In a specific embodiment, as shown in fig. 2-3 and 5, the clamping protrusion 524 is disposed on the periphery of the moving portion 523, the clamping groove 525 is disposed on the sealing portion 522, and the sealing portion 522 is sleeved on the periphery of the moving portion 523 and clamped with the moving portion 523. Of course, the clamping protrusion 524 may also be disposed on the sealing portion 522, and the moving portion 523 is disposed with the corresponding clamping groove 525, which is not limited in this embodiment.

As a preferred embodiment of the present invention, as shown in fig. 2 to 5, the pressure relief assembly 5 further includes an elastic restoring member 6, and the elastic restoring member 6 is configured to apply a force to the moving member 52 in a direction away from the cooking cavity 111, so as to move the sealing portion 522 to a position for closing the air inlet channel 31.

When the sealing portion 522 moves from the position closing the air inlet channel 31 to the position opening the air inlet channel 31, the elastic resetting piece 6 is extruded to be elastically deformed, so that a force deviating from the direction of the cooking cavity 111 is applied to the moving piece 52, when the user stops operating the control piece 51, the elastic resetting piece 6 pushes the sealing portion 522 to be reset, the air inlet channel 31 is closed again, the air inlet channel 31 is kept in a normally closed state, and the normal operation of the cooking process is facilitated.

Specifically, as shown in fig. 2 to 5, when the moving member 52 and the sealing portion 522 move downward to open the air inlet channel 31, the moving member 52 presses the elastic restoring member 6 to deform, and applies an upward force to the moving member 52, so as to drive the moving member 52 and the sealing portion 522 to move upward to restore to the position of closing the air inlet channel 31.

The cooking process of the cooking appliance of the present invention will be described in detail below, taking steamed rice as an example. However, it should be noted that the cooking appliance is not limited to cooking rice, but may be used for cooking other food, such as steamed bread, steamed stuffed bun, etc., and is not limited in this respect.

In one embodiment, before cooking begins, the user places rice on the steaming rack 8 in the cooking chamber 111 and adds a sufficient amount of water to the water storage chamber 121. Preferably, the water storage chamber 121 is provided with a water level line to prompt a user to add water for cooking.

After cooking begins, in the stage of heating and absorbing water, heating device 2 starts, to the water heating in the water storage chamber 121 is to first predetermined temperature (such as 30 ℃ -60 ℃), at this moment vacuum pump 4 starts, will cook the air escape in the chamber 111, make cook chamber 111 and be in the negative pressure state, at this moment partial water in the water storage chamber 121 flows from the water storage chamber 121 under the effect of atmospheric pressure difference to cook in the chamber 111, to the rice in the cooking chamber 111 soaks, and the even entering grain of rice of moisture makes its abundant absorption, has avoided rice to appear the phenomenon of half-cooked or upper and lower soft and hard inhomogeneous.

Preferably, in the above stage, the rice is soaked in water for 10min-40min to make the rice fully absorb water, and make the water content of the rice reach 30% -55%, so as to obtain good taste.

In the draining stage, the vacuum pump 4 stops working, because the heating device 2 heats water to generate steam, the steam flows from the water storage cavity 121 to the cooking cavity 111, so the air pressure difference between the two is gradually reduced until the air pressure between the two is basically balanced, or the pressure relief assembly 5 can be opened to enable outside air to enter the cooking cavity 111, so that the air pressure in the cooking cavity and the water storage cavity 121 is balanced, and at the moment, the water in the cooking cavity 111 flows back to the water storage cavity 121 under the action of self gravity to be separated from rice.

In the pre-gelatinization stage, after the water in the water storage cavity 121 is heated to a second preset temperature (such as 90 ℃ -98 ℃) by the heating device 2, the vacuum pump 4 is started again, so that the cooking cavity 111 is in a negative pressure state, at the moment, part of the water in the water storage cavity 121 flows into the cooking cavity 111 again under the action of air pressure difference, the rice in the cooking cavity 111 is soaked, and the surface of the rice is gelatinized due to higher water temperature to form a starch film, so that the rate of continuous water absorption of the rice grains is reduced, and the rice obtains certain hardness, namely has certain soft and hard mouthfeel.

Preferably, in the process, the soaking time of the rice in the water is 1min-15min, and the user can select the soaking time of the rice at the stage according to personal preference so as to obtain the rice with different soft and hard mouthfeel (the longer the soaking time, the more wet and soft the mouthfeel of the rice), so that the requirements of different users are met, and the user experience is improved.

In the steam cooking stage, the vacuum pump 4 stops working, steam flows from the water storage cavity 121 to the cooking cavity 111, so that the air pressure difference between the two is gradually reduced until the air pressure between the two is basically balanced, or the pressure relief assembly 5 can be opened to enable outside air to enter the cooking cavity 111, so that the air pressure in the cooking cavity and the water storage cavity 121 is balanced, and at the moment, water in the cooking cavity 111 flows back to the water storage cavity 121 under the action of self gravity to be separated from rice. The heating device 2 boils the water in the water storage cavity 121, and the rice in the cooking cavity 111 is steamed by using the steam until the rice is cooked.

Of course, the cooking device of the present invention is not limited to the rice cooking manner in the above embodiments, and other cooking manners may be adopted, such as increasing or decreasing the number of times the rice is soaked in water, and the like, and is not limited in detail herein.

The method can be realized by adopting or referring to the prior art in places which are not described in the utility model.
