[0048] A dishwasher is a device that automatically washes tableware, including bowls, chopsticks, plates, dishes, knives, and forks. Fully automatic dishwashers on the market are categorized as both home and commercial. Home dishwashers are suitable for most households today, replacing handwashing and freeing up hands. They are gradually becoming a standard feature of quality living. Some dishwashers open their doors after washing to allow air to exchange with the inner tank, thereby drying the dishes. However, the dishwasher door does not automatically close after opening, requiring manual closing or remaining open. Leaving the door open for extended periods can easily allow pests such as rats and cockroaches to enter the inner tank and contaminate the bowl basket and bowls, significantly impacting the user experience.

[0049] To this end, the present invention proposes a dishwasher that can automatically open and close the door to improve user experience.

[0050] Figure 1 Schematic diagram of the three-dimensional structure of a dishwasher according to some embodiments of the present invention, wherein the door 200 is in an open state. Figure 2 for Figure 1 A partial enlarged schematic diagram of the middle A. Figure 1 and Figure 2 , an embodiment of the present invention proposes a dishwasher, which includes a housing 100, a door body 200 and a drive assembly 300. The housing 100 can be an inner tank, which is roughly in the shape of a rectangular parallelepiped and has an inner cavity inside, in which a cleaning assembly is installed. The inner cavity is provided with an opening 110, through which the user can put tableware and items to be cleaned into the inner cavity for cleaning. The housing 100 is provided with a first locking member 120 for locking the door body 200, and the first locking member 120 is located on the periphery of the opening 110. The door body 200 is rotatably connected to the lower end of the housing 100. For example, the door body 200 can be connected to the housing 100 by a hinge assembly 230, so that the door body 200 can rotate relative to the housing 100, so that the opening 110 of the housing 100 can be opened or closed by rotating the door body 200. The door body 200 is provided with a first connecting member 210 and a second locking member 220. The second locking member 220 can cooperate with the first locking member 120 to lock the door body 200 to the box body 100, thereby closing the opening 110 of the box body 100. The driving assembly 300 is provided with a second connecting member 320. The driving assembly 300 can drive the door body 200 to open or close the opening 110 through the cooperation of the second connecting member 320 and the first connecting member 210. Specifically, the first connecting member 210 and / or the second connecting member 320 can be magnets, so that the first connecting member 210 and the second connecting member 320 can be attracted to each other by magnetic force. Of course, the first connecting member 210 and the second connecting member 320 can also be detachably connected by bonding or snapping to achieve the corresponding action.

[0051] When the dishwasher needs to open the door body 200, the driving assembly 300 can push the first connecting member 210 through the second connecting member 320, so that the second locking member 220 disengages the first locking member 120, thereby opening the door body 200; when the dishwasher needs to close the door, the driving assembly 300 can connect to the first connecting member 210 through the second connecting member 320, and then drive the door body 200 to rotate, so that the second locking member 220 engages with the first locking member 120, thereby closing the door body 200, so that the dishwasher can automatically close the door after opening the door for drying, thereby eliminating the need for manual closing of the door, greatly improving the convenience of using the dishwasher, and at the same time eliminating the health risks caused by the dishwasher having the door body 200 not closed for a long time, thereby improving the user experience.

