[0003] At present, the scale of my country's solar energy industry has ranked first in the world, and it is the country with the largest production and use of solar water heaters in the world. However, solar water heaters are too dependent on sunlight, and the water temperature will drop in continuous cloudy days or excessive use of hot water. , can not reach the temperature required for bathing, causing inconvenience to users
The solar water heater with electric auxiliary heating completely consumes electric energy when auxiliary heating is required, which is not conducive to saving high-grade energy

Embodiment Construction
[0013] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the following describes the specific implementation of the solar water heater of the present invention with reference to the accompanying drawings.
[0014] figure 1 It is a schematic diagram of the structure of the solar water heater in the embodiment of the present invention.
[0015] Such as figure 1 As shown, the water heater 100 is used to heat cold water, and includes a solar unit 110, a heat pump unit 120, and a control unit 130.
[0016] The solar energy unit 110 is used to heat the cold water entering from the cold water pipe, and the solar energy unit 110 includes a solar energy unit 111 and a first temperature sensing unit 112.
[0017] The solar unit 111 is used to heat cold water to form warm water. The water inlet of the solar unit 111 is connected to a cold water pipe, and the cold water entering the solar device from the cold water pipe i...

Disclosed is a heater. Warm water is obtained by heating cool water through a solar energy portion, hot water is obtained by heating the warm water through a heat pump portion, and a control portion can control the heat pump portion to start and stop. The control portion controls the heat pump portion to start when the solar energy portion cannot heat the water into preset temperature, the warm water form the solar energy portion is heated, and problems that water temperature of the solar heater is lowered due to continuous cloudy days or too much water used and bathing of users cannot be met are solved; the heater adopt a combination of solar energy and a heat pump technology, the solar energy belongs to renewable green energy, a heat pump consumes a small part of power energy during operation, energy equivalent to 4-7 times of that of the consumed power energy can be extracted from environment media (water, air, soil and the like), and a great deal of high-grade energy sources can be saved.
Description
Technical field [0001] The invention belongs to the field of water heaters, and particularly relates to a water heater that heats cold water to form hot water. Background technique [0002] Under the dual pressure of energy crisis and environmental pollution, solar energy as a renewable green energy source has aroused widespread attention. The country has made accelerating the promotion and application of solar thermal utilization technology as the development focus of the new energy industry. [0003] At present, the scale of my country’s solar energy industry has ranked first in the world, and it is the country with the largest production and use of solar water heaters in the world. However, solar water heaters rely too much on sunlight, and the water temperature will drop on cloudy days or use too much hot water. , Can not reach the temperature required for bathing, causing inconvenience to users. However, the solar water heater with electric auxiliary heating completely consume...
