[0073] Example 1

[0074] like Figures 1-4 As shown, this embodiment provides a door mechanism applicable to household appliances such as dishwashers and disinfection cabinets. The door mechanism includes a door body 1 and a control device 2 mounted on the door body 1. The household appliance includes a body with a front opening, and the door mechanism is located at the front opening. The door body 1 can selectively open or close the front opening, and the control device 2 is used to control the operation of the household appliance. In other words, the door mechanism can open or close the internal opening of the household appliance while simultaneously enabling touch control of the appliance.

[0075] The embodiment takes the door mechanism applied to the dishwasher as an example to introduce the specific structure of the door mechanism. It can be understood that the type of the household appliance and the specific structure of the machine body will not limit and change the installation structure of the control device 2 and the control device 2 on the door body 1, that is, the application of the door mechanism on other household appliances can refer to the application of the door mechanism on the dishwasher.

[0076] It is worth noting that the door body 1 in the embodiment can be hinged to the machine body or can be pullably arranged on the machine body. The present application does not limit the specific connection form of the door body 1 and the machine body. At the same time, the front, back, left, right and other directions referred to in the following are all with reference to the orientation of the household appliance relative to the user when in use, that is, the front side refers to the side facing the user, the back side refers to the side away from the user, and the left and right directions refer to the side from the user's left hand to the right hand.

[0077] In the embodiment, the door body 1 has a front-side opening mounting groove 118, and the control device 2 includes a shell 21 and a control screen 22 arranged on the top of the shell 21. The shell 21 is movably connected with the door body 1 to switch the control device 2 between the first state and the second state. When the control device 2 is in the first state, the control screen 22 is hidden in the mounting groove 118 and the front side of the shell 21 is flush with the front side of the door body 1. When the control device 2 is in the second state, the control screen 22 is exposed outside the mounting groove 118.

[0078] The door mechanism provided in the embodiment can switch the control device 2 to the first state when the control device 2 is not needed, so that the control screen 22 of the control device 2 is hidden in the mounting groove 118, avoiding the control screen 118 being exposed, thereby reducing the probability of the control screen 22 being damaged due to collision with external objects during the transportation or use of the door mechanism and the household appliance, and also reducing the probability of oil stains entering the inside of the control screen 22 when cleaning the outer surface of the door mechanism, improving the use safety and reliability of the control screen 22 and the control device 2. When the control screen 22 is needed, the control screen 22 is exposed outside the mounting groove 118, so that the control screen 22 can be located within the user's field of view for operation, improving the convenience and comfort of user operation.

[0079] Preferably, when the control device 2 is in the first state, the front side of the shell 21 is flush with the front side of the door body 1, thereby ensuring the appearance flatness of the door mechanism when not in use, and improving the convenience of cleaning the door mechanism.

[0080] The specific structure of the control device 2 can refer to the existing arrangement, and the embodiment does not limit and elaborate on this.

[0081] In the embodiment, the operating device 2 is rotationally connected with the door body 1, so that the operating device 2 is rotationally switched between the first state and the second state. When the operating device 2 is in the first state, the operating device 2 is vertically arranged in the mounting groove 118. When the operating device 2 is in the second state, the operating device 2 is arranged to be inclined relative to the door body 1, and the upper end of the operating device 2 extends out of the mounting groove 118.

[0082] In order to reduce the space required for the rotation of the operating device 2, the middle part of the shell 21 in the height direction is rotationally connected with the door body 1. Thus, when the operating device 2 is flipped from the first state to the second state, the upper end of the operating device 2 is flipped forward to rotate out of the mounting groove 118, and the lower end of the operating device 2 is flipped backward to be deeply arranged in the mounting groove 118, so that the lower part of the mounting groove 118 is exposed, and other structures are conveniently arranged. In other embodiments, the lower end of the shell 21 can be rotationally connected with the left and right groove walls of the mounting groove 118.

[0083] In order to facilitate the opening and closing of the door body 1, in the embodiment, the lower side of the mounting groove 118 is formed with a handhold structure, and a user can apply a pushing force or a pulling force to the door body 1 through the handhold structure, so as to realize the opening and closing of the door body 1.

[0084] By forming the handhold structure in the mounting groove 118, when the handhold structure is not needed, the operating device 2 can be arranged in the first state, so that the handhold structure is hidden in the mounting groove 118, and the outer surface of the door mechanism is flat, the appearance of the door mechanism is improved, and the outer surface of the door mechanism is conveniently cleaned. When the handhold structure is needed to open and close the door mechanism, the operating device 2 can be rotated to the second state, so that the user can operate the door body 1 through the handhold structure, the door body 1 is opened or closed, and the operation convenience of the door body 1 is ensured. At the same time, since the handhold structure does not occupy the space of the outer surface of the door body, the arrangement of the handhold structure does not interfere with the arrangement of the operating device 2 on the door body, the probability of interference between the handhold structure and the operating device 2 is reduced, and the layout rationality of the operating device 2 is improved.

