[0033] As Figures 1 - 8 shown, a dry - burning - proof electromagnetic frying furnace according to an embodiment of the first aspect of the present utility model includes a base shell 100 and an electromagnetic module 200. The electromagnetic module 200 includes at least one electromagnetic driving part 210 and a supporting part 220. The electromagnetic driving part 210 is inclined. The electromagnetic driving part 210 and the supporting part 220 define at least part of a supporting surface for placing a pot body 300. The electromagnetic driving part 210 is used to cause the part of the pot body 300 facing the electromagnetic driving part 210 to couple and generate heat. Among them, the height of the supporting surface defined by the supporting part 220 is not higher than the height of the lowest point of the supporting surface defined by the electromagnetic driving part 210.

[0034] Among them, the base shell 100 can be a shell with a conventional structure. The pot body 300 can be placed inside the base shell 100. A top cover 400 can also be provided on the top of the pot body 300 in the base shell 100. The electromagnetic module 200 is arranged at the bottom of the base shell 100. The pot body 300 can be placed on the supporting surface of the electromagnetic module 200. The anti-dry-burning electromagnetic deep fryer further includes a control module 510, a driving module 520, and a power modulation module 530. As Figure 7 shown, the power modulation module 530 includes a rectifier bridge unit and a capacitor filtering unit, etc. The power modulation module 530 can be connected to an external AC power supply. The rectifier bridge unit rectifies the alternating current. After passing through the capacitor filtering unit, a suitable supply voltage is modulated to supply power to the electromagnetic module 200. As Figure 6 shown, the control module 510 includes a processing chip such as an MCU or a CPU and its affiliated circuits. As Figure 8 shown, the driving unit can include a plurality of semiconductor switching tubes. The electromagnetic driving part 210 can be formed by winding an electromagnetic coil 211. The pot body 300 can be close to the electromagnetic driving part 210. The driving unit is connected to both ends of the electromagnetic coil 211. The control module 510 controls the operation of the driving module 520, so as to apply an alternating current to both ends of the electromagnetic coil 211. The electromagnetic coil 211 is coupled with the pot body 300, making the pot body 300 heat up.

[0035] For the anti-dry-burning electromagnetic deep fryer of the present invention, the electromagnetic driving part 210 is inclined and defines at least part of the supporting surface with the supporting part 220. The pot body 300 is placed on the supporting surface. Part of the bottom surface of the pot body 300 is adapted to the electromagnetic driving part 210, and the other part of the bottom surface is adapted to the supporting part 220, so as to support the pot body 300. The electromagnetic driving part 210 mainly makes the position of the pot body 300 facing the electromagnetic driving part 210 heat up, rather than the part opposite to the electromagnetic driving part 210 being relatively far away from the electromagnetic driving part 210, and the heating temperature is lower. The fried food is in the pot body 300. Since the height of the supporting surface defined by the supporting part 220 is not higher than the lowest point of the supporting surface defined by the electromagnetic driving part 210, the fried food deposited at the bottom of the pot body 300 will be affected by gravity and tend to be located near the position facing the supporting part 220. The heating temperature here is lower, and it is not easy to fry the fried food until it turns black, and the pot body 300 is not easy to dry-burn due to this. This design improves the quality of the fried food and reduces the probability of the pot body 300 dry-burning.

[0036] In some embodiments of the present invention, as Figure 2 、 4 、5 shown, there are two electromagnetic driving parts 210, and the supporting part 220 is located between the two electromagnetic driving parts 210.

[0037] The electromagnetic driving part 210 can be in a plate shape and is formed by a plate part of the base shell 100. Ribs can be provided on the surface of the plate part, and the electromagnetic coil 211 is wound around the ribs to form the electromagnetic driving part 210. The electromagnetic driving part 210 inclines downward from the side facing away from the supporting part 220 to the side close to the supporting part 220. Specifically, the cross-section of the supporting surface formed by the two electromagnetic driving parts 210 and the supporting part 220 is V-shaped.

[0038] In some embodiments of the present utility model, such as Figure 3 , 4 , as shown in Fig. 5, at least a part of the bottom surface of the pot body 300 is formed by connecting an inclined surface 310 and a flat surface 320. The bottom surface is placed on the supporting surface. Among them, the height of the flat surface 320 is not higher than the height of the lowest point of the inclined surface 310, so that the electromagnetic driving part 210 faces the inclined surface 310 and the flat surface 320 is placed on the supporting part 220.

[0039] The bottom surface of the pot body 300 has an inclined surface 310 that cooperates with the inclined electromagnetic driving part 210 and a flat surface 320 that can be placed on the supporting part 220. When the fried food settles to the bottom surface of the pot body 300, if it is located on the inclined surface 310, under the action of gravity, the fried food will fall along the inclined surface 310 into the flat surface 320. The flat surface 320 is relatively far from the electromagnetic driving part 210, and the oil temperature at the position is relatively low, so it is not easy to fry the fried food until it turns black.

[0040] Specifically, there are two inclined surfaces 310, and they are located on the left and right sides of the flat surface 320, so as to be adapted to the V-shaped supporting surface.

