When the food is baked, part of the heat generated by the inner container is transferred to the boiler by heat transfer, and the heat will cause the water temperature in the boiler to rise, at which time the liquid water in the boiler will evaporate to form water vapor, therefore, the related art has the problem that the water vapor formed by the evaporation of the liquid water in the boiler enters the inner container when the food with high crispness (such as egg tarts or cow horn buns) is baked, which results in insufficient crispness of the food, thereby affecting the eating experience of the food.

[0003] Therefore, the prior art needs to be improved and developed. It should be noted that the above information disclosed in this part is only used to understand the background of the utility model concept, and therefore can contain information that does not constitute the prior art.

[0017] Further, the fourth port is fixed with a mounting seat, the mounting seat is slidably connected with the connecting rod, and the steam switching device for the steam baking integrated box further comprises a second sealing assembly arranged between the mounting seat and the fourth port.

[0018] Since the second sealing assembly is arranged between the mounting seat and the fourth port, the technical scheme can effectively avoid the situation that water vapor formed by evaporation of liquid water in the boiler leaks in the gap between the mounting seat and the fourth port and enters the inner container.

[0034] a sealing mechanism 8 located in the multi-way pipe 4 and in sliding connection with the multi-way pipe 4;

[0035] a linear driving assembly 9 for driving the sealing mechanism 8 to slide in the multi-way pipe 4, so as to switch the boiler 2 between two states of being in communication with the steam discharge assembly 3 through the second port 6 and the first port 5 and being in communication with the inner container 1 through the second port 6 and the third port 7.

[0036]

[0037] ​The embodiment provides a steam switching device for a steam-baking integrated box, which is applied to a steam-baking integrated box having a steaming mode and a baking mode, and the steam-baking integrated box comprises an inner container 1, a boiler 2 and a steam discharge assembly 3, the inner container 1 can be an existing inner container 1, the inner container 1 can place food to be steamed or baked and heat the food placed therein, the boiler 2 can be an existing boiler 2, the boiler 2 can store liquid water and form water vapor by heating the liquid water stored therein, and the steam discharge assembly 3 can be an exhaust pipe. The multi-way pipe 4 of the embodiment has a first port 5, a second port 6 and a third port 7, the second port 6 is preferably located between the first port 5 and the third port 7, the first port 5 is communicated with the steam discharge assembly 3 through a steam conveying pipe 17, and the third port 7 is communicated with the inner container 1 through another steam conveying pipe 17. The sealing mechanism 8 of the embodiment can be a cylindrical slider, the diameter of the cylindrical slider is the same as the inner diameter of the multi-way pipe 4, that is, there is no gap between the sealing mechanism 8 and the multi-way pipe 4 for water vapor to pass through, the sealing mechanism 8 is located in the multi-way pipe 4 and is in sliding connection with the multi-way pipe 4, that is, the sealing mechanism 8 can slide relative to the multi-way pipe 4. The linear driving assembly 9 of the embodiment can be a cylinder, an oil cylinder or an electric cylinder and the like which can drive the movement of the body linearly, the linear driving assembly 9 is connected with the sealing mechanism 8, and the linear driving assembly 9 is used to drive the sealing mechanism 8 to slide in the multi-way pipe 4. Specifically, when the food needs to be baked, the linear driving assembly 9 is controlled to drive the sealing mechanism 8 to slide in the multi-way pipe 4, so that the boiler 2 is switched to a state of being communicated with the first port 5 through the second port 6 to be communicated with the steam discharge assembly 3, at this time, the water vapor formed by the evaporation of the liquid water in the boiler 2 will be discharged from the steam-baking integrated box through the steam discharge assembly 3, and when the food needs to be steamed, the linear driving assembly 9 is controlled to drive the sealing mechanism 8 to slide in the multi-way pipe 4, so that the boiler 2 is switched to a state of being communicated with the third port 7 through the second port 6 to be communicated with the inner container 1, at this time, the water vapor formed by the evaporation of the liquid water in the boiler 2 will enter the inner container 1. Therefore, the boiler 2 can be switched between the two states of being communicated with the first port 5 through the second port 6 to be communicated with the steam discharge assembly 3 and being communicated with the third port 7 through the second port 6 to be communicated with the inner container 1 by driving the sealing mechanism 8 to slide in the multi-way pipe 4 by using the linear driving assembly 9, that is, the boiler 2 and the inner container 1 can be communicated or cut off by driving the sealing mechanism 8 to slide in the multi-way pipe 4 by using the linear driving assembly 9.

