Method and device for determining boiling points of water under different altitudes as well as electric pressure cooker

Abstract

The invention provides a method and device for determining boiling points of water under different altitudes as well as an electric pressure cooker. The method comprises the following steps: under the current altitude, computing the time when the temperature is increased by 1 DEG C for each time in the process that water is heated to a second temperature value from a first temperature value; and determining the boiling point of the water under the current altitude according to the change rule of the time when the temperature is increased by 1 DEG C for each time in the process the water is heated to the second temperature value from the first temperature value. By adopting the technical scheme, the fact that the boiling points of water under different altitudes can be conveniently, rapidly and effectively determined is realized, so that the internal relative pressure of the electric pressure cooker can be flexibly and conveniently adjusted to be in a safety range under different altitudes.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to a method and device for determining the boiling point of water at different altitudes, and an electric pressure cooker. Background technique [0002] Since the current electric pressure cooker relies on the top probe to sense the temperature and then control the internal relative pressure, for example, as shown in Table 1 below, at the boiling point temperature, for every 1°C increase, the pressure will increase by 5KPa. Such as figure 1 As shown, in high altitude areas, the boiling point decreases, and after the boiling point decreases, if the internal relative pressure is not adjusted, the system still controls the pressure according to the boiling point of 100°C, which will cause the internal relative pressure to be too high, and the normal pressure relief operation will be squirt.

AI Technical Summary

Problems solved by technology

[0005] For the above situation, the prior art proposes an electric pressure cooker with a pressure detection device, which identifies the altitude through the pressure value detected by the pressure detection device, determines the boiling point of water at this altitude, and then controls the relative pressure inside the electric pressure cooker according to the boiling point of water. pressure, but this kind of electric pressure cooker requires a special zero pressure detection device, and the electric pressure cooker without a zero pressure detection device cannot effectively control the internal relative pressure
