Electric heating device for rapidly heating water to boiling and heating method thereof

Abstract

The invention discloses an electric heating device for rapidly heating water to boiling and a heating method thereof. The electric heating device comprises a water storage tank, a water pump and a heater, wherein the water storage tank is connected with the water pump which is connected with a water inlet of the heater; the water outlet of the heater is connected with a water outlet of the device; the heater is provided with a temperature detection unit; the lower end of the water outlet of the heater is connected with a reflow switch through a pipeline; the water outlet of the device is positioned between the reflow switch and the heater; and the reflow switch is connected with the water storage tank through a pipeline. By the control of the reflow switch, water is reflowed to the water storage tank when the water temperature cannot meet the boiling requirement and the water temperature of the water storage tank is raised after hot water reflows; and after the temperature is raised, the temperature of effluent heated by the heater is easier to boil. In addition, the temperature detection unit is arranged for monitoring the temperature of the effluent in real time, ensuring that the temperature of the effluent is consistent and increasing the judgment on the boiling so as to realize 100 percent of boiling of any district.

Description

technical field [0001] The invention relates to the field of electric heating, in particular to an electric heating device for rapidly heating water to boiling, and a heating method of the electric heating device. Background technique [0002] Current liquid heating equipment includes electric kettles, instant heaters and other equipment. For mechanically controlled electric kettles, which use steam temperature control, they can only be used in a specific area. When used under different air pressure conditions, due to water If the boiling point of the water is different, the requirement of complete boiling cannot be achieved. In addition, there are devices such as instant heating heaters in the market, which can heat water to a higher temperature in a short period of time, such as about 80 degrees. The working process is to pump cold water into the heater for heating. Therefore, cold water The difference in temperature will make the water temperature after heating differen...

Problems solved by technology

[0002]The current liquid heating equipment includes electric kettles, instant heaters and other equipment. For mechanically controlled electric kettles, which use steam temperature control, they can only be used for a certain In certain areas, when used under different air pressure conditions, due to the different boiling points of water, the requirement of complete boiling cannot be achieved

In addition, there are devices such as instant heating heaters in the market, which can heat water to a higher temperature in a short time, such as about 80 degrees, and its working process is to pump cold water into the heater for heating. Therefore, cold water The difference in temperature will make the water temperature after heating different, not only can not achieve 100% boiling, but also the difference in water temperature after heating is relatively large
