Description

TECHNICAL FIELD

[0001] The utility model relates to kitchen equipment field especially, and it relates to a cooking device. BACKGROUND

[0002] The cooking device can include a box shell and an inner container, and a cavity can be formed in the inner container. The cooking device can include a heating pipe that can heat the air in the cavity of the inner container and complete the cooking function of roasting. Proteins, fats and other carbohydrates in food can easily produce oil fume when heated to the smoke point. Different foods have different abilities to produce oil fume due to different materials. Under the same conditions, meat produces more oil fume, while vegetable food produces less oil fume.

[0003] In the prior art, to exhaust the oil fume in the inner container, an oil fume exhaust system is generally installed outside the inner container. The oil fume exhaust system mainly includes a fan and a filter module. The fan is arranged outside the inner container, and an exhaust hole is formed in the side wall of the inner container, so that the air inlet of the fan is in communication with the exhaust hole, and the air outlet of the fan is in communication with the filter module. Under the action of the fan, the oil fume is exhausted after being filtered.

[0004] However, if the inner container is always in communication with the fan, the oil fume will continue to be exhausted to the fan, and the heat in the inner container will continue to leak out, which can affect the cooking process and the maturity and taste of the food. Some cooking devices are provided with an on-off structure to communicate the fan and the inner cavity of the inner container, but it is difficult to accurately control the degree of communication between the fan and the inner cavity of the inner container. When the degree of communication is too large, the heat in the cooking cavity is lost too much, and when the degree of communication is too small, too much oil fume is produced in the cooking cavity, which is not conducive to the cooking of healthy food. In addition, the connecting structure is prone to deformation during movement and is not smooth in movement. Therefore, the present application proposes a cooking device. SUMMARY

[0110] In the present application, reference is made to Figures 5-8The on-off mechanism 4 can include a driving member 43. The driving member 43 can include a first shaft 431. The first shaft has an initial position. The first shaft has an extended position. When the first shaft is in the initial position, the shielding member is in the closed position. When the first shaft is in the extended position, the shielding member is in the open position.

[0111] When the first shaft is switched from the initial position to the extended position, the first shaft 431 moves in the first direction, the first shaft pushes the third segment of the lever to rotate the second segment of the lever and the first segment of the lever relative to the first support part, the first segment of the lever drives the shielding member to rotate through the first connecting member to switch the shielding member from the closed position to the open position.

[0112] By setting the on-off mechanism to include the shielding member, the first lever, the first connecting member and the driving member, the movement of the first shaft can be converted into the rotation of the shielding member, the shielding member is not easy to deform, the on-off mechanism is not easy to jam, the on-off mechanism is not easy to interfere with other structures, the communication and isolation of the cooking cavity and the smoke exhaust cavity can be smoothly controlled, the rotation angle of the shielding member can be accurately controlled through the extension length of the first shaft, the communication degree of the cooking cavity and the smoke exhaust cavity can be accurately controlled, the communication degree can be set as required, the cooking effect is avoided due to excessive communication, and the cooking cavity is avoided due to small communication degree, so that the oil smoke in the cooking cavity is more, and the food health cooking is ensured.

[0113] In the present application, when the first shaft moves in the first direction, the first shaft pushes the third segment of the lever to rotate the second segment of the lever and the first segment of the lever relative to the first support part, the first segment of the lever drives the shielding member to rotate through the first connecting member to switch the shielding member from the closed position to the open position.

[0114] In the present application, the driving member can be a second motor. The second motor can include a first shaft. The second motor is powered to move the first shaft in the first direction.

[0115] The second motor can be a wax motor. The working principle of the wax motor is to convert heat energy into mechanical energy by using the volume expansion generated by the solid-liquid change process of the temperature-sensitive wax through heating.

[0116] When the conductive springs at both ends of the wax motor actuator are connected to the power supply, the heating fins on the internal wax motor start to heat. The temperature-sensitive wax inside the wax motor melts, and the volume expansion generated during the melting process pushes the piston top rod inside the wax motor to move outward. The piston top rod is the first shaft. When the conductive springs at both ends of the wax motor actuator are disconnected from the power supply, the heating fins on the wax motor do not heat. The volume contraction generated by the continuous cooling and solidification of the temperature-sensitive wax helps the piston top rod to return to the initial position under certain external force.

[0117] In the present application, the first stress part 42231 can be formed on the third segment of the lever. When the first shaft pushes the third segment of the lever, the first shaft acts on the first stress part. The first stress part can be a groove. When the first shaft pushes the third segment of the lever, the first shaft is inserted into the first stress part. This can avoid the first shaft and the third segment of the lever from being misaligned when the first shaft acts on the third segment of the lever, and ensure that the shielding member rotates normally.

[0118] In the present application, referring to Figures 5-8 , the on-off mechanism 4 can include a first torsional spring 423. When the shielding member is switched from the closed position to the open position, the first shaft moves in the first direction, and the shielding member twists the first torsional spring. When the shielding member is switched from the open position to the closed position, the first torsional spring drives the shielding member to rotate, and the shielding member can drive the first lever to rotate relative to the first support part through the first connecting piece, and the first lever drives the first shaft to move in the opposite direction of the first direction to switch the first shaft from the extended position to the initial position.

[0119] By providing the first torsional spring, the shielding member can be reset, the structure is simple, and the setting of other separate and complex reset mechanisms is avoided. The first shaft can be reset through the first connecting piece and the first lever, and the on-off mechanism can work reciprocatingly.

[0120] In the present application, referring to Figures 5-8 , the inner container 2 is formed with a smoke exhaust hole 22. When the shielding member is in the closed position, the shielding member closes the smoke exhaust hole.
