Detailed implementation manners

[0040] The embodiments of the present utility model will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, in which the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present utility model and should not be construed as a limitation of the present utility model.

[0041] As Figures 1 to 3 , the door lock 10 according to an embodiment of the present utility model includes: a main body portion 11, a locking tongue 12, and a driving assembly 13. The locking tongue 12 is movably disposed in the main body portion 11 along a first direction (refer to the direction A-A in the accompanying drawings), and the driving assembly 13 is used to drive the locking tongue 12 to move. The locking tongue 12 may have a locking position and an unlocking position. In the dishwasher 100 having the door lock 10, when the locking tongue 12 is in the locking position, the door body 30 of the dishwasher 100 can be locked to the machine body 20; when the locking tongue 12 is in the unlocking position, the locking of the door body 30 can be released to facilitate opening of the door body 30. For example, in the locking position, the locking end of the locking tongue 12 can extend into the corresponding lock hole; in the unlocking position, the locking end of the locking tongue 12 will withdraw from the corresponding lock hole. The driving of the locking tongue 12 can be achieved through the driving assembly 13 so that the locking tongue 12 can move between the locking position and the unlocking position.

[0042] In addition, the main body 11 is provided with a rotating frame 111. The door lock 10 may further include a positioning member 14. The positioning member 14 is rotatably connected to the locking tongue 12 and has a first state and a second state. In the first state, the rotating frame 111 locks the positioning member 14. In the second state, the rotating frame 111 releases the locking of the positioning member 14. Thus, through the cooperation of the positioning member 14 and the rotating frame 111, the locking and unlocking of the positioning member 14 can be achieved. Among them, when the positioning member 14 is locked, the locking tongue 12 is also locked, so as to maintain the state of the locking tongue 12; when the positioning member 14 is unlocked, the locking of the locking tongue 12 is also released, so as to facilitate the displacement of the locking tongue 12.

[0043] According to the door lock 10 of the embodiment of the present invention, the cooperation of the rotating frame 111 and the positioning member 14 can be used to lock and unlock the positioning member 14, and the state of the locking tongue 12 can be maintained.

[0044] Among them, the locking tongue 12 of the present invention may be provided with a mounting hole 101, and the positioning member 14 may be rotatably inserted through the mounting hole 101. The locking tongue 12 in the present invention may be set as a bolt structure. When the locking tongue 12 is in the retracted position, the locking tongue 12 will move out of the locking position to the unlocking position. When the locking tongue 12 is in the extended position, the locking tongue 12 will move to the locking position; in addition, the locking tongue 12 may also be set as a hook shape. When the locking tongue 12 is in the retracted position, the locking tongue 12 will move to the locking position. When the locking tongue 12 is in the extended position, the locking tongue 12 will move out of the locking position to the unlocking position. Of course, the locking tongue 12 in the present invention may also be set in other forms.

[0045] Such as Figure 7 and Figure 8 , in some embodiments, the rotating frame 111 is provided with a first groove portion 1021 and a second groove portion 1022. The first groove portion 1021 and the second groove portion 1022 are distributed along a first direction, and the first groove portion 1021 and the second groove portion 1022 are communicated with each other. The positioning member 14 includes a positioning portion 1483 inserted through the rotating frame 111. Among them, in the first state, the positioning portion 1483 is limited in the first groove portion 1021; in the second state, the positioning portion 1483 is slidable between the first groove portion 1021 and the second groove portion 1022. It can facilitate the locking and unlocking of the positioning member 14 and simplify the structure of the door lock 10.

[0046] Optionally, in some examples, the first groove portion 1021 is farther from the locking end of the locking tongue 12 than the second groove portion 1022. That is to say, when the positioning portion 1483 is limited in the first groove portion 1021, the locking end of the locking tongue 12 is in the retracted state; when the positioning portion 1483 is slidable between the first groove portion 1021 and the second groove portion 1022, the locking tongue 12 will switch between the retracted state and the extended state. Among them, the driving assembly 13 may include an elastic member 131 and a driving member 132, wherein the elastic member 131 may be arranged to elastically push the locking tongue 12 to extend; and the driving member 132 may be arranged to drive the locking tongue 12 to retract.