[0085] In the embodiment, the handhold structure is arranged in the mounting groove 118, which is also beneficial to increase the area of the handhold structure, improve the operation comfort of the user, and be more in line with the habits of the user in opening and closing the door. In other embodiments, the handhold structure can be arranged on the left side and / or the right side of the mounting groove 118.

[0086] In the embodiment, the handhold structure includes a handhold groove with an upward opening, and a user can stretch a hand into the handhold groove to grasp the structure between the front groove wall of the handhold groove and the front surface of the door body, so as to apply a force to the door body 1 to open or close the door body 1. Preferably, the handhold groove extends in the left-right direction, and the two ends extend to the left and right sides of the front opening, so as to increase the length of the handhold groove and reduce the limitation on the operation position of the user.

[0087] Furthermore, the bottom of the mounting groove 118 is lower than the lower edge of the front opening, forming a handle groove between the mounting groove 118 and the lower edge of the front opening. This arrangement simplifies the formation of the handle groove, thereby simplifying the structure of the door body 1 and reducing the processing and assembly difficulty of the door body 1.

[0088] like Figures 4-6 As shown, the door body 1 includes an outer frame 11 and an inner liner 12. The outer frame 11 is made of metal to ensure the structural strength and rigidity of the entire door body 1, and the front side of the outer frame 11 can be processed by polishing or other methods to form the outer appearance surface. The inner liner 12 is connected to the rear side of the outer frame 11 and is made of elastic materials such as rubber to prevent the door body 1 from hard collision with the machine body, while enhancing the sealing between the door body 1 and the machine body.

[0089] The mounting groove 118 is formed on the outer frame 11, and the housing 21 of the control device 2 is rotatably connected to the outer frame 11 to improve the connection convenience between the control device 2 and the outer frame 11 and the installation reliability of the control device 2 on the door body 1.

[0090] The outer frame 11 includes a vertically arranged front door panel 111. The front door panel 111 has a rectangular structure, and its four sides are all bent backward vertically to form folding plates 112 to enhance the overall structural strength and rigidity of the entire outer frame 11. The aforementioned front opening is formed on the front door panel 111. A stiffening plate portion 116 connects the front door panel 111 to each folding plate 112, and multiple stiffening plates 116 on each folding plate 112 are spaced apart along the corresponding length direction of the folding plate 112.

[0091] For ease of description, the top folding plate 112 is referred to as the top folding plate 112a, and the two side folding plates 112 are referred to as the side folding plates 112b.

[0092] To improve the ease of installation of the control device 2 on the outer frame 11, the outer frame 11 also includes two mounting plates 113 that are opposite to each other and spaced apart in the left-right direction. The aforementioned mounting groove 118 is formed between the two mounting plates 113. The two sides of the control device 2 are rotatably connected to the two mounting plates 113 via rotating shafts 5. The front side of the mounting plate 113 is connected to the front door panel 111. The two mounting plates 113 are opposite to and spaced apart from the adjacent side flaps 112b.

[0093] To ensure the structural strength and rigidity of the mounting plate portion 113, a connecting plate portion 115 is connected between the two side flaps 112b. The lower ends of both mounting plate portions 113 are perpendicularly connected to the connecting plate portion 115, and the upper surface of the connecting plate portion 115 forms the lower bottom of the mounting groove 118. The connecting plate portion 115 is lower than the lower edge of the front opening.

[0094] Preferably, a rib plate part 116 is connected between the connecting plate part 115 and the front door plate 111, a plurality of rib plate parts 116 are arranged in the left-right direction and all of the rib plate parts 116 are located between the mounting plate part 113 and the adjacent side turning plate 112b, so as to avoid the rib plate part 116 being arranged in the mounting groove 118 and scratching the user's hand.

[0095] The outer frame 11 further comprises a top plate part 117 connected to the back of the front door plate 111, the top plate part 117 is arranged opposite and spaced apart from the connecting plate part 115, and the upper end of the mounting plate part 113 is connected to the top plate part 117. The top plate part 117, the connecting plate part 115 and the two mounting plate parts 113 jointly form the mounting groove 118.

[0096] In order to avoid the groove wall of the mounting groove 118 scratching the operation screen 22 during the rotation of the operation device 2, the upper side groove wall of the mounting groove 118 is preferably an arc-shaped structure with the opening facing downward, so as to provide a clearance for the rotation of the upper end of the operation device 2. In the embodiment, preferably, the top plate part 117 is an arc-shaped plate with the opening facing downward, so as to simplify the processing of the top plate part 117.

[0097] Further, the outer frame 11 further comprises a rear limiting plate part 114 arranged opposite and spaced apart from the front door plate 111, the upper end of the rear limiting plate part 114 is connected to the top plate part 117, and the left and right sides thereof are respectively connected to the two mounting plate parts 113, the lower side of the rear limiting plate part 114 is spaced apart from the connecting plate part 115, so that the rear limiting plate part 114 and the connecting plate part 115 form a rear opening 110. When the operation device 2 is in the first state, the rear side of the outer shell 21 abuts against the rear limiting plate part 114, and when the operation device 2 is in the second state, the lower end of the outer shell 21 passes through the rear opening. The arrangement of the rear limiting plate part 114 can realize the installation limiting of the operation device 2 and improve the installation reliability of the operation device 2, and the arrangement of the rear opening 110 can also avoid the interference of the rear limiting plate part 114 with the rotation of the operation device 2; at the same time, the arrangement of the rear opening 110 also facilitates the wiring of the connecting wires of the operation device 2.

