The damping unit 40 in this embodiment further includes a spring 45, the spring 45 is sleeved outside the damping body 42, and two ends of the spring 45 are respectively connected to the connection end 44 and the damping body 42. When the oven door 400 is in the open state, the spring 45 is in the tensile state, and when the door latch 200 presses the buffer unit 40 through the connection unit 30 in the closing process of the oven door 400, the spring 45 is restored to the original state according to the elastic potential energy after the deformation of the spring 45, so that the force applied in the door closing process can be reduced, and the oven door 400 can be closed only by applying a small force to push the oven door 400. When the door 400 is in the closed state, the spring 45 is in a natural state or a compressed state.
As shown in fig. 11, when the door 400 is closed by the opening and closing door assembly 100 according to the present embodiment, the door 400 is pushed to move the latch 200 toward the opening and closing door assembly 100 and to insert the latch 200 into the mounting cavity. As shown in fig. 12, at this time, the latch 200 is just moved to a position where it is in contact with the first link 32 and the second link 33, neither the first link 32 nor the second link 33 is rotated, and the buffer unit 40 is not compressed. As shown in fig. 13, the latch 200 is pushed further, and the latch 200 presses the first link 32 and the second link 33, so that the first link 32 and the second link 33 start to rotate, and the first sliding column 321 slides in the arc segment 112. As shown in fig. 14, the latch 200 is pushed further, and the first link 32 and the second link 33 continue to rotate under the action of the latch 200 until the latch 200 is fully clasped, at which time the first sliding column 321 slides to the junction of the straight segment 111 and the arc segment 112. As shown in fig. 15, the latch 200 is pushed continuously, the slider 31 slides along the second chute 12 under the action of the latch 200, the first link 32 and the second link 33 slide along the straight section 111 of the first chute 11 under the action of the latch 200, and the spring 45 in the stretched state recovers its shape, thereby achieving the closing process of the oven door 200. In this process, the damping body 42 can play a one-way buffering role, so as to slow down the advancing speed of the latch 200, further reduce the impact force when the door 400 is closed, reduce or eliminate the impact noise generated when the door is closed, and improve the customer satisfaction.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention.
