Abstract
The utility model belongs to electric water heater equipment and in particular relates to a constant temperature device for an electric water heater. The constant temperature device comprises a computer control system, a heating inner container, a three-way cold water pipe (1) and a three-way hot water pipe (2), wherein the three-way cold water pipe and the three-way hot water pipe are communicated through a transverse pipe (3). A cold water temperature sensing probe (6) is internally arranged close to the connection position of the three-way hot water pipe and the transverse pipe, an outlet water temperature sensing probe (7) is internally arranged close to the three-way position of the three-way hot water pipe, and a hot water temperature sensing probe (8) is arranged close to the connection position of the three-way hot water pipe and the heating inner container. The water heater of the technical scheme has the advantages of being constant in temperature, intelligent, convenient, safe to use for the old and the young and capable of avoiding scald, thereby filling the technical gas that water-storage quickly-heating water heater with computer constant temperature doesn't exist.
Description
Technical field
The utility model belongs to electric water heater equipment, specifically is a kind of electric water heater constant temperature device.
Background technique
Electric water heater of the prior art is to utilize the inner hot and cold water valve of the manual left and right adjusting of manually mixed water valve to regulate, and there is defective in this manually mixing in the water valve using process:
1, a lot of water of waste in adjustment process;
2, be prone to smelt during manual tune and hinder skin;
3, the temperature of water outlet also and then changes during the hydraulic pressure size variation, and is sometimes hot and sometimes cold;
4, inconvenient during user installation;
5, in addition, adopt and mix water valve, cost is higher.
The model utility content
To the above, the utility model aims to provide a kind of user of need not and manually sets, and just can realize the electric water heater constant temperature device of constant-temperature effluent.
For realizing above-mentioned purpose; A kind of electric water heater constant temperature device of the utility model; Comprise control system, heating inner bag, threeway cold water pipe and threeway hot-water line, said threeway cold water pipe and threeway hot-water line are communicated with through transverse tube, near the built-in cold water temperature inductance probe of said threeway hot-water line and transverse tube joint; Export built-in water outlet temperature inductance probe near said threeway hot-water line threeway place flow of hot water, the hot water temperature inductance probe is set near said threeway hot-water line and heating inner bag joint.
Said threeway cold water pipe and threeway place of threeway hot-water line be built-in first stepper motor and second stepper motor respectively.
Said inner bag one end connects the hot-water outlet who advances cold water outlet, the other end connection threeway hot-water line of threeway cold water pipe.
Adopt the beneficial effect of this programme: the electric water heater constant temperature device of the utility model; Because said threeway cold water pipe and threeway hot-water line are communicated with through transverse tube; Near the built-in cold water temperature inductance probe of said threeway hot-water line and transverse tube joint; Export built-in water outlet temperature inductance probe near said threeway hot-water line threeway place flow of hot water, the hot water temperature inductance probe is set, when the hot water temperature inductance probe detects temperature and is higher than preset temperature near said threeway hot-water line and heating inner bag joint; Automatic control system is sent instruction and is started first stepper motor through transverse tube injection cold water, reduces temperature; When the cold water temperature inductance probe detected temperature and is less than or equal to preset temperature, automatic control system was sent instruction and is closed first stepper motor; When the water outlet temperature inductance probe detected temperature and is below or above preset temperature, automatic control system sent that instruction starts first stepper motor and second stepper motor injects hot water or cold water.
To sum up can know, adopt the electric water heater of present technique scheme to have temperature constant, beneficial effect easy to use.

Embodiment
As shown in Figure 1; A kind of electric water heater constant temperature device of the utility model; Comprise control system, heating inner bag, threeway cold water pipe 1 and threeway hot-water line 2; Said threeway cold water pipe and threeway hot-water line are communicated with through transverse tube 3, and transverse tube fastens through interface 13 sealings, near said threeway hot-water line 2 and the built-in cold water temperature inductance probe 6 in transverse tube 3 joints; Export built-in water outlet temperature inductance probe 7 near said threeway hot-water line 2 threeway place flow of hot water, hot water temperature inductance probe 8 is set near said threeway hot-water line 2 and heating inner bag joint; Said threeway cold water pipe 1 and threeway hot-water line 2 threeways place built-in first stepper motor 4 of difference and second stepper motor 5; Said inner bag one end connects the hot-water outlet 10 who advances cold water outlet 9, the other end connection threeway hot-water line 2 of threeway cold water pipe 1, and the other end 12 of threeway cold water pipe 1 connects water taps, and the other end 11 of threeway hot-water line 2 connects bathings and uses gondola water faucet.
Working procedure is described: when hot water temperature inductance probe 8 detected temperature and is higher than preset temperature, automatic control system was sent instruction and is started first stepper motor 4 and inject cold water through transverse tube 3, reduces temperature; When cold water temperature inductance probe 6 detected temperature and is less than or equal to preset temperature, automatic control system was sent instruction and is closed first stepper motor 4; When water outlet temperature inductance probe 7 detected temperature and is below or above preset temperature, automatic control system was sent instruction and is started first stepper motor 4 and second stepper motor, 5 injection hot water or cold water.
Above embodiment describes the preferred implementation of the utility model; Be not that scope to the utility model limits; Under the prerequisite that does not break away from the utility model design spirit; Various distortion and improvement that the common engineers and technicians in related domain make the technological scheme of the utility model all should fall in the protection domain that claims of the utility model confirm.
