Description

Technical Field

[0001] The utility model relates to the technical field of electric ceramic stoves, in particular to a heating plate installation structure and an electric ceramic stove. Background Art

[0002] An electric ceramic stove is a stove device that uses the thermal effect of electric current to convert electrical energy into thermal energy. Its main structure consists of a heating plate and a shell. The maximum temperature of an electric ceramic stove can reach about 700°C. Its stir-frying ability is comparable to that of a gas stove, and it can adapt to different cooking utensils. However, existing electric ceramic stoves are prone to sudden combustion, which can lead to safety accidents such as fires. During the research process, the applicant found that the sudden combustion of the electric ceramic stove is related to the melting of the plastic support column of the bottom plate at high temperature.

[0003] In order to make the heating plate conduct heat more evenly and prevent the user from directly touching the heating plate and causing burns, the existing electric ceramic stove usually needs to be provided with a pressure strip on the heating plate. In order to fix the pressure strip, plastic support columns are often provided on both sides of the heating plate. The pressure strip is fixed by connecting the two ends of the pressure strip to the plastic support columns. However, the plastic support columns are not resistant to high temperatures. Once the plastic melts, there is no appropriate heat dissipation measure or the ambient temperature continues to rise, it will cause a fire. Utility Model Content

[0004] In order to solve the above-mentioned problem, the utility model provides a heating plate installation structure, including a shell, a heating plate is arranged at the center of the bottom of the shell, a pressure strip is provided on the heating plate, and thermal insulation pads with through holes are clamped at both ends of the pressure strip. The fixing part is fixedly connected to the support column on the shell through the through hole on the thermal insulation pad, so that the heating plate is fixed in the shell through the pressure strip.

[0005] Furthermore, the heat insulating pad is in the shape of a pulley, and U-shaped clamping positions are provided at both ends of the pressure strip, and the pulley-shaped heat insulating pad is clamped on the U-shaped clamping position.

[0006] Furthermore, the thermal insulation pad is made of polyphenylene sulfide (PPS).

[0007] Furthermore, the thermal insulation pad is made of ceramic fiber or silica aerogel material.

[0008] Furthermore, the inner wall of the shell is coated with a flame retardant protective film.

[0009] Furthermore, the flame retardant protective film includes a nano-scale silicon nitride powder layer, a polycarbonate film layer, and a graphene layer which are stacked in sequence from top to bottom.

[0010] Furthermore, the pressure strip is in the shape of a bridge, which is formed by bending a long strip of metal sheet.

[0011] Furthermore, the two side edges of the pressure strip are bent downward to be in close contact with the heating plate.

[0012] Furthermore, the thickness of the layering strip is 0.5 to 1.5 mm.

[0013] An electric ceramic stove comprises any one of the above-mentioned heating plate mounting structures.

[0014] The beneficial effect is that when in use, the heating plate installation structure of the present application is turned over and placed in a preset area of ​​the electric ceramic stove, so that the bottom of the shell of the present application is in close contact with the microcrystalline plate or tempered glass plate on the electric ceramic stove. The present application clamps the heat insulation pads with through holes at both ends of the pressure strip instead of directly fixing the pressure strip with the support column. In this way, most of the heat on the pressure strip is blocked from being transferred to the support column, ensuring that the support column will not melt and cause safety problems such as fire. Compared with the existing electric ceramic stove, the heating plate installation structure designed by the present application can make the electric ceramic stove more flame retardant and have higher safety performance.
