[0030] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0031] Reference below Figures 1-6 A door locking device 100 according to an embodiment of the first aspect of the present invention is described.

[0032] like Figures 1-6 As shown, the door lock device 100 according to the embodiment of the first aspect of the present invention is used for a dishwasher. The dishwasher includes: a dishwasher body and a door body. The door lock device 100 is suitable for being connected between the dishwasher body and the door body. The door lock device 100 includes: a lock body 10, a lock rod 20 and a lock buckle 30.

[0033] The locking bar 20 moves in a first direction (eg Figure 1 The lock body 10 is movably provided with a lock rod 20 and a first locking portion 21; the lock catch 30 is provided with a second locking portion 31, one of the first locking portion 21 and the second locking portion 31 is formed as a locking block 311 and the other is formed with a locking groove 210, the opening of the locking groove 210 faces one side of the first direction, and the locking block 311 is movable along the second direction (for example Figure 1 The locking rod 20 and the locking buckle 30 are provided with a limiting structure 32, and the limiting structure 32 is configured to limit the locking block 311 from disengaging from the locking slot 210 along the second direction.

[0034] It should be noted that, in a specific example, Figure 1As shown, the first direction is the front-to-back direction, and the second direction is the up-down direction, with the second direction intersecting the first direction. Specifically, the dishwasher is provided with a drive motor, and the lock body 10 is provided with a transmission mechanism. Furthermore, a rack is formed at the rear end of the lock rod 20. One end of the transmission mechanism is in driving connection with the motor shaft of the drive motor, and the other end of the transmission mechanism is in driving connection with the rack.

[0035] It should be noted that a transmission connection refers to the connection of two or more components through some assembly method to achieve force or power transmission. A transmission connection effectively transfers force or power from one component to another, enabling the entire system to function properly. The two components of a transmission connection can be connected directly or indirectly, as long as the force transmission is achieved.

[0036] When the drive motor is working, the drive motor can drive the rack to move forward or backward through the transmission mechanism, thereby moving the lock rod 20 forward or backward. Figure 1 As shown, the movement distance of the lock rod 20 is greater than or equal to 90 mm and less than or equal to 100 mm, thereby allowing the dishwasher door to open a gap of appropriate size, thereby effectively discharging moisture, reducing mold and odor, and accelerating the drying process of dishes. For example, the movement distance of the lock rod 20 can be 90 mm, 92 mm, 94 mm, 96 mm, 98 mm, and 100 mm.

[0037] For example, a locking groove 210 is formed in the first locking portion 21, and a locking block 311 is formed in the second locking portion 31; for another example, a locking block 311 is formed in the first locking portion 21, and a locking groove 210 is formed in the second locking portion 31. Figure 1 As shown, the first locking portion 21 is located at the left end of the locking rod 20, a locking groove 210 is formed in the first locking portion 21, and a locking block 311 is formed in the second locking portion 31. Furthermore, the locking groove 210 passes through the first locking portion 21 in the up and down directions, and an opening is formed at the front end of the locking groove 210, and the opening passes through the first locking portion 21 in the front and back directions.

[0038] For example, the locking rod 20 may be provided with a limiting structure 32; for another example, the locking buckle 30 may be provided with a limiting structure 32; for another example, both the locking rod 20 and the locking buckle 30 may be provided with a limiting structure 32. In a specific example, Figure 1 As shown, a limiting structure 32 is provided on the lock buckle 30, and the limiting structure 32 can limit the movement of the locking block 311 relative to the locking slot 210 in the vertical direction, thereby effectively preventing the locking block 311 from being separated from the locking slot 210 in the vertical direction.

[0039] In this embodiment, when the dishwasher senses that the washing program is over, the dishwasher can control the door body to open automatically, that is, the dishwasher can control the door body to rotate and open so that a gap is formed between the door body and the dishwasher body. In the process of the door body being gradually opened, the locking block 311 of the second locking part 31 and the locking groove 210 formed by the first locking part 21 will produce relative sliding in the up and down directions. Through the limiting structure 32, the locking block 311 of the second locking part 31 and the locking groove 210 formed by the first locking part 21 can be effectively prevented from sliding relative to each other in the up and down directions, thereby effectively preventing the locking block 311 from disengaging from the locking groove 210 in the up and down directions during the door body opening process.

[0040] After the dishwasher door automatically opens, it can expel moisture, reduce mold and odor, and accelerate the drying process of the dishes. Afterwards, the dishwasher can control the door to automatically close, that is, the dishwasher can control the door to rotate so that the door is ultimately closed. As the door gradually closes, the limiting structure 32 can also effectively prevent the lock block 311 from disengaging from the lock slot 210 in the vertical direction. Thus, the door lock device 100 of the present application can effectively prevent the lock block 311 from disengaging from the lock slot 210 in the second direction during the door opening and closing process, thereby effectively ensuring the reliability of the dishwasher's automatic door opening and closing function.

