Description

Technical Field

[0001] The present application relates to the technical field of dishwashers, and in particular to a door lock device. Background Art

[0002] The main action of the household dishwasher door lock is: when the door is closed, the tension spring force and the inertial impact force of the door body are used to stimulate the relevant structure of the door lock. Under the action of the door lock spring, the door body is buckled and pulled toward the dishwasher, so that the door body can press the sealing ring on the dishwasher to seal the dishwasher. This means that compared with conventional equipment, the number of times the dishwasher door lock is opened and closed in one use is more than that of conventional washing machines, electric ovens and other equipment. As a result, the stability requirements for the door lock will be higher to prevent the door lock from being damaged during long-term and high-intensity use.

[0003] The door locks in the prior art are difficult to meet the multi-frequency requirements of long-term use due to their complex structure and insufficient structural stability. The locks are prone to break after a few years of use. When the door locks are damaged, water vapor is prone to overflow, affecting the user experience and even threatening user safety. Utility Model Content

[0004] Based on this, it is necessary to provide a door lock device to solve the above problems in the existing dishwasher door lock.

[0005] The door lock device provided in the present application is applied to a dishwasher. The door lock device is arranged between the inner tank and the door body of the dishwasher. The door lock device includes a lock assembly and a transmission assembly.

[0006] The lock assembly comprises a first lock and a second lock, wherein the first lock is mounted on the door body, and the second lock is rotatably disposed on the inner container, and the door body can rotate relative to the inner container and form at least a first position and a second position;

[0007] The transmission assembly is movably arranged on the inner container, and the transmission assembly is in transmission connection with the second lock;

[0008] When the door body rotates to the first position, the first lock is engaged with the second lock; when the transmission assembly is triggered to move relative to the inner container to drive the second lock to rotate relative to the inner container, the second lock is disengaged from the first lock, and the door body can be rotated from the first position to the second position.

[0009] The door lock device disclosed in the present application can be engaged with a first lock catch and a second lock catch. When the door body rotates to a first position relative to the inner shell, the first lock catch on the door body engages with the second lock catch on the inner shell, so that the door body is fixed on the inner shell. At this time, the door body is in a closed state. The transmission component is movably arranged on the inner shell. When an external force triggers the transmission component to move relative to the inner shell, the movement of the transmission component can drive the second lock catch to rotate relative to the inner shell, so that the second lock catch is disengaged from the first lock catch. At this time, the door body can be rotated from the first position to the second position. At this time, the door body is in an open state. The door lock device of the present application can realize rapid switching of the door body between the closed and opened states through the cooperation of the lock catch component and the transmission component. In addition, the transmission component can be triggered to move manually, thereby driving the second lock catch away from the first lock catch, thereby realizing disengagement. The structure is simple and reliable.

[0010] In one embodiment, the transmission assembly includes a traction member and a rotating mechanism, the rotating mechanism is arranged on the inner liner, the two ends of the traction member are respectively connected to the rotating mechanism and the second lock, and the transmission assembly rotates to drive the traction member to move to trigger the second lock to move away from the first lock.

[0011] The door lock device in the above embodiment further defines that the two ends of the traction member are respectively connected to the rotating mechanism and the second lock buckle. When the rotating mechanism rotates relative to the inner liner, the rotating mechanism can drive the traction member to move relative to the inner liner, thereby driving the second lock buckle to rotate in a direction away from the first lock buckle, thereby achieving the first lock buckle being disengaged from the second lock buckle.

[0012] In one embodiment, the rotating mechanism includes a button module, a transmission rod and a swing arm which are sequentially connected in transmission. The button module is movably arranged on the inner liner. The button module is pressed relative to the inner liner to trigger the transmission rod to rotate. The rotation of the transmission rod drives the swing arm to rotate to trigger the second lock to move away from the first lock.

[0013] The door lock device in the above embodiment further defines that the key module, the transmission rod and the swing arm are sequentially connected in transmission. When the key module moves relative to the inner shell after being pressed, the key module drives the swing arm to rotate through the transmission rod, so that the traction member connected to the swing arm moves relative to the inner shell, thereby moving the second lock buckle in a direction away from the first lock buckle; by arranging the swing arm between the transmission rod and the traction member, the length of the power arm applied to the traction member is extended, so that the second lock buckle can be moved in a direction away from the first lock buckle through the traction member with a smaller power.

[0014] In one embodiment, the button module includes a manual button and a transmission member, the manual button is movably arranged on the inner tank, the transmission member is arranged on the transmission rod, the transmission member is transmission-connected to the transmission rod, the manual button is at least partially located above the transmission member, and when the manual button is pressed, the manual button abuts against the transmission member, and the transmission member drives the transmission rod to rotate.

