Adding appropriate amount of water into the heating pots, inserting the lower end of the central shaft into the rotating disc, rotating the central shaft with the rotating disc, making the steam holes correspond to the local heating device, and discharging the steam generated in the heating pots. The steaming drawer is placed at the upper end of the shell, food is placed in the steaming drawer, and then the steaming drawer is covered by the steaming cover. And starting the steamer, starting the local heating device and the local refrigerating device, and refrigerating or heating the corresponding heating pot. The heating pan corresponding to the local heating device is an evaporating pan, and the heating pan adjacent to the evaporating pan along the rotating direction of the rotating disk is a condensing pan. Steam generated in the evaporating pot enters the steaming drawer through the steam holes and the vent holes to heat food and improve the pressure inside the evaporating pot. When the pressure inside the steamer exceeds the limiting pressure of the pressure limiting valve, the steamer can discharge the air and steam inside the steamer from the pressure limiting valve, and the proportion of the air inside the steamer is reduced.

The condensed water flowing down from the vent hole of the steaming drawer 6 flows into the steam hole under the action of the concave cambered surface and enters the heating pot 3, so that the recovery of the steam is realized. The upper end of the sealing plate 5 is a concave cambered surface and is used for recycling condensed water.
The steamer includes: the object blocking net 53 is net-shaped, the object blocking net 53 is arranged in the shell 1, the object blocking net 53 is arranged below the steaming drawer 6 and above the sealing plate 5, and the object blocking net 53 is arranged at the lowest end of the concave cambered surface.
The steam in the heating pan 3 is dispersed and ascended after passing through the steam holes 52 and the barrier net 53, and the steaming drawer 6 is heated comprehensively. When the food in the steamer tray 6 is boiled, sputtering can be generated, and some larger food is taken out and falls to the steam holes 52 from the vent holes to block the steam holes 52. The blocking net 53 is arranged for preventing food residues from blocking the steam holes 52, and is used for dispersing the steam discharged from the steam holes 52 and uniformly heating the steam drawer 6.
The steamer includes: and the four thermometers are arranged in the heating pot 3 and are positioned below the water surface.
A temperature detector is provided for measuring the temperature in the heating pan 3. By controlling the rotation intervals of the local heating device 21, the local refrigerating device 22 and the rotating disk 2, the temperature of the condensing pan can reach 100 ℃ when the condensing pan becomes an evaporating pan, the generation of steam can be continuous, and the heating efficiency of the steaming pan to food is improved.
The steamer includes: the number of the heating pans 3 is at least three.
If the condensation and the cooling are carried out in the same heating pot 3, the initial temperature of the condensation pot is 100 ℃, so that the steam cannot be absorbed by the condensation pot, and is discharged by the pressure limiting valve 8 under the action of the pressure in the steaming pot, thereby reducing the cooling effect of the steaming pot on the steam. The cooling, the evaporation and the condensation are respectively carried out in three different heating pots 3, so that the temperature in the condensing pot can be changed from low to high, and the condensing effect of the condensing pot on steam is improved.
The working process of the embodiment is as follows: after a proper amount of water is added to the plurality of heating pots 3, the lower end of the central shaft 51 is inserted into the rotary disk 2 so that the central shaft 51 can rotate with the rotary disk 2, and the plurality of steam holes 52 correspond to the local heating means 21 so that steam generated in the heating pots 3 can be discharged. The steaming drawer 6 is placed at the upper end of the casing 1, food is placed in the steaming drawer 6, and then the steaming drawer 6 is covered with the steaming cover 7. And starting the steamer, starting the local heating device 21 and the local refrigerating device 22, and refrigerating or heating the corresponding heating pan 3. The heating pan 3 corresponding to the local heating device 21 is an evaporating pan, and the heating pan 3 adjacent to the evaporating pan in the rotating direction of the rotating disk 2 is a condensing pan. The steam generated in the steamer enters the steamer tray 6 through the steam holes 52 and the vent holes to heat the food and increase the pressure inside the steamer. When the pressure inside the steamer exceeds the limiting pressure of the pressure limiting valve 8, the steamer can discharge the air and steam inside the steamer from the pressure limiting valve 8, and the proportion of the air inside the steamer is reduced. Steam in the steam evaporating pot in the evaporating pot sequentially enters the condensing pot through the steam recovery pipeline 54, the steam condensing pipeline 31 and the cage balls 32 and is dispersed into a plurality of small air flows under the action of the cage balls 32, and the contact area of the steam and water is increased. The steam is condensed under the action of the water with lower temperature in the condensing pan, the steam is recovered, and the water in the condensing pan is increased at the moment. The rotary plate 2 rotates to make the original condensing pan become an evaporating pan, and the heating pan 3 adjacent to the evaporating pan at that time in the rotating direction of the rotary plate 2 becomes a condensing pan. Due to the heating effect of the steam, the temperature of the heating pot 3 is higher, and the heating boiling time can be reduced. The rotating disc 2 rotates periodically, so that the water in the evaporating pot does not dry up. The local refrigerating device 22 can cool the water in the heating pan 3, so that the initial temperature of the condensing pan is reduced, and the absorption efficiency of the condensing pan on the steam is improved. The heating pan 3 corresponding to the local refrigerating device 22 is not a condensing pan or an evaporating pan, so that the initial temperature of the condensing pan is reduced, and the absorption efficiency of the condensing pan on steam is improved.
The condensed water flowing down from the vent hole of the steaming drawer 6 flows into the steam hole under the action of the concave cambered surface and enters the heating pot 3, so that the recovery of the steam is realized. The steam in the heating pan 3 is dispersed and ascended after passing through the steam holes 52 and the barrier net 53, and the steaming drawer 6 is heated comprehensively. Food waste will be intercepted by the barrier net 53.
A control method of a steamer capable of recycling steam comprises the following steps: starting the steamer, starting the local heating device 21 to heat the steamer for 5 minutes, and then carrying out the following steps: the method comprises the following steps: starting the local refrigerating device 22 to refrigerate the heating pan 3 above the local refrigerating device, and measuring the temperature T1 through a temperature detector in the heating pan 3; step two: if T1>T, continue cooling until T1= T, turn off the local cooling device 22; if T1<T or T1= T, turning off the local refrigeration unit 22; step three: rotating the rotating disc 2 by a degree A through a rotation driving system; step four: sequentially repeating the first step, the second step and the third step until the steamer is closed; wherein, T1<The temperature of the mixture is 100 degrees,
and N is the number of the heating pans 3.
Because the heating pans 3 are uniformly arranged, after rotating for a degrees, the upper end of the steam condensation pipeline 31 can be matched with the steam recovery pipeline 54, so that the recovery of steam is realized. The size of T is adjusted, so that the time for the water in the condensing pot to rise from T to 100 ℃ is the same as the time for the water in the heating pot 3 to cool to the temperature T, and the condensing pot can reach 100 ℃ when becoming an evaporating pot.
The above-mentioned embodiments are only a part of the embodiments of the present invention, and not all embodiments, and other embodiments obtained by those skilled in the art without inventive efforts based on the embodiments of the present invention belong to the protection scope of the present invention.
