When the pressing portion 133 is stressed, the elastic sheet deforms, and the blocking portion 132 moves along with the elastic sheet.

Or, in another embodiment, the first limiting device 13 includes an elastic sheet, and the pressing portion 133 and the first fixing portion 131 are both part of the elastic sheet. The blocking portion 132 is a component directly or indirectly disposed on the elastic sheet. The first fixing portion 131 is disposed on the device body 11, and when an operator does not apply a force to the pressing portion 133, the blocking portion 132 is located at a position for blocking the movement of the key 12. When the key 12 is pressed, the elastic sheet is elastically deformed, and the blocking portion 132 moves to release the blocking effect on the key 12.

Further, the first position-limiting device 13 may be a plate, a rod or other shaped element, and is not limited herein.

Specifically, if the first stopper 13 is a plate, the plate is elastically deformed and bent when a force is applied to a local portion of the plate due to a small thickness of the plate, and the area near the portion to which the force is applied is also adaptively displaced. If the first position-limiting device 13 is a rod, an acting force perpendicular to the length direction of the rod is applied to one end of the rod, and the rod can be elastically deformed and bent.

The first fixing portion 131, which is a part of the first position limiting device 13, is fixed on the device body 11, and the blocking portion 132 and the pressing portion 133 are displaceable with respect to the device body 11. Therefore, when in use, the first limiting device 13 is deformed by pressing the pressing part 133, and the blocking part 132 moves to release the blocking effect on the key 12.

Specifically, as shown in fig. 2 to 7, in one embodiment, the first limiting device 13 includes a plate and a blocking portion 132 disposed on the plate, and the pressing portion 133 and the first fixing portion 131 are both part of the plate.

When a pressing force is applied to the pressing portion 133, the first stopper 13 is elastically deformed and bent, the pressing portion 133 of the first stopper 13 is displaced with respect to the first fixing portion 131, and the stopper 132 moves with respect to the key 12 along with the deformation of the first stopper 13, thereby releasing the stopper function of the key 12. Moreover, the pressing portion 133 is suspended outside the apparatus main body 11, so that the user can easily touch and press the pressing portion.

Further, as shown in fig. 2 to 5, the direction of the acting force when the pressing portion 133 is pressed is perpendicular to the first direction, so that when the first position-limiting device 13 is deformed due to the pressing, the blocking portion 132 moves relative to the key 12 in the direction perpendicular to the first direction until the blocking portion 132 is separated from the key 12.

For example, in one embodiment, the first direction is a front-to-back direction of the cooking apparatus 10, and a direction of a force when the pressing portion 133 is pressed is from top to bottom. As shown in fig. 4 and 5, when the pressing portion 133 is pressed, the blocking portion 132 moves downward and separates from the key 12.

Specifically, the direction of the force applied when pressing the pressing portion 133 can be adjusted according to the specific installation position of the first stopper 13.

Further, as shown in fig. 1 to 7, and fig. 14 and 15, in one embodiment, the blocking portion 132 is a bump structure.

Alternatively, as shown in fig. 8 to 13, the blocking portion 132 is a cylindrical structure. The axial direction of the stopper 132 is a direction of an urging force when the pressing portion 133 is pressed.

Further specifically, in one embodiment, the first limiting device 13 is an elastic plastic part or an elastic metal part. For example, the first position limiting device 13 may be an elastic steel plate.

Further, in one embodiment, as shown in fig. 4, 5, 7 and 11, the pressing portion 133 is provided with a slip-preventing mark 1331. The slip-preventing mark 1331 increases the friction of the pressing part 133 during pressing, thereby improving the pressing effect.

Further, in one embodiment, the opening of the cooking chamber faces the front of the apparatus body 11. As shown in fig. 1, 8, 12, and 14, the pressing portion 133 protrudes outside the front side surface of the apparatus main body 11. As shown in fig. 10 and 11, the pressing portion 133 protrudes outside the right side surface of the apparatus body 11. Alternatively, the pressing portion 133 may protrude outside the bottom side, the left side, or the top side of the apparatus main body 11.

