[0048] This application discloses a dishwasher, which in some embodiments combines Figures 1 to 11As shown, the dishwasher includes a body and a door 1000. The body has a washing chamber and a latch. The door 1000 includes an unlocking member 1100 and a latch 1300. The unlocking member 1100 is reciprocating to a first position and a second position, and the unlocking member 1100 has a first abutment portion 1110. The latch 1300 is adapted to engage with the latch when the door 1000 closes the washing chamber to lock the door 1000. The latch 1300 has a pivot 1340 to be rotatably configured. The end of the pivot 1340 has a second abutment portion 1310. The second abutment portion 1310 extends circumferentially along the pivot 1340 and corresponds to the first abutment portion 1110. At least one of the first abutment portion 1110 and the second abutment portion 1310 is an inclined surface, so that they abut against each other when the unlocking member 1100 moves from the first position to the second position, causing the latch 1300 to rotate and disengage from the latch. When the first abutting part 1110 and the second abutting part 1310 abut together, a component force is generated along the circumference of the rotating shaft 1340 by the action of the inclined surface. This controls the door latch 1300 to rotate and separate from the latch position, thereby unlocking the door 1000.

[0049] Specifically, the dishwasher includes a main body and a door 1000. The main body has a washing chamber, and the door 1000 can move between an open position and a closed position. When the door 1000 is in the closed position, the washing chamber is closed; when the door 1000 is in the open position, the washing chamber is open. Generally, the door 1000 is vertically positioned when in the closed position and horizontally positioned when in the open position. The washing chamber is used to install a dish rack, which can slide in and out of the washing chamber to facilitate loading and unloading of tableware. The tableware includes washable items, including but not limited to bowls, plates, cups, pots, knives, forks, and chopsticks.

[0050] The door 1000 needs to be in a locked state to close the washing chamber, while the washing chamber can be opened when the door 1000 is in an unlocked state. The implementation of the locked and unlocked states of the door 1000 can refer to relevant technologies. For example, the door 1000 includes a latch 1300, and the machine body includes a latch. The door 1000 is locked by engaging with the latch 1300 and the latch of the machine body, thus placing the door 1000 in a locked state. The door 1000 is unlocked by disengaging from the latch 1300 and the latch of the machine body, thus placing the door 1000 in an unlocked state. Generally, the door 1000 is rotatable. When the washing chamber needs to be closed, the door 1000 rotates closer to the washing chamber. As the door 1000 closes to the end, the latch 1300 engages with the body's latch, locking the door 1000. When the washing chamber needs to be opened, the latch 1300 disengages from the body's latch, unlocking the door 1000, allowing the door 1000 to rotate away from the washing chamber.

[0051] The door 1000 can be switched from a locked state to an unlocked state by controlling the unlocking component 1100. The unlocking component 1100 is movable, allowing it to move to both a first and a second position. The unlocking component 1100 can move in various ways, including but not limited to translation, rotation, extension, and deformation. When the door 1000 is in the locked state, the unlocking component 1100 is in the first position. Moving the unlocking component 1100 from the first position to the second position switches the door 1000 from the locked state to the unlocked state.

[0052] When the unlocking component 1100 moves from the first position to the second position, it needs to drive the door latch 1300 to disengage from the latch position in order to unlock the door 1000. Specifically, the unlocking component 1100 is provided with a first abutment portion 1110, and the door latch 1300 is provided with a pivot 1340 so that it can be rotatably configured through the pivot 1340. At the end of the pivot 1340, there is a second abutment portion 1310. The second abutment portion 1310 extends circumferentially along the pivot 1340 and corresponds to the first abutment portion 1110. At least one of the first abutment portion 1110 and the second abutment portion 1310 is an inclined surface. When the unlocking component 1100 moves from the first position to the second position, the first abutment portion 1110 abuts against the second abutment portion 1310. Through the action of the inclined surface, a force can be generated along the circumferential direction of the pivot 1340. This force causes the pivot 1340 to rotate, thereby causing the door latch 1300 to rotate and disengage from the latch position, thus unlocking the door 1000.