[0015] The door lock device in the above embodiment further defines that the manual button is movably arranged on the inner shell, and the manual button can be displaced relative to the inner shell by manually pressing it. The manual button is connected to the transmission rod through a transmission member, and at least a part of the manual button is arranged above the transmission member. When the manual button is pressed, the manual button abuts against the transmission member, and the transmission member is driven by the force of the manual button to drive the transmission rod to rotate relative to the inner shell. Through the cooperation of the manual button, the transmission member and the transmission rod, it can be ensured that after the manual button is pressed, the traction member can be driven to move relative to the inner shell through the transmission member, the transmission rod and the swing arm in sequence, and then the traction member pulls the second lock buckle in the direction away from the first lock buckle.

[0016] In one embodiment, the button module also includes a first torsion spring, which is fixedly mounted on the manual button or the inner shell, one end of the first torsion spring is connected to the manual button, and the other end is connected to the inner shell, and the first torsion spring is used to reset the manual button after being pressed relative to the inner shell.

[0017] The door lock device in the above embodiment further limits that the first torsion spring can be fixedly installed on the manual button, and the hooks at both ends of the first torsion spring are respectively connected to the manual button and the inner liner. When the manual button is pressed, the first torsion spring undergoes elastic deformation and the elastic potential energy increases. When the pressure on the manual button is released, the first torsion spring overcomes the gravity of the manual button and returns to its original position.

[0018] In one of the embodiments, the cross-section of the transmission rod is polygonal, the transmission member and the swing arm are formed with through holes adapted to the shape of the transmission rod, and the transmission rod is respectively inserted into the through holes of the transmission rod and the swing arm.

[0019] The door lock device in the above embodiment further defines that the cross-section of the transmission rod is polygonal, and the transmission member and the swing arm are connected to the corners on the transmission rod through the corners in the through hole, thereby simplifying the structure of the transmission member, the swing arm and the transmission rod to achieve transmission connection, and the structure is reliable and the implementation cost is low.

[0020] In one embodiment, the second lock buckle is distributed on the side wall of the inner container, the swing arm is located above the second lock buckle and the swing arm can swing back and forth relative to the side wall of the inner container.

[0021] The door lock device in the above embodiment further defines that the second lock buckle is distributed on the side wall of the inner container, the swing arm is located above the second lock buckle, and the traction rod is arranged between the swing arm and the second lock buckle. The swing arm can swing back and forth relative to the side wall of the inner container under the cooperation of the manual button, the transmission member and the transmission rod. Specifically, when the swing arm swings forward relative to the side wall of the inner container, the swing arm drives the traction member to move, so that the second lock buckle rotates relative to the inner container in a direction away from the first lock buckle.

[0022] In one embodiment, the traction member is a pull rope or a pull rod, and rings are respectively provided at both ends of the traction member. The rings at both ends of the traction member are respectively mounted on the first column on the second lock buckle and the second column on the rotating mechanism.

[0023] In one embodiment, the door lock device in the above embodiment further defines that the lock assembly also includes a second torsion spring, the second torsion spring is fixedly mounted on the second lock or the inner liner, one end of the second torsion spring is connected to the second lock, and the other end is connected to the inner liner, and the second torsion spring is used to reset the second lock after it is disengaged from the first lock.

[0024] The door lock device in the above embodiment further defines that the second torsion spring can be fixedly mounted on the second lock buckle, and the hooks at both ends of the second torsion spring are respectively connected to the second lock buckle and the inner shell. When the manual button is pressed, the traction member pulls the second lock buckle to rotate relative to the inner shell in a direction away from the first lock buckle, so that the first lock buckle is disengaged from the second lock buckle. At this time, the second torsion spring undergoes elastic deformation and the elastic potential energy increases. When the force acting on the manual button is cancelled, the second torsion spring drives the second lock buckle to return to its original position under the action of the elastic potential energy; and when the first lock buckle and the second lock buckle are engaged, the second torsion spring ensures the stability of the engagement of the first lock buckle and the second lock buckle to a certain extent, and it is not easy to accidentally disengage by itself.

[0025] In one of the embodiments, a limit baffle is provided at the second lock buckle of the inner liner, and when the second lock buckle is engaged with the first lock buckle, the second lock buckle abuts against the limit baffle.