[0052] It is understandable that in order to be able to drive the second connecting member 320 to move, the driving assembly 300 is provided with a telescopic rod 310, and the telescopic rod 310 can be telescopically moved. The second connecting member 320 is movably connected to the telescopic rod 310, so the driving assembly 300 can drive the second connecting member 320 to move through the telescopic movement of the telescopic rod 310 to achieve the corresponding function. In addition, since the second connecting member 320 is movably connected to the telescopic rod 310, the second connecting member 320 has a certain movable space relative to the telescopic rod 310, thereby facilitating the connection between the second connecting member 320 and the first connecting member 210. It should be noted that when the dishwasher door is opened, the door body 200 will rotate a certain angle relative to the box body 100, so that an angle is formed between the second connecting member 320 located at the door body 200 and the first connecting member 210 located at the box body 100, making it difficult for the first connecting member 210 and the second connecting member 320 to align and contact to achieve the corresponding action. For this reason, refer to Figure 2 、 Figure 4 and Figure 5 ,in, Figure 4 is a schematic diagram of the connection structure between the telescopic rod 310 and the second connecting member 320, Figure 5 3 is a cross-sectional view of the telescopic rod 310 and the second connecting member 320. In some embodiments of the present invention, the drive assembly 300 is provided with a telescopic rod 310, and the second connecting member 320 is connected to the end of the telescopic rod 310, and the second connecting member 320 can be vertically (i.e. Figure 1 When the dishwasher door is opened, the telescopic rod 310 drives the second connecting member 320 to move, and the second connecting member 320 pushes the first connecting member 210 to drive the door body 200 to open. During the door opening process, the second connecting member 320 can swing vertically downward under the action of its own gravity, thereby reducing the angle between the second connecting member 320 and the first connecting member 210, so that the second connecting member 320 can maintain alignment and contact with the first connecting member 210, so that the second connecting member 320 and the first connecting member 210 can cooperate well to achieve corresponding actions. Similarly, refer to Figures 6 to 9 ,in, Figure 6 is a schematic diagram of the dishwasher door 200 in an open state, Figure 7 This is a state diagram of the driving component 300 driving the second connecting member 320 to move toward the first connecting member 210. Figure 8 This is a schematic diagram of the second connecting member 320 being aligned with the first connecting member 210 and connected. Figure 9 This is a schematic diagram of the second connecting member 320 driving the door body 200 to close by connecting to the first connecting member 210. When the dishwasher is closed, the door body 200 has been opened to a certain angle relative to the cabinet 100. The telescopic rod 310 drives the second connecting member 320 to move. The second connecting member 320 can swing vertically downward under the action of its own gravity, thereby reducing the angle between the second connecting member 320 and the first connecting member 210, so that when the second connecting member 320 moves to the vicinity of the first connecting member 210, it can align and contact with the first connecting member 210, so that the second connecting member 320 and the first connecting member 210 can cooperate well to achieve corresponding actions.

[0053] In the above embodiment, in order to enable the second connecting member 320 to swing relative to the telescopic rod 310, refer to Figure 4 and Figure 5 In some embodiments of the present invention, the drive assembly 300 further includes a connecting rod 330, one end of which is movably connected to the telescopic rod 310, and the other end of which is movably connected to the second connecting member 320. Furthermore, at least one end of the connecting rod 330 is capable of vertically swinging relative to the telescopic rod 310 or the second connecting member 320, thereby allowing the second connecting member 320 to swing a certain angle relative to the telescopic rod 310. When the drive assembly 300 drives the second connecting member 320, the telescopic rod 310 drives the second connecting member 320 toward the first connecting member 210 via the connecting rod 330. Under the action of its own weight, the second connecting member 320 swings downward relative to the telescopic rod 310, thereby reducing the angle between the second connecting member 320 and the first connecting member 210, allowing the second connecting member 320 to better align and contact with the first connecting member 210, thereby ensuring that the second connecting member 320 and the first connecting member 210 cooperate well to achieve the corresponding movement.

[0054] Reference Figure 4 and Figure 5In order to enable the connecting rod 330 to swing smoothly relative to the telescopic rod 310 and / or the second connecting member 320, in some embodiments of the present invention, a hinge joint 331 is provided at the end of the connecting rod 330. The hinge joint 331 is roughly hemispherical, and the telescopic rod 310 and / or the second connecting member 320 are provided with a hinge groove 311 that cooperates with the hinge joint 331. The hinge groove 311 is also roughly hemispherical. The hinge joint 331 is installed in the hinge groove 311 and can rotate in the hinge groove 311, so that the connecting rod 330 can swing smoothly relative to the telescopic rod 310 and / or the second connecting member 320. For example, one end of the connecting rod 330 is provided with a hinge joint 331, and the end of the telescopic rod 310 is provided with a hinge groove 311. The connecting rod 330 can swing relative to the telescopic rod 310, so that the second connecting member 320 also swings relative to the telescopic rod 310. Refer to Figure 5 Of course, both ends of the connecting rod 330 can also be provided with hinge joints 331, and the ends of the telescopic rod 310 and the second connecting member 320 are both provided with hinge grooves 311, so that the connecting rod 330 can swing relative to the telescopic rod 310, and can also swing relative to the second connecting member 320. By providing two hinge joints 331 on the connecting rod 330, the second connecting member 320 can swing to a larger angle relative to the telescopic rod 310 in a smaller space.

