[0037] Please refer to Fig. 9 The upper part of the steam diversion hole 152 is sealed and slidably connected with an arc-shaped baffle 16, and a tension spring is fixedly connected between the lower side of the arc-shaped baffle 16 and the connecting piece 14.

[0038] Please refer to Fig. 9 and Fig.10The upper sealing rotation in the lower annular cavity 701 is connected with a shielding member 18, and the vertical fan-shaped holes 141 and the vertical arc-shaped holes 151 are both blocked and matched with the shielding member 18. Initially, the six vertical fan-shaped holes 141 and the six vertical arc-shaped holes 151 are blocked by the shielding member 18. The shielding member 18 is provided with six annularly distributed fan-shaped connecting holes 181 and six annularly distributed arc-shaped notches 182. The fan-shaped connecting holes 181 are connected and matched with the adjacent vertical fan-shaped holes 141, and the arc-shaped notches 182 are connected and matched with the adjacent vertical fan-shaped holes 141.

A high-temperature resistant motor 20 is installed in the lower annular cavity 701, and the output shaft of the high-temperature resistant motor 20 is transmitted to the shielding member 18 through gears and racks.

[0039] When using the device to cook food, the user places the food to be cooked into the heating chamber of the steamer body 1 after opening the cabinet door 2, and closes the cabinet door 2. Then the user adds water to the upper side of the heating element 5 in the installation shell 3 through the liquid replenishing tube 302, and stops when the water level in the installation shell 3 is above the flow element 8. At this time, the user sets the temperature and heating time in the three heating chambers through the three control panels in turn. After the setting is completed, the control terminal starts the blower and the burner 4. The blower injects air into the installation shell 3 through the air inlet pipe 301. The burner 4 starts and burns the gas to heat the heating element 5. The heating element 5 exchanges heat with the water on its upper side to increase the water temperature until steam is generated. The steam in the installation shell 3 enters the corresponding heating chamber through the heat exchange tube 10 and the three conduits 11 respectively. In the process of steam entering the heating chamber, the control terminal controls the flow rate of steam entering the adjacent heating chambers through the three solenoid valves, thereby controlling the temperature in the heating chamber.

[0040] When the burner 4 is started to burn gas, the flue gas generated passes through the cylinder of the heat receiving part 5 and through the connecting pipe 6 to enter the flow control part 7. In the process of the flue gas passing through the connecting pipe 6, the flue gas blows a plurality of inner blades 12, and the plurality of inner blades 12 together drive the connecting pipe 6 to rotate, and the connecting pipe 6 drives a plurality of outer blades 13 to rotate, and the outer blades 13 stir the water in the mounting shell 3 to make the water flow in the mounting shell 3, thereby improving the uniformity of the heat exchange between the heat receiving part 5 and the water, thereby improving the efficiency of heating the water and shortening the time required for the water to boil.

[0041] After the smoke enters the flow control member 7, the smoke passes through a plurality of side arc holes 702 and enters the lower annular cavity 701. Then, the smoke in the lower annular cavity 701 enters a plurality of circulation members 8 and flows along them. Finally, the smoke flows out of the circulation members 8 and enters the exhaust member 9, and is discharged from the steamer body 1 through the exhaust member 9. During the flow of the smoke in the connecting pipe 6, the flow control member 7 and the circulation member 8, the heat in the smoke is transferred to the water through the above three members, and the heat in the smoke is utilized, and the temperature of the smoke is reduced, thereby reducing the impact on the kitchen temperature. At the same time, the temperature of the water is increased, the time required for the water to boil is shortened, and the impact on the food during the heating of the water is reduced.

[0042] After the water in the installation shell 3 boils, the control terminal compares the highest temperature of the three heating chambers set by the user with the temperature of the steam corresponding to the pressure in the steamer body 1 (the pressure is proportional to the boiling point of water, and the temperature of the steam generated after the water boils is consistent with the temperature when the water boils). If the temperature set by the user is lower than the temperature of the steam corresponding to the pressure in the steamer body 1, the above steps are repeated to allow the flue gas to circulate in several circulation parts 8, thereby improving the heating efficiency of the water in the installation shell 3, and then the control terminal reduces the flow rate of the gas in the burner 4, thereby saving gas energy.

[0043] If the temperature set by the user is greater than the temperature of the steam corresponding to the pressure in the steam box body 1, the generated steam needs to be reheated at this time. The specific operation is as follows: the control terminal starts the high temperature resistant motor 20, and the high temperature resistant motor 20 drives the shielding member 18 to rotate 30° through the gear and rack. The shielding member 18 drives the six lateral shielding plates 19 to rotate together. After the shielding member 18 rotates, the six vertical fan-shaped holes 141 and the six vertical arc holes 151 are unblocked, and the shielding member 18 blocks the steam generated by the steam box body 1. The component 18 drives the fan-shaped connecting hole 181 thereon to correspond to and communicate with the adjacent vertical fan-shaped hole 141, and the arc-shaped notch 182 corresponds to and communicates with the adjacent vertical arc-shaped hole 151. The lateral baffle plate 19 blocks the adjacent side arc-shaped hole 702 (that is, the smoke cannot enter the lower annular cavity 701 through the side arc-shaped hole 702). At this time, the smoke in the connecting pipe 6 passes through the six vertical fan-shaped holes 141 and the six fan-shaped connecting holes 181, then passes through the flow control component 7 and enters the connecting component 14.

