Similarly, referring to fig. 6 to 9, wherein, fig. 6 is a schematic view of the door 200 of the dishwasher in an open state, figure 7 is a view illustrating the driving assembly 300 driving the second link 320 to move toward the first link 210, fig. 8 is a schematic diagram of the connection of the second connecting member 320 aligned with the first connecting member 210, fig. 9 is a schematic diagram of the second connecting member 320 driving the door body 200 to close by connecting the first connecting member 210, when the dishwasher is closed, the door body 200 has been opened at 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 downwards along the vertical direction under the action of its own gravity, thereby, the included angle between the second connecting member 320 and the first connecting member 210 can be reduced, so that the second connecting member 320 can be aligned and contacted with the first connecting member 210 when moving to the vicinity of the first connecting member 210, so that the second connector 320 and the first connector 210 can be well engaged to achieve the corresponding action.

In the above embodiments, in order to make the second connecting member 320 swing relative to the telescopic rod 310, referring to fig. 4 and 5, in some embodiments of the present invention, the driving assembly 300 further includes a connecting rod 330, one end of the connecting rod 330 is movably connected to the telescopic rod 310, the other end of the connecting rod 330 is movably connected to the second connecting member 320, and at least one end of the connecting rod 330 can swing vertically relative to the telescopic rod 310 or the second connecting member 320, so that the second connecting member 320 can swing a certain angle relative to the telescopic rod 310. When the driving assembly 300 drives the second connecting member 320, the telescopic rod 310 drives the second connecting member 320 to move towards the first connecting member 210 through the connecting rod 330, and the second connecting member 320 can swing downwards relative to the telescopic rod 310 under the action of self gravity, so that the included angle between the second connecting member 320 and the first connecting member 210 can be reduced, the second connecting member 320 can be in alignment contact with the first connecting member 210 better, and the second connecting member 320 and the first connecting member 210 can be matched well to realize corresponding actions.

Referring to fig. 4 and 5, in order to enable the connecting rod 330 to smoothly swing with respect to the telescopic rod 310 and/or the second connecting member 320, in some embodiments of the present invention, the end of the connecting rod 330 is provided with a hinge 331, the hinge 331 is substantially hemispherical, the telescopic rod 310 and/or the second connecting member 320 is provided with a hinge slot 311 engaged with the hinge 331, and the hinge slot 311 is also substantially hemispherical. The hinge 331 is installed in the hinge slot 311 and can rotate in the hinge slot 311, thereby allowing the connecting rod 330 to smoothly swing with respect 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 331, the end of the telescopic rod 310 is provided with a hinge slot 311, and 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. Referring to fig. 5, of course, both ends of the connecting rod 330 may also be provided with hinges 331, and both ends of the telescopic rod 310 and the second connecting member 320 are provided with hinge slots 311, so that the connecting rod 330 can swing relative to the telescopic rod 310 and also can swing relative to the second connecting member 320, and the connecting rod 330 enables the second connecting member 320 to swing relative to the telescopic rod 310 by a larger angle in a smaller space by providing two hinges 331.

It can be understood that, when the angle of the second connecting member 320 swinging relative to the telescopic rod 310 is too large, the second connecting member 320 is easily deviated from the first connecting member 210 and cannot be aligned, so as to limit the angle of the second connecting member 320 swinging relative to the telescopic rod 310, referring to fig. 5, in some embodiments of the present invention, the hinge slot 311 is provided with the limiting portion 312, the limiting portion 312 is located at the opening of the hinge slot 311, when the hinge 331 swings in the hinge slot 311 to the limiting portion 312, the limiting portion 312 can block the hinge 331 from continuing to rotate, so as to limit the angle of the hinge 331 swinging, further limit the maximum angle of the second connecting member 320 swinging relative to the telescopic rod 310, and prevent the angle of the second connecting member 320 swinging relative to the telescopic rod 310 from being too large.

