[0048] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0049] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0050] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0052] Furthermore, the use of terms such as "first" and "second" in this application is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. If the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed in this application.

[0053] This application discloses a dishwasher, combined with Figures 1 to 9As shown, the dishwasher includes a door 1000, which has an unlocked state and a locked state. The door 1000 includes an unlocking member 1100 and a drive mechanism 1200. The unlocking member 1100 is movable to a first position and a second position. When the unlocking member 1100 is in the first position, the door 1000 is in the locked state. When the unlocking member 1100 is in the second position, the door 1000 is in the unlocked state. The unlocking member 1100 is adapted to be operated by an external force to move from the first position to the second position. The drive mechanism 1200 is used to drive the unlocking member 1100 from the first position to the second position.

[0054] The user can manually unlock the door 1000 using the unlocking device 1100. Manual unlocking allows the user to directly open the dishwasher's washing chamber. The door 1000 can be automatically unlocked through the cooperation of the drive mechanism 1200 and the unlocking device 1100. Automatic unlocking helps with opening the door for drying after the dishwasher has finished washing.

[0055] Specifically, the dishwasher includes a main body (not shown in the figure) and a door 1000. The main body has a washing chamber. 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 it is in the closed position and horizontally positioned when it is 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 the loading and unloading of tableware. The tableware includes washable items, including but not limited to bowls, plates, cups, pots, knives, forks, and chopsticks.

[0056] When the door 1000 moves to the closed position, it needs to be in a locked state to ensure that the door 1000 closes the washing chamber. When the door 1000 needs to open the washing chamber, it needs to switch from the locked state to the unlocked state so that the door 1000 can move from the closed position to the open position to open the washing chamber. The implementation of the unlocked and locked states of the door 1000 can refer to relevant technologies. For example, the door 1000 includes a latch 1300. When the door 1000 moves to the closed position, the door 1000 closes the washing chamber, and the latch 1300 needs to engage with the corresponding position (latch) on the machine body. In this way, the door 1000 is in a locked state and keeps the washing chamber closed. When the door 1000 needs to leave the closed position and move towards the open position, the latch 1300 needs to disengage from the corresponding position (latch) on the machine body. In this way, the door 1000 switches from the locked state to the unlocked state, and the door 1000 can move to the open position to open the washing chamber.

[0057] 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 locked, the unlocking component 1100 is in the first position, and moving from the first position to the second position switches the door 1000 from the locked state to the unlocked state. This movement can be achieved manually by the user applying force to the unlocking component 1000, thus switching the door 1000 from the locked state to the unlocked state.

[0058] Taking the door 1000 with a latch 1300 as an example, the unlocking component 1100 will be explained. When the door 1000 is in the closed position and the washing chamber is closed, the latch 1300 engages with the corresponding position (latch) on the machine body, and the door 1000 is in a locked state, with the unlocking component 1100 in the first position. When the user applies force to the unlocking component 1100 and moves it from the first position to the second position, the unlocking component 1100 disengages the latch 1300 from the corresponding position (latch) on the machine body, thereby switching the door 1000 from the locked state to the unlocked state. Thus, the door 1000 can move from the closed position to the open position, opening the washing chamber. Through the design of the unlocking component 1100, the user can directly operate the unlocking component 1100 to quickly unlock the door 1000.

[0059] In addition to manual unlocking, this embodiment also achieves automatic unlocking of the door 1000 by setting a drive mechanism 1200, which helps to realize automatic door opening and drying after the dishwasher finishes washing. The drive mechanism 1200 is a device for outputting mechanical energy. The drive mechanism 1200 is coupled to the unlocking member 1100 and is configured to drive the unlocking member 1100 from a first position to a second position. By driving the unlocking member 1100 from the first position to the second position through the drive mechanism 1200, the door 1000 is automatically unlocked.

[0060] For example, after the dishwasher finishes washing, the washing chamber is in a high temperature and high humidity environment. The unlocking part 1100 can be moved from the first position to the second position by the drive mechanism 1200, so that the door 1000 is switched from the locked state to the unlocked state. The door 1000 can automatically open the washing chamber (such as the door 1000 opening at a certain angle under the action of gravity, or other solutions). The high temperature and high humidity gas in the washing chamber will overflow, realizing automatic door opening and drying.

