If the steam outlet of the steam guiding tube is less than 1 cm below the liquid level, when the steaming speed is too fast, the steam that is sprayed hits the liquid surface, which may cause the liquid at the steam outlet to spread out, and the steam discharged from the steam outlet may not be sufficient. In contact with the liquid, the cooking time is slow; if the steam outlet of the steam guiding tube is more than 3 cm below the liquid surface, the steam forms a large amount of foam under the liquid surface, and the foam rises from below the liquid surface to burst above the liquid surface, resulting in above the liquid level of the pot body.
- the inner wall is bonded with a large amount of food to be cooked, which affects the user experience.
- the steam inlet 310 extends toward the bottom of the pot body 3 to provide a guiding portion 320, and one end of the steam guiding tube is fitted to the guiding portion 320.
- the steam inlet 310 is a through hole directly formed in the lid 300. If the steam guiding tube is directly assembled at the through hole, it is inconvenient to assemble, and a guiding portion 320 is extended at the steam inlet, and the guiding portion is used as an assembly of the steam guiding tube.
- the component, the guide tube 320 may be integrally formed with the steam inlet, or the guide portion may be fixed to the steam inlet by mounting the firmware.
- the steam guiding tube is fixed to the guiding portion by one of a tight fitting, a turnbucking or a magnetic structure, and the diameter of the steam guiding portion at the fitting portion is larger than or equal to the diameter of the lower portion of the guiding portion.
- the tight fitting, the turnbuckle or the magnetic structure is the main structure of the existing assembly, and the steam guiding tube can be easily disassembled by the above-mentioned assembly structure.
- the guiding tube 320 can adopt a hose to assemble the steam guiding tube to the guiding tube by pressing force; when one of the turning buckle or the magnetic structure is adopted, the guiding tube 320 can adopt a hard tube. It is correspondingly provided with a snap mechanism or a groove for easy disassembly.
- the sealing assembly 330 for covering the end edge of the guiding portion, the sealing assembly introducing all the steam into the steam guiding tube,
- the steam guiding tube 500 is sleeved on the sealing assembly 330, and the inner wall of the steam guiding tube is tightly fitted to the largest outer wall of the sealing assembly.
- the steam guiding tube 500 includes a first steam outlet 510 at a lower end and at least one second steam outlet 520 at a side portion.
- Two steam outlets are opened on the steam guiding tube. Since the steam is discharged from the top to the bottom, if only the first steam outlet at the end discharges the steam, the first steam outlet has a larger pore size, and the steam generates a larger bubble under the liquid surface. After the liquid absorbs the heat carried by the steam, the bubble is compressed and ruptured by the cold, and after the rupture, a cracking sound is generated in the liquid, which affects the user experience; therefore, a second steam outlet is opened at the side of the steam guiding tube, and the second steam outlet is used as the main steam.
- the discharge outlet since the number of the second steam outlets is more than one, the diameter of each corresponding second steam outlet becomes smaller, a large amount of steam is discharged from the second steam outlet, and the steam discharged from the second steam outlet is formed in the liquid. Small bubbles, bursting produces less sound.
- the second steam outlet 520 is a sound absorbing hole, and the sound absorbing hole is away from the first steam outlet 510, and the sound absorbing hole is disposed around the pipe wall of the steam guiding pipe.
- the second steam outlet is disposed away from the first steam outlet, and a second steam outlet is arranged around the pipe wall to facilitate guiding most of the steam to be discharged from the circumferential side of the pipe wall, the discharge efficiency is high, and there is less steam from the first A steam outlet is discharged, even if discharged, since the amount of steam is reduced, the foam formed in the liquid is correspondingly small; that is, the corresponding second steam outlet 520 in the present invention is a sound-absorbing hole.
- the upper middle portion of the steam guiding tube is provided with an anti-back suction hole 530 which is away from the second steam outlet.
- the liquid is continuously supplied with steam so that the pressure in the liquid is larger than the pressure of the steam guiding tube. If the steam supply is cut off, the pressure in the liquid surface is greater than the pressure in the steam guiding tube, and the liquid will flow from the bottom to the bottom.
- the steam guiding tube is poured in, and an anti-back suction hole is arranged in the upper middle portion of the steam guiding tube, so that the influx liquid is discharged from the anti-back suction hole to prevent the liquid from being bound from the steam guiding tube into the steam inlet, and the lid is closed.
- the distance d2 between the lowest end of the anti-back suction hole 530 and the highest end of the second steam outlet 520 is 10-50 mm.
- the distance relationship between the anti-back suction hole and the second steam outlet is defined. If the distance between the lowest end of the anti-back suction hole and the highest end of the second steam outlet is less than 10 mm, the liquid will go down There is a buffering force in the steam guiding tube, and the anti-back suction hole can not discharge the liquid.
- the liquid still flows from the steam guiding tube into the steam inlet, causing pollution to the lid; if the anti-reverse suction hole has the lowest end and the second steam If the distance between the highest end of the outlet is greater than 50mm, the distance between the two is too large, except that the overall length of the steam guiding tube needs to be long, the height of the corresponding pot body needs to be increased, and the liquid influx into the steam guiding tube will not exceed 50mm. That is, the structure with or without the anti-back suction hole has no influence on the anti-back suction.
- the steam guiding tube is prepared from a hard plastic.
- the hard plastic is used to facilitate the steam drainage, and the steam guiding tube is prevented from being bent after being inserted into the liquid to touch the hard object, which is not favorable for steam discharge; and the steam conduit formed by the steam guiding tube has the same cross-sectional aperture from top to bottom, and the steam is circulated.
- the speed is relatively stable.
- the above pot body is a heat preservation pot body.
- the use of the heat preservation pot body ensures that the heating capacity of the pot body can be improved regardless of the steam heating or other heating methods, and the heat energy is not lost and energy is saved.
- the steam cooking rice cooker of each of the above embodiments is preferably used for cooking rice.
