Method and apparatus for determining boiling point temperature, and electric pressure cooker

Abstract

The invention discloses a method and apparatus for determining a boiling point temperature, and an electric pressure cooker. The method comprises the following steps: acquiring a steam temperature in the electric pressure cooker; determining whether the steam temperature is greater than a first temperature threshold, and if so, controlling an electromagnetic exhaust value to be open; recording heating stay time of the steam temperature at each degree when the steam temperature rises; and determining whether the heating stay time of the steam temperature at Tx DEG C is greater than the total of the heating stay time consumed when the steam temperature rises from Tx-n DEG C to Tx-1 DEG C, and if so, determining that the Tx DEG C or Tx-m DEG C is the boiling point temperature, wherein n is greater and equal to two, and m is a temperature correction value. According to the method and apparatus for determining the boiling point temperature, and the electric pressure cooker, boiling points of regions with different altitudes can be determined, the problem of difficult cleaning caused to a product or a kitchen due to food spay when air is exhausted and pressure is released and the problem of incapability of opening a top cover after the air is exhausted and the pressure is released are avoided, safety hidden risks are reduced, and application comfortableness of users is improved.

Description

technical field [0001] The invention relates to the technical field of electric pressure cookers, in particular to a method and device for determining boiling point temperature, and an electric pressure cooker. Background technique [0002] Electric pressure cooker is an upgraded product of traditional pressure cooker and electric rice cooker. It combines the advantages of pressure cooker and electric rice cooker, can meet various cooking needs, and can realize various cooking methods quickly, safely and automatically. The principle of an electric pressure cooker is that the boiling point of water is directly proportional to the air pressure. As the air pressure increases, the boiling point of water will also increase accordingly. Under normal atmospheric pressure, if you use an ordinary pot to boil water, the boiling point will not exceed 100°C. Even if you continue to heat it, the temperature of the water will not exceed the boiling point. After the pressure steam is gene...

Problems solved by technology

Temperature-controlled electric pressure cooker is a kind of electric pressure cooker widely used. It releases pressure and exhausts air according to the temperature of the top temperature sensor. At altitude, the internal and external relative pressures of the electric pressure cooker are different. During the pressure relief and exhaust process, the food in the electric pressure cooker will be ejected under the action of the internal and external pressure difference. The food ejection is harmful to product cleaning and product safety. bring about bigger problems
