[0002] With the development of society and the advancement of science and technology, people's requirements for life are getting higher and higher. More and more families have begun to use dishwashers to wash kitchen utensils, reducing people's housework burden. The working principle of a dishwasher is generally to fill water into the inner tank of the machine, heat it, add detergent, and then use a washing pump to pump water into the spray pipe for washing. After washing, the water is discharged through a drain pump. A dishwasher generally includes a body and a door panel. The body has a hollow washing cavity. An opening is opened on the front side of the body to open the washing cavity. The door panel is arranged on the front side of the body and is used to open or close the opening. When the door panel is closed, it is usually necessary to lock the door panel to the body with a door lock to ensure that the door panel will not open during the use of the dishwasher.

[0003] The Chinese patent with patent number 202211108310.6 (application publication number CN117731211A) discloses a door lock of a washing machine and a washing machine. The door lock includes a lock slot, a locking member, a pushing assembly, a trigger assembly and a driving assembly. The driving assembly is used to provide the locking member with a power to flip backwards so that the lock hook is lifted upwards when the lock hook of the locking member is out of the lock slot during the door opening process. The present invention is provided with a locking member that cooperates with the lock slot at the top of the door panel. In the closed door state, the lock hook of the locking member flips downwards to cooperate with the lock slot and engages. The pushing assembly always pushes the rear end of the locking member forward so that the lock hook is tightly hooked with the inner wall of the lock slot, so that the door panel always maintains a force to press against the washing machine body, thereby improving the sealing between the door panel and the body. When placing tableware in the bowl basket, the user needs to put down the tableware first and free up at least one hand to open the door panel, which brings certain inconvenience to the user.

[0031] In order to enable those skilled in the art to better understand the technical solution of the present disclosure, the present disclosure is described in detail, clearly and completely in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present disclosure and are not used to limit the present disclosure.

[0032] Those skilled in the art should understand that, in the disclosure of the present invention, the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be understood as limiting the present invention.

[0033] Please refer to Figure 1 , Figure 6 to Figure 8 As shown, a door panel mechanism for a dishwasher includes a rectangular inner door panel 2 and an outer door panel 1, wherein the inner door panel 2 is mounted on the inner side of the outer door panel 1, and the lower part of the outer door panel 1 is hinged to the inner tank of the dishwasher. Two knock sensing components 3 are arranged on the outer door panel 1, and a door lock component is arranged on the inner door panel 2. The door lock component and the knock sensing component 3 are respectively connected to the controller, and the knock sensing component 3 is used to sense the knocking of the outer door panel 1 and transmit the information to the controller, and the controller controls the door lock component to unlock. When the door lock component is locked, the outer door panel 1 is in a closed state, and the outer door panel 1 vibrates when the outer door panel 1 is knocked. The knock sensing component 3 senses the vibration and transmits the signal to the controller, and the controller controls the door lock component to unlock, and the outer door panel 1 opens. At this time, the user can place or take out tableware in the inner tank, and the user does not need to free up his hands to manually unlock it, which makes the door panel mechanism more intelligent and more convenient for users to use. It should be noted that for safety reasons, when the dishwasher is running, even if the outer door panel 1 is knocked, the outer door panel 1 of the dishwasher will not open. In the present disclosure, knocking on the outer door panel 1 will open the outer door panel 1, which is for the non-operating state of the dishwasher.

[0034] Furthermore, the knocking sensing component 3 includes a knocking panel 31 and a radar component. The radar component is arranged on the knocking panel 31, and the knocking panel 31 is installed on the outer door panel 1. When the user knocks, he / she should knock on the knocking panel 31, so that the knocking panel 31 can be obviously stressed, which is convenient for the sensing of the radar component. Specifically, the outer door panel 1 is provided with two mounting grooves, and the two mounting grooves are arranged along the width direction of the outer door panel 1, and the knocking sensing components 3 are respectively installed in the two mounting grooves. Preferably, at least one limiting column 32 is provided on the knocking panel 31, and the radar component is abutted against the limiting column 32. The limiting column 32 is arranged between the radar component and the knocking door panel, so that the radar component is tightly fitted with the knocking door panel through the limiting column 32, so that the radar component can sense more accurately.

