential energy of the elastic element 34 when the display panel assembly 20 is in the first position is less than the elastic potential energy of the elastic element 34 when the display panel assembly 20 is in the second position.

[0062] The above embodiment further defines that by setting a second track 320 with a limiting part 3210 and a lever 33 slidably connected thereto, when the lever 33 slides into the limiting part 3210, the display panel assembly 20 is mechanically self-locked in the second position, thereby ensuring that the operation port 101 remains open and ensuring that the user can reliably operate the handle 40; by setting the elastic element 34 so that the elastic potential energy of the display panel assembly 20 in the second position is greater than that in the first position, the display panel assembly 20 is provided with a driving force for automatic reset from the second position to the first position.

[0063] The fixing base 31 can be fixedly mounted on the panel frame 10. The fixing base 31 may be provided with a first track 310 to guide the sliding of the slider 32. The first track 310 determines the sliding path of the slider 32 relative to the fixing base 31, thereby limiting the maximum angle of rotation of the display panel assembly 20 relative to the operation port 101. For example, the fixing base 31 is provided with a positioning hole 302 and a fourth mounting hole 303. The panel frame 10 is provided with a positioning post 130 and a fourth screw post 140. After the positioning post 130 is inserted into the positioning hole 302, the fixing base 31 is initially positioned on the panel frame 10. Subsequently, the fourth mounting hole 303 and the fourth screw post 140 are fixedly connected by screws.

[0064] The slider 32 may be fixedly mounted on the display panel assembly 20 and slidably connected to the first track 310. When the display panel assembly 20 rotates, the slider 32 will move along the first track 310. The slider 32 may have a second track 320, and the second track 320 has a limiting part 3210. The limiting part 3210 may be a recess, a slot, or other structure. The slider 32 converts the rotational movement of the display panel assembly 20 into its own sliding movement relative to the fixed base 31 along the first track 310. For example, there are two first tracks 310, and the slider 32 is provided with two protrusions 321, which are slidably connected to the two first tracks 310 respectively.

[0065] The lever 33 can be connected at one end to the fixed base 31 and at the other end to the second track 320 on the slider 32. The lever 33 can be used as a motion conversion and positioning component. One end of the lever 33 slides in the second track 320. When it slides to the limit part 3210, under external force, such as when the user releases his hand, one end of the lever 33 will be locked into the limit part 3210, thereby realizing mechanical self-locking and keeping the display panel assembly 20 stably in the second position.

[0066] The elastic element 34 may be connected to the fixed base 31 at one end and the sliding element 32 at the other end. When the sliding element 32 moves, it will stretch or compress the elastic element 34. For example, when the display panel assembly 20 is in the first position, the elastic element 34 is in a compressed state. In the second position, the elastic potential energy stored in the elastic element 34 is greater than that in the first position. When the display panel assembly 20 is in the second position and engages with the limiting part 3210, the elastic element 34 is in a high potential energy state. Once the user applies force to disengage the lever 33 from the limiting part 3210, the elastic force released by the elastic element 34 will drive the sliding element 32 and the display panel assembly 20 to automatically reset to the first position.

[0067] like Figure 3 , Figures 7 to 11 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the lever 33 is a Z-shaped or n-shaped round rod structure, one end of the lever 33 is a fixed end 331, and the other end is a movable end 332. The fixed end 331 is rotatably connected to the fixed base 31, and the movable end 332 is inserted into the second track 320 and slidably connected to the second track 320.

[0068] The second track 320 is provided with a first curved surface 3211 and a second curved surface 3212. The first curved surface 3211 is connected to the second curved surface 3212. The limiting part 3210 forms a third curved surface 3213. Along the sliding direction of the movable end 332 in the second track 320, the tangent direction of the end of the first curved surface 3211 faces the concave surface of the third curved surface 3213, and the tangent direction of the end of the third curved surface 3213 faces the concave surface of the second curved surface 3212.

