A constant temperature bathing system

Abstract

The invention discloses a constant-temperature bathing system which comprises an electric heating water tank, a thermostatic controller, a sensing unit, a water temperature regulating unit, a manual control valve and a bathing sprayer. A control panel is mounted on the electric heating water tank. The control panel comprises a heating switch, a hot water temperature display unit, an outlet water temperature display unit and a temperature setting unit. The sensing unit comprises a room temperature sensor, a hot water temperature sensor, an outlet water temperature sensor, a water flow sensor and an infrared sensor. The water temperature regulating unit comprises a drive motor and a mixing valve. The constant-temperature bathing system has the advantages that information sampling of the sensing unit and the output control of the water temperature regulating unit are utilized to keep outlet water temperature constant, inconvenience caused by manual valve regulation during bathing is avoided, the sprayer has a spraying mode and a showering mode, good heat transfer effect is achieved, system energy utilization rate is increased greatly, and a user can simply setting outlet water temperature by pressing a button according to the temperature information of the display unit.

Description

technical field [0001] The invention belongs to the technical field of constant temperature control, in particular to a constant temperature bathing system. Background technique [0002] At present, most households use electric water heaters or solar water heaters for bathing. They use electric energy and solar energy to heat and keep the water stored in the box respectively. Since most of the cold and hot water pipes in the family use a water supply system, when other users use cold water or hot water, the water pressure in the cold water or hot water pipes is often reduced, which in turn leads to the situation that the water is too cold or too hot during the bathing process. . In addition, the general electric water heater has a small water tank capacity, and the stored hot water often cannot meet the needs of bathing. When the user takes a bath, the water heater must always heat the cold water and add it to the water tank. However, the speed of the user's water is oft...

Problems solved by technology

However, the temperature curve corresponding to the elongation or contraction of the thermal element is often not very symmetrical, and even the temperature curve on the elongation or contraction side does not have good linear characteristics, so it is difficult to achieve precise control of the outlet water temperature adjustment

In addition, due to their own sensitivity limitations, most of the thermosensitive elements do not have the ability to respond quickly when there is a small fluctuation in the outlet water temperature, which will easily lead to a situation where the adjustment time is too long when the outlet water temperature undergoes a large change.