[0047] In addition, in some other examples, it can also be set that the first groove portion 1021 is closer to the locking end of the locking tongue 12 than the second groove portion 1022. In this way, the locking or unlocking situation when the locking tongue 12 extends or retracts is opposite to that of the foregoing embodiment. Among them, the driving assembly 13 may include an elastic member 131 and a driving member 132, wherein the elastic member 131 may be arranged to elastically push the locking tongue 12 to retract; and the driving member 132 may be arranged to drive the locking tongue 12 to extend.

[0048] Optionally, the positioning portion 1483 is rotatable within the first groove portion 1021. Thereby, it is convenient to adjust the state of the positioning portion 1483 within the first groove portion 1021, so as to realize the switching of the positioning member 14 between the first state and the second state, quickly lock and unlock the positioning member 14, and further quickly unlock and lock the locking tongue 12.

[0049] In some embodiments, in the projection on the normal plane of the first direction (or the plane perpendicular to the first direction), the dimension s1 of the first groove portion 1021 along the second direction (refer to the direction B-B in the attached drawing) is greater than the dimension s2 of the second groove portion 1022 along the second direction, and the second direction is perpendicular to the first direction.

[0050] Among them, referring to the attached Figure 10 , in the first state, the dimension s3 of the positioning portion 1483 along the second direction is less than or equal to the dimension s1 of the first groove portion 1021 and greater than the dimension s2 of the second groove portion 1022. When the positioning member 14 is in the first state, the positioning portion 1483 may be located within the first groove portion 1021, and since the dimension of the positioning portion 1483 in the second direction is greater than the dimension of the second groove portion 1022 in the second direction, the positioning portion 1483 cannot enter the second groove portion 1022, thereby realizing the effective positioning of the positioning portion 1483 within the first groove portion 1021 and improving the stable locking of the positioning member 14.

[0051] In addition, referring to the attached Figure 7, in the second state, the dimension of the positioning portion 1483 in the second direction is less than or equal to the dimension s2 of the second groove portion 1022. The dimension of the positioning portion 1483 in the second direction is less than that of the first groove portion 1021 and the second groove portion 1022. The positioning member 14 can slide between the first groove portion 1021 and the second groove portion 1022, thereby releasing the locking of the positioning member 14. By rotating the positioning portion 1483, the dimension of the positioning portion 1483 in the second direction can be changed, and then the state of the positioning member 14 can be adjusted. Through the dimension cooperation with the first groove portion 1021 and the second groove portion 1022, the locking and unlocking of the positioning member 14 are realized.

[0052] Combined with the foregoing, the positioning member 14 can be switched between the first state and the second state by rotation. In some embodiments, a guiding structure is provided in the first groove portion 1021. The guiding structure is used to guide the positioning member 14 to rotate between the first state and the second state when the positioning member 14 moves in the first direction. Through the guiding of the guiding portion, the movement of the positioning member 14 in the first direction can be converted into the rotation of the positioning member 14, so that the positioning member 14 can be conveniently switched between the second state and the first state, facilitating the opening and closing of the door lock 10.

[0053] Among them, the guiding structure of the present invention can be set in an eccentric form, that is to say, the guiding structure is offset from the rotation center axis L of the positioning member 14. In this way, when the positioning member 14 moves in the first direction, the guiding structure can be used to drive the positioning member 14 to rotate.

[0054] Optionally, the guiding structure includes a first guiding portion 1023 and a second guiding portion 1024. In the projection on the normal plane of the first direction, the first guiding portion 1023 and the second guiding portion 1024 are respectively arranged on opposite sides of the rotation center axis L of the positioning member 14, and the distance between the first guiding portion 1023 and the second groove portion 1022 is greater than the distance between the second guiding portion 1024 and the second groove portion 1022. Through the cooperation of the first guiding portion 1023 and the second guiding portion 1024, the rotation of the positioning member 14 can be stably driven, the structure of the door lock 10 is simplified, and the stable rotation of the positioning member 14 is ensured, facilitating the switching of the positioning member 14 between the first state and the second state.

