[0002] The existing steaming cooking equipment (such as steaming oven, steaming and baking integrated machine, etc.) generally has a wind deflector arranged above the liner, which forms an exhaust passage with the upper mounting plate, and the liner is communicated with the exhaust passage through an exhaust pipe. For example, the steaming and baking integrated machine of Chinese patent application No. CN202011069095.4 (publication No. CN112205887A) and the steaming oven disclosed in Chinese patent No. ZL202010324721.3 (authorized publication No. CN111557587A).

[0003] The exhaust pipe in the existing steaming cooking equipment is generally in a constant open state, that is, the liner is communicated with the exhaust passage through the exhaust pipe regardless of whether the machine is in working state.

A water tank assembly 10 and an air deflector 3 are arranged on the upper surface of the upper mounting plate 2, respectively. The water tank assembly 10 comprises a water tank 101 and a water tank seat 102 for accommodating the water tank 101, and the water tank seat 102 has an opening for the water tank 101 to enter and exit. The water tank 101 is connected to the water tank seat 102 in a relative sliding manner and can extend out of the opening of the water tank seat 102. The air deflector 3 is arranged on the upper mounting plate 2 to form an exhaust passage 30, and the exhaust passage 30 has an air inlet 32. The air inlet 32 is connected to an exhaust port 11 arranged on the top wall of the inner container 1 through an exhaust pipe 5.

[0032] Specifically, the air inlet 32 is arranged on the air deflector 3, and the exhaust pipe 5 is arranged on the upper mounting plate 2 in an up-down manner. The upper end of the exhaust pipe 5 is connected to the air inlet 32, and the lower end of the exhaust pipe 5 penetrates the gap between the upper mounting plate 2 and the top surface of the inner container 1 and is connected to the exhaust port 11 on the inner container 1. In this embodiment, the exhaust pipe 5 is arranged in this way to better form a clamping section 51 clamped by a clamp 6, thereby facilitating the open-close control of the clamp 6 on the exhaust pipe 5. Preferably, an exhaust fan 4 is arranged on the air inlet of the exhaust passage 30. The air deflector 3 is arranged in a front-rear direction. The exhaust fan 4 comprises a volute cover 31 formed by extending the rear end of the air deflector 3 rearward and a centrifugal impeller 41. The volute cover 31 is arranged on the upper surface of the upper mounting plate 2 to form a volute cavity 310. The centrifugal impeller 41 is arranged in the volute cavity 310, and the air inlet 32 is arranged on the volute cover 31. The steam discharged can be quickly discharged through the exhaust passage 30 under the action of the air flow of the centrifugal impeller 41.

[0033] Further, the steam cooking liner structure further comprises a control member and a linkage mechanism linking the control member and the water tank 101, and when the water tank 101 is moved out to the position, the control member controls the exhaust pipe 5 to be disconnected, and when the water tank 101 is moved in to the position, the control member controls the exhaust pipe 5 to be connected. The control member can have various specific implementations, for example, a control valve is arranged on the exhaust pipe 5 to control the connection and disconnection of the exhaust pipe 5, and the action of the control valve is linked to the water tank 101 through the linkage mechanism.

When the water tank 101 is moved out to the position, the clamp 6 clamps the exhaust pipe 5, which can prevent the hot gas in the liner 1 from being discharged, thereby playing a role in keeping the liner 1 and the food in the liner 1 warm, avoiding the food from being cooled during the water adding process and affecting the cooking effect, and improving the cooking efficiency because the liner 1 does not need to be heated again when cooking again after adding water. In addition, in the cooking state (the water tank 101 is moved in to the position), the clamp 6 releases the exhaust pipe 5, the exhaust pipe 5 is connected, and the gas in the liner 1 can be smoothly discharged into the exhaust passage 30 through the exhaust port 11 and the air inlet 32, thereby ensuring the normal cooking.

When the water tank 101 moves, the connecting frame 7 is driven, and the connecting frame 7 drives the first clamping body 61 and the second clamping body 63 through the first transmission assembly 8 and the second transmission assembly 9 respectively, so that the first clamping body 61 and the second clamping body 63 move towards or away from each other.

[0037] Specifically, the first transmission assembly 8 comprises a first linkage 81, a first transmission gear 82 and a first transmission rack 83 fixed on the first clamping body 61 along the moving direction of the first clamping body 61, the first transmission gear 82 is engaged with the first transmission rack 83, and the first transmission gear 82 is installed on one end of the first linkage 81, and the other end of the first linkage 81 is pivoted with the connecting frame 7.

When the water tank 101 drives the connecting frame 7, the corresponding transmission gears are driven to rotate through the respective linkages, thereby driving the corresponding transmission racks to move through the respective transmission gears, and finally realizing the actions of the clamping bodies, so that the first clamping body 61 and the second clamping body 63 move towards each other when the water tank 101 moves out, and the first clamping body 61 and the second clamping body 63 move away from each other when the water tank 101 moves in. The connecting frame 7 comprises a first connecting rod 71 and a second connecting rod 72 arranged in a direction perpendicular to the first connecting rod 71, one end of the first connecting rod 71 is fixed with the water tank 101, the middle part of the second connecting rod 72 is fixed on the other end of the first connecting rod 71, and the two ends of the second connecting rod 72 are respectively fixed with a first pivot shaft 721 and a second pivot shaft 722, the first linkage 81 comprises a first linkage 811 and a second linkage 812, one end of the first linkage 811 is connected with the first pivot shaft 721 and the other end is pivoted with one end of the second linkage 812, and the other end of the second linkage 812 is installed with the first transmission gear 82, the second linkage 91 comprises a third linkage 911 and a fourth linkage 912, one end of the third linkage 911 is connected with the second pivot shaft 722 and the other end is pivoted with one end of the fourth linkage 912, and the other end of the fourth linkage 912 is installed with the second transmission gear 92. In this way, the forward and backward movement of the water tank 101 can be more smoothly transmitted to the respective linkage structures, and the respective clamping bodies are driven to move through the engagement of the respective transmission gears with the corresponding racks.

