Among each figure, the fine rule indication circuit, thick black line is represented the water route, arrow is represented water (flow) direction.
The specific embodiment
Thinking of the present invention is to replenish the heating of character after water heater main frame delivery port.When the water heater main frame begins water outlet, carry out the heating of complementarity, when the hot water that provides when the water heater main frame reaches predetermined temperature, can stop the heating of complementarity.Heating measure of the present invention can be adopted electrical heating, also can adopt the mode of sneaking into hot water to heat.
An object of the present invention is the water heater main frame is heated to the water between the shower nozzle, so alleged " end " of this paper promptly is meant the back-end location of water heater hot-water outlet pipe, the water inlet of pipeline post heating device promptly is arranged on herein; " final outflow water mouth " is meant at the later final main water route delivery port of pipeline post heating device." end " and " final outflow water mouth " needn't strictness be interpreted as must press close to shower nozzle or shower nozzle itself very much, obviously, even be interpreted as that from nozzle position to last segment distance, for example 10～20cm also is not influence use.
First kind of embodiment is referring to Fig. 1.Arrow among the figure is represented water (flow) direction.Water heater pipeline post heating device of the present invention comprises control module 4 and heating unit 2, and control module 4 is connected with heating unit 2.Heating unit 2 is an electric heater, and control module 4 promptly is the switch of heating unit 2.The water temperature detecting unit 1 that is connected with control module 4 in addition.Described water temperature detecting unit 1 is arranged at the water inlet of pipeline post heating device, owing to pipeline post heating device is arranged at after the delivery port of water heater main frame, so the water inlet of pipeline post heating device also is positioned at after the delivery port of water heater main frame.The temperature of the current that described water temperature detecting unit 1 detection water heater main frame provides, if temperature is low excessively, control module 4 starts heating units 2; After current that the water heater main frame provides reached sufficiently high temperature, the heating unit 2 of pipeline post heating device stopped heating, the hot water that the direct heat outputting hydrophone of water pipe main frame provides.
Heating unit is recommended to use electrical heating, because electroheat technology has belonged to mature technology, so this paper repeats no more its concrete structure.
The water temperature detecting unit can use bimetal leaf.When the present invention is in running order, if the water inlet water temperature of pipeline post heating device is low excessively, then open the switch of electric heater, current are heated; If pipeline post heating device water inlet water temperature is enough high, then close the power switch of electric heater.Present embodiment also can solve gas heater because air pressure change causes sometimes hot and sometimes cold problem.
Second kind of embodiment is referring to Fig. 2.The place also is provided with temperature detector 3 at the final outflow water mouth, its effect is, can regulate the power of electric heater according to the water temperature at pipeline post heating device delivery port place, in the process that the current temperature that the water heater main frame provides rises gradually, reduce the power of electric heater gradually, make that the current water temperature that finally provides is constant substantially.
The present invention can also increase discharge or hydraulic pressure detection module, and it is connected with heating unit, and the post heating device of blinding off a line when flow or hydraulic pressure are low excessively to avoid and scalds or " dry combustion method " phenomenon.
The third embodiment: see Fig. 3.Water route after the pipeline post heating device water inlet is divided into two-way, the water mixing valve 6 of leading up to connects the final outflow water mouth, one the tunnel connects heating unit 2, the pipeline post heating device water inlet is provided with pipeline post heating device water inlet water temperature detecting unit 1, the outlet pipe of heating unit 2 is by electric control valve 5 water receiving mixing valves 6, and control module 4 is connected with electric control valve 5.
The present invention also provides the water heater that has aforementioned pipeline post heating device, as Fig. 4.A is a water heater among the figure, and B is a pipeline post heating device.Pipeline post heating device is arranged at the back level of water heater main frame delivery port.
The invention provides a kind of method for heating domestic water, comprise the steps:
1) water heater host-initiated and water supply start;
2) carry out supplementary heating by near pipeline post heating device current to the water heater outlet final outflow water mouth.
Can also comprise step 3): when the current of water heater outlet reach predetermined temperature, stop supplementary heating.
Consider that gas heater opens along with hot water effluent's pipeline and start, that is, open hot water effluent's valve, gas heater promptly starts, so abovementioned steps 1), step 2) time sequencing need not strict the differentiation.
As an improvement, described step 2) be: the water temperature of signal piping post heating device water inlet does not then start supplementary heating if reach predetermined temperature.
More specifically, be divided into two kinds of embodiment of storage-type supplementary heating and directly-heated type supplementary heating, specific as follows:
Storage-type supplementary heating embodiment: referring to Fig. 3.
1) storage-type pipeline post heating device 4 is full of water in advance, is heated to the design temperature that is relatively higher than serviceability temperature and enters the insulation pattern;
2) electrically-controlled valve 5 is opened, and the heat storage type pipeline post heating device provides high-temperature-hot-water immediately, through water mixing valve 6 and the not heated cold water mix of coming to water heater pipeline, in time exports the hot water of serviceability temperature.Simultaneously, because of the effect of current, start water heater and begin the interior cold water of heating pipe line.
3) arrive pipeline post heating device when the hot water that heated by water heater, and water temperature is when reaching serviceability temperature, attemperating unit is controlled electrically-controlled valve 5 immediately and is closed out water passage.
The embodiment of directly-heated type supplementary heating:
1) the directly-heated type pipeline post heating device enters "on" position, configures leaving water temperature and standby.
3) hot-water valve is opened, and the directly-heated type pipeline post heating device that is started by current provides high-temperature-hot-water immediately, through water mixing valve and the not heated cold water mix of coming to water heater pipeline, in time exports the hot water of serviceability temperature.Simultaneously, because of the effect of current, start water heater and begin the interior cold water of heating pipe line.
4) arrive pipeline post heating device when the hot water that heated by water heater, and water temperature is when reaching serviceability temperature, directly-heated type pipeline post heating device entry temperature control equipment is controlled heater circuit immediately and is cut off the electricity supply.Allow water heater come water to pass through mixing valve and directly supply use.
Specification of the present invention has been described in detail the principle of the present invention and the course of work, and those of ordinary skill fully can be according to the enforcement with no difficulty of this specification, and wherein concrete circuit or water route structure are all prior art, no longer launches explanation.
