Abstract
The utility model relates to a quick heating type electric water heater, which is characterized in that an electric heating body component is composed of a heating element with constant temperature namely a PTC thermistor, an electrode plate and an insulation layer with favorable thermal conductivity at the outer layer of the electrode plate, the outer surface of the insulation layer is provided with water slots for transferring heat (or densely arranged water pipes for transferring heat), and after power is switched on, the heat of the PTC heating element can be continually transferred to the water slots for transferring heat for heating water current in the water slots via the electrode plate and the insulation layer. Due to the adoption of the PTC thermistor as the heating element with constant temperature, the utility model can be used for heating water quickly, and water temperature can be automatically regulated via the size of water flowrate at a water outlet.
Description
The utility model relates to a kind of water heater technology that is used for daily life, particularly a kind of Instant heating type electric heater.
The useful combustion type of existing water heater, also having is the electric heater that heats with heating wire.Use the gas water heater of piped gas (or liquefied petroleum gas etc.), heat time heating time is short, the heat supply water time is long, though Instant heating type effect is arranged, and the scope of application is restricted, as there are not the place of gas supply or the unsettled place of hydraulic pressure not to use, also there is the use cost height in addition, the chance that breaks down is many, and gas poisoning easily takes place in the closed environment poor stability especially in the winter time.Use relatively health of electric heater, but owing to adopt the heating wire heating, power consumption is big, generally more than 1.5 kilowatts, and preheating time is long, need half an hour approximately, have also that volume is big, the problem of Heavy Weight (because will to the water preheat of the water storage tank of certain volume), also have the shortcoming that fault is many, want power consumption insulation, resistance wire easily to blow at ordinary times in addition.
The purpose of this utility model is to design a kind of Instant heating type electric heater, makes it to have that volume is little, in light weight, efficient is high, heating is fast, safety easy to use (flames of anger), power saving and long effect of life-span.
The utility model is to adopt following technical scheme to realize: it comprises shell; water inlet, go out Ben Kou; the electric heating element parts; the overtemperature prote device; it is characterized in that described electric heating element parts are is the PTC thermistor by constant temperature heating element; battery lead plate and be positioned at the outer field thermal conductivity good insulation performance of battery lead plate layer and constitute; superficies at insulating barrier are provided with heat conduction tank (or thermal conductive water pipe of solid matter); after the energising; the heat of PTC heater can constantly be passed to the heat conduction tank through battery lead plate and insulating barrier, and the current in the heat conduction tank are heated.
The PTC constant temperature heating element (being the PTC thermistor) that the utility model adopts is a kind of high-tech product that develops rapidly in the world in recent years (an ownership sensitive ceramic), its bulk resistor is to responsive to temperature, power up (a few approximately second) at the beginning, there is big initial current (a few peace) that PTC is generated heat rapidly, temperature meets and exceeds point in the back in newspaper short time (several seconds), at this moment, because the rapid rising of PTC body resistivity, the electric current that flows through PTC is descended rapidly, but the current in the heat conduction tank are constantly taken away the heat of PTC heater again, after treating that it sets up thermal balance, its electric current just is stabilized on a certain numerical value, the heat that this electric current produces on PTC is constantly to the heating of the flowing water in the heat conduction tank, and the water temperature of delivery port can be regulated automatically with the size of flow.During use,, can flow out hot water continually just spent for 15 seconds approximately as long as the user pulls water regulating valve switch (red light on the water heater is bright).In addition, PTC also has a unrivaled advantage of other heater, that is exactly the biddability to supply voltage, make it be subjected to the influence of mains fluctuations minimum, utilize the heater that it makes, both can be used for 220 volts of civil powers, also can be used for 110 volts of civil powers and need not change-over switch and worry to burn because of wrong.
Below in conjunction with embodiment concrete structure of the present utility model is described in further detail.
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is the novel electrical schematic diagram of this reality.
Wherein: 1-water inlet, 2-heat conduction tank, 3-insulating barrier; the 4-battery lead plate; the 5-PTC thermistor, 6-power line, 7-shell; the 8-water regulating valve; 9-power switch K (with the water regulating valve interlock), 10-delivery port, 11-overtemperature prote device (K switch 1); 12-earth leakage protective device (K switch 2), 13-is luminous=utmost point pipe D (red green indicator lamp).
The utility model also has following technical characterictic when specific design is made:
One, in order to strengthen its heating efficiency and to improve result of use, this water heater can be promptly by many groups PTC thermistor, battery lead plate, insulating barrier and heat conduction tank and connect solid matter and constitute by many groups electric heating element parts.
Two, also set up on circuit and be serially connected with overtemperature prote device (K switch 1), earth leakage protective device (K switch 2), its power switch K and water regulating valve are that system is linkage structure.The purpose that adopts above-mentioned parts is for safe and reliable, and is perfectly safe.
