Instantaneous-heating type electric heater with heat energy secondary recycling

Abstract

The invention discloses an instantaneous-heating type electric heater with heat energy secondary recycling. The instantaneous-heating type electric heater with heat energy secondary recycling comprises a cylindrical water-electricity integrated electric heater, a heat energy secondary recycling spiral coil pipe, a secondary heat recycling water inlet electromagnetic valve, a pressure temperature controlling switch, a check valve, a secondary recycling water inlet tee-junction, a water inlet electromagnetic valve, an electromagnetic valve controller, a water inlet tee-junction, a pressure detecting controller and a computer controller, wherein the cylindrical water-electricity integrated electric heater is formed by mains supply L pole, a mains supply N pole, a cold water inlet, a hot water outlet, a spiral coil pipe inside a casting body and an electric heating pipe in a casting mode. One end of the spiral pipe inside the casting body is a hot water outlet and the other end of the spiral pipe inside the casting body is a cold water inlet. The spiral pipe inside the casting body is connected with a water pipe of a water dispenser or a gas water heater to form a water heating system in a matched mode. The spiral pipe inside the casting is a water pipe of the water-electricity integrated electric heater, and is connected with a water pipe of the spiral pipe inside the casting body to form a water secondary recycling reheating system after forming a waste heat reusing and recycling device with the heat energy recycling spiral pipe,.

Description

Technical field: [0001] The invention relates to an electric heater, in particular to a fast-heating electric heater with secondary heat recycling. Background technique: [0002] Water appliances such as water dispensers and electric showers on the market are all heated by water storage electric heaters. The water storage electric heater adopts the structure of "electric heater + water storage container", which has many defects, such as power consumption, low energy efficiency ratio, inconvenient use and so on. When the water storage type electric heater is used in a water dispenser, it will also cause the water to be heated repeatedly in the beaker, making it a phenomenon commonly known as "thousand boiling water", which does not meet the requirements of healthy drinking. When the water storage type electric heater is used in a shower, it will also cause problems such as high processing requirements, long heating time, inconvenient use, repeated heating for heat preservati...

AI Technical Summary

Problems solved by technology

[0004] In order to overcome the shortcomings of the existing water appliances such as water dispensers and water storage electric showers, using "water storage container + electric heater" for heating, the present invention provides a fast heat energy secondary recirculation The thermal electric heater can effectively solve the "thousand boiling water" of the water dispenser, and the "water storage electric shower" is a pressure vessel, which has high production and processing requirements, inconvenient use, and the use of water storage heating methods. Disadvantages of water leakage and high power consumption

It will be able to effectively solve the problems of existing electric heaters such as power consumption, low energy efficiency ratio, and inconvenient use
