Be described further with regard to technological scheme of the present invention below in conjunction with drawings and the specific embodiments.Should be appreciated that specific embodiment described herein only in order to explain the present invention, is not intended to limit the present invention.
The present invention proposes a kind of water temperature automatic regulating device.
With reference to Fig. 1, Fig. 1 is the structural representation of water temperature automatic regulating device of the present invention.
In the present embodiment, a kind of water temperature automatic regulating device, comprise water inlet of hot water 10, cold water inlet 20, water outlet 30, water inlet of hot water water valve 41, cold water inlet water valve 42 and water outlet water valve 43, this water temperature automatic regulating device also comprises the first motor 51 of being located at the water inlet of hot water place and being used for control water inlet of hot water water valve 41 switches; Be located at the cold water inlet place and be used for the second motor 52 of control cold water inlet water valve 42 switches; Be located at water outlet and be used for the solenoid valve 53 of control water outlet water valve 43 switches; Be connected respectively and be used for adjusting the controller 60 of mouth of a river temperature with solenoid valve with the first motor, the second motor.Particularly, water outlet also can be connected with gondola water faucet and can be used on the shower set, and being used for derives the mixed water of hot water or cold water.
After in controller, inputting a target temperature, control chip is according to temperature, flow and the target temperature of hot water in temperature, flow and the water inlet of hot water of cold water in the cold water inlet in the controller, calculate cold water inlet and flow out the flow of cold water and the flow that water inlet of hot water flows out hot water, then by regulating the positive and negative size of regulating respectively the water inlet of hot water valve switch, the size of cold water inlet valve switch of transferring of the first motor, the second motor, reach the purpose of regulating cold water inlet flow and water inlet of hot water flow.
Wherein, mix to adjust the temperature at the mouth of a river with cold water and hot water and utilized principle of conservation of energy, after namely hot and cold water mixed, the heat that cold water partially absorbs equaled hot water part liberated heat.
Setting the water outlet water temperature is t, cold water temperature is t1 in the cold water inlet, the hot water temperature is t0 in the water inlet of hot water, cold water flow M in the cold water inlet, hot water flow is m in the water inlet of hot water, and C is that specific heat of water holds, and Q inhales the heat that (cold water) be cold water absorption when partially mixed, Q is put (hot water) and is hot water liberated heat when partially mixed, and then they satisfy following relation:
