Description

Technical field:

[0001] The utility model relates to a water storage type electric water heater, in particular to a dual-purpose electric water heater for storing and reserving water. Background technology:

[0002] Since electric water heaters became popular, most people have used storage-type water heaters. These primarily consist of an inner tank, electric heating tube, thermostat, water inlet pipe (inlet), water outlet pipe (outlet), drain outlet, and a pressure relief safety check valve. The outlet of the water inlet pipe (inlet) and the inlet of the drain outlet are located at the bottom of the inner tank; the inlet of the outlet pipe (outlet) is located at the top of the inner tank, slightly below the highest level of the stored water. The inlet pipe (inlet) is permanently connected to the tap water line. When in use, open the outlet valve (usually a mixing valve) on the outlet pipe (outlet), and the heated water in the inner tank flows out through the outlet pipe (outlet) under the pressure of the tap water. As the hot water flows out, tap water also flows into the inner tank, replenishing the stored water, and this cycle continues, providing a continuous supply.

[0003] According to the actual use and the contents of the "Instruction Manual" of the storage electric water heater provided by the water heater manufacturer, the water inlet pipe (water inlet), the inner tank, and the water outlet pipe (water outlet) are a closed system that is interconnected. Since the configured pressure relief safety one-way valve is a one-way valve, this closed system is always in a high-temperature, high-pressure state. As a result, when filling the water heater with water, the water outlet valve must be opened to remove the air in the inner tank. Since the water inlet on the water outlet pipe (water outlet) is located at the upper part of the inner tank, when water flows out When the water valve flows out, it indicates that the air in the inner tank has been basically exhausted and the water has been filled. Then close the water valve and turn on the power to heat it. When the tap water is cut off, even though the inner tank is full of water, due to the loss of the tap water pressure, no water will flow out even if the water valve is opened. Although it is called a "water storage" type, it does not actually have the function of "reserve" water. Turn off the tap water (equivalent to stopping the tap water), open the drain port, and drain the inner tank. If the relevant components are not disassembled, the drain port will not discharge "sewage", making the drainage operation very inconvenient. This is due to the closed system. These shortcomings bring inconvenience to use and are also technical problems. Summary of the invention:

[0004] The purpose of the utility model is to provide a dual-purpose electric water heater for storing and reserving water, which adds a function of storing and reserving water to the electric water heater, making it a dual-purpose device.
