Water heater capable of switching heat sources automatically

Abstract

The invention discloses a water heater for automatically switching heat sources, comprising: a solar water heater; a gas water heater, one end of which is provided with a water inlet, and one end is provided with a water outlet; a first solenoid valve, which is arranged on the first pipeline; a second solenoid valve, which It is arranged on the second pipeline; the third electromagnetic valve is arranged on the third pipeline; the fourth electromagnetic valve is arranged on the fourth pipeline; the temperature sensor is arranged in the solar water heater a water level sensor, which is arranged in the solar water heater; a timer, which is arranged in a controller; a controller, which is connected with the first solenoid valve, the second solenoid valve, the third solenoid valve, the fourth solenoid valve, Temperature sensor, water level sensor and timer connection. The present invention maximizes the advantages of renewable energy, while ensuring the advantages of gas water heaters, realizing complementary advantages, instant heating when turned on, and finally achieving multiple effects such as energy optimization, convenient operation and use, and reduced economic expenditure for users.

Description

technical field [0001] The invention relates to a water heater, in particular to a water heater for automatically switching heat sources. Background technique [0002] At present, there are several major problems in solar water heaters: 1) they cannot meet the requirements of all-weather use, such as not being able to be used in winter, and the water is not hot when the light is not good, etc., and the ability to provide hot water for 24 hours cannot be realized; 2) waiting for use and wasting water. With the gradual popularization of solar water heaters, people have higher and higher practical requirements for solar water heaters. Solar water heaters, gas water heaters, and electric water heaters are relatively common multi-energy water heaters on the market, each with its own advantages and disadvantages. Solar water heaters are energy-saving products. , combined with electric water heaters and gas water heaters, and multi-energy complementarity is the current market devel...

Problems solved by technology

[0002] At present, there are several major problems in solar water heaters: 1) It cannot meet the requirements of all-weather use, such as it cannot be used in winter, the water is not hot when the light is not good, etc., and it cannot realize the guarantee of providing hot water for 24 hours; 2) Waiting for use and wasting water

At present, a solar water heater is combined with an electric water heater or a gas water heater by means of a controllable circuit to realize automatic switching between the two water heaters, but the switching control module is not organically combined with the solar control system, and the user needs to operate it when using it. 2 to 3 control systems, very cumbersome and poor applicability