[0061] Combination Figure 3 , Figure 7 , Figure 14 and Figure 15 As shown, in some embodiments, the drive mechanism 1200 includes a reciprocating drive rod 1240, which is adapted to drive the unlocking member 1100 from a first position to a second position via the drive rod 1240. The reciprocating drive rod 1240 simplifies the structure. For example, the drive rod 1240 can reciprocate along a first direction and a second direction opposite to the first direction. When the drive rod 1240 moves along the first direction, it drives the unlocking member 1100 from the first position to the second position. When the drive rod 1240 moves along the second direction, it resets, at which point the unlocking member 1100 can reset (e.g., under the action of the second elastic member 1140). The first direction can be... Figure 3 The direction shown is from left to right; the second direction can be... Figure 3 The direction shown is from right to left.

[0062] Optionally, combined Figures 1 to 8 As shown, the reciprocating direction of the drive rod 1240 intersects the thickness direction of the door body 1000. When the door body 1000 is in the closed position and the washing chamber is closed, the door body 1000 is vertically positioned, and its thickness direction is the front-to-back direction. When the door body 1000 is in the open position and the washing chamber is open, the door body 1000 is horizontally positioned, and its thickness direction is the up-to-down direction. By intersecting the reciprocating direction of the drive rod 1240 with the thickness direction of the door body 1000, sufficient space is ensured for the reciprocating movement of the drive rod 1240, while also preventing the door body 1000 from being too thick. For example, the drive rod 1240 can reciprocate in the left-right direction, and this reciprocating movement can be linear.

[0063] Since the drive rod 1240 is designed to reciprocate, in order to make the reciprocating motion of the drive rod 1240 smoother, combined with Figure 10 As shown, in some embodiments, the door body 1000 is provided with a slide groove 1440, and the drive rod 1240 passes through the slide groove 1440, that is, the drive rod 1240 reciprocates within the slide groove 1440. The slide groove 1440 guides and limits the reciprocating movement of the drive rod 1240, thus making the reciprocating movement of the drive rod 1240 smoother. For example, the door body 1000 includes an inner door 1001 and an outer door 1002. The unlocking member 1100 is movably disposed in the inner door 1001, and the drive mechanism 1200 is disposed in the inner door 1001. The inner door 1001 is provided with a slide groove 1440.

[0064] The drive rod 1240 can be driven by a motor. However, since the drive rod 1240 is designed to reciprocate, and the motor outputs rotational mechanical energy, a relatively complex transmission structure is required between the motor and the drive rod 1240. To reduce the complexity of the structure, a combination of... Figure 14 and Figure 15 As shown, in some embodiments, the drive mechanism 1200 further includes a wax motor 1230, which is provided with a reciprocating push rod 1231. The push rod 1231 is connected to the drive rod 1240 and is adapted to drive the drive rod 1240 to reciprocate.

[0065] The wax motor 1230 is a driving component, mainly composed of a positive temperature coefficient thermistor (PTC). This PTC thermistor is mounted on a sealed container filled with solid wax. When the wax motor 1230 is energized, the solid wax is heated to a controllable temperature by the energized thermistor, causing it to melt and expand, thereby driving the push rod 1231 to move outward. When the wax motor 1230 is de-energized, the liquid wax cools, and the push rod 1231 returns to its original position. The specific structure of the wax motor 1230 is not limited to this; please refer to relevant technologies. The wax motor 1230 facilitates the reciprocating movement of the drive rod 1240.

[0066] Generally, the wax motor 1230 and the drive rod 1240 are manufactured separately. To facilitate coupling between the push rod 1231 and the drive rod 1240, [the following is a separate, unrelated section:] Figure 16 As shown, in some embodiments, the drive rod 1240 is provided with a slot 1242, and the end of the push rod 1231 is engaged in the slot 1242 to connect the push rod 1231 and the drive rod 1240. When assembling the wax motor 1230 and the drive rod 1240, the end of the push rod 1231 is engaged in the slot 1242, so that when the push rod 1231 reciprocates, it can drive the drive rod 1240 to reciprocate.

[0067] Combination Figure 14 and Figure 15As shown, in some embodiments, the drive mechanism 1200 further includes a housing 1210 and a first elastic member 1220. The wax motor 1230 is disposed within the housing 1210, and the first elastic member 1220 is disposed between the side of the wax motor 1230 away from the push rod 1231 and the housing 1210. The push rod 1231 drives the drive rod 1240 to reciprocate, thereby causing the drive rod 1240 to move the unlocking member 1100 from a first position to a second position. At the moment when the drive rod 1240 moves the unlocking member 1100, in order to avoid damage to the components caused by the impact generated by the wax motor 1230, the first elastic member 1220 is provided between the wax motor 1230 and the housing 1210. The first elastic member 1220 can play a buffering role, avoiding excessive impact between the drive rod 1240 and the unlocking member 1100, which helps to prevent damage to the components and also helps to reduce noise.

