Based on the above structure, a through hole (not shown) is provided in the cavity back plate 102, and the link 507 is penetrated in the through hole. Specifically, a cavity is formed between the cavity back plate 102 and a housing (not shown) of the cooking appliance, and a rear end of the link 507, the return spring 506, and the micro switch 508 are all located in the cavity. The through hole is buckled with an inner sealing ring 502 as a first sealing structure for steam/oil gas leakage. The inner sealing ring 502 is provided with a convex hull 5021 with elastic deformation capability, and the head end of the connecting rod 507 passes through the through hole and then is positioned in the convex hull 5021. When the baffle plate assembly 2 is installed, the triggering structure is extruded on the convex hull 5021, the convex hull 5021 is stressed to deform, and the connecting rod 507 is pushed to move backwards along the axial direction until the connecting rod 507 abuts against the micro switch 508.

The specific structure of the convex hull 5021 is not limited, and it is only necessary to have elastic deformation capability. Preferably, the convex hull 5021 can be made of a high temperature resistant flexible material or a corrugated metallic material. The installation mode of the inner seal ring 502 is not limited, in this embodiment, the inner seal ring 502 is pressed on the cavity back plate 102 by the inner pressure plate 501 and is fixedly connected, the disassembly and the assembly are convenient, and the connection structure is stable.

On the basis of the above structure, the cooking appliance further includes a spring top plate 504, the spring top plate 504 is disposed outside the through hole, one end of the return spring 506 is abutted on a limit rib (not shown) of the link 507, and the other end of the return spring 506 is abutted on the spring top plate 504. The connecting rod 507 can play a supporting and limiting role on the return spring 506, and the return spring 506 is prevented from being bent along the radial direction.

The cooking utensil further comprises an outer pressing plate 505, wherein the outer pressing plate 505 is located on the outer side of the inner wall surface and sleeved on the connecting rod 507, and an outer sealing ring 503 is arranged between the outer pressing plate 505 and the inner wall surface and is used as a second sealing structure for steam/oil gas leakage. That is, the outer pressure plate 505 and the outer sealing ring 503 are both located in the cavity between the cavity back plate 102 and the outer casing of the cooking appliance. The outer seal ring 503 is preferably annular, and an inner ring of the outer seal ring 503 extends in an axial direction or a direction inclined relative to the axial direction to form a convex rib (not shown), and the convex rib abuts against the connecting rod 507.

As shown in fig. 1, 6 and 7, an upper cavity fan 20, an upper cavity fan cover plate (not shown), an upper cavity steam inlet 8, an upper cavity rear heating pipe (not shown) and an upper cavity temperature sensor (not shown) are arranged in the upper cavity 3; the lower cavity 4 is provided with a lower cavity fan 19, a lower cavity fan cover plate (not shown), a lower cavity steam inlet 9, a lower cavity rear heating pipe (not shown) and a lower cavity temperature sensor (not shown).

The cooking appliance further comprises a steam generator 10, a water-steam separation box 11, a Y-shaped three-way pipe 13, an upper cavity steam valve 14 and a lower cavity steam valve 16, wherein the steam generator 10 is connected to the Y-shaped three-way pipe 13 through the water-steam separation box 11, and the upper cavity steam valve 14 and the lower cavity steam valve 16 are respectively arranged on one outlet end of the Y-shaped three-way pipe 13. The upper cavity steam valve 14 is connected with the upper cavity steam inlet 8 through the upper cavity steam inlet pipe 15, the lower cavity steam valve 16 is connected with the lower cavity steam inlet 9 through the lower cavity steam inlet pipe 17, and the design of the Y-shaped three-way pipe 13 enables the upper cavity steam valve 14 and the lower cavity steam valve 16 to respectively control the air inlet of the upper cavity 3 and the lower cavity 4, so that the independent steam supply function of the upper cavity 3 and the lower cavity 4 is realized.

The upper cavity steam valve 14 and/or the lower cavity steam valve 16 comprises a steam inlet 161 and a steam outlet 162, and an included angle alpha between the axis of the steam inlet 161 and the axis of the steam outlet 162 is less than or equal to 90 degrees. When the upper cavity steam valve 14 or the lower cavity steam valve 16 is closed, because the included angle between the axis of the steam inlet 161 and the axis of the steam outlet 162 is smaller, condensed water cannot be accumulated at the steam inlet 161, and the condensed water can smoothly flow back into the water-vapor separation box 11, so that the condensed water is prevented from entering the cavity 1 when the steam valve is opened next time, water resources are saved, and the user experience is good. Compared with a T-shaped tee structure, the Y-shaped tee pipe 13 can further promote condensate to smoothly flow back to the water-vapor separation box 11, and the backflow effect is better.

