The electric pressure cooker has the incomparable advantages of other cooking utensils. It can meet various cooking needs, and can quickly, safely and automatically realize various cooking methods. Its energy-saving and nutritious characteristics are the direction pursued by modern people.

However, the inner container of the existing electric pressure cooker is a flat-bottomed inner container. The heating efficiency of the flat-bottomed inner container is not high, the heating is uneven, and the heating speed is slow. Therefore, it is easy to affect the cooking of food by the electric pressure cooker.

Utility model content:

The purpose of the utility model is to provide an electric pressure cooker with a round-bottom liner for the deficiencies of the prior art, which has a large heating area, high heating efficiency, fast heating speed and good cooking effect.

In order to achieve the above object, the utility model adopts the following technical solutions:

An electric pressure cooker with a round bottom inner pot, which includes a pot cover, an outer pot, an inner pot, and a heating plate, the pot cover is fastened with the outer pot, the inner pot is arranged in the outer pot, and the heating plate is arranged directly below the inner pot. The hole in the middle of the heating plate is provided with a temperature sensor, and the bottom of the liner is in contact with the temperature sensor. The bottom of the liner is arc-shaped, and the upper surface of the heating plate is arc-shaped. match.

It also includes a sealing ring, which is arranged on the edge of the pot lid.

It also includes an elastic structure, the elastic structure is arranged at the lower part of the outer pot, and the elastic structure is in elastic contact with the bottom of the heating plate.

It also includes a pressure switch, the pressure switch is arranged under the outer pot, and the bottom of the outer pot is in elastic contact with the pressure switch.

The middle of the bottom of the inner container protrudes inwards and is provided with a protrusion, the protrusion is arranged directly above the temperature sensor, and the protrusion cooperates with the temperature sensor.

The beneficial effects of the utility model are:

An electric pressure cooker with a round bottom inner pot, which includes a pot cover, an outer pot, an inner pot, and a heating plate, the pot cover is fastened with the outer pot, the inner pot is arranged in the outer pot, and the heating plate is arranged directly below the inner pot. The hole in the middle of the heating plate is provided with a temperature sensor, and the bottom of the liner is in contact with the temperature sensor. The bottom of the liner is arc-shaped, and the upper surface of the heating plate is arc-shaped. match.

The arc-shaped liner at the bottom and the arc-shaped heating plate on the upper surface increase the contact area between the upper surface of the heating plate and the bottom of the inner liner, the heating area increases, the heating efficiency is high, and the heating speed is fast. Cooks well.
