In this embodiment, the two sliding blocks 223 located on the same side are fixed on the same sliding seat 224. A back guard bar 25 is provided above the tableware placement position. In the figure, the two ends of the back guard bar 25 are installed on the sliding block 223 of the upper guide rail 222. If the height of the tableware is shorter, the user can remove the back guard bar 25 from the sliding block 223 of the upper guide rail 222, and then install it on the sliding block 223 of the lower guide rail 222. Similarly, the user can remove the back rail 25 from the sliding block 223 of the lower rail 222 and then install it on the sliding block 223 of the upper rail 222. Figure 5As shown, the rotating blade 21 is provided with a moving rod 26 (i.e., a moving part), a motor 291, and a screw rod 292 connected to the output shaft of the motor 291. The moving rod 26 is sleeved on the screw rod 292 through a threaded hole. Two connecting rod transmission groups are provided between the rotating blade 21 and the bearing seat 22. The connecting rod transmission group includes a first connecting rod 27 and a second connecting rod 28. Figure 5 The end closer to the reader is the front, and the left side in the figure is the left side. The front and rear ends of the moving rod 26 are respectively hinged to the left ends of the two first connecting rods 27. The right end of the first connecting rod 27 in the front is hinged to the middle of the front side of the bearing seat 22, and the right end of the first connecting rod 27 in the rear is hinged to the middle of the rear side of the bearing seat 22. The proximal ends of the two second connecting rods 28 are respectively hinged to the middle of the two first connecting rods 27, and the distal ends of the two second connecting rods 28 are respectively fixedly connected to the sliding seats 224 on both sides.

[0025] The cabinet surface of the smart cabinet is provided with a touch panel electrically connected to the main control unit. The drum dishwasher 100 includes a controller electrically connected to the main control unit. If the user needs to wash the dishes, he clicks the dishware placement button on the touch panel to trigger the dishware placement instruction, and the main control unit sends a dishware placement instruction to the controller of the drum dishwasher 100. The drum dishwasher 100 has a dishware access window 110 on the top, and is provided with an electric cover (not shown in the figure) for closing the dishware access window 110. A camera is provided on the cavity wall at the top of the cleaning cavity. After receiving the dishware placement instruction, the controller of the drum dishwasher 100 identifies the dishware fixing mechanism 20 with an empty dishware placement position through the camera, and causes the electric cover to open the dishware access window 110, and then causes the rotary motor to drive the central shaft 10 to rotate, so that the dishware fixing mechanism 20 with an empty dishware placement position rotates to the bottom of the dishware access window 110. At this time, the dishware fixing mechanism 20 is in a state as shown in FIG. Figure 6 In the retracted state shown, the end of the rotating blade 21 is facing upwards, and no tableware is placed on the tableware placement position. Figure 6 The tableware 24 shown in FIG. Figure 7 As shown, the controller controls the motor 291 to drive the screw rod 292 to rotate, thereby driving the moving rod 26 from the starting end of the rotating blade 21 (that is, the moving rod 26 is at the Figure 7 The first connecting rod 27 moves radially to the end of the rotating blade 21. During this process, the first connecting rod 27 moves radially with the moving rod 26, thereby pushing the bearing seat 22 to rotate upward around the hinge between the bearing seat 22 and the rotating blade 21 until it is perpendicular to the rotating blade 21. At the same time, the first connecting rod 27 also drives the second connecting rod 28 to move upward, so that the second connecting rod 28 drives the sliding seat 224 to move, so that the sliding block 223 drives the back bar 25 to slide along the guide rail 222 to the rightmost end. At this time, the tableware fixing mechanism 20 is converted into Figure 4 In the open state shown in FIG. 1 , the support seat 22 is placed flat in the tableware placement window 110. Figure 1 or Figure 2As the back rail 25 is located at the rightmost end, the tableware placement position is not blocked, and the user can put the dirty tableware 24 upside down on the protrusion 23 to cover the protrusion 23, as shown in FIG. Figure 1 shown.

