Only the manufacturer technology backend has the right to start.

The invention works as follows:

first, the present invention provides the basic function, and the pipe cold water free function, pressurized water outlet and circulating anti-freezing device that is placed between and integrated with the tank liner and the tank shell. The novel solar water heater comprises: the water tank comprises a water tank shell, an inner container, a water inlet, a water outlet, a water return port, an electric heating port, an air outlet, an electromagnetic valve, a temperature sensor, a water inlet and outlet pipeline and a water return pipeline.

Secondly, the pipeline has no cold water function: when the temperature is lower than 45 ℃, the control module sends out instructions of opening the water pump and opening the electromagnetic valve for 10 seconds to 20 minutes, and the water pump and the electromagnetic valve are opened; after 10 seconds to 20 minutes, the electromagnetic valve is closed, the control module continuously detects whether a user opens the hot water valve to use hot water through the water flow sensor, if so, the water pump is continuously opened, and if not, the water pump is closed. At the moment, the temperature of water in a pipeline from the solar water heater to a water using end of a user is close to the temperature of the solar water heater, so that the user can directly use hot water by opening a hot water valve after more than 10 seconds (the time is determined by the length of the pipeline), and the user feels the effect of increasing the lift of a water pump, the whole process is completed within 10 seconds to 2 minutes, and the water outlet quantity of the water pump is determined.

Thirdly, hot water pressurization function: when a user opens the hot water valve, the water flow sensor transmits a signal to the control module, the control module gives an instruction for opening the water pump, and when the temperature of the pipeline is higher than 45 ℃, the electromagnetic valve is not opened, so that the user can smoothly use the water outlet pressure of the pump lift, which is generally higher than 0.1-0.15MPa (the pump lift of the water pump is increased by the height of the floor).

Fourthly, the pipeline anti-freezing function: in winter, when the control module detects the solar water heater through the temperature sensor, the hot water valve is closed, and the control module detects that the water temperature in the water inlet and outlet pipeline or the water return pipeline is less than or equal to 1-7 ℃ through the temperature sensor, the control module sends an instruction for opening the water pump and the electromagnetic valve for 1-20 minutes, the water pump and the electromagnetic valve are stopped after being opened for 1-20 minutes, meanwhile, the control module continuously detects the temperature of the water inlet and outlet pipeline or the water return pipeline through the temperature sensor, water in the water tank circulates among the water inlet and outlet pipeline, the water return pipeline and the water tank, and the water temperature in the water inlet and outlet pipeline and the water return pipeline continuously; the control module continuously detects the temperature of the water inlet and outlet pipeline or the water return pipeline through the temperature sensor, and when the control module detects that the temperature of water in the water inlet and outlet pipeline or the water return pipeline continuously rises, the control module prepares to enter the next period for work; when the control module detects that the temperature of water in the water inlet and outlet pipeline cannot rise through the temperature sensor, the control module does not start the next circulation until the water flow sensor transmits a signal to the control module.

In the northern cold region, when the hot water valve is closed and the control module detects that the water temperature in the water inlet and outlet pipeline or the water return pipeline is less than or equal to 1-7 ℃ through the temperature sensor, the control module sends an instruction for opening the water pump, the electromagnetic valve and the electric heater for 1-20 minutes, the water pump, the electromagnetic valve and the electric heater are stopped after being opened for 1-20 minutes, meanwhile, the control module continuously detects the temperature of the water inlet and outlet pipeline or the water return pipeline through the temperature sensor, water in the water tank circulates among the water inlet and outlet pipeline, the water return pipeline and the water tank, and the water temperature in the water inlet and outlet pipeline and the water return pipeline continuously rises; the control module continuously detects the temperature of the water inlet and outlet pipeline or the water return pipeline through the temperature sensor, and when the control module detects that the temperature of water in the water inlet and outlet pipeline or the water return pipeline continuously rises, the control module enters the next period to work; when the control module detects that the temperature of water in the water inlet and outlet pipeline cannot rise through the temperature sensor, the control module starts the next cycle until the water flow sensor transmits a signal to the control module.

The heat collecting system of the solar water heater can be shown in fig. 2 and comprises a water tank, a control module 6, a water return pipeline 15, a temperature sensor 13, a water flow sensor 3, a signal processing module, a signal transmission module, a water pump 5, an electromagnetic valve 12, a hot water valve 16, a connecting pipeline and the like.

The water tank is connected with an electric heater 17, and the electric heater 17 is connected with the control module 6 through a control line.

The working process of the heat collecting system of the solar water heater is as follows:

the signal processing module works or not, the management service module determines whether the signal processing module works or not, the management server solves the business flow of the front end, such as purchasing service, giving service and the like, the management service module sends out instruction signals of whether the signal processing module is used or not, the use duration and the use period, and the instruction signals are sent to the signal processing module through the network server and the signal transmission module.

Under the condition that a user does not pay, the management service module sends out a use stopping signal, when the signal processing module receives the use stopping signal, the control module, the water pump and the electromagnetic valve do not work, but the solar water heater can still normally provide a hot water supply mode which is equivalent to that of a common pressure-bearing or non-pressure-bearing compact solar water heater, can be continuously used, but can not realize instant heating without an anti-freezing function.
