[0002] Dishwashers are devices that automatically wash tableware such as bowls, chopsticks, plates, dishes, knives, forks, etc. Fully automatic dishwashers on the market can be divided into two categories: home use and commercial use. Home use fully automatic dishwashers are only suitable for families, and they mainly include cabinet type, table type, integrated sink type, and integrated type. Commercial dishwashers can be divided into five categories according to their structure: cabinet type, hood type, basket type, belt type, and ultrasonic type. They reduce the labor intensity of cooks in restaurants, hotels, and canteens of government agencies, improve work efficiency, and promote cleanliness and hygiene.

[0003] Dishwashers have gradually become one of the daily appliances of every family. Most dishwashers are assembled from multiple parts. In the manufacturing process of dishwashers, the parts need to be manufactured separately first, and then the operators assemble the parts together to form a dishwasher. Before the dishwasher is packaged and sold, it needs to be tested for water.

[0004] When the existing dishwasher water inspection test line is running, the conveyor belt has to be started and stopped frequently. During this process, the dishwasher is prone to side slippage, causing the test probe and the dishwasher to be misaligned, greatly affecting the detection effect and accuracy of the water inspection test.

[0005] In summary, there is a need for a dishwasher annular dynamic water detection test line that can improve the detection effect and accuracy of water detection tests. Summary of the invention

[0006] The present invention aims to overcome the problem in the prior art that when a dishwasher water detection test line is running, a conveyor belt has to be frequently started and stopped, during which the dishwasher is prone to side slippage, thereby causing a misalignment between the test probe and the dishwasher, greatly affecting the detection effect and accuracy of the water detection test. The present invention provides a dishwasher annular dynamic water detection test line that can improve the detection effect and accuracy of the water detection test.

One side in the middle is connected to the bottom surface of the baffle slide groove by a spring, and the other side of the baffle and the side away from the bottom edge of the U-shaped frame is provided with a guide slope, and a wire outlet push rod is also installed on the machine tool, and the wire outlet push rod is movably connected to the machine tool, and the wire outlet push rod is placed on the side of the conveyor belt and above the placement plate, and the wire outlet push rod is arranged on the side away from the opening of the U-shaped frame, and a connecting plate is installed on the wire outlet push rod, and a baffle control rod is fixed on the connecting plate, and a side channel matching the baffle control rod is provided on the side wall of the baffle slide groove, and the baffle control rod and the side channel are movably connected.

[0008] The placement plate is used to place the dishwasher to be tested. The U-shaped frame on the placement plate acts as a limiter for the dishwasher. The dishwasher can be moved from the opening of the U-shaped frame to the inner side of the U-shaped frame. When the dishwasher passes through the opening of the U-shaped frame, according to the pressure decomposition characteristics of the guide slope 1, the dishwasher will automatically press the other end of the baffle into the baffle slide groove.
