The inclined shape solves the user operation experience problem, but the appearance of the whole machine is uneven and inconsistent with the cabinet. Utility Model Content

[0003] Based on this, it is necessary to provide a door structure and a dishwasher to address the problem that existing dishwashers are difficult to balance the coordination between the whole machine and the cabinet and the operating experience.

[0004] A first aspect of the present application provides a door structure, comprising: an outer frame, a display operation module and a rotating assembly, wherein:

[0005] An outer frame, wherein the outer frame is provided with a first opening;

[0006] The display operation module is rotatably disposed on the outer frame and forms at least a first position and a second position, and the display operation module is disposed opposite to the first opening;

[0007] The rotating assembly includes a driving assembly, a transmission assembly and a torsion spring, wherein the driving assembly is arranged on the outer frame, one end of the transmission assembly is in transmission connection with the driving assembly, and the other end is connected to the display operation module, and one end of the torsion spring is connected to the outer frame, and the other end is connected to the display operation module;

[0008] When the driving component drives the transmission component to rotate forward, the transmission component can drive the display operation module to rotate from the second position to the first position, and the elastic potential energy of the torsion spring increases; when the driving component drives the transmission component to rotate reversely, the torsion spring can drive the display operation module to rotate from the first position to the second position.

[0009] The door structure disclosed in the present application is characterized in that the display operation module can rotate back and forth between the first position and the second position under the cooperation of the driving component, the transmission component and the torsion spring, so as to realize the switching back and forth between the screen-on state and the screen-off state of the display operation module. When the display operation module is in the second position, the display operation module and the outer frame have a certain angle, which is convenient for users to operate the panel and observe; when the display operation module is in the first position, the display operation module and the outer frame maintain the same horizontal plane, solving the problems of the appearance and operation experience of the whole dishwasher and the cabinet. The door structure of the present application is characterized in that the display operation module can rotate according to the usage situation. When the user operates it, the display operation module can rotate to the inclined surface for the convenience of the user. After the operation is completed, the display operation module can automatically return to the screen state, ensuring the appearance of the whole machine and the cabinet; the display operation module is opened and closed by the movement of the connecting rod and the swing arm and the torsion spring scheme of the rotating shaft, which has a simple structure, stable transmission and low cost.

[0010] In one embodiment, the driving assembly includes a driving motor, the transmission assembly includes a transmission rod and a rocker arm, the driving motor, the transmission rod and the rocker arm are sequentially connected in transmission, and the rocker arm abuts against the back side of the display operation module.

[0011] The door body structure in the above embodiment further defines that the transmission rod can rotate with the rotation shaft of the driving motor, and the transmission rod can be connected to the rocker arm in terms of transmission, and abut against the back of the display operation module through the swing arm, so that the rocker arm can be hidden in the space enclosed by the front frame and the rear cover, and will not affect the overall appearance of the door body structure. At the same time, the rocker arm is connected to the display operation module by abutment. When the transmission assembly rotates forward, the transmission assembly can gradually disengage from the abutment with the display operation module, so that the torsion spring can drive the display operation module to rotate from the first position to the second position.

[0012] In one embodiment, the driving assembly also includes a reduction assembly, which includes a first gear, a second gear and a third gear, the first gear is transmission-connected to the rotating shaft of the driving motor, the third gear is transmission-connected to the transmission rod, the first gear and the third gear are coaxially arranged, and the second gear is respectively meshed with the first gear and the third gear.

Through the cooperation of the first gear, the second gear and the third gear, not only can the torque on the transmission rod be increased, thereby increasing the force of the rocker arm on the display operation module, but also the rotation speed of the transmission rod is reduced, thereby preventing the rocker arm from driving the display operation module to rotate rapidly, thereby increasing the risk of damage to the display operation module due to large rotational inertia.

[0014] In one embodiment, the number of the rocker rods is two, and the two rocker rods are spaced apart and distributed at both ends of the transmission rod.

[0015] The door structure in the above embodiment further defines that the two swing rods are spaced apart and distributed at both ends of the transmission rod, so as to avoid the force of the swing rod on the display operation module being too concentrated at one point, thereby ensuring that the display operation module remains stable during the rotation process.

[0016] In one embodiment, the door structure also includes a first micro switch, which is electrically connected to the drive motor. The first micro switch is arranged on the outer frame, and a first protrusion is formed on the surface of the rocker arm. When the rocker arm drives the display operation module to rotate to the first position, the first protrusion presses the contact of the first micro switch, and the drive motor stops working.

