The photovoltaic water heater comprises a heat preservation inner container, a water mixing valve and a controller, wherein an electric heating pipe is arranged in the heat preservation inner container; a water inlet pipe communicated with an external tap water pipe and a water outlet pipe communicated with a hot water port of the water mixing valve are arranged at the bottom of the heat preservation inner container, a first electromagnetic valve controlled by the controller is arranged on the water inlet pipe, and a second electromagnetic valve controlled by the controller is arranged on the water outlet pipe; a cold water port of the water mixing valve is communicated with the external tap water pipe, and the water mixing valve is also provided with a water outlet; a water level lower limit sensor and a water lever upper limit sensor are arranged in the heat preservation inner container, wherein the signal output end of each of the sensors is electrically connected with the controller, and the sensors are positioned above the electric heating pipe; a booster pump is arranged on the top of the heat preservation inner container; and the controller is provided with a rechargeable battery, and the input end of the rechargeable battery is connected with the output end of a photovoltaic battery. By adopting the photovoltaic water heater, boiled hot water can be fully utilized; and cold water is prevented from being added when the hot water is discharged, so that resource waste is avoided.
Description
Technical field
The present invention relates to a kind of photovoltaic type water heater that improves heat utilization ratio, belong to technical field of water heaters.
Background technology
Understand according to the applicant, existing water heater is in order to keep the heat outputting water pressure, usually directly utilize the pressure of running water pipe, but so must constantly be filled with cold water in inner bag when output hot water, hot water temperature's straight line burned in original inner bag is descended, have to continue heating its temperature is raise, this is undoubtedly the waste to resource.
Summary of the invention
Technical problem to be solved by this invention is: overcome the problem that prior art exists, a kind of photovoltaic type water heater that improves heat utilization ratio is provided, avoid the wasting of resources by taking full advantage of burned hot water.
The technical scheme that the present invention solves its technical problem is as follows: a kind of photovoltaic type water heater that improves heat utilization ratio, it is characterized in that, and comprise heat-preservation liner (1), mixed water valve (11) and controller (3), be mounted with electrothermal tube (2) in heat-preservation liner (1); Heat-preservation liner (1) bottom has the water inlet pipe (4) that is communicated with outside running water pipe (10), the outlet pipe (5) that is communicated with mixed water valve (11) hot water mouth, water inlet pipe (4) has the first magnetic valve (9) that is controlled by controller (3), and outlet pipe (5) has the second magnetic valve (8) that is controlled by controller (3); Mixed water valve (11) cold water outlet is communicated with outside running water pipe (10), and mixed water valve (11) also has delivery port; Be provided with signal output part was electrically connected to respectively and was positioned at electrothermal tube (2) top with controller (3) water level lower limited sensor (7), water level upper limit sensor (6) in heat-preservation liner (1); Heat-preservation liner (1) top is provided with force (forcing) pump (12); Controller (3) has rechargeable battery, and the rechargeable battery input is connected with photovoltaic cell (13) output.
The present invention can take full advantage of burned hot water, avoids adding cold water in emitting the process of hot water, thereby avoids the wasting of resources; Adopt photovoltaic cell directly to utilize solar energy, make whole water heater be adapted at using in the inadequate or power free situation of voltage, thereby enlarge the water heater scope of application.
Description of drawings

The specific embodiment
With reference to the accompanying drawings and in conjunction with the embodiments the present invention is described in further detail.But the invention is not restricted to given example.
Embodiment
The photovoltaic type water heater basic structure that the present embodiment improves heat utilization ratio comprises heat-preservation liner (1), mixed water valve (11) and controller (3) as shown in Figure 1, is mounted with electrothermal tube (2) in heat-preservation liner (1); Heat-preservation liner (1) bottom has the water inlet pipe (4) that is communicated with outside running water pipe (10), the outlet pipe (5) that is communicated with mixed water valve (11) hot water mouth, water inlet pipe (4) has the first magnetic valve (9) that is controlled by controller (3), and outlet pipe (5) has the second magnetic valve (8) that is controlled by controller (3); Mixed water valve (11) cold water outlet is communicated with outside running water pipe (10), and mixed water valve (11) also has delivery port; Be provided with signal output part was electrically connected to respectively and was positioned at electrothermal tube (2) top with controller (3) water level lower limited sensor (7), water level upper limit sensor (6) in heat-preservation liner (1); Heat-preservation liner (1) top is provided with force (forcing) pump (12); Controller (3) has rechargeable battery, and the rechargeable battery input is connected with photovoltaic cell (13) output.
Running is as follows:
The first step, send the heating instruction to controller (3); Controller (3) opens the first magnetic valve (9) and cuts out the second magnetic valve (8), and running water enters heat-preservation liner (1) through water inlet pipe (4); Prescribe a time limit when water level rises to, water level upper limit sensor (6) sends signal to controller (3), and controller (3) cuts out the first magnetic valve (9); Then, controller (3) is opened electrothermal tube (2) the heating scheduled time (t1) and is obtained hot water, and controller (3) cuts out electrothermal tube (2);
Second step, send the water outlet instruction to controller (3); Controller (3) is opened the second magnetic valve (8) and force (forcing) pump (12); The mixed water valve (11) of operation can be emitted hot water;
The 3rd goes on foot, prescribes a time limit when water level drops to, water level lower limited sensor (7) sends signal to controller (3), controller (3) is opened the first magnetic valve (9), running water enters heat-preservation liner (1) through water inlet pipe (4), same Time Controller (3) is opened electrothermal tube (2) the heating scheduled time (t2), and controller (3) cuts out electrothermal tube (2) afterwards; Prescribe a time limit when water level rises to, water level upper limit sensor (6) sends signal to controller (3), and controller (3) cuts out the first magnetic valve (9), and enters for the 4th step;
The 4th step, controller (3) detect whether receive END instruction, if controller (3) cuts out the first magnetic valve (9), the second magnetic valve (8), force (forcing) pump (12), reaches electrothermal tube (2), end of run; Entered for the 3rd step if not.
