Automatic control method for water discharge of bathtub

Abstract

The invention discloses an automatic control method for water discharge of a bathtub. The automatic control method is characterized in that a gas water heater is used to realize automatic control for water discharge of the bathtub; and a water flow control device is arranged on a bathtub water discharge joint point of a hot water pipe of the gas water heater; the water flow control device is controlled by control signals provided by an operation displayer and a water flow sensor, opens the hot water pipe to discharge water out of the bathtub according to set time provided by the operation displayer and automatically close the hot water pipe to stopping discharging water out of the bathtub according to a water flow accumulated signal provided by the water flow sensor. Compared with the prior art, the control method disclosed by the invention has the advantages as follows: the bathtub can be opened in a timing manner for water discharge, in addition, water discharge and water stopping of the bathtub are not required to be operated manually and water utilization of other joint points of the gas water heater are not influenced after water discharge of the bathtub is completed.

Description

technical field [0001] The invention relates to a bathtub automatic water injection technology, in particular to an automatic bathtub water discharge control method. Background technique [0002] With the improvement of living standards, users have higher and higher requirements for bathing comfort. At present, many intelligent water heaters have a "bathtub" bathing function. Time will seriously affect the comfort of bathing. [0003] A Chinese utility model patent with a publication number of CN202361647Y discloses a gas water heater that can automatically turn off the water with a bathtub mode, including a heat exchanger, and a burner assembly is arranged below the heat exchanger. The water inlet pipe and the water outlet pipe are connected to the burner, and it is characterized in that: a water flow sensor and an automatic water shut-off valve are provided on the water inlet pipe, a proportional valve is provided on the air inlet pipe of the burner assembly, and a A con...

AI Technical Summary

Problems solved by technology

Although the patent can automatically turn off the water when it enters the water, it cannot automatically release the water, and the degree of intelligence is not high.

Moreover, since the automatic water valve is set on the water inlet pipe, after the automatic water shut-off valve is closed, other water points cannot use hot water, and the terminal water point on the bathtub must be closed before continuing to use, which is extremely inconvenient to control