[0041] According to the door lock device 100 of an embodiment of the present invention, a lock body 10, a lock rod 20 and a lock buckle 30 are provided in the door lock device 100, the lock rod 20 is movably provided on the lock body 10 along a first direction, the lock rod 20 is provided with a first locking portion 21, and the lock buckle 30 is provided with a second locking portion 31, one of the first locking portion 21 and the second locking portion 31 is formed as a lock block 311 and the other is formed with a lock groove 210, the opening of the lock groove 210 is facing one side of the first direction, the lock block 311 is movably engaged in the lock groove 210 along the second direction, and the second direction intersects with the first direction, wherein at least one of the lock rod 20 and the lock buckle 30 is provided with a limiting structure 32, which is configured to limit the lock block 311 from disengaging from the lock groove 210 along the second direction, which can effectively prevent the lock block 311 from disengaging from the lock groove 210 along the second direction during the door body opening and closing process, thereby effectively improving the reliability of the door lock device 100, and then effectively improving the user experience.

[0042] In one embodiment of the present invention, Figures 1-6 As shown, the limiting structure 32 is provided on the lock buckle 30 and includes a first limiting rib 321. The first limiting rib 321 is located on the side of the lock slot 210 away from the fixed end 34 of the lock buckle 30 in the second direction, and is suitable for abutting against at least one side edge of the lock slot 210 in the third direction to limit the locking block 311 from detaching from the lock slot 210. The third direction intersects with both the second direction and the first direction.

[0043] It should be noted that, in a specific example, Figure 1 As shown, the third direction is the left-right direction, and the third direction intersects both the second direction and the first direction. In a specific example, as Figure 1 and Figure 2 As shown, the fixed end 34 of the lock buckle 30 is arranged on the lower side of the lock buckle 30, the first limiting rib 321 is located on the upper side of the lock slot 210, and the first limiting rib 321 abuts against the first locking parts 21 on the left and right sides of the lock slot 210 in the upper and lower directions, thereby effectively preventing the lock block 311 from detaching from the lock slot 210 during the opening and closing process of the dishwasher door.

[0044] In this embodiment, a limiting structure 32 is provided on the lock buckle 30, and a first limiting rib 321 is provided in the limiting structure 32. The first limiting rib 321 is located on the side of the lock slot 210 that is away from the fixed end 34 of the lock buckle 30 in the second direction, and is suitable for abutting against at least one side edge of the lock slot 210 in the third direction to limit the lock block 311 from disengaging from the lock slot 210. The third direction intersects with both the second direction and the first direction, and can effectively limit the first locking portion 21 from moving relative to the lock block 311 in the second direction toward the side of the fixed end 34 away from the lock buckle 30, thereby effectively realizing the limiting effect of the limiting structure 32. In addition, the first limiting rib 321 has a simple structure, is easy to produce and manufacture, and can effectively reduce costs.

[0045] In one embodiment of the present invention, Figures 1-6 As shown, the first direction is the front-to-back direction of the dishwasher, the second direction is the up-down direction of the dishwasher, and the third direction is the left-to-right direction of the dishwasher.

[0046] In a specific example, a dishwasher body includes a washing chamber, the front of which is open to form an opening. A dishwasher door is provided at the front of the dishwasher body for opening and closing the opening. The lower end of the door is rotatably connected to the dishwasher body, a lock catch 30 is provided at the upper portion of the door, and a lock body 10 is provided at the upper portion of the dishwasher body.

[0047] Furthermore, for example Figure 1 As shown, the lock rod 20 extends forward and backward, and a rack is formed at the rear end of the lock rod 20, which is in driving connection with the transmission mechanism of the lock body 10. A lock slot 210 is formed at the front end of the lock rod 20, extending vertically through the lock rod 20. The opening of the lock slot 210 is arranged forward. The lower end of the lock catch 30 is a fixed end 34 and is fixed to the door body. The upper end of the lock catch 30 is formed into a lock block 311. A first limiting rib 321 is connected to the lock block 311 and is arranged on the upper side of the lock block 311. When the lock block 311 is engaged in the lock slot 210, the first limiting rib 321 is located on the upper side of the lock rod 20.

[0048] In one embodiment of the present invention, Figures 1-6As shown, the first limiting rib 321 extends along the third direction, and the first limiting rib 321 is one or a plurality of first limiting ribs 321 arranged at intervals along the third direction. Figures 1-6 As shown, the first limiting rib 321 is extended in the left-right direction, thereby effectively increasing the contact area between the first limiting rib 321 and the first locking portion 21 .

