Description

Storage instantaneous electric water heater structure

The present invention relates to an electric water heater; in particular, it relates to a storage instantaneous heat electric water heater structure capable of achieving the dual functions of preheating and instant heating.

According to the general electric water heater, please refer to Figure 1. It consists of a water storage tank 1 with a closed water storage area 10, a normal temperature water inlet pipe 12 connected to the water storage area 10 of the water storage tank 1, and a continuous Pass the water storage area 10 of the water storage cylinder 1 to the hot water pipe 13 at the outer side of the water storage cylinder 1, and a set of heating pipes 15 arranged at the water storage area 10 of the water storage cylinder 1. In this way, when the heating pipe 15 When heating is started, the cold water source distributed on the peripheral side of the heating tube 15 will directly absorb the heat energy generated by the heating tube 15 so that the temperature of the water source starts to increase. After the cold water source in the water area 10 reaches a predetermined temperature due to heating, the heating pipe 15 will stop operating.

Although the above creation can achieve its creation purpose, however, the following deficiencies will occur in the process of operation and use:

Because the conventional technology is in the heating process, the cold water source of the entire water storage area must be heated to a predetermined high temperature before stopping the operation of the heating tube. As a result, when the temperature during the waiting (ie waiting) period drops to When the lowest predetermined temperature is reached, the heating tube must be activated to start heating, and the temperature of the entire water storage area must be reheated to the predetermined temperature. The heating is stopped only after the high temperature, so that the capacity of each reheating is too large, and the time required for reheating is too long, which in turn causes the consumption of electric power as a major problem.

As mentioned above, since each reheating refers to the entire water storage area, especially when consumers are heating while using it, the heat generated by the heating tube and the expansion of thermal convection will often flow down due to the cold water source. It flows directly to the drain inlet 130 of the hot water pipe 13, so that the hot water source of the high temperature layer will be quickly neutralized and cooled by the cold water source introduced, so that the temperature of the water storage water source in the water storage area is quickly reduced to a predetermined temperature. Immediately start the heating pipe 15 to reheat, and the neutralized and cooled water source will be directly discharged from the drain inlet 130 of the hot water pipe 13 for consumers to use, so that the consumer’s body temperature feels that the temperature is not high enough or The phenomenon of warmth is another major problem.

Therefore, how to develop a technology that can effectively shorten the reheating time, reduce the loss of intangible heat energy, and improve the heating efficiency and environmental protection and energy saving is a technical issue that the industry needs to solve first.

The main content of the storage instantaneous electric water heater structure of the present invention is to provide a method that uses the heat collecting sleeve assembly to be arranged in the water storage area of the water storage cylinder, and the upper and lower circulation holes of the heat collecting sleeve are respectively connected to the water storage area.