[0053] The movement of the unlocking component 1100 from the first position to the second position can be achieved manually. The so-called manual operation means that the user can apply force to the unlocking component 1100, thereby moving the unlocking component 1100 from the first position to the second position. When the unlocking component 1100 moves to the second position, the door 1000 is switched from the locked state to the unlocked state, thus realizing the manual unlocking of the door 1000.

[0054] Optionally, in some embodiments, combined with Figure 10 and Figure 11 As shown, both the first abutting part 1110 and the second abutting part 1310 are inclined surfaces and extend around the rotation axis of the rotating shaft 1340, thus presenting a spiral structure. The first abutting part 1110 and the second abutting part 1310 achieve surface contact when they abut, and can still maintain surface contact during the rotation of the rotating shaft 1340. This makes the point of force application form in the circumference of the rotating shaft 1340, which is more conducive to the rotation of the rotating shaft 1340.

[0055] In some embodiments, the end of the rotating shaft 1340 is provided with at least two second abutment portions 1310 arranged alternately along its circumference. The second abutment portions 1310 correspond one-to-one with the first abutment portions 1110. Thus, when the unlocking member 1100 moves from the first position to the second position, there are at least two points of force application in the circumference of the rotating shaft 1340, which is more conducive to the rotation of the rotating shaft 1340. In particular, when at least two second abutment portions 1310 are symmetrically distributed, the rotation of the rotating shaft 1340 can be made smoother, further improving the unlocking experience.

[0056] In some embodiments, combined with Figure 5 , Figure 8 , Figure 10 and Figure 11 As shown, the unlocking member 1100 is provided with a third abutment portion 1130, the rotating shaft 1340 is provided with a support arm 1320, the rotation axes of the support arm 1320 and the rotating shaft 1340 intersect, the support arm 1320 is provided with a fourth abutment portion 1321, at least one of the third abutment portion 1130 and the fourth abutment portion 1321 is an inclined surface, so as to abut against each other when the unlocking member 1100 moves from the first position to the second position, thereby causing the door latch 1300 to rotate and disengage from the latch position.

[0057] With the support arm 1320, the contact points of the third abutment portion 1130 and the fourth abutment portion 1321 are at a certain distance from the rotation axis of the rotating shaft 1340, thus forming a certain lever arm. The longer the lever arm, the less force the user needs to apply, which is more conducive to the user operating the unlocking component 1100. The support arm 1320 helps to improve the operating experience. For example, the third abutment portion 1130 has a slope, and the fourth abutment portion 1321 is perpendicular to the rotating shaft 1340. The third abutment portion 1130 abuts against one side of the fourth abutment portion 1321 through its slope, thereby causing the rotating shaft 1340 to rotate.

[0058] Combination Figures 1 to 11 As shown, in some embodiments, the unlocking member 1100 is disposed on the peripheral surface 1004 of the door body 1000, the peripheral surface 1004 of the door body 1000 surrounds the front surface 1003 of the door body 1000, and the side of the door body 1000 that is away from the washing chamber of the dishwasher is the front surface 1003.

[0059] The user operates the unlocking component 1100 to manually unlock the door 1000. The unlocking component 1100 is located on the peripheral surface 1004 of the door 1000, eliminating the need to drill a hole in the front surface 1003 of the door 1000 for the installation of the unlocking component 1100. The front surface 1003 of the door 1000 has a stronger sense of unity. Since the peripheral surface 1004 is less likely to appear in the user's field of vision than the front surface 1003, it helps to reduce the sense of discontinuity caused by the installation of the unlocking component 1100.

