Description

Water level sensor and automatic water filling bathtub with same

Technical Field

The utility model relates to a bathroom equipment field, especially a water level sensor and have automatic bathtub that fills of this inductor.

Background

When the bathtub is used, the bathtub is large in volume and limited in water inflow, so that water is required to be filled for a period of time, and the bathtub is short in a few minutes and long in a dozen or more minutes. If people wait for the bathroom all the time, the time is wasted, if not, excessive water is easily supplied due to forgetting, hot water is wasted, and even the bathroom is flooded due to the fact that the bathtub overflows in short time.

At present, the invention has Chinese patents: an automatic control method for discharging water from bathtub (application publication No. CN 105276821A) is to indirectly control the water level of bathtub by controlling the water inflow. The disadvantages are that: different bathtubs have different water level heights corresponding to the same water inflow due to different sizes and shapes, and the water level of the bathtub is more concerned by the owners. For example, adults and children have different requirements on water levels, people are fat and thin and have different requirements on water levels, and the water levels are invariably only caused to waste water or be insufficient. If the owner determines the corresponding data of the water inlet volume and the water level according to the actual size of the bathtub, the owner is obviously unscientific and difficult to accurately determine.

The Chinese utility model patent: a bathtub water level control device (application publication number: CN 201570214U) controls the opening and closing of a water inlet valve by arranging a plurality of water level sensors on the bathtub wall. The disadvantage is that holes need to be formed in the bathtub, which affects the appearance, has poor universality and is useless for most bathtubs and a large number of installed bathtubs. There is no continuity in controlling the water level, limited by the number of openings.

There is also a way to control the water level of the bathtub by a communicating device (for example, patent "Bath water level control system" US 4258444A), and this technology is troublesome to install, cannot be popularized, and cannot be used for reforming the existing bathtub.