[0068] Combination Figure 9 As shown, in some embodiments, the unlocking member 1100 is located on the front of the door 1000. With the door 1000 in the closed position and the washing chamber closed as a reference, the user faces the door 1000, and the front of the door 1000 is opposite to the user. The front of the door 1000 is equivalent to the front view, that is, the side of the door 1000 away from the washing chamber when the washing chamber is closed. The unlocking member 1100 is located on the front of the door 1000, allowing the user to operate the unlocking member 1100 from the front of the door 1000, thus unlocking the door 1000 from the front. For example, the user manually presses (applies external force) the unlocking member 1100, causing it to move from the first position to the second position.

[0069] Optionally, the front of the door 1000 is provided with an opening 1430, and the unlocking member 1100 is disposed in the opening 1430, so that the unlocking member 1100 is exposed on the front of the door 1000. The unlocking member 1100 is disposed in the opening 1430, so that a part of the unlocking member 1100 is located inside the door 1000, which facilitates cooperation with other components. The user can operate the unlocking member 1100 through the opening 1430 to unlock the door 1000 from the front.

[0070] Optionally, when the unlocking component 1100 is in the first position, the unlocking component 1100 blocks the opening 1430; when the unlocking component 1100 moves from the first position to the second position, it leaves the opening 1430. The user can operate the unlocking component 1100 in a short time, and most of the time the unlocking component 1100 is in the first position. This setting can prevent foreign objects from entering the interior of the door 1000 through the opening 1430.

[0071] For example, see Figure 9As shown, the door 1000 includes an inner door 1001 and an outer door 1002. The outer door 1002 is located in front of the inner door 1001. The outer door 1002 is provided with an opening 1430. The unlocking member 1100 is movably disposed in the inner door 1001. When the unlocking member 1100 is in the first position, it blocks the opening 1430.

[0072] In some embodiments, the unlocking member 1100 is adapted to rotate a preset angle when pressed and to rotate in the opposite direction to reset when the external force disappears. The preset angle is greater than 0° and less than 90°. In this way, the unlocking member 1100 forms a reciprocating swinging motion. By limiting the rotation angle, the rotation space required by the unlocking member 1100 is reduced, which helps to make the structure more compact.

[0073] Combination Figures 9 to 13 As shown, in some embodiments, the door 1000 further includes a second elastic member 1140, which is adapted to exert a force on the unlocking member 1100 to cause the unlocking member 1100 to have a tendency to move from the second position toward the first position. The so-called tendency means that when the unlocking member 1100 leaves the first position, the second elastic member 1140 elastically deforms and exerts a force on the unlocking member 1100, which can cause the unlocking member 1100 to move toward the first position. Taking manual unlocking of the door 1000 as an example, when the user applies force to the unlocking element 1100 to move it from the first position to the second position, the second elastic element 1140 undergoes elastic deformation and generates force on the unlocking element 1100. The force applied by the user to the unlocking element 1100 overcomes the elastic force generated by the elastic deformation of the second elastic element 1140, thereby moving the unlocking element 1100 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 element 1100, the second elastic element 1140 releases its elastic potential energy, and the unlocking element 1100 moves back to the first position under the action of the elastic force of the second elastic element 1140. The second elastic element 1140 facilitates the reset of the unlocking element 1100. Similarly, when automatically unlocked by the drive mechanism, the unlocking element 1100 also resets via the second elastic element 1140.

[0074] Combination Figures 1 to 13 As shown, in some embodiments, the unlocking member 1100 is rotatably configured to rotate to a first position and a second position. That is, the unlocking member 1100's movement is rotational; it can rotate to the first and second positions, facilitating position switching. For example, if a user presses the unlocking member 1100 from front to back through the opening 1430, the unlocking member 1100 can rotate backward to the second position. Combined with... Figure 3 , Figure 7 and Figure 15As shown, the drive rod 1240 is provided with a guide ramp 1241, and the unlocking member 1100 is provided with a stop portion 1120. The guide ramp 1241 is adapted to abut against the stop portion 1120 to push the unlocking member 1100 from a first position to a second position. Due to the guide ramp 1241, when the guide ramp 1241 and the stop portion 1120 abut against each other, a component force can be generated in a direction perpendicular to the direction of movement of the drive rod 1240. This component force will drive the unlocking member 1100 to rotate from the first position to the second position. With this arrangement, the direction of movement of the drive rod 1240 and the direction of movement of the unlocking member 1100 can be different, which helps to make full use of space.