[0060] In related technologies, the unlocking element 1100 is located on the front 1003 of the door 1000. Since the user typically stands in front of the dishwasher, with the front of the door 1000 facing the user, the front of the door 1000 corresponds to the front 1003. That is, when the washing chamber is closed, the door 1000 is on the side facing away from the washing chamber. The unlocking element 1100 is located on the front 1003 of the door 1000, allowing the user to operate it from the front 1003. This solution requires an opening in the front 1003 of the door 1000 for installing the unlocking element 1100, thus compromising the integrity of the front 1003 of the door 1000. Furthermore, since the user is usually facing the front 1003 of the door 1000, this negatively impacts the visual appeal.

[0061] Therefore, in this embodiment, the unlocking member 1100 is disposed on the peripheral surface 1004 of the door body 1000, the peripheral surface 1004 of the door body 1000 surrounds the front surface 1003 of the door body 1000, and the side of the door body 1000 that is away from the washing chamber of the dishwasher is the front surface 1003. Taking the closed washing chamber state of door 1000 as a reference, with door 1000 vertically positioned and the side of door 1000 facing away from the washing chamber as the front 1003, the upper, left, right, and lower sides of door 1000 form a perimeter 1004 surrounding the front 1003 of door 1000. For example, an unlocking element 1100 can be located on the left side of door 1000, meaning the unlocking element 1100 is located on the left perimeter 1004 of door 1000. Alternatively, the unlocking element 1100 can be located on the right side of door 1000, meaning the unlocking element 1100 is located on the right perimeter 1004 of door 1000. Because the unlocking element 1100 is located on the perimeter 1004, the user can operate the unlocking element 1100 from the perimeter 1004 of door 1000, achieving lateral unlocking of door 1000. Since users are mostly facing the front 1003 of the door 1000, the peripheral 1004 of the door 1000 is less likely to appear in the user's field of vision. By setting the unlocking component 1100 on the peripheral 1004 of the door 1000, it helps to improve the integrity of the front 1003 of the door 1000 and reduce the sense of discontinuity caused by setting the unlocking component 1100.

[0062] The movement of the unlocking component 1100 is a reciprocating movement. The unlocking component 1100 can move from a first position to a second position along a first direction, and can move from a second position to a first position along a second direction opposite to the first direction. The first direction can be... Figure 1 The direction shown is from right to left; the second direction can be... Figure 1 As shown in the left-to-right direction, the reciprocating motion of the unlocking member 1100 helps to simplify the structure. In this embodiment, the reciprocating motion of the unlocking member 1100 is a linear reciprocating movement.

[0063] Optionally, the reciprocating direction of the unlocking component 1100 intersects with the thickness direction of the door body 1000. When the door body 1000 closes the washing chamber, it is vertically positioned, with its thickness direction being the front-to-back direction. When the door body 1000 opens the washing chamber, it is horizontally positioned, with its thickness direction being the up-to-down direction. The intersection of the reciprocating direction of the unlocking component 1100 and the thickness direction of the door body 1000 ensures sufficient space for its reciprocating movement while preventing the door body 1000 from becoming excessively thick. For example, the reciprocating movement of the unlocking component 1100 could be linear, with the reciprocating direction being left-to-right.

[0064] The reciprocating movement of the unlocking component 1100 between the first and second positions is achieved through the following scheme, combined with Figures 3 to 9 As shown, in some embodiments, the peripheral surface 1004 of the door body 1000 is provided with a mounting hole 1005, and the unlocking member 1100 is provided with a buckle 1120. The unlocking member 1100 is fastened to the mounting hole 1005 by the buckle 1120. The buckle 1120 is adapted to abut against the periphery of the mounting hole 1005 when the unlocking member 1100 is in a first position, and is adapted to disengage from at least a portion of the periphery of the mounting hole 1005 when the unlocking member 1100 moves from the first position to a second position.