[0055] It is understandable that when the swing angle of the second connecting member 320 relative to the telescopic rod 310 is too large, it is easy to cause the second connecting member 320 to deviate from the first connecting member 210 and fail to align. Therefore, in order to limit the swing angle of the second connecting member 320 relative to the telescopic rod 310, refer to Figure 5 In some embodiments of the present invention, the hinge groove 311 is provided with a limiting portion 312, and the limiting portion 312 is located at the opening of the hinge groove 311. When the hinge head 331 swings to the limiting portion 312 in the hinge groove 311, the limiting portion 312 can prevent the hinge head 331 from continuing to rotate, thereby limiting the swing angle of the hinge head 331, and further limiting the maximum swing angle of the second connecting member 320 relative to the telescopic rod 310, thereby preventing the second connecting member 320 from swinging too much relative to the telescopic rod 310.

[0056] It should be noted that in order to enable the second connecting member 320 to be more accurately aligned with the first connecting member 210, the angle difference range between the swing angle of the second connecting member 320 relative to the telescopic rod 310 and the opening angle of the door body 200 should not be too large. For this reason, in some embodiments of the present invention, the maximum swing angle of the second connecting member 320 relative to the telescopic rod 310 and the maximum opening angle of the door body 200 have an angle difference α, and α satisfies: -5°≤α≤5°, so that the angle difference between the swing angle of the second connecting member 320 relative to the telescopic rod 310 and the opening angle of the door body 200 is within a relatively small range. Within this angle difference range, the second connecting member 320 can be more accurately aligned with the first connecting member 210, and the angle difference range will not be too small, so as to avoid excessive assembly precision and increased assembly difficulty and cost.

[0057] It is understood that in some embodiments of the present invention, one of the first connecting member 210 and the second connecting member 320 is an electromagnet, and the other is magnetically attracted. When energized, the electromagnet generates magnetism, thereby allowing the first connecting member 210 and the second connecting member 320 to be attracted to each other and connected, thereby achieving the door opening or closing action.

[0058] In the above embodiment, specifically, the first connecting member 210 is an electromagnet, and the electromagnet is connected to a controller. The controller can control the electromagnet to be energized to generate magnetism, and can also control the electromagnet to be deenergized and demagnetized. The controller can adopt a common single-chip microcomputer controller. The second connecting member 320 can be a magnet, or a magnetic material that can be magnetically attracted, such as a metal member such as an iron-nickel alloy. Since the first connecting member 210 is an electromagnet, its magnetism can be generated by the control of the controller. When the door body 200 is opened to a set angle, the controller controls the electromagnet to be deenergized and demagnetized, so that the second connecting member 320 can be separated from the adsorption of the first connecting member 210, so that the drive assembly 300 can drive the second connecting member 320 to return to its original position, and during the process of opening the door, the electromagnet can remain energized to generate magnetism, so that the first connecting member 210 can maintain adsorption contact with the second connecting member 320, making the process of opening the door body 200 smoother.

[0059] As will be appreciated, dishwashers are typically placed indoors, making them easily accessible to children. Opening the dishwasher door 200 can pose a safety hazard. To prevent children from opening the dishwasher door 200 at will, some embodiments of the present invention include a child lock feature. When the dishwasher is in operation, such as during washing or disinfection, the door 200 is closed, and the second locking member 220 engages with the first locking member 120. When the child lock feature is enabled, the controller controls the first connecting member 210 to remain energized, generating magnetism that keeps the first connecting member 210 attached to the second connecting member 320, significantly increasing the force required to open the door and thus preventing children from opening the door 200. Of course, when the child lock feature is disabled, the controller controls the first connecting member 210 to demagnetize and deenergize the first connecting member 210. The door 200 remains closed to the opening 110 of the housing 100 solely through the engagement of the first locking member 120 and the second locking member 220. In this case, the door 200 can be opened with minimal force, making it easier for the user to use the dishwasher.

[0060] In order to enable the telescopic rod 310 to drive the second connecting member 320 to move via the connecting rod 330, it is understood that in some embodiments of the present invention, the drive assembly 300 is further provided with a drive member for driving the telescopic rod 310. The drive member may be a motor drive mechanism, a cylinder drive mechanism, or a thermal expansion drive mechanism. For example, the drive member is a motor drive mechanism, which may include a motor and a screw. The telescopic rod 310 is threadedly connected to the screw. During operation, the output shaft of the motor drives the screw to rotate, which drives the telescopic rod 310 to move axially along the screw. The telescopic rod 310 drives the second connecting member 320 to move via the connecting rod 330. Of course, the motor drive mechanism may also have other structural forms. When the driving member is a pneumatic cylinder drive mechanism, the telescopic rod 310 can be fixedly connected to the push rod of the cylinder, so that when the push rod is extended or retracted, it can drive the telescopic rod 310 to move. Of course, the push rod of the cylinder can also directly serve as the telescopic rod 310 of the drive assembly 300. In this case, the structure is simpler. The cylinder directly drives the telescopic rod 310 to move, thereby driving the second connecting member 320 to move via the connecting rod 330. Alternatively, the driving member can be a thermal expansion drive mechanism, such as a wax motor mechanism. The wax motor mechanism can drive the telescopic rod 310 to move by melting and expanding or solidifying and contracting the wax medium inside it.

