Description

Technical Field

[0001] This utility model relates to the field of induction cooker technology, and in particular to an explosion-proof and flame-retardant induction cooker. Background Technology

[0002] Commercial induction cookers refer to induction cookers used in commercial kitchens. They are mainly used in commercial kitchens such as restaurants, hotels, factories, schools, government agencies, military units, enterprises, trains, and ships. They are particularly suitable for environments where the use of open flames is restricted, such as basements, underground shopping malls, railway vehicles, gas stations, and aviation.

[0003] In the prior art, such as in publication number CN206846819U, a ventilation and heat dissipation device for a commercial induction cooker and a commercial induction cooker are disclosed. It includes a first suction fan and a second suction fan; it also includes an oil fume filtration mechanism, which includes a first frame and a second frame; a first baffle and a second baffle are disposed between the first frame and the second frame, and the first baffle and the second baffle are offset from each other; the first suction fan is connected to a first exhaust duct, and the first exhaust duct is connected to an exhaust port; the second exhaust fan is connected to a second exhaust duct.

[0004] While the aforementioned patents effectively dissipate heat from the induction cooker and prevent oil, sewage, bedbugs, and rodents from entering and damaging the system, ensuring its normal operation, this application also covers commercial induction cookers. However, as induction cookers are used over time, a certain amount of dust accumulates in the ventilation area at the bottom. The presence of dust affects the efficiency of heat dissipation and ventilation, and heat cannot be conducted through the gas, resulting in low efficiency. Therefore, to address the above problems, an explosion-proof and flame-retardant induction cooker is proposed. Utility Model Content

[0005] This utility model addresses the shortcomings of existing technologies by providing the following technical solution:

[0006] An explosion-proof and flame-retardant induction cooker includes a cabinet; an A stove and a B stove are respectively arranged on the left and right sides of the top surface of the cabinet; a square groove is opened on the back of the cabinet; a heating module for regulating the electromagnetic heating of the A stove and the B stove is arranged inside the square groove; and a drive component for reducing the internal temperature of the cabinet and cleaning the ventilation opening is arranged symmetrically on the surface of the heating module along a horizontal axis.

[0007] The drive assembly includes an A thermal pad arranged axially symmetrically on the surface of the heating module, an integrated heat sink plate disposed on the surface of the A thermal pad, a copper tube penetrating the interior of the integrated heat sink plate, a B thermal pad disposed at one end of the copper tube, a fixing plate disposed on the surface of the B thermal pad, and a cooling fan disposed on the surface of the fixing plate.

[0008] An L-shaped rocker arm is fixedly connected to the surface of the cooling fan. One end of the L-shaped rocker arm has a through hole. A connecting rod is slidably connected inside the through hole. A fixing rod is slidably connected inside one end of the connecting rod. Both ends of the fixing rod are fixedly connected to connecting plates. A crossbar is provided on one side of the surface of the connecting plate. A flexible brush is provided on the surface of the crossbar.

[0009] As an improvement to the above technical solution, a T-plate is movably connected to one side of the connecting piece, and one end of the T-plate is fixedly connected to both sides of the surface of the fixing plate.

[0010] As an improvement to the above technical solution, the surface of the fixing plate is provided with a number of airflow holes for heat transfer, and the airflow holes are distributed in a rectangular array.

[0011] As an improvement to the above technical solution, a protective cover is fitted onto the edge of the square groove and the surface of the drive component. The surface of the protective cover has a ventilation groove corresponding to the drive component, and a cross-shaped protective baffle is provided inside the ventilation groove. The surface of the cross-shaped protective baffle is in contact with and overlaps the flexible brush.

[0012] As an improvement to the above technical solution, a water storage tank is provided on the top of the cabinet and between stove A and stove B, and there are two water storage tanks.

[0013] As an improvement to the above technical solution, a baffle is provided at the edge of the top of the cabinet, and a faucet corresponding to the water storage tank is provided on the surface of the baffle.

[0014] The beneficial effects of this utility model are:

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the following provides a more detailed description of the utility model. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the utility model.

[0023] Please see Figures 1-4 As shown, an explosion-proof and flame-retardant induction cooker includes a cabinet 1; an A-burner 2 and a B-burner 3 are respectively arranged on the left and right sides of the top surface of the cabinet 1; a square groove is opened on the back of the cabinet 1, and a heating module 4 for regulating the electromagnetic heating of the A-burner 2 and the B-burner 3 is arranged inside the square groove; a drive component 5 for reducing the internal temperature of the cabinet 1 and cleaning the ventilation opening is arranged symmetrically on the surface of the heating module 4; the drive component 5 includes an A-heat-conducting pad 51 arranged symmetrically on the surface of the heating module 4; an integrated heat dissipation plate 52 is arranged on the surface of the A-heat-conducting pad 51; a copper tube 53 runs through the interior of the integrated heat dissipation plate 52; a B-heat-conducting pad 54 is arranged at one end of the copper tube 53; a fixing plate 55 is arranged on the surface of the B-heat-conducting pad 54; and a cooling fan 56 is arranged on the surface of the fixing plate 55.