It should be noted that, in order to make the second connecting member 320 align with the first connecting member 210 more accurately, 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 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 200 have an angle difference α, α satisfies: α is more than or equal to 5 ° and less than or equal to 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 which the second connecting member 320 can be aligned with the first connecting member 210 relatively accurately, and the range of the angle difference is not too small, thereby avoiding the problem that the assembling accuracy is too high and the assembling difficulty and cost are increased.

It is understood that in some embodiments of the present invention, one of the first connector 210 and the second connector 320 is an electromagnet, and the other is magnetically attracted. When the electromagnet is electrified, magnetism can be generated, so that the first connecting piece 210 and the second connecting piece 320 can be mutually adsorbed and connected, and the action of opening or closing the door can be realized.

In the above embodiment, specifically, the first connecting element 210 is an electromagnet, and the electromagnet is connected to a controller, and the controller can control the electromagnet to be powered on to generate magnetism and also can control the electromagnet to be powered off to demagnetize. The controller can adopt a common singlechip controller. The second connector 320 may be a magnet, or may be a magnetic material capable of being magnetically attracted, such as a metal member, e.g., an iron-nickel alloy. Since the first link 210 is an electromagnet, its magnetism can be generated by the controller control. When the door body 200 is opened to a set angle, the controller controls the electromagnet to be powered off and demagnetized, so that the second connecting piece 320 can be separated from the adsorption of the first connecting piece 210, the driving assembly 300 can drive the second connecting piece 320 to return to the original position, and in the process of opening the door, the electromagnet can be electrified to generate magnetism, so that the first connecting piece 210 can be kept in adsorption contact with the second connecting piece 320, and the process of opening the door body 200 is more stable.

It can be understood that the dish washer is placed indoor usually, therefore children more easily contact the dish washer, may cause certain potential safety hazard when the door body 200 of dish washer is opened to children, in order to prevent children from opening the door body 200 of dish washer at will the utility model discloses an in some embodiments, the dish washer still is provided with child lock function. When the dishwasher is in a washing or disinfecting working state, the door 200 is closed, and the second locking member 220 is engaged with the first locking member 120. When the dishwasher is unlocked with the child lock function, the controller controls the first connecting piece 210 to be electrified to generate magnetism, so that the first connecting piece 210 is kept adsorbed on the second connecting piece 320, thereby greatly increasing the force required for opening the door, and preventing a child from opening the door body 200. Certainly, when the child lock of the dishwasher is not unlocked, the controller controls the first connecting member 210 to be powered off and demagnetized, the door 200 is only closed at the opening 110 of the box 100 by the engagement of the first locking member 120 and the second locking member 220, and the door 200 can be opened with a small force at this time, so as to facilitate the use of the user.

In order to enable the telescopic rod 310 to move along the second connecting member 320 through the connecting rod 330, it is understood that, in some embodiments of the present invention, the driving assembly 300 is further provided with a driving member for driving the telescopic rod 310, and the driving member may be a motor driving mechanism or a cylinder driving mechanism or a thermal expansion driving mechanism. For example, the driving member is a motor driving mechanism, the motor driving mechanism may include a motor and a screw rod, the telescopic rod 310 is sleeved on the screw rod in a threaded connection manner, during operation, an output shaft of the motor drives the screw rod to rotate, the screw rod drives the telescopic rod 310 to move along an axial direction of the screw rod, and the telescopic rod 310 drives the second connecting member 320 to move through the connecting rod 330. Of course, the motor drive can also have other configurations. When the driving piece was cylinder actuating mechanism, telescopic link 310 can fixed connection in the push rod of cylinder to can drive telescopic link 310 when making the push rod flexible and remove, of course, the push rod of cylinder also can directly regard as drive assembly 300's telescopic link 310, and the structure is simpler this moment, and cylinder direct drive telescopic link 310 removes, thereby drives the removal of second connecting piece 320 through connecting rod 330. Alternatively, the driving member may be a thermal expansion driving mechanism, such as a wax motor mechanism, which expands or contracts by melting or solidifying the wax medium therein, so as to drive the telescopic rod 310 to move.

