Description

Technical Field

[0001] The utility model relates to the technical field of household kitchen appliances, and more specifically, to a turntable electric oven. Background Art

[0002] In order to ensure that the food is cooked evenly in the electric ovens and grills currently on the domestic and foreign markets, the location, number and power distribution of the heating tubes must be repeatedly simulated and verified during the design and prototype stages. Even so, many electric ovens and grills still have uneven food cooking, especially for machines with irregular or flat cavities. In order to improve this disadvantage, some products have designed a side-rotating food cage or food fork structure, but this structure requires a large height space, and sometimes the food does not rotate with the food or damages the motor shaft due to slippage.

[0003] An electric oven is currently available, comprising a body, wherein a motor and a heating chamber are arranged in the body, wherein the motor comprises a motor shaft joint, wherein the motor shaft joint is arranged on a side wall of the heating chamber, and the motor shaft joint is used to be detachably connected to a rotating baking device; the rotating baking device comprises a turntable device, wherein the turntable device comprises a bracket, a turntable and a transmission device; the turntable device is detachably supported on the inner wall of the heating chamber by the bracket, and at this time, the transmission device of the turntable device is engaged with the motor shaft joint so that the motor can drive the transmission device to rotate, and the turntable is mounted on the bracket and driven by the transmission device to rotate horizontally in the heating chamber.

[0004] Although the above-mentioned existing electric oven can rotate the turntable to make the food heated more evenly, its motor will be roasted by the high temperature in the oven, which may easily cause damage to the motor. Utility Model Content

[0005] The utility model provides a rotary table electric oven to overcome the problem that the motor of the rotating baking tray described in the prior art is easily damaged by high temperature.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is: a turntable electric oven, including a box body, a heating element is provided in the box body, a rotating rack for mounting a baking tray is provided at the inner bottom of the box body, and a heat insulation cover is provided at the bottom of the rotating rack; a driving assembly is also provided at the bottom of the box body, and the heat insulation cover is provided on the top of the driving assembly; the driving assembly is dynamically connected to the heat insulation cover.

[0007] The box body is used to hold food; the rotating rack is used to support food-holding utensils such as baking trays or pizza trays; the heating element is used to generate heat to bake food; the driving component drives the heat insulation cover to rotate, and the rotating rack is on the heat insulation cover, thereby driving the rotating rack and the baking tray to rotate, so that the food on the baking tray rotates together, so that the food can be heated evenly; the heat insulation cover is arranged on the top of the driving component, so as to separate the driving component from the high temperature environment in the box body, thereby preventing the driving component from being damaged by high temperature.

[0008] Furthermore, the rotating frame includes a mounting portion and a plurality of supporting portions; the supporting portion is arranged on the heat insulation cover; the plurality of mounting portions are arranged on the supporting portion, and the mounting portion has a through opening.

[0009] By adopting the above technical solution, a through hole is provided on the mounting part, so that the heat from the bottom of the mounting part can pass through the through hole and be transferred to the baking pan on the mounting part, thereby avoiding the bottom of the baking pan being difficult to heat due to the obstruction of the mounting part.