[0069] The first rail 310 is arranged in a circular arc shape, and the center of the circular arc is located on the rotation axis of the display panel assembly 20 and the panel frame 10; or, the first rail 310 is arranged in a straight line.

[0070] Herein, the shifting lever 33 may be a Z-shaped or n-shaped round rod structure, two ends of the shifting lever 33 are defined as a fixed end 331 and a movable end 332 respectively, the fixed end 331 and the fixed base 31 can be rotatably connected through a shaft or a hole, and the movable end 332 is inserted into and slidably connected to the second rail 320. The second rail 320 may be sequentially provided with a first curved surface 3211, a second curved surface 3212, and a third curved surface 3213 on the limiting portion 3210, the first curved surface 3211 is connected with the second curved surface 3212, and the third curved surface 3213 is located between them or at a specific position;

[0071] Along the sliding direction of the movable end 332, based on that the tangential direction of the end of the first curved surface 3211 faces the concave surface of the third curved surface 3213, when the movable end 332 of the shifting lever 33 slides out from the first curved surface 3211, its movement direction is guided to the recessed area of the third curved surface 3213; based on that the tangential direction of the end of the third curved surface 3213 faces the concave surface of the second curved surface 3212, when the movable end 332 slides out from the third curved surface 3213 of the limiting portion 3210, its movement direction is guided to the recessed area of the second curved surface 3212, so that the movable end 332 is released from the limiting portion 3210; based on the mutual cooperation of the first curved surface 3211, the second curved surface 3212 and the third curved surface 3213, a movement path for guiding the movable end 332 of the shifting lever 33 to slide into and out of the limiting portion 3210 is jointly formed.

[0072] The first rail 310 may be arranged in a circular arc shape or a straight line shape; when the first rail 310 is arranged in a circular arc shape, and the center of the circular arc is located on the rotation axis of the display panel assembly 20, the movement track of the sliding member 32 on the fixed base 31 is concentric with the rotation track of the display panel assembly 20, which reduces the friction force generated due to track mismatch, and makes the movement of the entire manual positioning assembly 30 smoother.

[0073] As Figures 7 to 11 shown, in addition to the features of the above-mentioned embodiments, this embodiment further defines: when the movable end 332 slides to the deepest part of the first curved surface 3211, the included angle between the display panel assembly 20 and the operation opening 101 is a1; when the movable end 332 slides to the deepest part of the second curved surface 3212, the included angle between the display panel assembly 20 and the operation opening 101 is a2; when the movable end 332 slides to the deepest part of the third curved surface 3213, the included angle between the display panel assembly 20 and the operation opening 101 is a3, where a3<a1 and a3<a2.

[0074] Herein, the included angle between the display panel assembly 20 and the operation opening 101 is a1, the included angle between the display panel assembly 20 and the operation opening 101 is a2, and the included angle between the display panel assembly 20 and the operation opening 101 is a3. Based on the angular relationship of a3<a1 and the corresponding curved surface transition, when the movable end 332 of the shift lever 33 slides from the first curved surface 3211 to the third curved surface 3213, the movable end 332 can slightly overshoot the end of the first curved surface 3211 by virtue of inertia or user's pushing force, then be accurately captured by the concave surface of the third curved surface 3213 and guided to the deepest position, so as to realize the clamping connection between the movable end 332 and the limiting portion 3210; meanwhile, based on the angular relationship of a3<a2 and the corresponding curved surface transition, when a user applies a force to make the shift lever 33 slide out from the third curved surface 3213, the movable end 332 can be guided to the second curved surface 3212 along the trend, and the elastic potential energy of the elastic member 34 drives the movable end 332 to reset to the original position.

[0075] Figures 7 to 11 As shown in the figure, in addition to the features of the above-mentioned embodiments, this embodiment further defines that: a fourth curved surface 3214 is further disposed on the second rail 320; when the display panel assembly 20 rotates from the first position to the second position, the sliding member 32 slides from the third position to the fourth position relative to the fixed base 31, and the distance between the third position and the fourth position is the maximum stroke of the first rail 310;

[0076] When the sliding member 32 slides from the fourth position to the third position, the movable end 332 slides sequentially from the third curved surface 3213 and the second curved surface 3212 to the fourth curved surface 3214, and a gap is reserved between the movable end 332 and the fourth curved surface 3214.

