Detailed description of the invention
The utility model mainly comprises tank shell 1, heat-preservation cotton 2, water storehouse 3, the first temperature sensor 4, the first heating rod 5, the first thermal-insulation baffle plate 6, the first check valve 7, inlet damper 8, the second temperature sensor 9, the second heating rod 10, the second thermal-insulation baffle plate 11, the second check valve 12, three-temperature sensor 13, the 3rd heating rod 14, hot-water line 15, controls storehouse 16, control panel 17, cold water pipe 18, mixed water valve 19, warm water tube 20; The circulating-heating process of water: whole water storehouse 3 is separated into three bins by the first thermal-insulation baffle plate 6 and the second thermal-insulation baffle plate 11: left chamber, middle chamber and right ventricle, when after cold water pipe 18 and tap water pipe network connection, first running water flows into left chamber by cold water pipe 18, then chamber in flowing into by the first check valve 7, flows into right ventricle by the second check valve 12; Now control three heating rod work by control panel 17, by water heating, hot water flow in mixed water valve 19 by hot-water line 15, and from the cold water of cold water pipe 18 and after, obtain the warm water of suitable temperature, warm water flows out from warm water tube 20, for use.
Energy Saving Control process: in the time that hot water demand is less, by the control function of control panel 17, only controlling right ventricle's the 3rd heating rod 14 of water storehouse 3 works, in the time that the water in right ventricle is heated to rated temperature, temperature signal is transferred to control panel 17 by three-temperature sensor 13, control panel 17 cuts off the power supply supply of the 3rd heating rod, now can only use the hot water in right ventricle, and due to the insulation effect of the second thermal-insulation baffle plate 11 and the backflow limitation function of the second check valve 12, hot water in right ventricle not can with in indoor cold water there is conduction cooling fast, ensure right ventricle's hot water thermal insulating persistence, when this kind of state uses hot water, cold water is injected left chamber by cold water pipe 18, cold water injects chamber by the first check valve 7, inject right ventricle by the second check valve 12 again, the hot water promoting in right ventricle flows out and uses from hot-water line 15, if when hot water demand is more, in can controlling by control panel 17, the second heating rod 10 of chamber and the 3rd heating rod 14 of right ventricle are worked simultaneously, the water of middle chamber and right ventricle is heated to rated temperature, the second temperature sensor 9 and three-temperature sensor 13 are transferred to temperature signal respectively control panel 17, realize the thermal control that adds to water in these two bins, when this kind of state uses hot water, cold water is injected left chamber by cold water pipe 18, cold water injects chamber by the first check valve 7, cold water runs into stopping of inlet damper 8, in indoor can only flowing downward, avoided cold water in indoor quick convective cooling, make indoor hot water inject right ventricle by the second check valve 12 in the situation that cooling is slower, the hot water promoting in right ventricle flows out and uses from hot-water line 15, if hot water demand is very large, now control panel 17 is controlled three heating rods and is worked simultaneously, the water of three bins is all heated to rated temperature, and rely on respectively the temperature signal of three temperature sensors to realize the thermal control that adds to water in three bins, when this kind of state uses hot water, cold water pipe 18 injects cold water from the lower end of left chamber, a hot water indoor left side is injected into middle chamber by the first check valve 7, in indoor hot water be injected into right ventricle by the second check valve 12, the hot water promoting in right ventricle flows out and uses from hot-water line 15, in this process, cold water is injected into behind left chamber, first the convection heat transfer' heat-transfer by convection of hot and cold water temperature difference maximum carries out instead of carries out in three bins simultaneously in left chamber, therefore middle chamber and right ventricle's cooling are slower, the leaving water temperature cooling of hot-water line 15 is slower, thereby improve overall hot water utilization rate.
