Description

TECHNICAL FIELD

[0001] The utility model relates to the field of cooking equipment, in particular to an improved structure of electric oven base. BACKGROUND

[0002] At present, the common electric oven usually includes a base, a baking tray and a stove head. The baking tray is installed on the base for carrying food, the base is connected with a support arm on one side, and the stove head is rotatably arranged above the baking tray through the support arm, so as to bake the food on the baking tray. The user can conveniently take the food on the baking tray by rotating the stove head to one side. In order to avoid the support arm from interfering with the user's cooking operation on the baking tray, the size of the base is usually designed to be larger, and the size of the support arm is designed to be smaller, so that a necked structure is formed at the connection between the base and the support arm. However, the stove head is heavy, and during the long-term use of the electric oven, especially when the stove head is rotated to one side, the necked structure is subjected to a large stress due to stress concentration, and is prone to deformation or even damage, which not only affects the overall stability and service life of the electric oven, but also may cause safety hazards and reduce the user's experience. Therefore, it is urgent to improve the connection structure of the electric oven base and the support arm to solve the above technical problems. SUMMARY

[0003] The utility model aims at solving the above technical problems, and provides an improved structure of electric oven base. The application improves the base structure so that it is not easy to deform.

[0004] An improved structure of electric oven base includes a base, a support arm, a reinforcing plate, a center pipe and a stove head. The base includes a mounting body and a necked portion extending from the mounting body to one side. The support arm is installed on the necked portion. The reinforcing plate is in the shape of a long strip. The middle part of the reinforcing plate is fixed to the bottom surface of the necked portion. One side of the reinforcing plate is fixed to the bottom surface of the base, and the other side extends below the support arm and is fixedly connected with the center pipe. The center pipe passes through the support arm upward and extends into the stove head, so that the stove head is rotatably arranged above the base.

[0005] According to the improved structure of electric oven base of the application, the center pipe, the necked portion and the mounting body are connected by the reinforcing plate. The force generated by the stove head is transmitted to the reinforcing plate through the center pipe, so that the stress originally borne by the necked portion is shared by the necked portion and the mounting body, and the stress borne by the necked portion is reduced, thereby preventing the necked portion from deforming. In addition, the reinforcing plate reinforces the structure of the necked portion by using its own structural strength, so that the necked portion is less likely to deform.

[0006] Further, the necking part is an axisymmetric structure, and the reinforcing plate is arranged on the axis of symmetry of the necking part. Arranged on the axis of symmetry, the stress can be more evenly distributed to the two sides of the necking part.

[0007] Still further, the lower end of the central pipe is provided with a fixing screw, the fixing screw passes through the reinforcing plate, and the reinforcing plate is clamped at the lower end of the central pipe through a nut.

[0008] Still further, the reinforcing plate oppositely extends an extension plate relative to the central pipe, and the extension plate extends along the length direction of the reinforcing plate. The extension plate can reinforce the structural strength of the reinforcing plate, so that the reinforcing plate is not easily deformed by stress, thereby making the necking part more difficult to deform.

[0009] Still further, the bottom cover is arranged on the bottom surface of the base, and is formed with a mounting cavity for mounting the circuit board, and the reinforcing plate is arranged above the circuit board in the mounting cavity. Since the reinforcing plate reinforces the structure of the necking part, the circuit board arranged there is not easily deformed, so that the circuit board can stably operate.

[0010] Still further, the central pipe is a hollow wiring pipe, the reinforcing plate is provided with a wiring hole, the furnace head is provided with a heating device, and the circuit board is electrically connected with the heating device through the wiring hole and the central pipe.

[0011] Still further, the reinforcing plate is a metal reinforcing plate. BRIEF DESCRIPTION OF DRAWINGS
