Intelligent anti-freezing solar water heater

Abstract

The invention discloses an intelligent anti-freezing solar water heater. The intelligent anti-freezing solar water heater comprises a water tank and is characterized in that the interior of the water tank is divided into a water purifying cavity, a water storage cavity and a heat storage cavity, a water inlet pipe is arranged at the left end of the water purifying cavity, a first electromagnetic valve is arranged at a position, close to the water purifying cavity, of the water inlet pipe, the tail end of the water inlet pipe is connected with a tap water pipe or a water pump and further connected with a liquid discharge pipe, a second electromagnetic valve is mounted on the liquid discharge pipe, a first flowmeter is mounted in the water inlet pipe, a water outlet pipe is arranged on the lower side of the heat storage cavity, a third electromagnetic valve is mounted at a positon, close to the heat storage cavity, of the water outlet pipe, a second flowmeter is arranged in the water outlet pipe, a communicating vessel is arranged on the water outlet pipe, a purifying device is arranged in the water purifying cavity and comprises a quartz sand filtering device, an activated carbon filtering device and a cation softening device which are sequentially arranged from left to right, and a medical stone plate is arranged on the right of the purifying device. The intelligent anti-freezing solar water heater is simple in structure, convenient to use, capable of achieving intelligent freezing preventing and capable of fast discharging hot water and has a purifying function.

Description

technical field [0001] The invention relates to the technical field of water heaters, in particular to an intelligent antifreeze solar water heater. Background technique [0002] At present, due to the remarkable effect of energy saving and environmental protection, the application of solar water heaters is becoming more and more extensive. A solar water heater is a device that converts sunlight energy into heat energy, and heats water from low temperature to high temperature to meet the needs of hot water in people's life and production. Solar water heaters are divided into vacuum tube solar water heaters and flat plate solar water heaters according to their structure, and vacuum tube solar water heaters are the main ones, accounting for 95% of the domestic market share. Vacuum tube household solar water heaters are composed of heat collecting tubes, water storage tanks, brackets and other related parts. The conversion of solar energy into heat mainly depends on vacuum hea...

Problems solved by technology

The water tank structure of the traditional solar water heater has the following disadvantages: the water entering the water tank sinks due to the low temperature, mixes with the original hot water in the water tank, reduces the temperature of the original water in the water tank, and makes the use of higher temperature water Low efficiency and high energy consumption; and it takes a long time for the water temperature on the water outlet side of the water tank to increase, resulting in slow water outlet speed

And it is easy to generate dirt in the vacuum heat collecting tube

Scale is a complex salt, which contains halogen ions, which has a corrosive effect on iron at high temperatures. The erosion of scale will make the inner wall of the metal brittle and corrode continuously to the depth, corroding the inner wall of the metal, thereby reducing its service life
