The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

An oven 1 implemented according to the present invention is described below with reference to the accompanying drawings.

As shown in fig. 2 to 12, the oven 1 according to the embodiment of the present invention includes a cavity 100, a driving device 200, a grill 300, and a grill shaft 400.

The cavity 100 defines a cooking chamber 110 therein, and the cavity 100 may be made of corrosion-resistant and environmentally friendly materials (e.g., Q195, Q235, SUS430, SUS304, etc.). Grill assembly 300 is movably disposed within cavity 100 between a first position and a second position. The roasting shaft 400 is rotatably disposed on the roasting assembly 300, the food material can be fixed on the roasting shaft 400, and can be turned over to roast the food material along with the rotation of the roasting shaft 400, and optionally, in order to facilitate the fixation of the food material, the roasting shaft 400 can be further provided with a roasting fork 420 rotating along with the roasting shaft 400.

When the barbecue grill 300 is located at the first position (as shown in fig. 2-4), the barbecue grill 300 is accommodated in the cooking chamber 110, so that the door (not shown) closes the cooking chamber 110, and the barbecue grill 300 is combined with the driving device 200, and the driving device 200 drives the barbecue shaft 400 to rotate through the barbecue grill 300. When the grilling component 300 is in the second position (shown in fig. 5 and 6), the grilling component 300 extends out of the cooking chamber 110, for example, the grilling component 300 with the grilling shaft 400 extends out of the cooking chamber 110, so that the user can conveniently pick and place the food material.

According to the oven 1 of the embodiment of the invention, the barbecue set frame 300 which is movable between the first position and the second position can be arranged, and the barbecue set frame 300 can be used for driving the barbecue shaft 400 to move, so that the oven accords with human engineering, and a user can take and place food materials by moving the barbecue set frame 300, so that the use is more convenient.

Therefore, the oven 1 according to the embodiment of the invention has the function of turning over and roasting, and is good in cooking performance and convenient to use.

In some embodiments of the present invention, the front surface of the cooking chamber 110 is open, the grilling component 300 is movable back and forth between the first position and the second position, the grilling component 300 is moved from the first position to the second position by the forward movement, and the grilling component 300 is moved from the second position to the first position by the backward movement. The rotation axis of the roast shaft 400 extends in the left-right direction, i.e., in the horizontal direction, instead of the diagonal design, eliminating interference with the hot wind motor cover 600.

When the barbecue set frame 300 is located at the second position, the barbecue set frame 300 can be separated from the driving device 200, so that the structure is further optimized, and when a user needs to operate food materials and move the barbecue set frame 300 to the second position, the transmission of power can be automatically cut off, and the barbecue set frame is safer and more reliable. Of course, the on/off of the driving device 200 may be controlled according to actual requirements.
