Abstract
An instant water heater comprises an inlet pipe, an outlet pipe, a heater, a heating box and a tee joint for controlling flow direction of water path from the outlet pipe to the heater and the heating box. After heat source in the heating box flows out of a first water outlet and exchanges heat with water flowing out of the inlet pipe, required hot water is generated. Dissolved heat release material is disposed in the heating box. A reverse osmosis membrane is arranged at a second water outlet of the heating box. After heating, the hot water is filtered by the reverse osmosis and purified water is obtained; and the dissolved heat release material dissolves and remains in the heating box for next use, and the filtered purified water backflow to the preheat box to form the original hot water. The instant water heater has the advantages that the structure is simple and compact; after dissolved in the water, the dissolved heat release material releases a great amount of heat instantly, the required hot water is obtained from the outlet pipe, and accordingly instant heating is effective, using cost is low and energy saving is evidently effective; and the purified water can be cyclic utilized, so that water resources are saved and heat utilization rate is increased.

Fig. 2 is the structural representation of the embodiment of the present invention at the end of heat supply and heating.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the present invention is described in further detail.
As depicted in figs. 1 and 2, the immediately heating water heater in the present embodiment mainly comprises the assemblies such as water inlet pipe 1, outlet pipe 2, heat exchanger 3, heating cabinet 4, threeway 5, exothermic dissolution material 6, reverse osmosis membrane 7, first circulating pump 8, preheating cabinet 9, blower fan 10 and the second circulating pump 11.Wherein, heater and attemperating unit is equipped with in preheating cabinet 9 and heating cabinet 4, in the present embodiment, the first infrared heater 12 is provided with in preheating cabinet 9, the second infrared heater 13 is provided with in heating cabinet 4, attemperating unit in preheating cabinet 9 can realize temperature and control to the preheating water in preheating cabinet, automatically the power supply of the first infrared heater is disconnected when preheating water exceedes its design temperature, heating stops, thus in preheating cabinet 9, generating the preheating water of constant temperature, the temperature of general constant temperature preheating water can be set as 25 degree.Similarly, attemperating unit in heating cabinet 4 can realize temperature and control to the heat source water in heating cabinet, automatically the power supply of the second infrared heater is disconnected when heat source water exceedes its design temperature, heating stops, thus in heating cabinet 4, generating the heat source water of constant temperature, the temperature of general constant temperature heat source water can be set as 70-90 degree.
In preheating cabinet 9, there is original hot water, enters preheating cabinet 9 from the water of water inlet pipe 1 inflow and be mixed into constant temperature preheating water through the first infrared heater 12 heating with original hot water.Constant temperature preheating water flows out rear inflow threeway 5 from preheating cabinet 9, and constant temperature preheating water is controlled to the water route flow direction of heating cabinet 4 and outlet pipe by threeway.
In the process of constant temperature preheating water injection heating case 4, first delivery port 41 of heating cabinet 4 and the second delivery port 42 are all in closed condition, the water-soluble rear rapid heat release of exothermic dissolution material 6 in heating cabinet 4 makes the water temperature in heating cabinet 4 raise, and becomes heat source water after the second infrared heater 13 in heating cabinet 4 heats.After constant temperature preheating water fills heating cabinet 4, under threeway 5 controls, constant temperature preheating water stops toward heating cabinet 4 water filling and changes inflow heat exchanger 3 into, now, first delivery port 41 of heating cabinet 4 is opened and the second delivery port 42 continues to close, heat source water flows out rear inflow heat exchanger 3 from the first delivery port 41 and carries out heat exchange with the constant temperature preheating water of inflow heat exchanger 3, and constant temperature preheating water flows out from outlet pipe 2 and becomes required hot water after heat exchange, and hot water temperature can reach 35-55 degree.Be back in heating cabinet 4 by the second circulating pump 11 after the heat source water of inflow heat exchanger 3 and air generation exchange heat and again heat, and act on through blower fan 10 while heat exchange and generate the heating installation needed for bathroom, the temperature of heating installation can reach 30-50 degree.After heat supply and heating terminate, under threeway 5 controls, constant temperature preheating water had both stopped toward heating cabinet 4 water filling, stop inflow heat exchanger 3 again, now, first delivery port 41 of heating cabinet 4 is closed and the second delivery port 42 is opened, heat source water in heating cabinet 4 obtains pure water under the effect of the first circulating pump 8 after reverse osmosis membrane 7 permeation filtration, pure water flows in preheating cabinet 9 and forms original hot water, realization recycles, meanwhile, exothermic dissolution material 6 is stayed in heating cabinet 4 after separating out, and again utilizes when next heat supply heating.
In the present embodiment, exothermic dissolution material 6 adopts the mixture of aluminum sulfate or magnesium sulfate or calcium nitrate or calcium chloride or any two materials at least above-mentioned, the thermal effect of this several exothermic dissolution material should be able to ensure that the heat source water in heating cabinet 4 reached design temperature in 30 seconds, realizes instant heating.Compared with existing immediately heating water heater, not only use cost is cheap to adopt exothermic dissolution material to obtain heat source water, and energy-saving effect is obvious, and namely fuel factor is better.
In addition, in order to obtain good heat insulating effect, in the present embodiment, the shell material of heating cabinet 4 and preheating cabinet 9 is pottery or atactic copolymerized polypropene.In order to improve intelligence degree further, this immediately heating water heater integrated control device (not shown), this integrated control device can set heat source water temperature, from the hot water temperature of outlet pipe 2 outflow and the heater temperature from blower fan 10 blowout, and, under the control of this integrated control device, actual hot water temperature and the error between heater temperature and respective design temperature are all no more than 1 degree.
The foregoing is only the preferred embodiment of the present invention; should be understood that; for those of ordinary skills; do not departing under principle prerequisite of the present invention; multiple remodeling or improvement can be carried out to the present invention; such as exothermic dissolution material is not limited to several materials that the present embodiment provides; it can also be the material that other specific heat capacities are higher; the shell material of such as heating cabinet and preheating cabinet is except the material that employing the present embodiment provides again; can also adopt other heat preserving and insulating materials etc., these are all regarded as within protection scope of the present invention.
