[0043] Embodiment 1

[0044] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, this embodiment provides a protection mechanism, including a frame 10, a protection unit 11 and a detector 104. Among them, a slideway 1021 is arranged on the frame 10, and the protection unit 11 includes a fixing frame 111 horizontally slidably arranged on the slideway 1021 and a bowl-blocking grille 112 arranged on the fixing frame 111. The detector 104 is arranged on the frame 10, and the detection end of the detector 104 is arranged on one end of the slideway 1021. The fixing frame 111 is provided with a sensing sheet 11121 for sensing and detecting with the detector 104. In an optional embodiment, the detector 104 is an ITR1203DT50A / TB infrared slot-type photoelectric switch.

[0045] Specifically, the protection mechanism is arranged at the outlet of the dishwasher, and a conveying device for conveying tableware is arranged in the dishwasher. One end of the bowl retaining grille 112 is horizontally arranged on the fixed frame 111, and the other end is vertically arranged toward the conveying device. When in use, the tableware is neatly arranged on the conveying device. When the tableware is conveyed to the outlet of the dishwasher, it will be blocked by the bowl retaining grille 112. At this time, the tableware will generate a horizontal thrust on the bowl retaining grille 112, thereby driving the fixed frame 111 to move. The induction sheet 11121 on the fixed frame 111 moves along with the fixed frame 111, and then the induction sheet 11121 is sensed by the detector 104, so that the conveying device stops conveying and cleans the tableware. After the tableware is cleaned, the tableware can be taken out and the fixed frame 111 is reset, so that the dishwasher can carry out a new round of tableware cleaning.

[0046] In this way, by setting a protective mechanism at the outlet of the dishwasher, using the detector 104 and the sensor sheet 11121 to automatically detect the position of the tableware conveying and automatically control the start or stop of the conveying device, the conveying device automatically stops when the tableware is conveyed to the outlet of the dishwasher, which solves the problem that the traditional dishwasher has high requirements for the speed of manual tableware picking, and effectively reduces the burden of manual labor. The bowl retaining grille 112 is used to block the tableware to prevent the tableware from falling and being damaged due to continued displacement due to inertia after the conveying device stops, and the movement trajectory of the bowl retaining grille 112 is always on the same horizontal plane, which improves the gap accuracy between the bowl retaining grille 112 and the conveying device, reduces the possibility of tableware falling, plays a good protective role for the tableware, and prevents the tableware from falling into the dishwasher and jamming the components inside the dishwasher, thereby causing the dishwasher to malfunction, which can effectively extend the service life of the dishwasher.

[0047] like Figure 1 and Figure 3 As shown, in this embodiment, a buffer spring 11111 is arranged between the fixing frame 111 and the frame body 10 , and the direction of the deformation elastic force of the buffer spring 11111 is arranged parallel to the moving direction of the fixing frame 111 .

[0048] Specifically, when tableware is transported to the exit end of the dishwasher, the bowl retaining grille 112 will block the further movement of the tableware. The tableware will generate a horizontal thrust on the bowl retaining grille 112, thereby pushing the fixed frame 111 to move. At this time, the buffer spring 11111 is compressed under the action of the force. After the tableware is cleaned and taken away, the thrust of the tableware on the bowl retaining grille 112 disappears, and the buffer spring 11111 recovers its deformation, thereby driving the fixed frame 111 to automatically reset, so that the dishwasher can carry out a new round of cleaning.

[0049] In addition, the buffer spring 11111 can play a certain buffering role in the movement of the fixed frame 111. When the tableware is transported to the outlet end of the dishwasher and is blocked by the bowl retaining grille 112, the bowl retaining grille 112 moves back and forth under the action of the buffer spring 11111, thereby avoiding damage to the tableware due to rigid collision with the tableware and providing good protection for the tableware.

[0050] like Figure 3 As shown, in this embodiment, a fixed column 1111 on which a buffer spring 11111 is mounted is provided on the fixed frame 111, and one end of the fixed column 1111 is provided on the frame body 10. When the fixed frame 111 moves under the thrust generated by the tableware, the buffer spring 11111 mounted on the fixed column 1111 is compressed; alternatively, a gap is provided between one end of the fixed column 1111 and the frame body 10. When the fixed frame 111 moves under the thrust generated by the tableware, the fixed column 1111 abuts against the frame body 10, thereby compressing the buffer spring 11111 mounted on the fixed column 1111.

[0051] like Figure 3 As shown, in this embodiment, the fixed column 1111 is a threaded rod, and a nut 11112 for adjusting the tightness of the buffer spring 11111 is provided on one end of the threaded rod. By adjusting the tightness of the buffer spring 11111, the buffering force of the buffer spring 11111 on the fixed frame 111 can be adaptively adjusted according to different sizes of tableware, thereby improving the protection effect on the tableware.

[0052] like Figure 1 , Figure 2 and Figure 4 As shown, in this embodiment, the slide 1021 is a strip hole, and at least one sliding column 1112 sliding in the strip hole is provided on the fixed frame 111, and the fixed frame 111 is connected to the frame body 10 through the sliding column 1112, and the sensing sheet 11121 is provided on the sliding column 1112, and when the fixed frame 111 moves, the sensing sheet 11121 is driven to move, thereby sensing the detector 104.

[0053] like Figure 1 and Figure 2 As shown, in this embodiment, a waist-shaped groove 1022 for installing the detector 104 is provided on the frame 10 relative to the slide 1021. The detector 104 can adjust the installation position along the length direction of the waist-shaped groove 1022, so as to be adaptively adjusted according to different sizes of tableware to improve the accuracy of the detector 104 and the sensor sheet 11121 in detecting the position of the tableware.

[0054] like Figure 1As shown, in this embodiment, the frame 10 includes an inner shell 102 for sliding installation of a fixing frame 111 and an outer shell 101 covered on the outside of the inner shell 102, and the slide 1021 is set on the inner shell 102, and the waist-shaped groove 1022 is also set on the inner shell 102. The fixing frame 111 slides along the slide 1021 through the sliding column 1112 and is connected to the inner shell 102. The detector 104 is installed on the waist-shaped groove 1022, and the outer shell 101 is covered on the outside of the inner shell 102 to play a protective and aesthetic role.

[0055] like Figure 8 As shown, in this embodiment, two rotating members 103 are symmetrically arranged at the bottom of the rack 10. The rack 10 is rotatably arranged on the frame 20 of the dishwasher through the two rotating members 103. The rack 10 can be turned over to clean the residues in the dead corners inside the dishwasher and to facilitate maintenance. At the same time, if tableware is stuck, the rack 10 can be turned over to take out the tableware to avoid malfunction of the dishwasher.

[0056] Embodiment 2

[0057] Please refer to Figure 7 and Figure 8 As shown, the second aspect of this embodiment further provides a dishwasher, including the protection mechanism described in the first embodiment.

[0058] In this embodiment, the protection mechanism is arranged on the outlet end frame 20 of the dishwasher. The rotating member 103 of the protection mechanism is a hinged piece with a U-shaped groove. The U-shaped groove is used to avoid the frame 20 of the dishwasher when the frame 10 is turned over. One end of the hinged piece is hingedly arranged on the frame 20 of the dishwasher, and the other end of the hinged piece is hingedly arranged on the frame 10 of the protection mechanism. When the dishwasher is working, the cover frame 10 plays a protective role (such as Figure 7 When the dishwasher stops working, the frame 10 can be opened to clean and repair the dead corners inside the dishwasher (as shown); Figure 8 shown).

[0059] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
