Description
Technical Field
[0001] The invention relates to the technical field of toilets, in particular to an overflow assembly and a toilet. Background Art
[0002] Under normal operation, the working water level of the toilet tank is lower than the preset value. However, after long-term use or damage to the water inlet valve, the final water level of the toilet tank will be too high. At this time, the overflowing water often enters the toilet pot through the overflow channel and is discharged. However, in pursuit of aesthetics, the height of the existing toilet tanks is getting lower and lower, and even many styles have the top of the tank flush with the top of the toilet seat. In this type of toilet, the height of the top of the tank may even be lower than the toilet pot, and the above overflow structure cannot be used. Once overflow occurs, it is likely to cause damage to the toilet, soaking of the floor, and even electrical safety. Summary of the invention