[0065] The unlocking component 1100, through the setting of the latch 1120, allows the latch 1120 to be inserted into the mounting hole 1005 from the outside in, facilitating assembly, when the unlocking component 1100 is installed in the mounting hole 1005. When the unlocking component 1100 is in the first position, the latch 1120 abuts against the periphery of the mounting hole 1005, and the periphery of the mounting hole 1005 blocks the latch 1120 in the direction in which the unlocking component 1100 disengages from the mounting hole 1005, thereby preventing the unlocking component 1100 from disengaging from the mounting hole 1005. When the unlocking component 1100 moves from the first position to the second position, at least a portion of the periphery of the latch 1120 disengages from the mounting hole 1005, allowing the unlocking component 1100 to move to the second position and unlock the door 1000. The presence of the door latch 1300 acts as a stop for the unlocking component 1100, positioning the unlocking component 1100 in the current position (second position). With this configuration, the user can manually press to apply force to the unlocking component 1100, thereby moving the unlocking component 1100 from the first position to the second position, for example... Figures 3 to 8 As shown, the user presses the unlocking component 1100 and moves it from right to left to unlock the door 1000.

[0066] Understandably, after unlocking the door 1000, the user releases the force applied to the unlocking component 1100. The unlocking component 1100 needs to move from the second position to the first position to reset. When the unlocking component 1100 moves from the second position to the first position, it is abutted by the periphery of the latch 1120 and the mounting hole 1005, thereby limiting the unlocking component 1100 to the current position (first position).

[0067] To facilitate the reset of the unlocking member 1100, in some embodiments, the unlocking member 1100 is adapted to move from the second position to the first position under the action of elastic force. The elastic force is provided by an elastic element (compression spring 1610 hereinafter). That is, when the unlocking member 1100 moves to the second position, the elastic element deforms to generate an elastic force on the unlocking member 1100. When the user cancels the operation on the unlocking member 1100, the elastic element releases its elastic potential energy, and the elastic force generated by the elastic element causes the unlocking member 1100 to automatically move to the first position and reset.

[0068] Specifically, combined Figure 5 and Figure 8 As shown, a compression spring 1610 is provided between the unlocking member 1100 and the rotating shaft 1340. The compression spring 1610 surrounds the rotation axis of the rotating shaft 1340. The unlocking member 1100 is adapted to move from the second position to the first position under the elastic force generated by the compression spring 1610.

[0069] The compression spring 1610 exerts a force on the unlocking member 1100, causing the unlocking member 1100 to tend to move from the second position towards the first position, facilitating the reset of the unlocking member 1100. When the user applies force to the unlocking member 1100 to move it from the first position to the second position, the compression spring 1610 undergoes elastic deformation and exerts a force on the unlocking member 1100. The force applied by the user overcomes the elastic force generated by the elastic deformation of the compression spring 1610, thereby causing the unlocking member 1100 to move to the second position, and the door 1000 switches to the unlocked state, allowing the washing chamber to be opened. Then, when the user releases the force applied to the unlocking member 1100, the compression spring 1610 releases its elastic potential energy, and the unlocking member 1100 moves back to the first position under the action of the elastic force of the compression spring 1610. The compression spring 1610 facilitates the reset of the unlocking member 1100. Since the compression spring 1610 surrounds the rotation axis of the rotating shaft 1340, it can effectively prevent the rotation of the rotating shaft 1340 from causing the compression spring 1610 to twist, thus ensuring the normal operation of the compression spring 1610.

[0070] Combination Figure 9As shown, in some embodiments, the dishwasher's peripheral surface 1004 is provided with a groove 1006, which forms a handle, and the unlocking member 1100 is exposed in the groove 1006. The groove 1006 forms a handle, and after unlocking the door 1000, the user can pull the door 1000 to open the washing chamber by holding the handle. Since the unlocking member 1100 is exposed in the groove 1006, the user can immediately hold the handle after unlocking the door 1000 using the unlocking member 1100, without needing to move their hand significantly, thus improving the unlocking experience of the door 1000.

