[0002] An automatic cooking machine is an intelligently programmable automated cooking device and a new generation of microcomputer-controlled intelligent cooking equipment. The heating mechanism of a traditional cooking machine usually uses resistance wire or quartz tube as a heating element. Heat is generated by passing current through these elements, and then the heat is transferred to the heated object by convection or radiation. This traditional heating method has some problems, such as low heating efficiency, high energy consumption, and short service life. Therefore, a new type of electromagnetic heating mechanism for cooking machines has appeared on the market. It uses electromagnetic heating and does not need to generate heat through resistance wire or quartz tube. Therefore, there is no resistance heat loss and the energy conversion efficiency is high. The working state of the coil is controlled by a controller to maintain a constant heating temperature, avoiding the energy waste caused by unstable temperature in traditional heating methods. This electromagnetic heating mechanism is mainly composed of an outer shell, a coil, a cooling fan, and a controller.

[0003] When the electromagnetic heating mechanism of a cooking machine in the prior art is actually used, the cooling fan is generally fixed directly on the inner bottom end of the outer shell by multiple screws.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example 1

[0022] See also Figures 1 to 8, which is the first embodiment of the utility model, and this embodiment provides a technical solution: an electromagnetic heating mechanism for a cooking machine, comprising an outer shell 1, an electromagnetic coil 2 and a cooling fan 3, both of which are installed on the inner side of the outer shell 1, when powered on, an alternating magnetic field is generated in the electromagnetic coil 2, and when an iron-containing object approaches, eddy currents are generated inside the object, thereby generating heat, the cooling fan 3 is located at the bottom end of the outer shell 1, and a plurality of air holes 11 corresponding to the cooling fan 3 are provided on the bottom surface of the outer shell 1, and a disassembly structure 4 is provided between the cooling fan 3 and the outer shell 1;

[0023] The disassembly and assembly structure 4 includes a rotating base strip 41, a connecting shaft block 42, a rotating plug rod 43 and a limiting side block 44. A rotating plug rod 43 is rotatably installed at the four corners of the cooling fan 3. The bottom end of the rotating plug rod 43 extends to the bottom of the cooling fan 3, and the limiting side block 44 is welded and fixed to the bottom end surface of the rotating plug rod 43. The top end of the rotating plug rod 43 is welded and fixed with a connecting shaft block 42. The top end of the connecting shaft block 42 penetrates to the top of the cooling fan 3. The top end of the connecting shaft block 42 is fixed with a rotating base strip 41 relative to the top surface of the cooling fan 3. The bottom end surface of the outer shell 1 is provided with four sockets 45 corresponding to the rotating plug rod 43, and one side of each socket 45 is provided with a side groove 46 corresponding to the limiting side block 44, so that the operator can complete the disassembly and assembly of the cooling fan 3 by hand.

[0024] Among them, a limiting structure 5 is also arranged at the four corners of the cooling fan 3, and the limiting structure 5 includes a pull bar 51, a side slider 52, a side slide groove 53, a limiting push rod 54 and a limiting slot 55. The side slide groove 53 is arranged on the outer surface of the cooling fan 3, and the side slider 52 is slidably arranged in the side slide groove 53. The limiting push rod 54 is fixedly welded on the top of the side slider 52. Two limiting slots 55 corresponding to the limiting push rod 54 are symmetrically arranged on the bottom surface of the rotating base bar 41. The top end of the limiting push rod 54 penetrates into one of the limiting slots 55, which can play a stable limiting effect on the rotating base bar 41. To ensure the position stability of the rotating plug rod 43 and the limiting side block 44 during daily use, one end of the side slide block 52 extends to the surface of the cooling fan 3 and is fixedly connected to a pull bar 51. A vertical rod 56 is also fixed in the side slide groove 53. The side slide block 52 is movably sleeved on the vertical rod 56. A spring 57 is also sleeved and installed on the surface of the vertical rod 56. The spring 57 is at the bottom of the side slide block 52. If the cooling fan 3 is to be disassembled and assembled later, the pull bar 51 is first pulled down so that the side slide block 52 compresses the spring 57 and moves the top end of the limiting top rod 54 out of the limiting slot 55, so that the limiting of the rotating base bar 41 can be released. The operator can then rotate the rotating base strip 41 so that the connecting shaft block 42 rotates with the rotating plug rod 43. After the rotating base strip 41 rotates 180 degrees, the limiting side block 44 will also rotate to the bottom of the side groove 46. The operator can then move the cooling fan 3 upwards, so that the limiting side block 44 can move upwards to the inner side of the outer shell 1 through the side groove 46, thereby realizing the rapid separation of the cooling fan 3 from the outer shell 1, greatly improving the convenience of disassembly and assembly between the cooling fan 3 and the outer shell 1. The same is true for the subsequent installation of the cooling fan 3. First, press the cooling fan 3 at the inner bottom end of the outer shell 1 to make the cooling fan 3 The bottom end of the rotating rod 43 is penetrated to the outside of the bottom of the outer shell 1, and the limiting side block 44 is also penetrated to the outside of the bottom of the outer shell 1 through the side groove 46. At this time, the pull bar 51 is pulled down again, and then the rotating base bar 41 is rotated 180 degrees, so that the limiting side block 44 is no longer aligned with the side groove 46, and then the pull bar 51 is released, so that the spring 57 pushes the side slider 52 back to reset, and the top end of the limiting top rod 54 is stuck in the limiting slot 55, so that the rotating base bar 41 can be limited again, and the rotating rod 43 and the limiting side block 44 are effectively limited, thereby completing the rapid installation of the cooling fan 3.

[0025] Example 2

[0026] See also Figures 1 to 9 , which is the second embodiment of the utility model, is based on the previous embodiment, and the difference is that the auxiliary positioning structure can be provided to play an auxiliary positioning effect in the initial installation of the cooling fan 3.

[0027] Specifically, an auxiliary positioning structure is also provided between the cooling fan 3 and the outer shell 1, and the auxiliary positioning structure includes an L-shaped rubber pad 12, a strip protrusion 13 and a strip card slot 31. The L-shaped rubber pad 12 is fixed to the inner bottom end of the outer shell 1, and one side of the L-shaped rubber pad 12 is provided with an integrated strip protrusion 13, both of which are made of fluororubber material. The surfaces of both sides of the cooling fan 3 are provided with strip card slots 31 corresponding to the strip protrusion 13, and the strip protrusion 13 is embedded in the strip card slot 31. When the cooling fan 3 is installed At the initial stage of installation, the operator will press the cooling fan 3 to the inner bottom end of the outer shell 1, and make the bottom end of the rotating rod 43 and the limiting side block 44 penetrate to the outer bottom end of the outer shell 1. At this time, the cooling fan 3 will be between the two L-shaped rubber pads 12, and the strip protrusion 13 will be squeezed into the strip card groove 31, so that the strip protrusions 13 on both sides will have a certain auxiliary limiting effect on the cooling fan 3, preventing the cooling fan 3 from moving up, and facilitating the operator to perform subsequent operations such as rotation limiting of the rotating base strip 41.