[0049] For example, the number of the first limiting rib 321 may be one; for another example, the number of the first limiting rib 321 may be multiple and spaced apart along the left-right direction. For example, the number of the first limiting rib 321 may be two, three, four, five, six or more spaced apart along the left-right direction. Figure 3-Figure 5 As shown, the number of the first limiting rib 321 is one. Setting the number of the first limiting rib 321 to one can effectively simplify the structure of the limiting structure 32. In a specific example, as shown in FIG. Figure 6 As shown, the number of the first limiting ribs 321 is two arranged at intervals along the left and right directions. Setting the number of the first limiting ribs 321 to two arranged at intervals along the left and right directions can ensure that the first limiting ribs 321 are subjected to uniform and reliable force when abutting against the first locking portion 21.

[0050] In this embodiment, by setting the first limiting rib 321 to extend along the third direction, the contact area of ​​the first limiting rib 321 when abutting against the first locking portion 21 can be effectively increased, thereby effectively avoiding the phenomenon of stress concentration, and further effectively protecting the first limiting rib 321 and the first locking portion 21; by setting the number of the first limiting rib 321 to one, the structure of the limiting structure 32 can be effectively simplified and the cost can be reduced; by setting the number of the first limiting rib 321 to multiple, the uniformity of the force applied to the first limiting rib 321 when abutting against the first locking portion 21 can be effectively improved, thereby effectively improving the stability of the force applied to the first limiting rib 321.

[0051] In one embodiment of the present invention, Figure 3-Figure 6 As shown, the limiting structure 32 also includes: a second limiting rib 322, the second limiting rib 322 and the first limiting rib 321 are respectively located on both sides of the lock slot 210 in the second direction, and in the second direction, the first locking portion 21 is located between the first limiting rib 321 and the second limiting rib 322.

[0052] For example, the first limiting rib 321 is located on the upper side of the locking slot 210, and the second limiting rib 322 is located on the lower side of the locking slot 210. That is, in the up and down directions, the first locking portion 21 is located between the first limiting rib 321 and the second limiting rib 322. In some specific examples, such as Figure 3-Figure 6As shown, the first limiting rib 321 is located on the upper side of the lock slot 210, and the second limiting rib 322 is located on the lower side of the lock slot 210. Furthermore, the second limiting rib 322 is extended along the left and right directions, and the second limiting rib 322 is one or multiple ones arranged at intervals along the left and right directions.

[0053] In this embodiment, a second limiting rib 322 is provided in the limiting structure 32. The second limiting rib 322 and the first limiting rib 321 are respectively located on both sides of the lock slot 210 in the second direction. In the second direction, the first locking portion 21 is located between the first limiting rib 321 and the second limiting rib 322, which can effectively limit the movement of the first locking portion 21 relative to the locking block 311 in the second direction, thereby further improving the reliability of the limiting structure 32. In addition, the second limiting rib 322 can effectively improve the strength and rigidity of the limiting structure 32, thereby effectively improving the service life of the limiting structure 32.

[0054] In one embodiment of the present invention, Figure 3-Figure 6 As shown, the limiting structure 32 also includes: a limiting plate 323, which is connected to the locking block 311, and the limiting plate 323 is located on the side of the lock slot 210 away from the lock body 10 in the first direction, and is opposite to the opening of the lock slot 210. In the third direction, the width of the limiting plate 323 is greater than the width of the opening of the lock slot 210, and the first limiting rib 321 is formed on one side edge of the limiting plate 323 in the second direction.

[0055] For example Figure 3-Figure 6 As shown, the limiting plate 323 can be a rectangular plate extending in the up-down direction. The limiting plate 323 is located in front of the locking block 311. The rear side of the limiting plate 323 is fixedly connected to the front end of the locking block 311, and the limiting plate 323 is directly opposite to the opening of the locking slot 210 in the front-to-back direction. Furthermore, the limiting plate 323 and the locking block 311 can be made by an integrated molding process. For example, the first limiting rib 321 is formed on the upper edge of the limiting plate 323. In some specific examples, for example Figure 3-Figure 6 As shown, the first limiting rib 321 is formed on the upper edge of the limiting plate 323 .