[0071] The explanation is based on the body including the fasteners, combined with Figures 1 to 11 As shown, in some embodiments, the latch 1300 is in a third position when engaged with the latch and in a fourth position when disengaged from the latch. The latch 1300 is adapted to rotate from the fourth position to the third position under the action of a spring force. That is, when the latch 1300 is in the third position, it can be held in the current position by the action of a spring force to maintain the locking of the door 1000. When the latch 1300 is in the fourth position, it can be rotated towards the third position by the action of a spring force, thus facilitating the reset of the latch 1300. The spring force can be provided by an elastic element, such as a tension spring 1620. When the door 1000 is locked, the latch 1300 is held in the third position by the action of the elastic force, thus maintaining the lock on the door 1000. When the door 1000 is unlocked, the user operates the unlocking component 1100 from the first position to the second position, which drives the latch 1300 to rotate from the third position to the fourth position. When the latch 1300 rotates to the fourth position, it disengages from the latch, allowing the door 1000 to switch to the unlocked state and open the washing chamber. At this time, the tension spring 1620 undergoes elastic deformation and generates force on the latch 1300. When the user cancels the operation of the unlocking component 1100, the unlocking component 1100 moves from the second position to the first position to reset (e.g., the unlocking component 1100 resets under the action of the elastic force provided by the compression spring 1610). The tension spring 1620 releases its elastic potential energy, and the latch 1300 rotates to the third position to reset under the action of the elastic force.

[0072] Optionally, in some embodiments, the door latch 1300 is provided with a stop slope 1301, which is adapted to abut against the latch when the door 1000 closes the washing chamber, so as to first rotate to avoid the latch and then rotate in the opposite direction to engage with the latch.

[0073] When the washing chamber is closed, as the door 1000 gradually approaches the washing chamber, the latch 1300 abuts against the stop slope 1301 and the latch position. The latch position generates a component force on the stop slope 1301, which forces the latch 1300 to rotate and avoid the latch position. As the door 1000 is closed in place, the door 1000 rotates in the opposite direction to engage with the latch position. In this way, the latch position blocks the latch 1300 in the direction that the latch 1300 leaves the washing chamber, thus locking the door 1000. For example, the initial position of the latch 1300 is the third position. As the door 1000 gradually approaches the washing chamber, the stop slope 1301 abuts against the latch position, and the latch 1300 rotates to the fourth position to avoid the latch position due to the component force generated by the latch position. As the door 1000 is closed in place, the door 1000 rotates in the opposite direction to the third position to engage with the latch position.

[0074] When the washing chamber is opened, the user applies force to the unlocking member 1100, causing it to move from the first position to the second position. The unlocking member 1100 then rotates the door latch 1300 from the third position to the fourth position, disengaging the door latch 1300 from the latch and unlocking the door 1000. This allows the door 1000 to be moved away from the washing chamber, thus opening the washing chamber. After unlocking the door 1000, the user releases the force applied to the unlocking member 1100. Under the action of the elastic force (compression spring 1610), the unlocking member 1100 moves from the second position to (reset) the first position, and the door latch 1300 rotates from the fourth position to (reset) the third position under the action of the elastic force (tension spring 1620).

[0075] Combination Figures 12 to 16 As shown, in some embodiments, the door 1000 further includes a drive mechanism 1500, which is adapted to disengage the door latch 1300 from the latch position. By setting the drive mechanism 1500, automatic opening and unlocking can be achieved in addition to manual unlocking, which helps to realize automatic door opening and drying after the dishwasher finishes washing.

[0076] The drive mechanism 1500 is a device for outputting mechanical energy. The drive mechanism 1500 is used to couple with the door latch 1300 and to drive the door latch 1300 to disengage from the latch position. That is, when it is necessary to unlock the door body 1000, the drive mechanism 1500 drives the door latch 1300 to rotate from the third position to the fourth position, thereby causing the door latch 1300 to disengage from the latch position.

