Description

Technical Field

[0001] This utility model relates to the field of dishwashers, and in particular to a door lock structure and a dishwasher. Background Technology

[0002] Dishwashers, common kitchen appliances in modern homes, generate high-temperature, high-pressure water and steam during operation. To ensure the sealing and safety of the washing process and prevent children from accidentally opening the door out of curiosity, which could lead to burns, cuts, or leaks, most dishwashers on the market are equipped with child locks. However, current child locks often have overly complex locking mechanisms, taking up considerable internal space and directly affecting the size of the inner drum.

[0003] Therefore, it is necessary to make further improvements. Utility Model Content

[0004] The purpose of this invention is to overcome the above-mentioned problems. We provide a door lock structure and a dishwasher, which have a simple structure for child lock locking and high reliability.

[0005] To achieve the above objectives, this utility model provides a door lock structure, which includes a bottom shell, a bolt, and a locking mechanism. The bottom shell has an opening on one side, and a bolt track is provided inside the bottom shell corresponding to the opening. The bolt can enter the bolt track through the opening. A locking hole is provided on the bolt. The locking mechanism is located on one side of the bolt track. The locking mechanism includes a driver and a locking part. The driver can drive the locking part to connect with the locking hole. The connection between the locking part and the locking hole can prevent the bolt from exiting the bolt track.

[0006] In one or more embodiments, a signal triggering mechanism is provided inside the bottom shell, which sends a signal when the bolt enters the bolt channel.

[0007] In one or more embodiments, the signal triggering mechanism includes a micro switch and a rocker, the rocker being rotatably connected to the bottom shell, the first end of the rocker extending to the locking tongue, and the second end of the rocker remaining in the state of triggering the micro switch.

[0008] In one or more embodiments, a spring is provided inside the bottom shell, which applies a spring force to the rocker to ensure that the second end of the rocker triggers a micro switch.

[0009] In one or more embodiments, the driver is a telescopic motor, and the telescopic shaft of the telescopic motor is connected to a locking part.

[0010] In one or more embodiments, the bottom shell is provided with a slide rail for sliding connection of the locking part, the slide rail is provided with a slide groove for sliding connection of the locking part with the slide rail.

[0011] This utility model also provides a dishwasher, which includes a body and a door, and also includes the door lock structure described above. The bottom shell is fixed to the body, and the latch is fixed to the door.

[0012] Compared with the prior art, the advantages of this utility model are: by directly setting the locking mechanism on one side of the lock tongue, and using the driver to drive the locking part to cooperate with the locking hole on the lock tongue to achieve locking, the overall structure is compact and the number of parts is small, which effectively reduces the space occupied by the door lock inside the dishwasher and helps to increase the capacity of the dishwasher drum.

[0014] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0015] See appendix Figure 1-3 This application provides a door lock structure, including a base shell 1, a bolt 2, and a locking mechanism. An opening 3 is provided on one side of the base shell 1, and a bolt track 4 is provided inside the base shell 1 corresponding to the opening 3. The bolt 2 can enter the bolt track 4 through the opening 3. A locking hole 5 is provided on the bolt 2. The locking mechanism is located on one side of the bolt track 4 and includes a driver 6 and a locking part 7. The driver 6 can drive the locking part 7 to connect with the locking hole 5. The connection between the locking part 7 and the locking hole 5 prevents the bolt 2 from exiting the bolt track 4. By directly setting the locking mechanism on one side of the bolt track 4 and cooperating with the locking hole 5 on the bolt 2, locking and releasing of the bolt 2 are achieved. This solution reduces the number of parts and structural complexity, making the entire door lock structure very compact and space-saving, thus saving valuable internal space for appliances such as dishwashers and helping to increase the inner tank capacity.

[0016] The bottom shell 1 is equipped with a signal triggering mechanism. When the bolt 2 enters the bolt track 4, the signal triggering mechanism emits a signal. This mechanism can automatically emit a signal when the bolt 2 is fully inserted. This enables real-time detection and feedback of the door's status, providing crucial input information for the overall control system and enhancing the product's intelligence and security. The signal triggering mechanism includes a micro switch 8 and a rocker arm 9. The rocker arm 9 is rotatably connected to the bottom shell 1. The first end 91 of the rocker arm 9 extends to the latch 4, and the second end 92 of the rocker arm 9 remains in the state of triggering the micro switch 8. Utilizing the lever principle, the rocker arm 9 converts the linear motion of the latch 2 into the rotation of the rocker arm, thereby releasing the triggering of the micro switch. This mechanical triggering method has a rapid response, accurate action, long service life, and is easy to manufacture and maintain.

[0017] A spring 10 is provided inside the bottom shell 1. The spring 10 applies elastic force to the rocker 9 to ensure that the second end 92 of the rocker 9 triggers the micro switch 8. By adding the spring 10, a stable restoring force is provided for the rocker 9. This ensures that when the latch 2 is not inserted, the second end 92 of the rocker 9 can continuously and stably press on the micro switch 8, guaranteeing the determinism of the signal state and preventing false triggering or signal instability due to vibration or gravity, thereby further improving the reliability of signal detection.

[0018] The driver 6 is a telescopic motor, and the telescopic shaft of the telescopic motor is connected to the locking part 7. The telescopic motor can directly output linear motion, which is very suitable for driving the locking part 7 to insert and pull out the locking hole 5. This driving method has the advantages of precise control, fast response speed and simple structure.

[0019] The bottom shell is provided with a slide rail for sliding connection of the locking part 7. A slide rail 11 is provided on the slide rail, and the locking part 7 is provided with a groove that slides in connection with the slide rail 11. By setting the slide rail and the cooperation between the slide rail 11 and the groove, it is ensured that the locking part 7 can move smoothly and linearly along a predetermined path under the drive of the telescopic motor, preventing it from deviating, jamming or wearing during the movement, thereby ensuring that the locking part 7 and the locking hole 5 can be accurately connected.

[0020] See Figure 1 This application also provides a dishwasher, including a body 12 and a door 13. The dishwasher also includes the door lock structure described above. The bottom shell 1 is fixed to the body 12, and the latch 2 is fixed to the door 13.

[0021] The above description is only a preferred embodiment of the present utility model. The protection scope of the present utility model is not limited to the above embodiments. Any equivalent modifications or changes made by those skilled in the art based on the content disclosed in the present utility model should be included in the protection scope recorded in the claims.