[0055] In some embodiments, combined with Figures 5 to 8, the positioning part 1483 is provided with a first half part 141 and a second half part 142 along the thickness direction. The two side surfaces of the first half part 141 along the width direction are set as first guiding surfaces 143 that gradually contract from the first half part 141 to the second half part 142; the two side surfaces of the second half part 142 along the width direction are set as second guiding surfaces 144 that gradually contract from the second half part 142 to the first half part 141. The first guiding surface 143, the second guiding surface 144, the first guiding part 1023 and the second guiding part 1024 cooperate to guide the positioning member 14 to rotate between the first state and the second state. Through the inclined settings of the first guiding surface 143 and the second guiding surface 144, when the first guiding surface 143 cooperates with the first guiding part 1023, the second guiding surface 144 cooperates with the first guiding part 1023, the first guiding surface 143 cooperates with the second guiding part 1024, or the second guiding surface 144 cooperates with the second guiding part 1024, the inclined guiding surfaces can be used to convert the translational movement of the positioning member 14 in the first direction into the rotational movement of the positioning member 14 around the rotation center axis L, thereby simplifying the structure of the door lock 10 and improving the stability of the door lock 10.

[0056] Wherein, in the projection on the normal plane of the first direction, the distance L1 between the first guiding part 1023 and the rotation center axis L of the positioning member 14 is less than the thickness dimension L3 of the first half part 141, and the distance between the first guiding part 1023 and the rotation center axis L of the positioning member 14 is less than the thickness dimension L4 of the second half part 142. When the positioning member 14 in the second state moves in the first direction, the first half part 141 can be opposite to the first guiding part 1023, so as to drive the positioning member 14 to rotate by using the first guiding part 1023.

[0057] In the projection on the normal plane of the first direction, the distance L2 between the second guiding part 1024 and the rotation center axis L of the positioning member 14 is greater than the thickness dimension L3 of the first half part 141, and the distance between the second guiding part 1024 and the rotation center axis L of the positioning member 14 is greater than the thickness dimension L4 of the second half part 142. When the positioning member 14 in the second state moves in the first direction, the second guiding part 1024 is staggered from the positioning member 14, which is convenient for the positioning member 14 in the second state to move in the first direction. In addition, the distance L2 between the second guiding part 1024 and the rotation center axis L of the positioning member 14 is less than the width dimension L5 of the first half part 141, and the distance L2 between the second guiding part 1024 and the rotation center axis L of the positioning member 14 is less than the width dimension L6 of the second half part 142, which can use the limiting effect of the second guiding part 1024 to maintain the first state of the positioning member 14, and can also drive the positioning member 14 to rotate when the positioning member 14 switches from the first state to the second state.

[0058] Optionally, the thickness dimension of the first half part 141 is the same as that of the second half part 142. Further, the first half part 141 and the second half part 142 are symmetrical. The structure of the positioning member 14 can be simplified, and the stable driving of the rotation of the positioning member 14 by the guiding structure can be achieved. Of course, in the present utility model, the thickness dimensions of the first half part 141 and the second half part 142 may also be different.

[0059] In some embodiments, the diagonal dimension L9 of the positioning portion 1483 is less than or equal to the dimension s1 of the first groove portion 1021 in the second direction, so that the positioning portion 1483 can be conveniently rotated within the first groove portion 1021, improving the stability of the rotation of the positioning member 14 and facilitating the rotation of the positioning member 14 between the second state and the first state. Additionally, the distance between the first guiding portion 1023 and the second guiding portion 1024 can also be set to be greater than the width dimension of the positioning portion 1483.

[0060] In some embodiments, the thickness dimension L7 of the positioning portion 1483 is less than or equal to the dimension s2 of the second groove portion 1022 in the second direction, the width dimension of the positioning portion 1483 is less than or equal to the dimension s1 of the first groove portion 1021 in the second direction and greater than the dimension s2 of the second groove portion 1022 in the second direction, and the second direction is perpendicular to the first direction. The structure of the positioning member 14 can be simplified, and the stability of the positioning member 14 in the first state and the second state can be maintained.

[0061] In some embodiments, in the first state, the first guiding surface 143 on one side of the first half part 141 in the width direction abuts against the second guiding portion 1024 in the first direction, and the end surface on the other side faces the first guiding portion 1023 in the first direction, and the two ends of the second half part 142 in the width direction respectively abut against the two side surfaces of the first groove portion 1021. Or, in the first state, the first guiding surface 143 on one side of the second half part 142 in the width direction abuts against the second guiding portion 1024 in the first direction, and the end surface on the other side faces the first guiding portion 1023 in the first direction, and the two ends of the first half part 141 in the width direction respectively abut against the two side surfaces of the first groove portion 1021. Or, in the second state, one of the first half part 141 and the second half part 142 faces the first guiding portion 1023 in the first direction, and the other is offset from the first guiding portion 1023 in the first direction.

