[0030] <Embodiment 1>

[0031] This embodiment provides an oven, which has a box body 1 and a grill mechanism for an oven, the grill mechanism includes a grill 2, a support frame 3, a sliding assembly 4 and a locking assembly 5, the grill 2 is installed above the support frame 3, and is used to place objects to be baked, and the support frame 3 is used to install the grill 2 in the box body 1 of the oven. A sliding assembly 4 is arranged between the grill 2 and the support frame 3, so that the grill 2 can slide relative to the support frame 3, and the sliding assembly 4 has a support rail 41 and a grill rail 42, the support rail 41 is fixed on the support frame 3, the grill rail 42 is fixed on the grill 2, and the grill rail 42 and the support rail 41 form an inner and outer joint, so that the grill rail 42 can slide relative to the support rail 41. The support frame 3 includes a shelf 31 and a support sheet 32 ​​fixed on the shelf 31, the support sheet 32 ​​is symmetrically arranged at both ends of the shelf 31, the support sheet 32 ​​is L-shaped, and the support rail 41 is fixed on the side of the support sheet 32 ​​away from the box body 1. There are two sets of sliding components 4 and locking components 5 , which are symmetrically arranged on both sides of the grill 2 .

[0032] The locking assembly 5 is used to lock the support frame 3 on the box body 1 when the grill 2 is taken out. The locking assembly 5 has a locking piece and an unlocking piece 53, wherein the locking piece includes a fixing portion 51 and a locking portion 52, the fixing portion 51 is fixed on the support frame 3 or the supporting rail 41; the locking portion 52 can rotate relative to the fixing portion 51, and has a locking state in contact with the box body 1 and an unlocking state separated from the box body; the unlocking piece 53 is fixed on the grill rail 42 and moves with the grill rail 42, and acts on the locking portion 52 through movement to switch the locking portion 52 between the locked state and the unlocked state.

[0033] Specifically, in this embodiment, the lock assembly 5 also has an elastic portion (a torsion spring 54 is selected) disposed between the locking portion 52 and the fixing portion 51. Figures 2-6 As shown, the fixing portion 51 and the locking portion 52 are a split installation structure, and the main bodies of the fixing portion 51 and the locking portion 52 are both plate-shaped. The fixing portion 51 is directly fixed to the side of the support sheet 32 ​​facing the box body 1, and the fixing portion 51 is bent toward the side of the locking portion 52 to form an upper and lower installation platform 511. Correspondingly, the locking portion 52 is also bent toward the side of the fixing portion 51 to form an upper and lower installation platform 521. A rotating shaft 55 is inserted between the upper and lower installation platforms, and a torsion spring 54 is sleeved on the outer periphery of the rotating shaft 55, and the torsion spring 54 has two abutting ends 541 and 542, and the abutting end 541 abuts on the fixing portion 51, and the abutting end 542 abuts on the locking portion 52.

[0034] The locking part 52 has a locking portion 522 and an unlocking mating portion 523. The locking portion 522 is used to cooperate with the inner wall of the inner liner 1 of the box, and the unlocking mating portion 523 is used to cooperate with the unlocking member 53. The unlocking member 53 has a fixing portion 531 and an unlocking portion 532. The fixing portion 531 is fixed to the grill track 42, and the unlocking portion 532 cooperates with the unlocking mating portion 523.

[0035] As Figures 4-6 shown, the locking part 52 and the fixing part 51 are in an open state without the action of the unlocking member 53. At this time, the unlocking mating portion 523 is close to the inner end of the fixing part 51, and the locking portion 522 is separated from the outer end of the fixing part 51, forming a V-shaped structure. At this time, the locking portion 522 can abut against the inner wall of the inner liner 1 of the box to form a locked state.

[0036] As Figure 3 shown, when the unlocking portion 532 of the unlocking member 52 moves inward along with the grill track 42 into the gap between the unlocking mating portion 523 and the inner end of the fixing part 51, and the unlocking mating portion 523 abuts against the unlocking portion 523, according to the lever principle, the locking portion 522 will rotate towards the side where the fixing part 51 is located and separate from the inner wall of the inner liner 1 of the box. At this time, the locking part 52 will be in an unlocked state.

