Description of the invention: [Technical field of invention] The present invention relates to a composite electric water heater, in particular to a composite electric water heater which is pre-stored with warm water slightly higher than normal temperature and can be heated instantaneously when taken. design. [Prior Art] The conventional electric water heater is mainly divided into two types: a storage type electric water heater and a instant type electric water heater. The storage type electric water heater is provided with a water storage tank in the main body, and a certain amount of water is pre-stored in the water storage tank and heated to a rated temperature (usually between 55 ° C and 65 ° C), when the user opens the faucet The hot water is mixed with cold water through a hot water pipe, and the water is used at an appropriate temperature. The instant electric water heater constitutes a smaller heating device, which is usually directly installed in the bathroom and connected to the hot water pipe, and is heated by the user when the faucet is turned on. Although the two kinds of electric water heaters are safer than the traditional gas water heaters, there are some missing situations. For example, storage electric water heaters often keep the water temperature between 55 °C and 65 °C, which will be caused by heat balance. The water temperature drops, so even if the hot water is not used, the electric energy will be consumed by the automatic heating and heating of the cooling, and the outer layer of the water storage tank needs to design a plurality of heat-insulating materials for preventing heat loss, which not only makes the purchase cost too large, but also the monthly electricity cost is quite amazing. Others, such as many people use, the amount of hot water is insufficient, waiting for the water to heat up for a long time, and the internal electric heating tube is easy to accumulate scale, resulting in short life and low thermal efficiency. For example, a hot electric water heater, although it does not need to consume electricity to maintain the water temperature, when the faucet is turned on, a considerable amount of electricity is required to enter the 200825343 line for instant heating, and the amount of hot water is also small. It can be seen that how to save energy, save time and be practical, that is, the technical bottleneck that the electric water heater needs to overcome 0 [Summary] The main object of the present invention is to provide a composite electric water heater, by the composite electric water heater The internal equipment is constructed and designed to have the function of water storage cycle heating and instant instantaneous heating. It can automatically warm the storage tank cold water to a temperature slightly higher than normal temperature during normal times. This design can shorten the waiting time of users. And the heat dissipation phenomenon due to heat balance, reducing the frequency of automatic heating and heat preservation due to cooling, so as to reduce power consumption; and when actually using warm water, avoid using excessive power to instantly heat the pre-stored warm water. Thereby, the user is saved in time and power saving and practical effects. According to the above objective, the implementation of the present invention mainly comprises a base, a water storage tank, a water pump, a heating device and a first-class control device.

The flow control device comprises a three-way valve, wherein the first valve port is connected with the hot water outlet pipe, and the second valve port is connected. There is a pressure switch for controlling the supply of hot water to the faucet, and a third valve port is connected with a normally closed electromagnetic valve to control the return of warm water to the water storage tank; by the above-mentioned construction and assembly design of each device, 200825343 constitutes the composite electric water heater of the present invention.