In order to make the flexible action of telescopic link 310 more steady, refer to fig. 3, fig. 3 is the utility model discloses a drive assembly's of some embodiments structural schematic diagram the utility model discloses an in some embodiments, drive assembly 300 still is provided with sleeve 340, and telescopic link 310 activity sets up in sleeve 340, and therefore when telescopic link 310 telescopically removes, telescopic link 310 can be along sleeve 340's axial displacement in sleeve 340 to make telescopic link 310 telescopically remove more steady, prevent that telescopic link 310 from rocking too big angle and influence the alignment of second connecting piece 320 with first connecting piece 210, be favorable to improving the bowl washer and open, close the stationarity of door.

In the above embodiment, in order to fix the sleeve 340, referring to fig. 3, in some embodiments of the present invention, the driving assembly 300 is further provided with a mounting plate 350, and the sleeve 340 is fixed on the box 100 through the mounting plate 350. Specifically, the sleeve 340 may be fixed to the mounting plate 350 through welding, clamping, or threaded connection, the mounting plate 350 is provided with a mounting hole, the box body 100 is provided with a screw hole corresponding to the mounting hole, and the mounting plate 350 is fixed to the box body 100 by penetrating through the mounting hole and the screw hole by a bolt. Of course, the mounting plate 350 may be fixed to the case 100 by welding or the like, and the sleeve 340 may be fixed to the case 100.

It should be noted that, in some embodiments of the present invention, the driving assembly 300 includes the telescopic rod 310, the end of the telescopic rod 310 forms the second connecting member 320, and at this time, the telescopic rod 310 and the second connecting member 320 are integrated, so that the structure of the driving assembly 300 is simpler, and the telescopic rod 310 can be connected with the first connecting member 210 through telescopic movement, thereby realizing the door opening or closing motion.

Of course, it is understood that in the above embodiment, the telescopic rod 310 is an elastic member, so that it can be elastically deformed. When the telescopic rod 310 is connected with the first connecting member 210 to open or close the door body 200, the telescopic rod 310 can generate adaptive elastic deformation, so that the telescopic movement of the telescopic rod 310 is smoother, and the phenomenon that the telescopic rod is locked and cannot move is avoided.

It will be appreciated that the engagement 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 are coupled by magnetic attraction, so as to lock the door 200 to the cabinet 100. In other embodiments of the present invention, one of the second locking member 220 and the first locking member 120 has a locking groove, and the other has a locking block, and the locking block is clamped into the locking groove to allow the second locking member 220 and the first locking member 120 to be engaged with each other, so as to lock the door 200 to the cabinet 100. Of course, the second locking member 220 and the first locking member 120 may have other structures, which are not listed here.

Referring to fig. 2, it can be understood that, in order to enable the driving assembly 300 to overcome the locking force of the second locking member 220 and the first locking member 120 with a small force to rapidly open the door body 200, in some embodiments of the present invention, the first connecting member 210 is disposed near the outer circumference of the second locking member 220, for example, a gap between the first connecting member 210 and the second locking member 220 is 5mm to 20mm, and a distance between the first connecting member 210 and the second locking member 220 is relatively small, so when the driving assembly 300 transmits the pushing force to the first connecting member 210 through the second connecting member 320, the pushing force of the driving assembly 300 can act on the second locking member 220 more, so that the second locking member 220 can be disengaged from the first locking member 120 more rapidly, thereby opening the door body 200. Similarly, when the dishwasher is closed, the driving assembly 300 can couple the second locking member 220 to the first locking member 120 with a small force, so as to close the door 200. By the arrangement, the driving assembly 300 can meet the requirement by needing smaller driving force, thereby being beneficial to reducing the cost of the driving assembly 300.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge scope of those skilled in the art.