[0061] In order to make the telescopic action of the telescopic rod 310 more stable, refer to Figure 3 , Figure 3This is a schematic diagram of the structure of a drive assembly according to some embodiments of the present invention. In some embodiments of the present invention, the drive assembly 300 is further provided with a sleeve 340, and the telescopic rod 310 is movably disposed within the sleeve 340. Therefore, when the telescopic rod 310 telescopes, the telescopic rod 310 can move axially within the sleeve 340. This makes the telescopic movement of the telescopic rod 310 smoother, prevents the telescopic rod 310 from shaking at an excessive angle and affecting the alignment of the second connecting member 320 and the first connecting member 210, and helps to improve the smoothness of opening and closing the dishwasher door.

[0062] In the above embodiment, in order to fix the sleeve 340, refer to Figure 3 In some embodiments of the present invention, the drive assembly 300 is further provided with a mounting plate 350, and the sleeve 340 is fixed to the housing 100 via the mounting plate 350. Specifically, the sleeve 340 can be fixed to the mounting plate 350 by welding, clamping, or threading. The mounting plate 350 is provided with mounting holes, and the housing 100 is provided with screw holes corresponding to the mounting holes. The mounting plate 350 is fixed to the housing 100 by bolts passing through the mounting holes and the screw holes. Of course, the mounting plate 350 can also be fixed to the housing 100 by welding or other methods, which can also achieve the purpose of fixing the sleeve 340 to the housing 100.

[0063] It should be noted that, in some embodiments of the present invention, the drive assembly 300 includes a telescopic rod 310, and the end of the telescopic rod 310 constitutes the second connecting member 320. At this time, the telescopic rod 310 and the second connecting member 320 are combined into one, so that the structure of the drive assembly 300 is simpler. The telescopic rod 310 can be connected to the first connecting member 210 through telescopic movement, thereby realizing the action of opening or closing the door.

[0064] Of course, it is understood that in the above embodiment, the telescopic rod 310 is an elastic member and is therefore capable of elastic deformation. When the telescopic rod 310 is connected to the first connecting member 210 to open or close the door 200, the telescopic rod 310 can undergo adaptive elastic deformation, thereby making the telescopic rod 310 more smoothly telescopic and preventing it from getting stuck and becoming immobile.

[0065] It is understood that the engagement method between the second locking member 220 and the first locking member 120 can be specifically designed according to actual needs. For example, in some embodiments of the present invention, at least one of the second locking member 220 and the first locking member 120 is a magnetic member, and the second locking member 220 and the first locking member 120 engage through magnetic attraction, thereby locking the door body 200 to the box body 100. In other embodiments of the present invention, one of the second locking member 220 and the first locking member 120 has a slot and the other has a block, and the block is inserted into the slot so that the second locking member 220 and the first locking member 120 engage and engage, thereby locking the door body 200 to the box body 100. Of course, the second locking member 220 and the first locking member 120 can also have other structures, which are not listed here.

[0066] Reference Figure 2 It is understood that in order to enable the drive assembly 300 to overcome the locking force of the second locking member 220 and the first locking member 120 with less force to quickly open the door body 200, in some embodiments of the present invention, the first connecting member 210 is disposed close to the outer periphery of the second locking member 220. For example, the gap between the first connecting member 210 and the second locking member 220 is 5 mm to 20 mm, and the distance between the two is relatively small. Therefore, when the drive assembly 300 transmits the thrust to the first connecting member 210 through the second connecting member 320, due to the relatively small distance between the first connecting member 210 and the second locking member 220, the thrust of the drive assembly 300 can act more on the second locking member 220, thereby enabling the second locking member 220 to disengage from the first locking member 120 more quickly, thereby opening the door body 200. Similarly, when the dishwasher door is closed, the drive assembly 300 can also engage the second locking member 220 with the first locking member 120 with less force, thereby closing the door body 200. By configuring as above, the driving component 300 only requires a smaller driving force to meet the demand, thereby helping to reduce the cost of the driving component 300 .

[0067] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the spirit of the present invention.