[0041] In some embodiments of the present utility model, a cold oil groove 330 is provided on the flat surface 320. The cold oil groove 330 is formed by concave downward at the flat surface 320. The bottom surface of the cold oil groove 330 is lower than the lowest point of the electromagnetic driving part 210, so that the coupling effect of the electromagnetic driving part 210 on the bottom surface of the cold oil groove 330 is smaller, and the oil temperature at the cold oil groove 330 is lower.

[0042] In some embodiments of the present utility model, such as Figure 2 , 3 , as shown in the figure, the flat surface 320 is in a long strip shape, the cold oil groove 330 is arranged along the length direction of the flat surface 320, the bottom surface of the cold oil groove 330 inclines downward from the tail end to the head end, and the pot body 300 is provided with an oil drain port 340 at the head end of the cold oil groove 330. By using the fact that the cold oil groove 330 is at the lowest point of the pot body 300, an oil drain port 340 is provided at the head end of the cold oil groove 330, and the bottom surface of the cold oil groove 330 inclines downward from the tail end to the head end, the oil in the pot body 300 can be more easily drained completely, with a compact structure and convenient and reliable use.

[0043] In some embodiments of the present utility model, such as Figure 2 shown, the base shell 100 is provided with an oil drainage assembly, the oil drainage assembly includes a switch valve body 610 and an oil drainage pipe 620, one end of the switch valve body 610 is docked with the oil drainage port 340 through the oil drainage pipe 620, the switch valve body 610 can be a mechanical valve or an electric valve. When the switch valve body 610 is opened, the oil in the pot body 300 can be discharged from the oil drainage pipe 620. When the switch valve body 610 is closed, the oil drainage port 340 is blocked, which is convenient and reliable to use.

[0044] In some embodiments of the present utility model, a filter screen assembly 700 is further provided in the pot body 300 above the bottom surface. The filter screen assembly 700 is provided with a plurality of filter holes (not shown in the figure). The filter screen assembly 700 can be placed in the pot body 300 and is located above the bottom surface. The aperture of the filter holes is relatively small, and the oil can pass through the filter holes, while the fried food is not easy to pass through the filter holes, reducing the amount of fried food deposited on the bottom surface of the pot body 300, thereby reducing the probability of the pot body 300 dry burning.

[0045] In some embodiments of the present utility model, the anti-dry burning electromagnetic frying furnace further includes an oscillation frequency detection module 800. The control module 510 drives the electromagnetic drive part 210 to operate through the drive module 520. The oscillation frequency detection module 800 is connected to the electromagnetic drive part 210 to detect the operating oscillation frequency of the electromagnetic drive part 210. The control module 510 is connected to the oscillation frequency detection module 800 to control the operation of the drive module 520 according to the operating oscillation frequency.

[0046] Specifically, the control module 510 formulates a PWM duty cycle signal according to the required heating power to control the operation of the drive module 520. The drive module 520 outputs an AC power supply signal with a first frequency to the electromagnetic coil 211. If the pot body 300 is placed in front of the electromagnetic coil 211, due to the load coupling between the electromagnetic coil 211 and the pot body 300, the oscillation frequency detection module 800 detects the second frequency oscillating on the electromagnetic coil 211. The second frequency will be lower than the first frequency. At this time, the control module 510 can know that the pot body 300 is placed in the electromagnetic frying furnace. When the bottom of the pot body 300 has a dry burning situation, the load coupled by the electromagnetic coil 211 will further increase. The oscillation frequency detection module 800 detects the third frequency oscillating on the electromagnetic coil 211. The third frequency is lower than the second frequency, and the control module 510 can judge that the pot body 300 has a dry burning situation.

[0047] Specifically, such as Figure 8As shown, the oscillation frequency detection module 800 includes a resonant capacitor CX5, a first sampling unit 810, and a second sampling unit 820. The resonant capacitor CX5 is connected in parallel with the electromagnetic drive unit 210. The sampling terminal of the first sampling unit 810 is connected to one end of the resonant capacitor CX5, and the sampling terminal of the second sampling unit 820 is connected to the other end of the resonant capacitor CX5. The output terminals of the first sampling unit 810 and the second sampling unit 820 are both connected to the control module 510. Both the first sampling unit 810 and the second sampling unit 820 can be composed of resistors. By detecting the terminal voltage of the resonant capacitor CX5 connected in parallel with both ends of the electromagnetic drive unit 210, and then combining the sampling voltages of the first sampling unit 810 and the second sampling unit 820, a frequency signal is obtained.

[0048] In some embodiments of the present utility model, the anti-dry-burning electromagnetic frying furnace further includes a temperature detection module 900. The temperature detection module 900 is disposed on the pot body 300, and the temperature detection module 900 is connected to the control module 510. The temperature detection module 900 can detect the oil temperature in the pot body 300, and the control module 510 controls the operation of the drive module 520 according to the oil temperature to prevent the temperature of the electromagnetic drive unit 210 from being too high and affecting the quality of the food.

[0049] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0050] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present utility model.