[0098] As shown in Figure 6 and Figure 7 In order to improve the reliability of the rotation of the operation device 2, one of the operation device 2 and the groove wall of the mounting groove 118 is provided with a guide sliding groove 1131, and the other is provided with a guide piece 6, the guide piece 6 is slidingly arranged in the guide sliding groove 1131, and the guide sliding groove 1131 extends along the movement direction of the operation device 2. By arranging the guide piece 6 and the guide sliding groove 1131, the movement of the operation device 2 can be guided, and the reliability of the switching of the operation device 2 between the first state and the second state is ensured; at the same time, the two ends of the guide sliding groove 1131 are also beneficial to limit the stroke of the movement of the operation device 2 and avoid the overtravel of the operation device 2.

[0099] In the embodiment, the guide chute 1131 is an arc-shaped chute, and the center of the arc-shaped chute 1131 is located on the rotation axis of the control device 2. Thus, the rotation of the control device 2 can be guided by the cooperation of the guide chute 1131 and the guide piece 6, and the rotation reliability of the control device 2 is improved. Meanwhile, the rotation angle of the control device 2 can be limited by the two ends of the guide chute 1131, so that the control device 2 is prevented from rotating to a position interfering with or colliding with other structures.

[0100] The guide chute 1131 is preferably arranged on the lower part of the mounting plate 113 and below the rotation shaft 5, so that the length of the guide chute 1131 is increased when the turning angle of the control device 2 is fixed, and the guiding reliability and smoothness are improved.

[0101] When the control device 2 is in the first state, the guide piece 6 is located at the front end of the guide chute 1131 and abuts against the front end slot wall, so that the control device 2 is prevented from rotating to the front side of the convex door body 1. When the control device 2 is in the second state, the guide piece 6 is preferably located at the rear end of the guide chute 1131 and abuts against the rear end slot wall, so that the turning angle of the control device 2 is limited.

[0102] Preferably, the corresponding central angle of the guide chute 1131 is less than 60°, so that the problem of increasing the thickness requirement of the door body 1 due to the large rotation range of the control device 2 is avoided, and the structural compactness is improved.

[0103] In the embodiment, the guide chute 1131 is arranged on the mounting plate 113, and the guide piece 6 is protruded on the shell 21 of the control device 2. In other embodiments, the guide chute 1131 can be arranged on the shell 21 of the control device 2, and the guide piece 6 can be protruded on the mounting plate 113.

[0104] Preferably, the guide chute 1131 is arranged on both mounting plates 113, and the guide piece 6 is arranged on both sides of the control device 2, so that the force stability of both ends of the control device 2 is improved, and the rotation smoothness of the control device 2 is improved.

[0105] The door mechanism further comprises an elastic reset piece 7, which is used to keep or restore the control device 2 to the first state. Since the door mechanism is in a non-use state most of the time, the arrangement of the elastic reset piece 7 is beneficial to stably keeping the control device 2 in the first state, and is beneficial to preventing the control device 2 from turning relative to the door body 1 under the action of slight external force or vibration, so that the state stability of the door mechanism is improved; and the arrangement of the elastic reset piece 7 is also beneficial to automatically restoring the control device 2 from the second state to the first state.

[0106] That is, in the present embodiment, when the operating device 2 is in the first state, the user can push the operating device 2 to overturn by applying a backward pressing force to the operating device 2 until the operating device 2 is overturned to the second state; when the user removes the force applied to the operating device 2, the operating device 2 is automatically reset under the elastic restoring force of the elastic reset member 7, improving the automaticity of the reset of the operating device 2.

[0107] In the present embodiment, the elastic reset member 7 is a tension spring, the front end of the tension spring is fixed relative to the door body 1, and the rear end of the tension spring is fixed relative to the operating device 2; when the operating device 2 is in the second state, the tension spring is in a lengthened state, thereby applying an elastic restoring force to the operating device 2 to move it forward, thereby facilitating the reset of the operating device 2.

[0108] In other embodiments, the elastic reset member 7 can also be a compression spring, that is, the front end of the compression spring is connected with the operating device 2, and the rear end of the compression spring is fixed with the door body 1; when the operating device 2 is in the second state, the compression spring is in a compressed state. In still another embodiment, the elastic reset member 7 can also be a torsion spring, the torsion spring is sleeved on the rotating shaft 5, and one end of the torsion spring is fixed relative to the door body 1, and the other end of the torsion spring is fixed relative to the operating device 2.