[0017] The door body structure in the above embodiment further defines a first micro switch that is arranged on the outer frame and is linked to the drive motor. When the drive motor reverses and the rocker arm rotates from the second position to the first position, the first protrusion on the rocker arm presses the contact on the first micro switch, and the first micro switch outputs a control signal to the drive motor to control the drive motor to stop working. The display operation module remains in the second position until the drive motor receives a forward rotation signal and the rocker arm breaks free from the contact with the display operation module.

[0019] The door body structure in the above embodiment further defines a second microswitch that is linked to the drive motor and is arranged on the outer frame. When the drive motor reverses and the rocker arm rotates from the first position to the second position, the second protrusion on the transmission rod presses the contact on the second microswitch, and the second microswitch outputs a control signal to the drive motor to control the drive motor to stop working. The display operation module remains in the first position until the drive motor receives the reversal signal and the rocker arm is in close contact with the display operation module.

[0020] In one embodiment, a support portion is provided on the outer frame, a first semicircular groove is formed on the support portion, a fixed pressure plate is provided on the support portion, a second semicircular groove matching the first semicircular groove is formed on the fixed pressure plate, and the fixed sleeve is at least partially clamped between the first semicircular groove and the second semicircular groove.

[0022] In one embodiment, the bottom of the back side of the display operation module is rotatably connected to the outer frame. When the display operation module is in the first position, the front side of the display operation module is flush or horizontal with the front side of the outer frame. The connection between the transmission assembly and the display operation module is located at the top or both sides of the back side of the display operation module.

[0023] The door structure in the above embodiment further defines that when the display operation module is in the first position, the front of the display operation module is flush with the front of the outer frame, and when the door structure is in the screen-off state, the front of the outer frame is flat; based on the fact that the connection between the transmission assembly and the display operation module is located at the top or both sides of the back of the display operation module, when the rocker arm pushes the display operation module to rotate, the display operation module will not pass through the first opening.

[0024] In one of the embodiments, a mounting seat is provided on the outer frame below the first opening, and two arc-shaped grooves are formed on the mounting seat at intervals.

[0040] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0041] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so as to describe the embodiments of the present application described herein.

[0042] like Figures 1 to 7 As shown, this embodiment provides a door structure, including:

[0043] An outer frame 100, wherein the outer frame 100 is provided with a first opening 101;

[0044] A display operation module 200, which is rotatably disposed on the outer frame 100 and forms at least a first position and a second position, and the display operation module 200 is disposed opposite to the first opening 101;

[0045] The rotating assembly 300 includes a driving assembly 310, a transmission assembly 320 and a torsion spring 330. The driving assembly 310 is disposed on the outer frame 100. One end of the transmission assembly 320 is connected to the driving assembly 310 in a transmission manner, and the other end is connected to the display operation module 200. One end of the torsion spring 330 is connected to the outer frame 100, and the other end is connected to the display operation module 200.

[0046] When the driving component 310 drives the transmission component 320 to rotate forward, the transmission component 320 can drive the display operation module 200 to rotate from the second position to the first position, and the elastic potential energy of the torsion spring 330 increases; when the driving component 310 drives the transmission component 320 to rotate reversely, the torsion spring 330 can drive the display operation module 200 to rotate from the first position to the second position.

[0047] The outer frame 100 may be, but is not limited to, a metal shell or a non-metal shell. For example, the outer frame 100 may be a plastic shell. The overall shape of the outer frame 100 is a rectangular block. The outer frame 100 may be formed by a front frame 110 and a rear cover 120.

[0048] The display operation module 200 can be used to display the working status information of the electronic device and receive the user's command information. For example, the display operation module 200 of the present application is electrically connected to the dishwasher body. The display operation module 200 can display the current working status information of the dishwasher, such as washing time, drying temperature, working mode, etc. The display operation module 200 can also receive the user's command information through methods such as buttons, touch screens, voice, etc. to drive the dishwasher to operate in a user-specified manner. At the same time, the display operation module 200 can rotate relative to the outer frame 100, and the display operation module 200 and the outer frame 100 form a certain angle at the first opening 101, which can avoid the situation where the user needs to squat to operate the display operation module 200 when the device such as the dishwasher is embedded and the installation height is low.

