Example one

Referring to fig. 1 to 3, an oven 100 according to the present invention includes a housing 10, a heating element 20, and a grill 30 for holding food. The heating assembly 20 is used for providing heat for food materials, and includes a first heating pipe 21 and a second heating pipe 22 which are arranged in the box body 10 at an interval from top to bottom. A cooking chamber 101 for cooking food is formed between the first and second

heat generating pipes

21 and 22. The cabinet 10 is provided with a variable volume driving device 40 capable of driving at least the first heat-generating pipe 21 to move to adjust the size of the cooking cavity 101, and when the oven 100 is set to be in the barbecue mode, the variable volume driving device 40 drives the first heat-generating pipe 21 to approach the barbecue grill 30 to a set position to reduce the cooking cavity 101.

Further, the grill 30 is disposed between the first heat generation pipe 21 and the second heat generation pipe 22, and the second heat generation pipe 22 is disposed to be close to the grill 30 by being driven by the volume-varying driving device 40, so that the cooking chamber 101 is made small. Further preferably, the first heat generating tube 21 and the second heat generating tube 22 are driven by the volume-variable driving device 40 in synchronization. The first heating tube 21 and the second heating tube 22 are mirror-symmetrical, and when the first heating tube 21 and the second heating tube 22 rotate synchronously, the first heating tube 21 and the second heating tube 22 approach to or move away from the grill 30 synchronously.

In the present embodiment, the barbecue mode is such that the oven generates a local high temperature near the barbecue grill 30, and the food material on the barbecue grill 30 is heated at a position close to the heat source (the first heat-generating pipe 21 and/or the second heat-generating pipe 22), so that a strong flavor and a delicious taste are generated, thereby achieving a barbecue effect. The food material can be made into kebabs for roasting, or can be placed on a latticed roasting net for roasting. When the oven 100 is set to be in the non-barbecue mode, the variable volume driving device 40 drives the first heat generating pipe 21 and/or the second heat generating pipe 22 to move away from the set position and away from the barbecue grill 30, and the first heat generating pipe 21 and the second heat generating pipe 22 form a uniform heating effect on the space in the oven.

heat generating pipes

21 and 22 becomes shorter, and the formed cooking chamber 101 becomes smaller. When the first and second

heat generation pipes

21 and 22 are moved to a position relatively far away from the grill 30, the distance between the first and second

heat generation pipes

21 and 22 is large, and the formed cooking chamber 101 becomes large.

Further, the first heat-generating pipe 21 includes a shaft portion 211 having a first axis C and a heat-generating portion 212 connected to the shaft portion 211, and the shaft portion 211 is driven to rotate by the volume-varying driving device 40 such that the heat-generating portion 212 rotates about the first axis C to adjust the size of the cooking cavity 101. Further, the heat generating portion 212 is configured to protrude to one side of the shaft portion 211.