[0109] In order to reduce the interference between structures, the elastic reset member 7 is preferably arranged on the outer side of the mounting plate part 113 (i.e. the side of the mounting plate part 113 away from the other mounting plate part 113), the guide sliding groove 1131 penetrates the mounting plate part 113, and the guide member 6 extends outwardly from the mounting plate part 113, and one end of the elastic reset member 7 is connected with the guide member 6. Thus, when the guide member 6 slides along the guide sliding groove 1131, the guide member 6 drives the first end of the elastic reset member 7 to move. This structure of the elastic reset member 7 can avoid the contact between the elastic reset member 7 and the operating device 2, improve the service life of the elastic reset member 7, and reduce the probability of wear of the operating device 2.

[0110] The two mounting plate parts 113 are each provided with an elastic reset member 7 on the side opposite to each other, so as to improve the force balance of the two sides of the operating device 2 and ensure the smooth reset of the operating device 2.

[0111] In order to improve the convenience of the connection between the guide member 6 and the elastic reset member 7, the guide member 6 comprises a sliding part 61 and a hanging ring part 63 which are connected perpendicularly, the sliding part 61 is slidably arranged in the guide sliding groove 1131, and the two ends of the sliding part 61 are respectively connected with the hanging ring part 63 and the housing 21 of the operating device 2. The hanging ring part 63 is located on the outer side of the mounting plate part 113, both ends of the elastic reset member 7 are provided with hooks, and the hook of the first end is hooked on the hanging ring part 63, so as to improve the convenience of the connection between the guide member 6 and the elastic reset member 7.

[0112] The sliding part 61 is preferably cylindrical to reduce edges and reduce the rubbing between the guide sliding groove 1131 and the sliding part 61. Both ends of the guide sliding groove 1131 are circular arcs, and the corresponding diameters of the circular arcs are equal to the diameter of the sliding part 61, so that when the sliding part 61 slides to both ends of the guide sliding groove 1131, the sliding part 61 can stably contact the groove walls at both ends of the guide sliding groove 1131.

[0113] To improve the convenience of connecting the elastic return member 7 and the door body 1, the back side of the front door panel 111 is provided with a hook portion 119, and the hook of the second end of the elastic return member 7 is hung on the hook portion 119.

[0114] Embodiment Two

[0115] The door mechanism and the household appliance provided in the embodiment have the same basic structure as those in Embodiment One, and only the partial arrangement is different. The same structure as that in Embodiment One will not be described again.

[0116] In the embodiment, the shell of the control device is arranged in the mounting groove and can slide in the front-rear direction. That is, in the embodiment, the control device is always in a vertical state. When the control device is in the first state, the control device is completely accommodated in the mounting groove, and the front side of the shell is flush with the front side of the door body. When the control device is in the second state, the front part of the control device protrudes from the front side of the mounting groove, so that the control screen is exposed.

[0117] In the embodiment, the guide sliding groove extends horizontally in the front-rear direction, and when the control device is in the first state, the guide member is located at the rear end of the guide sliding groove. When the control device is in the second state, the guide member is located at the front end of the guide sliding groove.

[0118] In the embodiment, when the control device is in the first state, the elastic return member is in a normal state or a first compressed state. When the control device is in the second state, the elastic return member is in a second compressed state. The compression amount of the second compressed state is greater than that of the first compressed state. Thus, when the control device is in the second state, the elastic return member can promote the control device to return rearward.

[0119] In the embodiment, the handgrip structure can be arranged on the shell of the control device. Preferably, the lower side of the shell is provided with the handgrip structure. When the control device is in the second state, the handgrip structure is exposed to the mounting groove.

[0120] Preferably, the handgrip structure is a handgrip groove with an opening downward. The handgrip groove has at least a front groove wall, and the part between the front groove wall and the front side of the shell forms a part for a user to hold. The handgrip groove preferably penetrates through the left and right sides of the shell in the left-right direction, and the handgrip groove can also penetrate through the back side of the shell.

[0121] In the embodiment, the driving assembly can also be arranged to drive the operation device to slide. The driving assembly is preferably arranged outside the mounting plate and connected with the guide member, so as to reduce the interference between the driving assembly and the operation device and reduce the space occupation in the mounting groove. The driving assembly is preferably provided with two, which are respectively arranged on the two mounting plates, so as to improve the driving stability and reliability.

[0122] The driving assembly is preferably a linear motor, and the driving end of the linear motor can be telescoped along the front-rear direction and connected with the guide member. The linear motor can be but is not limited to a push rod motor, a wax motor and the like linear driving structure.

[0123] Embodiment three

[0124] The embodiment provides a door mechanism and a household appliance, and the door mechanism provided by the embodiment is a further improvement based on the door mechanism in the embodiment one. The same structure as the embodiment one will not be described herein.

[0125] As shown in Figure 8 and Figure 9 In the embodiment, the door mechanism further comprises a lock assembly 4. The lock assembly 4 has a locking state and an unlocking state, and is used to lock the relative position of the operation device 2 and the door body 1 when the operation device 2 is rotated to the second state.

