Embodiment Construction

[0030] Please see figure 2 , is a structural schematic diagram of the first embodiment of the present invention. This example is in figure 1 It is obtained by making several improvements on the basis of the prior art described above. figure 2 neutralize figure 1 The same part uses figure 1 The label is shown. The following combination figure 2 The structure of this solar water heater will be described.

[0031] The main components of the solar water heater include a water tank 101, a heat collector 104, and other accessory components.

[0032] The lower part of the water tank 101 is connected to the water inlet of the heat collector 104 through the water outlet pipe 107 , and the water outlet of the heat collector 104 is connected to the upper part of the water tank 101 through the water return pipe 108 . In the installation position, the heat collector 104 is higher than the water tank 101 (under the prior art, there is no such requirement for the installation posit...

Abstract

This invention discloses a sort of the soar water heater. It consists of the water tank, the heat collector. The infrastructure of the water bank connects with the water inlet of the heat collector bythe outlet pipe, the outlet port of the heat collector connects with the superstructure of the water tank by the return line, and it is fitted a water pump in the outlet pipe in this invention, the position of the heat collector in this invention is hyper-water tank in this invention, the lower position of the water pipe in this invention connects with the downcomer that the exit locates adown bythe three-port valve. This three-way valve consists of two valve, the first valve connects with the downcomer pipeline, the second valve connects with the outlet pipeline witch is between the downcomer and the water tank. When the three-port valve is electrified, the first valve closes and the second valve conducts. When the three-port valve is loss the current, the first valve conducts and the second valve closes. The soar water heater can remove the problem that it consumes the energy to prevent frostbite and stifled used the existing technique and it can obtain the effect in preventing frostbite and stifled in the estate of no electricity all the same.

Description

technical field [0001] The invention relates to a water heater, in particular to a solar water heater. Background technique [0002] Extensive utilization of renewable resources such as wind energy and solar energy is an important part of building a conservation-minded society, and solar water heaters are an important way to utilize solar energy. [0003] Please see figure 1 , which shows a schematic diagram of the piping structure of a general-purpose primary cycle pressurized solar water heater in the prior art. This solar water heater comprises water tank 101, has the liner 102 of directly storing water in the water tank 101, and the lower part of water tank connects the water inlet of heat collector 104 through water outlet pipe 107, and the water outlet of this heat collector 104 connects water tank 101 through return pipe 108. A water pump 103 is installed near the outlet of the water tank 101 in the water outlet pipe 107 ; a temperature sensor 105 is installed in th...