[0049] The driving assembly 310 can provide power to drive the transmission assembly 320 to rotate relative to the outer frame 100. The transmission assembly 320 can be connected to the actual operation module by abutting against the display operation module 200. The driving assembly 310 can drive the transmission assembly 320 to rotate forward or reverse. When the transmission assembly 320 rotates forward, the transmission assembly 320 abuts against the display operation module 200 and drives the display operation module 200 to rotate from the second position to the first position. The display operation module 200 is located in the first position, that is, the screen-off state, and the display operation module 200 and the outer frame 100 maintain a uniform horizontal plane; when the transmission assembly 320 reverses, the transmission assembly 320 gradually disengages from the abutment with the display operation module 200.

[0050] The torsion spring 330 can use elastic potential energy to drive the display operation module 200 to rotate from the first position to the second position, that is, the screen-opening state. The display operation module 200 has a certain angle with the outer frame 100. Specifically, when the display operation module 200 is in the first position, the torsion spring 330 is in a compressed state to generate elastic potential energy. When the transmission assembly 320 is reversed, the transmission assembly 320 gradually disengages from the abutment with the display operation module 200, and the torsion spring 330 applies a force to the display operation module 200, and causes the display operation module 200 to rotate from the first position to the second position. It should be noted that in some embodiments, the outer frame 100 and the display operation module 200 are respectively provided with hanging holes, and hooks are formed at both ends of the torsion spring 330. The two ends of the torsion spring 330 can be connected by hooking with the hanging holes on the outer frame 100 and the hanging holes on the display operation module 200 through the hooks.

[0051] In the above-mentioned embodiments, the outer frame 100 is provided with a first opening 101; the display operation module 200 is rotatably arranged on the outer frame 100 and forms at least a first position and a second position, and the display operation module 200 is arranged opposite to the first opening 101; one end of the transmission component 320 is transmission-connected to the driving component 310, and the other end is connected to the display operation module 200; one end of the torsion spring 330 is connected to the outer frame 100, and the other end is connected to the display operation module 200; the display operation module 200 can rotate back and forth between the first position and the second position with the cooperation of the driving component 310, the transmission component 320 and the torsion spring 330, so as to realize the display operation module 200 switching back and forth between the on-screen state and the off-screen state; when the display operation module 200 is in the second position, the display operation module 200 and the outer frame 100 have a certain angle, which is convenient for the user to operate the panel and observe; when the display operation module 200 is in the first position, the display operation module 200 and the outer frame 100 maintain a uniform horizontal plane, solving the appearance and operation experience problems of the dishwasher and the cabinet. The door structure of the present application is characterized in that the display operation module 200 can be rotated according to the usage situation. When the user is operating it, the display operation module 200 can be rotated to an inclined surface for the convenience of the user. After the operation is completed, the display operation module 200 can automatically return to the screen state, thereby ensuring the appearance of the whole machine and the cabinet. The display operation module 200 is rotated and opened and closed by moving the connecting rod rocker arm 322 and cooperating with the rotating shaft torsion spring 330. The structure is simple, the transmission is stable, and the cost is low.

[0052] like Figure 2 and Figure 6 , Figure 8 As shown, in addition to the features of the above embodiments, this embodiment further defines: the driving component 310 includes a driving motor 311, the transmission component 320 includes a transmission rod 321 and a rocker bar 322, the driving motor 311, the transmission rod 321 and the rocker bar 322 are connected in sequence, and the rocker bar 322 abuts against the back of the display operation module 200.

[0053] Among them, the transmission rod 321 can rotate with the rotation shaft of the driving motor 311, and the transmission rod 321 can be connected to the rocker arm 322 in transmission. For example, a through hole is provided on the rocker arm 322, and the transmission rod 321 can pass through the through hole. The shape of the through hole can be engaged with the transmission rod 321, so that when the transmission rod 321 rotates, it can drive the rocker arm 322 to rotate; through the swing arm abutting against the back side of the display operation module 200, the rocker arm 322 can be hidden in the space enclosed by the front frame 110 and the rear cover 120, and will not affect the overall appearance of the door body structure. At the same time, the rocker arm 322 is connected to the display operation module 200 by abutting. When the transmission assembly 320 rotates forward, the transmission assembly 320 can gradually disengage from the abutment with the display operation module 200, so that the torsion spring 330 can drive the display operation module 200 to rotate from the second position to the first position.

[0054] like Figure 8 As shown, in addition to the features of the above-mentioned embodiments, this embodiment further defines: the driving component 310 also includes a reduction assembly 312, the reduction assembly 312 includes a first gear 3121, a second gear 3122 and a third gear 3123, the first gear 3121 is transmission-connected to the rotating shaft of the driving motor 311, the third gear 3123 is transmission-connected to the transmission rod 321, the first gear 3121 and the third gear 3123 are coaxially arranged, and the second gear 3122 is respectively meshed with the first gear 3121 and the third gear 3123.