Further, in one embodiment, as shown in fig. 4, 5 and 9, the blocking portion 132 is provided with a guiding inclined surface 1321, and when the key 12 is pressed down and the door 112 is opened, the guiding inclined surface 1321 faces the key 12.

When the pressing portion 133 is pressed to release the blocking portion 132 from blocking the key 12, the pressing force applied to the pressing portion 133 is removed when the key 12 is pressed, and the blocking portion 132 is reset. At this time, the key 12 may already be located behind the blocking portion 132, or the key 12 may interfere with the guiding inclined surface 1321 of the blocking portion 132. In any case, the guiding inclined surface 1321 faces the key 12, so the key 12 is reset by the reverse movement in the first direction under the action of the key reset spring 121, and synchronously presses and slides through the initial position of the guiding inclined surface 1321 for resetting.

Specifically, as shown in fig. 5, when the key 12 is pressed, the key 12 is located behind the blocking portion 132, and the guide slope 1321 faces the key 12. When the key 12 is reset, the key gradually presses against the inclined guide surface 1321 and gradually slides over the inclined guide surface 1321.

The guide slope 1321 is gradually inclined toward the pressing direction of the pressing part 133 in the first direction.

After the first limiting device 13 is pressed to be elastically deformed, the key 12 moves along the first direction to unlock the door 112. When the key 12 is in the unlocking state, after the acting force is cancelled, the first limiting device 13 is reset, the guide inclined surface 1321 faces the key 12, the key 12 is reset under the action of a key reset spring 121 such as a spring and the like and is abutted against the guide inclined surface 1321, and along with the gradual reset movement of the key 12, the blocking part 132 is gradually abutted and pressed to move until the key 12 passes over the blocking part 132. The guiding inclined plane 1321 is arranged to make the resetting of the key 12 smoother so that the next door opening process can be performed normally.

In another embodiment, as shown in fig. 14 and 15, the first position-limiting device 13 is located below the apparatus main body 11, and the first fixing portion 131 is connected to a bottom wall of the outer shell of the door body 112.

Further, as shown in fig. 12 and 13, the pressing part 133 is located at the right side of the control box 1111.

More specifically, in one embodiment, as shown in fig. 12 and 13, the control box 1111 is located at the right side of the door body 112. The first limiting device 13 is located on the right side of the control box 1111. The first fixing portion 131 is connected to the right side wall of the housing of the case 111, or the first fixing portion 131 is connected to the right side wall of the housing of the control box 1111.

At this time, the let-bit port 1112 of the control box 1111 is formed on the right side wall of the control box 1111.

As shown in fig. 1 to 15, the pressing portion 133 is disposed adjacent to the key 12, so that the user can complete the door opening process with one hand, thereby improving the convenience of operation.

Further, as shown in fig. 1 to 8, in an embodiment, the cooking apparatus 10 further includes a second limiting device 14, the second limiting device 14 is connected to the apparatus main body 11, the second limiting device 14 includes a first limiting portion 141, the first limiting portion 141 is located on a side of the first limiting device 13 away from the apparatus main body 11, and the pressing portion 133 and the first limiting portion 141 are arranged at an interval.

The pressing portion 133 can move only within an allowable range by the blocking action of the first stopper 141, and thus, the situation that the first stopper 13 loses its restoration capability due to an excessively large deformation amount in the case of transportation or the like can be avoided. If the first position-limiting device 13 loses the resetting capability, the blocking portion 132 cannot be reset to the position blocking the key 12, so that the first position-limiting device 13 loses the position-limiting function.

Further, in one embodiment, a distance between the pressing portion 133 and the first position-limiting portion 141 is L, a distance required for the blocking portion 132 to move when the blocking portion releases the blocking effect on the key 12 is S, and L is greater than or equal to S.