[0075] The rotatable setting of the unlocking component 1100 can be achieved by the following scheme: the door body 1000 includes an outer door 1002, an inner door 1001 and a first fixing block 1450. One of the inner door 1001 and the outer door 1002 is provided with a first support seat 1410. The unlocking component 1100 is provided with a first rotating shaft 1110. The first fixing block 1450 and the first support seat 1410 are connected to clamp the first rotating shaft 1110, so that the unlocking component 1100 can be rotatably set through the first rotating shaft 1110.

[0076] With the unlocking member 1100 rotatable, the second elastic member 1140 is a tension spring. The unlocking member 1100 is provided with a connecting arm 1130 intersecting its rotation axis. One end of the tension spring is connected to the connecting arm 1130, and the other end is fixed inside the door body 1000 (e.g., fixed to the inner door 1001). When the unlocking member 1100 rotates, the tension spring is stretched, and the tension spring exerts a pulling force on the unlocking member 1100, which causes the tension spring to return to its original position. It is understood that, with the unlocking member 1100 rotatable, the stop portion 1120 needs to be a certain distance from the rotation axis of the unlocking member 1100. When the guide slope 1241 and the stop portion 1120 abut, a rotational power arm is formed, facilitating the rotation of the unlocking member 1100. Optionally, the second elastic member 1140 and the drive mechanism 1200 are located on opposite sides of the unlocking member 1100, which is more conducive to the structural layout.

[0077] Combination Figures 1 to 9 as well as Figure 17As shown, in some embodiments, the door 1000 includes a latch 1300 and a connecting rod 1500. The latches 1300 are respectively provided on the left and right sides of the door 1000. The latches 1300 are movably configured. The latches 1300 are adapted to engage with the machine body to lock the door 1000 and close the washing chamber, and are adapted to disengage from the machine body to unlock the door 1000 and open the washing chamber. The latches 1300 are adapted to be in a third position when engaged with the machine body, and are adapted to disengage from the machine body when moving from the third position to the fourth position. The connecting rod 1500 connects the latches 1300 on the left and right sides. The unlocking member 1100 is adapted to abut against the connecting rod 1500 when moving from the first position to the second position, so that the connecting rod 1500 drives the latches 1300 on the left and right sides to move from the third position to the fourth position.

[0078] The door body has a latch. When latch 1300 engages with the latch, the door body 1000 is in a locked state. When latch 1300 is engaged with the latch, it is in the third position. When latch 1300 disengages from the latch, the door body 1000 is in the unlocked state. When latch 1300 disengages from the latch, it is in the fourth position. The door body 1000 can be switched between the locked and unlocked states by moving the latch 1300 to the third and fourth positions. The movement of the latch 1300 is controlled by the unlocking component 1100, which is controlled by the user or a drive mechanism.

[0079] The following explanation will be based on the example where the unlocking component 1100 is rotatable and the door 1000 is in a locked state.

[0080] Manual unlocking: The user can press the unlocking piece 1100 from front to back. The unlocking piece 1100 rotates from the first position to the second position (rotating from top to bottom with the whole facing backward). During the rotation to the second position, the unlocking piece 1100 abuts against the connecting rod 1500 (that is, during the rotation of the unlocking piece 1100, the connecting rod 1500 needs to be below the unlocking piece 1100), thereby driving the connecting rod 1500 to move. In turn, the connecting rod 1500 drives the door latches 1300 on the left and right sides to move. The door latches 1300 move from the third position to the fourth position. The door latches 1300 disengage from the latch of the machine body, and the door body 1000 switches from the locked state to the unlocked state. In this way, the door body 1000 can open the washing chamber.

