The present embodiments provide a cooking device, including but not limited to an electric oven and an electric steaming oven, and other cooking devices using high temperature for processing food are also within the scope of protection. As shown in fig. 1 to 4, the cooking device comprises a box body 1 and a movable baffle 2, wherein an exhaust channel is formed on the box body 1, and the exhaust channel communicates a cooking chamber in the box body 1 to the outside of the box body 1; the flapper 2 is configured to be able to change position in the horizontal direction to open the exhaust passage or at least partially block the exhaust passage.

In the temperature rise stage of the cooking device, the movable baffle 2 blocks the exhaust passage, so that the air in the cooking chamber can be quickly heated, and the food cooking efficiency is improved; when food needs to be taken out after cooking is finished, the movable baffle 2 opens the exhaust channel, hot air in the cooking cavity can be quickly exhausted, and a user is prevented from being scalded due to the hot air gushing out when the door is opened; in the culinary art process, can adjust the position of adjustable fender 2 as required, make the exhaust passage partially open, can let out partial steam or oil smoke, can avoid the excessive loss of heat in the culinary art cavity again, shortened the required time of culinary art on the basis of guaranteeing safety, it is more convenient to use.

The exhaust passage of the cooking device can be designed to be wider, and the effective width of the exhaust passage can be adjusted by adjusting the position of the movable baffle. By effective width is meant the gap between the edge of the flapper 2 and the edge of the exhaust passage, from which gap the fumes and hot gases can only escape. When oil smoke and hot gas need to be discharged, the movable baffle opens the exhaust channel, the effective width value of the exhaust channel is larger, and the discharge speed of the oil smoke and the hot gas is high; when oil smoke and hot gas do not need to be discharged, the movable baffle at least partially shields the exhaust channel, the effective width value of the exhaust channel is smaller or completely closed, the temperature rise speed in the cooking cavity is high, and the cooking efficiency is high.

The exhaust passage includes an outer passage 31 and an inner passage 32, and the outer passage 31 and the inner passage 32 communicate with each other through a louver 34. One end of the outer channel 31 is an air outlet port 35 for discharging hot air to the outside, and the other end is provided with a fan 33, and the fan 33 blows air towards the direction of the air outlet port 35. The inner passage 32 is communicated to the cooking chamber, and hot air and oil smoke in the cooking chamber can enter the outer passage 31 through the inner passage 32. The heat dissipation holes 34 are located between the fan 33 and the air outlet port 35 of the outer channel 31, the airflow generated by the fan 33 passes through the heat dissipation holes 34 before reaching the air outlet port 35, and negative pressure is formed at the heat dissipation holes 34 by the airflow, so that the hot air and the oil smoke in the inner channel 32 are taken away together. The arrows in fig. 3 and 4 indicate the direction of flow of the air flow.

The specific shape and structure of the outer passage 31 are not limited, and the air flow can be allowed to flow smoothly. In the present embodiment, the outer passage 31 is defined by a cover plate (not shown) located above and a bottom plate (not shown) located below. The outer channel 31 is transversely arranged, so that the idle space of the box body 1 is fully utilized, and the volume of the box body 1 cannot be obviously increased.

The specific shape and structure of the inner passage 32 are not limited, and the hot air and the soot in the cooking chamber can be exhausted to the outer passage 31. In order to avoid too fast heat loss in the cooking cavity, the inner channel 32 comprises a section of transverse pipe and a section of inner container exhaust pipe 38 which is longitudinally arranged, hot air and oil smoke enter the transverse pipe after turning about 90 degrees after entering the inner container exhaust pipe 38, and then enter the outer channel 31 from the heat dissipation hole 34 at the top of the transverse pipe, and the turning structure can reduce the flow speed of the hot air, so that the heat loss in the cooking cavity is reduced, and the cooking efficiency of food is improved.

As shown in fig. 2 and 4, the heat dissipating holes 34 are provided with a wind shielding sloping plate 36, the wind shielding sloping plate 36 is located in the outer channel 31 and on one side of the heat dissipating holes 34 close to the fan 33, and the wind shielding sloping plate 36 extends along the blowing direction of the fan 33. When the airflow generated by the fan 33 flows through the heat dissipation holes 34, the airflow needs to climb along the back surface of the wind shielding sloping plate 36 until the airflow crosses the top edge of the wind shielding sloping plate 36. The air flow does not descend linearly after turning over the wind-shielding sloping plate 36, but descends slowly along an arc line until part of the air flow approaches or clings to the bottom surface of the outer channel 31. At this moment, the airflow has already advanced for a certain distance and has already passed the heat dissipation hole 34 when approaching or adhering to the bottom surface of the outer channel 31, so as to prevent the airflow from directly flowing into the inner channel 32 from the heat dissipation hole 34 and avoid rapid cooling in the cooking chamber.

The specific moving manner of the movable baffle 2 is not limited, and the position can be changed in the horizontal direction as required to open the exhaust passage or at least partially shield the exhaust passage. As shown in fig. 1 to 4, in the first mode, the cooking apparatus further includes a synchronous motor 4 and a rotation connecting shaft 51, one end of the rotation connecting shaft 51 is connected to an output end of the synchronous motor 4, and the other end is connected to the movable baffle 2. When the output end of the synchronous motor 4 rotates, the output end can drive the rotating connecting shaft 51 to rotate, so that the movable baffle 2 rotates, and the opening and closing of the exhaust channel are realized.

