Abstract
The utility model discloses a solar water heater which comprises a heat collector installed outdoors, a water tank, a temperature difference circulating pump and a controller, wherein the water tank, the temperature difference circulating pump and the controller are installed indoors. The water tank is communicated with the heat collector through an upper circulating tube, one end of the temperature difference circulating pump is communicated with the water tank, the other end of the temperature difference circulating pump is communicated with the heat collector through a lower circulating pump, and the controller is in electric connection with the temperature difference circulating pump. The solar water heater further comprises a supercooling protector and an electric heating part, wherein the electric heating part is installed in the water tank, the inside of the heat collector and the inside of the water tank are respectively provided with a temperature probe, the temperature probes are in electric connection with the supercooling protector, and the supercooling protector, the electric heating part and the controller are in electric connection. According to the solar water heater, by means of the temperature difference between the heat collector and the inside of the water tank, hot water in the water tank enters the heat collector in a reverse circulating mode, on the situation that the outdoor temperature is exceedingly low, the heat collector can be prevented from being frozen and broken, and accordingly the heat collector can be normally used at the temperature of 40 DEG C below zero.
Description
Technical field
The utility model relates to technical field of solar, particularly a kind of solar water heater.
Background technology
Heat collector is solar water heater critical piece, and heat collector is generally all arranged on outdoor, while using in the winter time, because outdoor temperature is lower, easily causes heat collector to be damaged by frost.General anti-icing fluid system or the emptying system of adopting in industry, anti-icing fluid system is ℃ following in temperature-10 is just difficult to operation, and because heat collector is arranged on outdoorly, anti-icing fluid easily leaks, and causes environmental pollution; Emptying system is mainly the moisture content in emptying heat collector, and due to structure and the installation question of heat collector itself, in heat collector, easy residual water part, causes valve or frost crack pipe.
Summary of the invention
Based on this, the utility model is to overcome the defect of prior art, and a kind of solar water heater is provided, and is intended to solve the too low and problem that causes heat collector to be damaged by frost of outdoor temperature.
Its technical scheme is as follows:
A kind of solar water heater, comprise and be arranged on outdoor heat collector and be arranged on indoor water tank, temperature-difference circulation pump, controller, water tank is communicated with by upper circular tube with heat collector, temperature-difference circulation pump one end is communicated with water tank, the other end is communicated with heat collector by lower circulation pipe, controller is electrically connected to temperature-difference circulation pump, also comprised cold protector, electric heating part, described electric heating part is arranged in water tank, described heat collector, temp probe is all installed in water tank, described temp probe is electrically connected to the cold protector of mistake, cross cold protector, electric heating part is all electrically connected to controller.
Preferably, the cold protector of described mistake is recycled back switch.
Preferably, described solar water heater also comprises and is arranged on indoor display screen, and described display screen is electrically connected to controller.
Below the advantage of aforementioned techniques scheme or principle are described:
Described solar water heater is popped one's head in by equal set temperature in heat collector, water tank; temperature in water tank is than the temperature in heat collector during higher than particular value; cross cold protector and sent cold guard signal to controller; controller drives temperature-difference circulation pump inverted running; water heating in electric heating part automatic water-supplying tank simultaneously; hot water in water tank pumps in heat collector by temperature-difference circulation pump; pass through hot water circuit; avoid in the situation that outdoor temperature is too low; heat collector is damaged by frost, and heat collector also can normally be used under the condition of-40 ℃.
