The above-mentioned contents of the present invention are further explained as follows:
the utility model discloses the water heater has following three kinds of mode:
one, instant heating mode: the circulating pump 3 does not work, the one-way water stop valve 4 is closed, the hot water outlet switch 14 is opened, water flows into the water flow regulating valve 13 from the tap water source water inlet 6, the pressure release valve 16, the water storage tank water inlet 5, the water storage tank water outlet 8 and the heating body water inlet 9 to enter the heating body, and then flows out from the hot water outlet 7 through the heating body water outlet 11 and the hot water outlet switch 14, in the mode, the water storage tank only serves as a water pipe, the mode is suitable for being used when the temperature of tap water is higher than 15 ℃, whether the heating body is heated or not is controlled by the water flow device 17, when the water flow device 17 detects that the water flow is larger than 0.2L/min, the heating power switch is started.
The first and the third of the three water flow channels are heated by adopting the mode.
Secondly, preheating mode is single: the preheating temperature is set firstly under the mode, the hot water outlet switch 14 is confirmed to be in the closed state, the power switch is turned on before bathing, the circulating pump 3 starts to work, the one-way water stop valve 4 is turned on under the action of water pressure, water flows through the one-way water stop valve 4, the water inlet 5 of the water storage tank, the water outlet 8 of the water storage tank, the water inlet 9 of the heating body, the water outlet 11 of the heating body and the circulating pump 3 form circulation, the water flowmeter 2 detects water flow, the heating system starts, the water flowmeter 2 cannot detect water flow until the temperature of the water inlet temperature sensor 10 of the heating body is equal to the preset preheating temperature, and at the moment. If the hot water outlet switch 14 is turned on in the preheating process, the water flow is detected by the water flow device 17, the circulating pump 3 stops working, and the water heater is switched to the instant heating mode to work.
The preheating temperature is set to be less than or equal to the bathing preset temperature, because the mode is switched to the instant heating mode when bathing, the heating body can continue to heat, if the preheating temperature is too high, the instant heating mode cannot be started, the water outlet switch 14 does not have the water mixing function, hot water waste is caused, and accidental scalding is also caused; in addition, once the hot water outlet switch 14 is turned on or the preheating temperature is reached in the mode, preheating is finished, if preheating is needed again, the power supply must be restarted, the circuit for controlling the preheating times is reset, the circulating pump 3 can work, and preheating continues.
The heating system of the heating body is controlled by the water flow meter 2 and the water flow meter 17, and the heating system is activated as soon as one of them detects a water flow.
Thirdly, a plurality of persons in a preheating mode: the difference of many people's mode and single mode is just closing hot water delivery port switch 14 at the in-process of bathing or the end of bathing, and rivers 17 can not detect rivers, and circulating pump 3 will start, and start-up back water flowmeter 2 detects rivers, and heating system work is to the hydrologic cycle heating in the water storage tank, and until the temperature reaches preheating temperature or hot water delivery port switch 14 opens, rivers are detected to rivers 17, and circulating pump 3 stop work.
It should be noted that the power is turned off immediately after the last person has finished bathing, otherwise it will cause waste.
These three kinds of modes can switch according to the demand, and control panel is last to be provided with instant heating mode, and preheating mode is single, and three button of many people of preheating mode to and every button all corresponds a work pilot lamp, selects a mode to correspond the pilot lamp and lights two other and can not work, three kinds of work system mutual independence settings.
The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose of the embodiments is to enable people skilled in the art to understand the contents of the present invention and to implement the present invention, which cannot limit the protection scope of the present invention. All equivalent changes and modifications made according to the spirit of the present invention should be covered by the protection scope of the present invention.
