Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of refrigerators, in particular to a drainage structure for a refrigerator. Background Art
[0002] A refrigerator is a device used for low-temperature preservation of items. During use, a water storage tank is usually arranged at the bottom of the refrigerator to collect and drain the liquid water melted inside the refrigerator, so as to prevent the liquid water from accumulating inside the refrigerator and damaging the goods.
[0003] When the existing drainage structure of a refrigerator is in use, the filter screen at the end of the drainage port is usually fixedly arranged and cannot adjust the height position. When the liquid level inside the water storage tank is too high, the filter screen will be soaked. When storing some ingredients such as meat, the melted blood and meat residues will be soaked inside the water storage tank together, accelerating the spoilage and deterioration and easily generating peculiar smells.
[0004] Therefore, aiming at the problem that the height position of the filter screen cannot be adjusted when the existing drainage structure of a refrigerator is in use, a drainage structure for a refrigerator can be designed. By the operation of a driving motor, the rotating shaft drives the chuck to rotate synchronously, so as to wind up the pulling rope. The end of the pulling rope will drive the clamping block and the sliding block to move upward, so as to raise the height of the filter box and prevent the filter residue from rotting and deteriorating when soaked in the condensed water of the water collection tank. Summary of the Utility Model

[0007] Preferably, by setting a driving motor, its output end will drive the rotating shaft to rotate during operation, and the rotating shaft drives the chuck to rotate synchronously, thereby winding the pulling rope. The end of the pulling rope will drive the chuck and the slider to move upward, thereby raising the height of the filter box, avoiding the rotting and deterioration of the filter residue soaked in the condensed water in the water collection tank, and solving the problem that the filter screen inside the water storage box of the existing drainage structure of the refrigerator is fixedly installed and cannot adjust the height. When the water level in the water storage tank is relatively high, the filter residue will be soaked in water and rot and deteriorate.
[0008] Preferably, the top surface of the drain pipe is connected to the bottom plate of the refrigerator. A filter screen is arranged at the corresponding position on the upper surface of the bottom plate of the refrigerator corresponding to the top of the drain pipe. By setting the filter screen, the water entering the drain pipe can be filtered, thereby reducing impurities from entering the inside of the drain pipe and discharging them on the surface of the filter box.
[0009] Preferably, six fixing bolts distributed in a circle are arranged at the edge position of the upper surface of the filter screen. The filter screen is connected to the bottom plate of the refrigerator through the fixing bolts. By setting the fixing bolts, it is convenient for the staff to quickly disassemble and assemble the filter screen, facilitating cleaning and replacement during daily use.
[0010] Preferably, an L-shaped block is placed on the front side of the upper surface of the water collection tank. A handle is installed on the top surface of the L-shaped block, and a threaded mounting seat is installed on the rear side surface of the L-shaped block. A cleaning rod is installed on the bottom surface of the threaded mounting seat. Brush hairs are arranged on both the front side surface and the bottom surface of the cleaning rod.

[0011] Preferably, a moving groove is arranged at the upper position of the outer surface of the water collection tank. A magnetic strip is adhered to the inner surface of the moving groove. A magnetic bead is installed on the rear side surface of the long rod of the L-shaped block. By setting the moving groove and the magnetic bead, during the movement of the L-shaped block, the magnetic bead will be adsorbed by the magnetic strip inside the moving groove, and the moving groove plays a limiting role on the magnetic bead, improving the stability during movement.
[0012] Preferably, fixing pieces are installed on the opposite inner surfaces of the collar. Adjusting screws are threadedly connected through the opposite surfaces of the two fixing pieces. By rotating the adjusting screws, the collar can be contracted, thereby clamping the drain pipe to achieve the purpose of adapting to drain pipes of different diameters.
[0013] Preferably, a limit nut is threadedly connected to the right end position of the outer surface of the adjusting screw. The collar is made of acrylic. By setting the limit nut, after adjusting the position of the collar, the limit nut is screwed onto the end of the adjusting screw, which can limit the collar and prevent the drain pipe from falling off due to the expansion of the collar during use. Moreover, the acrylic collar has high flexibility and can produce large elastic deformation.
[0014] Advantages of the present utility model:
[0015] 1. By setting the driving motor, during operation, its output end drives the rotating shaft to rotate, and the rotating shaft drives the chuck to rotate synchronously, thereby winding the pulling rope. The end of the pulling rope drives the block and the slider to move upward, thus raising the height of the filter box and preventing the filter residue from rotting and deteriorating when soaked in the condensed water in the water collection tank. This solves the problem that in the existing drainage structure of the refrigerator, the filter screen inside the water storage box is fixedly installed and cannot adjust the height. When the water level in the water storage tank is high, the filter residue will be soaked in water and rot and deteriorate. BRIEF DESCRIPTION OF THE DRAWINGS
