Disclosure of Invention

The utility model aims to provide a tubular multiple progressive heating, liquid flow through instant heating, high thermal efficiency, energy-conserving mobile liquid progressive electric heater.

The utility model discloses the technical scheme who takes is, this kind of mobile liquid formula electric heater that advances progressively, including three font steel pipe of falling U, the bottom of two risers of every font steel pipe of falling U seals to respectively insert from its open-top and establish an electric rod, the power cord of electric rod links to each other with the power, and two adjacent font steel pipes of falling U set up relatively, and first font steel pipe of falling U and one side of second font steel pipe bottom are by violently managing a intercommunication, and the opposite side is the disconnection form, and second font steel pipe of falling U and one side of third font steel pipe bottom are by violently managing two intercommunications, and the opposite side is the disconnection form, violently manages a and violently manage two crisscross settings, establishes both sides separately, and feed liquor pipe is established to the bottom of first font steel pipe of falling U, and liquid pipe is established to the bottom of third font steel pipe of falling.

Furthermore, a sleeve with a thread wire is arranged on the top openings of the two vertical pipes of each inverted U-shaped steel pipe, and an electric heating rod with a thread bolt is screwed in the sleeve.

Furthermore, the load circuit is provided with an earth leakage protection switch and an earth protection device, and the liquid inlet pipe and the liquid outlet pipe are provided with electricity-proof wall protection.

Owing to adopted above-mentioned technical scheme, so the utility model has the advantages of it is following: first one fall U font steel pipe and the second fall one side of U font steel pipe bottom by violently managing a intercommunication, the opposite side is the disconnection form, the second falls U font steel pipe and the third fall one side of U font steel pipe bottom by violently managing two intercommunications, the opposite side is the disconnection form, violently manage one and violently manage two crisscross settings, divide and establish both sides, so set up the one-way curvilinear formula structure that had both realized liquid passage, the route of being heated has been prolonged again, make the liquid of the electric heater of flowing through the intensive formula heating that advances of six times of six electric heat bars in the three U font steel pipe, the temperature promotes rapidly, cross instant heating promptly, the heating time has been shortened, the heat efficiency is improved, the electric energy has been saved. Secondly, the water heater has wide application, can heat water, and is used for boiler heating, bathing, vegetable washing and the like; can also heat soybean milk, milk and beverage, is used in catering industry such as canteens, restaurants and the like, and can also heat industrial heat-conducting oil. And thirdly, the power connection requirement on the user is low. For example, for heating a house with three hundred square meters, the existing electric boiler needs 30-35 kilowatts to be brought up, a user needs to install a special transformer, and a large amount of capital is spent for purchasing the special transformer; however, the utility model can be carried up only by 9 kilowatts without installing a special transformer, and the common household electricity can meet the requirement, thereby saving a large amount of capital. Fourthly, the structure is simple and compact, the manufacture is easy, and the installation and use cost is low. For example, three hundred square meters of house heating is calculated according to 10 hours of heating each day and 0.17 yuan of electricity per degree (the price of Xinjiang electricity is low), the electric charge needs to be paid for 9180 yuan during the six-month heating period by using the conventional electric boiler, and the electric heater only needs to pay 2754 yuan. Fifthly, the electric heating device can be used as core equipment of heating devices with different purposes, and components such as a circuit control board, an electric leakage protection device, an electricity-proof wall, a temperature controller, a time controller, a machine shell and the like are configured to be improved so as to meet the requirements of the heating devices with different purposes. Is safe and reliable.
