[0036] like Figure 1-2 As shown, the embodiment of the utility model provides a solar energy storage type electric water heater, comprising:

[0037] Mains electricity;

[0038] Solar energy storage system, which is used to convert solar energy into electrical energy;

[0039] Also includes:

[0040] A storage battery 3, which is used to charge and store energy in off-peak hours or by utilizing solar energy, so as to provide electric energy to the heating element 11 when needed;

[0045] A first switch, electrically connected to the water pump 14, for starting or stopping the water pump 14;

[0046] A second switch is electrically connected to the storage battery 3 and is used to charge the storage battery 3 in the valley section;

[0047] The battery 3 and the mains 4 are connected in parallel;

[0048] Terminology explanation: Peak and valley electricity time periods are usually divided into peak and valley periods. Peak periods are periods of high electricity demand, while valley periods are periods of low electricity demand. Depending on different regions and electricity policies, the specific times of peak and valley may vary. The following are some common peak and valley electricity time period divisions:

[0049] Peak hours: 8:00-22:00 or 11:00-19:00, the specific time may vary by region.

[0050] Valley period: 22:00-8:00 the next day or 11:00 pm to 7:00 am the next day, this is the period with the lowest electricity demand.

[0051] The peak and valley time periods in individual regions may vary, and it is recommended to check according to the electricity policies of specific regions. In addition, the implementation of peak and valley electricity prices is intended to encourage users to use electricity during periods of low electricity demand and use electricity resources in a more economical way.

[0052] During the off-peak period, the storage battery 3 is charged to increase the amount of hot water, relax the electricity consumption environment, store the low-priced electricity at night, and store the electricity of solar energy. In spring, summer and autumn, the stored electricity is used first for hot water, and in winter it can be used in parallel with ordinary electricity, which can increase the hot water output, improve the mains electricity consumption, and reduce the power line environment.

[0058] In this embodiment, specifically: the water inlets of the two heating chambers 1 are connected to the water outlet of the water pump 14 through the second water pipe 15;

[0059] The water outlets of the two heating chambers 1 are both connected to the spraying device 13 through the first water pipe 12;

[0060] The water pump 14 delivers water into the heating chamber 1, and the water is heated by the heating body 11;

[0061] The first water pipe 12 and the second water pipe 15 are also provided with electromagnetic valves for determining whether the first water pipe 12 and the second water pipe 15 are unblocked;

[0062] When using water, the solenoid valve on the first water pipe 12 is opened, and the water source is sprayed out through the spraying device 13. The spraying device can be a shower head and can be freely set according to the needs of the user.

[0063] When the utility model is working, it can charge the storage battery 3 during off-peak periods, or use the solar energy electric shock system to transmit the electric energy that exceeds the actual demand to the storage battery 3 to store the electric energy, thereby increasing the amount of hot water, relaxing the electricity usage environment, and storing the low-priced electricity at night. It can also store the electricity of solar energy, and use the stored electric energy first when using hot water in spring, summer and autumn. It can also be used in parallel with ordinary electricity in winter, which can not only increase the hot water output, but also improve the mains electricity consumption and reduce the line environment.

Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
