A heating element 201 is installed on the rotating control box 2 and extends into the first cavity 101. An oil cylinder 3 is placed on the first cavity 101, and oil is placed in the oil cylinder 3. The heating element 201 heats the oil. When oil needs to be replaced, the rotating control box 2 can be flipped on the fryer body 1, allowing the heating element 201 to leave the first cavity 101. Then, the oil cylinder 3 can be lifted for replacement. Support hinge seats 11 are located on both sides of the fryer body 1. The rotating control box 2 is located between the support hinge seats 11. A hinge mechanism is provided between the support hinge seats 11 and the rotating control box 2. The hinge mechanism includes an outer ring 21 and an inner wheel 12. The inner side of the outer ring 21... The inner ring 211 is provided with internal teeth 211, which cover the inner side of the outer ring 21. The inner wheel 12 is located inside the outer ring 21, and the outer side of the inner wheel 12 is provided with protruding teeth 121. The lower side of the protruding teeth 121 is provided with a slot 122. The function of the slot 122 is to make the protruding teeth 121 elastic. The protruding teeth 121 are engaged with the internal teeth 211. The slot 122 makes the protruding teeth 121 elastic. In this way, when the rotary control box 2 is rotated, the protruding teeth 121 are engaged with the internal teeth 121. When the rotary control box 2 is pushed, the protruding teeth 121 are pressed down by the pressure of the internal teeth 121. The slot 122 provides a receiving position. When the next internal tooth 211 is reached, it will spring up and engage. In this way, it can achieve a fixed position at any angle. This method only requires one hand to rotate and fix the rotary control box 2. It is simple to operate, has high working efficiency, strong sturdiness, and is not easy to slip.

[0022] As an optional embodiment, the inner wheel 12 has at least two teeth 121, or three teeth, preferably three, and the length and position of the slot 122 need to be reserved.

[0023] As an optional embodiment, the outer ring 21 is disposed on the side of the rotary control box 2, and the inner wheel 12 is mounted on the side of the support hinge 11.

[0024] As an optional embodiment, the distance from the convex tooth 121 to the axis of the inner wheel 12 forms a length A, and the radius of the inner wheel 12 forms a length B. The length of distance A is greater than the length of distance B. The edge of the radius of the inner wheel 12 fits against the convex tooth 121 of the outer ring, so that there will be no shaking. The convex tooth 121 is higher than the radius of the inner wheel 12, so it is easier to engage between the convex teeth 121, and the stability is stronger.

[0025] As an optional embodiment, when the inner wheel 12 is mounted on the outer ring 21, a limiting cover 124 is installed on the inner wheel 12.

The outer edge of the limiting cover 124 is larger than the diameter of the outer ring 21, which can play a fixing role and make it easier for the inner wheel 12 to rotate.

[0026] As an optional embodiment, a positioning post 111 and a positioning hole 123 are provided between the inner wheel 12 and the support hinge 11. The positioning post 111 is inserted into the positioning hole 123 to fix it and facilitates installation.

[0027] As an optional embodiment, a protective switch contact 13 is installed on the inner wheel 12, and a micro switch 22 is provided inside the rotary control box 2. When the rotary control box 2 is in operation, the micro switch 22 contacts the protective switch contact 13 to energize it. After the rotary control box 2 is rotated open, the micro switch 22 separates from the protective switch contact 13 to de-energize it, preventing the heating element 201 from continuing to heat up after the rotary control box 2 is opened. To improve safety, the circuit is disconnected when the micro switch 22 separates from the protective switch contact 13.

[0028] As an optional embodiment, a handle 23 is fixed on the rotary control box 2, and the handle 23 is for convenient flipping of the rotary control box 2.

[0029] As an optional embodiment, a control module 4 is provided on the front side of the fryer body 1. The control module 4 can be used to output operation instructions, which may be a time button or a heating temperature control button.

[0030] In existing technologies such as Figure 1 The rotating control box shown requires one hand to rotate it and the other hand to tighten the screw. This method is cumbersome and inefficient. If the screw is not tightened properly, the heating element may fall onto the oil cylinder, posing a safety hazard. Therefore, a rotating control box for the heating element of an fryer is provided. A hinge mechanism is provided between the supporting hinge seat 11 and the rotating control box 2.
