The above-described driving mechanism is a push rod motor 6 located behind the case 1, and is vertically arranged (i.e., arranged along the arrangement direction of the case and the door). The push rod motor 6 has a push rod 61 extending in the up-down direction, and the push rod motor in this embodiment adopts the structure and the working principle in the prior art, and will not be described in detail in this embodiment. The lower end of the push rod motor 6 is hinged on the rear wall surface of the box body 1, and the free end (upper end) of the push rod 61 of the push rod motor 6 is connected with the position adjacent to the middle of the rotating shaft 5 through a bracket, so that when the push rod 61 of the push rod motor 6 moves downwards, the lower end of the fourth connecting rod 33 is driven to rotate towards the convex part 21 (i.e. forwards), at the moment, the first connecting rod 31 moves upwards, and then the extension 321 of the second connecting rod 32 is in a first state with the function of rotating (rotating upwards) towards the direction far away from the box body 1 until the convex part 21 can be separated from the groove 311; thus, the front side of the door body 2 can be rotated upward with respect to the first link 31 to open the opening 101, or rotated downward to close the opening 101. Alternatively, when the push rod 61 of the push rod motor 6 moves upward, the second end (i.e., the lower end) of the fourth link 33 is driven to rotate in a direction away from the protruding portion 21 (i.e., backward), at this time, the first link 31 moves downward, and then the extension 321 of the second link 32 is brought into a second state of rotating in a direction toward the case 1 (i.e., rotating downward) to restrict the protruding portion 21 from coming out of the recess 311.

The rear side of the upper surface of the extension wall 102 is provided with a water guide plate 7 for sweeping water into the cavity 10, the water guide plate 7 extends in the left-right direction, the water guide plate 7 is rotatably disposed on the extension wall 102 adjacent to the first side (front side) of the protrusion 21, and the rotation axis of the water guide plate 7 extends in the left-right direction, in this embodiment, the top surface of the water guide plate 7 has an inclined surface 70 inclined gradually downward from rear to front, and the inclined surface 70 is located in front of the top surface of the water guide plate 7. The second side (i.e., the rear side) of the water guide plate 7 opposite to the first side is turned over along the movement direction of the first link 31, and the movement directions of the two are identical. In order to realize the rotation of the rear side of the water guide plate 7, the left and right sides of the water guide plate 7 are provided with connecting pieces 8, the two connecting pieces 8 are arranged at intervals along the left and right direction of the length direction of the water guide plate 7, and the two connecting pieces 8 have the same structural form, and one of the connecting pieces 8 is taken as an example for illustration. The upper part of the connecting piece is provided with a movable rod 81 for driving the rear side of the water guide plate 7 to turn over, the movable rod 81 extends along the vertical direction, the extending wall 102 is provided with a through hole for the upper end of the movable rod 81 to pass out, the upper end of the movable rod 81 is connected with the rear side of the water guide plate 7, and the connecting piece 8 is provided with an arc hole 82 gradually bending downwards along the front-rear direction (namely, the arc hole 82 gradually bending along the arrangement direction of the third connecting rod 34 and the second connecting rod 32 towards the direction far away from the door body 2). When the push rod 61 of the push rod motor 6 moves up and down, it moves back and forth along the length direction of the arc hole 82, so that the movable rod 81 slides up and down, and then the rear side of the water guide plate 7 rotates up and down, and then the water guide plate 7 is in an inclined state or a horizontal state. When the first link 31 moves upward, the rear side of the water guide plate 7 rotates upward, and when the first link 31 moves downward, the rear side of the water guide plate 7 rotates downward, i.e., the movement directions of the rear sides of the first link 31 and the water guide plate 7 coincide. In the closed state, the water guide plate 7 is hidden in the gap between the door body and the box body, and the appearance is not affected.

The working process of the cleaning machine is as follows:

as shown in fig. 7 and 8, when drying, the push rod 61 of the push rod motor 6 moves downward, the fourth link 33 rotates counterclockwise, the third link 34 rotates counterclockwise synchronously, and the first link 31 is pushed upward to move the first link 31 upward, at this time, the door 2 moves upward along with the first link 31 until stopping after reaching a certain height due to the fact that the door 2 is connected with the first link 31 through the cooperation of the protrusion 21, the groove 311 and the extension 321, at this time, the second link 32 rotates counterclockwise around the first shaft 322 to a state that the extension 321 is located at the rear side of the top opening of the groove 311, at this time, the protrusion 21 can move upward from the groove 311, and a gap is left between the door 2 and the extension wall 101 of the box 1, so that water vapor can be discharged from the chamber 10 rapidly, and drying effect in the chamber 10 is improved.

When the door needs to be opened, the user can pull the front side of the door body 2 to move upwards, at this time, the convex part 21 can be separated from the concave groove 311, and the door can be rotated upwards relative to the first connecting rod 31 to be in an opened state, and at this time, the user can take tableware from the container 10. Because the whole door body floats upwards, if the door body 2 is covered by all glass, when the normal door body does not float upwards, the rear glass of the door body 2 can touch the accommodating cavity 10, and the glass has the risk of damage. When the door body 2 floats upwards, the door body 2 is in a suspension state, the glass can not contact any object after the door body is opened, and the glass can not be damaged. Meanwhile, as the door body 2 floats upwards, no dead space is left between the rear side of the door body 2 and the containing cavity 10, and cleaning is convenient. As shown in fig. 4 to 6, when the door is opened, water on the door body flows onto the water guide plate 7, and the rear side of the water guide plate 7 is rotated upward, so that the water guide plate 7 is inclined gradually downward from the rear to the front, and at this time, water flowing down through the inner surface of the door body 2 falls onto the water guide plate 7 and flows into the cavity 10 under the guiding action of the water guide plate 7, thereby preventing water accumulation on the rear side of the extension wall. According to the requirements of tableware storage, the door body 2 can be moved upwards (in a drying state) periodically to ensure the drying of the accommodating cavity 10 and the tableware storage effect.

If the user wants to store the tableware in the cavity 10, in order to prevent dust and other things from entering the cavity 10 and polluting the tableware, after drying, the push rod 61 of the push rod motor 6 moves upwards to drive the fourth connecting rod and the third connecting rod to move clockwise, the first connecting rod and the door body 2 move downwards until returning to the door-closing state, during the process, the second connecting rod 32 moves clockwise, at this time, the extension 321 is located above the top opening of the groove 311, and the extension 321 blocks the protrusion 21 from moving upwards out of the top opening of the groove 311, so that the door body 2 is prevented from moving upwards relative to the box body 1, i.e. the door body 2 is in a locked state and cannot be opened. As shown in fig. 1 to 3, in the door-closed state, the rear side of the water guide plate 7 is rotated downward until the bottom surface of the water guide plate 7 changes from the inclined state to the horizontal state upon closing the door.

The cleaning machine can effectively improve the drying effect, does not need to be provided with a top door motor and a door lock, can save more space for the containing cavity 10, and increases the capacity of the containing cavity 10.
