Description

Technical Field

[0001] This utility model relates to an electric heating pot. Background Technology

[0002] Currently, most electric heating pot products on the market use a temperature sensor (NTC) to transmit the pot's temperature signal to the PCBA chip. Based on the real-time temperature preset program, the power is turned on to heat up if the temperature is not reached, and the power is turned off to keep the pot warm once the preset temperature is reached. The overall safety is entirely based on the accuracy of the transmitted signal and the stable operation of the software. If there is an error in the transmitted signal or the software is not working or is lagging behind, the heating plate will continue to heat, creating a safety hazard. Utility Model Content

[0003] The purpose of this invention is to overcome the above-mentioned shortcomings in the existing technology and to provide an electric heating pot with a reasonable structural design and greater safety.

[0004] The technical solution adopted by this utility model to solve the above problems is as follows: an electric heating pot, including a top cover, an inner pot, an outer shell, a heating component, and a bottom cover; the top cover is installed on the top of the outer shell; the bottom cover is installed on the bottom of the outer shell; the inner pot is disposed inside the outer shell; the heating component is disposed at the bottom of the inner pot; the heating component is provided with a temperature probe and a heating plate, both of which are fixed to the bottom of the inner pot; the feature is that a fuse is connected to the power cord of the heating plate, and the fuse is fixedly attached to the bottom of the inner pot.

[0005] The fuse described in this invention is fixed at the center of the bottom of the inner pot.

[0006] This utility model also includes a pressure relief valve cover and a pressure relief valve; the pressure relief valve is installed on the upper cover; the pressure relief valve cover is installed on the upper cover and covers the pressure relief valve.

[0007] This utility model also includes an anti-clogging inner cover, which is installed at the bottom of the upper cover.

[0008] This utility model also includes a sealing ring, which is installed at the bottom of the upper cover.

[0009] Compared with the prior art, this utility model has the following advantages and effects: while implementing electronic program temperature control, it adds a safety setting by adding a fuse to establish a protection program in a physical way. When the pot body temperature is too high, it directly intervenes and disconnects the circuit when there is a transmission signal error or the software is not working or is lagging behind, so as to achieve maximum safety.

[0013] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0014] This utility model embodiment includes a pressure relief valve outer cover 1, a pressure relief valve 2, an upper cover 3, an anti-clogging inner cover 4, a sealing ring 5, an inner pot 6, an outer shell 7, a heating assembly 8, a bottom cover 9, and a fuse 10.

[0015] The top cover 3 is installed on the top of the outer shell 7. The pressure relief valve 2 is installed on the top cover 3. The outer cover 1 of the pressure relief valve is installed on the top cover 3, covering the pressure relief valve 2. The anti-clogging inner cover 4 is installed at the bottom of the top cover 3 to prevent food from entering the vent hole of the top cover 3. The sealing ring 5 is installed at the bottom of the top cover 3 to seal the inner pot 6. The bottom cover 9 is installed at the bottom of the outer shell 7. The inner pot 6 is located inside the outer shell 7.

[0016] The heating element 8 is located at the bottom of the inner pot 6 and is connected to the power cord 10. The heating element 8 includes a temperature probe 11 and a heating plate 12, both fixed to the bottom of the inner pot 6. When the heating element 8 heats the inner pot 6, the temperature probe transmits the pot's temperature signal to the PCBA chip. If the temperature is not reached, the heating plate 12 is powered on to heat up; once the preset temperature is reached, the heating plate 12 is powered off to maintain the temperature.

[0017] A fuse 10 is connected to the power cord of the heating plate 12, and a fuse 11 is fixed to the center of the bottom of the inner pot 6. The fuse 11 is in close contact with the bottom of the inner pot 6 and can accurately sense the temperature. A protection program is established by physical means. When the pot temperature is too high, or when there is a transmission signal error, or when the software is not working or is lagging, the fuse 10 will directly trigger and disconnect the power supply to the heating plate 12 to achieve maximum safety. If there are multiple heating circuits, a separate fuse 10 must be added to each circuit.

[0018] Furthermore, it should be noted that the specific embodiments described in this specification may differ in the shape and name of their components. The above description is merely illustrative of the structure of this utility model. All equivalent or simple variations made based on the structure, features, and principles described in this utility model patent concept are included within the protection scope of this utility model patent.
