Problems solved by technology

[0003] First, the vacuum glass tube is integrated with the thermal insulation water tank, which occupies a large space, and the water heater has a large workload after entering the water, so there are great limitations in the placement location, resulting in the fact that only residents on the top floor can install and use it. Solar water heaters cannot be installed or used by other users if they want to install them
[0004] Second, due to the limitation of daylighting and bulky installation of desktop solar water heaters, the installation of solar water heaters often affects the beauty and integration of urban buildings. At the same time, the safety brought by the installation of non-top users , water leakage and other social problems have led to restrictions on solar water heaters by local property management departments and relevant government departments
[0005] Third, the permanent heat exchange in the vacuum glass tube is a natural exchange in a single body tube. When the temperature is not high, the speed of this heat exchange transfer is very slow, and the heat exchange efficiency is very low.
Moreover, the water in the vacuum tube is never replaced, so its scale is serious, and its water quality continues to deteriorate over time.
[0007] Fifth, the solar water heater is placed outdoors, and the heat dissipation of the water tank is large. Under low temperature and low light in winter (such as at night), the solar water heater and the indoor water inlet and outlet pipes are easy to freeze and crack
[0008] Sixth, the water heater cannot control the water level of the water tank during the electric heating process, so the electric energy consumption in the electric heating process is large, the waste is also amazing, and the heating rate is very slow
Therefore, its practical results prove that the service life cannot exceed two years
[0011] Second, the manufacturing cost is high, and the retail price is naturally high
[0012] Third, it requires secondary heat exchange, so its thermal efficiency is not high
[0013] Fourth, in the process of electric heating, the water level in the water tank cannot be controlled, and only the whole bucket of water can be heated all the time, so the consumption of electric energy is large and the waste of electric energy is also amazing, and the heating rate is also very slow
[0014] Fifth, due to the need for high-pressure and pressure-bearing operation in the circulating metal pipeline, and the high-pressure and pressure-bearing operation in the water tank, the safety is low, and once there is a fault, the maintenance is difficult, highly professional, and the cost is also very high

Abstract

The invention mainly discloses a flat split-type solar water heater which mainly comprises a non-bearing inner machine and a flat heat-collecting outer machine. The inner machine mainly comprises a water tank, an integrating device, a bi-directional circulating pump, an electric heating bar, a photo sensor, a water level sensor, a temperature sensor and other parts including a plurality of one-way valves, a filtering valve, a plurality of control valves, multiple water inlet and water outlet pipeline ports, an automatic pressurizing pipeline and the like, and thereby an integral machine and an integral running system are formed. External light is detected via the photo sensor, and automatic control and operation of the integral system are completed by programming detecting standards of the sensors by the integrating device. The flat split-type solar water heater runs synchronously with light, utilizes the electric heating bar to keep temperature constant, and has the advantages of strong practicality, high automation degree, strong integration and the like.

Description

technical field [0001] The invention relates to a solar water heater, in particular to a flat-plate split solar water heater. Background technique [0002] As a clean and pollution-free green environmental protection device, solar water heaters are becoming more and more popular. At present, most of the popular solar water heaters on the market are desktop or pressure-bearing wall-mounted. The main form of the desktop is that the water tank is connected with the vacuum tube; the pressure-bearing wall-mounted structure is that although the water tank and the collector are separated, the vacuum tube of the collector and the water tank are connected together through a closed metal tube. The working principle of the desktop is: the vacuum glass is irradiated by sunlight, which makes the water in the tube heated and buoyant, and exchanges heat with the water in the heat preservation water tank to achieve the temperature rise of all the water. There are following defects in this...