[0024] During operation, thermal pads A 51 and B 54 conduct heat from the heat-generating module 4 to the integrated heat sink 52 and copper pipe 53. Combined with the forced airflow of the cooling fan 56, the heat dissipation efficiency is significantly improved. The integrated heat sink 52 and copper pipe 53 form a multi-level heat conduction path, which quickly disperses the heat from the heat-generating module 4. The rectangular array airflow holes 7 on the surface of the fixing plate 55 enhance airflow and, together with the cooling fan 56, form a directional airflow channel, which improves the heat dissipation efficiency.

[0025] Furthermore, an L-shaped rocker arm 561 is fixedly connected to the surface of the cooling fan 56. One end of the L-shaped rocker arm 561 has a through hole 562. A connecting rod 563 is slidably connected inside the through hole 562. A fixing rod 564 is slidably connected inside one end of the connecting rod 563. Both ends of the fixing rod 564 are fixedly connected to connecting pieces 565. A crossbar 566 is provided on one side of the surface of the connecting piece 565. A flexible brush 567 is provided on the surface of the crossbar 566.

[0026] When the cooling fan 56 is running, the L-shaped rocker arm 561 drives the connecting rod 563, the fixed rod 564 and the crossbar 566 to move together, so that the flexible brush 567 swings back and forth along the ventilation groove 9, automatically removing the dust on the surface of the protective cover 8 and preventing dust accumulation from blocking the heat dissipation.

[0027] Furthermore, a T-plate 6 is movably connected to one side of the connecting piece 565, and one end of the T-plate 6 is fixedly connected to both sides of the surface of the fixing plate 55.

[0028] During operation, the T-plate 6 provides stable support for the swing of the flexible brush 567, preventing the connecting piece 565 from shifting or jamming during movement, enhancing the stability of the cleaning action of the flexible brush 567, and extending the service life of the linkage mechanism.

[0029] Furthermore, a number of airflow holes 7 for heat transfer are opened on the surface of the fixing plate 55, and the airflow holes 7 are distributed in a rectangular array.

[0030] During operation, the airflow holes 7 distributed in a rectangular array on the surface of the fixed plate 55 form an auxiliary airflow channel, which accelerates the diffusion of heat from the integrated heat sink 52 to the outside, optimizes the heat dissipation airflow, increases the airflow coverage of the cooling fan 56, and reduces the risk of local high temperature.

[0031] Furthermore, a protective cover 8 is fitted onto the edge of the square groove and the surface of the drive component 5. The surface of the protective cover 8 is provided with a ventilation groove 9 corresponding to the drive component 5, and a cross-shaped protective baffle is provided inside the ventilation groove 9. The surface of the cross-shaped protective baffle is in contact with and overlaps with the flexible brush 567.

[0032] During operation, the protective cover 8 covers the drive assembly 5, and the cross-shaped baffle in its ventilation slot 9 prevents oil and foreign objects from entering the cabinet 1, while allowing airflow to pass through, thus balancing protection and ventilation needs, preventing external pollutants from damaging the heat dissipation system and reducing maintenance frequency.

[0033] Furthermore, a water storage tank 10 is provided on the top of the cabinet 1 and between stove A 2 and stove B 3. There are two water storage tanks 10. A baffle 11 is provided at the edge of the top of the cabinet 1. A faucet 12 corresponding to the water storage tank 10 is provided on the surface of the baffle 11.

[0034] During operation, in emergency situations such as localized overheating or fire, the baffle 11 isolates liquid splashes and quickly activates water storage for cooling, enhancing the equipment's explosion-proof and fire-resistant capabilities, while also providing a stable water supply during cooking.

[0035] Working principle: After stove A 2 and stove B 3 are powered on, heating module 4 generates electromagnetic eddy currents with a frequency of 20-40kHz, driving the bottom of the cookware to heat up to the set temperature. The heat generated by heating module 4 is transmitted through heating pad A 51 BergquistTflex. TM The HD300 absorbs and transfers heat to the finned structure of the integrated heat sink 52, and then conducts it through the copper pipe 53 to the thermal pad 54, realizing the directional transfer of heat from the heat source to the heat dissipation end, reducing the module temperature. When the cooling fan 56 runs, the airflow passes through the airflow holes 7 of the fixed plate 55, forming turbulence to enhance heat dissipation. When the cooling fan 56 runs, the L-shaped rocker arm 561 drives the connecting rod 563 and the fixed rod 564 to swing within the ventilation slot 9 of the flexible brush 567 on the crossbar 566, clearing the dust accumulated in the gap of the cross-shaped baffle. The hinge structure between the T-shaped plate 6 and the connecting piece 565 allows ±2° swing, offsetting the vibration of the cooling fan 56 and ensuring the deviation of the brush movement trajectory. During the swing, the hot air blown out by the cooling fan 56 also blows away the cleaned dust.

[0036] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
