Description
Technical Field
The invention belongs to the technical field of household electric heaters, and particularly relates to a multi-device system of a tail-end water heater, which has the functions of automatic water return, sterilization and sectional heating, can be matched with a solar water heater, an air source heat pump water heater, an electric water heater, a gas water heater and other water heaters for use, can also be used independently, and is a special tail-end water heater which can change a heating area according to the amount of tail-end hot water and can provide sterile hot water and tail-end water for heating once the water is used.
Background
The prior art water heaters typically suffer from the following problems:
firstly, under the condition that the existing solar water heater, electric water heater, air source heat pump water heater and other types of water heaters do not have special water return pipes or water return devices, a section of cold water can be generated when the end-use water tap is used for water for the first time, the phenomenon is cold water which is cooled when the hot water in the pipeline between the end-use water tap and the water source of the water heater is stored for too long time, so that the phenomenon of a section of cold water can be generated when the water is used again after too long time interval, the phenomenon is particularly obvious in the application of the existing solar water heater, and the common defect that all the existing water heaters do not have water return pipes is also realized.
Secondly, the existing solar water heater is exposed to the sun and rain for a long time outdoors, so that water pipes and pipe fittings matched with solar energy are undoubtedly aged and damaged due to long-term overhaul, when the pipes or the pipe fittings are suddenly damaged, water in the water storage tank or the water replenishing tank and other pipelines in the solar water heater can be continuously leaked out, at the moment, a user can hardly find the reason that the water amount is greatly increased when water is supplied at the bottom of a month, and the waste caused by the pipeline loss of the outdoor solar water heater is undoubtedly caused.
Thirdly, most of the existing electric heaters are wall-mounted, and the potential safety hazard can be caused due to the load bearing of the existing electric heaters, so the capacity is generally within 100 liters, the temperature of hot water is usually adjusted by a temperature controller on the water heater, the layered heating technology is difficult to realize due to the wall-mounted structure, and the existing electric heat is a heating constant-temperature mode no matter the water consumption, which is undoubtedly energy loss.
Fourth, the existing water heaters have no sterilization function, and particularly, the solar water heater is easy to generate coliform bacteria and legionella after being repeatedly heated for more than 18 days, which is undoubtedly an unknown 'damage' to human bodies.
Fifthly, cold water in a heat collecting pipe of the solar water heater is heated and heated continuously by absorbing heat of the sun, the heat in the heat collecting pipe slowly rises into a solar water tank along water stored in the heat collecting pipe according to the principle of heat rising, cooling and lowering, and the biggest defect of the working principle is large resistance of natural circulation and low efficiency, which is an unsolved efficiency bottleneck of the current solar water heater.
The solar water heater and the electric water heater both adopt a microcomputer controller technology, the technology is mature and stable, and continues to the present, the defect is that the solar water heater and the electric water heater can automatically operate after being manually set on site, and the solar water heater and the electric water heater are controlled by a mobile phone WIFI (wireless fidelity), but the solar water heater and the electric water heater cannot be applied and popularized due to high cost and complex control logic.
The water tank mainly comprises a single cabin, and the water tank has the defects that when the water consumption is large or the water inlet pressure is overlarge, supplemented cold water is easy to mix into a hot water area, so that the hot water is suddenly cooled and suddenly heated.

When the storage water tank needs to be replenished with water, the implementation mode is as follows: when the water storage tank needs to be replenished with water, the ball float valve can automatically open the valve core under the action of the floating ball, at the moment, a water source can enter the water storage tank from a tap water inlet valve under the action of pressure after flowing to the water flow detector through a tap water pipeline, when the water level in the water storage tank reaches the rated water storage amount, the ball float valve can close the valve core under the action of buoyancy, and the reciprocating action forms a pipeline of a complete water replenishing working principle of the water storage tank.

When the solar water heater also needs forced heating, namely when the water consumption exceeds the rated water consumption and auxiliary heating needs to be started in rainy days, the solar auxiliary heating rod is controlled by the solar controller, namely the auxiliary electric heating rod is started when the lower limit water temperature is set, and the auxiliary heating rod is stopped when the water temperature is greater than the upper limit, so that a set of complete solar water heater auxiliary heating control logic program is formed.
At present, the non-pressure-bearing solar water heater continuously transfers the light and heat absorbed by the sun to cold water in the heat collecting pipe by the heat collecting pipe, and the cold water in the heat collecting pipe is continuously heated to raise the temperature of hot water, thereby forming a continuous cold and heat exchange process.
Since the solar water heater appeared at the end of the 70 s, the natural heat-throwing circulation mode has not been improved, and the natural circulation has the defects that the hot water rises and is subjected to the resistance of sinking of the cold water, and the natural circulation efficiency is reduced.

The temperature-resistant silica gel ferrule ensures that the upper and lower circulation guide pipe assemblies and the inner hole of the heat collecting pipe form sealing, and aims to install an upper circulation guide pipe and a lower circulation guide pipe, wherein the upper circulation guide pipe is made of thin-wall stainless steel and is semicircular in shape, so that a circulation guide channel is enlarged as much as possible, and the pipe is shorter than the lower circulation guide pipe. The lower circulation flow guide pipe is a thin-wall stainless steel pipe and is semicircular in shape, the purpose is to enlarge a circulation channel as much as possible, and the pipe is determined according to the length of the heat collecting pipe. The installation implementation mode is that the planes of the upper circulation flow guide pipe and the lower circulation flow guide pipe are combined and welded into a whole, the periphery of the joint of the planes is circular, and then the temperature-resistant silica gel sleeve is sleeved on the circular position to form a complete unpowered circulation flow guide pipe assembly device assembly of the heat collection pipe.