[0077] For example, after the dishwasher finishes washing, the washing chamber is in a high temperature and high humidity environment. The drive mechanism 1500 can drive the door latch 1300 to rotate from the third position to the fourth position, so that the door 1000 switches from the locked state to the unlocked state. The door 1000 can then automatically open the washing chamber (e.g., the door 1000 opens at a certain angle under the action of gravity, or other solutions are adopted), and the high temperature and high humidity gas in the washing chamber overflows, realizing automatic door opening and drying.

[0078] Optionally, combined Figure 1 As shown, the drive mechanism 1500 includes a drive rod 1510 and a rotating shaft 1340 with a fifth abutment portion 1330. The drive rod 1510 is adapted to abut against the fifth abutment portion 1330 to drive the door latch 1300 to rotate, thereby disengaging the door latch 1300 from the latch position. When the drive mechanism 1500 is driven, the drive rod 1510 abuts against the fifth abutment portion 1330, transmitting power to the rotating shaft 1340, causing the rotating shaft 1340 to rotate and drive the door latch 1300 to rotate from the third position to the fourth position, thereby unlocking the door 1000.

[0079] Optionally, combined Figure 16 As shown, the fifth abutment portion 1330 extends along an axis perpendicular to the rotating shaft 1340, and the reciprocating direction of the drive rod 1510 intersects the axis of the rotating shaft 1340. Since the fifth abutment portion 1330 needs to cooperate with the drive mechanism 1500, by extending the fifth abutment portion 1330 perpendicular to the rotating shaft 1340 and in the vertical direction, the end of the fifth abutment portion 1330 is far away from the rotating shaft 1340, which facilitates the arrangement of the drive mechanism 1500.

[0080] Optionally, the fifth abutment portion 1330 and the second abutment portion 1310 are arranged alternately along the axial direction of the rotating shaft 1340. Since the fifth abutment portion 1330 needs to cooperate with the drive mechanism 1500 and the second abutment portion 1310 needs to cooperate with the unlocking member 1100, by arranging the fifth abutment portion 1330 and the second abutment portion 1310 alternately along the axial direction of the rotating shaft 1340, the unlocking member 1100 and the drive mechanism 1500 can also be arranged alternately, thus avoiding interference between the movement of the unlocking member 1100 and the movement of the drive mechanism 1500.

[0081] In some embodiments, combined with Figure 16 As shown, the drive rod 1510 has an inclined surface that abuts against the fifth abutment portion 1330, and / or the fifth abutment portion 1330 has an inclined surface that abuts against the drive rod 1510. The drive mechanism 1500 may include a motor, which outputs mechanical energy to drive the door latch 1300, or it may include a wax motor, which extends and retracts to drive the door latch 1300. Figure 16 As shown, taking the drive mechanism 1500 including a wax motor as an example, the wax motor is connected to the drive rod 1510, so that the drive rod 1510 can be driven to move up and down. When the drive rod 1510 moves from bottom to top, the drive rod 1510 abuts against the inclined surface of the fifth abutment part 1330 through its inclined surface, so that it is easy to generate a component force along the rotation direction of the rotating shaft 1340, thereby causing the rotating shaft 1340 to rotate.

[0082] Combination Figure 1 , Figure 2 and Figure 12As shown, in some embodiments, door latches 1300 are respectively provided on the left and right sides of the door body 1000. The door body 1000 also includes a connecting rod 1400, which connects the door latches 1300 on the left and right sides. Either door latch 1300 is adapted to drive the other door latch 1300 to rotate via the connecting rod 1400. By providing door latches 1300 on both the left and right sides, the locking effect of the door body 1000 is improved, thereby helping to provide the closing and sealing performance of the door body 1000. Correspondingly, an unlocking element 1100 is provided corresponding to the left door latch 1300 and the right door latch 1300. The user can unlock the door body 1000 by operating either unlocking element 1100 (left or right). The drive mechanism 1500 can be set to correspond to the door latch 1300 on the right or left side. By driving the door latch 1300 on the right or left side, the door latches 1300 on both sides can be driven to unlock the door 1000.

Any equivalent structural transformations made based on the concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
