DETAILED DESCRIPTION

[0028] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0029] A quick electric hot pot using a detachable pot body, such as Figure 1 , Figure 2 As shown, it includes a pot body and a heating plate 3, the pot body includes an inner pot body 1 and an outer pot body 2, the heating plate 3 is provided with at least two heating rings 4, the inner pot body 1 and the outer pot body 2 are independent structures that can be detached from each other, the outer pot body 2 has an inner annular wall 5, the upper end opening of the inner pot body 1 is integrally formed with an outward turn edge 6, the outward turn edge 6 is press-fitted with the inner annular wall 5, the inner annular wall 5 or the pot wall of the inner pot body 1 is inclined, and a heat-insulating cavity ring 7 is formed between the two.

[0030] In normal use, the present application only needs to guide the outer folded edge 6 of the inner pot body 1 to press against the inner annular wall 5, so that the inner pot body 1 can be embedded and assembled in the inner annular wall 5 of the outer pot body 2, which has the technical effect of convenient assembly; in the heating state, at least two heating rings 4 of the heating plate 3 provide heat for the inner pot body 1 and the outer pot body 2 respectively, so as to realize independent heating of the two, effectively improve the temperature rise rate of the inner pot body 1, and the split inner pot body 1 and the outer pot body 2 have more sufficient heat insulation compared with the integrated pot body, which effectively reduces the inner pot body 1 to the outer pot body 2, further improving the temperature rise rate of the inner pot body 1. It should also be noted that when producing the pot body, the stretching forming process can be used to separately produce the inner pot body 1 and the outer pot body 2, which has lower production costs than the die-casting process of the one-piece pot body; after use, due to the use of split and detachable inner pot body 1 and outer pot body 2, they can be disassembled and cleaned, which has the technical effect of convenient cleaning; in summary, the present application effectively reduces the production cost while ensuring the temperature rise rate of the inner pot body 1, and has the technical effect of convenient use and cleaning.

[0031] In order to improve the connection stability between the inner pot body 1 and the outer pot body 2, as Figure 3 , Figure 4 As shown, the outwardly turned edge 6 is a secondary bending structure, and the outwardly turned edge 6 and the pot wall cross-section of the inner pot body 1 are U-shaped to clamp the inner annular wall 5, thereby limiting the relative mobility of the inner pot body 1 and the outer pot body 2, and effectively improving the connection stability between the two.

[0032] It should be noted that if Figure 3 , Figure 4 As shown, a silicone ring 8 is embedded between the outward turning edge 6 and the pot wall of the inner pot body 1. The cross section of the silicone ring 8 has a clamp 9 for clamping the inner ring wall 5. On the one hand, heat insulation is achieved between the outward turning edge 6 and the inner ring wall 5, further reducing the heat transfer from the inner pot body 1 to the outer pot body 2. On the other hand, buffering of the inner pot body 1 is achieved, effectively preventing the inner pot body 1 from shaking and generating noise in the boiling state. In addition, the setting of the silicone ring 8 can give the inner pot body 1 a sinking range, thereby ensuring that the bottom surface of the inner pot body 1 is in full contact with the heating plate 3 without the need for very high dimensional accuracy.

[0033] To facilitate positioning of the heating plate 3 and the pot body, Figure 2 , Figure 3 As shown, the upper end surface of the heating plate 3 is provided with a central raised platform 10 and an edge depressed portion 11, the cross section of the edge depressed portion 11 is inclined downward outward, and the cross-sectional inclination angle of the bottom of the outer pot body 2 is consistent with the inclination angle of the edge depressed portion 11; through the cooperation between the central raised platform 10 and the inner circle of the bottom of the outer pot body 2, the center position of the pot body is limited, ensuring that the inner pot body 1 is aligned with the central raised platform 10, and the edge depressed portion 11 is additionally provided to cooperate with the inclined bottom of the outer pot body 2 to achieve further positioning of the pot body 1.

