To control unit, control unit control pumping unit is opened, with accelerate the flow velocity of water in liquid hot duct or floor heating pipeline from
And promote indoor temperature.
4. liquid line spill and leakage automatic detection and control device according to claim 1, it is characterised in that probe unit can
Light sensation probe or microwave sonar inductive probe are replaced with, light sensation probe and microwave sonar inductive probe are according to the property for being detected body
It uses or is used alone simultaneously, light sensation probe is optical sensor, and microwave sonar inductive probe is sonar sensor, is also applied to gas
In the leak detection of body pipeline.
5. liquid line spill and leakage automatic detection and control device according to claim 1, it is characterised in that pass through infinite network
Technology is connectable in intelligent domestic system, by network intelligence terminal control, is realized long-range on-off line operation, is avoided because of liquid
The generation of economic loss and personal injury caused by pipeline spill and leakage.
