A kind of electric pressure cooker with air extraction and air extraction control method

Abstract

The invention relates to the technical field of electric pressure cooker, and discloses an electric pressure cooker with air extraction, comprising a pot body, an outer pot, an inner pot, a pot cover, a control circuit, and operation buttons, wherein the outer pot is supported in the pot body, and the pot cover includes an outer Cover and inner cover, the inner cover is placed in the outer cover, the outer cover is rotated and buckled on the outer pot, and the inner cover is buckled on the inner pot; between the inner cover and the inner pot, there is a seal between the inner pot and the inner pot when the pot is in a negative pressure state. The sealing ring of the inner cover, the pot body is equipped with an air extraction device for extracting the gas in the inner pot, the inner cover is provided with an internal temperature detection device for detecting the temperature of the gas in the inner pot, and the pot body is provided with an external temperature detection device for detecting the temperature of the external environment. Temperature detection device. In the present invention, when there is remaining food in the pot that needs to be kept fresh, the air extraction device is activated to extract the residual air in the pot, and the sealing ring makes the inside of the pot in a sealed state, so that the outside air cannot enter, so as to achieve the purpose of keeping the remaining food fresh for a long time without the need for the user to The remaining food is poured out and kept fresh, which greatly facilitates the use of users.

Description

technical field [0001] The invention relates to the technical field of electric pressure cooker, and more particularly relates to an electric pressure cooker with air extraction and an air extraction control method. Background technique [0002] The electric pressure cooker is heated by an electric heating plate, the heating method is efficient and energy-saving, and the operation is safe and reliable. From the market performance point of view, it has gradually replaced the traditional pressure cooker. Electric pressure cooker is an upgraded product of the optimized combination of traditional pressure cooker and electric rice cooker. It combines the advantages of pressure cooker and electric rice cooker. It uses electric energy for heating in a sealed state inside the pot. It is environmentally friendly, convenient and fast, and can satisfy many It can meet the cooking needs in various aspects, and realize automatic cooking in multiple modes through the intelligent control ...

AI Technical Summary

Problems solved by technology

[0003] With the enrichment of people's material conditions, sometimes users use electric pressure cookers to cook more food, and there are often some food left in the pot after eating. Throwing away these foods will feel a bit wasteful. If they are kept in the pot, due to the residual oxygen in the pot , and the pressure inside and outside the pot is basically balanced so that the sealing ring cannot be completely sealed, and the air can circulate freely. fresh preservation

Both methods of preservation require pouring out the food, and then pouring the food into the pot for reheating when eating again, especially cold storage requires more energy to reheat the food, which brings inconvenience to users
