Description

energy-saving electric heating pot

technical field

The utility model belongs to the improvement of an electric heating pot, in particular to a power-saving electric heating pot.

Background technique

Electric rice cooker, electric rice cooker and electric heating stove etc. are all indispensable cooking utensils in people's daily life, but although the electric rice cooker and electric cooker etc. used in our country have the function of heat preservation after the rice is cooked, when the temperature in the pot is high When it is at or below the set temperature value, the sensitivity of the sensor is not high, the response time lags and is too long, and the cycle of power on and off is long, which wastes excess electric energy, so a considerable part of this kind of rice cooker and rice cooker Electric energy and time are consumed on heat preservation, resulting in relatively poor energy saving and time-consuming.

Contents of the invention

The purpose of the utility model is to provide a power-saving electric heating pot, which has high sensitivity, fast response time, time saving and high power saving and energy saving performance.

The utility model is realized in the following way: a power-saving electric heating pot, comprising a pot cover placed on the opening of the pot body and a heating device for heating the pot body, a through hole is opened on the pot cover, and the lower opening of the through hole It communicates with the inner cavity of the pot body, and its upper opening communicates with the atmosphere. A temperature controller is arranged above the through hole. The temperature contact of the temperature controller faces the through hole. The temperature controller is connected in series with the heating device on the power supply circuit through wires. .

Because the temperature controller used in the utility model is arranged above the through hole on the pot cover, the temperature contact of the temperature controller faces down and faces the through hole opened upwards, and the heating device heats the cooked food in the pot until the high-temperature water vapor It is ejected from the through hole on the pot cover, and the ejected high-temperature water vapor is sprayed onto the temperature contact of the temperature controller. The temperature of the water vapor sensed by the temperature controller is higher than its own set value. At this time The temperature controller starts to work, and automatically cuts off the circuit, so that the heating device stops heating up; when the temperature in the pot decreases due to heat loss, the temperature sensed by the temperature controller is lower than the heat preservation value set by the temperature controller, and the temperature controller then The circuit is automatically connected, so that the heating device is energized to heat up to the set heat preservation value. If the temperature sensed by the temperature controller is higher than the set heat preservation value again, the above-mentioned heat preservation work of automatic power-on and power-off will be carried out again, and the cycle work will be performed. The utility model uses a temperature controller arranged above the through hole of the pot cover to sense the temperature of the water vapor sprayed from the pot, and the water vapor in the pot will pass through the pot cover due to the increase in temperature and pressure. The through hole escapes and ejects quickly, so the time it takes for water vapor to spray from the pot to the temperature contact of the temperature controller through the through hole is very short, which shortens the time for reaction. In addition, the heat-resistant pad clamped between the bracket and the surface of the pot lid can further prevent the thermal energy of the high-temperature water vapor that is not ejected from the pot from being transmitted to the contacts of the temperature controller through the bracket because of its poor thermal conductivity. The sensitivity of the temperature controller and prevent it from prolonging the response time. The heat-resistant pad is especially suitable for installation on the surface of the pot cover made of metal materials. The heating device used can be electric rice cooker and electric rice cooker (electric heating plate, electric heating wire) , Induction cooker (electromagnetic eddy current coil), etc. Through experiments and use of the utility model, the power-saving rate per hour reaches 50.29%-77.96%, and the power supply is immediately connected within 6 seconds after the pot cover is opened. The electric heating pot with a power of 900W (the water boiling time is 11 minutes, the power-off time is 138s, and the power-on time is 9s) is energized to heat and keep the food warm. The power saving efficiency of the electric heating pot for 2 hours can reach 85.3%. The utility model has the advantages of high sensitivity, fast response time, time saving and high power saving and energy saving performance.