[0037] As Figure 5 shown, when the grill 2 needs to be taken out, the unlocking member 52 will move outward along with the grill track 42. Once it moves to the position where the unlocking mating portion 523 is separated from the unlocking portion 532, the locking portion 522 abuts against the inner wall of the inner liner 1 of the box, and the locking part 52 is in a locked state. At this time, the support frame 3 can be fixed relative to the inner liner 1 of the box to prevent the support frame 3 from being taken out together with the grill 2, while the grill 2 can be taken out separately.

[0038] In addition, in the locked state, the gap between the unlocking mating portion 523 and the inner end of the fixing part 51 in the height direction should be at least smaller than the thickness of the inner end of the unlocking portion 532 to ensure that during the sliding process of the unlocking member 52, the locking portion 522 can contact the unlocking mating portion 523 and push the locking part 52 to rotate.

[0039] As Figure 6 shown, the inner liner 1 of the box has a blocking portion 11 for blocking in front of the locking part 52 (specifically the locking portion 522) when the locking part 52 is in the locked state. The blocking portion 11 blocks the front side of the locking portion 522, which can further prevent the support frame 3 from being taken out. The inner liner 1 of the box also has a placing groove 12 that cooperates with the shelf 31 of the support frame 3. The support frame 3 is placed in the placing groove 12 through the shelf 31.

[0040] As Figure 6As shown, in order to further limit the shelf 31, the outer end of the shelf 31 has an upwardly protruding upper convex portion 33, and a downwardly protruding lower convex portion 13 is formed in the placement groove 12. The front side of the lower convex portion 13 is used to cooperate with the rear side of the upper convex portion 33, and the rear side of the lower convex portion 13 forms the blocking portion 11. One side of the locking portion 52 facing the lower convex portion 13 has an avoidance bevel 524 corresponding to the rear side of the lower convex portion 13. The inner end of the shelf 31 has an upwardly protruding limiting portion 34. The top height of the limiting portion 34 is higher than the bottom height of the lower convex portion 13, and the limiting portion 34 can further prevent the support frame 3 from being directly removed from the inner liner 1 of the box, further enhancing the structural stability.

[0041] To avoid scratching when the various parts of the structure come into contact, as Figures 2-5 shown, both the locking part 522 and the unlocking part 532 are bent at the edges so that the surfaces are smoother when in contact.

[0042] The blocking mechanism of this embodiment can prevent the user from taking out the support frame 3 together when taking out the grill 2 alone, enhancing safety. When the user wants to take out the support frame 3 together, insert the grill 2 into the support frame 3 to make the locking portion 52 in the unlocked state, and then act on the support frame 3 to take out the grill 2 and the support frame 3 along the placement groove 12 at the same time.

[0043] <Embodiment 2>

[0044] This embodiment is basically the same as the above Embodiment 1, and the difference is that: the locking piece in this embodiment is an integrally provided elastic piece with a V-shaped cross-section. The locking portion 52 and the fixing portion 51 are connected into one body, and the locking portion 52 has a protruding force-applying portion 525 above the connection. The fixing portion 51 is still fixed on the support frame 3, and the locking portion 52 still has a locking part 522 and an avoidance bevel 524 at the outer end. The unlocking and locking principles of this embodiment are the same as those of Embodiment 1 above. When the unlocking piece moves inward, it can gradually contact the force-applying portion 525. Since the elastic piece itself has elasticity, the locking portion 52 is pushed by the unlocking piece to rotate to form an unlocked state. After the unlocking piece moves outward and leaves the force-applying portion 525, under the driving force of the elastic force of the elastic piece itself, the locking portion 52 opens outward, and the locking part 522 can abut against the inner wall of the inner liner 1 of the box to form a locked state.

[0045] Since the elastic piece itself has elasticity, there is no need to additionally add a torsion spring structure as in Embodiment 1 in this embodiment, and the structure is simpler.

[0046] <Embodiment 3>

[0047] Based on the above-mentioned Embodiment 1 and Embodiment 2, in this embodiment, the support piece 32 is cancelled, and the support track 41 is directly fixed on the shelf 31. At this time, the fixing part 51 can be directly fixed on the side of the support track 41 facing the inner liner 1 of the box body.

[0048] The above embodiments are only preferred embodiments of the present invention, and do not limit the protection scope of the present invention accordingly. Therefore, all equivalent changes made according to the structure, shape and principle of the present invention should be covered within the protection scope of the present invention.