[0034] To ensure electrical safety, Figure 3 , Figure 5 As shown, the bottom of the heating plate 3 is covered with an insulating bottom cover 12, and the heating plate 3 is integrally formed with bolt columns 12-1 and is fastened with the insulating bottom cover 12 at intervals; by insulating the bottom surface of the heating plate 3, on the one hand, the safety of the electrical appliance is improved, and on the other hand, the heat transfer downward is reduced, thereby improving the utilization rate of the heat generated by the heating plate 3.

[0035] The specific structure of the heating plate 3 is as follows: Figure 3 , Figure 5 As shown, the heating plate 3 is specifically provided with three heating coils 4, namely, heating coil A4-1, heating coil B4-2 and heating coil C4-3. The heating coil A4-1 is located in the vertical projection of the outer pot body 2, the heating coil B4-2 is located in the vertical projection of the insulating cavity ring 7, and the heating coil C4-3 is located in the vertical projection of the inner pot body 1. The heating coil A4-1 alone provides heat for the outer pot body 2, and the heating coil C4-3 alone provides heat for the inner pot body 1, thereby meeting the technical requirements of separate heating, and the heating coil B4-2 is additionally provided, so that a heat source exists between the inner pot body 1 and the outer pot body 2, further preventing the inner pot body 1 from transferring heat to the outer pot body 2.

[0036] The inner pot body 1 of the present application is an independent structure, and the fixedly installed temperature controller cannot ensure that it is in full contact with the inner pot body 1, which may cause the risk of temperature control failure. Figure 2 , Figure 3 , Figure 5 As shown, a center hole 13 is opened in the center of the heating plate 3, and an aluminum cover 14 is slidably connected to the center hole 13. The aluminum cover 14 is supported and connected with a compression spring 15, and a jump-type thermostat 16 is fixedly installed on the lower surface of the aluminum cover 14; the compression spring 15 pushes the aluminum cover 14 upward, forcing the aluminum cover 14 to fully contact the bottom surface of the inner pot body 1, so that the jump-type thermostat 16 can realize real-time sensing and control of the bottom surface temperature of the inner pot body 1 through the aluminum cover 14, effectively eliminating the hidden danger of temperature control failure.

[0037] The aluminum cover 14 is slidably mounted on the heating plate 3 in the following manner: Figure 5 As shown, the lower surface of the heating plate 3 is symmetrically integrally formed with two sliding cylinders 17 around the central axis of the center hole 13, and the bottom end of the aluminum cover 14 is integrally formed with a clamping ear 18 that is clearance-matched with the sliding cylinder 17, thereby achieving the technical requirement of the aluminum cover 14 being slidably connected to the center hole 13 while reducing the space occupied; it should be noted that the bottom end of the sliding cylinder 17 is bolted to a limiting baffle 19, thereby limiting the sliding stroke of the aluminum cover 14 to prevent it from falling off.

[0038] In order to achieve the zoned temperature control requirements of the inner pot body 1 and the outer pot body 2, an auxiliary temperature sensor 20 is abutted against the outer wall of the outer pot body 2. The auxiliary temperature sensor 20 is fixed to the outer shell of the fast electric hot pot. The auxiliary temperature sensor 20 is used to control the opening and closing of the heating coil A4-1, thereby providing heat to the outer pot body 2. The actual temperature detected by the auxiliary temperature sensor 20 is individually controlled to open and close through the control circuit board, thereby achieving zoned temperature control of the inner pot body 1 and the pot body 2.

[0039] It should be noted that the upper opening of the inner pot body 1 is covered with a center cover 21, and after the inner pot body 1 is disassembled, the center cover 21 covers the upper opening of the inner ring wall 5; when the user needs to use the inner pot body 1 alone, the center cover 21 is covered to achieve the smoldering of the inner pot body 1. When the user needs to use it as a copper stove hot pot, after disassembling the inner pot body 1, the center cover 21 can be covered on the upper opening of the inner ring wall 5, which effectively improves the versatility of the present application.

[0040] The specific embodiments are merely explanations of the present invention and are not limitations of the present invention. After reading this specification, those skilled in the art may make modifications to the embodiments without any creative contribution as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