[0044] After the water in the installation shell 3 boils and generates steam, the steam passes through the notch at the bottom of the heat exchange tube 10 and enters the three steam diversion holes 152. As the volume of the steam in the installation shell 3 gradually increases, the pressure of the steam in the installation shell 3 increases until the pressure of the steam is greater than the tension of the tension springs adjacent to the arc baffle 16. The steam in the steam diversion holes 152 pushes the adjacent arc baffles 16 upward respectively, stretching the tension springs adjacent to the arc baffles 16. The arc baffles 16 drive the adjacent arc blocking plates 17 upward, so that the arc blocking plates 17 release the blockage of the connecting piece 14 and the heat exchange tube 10. At this time, the flue gas in the connecting piece 14 enters the three heat exchange chambers 15 and flows downward along the heat exchange chambers 15. In the process of the flue gas flowing in the heat exchange chamber 15, the heat in the flue gas is transferred to the heat exchange tube 10. The heat exchange tube 10 exchanges heat with the steam in the steam diversion holes 152, so that the heat of the steam entering the conduit 11 increases, thereby performing secondary heating on the steam.

[0045] After the smoke flows to the end of the heat exchange chamber 15, the smoke enters the upper annular chamber 153 and enters the lower annular chamber 701 through the adjacent vertical arc hole 151. Then the smoke in the lower annular chamber 701 is discharged through a plurality of flow parts 8 and exhaust parts 9. In this way, when the steam temperature required for cooking is greater than the steam temperature corresponding to the pressure in the steamer body 1, the smoke is used to heat the steam for a second time to increase the steam temperature. Then the smoke exchanges heat with the water in the mounting shell 3, thereby achieving the purpose of saving energy while increasing the steam temperature.

[0046] If the user does not fully utilize the steamer body 1 when using it, that is, there is no food in one or two heating chambers (hereinafter, the operation of only the lowest heating chamber is used as an example for explanation), after starting the steamer body 1, the control terminal controls the lowest solenoid valve to start, so that the steam enters the lowest heating chamber through the adjacent conduit 11, and then after the steam enters the three steam diversion holes 152, since the conduits 11 corresponding to the upper two heating chambers are in a closed state, that is, the arc baffles 16 corresponding to the above two conduits 11 cannot be pushed upward by the steam, at this time, only the steam in a single steam diversion hole 152 pushes the adjacent arc baffle 16 and then enters the corresponding conduit 11, and at the same time, only the corresponding arc blocking plate 17 releases the blockage of the connecting piece 14 and the heat exchange cylinder 10. In this way, the smoke only flows through a single heat exchange chamber 15, so that the flow area of ​​the smoke and steam is reduced, the concentration of the smoke in the heat exchange chamber 15 and the concentration of the steam in the steam diversion hole 152 are increased, and the efficiency of the heat exchange between the smoke and the steam is maintained.

[0047] After one of the heating chambers reaches the time set by the user, the control terminal blocks the corresponding conduit 11 through the solenoid valve, so that steam cannot continue to enter the heating chamber. The user opens the cabinet door 2 and takes out the food in the corresponding heating chamber. After the use of the steamer body 1 is over, the control terminal controls the high temperature resistant motor 20 to reverse, and repeats the above-mentioned step of rotating the shielding member 18 30° in reverse to complete the resetting of the shielding member 18. Then the user opens the mounting plate and the sealing cover, adds a descaling agent to the inside of the mounting shell 3 through the cleaning hole 303, waits for a period of time, and then discharges the water and scale in the mounting shell 3.

[0048] While the steamer is working and heating the food inside, sometimes the user will add seasoning to the food again or check the degree of doneness of the food. At this time, the user needs to open the steamer. After the steamer is turned on, the steam remaining in the steamer is quickly discharged and the temperature inside the steamer decreases. After the user subsequently turns off the steamer, it still takes time for the temperature inside the steamer to return to normal. This period of time has a great impact on the quality of the food.

[0049] Example 2: Based on Example 1, please refer to Figure 2 and Fig.11 , and also includes three handles 21 equidistantly distributed up and down, the handle 21 is rotatably connected to the middle of the front side of the adjacent cabinet door 2, the handle 21 is slidably connected to two symmetrically distributed connecting rods 22, the connecting rod 22 is slidably connected to the adjacent cabinet door 2 left and right, the steamer body 1 is provided with grooves equidistantly distributed and respectively limited by the connecting rods 22 adjacent to the left, the connecting rod 22 on the right is fixedly connected to the first magnet 23, and the first magnet 23 is slidably connected to the adjacent cabinet door 2 left and right.

