Water mixing device for automatic constant-temperature water mixing valve

Abstract

The invention discloses a water mixing device for an automatic constant-temperature water mixing valve. The water mixing device comprises a cold water inlet, a hot water inlet, a mixing chamber, a mixed water outlet and a water current vortex generator, wherein cold water and hot water flow into the water current vortex generator from the cold water inlet and the hot water outlet respectively to generate spiral movement and generate vortex movement in the mixing chamber, so that the cold water and the hot water are uniformly mixed quickly. A vortex water mixer for the automatic constant-temperature water mixing valve, disclosed by the invention, has the advantages of small size, low cost and simple structure, and ensures that a temperature sensor of an automatic constant-temperature water mixing valve correctly reflects the temperature of uniformly-mixed cold water and hot water. By adopting the automatic constant-temperature water mixing valve adopting the water mixing device, the phenomenon of variable temperature of drained water is overcome.

Description

Technical field [0001] The invention relates to an automatic constant temperature water outlet device, in particular to a water mixing device for an automatic constant temperature water mixing valve. Background technique [0002] At present, automatic thermostatic mixing valves (commonly known as mechanical automatic thermostatic valves) using wax or shape memory alloy springs as thermal actuators have been on the market for many years. However, due to the limitations of this automatic thermostatic mixing valve, it has not been popularized on a large scale. Its main disadvantage is that the temperature adjustment operation is the same as that of ordinary mixing valves. Fixed temperature; and, the so-called constant temperature, but when the temperature (or pressure) of the incoming cold water (or hot water) changes within a small range, the corresponding change in the temperature of the output mixed water is relatively small. And when the temperature (especially pressure) o...

However, due to the limitations of this automatic thermostatic mixing valve, it has not been popularized on a large scale. Its main disadvantage is that the temperature adjustment operation is the same as that of ordinary mixing valves. Fixed temperature; and, the so-called constant temperature, but when the temperature (or pressure) of the incoming cold water (or hot water) changes within a small range, the corresponding change in the temperature of the output mixed water is relatively small

[0007] In fact, the mechanical automatic thermostatic valve also has this problem, but the temperature sensing area of ​​its thermal actuator is much larger than that of the electronic temperature sensor, and the situation is not as serious as that of the electronic temperature sensor.