[0081] Automatic unlocking: The drive mechanism 1200 drives the drive rod 1240 to move, and the guide slope 1241 abuts against the stop part 1120. As the drive rod 1240 continues to move, a component force is generated in the direction perpendicular to the direction of movement of the drive rod 1240. This causes the unlocking part 1100 to rotate backward from the first position to the second position. During the rotation to the second position, the unlocking part 1100 abuts against the connecting rod 1500, thereby causing the connecting rod 1500 to move accordingly. Then, the connecting rod 1500 drives the door latches 1300 on the left and right sides to move. The door latches 1300 move from the third position to the fourth position. The door latches 1300 disengage from the latch of the machine body, and the door body 1000 switches from the locked state to the unlocked state. Thus, the door body 1000 can open the washing chamber.

[0082] The door latch 1300 has various modes of movement, including but not limited to translation, rotation, extension, and deformation. To facilitate the engagement of the door latch 1300 with the corresponding position (latch) of the machine body, in this embodiment, the door latch 1300 is designed to be rotatable, meaning it can rotate to a third position or a fourth position. The unlocking component 1100 drives the connecting rod 1500, thereby causing the connecting rod 1500 to rotate the door latches 1300 on both sides from the third position to the fourth position. See also... Figures 1 to 8 As shown, when the door latch 1300 is in the third position, it is set horizontally. When the door latch 1300 is rotated upwards by a certain angle to reach the fourth position, the door latch 1300 is roughly tilted upwards.

[0083] To facilitate the connection between the connecting rod 1500 and the door latches 1300 on both sides, in some embodiments, the connecting rod 1500 and the door latches 1300 are connected by a plug-in joint. That is, the door latch 1300 on the left side is provided with a slot 1340, and the door latch 1300 on the right side is also provided with a slot 1340. The left end of the connecting rod 1500 is inserted into the slot 1340 of the left door latch 1300, and the right end of the connecting rod 1500 is inserted into the slot 1340 of the right door latch 1300. Since the door latches 1300 are respectively provided on the left and right sides of the door body 1000 and the door latches 1300 are rotatable, the relative distance between the door latches 1300 on the left and right sides remains unchanged. By plugging in the connection, the connection between the connecting rod 1500 and the door latches 1300 on both sides can be realized, and the door latches 1300 on both sides can also limit the movement of the connecting rod 1500, making it difficult for the connecting rod 1500 to disengage from the slot 1340. It is understandable that, since the unlocking component 1100 needs to drive the connecting rod 1500 so that the connecting rod 1500 can drive the door latch 1300 to rotate, the connecting rod 1500 needs to be misaligned with the rotation axis of the door latch 1300.

[0084] The rotatable setting of the door latch 1300 can be achieved by the following scheme: the door body 1000 includes an inner door 1001, an outer door 1002, and a second fixing block 1460. The inner door 1001 is provided with a second support seat 1420, and the door latch 1300 is provided with a second rotating shaft 1310. The second fixing block 1460 and the second support seat 1420 are connected to clamp the second rotating shaft 1310, so that the door latch 1300 can be rotatably set through the second rotating shaft 1310. Optionally, the second rotating shaft 1310 is provided with a limiting part 1320, which protrudes radially along the second rotating shaft 1310. The second rotating shaft 1310 is fixed on the second support base 1420 by at least two second fixing blocks 1460. The two second fixing blocks 1460 are a certain distance apart, so that the limiting part 1320 is located between the two second fixing blocks 1460, thus forming an axial limit on the limiting part 1320 and preventing the door latch 1300 from disengaging from the second support base 1420.

[0085] Combination Figure 9 As shown, in some embodiments, the door body 1000 further includes a third elastic member 1330, which is adapted to exert a force on the door latch 1300 to cause the door latch 1300 to tend to move from the fourth position toward the third position. That is, when the door latch 1300 moves away from the third position, the third elastic member 1330 elastically deforms and exerts a force on the door latch 1300, which forces the door latch 1300 to move toward the third position. For example, when the unlocking component 1100 moves from the first position to the second position, it drives the connecting rod 1500, which in turn drives the door latch 1300 from the third position to the fourth position. When the door latch 1300 moves to the fourth position, it disengages from the corresponding position (latch) on the machine body, allowing the door 1000 to switch to the unlocked state, thus enabling the door 1000 to open the washing chamber. At this time, the third elastic element 1330 undergoes elastic deformation and exerts force on the door latch 1300. When the unlocking component 1100 moves from the second position to the first position, the third elastic element 1330 releases its elastic potential energy, and the door latch 1300 moves to the third position under the action of the elastic force. At the same time, it drives the connecting rod 1500 to reset. The setting of the third elastic element 1330 helps the door 1000 maintain the locked state and also facilitates subsequent reset.