[0050] Please refer to Fig.12 and Fig.13 The right side of the steamer body 1 is slidingly connected with three second magnets 24 equidistantly distributed up and down. Initially, the second magnet 24 is at the same height as the adjacent first magnet 23, and the second magnet 24 cooperates with the adjacent first magnet 23 by magnetic attraction. The upper part of the conduit 11 is fixedly connected and connected with a blocking shell 25, and a blocking member 26 is sealingly and slidingly connected in the front and rear of the blocking shell 25. The blocking member 26 cooperates with the adjacent conduit 11 for blocking. Initially, the blocking member 26 blocks the adjacent conduit 11, and a tension spring is fixedly connected between the blocking member 26 and the adjacent blocking shell 25, and a pull rope 27 is fixedly connected to the blocking member 26 and the adjacent second magnet 24.

[0051] Please refer to Fig.10 A pressure measuring plate 28 is sealingly and slidably connected to the lateral shielding plate 19 , and a spring is fixedly connected between the pressure measuring plate 28 and the adjacent lateral shielding plate 19 .

[0052] After the user puts the food into the heating chamber, the user closes the cabinet door 2 and turns the corresponding handle 21. The handle 21 drives the two adjacent connecting rods 22 to move away from each other, and finally the connecting rod 22 on the left is inserted into the corresponding groove on the steamer body 1. The connecting rod 22 on the right drives the adjacent first magnet 23 to move. When the first magnet 23 moves to the extreme position, the first magnet 23 attracts the adjacent second magnet 24 to move left through magnetic attraction. The second magnet 24 pulls the adjacent blocking member 26 forward through the adjacent pull rope 27 and stretches the adjacent tension spring of the blocking member 26. The blocking member 26 releases the blockage of the adjacent conduit 11. At this time, the steps of Example 1 are repeated to heat the food in the heating chamber.

[0053] When the steamer body 1 is in working state and the user needs to open the cabinet door 2 (hereinafter, the opening of the lowest heating chamber is used as an example for explanation), the user turns the handle 21, and the handle 21 drives the two connecting rods 22 to move closer to each other, so that the connecting rod 22 on the left loses contact with the adjacent groove on the steamer body 1, and the limit on the cabinet door 2 is released. At the same time, the connecting rod 22 on the right drives the adjacent first magnet 23 to reset, and the magnetic attraction between the first magnet 23 and the adjacent second magnet 24 gradually decreases. The blocking member 26 moves backward under the action of the adjacent tension spring, and the blocking member 26 pulls the adjacent second magnet 24 to the right and resets through the adjacent pull rope 27. At this time, the blocking member 26 blocks the adjacent duct 11 again to prevent the steam in the steamer body 1 from still replenishing the heating chamber when the user opens the cabinet door 2, resulting in high-temperature steam always existing in the heating chamber, making it difficult to take out the food in the heating chamber.

[0054] After the blocking member 26 blocks the adjacent conduit 11, the volume of steam generated per unit time by the water in the installation shell 3 is greater than the volume of steam required to maintain the temperature of the three heating chambers per unit time. At this time, the steam gathers in the installation shell 3. At the same time, because the conduit 11 is blocked, the pressure in the conduit 11 is consistent with the pressure in the corresponding steam diversion hole 152. At this time, the steam in the steam diversion hole 152 no longer continues to flow into the adjacent conduit 11, so that the arc baffle 16 moves downward under the action of the adjacent tension spring. At the same time, the arc baffle 16 drives the adjacent arc blocking plate 17 to move downward and re-blocks the corresponding position on the connecting member 14 that is connected to the heat exchange chamber 15, so that the unit The volume of flue gas entering the connecting piece 14 within a certain time period is greater than the volume of flue gas entering the heat exchange chamber 15 through the connecting piece 14 within a certain time period, so that the flue gas pressure in the connecting piece 14 increases. This part of the flue gas pushes the six pressure measuring plates 28 to move, compressing the springs adjacent to the pressure measuring plates 28, so that the pressure measuring plates 28 release the blockage of the adjacent lateral baffles 19. At this time, part of the flue gas in the connecting piece 14 directly enters the lower annular cavity 701 through the six lateral baffles 19, and flows along the flow piece 8, so that the overall temperature of the flue gas in the flow piece 8 increases, thereby improving the heating efficiency of the water in the installation shell 3, and thereby increasing the volume of steam generated by the water in the installation shell 3 within a certain time period.

[0055] After the user closes the cabinet door 2 again, the above steps are repeated to release the blocking of the adjacent conduit 11 by the blocking member 26. At this time, the steps of Example 1 are repeated, and the steam accumulated in the installation shell 3 enters the corresponding heating chamber through the steam diversion hole 152 and the corresponding conduit 11, so that the temperature in the heating chamber recovers quickly, thereby shortening the time for the temperature in the heating chamber to recover, thereby reducing the impact of opening the cabinet door 2 on the quality of the food in the heating chamber.