[0126] By arranging the lock assembly 4, the operation device 2 can be kept in the second state, so as to avoid the trend of the operation device 2 turning back to the first state when the user's hand is inserted into the mounting groove 118, thereby avoiding the squeezing of the user's hand and reducing the probability of interference between the operation device 2 and the user's hand, and improving the user's operation comfort. Meanwhile, keeping the operation device 2 in the second state is also conducive to the user's touch operation on the operation device 2 when the operation device 2 is in the second state, thereby further improving the operation convenience of the operation device 2.

[0127] The lock assembly 4 is a press-type self-locking switch. The lock assembly 4 comprises a lock body 41 and a lock tongue 42. The lock body 41 is provided with a lock groove 4111. One of the lock body 41 and the lock tongue 42 is fixedly arranged on the door body 1, and the other of the lock body 41 and the lock tongue 42 is arranged on the operation device 2. The lock assembly 4 is configured such that the lock tongue 42 can be pressed and inserted into the lock groove 4111 to make the lock assembly 4 in the locking state, and the lock tongue 42 can be pressed out of the lock groove 4111 when the lock assembly 4 is in the locking state.

[0128] That is, when the operation device 2 is rotated to the second state, the lock tongue 42 is pressed against the lock body 41 and clamped into the lock groove 4111, and the self-locking switch is in the locking state, that is, the operation device 2 is kept in the second state. When the operation device 2 is pressed again, the lock tongue 42 is pressed out of the lock groove 4111, that is, the self-locking switch is in the unlocking state, and the operation device 2 can be rotated from the second state to the first state.

[0129] By setting the press type self-locking switch, the switching of the lock assembly 4 between the locked state and the unlocked state can be realized by pressing the operating device 2, which is simple to operate and has low success rate without setting a driving structure.

[0130] In other embodiments, the operating device 2 can also be locked in the second state by setting other structural forms of the lock assembly 4, such as setting an electromagnetic lock or other lock assembly structures that can realize mechanical self-locking.

[0131] Exemplarily, as shown in Figure 10 and Figure 11 , the lock body 41 includes a lock shell 415, a sliding block 412 slidingly arranged in the lock shell 415, and a pawl 411 connected to the top end of the sliding block 412. The bottom of the lock shell 415 and the sliding block 412 are connected with a spring 414, and the pawl 411 includes two claw parts that can be relatively opened or closed, and a lock slot 4111 is formed between the two claw parts. The sliding block 412 is hinged with a lock rod 413, and the lock shell 415 is provided with a clamping groove 416. When the lock assembly 4 is in the unlocked state, the pawl 411 is in the open state, and the upper end of the pawl 411 protrudes out of the lock shell 415.

[0132] The lock tongue 4 includes a rod part 422 and a lock head part 421 connected to the end of the rod part 422. When the pawl 411 is in the open state, the lock head part 421 can extend into the lock slot 4111 and press against the pawl 411, so as to make the pawl 411 retract into the lock shell 415, and the two claw parts of the pawl 411 gradually close under the limitation of the cavity wall of the lock shell 415. When the end of the lock rod 413 is clamped into the clamping groove 416, the lock assembly 4 is in the locked state, at this time, the lock head part 411 is limited to be taken out of the lock slot 4111, and the spring 414 is in the compressed state.

[0133] When the lock tongue 42 is pressed again, the lock tongue 42 presses the sliding block 412, so that the lock rod 415 can be taken out of the locked position along the sliding clamping groove 416. After the lock tongue 42 is released, the sliding block 412 is reset under the restoring force of the spring 414, and the pawl 411 is ejected out of the cavity of the lock shell 415, and the two claw parts of the pawl 411 are opened, so that the lock tongue 42 can be taken out of the lock slot 4111.

[0134] It can be understood that the above is an exemplary structure of the lock assembly 4, which can realize the structure of the press locking and self-locking switch that is unlocked by pressing again after locking, which is the prior art, and the structure of the lock assembly 4 will not be described and limited again.

[0135] Preferably, the lock assembly 4 is installed on the outer side of the mounting plate part 113 to reduce the probability of interference between the lock assembly 4 and the operating device 2, improve the use safety and service life of the lock assembly 4. The outer side of each mounting plate part 113 is provided with the lock assembly 4 to improve the force balance of the operating device 2 at both ends, effectively ensuring that the operating device 2 can remain in the second state.

[0136] As shown in Figure 8 and Figure 9 In this embodiment, the lock body 41 is installed on the mounting plate part 113 and located at the rear side of the guide sliding groove 1131, and the lock tongue 42 is connected to the guide piece 6, thereby reducing the force applied to the guide piece 6, reducing the volume requirement of the guide piece 6, avoiding the problem of the guide sliding groove 1131 being too large due to the guide piece 6 being too large, and improving the structural stability; and the lock body 41 is fixedly arranged, and the lock tongue 42 slides with the guide piece 6, which can ensure that the lock tongue 42 is reliably inserted into the lock groove 4111.