[0026] In one embodiment, the door lock device also includes a micro switch, which is arranged on the inner shell, and a transition pendulum is arranged between the first lock buckle and the micro switch, and the transition pendulum is rotatably arranged on the inner shell, and the contact of the micro switch is arranged opposite to the transition pendulum. When the door body is in the first position, the first lock buckle pushes the transition pendulum to rotate to squeeze the contact of the micro switch, and the micro switch is used to detect the opening and closing state of the door body.

[0027] The door lock device in the above embodiment is provided with a micro switch on the inner tank. When the door body is in a closed state, the first lock catch and the contacts of the micro switch are in a relatively set positional relationship. By providing a transition pendulum that can rotate on the inner tank between the first lock catch and the micro switch, when the door body gradually moves from the second position to the first position, the first lock catch pushes the transition pendulum to rotate, and then the transition pendulum presses the contacts of the micro switch, and then the micro switch outputs a signal confirming that the door body has completed the closing operation, so that the dishwasher can only carry out the cleaning task when it is confirmed that the door is closed, thereby improving the safety performance of the dishwasher.

[0041] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0042] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so as to describe the embodiments of the present application described herein.

[0043] like Figures 1 to 6 As shown, this embodiment provides a door lock device, which is applied to a dishwasher. The door lock device is arranged between the inner tank 2 and the door body 3 of the dishwasher. The door lock device includes:

[0044] The lock assembly 10 includes a first lock 11 and a second lock 12. The first lock 11 is mounted on the door body 3, and the second lock 12 is rotatably disposed on the inner liner 2. The door body 3 can rotate relative to the inner liner 2 and form at least a first position and a second position.

[0045] A transmission assembly 20, which is movably disposed on the inner liner 2 and is in transmission connection with the second lock buckle 12;

[0046] When the door body 3 rotates to the first position, the first lock buckle 11 is engaged with the second lock buckle 12; when the trigger transmission assembly 20 moves relative to the inner liner 2 to drive the second lock buckle 12 to rotate relative to the inner liner 2, the second lock buckle 12 is disengaged from the first lock buckle 11, and the door body 3 can be rotated from the first position to the second position.

[0047] The door lock device disclosed in the present application can be engaged with the first lock catch 11 and the second lock catch 12. When the door body 3 rotates to the first position relative to the inner shell 2, the first lock catch 11 on the door body 3 is engaged with the second lock catch 12 on the inner shell 2, so that the door body 3 is fixed on the inner shell 2. At this time, the door body 3 is in a closed state. The transmission component 20 is movably arranged on the inner shell 2. When an external force triggers the transmission component 20 to move relative to the inner shell 2, the transmission component 20 can drive the second lock catch 12 to rotate relative to the inner shell 2 when it moves, so that the second lock catch 12 is disengaged from the first lock catch 11. At this time, the door body 3 can be rotated from the first position to the second position. At this time, the door body 3 is in an open state. The door lock device of the present application realizes the rapid switching of the door body 3 between the closed and opened states through the cooperation of the lock catch component 10 and the transmission component 20, and the transmission component 20 can be triggered to move manually, thereby driving the second lock catch 12 away from the first lock catch 11, thereby achieving disengagement. The structure is simple and reliable.

[0048] like Figure 1 , 3 As shown in Figures 4 and 6, in addition to the features of the above embodiments, this embodiment further defines that: the transmission assembly 20 includes a traction member 22 and a rotating mechanism 210, the rotating mechanism 210 is arranged on the inner liner 2, and the two ends of the traction member 22 are respectively connected to the rotating mechanism 210 and the second lock buckle 12, and the transmission assembly 20 rotates to drive the traction member 22 to move to trigger the second lock buckle 12 to move in a direction away from the first lock buckle 11.

[0049] The two ends of the traction member 22 are respectively connected to the rotating mechanism 210 and the second lock buckle 12. When the rotating mechanism 210 rotates relative to the inner liner 2, the rotating mechanism 210 can drive the traction member 22 to move relative to the inner liner 2, thereby driving the second lock buckle 12 to rotate in a direction away from the first lock buckle 11, thereby achieving the first lock buckle 11 being disengaged from the second lock buckle 12. Specifically, the rotating mechanism 210, the traction member 22 and the second lock buckle 12 are sequentially distributed from top to bottom along the height direction of the inner liner 2. When the rotating mechanism 210 rotates, the traction member 22 pulls in the direction of the rotating mechanism 210, thereby dragging the second lock buckle 12 to rotate in the direction of the rotating mechanism 210.