[0062] Specifically, as Figures 7 to 15 shows a schematic diagram of the cooperation between the positioning member 14 and the rotating frame 111 in the door lock 10 according to an embodiment of the present utility model.

[0063] As Figure 7 , the positioning member 14 is in the second state, at least a part of the positioning portion 1483 is disposed in the second groove portion 1022, and can move between the first groove portion 1021 and the second groove portion 1022 in the first direction. At this time, the lock tongue 12 extends to the locked position.

[0064] As Figure 8 , when the positioning member 14 needs to be switched to the first state, the positioning member 14 moves downward (referring to the downward direction along the paper surface in the attached Figures 7 to 15 ), when the first half portion 141 of the positioning member 14 moves to the second groove portion 1022, the first guiding surface 143 of the first half portion 141 contacts the first guiding portion 1023.

[0065] As Figure 9 , when the positioning member 14 continues to move downward, the first guiding portion 1023 cooperates with the first guiding surface 143, which will guide the positioning member 14 to rotate. When the positioning member 14 rotates by a certain angle, the second half portion 142 and the second guiding portion 1024 are opposite to each other in the up and down direction.

[0066] As Figure 10 , when the positioning member 14 moves upward, the second guiding portion 1024 will contact the second guiding surface 144 of the second half portion 142. The upward movement of the positioning member 14 will be converted into a rotational movement, thereby causing the positioning member 14 to rotate to the first state, realizing the switching from the second state to the first state. When the positioning member 14 is in the second state, at least a part of the positioning portion 1483 is provided in the first groove portion 1021 and is limited in the first groove portion 1021. At this time, the locking tongue 12 extends to the unlocked position.

[0067] As Figure 11 , when the positioning member 14 needs to be rotated to the second state, the positioning member 14 moves downward (referring to the downward direction along the paper surface in the attached Figures 7 to 15 ), and the end surface of the second half portion 142 will contact the first guiding portion 1023.

[0068] As Figure 12 , when the positioning member 14 continues to move downward, the cooperation between the end surface of the second half portion 142 and the first guiding portion 1023 converts the downward movement of the positioning member 14 into the rotation of the positioning member 14, thereby causing the positioning member 14 to flip. When the positioning member 14 rotates by a predetermined angle, the end surface of the first half portion 141 corresponds to the second guiding portion 1024 along the first direction.

[0069] As Figure 13 , when the positioning member 14 moves upward, the end surface of the first half portion 141 will contact the second guiding portion 1024.

[0070] As Figure 14 , when the positioning member 14 continues to move upward, the cooperation between the end surface of the first half portion 141 and the second guiding portion 1024 converts the upward movement of the positioning member 14 into the rotation of the positioning member 14, thereby causing the positioning member 14 to flip. When the positioning member 14 rotates by a predetermined angle, the positioning member 14 is switched to the second state and can move between the first groove portion 1021 and the second groove portion 1022 along the first direction.

[0071] As Figure 15 shown in Figure 15 , when the positioning member 14 is in the second state, at least a part of the positioning member 14 is disposed in the second groove portion 1022 and can move between the first groove portion 1021 and the second groove portion 1022 in the first direction. At this time, the locking tongue 12 extends out and is in the locked position.

[0072] As Figure 3 shown in Figure 3 , in some embodiments, the locking tongue 12 has a first slider 121 and a second slider 122 spaced apart in the third direction. The rotating frame 111 is disposed between the first slider 121 and the second slider 122. The positioning member 14 passes through the first slider 121, the second slider 122, and the rotating frame 111. The third direction is perpendicular to the first direction. This can facilitate the cooperation between the locking tongue 12 and the main body portion 11, realize the stable movement of the locking tongue 12 between the unlocked position and the locked position, and ensure the stable cooperation between the positioning member 14 and the rotating frame 111 and the locking tongue 12.