[0055] The transmission rod 321 is connected to the driving motor 311 through the deceleration assembly 312, wherein the deceleration assembly 312 is composed of at least a first gear 3121, a second gear 3122 and a third gear 3123, and the rotating shaft of the driving motor 311, the first gear 3121, the second gear 3122, the third gear 3123 and the transmission rod 321 are sequentially connected. Through the cooperation of the first gear 3121, the second gear 3122 and the third gear 3123, not only can the torque on the transmission rod 321 be increased, thereby increasing the force of the swing rod 322 on the display operation module 200, but also the rotation speed of the transmission rod 321 is reduced, so as to avoid the swing rod 322 driving the display operation module 200 to rotate quickly, thereby increasing the risk of damage to the display operation module 200 due to large rotation inertia. It should be noted that in other embodiments, the deceleration assembly 312 also includes a fourth gear, a fifth gear, etc., so as to increase the torque of the transmission rod 321 and reduce the rotation speed of the transmission rod 321.

[0056] like Figure 2 and Figure 6 As shown, in addition to the features of the above embodiments, this embodiment further defines that: the number of the rocker rods 322 is two, and the two rocker rods 322 are spaced apart and distributed at both ends of the transmission rod 321 .

[0057] The two swing rods 322 are spaced apart at both ends of the transmission rod 321 to prevent the force of the swing rod 322 on the display operation module 200 from being too concentrated, and to ensure that the display operation module 200 remains stable during the rotation process. It should be noted that in other embodiments, the number of the swing rods 322 may also be one or more. If the number of the swing rods 322 is more than one, the plurality of swing rods 322 should be spaced apart on the transmission rod 321.

[0058] like Figure 3 and Figure 4As shown, in addition to the features of the above embodiments, this embodiment further defines: the door structure also includes a first micro switch 400, the first micro switch 400 is electrically connected to the drive motor 311, the first micro switch 400 is arranged on the outer frame 100, and a first protrusion 3221 is formed on the surface of the rocker arm 322. When the rocker arm 322 drives the display operation module 200 to rotate to the first position, the first protrusion 3221 presses the contact of the first micro switch 400, and the drive motor 311 stops working.

[0059] Among them, a first micro switch 400 linked to the drive motor 311 is provided on the outer frame 100. When the drive motor 311 reverses and the rocker arm 322 rotates from the second position to the first position, the first protrusion 3221 on the rocker arm 322 presses the contact on the first micro switch 400, and the first micro switch 400 outputs a control signal to the drive motor 311 to control the drive motor 311 to stop working, and the display operation module 200 remains in the second position until the drive motor 311 receives a forward rotation signal and the rocker arm 322 breaks away from the abutment with the display operation module 200.

[0060] like Figure 2 and Figure 6 As shown, in addition to the features of the above-mentioned embodiments, the present embodiment further defines: the door structure also includes a second micro switch 500, the second micro switch 500 is electrically connected to the drive motor 311, and the second micro switch 500 is arranged on the outer frame 100; one end of the transmission rod 321 is transmission-connected to the drive motor 311, and the other end is sleeved with a fixed shaft sleeve 323, the fixed shaft sleeve 323 is rotatably arranged on the outer frame 100, and the fixed shaft sleeve 323 is formed with a second protrusion 3231, and when the rocker arm 322 drives the display operation module 200 to rotate to the second position, the second protrusion 3231 presses the contact of the second micro switch 500, and the drive motor 311 stops working.

[0061] Among them, a second micro switch 500 linked to the drive motor 311 is provided on the outer frame 100. When the drive motor 311 reverses and the rocker arm 322 rotates from the first position to the second position, the second protrusion 3231 on the transmission rod 321 presses the contact on the second micro switch 500, and the second micro switch 500 outputs a control signal to the drive motor 311 to control the drive motor 311 to stop working. The display operation module 200 remains in the first position until the drive motor 311 receives the reverse signal, and the rocker arm 322 is in close contact with the display operation module 200.

[0067] Among them, the display operation module 200 and the outer frame 100 are rotatably connected through the cooperation of the rotating column 211 and the arc-shaped groove 103. Specifically, the shape of the arc-shaped groove 103 is adapted to the shape of the rotating column 211. During the assembly of the rotating column 211 and the mounting seat, the rotating column 211 can be inserted into the arc-shaped groove 103.
