Technical Field
[0001] The utility model relates to the technical field of water heaters, in particular to a quick-heating photovoltaic water heater. Background Art
[0002] Photovoltaic water heater, referred to as "photovoltaic energy", also known as "photovoltaic central water heater". Photovoltaic water heater uses the electricity converted from sunlight into hot water, and heats the water through photovoltaic electric heating rods for hot water and heating. The cost of energy consumption is almost zero. Only in rainy weather will it be used in conjunction with a small amount of "valley electricity" for complementary heating, which is both environmentally friendly and energy-saving.
[0003] For example, the authorization announcement number "CN216448373U" is named as a fast-heating photovoltaic water heater. Although the constant temperature device and the rapid heating device ensure that the temperature of the water is constant when it comes out, realize the functions of fast heating, constant temperature and capacity expansion, and make full use of the electricity generated by the photovoltaic panel components, the water heater can be heated by the electricity stored in the battery when the sunlight is insufficient, but it still exists. Because the fast-heating photovoltaic water heater uses photovoltaic components to absorb sunlight to generate electricity to heat the water source of the water heater, when the water heater is not in use, the internal circulation heating will ensure the output of hot water. However, the repetitive heating cycle will cause a large amount of heat to be dissipated and wasted. Before using the fast-heating photovoltaic water heater, you need to wait for the water heater to heat the water to a certain temperature before you can use it. This creates a waiting time for the water heater. During the waiting period, if it is cloudy, the water heater can only rely on indoor AC power for heating. The heating speed is very slow and wastes electricity. There is no hot water available in a short time, which affects the efficiency of the fast-heating photovoltaic water heater.
[0004] At the same time, the existing instant-heating photovoltaic water heaters use batteries to absorb excess heat from solar energy and store it for heating the inside of the water heater. However, the rapid heating device should be the instant heating heater currently on the market. In order to ensure the heating speed, the power of the instant heating heater will be very large during operation. Therefore, relying on batteries to power the high-power rapid heating device will cause excessive load on the wires and easily burn out the circuit components, which will not only damage the water heater, but also easily cause fire hazards, thereby improving the safety of the instant-heating photovoltaic water heater.

[0032] Working principle:
[0033] First, when there is sufficient sunlight, the connecting line 71 will transmit electric energy to the multiple heating columns 73, and the heating columns 73 inside the connecting frame 72 will heat the cold water in the water heater body 1. When in use, open the water outlet valve 75 below to release the hot water for use. When the photovoltaic panel 54 generates electricity to heat the water in the water heater to a certain temperature, but no one uses the hot water, the controller 2 will start the motor 81, and the motor 81 will drive the rotating rod 82 to rotate. At this time, the rotating rod 82 will drive the valve plate 85 to rotate in the connecting chamber 84. At this time, the valve plate 85 is opened, and the heated water will flow into the heat preservation chamber 64 for storage. The sealing ring 86 is made of rubber material to block the inner wall of the connecting chamber 84 to prevent the hot water from leaking back into the water heater. Then the water in the water heater will be circulated and heated until someone uses it or it is cloudy and cannot absorb sunlight. When it is cloudy or the cold water is not heated to a certain temperature and needs to be used, the hot water stored in the heat preservation chamber 64 can be used for emergency use;
[0034] Then the insulation cover 55 is made of plastic and surrounds the outside of the connecting wire 71 to protect the connecting wire 71 from being damaged. The mounting base 51 can be screwed and installed on the roof or other places that can receive sunlight through the expansion bolts 52. Then the photovoltaic panel 54 is installed on the mounting base 51 to be fixed. The photovoltaic panel 54 will convert sunlight into electrical energy and transmit it to the heating column 73 for heating. Another part of the electrical energy will enter the storage battery 61 for storage.
[0035] Finally, the insulation chamber 64 has an insulating rock wool layer installed on the inner wall to reduce the dissipation and loss of heat. When the battery 61 is charged at night or when there is no sunlight, the battery 61 will supply power to the insulation plate 62 through the power supply line 62. The insulation plate 62 is made of a low-power electric heating wire plate, which is mainly used to keep the hot water stored in the insulation chamber 64 warm, so that the temperature will not drop too much during use. If hot water is needed but the water heater does not heat it up or the sun is in a cloudy state, the solenoid valve 9 can be opened at this time, and the preheated water pipe 65 will lead the hot water stored in the insulation chamber 64 for easy use. The quick heater 66 on the preheated water pipe 65 will be powered by an external power supply and will not use the power of the battery. The high-power quick heater 66 can also be powered normally and is not easily overloaded.
