Description

Technical Field

[0001] The utility model relates to the technical field of dishwashers, in particular to a dishwasher cleaning structure. Background Art

[0002] A dishwasher is a device that automatically washes tableware such as bowls, chopsticks, plates, dishes, knives, forks, etc. The fully automatic dishwashers on the market can be divided into two categories: household and commercial. Household fully automatic dishwashers are only suitable for families, and they are mainly cabinet-type, table-top, sink-integrated and integrated.

[0003] When the existing dishwasher is in use, the bowls are rinsed and cleaned through the spray arms installed up and down inside. However, when the spray arms are not spraying water, the nozzles are easily blocked by oil and garbage, which affects the use of the spray arms and reduces the cleaning effect. Therefore, we propose a dishwasher cleaning structure to solve the above problem. Utility Model Content

The fixed column 41 can facilitate the limiting support of the fixed seat 42. A connecting column 43 is inserted inside the fixed seat 42, and one end of the connecting column 43 is fixedly connected to a driving disk 44, and the other end of the connecting column 43 is fixedly connected to a pushing block 45. The driving disk 44 can facilitate the water pushing effect, and the pushing block 45 can facilitate the pushing effect of the protective plate 53. A reset spring 46 is welded between the fixed seat 42 and the driving disk 44. The elastic force of the reset spring 46 itself can push the driving disk 44 to reset it.

[0029] Further, see Figure 3 and Figure 4 It can be known that the connecting column 43 is set to be cylindrical, and a circular hole compatible with the connecting column 43 is opened inside the fixing seat 42. Through the circular hole opened inside the fixing seat 42, the connecting column 43 can move in the circular hole, which plays the role of limiting and guiding the connecting column 43.

[0030] Further, see Figure 2 and Figure 3 It can be known that the side of the driving plate 44 is in contact with the inner wall of the guide frame 47, and the guide frame 47 is fixedly connected to the inner wall of the plug-in tube 31.

[0033] Working principle: When the utility model is in use, when the dishwasher body 1 is in use, according to the attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 and attached Figure 4, by inserting the plug-in pipe 31 into the water delivery pipe 2, the water delivery pipe 2 supplies water to the inside of the cleaning spray arm 32, and the water can be sprayed into the dishwasher body 1 through the cleaning spray arm 32 to clean the bowls. At the same time, when the water delivery pipe 2 is filled with water into the plug-in pipe 31, the water will impact the surface of the driving plate 44. At this time, the driving plate 44 will drive the connecting column 43 to move telescopically in the fixing seat 42, compressing the reset spring 46. When the driving plate 44 is moved out of the guide frame 47, water can enter the cleaning spray arm 32. At the same time, during the movement of the connecting column 43, In the process, the push block 45 will push the two sets of protection plates 53 to move, and the protection plates 53 will cause the hinge block 52 to rotate between the fixed block 51. At this time, the protection plate 53 drives the protection frame 55 to expand, so that the cleaning spray arm 32 can spray water. When the water supply pipe 2 stops supplying water, the elastic force of the reset spring 46 can make the connecting column 43 drive the driving plate 44 to reset, so that the push block 45 is away from the two sets of protection plates 53. At this time, the elastic force of the torsion spring 54 can make the hinge block 52 drive the protection plate 53 to reset, so as to shield and protect the nozzle on the surface of the cleaning spray arm 32.