[0038] The specific process of steaming food in the steam-baking integrated box of this embodiment can be: opening the steam-baking integrated box, and placing food into the inner container 1; closing the steam-baking integrated box; controlling the linear drive assembly 9 to drive the sealing mechanism 8 to slide in the multi-way pipe 4, so as to switch the boiler 2 to the state of communicating with the third port 7 through the second port 6 to be in communication with the inner container 1; and controlling the boiler 2 and the inner container 1 to heat. The specific process of baking food in the steam-baking integrated box of this embodiment can be: opening the steam-baking integrated box, and placing food into the inner container 1; closing the steam-baking integrated box; controlling the linear drive assembly 9 to drive the sealing mechanism 8 to slide in the multi-way pipe 4, so as to switch the boiler 2 to the state of communicating with the first port 5 through the second port 6 to be in communication with the steam discharge assembly 3. It should be understood that when steaming food, all water vapor formed by evaporation of liquid water in the boiler 2 enters the inner container 1, and when baking food, all water vapor formed by evaporation of liquid water in the boiler 2 is discharged through the steam discharge assembly 3.

[0039] The steam switching device for the steam-baking integrated box provided in the present application can realize the communication or interruption of the boiler 2 and the inner container 1 by driving the sealing mechanism 8 to slide in the multi-way pipe 4 by the linear drive assembly 9, so that when baking food, the present application can prevent water vapor formed by evaporation of liquid water in the boiler 2 from entering the inner container 1 by interrupting the boiler 2 and the inner container 1, thereby effectively avoiding the problem of insufficient final crispness of food caused by water vapor formed by evaporation of liquid water in the boiler 2 entering the inner container 1, and further effectively improving the eating experience of food. In addition, since the boiler 2 of the prior art communicates with the inner container 1, and a large amount of water vapor will still be generated in the boiler 2 after steaming food, at this time, baking food cannot be performed, so after steaming food, the prior art needs to wait for the water in the boiler 2 to cool to room temperature before baking food by the steam-baking integrated box, that is, the prior art cannot quickly switch the steam-baking integrated box from the steaming mode to the baking mode. Since the present application can switch the boiler 2 between the state of communicating with the inner container 1 and the state of communicating with the steam discharge assembly 3 by driving the sealing mechanism 8 to slide in the multi-way pipe 4 by the linear drive assembly 9, after steaming food, the present application only needs to interrupt the boiler 2 and the inner container 1 to bake food, that is, the present application can quickly switch the steam-baking integrated box from the steaming mode to the baking mode.

[0040] In some preferred embodiments, the sealing mechanism 8 comprises a piston, the second port 6 is located between the first port 5 and the third port 7, the pipe segment between the second port 6 and the third port 7 in the multi-way pipe 4 is provided with a limiting reverse buckle 10, and the piston completely blocks the opening of the limiting reverse buckle 10 when the piston is in contact with the limiting reverse buckle 10. Specifically, when the piston slides to be in contact with the limiting reverse buckle 10, the water vapor generated by the evaporation of the liquid water in the boiler 2 cannot enter the third port 7 through the opening of the limiting reverse buckle 10 because the piston completely blocks the opening of the limiting reverse buckle 10, so the water vapor generated by the evaporation of the liquid water in the boiler 2 can only enter the steam discharging assembly 3 through the first port 5 but cannot enter the inner container 1 through the third port 7. Since the pipe segment between the second port 6 and the third port 7 in the multi-way pipe 4 of this embodiment is provided with the limiting reverse buckle 10, the limiting reverse buckle 10 can prevent the water vapor generated by the evaporation of the liquid water in the boiler 2 from entering the inner container 1 by being in contact with the piston, and the limiting reverse buckle 10 can also limit the sliding position of the piston, so this embodiment can effectively avoid the situation that the water vapor generated by the evaporation of the liquid water in the boiler 2 can enter the inner container 1 because the piston slides to the position where the third port 7 is located or to the side of the third port 7 away from the first port 5.