[0073] Among them, as Figures 4 to 6 shown in Figures 4 to 6 , the positioning member 14 includes a first rotating portion 1482, a second rotating portion 1484, and a positioning portion 1483. The positioning portion 1483 is connected between the first rotating portion 1482 and the second rotating portion 1484. The positioning portion 1483 passes through the rotating frame 111. The first rotating portion 1482 passes through the first slider 121. The second rotating portion 1484 passes through the second slider 122. In addition, the positioning member 14 further includes a limiting portion 1481. The limiting portion 1481, the first rotating portion 1482, the positioning portion 1483, and the second rotating portion 1484 are sequentially connected along the rotation center axis L of the positioning member 14. Combining the foregoing, the positioning portion 1483 includes the aforementioned first half portion 141 and second half portion 142. Among them, the radial dimension of the positioning portion 1483 can be set to be greater than the radial dimensions of the first rotating portion 1482, the transmission portion 1483, and the second rotating portion 1484.

[0074] Optionally, as Figure 3 shown in Figure 3 , the main body portion 11 is further provided with a sliding track 114. The locking tongue 12 is slidably disposed in the sliding track 114 in the first direction. The rotating frame 111 is disposed inside the sliding track 114. This can improve the stability of the locking tongue 12 sliding in the first direction, avoid or reduce the sway of the locking tongue 12 around a direction deviating from the first direction. In addition, combining the foregoing embodiments, through guiding, it can facilitate the positioning member 14 to move along a stable trajectory, so as to facilitate converting the movement of the positioning member 14 in the first direction into a rotational movement, and improve the stability of the door lock 10.

[0075] As Figures 1 to 3, in some embodiments, the driving assembly 13 includes an elastic member 131 and a driving member 132. The elastic member 131 applies an elastic force to the locking tongue 12 in the first direction. The driving member 132 is in transmission connection with the locking tongue 12 and is configured to drive the locking tongue 12 to move in a direction opposite to the elastic force against the elastic force.

[0076] For example, the elastic member 131 applies an elastic force to the locking tongue 12 in the first direction to extend out of the main body portion 11, and the driving member 132 can drive the locking tongue 12 to move in the direction of retracting into the main body portion 11 in the first direction; alternatively, the elastic member 131 applies an elastic force to the locking tongue 12 in the first direction to retract into the main body portion 11, and the driving member 132 can drive the locking tongue 12 to move in the direction of extending out of the main body portion 11 in the first direction.

[0077] Optionally, the elastic member 131 is disposed between the locking tongue 12 and the main body portion 11 in the first direction and is configured to apply an elastic force to the locking tongue 12 to extend in the first direction. In this way, the driving member 132 can be used to drive the locking tongue 12 to retract, and the elastic member 131 can be used to drive the locking tongue 12 to extend. When the locking tongue 12 is in the extended state and the driving member 132 loses power, under the action of the elastic force of the elastic member 131, the locking tongue 12 can be driven to maintain the extended state, thereby facilitating the locking tongue 12 to be maintained in the locked position, maintaining the stability of the cooking device, and avoiding scalding.

[0078] Optionally, the locking tongue 12 is provided with a mating portion 123, the mating portion 123 is provided with an iron core 146, the driving member 132 includes a solenoid valve 1321 and a magnetic core 1322, and the magnetic core 1322 and the iron core 146 are opposite in the first direction. It can facilitate the retraction of the locking tongue 12, simplify the driving assembly 13 of the locking tongue 12, simplify the structure of the door lock 10, thereby improving the stability of the door lock 10 and reducing the failure rate.

[0079] The utility model is a clever transmission mechanical structure, which realizes the locking and unlocking states of the door lock. A locking tongue and a rotating frame are arranged inside the door lock. The positioning member is assembled on the locking tongue and can rotate freely. The locking tongue moves linearly in the sliding track. When the locking tongue moves linearly in the sliding track, the rotating positioning member will rotate under the action of the rotating frame. Two stable and fixed states will appear during the rotation process, which can fix the locking tongue in the locked and unlocked conditions.

[0080] An elastic member (such as a spring) is arranged at the end of the locking tongue to have an elastic thrust force always outward. Similarly, a solenoid valve (not limited to the solenoid valve, and other driving structures can also be used) is arranged inside the door lock, and an iron core is arranged inside the locking tongue. When the solenoid valve acts, a short-term attraction force is applied to the locking tongue, so that the locking tongue moves in the sliding track, thereby driving the positioning member to rotate.
