Problems solved by technology

[0002] The obliquely inserted compact vacuum tube solar water heater is the household solar water heating device with the largest output and the highest penetration rate in my country. The "cross-century problem" that has been effectively solved:
[0003] 1. The hot water pipes of the system cannot be automatically emptied with a delay. Every time the valve is opened to take water, it will cause a large amount of waste of the remaining water resources for heat dissipation in the pipes.
[0004] 2. The lower the residential floor, the longer the hot water pipe, the more serious the waste of water resources
[0005] 3. In the thermal insulation circulating water tank, there is a "dead water area" below the nozzle of the vacuum tube that cannot effectively participate in the temperature difference cycle heat exchange. A large amount of dirt and impurities will be deposited in the "dead water area" for a long time, and some will even seriously affect the water quality. Hazardous substances for hygiene and physical health
[0006] 4. The cold and hot water pipes of the hot water system exposed to the outdoor environment do not have the function of anti-cold and anti-freeze. In the deep and severe cold of the long winter in the north, it is difficult to guarantee that the pipes, water tanks, or vacuum pipes will not be damaged by freezing
It is a pity that decades have passed, and in the same type of products mass-produced in Shanghai, the world's largest solar market, there has not been a simple, reliable and low-cost solution to the so-called "valve opening, hot water coming in". ", "dead water area" sewage, anti-cold, hot water pipes and water tank freeze damage, and other reports on innovative technological achievements

Embodiment Construction

[0020] For any so-called "obliquely inserted compact vacuum tube solar water heater" composed of an all-glass vacuum tube collector, a circular horizontal thermal insulation heat storage circulating water tank and the relevant tripod system "three major assembly parts", in principle, all The technical route and method provided by the present invention can be used to transform it into a domestic solar water heater with functions such as "valve opening, hot water coming", simple sewage discharge for indoor control, anti-freezing damage, etc.

[0021] according to figure 1 The structural diagram of the water supply and drainage pipeline system shown in the figure shows the technical transformation of the pipe network of the vacuum tube water heater system and the system works like this: when we open the main tap water valve 1, the tap water bypasses the control valve 2 of the sewage pipe and officially enters the system. In the cold water upper pipe 14 of the hot water system, bu...

Abstract

The invention discloses a water saving, pollution discharge and freeze prevention type vacuum tube solar water heater. Based on traditional system components of an inclined insertion type compact vacuum tube solar water heater, a physicals principle is applied to optimally design and adjust the layout of water tank water inlet and outer pipes, overflow and air release pipes, a pollution discharge pipe and water feeding and draining systems, and a water saving function of valve opening-hot water running is realized under the preconditions of no consumption of auxiliary energy and no adding of energy consumption devices; the targeted self-cleaning pollution discharge is performed for a dead water area of an insulation water tank through indoor hand control; cold and hot water pipes are emptied; and the total volume of the insulation water tank is automatically reduced below a safe water level to prevent freeze injury accidents. The water saving, pollution discharge and freeze prevention type vacuum tube solar water heater reduces the production cost, improves the product structure, optimizes the product use performance, saves the clean water resource, and promotes the product market competitiveness.

Description

technical field [0001] The invention relates to the field of solar light and heat utilization, and is a technical method capable of upgrading the obliquely inserted compact vacuum tube solar water heater technology to have the basic functions of "valve opening, hot water coming", sewage discharge and antifreeze. Background technique [0002] Inclined plug-in compact vacuum tube solar water heaters are the household solar water heaters with the largest output and the highest penetration rate in my country. The "cross-century problem" that has been effectively solved: [0003] 1. The hot water pipes of the system cannot be automatically emptied with a delay. Every time the valve is opened to take water, it will cause a large amount of waste of the remaining water resources for heat dissipation in the pipes. [0004] 2. The lower the floor of the household, the longer the hot water pipe, the more serious the waste of water resources will be. [0005] 3. In the thermal insulati...
