Description

Automatic controller for temperature

The present invention relates to a kind of automatic controller for temperature, particularly about controlling hot water or cold water's water temperature control device.

The dispense flow rate that habitual control hot water or cold water's open and close and hot water or cold water mix roughly is divided into following three kinds of modes:

First kind of mode makes hot water or cold water's the water outlet water delivering orifice of flowing through jointly respectively, controlling hot water or cold water's water flow respectively, thus the water temperature of control water delivering orifice.

The second way, mode for rocking bar, the fulcrum of rocking bar is set on the ratchet knob of mixing valve for cold and hot water, the ratchet knob of operation valve has the three-way pipe effect, hot water or cold water's water outlet is connected to one of three-way pipe respectively, three-way pipe is and blends the mouth of a river, the switch degree size of ratchet knob may command hot water or cold water siphunculus, the rotational angle of mat ratchet knob, control hot water or cold water's switch and water flow respectively, with the water temperature of control water delivering orifice water outlet, that is, control the water temperature of water delivering orifice with the angle that swings of rocking bar.

The third mode is the rocking bar mode still, and principle is the same, but the rocking bar cording has upper and lower and left and right pendulum angle, and the upper and lower and left and right pendulum angle of mat rocking bar is with the water temperature of control water delivering orifice.

More than three kinds of modes, all by the water temperature of manual mode control water delivering orifice, still, these control modes exist following shortcoming 1. can only control the water temperature of water delivering orifice with manual mode, can not control automatically.2. do not have temperature and show, be difficult to learn real water temperature and whether adjust the temperature of hot water for institute's desire.3. can not remote control, therefore extremely difficultly reach real thermostatic control.

For this reason, it is easy and convenient to the invention provides a kind of use, the automatic controller for temperature of control automatically effectively, displays temperature, remote control water temperature.

Fundamental purpose of the present invention is to provide a kind of really device of automatic control water temperature.
