In addition, the cooking mode of separating rice from water can also be used for preparing low-sugar rice. For example, the rice is soaked in water, starch, sugar and the like in the rice are dissolved in the water, and the rice is separated from the water in the subsequent steaming process, so that the sugar content of the cooked rice is reduced, the requirement of part of users for eating low-sugar rice is met, and the user experience is further improved.

It should be noted that the fluid medium in the first fluid channel 21 is not limited in particular, and in a specific embodiment, as shown in fig. 2, the pot body 1 is further provided with a vacuum pump 5, and the first fluid channel 21 is communicated with the vacuum pump 5 and the cooking cavity 111. When the cooking utensil works, the vacuum pump 5 starts to work, will air in the cooking cavity 111 is taken out, so that vacuum environment is realized in the cooking cavity 111, or water in the water storage cavity 121 is in the water storage cavity 121 with gush up to under the effect of the difference in air pressure in the cooking cavity 111, soak food.

Of course, the medium in the first fluid channel 21 may also be other fluids, such as steam, and the steam is delivered into the cooking cavity 111 through the first fluid channel 21 to achieve steam cooking, which is not limited in this respect.

Preferably, the cooking appliance further has a normal pressure state in which the air pressure in the water storage chamber 121 is substantially balanced with the air pressure in the cooking chamber 111.

When cooking, liquid (such as water and the like) is contained in the water storage cavity 121, food is placed in the cooking cavity 111, and when the vacuum pump 5 works to enable the cooking appliance to be in the negative pressure state, water in the water storage cavity 121 flows from an area with higher air pressure to an area with lower air pressure under the action of two air pressure differences, namely flows from the water storage cavity 121 to the cooking cavity 111, so that the food in the cooking cavity 111 is soaked.

After soaking for a certain time, the cooking appliance recovers to the normal pressure state, water in the cooking cavity 111 flows back to the water storage cavity 121 under the action of self gravity, is separated from food in the cooking cavity 111, and then is cooked by using steam generated by heating liquid in the water storage cavity 121. Use steamed rice as an example, water makes the rice grain fully soften after fully soaking the rice grain, utilizes steam heating rice grain again with the separation of rice grain, makes being heated of rice grain more even, and the culinary art taste is better, and the user need not to add the water yield according to strict rice water proportional control, can obtain the rice of different soft and hard tastes through control soaking time, has reduced the operation degree of difficulty, has improved and has used experience.

During the process of soaking the rice grains, the starch on the surface of the rice grains is dissolved in water and is separated from the rice grains during the cooking process, so that the cooked rice has less sugar content, and the requirement of a user for making low-sugar rice is met.

The fluid cover 2 is fixed on the pot body 1 in a gluing or welding mode, holes do not need to be formed in the surface of the fluid cover 2, the wrapping performance of the fluid cover 2 on the first fluid channel 21 in the fluid cover is improved, and the sealing effect of the first fluid channel 21 is further ensured. And no extra sealing element is needed, so that the sealing cost is reduced.

For the cooking utensil that the pot body 1 is visual, the gluey or welded connected mode need not to set up complicated connection structure, and the assembly is accomplished the back, only fluid cover 2 with form the one deck articulamentum between the pot body 1, and this articulamentum quilt fluid cover 2 covers, has consequently avoided the exposed appearance defect of connecting piece, makes cooking utensil is more pleasing to the eye.

In a preferred embodiment, the first connection position and the second connection position are fixed by ultrasonic welding. The welding speed is improved, the assembling time is saved, the welding strength is high, the sealing performance is good, and the sealing performance of the first fluid channel 21 is guaranteed. Compared with the traditional welding mode, the welding mode reduces pollution caused by welding and cannot damage the pot body 1 or the fluid cover 2.

In a preferred embodiment, at least a partial region of the pan body 1 is a structure made of a transparent material, and the projection of the fluid enclosure 2 towards the pan body 1 covers the projection of the first connection position and the second connection position towards the pan body 1.

Work as fluid cover 2 with 1 assembly of the pot body is accomplished the back, fluid cover 2 is right first connection position with the second connection position forms and shelters from, is used for unable direct-view first connection position with the second connection position has improved cooking utensil's whole is pleasing to the eye, has improved user's visual experience.

Further, as shown in fig. 1 and fig. 3, the pot body 1 has a visible area 115 and a shielding area 116 shielded by the fluid cover 2 along the circumferential direction, the visible area 115 is located at the front side of the pot body 1, and the shielding area 116 is located at the rear side of the pot body 1.

It should be noted that the "front side" herein is a side of the cooking appliance facing a user when the user uses the cooking appliance, and correspondingly, the "rear side" is a side facing away from the user. The visual area 115 faces to a user side, and when the cooking appliance is used, the cooking state in the cooking cavity 111 can be directly observed through the visual area 115, so that the use experience is improved.