[0050] like Figure 1 , 3 As shown in Figures 4 and 6, in addition to the features of the above embodiments, the present embodiment further defines that: the rotating mechanism 210 includes a button module 211, a transmission rod 212 and a swing arm 213 which are sequentially connected in transmission, the button module 211 is movably arranged on the inner liner 2, the button module 211 is pressed relative to the inner liner 2 to trigger the transmission rod 212 to rotate, and the rotation of the transmission rod 212 drives the swing arm 213 to rotate to trigger the second lock buckle 12 to move away from the first lock buckle 11.

[0051] Among them, the button module 211, the transmission rod 212 and the swing arm 213 are connected in sequence. When the button module 211 moves relative to the inner liner 2 after being pressed, the button module 211 drives the swing arm 213 to rotate through the transmission rod 212, so that the traction member 22 connected to the swing arm 213 moves relative to the inner liner 2, thereby moving the second lock buckle 12 away from the first lock buckle 11; by arranging the swing arm 213 between the transmission rod 212 and the traction member 22, relative to extending the length of the power arm applied to the traction member 22, it is possible to use a smaller power to move the second lock buckle 12 away from the first lock buckle 11 through the traction member 22.

[0052] like Figure 1 , 3 As shown in Figures 4 and 6, in addition to the features of the above embodiments, this embodiment further defines that: the button module 211 includes a manual button 2111 and a transmission member 2112, the manual button 2111 is movably arranged on the inner liner 2, the transmission member 2112 is arranged on the transmission rod 212, the transmission member 2112 is transmission-connected to the transmission rod 212, the manual button 2111 is at least partially located above the transmission member 2112, when the manual button 2111 is pressed, the manual button 2111 abuts against the transmission member 2112, and the transmission member 2112 drives the transmission rod 212 to rotate.

[0053] Among them, the manual button 2111 is movably arranged on the inner liner 2, and the manual button 2111 can be displaced relative to the inner liner 2 by manually pressing. It is connected to the transmission rod 212 through the transmission member 2112, and at least a part of the manual button 2111 is arranged above the transmission member 2112. When the manual button 2111 is pressed, the manual button 2111 abuts against the transmission member 2112, and the transmission member 2112 is driven by the force of the manual button 2111 to drive the transmission rod 212 to rotate relative to the inner liner 2. Through the cooperation of the manual button 2111, the transmission member 2112 and the transmission rod 212, it can be ensured that after the manual button 2111 is pressed, the traction member 22 can be driven to move relative to the inner liner 2 through the transmission member 2112, the transmission rod 212 and the swing arm 213 in sequence, and then the traction member 22 pulls the second lock buckle 12 in the direction away from the first lock buckle 11.

[0054] like Figure 3 and Figure 6 As shown, in addition to the features of the above-mentioned embodiments, this embodiment further defines: the button module 211 also includes a first torsion spring 2113, the first torsion spring 2113 is fixedly mounted on the manual button 2111 or the inner liner 2, one end of the first torsion spring 2113 is connected to the manual button 2111, and the other end is connected to the inner liner 2, and the first torsion spring 2113 is used to reset the manual button 2111 after being pressed relative to the inner liner 2.

[0055] Among them, the first torsion spring 2113 can be fixedly installed on the manual button 2111, and the hooks at both ends of the first torsion spring 2113 are respectively connected to the manual button 2111 and the inner liner 2. When the manual button 2111 is pressed, the first torsion spring 2113 undergoes elastic deformation and the elastic potential energy increases. When the pressure on the manual button 2111 is released, the first torsion spring 2113 overcomes the gravity of the manual button 2111 and returns to its original position.

[0056] like Figure 1 and Figure 3 As shown, in addition to the features of the above-mentioned embodiments, this embodiment further defines that: the cross-section of the transmission rod 212 is polygonal, the transmission member 2112 and the swing arm 213 are formed with through holes that are adapted to the shape of the transmission rod 212, and the transmission rod 212 is respectively inserted into the through holes of the transmission rod 212 and the swing arm 213.

[0057] Among them, the cross-section of the transmission rod 212 is polygonal, and the transmission member 2112 and the swing arm 213 are connected to the corners on the transmission rod 212 through the corners in the through hole, which simplifies the structure of the transmission member 2112, the swing arm 213 and the transmission rod 212 to achieve transmission connection. The structure is reliable and the implementation cost is low.

[0058] like Figure 1 and Figure 4 As shown, in addition to the features of the above embodiments, this embodiment further defines that: the second lock buckle 12 is distributed on the side wall of the inner liner 2, the swing arm 213 is located above the second lock buckle 12 and the swing arm 213 can swing back and forth relative to the side wall of the inner liner 2.

