As shown in fig. 1, an embodiment of the present invention provides an oven, which includes a case 1 and a frying and baking plate 2 detachably provided in an inner cavity 11 of the case 1. The door assembly 10 for opening or closing the inner cavity 11 is arranged on the box body 1, the first heating element 12 is arranged on the top of the inner cavity 11, the third heating element 13 is arranged on the bottom of the inner cavity, and when the frying and baking plate 2 is placed in the inner cavity 11, the frying and baking plate 2 is heated through the first heating element 12 and the third heating element 13. However, in some ovens, the frying plate 2 is usually placed close to the top of the cavity, so that the third heating element 13 is far from the bottom surface of the frying plate 2, and the bottom surface of the frying plate 2 cannot be heated well.

To solve the above-described problem, the oven of the present embodiment further includes a second heating member 14 rotatably provided in the inner cavity 11 and having a first position and a second position in a rotation direction.

When the frying plate 2 is at the first position, the second heating element 14 is in a folded state which is attached to or close to the rear side wall of the inner cavity 11.

When the frying plate 2 is in the second position, the second heating member 14 is in an expanded state at least partially moved under the frying plate 2 to heat the bottom surface of the frying plate 2.

The oven of the embodiment further comprises a linkage mechanism 5, wherein the linkage mechanism 5 is arranged on the oven body 1 and is connected with the second heating element 14. The frying and roasting plate 2 can trigger the linkage mechanism 5 and drive the second heating element 14 to rotate through the linkage mechanism 5 so as to enable the second heating element 14 to be switched between the first position and the second position, as shown in fig. 8 (a) to 8 (b).

Specifically, when the frying and baking plate 2 is used for frying and baking food, the linkage mechanism 5 can be triggered by the frying and baking plate 2, so that the second heating element 14 rotates from the first position to the second position, the first heating element 12 and the second heating element 14 are started at the moment respectively, the first heating element 12 heats the front surface of the frying and baking plate 2, and the second heating element 14 heats the bottom surface of the frying and baking plate 2, and therefore the front heat and the bottom surface heat of the frying and baking plate are pulled close, and the frying and baking uniformity and the frying and baking efficiency can be improved. When the food needs to be heated by other appliances (the chicken fork 3 or the frying basket 4), the second heating element 14 can be rotated from the second position to the first position, so that the heating elements are arranged on the top, the bottom and the back wall surface of the inner cavity 11, and the heating efficiency can be improved and the baking color is more uniform when the frying and baking plate 2, the chicken fork 3 or the frying basket 4 is heated.

The rotatable second heating element 14 and the linkage mechanism 5 for driving the second heating element 14 to rotate are arranged in the oven, when the frying and baking plate 2 is heated, the frying and baking plate 2 can trigger the linkage mechanism 5 to drive the second heating element 14 to rotate so that at least part of the second heating element moves to the lower side of the frying and baking plate 2, thereby being close to the bottom surface of the frying and baking plate 2, and the first heating element 12 and the second heating element 14 are used for heating the frying and baking plate 2 at the same time, so that the heat of the front surface and the bottom surface of the frying and baking plate 2 is pulled close, and the frying and baking efficiency of the frying and baking plate 2 can be improved.

As shown in fig. 12, in some embodiments, the second heating member 14 includes a main heating section 141 parallel to the bottom surface of the frying plate 2 and auxiliary heating sections 142 connected to two ends of the main heating section 141, wherein the free ends of the two auxiliary heating sections 142 are respectively rotatably disposed on the side wall of the inner cavity 11; when the second heating member 14 is at the second position, the main heating section 141 thereof is positioned below the frying plate 2, so that the bottom surface of the frying plate 2 is heated by the main heating section 141.

Preferably, the free end of the auxiliary heating section 142 of the present embodiment is rotatably disposed at the top of the side wall of the inner cavity 11, when the second heating member 14 is in the first position, the main heating section 141 thereof is located at the bottom of the cavity near the inner cavity 11, and when the second heating member 14 is switched from the first position to the second position, the second heating member 14 can be rotated upwards so that the upper part thereof is near the bottom of the frying and roasting plate 2.

When the second heating member 14 is in the second position, only the main heating section 141 may be located near the bottom surface of the frying plate 2, or all of the main heating section 141 and part of the auxiliary heating section 142 may be located near the bottom surface of the frying plate 2.

Of course, when the frying plate 2 is placed in the inner cavity, the linkage mechanism 5 can be not triggered, and the food on the frying plate 2 can be heated through the first heating element 12 and the third heating element 13.

Preferably, the free ends of the two auxiliary heating sections 142 of the present embodiment correspond to one set of the linkage mechanisms 5, so that the stability of the rotation of the second heating member 14 can be ensured by the two sets of linkage mechanisms 5.

As shown in fig. 12, in some embodiments, the secondary heating section 142 includes a first heating section 1421 and a second heating section 1422 that are connected. One end of the first heating section 1421 is connected to one end of the second heating section 1422, the other end of the first heating section 1421 is connected to the main heating section 141, and the free end of the second heating section 1422 forms a free end of the auxiliary heating section 142.

Further, the second heating element 14 may be formed by bending a heatable pipe body. The included angle between the first heating section 1421 and the second heating section 1422 is an acute angle, and the included angle between the first heating section 1421 and the main heating section 141 is an acute angle. This increases the overall length of the second heating member 14 within the inner cavity 11, thereby increasing the heating area of the second heating member 14.

