Description

Fast heat storage type electric water heater

technical field

The utility model relates to an electric water heater, in particular to a fast-heating storage type electric water heater.

Background technique

Electric water heaters are more and more popular due to energy saving and pollution-free. With the continuous improvement of people's living standards, people's requirements for electric water heaters are also getting higher and higher. At present, the water storage type electric water heaters on the market, because they are water storage types, are limited by the capacity when using hot water, that is, the small capacity water storage type electric water heaters cannot store enough hot water to meet the needs of people for bathing. , and the large-capacity storage-type electric water heater takes up space, and the cost of consumables is high. Moreover, the heating time of the storage-type electric water heater is relatively long, and easy scaling is the defect of the existing storage-type electric water heater; The high power and unstable circuit of the electric water heater are the defects of its existence. In order to make the water storage type electric water heater also achieve fast results, some people have invented a new way of combining instant heating and water storage, such as the patent application for the patent application number 02149630.7, which is called the environmental protection instant heat storage type electric water heater , which includes a water storage tank, a water inlet pipe, a water outlet pipe, a heater, a thermostat for controlling/regulating water temperature, an over-temperature circuit breaker and a temperature/pressure discharge valve for ensuring the safe use of the water heater, and is characterized in that said A radiant heat collector, a radiant heat absorbing pipe, a direct hot water injection conduit, a direct hot water injection nozzle, and a universal multi-purpose joint are installed at the bottom of the water storage tank. This product enables the water storage to be supplied with electricity and hot water. After the water storage is preheated, the hot water consumption will be more than double that of traditional water heaters. However, the water heater of the above-mentioned patent has the disadvantages of large volume, complicated structure and high production cost, and its hot water consumption is still limited.

Utility model content

The purpose of the utility model is to solve the deficiencies of the prior art, and provide a water storage type electric water heater which is not only simple in structure, but also environmentally friendly and energy-saving.

The utility model adopts the following technical solutions to achieve the above object:

The fast heat storage type electric water heater mainly includes an electric water heater body with an inner tank, a water inlet pipeline connected to the electric water heater body, a hot water outlet pipeline, a water flow sensor and a controller, and a secondary electric heater is installed in the inner tank , is characterized in that: a main electric heater is arranged in the hot water outlet pipeline.

As a further description of the above solution, the hot water outlet pipeline includes the hot water outlet pipe inside the inner tank and the hot water outlet pipe outside the inner tank, and the main electric heater is set in the hot water outlet pipe inside the inner tank Or be arranged in the outlet hot water pipe outside the liner.

The water inlet end of the hot water outlet pipe inside the inner container is arranged on the upper part of the inner container.

Sealing gaskets are arranged between the hot water outlet pipeline and the inner tank, and between the main electric heater and the inner tank.

The water flow sensor is arranged on the hot water outlet pipeline and connected with the controller.

The secondary electric heater is arranged on the inner tank flange.

The hot water outlet pipeline is copper, alloy steel or engineering plastic pipe.

The beneficial effect that the utility model can reach by adopting above-mentioned technical solution is:

1. The fast-heating water storage electric water heater of the utility model is equipped with a main electric heater on the hot water outlet pipeline, and a secondary electric heater is set on the inner tank flange. When the water storage electric water heater enters the working state, the secondary electric heater The heater heats the water in the inner tank to the heat preservation state and then disconnects the power supply. If you need to shower or wash with hot water (that is, when water flows out of the hot water pipeline), the water flow sensor will send out a signal, and the controller will control the main electric heating. The heater is connected to the power supply, and the hot water flowing out is reheated directly, so as to achieve the purpose of heating the water quickly. At the same time, the power supply of the secondary electric heater is cut off. When the hot water is stopped, the power supply of the main electric heater is immediately disconnected. , if the inner tank water temperature is lower than the set temperature, the secondary electric heater will automatically continue to heat the water in the inner tank to the heat preservation state. In this way, the hot water output rate of the water storage type electric water heater can be greatly improved, which not only meets people's requirements for using hot water, but also achieves the purpose of saving energy and reducing consumption.

2. The utility model has a simple structure, and since the water outlet pipeline can be provided with an inner tank, the volume can be greatly reduced, and the heating efficiency can be improved at the same time, and the production cost is low.
