Abstract
An electric constant temperature water heater provided with cold-and-hot double water inlet tubes comprises an outer shell (1), ventilation holes (2), a water level sensor (3), an upper water inlet valve (4), a lower water inlet valve (5), a water outlet valve (6), a control panel (7), a main controller (8), an electric heating device (9), a water level regulating valve (10) and the like; and electromagnetic valves, temperature sensors and water flow sensors are installed on the upper water inlet valve (4) and the lower water inlet valve (5), an electromagnetic valve is installed on the water level regulating valve (10), a temperature sensor and a water flow sensor are installed on the water outlet valve (6), water temperature required by a user can be set, regulated and memorized on the control panel, and outlet water temperature is displayed on the control panel. The electric constant temperature water heater provided with the cold-and-hot double water inlet tubes has the advantages that when inlet water temperature is lower than the set water temperature, inlet water is automatically heated; and when the inlet water temperature is higher than the set water temperature, a tap water valve is automatically opened, the water temperature is regulated to be low, whether the inlet water temperature is high or low, the outlet water temperature is steady, the electric constant temperature water heater provided with the cold-and-hot double water inlet tubes is particularly suitable for being connected with a solar water heater, and constant temperature of outlet water of the solar water heater is achieved.
Description
Technical field
The utility model relates to household appliance technical field, is a kind of electric constant-temp water heater with cold and hot double water inlet pipes specifically.
Background technology
Water heater mainly contains three kinds in the market, be solar water heater, electric heater and gas heater, the water heater that can realize constant temperature has only electric heater and gas heater, but these two kinds of constant-temperature hot water devices all have only a water inlet pipe, an outlet pipe, can only be used for heating to cold water, reckon without the situation of inflow temperature height (as solar water) needs cooling sometimes.Though now can manual adjustment by mixing water valve, owing to the pressure of cold water and hot water is different, manual adjustment is more difficult when being difficult to be adjusted to suitable temperature, particularly children and old man and using.
Summary of the invention
The utility model provides a kind of electric constant-temp water heater with cold and hot double water inlet pipes, if when inflow temperature is lower than design temperature, can heat up; If when inflow temperature surpasses the leaving water temperature of setting, can lower the temperature.
The technical solution adopted in the utility model:
1, a kind of electric constant-temp water heater with cold and hot double water inlet pipes comprises compositions such as shell, passage, level sensor, last water intaking valve, following water intaking valve, outlet valve, water level adjustment valve, control panel, electric heater unit, master controller;
2, described going up on water intaking valve, the following water intaking valve is equipped with electromagnetic valve, temperature sensor, water flow sensor, and electromagnetic valve, temperature sensor, water flow sensor are connected with master controller, and electromagnetic valve is subjected to main controller controls;
3, described water level is adjusted on the valve electromagnetic valve is installed, and is subjected to main controller controls;
4, on the described outlet valve temperature sensor, water flow sensor are installed, temperature sensor, water flow sensor are connected with master controller;
5, described control panel links to each other with master controller, can set, adjust, remember the water temperature that the user needs on the panel, shows the water outlet water temperature.
6, described electric heater unit is subjected to main controller controls.
Advantage of the present utility model:
A kind of electric constant-temp water heater with cold and hot double water inlet pipes that the utility model provides, when inflow temperature is lower than set water temperature, heating automatically; When inflow temperature is higher than set water temperature, open running water valve automatically and turn down water temperature, inflow temperature height no matter, leaving water temperature is stable, is particularly suitable for being connected with solar water heater, realizes the solar water heater constant-temperature effluent.
Description of drawings;
Fig. 1 is the utility model structural representation
The specific embodiment:
Following embodiment is non-limiting embodiment of the present invention.
As Fig. 1, the 1st, constant-temperature hot water device shell, the 2nd, passage, when the user after control panel 7 is set a certain temperature, this design temperature signal sends master controller 8 to, master controller 8 usefulness level sensors 3 are measured the water level of the interior water of water heaters.If water level is low excessively, then open inlet valve 4 moisturizings, water level is closed water intaking valve 4 after reaching normal value; Adjust valve 10 drainings as the too high water level of then opening of water level, water level is closed water level adjustment valve 10 after reaching normal value.If water level is in range of normal value, master controller 8 usefulness are installed in the temperature sensor measurement water water temperature on the outlet valve and dynamically show water temperature.Be lower than design temperature as water temperature and then start heater 9, when water temperature reaches design temperature, stop heating; Being higher than set water temperature as water temperature, then to open down inlet valve be running water valve 5, turns down water temperature, closes down inlet valve 5 when water temperature reaches design temperature.
After the user opened flowing water Valve 6, the water flow signal sent master controller 8 to, and master controller open to be gone up inlet valve 4, on intake water temperature signal and flow signal send master controller 8 to.Master controller 8 goes out whether to open electric heater unit 9 or following inlet valve 5 according to design temperature signal, last inflow temperature signal, enterprising water flow signal, water flow calculated signals, and determines upper and lower flow of inlet water size or electrical heating payload.When water flow changed, master controller 8 can recomputate and adjust upper and lower inflow and electrical heating load rapidly, keeps water temperature stability.Close flowing water Valve 6, the water flow signal terminating, master controller 8 cuts out all switch valves.