[0056] In this embodiment, a limiting plate 323 is provided in the limiting structure 32, and the limiting plate 323 is connected to the lock block 311. The limiting plate 323 is located on the side of the lock slot 210 that is away from the lock body 10 in the first direction and is opposite to the opening of the lock slot 210. In the third direction, the width of the limiting plate 323 is greater than the width of the opening of the lock slot 210. The first limiting rib 321 is formed on one side edge of the limiting plate 323 in the second direction, which can effectively limit the movement distance of the first locking portion 21 relative to the lock block 311 in the first direction, thereby preventing the first locking portion 21 from moving too far relative to the lock block 311 in the first direction, thereby effectively ensuring the reliability of the automatic opening and closing function of the dishwasher door.

[0057] In one embodiment of the present invention, Figure 3 As shown, one side edge of the limiting plate 323 in the second direction is bent along the first direction toward the locking block 311 to form a first limiting rib 321. In a specific example, as shown in FIG. Figure 3 As shown, the upper edge of the limiting plate 323 is bent along the front-to-back direction toward the locking block 311 to form a first limiting rib 321 .

[0058] This embodiment forms a first limiting rib 321 by bending one side edge of the limiting plate 323 in the second direction along the first direction toward the locking block 311, which can effectively simplify the structural construction of the limiting structure 32 and avoid setting the first limiting rib 321 separately, thereby effectively reducing the number of components in the limiting structure 32. In addition, it can also effectively simplify the manufacturing process of the first limiting rib 321, thereby effectively reducing the difficulty of manufacturing the first limiting rib 321.

[0059] In one embodiment of the present invention, Figure 3-Figure 6 As shown, the limiting plate 323 is connected to the locking block 311 through a first limiting rib 321, and / or the limiting structure 32 also includes a connecting rib 324. In a first direction, one end of the connecting rib 324 is connected to the locking block 311 and the other end passes through the opening of the lock slot 210 and is connected to the limiting plate 323. In a second direction, the connecting rib 324 extends from one end of the limiting plate 323 to the other end.

[0060] In a specific example, Figure 4 As shown, the limiting plate 323 is connected to the locking block 311 through the first limiting rib 321. The first limiting rib 321 is arranged on the upper side of the locking block 311 and the first limiting rib 321 is fixedly connected to the locking block 311. The front end of the first limiting rib 321 is fixedly connected to the upper end of the limiting plate 323. Thus, the limiting plate 323 can be connected to the locking block 311 through the first limiting rib 321.

[0061] In some specific examples, such as Figure 3 、 Figure 5 and Figure 6 As shown, a connecting rib 324 is provided in the limiting structure 32, and the connecting rib 324 extends in the front-to-back direction. The rear end of the connecting rib 324 is fixedly connected to the locking block 311, and the front end of the connecting rib 324 passes through the opening of the locking groove 210 and is fixedly connected to the rear side surface of the limiting plate 323. Furthermore, the connecting rib 324, the limiting plate 323 and the locking block 311 can be made by an integrated molding process.

[0062] In this embodiment, the limit plate 323 is connected to the locking block 311 through the first limit rib 321, and / or the limit structure 32 also includes a connecting rib 324. In the first direction, one end of the connecting rib 324 is connected to the locking block 311 and the other end passes through the opening of the locking groove 210 and is connected to the limit plate 323. In the second direction, the connecting rib 324 extends from one end of the limit plate 323 to the other end, which can effectively improve the structural strength of the connection between the first limit rib 321 or the limit plate 323 and the locking block 311, so that the first limit rib 321 or the limit plate 323 can be firmly fixed on the locking block 311, thereby ensuring the stability of the locking block 311 in the locking groove 210, thereby effectively ensuring the stability of the limit structure 32.

[0063] In one embodiment of the present invention, Figure 1 and Figure 2 As shown, the end of the lock rod 20 facing away from the lock body 10 is provided with two claws 211, and the two claws 211 are arranged in a third direction to cooperate to define a lock slot 210. The third direction intersects with both the second direction and the first direction. In a specific example, as shown in FIG. Figure 1 and Figure 2 As shown, two claws 211 are provided at the front end of the first locking portion 21 of the locking rod 20 . The two claws 211 are spaced apart in the left-right direction, and a locking groove 210 is formed between the two claws 211 .

[0064] In this embodiment, two claws 211 are provided at the end of the lock rod 20 facing away from the lock body 10. The two claws 211 are arranged at intervals in the third direction to cooperate in defining a lock slot 210. The third direction intersects with both the second direction and the first direction. This not only effectively prevents the lock block 311 from escaping from the lock slot 210 along the third direction, but also effectively simplifies the structural structure of the lock rod 20, thereby avoiding the provision of additional components and effectively reducing costs.