The position of the movable baffle 2 in the exhaust passage is not limited, and the movable baffle can be opened or at least partially block the exhaust passage. Preferably, the exhaust passage comprises a heat dissipating port 37, the heat dissipating port 37 being located in the cooking chamber, and the movable baffle 2 being disposed in the cooking chamber and attached to the heat dissipating port 37.

The rotating connecting shaft 51 is eccentrically disposed with respect to the heat dissipating port 37, and when the rotating connecting shaft 51 rotates to a first position, the body of the flapper 2 is shielded on the heat dissipating port 37, and when the rotating connecting shaft 51 rotates to a second position, the body of the flapper 2 rotates away from the heat dissipating port 37. The axis of the rotary connecting shaft 51 and the center of the heat dissipation port 37 are arranged in a staggered manner, and the movable baffle plate 2 can open the exhaust channel or at least partially shield the exhaust channel through rotation, so that the use is convenient, and the opening and closing speed of the heat dissipation port 37 is high.

As shown in fig. 5, in the second mode, the cooking apparatus further includes a traverse driving device 6 and a traverse connecting shaft 52, and one end of the traverse connecting shaft 52 is connected to an output end of the traverse driving device 6 and the other end is connected to the flapper 2. The traverse driving device 6 may be, but is not limited to, an air cylinder or a hydraulic cylinder, and an output end thereof is capable of extending and contracting in the axial direction. The traverse driving device 6 is arranged along the radial direction of the heat dissipation port 37, and the output end of the traverse driving device drives the movable baffle 2 to move along the radial direction of the heat dissipation port 37 through the traverse connecting shaft 52, as shown by a straight line with a double-headed arrow in fig. 5, so as to realize the opening and closing of the heat dissipation port 37. Fig. 5 shows a state in which the heat radiation port 37 is partially opened.

In order to prevent the shutter 2 from deviating from the heat radiation port 37, the cooking apparatus further includes a stopper rail (not shown) along which the traverse connecting shaft 52 can move. The moving state of the movable baffle 2 is more stable, so that a gap between the movable baffle 2 and the heat dissipation port 37 caused by the deviation of the transverse moving connecting shaft 52 is avoided, and the accidental loss of heat in the cooking cavity is avoided.

If the axis of the traverse connecting shaft 52 coincides with the center of the movable baffle 2, when the traverse connecting shaft 52 abuts against the edge of the heat dissipation port 37, half of the area of the movable baffle 2 is still shielded on the heat dissipation port 37, which is not beneficial to quickly discharging hot air and oil smoke. To solve this problem, the axis of the traverse link shaft 52 is offset from the center of the flapper 2, and preferably, the traverse link shaft 52 is connected at a position close to the edge of the flapper 2. The traverse connecting shaft 52 is moved radially from the edge of the radiation port 37 to the edge of the opposite side, and the shutter 2 can open the radiation port 37 as much as possible from completely covering the radiation port 37.

On the basis of the above structure, as shown in fig. 1 and 3, the cooking apparatus further includes a temperature sensor 8 for detecting the temperature in the cooking chamber and a smoke sensor 9 for detecting the smoke concentration in the cooking chamber.

When a heating pipe (not shown) of the cooking device starts to work, the temperature in the cooking cavity is not high, no oil smoke is generated, the movable baffle 2 completely shields the exhaust channel, and all heat is left in the cooking cavity. The cooking device has high temperature rise speed, and reduces the waiting time of a user.

The heating pipe continues to heat, the temperature in the cooking chamber continuously increases, and if meat and the like are processed, oil smoke begins to be generated. The temperature sensor 8 detects the temperature in the cooking chamber, and the oil smoke sensor 9 detects the oil smoke contamination degree in the cooking chamber. If the temperature in the cooking chamber reaches a set value, the heating pipe stops heating, otherwise, the heating is continued.

When the oil smoke pollution degree in the cooking chamber reaches a first set value, the synchronous motor 4 (or the transverse moving driving device 6) drives the movable baffle 2 to rotate (or move), and an exhaust channel is opened. The fan 33 is activated to generate an air flow in the outer passage 31, and a negative pressure is generated at the heat dissipation hole 34. Hot air and soot in the cooking chamber enter the outer passage 31 through the inner passage 32 until being discharged out of the cabinet 1.

When the oil smoke pollution degree in the cooking cavity is reduced to a second set value (the second set value is smaller than the first set value), the synchronous motor 4 (or the transverse moving driving device 6) drives the movable baffle 2 to rotate reversely (or move reversely), an exhaust channel is shielded, heat loss in the cooking cavity is reduced, and energy conservation and emission reduction are achieved.

After cooking or in a set time before cooking, the synchronous motor 4 (or the traverse driving device 6) drives the movable baffle 2 to rotate (or move), so that the exhaust passage is opened, and hot air in the cooking chamber is exhausted from the inner passage 32 and the outer passage 31. Thereby guarantee that the user can not have a large amount of steam to gush out from the culinary art cavity when opening the door and take out food, avoid taking place the scald accident. Can set up automatic lock on cooking device's door, close automatic lock before the steam in the culinary art cavity is not basically discharged, cooking device's door can't be opened, avoids being scalded because the user opens the door earlier.

It should be noted that the foregoing is only a preferred embodiment of the present invention and the technical principles applied. It will be understood by those skilled in the art that the present invention is not limited to the particular embodiments described herein, but is capable of various obvious modifications, rearrangements and substitutions as will now become apparent to those skilled in the art without departing from the scope of the invention. Therefore, although the present invention has been described in greater detail with reference to the above embodiments, the present invention is not limited to the above embodiments, and may include other equivalent embodiments without departing from the scope of the present invention.
