Description

Technical Field

[0001] The utility model relates to the technical field of refrigerators, in particular to a refrigerator with an anti-blocking drainage structure. Background Art

[0002] In order to smoothly discharge the condensed water in the refrigerator box out of the refrigerator, a refrigerator with an upper storage and lower freezing structure usually uses a drain pipe structure. Therefore, the drain pipe is connected to the refrigerator box and connected to the outside world, so that the condensed water in the refrigerator box can be discharged to the outside through the drain pipe.

[0003] A traditional refrigerator has a water collection tank formed on the lower half of the inner wall of the refrigeration area, and a drain pipe is provided on one side of the water collection tank. Water droplets formed on the inner wall of the refrigerator will roll into the water collection tank and then be discharged through the drain pipe. However, during daily use, food crumbs and dust in the refrigerator will also fall into the water collection tank and move into the drain pipe with the water droplets, which may cause blockage of the drain pipe in severe cases. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a refrigerator with an anti-blocking drainage structure, which has the effect of preventing the refrigerator drain pipe from being blocked.

DETAILED DESCRIPTION

[0022] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0023] Example:

[0024] Reference Figures 1 to 4 The utility model discloses a refrigerator with an anti-blocking drainage structure, comprising a box body 1 and two doors 2 hinged to one side of the box body 1. A water collecting plate 3 is fixedly connected to the inner wall of the box body 1, and the cross section of the water collecting plate 3 is L-shaped. Water droplets generated on the inner wall of the box body 1 can flow into the water collecting plate 3. This process requires the inner wall of the box body 1 to form a guide groove, which is a prior art and will not be described here.

[0025] A drainage pipe 4 is fixedly provided on the inner wall of the box body 1, a filter screen 5 is fixedly connected to the upper inner half of the water collecting plate 3, and the drainage pipe 4 is located between the filter screen 5 and the bottom surface of the water collecting plate 3. After water droplets and debris enter the water collecting plate 3, the water droplets pass through the filter screen 5 and move to the bottom surface of the water collecting plate 3, and are discharged from the box body 1 through the drainage pipe 4, and the debris remains on the top of the filter screen 5. A cleaning component 6 is provided on the top of the filter screen 5.

[0026] The cleaning assembly 6 includes two accommodating chambers 61 opened in the opposite side walls of the box body 1, and a lead screw 62 is rotatably connected between the two accommodating chambers 61, and a portion of the lead screw 62 is located above the filter screen 5. The outer circumference of the lead screw 62 is provided with two sections of threads with opposite rotation directions, and a screw block 63 is threadedly connected at the two sections of the thread on the outer circumference of the lead screw 62. The bottom surface of the screw block 63 is in contact with the top of the filter screen 5, and the side wall of the screw block 63 is in contact with the side wall of the water collecting plate 3. When the lead screw 62 rotates, the screw block 63 can only move horizontally.

[0027] Collecting parts 65 are provided at both ends of the water collecting plate 3 , and a driving part 64 is provided in the accommodating cavity 61 .

[0028] The driving part 64 includes a sliding rod 641 that is slidably arranged on one side of the accommodating chamber 61, and a straight rack 642 is fixedly connected to one end of the sliding rod 641 located in the accommodating chamber 61. A gear 643 is fixedly sleeved on the outer peripheral surface of the lead screw 62, and the straight rack 642 is meshed with the gear 643. A first spring 644 is fixedly connected between the straight rack 642 and the inner side wall of the accommodating chamber 61. When the first spring 644 is in a natural state, the sliding rod 641 partially extends to the outside of the box body 1. When the box door 2 is closed, the box door 2 will squeeze the sliding rod 641, so that the sliding rod 641 is retracted into the box body 1, and the first spring 644 is compressed. The first spring 644 is a hard spring and will not be twisted or deformed.

[0029] In the initial state, the door 2 is closed, the first spring 644 is compressed, and the two screw blocks 63 are fitted. When the door 2 is opened, a gap is generated between the door 2 and the side wall of the box body 1, and the sliding rod 641 is no longer squeezed by the door 2, and slides under the restoring force of the first spring 644, and the sliding rod 641 drives the spur rack 642 to move, the spur rack 642 drives the gear 643 to rotate, and the gear 643 drives the lead screw 62 to rotate, thereby driving the two screw blocks 63 to move in reverse, and the screw block 63 pushes the debris on the top of the filter 5 to move.

[0030] The collecting part 65 includes a collecting box 651 fixedly connected to the inner wall of the box body 1, and the top of the collecting box 651 is coplanar with the top surface of the filter screen 5. The top of the collecting box 651 is open, and a baffle 652 is hinged on the upper half of the inner wall of the collecting box 651. A moving block 653 is movably sleeved on the outer peripheral surface of the lead screw 62, and the moving block 653 can rotate or slide relative to the lead screw 62.

[0031] A second spring 654 is fixedly connected between the moving block 653 and the inner wall of the box body 1, and a connecting rod 655 is hinged at the bottom of the moving block 653, and the bottom end of the connecting rod 655 is hinged to the top of the baffle 652. When the second spring 654 is in a natural state, the baffle 652 is in a horizontal state, and the side wall of the baffle 652 fits the inner wall of the collection box 651, completely shielding the collection box 651 to prevent the smell in the collection box 651 from escaping.

[0032] When the screw block 63 moves, it pushes the moving block 653 to move, and the moving block 653 drives the connecting rod 655 to move, and the connecting rod 655 drives the baffle 652 to rotate, so that the collection box 651 is exposed, and finally the debris is pushed into the collection box 651.

[0033] The implementation principle of the above embodiment is:

[0034] In the initial state, the box door 2 is closed, the first spring 644 is compressed, and the two screw blocks 63 are fitted together. The water droplets generated on the inner wall of the box body 1 can flow into the water collecting plate 3, pass through the filter screen 5 and move to the bottom surface of the water collecting plate 3, and are discharged from the box body 1 through the drain pipe 4. The debris cannot pass through the filter screen 5 and will flow to the top of the filter screen 5.

[0035] When the box door 2 is opened, a gap is generated between the box door 2 and the side wall of the box body 1, and the sliding rod 641 is no longer squeezed by the box door 2 and slides under the restoring force of the first spring 644. The sliding rod 641 drives the spur rack 642 to move, and the spur rack 642 drives the gear 643 to rotate, and the gear 643 drives the lead screw 62 to rotate, thereby driving the two screw blocks 63 to move in reverse, and the screw block 63 pushes the debris on the top of the filter screen 5 to move until the screw block 63 contacts the moving block 653 and pushes the moving block 653 to move, and the moving block 653 drives the connecting rod 655 to move, and the connecting rod 655 drives the baffle 652 to rotate, thereby exposing the collection box 651, and finally the debris is pushed into the collection box 651.

[0036] When the door 2 is closed, the door 2 presses the sliding block to restore the sliding block to its original position, thereby restoring the baffle 652 and the screw block 63 to their original positions.

[0037] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
