Description

Technical Field

[0001] The utility model relates to the technical field of electric heating furnaces, in particular to an electric heating furnace with double heating positions. Background Art

[0002] A Chinese patent with announcement number CN220061845U discloses a multifunctional electric heating furnace, including a furnace body assembly, which is composed of a shell and a stainless steel bottom plate fixedly installed at the bottom of the shell; circular through grooves are opened on both sides of the top of the shell, and mirror stainless steel discs that can reflect light sources are snap-fitted on the two circular through grooves, and Y-shaped brackets are placed on the two mirror stainless steel discs, and heating coils are snap-fitted on the two Y-shaped brackets, and an isolation gap is formed between the heating coils and the mirror stainless steel discs to prevent heat from being conducted to the shell.

[0003] The electric heating furnace generates heat through the heating coil, and then reflects the light source through the mirror stainless steel disc. At this time, the heat absorbed by the shell is greatly reduced, so that a large amount of heat is concentrated on the object to be heated, thereby reducing the surface temperature of the shell.

[0004] However, when in use, the heating coil is protruding from the top of the shell, and no corresponding protective measures are provided, so burns may easily occur during use.

[0005] Therefore, a double-heating electric furnace is proposed. Utility Model Content

[0027] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0028] Please refer to Figures 1 to 7As shown, an embodiment of the utility model provides a double-heating position electric stove, comprising an electric stove body 1 with two heating positions and a protective mechanism 2, wherein the protective mechanism 2 is mounted on the top of the electric stove body 1, and a heating plate on the electric stove body 1 is located inside the protective mechanism 2, and the protective mechanism 2 for isolating the heat emitted by the heating plate comprises a first protective cover 201 and a second protective cover 202, both of which are arranged in an annular shape, and the second protective cover 202 is slidably sleeved on the inner side of the first protective cover 201 through a telescopic component, and when the cookware is in contact with the electric stove body 1, the protective cover 201 is provided with a plurality of protective covers, and the protective cover 202 ... When heating is performed, the second protective cover 202 can be pressed into the first protective cover 201 by the cookware so that the bottom of the cookware contacts the heating plate. When the cookware leaves the heating plate, the upper end of the second protective cover 202 extends out of the first protective cover 201 under the action of the telescopic assembly to shield the side of the heating plate. A first thermal insulation layer 205 is provided on the inner side of the second protective cover 202, and a second thermal insulation layer 206 is provided on the inner side of the first protective cover 201. In this embodiment, the thickness of the first thermal insulation layer 205 and the thickness of the second thermal insulation layer 206 are both set to 10mm-15mm.

[0029] In this embodiment, the first thermal insulation layer 205 and the second thermal insulation layer 206 are both configured as hydrophobic thermal insulation ceramic fiber layers. This configuration can effectively prevent the first thermal insulation layer 205 and the second thermal insulation layer 206 from losing their thermal insulation effect after contacting water.

[0030] Specifically, the telescopic assembly includes a guide member and a spring 207. The bottom of the first protective cover 201 is bent and formed to have an annular groove 2014. The guide member is fixedly connected to the top of the annular groove 2014. The inner wall of the first protective cover 201 is provided with a slide groove 2011 connected to the annular groove 2014. The outer wall of the second protective cover 202 is fixedly connected with a sleeve 2021. The sleeve 2021 extends from the slide groove 2011 into the annular groove 2014 and then slides onto the guide member. The spring 207 is sleeved on the guide member. The bottom of the spring 207 is pressed against the bottom of the guide member, and the upper end of the spring 207 is against the bottom of the sleeve 2021.

[0031] By adopting the above technical solution, when the heating plate is heating the cooker, if the size of the bottom of the cooker is smaller than the inner diameter of the protective mechanism 2, the protective mechanism 2 can directly provide heat insulation protection for the protruding side of the heating plate, that is, at this time, the bottom of the cooker does not apply pressure to the second protective cover 202. At this time, the upper end of the second protective cover 202 extends from the inside of the first protective cover 201 under the elastic force of the spring 207, so that the second protective cover 202 can protect the protruding heating plate. If the size of the bottom of the cooker is larger than the inner diameter of the protective mechanism 2, the second protective cover 202 in the protective mechanism 2 can be pressed into the first protective cover 201, so that the bottom of the cooker can still fully contact with the heating plate. After the heating of the cooker is completed, when the cooker is removed from the heating plate, the second protective cover 202 can be quickly extended from the first protective cover 201 under the elastic force of the spring 207 to provide heat insulation protection for the protruding side of the heating plate, thereby being suitable for cookers of different sizes.

[0032] In this embodiment, the guide member includes a guide rod 203 and a cap bolt 204. The guide rod 203 is fixed at the top of the annular groove 2014. A threaded hole is opened at the bottom of the guide rod 203. The cap bolt 204 is threadedly fixed in the threaded hole. The bottom of the spring 207 is pressed on the top of the nut of the spring 207. This arrangement facilitates the installation of the sleeve 2021 and the spring 207 on the guide rod 203. The specific operation is to put the sleeve 2021 on the guide rod 203, and then put the spring 207 on the guide rod 203, and then thread the cap bolt 204 into the threaded hole opened at the bottom of the guide rod 203.

[0033] Specifically, in order to facilitate fixing the protective mechanism 2 on the electric heating furnace body 1, the bottom of the first protective cover 201 is bent to provide a flange 2012, and the flange 2012 is provided with a mounting hole 2013 for fixing with a screw. The lower end of the screw passes through the mounting hole 2013 and is threadedly fixed to the top of the electric heating furnace body 1.

[0034] The above description shows and describes several preferred embodiments of the utility model, but as mentioned above, it should be understood that the utility model is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the utility model concept described herein through the above teachings or the technology or knowledge of the relevant field. The changes and modifications made by those skilled in the art do not deviate from the spirit and scope of the utility model, and should be within the scope of protection of the attached claims described in the utility model.
