Abstract
The utility model discloses a heating system of an electric water heater. The heating system comprises an earth leakage protection switch, a heating disc, a power-switching circuit, a water pump and a control panel. A live wire L and a zero line N of a mains supply are connected to the two ends of the heating disc and the input end of the power-switching circuit through the earth leakage protection switch. The water pump and the control panel are connected between the positive electrode and the negative electrode of the output end of the power-switching circuit. A switch K1 and a switch K2 are arranged between the input end of the power-switching circuit and the heating disc. A switch K3 is arranged between the positive electrode of the output end of the power-switching circuit and the water pump. The heating system of the electric water heater can keep the water temperature constant within the range from 25DEG C to 50 DEG C, detect the water level and water temperature automatically and control the working state of the water pump timely and effectively according to the water amount of a water tank, thereby reducing the workload of the water pump and prolonging the service life of the water pump.
Description
Technical field
The utility model relates to a kind of heating system, particularly relates to a kind of electric water heater heating system.
Background technology
Along with improving constantly of people's living standard, water heater become indispensable electric equipment in Modern Family.The water heater the most often using has electric heater and gas heater, but along with the rise of gas price, and electric heater will be the developing direction in water heater market from now on, and electric heater has the advantages such as long, energy-efficient, safety of life-span, environmental protection.Existing electric heater in use can not be within the specific limits constant by water temperature, was prone to cold or overheated situation in bathing process; Meanwhile, in water tank lacks water situation, can not make in time water pump quit work, thereby increase the live load of water pump, shorten the service life of water pump.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of that water temperature is constant between 25 °～50 °, automatically sensed water level and water temperature, and timely and effectively according to water volume in water tank number and water temperature control the duty of water pump.
The purpose of this utility model is achieved through the following technical solutions: a kind of electric water heater heating system; it comprises earth leakage circuit-breaker, heating plate, power-switching circuit, water pump and control panel; the live wire L of mains supply and zero line N receive the two ends of heating plate and the input of power-switching circuit by earth leakage circuit-breaker; between power-switching circuit output positive and negative charge, be connected to water pump and control panel; between the input of power-switching circuit and heating plate, be provided with K switch 1, K2, between the positive pole of power-switching circuit output and water pump, be provided with K switch 3.
The ground wire PE of described mains supply is connected with inner water tank by earth leakage circuit-breaker.
It also comprises the level sensor for detection of cistern water level, and level sensor is connected with control panel by the level sensor socket being arranged on control panel.
It also comprises the cooling-water temperature sensor for detection of water tank water temperature, and cooling-water temperature sensor is connected with control panel by the cooling-water temperature sensor socket being arranged on control panel.
It also comprises display board, and display board is connected with control panel by the display board socket being arranged on control panel.
The beneficial effects of the utility model are: this system remains on the water temperature in Water tank for electrical water heater between 25 °～50 °; Can automatically detect the water yield in water tank; Water temperature in water tank is lower than 25 ° or while lacking higher than 50 ° or water volume in water tank, and water pump will quit work, thereby avoid water temperature in bathing process to cross cold or overheated phenomenon, reduce the live load of water pump, extend the service life of water pump; In bathing process, automatically cut off the 220V alternating current of heating use, adopt 24V powered by direct current, thereby guarantee the safety problem in bathing process.
Accompanying drawing explanation
Fig. 1 is the utility model structured flowchart.
The specific embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model is described in further detail, but protection domain of the present utility model is not limited to the following stated.
As shown in Figure 1, a kind of electric water heater heating system, it comprises:
Earth leakage circuit-breaker: for cutting off in time mains supply, guarantee the use safety of electric heater;
Heating plate: convert electric energy to heat energy, thus the water in heating water tank;
Power-switching circuit: convert alternating current to direct current, so that the operating voltage of water pump, control panel etc. to be provided;
Water pump: for increasing inner pipe water pressure;
Control panel: for water yield threshold values, water temperature value are set, and according to the break-make of water temperature and water level situation gauge tap.
The live wire L of mains supply and zero line N receive the two ends of heating plate and the input of power-switching circuit by earth leakage circuit-breaker; between power-switching circuit output positive and negative charge, be connected to water pump and control panel; between the input of power-switching circuit and heating plate, be provided with K switch 1, K2, between the positive pole of power-switching circuit output and water pump, be provided with K switch 3.
The ground wire PE of described mains supply is connected with inner water tank by earth leakage circuit-breaker.
It also comprises the level sensor for detection of cistern water level, and level sensor is connected with control panel by the level sensor socket being arranged on control panel.
It also comprises the cooling-water temperature sensor for detection of water tank water temperature, and cooling-water temperature sensor is connected with control panel by the cooling-water temperature sensor socket being arranged on control panel.
It also comprises display board, and display board is connected with control panel by the display board socket being arranged on control panel.
Operation principle: fill with in water tank after water, connect 220V alternating current, now heating plate converts electric energy to heat energy, thereby the water in heating water tank, when the water temperature in water tank reaches preset value, K1, K2 disconnect, and stop heating; Water temperature in water tank passes to control panel by temperature sensor, and the water temperature in water tank is lower than 25 ° or during higher than 50 °, and K switch 3 disconnects, and water pump is quit work; The water yield in water tank can pass to control panel by level sensor, and the water yield in water tank being detected is when lacking state, and control panel sends instruction disconnects K switch 3, and water pump is quit work.