[0077] The above embodiment further defines that the fourth curved surface 3214 is disposed at the starting end of the second rail 320, and a gap is reserved between the movable end 332 and the fourth curved surface 3214 when the movable end 332 reaches the reset end point, which not only prevents the component from being damaged due to over-stroke caused by excessive force applied by the user or accidental operation, but also ensures the consistency and reliability of the opening and closing angle of the display panel assembly 20 during long-term use.

[0078] Herein, the fourth curved surface 3214 is disposed on the second rail 320, which is a curved surface area located at the starting end of the second rail 320. When the display panel assembly 20 is at the first position, the movable end 332 of the shift lever 33 stays on the area of the fourth curved surface 3214.

[0079] When the display panel assembly 20 rotates from the first position to the second position, the sliding member 32 slides from the third position to the fourth position relative to the fixed base 31, and the distance between these two positions is defined as the maximum stroke of the first rail 310, so as to determine the maximum rotatable angle range of the display panel assembly 20 and prevent damage caused by over-stroke.

[0080] Specifically, when the display panel assembly 20 is in the first position, the movable end 332 of the lever 33 is stationary at the fourth curved surface 3214. When the upper end of the display panel assembly 20 is pressed, the display panel assembly 20 rotates relative to the operation port 101, and the movable end 332 slides from the fourth curved surface 3214 to the first curved surface 3211. At this time, after the force pressing the display panel assembly 20 is removed, the movable end 332 slides from the first curved surface 3211 to the third curved surface 3213, and the lever 33 and the limit... The position 3210 engages, causing the display panel assembly 20 to remain in the second position and hold there. When the upper end of the display panel assembly 20 is pressed further, the movable end 332 slides out from the third curved surface 3213 and is guided to the second curved surface 3212. At this time, after the force pressing the display panel assembly 20 is removed, driven by the elastic potential energy of the elastic element 34, the movable end 332 slides from the third curved surface 3213 to the fourth curved surface 3214, completing the reset. At this time, the display panel assembly 20 is in the first position.

[0081] When the slider 32 slides from the fourth position to the third position, the corresponding display panel assembly 20 resets from the second position to the first position. The movable end 332 of the lever 33 first slides out from the third curved surface 3213 on the second track 320, then passes through the second curved surface 3212, and finally reaches the fourth curved surface 3214. When the movable end 332 slides to the fourth curved surface 3214, there is a gap between it and the fourth curved surface 3214. That is to say, at the end of the reset movement, the movable end 332 of the lever 33 does not come into contact with the fourth curved surface 3214.

[0082] like Figures 3 to 6 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the fixed base 31 includes a mounting base 311 and a fixed cover 312. The mounting base 311 is fixedly mounted on the panel frame 10, the fixed cover 312 is connected to the mounting base 311, the sliding member 32 is sandwiched between the mounting base 311 and the fixed cover 312, one of the fixed cover 312 and the sliding member 32 is provided with a mounting groove 301, and the other forms a limiting post 3121. The limiting post 3121 is inserted into the mounting groove 301, and the elastic member 34 is a spring structure. The elastic member 34 is assembled in the mounting groove 301 and is sleeved on the limiting post 3121.

[0083] The fixed base 31 may include a mounting base 311 and a fixed cover 312. The mounting base 311 may be fixedly mounted on the panel frame 10, and the fixed cover 312 may be connected to the mounting base 311 to form a cavity for accommodating the sliding member 32. Based on the fact that the fixed cover 312 and the sliding member 32 have a mounting groove 301 on one and a limiting post 3121 on the other, the limiting post 3121 is inserted into the mounting groove 301, which not only provides initial positioning for the fixed cover 312 and the mounting base 311 during assembly, but also provides installation conditions for the elastic member 34. The elastic member 34 may be a spring structure. The mounting groove 301 provides radial constraint for the spring, while the limiting post 3121 plays a centering and guiding role for the spring, ensuring that the spring is always compressed and rebounded along the axis.

