The fixing member 51 can be vertically connected to the second connecting rod 42 and remain horizontal during the movement. The pull-out grill 30 can move forward and backward under the support of the two load-bearing pulleys 52, thereby realizing the pulling action of entering or leaving the baking chamber 11. Preferably, at least two guide wheels 53 are further provided on one side of the fixing member 51 close to the pull-out grill 30, the rotation axis of the guide wheel 53 is perpendicular to the rotation axis of the load-bearing pulley 52, and the circumferential surface of the guide wheel 53 is used to abut the side of the pull-out grill 30. When the pull-out grill 30 moves forward and backward, the left and right sides abut against the circumferential surface of the guide wheel 53, which can reduce the shaking in the left and right directions. The pull-out grill 30 can be provided with a limit pin 35 to prevent the pull-out grill 30 from slipping off the pulley assembly 50. When the pull-out grill 30 is pulled out, the limit pin 35 is blocked by the guide wheel 53.

[0043] In this embodiment, the pull-out grill 30 is in the shape of a drawer, and the pull-out grill 30 is detachably connected to the lifting assembly 40. Therefore, the user can easily clean the pull-out grill 30; after the food on the pull-out grill 30 is baked, the pull-out grill 30 is pulled out and replaced with a spare pull-out grill 30 to continue baking food, which can improve the working efficiency of the oven 100. When the pull-out grill 30 is pulled out, the guide wheel 53 blocks the limit pin 35, so that the pull-out grill 30 will not slip off the pulley assembly 50.

[0044] The height of the pull-out grill 30 can be set to a plurality of levels, and the height of the pull-out grill 30 can be adjusted and locked by a locking assembly 60 .

[0045] Figure 8 is a schematic structural diagram of the adjustment rod 62 involved in the present invention; Fig. 9 It is a schematic structural diagram of the locking assembly 60 involved in the present invention.

[0046] The locking assembly 60 includes a slot seat 61, an elastic component, an adjustment rod 62 and a clamping rod 63. The slot seat 61 is fixedly mounted on the oven body 10. The slot seat 61 is provided with a plurality of clamping slots 611 arranged in the height direction. The notches of the clamping slots 611 face the inside of the baking chamber 11. The elastic component is mounted on the second connecting rod 42 and connected to the adjustment rod 62. The elastic component is used to generate an elastic force to push the adjustment rod 62 to the outside of the baking chamber 11. The clamping rod 63 is vertically connected to the adjustment rod 62. The clamping rod 63 is used to be inserted into the clamping slot 611 to limit the height of the fixing member. The elastic component may include a spring 65 and a spring seat 66. The spring seat 66 is mounted on the fixing member. The two ends of the spring 65 are respectively in contact with the spring seat 66 and the adjustment rod 62, so as to generate an elastic force to push the adjustment rod 62 to the outside of the baking chamber 11. The outward end of the adjustment rod 62 may be provided with a handle 64 for easy gripping. When adjusting the height of the pull-out grill 30, the adjusting rod 62 is pushed toward the inside of the baking chamber 11 to overcome the force of the spring 65, so that the locking rod 63 can be disengaged from the locking groove 611. After determining the height of the pull-out grill 30, the adjusting rod 62 is released, and the spring 65 pushes the adjusting rod 62 out of the baking chamber 11, so that the locking rod 63 can enter the locking groove 611, thereby locking the height of the pull-out grill 30.

[0047] The oil drain assembly includes an upper oil drop plate 71, a lower oil drop plate 72 and an oil container 73. The upper oil drop plate 71 and the lower oil drop plate 72 are arranged below the pull-out grill 30.

The grill plate 81 is arranged above the heater 20. The temperature of the grill plate 81 is higher. Various foods can be fried on the grill plate 81, so that the heat generated by the barbecue can be more efficiently utilized. The oil on the grill plate 81 can flow to the oil guide groove 82 on the oil guide plate, and then flow from the oil outlet to the oil pan 83, so that the impact of oil pollution on the environment can be reduced. In some cases, the oil flowing down from the grill plate 81 can also be recycled, which can reduce the cost of the catering operator. The smoke exhaust port 12 can be arranged at the rear of the grill plate 81.

[0049] In the present embodiment, the use process of the oven 100 is as follows: pull the handle on the heat-insulating baffle plate 32 to pull the pull-out grill 30 so that it slides under the support of the load-bearing pulley 52 until it is pulled out to the limit pin 35 and is blocked by the guide wheel 53, place the food to be grilled on the pull-out grill 30, slide the pull-out grill 30 back into the oven body 10, push the clamping rod 63 out of the clamping groove 611, and the pull-out grill 30 rises to a position close to the heater 20 as the counterweight block 44 descends by itself, and then push the clamping rod 63 into the clamping groove 611 at other corresponding positions, thereby fixing the position of the pull-out grill 30; turn on the gas switch to make the heater 20 work normally, and the heater 20 heats the grilled food from the top to prevent the oil generated by the grilled food from directly contacting the gas and producing During the grilling process, the oil on the pull-out grill 30 flows from the upper oil drop plate 71 to the lower oil drop plate 72, and flows from high to low into the oil container 73 hung on the outside of the furnace body 10 through the lower oil drop plate 72; during use, the arc or inclined fire baffle 33 can protect the safety of the user and prevent the high temperature flame of the heater 20 from burning people; during the grilling process, the user fries various foods on the grill plate 81 at the same time, and the oil on the grill plate 81 flows into the oil guide groove with the oil outlet, and flows into the oil basin 83 through the oil outlet; if the distance between the pull-out grill 30 and the heater 20 needs to be adjusted during use of the oven 100, it is only necessary to push the clamping rod 63 out of the clamping groove 611 to adjust the height, and then push the clamping rod 63 into the corresponding clamping groove 611. The oil smoke during use is discharged through the exhaust port 12 set at the rear of the grill plate 81. The oven 100 needs to be cleaned after use.
