Filed: 2019-07-26
Abstract: The present invention relates to a fish tank with an automatic cleaning function, in which residues stacked on the bottom of the fish tank can be cleaned simultaneously with water exchange of the fish tank. According to the present invention, when water is poured into a water tank (100) for pouring water, the water comes down along a wall (200_a) of the fish tank to arrive at the highest point (300_H) of a wide slope (300). As this water flows along the wide slope (300) and passes through a low place (300_L) of the wide slope, the residues are collected on a narrow slope (400). Even on the narrow slope (400), the residues at the high place (400_H) of the narrow slope flow to the lower side (400_L) of the narrow slope, where a discharge pipe (500) is located, to be collected. At this time, when the siphon principle operates by the height of the supplied water, the residues collected at the lower side of the narrow slope (400_L) are discharged out of the fish tank through the discharge pipe (500). Moreover, the water level of the fish tank is adjusted by adjusting the length of a fish tank water level control tube (500_a) outside the fish tank.