[0084] like Figure 1 and Figure 2 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: a bushing 50 is provided between the display panel assembly 20 and the panel frame 10, the bushing 50 is detachably connected to the panel frame 10, the bushing 50 is provided with a mounting hole 501, and the display panel assembly 20 is provided with a rotating shaft structure 211, which is inserted into the mounting hole 501 to realize the rotational connection between the display panel assembly 20 and the panel frame 10.

[0085] The above embodiment further specifies the setting of an independent bushing 50 component, which is designed to be detachably connected to the panel frame 10. This realizes the modularization of the easily worn bearing part in the rotating connection. When wear, loosening or abnormal noise occurs at the rotating part due to long-term use, it is not necessary to replace the entire panel frame 10. Only the bushing 50 needs to be replaced, which reduces the long-term maintenance cost and repair difficulty of the product.

[0086] The bushing 50 is disposed between the display panel assembly 20 and the panel frame 10, and is detachably connected to the panel frame 10 by means such as screws or snap-fit ​​connections. The bushing 50 may have a mounting hole 501, which can cooperate with a pivot on the display panel assembly 20 to achieve a rotatable connection between the display panel assembly 20 and the panel frame 10. It should be noted that there may be two bushings 50, symmetrically distributed on both sides of the panel frame 10, to achieve a stable rotatable connection between the display panel assembly 20 and the panel frame 10.

[0087] In some embodiments, the bushing 50 is provided with a first mounting hole 502, a second mounting hole 503 and a spring-loaded structure 510. Correspondingly, the panel frame 10 is provided with a first screw post 110, a second screw post 120 and a mounting notch 102. The first mounting hole 502 and the second mounting hole 503 are in different directions. The first mounting hole 502 is connected to the first screw post 110 by a screw, the second mounting hole 503 is connected to the second screw post 120 by a screw, and the spring-loaded structure 510 is engaged with the mounting notch 102.

[0088] like Figure 1 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the number of manual positioning components 30 is two, and the two manual positioning components 30 are symmetrically distributed.

[0089] like Figure 1 , Figure 12 and Figure 13 As shown, this embodiment provides a door structure, including a glass door panel 60 and the aforementioned control panel structure;

[0090] The glass door panel 60 is located on the outside of the panel frame 10, and the glass door panel 60 has a first opening 601 adapted to the operation port 101. When the display panel assembly 20 is in the first position, the display panel assembly 20 extends into the first opening 601 and is flush with the glass door panel 60.

[0091] The door structure disclosed in this application, by embedding the control panel structure behind the glass door panel 60 and making the display panel assembly 20 extend into the first opening 601 and be flush with the glass door panel 60 when closed, realizes that the side of the entire door structure facing the user is presented as a flat surface when not in operation, which greatly improves the visual unity and aesthetics of home appliances using glass doors.

[0092] This embodiment provides a dishwasher, including the door structure described above.

[0093] The dishwasher disclosed in this application has a control panel state where the handle 40 or the display panel assembly 20 is not operated. The display panel assembly 20 is flush with the glass door panel 60 and hides the handle 40, effectively preventing accidental opening of the dishwasher door during the washing process and improving safety. In addition, by adopting a display panel assembly 20 structure that can be manually rotated and switched between a first position and a second position, the contradiction between poor viewing angle and uneven appearance when the display interface is fixed is solved. When the user operates the dishwasher, the display panel assembly 20 can be switched to an angle that conforms to the human eye's downward viewing habit, obtaining a better visual and operating experience. After use, it can be reset to a flat state flush with the door panel, perfectly restoring the flatness of the product's appearance.

[0094] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above 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.

[0095] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
