Problems solved by technology

Even if the user only uses a small amount of hot water, all the water stored in the water tank needs to be heated electrically, resulting in unnecessary waste of electric energy
At the same time, users have to wait for a long time for electric heating

Abstract

The invention discloses an instant heating type solar water heater, wherein the power consumption of the solar water heater is saved by the optimum heating means; the electronic compensating power consumption of the solar water heater is reduced to the lowest; the solar water heater approaches to heating of water stored in a water tank by fully depending on solar energy; and the solar water heater not only meets the requirement of random use of hot water but also does not cause unnecessary electric energy waste. The instant heating type solar water heater comprises the water tank and a heat accumulator, and also comprises an electrically heated instant heating device, wherein the electrically heated instant heating device can be arranged on a water outlet end in the water tank or be connected in series to any position of a pipe between an outlet on the outside of the water tank and a water terminal. The instant heating type solar water heater greatly reduces the power consumption cost and the time cost for users of all types of solar water heaters such as split-type solar water heaters, closed type solar water heaters, and open type solar water heaters. When the electrically heated instant heating device is arranged inside a solar water heater system, the solar water heater system has three functions of the solar water heater, a water storage type electric water heater and an instant heating type electric water heater.

Description

(1) Technical field [0001] The invention relates to the solar water heater manufacturing technology, and also relates to electric heating and its control technology. (2) Technical background [0002] Solar energy is recognized as the cleanest energy, and it has been widely used now. Solar water heaters have been accepted by more and more families. However, due to the influence of weather and seasons, its use effect is not satisfactory. In order to ensure normal use, the solar water heaters currently on the market are equipped with auxiliary electric heaters to compensate for the lack of solar energy. As disclosed in Chinese patent 02232915, when the heat collecting tube of the solar water heater heats the stored water insufficiently, the solar water heater will use an electric heater to raise the temperature of the stored water in the water tank to the water temperature required by the user. The disadvantage of this kind of electric supplementary heating of solar water he...