[0059] Among them, the second lock buckle 12 is distributed on the side wall of the inner liner 2, the swing arm 213 is located above the second lock buckle 12, and the traction rod is arranged between the swing arm 213 and the second lock buckle 12. The swing arm 213 can swing back and forth relative to the side wall of the inner liner 2 under the cooperation of the manual button 2111, the transmission member 2112 and the transmission rod 212. Specifically, when the swing arm 213 swings forward relative to the side wall of the inner liner 2, the swing arm 213 drives the traction member 22 to move, so that the second lock buckle 12 rotates relative to the inner liner 2 in a direction away from the first lock buckle 11.

[0060] In addition to the features of the above embodiments, this embodiment further defines that: the traction member 22 is a pull rope or a pull rod, and rings 221 are respectively provided at both ends of the traction member 22, and the rings 221 at both ends of the traction member 22 are respectively mounted on the first column 121 on the second lock buckle 12 and the second column 2131 on the rotating mechanism 210.

[0061] like Figure 4 , 5As shown in Figures 6 and 7, in addition to the features of the above embodiments, the present embodiment further defines that: the lock assembly 10 also includes a second torsion spring 13, the second torsion spring 13 is fixedly mounted on the second lock 12 or the inner liner 2, one end of the second torsion spring 13 is connected to the second lock 12, and the other end is connected to the inner liner 2, and the second torsion spring 13 is used to reset the second lock 12 after it is disengaged from the first lock 11.

[0062] Among them, the second torsion spring 13 can be fixedly installed on the second lock buckle 12, and the hooks at both ends of the second torsion spring 13 are respectively connected to the second lock buckle 12 and the inner liner 2. When the manual button 2111 is pressed, the traction member 22 pulls the second lock buckle 12 to rotate relative to the inner liner 2 in a direction away from the first lock buckle 11, so that the first lock buckle 11 is disengaged from the second lock buckle 12. At this time, the second torsion spring 13 undergoes elastic deformation and the elastic potential energy increases. When the force acting on the manual button 2111 is removed, the second torsion spring 13 drives the second lock buckle 12 to return to its original position under the action of the elastic potential energy; and when the first lock buckle 11 and the second lock buckle 12 are engaged, the second torsion spring 13 ensures the stability of the engagement of the first lock buckle 11 and the second lock buckle 12 to a certain extent, and it is not easy to accidentally disengage by itself.

[0063] like Figure 5 As shown, in addition to the features of the above embodiments, the inner liner 2 is provided with a limit baffle 21 at the second lock buckle 12 , and when the second lock buckle 12 is buckled with the first lock buckle 11 , the second lock buckle 12 abuts against the limit baffle 21 .

[0064] Among them, the inner liner 2 is provided with a limit baffle 21 at the second lock buckle 12 for limiting the rotation angle of the second lock buckle 12. Specifically, when the second lock buckle 12 is engaged with the first lock buckle 11, the second lock buckle 12 abuts against the limit baffle 21. When the door body 3 is in an open state, and the second lock buckle 12 is reset to the position abutting against the limit baffle 21 under the action of the second torsion spring 13, it is prevented that the second lock buckle 12 rotates too much when resetting, resulting in the first lock buckle 11 on the door body 3 being unable to engage with the second lock buckle 12 on the inner liner 2 when the door body 3 is closed.

[0065] like Figure 1 and 4 As shown, in addition to the features of the above embodiments, the present embodiment further defines that: the door lock device also includes a micro switch 30, the micro switch 30 is arranged on the inner shell 2, a transition rocker 40 is arranged between the first lock buckle 11 and the micro switch 30, the transition rocker 40 is rotatably arranged on the inner shell 2, the contact of the micro switch 30 is arranged opposite to the transition rocker 40, when the door body 3 is in the first position, the first lock buckle 11 pushes the transition rocker 40 to rotate to squeeze the contact of the micro switch 30, and the micro switch 30 is used to detect the opening and closing state of the door body 3.

[0066] Among them, a micro switch 30 is arranged on the inner tank 2. When the door body 3 is in a closed state, the first lock buckle 11 and the contacts of the micro switch 30 are in a relatively set positional relationship. By setting a transitional pendulum 40 that can rotate on the inner tank 2 between the first lock buckle 11 and the micro switch 30, when the door body 3 gradually moves from the second position to the first position, the first lock buckle 11 pushes the transitional pendulum 40 to rotate, and then the transitional pendulum 40 presses the contacts of the micro switch 30, and then the micro switch 30 outputs a signal confirming that the door body 3 has completed the closing operation, so that the dishwasher can only carry out the cleaning task when it is confirmed that the door is closed, thereby improving the safety performance of the dishwasher.

[0067] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0068] The above embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