The shape of the main heating section 141 and the shape of the auxiliary heating section 142 of the present embodiment are not particularly limited. For example, as shown in fig. 12, the main heating section 141 may be linear, or the main heating section 141 may be curved, so that the heating area of the main heating section 141 may be increased.

As shown in fig. 2, 3, 6 and 7, in some embodiments, the linkage 5 includes two parts, a rotating arm 53 and a linkage arm 54. The rotating arm 53 is fixedly connected with the auxiliary heating section 142, or the rotating arm 53 and the auxiliary heating section 142 are of an integrated structure, and the rotating arm 53 can drive the second heating element 14 to synchronously rotate.

The link arm 54 is provided on the inner chamber 11 and is movable relative to the inner chamber 11. The frying and roasting plate 2 can push the linkage arm 54 to move, and further, a first acting force for rotating the second heating element 14 from the first position to the second position is applied to the rotating arm 53 through the linkage arm 54.

Specifically, when the frying and roasting plate 2 is placed in the inner cavity 11, the linkage mechanism 5 is simple in structure and convenient to realize by moving the frying and roasting plate 2 to push the linkage arm 54 to move so as to rotate the second heating element 14.

As shown in fig. 2, 3, 6 and 7, in some embodiments, the linkage 5 further includes a resilient member disposed on the inner cavity 11, the resilient member being operable to couple with the rotating arm 53 and apply a second force to the rotating arm 53 that rotates the second heating member 14 from the second position to the first position. When the linkage arm 54 is no longer triggered by the frying plate 2, the second heating element 14 can automatically rotate to the first position under the second acting force exerted by the elastic element, so that the normal use of the chicken fork 3 or the frying basket 4 is prevented from being influenced.

As shown in fig. 2, 3, 6 and 7, in some embodiments, the linkage mechanism 5 further includes a torsion spring seat 50 fixed on the inner cavity 11, and the elastic member for connecting the rotating arm 53 may be a double-ended shackle torsion spring 51. The torsion spring seat 50 is provided with a support shaft 55 and an anchor portion 52.

The double-ended shackle torsion spring 51 of this embodiment is sleeved on the supporting shaft 55 of the torsion spring seat 50, the first end shackle of the double-ended shackle torsion spring 51 is hooked on the rotating shaft between the linkage arm 54 and the rotating arm 53, the second end shackle of the double-ended shackle torsion spring 51 is hooked on the anchoring portion 52 of the torsion spring seat 50, when the frying plate 2 pushes the linkage arm 54 to rotate the second heating member 14 from the first position to the second position, the double-ended shackle torsion spring 51 will be torsionally deformed, as shown in fig. 7, and once the frying plate 2 is taken out from the inner cavity 11, the double-ended shackle torsion spring 51 will resume to deform, and then the second heating member 14 is driven to rotate from the second position to the first position, as shown in fig. 3. The structure is simple in design, low in cost and convenient to realize.

Of course, the above-mentioned elastic member is merely exemplary, and in other embodiments, the elastic member may take other forms, such as a cylinder, etc.

As shown in fig. 4, the two side walls of the inner cavity 11 in the present embodiment are respectively provided with a plurality of layers of sliding grooves 18, the length direction of the sliding grooves 18 is parallel to the cavity bottom of the inner cavity 11, and each layer of sliding grooves 18 can be respectively used for placing food-holding devices. The frying and baking plate 2 is placed in one layer of the sliding grooves 18, and the chicken fork 3, the frying basket 4 and the like can be respectively placed in the sliding grooves 18 of other layers.

Preferably, the frying plate 2 is placed in the chute 18 at the upper level, so that it is ensured that part of the second heating element 14 can be rotated under the frying plate 2.

In this embodiment, as shown in fig. 1, the frying plate 2, the chicken fork 3 and the frying basket 4 may be placed on the inner cavity 11 in this order from top to bottom. And the frying plate 2, the chicken fork 3 and the frying basket 4 can be simultaneously placed in the inner cavity 11, so long as the frying plate 2 is ensured not to trigger the linkage mechanism 5.

Further, in some embodiments, the frying plate 2 has a first stroke and a second stroke in the sliding groove 18 of the inner cavity 11 along the moving direction thereof. The frying plate 2 can move back and forth in a first stroke and a second stroke.

The length of the first stroke is greater than the length of the frying plate 2 along the extending direction of the chute 18, or, it is understood that the length of the first stroke is greater than the width of the frying plate 2, and the linkage mechanism 5 may not be triggered when the frying plate 2 is in the first stroke; when the baking plate 2 moves from the first stroke to the second stroke, the baking plate 2 may trigger the linkage 5. Thus, if it is desired to use the frying pan 2, the chicken fork 3 and the frying basket 4 together, the frying pan 2 can be placed in the first stroke in which the linkage 5 is not activated, so that the second heating element 14 will not rotate. Accordingly, the grill and/or basket 4 can be continuously placed inward, so that food can be simultaneously cooked by the grill plate 2, the grill fork 3, and/or the basket 4, thereby improving work efficiency.

In addition, the frying plate 2 and/or the frying basket 4 can be placed in the inner cavity 11 instead of being placed in the inner cavity 11, and the linkage mechanism 5 of the embodiment is not triggered, and the second heating element 14 is positioned at the first position, so that the food is heated simultaneously through the first heating element 12 at the top of the cavity, the second heating element 14 at the rear wall and the third heating element 13 at the bottom of the cavity, and the heating efficiency of the oven is improved.