[0137] In order to improve the connection convenience of the guide piece 6, the lock tongue 42 and the elastic reset piece 7, the guide piece 6 comprises a connecting part 62 connected perpendicularly to the sliding part 61, the connecting part 62 is located on the outer side of the mounting plate part 113, and is connected with the lock tongue 42. The hanging ring part 63 and the sliding part 62 are arranged on the opposite sides of the connecting part 62. This arrangement can ensure that the lock tongue 42 does not interfere with the mounting plate part 113, and improves the installation reliability of the lock tongue 42.

[0138] Embodiment Four

[0139] The door mechanism and household appliance provided in this embodiment are further improved based on the door mechanism in Embodiment One, and the same structures as in Embodiment One will not be described again.

[0140] As shown in Figure 12 and Figure 13 In this embodiment, the door mechanism further comprises a driving assembly 3, which is drivingly connected with the operating device 2 to drive the operating device 2 to rotate and switch between the first state and the second state. That is, by providing the driving assembly 3, the automatic rotation control of the operating device 2 can be realized, the automation of the rotation of the operating device 2 is improved, the automation degree of the door mechanism is improved, and the operation experience is improved.

[0141] The driving assembly 3 is preferably mounted on the outer side of the mounting plate part 113 (the side of the mounting plate part 113 away from the other mounting plate part 113), and the driving assembly 3 is drivingly connected with the guide 6, so that the driving assembly 3 and the operating device 2 are respectively located on the opposite sides of the mounting plate part 113, reducing the probability of interference between the driving assembly 3 and the operating device 2, and improving the operation safety and reliability of the driving assembly 3. At the same time, mounting the driving assembly 3 on the mounting plate part 113 can simplify the structure of the outer frame 11, reduce the processing difficulty of the outer frame 11, and improve the installation convenience of the driving assembly 3.

[0142] In other embodiments, the driving assembly 3 can also be mounted on the back of the operating device 2 or other suitable positions for mounting the driving assembly 3. In other embodiments, the rotary driving assembly 3 can be mounted on the outer side of the mounting plate part 113 and connected with the rotating shaft 5.

[0143] The driving assembly 3 is preferably provided with two, and the two driving assemblies 3 are respectively mounted on the outer sides of the two mounting plate parts 113, to improve the force balance on the left and right sides of the operating device 2, improve the operation safety and reliability of the operating device 2, and reduce the probability of operation jamming of the operating device 2. In other embodiments, the driving assembly 3 can also be provided with only one, and the side of the operating device 2 without the driving assembly 3 is balanced in force by the sliding of the guide 6 in the guide sliding groove 1131.

[0144] The driving assembly 3 preferably includes a driving motor 31 and a connecting rod unit 32, and the two ends of the connecting rod unit 32 are respectively hinged with the driving shaft of the driving motor 31 and the guide 6, so as to better control the running track of the guide 6 through the structural arrangement of the connecting rod unit 32, ensure that the guide 6 can smoothly and reliably slide along the guide sliding groove 1131, and reduce the probability of sliding jamming of the guide 6 in the guide sliding groove 1131.

[0145] In the present embodiment, the driving motor 31 is preferably a linear motor, and the extension direction of the driving end 311 of the linear motor is vertically arranged, so that the extension of the driving end 311 can drive the connecting rod unit 32 to rotate, thereby driving the guide 6 to slide, and the track control of the connecting rod unit 32 can be simplified. Preferably, the connecting rod unit 32 includes one connecting rod, which can simplify the overall structure of the driving assembly 3, reduce the cost, and reduce the weight of the driving assembly 3.

[0146] The driving motor 31 is preferably mounted above the guide sliding groove 1131, to improve the installation convenience thereof on the mounting plate part 113 and ensure the installation space of the driving motor 31.

[0147] The linear motor can be an existing push rod motor, a wax motor, or any motor capable of linear driving. The structure of the linear motor is not limited in the embodiment. In other embodiments, the driving motor 31 can also be a rotary motor. In this case, the linkage unit 32 can include a plurality of hinged linkages.

[0148] In the embodiment, the door body 1 or the control screen 22 of the control device 2 is provided with a control button. The door mechanism further includes a controller. The control button and the rotary driving assembly 3 are both in communication connection with the controller. When the user presses the control button, the control button sends a signal to the controller. The controller controls the driving assembly 3 to operate according to the received signal, so as to switch the control device 2 between the first state and the second state.

[0149] The control button is preferably arranged on the control screen 22, which is beneficial to simplify the control and the structure of the door mechanism. The control button arranged on the control screen 22 and the circuit arrangement and communication principle of the control button controlling the operation of the driving assembly 2 are prior art, which will not be described in the embodiment.

[0150] The control button can be arranged only one, that is, the control button is triggered once, and then the controller controls the driving assembly 2 to realize the state switching of the control device 3. The state switching can be from the first state to the second state, or from the second state to the first state.

[0151] It can be understood that, in the embodiment, since the driving assembly 3 is used to switch the control device 2 between the first state and the second state, the elastic reset member is no longer arranged in the embodiment.

