It combines the practicality of a cast iron pot with the beauty of enamel. The enamel pot has the advantages of fast heat conduction and uniform heating. The pot body is relatively thick and has good sealing performance.

[0003] The specification of Chinese patent CN219331284U discloses an energy-saving and scalding-proof cast iron enamel pot. When the utility model is in use, when the annular plate is embedded in the U-shaped plate, the pot cover and the enamel pot body are fixed to each other, preventing water vapor from lifting the pot cover, preventing the enamel pot body from losing heat too quickly, and preventing the water in the pot from easily overflowing from the enamel pot.

[0004] Since the average thickness of the cast iron enamel pot wall is 3.7mm and the bottom is 0.5mm, the enamel pot needs to go through a long preheating period when used before the temperature inside the enamel pot can reach the expected temperature. During this period, not only is the heating efficiency low and energy consumption high, but most of the heat will be wasted around the bottom of the pot, which is inconvenient for users and increases their usage costs. Utility Model Content

[0005] In view of the above-mentioned prior art, the technical problem to be solved by the utility model is that due to the large thickness of the pot wall of the enamel pot, the enamel pot needs to go through a long preheating period when in use before the temperature inside the enamel pot can reach the expected temperature, which makes it inconvenient for users to use and causes a waste of energy.

[0006] To solve the above problems, the utility model provides an energy-saving and scalding-proof cast iron enamel pot with a rapid heating system, including an enamel pot body, the enamel pot body including a cast iron layer, the cast iron layer is wrapped with an enamel layer, and the enamel layer is inlaid with a plurality of heating plates in a circular array with the central axis of the cast iron layer, the outer ring of the enamel pot body is provided with a heating base, the inner bottom wall of the heating base is fixedly connected with an electromagnetic coil, the upper end of the electromagnetic coil is fixedly connected with a heat conducting plate, the lower end of the enamel pot body is fixedly connected with a composite bottom film, the lower end of the composite bottom film is in contact with the upper end of the heat conducting plate, a plurality of heating rods are fixedly inlaid in the heating base, the upper end of the enamel pot body is fixedly connected with a sealing ring, the upper end of the sealing block is provided with a receiving groove, the upper end of the enamel pot body is provided with a pot cover, the sealing ring is located in the pot cover, the circular inner wall of the pot cover is fixedly connected with the sealing block, and the sealing block is completely matched with the receiving groove.

[0007] In the above energy-saving and scalding-proof cast iron enamel pot with a rapid heating system, when in use, the heating area of ​​the enamel pot is increased, and the enamel pot can be quickly heated, thereby effectively avoiding energy waste and facilitating use by users.

[0008] As a further improvement of the present application, a plurality of heating rods are distributed in a circular array around the central axis of the enamel pot body, and the inner wall of the heating base fits with the outer annular surface of the enamel pot body.

[0009] As a further improvement of the present application, the composite film includes a stainless steel circular plate and an aluminum plate, and the aluminum plate is fixedly embedded in the stainless steel circular plate.

[0010] As a further improvement of the present application, the lower end of the heating base is fixedly connected to a support base, and the longitudinal section of the support base is an isosceles trapezoid.

[0011] As another improvement of the present application, two handles are fixedly connected to the outer ring of the enamel pot body, and the handles and the pot handle of the pot lid are both made of heat insulating material.

[0012] As another improvement of the present application, a temperature sensor is fixedly connected to the front end of the heating base, and the temperature sensor is electrically connected to the heating rod and the electromagnetic coil respectively.

[0013] To sum up, in actual application, the bottom and outer wall of the enamel pot body are heated by starting the heating rod and the electromagnetic coil at the same time. The heat conduction plate and the composite bottom film can improve the heat conduction efficiency, and the heat receiving plate can increase the heating area of ​​the enamel pot body.

DETAILED DESCRIPTION

[0023] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0024] The first implementation method:

[0026] Figure 3 It is shown that: the outer ring of the enamel pot body 1 is provided with a heating base 2, the inner bottom wall of the heating base 2 is fixedly connected with an electromagnetic coil 3, the upper end of the electromagnetic coil 3 is fixedly connected with a heat conducting plate 4, and a plurality of heating rods 6 are fixedly embedded in the heating base 2. The heating rods 6 and the electromagnetic coil 3 heat the enamel pot body 1 at the same time, which can improve the heating efficiency and shorten the time consumed in the preheating period. The plurality of heating rods 6 are distributed in a ring array with the central axis of the enamel pot body 1, the inner wall of the heating base 2 is fitted with the outer ring surface of the enamel pot body 1, and the lower end of the heating base 2 is fixedly connected with a support seat 11, and the longitudinal section of the support seat 11 is an isosceles trapezoid. The support seat 11 can improve the stability of the enamel pot and facilitate user use.

[0027] Figure 4 and Figure 5It is shown that: the lower end of the enamel pot body 1 is fixedly connected with a composite bottom film 5, the lower end of the composite bottom film 5 is in contact with the upper end of the heat conducting plate 4, the upper end of the enamel pot body 1 is fixedly connected with a sealing ring 7, the upper end of the sealing ring 7 is provided with a receiving groove 8, the sealing ring 7 is located in the pot cover 9, the circular inner wall of the pot cover 9 is fixedly connected with a sealing block 10, the sealing block 10 is completely matched with the receiving groove 8, the sealing block 10 is embedded in the receiving groove 8, which can improve the sealing between the pot cover 9 and the enamel pot body 1, effectively avoid the rapid loss of heat in the pot, and improve the energy saving of the enamel pot.

[0028] Figure 6 It is shown that the composite film 5 includes a stainless steel circular plate 501 and an aluminum plate 502. The aluminum plate 502 is fixedly embedded in the stainless steel circular plate 501. The aluminum plate 502 can conduct heat evenly and has good thermal conductivity.