[0065] In one embodiment of the present invention, Figure 1 and Figure 2 As shown, the ends of the two claws 211 facing away from the lock body 10 extend toward each other and cooperate to define the opening of the lock slot 210. In a specific example, as shown in FIG. Figure 2 As shown, the front end of the left clamping claw 211 extends rightward, and the front end of the right clamping claw 211 extends leftward. The opening of the locking slot 210 is located between the front ends of the left clamping claw 211 and the right clamping claw 211.

[0066] In this embodiment, the ends of the two claws 211 facing away from the lock body 10 are arranged to extend toward each other, and the opening of the lock slot 210 is defined in cooperation with each other. This allows the claws 211 to better clamp the lock block 311, thereby preventing the lock block 311 from accidentally falling off from the lock slot 210 due to vibration generated during the opening and closing process of the dishwasher door, thereby effectively strengthening the locking effect of the claws 211 on the lock block 311.

[0067] In one embodiment of the present invention, Figure 1 and Figure 2 As shown, along the first direction, the width of the locking block 311 in the third direction first gradually increases and then gradually decreases, and the third direction intersects with both the second direction and the first direction.

[0068] In a specific example, Figure 2 As shown, the locking block 311 includes a first portion 3111 and a second portion 3112. The first portion 3111 is disposed in front of the second portion 3112. Along the front-to-back direction, the width of the first portion 3111 gradually increases in the left-to-right direction. Along the front-to-back direction, the width of the second portion 3112 gradually decreases in the left-to-right direction.

[0069] Furthermore, the two claws 211 can drive the lock catch 30 to move by abutting against the first portion 3111. Furthermore, the two claws 211 can move relative to each other in the left-right direction. In other words, the two claws 211 can deform in the left-right direction, thereby causing the locking block 311 to be located within or disengaged from the locking slot 210. When the locking block 311 is located within the locking slot 210, the dishwasher door can be automatically opened or closed. When the locking block 311 is disengaged from the locking slot 210, the dishwasher door can be fully opened to load or unload dishes.

[0070] In this embodiment, the width dimension of the locking block 311 in the third direction is set to gradually increase and then gradually decrease along the first direction. The third direction intersects with the second direction and the first direction. This not only increases the contact area between the claw 211 and the locking block 311, thereby effectively increasing the friction between the claw 211 and the locking block 311, but also enables the locking block 311 to play a guiding role, thereby facilitating the locking block 311 to move into or out of the locking slot 210, thereby effectively improving the convenience of operation.

[0071] A dishwasher according to an embodiment of the second aspect of the present invention includes: a dishwasher body, a door body, and the door locking device 100 according to the embodiment of the first aspect of the present invention.

[0072] The dishwasher body defines a washing chamber, one side of which is open, and the door body is connected to the dishwasher body for opening and closing the opening of the washing chamber; one of the lock body 10 and the lock buckle 30 is fixed to the dishwasher body and the other is fixed to the door body, and the door lock device 100 has an unlocked state and a locked state. In the locked state, the lock block 311 is engaged in the lock groove 210, and in the unlocked state, the lock block 311 is separated from the lock groove 210 from the opening of the lock groove 210 along a first direction.

[0073] For example, the lock body 10 is fixed to the dishwasher body and the lock catch 30 is fixed to the door body; for another example, the lock body 10 is fixed to the door body and the lock catch 30 is fixed to the dishwasher body. In a specific example, the lock body 10 is fixed to the dishwasher body and the lock catch 30 is fixed to the door body. Figure 3-Figure 6 As shown, the lock catch 30 is also provided with a connecting plate 33 and a fixed end 34. The connecting plate 33 is fixedly connected to the lower side of the lock block 311, and the fixed end 34 is fixedly connected to the lower side of the connecting plate 33. A mounting groove is provided on the door body, and the fixed end 34 can be installed in the mounting groove. A screw hole 340 is provided on the fixed end 34, and the lock catch 30 can be fixed to the door body through the screw hole 340.

[0074] When the door lock device 100 is locked, the lock body 10 drives the lock rod 20 to move, which in turn drives the door body to rotate via the lock catch 30, thereby automatically opening or closing the door body. In one specific example, the door body rotates at an angle of greater than or equal to 6° and less than or equal to 8°. For example, the door body can rotate at angles of 6°, 6.5°, 7°, 7.5°, and 8°. When the door lock device 100 is unlocked, the lock block 311 disengages from the opening of the lock slot 210 in the front-to-back direction, thereby fully opening the door body to insert or remove tableware.

[0075] According to the dishwasher of the embodiment of the present invention, by providing the door lock device 100 of the first embodiment described above, it is possible to effectively prevent the lock block 311 from disengaging from the lock slot 210 along the second direction during the door opening and closing process, thereby effectively improving the reliability of the door lock device 100 and further effectively improving the user experience.