[0152] Embodiment Five

[0153] The embodiment provides a door mechanism and a household appliance. The door mechanism provided in the embodiment is further improved based on the fourth embodiment, and the same structure as the fourth embodiment will not be described in the embodiment.

[0154] In the embodiment, the door mechanism further includes a controller and a detection device. The detection device and the rotary driving assembly 3 are both in communication connection with the controller. The detection device is used to detect whether the user applies a state switching instruction. The controller controls the rotary driving assembly 3 to operate according to the state switching instruction detected by the detection device, so as to further improve the automation degree of the rotation of the control device 2 and improve the user experience.

[0155] Since the household appliances such as dishwashers and sterilizers are usually installed in the kitchen, the user is more active in the kitchen, and in order to avoid the detection device from misjudging and causing the rotating driving assembly 3 to frequently start and stop, preferably, the door body 1 is provided with a sensing area, and the detection device is used to detect hand information located in the sensing area. When the user's hand is inserted into the sensing area, it is determined that the user applies a state switching instruction, and the controller controls the rotating driving assembly 3 to operate according to the hand information detected by the detection device. Since the user's hand is usually higher than the household appliances such as dishwashers when the user is handling other things in the kitchen, it is difficult to be detected by the detection device. When the detection device detects the user's hand in the sensing area, it usually indicates that the user consciously inserts the hand into the detection area, thereby effectively reducing the probability of misjudgment, improving the control safety and control accuracy, and avoiding power loss caused by frequent starting of the rotating driving assembly 3.

[0156] Further, the detection device is a visual detection device, and the visual detection device identifies user hand image information, so that the detection device only receives a detection signal when the user's hand is placed in the sensing area, thereby effectively reducing the probability of misjudgment of the detection device.

[0157] In another embodiment, the detection device can be a voice recognizer, and the state switching instruction is a voice instruction. The voice recognizer is used to identify the voice instruction of the user, so that when the detection device receives a first user instruction, the rotating driving assembly 3 drives the control device 2 to rotate from the first state to the second state; and when the detection device receives a second user instruction, the rotating driving assembly 3 drives the control device 2 to rotate from the second state to the first state. The first user instruction and the second user instruction can be automatically set in the control system according to the user's user habit, or can be factory-set before the household appliance is shipped. The present application does not limit the setting method of the first user instruction and the second user instruction.

[0158] In another embodiment, the detection device can also be a touch detection device, that is, when the user touches the control screen of the control device 2, it is determined that the user applies a state switching instruction, that is, the state switching instruction is touch information. The detection device receives the touch information, and the controller controls the operation of the rotating driving assembly 3 according to the touch information received by the detection device.

[0159] Embodiment six

[0160] The present embodiment provides a door mechanism and a household appliance, and the door mechanism provided by the present embodiment is a further improvement based on the door mechanism provided by embodiment one. The present embodiment will not repeat the same structure as embodiment one.

[0161] As Figure 14 and Figure 15As shown, in the embodiment, the door mechanism further comprises a driving assembly 3, which is drivingly connected with the operating device 2 to drive the operating device 2 to rotate and switch between the first state and the second state. That is, the embodiment can realize automatic rotation control of the operating device 2 by arranging the driving assembly 3, improve the automation of the rotation of the operating device 2, and improve the automation degree of the door mechanism, thereby improving the operation experience.

[0162] The driving assembly 3 is preferably installed on the outer side of the mounting plate part 113 (the side of the mounting plate part 113 away from the other mounting plate part 113), and the driving assembly 3 is drivingly connected with the guide 6, so that the driving assembly 3 and the operating device 2 are located on opposite sides of the mounting plate part 113, reducing the probability of interference between the driving assembly 3 and the operating device 2, and improving the operation safety and reliability of the driving assembly 3. At the same time, installing the driving assembly 3 on the mounting plate part 113 can simplify the structure of the outer frame 11, reduce the processing difficulty of the outer frame 11, and improve the installation convenience of the driving assembly 3.

[0163] In other embodiments, the driving assembly 3 can also be installed on the back of the operating device 2 or other positions suitable for installing the driving assembly 3.

[0164] The driving assembly 3 comprises an electromagnet 33 and a magnetic attraction piece 34, one of the magnetic attraction piece 34 and the electromagnet 33 is installed on the guide 6, and the other is installed on the mounting plate part 113 and located at the rear side of the guide sliding groove 1131. When the electromagnet is de-energized, the magnetic attraction piece is arranged in front of and behind the electromagnet, and the operating device 2 is in the first state; when the electromagnet is energized, the electromagnet attracts the magnetic attraction piece, so as to actuate the operating device 2 to slide and keep to the second state.

