Sub-depot flow-guiding type solar water heater

Abstract

The invention relates to a sub-depot flow-guiding type solar water heater water tank with simple structure and good insulating and energy-saving effects, comprising a water tank body and a vacuum pipe, wherein the water tank body is connected with the vacuum pipe; the water tank body is provided with a water inlet and a water outlet; the water inlet is provided with an automatic water supplying device; an exhaust valve is arranged above or on the side wall of the water tank body; the water tank body is internally divided into a heating depot and a water storing depot by a heat insulating device; the water inlet is positioned at the water storing depot and the water outlet is positioned at the heating depot; the heat insulating device is provided with a flow-guiding pipe communicating the heating depot and the water storing depot; the exhaust valve is respectively arranged above or on the side wall of the heating depot and the water storing depot; and the water inlet is provided with the automatic water supplying device. The solar water heater water tank is designed in a sub-depot manner, stores heat and heats in the sub-depot manner, and separates transmission of the water temperature of the two depots by the heat insulating device; an electric heating device heats the heating depot, and play the roles of saving energy and protecting environment, wherein the heated amount is same as the used amount;, thus solving the difficulty that the electricity amount is large when electric heating is started in winter and cloudy and rainy days.

Description

Technical field: [0001] The invention relates to a solar water heater water tank, in particular to a sub-compartment diversion type solar water heater. Background technique: [0002] Solar energy is both primary energy and renewable energy. It is rich in resources, can be used for free, does not need to be transported, and has no pollution to the environment. However, solar energy also has two main disadvantages: one is low energy flow density; the other is that its intensity cannot be maintained constant due to the influence of various factors (season, location, climate, etc.), so there is a problem that it is not easy to use in winter and rainy weather. In order to solve this problem, the industry mostly inserts electric heating devices in the solar water heater water tank to heat the insufficient warm water in the water tank. Although this can solve the problem of raising the water temperature, people’s water consumption is relatively reduced in winter and rainy weather...

Problems solved by technology

However, solar energy also has two main disadvantages: one is low energy flow density; the other is that its intensity cannot be maintained constant due to the influence of various factors (season, location, climate, etc.), so there is a problem that it is not easy to use in winter and rainy weather

Although this can solve the problem of raising the water temperature, people’s water consumption is relatively reduced in winter and rainy weather. At this time, heating the 100 liters of water on the entire water tank is time-consuming and power-consuming, and it is a waste. Purpose

Therefore, it is necessary to develop separate warehouse solar water heaters to solve the problem that solar water heaters are not easy to use in winter and rainy weather