[0041] In some preferred embodiments, the steam switching device for the steam-baking integrated box further comprises a quick connector 11, the quick connector 11 is threadedly connected with the first port 5, and the sealing mechanism 8 completely blocks the air inlet of the quick connector 11 when the boiler 2 is in the state of being in communication with the inner container 1. Specifically, since the quick connector 11 of this embodiment is threadedly connected with the first port 5, that is, the diameter of the air inlet of the quick connector 11 is smaller than the pipe diameter of the multi-way pipe 4. Since the quick connector 11 of this embodiment has the advantage of fast connection, this embodiment can effectively improve the convenience of connecting the multi-way pipe 4 and the steam discharging assembly 3. It should be understood that since the diameter of the air inlet of the quick connector 11 is smaller than the pipe diameter of the multi-way pipe 4, and this embodiment only needs to make the sealing mechanism 8 completely block the air inlet of the quick connector 11 to prevent the water vapor generated by the evaporation of the liquid water in the boiler 2 from entering the steam discharging assembly 3 through the quick connector 11, and this embodiment prevents the water vapor generated by the evaporation of the liquid water in the boiler 2 from entering the inner container 1 by making the piston in contact with the limiting reverse buckle 10, the inner diameter of the limiting reverse buckle 10 is smaller than the pipe diameter of the multi-way pipe 4, so this embodiment can set the diameter of the piston to be greater than the diameter of the air inlet of the quick connector 11 and the inner diameter of the limiting reverse buckle 10 and smaller than the pipe diameter of the multi-way pipe 4, that is, the sealing mechanism 8 of this embodiment does not contact the inner wall of the multi-way pipe 4, thereby effectively avoiding the situation that the sealing mechanism 8 is hard rubbed with the inner wall of the multi-way pipe 4 during the sliding process due to the contact between the sealing mechanism 8 and the inner wall of the multi-way pipe 4, the sealing mechanism 8 is worn, and further effectively avoiding the situation that the sealing mechanism 8 is not airtight enough due to the wear of the sealing mechanism 8, and part of the water vapor can accidentally enter the inner container 1 or the steam discharging assembly 3.

[0042] In some preferred embodiments, the steam switching device for the steam-baking integrated oven further comprises a first sealing assembly arranged between the quick connector 11 and the first port 5. The first sealing assembly of this embodiment is preferably a sealing ring. Since this embodiment is arranged with the first sealing assembly between the quick connector 11 and the first port 5, it can effectively avoid the situation that the steam formed by the evaporation of the liquid water in the boiler 2 leaks through the gap between the quick connector 11 and the first port 5 and the water vapor entering the inner container 1 is insufficient.

[0043] In some preferred embodiments, the multi-way pipe 4 further has a horizontal pipe section, the two ends of the horizontal pipe section are the first port 5 and the fourth port 12, the axes of the second port 6 and the third port 7 are perpendicular to the axis of the horizontal pipe section, the second port 6 is located on the side of the third port 7 close to the first port 5, the linear driving assembly 9 comprises a driving mechanism 91 and a connecting rod 92, the connecting rod 92 is slidingly installed on the fourth port 12 and fixedly connected with the sealing mechanism 8, the driving mechanism 91 is connected with the connecting rod 92, and the driving mechanism 91 is used to drive the connecting rod 92 to move horizontally to drive the sealing mechanism 8 to slide in the horizontal pipe section. The driving mechanism 91 of this embodiment can be a screw rod module or a linear module mechanism. Since the connecting rod 92 of this embodiment is fixedly connected with the sealing mechanism 8, the sealing mechanism 8 can be driven to slide in the horizontal pipe section by driving the connecting rod 92 to move horizontally by using the driving mechanism 91.

[0044] In some preferred embodiments, the driving mechanism 91 comprises a first motor 911, a screw rod 912 and a bracket 913, the output end of the first motor 911 is connected with the screw rod 912, the screw rod 912 is threadedly connected with the bracket 913, the bracket 913 is fixedly connected with the connecting rod 92, and the first motor 911 is used to drive the screw rod 912 to rotate. Since the screw rod 912 of this embodiment is threadedly connected with the bracket 913, and the bracket 913 is fixedly connected with the connecting rod 92, when the first motor 911 drives the screw rod 912 to rotate, the bracket 913 will move horizontally along the screw rod 912 to drive the connecting rod 92 to move horizontally.

[0045] In some preferred embodiments, the fourth port 12 is fixedly provided with a mounting seat 13, the mounting seat 13 is slidingly connected with the connecting rod 92, and the steam switching device for the steam-baking integrated oven further comprises a second sealing assembly arranged between the mounting seat 13 and the fourth port 12. The second sealing assembly of this embodiment is preferably a sealing ring. Since this embodiment is arranged with the second sealing assembly between the mounting seat 13 and the fourth port 12, it can effectively avoid the situation that the steam formed by the evaporation of the liquid water in the boiler 2 leaks through the gap between the mounting seat 13 and the fourth port 12 and the water vapor entering the inner container 1 is insufficient.

[0046] As can be seen from the above, the steam switching device for the steam and baking integrated box provided in the application can realize the conduction or interruption of the boiler 2 and the inner container 1 by driving the sealing mechanism 8 to slide in the multi-way pipe 4 towards or away from the first port 5, so that when the food is baked, the water vapor formed by the evaporation of the liquid water in the boiler 2 can be prevented from entering the inner container 1 by interrupting the boiler 2 and the inner container 1, thereby effectively avoiding the problem of insufficient crispness of the food caused by the water vapor formed by the evaporation of the liquid water in the boiler 2 entering the inner container 1, and further effectively improving the eating experience of the food.
