[0020] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.
[0021] Reference Figure 1-3A one-way anti-backflow structure for a commercial ice maker includes a drain pipe 1, a filter box 2 is fixedly connected to the upper end of the drain pipe 1, and a one-way box 3 is fixedly connected to the lower end. A fixed plate 4 is fixedly arranged in an inclined manner in the filter box 2, a sliding plate 5 is slidably arranged above the fixed plate 4, and the bottom surface of the sliding plate 5 is in contact with the top surface of the fixed plate 4. A plurality of drainage holes 6 are arranged in an array on the fixed plate 4 and the sliding plate 5. A stopper 7 is fixedly connected to one side of the inclined upper end of the sliding plate 5. A stopper 8 is slidably arranged on the side of the filter box 2 located on the side of the stopper 7 facing away from the sliding plate 5. A plurality of springs 9 are arranged in an array between the baffle plate 8 and the side wall of the filter box 2. A button 10 for pushing the sliding plate 5 is installed on the outside of the filter box 2. By pushing the sliding plate 5 with the button 10, the drainage holes 6 on the sliding plate 5 and the drainage holes 6 on the fixed plate 4 change from overlapping to staggered, thereby realizing the cutting off and cleaning of impurities in the filter box 2. By cooperating with the spring 9 and the baffle plate 8, the automatic return of the sliding plate 5 is realized. Compared with the existing device, the problem of possible blockage of the pipeline due to the possible carrying of some impurities during drainage is avoided, and the stability of the device is improved.
[0022] Reference Figure 1-3 A tilted plate 11 is fixedly connected to the top of one side of the filter box 2, and the tilted plate 11 is located directly above the stopper 7, so as to guide the water and prevent the water from entering the spring 9 as much as possible.
[0023] The side walls of the filter box 2 are fixedly provided with slide grooves 12 on both sides just below the inclined plate 11, and both sides of the baffle 8 extend into the slide grooves 12. The baffle 8 is limited by the slide grooves 12 to prevent the baffle 8 from tilting and moving with the block 7, resulting in uneven force on the spring 9.
[0024] The movable range of the sliding plate 5 is larger than the diameter of the drainage hole 6 , thereby achieving the cutting and cleaning of impurities in the drainage hole 6 .
[0025] Reference Figure 1 , Figure 4 A fixing ring 13 is fixedly connected inside the one-way box 3, and a hinged plate 14 is hinged on one side of the bottom surface of the fixing ring 13. The side of the hinged plate 14 away from the hinge is magnetically connected to the fixing ring 13, so as to realize automatic closing of the hinged plate 14 when there is no water, thereby preventing foreign matter or animals from entering the ice maker in reverse and contaminating the ice maker. The upper end of the fixing ring 13 is beveled to prevent foreign matter from staying on the fixing ring 13.
[0026] The side wall of the one-way box 3 below the hinge plate 14 is fixedly connected to the limit block 15. When the bottom end of the hinge plate 14 is in contact with the limit block 15, the hinge plate 14 is tilted at an angle of no more than 45° to avoid the hinge plate 14 being unable to return to its original position due to excessive magnetic attraction.
[0027] The drain pipe 1 is N-shaped to form a water-sealed bend, thereby blocking odor and avoiding pollution to the inside of the ice maker. The bend angle of the drain pipe 1 is between 30° and 60°, which facilitates the water discharge of the drain pipe 1 and avoids the angle being too small to cause some impurities to remain at the bend.
[0028] Working principle:
[0029] The one-way anti-backflow structure of the commercial ice maker is used. When water enters the drain pipe 1, impurities in the water stay on the surface of the sliding plate 5 in the filter box 2. When a large amount of impurities accumulate, the button 10 is pressed to drive the sliding plate 5 to slide. The drainage holes 6 on the sliding plate 5 are staggered with the drainage holes 6 on the fixed plate 4. The impurities on the sliding plate 5 are cut off and cleaned. The processed impurities follow the water into the return bend in the middle section of the drain pipe 1. At this time, a water-sealed water bend is formed. The water then enters the rear section of the drain pipe 1 and enters the one-way box 3. The hinged plate 14 is stressed and rotates, and the water is discharged from the drain pipe 1. After completion, the hinged plate 14 is attracted by the magnet and automatically closes. The above is the entire use process of the one-way anti-backflow structure of the commercial ice maker.
[0030] The above is only a preferred specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed in the present application according to the technical solution and utility model concept of the present application, which should be covered by the protection scope of the present application.
