Intelligent bathtub and water filling control method thereof

Abstract

The invention discloses an intelligent bathtub and a water filling control method thereof. The intelligent bathtub comprises a bathtub body, a water level gauge for measuring the water level of the bathtub, a water mixing valve, an electromagnetic valve, a draining valve, a first thermometer, a second thermometer, an input unit and a controller. The method includes: in a water mixing valve temperature regulating stage, opening the draining valve, using the second thermometer to measure draining water temperature, controlling the temperature of mixed water according to the draining water temperature, and closing the draining valve and starting water filling after the draining water temperature reaches set temperature; in the water filling stage, using the first temperature meter to measurethe temperature of the mixed water, allowing the controller to continuously regulate the water mixing valve according to the temperature difference between the temperature of the mixed water and the set water temperature to allow the temperature of the mixed water to be kept at the set water temperature and prevent the temperature lowering, caused by the continuous hot water output, of the mixed water. By the water filling control method, the fact that the actual temperature of the mixed water in the bathtub is the set water temperature can be guaranteed, and the control precision of the actual temperature of the mixed water of the intelligent bathtub is increased.

Description

technical field [0001] The invention belongs to the technical field of intelligent sanitary ware, and in particular relates to an intelligent bathtub and a water filling control method thereof. Background technique [0002] With the development of science and technology, smart home devices have rapidly spread to thousands of households, greatly improving people's living environment and enhancing people's life experience. As a kind of household equipment for bathing and bathing, bathtub can help people relieve fatigue, relieve nerves and relax body and mind, and enhance the warmth and comfort of family life. With the development of bathroom technology, existing smart bathtubs can assist people in operations such as water filling and drainage, and also have the function of assisting in adjusting the water filling temperature of the bathtub, which is convenient for people to use. The existing intelligent bathtub mixed water temperature adjustment method is all based on the mix...

AI Technical Summary

Problems solved by technology

Since the temperature adjustment stage coincides with the water filling stage of the bathtub, the temperature of the mixed water filled into the bathtub during the temperature adjustment stage cannot be determined, and the bathtub is not preheated before filling, resulting in a large gap between the actual mixed water temperature in the bathtub and the set water temperature. Therefore, the existing smart bathtubs cannot accurately control the actual mixed water temperature in the bathtub, which reduces the experience and comfort of people using the smart bathtub to a certain extent.