[0035] Furthermore, the radar assembly includes a first radar 33a and a second radar 33b. The first radar 33a is used to sense the distance between a person and the outer door panel 1, and the second radar 33b is used to sense the force range of the door panel. The force range specifically refers to the area where the outer door panel 1 is subjected to force and the magnitude of the force. That is, the user needs to knock on the outer door panel 1 in a certain area (referring to the knocking panel 31) with a certain force so that the second radar 33b can sense the knocking. If the knocking is not done in the designated area or the knocking force is small, the force of the knocking panel 31 cannot be transmitted to the second radar 33b, and the second radar 33b cannot sense the force.

[0036] Specifically, the door lock assembly is electrically connected or signal-connected to the controller, and the radar assembly is electrically connected or signal-connected to the controller. When the force of knocking the outer door panel 1 is greater than or equal to aN, the radar assembly will sense the vibration caused by the knocking and transmit the signal to the controller. It should be noted that the value of a can be adjusted by the manufacturer. The smaller the value of a, the more sensitive the reaction. That is, if the value of a is small, the door panel mechanism can be unlocked by knocking the outer door panel 1 with very small force.

[0037] like Figure 2 to Figure 5 As shown, further, the door lock assembly includes a lock body assembly and a limit assembly, the lock body assembly includes a lock slot 4 and a lock tongue, when the door panel mechanism is in a locked state, the lock tongue is arranged in the lock slot 4, when the door panel mechanism is in an open state, the lock tongue is disengaged from the lock slot 4, the lock body assembly also includes a mounting seat 5, the lock slot 4 is arranged on the mounting seat 5, the limit assembly includes a limit rod 6, when the door panel mechanism is in a locked state, the limit rod 6 limits the mounting seat 5 to prevent the outer door panel 1 from being opened, the limit assembly has a simple and compact structure, effectively avoids pulling open the dishwasher during operation, makes the dishwasher safer, and improves the safety of the product and user experience. Specifically, the lock slot 4 is provided with an opening, preferably, the opening of the lock slot 4 is an arc-shaped opening, which is convenient for the lock tongue to enter and disengage, and the shape of the lock tongue is not specifically limited here.

[0038] Furthermore, the limit rod 6 is connected to a driving assembly 10, and the driving assembly 10 is used to drive the limit rod 6 to move the limit rod 6 to a position away from the mounting seat 5. The driving assembly 10 is electromagnetically driven or motor driven. The limit assembly is electrically connected to the controller; the lock body assembly is electrically connected to the controller.

[0039] The mounting seat 5 is connected with a first reset member 7, which is used to reset the outer door panel 1 when the outer door panel 1 is opened. The first reset member 7 is a spring. When the dishwasher door panel is opened to a certain extent, the first reset member 7 resets the door panel toward the inner tank of the dishwasher, so that the door panel is close to the inner tank of the dishwasher, which saves effort and makes it easier to close the door panel, thereby avoiding damage to the door panel and other components caused by huge vibration caused by closing the door panel vigorously.

[0040] Furthermore, the limiting rod 6 is connected to a second reset member 8, and the second reset member 8 is used to move the limiting rod 6 to the position of the mounting seat 5 to limit the mounting seat 5. The second reset member 8 is a spring. When the lock tongue and the lock groove 4 are matched and connected to lock the door panel, the limiting rod 6 moves toward the mounting seat 5 under the action of the second reset member 8 to limit the mounting seat 5.

[0041] Furthermore, a mounting shell 9 is provided on the inner door panel 2, a limiting assembly is at least partially provided in the mounting shell 9 and slides in the mounting shell 9, a driving assembly 10 is provided in the mounting shell 9, the mounting shell 9 is provided on the left or right side of the mounting seat 5, the limiting rod 6 is provided close to the mounting seat 5, and the driving assembly 10 is provided away from the mounting seat 5.
