[0057] The first embodiment (see figure 1 and figure 2 ):

[0058] The air port 211 has an intake state and a closed state, and the preset position has a first preset position. When the air pressure indicator 22 is in the first preset position relative to the inner cover 21, the air pressure regulating device changes the flow direction of the air flow in the air port, even if the air port 211 switches from the intake state to the closed state.

[0059] The transmitting part 23 is a triggering part. When the air pressure indicating part 22 is at the first preset position relative to the inner cover 21, the triggering part is triggered by the air pressure indicating part 22 and generates a first switching signal. Switch to off state.

[0060] Specifically, the trigger is an inductive switch. When cooking, the air port 211 is in the intake state, and outside air enters the cooking space 30 through the air port 211, and the pressure in the cooking space 30 rises. When the pres...

[0066] Second embodiment (see image 3 and Figure 4 ):

[0067] The air port 211 has an intake state and a deflated state. The preset positions include a first preset position and a second preset position. When the air pressure indicator 22 is at the first preset position relative to the inner cover 21, the air pressure regulating device changes the air pressure inside the air port. The flow direction of the airflow, even if the air port 211 is switched from the air intake state to the deflated state, when the air pressure indicator 22 is at the second preset position relative to the inner cover 21, the air pressure regulating device changes the flow direction of the air flow in the air port, even if the air port 211 is switched from the deflated state Switch to intake state.

[0068] The transmission part 22 is an elastic conductive part. When the air pressure indicating part 22 is at the first preset position relative to the inner cover 21, the air pressure indicating par...

Abstract

The invention relates to a cover body and a cooking utensil, and the cover body comprises an inner cover and an air pressure indicating piece, wherein the inner cover is arranged above the cooking main body in the cooking utensil, a cooking space is defined between the inner cover and the cooking main body, and an air port communicating with the cooking space is formed in the inner cover in a penetrating way; the air pressure indicating piece is movably connected to the inner cover and can move relative to the inner cover under the action of pressure difference between the cooking space and atmospheric pressure; and wherein the cover body further comprises an air pressure adjusting device, and when the air pressure indicating piece is located at a preset position relative to the inner cover, the air pressure adjusting device changes the flow direction of air flow in the air port and controls the pressure in the cooking space to be within a preset pressure range. When the air pressure indicating piece is in the preset position relative to the inner cover and the pressure in the cooking space is too high or too low, the air pressure adjusting device changes the flow direction of theair flow in the air port, so that the pressure in the cooking space is within the preset pressure range to ensure effective control of the pressure in the cooking space.

Description

technical field [0001] The invention relates to the technical field of cooking utensils, in particular to a cover body and a cooking utensil having the same. Background technique [0002] With the development of society and the progress of science, people are more and more pursuing the quality of life. Cooking utensils such as electric rice cookers and electric frying pans are widely used in people's daily life and have become indispensable tools in people's lives. [0003] The electric rice cooker mainly includes a cooking body, a cover, and a control device. The cover is set on the cooking body and forms a cooking space with the cooking body. The control device controls the rice cooker to perform operation modes such as cooking and heat preservation. displayed on its display panel. [0004] Traditional rice cookers cannot effectively control the air pressure in the cooking space, which will lead to poor color, aroma and flavor of the cooked food. Contents of the inventi...