[0026] After placing the dirty dishes 24, the user can click the retract button on the touch panel to trigger the retract command. The master control unit sends the retract command to the controller of the drum dishwasher 100. After receiving the retract command, the controller controls the motor 291 to drive the screw rod 292 to reverse, thereby driving the moving rod 26 from the end of the rotating blade 21 (i.e., the moving rod 26 is at the bottom of the rotating blade 21). Figure 4 The first connecting rod 27 pulls the supporting seat 22 to rotate downward around the hinge between the supporting seat 22 and the rotating blade 21, and moves toward the starting end of the rotating blade 21. During this process, the first connecting rod 27 pulls the supporting seat 22 to rotate downward around the hinge between the supporting seat 22 and the rotating blade 21, and moves toward the rotating blade 21 until it moves into the cleaning chamber and overlaps with the rotating blade 21. At the same time, the first connecting rod 27 also pulls the second connecting rod 28 to move downward, so that the second connecting rod 28 drives the sliding seat 224 to move, so that the sliding block 223 drives the back bar 25 to slide in the opposite direction along the guide rail 222 to the other end. Figure 6 As shown, at this time, the back stopper 25 stops at the back of the tableware 24, thereby fixing the tableware 24 at the tableware placement position, and then the electric cover is controlled to close the tableware placement window 110.

[0027] like Figure 2 As shown, in this embodiment, the central shaft 10 is hollow and also serves as a main water supply line. A water pump (not shown in the figure) connected to the central shaft 10 is provided at the bottom of the dishwasher. A nozzle (not shown in the figure) connected to the water pump is provided on the inner side of the wall of the cleaning chamber. Figure 5 As shown, a radial water supply branch pipe 41 is provided in the middle of the rotating blade 21 in the radial direction, and an axial water supply branch pipe 42 is provided in the axial direction at the end of the rotating blade 21. The proximal end of the radial water supply branch pipe 41 is connected to the central rotating shaft 10, and the distal end is connected to the axial water supply branch pipe 42. The axial water supply branch pipe 42 extends a rotating water outlet pipe 43 in its own radial direction. The rotating water outlet pipe 43 can rotate around the axial water supply branch pipe 42. The rotating water outlet pipe 43 is installed on the bottom surface of the bearing seat 22. The bearing seat 22 has three protrusions 23 on the bottom surface with corresponding water inlets 231. The rotating water outlet pipe 43 is connected to the three water inlets 231 in sequence through the water inlet pipe 44. The side wall and top wall of the protrusion 23 are provided with water spray holes (not shown in the figure). The above-mentioned water pump, the central rotating shaft 10, the radial water supply branch pipe 41, the axial water supply branch pipe 42, the rotating water outlet pipe 43 and the water inlet pipe 44 serve as a water supply mechanism.

[0028] After the tableware fixing mechanism 20 is folded, the user can click the cleaning start button on the touch panel to trigger the cleaning start instruction. The main control unit sends the cleaning start instruction to the controller of the drum dishwasher 100. After receiving the instruction, the controller drives the central shaft 10 to rotate by the rotary motor, starts the water pump, and supplies water to each protrusion 23 and the nozzle located on the wall of the cleaning chamber, so that: the protrusion 23 sprays the inner wall of the dirty tableware 24 that covers the protrusion 23 upside down through the water spray hole on its outer surface, and the nozzle sprays the outer wall of the dirty tableware 24. In this embodiment, hot water is used for spraying, and hot water is used to dissolve stains. In this embodiment, while the dishwasher sprays the dirty tableware 24 on some of the tableware fixing mechanisms 20, it also sprays the clean tableware on other tableware fixing mechanisms 20.

