Detailed description of the invention
Below in conjunction with accompanying drawing and specific embodiment, the present invention is further illustrated, but protection scope of the present invention is not limited to this.
As shown in Figure 1, a kind of novel water-saving temp control device, including water heater 1, water feeding of heater pipeline 13, water outlet of water heater pipeline 5 and cold water pipes 9, the import of described water heater 1 connects water feeding of heater pipeline 13, and water feeding of heater pipeline 13 is provided with the second valve 14;The outlet of described water heater 1 connects water outlet of water heater pipeline 5, which is provided with the first valve 4;The outlet of described water outlet of water heater pipeline 5 connects cold water pipes 9 and hot water pipeline 12;The outlet water feeding of heater pipeline 13 of described cold water pipes 9;Described water outlet of water heater pipeline 5 is provided with the normal open switch 2 of temperature measurement and the normally closed switch 3 with temperature measurement;The model of the normal open switch 2 with temperature measurement chooses the knob temperature detect switch (TDS) of 220V, 36A (30~110 DEG C);The model of the normally closed switch 3 with temperature measurement chooses the knob temperature detect switch (TDS) of 220V, 36A (30~110 DEG C), and market is all on sale.Described water outlet of water heater pipeline 5 is connected with hot water pipeline 12 by the first electrically operated valve 11, and described water outlet of water heater pipeline 5 is connected with cold water pipes 9 by the second electrically operated valve 8;Described normal open switch 2 downlink connection the first electrically operated valve 11 with temperature measurement;The described normally closed switch 3 with temperature measurement connects the second electrically operated valve 8;Namely the normal open switch 2 with temperature measurement controls the first electrically operated valve 11 aperture, and the normally closed switch 3 with temperature measurement controls the second electrically operated valve 8 aperture.
It is provided with check valve 10 so that the water in cold water pipes 9 can enter in water feeding of heater pipeline 13, and the water of water feeding of heater pipeline 13 does not flow into cold water pipeline 9 between described cold water pipes 9 and water feeding of heater pipeline 13.
Lateral 15 also it is communicated with in the middle part of hot water pipeline 12;Described lateral 15 and hot water pipeline 12 junction are provided with movable baffle plate 7;Described lateral 15 connects electric heat constant temp. water tank 6;The caliber of described lateral 15 is less than the caliber of hot water pipeline 12;Between described lateral 15 and hot water pipeline 12, angulation is 30-60 DEG C;Described water heater 1 and electric heat constant temp. water tank 6 are same on-off control, and when starting water heater 1, electric heat constant temp. water tank 6 also begins to work.The outlet of described electric heat constant temp. water tank 6 is provided with the 3rd valve 16.
Work process:
Cold water is entered in water heater 1 by water feeding of heater pipeline 13 and heats, and opens the first valve 4, and water enters in water outlet of water heater pipeline 5;Normal open switch 2 with temperature measurement and the normally closed switch with temperature measurement 3 monitor water temperature in real time;When water temperature is lower than preset value T, the normally closed switch 3 with temperature measurement is opened, and the second electrically operated valve 8 is opened, and now, the normal open switch 2 with temperature measurement is opened, the first electrically operated valve Guan Bi;Entered in water feeding of heater pipeline 13 by cold water pipes 9 through check valve 10 not up to the water of temperature, it is achieved early stage discards cold water reuse;When water temperature exceedes preset value T, the normally closed switch 3 with temperature measurement is opened, and the second electrically operated valve 8 is closed, and cold water pipeline 9 is closed;Normal open switch 2 with temperature measurement closes, and powers to the first electrically operated valve 11 so that the first electrically operated valve 11 is opened, and hot water is flowed out by hot water pipeline 12;Meanwhile, after water heater 1 is activated, the switch in electric heat constant temp. water tank 6 also starts simultaneously, and the cold water in electric heat constant temp. water tank 6 is rapidly heated to preset temperature T, and in time having fluid to flow through in hot water pipeline 12, movable baffle plate 7 remains off;When passing through without fluid in hot water pipeline 12, opening the 3rd valve 16, movable baffle plate 7 is opened under fluid pressure effect, and the hot water in electric heat constant temp. water tank 6 can pass through lateral 15 and flow in hot water pipeline 12;The uninterrupted supply of hot water is realized with this.
Described embodiment be the present invention preferred embodiment; but the present invention is not limited to above-mentioned embodiment; when without departing substantially from the flesh and blood of the present invention, those skilled in the art can make any conspicuously improved, replace or modification belongs to protection scope of the present invention.