[0038] Preferably, the first transmission assembly 8 and the second transmission assembly 9 are symmetrically arranged at the two ends of the second connecting rod 72 with the first connecting rod 71 as the center. Thus, the actions of the water tank 101 can be uniformly transmitted to the respective first clamping bodies 61, thereby realizing the stable clamping and loosening of the exhaust pipe 5 by the clamp 6, and ensuring the stability and reliability of the open and close control of the exhaust pipe 5.

[0039] In the embodiment, the linkage mechanism is arranged at the rear side of the water tank assembly 10, the first connecting rod 71 extends in the front-rear direction, the front end of the first connecting rod 71 is connected with the tail end of the water tank 101 by penetrating through the window 1021 arranged at the tail end of the water tank seat 102, the second connecting rod 72 is connected with the rear end of the first connecting rod 71 in the left-right direction, the first transmission rack 83 and the second transmission rack 93 extend in the left-right direction respectively, the exhaust pipe 5 comprises the clamping section 51 extending vertically behind the water tank assembly 10, and the first clamping body 61 and the second clamping body 63 are arranged at the left and right sides of the clamping section 51 of the exhaust pipe 5 respectively.

[0040] Further, preferably, in the embodiment, each of the clamping bodies comprises a mounting strip 63 extending in the left-right direction and a clamping head 64 fixed at the inner end of each mounting strip 63, and the two clamping heads 64 are arranged at the left and right sides of the clamping section 51 of the exhaust pipe 5 respectively, and each transmission rack is fixed on the corresponding mounting strip 63 in the length direction. The clamping head 64 can make the clamp 6 clamp the exhaust pipe 5 better, and the transmission rack can be arranged on the corresponding clamping body more stably. In addition, the first clamping plate 6a, the second clamping plate 6b and the mounting plate 6c are further included, the first clamping plate 6a and the second clamping plate 6b are arranged horizontally respectively, and the front end of each clamping plate is provided with a corresponding transmission rack and the rear end is provided with a corresponding clamping body, the mounting plate 6c is vertically fixed on the upper surface of the upper mounting plate 2 in the left-right direction and is arranged below the first clamping plate 6a and the second clamping plate 6b, and the lower surface of each clamping plate is detachably connected with the top end of the mounting plate 6c. On the one hand, the first clamping body 61 and the second clamping body 63 can be arranged stably, and on the other hand, the transmission rack can be arranged on the corresponding clamping body (each transmission rack and the corresponding clamping body are an integral part) further stably, so as to improve the reliability of the linkage between the connecting frame 7 and each clamping body.

[0042] In addition, the detachable connection between the connecting frame 7 and the water tank 101 can have various specific implementations. Preferably, the connecting frame 7 and the water tank 101 are magnetically connected, which is simple in structure and facilitates the user to take out or put into the water tank seat 102 in the water tank 101. Specifically, in the embodiment, the front end of the first connecting rod 71 is fixed with a first magnet (not shown), and the tail end of the water tank 101 is fixed with a second magnet (not shown). In the installed state of the water tank 101, the first magnet and the second magnet are detachably connected, and the water tank 101 can be taken out by pulling it forward along the water tank seat 102 to separate the first magnet from the second magnet.

[0043] The working process of the present application is as follows:

The forward movement of the first connecting rod 71 drives the first connecting rod 811 to rotate clockwise (in the top view state, the same below), the first connecting rod 811 drives the second connecting rod 812 to rotate clockwise, the second connecting rod 812 drives the first transmission gear 82 to rotate clockwise, and then the first clamping body 61 moves to the right. Similarly, the movement direction of the second transmission assembly 9 and the second clamping body 63 is opposite to that of the first transmission assembly 8 and the first clamping body 61, so that the first clamping body 61 and the second clamping body 63 move towards each other to clamp the exhaust pipe 5. At this time, in the process of the user taking out the water tank 101 to add water, the steam in the inner container 1 cannot be discharged through the exhaust passage 30, avoiding the rapid drop of the temperature inside the inner container 1 and improving the efficiency of steam cooking.

[0045] When the user pushes the water tank 101 into the water tank seat 102, the water tank 101 drives the first connecting rod 71 to move backward, the movement of the first connecting rod 71 drives the third connecting rod 911 to rotate counterclockwise, the third connecting rod 911 drives the fourth connecting rod 912 to rotate counterclockwise, the fourth connecting rod 912 drives the second transmission gear 92 to rotate counterclockwise, and then the second clamping body 63 moves to the left. Similarly, the movement direction of the first transmission assembly 8 and the first clamping body 61 is opposite to that of the second transmission assembly 9 and the second clamping body 63, so that the first clamping body 61 and the second clamping body 63 move away from each other to release the exhaust pipe 5. The water in the water tank 101 flows into the inner container 1 to generate fresh steam, and at the same time, the excess steam is discharged to the exhaust passage 30 through the exhaust pipe 5, achieving dynamic balance.
