Solar water heater device integrating functions of automatic water loading and automatic water pipe emptying

Abstract

The invention discloses a solar water heater device integrating the functions of automatic water loading and automatic water pipe emptying. The solar water heater device comprises a heat-insulating water tank, a temperature-regulating valve and an intelligent control instrument and a tap water pipe, wherein the heat-insulating water tank is communicated with the tap water pipe through a water service pipe; an upper emptying valve and a lower emptying valve are mounted on the water service pipe and are electrically connected with the intelligent control instrument respectively; two limber holes communicated with emptying ports are opened so as to discharge water in an upper water service chamber and a lower water service chamber through the emptying ports of the emptying valves below the upper water service chamber and the lower water service chamber, so that the frost splitting of water pipes are prevented, which guarantees the normal use of solar energy in freezing winter.

Description

technical field [0001] The invention relates to a solar water heater with an automatic emptying function, in particular to an integrated device for automatic water supply of the solar water heater and automatic emptying of water pipes. Background technique [0002] Solar water heaters are deeply loved by people due to the advantages of saving non-renewable energy, safety and sanitation, and convenience, and are gradually widely used in urban and rural areas. [0003] The switch control valve on the existing solar water heater is generally a two-way type, that is, only a water inlet and a water outlet are provided. In the body, it cannot be discharged, resulting in the waste of hot water. In winter, due to the low temperature, the water pipes can be blocked or cracked by freezing, which will affect the use. [0004] There are mainly two types of solutions currently available: the first type is to add insulation to the water pipe and add an electric heating belt along with t...

Problems solved by technology

[0005] The first is artificial thawing. Once the pipeline is frozen and blocked, the power supply of the electric heating belt is manually connected to heat the frozen and blocked water pipe to melt it. It consumes a certain amount of electricity, and it takes a while to melt when using water, and the water pipes are often swelled and cracked.

[0006] The second is automatic antifreeze, add a set of intelligent automatic temperature control device, the temperature control probe detects the temperature of the water pipe, when the temperature is low to a certain level, it will automatically turn on the power to make the electric heating belt work, so that the water pipe will not be lower than 0 ℃, This kind of electric heating has the disadvantages of high cost, high installation cost, and high energy consumption during use.