[0165] The driving assembly 3 provided in the embodiment, when the electromagnet 33 is de-energized, the electromagnet 33 and the magnetic attraction piece 34 lack magnetic attraction force, and the operating device 2 is kept to the first state under the action of the elastic restoring force of the elastic reset member 7. When the electromagnet 33 is energized, the magnetic attraction force between the electromagnet 33 and the magnetic attraction piece 34 promotes the electromagnet 33 and the magnetic attraction piece 34 to approach each other, thereby driving the guide 6 to slide along the guide sliding groove 1131, and thereby driving the operating device 2 to rotate to the second state; when the electromagnet 33 is de-energized again, the operating device 2 recovers from the second state to the first state under the action of the elastic restoring force of the elastic reset member 7.

[0166] That is, the driving assembly 3 provided in the embodiment can drive the operating device 2 to rotate from the first state to the second state by the attraction force of the electromagnet 33 to the magnetic attraction piece 34 after the electromagnet 33 is energized; when the electromagnet 33 is de-energized, the magnetic attraction piece 34 lacks the attraction force of the electromagnet 33, so that the operating device 2 recovers and keeps to the first state under the action of the elastic restoring force of the elastic reset member 7.

[0167] The driving structure can be effectively simplified, and the driving cost is reduced. The reset of the control device 2 is realized by the power-off of the electromagnet 33 and the reset of the elastic reset member 7, the driving cost is relatively low, and the automatic degree of the reset is relatively high. Meanwhile, when the magnetic attraction member 34 and the electromagnet 33 are close to each other, the magnetic attraction force of the electromagnet 33 on the magnetic attraction member 34 is increased, and the force of the elastic reset member 7 on the magnetic attraction member 34 is also increased. The magnetic attraction force and the elastic restoring force are opposite to each other, so that the movement of the magnetic attraction member 34 is relatively stable. The problem that the movement speed of the control device 2 is suddenly increased or the impact between the magnetic attraction member 34 and the electromagnet 33 is relatively large can be effectively avoided, and the operation safety and reliability of the driving assembly 3 are improved.

[0168] The magnetic attraction member 34 is connected with the guide member 6, and the electromagnet 33 is fixedly installed on the mounting plate portion 113. Therefore, the electromagnet 33 can be prevented from moving with the guide member 6, so that the power supply wire of the electromagnet 33 is prevented from being pulled, and the operation reliability of the driving assembly 3 is improved. Meanwhile, since the magnetic attraction member 34 is relatively light and the electromagnet is relatively heavy, the connection of the magnetic attraction member 34 and the guide member 6 can effectively reduce the external force on the guide member 6, and the service life of the guide member 6 is improved.

[0169] The magnetic attraction member 34 can be integrally formed with the guide member 6, that is, the guide member 6 is made of a magnetic conductive material such as iron. The connection tightness of the magnetic attraction member 34 and the guide member 6 can be improved, and the magnetic attraction member 34 can be prevented from falling off the guide member 6. In other embodiments, the magnetic attraction member 34 can be fixedly connected with the guide member 6 by welding, or can be detachably connected with the guide member 6 by clamping, interference fitting or other ways.

[0170] The magnetic attraction member 34 is preferably in a plate structure, and the plate structure is perpendicular to the mounting plate portion 113. The contact area of the magnetic attraction member 34 and the electromagnet 33 is increased, and the attraction stability of the electromagnet 33 and the magnetic attraction member 34 is improved.

[0171] In order to control the power-on and power-off time of the electromagnet 33, the door mechanism has a power supply circuit for supplying power to the electromagnet 33. A control button is arranged on the control surface of the control device 2, and the control button is in communication connection with a controller. A user can control the power supply circuit to supply power or cut off power to the electromagnet 33 by pressing the control button.

[0172] It can be understood that the driving assembly provided in the embodiment can also be applied to the door mechanism in the second embodiment, that is, the driving assembly is used to drive the control device in the second embodiment to slide. At this time, the magnetic attraction member 34 is connected to the guide member 6, and the electromagnet 33 is arranged on the front side of the guide sliding groove 1131.

[0173] Embodiment Seven

[0174] The embodiment provides a door mechanism and a household appliance, and the door mechanism provided by the embodiment is further improved based on the sixth embodiment, and the same structure as the sixth embodiment is not described herein again.

[0175] In the embodiment, the door mechanism further comprises a controller and a detection device, the detection device and the driving assembly 3 are in communication connection with the controller, the detection device is used for detecting whether a state switching instruction is applied by a user, and the controller controls the driving assembly 3 to operate according to the state switching instruction detected by the detection device, so as to further improve the automation degree of the rotating of the control device 2 and improve the use experience of the user.

[0176] Specifically, in the embodiment, when the detection device detects the state switching instruction, the controller controls the power supply circuit to supply power to the electromagnet; when the detection device does not detect the state switching instruction, the controller controls the electromagnet to be powered off.

[0177] Since the household appliances such as dishwashers and disinfection cabinets are usually installed in the kitchen, the user is more active in the kitchen, and in order to avoid the detection device from misjudging and causing the driving assembly 3 to frequently start and stop, preferably, an induction area is arranged on the door body 1, the detection device is used for detecting hand information located in the induction area, when the user's hand is inserted into the induction area, it is determined that the user applies the state switching instruction, and the controller controls the driving assembly to operate according to the hand information detected by the detection device.