[0029] like Figure 3 As shown, the drum-type dishwasher 100 has upper and lower accommodating grooves 120 respectively formed on the left and right side walls of the cleaning cavity, and a disinfection lamp mechanism is provided in the accommodating grooves 120. Figure 8 As shown, the disinfection lamp mechanism includes a mounting frame 35 and a partition 31. The partition 31 is formed by Fig. 9 The rotating shaft 34 is fixed in the mounting frame 35. The front of the partition 31 is provided with a disinfection lamp 30, and the mounting frame 35 is provided with a motor 32, the motor 32 is connected to the left end of the crank structure 33, and the right end of the crank structure 33 is connected to the partition 31. In the process of spraying the tableware 24, the front of the partition 31 faces outside the cleaning chamber, as shown in FIG. Figure 2 As shown, the disinfection lamp 30 faces out of the cleaning chamber and the partition 31 separates the disinfection lamp 30 from the cleaning chamber. In this way, the disinfection lamp 30 will not be splashed by water droplets. After washing the tableware 24, the controller controls the motor 32 to drive the crank structure 33 to rotate, thereby driving the partition 31 to flip around the rotation axis 34 until its front side faces the cleaning chamber, so that the disinfection lamp 30 also faces the cleaning chamber. Figure 3 The two disinfection lamp mechanisms on the left are in the state shown. A position sensor is provided on the back of the mounting frame 35 (not shown in the figure), which is located on the flipping path when the partition 31 flips to the front side facing the cleaning chamber. If the partition 31 rotates to the right position, it will hit the right position switch, and the motor 32 will stop driving the partition 31. At this time, the disinfection lamp 30 faces the cleaning chamber. If it is not necessary to disinfect all the tableware on the tableware fixing mechanism 20, only one side of the partition 31 can be driven to flip so that the corresponding disinfection lamp 30 faces the cleaning chamber. Figure 3As shown, only the disinfection lamp 30 on the left side faces the inside of the cleaning chamber, while the disinfection lamp 30 on the right side faces the outside of the cleaning chamber, and then the central rotating shaft 10 is driven by the rotating motor to rotate, so that the tableware fixing mechanism 20 that needs to be disinfected moves to the position of the disinfection lamp 30 facing the cleaning chamber for disinfection. If it is necessary to disinfect the tableware on all the tableware fixing mechanisms 20, all the disinfection lamps 30 are directed to the inside of the cleaning chamber, and then the central rotating shaft 10 is driven by the rotating motor to rotate, so that the tableware on each tableware fixing mechanism 20 can be irradiated by the disinfection lamp 30. After the tableware 24 is disinfected, the motor 32 drives the crank structure 33 to reverse, thereby driving the partition 31 to reversely flip and reset. A reset stroke switch 36 is provided on the front of the mounting frame 35, and the reset stroke switch 36 is located on the flipping path from the partition 31 reversely flipping to the front facing the outside of the cleaning chamber. If the partition 31 rotates and returns to the initial position, it will hit the reset stroke switch 36, and the motor 32 stops driving the partition 31. In this embodiment, the reset stroke switch 36 and the in-position stroke switch are both position sensors.

[0030] If the user needs to take out the cleaned dishes 24, he can click the dish removal button on the touch panel to trigger the dish removal command. The main control unit sends a dish removal command to the controller of the drum dishwasher 100. After receiving the dish removal command, the controller controls the rotary motor to drive the central shaft 10 to rotate so that the dish fixing mechanism 20 with the clean dishes placed thereon rotates to the dish retrieval window 110. The electric cover opens the dish retrieval window 110, and then the motor 291 drives the moving rod 26 to move radially, thereby driving the supporting seat 22 to rotate upward until it is placed flat on the dish retrieval window 110, as shown in FIG. Figure 1 As shown, the user can take out the tableware 24.

[0031] In this embodiment, the controller is electrically connected to the rotating motor, the motor 291, the electric cover, the camera, the water pump, the motor 32, the disinfection lamp 30, the in-position travel switch and the reset travel switch 36 respectively.

[0032] The bearing seat 22 and the back bar 25 of this embodiment are linked, and the bearing seat 22 is rotated to drive the back bar 25 to move along the guide rail 222 to the back of the tableware 24. In a non-preferred embodiment, the linkage between the bearing seat 22 and the back bar 25 can be cancelled, and the user can manually push the back bar 25 to move along the guide rail 222 to the back of the tableware 24 to stop.
