Detailed Description
According to the anticorrosion method for the inner container of the solar water heater, the solar panel is additionally arranged on the outdoor heat collector of the solar water heater, solar power generation is performed by using the solar panel, and for the inner container, electric energy generated by the solar panel can be used for acting on the inner container of the solar water heater to form current for current anticorrosion protection.
Particularly, under the environment condition that has illumination daytime, solar cell panel utilizes the sunlight illumination to produce the electric energy, and the produced electric energy of solar cell panel can carry out the electric current anti-corrosion to the inner bag and handle, need not to dispose the magnesium stick in the inner bag, both can avoid the condition that leads to quality of water hardening because of adopting the magnesium stick, can reduce user's in later stage use cost again. The specific configuration of the current anti-corrosion treatment for the liner can refer to the current anti-corrosion arrangement mode in the prior art, and is not limited herein.
Further, aiming at different inner containers, a set potential value E0 for triggering current corrosion prevention is obtained through a test in a factory stage and is stored in an electric control board of the solar water heater, a sensor for detecting the potential of the inner container is correspondingly arranged on the inner container, and the specific corrosion prevention control process is as follows: the sensor detects the real-time potential value Et of the inner container and transmits the real-time potential value Et to the electric control board, the electric control board compares the detected real-time potential value Et with a stored set potential value E0, if Et > E0, the possibility of corrosion prevention of the inner container is indicated, and at the moment, the electric energy generated by the solar panel is utilized to carry out current corrosion prevention protection on the inner container; and when the sensor detects that the real-time potential value Et of the inner container is less than or equal to E0, the solar water heater stores the electric energy generated by the solar panel.
Specific control modes of the solar water heater provided with the solar panel and the storage battery can be divided into the following two types: the first mode is that the electric energy generated by the solar panel is firstly stored in the storage battery, and then the storage battery carries out current anti-corrosion operation on the inner container; the second mode is that the electric energy generated by the solar panel directly carries out the current anti-corrosion operation on the inner container, the rest electric energy is stored in the storage battery, and the storage battery assists in carrying out the current anti-corrosion operation on the inner container according to the requirement.
The first control method for corrosion prevention is as follows: the electric energy generated by the solar panel is stored in the storage battery; if Et > E0, the battery discharge protects the inner container from corrosion by current. Specifically, in the daytime under the illumination environment, the solar panel generates electricity, the generated electricity is stored in the storage battery, and the electric control board controls whether the storage battery performs the discharging operation according to the real-time potential value Et detected by the sensor. In the process of corrosion prevention, in the case of Et > E0, the electric energy applied to the inner container by the storage battery is increased along with the increase of the difference value between Et and E0.
The second control method for corrosion prevention is: if Et is greater than E0, the electric energy generated by the solar panel directly carries out current anti-corrosion protection on the inner container; if Et is less than or equal to E0, the electric energy generated by the solar panel is stored in the storage battery. Specifically, the electric control board of the solar water heater controls the solar panel to directly perform current anti-corrosion treatment on the inner container according to the real-time potential value Et of the inner container detected by the sensor, or stores electric energy in the storage battery. Preferably, in order to more reasonably utilize the electric energy generated by the solar panel, the real-time voltage value generated by the solar panel is Ut, and the potential difference of the inner container is delta U = E t-E0; when Ut is greater than delta U, the electric energy generated by the solar cell panel meets the requirement of current anti-corrosion protection on the inner container, and meanwhile, the residual electric energy charges the storage battery, so that effective current anti-corrosion treatment on the inner container is guaranteed, the electric energy can be effectively collected, more importantly, the phenomenon of hydrogen embrittlement caused by excessive current generated by overlarge applied voltage on the inner container can be avoided, and the anti-corrosion effect can be improved. When Ut is less than delta U, the solar cell panel and the storage battery simultaneously carry out current anti-corrosion protection on the inner container, when the electric energy generated by the solar cell panel cannot meet the requirement of current anti-corrosion of the inner container, the storage battery also applies voltage to the inner container, and the solar cell panel and the storage battery are matched to carry out current anti-corrosion protection on the inner container.
Based on the two control methods, the solar panel cannot generate electric energy at night or in rainy weather environment, and at the moment, if Et is greater than E0, the electric energy of the storage battery is used for carrying out current anti-corrosion protection on the inner container. Specifically, under the condition that the solar cell panel does not generate electric energy, the storage battery supplies power to the inner container to perform current anti-corrosion protection, so that the inner container is ensured to be in a long-acting anti-corrosion state. Preferably, the inner container is internally provided with a heat conducting piece, and the end part of the heat conducting piece exposed outside the inner container is connected with the thermoelectric generator; the thermoelectric generator generates power by utilizing the temperature difference between the water temperature of the inner container and the external environment temperature and charges the storage battery. Particularly, under the condition of illumination, the water temperature in the inner container is high, the thermoelectric generator can generate electricity by utilizing the temperature difference between the inside and the outside of the inner container, more importantly, under the condition of no illumination, the thermoelectric generator can continue to generate electricity by utilizing the temperature difference between the inside and the outside of the inner container, and the electric energy generated by the thermoelectric generator can continue to carry out anti-corrosion protection on the inner container so as to improve the anti-corrosion performance. And under the condition that the electric energy output by the storage battery and the thermoelectric generator cannot meet the requirement of corrosion prevention of the inner container in the non-illumination state, if Et is greater than E0, the electric control board charges the storage battery through commercial power so as to ensure that the inner container always obtains good current corrosion prevention protection.
Compared with the prior art, the invention has the advantages and positive effects that: utilize solar energy to generate electricity through solar cell panel, the produced electric energy of solar cell panel can carry out the electric current anticorrosion to the inner bag and handle to need not to adopt the magnesium stick to carry out anticorrosive, avoid quality of water sclerosis, improved bathing experience nature and reduce use cost, effectual improvement user experience nature.
Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