In order to prevent steam generated by the steam generator 10 from impacting the water-steam separation box 11, a water-steam separation box connecting pipe 12 is connected between the steam generator 10 and the water-steam separation box 11, the water-steam separation box connecting pipe 12 is bent, and the bending angle of the water-steam separation box connecting pipe 12 is smaller than 90 degrees. The bent water-vapor separation box connecting pipe 12 can properly reduce the flow rate of steam and protect the use safety of the water-vapor separation box 11.

On the basis of the above structure, the steam generator 10 is connected to a water level control assembly (not shown) through a connection water pipe (not shown), and the water level control assembly is connected to the cavity through a pressure balance pipe (not shown) to ensure that the liquid level pressure of the water level control assembly is the same as the liquid level pressure of the steam generator 10; body temperature sensors (not shown) for sensing temperature are provided in the upper and lower chambers 3 and 4, respectively.

In order to completely separate the upper chamber 3 and the lower chamber 4, the diaphragm assembly 2 needs to have good sealability. In this embodiment, the diaphragm assembly 2 includes a diaphragm seal ring (not shown), an upper diaphragm (not shown) and a lower diaphragm (not shown), the upper and lower diaphragms being oppositely mounted to form a seal ring mounting groove in which the diaphragm seal ring is mounted. The baffle sealing ring is hollow, and ribs (not shown) in the sealing ring divide the hollow structure into a sealing ring upper cavity (not shown) and a sealing ring lower cavity (not shown). The outside of the baffle sealing ring is provided with a plurality of raised sealing ring external ribs (not shown); the part of the baffle sealing ring matched with the upper baffle is provided with a convex sealing ring inner rib (not shown) and a sealing ring dovetail rib (not shown); the part of the baffle sealing ring matched with the lower baffle is provided with a convex sealing ring lower inner rib (not shown) and a sealing ring lower dovetail rib (not shown). After the baffle plate assembly 2 is inserted into the cavity 1, the baffle plate sealing ring is tightly abutted on the cavity side plate 101 and the cavity rear plate 102, so that odor tainting and heat transfer between the upper cavity 3 and the lower cavity 4 are avoided; when the upper and lower chambers 3 and 4 perform the steaming cooking mode and the baking cooking mode, respectively, the partition plate assembly 2 can prevent steam from entering the baking area, and the use is more convenient.

Fig. 8 shows a basic operation flow of the cooking appliance.

When the partition board assembly 2 is inserted into the cavity 1, the partition board assembly 2 pushes the connecting rod 507 to trigger the micro switch 508, so that the control device operates the cavity separating function. Under the function of dividing the cavity, a user can independently select the upper cavity 3 or the lower cavity 4 as a working cavity, and can also let the upper cavity 3 or the lower cavity 4 serve as the working cavity.

When the cavity separating function is selected, if the user selects the upper cavity 3 as the working cavity, and simultaneously the steaming function is started, the steam generator 10 and the upper cavity steam valve 14 are opened, and the lower cavity steam valve 16 is closed, so that steam only passes through the upper cavity 3, and otherwise, only passes through the lower cavity 4.

If the user selects the upper cavity 3 and the lower cavity 4 to work simultaneously and the steaming function is started simultaneously, the steam generator 10, the upper cavity steam valve 14 and the lower cavity steam valve 16 are opened, when one of the upper cavity 3 or the lower cavity 4 reaches a set temperature, the corresponding steam valve is closed, and if both the two sub cavities reach the set temperature, the steam generator 10 and the two steam valves are closed, so that the separate supply of steam for each sub cavity is realized.

If one of the upper or lower chambers 3, 4 selects the steaming function and the other selects the conventional steaming function (not selecting the steaming function), the steam generator 10 is turned on and the corresponding steam valve is turned on, while the other chamber-separating steam valve, which does not need steam, is turned off to realize the combination of the chamber-separating steaming and baking functions.

Of course, the identification component 5 is not needed in the cooking appliance, and after the user inserts the partition board component 2 into the cavity 1, the user selects the cavity separating function in the control interface by himself. In addition, only one steam valve can be arranged, namely, one of the sub-cavities is directly communicated with steam, and the other one of the sub-cavities is controlled by the steam valve, so that when the cooking utensil operates the steaming function, one of the sub-cavities has the steaming function, and the other sub-cavity opens the steam valve according to the requirement.
